ITEM 1.    BUSINESS

THE COMPANY

        The Company develops, manages and operates integrated dental networks
through contractual 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. In January 1998, the Company
signed a definitive agreement to acquire 80% of a dental practice management
company in Los Angeles, California. The Company does not engage in the practice
of dentistry but rather establishes integrated dental networks by entering into
management services agreements with affiliated dental practices to provide on an
exclusive basis management and administrative services to affiliated dental
practices. The Company's strategy is to provide high-quality care in selected
markets 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 December 31, 1997, the
Company provided management services to 42 dental centers with 125 affiliated
dentists, orthodontists and other dental specialists.

        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
targeted 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's affiliated
dental practices currently maintain an aggregate of 20 capitated managed care
contracts covering approximately 55,000 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 on behalf of the
affiliated practices.

        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.

        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 10 locations
with 39 dentists in the Houston metropolitan area. During this period the
Company developed, implemented and refined the integrated dental network
approach that it intends to utilize as a basis for its national expansion.

        There presently are 13 Castle Dental Centers operating in the Houston,
Texas area and 3 additional centers in Houston in various stages of development.
In May 1996, the Company acquired the assets of and entered into long-term
management services agreements with 1st Dental Care, a dental practice with 11
locations in the Tampa/Clearwater, Florida area, and Mid-South Dental Centers, 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. In September 1997, the Company acquired SW Dental Associates, LC, a
dental practice with four dental centers in the Austin, 


                                       1
<PAGE>
Texas metropolitan area. In December 1997, the Company acquired substantially
all the assets of two individual practices in Ft. Worth, Texas and Nashville,
Tennessee. (All of the acquisitions are collectively referred to as the
"Completed Acquisitions.")

THE DENTAL INDUSTRY

        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 was estimated
by the Health Care Financing Administration, Health Care Financing Review (1995)
to be approximately $42.9 billion for 1995, representing approximately 4.3% 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 8.1% from
1980 to 1995, and is projected to grow at a compound annual growth rate of
approximately 6.3% 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 were 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 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 

                                       2
<PAGE>
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 a broad range of dental services through practice affiliations that
provide high-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 specialties (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 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 their 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 expansion of existing networks, as well as improve
        the utilization of existing facilities by providing a source of patients
        to dentists with whom the Company is affiliated. 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 the acquisition
of existing dental practices and the DE NOVO development of dental practices in
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.

</TABLE>

        *  Includes full-time and part-time dentists.

        The contractual arrangements pursuant to which the Completed
Acquisitions were made include representations and warranties from the sellers
regarding the assets being acquired, and employment agreements with the
affiliated practices containing noncompetition provisions with the former owners
of such practices. Additionally, the Company typically enters into an option
agreement with the owner of the affiliated dental practice which entitles the
Company to select successor owners of the affiliated dental practice.

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 as allowable by federal and state law; (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) requires that the affiliated dentists enter into employment agreements
with the affiliated practices 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 

                                       4
<PAGE>
permit, the Company initiates the process of converting the affiliated practice
into a Castle Dental Center. Management will retain the name of an affiliated
practice in situations where brand recognition has been established. This
conversion 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 operations, 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. The Company anticipates that it will enter into a
similar management services agreement 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. Subject to
applicable law, the Company is paid a monthly management fee comprised of three
components: (i) the costs incurred by it on behalf of the affiliated practice;
(ii) a base management fee in an amount ranging from 12.5% to 15.0% of adjusted
gross revenues; and (iii) a performance fee equal to the patient revenues of the
affiliated dental practice less (a) the expenses of the affiliated dental
practice and (b) the sum of (i) and (ii), as described in each agreement. 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 25
to 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.

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
employment agreements with substantially all 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 

                                       5
<PAGE>
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 permit and
to the extent deemed enforceable under applicable law, 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 $3.0
million in the 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 part-time dentists retained by the affiliated dental
practices are independent contractors and have entered into independent
contractor agreements.

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.

        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 to 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.

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 from four to 22 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 may seek to relocate such affiliated practice to a more desirable 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
specialties. The Company believes 

                                       6
<PAGE>
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 several centers in order to
utilize their time optimally. Each patient typically is assigned to and 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 Company's dental centers are staffed with patient care coordinators
who are responsible for the non-clinical aspects of the patient's experience
with the practice. The patient care coordinator's function is (i) to act as a
liaison between the dentist and patient; (ii) to work with the patient to
develop a treatment schedule with payments tailored to the patient's needs
within the Company's established credit policies; and (iii) to optimize 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
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 ranging
from $89 to $98 per month. After consultation with the patient care coordinator
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.

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. 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, the ability to offer career paths previously unavailable to dentists
and the ability to recruit for multiple markets 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.

        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 

                                       7
<PAGE>
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.

SALES AND MARKETING

        The Company intends to implement 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 that name recognition 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 to market its dental services
to potential patients in Houston, Texas and the Company intends to use the same
marketing techniques in its regional markets.

        The Company has also established a regional telemarketing system in
Houston and Austin, Texas to field calls generated by advertising, to confirm
upcoming scheduled patient visits and 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.

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 dental practice management companies, both
publicly-traded and privately owned, that are acquiring and managing dental
practices. Publicly-Traded dental practice management companies that compete
with the Company include Monarch Dental Corporation, Gentle Dental Service Corp.
and Coast Dental Services, Inc., as well as others. 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. The existence of other dental practice management companies may also
increase competition for acquisition candidates, thereby increasing amounts
that must be paid for acquired practice management businesses.

        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.

MANAGEMENT INFORMATION SYSTEMS

        The Company and its affiliated dental practices presently utilize two
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 management information 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 

                                       8
<PAGE>
headquarters. The Company intends to use its financial information system in
conjunction with existing practice management systems at the affiliated dental
practices.

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 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 Medicare, Medicaid or other
federal and state programs, 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 the Company's operations, 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 

                                       9
<PAGE>
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 from Medicare and Medicaid as
well as 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. The laws of
many states also prohibit dental practitioners from paying any portion of fees
received for dental services 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 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 the management
fees the Company charges for those services are consistent with the laws and
regulations of the jurisdictions in which it operates.

        In addition, there are certain regulatory risks associated with the
Company's role in negotiating and administering managed care and capitation
contracts. The application of state insurance laws to reimbursement arrangements
other than various types of fee-for-service arrangements is an unsettled area of
law and is subject to interpretation by regulators with broad discretion. As the
Company or its affiliated practices contract with third-party payors, including
self-insured plans, for certain non-fee-for-service basis arrangements, the
Company or the affiliated dental practices may become subject to state insurance
laws. In the event that the Company or the affiliated practices are determined
to 

                                       10
<PAGE>
be engaged in the business of insurance, these parties could be required
either to seek licensure as an insurance company or to change the form of their
relationships with third-party payors, and may become subject to regulatory
enforcement actions. In such events, 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 or marketing from time to time in response to changes in the
business, statutory and regulatory environments. The Company plans to structure
all of its agreements, operations and marketing in compliance 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.

EMPLOYEES

        As of December 31, 1997, the Company and its affiliated dental practices
employed approximately 625 administrative and dental office personnel on a
full-time or part-time basis, and the affiliated dental practices employed
approximately 100 general dentists and 25 specialists on a full-time or
part-time basis. As a component of its acquisition strategy, the Company
frequently enters into employment or consulting agreements for ongoing
management and administrative services 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.

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
$1.0 million for each occurrence and $3.0 million annual aggregate, and
professional liability coverage of not less than $1.0 million for each
occurrence and $3.0 million 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.

ITEM 2.    PROPERTIES

        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.

                                       11
<PAGE>
        All of the Company's existing centers are leased. Two of the centers 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
basis not less favorable to the Company than fair market value basis.

        The Company intends to lease centers or enter into build-to-suit
arrangements with third parties for dental centers to be leased 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 1998 and 2006 excluding options to renew.

        The majority of the 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.

ITEM 3.    LEGAL PROCEEDINGS


        In July and August 1997, a dentist from whom the Company acquired
Horizon Dental Centers in August 1996 contacted the Company asserting that the
Company misrepresented the value of the Common Stock issued to him as a part of
the consideration for the acquisition and demanded the issuance of approximately
200,000 shares of Common Stock as additional consideration for the transaction.
The Company believes that these asserted claims are without merit and has denied
the demand for the issuance of additional shares of Common Stock. In the event,
that litigation is initiated against the Company, the Company intends to defend
itself vigorously.

        The Company and certain of its subsidiaries are parties to a number of
legal proceedings that have arisen in the ordinary course of business. While the
outcome of these proceedings cannot be predicted with certainty, management does
not expect these matters to have a material adverse effect on the Company.

        The Company carries insurance with coverages and coverage limits that it
believes to be customary in the dental industry. Although there can be no
assurance that such insurance will be sufficient to protect the Company against
all contingencies, management believes that its insurance protection is
reasonable in view of the nature and scope of the Company's operations.

        As of March 26, 1998, there were 6,237,581 shares of the Company's
Common Stock outstanding held by approximately 150 stockholders of record. The
Company believes there are approximately 1,650 beneficial owners of the
Common Stock.

        The Company has never paid a cash dividend on its Common Stock. The
Company currently intends to retain earnings to finance the growth and
development of its business and does not anticipate paying any cash dividends on
the Common Stock in the foreseeable future. In addition, the Company's credit
facility (the "Credit Facility") permits the payment of dividends only to the
extent the Company maintains a specified minimum net worth. The Company's net
worth as of December 31, 1997 was approximately $31.1 million. Any future change
in the Company's dividend policy will be made at the discretion of the Company's
Board of Directors in light of the financial condition, capital requirements,
earnings and prospects of the Company and any restrictions under credit
agreements, as well as other factors the Board of Directors may deem relevant.

(1)     In periods prior to 1996, the Company operated as a dental service
        company and reported all of its revenues as patient revenues. Effective
        December 31, 1995, as part of a reorganization and recapitalization plan
        (the "Reorganization"), the Company provides practice management
        services to the affiliated dental practices, and, as a result, its net
        revenues beginning January 1, 1996 consist of amounts earned by the
        Company under the terms of its management services agreements with
        affiliated dental practices, which equal patient revenues less amounts
        retained by affiliated dental practices. Amounts retained by affiliated
        dental practices consist primarily of compensation paid to dental
        professionals, which were classified as expenses of the Company prior to
        the Reorganization.

(2)     In 1995, the Company expensed $2.6 million of deferred compensation in
        connection with the Reorganization.

(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. If all of the Company's
        operations had been subject to income taxes, net income (loss) would
        have been $546,000, $515,000 and ($1.7 million) for the years ended
        December 31, 1993, 1994 and 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 year ended December 31, 1996 and 1997.

(5)     The Company recorded a $1,930,000 non-cash dividend to accrete the
        Series A Convertible Preferred Stock and the Series C Convertible
        Preferred Stock to their estimated fair value.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 
        OF OPERATIONS

INTRODUCTION

        The Company develops, manages and operates integrated dental networks
through contractual affiliations with general, orthodontic and multi-specialty
dental practices in Texas, Florida and Tennessee. In January 1998, the Company
signed a definitive agreement to acquire 80% of a dental practice management
company in Los Angeles, California. The Company does not engage in the practice
of dentistry but rather establishes integrated dental networks through
affiliations with dental practices providing quality care in selected markets
with a view to establishing 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. At December 31, 1997, the Company
managed 42 dental centers with 125 affiliated dentists, orthodontists and
specialists.

        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 to the 

                                       15
<PAGE>
practice of dentistry, including situating practices in high-profile locations,
offering affordable fees and payment plans, expanding the range of services
offered, increasing market share through targeted 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 greater productivity than traditional retail
and small group dental practices.

        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.

COMPONENTS OF REVENUES AND EXPENSES

        Patient revenues from affiliated dental practices represent amounts
billed by the affiliated dental practices to patients and third-party payors for
dental services rendered. Such amounts also include monthly capitation payments
received from third-party payors pursuant to managed care contracts. Amounts
retained by group dental practices include compensation paid to dentists,
hygienists and other dental care personnel employed by the affiliated dental
practices, as well as other costs directly incurred by the affiliated practices
such as employment taxes, personnel benefits and insurance costs. Net revenues
represent amounts earned by the Company under the terms of its management
services agreements with the affiliated dental practices, which generally equal
patient revenues less amounts retained by the affiliated practices. The
Company's net revenues, therefore, are dependent upon patient revenues realized
by the affiliated practices as well as compensation and other expenses of the
affiliated practices.

        Under the terms of the typical management services agreement with an
affiliated dental practice, the Company becomes the exclusive manager and
administrator of all non-dental services relating to the operation of the
practice. The obligations of the Company include assuming responsibility for the
operating expenses incurred in connection with managing the dental centers.
These expenses include salaries, wages and related costs of non-dental
personnel, dental supplies and laboratory fees, rental and lease expenses,
advertising and marketing costs, management information systems, and other
operating expenses incurred at the dental centers. In addition to these
expenses, the Company incurs general and administrative expenses related to the
billing and collection of accounts receivable, financial management and control
of the dental operations, insurance, training and development, and other general
corporate expenditures. As compensation for its services under the typical
management services agreement and subject to applicable law, the Company is paid
a management fee comprised of three components: (i) the costs incurred by it on
behalf of the affiliated practice; (ii) a base management fee in an amount
ranging from 12.5% to 15.0% of adjusted gross revenues; and (iii) a performance
fee equal to the patient revenues of the affiliated dental practice less (a) the
expenses of the affiliated dental practice and (b) the sum of (i) and (ii).

RESULTS OF OPERATIONS

The following table sets forth the percentages of patient revenues represented
by certain items reflected in the Company's Statements of Operations. The
information that follows represents historical results of the Company and does
not include pre-acquisition results of the dental practices that the Company has
acquired. The Company acquired 1st Dental Care of Clearwater, Florida in May
1996, Mid-South Dental of Nashville, Tennessee in May 1996, Horizon Dental
Centers of Ft. Worth and Austin, Texas in August 1996 and Southwest Dental
Associates of Austin, Texas in September 1997, and two individual practices
located in Ft.Worth, Texas and Nashville, Tennessee in December 1997.

</TABLE>


YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

        PATIENT REVENUES OF AFFILIATED DENTAL PRACTICES - Patient revenues of
affiliated dental practices increased from $29.6 million for the year ended
December 31, 1996 to $46.2 million for the year ended December 31, 1997, an
increase of $16.6 million or 56%. Approximately $12.6 million of the increase
was attributable to the acquisitions of 1st Dental Care in Clearwater, Florida,
Mid-South Dental Centers in Nashville, Tennessee, and Horizon Dental Centers in
Ft. Worth and Austin, Texas, completed during 1996, and SW Dental Associates in
Austin, Texas, completed in September 1997. Patient revenues in Houston
increased from $18.6 million in 1996 to $20.5 million in 1997, primarily the
result of the opening of three new dental centers in Houston during 1997.

        AMOUNTS RETAINED BY AFFILIATED DENTAL PRACTICES - Amounts retained by
affiliated dental practices primarily consist of compensation paid to dentists,
orthodontists, hygienists and other dental care personnel employed by the
affiliated dental practice. For the year ended December 31, 1997, amounts
retained by affiliated dental practices were $14.8 million, an increase of $4.8
million, or 48.4% from the prior year, primarily resulting from the Completed
Acquisitions. Expressed as a percentage of patient revenues, amounts retained by
dental practices decreased from 33.7% in 1996 to 32.0% in 1997, primarily
resulting from improved productivity of the Company's dentists and dental
staffs.

                                       17
<PAGE>
        NET REVENUES - For the year ended December 31, 1997, net revenues were
$31.4 million, an increase of $11.8 million or 60.1%. The Completed Acquisitions
accounted for $8.2 million of the increase in net revenues. Expressed as a
percentage of patient revenues, net revenues increased from 66.3% in 1996 to
68.0% in 1997, primarily as a result of the percentage reduction in amounts
retained by dental practices.

        CLINICAL SALARIES - Clinical salaries increased from $4.2 million for
the year ended December 31, 1996 to $6.8 million for the year ended December 31,
1997, an increase of $2.6 million or 59.7%. The Completed Acquisitions accounted
for the increase in clinic employee salaries. Expressed as a percentage of
patient revenues, clinical salaries increased from 14.3% to 14.6% for the years
ended December 31, 1996 and 1997, respectively.

        DENTAL SUPPLIES AND LABORATORY FEES - Dental supplies and laboratory
fees increased from $3.1 million for the year ended December 31, 1996 to $4.3
million for the year ended December 31, 1997, an increase of $1.2 million or
39.0%. This increase resulted primarily from the Completed Acquisitions, which
incurred $1.2 million in dental supplies and laboratory expenses. Expressed as a
percentage of patient revenues, dental supplies and laboratory fees decreased
from 10.5% in 1996 to 9.4% in 1997, primarily resulting from the centralization
of the Company's purchasing function and the institution of national supply
agreements with certain vendors of dental supplies and laboratory work.

        RENT AND LEASE EXPENSE - Rent and lease expense increased from $1.6
million for the year ended December 31, 1996 to $2.6 million for the year ended
December 31, 1997, an increase of $1.0 million or 62.7%. Rental expense from the
acquisitions in Florida, Tennessee and Texas accounted for $765,000 of the
increase with the balance resulting from the opening of four new dental centers
in Houston in 1996 and 1997. Expressed as a percentage of patient revenues,
rental and lease expense increased from 5.4% in 1996 to 5.6% in 1997.

        ADVERTISING AND MARKETING - Advertising and marketing expense increased
from $1.5 million for the year ended December 31, 1996 to $2.0 million for the
year ended December 31, 1997, an increase of 33.6%. The Completed Acquisitions
accounted for all of the increase. Expressed as a percentage of patient
revenues, however, advertising and marketing costs decreased from 5.1% in 1996
to 4.4% in 1997 as the Completed Acquisitions generally had lower advertising
and marketing costs than the Company's operations in Houston. The Company plans
to increase advertising and marketing costs in the acquired markets on a
selective basis.

        DEPRECIATION AND AMORTIZATION - Depreciation and amortization increased
from $1.1 million for the year ended December 31, 1996 to $2.1 million for the
year ended December 31, 1997, an increase of $1.0 million or 96.0%, primarily
resulting from higher depreciation and amortization of goodwill related to the
Completed Acquisitions. As a percentage of patient revenues, depreciation and
amortization increased from 3.7% to 4.6% for the years ended December 31, 1996
and 1997, respectively.

        OTHER OPERATING EXPENSES - Other operating expenses increased from $2.9
million for the year ended December 31, 1996 to $4.3 million for the year ended
December 31, 1997, an increase of approximately $1.4 million or 48.1%. 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. The increase from 1996
to 1997 resulted from the Completed Acquisitions and the new dental centers
opened in Houston during 1997. Expressed as a percentage of revenues, however,
other operating expenses decreased from 9.8% to 9.3%, for the years ended
December 31, 1996 and 1997, respectively.

                                       18
<PAGE>
        GENERAL & ADMINISTRATIVE EXPENSE - General and administrative expenses
increased from $4.3 million for the year ended December 31, 1996 to $5.9 million
for the year ended December 31, 1997, an increase of $1.6 million or 38.2%. The
increase resulted from the addition of general and administrative expenses of
the Completed Acquisitions and increased personnel and general corporate
expenses at the Company's headquarters in Houston. Expressed as a percentage of
patient revenues, general and administrative expense, however, decreased from
14.6% to 12.8% for years ended December 31, 1996 and 1997, respectively, due to
relatively higher percentage increase in the Company's patient revenues.

        INTEREST EXPENSE - Interest expense increased from $2.6 million for the
year ended December 31, 1996 to $2.8 million for the year ended December 31,
1997, as a result of higher average borrowing levels and increased interest
rates in 1997. In September and October 1997, the Company repaid approximately
$23.9 million of its outstanding debt with the net proceeds of the initial
public offering of the Company's common stock.

        INCOME TAXES - For the year ended December 31, 1997, the Company
recorded a provision for income taxes of $200,000 resulting from income before
income taxes and extraordinary loss of $611,000. For the year ended December 31,
1996, the Company recorded a benefit for income taxes of $561,000 resulting from
the loss before income taxes of $1.6 million. The Company's average tax rate for
1997 was 30.3% as it realized some benefit from its net operating loss
carryforwards. At December 31, 1997, the Company had net operating loss
carryforwards available to reduce future taxable income of approximately $6.0
million expiring in 2017.

        EXTRAORDINARY LOSS - During 1997, the Company recorded an extraordinary
loss of $3.2 million, net of income tax benefit of $490,000, to record the write
off of deferred loan costs and unamortized discounts associated with early
retirement of the Company's 12% Senior Subordinated Notes in the aggregate
amount of $10.4 million, including accrued interest. The Senior Subordinated
Notes had been issued in December 1995 and in June 1997 in original principal
amounts of $7.5 million and $2.0 million, respectively, and were retired
utilizing a portion of the proceeds of the Company's initial public offering.

