     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO, AND
SHOULD BE READ IN CONJUNCTION WITH, THE MORE DETAILED INFORMATION AND FINANCIAL
STATEMENTS APPEARING ELSEWHERE IN THIS PROSPECTUS. SEE "RISK FACTORS" FOR
INFORMATION THAT SHOULD BE CAREFULLY CONSIDERED BY PROSPECTIVE INVESTORS.

                                  THE COMPANY
   
     Castle Dental Centers, Inc. (the "Company") develops and operates
integrated dental networks through affiliations with general, orthodontic and
multi-specialty dental practices in the United States. The Company currently
conducts operations in the states of Texas, Florida and Tennessee and has
entered into definitive agreements to acquire certain assets of and manage
dental practices headquartered in Long Island, New York, serving the New York
metropolitan area, and Little Rock, Arkansas, with offices in Arkansas, Oklahoma
and Louisiana. The Company also has entered into a letter of intent to acquire
certain assets of and manage a dental practice located in Austin, Texas which
the Company believes will complement its existing operations in Austin, Texas.
The Company establishes integrated dental networks through affiliations with
dental practices providing quality care in selected markets across the United
States with a view to achieving broad geographic coverage within those markets.
The Company seeks to achieve operating efficiencies by consolidating and
integrating affiliated practices into regional networks, realizing economies of
scale in such areas as marketing, administration and purchasing and enhancing
the revenues of its affiliated dental practices by increasing both patient
visits and the range of specialty services offered. As of October 15, 1996, the
Company provided management services to 35 dental centers with approximately 85
affiliated dentists, orthodontists and other dental specialists. Upon
consummation of the New York, Arkansas and Austin, Texas transactions, the
Company will manage 60 dental centers with approximately 225 affiliated
dentists, orthodontists and other dental specialists.
    
     The Company was formed in 1981 by Jack H. Castle, D.D.S. and Jack H.
Castle, Jr., as a single location, multi-specialty dental practice in Houston,
Texas. From 1982 through 1996, the Company expanded to a total of nine locations
with 35 dentists in the Houston metropolitan area. During this period the
Company developed, implemented and refined the integrated dental network
approach which it intends to utilize as a basis for its national expansion.

     The Company's objective is to make each of its dental networks the leading
group dental care provider in each market it serves. The Company applies
traditional retail principles of business and marketing techniques to the
practice of dentistry, including locating practices in high-profile locations,
offering more affordable fees and payment plans, expanding the range of services
offered, increasing market share through aggressive advertising and offering
extended office hours. By using the Castle Dental Centers' approach to managing
affiliated dental practices, the Company believes it will enable affiliated
dentists, orthodontists and other dental specialists to focus on delivering
quality patient care and to realize significantly greater productivity than
traditional individual and small-group dental practices.
   
     The Company believes that the provision of a full range of dental services
through an integrated network is attractive to managed care payors and intends
to continue to pursue managed care contracts. The Company currently maintains an
aggregate of ten capitated contracts and preferred provider arrangements
covering approximately 21,000 members, and, upon consummation of the Pending
Acquisitions, the Company will have an aggregate of 64 capitated contracts and
preferred provider arrangements covering approximately 70,000 members. The
Company believes that the continued development of its networks will assist it
in negotiating national and regional capitated arrangements with managed care
payors.
    
     The Company intends to utilize the practice management principles employed
in its Houston operations to establish a consistent national identity for its
business. Moreover, the Company believes that its experience and expertise in
managing multi-specialty dental group practices, as well as the development of
name recognition associated with the name "Castle Dental Centers," will
provide its affiliated dental

                                       3
<PAGE>
practices with a competitive advantage in attracting and retaining patients and
realizing practice efficiencies.

     Dental care services in the United States are generally delivered through a
fragmented system of local providers, primarily sole practitioners, or small
groups of dentists, orthodontists or other dental specialists, practicing at a
single location with a limited number of professional assistants and business
office personnel. However, dental, orthodontic and other specialty practices
have followed the trend of the health care industry generally and are
increasingly forming larger group practices in which a separate professional
management team handles personnel, management, billing, marketing and other
business functions. The Company believes that this trend will continue. The
annual aggregate domestic market for dental services is estimated to be
approximately $46.5 billion for 1995, representing approximately 4.2% of total
health care expenditures in the United States, and is projected to reach $79.1
billion by 2005. The dental services market has grown at a compound annual
growth rate of approximately 8.0% from 1980 to 1995, and is projected to grow at
a compound annual growth rate of approximately 6.0% through the year 2005.
   
     There presently are nine Castle Dental Centers operating in the Houston,
Texas area and four additional centers in Houston in various stages of
development. In May 1996, the Company acquired the assets of and entered into
long-term management agreements with 1st Dental Care, P.A., a dental practice
with 12 locations in the Tampa/Clearwater, Florida area, and Mid-South Dental
Centers, P.C., a dental practice with six dental centers in various locations in
Tennessee. In August 1996, the Company increased its dental practices under
management in Texas by acquiring the assets of Horizon Dental Centers, a dental
practice with four dental centers in Fort Worth, Texas and four dental centers
in Austin, Texas (collectively with the acquisition of 1st Dental Care and
Mid-South Dental Centers, the "Completed Acquisitions"). In August 1996, the
Company entered into a definitive agreement to acquire certain assets of and
enter into a long-term management agreement with American Dental Centers, a
dental practice based in Long Island, New York with 12 dental centers in the New
York metropolitan area (the "New York Acquisition"). In August 1996, the
Company also entered into a definitive agreement to acquire certain assets of
and enter into a long-term management agreement with United DentalCare, a dental
practice based in Little Rock, Arkansas that operates nine dental centers in
Arkansas, Oklahoma and Louisiana (the "Arkansas Acquisition"). In September
1996, the Company entered into a letter of intent to acquire certain assets of
and enter into a long-term management agreement with Southwest Dental
Associates, a dental practice based in Austin, Texas that operates four dental
centers in the Austin, Texas metropolitan area (the "Austin Acquisition"). The
New York Acquisition, the Arkansas Acquisition and the Austin Acquisition are
referred to collectively as the "Pending Acquisitions," and together with the
Completed Acquisitions, the "Acquisition Transactions." The New York
Acquisition is expected to close contemporaneously with, and is mutually
conditioned on, the closing of this offering, and the Arkansas Acquisition and
the Austin Acquisition are expected to close within 30 days of the closing of
this offering.
     The consideration for the Completed Acquisitions consisted of approximately
$9.3 million in cash, $4.5 million in Seller Notes and 612,243 shares of the
Company's Common Stock. The consideration for the Pending Acquisitions consists
of approximately $27.3 million in cash and 840,000 shares of the Company's
Common Stock, assuming an initial public offering price of $10.00. The Company
will also assume approximately $955,000 of long-term debt in connection with the
Pending Acquisitions. Under the terms of each of the definitive agreements for
the Arkansas Acquisition and the letter of intent for the Austin Acquisition,
additional cash consideration will be paid if the acquired practice achieves
specified operating results subsequent to the completion of the transaction.
    
     The Company's strategy is to develop integrated networks for the provision
of dental services through practice affiliations that provide quality,
cost-effective dental care in target markets. Key elements of this strategy are
to (i) provide high-quality, comprehensive, one-stop family dental health care;
(ii) actively pursue acquisitions and DE NOVO development in target markets;
(iii) apply traditional retail principles of business to dental care; and (iv)
market its networks to managed care entities.

    extraordinary loss on retirement of the Company's 12% Senior Subordinated
    Notes ("Senior Subordinated Notes"), net of income tax effect of
    $1,211,000, which will be recognized in the period this offering is
    completed.

(3) Represents primarily gain or loss on sale of assets and interest income.
   
(4) Prior to the Reorganization, significant operations of the Company were
    conducted through a subchapter S corporation and accordingly were not
    subject to federal and state income taxes (see Notes 1 and 6 to the
    Company's Audited Combined Financial Statements). If all of the Company's
    operations had been subject to income taxes, net income (loss) would have

(5) Shares used in calculating net income per share include the weighted average
    outstanding shares plus the number of shares (at an assumed public offering
    price of $10.00 per share) for the year ended December 31, 1995 and the six
    months ended June 30, 1996, the proceeds of which would be necessary to
    repay the portion of the Company's debt that funded the $6,000,000 payment
    to Jack H. Castle, D.D.S. in connection with the Reorganization. See
    "Unaudited Pro Forma Combined Financial Information" and "Certain
    Transactions." Historical weighted average shares outstanding and net
    income (loss) per share were 5,515,000 and $(.44), respectively, for the

                                  RISK FACTORS

     In addition to the other information contained in this Prospectus,
prospective investors should consider carefully the factors listed below in
evaluating an investment in the shares of Common Stock offered hereby.
   
ACQUISITION STRATEGY AND LIMITATION ON GROWTH

     The Company's strategy is to develop comprehensive dental networks through
practice affiliations. Key elements of this strategy are the acquisition of the
assets of dental practices and the introduction of specialty dental services in
target market areas, the entry into management services relationships with such
groups and the utilization of the acquired practices as a base from which to
expand in the target markets. 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.
There can be no assurance that the Company will successfully establish practice
affiliations with additional dental practices. In addition, the Company's
ability to expand is dependent on factors such as its ability to attract
additional dentists to affiliated dental practices, to adapt or adjust the
Company's structure to comply with present or future state legal requirements
affecting the Company's contractual arrangements with dental, orthodontic or
other specialty practice groups, and to obtain regulatory approval and comply
with regulatory and licensing requirements applicable to dentists and facilities
operated and services offered by dentists. Moreover, the Company's ability to
expand may be limited by state licensing requirements which do not normally
provide for reciprocity among states with respect to licensure of dentists.
Unless otherwise required by law, the Company does not intend to seek
stockholder approval for future acquisitions, and the stockholders of the
Company will be dependent upon management's judgment with respect to such
transactions. There can be no assurance that the Company will be able to achieve
planned growth, that the assets of dental practices will continue to be
available for acquisition by the Company, that the Company will be able to
realize expected operating and economic efficiencies from recent and pending
acquisitions, or that the addition of such practice groups will be profitable.

Systems," "Business -- Dental Network Development" and
"Business -- Operations."

RISKS RELATING TO PENDING ACQUISITIONS

NEW YORK ACQUISITION

     The Company has entered into a definitive agreement with respect to the New
York Acquisition and the closing of the New York Acquisition is a condition to
the closing of this offering. The New York Acquisition represents a significant
acquisition for the Company, both in terms of purchase price and revenues. The
American Dental Centers practice is heavily dependent on reimbursement
arrangements with certain labor organizations and welfare funds, which generally
have terms of one to two years and provide for payment on a capitated basis, and
relationships with other payor groups, including traditional insurance and
preferred provider arrangements. American Dental Centers is a party to over 50
such capitated contracts and preferred provider arrangements which account for
over 70% of its total revenues. Most of these capitation contracts are
terminable by either party with 60 to 90 days' notice. Certain features of the
capitation contracts could be interpreted by regulatory authorities as
constituting the transaction of insurance business and could result in
regulatory enforcement actions against the Company. In such event, the Company
could be required either to seek licensure as an insurance company or change the
form of the business relationships with the parties to such contracts. There can
be no assurance that after the closing of the New York Acquisition the Company
will be able to continue American Dental Centers' existing arrangements with
such labor organizations, welfare funds and other payor groups. The loss of one
or more of the largest of such reimbursement arrangements could have a material
adverse effect on the profitability of the Company.
     Jules V. Lane D.D.S., the founder of American Dental Centers, is also the
owner of American Medical and Life Insurance Company ("AMLI"), which markets
preferred provider programs of which American Dental Centers is a significant
provider. AMLI's preferred provider program, managed care program and
    
                                       8
<PAGE>
   
other insurance related business is not being acquired by the Company. Dr. Lane
will join the Company's Board of Directors and enter into a three-year
employment agreement with the Company pursuant to which Dr. Lane will remain
active in the management of and strategic planning for American Dental Centers.
At the closing of the New York Acquisition, the Company will enter into certain
contractual arrangements with AMLI which will provide that in markets in the
State of New York served by the dental practices managed by the Company (i) AMLI
and the Company will each include information regarding the programs and
services of the other in their respective marketing materials, (ii) AMLI will
maintain preferred provider relationships with dental practices managed by the
Company and offer such dental practices as preferred providers to AMLI
policyholders and other covered parties and (iii) AMLI and the Company will
share certain facilities and personnel. Each party has a right of first refusal
to extend such arrangements to states other than New York. Because Dr. Lane will
be a Director of the Company and the owner of AMLI, there is a potential for
conflict of interest on the part of Dr. Lane with respect to matters involving
AMLI and the Company. Dr. Lane will not participate in the negotiation of such
matters on behalf of the Company or vote on such matters as a Director of the
Company.

     Because of the size of the New York Acquisition, the percentage of American
Dental Centers' revenue which is derived from capitated and preferred provider
arrangements, the possibility of loss of one or more of the largest of such
reimbursement arrangements and the Company's lack of prior experience in the New
York metropolitan area, the New York Acquisition represents significant risks to
the Company. The Company will rely on Dr. Lane to maintain the Company's revenue
base in the New York metropolitan area. There can be no assurance that the
Company will be able to integrate the New York Acquisition into its existing
operations or that it will be able to maintain or expand its revenue base in the
New York metropolitan area. See " -- Acquisition Strategy and Limitation on
Growth" and " -- Integration of Affiliated Dental Practices and Management
Information Systems."

ARKANSAS ACQUISITION AND AUSTIN ACQUISITION

     The Company has entered into a definitive agreement with respect to the
Arkansas Acquisition and a letter of intent with respect to the Austin
Acquisition. Although both the Arkansas Acquisition and the Austin Acquisition
are expected to close within 30 days of the closing of this offering, there can
be no assurance that either of these transactions will be consummated, and the
consummation of these transactions is not a condition to the closing of this
offering. See "Unaudited Pro Forma Combined Financial Information." If
consummated, there can be no assurance that these acquisitions will be
successfully integrated into the Company's existing operations. See
" -- Acquisition Strategy and Limitation on Growth" and " -- Integration of
Affiliated Dental Practices and Management Information Systems."
    
GOVERNMENT REGULATION
   
GENERAL

     The dental 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 dentistry and state insurance regulation.
See "Business -- Government Regulation."

FEE-SPLITTING; CORPORATE PRACTICE OF DENTISTRY

     The laws of many states prohibit dentists from splitting fees with
non-dentists and prohibit non-dental entities such as the Company from engaging
in the practice of dentistry or employing dentists to practice dentistry. The
specific restrictions against the corporate practice of dentistry, 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-dental entity from controlling the professional assets of a dental practice
(such as patient records and payor contracts), employing dentists to practice
dentistry (or, in certain states, employing dental hygienists or dental
assistants), controlling the content of a dentist's advertising or professional
practice or sharing professional fees with non-dental entities. The laws of many
states also prohibit dental practitioners from paying any portion of fees
received for dental services in consideration for
    
                                       9
<PAGE>
   
the referral of a patient. In addition, many states impose limits on the tasks
that may be delegated by dentists to dental assistants.

     State dental boards do not generally interpret these prohibitions as
preventing a non-dental entity from owning non-professional assets used by a
dentist in a dental practice or providing management services to a dentist
provided that the following conditions are met: a licensed dentist has complete
control and custody over the professional assets; the non-dental entity does not
employ or control the dentists (or, in some states, dental hygienists or dental
assistants); all dental services are provided by a licensed dentist; licensed
dentists have control over the manner in which dental care is provided and all
decisions affecting the provision of dental 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 dental practice acts do
not address or provide any restrictions concerning the manner in which companies
account for revenues from a dental practice subject to the above-noted
restrictions relating to control over the professional activities of the dental
practice, ownership of the professional assets of a dental practice and payments
for management services.

     The Company does not control the practice of dentistry or employ dentists
to practice dentistry. Moreover, in states in which it is prohibited, the
Company does not employ dental hygienists or dental assistants. The Company
provides management services to its 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 its affiliated dental practices within the meaning of those terms
under the state dental practice acts and believes that its operations comply
with the above-described laws to which it is subject. There can be no assurance,
however, that a review of the Company's business relationships by courts or
other 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 dentistry and their interpretation vary from state to
state and 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 affiliated dental practices will not be successfully
challenged or that the enforceability of the provisions of any management
services agreement will not be limited. The laws and regulations of certain
states in which the Company may seek to expand may require the Company to change
the form of relationships entered into with dental practices in a manner which
may restrict the Company's operations or how providers may be paid in those
states or may prevent the Company from acquiring the non-dental assets of such
practices or managing dental practices in those states. Similarly, there can be
no assurance that the laws and regulations of the states in which the Company
presently maintains operations will not change or be interpreted in the future
either to restrict or adversely affect the Company's existing or future
relationships with dental practitioners in those states.

STATE INSURANCE REGULATION

     In addition, 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 are subject to
interpretation by regulators with broad discretion. As the Company or its
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 the affiliated dental
practices are engaged in the business of insurance because some of the managed
care contracts to which the Company is a party 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 the
affiliated practices are determined to be engaged in the business of insurance,
the Company could be required either to seek
    
                                       10
<PAGE>
   
licensure as an insurance company or to change the form of its relationships
with third-party payors and 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 legislative proposals will be adopted in the future, if any,
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 adopted by Congress 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 dental
practitioners affiliated with dental practices managed by the Company, and lower
profitability for affiliated practices. See "Business -- Government
Regulation."

RELIANCE ON AFFILIATED DENTAL PRACTICES
   
     The Company receives fees for management services provided to its
affiliated dental practices under management services agreements. However, the
Company is an independent manager only and does not employ dentists,
orthodontists or other specialists to practice dentistry or in any way control
the practices of the dentists, orthodontists or other specialists employed by
the affiliated dental practices. In many cases, a significant portion of the
Company's management services revenue is dependent on revenue generated by the
affiliated dental practices. In other cases, the Company's management fee is
based on its costs and expenses of providing mangagement services. While the
laws of some states permit the Company to participate in the negotiations by
affiliated dental practices of managed care contracts, preferred provider
arrangements and other negotiated price agreements, the affiliated dental
practices are the contracting parties for all such relationships, and the
Company is dependent on its affiliated dental practices for the success of such
relationships. Accordingly, the profitability of such payor relationships as
well as the performance of dentists, orthodontists or other specialists employed
by such dental practices affects the Company's profitability. Should the
Company's affiliated dental practices experience difficulty in hiring or
retaining qualified dentists, orthodontists or other specialists, or should the
revenues of affiliated dental practices decrease materially, it could have a
material adverse effect on the financial performance of the Company.
    
INTEGRATION OF AFFILIATED DENTAL PRACTICES AND MANAGEMENT INFORMATION SYSTEMS

     Although the Company has been in operation since 1981, prior to May 1996,
the Company's operations were conducted entirely in the Houston, Texas area, and
the Company has limited experience in managing affiliated dental practices
outside of the Houston, Texas area. The entry of the Company into new geographic
markets by acquisition will require the Company to maintain and establish payor
and client relationships which may be different in nature than those which the
Company has historically had and the Company will need to attract and retain
competent and experienced management personnel in each market it enters. The
Company may also be dependent on former owners and management to maintain its
payor and customer relationships. In addition, the expansion into new markets
requires the implementation of new or expanded reporting and tracking systems,
management information systems and other operating systems. There can be no
assurance that the Company will be able to expand its organizational structure,
maintain or establish such relationships or attract the management and other
personnel necessary to permit it to integrate into its existing operations
affiliated dental practices located outside of the Houston, Texas area.
   
     In connection with its expansion into new market areas, the Company will be
required to interface its financial information system with existing practice
management systems at the affiliated dental practices, which may be different
from those used by the Company. Any significant delay or increase in expense
associated with the conversion and integration of management information systems
used by affiliated dental practices could have a material adverse effect on the
successful integration of affiliated dental practices. See " -- Acquisition
Strategy and Limitation on Growth."
    
                                       11
<PAGE>
NEED FOR ADDITIONAL FINANCING

     The Company's acquisition and expansion programs will require substantial
capital resources. Capital is needed not only for the acquisition of the assets
of affiliated dental practices, but also for the effective integration,
operation and expansion of the affiliated practices. The affiliated practices
may require capital for renovation and expansion and for the addition of dental
equipment and technology. The Company believes that its existing cash resources
together with the net proceeds from this offering, cash flow from operations and
borrowings available under the Bank Credit Facility (as hereinafter defined)
will be sufficient to meet the Company's anticipated acquisition, expansion and
working capital needs for the next 18 months. Thereafter, however, the Company
may be required either to raise additional capital or curtail its expansion
plans. The Company may obtain such financing through additional borrowings or
the issuance of additional equity or debt securities, either of which could have
an adverse effect on the value of the shares of Common Stock offered by this
Prospectus. Although the Company currently believes that it will be able to
secure additional financing, there can be no assurance that the Company will be
able to raise additional capital when needed on satisfactory terms or at all.
Any limitation on the Company's ability to obtain additional financing or
complete a public offering could have a material adverse effect on the Company.

COMPETITION

     The Company is under competitive pressures for the acquisition of the
assets of, and the provision of management services to, additional dental
practices. Management is aware of several companies with established operating
histories and greater resources than the Company which are pursuing the
acquisition of general and specialty dental practices and the management of such
practices. Additionally, affiliated dental practices compete locally with sole
practitioners and group practices of dental, orthodontic and other specialty
services in the Company's markets. There can be no assurance that the Company or
its affiliated dental practices will be able to compete effectively with such
competitors, that additional competitors will not enter the market or that such
competition will not make it more difficult to acquire and provide management
services to dental practices on terms beneficial to the Company. See
"Business -- Competition."

RISKS RELATED TO GOODWILL
   
     As of June 30, 1996, the Company's total pro forma adjusted assets were
approximately $65.0 million, of which approximately $50.2 million, or 77%, was
goodwill, net of accumulated amortization. Goodwill is the excess of the
purchase price over the fair market value of the net assets of acquired
businesses (which net assets include any separately identifiable intangible
assets). There can be no assurance that the value of the goodwill will ever be
realized by the Company. Goodwill is being amortized on a straight-line basis
over a 40-year period.

     All of the goodwill on the Company's pro forma adjusted balance sheet as of
June 30, 1996 is related to the Acquisition Transactions with $33.5 million
being attributable to the Pending Acquisitions. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations." The Company
evaluates each acquisition and establishes an appropriate amortization period
based on the underlying facts and circumstances. Subsequent to each acquisition,
the Company continuously reevaluates such facts and circumstances to determine
if the related goodwill continues to be realizable and if the amortization
period continues to be appropriate.

     Amortization of the goodwill on the Company's pro forma adjusted balance
sheet as of June 30, 1996 will produce an annual amortization expense of
approximately $1.3 million. Of this amount, the Pending Acquisitions are
expected to produce annual amortization expense of approximately $838,000.
Purchases of additional businesses which result in the recognition of additional
goodwill would cause amortization expense to increase further. Although the net
unamortized balance of goodwill on the Company's pro forma balance sheet as of
June 30, 1996 was not considered to be impaired, any future determination that a
significant impairment has occurred would require the write-off of the impaired
portion of unamortized goodwill, which would have a material adverse effect on
the Company's results of operations. See "Unaudited Pro Forma Combined
Financial Information."
    
                                       12
<PAGE>
RISKS ASSOCIATED WITH MANAGED CARE CONTRACTS; CAPITATED FEE REVENUE
   
     The Company believes that its success will be dependent, in part, on its
ability to negotiate, on behalf of the affiliated practices, contracts with
health maintenance organizations ("HMOs"), insurance companies, self insurance
plans and other private third-party payors pursuant to which services will be
provided on some type of fee-for-service or capitated basis by some or all of
its affiliated practices. Under certain capitated contracts, the health care
provider accepts a predetermined amount per patient per month as its sole
payment in exchange for providing certain necessary covered services to
enrollees. Such contracts shift much of the risk of providing health care from
the payor to the provider. To the extent that the Company's affiliated dental
practices enter into these types of arrangements, they are exposed to the risk
that the cost of providing dental care required by such contracts exceeds the
amount that the affiliated dental practice receives for providing such dental
care. Most of these contracts are terminable by either party on 60 to 90 days
notice. Under certain other capitated contracts, the predetermined amount may be
subject to periodic adjustment to limit the risk that may be shifted from the
payor to the provider. For the 12 months ended December 31, 1995 and the six
months ended June 30, 1996, the Company derived approximately 13% and 15% of
total pro forma adjusted net patient revenues, respectively, from such capitated
contracts. To the extent the Company's affiliated dental practices enter into
additional managed care contracts, the Company may expect greater predictability
of revenues but greater unpredictability of expenses due to the fluctuating
costs of the services provided. There can be no assurance that the Company will
be able to negotiate on behalf of the affiliated practices satisfactory
arrangements on a capitated basis, regardless of the amount of risk-sharing. In
addition, to the extent that patients or enrollees covered by certain of such
contracts require more frequent or extensive care than is anticipated, operating
margins may be reduced, or the revenues derived from such agreements may be
insufficient to cover the costs of the services provided. As a result,
affiliated practices may incur additional costs which would reduce or eliminate
any earnings under these contracts.

     Following the New York Acquisition, the Company will have a significant
presence in the New York metropolitan area. For the year ended December 31,
1995, in excess of 70% of the annual net patient revenues of American Dental
Centers was derived from capitated contracts or preferred provider arrangements,
and the nine largest relationships of this type accounted for approximately 54%
of the net patient revenues of American Dental Centers. The majority of these
arrangements are terminable by either party at the end of each year or on 30 to
90 days prior notice, and certain of the preferred provider relationships are
terminable by either party at any time. The unreplaced loss of one or more of
the largest capitated care or preferred provider arrangements by American Dental
Centers could have a material adverse effect on the Company's business and
prospects.
    
DEPENDENCE UPON SENIOR EXECUTIVES
   
     The Company is dependent upon the continued services of its executive
officers, especially its Chairman and Chief Executive Officer, Jack H. Castle,
Jr. Additionally, following the New York Acquisition, the Company will be
dependent upon the continued services of Jules V. Lane D.D.S., the owner of
American Dental Centers, to facilitate the integration of American Dental
Centers with the Company. The loss of the services of Jack H. Castle, Jr., Jules
V. Lane D.D.S. or any of the Company's other senior executive officers could
have a material adverse effect on the Company's business and prospects. Certain
of the Company's senior executive officers, including Jack H. Castle, Jr., do
not have an employment agreement and are not otherwise subject to a covenant not
to compete or other agreement which would restrict their ability to compete
against the Company should their employment by the Company be terminated for any
reason. See "Management."
    
POTENTIAL LIABILITY AND INSURANCE

     Due to the nature of its business, the Company from time to time becomes
involved as a defendant in medical malpractice lawsuits brought against
affiliated dental practices or dentists employed by such practices. In addition,
the Company could be involved in litigation in which it is alleged that the
Company has been negligent in performing its duties under management services
agreements. The Company

                                       13
<PAGE>
maintains professional and general liability insurance in amounts deemed
appropriate by management based upon its assessment of historical claims and the
nature and risks of its business. There can be no assurance, however, that an
existing or future claim or claims will not exceed the limits of available
insurance coverage, that any insurer will remain solvent and able to meet its
obligations to provide coverage for any such claim or claims or that such
coverage will continue to be available or available with sufficient limits and
at a reasonable cost to insure adequately and economically the Company's
operations in the future. A judgment against the Company in excess of such
coverage could have a material adverse effect on the Company.
   
CONTROL BY THE CASTLE FAMILY

     Following the closing of this offering, members of the Castle Family will
beneficially own approximately 29.9% (28.0%, if the Underwriters' over-allotment
option is exercised in full) of the outstanding shares of Common Stock. As a
result, following the closing of this offering, if the Castle Family were to
vote as a group, the Castle Family could exert a significant influence over the
outcome of corporate actions requiring stockholder approval and the election of
the Company's Board of Directors. In addition, this ownership may have the
effect of discouraging unsolicited offers to acquire the Company. See
"Principal and Selling Stockholders."

BENEFITS TO INSIDERS

     In connection with the Reorganization, the Company incurred $13.5 million
of indebtedness and paid $6.0 million to Jack H. Castle, D.D.S., a director of
the Company, to acquire a dental practice owned by Dr. Castle. In the same
transaction, the Company entered into a Deferred Compensation Agreement with Dr.
Castle pursuant to which the Company agreed to pay Dr. Castle a total of
$2,630,000 in 20 quarterly installments. See "Certain Transactions."
Approximately $2.4 million of the proceeds of this offering will be used to
prepay all amounts owed by the Company to Dr. Castle under the Deferred
Compensation Agreement. Loretta Castle, the wife of Dr. Castle and the mother of
Jack H. Castle, Jr., a director of the Company, is selling 500,000 shares of
Common Stock owned by her in this offering.

     Approximately $20.0 million of the proceeds of this offering will be used
to fund the cash portion of the purchase price of the New York Acquisition.
Jules V. Lane D.D.S., who will become a Director of the Company on the closing
of the New York Acquisition, is the owner of American Dental Centers. See
"Business -- Pending Acquisition" and "Management -- Executive Compensation
and Employment Arrangements."

     In addition, approximately $7.5 million of the proceeds will be used to
repay the Company's 12% Senior Subordinated Notes due 2002 held by the Pecks
Investors. Mr. Cresci, a Director of the Company, is a Managing Partner of Pecks
Management Partners Ltd., the investment advisor to the Pecks Investors. See
"Certain Transactions."

NO PRIOR MARKET FOR COMMON STOCK: POSSIBLE VOLATILITY OF STOCK PRICE
    
     Prior to this offering, there has been no public market for the Company's
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 this
offering. The initial public offering price of the Common Stock will be
determined through negotiations between the Company and the Underwriters. See
"Underwriting" for a description of the factors to be considered in
determining the initial public offering price. The market price of the Common
Stock could be subject to significant fluctuations in response to variations in
financial results or announcements of material events by the Company or its
competitors. Regulatory changes, developments in the health care industry or
changes in general conditions in the economy or the financial markets could also
adversely affect the market price of the Common Stock.

SHARES ELIGIBLE FOR FUTURE SALE

     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 this offering.

                                       14
<PAGE>
   
     After giving effect to the shares of Common Stock offered hereby, the
closing of the Pending Acquisitions and the conversion of the Series A
Convertible Preferred Stock upon the closing of this offering, the Company will
have outstanding 11,696,980 shares of Common Stock. Of these shares, the
5,500,000 shares (6,325,000 shares if the Underwriters' over-allotment option is
exercised in full) of Common Stock sold in this offering will be freely tradable
without restriction or limitation under the Securities Act of 1933, as amended
(the "Securities Act"), except to the extent such shares are subject to the
agreement with the Underwriters described below, and except for any shares
purchased by "affiliates," as that term is defined under the Securities Act,
of the Company. The remaining 6,196,980 shares are "restricted securities"
within the meaning of Rule 144 adopted under the Securities Act ("Rule 144").
The restricted shares were issued and sold by the Company in private
transactions in reliance upon exemptions from registration under the Securities
Act.
    
     The Company, its directors and executive officers and all of the
stockholders of the Company have agreed that, for a period of 180 days after the
date of this Prospectus, they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any shares of Common Stock, except in the case of the Company,
in certain limited circumstances, including issuing up to 2,000,000 shares of
Common Stock in connection with acquisitions to parties that agree to be bound
by the same restrictions on offers and sales.
   
     The Company anticipates that prior to the consummation of this offering,
the Company will have outstanding under the Plan options to purchase an
aggregate of approximately 380,500 shares of Common Stock, and at or shortly
following consummation of this offering the Company anticipates that it will
issue options to purchase up to 350,000 shares of its Common Stock under the
Plan and the Directors' Plan. The Company intends to register the shares
issuable upon exercise of options granted under the Plan and the Directors' Plan
and, upon such registration, such shares will be eligible for resale in the
public market without restriction, except for Directors and other affiliates of
the Company who will be subject to volume limitations under Rule 144. Following
the consummation of this offering, the Company will also continue to have
outstanding the GulfStar Warrant, which is presently exercisable for 113,158
shares of Common Stock at $5.50 per share, and two Seller Notes, presently
convertible into 139,757 shares of Common Stock at a conversion price of $6.75
per share, all of which shares will be eligible for resale subject to the
volume, holding period and certain other limitations of Rule 144 upon their
exercise. See "Shares Eligible for Future Sale" and "Management -- Stock
Option Plans."
    
CERTAIN ANTI-TAKEOVER PROVISIONS

     Certain provisions of the Company's Certificate of Incorporation and
By-laws and of Delaware law could, together or separately, discourage potential
acquisition proposals, delay or prevent a change in control of the Company and
limit the price that certain investors might be willing to pay in the future for
shares of the Common Stock. The Company's Certificate of Incorporation provides
for "blank check" preferred stock which may be issued without stockholder
approval and certain provisions of the Company By-laws 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 By-laws. The Company also is subject to Section 203 of the
Delaware General Corporation Law which, subject to certain exceptions, prohibits
a Delaware corporation from engaging in any of a broad range of business
combinations with any "interested stockholder" for a period of three years
following the date that such stockholder became an interested stockholder. See
"Description of Capital Stock."

IMMEDIATE AND SUBSTANTIAL DILUTION
   
     The purchasers of the shares of Common Stock offered hereby will experience
immediate and substantial dilution in the net tangible book value of their
shares of Common Stock in the amount of $9.77 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
    
                                       15
<PAGE>
this offering may experience further dilution in the net tangible book value per
share of the Common Stock of the Company.

                                  THE COMPANY

     Castle Dental Centers, Inc. was formed as a Delaware corporation in
December 1995 to succeed to the business of Family Dental, a Texas corporation,
which was wholly-owned by the Castle Family. The Company is a holding company
and conducts its business through a number of wholly-owned subsidiaries. The
Company's executive offices are located at 1360 Post Oak Boulevard, Suite 1300,
Houston, Texas 77056, and its telephone number is (713) 513-1400.

                                USE OF PROCEEDS
   
     The net proceeds from the sale of the 5,000,000 shares of Common Stock
offered by the Company hereby are estimated to be approximately $45.5 million
(approximately $53.2 million if the Underwriters' over-allotment option is
exercised in full) after deducting the underwriting discounts and commissions
and estimated offering expenses based on an assumed initial public offering
price of $10.00 per share. The Company will not receive any proceeds from Common
Stock sold by the Selling Stockholder.

     The Company has entered into definitive purchase agreements relating to the
New York Acquisition and the Arkansas Acquisition. Approximately $20.0 million
of the net proceeds of this offering will be used to fund the cash portion of
the purchase price of the New York Acquisition, $2.6 million of the net proceeds
of this offering will be used to fund the cash portion of the purchase price of
the Arkansas Acquisition, and $4.6 million will be used to fund the cash portion
of the purchase price of the Austin Acquisition.

     The Company also intends to use approximately $7.5 million of the net
proceeds to repay the Company's 12% Senior Subordinated Notes due in 2002 (the
"Senior Subordinated Notes"). The Senior Subordinated Notes were issued by the
Company in December 1995 to provide funds for the Reorganization and the
acquisition of affiliated dental practices. In connection with the
Reorganization, the Company paid $6.0 million to Jack H. Castle, D.D.S. to
acquire a dental practice owned by Dr. Castle.

     The Company intends to use approximately $6.1 million of the net proceeds
to repay a portion of the total indebtedness outstanding under the Amended and
Restated Credit Agreement (the "Bank Credit Facility") between the Company and
NationsBank of Texas, N.A. ("NationsBank") which was incurred to finance
certain of the Company's acquisitions. The Bank Credit Facility provides for a
term loan, revolving credit facility and advancing term loan which expire or
mature, as applicable, on June 15, 2001, June 30, 1997 and June 30, 2001,
respectively, and bear interest at variable rates which are based upon (a)
either (i) NationsBank's base rate or (ii) the London interbank offering rates
("LIBOR") plus (b) a margin which varies according to (i) the ratio of the
Company's funded debt to EBITDA, each as defined in the Bank Credit Facility,
(ii) the type of loan (i.e. base rate or LIBOR loan) and (iii) whether the loan
is a term loan, revolving credit loan or advancing term loan. As of June 30,
1996, the interest rate on the Bank Credit Facility was 8.94%. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and Note 2 to the Company's
Audited Financial Statements included elsewhere in this Prospectus for a
description of the interest rate and other terms of the Bank Credit Facility.

     Approximately $4.5 million of the net proceeds will be used to retire
seller financed subordinated debt issued by the Company to acquire affiliated
dental practices ("Seller Notes"). The Seller Notes mature at various times
from May 2001 to August 2001, and are accelerated at the closing of this
offering. Three of these Seller Notes, in the aggregate principal amount of
approximately $3.54 million, bear interest at 10% per annum. The remaining two
Seller Notes, in the aggregate principal amount of approximately $960,000, bear
interest at the rate of 6.36% per annum. An aggregate of $943,363 of the Seller
Notes is convertible at the option of the holder into shares of the Company's
Common Stock at a conversion price of $6.75 per share, subject to antidilution
adjustments and automatic annual increase in conversion price.
    
