                                  THE COMPANY
 
     UDC is a managed dental benefits company that is licensed to operate
prepaid dental plans in 25 states and, as of June 30, 1996, provided dental
coverage to approximately 1,175,000 members. The Company offers a comprehensive
range of prepaid dental plans capable of meeting the needs of employer groups of
all sizes as well as individuals. UDC's dentist networks, as of June 30, 1996,
consisted of approximately 3,000 general dentists as well as specialist dentists
providing a broad range of dental services. The Company markets its services
through multiple distribution channels, including a direct sales force of over
70 persons, independent brokers and third-party arrangements with medical health
maintenance organizations ("HMOs"). The Company recently entered into agreements
to acquire five managed dental benefits companies and a multi-state dental
referral plan having approximately 500,000 members in the aggregate at June 30,
1996. See "Pending and Recent Acquisitions."
 
     Managed dental benefits plans are usually offered as an alternative to
traditional dental indemnity insurance, although the Company has the capability
of offering dual choice plans that provide both prepaid and indemnity plans.
Industry sources report that prepaid dental plans are typically priced 20% or
more below comparable indemnity benefits based on 1992 indemnity-industry
statistical information. Prepaid dental plans are offered by employers to
employees frequently on a voluntary-participation basis with all or part of the
premium being paid by the employee. At the time of enrollment, participating
employees and dependents become members of the prepaid dental plan and, under
most of the Company's plans, each member is entitled to select his or her own
dentist from the dentist network. The Company pays the network dentist a fixed
monthly amount, or capitation payment, for each member who selected that
dentist, regardless of the services rendered in any particular month. In
addition, the dentist is paid a separate fee, or copayment, by the member at the
time of service for many of the dental services covered under the plan. Under
the prepaid dental plans of the Company, virtually all covered dental services
are provided through these capitation arrangements, in which the Company bears
little financial risk for either utilization levels or cost of services.
 
     Based on data compiled by the U.S. Office of National Health Statistics,
total expenditures for dental care in the United States grew from approximately
$14.4 billion in 1980 to approximately $43.2 billion in 1993. The number of
people with dental benefits was estimated by the National Association of Dental
Plans to be approximately 125 million in 1995, of which approximately 16% were
covered under a prepaid dental plan. Prepaid dental plans have reportedly grown
from approximately 10.4 million covered members in 1991 to an estimated 19.5
million in 1995, an annual compounded growth rate of approximately 17.0%. The
Company believes the relatively high growth rate for prepaid dental plans is
attributable to: (i) the greater acceptance of managed care by employers and
employees; (ii) the significant price advantage of prepaid dental plans relative
to indemnity plans; (iii) the cost effectiveness to employers of prepaid dental
plans as an employee benefit; and (iv) the growing acceptance of capitated
dental plans by dentists, resulting in improved accessibility and convenience
for members. The Company believes there will continue to be significant growth
for the managed dental benefits industry.
 
     The Company's objective is to be the leading managed dental benefits
company in the United States by both increasing its market share in its current
markets and selectively entering new markets. The Company believes this
objective can be achieved by: (i) offering a full range of prepaid dental plan
benefits designed to meet the needs of small and large employers as well as
individuals; (ii) ensuring quality dental care through a locally managed network
of private practice dentists; (iii) utilizing multiple distribution channels to
access single-market and multi-state employer groups and members of third-party
HMOs; (iv) providing high levels of customer service through local service
representatives and regional customer service centers; and (v) acquiring other
managed dental benefits companies.

                        PENDING AND RECENT ACQUISITIONS
 
     The Company recently entered into definitive agreements to acquire five
managed dental benefits companies operating prepaid dental plans in New Jersey,
Florida, Oklahoma, Missouri, Kansas and Michigan having approximately 440,000
members in the aggregate at June 30, 1996. In addition, the Company recently
entered into a definitive agreement to acquire a company operating a multi-state
dental referral plan having approximately 60,000 members at June 30, 1996. The
companies to be acquired had combined revenues of approximately $35.9 million
for the year ended December 31, 1995 and $21.3 million for the six months ended
June 30, 1996. Upon completion of the acquisitions, the Company will be licensed
to operate prepaid dental plans in four additional states and will be licensed
to operate an indemnity plan in one additional state. The acquisitions are
subject to various conditions, including receipt of regulatory approvals. There
can be no assurance as to whether or when such acquisitions will be completed.
The proposed acquisitions are referred to in this Prospectus as the "Pending
Acquisitions."
 
     Effective February 1, 1996, the Company acquired Associated Health Plans,
Inc., a managed dental benefits company that operated prepaid dental plans in
Arizona having approximately 220,000 members at the time of the acquisition, and
an affiliated management company (collectively, "AHP"). Effective November 1,
1995, the Company acquired U.S. Dental Management, Inc. ("US Dental"), a managed
dental benefits company that operated prepaid dental plans in Arizona, New
Mexico, Nebraska and Colorado having approximately 163,000 members at the time
of the acquisition and that administered a prepaid dental plan owned by a third
party in Nevada. See "Pending and Recent Acquisitions."

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the shares
of Common Stock offered by this Prospectus. This Prospectus contains
forward-looking statements which involve risks and uncertainties. The Company's
actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth in the following risk factors and elsewhere in this Prospectus. See
"Disclosure Regarding Forward-Looking Statements."
 
     Pending and Future Acquisitions. The Company's growth strategy is dependent
in part upon the Company's ability to pursue and complete strategic acquisition
opportunities as they arise. The necessity for regulatory approvals prior to an
acquisition as well as the substantial amount of time and effort required to
evaluate and negotiate a proposed acquisition may result in substantial
uncertainty as to whether a proposed acquisition will be successfully
consummated. In addition, even after an acquisition is consummated, no assurance
can be given that management will be able to successfully and efficiently
integrate and operate the acquired business or that unforeseen problems will not
arise requiring financial commitments or management efforts not contemplated in
connection with such acquisition. The Pending Acquisitions are subject to
receipt of regulatory approvals and other conditions that may not occur or that
may occur only if the terms of the acquisition vary from the terms described
herein. No assurance can be given that the Company will be able to successfully
implement its growth strategy through acquisitions, or that any acquisition,
including the Pending Acquisitions, will be consummated and successfully
integrated into the Company's operations. Any delay or failure to successfully
assimilate such acquisitions could result in cash expenditures and increased
demands on management's time and could have a material adverse effect on the
Company's business, financial condition and results of operations and on the
price of the Common Stock. One of the Pending Acquisitions involves a dental
practice management company which manages dental clinics operated by a licensed
dentist. The laws of the state in which the dental clinics are located prohibit
dentists from sharing fees with non-dentists and prohibits non-dentist entities
from practicing dentistry. Although the Company believes the operations of the
dental practice company are and will be in material compliance with existing
applicable laws, the structure of the management relationship between the
Company and the dentist has not been the subject of any state regulatory
interpretations. In addition, the Company has not previously engaged in the
dental practice management business. See "Business -- Business Strategy" and
"Pending and Recent Acquisitions."
 
     Regulation. State insurance laws and other governmental regulations
establish various licensing, operational, financial and other requirements
relating to the prepaid dental plan business. State insurance departments and
other regulatory agencies are typically empowered to interpret such laws and
promulgate regulations applicable to the prepaid dental plan business. The laws
and regulations relating to the health care industry in general, and prepaid
dental plans specifically, are rapidly developing and have been the subject of
numerous past and present proposals which, if adopted, could adversely affect
the Company's business. Such proposals have included proposals that would
require the Company to admit "any willing provider" to its dental networks,
create mandatory minimum capitation payments to dental providers and specify
minimum loss ratios or mandate schedules of benefits. In addition, the Company's
insurance company subsidiary is subject to numerous laws and regulations
applicable to insurance companies generally. The Company is unable to predict
the extent to which changes to existing laws and regulations will be adopted or
the effect that any such changes may have on the Company's business. The
Company's ability to conduct its business in additional states is subject to
regulatory approvals required in connection with either acquisitions of existing
dental plan businesses or the application of the Company to conduct its existing
business in additional states. Approvals to acquire another licensed prepaid
dental plan business often require six months or longer to obtain, while
licenses and approvals necessary to commence operations of the Company's
existing business in an additional state can require two years or longer to
obtain. In addition, no assurance can be given that the Company's applications
for any such licenses or approvals will be granted. In the event any such
licenses or approvals are not granted, the Company's plans to expand in
additional states would be adversely affected. See "Business -- Business
Strategy" and "-- Government Regulation."
 
     Medicare/Medicaid Programs. The Company contracts with certain medical HMOs
that provide health services to members under the Medicare or Medicaid programs
administered by certain state agencies. The
 
                                        6
<PAGE>   8
 
Company provides the dental benefits coverage under such plans of the medical
HMOs. The medical HMOs receive reimbursement under either the Medicare or
Medicaid programs for the benefits provided. As a result, the availability of
such reimbursement or decreases in the level of reimbursement or changes in
regulatory requirements could have a significant impact on the decisions of the
medical HMOs to continue to offer dental benefits. In addition, in the event
that the contracts between such medical HMOs and the state agencies are
terminated or not renewed, such termination or nonrenewal would also terminate
the Company's contract with such medical HMO as a provider for dental benefits.
The membership of one of the Pending Acquisitions consists primarily of Medicaid
members of medical HMOs. See "Business -- Government Regulation."
 
     Competition. The Company competes not only with other companies offering
prepaid dental plans similar to those offered by the Company, but also with
numerous other types of businesses in the health care industry, such as
insurance companies offering both prepaid dental plans and indemnity insurance,
medical HMOs offering dental benefit plans, self-funded employer plans,
preferred provider organizations ("PPOs") and dental referral plans. The Company
believes that the competition from all of such sources will continue to increase
in the future and that insurance companies and HMOs in particular will continue
to seek to enter the managed dental benefits business and expand their dental
care markets. Many of the Company's competitors are better known to the public
and have substantially greater financial and other resources than those of the
Company. Price considerations have been a significant competitive factor in the
past and the Company believes pricing will continue to be a significant
competitive factor in the future, especially with respect to contracts awarded
on the basis of competitive bidding. No assurance can be given that the Company
will be able to compete effectively in the future. See
"Business -- Competition."
 
     Dentist Relationships. The Company's business strategy is dependent to a
large extent upon the Company's continued maintenance of a large network of
quality general and specialty dentists in each of the Company's markets.
Generally, the Company and network dentists enter into nonexclusive contracts
that can be terminated by either party with limited notice (generally 90 days).
Primarily for such reasons, the Company did not allocate for financial statement
purposes any portion of the consideration paid in the acquisitions of US Dental
and AHP to the dentist networks of the acquired companies. The Company's
business may be adversely affected if the Company is unable to establish and
maintain contracts with an adequate number of dentists in any market. See
"Business -- Dentist Networks" and "Pending and Recent
Acquisitions -- Acquisition Accounting Principles."
 
     Specialty Care and Indemnity Benefits. Under many of the prepaid dental
plans offered by the Company, specialist dental care by specialist dentists is
made available to members. Specialist dentists are reimbursed by the Company on
a discounted, fee-for-service basis and are not reimbursed on a capitated basis.
Accordingly, the Company retains the risk for the payment of specialist care
benefits in such situations. In the event that the utilization of specialist
care benefits increases under the outstanding plans of the Company, it could
substantially adversely affect the profitability of the Company. With the
acquisition of United Dental Care Insurance Company ("UDCIC") as part of the
acquisition of International Dental Health, Inc. ("IDH") in 1994, the Company
for the first time became involved in the operation of an indemnity insurance
carrier subject to underwriting risk. The Company's present strategy regarding
UDCIC is, in situations where the employer declines to use the Company's dual
choice products, to primarily offer its indemnity policy to employer groups with
greater than 250 employees. To the extent additional members select the UDCIC
indemnity policy, UDCIC would become subject to additional underwriting risk.
One of the Pending Acquisitions involves the acquisition of another indemnity
insurance company through which a prepaid dental plan is operated in one state.
Capital requirements applicable to insurers such as UDCIC may require capital
contributions in the future to the extent earnings from operations are
insufficient to satisfy these requirements. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
     Arizona Regulatory Issues. On May 24, 1996, the Arizona Department of
Insurance filed a Notice of Administrative Hearing against the Company alleging
that the Company consummated its acquisition of AHP in January 1996 without
complying with the requirements of the Arizona Insurance Holding Company Act
(the "Act"). AHP is licensed in Arizona as a prepaid dental plan organization.
The Company did not make a filing under the Act because the Company's
interpretation is that the Act does not apply to AHP since AHP is
 
                                        7
<PAGE>   9
 
not an "insurer" as defined by and subject to the Act. The Notice seeks fines of
up to $50,000 for each violation against the Company and any officer or director
of the Company who knowingly violated the Act, and also seeks an order directing
compliance with the Act in connection with the AHP acquisition. The Arizona
Department of Insurance has broad powers to seek other remedies, including
injunctive relief and license revocation. There can be no assurance as to what
relief may ultimately be sought or obtained by the Arizona Department of
Insurance. The Company has filed an answer denying the allegations. A final
determination against the Company could have a material adverse effect on the
Company. See "Business -- Legal Proceedings."
 
     Anti-takeover Effect of Regulatory and Charter Provisions. State insurance
laws applicable to the Company typically require regulatory approval for any
proposed change of control of the Company. Generally, a change of control would
be deemed to result if anyone acquired 10% or more of the outstanding voting
stock of the Company, although regulatory authorities generally have discretion
to determine whether a change of control in a particular case would occur
whether or not 10% of the voting stock of the Company is acquired. Therefore, no
one can acquire beneficial ownership of 10% or more of the outstanding Common
Stock of the Company, whether pursuant to this offering, open market purchases
or otherwise, without obtaining prior regulatory approval. Such regulatory
approval requirement could also apply to the solicitation of proxies to vote 10%
or more of the outstanding Common Stock and therefore could impair the ability
of a stockholder to conduct a proxy contest. The Company could seek a regulatory
hearing with respect to any stockholder proposal to acquire beneficial ownership
or proxies for 10% or more of the Company's Common Stock, and any stockholder
that fails to obtain regulatory approval in such circumstances may be subject to
regulatory sanctions including the possibility of a divestiture order. In
addition, failure to comply with such regulatory requirements could result in
adverse consequences to the Company. Certain provisions of the Company's
Certificate of Incorporation and Bylaws, certain sections of the Delaware
General Corporation Law, and the ability of the Board of Directors to issue
shares of Preferred Stock and to establish the voting rights, preferences and
other terms thereof without further action by the stockholders, may be deemed to
have an anti-takeover effect and may discourage takeover attempts not first
approved by the Board of Directors and also could delay or frustrate the removal
of incumbent directors, even if such takeover or removal would be beneficial to
stockholders. These provisions also could discourage or make more difficult a
merger, tender offer or proxy contest, even if such events would be beneficial
to the interests of stockholders. The Delaware General Corporation Law imposes
restrictions upon certain acquirors (including their affiliates and associates)
of 15% or more of the Company's Common Stock. See "Business -- Government
Regulation," "Description of Capital Stock -- Certain Provisions of Certificate
of Incorporation and Bylaws" and "-- Business Combinations."
 
     Possible Control by Existing Stockholders. Upon consummation of this
offering, the Company's executive officers and directors will, in the aggregate,
beneficially own approximately 21.3% of the then outstanding Common Stock
(approximately 20.0% if the Underwriters' over-allotment option is exercised in
full). As a result, these stockholders, acting together, will be able to
influence significantly and possibly control most matters requiring approval by
the stockholders of the Company, including the election of directors. Such a
concentration of ownership may have the effect of delaying or preventing a
change in control of the Company, including transactions in which stockholders
might otherwise receive a premium for their shares over then current market
prices. See "Management," "Principal Stockholders" and "Description of Capital
Stock."
 
     Dividends. The Company has never paid cash dividends 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 cash dividends in the
foreseeable future. In addition, future bank borrowings may limit the ability of
the Company to pay, or may prohibit the payment of, cash dividends. Applicable
regulatory requirements may also restrict the ability of certain operating
subsidiaries of the Company to pay dividends. See "Dividend Policy,"
"Capitalization," "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Credit Facilities," and "Business -- Governmental
Regulation."
 
     Risks Associated with Intangible Assets. At June 30, 1996, approximately
$41.7 million, or 55.0%, of the Company's total assets were intangible assets.
As adjusted for this offering, approximately 29.0% of the Company's total assets
at June 30, 1996 would have been intangible assets. Giving effect to the Pending

Acquisitions as if such transactions occurred at June 30, 1996, approximately
$95.9 million, or 65.7%, of the Company's total assets (as adjusted for this
offering) would have been intangible assets. In the event of a sale or
liquidation of the Company, there could be no assurance that the value of such
intangible assets would be realized. In addition, any significant decrease in
the value of such intangible assets could have a material adverse effect on the
Company. See "Pending and Recent Acquisitions" and "Unaudited Pro Forma
Condensed Combined Financial Statements."
 
     Possible Volatility of Stock Price. The stock market has experienced
significant price and volume fluctuations that have affected the market price
for many health care companies and that have often been unrelated to the
operating performance of such companies. The trading price of the Common Stock
may also be subject to significant fluctuations in response to variations in
quarterly operating results, the gain or loss of significant contracts, changes
in management, future announcements concerning the Company, legislative or
regulatory changes, general trends in the industry and other events or factors.

                                USE OF PROCEEDS
 
     The net proceeds from the sale of the 2,000,000 shares of Common Stock
offered by the Company hereby are estimated to be $70.3 million, based upon an
assumed offering price of $37.50 per share (the last reported sale price of the
Common Stock on the Nasdaq National Market on September 13, 1996) and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company. The Company intends to use
approximately $58.5 million of such net proceeds to fund the Pending
Acquisitions and approximately $4.6 million to pay certain amounts owed under
agreements entered into in connection with the IDH, US Dental and AHP
acquisitions. The remaining net proceeds to the Company will be used for general
corporate purposes including future acquisitions and working capital. The
Company currently has no agreements or understandings relating to any
acquisitions other than the Pending Acquisitions. Until needed, the net proceeds
of this offering will be invested in short-term investment grade, interest
bearing obligations. See "Pending and Recent Acquisitions" and "Certain
Transactions."
 
     Most of the Pending Acquisitions are anticipated to be completed after the
completion of this offering. However, none of the Pending Acquisitions are
subject to completion of this offering, and this offering is not subject to
completion of any of the Pending Acquisitions. The Company intends to obtain a
commitment for a $35 million line of credit with an unaffiliated bank to finance
certain of the Pending Acquisitions if they are consummated prior to completion
of this offering. The Company believes based on discussions with such bank that
it will be able to obtain such line of credit. The Company also believes that it
will be able to increase such line of credit to $50 million if necessary to
finance, together with available cash of the Company, all the Pending
Acquisitions if they are consummated prior to completion of this offering. If
any of the Pending Acquisitions are consummated prior to the completion of this
offering, the Company intends to utilize such line of credit to fund such
acquisitions. In that event, the loan will be repaid in full out of the net
proceeds of this offering. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Credit Facilities" and "Pending
and Recent Acquisitions."

                          PRICE RANGE OF COMMON STOCK
 
     The Common Stock of the Company has been included for quotation in the
Nasdaq National Market under the symbol "UDCI" since the Company's initial
public offering of Common Stock on September 21, 1995. Prior to that time, there
was no public market for the Common Stock. The following tables set forth the
high and low closing prices for the Common Stock for the periods indicated as
reported by the Nasdaq National Market:

     On September 13, 1996, the last reported sale price of the Common Stock was
$37.50 per share, and there were approximately 93 holders of record.
 
                                DIVIDEND POLICY
 
     The Company has not paid or declared any cash dividends on its Common Stock
since its inception. The Company currently intends to retain all future earnings
for use in the expansion and operation of its business. In addition, future
borrowings may limit the Company's ability to pay cash dividends. It is
anticipated that the line of credit financing that may be used to finance the
Pending Acquisitions will contain a restriction on the payment of dividends. Any
payments of cash dividends in the future will depend upon the financial
condition, capital requirements and earnings of the Company, limitations on
dividend payments by subsidiaries of the Company under applicable state laws,
and such other factors as the Board of Directors may deem relevant. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources," "-- Credit Facilities" and
"Business -- Government Regulation."

    acquisitions were made when compared to the prior period.
 
     Total membership has grown at a compounded annual growth rate of 109% from
1993 to 1995. Membership growth is concentrated during employer group benefits
enrollment periods generally occurring in the first and fourth quarters of each
year. Membership growth excluding acquisitions has slowed as compared to the
prior periods primarily as a result of higher than expected sales force turnover
and management's emphasis on acquisition opportunities during the current year.
The Company is currently addressing these issues through increased focus on
mid-size and large employer groups, modified incentives in sales force
compensation and increased emphasis on sales through independent brokers.
 
     The Company began operations in Texas in 1986 and expanded to Ohio in 1990
and Missouri in 1993. Since September 1994, the Company has acquired three
companies which had approximately 843,000 members in the aggregate as of the
respective acquisition dates. In addition, the Pending Acquisitions had
approximately 500,000 members in the aggregate as of June 30, 1996.

  Revenues
 
     The Company's revenues are primarily derived from managed benefits premiums
for the prepaid dental plans offered by the Company and, to a lesser extent,
from indemnity premiums received by a subsidiary of the Company. The table below
sets forth the Company's revenue components as a percentage of total revenue for
the periods indicated:

</TABLE>
 
     The revenue contribution from indemnity increased to 21.0% of revenues in
1995 primarily as a result of having a full year of revenues from the dental
indemnity insurance subsidiary acquired on September 1, 1994. The Company had no
indemnity premiums prior to that date. The Company expects revenue from
indemnity products to represent a lower percentage of total revenue in the
future as the Company continues to emphasize prepaid dental plans.
 
     The Company's product pricing varies based on the type of plan, the
services provided (both general and specialty) and the amount of member
copayment. In addition, pricing varies by marketplace based on employer and
employee preference and competition. Pricing also may vary as a result of
different pricing terms of the plans in effect at companies when acquired by
UDC. As a result, per member pricing can fluctuate based on product mix,
shifting marketplace preferences and acquisition timing. As contracts are
renewed, the Company seeks to improve profitability on renewed plans by
increasing pricing, by offering plans with additional services at higher prices
and margins and by offering higher margin plans with fewer services at lower
costs. The Company estimates that premium rate increases have generally averaged
less than 3.5% per year during the three year period ended December 31, 1995.
 
  Dental Services Expense Ratio
 
     The following table sets forth the dental services expense ratios (dental
services expense as a percentage of premium revenue) for the Company's managed
benefit plans for the periods indicated:

          Total dental services expense ratio.......... 43.3     54.2     60.0     60.6     60.7
</TABLE>
 
     The dental services expense ratio for the managed benefit plans increased
during the last three fiscal years and the latest six month period as a result
of integrating acquisitions that had higher dental services expense ratios. Some
of the companies acquired by UDC offered plans that paid dentists a percentage
of premiums higher than the plans of UDC. The Company expects prepaid dental
services expense ratios on such plans to improve in the future as acquired
contracts are converted to the Company's plans and less profitable contracts are
not renewed. The dental services expense ratio for the indemnity plans has
improved in the six months ended June 30, 1996 as compared to the prior period
primarily as a result of the Company's efforts to standardize its indemnity
products and the Company's emphasis on product pricing and profitability.

  Prior Acquisitions
 
     Effective September 1, 1994, the Company completed the acquisition of IDH
for $14.3 million in cash and additional payments of $5.4 million over the six
year period beginning September 16, 1994. Effective November 1, 1995, the
Company completed the acquisition of US Dental for $1.3 million in cash at the
closing, deferred payments of $1.0 million over the three-year period commencing
November 30, 1995, and a promissory note in the amount of $10.3 million which
was paid in January 1996. In addition, on February 1, 1996, the Company
completed the acquisition of AHP for $14.3 million in cash at the closing and
deferred payments of $600,000 over the three-year period commencing February 22,
1996. See "Pending and Recent Acquisitions -- Recent Acquisitions."
 
     The acquisitions of IDH, US Dental and AHP increased the Company's
enrollment by approximately 843,000 members, further increased UDC's market
presence in existing markets, permitted the Company to offer its prepaid dental
plans in 17 new states and augmented the Company's product line by adding an
indemnity insurance business. These acquisitions have resulted in greater
penetration of new accounts within UDC's current markets and currently allow the
Company to market its dental benefit programs to a broader customer base on a
multi-state level.

SIX MONTHS ENDED JUNE 30, 1996 AND 1995
 
     Revenues. Managed benefits revenues increased by $13.9 million, or 47.8%,
to $43.1 million in 1996 from $29.2 million in 1995. Interest income and other
revenue increased $0.2 million. The increase in premium revenues was primarily a
result of an increase in the number of members. During the first six months of
1996, managed benefits membership increased from 861,051 at December 31, 1995 to
1,099,508 at June 30, 1996, including an increase of approximately 220,000
members from the AHP acquisition. The increase in the comparable period in 1995
was from 740,984 to 771,714. Indemnity revenues declined from $8.5 million
 
                                       18
<PAGE>   20
 
(22.2% of revenues) to $7.4 million (14.5% of revenues) largely due to the
termination of a large New Mexico group in December 1995.
 
     Dental Services. Dental services expenses increased $7.9 million, or 34.5%,
to $30.7 million in 1996 from $22.8 million in 1995, primarily due to the
increase in membership discussed above. Total dental services as a percentage of
premium revenues remained relatively unchanged at 60.7% of premiums (60.6% in
1995). Dental service expenses for the Company's managed benefits plans, which
consist primarily of capitation payments to general dentists, increased to 58.3%
of managed benefits revenues in 1996, from 54.1% in 1995. The managed benefits
plans offered by US Dental and AHP historically were sold at lower premium
levels than the Company's pre-existing managed benefits plans, thereby resulting
in the payment to general dentists of a relatively higher percentage of
premiums. Claims expense for the indemnity business was 74.7% of indemnity
revenues. See above discussion for additional information concerning trends in
dental expenses.
 
     Sales and Marketing. Sales and marketing expenses increased $0.7 million,
or 14.2%, to $5.7 million in 1996 from $5.0 million in 1995. Sales and marketing
expenses as a percentage of revenue declined to 11.2% in 1996 from 13.2% in
1995. This decrease was largely attributable to the increase in the percentage
of revenues from managed dental benefits plans relative to indemnity plans in
1996 as compared to 1995. Since the indemnity business generates a higher per
member per month revenue than is generated by the managed dental benefits plans,
and a portion of the sales and marketing costs, such as base salaries and
printing costs, are fixed, the expenses as a percentage of revenues decline. In
addition, the commissions paid on the indemnity business are lower as a
percentage of revenues than those paid on the managed dental benefits plans.
 
     General and Administrative. General and administrative expenses increased
$1.7 million, or 24.3%, to $8.7 million in 1996 from $7.0 million in 1995. The
decline in general and administrative expenses as a percentage of revenues to
17.0% in 1996 from 18.4% in 1995 was primarily attributable to efficiencies
achieved through the consolidation of executive staffs and accounting
departments due to the acquisition of IDH, US Dental and AHP. In addition, there
was a decrease in premium taxes as a percentage of revenue because the Company
now generates a greater percentage of its revenues in states that have lower
premium taxes.
 
     Depreciation and Amortization. Depreciation and amortization expenses
increased $0.4 million, or 80.1%, to $1.0 million in 1996 from $0.6 million in
1995. This increase was the result of amortization of the goodwill and
consulting and non-competition agreements attributable to the acquisitions of US
Dental and AHP.
 
     Interest. Interest expense decreased to $0.2 million in 1996 from $0.6
million in 1995. The 1996 interest expense was composed of the imputed interest
on the agreements incurred to finance the Company's acquisitions. The weighted
average interest rate on these agreements during the first six months of 1996
was 7.9%. This weighted average interest rate also includes the fees for letters
of credit related to the agreements.
 
     Taxes. The average tax rate was 36.7% and 39.0% in 1996 and 1995,
respectively. The lower tax rate in 1996 was largely the result of the $0.4
million tax exempt interest income earned on cash balances. During the
comparable period in 1995, the Company did not have significant cash balances
and interest income was fully taxable. The average tax rate was higher than the
statutory Federal tax rate of 34%, primarily as the result of the
non-deductibility of the amortization of goodwill.
 
YEARS ENDED DECEMBER 31, 1995 AND 1994
 
     Revenues. Revenues increased by $41.8 million, or 112.0%, to $79.2 million
in 1995 from $37.4 million in 1994. Of this increase, $2.2 million, or 5.3%, was
attributable to the operations added through the acquisition of US Dental in
November 1995. The remaining $39.6 million increase was a 106.1% increase in
revenues to $77.0 million in 1995 from $37.4 million in 1994, in markets where
the Company had operations in both periods. This increase was primarily a result
of having IDH operations for the full year in 1995 compared to only four months
in 1994 and the increase in the membership numbers. During 1995, members
increased from 740,984 at December 31, 1994 to 937,355 at December 31, 1995. The
increase in the comparable period in 1994 was from 214,455 to 740,984. Interest
income and other revenue increased $1.0 million, or 394.1%, from
 
                                       19
<PAGE>   21
 
$0.3 million to $1.3 million in 1995. This increase was due to the interest
income derived from the cash proceeds of the initial public offering in
September 1995.
 
     Dental Services. Dental services expenses increased $26.6 million, or
132.3%, to $46.7 million in 1995 from $20.1 million in 1994. Total dental
services as a percentage of revenue increased to 59.0% in 1995 from 53.8% in
1994, primarily due to the effect of a higher dental expense loss ratio in the
indemnity insurance business that the Company acquired through IDH. Claims
expense for the indemnity business was 82.3% of indemnity revenues in 1995 as
compared to 82.8% in 1994. Dental service expenses for the Company's managed
benefits plans, which consist primarily of capitation payments to general
dentists, increased to 53.9% of managed benefits revenues in 1995, from 49.2% in
1994. This increase is attributable to the fact that the managed benefits plans
offered by IDH have historically paid general dentists a higher percentage of
premiums than the Company's pre-existing managed benefits plans. It is
management's intention to increase premiums over the next several years, as
market conditions permit, thereby increasing revenues. In most markets, amounts
paid to general dentists will also be increased to maintain the Company's
competitive position and to improve the economics for general dentists.
 
     Sales and Marketing. Sales and marketing expenses increased $3.8 million,
or 67.4%, to $9.6 million in 1995 from $5.8 million in 1994. Sales and marketing
expenses as a percentage of revenue declined to 12.2% in 1995 from 15.4% in
1994. This decrease was largely attributable to the change in product mix from
primarily managed benefits plans in 1994 to a combination of indemnity and
managed benefits plans in 1995, resulting from the acquisition of IDH effective
September 1, 1994. Since the indemnity business generates a higher per-
member-per-month revenue than is generated by the managed benefits plans, and a
portion of the sales and marketing costs, such as base salaries and printing
costs, are fixed, the expenses as a percentage of revenues decline. In addition,
the commissions paid on the indemnity business are lower as a percentage of
revenues than those paid on the managed benefits plans.
 
     General and Administrative. General and administrative expenses increased
$7.7 million, or 109.4%, to $14.8 million in 1995 from $7.1 million in 1994. The
decline in general and administrative expenses as a percentage of revenues to
18.7% in 1995 from 18.9% in 1994 was primarily attributable to efficiencies
achieved through the consolidation of executive staffs and accounting
departments due to the acquisition of IDH. In addition, there was a decrease in
premium taxes as a percentage of revenue because the Company now generates a
greater percentage of its revenues in states that have lower premium taxes.
 
     Depreciation and Amortization. Depreciation and amortization expenses
increased $0.7 million, or 120.0%, to $1.2 million in 1995 from $0.5 million in
1994. Most of this increase was the result of amortization of goodwill and
consulting and non-competition agreements (the "Agreements") attributable to the
acquisitions of IDH and US Dental and the depreciation of the assets acquired.
 
     Interest. Interest expenses increased to $1.0 million in 1995 from $0.4 in
1994. The $1.0 million was composed of the interest on a bank loan incurred in
1994 to finance the IDH acquisition (the "Bank Loan"), a $10.3 million
promissory note maturing January 18, 1996, that was issued in November 1995 as
part of the consideration for the US Dental acquisition (the "Promissory Note"),
and the imputed interest on the consulting and non-competition agreements
incurred to finance the IDH and US Dental acquisitions (the "Agreements"). The
weighted average interest rates on the Bank Loan, the Promissory Note and the
Agreements during 1995 were 9.5%, 4.4% and 8.6%, respectively. These weighted
average interest rates include the effects of amortization of debt issuance
costs and the fees for letters of credit related to the Agreements.
 
     Taxes. The average tax rate was 36.4% and 37.5% in 1995 and 1994,
respectively. In 1995 and 1994, the average tax rate was higher than the
statutory Federal tax rate of 34.0%, primarily as the result of the
nondeductibility of the amortization of goodwill. The average rate decrease from
1994 to 1995 was primarily due to tax exempt interest income in 1995.
 
     Extraordinary Charge. Upon completion of the Company's initial public
offering in September 1995, the Company used a portion of the offering's
proceeds to repay the Bank Loan. This required the write off of the
 
                                       20
<PAGE>   22
 
unamortized debt-financing expenses capitalized in connection with the Bank Loan
incurred to finance the IDH acquisition and the financing obtained (but not
used) for the US Dental acquisition.
 
YEARS ENDED DECEMBER 31, 1994 AND 1993
 
     Revenues. Revenues increased by $20.4 million, or 120.1%, to $37.4 million
in 1994 from $17.0 million in 1993. Of this increase, $16.9 million, or 82.8%,
was attributable to the operations added through the acquisition of IDH
effective September 1, 1994. The remaining $3.5 million was a 20.7% increase in
revenues to $20.5 million in 1994 from $17.0 million in 1993 in markets where
the Company had operations in both periods. This increase was primarily a result
of an increase in the number of members and to a lesser extent, to premium rate
increases. During the year, members increased from 214,455 at December 31, 1993
to 740,984 at December 31, 1994. The increase for all of 1993 was from 160,885
to 214,455.
 
     Dental Services. Dental services expenses increased $12.8 million, or
176.3%, to $20.1 million in 1994 from $7.3 million in 1993. Total dental
services as a percentage of revenues increased to 53.8% in 1994 from 42.9% in
1993 primarily due to the effect of a higher dental expense loss ratio in the
indemnity insurance business that the Company acquired through IDH in September
1994. Claims expense for the indemnity business was 82.8% of indemnity revenues.
Dental service expenses for the Company's managed benefits business, which
consist primarily of capitation to dentists, increased to 49.2% of managed
benefits revenues in 1994 from 43.3% in 1993. This increase is attributable to
the fact that the managed benefits plans offered by IDH have historically paid
dentists a higher percentage of premiums than the Company's pre-existing plans
paid.
 
     Sales and Marketing. Sales and marketing expenses increased $2.7 million,
or 90.3%, to $5.7 million in 1994 from $3.0 million in 1993. Sales and marketing
expenses as a percentage of revenues declined to 15.4% in 1994 from 17.8% in
1993. This decrease was largely attributable to the change in product mix from
managed benefits plans only in 1993 to a combination of indemnity and managed
benefits plans in 1994 as a result of the IDH acquisition. Since the indemnity
business generates a higher per member per month revenue than generated by the
managed benefits plans, and a portion of the sales and marketing costs, such as
base salaries and printing costs, are fixed, the expenses as a percentage of
revenues decline. In addition, the commissions paid on the indemnity business
are lower as a percentage of revenues than those paid on the managed benefits
plans.
 
     General and Administrative. General and administrative expenses increased
$3.5 million, or 94.4%, to $7.1 million in 1994 from $3.6 million in 1993. The
decline in general and administrative expenses as a percentage of revenues to
18.9% in 1994 from 21.4% in 1993 was primarily attributable to efficiencies
achieved through the consolidation of executive staffs and accounting
departments due to the acquisition of IDH. In addition, there was a decrease in
premium taxes as a percentage of revenue because the Company now generates a
greater percentage of its revenues in states that charge lower premium taxes.
 
     Depreciation and Amortization. Depreciation and amortization expenses
increased $0.3 million, or 240.3%, to $0.5 million in 1994 from $0.2 million in
1993. Most of this increase was the result of amortization of goodwill and the
Agreements entered into in connection with the acquisition of IDH and the
depreciation of the assets acquired.
 
     Acquisition-Related Expenses. During 1994, the Company incurred $0.2
million of acquisition-related expenses. These expenses were all due to the
acquisition of IDH in September 1994.
 
     Interest. Interest expenses increased to $0.4 million in 1994 from $0 in
1993. The $0.4 million was entirely attributable to the interest on the Bank
Loan and the imputed interest on the Agreements incurred to finance the IDH
acquisition. The weighted average interest rates on the Bank Loan and the
Agreements during the portion of 1994 subsequent to the IDH acquisition were
8.3% and 8.8%, respectively. These weighted average interest rates include the
effects of amortization of debt issuance costs and the fees for letters of
credit related to the Agreements.
 
     Change in Accounting Principle. During 1993, the Company incurred a minor
charge for the cumulative effect of a change in accounting principle as required
by SFAS 109 for "Accounting for Income Taxes."

</TABLE>
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In September 1995, the Company completed an initial public offering of
2,375,000 shares of its Common Stock at an offering price of $22.00 per share
resulting in net proceeds of approximately $48.0 million. The Company used
approximately $9.9 million of such proceeds for the repayment of all outstanding
indebtedness on the Bank Loan, which had been incurred in 1994 to finance the
acquisition of IDH.
 
     The Company's historical operating cash requirements have been met through
cash provided by operations. Net cash provided by operating activities was $2.9
million for the year ended December 31, 1995. Net cash provided by operating
activities was $0.6 million for the six months ended June 30, 1996, composed of
$1.3 million in cash provided by operating activities in the first quarter of
1996 partially offset by the use of $0.7 million in the second quarter. The
second quarter's use of cash was a result of (i) a change to earlier capitation
payments to certain network dentists that resulted in a one-time increase in
cash outflow and (ii) a change to later collection of prepaid revenues from
certain groups that resulted in a one-time decrease in cash flows. Both changes
were instituted to provide better customer service and had no effect on
operating earnings. The decrease in unearned premiums of $2.2 million and the
decrease in accounts payable, accrued expenses and claims reserves of $2.0
million reflect this one-time impact on cash from operating activities.
 
     The Company's primary cash need after operations is for debt service on the
Agreements entered into as a part of the prior acquisitions. The principal
amount of such indebtedness of the Company at June 30, 1996 was $4.6 million.
The various Agreements have fixed rates of interest ranging from 5.0% to 7.5%
and require aggregate payments of principal and interest of $1.4 million per
year. The $10.3 million Promissory Note was paid in full on January 18, 1996.
 
     Under applicable insurance laws of most states in which the Company
conducts business, the Company's subsidiary operating in the particular state is
required to maintain a minimum level of net worth and reserves. In general,
minimum capital requirements are more stringent for insurance companies, such as
United Dental Care Insurance Company ("UDCIC"). The Company may be required from
time to time to invest funds in one or more of its subsidiaries to meet
regulatory capital requirements. The implementation of risk-based capital
regulations in states having jurisdiction over UDCIC may require that the
Company increase its investment in UDCIC. However, the Company does not believe
that compliance with such regulations will
 
                                       22
<PAGE>   24
 
adversely affect the Company's ability to meet its operating cash requirements.
The Company believes that UDCIC will be able to satisfy such regulations without
the need for significant capital contributions by the Company. Applicable laws
generally limit the ability of the Company's subsidiaries to pay dividends to
the extent that required regulatory capital would be impaired. See
"Business -- Governmental Regulation."
 
     Capital expenditures were $2.2 million during the year ended December 31,
1995 and $2.0 million in the six months ended June 30, 1996. Such expenditures
in 1995 primarily consisted of telephone equipment and the capitalized cost
related to the new information system. In June 1995, the Company entered into a
contract to acquire a new information system to replace its existing system. The
project is currently expected to cost approximately $4.0 million and to be
completed in the fourth quarter of 1996. Capital expenditures, other than the
cost of the new information system, were $0.8 million during the six months
ended June 30, 1996. Such expenditures primarily consisted of computer equipment
and furniture purchased in connection with the integration of US Dental and AHP
into the Company. Capital expenditures for the remainder of 1996, excluding the
costs associated with the new information system, are expected to be
approximately $0.7 million.
 
     The Company believes that cash flow generated by operations will be
sufficient to fund its normal working capital needs and capital expenditures
(other than any acquisitions) for at least the next twelve months.
 
     The Company believes that its operations are not materially affected by
inflation. The Company's principal costs, such as dental services expense and
sales and marketing expenses, are largely related to membership levels and are
therefore variably related to premium revenues. Historically, the Company's rate
of premium increases has been less than the rate of increase in the cost of
dental services in general.
 
CREDIT FACILITIES
 
     Pending Acquisitions Commitment. The Company intends to use the net
proceeds of this offering to finance the Pending Acquisitions most of which are
anticipated to be completed following completion of this offering. However, none
of the Pending Acquisitions are subject to completion of this offering, and this
offering is not subject to completion of any of the Pending Acquisitions. The
Company intends to obtain a commitment for a $35 million line of credit with an
unaffiliated bank to finance certain of the Pending Acquisitions if they are
consummated prior to completion of this offering. The Company believes based on
discussions with such bank that it will be able to obtain such line of credit.
The Company also believes it will be able to increase such line of credit to $50
million if necessary to finance, together with available cash of the Company,
all the Pending Acquisitions if they are consummated prior to completion of this
offering. If any of the Pending Acquisitions are consummated prior to the
completion of this offering, the Company intends to utilize such line of credit
to fund such acquisitions. In that event, the loan will be repaid in full out of
the net proceeds of this offering. The commitment will be subject to various
conditions and, accordingly, there can be no assurance that the Company will be
able to complete such financing, if necessary.
 
     Letters of Credit. The Company has arranged for the issuance of two letters
of credit in the aggregate amount of $4.8 million. The letters of credit secure
the obligations of the Company under certain agreements executed in connection
with the IDH acquisition. The letters of credit decline in amount annually and
expire in September 1998. The Company pays an annual fee equal to 1% of the
amount remaining to be drawn under the letters of credit. The letters of credit
will remain outstanding after the offering.

                                    BUSINESS
 
GENERAL
 
     UDC is a managed dental benefits company that is licensed to operate
prepaid dental plans in 25 states and, as of June 30, 1996, provided dental
coverage to approximately 1,175,000 members. The Company offers a comprehensive
range of prepaid dental plans capable of meeting the needs of employer groups of
all sizes as well as individuals. UDC's dentist networks, as of June 30, 1996,
consisted of approximately 3,000 general dentists as well as specialist dentists
providing a broad range of dental services. The Company markets its services
through multiple distribution channels, including a direct sales force of over
70 persons, independent brokers and third-party arrangements with medical HMOs.
The Company recently entered into agreements to acquire five managed dental
benefits companies and one dental referral plan having approximately 500,000
members in the aggregate as of June 30, 1996. See "Pending and Recent
Acquisitions."
 
     Managed dental benefits plans are usually offered as an alternative to
traditional dental indemnity insurance, although the Company has the capability
of offering dual choice plans that provide both prepaid and indemnity plans.
Industry sources report that prepaid dental plans are typically priced 20% or
more below comparable indemnity benefits based on 1992 indemnity-industry
statistical information. Prepaid dental plans are offered by employers to
employees frequently on a voluntary-participation basis with all or part of the
premium being paid by the employee. At the time of enrollment, participating
employees and dependents become members of the prepaid dental plan and, under
most of the Company's plans, each member is entitled to select his or her own
dentist from the dentist network. The Company pays the network dentist a fixed
monthly amount, or capitation payment, for each member who selected that
dentist, regardless of the services rendered in any particular month. In
addition, the dentist is paid a separate fee, or copayment, by the member at the
time of service for many of the dental services covered under the plan. Under
the prepaid dental plans of the Company, virtually all covered dental services
are provided through these capitation arrangements, in which the Company bears
little financial risk for either utilization levels or cost of services.
 
THE MANAGED DENTAL BENEFITS INDUSTRY
 
  Background
 
     According to the U.S. Office of National Health Statistics, total
expenditures for dental care in the United States grew from approximately $14.4
billion in 1980 to approximately $43.2 billion in 1993. According to the
American Dental Association, there were approximately 138,000 active licensed
dentists engaged in private practice in the United States in 1991. The American
Dental Association estimated that in 1993 approximately 68% of the nation's
private dentists were in solo practice and approximately 20% were in two-person
practices.
 
     Historically, payment for dental services has been on a fee-for-service
basis. Under this system, the individual, or a dental indemnity insurance
company, pays fees established by the dentist for the dental services provided
by the dentist and the dentist has little incentive to control costs or minimize
expenses. The charges for such services generally vary widely among dentists.
Since the individual pays all or a portion of the established fees, the
individual is reluctant to incur the costs of preventive dental care. In
addition, the individual has limited access to information regarding cost and
quality on which to select a dentist.
 
  Dental Indemnity Insurance
 
     The number of individuals in the United States with dental benefits was
estimated by the National Association of Dental Plans to be approximately 125
million in 1994, representing approximately 48% of the total United States
population. Historically, dental coverage was not an employee benefit
customarily provided by employers. The Company believes that dental benefits are
a frequently requested employee benefit. In response to employee demand,
employers have increasingly offered dental coverage to employees usually in the
form of indemnity insurance. According to a 1993 survey performed by Foster
Higgins, an employee benefits consulting firm, approximately 87% of employers
with more than 200 employees, approximately 63% of employers with 50-199
employees and approximately 39% of employers with 10-49 employees offer dental
 
                                       24
<PAGE>   26
 
coverage as an available employee benefit. Dental coverage is typically offered
as a separate benefit from medical coverage with the employer frequently paying
none, or only a portion, of the premium for the dental coverage.
 
     Dental indemnity insurance is similar to medical indemnity insurance in
that the individual or the employer pays a premium for the dental insurance
coverage and the insurance company pays or reimburses the dentist in whole or in
part for the charges for dental services. While dental indemnity insurance
companies have utilized mechanisms to control costs such as limiting charges to
reasonable and customary charges for the community in which the services are
rendered and utilizing preferred providers with whom discounted fee schedules
are negotiated, such mechanisms do not transfer significant risk to the dentist
or provide significant incentives to the dentist to control costs or reduce fees
or to the individual to utilize preventative dental services.
 
  Managed Dental Benefits
 
     Increasing concern with the costs of health care, including dental care,
has resulted in a greater willingness by employers and consumers to consider
managed health care delivery systems. The Company believes that these alternate
delivery systems are able to provide for services, or benefits, at a lower cost,
or premium, than fee-for-service alternatives.
 
     Companies having the management expertise and industry knowledge required
to establish and maintain a network of specialized providers such as dentists
have developed specialized managed delivery systems to provide such health care
services. HMOs, PPOs and other forms of managed health care plans for general
medical services have not customarily devoted the resources to develop specialty
managed delivery systems and frequently subcontract with companies providing
single-specialty managed delivery systems such as the Company's prepaid dental
plans.
 
     According to the National Association of Dental Plans, prepaid dental plans
have grown from approximately 10.4 million covered members in 1991 to an
estimated 19.5 million in 1995, an annual compounded growth rate of
approximately 17.0%. The Company believes the relatively high growth rate for
prepaid dental plans is attributable to: (i) the greater acceptance and
utilization of managed care alternatives by employers and employees to reduce
costs; (ii) the significant price advantage relative to indemnity plans; (iii)
the cost effectiveness to employers of prepaid plans as an employee benefit; and
(iv) the growing acceptance of capitated dental plans by dentists, resulting in
improved accessibility and convenience for members. The number of people with
dental benefits was estimated by the National Association of Dental Plans to be
approximately 125 million in 1995, of which approximately 16% were covered under
prepaid dental plans representing approximately 8% of the total United States
population. The Company believes there is significant growth opportunity for the
managed dental benefits industry.
 
     A prepaid dental plan pays a fixed monthly capitation payment to the
network dentist who provides dental services as needed at either no cost to the
member or at reduced fees (copayments) paid by the member. Consequently, the
risk of high utilization is shifted to the dentist, although generally the
dentist receives copayments for many covered services that are often greater
than the direct costs of the dentist, reducing financial risk. The capitation
method rewards efficient providers who stress routine, preventive care and
control their fixed expenses. In comparison, under the traditional
fee-for-service payment system, the risk of utilization is borne by the insurer
or the consumer, with little incentive to the dentist to be an efficient
provider. The Company believes that the ability of a managed dental benefits
plan to volume purchase, shift risk to providers and manage both the costs and
utilization of dental care typically results in premiums 20% or more below
premiums for a traditional indemnity plan.
 
     In addition, some prepaid dental plans provide for specialty care at fixed
copayments by the member. Unlike medical care, the majority of dental care is
provided by general dentists with some specialty care provided by endodontists
(specialists in root canal therapy), oral surgeons (specialists in extractions),
pedodontists (specialists in dentistry for children) and periodontists
(specialists in gum-related treatment). Companies such as UDC that arrange for
specialist care at fixed copayments are further able to manage the costs and
utilization of dental services through specialist referral authorization
programs and discounted fee
 
                                       25
<PAGE>   27
 
arrangements with specialist dentists. Medium to large employers increasingly
expect comprehensive dental care, including specialty care from prepaid dental
plans, at stipulated copayments comparable to the type of coverage provided by a
general medical plan.
 
     According to the National Association of Dental Plans, the number of
dentists affiliated with prepaid dental plans was approximately 26,000 in 1994
or approximately 19% of all active dentists. The Company believes that
significant growth of prepaid dental plans will continue as a result of: (i)
growing acceptance and participation in such plans by dentists; (ii) greater
acceptance of such plans by consumers who are becoming increasingly aware of the
price advantages, improved service and convenience offered by such plans; and
(iii) recognition by employers that such plans can be used to provide important
employee benefits at little or no cost to the employer. Consequently, the
Company believes prepaid dental plans will be increasingly used to replace more
expensive forms of dental coverage and provide dental coverage to greater
portions of the population that presently have no dental coverage.
 
     The Company believes that the managed dental benefits industry has the
potential for significant growth and is highly fragmented. The National
Association of Dental Plans estimated that, at the beginning of 1994,
approximately 40% of its members operating prepaid dental plans were
single-state companies. The Company believes that large independent managed
dental benefits companies will have a greater opportunity to grow and expand
because of growing interest in multi-state coverage by medium and large
employers and increased use by medical HMOs to contract with large dental plans
to provide dental coverage to the medical HMO members. The Company believes that
large dental plans have the resources and systems required to satisfy demands of
employers and requirements of dentists and achieve economies of scale. The
Company believes that the factors supporting the growth of large dental plans
will give rise to consolidation opportunities.
 
BUSINESS STRATEGY
 
     The Company's goal is to be the leading managed dental benefits company in
the United States with the ability to offer prepaid dental plans to employers of
all sizes. The Company intends to maintain and develop a leadership position
within each of its existing key markets and to strategically enter new markets
that afford significant growth opportunities. At present, the Company is
licensed to operate prepaid dental plans in 25 states (not including four
additional states to be entered through the Pending Acquisitions). The Company
believes that as a large, multi-state managed dental benefits company with
significant management depth and financial resources, the Company will have a
competitive advantage over smaller and single-market companies in gaining market
share and participating in the consolidation of the managed dental benefits
industry. In order to implement its strategy, the Company will:
 
     Offer a Full Range of Comprehensive Dental Benefits Plans. One of the keys
to the Company's success has been its ability to offer a broad range of prepaid
dental plans providing different levels of dental coverage, including specialist
care, tailored to meet the various needs of its customers. The variety of its
prepaid dental plans has enabled the Company to attract both small,
single-market employers and large, multi-state employers, as well as
individuals. In addition, the Company has developed prepaid dental plans that
may be offered in substantially all states where it is licensed so that large,
multi-state employers can provide the same dental coverage to all of their
employees.
 
     Ensure Quality Dental Care Through Accessible Dentist Networks. The
Company's strategy is to be one of the three largest dentist networks in its key
markets, providing a full spectrum of dental care, including specialty care. The
Company believes that having provider relations representatives located in each
of its key markets enhances the quality of its dentist networks. The local
knowledge and expertise provided through these local representatives enables the
Company to develop highly accessible dentist networks convenient for members,
which is an important factor to employers in selecting a prepaid dental plan.
All local efforts are supported by the Company's corporate and regional dental
directors.
 
     Utilize Multiple Distribution Channel Marketing Efforts. The Company
markets its prepaid dental plans to employers through (i) its direct sales force
of over 70 persons focusing on medium to large groups such as multi-state
employers and trade or professional organizations and (ii) a network of
independent insurance brokers who market to smaller employers and individuals.
In addition, the Company markets to third-party
 
                                       26
<PAGE>   28
 
medical HMOs to offer its prepaid dental plans as an additional benefit to
members of the medical HMO. The Company believes that its multiple distribution
channel approach is a competitive advantage that provides the flexibility to
meet the needs of the full spectrum of customers.
 
     Emphasize an Integrated Approach to Customer Service. The Company utilizes
an integrated service approach involving local and regional specialized service
representatives to optimize its operations and product strategy for each target
market. Local offices are maintained in each of the Company's key markets with
specialized sales and service representatives for employer groups and insurance
brokers and with the local provider relations representatives for dentists.
Customer service is performed by regional member service centers, accessed via
an 800-telephone number, with the objective of providing consistent, responsive
and efficient member service.
 
     Acquire Other Managed Dental Benefits Companies. The Company intends to
continue with acquisition efforts to enter target markets and to expand its
market penetration in current markets. The US Dental acquisition in November
1995 resulted in approximately 163,000 additional members, and the AHP
acquisition in January 1996 resulted in approximately 220,000 additional
members. The Pending Acquisitions, if completed, will result in approximately
500,000 additional members (including approximately 60,000 referral plan
members) in the aggregate. The Company currently has no agreements or
understandings relating to any acquisitions other than the Pending Acquisitions.
See "Pending and Recent Acquisitions."
 
BENEFITS PLANS
 
  Managed Dental Plans
 
     The Company offers a full spectrum of managed dental plans ("Plans")
through numerous state-level subsidiaries. The Plans range from lower coverage,
higher copayment plans with low premiums to higher coverage, low copayment plans
with higher premiums.
 
     Under each of the Company's Plans, a premium is paid to the Company for the
type of coverage selected making the employee and each participating dependent a
member of the Plan. Premium payments are made by the employer or by the employee
(usually by payroll deduction) with respect to employer offered Plans or by the
member directly. Over half of the Company's revenues are derived from Plans in
which the member pays the entire premium. The remainder of the Plans are paid
either entirely by the employer or partially by the employer with the member
contributing the balance of the premium. Typically, the premiums charged are
fixed for a 12-month contract, except for certain multiple year contracts that
are subject to limitations on premium increases. Recently, the increase in the
dental component of the Consumer Price Index has averaged approximately 6% per
year. The Company estimates that its increases in premiums have averaged less
than 3.5% per year and that the premiums charged by the Company are typically
20% or more below premiums for comparable indemnity dental benefits.
Consequently, the Company believes that it is able to offer Plans that are not
only less expensive than the indemnity competition, but also have had lower
increases than most dental costs and indemnity premiums.
 
     Many of the Company's Plans permit each member to select his or her own
individual general dentist from the Company's dentist network at the time of
enrollment. The Company intends to incorporate this flexibility into all its
Plans. Each month, the Company pays a fixed payment, or capitation, to the
member's general dentist regardless of which services are rendered in the month.
In return for the capitation payment and the specified copayments, the general
dentist agrees to provide all covered services for the member.
 
     Although the Plans vary, typically routine preventive and diagnostic care
(exams, x-rays, sealants, teeth cleanings) is provided at no charge or at a
small copayment while basic care (including fillings and extractions) and
specialty care (root canal therapy and gum disease, or periodontal services) is
provided at stipulated copayments. More involved major care (such as crowns and
bridges) is also provided at copayments that are frequently lower than the
member's cost of coinsurance under a comparable indemnity insurance plan. The
Company believes that a specialty care referral program with specialist dentists
providing services at fixed copayments is necessary for the cost management of
dental care services. Orthodontic care is also available under many of the
Company's Plans.
 
                                       27
<PAGE>   29
 
  Dual Choice Plans
 
     The Company is able to offer employers Plans providing both managed dental
benefits and traditional indemnity insurance coverage, commonly referred to as
dual choice plans. Such Plans allow an employee to select the most suitable type
of coverage at the beginning of the contract year by offering each employee the
choice of a prepaid plan utilizing the Company's dentist network or traditional
indemnity insurance coverage utilizing any dentist but usually at higher
premiums and with lower coverage than the prepaid plan alternative. A dual
choice plan is particularly useful when some employees reside in areas where the
Company's dentist network is less developed or in states where the Company is
not yet licensed to offer managed dental benefits.
 
     The indemnity portion of the dual choice plans is made available either
through the Company's subsidiary that is licensed to offer dental indemnity
insurance in all states where the Company operates a prepaid dental plan or
through contractual arrangements with third party insurers. An employee who
selects the indemnity insurance option pays a portion of the charges for covered
services (or coinsurance) after satisfying any deductible. Although coinsurance
payments are typically higher than the copayments charged for the same services
under the other Company Plans, the employee may select any dentist for dental
services. In certain states, the Company has contracted with PPOs for discounted
fees for services covered under the Company's indemnity insurance.
 
     Currently, the Company offers its dual choice plans and its point of
service plan as an enhancement to the marketing of its core business of prepaid
dental benefits. As of June 30, 1996, the Company had approximately 76,000
individuals covered through its indemnity insurance subsidiary, excluding point
of service members who are considered prepaid members.
 
  Third-Party Plans
 
     The Company offers customized plans and services through contractual
arrangements with medical HMOs, including contracts under which the Company acts
as a dental benefits subcontractor to HMO's that have contracted with state
agencies to provide Medicare or Medicaid benefits. Under these arrangements, the
Company often provides only preventive and diagnostic dental benefits but may
also provide more comprehensive coverages, in each case either on a
"private-label" basis or directly through the Company's Plans. As of June 30,
1996, the Company had 15 such arrangements which accounted for approximately
6.3% of its managed dental benefits membership and approximately 2.3% of its
revenues. The Company believes its size and geographic scope give it a
competitive advantage in developing additional third-party medical HMO
relationships.
 
  Point of Service Plan
 
     The Company has developed a point of service plan ("POS") that provides
members of the Company's prepaid dental plans the option of receiving dental
services from dentists outside the Company's dentist network on an indemnity
basis providing less coverage. The POS Plan allows the member to select the
dentist of the member's choice each time services are obtained. Although the
Company charges higher premiums under the POS Plan, the Company has somewhat
greater risk exposure than under its managed dental benefit plans.
 
  Dental Referral Plan
 
     Through its pending acquisition of Association Dental Plan, Inc., the
Company plans to offer a referral plan. This plan will initially be delivered
through a network of approximately 9,400 providers in 36 states. The referral
plan contracts with the dental providers to provide dental services to referral
plan members at certain scheduled fee-for-service rates. Members of the referral
plan pay a fixed fee per month for the member's ability to access the Company's
referral plan network. The Company will bear no financial risk or responsibility
for dental services provided to members in conjunction with its referral
product.
 
                                       28
<PAGE>   30
 
DENTIST NETWORKS
 
     The Company designs its plans and capitation programs to create dentist
networks of general and specialist dentists that the Company believes provide
the quality of care and convenience needed to attract and retain members. The
Company's strategy is to be one of the three largest dentist networks in each of
its key markets. As of June 30, 1996, the Company had provider contracts with
approximately 3,000 general dentists. The Company also had contracts with
specialist dentists, representing the specialties of endodontics, oral surgery,
orthodontics, periodontics and pedodontics. Since specialist care is covered
under most of the Company's Plans, the Company has a specialist care referral
review program in order to manage the specialist care provided.
 
     The Company employs 32 provider relations representatives located in local
offices situated in its key markets who recruit general and specialty dentists,
determine their qualifications for participation in the Company's network,
provide administrative training to the dentist's office staff and assist the
dentists with respect to participation in the Company's network. Collectively,
the dental directors are responsible for establishing and monitoring the
Company's quality review efforts, including credentialing and re-credentialing
for network participation, review of specialty referrals and utilization review.
 
     Typically, the Company seeks established, private-practice dentists who
have capacity in their practice to see at least 200 of the Company's members as
new patients. Most general dentists and specialist dentists with whom the
Company contracts have small dental offices similar to those familiar to most
consumers. Both the dentist and the facility are reviewed in the Company's
credentialing process, which includes verification of licensure and malpractice
coverage, as well as a review of any actions that may have been taken by state
regulatory authorities. In addition to professional practice capabilities, the
Company also reviews the service amenities of the office, including available
parking, days and hours of operation, a patient recall system for routine,
preventive check-ups and radiographic and sterilization equipment and
procedures. Upon determining that a dentist meets the Company's requirements for
participation in the Company's dental network, the Company offers the dentist a
provider contract setting forth the capitation payments, copayments, limitations
and exclusions and other terms and conditions applicable to the specific Plans
in which such dentist will participate. Provider contracts are typically
non-exclusive and permit the Company or the dentist to terminate the contract
with 90 days prior written notice. The Company periodically reviews its general
and specialist dentists for continued compliance with Company requirements for
participation in the Company's dentist network.
 
     The Company believes that the advantages to a dentist who participates in a
managed dental benefits plan include: (i) increasing the size of the dentist's
practice as a result of selection of the dentist by plan members and referrals
from plan members; (ii) increasing practice profitability through utilization of
excess capacity to accept additional patients; (iii) generation of predictable
incremental cash flow from regular capitation payments; (iv) retention of
patients seeking managed dental plan participation; and (v) reduction of paper
work and collection risks associated with conventional fee-for-service
practices.
 
     The general and specialist dentists are independent from the Company,
providing service to members of the Company's Plans based upon dental practice
standards in the community and their contractual arrangements with the Company.
The Company requires that its network dentists maintain malpractice insurance
and satisfy quality service standards.

MARKETS AND OPERATIONS
 
     The Company currently is licensed to market its prepaid dental plans in 25
states, and its indemnity plan in 25 states. As of June 30, 1996, approximately
75.1% of all UDC prepaid plan members were located in four states, Arizona,
Texas, New Mexico and Colorado. The table below shows the approximate number of
managed benefits members, indemnity members, referral plan members and total
members of the Company as of June 30, 1996.

</TABLE>
 
     The acquisition of US Dental added approximately 163,000 members located in
four states where the Company already operated prepaid plans. The acquisition of
AHP added approximately 220,000 members, all of whom were located in Arizona.
The Pending Acquisitions are expected to add approximately 500,000 members in
the aggregate, of which approximately 350,000 members will be in four states
where the Company presently has no members. See "Pending and Recent
Acquisitions."
 
     The Company markets its plans to small, single-market employers and large,
multi-state employers, as well as to individuals. No single employer group
accounted for more than 2% of the Company's revenues for the six months ended
June 30, 1996.
 
     The Company maintains its regional customer service centers in Phoenix,
Arizona, San Diego, California, Denver, Colorado and Dallas, Texas. In addition,
the Company maintains 23 local offices with group sales and service
representatives and provider relations representatives in its key markets having
significant concentrations of members.
 
SALES AND MARKETING
 
     The Company markets its Plans primarily to employers through: (i) its
direct sales force of over 70 persons focusing on medium to large groups such as
multi-state employers and trade or professional organizations; and (ii) a
network of independent insurance brokers who market to smaller employers and
individuals. In addition, the Company markets to medical HMOs to offer the
Company's Plans as an additional benefit to HMO members. The Company believes
its multiple distribution channel approach is a competitive advantage that
provides the flexibility to meet the needs of the full spectrum of customers.
 
     The Company has focused the efforts of its direct sales representatives on
medium-to-large employers typically employing more than 250 employees and having
no relationship with an insurance broker. If an employer utilizes an insurance
broker, the Company generally sells through the broker to maintain its broker
relationships. The Company's direct sales representatives are compensated by a
combination of base salary and commissions based upon membership growth. The
Company has implemented a direct sales effort in all of its major markets.
 
     The Company also sells its Plans through independent insurance brokers who
typically have relationships with small and medium size employers. Approximately
two-thirds of the Company's membership is the result
 
                                       30
<PAGE>   32
 
of sales through brokers who receive commissions based on premiums received by
the Company from such sales.
 
     The Company has actively pursued alliances with HMOs to offer its Plans to
HMO members either on a private label basis or as a separate benefit and
currently has 15 such agreements in place. The Company believes that, as HMOs
seek to differentiate their services, many will consider contracting for dental
benefit plans and that the Company has a competitive advantage in arranging
alliances with HMOs as a result of the Company's experience, size and geographic
scope.
 
     Sales to employers, regardless of distribution channel, involve selling
both the employer and its employees. Typically, the employee has the opportunity
to select the Company's Plans during an annual open enrollment period.
Frequently, representatives of the Company have the opportunity to make
presentations directly to the employees, while in other cases the employer
distributes the Company's marketing materials that explain the features and
benefits of the Company's Plan. The Company stresses: (i) the quality and size
of its dentist networks; (ii) the comprehensiveness of its Plan, including
specialty care coverage; (iii) its integrated customer service approach in
responding to member inquiries or complaints, including requests to change
general dentists; and (iv) the value of the Plan in relation to Plan premiums
and copayments.
 
CUSTOMER SERVICE
 
     The Company employs 92 group sales and service representatives, 32 provider
relations representatives and 51 customer service representatives with primary
responsibility to service the needs of its groups and brokers, general and
specialist network dentists, and members, respectively. The Company's group
sales and service representatives and provider relations representatives are
based at the local market level, while the Company's customer service
representatives are located at four regional customer service centers in
Arizona, California, Colorado and Texas. Inquiries or complaints from members
are handled over the telephone via 800-telephone numbers by the regional
customer service representatives who provide consistent, responsive and
efficient member services. The Company believes this integrated approach enables
it to respond quickly and personally to group, broker and dentist issues where
direct interaction is critical.
 
MANAGEMENT INFORMATION SYSTEMS
 
     All administrative, accounting, finance and information services are
provided from the Company's administrative offices in Dallas, Texas. The Company
believes that, in the managed dental benefits industry, an advanced information
system can be a significant competitive advantage. Accordingly, in 1995, the
Company entered into a contract to acquire an advanced software program
specifically designed for the managed dental benefits industry and subsequently
has acquired the necessary hardware to fully utilize such software. The Company
believes its new information system will significantly enhance the Company's
capabilities to provide customer service, analyze provider utilization, create
opportunities to take advantage of market conditions and support new product
development.
 
     All of the Company's business is in the process of being converted to the
new information system. The conversion of the internally developed systems
formerly in use by IDH and AHP prior to their respective acquisitions by the
Company has been substantially completed. The Company's internally developed
system and the internally developed system used by US Dental at the time of the
US Dental acquisition are in the process of being converted. Until the
conversion is completed, the Company believes its system and the US Dental
system are adequate for the Company's current needs. The Company expects that
all of these systems will be fully integrated to the new system by the end of
1996. The information systems of the Pending Acquisitions will be converted to
the new system as rapidly as possible, although the timing for the completed
integration of such systems cannot currently be estimated.
 
     The Company has an administrative services agreement with R.E. Harrington,
Inc. ("Harrington") pursuant to which Harrington provides indemnity claim
administrative services to the Company. The Company pays Harrington 3.85% of all
claims paid by Harrington, which percentage may be reduced if Harrington does
not meet performance guarantees. The term of this agreement is from January 1,
1995 to December 31, 1996, but the Company may terminate the contract with
90-day advance written notice and the payment of a contractual penalty.

COMPETITION
 
     There are numerous competitors wherever the Company conducts business,
creating a highly competitive marketplace. The Company's competitors include:
(i) large insurance companies with the capability to offer both managed dental
benefits and traditional dental indemnity insurance; (ii) HMOs that also offer
dental benefits; (iii) self-funded employer programs; (iv) dental PPOs; (v)
discounted, fee-for-service membership plans; and (vi) other local or regional
companies offering prepaid dental plans.
 
     The Company believes the key factors in selecting a particular managed
dental benefits company include: (i) the comprehensiveness and range of prepaid
plans offered; (ii) the quality, accessibility and convenience of dentist
networks; (iii) the responsiveness of customer service; and (iv) the premium
charged. In all of the Company's markets, other prepaid dental plans and
insurance companies compete aggressively on all of these factors, particularly
in situations where the selection is through a competitive bidding process.
Certain markets also have intense price competition that could occur in all
markets in the future. In recent years, the Company has seen increasing
competition coming from all competitive sectors and the Company anticipates that
this trend will continue.
 
     Larger, national indemnity insurance companies that offer both prepaid and
indemnity dental coverage may have a competitive advantage over independent
dental plans due to availability of multiple product lines, established business
relationships, better name recognition and greater financial and information
systems resources. The Company believes that it can effectively compete with
insurance companies due to the specialized focus of its management team and
resources directed towards developing competitive dental benefits plans at
generally lower premiums.
 
     While some medical HMOs offer their own prepaid dental plans, others
contract with independent managed dental plans for those services. The Company
believes that it can compete with HMOs that offer dental benefits and pursue
opportunities to form alliances with HMOs to offer dental benefits to HMO
members. See "-- Sales and Marketing."
 
GOVERNMENT REGULATION
 
  General
 
     State insurance laws and other governmental regulations establish various
licensing, operational, financial and other requirements relating to the prepaid
dental plan business. State insurance departments and other regulatory agencies
are typically empowered to interpret such laws and promulgate regulations
applicable to the prepaid dental plan business. The laws and regulations
relating to the health care industry in general, and prepaid dental plans
specifically, are rapidly developing and have been the subject of numerous past
and present proposals which, if adopted, could adversely affect the Company's
business. Such proposals have included proposals that would require the Company
to admit "any willing provider" to its dental networks, create mandatory minimum
capitation payments to dental providers and specify minimum loss ratios or
mandate schedules of benefits. In addition, the Company's insurance company
subsidiary is subject to numerous laws and regulations applicable to insurance
companies generally. The Company is unable to predict the extent to which
changes to existing laws and regulations will be adopted or the effect that any
such changes may have on the Company's business.
 
     The Company's ability to conduct its business in additional states is
subject to regulatory approvals required in connection with either acquisitions
of existing prepaid dental plan businesses or the application of the Company to
conduct its existing business in additional states. Approvals to acquire another
licensed prepaid dental plan business often require six months or longer to
obtain while licenses and approvals necessary to commence operations of the
Company's existing business in an additional state can require two years or
longer to obtain. In addition, no assurance can be given that the Company's
applications for any such licenses or approvals will be granted, in which case
the Company's plans to expand in additional states would be adversely affected.
In circumstances where the Company is unable to obtain licenses to conduct its
business in a particular state or pending the grant of a license, the Company
would be required to conduct business through contractual arrangements with a
licensed insurance company or a licensed HMO, which arrange-
 
                                       32
<PAGE>   34
 
ments are typically less advantageous to the Company than its independent
offering of its prepaid dental plans. See "-- Business Strategy."
 
     In addition to regulatory approvals for acquisitions and additional
licenses, various regulatory approvals and filing requirements may apply to
ongoing aspects of the Company's business such as approvals for benefits plans
offered, premium rates and certain contractual relationships with HMOs and
insurance companies. If the Company fails to maintain compliance with all
material regulations, regulatory authorities are empowered to take certain
actions against the Company such as license revocations that could adversely
affect the Company's ability to conduct business.
 
  United Dental Care Insurance Company
 
     UDCIC is licensed to conduct business in 25 states. UDCIC is a traditional
indemnity insurance carrier and therefore assumes underwriting risk. Currently,
UDCIC provides the indemnity portion of some of the Company's dual choice plans.
UDCIC has not issued any other form of insurance, and its maximum coverage under
each dental insurance policy is generally $1,000.
 
     UDCIC is regulated by the Arizona Department of Insurance and the
departments of insurance of the other states in which UDCIC is licensed to
transact insurance business. The Company's ability to expand UDCIC's insurance
operations into states in which UDCIC is not currently licensed is dependent,
for the most part, on prior regulatory approval, which must be sought from the
department of insurance in each state in which the Company is applying. Such
reviews may take from six months to two years or more. Insurance companies are
heavily regulated and require significant cash deposits for capital and surplus.
The regulations of the various state insurance departments include specific
requirements with regard to such matters as minimum capital and surplus,
permitted investments, advertising, policy forms and claims processing
requirements. See "-- Legal Proceedings."
 
     In December 1992, the National Association of Insurance Commissioners
approved risk-based capital ("RBC") standards for life and/or health insurance
companies, as well as a Model Act (the "RBC Model Act") to apply to such
standards at the state level. The RBC Model Act requires an insurance company to
submit an annual RBC report which compares its total adjusted capital with its
risk-based capital as calculated by an RBC formula which takes into account the
risk characteristics of the company's investments and products. The RBC formula
includes capital requirements for four categories of risk: asset risk, insurance
risk, interest rate risk and business risk, with capital requirements increasing
for higher levels of risk. There are four levels of progressively more intense
regulatory action against insurance companies whose total adjusted capital does
not meet the RBC standards, starting with the company being required to submit a
plan to improve its capitalization and ending with the state insurance
department placing the company under regulatory control. The State of Arizona
adopted the RBC Model Act effective January 1, 1996. At December 31, 1995,
UDCIC's total adjusted capital was $6.7 million, or 299%, of the "company action
level" of the RBC standard of $2.2 million. If the capital and surplus of UDCIC
does not exceed the "company action level" at December 31, 1997, UDCIC would be
required to submit a business plan to the state regulators. The Company does not
believe that compliance with the RBC standards will adversely affect the
Company's business since the Company estimates that UDCIC will be able to
satisfy such standards without the need for significant capital contributions by
the Company. In addition, the Company does not consider that compliance with the
RBC standards will adversely affect the ability of the Company to meet its
anticipated operating cash requirements.
 
FACILITIES
 
     The Company leases approximately 26,634 square feet of office space for its
corporate offices in Dallas, Texas under a lease expiring in March 1997. In
addition, the Company leases an aggregate of approximately 55,363 square feet of
space for its other regional and local offices with lease terms expiring at
various times through August 2001.

EMPLOYEES
 
     At June 30, 1996, the Company employed approximately 296 employees, of
which 92 were sales personnel, 51 were customer service personnel, 32 were
provider relations personnel, seven were dental directors and 114 were
administrative personnel. The Company has no collective bargaining agreements
with any unions and believes that its overall relations with its employees are
good.
 
INSURANCE
 
     The Company carries general liability, comprehensive property damage,
workers' compensation and other insurance coverages that management considers
adequate for the protection of the Company's assets and operations. There can be
no assurance, however, that the coverage limits of such policies will be
adequate. A successful claim against the Company in excess of its insurance
coverage could have a material adverse effect on the Company.
 
LEGAL PROCEEDINGS
 
     On May 24, 1996, the Arizona Department of Insurance filed a Notice of
Administrative Hearing against the Company alleging that the Company consummated
its acquisition of AHP in January 1996 without complying with the requirements
of the Arizona Insurance Holding Company Act (the "Act"). AHP is licensed in
Arizona as a prepaid dental plan organization. The Company did not make a filing
under the Act in connection with the AHP acquisition because the Company's
interpretation is that the Act does not apply to AHP since AHP is not an
"insurer" as defined by and subject to the Act. The Notice seeks fines of up to
$50,000 for each violation against the Company and any officer or director of
the Company who knowingly violated the Act, and also seeks an Order directing
compliance with the Act in connection with the AHP acquisition. The Arizona
Department of Insurance has broad powers to seek other remedies, including
injunctive relief and license revocation. There can be no assurance as to what
relief may ultimately be sought or obtained by the Arizona Department of
Insurance. The Company has filed an answer denying the allegations. A final
determination against the Company could have a material adverse effect on the
Company.
 
     The Company is, and may be in the future, party to litigation arising in
the course of its business. The Company carries insurance protecting it against
liability arising out of the provision of dental care services by contracting
dentists, who are not employees or agents of the Company. Claims against the
Company arising out of the provision of dental care services by contracting
dentists historically have been rare, but there can be no assurance that the
Company will not become involved in such litigation or otherwise become subject
to claims relating to its contracting dentists in the future. While the Company
has no significant pending claims, there can be no assurance that the Company's
insurance coverage will be adequate to cover all liabilities arising out of such
claims or that any such claims will be covered by the Company's insurance. Any
material claim which is not covered by insurance may have an adverse effect on
the Company's business. Claims against the Company, regardless of their merit or
outcome, may also have an adverse effect on the Company's reputation and
business.

                        PENDING AND RECENT ACQUISITIONS
 
PENDING ACQUISITIONS
 
     The Company has recently entered into agreements to acquire five managed
dental benefits companies operating prepaid dental plans in New Jersey, Florida,
Oklahoma, Missouri, Kansas and Michigan having approximately 440,000 members in
the aggregate at June 30, 1996. In addition, the Company has recently entered
into an agreement to acquire a company that operates a multi-state dental
referral plan having approximately 60,000 members at June 30, 1996. Upon
completion of the acquisitions, the Company will obtain licenses to operate
prepaid dental plans in four additional states and a license to operate an
indemnity plan in one additional state.
 
  OraCare Transaction
 
     On September 5, 1996, the Company entered into agreements to acquire
OraCare DPO ("OraCare"), a New Jersey prepaid dental plan having approximately
150,000 members at June 30, 1996, and to acquire a management company affiliated
with OraCare. Approximately 75.6% of OraCare's members are Medicaid members of
medical HMOs that contract with OraCare to provide the dental benefits under
their plans. Members of one medical HMO represent approximately 34.4% of
OraCare's total membership. In addition, as a part of the transaction, the
Company agreed to cause one of its affiliates to acquire a dental professional
association owned by the majority stockholder of OraCare. The affiliated
management company provides management services to both the prepaid dental plan
and the professional association which, as of June 30, 1996, operated eight
dental clinics servicing both members of the OraCare prepaid dental plan and
other third-party prepaid and fee-for-service patients.
 
     The OraCare entities had combined revenues of $9.2 million and $7.6 million
for the years ended December 31, 1995 and 1994, respectively, and $6.7 million
for the six months ended June 30, 1996. The consideration to be paid by the
Company in connection with the OraCare transaction is $30.5 million plus certain
contingent payments up to a maximum aggregate amount of $6.0 million based on
the financial performance of the Company in the States of New Jersey and
Pennsylvania in 1997 and 1998. The Company presently anticipates that
approximately $30.4 million of the initial consideration in the OraCare
transaction will be allocated to goodwill for financial statement purposes. See
"-- Acquisition Accounting Principles," the OraCare Combined Financial
Statements and the Notes thereto and the Unaudited Pro Forma Condensed Combined
Financial Statements.
 
     In connection with the OraCare transaction, the Company will enter into
employment agreements with two former OraCare stockholders as operating officers
of the OraCare management company and two former stockholders as dental
directors and dental providers of the professional association. In addition, the
OraCare management company will enter into a long-term management contract
pursuant to which it will furnish the facilities and equipment and certain
management services to the OraCare professional association relating to the
operation of its dental clinics. The capital stock of the OraCare professional
association will be acquired by a licensed New Jersey dentist designated by the
Company because of New Jersey regulations prohibiting the corporate practice of
dentistry. The OraCare transaction is subject to the receipt of New Jersey
regulatory approvals.
 
  UICI Transactions
 
     On September 10, 1996, the Company entered into definitive agreements to
acquire three companies, two of which are wholly owned by UICI, formerly known
as United Insurance Companies, Inc., and one of which is majority owned by UICI.
The companies that will be acquired are: (i) United Dental Care, Inc.
("United"), which, through an indemnity insurance subsidiary, operates a prepaid
dental plan in Oklahoma having approximately 90,000 members at June 30, 1996;
(ii) International Dental Plan, Inc. ("IDP"), which operates a prepaid dental
plan in Florida having approximately 100,000 members at June 30, 1996; and (iii)
Association Dental Plan, Inc. ("ADP"), which operates a multi-state dental
referral plan having approximately 60,000 members at June 30, 1996.
 
                                       35
<PAGE>   37
 
     The consideration to be paid by the Company in connection with the United
transaction is approximately $5.8 million (subject to adjustment based on the
net worth of United at the time of closing less $750,000, which at June 30, 1996
would have resulted in additional consideration of approximately $1.6 million).
In connection with the United transaction, the Company will enter into four-year
employment agreements with two employees of United. The consideration to be paid
by the Company in the IDP transaction is $4.5 million and the consideration to
be paid in the ADP transaction is $2.5 million. In addition, in connection with
the ADP transaction, a note owed by ADP to UICI having a balance of
approximately $770,000 will be repaid in full.
 
     United, IDP and AHP had combined revenues of approximately $16.6 million
for the year ended December 31, 1995 and $8.9 million for the six months ended
June 30, 1996. The Company presently anticipates that approximately $10.4
million will be allocated to goodwill for financial statement purposes in
connection with these transactions. See "-- Acquisition Accounting Principles,"
the UICI Dental Companies Combined Financial Statements and the Notes thereto
and the Unaudited Pro Forma Condensed Combined Financial Statements.
 
     The United transaction is subject to receipt of Oklahoma regulatory
approval. The United and ADP transactions are conditioned upon the simultaneous
closing of each transaction. The IDP transaction is subject to the receipt of
Florida regulatory approval. The United and ADP transactions are also subject to
the Company and two marketing entities affiliated with UICI having approximately
5,000 dedicated agents entering into a marketing agreement pursuant to which
such agents will market the dental benefit products of the Company.
 