        PREFERRED STOCK DIVIDENDS - Coincident with the completion of the
initial public offering in September 1997, the holders of the Company's Series A
and Series C Preferred Stock converted such shares into an aggregate of 948,243
shares of Company Common Stock. As a result, the Company recorded $1.9 million
in non-cash dividends in the third quarter 1997, representing the accretion of
the difference between the recorded value of the Preferred Stock and its
redemption value.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

        PATIENT REVENUES OF AFFILIATED DENTAL PRACTICES -- Patient revenues of
affiliated dental practices increased from $18.3 million for the year ended
December 31, 1995 to $29.6 million for the year ended December 31, 1996, an
increase of $11.3 million or 62.1%. Approximately $11.0 million of the increase
was attributable to the Completed Acquisitions. Patient revenues in Houston
increased from $18.3 million in 1995 to $18.6 million in 1996, primarily the
result of the opening of the Company's ninth dental center in Houston in April
1996.

        AMOUNTS RETAINED BY AFFILIATED DENTAL PRACTICES -- For the year ended
December 31, 1996, amounts retained by affiliated dental practices were $10.0
million, or 33.7% of patient revenues. For the year ended December 31, 1995,
compensation paid to dental professionals was classified as dentist salaries and
clinical salaries. The Company estimates that amounts retained by the affiliated
dental practice in 1995, calculated on a basis comparable to 1996, was $5.2
million, or 28.6% of patient revenues. The percentage increase from 1995 to 1996
resulted from the relatively higher percentage of dentist and clinical salaries
from the Completed Acquisitions.

        NET REVENUES -- Net revenues of $19.6 million for the year ended
December 31, 1996 represent management fees earned by the Company in accordance
with management services agreements with the affiliated practices. In periods
prior to 1996, the Company's predecessor companies, Family Dental and 

                                       19
<PAGE>
Jack H. Castle D.D.S., Inc, operated as a combined entity, and did not
distinguish between patient revenues and net revenues.

        DENTISTS' SALARIES -- Compensation paid to dentists for the year ended
December 31, 1995 was $3.3 million, or 18.3% of patient revenues. Dentist
salaries in 1996, which are included in amounts retained by affiliated dental
practices, were $5.9 million, or 20% of patient revenues. Dentist salaries from
the 25 dental centers of the Completed Acquisitions accounted for $2.4 million
of the increase. The addition of one DE NOVO dental center and higher
compensation paid to dentists in Houston accounted for the balance of the
increase.

        CLINICAL SALARIES -- Clinical salaries increased from $1.9 million for
the year ended December 31, 1995 to $4.2 million for the year ended December 31,
1996, an increase of $2.4 million or 125.3%. The Completed Acquisitions
accounted for the increase in clinic employee salaries. Expressed as a
percentage of patient revenues, clinical salaries increased from 10.3% to 14.3%
for the years ended December 31, 1995 and 1996, respectively, as the Completed
Acquisitions had relatively higher percentage clinical salaries costs than the
Houston operations.

        DENTAL SUPPLIES AND LABORATORY FEES -- Dental supplies and laboratory
fees increased from $2.2 million for the year ended December 31, 1995 to $3.1
million for the year ended December 31, 1996, an increase of $935,000 or 42.8%.
This increase resulted primarily from the Completed Acquisitions, which incurred
$1.1 million in dental supplies and laboratory expenses. Expressed as a
percentage of patient revenues, dental supplies and laboratory fees decreased
from 12.0% in 1995 to 10.5% in 1996.

        RENTAL AND LEASE EXPENSE -- Rental and lease expense increased from
$836,000 for the year ended December 31, 1995 to $1.6 million for the year ended
December 31, 1996, an increase of 90.4%. Rental expense from the Completed
Acquisitions accounted for nearly all of the increase. Expressed as a percentage
of patient revenues, rental and lease expense increased from 4.6% in 1995 to
5.4% in 1996, as the Completed Acquisitions had relatively higher percentage
rental and lease expense than the Houston operation.

        ADVERTISING AND MARKETING -- Advertising and marketing expense increased
from $1.0 million for the year ended December 31, 1995 to $1.5 million for the
year ended December 31, 1996, an increase of 58.7%. The Completed Acquisitions
accounted for $420,000 of the increase. Higher expenditures for television
advertising and direct mail campaigns conducted in conjunction with the opening
of two new dental centers in Houston resulted in increased advertising and
marketing costs of approximately $150,000 in Houston. Expressed as a percentage
of patient revenues, however, advertising and marketing costs decreased from
5.3% in 1995 to 5.1% in 1996.

        DEPRECIATION AND AMORTIZATION -- Depreciation and amortization increased
from $336,000 for the year ended December 31, 1995 to $1.1 million for the year
ended December 31, 1996, an increase of approximately $752,000, primarily
resulting from the Completed Acquisitions and amortization of deferred loan
costs incurred in connection with the Reorganization in December 1995.
Amortization of intangibles incurred in the period following the completion of
the acquisitions was $231,000 in 1996. As a percentage of patient revenues,
depreciation and amortization increased from 1.8% to 3.7% for the years ended
December 31, 1995 and 1996, respectively.

        OTHER OPERATING EXPENSES -- Other operating expenses increased from $2.3
million for the year ended December 31, 1995 to $2.9 million for the year ended
December 31, 1996, an increase of $653,000 or 28.9%. 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. The Completed Acquisitions accounted for all of
the increase in other operating expenses from 1995 to 1996. Expressed as a
percentage of patient revenues, other operating expenses decreased from 12.4% to
9.8% for the years ended December 31, 1995 and 1996, respectively, 

                                       20
<PAGE>
primarily due to the lower percentage of bad debt expense of the Completed
Acquisitions as compared to the Houston dental centers.

        GENERAL AND ADMINISTRATIVE -- General and administrative expense
decreased from $9.1 million for the year ended December 31, 1995 to $4.3 million
for the year ended December 31, 1996, a decrease of $4.8 million or 52.9%.
Compensation paid to the Company's owners was $5.3 million in 1995 including
$2.6 million in accrued deferred compensation payable to a shareholder.
Compensation to stockholders declined to $592,000 in 1996. This reduction was
partially offset by general and administrative expense of $1.2 million from the
Completed Acquisitions. In addition, the Company incurred approximately $400,000
in 1996 related to potential acquisitions that were not completed and
approximately $200,000 in personnel severance costs. Expressed as a percentage
of patient revenues, general and administrative expense decreased from 49.9% to
14.4% for years ended December 31, 1995 and 1996, respectively.

        INTEREST EXPENSE -- Interest expense increased from $87,000 for the year
ended December 31, 1995 to $2.6 million for the year ended December 31, 1996. In
the period from December 1995 through August 1996, the Company borrowed
approximately $25.0 million in order to fund the Reorganization and the
acquisition of affiliated dental practices in Florida, Tennessee and Texas,
resulting in $2.1 million in higher interest costs in 1996. In addition, the
amortization of the discount on the Senior Subordinated Notes was $522,000 for
the year ended December 31, 1996.

        INCOME TAXES -- Prior to 1996, the Company did not accrue significant
corporate income taxes because a major portion of the Company's operations were
conducted through a Subchapter S corporation. Subsequent to the Reorganization
in December 1995, all of the Company's operations became subject to corporate
income taxes. For the year ended December 31, 1996 the Company recorded a
benefit for income taxes of $561,000, related to the loss before taxes of $1.6
million for the year. At December 31, 1996, the Company had net tax loss
carryforwards of $2.1 million, which may be used in future periods to offset
taxable income.

LIQUIDITY AND CAPITAL RESOURCES

        Since 1996, the Company has relied on cash flow from operations and
third party borrowings to finance its operations, and on a combination of third
party borrowings, the issuance of Company common stock and seller notes payable,
and the assumption of certain debt and lease obligations to finance its
acquisitions.

        At December 31, 1997, the Company had net working capital of $3.9
million, representing an increase of $7.2 million from the net working capital
deficit of $3.2 million at December 31, 1996. Current assets consisted of cash
of $2.9 million, billed and unbilled accounts receivable of $8.4 million and
other current assets of $838,000. These were partially offset by current
liabilities of $8.2 million at December 31, 1997, consisting primarily of $2.6
million in current maturities of long-term debt, $4.9 million in accounts
payable and accrued liabilities, $658,000 in accrued deferred compensation
payments.

        For the year ended December 31, 1997, net cash used in operating
activities was approximately $502,000. Cash used in investing activities in 1997
totaled approximately $6.5 million. Cash provided by financing activities
amounted to approximately $9.8 million. Significant components of cash used in
operations included net income before extraordinary item and other non-cash
adjustments of $5.3 million offset by increased patient and unbilled patient
receivables of $4.7 million and decreased liabilities of $385,000. These changes
resulted primarily from the addition of new dental centers, increased
orthodontic revenues and a reduction in accounts payable. Significant components
of cash used in investing activities included $5.0 million to complete the
acquisition of SW Dental Associates located in Austin, Texas and $1.5 million in
capital expenditures used primarily to develop three de novo dental centers in
Houston, Texas and to upgrade the Company's practice management software.
Significant

                                       21
<PAGE>
components of cash provided by financing activities included net proceeds of
$33.7 million from the initial public offering of the Company's common stock in
September 1997 and $2.0 million in additional subordinated debt partially offset
by debt reductions totaling $24.4 million. Significant debt reductions included
$10.4 million in Senior Subordinated Debt, $9.1 million due under the Company's
bank credit facility and $4.4 million in subordinated seller notes. In
connection with the repayment of $10.4 million of 12% Senior Subordinated Notes,
the Company recognized a $3.2 million extraordinary loss, net of income tax
benefit, associated with the early retirement of such debt.

        For the year ended December 31, 1996 cash provided by operations was
$446,000. Cash used in investing activities in 1996 was $11.6 million,
consisting primarily of $10.3 million to acquire three group dental practices in
Florida, Tennessee and Texas, and of capital expenditures of $730,000 to develop
two de novo dental centers in Houston. Cash provided by financing activities was
$4.8 million for the year ended December 31, 1996 and consisted of bank
borrowings of $7.3 million, offset by debt repayments of $1.5 million and
prepaid offering and debt issuance costs of $908,000.

        During 1996, the Company financed its acquisitions, capital expenditures
and working capital requirements through a combination of borrowings under its
bank credit facility, the sale of senior subordinated notes, the issuance of
common stock and subordinated seller notes, and the assumption of certain debt
and lease obligations of the acquired dental practices. In the aggregate, the
total consideration for acquisitions made in 1996 consisted of $9.3 million in
cash, $894,000 of assumed debt and capital lease obligations, $4.5 million in
subordinated seller notes and 331,996 shares of Company common stock. During
1997, the Company acquired two dental practices in Texas and one in Tennessee
for total consideration of $10.2 million, consisting of $5.5 million in cash,
$138,000 of assumed debt and capital lease obligations, 119,231 shares of Series
B Convertible Preferred Stock, $1.4 million in seller notes, and 165,000 shares
of Company common stock. The Company paid the $1.5 million seller note on
January 5, 1998, utilizing proceeds from borrowings under its bank credit
facility.

        On September 17, 1997, the Company received approximately $30.3 million
in net proceeds from the initial public offering of 2,500,000 shares of Company
Common Stock at $13.00 per share. In October 1997, the underwriter's exercised
the overallotment option and the Company received an additional $3.4 million in
net proceeds from the issuance of 284,000 shares of Company Common Stock at
$13.00 per share.

        The Company's principal sources of liquidity as of December 31, 1997
consisted of cash and cash equivalents, net accounts receivable and borrowing
availability under the Company's bank credit facility. In November 1997, the
Company entered into a new Credit Agreement with its existing bank and
refinanced the outstanding balance due under the previous bank credit facility.
The Credit Agreement initially provided for borrowings up to $25.0 million and
matures November 2002. The principal balance of $3.0 million under the bank
credit facility at November 7, 1997 is payable in 16 quarterly payments
beginning in March 1998. Future advances under the bank credit facility require
quarterly interest payments through November 1999 when principal becomes payable
based on a five-year amortization and a final payment at maturity. Borrowings
under the bank credit facility may at no time exceed a specified borrowing base,
which is calculated as a multiple of the Company's earnings before taxes,
depreciation and amortization ("EBITDA"), as adjusted. The bank credit facility
bears interest at variable rates, which are based upon either the bank's base
rate or LIBOR, plus, in either case, a margin which varies according to the
ratio of the Company's funded debt to the EBITDA, each as defined in the bank
credit facility. A commitment fee is payable quarterly at rates ranging from
0.125 percent to 0.5 percent of the unused amounts for such quarter. The bank
credit facility contains affirmative and negative covenants that require that
Company to maintain certain financial ratios, limit the amount of additional
indebtedness, limit the creation or existence of liens, set certain restrictions
on acquisitions, mergers and sales of assets and restrict the payment of
dividends. At December 31, 1997, $3.0 million was outstanding under the bank
credit facility. In January 1998, the Company borrowed $1.5 million under the
bank credit facility that was used to repay certain short-term notes payable. In
February 1998, 

                                       22
<PAGE>
the Company and the Bank amended the bank credit facility and increased the
available borrowing to $42.5 million.

        In March 1998, the Company entered into definitive agreements to acquire
two dental practice management companies located in Houston, Texas and Los
Angeles, California. The acquisitions consist of a combination of cash, notes,
common stock and assumed indebtedness, totaling approximately $22.5 million. The
Company currently expects to acquire additional dental practice management
companies and dental practices in 1998. The Company anticipates that the
consideration for future acquisitions will consist of a combination of cash,
borrowings under the Company's bank credit facility, the issuance of Company
common stock and the assumption of existing indebtedness of the acquired
business. The Company anticipates making ongoing capital expenditures of
approximately $3.0 million in 1998, primarily to develop new dental centers in
its existing markets.

        Management believes that cash flow from operations and borrowings
available under the bank credit facility should be sufficient to meet its
anticipated capital expenditures and other operating requirements and to fund
anticipated acquisitions for the next 12 months. However, because future cash
flows and the availability of financing are subject to a number of variables,
such as the number and size of acquisitions made by the Company, the Company's
financial performance and other factors, there can be no assurance that the
Company's capital resources will be sufficient to maintain currently planned
levels of capital expenditures or to fund future acquisitions. Additional debt
and equity financing may be required in connection with future acquisitions. The
availability of these capital sources will depend on prevailing market
conditions and interest rates and the then-existing financial condition of the
Company.

YEAR 2000

        The year 2000 issue is the result of computer programs using two digits
to define the applicable year rather than four. Any programs that have time
sensitive software may recognize a date using "00" as the year 1900 rather than
the year 2000. A computer system which is not year 2000 compliant would not be
able to correctly process certain data, or, in extreme situations, system
failure could result.

        As part of the Company's continuing program to update its information
systems in anticipation of future growth, the Company has recently completed the
purchase and installation of year 2000 compliant software for its operations.
The Company is also currently evaluating software systems for its operations and
expects to have year 2000 compliant software in place by the end of 1998.
Accordingly, the Company does not expect the year 2000 issue to have a material
effect on its financial position, results of operations or cash flows.

INFLATION

        Inflation has not had a significant impact on the results of operations
of the Company during the last three years.

RECENTLY ISSUED PRONOUNCEMENTS

        In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income ("SFAS 130") and Statement of Financial Accounting Standards No. 131,
Disclosures About Segments of an Enterprise and Related Information ("SFAS
131"). SFAS No. 130 establishes standards for reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. SFAS 131 establishes standards for the way that public
enterprises report segment information in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial reports to shareholders. These statements are both
effective for fiscal years beginning after December 15, 1997. The Company does
not believe implementation of SFAS 130 and 131 will have a material effect on
its financial position, results of operation or cash flows.

ITEM 13.   CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        In September 1997, Mr. G. Daniel Siewert, the Company's President and
Chief Operating Officer, received a $130,000 loan from the Company in connection
with his employment agreement. The loan does not bear interest.

        Mr. Kahle, a director of the Company, is a Managing Director of The
GulfStar Group, Inc., which has provided investment banking and advisory
services to the Company. In 1995, the Company paid $540,000 in investment
banking fees to The GulfStar Group, and issued the GulfStar Warrant for 56,579
shares of Common Stock to GulfStar Investments, Ltd. The Company has paid The
GulfStar Group, Inc. for investment banking and financial advisory services
provided to the Company in an amount equal to one percent of the total
consideration for each of the Company's acquisitions which has been consummated.
The GulfStar Group received approximately $195,000 in investment banking and
financial advisory fees from the Company in 1996. The directors of the Company
other than Mr. Kahle approve the payments made to The GulfStar Group, Inc. by
the Company.

        Mr. Cresci, a director of the Company, is a Managing Director of Pecks
Management Partners Ltd., the investment advisor to the Pecks Investors, which
held in the aggregate 1,244,737 shares of Series A Convertible Preferred Stock
and 485,382 shares of Series C Convertible Preferred Stock and the Senior
Subordinated Notes. Upon completion of the Company's initial public offering in
September 1997, the Series A and Series C Convertible Preferred Stock was
converted into 948,243 shares of Common Stock. Pursuant to the provisions of the
Securities Purchase Agreement, for so long as certain ownership thresholds with
respect to the Common Stock are maintained, these investors have the contractual
right to nominate one member of the Company's Board of Directors. See
"Management -- Directors and Executive Officers."

        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 $6.0 million in cash and entered into a Deferred
Compensation Agreement with Dr. Castle pursuant to which the Company has agreed
to pay 

                                       25
<PAGE>
Dr. Castle $2.6 million in 20 quarterly installments beginning March 1996. 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.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Castle Dental Centers, Inc.:

We have audited the accompanying balance sheets of Castle Dental Centers, Inc.
as of December 31, 1996 and 1997, and the related statements of operations,
changes in stockholders' equity (deficit) and cash flows for each of the two
years in the period ended December 31, 1997 and the related statement of
operations, changes in stockholders' equity (deficit) and cash flows of its
combined predecessor companies for the year 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 Castle Dental Centers, Inc. as
of December 31, 1996 and 1997, and the results of its operations and its cash
flows for the two years in the period ended December 31, 1997 and the results of
operations and cash flows of its combined predecessor companies for the year
ended December 31, 1995, in conformity with generally accepted accounting
principles.

CASTLE DENTAL CENTERS, INC.
NOTES TO FINANCIAL STATEMENTS

1. CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

CORPORATE ORGANIZATION AND BASIS OF PRESENTATION

Castle Dental Centers, Inc. and subsidiaries (the "Company") provide
administrative and management services, non-healthcare personnel, facilities and
equipment to certain professional corporations in Texas, Florida and Tennessee
under long-term management services 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 equipment,
facilities, administrative personnel and management services, in exchange for a
contracted management fee based on a formula. Each of these agreements is for an
initial term of 25 to 40 years with successive automatic five year renewal
terms, unless terminated at least 90 days before the end of the initial term or
any renewal term.

Through the management services agreement, the Company generally 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 generally 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).

1. CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, 
   CONTINUED:

CORPORATE ORGANIZATION AND BASIS OF PRESENTATION, CONTINUED

The Company was formed in December 1995 and merged with Family Dental Services
of Texas, Inc. ("FDS"), a company wholly owned by members of the family of and
entities controlled by Jack H. Castle, D.D.S. (the "Castle Family"). The
Company's operations began on January 1, 1996. Simultaneously with this
transaction, the Company paid $6,000,000 to acquire all of the outstanding stock
of Jack H. Castle, D.D.S., Inc. ("JCD"), a professional corporation of which Dr.
Jack H. Castle was the sole owner. JCD provided dental care to patients from
1949 through December 31, 1995. FDS had been established in 1981 to carry out
administrative functions for the professional corporation and had no business
other than providing administrative services to JCD. All of FDS's revenues
consisted of reimbursement of its costs incurred on behalf of JCD. Effective
with the acquisition, JCD ceased to operate as a separate entity, and a new
professional corporation, Jack H. Castle, D.D.S., P.C. ("PC") was established to
continue the dental practice previously operated by JCD. Therefore, at December
31, 1995, the Company's financial statements included both the operations and
assets of FDS, the administrative and management services company, and JCD, the
professional corporation (together the "predecessor companies"). The combined
statements of operations, changes in stockholders' deficit and cash flows for
the year ended December 31, 1995 reflect the combined operations of predecessor
companies because these entities' activities were assumed by the Company and the
PC and they were under common control. All of the services provided by FDS to
JCD have been eliminated in combination of the predecessor companies' financial
statements.

In 1997, the Emerging Issues Task Force released Issue No. 97-2 "Application of
FASB statement No. 94, Consolidation of all Majority-Owned Subsidiaries, and APB
Opinion No. 16, Business Combinations, to Physician Practice Management Entities
And Certain Other Entities With Contractual Management Arrangements ("Issue No.
97-2).

Issue 97-2 allows consolidation by the physician practice management company
(the "PPM") with the affiliated physician practice when the PPM has controlling
financial interest through a contractual management arrangement. The Company's
management services agreement meet the criteria of Issue 97-2. The Company has
adopted the provisions of Issue 97-2 and retroactivity restated prior periods
based on the terms of the agreements that were in effect during the prior
periods.

At December 31, 1996 and 1997, and for the years ended December 31, 1996 and
1997, the consolidated financial statements include Castle Dental Centers, Inc.
and its wholly-owned management company subsidiaries and the affiliated
professional corporations.

All intercompany accounts and transactions have been eliminated in
consolidation. Certain reclassifications of prior years have been made to
conform to current period classifications.