                                       16
<PAGE>
   
     Approximately $2.4 million of the proceeds will be used to prepay all
amounts owed by the Company to Jack H. Castle, D.D.S. pursuant to a Deferred
Compensation Agreement with Dr. Castle, effective as of December 18, 1995, which
agreement provides for quarterly payments in the amount of $131,500 to be made
to Dr. Castle until December 31, 2000 in respect of compensation not paid to Dr.
Castle prior to the acquisition of Jack H. Castle, D.D.S., Inc. The Deferred
Compensation Agreement with Dr. Castle was entered into in connection with the
acquisition by the Company of the non-dental assets of Jack H. Castle, D.D.S.,
Inc. in December 1995, of which Dr. Castle was the sole owner.
    
     The Company plans to use the balance of the net proceeds for acquisitions,
market development, working capital and general corporate purposes. The Company
is currently in discussions with several potential acquisition candidates, but
except as otherwise described herein has not entered into any binding agreements
with respect to any acquisitions. Pending such uses, the net proceeds will be
invested in short-term, fixed income obligations of investment grade.

                                DIVIDEND POLICY

     The Company has never paid cash dividends and does not anticipate paying
cash dividends in the foreseeable future. It is the present intention of the
Board of Directors to reinvest all earnings in the business of the Company to
support the future growth of its operations. The Bank Credit Facility currently
prohibits the payment of cash dividends. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

                                    DILUTION
   
     The net tangible book value of the Company at June 30, 1996, was a deficit
of approximately $15.9 million, or $3.73 per share of Common Stock. Net tangible
book value per share represents the amount of the Company's stockholders'
equity, less intangible assets, divided by the number of shares of Common Stock
issued and outstanding. Net tangible book value dilution per share represents
the difference between the amount per share paid by purchasers of shares of
Common Stock in this offering and the pro forma net tangible book value per
share of Common Stock immediately after completion of this offering. Shares of
Common Stock sold in this offering by the Selling Stockholder are included in
the calculation of shares of Common Stock outstanding, but the proceeds from the
sale of those shares do not increase the Company's stockholders' equity. After
giving effect to the sale of 5,000,000 shares of Common Stock offered by the
Company hereby (at an assumed initial public offering price of $10.00 per
share), the application of the estimated net proceeds therefrom as described
under "Use of Proceeds," and the consummation of the Pending Transactions, the
pro forma net tangible book value of the Company as of June 30, 1996 would have
been $2.7 million or $0.23 per share. This represents an immediate increase in
pro forma net tangible book value of $3.96 per share to stockholders as of June
30, 1996, and an immediate dilution in pro forma net tangible book value of
$9.77 per share to purchasers of Common Stock in this offering. The following
table illustrates the dilution per share:

(1) Gives effect to (i) the sale of the 5,000,000 shares of Common Stock offered
    by the Company hereby (at an assumed initial public offering price of $10.00
    per share) and the application of the net proceeds therefrom as described
    under "Use of Proceeds," (ii) the Acquisition Transactions, and (iii) the
    Reorganization, as if each of such transactions had occurred as of January
    1, 1995. See "Unaudited Pro Forma Combined Financial Information."
    
(2) The pro forma statements of operations do not reflect a $1,895,000
    extraordinary loss on retirement of the Senior Subordinated Notes, net of
    income tax effect of $1,211,000, which will be recognized in the period this
    offering is completed.

(3) Represents primarily gain or loss on sale of assets and interest income.
   
(4) Prior to the Reorganization, significant operations of the Company were
    conducted through a subchapter S corporation and accordingly were not
    subject to federal and state income taxes (see Notes 1 and 6 to the
    Company's Audited Combined Financial Statements). If all of the Company's
    operations had been subject to income taxes, net income (loss) would have
    been ($1,698,000) and $210,000 for the year ended December 31, 1995 and for
    the six months ended June 30, 1995, respectively. Subsequent to December 31,
    1995, the Company's operations are subject to income taxes and such taxes
    have been reflected in the historical consolidated statement of operations
    data for the six-month periods ended June 30, 1996. See "Unaudited Pro
    Forma Combined Financial Information."

(5) Shares used in calculating net income per share include the weighted average
    outstanding shares plus the number of shares (at an assumed public offering
    price of $10.00 per share) for the year ended December 31, 1995 and the six
    months ended June 30, 1996, the proceeds of which would be necessary to
    repay the portion of the Company's debt that funded the $6,000,000 payment
    to Jack H. Castle, D.D.S. in connection with the Reorganization. See
    "Unaudited Pro Forma Combined Financial Information" and "Certain
    Transactions." Historical weighted average shares outstanding and net
    income (loss) per share were 5,515,000 and $(.44), respectively, for the
    year ended December 31, 1995 and 5,569,000 and $.01, respectively, for the
    six months ended June 30, 1996.

(6) Gives effect to (i) the sale of 5,000,000 shares of Common Stock offered by
    the Company hereby (at an assumed initial public offering price of $10.00
    per share) and the application of the net proceeds therefrom as described
    under "Use of Proceeds," (ii) the conversion of the Series A Convertible
    Preferred Stock into 1,244,737 shares of Common Stock, and (iii) the

               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following Unaudited Pro Forma Combined Balance Sheet as of June 30,
1996 and the Unaudited Pro Forma Combined Statements of Operations for the year
ended December 31, 1995 and the six months ended June 30, 1996 have been
prepared to reflect adjustments to the Company's historical financial position
and results of operations to give effect to the transactions described below.
The Unaudited Pro Forma Combined Balance Sheet reflects such transactions as if
they had occurred as of June 30, 1996, and the Unaudited Pro Forma Combined
Statements of Operations for the year ended December 31, 1995 and the six months
ended June 30, 1996 reflect such transactions as if they had occurred as of
January 1, 1995.

     Effective December 31, 1995, as part of a reorganization and
recapitalization plan (collectively with the financing arrangements discussed in
the following paragraph, the "Reorganization"), the Company merged with and
succeeded to the business of Family Dental. Family Dental was formed in 1981 to
provide management services to Jack H. Castle, D.D.S., Inc., a professional
corporation, which operated a dental practice in Houston, Texas. In December
1995, the Company acquired all the outstanding stock and certain assets of Jack
H. Castle, D.D.S., Inc. and entered into an agreement to provide practice
management services to a newly-established professional corporation, Jack H.
Castle, D.D.S., P.C., which succeeded to the dental practice of the professional
corporation acquired by the Company. See Notes 1, 2 and 9 to the Company's
Audited Combined Financial Statements and "Certain Transactions."
   
     In connection with the Reorganization, the Company entered into a
Securities Purchase Agreement (the "Securities Purchase Agreement") with three
investors represented by Pecks Management Partners Ltd. (the "Pecks
Investors") pursuant to which the Company issued 1,244,737 shares of Series A
Convertible Preferred Stock and the Senior Subordinated Notes. At the same time,
the Company entered into the Bank Credit Facility with NationsBank, which
provided for a term loan of $6.0 million and a revolving credit facility of $3.0
million. In May 1996 the Company amended the Bank Credit Facility to, among
other things, increase the amount available under the term loan to $16.0
million. See Notes 2, 4 and 10 to the Company's Combined Financial Statements.

     In May 1996, the Company acquired the assets and assumed certain
liabilities of 1st Dental Care headquartered in Clearwater, Florida and
Mid-South Dental Centers headquartered in Nashville, Tennessee, and entered into
management services agreements with each of those groups. In August 1996, the
Company increased its dental practices under management in Texas by acquiring
the assets and assuming certain liabilities of Horizon Dental Centers, a group
dental practice with four offices in Fort Worth, Texas and four offices in
Austin, Texas. Additionally, the Company has entered into definitive agreements
with respect to the New York Acquisition and the Arkansas Acquisition and a
letter of intent with respect to the Austin Acquisition. The New York
Acquisition is expected to close contemporaneously with, and is mutually
conditioned upon, the closing of this offering, and the Arkansas and Austin
Acquisitions are expected to close within 30 days of the closing of this
offering.

     The Unaudited Pro Forma Combined Balance Sheet as of June 30, 1996 gives
effect to (i) the sale of 5,000,000 shares of Common Stock offered by the
Company hereby (at an assumed initial public offering price of $10.00 per share)
and the application of the net proceeds therefrom, as described in "Use of
Proceeds," (ii) the conversion of the Series A Convertible Preferred Stock into
1,244,737 shares of Common Stock, and (iii) the Acquisition Transactions entered
into or pending subsequent to June 30, 1996, as if each of such transactions had
occurred as of June 30, 1996. The Unaudited Pro Forma Combined Statements of
Operations for the year ended December 31, 1995 and the six months ended June
30, 1996, give effect to (i) the sale of 5,000,000 shares of Common Stock
offered by the Company hereby (at an assumed initial public offering price of
$10.00 per share) and the application of net proceeds therefrom as described in
"Use of Proceeds," (ii) the Acquisition Transactions and (iii) the
Reorganization, as if each of such transactions had occurred as of January 1,
1995.
    
     The pro forma combined financial statements have been prepared by the
Company based on the historical financial statements of the Company and the
dental practices acquired or to be acquired in the Acquisition Transactions, the
financial statements of which are included elsewhere in this Prospectus. These
pro forma combined financial statements are presented for illustrative purposes
only and are not necessarily indicative of the results that would have been
obtained if the transactions had occurred on the dates indicated or that may be
realized in the future. The pro forma information should be read in conjunction
with the Company's Audited Combined Financial Statements and the Unaudited
Condensed Consolidated Interim Financial Statements and the Notes thereto and
the historical financial statements of the dental practices acquired or to be
acquired in the Acquisition Transactions and the notes thereto included
elsewhere in this Prospectus.

     The value of the Common Stock issued was based upon management's estimate
     of the fair market value thereof as of the date of the purchase agreement
     relating to the Horizon Dental Centers acquisition ($8.50 per share). The
     long-term debt consists of (i) $1.0 million in Seller Notes, payable in
     quarterly installments plus interest at 10% through December 2001, and (ii)
     $2.1 million in additional debt incurred under the Bank Credit Facility
     (see Note 10 to the Company's combined financial statements). The excess of
     cost over the fair value of the net assets acquired will be amortized over
     the term of the management services agreement entered into in connection
     with the acquisition, which is 40 years.

     The Company plans to use the net increase in cash and cash equivalents for
     acquisitions, market development, working capital and general corporate

     will be invested in short-term, fixed-income obligations of investment
     grade.

     The value of the Common Stock to be issued is based upon an assumed initial
     public offering price of $10.00 per share. The excess of cost over the fair
     value of the net assets acquired will be amortized over the terms of the
     management services agreements entered into in connection with the
     acquisitions, which is 40 years.

     Pursuant to the terms of the Arkansas Acquisition agreement, additional
     consideration may be payable if operating income exceeds a certain level
     for the twelve-month period ended December 31, 1996. The additional
     consideration will be an amount equal to $6,000 for each $1,000 of
     operating income in excess of the defined level. The consideration, if any,
     will be payable 50% in cash and 50% in Company Common Stock.

     The letter of intent entered into in connection with the Austin Acquisition
     provides that additional consideration may be payable if earnings before
     interest, taxes, depreciation and amortization ("EBITDA") exceed a
     certain level for the twelve-month period ended December 31, 1997. The
     additional consideration will be an amount equal to six times the amount of
     EBITDA in excess of the defined level. The consideration, if any, is
     payable in cash and shall not exceed $500,000.
     Any additional consideration payable under the terms of the agreements will
     be recorded as excess of cost over fair value of net assets acquired when
     paid.

(E)   The Arkansas and Austin Acquisitions are expected to close within 30 days
      of the closing of this offering; however, there can be no assurance that
      the acquisitions will be consummated. Without giving effect to the
      acquisitions, the Company's pro forma as adjusted balance sheet data would

         NOTES TO UNAUDITED PRO FORMA COMBINED STATEMENT OF OPERATIONS

(A)  Represents the historical Consolidated Statements of Operations data of the
     Company, which includes the operations of 1st Dental Care and Mid-South
     Dental Centers, acquired in May 1996, from the dates of acquisition.

(B)   Represents the combined historical statements of operations data of the
      affiliated dental practices acquired in the Completed Acquisitions for the
      year ended December 31, 1995 and the six months ended June 30, 1996 or the
      period from January 1, 1996 through the acquisition date, as appropriate.
      The historical statements of operations represent continuing operations
      and do not include a $112,000 extraordinary gain recognized by 1st Dental
      Care for the year ended December 31, 1995.

(C)   Offering adjustments represent those adjustments resulting from this
      offering that will affect the historical statements of operations on a
      continuing basis. The pro forma statements of operations do not reflect
      the $1,895,000 extraordinary loss on retirement of the Senior Subordinated
      Notes, net of income tax effect of $1,211,000, that will be recognized in
      the period this offering is completed.

(D)  Represents the combined historical statements of operations data of the
     Pending Acquisitions for the year ended December 31, 1995 and the six
     months ended June 30, 1996.
   
(E)   The Arkansas and Austin Acquisitions are expected to close within 30 days
      of the closing of this offering. However, there can be no assurance that
      these acquisitions will be consummated. Without giving effect to these
      acquisitions, the pro forma statement of operations data would be as
      follows:

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

     The following discussion of the results of operations and financial
condition of the Company should be read in conjunction with the Company's
Audited Combined Financial Statements, Unaudited Condensed Consolidated Interim
Financial Statements and the Notes thereto included elsewhere in this
Prospectus.

OVERVIEW

     From its inception in 1981 until 1990, the Company opened three dental
centers in Houston, Texas. Beginning in 1991, the Company began an expansion
program, opening five new dental centers by the end of 1995. At the end of 1995,
the Company managed eight dental centers with 37 affiliated dentists in the
Houston metropolitan area, with net patient revenues of $18.3 million. Each of
the Company's centers in Houston was developed DE NOVO, by identifying a
desirable location, entering into a lease agreement, and building out the leased
space to the Company's specifications. The Company staffs DE NOVO dental centers
with a combination of experienced Company personnel and new employees. The
Company opened its ninth dental center in April 1996.
   
     Beginning in the first quarter of 1996, the Company began to identify group
dental practices outside of Houston, Texas as potential acquisition candidates
with a view to expanding the Company's operations into new markets. Since May
1996, the Company has completed the acquisition of three affiliated dental
practices and has entered into two definitive agreements and a letter of intent
to acquire a total of three others. As a result of the recent rapid expansion of
the business through acquisitions and the Company's limited period of
affiliation with these practices, the Company believes that period-to-period
comparisons set forth below may not necessarily be meaningful nor representative
of future results. For additional information regarding the pro forma financial
effect of the Company's acquisitions, see "Unaudited Pro Forma Combined
Financial Information."

     Certain of the affiliated dental practices derive a significant portion of
their revenues from managed care contracts, preferred provider arrangements and
other negotiated price agreements. While the laws of some states permit the
Company to participate in the negotiations by affiliated dental practices of
managed care contracts, preferred provider arrangements and other negotiated
price agreements, the affiliated dental practices are the contracting parties
for all such relationships, and the Company is dependent on its affiliated
dental practices for the success of such relationships. See "Risk
Factors -- Risks Associated with Managed Care Contracts; Capitated Fee Revenue"
and "Reliance on Affiliated Dental Practices," and "Business_-- Dental
Network Development -- Management Services Agreement."
    
ACQUISITION AND AFFILIATION SUMMARY
   
     Since May 1, 1996, the Company has acquired certain assets of and entered
into long-term management agreements with 1st Dental Care, Mid-South Dental
Centers and Horizon Dental Centers, three affiliated dental practices that have
expanded its market presence into the Tampa/Clearwater area in Florida, the
Nashville and Chattanooga areas in Tennessee, and the Austin and Fort Worth
areas in Texas, respectively. In addition, the Company has entered into
definitive agreements with respect to the New York Acquisition and the Arkansas
Acquisition, and has entered into a letter of intent with respect to the Austin
Acquisition. The New York Acquisition is expected to occur contemporaneously
with, and is mutually conditioned on, the closing of this offering, and the
Arkansas Acquisition and the Austin Acquisition are expected to close within 30
days thereafter.

     The acquisition of affiliated dental practices in Florida, Tennessee and
Texas added 26 dental centers with 53 affiliated dentists to the Company for an
aggregate consideration of approximately $9.3 million in cash, $4.5 million in
Seller Notes and 612,243 shares of the Company's Common Stock. An aggregate of
$943,363 of the Seller Notes is convertible into Common Stock at a conversion
price of $6.75 per share, subject to antidilution adjustments and automatic
annual increase in conversion price. An aggregate of 75,000 shares of Common
Stock is being held in escrow in connection with the acquisition of Horizon
Dental Centers, which shares will be released if certain earnings milestones are
met. The purchase price for the New York Acquisition is $20.0 million in cash
and $5.0 million in shares of Common Stock valued at the initial public offering
price, the purchase price for the Arkansas Acquisition is $2.6 million in cash
and
    
                                       33
<PAGE>
   
185,000 shares of Common Stock, and the purchase price for the Austin
Acquisition is $4.8 million in cash and $1.6 million in shares of Common Stock,
valued at the initial public offering price. The Company will also assume debt
obligations of $553,000 in connection with the Arkansas Acquisition and $183,000
in connection with the Austin Acquisition. Under the terms of the definitive
agreement for the Arkansas Acquisition and the letter of intent for the Austin
Acquisition, additional cash consideration will be paid if the acquired practice
achieves specified operating results subsequent to the completion of the
transaction. Upon completion of the New York Acquisition, the Arkansas
Acquisition and the Austin Acquisition, the Company will manage 60 dental
centers with approximately 225 affiliated dentists in seven states.
    
     The Company currently is in discussions with a number of dentists and
owners of group dental practices concerning the potential for future affiliation
with the Company. There can be no assurance that these discussions will result
in new practice affiliations in the near future or at all.

</TABLE>
SIX MONTHS ENDED JUNE 30, 1996 COMPARED TO SIX MONTHS ENDED JUNE 30, 1995

     The Company acquired the assets of and entered into management agreements
with two group dental practices in May 1996, the results of which are included
in the Company's operating results from the dates of acquisition. Changes in
results of operations from the first six months of 1995 to the first six months
of 1996 were caused primarily by affiliations with these two group dental
practices. For periods prior to 1996, the Company's operations were conducted
entirely in Houston, Texas.

     NET PATIENT REVENUES -- Net patient revenues increased from $9.1 million
for the six months ended June 30, 1995 to $10.7 million for the six months ended
June 30, 1996, an increase of $1.6 million or 17.9%. Approximately $1.4 million
of the increase was attributable to the acquisition of 1st Dental Care,

                                       34
<PAGE>
headquartered in Clearwater, Florida, and Mid-South Dental Centers,
headquartered in Nashville, Tennessee, that the Company completed on May 19 and
May 31, 1996, respectively, with the remaining $200,000 primarily attributable
to the opening of the Company's ninth dental center in Houston in April 1996.
   
     DENTISTS' SALARIES -- Dentists' salaries, which include salaries and
productivity-based compensation paid to affiliated dentists, increased from $1.6
million for the six months ended June 30, 1995 to $1.9 million for the six
months ended June 30, 1996, an increase of $258,000 or 16%. The increase
resulted primarily from the addition of dentists' compensation at the 18 dental
offices acquired in Florida and Tennessee. Expressed as a percentage of net
patient revenues, dentists' salaries decreased from 17.7% to 17.5% for the six
months ended June 30, 1995 and 1996, as the growth in net patient revenues was
greater relatively than the increase in dentists' salaries. See
"Business -- Dental Network Development -- Dentist Employment Agreements."
    
     CLINICAL SALARIES -- Salaries and wages paid to clinical staffs increased
from $884,000 for the six months ended June 30, 1995 to $1.5 million for the six
months ended June 30, 1996, an increase of $651,000 or 73.6%. The addition of
the clinical staff salaries in Florida and Tennessee accounted for $452,000 of
the increase, with the remaining $200,000 attributable to increased staff levels
in anticipation of the opening of the ninth dental center in Houston in April
1996. Expressed as a percentage of net patient revenues, clinical salaries
increased from 9.7% to 14.3% for the six months ended June 30, 1995 and 1996,
respectively.

     DENTAL SUPPLIES AND LABORATORY FEES -- Dental supplies and laboratory fees
increased from $1.1 million for the six months ended June 30, 1995 to $1.4
million for the six months ended June 30, 1996, an increase of $266,000 or
24.5%. Dental supplies and laboratory fees at the Florida and Tennessee
operations accounted for $130,000 of the increase from the first six months of
1995 to the first six months of 1996. The use of higher cost materials to enable
general dentists to perform certain specialized procedures and the stocking of
the Company's newly-opened dental center in Houston accounted for most of the
remaining increase. Expressed as a percentage of net patient revenues, dental
supplies and laboratory fees increased from 12.0% to 12.6% for the six months
ended June 30, 1995 and 1996, respectively.

     RENTAL AND LEASE EXPENSE -- Rental and lease expense increased from
$381,000 for the six months ended June 30, 1995 to $486,000 for the six months
ended June 30, 1996, an increase of $105,000 or 27.5%. Rental expense in Florida
and Tennessee of $77,000 in the period since the acquisitions were completed in
May 1996 accounted for most of the increase. Expressed as a percentage of net
patient revenues, rental and lease expense increased from 4.2% to 4.5% for the
six months ended June 30, 1995 and 1996, respectively.

     ADVERTISING AND MARKETING -- Advertising and marketing expense increased
from $420,000 for the six months ended June 30, 1995 to $533,000 for the six
months ended June 30, 1996, an increase of $112,000 or 26.8%. Higher
expenditures for television advertising and a direct mail advertising campaign
conducted in conjunction with the opening of a new dental center in Houston in
April accounted for most of the $71,000 increase in advertising expense, with
the Florida and Tennessee acquisitions adding $41,000. Expressed as a percentage
of net patient revenues, advertising and marketing expense increased from 4.6%
to 5.0% for the six months ended June 30, 1995 and 1996, respectively.

     DEPRECIATION AND AMORTIZATION -- Depreciation and amortization increased
from $167,000 for the six months ended June 30, 1995 to $334,000 for the six
months ended June 30, 1996, an increase of $167,000 or 100%. Higher depreciation
expense resulted from capital expenditures in late 1995 at the Company's new
corporate office and the relocation of one of the Company's dental centers. In
addition, the acquisition of the Florida and Tennessee operations added
depreciation expense of $35,000 and goodwill amortization of $29,000 in the 1996
period.

     OTHER OPERATING EXPENSES -- Other operating expenses decreased from $1.3
million for the six months ended June 30, 1995 to $1.2 million for the six
months ended June 30, 1996, a decrease of $100,000, or 7.8%. Other operating
expenses include certain expenses related to the operation of the Company's
dental centers and bad debt expense incurred in the financing of patient
receivables at the affiliated dental practices. Lower bad debt expense resulting
from improved credit and collection procedures accounted for the reduction,
partially offset by the addition of $64,000 of other operating expenses at

                                       35
<PAGE>
the Company's newly acquired dental centers in Florida and Tennessee. Expressed
as a percentage of net patient revenues, other operating expenses decreased from
14.0% to 11.0% for the six months ended June 30, 1995 and 1996, respectively.

     GENERAL AND ADMINISTRATIVE -- General and administrative expense decreased
from $2.9 million for the six months ended June 30, 1995 to $2.4 million for the
six months ended June 30, 1996, a decrease of $506,000 or 17.3%. Reduced
compensation paid to the Company's owners accounted for most of the decrease in
general and administrative expense. This was partially offset by the addition of
$187,000 in general and administrative expense incurred at the Florida and
Tennessee group dental practices in the 1996 period. Expressed as a percentage
of net patient revenues, general and administrative expense decreased from 32.2%
to 22.6% for the six months ended June 30, 1995 and 1996, respectively.

     INTEREST EXPENSE -- Net interest expense increased from $5,000 for the six
months ended June 30, 1995 to $1.1 million for the six months ended June 30,
1996. In the period from December 1995 through May 1996, the Company borrowed
approximately $17.5 million in order to fund the Reorganization and the
acquisition of affiliated dental practices in Florida and Tennessee, resulting
in increased net interest expense in the first half of 1996. In addition, the
amortization of the discount on the Senior Subordinated Notes was $261,000 in
the six-month period ended June 30, 1996.

     INCOME TAXES -- Prior to 1996, the Company did not accrue significant
corporate income taxes because a major portion of the Company's operations was
conducted through a Subchapter S corporation, which resulted in no corporate
income taxes being assessed against the profits of that company. Subsequent to
the Reorganization in December 1995, all of the Company's operations became
subject to corporate income taxes. For the six months ended June 30, 1996, the
provision for income taxes was $19,000 based on an estimated tax rate of 39.0%.
Income taxes accrued for prior periods related solely to the dental practice
management operations.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994

     NET PATIENT REVENUES -- Net patient revenues increased from $17.1 million
for the year ended December 31, 1994 to $18.3 million for the year ended
December 31, 1995, an increase of $1.2 million or 6.9%. This increase was
primarily attributable to the opening of the Company's eighth dental center in
October 1994.

     DENTISTS' SALARIES -- Dentists' salaries increased from $2.9 million for
the year ended December 31, 1994 to $3.3 million for the year ended December 31,
1995, an increase of $492,000 or 17.2%. The hiring of additional dentists to
staff the Company's eighth dental center and an increase in patient services
resulted in the increase in dentists' salaries. Expressed as a percentage of net
patient revenues, dentists' salaries increased from 16.7% to 18.3% for the years
ended December 31, 1994 and 1995, respectively.

     CLINICAL SALARIES -- Clinical salaries increased from $1.8 million for the
year ended December 31, 1994 to $1.9 million for the year ended December 31,
1995, an increase of $68,000 or 3.8%. The increase resulted from the addition of
the eighth dental center in October 1994. Expressed as a percentage of net
patient revenues, clinical salaries decreased from 10.6% to 10.3% for the years
ended December 31, 1994 and 1995, respectively, as a result of more efficient
scheduling and the increase in net patient revenues from the eighth dental
center.

     DENTAL SUPPLIES AND LABORATORY FEES -- Dental supplies and laboratory fees
increased from $1.9 million for the year ended December 31, 1994 to $2.2 million
for the year ended December 31, 1995, an increase of approximately $278,000 or
14.6%. The increased level of patient services and costs associated with the
opening of the Company's eighth center accounted for most of the increase.
Expressed as a percentage of net patient revenues, dental supplies and
laboratory expense increased from 11.2% to 12.0% for the years ended December
31, 1994 and 1995, respectively.

     RENTAL AND LEASE EXPENSE -- Rental and lease expense increased from
$681,000 for the year ended December 31, 1994 to $836,000 for the year ended
December 31, 1995, an increase of $155,000 or 22.8%. The increase resulted from
the opening of the eighth dental center in late 1994, the opening of the
Company's new corporate office in April 1995, and the moving of one of the
Company's dental centers to a larger facility, which resulted in a duplication
of lease payments at the old facility through the end of 1995.

                                       36
<PAGE>
Expressed as a percentage of net patient revenues, rental and lease expense
increased from 4.0% to 4.6% for the years ended December 31, 1994 and 1995,
respectively.

     ADVERTISING AND MARKETING -- Advertising and marketing expense decreased
from $1.1 million for the year ended December 31, 1994 to $959,000 for the year
ended December 31, 1995, a decrease of $103,000, or 9.7%. Reduced expenditures
for television advertising and the absence of direct mail costs incurred in
connection with opening of the eighth center in the fourth quarter of 1994
resulted in lower 1995 spending. Expressed as a percentage of net patient
revenues, advertising and marketing expense decreased from 6.2% to 5.3% for the
years ended December 31, 1994 and 1995 respectively.

     DEPRECIATION AND AMORTIZATION -- Depreciation and amortization expense
increased from $309,000 for the year ended December 31, 1994 to $336,000 for the
year ended December 31, 1995, an increase of 27,000 or 8.7%. Capital
expenditures incurred in the opening of the Company's eighth dental center in
the fourth quarter of 1994 and the moving of the corporate office to a new
location resulted in higher depreciation and amortization expense in 1995.

     OTHER OPERATING EXPENSES -- Other operating expenses increased from $2.2
million for the year ended December 31, 1994 to $2.3 million for the year ended
December 31, 1995, an increase of $55,000, or 2.5%. Expressed as a percentage of
net patient revenues, other operating expense decreased from 12.9% to 12.4% for
the years ended December 31, 1994 and 1995, respectively.

     GENERAL AND ADMINISTRATIVE -- General and administrative expense increased
from $5.3 million for the year ended December 31, 1994 to $9.1 million for the
year ended December 31, 1995, an increase of $3.8 million or 71.3%. The increase
resulted primarily from higher compensation paid to the Company's owners,
including $2.6 million under the Deferred Compensation Agreement entered into in
connection with the Reorganization. The Company also incurred higher costs
related to the corporate office opened in mid-1995 and higher administrative
personnel costs. Expressed as a percentage of net patient revenues, general and
administrative expense increased from 31.1% to 49.9% for the years ended
December 31, 1994 and 1995, respectively.

     INCOME TAXES -- In 1995 and 1994, significant operations of the Company
were conducted through a subchapter S corporation, which resulted in no
corporate income taxes being assessed against the profits of that company.
Subsequent to the Reorganization in December 1995, all of the Company's
operations became subject to corporate income taxes. The Company recognized a
benefit for income taxes of $325,000 in the year ended December 31, 1995,
reflecting primarily the charge for deferred compensation offset by a deferred
tax liability of $728,000 realized upon the loss of subchapter S status for
income tax purposes. This compared to a provision for income taxes of $43,000
for the prior year.

YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993

     NET PATIENT REVENUES -- Net patient revenues increased from $15.1 million
for the year ended December 31, 1993 to $17.1 million for the year ended
December 31, 1994, an increase of $2.0 million, or 13.5%. The addition of the
Company's sixth and seventh dental centers in May and August 1993, respectively,
and the opening of the eighth dental center in October 1994 accounted for the
increase in net patient revenues.

     DENTISTS' SALARIES -- Dentists' salaries increased from $2.7 million for
the year ended December 31, 1993 to $2.9 million for the year ended December 31,
1994, an increase of $169,000, or 6.3%. The opening of the new dental centers
accounted for most of the increase. Expressed as a percentage of net patient
revenues, however, dentists' salaries decreased from 17.8% to 16.7% for the
years ended December 31, 1993 and 1994, respectively, as the growth in net
patient revenues exceeded the increase in dentists' compensation.

     CLINICAL SALARIES -- Clinical salaries increased from $1.5 million for the
year ended December 31, 1993 to $1.8 million for the year ended December 31,
1994, an increase of $282,000, or 18.4%. Increased staffing necessary to open
new centers and higher personnel costs accounted for the increase. Expressed as
a percentage of net patient revenues, clinical salaries increased from 10.2% to
10.6% for the years ended December 31, 1993 and 1994, respectively.

                                       37
<PAGE>
     DENTAL SUPPLIES AND LABORATORY FEES -- Dental supplies and laboratory fees
increased from $1.6 million for the year ended December 31, 1993 to $1.9 million
for the year ended December 31, 1994, an increase of approximately $342,000 or
21.9%. The increased level of net patient revenues and costs associated with the
new dental centers opened in 1993 and 1994 accounted for the increase. Expressed
as a percentage of net patient revenues, dental supplies and laboratory fees
increased from 10.4% to 11.2% for the years ended December 31, 1993 and 1994,
respectively.

     RENTAL AND LEASE EXPENSE -- Rental and lease expense increased from
$504,000 for the year ended December 31, 1993 to $681,000 for the year ended
December 31, 1994, an increase of $177,000 or 35.1%. The increase resulted from
the opening of the new dental centers in 1993 and 1994. Expressed as a
percentage of net patient revenues, rental and lease expense increased from 3.3%
to 4.0% for the years ended December 31, 1993 and 1994, respectively.

     ADVERTISING AND MARKETING -- Advertising and marketing expense increased
from $729,000 for the year ended December 31, 1993 to $1,062,000 for the year
ended December 31, 1994, an increase of $333,000, or 45.7%. Production costs
associated with a new television advertising campaign and increased television
advertising frequency accounted for the increase. Expressed as a percentage of
net patient revenues, advertising and marketing expense increased from 4.8% to
6.2% for the years ended December 31, 1993 and 1994, respectively.

     DEPRECIATION AND AMORTIZATION -- Depreciation and amortization increased
from $245,000 for the year ended December 31, 1993 to $309,000 for the year
ended December 31, 1994, an increase of $64,000, or 26.1%. Capital expenditures
for leasehold improvements and dental equipment to open the Company's sixth,
seventh and eighth dental centers in 1993 and 1994 accounted for higher
depreciation expenses in 1994. Expressed as a percentage of net patient
revenues, depreciation and amortization increased from 1.6% to 1.8% for the
years ended December 31, 1993 and 1994, respectively.

     GENERAL AND ADMINISTRATIVE -- General and administrative expense increased
from $4.9 million for the year ended December 31, 1993 to $5.3 million for the
year ended December 31, 1994, an increase of $372,000 or 7.5%. The hiring of
additional personnel necessary to support the new dental centers added in 1993
and 1994 accounted for most of the increase. Expressed as a percentage of net
patient revenues, however, general and administrative expense decreased from
32.9% to 31.1% for the years ended December 31, 1993 and 1994, respectively, as
the growth in net patient revenues exceeded the increase in general and
administrative expense.

     INCOME TAXES -- In 1993 and 1994, significant operations of the Company
were conducted through a subchapter S corporation, which resulted in no
corporate income taxes being assessed against the profits of that company. As a
result, the provision for income taxes was approximately $40,000 in each year,
approximately $260,000 less than the provision would have been if all of the
Company's income had been subject to income taxes.

LIQUIDITY AND CAPITAL RESOURCES

     Prior to December 1995, the Company financed its operations and expansion
primarily through the use of internally generated funds, capital lease
obligations and bank borrowings. In December 1995, as part of the
Reorganization, the Company entered into the Securities Purchase Agreement with
the Pecks Investors and a Bank Credit Facility with NationsBank. A total of
$13.5 million was raised in these transactions, of which $6.0 million was used
to acquire the stock of Jack H. Castle, D.D.S., Inc. as part of the
Reorganization. The balance of the proceeds, net of expenses, was dedicated to
fund the Company's development and acquisition programs and to provide working
capital. As of June 30, 1996, the Company had available net working capital of
$816,000 which included $2.1 million in cash and cash equivalents.
   
     The Bank Credit Facility with NationsBank initially included a $6 million
term loan and a $3 million revolving line of credit. Principal payments of
$300,000 are payable quarterly, commencing June 15, 1996 through March 15, 2001.
On May 31, 1996, the Bank Credit Facility was amended and restated to increase
the term loan facility to $16.0 million. The additional $10 million advancing
term loan is to be utilized to fund acquisitions. Additional advances under the
term loan are repayable in quarterly installments commencing on September 15,
1996. The term loans bear interest at variable rates which are based upon (a)
either (i) NationsBank's base rate or (ii) LIBOR plus (b) a margin which varies
according to (1) the ratio of
    
                                       38
<PAGE>
   
the Company's funded debt to EBITDA, each as defined in the Bank Credit
Facility, (2) the type of loan (i.e. base rate or LIBOR loan) and (3) whether
the loan is a term loan, revolving credit loan or advancing term loan. As of
June 30, 1996, the Company had borrowed $3,950,000 of this facility to fund the
Florida and Tennessee acquisitions. In August 1996, the Company borrowed an
additional $2.1 million under the advancing term loan to fund the acquisition of
Horizon Dental Centers. The $3.0 million revolving line of credit is available
to be used for working capital requirements and acquisitions. It bears interest
at the same rate as the term loan and expires June 30, 1997. A commitment fee is
payable quarterly at rates ranging from 0.25% to 0.5% of the unused amounts for
such quarter. As of October 15, 1996, there was $1.8 million available under the
revolving line of credit. The Bank Credit Facility is collateralized by
substantially all of the Company's assets and is personally guaranteed by Jack
H. Castle, Jr. The Company intends to repay approximately $6.2 million of the
advancing term loan from the proceeds of this offering, and will have
approximately $5.4 million remaining outstanding under the term loan.
    
     On December 19, 1995, the Company issued $7.5 million in Senior
Subordinated Notes to the Pecks Investors. Interest is payable quarterly in
arrears with principal payable in two installments of $3.75 million each on
December 18, 2001 and 2002. In conjunction with the placement of the Senior
Subordinated Notes, the Company issued 1,244,737 shares of Series A Convertible
Preferred Stock to the Pecks Investors. The Series A Convertible Preferred Stock
is mandatorily redeemable at the holders' option upon a change of control in the
Company's ownership, or after December 18, 2001, if no secondary market exists
for the Series A Convertible Preferred Stock. The Series A Convertible Preferred
Stock is convertible into 1,244,737 shares of Common Stock, subject to
antidilution adjustments. The holders of Series A Convertible Preferred Stock
have advised the Company that they intend to convert the Series A Convertible
Preferred Stock into Common Stock, simultaneously with, and conditioned on, the
completion of this offering. The value of the Series A Convertible Preferred
Stock, $3.1 million, has been recorded as a discount to the Senior Subordinated
Notes and is being amortized over the life of the Senior Subordinated Notes.
Upon repayment of the Senior Subordinated Notes and conversion of the Series A
Convertible Preferred Stock at the closing of this offering, the Company will
recognize an extraordinary loss of $1.9 million on the retirement of the Senior
Subordinated Notes, net of income tax effect of $1.2 million.