  Kansas City Dental Care Transaction
 
     On September 11, 1996, the Company entered into an agreement to acquire
Kansas City Dental Care, Inc. ("KCDC"), which operates prepaid dental plans in
Missouri and Kansas having approximately 90,000 members in the aggregate as of
June 30, 1996. KCDC had revenues of approximately $8.4 million for the year
ended December 31, 1995 and approximately $4.8 million for the six months ended
June 30, 1996. The consideration to be paid by the Company in connection with
the KCDC transaction is $12.5 million plus a contingent payment up to a maximum
of $2.0 million based on the financial performance of the Company operations in
the states of Missouri and Kansas in the second year after completion of the
acquisition. The Company presently contemplates that approximately $12.4 million
of the consideration to be paid in the KCDC transaction will be allocated to
goodwill for financial statement purposes. In connection with the KCDC
transaction, the Company will enter into three-year employment agreements with
two management officers of KCDC, one of whom is a stockholder and officer of
KCDC and the other of whom is the current chief executive officer (and stock
option holder) of KCDC. The KCDC transaction is subject to the receipt of
Missouri and Kansas regulatory approvals. The Company currently operates prepaid
dental plans in both states. See the Kansas City Dental Care Financial
Statements and the Notes thereto and "Unaudited Pro Forma Condensed Combined
Financial Statements."
 
  Independent Dental Plan Transaction
 
     On June 28, 1996, the Company entered into an agreement to acquire
Independent Dental Plan, Inc. ("Independent"), which operates a prepaid dental
plan in Michigan having approximately 10,000 members at June 30, 1996.
Independent had revenues of approximately $1.7 million for the year ended
December 31, 1995 and $0.9 million for the six months ended June 30, 1996. The
consideration to be paid by the Company in connection with the Independent
transaction is approximately $1.2 million. In addition, in connection with the
Independent transaction, the Company will enter into employment agreements with
two of the operating officers of Independent.
 
     The Company intends to use the net proceeds of this offering to finance the
Pending Acquisitions, most of which are anticipated to be completed following
completion of this offering. However, none of the Pending Acquisitions are
subject to completion of this offering, and this offering is not subject to
completion of any of the Pending Acquisitions. The Company intends to obtain a
commitment for a $35 million line of credit with
 
                                       36
<PAGE>   38
 
an unaffiliated bank to finance certain of the Pending Acquisitions if they are
consummated prior to completion of this offering. The Company believes based on
discussions with such bank that it will be able to obtain such line of credit.
The Company also believes that it will be able to increase such line of credit
to $50 million if necessary to finance, together with available cash of the
Company, all the Pending Acquisitions if they are consummated prior to
completion of this offering. See "Management's Discussion And Analysis Of
Financial Condition and Results Of Operations -- Credit Facilities."
 
     Except as otherwise noted in this Prospectus, all information in this
Prospectus regarding the Company and its subsidiaries excludes information
relating to the Pending Acquisitions.
 
RECENT ACQUISITIONS
 
  US Dental Transaction
 
     Effective November 1, 1995, the Company acquired U.S. Dental Management,
Inc. ("US Dental"), which operated prepaid dental plans in Arizona, New Mexico,
Nebraska and Colorado and administered a prepaid dental plan owned by a third
party in Nevada. The US Dental plans had approximately 163,000 members at the
time of the acquisition. US Dental had revenues of approximately $13.3 million
and $13.0 million for the years ended December 31, 1995 and 1994, respectively.
The consideration paid by the Company in the US Dental acquisition was
approximately $12.6 million, which included the present value of amounts payable
under 50-month consulting agreements and 36-month non-competition agreements
with the two former stockholders of US Dental.
 
     The consideration paid in the US Dental acquisition was allocated for
financial statement purposes in the amounts of approximately $11.7 million to
goodwill, approximately $0.2 million to the non-competition and consulting
agreements and the balance to tangible assets. See "-- Acquisition Accounting
Principles."
 
  AHP Transaction
 
     Effective February 1, 1996, the Company acquired Associated Health Plans,
Inc. ("AHP"), which operated prepaid dental plans in Arizona having
approximately 220,000 members at the time of the acquisition. AHP had revenues
of approximately $14.2 million and $12.6 million for the years ended December
31, 1995 and 1994, respectively. The consideration paid by the Company in the
AHP transaction was approximately $15.0 million, which includes the present
value of amounts payable under 36-month non-competition agreements with four
former stockholders of AHP. The consideration paid in the AHP transaction was
allocated for financial statement purposes in amounts of approximately $14.1
million to goodwill, approximately $0.6 million to the non-competition
agreements and the balance to tangible assets. In making such allocation, the
Company applied the same accounting principles that it applied in connection
with the US Dental acquisition. See "-- Acquisition Accounting Principles."
 
ACQUISITION ACCOUNTING PRINCIPLES
 
     A substantial majority of the consideration paid by the Company in the US
Dental and AHP acquisitions was allocated to goodwill for financial statement
purposes. Goodwill relates to items traditionally associated with going concern
values such as the reputation of an acquired entity in its markets, name
recognition, the ability to maintain and further develop systems and market
position in geographic areas in which the Company previously did not have a
market position. The allocations made in the US Dental and AHP acquisitions were
not based on third-party appraisals. The Company relied on its own expertise and
experience in the industry in making the valuation for such allocation. Other
than the amounts allocated to the non-competition and consulting agreements, the
Company did not allocate any portion of the consideration to other intangibles
such as dentist networks and subscriber contracts. The amounts allocated as the
values of the non-competition and consulting agreements were significantly below
the contractual payments due under such agreements based on an estimate by the
Company of the value of the benefits expected under such agreements. See the
Company's Consolidated Financial Statements and the Notes thereto, the US Dental
Financial Statements and the Notes thereto, the AHP Combined Financial
Statements and the Notes thereto and the Unaudited Pro Forma Condensed
Consolidated Financial Statements.
 
                                       37
<PAGE>   39
 
     The Company did not allocate any portion of the US Dental or AHP
consideration to dentist networks because the dentist provider contracts were
non-exclusive and could be terminated on limited notice. The Company believes
that the expense attributable to recruiting new dentists does not constitute a
material portion of the Company's expenses incurred with respect to its ongoing
activities relating to credentialing dentists and maintaining its dental
provider relationships. The Company did not allocate any portion of the US
Dental or AHP consideration to subscriber contracts because the employer group
agreements generally had terms of less than one year. Additionally, individual
subscribers could terminate participation in the plan periodically during the
term of the employer group agreement, or at any time, if they cease to be
employed by the employer. The cost relating to recruiting, credentialing and
maintaining dentist networks and to sales and to account maintenance efforts are
expensed by the Company as incurred.
 
     The Company intends to apply the same accounting principles it applied in
connection with the US Dental and AHP acquisitions in allocating for financial
statement purposes the consideration to be paid in connection with the Pending
Acquisitions.

STOCK OPTION PLANS
 
  1989 Stock Option Plan
 
     The Company has a 1989 Key Employee Stock Option Plan (the "1989 Stock
Option Plan") that was adopted in April 1989. The 1989 Stock Option Plan
provides that a total of 724,000 shares of Common Stock of the Company may be

The Board of Directors has terminated the 1989 Stock Option Plan for the
purposes of any additional stock option grants thereunder.
 
  1995 Stock Option Plan
 
     The Company has a 1995 Stock Option Plan (the "1995 Stock Option Plan")
that was adopted by the Company's Board of Directors in April 1995 and approved
by the stockholders of the Company in September 1995. The 1995 Stock Option Plan
provides that a total of 800,000 shares of Common Stock of the Company may be

Common Stock to certain qualifying non-employee directors who were either
serving on the Board of Directors of the Company when the 1995 Stock Option Plan

Directors in the future to the extent that options are available under the 1995
Stock Option Plan. At June 30, 1996, options for 405,000 shares had been granted
under the 1995 Stock Option Plan.

Plan"). The 401(k) Plan is an individual account, defined contribution plan
which provides for deferred compensation as described in Section 401(k) of the
Internal Revenue Code of 1986. The 401(k) Plan is subject to the principal
protective provisions of Titles I and II of the Employee Retirement Income
Security Act of 1974.
 
EMPLOYMENT AGREEMENTS
 
     The Company has entered into an employment agreement with William H. Wilcox
pursuant to which he is employed as the President and Chief Executive Officer of
the Company at a base salary of $300,000 per year. The employment agreement has
a term until May 31, 1999 but may be terminated by either party upon 60 days
prior notice. Termination by the Company requires the approval of 75% of the
members of the Board of Directors. In the event of termination without cause,
the Company is required to pay a severance payment to Mr. Wilcox in an amount
equal to the amount of his base salary for the lesser of 24 months or the then
remaining term of the employment agreement, plus a bonus equal to the average of
the annual bonuses paid to Mr. Wilcox in the preceding two calendar years. In
addition, in such event, all stock options then held by Mr. Wilcox become fully
vested and exercisable within 90 days after the date of termination, although,
under certain conditions, the Board may continue the exercisability of such
options as originally scheduled (but without any vesting conditions other than
the passage of time). In the event Mr. Wilcox cannot obtain third-party
financing to exercise the options, the Company is obligated to make a one-year
loan to Mr. Wilcox in an amount necessary to exercise the options. In the event
a change of control of the Company occurs, Mr. Wilcox may resign with good
reason if there is a material diminution of his responsibilities, position or
authority, or the Company fails to perform its obligations under the agreement
and, in such event, all stock options held by Mr. Wilcox will become fully
vested and exercisable for a period of 90 days but no severance payments will be
 
                                       43
<PAGE>   45
 
due. The employment agreement contains non-competition provisions that survive
for the greater of one year or the period of time severance payments are being
made or stock options remain exercisable or a loan from the Company to Mr.
Wilcox is outstanding. In connection with his employment, Mr. Wilcox was also
granted stock options for 300,000 shares of Common Stock at an exercise price of
$33.38 per share.
 
     The Company has entered into an employment agreement with Mark E. Pape
pursuant to which he is employed as the Senior Vice President and Chief
Financial Officer of the Company. The employment agreement is on substantially
the same terms as the employment agreement with Mr. Wilcox except the agreement
has a term until May 31, 1998, the base salary for Mr. Pape is $165,000, the
severance payment is based on the lesser of 12 months of base salary or the base
salary payable over the remaining term of the agreement and only 50% of the
unvested stock options held by Mr. Pape are accelerated in the event of
termination without cause by the Company or resignation for good reason by Mr.
Pape after a change of control.
 
     The Company has entered into an employment agreement with Peter R. Barnett
pursuant to which he is employed as a Senior Vice President and Chief Operating
Officer of the Company. The employment agreement has identical terms, including
base salary, as the employment agreement with Mr. Pape.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Executive officer compensation decisions are made by the Compensation
Committee of the Board of Directors of the Company. Members of the Compensation
Committee currently are Messrs. Anderson and Longfield. Neither of these
individuals were at any time during the year ended December 31, 1995, or at any
time prior thereto, an officer or employee of the Company or any of its
subsidiaries. Upon completion of the offering, executive officer compensation
decisions will continue to be made by the Compensation Committee. During 1995,
no executive officer of the Company served as a director or as a member of the
compensation committee of any entity in which an executive officer of such
entity served as a director of the Company or as a member of the Company's
Compensation Committee. See "Principal Stockholders."
 
DIRECTOR COMPENSATION
 
     Directors do not receive compensation for service on the Board of Directors
or any committee thereof but are reimbursed for their out-of-pocket expenses
incurred in attending meetings of the Board of Directors and committees.
Qualifying directors who are not employees of the Company receive an automatic
one-time grant of options for 16,000 shares of Common Stock of the Company under
the 1995 Stock Option Plan. See "-- 1995 Stock Option Plan."
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Under Section 145 of the Delaware General Corporation Law ("Delaware Law"),
the Company has broad powers to indemnify its directors and officers against
liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Company's Bylaws provide that the Company shall indemnify
its directors and officers to the full extent permitted by law. The Bylaws also
provide that rights conferred thereunder shall not be deemed to be exclusive of
any other right such persons may have or acquire under any statute, the
Certificate of Incorporation, the Bylaws, agreement, vote of stockholders or
disinterested directors, or otherwise.
 
     The Certificate of Incorporation provides that, pursuant to Delaware Law,
the Company's directors shall not be liable for monetary damages for breach of
the directors' fiduciary duty of care to the Company and its stockholders. This
provision in the Certificate of Incorporation does not eliminate the duty of
care, and in appropriate circumstances equitable remedies such as injunctive or
other forms of non-monetary relief will remain available under Delaware Law. In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to the Company or its stockholders, for acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, for actions leading to improper personal benefit to the
director, and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Delaware Law. The provision also does not
effect a director's responsibilities under any other law, such as the Federal
securities laws or state or Federal environmental laws.

                              CERTAIN TRANSACTIONS
 
     On September 16, 1994, the Company acquired all the issued and outstanding
capital stock of International Dental Health, Inc., a dental benefits company
("IDH"), for a total purchase price of approximately $14.3 million. Mr. Robert
J. Nettinga, a director of the Company, was the president of IDH. The Adaven
Group Limited Partnership was the principal stockholder of IDH and received
approximately $7.5 million in payment for its IDH shares in the transaction. Mr.
Nettinga is the president and principal stockholder of the corporation that is
the general partner of The Adaven Group Limited Partnership. In connection with
such transaction, IDH also paid an outstanding promissory note to Mr. Nettinga
in the amount of $183,770.
 
     The Company also entered into a non-competition agreement with Robert J.
Nettinga and The Adaven Group Limited Partnership and a consulting agreement
with The Adaven Group Limited Partnership. Under the non-competition agreement,
the Company was obligated to pay, in six annual installments commencing in 1994,
approximately $3.3 million in the aggregate. Under the consulting agreement, the
Company was obligated to pay, in six annual installments commencing in 1994,
approximately $1.2 million in the aggregate. The Company has the right to prepay
such installments on a discounted present value basis using a discount rate of
5%. The obligations of the Company under the non-competition agreement and the
consulting agreement are secured by a letter of credit in the original amount of
approximately $4.0 million which amount declines annually after the payment
dates of the annual installments under such agreements.
 
     In the IDH transaction, On-Line, Inc., an assignee of Paul C. Nettinga, the
brother of Robert J. Nettinga, received approximately $1.8 million in payment
for IDH shares. The Company also entered into a non-competition agreement with
Omega Marine Development, Inc. and Paul C. Nettinga under which the Company was
obligated to pay, in six annual installments commencing in 1994, approximately
$0.6 million in the aggregate and a consulting agreement with Omega Marine
Development, Inc. under which the Company was obligated to pay, in six annual
installments commencing in 1994, approximately $0.3 million in the aggregate.
Paul C. Nettinga is the president of Omega Marine Development, Inc. The terms of
the non-competition agreement and the consulting agreement for Paul C. Nettinga
and Omega Marine Development, Inc. are substantially the same as the agreements
with Robert J. Nettinga and The Adaven Group Limited Partnership. IDH also paid
an outstanding promissory note to Paul C. Nettinga in the amount of
approximately $0.3 million. The obligations of the Company under the
non-competition agreement and the consulting agreement are secured by a letter
of credit in the original amount of approximately $0.8 million which amount
declines annually after the payment dates of the annual installments under such
agreements.
 
     The non-competition agreements restrict the parties thereto from competing,
directly or indirectly, with the business of the Company in the continental
United States and from soliciting the employment of any employee of the Company
until September 16, 2000. Under the consulting agreements, the parties thereto
agreed to provide to the Company services as an independent consultant and
adviser with respect to such business and financial matters as may be reasonably
requested by the Company from time to time for a period of six years. The party
providing such consulting services may not be required to render such services
outside of the state of residence of such party without the consent of such

     The Company, certain stockholders of the Company and Robert J. Nettinga
entered into a Stockholders Agreement on September 16, 1994 pursuant to which
such stockholders agreed to vote shares of Common Stock of the Company owned by
them for the election of Robert J. Nettinga as a director of the Company until
the earlier of the expiration of four years from the date of such agreement or
the date when all monetary obligations of the Company have been paid under the
non-competition agreement and the consulting agreement with Robert J. Nettinga.
See "Management."

40,000 warrants was $2.00 per warrant, and the warrants have an exercise price
of $6.00 per share of Common Stock.

<PAGE>   48
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 15,000,000 shares
of Common Stock, $.10 par value per share, and 500,000 shares of Preferred
Stock, $.10 par value per share.
 
CAPITAL STOCK
 
     At September 13, 1996, there were 6,908,416 shares of Common Stock
outstanding, and such shares were held by approximately 93 stockholders of
record. Each holder of Common Stock is entitled to one vote for each share held.
The shares of Common Stock do not have cumulative voting rights. Following this
offering, the holders of Common Stock, voting as a single class, will be
entitled to elect all of the directors of the Company. Matters submitted for
stockholder approval generally require a majority vote.
 
     Holders of Common Stock are entitled to receive ratably such dividends as
may be declared by the Board of Directors out of funds legally available
therefor. In the event of a liquidation, dissolution or winding up of the
Company, holders of Common Stock will be entitled to share ratably in the
Company's assets remaining after the payment of liabilities and the satisfaction
of any liquidation preference granted to the holders of any outstanding shares
of Preferred Stock. Holders of Common Stock have no preemptive or other
subscription rights. The shares of Common Stock are not convertible into any
other security. The outstanding shares of Common Stock are, and the shares being
offered hereby will be, upon issuance and sale, fully paid and nonassessable.
See "Dividend Policy."
 
     At June 30, 1996, there were no shares of Preferred Stock outstanding. The
Company is authorized to issue up to 500,000 shares of undesignated Preferred
Stock.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
     Upon completion of the offering, there will be 6,091,584 authorized but
unissued shares of Common Stock and 500,000 authorized but unissued shares of
Preferred Stock, all of which can be issued without stockholder approval. These
additional shares may be utilized for a variety of corporate purposes, including
future public offerings to raise additional capital or to facilitate corporate
acquisitions. The Company does not currently have any plans to issue additional
shares of Common Stock or Preferred Stock (other than shares of Common Stock
which may be issued upon the exercise of options or warrants which have been
granted or which may be granted in the future by the Company).
 
     One of the effects of the existence of unissued and unreserved Common Stock
and Preferred Stock of the Company may be to enable the Board of Directors to
issue shares to persons friendly to current management which could render more
difficult or discourage an attempt to obtain control of the Company by means of
a merger, tender offer, proxy contest or otherwise, and thereby protect the
continuity of the Company's management and possibly deprive the stockholders of
opportunities to sell their shares of Common Stock at prices higher than
prevailing market prices. Such additional shares could also be used to dilute
the stock ownership of persons seeking to obtain control of the Company.
 
     The Board of Directors is authorized, without any further action by the
stockholders, to determine the rights, preferences, privileges and restrictions
of the unissued Preferred Stock. One purpose of authorizing the Board of
Directors to determine such rights and preferences is to eliminate delays
associated with a stockholder vote on specific issuances. The Board of Directors
may issue Preferred Stock with voting and conversion rights which could
adversely affect the voting power of the holders of Common Stock and which
could, among other things, have the effect of delaying, deferring or preventing
a change in control of the Company.
 
CERTAIN PROVISIONS OF CERTIFICATE OF INCORPORATION AND BYLAWS
 
     The Delaware General Corporation Law provides that Delaware corporations
may amend their certificates of incorporation to relieve directors of monetary
liability for breach of their fiduciary duty including acts constituting gross
negligence, except under certain circumstances (including breach of the
director's duty of loyalty, acts or omissions not in good faith or involving
intentional misconduct and a knowing violation of law
 
                                       47
<PAGE>   49
 
or any transaction from which the director derived improper personal benefit).
The Company's certificate of incorporation provides that the Company's directors
are not liable to the Company or its stockholders for monetary damages for
breach of their fiduciary duties, subject to the exceptions specified by
Delaware law.
 
     Under Delaware law, the exclusive power to adopt, amend and repeal bylaws
is conferred solely on the stockholders unless the corporation's certificate of
incorporation also confers this power upon its board of directors. Under the
Company's Certificate of Incorporation, the Board of Directors has been granted
this power. The Company's Bylaws also provide that the number of directors shall
be as from time to time fixed by resolution of the Board. These provisions, in
addition to the existence of authorized but unissued capital stock, may have the
effect, either alone or in combination with each other, of making more difficult
or discouraging an acquisition of the Company deemed undesirable by the Board of
Directors.
 
BUSINESS COMBINATIONS
 
     Delaware law prohibits Delaware corporations from engaging in a wide range
of specified transactions with any interested stockholder, defined to include,
among others, any person or entity who in the last three years obtained 15% or
more of any class or series of stock entitled to vote generally in the election
of directors, unless, among other exceptions, the transaction is approved by (i)
the board of directors prior to the date the interested stockholder obtained
such status or (ii) the holders of two-thirds of the outstanding shares of each
class or series of stock entitled to vote generally in the election of
directors, not including those shares owned by the interested stockholder. The
provisions of this statute apply to the Company.
 
     The effect of this statute may be to deter unfriendly offers or other
efforts to obtain control of the Company that are not approved by the Board of
Directors and thereby protect the continuity of the Company's management and
possibly deprive the stockholders of opportunities to sell their shares of
Common Stock at prices higher than prevailing market prices. Such statute may
also tend to induce any persons seeking control of the Company or a business
combination with the Company to negotiate on terms acceptable to the then
elected Board of Directors.
 
REGULATORY REQUIREMENTS
 
     State insurance laws applicable to the Company typically require regulatory
approval for any proposed change of control of the Company. Generally, a change
of control would be deemed to result if anyone acquired 10% or more of the
outstanding voting stock of the Company, although regulatory authorities
generally have discretion to determine whether a change of control in a
particular case would occur whether or not 10% of the voting stock of the
Company is acquired. Therefore, no one can acquire beneficial ownership of 10%
or more of the outstanding Common Stock of the Company, whether pursuant to this
offering, open market purchases or otherwise, without obtaining prior regulatory
approval. Such regulatory approval requirement could also apply to the
solicitation of proxies to vote 10% or more of the outstanding Common Stock and
therefore could impair the ability of a stockholder to conduct a proxy contest.
The Company could seek a regulatory hearing with respect to any stockholder
proposal to acquire beneficial ownership or proxies for 10% or more of the
Company's Common Stock, and any stockholder that fails to obtain regulatory
approval in such circumstances may be subject to regulatory sanctions including
the possibility of a divestiture order. In addition, failure to comply with such
regulatory requirements could result in adverse consequences to the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Company's Common Stock is First
Union National Bank of North Carolina.

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will purchase all shares of the Common Stock offered hereby if any
of such shares are purchased.
 
     The Company has been advised by the Representatives of the Underwriters
that the Underwriters propose to offer the shares of Common Stock to the public
at the public offering price set forth on the cover page of this Prospectus and
to certain dealers at such price less a concession not in excess of $
per share. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of $          per share to certain other dealers. After
the public offering, the offering price and other selling terms may be changed
by the Representatives of the Underwriters.
 
     The Company and James B. Kingston, a director of the Company, have granted
the Underwriters an option, exercisable not later than 30 days after the date of
this Prospectus, to purchase up to 300,000 additional shares of Common Stock in
the aggregate at the public offering price less the underwriting discounts and
commissions set forth on the cover page of this Prospectus. To the extent that
the Underwriters exercise such option, each of the Underwriters will have a firm
commitment to purchase approximately the same percentage thereof that the number
of shares of Common Stock to be purchased by it shown in the above table bears
to 2,000,000, and the Company and Mr. Kingston will be obligated, pursuant to
the option, to sell 225,000 and 75,000 shares, respectively, to the
Underwriters. To the extent that the Underwriters exercise such option, the
first 75,000 shares would be purchased from Mr. Kingston. The Underwriters may
exercise such option only to cover over-allotments made in connection with the
sale of the Common Stock offered hereby. If purchased, the Underwriters will
offer such additional shares on the same terms as those on which the 2,000,000
shares are being offered.
 
     The Company and the selling stockholder have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act.
 
     The Company, its directors, executive officers and certain stockholders
have agreed that, subject to certain limited exceptions, they will not, for a
period of 90 days after the date of this Prospectus, sell, offer to sell,
contract to sell or otherwise dispose of any shares of Common Stock or any other
securities of the Company without the prior written consent of the
Representatives of the Underwriters, except that the Company may, without such
consent, issue shares of Common Stock under the 1989 Stock Option Plan and grant
options and issue shares of Common Stock under the 1995 Stock Option Plan. In
addition, the Company may issue shares of Common Stock in connection with any
acquisition of another company if the terms of such issuance provide that such
Common Stock shall not be sold prior to the expiration of the 90 day period
referenced in the preceding sentence.
 
     In connection with this offering, the Underwriters and selling group
members, if any, or their respective affiliates who are qualified registered
market makers on the Nasdaq National Market, may engage in passive market making
transactions in the Common Stock on the Nasdaq National Market during the two

day period prior to the commencement of the offers or sales of the Common Stock,
in accordance with Rule 10b-6A under the Exchange Act. Passive market making
consists of displaying bids on the Nasdaq National Market limited by the bid
prices of market makers not connected with this offering and purchases limited
by such prices and effected in response to order flow. Net purchases by a
passive market maker on each day are generally limited in amount to 30% of the
passive market maker's average daily trading volume in the Common Stock during
the two full consecutive calendar months immediately prior to the filing with
the Commission of the Registration Statement and must be discontinued when such
limit is reached. Passive market making may stabilize the market price of the
Common Stock at a level above that which might otherwise prevail and, if
commenced, may be discontinued at any time.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
  United Dental Care, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of changes in stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of United Dental Care, Inc. and its subsidiaries at December 31, 1994
and 1995, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.
 
     As discussed in Notes 1 and 7, the Company adopted Statement of Financial
Account Standards No. 109, "Accounting for Income Taxes," effective January 1,
1993.

                   UNITED DENTAL CARE, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     BASIS OF PRESENTATION: The consolidated financial statements include the
accounts of United Dental Care, Inc., and its subsidiaries (the "Company") for
all periods presented. All significant intercompany accounts and transactions
have been eliminated in consolidation. The Company, through its subsidiaries,
contracts with independent practitioners to provide dental services to members
in 19 states in the form of prepaid dental health contracts and/or indemnity
dental insurance.
 
     REVENUE AND EXPENSE RECOGNITION: Premium revenue is recorded in the month
for which the member is entitled to service. Unearned premiums are reflected as
current liabilities and consist of amounts billed in the current period for
services to be rendered in a subsequent period. Included in unearned premiums
are deposits which will be applied against future months' services. Under
prepaid dental health contracts, the Company contracts with dentists for a set
per-member, per-month capitation fee to provide dental care for its members.
Specialty services not covered by capitation fees are recorded as incurred.
 
     INTANGIBLE ASSETS: Goodwill resulting from acquisitions (see Note 2) is
being amortized on a straight-line basis over forty years. If facts and
circumstances were to indicate the carrying amount of goodwill is impaired, the
carrying amount would be reduced to an amount representing the undiscounted
future cash flows to be generated by the operation. Also included in intangible
assets are noncompetition and consulting agreements (a) related to the IDH
acquisition and valued at $400,000 at acquisition and (b) related to the US
Dental acquisition and valued at $175,000 at acquisition all of which are being
amortized on a straight-line basis over the three to six year terms of such
agreements. Accumulated amortization related to these agreements at December 31,
1994 and 1995, and June 30, 1996 was $23,000, $110,000, and $259,000,
respectively.
 
     In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 ("FAS-121") "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of,"
which becomes effective for fiscal years beginning after December 15, 1995.
FAS-121 establishes standards for determining when impairment losses on
long-lived assets have occurred and how impairment losses should be measured.
The Company adopted FAS-121 effective December 31, 1995. The financial statement
impact of adopting FAS-121 was not material.
 
     PRE-OPERATIONAL COSTS: Organizational costs, costs associated with the
establishment of the provider network, and pre-operational costs are capitalized
and amortized over periods not exceeding 30 months. Pre-operational costs
include office rent, salaries, site selection costs, licensing and legal fees,
and other costs directly related to commencing business in a new state.
 
     FURNITURE AND EQUIPMENT: Furniture and equipment are recorded at cost.
Depreciation is calculated using the straight-line method over a period of three
to five years based on the estimated useful life of the related asset.
 
     CLAIMS RESERVE: The reserve for costs expected to be incurred for services
approved during the year as well as costs incurred but not reported are
actuarial estimates based on the Company's historical claims data.
 
     RECLASSIFICATIONS: Certain reclassifications have been made to the 1993 and
1994 consolidated financial statements to conform to the classifications used
for 1994 and 1995, respectively.
 
     CASH AND CASH EQUIVALENTS: For purposes of reporting cash flows, cash and
cash equivalents include cash on hand, amounts due from banks, money market
investment accounts held by brokers which are readily convertible to cash and
certificates of deposit with original maturities of less than 90 days. See Note
2.
 
     INCOME TAXES: Effective January 1, 1993, the Company prospectively adopted
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (FAS-109), which requires the asset and liability method of accounting
for deferred income taxes. The asset and liability method requires recognition
of

                   UNITED DENTAL CARE, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED
 
deferred tax assets and liabilities for the estimated future tax consequences
attributable to differences between the financial statement bases and the tax
basis of assets and liabilities. See Note 7 for additional information.
 
     NET INCOME PER COMMON SHARE: Net income per common share is computed by
dividing net income by the weighted average number of common shares and dilutive
common stock equivalents outstanding during each period. Net income per common
share has been restated to reflect a two-for-one stock dividend that was
declared on July 17, 1995. The weighted average number of common shares and
dilutive common stock equivalents used in the calculation of net earnings per
common shares was 4,662,143; 4,716,713; 5,448,892 and 7,222,149 for the years
ended December 31, 1993, 1994, 1995, and the six months ended June 30, 1996,
respectively. Pursuant to the requirements of the Securities and Exchange
Commission, common stock equivalent shares issued at prices below the original
assumed public offering price of $18.00 per share during the twelve months
immediately preceding the date of the initial filing of the Registration
Statement related to the Company's initial public offering have been included in
the calculation of common shares and common equivalent shares using the treasury
stock method, as if they were outstanding for all periods presented.
 
     USE OF ESTIMATES: The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     UNAUDITED INTERIM FINANCIAL STATEMENTS: The unaudited interim financial
statements include all adjustments, consisting only of normal recurring
accruals, which the Company considers necessary for a fair presentation of the
financial position of the Company as of June 30, 1995 and 1996 and the results
of operations for the six months ended June 30, 1995 and 1996, as presented in
the accompanying unaudited interim financial statements.
 
2. ACQUISITIONS OF INTERNATIONAL DENTAL HEALTH, INC. AND U.S. DENTAL MANAGEMENT,
INC.
 
     Effective September 1, 1994, the Company completed the acquisition of all
of the outstanding common stock of International Dental Health, Inc. ("IDH") for
$19.7 million, composed of $14.3 million in cash at the closing and additional
payments of $5.4 million over the six year period beginning September 16, 1994.
The cash portion of the purchase price was financed through bank borrowings of
$11.0 million and internal funds of $3.3 million.
 
     The acquisition has been accounted for as a purchase and the net assets and
results of operations of IDH and its subsidiaries have been included in the
Company's consolidated financial statements beginning September 1, 1994. The
purchase price has been allocated to assets and liabilities of IDH based on
their estimated respective fair values. The purchase price exceeded the fair
value of IDH's net assets by $16.1 million of which $15.7 is recorded as
goodwill at the parent company level and $0.4 is recorded as the value of
non-competition and consulting agreements. The Company has not allocated any
portion of the purchase price to any other intangible assets considered to have
nominal value such as the dentist networks and subscriber contracts. Assets
acquired and liabilities assumed totaled $13.9 million and $9.6 million,
respectively.
 
     Effective November 1, 1995, the Company completed the acquisition of all of
the outstanding common stock of U.S. Dental Management, Inc. ("US Dental") for
$12.6 million, composed of $1.3 million in cash at the closing, principal
payments totaling $1.0 million over the three year period beginning November 30,
1995 and an additional payment of $10.3 million in January 1996 from an amount
held in escrow.
 
     The acquisition has been accounted for as a purchase and the net assets and
results of operations of US Dental and its subsidiaries have been included in
the Company's consolidated financial statements beginning November 1, 1995. The
purchase price has been allocated to assets and liabilities of US Dental based

estimated respective fair values. The purchase price exceeded the fair value of
US Dental's net assets by $11.9 million of which $11.7 is recorded as goodwill
and $0.2 is recorded as the value of non-competition and consulting agreements.
The Company has not allocated any portion of the purchase price to any other
intangible assets considered to have nominal value such as the dentist networks
and subscriber contracts. Assets acquired and liabilities assumed totaled $4.3
million and $3.6 million, respectively.
 
     The following represents the unaudited pro forma results of operations as
if the IDH and US Dental acquisitions had occurred at the beginning of 1993

3. REGULATORY DEPOSITS
 
     At December 31, 1995, regulatory deposits were recorded at cost and
consisted of $1,453,000 in U.S. government obligations that renew in 1996 and
$1,702,000 in certificates of deposit insured by the Federal Deposit Insurance
Corporation. The Company has set aside certificates of deposit bearing interest
at variable rates as required by various state statutes. The fair value of all
financial instruments, determined by reference to market data, approximated
their recorded value at each of the balance sheet dates shown.
 
4. ACQUISITION-RELATED EXPENSES
 
     Certain expenditures related to the acquisitions of IDH and US Dental
discussed in Note 2 that have not been included in the costs of the acquisitions
are reported separately for comparability of expense categories to prior
reported periods. These costs are primarily related to upgrades to UDC's
facilities and computer systems necessitated by the acquisitions.
 
5. LONG-TERM DEBT
 
     On September 16, 1994, in conjunction with the acquisition of IDH (see Note
2), the Company borrowed $11.0 million from a commercial bank under a reducing
revolver arrangement. The interest rate on the unpaid principal amount was, at
the Company's option (i) 1.0% per annum over the lender's prime rate or (ii)
2.75% per annum over LIBOR. Interest payments are due at least quarterly. On
December 15, 1994, the Company repaid $275,000, on February 17, 1995, the
Company repaid $275,000, on March 15, 1995, the Company repaid $1.5 million of
such indebtedness and on September 27, 1995, the Company repaid $9.9 million,
the entire remaining balance.
 
     An additional portion of the IDH purchase price was deferred and is payable
over the period ended January 1, 2000. The payments may be prepaid without
penalty and are not contingent upon the future operations of the Company. The
present value of the future payments (assuming no voluntary prepayments,
discounted at 7.25%) is recorded as long-term debt. One of the former
shareholders of IDH was subsequently appointed a director to the Company. On
September 16, 1994, the Company made the first of the payments required under
the agreements in a total amount of $755,000. The Company entered into a letter
of credit

facility relating to the deferral agreements that requires annual fees of 1% of
the unpaid amounts under these agreements.
 
     A portion of the US Dental purchase price was financed by a Promissory Note
in the amount of $10.31 million that was subsequently paid in full on January
18, 1996. In addition, a portion of the US Dental purchase price in the amount
of $1.0 million was deferred and is payable over the period ended December 31,
1999. The payments may be prepaid without penalty and are not contingent upon
the future operations of the Company. The present value of the future payments
(assuming no voluntary prepayments, discounted at 7.50%) is recorded as
long-term debt. On November 30, 1995, the Company made the first of the payments
required under the agreements.

     In September 1995, the Company incurred an extraordinary charge due to the
early retirement of debt in the amount of $142,000, net of a tax benefit in the
amount of $73,000.
 
     The Company pays premium taxes in lieu of state income taxes in most states
where it has operations. The Company paid no state income taxes in 1993 and
immaterial amounts in 1994 and 1995.
 
     In January 1993, the Company adopted SFAS 109. The cumulative effect of
this change in accounting principle decreased net income by $44,000, which is
reflected separately in the consolidated statement of income for the year ended
December 31, 1993.
 
     During 1993, 1994 and 1995, certain employees exercised 12,500, 26,083 and
171,500 nonqualified stock options, respectively, resulting in tax savings of
approximately $31,000, $73,000 and $527,000, respectively, and a corresponding
increase to capital.

9. STOCKHOLDERS' EQUITY
 
     On September 21, 1995, the Company completed its initial public offering of
common stock, issuing 2,375,000 shares at a price of $22.00 per share before
expenses. After deduction of underwriting discounts and expenses of the
offering, the aggregate net offering proceeds were $48.0 million.
 
     On December 15, 1993, the holders of the preferred stock converted 194,871
shares of preferred stock into 463,976 shares of the common stock. At December
31, 1993 and December 31, 1994, there was one share of preferred stock
outstanding. In April 1995, the one share of preferred stock was converted into
2 shares of common stock. Certain of the Company's subsidiaries are subject to
various state insurance regulations, some of which restrict the payment of
dividends within the consolidated group. See Note 10.
 
     The Company had an Incentive Stock Option Plan pursuant to which 200,000
shares of common stock were reserved. During 1994 and 1995, 60,000 and 80,000
stock options were exercised, respectively, at an exercise price of $1.25 per
share. These options are considered noncompensatory. The board of directors has
terminated the Incentive Stock Option Plan for the purposes of any additional
grants thereunder.
 
     The Company also has a Key Employee Stock Option Plan pursuant to which
332,000 shares were reserved as of December 31, 1995. During 1995, 263,500 stock
options were exercised at an average exercise price of $1.39. At December 31,
1995, none of the 332,000 outstanding Key Employee Stock Option Plan options
were exercisable. These options are considered compensatory and have terms of
five to ten years; the options are exercisable at various times during the terms
of the options at exercise prices ranging from $1.25 to $6.25, which amounts, in
management's estimation, were equal to or exceeded market value at the date of
grant. The board of directors has terminated the Key Employee Stock Option Plan
for the purposes of any additional grants thereunder.
 
     In 1995, the Company's board of directors adopted a new employee stock
option plan (the "1995 Plan") that provides only for the grant of nonqualified
stock options. The 1995 Plan provides that a total of 300,000 shares of common
stock may be issued pursuant to the options granted under the 1995 Plan. At
December 31, 1995, options for 42,000 shares had been granted under the 1995
Plan.

     In October 1995, the FASB issued Statement of Financial Accounting
Standards No. 123 ("FAS-123") "Accounting for Stock-Based Compensation," which
becomes effective for fiscal years beginning after December 15, 1995. FAS-123
establishes new financial accounting and reporting standards for stock-based
compensation plans. Entities will be allowed to measure compensation under
FAS-123 or APB Opinion No. 25, "Accounting for Stock Issued to Employees."
Entities electing to remain with the accounting in APB Opinion No. 25 will be
required to make pro forma disclosures of net income and earnings per share as
if the provisions of FAS-123 had been applied. The Company will continue to
measure compensation cost for stock-based compensation under APB Opinion No. 25
and will make the required disclosures for the year ending 1996.
 
10. STATUTORY NET WORTH COMPARED TO STOCKHOLDERS' EQUITY PER GENERALLY ACCEPTED
    ACCOUNTING PRINCIPLES
 
     Certain assets recognized under generally accepted accounting principles
are considered nonadmissible under statutory accounting practices as filed and
submitted in the annual reports to the states of domicile of the various
subsidiaries required to submit such reports. These nonadmitted assets create
differences between statutory net worth as reported on the annual filing and
total stockholders' equity as recorded under generally accepted accounting
principles.
 
     Statutory net worth of the Company's subsidiaries that are subject to state
insurance regulations totaled approximately $7 million and $18 million at
December 31, 1994 and 1995, respectively. Of these amounts, National Dental
Health Insurance Company (NDHIC) represents $4.3 million and $6.3 million at
December 31, 1994 and 1995, respectively. NDHIC is subject to the Arizona
insurance statutes and regulations and is required to maintain minimum capital
and surplus of $500,000 and without the prior

approval of the Arizona Department of Insurance may not pay a dividend greater
than the lesser of 10% of capital and surplus as of the end of the prior year or
net investment income for the prior year. NDHIC received approval from the
Arizona Department of Insurance to pay a dividend of $315,000 in 1994.
 
     At December 31, 1993 and for the year then ended, the difference between
statutory net worth and net income under the statutory accounting practices and
total stockholders' equity and net income as recorded under generally accepted
accounting principles was not material. Statutory net income of the Company's
subsidiaries for 1994 and 1995 was $4.6 million and $6.3 million, respectively,
and excludes a $3.9 million intercompany realized gain on the transfer of
subsidiaries among affiliates.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Stockholders and Board of Directors of
  OraCare Dental Health Plans, Inc.
 
     We have audited the accompanying combined balance sheets as of December 31,
1994 and 1995, of the entities listed in Note 1, and the related combined
statements of income, changes in stockholders' deficiency and cash flows for the
years then ended. 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 combined financial position at December 31, 1994
and 1995, of the entities listed in Note 1, and the combined results of their
operations and their cash flows for the years then ended, in conformity with
generally accepted accounting principles.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     ORGANIZATION: The accompanying combined financial statements include the
accounts of the following entities collectively doing business as OraCare Dental
Health Plans, Inc.: OraCare Investors (a Partnership), OraCare Consultants, Inc.
("OC"), OraCare D.P.O., Inc. ("DPO"), OraCare Dental Labs, Inc. ("ODL"), and
prior to February 1, 1995, OraCare Dental Health Center -- Vineland, OraCare
Dental Health Center -- Blackwood, OraCare Dental Health Center -- Greentree,
OraCare Dental Health Center -- Atlantic City (the "Health Centers"). On
February 1, 1995, the Health Centers were combined into a single corporation
known as OraCare Dental Associates, P.A. ("ODA"). All of the outstanding stock
of these corporations are owned by members of a single family. The Board of
Directors of the corporations consists of the same individuals. OraCare
Investors, OC, DPO, ODL and ODA are collectively referred to hereinafter as the
"Company". The Company operates and markets managed dental care plans in New
Jersey and Pennsylvania. The Company also operates multi-specialty group dental
practices which provide services to plan members as well as out-of-plan
patients. The Company markets managed dental care plans to health maintenance
organizations (HMO's) and other groups as an alternative to traditional dental
indemnity insurance. With the exception of OraCare Investors, all organizations
within the Company operate as New Jersey corporations and are established as
S-Corporations for Federal income tax purposes.
 
     OC provides administrative and marketing services to DPO, ODL and ODA. OC
is wholly-owned by five members of the Board of Directors.
 
     DPO provides dental services to managed care corporations and other
employers in need of managed dental services. DPO is licensed under the New
Jersey Department of Insurance to operate as a prepaid dental plan organization
under the "Dental Plan Organization Act" ("DPO Act"). DPO enters into dental
agreements with each dentist who provides dental services for DPO enrollees.
Consistent with the DPO Act, DPO is limited to the amount of underwriting risk
it can assume. The Department of Insurance must approve all new or revised
schedule of charges prior to its effective date. In accordance with the DPO Act,
the charges must not be excessive, inadequate or unfairly discriminatory. Among
other provisions, the DPO Act requires DPO to meet certain net worth and deposit
requirements discussed more fully in Note 3. It is management's opinion that DPO
was in compliance with these provisions as of December 31, 1994 and 1995. DPO is
wholly-owned by the Chairman of the Board of Directors.
 
     ODL provides laboratory work for the Company and outside dentists. ODL is
wholly-owned by the Chairman of the Board of Directors.
 
     ODA consists of dental health centers located throughout New Jersey. The
Health Centers provide multi-specialty dental services including pediatric
dentistry, oral surgery, endodontics, orthodontics and periodontics. Dentists
within the Health Centers are compensated a fixed salary plus bonus incentives.
The bonus incentives are contingent upon meeting certain productivity targets.
Under some plans, the dentist is also paid a separate fee, or co-payment, by the
member at the time of the dental service. Dental service costs of dentists
within the Health Centers consisted of approximately 36% and 32% of total dental
service costs at December 31, 1994 and 1995, respectively. All Health Centers
are wholly-owned by the Chairman of the Board of Directors.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     PRINCIPLES OF COMBINATION: The accompanying combined financial statements
include the financial statements of each organization within the Company. All
intercompany transactions and balances have been eliminated in combination.
 
     REVENUE: Amounts billed to out-of-plan patients are recognized as revenue
in the month in which services are rendered. Revenue is recognized on group
policy holders and prepaid arrangements in the month
 
                                      F-21

              NOTES TO COMBINED FINANCIAL STATEMENTS -- CONTINUED
 
in which the subscribers are entitled to receive services. Unearned fees are
reflected as current liabilities and consist of amounts billed in the current
period for services to be rendered in a subsequent period.
 
     Under prepaid arrangements, the DPO contracts with dentists for dental
services to be provided to its subscribers. Provider capitation consists of
monthly fees paid to dentists and is expensed in the month in which the dentist
is obligated to render dental services. DPO is not obligated to dentists for
services exceeding the capitated payment.
 
     DENTAL SERVICE COSTS: Indemnity and managed care dental expenses are
charged to expense in the period that the services are incurred. The Company
contracts with dentists not compensated by the Health Centers to provide
services to covered enrollees. These costs consist of compensation to dentists
participating in the managed dental care plan and are paid by the Company on a
per member, per month capitation basis. Dental provider contracts are on a
yearly basis subject to cancellation by either party upon 90 days written
notice. Dental provider contracts consisted of approximately 5% and 12% of
dental service costs for the years ended December 31, 1994 and 1995,
respectively.
 
     PROPERTY AND EQUIPMENT: Property and equipment is recorded at cost.
Depreciation is provided on a straight-line basis over the estimated useful life
of the asset. Capitalized leases are recorded at their present value at the
inception of the lease. Equipment under capital leases is amortized on the
straight-line method over the shorter period of the lease term or the estimated
useful life of the equipment.
 
     STATE INCOME TAXES: For federal income tax purposes, the corporations
within the Company have elected to be treated as S corporations and,
accordingly, federal income taxes are not provided for by the Company. The
corporations within the Company are subject to New Jersey state income taxes.
During 1994, the Company had sufficient state net operating loss carryforwards
to offset taxable income. State income taxes are based on income reported for
financial statement purposes, adjusted for permanent differences. Permanent
differences principally relate to the non-deductible portion of travel and
entertainment expenses and premiums paid for officers' life insurance. The
Company utilized operating loss carryforwards for state tax purposes of
approximately $667,000 and $140,000 for the years ended December 31, 1994 and
1995, respectively. At December 31, 1995, there are no remaining net operating
loss carryforwards available.
 
     MALPRACTICE INSURANCE: In addition to individual dentist coverage, the
Company maintains claims made umbrella policies covering employed dentists and
other dental professionals. The policies have a $1,000,000 occurrence and

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND DESCRIPTION OF BUSINESS
 
     The accompanying combined financial statements include the accounts of the
following entities collectively doing business as UICI Dental Companies ("the
Companies"): United Dental Care of Oklahoma ("UDC-Oklahoma") and its wholly
owned subsidiary, UDC Life and Health Insurance Company, International Dental
Plan, Inc. ("IDP") and Association Dental Plans, Inc. ("ADP"). Any intercompany
transactions and balances have been eliminated in combination.
 
     Each of these companies was acquired by UICI (formerly known as United
Insurance Companies, Inc.) ("UICI") during 1995. UICI is a publicly-traded
financial services company with interests in life and health insurance and
related services, including the administration and delivery of managed health
care program to select niche markets. In early 1995, UICI purchased a majority
interest in UDC-Oklahoma from its controlling stockholder. In November 1995,
UICI acquired 100% of the stock of ADP and, in December 1995, acquired 100% of
the stock of IDP. The accompanying combined financial statements present 100% of
the financial position and results of operations of UDC-Oklahoma
 
     On September 10, 1996, UICI entered into a definitive agreement with United
Dental Care, Inc. ("UDC"), a publicly-traded prepaid dental plan unrelated to
UDC-Oklahoma, to sell 100% of the stock of IDP and ADP and their majority
interest in UDC-Oklahoma to UDC including a tender offer of the minority
interest in UDC-Oklahoma, for $12,500,000.
 
     Both UDC-Oklahoma and IDP are licensed to operate and market managed dental
care plans in the states of Oklahoma and Florida, respectively. ADP is a
"referral-type" plan which operates a nationwide fee-for-service membership
plan. A "referral plan" generally is not considered an insurance product in most
states.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  REVENUE RECOGNITION
 
     Premium revenue related to managed benefits is recorded in the month for
which the member is entitled to service. Premium revenue for indemnity benefits
is recognized over the coverage period to which the premiums relate. Member fees
related to ADP's fee-for-service membership plan are reported as revenue in the
period in which the member is entitled to plan benefits. Unearned premiums and
member fees are reflected as deferred revenue and consist of amounts billed or
collected in the current period which pertain to services (or entitlement to
services) in subsequent periods.
 
  REGULATORY DEPOSITS
 
     Under Florida law, IDP is required to maintain a minimum surplus of
$100,000 or 6% of total liabilities, whichever is greater. As of January 1,
1996, this increased to the greater of $150,000 or 10% of total liabilities. In
addition, an interest bearing deposit of $50,000 with the Florida Department of
Insurance and a fidelity bond on its officers and employees in an amount at
least equal to $50,000, is also required. As of December 31, 1995, IDP had
statutory surplus of approximately $496,000.
 
     Under Oklahoma law, UDC-Oklahoma is required to keep interest-bearing
certificates of deposit issued by solvent insured banks and trust companies in
Oklahoma on deposit with the State Treasurer. The required deposit is held by
the State Treasurer in trust for the benefit and protection of persons covered
by the Plan and is not subject to attachment by any creditors.
 
  CASH AND CASH EQUIVALENTS
 
     The companies consider all highly liquid investments with an original
maturity of three months or less to be cash equivalents.

  TEMPORARY INVESTMENTS
 
     Temporary investments include assets which are fully bonded or guaranteed
by the United States Government, such as bank Certificates of Deposit covered by
FDIC insurance, mutual funds invested exclusively in US Government debt
instruments and Repurchase Agreements backed by US Government securities. Time
deposits have an original maturity of greater than three months. Temporary
investments are recorded at cost which approximates market.
 
  MARKETABLE SECURITIES
 
     In accordance with FAS 115, the Companies have treated their marketable
securities as held to maturity type investments and have recorded them at cost.
Marketable securities consist of a US Treasury Note with a cost of $700,000 as
of December 31, 1995. The market value of the US Treasury Note was $700,000 as
of December 31, 1995. The note accrues interest at 4.25%.
 
  MORTGAGE LOANS
 
     Mortgage loans are stated at the aggregate unpaid balance.
 
  FUTURE POLICY BENEFITS
 
     The reserves for future policy benefits are computed in accordance with
state statutes and administrative regulations. The aggregate reserve for
accident and health policies consists of reserves for unearned premiums and
reported and incurred but not reported on life and annuity claims. The unearned
premiums reserve represents the portion of premiums paid in advance which have
not yet been earned.
 
     The aggregate reserve for life and annuity policies represents the
actuarially determined present value of amounts not yet due on claims.
 
  PROPERTY AND EQUIPMENT
 
     Furniture and equipment are carried at cost, and are depreciated using the
straight line and double declining balance methods over estimated useful lives
of three to seven years. Leasehold improvements are carried at cost and
depreciated over fifteen years. Upon disposition, the cost and related
accumulated depreciation are removed from the accounts and the resulting gain or
loss is reflected in operations of the period.
 
  ACQUISITION COSTS
 
     Acquisition costs, such as commissions and other costs of obtaining new
members, are expensed as incurred.
 
  INCOME TAXES
 
     The Companies use SFAS No. 109, "Accounting for Income Taxes", which
requires an asset and liability approach to financial accounting and reporting
for income taxes. The difference between the financial statement and tax basis
of assets and liabilities is determined annually. Deferred income tax assets and
liabilities are computed for those differences that have future tax consequences
using the currently enacted tax laws and rates that apply to the periods in
which they are expected to affect taxable income. Valuation allowances are
established, if necessary, to reduce the deferred tax asset to the amount that
will, more likely than not, be realized.

              NOTES TO COMBINED FINANCIAL STATEMENTS -- CONTINUED
 
     The principal source of temporary differences giving rise to the deferred
tax liability relate to differences in tax basis and financial reporting amounts
of property and equipment, net of accumulated depreciation which result from the
use of accelerated depreciation for income tax purposes.
 
  USE OF ESTIMATES
 
     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 December 31, 1995 and June
30, 1996, and revenues and expenses during the periods then ended. The actual
outcome of the estimates could differ from the estimates made in the preparation
of the financial statements.

     Property and equipment at December 31, 1995 consist of the following:

</TABLE>
 
     The UDC-Oklahoma notes payable consist of two promissory notes in the
amount of $100,000 and $450,000 payable on demand, but no later than December
31, 1997, and August 26, 1997, respectively. Interest is due monthly at an
annual rate equal to the net investment yield earned on the principal as
invested by UDC-Oklahoma's wholly-owned subsidiary, UDC Life and Health
Insurance Company. These notes are collateralized by 500,000 shares of the
capital stock of UDC Life and Health Insurance Company, and provide for certain
restrictions on UDC-Oklahoma to incur borrowings, sell assets, enter into
reinsurance agreements and invest assets. The notes are payable to The Mega Life
and Health Insurance Company ("MEGA"), formerly United Group Insurance Company.
One of MEGA's officers is a board member of UDC-Oklahoma.
 
     In addition, UDC-Oklahoma has a revolving line of credit available from
MEGA. The amount of borrowings that can be made under this revolving line of
credit is restricted by certain financial requirements of MEGA. The maximum
amount that could be borrowed under the revolving line of credit is $850,000.
Borrowings under the line of credit shall bear interest at the rate of 1% per
month. As of December 31, 1995, no borrowings have been made against the line.
 
     The ADP debt consists of a promissory note in the amount of $502,475 and a
line of credit of $153,000, both payable to UICI. Interest is paid monthly, and

     UDC-Oklahoma has authority to issue two classes of preferred stock, Class
A, and Class B. Holders of the Class B preferred stock are entitled to receive a
fixed yearly dividend of 14% payable as authorized by the directors. This
dividend, which is cumulative, is to be set aside or paid before any dividends
are paid on the Class A preferred stock or common stock. The Class A preferred
stockholders are entitled to a 12% annual cumulative dividend which is to be set
aside or paid before the common stock dividends. The holders of common stock are
entitled to receive all moneys appropriated to dividends, after the cumulative
dividends on Class A and B preferred stocks have been fully paid. In 1995, only
common stock shares were outstanding.
 
     In connection with the revolving line of credit discussed in Note 4,
UDC-Oklahoma issued a warrant which was exercisable up to an aggregate of 3,125
shares of its common stock at a price of $100 per share through April 1996.
Subsequent to December 31, 1995 this warrant was exercised and 3,125 shares of
common stock were issued.
 
     In June 1993, the sole stockholder of UDC-Oklahoma approved a 1 for 200
reverse stock split. As of December 31, 1995, UDC-Oklahoma had repurchased
24,883 fractional shares (124 shares after the effect of the reverse stock
split) for $1.12 per share. These shares have been recorded in the financial
statements as treasury stock. Management estimates that approximately 15,760
fractional shares (79 shares after the effect of the reverse stock split) have
not yet been redeemed. Management expects these shares will be redeemed in the
future.

     UDC-Oklahoma leases office equipment from United Management and Consulting,
Inc. ("UMCI"), a company owned by a stockholder and officer of UDC-Oklahoma.
Lease payments made under the cancelable lease agreement amounted to $25,200 in
1995.
 
     Included in selling, general and administrative expenses are management and
consulting fees charged by a professional association owned by certain former
shareholders of IDP totaling approximately $71,000 in 1995. Additionally, during
1995 consulting fees of $23,000 were charged by a former shareholder of IDP.
During 1995, management fees of $90,698 were paid to an officer of UDC-Oklahoma
for management and consulting services in lieu of salary.
 
     Included in interest and other revenues in the accompanying statement of
operations is approximately $2,500 in net settlement income resulting from the
collection of approximately $601,000 in damages relating to a claim filed by IDP
in 1988, settled in 1991 and collected in 1995. IDP then paid bonuses to certain
employees in recognition of their contributions to the recovery related to this
claim and paid approximately $347,500 to a professional partnership owned by
certain former shareholders for professional services principally rendered in
prior years in connection with the claim. In connection with this claim, IDP
entered into an agreement with the professional partnership owned by certain
former shareholders whereby the professional partnership would be entitled to
additional amounts, up to $150,000, that may be received in the future. In July
1996, IDP received an additional $346,000 in damages as final settlement of this
claim, $150,000 of which was disbursed to the professional partnership in
accordance with the agreement noted above.

provision for income tax differs from the amount computed by applying the
Federal statutory rate primarily due to the effect of a small life insurance
company deduction of 60% of life insurance company taxable income.
 
     UDC-Oklahoma generally pays premium taxes in lieu of state income taxes.
 
8. PROFIT SHARING PLAN
 
     During 1995, the Companies maintained qualified 401(k) profit-sharing plans
covering substantially all of their employees. The plans allow for employees to
contribute a percentage of their compensation up to the maximum limit allowable
by law. The plans also provide for a discretionary matching contribution by the
companies which totaled approximately $52,951 in 1995. The IDP plan was
terminated effective December 31, 1995, in connection with the Agreement and
plan of Exchange with UICI. The ADP plan was terminated effective December 31,
1995, at which time ADP adopted the UICI 401(k) plan.
 
9. OPERATING LEASE
 
     The Companies lease office space and office equipment under various
noncancelable lease agreements. Rental expense for the year ended December 31,
1995 was $161,973. Future minimum lease payments required under the operating
leases as of December 31, 1995, are as follows:

10. RISKS AND UNCERTAINTIES
 
     The Companies contract with certain medical HMOs to provide dental benefits
to the HMO's members. In the event that the contracts between such HMOs and
significant customers (e.g., government programs such as Medicare or Medicaid,
major employer groups) are terminated or not renewed, such termination or
nonrenewal would also terminate the companies' contracts to provide dental
benefits to those HMOs. Furthermore, the contracts with the medical HMOs
generally are on a year-to-year basis. Decisions by any of the medical HMOs to
not renew the contracts (i.e., to change to a different dental care provider
organization, or to drop dental coverage as a plan benefit) could result in
significant membership loss.
 
     The companies contract to provide services to government programs such as
Medicare and Medicaid, either though contractual relationships with medical HMOs
(as discussed above) or by contracting directly with the government program.
Changes in reimbursement regulations could have an impact on the amounts of
payments received under such contracts or on the timing of the payments received
under those contracts.
 
     In 1996 IDP lost a major customer, PCA, through which it provided dental
benefits to approximately 62,000 Florida Medicaid beneficiaries.

                        REPORT OF INDEPENDENT ACCOUNTANT
 
To the Board of Directors of
  Kansas City Dental Care, Inc.
 
     I have audited the accompanying balance sheet of Kansas City Dental Care,
Inc. as of December 31, 1995, and the related statements of income, retained
earnings and cash flows for the year then ended. These financial statements are
the responsibility of the Company's management. My responsibility is to express
an opinion on these financial statements based on my audit.
 
     I conducted my audit in accordance with generally accepted auditing
standards. Those standards require that I 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.
I believe that my audit provides a reasonable basis for my opinion.
 
     In my opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Kansas City Dental Care,
Inc. as of December 31, 1995 and the results of its operation and its cash flow
for the year then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
1. NATURE OF OPERATIONS
 
     Kansas City Dental Care, Inc., a Missouri corporation, is a prepaid dental
care insurance company. The plan provides members with affordable, quality
dental care in an era of spiraling health care costs. Members of Kansas City
Dental Care, Inc. subscribe to coverage through a payroll deduction by their
employer, and may continue coverage upon separation from their employer by
renewing their subscription on an individual basis. Services are provided to
members by contracting dentists throughout the area.
 
2. BASIS OF ACCOUNTING
 
     Financial statements are prepared on the accrual basis of accounting.
Revenues are recorded at the time of the sale or transaction. Expenditures are
recorded at the time the merchandise or service is received.
 
3. INVESTMENTS
 
     Bonds and short-term investments are reported at amortized cost. Discounts
or premiums on bonds are amortized using the straight-line method. Interest
earned on investments is being accrued.
 
4. ACCOUNTS RECEIVABLE
 
     Accounts receivable are stated at net realizable value. Doubtful accounts
are written directly to expense when in the opinion of management, amounts
involved are considered uncollectible, which approximates the allowance method
of bad debt write-off.
 
5. FIXED ASSETS
 
     Fixed assets are stated at cost. Major improvements and betterments to
existing fixed assets have been capitalized. Expenditures for maintenance and
repairs which do not extend the life of the applicable fixed assets have been
charged to expense as incurred.
 
     Depreciation is provided principally by the straight-line method over the
estimated useful lives of the assets.
 
6. ACCRUED LIABILITIES
 
     Accrued liabilities are based on the accrual method of accounting and are
computed through December 31, 1995.
 
     Unearned premiums are determined by prorating policy premiums over the
terms of the policies.
 
7. INCOME TAXES
 
     Income taxes are provided for the tax effects of transactions reported in
the financial statements and consist of taxes currently due plus deferred taxes
related to temporary differences in reporting results of operations for income
tax and financial accounting purposes.
 
8. USE OF ESTIMATES
 
     The preparation of financial statements on the accrual basis of accounting
requires management to make estimates and assumptions that affect certain
reported amounts and disclosures. Accordingly, actual results could differ from
those estimates.

purchased during the year ended November 30, 1991 for $49,437.50. The amortized
cost of the bond at December 31, 1995 and June 30, 1996 is $49,702 and $49,731,
respectively, which approximates market value. The bond matures February 15,
2001. The fair market value as of December 31, 1995 and June 30, 1996 is $55,094

office space until July 31, 2000. Monthly rent in the amount of $4,956.75 is
payable until July 31, 1998. Monthly rent will be $5,140.33 from August 1, 1998
through the end of the lease.
 
NOTE E -- 401(K) PLAN
 
     Kansas City Dental Care, Inc. has in place a 401(k) plan which provides for
elective deferral of salaries for employees. The Company also invests a base
amount of 3% to all employees vested and will match employee contributions up to
an additional 4%. Contributions for the year ended December 31, 1995 and for the
six months ended June 30, 1996 of $52,145 and $33,309, respectively, reflect

                        REPORT OF INDEPENDENT ACCOUNTANT
 
To the Board of Directors and Stockholders of
  U.S. Dental Management, Inc.
 
     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of changes in stockholders'
equity and of cash flows present fairly, in all material respects, the financial
position of U.S. Dental Management, Inc. and its subsidiaries at December 31,
1994 and 1993, and the results of their operations and their cash flows for each
of the three years ended December 31, 1994, 1993 and 1992, in conformity with
generally accepted accounting principles. 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 of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                 U.S. DENTAL MANAGEMENT, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Basis of Presentation: The consolidated financial statements include the
accounts of U.S. Dental Management, Inc. and its subsidiaries ("US Dental"). All
significant intercompany accounts and transactions have been eliminated in
consolidation. The company, through its subsidiaries, contracts with independent
practitioners to provide dental services to members in the form of pre-paid
dental health contracts.
 
     Cash and Cash Equivalents: US Dental considers debt instruments purchased
with a maturity of three months or less to be cash equivalents.
 
     Property and Equipment: Property and equipment are recorded at cost.
Depreciation is determined using the declining balance method over useful lives
of five to seven years.
 
     Income taxes: US Dental and its subsidiaries file a consolidated income tax
return for federal income tax purposes. The subsidiaries of US Dental are
required to pay the State Treasurer a tax (premium tax) for transacting business
as a prepaid dental plan. The subsidiaries are exempt from state corporate
income tax due to the payment of the premium tax.
 
     Significant Customer: During 1994 one customer accounted for approximately
16% of the aggregate revenue of US Dental.
 
     Prior period adjustment: The prior period adjustment for the year ended
December 31, 1993, resulted from the payment of additional taxes not previously
accrued. The adjustment for the year ended December 31, 1994, resulted from the
write off of certain expenses that were incorrectly capitalized.
 
2. UNEARNED REVENUE
 
     Unearned revenue consists of subscriber fees received or billed in the
current year for services to be rendered in a subsequent year.
 
3. STATUTORY RESERVE
 
     Prepaid dental plan organizations are required to maintain a reserve in an
amount equal to two percent of subscription fees received, up to a maximum
reserve of $500,000 per state. These reserves are included in retained earnings.
 
4. DENTAL CARE SERVICE
 
     Under prepaid dental health contracts, US Dental contracts with dentists
for a set per member per month capitation fee to provide for its members.
Specialty services not covered by capitation fees are recorded as incurred. In
addition, US Dental is liable for out of area emergency care for subscribers
under certain benefit packages. Subscriber reimbursements amounted to $20,000,
$16,000, and $7,000 in 1992, 1993 and 1994, respectively, and were recorded as
incurred.
 
5. REGULATORY DEPOSIT AND FINANCIAL INSTRUMENTS
 
     State codes provide that prepaid dental plans shall maintain trust funds,
varying according to membership, with the Department of Insurance. The
regulatory deposits consist of certificates of deposit. The fair value of all
financial instruments, determined by reference to market data, approximated
their recorded value at each of the balance sheet dates shown.
 
6. LONG-TERM OBLIGATIONS
 
     At December 31, 1994, there were 3 notes payable totaling $27,000 with
monthly payments ranging from $550 to $2,500, at interest rates ranging from 5%
to 11% maturing through March 1996.

8. PROFIT SHARING AND RETIREMENT PLAN
 
     Pursuant to section 10-044 of the Arizona Revised Statutes, US Dental

expensed in 1992, 1993 and 1994, respectively.
 
     US Dental adopted a Defined Contribution plan (Profit Sharing). The basis
for determining contribution amounts are under the discretionary contribution
plan of the IRS 401L disparity rules. The groups covered under the plan are the
shareholders and employees of U.S. Dental Plan of New Mexico, Inc. and U.S.
Dental Management, Inc. hired prior to July 1, 1989. There were no contributions
expenses for the year ended December 31, 1994.
 
9. BANK LINE-OF-CREDIT
 
     US Dental has a bank line-of-credit for $300,000 which renewed April 15,
1995. There was an outstanding balance as of December 31, 1994 of $275,000.
Borrowings thereunder bear interest of 1.25% above the bank's prime rate. The
line is collateralized by US Dental's accounts receivable and is personally
guaranteed by US Dental's shareholders.
 
10. NOTES PAYABLE OFFICERS
 
     Notes payable to officers consist of amounts due to shareholders, bearing
interest ranging from 7% to 9.5% and due upon demand.
 
11. INCOME TAXES

rate is as follows:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
  Associated Health Plans, Inc. and
  Associated Companies, Inc.
 
     In our opinion, the accompanying combined balance sheet and the related
statement of operations and retained earnings and of cash flows present fairly,
in all material respects, the combined financial position of Associated Health
Plans, Inc. and Associated Companies, Inc., as described in the basis of
financial statement presentation in Note 1 to the financial statements, at
December 31, 1995 and the results of its operations and its cash flows for the
year then ended, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Associated Health
Plans, Inc. and Associated Companies, Inc. management; our responsibility is to
express an opinion on these statements based on our audit. We conducted our
audit of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
1. AHP AND ITS OPERATIONS
 
     At December 31, 1995, four individuals owned 100% of the common stock of
both Associated Health Plans, Inc. (Associated) and Associated Companies, Inc.
(ACI). Associated and ACI are referred to collectively as "AHP."
 
     Associated operates as a prepaid dental plan in the state of Arizona.
Associated is licensed by the state of Arizona to operate as a prepaid dental
plan organization as defined under Article Seven of the Arizona Revised
Insurance Statutes.
 
     Associated sells group prepaid dental coverage on a monthly term basis to
contract holders consisting of business, governmental and nonprofit groups. AHP
has joint venture marketing agreements with a medical health maintenance
organization and dental indemnity insurance company. Under these agreements, the
joint venture partners sell group prepaid dental coverage for AHP. They collect
the premiums directly and remit to AHP. They also sell prepaid dental coverage
to individual contract holders on an annual basis.
 
     ACI is organized to provide management services for Associated. Under the
terms of a management agreement, ACI provides equipment and operating facilities
as well as administrative and marketing services. ACI also provides management
services for an affiliate, Associated Dental Care Providers, P.C. (ADCP) which
employs dentists and support staff who provide services primarily to individuals
under Associated's dental coverage. (See Note 5). At the date of the sale of the
common stock of Associated and ACI, all management services agreements between
ACI and ADCP were terminated.
 
     Two stockholders, who are also licensed dentists, own 100% of the common
stock in ADCP. ADCP is a major provider of dental services to members enrolled
with AHP's contract holders. During 1995, payments to ADCP amounted to
$2,789,931.
 
BASIS OF FINANCIAL STATEMENT PRESENTATION
 
     The accompanying combined financial statements include the financial
statements of ACI and Associated for the year ended December 31, 1995. Based
upon the subsequent stock sale of ACI and Associated in January 1996 (Note 5),
the accompanying combined financial statements exclude the assets and
liabilities related to servicing ADCP as well as the operational results of
servicing ADCP for the year ended December 31, 1995. All significant
intercompany transactions have been eliminated in combination.
 
     As noted above, ACI's revenues and expenses related to the management of
ADCP were excluded. The allocation of revenues and expenses can be separately
identified in the companies' general ledgers. Only those revenues and expenses
identified as relating to the management of Associated or ACI were included in
the combination.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PREMIUM EARNED AND PROVIDER CAPITATION
 
     Premiums billed to individual and group subscribers are recognized as
revenue in the month in which subscribers are entitled to receive dental care.
Unearned premiums consist of amounts collected during the current period for
services to be rendered in a subsequent period. Allowance for doubtful accounts
for uncollectible premiums under 90 days past due are recorded as an expense
when established.
 
     AHP contracts with dentists (providers) for dental services to be provided
to its subscribers. Provider capitation consists of monthly fees paid to
providers and is expensed in the month in which the provider is

                           ASSOCIATED COMPANIES, INC.
 
              NOTES TO COMBINED FINANCIAL STATEMENTS -- CONTINUED
 
obligated to render dental services. AHP is not obligated to providers for
services exceeding the basic benefit coverage. Emergency services to members
while temporarily out of their provider's area, as well as specialty services
not covered by capitation fees, are recorded as incurred.
 
CASH AND CASH EQUIVALENTS
 
     For purpose of reporting cash flows, cash and cash equivalents include cash
on hand, amounts due from banks, money market investment accounts held by
brokers which are readily convertible to cash, and certificates of deposit with
maturities at the date of purchase of less than 90 days.
 
FURNITURE AND EQUIPMENT
 
     Furniture and equipment are recorded at cost. Depreciation is calculated
using the straight-line method over a period of three to five years based on the
estimated useful life of the related asset. Depreciation expense was $43,278 in
1995.
 
INCOME TAXES
 
     Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS 109), which
requires the asset and liability method of accounting for deferred income taxes.
The asset and liability method requires recognition of deferred tax assets and
liabilities for the estimated future tax consequences attributable to
differences between the financial statement bases and the tax bases of assets
and liabilities. (Note 6)
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. INTANGIBLE ASSETS
 
     Intangible assets consist of the net present value of certain noncompete
agreements entered into in connection with the purchase of AHP from its former
stockholders in January 1992. The noncompete agreements were originally recorded
at their net present value with imputed interest rates of 11.2% and 8.5% for the
two former stockholders, respectively, and are being amortized over the ten year
term of the agreement. Under these agreements, accumulated amortization at
December 31, 1995 was $524,928.
 
4. STATE DEPOSITS
 
     AHP is required by statute to post a surety bond in the amount of $200,000
with the Arizona state treasurer. In lieu of purchasing a surety bond to
guarantee services under this plan, AHP has elected to deposit $200,000 of bank
certificates of deposit with the treasurer's office. AHP continues to receive
all interest income from the certificate of deposit held by these certificates.
 
5. SUBSEQUENT STOCK SALE OF AHP
 
     On January 22, 1996, the common stock of ACI and Associated was purchased
by United Dental Care, Inc. for $14.4 million. In connection with the purchase,
$3,548,867 of the proceeds to the sellers were used to

noncompete agreement entered into with them in connection with the stock sale of
ACI to its current stockholders in 1992. Interest expense in 1995 was $285,017.
At December 31, 1995, notes payable consisted of the following:

     In January 1996, the common stock of AHP was purchased by United Dental
Care, Inc. (UDC) and these obligations were repaid by UDC as part of the
purchase price. (Note 5)
 
8. COMMON STOCK
 
     At December 31, 1995, Associated had 900,000 of $.10 par value shares
authorized and 22,500 shares outstanding. At December 31, 1995, ACI had 20,000
shares of $.10 par value stock authorized, issued and outstanding. During 1995,
there were no changes in the numbers of shares of common stock and the amount of
common stock or in additional paid-in capital.
 
9. COMMITMENTS AND CONTINGENCIES
 
     AHP leases its facilities under noncancelable operating lease agreements
expiring at various dates through 1999. Rental expense under these agreements,
which is included in general and administrative expenses, was $117,088 in 1995.
Future minimum lease payments under these agreements are as follows:

            1998....................................................    $118,531
            1999....................................................    $ 57,300
</TABLE>
 
     As a result of the purchase by United Dental Care (Note 5), management
believes that the determination of the ultimate liability of these obligations,
after considering subleasing alternatives and a negotiated termination price,
cannot be determined at this time. Accordingly, no adjustments has been made to
the recorded lease liability.
 
     AHP is involved in certain claims. In the opinion of management, the
disposition of these matters will not have a material adverse effect on AHP's
financial condition.

                 INTRODUCTION TO UNAUDITED PRO FORMA CONDENSED
                       CONSOLIDATED FINANCIAL STATEMENTS
 
     The accompanying unaudited pro forma condensed consolidated statement of
operations for the year ended December 31, 1995 has been prepared as if both the
US Dental and AHP acquisitions and the Company's initial public offering that
occurred in September 1995 had occurred on January 1, 1995. The accompanying
unaudited pro forma condensed consolidated statement of operations for the six
months ended June 30, 1996 has been prepared as if the AHP acquisition and the
offering of the Common Stock pursuant to this Prospectus had occurred on January
1, 1995. See "Pending and Recent Acquisitions." The unaudited pro forma
condensed consolidated statement of operations for the year ended December 31,
1995 includes: (i) the historical results of operations of the Company for the
year ended December 31, 1995; (ii) the historical results of operations of AHP
for the year ended December 31, 1995; (iii) the historical results of US Dental
for the ten months ended October 31, 1995, and gives effect to the US Dental and
AHP acquisitions under the purchase method of accounting; and (iv) the Company's
initial public offering. The unaudited pro forma condensed consolidated
statement of operations for the six months ended June 30, 1996 includes: (i) the
historical results of operations of the Company for the six months ended June
30, 1996; and (ii) the historical results of operations of AHP for the month
ended January 31, 1996, and gives effect to the AHP acquisition under the
purchase method of accounting; and (iii) the offering of the Common Stock
pursuant to this Prospectus. Such unaudited pro forma condensed consolidated
statements of operations incorporate the pro forma and offering adjustments
described in the accompanying Notes to Unaudited Pro Forma Condensed
Consolidated Financial Statements.
 
     The unaudited pro forma condensed consolidated balance sheet as of June 30,
1996 includes the historical financial position of the Company as of June 30,
1996 and gives effect to the offering as if it had occurred at June 30, 1996.
 
     The pro forma information does not purport to be indicative of actual
results that would have been achieved if the US Dental and AHP acquisitions, the
Company's initial public offering that occurred in September 1995 or the
issuance of the Common Stock offered hereby actually had been effective as of
the dates indicated or the results that may be obtained in the future. The pro
forma condensed consolidated financial statements should be read in conjunction
with "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the respective historical consolidated financial statements of
the Company, US Dental and AHP and the related notes thereto included elsewhere
in this Prospectus.

                 INTRODUCTION TO UNAUDITED PRO FORMA CONDENSED
                         COMBINED FINANCIAL STATEMENTS
 
     The accompanying unaudited pro forma condensed combined financial
statements reflect the consolidated financial position of the Company at June
30, 1996 and the results of its consolidated operations for the year ended
December 31, 1995 and the six months ended June 30, 1996, after giving pro forma
effect to: (i) the US Dental and AHP acquisitions; (ii) the offering of Common
Stock pursuant to this Prospectus; and (iii) the proposed Pending Acquisitions.
The unaudited pro forma condensed combined statement of operations for the year
ended December 31, 1995 includes: (i) the historical results of operations of
the Company for the year ended December 31, 1995; (ii) the historical results of
operations of US Dental for the ten months ended October 31, 1995; (iii) the
historical results of operations of AHP and the Pending Acquisitions, except

includes: (i) the historical results of operations of the Company for the six
months ended June 30, 1996; (ii) the historical results of operations of AHP for

     The unaudited pro forma condensed combined statements of operations have
been prepared as if the US Dental and AHP acquisitions, the Pending Acquisitions
and the offering of Common Stock contemplated hereby had occurred on January 1,
1995. The unaudited pro forma condensed combined balance sheet gives effect to
the Pending Acquisitions and this offering as if such transactions had occurred
at June 30, 1996. See "Pending and Recent Acquisitions."
 
     The pro forma condensed combined information gives effect to the US Dental
and AHP acquisitions and the Pending Acquisitions using the purchase method of
accounting. The assumptions and adjustments are described in the Notes to the
Unaudited Pro Forma Condensed Combined Financial Statements.
 
     The pro forma condensed combined information does not purport to be
indicative of actual results that would have been achieved if the US Dental and
AHP acquisitions or the Pending Acquisitions or the issuance of the Common Stock
offered hereby had been effective as of the dates indicated or of the results
that may be obtained in the future. The pro forma condensed combined financial
statements should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the respective
historical consolidated financial statements of the Company, US Dental, AHP and
the Pending Acquisitions and the related notes thereto included elsewhere in
this Prospectus.

                          NOTES TO UNAUDITED PRO FORMA
                    CONDENSED COMBINED FINANCIAL STATEMENTS
 
(a)  See the Introduction to Unaudited Pro Forma Condensed Consolidated 
     Financial Statements.
 
(b)  Sales and marketing & general and administrative expenses have been reduced
     to eliminate salaries and benefits of certain senior officers of OraCare,
     KCDC and UICI Dental Companies, since it is anticipated that certain
     officers will not continue with the Company once the acquisitions are
     complete.
 
(c)  Reflects: (i) the amortization of goodwill related to the acquisitions of
     OraCare, KCDC and UICI ($1,313 in the year ended December 31, 1995 and $656
     in the six months ended June 30, 1996) as amortized over 40 years; and (ii)
     the amortization of the value of the non-competition agreements entered
     into in connection with the acquisitions ($342 in the year ended December
     31, 1995 and $171 in the six months ended June 30, 1996) as amortized over
     36 months. The Company intends to apply the same purchase price allocation
     concepts as used in previous acquisitions as described in Note 2 to the
     Company's Consolidated Financial Statements.
 
(d)  Reflects the income tax effect (assuming a marginal tax rate of 34.0%) of
     the business combination adjustments described in notes (b), (c) and (g)
     herein.
 
(e)  Net income per common share is calculated by dividing pro forma as adjusted
     combined net income by the weighted average number of common shares
     outstanding. Such pro forma as adjusted combined net income reflects: (i)
     with respect to the year ended December 31, 1995, the impact of the pro
     forma adjustments and offering adjustments described in the Unaudited Pro
     Forma Condensed Consolidated Financial Statements and the Notes thereto and
     (ii) with respect to the six months ended June 30, 1996, the pro forma
     adjustments and offering adjustments.
 
(f)  Weighted average number of common shares outstanding is calculated based
     upon the relevant weighted average common shares outstanding and the
     options and warrants outstanding (using the treasury stock method),
     including the Common Stock to be issued pursuant to this offering, for each
     calculation presented.
 
(g)  Reflects the elimination of the interest expense on the indebtedness 
     related to the OraCare, KCDC and UICI acquisitions as a result of the 
     repayment in  full of the indebtedness with the Company's net proceeds 
     from this offering.
 
(h)  Reflects the payment of the purchase price for the acquisitions of OraCare
     of $30,500, KCDC of $12,500 and UICI Dental Companies of $12,750 plus the
     costs of the acquisitions.
 
(i)  Reflects estimated purchase price adjustments for obsolete fixed assets.
 
(j)  Reflects purchase price adjustment for estimated unrecorded liabilities.
 
(k)  Reflects the payment of outstanding indebtedness of OraCare, KCDC and UICI
     Dental Companies with the net proceeds from the offering.
 
(l)  Reflects assumed adjustments based upon a preliminary purchase price
     allocation for the OraCare, KCDC and UICI acquisitions including the use of
     a portion of cash remaining from the public offering of Common Stock
     pursuant to this Prospectus to purchase OraCare, KCDC and UICI Dental
     Companies, the allocation of the purchase price over the fair value of the
     net tangible assets acquired, the increase in UDC's indebtedness for the
     consulting and non-competition agreements related to the OraCare, KCDC and
     UICI Dental Companies acquisitions ($1,025), payment of their outstanding
     indebtedness ($1,276 of current and $1,617 of long term debt) and the
     elimination of the acquisitions stockholders' equity. The Company intends
     to apply the same purchase price allocation concepts as used in past
     acquisitions as described in Note 2 to the Company's Consolidated Financial
     Statements.
 
(m)  Reflects the allocation to intangible assets, including goodwill, of the
     excess of the purchase price over the fair value of the net assets acquired
     for the acquisitions of OraCare, KCDC and UICI Dental Companies.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Under Section 145 of the Delaware General Corporation Law ("Delaware Law"),
the Company has broad powers to indemnify its directors and officers against
liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Company's Bylaws (the "Bylaws") filed as Exhibit 3.02 hereto
provide that the Company shall indemnify its directors and officers to the full
extent permitted by Delaware Law. The Bylaws also provide that rights conferred
under such Bylaws shall not be deemed to be exclusive of any other right such
persons may have or acquire under any statute, agreement, vote of stockholders
or disinterested directors, or under the Certificate of Incorporation, the
Bylaws or otherwise.
 