REVENUE RECOGNITION

Patient revenues from affiliated dental practices ("Patient Revenues") represent
the estimated realizable amounts to be received from patients, third-party
payors and others for services rendered by affiliated dentists. Patient Revenues
from general dentistry are recognized as the services are performed. Patient
Revenues from orthodontic services are recognized in accordance with the
proportional performance method. Under this method, revenue is recognized as
services are performed 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 24 months, are made
equally throughout the term of the contract, with final payment at the
completion of the treatment.

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, 
    CONTINUED:

REVENUE RECOGNITION, CONTINUED

Amounts retained by affiliated dental practices consist primarily of
compensation paid to dental professionals, including dentists, orthodontists,
hygienists, and other medical personnel.

Net revenues represent management fees earned by the Company in accordance with
management services agreements with the affiliated dental practices and are
generally equal to Patient Revenues less amounts retained by affiliated dental
practices.

The management services fee charged to affiliated dental practices is comprised
of three components: (1) the reimbursable expenses of the Company, (2) a base
management fee ranging from 12.5% to 15.0% of net patient revenues of the
affiliated dental practices and (3) a performance fee equal to the patient
revenues of the affiliated dental practice less (a) the expenses of the
professional corporation and (b) the reimbursable expenses and base management
fees comprised of (1) and (2) above, if any.

Accounts receivable consist primarily of receivables from patients, insurers,
government programs and contracts between the affiliated dental practices and
third-party payors for dental services provided by dentists. The Company does
not believe that change in the reimbursement arrangements for its affiliated
dental practice contracts with third-party payors would have a material impact
on management fee revenues. An allowance for doubtful accounts is recorded by
the Company based on historical experience.

CASH AND CASH EQUIVALENTS

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

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation is 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 in use as of December 31, 1996 and 1997 were approximately
$950,000 and $1,062,000, respectively. Maintenance and repairs are charged to
expense whereas renewals and major replacements are capitalized. Gains and
losses from dispositions are included in operations.

1. CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, 
   CONTINUED:

INTANGIBLE ASSETS

The Company's acquisitions involve the purchase of tangible and intangible
assets and the assumption of certain liabilities of the affiliated dental
practices. As part of the purchase allocation, the Company allocates the
purchase price to the tangible assets acquired and liabilities assumed, based on
estimated fair market values. In connection with each acquisition, the Company
enters into a long-term management services agreement with each affiliated
dental practice, which cannot be terminated by either party without cause. The
cost of the management services agreement is amortized on a straight line basis
over its term, or such shorter period as may be indicated by the facts and
circumstances, as described below. Amortization periods of the management
services agreements acquired through December 31, 1997, are 25 years.

In connection with the allocation of the purchase price to identifiable
intangible assets, the Company analyzes the nature of the group with which a
management services agreement is entered into, including the number of dentists
in each group, number of dental centers and ability to recruit additional
dentists, the affiliated dental practice's relative market position, the length
of time each affiliated dental practice has been in existence, and the term and
enforceability of the management services agreement. Because the Company does
not practice dentistry, maintain patient relationships, hire dentists, enter
into employment and noncompete agreements with the dentist, or directly contract
with payors, the intangible asset created in the purchase allocation process is
associated solely with the management services agreement with the affiliated
dental practice.

The Company reviews intangible assets for impairment whenever events or changes
in circumstances indicate that the carrying amount of the asset may not be
recoverable. If this review indicates that the carrying amount of the asset may
not be recoverable, as determined based on the undiscounted cash flows of the
related operations over the remaining amortization period, the carrying value of
the asset is reduced to estimated fair value. Among the factors that the Company
will continually evaluate are unfavorable changes in each affiliated dental
practice's relative market share and local market competitive environment,
current period and forecasted operating results and cash flows of the affiliated
dental practice and its impact on the management fee earned by the Company, and
legal factors governing the practice of dentistry.

OTHER ASSETS

Other assets consist primarily of debt issuance costs and other receivables. The
costs related to the issuance of debt are capitalized and amortized using the
effective interest method over the lives of the related debt. The Company
provided a non-interest bearing loan for $130,000 to an officer which is
outstanding at December 31, 1997.

1.  CORPORATE ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, 
    CONTINUED:

INCOME TAXES

Prior to January 1, 1996, 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. If all of the Company's operations had been
subject to income taxes, net loss for the year ended December 31, 1995, would
have been $1.7 million.

The Company accounts for income taxes 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.

EARNINGS PER SHARE

In June 1997, the Company's Board of Directors declared and the stockholders
approved a 1-for-2 reverse split of the Company's common stock. All share and
per share information in the accompanying financial statements has been
retroactively restated to reflect the effects of the reverse stock split. The
Company adopted the provisions of SFAS No. 128 "Earnings per Share," effective
January 1, 1997. All prior periods presented have been restated to conform to
the new requirements.

ADVERTISING

Costs incurred for advertising are expensed when incurred.

PREOPENING COST

Costs incurred prior to opening a dental center, primarily salaries and lease
expense, are expensed when incurred.

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.

RECENTLY ISSUED PRONOUNCEMENTS

In June 1997, the FASB issued Statement of Financial Accounting Standards No.
130, Reporting Comprehensive Income ("SFAS 130") and Statement of Financial
Accounting Standards No. 131, Disclosures About Segments of an Enterprise and
Related Information ("SFAS 131"). SFAS 130 establishes standards for reporting
and display of comprehensive income and its components in a full set of general
purpose financial statements. SFAS 131 establishes standards for the way that
public enterprises report segment information in annual financial statements and
requires that those enterprises report selected information about operating
segments in interim financial statements to shareholders. These statements are
both effective for fiscal years beginning after December 15, 1997. The Company
does not believe implementation of SFAS 130 and 131 will have a material effect
on its financial position, results of operation or cash flows.

2.  REORGANIZATION AND RELATED TRANSACTIONS:

In December 1995, the Company completed a reorganization (the "Reorganization")
by (i) entering into a credit agreement that included a $3,000,000 revolving
line of credit and a $6,000,000 bank term loan (the "Bank Credit Facility"),
(ii) issuing $7,500,000 face amount of senior subordinated notes (the "Senior
Subordinated Notes") together with 1,244,737 shares of Series A Convertible
Preferred Stock (the "Series A Stock") and (iii) issuing 2,000,000 shares of
common stock to the former owner of JCD and certain related parties. A portion
of the proceeds from the Reorganization was used to acquire JCD, which
acquisition was recorded as a capital distribution to JCD's shareholder because
the Company and JCD were under common control. The Company applied these common
shares to a stock split.

In connection with the purchase of the stock of JCD, the Company entered into a
deferred compensation agreement (the "Deferred Compensation Agreement") with the
sole shareholder of JCD, who is a director of the Company, pursuant to which the
Company agreed to pay the shareholder $2,630,000 in 20 quarterly installments
beginning March 1996. The Company accrued the entire liability under the
agreement in December 1995 through a charge to compensation to shareholders.
Amounts not paid when scheduled under the original Deferred Compensation
Agreement bear interest at the rate of ten percent per year. As of December 31,
1997, there was $1,710,000 payable to the sole shareholder of JCD.

A warrant to purchase 56,579 shares of common stock at an exercise price of
$11.00 per share was issued to an investment advisor in connection with the
Reorganization. The warrant is exercisable at any time prior to its expiration
date of December 18, 2000.

                                      F-12
<PAGE>
2.  REORGANIZATION AND RELATED TRANSACTIONS, CONTINUED:

In September and October 1997, the Company completed an initial public offering,
including the underwriters' overallotment, of 2,784,000 shares of its common
stock at $13.00 per share. Proceeds of $31.7 million, net of underwriting
commission and offering expenses of $1,913,000, were used primarily to retire
debt and complete the SW Dental Associates, LC ("SW Dental") acquisition.

Coincident with the completion of the initial public offering, the holders of
1,244,737 shares of Series A and 485,382 shares of Series C Preferred Stock
converted such shares into an aggregate of 948,243 shares of Company common
stock. During the year ended December 31, 1997, the Company recorded
approximately $1.9 million in non-cash dividends which represents the accretion
of the difference between the recorded value of the Preferred Stock and the
redemption value. As of December 31, 1997, there were no shares of the Series A
Stock and Series C Convertible Preferred Stock (the "Series C Stock")
outstanding.

4.  ACQUISITIONS:

In May 1996, the Company acquired substantially all of the assets and assumed
certain liabilities of 1st Dental Care and Mid-South Dental Centers, group
dental practices headquartered in Clearwater, Florida, and Nashville, Tennessee,
respectively. In August 1996, the Company acquired substantially all of the
assets and assumed certain liabilities of five dental practices and acquired the
stock of three dental practices operated by Horizon Dental Centers, a group
dental practice with offices in Austin and Ft. Worth, Texas.

The aggregate purchase price, including the payment of certain assumed debt and
related acquisition expenses, of $18.2 million consisted of $10.3 million in
cash, $4.6 million in seller notes payable (Note 5) and 332,000 shares of
Company common stock with a fair market value of $3.3 million. In connection
with these acquisitions, the Company entered into employment agreements with
certain employees and former owners of the businesses acquired and into
long-term management services agreements with each of the affiliated dental
practices.

4. ACQUISITIONS, CONTINUED:

In June 1997, the Company entered into a management services agreement and
option agreement to acquire all of the membership interest in SW Dental, a group
dental practice located in Austin, Texas. In September 1997, the Company
completed the acquisition. In December 1997, the Company acquired substantially
all the assets of two individual practices in Ft. Worth, Texas and Nashville,
Tennessee and entered into employment agreements with the dentists. The
aggregate purchase price, including related acquisition expenses, of
approximately $10.2 million consisted of $5.5 million in cash, $1.5 million in
Series B Preferred Stock (Note 6), $1.4 million in sellers notes payable (Note
5) and 165,000 shares of the Company common stock with a fair market value of
approximately $1.7 million. The cash portion included $1.5 million in previously
paid non-refundable deposits of which $500,000 was in escrow at December 31,
1996.

The assets and liabilities have been recorded at their estimated fair values at
the date of acquisition. The aggregate purchase price and related expenses
exceeded the fair market value of net assets, which has been assigned to
management services agreements, included in intangible assets. Patient Revenues,
management fees and related costs are included in the consolidated financial
statements from their acquisition dates.

The estimated fair value of assets acquired and liabilities assumed are
summarized as follows:

5. REVOLVING LINE OF CREDIT AND LONG-TERM DEBT, 
   CONTINUED:

In November 1997, the Company entered into a new credit agreement with its
existing bank (the "Credit Agreement") and refinanced the outstanding balance
of $3.0 million due under the previous Bank Credit Facility. The Credit
Agreement provides for borrowings up to $25 million and matures November 2002.
The principal balance of $3.0 million due under the Credit Agreement at November
7, 1997 is payable in sixteen quarterly payments beginning March 1998. Future
advances under the Credit Agreement require quarterly interest payments through
November 1999 when principal becomes payable based on a five-year amortization
and a final payment at maturity. The Credit Agreement bears interest at variable
rates, which are based upon (a) either (i) the bank's base rate or (ii) LIBOR
plus (b) a margin which varies according to the ratio of the Company's funded
debt to EBITDA, each as defined in the Credit Agreement. The bank's base rate at
December 31, 1997 was 8.5%. A commitment fee is payable quarterly at rates
ranging from 0.125 percent to 0.5 percent of the unused amounts for such
quarter. The Credit Agreement is collateralized by substantially all of the
Company's assets and contains affirmative and negative covenants that require
the Company to maintain certain financial ratios, limit the creation or
existence of liens and set certain restrictions on acquisitions, mergers, sale
of assets and restrict the payment of dividends.

The Company retired approximately $23.9 million of long-term debt in 1997 with
proceeds of the initial public offering. The retirement of debt consisted of
$10.4 million of senior subordinated notes, $9.1 million of Bank Credit Facility
debt and $4.4 million of promissory notes in connection with certain
acquisitions. In connection with the repayment of $9.5 million in 12% Senior
Subordinated Debt in September 1997, the Company recognized a $3.2 million
extraordinary loss associated with the early retirement of such debt.

At December 31, 1997, approximately $268,000 (net of accumulated amortization of
$9,000) of debt issuance costs, had been capitalized in connection with the
issuance of the new Credit Agreement. All costs associated with the Bank Credit
Facility and the Senior Subordinated Notes were included with the extraordinary
loss.

The Company has issued various subordinated promissory notes payable in
connection with certain acquisitions ("Seller Notes") (Note 4). Through
September 1997, interest on the Seller Notes ranged from 6.36 percent to 10.0
percent. As of December 31, 1997, one noninterest bearing Seller Note issued in
December 1997 remained outstanding, which was paid in January 1998 from proceeds
borrowed under the Credit Agreement.

The aggregate maturities of long-term debt for each of the next five years
subsequent to December 31, 1997 were as follows (in thousands):

   1998                                                      $     2,598

6. PREFERRED STOCK:

The Company issued 119,231 shares of Series B Convertible Preferred Stock (the
"Series B Stock") in connection with the acquisition of SW Dental (Note 4).
The number of shares issued were equivalent to $1,550,000 divided by the initial
public offering price of the Company's common stock of $13.00 per share. The
Series B Stock will be convertible at the holder's option, for a thirty-day
period beginning one year after its issuance (the "Conversion Period"), into an
equivalent number of shares of the Company's common stock. Alternatively, during
the Conversion Period, the holder may require the Company to redeem the Series B
Stock in quarterly increments of $114,000. The Company may call the Series B
Stock at any time following the Conversion Period.

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


The Company has entered into operating leases for various types of office
equipment and for its building facilities. Certain building facility leases
include rent escalation clauses. Most leases contain purchase and renewal
options at fair market rental values.

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.

7.  COMMITMENT AND CONTINGENCIES, continued:

LITIGATION, CONTINUED

In July and August 1997, a dentist from whom the Company acquired Horizon Dental
Centers, in August 1996, contacted the Company asserting that the Company
misrepresented the value of the Common Stock issued to him as a part of the
consideration for the acquisition and demanded the issuance of approximately
200,000 shares of Common Stock as additional consideration for the transaction.
The Company believes that these asserted claims are without merit and has denied
the demand for the issuance of additional shares of Common Stock. In the event,
that litigation is initiated against the Company, the Company intends to defend
itself vigorously. In the opinion of management, resolution of these claims
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 an employment agreement with
each full time dentist, orthodontist and other dental specialist it employs.
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 $3,000,000 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.

Year 2000

The year 2000 issue is the result of computer programs using two digits to
define the applicable year rather than four. Any programs that have time
sensitive software may recognize a date using "00" as the year 1900 rather than
the year 2000. A computer system that is not year 2000 compliant would not be
able to correctly process certain data, or, in extreme situations, system
failure could result.

As part of the Company's continuing program to update its information systems in
anticipation of future growth, the Company has recently completed the purchase
and installation of year 2000 compliant software for its operations. The Company
is also currently evaluating software systems for its operations and expects to
have year 2000 compliant software in place by the end of 1998. Accordingly, the
Company does not expect the year 2000 issue to have a material effect on its
financial position, results of operations or cash flows.

At December 31, 1997, the Company had net operating loss carryforwards available
to reduce future taxable income of approximately $6.0 million, expiring in 2017.
The Company has not recorded a valuation allowance for the potential inability
to realize its net deferred tax assets because, after consideration of the
affiliated dental practices' historical operating results and the Company's
planned operations, management believes that it is more likely than not that the
Company will realize those assets.

 9. Stock Option Plans:

The Company grants stock options under the Castle Dental Centers, Inc. Omnibus
Stock and Incentive Plan, a stock-based incentive compensation plan (the
"Employees' Plan"), and the Non-employee Directors' Stock Option Plan (the
"Directors' Plan," together the "Plans") which are described below. The Company
applies APB Opinion 25 and related Interpretations in accounting for the Plan.
In 1995, the FASB issued FASB Statement No. 123 "Accounting for Stock-Based
Compensation" ("SFAS 123") which, if fully adopted by the Company, would change
the methods the Company applies in recognizing the cost of the Plan. Adoption of
the cost recognition provisions of SFAS 123 is optional and the Company has
decided not to elect these provisions of SFAS 123. However, pro forma
disclosures as if the Company adopted the cost recognition provisions of SFAS
123 in 1995 are required by SFAS 123 and are presented below.

Under the Employees' Plan, the Company is authorized to issue 750,000 shares of
Common Stock pursuant to "Awards" granted to officers and key employees in the
form of stock options and restricted stock. Under the Directors' Plan, the
Company is authorized to issue 150,000 shares of Common Stock to non-employee
directors of the Company. There are 505,000 and 125,000 options granted under
the Employees' Plan and the Directors' Plan, respectively, at December 31, 1997.
The Compensation Committee administers the Plans.

The fair value of each stock option granted by the Company is estimated on the
date of grant using the minimum value method for 1996 and Black-Scholes option
pricing model for 1997 with the following weighted-average assumptions: dividend
yield of 0% for both years; expected volatility of 0% for 1996 and 45% for 1997;
risk-free interest rates are 6% for 1996 and 1997; and the expected lives of the
options average six years.

9. Stock Option Plans, CONTINUED:

Had the compensation cost for the Company's stock-based compensation plans been
determined consistent with SFAS 123, the Company's net loss and basic and
diluted net loss per common share for 1997 would approximate $2,920,000 or $0.71
per share. The pro forma effect for 1996 is immaterial.

The effects of applying SFAS 123 in this pro forma disclosure are not indicative
of future amounts. SFAS 123 does not apply to awards prior to 1995.

10. EARNINGS PER SHARE:

A reconciliation of the numerators and denominators of the basic and diluted
per-share computations for net income follows:

(1)     The effect of the preferred stock acretion is excluded from earnings per
        share. The preferred stock was converted to common stock at a nominal
        value and those common shares were included in the calculation of Basic
        shares outstanding for all periods.

Options to purchase an aggregate 125,000 shares of common stock at exercise
prices of $13.00 per share were excluded from the calculation of diluted
earnings per share for 1997 because their effect would have been antidilutive.
The options, which expire in 2007, were still outstanding at December 31, 1997.

11. DEFINED CONTRIBUTION PLANS:

In August 1996, the Company adopted a defined contribution plan qualified under
Section 401(k) of the Internal Revenue Code of 1986 (the "401(k) Plan"). All
permanent employees of the Company, except those of the Tennessee subsidiary,
are eligible to participate in the 401(k) Plan upon the completion of six months
of service. The Company maintains a separate defined contribution 401(k) plan
for all permanent employees of the Company's Tennessee subsidiary ("Tennessee
401(k) Plan"). Employees are eligible to participate in the Tennessee 401(k)
Plan upon the completion of four months of service. The Company may match
contributions made by participants under both Plans each year in an amount
determined by the Company on a year-to-year basis.

The Company did not make any contributions to either Plan in 1996 or 1997.

13. CREDIT RISK AND FAIR VALUE OF FINANCIAL INSTRUMENTS:

CREDIT RISK

The Company grants customers credit in the normal course of business. The
Company does not require collateral on the extension of credit. Procedures are
in effect to monitor the creditworthiness of customers and appropriate
allowances are made to reduce accounts to their net realizable values.

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.

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 the revolving line of credit approximate fair values due to the
short-term maturities of these instruments. The carrying amounts of the
Company's long-term borrowings and preferred stock as of December 31, 1996 and
1997, respectively, approximate their fair value based on the Company's current
incremental borrowing rates for similar type of borrowing arrangements.

The carrying amounts of the Company's Series B Stock and warrants approximate
their fair value based on the Company's financial condition at December 31,
1997.

14.     RELATED PARTY TRANSACTIONS:

The Company maintains a management services agreement with one of the Company's
Texas affiliated dental practices (organized as professional corporations)
pursuant to which the shareholder receives an annual salary of $100,000 to take
actions necessary to maintain the dental license for the affiliated dental
practice in the state of Texas, for as long as he holds such license and is the
sole shareholder of the practice. Such compensation arrangement was negotiated
between the shareholder and previously unaffiliated investors in the Company. In
addition, the shareholder receives $131,500 per quarter pursuant to the terms of
the Deferred Compensation Agreement (Note 2).

During 1995, the Company entered into a lease agreement with Goforth, Inc., a
company owned by the Company's chairman and chief executive officer (the
"Affiliate"). The Company has agreed to pay the Affiliate a minimum guaranteed
rental of $12,000 per month through January 2001 and $13,200 per month from
January 2001 through January 2006 for rental of a dental center. The Company has
also agreed to pay additional rent of approximately $1,600 per month for
insurance, taxes and common area maintenance. The Company paid $188,000,

        (1)Earnings per share are computed independently for each of the
           quarters presented. Therefore, the sum of the quarterly earnings per
           share does not equal the total computed for the year due to stock
           transactions which occurred.

The Company has restated its previously issued financial statements on Form 10-Q
for the third quarter of 1997. The restatement is attributable to a tax benefit
for the extraordinary loss with the early extinguishment of debt. The impact of
this adjustment is to decrease the extraordinary loss and net loss by $490,000
for the third quarter of 1997.