     The Bank Credit Facility and the Securities Purchase Agreement contain
affirmative and negative covenants that require the Company to maintain certain
financial ratios, limit the amount of additional indebtedness, limit the
creation or existence of liens and set certain restrictions on acquisitions,
mergers and sales of assets. The covenants in the Securities Purchase Agreement
expire on the repayment of the Senior Subordinated Notes.
   
     In the aggregate, for the Completed Acquisitions, the Company paid
consideration consisting of $9.3 million in cash, $4.5 million in Seller Notes
and 433,163 shares of Common Stock. An aggregate of $943,363 of the Seller Notes
is convertible into Common Stock at a conversion price of $6.75 per share,
subject to antidilution adjustments and automatic annual increase in conversion
price. The Company also assumed debt of approximately $600,000 consisting mostly
of capital lease obligations. The cash portion of the Pending Acquisitions will
be funded with the proceeds of this offering and will consist of approximately
$27.3 million. The Company will also assume long-term debt obligations of
$736,000 in connection with the Arkansas Acquisition and the Austin Acquisition.
    
     The Company intends to acquire the assets of additional dental practices
and to fund this growth, in part, with existing cash, cash flow from operations,
proceeds from this offering, seller financing and borrowings under the Bank
Credit Facility. The Company is presently negotiating with NationsBank to
increase the total amount available under the Bank Credit Facility to $25
million following completion of this offering, which would result in the Company
having borrowing availability of approximately $19.6 million. The Company
believes it will be able to fund its acquisition, expansion and working capital
needs for the next 18 months through use of its existing cash resources, cash
flow from operations, proceeds from this offering and the Bank Credit Facility.
Thereafter, the Company may raise capital through the issuance of additional
debt or the issuance of securities in public or private transactions to fund
future expansions. There can be no assurance that NationsBank will agree to
increase the amount available under the Bank Credit Facility or that acceptable
financing for future acquisitions or expansion of existing dental networks can
be obtained. See "Unaudited Pro Forma Combined Financial Information" for
additional information concerning the effects on the financial condition of the
Company of the net proceeds of this offering.

                                    BUSINESS

OVERVIEW
   
     The Company develops and operates integrated dental networks through
affiliations with general, orthodontic and multi-specialty dental practices in
the United States. The Company currently conducts operations in the states of
Texas, Florida and Tennessee and has entered into definitive agreements to
acquire certain assets of and manage dental practices headquartered in Long
Island, New York, serving the New York metropolitan area, and Little Rock,
Arkansas, with offices in Arkansas, Oklahoma and Louisiana, and a letter of
intent to acquire certain assets of and manage a dental practice located in
Austin, Texas which the Company believes will complement its existing operations
in Austin, Texas. The Company establishes integrated dental networks through
affiliations with dental practices providing quality care in selected markets
across the United States with a view to achieving broad geographic coverage
within those markets. The Company seeks to achieve operating efficiencies by
consolidating and integrating affiliated practices into regional networks,
realizing economies of scale in such areas as marketing, administration and
purchasing and enhancing the revenues of its affiliated dental practices by
increasing both patient visits and the range of specialty services offered. As
of October 15, 1996, the Company provided management services to 35 dental
centers with approximately 85 affiliated dentists, orthodontists and other
dental specialists. Upon consummation of the Pending Acquisitions, the Company
will manage 60 dental centers with approximately 225 affiliated dentists,
orthodontists and other dental specialists.

     The Company was formed in 1981 by Jack H. Castle, D.D.S. and Jack H.
Castle, Jr., as a single location, multi-specialty dental practice in Houston,
Texas. From 1982 through October 15, 1996, the Company expanded to a total of
nine locations with 35 dentists in the Houston metropolitan area. During this
period the Company developed, implemented and refined the integrated dental
network approach which it intends to utilize as a basis for its national
expansion.
    
     The Company's objective is to make each of its dental networks the leading
group dental care provider in each market it serves. Since its formation, the
Company has applied traditional retail principles of business and marketing
techniques to the practice of dentistry, including locating practices in
high-profile locations, offering more affordable fees and payment plans,
expanding the range of services offered, increasing market share through
aggressive advertising and offering extended office hours. By using the Castle
Dental Centers' approach to managing affiliated dental practices, the Company
believes it will enable affiliated dentists, orthodontists and other dental
specialists to focus on delivering quality patient care and to realize
significantly greater productivity than traditional individual and small-group
dental practices.

     The Company believes that the provision of a full range of dental services
through an integrated network is attractive to managed care payors and intends
to continue to pursue managed care contracts. The Company currently maintains an
aggregate of ten capitated contracts and preferred provider arrangements
covering approximately 21,000 members and, upon consummation of the New York
Acquisition, the Company will have an aggregate of 60 capitated contracts and
preferred provider arrangements covering approximately 58,000 members. The
Company believes that the continued development of its networks will assist it
in negotiating national and regional capitated arrangements with managed care
payors or other arrangements.

     The Company intends to utilize the practice management principles employed
in its Houston operations to establish a consistent national identity for its
business. Moreover, the Company believes that its experience and expertise in
managing multi-specialty dental group practices, as well as the development of
name recognition associated with the name "Castle Dental Centers," will
provide its affiliated dental practices with a competitive advantage in
attracting and retaining patients and realizing practice efficiencies.

     There presently are nine Castle Dental Centers operating in the Houston,
Texas area and four additional centers in Houston in various stages of
development. In May 1996, the Company acquired the assets of and entered into
long-term management agreements with 1st Dental Care, P.A., a dental practice
with 12 locations in the Tampa/Clearwater, Florida area, and Mid-South Dental
Centers, P.C., a dental

                                       40
<PAGE>
practice with six dental centers in various locations in Tennessee. In August
1996, the Company increased its dental practices under management in Texas by
acquiring the assets of Horizon Dental Centers, a dental practice with four
dental centers in Fort Worth, Texas and four dental centers in Austin, Texas.
   
     The Company has entered into definitive agreements to acquire certain
assets of and enter into long-term management agreements with American Dental
Centers, a dental practice based in Long Island, New York with 12 dental centers
in the New York metropolitan area, and United DentalCare, a dental practice
based in Little Rock, Arkansas that operates nine dental centers in Arkansas,
Oklahoma and Louisiana, and a letter of intent to acquire certain assets of and
enter into a long-term management agreement with Southwest Dental Associates, a
dental practice based in Austin, Texas that operates four dental centers in the
Austin, Texas metropolitan area. The New York Acquisition is expected to close
contemporaneously with, and is mutually conditioned on, the closing of this
offering, and the Arkansas Acquisition and the Austin Acquisition are expected
to close within 30 days of the closing of this offering.
    
INDUSTRY BACKGROUND
   
     Dental care services in the United States are generally delivered through a
fragmented system of local providers, primarily sole practitioners, or small
groups of dentists, orthodontists or other dental specialists, practicing at a
single location with a limited number of professional assistants and business
office personnel. According to the American Dental Association 1995 Survey of
Dental Practice ("ADA Survey"), there were approximately 150,800 actively
practicing dental professionals in the U.S., of which approximately 8,900 were
practicing orthodontists. Nearly 81% of the nation's private practitioners work
either as sole practitioners or in a practice with one other dentist. The
balance of these dentists practice in about 4,700 groups of three or more
dentists. However, dental, orthodontic and other specialty practices have
followed the trend of the health care industry generally and are increasingly
forming larger group practices.
    
     The annual aggregate domestic market for dental services is estimated to be
approximately $46.5 billion for 1995, representing approximately 4.2% of total
health care expenditures in the United States, and is projected to reach $79.1
billion by 2005. Within the total market for dental services in the United
States, there are, in addition to general dentistry, a number of specialties,
including orthodontics (the straightening of teeth and remedy of occlusion),
periodontics (gum care), endodontics (root canal therapy), oral surgery (tooth
extraction) and pedodontics (care of children's teeth). The dental services
market has grown at a compound annual growth rate of approximately 8.0% from
1980 to 1995, and is projected to grow at a compound annual growth rate of
approximately 6.0% through the year 2005. In contrast to other health care
expenditures, dental services are primarily paid for by the patient. According
to the U.S. Department of Health and Human Services, in 1995, consumer
out-of-pocket expenditures accounted for 53% of the payment for dental services,
compared to 19% for other medical services.

     The Company believes that the growth in the dental industry has largely
been driven by four factors: (i) an increase in the availability and types of
dental insurance; (ii) an increasing demand for dental services from an aging
population; (iii) the evolution of technology which makes dental care less
traumatic; and (iv) an increased focus on preventive and cosmetic dentistry.

     Concerns over the accelerating cost of health care have resulted in the
increasing importance of managed care in the dental industry. Managed care
typically involves a third party (frequently the payor) assuming responsibility
for ensuring that health care is provided in a high-quality, cost-effective
manner. According to industry sources, approximately 18.6% of the estimated
118.5 million people covered by dental benefits in 1995 was enrolled in managed
care programs. It is estimated that managed care's penetration of this group
will increase to 35% of the 131 million people expected to be covered by dental
benefits in the year 2000. Enrollment in managed dental care plans, according to
the National Association of Dental Plans, is estimated to have grown from 7.8
million patients in 1990 to 22.8 million patients in 1995.

     The Company believes that the provision of dental, orthodontic and other
specialty care will follow the pattern set by other segments of the health care
industry, moving away from the sole practitioner model to a

                                       41
<PAGE>
group practice environment in which a separate professional management team
handles personnel, management, billing, marketing and other business functions.
The trends which are leading dentists to affiliate with dental practice
management companies include: (i) the increasingly capital intensive nature of
acquiring and maintaining state-of-the-art dental equipment, laboratory and
clinical facilities; (ii) the growing need to develop and maintain specialized
management information and billing systems to meet the increasing demands of
payors; and (iii) the increasingly more complicated, competitive and regulated
business environment for dentists.

BUSINESS STRATEGY

     The Company's strategy is to develop integrated networks for the provision
of dental services through practice affiliations that provide quality,
cost-effective dental care in target markets. Key elements of this strategy are
to:

        PROVIDE HIGH-QUALITY, COMPREHENSIVE, ONE-STOP FAMILY DENTAL HEALTH
        CARE.  The prototypical Castle Dental Center provides general dentistry
        as well as a full range of dental specialities (including orthodontics,
        pedodontics, periodontics, endodontics, oral surgery and implantology),
        thereby allowing the majority of specialty referrals to remain in-house
        within the Company's network of facilities. By bringing together
        multi-specialty dental services within a single practice, the Company is
        able to realize operating efficiencies and economies of scale and to
        promote increased productivity, higher utilization of professionals and
        facilities, and the sharing of dental specialists among multiple
        locations. The Company's practice model also incorporates quality
        assurance and quality control programs, including the establishment of
        committees and policy boards to oversee the clinical aspects of the
        provision of dental services, peer review and continuing education and
        technique enhancement. The Company believes that its multi-specialty
        strategy significantly differentiates it from both individual and
        multi-center practices that typically offer only general dentistry,
        orthodontics or other single specialty dental services.

        DEVELOP COMPREHENSIVE DENTAL NETWORKS IN TARGET MARKETS.  The Company
        intends to build its networks through acquisition of existing practices
        and DE NOVO development of additional practices within target markets.
        The Company seeks to consolidate and integrate its affiliated practices
        to establish regional dental care networks. The Company believes this
        network system will enable it to reduce the operating costs of its
        affiliated practices by centralizing certain functions such as
        telemarketing and advertising, billing and collections, payroll and
        accounting and by negotiating regional and national contracts for
        supplies, equipment, services and insurance. Once practice affiliations
        are established in a market, the Company seeks to assist the affiliated
        practices in expanding its range of services to make available specialty
        dental services not previously offered.
   
        APPLY TRADITIONAL RETAIL PRINCIPLES OF BUSINESS TO DENTAL CARE.  The
        Company believes it can enhance revenues and profitability by applying
        traditional retail principles of business to the provision of dental
        services in its target markets. These principles include professionally
        produced broadcast and print advertisements targeting specific
        audiences, and extended hours of operation which are convenient for
        patients, including weekend and evening hours. As part of its retail-
        oriented strategy, the Company will seek to establish or, where
        appropriate, relocate each Castle Dental Center in a convenient location
        in or near a high-profile neighborhood retail area and utilize
        innovative sales and marketing programs designed to achieve strong name
        recognition and increase patient visits. In addition, the Company
        stresses the breadth and affordability of its services and works closely
        with patients to establish treatment schedules and affordable payment
        plans tailored to the patients' needs.
    
        MARKET ITS NETWORKS TO MANAGED CARE ENTITIES.  The Company believes that
        managed care will play an increasing role in the provision of dental
        services and therefore intends to market the services of its dental
        practice networks to the managed care community. The Company believes
        that contracting with managed care entities will facilitate entry into
        new markets and the

                                       42
<PAGE>
        expansion of existing networks by providing a source of patients to
        dentists with whom the Company is seeking to affiliate. In addition,
        such contracts, including capitated contracts, enable the Company to
        leverage its infrastructure and marketing efforts by increasing patient
        visits.

DENTAL NETWORK DEVELOPMENT

     The Company seeks to build its dental networks through acquisition of
existing dental practices and the DE NOVO development of dental practices in
high-profile retail environments.

ACQUISITION CRITERIA

     The Company's acquisition strategy is to identify successful group dental
practices in its target markets, acquire certain assets of the identified
practices, enter into long-term management services agreements, and utilize
these core practices as a base from which to expand within the target markets.
Prior to entering any market, the Company considers such factors as population,
demographics, market potential, competitive environment, supply of available
dentists, dental regulatory environment, patient-provider ratios, advertising
costs and the economic condition of the local market. Core acquisition
candidates are successful group dental practices that the Company believes are
leaders in their regional markets. Subsequent acquisitions target practices that
strategically complement the core practices within a market. In considering
acquisitions, the Company evaluates qualitative issues such as the dental
professionals' qualifications, experience and reputation in the local
marketplace and their operating histories, as well as the ability to demonstrate
potential for revenue growth and continued profitability. The Company has
identified a substantial number of individual and group dental practices that
meet its acquisition criteria.

     The New York Acquisition will close contemporaneously with and is mutually
conditioned on the closing of this offering. American Dental Centers has offices
throughout the New York metropolitan area and is a party to an aggregate of over
50 capitated contracts and preferred provider arrangements which account for
over 70% of its total revenues. The purchase price for the New York Acquisition
is $20.0 million in cash and $5.0 million in Common Stock valued at the initial
public offering price. On the consummation of the Company's acquisition of
American Dental Centers, Jules V. Lane D.D.S., the founder of American Dental
Centers, will join the Company's Board of Directors and will enter into a three-
year employment agreement with the Company pursuant to which Dr. Lane will
remain active in the management of and strategic planning for American Dental
Centers.

     Dr. Lane is also the owner of AMLI which markets preferred provider
programs, of which American Dental Centers is a significant provider. At the
closing of the New York Acquisition, the Company will enter into certain
contractual arrangements with AMLI which will provide that in markets in the
State of New York served by the dental practices managed by the Company (i) AMLI
and the Company will each include information regarding the programs and
services of the other in their respective marketing materials, (ii) AMLI will
maintain preferred provider relationships with dental practices managed by the
Company and offer such dental practices as preferred providers to AMLI
policyholders and other covered parties and (iii) AMLI and the Company will
share certain facilities and personnel. Each party has a right of first refusal
to extend such arrangements to states other than New York.

     The Company has entered into a definitive agreement with respect to the
Arkansas Acquisition and a letter of intent with respect to the Austin
Acquisition. Both the Arkansas Acquisition and the Austin Acquisition are
expected to close within 30 days of the closing of this offering but neither is
a condition to the closing of this offering. The purchase price for the Arkansas
Acquisition is $2.6 million in cash and 185,000 shares of Common Stock and the
purchase price for the Austin Acquisition is $4.8 million in cash and $1.6
million in Common Stock, valued at the initial public offering price. In each of
the Arkansas Acquisition and the Austin Acquisition, additional cash
consideration will be paid if the acquired practice achieves specified operating
results subsequent to the completion of the transaction.

     The contractual arrangements pursuant to which the Pending Acquisitions
will be made include representations and warranties from the sellers regarding
the assets being acquired and employment or consulting agreements containing
noncompetition provisions with the former owners of such practices. The Common
Stock to be issued in the Pending Acquisitions will have certain contractual
registration rights which may be exercised in future offerings of Common Stock
by the Company. See "Description of Capital Stock -- Registration Rights."
    
AFFILIATION AND INTEGRATION OF DENTAL CENTERS

     In affiliating with dental practices, the Company typically: (i) acquires
certain assets of the practice, and, in certain situations, laboratory or other
ancillary facilities that are either owned by or affiliated with such practice;
(ii) enters into a long-term management services agreement with such dental
practice pursuant to which the Company provides comprehensive management
services to the affiliated practice; (iii)

                                       44
<PAGE>
requires that the affiliated dentists enter into employment agreements
containing non-compete and liquidated damages provisions; and (iv) assumes the
principal administrative, financial, marketing and general management functions
of the affiliated practice, including employment of most administrative
personnel. As soon as practicable following the acquisition of an affiliated
dental practice, when market conditions permit, the Company initiates the
process of converting the affiliated practice into a Castle Dental Center. This
process, the implementation and timing of which will vary from market to market,
typically includes the addition of specialty dental services not previously
offered by the center, implementation of retail business concepts applied by the
Company in its Houston operation, and, where appropriate, the relocation of the
center to a more desirable location.

     In certain markets, the Company intends to grow through DE NOVO development
to expand in market areas that are either under-served or are otherwise
attractive market opportunities and in which there is no suitable acquisition
candidate. The Company will use its experience in building and staffing DE NOVO
dental centers in Houston, Texas for the implementation of this expansion
strategy.

MANAGEMENT SERVICES AGREEMENT

     The Company has entered into a Management Services Agreement with each of
its affiliated dental practices pursuant to which the Company becomes the
exclusive manager and administrator of all non-dental services relating to the
operation of the practice. As compensation for its services under the typical
Management Services Agreement and subject to applicable law, the Company is
reimbursed for the expenses incurred by it on behalf of the managed practices
and is paid a monthly management fee. The Company anticipates that it will enter
into similar Management Services Agreements with each new affiliated dental
practice.
   
     The amount of the management fee charged by the Company to an affiliated
dental practice is intended to reflect and is based on the fair value of the
management services rendered by the Company to the affiliated dental practice.
Typically, the Management Services Agreements provide for a management fee based
on either a percentage of the adjusted gross revenues of the affiliated dental
practice, or on a cost-plus calculation based on the cost of the services
performed by the Company on behalf of the affiliated dental practice. In
addition, in some instances the Company will receive a performance fee, based on
criteria agreed to by the Company and the affiliated dental practice. The amount
of the management fee is reviewed by the Company and the affiliated dental
practice not less frequently than annually in order to determine whether such
fee should be adjusted, up or down, to continue to reflect the fair value of the
management services rendered by the Company.

     The obligations of the Company under the typical Management Services
Agreement include assuming financial and other responsibility, either on its own
or with the input and participation of the policy board of the affiliated
practice, for the following (subject to limitations imposed by applicable state
law): facilities, equipment and supplies; advertising, marketing and sales;
training and development; operations management; provision of support services;
risk management and utilization review; application and maintenance of
applicable local licenses and permits; negotiation of contracts between the
affiliated dental practice and third parties, including third-party payors,
alternative delivery systems and purchasers of group health care services;
establishing and maintaining billing and collection policies and procedures;
fiscal matters, such as annual budgeting, maintaining financial and accounting
records, and arranging for the preparation of tax returns; and maintaining
insurance. The Company does not assume any authority, responsibility,
supervision or control over the provision of dental services to patients or for
diagnosis, treatment, procedure or other health care services, or the
administration of any drugs used in connection with any dental practice.
    
     The typical Management Services Agreement is for an initial term of 40
years, and is automatically renewed for successive five-year terms unless
terminated at least 90 days before the end of the initial term or any renewal
term. Additionally, the typical Management Services Agreement may be terminated
by the Company or the affiliated dental practice in the event of the bankruptcy
or default in the performance of the material duties of the nonterminating
party.

                                       45
<PAGE>
DENTIST EMPLOYMENT AGREEMENTS
   
     As a part of the process of converting an affiliated dental practice into a
Castle Dental Center, each affiliated dental practice has entered into a Dentist
Employment Agreement with each of its full-time dentists, orthodontists and
other dental specialists. The Company anticipates that this practice will
continue when market conditions permit. Although the form of contract varies
somewhat among practices and among dentists with different specialties, the
typical contract for a full-time dentist provides for a defined compensation
arrangement, including performance-based compensation and, where market
conditions and appplicable law permit, a covenant not to compete. Each full-time
dentist, whether or not a party to a Dentist Employment Agreement, is required
to maintain professional liability insurance, and mandated coverage limits are
generally at least $1.0 million per claim and $1.0 million in aggregate. In
addition, many affiliated dental practices employ part-time dentists. Not all
part-time dentists have employment agreements, but all part-time dentists are
required to carry professional liability insurance in specified amounts. Certain
full- and part-time dentists retained by the Company, particularly in the New
York market, are independent contractors and have entered into independent
contractor agreements.
    
OPERATIONS

CENTER DESIGN AND LOCATION

     The affiliated dental practices are generally located in retail
environments. Many of the affiliated practices include semi-private general
dentistry treatment rooms, private treatment rooms and orthodontic bays.
Currently, affiliated dental practices include up to 21 treatment rooms and
range in size from approximately 2,000 square feet to approximately 6,000 square
feet.

     Where an acquired practice is not able, due to limitations of floor space,
zoning or other reasons, to accommodate new services or specialists, the Company
seeks to relocate such affiliated practice to a high profile retail location as
soon as practicable. Since its formation, the Company has adapted its locations
in Houston, Texas to accommodate the full range of dental specialities. The
Company believes the application of its method of designing and locating dental
centers will facilitate the expansion of services offered by the acquired
practices.

STAFFING AND SCHEDULING

     The Company believes that making its facilities available at times which
are convenient to its patients is an important element of its strategy. As a
result, the affiliated dental practices maintain extended hours of operation,
with many affiliated practices opening as early as 7:00 a.m. and closing as late
as 9:00 p.m. on weekdays and 5:00 p.m. on Saturdays. The affiliated practices
are staffed with dentists and dental assistants every day they are open, with
orthodontists and other specialists rotating among two or three centers in order
to utilize their time optimally. Each patient typically sees the same dentist or
specialist on all visits to the center. Each affiliated dental practice is also
regularly staffed with an office manager, front office staff, dental assistants
and other support staff.

     The Houston dental centers are, and the prototypical dental centers, where
appropriate, will be staffed with treatment counselors who are responsible for
the non-clinical aspects of the patient's relationship with the practice. The
treatment counselor's function is (i) to put the patient at ease by acting as a
liaison between the dentist and patient and working with the patient to develop
a treatment schedule with payments tailored to the patient's needs within the
Company's established credit policies; and (ii) to maximize the dentist's time
spent with patients.

FEES AND PAYMENT PLANS

     The Company believes that fees charged by its affiliated practices are
typically lower than usual and customary fees within their respective markets.
The affiliated practices generally provide a wide range of payment options,
including cash, checks, credit cards, third party insurance and various forms of
credit. In general, most general dentistry and specialty services, other than
orthodontics, are paid for by the patient, or billed to the patient's insurance
carrier, on the date the service is rendered. In some instances, the Company

                                       46
<PAGE>
will extend credit in accordance with its established credit policies. The
Company believes that its lower fees and ability to assist patients in obtaining
financing provides it with a competitive advantage compared to sole
practitioners and small group practices.

     The Company's typical orthodontic payment plan consists of no initial down
payment and equal monthly payments during the term of treatment of approximately
$89 per month. After consultation with the treatment counselor at the initial
visit, the patient signs a contract outlining the terms of the treatment,
including the anticipated length of treatment and the total fees. The number of
required monthly payments is fixed at the beginning of the case and corresponds
to the anticipated number of monthly treatments. Patients are billed in advance
by the Company on a monthly basis.

SALES AND MARKETING

     The Company intends to utilize the practice management principles employed
in its Houston operations to establish a consistent national identity for its
business and to utilize the "Castle Dental Centers" name and logo. When
acquired practices already have high existing name recognition within their
local markets, the Company may seek to capitalize on it and implement the Castle
model while maintaining the existing practice name. The Company applies
traditional retail principles of business to the provision of dental care. These
principles include network development, extended hours of operation, location
optimization, signage, customized treatment schedules, affordable fees and
payment plans. The Company has used both print advertising and professionally
produced broadcast advertising. It maintains a significant advertising budget
and aggressively markets the name "Castle Dental Centers" and the services it
offers to potential patients in Houston, Texas. The Company intends to use the
same aggressive marketing in its regional markets.

     The Company has also established a regional telemarketing system in
Houston, Texas to field calls generated by advertising, to confirm upcoming
scheduled patient visits, to encourage patients to return for follow-up visits
and regularly scheduled six-month periodic exams. Where feasible, the Company
intends to establish additional telemarketing systems in other regional markets.
The telemarketers can enter all relevant information into the Company's
management information system for patients making appointments for an initial
visit, including pre-screening patients for insurance and other credit
information.

QUALITY ASSURANCE

     Affiliated dental practices are solely responsible for all aspects of the
practice of dentistry. The Company has responsibility for the business and
administrative aspects of the practices and exercises no control over the
provision of dental services. To facilitate the execution of these separate
responsibilities and the communication between the Company and its affiliated
dental practices, the Company has established a National Operations Management
Committee, a National Dental Service Management Committee and generally
establishes policy boards in each market it enters. The respective committees
are the primary vehicles through which the Company and its affiliated dental
practices communicate, develop long-term strategic objectives and make
recommendations regarding significant capital expenditures, budgets and
acquisitions.

     The Company's management structure is designed to bring to its affiliated
dental practices improvements in their recruiting and professional training. The
Company expects that the increased visibility of the Company, its national
presence, the ability to offer career paths previously unavailable to dentists
and the ability to recruit for multiple markets on a national level will give it
an advantage in recruiting and retaining dentists. In addition, the Company
believes that the ability to offer dentists in private practice the chance to
practice in an environment where they do not assume capital risks and
administrative burdens normally associated with private practice will make
joining the Company an attractive choice for private practitioners desiring to
simplify their professional lives.

     The Company has named one of its most experienced affiliated dentists as
National Dental Director. This person will be responsible for the monitoring and
improvement of quality standards, the peer review process and the development of
a common materials guideline. In addition, the National Dental Director

                                       47
<PAGE>
will coordinate development of relations with dental schools and the development
of a cross-practice training program for enhancing techniques used in the
practice of dentistry.

     The Company assists affiliated dental practices in their efforts to improve
the delivery of quality dental care. The National Dental Service Management
Committee, which is comprised of the Company's leading affiliated dentists, has
been formed to identify and communicate to affiliated dentists the best
practices and protocols in dental practice areas, oversee peer review, materials
selection, continuing education, technique enhancement and specialty care.

     Most affiliated dental practices have policy boards comprised of
representatives of both the Company and the affiliated dental practice. The
policy boards are responsible for developing and implementing management and
administrative policies for the overall operation of the affiliated dental
practice. Specifically, the policy board has the authority to review and approve
capital improvements and expansion, marketing and advertising, collection
policies, provider and payor relationships, strategic planning and capital
expenditures. However, in recognition of the laws and regulations applicable to
the licensure and practice of dentistry, the policy board does not make clinical
decisions, recommendations or other decisions that are required to be made by a
licensed dentist.

MANAGED CARE

     Concerns over the accelerating cost of dental care have resulted in the
increasing role of managed care in the Company's strategy. As markets evolve
from traditional fee-for-service dental care to managed care, dental care
providers confront competitive pressure to provide high-quality dental care in a
cost-effective manner. Employer groups have begun to bargain collectively in an
effort to reduce the cost of dental care and to bring about greater
accountability of providers with respect to accessibility, choice of provider,
quality of care and other indicators of consumer satisfaction.
   
     The Company believes that managed care will play an increasing role in the
provision of dental services and therefore intends to market the services of its
networks to the managed care community. A component of the Company's strategy is
to seek long-term relationships with insurance companies with a view to reducing
the Company's risk of expanding into new markets served by the insurance
companies, and permits the Company to leverage its growth by including patients
covered by managed care contracts. Moreover, the Company believes that its
managed care relationships will enhance the Company's utilization rates at
existing locations. While the laws of some states permit the Company to
participate in the negotiation by affiliated dental practices of managed care
contracts, preferred provider arrangements and other negotiated price
agreements, the affiliated dental practices are the contracting parties for all
such relationships, and the Company is dependent on its affiliated dental
practices for the success of such relationships. See "Risk Factors -- Risks
Associated with Managed Care Contracts; Capitated Fee Revenue" and
"-- Reliance on Affiliated Dental Practices."
    
SERVICES

     The Company provides management expertise, marketing, information systems,
capital resources and acquisition services to its affiliated dental practices.
As a result, the Company is involved in the financial and administrative
management of the affiliated dental practices, including legal, financial
reporting, cash management, human resources and insurance assistance. The
Company's goals in providing such services are (i) to allow the dentists
associated with affiliated dental practices to dedicate their time and efforts
more fully to patient care and professional practice activities; (ii) to improve
the performance of affiliated dental practices in these administrative and sales
activities; and (iii) to enhance the financial return to the Company.

     Aside from the centralization of functions mentioned above, the affiliated
dental practices are encouraged to administer their practices in accordance with
the needs of their specific patient populations. The practice of dentistry at
each affiliated dental practice is under the exclusive control of the dentists
who practice at such location.

                                       48
<PAGE>
     The majority of the practices whose non-dental assets are available to the
Company for acquisition are general dentistry practices. General dentistry
includes diagnostics, treatment planning, preventive care, removal of infection,
fillings, crowns, bridges, partials, dentures, and extractions, all of which are
currently being provided by the affiliated dental practices. Within its network,
the Company provides a wide range of specialty services. The Company seeks to
expand the services offered by affiliated practices beyond general dentistry to
include other dental specialty services and improve efficiency by improving
appointment availability, increasing practice visibility and assisting the
practices in adding complementary services. These complementary services include
orthodontics, periodontics (the diagnosis, treatment and prevention of infection
of the gums and supporting bone around the teeth), endodontics (the diagnosis,
treatment and prevention of infection of the oral tissues), oral surgery and
implantology (the placement of abutments (implants) in the jaw bones to support
tooth replacement). By adding these complementary services to the practice, the
affiliated dental practices will retain the majority of specialty service
referrals in-house, thereby increasing patient revenues.

MANAGEMENT INFORMATION SYSTEMS

     The Company and its affiliated dental practices presently utilize various
dental practice management software systems to monitor and control patient
treatment, scheduling, invoicing of patients and insurance companies,
productivity of clinical staffs and other practice related activities. The
Company has identified the practice management software system that it currently
employs in its Houston operations as its preferred system and intends, where
appropriate, to use the Houston system as a common practice management system
for use by its affiliated practices. The Company is presently implementing a
client-server based information management system designed to enable the Company
to compare financial performance of affiliated dental practices, to track and
control costs, and to facilitate the accounting and financial reporting process
between the affiliated dental practices and corporate headquarters. The Company
intends to use its financial information system in conjunction with existing
practice management systems at the affiliated dental practices.

GOVERNMENT REGULATION

     GENERAL

     The practice of dentistry is highly regulated, and there can be no
assurance that the regulatory environment in which the affiliated dental
practices and the Company operate will not change significantly in the future.
In general, regulation of health care related companies also is increasing.

     Every state imposes licensing and other requirements on individual dentists
and dental facilities and services. In addition, federal and state laws regulate
health maintenance organizations and other managed care organizations for which
dentists may be providers. In connection with its operations in existing markets
and expansion into new markets, the Company may become subject to compliance
with additional laws, regulations and interpretations or enforcements thereof.
The ability of the Company to operate profitably will depend in part upon the
Company and its affiliated dental practices obtaining and maintaining all
necessary licenses, certifications and other approvals and operating in
compliance with applicable health care regulations.

     Dental practices must meet federal, state and local regulatory standards in
the areas of safety and health. Historically, those standards have not had any
material adverse effect on the operations of the dental practices managed by the
Company. Based on its familiarity with the operations of the dental practices
managed by the Company, management believes that it and the practices it manages
are in compliance in all material respects with all applicable federal, state
and local laws and regulations relating to safety and health.

     MEDICARE AND MEDICAID FRAUD AND ABUSE

     Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for, or in order to induce, (i) the referral of a
person for services, (ii) the furnishing or arranging for the furnishing of
items or services or (iii) the purchase, lease or order or arranging or
recommending

                                       49
<PAGE>
purchasing, leasing or ordering of any item or service, in each case,
reimbursable under Medicare or Medicaid. Because dental services are covered
under various government programs, including Medicaid, the law applies to
dentists and the provision of dental services. Pursuant to this anti-kickback
law, the federal government announced a policy of increased scrutiny of joint
ventures and other transactions among health care providers in an effort to
reduce potential fraud and abuse related to Medicare and Medicaid costs. Many
states have similar anti-kickback laws, and in many cases these laws apply to
all types of patients, not just Medicare and Medicaid beneficiaries. The
applicability of these federal and state laws to many business transactions in
the health care industry, including those intended by the Company, has not yet
been subject to judicial interpretation.

     Significant prohibitions against physician self-referrals, including those
by dentists, for services covered by Medicare and Medicaid programs were
enacted, subject to certain exceptions, by Congress in the Omnibus Budget
Reconciliation Act of 1993. These prohibitions, commonly known as "Stark II,"
amended prior physician and dentist self-referral legislation known as "Stark
I" (which applied only to clinical laboratory referrals) by dramatically
enlarging the list of services and investment interests to which the referral
prohibitions apply. Effective January 1, 1995 and subject to certain exceptions,
Stark II prohibits a physician or dentist or a member of his immediate family
from referring Medicare or Medicaid patients to any entity providing
"designated health services" in which the physician or dentist has an
ownership or investment interest, or with which the physician or dentist has
entered into a compensation arrangement, including the physician's or dentist's
own group practice unless such practice satisfies the "group practice"
exception. The designated health services include the provision of clinical
laboratory services, radiology and other diagnostic services (including
ultrasound services), radiation therapy services, physical and occupational
therapy services, durable medical equipment, parenteral and enteral nutrients,
certain equipment and supplies, prosthetics, orthotics, outpatient prescription
drugs, home health services and inpatient and outpatient hospital services. A
number of states also have laws that prohibit referrals for certain services
such as x-rays by dentists if the dentist has certain enumerated financial
relationships with the entity receiving the referral, unless an exception
applies.

     Noncompliance with, or violation of, the federal anti-kickback legislation
or Stark II can result in exclusion for Medicare and Medicaid programs and civil
and criminal penalties. Similar penalties are provided for violation of state
anti-kickback and self-referral laws. To the extent that the Company or any
affiliated dental practice is deemed to be subject to these federal or similar
state laws, the Company believes its intended activities will comply in all
material respects with such statutes and regulations.

     STATE LEGISLATION
   
     In addition to the anti-kickback laws and anti-referral laws noted above,
the laws of many states prohibit dentists from splitting fees with non-dentists
and prohibit non-dental entities such as the Company from engaging in the
practice of dentistry and from employing dentists to practice dentistry. The
specific restrictions against the corporate practice of dentistry, as well as
the interpretation of those restrictions by state regulatory authorities, vary
from state to state. However, the restrictions are generally designed to
prohibit a non-dental entity from controlling the professional assets of a
dental practice (such as patient records and payor contracts), employing
dentists to practice dentistry (or, in certain states, employing dental
hygienists or dental assistants), controlling the content of a dentist's
advertising or professional practice or sharing professional fees with
non-dental entities. The laws of many states also prohibit dental practitioners
from paying any portion of fees received for dental servies in consideration for
the referral of a patient. In addition, many states impose limits on the tasks
that may be delegated by dentists to dental assistants.

     State dental boards do not generally interpret these prohibitions as
preventing a non-dental entity from owning non-professional assets used by a
dentist in a dental practice or providing management services to a dentist
provided that the following conditions are met: a licensed dentist has complete
control and custody over the professional assets; the non-dental entity does not
employ or control the dentists (or, in some states, dental hygienists or dental
assistants); all dental services are provided by a licensed dentist; licensed
dentists have control over the manner in which dental care is provided and all
decisions affecting the provision of dental 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
    
                                       50
<PAGE>
   
management fee be a flat fee or cost-plus fee based on the cost of services
performed by the Company. In general, the state dental practice acts do not
address or provide any restrictions concerning the manner in which companies
account for revenues from a dental practice subject to the above-noted
restrictions relating to control over the professional activities of the dental
practice, ownership of the professional assets of a dental practice and payments
for management services.