     The Certificate of Incorporation provides that, pursuant to Delaware Law,
the directors of the Company shall not be liable for monetary damages for breach
of the directors' fiduciary duty of care to the Company and its stockholders.
This provision in the Certificate of Incorporation does not eliminate the duty
of care, and in appropriate circumstances equitable remedies such as injunctive
or other forms of non-monetary relief will remain available under Delaware Law.
In addition, each director will continue to be subject to liability for breach
of the director's duty of loyalty to the Company for acts or omissions not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
unlawful under Delaware Law. The provision also does not affect a director's
responsibilities under any other law, such as the Federal securities laws or
state or federal environmental laws.
 
     The form of Underwriting Agreement filed as Exhibit 1.01 hereto provides
for indemnification by the Underwriters of the Company and its officers and
directors, and by the Company of the Underwriters, for certain liabilities
arising under the Securities Act or otherwise.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     The following is a summary of transactions by the Company during the last
three years preceding the date hereof involving sales of the Company's
securities that were not registered under the Securities Act.
 
     (1) From time to time during the three years preceding the date hereof, the
Company granted stock options to purchase Common Stock pursuant to the Company's
1989 Stock Option Plan, as amended, and the
 
                                      II-1
<PAGE>   125
 
Company's 1995 Stock Option Plan, as amended, and an incentive stock option plan
previously maintained by the Company to certain directors, officers and
employees of the Company. During the three year period referred to above, the
Company issued an aggregate of 472,000 shares of Common Stock to directors,
officers and employees upon the exercise of options issued under the Stock
Option Plans of the Company at exercise prices ranging from $1.25 to $4.00 per
share (as adjusted for the stock split described in Note (4) below).
 
     (2) In December 1993 and April 1995, the Company issued 463,976 shares and
two shares of Common Stock respectively, upon the conversion of shares of 6%
Cumulative Convertible Preferred Stock at a conversion price of $1.37 per share
(as adjusted for the stock split described in Note (4) below).
 
     (3) In January 1995, the Company sold to Mark E. Pape, Senior Vice
President, Chief Financial Officer, Secretary and Treasurer of the Company,
40,000 warrants to purchase an aggregate of 40,000 shares of Common Stock at a
purchase price of $6.00 per share (as adjusted for the stock split described in
Note (4) below). The purchase price for the warrants was $2.00 per warrant (as
adjusted for the stock split described in Note (4) below).
 
     (4) On July 17, 1995, the Company declared a two-for-one stock split that
was effected as a stock dividend pursuant to which each stockholder was issued
one additional share of Common Stock for each outstanding share of Common Stock
owned by such stockholder.
 
     The sales and issuances of securities in the above transactions were deemed
to be exempt from registration under the Securities Act either because they do
not involve a "sale" of securities or by virtue of Section 4(2) thereof as
transactions not involving a public offering. Appropriate legends are affixed to
the stock certificates, stock options or warrants issued in such transactions.
All recipients either received adequate information about the Company or had
access, through employment or other relationships, to such information.

     (B) FINANCIAL STATEMENT SCHEDULES.
 
     All schedules have been omitted since the required information is not
present in amounts sufficient to require submission of the schedule, or because
the information required is included in the Consolidated Financial Statements or
Notes thereto.
 
ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that:
 
     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Company pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
                                      II-6
<PAGE>   130
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, or controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

DALLAS, TEXAS  75240

LADIES AND GENTLEMEN:

         As set forth in the Registration Statement on Form S-1 (the
"Registration Statement"), filed by United Dental Care, Inc., a Delaware
corporation (the "Company"), under the Securities Act of 1933, as amended (the
"Act"), on September 20, 1996, relating to the sale of up to 2,300,000 shares
(the "Shares") of Common Stock, $.10 par value per share, of the Company
("Common Stock"), certain legal matters in connection with the Shares are being
passed upon for the Company by this Firm.  At your request, this opinion is
being furnished to the Company for filing as Exhibit 5.01 to the Registration
Statement.

         We have acted as counsel to the Company in connection with the
registration by the Company of the proposed sale of the Shares by the Company
and a selling stockholder as set forth in the Registration Statement.  In such
capacity, we have examined the Certificate of Incorporation and Bylaws of the
Company, each as amended to the date hereof, and the originals, or copies,
certified or otherwise identified to our satisfaction, of corporate records of
the Company, certificates of public officials, certificates of representatives
of the Company, statutes and other relevant records, instruments and documents
as a basis for the opinions hereinafter expressed.  In giving such opinions, we
have relied upon certificates of officers of the Company with respect to the
accuracy of the material factual matters contained in such documents examined
by us.

         Based upon our examination as aforesaid, we are of the opinion that:

         1.      The Company is a corporation incorporated, existing and in
                 good standing under the laws of the State of Delaware.

         2.      The Shares, when paid for and issued or transferred in the
                 offering pursuant to the Registration Statement,

                 after it has been declared effective by the Securities and
                 Exchange Commission, will be legally issued, fully paid and
                 non-assessable shares of Common Stock of the Company.

         The opinions set forth above are limited to the General Corporation
Law of the State of Delaware and applicable federal law as in effect on the
date hereof.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name in the Registration Statement
under the caption "Legal Matters."

                                        Very truly yours,

                                        /s/ Strasburger & Price, L.L.P.

thereon, or, if so demanded by NationsBank, upon the occurrence of an Event of
Default (defined below) will pay to NationsBank in advance the amount required
to pay the same; and (ii) in the case of each time instrument, Applicant will
pay to NationsBank, at the address specified by NationsBank to Applicant, in
United States currency, the amount thereof, on demand but in any event not

which are payable in currency other than United States currency: (i) in the
case of each sight instrument, Applicant will reimburse NationsBank, at the
address specified by NationsBank to Applicant, on demand, in United States 
currency, the equivalent of the amount paid under the instrument at

(ii) an amount in United States currency equivalent to the estimated cost to

provided that upon the actual settlement of NationsBank's obligation, however

4. CLEAN ADVANCES.      

If the Application requests inclusion in the Credit of any provision for clean
advances to the Beneficiary. NationsBank may place in the Credit such a
provision in that respect as NationsBank may deem appropriate, under which any
bank entitled to negotiate drafts under the Credit, acting in its discretion in
each instance and upon the request and receipt in writing from the Beneficiary,
may make one or more clean advances at any time on or prior to the date by
which drafts are to be negotiated under the Credit. The aggregate of such
advances shall in no event be more than the amount specified in the Application
for clean advances, and whether or not specified therein in no event shall any
such advance exceed the amount remaining available under the Credit at the time
of the advance. While it is expected by Applicant that each such advance will
be repaid by the Beneficiary to the bank that made the advance from the
proceeds of any drafts drawn under the Credit, should any such advance not be
thus repaid. Applicant will on demand pay NationsBank the amounts thereof as if
such advances were evidenced by drafts drawn under the Credit. It is understood
that neither NationsBank nor any bank which may make such advances shall be
obligated to inquire into the use that may be made thereof by the Beneficiary
and that NationsBank and each such bank shall be without liability for any
wrongful use that may be made by the Beneficiary of any funds so advanced.

5. UNIFORM CUSTOMS AND PRACTICE.

the date of issue of the Credit by the International Chamber of Commerce (the

incorporated herein and shall apply to the Credit. Unless expressly provided
otherwise in the Credit, in the event any provision of the UCP is or is
construed to vary from or be in conflict with the laws of the United States of
America or any state thereof, as from time to time amended and in force, the
UCP shall prevail to the extent permitted by applicable law.

time require.

to endorse any check in the name of Applicant received in payment of any loss
or adjustment.

8.  DEFAULT.

a) In the event of the happening of any one or more of the following events (any
such event being hereinafter called an "Event of Default"), namely: (i) the
nonpayment of any obligations of Applicant to NationsBank (under the Agreement
or otherwise), or to any other person or entity, now or hereinafter existing,

or covenant of the Agreement, or (iii) the dissolution or termination of
existence of Applicant, or (iv) the institution by or against Applicant of any
proceeding seeking to adjudicate Applicant a bankrupt or insolvent, or seeking
liquidation, winding up, reorganization, arrangement, adjustment, protection,
relief, or composition of Applicant or its debts under any law relating to
bankruptcy, insolvency or reorganization or relief of debtors, or seeking the
entry of an order for relief or the appointment of a receiver, trustee,
custodian, or other similar official for Applicant or for any substantial part
of its property, or (v) any seizure, vesting or intervention by or under
authority of a government by which the management of Applicant is displaced or
its authority in the control of its business is curtailed, or (vi) the
attachment of or restraint as to any funds or other property which may be in, or
come into, the possession or control of NationsBank, or of any third party
acting on NationsBank's behalf, for the account or benefit of Applicant, or the
issuance of any order of court or other legal process against the same, or (vii)
the occurrence of any of the above events with respect to any person or entity
which has guaranteed any obligations of Applicant to NationsBank (under the
Agreement or otherwise); then, or at any time after the happening of such
event, the amount of the Credit, as well as any and all other obligations of
Applicant under the Agreement, shall, at NationsBank's option, and whether or
not otherwise then due and payable, become due and payable immediately without
demand upon or notice to Applicant.

b) Upon the occurrence and during the continuance of any Event of Default,
NationsBank is hereby authorized to set off and apply any and all deposits
general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by NationsBank or any subsidiary or
affiliate of NationsBank to or for the credit or the account of Applicant
against any and all of Applicant's obligations to NationsBank under the
Agreement, irrespective of whether or not NationsBank shall have made any
demand under the Agreement and although such deposits, indebtedness or
obligations may be unmatured or contingent.  NationsBank's rights under this
Section 8(b) are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which NationsBank may have.

9.  SECURITY.

a) As collateral for the payment of any and all obligations of Applicant to
NationsBank under the Agreement, Applicant hereby grants to NationsBank a
security interest in (i) any and all documents of title, policies or
certificates of insurance and other documents accompanying or related to
instruments drawn under the Credit, and any and all other property shipped
under or in connection with the Credit or in any way related thereto or to any
of the instruments drawn thereunder (whether or not such documents or property
are released to or upon the order of Applicant in trust or otherwise) and (ii)
any and all proceeds and products of the foregoing.  Also to secure the payment
of any and all obligations of Applicant under the Agreement, NationsBank shall
be subrogated to the rights (but shall have none of the obligations) of
Applicant in respect of any transaction to which the Credit relates.  Insofar
as any property which may be held by NationsBank, or for NationsBank's account,
as collateral hereunder may be released to or upon the order of Applicant,
Applicant hereby acknowledges that such delivery of property is in trust
pending satisfaction of Applicant's payment obligations to NationsBank, and
hereby agrees to execute and/or file such receipts, agreements, forms or other
documents as NationsBank may request to further evidence NationsBank's
interests in such property, it being understood that NationsBank's rights as
specified therein shall be in furtherance of and in addition to (but not in
limitation of) NationsBank's rights hereunder.  NationsBank is hereby
authorized, at its option at any time and with or without notice to Applicant,
to transfer to or register in its name or the name of any NationsBank's
nominees all or any part of the property subject to any of the security
interests granted under or contemplated by the Agreement.  NationsBank is also
authorized, at its option, to file financing statements without the signature
of Applicant with respect to all or any part of such property.  Applicant will
pay the cost of any such filing and, upon NationsBank's request, sign such
instruments, documents or other papers, and take such other action, as
NationsBank may reasonably require to perfect such security interests.

b) If any Event of Default shall have occurred and be continuing, NationsBank
may exercise in respect of the property subject to any of the security
interests granted under or contemplated by the Agreement all the rights and
remedies of a secured party on default under the applicable Uniform Commercial
Code or any other applicable law, and also may, without notice except as
specified below, sell such property or any part thereof in one or more parcels
at public or private sale, at any NationsBank office or elsewhere, for cash,
on credit or for future delivery, and upon such other terms as NationsBank may
deem commercially reasonable.  To the extent notice of sale of such property
shall be required by law, reasonable notification shall be satisfied by written
notice mailed or delivered to Applicant at the address specified above at least
ten business days prior to the date of public sale or prior to the date after
which private sale is to be made.  Applicant will pay to NationsBank on demand
all costs and expenses (including, without limitation, reasonable attorney's
fees and legal expenses) related or incidental to the custody, preservation or
sale of, or collection from, or other realization upon, any of such property
or related or incidental to the establishment, preservation or enforcement of
NationsBank's rights in respect of any such property. In the event of sale
of, collection from, or other realization upon all or any part of such
property,  NationsBank may, in its discretion, hold the proceeds thereof as
additional collateral hereunder or then or at any time thereafter apply the
proceeds thereof to the payment of such of the costs and expenses referred to
above and such of the obligations of Applicant under the Agreement, whether or
not then due, as NationsBank may determine in its discretion, any surplus to be
paid over to Applicant or to whomever may be lawfully entitled to receive such
surplus.

10.  INDEMNITY.

Applicant will indemnify and hold NationsBank (such term to include for purposes
of this paragraph NationsBank's affiliates and its and its affiliates'
officers, directors, employees and agents) harmless from and against (i) all
loss or damage arising out of NationsBank's issuance of, or any other action
taken by NationsBank in connection with, the Credit other than loss or damage
resulting from the gross negligence or willful misconduct of the party seeking
indemnification, and (ii) all costs and expenses (including reasonable
attorney's fees and legal expenses) of all claims or legal proceedings arising
out of NationsBank's issuance of the Credit or incident to the collection of
amounts owed by Applicant hereunder or the enforcement of NationsBank's rights
hereunder, including, without limitation, legal proceedings related to any
court order, injunction, or other process or decree restraining or seeking to
restrain NationsBank from paying any amount under the Credit.  Additionally,
Applicant will indemnify and hold NationsBank harmless from and against all
claims, losses, damages, suits, costs or expenses arising out of Applicant's
failure to timely procure licenses or comply with applicable laws, regulations
or rules, or any other conduct or failure of Applicant relating to or affecting
the Credit.

11. EFFECT OF WAIVERS.

No delay, extension of time, renewal, compromise or other indulgence which may
occur or be granted by NationsBank shall impair NationsBank's rights or powers
hereunder. NationsBank shall not be deemed to have waived any of its rights
hereunder, unless NationsBank or its authorized agent shall have signed such
waiver in writing.

12. FINANCIAL INSTITUTION APPLICANT

If Applicant or Co-Applicant is a financial institution (the "Financial
Institution") the Financial Institution hereby requests the issuance of the
Credit for its customer (the "Customer"), who has also executed the Application 
as Applicant or Co-Applicant. In consideration of such issuance and as a
direct and primary obligation, the Financial Institution agrees to pay to
NationsBank all amounts owed by the Customer under the Agreement when due, and
to pay to NationsBank its fees and expenses according to its fee schedule from
time to time in effect. The Financial Institution hereby grants to NationsBank
a security interest in all of the property in which the Customer has heretofore
granted or may hereafter grant to the Financial Institution a security interest
to secure the obligations of the Customer to the Financial Institution arising
out of the execution of the Application by the Financial Institution.

13. MISCELLANEOUS.

(a) Any notice from NationsBank to Applicant shall be deemed given when given
in accordance with the Addendum.

(b) Each provision of the Agreement shall be interpreted in such manner as to
be effective and valid under applicable law but if any provision of the
Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of the Agreement.

(c) If any law, treaty, regulation or the interpretation thereof by any court
or administrative or governmental authority shall impose, modify or deem
applicable any capital, reserve, insurance premium or similar requirement
against letters of credit issued by NationsBank and the result thereof shall be
to increase the cost to NationsBank of making any payment under or issuing or
maintaining the Credit or to reduce the yield to NationsBank in connection with
the Credit or the Agreement, then, on demand, Applicant will pay to
NationsBank, from time to time, such additional amounts as NationsBank may in
good faith determine to be necessary to compensate NationsBank for such
increased cost or reduced yield.

(d) Any and all payments made to NationsBank hereunder shall be made free and
clear of and without deduction for any present or future taxes, levies,
imposts, deductions, charges, or withholdings, and all liabilities with respect
thereto, excluding taxes imposed on net income and all income and franchise
taxes of the United States and any political subdivisions thereof (such
nonexcluded taxes being herein called "Taxes"). If Applicant shall be required
by law to deduct any Taxes from or in respect of any sum payable hereunder, (i)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 13(d)), NationsBank shall receive an amount equal to the sum
NationsBank would have received had no such deductions been made, (ii) 
Applicant shall make such deductions, and (iii) Applicant shall pay the full
amount deducted to the relevant authority in accordance with applicable law. 
Applicant will indemnify NationsBank for the full amount of Taxes (including,
without limitation, any Taxes imposed by any jurisdiction on amounts payable
under this Section 13(d)) paid by NationsBank and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes were correctly or legally asserted. This 
indemnification shall be made within 30 days from the date NationsBank makes 
written demand therefor. Within 30 days after the date of any payment of 
Taxes, Applicant will furnish to NationsBank the original or a certified copy 
of a receipt evidencing payment thereof.

(e) The Agreement shall be binding upon Applicant, its successors and assigns,
and shall inure to the benefit of NationsBank, its successors, transferees and
assigns; provided that any assignment by Applicant of any of its rights or
obligations under the Agreement without the prior written consent of
NationsBank shall be void.

(g) Any action, inaction, waiver or omission taken or suffered by NationsBank
or by any of NationsBank's correspondents under or in connection with the
Credit or any related instruments, services or property, if in good faith and
in conformity with foreign or domestic laws, regulations or customs applicable
thereto, shall be binding upon Applicant and shall not place NationsBank or any
of NationsBank's correspondents under any resulting liability to Applicant.
Without limiting the generality of the foregoing, NationsBank and
NationsBank's correspondents may act in reliance upon any written, oral,
telephonic, telegraphic, facsimile or other request or notice, believed in good
faith to have been authorized, whether or not given or signed by an authorized
person and any such written, oral, telephonic, telegraphic, facsimile or other
request or notice, shall be binding on Applicant.

(h) Except as provided in Section 13(g), no term or provision of the Agreement
can be changed orally, and no executory agreement shall be effective to modify
or to discharge the Agreement unless such executory agreement is in writing and
signed by NationsBank. Applicant's payment and indemnity obligations under the
Agreement shall survive payment under or expiration of the Credit or
termination of this Agreement.

14. JURISDICTION AND WAIVER.

Applicant hereby irrevocably submits to the non-exclusive jurisdiction of any
State or Federal court sitting in the city, county, or district in Dallas
County Texas over any action or proceeding arising out of or relating to the
Agreement, and Applicant hereby irrevocably agrees that all claims in respect
to such action or proceeding may be heard and determined in such State or
Federal court. APPLICANT HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF
SUCH ACTION OR PROCEEDING AND THE LACK OF PERSONAL JURISDICTION. TO THE FULLEST 
EXTENT IT MAY LAWFULLY AND EFFECTIVELY DO SO, EACH OF APPLICANT AND NATIONSBANK
WAIVES THE RIGHT TO TRIAL BY JURY. Applicant irrevocably consents to the
service of any and all process in any such action or proceeding by the mailing
of copies of such process to Applicant at the last business address furnished
by Applicant to NationsBank. Applicant agrees that a final judgment in any such 
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing, however, in this Section 14, shall affect the right of NationsBank to
serve legal process in any other manner permitted by law or affect the right of
NationsBank to bring any action or proceeding against Applicant or its property
in the courts of any other jurisdiction. Moreover, to the extent that Applicant
has or hereafter may acquire any immunity from jurisdiction of any court or
from any legal process (whether through service or notice, attachment prior to
judgment, attachment in aid of execution or otherwise) with respect to itself
or its property. Applicant hereby irrevocably waives such immunity in respect
of its obligations under the Agreement.

15. FINAL AGREEMENT.

EXCEPT AS PROVIDED IN SECTION 13(g), THIS WRITTEN AGREEMENT REPRESENTS THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE
NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                                   ADDENDUM
                                      TO
                             AMENDED AND RESTATED
                          APPLICATION AND AGREEMENT
                         FOR STANDBY LETTER OF CREDIT

1.    Amendment and Restatement. This Agreement is in amendment and
      restatement of that certain Application and Agreement for Standby
      Letter of Credit dated September 16, 1994, executed by Applicant in favor
      of NationsBank.

2.    Letter of Credit Fees. Applicant shall pay to NationsBank a fee
      determined at the rate per annum which shall be equal to one percent (1%) 
      (computed on the basis of actual number of days elapsed in a year
      consisting of 365 or 366 days, as applicable) on the face amount remaining
      to be drawn on the Letter of Credit as of the beginning of each quarter
      during the term of such Letter of Credit. Such letter of credit fee shall
      be payable quarterly in advance commencing on the date hereof, and
      thereafter, on the fifteenth (15th) day of each December, March, June and
      September until termination or cancellation of this Letter of Credit.

      Notwithstanding the foregoing, for each day on which there shall exist
      and be continuing an Event of Default, the rate per annum at which the
      letter of credit fee referred to in (b) above shall accrue shall be one
      and one-half percent (1.5%), instead of one percent (1%), per annum.

      Applicant acknowledges and agrees that the letter of credit fees are
      intended as reasonable compensation to NationsBank for issuing the
      Letter of Credit and for making available amounts for draw(s) thereunder
      as described herein and therein and for no other purpose. All fees
      referred to in this Section shall be payable to NationsBank in federal or
      other immediately available funds at NationsBank's address set forth
      herein.

3.    Notwithstanding anything contained to the contrary herein:

                (a) Applicant shall reimburse NationsBank for each draw
      (whether partial or full) under the Letter of Credit immediately after
      the payment of such draw by NationsBank; and

                (b) such reimbursement obligations shall bear interest at a
      rate per annum which shall from day to day be equal to (i) from (and
      including) the date of the payment of such draw by NationsBank until the
      third (3rd) day following the date on which NationsBank shall notify
      Applicant of such drawing, the lesser of the (A) maximum rate allowed by
      applicable law and (B) the variable rate of interest established from
      time to time by NationsBank as its general reference rate of interest
      (which rate of interest may not be the lowest rate charged by NationsBank
      on similar loans) plus one percent (1%), and (ii) from (and including)
      such third (3rd) day until (but excluding) the date such reimbursement
      obligations are paid, the maximum lawful rate.

4.    Payment of Reimbursement Obligations.  Applicant agrees to pay to
      NationsBank all reimbursement obligations, interest and other amounts
      payable to NationsBank under or in connection with the Letter of Credit
      immediately when due, irrespective of any claim, setoff, defense or
      other right which Applicant may have at any time against NationsBank or
      any other person. Each such payment shall be made to NationsBank in
      Federal or other immediately available funds at the NationsBank's address
      set forth below.

5.      INDEMNIFICATION; EXONERATION.        

                 (a)      INDEMNIFICATION.  In addition to amounts payable as
        elsewhere provided herein, APPLICANT HEREBY AGREES TO PROTECT,
        INDEMNIFY, PAY AND SAVE NATIONSBANK AND ITS DIRECTORS, OFFICERS, AGENTS,
        ATTORNEYS AND EMPLOYEES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS,
        DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES AND EXPENSES
        (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH NATIONSBANK MAY INCUR OR BE
        SUBJECT TO as a consequence, direct or indirect, of (i) Applicant's
        failure to make payments to NationsBank as required hereunder, (ii) the
        issuance of any Letter of Credit other than as a result of the gross
        negligence or willful misconduct of  NationsBank, as determined by an
        arbitrator or arbitrators, or a court of competent jurisdiction, as
        appropriate, (BUT INCLUDING AS A RESULT OF THE ORDINARY NEGLIGENCE OF
        NATIONSBANK); or (iii) the failure of NationsBank to honor a drawing
        under a Letter of  Credit as a result of any act or omission, whether
        rightful or wrongful, of any present or future de jure or de facto
        governmental authority.

                 (b)      Assumption of  Risk by Applicant.  As between

        Applicant and NationsBank, Applicant assumes all risks of the acts and
        omissions of, or misuse of the Letter of  Credit by, the beneficiary of
        the Letter of Credit.  In furtherance and not in limitation of the
        foregoing, NationsBank shall not be responsible:

                          (i)     for the form, validity, sufficiency,
        accuracy, genuineness or legal effect of any document submitted by any
        party in connection with the application for and issuance of  the Letter
        of Credit, even if it should in fact prove to be in any or all respects
        invalid, insufficient, inaccurate, fraudulent or forged; and

                          (ii)    for the validity or sufficiency of  any
        instrument transferring or assigning or purporting to transfer or assign
        the 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; and

                          (iii)   so long as the documentation delivered to
        NationsBank conforms on its face to the requirements of  the applicable
        Letter of Credit, for failure to the beneficiary  of the Letter of
        Credit to comply duly with conditions required in order to draw upon
        such Letter of Credit; and

                          (iv)    for errors, omissions, interruptions or
        delays in transmission or delivery of any messages, by mail, cable,
        telegraph, telex or otherwise, whether or not they be in cipher, except
        for errors caused by the gross negligence or willful misconduct of
        NationsBank; and

                          (v)     for errors in interpretation of technical
        terms, except for errors caused by the gross negligence or willful

2. PROMISE TO PAY.

(a) As to instruments drawn under or purporting to be drawn under the Credit,
which are payable in United States currency: (i) in the case of each sight
instrument, Applicant will reimburse NationsBank, at the address specified by 
NationsBank to Applicant, on demand, in United States currency, the amount paid 
thereon, or, if so demanded by NationsBank, upon the occurrence of an Event of
Default (defined below) will pay to NationsBank in advance the amount required
to pay the same; and (ii) in the case of each time instrument, Applicant will
pay to NationsBank, at the address specified by NationsBank to Applicant, in
United States currency, the amount thereof; on demand but in any event not
later than one business day prior to maturity of such time instrument at the
place specified by the Credit for payment.

(b) As to instruments drawn under or purporting to be drawn under the Credit,
which are payable in currency other than United States currency: (i) in the case
of each sight instrument, Applicant will reimburse NationsBank, at the address
specified by NationsBank to Applicant, on demand, in United States currency, the
equivalent of the amount paid under the instrument at NationsBank's then current
selling rate of exchange for teletransmission to the place of payment in the
currency in which such instrument is payable, or, if so demanded by NationsBank,
will pay to NationsBank, in advance, in United States currency, the equivalent
of the amount required to pay the same; and (ii) in the case of each time
instrument. Applicant will pay to NationsBank, at the address specified by
NationsBank to Applicant, on demand but in any event sufficiently in advance of
maturity of such time instrument to enable NationsBank to arrange for cover to
reach the place of payment not later than three business days prior to maturity,
the equivalent of the time instrument in United States currency at NationsBank's
then current selling rate of exchange for teletransmission to the place of
payment in the currency in which such instrument is payable. If for any cause
whatsoever there exists at the time in question no rate of exchange generally
current for effecting transfers as above described, or such currency is not
available for purchase by NationsBank, Applicant agrees to pay NationsBank on
demand, at NationsBank's election, (i) an amount in United States currency
equivalent to the actual cost to NationsBank of settlement of NationsBank's
obligation to the holder of the instrument or other person, however and whenever
such settlement shall be made by NationsBank, or (ii) an amount in United States
currency equivalent to the estimated cost to NationsBank, as projected by
NationsBank, of the future settlement of NationsBank's obligation to the holder
of the instrument or other person, provided that upon the actual settlement of
NationsBank's obligation, however and whenever occurring, NationsBank shall
reimburse Applicant or Applicant shall pay to NationsBank, as the case may be,
an amount in United States currency equal to the difference between the initial
estimated payment by Applicant to NationsBank and the actual settlement amount
paid by NationsBank.

(c) NationsBank may accept or pay any instrument presented to it, regardless of
when drawn and whether or not negotiated, if such instrument, the other
required documents and any transmittal advice are dated on or before the
expiration date of the Credit, and NationsBank may honor, as complying with the
terms of the Credit and of the Agreement, any instruments or other documents
otherwise in order signed or issued by any person who is, or is in good faith
believed by NationsBank to be, an administrator, executor, trustee in
bankruptcy, debtor in possession, conservator, assignee for the benefit of
creditors, liquidator, receiver or other legal representative or successor by
operation of law of the party authorized under the Credit to draw or issue such
instruments or other documents.

3. PROMISE TO PAY INTEREST AND FEES.

(a) Applicant will pay NationsBank, on demand: (i) NationsBank's fees set forth
in the Addendum, (ii) unless expressly provided otherwise in the Application,
all charges and expenses paid or incurred by NationsBank in connection with the
Credit, including, without limitation, reasonable attorneys' fees for the
enforcement of any rights hereunder, and (iii) interest on any amounts due by
Applicant to NationsBank hereunder from the date due to the date of payment at
the Applicable Interest Rate.

(b) No provision of the Agreement shall require the payment or permit the
collection of interest in excess of the maximum rate permitted by applicable
law.

4. CLEAN ADVANCES.      

If the Application requests inclusion in the Credit of any provision for clean
advances to the Beneficiary. NationsBank may place in the Credit such a
provision in that respect as NationsBank may deem appropriate, under which any
bank entitled to negotiate drafts under the Credit, acting in its discretion in
each instance and upon the request and receipt in writing from the Beneficiary,
may make one or more clean advances at any time on or prior to the date by
which drafts are to be negotiated under the Credit. The aggregate of such
advances shall in no event be more than the amount specified in the Application
for clean advances, and whether or not specified therein in no event shall any
such advance exceed the amount remaining available under the Credit at the time
of the advance. While it is expected by Applicant that each such advance will
be repaid by the Beneficiary to the bank that made the advance from the
proceeds of any drafts drawn under the Credit, should any such advance not be
thus repaid. Applicant will on demand pay NationsBank the amounts thereof as if
such advances were evidenced by drafts drawn under the Credit. It is understood
that neither NationsBank nor any bank which may make such advances shall be
obligated to inquire into the use that may be made thereof by the Beneficiary
and that NationsBank and each such bank shall be without liability for any
wrongful use that may be made by the Beneficiary of any funds so advanced.

5. UNIFORM CUSTOMS AND PRACTICE.

The Uniform Customs and Practice for Documentary Credits, as published as of
the date of issue of the Credit by the International Chamber of Commerce (the
"UCP"), shall in all respects be deemed a part hereof as fully as if
incorporated herein and shall apply to the Credit. Unless expressly provided
otherwise in the Credit, in the event any provision of the UCP is or is
construed to vary from or be in conflict with the laws of the United States of
America or any state thereof, as from time to time amended and in force, the
UCP shall prevail to the extent permitted by applicable law.

performed or the import, export or shipping of property shipped under or
pursuant to or in connection with the Credit, and will comply with all foreign
and domestic laws, rules and regulations now or hereafter applicable to the
transaction related to the Credit or applicable to the execution, delivery and
performance by Applicant of the Agreement.  Applicant further agrees to furnish
to NationsBank such evidence in respect of the above as NationsBank may at any
time require.

7.  INSURANCE.

Applicant shall keep such property as may be the subject of the Credit
adequately covered by insurance in amounts, against risks and with companies
satisfactory to NationsBank.  Applicant hereby irrevocably grants its power of
attorney to NationsBank and any of its officers, with the power of substitution,
to endorse any check in the name of Applicant received in payment of any loss
or adjustment.

8.  DEFAULT.

(a) In the event of the happening of any one or more of the following events
(any such event being hereinafter called an "Event of Default"), namely:  (i)
the nonpayment of any obligations of Applicant to NationsBank (under the
Agreement or otherwise), or to any other person or entity, now or hereinafter
existing, when due, or (ii) the failure of Applicant to perform or observe any
other term or covenant of the Agreement, or (iii) the dissolution or termination
of existence of Applicant, or (iv) the institution by or against Applicant or
any proceeding seeking to adjudicate Applicant a bankrupt or insolvent, or
seeking liquidation, winding up, reorganization, arrangement, adjustment,
protection, relief, or composition of Applicant or its debts under any law
relating to bankruptcy, insolvency or reorganization or relief of debtors, or
seeking the entry of an order for relief or the appointment of a receiver,
trustee, custodian, or other similar official for Applicant or for any
substantial part of its property, or (v) any seizure, vesting or intervention by
or under authority of a government by which the management of Applicant is
displaced or its authority in the control of its business is curtailed, or (vi)
the attachment of or restraint as to any funds or other property which may be
in, or come into, the possession or control of NationsBank, or of any third
party acting on NationsBank's behalf, for the account or benefit of Applicant,
or the issuance of any order of court or other legal process against the same,
or (vii) the occurrence of any of the above events with respect to any person or
entity which has guaranteed any obligations of Applicant to NationsBank (under
the Agreement or otherwise); then, or at any time after the happening of such
event, the amount of the Credit, as well as any and all other obligations of
Applicant under the Agreement, shall, at NationsBank's option, and whether or
not otherwise then due and payable, become due and payable immediately without
demand upon or notice to Applicant.

(b) Upon the occurrence and during the continuance of any Event of Default,
NationsBank is hereby authorized to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by NationsBank or any subsidiary or
affiliate of NationsBank to or for the credit or the account of Applicant
against any and all of Applicant's obligations to NationsBank under the
Agreement, irrespective of whether or not NationsBank shall have made any
demand under the Agreement and although such deposits, indebtedness or
obligations may be unmatured or contingent.  NationsBank's rights under this
Section 8(b) are in addition to other rights and remedies (including, without
limitation, other rights of set-off) which NationsBank may have.

9.  SECURITY.

(a) As collateral for the payment of any and all obligations of Applicant to
NationsBank under the Agreement, Applicant hereby grants to NationsBank a
security interest in (i) any and all documents of title, policies or
certificates of insurance and other documents accompanying or related to
instruments drawn under the Credit, and any and all other property shipped
under or in connection with the Credit or in any way related thereto or to any
of the instruments drawn thereunder (whether or not such documents or property
are released to or upon the order of Applicant in trust or otherwise) and (ii)
any and all proceeds and products of the foregoing.  Also to secure the payment
of any and all obligations of Applicant under the Agreement, NationsBank shall
be subrogated to the rights (but shall have none of the obligations) of
Applicant in respect of any transaction to which the Credit relates.  Insofar
as any property which may be held by NationsBank, or for NationsBank's account,
as collateral hereunder may be released to or upon the order of Applicant.
Applicant hereby acknowledges that such delivery of property is in trust
pending satisfaction of Applicant's payment obligations to NationsBank, and
hereby agrees to execute and/or file such receipts, agreements, forms or other
documents as NationsBank may request to further evidence NationsBank's
interests in such property, it being understood that NationsBank's rights as
specified therein shall be in furtherance of and in addition to (but not in
limitation of) NationsBank's rights hereunder.  NationsBank is hereby
authorized, at its option at any time and with or without notice to Applicant,
to transfer to or register in its name or the name of any NationsBank's
nominees all or any part of the property subject to any of  the security
interests granted under or contemplated by the Agreement.  NationsBank is also
authorized, at its option, to file financing statements without the signature
of Applicant with respect to all or any part of such property.  Applicant will
pay the cost of any such filing and, upon NationsBank's request, sign such
instruments, documents or other papers, and take such other action, as
NationsBank may reasonably require to perfect such security interests.

(b) If any Event of Default shall have occurred and be continuing, NationsBank
may exercise in respect of the property subject to any of the security
interests granted under or contemplated by the Agreement all the rights and
remedies of a secured party on default under the applicable Uniform Commercial
Code or any other applicable law, and also may, without notice except as
specified below, sell such property or any part thereof in one or more parcels
at public or private sale, at any NationsBank office or elsewhere, for cash,
on credit or for future delivery, and upon such other terms as NationsBank may
deem commercially reasonable.  To the extent notice of sale of such property
shall be required by law, reasonable notification shall be satisfied by written
notice mailed or delivered to Applicant at the address specified about at least
ten business days prior to the date of public sale or prior to the date after
which private sale is to be made.  Applicant will pay to NationsBank on demand
all costs and expenses (including, without limitation, reasonable attorney's
fees and legal expenses) related or incidental to the custody, preservation or
sale of, or collection from, or other realization upon, any of such property
or related or incidental to the establishment, preservation or enforcement of
NationsBank's rights in respect of any such property.  In the event of sale
of, collection from, or other realization upon all or any part of such
property.  NationsBank may, in its discretion, hold the proceeds thereof as
additional collateral hereunder or when or at any time thereafter apply the
proceeds thereof to the payment of such of the costs and expenses referred to
above and such of the obligations of Applicant under the Agreement, whether or
not then due, as NationsBank may determine in its discretion, any surplus to be
paid over to Applicant or to whomever may be lawfully entitled to receive such
surplus.

10.  INDEMNITY.

Applicant will indemnify and hold NationsBank (such term to include for purposes
of this paragraph NationsBank's affiliates and its and its affiliates'
officers, directors, employees and agents) harmless from and against (i) all
loss or damage arising out of NationsBank's issuance of, or any other action
taken by NationsBank in connection with, the Credit other than loss or damage
resulting from the gross negligence or willful misconduct of the party seeking
and modification, and (ii) all costs and expenses (including reasonable
attorney's fees and legal expenses) of all claims or legal proceedings arising
out of NationsBank's issuance of the Credit or incident to the collection of
amounts owed by Applicant hereunder or the enforcement of NationsBank's rights
hereunder, including, without limitation, legal proceedings related to any
court order, injunction, or other process or decree restraining or seeking to
restrain NationsBank from paying any amount under the Credit.  Additionally,
Applicant will indemnify and hold NationsBank harmless from and against all
claims, losses, damages, suits, costs or expenses arising out of Applicant's
failure to timely procure licenses or comply with applicable laws, regulations
or rules, or any other conduct or failure of Applicant relating to or affecting
the Credit.

11. EFFECT OF WAIVERS

No delay, extension of time, renewal, compromise or other indulgence which may
occur or be granted by NationsBank shall impair NationsBank's rights or powers
hereunder. NationsBank shall not be deemed to have waived any of its rights
hereunder, unless NationsBank or its authorized agent shall have signed such
waiver in writing.

12. FINANCIAL INSTITUTION APPLICANT

If Applicant or Co-Applicant is a financial institution (the "Financial
Institution") the Financial Institution hereby requests the issuance of the
Credit for its customer (the "Customer"), who has also executed the Application 
as Applicant or Co-Applicant. In consideration of such issuance and as a
direct and primary obligation, the Financial Institution agrees to pay to
NationsBank all amounts owed by the Customer under the Agreement when due, and
to pay to NationsBank its fees and expenses according to its fee schedule from
time to time in effect. The Financial Institution hereby grants to NationsBank
a security interest in all of the property in which the Customer has heretofore
granted or may hereafter grant to the Financial Institution a security interest
to secure the obligations of the Customer to the Financial Institution arising
out of the execution of the Application by the Financial Institution.

13. MISCELLANEOUS.

(a) Any notice from NationsBank to Applicant shall be deemed given when given
in accordance with the Addendum.

(b) Each provision of the Agreement shall be interpreted in such manner as to
be effective and valid under applicable law but if any provision of the
Agreement shall be prohibited by or invalid under applicable law, such
provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of the Agreement.

(c) If any law, treaty, regulation or the interpretation thereof by any court
or administrative or governmental authority shall impose, modify or deem
applicable any capital, reserve, insurance premium or similar requirement
against letters of credit issued by NationsBank and the result thereof shall be
to increase the cost to NationsBank of making any payment under or issuing or
maintaining the Credit or to reduce the yield to NationsBank in connection with
the Credit or the Agreement, then, on demand, Applicant will pay to
NationsBank, from time to time, such additional amounts as NationsBank may in
good faith determine to be necessary to compensate NationsBank for such
increased cost or reduced yield.


(d) Any and all payments made to NationsBank hereunder shall be made free and
clear of and without deduction for any present or future taxes, levies,
imposts, deductions, charges, or withholdings, and all liabilities with respect
thereto, excluding taxes imposed on net income and all income and franchise
taxes of the United States and any political subdivisions thereof (such
nonexcluded taxes being herein called "Taxes). If Applicant shall be required
by law to deduct any Taxes from or in respect of any sum payable hereunder, (i)
the sum payable shall be increased as may be necessary so that after making all
required deductions (including deductions applicable to additional sums payable
under this Section 13(d)), NationsBank shall receive an amount equal to the sum
NationsBank would have received had no such deductions been made, (ii) 
Applicant shall make such deductions, and (iii) Applicant shall pay the full
amount deducted to the relevant authority in accordance with applicable law. 
Applicant will indemnify NationsBank for the full amount of Taxes (including,
without limitation, any Taxes imposed by any jurisdiction on amounts payable
under this Section 13(d)) paid by NationsBank and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes were correctly or legally asserted. The 
indemnification shall be made within 30 days from the date NationsBank makes 
written demand therefor. Within 30 days after the date of any payment of Taxes, 
Applicant will furnish to NationsBank the original or a certified copy of a
receipt evidencing payment thereof.

(e) The Agreement shall be binding upon Applicant, its successors and assigns,
and shall inure to the benefit of NationsBank, its successors, transferees and
assigns; provided that any assignment by Applicant of any of its rights or
obligations under the Agreement without the prior written consent of
NationsBank shall be void.

(g) Any action, inaction, waiver or omission taken or suffered by NationsBank
or by any of NationsBank's correspondents under or in connection with the
Credit or any related instruments, services or property, if in good faith and
in conformity with foreign or domestic laws, regulations or customs applicable
thereto, shall be binding upon Applicant and shall not place NationsBank or any
of NationsBank's correspondents under any resulting liability to Applicant.
Without limiting the generality of the foregoing, NationsBank and
NationsBank's correspondents may act in reliance upon any written, oral,
telephonic, telegraphic, facsimile or other request or notice, believed in good
faith to have been authorized, whether or not given or signed by an authorized
person and any such written, oral, telephonic, telegraphic, facsimile or other
request or notice, shall be binding on Applicant.

(h) Except as provided in Section 13(g), no term or provision of the Agreement
can be changed orally, and no executory agreement shall be effective to modify
or to discharge the Agreement unless such executory agreement is in writing and
signed by NationsBank. Applicant's payment and indemnity obligations under the
Agreement shall survive payment under or expiration of the Credit or
termination of this Agreement.

14. JURISDICTION AND WAIVER.

Applicant hereby irrevocably submits to the non-exclusive jurisdiction of any
State or Federal court sitting in the city, county, or district in Dallas
County Texas over any action or proceeding arising out of or relating to the
Agreement, and Applicant hereby irrevocably agrees that all claims in respect
to such action or proceeding may be heard and determined in such State or
Federal court. APPLICANT HEREBY IRREVOCABLY WAIVES TO THE FULLEST EXTENT IT MAY
EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF
SUCH ACTION OR PROCEEDING AND THE LACK OF PERSONAL JURISDICTION. TO THE FULLEST 
EXTENT IT MAY LAWFULLY AND EFFECTIVELY DO SO, EACH OF APPLICANT AND NATIONSBANK
WAIVES THE RIGHT TO TRIAL BY JURY. Applicant irrevocably consents to the
service of any and all process in any such action or proceeding by the mailing
of copies of such process to Applicant at the last business address furnished
by Applicant to NationsBank. Applicant agrees that a final judgment in any such 
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing, however, in this Section 14, shall affect the right of NationsBank to
serve legal process in any other manner permitted by law or affect the right of
NationsBank to bring any action or proceeding against Applicant or its property
in the courts of any other jurisdiction. Moreover, to the extent that Applicant
has or hereafter may acquire any immunity from jurisdiction of any court or
from any legal process (whether through service or notice, attachment prior to
judgment, attachment in aid of execution or otherwise) with respect to itself
or its property, Applicant hereby irrevocably waives such immunity in respect
of its obligations under the Agreement.

15. FINAL AGREEMENT.

EXCEPT AS PROVIDED IN SECTION 13(g), THIS WRITTEN AGREEMENT REPRESENTS THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE
NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES.

      Notwithstanding the foregoing, for each day on which there shall exist
      and be continuing an Event of Default, the rate per annum at which the
      letter of credit fee referred to in (b) above shall accrue shall be one
      and one-half percent (1.5%), instead of one percent (1%), per annum.

      Applicant acknowledges and agrees that the letter of credit fees are
      intended as reasonable compensation to NationsBank for issuing the
      Letter of Credit and for making available amounts for draw(s) thereunder
      as described herein and therein and for no other purpose. All fees
      referred to in this Section shall be payable to NationsBank in federal or
      other immediately available funds at NationsBank's address set forth
      herein.

3.    Notwithstanding anything contained to the contrary herein:

                (a) Applicant shall reimburse NationsBank for each draw
      (whether partial or full) under the Letter of Credit immediately after
      the payment of such draw by NationsBank; and

                (b) such reimbursement obligations shall bear interest at a
      rate per annum which shall from day to day be equal to (i) from (and
      including) the date of the payment of such draw by NationsBank until the
      third (3rd) day following the date on which NationsBank shall notify
      Applicant of such drawing, the lesser of the (A) maximum rate allowed by
      applicable law and (B) the variable rate of interest established from
      time to time by NationsBank as its general reference rate of interest
      (which rate of interest may not be the lowest rate charged by NationsBank
      on similar loans) plus one percent (1%), and (ii) from (and including)
      such third (3rd) day until (but excluding) the date such reimbursement
      obligations are paid, the maximum lawful rate.

4.    Payment of Reimbursement Obligations.  Applicant agrees to pay to
      NationsBank all reimbursement obligations, interest and other amounts
      payable to NationsBank under or in connection with the Letter of Credit
      immediately when due, irrespective of any claim, setoff, defense or
      other right which Applicant may have at any time against NationsBank or
      any other person. Each such payment shall be made to NationsBank in
      Federal or other immediately available funds at the NationsBank's address
      set forth below.

5.      INDEMNIFICATION; EXONERATION.        

                (a)      INDEMNIFICATION.  In addition to amounts payable as
        elsewhere provided herein, APPLICANT HEREBY AGREES TO PROTECT,
        INDEMNIFY, PAY AND SAVE NATIONSBANK AND ITS DIRECTORS, OFFICERS, AGENTS,
        ATTORNEYS AND EMPLOYEES HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS,
        DEMANDS, LIABILITIES, DAMAGES, LOSSES, COSTS, CHARGES AND EXPENSES
        (INCLUDING REASONABLE ATTORNEYS' FEES) WHICH NATIONSBANK MAY INCUR OR BE
        SUBJECT TO as a consequence, direct or indirect, of (i) Applicant's
        failure to make payments to NationsBank as required hereunder, (ii) the
        issuance of any Letter of Credit other than as a result of the gross
        negligence or willful misconduct of NationsBank, as determined by an
        arbitrator or arbitrators, or a court of competent jurisdiction, as
        appropriate, (BUT INCLUDING AS A RESULT OF THE ORDINARY NEGLIGENCE OF
        NATIONSBANK); or (iii) the failure of NationsBank to honor a drawing
        under a Letter of Credit as a result of any act or omission, whether
        rightful or wrongful, of any present or future de jure or de facto
        governmental authority.

                (b)      Assumption of Risk by Applicant.  As between Applicant
        and NationsBank, Applicant assumes all risks of the acts and omissions
        of, or misuse of the Letter of Credit by, the beneficiary of the Letter
        of Credit.  In furtherance and not in limitation of the foregoing,
        NationsBank shall not be responsible:

                        (i)     for the form, validity, sufficiency, accuracy,
        genuineness or legal effect of any document submitted by any party in
        connection with the application for and issuance of the Letter of
        Credit, even if it should in fact prove to be in any or all respects
        invalid, insufficient, inaccurate, fraudulent or forged; and

                        (ii)    for the validity or sufficiency of any 
        instrument transferring or assigning or purporting to transfer or
        assign the 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; and

                       (iii)   so long as the documentation delivered to 
        NationsBank conforms on its face to the requirements of the applicable
        Letter of Credit, for failure to the beneficiary of the Letter of Credit
        to comply duly with conditions required in order to draw upon such
        Letter of Credit; and

                        (iv)    for errors, omissions, interruptions or delays
        in transmission or delivery of any messages, by mail, cable, telegraph,
        telex or otherwise, whether or not they be in cipher, except for errors
        caused by the gross negligence or willful misconduct of NationsBank; and

                        (v)     for errors in interpretation of technical 
        terms, except for errors caused by the gross negligence or willful
        misconduct of NationsBank; and

                        (vi)    for any loss or delay in the transmission or 
        otherwise of any document required in order to make a drawing under the
        Letter of Credit or of the proceeds thereof, except for loss or delay
        caused by the gross negligence or willful misconduct of NationsBank; and

                        (vii)   for the misapplication by the beneficiary of 
        the Letter of Credit of the proceeds of any drawing under such Letter of
        Credit; and
<PAGE>   8
                (viii)  for any consequences arising from causes beyond the 
        control of NationsBank.

            None of the above shall affect, impair, or prevent the vesting of 
        any of NationsBank's rights or powers under this Section.

            (c)     Exoneration. In furtherance and extension, and not in
        limitation, of the specific provisions hereinabove set forth, any
        action taken omitted by NationsBank under or in connection with the
        Letter of Credit, if taken or omitted in good faith, shall not put
        NationsBank under any resulting liability to Applicant or relieve
        Applicant of any of its obligations hereunder to any Person.

6.      Financial Reports. Applicant shall promptly deliver to NationsBank such
        information concerning the business, properties or financial condition  
        of Applicant as NationsBank shall reasonably request including 
        financial statements or other reports or notices provided to

of time or both, would constitute a default) under, or permit cancellation of,
or result in the creation of any encumbrance upon, any of the Shares or any of
the assets of the Company under any of the terms, conditions, or provisions of
any contract, lease, sales order, purchase order, indenture, mortgage, note,
bond, instrument, license or other agreement to which the Company is a party,
or by which the Company or its assets is bound; (iv) permit the acceleration of
the maturity of any indebtedness of the Company; (v) violate or conflict with

convertible instruments, or other rights, agreements, or commitments to issue
or acquire any shares of common stock or any other security constituting, or
convertible or exchangeable into, capital stock of the Company.  Since the date
of the Company Balance Sheet (as defined in Section 4.6 below), no shares of
the Company's capital stock, no options, warrants, or other rights, agreements,
or commitments (contingent or otherwise) obligating the Company to issue shares
of capital stock, and no other securities or instruments convertible or
exchangeable into shares of capital stock, have been executed or issued by the
Company.  The Company has not granted and is not a party to any agreement
granting preemptive rights, rights of first refusal, or registration rights

<PAGE>   11
agency or indemnity agreement applicable to the issuance of shares of its
capital stock after the Effective Date.

       4.5       Licenses/Compliance with Law.  The Company has the lawful
authority and all federal, state or local governmental authorizations,
certificates of authority, licenses or permits necessary for or required to
conduct its respective business operations as such are presently being
conducted.  Schedule 4.5 contains a list and description of all authorizations,
certificates of authority, licenses and permits, including those granted or
derived from governmental sources, issued or granted to the Company.  The
Company is licensed to own and operate prepaid dental plans in the state of
Michigan and the states listed in Schedule 4.5.   For the proper conduct of its
business, the Company is not required to obtain any additional certificates of
authority, permits, licenses or similar authorizations from any governmental
authority other than has already obtained as listed on Schedule 4.5.  There are
no pending or, to the knowledge of the Sellers, threatened legal,
administrative, arbitration or other actions, notices, or proceedings nor any
pending or, to the knowledge of the Sellers, threatened governmental
investigations by any federal, state or local government or any subdivision
thereof or by any public or private group which assert or allege any violation
of or non- compliance with any governmental requirements or which would have
the effect of limiting, prohibiting or changing the business operations of the
Company as authorized by the authorizations, certificates of authority,
licenses and permits set forth on Schedule 4.5 and as presently conducted by
the Company.  The Company maintains statutory reserves that satisfy the
requirements of all applicable governmental laws, rules and regulations.  The
Company has made all filings with governmental agencies required for the
conduct of its respective business including, without limitation, all annual
reports and, all holding company statements required to be filed with insurance
or similar regulatory agencies and all filings required to sell the prepaid
dental benefit plans and coverage offered by the Company on the Effective Date.
There are no judgments against the Company, and no orders, rules, consent
decrees or injunctions of any court, governmental department, commission,
agency or instrumentality by which the Company is bound or to which the Company
is subject.  The Company has not entered into or is subject to any judgment,
consent decree, compliance order or administrative order with respect to any
insurance or other similar law or received any request for information, notice,
demand letter, administrative inquiry or formal or informal complaint or claim
with respect to any insurance or other similar law or the enforcement of any
such law.  Neither the Company's operations nor any of the assets owned,
leased, occupied or used by the Company in the operation of its business
materially violates or fails to comply in any material respect with any
applicable federal, state or local insurance, health maintenance organization,
or prepaid dental plan codes, laws, rules or regulations or, to the knowledge
of Sellers, federal, state or local health, fire, environmental, safety,
zoning, building or other codes, laws, rules or regulations, and the Company
has not received any notice of alleged violations thereof.

       4.6       Financial Statements.  The Company has delivered to Purchaser
a copy of (i) the audited financial statements of IDP as of December 31, 1995
consisting of a balance sheet at such date, and the related statements of
income, changes in stockholders' equity and cash flow for the applicable twelve
(12) month period then ended and (ii) unaudited financial statements of IDP as
of May 31, 1996 (the "Balance Sheet Date") consisting of a balance sheet of IDP
at





                                       5
<PAGE>   12
such date (the "Company Balance Sheet") and the related statements of income,
changes in stockholders' equity and cash flow for the applicable month and
year-to-date period then ended.  Complete and accurate copies of such financial
statements are attached hereto as Schedule 4.6 (the "Financial Statements").
The Financial Statements present fairly in all material respects the financial
position of the Company, and the results of the operations, changes in
stockholders' equity and cash flows of the Company, as of the respective dates
thereof and for the respective periods covered thereby, in conformity with
generally accepted accounting principles ("GAAP").  Except as set forth in the
Company Balance Sheet included in the Financial Statements, as of the Balance
Sheet Date there were no liabilities, debts, claims or obligations, whether
accrued, absolute, contingent or otherwise, whether due or to become due, which
are required by GAAP to be set forth in a balance sheet of the Company which
have not been so set forth in the Company Balance Sheet.  The Financial
Statements were prepared from the books and records of the Company.  There are
no assets shown on the Company Balance Sheet which are valued thereon at an
amount materially in excess of their fair value as of the Balance Sheet Date.
At the Balance Sheet Date, the Company owned each of the assets included in the
Company Balance Sheet.  From the date hereof through the Closing Date, the
Company will continue to prepare monthly and year-to-date unaudited financial
statements on the same basis and will promptly deliver the same to Purchaser.
The foregoing representations will be applicable to all such monthly unaudited
financial statements so prepared and delivered; provided, however, that such
unaudited financial statements shall be subject to normal year-end adjustments,
none of which will be material.

       4.7       No Adverse Change.  Except as set forth on Schedule 4.7, since
the Balance Sheet Date, the business of the Company has been conducted only in
the ordinary course and there has not been (i) any material adverse change in
the financial condition, business, properties, assets, or results of operations
of the Company (financial or otherwise) exclusive of any general economic
factors affecting the prepaid dental plan industry in general; (ii) any
material loss or damage (whether or not covered by insurance) to any of the
assets of the Company which materially affects or impairs the ability of the
Company to conduct its business as previously conducted or any other event or
condition of any character which has materially and adversely affected the
business or operations of the Company; (iii) the attaching, placing or granting
of, or the agreement to attach, place or grant, any encumbrance on any of the
assets of the Company; (iv) any sale or transfer of any material portion of the
assets of the Company; (v) any material changes in the terms of any contract of
the Company; (vi) any material change in the accounting systems, policies or
practices of the Company; (vii) any waiver by or on behalf of the Company of
any rights which have any material value; (viii) no taking under condemnation
or right of eminent domain of any of the assets of the Company; (ix) any entry
into or termination of any material commitment, contract, agreement, or
transaction (including, without limitation, any material borrowing or capital
expenditure or sale or other disposition of any material assets) by the
Company; (x) any redemption, repurchase, or other acquisition of any of its
capital stock by the Company, or any issuance of capital stock of the Company
or of securities convertible into or rights to acquire any such capital stock;
(xi) any dividend or distribution declared, set aside or paid on capital stock
of the Company; (xii) any transfer or right granted by the Company of or under
any material lease, license, agreement, patent, trademark, trade name, service
mark or copyright; (xiii) any sale or other disposition of any





                                       6
<PAGE>   13
material asset of the Company, or any mortgage, pledge, or imposition of any
lien or other encumbrance on any material asset of the Company, or any
agreement relating to or contemplating any of the foregoing not in the ordinary
and usual course of business; (xiv) any default or breach by the Company in any
material respect under any contract, license, or permit; or (xv) any material
increase in the statutory reserves required to be maintained by the Company.
Since the Balance Sheet Date, the Company has conducted its business only in
the ordinary and usual course of business and, without limiting the foregoing,
no changes have been made in (i) employee compensation levels, (ii) the manner
in which employees of the Company are compensated, (iii) supplemental benefits
provided to any employees, or (iv) the employment of any employees of the
Company.

       4.8       No Undisclosed Liabilities.  True and correct copies of all
notes, agreements or other documents evidencing the outstanding debt of the
Company, as amended to and in effect on the Effective Date, have been delivered
to Purchaser by the Company.  The Company has no liabilities which are not
adequately reflected or reserved against on the face of the Company Balance
Sheet, except liabilities incurred since the Balance Sheet Date in the ordinary
course of business consistent with past practice which, in the aggregate, would
not have a material adverse effect on the condition (financial or otherwise),
assets or business of the Company.  Schedule 4.8 hereto sets forth each
liability of the Company in an amount in excess of $10,000 and each person to
whom the aggregate amount of liabilities owed to such person by the Company
exceeds $10,000.

       4.9       Title to and Condition of Properties.  Except as disclosed in
Schedule 4.09 hereto, the Company has good, marketable, and insurable title, or
valid, effective and continuing leasehold rights in the case of leased
property, to all of the assets reflected on the Company Balance Sheet and all
personal property owned or leased by it or used by it in the conduct of its
business in such a manner as to create the appearance or reasonable expectation
that the same is owned or leased by it, free and clear of all liens, security
interests, restrictions, claims, encumbrances, and charges except as disclosed
in Schedule 4.9.  The Sellers do not know of any potential action or assertion
of rights, including condemnation, by any party, governmental or other, and no
proceedings with respect thereto have been instituted of which any Seller or
the Company has notice, that would materially affect the ability of the Company
to utilize each of such assets in its business.  The Company has not received
any notices of default or other violations from any mortgagee regarding any
properties leased by the Company.  Schedule 4.9 hereto contains a detailed
listing of all material assets of the Company.  The assets now owned by the
Company constitute all assets reasonably necessary to enable Purchaser to
conduct the business and operations of the Company on substantially the same
terms as such business has been conducted historically.  Except as disclosed in
Schedule 4.9, all such assets are well maintained and in good operating
condition, except for normal wear and tear.

       4.10      Litigation.  Except as set forth on Schedule 4.10 hereto, (i)
no material investigation or review by any governmental entity with respect to
the Company is pending or, to the knowledge of the Sellers, threatened, nor has
any governmental entity indicated to the Company an intention to conduct the
same; and (ii) there is no action, suit, or administrative, condemnation,
arbitration or other proceeding (including proceedings concerning labor
disputes





                                       7
<PAGE>   14
or grievances or union recognition) pending or, to the knowledge of the
Sellers, threatened against or affecting the Company to which the Company is a
party, at law or in equity, before any federal, state, or municipal court or
other governmental department, commission, board, bureau, agency, or
instrumentality.  The Company is not now, and has not been, a party to any

addition to the Schedules delivered by them under this Agreement promptly after
the occurrence of the same and again at the Closing by delivery of appropriate
updates to all such Schedules.  No notification of a change or addition to a

unless Purchaser specifically agrees thereto in writing, nor shall any such
notification be considered to constitute or give rise to a waiver by Purchaser

any matter or thing for the purposes of verifying the representations and
warranties made by Sellers herein.  Purchaser shall not be deemed to have
waived any misrepresentation or breach of warranty unless and except Purchaser
has actual knowledge of such misrepresentation or breach of warranty and
executes such waiver in writing.

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       11.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
if, prior to the expiration of such two year period, a state of facts shall
have become known which threatens to give rise to a liability against which any
party hereto would be entitled to indemnification hereunder and the indemnified
party shall have given notice of such facts to the indemnifying party, then the
rights of the indemnified party to indemnification with respect to such
liability shall continue until such liability shall have been finally
determined and disposed of (including and subject to disposition by the
expiration of the applicable statute of limitations with respect to such
liability); provided further, however, that if a claim for indemnification is
made pursuant to this Article 11, then such claim for indemnification or any
claim arising out of the wrongful failure to comply with the provisions of this
Article 11 shall survive until the expiration of the applicable period of
limitations with respect to such claim for indemnification; and provided
further, however, that such two year limitation specified above shall not apply
to the extent provided otherwise in Section 11.4(c) below.  With respect to the
representations and warranties of the parties, such representations and
warranties shall be true as of and at the date of the Closing but nothing
contained herein shall be deemed to require or imply that the accuracy of such
representations and warranties shall apply on a continuing basis as to facts
existing after the date of the Closing.  Except to the





                                       27
<PAGE>   34
extent set forth herein, no investigation or examination made by any party
hereto shall constitute a waiver of any representation or warranty and no
representation or warranty shall be merged into the Closing hereunder.
However, to the extent information is apparent on the face of the Schedules or
is otherwise expressly set forth herein, such information shall be deemed to
amend, limit and/or restate any representation and warranties contained herein
to the extent such information is inconsistent with such representation or
warranty.

       11.2      Indemnity.  Subject to the provisions of Section 11.4 below,

                 (a)      Sellers.  Each Seller, jointly and severally (except
as to the representations and warranties contained in Article 3 which shall be
several and not joint), agrees to indemnify and hold harmless the Company, each
Subsidiary, and Purchaser, and their respective shareholders, partners,
directors, officers, employees and agents, from, against, and in respect of,
any loss, liability, claim, demand, or expense, including but not limited to
attorney, investigation and consultant fees and costs, and of any other kind
whatsoever arising out of or resulting from any of the following:

                   (i)    Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers and the Company
       under this Agreement or under any other agreement or document delivered
       by the Sellers at Closing hereunder; and

                  (ii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold each
Seller harmless from, against, and in respect of, any loss, liability, claim,
demand, or expense, including but not limited to attorney's fees and costs, of
any kind whatsoever, arising out of or resulting from any of the following:

                   (i)    Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Sellers at Closing hereunder;

                  (ii)    Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Sellers are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 11.2(a) above; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       11.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
11.2(a) or 11.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in





                                       28
<PAGE>   35
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might result in any such claim, demand or
action, such party shall promptly notify the other party or parties who would
be obligated to provide indemnity hereunder with respect to such claim, demand
or action, and such other party or parties shall have the right to take such
action as it or they may deem appropriate to resolve such matter.  The
indemnified party or parties shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties, unless the employment of such counsel has been specifically authorized
by the indemnifying party or parties.  Any settlement of any action subject to
indemnity hereunder shall require the consent of the indemnified and the
indemnifying party which consent shall not be unreasonably withheld and shall
be given within five (5) days following the giving of notice thereof; provided,
however, that with respect to the Roberts claim described in Schedule 4.10, the
Sellers shall have the sole authority to approve any settlement of such claim.
The indemnifying party or parties shall not be liable for any settlement of any
action effected without its or their consent, but if settled with the consent
of the indemnifying party or parties or if there be a final judgment for the
plaintiff in any such action, the indemnifying party or parties shall indemnify
and hold harmless the indemnified party from and against any loss or liability
by reason of such settlement or judgment.  If requested by the indemnifying
party, the indemnified party shall cooperate with the indemnifying party and
its counsel and use its best efforts in contesting any such claim or, if
appropriate, in making any counter-claim or cross-complaint against the party
asserting the claim, provided that the indemnifying party will reimburse the
indemnified party for reasonable expenses incurred in so cooperating upon
presentation of receipts or other evidence of such expense.  The indemnifying
party and its representatives shall have full and complete access during
reasonable hours to all books, records and files of the indemnified party
expressly related to the defense of any claim for indemnification undertaken by
the indemnifying party pursuant to this Article 11, or for any other purpose in
connection therewith; provided that the indemnifying party shall safeguard and
maintain the confidentiality of all such books, records and files.

       11.4      Limitations on Indemnification.

                 (a)      General Threshold.  Except as to indemnification
obligations of the Sellers under Section 11.2(a)(ii) above as to which the
following limitation shall not apply, neither the Sellers nor the Purchaser
shall be obligated to indemnify the other party except to the extent that the
cumulative amount of all indemnifiable losses exceeds Five Thousand Dollars
($5,000.00) (the "Threshold"), which excess amount shall be recoverable in
accordance with the terms hereof; provided, however, that such limitation set
forth in this Section 11.4(a) shall not apply to the matters described in
Section 11.4(c).  With respect to any indemnifiable loss payable by the
Sellers, the funds in the Post-Closing Escrow Account shall be used for such
purpose first before any recovery is sought directly from a Seller; provided,
however, that to the extent the indemnification loss or losses exceed the funds
in the Post-Closing Escrow Account, then the Purchaser may seek recovery of
the amount of such indemnifiable loss in excess of such funds contemporaneously
with the recovery of any funds in the Post-Closing Escrow Account.





                                       29
<PAGE>   36
                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 11.1 and this Section 11.4(b) shall not apply
to the matters described in Section 11.4(c) as to which the indemnification
obligations hereunder shall expire six (6) months after the termination of the
applicable statute of limitations relating to the subject matter covered by
such provisions; and provided further, however, that in each case if, prior to
the applicable date of expiration, a specific state of facts shall have become
known which is reasonably likely to constitute or give rise to any
indemnifiable loss as to which indemnity may be payable and the indemnified
party shall have given notice of such facts to the indemnifying party and made
a claim for indemnification within such two-year period, then the right to
indemnification with respect thereto shall remain in effect until such matter
shall have been finally determined and disposed of and any indemnification due
in respect thereof shall have been paid.

                 (c)      Certain Matters.  The following are the matters
referred to in Section 11.4(a) and Section 11.4(b):

                 (i)      Losses arising from fraud or an intentional
       misrepresentation on the part of any Seller; and

                 (ii)     Losses arising from the intentional breach of any
       covenant or agreement by a Seller contained in this Agreement.

       11.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Sellers and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       11.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing.  In the event
that the Purchaser shall elect to pay or cause the Company to pay any severance
benefits to employees of the Company who may be terminated at or after the
Closing, it is expressly understood that the Sellers shall not be entitled to
receive such severance benefits.

       11.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 4.21 with the





                                       30

case of Purchaser, as provided in Article 9, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this
Agreement unless the failure of the condition is the result of the material
breach of this Agreement by the party seeking to terminate; provided, however,
that, in the event all such conditions have been satisfied except solely the
condition with respect to obtaining all required consents, authorizations, and
approvals of governmental and regulatory agencies set forth in Sections 8.1(a)
and 9.1(a), respectively, and such failure is not due to a breach of this
Agreement by the non-terminating party, such date shall be automatically
extended for three (3) successive thirty (30) day periods so long as such
remains to be the case at the end of each respective thirty (30) day and
provided, further, that in no event shall such date be extended beyond an
aggregate of two hundred ten (210) days after the date of this Agreement unless
extended by the mutual agreement of the Purchaser and the Sellers;

                 (c)      By Purchaser or Sellers: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Sellers, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) two hundred ten (210)
days after the date of this Agreement, unless such date is extended by mutual
agreement of Purchaser and Sellers.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination.  Any
public announcement of the termination of this Agreement shall be made only by
means of a press release issued jointly by Purchaser and the Company.

       12.2      Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Sellers, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

Any party may change the address or facsimile telephone number for notices to

14.2.

       14.3      Entire Agreement; Amendments.  This Agreement and the
documents to be delivered at Closing hereunder set forth the entire
understanding of the parties and supersede all prior agreements or
understandings, whether written or oral, with respect to the subject matter
hereof.  This Agreement may be amended, modified or supplemented only by a
written agreement executed by Purchaser and Sellers.

       14.4      Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any affiliate of
Purchaser without the necessity of seeking the consent of the Sellers;
provided, however, that Purchaser shall not be relieved of any obligations as a
result of such assignment





                                       35

and that, in addition to Purchaser remaining liable, any such assignee shall
assume and become liable for any and all of Purchaser's obligations under this
Agreement.  None of the Sellers shall be entitled to assign any of their
respective rights or obligations under this Agreement; provided, however, that
the rights and obligations of a Seller may be assigned by operation of law or
may be assigned to an individual retirement account, pension plan, trust or
other entity under the control of such Seller but any such assignment shall not
relieve or release such Seller of any obligations hereunder as a result of such
assignment and that, in addition to such Seller remaining liable, any such
assignee shall assume and become liable for any and all of such Seller's
obligations under this Agreement. In connection with any such assignment, a
Seller may transfer all or any portion of the Shares owned by the Seller and
thereby effect an assignment on the basis specified above.

       14.5      Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

       14.7      Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

       14.8      Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

       14.9      Consent to Jurisdiction.  Each party hereto hereby irrevocably
consents to the jurisdiction of a state or federal court setting in either
Oakland County, Michigan or Dallas County, Texas in any action or proceeding
arising out of or relating to this Agreement or any agreement executed and
delivered pursuant to this Agreement and agrees that all claims in respect of
such action or proceeding may be heard and determined in either of such state
or federal courts.

       14.10     Time.  Time is of the essence under this Agreement.

                              CONSULTING AGREEMENT


         This Consulting Agreement ("Agreement") is made as of the ____ day of
______________, 1996, by and between Patricia L. Schubring ("Schubring") and
United Dental Care, Inc., a Delaware corporation (the "Company").

         WHEREAS, the Company, Independent Dental Plans, Inc., a Michigan
corporation ("IDP") and other subsidiaries of the Company are engaged in
providing several products and services relating to the dental health industry,
including, without limitation, prepaid dental plans and the provision of
management, administrative and related services to such entities and prepaid
dental plans; and

         WHEREAS, Schubring has been actively engaged in the development and
management of the business operations conducted by IDP and its subsidiaries;
and

         WHEREAS, Schubring is a principal stockholder of IDP stock; and

         WHEREAS, simultaneously with the execution of this Agreement, the
Company is acquiring all the issued and outstanding Common Stock of IDP
pursuant to a Stock Purchase Agreement dated June 28, 1996 by and among
Schubring and the other stockholders of IDP, the Company and IDP (the "Stock
Purchase Agreement"); and

         WHEREAS, the Company desires in connection with such acquisition to
enter into this Agreement with Schubring and Schubring is willing to enter into
this Agreement with the Company, in each case on and subject to the terms and
conditions hereinafter set forth;

         NOW, THEREFORE, in consideration of the premises and the mutual terms
and conditions herein contained, Schubring and the Company hereby agree as
follows:

         1. Services. Subject to the terms and conditions hereinafter set
forth, and for a period from the date of this Agreement until December 31,
1999, the Company hereby retains Schubring for, and Schubring hereby agrees to
provide to the Company, her services as an independent consultant and advisor
(and not as an employee) with respect to such business and financial matters of
the Company and its subsidiaries, as may be reasonably requested by the Company
from time to time; provided, however, that Schubring shall not be required to
render such services in person or at any particular location, shall not be
required to render such services at any time that such would interfere with her
other business obligations, and may render such services by telephonic means.

         2. Covenant Not to Compete; Non-Solicitation. Schubring acknowledges
and agrees that:



                                       1
<PAGE>   46



                  (a) the Company and its subsidiaries including, without
         limitation, IDP and its subsidiaries (collectively referred to
         hereinafter as the "Company") engage in (i) the operation of a dental
         health indemnity insurance company, (ii) the operation of prepaid
         dental plans, and (iii) the provision of management, administrative
         and related services to dental health providers, dental health
         indemnity insurance carriers and prepaid dental plans (collectively
         the "Dental Services Business"); and

                  (b) the Company engages in the Dental Services Business in
         numerous states and plans to expand the Dental Services Business
         operated by the Company to all the states in the continental United
         States; and

                  (c) the Dental Services Business of the Company would be
         materially adversely impacted if Schubring competed with the Company
         because of her knowledge, expertise and experience in the Dental
         Services Business conducted by the Company and its subsidiaries.

         For and in consideration of the foregoing facts and the payments
payable by the Company pursuant to this Agreement, Schubring covenants and
agrees that she shall not, directly or indirectly, as an employee, employer,
consultant, creditor, investor, owner, agent, principal, partner, shareholder,
corporate officer, director or through any other kind of ownership (other than
ownership of securities of any publicly held entity in which Schubring,
directly or indirectly, in the aggregate owns less than eight percent (8%) of
any class of outstanding securities), or in any other representative or
individual capacity, do any of the following:

                  1. for the period from the date of this Agreement to December
         31, 1999, engage in any Dental Services Business in the States of
         Michigan, Ohio, Indiana and Pennsylvania (the "Restricted Area") that
         is in competition in any manner whatsoever with the Dental Services
         Business conducted by the Company, including, without limitation, the
         business of a dental health indemnity insurance company, a prepaid
         dental plan, or the provision of management, administrative, or
         related services to any of the foregoing anywhere in the Restricted
         Area; provided, however, that Schubring may engage in the ownership,
         operation and management of a dental "preferred provider organization"
         (as such term is generally understood in the health care industry
         which does not include ownership and operation of a prepaid dental
         plan);

                  2. for the period from the date of this Agreement to December
         31, 1999, engage in any business which calls upon, solicits, diverts
         or takes away any customer or customers of the Company in the
         Restricted Area for the purpose of selling or attempting to sell to
         any of said customers any products or services similar to any products
         or services sold or provided to any of such customers by the Company;
         provided, however, that Schubring may call on such customers in
         connection with the operation of a dental preferred provider
         organization; and

                  3. for the period from the date of this Agreement to December
         31, 1999, engage in any business which solicits any present or future
         employee of the Company or



                                       2
<PAGE>   47



         initiates discussions with any such employee regarding his or her
         termination or resignation from employment with the Company, so that
         such employee may accept employment with, or engagement as a partner,
         investor, shareholder, employee, agent or consultant with Schubring,
         directly or indirectly, as specified above.

         It is expressly agreed and understood that nothing contained herein
shall be deemed or construed to prohibit Schubring on an individual basis from
engaging in public speeches or publishing written articles or providing
services for public agencies concerning the Dental Services Business so long as

proprietary business information which is the property of the Company and that,
unless otherwise required by law, from and after the date of this Agreement:

                  (a) Schubring shall use her best efforts and exercise utmost
         diligence to protect and safeguard all of such trade secrets and
         confidential, proprietary information;

                  (b) Schubring shall not, directly or indirectly, use, sell,

         5. Consideration.

                  (a) As consideration for the agreements of Schubring
         contained herein, the Company shall pay to Schubring the following
         payments (the "Performance Payments"), to-wit:

                           (1) With respect to each of the calendar years
         ending December 31, 1997, 1998 and 1999, a Performance Payment shall
         be paid in an amount equal to two and one-half (2.5) times the amount
         by which Adjusted Operating Profit (defined below) for such respective
         calendar year exceeds the Adjusted Operating Profit for the
         Performance Payment Base Year; provided, however, that the Performance
         Payment with respect to any one calendar year shall be limited to a
         maximum amount of One Hundred Thousand Dollars ($100,000.00).

                           (2) As used herein, the term "Adjusted Operating
         Profit" shall mean an amount equal to the total premium revenues less
         total dental services expenses and total sales and marketing expenses
         attributable to the Dental Services Business of the Company conducted
         in the State of Michigan and less also all employment compensation
         paid to Schubring and Edward K. Halstead by IDP or the Company for
         such calendar year; provided, however, that Adjusted Operating Profit
         shall not be reduced by any Performance Payments paid to Schubring
         hereunder or to Edward K. Halstead under that certain Consulting
         Agreement between the Company and Halstead of even date herewith and
         provided further that the term "dental services expenses" and "sales
         and marketing expenses" shall have the same meaning as such terms have
         been and are used in the preparation of the financial statements of
         the Company and shall be determined in a manner consistent with the
         past practices of the Company.

                           (3) As used herein, the term "Performance Payment
         Base Year" shall mean the calendar year preceding the calendar year
         with respect to which the Performance Payment is being determined,
         i.e, 1996 for the 1997 Performance Payment; 1997 for the 1998
         Performance Payment and 1998 for the 1999 Performance Payment.

                           (4) In the event that the Company, directly or
         indirectly, acquires any other entity engaged in the Dental Services
         Business in the State of Michigan (or the assets thereof), it is
         agreed and understood that the Adjusted Operating Profit of such
         entity determined for a twelve month period ending as of the end of
         the month preceding the month in which such acquisition occurs shall
         be added to the Adjusted Operating Profit of the Company for the
         Performance Payment Base Year (such amount to be prorated, however,
         for the purposes of determining the Performance Payment to take into
         account only a percentage thereof equal to the percentage of the
         calendar year prior to the date on which such acquisition occurs) and
         that the results of operations of each such entity from and after the
         effective date of the acquisition for accounting purposes shall be
         included in determining the Adjusted Operating Profit for the year in
         which the acquisition occurs, and each year thereafter with respect to
         which a Performance Payment is payable. Notwithstanding the foregoing,
         in the event the Company acquires




                                       4
<PAGE>   49



         any entity or the assets thereof, which had a Negative Adjusted
         Operating Profit for the twelve month period prior to the date of the
         acquisition, then no adjustment shall be made for the purposes of
         determining the Adjusted Operating Profit for the Performance Payment
         Base Year and the results of operations of such entity shall not be
         included in determining Adjusted Operating Profit until and including
         the first calendar month that such entity (or assets) have positive
         Adjusted Operating Income.

                           (5) Each Performance Payment under this Agreement
         shall be due and payable on or before March 31 of the following year.
         The Company shall submit with each Performance Payment, or in lieu
         thereof if no Performance Payment is due, a schedule reflecting the
         calculation of the Performance Payment due with respect to the
         calendar year then ended. Schubring, at her expense, shall have access
         to and the right to examine and audit the books, records and financial
         statements of the Company for the purposes of verifying the
         calculation of such Performance Payment.

                  (b) As additional consideration for the agreements of
         Schubring contained herein, the Company shall also pay to Schubring
         the additional amount of $50,000 in the event that IDP successfully
         renews its group agreement with Great Lakes Steel Company for the 1997
         calendar year on contract terms no less favorable than the group
         agreement with Great Lakes Steel Company in effect for the 1996
         calendar year. In the event such renewal occurs prior to the date of
         this Agreement, such amount shall be payable on the date of this
         Agreement. Otherwise such amount shall be payable within three (3)
         business days after the date that such renewal occurs.

                  (c) It is expressly agreed and understood that the payments
         set forth under paragraphs (a) and (b) above constitutes the entire
         and complete consideration payable to Schubring for her agreements
         contained herein.

         6. Employment. Nothing contained in this Agreement shall be deemed to
constitute an employment agreement or any type of partnership or joint venture
between the Company and Schubring. However, it is understood that the Company
may by separate agreement employ Schubring and, in such event, the performance
by Schubring of her employment responsibilities shall not constitute a
violation or breach of the provisions of this Agreement.

         7. Reasonableness; Reformation. Schubring acknowledges and agrees that
(i) this Agreement is ancillary to the Stock Purchase Agreement pursuant to
which the Company acquired all the issued and outstanding capital stock of IDP,
(ii) the provisions of this Agreement contain reasonable limitations as to
time, geographical area and scope of activities to be restrained and do not
impose a greater restraint than is necessary to protect goodwill and other
business interests of the Company and its subsidiaries, (iii) if any portion of
the covenants and agreements set forth in this Agreement are held to be
invalid, unreasonable, arbitrary or against public policy, then such portion of
such covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against



                                       5
<PAGE>   50



public policy, a lesser time period, scope of activities covered, and/or
geographical area which is determined to be reasonable, non-arbitrary and not
against public policy may be enforced against Schubring.

         8. Remedies for Breach. Any one or more of the following remedies, as
selected by the Company in its sole discretion, shall be available to the
Company in the event of a breach of this Agreement by Schubring hereunder:

                  (a) Specific Performance. In the event of a breach or
         threatened breach of any covenant or agreement of Schubring in this
         Agreement, remedies at law will not adequately compensate the Company
         for its injuries incurred as a result thereof. Accordingly, injunctive
         and/or equitable relief shall be available to the Company to
         specifically enforce this Agreement and prevent such breach and any
         continued breach of any covenant and agreement herein. Schubring
         agrees that a bond of no more than $10,000 in the aggregate will
         provide adequate protection to Schubring and therefore no more than
         $10,000 in bond or other security shall be required to be posted by
         the Company by any court in any proceeding to obtain such injunctive
         or equitable relief.

                  (b) Suit for Damages. In addition to the remedies stated in
         Section 7(a) above, in the event of any breach of any covenant or
         agreement of Schubring herein, the Company may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Company under applicable law.

         9. Waivers Applicable to Covenants Not to Compete. In its sole
discretion, the Company shall have the right at any time and from time to time,
evidenced solely by the written approval of the Board of Directors of the
Company, to waive all or any portion of the rights of the Company under this
Agreement as applicable to Schubring, including, without limitation, reducing
the scope of covenant not to compete applicable to Schubring or reducing the
time period or the geographical area of the covenant not to compete applicable
to Schubring; provided that as so amended by waiver such covenant not to
compete shall remain fully in effect. In order to be effective, any such waiver
must be in writing, approved by the Board of Directors of the Company as
provided above, and executed by an authorized officer of the Company.

         10. Death or Disability of Schubring. In consideration of the business
opportunities that Schubring will forego as a result of the performance of this
Agreement by Schubring, it is expressly understood that the death or disability
of Schubring shall not relieve or release the Company from its obligations
under this Agreement. In the event of the death of Schubring, payment under
this Agreement shall continue to be made as specified in this Agreement and the
estate or designated beneficiary of Schubring shall be entitled to exercise all
rights and remedies of such member of Schubring under this Agreement.