16.     SUBSEQUENT EVENTS:

 * Incorporated herein by reference to the Company's Registration Statement on
Form S-1 (registration number 333-1335)
                                      II-8

                                                                    EXHIBIT 4.15

                         REGISTRATION RIGHTS AGREEMENT


      REGISTRATION RIGHTS AGREEMENT, dated as of December 31, 1997 (the
"Agreement"), by and between CASTLE DENTAL CENTERS, INC., a Delaware corporation
(the "Company"), and STEVE W. LEBO, D.D.S. (the "Holder").

      1. INTRODUCTIONContemporaneously with the execution and delivery of this
Agreement, the Holder acquired an aggregate of 165,000 shares of the Company's
Common Stock $.001 par value per share ("Common Stock") on December 8, 1997,
subject to adjustment for stock splits, stock dividends, reclassification and
similar events. The Company has agreed to grant to the Holder and hereby grants
under this Agreement certain registration rights with respect to the shares of
Common Stock held by the Holder. Prior to the date hereof, the Company entered
into a Registration Rights Agreement dated as of December 18, 1995, as amended
and restated on June 16, 1997, with purchasers of the Company's Series A and
Series C 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), 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
reasonable best efforts to effect the registration under the Securities Act of
all Holder Securities which the Company has been so 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
<PAGE>
obligation to pay the Registration Expenses in connection therewith or to
include any Holder Securities in subsequent registrations), 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 reasonable 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
      reasonable best efforts to cause such registration statement to become
      effective, PROVIDED that the Company may discontinue

                                    -2-
<PAGE>
      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;

                        (v) use its reasonable 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:

                                    -3-
<PAGE>
                              (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;

                        (viii)otherwise use its reasonable 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

                                    -4-
<PAGE>
                        (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 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, and each
other Person, if any, who controls such seller within the meaning of the
Securities Act, against any losses, claims, damages 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

                                    -5-
<PAGE>
otherwise, insofar as such losses, claims, damages 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 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 (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

                                    -6-
<PAGE>
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 of the holders of Holder Securities to include such
Holder Securities in any registration of its securities contemplated by this
Section 2 or the marketability of such Holder Securities under any such
registration.

benefit of and be enforceable by the parties hereto and their respective
successors and assigns. In addition, and whether or not any express assignment

      12. EXTENSION OF ADDITIONAL REGISTRATION RIGHTS. The Holders acknowledge

rights to other holders of its securities, and that such action by the Company
shall not constitute a breach of or a default under this Agreement. It is the
intent of the parties hereto that this Agreement be read consistently with the
Original Registration Rights Agreement, but in the event of a conflict
therewith, the provisions of the Original Registration Rights Agreement shall
control. If the Company shall hereafter grant any demand registration rights

rights granted under this Agreement, the Holder shall immediately be vested with
such more favorable rights.

      13. LOCK-UP AGREEMENT. If requested in writing by the underwriters for any
underwritten public offering of securities of the Company, the Holders shall

         in cash on January 2, 1998. The Cash Amount shall be evidenced by an

                  (b) A number of shares of Common Stock, $.001 par value, of
         Castle Dental Centers, Inc. ("Castle Dental" or "Parent"), equal to One

         his individual capacity.

                                       -6-
<PAGE>
         build-out and equipment pursuant to the Company's planned expansion
         into the new dental center in North Richland Hills, Texas ("EBITDA")
         for the period commencing January 1, 1998, and ending as of the close
         of business on December 31, 1998 (the "1998 Fiscal Year") exceeds
         $750,000 (the "Excess Amount"), Shareholder shall be entitled to
         receive, as an addition to the Purchase Price and not as compensation,
         an amount equal to the product determined by multiplying the Excess
         Amount by 4.25 (the "Earnout Amount"); provided, however, that in no
         event shall the Earnout Amount exceed $500,000. At the option of
         Purchaser, to be determined by Purchaser prior to the end of the 1998
         Fiscal Year, the Earnout Amount shall be payable in cash or by the
         delivery by Purchaser to Shareholder of a note in the form of Exhibit
         A-2 attached hereto (the "Note"). The Earnout Amount shall be due and
         payable to Shareholder on or before, but not later than, March 31,
         1999.

                  (b) EBITDA, the Excess Amount and the Earnout Amount for the
         1998 Fiscal Year shall be calculated by Purchaser's Chief Financial
         Officer or Treasurer (the "Purchaser's Accountant"). The operations of
         the Company, the books and records, and the accounting systems and
         procedures utilized in connection therewith, shall be maintained in a
         manner so as to enable EBITDA, the Excess Amount and the Earnout Amount
         for the 1998 Fiscal Year to be determined. Within forty-five (45)
         calendar days of the close of the 1998 Fiscal Year, Purchaser will
         prepare and deliver to Shareholder an income statement as of the close
         of the 1998 Fiscal Year (the "1998 Fiscal Year Income Statement")
         showing the computation of EBITDA for the 1998 Fiscal Year, computed in
         accordance with the provisions set forth herein. The 1998 Fiscal Year
         Income Statement will be prepared, and EBITDA as set forth on such
         income statement will be determined, in accordance with GAAP (to the
         extent applicable to such calculation) applied on a basis consistent
         with that theretofore used in, and in accordance with the same
         accounting principles theretofore applied on an historical basis in,
         the preparation of the Company's financial statements for the period
         prior to the Closing Date. The 1998 Fiscal Year Income Statement shall
         also set forth the calculations of the Excess Amount and the Earnout
         Amount computed in accordance with the provisions set forth herein.
         Within fifteen (15) calendar days following receipt of the 1998 Fiscal
         Year Income Statement, Shareholder shall notify Purchaser in writing as
         to whether Shareholder agrees with the calculations of EBITDA, the
         Excess Amount and the Earnout Amount as calculated by Purchaser's
         Accountant. In the event Shareholder does not agree with such
         calculations, or to the extent Shareholder does not agree with such
         calculations, the 1998 Fiscal Year Income Statement shall be reviewed
         by Coopers & Lybrand, L.L.P., or any successor entity thereto (the
         "Independent Accountants") who shall determine EBITDA, the Excess
         Amount and the Earnout Amount to the extent disputed by Shareholder. If
         the Shareholder does not provide the foregoing notice within said
         fifteen (15) day period or to the extent Shareholder does not disagree
         with any of the calculations made by the Purchaser's Accountant, such
         financial statements or calculations, as the case may be, shall be
         deemed accepted by the Shareholder. Such 1998 Fiscal Year Income
         Statement shall be reviewed by the Independent Accountants and shall

         Year.

                  (c) Within fifteen (15) calendar days after receipt by
         Purchaser and Shareholder of the 1998 Fiscal Year Income Statement
         pursuant to which the Earnout Amount is payable, such Earnout Amount
         shall be payable to Shareholder either in cash or by delivery of the
         Note.

         3.3 AGENCY RELATIONSHIP. In the event that, following the Closing Date,

described thereon which expire by their terms prior to the Closing and there
exists no default or event of default or event, occurrence, condition or act

time or the happening of any other event or condition, would

                                      -11-

presently subject to revocation or challenge except for those Permits which
expire by their terms prior to the Closing or which if revoked would not have a
Material Adverse Effect on the Company. Except as set forth on Schedule 4.13,

other instrumentality or agency, pending, or, to the knowledge of the Company
and the Shareholder, threatened, against or affecting the properties, rights or
goodwill of the Company, the Shareholder, or employees of the Company, and the
Company and the Shareholder do not know of any valid basis for any such action,
proceeding or investigation which, if determined adversely to the Company, would

Returns as filed are or will be accurate in all material respect except where
the failure to file any of the Returns in a timely fashion would not have a
Material Adverse Effect on the Company.

(the "Purchaser Indemnitees") harmless from and against any and all Damages
suffered by any Purchaser Indemnitee as a result of, caused by, arising out of,
or in any way relating to (a) any misrepresentation, breach of warranty, or
nonfulfillment of any agreement or covenant on the part of the Company or the
Shareholder under this Agreement or any misrepresentation in or omission from
any list, schedule, certificate, or other instrument furnished or to be
furnished to the Purchaser by the Company pursuant to the terms of this
Agreement or (b) any liability or obligation (other than those for which the
Company and the Shareholder are being indemnified by Purchaser hereunder) which
pertains to the ownership, operation or conduct of the Business arising from any
acts, omissions, events, conditions or circumstances occurring before the
Closing Date.

         11.3 DEMANDS. Each indemnified party hereunder agrees that promptly
upon 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 in accordance with the provisions

                                      -27-
<PAGE>
of this Agreement in sufficient time to permit the indemnifying party or its
counsel to defend against such matter and to make 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, only insofar as such knowing failure to notify the indemnifying party
has 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 using counsel
reasonably acceptable to the indemnified party; 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 and if
such notice is not so delivered, the indemnified party shall have the right to
contest, defend and settle such Claim at the expense of the indemnifying party
using counsel of its own choosing. 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 it assumes the defense of the Claim; 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 expense. 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 hereunder only to the
extent of the amount that the other party to the contested Claim had agreed
unconditionally to accept in payment or compromise as of the time the
indemnifying party made its request therefor to the indemnified party. The
indemnifying party shall not compromise or settle any Claim, in whole or in
part, or incur any costs or expenses or otherwise assume any contractual
obligation, or admit any liability, with respect to any Claim, without the prior
written consent of the indemnified party being first obtained and unless the
indemnified party is given an absolute and unqualified release. Further, the
indemnified party shall not compromise or settle any Claim, in whole or in part,
unless or until the indemnifying party has been given an absolute and
unconditional release of all liability and responsibility with respect to such
Claim.

         11.5 COOPERATION. If requested by the indemnifying party, the
indemnified party agrees to cooperate with the indemnifying party and its
counsel in contesting any Claim that the

                                      -28-
<PAGE>
indemnifying party elects to contest or, if appropriate, in making any
counterclaim against the person asserting the Claim, or any cross-complaint
against any person, and the indemnifying party will reimburse the indemnified
party for any expenses incurred by it in so cooperating. At no cost or expense
to the indemnified party, the indemnifying party shall cooperate with the
indemnified party and its counsel in contesting any Claim.

         11.6 RIGHT TO PARTICIPATE. The indemnified party agrees to afford the
indemnifying party and its counsel the opportunity to be present at, and to
participate in, conferences with all persons, including governmental
authorities, asserting any Claim against the indemnified party or conferences
with representatives of or counsel for such persons.

         11.7 PAYMENT OF DAMAGES. The indemnifying party shall pay to the
indemnified party in immediately available funds any amounts to which the
indemnified party may become entitled by reason of the provisions of this
Agreement, such payment to be made within five days after any such amounts are
finally determined either by mutual agreement of the parties hereto or pursuant
to the final unappealable judgment of a court of competent jurisdiction.

         11.8 RIGHT OF SETOFF. Purchaser shall have the right to set off any
amounts owed by the Company or Shareholder under this Article XI against any
Earnout Amount Purchaser may owe pursuant to Section 3.2.

         11.9 DISPUTE AS TO RIGHT OF INDEMNIFICATION. In the event the question
of the right of indemnification is submitted to a court of competent
jurisdiction, arbitration panel or other tribunal for determination, all
attorneys' fees and other costs and expenses in determining the question of the
right of an indemnified party to indemnification shall be awarded to the
prevailing party and against the party against whom such determination is
rendered.

         11.10 INDEMNIFICATION DEDUCTIBLE. No Claim shall be asserted by an
indemnified party pursuant to the provisions of this Article XI unless and until
the amount of such indemnified party's Damages in the aggregate exceed $30,000
(the "Deductible"). An indemnifying party shall be liable for Damages in excess
of the Deductible but limited to the Indemnification Cap (as defined below).

         11.11 INDEMNIFICATION CAP. The aggregate amount of Damages recoverable
under this Agreement or in respect hereof (the "Indemnification Cap") by each of
all of the Company Indemnitees and all of the Purchaser Indemnitees shall be
limited to an amount equal to the Cash Amount and the fair market value of the
Castle Dental Shares at the time the Damages are incurred. Shareholder shall
have the right to tender Castle Dental Shares in satisfaction of any Damages for
which he is responsible hereunder and receive credit therefore. Purchaser shall
have the right to have an independent appraiser who is reasonably acceptable to
Shareholder determine the fair market value of Shareholder's shares.

         11.12 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made by any party hereto to the other pursuant to the terms of
this Agreement shall survive the Closing, and continue in full force and effect
until the second anniversary of the Closing Date (the "Survival Date"). From and
after the Survival Date, no party hereto shall be under any liability whatsoever
pursuant to this Article XI with respect to any matter for which indemnification
may be sought except with respect to matters for which notice has been received
in accordance with the provisions of this Article XI or matters known but not
disclosed.

or conversion. Without in any way limiting the Borrower's obligation to confirm
in writing any telephonic notice, the Agent may act without liability upon the
basis of telephonic notice believed by the Agent in good faith to be from the
Borrower prior to receipt of written confirmation. In each such case, the
Borrower hereby waives the right to dispute the Agent's record of the terms of
such telephonic notice except in the case of gross negligence or willful
misconduct by the Agent.

        (d) CONTINUATION OPTIONS. Subject to the provisions made in this Section
2.02(d), the Borrower may elect to continue all or any part of any Eurodollar
Loan beyond the expiration of the then current Interest Period relating thereto
by giving advance notice as provided in Section 2.02(c) to the Agent (which
shall promptly notify the Lenders) of such election, specifying the amount of
such Loan to be continued and the Interest Period therefor. In the absence of
such a timely and proper election, the Borrower shall be deemed to have elected
to convert such Eurodollar Loan to a Base Rate Loan pursuant to Section 2.02(e).
All or any part of any Eurodollar Loan may be continued as provided herein,
provided that (i) any continuation of any such Loan shall be (as to each Loan as
continued for an applicable Interest Period) in amounts of at least $100,000 or
any whole multiple of $100,000 in excess thereof and (ii) no Default shall have
occurred and be continuing. If a Default shall have occurred and be continuing,
each Eurodollar Loan shall be converted to a Base Rate Loan on the last day of
the Interest Period applicable thereto.

        (e) CONVERSION OPTIONS. The Borrower may elect to convert all or any
part of any Eurodollar Loan on the last day of the then current Interest Period
relating thereto to a Base Rate Loan by giving advance notice to the Agent
(which shall promptly notify the Lenders) of such election. Subject to the
provisions made in this Section 2.02(e), the Borrower may elect to convert all
or any part of any Base Rate Loan at any time and from time to time to a
Eurodollar Loan by giving advance notice as provided in Section 2.02(c) to the
Agent (which shall promptly notify the Lenders) of such election. All or any
part of any outstanding Loan may be converted as provided herein, provided that
(i) any conversion of any Base Rate Loan into a Eurodollar Loan shall be (as to
each such Loan into which there is a conversion for an applicable Interest
Period) in amounts of at least $100,000 or any whole multiple of $100,000 in
excess thereof and (ii) no Default shall have occurred and be continuing. If a
Default shall have occurred and be continuing, no Base Rate Loan may be
converted into a Eurodollar Loan.

        (f) ADVANCES. Not later than 11:00 a.m. Houston time on the date
specified for each borrowing hereunder, each Lender shall make available the
amount of the Loans to be made by it on such date to the Agent, to an account
which the Agent shall specify, in immediately available funds,

                                           - 16 -
<PAGE>
for the account of the Borrower. The amounts so received by the Agent shall,
subject to the terms and conditions of this Agreement, be made available to the
Borrower by depositing the same, in immediately available funds, in an account
of the Borrower, designated by the Borrower and maintained at the Principal
Office.

        (g ) LETTERS OF CREDIT. The Borrower shall give the Issuing Bank (which
shall promptly notify the Lenders of such request and their Percentage Share of
such Letter of Credit) advance notice to be received by the Issuing Bank not
later than 11:00 a.m. Houston time not less than three (3) Business Days prior
thereto of each request for the issuance, and at least five (5) Business Days
prior to the date of the renewal, increase or extension, of a Letter of Credit
hereunder which request shall specify (i) the amount of such Letter of Credit,
(ii) the date (which shall be a Business Day) such Letter of Credit is to be
issued, increase, renewed or extended, (iii) the duration thereof, (iv) the name
and address of the beneficiary thereof, (v) the form of the Letter of Credit and
(vi) such other information as the Agent may reasonably request, all of which
shall be reasonably satisfactory to the Agent. Subject to the terms and
conditions of this Agreement, on the date specified for the issuance, increase,
renewal or extension of a Letter of Credit, the Agent shall issue, increase,
renew or extend such Letter of Credit to the beneficiary thereof.

        In conjunction with the issuance of each Letter of Credit, the Borrower,
shall execute a Letter of Credit Agreement. In the event of any conflict between
any provision of a Letter of Credit Agreement and this Agreement, the Borrower,
the Issuing Bank, the Agent and the Lenders hereby agree that the provisions of
this Agreement shall govern.

        The Issuing Bank will send to the Borrower and each Lender, immediately
upon issuance of any Letter of Credit, or an amendment thereto, a true and
complete copy of such Letter of Credit, or such amendment thereto.

        Section 2.03  CHANGES OF REVOLVING CREDIT COMMITMENTS.

        (a) The Aggregate Revolving Credit Commitments shall at all times be
equal to the lesser of (i) the Aggregate Maximum Revolving Credit Amounts after
adjustments resulting from reductions pursuant to Section 2.03(b) or (ii) the
Borrowing Base as determined from time to time.

        (b) The Borrower shall have the right to terminate or to reduce the
amount of the Aggregate Maximum Revolving Credit Amounts at any time, or from
time to time, upon not less than three (3) Business Days' prior notice to the
Agent (which shall promptly notify the Lenders) of each such termination or
reduction, which notice shall specify the effective date thereof and the amount
of any such reduction (which shall not be less than $100,000 or any whole
multiple of $100,000 in excess thereof) and shall be irrevocable and effective
only upon receipt by the Agent.

        (c) The Aggregate Maximum Revolving Credit Amounts once terminated or
reduced may not be reinstated.

        (d) The Agent, on a best efforts basis, will seek to find an additional
financial institution that will agree to become a Lender under the Credit
Agreement with a Revolving Credit Commitment of $5,000,000 and assume a
16.66666667% interest in the Term Loan. If such

                                           - 17 -
<PAGE>
additional Lender becomes a party to the Credit Agreement (which may only be
done prior to the Revolving Credit Termination Date), the Aggregate Maximum
Credit Amounts will increase from $25,000,000 to $30,000,000 and a revised Annex
I reflecting such change and any changes in Percentage Shares and Term Loan
amounts of each Lender will be distributed to all parties to the Credit
Agreement.

        Section 2.04  FEES.

        (a) COMMITMENT FEE. The Borrower shall pay to the Agent for the account
of each Lender a commitment fee based on the daily average unused amount of the
Aggregate Revolving Credit Commitments less the outstanding principal amount of
the Term Loans for the period from and including the Closing Date, up to, but
excluding the earlier of the date the Aggregate Revolving Credit Commitments are
terminated or the Revolving Credit Termination Date at a rate per annum equal to
applicable per annum percentage set forth at the appropriate intersection in the
table shown below, based on the ratio of Funded Debt to EBITDA as in effect from
time to time. Accrued commitment fees shall be payable quarterly in arrears on
each Quarterly Date and on the earlier of the date the Aggregate Revolving
Credit Commitments are terminated or the Revolving Credit Termination Date.

        FUNDED DEBT TO EBITDA                        COMMITMENT FEE PERCENTAGE

        Greater than or equal to 2.5                             .5%

        (b) LETTER OF CREDIT FEES. The Borrower agrees to pay the Agent, for the
account of each Lender, commissions for issuing the Letters of Credit on the
daily average outstanding of the maximum liability of the Issuing Bank existing
from time to time under such Letter of Credit (calculated separately for each
Letter of Credit) at the rate of 2% per annum, provided that each Letter of
Credit shall bear a minimum commission of $1,000.00. Each Letter of Credit shall
be deemed to be outstanding up to the full face amount (plus any increases) of
the Letter of Credit until the Issuing Bank has received the canceled Letter of
Credit or a written cancellation of the Letter of Credit from the beneficiary of
such Letter of Credit in form and substance acceptable to the Issuing Bank, or
for any reductions in the amount of the Letter of Credit (other than from a
drawing), written notification from the beneficiary of such Letter of Credit.
Such commissions are payable quarterly in arrears on each Quarterly Date and
upon cancellation or expiration of each such Letter of Credit.

        (c) FEE LETTER. The Borrower shall pay to the Agent for its account such
other fees as are set forth in the fee letter between Borrower and Agent, dated
of even date herewith, on the dates specified therein to the extent not paid
prior to the Closing Date.

        Section 2.05 SEVERAL OBLIGATIONS. The failure of any Lender to make any
Loan to be made by it or to provide funds for disbursements or reimbursements
under Letters of Credit on the date

                                           - 18 -
<PAGE>
specified therefor shall not relieve any other Lender of its obligation to make
its Loan or provide funds on such date, but no Lender shall be responsible for
the failure of any other Lender to make a Loan to be made by such other Lender
or to provide funds to be provided by such other Lender.