     The Company does not control the practice of dentistry or employ dentists
to practice dentistry. Moreover, in states in which it is prohibited the Company
does not employ dental hygienists or dental assistants. The Company provides
management services to its affiliates practices, and 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 its
affiliated dental practices within the meaning of those terms under the state
dental practice acts.

     In addition, 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 arrangements other than various types of
fee for service arrangements is an unsettled area of law and are subject to
interpretation by regulators with broad discretion. As the Company or its
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 the affiliated dental
practices are engaged in the business of insurance, because some of the managed
care contracts to which the Company is a party 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 the
affiliated practices are determined to be engaged in the business of insurance,
the Company could be required either to seek licensure as an insurance company
or to change the form of its relationships with third-party payors, and the
Company's revenues may be adversely affected.
    
     REGULATORY COMPLIANCE
   
     The Company regularly monitors developments in laws and regulations
relating to dentistry. The Company may be required to modify its agreements,
operations and marketing from time to time in response to changes in the
business, statutory and regulatory environment. The Company plans to structure
all of its agreements, operations and marketing in accordance with applicable
law, although there can be no assurance that its arrangements will not be
successfully challenged or that required changes may not have a material adverse
effect on operations or profitability.
    
COMPETITION

     The dental care industry is highly fragmented, comprised principally of
sole practitioners and group practices of dental and orthodontic services. The
dental practice management industry is subject to continuing changes in the
provision of services and the selection and compensation of providers. The
Company is aware of several groups attempting to acquire or manage dental
practices. Certain of the Company's competitors are larger and better
capitalized, may provide a wider variety of services, may have greater
experience in providing dental care management services and may have longer
established relationships with buyers of such services.

     In certain markets, the demand for dental care professional personnel
presently exceeds the supply of qualified personnel. As a result, the Company
experiences competitive pressures for the recruitment and retention of qualified
dentists to deliver their services. The Company's future success depends in part
on its ability to continue to recruit and retain qualified dentists to serve as
employees or independent contractors of the affiliated dental practices. There
can be no assurance that the Company will be able to recruit or retain a
sufficient number of competent dentists to continue to expand its operations.

EMPLOYEES
   
     As of October 15, 1996, the Company employed approximately 432
administrative and dental office personnel on a full-time or part-time basis,
and the affiliated dental practices employed approximately 73 general dentists
and 15 specialists on a full-time or part-time basis. Following consummation of
the Pending
    
                                       51
<PAGE>
   
Acquisitions, the Company expects that approximately 350 additional people will
be employed on a full-time or part-time basis by the Company and approximately
150 people will be employed on a full-time or part-time basis by the affiliated
dental practices. In addition, as a component of its acquisition strategy, the
Company frequently enters into employment or consulting agreements with the
dentists from whom it acquires affiliated practices. The Company believes that
its relations with its employees are good. The Company believes that it may need
to hire additional personnel to accommodate the demands prompted by the
provision of services to each of the affiliated practices under the management
services agreements, as well as to pursue its growth strategies.
    
FACILITIES

     The Company leases approximately 12,000 square feet of space for executive,
administrative, sales and marketing and operations offices in Houston, Texas.
The Company's initial lease term expires May 2000, which may be extended at the
Company's option for an additional 60 months.

     All of the Company's existing centers are leased. Nine of the centers,
including seven of the American Dental Centers locations, are owned by
affiliates of the companies from whom the Company acquired affiliated dental
practices. All such facilities leased by the Company are leased on a not less
favorable to the Company than fair market value basis.

     The Company intends to lease centers or arrange with third parties to
build-to-suit dental centers for lease by the Company. Certain leases provide
for fixed minimum rentals and provide for additional rental payments for common
area maintenance, insurance and taxes. The leases carry varying terms expiring
between 1996 and 2006 excluding options to renew.

     The majority of all centers are located in retail locations. The Company
believes that its leased facilities are well maintained, in good condition and
adequate for its current needs. Furthermore, the Company believes that suitable
additional or replacement space will be available when required.

CORPORATE LIABILITY AND INSURANCE

     The provision of dental services entails an inherent risk of professional
malpractice and other similar claims. Although the Company does not influence or
control the practice of dentistry by dentists or have responsibility for
compliance with certain regulatory and other requirements directly applicable to
dentists and dental groups, the contractual relationship between the Company and
the affiliated dental practices may subject the Company to some medical
malpractice actions under various theories, including successor liability. There
can be no assurance that claims, suits or complaints relating to services and
products provided by managed practices will not be asserted against the Company
in the future. The availability and cost of professional liability insurance has
been affected by various factors, many of which are beyond the control of the
Company. The cost of such insurance to the Company and its affiliated dental
practices may have an adverse effect on the Company's operations.

     The Company requires each affiliated dental practice to maintain
comprehensive general liability and professional liability coverage covering the
practice and each dentist retained or employed by the affiliated dental
practice, which normally provide for comprehensive general liability coverage of
$1,000,000 for each occurrence and $2,000,000 annual aggregate, and professional
liability coverage of not less than $500,000 for each occurrence and $1,500,000
annual aggregate.

     The Company maintains other insurance coverages including general
liability, property, business interruption and workers' compensation, which
management considers to be adequate for the size of the Company and the nature
of its business.

LITIGATION
   
     The Company and the affiliated dental practices are parties to various
lawsuits from time to time in the ordinary course of their respective
businesses. Management does not believe that any of the claims currently
outstanding would have a material adverse effect on the Company's business if

     OPTION GRANTS.  The Company did not issue any stock options during 1995.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
   
     The Board of Directors did not have a Compensation Committee during 1995.
As a result, the Board of Directors, then consisting of Jack H. Castle, Jr.,
Jack H. Castle, D.D.S. and Loretta Castle, made all decisions concerning
executive officer compensation. Loretta Castle is the mother of Jack H. Castle,
Jr. and the wife of Jack H. Castle, D.D.S.

     In December 1995, the Company acquired all of the stock of Jack H. Castle,
D.D.S., Inc., a professional corporation of which Dr. Castle, a Director of the
Company, was the sole owner. In connection with that transaction, the Company
paid Dr. Castle $6,000,000 in cash and entered into a Deferred Compensation
Agreement with Dr. Castle pursuant to which the Company has agreed to pay Dr.
Castle $2,630,000 in 20 quarterly installments beginning March 1996. Proceeds of
this offering will be used to discharge the Company's obligations under the
Deferred Compensation Agreement. See "Use of Proceeds." In connection with the
purchase of the stock of Jack H. Castle, D.D.S., Inc., the Company also entered
into a Management Services Agreement with Jack H. Castle, D.D.S., P.C., a
professional corporation of which Dr. Castle is the sole owner. Pursuant to the
Management Services Agreement, Dr. Castle receives an annual payment of $100,000
for services performed in connection therewith.

     The Company is party to a lease agreement with Goforth, Inc., a company
owned by Jack H. Castle, Jr., the Company's Chairman and Chief Executive
Officer. The lease agreement relates to the Castle Dental Center located at 2101
West Loop South in Houston, Texas, a 6,781 square foot free-standing building.
The Company has agreed to pay Goforth, Inc. a minimum guaranteed rental of
$12,000 per month through January 2001 and $13,200 per month from January 2001
through January 2006. The Company has also agreed to pay additional rent of
approximately $1,600 per month for insurance, taxes and common area maintenance.
The Company believes that this lease agreement is on terms no less favorable to
the Company than could have been obtained with an independent third party.

     Pursuant to a Registration Rights Agreement dated as of December 18, 1996,
the members of the Castle Family and other parties have been granted certain
registration rights by the Company with respect to the shares of Common Stock
owned by them. See "Description of Capital Stock of the Company_-- Registration
Rights," and "Certain Transactions."
    
STOCK OPTION PLANS

OMNIBUS STOCK AND INCENTIVE PLAN

     In January 1996, the Board of Directors adopted, and the stockholders of
the Company approved, the Castle Dental Centers, Inc. Omnibus Stock and
Incentive Plan (the "Plan"). The purpose of the Plan is to advance the
interests of the Company, by providing for the acquisition of an equity interest
in the Company by its key employees, by providing additional incentives and
motivation toward superior performance by key employees of the Company, and by
enabling the Company to attract and retain the services of key employees on
whose judgment, interest and special effort the successful conduct of the
Company's operations is largely dependent. The aggregate amount of Common Stock
with respect to which grants under the Plan may be made may not exceed 1,000,000
shares.

     The Plan provides for the grant of incentive stock options ("ISOs") as
defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), nonqualified stock options and shares of restricted stock
(collectively, the "Awards"). Following the consummation of this offering, the
Plan will be administered by the Compensation Committee. Prior to the formation
of the Compensation Committee, the Plan was administered by the Company's full
Board of Directors. The Compensation Committee has, subject to the terms of the
Plan, the sole authority to grant Awards under the Plan, to construe and
interpret the Plan and to make all other determinations and take any and all
actions necessary or advisable for the administration of the Plan.

     All of the employees, Directors, consultants and former consultants of the
Company or its affiliates are eligible to receive Awards under the Plan. In
addition, key employees of entities managed by the Company may receive Awards.
Only key employees of the Company are eligible to receive ISOs. Options 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 Compensation Committee. 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 the Common
Stock). Restricted stock granted under the Plan will have such terms, conditions
and restrictions as the Compensation Committee shall determine.

     The exercise price for ISOs granted under the Plan may be no less than the
fair market value of the Common Stock on the date of grant (or 110% in the case
of ISOs granted to employees owning more than 10% of the Common Stock). The
exercise price for nonqualified options granted under the Plan will be at the
discretion of the Compensation Committee.

     The Company currently has granted Awards to purchase a total of
approximately 380,500 shares of Common Stock under the Plan at prices per share
ranging from $5.00 to $6.75, including stock options granted to Seth L. Miller
of 50,000 shares and to John M. Slack of 40,000 shares. At or shortly after this
offering, the Company anticipates that it will grant options to purchase
approximately 200,000 additional shares of Common Stock under the Plan at the
initial public offering price. Generally, the outstanding options are, and
options to be granted will be, exercisable one year from the date of grant as to
20% of the underlying shares, and as to an additional 20% on each of the next
four anniversaries of the date of option grant.

DIRECTORS' STOCK OPTION PLAN

     In August 1996, the Board of Directors adopted the Directors' Plan. The
purpose of the Directors' Plan is to encourage ownership of Common Stock by
eligible non-employee Directors of the Company and to provide increased
incentive for such directors to render services and to exert maximum effort for
the business success of the Company. In addition, the Company believes that the
Directors' Plan will further

                                       58
<PAGE>
   
strengthen the identification of directors with the stockholders. The aggregate
amount of Common Stock with respect to which grants under the Directors' Plan
may be made may not exceed 300,000 shares.
    
     The Directors' Plan provides for the automatic grant of 25,000 nonqualified
stock options (the "Options") to non-employee Directors at the time they
become Directors. The Directors' Plan will be administered by the Compensation
Committee, which has, subject to the terms of the Directors' Plan, the sole
authority to grant Options under the Directors' Plan, to construe and interpret
the Directors' Plan and to make all other determinations and take any and all
actions necessary or advisable for the administration of the Directors' Plan.

     All non-employee Directors are eligible to receive Options under the
Directors' Plan. Options will be exercisable during a ten-year period from the
date of grant of the Options and will vest based upon the number of full years
of service a non-employee Director serves on the Board of Directors as follows:
20% after one full year of service, 40% after two full years of service, 60%
after three full years of service, 80% after four full years of service and 100%
after five full years of service. No option will remain exercisable later than
ten years after the date of grant.

     The exercise price for Options granted under the Directors' Plan may be no
less than the fair market value of the Common Stock on the date of grant.
   
     The Company anticipates that prior to or upon the consummation of this

Management Partners Ltd., the investment advisor to the Pecks Investors, which

Series A Convertible Preferred Stock or Common Stock following conversion of
Series A Convertible Preferred Stock are maintained, such investors have the
contractual right to nominate one member of the Company's Board of Directors.
See "Management -- Directors and Executive Officers." At the closing of this
offering, all of the shares of Series A Convertible Preferred Stock will be
converted into Common Stock and the Senior Subordinated Notes will be paid. See

     In December 1995, the Company acquired all of the stock of Jack H. Castle,
D.D.S., Inc., a professional corporation of which Dr. Castle, a Director of the
Company, was the sole owner. In connection with that transaction, the Company
paid Dr. Castle $6,000,000 in cash and entered into a Deferred Compensation
Agreement with Dr. Castle pursuant to which the Company has agreed to pay Dr.
Castle $2,630,000 in 20 quarterly installments beginning March 1996. Proceeds of
this offering will be used to discharge the Company's obligations under the
Deferred Compensation Agreement. See "Use of Proceeds." In connection with the
purchase of the stock of Jack H. Castle, D.D.S., Inc., the Company also entered
into a Management Services Agreement with Jack H. Castle, D.D.S., P.C., a
professional corporation of which Dr. Castle is the sole owner. Pursuant to the
Management Services Agreement, Dr. Castle receives an annual payment of $100,000
for services performed in connection therewith.

     The Company has entered into a definitive agreement to acquire certain
assets of Jules V. Lane D.D.S. d/b/a American Dental Centers, J.V. Lane
Professional Corporation d/b/a American Dental Centers and Lisadent Corp.
(collectively, "American Dental Centers") for an aggregate consideration of
$20 million in cash and $5 million in shares of Common Stock valued at the
initial public offering price. On the consummation of the acquisition of
American Dental Centers, the Company has agreed to enter into a three-year
employment agreement with Dr. Lane containing noncompetition provisions pursuant
to which the Company will pay Dr. Lane an annual salary of $200,000. The Company
also has agreed to use its best efforts to nominate and elect Dr. Lane to the
Board of Directors of the Company for the longer of three years or the period of
time that Dr. Lane remains an employee of the Company on substantially the same
terms and conditions as contemplated by his employment agreement. The Company
will also enter into a registration rights agreement with Dr. Lane providing Dr.
Lane with certain piggyback registration rights with respect to the Common Stock
issued in connection with the acquisition. Additionally, at the closing of the
New York Acquisition, a professional corporation of which Dr. Lane is the sole
shareholder will enter into a Management Services Agreement with the Company.
Upon consummation of and as a condition to closing the New York Acquisition, the
Company will enter into an arrangement with Dr. Lane for the lease of certain
properties in the New York metropolitan area on which affiliated dental
practices are located. In addition, the Company will enter into an arrangement
with Dr. Lane which will provide for the Company's ongoing relationship with
AMLI.

     The Company is party to a lease agreement with Goforth, Inc., a company
owned by Jack H. Castle, Jr., the Company's Chairman and Chief Executive
Officer. The lease agreement relates to the Castle Dental Center located at 2101

The

                                       60
<PAGE>
Company has agreed to pay Goforth, Inc. a minimum guaranteed rental of $12,000
per month through January 2001 and $13,200 per month from January 2001 through
January 2006. The Company has also agreed to pay additional rent of
approximately $1,600 per month for insurance, taxes and common area maintenance.
The Company believes that this lease agreement is on terms no less favorable to
the Company than could have been obtained with an independent third party.

     Pursuant to a Registration Rights Agreement dated as of December 18, 1996,
the Pecks Investors, GulfStar Investments, Ltd. and the members of the Castle
Family have been granted certain registration rights by the Company with respect

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of the Company consists of 35,000,000 shares
of capital stock which includes 30,000,000 shares of Common Stock and 5,000,000
shares of Preferred Stock ("Preferred Stock"), 1,244,737 shares of which have
been designated Series A Convertible Preferred Stock all of which will be
converted into an aggregate of 1,244,737 shares of Common Stock at the closing
of this offering.

COMMON STOCK

     Holders of Common Stock are entitled to one vote for each share held of
record on all matters to be submitted to a vote of the stockholders, and such
holders do not have cumulative voting rights. Subject to preferences that may be
applicable to any outstanding shares of Preferred Stock, holders of Common Stock
are entitled to receive ratably such dividends, if any, as may be declared from
time to time by the Board of Directors of the Company out of funds legally
available therefor. See "Dividend Policy." All outstanding shares of Common
Stock are, and the shares to be sold in this offering when issued and paid for
will be, fully paid and nonassessable and the holders thereof will have no
preferences or conversion, exchange or preemptive rights. In the event of any
liquidation, dissolution or winding-up of the affairs of the Company, holders of
Common Stock will be entitled to share ratably in the assets of the Company
remaining after payment or provision for payment of all of the Company's debts
and obligations and liquidation payments to holders of outstanding shares of
Preferred Stock, if any.

PREFERRED STOCK

     The Preferred Stock may be issued in one or more series without further
stockholder authorization, and the Board of Directors is authorized to fix and
determine the terms, limitations and relative rights and preferences of the
Preferred Stock, to establish series of Preferred Stock and to fix and determine
the variations as among series. The Preferred Stock may be subject to repurchase
or redemption by the Company. The Board of Directors, without approval of the
holders of the Common Stock, can issue Preferred Stock with voting and
conversion rights (including multiple voting rights) which could adversely
affect the rights of holders of Common Stock. In addition to having a preference
with respect to dividends or liquidation proceeds, the Preferred Stock, if
issued, may be entitled to the allocation of capital gains from the sale of the
Company's assets. The Company has designated 1,244,737 shares of Preferred Stock
as Series A Convertible Preferred Stock, all of which are issued and outstanding
and owned by the Pecks Investors. See "Principal and Selling Stockholders."
All of the shares of Series A Convertible Preferred Stock will be converted into
an aggregate of 1,244,737 shares of Common Stock at the closing of this
offering.

     Although the Company has no present plans to issue any shares of Preferred
Stock following the closing of this offering, the issuance of shares of
Preferred Stock, or the issuance of rights to purchase such shares, may have the
effect of delaying, deferring or preventing a change in control of the Company
or an unsolicited acquisition proposal.

CERTAIN PROVISIONS OF CERTIFICATE OF INCORPORATION AND BYLAWS

GENERAL

     A number of provisions of the Company's Certificate of Incorporation (the
"Certificate") and Bylaws concern matters of corporate governance and the
rights of stockholders. Certain of these provisions, as well as the ability of
the Board of Directors to issue shares of Preferred Stock and to set the voting
rights, preferences and other terms thereof, may be deemed to have an
anti-takeover effect and may discourage takeover attempts not first approved by
the Board of Directors (including takeovers to which certain stockholders may
deem to be in their best interests). To the extent takeover attempts are
discouraged, temporary fluctuations in the market price of the Company's Common
Stock, which may result from actual or rumored takeover attempts, may be
inhibited. These provisions, together with the ability of the Board of Directors
to issue Preferred Stock without further stockholder action, also could delay or
frustrate the removal of incumbent Directors or the assumption of control by
stockholders, even if such removal or

                                       64
<PAGE>
assumption would be beneficial to stockholders of the Company. These provisions
also could discourage or make more difficult a merger, tender offer or proxy
contest, even if a transaction or contest could be favorable to the interests of
stockholders, and could potentially depress the market price of the Common
Stock. The Board of Directors of the Company believes that these provisions are
appropriate to protect the interests of the Company and all of its stockholders.
The Board of Directors has no present plans to adopt any other measures or
devices which may be deemed to have an "anti-takeover effect."

MEETINGS OF STOCKHOLDERS

     The Company's Bylaws provide that a special meeting of stockholders may be
called only by the Chief Executive Officer, by a majority of the Board of
Directors, or by a majority of the executive committee (if any). The Company's
Bylaws provide that only those matters set forth in the notice of the special
meeting may be considered or acted upon at that special meeting.

NO STOCKHOLDER ACTION BY WRITTEN CONSENT

     The Certificate provides that any action required or permitted to be taken
by the stockholders of the Company at an annual or special meeting of
stockholders must be effected at a duly called meeting and may not be taken or
effected by a written consent of stockholders in lieu thereof.

INDEMNIFICATION AND LIMITATION OF LIABILITY

     The Certificate of the Company provides that Directors and officers of the
Company shall be, and at the discretion of the Board of Directors non-officer
employees and agents may be, indemnified by the Company to the fullest extent
authorized by Delaware law, as it now exists or may in the future be amended,
against all expenses and liabilities actually and reasonably incurred in
connection with service for or on behalf of the Company, and further permits the
advancing of expenses incurred in defense of claims. The Certificate also
contains a provision permitted by Delaware law that generally eliminates the
personal liability of Directors for monetary damages for breaches of their
fiduciary duty.

AMENDMENT OF THE BYLAWS

     The Bylaws of the Company provide that an amendment or repeal thereof must
first be approved by the Board of Directors or by affirmative vote of the
holders of at least 66 2/3% of the total votes eligible to be cast by holders of
voting stock with respect to such amendment or repeal.

ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER PROPOSALS AND STOCKHOLDER NOMINATIONS
OF DIRECTORS

     The Company's Bylaws establish an advance notice procedure with regard to
the nomination, other than by or at the direction of the Board of Directors or a
committee thereof, of candidates for election as directors (the "Nomination
Procedure") and with regard to other matters to be brought by stockholders
before an annual meeting of stockholders of the Company (the "Business
Procedure").

     The Nomination Procedure requires that a stockholder give prior written
notice, in proper form, of a planned nomination for the Board of Directors to
the Secretary of the Company. The requirements as to the form and timing of that
notice are specified in the Company's Bylaws. If the Chairman of the Board of
Directors determines that a person was not nominated in accordance with the
Nomination Procedure, such person will not be eligible for election as a
director.

     Under the Business Procedure, a stockholder seeking to have any business
conducted at an annual meeting must give prior written notice, in proper form,
to the Secretary of the Company. The requirements as to the form and timing of
that notice are specified in the Company's Bylaws. If the Chairman of the Board
of Directors determines that the other business was not properly brought before
such meeting in accordance with the Business Procedure, such business will not
be conducted at such meeting.

     Although the Company's Bylaws do not give the Board of Directors any power
to approve or disapprove stockholder nominations for the election of directors
or of any other business desired by stockholders to be conducted at an annual or
any other meeting, the Company's Bylaws (i) may have the effect of precluding a
nomination for the election of directors or precluding the conduct of business
at a

                                       65
<PAGE>
particular annual meeting if the proper procedures are not followed or (ii) may
discourage or deter a third party from conducting a solicitation of proxies to
elect its own slate of directors or otherwise attempting to obtain control of
the Company, even if the conduct of such solicitation or such attempt might be
beneficial to the Company and its stockholders.

DELAWARE TAKEOVER STATUTE

     The Company is subject to Section 203 of the Delaware General Corporation
Law which, with certain exceptions, prohibits a Delaware corporation from
engaging in any of a broad range of business combinations with any "interested
stockholder" for a period of three years following the date that such
stockholder became an interested stockholder, unless: (i) prior to such date,
the Board of Directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder, (ii) upon consummation of the transaction which resulted
in the stockholder 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 for purposes of
determining the number of shares outstanding those shares owned (a) by persons
who are directors and officers and (b) by employee stock plans in which employee
participants do not have the right to determine confidentially whether shares
held subject to the plan will be tendered in a tender or exchange offer, or
(iii) on or after such date, the business combination is approved by the Board
of Directors and authorized at an annual or special meeting of stockholders by
the affirmative vote of at least 66 2/3% of the outstanding voting stock which
is not owned by the interested stockholder. An "interested stockholder" is
defined as any person that is (a) the owner of 15% or more of the outstanding
voting stock of the corporation or (b) an affiliate or associate of the
corporation and was the owner of 15% or more of the outstanding voting stock of
the corporation at any time within the three-year period immediately prior to
the date on which it is sought to be determined whether such person is an
interested stockholder.

REGISTRATION RIGHTS
   
     The Company has granted to the Pecks Investors, the Castle Family and
GulfStar Investments Ltd. certain registration rights pursuant to a Registration

the Pending Acquisitions, a total of 6,196,980 shares of Common Stock, assuming

Preferred Stock the right to request the registration of all or part of such
Common Stock. On receipt of such request, the Company is required to use its
best efforts to effect such registration. The Pecks Investors may exercise their
right to request registration twice following the consummation of this offering.
Additionally, following the consummation of this offering, the Pecks Investors
holding at least 20% of the Common Stock issuable on conversion of the Series A
Convertible Preferred Stock have the right to request an unlimited number of
registrations of all or part of their Common Stock on Form S-3 at such time as
the Company is eligible to use such form. All registrations pursuant to the
Registration Rights Agreement are undertaken at the Company's expense.

     If the Company proposes to register any of its securities under the
Securities Act, either for its own account or the account of holders of Common
Stock exercising registration rights, the Company is required to give notice to
all parties to whom the Company has granted registration rights and to offer to
include any shares of Common Stock owned by such parties in such registration.
The exercise of these rights is subject to a number of conditions, including the
right of the underwriters of such offering to limit the number of shares
included in such registration. In the event the underwriters so limit the number
of shares to be included in a registration, any shares requested to be included
in such registration by the Pecks Investors,

                                       66

the Castle Family and GulfStar Investments Ltd. shall be included prior to the
inclusion of any shares of Common Stock requested to be included by any other
party.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Company's Common Stock is KeyCorp
Shareholder Services, Inc.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
     Upon completion of this offering and consummation of the Pending
Acquisitions (assuming an initial public offering price of $10.00), and giving
effect to the conversion of the Series A Convertible Preferred Stock the Company
will have 11,696,980 shares of Common Stock outstanding. Up to 139,757 shares of
Common Stock are presently issuable on the conversion of two Seller Notes issued
by the Company. Of the outstanding shares, the 5,500,000 shares sold in this
offering (6,325,000 shares if the Underwriters exercise their over-allotment
option in full) will be freely tradable without restriction or limitation under
the Securities Act, except to the extent such shares are subject to the
agreement with the Underwriters described below, and except for any such shares
which may be acquired by an "affiliate" of the Company as that term is defined
in Rule 144 ("Affiliate"). The 6,196,980 remaining shares constitute
"restricted securities" within the meaning of Rule 144, and will only be
eligible for sale in the open market commencing on the second anniversary of the
date such shares were acquired from the Company or an Affiliate, subject to
contractual lockup provisions and applicable requirements of Rule 144 and Rule
701 ("Rule 701") described below. Some of such restricted securities, however,
are subject to registration rights which may entitle the holder thereof to
register such shares for resale under the Securities Act and to sell such shares
after the lockup period without regard for the restrictions of Rule 144. The
restricted shares were issued and sold by the Company in private transactions in
reliance upon exemptions from registration under the Securities Act. The Company
will also have outstanding the GulfStar Warrant, which is exercisable for
113,158 shares of Common Stock at $5.50 per share, and such shares will be
eligible for resale subject to the volume, holding period and certain other
limitations of Rule 144 upon their exercise or conversion, as applicable.
    
     In general, under Rule 144, as currently in effect, if a period of at least
two years has elapsed between the later of the date on which restricted
securities were acquired from the Company and the date on which they were
acquired from an Affiliate, then the holder of such restricted securities
(including an Affiliate) is entitled to sell a number of shares within any
three-month period that does not exceed the greater of (i) one percent of the
then outstanding shares of the Common Stock or (ii) the average weekly reported
volume of trading of the Common Stock during the four calendar weeks preceding
such sale. Sales under Rule 144 are also subject to certain requirements
pertaining to the manner of such sales, notices of such sales and the
availability of current public information concerning the Company. Affiliates
may sell shares not constituting restricted securities in accordance with the
foregoing volume limitations and other requirements but without regard to the
two year holding period. Under Rule 144(k), if a period of at least three years
has elapsed between the later of the date on which restricted securities were
acquired from the Company and the date on which they were acquired from an
Affiliate, a holder of such restricted securities who is not an Affiliate at the
time of the sale and has not been an Affiliate for a least three months prior to
the sale would be entitled to sell the shares immediately without regard to the
volume limitations and other conditions described above.

     The Company, its directors and executive officers and all of the
stockholders of the Company have agreed that, for a period of 180 days after the
date of this Prospectus, they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any shares of Common Stock, except in the case of the Company,
in certain limited circumstances, including issuing up to 2,000,000 shares of
Common Stock in connection with acquisitions to parties that agree to be bound
by the same restriction on offers and sales. After this offering, sales of
substantial amounts of Common Stock by existing stockholders could have an
adverse impact on the market price of the Common Stock. No

                                       67
<PAGE>
predictions can be made as to the effect, if any, that market sales of shares by
existing stockholders or the availability of such shares for future sale will
have on the market price of shares of Common Stock prevailing from time to time.
   
     Under the Plan and the Directors' Plan, there is an aggregate of 1,300,000
shares reserved for issuance. As of the date of this Prospectus, options to
purchase 330,500 shares have been granted pursuant to the Plan, none of which
are currently exercisable. In addition, the Company intends to issue at or
shortly following consummation of this offering options to purchase
approximately 200,000 shares of Common Stock under the Plan and 150,000 shares
of Common Stock under the Directors' Plan (none of which will be immediately
exercisable). As soon as practicable following the consummation of the offering,
the Company intends to file a registration statement under the Securities Act to
register the shares of Common Stock reserved for issuance under the Plan and the
Directors' Plan. Shares of Common Stock issued pursuant to the Plan and the
Directors' Plan after the effective date of such registration statement will be
available for sale in the open market, subject to vesting provisions related to
such shares and the Lock-up Period. If the Company does not file such a
registration statement during the Lock-up Period, holders of shares issuable
upon exercise of options will be able to rely on the exemption from registration
under Rule 701. Securities issued in reliance on Rule 701 are restricted
securities and at the expiration of the Lock-up Period, may be sold by persons
other than affiliates subject only to the manner of sale provisions of Rule 144
and by affiliates under Rule 144 without compliance with its two-year minimum
holding period.
    
     The Securities and Exchange Commission has recently proposed reducing the
initial Rule 144 holding period to one year and the Rule 144(k) holding period
to two years. There can be no assurance as to when or whether such rule changes
will be enacted. If enacted, such modification will have a material effect on
the time when certain shares of the Common Stock become eligible for resale.

     Under the terms and subject to the conditions contained in the Underwriting

                                        ==========

     The Underwriters are committed to take and pay for all of the shares of
Common Stock offered hereby (other than those covered by the over-allotment
option described below) if any such shares are taken.
   
     The Underwriters, for whom Smith Barney Inc., Donaldson, Lufkin & Jenrette
Securities Corporation and Southcoast Capital Corporation are acting as
Representatives, propose initially to offer part of the shares of Common Stock
directly to the public at the public offering price set forth on the cover page
hereof and part to certain dealers at a price that represents a concession not
in excess of $            per share under the public offering price. The
Underwriters may allow, and such dealers may reallow, a concession not in excess
of $            per share to certain other dealers. After the initial public
offering, the public offering price and such concessions may be changed by the
Underwriters. The Representatives have informed the Company and the Selling
Stockholder that the Underwriters do not expect to confirm sales to accounts
over which they exercise discretionary authority.

     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an additional 825,000
shares, of Common Stock at the price to the public set forth on the cover page
hereof less underwriting discounts and commissions. The Underwriters may
exercise such option to purchase additional shares solely for the purpose of
covering over-allotments, if any, incurred in connection with the sale of the
shares offered hereby. To the extent such option is exercised, each Underwriter
will become obligated, subject to certain conditions, to purchase approximately
the same percentage of such additional shares as the number set forth opposite
each Underwriter's name in the preceding table bears to the total number of
shares listed in such table.

     The Company, the Selling Stockholder and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
    
     The Company, its directors and executive officers and all of the
stockholders of the Company have agreed that, for a period of 180 days after the
date of this Prospectus, they will not, without the prior written consent of
Smith Barney Inc., offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for any shares of Common Stock, except in the case of the Company,
in certain limited circumstances, including issuing up to 2,000,000 shares of
Common Stock in connection with acquisitions to parties that agree to be bound
by the same restrictions on offers and sales.

     Prior to this offering, there has not been any public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
Common Stock has been determined by negotiations between the Company and the
Representatives. Among the factors considered in determining the initial

                                       69
<PAGE>
public offering price were the history of, and prospects for, the Company's
business and the industry in which it competes, an assessment of the Company's
management and the present state of the Company's development, its past and
present revenues and earnings and the trend of such revenues and earnings, the
prospects for the growth of the Company's revenues and earning, the general
condition of the securities market at the time of this offering and the market
price and earnings of similar securities of comparable companies at the time of
this offering.

                                 LEGAL MATTERS

     The validity of the Common Stock offered hereby will be passed on for the
Company by Bracewell & Patterson, L.L.P., Houston, Texas. Certain legal matters
will be passed on for the Underwriters by Willkie Farr & Gallagher, New York,
New York.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Castle Dental Centers, Inc.:
    
     We have audited the accompanying combined balance sheets of Castle Dental
Centers, Inc. as of December 31, 1994 and 1995, and the related combined
statements of operations, equity and cash flows for each of the three years in
the period ended December 31, 1995. 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 audits.

     We conducted our audits 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 audits provide a reasonable basis for our opinion.
   
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Castle Dental
Centers, Inc. as of December 31, 1994 and 1995, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION

     Castle Dental Centers, Inc. is a provider of dental and orthodontic
services and products that owns and operates dental centers in the Houston,
Texas area.
   
     The combined financial statements reflect the combined operations of Castle
Dental Centers, Inc., Jack H. Castle, D.D.S., Inc. ("JCD"), a subchapter S
corporation, and of Family Dental Services of Texas, Inc. ("FDS"), a
corporation, because these entities were under common control. JCD is a provider
of dental and orthodontic services. Prior to December 31, 1995, under the terms
of a contractual agreement, FDS provided business operations, financial,
marketing and administrative services to JCD. All significant intercompany
accounts and transactions have been eliminated in combination.

     Effective December 31, 1995, FDS entered into an agreement and plan of
merger with Castle Dental Centers, Inc. both of which are collectively known as
Castle Dental Centers (the "Company"). The Company on December 31, 1995,
executed a stock purchase agreement, with the sole shareholder of JCD and
acquired the outstanding stock for $6,000,000 after which JCD ceased all dental
and orthodontic operations.

     Jack H. Castle, D.D.S., P.C., ("JCP"), a professional corporation, was
incorporated in December 1995 to provide dental and orthodontic services. JCP
commenced operations in January 1996.
     In connection with ICP's commencement of operations, the Company began
providing the same services to JCP as those that FDS previously provided to JCD
under similar contractual agreements.
    
     The Company has restated previously reported financial statements to accrue
allowances for doubtful accounts, compensation payable and trade accounts
payable. These restatements increased net income by $37,000 and $362,000 for
1993 and 1994, respectively, and decreased retained earnings as of January 1,
1993 by $1,635,000. The restatement had no tax effect because the adjustments
were related to the subchapter S corporation.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of net revenue and expenses during the
reporting periods. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION

     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Orthodontic revenue is recognized in accordance with
the proportional performance method. Under this method, revenue is recognized as
services are incurred under the terms of contractual agreements with each
patient. Approximately 25% of

                                      F-9

                          CASTLE DENTAL CENTERS, INC.
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
the services are performed in the first month with the remaining services
recognized ratably over the remainder of the contract. Billings under each
contract, which average approximately 28 months, are made equally throughout the
term of the contract, with final payment at the completion of the treatment.

     Accounts receivable consist primarily of receivables from patients,
insurers, government programs and other third-party payers for dental services
provided by dentists. An allowance for doubtful accounts is recorded by the
Company based on historical experience.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
ten years. Fully depreciated assets are retained in property and equipment until
they are removed from service. Fully depreciated assets as of December 31, 1994
and 1995 were $490,000. Maintenance and repairs are charged to expense whereas
renewals and major replacements are capitalized. Gains and losses from
dispositions are included in operations.

  DEBT ISSUANCE COSTS

     The costs related to the issuance of debt are capitalized and amortized
using the effective interest method over the lives of the related debt.

  INCOME TAXES

     JCD was a subchapter S entity and, accordingly, all federal tax liabilities
were the responsibility of the shareholder. The subchapter S election of JCD was
automatically terminated when the entity became a wholly-owned subsidiary of the
Company; and therefore, became a C-Corporation for federal income tax purposes.
Accordingly, a pro forma provision for income taxes is presented as if the
entities were taxed as C-corporations during the periods presented.

     Income taxes, including pro forma calculations, are accounted for under the
liability method. Under this method, deferred taxes are determined based on the
differences between the financial reporting and tax basis of assets and
liabilities and are measured using the enacted marginal tax rates currently in
effect. All federal deferred taxes of JCD were recognized upon becoming a
C-Corporation.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of," which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of SFAS No. 121 did not have a material impact on its
financial position, results of operations or cash flows.

     In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which establishes accounting and reporting standards for
stock-based employee compensation plans. The pronouncement is effective for the
year ended December 31, 1996, although earlier application regarding reporting
disclosure requirements is encouraged. Based on preliminary review, the Company
intends to adopt only the reporting disclosure provisions of SFAS No. 123. The
Company does not believe implementation of SFAS No. 123 will have a material
impact on its financial position, results of operations or cash flows.