         11. Miscellaneous.

                  (a) Notices. Any notices, claims or demands which any party
         is required or may desire to give to another under or in conjunction

         understanding of the parties and supersedes all prior agreements or
         understandings, whether written or oral, with respect to the subject
         matter hereof. No terms, conditions, or warranties, other than those

                  (c) Binding Effect/Assignability. This Agreement shall extend
         to and be binding upon and inure to the benefit of the parties hereto,
         their respective heirs, legal representatives, successors and assigns.
         Schubring shall not have any right at any time to assign this
         Agreement to any person or entity without the prior written consent of
         all other parties hereto; provided, however, that Schubring may assign
         the right to receive all payments hereunder to a corporation, limited
         liability company, or limited or general partnership of which he or it
         is the controlling shareholder, member or partner but no such

         breach of or exercise of any rights under this Agreement shall not be
         deemed to be a waiver of similar or other breaches or rights or a
         future breach of the same duty. The failure of a party to take any
         action by reason of any such breach or to exercise any such right
         shall not deprive any party of the right to take any action at any
         time while such breach or condition giving rise to such right
         continues. The parties shall have all remedies permitted to them by
         this Agreement or law, and all such remedies shall be cumulative.

                  (f) Consent of Jurisdiction. Each party hereto hereby

                  (h) Governing Law. This Agreement shall be construed under
         and governed by the internal laws, and not the law of conflicts, of
         the State of Michigan.

                  (i) Counterparts. This Agreement may be executed in two or
         more counterparts, each of which shall be deemed an original, but
         which together shall constitute one and the same agreement.

                              CONSULTING AGREEMENT


         This Non-Competition Agreement ("Agreement") is made as of the ____
day of ______________, 1996, by and between Edward K. Halstead ("Halstead") and
United Dental Care, Inc., a Delaware corporation (the "Company").

         WHEREAS, the Company, Independent Dental Plans, Inc., a Michigan
corporation ("IDP") and other subsidiaries of the Company are engaged in
providing several products and services relating to the dental health industry,
including, without limitation, prepaid dental plans and the provision of
management, administrative and related services to such entities and prepaid
dental plans; and

         WHEREAS, Halstead has been actively engaged in the development and
management of the business operations conducted by IDP and its subsidiaries;
and

         WHEREAS, Halstead is a principal stockholder of IDP stock; and

         WHEREAS, simultaneously with the execution of this Agreement, the
Company is acquiring all the issued and outstanding Common Stock of IDP
pursuant to a Stock Purchase Agreement dated June 28, 1996 by and among
Halstead and the other stockholders of IDP, the Company and IDP (the "Stock
Purchase Agreement"); and

         WHEREAS, the Company desires in connection with such acquisition to
enter into this Agreement with Halstead and Halstead is willing to enter into
this Agreement with the Company, in each case on and subject to the terms and
conditions hereinafter set forth;

         NOW, THEREFORE, in consideration of the premises and the mutual terms
and conditions herein contained, Halstead and the Company hereby agree as
follows:

         1. Services. Subject to the terms and conditions hereinafter set
forth, and for a period from the date of this Agreement until December 31,
1999, the Company hereby retains Halstead for, and Halstead hereby agrees to
provide to the Company, his services as an independent consultant and advisor
(and not as an employee) with respect to such business and financial matters of
the Company and its subsidiaries, as may be reasonably requested by the Company
from time to time; provided, however, that Halstead shall not be required to
render such services in person or at any particular location, shall not be
required to render such services at any time that such would interfere with his
other business obligations, and may render such services by telephonic means.


         2. Covenant Not to Compete; Non-Solicitation. Halstead acknowledges
and agrees that:


                                       1
<PAGE>   55



                  (a) the Company and its subsidiaries including, without
         limitation, IDP and its subsidiaries (collectively referred to
         hereinafter as the "Company") engage in (i) the operation of a dental
         health indemnity insurance company, (ii) the operation of prepaid
         dental plans, and (iii) the provision of management, administrative
         and related services to dental health providers, dental health
         indemnity insurance carriers and prepaid dental plans (collectively
         the "Dental Services Business"); and

                  (b) the Company engages in the Dental Services Business in
         numerous states and plans to expand the Dental Services Business
         operated by the Company to all the states in the continental United
         States; and

                  (c) the Dental Services Business of the Company would be
         materially adversely impacted if Halstead competed with the Company
         because of his knowledge, expertise and experience in the Dental
         Services Business conducted by the Company and its subsidiaries.

         For and in consideration of the foregoing facts and the payments
payable by the Company pursuant to this Agreement, Halstead covenants and
agrees that he shall not, directly or indirectly, as an employee, employer,
consultant, creditor, investor, owner, agent, principal, partner, shareholder,
corporate officer, director or through any other kind of ownership (other than
ownership of securities of any publicly held entity in which Halstead, directly
or indirectly, in the aggregate owns less than eight percent (8%) of any class
of outstanding securities), or in any other representative or individual
capacity, do any of the following:

                  1. for the period from the date of this Agreement to December
         31, 1999, engage in any Dental Services Business in the States of
         Michigan, Ohio, Indiana and Pennsylvania (the "Restricted Area") that
         is in competition in any manner whatsoever with the Dental Services

         Area; provided, however, that Halstead may engage in the ownership,
         operation and management of a dental "preferred provider organization"
         (as such term is generally understood in the health care industry
         which does not include ownership and operation of a prepaid dental

         organization; and

                  3. for the period from the date of this Agreement to December

proprietary business information which is the property of the Company and that,
unless otherwise required by law, from and after the date of this Agreement:

                  (a) Halstead shall use his best efforts and exercise utmost
         diligence to protect and safeguard all of such trade secrets and
         confidential, proprietary information;

                  (b) Halstead shall not, directly or indirectly, use, sell,

         5. Consideration.

                  (a) As consideration for the agreements of Halstead contained
         herein, the Company shall pay Halstead the following payments (the
         "Performance Payments"), to- wit:

                           (1) With respect to each of the calendar years
         ending December 31, 1997, 1998 and 1999, a Performance Payment shall
         be paid in an amount equal to two and one-half (2.5) times the amount
         by which Adjusted Operating Profit (defined below) for such respective
         calendar year exceeds the Adjusted Operating Profit for the
         Performance Payment Base Year; provided, however, that the Performance
         Payment with respect to any one calendar year shall be limited to a
         maximum amount of One Hundred Thousand Dollars ($100,000.00).

                           (2) As used herein, the term "Adjusted Operating
         Profit" shall mean an amount equal to the total premium revenues less
         total dental services expenses and total sales and marketing expenses
         attributable to the Dental Services Business of the Company conducted
         in the State of Michigan and less also all employment compensation
         paid to Halstead and Patricia L. Schubring by IDP or the Company for
         such calendar year; provided, however, that Adjusted Operating Profit
         shall not be reduced by any Performance Payments paid to Halstead
         hereunder or to Patricia L. Schubring under that certain Consulting
         Agreement between the Company and Schubring of even date herewith and
         provided further that the term "dental services expenses" and "sales
         and marketing expenses" shall have the same meaning as such terms have
         been and are used in the preparation of the financial statements of
         the Company and shall be determined in a manner consistent with the
         past practices of the Company.

                           (3) As used herein, the term "Performance Payment
         Base Year" shall mean the calendar year preceding the calendar year
         with respect to which the Performance Payment is being determined,
         i.e, 1996 for the 1997 Performance Payment; 1997 for the 1998
         Performance Payment and 1998 for the 1999 Performance Payment.

                           (4) In the event that the Company, directly or
         indirectly, acquires any other entity engaged in the Dental Services
         Business in the State of Michigan (or the assets thereof), it is
         agreed and understood that the Adjusted Operating Profit of such
         entity determined for a twelve month period ending as of the end of
         the month preceding the month in which such acquisition occurs shall
         be added to the Adjusted Operating Profit of the Company for the
         Performance Payment Base Year (such amount to be prorated, however,
         for the purposes of determining the Performance Payment to take into
         account only a percentage thereof equal to the percentage of the
         calendar year prior to the date on which such acquisition occurs) and
         that the results of operation of each such entity from and after the
         effective date of the acquisition for accounting purposes shall be
         included in determining the Adjusted Operating Profit for the year in
         which the acquisition occurs, and each year thereafter with respect to
         which a Performance Payment is payable. Notwithstanding the foregoing,
         in the event the Company acquires 



                                       4
<PAGE>   58


         any entity or the assets thereof, which had a Negative Adjusted
         Operating Profit for the twelve month period prior to the date of the
         acquisition, then no adjustment shall be made for the purposes of
         determining the Adjusted Operating Profit for the Performance Payment
         Base Year and the results of operations of such entity shall not be
         included in determining Adjusted Operating Profit until and including
         the first calendar month that such entity (or assets) have positive
         Adjusted Operating Income.

                           (5) Each Performance Payment under this Agreement
         shall be due and payable on or before March 31 of the following year.
         The Company shall submit with each Performance Payment, or in lieu
         thereof if no Performance Payment is due, a schedule reflecting the
         calculation of the Performance Payment due with respect to the
         calendar year then ended. Halstead, at his expense, shall have access
         to and the right to examine and audit the books, records and financial
         statements of the Company for the purposes of verifying the
         calculation of such Performance Payment.

                  (b) As additional consideration for the agreements of
         Halstead contained herein, the Company shall also pay to Halstead the
         additional amount of $50,000 in the event that IDP successfully renews
         its group agreement with Great Lakes Steel Company for the 1997
         calendar year on contract terms no less favorable than the group
         agreement with Great Lakes Steel Company in effect for the 1996
         calendar year. In the event such renewal occurs prior to the date of
         this Agreement, such amount shall be payable on the date of this
         Agreement. Otherwise such amount shall be payable within three (3)
         business days after the date that such renewal occurs.

                  (c) It is expressly agreed and understood that the payments
         set forth under paragraphs (a) and (b) above constitutes the entire
         and complete consideration payable to Halstead for his agreements
         contained herein.

         6. Employment. Nothing contained in this Agreement shall be deemed to
constitute an employment agreement or any type of partnership or joint venture
between the Company and Halstead. However, it is understood that the Company
may by separate agreement employ Halstead and, in such event, the performance
by Halstead of his employment responsibilities shall not constitute a violation
or breach of the provisions of this Agreement.

         7. Reasonableness; Reformation. Halstead acknowledges and agrees that
(i) this Agreement is ancillary to the Stock Purchase Agreement pursuant to
which the Company acquired all the issued and outstanding capital stock of IDP,
(ii) the provisions of this Agreement contain reasonable limitations as to
time, geographical area and scope of activities to be restrained and do not
impose a greater restraint than is necessary to protect goodwill and other
business interests of the Company and its subsidiaries, (iii) if any portion of
the covenants and agreements set forth in this Agreement are held to be
invalid, unreasonable, arbitrary or against public policy, then such portion of
such covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against 



                                       5
<PAGE>   59


public policy, a lesser time period, scope of activities covered, and/or
geographical area which is determined to be reasonable, non-arbitrary and not
against public policy may be enforced against Halstead.

         8. Remedies for Breach. Any one or more of the following remedies, as
selected by the Company in its sole discretion, shall be available to the
Company in the event of a breach of this Agreement by Halstead hereunder:

                  (a) Specific Performance. In the event of a breach or
         threatened breach of any covenant or agreement of Halstead in this
         Agreement, remedies at law will not adequately compensate the Company
         for its injuries incurred as a result thereof. Accordingly, injunctive
         and/or equitable relief shall be available to the Company to
         specifically enforce this Agreement and prevent such breach and any
         continued breach of any covenant and agreement herein. Halstead agrees
         that a bond of no more than $10,000 in the aggregate will provide
         adequate protection to Halstead and therefore no more than $10,000 in
         bond or other security shall be required to be posted by the Company
         by any court in any proceeding to obtain such injunctive or equitable
         relief.

                  (b) Suit for Damages. In addition to the remedies stated in
         Section 7(a) above, in the event of any breach of any covenant or
         agreement of Halstead herein, the Company may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Company under applicable law.

         9. Waivers Applicable to Covenants Not to Compete. In its sole
discretion, the Company shall have the right at any time and from time to time,
evidenced solely by the written approval of the Board of Directors of the
Company, to waive all or any portion of the rights of the Company under this
Agreement as applicable to Halstead, including, without limitation, reducing
the scope of covenant not to compete applicable to Halstead or reducing the
time period or the geographical area of the covenant not to compete applicable
to Halstead; provided that as so amended by waiver such covenant not to compete
shall remain fully in effect. In order to be effective, any such waiver must be
in writing, approved by the Board of Directors of the Company as provided
above, and executed by an authorized officer of the Company.

         10. Death or Disability of Halstead. In consideration of the business
opportunities that Halstead will forego as a result of the performance of this
Agreement by Halstead it is expressly understood that the death or disability
of Halstead shall not relieve or release the Company from its obligations under
this Agreement. In the event of the death of Halstead, payment under this
Agreement shall continue to be made as specified in this Agreement and the
estate or designated beneficiary of Halstead shall be entitled to exercise all
rights and remedies of such member of Halstead under this Agreement.

         11. Miscellaneous.

                  (a) Notices. Any notices, claims or demands which any party
         is required or may desire to give to another under or in conjunction

                  (c) Binding Effect/Assignability. This Agreement shall extend
         to and be binding upon and inure to the benefit of the parties hereto,
         their respective heirs, legal representatives, successors and assigns.
         Halstead shall not have any right at any time to assign this Agreement
         to any person or entity without the prior written consent of all other

         to receive all payments hereunder to a corporation, limited liability

         breach of or exercise of any rights under this Agreement shall not be
         deemed to be a waiver of similar or other breaches or rights or a
         future breach of the same duty. The failure of a party to take any
         action by reason of any such breach or to exercise any such right
         shall not deprive any party of the right to take any action at any
         time while such breach or condition giving rise to such right
         continues. The parties shall have all remedies permitted to them by
         this Agreement or law, and all such remedies shall be cumulative.

                  (h) Governing Law. This Agreement shall be construed under
         and governed by the internal laws, and not the law of conflicts, of
         the State of Michigan.

                  (i) Counterparts. This Agreement may be executed in two or
         more counterparts, each of which shall be deemed an original, but

trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and thereafter, the Executive
covenants and agrees as follows:

                  (a) that she shall use her best efforts and exercise utmost

         confidential and proprietary information, except as may be required in
         the course of her employment; and

                  (c) that she shall not use, directly or indirectly, for her

notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into her possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of her employment for any reason
whatsoever or at any other time upon request of the Board.

<PAGE>   65



processes ("Inventions") which she has now or may hereafter have during her
employment with the Company and which pertain or relate to the business of the
Company or to any experimental work, products, services or processes of the
Company in progress or planned for the future, whether conceived by the
Executive alone or with others and whether or not conceived during regular
working hours. All such Inventions shall be the exclusive property of the
Company. The Executive shall assist the Company, at any time during or after
her employment, in perfecting its rights in all Inventions and shall execute

business that is in competition in any manner whatsoever with the business of
the Company.

set forth in Paragraphs 8 and 9 of this Agreement shall continue to be binding
upon the Executive, notwithstanding the termination of her employment with the
Company for any reason whatsoever. Such covenants shall be deemed and construed
as separate agreements independent of any other provisions of this Agreement
and any other agreement between the Company and the Executive. The existence of
any claim or cause of action by the Executive against the Company, whether
predicated on this Agreement or otherwise, shall not constitute a defense to
the enforcement by the Company of any or all of such covenants. It is expressly
agreed that the remedy at law for the breach of any such covenant is inadequate

threatened breach thereof.

                  or injury absents herself from her duties without the consent

employment with the Company and which pertain or relate to the business of the
Company or to any experimental work, products, services or processes of the

and any other agreement between the Company and the Executive. The existence of

predicated on this Agreement or otherwise, shall not constitute a defense to
the enforcement by the Company of any or all of such covenants. It is expressly
agreed that the remedy at law for the breach of any such covenant is inadequate

         laws effective during the term hereof, such provision shall be fully

                         OPINION OF COUNSEL TO SELLERS

                    (Letterhead of Binkley & Steward, P.C.)


                                                 ____________, 1996


United Dental Care, Inc.
14755 Preston Road, Suite 300
Dallas, Texas 75240

Ladies and Gentlemen:

         We have acted as counsel to Gilbert G. Finger, Patricia L. Schubring,
Edward K. Halstead, Birchtree Enterprises and Binkley & Stewart, P.C.
(collectively, the "Sellers," and each, individually, a "Seller"), in
connection with the transactions contemplated by that certain Stock Purchase
Agreement (the "Agreement") , dated as of June 28, 1996, among United Dental
Care, Inc. ("Purchaser"), the Sellers, and Independent Dental Plans, Inc., a
Michigan corporation (the "Company"). This opinion is provided to you pursuant
to Section 9.1(f) of the Agreement.

         All defined terms used herein have the meanings set forth in the
Agreement, unless otherwise defined herein.

         In connection with the opinions rendered herein, we have reviewed
originals or copies of the following documents:

         (a) The Agreement and the Disclosure Schedules;

         (b) The Consulting Agreements between Schubring and Halstead,
respectively, and the Purchaser dated ____________, 1996 (the "Consulting
Agreements");

         (c) The Employment Agreements between Schubring and Halstead,
respectively , and the Company dated _____________________, 1996 (the
"Employment Agreements");

         (d) The Articles of Incorporation of the Company, certified by the
Secretary of State of Michigan on _____________, 1996;

         (e) Certificate issued by the Secretary of State of Michigan dated
______________, 1996 as to the good standing of the Company in Michigan;

United Dental Care, Inc.

Page 2




         (f) The Bylaws of the Company, certified as true, correct and complete
by the Secretary of the Company as of the date hereof;

         (g) The stock records of the Company; and

         (h) The corporate minute book of the Company containing the minutes of
all proceedings of the stockholders and directors of the Company.

         In rendering this opinion, with respect to factual matters, with your
permission and without independent investigation, we have relied upon
statements, factual representations, and certificates of officers, directors,
employees and agents of the Sellers and the Company, including, but not limited
to, the Certificate of Sellers and the President of the Company attached hereto
as as well as the representations and warranties of the Sellers contained in
the Agreement, and have assumed the continued accuracy of such factual matters
as of the date hereof. Additionally, we have relied, with your permission, upon
the certificates of public officials with respect, to the accuracy of the
factual matters contained therein and have assumed the continued accuracy of
such factual matters at the date hereof.

         In our examination of the foregoing specified documents and other
certificates, records and documents, we have assumed the genuineness of all
signatures, other than the Company and Sellers, the authenticity of all
documents submitted to us as original, the conformity with the original
documents of all documents submitted to us as certified, telecopied,
photostatic, conformed or reproduced copies, and the accuracy and completeness
of all corporate records and documents and of all certificates and statements
of fact, in each case given or made available to us by the Sellers or the
Company and their respective officers, directors, employees and agents. We have
also assumed the due authorization execution, delivery, accuracy, authenticity
and completeness of all certificates and documents provided to us by public
officials and all other persons or entities, other than the Sellers or the
Company.

         We have not been asked to express any opinion with respect to the
power and authority of any party to the Agreement, other than the Company and
the Sellers, to enter into, execute, deliver and perform the Agreement or
documents related thereto, or to effect the transactions therein contemplated,
or with respect to the application of any law or regulation to such power and
authority, and, for purposes of the opinions set forth below, we assume that
all parties other than the Sellers have all requisite power and authority under
all applicable laws, regulations and governing documents and have taken all
necessary corporate or other action required to be taken.

         In all instances where the opinions herein expressed are qualified to
the extent of our knowledge or to matters known to us, we have, with your
permission, relied solely upon the representations and warranties of the
Sellers contained in the Agreement and the Certificate of the Sellers and the
President of the Company attached hereto and our review of the documents set
forth in the second paragraph of this Letter. As used herein, "our current
actual knowledge," "our knowledge" and "matters known to us" are limited to
facts or information of which we are consciously aware.

         We call your attention to the fact that this firm requires only that
lawyers be qualified to practice law in the State of Michigan, and that we are
admitted to practice law only in the State of Michigan and the United States of
America. Accordingly, in rendering the opinions herein, we express no opinion
with respect to any laws other than the laws of the State of Michigan and the
United States of America, and we express no opinion with respect to federal
securities laws and regulations and state "blue sky" securities laws and
regulations.

         This opinion letter and the opinions expressed herein are limited by,
and in accordance with, the Legal Opinion Accord (the "Accord") of the ABA
Section of Business Law (1990).

         Subject to the foregoing and having due regard for the legal
considerations that we deem relevant, we are of the opinion that, giving effect
to the consummation of the transactions contemplated by the Agreement:

         1. The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Michigan, has all requisite
corporate power and authority to own, lease and operate its properties and
assets and to carry on its business as it is now being conducted.

         2. To our knowledge, each Seller has the requisite right, power,
authority and legal capacity to execute and deliver the Agreement and, with
respect to Schubring and Halstead, the Consulting Agreement and the Employment
Agreement, to perform his or her or its obligations thereunder and to
consummate the transactions contemplated thereby.

         3. The Agreement and, with respect to Schubring and Halstead, the
Consulting Agreement and the Employment Agreement has been duly executed and
delivered by the Company and each Seller and assuming the due authorization,
execution and delivery by the other parties thereto, constitute legal, valid
and binding obligations of the Company and each Seller enforceable against the
Company and each Seller in accordance with their respective terms and except as
limited by (i) the general qualifications, exceptions and limitations set forth
in the

<PAGE>   79


United Dental Care, Inc.
_______________, 1996
Page 4




Accord, (ii) matters of public policy and constitutional law, and (iii) as
otherwise noted or qualified by other parts of this opinion.

         4. The authorized capital stock of the Company consists of 50,000
shares of common stock, par value $1.00 per share (the "Common Stock"). The
stock record books and minute book reflect that 4,445 shares are issued and
outstanding and that each of the Sellers is the registered owner of the number
of shares set forth in Exhibit A to the Agreement. To our knowledge, the issued
and outstanding shares issued to the Sellers are held by them free and clear of
all Claims. All such outstanding shares of the Company are duly authorized,
validly issued and non-assessable. Additionally, there are no preemptive rights
attaching to the issued and outstanding shares which are contained in the
Articles of Incorporation or Bylaws. No shares of Common Stock are held as
treasury shares. To our knowledge, there are no outstanding options, warrants
or other rights (including registration rights), agreements, arrangements or
commitments of any character relating to the issued or unissued capital stock
of, or other equity interests in, the Company or obligating the Sellers or the
Company to grant, issue or sell any shares of the capital stock of, or other
equity interests in the Company, by sale, lease, license or otherwise. To our
knowledge, there are no voting trusts, shareholder agreements, proxies or other
agreements with respect to the voting or transfer of any shares of the capital
stock of, or other equity interests in, the Company.

         5. The execution and delivery of the Agreement, and the Consulting
Agreement and the Employment Agreement by Schubring and Halstead, do not and
will not, and the performance of the Agreement and the Consulting Agreement and
the Employment Agreement will not: (i) conflict with or violate the Articles of
Incorporation or Bylaws of the Company; (ii) conflict with or violate any law
or governmental order of the State of Michigan or the United States of America
applicable to any Seller or the Company or by which any of their or its assets,
properties or business is bound or affected; or (iii) result in any breach of
or constitute a default (or any event that, with notice or lapse of time or
both, would become a default) under, or give others any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of any
claims on any of the properties or assets of any Seller or the Company pursuant
to, any note, bond, mortgage, indenture, contract, agreement, lease, license,
permit, franchise or other instrument or obligations which is listed in the
Disclosure Schedules.

         6. Assuming Purchaser is a "bona fide purchaser" of the shares
purchased from each Seller upon delivery of the Shares to Purchaser endorsed to
it or in blank by the Sellers, Purchaser will acquire such shares free and
clear of any "adverse claim."

         7. The execution and delivery of the Agreement and the Consulting
Agreement and the Employment Agreement do not and will not, and the performance
of the Agreement and the Consulting Agreement and the Employment Agreement by
the Company and the Sellers shall not, require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
entity in Michigan, other than as has been already obtained, or to our
knowledge, any other state or any third party under any written material
contract which the Company or such Seller has listed in the Disclosure
Schedules and which is currently in force.

         8. To our knowledge, there is no claim, action, suit, litigation,
proceeding, arbitration, investigation or controversy of any kind naming as a
party any Seller or the Company, at law or in equity (including actions or
proceedings seeking injunctive relief), pending or threatened. To our
knowledge, none of the Sellers nor the Company is subject to any continuing
order of, consent decree, settlement agreement or other similar written
agreement with, or (other than routine audits or similar inquiries or
investigations conducted in the ordinary course) continuing investigation by,
any governmental entity, or any judgment, order, writ, injunction, decree or
award of any governmental entity, or arbitrator, including, without limitation,
cease-and-desist or other orders.

         Our opinions are based upon the law as currently in effect and
existing interpretations thereof. Insofar as our opinions relate to future
events or circumstances, our opinions expressed herein are based upon our
assumption that such laws and prevailing interpretations thereof will remain
unchanged. We assume no obligation to advise you of any changes in the
foregoing subsequent to the delivery of this opinion. This opinion has been
prepared solely for your use and may not be relied upon by any other person or
entity or governmental agency or quoted in whole or in part or otherwise
referred to or filed with or furnished to any other person or entity or used
for any other purpose without our prior written consent.

         WHEREAS, the Sellers were the owners of all the capital stock of IDP
and are executing this Release pursuant to the Stock Purchase Agreement as a
part of the consideration thereunder;

         NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the terms and
conditions hereof and other good and valuable consideration, the parties hereto
hereby agree as follows:

         1. Release. Subject to the provisions of Paragraph 2 hereof, each
Seller hereby unconditionally and irrevocably releases and forever discharges
the Company, IDP and all the respective direct or indirect subsidiaries of the
Company (the "Subsidiaries"), and their respective stockholders, directors,
officers, employees, successors and assigns of and from any and all rights,
claims, demands, judgments, obligations, liabilities, damages, losses,
attorney's fees, costs, expenses, actions, causes of action, and controversies
of any kind whatsoever, whether at law or in equity, statutory or common law,
accrued or unaccrued, fixed or contingent, asserted or unasserted, known or
unknown, relating to the Company or IDP or the Subsidiaries which ever existed,
now exist or may hereafter exist, by reason of any tort, breach of contract,
violation of law, act or failure to act, or any other matter or thing which
shall have occurred at or prior to the date of this Release including, without
limitation, any contractual or other obligation, loan, debt or liability of any
kind owed to the Seller by the Company or IDP on the date of this Release. The
parties hereto expressly intend that the foregoing release shall be effective
regardless of whether the basis for any claim or right released hereby shall
have been known or anticipated by the parties hereto. Notwithstanding the
foregoing or anything herein to the contrary, however, nothing herein is
intended to release or limit in any manner the rights or obligations of any
party with respect to the exceptions stated in Paragraph 2 hereof.

         2. Exceptions. Notwithstanding anything herein to the contrary, the
release stated in Paragraph 1 hereof shall not apply (i) to any rights which a

Company to under those certain Consulting Agreements and Employment Agreements
of even date herewith between IDP and such individuals entered into pursuant to

be illegal, invalid or unenforceable under laws now or hereafter in effect,
such provision shall be fully severable; this Release shall be construed and
enforced as if such provision had never comprised a part hereof; and the
remaining provisions of this Release shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance from this Release. In lieu of each such illegal, invalid or
unenforceable provision, there shall be added automatically as a part of this
Release a provision as similar in terms to such severed provision as may be
possible and be legal, valid and enforceable.

            (b) Survival. The provisions of this Release shall survive the

the same shall include the plural where appropriate, and words of any gender

            (e) Waivers. No waiver of any provision hereof shall be valid or
enforceable unless such waiver is in writing and signed by the party hereto
giving such waiver.

            (f) Intent of the Parties. The purpose and intent of this Release is
the termination and discharge of all disputes, controversies, claims, debts and
causes of action which exist or could exist as of the date hereof between the
Company and/or IDP and/or the Subsidiaries and a Seller, except as otherwise
specifically provided in Paragraph 2 hereof, and this Release shall be
interpreted and construed broadly so as to accomplish such purpose and intent.

            (g) Acknowledgment. The Sellers acknowledge that each of them has 
read and fully understands all of the provisions of the Release, and recognize
and acknowledge that 



                                       2

Company, IDP and the Subsidiaries subject only to the exceptions stated in
Paragraph 2 hereof.

            (h) Counterparts. This Release may be executed in two or more

for issuance and has no treasury shares.  There are no outstanding options,
warrants, convertible instruments, or other rights, agreements, or commitments
to issue or acquire any shares of common stock or any other security
constituting, or convertible or exchangeable into, capital stock of the
Company.  Since the date of the Company Balance Sheet, no shares of the
Company's capital stock, no options, warrants, or other rights, agreements, or
commitments (contingent or otherwise) obligating the Company to issue shares of
capital stock, and no other securities or instruments convertible or
exchangeable into shares of capital stock, have been executed or issued by the
Company.  The Company has not granted and is not a party to any agreement
granting preemptive rights, rights of first refusal, or registration rights

agency or indemnity agreement applicable to the issuance of shares of its
capital stock after the Effective Date.

       3.8     Licenses/Compliance with Law.  The Company has the lawful
authority and all federal, state or local governmental authorizations,
certificates of authority, licenses or permits necessary for or required to
conduct its respective business as such is presently being conducted.  Schedule
3.8 contains a list and description of all authorizations, certificates of
authority, licenses and permits, including those granted or derived from
governmental sources, issued or granted to the Company.  For the proper conduct
of its business, the Company is not required to obtain any additional
certificates of authority, permits, licenses or similar authorizations from any
governmental authority other than has already obtained as listed on Schedule
3.8.  There are no pending or, to the knowledge of the Seller, threatened
legal, administrative, arbitration or other actions, notices, or proceedings
and no pending or, to the knowledge of the Seller, threatened governmental
investigations by any federal, state or local government or any subdivision
thereof or by any public or private group which assert or allege any violation
of or non-compliance with any governmental requirements or which would have the
effect of limiting, prohibiting or changing the business operations of the
Company as authorized by the authorizations, certificates of authority,
licenses and permits set forth on Schedule 3.8 and as presently conducted by
the Company.  The Company maintains statutory reserves that satisfy the
requirements of all applicable governmental laws, rules and regulations
applicable to the Company, if any.  The Company has made all filings with
governmental agencies required for the conduct of its respective business
including, without limitation, to the extent applicable all annual reports, all
holding company statements required to be filed with insurance or similar





                                       4
<PAGE>   11
regulatory agencies and all filings required to conduct its business operations
as presently conducted by the Company.  There are no judgments against the
Company, and no orders, rules, consent decrees or injunctions of any court,
governmental department, commission, agency or instrumentality by which the
Company is bound or to which the Company is subject.  The Company has not
entered into and is not subject to any judgment, consent decree, compliance
order or administrative order with respect to any insurance, health maintenance
organization or other similar law or received any request for information,
notice, demand letter, administrative inquiry or formal or informal complaint
or claim with respect to any insurance or other similar law or the enforcement
of any such law.  Neither the Company's operations nor any of the assets owned,
leased, occupied or used by the Company in the operation of its business
materially violates or fails to comply in any material respect with any
applicable federal, state or local insurance, health maintenance organization,
or dental referral plan statutes, laws, rules or regulations or, to the
knowledge of Seller, any applicable federal, state or local health, fire,
environmental, safety, zoning, building or other codes, laws, rules or
regulations, and the Company has not received any notice of any alleged
violations thereof.

       3.9     Financial Statements.  The Company has delivered to Purchaser
a copy of (i) the unaudited financial statements of the Company as of December
31, 1993, 1994 and 1995 consisting in each case of a balance sheet at each such
respective date, and the related statements of income, changes in stockholders'
equity and cash flows for the applicable twelve (12) month period then ended
and (ii) unaudited financial statements of the Company as of June 30, 1996 (the
"Balance Sheet Date") consisting of a balance sheet of the Company at such date
(the "Company Balance Sheet") and the related statements of income, changes in
stockholders' equity and cash flows for the applicable month and year-to-date
period then ended.  Complete and accurate copies of all such financial
statements are attached as a part of Schedule 3.9 (the "Financial Statements").
The Financial Statements present fairly in all material respects the financial
position of the Company, and the results of the operations, changes in
stockholders' equity and cash flows of the Company, as of the respective dates
thereof and for the respective periods covered thereby, in conformity with
generally accepted accounting principles ("GAAP").  Except as set forth in the
Company Balance Sheet included in the Financial Statements, as of the Balance
Sheet Date there were no liabilities, debts, claims or obligations, whether
accrued, absolute, contingent or otherwise, whether due or to become due, which
are required by GAAP to be set forth in a balance sheet of the Company which
have not been so set forth in the Company Balance Sheet.  The Financial
Statements were prepared from the books and records of the Company.  There are
no assets shown on the Company Balance Sheet which are valued thereon at an
amount materially in excess of their fair value as of the Balance Sheet Date.
At the Balance Sheet Date, the Company owned each of the assets included in the
Company Balance Sheet.  From the date hereof through the Closing Date, the
Company will continue to prepare monthly and year-to-date unaudited financial
statements on the same basis and will promptly deliver the same to Purchaser.
The foregoing representations will be applicable to all such monthly unaudited
financial statements so prepared and delivered.

since the Balance Sheet Date, the business of the Company has been conducted
only in the ordinary course and there has not been (i) any material adverse
change in the financial condition, business,





                                       5
<PAGE>   12
properties, assets, or results of operations of the Company (financial or
otherwise) exclusive of any general economic factors affecting the prepaid
dental plan industry in general; (ii) any material loss or damage (whether or
not covered by insurance) to any of the assets of the Company which materially
affects or impairs the ability of the Company to conduct its business as
previously conducted or any other event or condition of any character which has
materially and adversely affected the business or operations of the Company;
(iii) the attaching, placing or granting of, or the agreement to attach, place
or grant, any encumbrance on any of the assets of the Company; (iv) any sale or
transfer of any material portion of the assets of the Company; (v) any material
changes in the terms of any material contract of the Company; (vi) any material
change in the accounting systems, policies or practices of the Company; (vii)
any waiver by or on behalf of the Company of any rights which have any material
value; (viii) no taking under condemnation or right of eminent domain of any of
the assets of the Company; (ix) any entry into or termination of any material
commitment, contract, agreement, or transaction (including, without limitation,
any material borrowing or capital expenditure or sale or other disposition of
any material assets) by the Company; (x) any redemption, repurchase, or other
acquisition of any of its capital stock by the Company, or any issuance of
capital stock of the Company or of securities convertible into or rights to
acquire any such capital stock; (xi) any dividend or distribution declared, set
aside or paid on capital stock of the Company; (xii) any transfer or right
granted by the Company of or under any material lease, license, agreement,
patent, trademark, trade name, service mark or copyright; (xiii) any sale or
other disposition of any material asset of the Company, or any mortgage,
pledge, or imposition of any lien or other encumbrance on any material asset of
the Company, or any agreement relating to or contemplating any of the foregoing
not in the ordinary and usual course of business; (xiv) any default or breach
by the Company in any material respect under any contract, license, or permit;
or (xv) any material increase in the statutory reserves required to be
maintained by the Company.  Since the Balance Sheet Date, the Company has
conducted its business only in the ordinary and usual course of business and,
without limiting the foregoing, no changes have been made in (i) employee
compensation levels, (ii) the manner in which employees of the Company are

in any jurisdiction in which the Company operates.  The Company has not entered
into or been subject to any judgment, consent decree, compliance order or
administrative order with respect to any insurance or other similar law or,
other than in the ordinary course of business, received any request for
information, notice, demand letter, administrative inquiry or formal or
informal complaint or claim with respect to any insurance or other similar law
or the enforcement of any such law. As of the date hereof there is no, and
since the date of the Balance Sheet, the Seller has no knowledge of any,
legislative or regulatory development or written proposal relating to (i) any
statute, rule or regulation or other law not currently in effect or (ii) the
scope or application of any statute, rule, regulation or other law currently in
effect but not currently applicable so that, if enacted, promulgated or made
applicable to the Company or its business, may have or impose any additional
regulatory obligations or limitations on such Company or such Subsidiary or
their respective products.   In any jurisdiction in which the Company is
conducting or has, prior to the date hereof, ever conducted any activities
including without limitation activities relating to the
offer and sale of dental care products, plans or services, the recruitment of
dentists or dental offices in connection with the offer and sale of such
products, plans or services, the marketing of any such products plans or
services to potential purchasers or subscribers thereto, or any joint venture
with any other party relating to the foregoing, the Company has not failed to
comply with any applicable statute, ordinance, order, rule or regulation, or
failed to obtain any certificated authority, license or permit, which failure,
in either case, would subject such Company to any fine, penalty, assessment or
other amount or could be the basis for any judgment, consent decree, compliance
order or administrative order with respect to any insurance or similar law.
Seller shall be liable for any such fine, penalty, assessment or judgment, or
any liabilities incurred or payments required under any such consent decree,
compliance order or administrative order as a result of any





                                      15

Seller and Purchaser shall issue a press release regarding the execution of
this Agreement within one day of the date hereof or such other time as Seller

Purchaser of any changes, additions, or events which may cause any change in or
addition to the Schedules delivered by them under this Agreement promptly after
the occurrence of the same and again at the Closing by delivery of appropriate
updates to all such Schedules.  No notification of a change or addition to a
Schedule made pursuant to this Section shall be deemed to cure any breach of
any representation or warranty resulting from such change or addition unless
Purchaser specifically agrees thereto in writing, nor shall any such
notification be considered to constitute or give rise to a waiver by Purchaser
of any condition set forth in this Agreement.  Nothing contained herein shall
be deemed to create or impose on Purchaser any duty to examine or investigate
any matter or thing for the purposes of verifying the representations and

occur in the future as a result of any regulatory requirement or condition to

                 (d)      The representations and warranties of Seller set
forth in this Agreement shall be true in all material respects as of the date
of this Agreement and, except in such respects as do not materially and
adversely affect the business, condition (financial or otherwise), operations,
or prospects of the Company and the Subsidiaries, as of the Closing Time as if
made as of such time;

                 (e)      Purchaser shall have received from Seller a
certificate, dated the Closing Date, executed by Seller, and an officer's

       excess of insurance coverage maintained by the Company which would be
       applicable to such claim; provided, however, that, in the event that the
       parties cannot mutually agree as to whether any such litigation or claim
       is reasonably expected to have such potential liability to the Company,
       then the parties shall seek the opinion of a mutually selected third
       party qualified to make such assessment and the opinion of such third
       party as to such potential liability shall be binding upon the parties
       for the purposes hereof; and

                 (h)      At or prior to Closing, the Company shall have
received (and delivered copies thereof to Purchaser) duly executed resignation

amounts due from the Company to such respective individuals except as expressly
set forth in this Agreement.

                 (i)      None of the certificates of authority or licenses of
the Company listed on Schedule 3.8, if any, shall have been canceled, revoked
suspended or limited in any respect and no governmental regulatory agency shall
have instituted any proceeding, or given notice to the Company or a Subsidiary
that it intends to institute any proceeding to take such action or to place the

financial condition or failure to comply or satisfy any governmental law, rule
or regulation.

                 (j)      At the Closing, there shall simultaneously occur the

                 (k)      At or prior to the Closing, the Purchaser and both
United Group Association, a Texas corporation, and Cornerstone Marketing

executed and delivered Marketing Agreements pursuant to which each such entity
shall have agreed to market through its respective dedicated agents the dental
benefit products (i.e. dental indemnity insurance, prepaid dental plans and





                                      26
<PAGE>   33
dental preferred provider organization memberships) of Purchaser and its
affiliates.  The terms and conditions, including conversion schedules, must be
mutually satisfactory to both Purchaser and such respective entities.  It is
expressly understood that the negotiating, execution and delivery of both such
Marketing Agreements is a material condition precedent to the obligations of
Purchaser under this Agreement and must be satisfied at or prior to the
Closing.

                 (l)      At the Closing, the Seller shall perform the
respective obligations of and actions to be taken by all the Seller at the
Closing as described in Section 9.2 of this Agreement.

which all governmental and third party consents necessary for the consummation
of the transactions contemplated by this Agreement and the IDP Agreement and
the UDP Agreement are obtained and all other conditions to Closing are
satisfied (specifically including, without limitation, the condition specified
in Section 8.1(k)), but in no event later than one hundred fifty (150) days
after the Effective Date unless extended by the mutual agreement of the
Purchaser and the Seller, subject to earlier termination pursuant to the
provisions of Article 12 hereof.  In the event that the Closing does not timely
occur as stated above, then a party not in default may immediately terminate
this Agreement upon written notice to the other party in accordance with
Section 12.1 below; provided, however, that this Agreement shall terminate
automatically and without further notice if the Closing has not occurred within
one hundred fifty (150) days of the Effective Date unless extended by the
mutual agreement of the Purchaser and Seller.

       9.2       Actions by Seller.  At the Closing, Seller shall:

                 (a)      Stock.  Deliver to Purchaser the original
certificates representing the Shares owned by such Seller duly endorsed for
transfer or with appropriate stock powers with respect thereto duly endorsed in
blank by such Seller, with such signature guarantee and such other documents as
may be reasonably required to effect a valid transfer of the Shares to
Purchaser, free and clear of any and all claims.

                 (b)      Other Agreements.  Perform or shall have performed
all of the covenants and agreements contained in this Agreement to be performed
or complied with by such Seller at or prior to the Closing hereunder.

       9.3       Actions by Purchaser.  At the Closing, Purchaser shall:

                 (a)      Payment.  Pay the Purchase Price to the Seller in

Purchaser less, however, the amount of the Earnest Money paid to the Seller and
credited against the Purchase Price pursuant to the Escrow Agreement.

                 (b)      Other Agreements.  Perform or shall have performed
all of the covenants and agreements contained in this Agreement to be performed

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       10.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this Agreement
shall be true at the Closing and shall survive the consummation of this
Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
indemnification with respect to losses relating to Taxes shall expire six (6)
months after the termination of the applicable statute of limitations and
providing further, however, that if, prior to the expiration of such two year
period, a state of facts shall have become known which threatens to give rise to
a liability against which any party hereto would be entitled to indemnification
hereunder and the indemnified party shall have given notice of such facts to the
indemnifying party, then the rights of the indemnified party to indemnification
with respect to such liability shall continue until such liability shall have
been finally determined and disposed of (including and subject to disposition by
the expiration of the applicable statute of limitations with respect to such
liability); and provided further, however, that, if a claim for indemnification
is made pursuant to this Article 10, then such claim for indemnification or any
claim arising out of the wrongful failure to comply with the provisions of this
Article 10 shall survive until the expiration of the applicable period of
limitations with respect to such claim for indemnification; and provided
further, however, that such two year limitation specified above shall not apply
to the extent provided otherwise in Section 10.4(c) below.  With respect to the
representations and warranties of the parties, such representations and
warranties shall be true as of and at the date of the Closing but nothing
contained herein shall be deemed to require or imply that the accuracy of such
representations and warranties shall apply on a continuing basis as to facts
existing after the date of the Closing.  Except to the extent set forth herein,
no investigation or examination made by any party hereto shall constitute a
waiver of any representation or warranty and no representation or warranty shall
be merged into the Closing hereunder.  However, to the extent information is
apparent on the face of the Schedules or is otherwise expressly set forth
herein, such information shall be deemed to amend,
        




                                      28
<PAGE>   35
limit and/or restate any representation and warranties contained herein to the
extent such information is inconsistent with such representation or warranty.

       10.2      Indemnity.  Subject to the provisions of Section 10.4 below,

                 (a)      Seller.  Seller agrees to indemnify and hold harmless
the Company and Purchaser, and their respective shareholders, partners,
directors, officers, employees and agents, from, against, and in respect of,
any loss, liability, claim, demand, or expense, including but not limited to
attorney, investigation and consultant fees and costs, and of any other kind
whatsoever arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Seller under this Agreement
       or under any other agreement or document delivered by the Seller at
       Closing hereunder; and

                 (ii)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold Seller
harmless from, against, and in respect of, any loss, liability, claim, demand,
or expense, including but not limited to attorney's fees and costs, of any kind
whatsoever, arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Seller at Closing hereunder;

                 (ii)     Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Seller are obligated to indemnify and hold the 
       Purchaser harmless pursuant to Section 10.2(a) above; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       10.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
10.2(a) or 10.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might result in any such claim, demand or
action, such party shall promptly notify the other party or parties who would
be obligated to provide indemnity hereunder with respect to such claim, demand
or action, and such other party or parties shall have the right to take such
action as it or they may deem appropriate to resolve such matter.  The
indemnified party or





                                      29
<PAGE>   36
parties shall have the right to employ  separate counsel in any such action and
to participate in the defense thereof, but the fees and expenses of such
counsel shall be at the expense of such indemnified party or parties, unless
the employment of such counsel has been specifically authorized by the
indemnifying party or parties.  Any settlement of any action subject to
indemnity hereunder shall require the consent of the indemnified and the
indemnifying party which consent shall not be unreasonably withheld and shall
be given within five (5) days following the giving of notice thereof.  The
indemnifying party or parties shall not be liable for any settlement of any
action effected without its or their consent, but if settled with the consent
of the indemnifying party or parties or if there be a final judgment for the
plaintiff in any such action, the indemnifying party or parties shall indemnify
and hold harmless the indemnified party from and against any loss or liability
by reason of such settlement or judgment.  If requested by the indemnifying
party, the indemnified party shall cooperate with the indemnifying party and
its counsel and use its best efforts in contesting any such claim or, if
appropriate, in making any counter-claim or cross-complaint against the party
asserting the claim, provided that the indemnifying party will reimburse the
indemnified party for reasonable expenses incurred in so cooperating upon
presentation of receipts or other evidence of such expense.  The indemnifying
party and its representatives shall have full and complete access during
reasonable business hours to all books, records and files of the indemnified
party expressly related to the defense of any claim for indemnification
undertaken by the indemnifying party pursuant to this Article 10, or for any
other purpose in connection therewith; provided that the indemnifying party
shall safeguard and maintain the confidentiality of all such books, records and
files.

       10.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Seller nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Twenty-Five
Thousand Dollars ($25,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms hereof; provided, however, that the
$25,000 limitation set forth in this Section 10.4(a) shall not apply to the
matters described in Section 10.4(c).

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 10.1 and this Section 10.4(b) shall not apply
to the matters described otherwise in Section 10.1 or in Section 10.4(c) as to
which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party shall have given notice of such facts to the indemnifying
party and made a claim for indemnification within such two-year period, then
the right to indemnification with respect thereto shall remain in effect until
such matter shall have been finally determined and disposed of and any
indemnification due in respect thereof shall have been paid.





                                      30
<PAGE>   37
                 (c)      Certain Matters.   The following are the
matters referred to in Section 10.4(a) and Section 10.4(b):

                 (i)      Losses arising from fraud or an intentional
misrepresentation on the part of the Seller; and

                 (ii)     Losses arising from the intentional breach of any
       covenant or agreement by the Seller contained in this Agreement.

       10.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 10
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Seller and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       10.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.

       10.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 3.24 with the appropriate governmental  or regulatory
agencies within ten (10) business days of the Effective Date.



                                   ARTICLE 11
                                NON-COMPETITION

       11.1      Covenant Not to Compete; Non-Solicitation.  For and in
consideration of the purchase by the Purchaser of the Shares pursuant to this
Agreement, and the payments payable by the Purchaser pursuant to this
Agreement, Seller covenants and agrees that it shall not, directly or
indirectly, through its officers, employees, agents or representatives as an
employer, consultant, creditor, investor, owner, agent, principal, partner,
shareholder, or through any other kind of ownership (other than ownership of
securities of any publicly held entity in which the Seller, directly or
indirectly, in the aggregate beneficially owns less than two percent (2%) of
any class of outstanding securities), or in any other representative or
individual capacity, do any of the following:





                                      31
<PAGE>   38
                 (i)      for a period of three (3) years from the date of this
       Agreement, engage in the solicitation of any of the prepaid dental
       customers or dental preferred providers of the Purchaser or its
       affiliates for the benefit of any prepaid dental plan or dental
       preferred provider organization other than an affiliate of Purchaser in
       the continental United States (the "Restricted Area");

                 (ii)     for a period of three (3) years from the date of this
       Agreement, engage in any business which calls upon, solicits, diverts or
       takes away any customer or customers of the Company in the Restricted
       Area for the purpose of selling or attempting to sell to any of said
       customers any products or services similar to any products or services
       heretofore sold or provided to any of such customers by the Company; and

                 (iii)    for a period of five (5) years from the date of this
       Agreement, engage in any business which solicits any present or future
       employee of the Company or initiates discussions with any such employee
       regarding his or her termination or resignation from employment with the
       Company, so that such employee may accept employment with, or engagement
       as a partner, investor, shareholder, employee, agent or consultant with
       Seller, directly or indirectly, as specified above; provided, however,
       that Seller shall not be prohibited by this Agreement from employing or
       soliciting the employment of any employee that the Company terminates
       after the date of such termination.

It is expressly understood that it shall not be deemed a violation of this
Section 11.1 in the event that, pursuant to an agreement with the Purchaser or
the Company, agents of the Seller solicit business on behalf of the Company or
other affiliates of Purchaser after the Closing Date.

                 11.2     Permitted Activities.  Seller shall have the right,
upon the completion of the sale of the Company to Purchaser, to continue to
market and sell its back-office, claims and other operational applications
involving technology solutions to dental organizations and companies of all
types, whether or not they compete with Purchaser.  Additionally, nothing
contained herein shall be construed to limit, excuse or prohibit Seller from
marketing life, health (excluding dental), annuity, vision or drug products to
Purchaser's customers or providing third party administration to self-insured
accounts.

                 11.3     Non-Disclosure.  Seller covenants and agrees that all
information concerning the Company, including without limitation (i)
information regarding prices or premiums charged for products and services,
(ii) the assets, liabilities and financial condition of the Company and its
subsidiaries, (iii) the names and identities of customers and analyses of the
amount and types of products and services purchased by each such customer, (iv)
the dental health providers utilized by the Company and its subsidiaries and
the financial arrangements with such providers, and (v) the amount of
compensation to employees, constitute trade secrets and confidential,
proprietary business information which is the property of the Company and that,
unless otherwise required by law, from and after the date of this Agreement:

                 (a)      Seller shall use its best efforts and exercise utmost
       diligence to protect and safeguard all of such trade secrets and
       confidential, proprietary information;





                                      32
<PAGE>   39
                 (b)      Seller shall not, directly or indirectly, use, sell,
       license, publish, disclose or otherwise transfer or make available to
       others any of such trade secrets or confidential, proprietary
       information;

                 (c)      Without the prior written consent of the Company,
       Seller shall not, directly or indirectly, disclose any of such trade
       secrets or confidential, proprietary information; and

                 (d)      Seller shall not, directly or indirectly, use for its
       own benefit or for the benefit of another, any of such trade secrets or
       confidential, proprietary information.

It is expressly understood, however, that the foregoing shall not apply to any
information that was generally available to the public on a non-confidential
basis prior to the date of this Agreement or was or becomes generally available
to the public on a non-confidential basis from a third party who is not bound
to keep such information confidential.

         11.4    Nondisparagement.  For a period of three (3) years and after
the date of this Agreement, Seller further agrees that it shall not make or
publish any statement, written or oral, disparaging the reputation of the
Company or its subsidiaries, executive officers or any of its business services
or products or solicit or encourage any member of any prepaid dental plan of
the Company or its subsidiaries or any third party having a group agreement
with the Company or its subsidiaries to terminate the membership of such person
in the plan of the Company or its subsidiaries or to terminate such group
agreement.

         11.5    Reasonableness; Reformation.  Seller acknowledges and agrees
that (i) the provisions of this Article 11 are ancillary to the transaction
pursuant to which the Seller sold and the Purchaser acquired the Shares, (ii)
the provisions of this Agreement contain reasonable limitations as to time,
geographical area and scope of activities to be restrained and do not impose a
greater restraint than is necessary to protect goodwill and other business
interests of the Company and its subsidiaries, (iii) if any portion of the
covenants and agreements set forth in this Agreement are held to be invalid,
unreasonable, arbitrary or against public policy, then such portion of such
covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, and (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against public policy, a lesser time
period, scope of activities covered, and/or geographical area which is
determined to be reasonable, non-arbitrary and not against public policy may be
enforced against Seller.

         11.6    Remedies for Breach.  If Seller has failed to satisfactorily
cure any breach or threatened breach of any covenant or agreement contained
herein within ten (10) days after written notice of such breach or threatened
breach given by the Purchaser to Seller, any one or more of the following
remedies, as selected by the Purchaser in its sole discretion, shall be
available to the Purchaser in the event of a breach of this Agreement by Seller
hereunder:

                 (a)      Specific Performance.  In the event of a breach or
         threatened breach of any covenant or agreement of Seller in this
         Agreement, remedies at law will not adequately compensate the
         Purchaser for its injuries incurred as a result  thereof.
         Accordingly, injunctive and/or equitable relief shall be available to
         the Purchaser to specifically enforce this Agreement and prevent such
         breach and any continued breach of any covenant and agreement herein.
         Seller agrees that a bond of no more than $10,000 in the aggregate
         will provide adequate protection to Seller and therefore no more than
         $10,000 in bond or other security shall be required to be posted by
         the Company by any court in any proceeding to obtain such injunctive
         or equitable relief.

                 (b)      Suit for Damages.  In addition to the remedies stated
         in Section 11.5(a) above, in the event of any breach of any covenant
         or agreement of Seller herein, Purchaser may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Seller under applicable law.

                              TERMINATION; WAIVER

         12.1    Termination.  This Agreement may be terminated, and the
transaction may be abandoned, at any time prior to the Closing,  as follows and
in no other manner:

                 (a)      Mutual Consent.  By the mutual consent of Purchaser
and the Seller;

                 (b)      By Purchaser or Seller: Condition Precedent.  By
Purchaser or Seller, upon written notice to the other, if the conditions to the
obligations of such canceling party or parties to consummate the transaction,
in the case of the Seller, as provided in Article 7 or, in the case of
Purchaser, as provided in Article 8, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this
Agreement unless the failure of the condition is the result of the material
breach of this Agreement by the party seeking to terminate; provided, however,
that, in the event all such conditions have been satisfied except solely the
condition with respect to obtaining all required consents, authorizations, and
approvals of governmental and regulatory agencies set forth in Sections 7.1(a)
and 8.1(a), respectively, and such failure is not due to a breach of this
Agreement by the non- terminating party, such date shall be automatically
extended for one thirty (30) day period; provided, however, that in no event
shall such date be extended beyond an aggregate of one hundred fifty (150) days
after the date of this Agreement unless extended by the mutual agreement of the
Purchaser and the Seller;

                 (c)      By Purchaser or Seller: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Seller, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party





                                      34
<PAGE>   41
notifies the other in writing of such default or breach, specifying the nature
thereof or (y) one hundred fifty (150) days after the date of this Agreement,
unless such date is extended by mutual agreement of Purchaser and Seller.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Seller,
Seller shall be entitled to retain the Earnest Money.  Any public announcement
of the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

         12.2    Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Seller, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

written agreement executed by Purchaser and Seller.

         14.4    Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any affiliate of
Purchaser without the necessity of seeking the consent of the Seller; provided,
however, that Purchaser shall not be relieved of any obligations as a result of
such assignment and that, in addition to Purchaser remaining liable, any such
assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  The Seller shall not be entitled to assign

                                      38

however, that the rights and obligations of Seller may be assigned by operation

not relieve or release Seller of any obligations hereunder as a result of such
assignment and that, in addition to such Seller remaining liable, any such
assignee shall assume and become liable for any and all of Seller's obligations
under this Agreement. In connection with any such assignment, Seller may
transfer all or any portion of the Shares owned by the Seller and thereby
effect an assignment on the basis specified above.

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

         14.7    Headings/Captions.  The captions to sections and subsections

provisions of this Agreement.

         14.8    Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

         14.9    Attorney's Fees and Costs.  In the event of a breach by any
party to this Agreement and commencement of a subsequent legal action in a
court of law or forum of arbitration, or in the event legal counsel is
consulted in the event of any such breach or in anticipation of any such
prospective legal action, the prevailing party in any such dispute shall be
entitled to reimbursement of reasonable attorney's fees and court costs,
including, but not limited to, the costs of expert witnesses, transportation,
lodging and meal costs of the parties and witnesses, costs of transcript
preparation and other reasonable and necessary direct and incidental costs of
such dispute.  "Prevailing party" is the party in whose favor final judgment is
rendered.

         14.10   Time.  Time is of the essence under this Agreement.

counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                                   EXHIBIT A

                         EARNEST MONEY ESCROW AGREEMENT


         This Earnest Money Escrow Agreement (the "Agreement") is made as of
the 10th day of September, 1996 among UICI, a  Delaware corporation ("Seller");
United Dental Care, Inc., a Delaware corporation ("Purchaser"); and Texas
Commerce Bank National Association (the "Escrow Agent").

         WHEREAS, Seller and Purchaser have entered into that certain Stock
Purchase Agreement dated September 10, 1996 (collectively the "Stock Purchase
Agreement") providing for the purchase of all the issued and outstanding shares
of capital stock (collectively the "Shares") of Association Dental Plan, Inc.,
a District of Columbia corporation ("ADP") (ADP being sometimes collectively
referred to herein as the "Company") from the Seller by Purchaser; and

         WHEREAS, in connection with the execution of the Stock Purchase
Agreement, Purchaser has agreed to place the sum of Two Hundred Thirty Thousand
and no/100ths Dollars ($230,000) in escrow and for the purposes hereinafter set
forth.  (Such escrow deposit and any interest earned thereon while such funds
are in escrow are referred to herein as the "Escrow Money"); and

         WHEREAS, the parties desire to effectuate the provisions of the Stock
Purchase Agreement with respect to the Escrow Money;

         NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the mutual terms
and conditions hereof, the parties hereby agree as follows:

         1.      Escrow Money.  Simultaneously with the execution of this
Agreement, Purchaser has deposited the sum of $230,000 in immediately available
funds with the Escrow Agent, the receipt of which is hereby acknowledged by the
Escrow Agent by its execution hereof.

         2.      Escrow Account.  The Escrow Money shall be held in escrow by
the Escrow Agent pursuant to the terms and conditions of this Agreement.  Upon
receipt of the Escrow Money,  the Escrow Agent shall place the Escrow Money
deposit into a non-interest bearing escrow account (the "Escrow Account") under
the following terms and conditions: (i) at the Escrow Agent; (ii) under the
name of Texas Commerce Bank National Association, as Escrow Agent and (iii)

<PAGE>   2
Institutional Cash Portfolio-Treasury Fund Number 695.  It is understood and
agreed that the Escrow Agent will be issuing a 1099 INT statement to the
Purchaser and the Internal Revenue Service, even though the interest may be
payable eventually to either the Purchaser or the Seller as the case may be. 
In the event the interest is paid to the Purchaser, the Purchaser shall have
the responsibility as to any 1099 INT reporting thereof.  The Escrow Money
shall at all times be held in the Escrow Account and shall only be delivered
pursuant to the terms and conditions of this Agreement.

         3.      Terms of Escrow.  The Escrow Money shall only be applied by
the Escrow Agent in accordance with the following terms and directions:

                 (a)      Application upon Closing.  In the event that the
         Seller has not furnished written notice to Purchaser and the Escrow
         Agent of the failure of Purchaser to consummate the Stock Purchase
         Agreement in accordance with Section 3(b) below prior to Closing under
         the Stock Purchase Agreement, then, upon the Closing, Escrow Agent
         shall receive a notice executed by Purchaser and Seller directing
         Escrow Agent to either (i) pay the Escrow Money to Seller as the
         notice shall direct in which case the Escrow Money shall constitute a
         credit against the Purchase Price or (ii) refund the Escrow Money to
         the Purchaser in which case it shall not constitute a credit against
         the Purchase Price.

                 (b)      Application upon Termination.  If Purchaser fails to
         consummate the Stock Purchase Agreement for any reason other than (i)
         a material breach of the Stock Purchase Agreement or this Agreement by
         Seller or (ii) the valid exercise of any right of termination by

         Agent of Purchaser's failure to consummate the Stock Purchase
         Agreement and directing that the Escrow Money be paid to the Seller.

         4.      Liability of Escrow Agent.  Purchaser and Seller hereby agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and amenities of the Escrow Agent:

                 (a)      The Escrow Agent is not a party to, and is not bound
         by, or charged with notice of, any agreement out of which this escrow
         may arise.

                 (b)      The Escrow Agent acts hereunder as a depository only,
         and is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or deposition the escrow or for any loss on any investment
         made pursuant to the provisions hereof.

                 (c)      The Escrow Agent shall be protected in acting upon
         any written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other paper or document which the
         Escrow Agent in good faith believes to be genuine and what it purports
         to be.

                 (d)      Purchaser and Seller, jointly and severally, agree to
         indemnify and hold the Escrow Agent harmless against any and all
         losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non- performance
         of its duties hereunder whether such losses, claims, demands,
         liabilities and expenses arise during or subsequent to performance of
         this Agreement, directly or indirectly, excluding, however, any such
         liability resulting from its gross negligence or willful misconduct.
         In the event the Escrow Agent becomes involved in litigation in
         connection with this escrow, Purchaser and Seller, jointly and
         severally, agree to indemnify and save the Escrow Agent harmless from
         any and all losses, claims, damages, liabilities and expenses,
         including attorney's fees and costs, interpleader costs and judgments,
         which may be incurred or suffered by Escrow Agent as a result thereof,
         excluding, however, any such liability resulting from its gross
         negligence or willful misconduct. It is the express intent of the
         Purchaser and the Seller to indemnify and hold the Escrow Agent
         harmless against its own ordinary negligence.

                 (e)      In the event of any disagreement between any of the
         parties to this Agreement or with any third person resulting in
         adverse claims or demands being made in connection with the Escrow
         Money, or in the event the Escrow Agent in good faith is in doubt as
         to what action it should take hereunder, the Escrow Agent may, at its
         option, refuse to comply with any claims or demands on it, or refuse
         to take any other action hereunder, so long as such disagreement
         continues or doubt exists, and in such event, the Escrow Agent shall
         not be or become liable in any way or to any person for its failure or
         refusal to act, and the Escrow Agent shall be entitled to continue to
         so refrain from acting until (i) the rights of all the parties shall
         have been fully and finally adjudicated by a court of competent
         jurisdiction, or (ii) all differences shall have adjusted





                                       3
<PAGE>   4
         and all doubt resolved by agreement among all the interested parties
         and the Escrow Agent shall have been notified thereof pursuant to
         written directions duly executed by all such persons.  In the event of
         conflicting demands on the Escrow Agent, the Escrow Agent may, at its
         option, deposit any and all funds in question with the court that
         would have jurisdiction over the matter, and in such event, the Escrow
         Agent is relieved of any further responsibility in connection with
         this escrow.

                 (f)      Escrow Agent may consult with its counsel or other
         counsel satisfactory to it concerning any question relating to its
         duties or responsibilities hereunder or otherwise in connection
         herewith, and shall not be liable for any action taken, suffered or
         omitted by it in good faith upon the advice of such counsel.

                 (g)      Escrow Agent may resign hereunder upon thirty (30)
         days' prior notice to the Seller and Purchaser.  Upon the effective
         date of such resignation, Escrow Agent shall deliver the Escrow Money
         to any substitute escrow agent designated by Seller and Purchaser in
         writing.  If Seller and Purchaser fail to designate a substitute
         escrow agent within thirty (30) days after the giving of such notice,
         Escrow Agent may institute a petition for the appointment of a
         successor escrow agent hereunder.  Escrow Agent's sole responsibility
         after such 30-day notice period expires shall be to hold the Escrow
         Money (without any obligation to reinvest the same) and to deliver the
         same to a designated substitute escrow agent, if any, or in accordance
         with the directions of a final order or judgment of a court of
         competent jurisdiction, at which time of delivery Escrow Agent's
         obligations hereunder shall cease and terminate.

         5.      Compensation of Escrow Agent.  As compensation for its
services hereunder, the Escrow Agent shall be entitled to the fees and expenses
set forth on Schedule 1 hereto.  All fees and expenses of the Escrow Agent
shall be paid equally by the Seller and the Purchaser.

         6.      Non-Waiver.  Nothing contained in this Agreement shall be
deemed or construed to release or waive any of the rights or obligations of
Purchaser or Seller under the Stock Purchase Agreement, all rights and remedies
of Purchaser and Seller under this Agreement are cumulative of all other rights
which either of them may have under the Stock Purchase Agreement, by law or
otherwise.

         7.      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to
such other party(ies) at the address set forth below, and by (i) depositing the
same so addressed, postage prepaid, first class, certified or registered, in
the United States mail, return receipt requested (herein referred to as

Mailing the original.  Any notice shall be deemed to have been given five (5)
U.S. Post Office delivery days following the date of Mailing; one day after
timely delivery to an overnight courier; if by personal delivery, upon such
delivery; or if by facsimile, the day of transmission

assertion of rights, including condemnation, by any party, governmental or
other, and no proceedings with respect thereto have been instituted of which
the Seller has notice, that would materially affect the ability of the Company
to utilize each of such assets in its business.  The Company has not received
any notices of default or other violations from any mortgagee regarding any
properties leased by the Company.  Schedule 3.12 hereto contains a detailed
listing of all material assets of the Company.  The assets now owned by the
Company constitute all assets reasonably necessary to enable Purchaser to

condition, except for normal wear and tear.

products and other services offered and sold by the Company have been and are
offered and sold in compliance with the requirements of all relevant laws and

venture with any other party relating to the foregoing, the Company has not
failed to comply with any applicable statute, ordinance, order, rule or
regulation, or failed to obtain any certificate of authority, license or

<PAGE>   22
judgment, consent decree, compliance order or administrative order with respect

Schedule made pursuant to this Section shall be deemed to cure any breach of
any representation or warranty resulting from such change or addition unless
Purchaser specifically agrees thereto in writing, nor shall any such
notification be considered to constitute or give rise to a waiver by Purchaser
of any condition set forth in this Agreement.  Nothing contained herein shall
be deemed to create or impose on Purchaser any duty to examine or investigate
any matter or thing for the purposes of verifying the representations and

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       10.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
indemnification with respect to losses relating to Taxes shall expire six (6)
months after the termination of the applicable statute of limitations and
provided further, however, that if, prior to the expiration of such two year
period, a state of facts shall have become known which threatens to give rise
to a liability against which any party hereto would be entitled to
indemnification hereunder and the indemnified party shall have given notice of
such facts to the indemnifying party, then the rights of the indemnified party
to indemnification with respect to such liability shall continue until such
liability shall have been finally determined and disposed of (including and
subject to disposition by the expiration of the applicable statute of
limitations with respect to such liability); and provided further, however,
that, if a claim for indemnification is made pursuant to this Article 10, then
such claim for indemnification or any claim arising out of the wrongful failure
to comply with the provisions of this Article 10 shall survive until the
expiration of the applicable period of limitations with respect to such claim
for indemnification; and provided further, however, that such two year
limitation specified above shall not apply to the extent provided otherwise in
Section 10.4(c) below.  With respect to the representations and warranties of
the parties, such representations and warranties shall be true as of and at the
date of the Closing but nothing contained herein shall be deemed to require or
imply that the accuracy of such representations and warranties shall apply on a
continuing basis as to facts existing after the date of the Closing.  Except to
the extent set forth herein, no investigation or examination made by any party
hereto shall constitute a waiver of any representation or warranty and no
representation or warranty shall be merged into the Closing hereunder.
However, to the extent information is apparent on the face of the Schedules or

to the extent such information is inconsistent with such representation or
warranty.

<PAGE>   35
                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Seller under this Agreement
       or under any other agreement or document delivered by the Seller at
       Closing hereunder; and

                 (ii)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold Seller
harmless from, against, and in respect of, any loss, liability, claim, demand,
or expense, including but not limited to attorney's fees and costs, of any kind
whatsoever, arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Seller at Closing hereunder;

                 (ii)     Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Seller are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 10.2(a) above; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       10.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
10.2(a) or 10.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might result in any such claim, demand or
action, such party shall promptly notify the other party or parties who would
be obligated to provide indemnity hereunder with respect to such claim, demand
or action, and such other party or parties shall have the right to take such
action as it or they may deem appropriate to resolve such matter.  The
indemnified party or parties shall have the right to employ  separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties, unless the employment of such counsel has been specifically authorized
by the indemnifying party or parties.  Any settlement of any action subject to
indemnity hereunder shall require the consent of the indemnified and the
indemnifying party which consent shall not be unreasonably withheld and shall
be given within five (5) days following the giving of notice thereof.  The
indemnifying party or parties shall not be liable for any settlement of any
action effected without its or their consent, but if settled with the consent
of the indemnifying party or parties or if there be a final judgment for the
plaintiff in any such action, the indemnifying party or parties shall indemnify
and hold harmless the indemnified party from and against any loss or liability
by reason of such settlement or judgment.  If requested by





                                       29
<PAGE>   36
the indemnifying party, the indemnified party shall cooperate with the
indemnifying party and its counsel and use its best efforts in contesting any
such claim or, if appropriate, in making any counter-claim or cross-complaint
against the party asserting the claim, provided that the indemnifying party
will reimburse the indemnified party for reasonable expenses incurred in so
cooperating upon presentation of receipts or other evidence of such expense.
The indemnifying party and its representatives shall have full and complete
access during reasonable business hours to all books, records and files of the
indemnified party expressly related to the defense of any claim for
indemnification undertaken by the indemnifying party pursuant to this Article
10, or for any other purpose in connection therewith; provided that the
indemnifying party shall safeguard and maintain the confidentiality of all such
books, records and files.

       10.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Seller nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Twenty-Five
Thousand Dollars ($25,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms hereof; provided, however, that the
$25,000 limitation set forth in this Section 10.4(a) shall not apply to the
matters described in Section 10.4(c).

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 10.1 and this Section 10.4(b) shall not apply
to the matters described otherwise in Section 10.1 or in Section 10.4(c) as to
which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party shall have given notice of such facts to the indemnifying
party and made a claim for indemnification within such two-year period, then
the right to indemnification with respect thereto shall remain in effect until
such matter shall have been finally determined and disposed of and any
indemnification due in respect thereof shall have been paid.

                 (c)      Certain Matters.  The following are the matters 
referred to in Section 10.4(a) and Section 10.4(b):

                 (i)      Losses arising from fraud or an intentional
       misrepresentation on the part of the Seller; and

                 (ii)     Losses arising from the intentional breach of any
       covenant or agreement by the Seller contained in this Agreement.

       10.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 10
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Seller and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       10.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.

       10.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 3.24 with the appropriate governmental or regulatory
agencies within five (5) business days of the Effective Date.

                                NON-COMPETITION

       11.1      Covenant Not to Compete; Non-Solicitation.  For and in
consideration of the purchase by the Purchaser of the Shares pursuant to this
Agreement, and the payments payable by the Purchaser pursuant to this
Agreement, Seller covenants and agrees that it shall not, directly or
indirectly, through its officers, employees, agents or representatives as an
employer, consultant, creditor, investor, owner, agent, principal, partner,
shareholder, or through any other kind of ownership (other than ownership of
securities of any publicly held entity in which the Seller, directly or
indirectly, in the aggregate beneficially owns less than two percent (2%) of
any class of outstanding securities), or in any other representative or
individual capacity, do any of the following:

                 (i)      for a period of three (3) years from the date of this
       Agreement, engage in the solicitation of any of the prepaid dental
       customers or dental preferred providers of the Purchaser or its
       affiliates for the benefit of any prepaid dental plan or dental
       preferred provider organizations other than an affiliate of Purchaser in
       the continental United States (the "Restricted Area");

                 (ii)     for a period of three (3) years from the date of this
       Agreement, engage in any business which calls upon, solicits, diverts or
       takes away any customer or customers of the Company in the Restricted
       Area for the purpose of selling or attempting to sell to





                                       31
<PAGE>   38
       any of said customers any products or services similar to any products
       or services heretofore sold or provided to any of such customers by the
       Company; and

                 (iii)    for a period of five (5) years from the date of this
       Agreement, engage in any business which solicits any present or future
       employee of the Company or initiates discussions with any such employee
       regarding his or her termination or resignation from employment with the
       Company, so that such employee may accept employment with, or engagement
       as an employee, agent or consultant with Seller, directly or indirectly,
       as specified above; provided, however, that Seller shall not be
       prohibited by this Agreement from employing or soliciting the employment
       of any employee that the Company terminates after the date of such
       termination or with respect to whom the Company gives permission to
       Seller to employ or solicit employment.

It shall not be deemed a violation of this Section 11.1, if, pursuant to an
agreement with the Purchaser or the Company, agents of the Seller solicit
business on behalf of the Company or other affiliates of Purchaser after the
Closing Date.

                 11.2     Permitted Activities.  Seller shall have the right,
upon completion of the sale of the Shares to Purchaser, to continue to market
and sell its back-office, claims and other operational services and
applications involving technology solutions to dental organizations and
companies of all types, whether or not they compete with Purchaser or its
subsidiaries.  Additionally, nothing contained herein shall be construed to
limit, exclude or prohibit Seller from marketing life, health (other than
dental), annuity, vision or drug products to Purchaser's customers or providing
third party administration to self-insured accounts.  It is expressly
understood however that nothing contained in this Section 11.2 shall be deemed
in any way to limit, modify or release the obligation of Seller under Section
11.3 of this Agreement.

                 11.3     Non-Disclosure.  Seller covenants and agrees that all
information concerning the Company, including without limitation (i)
information regarding prices or premiums charged for products and services,
(ii) the assets, liabilities and financial condition of the Company and its
subsidiaries, (iii) the names and identities of customers and analyses of the
amount and types of products and services purchased by each such customer, (iv)
the dental health providers utilized by the Company and its subsidiaries and
the financial arrangements with such providers, and (v) the amount of
compensation to employees, constitute trade secrets and confidential,
proprietary business information which is the property of the Company and that,
unless otherwise required by law, from and after the date of this Agreement:

                 (a)      Seller shall use its best efforts and exercise utmost
       diligence to protect and safeguard all of such trade secrets and
       confidential, proprietary information;

                 (b)      Seller shall not, directly or indirectly, use, sell,
       license, publish, disclose or otherwise transfer or make available to
       others any of such trade secrets or confidential, proprietary
       information;





                                       32
<PAGE>   39
                 (c)      Without the prior written consent of the Company,
       Seller shall not, directly or indirectly, disclose any of such trade
       secrets or confidential, proprietary information; and

                 (d)      Seller shall not, directly or indirectly, use for its
       own benefit or for the benefit of another, any of such trade secrets or
       confidential, proprietary information.

It is expressly understood, however, that the foregoing shall not apply to any
information that was generally available to the public on a non-confidential
basis prior to the date of this Agreement or was or becomes generally available
to the public on a non-confidential basis from a third party who is not bound
to keep such information confidential.

         11.4    Nondisparagement.  For a period of three (3) years and after
the date of this Agreement, Seller further agrees that it shall not make or
publish any statement, written or oral, disparaging the reputation of the
Company or its subsidiaries, executive officers or any of its business services
or products or solicit or encourage any member of any prepaid dental plan of
the Company or its subsidiaries or any third party having a group agreement
with the Company or its subsidiaries to terminate the membership of such person
in the plan of the Company or its subsidiaries or to terminate such group
agreement.

         11.5    Reasonableness; Reformation.  Seller acknowledges and agrees
that (i) the provisions of this Article 11 are ancillary to the transaction
pursuant to which the Seller sold and the Purchaser acquired the Shares, (ii)
the provisions of this Agreement contain reasonable limitations as to time,
geographical area and scope of activities to be restrained and do not impose a
greater restraint than is necessary to protect goodwill and other business
interests of the Company and its subsidiaries, (iii) if any portion of the
covenants and agreements set forth in this Agreement are held to be invalid,
unreasonable, arbitrary or against public policy, then such portion of such
covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, and (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against public policy, a lesser time
period, scope of activities covered, and/or geographical area which is
determined to be reasonable, non-arbitrary and not against public policy may be
enforced against Seller.

         11.6    Remedies for Breach.  If Seller has failed to satisfactorily
cure any breach or threatened breach of any covenant or agreement contained
herein within ten (10) days after written notice of such breach or threatened
breach given by the Purchaser to Seller, any one or more of the following
remedies, as selected by the Purchaser in its sole discretion, shall be
available to the Purchaser in the event of a breach of this Agreement by Seller
hereunder:

                 (a)      Specific Performance.  In the event of a breach or
         threatened breach of any covenant or agreement of Seller in this
         Agreement, remedies at law will not adequately compensate the
         Purchaser for its injuries incurred as a result  thereof.
         Accordingly, injunctive and/or equitable relief shall be available to
         the Purchaser to





                                       33
<PAGE>   40
         specifically enforce this Agreement and prevent such breach and any
         continued breach of any covenant and agreement herein.  Seller agrees
         that a bond of no more than $10,000 in the aggregate will provide
         adequate protection to Seller and therefore no more than $10,000 in
         bond or other security shall be required to be posted by the Company
         by any court in any proceeding to obtain such injunctive or equitable
         relief.

                 (b)      Suit for Damages.  In addition to the remedies stated
         in Section 11.5(a) above, in the event of any breach of any covenant
         or agreement of Seller herein, Purchaser may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Seller under applicable law.


                                   ARTICLE 12
                              TERMINATION; WAIVER

         12.1    Termination.  This Agreement may be terminated, and the
transaction may be abandoned, at any time prior to the Closing,  as follows and
in no other manner:

                 (a)      Mutual Consent.  By the mutual consent of Purchaser
and the Seller;

                 (b)      By Purchaser or Seller: Condition Precedent.  By
Purchaser or Seller, upon written notice to the other, if the conditions to the
obligations of such canceling party or parties to consummate the transaction,
in the case of the Seller, as provided in Article 7 or, in the case of
Purchaser, as provided in Article 8, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this
Agreement unless the failure of the condition is the result of the material
breach of this Agreement by the party seeking to terminate; provided, however,
that, in the event all such conditions have been satisfied except solely the
condition with respect to obtaining all required consents, authorizations, and
approvals of governmental and regulatory agencies set forth in Sections 7.1(a)
and 8.1(a), respectively, and such failure is not due to a breach of this
Agreement by the non-terminating party, such date shall be automatically
extended for one thirty (30) day period provided, however, that in no event
shall such date be extended beyond an aggregate of one hundred fifty (150) days
after the date of this Agreement unless extended by the mutual agreement of the
Purchaser and the Seller;

                 (c)      By Purchaser or Seller: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Seller, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) one hundred fifty (150)
days after the date of this Agreement, unless such date is extended by mutual
agreement of Purchaser and Seller.





                                       34
<PAGE>   41
No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Seller,
Seller shall be entitled to retain the Earnest Money.  Any public announcement
of the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

         12.2    Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Seller, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser

however, that Purchaser shall not be relieved of any obligations as a result of
such assignment and that, in addition to Purchaser remaining liable, any such
assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  Seller shall be entitled to assign any of it

all of Seller's obligations under this Agreement. In connection with any such

this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part hereof with the remaining
provisions remaining in full force and effect and not affected by the illegal,
invalid or unenforceable provision or by severance herefrom.  Furthermore, in
lieu of such illegal, invalid or unenforceable provision there shall be added
automatically as part of this Agreement a provision similar in terms to such
illegal, invalid, or unenforceable provision as may be possible and still be
legal, valid and enforceable.

or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

                                   EXHIBIT A

                         EARNEST MONEY ESCROW AGREEMENT


         This Earnest Money Escrow Agreement (the "Agreement") is made as of
the 10th day of September, 1996 among UICI, a  Delaware corporation ("Seller");
United Dental Care, Inc., a Delaware corporation ("Purchaser"); and Texas
Commerce Bank National Association (the "Escrow Agent").

         WHEREAS, Seller and Purchaser have entered into that certain Stock
Purchase Agreement dated September 10, 1996 (the "Stock Purchase Agreement")
providing for the purchase of all the issued and outstanding shares of capital
stock of International Dental Plan, Inc., a Florida corporation ("IDP"), (IDP
being sometimes collectively referred to herein as the "Company") (collectively
the "Shares") from the Seller by Purchaser; and

         WHEREAS, in connection with the execution of the Stock Purchase
Agreement, Purchaser has agreed to place the sum of Two Hundred Thirty Thousand
and no/100ths Dollars ($230,000) in escrow and for the purposes hereinafter set
forth.  (Such escrow deposit and any interest earned thereon while such funds
are in escrow are referred to herein as the "Escrow Money"); and

         WHEREAS, the parties desire to effectuate the provisions of the Stock
Purchase Agreement with respect to the Escrow Money;

         NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the mutual terms
and conditions hereof, the parties hereby agree as follows:

         1.      Escrow Money.  Simultaneously with the execution of this
Agreement, Purchaser has deposited the sum of $230,000 in immediately available
funds with the Escrow Agent, the receipt of which is hereby acknowledged by the
Escrow Agent by its execution hereof.

         2.      Escrow Account.  The Escrow Money shall be held in escrow by
the Escrow Agent pursuant to the terms and conditions of this Agreement.  Upon
receipt of the Escrow Money,  the Escrow Agent shall place the Escrow Money
deposit into a non-interest bearing escrow account (the "Escrow Account") under
the following terms and conditions: (i) at the Escrow Agent; (ii) under the
name of Texas Commerce Bank National Association, as Escrow Agent and (iii)
under the federal tax identification (ID) number of the Purchaser
(#75-2309712).  All funds in the Escrow Account shall be invested by the Escrow
Agent in the Fidelity Institutional Cash Portfolio-Treasury Fund Number 695.
It is understood and agreed that the
<PAGE>   2
Escrow Agent will be issuing a 1099 INT statement to the Purchaser and the
Internal Revenue Service, even though the interest may be payable eventually to
either the Purchaser or the Seller as the case may be.  In the event the
interest is paid to the Purchaser, the Purchaser shall have the responsibility
as to any 1099 INT reporting thereof.  The Escrow Money shall at all times be
held the Escrow Account and shall only be delivered pursuant to the terms and
conditions of this Agreement.