        Section 2.06 NOTES. The Revolving Credit Loans made by each Lender shall
be evidenced by a single promissory note of the Borrower in substantially the
form of EXHIBIT A-1, dated (i) the Closing Date or (ii) the effective date of an
Assignment pursuant to Section 12.06(b), payable to the order of such Lender in
a principal amount equal to its Maximum Revolving Credit Amount as originally in
effect and otherwise duly completed and such substitute Notes as required by
Section 12.06(b). The Term Loans made by each Lender shall be evidenced by a
single promissory note of the Borrower in substantially the form of EXHIBIT A-2,
dated as of (i) the Closing Date or (ii) the effective date of an Assignment
pursuant to Section 12.06(b), payable to the order of such Lender and otherwise
duly completed and such substitute Notes as required by Section 12.06(b). The
date, amount, Type, interest rate and Interest Period of each Loan made by each
Lender, and all payments made on account of the principal thereof, shall be
recorded by such Lender on its books for its Notes, and, prior to any transfer
may be endorsed by such Lender on the schedule attached to such Notes or any
continuation thereof or on any separate record maintained by such Lender.
Failure to make any such notation or to attach a schedule shall not affect any
Lender's or the Borrower's rights or obligations in respect of such Loans or
affect the validity of such transfer by any Lender of its Notes.

        Section 2.07  PREPAYMENTS.

        (a) VOLUNTARY PREPAYMENTS. The Borrower may prepay the Base Rate Loans
upon not less than one (1) Business Day's prior notice to the Agent (which shall
promptly notify the Lenders), which notice shall specify the prepayment date
(which shall be a Business Day) and the amount of the prepayment (which shall be
at least $10,000 or the remaining aggregate principal balance outstanding on the
Notes) and shall be irrevocable and effective only upon receipt by the Agent,
provided that interest on the principal prepaid, accrued to the prepayment date,
shall be paid on the prepayment date. The Borrower may prepay Eurodollar Loans
on the same conditions as for Base Rate Loans (except that prior notice to the
Agent shall be not less than three (3) Business Days for Eurodollar Loans) and
in addition such prepayments of Eurodollar Loans shall be subject to the terms
of Section 5.05 and shall be in an amount equal to all of the Eurodollar Loans
for the Interest Period prepaid.

        Notwithstanding the foregoing, if the Borrower should prepay the
Revolving Credit Loans in their entirety, Borrower shall pay to the Agent, for
the benefit of the Lenders, a prepayment fee calculated as follows:

               (i)    if such prepayment occurs on or before the first
                      anniversary of the Closing Date, 1.5% of the Aggregate
                      Revolving Credit Commitment as of the Closing Date; or

               (ii)   if such prepayment occurs after the first anniversary of
                      the Closing Date, but on or before the second anniversary
                      of the Closing Date, 1.0% of the Aggregate Revolving
                      Credit Commitment as of the Closing Date.

                                           - 19 -
<PAGE>
        (b)    MANDATORY PREPAYMENTS.

               (i) If, after giving effect to any termination or reduction of
        the Aggregate Maximum Revolving Credit Amounts pursuant to Section
        2.03(b), the outstanding aggregate principal amount of the Revolving
        Credit Loans plus the LC Exposure exceeds the Aggregate Maximum
        Revolving Credit Amounts, the Borrower shall (A) prepay the Revolving
        Credit Loans on the date of such termination or reduction in an
        aggregate principal amount equal to the excess, together with interest
        on the principal amount paid accrued to the date of such prepayment and
        (B) if any excess remains after prepaying all of the Revolving Credit
        Loans because of LC Exposure, pay to the Agent on behalf of the Lenders
        an amount equal to the excess to be held as cash collateral as provided
        in Section 2.09(b) hereof.

               (ii) Upon any redetermination of the amount of the Borrowing
        Base, if the redetermined Borrowing Base is less than the aggregate
        outstanding principal amount of the Revolving Credit Loans plus the LC
        Exposure, then the Borrower shall within thirty (30) days of receipt of
        written notice thereof (A) prepay the Revolving Credit Loans in an
        aggregate principal amount equal to such excess, together with interest
        on the principal amount paid accrued to the date of such prepayment and
        (B) if a Borrowing Base deficiency remains after prepaying all of the
        Revolving Credit Loans because of LC Exposure, the Borrower shall pay to
        the Agent on behalf of the Lenders an amount equal to such Borrowing
        Base deficiency to be held as cash collateral as provided in Section
        2.09(b).

               (iii) If the Borrower raises any cash proceeds by the offering of
        equity, 50% of the net cash proceeds obtained from such equity offering
        shall be used to prepay the outstanding principal on the Loans, applied
        in accordance with Section 2.07(c) to either the Term Loans and/or the
        Revolving Credit Loans as the Borrower shall elect.

        (c) GENERALLY. Any prepayments on the Revolving Credit Loans made during
the Revolving Credit Period may be reborrowed pursuant to Section 2.01(a). Any
prepayments made on the Revolving Credit Loans during the Term Loan Period shall
be applied to installments of the Revolving Credit Notes in the inverse order of
maturity. Any prepayments on the Term Loans may not be reborrowed and shall be
applied to installments on the Term Notes in the inverse order of maturity.
Prepayments of Eurodollar Loans required by Section 2.07(b) shall be subject to
the terms of Section 5.05 and shall be in an amount equal to all of the
Eurodollar Loans for the Interest Period prepaid.

        Section 2.08 ASSUMPTION OF RISKS. The Borrower assumes all risks of the
acts or omissions of any beneficiary of any Letter of Credit or any transferee
thereof with respect to its use of such Letter of Credit or the proceeds
thereof. Neither the Issuing Bank (except in the case of willful misconduct or
gross negligence on the part of the Issuing Bank or any of its employees), its
correspondents nor any Lender shall be responsible for the validity, sufficiency
or genuineness of certificates or other documents or any endorsements thereon,
even if such certificates or other documents should in fact prove to be invalid,
insufficient, fraudulent or forged; for errors, omissions, interruptions or
delays in transmissions or delivery of any messages by mail, telex, or
otherwise,

                                           - 20 -
<PAGE>
whether or not they be in code; for errors in translation or for errors in
interpretation of technical terms; the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign any Letter of
Credit or the rights or benefits thereunder or proceeds thereof, in whole or in
part, which may prove to be invalid or ineffective for any reason; the failure
of any beneficiary or any transferee of any Letter of Credit to comply fully
with conditions required in order to draw upon any Letter of Credit; or for any
other consequences arising from causes beyond the Issuing Bank's control or the
control of the Issuing Bank's correspondents. In addition, neither the Issuing
Bank, the Agent nor any Lender shall be responsible for any error, neglect, or
default of any of the Issuing Bank's correspondents, except as a result of the
Issuing Bank's, the Agent's or any Lender's wilful misconduct or gross
negligence; and none of the above shall affect, impair or prevent the vesting of
any of the Issuing Bank's, the Agent's or any Lender's rights or powers
hereunder, or under the Letter of Credit Agreements, all of which rights shall
be cumulative. The Issuing Bank and its correspondents may accept certificates
or other documents that appear on their face to be in order, without
responsibility for further investigation of any matter contained therein
regardless of any notice or information to the contrary. In furtherance and not
in limitation of the foregoing provisions, the Borrower agrees that any action,
inaction or omission taken or not taken by the Issuing Bank or by any
correspondent for the Issuing Bank in good faith in connection with any Letter
of Credit, or any related drafts, certificates, documents or instruments, shall
be binding on the Borrower and shall not put the Issuing Bank or its
correspondents under any resulting liability to the Borrower, except as a result
of the Issuing Bank's, the Agent's or any Lender's wilful misconduct or gross
negligence.

        Section 2.09 OBLIGATION TO REIMBURSE AND TO PREPAY.

        (a) If a disbursement by the Issuing Bank is made under any Letter of
Credit, except as otherwise provided in Subsection 2.09(d) below, the Borrower
shall pay to the Agent within two (2) Business Days after notice of any such
disbursement is received by the Borrower, the amount of each such disbursement
made by the Issuing Bank under the Letter of Credit (if such payment is not
sooner effected as may be required under this Section 2.10 or under other
provisions of the Letter of Credit), together with interest on the amount
disbursed from and including the date of disbursement until payment in full of
such disbursed amount at a varying rate per annum equal to (i) the then
applicable interest rate for Base Rate Loans through the second Business Day
after notice of such disbursement is received by the Borrower and (ii)
thereafter, the Post-Default Rate for Base Rate Loans (but in no event to exceed
the Highest Lawful Rate) for the period from and including the third Business
Day following the date of such disbursement to and including the date of
repayment in full of such disbursed amount. The obligations of the Borrower
under this Agreement with respect to each Letter of Credit shall be absolute,
unconditional and irrevocable and shall be paid or performed strictly in
accordance with the terms of this Agreement under all circumstances whatsoever,
including, without limitation, but only to the fullest extent permitted by
applicable law, the following circumstances: (i) any lack of validity or
enforceability of this Agreement, any Letter of Credit or any of the Security
Instruments; (ii) any amendment or waiver of (including any default), or any
consent to departure from this Agreement (except to the extent permitted by any
amendment or waiver), any Letter of Credit or any of the Security Instruments;
(iii) the existence of any claim, set-off, defense or other rights which the
Borrower may have at any time against the beneficiary of any Letter of Credit or
any transferee of any Letter of Credit (or any Persons for whom

                                           - 21 -

<PAGE>
any such beneficiary or any such transferee may be acting), the Issuing Bank,
the Agent, any Lender or any other Person, whether in connection with this
Agreement, any Letter of Credit, the Security Instruments, the transactions
contemplated hereby or any unrelated transaction; (iv) any statement,
certificate, draft, notice or any other document presented under any Letter of
Credit proves to have been forged, fraudulent, insufficient or invalid in any
respect or any statement therein proves to have been untrue or inaccurate in any
respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit
against presentation of a draft or certificate which appears on its face to
comply, but does not comply, with the terms of such Letter of Credit; and (vi)
any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing.

Notwithstanding anything in this Agreement to the contrary, the Borrower will
not be liable for payment or performance that results from the gross negligence
or willful misconduct of the Issuing Bank, except where the Borrower or any
Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any
payment made by the Issuing Bank in connection with such gross negligence or
willful misconduct.

        (b) In the event of the occurrence of any Event of Default, a payment or
prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether by
acceleration or otherwise, an amount equal to the LC Exposure (or the excess in
the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by
the Borrower to the Issuing Bank, the Agent and the Lenders as of the date of
any such occurrence; and the Borrower's obligation to pay such amount shall be
absolute and unconditional, without regard to whether any beneficiary of any
such Letter of Credit has attempted to draw down all or a portion of such amount
under the terms of a Letter of Credit, and, to the fullest extent permitted by
applicable law, shall not be subject to any defense or be affected by a right of
set-off, counterclaim or recoupment which the Borrower may now or hereafter have
against any such beneficiary, the Issuing Bank, the Agent, the Lenders or any
other Person for any reason whatsoever. Such payments shall be held by the Agent
on behalf of the Lenders as cash collateral securing the LC Exposure in an
account or accounts at the Principal Office; and the Borrower hereby grants to
and by its deposit with the Agent grants to the Agent a security interest in
such cash collateral. In the event of any such payment by the Borrower of
amounts contingently owing under outstanding Letters of Credit and in the event
that thereafter drafts or other demands for payment complying with the terms of
such Letters of Credit are not made prior to the respective expiration dates
thereof, the Agent agrees, if no Event of Default has occurred and is continuing
or if no other amounts are outstanding under this Agreement, the Notes or the
Security Instruments, to remit to the Borrower amounts for which the contingent
obligations evidenced by the Letters of Credit have ceased.

        (c) Each Lender severally and unconditionally agrees that it shall
promptly reimburse the Issuing Bank an amount equal to such Lender's Percentage
Share of any disbursement made by the Issuing Bank under any Letter of Credit
that is not reimbursed according to this Section 2.10.

        (d) Notwithstanding anything to the contrary contained herein, if no
Event of Default has occurred and is continuing and subject to availability
under the Aggregate Revolving Credit Commitments (after reduction for LC
Exposure), to the extent the Borrower has not reimbursed the Issuing Bank for
any drawn upon Letter of Credit within two (2) Business Days after notice of
such

                                           - 22 -
<PAGE>
disbursement has been received by the Borrower, the amount of such Letter of
Credit reimbursement obligation shall automatically be funded by the Lenders as
a Revolving Credit Loan hereunder and used by the Lenders to pay such Letter of
Credit reimbursement obligation. If an Event of Default has occurred and is
continuing, or if the funding of such Letter of Credit reimbursement obligation
as a Revolving Credit Loan would cause the aggregate amount of all Revolving
Credit Loans outstanding to exceed the Aggregate Revolving Credit Commitments
(after reduction for LC Exposure), such Letter of Credit reimbursement
obligation shall not be funded as a Revolving Credit Loan, but instead shall
accrue interest as provided in Section 2.10(a).

        Section 2.10 LENDING OFFICES. The Loans of each Type made by each Lender
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

                                   ARTICLE III

annum:

               (i) if such a Loan is a Base Rate Loan, the Base Rate (as in
        effect from time to time) plus the Applicable Margin, but in no event to
        exceed the Highest Lawful Rate; and

                                           - 23 -

        (b) POST-DEFAULT RATE. Notwithstanding the foregoing, the Borrower will
pay to the Agent, for the account of each Lender interest at the applicable
Post-Default Rate on any principal of any Loan made by such Lender, and (to the
fullest extent permitted by law) on any other amount payable by the Borrower
hereunder, under any Loan Document or under any Note held by such Lender to or

interest rate provided for herein or any change therein, the Agent shall notify
the Lenders to which such interest is payable and the Borrower thereof. Each
determination by the Agent of an interest rate or fee hereunder shall, except in
cases of manifest error, be final, conclusive and binding on the parties.

                                   ARTICLE IV

                PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

        Section 4.01 PAYMENTS. Except to the extent otherwise provided herein,
all payments of principal, interest and other amounts to be made by the Borrower
under this Agreement, the Letter of Credit Agreements, and the Notes shall be
made in Dollars, in immediately available funds, to the Agent at such account as
the Agent shall specify by notice to the Borrower from time to time, not later
than 11:00 a.m. Houston time on the date on which such payments shall become due
(each such payment made after such time on such due date to be deemed to have
been made on the next succeeding Business Day). Such payments shall be made
without (to the fullest extent permitted by applicable law) defense, set-off or
counterclaim. Each payment received by the Agent under this Agreement or any
Note for account of a Lender shall be paid promptly to such Lender in
immediately available funds. Except as otherwise provided in the definition of
"Interest Period", if the due date of any payment under this Agreement or any
Note would otherwise fall on a day which is not a Business Day such date shall
be extended to the next succeeding Business Day and interest shall be payable
for any principal so extended for the period of such extension. At the time of
each payment to the Agent of any principal of or interest on any borrowing, the
Borrower shall notify the Agent of the Loans to which such payment shall apply.
In the absence of such notice the Agent may

                                           - 24 -
<PAGE>
specify the Loans to which such payment shall apply, but to the extent possible
such payment or prepayment will be applied first to the Loans comprised of Base
Rate Loans.

        Section 4.02 PRO RATA TREATMENT. Except to the extent otherwise provided
herein each Lender agrees that: (i) each borrowing from the Lenders under
Section 2.01 and each continuation and conversion under Section 2.02 shall be
made from the Lenders pro rata in accordance with their Percentage Share, each
payment of commitment fee or other fees under Section 2.04(a) and Section
2.04(b) shall be made for account of the Lenders pro rata in accordance with
their Percentage Share, and each termination or reduction of the amount of the
Aggregate Maximum Revolving Credit Amounts under Section 2.03(b) shall be
applied to the Revolving Credit Commitment of each Lender, pro rata according to
the amounts of its respective Revolving Credit Commitment; (ii) each payment of
principal of Loans by the Borrower shall be made for account of the Lenders pro
rata in accordance with the respective unpaid principal amount of the Loans held
by the Lenders; (iii) each payment of interest on Loans by the Borrower shall be
made for account of the Lenders pro rata in accordance with the amounts of
interest due and payable to the respective Lenders; and (iv) each reimbursement
by the Borrower of disbursements under Letters of Credit shall be made for
account of the Issuing Bank or, if funded by the Lenders, pro rata for the
account of the Lenders, in accordance with the amounts of reimbursement
obligations due and payable to each respective Lender.

        Section 4.03 COMPUTATIONS. Interest on Eurodollar Loans shall be
computed on the basis of a year of 360 days and actual days elapsed (including
the first day but excluding the last day) occurring in the period for which such
interest is payable, unless such calculation would exceed the Highest Lawful
Rate, in which case interest shall be calculated on the per annum basis of a
year of 365 or 366 days, as the case may be. Interest on Base Rate Loans and
fees shall be computed on the basis of a year of 365 or 366 days, as the case
may be, and actual days elapsed (including the first day but excluding the last
day) occurring in the period for which such interest is payable.

        Section 4.04 NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Agent shall
have been notified by a Lender or the Borrower prior to the date on which such
notifying party is scheduled to make payment to the Agent (in the case of a
Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be
made by it hereunder or (in the case of the Borrower) a payment to the Agent for
account of one or more of the Lenders hereunder (such payment being herein
called the "REQUIRED PAYMENT"), which notice shall be effective upon receipt,
that it does not intend to make the Required Payment to the Agent, the Agent may
assume that the Required Payment has been made and may, in reliance upon such
assumption (but shall not be required to), make the amount thereof available to
the intended recipient(s) on such date and, if such Lender or the Borrower (as
the case may be) has not in fact made the Required Payment to the Agent, the
recipient(s) of such payment shall, on demand, repay to the Agent the amount so
made available together with interest thereon in respect of each day during the
period commencing on the date such amount was so made available by the Agent
until, but excluding, the date the Agent recovers such amount at a rate per
annum which, for any Lender as recipient, will be equal to the Federal Funds
Rate, and for the Borrower as recipient, will be equal to the Base Rate plus the
Applicable Margin.

        Section 4.05  SET-OFF, SHARING OF PAYMENTS, ETC.

        (a) Upon the occurrence and during the continuance of an Event of
Default, the Borrower agrees that, in addition to (and without limitation of)
any right of set-off, bankers' lien or counterclaim a Lender may otherwise have,
each Lender shall have the right and be entitled (after consultation with the
Agent), at its option, to offset balances held by it or by any of its Affiliates
for account of the Borrower or any Subsidiary at any of its offices, in Dollars
or in any other currency, against any principal of or interest on any of such
Lender's Loans, or any other amount payable to such Lender hereunder, which is
not paid when due (regardless of whether such balances are then due to the
Borrower), in which case it shall promptly notify the Borrower and the Agent
thereof, provided that such Lender's failure to give such notice shall not
affect the validity thereof.

        (b) If any Lender shall obtain payment of any principal of or interest
on any Loan made by it to the Borrower under this Agreement (or reimbursement as
to any Letter of Credit) through the exercise of any right of set-off, banker's
lien or counterclaim or similar right or otherwise, and, as a result of such
payment, such Lender shall have received a greater percentage of the principal
or interest (or reimbursement) then due hereunder by the Borrower to such Lender
than the percentage received by any other Lenders, it shall promptly (i) notify
the Agent and each other Lender thereof and (ii) purchase from such other
Lenders participations in (or, if and to the extent specified by such Lender,
direct interests in) the Loans (or participations in Letters of Credit) made by
such other Lenders (or in interest due thereon, as the case may be) in such
amounts, and make such other adjustments from time to time as shall be
equitable, to the end that all the Lenders shall share the benefit of such
excess payment (net of any expenses which may be incurred by such Lender in
obtaining or preserving such excess payment) pro rata in accordance with the
unpaid principal and/or interest on the Loans held by each of the Lenders (or
reimbursements of Letters of Credit). To such end all the Lenders shall make
appropriate adjustments among themselves (by the resale of participations sold
or otherwise) if such payment is rescinded or must otherwise be restored. The
Borrower agrees that any Lender so purchasing a participation (or direct
interest) in the Loans made by other Lenders (or in interest due thereon, as the
case may be) may exercise all rights of set-off, banker's lien, counterclaim or
similar rights with respect to such participation as fully as if such Lender
were a direct holder of Loans (or Letters of Credit) in the amount of such
participation. Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of the Borrower. If under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.05 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.05 to share the benefits
of any recovery on such secured claim.

        Section 4.06  TAXES.

        (a) PAYMENTS FREE AND CLEAR. Any and all payments by the Borrower
hereunder shall be made, in accordance with Section 4.01, free and clear of and
without deduction for any and all present or future taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect thereto,
EXCLUDING, in the case of each Lender, the Issuing Bank and the Agent, taxes
imposed

                                           - 26 -
<PAGE>
on its income, and franchise or similar taxes imposed on it, by (i) any
jurisdiction (or political subdivision thereof) of which the Agent, the Issuing
Bank or such Lender, as the case may be, is a citizen or resident or in which
such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any
political subdivision thereof) in which the Agent, the Issuing Bank or such
Lender is organized, or (iii) any jurisdiction (or political subdivision
thereof) in which such Lender, the Issuing Bank or the Agent is presently doing
business which taxes are imposed solely as a result of doing business in such
jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges,
withholdings and liabilities being hereinafter referred to as "TAXES"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder to the Lenders, the Issuing Bank or the Agent (i) the sum
payable shall be increased by the amount necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 4.06) such Lender, the Issuing Bank or the Agent (as the case
may be) shall receive an amount equal to the sum it would have received had no
such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant taxing
authority or other Governmental Authority in accordance with applicable law and
provide the relevant Lender with a receipt thereof.