  EARNINGS PER SHARE

     Earnings per share is computed on the basis of the weighted average number
of shares of common stock and common stock equivalents outstanding during each
period. Shares outstanding for all periods presented have been retroactively
adjusted to reflect the reorganization discussed in Note 2. In accordance with
Staff Accounting Bulletin ("SAB") Number 83 of the Securities and Exchange
Commission, the common stock equivalents that were issued during the twelve
months preceding the planned offering at prices below the expected initial
public offering price have been included in the Company's earnings per share
computation and treated as if they had been issued at the Company's inception
even though they were antidilutive. Additionally, in accordance with SAB Number
55, pro forma earnings per share have been presented for 1995 to reflect
issuance of the number of shares that would have been necessary to fund the
$6,000,000 distribution to the Company's owner in connection with the
Reorganization (at an assumed public offering price of $10.00 per share). Fully
diluted earnings per share are not presented because such amounts would be the
same as amounts computed for primary earnings per share.

  ADVERTISING

     Costs incurred for advertising are expensed when incurred.

2.  REORGANIZATION AND RELATED TRANSACTIONS:
   
     In December 1995, the Company completed a reorganization (the
"Reorganization") in which it entered into the following borrowing agreements.
    
      o   $3,000,000 revolving credit agreement ("Credit Agreement") to be
          used for acquisition financing and general corporate purposes. The
          Credit Agreement bears interest at rates that vary based on the
          lender's prime rate or the London Interbank offered rate plus
          applicable margins and expires June 30, 1997. A commitment fee is
          payable quarterly on the daily average unused amount ranging from .25%
          to .5% of such amounts. As of December 31, 1995, there was $3,000,000
          available under the line of credit.

      o   $6,000,000 bank term loan, (the "Term Loan"), which is
          collateralized by the assets of the Company. Interest is payable
          quarterly, beginning March 1996 at rates not exceeding the bank's
          prime rate plus 1% (8.19% at December 31, 1995). Principal payments of
          $300,000 are payable quarterly, commencing June 15, 1996 through March
          15, 2001.

      o   $7,500,000 face amount of subordinated notes (the "Subordinated
          Notes"). The Subordinated Notes are uncollateralized, bear interest
          at 12% per year and are payable quarterly in arrears. Principal is
          payable in two installments of $3.75 million on December 18, 2001 and
          2002.

     The Company issued 1,244,737 shares of Series A convertible preferred
stock, par value $.001 per share (the "Series A Stock") to the buyers of the
Subordinated Notes. Each share is convertible into one share of the Company's
common stock after giving effect to any antidilutive adjustment as appropriate.
The Series A Stock is mandatorily redeemable at the fair market value at the
date of redemption at the holder's option either upon receipt of a change of
control notice or after December 18, 2001, if no secondary market exists for
Series A Stock. The value of the Series A Stock issued ($2.52 per share) has
been recorded as a discount on the Subordinated Notes. The Company has the right
to call all the shares of the Series A Stock at $.001 per share, upon a
completed or anticipated change of control.

     A portion of the proceeds were used to acquire JCD, the acquisition of
which has been recorded as a recapitalization and capital distribution to JCD's
shareholder because the Company and JCD were under common control. Additionally,
the Company issued 4,000,000 shares to the former owner of JCD and certain
related parties for no consideration. Accordingly, the Company retroactively
applied the shares issued to all historical financial statements as a stock
split.

                                      F-11
<PAGE>
                          CASTLE DENTAL CENTERS, INC.
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

     In connection with the purchase of the stock of JCD, the Company entered
into a Deferred Compensation Agreement with the sole shareholder of JCD, who is
also director of the Company, pursuant to which the Company has agreed to pay
the shareholder $2,630,000 in 20 quarterly installments beginning March 1996.
Payments made by the Company pursuant to the Deferred Compensation Agreement are
subordinated to the Credit Agreement, the Term Loan and the Subordinated Notes.

     A warrant to purchase 113,158 shares of common stock at an exercise price
of $5.50 per share was issued to an investment advisor in connection with the
placement of the recapitalization (See Note 9). The warrant is exercisable at
any time prior to its expiration date of December 18, 2000. The value of the
warrant ($0.82 per share) has been recorded as deferred offering costs of the
Subordinated Notes.

     The Company is required to repurchase all outstanding Subordinated Notes in
the event of a change in control or if no secondary market exists at December
18, 2001. The Subordinated Notes are subordinate to certain senior indebtedness
of the Company. Approximately $695,000 of debt issuance costs, including the
value of the warrant, were capitalized in relation to the issuance of the Credit
Agreement, Term Loan, and Subordinated Notes. Additionally, approximately
$210,000 of issuance cost were charged to the Series A Stock.

     The Credit Agreement, Term Loan, and Subordinated Notes contain customary
restrictive covenants which include, among others, restrictions on additional
indebtedness, the payment of dividends and other distributions, and require the
Company to meet certain financial ratios.
   
     The Company intends to complete an initial public offering during the
fourth quarter of 1996. The proceeds from the offering will be used to repay
approximately $7.5 million of the 12% Subordinated Notes and approximately $6.0
million under the term loan. Pro forma loss per share would have been $0.38 for
the period ended December 31, 1995 had the offering proceeds been used for
retirement of such debt at the beginning of 1995.

  LITIGATION

     The Company is from time to time subject to claims and suits arising in the
ordinary course of operations. In the opinion of management, the ultimate
resolution of such pending legal proceedings will not have a material adverse
effect on the Company's financial position, results of operations or liquidity.

  DENTIST EMPLOYMENT AGREEMENTS AND PROFESSIONAL LIABILITY

     Each affiliated dental practice has entered into a Dentist Employment
Agreement with each full time dentist, orthodontist and other dental specialist
employed by it. Although the form of contract varies somewhat among practices
and among dentists with different specialties, the typical contract provides for
a defined compensation arrangement, including performance-based compensation,
liquidated damages and a covenant not to compete. Each full-time dentist is
required to maintain professional liability insurance, and mandated coverage
limits are generally at least $1,000,000 per claim and $1,000,000 in aggregate.
In addition, many affiliated dental practices employ part-time dentists. Not all
part-time dentists have employment agreements, but all part-time dentists are
required to carry professional liability insurance in specified amounts.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable and credit agreement approximate fair values due to the
short-term maturities of these instruments. The carrying amounts of the
Company's long-term borrowings as of December 31, 1994 and 1995, respectively,
approximate their fair value based on the Company's current incremental
borrowing rates for similar type of borrowing arrangements.

9.  RELATED PARTY TRANSACTIONS:
   
     The Company entered into a Management Services Agreement with JCP, a
professional corporation of which a shareholder is the sole owner. Pursuant to

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
installments pursuant to a vesting schedule. No option will remain exercisable
later than ten years after the date of grant.

     The exercise price for ISOs granted under the Plan may be no less than the
fair market value of the common stock on the date of grant (or 110% in the case
of ISOs granted to employees owning more than 10% of the common stock). The
exercise price for nonqualified options granted under the Plan will be at the
discretion of the Company.

  ACQUISITIONS

     In May 1996, the Company acquired the assets of and entered into long term
management agreements with 1st Dental Care, P.A., a dental practice in the
Tampa/Clearwater, Florida area, and Mid-South Dental Centers, P.C., a dental
practice with dental centers in various locations in Tennessee. In August 1996,
the Company increased its dental practices under management in Texas by the
acquisition of the assets of Horizon Dental Centers, a dental practice with
dental centers in Fort Worth and Austin, Texas. The purchase prices consisted
primarily of combinations of cash, common stock and seller debt issued. The
Company has entered into definitive agreements to acquire the assets of and
enter into a long term management agreement with American Dental Centers, a
dental practice in the New York City area, and United Dental Care, a dental
practice that operates dental centers in Arkansas, Oklahoma and Louisiana.

  AMENDMENT TO TERM LOAN

     In May 1996, the Company amended the Term Loan, which increased the amount
available to $16 million. The additional $10 million is to be utilized to fund
acquisitions, which are subject to prior approval by the lender. As of June 30,
1996, the Company had borrowed $3,950,000 of this facility to fund the
acquisition of 1st Dental Care in Tampa/Clearwater, Florida and Mid-South Dental
Centers in Nashville, Tennessee, discussed above. In August 1996, the Company
borrowed an additional $2.1 million under the term loan to fund the acquisition
of Horizon Dental Centers in Fort Worth and Austin, Texas, discussed above.

  EMPLOYEE RETIREMENT PLAN

Section 401(k) of the Internal Revenue Code of 1986 (the "401(k) Plan"). All
employees of the Company are eligible to participate in the 401(k) Plan upon the
completion of six months of service. Participants may elect to defer receipt of
compensation and have such deferred amounts contributed to the 401(k) Plan up to
a maximum of 20% of compensation. The Company may match contributions made by
participants under the 401(k) Plan each year in an amount determined by the
Company on a year-to-year basis. Participants are fully vested with respect to
their contributions, while the Company's contributions are subject to vesting on
the following basis: zero for fewer than two years of employment and 20% per
year cumulatively for the third through seventh years of employment.
Participants may borrow from their accounts under the 401(k) Plan.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholder of
  1st Dental Care:

     We have audited the accompanying combined balance sheets of 1st Dental Care
as of December 31, 1994 and 1995, and the related combined statements of
operations, changes in stockholder's equity (deficit) and cash flows for each of
the three years in the period ended December 31, 1995. These combined financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these combined financial statements
based on our audits.

     We conducted our audits 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 audits provide a reasonable basis for our opinion.
   
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of 1st Dental Care as
of December 31, 1994 and 1995, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1995, in
conformity with generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION
   
     1st Dental Care (the "Company") is a provider of dental and orthodontics
services and products that owns the assets of and provides management services
to dental and orthodontic centers in northwest and west Florida. The combined
financial statements for 1995 reflect the operations of Lester B. Greenberg,
D.D.S., P.A., 1st Dental Care Inc. and M&B Dental Lab because all entities are
under common control. The combined financial statements for 1993 and 1994
reflect the combined operations of the following corporations because these
entities were under common control:
    
Bayonett Point Inc.          Holiday Inc.              Timber Pines
Boot Ranch Inc.              Lakewood Inc.             Town and Country
Crystal River Inc.           Largo Mall Inc.           First Dental Management
Carrollwood Inc.             Port Richey Inc.          First Dental P.A.
East Bay Inc.                Sear Town                 M & B Dental Lab
                             Seven Hills

     These corporations were dissolved and merged into the corporations included
in the 1995 financial statements. All significant intercompany accounts and
transactions have been eliminated in combination.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of net revenue and expenses during each
reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value because of the short maturity.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION

     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Orthodontic revenue is recognized in accordance with
the proportional performance method. Under this method, revenue is recognized as
services are incurred under the terms of contractual agreements with each
patient. Approximately 25% of the services are performed in the first month with
the remaining services recognized ratably over the remainder of the contract.
Billings under each contract, which average approximately 28 months, are made
equally throughout the term of the contract, with final payment at the
completion of the treatment.
   
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payers for services provided
by dentists. An allowance for doubtful accounts is recorded by the Company based
on historical experience.

             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
ten years. Fully depreciated assets are retained in property and equipment until
they are removed from service. Fully depreciated assets as of December 31, 1994
and 1995 were approximately $314,000. Maintenance and repairs are charged to
expenses whereas renewals and major replacements are capitalized. Gains and
losses from dispositions are included in operations.

  DEBT ISSUANCE COSTS

     The costs related to the issuance of debt are capitalized and amortized to
interest expense using the effective interest method over the life of the
related debt.

  INCOME TAXES

     The Companies are Subchapter S entities and, accordingly, all federal and
state tax liabilities are the responsibility of the shareholder.

     Income taxes for the pro forma calculations are determined under the
liability method. Under this method, deferred taxes are based on the differences
between the financial reporting and tax basis of assets and liabilities and are
measured using the enacted marginal tax rates currently in effect.

  ADVERTISING

     Advertising costs are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of" which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of SFAS No. 121 did not have a material impact on its
financial position, results of operations or cash flows.

December 31, 1995, the outstanding balance of this credit facility was $201,000.
The line of credit is payable on demand and is renewable annually with advances
amortized over a five year period. The credit agreement contains customary
restrictive covenants that include, but are not limited to, requiring the
Company to meet certain financial ratios. The Company was in compliance with all
loan covenants to which it was subject as of December 31, 1995.

     At December 31, 1995, the Company had several term loans payable to various
banks for a total principal balance of $794,000. These loans are collateralized
by the assets of the Company and have fixed interest rates ranging from 7.58% to
11.00% per year. All notes are payable in monthly installments through March
2001. In addition, the Company has a term loan collateralized by the personal
assets of the shareholders with a balance of $125,000 at December 31, 1995. The
note bears interest at a fixed rate of 16% per year and is payable in monthly
installments of principal and interest of $6,400 through January 1997.

7.  CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the creditworthiness of
patients and appropriate allowances are made to reduce accounts to their net
realizable values.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, receivables and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying amounts of the Company's fixed rate long-term
borrowings as of December 31, 1994 and 1995, respectively, approximate their
fair value.

     The carrying value of the Company's revolving credit agreement approximates
fair value because the rate on such agreement is variable, based on current
market.

8.  SUBSEQUENT EVENTS:

     On March 31, 1996, the Company closed a facility due to ongoing operating
losses. It is not management's intent to reopen this facility. The Company wrote
off certain assets associated with this facility in 1995. For the period ended
December 31, 1995, the Company recognized a loss of $41,000.

     The assets of the Company were acquired by Castle Dental Centers of Florida
in May 1996.

9.  RELATED PARTY TRANSACTIONS:

     The Company purchases dental supplies from an affiliated company
wholly-owned by the company's stockholder. For the years ended 1993 and 1994,
the Company purchased $120,000 of dental supplies from this affiliate and none
in fiscal year ended 1995.

                         NOTES TO FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION

     Mid-South Dental Centers (the "Company") is a provider of dental and
orthodontics services and products that owns and operates dental centers in the
Nashville and Chattanooga, Tennessee areas.

     The statements reflect the operations of Mid-South Dental Centers P.C.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of net revenue and expenses during each
reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value because of the short maturity.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION

     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Orthodontic revenue is recognized in accordance with
the proportional performance method. Under this method, revenue is recognized as
cost of services are incurred under the terms of contractual agreements with
each patient. Approximately 25% of services are performed in the first month
with the remaining services recognized ratably over the remainder of the
contract. Billings under each contract, which average approximately 28 months,
are made equally throughout the term of the contract, with final payment at the
completion of the treatment.
   
     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payers for services provided
by dentists. An allowance for doubtful accounts is recorded by the Company based
on historical experience.
    
  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
ten years. Fully depreciated assets are retained in property and equipment until
they are removed from service. Fully depreciated assets as of December 31, 1994
and 1995 were approximately $376,000. Maintenance and repairs are charged to
expenses whereas renewals and major replacements are capitalized. Gains and
losses from dispositions are included in operations.

  DEBT ISSUANCE COSTS

     The costs related to the issuance of debt are capitalized and amortized
using the effective interest method over the lives of the related debt.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  INCOME TAXES

     The Company is a Subchapter S entity and, accordingly, all federal and
state tax liabilities are the responsibility of the shareholder.

     Income taxes, including pro forma calculations, are determined under the
liability method. Under this method, deferred taxes are based on the differences
between the financial reporting and tax basis of assets and liabilities and are
measured using the enacted marginal tax rates currently in effect.

  ADVERTISING

     Costs incurred for advertising are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of" which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of this standard did not have a material effect on the
Company's financial position, results of operations or cash flows.

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
creditworthiness of patients and appropriate allowances are made to reduce
accounts to their net realizable values.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, receivables and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying amounts of the Company's fixed rate long-term
borrowings as of December 31, 1994 and 1995, respectively, approximate their
fair value.

     The carrying value of the Company's revolving credit agreement approximates
fair value because the rate on such agreement is variable, based on current
market.

8.  SUBSEQUENT EVENT:

     The assets of the Company were acquired by Castle Dental Centers of
Tennessee in May, 1996.

9.  RELATED PARTY TRANSACTIONS:

     The Company leased certain assets from the owner of the Company. Lease
expense related to these assets for each of the years ended 1993, 1994, and 1995
was approximately $44,000.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholder of
  Horizon Dental Centers:

     We have audited the accompanying combined balance sheet of Horizon Dental
Centers as of December 31, 1995, and the related combined statements of
operations, changes in stockholder's equity (deficit) and cash flows for each of
the two years in the period ended December 31, 1995. 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 audits.

     We conducted our audits 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 audits provide a reasonable basis for our opinion.
   
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Horizon Dental
Centers as of December 31, 1994 and 1995, and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 1995,
in conformity with generally accepted accounting principles.

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION
   
     Horizon Dental Centers (the "Company") is a provider of dental services
and products that operates dental practices in central and north Texas. The
combined financial statements for 1994 and 1995 reflect the operations of the
following corporations because these entities were under common control:
    
                                           FEDERAL INCOME
            NAME OF COMPANY                  TAX STATUS
- ----------------------------------------   ---------------
CA Dental Services, PC..................   S Corp.
NA Dental Services, PC..................   S Corp.
SCA Dental Services, PC.................   S Corp.
SA Dental Services, PC..................   S Corp.
EFW Dental Services, PC.................   C Corp.
NEFW Dental Services, PC................   C Corp.
HDC Dental Services, PC.................   C Corp.
MIDCITIES Services, PC..................   C Corp.
West Fort Worth Dental Services, PC.....   C Corp.
Austin Periodontist Assoc., Inc.........   C Corp.

     All significant intercompany accounts and transactions have been eliminated
in combination.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value because of the short maturity.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION
   
     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Accounts receivable consist primarily of receivables
from patients, insurers, and other third-party payers for dental services
provided by dentists. Such amounts are reduced by an allowance for uncollectible
accounts based on historical experience.
    
  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
seven years. Maintenance and repairs are charged to expense whereas renewals and
major replacements are capitalized. Gains and losses from dispositions are
included in operations.

  INCOME TAXES

     All federal and state income tax liabilities are the responsibility of the
shareholder for the Companies that are Subchapter S Corporations.

     The Subchapter C Corporations utilize the liability method for income
taxes. Under this method, deferred taxes are determined based on differences
between the financial reporting and tax basis of assets and liabilities and are
measured using the enacted tax rates currently in effect when the differences
reverse.

  ADVERTISING

     Advertising costs are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of," which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of SFAS No. 121 did not have a material impact on its
financial position, results of operations or cash flows.

2.  LONG-TERM DEBT:

     Long-term debt consisted of the following:

                                         DECEMBER 31,

                                        ==============

     The aggregate maturities of long-term debt as of December 31, 1995 for each
of the next five years were as follows (in thousands):

1996.................................  $     458
1997.................................        446
1998.................................        213

                                       $   1,117
                                       =========

     The Company has various fixed rate commercial promissory notes outstanding,
that are collateralized by assets used in the Company's operations. The assets
have been sold to Consolidated Industries Inc., an entity owned by the
stockholder. The Company recorded a receivable from this affiliate. The
promissory notes are payable in monthly installments of principal and interest
ranging from $8,000 to $9,000 and have varying maturity dates through 1998.
Interest rates on these notes vary at rates ranging from 17% to 21% per year.
The affiliate makes payments of principal and interest on this debt, the
principal payments are reflected as a reduction of the receivable and the debt.
The interest cost is borne by the affiliate and incorporated into the management
fees paid by the Company (see Note 6).

3.  COMMITMENT AND CONTINGENCIES:

  LITIGATION

     The Company is from time to time subject to claims and suits arising in the
ordinary course of operations. In the opinion of management, the ultimate
resolution of such pending legal proceedings will not have a material adverse
effect on the Company's financial position, results of operations or cash flows.

4.  CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the credit worthiness of
patients and appropriate allowances are made to reduce accounts to their net
realizable values.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, receivables and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying amounts of the Company's long-term borrowings as of
December 31, 1994 and 1995, respectively, approximate their fair value.

5.  AFFILIATE MANAGEMENT AGREEMENT:

     The Company has entered into a management agreement with Consolidated
Industries Inc., an entity owned by the Company's stockholder. Under the
agreement Consolidated provides services to the Company for a fixed fee. These
services include consultation and management services and the use of office
equipment and facilities. Fees paid to the affiliate were $1,694,000 and
$1,249,000 for 1994 and 1995, respectively.

6.  PROFESSIONAL FEE AND CLINICAL AGREEMENT:

     The Company has entered into professional and clinical agreements with
various professional corporations. The agreements are for services to be
provided to the Company for daily services of dentists, clinical support, and
daily management of each facility. Such fees incurred under these agreements
were $3,006,000 and $3,012,000 for 1994 and 1995, respectively.

7.  SUBSEQUENT EVENTS:
   
     Castle Dental Centers of Texas acquired certain assets and stock of the
entities described in Note 1 during August 1996.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders of Jules V. Lane, Professional Corporation, and
Lisadent Corp. and the owner of
Jules V. Lane, D.D.S.:

     We have audited the accompanying combined balance sheets of American Dental
Centers as of December 31, 1994 and 1995, and the related combined statements of
operations, changes in stockholders' equity and cash flows for each of the three
years in the period ended December 31, 1995. These combined financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these combined financial statements based on our audits.

     We conducted our audits 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 audits provide a reasonable basis for our opinion.
   
     In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of American Dental
Centers as of December 31, 1994 and 1995, and the results of its operations and
its cash flows for each of the three years in the period ended December 31,
1995, in conformity with generally accepted accounting principles.

                            AMERICAN DENTAL CENTERS
                     NOTES TO COMBINED FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION

     Jules V. Lane, Professional Corporation, doing business as American Dental
Centers (the "Company"), is a provider of dental and orthodontics services and
products in the Long Island, Westchester County and New York City, New York
areas.

     The combined statements reflect the operations of Jules V. Lane,
Professional Corporation, Jules V. Lane, D.D.S., and Lisadent Corp. because all
entities are under common control. All significant intercompany accounts and
transactions have been eliminated in combination.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of net revenue and expenses during each
reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value because of the short maturity.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION

     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Orthodontic revenue is recognized in accordance with
the proportional performance method. Under this method, revenue is recognized as
services are incurred under the terms of contractual agreements with each
patient. Approximately 25% of services are performed in the first month with the
remaining services recognized ratably over the remainder of the contract. The
remaining billings under each contract, which average approximately 28 months,
are made equally throughout the term of the contract, with final payment at the
completion of the treatment. The Company typically receives a 25% payment at the
time the contract is signed.

     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payers for services provided
by dentists. An allowance for doubtful accounts is recorded by the Company based
on historical experience.

  INVESTMENTS

     The Company has adopted Statement of Financial Accounting Standards No.
115, "Accounting for Certain Investments in Debt and Equity Securities," which
requires that investments in debt securities and marketable equity securities be
designated as trading, held-to-maturity or available for sale. At
December 31, 1994 and 1995, investments have been categorized as available for
sale, are stated at amortized cost, which approximates fair market value, and
are classified in the balance sheets as current assets. Investments at December
31, 1994 and 1995 consisted of U.S. Treasury bills and certificates of deposit.

     The realized gains and losses on the sale of investments classified as
available for sale are determined using the specific identification method are
included in net income. Unrealized gains/(losses) on securities available for
sale are excluded from earnings and reported in a separate component of
stockholders' equity. There were no material gains or losses either realized or
unrealized for the years ended December 31, 1994, 1995 and 1996.

  INVENTORY

     Inventory consists primarily of dental and office supplies and is stated at
the lower of cost (first-in, first-out) or market.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment are provided using the straight-line method over the
estimated useful lives of the various classes of depreciable assets, ranging
from seven to ten years. Fully depreciated assets are retained in property and
equipment until they are removed from service. Fully depreciated assets as of
December 31, 1994 and 1995 were approximately $1,644,000. Maintenance and
repairs are charged to expenses whereas renewals and major replacements are
capitalized. Gains and losses from dispositions are included in operations.

  INCOME TAXES

     Jules V. Lane, Professional Corporation, and Jules V. Lane, D.D.S. are a
Subchapter S corporation and a sole proprietorship, respectively, and,
accordingly, all federal and state tax liabilities are the responsibility of the
shareholder. Lisadent Corp., a C corporation, is responsible for its own federal
and state tax liabilities.

     Income taxes, including pro forma calculations, are determined under the
liability method. Under this method, deferred taxes are based on the differences
between the financial reporting and tax basis of assets and liabilities and are
measured using the enacted marginal tax rates currently in effect.

  ADVERTISING

     Advertising costs are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of" which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of this standard did not have a material effect on the
Company's financial position, results of operations or cash flows.

3.  COMMITMENTS AND CONTINGENCIES:

  LEASE COMMITMENTS

     The Company leases a portion of its property and equipment under operating
leases. Future minimum lease payments under operating leases with remaining
terms of one or more years consisted of the following at December 31, 1995 (in
thousands):

                                                        OPERATING

                Total minimum obligations............    $ 1,095
                                                        =========

  LITIGATION

     The Company is from time to time subject to claims and suits arising in the
ordinary course of operations. In the opinion of management, the ultimate
resolution of such pending legal proceedings will not have a material effect on
the Company's financial position, results of operations or liquidity.

4.  CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the creditworthiness of
patients and appropriate allowances are made to reduce accounts to their net
realizable values.

     Approximately 55%, 57% and 54% of revenue in 1993, 1994 and 1995,
respectively, was generated from nine payors.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash and cash equivalents, investments, receivables
and accounts payable approximate fair values due to the short-term maturities of
these instruments.

5.  RELATED PARTY TRANSACTIONS:

     The Company paid $249,000, $227,000 and $163,000 in 1993, 1994, and 1995,
respectively to a third party claims administrator wholly-owned by the Company's
stockholders for health and disability insurance claims on behalf of its
employees. The Company also paid $134,000, $109,000 and $107,000 in 1993, 1994
an 1995, respectively, for operating expenses to that insurance company.

     The Company paid $551,000, $598,000 and $555,000 in 1993, 1994 and 1995,
respectively, to a company owned by the Company's stockholders for rent relating
to various dental center locations.

     The Company paid auto, computer and various office equipment rentals of
$69,000, $62,000 and $66,000 in 1993, 1994 and 1995, respectively, to a company
owned by relatives of the stockholders.

     The Company shares certain assets, office space, administrative employees'
services and certain other costs with the various affiliated businesses. The
respective costs were allocated among those businesses based on managements'
determination. Most of such costs are general and administrative in nature. The
Company from time to time has provided and received certain services from
affiliated businesses at no charge. The value of the services received each year
for 1993, 1994 and 1995, exceeded that of services provided by approximately
$100,000 each year.

6.  SUBSEQUENT EVENT:
   
     In September 1996, the Company entered into a definitive agreement with
Castle Dental Centers of New York ("Castle") whereby Castle would acquire
certain assets and liabilities for cash and stock consideration.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholder of
  United DentalCare:

     We have audited the accompanying balance sheet of United DentalCare as of
December 31, 1995, and the related statements of operations, changes in
stockholder's equity and cash flows for each of the two years in the period
ended December 31, 1995. 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 audits.

     We conducted our audits 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 audits provide 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 United DentalCare as of
December 31, 1994 and 1995, and the results of its operations and its cash flows
for each of the two years in the period ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION

     United DentalCare (the "Company"), is a provider of dental services that,
owns and operates dental centers in the south central United States.

     Effective January 1, 1995, the Arkansas Dental Centers were incorporated
under the name United DentalCare. Prior to that date the Company was a sole
proprietorship.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value.

     The Company maintains cash balances at various financial institutions.
Accounts at each institution are insured by the Federal Deposit Insurance
Corporation up to $100,000. The Company's accounts at these institutions may, at
times, exceed the federally insured limits. The Company has not experienced any
losses in such accounts.

  REVENUE RECOGNITION
   
     Net patient revenues represent amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed. Accounts receivable consist primarily of receivables
from patients, insurers, and other third-party payers for dental services
provided by dentists. Such amounts are reduced by an allowance for bad debt
based on historical collection trends.
    
  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
forty years. Maintenance and repairs are charged to expense whereas renewals and
major replacements are capitalized. Gains and losses from dispositions are
included in operations.

  INCOME TAXES

     The Company was a sole proprietorship until January 1, 1995, at which point
it was incorporated and elected Subchapter S status for income tax purposes.
Therefore, all federal and state income tax liabilities are the responsibility
of the shareholder.

  ADVERTISING

     Advertising costs are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for

long-lived assets and certain identifiable intangibles to be disposed of. The
Company adopted SFAS No. 121 during the first quarter of 1996. Implementation of
SFAS No. 121 did not have a material impact on its financial position, results
of operations or cash flows.

5.  SUPPLEMENTAL CASH FLOW INFORMATION:

                                              DECEMBER 31,

Transfer of buildings and related notes
  payable to sole proprietor............         --        136

6.  CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the creditworthiness of
patients and appropriate allowances are made to reduce accounts to their net
realizable values.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, receivables and accounts
payable approximate fair values due to the short-term maturities of these
instruments. The carrying amounts of the Company's long-term borrowings as of
December 31, 1994 and 1995, respectively, approximate their fair value.

     The carrying value of the Company's revolving credit agreement approximates
fair value because the rate on such agreement is variable, based on current
market.

7.  SUBSEQUENT EVENTS:

     During 1996, the Company purchased the assets of a dental practice in
Oklahoma for total consideration of approximately $238,000.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

     During June 1996, the Company entered into a letter of intent with Castle
Dental Centers of Arkansas ("Castle") whereby Castle would acquire certain of
its assets and liabilities for cash and stock consideration.

8.  RELATED PARTY TRANSACTIONS:

     The Company has set up an entity owned by its sole shareholder to act as
its advertising agency. The Company purchased advertising services of
approximately $44,000 and $139,000, respectively, for 1994 and 1995.

                         NOTES TO FINANCIAL STATEMENTS

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  CORPORATE ORGANIZATION

     Southwest Dental Associates (the "Company") is a provider of dental and
orthodontics services and products that owns and operates dental centers in the
Austin, Texas area.

     The statements reflect the operations of Southwest Dental Associates, L.C.

  USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during each
reporting period. Actual results could differ from those estimates.

  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid debt investments with original
maturities of three months or less when purchased to be cash equivalents. The
carrying amounts approximate fair value because of the short maturity.

     The Company maintains cash balances at financial institutions. Accounts at
each institution are insured by the Federal Deposit Insurance Corporation up to
$100,000. The Company's accounts at these institutions may, at times, exceed the
federally insured limits. The Company has not experienced any losses in such
accounts.

  REVENUE RECOGNITION

     Net patient revenue represents amounts billed to patients for services
performed by affiliated dentists. Dental revenue is recognized as the services
are performed and billed.

     Accounts receivable primarily consist of receivables from patients,
insurers, government programs and other third-party payers for services provided
by dentists. An allowance for doubtful accounts is recorded by the Company based
on historical experience.

  PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization of
property and equipment, which include the amortization of assets recorded under
capital leases, are provided using the straight-line method over the estimated
useful lives of the various classes of depreciable assets, ranging from five to
ten years. Maintenance and repairs are charged to expenses whereas renewals and
major replacements are capitalized. Gains and losses from dispositions are
included in operations.

  INCOME TAXES

     The Company is a limited liability corporation and, accordingly, all
federal and state tax liabilities are the responsibility of the respective
shareholders.

     Income taxes for the pro forma calculation are determined under the
liability method. Under this method, deferred taxes are based on the differences
between the financial reporting and tax basis of assets and liabilities and are
measured using the enacted marginal tax rates currently in effect.

  ADVERTISING

     Advertising costs are expensed when incurred.

  RECENT FASB PRONOUNCEMENTS

     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121 "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles and goodwill related to those assets to
be held and used, and for long-lived assets and certain identifiable intangibles
to be disposed of. The Company adopted SFAS No. 121 during the first quarter of
1996. Implementation of this standard did not have a material effect on the
Company's financial position, results of operations or cash flows.

7.  CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

  CREDIT RISK

     The Company grants patients credit in the normal course of business. The
credit risk with respect to these patient receivables is generally considered
minimal because procedures are in effect to monitor the credit worthiness of
patients and appropriate allowances are made to reduce accounts to their net
realizable values.

  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The following estimated fair values of financial instruments have been
determined by the Company using available market information and appropriate
valuation methodologies.

     The carrying amounts of cash and cash equivalents, patient receivables and
accounts payable approximate fair values due to the short-term maturities of
these instruments. The carrying amounts of the Company's fixed rate long-term
borrowings as of December 31, 1995, approximate their fair value.

8.  RELATED PARTY TRANSACTIONS:
     The Company leased certain assets from a relative of the stockholders.
These leases were recorded as capital leases. At December 31, 1995, the balance
of capital lease obligations was approximately $220,000.
     The Company had a note payable outstanding with a relative of the
stockholders. The balance of the note payable at December 31, 1995 was
approximately $10,000.

9.  SUBSEQUENT EVENT:

     During September 1996, the Company entered into a definitive agreement with
Castle Dental Centers of Texas ("Castle") whereby Castle would acquire certain
assets and liabilities for cash and stock consideration.

1.  ORGANIZATION AND BASIS OF PRESENTATION:

  ORGANIZATION

     Castle Dental Centers, Inc. and subsidiaries (the "Company") provide
management systems and services, non-healthcare personnel, facilities and
equipment to certain professional corporations under long-term management
service agreements. These professional corporations are collectively referred to
as the Affiliated Dental Practices.

     The Company has entered into a long-term management services agreement with
each of the Affiliated Dental Practices, under which the Company provides
substantially all administrative and management services, in exchange for a
predetermined management fee. Each of these agreements is a 40-year agreement
with successive automatic five-year renewal terms between the Company and its
Affiliated Dental Practices unless terminated at least 90 days before the end of
the initial term or any renewal term.
   
     Through the management services agreement, the Company assumes full
responsibility for the operating expenses, has the right to purchase and has
responsibility for collection of all accounts receivable and receives a
management fee for providing non-dental services. The Company has perpetual,
unilateral control over the assets and operations of the Affiliated Dental
Practices (except with respect to those relating to the practice of dentistry
and other matters requiring licensure). Notwithstanding the lack of technical
majority ownership of the stock of such entities, consolidation of the
Affiliated Dental Practices is necessary to present fairly the financial
position and results of operations of the Company because of control by means
other than ownership of stock. Control by the Company will be perpetual rather
than temporary because of (i) the length of the original terms of the
agreements, (ii) the successive extension periods provided by the agreements,
(iii) the continuing investment of capital by the Company, (iv) the employment
of the majority of the nonprofessional personnel, and (v) the nature of the
services provided to the Affiliated Dental Practices by the Company.
    
  BASIS OF PRESENTATION

     The accompanying unaudited condensed consolidated financial statements as
of June 30, 1996 and for the six months ended June 30, 1995 and 1996 include the
accounts of the Company, its wholly-owned subsidiaries and the Affiliated Dental
Practices. They have been prepared by the Company pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in annual financial statements prepared
in accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations. These unaudited condensed consolidated
financial statements should be read in conjunction with the annual combined
financial statements of the Company included elsewhere, herein. In management's
opinion, such interim financial statements include all normal recurring
adjustments considered necessary for a fair presentation of such financial
statements. Interim results are not necessarily indicative of results for a full
year.

  INTANGIBLE ASSETS

     Intangible assets consist primarily of goodwill and debt issuance costs.
   
     Goodwill represents the excess of the purchase price over the fair value of
identifiable net assets acquired and is amortized on a straight-line basis over
the terms of the management services agreements of 40 years. At each balance
sheet date the Company assesses the recoverability of goodwill and whether a
change in circumstances has occurred subsequent to an acquisition which would
indicate whether the future useful life of an asset should be revised. The
Company employs a systematic and rational method of assessing the recoverability
of goodwill by considering various factors such as the estimated future
undiscounted cash flows associated with the acquired business, the earnings
potential of acquired business, the management fees generated under the related
management services agreement, the value of the revenue stream generated under
any related managed care contracts and the strategic value of the office
location acquired or assumed as a result of the acquisition as compared to the
carrying value of the goodwill.

2.  EARNINGS PER SHARE:

     Earnings per share is computed on the basis of the weighted average number
of shares of common stock and common stock equivalents outstanding during each
period. Shares outstanding for all periods presented have been retroactively
adjusted to reflect the reorganization discussed in the annual financial
statements. In accordance with Staff Accounting Bulletin ("SAB") Number 83 of
the Securities and Exchange Commission, the common stock equivalents that were
issued during the twelve months preceding the planned offering at prices below
the expected initial public offering price have been included in the Company's
earnings per share computation and treated as if they had been issued at the
Company's inception event though they were antidilutive. Additionally, in
accordance with SAB Number 55, pro forma earnings per share have been presented
for 1995 to reflect issuance of the number of shares that would have been
necessary to fund the $6,000,000 distribution to the Company's owner in
connection with the Reorganization (at an assumed public offering price of
$10.00 per share). Fully diluted earnings per share are not presented because
such amounts would be the same as amounts computed for primary earnings per
share.