         3.      Terms of Escrow.  The Escrow Money shall only be applied by
the Escrow Agent in accordance with the following terms and directions:

                 (a)      Application upon Closing.  In the event that the
         Seller has not furnished written notice to Purchaser and the Escrow
         Agent of the failure of Purchaser to consummate the Stock Purchase
         Agreement in accordance with Section 3(b) below prior to Closing under
         the Stock Purchase Agreement, then, upon the Closing, Escrow Agent
         shall receive a notice executed by Purchaser and Seller directing
         Escrow Agent to either (i) pay the Escrow Money to Seller as the
         notice shall direct in which case the Escrow Money shall constitute a
         credit against the Purchase Price or (ii) refund the Escrow Money to
         the Purchaser in which case it shall not constitute a credit against
         the Purchase Price.

                 (b)      Application upon Termination.  If Purchaser fails to
         consummate the Stock Purchase Agreement for any reason other than (i)
         a material breach of the Stock Purchase Agreement or this Agreement by
         Seller or (ii) the valid exercise of any right of termination by
         Purchaser expressly set forth in the Stock Purchase Agreement, then
         the Seller shall furnish written notice to Purchaser and the Escrow
         Agent of Purchaser's failure to consummate the Stock Purchase
         Agreement and directing that the Escrow Money be paid to the Seller.
         Ten (10) days after such notice is received by the Escrow Agent, the
         Seller shall be entitled to be paid the Escrow Money and the Escrow
         Agent shall release the Escrow Money to the Seller.  Otherwise, ten
         (10) days after receipt of written notice/demand from the Purchaser to
         the Escrow Agent (certifying that such notice/demand has been
         furnished to Seller) that one of the conditions stated in (i) or (ii)
         above has occurred and that the Purchaser is entitled to receive a
         refund of the Escrow Money, the Purchaser shall be entitled to be
         refunded the Escrow Money and the Escrow Agent shall release the
         Escrow Money to the Purchaser.

                 (c)      Automatic Termination.  In the event that the Escrow
         Agent has not received instructions as to the release of the Escrow
         Money before February 15, 1997, then this Escrow Agreement shall
         automatically terminate on February 15, 1997 and the Escrow Agent
         shall refund the Escrow Money to Purchaser without the necessity of
         any further notice or instructions of any kind.

                 (d)      Interest.  Interest earned on the Escrow Money shall
         be applied together with the Escrow Money and paid to the Seller or to
         Purchaser as the case may be as specified above.

         4.      Liability of Escrow Agent.  Purchaser and Seller hereby agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and amenities of the Escrow Agent:

                 (a)      The Escrow Agent is not a party to, and is not bound
         by, or charged with notice of, any agreement out of which this escrow
         may arise.

                 (b)      The Escrow Agent acts hereunder as a depository only,
         and is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or deposition the escrow or for any loss on any investment
         made pursuant to the provisions hereof.

                 (c)      The Escrow Agent shall be protected in acting upon
         any written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other paper or document which the
         Escrow Agent in good faith believes to be genuine and what it purports
         to be.

                 (d)      Purchaser and Seller, jointly and severally, agree to
         indemnify and hold the Escrow Agent harmless against any and all
         losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non- performance
         of its duties hereunder whether such losses, claims, demands,
         liabilities and expenses arise during or subsequent to performance of
         this Agreement, directly or indirectly, excluding, however, any such
         liability resulting from its gross negligence or willful misconduct.
         In the event the Escrow Agent becomes involved in litigation in
         connection with this escrow, Purchaser and Seller, jointly and
         severally, agree to indemnify and save the Escrow Agent harmless from
         any and all losses, claims, damages, liabilities and expenses,
         including attorney's fees and costs, interpleader costs and judgments,
         which may be incurred or suffered by Escrow Agent as a result thereof,
         excluding, however, any such liability resulting from its gross
         negligence or willful misconduct.  It is the express intent of the
         Purchaser and the Seller to indemnify and hold the Escrow Agent
         harmless against its own ordinary negligence.

                 (e)      In the event of any disagreement between any of the
         parties to this Agreement or with any third person resulting in
         adverse claims or demands being made in connection with the Escrow
         Money, or in the event the Escrow Agent in good faith is in doubt as
         to what action it should take hereunder, the Escrow Agent may, at its
         option, refuse to comply with any claims or demands on it, or refuse
         to take any other action hereunder, so long as such disagreement
         continues or doubt exists, and in such event, the Escrow Agent shall
         not be or become liable in any way or to any person for its failure or
         refusal to act, and the Escrow Agent shall be entitled to continue to
         so refrain from acting until (i) the rights of all the parties shall
         have been fully and finally adjudicated by a court of competent
         jurisdiction, or (ii) all differences shall have adjusted





                                      3
<PAGE>   4
         and all doubt resolved by agreement among all the interested parties 
         and the Escrow Agent shall have been notified thereof pursuant to
         written directions duly executed by all such persons.  In the event of
         conflicting demands on the Escrow Agent, the Escrow Agent may, at its
         option, deposit any and all funds in question with the court that
         would have jurisdiction over the matter, and in such event, the Escrow
         Agent is relieved of any further responsibility in connection with
         this escrow.

                 (f)      Escrow Agent may consult with its counsel or other
         counsel satisfactory to it concerning any question relating to its
         duties or responsibilities hereunder or otherwise in connection
         herewith, and shall not be liable for any action taken, suffered or
         omitted by it in good faith upon the advice of such counsel.

                 (g)      Escrow Agent may resign hereunder upon thirty (30)
         days' prior notice to the Seller and Purchaser.  Upon the effective
         date of such resignation, Escrow Agent shall deliver the Escrow Money
         to any substitute escrow agent designated by Seller and Purchaser in
         writing.  If Seller and Purchaser fail to designate a substitute
         escrow agent within thirty (30) days after the giving of such notice,
         Escrow Agent may institute a petition for the appointment of a
         successor escrow agent hereunder.  Escrow Agent's sole responsibility
         after such 30-day notice period expires shall be to hold the Escrow
         Money (without any obligation to reinvest the same) and to deliver the
         same to a designated substitute escrow agent, if any, or in accordance
         with the directions of a final order or judgment of a court of
         competent jurisdiction, at which time of delivery Escrow Agent's
         obligations hereunder shall cease and terminate.

         5.      Compensation of Escrow Agent.  As compensation for its
services hereunder, the Escrow Agent shall be entitled to the fees and expenses
set forth on Schedule 1 hereto.  All fees and expenses of the Escrow Agent
shall be paid equally by the Seller and the Purchaser.  In the event any of
such fees and expenses are not paid when due, the Escrow Agent may offset the
amount of such unpaid fees and expenses against amounts in the Escrow Account.

         6.      Non-Waiver.  Nothing contained in this Agreement shall be
deemed or construed to release or waive any of the rights or obligations of
Purchaser or Seller under the Stock Purchase Agreement, all rights and remedies
of Purchaser and Seller under this Agreement are cumulative of all other rights
which either of them may have under the Stock Purchase Agreement, by law or
otherwise.

         7.      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to

         8.      Entire Agreement.  This Agreement sets forth the entire
understanding of the parties and supersedes all prior agreements or
understandings, whether written or oral, with respect to the subject matter
hereof.  No terms, conditions or agreements other than those contained herein,
and no amendments or modifications hereto shall be valid unless made in writing
and signed by the parties hereto.

         9.      Capitalized Terms.  Capitalized terms in this Agreement which
are not otherwise defined herein shall have the same meanings as are provided

         11.     Termination.  This Agreement shall terminate at such time as
all of the Escrow Money shall have been released in accordance with the terms
and conditions of this Agreement; provided, however, that the terms and
provisions of Sections 4 and 5 shall survive the termination hereof.

         12.     Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or effect the meaning or construction of any of the
provisions of this Agreement.

         13.     Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  The parties shall have all remedies permitted to them by this
Agreement or law, and all such remedies shall be cumulative.

         14.     Attorney's Fees.  As between Seller and Purchaser only, in the
event any action or proceeding is commenced by Seller or Purchaser against the
other to (i) determine rights, duties or obligations hereunder, (ii) determine
a breach hereof and obtain damages therefor, or (iii) otherwise enforce this
Agreement, the prevailing party in such action or proceeding shall be entitled
to recover from the other party all costs and expenses thereof, including
reasonable attorney's fees and costs.

         15.     Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
Texas.

         16.     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                            STOCK PURCHASE AGREEMENT


         This Stock Purchase Agreement (this "Agreement") is made as of the
10th day of September, 1996 (the "Effective Date") by and among United Dental
Care, Inc., a Delaware corporation ("Purchaser") and UICI, United Management &
Consulting, Inc., an Oklahoma corporation, The United Management & Consulting,
Inc. Retirement Plan and The Marie C.  Montgomery Revocable Trust U/T/A dated
March 23, 1992 (collectively referred to herein as the "Sellers" and
individually as a "Seller").

         WHEREAS, the Sellers each own the respective number of shares of
Common Stock of United Dental Care, Inc., an Oklahoma corporation (the
"Company"), as set forth opposite the respective name of each Seller in Exhibit
A (all of such shares being collectively referred to herein as the "Shares");
and

         WHEREAS, the Shares represent approximately ninety percent (90%) of
the issued and outstanding shares of capital stock of the Company; and

         WHEREAS, subject to the terms and conditions hereinafter set forth,
the Sellers desire to sell to the Purchaser, and the Purchaser desires to
purchase from the Sellers, the Shares;

         NOW, THEREFORE, in consideration of the premises and the mutual terms
and conditions herein contained, the parties hereby agree as follows:


                                   ARTICLE 1
                            DEFINED TERMS/SCHEDULES

       1.1       Defined Terms.  As used in this Agreement, capitalized terms
shall have the meanings expressly set forth herein for such terms, and variants
and derivatives of such defined terms shall have correlative meanings.  To the
extent that certain of the defined terms set forth herein express agreements
between or among parties to this Agreement, the parties agree to the same by
execution of this Agreement.

       1.2       Schedules.  References to a Schedule shall include any
applicable disclosure expressly set forth on the face of any other Schedule
even if not specifically cross-referenced to such other Schedule.  It is
specifically acknowledged by the parties hereto that certain agreements and
documents listed on the Schedules are not to be delivered herewith, but were
previously or will be delivered or made available to Purchaser or its
representatives in connection with the due diligence investigation of the
Company conducted by Purchaser and its representatives prior to Closing.  All
such agreements and documents made available or delivered to Purchaser by the
Company and the Sellers shall be originals or true and correct copies of the
originals of all such agreements and documents.  Each Schedule shall be
considered a part hereof as if set forth herein in full; provided, however,
that the representations and warranties of Sellers set forth in this Agreement
shall not be affected or deemed modified,





                                       1

waived or limited in any respect by the information contained in any agreement
or document listed or referenced in the Schedules unless and only to the extent
that any qualification, modification, exception or limitation to any
representation and warranty of the Sellers is expressly set forth on the face
of a Schedule.


                                   ARTICLE 2
                               PURCHASE AND SALE

       2.1       Agreement to Sell and Purchase.  Subject to the terms and
conditions of this Agreement and in reliance on the representations, warranties
and covenants herein set forth, at the Closing the Sellers shall sell to
Purchaser, and Purchaser shall purchase from the Sellers, the Shares, free and
clear of any and all liens, claims, options, charges, pledges, security
interests, voting agreements or trusts, encumbrances or other restrictions or
interests of any kind or nature whatsoever (collectively, "Claims").

       2.2       Purchase Price.  Subject to the terms and conditions of this
Agreement and in reliance on the representations, warranties and covenants
herein set forth, the Purchaser shall pay to the Sellers as consideration for
the Shares, an aggregate purchase price (the "Purchase Price") equal to ninety
and 65/100s percent (90.65%) of the following:

                 (a)      Five Million Seven Hundred Fifty Thousand Dollars
($5,750,000) less an amount equal to 90.65% of the reserve to be created
pursuant to Section 11.9 hereof; and

                 (b)      plus or minus, as applicable, the Adjustment Amount
(as hereinafter defined in Section 2.3), if any, to be determined and paid in
accordance with Section 2.3 below.

At the Closing Purchaser shall pay to the Sellers the Purchase Price (less the
$200,000 amount to be retained in escrow pursuant to Section 2.3 below) by
certified or cashier's check (or by wire transfer of immediately available
funds to accounts of the Sellers in accordance with written directions provided
to Purchaser not less than two (2) business days prior to the Closing Date).

       2.3       Closing Financial Statements: Purchase Price Adjustment.

                 (a)      As soon as practicable following the calendar month
end immediately preceding the Closing Date but in no event later than ten (10)
days following such calendar month end, Sellers shall cause a statement setting
forth the consolidated adjusted net equity of the Company as of the end of the
month immediately preceding the Closing Date (the "Adjusted Net Equity
Statement") to be calculated and prepared in accordance with the principles and
procedures set forth on Exhibit B (the amount as thus determined shall
hereinafter be referred to as the "Adjusted Net Equity") and shall cause such
Adjusted Net Equity Statement to be delivered to the Purchaser not less than
three (3) business days prior to the Closing Date.  The "Adjustment Amount"
shall be either (i) the positive amount (if applicable) by which the Adjusted
Net Equity is greater than $750,000, or (ii) the negative amount (if
applicable) by which the Adjusted Net Equity is less than $750,000.  On the
basis of the Adjusted Net Equity





                                       2
<PAGE>   9
Statement subject, however, to the rights of the Purchaser as provided in
Section 2.3(b) and (c) below, Purchaser shall pay to the Sellers the Purchase
Price at the Closing which shall be allocated pro rata among the Stockholders
in accordance with their percentage ownership of the Shares; provided, however,
that the amount of Two Hundred Thousand Dollars ($200,000) shall be retained in
escrow pursuant to the Ernest Money Escrow Agreement (defined below until final
determination of the Adjustment Amount pursuant to Section 2.3(b) below).

                 (b)      Within thirty (30) business days after delivery of
the Adjusted Net Equity Statement by Sellers, Purchaser may deliver written
notice (the "Protest Notice") to Purchaser of any objections, and the basis
therefor, which the Purchaser may have to the Adjusted Net Equity Statement.
The failure of Purchaser to deliver such Protest Notice within the prescribed
time period will constitute the acceptance of the Adjusted Net Equity Statement
as delivered by Sellers to Purchaser.  During the ten (10) business days
following receipt of the Protest Notice by Sellers, Purchaser and Sellers shall
attempt to resolve any disagreement with respect to the Adjusted Net Equity
Statement and the appropriateness thereof.  If, at the end of the period
specified in the immediately preceding sentence, Purchaser and Sellers shall
have failed to resolve the disagreement specified in the Protest Notice, the
items in dispute shall be referred to Price Waterhouse L.L.P. or such other
accounting firm of national reputation as may be agreed to by the parties (the
"Arbitrator") for final determination within 45 days.  This provision for
arbitration shall be specifically enforceable by the parties and the
determination of the Arbitrator in accordance with the provisions hereof shall
be final and binding upon Purchaser and Seller with no right of appeal
therefrom.  The fees and expenses of the Arbitrator shall be paid by the party
whose last proposed offer for settlement of the items in dispute, taken as a
whole, was farther away from the final determination of the Arbitrator.

                 (c)      The Sellers, jointly and severally, and Purchaser

<PAGE>   30
by Purchaser, provided, however, that (i) such approval shall not be
unreasonably withheld and (ii) such review and approval shall not be required
of statements and announcements if prior review and approval would prevent the
timely and accurate dissemination of such statements and announcements as

Purchaser of any changes, additions, or events which may cause any change in or
addition to the Schedules delivered by them under this Agreement promptly after
the occurrence of the same and again at the Closing by delivery of appropriate
updates to all such Schedules.  No notification of a change or addition to a
Schedule made pursuant to this Section shall be deemed to cure any breach of
any representation or warranty resulting from such change or addition unless
Purchaser specifically agrees thereto in writing, nor shall any such
notification be considered to constitute or give rise to a waiver by Purchaser
of any condition set forth in this Agreement.  Nothing contained herein shall
be deemed to create or impose on Purchaser any duty to examine or investigate
any matter or thing for the purposes of verifying the representations and
warranties made by Sellers herein.  Purchaser shall not be deemed to have

has actual knowledge of such misrepresentation or breach of warranty and

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       11.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
the indemnification with respect to losses relating to Taxes shall expire six
(6) months after the termination of the applicable statute of limitations and
provided, further, however, that if, prior to the expiration of such two year
period, a state of facts shall have become known which threatens to give rise
to a liability against which any party hereto would be entitled to
indemnification hereunder and the indemnified party shall have given





                                       31
<PAGE>   38
notice of such facts to the indemnifying party, then the rights of the
indemnified party to indemnification with respect to such liability shall
continue until such liability shall have been finally determined and disposed
of (including and subject to disposition by the expiration of the applicable
statute of limitations with respect to such liability); and provided further,
however, that if a claim for indemnification is made pursuant to this Article
11, then such claim for indemnification or any claim arising out of the
wrongful failure to comply with the provisions of this Article 11 shall survive
until the expiration of the applicable period of limitations with respect to
such claim for indemnification; and provided further, however, that such two
year limitation specified above shall not apply to the extent provided
otherwise in Section 11.4(c) below.  With respect to the representations and
warranties of the parties, such representations and warranties shall be true as
of and at the date of the Closing but nothing contained herein shall be deemed
to require or imply that the accuracy of such representations and warranties
shall apply on a continuing basis as to facts existing after the date of the
Closing.  Except to the extent set forth herein, no investigation or
examination made by any party hereto shall constitute a waiver of any
representation or warranty and no representation or warranty shall be merged
into the Closing hereunder.  However, to the extent information is apparent on
the face of the Schedules or is otherwise expressly set forth herein, such
information shall be deemed to amend, limit and/or restate any representation
and warranties contained herein to the extent such information is inconsistent
with such representation or warranty.

       11.2      Indemnity.  Subject to the provisions of Section 11.4 below,

                 (a)      Sellers.  Each Seller, jointly and severally (except
as to the representations and warranties contained in Article 3 which shall be
several and not joint), agrees to indemnify and hold harmless the Company, its
Subsidiaries, and Purchaser, and their respective shareholders, partners,
directors, officers, employees and agents, from, against, and in respect of,
any loss, liability, claim, demand, or expense, including but not limited to
attorney, investigation and consultant fees and costs, and of any other kind
whatsoever arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers and the Company
       under this Agreement or under any other agreement or document delivered
       by the Sellers at Closing hereunder; and

                 (ii)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold each
Seller harmless from, against, and in respect of, any loss, liability, claim,
demand, or expense, including but not limited to attorney's fees and costs, of
any kind whatsoever, arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Sellers at Closing hereunder;





                                       32
<PAGE>   39
                 (ii)  Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Sellers are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 11.2(a) above; and

                 (iii)  Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       11.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
11.2(a) or 11.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might result in any such claim, demand or
action, such party shall promptly notify the other party or parties who would
be obligated to provide indemnity hereunder with respect to such claim, demand
or action, and such other party or parties shall have the right to take such
action as it or they may deem appropriate to resolve such matter.  The
indemnified party or parties shall have the right to employ  separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties, unless the employment of such counsel has been specifically authorized
by the indemnifying party or parties.  Any settlement of any action subject to
indemnity hereunder shall require the consent of the indemnified and the
indemnifying party which consent shall not be unreasonably withheld and shall
be given within five (5) days following the giving of notice thereof.  The
indemnifying party or parties shall not be liable for any settlement of any
action effected without its or their consent, but if settled with the consent
of the indemnifying party or parties or if there be a final judgment for the
plaintiff in any such action, the indemnifying party or parties shall indemnify
and hold harmless the indemnified party from and against any loss or liability
by reason of such settlement or judgment.  If requested by the indemnifying
party, the indemnified party shall cooperate with the indemnifying party and
its counsel and use its best efforts in contesting any such claim or, if
appropriate, in making any counter-claim or cross-complaint against the party
asserting the claim, provided that the indemnifying party will reimburse the
indemnified party for reasonable expenses incurred in so cooperating upon
presentation of receipts or other evidence of such expense.  The indemnifying
party and its representatives shall have full and complete access during
reasonable hours to all books, records and files of the indemnified party
expressly related to the defense of any claim for indemnification undertaken by
the indemnifying party pursuant to this Article 11, or for any other purpose in
connection therewith; provided that the indemnifying party shall safeguard and
maintain the confidentiality of all such books, records and files.

       11.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Sellers nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Twenty-Five
Thousand Dollars ($25,000.00) (the "Threshold"),





                                       33
<PAGE>   40
which excess amount shall be recoverable in accordance with the terms hereof;
provided, however, that the $25,000 limitation set forth in this Section
11.4(a) shall not apply to the matters described in Section 11.4(c).

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 11.1 and this Section 11.4(b) shall not apply
to the matters described otherwise in Section 11.1 and Section 11.4(c) as to
which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party shall have given notice of such facts to the indemnifying
party and made a claim for indemnification within such two-year period, then
the right to indemnification with respect thereto shall remain in effect until
such matter shall have been finally determined and disposed of and any
indemnification due in respect thereof shall have been paid.

                 (c)      Certain Matters.         The following are the
matters referred to in Section 11.4(a) and Section 11.4(b):

                 (i)      Losses arising from fraud or an intentional
       misrepresentation on the part of any Seller; and

                 (ii)     Losses arising from the intentional breach of any
       covenant or agreement by a Seller contained in this Agreement.

       11.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Sellers and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       11.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.  In
the event that the Purchaser shall elect to pay or cause the Company to pay any
severance benefits to employees of the Company who may be terminated at or
after





                                       34
<PAGE>   41
the Closing, it is expressly understood that the Sellers shall not be entitled
to receive such severance benefits.

       11.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 4.21 with the appropriate governmental  or regulatory
agencies within five (5) business days of the Effective Date.

       11.8      Annuity Contracts.  UDC Life has issued annuity policy
contracts UDC000003, UDC000004 and UDC000005 to Ronald L. and Gladys Jensen
(the "Jensens") representing the annuity reserves in UDC Life.  Purchaser
agrees to place the annuity account values for these annuity policies (at June
30, 1996 in the amount of $388,308.56) in a custodial trust account with
American Bank & Trust, 3001 E. Memorial Road, Edmond, Oklahoma 73013, and
provide an annual custodial trust account statement to the Jensens as of the
end of each respective calendar year as long as such annuity policy contracts
remain with UDC Life.  Prior to Closing, UDC Life intends to sell additional
annuity policy contracts and receive an additional $150,000 in annuity
reserves.  Such annuity account value reserves shall also be included in such
custodial trust account.  In the event UDC Life is liquidated, terminated or
purchased by another entity subsequent to the execution of this Agreement and
the annuity policy contracts remain in force, then Purchaser agrees to cause
UDC Life to reinsure the annuity policy contracts by assumption reinsurance to
The MEGA Life and Health Insurance Company or such other life insurance company
as the Jensens may direct.  If the annuity policy contracts expire, terminate
or are surrendered prior to UDC Life's liquidation, termination or purchase by
another entity, then the terms of this Section 11.8 governing the annuity
policy contracts shall terminate.  Purchaser agrees that it shall follow the
investment directions of the Mega Life and Health Insurance Company with
respect to the investment of such trust funds.

       11.9      Tax Reserve.  Purchaser and Sellers agree that at the Closing
the Company shall establish a reserve on its books for potential tax
liabilities arising out of periods prior to the Closing Date.  Such tax reserve
shall be in the approximate amount of $150,000 with the precise amount thereof
to be determined by Purchaser and Sellers at or prior to the Closing Date.  The
precise amount of such reserve shall be deducted from the Purchase Price as
specified in Section 2.2(a) hereof.  The Company shall further credit such
reserve with interest at an interest rate equal to the interest rate paid on
eighteen (18) month United States Treasury Bills from and after the Closing
Date.  Such reserve shall be maintained until the final tax year for the
periods to which such reserve relates is closed (approximately September 15,
1999).  The funds in such tax reserve may be used to pay any such tax
liabilities with the consent of the Sellers and any funds remaining in such
reserve when the final tax year is closed, if any, shall be distributed to the
Sellers and the Minority Stockholders on a prorata basis based on their share
ownership on the Closing Date.  Notwithstanding any provision hereof to the
contrary, nothing contained in this Section 11.9 shall be deemed to limit or
restrict any obligation of the Sellers to indemnify the Purchaser or the
Company with respect to such matters except, solely, to the extent funds are
actually used from such reserve to pay any such tax liabilities.

                                NON-COMPETITION

       12.1      Covenant Not to Compete; Non-Solicitation.  For and in
consideration of the purchase by the Purchaser of the Shares pursuant to this
Agreement, and the payments payable by the Purchaser pursuant to this
Agreement, each Seller covenants and agrees that it shall not, directly or
indirectly, through its officers, employees, agents or representatives as an
employer, consultant, creditor, investor, owner, agent, principal, partner,
shareholder, or through any other kind of ownership (other than ownership of
securities of any publicly held entity in which the Seller, directly or
indirectly, in the aggregate beneficially owns less than two percent (2%) of
any class of outstanding securities), or in any other representative or
individual capacity, do any of the following:

                 (i)      for a period of three (3) years from the date of this
       Agreement, engage in (i) the operation of a dental health indemnity
       insurance company, (ii) the operation of prepaid dental plans and dental
       preferred provider organizations, and (iii) the provision of management,
       administrative and related services to dental health indemnity insurance
       carriers, dental preferred provider organizations, and prepaid dental
       plans (collectively the "Dental Services Business") in the continental
       United States (the "Restricted Area");

                 (ii)     for a period of three (3) years from the date of this
       Agreement, engage in any business which calls upon, solicits, diverts or
       takes away any customer or customers of the Company in the Restricted
       Area for the purpose of selling or attempting to sell to any of said
       customers any products or services similar to any products or services
       heretofore sold or provided to any of such customers by the Company; and

                 (iii)    for a period of five (5) years from the date of this
       Agreement, engage in any business which solicits any present or future
       employee of the Company or initiates discussions with any such employee
       regarding his or her termination or resignation from employment with the
       Company, so that such employee may accept employment with, or engagement
       as a partner, investor, shareholder, employee, agent or consultant with
       Seller, directly or indirectly, as specified above; provided, however,
       that Seller shall not be prohibited by this Agreement from employing or
       soliciting the employment of any employee that the Company terminates
       after the date of such termination.

                 12.2     Permitted Activities.  UICI shall have the right,
upon completion of the sale of the Company to Purchaser, to continue to market
and sell its back-office, claims and other operational applications involving
technological solutions to dental organizations and companies of all types,
whether or not in competition with Purchaser.  Additionally, nothing contained
herein shall be construed to limit, exclude or prohibit UICI from marketing
life, health (other than dental), annuity vision or drug products to
Purchaser's customers or providing third party administration to self-insured
accounts.

                 12.3     Non-Disclosure.  Each Seller covenants and agrees
that all information concerning the Company, including without limitation (i)
information regarding prices or





                                       36
<PAGE>   43
premiums charged for products and services, (ii) the assets, liabilities and
financial condition of the Company and its subsidiaries, (iii) the names and
identities of customers and analyses of the amount and types of products and
services purchased by each such customer, (iv) the dental health providers
utilized by the Company and its subsidiaries and the financial arrangements
with such providers, and (v) the amount of compensation to employees,
constitute trade secrets and confidential, proprietary business information
which is the property of the Company and that, unless otherwise required by
law, from and after the date of this Agreement:

                 (a)      Each Seller shall use its best efforts and exercise
       utmost diligence to protect and safeguard all of such trade secrets and
       confidential, proprietary information;

                 (b)      Each Seller shall not, directly or indirectly, use,
       sell, license, publish, disclose or otherwise transfer or make available
       to others any of such trade secrets or confidential, proprietary
       information;

                 (c)      Without the prior written consent of the Company,
       each Seller shall not, directly or indirectly, disclose any of such
       trade secrets or confidential, proprietary information; and

                 (d)      Each Seller shall not, directly or indirectly, use
       for his own benefit or for the benefit of another, any of such trade
       secrets or confidential, proprietary information.

It is expressly understood, however, that the foregoing shall not apply to any
information that was generally available to the public on a non-confidential
basis prior to the date of this Agreement or was or becomes generally available
to the public on a non-confidential basis from a third party who is not bound
to keep such information confidential.

         12.4    Nondisparagement.  For a period of three (3) years and after
the date of this Agreement, each Seller further agrees that it shall not make
or publish any statement, written or oral, disparaging the reputation of the
Company or its subsidiaries, executive officers or any of its business services
or products or solicit or encourage any member of any prepaid dental plan of
the Company or its subsidiaries or any third party having a group agreement
with the Company or its subsidiaries to terminate the membership of such person
in the plan of the Company or its subsidiaries or to terminate such group
agreement.

         12.5    Reasonableness; Reformation.  Each Seller acknowledges and
agrees that (i) the provisions of this Article 12 are ancillary to the
transaction pursuant to which the Seller sold and the Purchaser acquired the
Shares, (ii) the provisions of this Agreement contain reasonable limitations as
to time, geographical area and scope of activities to be restrained and do not
impose a greater restraint than is necessary to protect goodwill and other
business interests of the Company and its subsidiaries, (iii) if any portion of
the covenants and agreements set forth in this Agreement are held to be
invalid, unreasonable, arbitrary or against public policy, then such portion of
such covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, and (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable





                                       37
<PAGE>   44
to any provision of this Agreement to be invalid, unreasonable, arbitrary or
against public policy, a lesser time period, scope of activities covered,
and/or geographical area which is determined to be reasonable, non-arbitrary
and not against public policy may be enforced against each Seller.

         12.6    Remedies for Breach.  If a Seller has failed to satisfactorily
cure any breach or threatened breach of any covenant or agreement contained
herein within ten (10) days after written notice of such breach or threatened
breach given by the Purchaser to each Seller, any one or more of the following
remedies, as selected by the Purchaser in its sole discretion, shall be
available to the Purchaser in the event of a breach of this Agreement by the
Seller hereunder:

                 (a)      Specific Performance.  In the event of a breach or
         threatened breach of any covenant or agreement of a Seller in this
         Agreement, remedies at law will not adequately compensate the
         Purchaser for its injuries incurred as a result  thereof.
         Accordingly, injunctive and/or equitable relief shall be available to
         the Purchaser to specifically enforce this Agreement and prevent such
         breach and any continued breach of any covenant and agreement herein.
         Such Seller agrees that a bond of no more than $10,000 in the
         aggregate will provide adequate protection to such Seller and
         therefore no more than $10,000 in bond or other security shall be
         required to be posted by the Company by any court in any proceeding to
         obtain such injunctive or equitable relief.

                 (b)      Suit for Damages.  In addition to the remedies stated
         in Section 12.5(a) above, in the event of any breach of any covenant
         or agreement of a Seller herein, Purchaser may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Seller under applicable law.


                                   ARTICLE 13
                              TERMINATION; WAIVER

         13.1    Termination.  This Agreement may be terminated, and the
transaction may be abandoned, at any time prior to the Closing,  as follows and
in no other manner:

                 (a)      Mutual Consent.  By the mutual consent of Purchaser
and the Sellers;

                 (b)      By Purchaser or Sellers: Condition Precedent.  By
Purchaser or Sellers, upon written notice to the other, if the conditions to
the obligations of such canceling party or parties to consummate the
transaction, in the case of the Sellers, as provided in Article 8 or, in the
case of Purchaser, as provided in Article 9, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this

Sellers shall be entitled to retain the Earnest Money.  Any public announcement

understanding of the parties and supersede all





                                       42
<PAGE>   49
prior agreements or understandings, whether written or oral, with respect to
the subject matter hereof.  This Agreement may be amended, modified or
supplemented only by a written agreement executed by Purchaser and Sellers.

         15.4    Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any affiliate of
Purchaser without the necessity of seeking the consent of the Sellers;
provided, however, that Purchaser shall not be relieved of any obligations as a
result of such assignment and that, in addition to Purchaser remaining liable,
any such assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  None of the Sellers shall be entitled to
assign any of their respective rights or obligations under this Agreement;
provided, however, that the rights and obligations of a Seller may be assigned
by operation of law or may be assigned to an individual retirement account,
pension plan, trust or other entity under the control of such Seller but any
such assignment shall not relieve or release such Seller of any obligations
hereunder as a result of such assignment and that, in addition to such Seller
remaining liable, any such assignee shall assume and become liable for any and
all of such Seller's obligations under this Agreement. In connection with any
such assignment, a Seller may transfer all or any portion of the Shares owned
by the Seller and thereby effect an assignment on the basis specified above.

         15.5    Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

         15.7    Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

         15.8    Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

         15.9    Attorney's Fees and Costs.  In the event of a breach by any
party to this Agreement and commencement of a subsequent legal action in a
court of law or forum of arbitration, or in the event legal counsel is
consulted in the event of any such breach or in anticipation of any such
prospective legal action, the prevailing party in any such dispute shall be
entitled to reimbursement of reasonable attorney's fees and court costs,
including, but not limited to, the costs of expert witnesses, transportation,
lodging and meal costs of the parties and witnesses, costs of transcript
preparation and other reasonable and necessary direct and incidental costs of
such dispute.  "Prevailing party" is the party in whose favor final judgment is
rendered.

         15.10   Time.  Time is of the essence under this Agreement.

         15.11   Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
Texas.

         15.12   Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                              EMPLOYMENT AGREEMENT


         This Employment Agreement (this "Agreement") is made as of __________,
1996 (the "Effective Date"), by and between United Dental Care, Inc., an
Oklahoma corporation acting by and through its hereunto duly authorized officer
(the "Company"), and Don Germany (the "Executive").

         WHEREAS, THE Company desires to employ the Executive and the Executive
is willing to render his services to the Company on the terms and conditions
with respect to such employment hereinafter set forth;

         NOW, THEREFORE, in consideration of premises and the mutual terms and
conditions hereof, the Company and the Executive hereby agree as follows:

         1. Employment. The Company hereby employs the Executive and the
Executive hereby accepts employment with the Company upon the terms and
conditions hereinafter set forth.

         2. Exclusive Services. The Executive shall devote his full working
time, ability and attention exclusively to the business of the Company during
the term of this Agreement and shall not, directly or indirectly, render any
services of a business, commercial or professional nature to any other person,
corporation or organization whether for compensation or otherwise, without the
prior knowledge and consent of the Board of Directors of the Company.

            Executive has disclosed to the Company that (a) the Executive has an
ownership interest in DRG Reinsurance LTD and United Insurance Agency; (b) that
the Executive receives commissions from Courtsey Insurance Agency and American
Insurance Agency, and (c) the Executive serves on the Board of Directors of the
Retail Merchants Association of Oklahoma City, Oklahoma. The Executive has
represented to the Company that such activities do not constitute any conflict
of interest with his responsibilities under this Agreement and do not involve a
significant amount of time that would interfere with his ability to perform his
duties under this Agreement. Based on such representations, the Company has
consented to such activities.

         3. Duties. The Executive is hereby employed by the Company and shall
render his services at the principal business offices of the Company located in
the State of Oklahoma, as such may be located from time to time, unless
otherwise agreed between the Board of Directors of the Company (the "Board")
and the Executive. The Executive shall have such authority and



                                       1

shall perform such duties as are specified by the President of the Company;
subject, however, to such limitations, instructions, directions, and control as
the Board may specify from time to time in its sole discretion.

         4. Term. This Agreement shall have a term of four (4) years commencing
as of the Effective Date, subject to earlier termination as hereinafter
provided.

         5. Compensation. As compensation for his services rendered under this
Agreement, the Executive shall be entitled to receive the following:

                  (a) Base Salary. The Executive shall initially be paid a base
         annual salary of Seventy-Seven Thousand and No/100 Dollars
         ($77,000.00) per year, payable in installments on the regular payroll
         dates of each month for the Company during the term of this Agreement,
         prorated for any partial employment month. Such basic annual salary
         shall be subject to increase from time to time as authorized by the
         Board in its sole discretion.

                  (b) Bonuses. In addition to his base annual salary, the
         Executive shall be entitled to receive a bonus in an amount equal to
         $1.00 for each enrollment application of a subscriber (irrespective of
         whether or not any dependents are covered by such application) which
         application is accepted by the Company. Additionally, the Executive
         shall be entitled to an incentive bonus of not less than $5,000 per
         year based on whether the Company meets or exceeds its annual budget
         for such year. The specific terms and conditions of such incentive
         bonus for each year during the term of this Agreement shall be
         mutually established by the Company and the Executive.

                  (c) Additional Compensation. The Executive shall be paid such
         additional compensation and bonuses, if any, as may be determined in
         the sole discretion of the Board.

         6. Benefits. In addition to the compensation to be paid to the
Executive pursuant to Paragraph 5 hereof, the Executive shall further be
included in any hospital, surgical, and medical benefit plan, any group term
life insurance policy, any pension or profit sharing plan, and all other
benefits which may be extended from time to time to employees of the Company
generally by the Board in its sole discretion.

         7. Reimbursement of Expenses. Subject to such rules and procedures as
from time to time are specified by the Company acting by and through the
President of the Company and/or the Board, the Company shall reimburse the
Executive on a monthly basis for reasonable business expenses necessarily
incurred in the performance of his duties under this Agreement.

         8. Confidentiality/Trade Secrets. The Executive acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary 



                                       2
<PAGE>   56



business information of the Company. Both during the term of this Agreement and
thereafter, the Executive covenants and agrees as follows:

                  (a) that he shall use his best efforts and exercise utmost
         diligence to protect and safeguard the trade secrets and confidential
         and proprietary information of the Company including but not limited
         to the identity of its customers and suppliers, its arrangements with
         customers and suppliers, and its technical data, records, compilations
         of information, processes, and specifications relating to its
         customers, suppliers, products and services;

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         9. Intellectual Property. The Executive covenants and agrees that he
will fully inform and disclose to the Company all inventions, designs,
improvements, discoveries and processes ("Inventions") which he has now or may
hereafter have during his employment with the Company and which pertain or
relate to the business of the Company or to any experimental work, products,
services or processes of the Company in progress or planned for the future,
whether conceived by the Executive alone or with others and whether or not
conceived during regular working hours. All such Inventions shall be the
exclusive property of the Company. The Executive shall assist the Company, at
any time during or after his employment, in perfecting its rights in all
Inventions and shall execute all documents and do all things necessary to vest
the Company with full and exclusive title thereto and to protect the same
against infringement by others. If such assistance takes place after his
employment is terminated the Executive shall be paid by the Company at a
reasonable rate for any time actually spent in rendering such assistance at the
request of the Company.

         10. Non-Competition. (a) The Executive covenants and agrees that,
during the period of his employment, he shall not, without the prior written
consent of the Board, directly or indirectly, as an employee, employer,
consultant, agent, principal, partner, shareholder, corporate officer,
director, or through any other kind of ownership (other than ownership of
securities of publicly held corporations of which the Executive owns less than
two percent (2%) of any class of outstanding securities) or in any other
representative or individual capacity, engage in any business or render any
services to any business that is in competition in any manner whatsoever with
the business of the Company.

         (b) In addition, after termination of this Agreement, the Executive
covenants and agrees that, for the period that the Company is continuing to
make severance payments pursuant to Section 12(c) below, if applicable, he
shall not directly or indirectly, as an employee, employer, consultant,
creditor, investor, owner, agent, principal, partner, shareholder, corporate
officer, director or through any other kind of ownership (other than ownership

indirectly, in the aggregate owns less than two percent (2%) of any class of
outstanding securities), or in any other representative or individual capacity,
do any of the following:

                           (i) engage in the dental services business in the
                  States of Oklahoma, Kansas, Missouri, Arkansas and Texas (the
                  "Restricted Area") that is in competition in any manner
                  whatsoever with the Dental Services Business conducted by the
                  Company, including, without limitation, the business of a
                  dental health indemnity insurance company, a prepaid dental
                  plan, a dental preferred provider organization, a dental

                  Restricted Area;

                           (ii) engage in any business which calls upon,
                  solicits, diverts or takes away any customer or customers of
                  the Company in the Restricted Area for the purpose of selling
                  or attempting to sell to any of said customers any products
                  or services similar to any products or services heretofore
                  sold or provided to any of such customers by the Company;

                           (iii) engage in any business which solicits any

                  termination or resignation from employment with the Company,
                  so that such employee may accept employment with, or
                  engagement as a partner, investor, shareholder, employee,
                  agent or consultant with Executive, directly or indirectly,
                  as specified above; provided, however, that Executive shall
                  not be prohibited by this Agreement from employing or
                  soliciting the employment of any employee that the Company
                  terminates after the date of such termination; and

                           (iv) make or publish any statement, written or oral,
                  disparaging the reputation of the Company or its

                  services or products or solicit or encourage any member of
                  any prepaid dental plan of the Company or its subsidiaries or

                  its subsidiaries to terminate the membership of such person
                  in the plan of the Company or its subsidiaries or to
                  terminate such group agreement.

                  (d) In its sole discretion, the Company shall have the right
         at any time and from time to time, evidenced solely by the written
         approval of the Board of Directors of the Company, to waive all or any
         portion of the rights of the Company under the 



                                       4
<PAGE>   58



         covenants not to compete contained in this Agreement as applicable to
         Executive, including, without limitation, reducing the scope of
         covenant not to compete applicable to Executive or reducing the time
         period or the geographical area of the covenant not to compete
         applicable to Executive; provided that as so amended by waiver such
         covenant not to compete shall remain fully in effect. In order to be
         effective, any such waiver must be in writing, approved by the Board
         of Directors of the Company as provided above, and executed by an
         authorized officer of the Company.

                  (e) Executive acknowledges and agrees that the provisions of
         this Agreement contain reasonable limitations as to time, geographical
         area and scope of activities to be restrained and do not impose a
         greater restraint than is necessary to protect goodwill and
         other business interests of the Company and its subsidiaries, (iii) if
         any portion of the covenants and agreements set forth in this
         Agreement are held to be invalid, unreasonable, arbitrary or against
         public policy, then such portion of such covenants shall be considered
         divisible as to time, scope of activities covered, and geographical
         area, (iv) if any court of competent jurisdiction determines the
         specified time period, scope of activities covered, or the specified
         geographical area applicable to any provision of this Agreement to be
         invalid, unreasonable, arbitrary or against public policy, a lesser
         time period, scope of activities covered, and/or geographical area
         which is determined to be reasonable, non-arbitrary and not against
         public policy may be enforced against Executive.

         11. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8, 9 and 10 of this Agreement shall continue to be
binding upon the Executive, notwithstanding the termination of his employment
with the Company for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement and any other agreement between the Company and the Executive. The
existence of any claim or cause of action by the Executive against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of any or all of such covenants. It
is expressly agreed that the remedy at law for the breach of any such covenant
is inadequate and the injunctive relief shall be available to prevent to the
breach or any threatened breach thereof.

         12. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         thirty (30) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon thirty (30) days prior written notice to the Executive.



                                       5
<PAGE>   59


                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:

                           (1) If the Executive becomes disabled for a period
                  of more than forty-eight (48) consecutive days;

                           (2) If the Executive for reasons other than illness
                  or injury absents himself from his duties without the consent
                  of the Board for more than ten (10) consecutive days;

                           (3) If the Executive should die (effective on the
                  date of death);

                           (4) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (5) If the Executive should willfully breach or
                  habitually neglect his duties which he is required to perform
                  under this Agreement or otherwise fail to comply with the
                  terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in
                  Paragraphs 8, 9 and 10 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by his prior to the date of termination as provided herein
computed on a pro rata basis to and including such date of termination. In the
event the Company terminates this Agreement without cause pursuant to Paragraph
12(b) above, the Executive shall be entitled to receive a severance payment as
liquidated damages for, and in lieu of, any and all damages which he may incur
as a result of such termination in an amount equal to his basic salary as
specified in Paragraph 5(a) as then in effect on the date of termination equal
to such salary which otherwise would have been payable over the remaining term
of this Agreement. Such severance payment shall be payable in installments on
the same dates that such payments would have been made during the term of this
Agreement. The Executive shall be entitled to no further compensation as of the
date of termination of this Agreement specifically including but not limited to
any unearned bonuses under this Agreement. Any termination of this Agreement
shall be without prejudice to any right or remedy to which the terminating
party may be entitled either at law, in equity, or under this Agreement.

         13. Notices. Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to

         held to be illegal, invalid, or unenforceable under present or future
         laws effective during the term hereof, such provision shall be fully
         severable and this Agreement shall be construed and enforced as if

         Agreement.

                  (f) Titles. Titles of the paragraphs herein are used solely

                  (e) Executive acknowledges and agrees that the provisions of
         this Agreement contain reasonable limitations as to time, geographical
         area and scope of activities to be restrained and do not impose a
         greater restraint than is necessary to protect goodwill and other
         business interests of the Company and its subsidiaries, (iii) if any
         portion of the covenants and agreements set forth in this Agreement
         are held to be invalid, unreasonable, arbitrary or against public
         policy, then such portion of such covenants shall be considered
         divisible as to time, scope of activities covered, and geographical
         area, (iv) if any court of competent jurisdiction determines the
         specified time period, scope of activities covered, or the specified
         geographical area applicable to any provision of this Agreement to be
         invalid, unreasonable, arbitrary or against public policy, a lesser
         time period, scope of activities covered, and/or geographical area
         which is determined to be reasonable, non-arbitrary and not against
         public policy may be enforced against Executive.

         11. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8, 9 and 10 of this Agreement shall continue to be
binding upon the Executive, notwithstanding the termination of her employment
with the Company for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement and any other agreement between the Company and the Executive. The
existence of any claim or cause of action by the Executive against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of any or all of such covenants. It
is expressly agreed that the remedy at law for the breach of any such covenant
is inadequate and the injunctive relief shall be available to prevent to the
breach or any threatened breach thereof.

         12. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         her employment at any time during the term of this Agreement by giving
         thirty (30) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon thirty (30) days prior written notice to the Executive.

                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:

                           (1) If the Executive becomes disabled for a period
                  of more than forty-eight (48) consecutive days;

                           (2) If the Executive for reasons other than illness
                  or injury absents herself from her duties without the consent
                  of the Board for more than ten (10) consecutive days;

                           (3) If the Executive should die (effective on the
                  date of death);

                           (4) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (5) If the Executive should willfully breach or
                  habitually neglect her duties which she is required to
                  perform under this Agreement or otherwise fail to comply with
                  the terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in
                  Paragraphs 8, 9 and 10 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by her prior to the date of termination as provided herein
computed on a pro rata basis to and including such date of termination. In the
event the Company terminates this Agreement without cause pursuant to Paragraph
12(b) above, the Executive shall be entitled to receive a severance payment as
liquidated damages for, and in lieu of, any and all damages which she may incur
as a result of such termination in an amount equal to her basic salary as

to such salary which otherwise would have been payable over the remaining term
of this Agreement. Such severance payment shall be payable in installments on
the same dates that such payments would have been made during the term of this
Agreement. The Executive shall be entitled to no further compensation as of the
date of termination of this Agreement specifically including but not limited to

transmission if made within customary business hours, or if not transmitted

                         EARNEST MONEY ESCROW AGREEMENT


        This Earnest Money Escrow Agreement (the "Agreement") is made as of the
10th day of September, 1996 among UICI, a Delaware corporation, United
Management & Consulting, Inc., an Oklahoma corporation, United Management &
Consulting, Inc. Retirement Plan and Marie C. Montgomery Revocable Trust U/T/A
March 23, 1992 referred to herein collectively as the "Sellers" and
individually as a "Seller"); United Dental Care, Inc., a Delaware corporation
("Purchaser"); and Texas Commerce Bank National Association (the "Escrow
Agent").

        WHEREAS, Sellers and Purchaser have entered into that certain Stock
Purchase Agreement dated September 10, 1996 (the "Stock Purchase Agreement")
providing for the purchase of ninety and 65/100ths percent (90.65%) the issued
and outstanding shares of capital stock of United Dental Care, Inc., an
Oklahoma corporation (the "Company"), (collectively the "Shares") from the
Sellers by Purchaser; and

        WHEREAS, in connection with the execution of the Stock Purchase
Agreement, Purchaser has agreed to place the sum of Two Hundred Forty Thousand
and no/100ths Dollars ($240,000) in escrow for the purposes hereinafter set
forth.  (Such escrow deposit and any interest earned thereon while such funds
are in escrow are referred to herein as the "Escrow Money"); and

        WHEREAS, the parties desire to effectuate the provisions of the Stock
Purchase Agreement with respect to the Escrow Money;

        NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the mutual terms
and conditions hereof, the parties hereby agree as follows:

        1.       Escrow Money.  Simultaneously with the execution of this
Agreement, Purchaser has deposited the sum of $240,000 in immediately available
funds with the Escrow Agent, the receipt of which is hereby acknowledged by the
Escrow Agent by its execution hereof.

        2.       Escrow Account.  The Escrow Money shall be held in escrow by
the Escrow Agent pursuant to the terms and conditions of this Agreement.  Upon
receipt of the Escrow Money,  the Escrow Agent shall place the Escrow Money
deposit into a non-interest bearing escrow account (the "Escrow Account") under
the following terms and conditions: (i) at the Escrow Agent; (ii) under the
name of Texas Commerce Bank National Association as Escrow Agent and (iii)
under the federal tax identification (ID) number of the Purchaser
(#75-2309712).




                                      1
<PAGE>   2
All funds in the Escrow Account shall be invested by the Escrow Agent in the
Fidelity Institutional Cash Portfolio-Treasury Fund Number 695.  It is
understood and agreed that the Escrow Agent will be issuing a 1099 INT
statement to the Purchaser and the Internal Revenue Service, even though the
interest may be payable eventually to either the Purchaser or the Sellers as
the case may be.  In the event the interest is paid to the Purchaser, the
Purchaser shall have the responsibility as to any 1099 INT reporting thereof.
The Escrow Money shall at all times be held in the Escrow Account and shall
only be delivered pursuant to the terms and conditions of this Agreement.

        3.       Terms of Escrow.  The Escrow Money shall only be applied by
the Escrow Agent in accordance with the following terms and directions:

                 (a)     Application upon Closing.  In the event that the
        Sellers have not furnished written notice to Purchaser and the Escrow
        Agent of the failure of Purchaser to consummate the Stock Purchase
        Agreement in accordance with Section 3(b) below prior to Closing under
        the Stock Purchase Agreement, then, upon the Closing, Escrow Agent
        shall receive a notice executed by Purchaser and Sellers directing
        Escrow Agent to either (i) pay the Escrow Money to Sellers as the
        notice shall direct in which case the Escrow Money shall constitute a
        credit against the Purchase Price or (ii) refund the Escrow Money to
        the Purchaser in which case it shall not constitute a credit against
        the Purchase Price; provided, however, that the Escrow Agent shall
        retain the sum of $200,000 to be held until final determination of the
        Adjustment Amount pursuant to Section 2.3 of the Stock Purchase
        Agreement.  Such $200,000 balance of the Escrow Money and any interest
        earned thereon shall be paid in accordance with a notice given by
        Purchaser and Sellers after such final determination.

                 (b)     Application upon Termination.  If Purchaser fails to
        consummate the Stock Purchase Agreement for any reason other than (i) a
        material breach of the Stock Purchase Agreement or this Agreement by
        Sellers or (ii) the valid exercise of any right of termination by
        Purchaser expressly set forth in the Stock Purchase Agreement, then the
        Sellers shall furnish written notice to Purchaser and the Escrow Agent
        of Purchaser's failure to consummate the Stock Purchase Agreement and
        directing that the Escrow Money be paid to the Sellers.  Ten (10) days
        after such notice is received by the Escrow Agent, the Sellers shall be
        entitled to be paid the Escrow Money on pro rata basis determined
        according to the percentage of the Purchase Price under the Stock
        Purchase Agreement that would have been payable to the Sellers and the
        Escrow Agent shall release the Escrow Money to the Sellers on such pro
        rata basis.  Otherwise, ten (10) days after receipt of written
        notice/demand from the Purchaser to the Escrow Agent (certifying that
        such notice/demand has been furnished to Sellers) that one of the
        conditions stated in (i) or (ii) above has occurred and that the
        Purchaser is entitled to receive a refund of the Escrow Money, the
        Purchaser shall be entitled to be refunded the Escrow Money and the
        Escrow Agent shall release the Escrow Money to the Purchaser.

                 (c)     Automatic Termination.  In the event that the Escrow
        Agent has not received instructions as to the release of the Escrow
        Money before February 15, 1997,





                                       2
<PAGE>   3
        then this Escrow Agreement shall automatically terminate on February
        15, 1997 and the Escrow Agent shall refund the Escrow Money to
        Purchaser without the necessity of any further notice or instructions
        of any kind.

                 (d)     Interest.  Interest earned on the Escrow Money shall
        be applied together with the Escrow Money and paid to the Sellers or to
        Purchaser as the case may be as specified above.

        4.       Liability of Escrow Agent.  Purchaser and Sellers hereby agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and amenities of the Escrow Agent:

                 (a)     The Escrow Agent is not a party to, and is not bound
        by, or charged with notice of, any agreement out of which this escrow
        may arise.

                 (b)     The Escrow Agent acts hereunder as a depository only,
        and is not responsible or liable in any manner whatsoever for the
        sufficiency, correctness, genuineness or validity of the subject matter
        of the escrow, or any part thereof, or for the form or execution
        thereof, or for the identity or authority of any person executing or
        deposition the escrow or for any loss on any investment made pursuant
        to the provisions hereof.

                 (c)     The Escrow Agent shall be protected in acting upon any
        written notice, request, waiver, consent, certificate, receipt,
        authorization, power of attorney, or other paper or document which the
        Escrow Agent in good faith believes to be genuine and what it purports
        to be.

                 (d)     Purchaser and the Sellers, jointly and severally,
        agree to indemnify and hold the Escrow Agent harmless against any and
        all losses, claims, demands, liabilities and expenses, including
        attorney's fees and costs, which may be incurred by the Escrow Agent in
        connection with the acceptance and performance or non-performance of
        its duties hereunder whether such losses, claims, demands, liabilities
        and expenses arise during or subsequent to performance of this
        Agreement, directly or indirectly, excluding, however, any such
        liability resulting from its gross negligence or willful misconduct.
        In the event the Escrow Agent becomes involved in litigation in
        connection with this escrow, Purchaser and the Sellers, jointly and
        severally, agree to indemnify and save the Escrow Agent harmless from
        any and all losses, claims, damages, liabilities and expenses,
        including attorney's fees and costs, interpleader costs and judgments,
        which may be incurred or suffered by Escrow Agent as a result thereof,
        excluding, however, any such liability resulting from its gross
        negligence or willful misconduct.  It is the express intent of the
        Purchaser and the Sellers to indemnify and hold the Escrow Agent
        harmless against its own ordinary negligence.

                 (e)     In the event of any disagreement between any of the
        parties to this Agreement or with any third person resulting in adverse
        claims or demands being made





                                       3
<PAGE>   4
        in connection with the Escrow Money, or in the event the Escrow Agent
        in good faith is in doubt as to what action it should take hereunder,
        the Escrow Agent may, at its option, refuse to comply with any claims
        or demands on it, or refuse to take any other action hereunder, so long
        as such disagreement continues or doubt exists, and in such event, the
        Escrow Agent shall not be or become liable in any way or to any person
        for its failure or refusal to act, and the Escrow Agent shall be
        entitled to continue to so refrain from acting until (i) the rights of
        all the parties shall have been fully and finally adjudicated by a
        court of competent jurisdiction, or (ii) all differences shall have
        adjusted and all doubt resolved by agreement among all the interested
        parties and the Escrow Agent shall have been notified thereof pursuant
        to written directions duly executed by all such persons.  In the event
        of conflicting demands on the Escrow Agent, the Escrow Agent may, at
        its option, deposit any and all funds in question with the court that
        would have jurisdiction over the matter, and in such event, the Escrow
        Agent is relieved of any further responsibility in connection with this
        escrow.

                 (f)     Escrow Agent may consult with its counsel or other
        counsel satisfactory to it concerning any question relating to its
        duties or responsibilities hereunder or otherwise in connection
        herewith, and shall not be liable for any action taken, suffered or
        omitted by it in good faith upon the advice of such counsel.

                 (g)     Escrow Agent may resign hereunder upon thirty (30)
        days' prior notice to the Seller and Purchaser.  Upon the effective
        date of such resignation, Escrow Agent shall deliver the Escrow Money
        to any substitute escrow agent designated by Seller and Purchaser in
        writing.  If Seller and Purchaser fail to designate a substitute escrow
        agent within thirty (30) days after the giving of such notice, Escrow
        Agent may institute a petition for the appointment of a successor
        escrow agent hereunder.  Escrow Agent's sole responsibility after such
        30-day notice period expires shall be to hold the Escrow Money (without
        any obligation to reinvest the same) and to deliver the same to a
        designated substitute escrow agent, if any, or in accordance with the
        directions of a final order or judgment of a court of competent
        jurisdiction, at which time of delivery Escrow Agent's obligations
        hereunder shall cease and terminate.

        5.       Compensation of Escrow Agent.  As compensation for its
services hereunder, the Escrow Agent shall be entitled to the fees and expenses
set forth on Schedule 1 hereto.  All fees and expenses of the Escrow Agent
shall be paid equally by the Sellers and the Purchaser.  In the event any of
such fees and expenses are not paid when due, the Escrow Agent may offset the
amount of such unpaid fees and expenses against amounts in the Escrow Account.

        6.       Non-Waiver.  Nothing contained in this Agreement shall be
deemed or construed to release or waive any of the rights or obligations of
Purchaser or Sellers under the Stock Purchase Agreement, all rights and
remedies of Purchaser and Sellers under this Agreement are cumulative of all
other rights which either of them may have under the Stock Purchase Agreement,
by law or otherwise.

                                   ARTICLE 2
                               PURCHASE AND SALE

conditions of this Agreement and in reliance on the representations, warranties
and covenants herein set forth, at the Closing each Seller shall sell to

interests, voting agreements or trusts, encumbrances or other restrictions or

Sellers collectively deliver for purchase all the Shares.

       2.2       Purchase Price.  Subject to the terms and conditions of this
Agreement and in reliance on the representations, warranties and covenants
herein set forth, the Purchaser shall pay to the Sellers as consideration for
the Shares, an aggregate purchase price (the "Purchase Price") equal to:

                 (a)      Twelve Million Five Hundred Thousand Dollars
($12,500,000) less, however, the reduction to such amount applicable pursuant
to the provisions Section 8.1(h) of this Agreement (the "Initial Payment"); and

                 (b)      plus the Adjustment Amount (as hereinafter defined in
Section 2.3), if any, to be determined and paid in accordance with Section 2.3
below.

At the Closing Purchaser shall pay to the Sellers the Initial Payment by
certified or cashier's check (or by wire transfer of immediately available
funds to the accounts of the Sellers in accordance with written directions
provided to Purchaser by each Seller not less than two (2) business days prior
to the Closing Date).  The Initial Payment shall be allocated to each of the
Sellers in accordance with the percentages set forth on Exhibit A.

       2.3       Closing Financial Statements: Purchase Price Adjustment.

                 (a)      Attached hereto as a part of Schedule 2.3 is the pro
forma combined operating statement of the Company and the Kansas and Missouri
operations of the Purchaser for the six month period ended June 30, 1996 which
has been annualized for a full year of assumed combined operations (the "First
Year Operating Profit Statement").  The First Year





                                       2
<PAGE>   9
Operating Profit Statement has been prepared and calculated in accordance with
the principles, procedures and definitions set forth in Schedule 2.3.   As soon
as practicable following the end of the twenty-four (24) calendar month period
beginning with the first day of the calendar month after the calendar month in
which the Closing occurs but in no event later than sixty (60) days following
such date, Purchaser shall prepare a statement (the "Second Year Operating
Profit Statement") setting forth the operating profit of the Company as of the
end of the most recent twelve (12) month period ending as of the end of such
twenty-four (24) month period (the "Second Fiscal Year").  The Second Year
Operating Profit Statement shall be calculated and prepared in accordance with
the principles, procedures and definitions set forth on Schedule 2.3.  The
Second Year Operating Profit Statement shall be delivered to the Sellers not
more than sixty (60) days after the end of such twenty-four (24) month period.
The amount of the excess, if any, of the Operating Profit of the Second Fiscal
Year over the Operating Profit of the First Fiscal Year times 2.5 up to a
maximum of $2,000,000 shall be the "Adjustment Amount."  The Sellers and the
Purchaser have agreed, as reflected on Schedule 2.3 that the Operating Profit
for the First Fiscal Year shall be $1,136,000.

                 (b)      Within thirty (30) days after delivery of the Second
Year Operating Profit Statement by Purchaser, Sellers may deliver written
notice (the "Protest Notice") to Purchaser of any objections, and the basis
therefor, which the Sellers may have to the Second Year Operating Profit
Statement.  The failure of Sellers to deliver such Protest Notice within the
prescribed time period will constitute the acceptance of the Second Year
Operating Profit Statement as delivered by Purchaser by Sellers.  During the
ten (10) business days following receipt of the Protest Notice by Purchaser,
Purchaser and Sellers shall attempt to resolve any disagreement with respect to
the Second Year Operating Profit Statement and the appropriateness thereof.
If, at the end of the period specified in the immediately preceding sentence,
Purchaser and Sellers shall have failed to resolve the disagreement specified
in the Protest Notice, the items in dispute shall be referred to the Kansas
City office of Price Waterhouse L.L.P. or such other accounting firm of
national reputation as may be agreed to by the parties (the "Arbitrator") for
final determination within 45 days.  This provision for arbitration shall be
specifically enforceable by the parties and the determination of the Arbitrator
in accordance with the provisions hereof shall be final and binding upon
Purchaser and Seller with no right of appeal therefrom.  The fees and expenses
of the Arbitrator shall be paid by the party whose last proposed offer for
settlement of the items in dispute, taken as a whole, (which offer each party
shall submit to the other in writing prior to the commencement of arbitration)
was farther away from the final determination of the Arbitrator.

                 (c)      Purchaser agrees that within five (5) days after the
final determination of the Adjustment Amount as provided in this Section 2.3,
Purchaser shall pay the Adjustment Amount.  Purchaser and Sellers agree that
the Adjustment Amount shall be paid as follows:  the first $1,000,000 (or any
lesser amount) of the Adjustment Amount shall be paid to George C. Kopp, III
("Kopp"), and the balance of the Adjustment Amount in excess of $1,000,000, if
any, shall be paid 25% to Kopp and 75% to the Sellers in accordance with the
percentages set forth on Exhibit A.

connection with this Agreement or any of the transactions contemplated hereby.

       4.20      Labor Practices.  The Company has no collective bargaining or
other labor union agreements.  There is no unfair labor practice complaint
against the Company pending before the National Labor Relations Board, there is
no pending or, to the knowledge of the Individual Sellers, threatened labor

       4.24      Taxes.  All federal, state and other tax returns and reports
of the Company required by law to be filed have been prepared and properly
filed or valid extensions have been obtained, and all taxes, charges, fees,
duties, levies or other assessments which are imposed by the United States, or
any state, local or foreign government or subdivision or agency thereof,
including any interest, penalties or additions (collectively "Taxes") upon the
Company or any of its properties, assets or income which are due and payable or
claimed by any taxing authority to be due and payable have been paid.  The
liability for accrued taxes as shown in the Company Balance Sheet (net of
amounts reserved for deferred taxes) is sufficient for the payment of all
unpaid Taxes of the Company accrued for or applicable to the periods prior to
the Balance Sheet Date and all years and periods prior thereto and for which
the Company may at that date have been liable in its own right or by reason of
its being a member of any group of corporations filing consolidated tax returns
(including any such amounts payable as a result of an audit of any tax return
for any such period).  The Company utilizes the accrual method of accounting
for tax purposes.

       There are no claims for Taxes pending against the Company, and the
Individual Sellers do not know of any threatened claim for tax deficiencies or
any basis for such claims, and there are not now in force any waivers or
agreements by the Company for the extension of time for the assessment of any
tax, nor has any such waiver or agreement been requested by the Internal
Revenue Service (the "Service") or any other taxing authority.

       The Federal income tax returns of the Company have not been examined or
audited by the Service.  No material issues have been raised in any examination
by any taxing authority with respect to the businesses and operations of the
Company which, by application of similar principles, could be expected to
result in a proposed adjustment to the liability of the Company for taxes for
any other period not so examined.

       The Company has not filed a consent under Section 341(f) of the Internal
Revenue Code of 1986, as amended (the "Code") concerning collapsible
corporations.  The Company has not made any payments, is obligated to make any
payments, or is a party to any agreement that under certain circumstances could
obligate it to make any payments that will not be deductible under Section 280G
of the Code.  The Company has not been a United States real property holding
corporation within the meaning of Section 897(c)(2) of the Code during the
applicable period specified in Section 897(c)(1)(A)(ii) of the Code.  The
Company has disclosed on their federal income tax returns all positions taken
therein that could give rise to a substantial understatement of federal income
tax within the meaning of Section 6662 of the Code.  The Company is not a party
to any tax allocation or sharing agreement.  The Company (a) has not been a
member of an affiliated group filing a consolidated federal income tax return
and (b) has  no liability for the taxes of any person (other than any of the
Company) under Treas. Reg. Section  1.1502-6 (or any similar provision of
state, local, or foreign law), as a transferee or successor, by contract, or
otherwise.

       The Company has paid or are withholding and have or will pay when due to
the proper taxing authorities all withholding amounts and taxes required to be
withheld or paid for all income, unemployment, social security, medicare or
other similar Taxes programs or benefits





                                       16

with respect to wages, salary and other compensation of directors, officers and
employees of the Company.

       4.25      Transactions With Affiliates.  Except as set forth in Schedule
4.25, there are no loans, leases, agreements, contracts or other transactions
between the Company and any present or former stockholder, director or officer
of the Company, or any member of such stockholder's, director's or officer's
immediate family.  Except as set forth in Schedule 4.25, no stockholder,
director or officer of the Company nor any of their respective spouses or
family members owns directly or indirectly on an individual or joint basis any
material interest in, or serves as an officer or director of, or in any similar
capacity for, any competitor, customer, provider or supplier of the Company or
any organization which has a material contract or arrangement with the Company.

       4.26      Improper Payments.  To the knowledge of the Individual
Sellers, neither the Company, nor any director, officer, employee or agent of
the Company has made any improper bribes, kickbacks or other payments on behalf
of the Company to, or received any such payments from, customers, vendors,
suppliers or other persons contracting with the Company.

       4.27      Full Disclosure.  To the knowledge of the Individual Sellers,
this Agreement and the documents, certificates, and other writings furnished or
to be furnished by or on behalf of Sellers to Purchaser pursuant to the
provisions of this Agreement do not and will not contain any untrue statement
of a material fact or omit to state any material fact necessary to make the
statements made, in the light of the circumstances under which they are made,
not misleading.  To the knowledge of the Individual Sellers, there is no
material liability or obligation of the Company which relates to the agreements
and documents identified in the Schedules which is not generic to the
identified agreement or document and readily ascertainable from a review of
such agreement or document, and not otherwise disclosed herein or identified on
the face of the Schedules.

                                       21
<PAGE>   28
                 (xv)     The Company will not make any change in any method of
       reporting income or expenses for federal income tax purposes; and

                 (xvi)    The Company shall not knowingly take any action which

       of this Agreement.

       6.5       Consents and Approvals.  Unless Purchaser deems it inadvisable
to seek any such consent, approval or authorization (except with respect to any
consent, approval or authorization lawfully required to consummate this
transaction) and so advises the Company in writing, the Company will apply for
(or assist the Purchaser in applying for) or otherwise seek, and use its
reasonable best efforts to obtain, all consents, approvals and authorizations
of all governmental entities (other than applications for approval of a change
of control required to be filed in each state where the Company holds a
certificate of authority to operate a prepaid dental plan which shall be the
responsibility of Purchaser to prepare, file and obtain) and of all parties
with whom the Company has contractual or other relationships whose consent or
approval is necessary for the valid and effective consummation and completion
of the transactions contemplated hereby or is necessary in order that the
Company may validly, lawfully and effectively perform and carry out its
obligations hereunder without becoming in default under any agreement with any
party or subjecting the Company to any claim or penalty due to the failure to
obtain such consent which would have a materially adverse effect on the
business or operations of the Company.  With respect to any such consents which
Purchaser requests the Company not to seek as provided above, the Company will
cooperate with Purchaser to provide for Purchaser the benefits under any such
agreement (including enforcement thereof) at the sole cost and for the benefit
of Purchaser, and Purchaser will assume liabilities associated therewith.
Following the Effective Date, the Company will use its reasonable best efforts
to obtain all consents specifically identified by Purchaser as reasonably
necessary to continue the uninterrupted operation of the business of the
Company.  The Company shall use commercially reasonable efforts to obtain all
necessary consents and approvals required for its performance of this Agreement
and the transactions contemplated hereby, including, without limitation, the
consents listed on Schedule 4.22 other than the regulatory change of control
approvals to be obtained by Purchaser.  The Company shall make all filings,
applications, statements and reports to all governmental authorities which are
required to be made prior to the Closing Date by or on





                                       22
<PAGE>   29
behalf of the Sellers or the Company pursuant to any applicable statute, rule
or regulation in connection with this Agreement and the transactions
contemplated hereby.  As required in connection with the performance of this
Agreement by the Company, the Company will promptly provide such other
information and communications to governmental and regulatory authorities,
including, without limitation, insurance regulatory authorities in any
jurisdiction in which the Company conducts business, as such regulatory
authorities or Purchaser may reasonably request.  Between the date hereof and
the Closing Date, the Company shall promptly provide Purchaser with copies of
all correspondence and filings to or from all governmental and regulatory
bodies and officials relating to the Company.

       6.6       Publicity.  Prior to the Closing, any public statement or
announcement by the Sellers or Company, including but not limited to any
written news releases, pertaining to this Agreement or the transactions
contemplated thereby shall be submitted to Purchaser for review and approval
prior to the release by the Company, and shall be released only in a form
approved by Purchaser, provided, however, that (i) such approval shall not be
unreasonably withheld and (ii) such review and approval shall not be required
of statements and announcements if prior review and approval would prevent the
timely and accurate dissemination of such statements and announcements as
required to comply, in the judgement of counsel, with any applicable law, rule
or policy.  The Company and Purchaser shall issue a press release regarding the
execution of this Agreement within one day of the date hereof or such other
time as the Company and Purchaser may mutually agree.

       6.7       Financial Information.  The Individual Sellers will cause the
Company to, and the Company will, deliver as soon as reasonably practicable to
Purchaser unaudited financial statements of the Company for each month from and
after the date hereof as and when such financial statements become available in
the usual course of business.

       6.8       Expenses.  All costs and expenses incurred by the Company or
the Individual Sellers in connection with this Agreement shall be paid by the
Company on or prior to the Closing Date; provided, however, that the condition
precedent specified in Section 9.1(k) must be satisfied on the Closing Date
after taking into account the payment of such costs and expenses by the
Company.

       6.9       Breach of Representations and Warranties.  Promptly upon any
Individual Seller or the Company becoming aware of any breach of any of the
representations and warranties of the Sellers contained in this Agreement, or
any event which would cause the Sellers to be unable to deliver the
certificates contemplated by Section 9.1(e) hereof, the Individual Sellers
shall give detailed written notice thereof to the Purchaser and shall use all
commercially reasonable efforts to prevent or promptly remedy the same.

       6.10      No Transfer of Shares.  Unless and until this Agreement is
terminated, each Seller shall not, directly or indirectly, exchange, transfer,

       6.11      Updating of Exhibits and Schedules.  The Individual Sellers
shall notify Purchaser of any changes, additions, or events which may cause any
change in or addition to the Schedules delivered by them under this Agreement
promptly after the occurrence of the same and again at the Closing by delivery
of appropriate updates to all such Schedules.  No notification of a change or
addition to a Schedule made pursuant to this Section shall be deemed to cure
any breach of any representation or warranty resulting from such change or
addition unless Purchaser specifically agrees thereto in writing, nor shall any
such notification be considered to constitute or give rise to a waiver by
Purchaser of any condition set forth in this Agreement; provided, however, that
the closing of the purchase and sale of the Shares hereunder by Purchaser shall
be deemed to constitute Purchaser's acceptance of any written updates to the
Schedules provided by the Company or any of the Sellers prior to the Closing
Date and the waiver of any breach of any representation or warranty or
misstatement in the original Schedules that is disclosed in or corrected by
such updated Schedules.  Purchaser shall not be deemed to have waived any
misrepresentation or breach of warranty unless and except Purchaser has actual
knowledge of such misrepresentation or breach of warranty.

       6.12      Contribution.  The Individual Sellers agree among themselves
to contribute on an equal one-third basis to the satisfaction of any valid
claims of Purchaser for indemnification under Article 11.  Nothing contained in
this Section 6.12 shall limit the right of Purchaser to seek indemnification
from any one Individual Seller for the full amount Purchaser is entitled to
receive for indemnification hereunder.

its representatives to, deliver to the Company all documents and other written
materials, and all copies thereof, obtained by Purchaser or on its behalf from
the Sellers or the Company as a result of this Agreement or in connection

agrees that the Company shall have standing and may avail itself of any remedy
at law or in equity, including an action for injunctive relief, in the event of
a breach or threatened breach by Purchaser of any of the provisions of this
Section 7.5.   The obligations of Purchaser under this Section 7.5 shall

the timely and accurate dissemination of such statements and announcements as
requested to comply, in the judgment of counsel, with any applicable law, rule
or policy.  The Company and Purchasers shall issue a press release regarding
the execution and delivery of this Agreement within one day after the date
hereof or such other time as the Company and Purchaser may mutually agree.

       7.7       Control of Audits.  Purchaser shall afford the Individual
Sellers the opportunity to control any audit of the Tax returns of the Company

                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       11.1      Representations and Warranties to Survive.  All
representations, warranties, covenants and agreements made by the parties each
to the other in this Agreement shall be true at the Closing and shall survive
the consummation of this Agreement and the Closing hereunder for a period of
two years, ending at midnight on the second anniversary of the Closing Date;

representation or warranty and no representation or warranty shall be merged

the face of the Schedules or is otherwise expressly set forth herein, such
information shall be deemed to amend, limit and/or restate any representation

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers and the Company
       under this Agreement or under any other agreement or document delivered
       by the Sellers at Closing hereunder;

                 (ii)     Any liabilities or obligations or claims of any kind
       arising out of or resulting from the termination and cancellation of the
       Kopp stock option and employment agreement or the Dlabal stock option
       and employment agreement; and

                 (iii)    Any liabilities, obligations, fines or penalties of
       any kind arising out of, or resulting from, the matter set forth in
       Paragraph 5 of Schedule 4.5 to this Agreement; and

                 (iv)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold each
Seller harmless from, against, and in respect of, any loss, liability, claim,
demand, or expense, including but not limited to attorney's fees and costs, of
any kind whatsoever, arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Sellers at Closing hereunder;

                 (ii)     Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Sellers are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 11.2(a) above; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       11.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
11.2(a) or 11.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might result in any such claim, demand or
action, such party shall promptly notify the other party or parties who would
be obligated to provide indemnity hereunder with respect to such claim, demand
or action, and such other party or parties shall have the right to take such
action as it or they may deem appropriate to resolve such matter.  The
indemnified party or parties shall have the right to employ  separate counsel
in any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties, unless the employment of such counsel has been specifically





                                       33
<PAGE>   40
authorized by the indemnifying party or parties.  Any settlement of any action
subject to indemnity hereunder shall require the consent of the indemnified and
the indemnifying party which consent shall not be unreasonably withheld and
shall be given within ten (10) days following the giving of notice thereof.
The indemnifying party or parties shall not be liable for any settlement of any
action effected without its or their consent, but if settled with the consent
of the indemnifying party or parties or if there be a final judgment for the
plaintiff in any such action, the indemnifying party or parties shall indemnify
and hold harmless the indemnified party from and against any loss or liability
by reason of such settlement or judgment.  If requested by the indemnifying
party, the indemnified party shall cooperate with the indemnifying party and
its counsel and use its best efforts in contesting any such claim or, if
appropriate, in making any counter-claim or cross-complaint against the party
asserting the claim, provided that the indemnifying party will reimburse the
indemnified party for reasonable expenses incurred in so cooperating upon
presentation of receipts or other evidence of such expense.  The indemnifying
party and its representatives shall have full and complete access during
reasonable hours to all books, records and files of the indemnified party
expressly related to the defense of any claim for indemnification undertaken by
the indemnifying party pursuant to this Article 11, or for any other purpose in
connection therewith; provided that the indemnifying party shall safeguard and
maintain the confidentiality of all such books, records and files.

       11.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Individual Sellers
nor the Purchaser shall be obligated to indemnify the other party except to the
extent that the cumulative amount of all indemnifiable losses exceeds Twenty-
Five Thousand Dollars ($25,000.00) (the "Threshold"), which excess amount shall
be recoverable in accordance with the terms hereof; provided, however, that the
$25,000 limitation set forth in this Section 11.4(a) shall not apply to the
matters described in Section 11.4(c).  With respect to any indemnifiable loss
payable by the Individual Sellers, the funds in the Post-Closing Escrow Account
shall be used for such purpose first before any recovery is sought directly
from an Individual Seller; provided, however, that to the extent the
indemnification loss or losses exceed the funds in the Post-Closing Escrow
Account, then the Purchaser may seek recovery of the amount of such
indemnifiable loss in excess of such funds contemporaneously with the recovery
of any funds in the Post-Closing Escrow Account.

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 11.1 and this Section 11.4(b) shall not apply
to the matters described otherwise in Section 11.1 and Section 11.4(c) as to
which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party shall have given notice of such facts to the indemnifying
party and made a claim for





                                       34
<PAGE>   41
indemnification within such two-year period, then the right to indemnification
with respect thereto shall remain in effect until such matter shall have been
finally determined and disposed of and any indemnification due in respect
thereof shall have been paid.

                 (c)      Certain Matters.  The following are the matters 
referred to in Sections 11.1, 11.4(a) and Section 11.4(b):

                 (i)      Losses arising from fraud or an intentional
       misrepresentation on the part of any Seller or Purchaser; and

                 (ii)     Losses arising from the intentional breach of any
       covenant or agreement by a Seller or Purchaser contained in this
       Agreement.

       11.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Sellers and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.




                                   ARTICLE 12
                                NON-COMPETITION

       12.1      Covenant Not to Compete; Non-Solicitation.  For and in
consideration of the purchase by the Purchaser of the Shares pursuant to this
Agreement, and the payments payable by the Purchaser pursuant to this
Agreement, each Individual Seller covenants and agrees that he shall not,
directly or indirectly, as an employer, consultant, creditor, investor, owner,
agent, principal, partner, shareholder, or through any other kind of ownership
(other than ownership of securities of any publicly held entity in which the
Individual Seller, directly or indirectly, in the aggregate beneficially owns
less than two percent (2%) of any class of outstanding securities), or in any
other representative or individual capacity, do any of the following:

                 (i)      for a period of three (3) years from the date of this
       Agreement, engage in (i) the operation of a dental health indemnity
       insurance company, (ii) the operation of prepaid dental plans and dental
       preferred provider organizations, and (iii) the provision of management,
       administrative and related services to dental health indemnity insurance
       carriers, dental preferred provider organizations, and prepaid dental
       plans (collectively the





                                       35
<PAGE>   42
       "Dental Services Business") in the States of Missouri, Kansas and each
       state contiguous to the States of Missouri and Kansas (the "Restricted
       Area");

                 (ii)     for a period of three (3) years from the date of this
       Agreement, engage in any business which calls upon, solicits, diverts or
       takes away any customer or customers of the Company in the Restricted
       Area for the purpose of selling or attempting to sell to any of said
       customers any products or services similar to any products or services
       heretofore sold or provided to any of such customers by the Company; and

                 (iii)    for a period of three (3) years from the date of this
       Agreement, engage in any business which solicits any present or future
       employee of the Company or initiates discussions with any such employee
       regarding his or her termination or resignation from employment with the
       Company, so that such employee may accept employment with, or engagement
       as a partner, investor, shareholder, employee, agent or consultant with
       Individual Seller, directly or indirectly, as specified above; provided,
       however, that Individual Seller shall not be prohibited by this
       Agreement from employing or soliciting the employment of any employee
       that the Company terminates after the date of such termination;

provided, however, that the term "Dental Services Business" shall not include,
and this Section 12.1 shall not preclude Dlabal, directly or indirectly, from
continuing to provide professional dental care services to any person or
individual, or from entering into agreements to provide professional dental
care services for or on behalf of any other prepaid dental plan, dental health
indemnity insurance company or dental preferred provider organization.

                 12.2     Non-Disclosure.  Each Individual Seller covenants and
agrees that all information concerning the Company, including without
limitation (i) information regarding prices or premiums charged for products
and services, (ii) the assets, liabilities and financial condition of the
Company, (iii) the names and identities of customers and analyses of the amount
and types of products and services purchased by each such customer, (iv) the
dental health providers utilized by the Company and the financial arrangements
with such providers, and (v) the amount of compensation to employees,
constitute trade secrets and confidential, proprietary business information
which is the property of the Company and that, unless otherwise required by
law, from and after the date of this Agreement:

                 (a)      Each Individual Seller shall not, directly or
       indirectly, use, sell, license, publish, disclose or otherwise transfer
       or make available to others any of such trade secrets or confidential,
       proprietary information;

                 (b)      Without the prior written consent of the Company,
       each Individual Seller shall not, directly or indirectly, disclose any
       of such trade secrets or confidential, proprietary information; and





                                       36
<PAGE>   43
                 (c)      Each Individual Seller shall not, directly or
       indirectly, use for his own benefit or for the benefit of another, any
       of such trade secrets or confidential, proprietary information.