        (b) OTHER TAXES. In addition, to the fullest extent permitted by
applicable law, the Borrower agrees to pay any present or future stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, any
Assignment or any Security Instrument (hereinafter referred to as "OTHER
TAXES").

        (C) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK AND THE AGENT FOR
THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY
TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE
UNDER THIS SECTION 4.06) PAID BY SUCH LENDER, THE ISSUING BANK OR THE AGENT (ON
THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY
(INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT
THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY
ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED
AND SUCH LENDER'S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH
INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE DATE ANY LENDER,
THE ISSUING BANK OR THE AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND
THEREFOR. IF ANY LENDER, THE ISSUING BANK OR THE AGENT RECEIVES A REFUND OR
CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER, ISSUING
BANK OR THE AGENT HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY
NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS
OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS AFTER RECEIPT OF A REQUEST
BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED
APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO
SUCH REFUND OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST SO
REFUNDED OR CREDITED), PROVIDED THAT THE BORROWER, UPON THE REQUEST OF SUCH
LENDER, THE ISSUING BANK OR THE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT
(PLUS

                                           - 27 -
<PAGE>
PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER, THE ISSUING BANK OR THE
AGENT IN THE EVENT SUCH LENDER, THE ISSUING BANK OR THE AGENT IS REQUIRED TO
REPAY SUCH REFUND OR CREDIT.

        (d)    LENDER REPRESENTATIONS.

               (i) Each Lender represents that it is either (1) a banking
        association or corporation organized under the laws of the United States
        of America or any state thereof or (2) it is entitled to complete
        exemption from United States withholding tax imposed on or with respect
        to any payments, including fees, to be made to it pursuant to this
        Agreement (A) under an applicable provision of a tax convention to which
        the United States of America is a party or (B) because it is acting
        through a branch, agency or office in the United States of America and
        any payment to be received by it hereunder is effectively connected with
        a trade or business in the United States of America. Each Lender that is
        not a banking association or corporation organized under the laws of the
        United States of America or any state thereof agrees to provide to the
        Borrower and the Agent on the Closing Date, or on the date of its
        delivery of the Assignment pursuant to which it becomes a Lender, and at
        such other times as required by United States law or as the Borrower or
        the Agent shall reasonably request, two accurate and complete original
        signed copies of either (A) Internal Revenue Service Form 4224 (or
        successor form) certifying that all payments to be made to it hereunder
        will be effectively connected to a United States trade or business (the
        "FORM 4224 CERTIFICATION") or (B) Internal Revenue Service Form 1001 (or
        successor form) certifying that it is entitled to the benefit of a
        provision of a tax convention to which the United States of America is a
        party which completely exempts from United States withholding tax all
        payments to be made to it hereunder (the "FORM 1001 CERTIFICATION"). In
        addition, each Lender agrees that if it previously filed a Form 4224
        Certification, it will deliver to the Borrower and the Agent a new Form
        4224 Certification prior to the first payment date occurring in each of
        its subsequent taxable years; and if it previously filed a Form 1001
        Certification, it will deliver to the Borrower and the Agent a new
        certification prior to the first payment date falling in the third year
        following the previous filing of such certification. Each Lender also
        agrees to deliver to the Borrower and the Agent such other or
        supplemental forms as may at any time be required as a result of changes
        in applicable law or regulation in order to confirm or maintain in
        effect its entitlement to exemption from United States withholding tax
        on any payments hereunder, PROVIDED that the circumstances of such
        Lender at the relevant time and applicable laws permit it to do so. If a
        Lender determines, as a result of any change in either (i) a
        Governmental Requirement or (ii) its circumstances, that it is unable to
        submit any form or certificate that it is obligated to submit pursuant
        to this Section 4.06, or that it is required to withdraw or cancel any
        such form or certificate previously submitted, it shall promptly notify
        the Borrower and the Agent of such fact. If a Lender is organized under
        the laws of a jurisdiction outside the United States of America, unless
        the Borrower and the Agent have received a Form 1001 Certification or
        Form 4224 Certification satisfactory to them indicating that all
        payments to be made to such Lender hereunder are not subject to United
        States withholding tax, the Borrower shall withhold taxes from such
        payments at the applicable statutory rate. Each Lender agrees to
        indemnify and hold harmless the Borrower or Agent, as applicable, from
        any United States taxes, penalties,

                                           - 28 -
<PAGE>
        interest and other expenses, costs and losses incurred or payable by (i)
        the Agent as a result of such Lender's failure to submit any form or
        certificate that it is required to provide pursuant to this Section 4.06
        or (ii) the Borrower or the Agent as a result of their reliance on any
        such form or certificate which such Lender has provided to them pursuant
        to this Section 4.06.

               (ii) For any period with respect to which a Lender has failed to
        provide the Borrower with the form required pursuant to this Section
        4.06, if any, (other than if such failure is due to a change in a
        Governmental Requirement occurring subsequent to the date on which a
        form originally was required to be provided), such Lender shall not be
        entitled to indemnification under Section 4.06 with respect to taxes
        imposed by the United States which taxes would not have been imposed but
        for such failure to provide such forms; PROVIDED, HOWEVER, that if a
        Lender, which is otherwise exempt from or subject to a reduced rate of
        withholding tax, becomes subject to taxes because of its failure to
        deliver a form required hereunder, the Borrower shall take such steps as
        such Lender shall reasonably request to assist such Lender to recover
        such taxes.

               (iii) Any Lender claiming any additional amounts payable pursuant
        to this Section 4.06 shall use reasonable efforts (consistent with legal
        and regulatory restrictions) to file any certificate or document
        requested by the Borrower or the Agent or to change the jurisdiction of
        its Applicable Lending Office or to contest any tax imposed if the
        making of such a filing or change or contesting such tax would avoid the
        need for or reduce the amount of any such additional amounts that may
        thereafter accrue and would not, in the sole determination of such
        Lender, be otherwise disadvantageous to such Lender.

                                    ARTICLE V

                                CAPITAL ADEQUACY

        Section 5.01  CAPITAL ADEQUACY; ADDITIONAL COSTS.

        (a) EURODOLLAR REGULATIONS, ETC. The Borrower shall pay directly to each
Lender from time to time such amounts as such Lender may determine to be
necessary to compensate such Lender for any costs which it determines are
attributable to its making or maintaining of any Eurodollar Loans or issuing or
participating in Letters of Credit hereunder or its obligation to make any
Eurodollar Loans or issue or participate in any Letters of Credit hereunder, or
any reduction in any amount receivable by such Lender hereunder in respect of
any of such Eurodollar Loans, Letters of Credit or such obligation (such
increases in costs and reductions in amounts receivable being herein called
"ADDITIONAL COSTS"), resulting from any Regulatory Change which: (i) changes the
basis of taxation of any amounts payable to such Lender under this Agreement or
any Note in respect of any of such Eurodollar Loans or Letters of Credit (other
than taxes imposed on the overall net income of such Lender or of its Applicable
Lending Office for any of such Eurodollar Loans by the jurisdiction in which
such Lender has its principal office or Applicable Lending Office); or (ii)
imposes or modifies any reserve, special deposit, minimum capital, capital ratio
or similar requirements relating to any extensions of credit or other assets of,
or any deposits with or other

                                           - 29 -
<PAGE>
liabilities of such Lender, or the Commitment or Loans of such Lender or the
Eurodollar interbank market; or (iii) imposes any other condition affecting this
Agreement or any Notes (or any of such extensions of credit or liabilities) or
such Lender's Commitment or Loans. Each Lender will notify the Agent and the
Borrower of any event occurring after the Closing Date which will entitle such
Lender to compensation pursuant to this Section 5.01(a) as promptly as
practicable after it obtains knowledge thereof and determines to request such
compensation, and will designate a different Applicable Lending Office for the
Loans of such Lender affected by such event if such designation will avoid the
need for, or reduce the amount of, such compensation and will not, in the
reasonable opinion of such Lender, be disadvantageous to such Lender, provided
that such Lender shall have no obligation to so designate an Applicable Lending
Office located in the United States. If any Lender requests compensation from
the Borrower under this Section 5.01(a), the Borrower may, by notice to such
Lender, suspend the obligation of such Lender to make additional Revolving
Credit Loans of the Type with respect to which such compensation is requested
until the Regulatory Change giving rise to such request ceases to be in effect
(in which case the provisions of Section 5.04 shall be applicable).

        (b) REGULATORY CHANGE. Without limiting the effect of the provisions of
Section 5.01(a), in the event that at any time (by reason of any Regulatory
Change or any other circumstances arising after the Closing Date affecting (A)
any Lender, (B) the Eurodollar interbank market or (C) such Lender's position in
such market), the Eurodollar Rate, as determined in good faith by such Lender,
will not adequately and fairly reflect the cost to such Lender of funding its
Eurodollar Loans, then, if such Lender so elects, by notice to the Borrower and
the Agent, the obligation of such Lender to make additional Eurodollar Loans
shall be suspended until such Regulatory Change or other circumstances ceases to
be in effect (in which case the provisions of Section 5.04 shall be applicable).

        (c) CAPITAL ADEQUACY. Without limiting the effect of the foregoing
provisions of this Section 5.01 (but without duplication), the Borrower shall
pay directly to any Lender from time to time on request such amounts as such
Lender may reasonably determine to be necessary to compensate such Lender or its
parent or holding company for any costs which it determines are attributable to
the maintenance by such Lender or its parent or holding company (or any
Applicable Lending Office), pursuant to any Governmental Requirement following
any Regulatory Change, of capital in respect of its Commitment, its Notes or its
Loans or any interest held by it in any Letter of Credit, such compensation to
include, without limitation, an amount equal to any reduction of the rate of
return on assets or equity of such Lender or its parent or holding company (or
any Applicable Lending Office) to a level below that which such Lender or its
parent or holding company (or any Applicable Lending Office) could have achieved
but for such Governmental Requirement. Such Lender will notify the Borrower that
it is entitled to compensation pursuant to this Section 5.01(c) as promptly as
practicable after it determines to request such compensation.

        (d) COMPENSATION PROCEDURE. Any Lender notifying the Borrower of the
incurrence of additional costs under this Section 5.01 shall in such notice to
the Borrower and the Agent set forth in reasonable detail the basis and amount
of its request for compensation. Determinations and allocations by each Lender
for purposes of this Section 5.01 of the effect of any Regulatory Change
pursuant to Section 5.01(a) or (b), or of the effect of capital maintained
pursuant to Section 5.01(c),

                                           - 30 -
<PAGE>
on its costs or rate of return of maintaining Loans or its obligation to make
Loans or issue Letters of Credit, or on amounts receivable by it in respect of
Loans or Letters of Credit, and of the amounts required to compensate such
Lender under this Section 5.01, shall be conclusive and binding for all
purposes, provided that such determinations and allocations are made on a
reasonable basis. Any request for additional compensation under this Section
5.01 shall be paid by the Borrower within thirty (30) days of the receipt by the
Borrower of the notice described in this Section 5.01(d).

        Section 5.02 LIMITATION ON EURODOLLAR LOANS. Anything herein to the
contrary notwithstanding, if, on or prior to the determination of any Eurodollar
Rate for any Interest Period:

               (i) the Agent determines (which determination shall be
        conclusive, absent manifest error) that quotations of interest rates for
        the relevant deposits referred to in the definition of "Eurodollar Rate"
        in Section 1.02 are not being provided in the relevant amounts or for
        the relevant maturities for purposes of determining rates of interest
        for Eurodollar Loans as provided herein; or

               (ii) the Agent determines (which determination shall be
        conclusive, absent manifest error) that the relevant rates of interest
        referred to in the definition of "Eurodollar Rate" in Section 1.02 upon
        the basis of which the rate of interest for Eurodollar Loans for such
        Interest Period is to be determined are not sufficient to adequately
        cover the cost to the Lenders of making or maintaining Eurodollar Loans;

then the Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to
make additional Eurodollar Loans.

        Section 5.03 ILLEGALITY. Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans hereunder, then such Lender shall promptly notify the Borrower thereof and
such Lender's obligation to make Eurodollar Loans shall be suspended until such
time as such Lender may again make and maintain Eurodollar Loans (in which case
the provisions of Section 5.04 shall be applicable).

        Section 5.04 BASE RATE LOANS PURSUANT TO SECTIONS 5.01, 5.02 AND 5.03.
If the obligation of any Lender to make Eurodollar Loans shall be suspended
pursuant to Sections 5.01, 5.02 or 5.03 ("AFFECTED LOANS"), all Affected Loans
which would otherwise be made by such Lender shall be made instead as Base Rate
Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has
occurred and such Lender so requests by notice to the Borrower, all Affected
Loans of such Lender then outstanding shall be automatically converted into Base
Rate Loans on the date specified by such Lender in such notice) and, to the
extent that Affected Loans are so made as (or converted into) Base Rate Loans,
all payments of principal which would otherwise be applied to such Lender's
Affected Loans shall be applied instead to its Base Rate Loans.

        Section 5.05 COMPENSATION. The Borrower shall pay to each Lender within
thirty (30) days of receipt of written request of such Lender (which request
shall set forth, in reasonable detail, the basis for requesting such amounts and
which shall be conclusive and binding for all purposes

                                           - 31 -
<PAGE>
provided that such determinations are made on a reasonable basis), such amount
or amounts as shall compensate it for any loss, cost, expense or liability which
such Lender determines are attributable to:

               (i) any payment, prepayment or conversion of a Eurodollar Loan
        properly made by such Lender or the Borrower for any reason (including,
        without limitation, the acceleration of the Loans pursuant to Section
        10.01) on a date other than the last day of the Interest Period for such
        Loan; or

               (ii) any failure by the Borrower for any reason (including but
        not limited to, the failure of any of the conditions precedent specified
        in Article VI to be satisfied) to borrow, continue or convert a
        Eurodollar Loan from such Lender on the date for such borrowing,
        continuation or conversion specified in the relevant notice given
        pursuant to Section 2.02(c).

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
which would have accrued on the principal amount so paid, prepaid or converted
or not borrowed for the period from the date of such payment, prepayment or
conversion or failure to borrow to the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date specified for such borrowing) at the
applicable rate of interest for such Loan provided for herein over (ii) the
interest component of the amount such Lender would have bid in the London
interbank market for Dollar deposits of leading banks in amounts comparable to
such principal amount and with maturities comparable to such period (as
reasonably determined by such Lender).

        Section 5.06  REPLACEMENT LENDERS.

        (a) If any Lender has notified the Borrower and the Agent of its
incurring additional costs under Section 5.01 or has required the Borrower to
make payments for Taxes under Section 4.06, then the Borrower may, unless such
Lender has notified the Borrower and the Agent that the circumstances giving
rise to such notice no longer apply, terminate, in whole but not in part, the
Commitment of such Lender (other than the Agent) (the "TERMINATED LENDER") at
any time upon five (5) Business Days' prior written notice to the Terminated
Lender and the Agent (such notice referred to herein as a "NOTICE OF
TERMINATION").

        (b) In order to effect the termination of the Commitment of the
Terminated Lender, the Borrower shall: (i) obtain an agreement with one or more
Lenders to increase their Commitment or Commitments and/or (ii) request any one
or more other banking institutions to become parties to this Agreement in place
and instead of such Terminated Lender and agree to accept a Commitment or
Commitments; PROVIDED, HOWEVER, that such one or more other banking institutions
are reasonably acceptable to the Agent and become parties by executing an
Assignment (the Lenders or other banking institutions that agree to accept in
whole or in part the Commitment of the Terminated Lender being referred to
herein as the "REPLACEMENT LENDERS"), such that the aggregate increased

                                           - 32 -
<PAGE>
and/or accepted Commitments of the Replacement Lenders under clauses (i) and
(ii) above equal the Commitment of the Terminated Lender.

        (c) The Notice of Termination shall include the name of the Terminated
Lender, the date the termination will occur (the "LENDER TERMINATION DATE"), and
the Replacement Lender or Replacement Lenders to which the Terminated Lender
will assign its Commitment and, if there will be more than one Replacement
Lender, the portion of the Terminated Lender's Commitment to be assigned to each
Replacement Lender.

        (d) On the Lender Termination Date, (i) the Terminated Lender shall by
execution and delivery of an Assignment assign its Commitment to the Replacement
Lender or Replacement Lenders (pro rata, if there is more than one Replacement
Lender, in proportion to the portion of the Terminated Lender's Commitment to be
assigned to each Replacement Lender) indicated in the Notice of Termination and
shall assign to the Replacement Lender or Replacement Lenders each of its Loans
(if any) then outstanding and participation interests in Letters of Credit (if
any) then outstanding (pro rata as aforesaid), (ii) the Terminated Lender shall
endorse its Notes, payable without recourse, representation or warranty to the
order of the Replacement Lender or Replacement Lenders (pro rata as aforesaid),
(iii) the Replacement Lender or Replacement Lenders shall purchase the Notes
held by the Terminated Lender (pro rata as aforesaid) at a price equal to the
unpaid principal amount thereof plus interest, facility and other fees, and
other amounts owing under the Loan Documents accrued and unpaid to the Lender
Termination Date, and (iv) the Replacement Lender or Replacement Lenders will
thereupon (pro rata as aforesaid) succeed to and be substituted in all respects
for the Terminated Lender with like effect as if becoming a Lender pursuant to
the terms of Section 12.06(b), and the Terminated Lender will have the rights
and benefits of an assignor under Section 12.06(b). To the extent not in
conflict, the terms of Section 12.06(b) shall supplement the provisions of this
Section 5.06(d). For each assignment made under this Section 5.06, the
Replacement Lender shall pay to the Agent the processing fee provided for in
Section 12.06(b). The Borrower will be responsible for the payment of any
breakage costs, as set forth in Section 5.05, associated with termination of the
Terminated Lender and assignment of Loans and Commitments to Replacement
Lenders.

                                   ARTICLE VII

                         REPRESENTATIONS AND WARRANTIES

        The Borrower represents and warrants to the Agent and the Lenders that
(each representation and warranty herein is given as of the Closing Date and
shall be deemed repeated and reaffirmed on the dates of each borrowing and
issuance, renewal, extension or reissuance of a Letter of Credit as provided in
Section 6.02):

        Section 7.01 CORPORATE EXISTENCE. Each of the Borrower and each
Subsidiary: (i) is a corporation duly organized, legally existing and in good
standing under the laws of the jurisdiction of its incorporation; (ii) has all
requisite corporate power, and has all material governmental licenses,
authorizations, consents and approvals necessary to own its assets and carry on
its business as now being or as proposed to be conducted; and (iii) is qualified
to do business in all jurisdictions in which the nature of the business
conducted by it makes such qualification necessary and where failure so to
qualify would have a Material Adverse Effect.

        Section 7.02 FINANCIAL CONDITION. The audited consolidated balance sheet
of the Borrower and its Consolidated Subsidiaries as at December 31, 1996 and
the related consolidated statement of income, stockholders' equity and cash flow
of the Borrower and its Consolidated Subsidiaries for the fiscal year ended on
said date, with the opinion thereon of Coopers & Lybrand heretofore furnished to
the Agent and the unaudited consolidated balance sheet of the Borrower and its
Consolidated Subsidiaries as at June 30, 1997 and their related consolidated
statements of income, stockholders' equity and cash flow of the Borrower and its
Consolidated Subsidiaries for the six month period ended on such date heretofore
furnished to the Agent, are complete and correct and fairly present the
consolidated financial condition of the Borrower and its Consolidated
Subsidiaries as at said dates and the results of its operations for the fiscal
year and the six month period on said dates, all in accordance with GAAP, as
applied on a consistent basis (subject, in the case of the interim financial
statements, to normal year-end adjustments). Neither the Borrower nor any
Subsidiary has on the Closing Date any material Debt, contingent liabilities,
liabilities for taxes, unusual forward or long-term commitments or unrealized or
anticipated losses from any unfavorable commitments, except as referred to or
reflected or provided for in the Financial Statements or in SCHEDULE 7.02. Since
June 30, 1997, there has been no change or event having a Material Adverse
Effect. Since the date of the Financial Statements, neither the business nor the
Properties of the Borrower or any Subsidiary have been materially and adversely
affected as a result of any fire, explosion, earthquake, flood, drought,
windstorm, accident, strike or other labor disturbance, embargo, requisition or
taking of Property or cancellation of contracts, permits or concessions by any
Governmental Authority, riot, activities of armed forces or acts of God or of
any public enemy. The unaudited pro forma projected consolidated balance sheet
of the Borrower and its Consolidated Subsidiaries at the Closing Date, and the
unaudited pro forma projected consolidated statement of income of the Borrower
and its Consolidated Subsidiaries as of the Closing Date, heretofore furnished
to the Agent, fairly present the pro forma projected consolidated financial
condition of the Borrower and its Consolidated Subsidiaries as at the Closing
Date. Borrower repaid or caused to be repaid all Subordinated Debt outstanding
at the time of the initial public offering of the capital stock of the Borrower
that raised at least $25,000,000, including, without limitation, the Debt

                                           - 37 -
<PAGE>
incurred pursuant to the Securities Purchase Agreement dated as of December 19,
1995, among the Borrower and each of the investors signatory thereto, as amended
by the Waiver and Amendment dated as of May 31, 1996 and by Amendment No. 1
dated as of June 16, 1997, the loan made to the Borrower in the principal amount
of $2,000,000 arranged by Pecks Management Partners, Ltd., and the balance of
the deferred compensation owed by the Borrower to Jack H. Castle, D.D.S.
pursuant to the Deferred Compensation Agreement dated as of December 19, 1995,
between the Borrower and Jack H. Castle, D.D.S., as amended, and such Deferred
Compensation Agreement has been terminated.