3.  ACQUISITIONS:

     The Company acquired the assets of 1st Dental Care and Mid-South Dental
Centers during May 1996 for combined purchase prices of $12,748. The purchase
prices consisted primarily of combinations of cash, common stock and debt
issued. The excess of the purchase prices over the fair value of net assets
acquired is included in goodwill. In connection with these acquisitions, the
Company entered into customary employment agreements with certain employees and
former owners of the businesses acquired and entered into a long-term management
services agreement with each physician practice.

     The following represents the unaudited pro forma results of operations as
if all of the above noted business combinations had occurred at the beginning of
1995:

Company's results of operations or financial condition had the acquisitions been
consummated on the dates indicated and are not intended to project the Company's
results of operations or financial condition for any future period or as of any
future date.

4.  LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS:

     Long-term debt and capital lease obligations consisted of the following at
June 30, 1996 (dollars in thousands):
   
Subordinated notes......................  $   7,500
Term loan...............................      9,950

      lease obligations.................  $  15,558
                                          =========
    
     On May 31, 1996, the Company entered into an Amended and Restated Credit
Agreement with NationsBank, which increased the term loan facility to $16.0
million. The additional $10 million is to be utilized to fund acquisitions,
which are subject to prior approval by NationsBank. As of June 30, 1996, the
Company had borrowed $3,950,000 of this facility to fund the acquisition of
affiliated dental practices based in Nashville, Tennessee and Tampa/Clearwater,
Florida. In August 1996, the Company borrowed an additional $2.1 million under
term loan to fund the acquisition of Horizon Dental Centers in Ft. Worth and
Austin, Texas.
   
     The Company intends to complete an initial public offering during the
fourth quarter of 1996. The proceeds from the offering will be used to repay
approximately $7.5 million of the 12% Subordinated Notes, approximately $6.2
million under the term loan and approximately $4.2 million of seller financed
debt outstanding at June 30, 1996. Pro forma earnings per share would have been
$0.05 for the six months ended June 30, 1996 had the offering proceeds been used
for the retirement of such debt at the beginning of 1996.
    
5.  COMMITMENTS AND CONTINGENCIES:

  LITIGATION

     The Company is subject to claims and suits arising in the ordinary course
of operations. In the opinion of management, the ultimate resolution of such
pending legal proceedings will not have a material effect on the Company's
financial position, results of operations or liquidity.

  DENTIST EMPLOYMENT AGREEMENTS AND PROFESSIONAL LIABILITY

     Each affiliated dental practice has entered into a dentist employment
agreement with each full time dentist, orthodontist and other dental specialist
employed by it. Although the form of contract varies somewhat among practices
and among dentists with different specialties, the typical contract provides for
a defined compensation arrangement, including performance-based compensation,
liquidated damages and a covenant not to compete. Each full time dentist is
required to maintain professional liability insurance, and mandated coverage
limits are generally at least $1,000,000 per claim and $1,000,000 in aggregate.
In addition, many affiliated dental practices employ part time dentists. Not all
part time dentists have employment agreements, but all part time dentists are
required to carry professional liability insurance in specified amounts.

6.  STOCK OPTION PLANS

     Through June 30, 1996, the Company had granted options for 380,500 shares
of common stock under its employee stock option plan at prices per share ranging
from $5.00 to $6.75. Generally, the outstanding

                                      F-78
<PAGE>
                          CASTLE DENTAL CENTERS, INC.
      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                                  (UNAUDITED)
options are exercisable one year from the date of grant as to 20% of the
underlying shares, and as to an additional 20% on each of the next four
anniversaries of the date of option grant.

     In August 1996, the Company adopted a non-employee directors' stock option
plan to encourage ownership of common stock by eligible non-employee directors
(the "Directors' Plan"). The Directors' Plan provides for the automatic grant
of 25,000 nonqualified stock options (the "Options") to non-employee directors
at the time they become directors.

     All non-employee directors are eligible to receive options under the
Directors' Plan. Options will be exercisable during a ten-year period from the
date of grant of the options and will vest based upon the number of full years
of service a non-employee director serves on the Board of Directors as follows:
20% after one full year of service, 40% after two full years of service, 60%
after three full years of service, 80% after four full years of service and 100%
after five full years of service. No option will remain exercisable later than
ten years after the date of grant.

     The exercise price for options granted under the Directors' Plan may be no
less than the fair market value of the common stock on the date of grant.

7.  EMPLOYEE RETIREMENT PLAN

     In August 1996, the Company adopted a profit sharing plan qualified under
Section 401(k) of the Internal Revenue Code of 1986 (the "401(k) Plan"). All
employees of the Company are eligible to participate in the 401(k) Plan upon the
completion of six months of service. Participants may elect to defer receipt of
compensation and have such deferred amounts contributed to the 401(k) Plan up to
a maximum of 20% of compensation. The Company may match contributions made by
participants under the 401(k) Plan each year in an amount determined by the
Company on a year-to-year basis. Participants are fully vested with respect to
their contributions, while the Company's contributions are subject to vesting on
the following basis: zero for fewer than two years of employment and 20% per
year cumulatively for the third through seventh years of employment.
Participants may borrow from their accounts under the 401(k) Plan.

8.  SUBSEQUENT EVENTS:
   
     In August 1996, the Company acquired the assets of certain dental practices
and the stock of others operated by Horizon Dental Centers ("Horizon"), a
dental practice with dental centers in Fort Worth and Austin, Texas. It
concurrently entered into a management services agreement with Horizon Dental
Centers. The Company has entered into definitive agreements to acquire the
assets of and enter into long-term management services agreements with American
Dental Centers, a dental practice based in Hicksville, New York with dental
centers in the New York City area, and United Dental Care, a dental practice
based in Little Rock, Arkansas that operates dental centers in Arkansas,
Oklahoma and Louisiana.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     The Company's Certificate of Incorporation, as amended, and Bylaws
incorporate substantially the provisions of the Delaware General Corporation Law
("DGCL") providing for indemnification of directors and officers of the
Company against expenses, judgments, fines, settlements and other amounts
actually and reasonably incurred in connection with any proceeding arising by
reason of the fact that such person is or was an officer or director of the
Company or is or was serving at the request of the Company as a director,
officer or employee of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise.

     As permitted by Section 102 of the DGCL, the Company's Certificate of
Incorporation, as amended, contains provisions eliminating a director's personal
liability for monetary damages to the Company and its stockholders arising from
a breach of a director's fiduciary duty except for liability (a) for any breach
of the director's duty of loyalty to the Company or its stockholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the DGCL, or (d) for any
transaction from which the director derived an improper personal benefit.

     Section 145 of the DGCL provides generally that a person sued as a
director, officer, employee or agent of a corporation may be indemnified by the
corporation for reasonable expenses, including attorneys' fees, if in the case
of other than derivative suits such person has acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation (and, in the case of a criminal proceeding, had no
reasonable cause to believe that such person's conduct was unlawful). In the
case of a derivative suit, an officer, employee or agent of the corporation
which is not protected by the Certificate of Incorporation may be indemnified by
the corporation for reasonable expenses, including attorneys' fees, if such
person has acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation, except that no
indemnification shall be made in the case of a derivative suit in respect of any
claim as to which an officer, employee or agent has been adjudged to be liable
to the corporation unless that person is fairly and reasonably entitled to
indemnity for proper expenses. Indemnification is mandatory in the case of a
director, officer, employee, or agent who is successful on the merits in defense
of a suit against such person.

     The Company has entered into Indemnity Agreements with its directors and
certain key officers pursuant to which the Company generally is obligated to
indemnify its directors and such officers to the full extent permitted by the
DGCL as described above.

                                      II-1

     The Company intends to purchase liability insurance policies covering

 + Exhibit omits certain information which the Company has filed separately with
   the Commission pursuant to a confidential treatment request under Rule 406
   promulgated under the Securities Act of 1933, as amended.

ITEM 17.  UNDERTAKINGS.

     (a)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the provisions described in Item 14, or otherwise,
the Company has been advised that in the opinion of the Commission such
indemnification is 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 payment by the Company of expenses incurred
or paid by a director, officer or controlling person of the Company 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 Company 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.

     (b)  The undersigned registrant hereby undertakes to provide to the
underwriter at the closing specified in the underwriting agreement certificates
in such denominations and registered in such names as required by the
underwriter to permit prompt delivery to each purchaser.

     (c)  The undersigned registrant hereby undertakes that: (i) for purposes of
determining any liability under the Securities Act of 1933, 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; (ii) for the purpose of determining any liability under the
Securities Act of 1933, 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.

                         REGISTRATION RIGHTS AGREEMENT

      REGISTRATION RIGHTS AGREEMENT, dated as of _______________, 1996 (the
"Agreement"), by and between CASTLE DENTAL CENTERS, INC., a Delaware corporation
(the "Company"), and ____________________ (the "Holder").

      1. INTRODUCTION. Contemporaneously with the execution and delivery of this
Agreement, the Holder acquired an aggregate of ________ shares of the common
stock, $.001 par value per share, of the Company (the "Common Stock"). The
Company has agreed to grant to the Holder certain registration rights with
respect to the shares of Common Stock held by the Holder as more fully set forth
herein. Prior to the date hereof, the Company entered into a Registration Rights
Agreement dated as of December 18, 1995, with purchasers of the Company's Series
A Convertible Preferred Stock and certain other parties, as may be amended from
time to time (the "Original Registration Rights Agreement"), and other
agreements regarding registration of Common Stock with other parties. Certain
terms used herein which are not otherwise defined are defined in the Original
Registration Rights Agreement.

      2. REGISTRATION UNDER SECURITIES ACT.

            2.1   "PIGGYBACK" REGISTRATIONS.

                  (a) RIGHT TO INCLUDE HOLDER SECURITIES. If the Company at any
time proposes to register any Common Stock under the Securities Act (other than
by a registration on Form S-4, Form S-8 or any successor or similar form, or in
connection with a tender offer, merger, or other acquisition in which no shares
are offered or sold to the general public), for sale for its own account, and
such Common Stock is to be distributed by or through one or more underwriters on
a firm commitment basis, it will at such time give prompt written notice to all
Holders of Holder Securities (as hereinafter defined) of its intention to do so
and of such Holders' rights under this Section 2.1. Upon the written request of
any such Holder made within 20 days after the date of any such notice given in
accordance with Section 7 hereof, the Company will use its best efforts to
effect the registration under the Securities Act of all Holder Securities which
the Company has been so
<PAGE>
requested to register by the Holders thereof, and to arrange for such
underwriters to include all the Holder Securities to be offered and sold by such
Holder among the Common Stock to be distributed by such underwriters, PROVIDED
that if, at any time after giving written notice of its intention to register
its Common Stock and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register or to delay registration of its Common Stock, the Company
may, at its election, give written notice of such determination to each Holder
of Holder Securities and, thereupon, (i) in the case of a determination not to
register, shall be relieved of its obligation to register any Holder Securities
in connection with such registration (but not from its obligation to pay the
Registration Expenses in connection therewith), and (ii) in the case of a
determination to delay registering, shall be permitted to delay registering any
Holder Securities for the same period as the delay in registering its Common
Stock. The Holders of Holder Securities to be distributed by such underwriters
shall be parties to the underwriting agreement between the Company and such
underwriters. Any such Holder of Holder Securities shall not be required to make
any representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties, or agreements typical in an
offering of this type, including those regarding such Holder, such Holder's
Holder Securities and such Holder's intended method of distribution, any other
information supplied by such Holder to the Company for use in the registration
statement and any other representation required by law. The Company will pay all
Registration Expenses in connection with each registration of Holder Securities
requested pursuant to this Section 2.1.

                  (b) APPORTIONMENT IN "PIGGYBACK" REGISTRATIONS. If the
managing underwriter of such underwritten offering shall inform the Company and
the Holders of the Holder Securities requesting such registration in writing of
its belief that the aggregate number of shares of Common Stock requested to be
included in such registration (including any securities of other securityholders
of the Company included in such registration pursuant to the terms of the
Original Registration Rights Agreement) exceeds the number which can be sold in
(or during the time of) such offering or that the inclusion would adversely
affect the marketing or the selling price of the Common Stock to be sold by the
Company therein, then the Company may include all securities proposed by the
Company to be sold for its own account and may decrease or eliminate the number
of Holder Securities requested to be included in such registration to the extent
necessary to reduce the number of shares of Common Stock to be included in the
registration to the level recommended by the managing underwriter. In the event
that such a reduction is necessary, the number of Holder Securities to be
included in such registration shall be reduced, on a pro rata basis among
Holders (based on the total number of shares of Common Stock owned by Holders
and other parties (but excluding for purposes of this calculation Common Stock
which constitutes Registrable Inside Shareholder Securities and Registrable
Securities) and requested to be included in such registration), prior to any
reduction in the number of Registrable Inside Shareholder Securities and
Registrable Securities to be included in such registration.

            2.2 REGISTRATION PROCEDURES. If and whenever the Company is required
to use its best efforts to effect the registration of any Holder Securities
under the Securities Act as provided in Section 2.1, the Company will as
expeditiously as possible:

                        (i) prepare and file with the Commission the requisite
      registration statement to effect such registration and thereafter use its
      best efforts to cause such registration statement to become effective,
      PROVIDED that the Company may discontinue any registration of its
      securities at any time prior to the effective date of the registration
      statement relating thereto;

                        (ii) prepare and file with the Commission such
      amendments and supplements to such registration statement and the
      prospectus used in connection therewith as may be necessary to keep such
      registration statement effective and to comply with the provisions of the
      Securities Act with respect to the disposition of all securities covered
      by such registration statement until such time as all of such securities
      have been disposed of in accordance with the intended methods of
      disposition by the seller or sellers thereof set forth in such
      registration statement or for six months, whichever period is shorter;

                        (iii) furnish to each seller of Holder Securities
      covered by such registration statement such number of conformed copies of
      such registration statement and of each such amendment and supplement
      thereto, such number of copies of the prospectus contained in such
      registration statement (including each preliminary prospectus and any
      summary prospectus) and any other prospectus filed under Rule 424 or Rule
      430A under the Securities Act, in conformity with the requirements of the
      Securities Act, and such other documents, as such seller may reasonably
      request;

                        (iv) use its best efforts to register or qualify all
      Holder Securities covered by such registration statement under such other
      securities or blue sky laws of such jurisdictions as each seller thereof
      shall reasonably request, to keep such registration or qualification in
      effect for so long as such registration statement remains in effect, and
      take any other action which may be reasonably necessary to enable such
      seller to consummate the disposition in such jurisdictions of the
      securities owned by such seller, except that the Company shall not for any
      such purpose be required to qualify generally to do business as a foreign
      corporation in any jurisdiction wherein it would not but for the
      requirements of this subdivision (iv) be obligated to be so qualified or
      to consent to general service of process in any such jurisdiction or
      subject itself to be required to pay any franchise or income taxes in any
      such jurisdiction;

                                    -3-
<PAGE>
                        (v) use its best efforts to cause all Holder Securities
      covered by such registration statement to be registered with or approved
      by such other governmental agencies or authorities as may be necessary to
      enable the seller or sellers thereof to consummate the disposition of such
      Holder Securities;

                        (vi) furnish to each seller of Holder Securities a
      signed counterpart, addressed to such seller, of:

                              (x) an opinion of counsel for the Company, dated
            the date of the closing under the underwriting agreement, reasonably
            satisfactory in form and substance to such underwriter, and

                              (y) a "comfort" letter, dated the effective date
            of such registration statement and dated the date of the closing
            under the underwriting agreement, signed by the independent public
            accountants who have certified the Company's financial statements
            included in such registration statement, addressed to each seller,
            to the extent the same can be reasonably obtained, and addressed to
            the underwriters, covering substantially the same matters with
            respect to such registration statement (and the prospectus included
            therein) and, in the case of the accountants' letter, with respect
            to events subsequent to the date of such financial statements, as
            are customarily covered in accountants' letters delivered to the
            underwriters in underwritten public offerings of securities and such
            other financial matters as such seller or the underwriters may
            reasonably request;

                        (vii) notify each seller of Holder Securities covered by
      such registration statement, at any time when a prospectus relating
      thereto is required to be delivered under the Securities Act, upon
      discovery that, or upon the happening of any event as a result of which,
      the prospectus included in such registration statement, as then in effect,
      includes an untrue statement of a material fact or omits to state any
      material fact required to be stated therein or necessary to make the
      statements therein not misleading in the light of the circumstances under
      which they were made, and at the request of any such seller or holder
      promptly prepare to furnish to such seller or Holder a reasonable number
      of copies of a supplement to or an amendment of such prospectus as may be
      necessary so that, as thereafter delivered to the sellers of such
      securities, such prospectus shall not include an untrue statement of a
      material fact or omit to state a material fact required to be stated
      therein or necessary to make the statements therein not misleading in the
      light of the circumstances under which they were made;

                                    -4-
<PAGE>
                        (viii) otherwise use its best efforts to comply with all
      applicable rules and regulations of the Commission, and make available to
      its security holders, as soon as reasonably practicable, an earnings
      statement covering the period of at least 12 months, but not more than 18
      months, beginning with the first full calendar month after the effective
      date of such registration statement, which earnings statement shall
      satisfy the provisions of Section ll(a) of the Securities Act;

                        (ix) provide and cause to be maintained a transfer agent
      and registrar for all Holder Securities covered by such registration
      statement from and after a date not later than the effective date of such
      registration statement; and

                        (x) use its best efforts to list all Holder Securities
      covered by such registration statement on any securities exchange on which
      any of the Company's Common Stock is then listed.

            The Company may require each proposed seller of Holder Securities as
to which any registration is being effected to promptly furnish the Company, as
a condition precedent to including such Holder's Holder Securities in any
registration, such information regarding such seller and the distribution of
such securities as the Company may from time to time reasonably request in
writing.

            Each Holder of Holder Securities agrees by acquisition of such
Holder Securities that upon receipt of any notice from the Company of the
happening of any event of the kind described in subdivision (vii) of this
Section 2.2, such Holder will forthwith discontinue its disposition of Holder
Securities pursuant to the registration statement relating to such Holder
Securities until such Holder's receipt of the copies of the supplemented or
amended prospectus contemplated by subdivision (vii) of this Section 2.2 and, if
so directed by the Company, will deliver to the Company (at the Company's
expense) all copies, other than permanent file copies, then in such Holder's
possession of the prospectus relating to such Holder Securities current at the
time of receipt of such notice.

            2.3 PREPARATION; REASONABLE INVESTIGATION. In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the Holders of Holder
Securities registered under such registration statement, their underwriters, if
any, and their respective counsel (such counsel representing Holders to be
appointed by the holders of more than 50% by number of shares of Common Stock
being registered other than shares being registered by the Company) the
opportunity to participate in the preparation of such registration statement,
each prospectus included therein or filed with the Commission, and each
amendment thereof or supplement thereto, and will give each of them such access
to its books and records and such opportunities to discuss the business of the
Company with its officers and the

                                    -5-
<PAGE>
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such Holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

            2.4   INDEMNIFICATION.

                  (a) INDEMNIFICATION BY THE COMPANY. In the event of any
registration of any securities of the Company under the Securities Act, the
Company will indemnify and hold harmless the seller of any Holder Securities
covered by such registration statement, its directors and officers, each other
Person, if any, who controls such seller within the meaning of the Securities
Act, against any losses, claims, damages, expenses or liabilities, joint or
several, to which such seller or any such director or officer or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages, expenses or liabilities (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in any registration statement under which such securities were
registered under the Securities Act, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and the Company will reimburse such seller and each such
director, officer and controlling person for any legal or any other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, liability, action or proceeding; PROVIDED, HOWEVER, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage, expense or liability arises out of or is based upon (a) an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, said preliminary or final prospectus or said
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
seller, specifically for use in the preparation thereof or (b) an untrue
statement or alleged untrue statement, omission or alleged omission in a
prospectus if such untrue statement or alleged untrue statement, omission or
alleged omission is corrected in an amendment or supplement to the prospectus or
in the final prospectus, which amendment, supplement or final prospectus is
delivered to such seller and such seller thereafter fails to deliver such
prospectus as so amended or supplemented prior to or concurrently with the sale
of registered Holder Securities to the person asserting such loss, claim,
damage, liability or expense. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such seller or
any such director, officer or controlling person and shall survive the transfer
of such securities by such seller.

                  (b) INDEMNIFICATION BY THE HOLDERS. The Holders will, and
hereby do, indemnify and hold harmless (in the same manner and to the same
extent as set forth in subdivision

                                    -6-
<PAGE>
(a) of this Section 2.4) the Company, each director of the Company, each officer
of the Company and each other Person, if any, who controls the Company within
the meaning of the Securities Act with respect to any statement or alleged
statement in or omission or alleged omission from such registration statement,
any preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, if such statement or alleged
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Holder for
use in the preparation of such registration statement, preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement. Such indemnity
shall remain in full force and effect, regardless of any investigation made by
or on behalf of the Company or any such director, officer or controlling Person
and shall survive the transfer of such securities by such Holder.

                  (c) NOTICE. Promptly after receipt by an indemnified party of
notice of the commencement of any action or proceeding involving a claim
referred to in the preceding subdivisions of this Section 2.4, such indemnified
party will, if a claim in respect thereof is to be made against an indemnifying
party, give written notice to the latter of the commencement of such action,
PROVIDED that the failure of any indemnified party to give notice as provided
herein shall not relieve the indemnifying party of its obligations under the
preceding subdivisions of this Section 2.4, except to the extent that the
indemnifying party is prejudiced by such failure to give notice. In case any
such action is brought against an indemnified party, unless in such indemnified
party's reasonable judgment a conflict of interest between such indemnified
party and indemnifying parties may exist in respect of such claim, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, jointly with any other indemnifying party similarly notified to the
extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the consent of the indemnified party, consent to entry of
any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

                  (d) INDEMNIFICATION PAYMENTS. The indemnification required by
this Section 2.4 shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, as and when bills are received or
expense, loss, damage or liability is incurred.

            2.5 ADJUSTMENTS AFFECTING HOLDER SECURITIES. The Company will not
effect or permit to occur any combination or subdivision of shares which would
adversely affect the ability

                                    -7-

of the holders of Holder Securities to include such Holder Securities in any

Purchaser for breaches of those representations and warranties. Such review
shall occur only during normal business hours upon reasonable notice by
Purchaser and in a manner which will not interfere with the day-to-day operation
of the Business, except to the limited extent necessary to comply with due
diligence requests and updates. Seller and the Shareholders shall permit

its discovery of facts giving rise to a claim for indemnity under the provisions
of this Agreement, including receipt by it of notice of any demand, assertion,
claim, action or proceeding, judicial or otherwise, by any third party (such
third party actions being collectively referred to herein as the "Claim"), with
respect to any matter as to which it claims to be entitled to indemnity under
the provisions of this Agreement, it will give prompt notice thereof in writing
to the indemnifying party, together with a statement of such information
respecting any of the foregoing as it shall have. Such notice shall include a
formal demand for indemnification under this Agreement. The indemnifying party
shall not be obligated to indemnify the indemnified party with respect to any
Claim if the indemnified party knowingly failed to notify the indemnifying party
thereof within three business days of the 

                                     - 38 -
<PAGE>
receipt of the Claim, if such failure to notify prevented the indemnifying party
or its counsel from defending against such matter and making a timely response
thereto including, without limitation, any responsive motion or answer to a
complaint, petition, notice or other legal, equitable or administrative process
relating to the Claim, but only insofar as such knowing failure to notify the
indemnifying party actually resulted in prejudice or damage to the indemnifying
party.

      11.4 RIGHT TO CONTEST AND DEFEND. The indemnifying party shall be entitled
at its cost and expense to contest and defend by all appropriate legal
proceedings any Claim with respect to which it is called upon to indemnify the
indemnified party under the provisions of this Agreement; provided, that notice
of the intention so to contest shall be delivered by the indemnifying party to
the indemnified party within 20 days from the date of receipt by the
indemnifying party of notice by the indemnified party of the assertion of the
Claim. Any such contest may be conducted in the name and on behalf of the
indemnifying party or the indemnified party as may be appropriate. Such contest
shall be conducted by reputable counsel employed by the indemnifying party, but
the indemnified party shall have the right but not the obligation to participate
in such proceedings and to be represented by counsel of its own choosing at its
sole cost and expense. The indemnifying party shall have full authority to
determine all action to be taken with respect thereto; provided, however, that
the indemnifying party will not have the authority to subject the indemnified
party to any obligation whatsoever, other than the performance of purely
ministerial tasks or obligations not involving material expense, and in no event
shall any party be required to admit to professional negligence. If the
indemnifying party does not elect to contest any such Claim, the indemnifying
party shall be bound by the result obtained with respect thereto by the
indemnified party. At any time after the commencement of the defense of any
Claim, the indemnifying party may request the indemnified party to agree in
writing to the abandonment of such contest or to the payment or compromise by
the indemnified party of the asserted Claim, whereupon such action shall be
taken unless the indemnified party determines that the contest should be
continued, and so notifies the indemnifying party in writing within 15 days of
such request from the indemnifying party. If the indemnified party determines
that the contest should be continued, the indemnifying party shall be liable

                      appropriate tax returns and reports required of PC.

               (2)    SALES AND USE TAXES. Business Manager and PC acknowledge
                      and agree that to the extent that any of the services to

                      to any State sales and use taxes, Business Manager may
                      have a legal obligation to collect such taxes from PC and
                      to remit same to the appropriate tax collection
                      authorities. PC agrees to pay in addition to the payment

                           ARTICLE V. COVENANTS OF PC

        Section 5.1 ORGANIZATION AND OPERATION. PC, as a continuing condition of
Business Manager's obligations under this Management Services Agreement, shall
at all times during the Term be and remain legally organized and operated to
provide Dental Services in a manner consistent with all State and federal laws.
PC shall operate and maintain within the Practice Territory a full time practice
of dentistry specializing in the provision of Dental Services.

        Section 5.2 PC PERSONNEL AND SHAREHOLDERS.

        (a) DENTAL PERSONNEL. PC shall retain, as a PC Expense and not as an
Office Expense, that number of Dentists as are reasonably necessary and
appropriate in the sole discretion of PC for the provision of Dental Services.
Each Dentist retained by PC shall hold and maintain a valid and unrestricted
license to practice dentistry in the State, and shall be competent in the
practice of dentistry, including any subspecialties that the retained Dentist
will practice on behalf of PC. PC shall enter into, maintain and enforce with
each such retained Dentist a written employment or other agreement in a form
reasonably satisfactory to PC and Business Manager which will include provisions
that will permit PC to be in compliance with its obligations under Sections 5.6,
5.7 and 5.8, and will not commit and permit to remain outstanding any breach of
such employment or other agreement that would allow the Dentist to terminate for
cause. No such employment or other contract may be amended without the prior
written consent of Business Manager. PC shall be responsible for paying the
compensation and benefits, as applicable, for all Dentists and any other dental
personnel or other contracted or affiliated dentists, and for withholding, as
required by law, any sums for income tax, unemployment insurance, social
security, or any other withholding required by applicable law. Business Manager
may, on behalf of PC, establish and administer the compensation with respect to
such individuals in accordance with the written agreement between PC and each
Dentist. Business Manager shall neither control nor direct any Dentist in the
performance of Dental Services for patients.

        (b) EMPLOYMENT OF NON-DENTIST DENTAL CARE PERSONNEL. PC shall retain as
employees or independent contractors, as an Office Expense, all non-dentist
dental care personnel, such as dental assistants, dental hygienists and dental
technicians, required under the Act or otherwise required by law to work under
the direct supervision of a Dentist or who Business Manager and PC determine
should work under the direct supervision of a Dentist. Such non-dentist dental
care personnel shall be under PC's control, supervision and direction in the
performance of Dental Services for patients.

                                      -17-

        Section 5.3 PROFESSIONAL STANDARDS. As a continuing condition of
Business Manager's obligations hereunder, each Dentist and any other dental
personnel retained by PC to provide Dental Services must (i) comply with, be
controlled and governed by and otherwise provide Dental Services in accordance
with the code of professional conduct and applicable federal, State and
municipal laws, rules, regulations, ordinances and orders, and the ethics and
standard of care of the dental community wherein any Center is located, and (ii)
obtain and retain appropriate dental staff membership with appropriate clinical
privileges at any hospital or health care facility at which Dental Services are
to be provided. Procurement of temporary staff privileges pending the completion
of the dental staff approval process shall satisfy this provision, provided the
Dentist actively pursues full appointment and actually receives full appointment
within a reasonable time.

        Section 5.4 DENTAL SERVICES. PC shall ensure that Dentists and
non-dentist dental care personnel are available to provide Dental Services to
patients. In the event that Dentists are not available to provide Dental
Services coverage, PC shall engage and retain LOCUM TENENS coverage as it deems
reasonable and appropriate based on patient care requirements. Dentists retained
on a LOCUM TENENS basis shall meet all of the requirements of Section 5.3, and
the cost of providing LOCUM TENENS coverage shall be a PC Expense. With the
assistance of the Business Manager, PC and the Dentists shall be responsible for
scheduling Dentist and non-dentist dental care personnel coverage of all dental
procedures. PC shall cause all Dentists to develop and promote PC.

        Section 5.5 PEER REVIEW/QUALITY ASSURANCE. PC shall adopt a peer
review/quality assessment program to monitor and evaluate the quality and
cost-effectiveness of Dental Services provided by dental personnel of PC. Upon
request of PC, Business Manager shall provide administrative assistance to PC in
performing its peer review/quality assurance activities, but only if such
assistance can be provided consistent with maintaining the confidentiality and
nondiscoverability of the processes and actions of the Peer Review/Quality
Assurance process of PC and not be regarded as practicing dentistry under the
Act.

        Section 5.6 PC'S INSURANCE. PC shall, as an Office Expense, obtain and
maintain with commercial carriers acceptable to Business Manager appropriate
worker's compensation coverage for PC's retained personnel, if any, and
professional and comprehensive general liability insurance covering PC. PC shall
use its best efforts to require each of the Dentists PC retains to provide
Dental Services to obtain and maintain professional liability insurance in the
minimum amount of Five Hundred Thousand Dollars ($500,000) for each occurrence
and One Million Five Hundred Thousand Dollars ($1,500,000) annual aggregate,
naming PC as an additional insured. The comprehensive general liability coverage
shall be in the minimum amount of One Million Dollars ($1,000,000) for each
occurrence and Two Million Dollars ($2,000,000) annual aggregate; and
professional

                                      -18-
<PAGE>
liability coverage shall be in the minimum amount of Five Hundred Thousand
Dollars ($500,000) for each occurrence and One Million Five Hundred Thousand
Dollars ($1,500,000) annual aggregate. All insurance policies, including those
obtained by Dentists retained by PC, shall provide for at least thirty (30) days
advance written notice to PC from the insurer as to any alteration of coverage,
cancellation, or proposed cancellation for any cause, and provide that a copy of
such notice be sent to Business Manager. PC and each Dentist retained by PC
shall cause to be issued to Business Manager by such insurer or insurers a
certificate reflecting such coverage and shall provide written notice to
Business Manager promptly upon receipt of notice given to Dentist of the
cancellation or proposed cancellation of such insurance for any cause. Upon the
termination of this Management Services Agreement for any reason, PC shall
obtain and maintain as a PC Expense "tail" professional liability coverage, in
the amounts specified in this section for an extended reporting period of 15
years, and PC shall be responsible for paying all premiums for "tail" insurance
coverage. In no event shall the professional liability insurance carrier be
replaced or changed without PC Consent and Business Manager Consent. PC and
Business Manager agree to use their best efforts to have each other named as
additional insureds on the other's respective professional liability insurance
at Business Manager's expense.

        Section 5.7 CONFIDENTIAL AND PROPRIETARY INFORMATION. PC will not
disclose any Confidential Information of Business Manager without Business
Manager's express written authorization, such Confidential Information will not
be used in any way directly or indirectly detrimental to Business Manager, and
PC will keep such Confidential Information confidential and will ensure that its
affiliates and advisors who have access to such Confidential Information comply
with these nondisclosure obligations; provided, however, that PC may disclose
Confidential Information to those of its Representatives who need to know
Confidential Information for the purposes of this Management Services Agreement,
it being understood and agreed to by PC that such Representatives will be
informed of the confidential nature of the Confidential Information, will agree
to be bound by this Section, and will be directed by PC not to disclose to any
other person any Confidential Information. PC agrees to be responsible for any
breach of this Section by its Representatives. If PC is requested or required
(by oral questions, interrogatories, requests for information or documents,
subpoenas, civil investigative demands, or similar processes) to disclose or
produce any Confidential Information furnished in the course of its dealings
with Business Manager or its affiliates, advisors, or Representatives, PC will
(i) provide Business Manager with prompt notice thereof and copies, if possible,
and, if not, a description, of the Confidential Information requested or
required to be produced so that Business Manager may seek an appropriate
protective order or waive compliance with the provisions of this Section and
(ii) consult with Business Manager as to the advisability of Business Manager's
taking of legally available steps to resist or narrow such request. PC further
agrees that, if in the absence of a protective order or the receipt of a waiver
hereunder PC is nonetheless, in the written

                                      -19-
<PAGE>
opinion of its legal counsel, compelled to disclose or produce Confidential
Information concerning Business Manager to any tribunal or to stand liable for
contempt or suffer other censure or penalty, PC may disclose or produce such
Confidential Information to such tribunal legally authorized to request and
entitled to receive such Confidential Information without liability hereunder;
provided, however, that PC shall give Business Manager written notice of the
Confidential Information to be so disclosed or produced as far in advance of its
disclosure or production as is practicable and shall use its best efforts to
obtain, to the greatest extent practicable, an order or other reliable assurance
that confidential treatment will be accorded to such Confidential Information so
required to be disclosed or produced.

        Section 5.8 NONCOMPETITION. PC hereby recognizes and acknowledges that
Business Manager will incur substantial costs in providing the equipment,
support services, personnel, management, administration, and other items and
services that are the subject matter of this Management Services Agreement and
that in the process of providing services under this Management Services
Agreement, PC will be privy to financial and Confidential Information, to which
PC would not otherwise be exposed. The parties also recognize that the services
to be provided by Business Manager will be feasible only if PC operates an
active practice to which the Dentists associated with PC devote sufficient
professional time and attention. PC agrees and acknowledges that the
noncompetition covenants described hereunder are important for the protection of
Business Manager and that Business Manager would not have entered into this
Management Services Agreement without the possibility of obtaining the following
covenants.

        (a) During the Term of this Management Services Agreement and except for
its obligations pursuant to this Management Services Agreement, PC shall not
establish, operate, or provide Dental Services at a dental office, clinic or
other health care facility anywhere within the Practice Territory.

        (b) Except as specifically agreed to by Business Manager in writing, PC
covenants and agrees that during the Term of this Management Services Agreement
and for a period of five (5) years from the date this Management Services
Agreement is terminated, PC shall not directly or indirectly own (excluding
passive ownership of less than five percent (5%) of the equity of any publicly
traded entity), manage, operate, control, or be otherwise associated with, lend
funds to, lend its name to, or maintain any interest whatsoever in any
enterprise (i) having to do with the provision, distribution, promotion, or
advertising of any type of management or administrative services or products to
third parties in competition with Business Manager, in the Practice Territory;
and/or (ii) offering any type of service(s) or product(s) to third parties
substantially similar to those offered by Business Manager to PC in the Practice
Territory. Notwithstanding the above restriction, nothing herein shall prohibit
PC or any of its shareholders from providing

                                      -20-
<PAGE>
management and administrative services to its or their own dental practices
after the termination of this Management Services Agreement. Moreover, nothing
contained herein shall be construed or interpreted as intending to prohibit a
shareholder of PC form owning and operating AMLI substantially in the manner
presently operated, including but not limited to the negotiation of managed care
and indemnity contracts, which include without limitation, a dual choice option.

        (c) The written employment agreements described in Section 5.2 may
contain covenants of the full-time employees pursuant to which such employees
agree not to compete with PC within the Practice Territory for one (1) year
after termination of the employment agreement in accordance with the terms,
conditions and limitations contained therein.

        (d) PC may obtain formal written agreements from its full-time dentist
employees in the form of Exhibit 5.2(a), pursuant to which such the employees
agree not to compete with PC within the Noncompetition Territory (as defined in
such employment agreements) for one (1) year after termination of the employment
agreement in accordance with the terms, conditions and limitations contained
therein.

        (e) PC understands and acknowledges that the foregoing provisions in
Section 5.7 and Section 5.8, including without limitation the failure to enter
into required contractual relations and to enforce them, are designed to
preserve the goodwill of Business Manager and the goodwill of the individual
Dentists of PC. Accordingly, if PC breaches any obligation of Section 5.7 or
Section 5.8, in addition to any other remedies available under this Management
Services Agreement, at law or in equity, Business Manager shall be entitled to
enforce this Management Services Agreement by injunctive relief and by specific
performance of the Management Services Agreement. Additionally, nothing in this
paragraph shall limit Business Manager's right to recover any other damages to
which it is entitled as result of PC's breach. If any provision of the covenants
is held by a court of competent jurisdiction to be unenforceable due to an
excessive time period, geographic area, or restricted activity, the covenant
shall be reformed to comply with such time period, geographic area, or
restricted activity that would be held enforceable.