It is expressly understood, however, that the foregoing shall not apply to any
information that was generally available to the public on a non-confidential
basis prior to the date of this Agreement or was or becomes generally available
to the public on a non-confidential basis from a third party who is not bound
to keep such information confidential.

         12.3    Reasonableness; Reformation.  Each Individual Seller
acknowledges and agrees that (i) the provisions of this Article 12 are
ancillary to the transaction pursuant to which the Sellers sold and the
Purchaser acquired the Shares, (ii) the provisions of this Agreement contain
reasonable limitations as to time, geographical area and scope of activities to
be restrained and do not impose a greater restraint than is necessary to
protect goodwill and other business interests of the Company, (iii) if any
portion of the covenants and agreements set forth in this Agreement are held to
be invalid, unreasonable, arbitrary or against public policy, then such portion
of such covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, and (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against public policy, a lesser time
period, scope of activities covered, and/or geographical area which is
determined to be reasonable, non-arbitrary and not against public policy may be
enforced against each Individual Seller.

         12.4    Remedies for Breach.  If an Individual Seller has failed to
satisfactorily cure any breach or threatened breach of any covenant or
agreement contained herein within ten (10) days after written notice of such
breach or threatened breach given by the Purchaser to each Individual Seller,
any one or more of the following remedies, as selected by the Purchaser in its
sole discretion, shall be available to the Purchaser in the event of a breach
of this Agreement by the Individual Seller hereunder:

                 (a)      Specific Performance.  In the event of a breach or
         threatened breach of any covenant or agreement of an Individual Seller
         in this Agreement, remedies at law will not adequately compensate the
         Purchaser for its injuries incurred as a result  thereof.
         Accordingly, injunctive and/or equitable relief shall be available to
         the Purchaser to specifically enforce this Agreement and prevent such
         breach and any continued breach of any covenant and agreement herein.
         Such Individual Seller agrees that a bond of no more than $10,000 in
         the aggregate will provide adequate protection to such Seller and
         therefore no more than $10,000 in bond or other security shall be
         required to be posted by the Company by any court in any proceeding to
         obtain such injunctive or equitable relief.





                                       37
<PAGE>   44
                 (b)      Suit for Damages.  In addition to the remedies stated
         in Section 12.5(a) above, in the event of any breach of any covenant
         or agreement of a Seller herein, Purchaser may sue for damages arising
         out of such breach and otherwise enforce this Agreement and obtain all
         other remedies available to the Purchaser under applicable law.


                                   ARTICLE 13

and the Sellers;

                 (b)      By Purchaser or Sellers: Condition Precedent.  By
Purchaser or Sellers, upon written notice to the other, if the conditions to
the obligations of such canceling party or parties to consummate the
transaction, in the case of the Sellers, as provided in Article 8 or, in the
case of Purchaser, as provided in Article 9, were not, or cannot reasonably be,
satisfied on or before ninety (90) days after the date of this Agreement unless
the failure of the condition is the result of the material breach of this
Agreement by the party seeking to terminate; provided, however, that, in the
event all such conditions have been satisfied except solely the condition with
respect to obtaining all required consents, authorizations, and approvals of
governmental and regulatory agencies set forth in Sections 8.1(a) and 9.1(a),
respectively, and such failure is not due to a breach of this Agreement by the
non-terminating party, such date shall be automatically extended for three (3)
consecutive thirty (30) day periods provided, however, that in no event shall
such date be extended beyond an aggregate of one hundred eighty (180) days
after the date of this Agreement unless extended by the mutual agreement of the
Purchaser and the Sellers;

                 (c)      By Purchaser or Sellers: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Sellers, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) one hundred eighty
(180) days after the date of this Agreement, unless such date is extended by
mutual agreement of Purchaser and Sellers.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Sellers,
Sellers shall be entitled to retain the Earnest Money.  Any public announcement
of





                                       38
<PAGE>   45
the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

         13.2    Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Sellers, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

Any party may change the address or facsimile telephone number for notices to
be sent to it by written notice delivered pursuant to the terms of this Section
15.2.

         15.3    Entire Agreement; Amendments.  This Agreement and the
documents to be delivered at Closing hereunder set forth the entire
understanding of the parties and supersede all prior agreements or
understandings, whether written or oral, with respect to the subject matter
hereof.  This Agreement may be amended, modified or supplemented only by a
written agreement executed by Purchaser and Sellers.

         15.4    Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any Affiliate of
Purchaser without the necessity of seeking the consent of the Sellers;
provided, however, that Purchaser shall not be relieved of any obligations as a
result of such assignment and that, in addition to Purchaser remaining liable,
any such assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  None of the Sellers shall be entitled to
assign any of their respective rights or obligations under this Agreement;
provided, however, that the rights and obligations of a Seller may be assigned
by operation of law or may be assigned to an individual retirement account,
pension plan, trust or other entity under the

control of such Seller or the remainder beneficiary of any charitable remainder
trust upon the death of all the noncharitable income beneficiaries, but any
such assignment shall not relieve or release such Seller of any obligations
hereunder as a result of such assignment and that, in addition to such Seller
remaining liable, any such assignee shall assume and become liable for any and
all of such Seller's obligations under this Agreement.  In connection with any
such assignment, a Seller may transfer all or any portion of the Shares owned
by the Seller and thereby effect an assignment on the basis specified above.

         15.5    Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

         15.7    Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

         15.8    Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

         15.9    Time.  Time is of the essence under this Agreement.

         15.10   Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
Missouri.

         15.11   Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

         This Employment Agreement (this "Agreement") is made as of __________,
1996 (the "Effective Date"), by and between Kansas City Dental Care, Inc., a
Missouri corporation acting by and through its hereunto duly authorized officer
(the "Company"), and George C. Kopp, III (the "Executive").

         WHEREAS, the Company desires to employ the Executive and the Executive
is willing to render his services to the Company on the terms and conditions
with respect to such employment hereinafter set forth;

         NOW, THEREFORE, in consideration of premises and the mutual terms and
conditions hereof, the Company and the Executive hereby agree as follows:

         1. Employment. The Company hereby employs the Executive and the
Executive hereby accepts employment with the Company upon the terms and
conditions hereinafter set forth.

         2. Exclusive Services. The Executive shall devote his primary time,
ability and attention to the business of the Company during regular working
hours for the term of this Agreement. The Executive is engaged as a full-time
employee of the Company and is expected to devote his primary efforts to the
business of the Company during regular working hours. The Executive will not
render services to any other person that will cause the Executive not to be
available for full-time service to the Company. The Company acknowledges that
the Executive may now or hereafter have other business interests and/or
investments (including those set forth in Section 10(a)) that may require the
Executive's time, attention and energies, which pursuits shall not be precluded
by this Agreement so long as they are in accordance with the immediately
preceding sentence.

         3. Duties. The Executive is hereby employed by the Company and shall
render his services at the principal business offices of the Company located in
Kansas City, Missouri. The Executive shall be under no obligation to relocate
to any office of the Company outside of Jackson County, Missouri or Johnson
County, Kansas. The Executive shall have such authority and shall perform such
duties as are specified by the President of the Company; subject, however, to
such limitations, instructions, directions, and control as the Board may
specify from time to time in its sole discretion.

         4. Term. This Agreement shall have a term of three (3) years
commencing as of the Effective Date, subject to earlier termination as
hereinafter provided.

         5. Compensation. As compensation for his services rendered under this
Agreement, the Executive shall be entitled to receive the following:

                  (a) Base Salary. The Executive shall initially be paid a base
         annual salary of One Hundred Fifty Thousand and No/100 Dollars
         ($150,000) per year, payable in installments on the regular payroll
         dates of each month for the Company during the term of this Agreement,
         prorated for any partial employment month. Such base annual salary
         shall be subject to increase from time to time as authorized by the
         Board of Directors of the Company (the "Board") in its sole
         discretion.

                  (b) Additional Compensation. The Executive shall be paid such
         additional compensation and bonuses, if any, as may be determined in
         the sole discretion of the Board.

         6. Benefits. In addition to the compensation to be paid to the
Executive pursuant to Paragraph 5 hereof, the Executive shall further be
included in any hospital, surgical, and medical benefit plan, any group term
life insurance policy, any pension or profit sharing plan, and all other
benefits which may be extended from time to time to employees of the Company
generally by the Board in its sole discretion. The Executive shall be entitled
to four (4) weeks of vacation leave each calendar year.

         7. Reimbursement of Expenses. Subject to such rules and procedures as
from time to time are specified by the Company acting by and through the
President of the Company and/or the Board, the Company shall reimburse the
Executive on a monthly basis for reasonable business expenses necessarily
incurred in the performance of his duties under this Agreement.

         8. Confidentiality/Trade Secrets. The Executive acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and for a period of two (2)
years thereafter, the Executive covenants and agrees as follows:

                  (a) that he shall use the efforts and diligence of a
         reasonable business person in the protection of his own trade secrets
         and confidential and proprietary information to protect and safeguard
         the trade secrets and confidential and proprietary information of the
         Company including but not limited to the identity of its customers and
         suppliers, its arrangements with customers and suppliers, and its
         technical data, records, compilations of information, processes, and

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         9. Intellectual Property. The Executive covenants and agrees that he
will fully inform and disclose to the Company all inventions, designs,
improvements, discoveries and processes ("Inventions") which he has now or may
hereafter have during his employment with the Company and which pertain or
relate to the business of the Company or to any experimental work, products,
services or processes of the Company in progress or planned for the future,
whether conceived by the Executive alone or with others and whether or not
conceived during regular working hours. All such Inventions shall be the
exclusive property of the Company. The Executive shall assist the Company, at
any time during or after his employment, in perfecting its rights in all
Inventions and shall execute all documents and do all things necessary to vest
the Company with full and exclusive title thereto and to protect the same
against infringement by others. If such assistance takes place after his
employment is terminated the Executive shall be paid by the Company at a
reasonable rate for any time actually spent in rendering such assistance at the
request of the Company.

         10. Non-Competition.

                  (a) The Executive covenants and agrees that, during the
         period of his employment, he shall not, without the prior written
         consent of the Board, directly or indirectly, as an employee,
         employer, consultant, agent, principal, partner, shareholder,
         corporate officer, director, or through any other kind of ownership
         (other than ownership of securities of publicly held corporations of
         which the Executive owns less than two percent (2%) of any class of
         outstanding securities) or in any other representative or individual
         capacity, engage in any business or render any services to any
         business that is in competition in any manner whatsoever with the
         business of the Company. The Executive has disclosed to the Company
         his interest in and participation with Direct Dental Care, Inc.,
         Dental Care Management Company and Midwest Dental Care, Inc., and his
         continuing participation therein shall not violate this Section 10 so
         long as none of such companies engages in the prepaid dental plan
         business, the dental health indemnity insurance business or the dental
         preferred provider organization business.

                  (b) In addition, after termination of this Agreement, the
         Executive covenants and agrees that, for the period that the Company
         is continuing to make severance payments pursuant to Section 12(c)
         below, if applicable, or, in the event of the

         termination of this Agreement by the Company with cause, for the
         remaining term of this Agreement after the date of termination, he
         shall not directly or indirectly, as an employee, employer,
         consultant, creditor, investor, owner, agent, principal, partner,
         shareholder, corporate officer, director or through any other kind of
         ownership (other than ownership of securities of any publicly held
         entity in which Executive, directly or indirectly, in the aggregate
         owns less than two percent (2%) of any class of outstanding
         securities), or in any other representative or individual capacity, do
         any of the following:

                           (i) engage in the dental services business in the
                  States of Missouri or Kansas, or any state contiguous to the
                  States of Kansas and Missouri (the "Restricted Area") that is
                  in competition in any manner whatsoever with the dental
                  services business conducted by the Company, including,
                  without limitation, the business of a dental health indemnity
                  insurance company, a prepaid dental plan, a dental preferred
                  provider organization, a dental referral plan or the
                  provision of management, administrative, or related services
                  to any of the foregoing anywhere in the Restricted Area;

                           (ii) engage in any business which calls upon,
                  solicits, diverts or takes away any customer or customers of
                  the Company in the Restricted Area for the purpose of selling
                  or attempting to sell to any of said customers any products
                  or services similar to any products or services heretofore
                  sold or provided to any of such customers by the Company;

                           (iii) engage in any business which solicits any
                  present or future employee of the Company or initiates
                  discussions with any such employee regarding his or his
                  termination or resignation from employment with the Company,
                  so that such employee may accept employment with, or
                  engagement as a partner, investor, shareholder, employee,
                  agent or consultant with Executive, directly or indirectly,
                  as specified above; provided, however, that Executive shall
                  not be prohibited by this Agreement from employing or
                  soliciting the employment of any employee that the Company
                  terminates after the date of such termination; and

                           (iv) make or publish any statement, written or oral,
                  disparaging the reputation of the Company or its
                  subsidiaries, executive officers or any of its business
                  services or products or solicit or encourage any member of
                  any prepaid dental plan of the Company or its subsidiaries or
                  any third party having a group agreement with the Company or
                  its subsidiaries to terminate the membership of such person
                  in the plan of the Company or its subsidiaries or to
                  terminate such group agreement.

                  (d) In its sole discretion, the Company shall have the right
         at any time and from time to time, evidenced solely by the written
         approval of the Board of Directors of the Company, to waive all or any
         portion of the rights of the Company under the covenants not to
         compete contained in this Agreement as applicable to Executive,



                                       4
<PAGE>   56



         including, without limitation, reducing the scope of covenant not to
         compete applicable to Executive or reducing the time period or the
         geographical area of the covenant not to compete applicable to
         Executive; provided that as so amended by waiver such covenant not to
         compete shall remain fully in effect. In order to be effective, any
         such waiver must be in writing, approved by the Board of Directors of
         the Company as provided above, and executed by an authorized officer
         of the Company.

                  (e) Executive acknowledges and agrees that the provisions of
         this Agreement contain reasonable limitations as to time, geographical
         area and scope of activities to be restrained and do not impose a
         greater restraint than is necessary to protect goodwill and other
         business interests of the Company and its subsidiaries, (iii) if any
         portion of the covenants and agreements set forth in this Agreement
         are held to be invalid, unreasonable, arbitrary or against public
         policy, then such portion of such covenants shall be considered
         divisible as to time, scope of activities covered, and geographical
         area, (iv) if any court of competent jurisdiction determines the
         specified time period, scope of activities covered, or the specified
         geographical area applicable to any provision of this Agreement to be
         invalid, unreasonable, arbitrary or against public policy, a lesser
         time period, scope of activities covered, and/or geographical area
         which is determined to be reasonable, non-arbitrary and not against
         public policy may be enforced against Executive.

         11. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8, 9 and 10 of this Agreement shall continue to be
binding upon the Executive, notwithstanding the termination of his employment
with the Company for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement and any other agreement between the Company and the Executive. The
existence of any claim or cause of action by the Executive against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of any or all of such covenants. It
is expressly agreed that the remedy at law for the breach of any such covenant
is inadequate and the injunctive relief shall be available to prevent to the
breach or any threatened breach thereof.

         12. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         thirty (30) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon thirty (30) days prior written notice to the Executive.



                                       5
<PAGE>   57



                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:

                           (1) If the Executive becomes disabled for a period
                  of more than ninety (90) consecutive days (for the purposes
                  hereof, "disabled" shall have the same meaning as is provided
                  for such term in the group long-term disability insurance
                  policy maintained by the Company on the Effective Date);

                           (2) If the Executive for reasons other than
                  vacation, illness or injury absents himself from his duties
                  without the consent of the Board for more than ten (10)
                  consecutive days;

                           (3) If the Executive should die (effective on the
                  date of death);

                           (4) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (5) If the Executive should willfully breach or,
                  after written notice from the Company, habitually neglect his
                  duties which he is required to perform under this Agreement
                  or otherwise fail to comply with the terms and conditions of
                  this Agreement specifically including, but not limited to,
                  the covenants set forth in Paragraphs 8, 9 and 10 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by his prior to the date of termination as provided herein
computed on a pro rata basis to and including such date of termination. In the
event the Company terminates this Agreement without cause pursuant to Paragraph
12(b) above, the Executive shall be entitled to receive a severance payment as
liquidated damages for, and in lieu of, any and all damages which he may incur
as a result of such termination in an amount equal to his basic salary as
specified in Paragraph 5(a) as then in effect on the date of termination over
the remaining term of this Agreement. Such severance payment shall be payable
in installments on the same dates that such payments would have been made
during the term of this Agreement. In addition, in such event, the Company
shall continue to pay for the group health and life insurance provided for the
Executive on the date of termination until the end of the original term of this
Agreement. The Executive shall be entitled to no further compensation as of the
date of termination of this Agreement specifically including but not limited to
any unearned bonuses under this Agreement. Any termination of this Agreement
shall be without prejudice to any right or remedy to which the terminating
party may be entitled either at law, in equity, or under this Agreement.

         13. Notices. Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this

         held to be illegal, invalid, or unenforceable under present or future

         This Employment Agreement (this "Agreement") is made as of __________,
1996 (the "Effective Date"), by and between Kansas City Dental Care, Inc., a
Missouri corporation acting by and through its hereunto duly authorized officer
(the "Company"), and John E. Carlin, Ph.D.

hours for the term of this Agreement. The Executive is engaged as a full-time
employee of the Company and is expected to devote his primary efforts to the

render services to any other person that will cause the Executive not to be
available for full-time service to the Company. The Company acknowledges that
the Executive may now or hereafter have other business interests and/or
investments (including those set forth in Section 10(a)) that may require the
Executive's time, attention and energies, which pursuits shall not be precluded
by this Agreement so long as they are in accordance with the immediately
preceding sentence.

         3. Duties. The Executive is hereby employed by the Company and shall
render his services at the business office of the Company located in Manhattan,
Kansas. The Executive shall be under no obligation to relocate to any other

perform such duties as are specified by the President of the Company; subject,
however, to such limitations, instructions, directions, and control as the

         4. Term. This Agreement shall have a term of three (3) years
commencing as of the Effective Date, subject to earlier termination as

         5. Compensation. As compensation for his services rendered under this
Agreement, the Executive shall be entitled to receive the following:

                  (a) Base Salary. The Executive shall initially be paid a base
         annual salary of One Hundred Fifty Thousand and No/100 Dollars

         dates of each month for the Company during the term of this Agreement,
         prorated for any partial employment month. Such base annual salary
         shall be subject to increase from time to time as authorized by the
         Board of Directors of the Company (the "Board") in its sole
         discretion.

                  (b) Additional Compensation. The Executive shall be paid such
         additional compensation and bonuses, if any, as may be determined in
         the sole discretion of the Board.

trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and for a period of two (2)
years thereafter, the Executive covenants and agrees as follows:

                  (a) that he shall use the efforts and diligence of a
         reasonable business person in the protection of his own trade secrets
         and confidential and proprietary information to protect and safeguard
         the trade secrets and confidential and proprietary information of the
         Company including but not limited to the identity of its customers and
         suppliers, its arrangements with customers and suppliers, and its
         technical data, records, compilations of information, processes, and
         specifications relating to its customers, suppliers, products and
         services;

                  (b) that he shall not disclose any of such trade secrets and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         9. Intellectual Property. The Executive covenants and agrees that he
will fully inform and disclose to the Company all inventions, designs,
improvements, discoveries and processes ("Inventions") which he has now or may
hereafter have during his employment with the Company and which pertain or
relate to the business of the Company or to any experimental work, products,
services or processes of the Company in progress or planned for the future,
whether conceived by the Executive alone or with others and whether or not
conceived during regular working hours. All such Inventions shall be the
exclusive property of the Company. The Executive shall assist the Company, at
any time during or after his employment, in perfecting its rights in all
Inventions and shall execute all documents and do all things necessary to vest
the Company with full and exclusive title thereto and to protect the same
against infringement by others. If such assistance takes place after his
employment is terminated the Executive shall be paid by the Company at a
reasonable rate for any time actually spent in rendering such assistance at the
request of the Company.

         10. Non-Competition.

                  (a) The Executive covenants and agrees that, during the
         period of his employment, he shall not, without the prior written
         consent of the Board, directly or indirectly, as an employee,
         employer, consultant, agent, principal, partner, shareholder,
         corporate officer, director, or through any other kind of ownership
         (other than ownership of securities of publicly held corporations of
         which the Executive owns less than two percent (2%) of any class of
         outstanding securities) or in any other representative or individual
         capacity, engage in any business or render any services to any
         business that is in competition in any manner whatsoever with the
         business of the Company. The Executive has disclosed to the Company
         his interest in and participation with Direct Dental Care, Inc.,
         Dental Care Management Company and Midwest Dental Care, Inc., and his
         continuing participation therein shall not violate this Section 10 so
         long as none of such companies engages in the prepaid dental plan
         business, the dental health indemnity insurance business or the dental
         preferred provider organization business.

                  (b) In addition, after termination of this Agreement, the
         Executive covenants and agrees that, for the period that the Company
         is continuing to make severance payments pursuant to Section 12(c)
         below, if applicable, or, in the event of the termination of this
         Agreement by the Company with cause for the remaining term of this
         Agreement after the date of termination, he shall not directly or
         indirectly, as an employee, employer, consultant, creditor, investor,
         owner, agent, principal, partner, 



                                       3

         shareholder, corporate officer, director or through any other kind of
         ownership (other than ownership of securities of any publicly held
         entity in which Executive, directly or indirectly, in the aggregate
         owns less than two percent (2%) of any class of outstanding
         securities), or in any other representative or individual capacity, do
         any of the following:

                           (i) engage in the dental services business in the
                  States of Missouri or Kansas or any state contiguous to the
                  States of Kansas and Missouri (the "Restricted Area") that is
                  in competition in any manner whatsoever with the dental
                  services business conducted by the Company, including,
                  without limitation, the business of a dental health indemnity
                  insurance company, a prepaid dental plan, a dental preferred
                  provider organization, a dental referral plan or the
                  provision of management, administrative, or related services
                  to any of the foregoing anywhere in the Restricted Area;

                           (ii) engage in any business which calls upon,
                  solicits, diverts or takes away any customer or customers of
                  the Company in the Restricted Area for the purpose of selling
                  or attempting to sell to any of said customers any products
                  or services similar to any products or services heretofore
                  sold or provided to any of such customers by the Company;

                           (iii) engage in any business which solicits any
                  present or future employee of the Company or initiates
                  discussions with any such employee regarding his or his
                  termination or resignation from employment with the Company,
                  so that such employee may accept employment with, or
                  engagement as a partner, investor, shareholder, employee,
                  agent or consultant with Executive, directly or indirectly,
                  as specified above; provided, however, that Executive shall
                  not be prohibited by this Agreement from employing or
                  soliciting the employment of any employee that the Company
                  terminates after the date of such termination; and

                           (iv) make or publish any statement, written or oral,
                  disparaging the reputation of the Company or its
                  subsidiaries, executive officers or any of its business
                  services or products or solicit or encourage any member of
                  any prepaid dental plan of the Company or its subsidiaries or
                  any third party having a group agreement with the Company or
                  its subsidiaries to terminate the membership of such person
                  in the plan of the Company or its subsidiaries or to
                  terminate such group agreement.

                  (d) In its sole discretion, the Company shall have the right
         at any time and from time to time, evidenced solely by the written
         approval of the Board of Directors of the Company, to waive all or any
         portion of the rights of the Company under the covenants not to
         compete contained in this Agreement as applicable to Executive,
         including, without limitation, reducing the scope of covenant 



                                       4
<PAGE>   64



         not to compete applicable to Executive or reducing the time period or
         the geographical area of the covenant not to compete applicable to
         Executive; provided that as so amended by waiver such covenant not to
         compete shall remain fully in effect. In order to be effective, any
         such waiver must be in writing, approved by the Board of Directors of
         the Company as provided above, and executed by an authorized officer
         of the Company.

                  (e) Executive acknowledges and agrees that the provisions of
         this Agreement contain reasonable limitations as to time, geographical
         area and scope of activities to be restrained and do not impose a
         greater restraint than is necessary to protect goodwill and other
         business interests of the Company and its subsidiaries, (iii) if any
         portion of the covenants and agreements set forth in this Agreement
         are held to be invalid, unreasonable, arbitrary or against public
         policy, then such portion of such covenants shall be considered
         divisible as to time, scope of activities covered, and geographical
         area, (iv) if any court of competent jurisdiction determines the
         specified time period, scope of activities covered, or the specified
         geographical area applicable to any provision of this Agreement to be
         invalid, unreasonable, arbitrary or against public policy, a lesser
         time period, scope of activities covered, and/or geographical area
         which is determined to be reasonable, non-arbitrary and not against
         public policy may be enforced against Executive.

         11. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8, 9 and 10 of this Agreement shall continue to be
binding upon the Executive, notwithstanding the termination of his employment
with the Company for any reason whatsoever. Such covenants shall be deemed and
construed as separate agreements independent of any other provisions of this
Agreement and any other agreement between the Company and the Executive. The
existence of any claim or cause of action by the Executive against the Company,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of any or all of such covenants. It
is expressly agreed that the remedy at law for the breach of any such covenant
is inadequate and the injunctive relief shall be available to prevent to the
breach or any threatened breach thereof.

         12. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         thirty (30) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon thirty (30) days prior written notice to the Executive.

                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:



                                       5
<PAGE>   65

                           (1) If the Executive becomes disabled for a period
                  of more than ninety (90) consecutive days (for the purposes
                  hereof, "disabled" shall have the same meaning as is provided
                  for such term in the group long-term disability insurance
                  policy maintained by the Company on the Effective Date);

                           (2) If the Executive for reasons other than
                  vacation, illness or injury absents herself from his duties
                  without the consent of the Board for more than ten (10)
                  consecutive days;

                           (3) If the Executive should die (effective on the
                  date of death);

                           (4) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (5) If the Executive should willfully breach or,
                  after written notice from the Company, habitually neglect his
                  duties which he is required to perform under this Agreement
                  or otherwise fail to comply with the terms and conditions of
                  this Agreement specifically including, but not limited to,
                  the covenants set forth in Paragraphs 8, 9 and 10 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by his prior to the date of termination as provided herein
computed on a pro rata basis to and including such date of termination. In the
event the Company terminates this Agreement without cause pursuant to Paragraph
12(b) above, the Executive shall be entitled to receive a severance payment as
liquidated damages for, and in lieu of, any and all damages which he may incur
as a result of such termination in an amount equal to his base salary as
specified in Paragraph 5(a) as then in effect on the date of termination over
remaining term of this Agreement. Such severance payment shall be payable in
installments on the same dates that such payments would have been made during
the term of this Agreement. In addition, in such event, the Company shall
continue to pay for the group health and life insurance provided for the
Executive on the date of the termination until the end of the original term of
this Agreement. The Executive shall be entitled to no further compensation as
of the date of termination of this Agreement specifically including but not
limited to any unearned bonuses under this Agreement. Any termination of this
Agreement shall be without prejudice to any right or remedy to which the
terminating party may be entitled either at law, in equity, or under this
Agreement.

         13. Notices. Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to

         held to be illegal, invalid, or unenforceable under present or future
         laws effective during the term hereof, such provision shall be fully
         severable and this Agreement shall be construed and enforced as if
         such illegal, invalid, or unenforceable provision had never comprised
         a part hereof; and the remaining provisions hereof shall remain in
         full force and effect and shall not be affected by the illegal,

                         POST-CLOSING ESCROW AGREEMENT


         This Post-Closing Escrow Agreement (this "Agreement") is made as of
the _______ day of __________, 1996 (the "Effective Date") by and among United
Dental Care, Inc., a Delaware corporation ("Purchaser"), John E. Carlin, Ph.D.
("Carlin"), Frank J. Schloegel, III ("Schloegel") and J. Dennis Dlabal, D.D.S.
("Dlabal"), (collectively referred to herein as the "Individual Sellers" and
individually as an "Individual Seller"), and UMB Bank, N.A., escrow agent (the
"Escrow Agent").

         WHEREAS, Purchaser, the Individual Sellers, and Kansas City Dental
Care, Inc., a Missouri corporation (the "Company"), together with certain other
stockholders of the Company, entered into a Stock Purchase Agreement, dated as
of September ___, 1996 (the "Stock Purchase Agreement"), providing for the sale
of all of the issued and outstanding shares of capital stock of the Company to
Purchaser; and

         WHEREAS, pursuant to the Stock Purchase Agreement, the Individual
Sellers agreed to place the sum of Three Hundred Fifty Thousand Dollars
($350,000) of the Purchase Price paid to Individual Sellers in escrow for the
purposes hereinafter set forth upon the consummation of the transactions
contemplated by the Stock Purchase Agreement; and

         WHEREAS, the transactions contemplated by Stock Purchase Agreement
have been consummated on the date hereof and the parties desire to effectuate
the provisions of the Stock Purchase Agreement with respect to such
post-closing escrow fund;

         NOW, THEREFORE, in consideration of the premises and the mutual terms
and conditions of the Stock Purchase Agreement hereof, the parties hereby agree
as follows:

         1. Escrow Money. Simultaneously with the execution of this Agreement,
the Individual Sellers have deposited with the Escrow Agent the sum of Three
Hundred Fifty Thousand Dollars ($350,000) (the "Escrow Money") which
constitutes a portion of the purchase price paid to the Individual Sellers
pursuant to the Stock Purchase Agreement. Each Individual Seller has an equal
one-third (33.3%) interest in the Escrow Money. The receipt of the deposit of
the Escrow Money is hereby acknowledged by the Escrow Agent by its execution
hereof.

         2. Escrow Account. The Escrow Money shall be held in escrow by the
Escrow Agent pursuant to the terms and conditions of this Agreement. Upon
receipt of the Escrow Money, the Escrow Agent shall establish a separate escrow
account entitled "United Dental



                                       1
<PAGE>   74



Care/John E. Carlin, Ph.D./Frank J. Schloegel, III/J. Dennis Dlabal
Post-Closing Escrow Account" and shall deposit the Escrow Money into such
escrow account. The Escrow Agent shall invest monies held in the Escrow Account
in Scout Prime Money Market Fund, Scout Federal Money Market Fund, UMB Money
Market Special, treasury bills or other similar instruments directed in writing
by the Individual Sellers with a maturity date not in excess of ninety (90)
days under the social security numbers of Individual Sellers. It is understood
and agreed that the Escrow Agent will be issuing a 1099 INT Statement to each
Seller and the Internal Revenue Service. Individual Sellers shall have the
responsibility as to any 1099 INT reporting thereof. The Escrow Agent shall
invest the Escrow Money as the Individual Sellers direct pursuant to reasonable
investment instructions of Individual Sellers which in each case may be given
verbally and confirmed in writing and sent to the Escrow Agent no later than
the next business day. The Escrow Money shall at all times be held in a
separate escrow account and shall only be delivered pursuant to the terms and
conditions of this Agreement.

         3. Terms of Escrow. The Escrow Money shall be held in the Escrow
Account as a fund available to satisfy any obligations of Individual Sellers to
Purchaser which may arise under Section 11.2(a) of the Stock Purchase Agreement
in the manner set forth below:

                  (a) In the event that Purchaser shall assert a claim or
         claims against Individual Sellers arising out of or relating to any
         matter with respect to which Purchaser asserts that it is entitled to
         be indemnified by Individual Sellers pursuant to Section 11.2(a) of
         the Stock Purchase Agreement (collectively, the "Claims"; singularly a
         "Claim"), Purchaser shall furnish written notice of the Claim (the
         "Notice of Claim") to Individual Sellers and the Escrow Agent on or
         before the day preceding the second anniversary of the Effective Date
         (the "Release Date"). The Notice of Claim: (i) shall state in
         reasonable detail the nature of Individual Sellers' alleged liability;
         (ii) shall state the amount of the payment that Purchaser claims it is
         entitled to receive from the Escrow Money based upon Purchaser's
         estimate of the potential loss; and (iii) shall further provide a
         particularized statement explaining the basis for such estimate.
         Individual Sellers shall have thirty (30) days after receipt by the
         Escrow Agent of the Notice of Claim in which to advise the Escrow
         Agent and Purchaser that it disputes the Claim by delivering written
         notice of Individual Sellers' dispute ("the Notice of Dispute") to the
         Escrow Agent and Purchaser. The Notice of Dispute may contest all or
         any portion of the Notice of Claim based on a dispute concerning the
         existence of a Claim, Individual Sellers' liability, the estimated
         amount of the alleged loss or any other related matter.

                  (b) If Escrow Agent fails to receive a Notice of Dispute
         within such thirty (30) day period, Individual Sellers shall be deemed
         to have acknowledged that Purchaser is entitled to payment as set
         forth in the Notice of Claim and shall be deemed to have directed the
         Escrow Agent to disburse such payment (the "Claim Payment") to
         Purchaser. In the event a Notice of Dispute is timely received by the
         Escrow Agent, then the undisputed portion of the Claim, if any (the
         "Undisputed Claim Payment"), shall be promptly disbursed to Purchaser
         from the Escrow Account and only the sum that is subject to a dispute
         shall be held by the Escrow Agent until the Claim is resolved;
         provided, however, that any Claim which is based upon the assertion or
         threat of a third



                                       2
<PAGE>   75



         party claim against Purchaser shall be conclusively deemed to be
         resolved two (2) years after the Notice of Claim is delivered unless
         litigation, arbitration, assessment or some other formal proceeding is
         commenced against Purchaser by the Escrow Agent within that two (2)
         year period. If such a formal proceeding is not commenced within such
         two (2) year period, then the Claim shall be deemed abandoned and of
         no further force and effect for purposes of this Agreement. In the
         event a formal proceeding is commenced within the two (2) year period,
         then the resolution of the Claim will occur only upon the resolution
         of such proceeding and any related appellate proceedings.

                  (c) Subject to Individual Sellers' right to dispute a Claim,
         once a Notice of Claim is received by the Escrow Agent, the Escrow
         Agent shall not permit the Escrow Money to be reduced by disbursement
         to Individual Sellers to an amount which is less than the difference
         between the aggregate dollar amount of each Claim for which a Notice
         of Claim has been received by the Escrow Agent on or prior to the
         Release Date in accordance with the terms of Section 3(a) above less
         the amount of $25,000 (unless such claim is not subject to the
         Threshold limitation as specified in Section 11.4(a) of the Stock
         Purchase Agreement and such fact is so stated in the Notice of Claim).
         Furthermore, if the amount of any Claim or the aggregate amount of any
         Claims should ever exceed the sum of $25,000 plus the amount of the
         Escrow Money, then no portion of the Escrow Money shall be disbursed
         pursuant to Section 3(d) below, during such time that such a deficit
         exists.

                  (d) On the Release Date, the Escrow Agent shall
         unconditionally disburse to Individual Sellers the portion of the
         Escrow Money to the extent it exceeds the sum of: (i) the aggregate
         dollar amount of each Claim previously paid pursuant to the terms of
         this Agreement and the Stock Purchase Agreement; plus (ii) the
         aggregate dollar amount of any then existing Claim or Claims for which
         a Notice of Claim was delivered on or prior to the Release Date in
         accordance with the terms of Section 3(a) above less the amount of
         $25,000 (unless such claim is not subject to the Threshold limitation
         as specified in Section 11.4(a) of the Stock Purchase Agreement and
         such fact is so stated in the Notice of Claim). The remaining portion
         of the Escrow Money not distributed, if any, shall continue to be held
         pursuant to the terms of this Agreement and shall be unconditionally
         disbursed to Individual Sellers (or Purchaser, if appropriate), in one
         or more disbursements, from time to time, upon final resolution of all
         Claims involving such funds. Notwithstanding the foregoing, if the
         aggregate amount of the Adjustment Amount to be paid by the Purchaser
         pursuant to Section 2.3 of the Stock Purchase Agreement (which amount,
         when agreed upon, shall be certified in writing by the Purchaser to
         the Escrow Agent) is less than $350,000, then the Escrow Agent shall
         disburse any amount payable to the Individual Sellers under this
         Section 3(d) to George C. Kopp, III until the sum of the Adjustment
         Amount and the disbursements to George C. Kopp, III equal $350,000.
         George C. Kopp, III is an intended third party beneficiary of this
         Section 3(d) and shall be entitled to enforce the same against the
         Individual Sellers and the Escrow Agent as if he were a signatory
         hereto.



                                      3
<PAGE>   76



                  (e) Unless delivery is made in person at the Escrow Agent's
         office or unless the Escrow Agent is properly instructed in writing by
         Purchaser or Individual Sellers, as the case may be, to make delivery
         in such other manner, the Escrow Agent shall be deemed to have
         properly delivered to Purchaser or Individual Sellers, as the case may
         be, such funds as Purchaser or Individual Sellers are entitled to
         receive, upon placing a check or draft for such amount in United
         States Mail in a suitable package or envelope, registered or certified
         mail, return receipt requested, postage prepaid, addressed to the
         address listed in Section 7 hereof or such other address as may be
         furnished to the Escrow Agent in writing.

                  (f) Without any notice to or consent by Purchaser, interest,
         dividends, capital gains, distributions or other earnings on the
         Escrow Money shall be released to Individual Sellers by the Escrow
         Agent quarterly on a pro-rata basis pursuant to the instructions of
         Individual Sellers, both before and after the Release Date.

                  (g) Notwithstanding any other provision hereof which shall
         direct the release of all or a part of the Escrow Money on a
         particular date, without the prior written consent of Purchaser and
         Individual Sellers as to any withdrawal before the Release Date, and
         without the prior written consent of Individual Sellers as to any
         withdrawal on or after the Release Date, the Escrow Agent shall not
         withdraw any investment of the Escrow Money prior to the maturity date
         of such investment to make a payment to Purchaser or Individual
         Sellers hereunder if such withdrawal will cause an early withdrawal
         penalty to be imposed or any loss of principal from such withdrawal to
         occur. If such a penalty would be imposed or any loss of principal
         would occur if the investment were to be withdrawn, the payment of any
         amounts of the Escrow Money due to Individual Sellers or to Purchaser
         shall be made as soon as practicable after the maturity date of the
         investment.

         4. Liability of Escrow Agent. Individual Sellers and Purchaser agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and immunities of the Escrow Agent:

                  (a) The Escrow Agent is not a party to, and is not bound by,
         or charged with notice of, any agreement out of which this escrow may
         arise.

                  (b) The Escrow Agent acts hereunder as a depository only, and
         is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or depositing the escrow. The Escrow Agent shall not be
         liable for anything that it may do or refrain from doing in connection
         herewith, except its gross negligence or willful misconduct.

                  (c) The Escrow Agent shall be protected in acting upon any
         written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other



                                       4
<PAGE>   77



         paper or document which the Escrow Agent in good faith believes to be
         genuine and what it purports to be.

                  (d) Individual Sellers and Purchaser, jointly and severally,
         agree to indemnify and hold the Escrow Agent harmless against any and
         all losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non-performance
         of its duties hereunder, excluding, however, any such liability
         resulting from its gross negligence, willful misconduct or breach of
         its instructions under this Agreement. In the event the Escrow Agent
         becomes involved in litigation in connection with this escrow,
         Individual Sellers and Purchaser, jointly and severally, agree to
         indemnify and save the Escrow Agent harmless from any and all losses,
         claims, damages, liabilities and expenses, including attorney's fees
         and costs, which may be incurred or suffered by Escrow Agent as a
         result thereof, excluding, however, any such liability resulting from
         its gross negligence, willful misconduct, or breach of its
         instructions under this Agreement.

                  (e) In the event of any disagreement between any of the
         parties to this Agreement resulting in adverse claims or demands being
         made in connection with the Escrow Money, or in the event the Escrow
         Agent in good faith is in doubt as to what action it should take
         hereunder, the Escrow Agent may, at its option, refuse to comply with
         any claims or demands on it, or refuse to take any other action
         hereunder, so long as such disagreement continues or doubt exists, and
         in such event, the Escrow Agent shall not be or become liable in any
         way or to any person for its failure or refusal to act, and the Escrow
         Agent shall be entitled to continue to so refrain from acting until
         (i) the rights of all the parties shall have been fully and finally
         adjudicated by a court of competent jurisdiction, or (ii) all
         differences shall have been adjudicated and all doubt resolved by
         agreement among all the interested parties and the Escrow Agent shall
         have been notified thereof pursuant to written directions duly
         executed by all such persons.

                  (f) The Escrow Agent may consult with legal counsel in the
         event of any dispute or question as to the construction of any of the
         provisions hereof or its duties hereunder, and it shall incur no
         liability and shall be fully protected in acting in accordance with
         the opinion and instructions of such counsel.

         5. Compensation of Escrow Agent. The fees and expenses of the Escrow
Agent in connection with this Agreement shall be paid by Purchaser. The
acceptance and routine maintenance fee for the Escrow Agent in connection with
this Agreement shall be Two Thousand Two Hundred Dollars ($2,200.00); provided,
however, that such fee is acknowledged to represent the fee for expected
minimum routine services and expenses for the expected duration of the escrow
(i.e. assumes no more than three disbursements by wire transfer, ten investment
purchases of Treasury Bills or commercial paper, quarterly disbursement of
income to the three Individual Sellers and termination on or before the
twenty-eighth month of the escrow) and does not include services and expenses
in connection with disputes, extensions or other additional services.
Additional services will be charged and payable at the rates in force for the
Corporate



                                       5

Trust Division of the Escrow Agent at the time such services are provided, plus
reimbursement for any out-of-pocket expenses incurred. The employment of
outside counsel or agents is not anticipated and the above fees and expenses
include no fees or expenses for such employment.

         6. Non-Waiver. Nothing contained in this Agreement shall be deemed or
construed to release or waive any of the rights or obligations of Purchaser or
Individual Sellers under the Stock Purchase Agreement, and all rights and
remedies of Individual Sellers and Purchaser under this Agreement are
cumulative of all other rights which either of them may have under the Stock
Purchase Agreement, by law or otherwise.

         7. Notices. Any notices, claims or demands which any party is required
or may desire to give to another under or in conjunction with this Agreement
shall be in writing, and shall be given by addressing the same to such other

understanding of the parties and supersedes all prior agreements or
understandings, whether

written or oral, with respect to the subject matter hereof. No terms,
conditions or agreements other than those contained herein, and no amendments
or modifications hereto shall be valid unless made in writing and signed by the
parties hereto.

         9. Capitalized Terms. Capitalized terms in this Agreement which are
not otherwise defined herein shall have the same meanings as are provided for
such terms in the Stock Purchase Agreement.

         10. Binding Effect. This Agreement shall extend to and be binding upon
and inure to the benefit of the parties hereto, their respective successors and
assigns.

         11. Waiver; Remedies. Waiver by any party hereto of any breach of or
exercise of any rights under this Agreement shall not be deemed to be a waiver
of similar or other breaches or rights or a future breach of the same duty. The
failure of a party to take any action by reason of any such breach or to
exercise any such right shall not deprive any party of the right to take any
action at any time while such breach or condition giving rise to such right
continues. The parties shall have all remedies permitted to them by this
Agreement or law, and all such remedies shall be cumulative.

         12. Termination. This Agreement shall terminate at such time as all of
the Escrow Money shall have been released in accordance with the terms and
conditions of this Agreement.

         13. Notification. Escrow Agent by Escrow Agent's execution
acknowledges that Escrow Agent has received notification of Purchaser's
interest in the Escrow Money.

         14. Resignation and Termination. The Escrow Agent may resign as such

Upon expiration of such sixty (60) day notice period, the Escrow Agent may
deliver the portion of the Escrow Money remaining in its possession to any
successor Escrow Agent appointed by Individual Sellers and Purchaser pursuant
to this Section 14 or, if no successor Escrow Agent has been appointed, to any
court of competent jurisdiction in Jackson County, Missouri, or in accordance
with the joint written instructions of Purchaser and Individual Sellers.
Purchaser and Individual Sellers, acting jointly, may terminate the Escrow
Agent from its position as such by delivering to the Escrow Agent written
notice to that effect executed by Purchaser and Individual Sellers at least
thirty (30) days prior to the effective date of such termination. In the event
of such resignation or termination of the Escrow Agent, a successor Escrow
Agent shall be appointed by mutual agreement between Purchaser and Individual
Sellers, and the Escrow Agent shall deliver the portion of the Escrow Money
remaining in its possession to such successor Escrow Agent. From and after the
appointment of a successor Escrow Agent pursuant to this Section 14, the rights
and duties of the Escrow Agent hereunder shall cease and terminate, and all
references herein to the Escrow Agent shall be deemed to be to such successor
Escrow Agent. The delivery by the Escrow Agent of the Escrow Money hereunder in
accordance with the provisions of this Section 14 shall constitute a full and
sufficient discharge and acquittance of the Escrow Agent in respect to such
sums delivered, and the Escrow Agent shall be entitled to receive releases and
discharges



                                       7

therefor. The indemnities in favor of the Escrow Agent contained in this
Agreement and the obligations of Purchaser and Individual Sellers under Section
4 hereof shall survive for the benefit of the Escrow Agent after any
resignation or termination.

         15. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

         16. Security Interests. No party to this Agreement shall grant a
security interest in any monies or other property deposited with the Escrow
Agent under this Agreement, or otherwise create a lien, encumbrance or other
claim against such monies or borrow against the same."

                         EARNEST MONEY ESCROW AGREEMENT


         This Earnest Money Escrow Agreement (this "Agreement") is made as of
the 11 day of September, 1996 (the "Effective Date") by and among United Dental
Care, Inc., a Delaware corporation ("Purchaser"), John E. Carlin, Ph.D.
("Carlin"), Frank J. Schloegel, III ("Schloegel"), J. Dennis Dlabal, D.D.S.
("Dlabal", and together with Carlin and Schloegel, the "Individual Sellers"),
The John E. Carlin Charitable Remainder Unitrust, UID June 28, 1996, the Frank
J.  Schloegel Charitable Remainder Unitrust I, UID July 12, 1996, and the Frank
J. Schloegel Charitable Remainder Unitrust II, UID July 12, 1996, and The J.
Dennis Dlabal Charitable Remainder Trust, UID September 5, 1996 (collectively
referred to herein as the "Sellers" and individually as a "Seller"), and UMB
Bank, N.A., escrow agent (the "Escrow Agent").

         WHEREAS, Sellers and Purchaser have entered into that certain Stock
Purchase Agreement dated September 11, 1996 (the "Stock Purchase Agreement")
providing for the purchase of all the issued and outstanding shares (the
"Shares") of capital stock of Kansas City Dental Care, Inc., a Missouri
corporation (the "Company"), from the Sellers by Purchaser; and

         WHEREAS, in connection with the execution of the Stock Purchase
Agreement, Purchaser agreed to place the sum of Two Hundred Thousand and
no/100ths Dollars ($200,000) in escrow for the purposes hereinafter set forth.
(Such escrow deposit and any interest earned thereon while such funds are in
escrow are referred to herein as the "Escrow Money"); and

         WHEREAS, the parties desire to effectuate the provisions of the Stock
Purchase Agreement with respect to the Escrow Money;

         NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the mutual terms
and conditions hereof, the parties hereby agree as follows:

         1.      Escrow Money.  Simultaneously with the execution of this
Agreement, Purchaser has deposited the sum of $200,000 with the Escrow Agent,
the receipt of which is hereby acknowledged by the Escrow Agent by its
execution hereof.

         2.      Escrow Account.  The Escrow Money shall be held in escrow by
the Escrow Agent pursuant to the terms and conditions of this Agreement.  Upon
receipt of the Escrow Money, the Escrow Agent shall establish a separate escrow
account entitled "United Dental Care and Kansas City Dental Care Earnest Money
Escrow Account" and shall deposit the Escrow Money therein and shall report any
income thereon under the federal tax identification (ID)




                                      1

number of the Purchaser (#75-2309712) as certified by the Purchaser in a Form
W-9 executed and delivered to the Escrow Agent simultaneously with the
execution of this Agreement.  It is understood and agreed that the Escrow Agent
will be issuing a 1099 INT statement to the Purchaser and the Internal Revenue
Service, even though the interest may be payable eventually to either the
Purchaser or the Sellers as the case may be.  The Purchaser shall have the
responsibility as to any 1099 INT reporting thereof.  The Escrow Agent may
invest the Escrow Money in UMB Money Market Special, Scout Prime Money Market
Fund or Scout Federal Money Mutual Fund as the Purchaser may direct pursuant to
reasonable investment instructions of Purchaser which in each case may be given
verbally and confirmed in writing and sent to the Escrow Agent no later than
the next business day.  The Escrow Money shall at all times be held in a
separate escrow account and shall only be delivered pursuant to the terms and
conditions of this Agreement.

         3.      Terms of Escrow.  The Escrow Money shall be held as a trust
deposit and shall be applied by the Escrow Agent in accordance with the
following terms and directions:

                 (a)      Application upon Closing.  In the event that the
         Sellers have not furnished written notice to Purchaser and the Escrow
         Agent of the failure of Purchaser to consummate the Stock Purchase
         Agreement in accordance with Section 3(b) below prior to Closing under
         the Stock Purchase Agreement, then, upon the Closing, Escrow Agent
         shall receive a notice executed by Purchaser and Sellers directing
         Escrow Agent to either (i) pay the Escrow Money to Sellers as the
         notice shall direct in which case the $200,000 escrow deposit and any
         interest earned thereon shall constitute a credit against the Purchase
         Price or (ii) refund the Escrow Money to the Purchaser in which case
         it shall not constitute a credit against the Purchase Price.

                 (b)      Application upon Termination.  If Purchaser fails to
         consummate the Stock Purchase Agreement for any reason other than (i)
         a material breach of the Stock Purchase Agreement or this Agreement by
         Sellers or (ii) the valid exercise of any right of termination by
         Purchaser expressly set forth in the Stock Purchase Agreement, then
         the Sellers shall furnish written notice to Purchaser and the Escrow
         Agent of Purchaser's failure to consummate the Stock Purchase
         Agreement and directing that the Escrow Money be paid to the Sellers.
         Ten (10) days after such notice is received by Purchaser and the
         Escrow Agent as proven by cancellation marks on registered or
         certified mail return receipts, the Sellers shall be entitled to be
         paid the Escrow Money on pro rata basis determined according to the
         percentage of the Purchase Price under the Stock Purchase Agreement
         (which amounts shall be certified in writing to the Escrow Agent by
         the Sellers) that would have been payable to the Sellers and the
         Escrow Agent shall release the Escrow Money to the Sellers on such pro
         rata basis.  Otherwise, ten (10) days after receipt of written
         notice/demand from the Purchaser to the Sellers and the Escrow Agent
         that one of the conditions stated in (i) or (ii) above has occurred
         and that the Purchaser is entitled to receive a refund of the Escrow
         Money, as proven by cancellation marks on registered or certified mail
         return receipts, the Purchaser shall be entitled to be refunded the
         Escrow Money and the Escrow Agent shall release the Escrow Money to
         the Purchaser.

<PAGE>   3
                 (c)      Automatic Termination.  In the event that the Escrow
         Agent has not received instructions as to the release of the Escrow
         Money before March 11, 1997, then this Escrow Agreement shall
         automatically terminate on March 11, 1997 and the Escrow Agent shall
         refund the Escrow Money to Purchaser without the necessity of any
         further notice or instructions of any kind.
        
                 (d)      Interest.  Interest earned on the Escrow Money shall
         be deemed a part of and applied together with the Escrow Money and
         paid to the Sellers or to Purchaser as the case may be as specified
         above.

         4.      Liability of Escrow Agent.  Purchaser and Sellers hereby agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and immunities of the Escrow Agent:

                 (a)      The Escrow Agent is not a party to, and is not bound
         by, or charged with notice of, any agreement out of which this escrow
         may arise.

                 (b)      The Escrow Agent acts hereunder as a depository only,
         and is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or deposition the escrow.  The Escrow Agent shall not be
         liable for anything that it may do or refrain from doing in connection
         herewith, except its gross negligence or willful misconduct.

                 (c)      The Escrow Agent shall be protected in acting upon
         any written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other paper or document which the
         Escrow Agent in good faith believes to be genuine and what it purports
         to be.

                 (d)      Purchaser and the Sellers, jointly and severally,
         agree to indemnify and hold the Escrow Agent harmless against any and
         all losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non- performance
         of its duties hereunder whether such losses, claims, demands,
         liabilities and expenses arise during or subsequent to performance of
         this Agreement, directly or indirectly, excluding, however, any such
         liability resulting from its gross negligence, willful misconduct, or
         breach of its instructions under this Agreement.  In the event the
         Escrow Agent becomes involved in litigation in connection with this
         escrow, Purchaser and the Sellers, jointly and severally, agree to
         indemnify and save the Escrow Agent harmless from any and all losses,
         claims, damages, liabilities and expenses, including attorney's fees
         and costs, interpleader costs and judgments, which may be incurred or
         suffered by Escrow Agent as a result thereof, excluding, however, any
         such liability resulting from its gross negligence, willful
         misconduct, or breach of its instructions under this Agreement.





                                      3
<PAGE>   4
                 (e)      In the event of any disagreement between any of the
         parties to this Agreement or with any third person resulting in
         adverse claims or demands being made in connection with the Escrow
         Money, or in the event the Escrow Agent in good faith is in doubt as 
         to what action it should take hereunder, the Escrow Agent may, 
         at its option, refuse to comply with any claims or demands on it, or
         refuse to take any other action hereunder, so long as such
         disagreement continues or doubt exists, and in such event, the Escrow
         Agent shall not be or become liable in any way or to any person for
         its failure or refusal to act, and the Escrow Agent shall be entitled
         to continue to so refrain from acting until (i) the rights of all the
         parties shall have been fully and finally adjudicated by a court of
         competent jurisdiction, or (ii) all differences shall have adjusted
         and all doubt resolved by agreement among all the interested parties
         and the Escrow Agent shall have been notified thereof pursuant to
         written directions duly executed by all such persons.  In the event of
         conflicting demands on the Escrow Agent by the principals, the Escrow
         Agent may, at its option, deposit any and all funds in question with
         the court that would have jurisdiction over the matter, and in such
         event, the Escrow Agent is relieved of any further responsibility in
         connection with this escrow.
        
                 (f)      The Escrow Agent may consult with legal
         counsel in the event of any dispute or question as to the construction
         of any of the provisions hereof or its duties hereunder, and it shall
         incur no liability and shall be fully protected in acting in
         accordance with the opinion and instructions of such counsel.

         5.      Compensation of Escrow Agent.  All fees and expenses of the
Escrow Agent shall be paid equally by the Sellers and the Purchaser.  The
acceptance and routine maintenance fee for the Escrow Agent in connection with
this Agreement shall be Eight Hundred Fifty and no/100ths Dollars ($850.00);
provided, however, that such fee is acknowledged to represent the fee for
expected minimum routine services and expenses for the expected six (6) month
duration of the escrow and does not include services and expenses in connection
with disputes, extensions or other additional services.  Additional services
will be charged and payable at the rates in force for the Corporate Trust
Division of the Escrow Agent at the time such services are provided, plus
reimbursement for any out-of-pocket expenses incurred.  The employment of
outside counsel or agents is not anticipated and the above fees and expenses
include no fees or expenses for such employment.

         6.      Non-Waiver.  Nothing contained in this Agreement shall be
deemed or construed to release or waive any of the rights or obligations of
Purchaser or Sellers under the Stock Purchase Agreement, all rights and
remedies of Purchaser and Sellers under this Agreement are cumulative of all
other rights which either of them may have under the Stock Purchase Agreement,
by law or otherwise.

         7.      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this

governed by the internal laws, and not the law of conflicts, of the State of
Missouri.

         16.     Counterparts.  This Agreement may be executed in two or more

such by delivering written notice to that effect at least sixty (60) days prior
to the effective date of such resignation to Individual Sellers and Purchaser.
Upon expiration of such sixty (60) day notice period, the Escrow Agent may
deliver the portion of the Escrow Money remaining in its possession to any
successor Escrow Agent appointed by Individual Sellers and Purchaser pursuant
to this Section 17 or, if no successor Escrow Agent has been appointed, to any
court of competent jurisdiction in Jackson County, Missouri, or in accordance
with the joint written instructions of Purchaser and Individual Sellers.
Purchaser and Individual Sellers, acting jointly, may terminate the Escrow
Agent from its position as such by delivering to the Escrow Agent written
notice to that effect executed by Purchaser and Individual Sellers at least
thirty (30) days prior to the effective date of such termination.  In the event
of such resignation or termination of the Escrow Agent, a successor Escrow
Agent shall be appointed by mutual agreement between Purchaser and Individual
Sellers, and the Escrow Agent shall deliver the portion of the Escrow Money
remaining in its possession to such successor Escrow Agent.  From and after the
appointment of a successor Escrow Agent pursuant to this Section 17, the rights
and duties of the Escrow Agent hereunder shall cease and terminate, and all
references herein to the Escrow Agent shall be deemed to be to such successor
Escrow Agent.  The delivery by the Escrow

be entitled to receive releases and discharges therefor.  The indemnities in
favor of the Escrow Agent contained in this Agreement and the obligations of
Purchaser and Individual Sellers under Section 4 hereof shall survive for the
benefit of the Escrow Agent after any resignation or termination.

         18.     Security Interests.  No party to this Agreement shall grant a
security interest in any monies or other property deposited with the Escrow
Agent under this Agreement, or otherwise create a lien, encumbrance or other
claim against such monies or borrow against the same.

                 (vi)     each Note shall contain such other usual and

       2.3       Additional Payments.  Subject to the terms and conditions of

                 (a)      On or before March 31, 1998, the Purchaser shall pay
to the Sellers an amount equal to the product of five (5) times the Combined
Earnings of the Company (as defined in Exhibit B) for the calendar year ended
December 31, 1997, in excess of $3,478,000; provided, however, that such
payment shall be limited to and not exceed a maximum payment of $4,000,000.

                 (b)      On or before March 31, 1999, the Purchaser shall pay
to the Sellers an amount equal to the product of four (4) times the Combined
Earnings of the Company for the





                                       3
<PAGE>   11
calendar year ended December 31, 1998 in excess of the greater of $3,478,000 or
the actual Combined Earnings of the Company for the calendar year ended
December 31, 1997; provided, however, that such payment shall be limited to and
not exceed a maximum payment equal to the lesser of either $4,000,000 or an
amount equal to $6,000,000 less the Additional Payment made with respect to the
Combined Earnings of the Company for the 1997 calendar year under Section
2.3(a) above.  In no event shall the total of the Additional Payments with
respect to the Combined Earnings for both the 1997 and 1998 calendar years
exceed $6,000,000 in the aggregate.

                 (c)      With each Additional Payment, the Purchaser shall
deliver to the Sellers a statement (the "Combined Earnings Statement") setting
forth the Combined Earnings of the Company for the respective calendar year to
which the Additional Payment relates.  The Combined Earnings Statement shall be
calculated and prepared in accordance with the definitions, principles and
procedures set forth in Exhibit B.

                 (d)      Within thirty (30) business days after delivery of
the Combined Earnings Statement by Purchaser, Sellers may deliver written
notice (the "Protest Notice") to Purchaser of any objections, and the basis
therefor, which the Sellers may have to the Combined Earnings Statement.  The
failure of Sellers to deliver such Protest Notice within the prescribed time
period will constitute the acceptance of the Combined Earnings Statement as
delivered by Purchaser to the Sellers, unless such acceptance is induced by
fraud of the Purchaser.  Upon request, Purchaser shall provide to Sellers all
information reasonably necessary to explain and support the calculations
performed by Purchaser in the Combined Earnings Statement (including, without
limitation, all its work and other papers relative to the preparation of such
Combined Earnings Statement).  Sellers shall also have the right at their
expense to audit the records of the Company upon which such Combined Earnings
Statement was based during normal business hours at the premises of the Company
and to conduct interviews of employees with knowledge of such matters at the
Company premises in the presence of a representative of Purchaser.  During the
thirty (30) days following receipt of a Protest Notice by Purchaser, Purchaser
and Sellers shall attempt to resolve any disagreement with respect to the
Combined Earnings Statement.  If, at the end of such thirty (30) day period,
Purchaser and Sellers shall have failed to resolve the disagreement specified
in the Protest Notice, the items in dispute shall be referred to an accounting
firm of national reputation as may be agreed to by the parties (the
"Arbitrator") for final determination on an expedited basis, but not exceeding
forty-five (45) days.  This provision for arbitration shall be specifically
enforceable by the parties and the determination of the Arbitrator in
accordance with the provisions hereof shall be final and binding upon Purchaser
and Sellers with no right of appeal therefrom, other than as permitted under
applicable statutory or common law regarding the appealability of arbitration.
No court shall have jurisdiction over this dispute, other than to (i) enforce
the appointment of an arbitrator should the parties be unable to agree, (ii)
resolve disputes concerning the exchange or access to information under this
provision arising prior to the appointment of an arbitrator (the filing of such
an action shall toll the deadlines set forth herein) and (iii) confirmation of
any arbitration award.  The fees and expenses of the Arbitrator shall be paid
by the party whose last proposed offer for settlement of the items in dispute,
taken as a whole, was farther away from the final determination of the
Arbitrator.  Purchaser and Sellers agree that within five (5) days after the





                                       4
<PAGE>   12
final determination of the Combined Earnings Statement and the Additional
Payment as provided in this Section 2.3, the Purchaser shall pay any
underpayment to Sellers, or Sellers shall refund any overpayment to Purchaser,
as the case may be.

       2.4       Allocation of Purchase Price.  Purchase Price and the
Additional Payments shall be allocated and payable to each Seller in accordance
with the respective percentage of the Shares owned by each Seller as shown on
Exhibit A.

       2.5       Earnest Money.  Simultaneously with the execution and delivery
of this Agreement, Purchaser shall deposit the sum of Three Hundred Thousand
Dollars ($300,000.00) as earnest money (the "Earnest Money") with Prudential
Securities (the "Escrow Agent") to be held in trust pursuant to the terms and
conditions of that certain Earnest Money Escrow Agreement, a copy of which is
attached hereto as Exhibit C (the "Escrow Agreement").  The Escrow Agreement
shall be executed and delivered by the parties thereto simultaneously with the
execution and delivery of this Agreement.  It is expressly agreed that the
Earnest Money shall be applied strictly in accordance with the terms of the
Escrow Agreement.

       2.6       Covenants During Earn-Out.  Purchaser and the Company agree
that, until December 31, 1998, the Purchaser and the Company shall not:

                 (i)      divert to any significant extent the attention of or
       use the efforts of, any of the officers or key employees of the Company
       (including Ronald Mazzone) to or for matters unrelated to the Company;
       or

                 (ii)     use to any significant extent the assets, offices,
       facilities or personnel of the Company for matters unrelated to the
       Company.

stock, no options, warrants, or other rights, agreements, or commitments

4.5.  There are no pending or, to the knowledge of the Sellers, threatened
legal, administrative, arbitration or other actions, notices, or proceedings
nor any pending or, to the knowledge of the Sellers, threatened governmental
investigations by any federal, state or local government or any subdivision
thereof or by any public or private group which assert or allege any violation
of or non-compliance with any governmental requirements or which would have the
effect of limiting, prohibiting or changing the business operations of the
Company as authorized by the authorizations, certificates of authority,

governmental agencies required for the conduct of its respective business.

decrees or injunctions of any court, governmental department, commission,
agency or instrumentality by which the Company is bound or to which the Company
is subject.  The Company has not entered into or is subject to any judgment,
consent decree, compliance order or administrative order with respect to any
insurance or other similar law or received any request for information, notice,

has not received any notice of alleged violations thereof.

       4.6       Financial Statements.  The Company has delivered to Purchaser
a copy of (i) the unaudited combined financial statements of the Company (and
Oracare DPO, Oracare PA, Oracare Investors and Oracare Dental Labs, Inc.) as of
December 31, 1993 and the audited combined financial statements of the Company
and the other entities collectively included in such financial statements with
the Company as of December 31, 1994 and 1995 consisting in each case of a
combined balance sheet at each such respective date, and the related combined
statements of income, changes in stockholders' deficiency and cash flows for
the applicable twelve (12) month period then ended; (ii) unaudited combined
financial statements of the Company as of June 30, 1996 (the "Balance Sheet
Date") consisting of a combined balance sheet at such date (the "Company
Balance Sheet") and the related combined statements of income, changes in
stockholders' equity and cash flows for the applicable month and year-to-date
period then ended; (iii) unaudited financial statements of the Company as of
December 31, 1993, 1994 and 1995 consisting in each case of a balance sheet at
each such respective date and the related statements of income, changes in
stockholder's equity and cash flows for the applicable twelve (12) month period
then ended; and (iv) unaudited financial statements of the Company as of June
30, 1996 consisting of a balance sheet at such date and the related statements
of income changes in stockholder's equity and cash flows for the applicable
month and year-to-date period then ended.  Complete and accurate copies of all
such financial statements (the "Financial Statements") have been delivered to
Purchaser.  The combined Financial Statements include the assets and results of
operations of all businesses engaged in the dental benefits industry in which
the Sellers individually or in the aggregate own any interest except solely for
the business conducted as an individual licensed professional dental provider
personally rendering dental services.

       The Financial Statements present fairly in all material respects the
combined financial position of the Company and the other entities collectively
included in such combined financial statements with the Company, and the
combined results of the operations, changes in stockholders' equity and cash
flows of the Company and the other entities collectively included in such
financial statements with the Company, as of the respective dates thereof and
for the





                                       8
<PAGE>   16
respective periods covered thereby, in conformity with generally accepted
accounting principles ("GAAP").  Except as set forth in the Company Balance
Sheet included in the Financial Statements, as of the Balance Sheet Date there
were no liabilities, debts, claims or obligations, whether accrued, absolute,
contingent or otherwise, whether due or to become due, which are required by
GAAP to be set forth in a combined balance sheet of the Company and the other
entities collectively included in such financial statements with the Company
which have not been so set forth in the Company Balance Sheet.  The Financial
Statements were prepared from the books and records of the Company and the
other entities collectively included in such financial statements with the
Company.  There are no assets shown on the Company Balance Sheet which are
valued thereon at an amount materially in excess of their fair value as of the
Balance Sheet Date.  At the Balance Sheet Date, the Company or the other
entities (other than Oracare Investors) included therein owned each of the
assets included in the Company Balance Sheet.  From the date hereof through the
Closing Date, the Company will continue to prepare monthly and year-to-date
unaudited financial statements on the same basis and will promptly deliver the
same to Purchaser.  The foregoing representations will be applicable to all
such monthly unaudited financial statements so prepared and delivered;
provided, however, that such unaudited financial statements shall be subject to
normal year-end adjustments, none of which will be material.

       4.7       No Adverse Change.  Except as otherwise expressly contemplated
by this Agreement, since the Balance Sheet Date, the business of the Company
has been conducted only in the ordinary course and there has not been (i) any
material adverse change in the financial condition, business, properties,
assets, or results of operations of the Company (financial or otherwise)
exclusive of any general economic factors affecting the prepaid dental plan
industry in general; (ii) any material loss or damage (whether or not covered
by insurance) to any of the assets of the Company which materially affects or
impairs the ability of the Company to conduct its business as previously
conducted or any other event or condition of any character which has materially
and adversely affected the business or operations of the Company; (iii) the
attaching, placing or granting of, or the agreement to attach, place or grant,
any encumbrance on any of the assets of the Company; (iv) any sale or transfer
of any material portion of the assets of the Company; (v) any material changes
in the terms of any material contract of the Company; (vi) any material change
in the accounting systems, policies or practices of the Company; (vii) any
waiver by or on behalf of the Company of any rights which have any material
value; (viii) no taking under condemnation or right of eminent domain of any of
the assets of the Company; (ix) any entry into or termination of any material
commitment, contract, agreement, or transaction (including, without limitation,
any material borrowing or capital expenditure or sale or other disposition of
any material assets) by the Company; (x) any redemption, repurchase, or other
acquisition of any of its capital stock by the Company, or any issuance of
capital stock of the Company or of securities convertible into or rights to
acquire any such capital stock; (xi) any dividend or distribution declared, set
aside or paid on capital stock of the Company; (xii) any transfer or right
granted by the Company of or under any material lease, license, agreement,
patent, trademark, trade name, service mark or copyright; (xiii) any sale or
other disposition of any material asset of the Company, or any mortgage,
pledge, or imposition of any lien or other encumbrance on any material asset of
the Company, or any agreement relating to or contemplating any of the foregoing
not in the ordinary and usual course of business; (xiv) any





                                       9
<PAGE>   17
default or breach by the Company in any material respect under any contract,
license, or permit; or (xv) any material increase in the statutory reserves
required to be maintained by the Company.  Except as set forth on Schedule 4.7,
since the Balance Sheet Date, the Company has conducted its business only in
the ordinary and usual course of business and, without limiting the foregoing,
no changes have been made in (i) employee compensation levels other than usual
and customary annual adjustments, (ii) the manner in which employees of the
Company are compensated, (iii) supplemental benefits provided to any employees,
or (iv) the employment of any employees of the Company.

       4.8       No Undisclosed Liabilities.  True and correct copies of all
notes, agreements or other documents evidencing the outstanding debt of the
Company, as amended to and in effect on the Effective Date, have been delivered
to Purchaser by the Company.  The Company has no liabilities which are not
adequately reflected or reserved against on the face of the Company Balance
Sheet, except liabilities incurred since the Balance Sheet Date in the ordinary
course of business consistent with past practice which, in the aggregate, would
not have a material adverse effect on the condition (financial or otherwise),
assets or business of the Company.  Schedule 4.8 hereto sets forth each
liability of the Company in an amount in excess of $10,000 and each person to
whom the aggregate amount of liabilities owed to such person by the Company

valid, effective and continuing leasehold rights in the case of leased
property, to all of the assets reflected on the Company Balance Sheet and all
personal property owned or leased by it or used by it in the conduct of its
business in such a manner as to create the appearance or reasonable expectation
that the same is owned or leased by it, free and clear of all liens, security
interests, restrictions, claims, encumbrances, and charges except as disclosed
in Schedule 4.9.  The Sellers do not know of any potential action or assertion
of rights, including condemnation, by any party, governmental or other, and no
proceedings with respect thereto have been instituted of which any Seller or
the Company has notice, that would materially affect the ability of the Company
to utilize each of such assets in its business.  The Company has not received
any notices of default or other violations from any mortgagee regarding any
properties leased by the Company which defaults or violations have not been
cured prior to the Effective Date.  Schedule 4.9 hereto also contains a copy of
the asset depreciation schedules of the Company.  The assets now owned by the
Company constitute all assets reasonably necessary to enable Purchaser to
conduct the business and operations of the Company on substantially the same
terms as such business has been conducted historically.  Except as disclosed in
Schedule 4.9, all such assets are well maintained and in good operating
condition, except for normal wear and tear.

arbitration or other proceeding (including proceedings concerning labor
disputes or grievances or union recognition) pending or, to the knowledge of

in compliance with any applicable zoning, environmental or health laws and
regulations or any other similar law, statute, regulation or ordinance.  The
Company is the lessee and in peaceful and undisturbed possession of the
property subject to the Real Property Leases.  To the knowledge of the Sellers,
all covenants or other restrictions (if any) to which any of the property
leased to the Company pursuant to the Real Property Leases are being properly
performed and observed in all material respects by the Company, and the Company
has not received any notice of violation (or claimed violation) thereof which
has not been resolved.  The Company has delivered to Purchaser true, correct
and complete copies of all reports or audits of any engineers, environmental
consultants or other consultants in its possession relating to any of the Real

threatened proceeding or governmental action to condemn or take by the power of
eminent domain (or to purchase in lieu thereof) all or any part of the property
subject to the Real Property Leases which is material to the operations of the
Company as presently conducted.  The Company does not own any real property.

       4.12      Intellectual Property.  Schedule 4.12 is an accurate and
complete list of all tradenames that the Company uses in its business
operations.  Such tradenames are owned by Frank A. Pettisani, D.D.S. and
licensed by him to the Company for its use.  Except as reflected on Schedule
4.12, the Company has no United States and foreign patents, patent
applications, patent licenses, trademarks, and service mark registrations (and
applications therefor), and has no copyrights and copyright registrations (and
applications therefor), trade secrets, inventions, processes, designs, know-
how and formula which are owned or licensed for use by the Company and utilized
by the Company in the business or operations of the Company as presently
conducted.  There is no adverse claim against the Company, or to the knowledge
of the Sellers, any threatened litigation or claim of infringement.  Except as
set forth on Schedule 4.12, to the knowledge of the Sellers, the Company does
not utilize any intellectual or proprietary trade secret information which
infringes any trademark, tradename, service mark, copyright or patent of
another, and the Company has not received any notice contesting its right to
use any trade name now used by it in connection with its business or the
operation thereof.  The Company has not granted any license to a third party in

                                       23
<PAGE>   31
Agreement by the Company, the Company will promptly provide such other

including, without limitation, insurance regulatory authorities in any
jurisdiction in which the Company conducts business, as such regulatory
authorities or Purchaser may reasonably request.  Between the date hereof and
the Closing Date, the Company shall promptly provide Purchaser with copies of
all correspondence and filings to or from all governmental and regulatory
bodies and officials relating to the Company.

       6.7       Publicity.  Prior to the Closing, any public statement or
announcement by the Sellers or Company, including but not limited to any
written news releases, pertaining to this Agreement or the transactions
contemplated thereby shall be submitted to Purchaser for review and approval
prior to the release by the Company, and shall be released only in a form
approved by Purchaser, provided, however, that (i) such approval shall not be
unreasonably withheld and (ii) such review and approval shall not be required
of statements and announcements if prior review and approval would prevent the
timely and accurate dissemination of such statements and announcements as
required to comply, in the judgement of counsel, with any applicable law, rule
or policy.  Sellers and Purchaser shall issue a press release regarding the
execution of this Agreement within one day of the date hereof or such other
time as Sellers and Purchaser may mutually agree.

       6.8       Financial Information.  Sellers will cause the Company to, and

unaudited financial statements of the Company for each month from and after the

course of business.

       6.9       Expenses.  The Company may pay prior to or at Closing the fees
and expenses of Counsel to Sellers and other advisors or financial consultants
to the Sellers incurred in connection with this Agreement and the consummation
of the transactions contemplated hereby; provided, however, that such costs and
expenses shall be included in determining the Net Income of the Company for the

incurred by Sellers in connection with this Agreement after the Closing.

       6.10      Breach of Representations and Warranties.  Promptly upon any
Seller or the Company becoming aware of any breach of any of the
representations and warranties of the Sellers contained in this Agreement, or
any event which would cause the Sellers to be unable to deliver the
certificates contemplated by Section 9.1(e) hereof, the Sellers shall give
written notice thereof to the Purchaser in sufficient detail to permit the
Purchaser to ascertain the nature of the breach and shall use all commercially
reasonable efforts to prevent or promptly remedy the same.

terminated, each Seller shall not, directly or indirectly, exchange, transfer,

<PAGE>   32
       6.12      Updating of Exhibits and Schedules.  Sellers shall notify
Purchaser in writing of any changes, additions, or events which may cause any
change in or addition to the Schedules delivered by them under this Agreement
promptly after the occurrence of the same and again at the Closing by delivery
of appropriate updates to all such Schedules.  No notification of a change or
addition to a Schedule made pursuant to this Section shall be deemed to cure
any breach of any representation or warranty resulting from such change or
addition unless Purchaser specifically agrees thereto in writing, nor shall any
such notification be considered to constitute or give rise to a waiver by
Purchaser of any condition set forth in this Agreement; provided, however,
that, in the event Purchaser has actual knowledge of any uncured
misrepresentation or breach of warranty at or prior to the Closing and
nevertheless proceeds with the Closing, then the Purchaser shall be deemed to
have waived such misrepresentation or breach of warranty.  Nothing contained
herein shall be deemed to create or impose on Purchaser any duty to examine or
investigate any matter or thing for the purposes of verifying the
representations and warranties made by Sellers herein.

required or obligated to pay any amounts necessary to satisfy conditions to or
in order to obtain such governmental regulatory consents other than normal and
customary filing fees and out-of-pocket costs and expenses of the Company
incurred in providing its assistance with respect thereto.  Purchaser shall
diligently and promptly proceed immediately after the date of this Agreement to
make all filings, applications, statements and reports to all governmental
authorities which are required to be made prior to the Closing Date by or on

request of the Sellers, the Purchaser shall provide to the Sellers a status
report as to all such filings and approvals.


       7.5       Confidentiality.  Prior to Closing, unless otherwise required
by law, Purchaser will hold in confidence all confidential information that has
been disclosed by the Sellers and the Company and will not use any such
confidential information except in connection with the transaction, until such
time as such information is otherwise publicly available through sources other

information that becomes generally available to the public, was available on a
non-confidential basis to Purchaser prior to its disclosure pursuant hereto, or
becomes available on a non-confidential basis from a third party who is not
bound to keep such information confidential.  In the event of the termination
of this Agreement, Purchaser will, and will cause its representatives to,
deliver to the Company all documents and other written materials, and all
copies thereof, obtained by Purchaser or on its behalf from the Sellers or the
Company as a result of this Agreement or in connection herewith, whether so

Company shall have standing and may avail itself of any remedy at law or in
equity, including an action for injunctive relief, in the event of a breach or
threatened breach by Purchaser of any of the provisions of this Section 7.5.
The obligations of Purchaser under this Section 7.5 shall survive termination
of this Agreement for any reason whatsoever and shall remain in effect until

releases by the Purchaser, pertaining to this Agreement or the transactions
contemplated hereby shall be submitted to the Company for review and approval
prior to the release by the Purchaser, and shall be released only in a form
reasonably approved by the Company provided however, that (i) such approval
shall not be unreasonably withheld and (ii) such review and approval shall not
be required of statements and announcements by the Purchaser if prior review
and approval would prevent the timely and accurate dissemination of such
statements and announcements as requested to comply, in the judgment of
counsel, with any applicable law, rule or policy.  Sellers and Purchasers shall
issue a press release regarding the execution and delivery of this Agreement
within one day after the date hereof or such other time as Sellers and

the Company or the Subsidiaries; including, without limitation, the following
which shall be considered a material adverse change, to- wit:

                 (i)      A reduction in total monthly dental center and dental

       than $100,000.00 (including attorneys' fees for defending such claim) in
       excess of insurance coverage maintained by the Company which would be

                                       29
<PAGE>   37

       cannot mutually agree as to whether any such litigation or claim is
       reasonably expected to have such potential liability to the Company,
       then the parties shall seek the opinion of a mutually selected third
       party qualified to make such assessment and the opinion of such third
       party as to such potential liability shall be binding upon the parties
       for the purposes hereof; and

                 (h)      At or prior to Closing, the Company shall have
received (and delivered copies thereof to Purchaser) duly executed resignation

and all other conditions to Closing are satisfied but in no event later than
two hundred forty (240) days after the Effective Date unless extended by the
mutual agreement of the Purchasers and the Sellers, subject to earlier

the Closing does not timely occur as stated above, then a party not in default
may immediately terminate this Agreement upon written notice to the other

Agreement shall terminate automatically and without further notice if the
Closing has not occurred within two hundred forty (240) days of the Effective

according to the percentage of the total Purchase Price payable to each Seller
and such amount shall be deposited in an escrow account (the "Post-Closing
Escrow Account") to be maintained pursuant to the Post-Closing Escrow Agreement
among the Sellers, the Purchaser and the Escrow Agent named therein.  The
Post-Closing Escrow Account shall be used solely for the satisfaction of
liabilities of the Sellers under Section 11.2(a) of this Agreement in
accordance with the Post- Closing Escrow Account Agreement.  Nothing contained
herein shall be deemed or construed to limit the liability of a Seller under
Section 11.2(a) of this Agreement except to the extent expressly set forth in
Section 11.4 of this Agreement, and such liability shall expressly not be
limited only to the amount of the funds deposited in the Post- Closing Escrow
Account.

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       11.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
if, prior to the expiration of such two year period, a state of facts shall
have become known which threatens to give rise to a liability against which any
party hereto would be entitled to indemnification hereunder and the indemnified
party shall have given notice of such facts to the indemnifying party, then the
rights of the indemnified party to indemnification with respect to such
liability shall continue until such liability shall have been finally
determined and disposed of (including and subject to disposition by the
expiration of the applicable statute of limitations with respect to such
liability); provided further, however, that if a claim for indemnification is
made pursuant to this Article 11, then such claim for indemnification or any
claim arising out of the wrongful failure to comply with the provisions of this
Article 11 shall survive until the expiration of the applicable period of
limitations with respect to such claim for indemnification; and provided
further, however, that such two year limitation specified above shall not apply
to the extent provided otherwise in Section 11.4(c) below.  With respect to the
representations and warranties of the parties, such representations and
warranties shall be true as of and at the date of the Closing but nothing
contained herein shall be deemed to require or imply that the accuracy of such
representations and warranties shall apply on a continuing basis as to facts
existing after the date of the Closing.  Except to the





                                       32
<PAGE>   40
extent set forth herein, no investigation or examination made by any party
hereto shall constitute a waiver of any representation or warranty and no
representation or warranty shall be merged into the Closing hereunder.
However, to the extent information is apparent on the face of the Schedules or
is otherwise expressly set forth herein, such information shall be deemed to
amend, limit and/or restate any representation and warranties contained herein
to the extent such information is inconsistent with such representation or
warranty.