        Section 7.03 LITIGATION. At the Closing Date there is no litigation,
legal, administrative or arbitral proceeding, investigation or other action of
any nature pending or, to the knowledge of the Borrower threatened against or
affecting the Borrower or any Subsidiary which could reasonably be expected to
have a Material Adverse Effect.

        Section 7.04 NO BREACH. Neither the execution and delivery of the Loan
Documents, nor compliance with the terms and provisions hereof will conflict
with or result in a breach of, or require any consent which has not been
obtained as of the Closing Date under, the respective charter or by-laws of the
Borrower or any Subsidiary, or any Governmental Requirement or any material
agreement or instrument to which the Borrower or any Subsidiary is a party or by
which it is bound or to which it or its Properties are subject, or constitute a
default under any such material agreement or instrument, or result in the
creation or imposition of any Lien upon any of the revenues or assets of the
Borrower or any Subsidiary pursuant to the terms of any such material agreement
or instrument other than the Liens created by the Loan Documents.

        Section 7.05 AUTHORITY. The Borrower and each Subsidiary have all
necessary corporate power and authority to execute, deliver and perform its
obligations under the Loan Documents to which it is a party; and the execution,
delivery and performance by the Borrower and each Subsidiary of the Loan
Documents to which it is a party, have been duly authorized by all necessary
corporate action on its part; and the Loan Documents constitute the legal, valid
and binding obligations of the Borrower and each Subsidiary, enforceable in
accordance with their terms.

        Section 7.06 APPROVALS. No authorizations, approvals or consents of, and
no filings or registrations with, any Governmental Authority are necessary for
the execution, delivery or performance by the Borrower or any Subsidiary of the
Loan Documents to which it is a party or for the validity or enforceability
thereof, except for the recording and filing of the Security Instruments as
required by this Agreement.

        Section 7.07 USE OF LOANS. The proceeds of the Revolving Credit Loans
shall be used to provide financing for New Acquisitions, for capital
expenditures and for general working capital purposes of the Borrower; PROVIDED,
HOWEVER, that not more than $5,000,000 of the Revolving Credit Loans (in the
aggregate) may be used by the Borrower for general working capital purposes. The
Term Loans shall be used to refinance existing Debt. The Borrower is not engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose, whether immediate, incidental or ultimate, of buying or
carrying margin stock (within the meaning of Regula tion G, T, U or X of the
Board of Governors of the Federal Reserve System) and no part of the proceeds of
any Loan hereunder will be used to buy or carry any margin stock.

        (b) Each Plan is, and has been, maintained in substantial compliance
with ERISA and, where applicable, the Code.

        (c) No act, omission or transaction has occurred which could result in
imposition on the Borrower, any Subsidiary or any ERISA Affiliate (whether
directly or indirectly) of (i) either a civil penalty assessed pursuant to
section 502(c), (i) or (l) of ERISA or a tax imposed pursuant to Chapter 43 of
Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under
section 409 of ERISA.

        (d) No liability to the PBGC (other than for the payment of current

Affiliate to be incurred with respect to any Plan. No ERISA Event with respect
to any Plan has occurred.

        (e) Full payment when due has been made of all amounts which the
Borrower, any Subsidiary or any ERISA Affiliate is required under the terms of
each Plan or applicable law to have paid as contributions to such Plan, and no
accumulated funding deficiency (as defined in section 302 of ERISA and section
412 of the Code), whether or not waived, exists with respect to any Plan.

        (f) The actuarial present value of the benefit liabilities under each
Plan which is subject to Title IV of ERISA does not, as of the end of the
Borrower's most recently ended fiscal year, exceed the current value of the
assets (computed on a plan termination basis in accordance with Title IV of
ERISA) of such Plan allocable to such benefit liabilities. The term "actuarial
present value of the benefit liabilities" shall have the meaning specified in
section 4041 of ERISA.

        (g) None of the Borrower, any Subsidiary or any ERISA Affiliate
sponsors, maintains, or contributes to an employee welfare benefit plan, as
defined in section 3(1) of ERISA, including, without limitation, any such plan
maintained to provide benefits to former employees of such entities, that may
not be terminated by the Borrower, a Subsidiary or any ERISA Affiliate in its
sole discretion at any time without any material liability.

        (h) None of the Borrower, any Subsidiary or any ERISA Affiliate
sponsors, maintains or contributes to, or has at any time in the preceding six
calendar years, sponsored, maintained or contributed to, any Multiemployer Plan.

        (i) None of the Borrower, any Subsidiary or any ERISA Affiliate is
required to provide security under section 401(a)(29) of the Code due to a Plan
amendment that results in an increase in current liability for the Plan.

        Section 7.09 TAXES. Each of the Borrower and its Subsidiaries has filed
all United States Federal income tax returns and all other tax returns which are
required to be filed by them and have

                                           - 39 -
<PAGE>
paid all material taxes due pursuant to such returns or pursuant to any
assessment received by the Borrower or any Subsidiary. The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of taxes
and other governmental charges are, in the opinion of the Borrower, adequate. No
tax lien has been filed and, to the knowledge of the Borrower, no claim is being
asserted with respect to any such tax, fee or other charge.

        Section 7.10  TITLES, ETC.

        (a) Each of the Borrower and its Subsidiaries and each Acquired Entity

        (b) All leases and agreements necessary for the conduct of the business
of the Borrower and its Subsidiaries and each Acquired Entity are valid and
subsisting, in full force and effect and there exists no default or event or
circumstance which with the giving of notice or the passage of time or both
would give rise to a default under any such lease or leases, which would affect
in any material respect the conduct of the business of the Borrower and its
Subsidiaries.

        (c) The licenses, rights, Properties and other assets presently owned,
leased or licensed by the Borrower and its Subsidiaries and each Acquired
Entity, include all rights, Properties and other assets necessary to permit the
Borrower and its Subsidiaries and each Acquired Entity to conduct their business
in all material respects in the same manner as its business has been conducted
prior to the Closing Date.

        (d) All of the assets and Properties of the Borrower and its
Subsidiaries and each Acquired Entity which are reasonably necessary for the
operation of its business are in good working condition and are maintained in
accordance with prudent business standards.

        Section 7.11 NO MATERIAL MISSTATEMENTS. No written information,
statement, exhibit, certificate, document or report furnished to the Agent and
the Lenders (or any of them) by the Borrower or any Subsidiary in connection
with the negotiation of this Agreement contained any material misstatement of
fact or omitted to state a material fact or any fact necessary to make the
statement contained therein not materially misleading in the light of the

for compliance with all requirements of law and of all agreements to which the
Borrower or any Subsidiary is a party; are valid, outstanding and enforceable
policies; provide adequate insurance coverage in at least such amounts and
against at least such risks (but including in any event public liability) as are

each Subsidiary; will remain in full force and effect through the respective
dates set forth in SCHEDULE 7.19 without the payment of additional premiums; and

respect to its assets or operations, nor has its coverage been limited below
usual and customary policy limits, by an insurance carrier to which it has
applied for any such insurance or with which it has carried insurance during the
last three years. In the event that a new Subsidiary is formed and an advance is
requested under the Revolving Credit Loans, and the Lenders approve such
advance, Borrower will provide the Agent with a new, updated SCHEDULE 7.19.

limitation, any purchase, sale, lease or exchange of Property or the rendering
of any service, with any Affiliate unless such transactions are otherwise
permitted under this Agreement, are in the ordinary course of its business and
are upon fair and reasonable terms no less favorable to it than it would obtain
in a comparable arm's length transaction with a Person not an Affiliate.

        Section 9.18 SUBSIDIARIES. The Borrower shall not create any additional
Subsidiaries or permit any Subsidiary to do so without prior written approval of

of them under, this Agreement, or for the value, validity, effectiveness,
genuineness, execution, effectiveness, legality, enforceability or sufficiency
of this Agreement, any Note or any other document referred to or provided for
herein or for any failure by the Borrower or any other Person (other than the
Agent) to perform any of its obligations hereunder or thereunder or for the
existence, value, perfection or priority of any collateral security or the
financial or other condition of the Borrower, its Subsidiaries or any other
obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be
required to initiate or conduct any litigation or collection proceedings
hereunder; and (iv) shall not be responsible for any action taken or omitted to
be taken by it hereunder or under any other document or instrument referred to
or provided for herein or in connection herewith including its own ordinary
negligence, except for its own gross negligence or willful misconduct. The Agent
may employ agents, accountants, attorneys and experts and shall not be
responsible for the negligence or misconduct of any such agents, accountants,
attorneys or experts selected by it in good faith or any action taken or omitted
to be taken in good faith by it in accordance with the advice of such agents,
accountants, attorneys or experts. The Agent may deem and treat the payee of any
Note as the holder thereof for all purposes hereof unless and until a written
notice of the assignment or transfer thereof permitted hereunder shall have been
filed with the Agent. The Agent is authorized to release any collateral that is
permitted to be sold or released pursuant to the terms of the Loan Documents.

        Section 11.02 RELIANCE BY AGENT. The Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telex, telecopier, telegram or cable) reasonably believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Agent.

        Section 11.03 DEFAULTS. The Agent shall not be deemed to have knowledge
of the occurrence of a Default (other than the non-payment of principal of or
interest on Loans or of fees or failure to reimburse for Letter of Credit
drawings) unless the Agent has received notice from a Lender or the Borrower
specifying such Default and stating that such notice is a "Notice of Default."
In the event that the Agent receives such a notice of the occurrence of a
Default, the Agent shall give

                                           - 57 -
<PAGE>
prompt notice thereof to the Lenders. In the event of a payment Default, the
Agent shall give each Lender prompt notice of each such payment Default.

        Section 11.04 RIGHTS AS A LENDER. With respect to its Commitments and
the Loans made by it and its participation in the issuance of Letters of Credit,
NationsBank (and any successor acting as Agent) in its capacity as a Lender
hereunder shall have the same rights and powers hereunder as any other Lender
and may exercise the same as though it were not acting as the Agent, and the
term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include the Agent in its individual capacity. NationsBank (and any successor
acting as Agent) and its Affiliates may (without having to account therefor to
any Lender) accept deposits from, lend money to and generally engage in any kind
of banking, trust or other business with the Borrower (and any of its
Affiliates) as if it were not acting as the Agent, and NationsBank and its
Affiliates may accept fees and other consideration from the Borrower for
services in connection with this Agreement or otherwise without having to
account for the same to the Lenders.

        Section 11.05 INDEMNIFICATION. THE LENDERS AGREE TO INDEMNIFY THE AGENT
AND THE ISSUING BANK RATABLY IN ACCORDANCE WITH THEIR PERCENTAGE SHARES FOR THE
INDEMNITY MATTERS AS DESCRIBED IN SECTION 12.03 TO THE EXTENT NOT INDEMNIFIED OR
REIMBURSED BY THE BORROWER UNDER SECTION 12.03, BUT WITHOUT LIMITING THE
OBLIGATIONS OF THE BORROWER UNDER SAID SECTION 12.03 AND FOR ANY AND ALL OTHER
LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER WHICH MAY BE
IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE AGENT OR THE ISSUING BANK IN ANY
WAY RELATING TO OR ARISING OUT OF: (I) THIS AGREEMENT, THE SECURITY INSTRUMENTS
OR ANY OTHER DOCUMENTS CONTEMPLATED BY OR REFERRED TO HEREIN OR THE TRANSACTIONS
CONTEMPLATED HEREBY, BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS
CONTINUING, NORMAL ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE
OF ITS AGENCY DUTIES HEREUNDER OR (II) THE ENFORCEMENT OF ANY OF THE TERMS OF
THIS AGREEMENT, ANY SECURITY INSTRUMENT OR OF ANY SUCH OTHER DOCUMENTS; WHETHER
OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE
OR CONCURRENT NEGLIGENCE OF THE AGENT OR THE ISSUING BANK, PROVIDED THAT NO
LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE FROM
THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE AGENT OR THE ISSUING BANK.

        Section 11.06 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender
acknowledges and agrees that it has, independently and without reliance on the
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Borrower and its
decision to enter into this Agreement, and that it will, independently and
without reliance upon the Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own analysis and decisions in taking or not taking action under this Agreement.
The Agent shall not be required to keep itself informed as to the performance or
observance by the Borrower of this Agreement, the Notes, the Security
Instruments or any other document referred to or provided for herein or to
inspect the properties or books of the Borrower. Except for notices, reports and
other documents and information expressly required to be furnished to the
Lenders by the Agent hereunder and copies of the documents required

                                           - 58 -
<PAGE>
to be provided to the Agent under Article VI, the Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Borrower (or any
of its Affiliates) which may come into the possession of the Agent or any of its
Affiliates. In this regard, each Lender acknowledges that Vinson & Elkins L.L.P.
is acting in this transaction as special counsel to the Agent only, except to
the extent otherwise expressly stated in any legal opinion or any Loan Document.
Each Lender will consult with its own legal counsel to the extent that it deems
necessary in connection with the Loan Documents and the matters contemplated
therein.

        Section 11.07 ACTION BY AGENT. Except for action or other matters
expressly required of the Agent hereunder, the Agent shall in all cases be fully
justified in failing or refusing to act hereunder unless it shall (i) receive
written instructions from the Majority Lenders (or all of the Lenders as
expressly required by Section 12.04) specifying the action to be taken, and (ii)
be indemnified to its satisfaction by the Lenders against any and all liability
and expenses which may be incurred by it by reason of taking or continuing to
take any such action. The instructions of the Majority Lenders (or all of the
Lenders as expressly required by Section 12.04) and any action taken or failure
to act pursuant thereto by the Agent shall be binding on all of the Lenders. If
a Default has occurred and is continuing, the Agent shall take such action with
respect to such Default as shall be directed by the Majority Lenders (or all of
the Lenders as required by Section 12.04) in the written instructions (with
indemnities) described in this Section 11.07, provided that, unless and until
the Agent shall have received such directions, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interests of the Lenders.
In no event, however, shall the Agent be required to take any action which
exposes the Agent to personal liability or which is contrary to this Agreement
and the Security Instruments or applicable law.

        Section 11.08 RESIGNATION OR REMOVAL OF AGENT. Subject to the
appointment and acceptance of a successor Agent as provided below, the Agent may
resign at any time by giving notice thereof to the Lenders and the Borrower, and
the Agent may be removed at any time with or without cause by the Majority
Lenders. Upon any such resignation or removal, the Majority Lenders shall have
the right to appoint a successor Agent. If no successor Agent shall have been so
appointed by the Majority Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Agent's giving of notice of
resignation or the Majority Lenders' removal of the retiring Agent, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent. Upon
the acceptance of such appointment hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation or removal hereunder as Agent, the provisions of
this Article XI and Section 12.03 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Agent.

                                  MISCELLANEOUS

        Section 12.01 WAIVER. No failure on the part of the Agent or any Lender
to exercise and no delay in exercising, and no course of dealing with respect
to, any right, power or privilege under any of the Loan Documents shall operate
as a waiver thereof, nor shall any single or partial exercise of any right,
power or privilege under any of the Loan Documents preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

        Section 12.02 NOTICES. All notices and other communications provided for

NationsBank; or, as to any party, at such other address as shall be desig nated
by such party in a notice to each other party. Except as otherwise provided in

personally delivered or, in the case of a mailed notice, three (3) Business Days

demand provided that if the Borrower provides a defense, the Indemnified Party
shall bear its own cost of defense unless there is a conflict between the
Borrower and such Indemnified Party.

        (D) THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES

                                           - 62 -
<PAGE>
prior written consent; provided that (i) no amendment, modification or waiver
which extends the final maturity of the Loans, postpones the scheduled payment
date of any amount owing under any Loan Document, increases the Aggregate
Maximum Revolving Credit Amounts, modifies the Borrowing Base, forgives the
principal amount of any Indebtedness outstanding under this Agreement, releases
any guarantor of the Indebtedness or releases all or substantially all of the
collateral, reduces the interest rate applicable to the Loans or the fees
payable to the Lenders generally, affects Section 2.03(a), this Section 12.04 or
Section 12.06(a) or modifies the definition of "Majority Lenders" or "Revolving
Credit Termination Date" shall be effective without consent of all Lenders; (ii)
no amendment, modification or waiver which increases the Maximum Revolving
Credit Amount or the Term Commitment of any Lender shall be effective without
the consent of such Lender; and (iii) no amendment, modification or waiver which
modifies the rights, duties or obligations of the Agent shall be effective
without the consent of the Agent.

        Section 12.05 SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns.

        Section 12.06  ASSIGNMENTS AND PARTICIPATIONS.

        (a) The Borrower may not assign its rights or obligations hereunder or
under the Notes or any Letters of Credit without the prior consent of all of the
Lenders and the Agent.

        (b) Any Lender may, upon the written consent of the Agent and, if no
Event of Default has occurred and is continuing, the Borrower (which consent
will not be unreasonably withheld), assign to one or more assignees all or a
portion of its rights and obligations under this Agreement; PROVIDED, HOWEVER,
that (i) any such assignment shall be in the amount of at least $5,000,000 or
such lesser amount to which the Borrower has consented and (ii) the assignee or
assignor shall pay to the Agent a processing and recordation fee of $3,000 for
each assignment. Any such assignment will become effective upon the execution
and delivery to the Agent of the assignment and the consent of the Agent and the
Borrower, if applicable. Promptly after receipt of an executed Assignment, the
Agent shall send to the Borrower a copy of such executed Assignment. Upon
receipt of such executed Assignment, the Borrower, will, at its own expense,
execute and deliver new Notes to the assignor and/or assignee, as appropriate,
in accordance with their respective interests as they appear. Upon the
effectiveness of any assignment pursuant to this Section 12.06(b), the assignee
will become a "Lender," if not already a "Lender," for all purposes of this
Agreement and the Security Instruments. The assignor shall be relieved of its
obligations hereunder to the extent of such assignment (and if the assigning
Lender no longer holds any rights or obligations under this Agreement, such
assigning Lender shall cease to be a "Lender" hereunder except that its rights
under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected). The Agent will
prepare on the last Business Day of each month during which an assignment has
become effective pursuant to this Section 12.06(b), a new ANNEX I giving effect
to all such assignments effected during such month, and will promptly provide
the same to the Borrower and each of the Lenders.

        (c) Each Lender may transfer, grant or assign participations in all or
any part of such Lender's interests hereunder pursuant to this Section 12.06(c)
to any Person, PROVIDED that: (i) such Lender shall remain a "Lender" for all
purposes of this Agreement and the transferee of such

                                           - 63 -
<PAGE>
participation shall not constitute a "Lender" hereunder; and (ii) no participant
under any such participation shall have rights to approve any amendment to or
waiver of any of the Loan Documents except to the extent such amendment or
waiver would (x) forgive any principal owing on any Indebtedness or extend the
final maturity of the Loans, (y) reduce the interest rate (other than as a
result of waiving the applicability of any post-default increases in interest
rates) or fees applicable to any of the Commitments or Loans or Letters of
Credit in which such participant is participating, or postpone the payment of
any thereof, or (z) release any guarantor of the Indebtedness or release all or
substantially all of the collateral (except as provided in the Loan Documents)
supporting any of the Commitments or Loans or Letters of Credit in which such
participant is participating. In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the
Security Instruments (the participant's rights against the granting Lender in
respect of such participation to be those set forth in the agreement with such
Lender creating such participation), and all amounts payable by the Borrower
hereunder shall be determined as if such Lender had not sold such participation,
PROVIDED that such participant shall be entitled to receive additional amounts
under Article V on the same basis as if it were a Lender and be indemnified
under Section 12.03 as if it were a Lender. In addition, each agreement creating
any participation must include an agreement by the participant to be bound by
the provisions of Section 12.15.

        (d) The Lenders may furnish any information concerning the Borrower in
the possession of the Lenders from time to time to assignees and participants
(including prospective assignees and participants); provided that, such Persons
agree to be bound by the provisions of Section 12.15.

        (e) Notwithstanding anything in this Section 12.06 to the contrary, any
Lender may assign and pledge its Notes to any Federal Reserve Bank as collateral
security pursuant to Regulation A of the Board of Governors of the Federal
Reserve System and any operating circular issued by such Federal Reserve System
and/or such Federal Reserve Bank. No such assignment and/or pledge shall release
the assigning and/or pledging Lender from its obligations hereunder.