        (f) Business Manager acknowledges that the rights of Business Manager in
this Agreement, including without limitation those described in Section 5.8, are
to be enforced solely against PC and not against any officer, director or
shareholder of PC in their individual capacity.

        Section 5.9 NAME, TRADEMARK. PC represents and warrants that, as of the
date hereof, PC conducts its professional practice under the name of, and only
under the name of "American Dental Centers" and that such name has been licensed
to PC by Business Manager. PC covenants and promises that, without the prior
written consent of the Business Manager, PC will not:

<PAGE>
                                           CONFIDENTIAL TREATMENT REQUESTED. THE
                                           REDACTED MATERIAL HAS BEEN SEPARATELY
                                                      FILED WITH THE COMMISSION.

        (a) take any action or omit to take any action that is reasonably likely
to result in the change or loss of the name;

        (b) license, sell, give, or otherwise transfer the name or the right to
use the name to any dental practice, dentist, professional corporation, or any
other entity; or

        (c) cease conducting the professional practice of PC under the name.

        Section 5.10 PEER REVIEW. PC shall designate a committee of Dentists to
function as a dental peer review committee to review credentials of potential
recruits, perform quality assurance functions, and otherwise resolve dental
competence issues. The dental peer review committee shall function pursuant to
formal written policies and procedures.

        Section 5.11 INDEMNIFICATION. PC (but not its officers, directors or
shareholders) shall indemnify, hold harmless and defend Business Manager, its
officers, directors and employees, from and against any and all liability, loss,
damage, claim, causes of action and expenses (including reasonable attorneys'
fees), whether or not covered by insurance, caused or asserted to have been
caused, directly or indirectly, by or as a result of the performance of Dental
Services or any other acts or omissions by PC and/or its shareholders, agents,
employees and/or subcontractors (other than Business Manager) during the term
hereof. Business Manager shall indemnify, hold harmless and defend PC, its
officers, directors and shareholders from and against any and all liability,
loss, damage, claim, causes of action and expenses (including reasonable
attorneys' fees), caused or asserted to have been caused, directly or
indirectly, by or as a result of the performance of any intentional acts,
negligent acts, or omissions by Business Manager and/or its shareholders,
agents, employees and/or subcontractors (other than PC) during the term of this
Agreement.

                        ARTICLE VI. FINANCIAL ARRANGEMENT

        Section 6.1 MANAGEMENT FEE. PC and Business Manager agree that as
compensation to Business Manager for the substantial commitment being made and
to be made by Business Manager hereunder, PC agrees that Business Manager shall
receive as payment for the Management Services performed hereunder (i) the
amount of all Office Expenses paid by the Business Manager on behalf of PC; and
(ii) a Management Fee equal to REDACTED% of the Office Expenses paid by Business
Manger on behalf of PC to cover interest and overhead expenses plus a reasonable
profit. The Management Fee shall be paid in the priority established by Section
4.9(b). PC and Business Manger agree that the fees set forth herein are fair and
reasonable and

                                      -22-
<PAGE>
reflect the fair market value of the services rendered. The obligation to pay
Management Fees is an obligation of PC and not its officers, directors, or
shareholders.

        Section 6.2 SHORTFALLS. If there are not sufficient funds to pay the
Management Fee, all unpaid amounts shall accumulate and carry over from month to
month until paid or until the termination of this Management Services Agreement,
in which case such unpaid amounts shall be immediately due and payable as of the
date of termination. Amounts carried over shall earn interest at the rate of ten
percent (10%) per annum.

        Section 6.3 REASONABLE VALUE. Payment of the Management Fee is not
intended to be and shall not be interpreted or applied as permitting Business
Manager to share in PC's fees for Dental Services or any other services, but is
acknowledged as the parties' negotiated agreement as to the reasonable fair
market value of the equipment, contract analysis and support, other support
services, purchasing, personnel, office space, management, administration,
strategic management and other items and services furnished by Business Manager
pursuant to this Management Services Agreement, considering the nature and
volume of the services required and the risks assumed by Business Manager.

        Section 6.4 PAYMENT OF MANAGEMENT FEE. To facilitate the payment of the
Management Fee as provided in Section 6.1 hereof, PC hereby expressly authorizes
Business Manager to make withdrawals of the Management Fee from the PC Account
in accordance with Section 4.9(b) and as such fee becomes due and payable during
the Term and thereafter as provided in Section 7.3.

        Section 6.5 PERIODIC ADJUSTMENT OF COMPENSATION. The parties hereto
recognize that the Management Services may change in size and scope over the
term of this Management Services Agreement which may necessitate adjusting the
fees provided for herein. Therefore, the parties shall review the compensation
to Business Manager no less frequently than annually. Such review shall consider
the scope of Management Services performed pursuant to this Management Services
Agreement at the time of review, the size and number of facilities being
supplied by the Business Manager, the scope of the services and similar matters.
Any adjustment shall be effective retroactively.

        Section 6.6 ACCOUNTS RECEIVABLE. To assure that PC receives the entire
amount of professional fees for its services and to assist PC in maintaining
reasonable cash flow for the payment of Office Expenses, Business Manager may,
during the Term, purchase, without recourse to PC for the amount of the
purchase, the accounts receivable of PC arising during the previous month by
transferring the amount set forth below into the PC Account. The consideration
for the purchase shall be an amount equal to the Adjusted Gross Revenue recorded
each month (according

                                      -23-
<PAGE>
to GAAP reflecting adjustments related to the bad debt reserve). Business
Manager shall be entitled to offset Office Expenses reimbursement due to
Business Manager under Section 6.2 above against the amount payable for the
accounts receivable. Although it is the intention of the parties that Business
Manager purchase and thereby become the owner of the accounts receivable of PC,
in the event such purchase shall be ineffective for any reason, PC is
concurrently herewith granting to Business Manager a security interest in the
accounts so purchased, and PC shall cooperate with Business Manager and execute
all documents in connection with the pledge of such purchased accounts
receivable to Business Manager. All collections in respect to such accounts
receivable purchased by Business Manager shall be received by Business Manager
as the agent of PC and shall be endorsed to Business Manager and deposited in a
bank account at a bank designated by Business Manager. To the extent PC comes
into possession of any payments in respect of such accounts receivable, PC shall
direct such payments to Business Manager for deposit in bank accounts designated
by Business Manager.

        Section 6.7 DISPUTES REGARDING FEES. PC shall not be entitled to a
set-off or reduction in the Management Fees payable hereunder by reason of its
belief that Business Manager has failed to perform its obligations hereunder or
otherwise.

                        ARTICLE VII. TERM AND TERMINATION

        Section 7.1 INITIAL AND RENEWAL TERM. The Term of this Management
Services Agreement will be for an initial period of forty (40) years after the
effective date, and shall be automatically renewed for successive five (5) year

               (i)    The dissolution of Business Manager or the filing of a
                      petition in voluntary bankruptcy, an assignment for the
                      benefit of creditors, or other action taken voluntarily or
                      involuntarily under any State or federal statute for the
                      protection of debtors;

               (ii)   In the event that Business Manager materially defaults in
                      the performance of any of its material obligations
                      hereunder and such default continues uncured for sixty
                      (60) days after Business Manager receives notice of the
                      default.

Termination by PC hereunder shall require the affirmative vote of three-fourths
of the outstanding voting shares of the common shareholders of PC entitled to
vote. Business Manager shall be given 15 days prior written notice of any such
vote.

        (c) TERMINATION BY AGREEMENT. In the event PC and Business Manager shall
mutually agree in writing, this Management Services Agreement may be terminated
on the date specified in such written agreement.

        (d) LEGISLATIVE, REGULATORY OR ADMINISTRATIVE CHANGE. In the event there
shall be a change in the Act, any federal or State statutes, case laws,
regulations or general instructions, the interpretation of any of the foregoing,
the adoption of new federal or State legislation, or a change in any third party
reimbursement system, any of which are reasonably likely to adversely affect the
manner in which either party may perform or be compensated for its services
under this Management Services Agreement or which shall make this Management
Services Agreement unlawful, the parties shall immediately enter into good faith
negotiations regarding a new service arrangement or basis for compensation for
the services furnished pursuant to this Management Services Agreement that
complies with the law, regulation, or policy and that approximates as closely as
possible the economic position of the parties prior to the change. If good faith
negotiations cannot resolve the matter, it shall be submitted to arbitration as
referenced in Section 8.6; provided however that in the event that the New York
State Board of Dental Examiners issues

                                      -25-
<PAGE>
a final and non-appealable order revoking the license of any Dentist on the
grounds that PC's entering into and performing its obligations under this
Management Services Agreement is unlawful, PC may terminate this Management
Services Agreement upon thirty (30) days prior written notice. In no event
however, may Business Manager and PC be required to rescind this Management
Services Agreement or any other agreement between the parties as the result of
the occurrence of any event described in Section 7.2(d).

        Section 7.3 EFFECTS OF TERMINATION. Upon termination of this Management
Services Agreement, as hereinabove provided, neither party shall have any
further obligations hereunder except for (i) obligations accruing prior to the
date of termination, including, without limitation, payment of the Management
Fees and PC Expenses relating to services provided prior to the termination of
this Management Services Agreement, and (ii) obligations, promises, or covenants
set forth herein that are expressly made to extend beyond the Term, including,
without limitation, the purchase of "tail" insurance as required by Section 5.6,
indemnities, which provisions shall survive the expiration or termination of
this Management Services Agreement for any reason, and noncompetition
provisions, which provisions shall survive the expiration or termination of this
Management Services Agreement by Business Manager for cause or by PC in breach
of this Agreement. In effectuating the provisions of this Section 7.3, PC
specifically acknowledges and agrees that Business Manager shall continue to
collect and receive on behalf of PC all cash collections from accounts
receivable in existence at the time this Management Services Agreement is
terminated, it being understood that such cash collections will represent, in
part, compensation to Business Manager for management services already rendered
and compensation on accounts receivable purchased by Business Manager. Upon the
expiration or termination of this Management Services Agreement for any reason
or cause whatsoever, Business Manager shall surrender to PC all books and
records pertaining to PC's dental practice.

prescription or administration of drugs shall be the sole responsibility of PC
and its Dentists, and Business Manager shall not interfere in any manner or to
any extent therewith. Nothing contained in this Management Services Agreement

nondental management and administrative services to PC so as to enable PC to
devote its full time

                                      -26-

or joint venture relationship, or to allow either to exercise control or
direction over the manner or method by which the other performs the services
that are the subject matter of this Management Services Agreement or to permit
Business Manager to take any action that would constitute the practice of
dentistry; provided always that the services to be provided hereunder shall be
furnished in a manner consistent with the standards governing such services and
the provisions of this Management Services Agreement. Each party understands and
agrees that (i) the other will not be treated as an employee for federal tax
purposes, (ii) neither will withhold on behalf of the other any sums for income
tax, unemployment insurance, social security, or any other withholding pursuant
to any law or requirement of any governmental body or make available any of the

        Section 8.4 GOVERNING LAW. This Management Services Agreement shall be
governed by the laws of the State of New York applicable to agreements to be
performed wholly within the State. The law of the State was chosen by the
parties after negotiation to govern interpretation of this Management Services
Agreement because New York County, New York is the seat of management for
Business Manager. The federal and State courts of New York County, New York
shall be the exclusive venue for any litigation, special proceeding, or other
proceeding between the parties that may arise out of, or be brought in
connection with or by reason of, this Management Services Agreement.

        Section 8.5 ASSIGNMENT. Except as may be herein specifically provided to
the contrary, this Management Services Agreement shall inure to the benefit of

representatives, successors, and assigns; provided, however, that PC may not
assign this Management Services Agreement without the prior written consent of
Business Manager, which consent may be withheld. The sale, transfer, pledge, or
assignment of any of the common shares held by any shareholder of PC or the
issuance by PC of common or

                                      -28-
<PAGE>
other voting shares to any other person, or any combination of such transactions
within a period of one (1) year, such that the existing shareholder in PC fails
to maintain a majority of the voting interests in PC shall be deemed an
attempted assignment by PC, and shall be null and void unless consented to in
writing by Business Manager prior to any such transfer or issuance. Any breach
of this provision, whether or not void or voidable, shall constitute a material
breach of this Management Services Agreement, and in the event of such breach,
Business Manager may terminate this Management Services Agreement upon
twenty-four (24) hours notice to PC.

        Section 8.6   ARBITRATION.

        (a) GENERAL. The parties shall use good faith negotiation to resolve any
controversy, dispute or disagreement arising out of or relating to this
Management Services Agreement or the breach of this Management Services
Agreement. Any matter not resolved by negotiation shall be submitted to binding
arbitration and such arbitration shall be governed by the terms of this Section
8.6.

        (b) SCOPE. Unless otherwise specifically provided herein, the parties
hereto agree that any claim, controversy, dispute or disagreement between or
among any of the parties hereto arising out of or relating to this Management
Services Agreement (other than claims involving any noncompetition or
confidentiality covenant) shall be governed exclusively by the terms and
provisions of this Section 8.6; provided, however, that the terms and provisions
of this Section 8.6 shall not preclude any party hereto from seeking, or a court
of competent jurisdiction from granting, a temporary restraining order,
temporary injunction or other equitable relief for any breach of (i) any
noncompetition or confidentiality covenant herein or (ii) any duty, obligation,
covenant, representation or warranty, the breach of which may cause irreparable
harm or damage.

        (c) ARBITRATORS. In the event of any claim, controversy, dispute or
disagreement between the parties hereto arising out of or relating to this
Management Services Agreement, and in the further event the parties are unable
to resolve such claim, controversy, dispute or disagreement within thirty (30)
days after notice is first delivered pursuant to Section 8.3, the parties agree
to select arbitrators to hear and decide all such claims under this Section 8.6.
Each party shall select one arbitrator, The two arbitrators so chosen shall then
select a third arbitrator who is experienced in the matter or action that is
subject to such arbitration. If such matter or action involves health-care
issues, then the third arbitrator shall have such qualifications as would
satisfy the requirements of the National Health Lawyers Association Alternative
Dispute Resolution Service. Each of the arbitrators chosen shall be impartial
and independent of all parties hereto. If either of the parties fails to select
an arbitrator within twenty days after the end of such thirty-day period, or if
the arbitrators chosen fail to select a third arbitrator within twenty days,
then any

                                      -29-
<PAGE>
party may in writing request the judge of the United States District Court for
the Southern District of New York senior in term of service to appoint the
arbitrator or arbitrators and, subject to this Section 8.6, such arbitrators
shall hear all arbitration matters arising under this Section 8.6, and, in
default of such selection, may ask the American Arbitration Association.

        (d) APPLICABLE RULES.

        (i)    Each arbitration hearing shall be held at a place in New York,
               New York acceptable to a majority of the arbitrators. The

               Arbitration Rules of the American Arbitration Association to the
               extent such rules do not conflict with the terms hereof. The
               decision of a majority of the arbitrators shall be reduced to
               writing and shall be binding on the parties. Judgment upon the
               award(s) rendered by a majority of the arbitrators may be entered
               and execution had in any court of competent jurisdiction or
               application may be made to such court for a judicial acceptance
               of the award and an order of enforcement. The charges and
               expenses of the arbitrators shall be shared equally by the
               parties to the hearing.

        (ii)   The arbitration shall commence within thirty (30) days after the
               arbitrators are selected in accordance with the provisions of
               this Section 8.6. In fulfilling their duties with respect to the
               matter in arbitration, the arbitrators may consider such matters
               as, in the opinion of the arbitrators, are necessary or helpful
               to make a proper valuation. The arbitrators may consult with and
               engage disinterested third parties to advise the arbitrators. The
               arbitrators shall not add any interest factor reflecting the time
               value of money to the amount of any award granted under any
               arbitration hereunder and shall not award any punitive damages.

        (iii)  In no event may the decision of the arbitrators (a) require
               recision of the transactions contemplated by this Management
               Services Agreement or the Asset Purchase Agreement dated as of
               August ___, 1996, to which PC and Business Manager are parties,
               or (b) provide for the payment of damages by PC in excess of the
               assets of PC that it acquires after the date of execution of this
               Management Services Agreement.

        (iv)   If any of the arbitrators selected hereunder should die, resign
               or be unable to perform his or her duties hereunder, the
               remaining arbitrators or such senior judge (or such judge's
               successor) shall select a replacement arbitrator. The procedure

                                      -30-
<PAGE>
               set forth in this Section 8.6 for selecting the arbitrators shall
               be followed from time to time as necessary.

        (v)    As to the resolution of any claim, controversy, dispute or
               disagreement that under the terms hereof is made subject to
               arbitration, no lawsuit based on such resolution shall be
               instituted by either of the parties hereto, other than to compel
               arbitration proceedings or enforce the award of a majority of the
               arbitrators.

        (vi)   All privileges under New York and federal law, including
               attorney-client and work-product privileges, shall be preserved
               and protected to the same extent that such privileges would be
               protected in a federal court proceeding applying New York law.

        Section 8.7 WAIVER OF BREACH. The waiver by either party of a breach or
violation of any provision of this Management Services Agreement shall not
operate as, or be construed to constitute, a waiver of any subsequent breach of
the same or another provision hereof.

        Section 8.8 ENFORCEMENT. In the event either party resorts to legal
action to enforce or interpret any provision of this Management Services
Agreement, the prevailing party shall be entitled to recover the costs and
expenses of such action so incurred, including, without limitation, reasonable
attorneys' fees.

        Section 8.9 GENDER AND NUMBER. Whenever the context of this Management
Services Agreement requires, the gender of all words herein shall include the
masculine, feminine, and neuter, and the number of all words herein shall
include the singular and plural.

        Section 8.10 ADDITIONAL ASSURANCES. Except as may be herein specifically
provided to the contrary, the provisions of this Management Services Agreement
shall be self-operative and shall not require further agreement by the parties;
provided, however, at the request of either par ty, the other party shall
execute such additional instruments and take such additional acts as are
reasonable and as the requesting party may deem necessary to effectuate this
Management Services Agreement.

        Section 8.11 CONSENTS, APPROVALS, AND EXERCISE OF DISCRETION. Whenever
this Management Services Agreement requires any consent or approval to be given

where specifically set forth to the contrary, the parties agree that such
consent or approval shall not be unreasonably withheld or delayed, and that such
discretion shall be reasonably exercised.

        Section 8.12 FORCE MAJEURE. Neither party shall be liable or deemed to
be in default for any delay or failure in performance under this Management
Services Agreement or other interruption of service deemed to result, directly
or indirectly, from acts of God, civil or military authority, acts of public
enemy, war, accidents, fires, explosions, earthquakes, floods, failure of
transportation, strikes or other work interruptions by either party's employees,
or any other sim ilar cause beyond the reasonable control of either party unless
such delay or failure in performance is expressly addressed elsewhere in this
Management Services Agreement.

prepared the terms of this Management Services Agreement in good faith with the
intent that each and every one of the terms, covenants and conditions herein be
binding upon and inure to the benefit of the respective parties. Accordingly, if

circumstance shall be adjudged to any extent invalid, unenforceable, void or
voidable for any reason whatsoever by a court of competent jurisdiction or an
arbitration tribunal, such provision shall be as narrowly construed as possible,
and each and all of the remaining terms, provisions, promises, covenants and
conditions of this Management Services Agreement or their application to other
persons or circumstances shall not be affected thereby and shall be valid and
enforceable to the fullest extent permitted by law. To the extent this
Management Services Agreement is in violation of applicable law, then the

                                    EXHIBIT E

                               ANCILLARY AGREEMENT

        AGREEMENT dated as of ___________, 1996 by and among Castle Dental
Centers of New York, Inc., a New York corporation ("Purchaser"), Castle Dental
Centers, Inc., a Delaware corporation ("Castle"), Jules V. Lane D.D.S. d/b/a
American Dental Centers, J.V. Lane Professional Corporation, a New York
professional corporation d/b/a American Dental Centers ("Lane PC"), Lisadent
Corp. ("Lisadent") (collectively "Seller") and Jules V. Lane D.D.S.("Dr. Lane"),
the sole shareholder of Lane PC and one of the shareholders of Lisadent, and
Linda Lane, the other shareholder of Lisadent (Dr. Lane and Linda Lane are
referred to collectively as the "Shareholders").

        1. INTRODUCTION. Prior to the date of this Agreement, on August __,
1996, the parties hereto entered into an Asset Purchase Agreement (the "Asset
Purchase Agreement") providing for the purchase by Purchaser of certain
identified assets of Seller as more fully described therein. Contemporaneously
with the execution and delivery of this Agreement, the parties hereto have
entered into certain additional agreements contemplated by the Asset Purchase
Agreement. The parties hereto have entered into this Agreement to document
certain additional agreements reached by them in connection with the Asset
Purchase Agreement and the other documents executed and delivered
contemporaneously herewith, and the transactions contemplated thereby. Initially
capitalized terms not otherwise defined herein shall have the meanings assigned
to such terms in the Asset Purchase Agreement.

        2. PURCHASE OF MALPRACTICE AND "TAIL" INSURANCE; ACCESS TO RECORDS. From
and after the date hereof, until Purchaser and Castle purchase or cause to be
purchased the "tail" insurance hereinafter described, Purchaser and Castle agree
to pay up to $12,000 per year for professional liability insurance for Dr. Lane
in an amount of $2,000,000 per claim, $6,000,000 aggregate of all claims, with a
reputable insurance company selected by Dr. Lane. It is expressly understood
that
<PAGE>
the maximum annual obligation of Purchaser and Castle for such insurance is
$12,000, irrespective of actual cost. Purchaser and Castle agree that on the
earliest to occur of (i) such time as Dr. Lane is no longer a shareholder of
Lane PC, (ii) the Management Services Agreement by and between Purchaser and
Lane PC ("Management Services Agreement") is terminated for any reason, or (iii)
Dr. Lane is no longer an employee of Purchaser, notwithstanding the provisions
of the Management Services Agreement to the contrary, Castle will, irrespective
of the cost thereof, purchase or cause to be purchased malpractice "tail"
insurance in such amount and covering such risks as the malpractice insurance
carried by, or on behalf of Dr. Lane on the date he ceased to be a shareholder
of Lane PC or the date the Management Services Agreement terminates, whichever
occurs first.. The tail insurance shall have a coverage term of not less than 15
years.

        From and after such time on the earliest to occur of (i) Dr. Lane is no
longer a shareholder of Lane PC, (ii) the Management Services Agreement is
terminated for any reason, or (iii) Dr. Lane is no longer an employee of
Purchaser, Castle will ensure that Dr. Lane shall have access to patient records
of patients of Lane PC for all lawful purposes for a period of not less than
seven years from the date Dr. Lane ceased to be a shareholder of Lane PC or the
Management Services Agreement terminated, and with respect to records pertaining
to a claim raised during such seven year period, for such longer period as is
required to resolve such claim fully, including all appeals thereof.

        3. USE OF THE NAME "JULES V. LANE". From and after the Closing date,
Seller and Dr. Lane hereby grant to the Purchaser and Castle the perpetual and
exclusive right to use and license the name "Jules V. Lane" and all derivatives
thereof, to professional corporations or other entities providing dental
services to which the Purchaser or Castle or one of their respective affiliates
provide management services. In connection therewith, Castle and Purchaser agree
to use the name in a dignified, respectful and professional manner, and in a
manner reasonably calculated not to precipitate enforcement action by the New
York State Dental Board against Dr. Lane's license.

        4. INDEMNIFICATION OF DR. LANE. From and after the Closing Date for so
long as Dr. Lane serves as a director of Castle, Castle agrees to maintain in
full force and effect an Indemnity Agreement with Dr. Lane, in substantially the
form to which other directors of Castle are parties. Additionally, for such
period as Dr. Lane serves as a director of Castle, Castle agrees to provide Dr.
Lane with the same directors' and officers' insurance coverage made available to
other directors of Castle. Castle hereby agrees to indemnify and hold Dr. Lane
harmless from and against any and all damages, penalties, losses, deficiencies,
costs, expenses, obligations, fines, expenditures, claims and liabilities,
including reasonable counsel fees and reasonable expenses of investigation,
defending and prosecuting litigation (collectively, the "Damages"), suffered by
Dr. Lane (i) as a result of, caused by or arising out of the failure of the
Purchaser to perform its obligations to Lane PC under the Management Services
Agreement after the Closing Date, including but not limited to (a) the payment
by the Purchaser on behalf of Lane PC to the Internal Revenue Service and other

                                       -2-
<PAGE>
appropriate agencies of all required payroll and withholding taxes on employees
of Lane PC, and (b) the failure of Purchaser to perform any obligations assumed
by Purchaser under the Management Services Agreement in respect of pension
plans, if any, adopted by Lane PC in the future; (ii) arising out of the use of
Dr. Lane's name and/or professional license (but not the loss of his
professional license) after the Closing Date, as contemplated by Section 3
hereof; (iii) in his capacity as an officer, director or shareholder of Lane PC
for liabilities of Lane PC arising after the Closing Date; and (iv) as the
result of the failure by Castle to perform any obligations of Castle to Dr. Lane
from and after the Closing Date contained herein or in any other agreement to
which Dr. Lane and Castle are parties; provided, however, that Dr. Lane shall
not be entitled to indemnification from Castle with respect to any matter in
which professional negligence is alleged, it being the intent of the parties
hereto that such matters be insured against by Dr. Lane and paid for as provided
elsewhere herein; and provided further, that to qualify for indemnification
hereunder, the Board of Directors of Castle shall have determined in good faith
that in connection with such matters for which indemnification is sought by Dr.
Lane hereunder, he shall have acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of Lane PC and the
Purchaser. Pending the outcome of any such action, the Company shall advance Dr.
Lane the costs of defense if (a) Dr. Lane provides an opinion of counsel
reasonably acceptable to the Company that in the opinion of such counsel, Dr.
Lane ultimately will be entitled to indemnification hereunder, and (b) Dr. Lane
provides the Company with a written undertaking to reimburse such advances if it
is not ultimately determined by a court of competent jurisdiction that Dr. Lane
is entitled to indemnification hereunder. To the extent that Dr. Lane has been
successful on the merits or otherwise in defense of any action, suit or
proceeding referred to herein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

        5. RESPONSIBILITY FOR LIABILITIES OF LANE PC. Dr. Lane hereby agrees
that all liabilities of Lane PC, not covered by malpractice insurance whether
known or unknown, liquidated or unliquidated or fixed or contingent which exist
as of the Closing Date, or which arise after the Closing Date but are based on
facts or circumstances affecting Lane PC prior to or as of the Closing Date,
other than those liabilities of Lane PC which arise solely as a result of the
consummation of the transactions contemplated by the Asset Purchase Agreement or
the Management Services Agreement or are expressly assumed by Purchaser in
Section 2.3 of the Asset Purchase Agreement, shall be for the account of Dr.
Lane; it being the intent of the parties that as of the Closing Date, Lane PC
shall have no liabilities of any kind whatsoever attributable to periods prior
to the Closing Date other than those contemplated by the Asset Purchase
Agreement, including Section 2.3 thereof, or the Management Services Agreement.
Dr. Lane hereby agrees to indemnify and hold Lane PC, Castle and the Purchaser
harmless from and against any and all damages, penalties, losses, deficien cies,
costs, expenses, obligations, fines, expenditures, claims and liabilities,
including reasonable counsel fees and reasonable expenses of investigation,

result of, caused by or arising out of, the failure of Dr. Lane to discharge and
satisfy all of the liabilities of Lane PC attributable to periods prior to the
Closing Date, other than those contemplated by the Asset Purchase Agreement
including Section 2.3 thereof, or the Management Services Agreement, including
but not limited to, the payment by Lane PC to the Internal Revenue Service and

directly or through agents, Dr. Lane agrees to notify Purchaser and Castle in
writing of this intent to solicit offers to purchase American Medical and to
provide the Purchaser and Castle a period of not less than 30 days to make an
offer to purchase American Medical. During such 30 day period, Purchaser, Castle

diligence review of the business and affairs of American Medical necessary to
permit them to make an informed evaluation of the business and affairs of
American Medical. Purchaser and Castle agree to execute confidentiality
agreements in usual and customary form prior to commencing such due diligence
review.

        In the event Purchaser and Castle elect, during such 30 day period to
deliver to Dr. Lane a written offer to purchase American Medical, Dr. Lane
agrees to negotiate in good faith exclusively with Purchaser and Castle for an
additional period of 30 days after receiving such written offer from Purchaser
and Castle with a view to reaching a definitive agreement for the purchase and
sale of American Medical; provided, however, that the parties are under no
obligation to reach an agreement.

        7. ADDITIONAL MATTERS PERTAINING TO AMERICAN MEDICAL. Notwithstanding
anything contained in this Agreement to the contrary, with the exception of the
foregoing Section, nothing contained in this Agreement, the Asset Purchase
Agreement, the Management Services Agreement the Employment Agreement, or any

Purchaser, Castle or Lane PC any rights with respect to American Medical, its
assets, its business or the way in which it conducts its business, all such
matters being expressly excluded from the scope of the foregoing instruments.

               (c) Employee's material violation of this Agreement or commission
of an act of gross negligence or willful misconduct (in the case of a breach,
following notice thereof to Employee by the Company and a thirty day period
thereafter within which Employee shall have the opportunity to cure such breach)
that has or is reasonably expected to have a material adverse effect on the
business or affairs of the Company;

               (d) the conviction for a Class A felony, after exhaustion of all

termination of the Management Services Agreement by and between the Company and

the Management Services Agreement.

        A notice of termination pursuant to this Section 3.4 shall be in writing
and shall state the reason for termination. Within not less than five (5) nor
more than twenty (20) days after such notice, Employee shall be given the
opportunity to appear before the Board of Directors of the Company, or a
committee thereof, to rebut or dispute the alleged violation. If the Board of
Directors or committee makes a good faith reasonable determination, by vote of a
majority of the directors other than Employee (if Employee is then a director),
that one or more grounds exist for termination of Employee for Cause, the
Company may immediately terminate Employee's employment under this Section 3.4.
The Company may elect, during the pendency of any inquiry relative to
termination of Employee, to relieve Employee of his regular duties with pay.

        3.5 TERMINATION BY EMPLOYEE FOR CAUSE. The Employee may terminate this
Agreement for "Cause" for any of the following grounds:

               (a) the continued failure of the Company to pay Employee the
amounts contemplated by Article II hereof for 10 days following notice thereof
from Employee; provided, however, that Employee shall not be required to give
more than two notices in any twelve month period; or

               (b) material violation of this Agreement following notice thereof
to the Company by Employee and a thirty day period thereafter within which the
Company shall have the opportunity to cure such breach, which breach has or is
reasonably expected to have a material adverse effect on the Employee.

        A notice of termination pursuant to this Section 3.5 shall be in writing
and shall state the reason for termination.

        3.6 SEVERANCE PAY. In the event of termination, Employee shall be
entitled to compensation (the "Severance Pay") in accordance with the following:

               (a) If Employee's employment is terminated by reason of his
disability, the Company shall continue to pay Employee's monthly Base Salary,
(at his then current Base Salary rate excluding any increases that would have
taken effect beyond the date of termination and any noncash benefits) the
Employee would have earned for the three month period subsequent to the

                                       -4-
<PAGE>
effective date of termination, payable at such time or times as would have been
paid to Employee had he remained employed by the Company.

               (b) If (i) Employee voluntarily terminates his employment, or
(ii) the Company terminates this Agreement for Cause, or (iii) if Employee's
employment is terminated by reason of his death, Employee shall not be entitled
to receive any additional salary or benefits beyond those earned or accrued as
of the effective date of the termination of his employment.

               (c) If Employee's employment hereunder is terminated prior to the
expiration of the term of this Agreement, and such termination is either (i) by
the Employee for Cause, or (ii) by the Company and not for Cause, Employee shall
be entitled to Severance Pay in an amount equal to the amount of Base Salary
that the Employee would have earned for the remainder of the three year period
commencing on the date hereof, less applicable payroll deductions (and any other
deductions authorized in writing by the Employee), payable at such time or times
as would have been paid to Employee had he remained employed by the Company
through such term.

        3.7 EFFECT OF TERMINATION ON AGREEMENT. Any termination of Employee's
employment shall not release either the Company or Employee from their
respective obligations under this Agreement that are required to be performed
subsequent to the date of such termination, including but not limited to those
obligations set forth under Section 3.6, 3.8 and Articles IV and V. No
termination of this Agreement shall diminish in any way the rights, duties and
obligations of any party under the Ancillary Agreement of even date herewith. On
the termination or expiration of this Agreement for any reason, the Company
agrees to exercise its rights under the Option Agreement between Company and
Employee.

        3.8 PAYMENTS TO ESTATE. If Employee should die before all amounts
payable to him pursuant to Section 3.6 have been paid, such unpaid amounts shall
be paid to the personal representative of Employee's estate.

        4.1 NONDISCLOSURE AND NONUSE OF CONFIDENTIAL INFORMATION. Employee
understands and agrees that his employment by the Company creates a relationship
of confidence and trust between himself and the Company with respect to
Confidential Information (as defined below). Employee recognizes that he will
have access to and knowledge of Confidential Information. Employee will not,
during or after the term of his employment by the Company, in whole or in part,
disclose such Confidential Information to any person, firm, corporation,
association, or other entity for any reason or purpose whatsoever, nor shall he
make use of any such Confidential Information

                                       -5-

nothing in this Article shall be construed to prohibit the disclosure of such
Confidential Information by the Employee (i) to another officer, director
employee or agent of the Company; (ii) as is reasonably necessary for the
performance of his duties and responsibilities under this Agreement; or (iii) as
otherwise required by law. If Employee is required by law to disclose
"Confidential Information," Employee shall notify the Company's Board of
Directors, in writing, of the nature of such disclosure and the Confidential
Information to be disclosed, as soon as is possible and/or practical, and permit
the Company the opportunity to contest or limit such disclosure.

        4.2 CONFIDENTIAL INFORMATION DEFINED. The term "Confidential
Information" shall mean any information of the Company (whether written or
oral), including all notes, studies, patient lists, information, forms, business
or management methods, marketing data, fee schedules, or trade secrets of the
Company. Confidential Information shall also include the terms and provisions of
this Employment Agreement and any transaction or document executed by the
parties pursuant to this Employment Agreement. Confidential Information does not

indirectly by Employee or his affiliates, advisors, or representatives); (ii) is
or becomes available to the receiving party on a nonconfidential basis from a
source other than the Employee or its affiliates, advisors, or representatives,
provided that such source is not and was not bound by a confidentiality
agreement with or other obligation of secrecy to the Company of which the
receiving party has knowledge at the time of such disclosure; or (iii) has
already been or is hereafter independently acquired or developed by the
receiving party without violating any confidentiality agreement with or other
obligation of secrecy to the Company. Information in the possession of Employee
pertaining to AMLI and its business and the way in which it conducts its
business, including but not limited to its dental managed care and indemnity
business, which includes, without limitation, a dual choice option, shall not be
included within the term "Confidential Information."

documents, which are made, composed, or received by Employee, solely or jointly
with others, during the term of his employment and which are in Employee's

to the past, present or anticipated business of the Company, excluding therefrom

employment and during the twenty-four months following the termination of the
Employee's employment, Employee agrees not to solicit or induce any employee of
the Company or Lane PC to terminate his or her employment, accept employment
with anyone else, or to interfere in a similar manner with the business of the
Company or Lane PC.

        5.2 NONSOLICITATION OF CUSTOMERS AND SUPPLIERS During the employment of
the Employee pursuant to this Agreement and during the twenty-four months
following the termination of the Employee's employment, Employee agrees not to
contact, communicate with or solicit any customer, supplier, vendor,
distributor, promoter, contractor or prospective customer of the Company or Lane
PC for the purpose of engaging in the Same or Similar Business (as defined
below) as the Company.

        5.3 NONCOMPETITION. Employee recognizes that in connection with the
performance of the Employee's duties and obligations under this Agreement, the
Company will provide Employee with confidential, proprietary and trade secret
information, which is necessary to Employee's employment with the Company, and
which Employee has agreed to protect and maintain as confidential, proprietary
and trade secret information for the Company's benefit. To protect and maintain
the confidentiality of the information, Employee agrees that, during the
employment of the Employee pursuant to this Agreement, including the period
during which Employee is receiving Severance Pay hereunder, and during the
twenty-four months following such period, Employee shall not directly or
indirectly engage in, manage, operate, join, control, or participate in the
ownership, management, operation, or control of, or be employed or engaged or
act as a consultant to in any manner by, any business competing in the Same or
Similar Business as the Company or Lane PC within a ten mile radius around any
dental center managed by this Company in the State of New York. The provisions

affiliates or leases to the Company of real property used for dental offices.

        5.4 SAME OR SIMILAR BUSINESS DEFINED. For purposes of this Article V,

such services or practices, or the management of or consulting with dental

including but not limited to its dental managed care and indemnity business,
which includes, without limitation, a dual choice option.