       11.2      Indemnity.  Subject to the provisions of Section 11.4 below,

                 (a)      Sellers.  Each Seller, jointly and severally (except
as to the representations and warranties contained in Article 3 which shall be
several and not joint), agrees to indemnify and hold harmless the Company, each
Subsidiary, and Purchaser, and their respective shareholders, partners,
directors, officers, employees and agents, from, against, and in respect of,
any loss, liability, claim, demand, or expense, including but not limited to
reasonable attorney, investigation and consultant fees and costs, and of any
other kind whatsoever arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers and the Company
       under this Agreement or under any other agreement or document delivered
       by the Sellers at Closing hereunder; and

                 (ii)     Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers under the Oracare
       DPO Agreement or Frank A. Pettisani, D.D.S. under the Oracare PA
       Agreement or under any other agreement or document delivered by Sellers
       or Frank A. Pettisani, respectively, at the Closing thereunder; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold each
Seller harmless from, against, and in respect of, any loss, liability, claim,
demand, or expense, including but not limited to reasonable attorney's fees and
costs, of any kind whatsoever, arising out of or resulting from any of the
following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Sellers at Closing hereunder;

                 (ii)  Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Sellers are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 11.2(a) above; and





                                       33
<PAGE>   41
                 (iii)  Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       11.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
11.2(a) or 11.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might reasonably be expected to result in any
such claim, demand or action, such party shall promptly notify the other party
or parties who would be obligated to provide indemnity hereunder with respect
to such claim, demand or action, and such other party or parties shall have the
right to take such action as it or they may deem appropriate to resolve such
matter.  The indemnified party or parties shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties, unless the employment of such counsel has been
specifically authorized by the indemnifying party or parties.  Any settlement
of any action subject to indemnity hereunder shall require the consent of the
indemnified and the indemnifying party which consent shall not be unreasonably
withheld and shall be given within five (5) days following the giving of notice
thereof.  The indemnifying party or parties shall not be liable for any
settlement of any action effected without its or their consent, but if settled
with the consent of the indemnifying party or parties or if there be a final
judgment for the plaintiff in any such action, the indemnifying party or
parties shall indemnify and hold harmless the indemnified party from and
against any loss or liability by reason of such settlement or judgment.  If
requested by the indemnifying party, the indemnified party shall cooperate with
the indemnifying party and its counsel and use its best efforts in contesting
any such claim or, if appropriate, in making any counter-claim or
cross-complaint against the party asserting the claim, provided that the
indemnifying party will reimburse the indemnified party for reasonable
out-of-pocket expenses incurred in so cooperating upon presentation of receipts
or other evidence of such expense.  The indemnifying party and its
representatives shall have full and complete access during reasonable hours to
all books, records and files of the indemnified party expressly related to the
defense of any claim for indemnification undertaken by the indemnifying party
pursuant to this Article 11, or for any other purpose in connection therewith;
provided that the indemnifying party shall safeguard and maintain the
confidentiality of all such books, records and files.

       11.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Sellers nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Seventy-Five
Thousand Dollars ($75,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms hereof; provided, however, that the
$75,000 limitation set forth in this Section 11.4(a) shall not apply to the
matters described in Section 11.4(c).  With respect to any indemnifiable loss
payable by the Sellers, the funds in the Post- Closing Escrow Account shall be
used for such purpose first before





                                       34
<PAGE>   42
any recovery is sought directly from a Seller; provided, however, that to the
extent the indemnification loss or losses exceed the funds in the Post-Closing
Escrow Account, then the Purchaser may seek recovery of the amount of such
indemnifiable loss in excess of such funds contemporaneously with the recovery
of any funds in the Post-Closing Escrow Account.

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 11.1 and this Section 11.4(b) shall not apply
to the matters described in Section 11.4(c) not reasonably discoverable by
Seller within the two-year indemnification period set forth in Section 11.1 as
to which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party shall have given notice of such facts to the indemnifying
party and made a claim for indemnification within such two-year period, then
the right to indemnification with respect thereto shall remain in effect until
such matter shall have been finally determined and disposed of and any
indemnification due in respect thereof shall have been paid.

                 (c)      Certain Matters.  The following are the matters 
referred to in Section 11.4(a) and Section 11.4(b):  losses arising from fraud
or an intentional misrepresentation on the part of any Seller or an intentional
breach of any covenant or agreement contained in this Agreement by a Seller.

       11.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Sellers and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       11.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.  In
the event that the Purchaser shall elect to pay or cause the Company to pay any
severance benefits to employees of the Company who may be terminated at or
after the Closing, it is expressly understood that the Sellers shall not be
entitled to receive such severance benefits.

<PAGE>   43
       11.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 4.21 with the appropriate governmental  or regulatory
agencies within five (5) business days of the Effective Date.

                              TERMINATION; WAIVER

       12.1      Termination.  This Agreement may be terminated, and the
transaction may be abandoned, at any time prior to the Closing,  as follows and
in no other manner:

                 (a)      Mutual Consent.  By the mutual consent of Purchaser
and the Sellers;

                 (b)      By Purchaser or Sellers: Condition Precedent.  By
Purchaser or Sellers, upon written notice to the other, if the conditions to
the obligations of such canceling party or parties to consummate the
transaction, in the case of the Sellers, as provided in Article 8 or, in the
case of Purchaser, as provided in Article 9, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this
Agreement unless the failure of the condition is the result of the material
breach of this Agreement by the party seeking to terminate; provided, however,
that, in the event all such conditions have been satisfied except solely the
condition with respect to obtaining all required consents, authorizations, and
approvals of governmental and regulatory agencies set forth in Sections 8.1(a)
and 9.1(a), respectively, and such failure is not due to a breach of this
Agreement by the non- terminating party, such date shall be automatically
extended for four (4) successive thirty (30) day periods so long as such
remains to be the case at the end of each respective thirty (30) day period
provided, however, that in no event shall such date be extended beyond an
aggregate of two hundred forty (240) days after the date of this Agreement
unless extended by the mutual agreement of the Purchaser and the Sellers;

                 (c)      By Purchaser or Sellers: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Sellers, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) two hundred forty (240)
days after the date of this Agreement, unless such date is extended by mutual
agreement of Purchaser and Sellers.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Sellers,
Sellers shall be entitled to retain the Earnest Money.  Any public announcement
of





                                       36
<PAGE>   44
the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

       12.2      Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Sellers, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on

                                NON-COMPETITION

       14.1      Covenant Not to Compete; Non-Solicitation.  For and in
consideration of the purchase by the Purchaser of the Shares pursuant to this
Agreement, and the payments payable by the Purchaser pursuant to this
Agreement, each of Frank A. Pettisani, D.D.S. and Lisa M. Mazzone, severally
and not jointly covenants and agrees that such Seller shall not, directly or
indirectly, through any employees, agents or representatives or as an employer,
consultant, creditor, investor, owner, agent, principal, partner, shareholder,
or through any other kind of ownership (other than ownership of securities of
any publicly held entity in which the Seller, directly or indirectly, in the
aggregate beneficially owns less than two percent (2%) of any class of
outstanding securities), or in any other representative or individual capacity,
do any of the following:

                 (a)      for a period of three (3) years from the date of this
Agreement, engage in (i) the operation of a dental health indemnity insurance
company, (ii) the operation of prepaid dental plans and dental preferred

                 (b)      for a period of three (3) years from the date of this
Agreement, engage in any business which calls upon, solicits, diverts or takes
away any customer or customers of the Company in the Restricted Area for the
purpose of selling or attempting to sell to any of said customers any products
or services similar to any products or services heretofore sold or provided to
any of such customers by the Company excluding, however, life, health, annuity
and vision insurance products; and





                                       39
<PAGE>   47
                 (c)      for a period of five (5) years from the date of this
Agreement, engage in any business which solicits any present or future employee
of the Company or initiates discussions with any such employee regarding his or
her termination or resignation from employment with the Company, so that such
employee may accept employment with, or engagement as a partner, investor,
shareholder, employee, agent or consultant with Seller, directly or indirectly,
as specified above; provided, however, that Seller shall not be prohibited by
this Agreement from employing or soliciting the employment of any employee that
the Company terminates after the date of such termination.

Notwithstanding the foregoing, it is expressly understood that such Sellers
shall be permitted (i) to provide their services to the Purchaser, the Company
and their affiliates in the Dental Services Business, (ii) to provide practice
management services for dental providers, and (iii) to provide dental services
as an individual licensed provider without violating or breaching any of the
foregoing provisions.

Purchaser shall have the right to extend the period of time for which the
provisions of Section 14.1 (a) and (b) above shall be applicable to Lisa M.
Mazzone for an additional two years subject to and upon the following terms (i)
the exercise of such right shall be at the sole election of Purchaser and
Purchaser shall have no obligations to exercise such right (ii) Purchaser shall
give Lisa M. Mazzone notice of the exercise of such right at least ninety (90)
days prior to the end of the three year period, (iii) if Purchaser does not
offer employment to Lisa M. Mazzone or offers employment to Lisa M. Mazzone and
Lisa M. Mazzone accepts such employment, Purchaser shall pay Lisa M. Mazzone
the sum of $200,000 per year for such two-year extension (it being understood
that such amount includes any salary for such employment), and (iv) if
Purchaser offers employment to Lisa M. Mazzone but Lisa M. Mazzone declines
such employment, the Purchaser shall pay Lisa M. Mazzone the amount of $50,000
per year for such two-year extension.

                 14.2     Non-Disclosure.  Each Seller covenants and agrees
that all information concerning the Company, including without limitation (i)
information regarding prices or premiums charged for products and services,
(ii) the assets, liabilities and financial condition of the Company and its
subsidiaries, (iii) the names and identities of customers and analyses of the
amount and types of products and services purchased by each such customer, (iv)
the dental health providers utilized by the Company and its subsidiaries and
the financial arrangements with such providers, and (v) the amount of
compensation to employees, constitute trade secrets and confidential,
proprietary business information which is the property of the Company and that,
unless otherwise required by law, from and after the date of this Agreement:

                 (a)      Each Seller shall use his or her best efforts and
exercise utmost diligence to protect and safeguard all of such trade secrets
and confidential, proprietary information;

                 (b)      Each Seller shall not, directly or indirectly, use,
sell, license, publish, disclose or otherwise transfer or make available to
others any of such trade secrets or confidential, proprietary information;





                                       40
<PAGE>   48
                 (c)      Without the prior written consent of the Company,
each Seller shall not, directly or indirectly, disclose any of such trade
secrets or confidential, proprietary information; and

                 (d)      Each Seller shall not, directly or indirectly, use
for his own benefit or for the benefit of another, any of such trade secrets or
confidential, proprietary information.

It is expressly understood, however, that the foregoing shall not apply to any
information that was generally available to the public on a non-confidential
basis prior to the date of this Agreement or was or becomes generally available
to the public on a non-confidential basis from a third party who is not bound
to keep such information confidential.

       14.3      Nondisparagement.  For a period of three (3) years and after
the date of this Agreement, each Seller further agrees that it shall not make
or publish any statement, written or oral, disparaging the reputation of the
Company or its subsidiaries, executive officers or any of its business services
or products or solicit or encourage any member of any prepaid dental plan of
the Company or its subsidiaries or any third party having a group agreement
with the Company or its subsidiaries to terminate the membership of such person
in the plan of the Company or its subsidiaries or to terminate such group
agreement.

       14.4      Reasonableness; Reformation.  Each Seller acknowledges and
agrees that (i) the provisions of this Article 14 are ancillary to the
transaction pursuant to which the Seller sold and the Purchaser acquired the
Shares, (ii) the provisions of this Agreement contain reasonable limitations as
to time, geographical area and scope of activities to be restrained and do not
impose a greater restraint than is necessary to protect goodwill and other
business interests of the Company and its subsidiaries, (iii) if any portion of
the covenants and agreements set forth in this Agreement are held to be
invalid, unreasonable, arbitrary or against public policy, then such portion of
such covenants shall be considered divisible as to time, scope of activities
covered, and geographical area, and (iv) if any court of competent jurisdiction
determines the specified time period, scope of activities covered, or the
specified geographical area applicable to any provision of this Agreement to be
invalid, unreasonable, arbitrary or against public policy, a lesser time
period, scope of activities covered, and/or geographical area which is
determined to be reasonable, non-arbitrary and not against public policy may be
enforced against each Seller.

       14.5      Remedies for Breach.  If a Seller has failed to satisfactorily
cure any breach or threatened breach of any covenant or agreement contained
herein within ten (10) days after written notice of such breach or threatened
breach given by the Purchaser to each Seller, any one or more of the following
remedies, as selected by the Purchaser in its sole discretion, shall be
available to the Purchaser in the event of a breach of this Agreement by the
Seller hereunder:

                 (a)      Specific Performance.  In the event of a breach or
threatened breach of any covenant or agreement of a Seller in this Agreement,
remedies at law will not adequately compensate the Purchaser for its injuries
incurred as a result  thereof.  Accordingly, injunctive





                                       41
<PAGE>   49
and/or equitable relief shall be available to the Purchaser to specifically
enforce this Agreement and prevent such breach and any continued breach of any
covenant and agreement herein.

                 (b)      Suit for Damages.  In addition to the remedies stated
in Section 14.5(a) above, in the event of any breach of any covenant or
agreement of a Seller herein, Purchaser may sue for damages arising out of such
breach and otherwise enforce this Agreement and obtain all other remedies
available to the Seller under applicable law.


                                   ARTICLE 15
                                  ARBITRATION

       15.1      Arbitration Procedure.  Subject to the provisions of Section
15.7 below, in the event any matters in Dispute arising out of or relating to
this Agreement (including, but not limited to, actions for injunctive or
declaratory relief) (hereinafter collectively "arbitrable issues") cannot be
settled by agreement between the parties such controversy or dispute shall be
submitted for arbitration in Philadelphia, Pennsylvania, and for this purpose
each party hereby expressly consents to such arbitration in such forum.  The
arbitration process shall proceed as follows:

                 (a)      Step One.  In the event of a Dispute, the disputing
party (herein so called) may at any time notify the other party or parties
("answering party") in writing that the disputing party demands to pursue
arbitration as provided in Step Two below, setting forth in specific terms the
disputing party's proposed statement of the matters in Dispute to be submitted
to arbitration and the name and address of the arbitrator selected by the
disputing party.  Within five (5) business days following receipt of the
disputing party's written arbitration demand complying with the requirements of
this Step One, each answering party shall notify the disputing party in
writing, setting forth in specific terms the answering party's proposed
statement of the matter in Dispute and identifying the name and address of the
arbitrator selected by such answering party.  For purposes of this Section
15.1, all persons constituting the Sellers shall act as one party in selecting
an arbitrator, whether as a disputing party or as an answering party.

                 (b)      Step Two.  The two (2) or more arbitrators so
selected shall meet and confer within twenty (20) business days after receipt
by the disputing party of all of the answering parties' written notices as
called for under Step One above, and if they are unable within said twenty (20)
day period to reach a decision on the matters in Dispute, they shall, at the
expiration of said twenty (20) day period, jointly select a neutral arbitrator.
If said arbitrators are unable to choose a neutral arbitrator, any party may
request the AAA to appoint an additional arbitrator from its National Panel of
Commercial Arbitrators.  Any party to this Agreement may advise the AAA that
time is of the essence and that the parties to this Agreement would like such
selection as soon as is reasonably possible, it being expressly understood in
such AAA selection process that the selection is in the sole discretion of the
AAA, and that the AAA shall not be required by reason of this Agreement to
consult with the parties to this Agreement in said selection process; provided
that all arbitrators, including the additional





                                       42
<PAGE>   50
arbitrator selected by the AAA, shall be disinterested individuals
knowledgeable in commercial transactions.  Upon selection of the additional
arbitrator, all arbitrators shall within ten (10) business days thereafter
convene an arbitration proceeding at a date, time and place (in metropolitan
Philadelphia, Pennsylvania) designated by said arbitrators by a majority vote,
written notice of which shall be given to the parties not later than seven (7)
calendar days prior to said hearing date.  At the hearing, each party may be
represented by counsel and present testimony and evidence.  If at the
commencement of the hearing the parties cannot agree on a joint statement of
the matters in Dispute to be submitted to the arbitrators, the arbitrators
shall be empowered to frame the submission issue(s).  A Certified Court
Reporter's transcript may be demanded by any party or by the arbitrators and
said official transcript shall be prepared, completed, and delivered to the
arbitrators with copies to each party within ten (10) business days following
the conclusion of the hearing.  Arbitration sessions following the initial
session, if necessary, shall be scheduled by the arbitrators so that the
arbitration proceedings (i.e., presentation of evidence and/or oral arguments)
are completed within twenty (20) days of the initial session.  Each party shall
be given the opportunity to file with the arbitrators simultaneous written
briefs five (5) business days following receipt by the arbitrators of the
official transcript but, if no transcript is demanded as provided in this
Agreement, said briefs shall be filed simultaneously five (5) business days
following conclusion of the hearing.  Copies of any such briefs shall be
provided to the other party concurrently upon filing with the arbitrators.

                 (c)      Step Three.  Within ten (10) business days following
the receipt by the arbitrators of the brief(s) (or within ten (10) business
days following conclusion of the hearing if all parties waive briefs), the
arbitrators shall make and deliver to the parties their decision and award in
writing.  The arbitrators shall have the authority to enter any award or to
grant any relief which could be obtained in a court of competent jurisdiction
and reasonable attorneys', arbitrators' and experts' fees and expenses of
arbitration may be awarded as the arbitrators see fit, consistent with the
provisions of this Agreement.  The arbitrators shall have no authority to
modify, amend or alter the provisions of this Agreement and shall base their
decision and award on applicable law, the language contained in this Agreement
and the facts giving rise to the Dispute as presented on the record at the
hearing.  The arbitrators shall issue a written opinion explaining the basis
for their findings.

       15.2      Self-Execution.  It is expressly understood between the
parties that this Article 15 is a self- executing arbitration provision and
that any party may unilaterally select an arbitrator if the other party refuses
to arbitrate.  It is further expressly agreed that said unilaterally-selected
arbitrator may proceed to arbitrate the issue(s) and the arbitration and
decision shall be self-executing and therefore shall not require the order of
any Court to proceed.  The parties may, however, mutually stipulate in writing
to extend or to shorten the prescribed time periods (including a stipulation to
expedite the referral and submission to arbitration).  All provisions of this
Agreement not in dispute shall be observed and performed without interruption
during the pendency of any proceeding called for under this Article 15.

       15.3      Arbitrator's Fees.  If an additional arbitrator is required
pursuant to Step Two under Section 15.1, each party shall pay its pr rata share
of any required retainer or other payments required by such arbitrator upon
such arbitrator's demand, with the ultimate





                                       43
<PAGE>   51
responsibility for the arbitrators' fees to be determined by the arbitrators in
the final arbitration award pursuant to Step Three of Section 15; otherwise,
each party shall bear its own costs and expenses in connection with any
proceedings under this Article 15 and, in any event, each party shall pay the
fees of the arbitrator it selects.

       15.4      Rules Governing Arbitration.  In all other respects, the
arbitration shall be conducted pursuant to the then-existing Commercial Rules
of the AAA to the extent such rules are not inconsistent with any provision of
this Agreement.  Subject to the foregoing, the arbitrators shall determine the
scope and extent of permissible discovery, if any.

       15.5      Entry of Award.  The award of the arbitrators may be entered
as a final judgment by any court of competent jurisdiction.

       15.6      Injunctive Relief.  Notwithstanding the provisions of this
Article 15 to the contrary, each party shall be entitled to seek temporary or
preliminary injunctive relief from a court of competent jurisdiction if the
failure to immediately obtain injunctive relief will result in irreparable harm
to that party.  The jurisdiction of the court shall extend only to such relief
and any request for permanent injunctive relief shall remain subject to the
arbitration provisions of this Agreement.

       15.7      Non-Applicability to Note.  Notwithstanding any provision of
this Article 15 to the contrary, the provisions of this Article 15 shall
expressly not apply to any dispute arising out or relating to the Note.


                                   ARTICLE 16
                                 MISCELLANEOUS

       16.1      Further Instruments.  The parties hereto agree to execute and
deliver such instruments and take such other action as shall be reasonably
necessary, or as shall be reasonably requested by any other party, in order to
carry out the transactions, agreements and covenants contemplated in this
Agreement at or prior to the Closing Date.

       16.2      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to
such other party(ies) at the address set forth below, and by (i) depositing the
same so addressed, postage prepaid, first class, certified or registered, in
the United States mail (herein referred to as "Mailing"), (ii) overnight
delivery by a nationally recognized overnight courier service (e.g. UPS,

overnight courier; if by personal delivery, upon such delivery; or if by
facsimile, the day of transmission if made within customary business hours, or

                                       45
<PAGE>   53
liable for any and all of Purchaser's obligations under this Agreement.  None
of the Sellers shall be entitled to assign any of their respective rights or
obligations under this Agreement; provided, however, that the rights and
obligations of a Seller may be assigned by operation of law or may be assigned
to an individual retirement account, pension plan, trust or other entity under
the control of such Seller but any such assignment shall not relieve or release
such Seller of any obligations hereunder as a result of such assignment and
that, in addition to such Seller remaining liable, any such assignee shall
assume and become liable for any and all of such Seller's obligations under
this Agreement. In connection with any such assignment, a Seller may transfer
all or any portion of the Shares owned by the Seller and thereby effect an
assignment on the basis specified above.

       16.5      Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

       16.7      Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

       16.8      Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

       16.9      Attorney's Fees and Costs.  In the event of a breach by any
party to this Agreement and commencement of a subsequent legal action in a
court of law or forum of arbitration, or in the event legal counsel is
consulted in the event of any such breach or in anticipation of any such
prospective legal action, the prevailing party in any such dispute shall be
entitled to reimbursement of reasonable attorney's fees and court costs,
including, but not limited to, the costs of expert witnesses, transportation,
lodging and meal costs of the parties and witnesses, costs of transcript
preparation and other reasonable and necessary direct and incidental costs of
such dispute.  A party shall be deemed to be a "prevailing party" under this
Section only if:






                                       46
<PAGE>   54
                 (a)      the judgment or award against it is equal to or less
than eighty percent (80%) of that party's written settlement offer; or,

                 (b)      the judgment or award in its favor is equal to or
greater than one hundred and twenty percent (120%) of that party's written
settlement demand.

The party responsible for attorneys' fees and costs under this provision shall
only be responsible for those attorney's fees and costs incurred from a point
in time commencing twenty (20) days after receipt of the offer or demand of
settlement under (a) or (b) above.  Adjudication of a party's entitlement to
counsel fees shall be by way of a non-jury proceeding following adjudication of
the underlying action.

       16.10     Coordination with OraCare DPO Agreement and OraCare PA
Agreement.  Purchaser and Sellers agree that the consummation of the
transactions contemplated by this Agreement shall constitute a condition
precedent to the obligations of the Sellers and the Purchaser under the OraCare
DPO Agreement and the OraCare PA Agreement.  For such purpose, the Sellers as
the Sellers and Purchaser as the Purchaser under the OraCare DPO Agreement and
the OraCare PA Agreement agree that such agreements shall be deemed to be
amended and supplemented to add the provisions of to Section 15.10 as an
additional condition precedent to the obligations of the parties thereto
notwithstanding any provision of such agreements to the contrary.

       16.11     Time.  Time is of the essence under this Agreement.

       16.12     Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
New Jersey.

       16.13     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                                   EXHIBIT B

         For the purposes of Section 2.3 of the Stock Purchase Agreement, the
following definitions shall apply in determining the Combined Earnings of the
Company.  The overall intent of the following definitions is to define the
Combined Earnings of the Company as the earnings before interest, income taxes,
depreciation and amortization for all Dental Business conducted by the
Purchaser and its direct and indirect subsidiaries, including, without
limitation, Oracare Consultants, Inc., Oracare DPO, Inc. and Oracare Dental
Associates, P.A. (collectively "Oracare") in the States of New Jersey and
Pennsylvania.

         A.      "Combined Earnings of the Company" shall mean the Revenues
less Dental Expenses and less Selling, General and Administrative Costs, but
before any reduction for interest expense, depreciation, amortization or income
taxes.

         B.      "Revenues" shall mean the sum of all revenues received with
respect to Dental Business conducted by the Purchaser and its direct or
indirect subsidiaries, including, without limitation, Oracare, in the States of
New Jersey and Pennsylvania.

         C.      "Dental Expenses" shall mean the dental service expenses paid
to dental providers with respect to the Dental Business of the Purchaser and
its direct or indirect subsidiaries, including, without limitation, Oracare,
conducted in the States of New Jersey and Pennsylvania (less the dental service
expenses actually paid to the dental practices managed by the Purchaser and its
subsidiaries, i.e., the usual elimination entry for consolidation purposes)
plus all operating costs of the dental practices managed by the Purchasers and
its subsidiaries in the States of New Jersey and Pennsylvania.

         D.      "Selling, General and Administrative Costs" shall mean all
direct costs of the Dental Business conducted by the Purchaser and its direct
or indirect subsidiaries, including, without limitation, Oracare, in the States
of New Jersey and Pennsylvania and all of the direct costs of the dental
practice business managed by the Purchaser and its subsidiaries in the States
of New Jersey and Pennsylvania including, without limitation, premium, excise
and franchise (but not income) taxes, brokerage commissions, employee
compensation, rent and telephone expense.  In the event that certain existing
operations of Oracare are relocated from New Jersey to Dallas (such as
accounting and accounts payable) the costs to be counted as part of the
Selling, General and Administrative Costs shall be the year-to- date actual
cost of such activities before relocation plus, for each month thereafter of
the applicable measurement period, a fixed amount per month equal to the
average of the actual cost of such activities in the last twelve months prior
to such change as performed in New Jersey or Pennsylvania prior to such
relocation.

         E.      "Dental Business" shall mean all business relating to the
ownership and operation of prepaid dental plans, the management of dental
practices, the dental indemnity insurance business, the operation of a dental
preferred provider organization or any other business related in any way to the
provision of dental health care benefits or services in the States of New
Jersey or Pennsylvania.





                                       1
<PAGE>   58
         F.      All determination relating to the Combined Earnings of the
Company shall be made on an accrual basis in accordance with generally accepted
accounting principles.

         G.      In the event that any goods and services are rendered or sold
by an affiliate of the Purchaser in relation to the Dental Business conducted
in the States of New Jersey and Pennsylvania, such goods and services shall be
for consideration equivalent to that which could be obtained from an
unaffiliated third party in an arms-length transaction and the costs of such
goods and services will be included in Selling, General and Administration
Costs.  Purchaser agrees that the expenses utilized for the purposes of the
calculation of the Combined Earnings of the Company shall not include any
management, consulting or similar fee paid to the Purchaser, or any affiliate
of the Purchaser, other than expenses relating to certain existing operations
relocated from New Jersey to Dallas to be accounted for as specified in
Paragraph D above.

         H.      Purchaser shall not make any charge for a cost or expense to
the Dental Business in the States of New Jersey and Pennsylvania for (a) any
expenses incurred by Purchaser in connection with the acquisition of Oracare,
(b) any cost unrelated to the operation of the Dental Business in the States of
New Jersey and Pennsylvania, (c) any component of general or administrative
overhead calculated on the basis of costs incurred by the Purchaser and its
affiliates.

         I.      Dental Expenses and Selling, General and Administrative Costs
shall be accounted for on the basis of the categories/item as shown on Exhibit
A  attached hereto.

         J.      In the event that Purchaser, directly or indirectly, acquires
any other entity engaged in the Dental Business in the States of New Jersey and
Pennsylvania (or the assets of any such business) it is agreed and understood
that the earnings of such entity determined for a twelve month period ending as
of the month preceding the month in which such acquisition occurs shall be
added to the "base" earnings amount which must be exceeded for the respective
year relating to each Additional Payment; and the actual results of the
operations of such entity (or assets) from the beginning of the respective year
shall be included in determining the Combined Earnings of the Company for the
year in which the acquisition occurs and each year thereafter with respect to
which an Additional Payment is payable.  Notwithstanding the foregoing, in the
event the Purchaser acquires any entity or the assets thereof engaged in the
Dental Business in the States of New Jersey and Pennsylvania, which has
negative earnings for the twelve month period prior to the date of the
acquisition, then no adjustment shall be made for the purposes of determining
the base earnings used in calculating an additional payment and the results of
operations for such entity shall not be included in determining the Combined
Earnings of the Company until and including the first calendar month as such
entity (or as such) has positive earnings.

         K.      In the event that the Purchaser disposes of all or
substantially all of any line of business constituting a part of the Dental
Business engaged in the States of New Jersey and Pennsylvania of Oracare (or
the assets thereof) prior to consummation of the Stock Purchase Agreement at
any time prior to December 31, 1998, it is agreed and understood that the
earnings





                                       2
<PAGE>   59
of such line of business for the twelve month period ending as of the end of
month preceding the month in which such disposition occurs shall be deducted
from the base earnings used for determining the Additional Payment; and the
actual results of operations of such line of business from the beginning of the
respective year in which the disposition occurs shall not be included in
determining the Combined Earnings of the Company for the year in which the
disposition occurs and each year thereafter with respect to which an Additional
Payment is made.

         L.      Purchaser agrees that, until all Additional Payments have been
made, the Purchaser and the Company shall provide each Seller with the
following information at the same time such information becomes available to
Purchaser: (i) quarterly financial statements of Oracare; (ii) annual financial
statements of Oracare; (iii) notice of any material claims or allegations
against Oracare; (iv) notice of any events, conditions, acts, facts or
omissions which might be reasonably expected to have a material adverse effect
on the assets, properties, conditions (financial or otherwise), operating
results or prospects of Oracare.

parties hereto. Notwithstanding the foregoing or anything herein to the
contrary, however, nothing herein is intended to release or limit in any manner

Paragraph 2 hereof.

         2. Exception. Notwithstanding anything herein to the contrary, the

         On or before January 1 of each year thereafter, the Company shall

         8. Confidentiality/Trade Secrets. The Executive acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and thereafter, the Executive
covenants and agrees as follows:

                  (a) that he shall use his best efforts and exercise utmost
         diligence to protect and safeguard the trade secrets and confidential
         and proprietary information of the Company including but not limited
         to the identity of its customers and suppliers, its arrangements with
         customers and suppliers, and its technical data, records, compilations
         of information, processes, and specifications relating to its
         customers, suppliers, products and services;

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         Provided, however, that "confidential information" shall not include
information regarding customers, suppliers, technical data, processes and
specifications which are generally known in the industry or are already in the
public domain other than through a breach of this provision by Executive or
another person in violation of a duty of confidentiality owed to the Company.

         9. Non-Competition. The Executive covenants and agrees that, during
the period of his employment, and so long as any severance payments are being
made hereunder, he shall not, without the prior written consent of the Board,
directly or indirectly, as an employee, employer, consultant, agent, principal,
partner, shareholder, corporate officer, director, or through any other kind of
ownership (other than ownership of securities of publicly held corporations of
which the Executive owns less than two percent (2%) of any class of outstanding
securities) or in any other representative or individual capacity, engage in
any business or render any services to any business that is in competition in
any manner whatsoever with the business of the Company.

         10. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8 and 9 of this Agreement shall continue to be binding
upon the Executive, notwithstanding the termination of his employment with the
Company for any reason whatsoever. Such covenants shall be deemed and construed
as separate agreements independent of any other 



                                       3
<PAGE>   66


provisions of this Agreement and any other agreement between the Company and
the Executive. The existence of any claim or cause of action by the Executive
against the Company, whether predicated on this Agreement or otherwise, shall
not constitute a defense to the enforcement by the Company of any or all of
such covenants. It is expressly agreed that the remedy at law for the breach of
any such covenant is inadequate and the injunctive relief shall be available to
prevent to the breach or any threatened breach thereof.

         11. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         ninety (90) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon ninety (90) days prior written notice to the Executive.

                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:

                           (1) If the Executive becomes disabled for a period
                  of more than thirty (30) consecutive days;

                           (2) If the Executive for reasons other than illness
                  or injury absents himself from his duties without the consent
                  of the Board for more than ten (10) consecutive days;

                           (3) If the Executive should die (effective on the
                  date of death);

                           (4) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (5) If the Executive should willfully breach or
                  habitually neglect his duties which he is required to perform
                  under this Agreement or otherwise fail to comply with the
                  terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in
                  Paragraphs 8 and 9 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by him prior to the date of termination as provided herein
with any incentive bonus computed on a pro rata basis to and including such
date of termination. In addition, in the event the Company terminates this
Agreement without cause pursuant to Paragraph 11(b) above, the Executive shall
be entitled to receive a severance payment as liquidated damages for, and in
lieu of, any and all damages

which he may incur as a result of such termination in an amount equal to his
base salary then in effect which otherwise would have been payable over the
remaining term of this Agreement (payable in installments on the regular
payroll dates of the Company). In addition, the Company shall continue the
health benefits of the Executive during the period such severance payments are
being made. The Executive shall be entitled to no further compensation as of

shall be without prejudice to any right or remedy to which the terminating

         Agreement.

                  (f) Titles. Titles of the paragraphs herein are used solely

                  shall be payable within ten (10) days after the end of the

         7. Reimbursement of Expenses. Subject to such rules and procedures as
from time to time are specified by the Company acting by and through the
President of the Company and/or the Board, the Company shall reimburse the
Executive on a monthly basis for reasonable business expenses necessarily
incurred in the performance of his duties under this Agreement.

         8. Confidentiality/Trade Secrets. The Executive acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and thereafter, the Executive
covenants and agrees as follows:

                  (a) that he shall use his best efforts and exercise utmost
         diligence to protect and safeguard the trade secrets and confidential
         and proprietary information of the Company including but not limited
         to the identity of its customers and suppliers, its arrangements with
         customers and suppliers, and its technical data, records, compilations
         of information, processes, and specifications relating to its
         customers, suppliers, products and services;

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Executive or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Executive upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         Provided, however, that "confidential information" shall not include
information regarding customers, suppliers, technical data, processes and
specifications which are generally known in the industry or are already in the
public domain other than through a breach of this provision by Executive or
another person in violation of a duty of confidentiality owed to the Company.

         9. Non-Competition.

                  (a) The Executive covenants and agrees that, during the
         period of his employment, he shall not, without the prior written
         consent of the Board, directly or indirectly, as an employee,
         employer, consultant, agent, principal, partner, shareholder,
         corporate officer, director, or through any other kind of ownership
         (other than ownership of securities of publicly held corporations of



                                       3
<PAGE>   73
         which the Executive owns less than two percent (2%) of any class of
         outstanding securities) or in any other representative or individual
         capacity, engage in any business or render any services to any
         business that is in competition in any manner whatsoever with the
         business of the Company.

                  (b) In addition, after termination of this Agreement, the
         Executive covenants and agrees that, for a period of one year, he
         shall not, directly or indirectly, as an employee, agent, consultant, 
         owner, principal, partner, shareholder or officer engage in any 
         business which calls upon, solicits, diverts or takes away any customer
         or customers of the Company in the State of New Jersey for the purpose
         of selling or attempting to sell any of such customers any prepaid 
         dental plan products or any other products or services similar to the 
         products and services then being sold by the Company and its 
         affiliates.

         10. Remedies for Breach of Covenants of the Executive. The covenants
set forth in Paragraphs 8 and 9 of this Agreement shall continue to be binding
upon the Executive, notwithstanding the termination of his employment with the
Company for any reason whatsoever. Such covenants shall be deemed and construed
as separate agreements independent of any other provisions of this Agreement
and any other agreement between the Company and the Executive. The existence of
any claim or cause of action by the Executive against the Company, whether
predicated on this Agreement or otherwise, shall not constitute a defense to
the enforcement by the Company of any or all of such covenants. It is expressly
agreed that the remedy at law for the breach of any such covenant is inadequate
and the injunctive relief shall be available to prevent to the breach or any
threatened breach thereof.

         11. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Executive may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         ninety (90) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon ninety (90) days prior written notice to the Executive.

                  (c) Involuntary with Cause. The Board may, upon written
         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:

                           (i) If the Executive becomes disabled for a period
                  of more than thirty (30) consecutive days;

<PAGE>   74



                           (ii) If the Executive for reasons other than illness
                  or injury absents himself from his duties without the consent
                  of the Board for more than ten (10) consecutive days;

                           (iii) If the Executive should die (effective on the
                  date of death);

                           (iv) If the Executive should be convicted of a crime
                  punishable by imprisonment; and

                           (v) If the Executive should willfully breach or
                  habitually neglect his duties which he is required to perform
                  under this Agreement or otherwise fail to comply with the
                  terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in
                  Paragraphs 8 and 9 hereof.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Executive shall be entitled to
compensation earned by him prior to the date of termination as provided herein
to and including such date of termination. In addition to the foregoing, so
long as the Executive complies with the provisions of Section 9(b) of this
Agreement and the termination of this Agreement was "without cause," under
Section 11(b) of this Agreement, then the Executive shall be entitled to be
paid as a severance payment for liquidated damages for, and in lieu of, any and
all damages which he may incur as a result of such termination (i) an amount
equal to his base salary which otherwise would have been payable over the
greater of: (a) one year after the date of termination or (b) the remaining
term of this Agreement (payable in installments on the regular payroll dates of
the Company) and (ii) all commission income to which the Executive would have
been entitled under Section 4(b) above if his employment had not been
terminated with respect to premiums paid to and received by the Company during
the same period. In addition, the Company shall continue the health benefits of
the Executive during the period such severance payments are being made. The
Executive shall be entitled to no further compensation as of the date of
termination under this Agreement. Any termination of this Agreement shall be
without prejudice to any right or remedy to which the terminating party may be
entitled either at law, in equity, or under this Agreement.

         12. Notices. Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to
such other party(ies) at the address set forth below, and by (i) depositing the

Office delivery days following the date of Mailing; one day after timely
delivery to an overnight courier; or if by personal delivery, upon such
delivery.

         held to be illegal, invalid, or unenforceable under present or future
         laws effective during the term hereof, such provision shall be fully
         severable and this Agreement shall be construed and enforced as if
         such illegal, invalid, or unenforceable provision had never comprised
         a part hereof; and the remaining provisions hereof shall remain in
         full force and effect and shall not be affected by the illegal,

         Agreement.

                  (f) Titles. Titles of the paragraphs herein are used solely
         for convenience and shall not be used for interpretation or construing

                         POST-CLOSING ESCROW AGREEMENT


         This Post-Closing Escrow Agreement (the "Agreement") is made as of the
_______ day of ________, 1996 among Frank A. Pettisani, D.D.S., Lisa M.
Mazzone, Frank A. Pettisani, Jr., D.D.S., Charles A. Costa, and Donna Costa
(collectively referred to herein as the "Sellers"), United Dental Care, Inc., a
Delaware corporation ("Purchaser"), and Prudential Securities (the "Escrow
Agent").

         WHEREAS, Purchaser, Sellers, OraCare Consultants, Inc., a New Jersey
corporation (the "Company") entered into a Stock Purchase Agreement, dated as
of September ___, 1996 (the "Stock Purchase Agreement"), providing for the sale
of all of the issued and outstanding shares of capital stock of the Company by
Sellers to Purchaser; and

         WHEREAS, pursuant to the Stock Purchase Agreement, Sellers agreed to
place the sum of Five Hundred Thousand Dollars ($500,000) of the Purchase Price
paid to Sellers in escrow for the purposes hereinafter set forth upon the
consummation of the transactions contemplated by the Stock Purchase Agreement;
and

         WHEREAS, the transactions contemplated by Stock Purchase Agreement
have been consummated on the date hereof and the parties desire to effectuate
the provisions of the Stock Purchase Agreement with respect to such
post-closing escrow fund;

         NOW, THEREFORE, in consideration of the premises and the mutual terms
and conditions of the Reorganization Agreement hereof, the parties hereby agree
as follows:

         1. Escrow Money. Simultaneously with the execution of this Agreement,
Sellers have deposited with the Escrow Agent the sum of Five Hundred Thousand
Dollars ($500,000) (the "Escrow Money") which constitutes a portion of the
purchase price paid to the Sellers pursuant to the Stock Purchase Agreement.
The respective interests of the Sellers in the Escrow Money as of the date of
this Agreement shall be according to the same ownership percentages of the
outstanding shares of capital stock of the Company shown on Exhibit A to the
Stock Purchase Agreement. The receipt of the deposit of the Escrow Money is
hereby acknowledged by the Escrow Agent by its execution hereof.

         2. Escrow Account. The Escrow Money shall be held in escrow by the
Escrow Agent pursuant to the terms and conditions of this Agreement. Upon
receipt of the Escrow Money, the Escrow Agent shall place the Escrow Money into
any money market mutual fund rated AAA or higher by Standard and Poor's or
Moody's, treasury bills or other instruments selected in writing by Sellers
with a maturity date not in excess of ninety (90) days under the



                                      1
<PAGE>   79



following terms and conditions: (i) under the names of Sellers in proportion to
their respective interests in the Escrow Money as set forth in Section 1 above
and (ii) under the social security numbers of Sellers. It is understood and
agreed that the Escrow Agent will be issuing a 1099 INT Statement to each
Seller and the Internal Revenue Service. Sellers shall have the responsibility
as to any 1099 INT reporting thereof. The Escrow Money shall at all times be
held in a separate account and shall only be delivered pursuant to the terms
and conditions of this Agreement.

         3. Terms of Escrow. The Escrow Money shall be held as a fund available
to satisfy any obligations of Sellers to Purchaser which may arise under
Section 11.2(a) of the Stock Purchase Agreement in the manner set forth below:

                  (a) In the event that Purchaser shall assert a claim or
         claims against Purchaser arising out of or relating to any matter with
         respect to which Purchaser asserts that it is entitled to be
         indemnified by Sellers pursuant to Section 11.2(a) of the Stock
         Purchase Agreement (collectively, the "Claims"; singularly a "Claim"),
         Purchaser shall furnish written notice of the Claim (the "Notice of
         Claim") to Sellers and the Escrow Agent on or before the day preceding
         the second anniversary of the Effective Date of the Merger (the
         "Release Date"). The Notice of Claim: (i) shall state in reasonable
         detail the nature of Sellers' alleged liability; (ii) shall state the
         amount of the payment that Purchaser claims it is entitled to receive
         from the Escrow Money based upon Purchaser's estimate of the potential
         loss; and (iii) shall further provide a particularized statement
         explaining the basis for such estimate. Sellers shall have thirty (30)
         days after receipt of the Notice of Claim in which to advise the
         Escrow Agent and Purchaser that it disputes the Claim by delivering
         written notice of Sellers' dispute ("the Notice of Dispute") to the
         Escrow Agent and Purchaser. The Notice of Dispute may contest all or
         any portion of the Notice of Claim based on a dispute concerning the
         existence of a Claim, Sellers' liability, the estimated amount of the
         alleged loss or any other related matter.

                  (b) If Sellers fail to deliver a Notice of Dispute within
         such thirty (30) day period, Sellers shall be deemed to have been
         acknowledged that Purchaser is entitled to payment as set forth in the
         Notice of Claim and shall be deemed to have directed the Escrow Agent
         to disburse such payment (the "Claim Payment") to Purchaser. In the
         event a Notice of Dispute is timely delivered, then the undisputed
         portion of the Claim, if any (the "Undisputed Claim Payment"), shall
         be promptly disbursed to Purchaser and only the sum that is subject to
         a dispute shall be held by the Escrow Agent until the Claim is
         resolved; provided, however, that any Claim which is based upon the
         assertion or threat of a third party claim against Purchaser shall be
         conclusively deemed to be resolved two (2) years after the Notice of
         Claim is delivered unless litigation, arbitration, assessment or some
         other formal proceeding is commenced against Purchaser within that two
         (2) year period. If such a formal proceeding is not commenced within
         such two (2) year period, then the Claim shall be deemed abandoned and
         of no further force and effect for purposes of this Agreement. In the
         event a formal proceeding is commenced within the two (2) year period,
         then the resolution of the Claim will occur only upon the resolution
         of such proceeding and any related appellate proceedings.

<PAGE>   80



                  (c) Subject to Sellers' right to dispute a Claim, once a
         Notice of Claim is delivered to the Escrow Agent, the Escrow Agent
         shall not permit the Escrow Money to be reduced by disbursement to
         Sellers to an amount which is less than the difference between the
         aggregate dollar amount of each Claim for which a Notice of Claim was
         delivered on or prior to the Release Date in accordance with the terms
         of Section 3(a) above less the amount of $75,000 (unless such claim is
         not subject to the Threshold limitation as specified in Section
         11.4(a) of the Stock Purchase Agreement and such fact is so stated in
         the Notice of Claim). Furthermore, if the amount of any Claim or the
         aggregate amount of any Claims should ever exceed the sum of $75,000
         plus the amount of the Escrow Money, then no portion of the Escrow
         Money shall be disbursed pursuant to Section 3(d) below, during such
         time that such a deficit exists.

                  (d) On the six (6) month anniversary after the Effective
         Date, following the payment of all fees and expenses due to Escrow
         Agent, the Escrow Agent shall unconditionally disburse to Sellers
         fifty percent (50%) the Escrow Money (i.e. $250,000) to the extent it
         exceeds the sum of: (i) the aggregate dollar amount of each Claim
         previously paid pursuant to the terms of this Agreement and the Stock
         Purchase Agreement; plus (ii) the aggregate dollar amount of any then
         existing Claim or Claims for which a Notice of Claim was delivered on
         or prior to the Release Date in accordance with the terms of Section
         3(a) above less the amount of $75,000 (unless such claim is not
         subject to the Threshold limitation as specified in Section 11.4(a) of
         the Stock Purchase Agreement and such fact is so stated in the Notice
         of Claim). The remaining portion of the fifty percent (50%) Escrow
         Money not distributed, if any, shall continue to be held pursuant to
         the terms of this Agreement. On the Release Date following payment of
         all fees and expenses due to the Escrow Agent, the Escrow Agent shall
         unconditionally disburse to Sellers the Escrow Monies to the extent it
         exceeds the sum of (i) the aggregate dollar amount of each Claim
         previously paid pursuant to the terms of this Agreement and the Stock
         Purchase Agreement; plus (ii) the aggregate dollar amount of any then
         existing Claim or Claims for which a Notice of Claim has delivered on
         or prior to the Release Date in accordance with the terms of Section
         3(a) above less the amount of $75,000 (unless such Claims not subject
         to the Threshold limitation as specified in Section 11.4(a) of the
         Stock Purchase Agreement and such fact is so stated in the Notice of
         Claim). The remaining portion of the Escrow Money not distributed, if
         any, shall continue to be held pursuant to the terms of this Agreement
         and shall be unconditionally disbursed to Sellers (or Purchaser, if
         appropriate), in one or more disbursements, from time to time, upon
         final resolution of all Claims involving such funds.

                  (e) Unless delivery is made in person at the Escrow Agent's
         office or unless the Escrow Agent is properly instructed in writing by
         Purchaser or Sellers, as the case may be, to make delivery in such
         other manner, the Escrow Agent shall be deemed to have properly
         delivered to Purchaser or Sellers, as the case may be, such funds as
         Purchaser or Sellers are entitled to receive, upon placing the same in
         United States Mail in a suitable package or envelope, registered or
         certified mail, return receipt requested, postage prepaid, addressed
         to the address listed in Section 7 hereof or such other address as may
         be furnished to the Escrow Agent in writing.

                  (f) Without any notice to or consent by Purchaser, interest,
         dividends, distributions or other earnings on the Escrow Money shall
         be released to Sellers by the Escrow Agent on a monthly basis pursuant
         to the instructions of Sellers or the assigns of the Sellers, both
         before and after the Release Date.

                  (g) Notwithstanding any other provision hereof which shall
         direct the release of all or a part of the Escrow Money on a
         particular date, without the prior written consent of Purchaser and
         Sellers as to any withdrawal before the Release Date, and without the
         prior written consent of Sellers as to any withdrawal on or after the
         Release Date, the Escrow Agent shall not withdraw any investment of
         the Escrow Money prior to the maturity date of such investment to make
         a payment to Purchaser or Sellers hereunder if such withdrawal will
         cause an early withdrawal penalty to be imposed or any loss of income
         from such withdrawal to occur. If such a penalty would be imposed or
         any loss of income would occur if the investment were to be withdrawn,
         the payment of any amounts of the Escrow Money due to Sellers or to
         Purchaser shall be made as soon as practicable after the maturity date
         of the investment.

         4. Liability of Escrow Agent. Sellers and Purchaser agree that the
following provisions shall control with respect to the rights, duties,
liabilities, privileges and amenities of the Escrow Agent:

                  (a) The Escrow Agent is not a party to, and is not bound by,
         or charged with notice of, any agreement out of which this escrow may
         arise.

                  (b) The Escrow Agent acts hereunder as a depository only, and
         is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or depositing the escrow.

                  (c) The Escrow Agent shall be protected in acting upon any
         written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other paper or document which the
         Escrow Agent in good faith believes to be genuine and what it purports
         to be.

                  (d) Sellers and Purchaser, jointly and severally, agree to
         indemnify and hold the Escrow Agent harmless against any and all
         losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non-performance
         of its duties hereunder, excluding, however, any such liability
         resulting from its negligence, misconduct or breach of its
         instructions under this Agreement. In the event the Escrow Agent
         becomes involved in litigation in connection with this escrow, Sellers
         and Purchaser, jointly and severally, agree to indemnify and save the
         Escrow Agent harmless from any and all losses, claims, damages,
         liabilities and expenses, including attorney's fees and costs, which
         may be incurred or suffered by Escrow Agent as a result thereof,



                                       4
<PAGE>   82



         excluding, however, any such liability resulting from its negligence,
         misconduct, or breach of its instructions under this Agreement.

                  (e) In the event of any disagreement between any of the
         parties to this Agreement resulting in adverse claims or demands being
         made in connection with the Escrow Money, or in the event the Escrow
         Agent in good faith is in doubt as to what action it should take
         hereunder, the Escrow Agent may, at its option, refuse to comply
         with any claims or demands on it, or refuse to take any other action
         hereunder, so long as such disagreement continues or doubt exists, and
         in such event, the Escrow Agent shall not be or become liable in any
         way or to any person for its failure or refusal to act, and the Escrow
         Agent shall be entitled to continue to so refrain from acting until
         (i) the rights of all the parties shall have been fully and finally
         adjudicated by a court of competent jurisdiction, or (ii) all
         differences shall have been adjudicated and all doubt resolved by
         agreement among all the interested parties and the Escrow Agent shall
         have been notified thereof pursuant to written directions duly
         executed by all such persons.

         5. Compensation of Escrow Agent. The fee for the Escrow Agent in
connection with this Agreement shall be paid by Sellers out of interest earned
on the Escrow Money.

         6. Non-Waiver. Nothing contained in this Agreement shall be deemed or
construed to release or waive any of the rights or obligations of Purchaser or
Sellers under the Stock Purchase Agreement, and all rights and remedies of
Sellers and Purchaser under this Agreement are cumulative of all other rights
which either of them may have under the Stock Purchase Agreement, by law or
otherwise.

         7. Notices. Any notices, claims or demands which any party is required
or may desire to give to another under or in conjunction with this Agreement
shall be in writing, and shall be given by addressing the same to such other
party(ies) at the address set forth below, and by: (i) depositing the same so

by written notice delivered pursuant to the terms of this section.

         8. Entire Agreement; Amendments. This Agreement sets forth the entire
understanding of the parties and supersedes all prior agreements or
understandings, whether written or oral, with respect to the subject matter

and inure to the benefit of the parties hereto, their respective successors and
assigns.

         11. Waiver; Remedies. Waiver by any party hereto of any breach of or
exercise of any rights under this Agreement shall not be deemed to be a waiver
of similar or other breaches or rights or a future breach of the same duty. The
failure of a party to take any action by reason of any such breach or to
exercise any such right shall not deprive any party of the right to take any
action at any time while such breach or condition giving rise to such right
continues. The parties shall have all remedies permitted to them by this
Agreement or law, and all such remedies shall be cumulative.

         12. Attorney's Fees and Costs. In the event of a breach by any party
to this Agreement and commencement of a subsequent legal action in a court of
law or forum of arbitration, the prevailing party in any such dispute shall be
entitled to reimbursement of 



                                       6
<PAGE>   84



reasonable attorney's fees and court costs, including, but not limited to, the
costs of expert witnesses, transportation, lodging and meal costs of the
parties and witnesses, costs of transcript preparation and other reasonable and

                  a. the judgment or award against it is equal to or less than
         eighty percent (80%) of that party's written settlement offer; or

                  b. the judgment or award in its favor is equal to or greater
         than one hundred and twenty percent (120%) of that party's written
         settlement demand.

         costs incurred from a point in time commencing twenty (20) days after
         receipt of the offer or demand of settlement under (a) or (b) above.

                  Adjudication of a party's entitlement to counsel fees shall
         be by way of a non-jury proceeding following adjudication of the
         underlying claim.


         13. Termination. This Agreement shall terminate at such time as all of
the Escrow Money shall have been released in accordance with the terms and
conditions of this Agreement.

         14. Notification. Escrow Agent by Escrow Agent's execution
acknowledges that Escrow Agent has received notification of Purchaser's
interest in the Escrow Money.

         15. Resignation and Termination. The Escrow Agent may resign as such
by delivering written notice to that effect at least sixty (60) days prior to
the effective date of such resignation to Sellers and Purchaser. Upon
expiration of such sixty (60) day notice period, the Escrow Agent may deliver
the portion of the Escrow Money remaining in its possession to any successor
Escrow Agent appointed by Sellers and Purchaser pursuant to this Section 15 or,
if no successor Escrow Agent has been appointed, to any court of competent
jurisdiction in Phoenix, Arizona, or in accordance with the joint written
instructions of Purchaser and Sellers. Purchaser and Sellers, acting jointly,
may terminate the Escrow Agent from its position as such by delivering to the
Escrow Agent written notice to that effect executed by Purchaser and Sellers at
least thirty (30) days prior to the effective date of such termination. In the
event of such resignation or termination of the Escrow Agent, a successor
Escrow Agent shall be appointed by mutual agreement between Purchaser and
Sellers, and the Escrow Agent shall deliver the portion of the Escrow Money
remaining in its possession to such successor Escrow Agent. From and after the
appointment of a successor Escrow Agent pursuant to this Section 15, all
references herein to the Escrow Agent shall be deemed to be to such successor
Escrow Agent. The delivery by the Escrow Agent of the Escrow Money hereunder in
accordance with the provisions of this Section 15 shall constitute a full and
sufficient discharge and acquittance of the Escrow Agent in respect to such
sums delivered, and the Escrow Agent shall be entitled to receive releases and
discharges therefor. The indemnities in favor of the Escrow Agent 



                                       7
<PAGE>   85

contained in this Agreement and the obligations of Purchaser and Sellers under
Section 4 hereof shall survive for the benefit of the Escrow Agent after any
resignation or termination.

         16. Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                         EARNEST MONEY ESCROW AGREEMENT


         This Earnest Money Escrow Agreement (the "Agreement") is made as of
the 5th day of September, 1996 among Frank A. Pettisani, D.D.S., Lisa M.
Mazzone, Frank A. Pettisani, Jr., D.D.S., Charles A. Costa and Donna Costa
(referred to herein collectively as the "Sellers" and individually as a
"Seller"); United Dental Care, Inc., a Delaware corporation ("Purchaser"); and
Prudential Securities (the "Escrow Agent").

         WHEREAS, Sellers and Purchaser have entered into that certain Stock
Purchase Agreement dated September ____, 1996 (the "Stock Purchase Agreement")
providing for the purchase of all the issued and outstanding shares of capital
stock of OraCare Consultants, Inc., a New Jersey corporation (the "Company")
(the "Shares") from the Sellers by Purchaser; and

         WHEREAS, in connection with the execution of the Stock Purchase
Agreement, Purchaser has agreed to place the sum of Three Hundred Thousand and
no/100ths Dollars ($300,000.00) in escrow and for the purposes hereinafter set
forth.  (Such initial and additional escrow deposit and any interest earned
thereon while such funds are in escrow are referred to herein as the "Escrow
Money"); and

         WHEREAS, the parties desire to effectuate the provisions of the Stock
Purchase Agreement with respect to the Escrow Money;

         NOW, THEREFORE, IN CONSIDERATION OF THE PREMISES and the mutual terms
and conditions hereof, the parties hereby agree as follows:

         1.      Escrow Money.  Simultaneously with the execution of this
Agreement, Purchaser has deposited the sum of $300,000 with the Escrow Agent,
the receipt of which is hereby acknowledged by the Escrow Agent by its
execution hereof.

         2.      Escrow Account.  The Escrow Money shall be held in escrow by
the Escrow Agent pursuant to the terms and conditions of this Agreement.  Upon
receipt of the Escrow Money,  the Escrow Agent shall place the Escrow Money
deposit into an interest bearing account under the following terms and
conditions: (i) at Prudential Securities; (ii) under the name of the
OraCare-UDCI Earnest Money Escrow Account and (iii) under the federal tax
identification (ID) number of the Purchaser (#75-2309712).  It is understood
and agreed that the Escrow Agent will be issuing a 1099 INT statement to the
Purchaser and the Internal Revenue Service, even though the interest may be
payable eventually to either the Purchaser or the Sellers as the case may be.
In the event the interest is paid to the Purchaser, the Purchaser shall have
the responsibility as to any 1099 INT reporting thereof.  The Escrow Money
shall at all times be held in a separate account and shall only be delivered
pursuant to the terms and conditions of this Agreement.




                                      1
<PAGE>   2
         3.      Terms of Escrow.  The Escrow Money shall be held as a trust
deposit and shall be applied by the Escrow Agent in accordance with the
following terms and directions:

                 (a)      Application upon Closing.  In the event that the
         Sellers have not furnished written notice to Purchaser and the Escrow
         Agent of the failure of Purchaser to consummate the Stock Purchase
         Agreement in accordance with Section 3(b) below prior to Closing under
         the Stock Purchase Agreement, then, upon the Closing, Escrow Agent
         shall receive a notice executed by Purchaser and the Sellers directing
         Escrow Agent to either (i) pay the Escrow Money to Sellers as the
         notice shall direct in which case the initial $300,000 escrow deposit
         and any interest earned thereon shall constitute a credit against the
         Purchase Price or (ii) refund the Escrow Money to the Purchaser in
         which case it shall not constitute a credit against the Purchase
         Price.

                 (b)      Application upon Termination.  If Purchaser fails to
         consummate the Stock Purchase Agreement for any reason other than (i)
         a material breach of the Stock Purchase Agreement or this Agreement by
         Sellers or (ii) the valid exercise of any right of termination by
         Purchaser expressly set forth in the Stock Purchase Agreement, then
         the Sellers shall furnish written notice to Purchaser and the Escrow
         Agent of Purchaser's failure to consummate the Stock Purchase
         Agreement and directing that the Escrow Money be paid to the Sellers.
         Ten (10) days after such notice is received by Purchaser and the
         Escrow Agent as proven by cancellation marks on registered or
         certified mail return receipts, the Sellers shall be entitled to be
         paid the Escrow Money on pro rata basis determined according to the
         percentage of the Purchase Price under the Stock Purchase Agreement
         that would have been payable to the Sellers and the Escrow Agent shall
         release the Escrow Money to the Sellers on such pro rata basis.
         Otherwise, ten (10) days after receipt of written notice/demand from
         the Purchaser to the Sellers and the Escrow Agent that one of the
         conditions stated in (i) or (ii) above has occurred and that the
         Purchaser is entitled to receive a refund of the Escrow Money, as
         proven by cancellation marks on registered or certified mail return
         receipts, the Purchaser shall be entitled to be refunded the Escrow
         Money and the Escrow Agent shall release the Escrow Money to the
         Purchaser.

                 (c)      Automatic Termination.  In the event that the Escrow
         Agent has not received instructions as to the release of the Escrow
         Money before September 30, 1997, then this Escrow Agreement shall
         automatically terminate on September 30, 1997 and the Escrow Agent
         shall refund the Escrow Money to Purchaser without the necessity of
         any further notice or instructions of any kind.

                 (d)      Interest.  Interest earned on the Escrow Money shall
         be applied together with the Escrow Money and paid to the Sellers or
         to Purchaser as the case may be as specified above.

         4.      Liability of Escrow Agent.  Purchaser and Sellers hereby agree
that the following provisions shall control with respect to the rights, duties,
liabilities, privileges and amenities of the Escrow Agent:





                                       2
<PAGE>   3
                 (a)      The Escrow Agent is not a party to, and is not bound
         by, or charged with notice of, any agreement out of which this escrow
         may arise.

                 (b)      The Escrow Agent acts hereunder as a depository only,
         and is not responsible or liable in any manner whatsoever for the
         sufficiency, correctness, genuineness or validity of the subject
         matter of the escrow, or any part thereof, or for the form or
         execution thereof, or for the identity or authority of any person
         executing or deposition the escrow.

                 (c)      The Escrow Agent shall be protected in acting upon
         any written notice, request, waiver, consent, certificate, receipt,
         authorization, power of attorney, or other paper or document which the
         Escrow Agent in good faith believes to be genuine and what it purports
         to be.

                 (d)      Purchaser and the Sellers, jointly and severally,
         agree to indemnify and hold the Escrow Agent harmless against any and
         all losses, claims, demands, liabilities and expenses, including
         attorney's fees and costs, which may be incurred by the Escrow Agent
         in connection with the acceptance and performance or non- performance
         of its duties hereunder whether such losses, claims, demands,
         liabilities and expenses arise during or subsequent to performance of
         this Agreement, directly or indirectly, excluding, however, any such
         liability resulting from its negligence, misconduct, or breach of its
         instructions under this Agreement.  In the event the Escrow Agent
         becomes involved in litigation in connection with this escrow,
         Purchaser and the Sellers, jointly and severally, agree to indemnify
         and save the Escrow Agent harmless from any and all losses, claims,
         damages, liabilities and expenses, including attorney's fees and
         costs, interpleader costs and judgments, which may be incurred or
         suffered by Escrow Agent as a result thereof, excluding, however, any
         such liability resulting from its negligence, misconduct, or breach of
         its instructions under this Agreement.

                 (e)      In the event of any disagreement between any of the
         parties to this Agreement or with any third person resulting in
         adverse claims or demands being made in connection with the Escrow
         Money, or in the event the Escrow Agent in good faith is in doubt as
         to what action it should take hereunder, the Escrow Agent may, at its
         option, refuse to comply with any claims or demands on it, or refuse
         to take any other action hereunder, so long as such disagreement
         continues or doubt exists, and in such event, the Escrow Agent shall
         not be or become liable in any way or to any person for its failure or
         refusal to act, and the Escrow Agent shall be entitled to continue to

such time;

                 (o)      The Company will not make any change in any method of

Company shall make all filings, applications, statements and reports to all
governmental authorities which are required to be made prior to the Closing
Date by or on behalf of it pursuant to any applicable statute, rule or
regulation in connection with this Agreement and the transactions contemplated
hereby.  As required in connection with the performance of this Agreement by
the Company, the Company will promptly provide such other information and
communications to governmental and regulatory authorities, including, without
limitation, insurance regulatory authorities in any jurisdiction in which the
Company conducts business, as such regulatory authorities or Purchaser may
reasonably request.  Between the date hereof and the Closing Date, the Company
shall promptly provide Purchaser with copies of all correspondence and filings
to or from all governmental and regulatory bodies and officials relating to the
Company.

       5.7       Publicity.  Prior to the Closing, any public statement or

and approval prior to the release by the Company, and shall be released only in
a form approved by Purchaser, provided, however, that (i) such approval shall
not be unreasonably withheld and (ii) such review and approval shall not be
required of statements and announcements if prior review and approval would
prevent the timely and accurate dissemination of such statements and
announcements as required to comply, in the judgement of counsel, with any
applicable law, rule or policy.  Seller and Purchaser shall issue a press
release regarding the execution of this Agreement within one day of the date
hereof or such other time as Seller and Purchaser may mutually agree.

       5.8       Financial Information.  Seller will cause the Company to, and

and expenses of Counsel to Seller and other advisors or financial consultants
to the Seller incurred in connection with this Agreement and the consummation
of the transactions contemplated hereby; provided, however, that such costs and
expenses shall be included in determining the Net Income of the Company for the
purposes of Section 5.5(c) of this Agreement and provided further, however,
that neither the Company nor the Purchaser shall pay any such costs and
expenses incurred by Seller in connection with this Agreement after the
Closing.

       5.10      Breach of Representations and Warranties.  Promptly upon any
Seller or the Company becoming aware of any breach of any of the
representations and warranties of the Seller contained in this Agreement, or
any event which would cause the Seller to be unable to deliver the certificates
contemplated by Section 8.1(e) hereof, the Seller shall give written notice
thereof to the Purchaser in sufficient detail to permit the Purchaser to
ascertain the nature of the breach and shall use all commercially reasonable
efforts to prevent or promptly remedy the same.

       5.11      No Transfer of Shares.  Unless and until this Agreement is
terminated, Seller shall not, directly or indirectly, exchange, transfer,
assign, pledge or encumber any of the Shares owned by the Seller, nor shall a
Seller grant, directly or indirectly, any right to acquire, dispose of, vote or
otherwise control in any manner such Shares.

       5.12      Updating of Exhibits and Schedules.  Seller shall notify
Purchaser in writing of any changes, additions, or events which may cause any
change in or addition to the Schedules delivered by them under this Agreement
promptly after the occurrence of the same and again at the Closing by delivery
of appropriate updates to all such Schedules.  No notification of a change or
addition to a Schedule made pursuant to this Section shall be deemed to cure
any breach of any representation or warranty resulting from such change or
addition unless Purchaser specifically agrees thereto in writing, nor shall any
such notification be considered to constitute or give rise to a waiver by
Purchaser of any condition set forth in this Agreement; provided, however,
that, in the event Purchaser has actual knowledge of any misrepresentation or
breach of warranty at or prior to the Closing and nevertheless proceeds with
the Closing, then the





                                       21
<PAGE>   28
Purchaser shall be deemed to have waived such misrepresentation or breach of
warranty.  Nothing contained herein shall be deemed to create or impose on
Purchaser any duty to examine or investigate any matter or thing for the
purposes of verifying the representations and warranties made by Seller herein.

such filings and approvals.
     
       6.5       Confidentiality.  Prior to Closing, unless otherwise required 
by law, Purchaser will hold in confidence all confidential information that has
been disclosed by the Seller and the Company and will not use any such

Company shall have standing and may avail itself of any remedy at law or in
equity, including an action for injunctive relief, in the event of a breach or
threatened breach by Purchaser of any of the provisions of this Section 7.5.  
The obligations of Purchaser under this Section 7.5 shall survive termination

statements and announcements as requested to comply, in the judgment of
counsel, with any applicable law, rule or policy.  Seller and Purchasers shall
issue a press release regarding the execution and delivery of this Agreement
within one day after the date hereof or such other time as Seller and Purchaser

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       10.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
if, prior to the expiration of such two year period, a state of facts shall
have become known which threatens to give rise to a liability against which any
party hereto would be entitled to indemnification hereunder and the indemnified
party shall have given notice of such facts to the indemnifying party, then the
rights of the indemnified party to indemnification with respect to such
liability shall continue until such liability shall have been finally
determined and disposed of (including and subject to disposition by the
expiration of the applicable statute of limitations with respect to such
liability); provided further, however, that if a claim for indemnification is
made pursuant to this Article 11, then such claim for indemnification or any
claim arising out of the wrongful failure to comply with the provisions of this

to the extent provided otherwise in Section 11.4(c) below.  With respect to the
representations and warranties of the parties, such representations and
warranties shall be true as of and at the date of the Closing but nothing
contained herein shall be deemed to require or imply that the accuracy of such
representations and warranties shall apply on a continuing basis as to facts
existing after the date of the Closing.  Except to the extent set forth herein,
no investigation or examination made by any party hereto shall constitute a
waiver of any representation or warranty and no representation or warranty
shall be merged into the Closing hereunder.  However, to the extent information
is apparent on the face of the Schedules or is otherwise expressly set forth
herein, such information shall be deemed to amend, limit and/or restate any
representation and warranties contained herein to the extent such information
is inconsistent with such representation or warranty.

of any kind whatsoever, arising out of or resulting from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Seller at Closing hereunder;

                 (ii)     Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Seller are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 10.2(a) above; and

                 (iii)    Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       10.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
10.2(a) or 10.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might reasonably be expected to result in any
such claim, demand or action, such party shall promptly notify the other party
or parties who would be obligated to provide indemnity hereunder with respect
to such claim, demand or action, and such other party or parties shall have the
right to take such action as it or they may deem appropriate to resolve such
matter.  The indemnified party or parties shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties, unless the employment of such counsel





                                       29
<PAGE>   36
has been specifically authorized by the indemnifying party or parties.  Any
settlement of any action subject to indemnity hereunder shall require the
consent of the indemnified and the indemnifying party which consent shall not
be unreasonably withheld and shall be given within five (5) days following the
giving of notice thereof.  The indemnifying party or parties shall not be
liable for any settlement of any action effected without its or their consent,
but if settled with the consent of the indemnifying party or parties or if
there be a final judgment for the plaintiff in any such action, the
indemnifying party or parties shall indemnify and hold harmless the indemnified
party from and against any loss or liability by reason of such settlement or
judgment.  If requested by the indemnifying party, the indemnified party shall
cooperate with the indemnifying party and its counsel and use its best efforts
in contesting any such claim or, if appropriate, in making any counter-claim or
cross-complaint against the party asserting the claim, provided that the
indemnifying party will reimburse the indemnified party for reasonable
out-of-pocket expenses incurred in so cooperating upon presentation of receipts
or other evidence of such expense.  The indemnifying party and its
representatives shall have full and complete access during reasonable hours to
all books, records and files of the indemnified party expressly related to the
defense of any claim for indemnification undertaken by the indemnifying party
pursuant to this Article 10, or for any other purpose in connection therewith;
provided that the indemnifying party shall safeguard and maintain the
confidentiality of all such books, records and files.

       10.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Seller nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Seventy-Five
Thousand Dollars ($75,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms hereof; provided, however, that the
$75,000 limitation set forth in this Section 10.4(a) shall not apply to the
matters described in Section 10.4(c).  With respect to any indemnifiable loss
payable by the Seller, the funds in the Post- Closing Escrow Account shall be
used for such purpose first before any recovery is sought directly from a
Seller; provided, however, that to the extent the indemnification loss or
losses exceed the funds in the Post-Closing Escrow Account, then the Purchaser
may seek recovery of the amount of such indemnifiable loss in excess of such
funds contemporaneously with the recovery of any funds in the Post-Closing
Escrow Account.

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 10.1 and this Section 10.4(b) shall not apply
to the matters described in Section 10.4(c) not reasonably discoverable by
Seller within the two-year indemnification period set forth in Section 11.1 as
to which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party





                                       30
<PAGE>   37
shall have given notice of such facts to the indemnifying party and made a
claim for indemnification within such two-year period, then the right to
indemnification with respect thereto shall remain in effect until such matter
shall have been finally determined and disposed of and any indemnification due
in respect thereof shall have been paid.

                 (c)      Certain Matters.    The following are the matters 
referred to in Section 10.4(a) and Section 10.4(b):  Losses arising from fraud
or an intentional misrepresentation on the part of any Seller an intentional
breach of any covenant or agreement by a Seller contained in this Agreement.

       10.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Seller and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       10.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.  In
the event that the Purchaser shall elect to pay or cause the Company to pay any
severance benefits to employees of the Company who may be terminated at or
after the Closing, it is expressly understood that the Seller shall not be
entitled to receive such severance benefits.

and the Seller;

                 (b)      By Purchaser or Seller: Condition Precedent.  By
Purchaser or Seller, upon written notice to the other, if the conditions to the
obligations of such canceling party or parties to consummate the transaction,
in the case of the Seller, as provided in Article 8 or, in the case of
Purchaser, as provided in Article 9, were not, or cannot reasonably be,
satisfied on or before one hundred twenty (120) days after the date of this
Agreement unless the failure of the condition is the result of the material
breach of this Agreement by the party seeking to terminate; provided, however,
that, in the event all such conditions have been satisfied except solely the





                                       31
<PAGE>   38
condition with respect to obtaining all required consents, authorizations, and
approvals of governmental and regulatory agencies set forth in Sections 7.1(a)
and 8.1(a), respectively, and such failure is not due to a breach of this
Agreement by the non-terminating party, such date shall be automatically
extended for four (4) successive thirty (30) day periods so long as such
remains to be the case at the end of each respective thirty (30) day period
provided, however, that in no event shall such date be extended beyond an
aggregate of two hundred forty (240) days after the date of this Agreement
unless extended by the mutual agreement of the Purchaser and the Seller;

                 (c)      By Purchaser or Seller: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Seller, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) two hundred forty (240)
days after the date of this Agreement, unless such date is extended by mutual
agreement of Purchaser and Seller.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Seller,
Seller shall be entitled to retain the Earnest Money.  Any public announcement
of the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

       11.2      Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Seller, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

                                  ARBITRATION

       13.1      Arbitration Procedure.  Subject to the provisions of Section
13.7 below, in the event any matters in Dispute arising out of or relating to
this Agreement (including, but not limited to, actions for injunctive or
declaratory relief) (hereinafter collectively "arbitrable issues") cannot be
settled by agreement between the parties such controversy or dispute shall be
submitted for arbitration in Philadelphia, Pennsylvania, and for this purpose
each party hereby expressly consents to such arbitration in such forum.  The
arbitration process shall proceed as follows:

                 (a)      Step One.  In the event of a Dispute, the disputing
party (herein so called) may at any time notify the other party or parties
("answering party") in writing that the disputing party demands to pursue
arbitration as provided in Step Two below, setting forth in specific terms the
disputing party's proposed statement of the matters in Dispute to be submitted
to arbitration and the name and address of the arbitrator selected by the
disputing party.  Within five (5) business days following receipt of the
disputing party's written arbitration demand complying with the requirements of
this Step One, each answering party shall notify the disputing party in
writing, setting forth in specific terms the answering party's proposed
statement of the matter in Dispute and identifying the name and address of the
arbitrator selected by such answering party.  For purposes of this Section
15.1, all persons constituting the Sellers shall act as one party in selecting
an arbitrator, whether as a disputing party or as an answering party.

                 (b)      Step Two.  The two (2) or more arbitrators so
selected shall meet and confer within twenty (20) business days after receipt
by the disputing party of all of the answering parties' written notices as
called for under Step One above, and if they are unable within said twenty (20)
day period to reach a decision on the matters in Dispute, they shall, at the
expiration of said twenty (20) day period, jointly select a neutral arbitrator.
If said arbitrators are unable to choose a neutral arbitrator, any party may
request the AAA to appoint an additional arbitrator from its National Panel of
Commercial Arbitrators.  Any party to this Agreement may advise the AAA that
time is of the essence and that the parties to this Agreement would like such
selection as soon as is reasonably possible, it being expressly understood in
such AAA selection process that the selection is in the sole discretion of the
AAA, and that the AAA shall not be required by reason of this Agreement to
consult with the parties to this Agreement in said selection process; provided
that all arbitrators, including the additional arbitrator selected by the AAA,
shall be disinterested individuals knowledgeable in commercial transactions.
Upon selection of the additional arbitrator, all arbitrators shall within ten
(10) business days thereafter convene an arbitration proceeding at a date, time
and place (in metropolitan Philadelphia, Pennsylvania) designated by said
arbitrators by a majority vote, written notice of which shall be given to the
parties not later than seven (7) calendar days prior to said hearing date.  At
the hearing, each party may be represented by counsel and present testimony and
evidence.  If at the commencement of the hearing the parties cannot agree on a
joint statement of the matters in Dispute to be submitted to the arbitrators,
the arbitrators shall be empowered to frame the submission issue(s).  A
Certified Court Reporter's transcript may





                                       35
<PAGE>   42
be demanded by any party or by the arbitrators and said official transcript
shall be prepared, completed, and delivered to the arbitrators with copies to
each party within ten (10) business days following the conclusion of the
hearing.  Arbitration sessions following the initial session, if necessary,
shall be scheduled by the arbitrators so that the arbitration proceedings
(i.e., presentation of evidence and/or oral arguments) are completed within
twenty (20) days of the initial session.  Each party shall be given the
opportunity to file with the arbitrators simultaneous written briefs five (5)
business days following receipt by the arbitrators of the official transcript
but, if no transcript is demanded as provided in this Agreement, said briefs
shall be filed simultaneously five (5) business days following conclusion of
the hearing.  Copies of any such briefs shall be provided to the other party
concurrently upon filing with the arbitrators.

                 (c)      Step Three.  Within ten (10) business days following
the receipt by the arbitrators of the brief(s) (or within ten (10) business
days following conclusion of the hearing if all parties waive briefs), the
arbitrators shall make and deliver to the parties their decision and award in
writing.  The arbitrators shall have the authority to enter any award or to
grant any relief which could be obtained in a court of competent jurisdiction
and reasonable attorneys', arbitrators' and experts' fees and expenses of
arbitration may be awarded as the arbitrators see fit, consistent with the
provisions of this Agreement.  The arbitrators shall have no authority to
modify, amend or alter the provisions of this Agreement and shall base their
decision and award on applicable law, the language contained in this Agreement
and the facts giving rise to the Dispute as presented on the record at the
hearing.  The arbitrators shall issue a written opinion explaining the basis
for their findings.

       13.2      Self-Execution.  It is expressly understood between the
parties that this Article 13 is a self- executing arbitration provision and
that any party may unilaterally select an arbitrator if the other party refuses
to arbitrate.  It is further expressly agreed that said unilaterally-selected
arbitrator may proceed to arbitrate the issue(s) and the arbitration and
decision shall be self-executing and therefore shall not require the order of
any Court to proceed.  The parties may, however, mutually stipulate in writing
to extend or to shorten the prescribed time periods (including a stipulation to
expedite the referral and submission to arbitration).  All provisions of this
Agreement not in dispute shall be observed and performed without interruption
during the pendency of any proceeding called for under this Article 14.

       13.3      Arbitrator's Fees.  If an additional arbitrator is required
pursuant to Step Two under Section 13.1, each party shall pay its pr rata share
of any required retainer or other payments required by such arbitrator upon
such arbitrator's demand, with the ultimate responsibility for the arbitrators'
fees to be determined by the arbitrators in the final arbitration award
pursuant to Step Three of Section 13; otherwise, each party shall bear its own
costs and expenses in connection with any proceedings under this Article 13
and, in any event, each party shall pay the fees of the arbitrator it selects.

       13.4      Rules Governing Arbitration.  In all other respects, the
arbitration shall be conducted pursuant to the then-existing Commercial Rules
of the AAA to the extent such rules are not inconsistent with any provision of
this Agreement.  Subject to the foregoing, the arbitrators shall determine the
scope and extent of permissible discovery, if any.





                                       36
<PAGE>   43
       13.5      Entry of Award.  The award of the arbitrators may be entered
as a final judgment by any court of competent jurisdiction.

       13.6      Injunctive Relief.  Notwithstanding the provisions of this
Article 13 to the contrary, each party shall be entitled to seek temporary or
preliminary injunctive relief from a court of competent jurisdiction if the
failure to immediately obtain injunctive relief will result in irreparable harm
to that party.  The jurisdiction of the court shall extend only to such relief
and any request for permanent injunctive relief shall remain subject to the
arbitration provisions of this Agreement.

       13.7      Non-Applicability to Note.  Notwithstanding any provision of
this Article 13 to the contrary, the provisions of this Article 13 shall
expressly not apply to any dispute arising out or relating to the Note.

                                 MISCELLANEOUS

deliver such instruments and take such other action as shall be reasonably
necessary, or as shall be reasonably requested by any other party, in order to
carry out the transactions, agreements and covenants contemplated in this
Agreement at or prior to the Closing Date.

       14.2      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to
such other party(ies) at the address set forth below, and by (i) depositing the

facsimile, the day of transmission if made within customary business hours, or

       14.4      Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any affiliate of
Purchaser without the necessity of seeking the consent of the Seller; provided,
however, that Purchaser shall not be relieved of any obligations as a result of
such assignment and that, in addition to Purchaser remaining liable, any such
assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  Seller acknowledges that Purchaser intends
to assign its rights under this Agreement to an individual licensed under New
York law to practice dentistry on or prior to the Closing.  The Seller shall
not be entitled to assign any of his rights or obligations under this
Agreement; provided, however, that the rights and obligations of the Seller may
be assigned by operation of law or may be assigned to an





                                       38
<PAGE>   45
individual retirement account, pension plan, trust or other entity under the
control of the Seller but any such assignment shall not relieve or release such
Seller of any obligations hereunder as a result of such assignment and that, in
addition to such Seller remaining liable, any such assignee shall assume and
become liable for any and all of such Seller's obligations under this
Agreement. In connection with any such assignment, a Seller may transfer all or
any portion of the Shares owned by the Seller and thereby effect an assignment
on the basis specified above.

       14.5      Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

       14.7      Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

       14.8      Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

       14.9      Attorney's Fees and Costs.  In the event of a breach by any
party to this Agreement and commencement of a subsequent legal action in a
court of law or forum of arbitration, or in the event legal counsel is
consulted in the event of any such breach or in anticipation of any such
prospective legal action, the prevailing party in any such dispute shall be
entitled to reimbursement of reasonable attorney's fees and court costs,
including, but not limited to, the costs of expert witnesses, transportation,
lodging and meal costs of the parties and witnesses, costs of transcript
preparation and other reasonable and necessary direct and incidental costs of
such dispute.  A party shall be deemed to be a "prevailing party" under this
Section only if:

                 (a)      the judgment or award against it is equal to or less
than eighty percent (80%) of that party's written settlement offer; or,





                                       39
<PAGE>   46
                 (b)      the judgment or award in its favor is equal to or
greater than one hundred and twenty percent (120%) of that party's written
settlement demand.

The party responsible for attorneys' fees and costs under this provision shall
only be responsible for those attorney's fees and costs incurred from a point
in time commencing twenty (20) days after receipt of the offer or demand of
settlement under (a) or (b) above.  Adjudication of a party's entitlement to
counsel fees shall be by way of a non-jury proceeding following adjudication of
the underlying claim.

       14.10     Time.  Time is of the essence under this Agreement.

       14.11     Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
New Jersey.

       14.12     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

Company with a certificate of such insurance and all renewals thereof.