        (f) Notwithstanding any other provisions of this Section 12.06, no
transfer or assignment of the interests or obligations of any Lender or any
grant of participations therein shall be permitted if such transfer, assignment
or grant would require the Borrower to file a registration statement with the
SEC or to qualify the Loans under the "Blue Sky" laws of any state.

        Section 12.07 INVALIDITY. In the event that any one or more of the
provisions contained in any of the Loan Documents, the Letter of Credit
Agreements, or the Letters of Credit shall, for any reason, be held invalid,
illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of the Notes, this
Agreement or any Security Instrument.

        Section 12.08 COUNTERPARTS. This Agreement may be executed in any number
of counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

shall be deemed to refer to the applicable Section of this Agreement unless
otherwise stated herein. Any reference herein to an exhibit or schedule shall be

        Section 12.10 SURVIVAL. The obligations of the parties under Section
4.06, Article V, and Sections 11.05 and 12.03 shall survive the repayment of the
Loans and the termination of the Commitments. To the extent that any payments on
the Indebtedness or proceeds of any collateral are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to
a trustee, debtor in possession, receiver or other Person under any bankruptcy
law, common law or equitable cause, then to such extent, the Indebtedness so
satisfied shall be revived and continue as if such payment or proceeds had not
been received and the Agent's and the Lenders' Liens, security interests,
rights, powers and remedies under this Agreement and each Security Instrument
shall continue in full force and effect. In such event, each Security Instrument
shall be automatically reinstated and the Borrower shall take such action as may
be reasonably requested by the Agent and the Lenders to effect such
reinstatement.

THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY
HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (IV)
ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE SECURITY
INSTRUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.13.

        Section 12.14 INTEREST. It is the intention of the parties hereto that
each Lender shall conform strictly to usury laws applicable to it. Accordingly,
if the transactions contemplated hereby would be usurious as to any Lender under
laws applicable to it (including the laws of the United States of America and
the State of Texas or any other jurisdiction whose laws may be mandatorily
applicable to such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any
of the Loan Documents or any agreement entered into in connection with or as
security for the Notes, it is agreed as follows: (i) the aggregate of all
consideration which constitutes interest under law applicable to any Lender that
is contracted for, taken, reserved, charged or received by such Lender under any
of the Loan Documents or agreements or otherwise in connection with the Notes
shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if
theretofore paid shall be credited by such Lender on the principal amount of the
Indebtedness (or, to the extent that the principal amount of the Indebtedness
shall have been or would thereby be paid in full, refunded by such Lender to the
Borrower); and (ii) in the event that the maturity of the Notes is accelerated
by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or
permitted prepayment, then such consideration that constitutes interest under
law applicable to any Lender may never include more than the maximum amount
allowed by such applicable law, and excess interest, if any, provided for in
this Agreement or otherwise shall be canceled automatically by such Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be
credited by such Lender on the principal amount of the Indebtedness (or, to the
extent that the principal amount of the Indebtedness shall have been or would
thereby be paid in full, refunded by such Lender to the Borrower). All sums paid
or agreed to be paid to any Lender for the use, forbearance or detention of sums
due hereunder shall, to the extent permitted by law applicable to such Lender,
be amortized,

                                           - 66 -
<PAGE>
prorated, allocated and spread throughout the full term of the Loans evidenced
by the Notes until payment in full so that the rate or amount of interest on
account of any Loans hereunder does not exceed the maximum amount allowed by
such applicable law. If at any time and from time to time (i) the amount of
interest payable to any Lender on any date shall be computed at the Highest
Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in
respect of any subsequent interest computation period the amount of interest
otherwise payable to such Lender would be less than the amount of interest
payable to such Lender computed at the Highest Lawful Rate applicable to such
Lender, then the amount of interest payable to such Lender in respect of such
subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to such Lender until the total amount of interest
payable to such Lender shall equal the total amount of interest which would have
been payable to such Lender if the total amount of interest had been computed
without giving effect to this Section 12.14. To the extent that Article
5069-1.04 of the Texas Revised Civil Statutes is relevant for the purpose of
determining the Highest Lawful Rate, such Lender elects to determine the
applicable rate ceiling under such Article by the indicated weekly rate ceiling
from time to time in effect.

        Section 12.15 CONFIDENTIALITY. In the event that the Borrower provides
to the Agent or the Lenders written confidential information belonging to the
Borrower, if the Borrower shall denominate such information in writing as
"confidential", the Agent and the Lenders shall thereafter maintain such
information in confidence in accordance with the standards of care and diligence
that each utilizes in maintaining its own confidential information. This
obligation of confidence shall not apply to such portions of the information
which (i) are in the public domain, (ii) hereafter become part of the public
domain without the Agent or the Lenders breaching their obligation of confidence
to the Borrower, (iii) are previously known by the Agent or the Lenders from
some source other than the Borrower, (iv) are hereafter developed by the Agent
or the Lenders without using the Borrower's information, (v) are hereafter
obtained by or available to the Agent or the Lenders from a third party who owes
no obligation of confidence to the Borrower with respect to such information or
through any other means other than through disclosure by the Borrower, (vi) are
disclosed with the Borrower's consent, (vii) must be disclosed either pursuant
to any Governmental Requirement or to Persons regulating the activities of the
Agent or the Lenders, or (viii) as may be required by law or regulation or order
of any Governmental Authority in any judicial, arbitration or governmental
proceeding. Further, the Agent or a Lender may disclose any such information to
any other Lender, any independent consultants, any independent certified public
accountants, any legal counsel employed by such Person in connection with this
Agreement or any Security Instrument, including without limitation, the
enforcement or exercise of all rights and remedies thereunder, or any assignee
or participant (including prospective assignees and participants) in the Loans;
PROVIDED, HOWEVER, that the Agent or the Lenders shall receive a confidentiality
agreement from the Person to whom such information is disclosed such that said
Person shall have the same obligation to maintain the confidentiality of such
information as is imposed upon the Agent or the Lenders hereunder.
Notwithstanding anything to the contrary provided herein, this obligation of
confidence shall cease three (3) years from the date the information was
furnished, unless the Borrower requests in writing at least thirty (30) days
prior to the expiration of such three year period, to maintain the
confidentiality of such information for an additional three year period. The
Borrower waives any and all other rights it may have to confidentiality as
against the Agent and the Lenders arising by contract, agreement, statute or law
except as expressly stated in this Section 12.15.

        Section 12.17 BINDING ARBITRATION.

        (A) ANY CONTROVERSY OR CLAIM BETWEEN OR AMONG THE PARTIES HERETO,
INCLUDING BUT NOT LIMITED TO, THOSE ARISING OUT OF OR RELATING TO THIS
AGREEMENT, THE NOTES OR THE SECURITY INSTRUMENTS, INCLUDING ANY CLAIM OR
CONTROVERSY OF ANY KIND BASED ON OR ARISING IN TORT, SHALL BE DETERMINED BY

APPLICABLE, APPLICABLE STATE LAW), THE RULES OF PRACTICE AND PROCEDURE FOR THE
ARBITRATION OF COMMERCIAL DISPUTES OR JUDICIAL ARBITRATION AND MEDIATION
SERVICES, INC. ("J.A.M.S."), AND THE RULES SET FORTH IN SECTION 12.17(B) BELOW.
IN THE EVENT OF ANY INCONSISTENCY, THE RULES SET FORTH IN SECTION 12.17(B) BELOW
SHALL CONTROL. JUDGMENT UPON ANY ARBITRATION AWARD MAY BE ENTERED IN ANY COURT
HAVING JURISDICTION. ANY PARTY TO THE NOTES OR ANY OTHER SECURITY INSTRUMENT MAY
BRING AN ACTION, INCLUDING A SUMMARY OR EXPEDITED PROCEEDING, TO COMPEL
ARBITRATION OR ANY CONTROVERSY OR CLAIM TO WHICH EITHER THE NOTES, THIS
AGREEMENT OR ANY OTHER SECURITY INSTRUMENT APPLIES IN ANY COURT HAVING
JURISDICTION OVER SUCH ACTION.

        (B) THE ARBITRATION SHALL BE CONDUCTED IN THE CITY OF HOUSTON, TEXAS AND
ADMINISTERED BY J.A.M.S. WHO WILL APPOINT AN ARBITRATOR. IF J.A.M.S. IS UNABLE
OR LEGALLY PRECLUDED FROM ADMINISTERING THE ARBITRATION, THEN THE AMERICAN
ARBITRATION ASSOCIATION WILL SERVE. ALL ARBITRATION HEARINGS WILL BE COMMENCED
WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION, AND THE ARBITRATOR SHALL, ONLY
UPON A SHOWING OF CAUSE, BE PERMITTED TO EXTEND THE COMMENCEMENT OF SUCH
HEARINGS FOR AN ADDITIONAL 60 DAYS.

        (C) NOTHING IN THIS AGREEMENT SHALL BE DEEMED TO (I) LIMIT THE
APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF LIMITATION OR REPOSE OR
ANY WAIVERS CONTAINED IN THIS AGREEMENT, THE NOTES, THE GUARANTY AGREEMENT OR
THE OTHER SECURITY INSTRUMENTS; (II) BE A WAIVER BY ANY LENDER OF THE PROTECTION
AFFORDED TO IT BY 12 U.S.C. SS.91 OR ANY SUBSTANTIALLY EQUIVALENT STATE LAW; OR

REMEDIES SUCH AS, BUT NOT LIMITED, INJUNCTIVE RELIEF, WRIT OF POSSESSION OR THE
APPOINTMENT OF A RECEIVER. ANY LENDER MAY EXERCISE SUCH SELF HELP RIGHTS,
FORECLOSE UPON COLLATERAL, OR OBTAIN SUCH PROVISIONAL OR ANCILLARY REMEDIES
BEFORE, DURING OR AFTER THE PENDENCY OF ANY ARBITRATION PROCEEDING BROUGHT
PURSUANT TO THE NOTES, THIS AGREEMENT OR THE OTHER SECURITY INSTRUMENTS. NEITHER
THE EXERCISE OF SELF HELP REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN
ACTION FOR FORECLOSURE OR PROVISIONAL OR ANCILLARY REMEDIES SHALL CONSTITUTE A
WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE CLAIMANT IN SUCH ACTION, TO
ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM OCCASIONING THE RESORT TO SUCH
REMEDIES.

DISCLOSURES OF INFORMATION REQUIRED IN THE ORDINARY COURSE OF ITS BUSINESS OR BY
APPLICABLE LAW OR REGULATION.

        (E) NOTHING IN THIS AGREEMENT SHALL BE DEEMED TO LIMIT THE RIGHT OF THE
BORROWER TO OBTAIN INJUNCTIVE RELIEF AGAINST ANY LENDER PRIOR TO OR DURING THE
PENDENCY OF ANY ARBITRATION PROCEEDING BASED ON VIOLATIONS BY ANY LENDER OF ANY
LENDER'S AGREEMENTS WITH THE BORROWER, SO LONG AS THE INJUNCTIVE RELIEF IS
LIMITED TO RESTRAINING ANY LENDER FROM EXERCISING ITS RIGHTS AND REMEDIES UNTIL
THE ARBITRATION PROCEEDING (IN PROCESS OR INITIATED BY THE BORROWER OR ANY
LENDER IN CONJUNCTION WITH THE REQUEST FOR SUCH INJUNCTIVE RELIEF) HAS BEEN
COMPLETED AND ARBITRATION AWARD HAS BEEN MADE.

                             SUBORDINATION AGREEMENT

       This Subordination Agreement dated as of _____________ ("AGREEMENT"), is
made by ____________________________ ("SUBORDINATED CREDITOR"), and CASTLE
DENTAL CENTERS, INC., a Delaware corporation ("DEBTOR"), in favor of NATIONSBANK

                                         INTRODUCTION

       Reference is made to the Credit Agreement dated as of November 7, 1997
(as modified from time to time, the "CREDIT AGREEMENT"), among the Debtor, the
Agent and the banks party thereto ("SENIOR CREDITORS"). It is a condition
precedent to the Senior Creditors' permitting the Debtor to incur the
indebtedness represented by the Subordinated Note that the Subordinated Creditor
enter into this Agreement. In consideration of the foregoing and for other good
and valuable consideration, the Subordinated Creditor, the Debtor, and the
Senior Creditors hereby agree as follows:

Section 1. DEFINITIONS.  The following terms shall have the following meanings:

       "EVENT OF DEFAULT" means any "Default" or "Event of Default" as defined
in, and which may occur under, the Credit Agreement.

       "LOAN DOCUMENTS" shall have the meaning specified by the Credit
Agreement.

       "SENIOR DEBT" means (a) all principal, interest, fees, reimbursements,
indemnifications, and other amounts now or hereafter owed by the Debtor to
Senior Creditors under the Credit Agreement, the Loan Documents, and any other
instrument or agreement related thereto and (b) any increases, extensions, and
rearrangements of the foregoing obligations under any amendments, supplements,
and other modifications of the documents and agreements creating the foregoing
obligations.

       "SUBORDINATED DEBT" means all present and future indebtedness,
liabilities, and obligations of any kind owed by the Debtor to the Subordinated
Creditor, including debt obligations, equity obligations, and other contractual
obligations requiring payments of any kind to be made to the Subordinated
Creditor, whether such indebtedness, liabilities, and obligations are absolute
or contingent, joint, several, or independent, arising by operation of law or
contract, created directly with the Subordinated Creditor or acquired by
assignment, participation, or otherwise, or direct or indirect (including
indebtedness, liabilities, and obligations of the Debtor to the Subordinated
Creditor as a result of either's membership in any partnership, syndicate,
association, or other group, and whether incurred by the Debtor as principal,
guarantor, surety, endorser, accommodation party, or otherwise). Subordinated
Debt specifically includes the Subordinated Note.

       "SUBORDINATED NOTE" means the $___________ Note dated as of
_______________, made by the Debtor and payable to the order of the Subordinated
Creditor, as the same may be increased,

<PAGE>
extended, rearranged, amended, supplemented, and otherwise modified from time to
time in accordance with this Agreement.

Section 2. TERMS OF SUBORDINATION. Unless and until the Senior Debt shall have
been irrevocably paid in full and the Senior Creditors shall have no commitment
to extend further Senior Debt, the payment and performance of the Subordinated
Debt is hereby made expressly subordinate and junior in right of payment and
performance to the prior payment and performance of all obligations and
liabilities under the Senior Debt to the extent and in the manner set forth in
this Section 2:

       2.1     LIMITATION ON PAYMENTS.

               (a) No payment or prepayment of any sum on the Subordinated Debt,
whether by acceleration or otherwise, shall be made, if at the time of such
payment, prepayment, or immediately after giving effect thereto there shall
exist a default in the payment or prepayment with respect to any of the Senior
Debt, or immediately after giving effect thereto (i) there shall exist a default
in the payment or prepayment of the principal or interest with respect to any of
the Senior Debt or (ii) there shall have occurred, or after giving effect to
such payment there shall occur, an Event of Default (other than an Event of
Default in the payment of prepayment of principal or interest with respect to
any of the Senior Debt) permitting the Senior Creditors to accelerate the
maturity thereof (with notice, lapse of time, or both) and such Event of Default
shall not have been cured or waived to the satisfaction of the Senior Creditors.

               (b) If at any time there shall occur an Event of Default, the
Subordinated Creditor shall not be entitled to receive any payment on the
Subordinated Debt before the earlier of (i) cure of the Event of Default to the
satisfaction of the Senior Creditors or (ii) the irrevocable payment in full of
the Senior Debt and the termination of all commitments to extend Senior Debt.

               (c) In the event that any Subordinated Debt is declared due and
payable before their expressed maturity because of the occurrence of an event of
default (under circumstances when the provisions of the foregoing paragraphs (a)
or (b) are not applicable), the Senior Creditors shall be entitled to receive
payment in full of all principal, interest, and other sums outstanding in
connection with the Senior Debt before the Subordinated Creditor is entitled to
receive any payment on account of such Subordinated Debt.

               (d) Any payments received by the Subordinated Creditor in
violation of this Agreement shall be held by the Subordinated Creditor in trust
for the benefit of the Senior Creditors and shall be immediately turned over to
the Agent in the form received (together with any necessary endorsements) for
application to the Senior Debt until all outstanding Senior Debt has been
irrevocably paid in full.

       2.2 SUBORDINATION ON LIQUIDATION. Upon any receivership, insolvency
proceeding, bankruptcy proceeding, assignment for the benefit of creditors,
reorganization, arrangement with creditors, sale of assets for creditors,
dissolution, liquidation, or marshalling of the assets of the Debtor (each, a
"BANKRUPTCY EVENT"), all amounts due with respect to the Senior Debt shall be
irrevocably paid in full before the Subordinated Creditor shall be entitled to
collect or receive any payment with respect to the Subordinated Debt. Any
payments received by the Subordinated Creditor in such proceedings shall be held
by the Subordinated Creditor in trust for the benefit of the

                                            H-2
<PAGE>
Senior Creditors and shall be immediately turned over to the Agent in the form
received (together with any necessary endorsements) for application to the
Senior Debt until all outstanding Senior Debt has been irrevocably paid in full.

       2.3 SUBORDINATION OF LIENS. The Subordinated Creditor will not create,
assume, or suffer to exist any lien, security interest, or assignment of
collateral securing the repayment of the Subordinated Debt. Any such judgment
lien, and any other lien, security interest, or assignment existing in violation
of the foregoing shall be fully subordinate to any lien, security interest, or
assignment in favor of the Senior Creditors which secures any of the Senior
Debt. At the request of the Senior Creditors, the Subordinated Creditor and the
Debtor will take any and all steps necessary to fully effect the release of any
such lien, security interest, assignment, or collateral.

       2.4 FURTHER ASSURANCES. The Subordinated Creditor and the Debtor agree to
execute any and all other instruments requested by the Senior Creditors to
further evidence the subordination of the Subordinated Debt to the Senior Debt
as herein provided.

Section 3. SUBORDINATION ABSOLUTE. This is an irrevocable agreement of
subordination and the Senior Creditors may, without notice to any of the parties
hereto and without impairing or releasing the obligations of the Debtor and the
Subordinated Creditor hereunder, (a) create Senior Debt by extending credit
under the Credit Agreement; (b) change the terms of or increase the amount of
the Senior Debt by increasing, extending, rearranging, amending, supplementing,
or otherwise modifying any of the Loan Documents or other instruments or
agreements creating Senior Debt; (c) sell, exchange, release, or otherwise deal
with any collateral securing any Senior Debt; (d) release anyone, including the
Debtor or any guarantor, liable in any manner for the payment or collection of
any Senior Debt; (e) exercise or refrain from exercising any rights against the
Debtor or any other Person; and (f) apply any sums received by any of the Senior
Creditors, from whatever source, to the payment of the Senior Debt.

Section 4.     PROVISIONS REGARDING SUBORDINATED DEBT.

       4.1 There may be no increases, extensions, rearrangements, amendments,
supplements, or other modifications to the Subordinated Note which increase the
principal amount of, increase the interest rate payable on, or accelerate the
scheduled principal and interest payments on the Subordinated Note without the
prior written permission of the Senior Creditors.

       4.2 The Subordinated Creditor will cause all Subordinated Debt to be
evidenced by a note, debenture, instrument, or other writing evidencing the
Subordinated Debt and will inscribe a statement or legend thereon to the effect
that such note, debenture, instrument, or other writing is subordinated to the
Senior Debt in favor of the Senior Creditors in the manner and to the extent set
forth in this Agreement.

       4.3 The Subordinated Creditor shall mark the books of Subordinated
Creditor to show that the Subordinated Debt is subordinated to the Senior Debt

Agreement.

       4.4 The Subordinated Creditor shall not assign or otherwise transfer to
any other person any interest in the Subordinated Debt unless the Subordinated
Creditor causes the assignee or other transferee to execute and deliver to the
Senior Creditors a subordination agreement in substantially the form of this
Agreement or otherwise acknowledges to the reasonable satisfaction of the Senior
Creditors the subordination of the Subordinated Debt in accordance with this
Agreement.

Section 5.     MISCELLANEOUS.

       5.1 To the extent not paid by the Debtor, the Subordinated Creditor shall
reimburse the Senior Creditors for all reasonable expenses of the Senior
Creditors, including reasonable charges and disbursements of legal counsel for
the Senior Creditors, in connection with the execution, amendment, modification,
waiver, and interpretation of this Agreement, and the administration,
preservation, and enforcement of any rights of the Senior Creditors under this
Agreement. To the extent not paid by the Debtor, the Subordinated Creditor shall
indemnify the Senior Creditors against all claims, liabilities, damages, and

of the Debtor under this Agreement. The provisions of this paragraph shall
survive termination of this Agreement.

If any provision in this Agreement is held to be unenforceable, such provision
shall be severed and the remaining provisions shall remain in full force and
effect. The Senior Creditors' remedies under this Agreement shall be cumulative,
and no delay in enforcing this Agreement shall act as a waiver of the Senior
Creditors' rights hereunder. The provisions of this Agreement may be waived or
amended only in a writing signed by all of the parties hereto. This Agreement

assigns and shall inure to the benefit of the Senior Creditors and their

First Amendment or the exhibits hereto, if any, are only for the convenience of

among the parties hereto.