        5.5 REASONABLENESS OF RESTRICTIONS. Employee has carefully read and
considered the provisions of this Article V and, having done so, agrees that the
restrictions set forth in such Article contain reasonable limitations as to
time, geographical area, scope of activity to be restrained, and do not impose a
greater restraint than is necessary to protect the goodwill or other legitimate
business interests of the Company. The Employee further understands and agrees
that, if at some later date, a court of competent jurisdiction determines that
the scope, duration or geographic area of any covenant set forth in this Article
is overbroad or unenforceable for any reason, these covenants shall be reformed
by the court and enforced to the maximum extent permissible under New York law.

shall be assignable, except that his personal representatives and heirs may
enforce the obligations of the Company hereunder.

        6.2 WAIVER OF BREACH. The waiver by any party to this Agreement of a
breach or violation of any provisions hereof shall not operate or be construed

or shall be deemed given five (5) business days after sent by certified mail,

governed in accordance with the laws of the State of New York without regard to
conflict of laws provision. This Agreement is performable in Nassau County, New

counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same agreement. A fully executed copy of
this Agreement shall be delivered to each party hereto.

        6.7 LEGAL CONSTRUCTION. In case anyone or more of the provisions
contained in this Agreement shall for any reason be held to be invalid, illegal,
or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not effect any other provision hereof, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein. In addition, such invalid, illegal or unenforceable
provision shall be modified to the minimum extent necessary to permit it to be
valid, legal and enforceable. Except as otherwise provided for herein to the
contrary, for all purposes hereof "day" shall mean calendar day and shall
include weekends and holidays; provided, however, that if any notice period
terminates on a weekend or holiday, the person who is required to deliver the
notice shall have until the next business day to complete the notice
requirement.

        6.8 AMENDMENT. No modification, amendment, addition to, or termination
of this Agreement, nor waiver of any of its provisions, shall be valid or
enforceable unless it is in writing and signed by all of the parties hereto.

        6.9 PRIOR AGREEMENTS SUPERSEDED. This Agreement constitutes the sole and
only Agreement of the parties hereto with respect to the subject matter hereof,

matter hereof.

CONNECTION WITH ANY PROCEEDING UNDER THIS SECTION SHALL BE PAID BY THE
NON-PREVAILING

THIS SECTION SHALL BE CONSTRUED TO REQUIRE THE ARBITRATION OF ANY DISPUTE OR
CLAIM (i) ARISING UNDER ARTICLES IV OR V OF THIS AGREEMENT; (ii) FOR

BY THEIR EXECUTION OF THIS AGREEMENT, EACH PARTY TO THIS AGREEMENT CONSENTS, ON

                               MARKETING AGREEMENT

        THIS MARKETING AGREEMENT (the "Agreement") dated as of ___________, 1996
by and among Castle Dental Centers of New York, Inc., a New York corporation
("Castle"), Castle Dental Centers, Inc., a Delaware Corporation ("CDC"),
American Medical and Life Insurance Company, a New York insurance company
("AMLI"), and Jules V. Lane D.D.S.("Dr. Lane") who agree as follows:

1. INTRODUCTION. Prior to the date of this Agreement, on September 3, 1996,
Castle, Dr. Lane and certain other parties entered into an Asset Purchase
Agreement (the "Asset Purchase Agreement") which contemplated the purchase by
Castle of certain identified assets and the negotiation and execution of certain
other agreements between Castle and certain other parties, all as more fully
described in the Asset Purchase Agreement. The parties hereto have entered into
this Agreement to document certain of such additional agreements reached by them
as contemplated by the Asset Purchase Agreement. Initially capitalized terms not
otherwise defined herein shall have the meanings assigned to such terms in the
Asset Purchase Agreement.

2. RECIPROCAL MARKETING ARRANGEMENT. In markets in the State of New York served
by dental practices managed by Castle in which AMLI offers dental insurance,
AMLI agrees (i) to include information provided by Castle regarding its managed
dental practices in marketing materials produced and distributed by or on behalf
of AMLI relating to dental insurance or the provision of dental services to AMLI
policyholders, and (ii) subject to the ability of AMLI to reach agreement with
such managed dental practices regarding fee structure and the ability of Castle
to perform contracted services, to maintain preferred provider relationships
with dental practices managed by Castle and to offer such dental practices as
preferred providers to AMLI policyholders and other covered parties. AMLI shall
have the right to approve the information provided by Castle for inclusion in
the AMLI marketing materials, such approval not to be unreasonably withheld.

In markets in the State of New York served by dental practices managed by Castle
in which AMLI offers dental insurance, Castle agrees to include information
provided by AMLI regarding its insurance programs in marketing materials

provided by AMLI for inclusion in the marketing materials produced and
distributed by or on behalf of dental practices managed by Castle, such approval
not to be unreasonably withheld.

3. RECIPROCAL RIGHT OF FIRST REFUSAL FOR ADDITIONAL MARKETS. AMLI agrees to
offer dental practices managed by Castle or one of its affiliates the right of
first refusal to participate on substantially the same terms and conditions as
set forth in Section 2 in markets in states other than New York in which AMLI
offers dental insurance. CDC agrees to cause its appropriate affiliate to offer
AMLI the right of first refusal to participate on substantially the same terms
and conditions as set forth in Section 2 in markets in states other than New
York in which an affiliate of CDC manages dental practices and in which AMLI is
licensed to offer dental insurance.

4. OBLIGATIONS SUBJECT TO REGULATORY COMPLIANCE. The obligations of CDC or its
affiliates and AMLI herein are subject to the ability of CDC or its affiliates
and/or AMLI to perform their respective obligations hereunder in compliance with
applicable laws and regulations of the jurisdictions in which the performance of
this Agreement will be undertaken. Nothing contained herein shall be construed
as requiring any party hereto to act in violation of such laws and regulations.

5. CONFIDENTIALITY. The parties hereto acknowledge that the transactions
contemplated by this Agreement involve the likelihood of each party hereto
having access to and knowledge of Confidential Information (as hereinafter
defined) of the other. CDC, on behalf of itself and its affiliates, and AMLI
each agree that it will not, during or after the term of this Agreement, in
whole or in part, disclose such Confidential Information of the other to any
person, firm, corporation, association, or other entity for any reason or
purpose whatsoever, nor shall it make use of any such Confidential Information
for its own purposes or for the purposes of others; provided, however, that
nothing in this Section shall be construed to prohibit the disclosure of such
Confidential Information by a party hereto (i) to an officer, director employee
or agent of CDC or its affiliates or AMLI who is subject to a confidentiality
obligation in favor of the disclosing party; (ii) as is reasonably necessary for
the performance of its duties and responsibilities under this Agreement; or
(iii) as otherwise required by law. If a party hereto is required by law to
disclose "Confidential Information," such party shall notify the other party, in
writing, of the nature of such disclosure and the Confidential Information to be
disclosed, as soon as is possible and/or practical, and permit such other party
the opportunity to contest or limit such disclosure.

6. CONFIDENTIAL INFORMATION DEFINED. The term "Confidential Information" shall
mean any information of CDC or its affiliates or AMLI, as the case may be
(whether written or oral), including all notes, studies, patient lists,
information, forms, business or management methods,

                                       -2-
<PAGE>
marketing data, fee schedules, or trade secrets of CDC or its affiliates or
AMLI, as the case may be. Confidential Information shall also include the terms
and provisions of this Agreement and any transaction or document executed by the
parties pursuant to this Agreement. Confidential Information does not include
any information that (i) is or becomes generally available to and known by the
public (other than as a result of an unpermitted disclosure directly or
indirectly by a party hereto or its affiliates, advisors, or representatives);
(ii) is or becomes available to the receiving party on a nonconfidential basis
from a source other than a party hereto or its affiliates, advisors, or
representatives, provided that such source is not and was not bound by a
confidentiality agreement with or other obligation of secrecy to a party hereto
of which the receiving party has knowledge at the time of such disclosure; or
(iii) has already been or is hereafter independently acquired or developed by
the receiving party without violating any confidentiality agreement with or
other obligation of secrecy to a party hereto.

7. DELIVERY OF MATERIALS. Each party hereto further agrees to deliver to the
other at the termination of this Agreement, or at any other time upon request,
all correspondence, memoranda, notes, records (including computer records and
data), drawings, sketches, plans, customer lists, and other documents, which are
made, composed, or received by a party hereto solely or jointly with others,

of all facilities and equipment to be shared by Castle and AMLI and the
ownership thereof. Castle and AMLI agree as to the accuracy of the information
contained on Schedule I.

3. USE OF SHARED FACILITIES AND EQUIPMENT. Castle and AMLI agree that for the

or representatives); (ii) is or becomes available to the receiving party on a

developed by the receiving party without violating any confidentiality agreement

Option may be exercised by Optionee in the event of a change in applicable law
permitting the Optionee to acquire the Shareholder Interest or by a qualified
designee of the Optionee in the event that the Optionee determines to transfer
the Shareholder Interest to a designee of the Optionee qualified under
applicable law to own the Shareholder Interest. The Optionee agrees that the
Option shall be exercised in a manner to ensure that the ownership of the
Shareholder Interest will not violate any applicable laws.

        2. EXERCISE PRICE. The exercise price (the "Exercise Price") for the
Shareholder Interest shall be One Hundred Dollars ($100.00).

<PAGE>
        4. EXERCISE OF OPTION. On the execution of this Option Agreement, the
Option shall immediately become exercisable and shall be exercisable at any time
thereafter until the Expiration Date (the "Option Period"); provided that in no
event shall the Option be exercisable by Optionee or by any transferee under
Section 7 until such time as Optionee or such transferee shall have taken such
action as may be necessary to permit such person to lawfully hold an ownership
interest in Lane PC.

        5. NOTICE PERIOD. Before exercising the Option, Optionee shall give at
least twenty-four (24) hours written notice to Shareholder (or Shareholder's
representative). During the notice period, Shareholder (or Shareholder's
representative) may not sell, transfer, exchange, encumber, or otherwise
alienate the Shareholder Interest. Any such sale, transfer, exchange,
encumbrance, or alienation shall be void. In addition, during the notice period,

Exercise Price and evidence of the purchase of "tail insurance" on behalf of
Shareholder as contemplated by the Ancillary Agreement of even date herewith, to

good standing and in compliance with all laws and regulations of the State of
New York relating to the practice of dentistry, and to maintain professional

Optionee will take no action calculated to cause Shareholder to be unable to
maintain his license to practice dentistry in good standing and in compliance
with all such laws and regulations; provided, however, in no event shall any

                           CASTLE DENTAL CENTERS, INC.
                        INCENTIVE STOCK OPTION AGREEMENT

        This Incentive Stock Option Agreement ("Option Agreement") is between
Castle Dental Centers, Inc., a Delaware corporation (the "Company"), and G.
Powell Bilyeu ("Optionee"), who agree as follows:

        Section 1. INTRODUCTION. The Company has heretofore adopted the Castle
Dental Centers, Inc. Omnibus Stock and Incentive Plan (the "Plan") for the
purpose of providing eligible key employees and directors of the Company and its
Affiliates (as defined in the Plan) with increased incentive to render services,
to exert maximum effort for the business success of the Company and to
strengthen the identification of employees and directors with the shareholders.
The Company, acting through its Board of Directors (the "Board"), has determined
that its interests will be advanced by the issuance to Optionee of an incentive
stock option under the Plan.

        Section 2. OPTION. Subject to the terms and conditions contained herein,
the Company hereby irrevocably grants to Optionee the right and option
("Option") to purchase from the Company 50,000 shares of the Company's common
stock, $.001 par value ("Common Stock"), at a price of $5.00 per share, which is
deemed to be not less than the fair market value of the Common Stock at the date
of grant of this Option.

        Section 3. OPTION PERIOD. The Option herein granted may be exercised by
Optionee in whole or in part at any time during a five year period beginning on
May 31, 1997 (the "Option Period"), subject to the limitation that said Option
shall not be exercisable for more than a percentage of the aggregate number of
shares offered by this Option determined by the number of full years of
employment with the Company or its Affiliates from the effective date of
Optionee's grant, to the date of such exercise, in accordance with the following
schedule:

         Number of                                     Percentage of
         FULL YEARS                                SHARES PURCHASABLE

             1                                              20%
             2                                              40%
             3                                              60%
             4                                              80%
             5                                             100%

                                       -1-
<PAGE>
Notwithstanding anything in this Option Agreement to the contrary, the Board, in
its sole discretion, may waive the foregoing schedule of vesting and upon
written notice to Optionee, accelerate the earliest date or dates on which any
of the Options granted hereunder are exercisable.

        Section 4. PROCEDURE FOR EXERCISE. The Option herein granted may be
exercised by the delivery by Optionee of written notice to the Secretary of the
Company setting forth the number of shares of Common Stock with respect to which
the Option is being exercised. The notice shall be accompanied by, at the
election of the Optionee, (i) cash, cashier's check, bank draft, or postal or
express money order payable to the order of the Company, (ii) certificates
representing shares of Common Stock theretofore owned by Optionee duly endorsed
for transfer to the Company, (iii) an election by Optionee to have the Company
withhold shares of Common Stock issuable upon exercise of the Option, or (iv)
any combination of the preceding, equal in value to the aggregate exercise
price. Notice may also be delivered by telecopy provided that the exercise price
of such shares is received by the Company via wire transfer on the same day the
telecopy transmission is received by the Company. The notice shall specify the
name in which such Shares are issued and the address to which the certificates
for such shares are to be mailed. An option to purchase shares of Common Stock
in accordance with this Plan, shall be deemed to have been exercised immediately
prior to the close of business on the date (i) written notice of such exercise
and (ii) payment in full of the exercise price for the number of shares for
which Options are being exercised, are both received by the Company and Optionee
shall be treated for all purposes as the record holder of such shares of Common
Stock as of such date.

        As promptly as practicable after receipt of such written notice and
payment, the Company shall deliver to Optionee certificates for the number of
shares with respect to which such Option has been so exercised, issued in
Optionee's name or such other name as Optionee directs; provided, however, that
such delivery shall be deemed effected for all purposes when a stock transfer
agent of the Company shall have deposited such certificates in the United States
mail, addressed to Optionee at the address specified pursuant to this Section 4.

        Section 5. TERMINATION OF EMPLOYMENT. If Optionee ceases to be employed
by the Company or its Affiliates for any reason other than death or disability,
any Option which is exercisable on the date of such termination of employment
shall expire upon such date of such termination of employment; provided,
however, the Board, in its sole discretion, may allow Optionee to exercise all
or a portion of the options granted but unexercised for a period of time after
Optionee's termination of employment.

        Section 6. DISABILITY OR DEATH. In the event that Optionee dies or is
determined to be disabled while Optionee is employed by the Company, the options
previously granted to Optionee may be exercised (to the extent Optionee would
have been entitled to do so at the date of death or the determination of
disability) at any time and from time to time, within a one-year period after
such death or determination of disability, by the Optionee, the guardian of
Optionee's estate, the executor or administrator of Optionee's estate or by the
person or persons to whom Optionee's rights under

                                       -2-
<PAGE>
this Option Agreement shall pass by will or the laws of descent and
distribution, but in no event may the Option be exercised after its expiration
under the terms of this Option Agreement. An Optionee shall be deemed to be
disabled if, in the opinion of a physician selected by the Board, Optionee is
incapable of performing services for the Company of the kind Optionee was
performing at the time the disability occurred by reason of any medically
determinable physical or mental impairment which can be expected to result in
death or to be of long, continued and indefinite duration. The date of
determination of disability for purposes hereof shall be the date of such
determination by such physician.

        Section 7. TRANSFERABILITY. This Option shall not be transferable by
Optionee otherwise than by Optionee's will or by the laws of descent and
distribution or pursuant to a transfer which is incident to a divorce, as
described in Code Section 1041(a). During the lifetime of Optionee, the Option
shall be exercisable only by Optionee or his authorized legal representative.
Any heir or legatee of Optionee shall take rights herein granted subject to the
terms and conditions hereof. No such transfer of this Option Agreement to heirs
or legatees of Optionee shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and a copy of such
evidence as the Board may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions hereof.

        Section 8. NO RIGHTS AS SHAREHOLDER. Optionee shall have no rights as a
shareholder with respect to any shares of Common Stock covered by this Option
Agreement until the Option is exercised by written notice and accompanied by
payment as provided in Section 4 of this Option Agreement.

        Section 9. EXTRAORDINARY CORPORATE TRANSACTIONS. The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its shareholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issuance of Common Stock or subscription rights thereto, or any issuance of
bonds, debentures, preferred or prior preference stock ahead of or affecting the
Common Stock or the rights thereof, or the dissolution or liquidation of the
Company, or any sale or transfer of all or any part of its assets or business,
or any other corporate act or proceedings, whether of a similar character or
otherwise. If the Company goes through a "Fundamental Change" or a "Corporate
Change" (as defined in subsection 8.4 of the Plan), the Options granted
hereunder shall be governed by subsection 8.4 of the Plan.

        Section 10. CHANGES IN CAPITAL STRUCTURE. If the outstanding shares of
Common Stock or other securities of the Company, or both, for which the Option
is then exercisable shall at any time be changed or exchanged by declaration of
a stock dividend, stock split, combination of shares, or recapitalization, the
number and kind of shares of Common Stock or other securities subject to the
Plan or subject to the Option and the exercise price, shall be appropriately and
equitably adjusted

                                       -3-
<PAGE>
so as to maintain the proportionate number of shares or other securities without
changing the aggre gate exercise price.

        Section 11. SHAREHOLDER AGREEMENT. Optionee, or Optionee's
representative upon Optionee's death, prior to the exercise of an Option granted
hereunder, agrees to enter into the Company's Shareholders Agreement at the
request of the Company.

        Section 12. COMPLIANCE WITH SECURITIES LAWS. Upon the acquisition of any
shares pursuant to the exercise of the Option herein granted, Optionee (or any
person acting under Section 7) will enter into such written representations,
warranties and agreements as the Company may reasonably request in order to
comply with applicable securities laws or with this Option Agreement.

        Section 13. COMPLIANCE WITH LAWS. Notwithstanding any of the other
provisions hereof, Optionee agrees that he or she will not exercise the Option
granted hereby, and that the Company will not be obligated to issue any shares
pursuant to this Option Agreement, if the exercise of the Option or the issuance
of such shares of Common Stock would constitute a violation by Optionee or by
the Company of any provision of any law or regulation of any governmental
authority.

        Section 14. NO RIGHT TO EMPLOYMENT. Optionee who is an employee shall be
considered to be in the employment of the Company so long as he or she remains
an employee of the Company or its Affiliates. Any questions as to whether and
when there has been a termination of such employment and the cause of such
termination shall be determined by the Board, and its determination shall be
final. Nothing contained herein shall be construed as conferring upon Optionee
the right to continue in the employ of the Company, nor shall anything contained
herein be construed or interpreted to limit the "employment at will"
relationship between Optionee and the Company.

        Section 15. RESOLUTION OF DISPUTES. As a condition of the granting of
the Option hereby, Optionee, and Optionee's heirs, personal representatives and
successors agree that any dispute or disagreement which may arise hereunder
shall be determined by the Board, in its sole discretion and judgment, and that
any such determination and any interpretation by the Board of the terms of this
Option Agreement shall be final and shall be binding and conclusive, for all
purposes, upon the Company, Optionee, and Optionee's heirs, personal
representatives and successors.

        Section 16. LEGENDS ON CERTIFICATE. The certificates representing the
shares of Common Stock purchased by exercise of the Option will be stamped or
otherwise imprinted with legends in such form as the Company or its counsel may
require with respect to any applicable restrictions on sale or transfer and the
stock transfer records of the Company will reflect stop-transfer instructions
with respect to such shares.

        Section 17. NOTICES. Every notice hereunder shall be in writing and
shall be given by registered or certified mail. All notices of the exercise of
any Option hereunder shall be directed to

existence, maturity or termination of any of Optionee's rights hereunder and
Optionee shall be deemed to have familiarized himself or herself with all
matters contained herein and in the Plan which may affect any of Optionee's
rights or privileges hereunder.

                        INCENTIVE STOCK OPTION AGREEMENT

        This Incentive Stock Option Agreement ("Option Agreement") is between
Castle Dental Centers, Inc., a Delaware corporation (the "Company"), and Phillip
T. Hamner ("Optionee"), who agree as follows:

        Section 1. INTRODUCTION. The Company has heretofore adopted the Castle
Dental Centers, Inc. Omnibus Stock and Incentive Plan (the "Plan") for the
purpose of providing eligible key employees and directors of the Company and its
Affiliates (as defined in the Plan) with increased incentive to render services,
to exert maximum effort for the business success of the Company and to
strengthen the identification of employees and directors with the shareholders.
The Company, acting through its Board of Directors (the "Board"), has determined
that its interests will be advanced by the issuance to Optionee of an incentive
stock option under the Plan.

        Section 2. OPTION. Subject to the terms and conditions contained herein,
the Company hereby irrevocably grants to Optionee the right and option
("Option") to purchase from the Company 5,000 shares of the Company's common
stock, $.001 par value ("Common Stock"), at a price of $5.00 per share, which is
deemed to be not less than the fair market value of the Common Stock at the date
of grant of this Option.

        Section 3. OPTION PERIOD. The Option herein granted may be exercised by
Optionee in whole or in part at any time during a five year period beginning on
May 31, 1997 (the "Option Period"), subject to the limitation that said Option
shall not be exercisable for more than a percentage of the aggregate number of
shares offered by this Option determined by the number of full years of
employment with the Company or its Affiliates from the effective date of
Optionee's grant, to the date of such exercise, in accordance with the following
schedule:

         Number of                                     Percentage of
         FULL YEARS                                SHARES PURCHASABLE

             1                                              20%
             2                                              40%
             3                                              60%
             4                                              80%

                                       -1-
<PAGE>
Notwithstanding anything in this Option Agreement to the contrary, the Board, in
its sole discretion, may waive the foregoing schedule of vesting and upon
written notice to Optionee, accelerate the earliest date or dates on which any
of the Options granted hereunder are exercisable.

        Section 4. PROCEDURE FOR EXERCISE. The Option herein granted may be
exercised by the delivery by Optionee of written notice to the Secretary of the
Company setting forth the number of shares of Common Stock with respect to which
the Option is being exercised. The notice shall be accompanied by, at the
election of the Optionee, (i) cash, cashier's check, bank draft, or postal or
express money order payable to the order of the Company, (ii) certificates
representing shares of Common Stock theretofore owned by Optionee duly endorsed
for transfer to the Company, (iii) an election by Optionee to have the Company
withhold shares of Common Stock issuable upon exercise of the Option, or (iv)
any combination of the preceding, equal in value to the aggregate exercise
price. Notice may also be delivered by telecopy provided that the exercise price
of such shares is received by the Company via wire transfer on the same day the
telecopy transmission is received by the Company. The notice shall specify the
name in which such shares are issued and the address to which the certificates
for such shares are to be mailed. An option to purchase shares of Common Stock
in accordance with this Plan, shall be deemed to have been exercised immediately
prior to the close of business on the date (i) written notice of such exercise
and (ii) payment in full of the exercise price for the number of shares for
which Options are being exercised, are both received by the Company and Optionee
shall be treated for all purposes as the record holder of such shares of Common
Stock as of such date.

        As promptly as practicable after receipt of such written notice and
payment, the Company shall deliver to Optionee certificates for the number of
shares with respect to which such Option has been so exercised, issued in
Optionee's name or such other name as Optionee directs; provided, however, that
such delivery shall be deemed effected for all purposes when a stock transfer
agent of the Company shall have deposited such certificates in the United States
mail, addressed to Optionee at the address specified pursuant to this Section 4.

        Section 5. TERMINATION OF EMPLOYMENT. If Optionee ceases to be employed
by the Company or its Affiliates for any reason other than death or disability,
any Option which is exercisable on the date of such termination of employment
shall expire upon such date of such termination of employment; provided,
however, the Board, in its sole discretion, may allow Optionee to exercise all
or a portion of the options granted but unexercised for a period of time after
Optionee's termination of employment.

        Section 6. DISABILITY OR DEATH. In the event that Optionee dies or is
determined to be disabled while Optionee is employed by the Company, the options
previously granted to Optionee may be exercised (to the extent Optionee would
have been entitled to do so at the date of death or the determination of
disability) at any time and from time to time, within a one-year period after
such death or determination of disability, by the Optionee, the guardian of
Optionee's estate, the executor or administrator of Optionee's estate or by the
person or persons to whom Optionee's rights under this Option Agreement shall
pass by will or the laws of descent and distribution, but in no event may

                                       -2-
<PAGE>
the Option be exercised after its expiration under the terms of this Option
Agreement. An Optionee shall be deemed to be disabled if, in the opinion of a
physician selected by the Board, Optionee is incapable of performing services
for the Company of the kind Optionee was performing at the time the disability
occurred by reason of any medically determinable physical or mental impairment
which can be expected to result in death or to be of long, continued and
indefinite duration. The date of determination of disability for purposes hereof
shall be the date of such determination by such physician.

        Section 7. TRANSFERABILITY. This Option shall not be transferable by
Optionee otherwise than by Optionee's will or by the laws of descent and
distribution or pursuant to a transfer which is incident to a divorce, as
described in Code Section 1041(a). During the lifetime of Optionee, the Option
shall be exercisable only by Optionee or his authorized legal representative.
Any heir or legatee of Optionee shall take rights herein granted subject to the
terms and conditions hereof. No such transfer of this Option Agreement to heirs
or legatees of Optionee shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and a copy of such
evidence as the Board may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions hereof.

        Section 8. NO RIGHTS AS SHAREHOLDER. Optionee shall have no rights as a
shareholder with respect to any shares of Common Stock covered by this Option
Agreement until the Option is exercised by written notice and accompanied by
payment as provided in Section 4 of this Option Agreement.

        Section 9. EXTRAORDINARY CORPORATE TRANSACTIONS. The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its shareholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issuance of Common Stock or subscription rights thereto, or any issuance of
bonds, debentures, preferred or prior preference stock ahead of or affecting the
Common Stock or the rights thereof, or the dissolution or liquidation of the
Company, or any sale or transfer of all or any part of its assets or business,
or any other corporate act or proceedings, whether of a similar character or
otherwise. If the Company goes through a "Fundamental Change" or a "Corporate
Change" (as defined in subsection 8.4 of the Plan), the Options granted
hereunder shall be governed by subsection 8.4 of the Plan.

        Section 10. CHANGES IN CAPITAL STRUCTURE. If the outstanding shares of
Common Stock or other securities of the Company, or both, for which the Option
is then exercisable shall at any time be changed or exchanged by declaration of
a stock dividend, stock split, combination of shares, or recapitalization, the
number and kind of shares of Common Stock or other securities subject to the
Plan or subject to the Option and the exercise price, shall be appropriately and
equitably adjusted so as to maintain the proportionate number of shares or other
securities without changing the aggre gate exercise price.

                                                                     Doc. No. 13

                           CASTLE DENTAL CENTERS, INC.
                        INCENTIVE STOCK OPTION AGREEMENT

        This Incentive Stock Option Agreement ("Option Agreement") is between
Castle Dental Centers, Inc., a Delaware corporation (the "Company"), and David
North ("Optionee"), who agree as follows:

        Section 1. INTRODUCTION. The Company has heretofore adopted the Castle
Dental Centers, Inc. Omnibus Stock and Incentive Plan (the "Plan") for the
purpose of providing eligible key employees and directors of the Company and its
Affiliates (as defined in the Plan) with increased incentive to render services,
to exert maximum effort for the business success of the Company and to
strengthen the identification of employees and directors with the shareholders.
The Company, acting through its Board of Directors (the "Board"), has determined
that its interests will be advanced by the issuance to Optionee of an incentive
stock option under the Plan.

        Section 2. OPTION. Subject to the terms and conditions contained herein,
the Company hereby irrevocably grants to Optionee the right and option
("Option") to purchase from the Company 5,000 shares of the Company's common
stock, $.001 par value ("Common Stock"), at a price of $5.00 per share, which is
deemed to be not less than the fair market value of the Common Stock at the date
of grant of this Option.

        Section 3. OPTION PERIOD. The Option herein granted may be exercised by
Optionee in whole or in part at any time during a five year period beginning on
May 31, 1997 (the "Option Period"), subject to the limitation that said Option
shall not be exercisable for more than a percentage of the aggregate number of
shares offered by this Option determined by the number of full years of
employment with the Company or its Affiliates from the effective date of
Optionee's grant, to the date of such exercise, in accordance with the following
schedule:

         Number of                                     Percentage of
         FULL YEARS                                SHARES PURCHASABLE

             1                                              20%
             2                                              40%
             3                                              60%
             4                                              80%
             5                                             100%

                                       -1-
<PAGE>
Notwithstanding anything in this Option Agreement to the contrary, the Board, in
its sole discretion, may waive the foregoing schedule of vesting and upon
written notice to Optionee, accelerate the earliest date or dates on which any
of the Options granted hereunder are exercisable.

        Section 4. PROCEDURE FOR EXERCISE. The Option herein granted may be
exercised by the delivery by Optionee of written notice to the Secretary of the
Company setting forth the number of shares of Common Stock with respect to which
the Option is being exercised. The notice shall be accompanied by, at the
election of the Optionee, (i) cash, cashier's check, bank draft, or postal or
express money order payable to the order of the Company, (ii) certificates
representing shares of Common Stock theretofore owned by Optionee duly endorsed
for transfer to the Company, (iii) an election by Optionee to have the Company
withhold shares of Common Stock issuable upon exercise of the Option, or (iv)
any combination of the preceding, equal in value to the aggregate exercise
price. Notice may also be delivered by telecopy provided that the exercise price
of such shares is received by the Company via wire transfer on the same day the
telecopy transmission is received by the Company. The notice shall specify the
name in which such shares are issued and the address to which the certificates
for such shares are to be mailed. An option to purchase shares of Common Stock
in accordance with this Plan, shall be deemed to have been exercised immediately
prior to the close of business on the date (i) written notice of such exercise
and (ii) payment in full of the exercise price for the number of shares for
which Options are being exercised, are both received by the Company and Optionee
shall be treated for all purposes as the record holder of such shares of Common
Stock as of such date.

        As promptly as practicable after receipt of such written notice and
payment, the Company shall deliver to Optionee certificates for the number of
shares with respect to which such Option has been so exercised, issued in
Optionee's name or such other name as Optionee directs; provided, however, that
such delivery shall be deemed effected for all purposes when a stock transfer
agent of the Company shall have deposited such certificates in the United States
mail, addressed to Optionee at the address specified pursuant to this Section 4.

        Section 5. TERMINATION OF EMPLOYMENT. If Optionee ceases to be employed
by the Company or its Affiliates for any reason other than death or disability,
any Option which is exercisable on the date of such termination of employment
shall expire upon such date of such termination of employment; provided,
however, the Board, in its sole discretion, may allow Optionee to exercise all
or a portion of the options granted but unexercised for a period of time after
Optionee's termination of employment.

        Section 6. DISABILITY OR DEATH. In the event that Optionee dies or is
determined to be disabled while Optionee is employed by the Company, the options
previously granted to Optionee may be exercised (to the extent Optionee would
have been entitled to do so at the date of death or the determination of
disability) at any time and from time to time, within a one-year period after
such death or determination of disability, by the Optionee, the guardian of
Optionee's estate, the executor or administrator of Optionee's estate or by the
person or persons to whom Optionee's rights under

                                       -2-
<PAGE>
this Option Agreement shall pass by will or the laws of descent and
distribution, but in no event may the Option be exercised after its expiration
under the terms of this Option Agreement. An Optionee shall be deemed to be
disabled if, in the opinion of a physician selected by the Board, Optionee is
incapable of performing services for the Company of the kind Optionee was
performing at the time the disability occurred by reason of any medically
determinable physical or mental impairment which can be expected to result in
death or to be of long, continued and indefinite duration. The date of
determination of disability for purposes hereof shall be the date of such
determination by such physician.

        Section 7. TRANSFERABILITY. This Option shall not be transferable by
Optionee otherwise than by Optionee's will or by the laws of descent and
distribution or pursuant to a transfer which is incident to a divorce, as
described in Code Section 1041(a). During the lifetime of Optionee, the Option
shall be exercisable only by Optionee or his authorized legal representative.
Any heir or legatee of Optionee shall take rights herein granted subject to the
terms and conditions hereof. No such transfer of this Option Agreement to heirs
or legatees of Optionee shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and a copy of such
evidence as the Board may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions hereof.

        Section 8. NO RIGHTS AS SHAREHOLDER. Optionee shall have no rights as a
shareholder with respect to any shares of Common Stock covered by this Option
Agreement until the Option is exercised by written notice and accompanied by
payment as provided in Section 4 of this Option Agreement.

        Section 9. EXTRAORDINARY CORPORATE TRANSACTIONS. The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its shareholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issuance of Common Stock or subscription rights thereto, or any issuance of
bonds, debentures, preferred or prior preference stock ahead of or affecting the
Common Stock or the rights thereof, or the dissolution or liquidation of the
Company, or any sale or transfer of all or any part of its assets or business,
or any other corporate act or proceedings, whether of a similar character or
otherwise. If the Company goes through a "Fundamental Change" or a "Corporate
Change" (as defined in subsection 8.4 of the Plan), the Options granted
hereunder shall be governed by subsection 8.4 of the Plan.

        Section 10. CHANGES IN CAPITAL STRUCTURE. If the outstanding shares of
Common Stock or other securities of the Company, or both, for which the Option
is then exercisable shall at any time be changed or exchanged by declaration of
a stock dividend, stock split, combination of shares, or recapitalization, the
number and kind of shares of Common Stock or other securities subject to the
Plan or subject to the Option and the exercise price, shall be appropriately and
equitably adjusted

                                       -3-
<PAGE>
so as to maintain the proportionate number of shares or other securities without
changing the aggre gate exercise price.

        Section 11. SHAREHOLDER AGREEMENT. Optionee, or Optionee's
representative upon Optionee's death, prior to the exercise of an Option granted
hereunder, agrees to enter into the Company's Shareholders Agreement at the
request of the Company.

        Section 12. COMPLIANCE WITH SECURITIES LAWS. Upon the acquisition of any
shares pursuant to the exercise of the Option herein granted, Optionee (or any
person acting under Section 7) will enter into such written representations,
warranties and agreements as the Company may reasonably request in order to
comply with applicable securities laws or with this Option Agreement.

        Section 13. COMPLIANCE WITH LAWS. Notwithstanding any of the other
provisions hereof, Optionee agrees that he or she will not exercise the Option
granted hereby, and that the Company will not be obligated to issue any shares
pursuant to this Option Agreement, if the exercise of the Option or the issuance
of such shares of Common Stock would constitute a violation by Optionee or by
the Company of any provision of any law or regulation of any governmental
authority.

        Section 14. NO RIGHT TO EMPLOYMENT. Optionee who is an employee shall be
considered to be in the employment of the Company so long as he or she remains
an employee of the Company or its Affiliates. Any questions as to whether and
when there has been a termination of such employment and the cause of such
termination shall be determined by the Board, and its determination shall be
final. Nothing contained herein shall be construed as conferring upon Optionee
the right to continue in the employ of the Company, nor shall anything contained
herein be construed or interpreted to limit the "employment at will"
relationship between Optionee and the Company.

        Section 15. RESOLUTION OF DISPUTES. As a condition of the granting of
the Option hereby, Optionee, and Optionee's heirs, personal representatives and
successors agree that any dispute or disagreement which may arise hereunder
shall be determined by the Board, in its sole discretion and judgment, and that
any such determination and any interpretation by the Board of the terms of this
Option Agreement shall be final and shall be binding and conclusive, for all
purposes, upon the Company, Optionee, and Optionee's heirs, personal
representatives and successors.

        Section 16. LEGENDS ON CERTIFICATE. The certificates representing the
shares of Common Stock purchased by exercise of the Option will be stamped or
otherwise imprinted with legends in such form as the Company or its counsel may
require with respect to any applicable restrictions on sale or transfer and the
stock transfer records of the Company will reflect stop-transfer instructions
with respect to such shares.

        Section 17. NOTICES. Every notice hereunder shall be in writing and
shall be given by registered or certified mail. All notices of the exercise of
any Option hereunder shall be directed to

Optionee shall be deemed to have familiarized himself or herself with all
matters contained herein and in the Plan which may affect any of Optionee's

shall notify the Company of such disposition within ten days of its occurrence
and deliver to the Company any amount of federal or state income tax withholding
required by law. Payment of the withholding shall be made in accordance with
Section 10 of the Plan. If the Optionee fails to pay the withholding tax, the
Company is authorized to withhold from any cash remuneration then or thereafter
payable to the Optionee any tax required to be withheld by reason of any
disposition named herein.

        Section 20. AGREEMENT SUBJECT TO PLAN. This Option Agreement is subject
to the Plan. The terms and provisions of the Plan (including any subsequent
amendments thereto) are hereby incorporated herein by reference thereto. In the

provision of the Plan, the applicable terms and provisions of the Plan will
govern and prevail. All definitions of words and terms contained in the Plan