         8. Confidentiality/Trade Secrets. The Dentist acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and thereafter, the Dentist
covenants and agrees as follows:

                  (a) that he shall use his best efforts and exercise utmost
         diligence to protect and safeguard the trade secrets and confidential
         and proprietary information of the Company including but not limited
         to the identity of its customers and suppliers, its arrangements with
         customers and suppliers, and its technical data, records, compilations
         of information, processes, and specifications relating to its
         customers, suppliers, products and services;

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Dentist or otherwise coming into his possession, shall be the
exclusive property of the Company and shall



                                       2
<PAGE>   50



be delivered to the Company and not retained by the Dentist upon termination of
his employment for any reason whatsoever or at any other time upon request of
the Board.

         Provided, however, that "confidential information" shall not include
information regarding customers, suppliers, technical data, processes and
specifications which are generally known in the industry or are already in the
public domain other than through a breach of this provision by Executive or
another person in violation of a duty of confidentiality owed to the Company.

         9. Non-Competition. The Dentist covenants and agrees that, during the
period of his employment, and so long as any severance payments are being made
hereunder, he shall not, without the prior written consent of the Board,
directly or indirectly, as an employee, employer, consultant, agent, principal,
partner, shareholder, corporate officer, director, or through any other kind of
ownership (other than ownership of securities of publicly held corporations of
which the Dentist owns less than two percent (2%) of any class of outstanding
securities) or in any other representative or individual capacity, engage in
any business or render any services to any business that is in competition in
any manner whatsoever with the business of the Company.

         10. Remedies for Breach of Covenants of the Dentist. The covenants set
forth in Paragraphs 8 and 9 of this Agreement shall continue to be binding upon
the Dentist, notwithstanding the termination of his employment with the Company
for any reason whatsoever. Such covenants shall be deemed and construed as
separate agreements independent of any other provisions of this Agreement and
any other agreement between the Company and the Dentist. The existence of any
claim or cause of action by the Dentist against the Company, whether predicated
on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of any or all of such covenants. It is expressly
agreed that the remedy at law for the breach of any such covenant is inadequate
and the injunctive relief shall be available to prevent to the breach or any
threatened breach thereof.

         11. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Dentist may terminate this Agreement and
         his employment at any time during the term of this Agreement by giving
         ninety (90) days prior written notice of termination to the Board.

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon ninety (90) days prior written notice to the Dentist.

         notice effective immediately, terminate this Agreement at any time
         during the term of this Agreement if any one of the following
         conditions exist:



                                       3
<PAGE>   51



                           (1) If the Dentist becomes disabled for a period of
                  more than thirty (30) consecutive days;

                           (2) If the Dentist for reasons other than illness or
                  injury absents himself from his duties without the consent of
                  the Board for more than ten (10) consecutive days;

                           (3) If the Dentist should die (effective on the date
                  of death);

                           (4) If the Dentist should be convicted of a crime
                  punishable by imprisonment;

                           (5) If the Dentist should willfully breach or
                  habitually neglect his duties which he is required to perform
                  under this Agreement or otherwise fail to comply with the
                  terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in
                  Paragraphs 8 and 9 hereof; and

                           (6) The license to practice dentistry of the Dentist
                  is limited, suspended or revoked; and

                           (7) The Dentist is subject to any final adverse
                  disciplinary action by any dental board or similar body
                  licensing the Dentist on any grounds, including, but not
                  limited to, improper dental practices or improper conduct.

In the event of the termination of this Agreement by either party prior to the
expiration of the term of this Agreement, the Dentist shall be entitled to
compensation earned by him prior to the date of termination as provided herein.
In addition, in the event that the Company terminates this Agreement without
cause under Section 11(b) above, then the Dentists shall be entitled to be paid
a severance payment as liquidated damages for, and in lieu of, any and all
damages which he may suffer as a result of such termination an amount equal to
the average of the amount of monthly compensation that the Dentist earned in
the three calendar months prior to the date of termination times the number of
months remaining on the term of this Agreement after the month in which
termination occurs. Such payment shall be paid in installments payable on the
same dates on which payments would otherwise have been paid under this
Agreement. In addition, the Company shall continue the health benefits of the
Dentist during the period such severance payments are being made. The Dentist
shall be entitled to no further compensation as of the date of termination
under this Agreement. Any termination of this Agreement shall be without
prejudice to any right or remedy to which the terminating party may be entitled
either at law, in equity, or under this Agreement.

         This Employment Agreement (this "Agreement") is made as of __________,
1996 (the "Effective Date"), by and between OraCare Dental Associates, P.A., a
New Jersey professional association acting by and through its hereunto duly
authorized officer (the "Company"), and Frank A. Pettisani, Jr., D.D.S. (the
"Dentist").

         WHEREAS, The Company desires to employ the Dentist and the Dentist is
willing to render his services to the Company on the terms and conditions with
respect to such employment hereinafter set forth;

         NOW, THEREFORE, in consideration of premises and the mutual terms and
conditions hereof, the Company and the Dentist hereby agree as follows:

         1. Employment. The Company hereby employs the Dentist and the Dentist
hereby accepts employment with the Company upon the terms and conditions
hereinafter set forth.

         2. Exclusive Services. The Dentist shall devote his full working time,
ability and attention exclusively to the business of the Company during the
term of this Agreement and shall not, directly or indirectly, render any
services of a business, commercial or professional nature to any other person,
corporation or organization whether for compensation or otherwise, without the
prior knowledge and consent of the Board of Directors of the Company.

         3. Duties. The Dentist is hereby employed as a general dentist and as
the Dental Director of the Atlantic City Dental Clinic operated by the Company.
The Dentist shall render his services at such dental clinic of the Company
unless otherwise agreed between the Board of Directors of the Company (the

         4. Term. This Agreement shall have a term commencing as of the
Effective Date and ending December 31, 1998, subject to earlier termination as
hereinafter provided.

         5. Compensation. As compensation for his services rendered under this

                  (a) Basic Salary. The Dentist shall initially be paid a base
         annual salary of One-Hundred Thousand and No/100 Dollars ($100,000)

                  (b) Incentive Bonus. The Executive shall also be entitled to
         an incentive bonus on the following basis:

                           (i) The Dentist shall also be entitled to receive an
                  annual incentive bonus up to a maximum of $20,000 based on
                  the profits of the dental clinic of which the Dentist is the
                  dental director. In the event that the profits of such dental
                  clinic for a calendar year (as determined in accordance with
                  generally accepted accounting principles) exceed 125% of the
                  profits of such dental clinic for the prior calendar year,
                  then the incentive bonus shall be $20,000. If such profits
                  exceed 110% but less than 125% of the profits of such dental
                  clinic for the prior calendar year, then the incentive bonus
                  shall be prorated on the basis that $10,000 shall be paid at
                  a 110% increase and the balance up to an additional $10,000
                  based on the percentage over 110% that such profits exceeded
                  the profits for the prior year up to 125%. No incentive bonus
                  shall be payable if such profits do not exceed the profits
                  for the prior year by 110%.

                           (ii) Such bonus shall be payable on March 31 of the
                  year following the calendar year to which the bonus relates.

                  (c) Additional Compensation. The Dentist shall be paid such
         additional compensation and bonuses, if any, as may be determined in
         the sole discretion of the Board.

         6. Benefits. In addition to the compensation to be paid to the Dentist
pursuant to Paragraph 5 hereof, the Dentist shall further be included in any
hospital, surgical, and medical benefit plan, any group term life insurance
policy, any pension or profit sharing plan, and all other benefits which may be
extended from time to time to dentist employees of the Company generally by the
Board in its sole discretion.

         7. Reimbursement of Expenses. Subject to such rules and procedures as
from time to time are specified by the Company acting by and through the
President of the Company and/or the Board, the Company shall reimburse the
Dentist on a monthly basis for reasonable business expenses necessarily
incurred in the performance of his duties under this Agreement.

         8. Confidentiality/Trade Secrets. The Dentist acknowledges that his
position with the Company is one of the highest trust and confidence both by
reason of his position and by reason of his access to and contact with the
trade secrets and confidential and proprietary business information of the
Company. Both during the term of this Agreement and thereafter, the Dentist
covenants and agrees as follows:

                  (a) that he shall use his best efforts and exercise utmost
         diligence to protect and safeguard the trade secrets and confidential
         and proprietary information of the Company including but not limited
         to the identity of its customers and suppliers, its arrangements with
         customers and suppliers, and its



                                       2
<PAGE>   57


         technical data, records, compilations of information, processes, and
         specifications relating to its customers, suppliers, products and
         services;

                  (b) that he shall not disclose any of such trade secrets and
         confidential and proprietary information, except as may be required in
         the course of his employment; and

                  (c) that he shall not use, directly or indirectly, for his
         own benefit or for the benefit of another, any of such trade secrets
         and confidential and proprietary information.

         All files, records, documents, drawings, specifications, memoranda,
notes, or other documents relating to the business of the Company, whether
prepared by the Dentist or otherwise coming into his possession, shall be the
exclusive property of the Company and shall be delivered to the Company and not
retained by the Dentist upon termination of his employment for any reason
whatsoever or at any other time upon request of the Board.

         Provided, however, that "confidential information" shall not include
information regarding customers, suppliers, technical data, processes and
specifications which are generally known in the industry or are already in the
public domain other than through a breach of this provision by Executive or
another person in violation of a duty of confidentiality owed to the Company.

         9. Non-Competition. The Dentist covenants and agrees that, during the
period of his employment, and so long as any severance payments are being made
hereunder, he shall not, without the prior written consent of the Board,
directly or indirectly, as an employee, employer, consultant, agent, principal,
partner, shareholder, corporate officer, director, or through any other kind of
ownership (other than ownership of securities of publicly held corporations of
which the Dentist owns less than two percent (2%) of any class of outstanding
securities) or in any other representative or individual capacity, engage in
any business or render any services to any business that is in competition in
any manner whatsoever with the business of the Company.

         10. Remedies for Breach of Covenants of the Dentist. The covenants set
forth in Paragraphs 8 and 9 of this Agreement shall continue to be binding upon
the Dentist, notwithstanding the termination of his employment with the Company
for any reason whatsoever. Such covenants shall be deemed and construed as
separate agreements independent of any other provisions of this Agreement and
any other agreement between the Company and the Dentist. The existence of any
claim or cause of action by the Dentist against the Company, whether predicated
on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of any or all of such covenants. It is expressly
agreed that the remedy at law for the breach of any such covenant is inadequate
and the injunctive relief shall be available to prevent to the breach or any
threatened breach thereof.

         11. Professional Liability Insurance. During the term of employment,
the Dentist shall maintain professional liability insurance having limits of
$1,000,000 per occurrence/$3,000,000 aggregate. The Dentist shall provide the
Company with a certificate of such insurance and all renewals thereof.

         12. Termination. This Agreement may be terminated upon the occurrence
of any one of the following events:

                  (a) Voluntary. The Dentist may terminate this Agreement and

                  (b) Involuntary Without Cause. The Board, without cause, may
         terminate this Agreement at any time during the term of this Agreement
         upon ninety (90) days prior written notice to the Dentist.

                  (c) Involuntary with Cause. The Board may, upon written

         during the term of this Agreement if any one of the following
         conditions exist:

                           (1) If the Dentist becomes disabled for a period of
                  more than thirty (30) consecutive days;

                           (2) If the Dentist for reasons other than illness or
                  injury absents himself from his duties without the consent of
                  the Board for more than ten (10) consecutive days;

                           (3) If the Dentist should die (effective on the date

                           (5) If the Dentist should willfully breach or
                  habitually neglect his duties which he is required to perform
                  under this Agreement or otherwise fail to comply with the
                  terms and conditions of this Agreement specifically
                  including, but not limited to, the covenants set forth in

         construed in accordance with the laws of the State of New Jersey.

                  (b) Invalid Provisions. If any provision of this Agreement is
         held to be illegal, invalid, or unenforceable under present or future

         provision there shall be added automatically as a part of this

                  (e) Waiver. The waiver by either party hereto of a breach of

         construed as a waiver of a subsequent breach of the same provision by
         any party or of the breach of any other term or provision of this
         Agreement.

                  (f) Titles. Titles of the paragraphs herein are used solely
         for convenience and shall not be used for interpretation or construing

the Sellers, threatened governmental investigations by any federal, state or
local government or any subdivision thereof or by any public or private group

requirements or which would have the effect of limiting, prohibiting or
changing the business operations of the Company as authorized by the
authorizations, certificates of authority, licenses and permits set forth on
Schedule 4.5 and as presently conducted by the Company.  The Company maintains
statutory reserves that satisfy the requirements of all applicable governmental

<PAGE>   12
insurance or other similar law or received any request for information, notice,
demand letter, administrative inquiry or formal or informal complaint or claim
with respect to any insurance or other similar law or the enforcement of any
such law.  Neither the Company's operations nor any of the assets owned,
leased, occupied or used by the Company in the operation of its business

applicable federal, state or local insurance, health maintenance organization,
or prepaid dental plan codes, laws, rules or regulations or, to the knowledge
of Sellers, federal, state or local health, fire, environmental, safety,
zoning, building or other codes, laws, rules or regulations, and the Company

       4.6       Financial Statements.  The Company has delivered to Purchaser
a copy of (i) the unaudited financial statements of the Company as of December
31, 1993, 1994 and 1995 consisting in each case of a balance sheet at each such
respective date, and the related statements of income, changes in stockholders'
equity and cash flows for the applicable twelve (12) month period then ended
and (ii) unaudited financial statements of the Company as of June 30, 1996 (the
"Balance Sheet Date") consisting of a consolidated balance sheet of the Company

income, changes in stockholders' equity and cash flows for the applicable month
and year-to-date period then ended.  Complete and accurate copies of all such
financial statements have been delivered to Purchaser (the "Financial
Statements").  The Financial Statements present fairly in all material respects
the financial position of the Company, and the results of the operations,
changes in stockholders' equity and cash flows of the Company, as of the
respective dates thereof and for the respective periods covered thereby, in
conformity with generally accepted accounting principles ("GAAP").  Except as
set forth in the Company Balance Sheet included in the Financial Statements, as
of the Balance Sheet Date there were no liabilities, debts, claims or
obligations, whether accrued, absolute, contingent or otherwise, whether due or
to become due, which are required by GAAP to be set forth in a balance sheet of
the Company which have not been so set forth in the Company Balance Sheet.  The
Financial Statements were prepared from the books and records of the Company.
There are no assets shown on the Company Balance Sheet which are valued thereon
at an amount materially in excess of their fair value as of the Balance Sheet
Date.  At the Balance Sheet Date, the Company owned each of the assets included
in the Company Balance Sheet.  From the date hereof through the Closing Date,
the Company will continue to prepare monthly and year-to-date unaudited
financial statements on the same basis and will promptly deliver the same to
Purchaser.  The foregoing representations will be applicable to all such
monthly unaudited financial statements so prepared and delivered; provided,
however, that such unaudited financial statements shall be subject to normal
year-end adjustments, none of which will be material.

       4.7       No Adverse Change.  Except as otherwise expressly contemplated
by this Agreement, since the Balance Sheet Date, the business of the Company
has been conducted only in the ordinary course and there has not been (i) any
material adverse change in the financial condition, business, properties,
assets, or results of operations of the Company (financial or otherwise)
exclusive of any general economic factors affecting the prepaid dental plan
industry in general; (ii) any material loss or damage (whether or not covered
by insurance) to any of the assets of the Company which materially affects or
impairs the ability of the Company to conduct





                                       6
<PAGE>   13
its business as previously conducted or any other event or condition of any
character which has materially and adversely affected the business or
operations of the Company; (iii) the attaching, placing or granting of, or the
agreement to attach, place or grant, any encumbrance on any of the assets of
the Company; (iv) any sale or transfer of any material portion of the assets of
the Company; (v) any material changes in the terms of any material contract of
the Company; (vi) any material change in the accounting systems, policies or
practices of the Company; (vii) any waiver by or on behalf of the Company of
any rights which have any material value; (viii) no taking under condemnation
or right of eminent domain of any of the assets of the Company; (ix) any entry
into or termination of any material commitment, contract, agreement, or
transaction (including, without limitation, any material borrowing or capital
expenditure or sale or other disposition of any material assets) by the
Company; (x) any redemption, repurchase, or other acquisition of any of its
capital stock by the Company, or any issuance of capital stock of the Company
or of securities convertible into or rights to acquire any such capital stock;
(xi) any dividend or distribution declared, set aside or paid on capital stock
of the Company; (xii) any transfer or right granted by the Company of or under
any material lease, license, agreement, patent, trademark, trade name, service
mark or copyright; (xiii) any sale or other disposition of any material asset
of the Company, or any mortgage, pledge, or imposition of any lien or other
encumbrance on any material asset of the Company, or any agreement relating to
or contemplating any of the foregoing not in the ordinary and usual course of
business; (xiv) any default or breach by the Company in any material respect
under any contract, license, or permit; or (xv) any material increase in the
statutory reserves required to be maintained by the Company.  Except as set
forth on Schedule 3.10, since the Balance Sheet Date, the Company has conducted
its business only in the ordinary and usual course of business and, without
limiting the foregoing, no changes have been made in (i) employee compensation
levels other than usual and customary annual adjustments, (ii) the manner in
which employees of the Company are compensated, (iii) supplemental benefits

obligations hereunder, do not (i) conflict with, and will not result in a
breach of, any of the provisions of the certificate of incorporation or bylaws
of Purchaser; (ii) contravene any law, rule, or regulation of any State or

afford, and the Company shall afford, to Purchaser and its representatives
reasonable access during reasonable hours throughout the period prior to the

Purchaser immediately upon receipt of any offer or proposal relating to any of
the foregoing and such notice shall describe in detail the terms thereof and
identify the party or parties thereto.  From the date of this Agreement, until
the Closing or the termination of this Agreement pursuant to its terms, neither
the Company nor any of the Sellers will furnish, without the prior written
consent of Purchaser, to any person or entity (other than Purchaser) any
non-public information concerning the Company or its businesses, financial
affairs or prospects for the purpose of or with the intent of permitting such

or terminate any material contract or release or assign any material rights or
claims;

                 (j)      In connection with any filings to be made by the
Purchaser under the Securities Act of 1933, as amended, the Company shall (i)
provide for inclusion therein the financial and other information and documents

than that presently in effect;

                 (n)      The Company will not knowingly take any action (or

                 (o)      The Company will not make any change in any method of

The Company shall make all filings, applications, statements and reports to all
governmental authorities which are required to be made prior to the Closing
Date by or on behalf of it pursuant to any applicable statute, rule or
regulation in connection with this Agreement and the transactions contemplated
hereby.  As required in connection with the performance of this Agreement by
the Company, the Company will promptly provide such other information and
communications to governmental and regulatory authorities, including, without
limitation, insurance regulatory authorities in any jurisdiction in which the
Company conducts business, as such regulatory authorities or Purchaser may
reasonably request.  Between the date hereof and the Closing Date, the Company
shall promptly provide Purchaser with copies of all correspondence and filings
to or from all governmental and regulatory bodies and officials relating to the
Company.

       6.7       Publicity.  Prior to the Closing, any public statement or
announcement by the Sellers or Company, including but not limited to any
written news releases, pertaining to this Agreement or the transactions
contemplated thereby shall be submitted to Purchaser for review and approval
prior to the release by the Company, and shall be released only in a form
approved by Purchaser, provided, however, that (i) such approval shall not be
unreasonably withheld and (ii) such review and approval shall not be required
of statements and announcements if prior review and approval would prevent the
timely and accurate dissemination of such statements and announcements as
required to comply, in the judgement of counsel, with any applicable law, rule
or policy.  Sellers and Purchaser shall issue a press release regarding the
execution of this Agreement within one day of the date hereof or such other
time as Sellers and Purchaser may mutually agree.

       6.8       Financial Information.  Sellers will cause the Company to, and
the Company will, deliver as soon as reasonably practicable to Purchaser
unaudited financial statements of the Company for each month from and after the
date hereof as and when such financial statements become available in the usual
course of business.

       6.9       Expenses.  The Company may pay prior to the Closing the fees
and expenses of Counsel to Sellers and other advisors or financial consultants
to the Sellers incurred in connection with this Agreement and the consummation
of the transactions contemplated hereby; provided, however, that such costs and
expenses shall be included in determining the Net Income of the Company for the

that neither the Company nor the Purchaser shall pay any such costs and
expenses incurred by Sellers in connection with this Agreement after the
Closing.

       6.10      Breach of Representations and Warranties.  Promptly upon any
Sellers or the Company becoming aware of any breach of any of the
representations and warranties of the Sellers contained in this Agreement, or
any event which would cause the Sellers to be unable to deliver the
certificates contemplated by Section 8.1(e) hereof, the Sellers shall give
written notice thereof to the Purchaser in sufficient detail to permit the
Purchaser to ascertain the nature of the breach and shall use all commercially
reasonable efforts to prevent or promptly remedy the same.

<PAGE>   28

terminated, Sellers shall not, directly or indirectly, exchange, transfer,

Sellers grant, directly or indirectly, any right to acquire, dispose of, vote
or otherwise control in any manner such Shares.

       6.12      Updating of Exhibits and Schedules.  Sellers shall notify
Purchaser in writing of any changes, additions, or events which may cause any
change in or addition to the Schedules delivered by them under this Agreement
promptly after the occurrence of the same and again at the Closing by delivery
of appropriate updates to all such Schedules.  No notification of a change or
addition to a Schedule made pursuant to this Section shall be deemed to cure
any breach of any representation or warranty resulting from such change or
addition unless Purchaser specifically agrees thereto in writing, nor shall any
such notification be considered to constitute or give rise to a waiver by
Purchaser of any condition set forth in this Agreement; provided, however,
that, in the event Purchaser has actual knowledge of any misrepresentation or
breach of warranty at or prior to the Closing and nevertheless proceeds with
the Closing, then the Purchaser shall be deemed to have waived such
misrepresentation or breach of warranty.  Nothing contained herein shall be
deemed to create or impose on Purchaser any duty to examine or investigate any
matter or thing for the purposes of verifying the representations and
warranties made by Sellers herein.

<PAGE>   29
such governmental regulatory consents other than normal and customary filing
fees and out-of-pocket costs and expenses of the Company incurred in providing
its assistance with respect thereto.  Purchaser shall diligently and promptly
proceed immediately after the date of this Agreement to make all filings,
applications, statements and reports to all governmental authorities which are

any jurisdiction in which the Company conducts business, as such regulatory
authorities may reasonably request.  Purchaser shall not be required to cure
any existing regulatory compliance requirements in order to obtain such
consents and approvals.  Within five (5) business days after the written
request of the Sellers, the Purchaser shall provide to the Sellers a status
report as to all such filings and approvals.

       7.5       Confidentiality.  Prior to Closing, unless otherwise required
by law, Purchaser will hold in confidence all confidential information that has
been disclosed by the Sellers and the Company and will not use any such
confidential information except in connection with the transaction, until such
time as such information is otherwise publicly available through sources other
than Purchaser; provided, however, that this sentence will not apply to any
information that becomes generally available to the public, was available on a
non-confidential basis to Purchaser prior to its disclosure pursuant hereto, or
becomes available on a non-confidential basis from a third party who is not
bound to keep such information confidential.  In the event of the termination
of this Agreement, Purchaser will, and will cause its representatives to,
deliver to the Company all documents and other written materials, and all
copies thereof, obtained by Purchaser or on its behalf from the Sellers or the
Company as a result of this Agreement or in connection herewith, whether so

Company shall have standing and may avail itself of any remedy at law or in
equity, including an action for injunctive relief, in the event of a breach or
threatened breach by Purchaser of any of the provisions of this Section 8.5.
The obligations of Purchaser under this Section 7.5 shall survive termination

releases by the Purchaser, pertaining to this Agreement or the transactions
contemplated hereby shall be submitted to the Company for review and approval
prior to the release by the Purchaser, and shall be released only in a form
reasonably approved by the Company provided however, that (i) such approval

and approval would prevent the timely and accurate dissemination of such
statements and announcements as requested to comply, in the judgment of
counsel, with any applicable law, rule or policy.  Sellers and Purchasers shall
issue

                 (e)      Purchaser shall have received from Sellers a

the Company; including, without limitation, the following which shall be
considered a material adverse change, to-wit:

       than $100,000.00 (including attorneys' fees for defending such claim) in
       excess of insurance coverage maintained by the Company which would be
       applicable to such claim; provided, however, that, in the event that the
       parties cannot mutually agree as to whether any such litigation or claim
       is reasonably expected to have such potential liability to the Company,
       then the parties shall seek the opinion of a mutually selected third
       party qualified to make such assessment and the opinion of such third
       party as to such potential liability shall be binding upon the parties
       for the purposes hereof;

                 (h)      At or prior to Closing, the Company shall have
received (and delivered copies thereof to Purchaser) duly executed resignation

amounts due from the Company to such respective individuals except as expressly
set forth in this Agreement.

                 (i)      At the Closing, the Sellers shall execute a release

                          SURVIVAL OF REPRESENTATIONS
                AND WARRANTIES; INDEMNITY; POST-CLOSING MATTERS

       11.1      Representations and Warranties to Survive.  All statements
contained in any agreement, certificate, instrument, schedule, or document
delivered by or on behalf of any of the parties pursuant to this Agreement and
the transactions contemplated hereby shall be deemed representations and
warranties by the delivering party hereunder.  All representations, warranties,
covenants and agreements made by the parties each to the other in this
Agreement shall be true at the Closing and shall survive the consummation of
this Agreement and the Closing hereunder for a period of two years, ending at
midnight on the second anniversary of the Closing Date; provided, however, that
if, prior to the expiration of such two year period, a state of facts shall
have become known which threatens to give rise to a liability against which any
party hereto would be entitled to indemnification hereunder and the indemnified
party shall have given notice of such facts to the indemnifying party, then the
rights of the indemnified party to indemnification with respect to such
liability shall continue until such liability shall have been finally
determined and disposed of (including and subject to disposition by the
expiration of the applicable statute of limitations with respect to such
liability); provided further, however, that if a claim for indemnification is
made pursuant to this Article 11, then such claim for indemnification or any
claim arising out of the wrongful failure to comply with the provisions of this
Article 11 shall survive until the expiration of the applicable period of
limitations with respect to such claim for indemnification; and provided
further, however, that such two year limitation specified above shall not apply
to the extent provided otherwise in Section 11.4(c) below.  With respect to the
representations and warranties of the parties, such representations and
warranties shall be true as of and at the date of the Closing but nothing
contained herein shall be deemed to require or imply that the accuracy of such
representations and warranties shall apply on a continuing basis as to facts
existing after the date of the Closing.  Except to the extent set forth herein,
no investigation or examination made by any party hereto shall constitute a
waiver of any representation or warranty and no representation or warranty
shall be merged into the Closing hereunder.  However, to the extent information
is apparent on the face of the Schedules or is otherwise expressly set forth
herein, such information shall be deemed to amend, limit and/or restate any
representation and warranties contained herein to the extent such information
is inconsistent with such representation or warranty.

       11.2      Indemnity.  Subject to the provisions of Section 11.4 below,

                 (a)      Sellers.  Sellers agrees to indemnify and hold
harmless the Company, each Subsidiary, and Purchaser, and their respective
shareholders, partners, directors, officers, employees and agents, from,
against, and in respect of, any loss, liability, claim, demand, or expense,
including but not limited to reasonable attorney, investigation and consultant
fees and costs, and of any other kind whatsoever arising out of or resulting
from any of the following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of the Sellers and the Company
       under this Agreement or under any other agreement or document delivered
       by the Sellers at Closing hereunder; and

                 (ii)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs and legal and other expenses incident to
       any of the foregoing.

                 (b)      Purchaser.  Purchaser shall indemnify and hold
Sellers harmless from, against, and in respect of, any loss, liability, claim,
demand, or expense, including but not limited to reasonable attorney's fees and
costs, of any kind whatsoever, arising out of or resulting from any of the
following:

                 (i)      Any misrepresentation, breach of warranty, or failure
       to fulfill any agreement or covenant of Purchaser under this Agreement
       or under any other agreement or document delivered by Purchaser to
       Sellers at Closing hereunder;

                 (ii)     Any obligation or liability of the Company, whether
       arising out of any set of facts in existence before, on or after the
       Closing Date; excluding, however, any obligation or liability with
       respect to which the Sellers are obligated to indemnify and hold the
       Purchaser harmless pursuant to Section 11.2(a) above; and

                 (iii)     Any and all actions, suits, proceedings, demands,
       assessments, judgments, costs, and legal and other expenses incident to
       any of the foregoing.

       11.3      Indemnity Procedures.  In case any claim, demand or action
shall be brought by any third party including, without limitation, any
governmental authority, against a party entitled to indemnity under Section
11.2(a) or 11.2(b) above, such party shall promptly notify the other party or
parties, as the case may be, from whom indemnity is or may validly be sought in
writing and the indemnifying party or parties shall assume the defense thereof,
including the employment of counsel.  In addition, in case a party hereto shall
become aware of any facts which might reasonably be expected to result in any
such claim, demand or action, such party shall promptly notify the other party
or parties who would be obligated to provide indemnity hereunder with respect
to such claim, demand or action, and such other party or parties shall have the
right to take such action as it or they may deem appropriate to resolve such
matter.  The indemnified party or parties shall have the right to employ
separate counsel in any such action and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties, unless the employment of such counsel





                                       29
<PAGE>   36
has been specifically authorized by the indemnifying party or parties.  Any
settlement of any action subject to indemnity hereunder shall require the
consent of the indemnified and the indemnifying party which consent shall not
be unreasonably withheld and shall be given within five (5) days following the
giving of notice thereof.  The indemnifying party or parties shall not be
liable for any settlement of any action effected without its or their consent,
but if settled with the consent of the indemnifying party or parties or if
there be a final judgment for the plaintiff in any such action, the
indemnifying party or parties shall indemnify and hold harmless the indemnified
party from and against any loss or liability by reason of such settlement or
judgment.  If requested by the indemnifying party, the indemnified party shall
cooperate with the indemnifying party and its counsel and use its best efforts
in contesting any such claim or, if appropriate, in making any counter-claim or
cross-complaint against the party asserting the claim, provided that the
indemnifying party will reimburse the indemnified party for reasonable
out-of-pocket expenses incurred in so cooperating upon presentation of receipts
or other evidence of such expense.  The indemnifying party and its
representatives shall have full and complete access during reasonable hours to
all books, records and files of the indemnified party expressly related to the
defense of any claim for indemnification undertaken by the indemnifying party
pursuant to this Article 11, or for any other purpose in connection therewith;
provided that the indemnifying party shall safeguard and maintain the
confidentiality of all such books, records and files.

       11.4      Limitations on Indemnification.

                 (a)      General Threshold.  Neither the Sellers nor the
Purchaser shall be obligated to indemnify the other party except to the extent
that the cumulative amount of all indemnifiable losses exceeds Seventy-Five
Thousand Dollars ($75,000.00) (the "Threshold"), which excess amount shall be
recoverable in accordance with the terms hereof; provided, however, that the
$75,000 limitation set forth in this Section 10.4(a) shall not apply to the
matters described in Section 11.4(c).  With respect to any indemnifiable loss
payable by the Sellers, the funds in the Post- Closing Escrow Account shall be
used for such purpose first before any recovery is sought directly from a
Sellers; provided, however, that to the extent the indemnification loss or
losses exceed the funds in the Post-Closing Escrow Account, then the Purchaser
may seek recovery of the amount of such indemnifiable loss in excess of such
funds contemporaneously with the recovery of any funds in the Post-Closing
Escrow Account.

                 (b)      Time Limits for Claims.  No claim for indemnification
may be made by any indemnified party in respect of indemnifiable losses unless
written notice thereof shall have been received by the indemnifying party on or
prior to two years after the date hereof; provided, however, that the two-year
limitation set forth in Section 10.1 and this Section 11.4(b) shall not apply
to the matters described in Section 10.4(c) not reasonably discoverable by
Sellers within the two-year indemnification period set forth in Section 11.1 as
to which the indemnification obligations hereunder shall expire six (6) months
after the termination of the applicable statute of limitations relating to the
subject matter covered by such provisions; and provided further, however, that
in each case if, prior to the applicable date of expiration, a specific state
of facts shall have become known which is reasonably likely to constitute or
give rise to any indemnifiable loss as to which indemnity may be payable and
the indemnified party





                                       30
<PAGE>   37
shall have given notice of such facts to the indemnifying party and made a
claim for indemnification within such two- year period, then the right to
indemnification with respect thereto shall remain in effect until such matter
shall have been finally determined and disposed of and any indemnification due
in respect thereof shall have been paid.

                 (c)      Certain Matters.   The following are the matters 
referred to in Section 11.4(a) and Section 11.4(b):  Losses arising from fraud
or an intentional misrepresentation on the part of any Sellers or an
intentional breach of any covenant or agreement by a Sellers contained in this
Agreement.

       11.5      Remedies; Default; Notice and Cure.  In the event of a breach
of this Agreement prior to the Closing, the non-breaching party shall have all
rights and remedies available at law, in equity or under the terms of the
Agreement.  If the Closing occurs, indemnification pursuant to this Article 11
is the sole and exclusive remedy of the parties after the Closing for matters
arising out of the representations, warranties, covenants and agreements of the
Sellers and the Purchaser set forth in this Agreement (without limiting the
rights of the parties under any other agreement), except as otherwise expressly
provided in this Agreement.  No party shall be deemed in breach of its
obligations hereunder unless it has received written notice from the other
party of noncompliance with a term or provision of this Agreement and has
failed to cure such noncompliance within ten (10) days after receipt of such
notice.

       11.6      Severance Benefits.  The Purchaser shall not be obligated to,
or obligated to cause the Company to, extend any severance benefits to
employees of the Company who may be terminated after the Closing or who are
rendering services to the Company and are terminated prior to the Closing.  In
the event that the Purchaser shall elect to pay or cause the Company to pay any
severance benefits to employees of the Company who may be terminated at or
after the Closing, it is expressly understood that the Sellers shall not be
entitled to receive such severance benefits.

       11.7      Change of Control Application.  Purchaser hereby agrees to
file the applications for governmental approval of a change of control
described in Schedule 4.21 with the appropriate governmental  or regulatory
agencies within five (5) business days of the Effective Date.


                                   ARTICLE 12

and the Sellers;

                 (b)      By Purchaser or Sellers: Condition Precedent.  By
Purchaser or Sellers, upon written notice to the other, if the conditions to
the obligations of such canceling party or





                                       31
<PAGE>   38
parties to consummate the transaction, in the case of the Sellers, as provided
in Article 8 or, in the case of Purchaser, as provided in Article 16, were not,
or cannot reasonably be, satisfied on or before one hundred twenty (120) days
after the date of this Agreement unless the failure of the condition is the
result of the material breach of this Agreement by the party seeking to
terminate; provided, however, that, in the event all such conditions have been
satisfied except solely the condition with respect to obtaining all required
consents, authorizations, and approvals of governmental and regulatory agencies
set forth in Sections 8.1(a) and 9.1(a), respectively, and such failure is not
due to a breach of this Agreement by the non-terminating party, such date shall
be automatically extended for four (4) successive thirty (30) day periods so
long as such remains to be the case at the end of each respective thirty (30)
day period provided, however, that in no event shall such date be extended
beyond an aggregate of two hundred forty (240) days after the date of this
Agreement unless extended by the mutual agreement of the Purchaser and the
Sellers;

                 (c)      By Purchaser or Sellers: Representations, Warranties
and Covenants.  By Purchaser, on the one hand, or Sellers, on the other, if (i)
any representation or warranty of the other hereunder shall not have been true
and correct in all material respects at the time at which made, or (ii) default
shall be made by the other in the due and timely observance or performance of
any of its covenants and agreements herein contained, but in such event only if
such representation or warranty cannot be made true and correct or such default
cannot be cured on or prior to the earlier of (x) sixty (60) days after the
non-defaulting or non-breaching party notifies the other in writing of such
default or breach, specifying the nature thereof or (y) two hundred forty (240)
days after the date of this Agreement, unless such date is extended by mutual
agreement of Purchaser and Sellers.

No termination of this Agreement shall affect the liability of any party hereto
for any breach hereof arising at, prior to or out of such termination;
provided, however, that, in the event of a breach hereof by Purchaser, in
addition to any other remedies available at law or in equity to the Sellers,
Sellers shall be entitled to retain the Earnest Money.  Any public announcement
of the termination of this Agreement shall be made only by means of a press
release issued jointly by Purchaser and the Company.

       12.2      Waiver.  At any time at or prior to the Closing, Purchaser, on
the one hand, or Sellers, on the other, may (i) extend the time for the
performance of any of the obligations or other acts of the other party hereto,
(ii) waive any inaccuracies in the representations and warranties contained
herein or in any document delivered pursuant hereto, or (iii) waive compliance
with any of the agreements or conditions contained herein.  Any agreement on
the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

                                   ARTICLE 14
                                  ARBITRATION

       14.1      Arbitration Procedure.  Subject to the provisions of Section
14.7 below, in the event any matters in Dispute arising out of or relating to
this Agreement (including, but not limited to, actions for injunctive or
declaratory relief) (hereinafter collectively "arbitrable issues") cannot be
settled by agreement between the parties such controversy or dispute shall be
submitted for arbitration in Philadelphia, Pennsylvania, and for this purpose
each party hereby expressly consents to such arbitration in such forum.  The
arbitration process shall proceed as follows:

                 (a)      Step One.  In the event of a Dispute, the disputing
party (herein so called) may at any time notify the other party or parties
("answering party") in writing that the disputing party demands to pursue
arbitration as provided in Step Two below, setting forth in specific terms the
disputing party's proposed statement of the matters in Dispute to be submitted
to arbitration and the name and address of the arbitrator selected by the
disputing party.  Within five (5) business days following receipt of the
disputing party's written arbitration demand complying with the requirements of
this Step One, each answering party shall notify the disputing party in
writing, setting forth in specific terms the answering party's proposed
statement of the matter in Dispute and identifying the name and address of the
arbitrator selected by such answering party.  For purposes of this Section
14.1, all persons constituting the Sellers shall act as one party in selecting
an arbitrator, whether as a disputing party or as an answering party.

                 (b)      Step Two.  The two (2) or more arbitrators so
selected shall meet and confer within twenty (20) business days after receipt
by the disputing party of all of the answering parties' written notices as
called for under Step One above, and if they are unable within said twenty (20)
day period to reach a decision on the matters in Dispute, they shall, at the
expiration of said twenty (20) day period, jointly select a neutral arbitrator.
If said arbitrators are unable to choose a neutral arbitrator, any party may
request the AAA to appoint an additional arbitrator from its National Panel of
Commercial Arbitrators.  Any party to this Agreement may advise the AAA that
time is of the essence and that the parties to this Agreement would like such
selection as soon as is reasonably possible, it being expressly understood in
such AAA selection process that the selection is in the sole discretion of the
AAA, and that the AAA shall not be required by reason of this Agreement to
consult with the parties to this Agreement in said selection process; provided
that all arbitrators, including the additional arbitrator selected by the AAA,
shall be disinterested individuals knowledgeable in commercial transactions.
Upon selection of the additional arbitrator, all arbitrators shall within ten
(10) business days thereafter convene an arbitration proceeding at a date, time
and place (in metropolitan Philadelphia, Pennsylvania) designated by said
arbitrators by a majority vote, written notice of which shall be given to the
parties not later than seven (7) calendar days prior to said hearing date.  At
the hearing, each party may be represented by counsel and present testimony and
evidence.  If at the commencement of the hearing the parties cannot agree on a
joint statement of the matters in Dispute to be submitted to the arbitrators,
the arbitrators shall be empowered to frame the submission issue(s).  A
Certified Court Reporter's transcript may





                                       35
<PAGE>   42
be demanded by any party or by the arbitrators and said official transcript
shall be prepared, completed, and delivered to the arbitrators with copies to
each party within ten (10) business days following the conclusion of the
hearing.  Arbitration sessions following the initial session, if necessary,
shall be scheduled by the arbitrators so that the arbitration proceedings
(i.e., presentation of evidence and/or oral arguments) are completed within
twenty (20) days of the initial session.  Each party shall be given the
opportunity to file with the arbitrators simultaneous written briefs five (5)
business days following receipt by the arbitrators of the official transcript
but, if no transcript is demanded as provided in this Agreement, said briefs
shall be filed simultaneously five (5) business days following conclusion of
the hearing.  Copies of any such briefs shall be provided to the other party
concurrently upon filing with the arbitrators.

                 (c)      Step Three.  Within ten (10) business days following
the receipt by the arbitrators of the brief(s) (or within ten (10) business
days following conclusion of the hearing if all parties waive briefs), the
arbitrators shall make and deliver to the parties their decision and award in
writing.  The arbitrators shall have the authority to enter any award or to
grant any relief which could be obtained in a court of competent jurisdiction
and reasonable attorneys', arbitrators' and experts' fees and expenses of
arbitration may be awarded as the arbitrators see fit, consistent with the
provisions of this Agreement.  The arbitrators shall have no authority to
modify, amend or alter the provisions of this Agreement and shall base their
decision and award on applicable law, the language contained in this Agreement
and the facts giving rise to the Dispute as presented on the record at the
hearing.  The arbitrators shall issue a written opinion explaining the basis
for their findings.

       14.2      Self-Execution.  It is expressly understood between the
parties that this Article 14 is a self- executing arbitration provision and
that any party may unilaterally select an arbitrator if the other party refuses
to arbitrate.  It is further expressly agreed that said unilaterally-selected
arbitrator may proceed to arbitrate the issue(s) and the arbitration and
decision shall be self-executing and therefore shall not require the order of
any Court to proceed.  The parties may, however, mutually stipulate in writing
to extend or to shorten the prescribed time periods (including a stipulation to
expedite the referral and submission to arbitration).  All provisions of this
Agreement not in dispute shall be observed and performed without interruption
during the pendency of any proceeding called for under this Article 14.

       14.3      Arbitrator's Fees.  If an additional arbitrator is required
pursuant to Step Two under Section 14.1, each party shall pay its pr rata share
of any required retainer or other payments required by such arbitrator upon
such arbitrator's demand, with the ultimate responsibility for the arbitrators'
fees to be determined by the arbitrators in the final arbitration award
pursuant to Step Three of Section 14; otherwise, each party shall bear its own
costs and expenses in connection with any proceedings under this Article 14
and, in any event, each party shall pay the fees of the arbitrator it selects.

       14.4      Rules Governing Arbitration.  In all other respects, the
arbitration shall be conducted pursuant to the then-existing Commercial Rules
of the AAA to the extent such rules are not inconsistent with any provision of
this Agreement.  Subject to the foregoing, the arbitrators shall determine the
scope and extent of permissible discovery, if any.





                                       36
<PAGE>   43
       14.5      Entry of Award.  The award of the arbitrators may be entered
as a final judgment by any court of competent jurisdiction.

       14.6      Injunctive Relief.  Notwithstanding the provisions of this
Article 14 to the contrary, each party shall be entitled to seek temporary or
preliminary injunctive relief from a court of competent jurisdiction if the
failure to immediately obtain injunctive relief will result in irreparable harm
to that party.  The jurisdiction of the court shall extend only to such relief
and any request for permanent injunctive relief shall remain subject to the
arbitration provisions of this Agreement.

       14.7      Non-Applicability to Note.  Notwithstanding any provision of
this Article 14 to the contrary, the provisions of this Article 14 shall
expressly not apply to any dispute arising out or relating to the Note.


                                   ARTICLE 15
                                 MISCELLANEOUS

       15.1      Further Instruments.  The parties hereto agree to execute and
deliver such instruments and take such other action as shall be reasonably
necessary, or as shall be reasonably requested by any other party, in order to
carry out the transactions, agreements and covenants contemplated in this
Agreement at or prior to the Closing Date.

       15.2      Notices.  Any notices, claims or demands which any party is
required or may desire to give to another under or in conjunction with this
Agreement shall be in writing, and shall be given by addressing the same to
such other party(ies) at the address set forth below, and by (i) depositing the
same so addressed, postage prepaid, first class, certified or registered, in
the United States mail (herein referred to as "Mailing"), (ii) overnight
delivery by a nationally recognized overnight courier service (e.g. UPS,
Federal Express), (iii) delivering the same personally to such other

days following the date of Mailing; one day after timely delivery to an
overnight courier; if by personal delivery, upon such delivery; or if by
facsimile, the day of transmission if made within customary business hours, or

       15.3      Entire Agreement; Amendments.  This Agreement and the
documents to be delivered at Closing hereunder set forth the entire
understanding of the parties and supersede all prior agreements or
understandings, whether written or oral, with respect to the subject matter
hereof.  This Agreement may be amended, modified or supplemented only by a
written agreement executed by Purchaser and Sellers.

       15.4      Binding Effect/Assignability.  This Agreement shall extend to
and be binding upon and inure to the benefit of the parties hereto, their
respective heirs, legal representatives, successors and assigns.  Purchaser
shall have the right at any time to assign this Agreement to any affiliate of
Purchaser without the necessity of seeking the consent of the Sellers;
provided, however, that Purchaser shall not be relieved of any obligations as a
result of such assignment and that, in addition to Purchaser remaining liable,
any such assignee shall assume and become liable for any and all of Purchaser's
obligations under this Agreement.  None of the Sellers shall be entitled to
assign any of their respective rights or obligations under this Agreement;
provided, however, that the rights and obligations of a Sellers may be assigned
by operation of law or may be assigned to an individual retirement account,
pension plan, trust or other entity under the control of such Sellers but any
such assignment shall not relieve or release such Sellers of any





                                       38
<PAGE>   45
obligations hereunder as a result of such assignment and that, in addition to
such Sellers remaining liable, any such assignee shall assume and become liable
for any and all of such Sellers' obligations under this Agreement. In
connection with any such assignment, Sellers may transfer all or any portion of
the Shares owned by the Sellers and thereby effect an assignment on the basis
specified above.

       15.5      Exhibits/Schedules.  All Exhibits and Schedules referenced in
this Agreement are incorporated herein by reference and shall constitute a part
of this Agreement.

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

       15.7      Headings/Captions.  The captions to sections and subsections
of this Agreement have been inserted solely for convenience and reference, and
shall not control or affect the meaning or construction of any of the
provisions of this Agreement.

       15.8      Waiver; Remedies.  Waiver by any party hereto of any breach of
or exercise of any rights under this Agreement shall not be deemed to be a
waiver of similar or other breaches or rights or a future breach of the same
duty.  The failure of a party to take any action by reason of any such breach
or to exercise any such right shall not deprive any party of the right to take
any action at any time while such breach or condition giving rise to such right
continues.  Except as expressly limited by this Agreement, the parties shall
have all remedies permitted to them by this Agreement or law, and all such
remedies shall be cumulative.

       15.9      Attorney's Fees and Costs.  In the event of a breach by any
party to this Agreement and commencement of a subsequent legal action in a
court of law or forum of arbitration, or in the event legal counsel is
consulted in the event of any such breach or in anticipation of any such
prospective legal action, the prevailing party in any such dispute shall be
entitled to reimbursement of reasonable attorney's fees and court costs,
including, but not limited to, the costs of expert witnesses, transportation,
lodging and meal costs of the parties and witnesses, costs of transcript
preparation and other reasonable and necessary direct and incidental costs of
such dispute.  A party shall be deemed to be a "prevailing party" under this
Section only if:

                 (a)      the judgment or award against it is equal to or less
than eighty percent (80%) of that party's written settlement offer; or,





                                       39
<PAGE>   46
                 (b)      the judgment or award in its favor is equal to or
greater than one hundred and twenty percent (120%) of that party's written
settlement demand.

                 The party responsible for attorneys' fees and costs under this
provision shall only be responsible for those attorney's fees and costs
incurred from a point in time commencing twenty (20) days after receipt of the
offer or demand of settlement under (a) or (b) above.

                 Adjudication of a party's entitlement to counsel fees shall be
by way of a non-jury proceeding following adjudication of the underlying claim.

       15.10     Time.  Time is of the essence under this Agreement.

       15.11     Governing Law.  This Agreement shall be construed under and
governed by the internal laws, and not the law of conflicts, of the State of
New Jersey.

       15.12     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same agreement.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement is entered into on May 13, 1996 by and
between United Dental Care, Inc., a Delaware corporation, (hereinafter referred
to as "UDC"), and William H. Wilcox (hereinafter referred to as "Employee"),
with reference to the following facts:

                                    RECITALS

         UDC desires to employ employee in the capacity and on the terms and
conditions hereinafter set forth and employee is willing to serve is such
capacity and on such terms and conditions.

         NOW, THEREFORE, it is hereby agreed to as follows:

         1.      EMPLOYMENT. UDC hereby employs Employee as President and Chief
Executive officer of UDC. References herein to UDC shall be deemed to include
references to any and all subsidiaries.

         2.      DUTIES. During his employment, Employee shall devote
substantially all of his working time, energies and skills to the benefit of
UDC's business. Employee agrees to serve UDC diligently and to the best of his
ability. In his capacity as CEO, Employee shall report to the Board of
Directors of UDC and shall have such duties, responsibilities, and authority as
are set forth in the Bylaws of UDC and as typically identified with such
position. In his capacity as CEO, Employee shall have authority to hire such
staff as Employee determines is necessary and to determine the titles and
compensation levels of such staff, subject to approval of the Compensation
Committee for salaries over $100,000 and subject to the election by the Board
of Directors of Officers.

         3.      COMPENSATION. Employee's compensation under this Agreement
shall be as follows:

                 (a)      BASE SALARY. UDC shall pay Employee a base salary
("Base Salary") of $300,000 per year. In addition, the Board of Directors of
UDC shall, in good faith, consider granting increases in such salary based upon
such factors as Employee's performance and the growth and/or profitability of
UDC, but it shall have no obligation to grant any such increases in
compensation. Such Base Salary shall be payable at such times and in such
installments as other UDC executives are paid. All payments shall be subject to
the deduction of payroll taxes and similar assessments as required by law.

                 (b)      BONUS. In addition to the Base Salary, Employee shall
be eligible to receive bonus compensation in such amounts and at such times as
the Compensation Committee of UDC shall, from time to time, determine.

         4.      EXPENSES AND BENEFITS. Employee is authorized to incur
reasonable expenses in connection with the business of UDC including expenses
for entertainment, travel and similar matters. UDC will reimburse Employee for
such expenses upon presentation by Employee of such accounts and records as UDC
shall from time to time require. UDC also agrees to provide Employee with the
following benefits:

                 (a)      INSURANCE. Major medical health insurance and
disability insurance as currently in place.




PAGE 1
<PAGE>   2
                 (b)      EMPLOYEE BENEFIT PLANS. Participation in any other
employee benefit plans now existing or hereafter adopted by UDC for its
employees.

                 (c)      OTHER. Such items and benefits as UDC shall, from
time to time, consider necessary or appropriate to assist Employee in the
performance of his duties.

                 (d)      VACATIONS. Employee shall be entitled (in addition to
the usual public holidays) to a paid vacation for a period in each calendar
year of four weeks, to be taken at such times as may be approved by UDC.

         5.      TERM. The term of this Agreement shall be from the date of
this Agreement to May 31, 1999, and shall thereafter be automatically renewed
for successive two year terms; provided, however, that either party may
terminate this Agreement at any time upon at least 60 days prior written
notice. A determination by UDC to terminate this Agreement may be made only by
an affirmative vote of not less than seventy-five percent (75%) of the members
of the Board of Directors of UDC then in office. In the event of such
termination by UDC, Employee shall be entitled to severance pay based on his
Base Salary at the time of termination, plus a bonus (payable monthly on a pro
rata basis) at a rate equal to the average annual bonuses paid to Employee for
the two calendar years preceding the date of notice of termination for a period
of 24 months following termination or until May 31, 1999, whichever is later.
Such severance pay shall be payable in monthly installments and UDC shall
continue the benefits set forth is Sections 4(a) and (b) for the period during
which such severance payments are to be made. In addition, this Agreement shall
terminate as provided for in Section 7 or upon the death of Employee.

         6.      DISABILITY

                 (a)      In the event that Employee becomes Permanently
Disabled (as hereinafter defined) during the term of this Agreement, Employee
shall continue in the employ of UDC but his compensation hereunder shall be
reduced to three-fourths of the Base Salary then in effect as set forth in
Section 3(a) hereof, commencing upon the determination of Employee's Permanent
Disability and continuing thereafter until the first to occur of (i) 36 months
or (ii) the death of Employee; and during such period of time, Employee shall
not be entitled to payment of expenses or benefits specified in Section 4
hereof (except for reimbursement of expenses incurred by Employee prior to
becoming Permanently Disabled), except that UDC shall continue to provide
Employee with the insurance benefits specified in Section 4(a) hereof. The
obligation of UDC for continuation of three-fourths of Employee's Base Salary
shall be net of payments to Employee from the disability insurance referred to
in Section 4(a) hereof.

                 (b)      DEFINITION OF DISABILITY. For purposes of the
Agreement, the terms "Permanent Disability" or "Permanently Disabled" shall mean
three months of substantially continuous disability. Disability shall be deemed
"substantially continuous" if, as a practical matter, Employee, by reason of his
mental or physical health, is unable to sustain reasonably long periods of
substantial performance of his duties. Frequent long illnesses, though different
from the preceding illness and though separated by relatively short periods of
performance, shall be deemed to be "substantially continuous." Disability shall
be determined in good faith by the Board of Directors, whose decision shall be
final and binding upon Employee. Employee hereby consents to medical
examinations by such physicians and medical consultant as UDC shall, from time
to time, require.

         7.      TERMINATION BY UDC. UDC shall have the right to terminate
Employee's employment as hereinafter provided.

                 (a)      TERMINATION BY UDC FOR CAUSE. UDC shall have the
right to terminate Employee's employment under this Agreement for Cause by an
affirmative vote to so terminate by not less than seventy-five percent (75%) of
the members of UDC's Board of Directors, in which event, no compensation shall
be paid or other benefits furnished to Employee after termination for Cause.
Termination for Cause shall be effective immediately upon notice sent or given
to Employee.

                 (b)      DEFINITION OF CAUSE. For purposes of this Agreement,
the term "Cause" shall mean and be strictly limited to: (i) conviction of a
crime constituting a felony under state or federal law; (ii) commission of any
material act of dishonesty against UDC; or (iii) willful and material breach of
this Agreement by Employee.

         8.      CHANGE OF CONTROL. For purposes of Section 9 of this
Agreement, "Change of Control" shall mean: (i) a change of stock ownership of
UDC of a nature that would be required to be reported in response to Item 6(e)
of Schedule 14A promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") and any successor Item of a similar nature; or
(ii) the acquisition of beneficial ownership, directly or indirectly, by any
person (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange
Act) of securities of UDC representing 25% or more of the combined voting power
of UDC's then outstanding securities; or (iii) a change during any period of
two consecutive years of a majority of the members of the Board of Directors of
UDC for any reason, unless the election, or the nomination for election by
UDC's shareholders, of each director was approved by a vote of at least
two-thirds of the directors then still in office who were directors at the
beginning of the period. Notwithstanding the foregoing, no Change of Control
shall be deemed to have occurred in connection with any merger or similar
transaction to which UDC is a party if at least one-half of the members of the
Board of Directors of the ultimate parent corporation of the surviving
corporate group consist of persons who were member of UDC's Board or on the
date hereof or persons elected or nominated for election by such persons.

                 (a)      GOOD REASON. In the event of a Change of Control,
Employee's Employment may be terminated by the Employee for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean:

                          (i)     the assignment to the Employee of any duties
inconsistent in any material respect with the Employee's position (including
status, offices, titles and reporting requirements), authority, duties or
responsibilities as contemplated by Sections 1 and 2 of this Agreement or
moving to an office more than 15 miles away, or any other action that results
in material diminution in such position, authority, duties or responsibilities;

                          (ii)    any failure by UDC to comply with any of the
provisions of Section 3 of this Agreement, other than an isolated insubstantial
and inadvertent failure not occurring in bad faith and which is remedied by UDC
promptly after receipt of notice thereof given by the Employee.

                 (b)      UDC will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of UDC to assume expressly and
agree to perform this Agreement in the same manner and to the same extent that
UDC would be required to perform if no such succession had taken place.

<PAGE>   4
         9.      STOCK OPTIONS. In the event that UDC elects to terminate this
Agreement pursuant to Section 5 or in the event of a Change of Control of UDC
the Employee's employment is terminated by the Employee for Good Reason (or in
the event UDC breaches this Agreement by termination of Employee without the
notice required under Section 5 or without Cause under Section 7), then UDC
shall amend all UDC stock options held by him and all restricted stock awards
made to him (whether issued subject to forfeiture or to be issued when and if
they become vested) so as to (a) cause to vest,  immediately prior to the date
of such Change in Control or termination of employment, all such then unvested
stock options and restricted stock awards, and (b) provide Employee 90 days to
exercise such options (or such greater period as may have been provided in the
terms of such options). In addition, UDC will, consistent with all applicable
laws and regulations, use its reasonable efforts to assist Employee in securing
independent third party financing of the funds required by employee to exercise
all vested but unexercised stock options held by him. If such financing is not
so obtained by Employee, then UDC shall loan to Employee the funds required by
Employee to exercise such options, which loan shall be repayable one year from
the date made, will be secured by UDC's common stock purchased upon exercise of
such options and will bear interest at the prime rate (floating) of Bank One -
Texas, N.A. To the extent that UDC refuses or is unable to comply with the
provisions of Section 9(a) hereof, the time period contemplated in Section 9(b)
shall commence on the date UDC complies with the provision of said Section
9(a).

         10.     CERTAIN REDUCTION OF PAYMENTS BY UDC,

                 (a)      Notwithstanding anything to the contrary in Sections
8 and 9 of this Agreement, in no event shall a Stock Option become immediately
exercisable or the restrictions relating to Restricted Stock terminate upon the
Employee's Termination if such acceleration would (i) cause any payment made to
the Employee, whether pursuant to the terms of this Agreement or otherwise (a
"Payment") to constitute an "excess parachute payment" within the meaning of
Section 28OG of the Internal Revenue Code of 1986, as amended (the "Code"), or
(ii) disqualify the transaction constituting the Change of Control from being
accounted for as a "pooling of interests" within the meaning of APB No. 16,
which, would qualify for such accounting treatment in the absence of such
acceleration (the "Disqualification"). In the event acceleration of any Option
Rights would cause any Payment to constitute an excess parachute payment, or
would cause a Disqualification, the Compensation Committee of the UDC Board of
Directors shall select the Stock Options which shall remain unexercisable so
that no Payment shall constitute an excess parachute payment and/or no
Disqualification shall occur. Any Stock Options which remain unexercisable upon
the Employee's Termination by reason of this Section 11 (a) shall become
exercisable as set forth in Section 11 (b) below.

                 (b)      In the event that any Stock Option which is
outstanding on the Employee's Termination has not become exercisable because of
the application of this Section 11, such Stock Option will become exercisable
in such manner and at such times as the Stock Option would have become
exercisable if the Employee had not terminated employment, and the portion of
any such Stock Option which becomes exercisable pursuant to this Section 11(b)
shall remain exercisable until the earlier of the date which is 90 days
following the date on which the Stock Option first becomes exercisable or the
original expiration date of the Stock Option.

         11.     NON-COMPETITION AND CONFIDENTIALITY.

                 (a)      NON-COMPETITION. Employee recognizes and understands
that in performing the responsibilities of his employment, he will occupy a
position of fiduciary trust and confidence, pursuant to which he will develop
and acquire experience and knowledge with respect to UDC's business. It is the
expressed intent and agreement of Employee and UDC that such knowledge and
experience shall be used exclusively in the furtherance of the interests of UDC
and not in any manner which would be detrimental to UDC's interests. Employee
further understands and agrees that UDC conducts its business within a
specialized market segment throughout the United States, and that it would be
detrimental to the interests of UDC if Employee used the knowledge and
experience which he currently possesses or which he acquires pursuant to his
employment hereunder for the purpose of directly or indirectly competing with
UDC, or for the purpose of aiding other persons or entities in so competing
with UDC, anywhere in the United States. Employee therefore agrees that so long
as he is employed by UDC and for a period of the greater of (i) one year from
the date of notification by Employee of termination or (ii) the time Employee
is receiving a salary or severance payments or (iii) the time granted under
Section 9 to Employee to exercise stock options if options are exercised or
(iv) such time as UDC is loaning money or has a loan outstanding to Employee,
unless Employee first secures the written consent of UDC, Employee will not
directly or indirectly invest, engage or participate in or become employed by
any entity in direct or indirect competition with UDC's business (which shall
include the ownership and/or operation of managed dental plans) anywhere in the
United States, or contract to do so. These non-competition provisions are not
to be construed to prohibit Employee from being employed in the health care
industry, but rather to permit him to be so employed so long as such employment
does not involve Employee's direct or indirect participation in a business
which is the same or similar to UDC's business (as defined above). In the event
that the provisions of this Section 10 should ever be deemed to exceed the time
or geographic limitations permitted by applicable laws, then such provisions
shall be-reformed to the maximum time or geographic limitations permitted by
applicable laws.

                 (b)      REMEDIES. Employee acknowledges that the restrictions
contained in Section 10(a), in view of the nature of the business in which UDC
is engaged, are reasonable and necessary to protect the legitimate interests of
UDC. Employee understands that the remedies at law for his violations of any of
the covenants or provisions of Section 10(a) will be inadequate, that such
violation will cause irreparable injury within a short period of time, and that
UDC shall be entitled to preliminary injunctive relief against such violation.
Such injunctive relief shall be in addition to, and in no way in limitation of,
any and all other remedies UDC shall have in law and equity for the enforcement
of those covenants and provisions.

         12.     GENERAL PROVISIONS.

                 (a)      NOTICES. Any notice to be given hereunder by either
party to the other may be effected by personal delivery, in writing or by mail,
registered or certified, postage prepaid with return receipt requested. Mailed
notices shall be addressed to the parties at the addresses set forth below, but
each party may change his or its address by written notice in accordance with
this Section 11 (a). Notice deleted personally shall be deemed communicated as
of the actual receipt; mailed notices shall be deemed communicated as of three
days after mailing.

unenforceable, the remaining provisions shall, nevertheless, continue in
full force and without being impaired or invalidated in any way.

                 (c)      GOVERNING AGREEMENT. This Agreement shall be governed
by and construed in accordance with the laws of the State of Texas.

equity is necessary to enforce or interpret the terms of this Agreement, the
prevailing party shall be entitled to reasonable attorneys' fees, costs and
necessary disbursements in addition to any other relief to which he or it may
be entitled.

all other Agreements, either oral or in writing, between the parties hereto
with respect to employment of Employee by UDC and contains all of the covenants
and agreements between the parties with respect to such employment. Each party
to this Agreement acknowledges that no representations, inducements or
agreements, oral or otherwise, have been embodied herein, and no other
agreement, statement or promise not contained in this Agreement shall be valid
or binding. Any modification of this Agreement will be effective only if it is
in writing signed by the party to be charged.

                          IN WITNESS WHEREOF, the parties have executed this
Agreement as of the date first written above.

                 (b)      BONUS. In addition to the Base Salary, Employee shall

employee benefit plans now existing or hereafter adopted by UDC for its
employees.

                 (c)      OTHER. Such items and benefits as UDC shall, from
time to time, consider necessary or appropriate to assist Employee in the
performance of his duties.

                 (d)      VACATIONS. Employee shall be entitled (in addition to
the usual public holidays) to a paid vacation for a period in each calendar
year of four weeks, to be taken at such times as may be approved by UDC.

         5.      TERM. The term of this Agreement shall be from the date of
this Agreement to May 31, 1998; provided, however, that either party may
terminate this Agreement at any time upon at least 60 days prior written
notice. In the event of such termination by UDC, Employee shall be entitled to
severance pay based on his Base Salary at the time of termination, plus a bonus
(payable monthly on a pro rata basis) at a rate equal to the average annual
bonuses paid to Employee for the two calendar years preceding the date of
notice of termination for a period of 12 months following termination or until
May 31, 1998, whichever is later. Such severance pay shall be payable in
monthly installments and UDC shall continue the benefits set forth is Sections

         6.      DISABILITY.

                 (a)  In the event that Employee becomes Permanently Disabled

continue in the employ of UDC but his compensation hereunder shall be reduced
to three-fourths of the Base Salary then in effect as set forth in Section 3(a)
hereof, commencing upon the determination of Employee's Permanent Disability

death of Employee; and during such period of time, Employee shall not be
entitled to payment of expenses or benefits specified in Section 4 hereof
(except for reimbursement of expenses incurred by Employee prior to becoming
Permanently Disabled), except that UDC shall continue to provide Employee with
the insurance benefits specified in Section 4(a) hereof. The obligation of UDC
for continuation of three-fourths of Employee's Base Salary shall be net of
payments to Employee from the disability insurance referred to in Section 4(a)
hereof.

                 (b)      DEFINITION OF DISABILITY. For purposes of the
Agreement, the terms "Permanent Disability" or "Permanently Disabled" shall
mean three months of substantially continuous disability. Disability shall be
deemed "substantially continuous" if, as a practical matter, Employee, by
reason of his mental or physical health, is unable to sustain reasonably long
periods of substantial performance of his duties. Frequent long illnesses,
though different from the preceding illness and though separated by relatively
short periods of performance, shall be deemed to be "substantially continuous."
Disability shall be determined in good faith by the Board of Directors, whose
decision shall be final and binding upon Employee. Employee hereby consents to
medical examinations by such physicians and medical consultant as UDC shall,
from time to time, require.

         7.      TERMINATION BY UDC. UDC shall have the right to terminate

PAGE 2
<PAGE>   3
                 (a)      TERMINATION BY UDC FOR CAUSE. UDC shall have the
right to terminate Employee's employment under this Agreement for Cause by an
affirmative vote to so terminate by a majority of all of the members of UDC's
Board of Directors, in which event, no compensation shall be paid or other
benefits furnished to Employee after termination for Cause. Termination for
Cause shall be effective immediately upon notice sent or given to Employee.

                 (b)      DEFINITION OF CAUSE. For purposes of this Agreement,
the term "Cause" shall mean and be strictly limited to: (i) conviction of a
crime constituting a felony under state or federal law; (ii) commission of any
material act of dishonesty against UDC; or (iii) willful and material breach of
this Agreement by Employee.

         8.      CHANGE OF CONTROL. For purposes of Section 9 of this
Agreement, "Change of Control" shall mean: (1) a change of stock ownership of
UDC of a nature that would be required to be reported in response to Item 6(e)
of Schedule 14A promulgated under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") and any successor Item of a similar nature; or
(ii) the acquisition of beneficial ownership, directly or indirectly, by any
person (as such term is used in Sections 13(d) and 14(d)(2) of the Exchange
Act) of securities of UDC representing 25% or more of the combined voting power
of UDC's then outstanding securities; or (iii) a change during any period of
two consecutive years of a majority of the members of the Board of Directors of
UDC for any reason, unless the election, or the nomination for election by
UDC's shareholders, of each director was approved by a vote of at least
two-thirds of the directors then still in office who were directors at the
beginning of the period. Notwithstanding the foregoing, no Change of Control
shall be deemed to have occurred in connection with any merger or similar
transaction to which UDC is a party if at least one-half of the members of the
Board of Directors of the ultimate parent corporation of the surviving
corporate group consist of persons who were member of UDC's Board or on the
date hereof or persons elected or nominated for election by such persons.

                 (a)      GOOD REASON. In the event of a Change of Control,
Employee's Employment may be terminated by the Employee for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean:

                          (i)     the assignment to the Employee of any duties
which reflect a material diminution of the employee's position, authority,
duties or responsibilities. Whether or not a material diminution of the
employee's position, authority, duties or responsibilities has occurred will be
determined by the Executive Committee of UDC which is in place prior the
"Change of Control." Employee hereby agrees to accept and abide by that
determination.

                 (ii)     any failure by UDC to comply with any of the
provisions of Section 3 of this Agreement, other than an isolated insubstantial
and inadvertent failure not occurring in bad faith and which is remedied by UDC
promptly after receipt of notice thereof given by the Employee.

                 (b)      UDC will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of UDC to assume expressly and
agree to perform this Agreement in the same manner and to the same extent that
UDC would be required to perform if no such succession had taken place and
honor existing option agreements.

         9. STOCK OPTIONS. In the event that UDC elects to terminate this 
Agreement pursuant to Section 5 or in the event of a Change of Control of UDC
the Employee's employment is terminated by the Employee for Good Reason (or in
the event UDC breaches this Agreement by termination of Employee without the
notice required under Section 5 or without Cause under Section 7), then UDC
shall amend at least one half of all UDC stock options held by him and all
restricted stock awards made to him (whether issued subject to forfeiture or to
be issued when and if they become vested) so as to (a) cause to vest,
immediately prior to the date of such Change in Control or termination of
employment, all such then unvested stock options and restricted stock awards,
and (b) provide Employee 90 days to exercise such options (or such greater
period as may have been provided in the terms of such options). The Compensation
Committee of UDC, in place prior to the "Change in Control," will have the
ability to cause more than one-half of these options to vest. Such determination
will be made at the sole discretion of the Compensation Committee. In addition,
UDC will, consistent with all applicable laws and regulations, use its
reasonable efforts to assist Employee in securing independent third party
financing of the funds required by employee to exercise all vested but
unexercised stock options held by him. If such financing is not so obtained by
Employee, then UDC shall loan to Employee the funds required by Employee to
exercise such options, which loan shall be repayable one year from the date
made, will be secured by UDC's common stock purchased upon exercise of such
options and will bear interest at the prime rate (floating) of Bank One - Texas,
N.A. To the extent that UDC refuses or is unable to comply with the provisions
of Section 9(a) hereof, the time period contemplated in Section 9(b) shall
commence on the date UDC complies with the provision of said Section 9(a).

         10.     CERTAIN REDUCTION OF PAYMENTS BY UDC.

                 (a)      Notwithstanding anything to the contrary in Sections
8 and 9 of this Agreement, in no event shall a Stock Option become immediately
exercisable or the restrictions relating to Restricted Stock terminate upon the
Employee's Termination if such acceleration would (i) cause any payment made to
the Employee, whether pursuant to the terms of this Agreement or otherwise (a
"Payment") to constitute an "excess parachute payment" within the meaning of
Section 28OG of the Internal Revenue Code of 1986, as amended (the "Code"), or
(ii) disqualify the transaction constituting the Change of Control from being
accounted for as a "pooling of interests" within the meaning of APB No. 16,
which would qualify for such accounting treatment in the absence of such
acceleration (the "Disqualification"). In the event acceleration of any Option
Rights would cause any Payment to constitute an excess parachute payment, or
would cause a Disqualification, the Compensation Committee of the UDC Board of
Directors shall select the Stock Options which shall remain unexercisable so
that no Payment shall constitute an excess parachute payment and/or no
Disqualification shall occur. Any Stock Options which remain unexercisable upon
the Employee's Termination by reason of this Section 10(a) shall become
exercisable as set forth in Section 10(b) below.

                 (b)      In the event that any Stock Option which is
outstanding on the Employee's Termination has not become exercisable because of
the application of this Section 10, such Stock Option will become exercisable
in such manner and at such times as the Stock Option would have become
exercisable if the Employee had not terminated employment, and the portion of
any such Stock Option which becomes exercisable pursuant to this Section 10(b)
shall remain exercisable until the earlier of the date which is 90 days
following the date on which the Stock Option first becomes exercisable or the
original expiration date of the Stock Option.

         11.     NON-COMPETITION AND CONFIDENTIALITY,

                 (a)      NON-COMPETITION. Employee recognizes and understands
that in performing the responsibilities of his employment, he will occupy a
position of fiduciary trust and confidence, pursuant to which he will develop
and acquire experience and knowledge with respect to UDC's business. It is the
expressed intent and agreement of Employee and UDC that such knowledge and
experience shall be used exclusively in the furtherance of the interests of UDC
and not in any manner which would be detrimental to UDC's interests. Employee
further understands and agrees that UDC conducts its business within a
specialized market segment throughout the United States, and that it would be
detrimental to the interests of UDC if Employee used the knowledge and
experience which he currently possesses or which he acquires pursuant to his
employment hereunder for the purpose of directly or indirectly competing with
UDC, or for the purpose of aiding other persons or entities in so competing
with UDC, anywhere in the United States. Employee therefore agrees that so long
as he is employed by UDC and for a period of the greater of (i) one year from
the date of notification by employee of termination (ii) the time Employee is
receiving a salary or severance payments or (iii) the time granted under
Section 9 to Employee to exercise stock options if options are exercised or
(iv) such time as UDC is loaning money or has a loan outstanding to Employee,
unless Employee first secures the written consent of UDC, Employee will not
directly or indirectly invest, engage or participate in or become employed by
any entity in direct or indirect competition with UDC's business (which shall
include the ownership and/or operation of managed dental plans) anywhere in the
United States, or contract to do so. These non-competition provisions are not
to be construed to prohibit Employee from being employed in the health care
industry, but rather to permit him to be so employed so long as such employment
does not involve Employee's direct or indirect participation in a business
which is the same or similar to UDC's business (as defined above). In the event
that the provisions of this Section 11 should ever be deemed to exceed the time
or geographic limitations permitted by applicable laws, then such provisions
shall be reformed to the maximum time or geographic limitations permitted by
applicable laws.

                 (b)      REMEDIES. Employee acknowledges that the restrictions
contained in Section 10(a), in view of the nature of the business in which UDC
is engaged, are reasonable and necessary to protect the legitimate interests of
UDC. Employee understands that the remedies at law for his violations of any of
the covenants or provisions of Section 10(a) will be inadequate, that such
violation will cause irreparable injury within a short period of time, and that
UDC shall be entitled to preliminary injunctive relief against such violation.
Such injunctive relief shall be in addition to, and in no way in limitation of,
any and all other remedies UDC shall have in law and equity for the enforcement
of those covenants and provisions.

         12.     GENERAL PROVISIONS.

                 (a)      NOTICES. Any notice to be given hereunder by either
party to the other may be effected by personal delivery, in writing or by mail,
registered or certified, postage prepaid with return receipt requested. Mailed
notices shall be addressed to the parties at the addresses set forth below, but
each party may change his or its address by written notice in accordance with
this Section 12(a). Notice deleted personally shall be deemed communicated as
of the actual receipt; mailed notices shall be deemed communicated as of three
days after mailing.

force and without being impaired or invalidated in any way.

necessary disbursements in addition to any other relief to which he or it may

ultimate parent corporation of the surviving corporate group consist of persons
who were member of UDC's Board or on the date hereof or persons elected or
nominated for election by such persons.

                 (a)      GOOD REASON. In the event of a Change of Control,
Employee's Employment may be terminated by the Employee for Good Reason. For
purposes of this Agreement, "Good Reason" shall mean:

                          (i)     the assignment to the Employee of any duties
which reflect a material diminution of the employee's position, authority,
duties or responsibilities. Whether or not a material diminution of the
employee's position, authority, duties or responsibilities has occurred will be
determined by the Executive Committee of UDC which is in place prior to the
"Change of Control." Employee hereby agrees to accept and abide by that
determination.

                          (ii)    any failure by UDC to comply with any of the
provisions of Section 3 of this Agreement, other than an isolated insubstantial
and inadvertent failure not occurring in bad faith and which is remedied by UDC
promptly after receipt of notice thereof given by the Employee.

                 (b)      UDC will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of UDC to assume expressly and
agree to perform this Agreement in the same manner and to the same extent that
UDC would be required to perform if no such succession had taken place and
honor existing option agreements.

         9.      STOCK OPTIONS. In the event that UDC elects to terminate this
Agreement pursuant to Section 5 or in the event of a Change of Control of UDC
the Employee's employment is terminated by the Employee for Good Reason (or in
the event UDC breaches this Agreement by termination of Employee without the
notice required under Section 5 or without Cause under Section 7), then UDC
shall amend at least one-half of all UDC stock options held by him and all
restricted,stock awards made to him (whether issued subject to forfeiture or to
be issued when and if they become vested) so as to (a) cause to vest,
immediately prior to the date of such Change in Control or termination of
employment, all such then invested stock options and restricted stock awards,
and (b) provide Employee 90 days to exercise such options (or such greater
period as may have been provided in the terms of such options). The
Compensation Committee of UDC, in place prior to the "Change of Control," will
have the ability to cause more than one-half of these options to vest. Such
determination will be made at the sole discretion of the Compensation
Committee. In addition, UDC will consistent with all applicable laws and
regulations, use its reasonable efforts to assist Employee in securing
independent third party financing of the funds required by employee to exercise
all vested but unexercised stock options held by him. If such financing is not
so obtained by Employee, then UDC shall loan to Employee the funds required by
Employee to exercise such options, which loan shall be repayable one year from
the date made, will be secured by UDC's common stock purchased upon exercise of
such options and will bear interest at the prime rate (floating) of Bank One -
Texas, N.A. To the extent that UDC refuses or is unable to comply with the
provisions of Section 9(a) hereof, the time period contemplated in Section 9(b)
shall commence on the date UDC complies with the provision of said Section
9(a).

         10.     CERTAIN REDUCTION OF PAYMENTS BY UDC.

                 (a)      Notwithstanding anything to the contrary in Sections
8 and 9 of this Agreement, in no event shall a Stock Option become immediately
exercisable or the restrictions relating to Restricted Stock terminate upon the
Employee's Termination if such acceleration would (i) cause any payment made to
the Employee, whether pursuant to the terms of this Agreement or otherwise (a
"Payment") to constitute an "excess parachute payment" within the meaning of
Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), or
(ii) disqualify the transaction constituting the Change of Control from being
accounted for as a "pooling of interests" within the meaning of APB No. 16,
which would qualify for such accounting treatment in the absence of such
acceleration (the "Disqualification"). In the event acceleration of any Option
Rights would cause any Payment to constitute an excess parachute payment, or
would cause a Disqualification, the Compensation Committee of the UDC Board of
Directors shall select the Stock Options which shall remain unexercisable so
that no Payment shall constitute an excess parachute payment and/or no
Disqualification shall occur. Any Stock Options which remain unexercisable upon
the Employee's Termination by reason of this Section 10(a) shall become
exercisable as set forth in Section 10(b) below.

                 (b)      In the event that any Stock Option which is
outstanding on the Employee's Termination has not become exercisable because of
the application of this Section 10, such Stock Option will become exercisable
in such manner and at such times as the Stock Option would have become
exercisable if the Employee had not terminated employment, and the portion of
any such Stock Option which becomes exercisable pursuant to this Section 10(b)
shall remain exercisable until the earlier of the date which is 90 days
following the date on which the Stock Option first becomes exercisable or the
original expiration date of the Stock Option.

         11. NON-COMPETITION AND CONFIDENTIALITY.

                 (a)      NON-COMPETITION. Employee recognizes and understands
that in performing the responsibilities of his employment, he will occupy a
position of fiduciary trust and confidence, pursuant to which he will develop
and acquire experience and knowledge with respect to UDC's business. It is the
expressed intent and agreement of Employee and UDC that such knowledge and
experience shall be used exclusively in the furtherance of the interests of UDC
and not in any manner which would be detrimental to UDC's interests. Employee
further understands and agrees that UDC conducts its business within a
specialized market segment throughout the United States, and that it would be
detrimental to the interests of UDC if Employee used the knowledge and
experience which he currently possesses or which he acquires pursuant to his
employment hereunder for the purpose of directly or indirectly competing with
UDC, or for the purpose of aiding other persons or entities in so competing
with UDC, anywhere in the United States. Employee therefore agrees that so long
as he is employed by UDC and for a period of the greater of (i) one year from
the date of notification by employee of termination (ii) the time Employee is
receiving a salary or severance payments or (iii) the time granted under
Section 9 to Employee to exercise stock options if options are exercised or
(iv) such time as UDC is loaning money or has a loan outstanding to Employee,
unless Employee first secures the written consent of UDC, Employee will not
directly or indirectly invest, engage or participate in or become employed by
any entity in direct or indirect competition with UDC's business (which shall
include the ownership and/or operation of managed dental plans) anywhere in the
United States, or contract to do so. These non-competition provisions are not
to be construed to prohibit Employee from being employed in the health care
industry, but rather to permit him to be so employed so long as such employment
does not involve Employee's direct or indirect participation in a business
which is the same or similar to UDC's business (as defined above). In the event
that the provisions of this Section 11 should ever be deemed to exceed the
time or geographic limitations permitted by applicable laws, then such
provisions shall be reformed to the maximum time or geographic limitations
permitted by applicable laws.

                 (b) REMEDIES. Employee acknowledges that the restrictions 
contained in Section 10(a), in view of the nature of the business in which UDC
is engaged, are reasonable and necessary to protect the legitimate interests of
UDC. Employee understands that the remedies at law for his violations of any of
the covenants or provisions of Section 10(a) will be inadequate, that such
violation will cause irreparable injury within a short period of time, and that
UDC shall be entitled to preliminary injunctive relief against such violation.
Such injunctive relief shall be in addition to, and in no way in limitation of,
any and all other remedies UDC shall have in law and equity for the enforcement
of those covenants and provisions.

         12.     GENERAL PROVISIONS.

                 (a)      NOTICES. Any notice to be given hereunder by either
party to the other may be effected by personal delivery, in writing or by mail,
registered or certified, postage prepaid with return receipt requested. Mailed
notices shall be addressed to the parties at the addresses set forth below, but
each party may change his or its address by written notice in accordance with
this Section 12(a). Notice deleted personally shall be deemed communicated as
of the actual receipt; mailed notices shall be deemed communicated as of three
days after mailing.

unenforceable, the remaining provisions shall, nevertheless, continue in full
force and without being impaired or invalidated in any way.

equity is necessary to enforce or interpret the terms of this Agreement, the
prevailing party shall be entitled to reasonable attorneys' fees, costs and
necessary disbursements in addition to any other relief to which he or it may
be entitled.

of and bind the parties hereto and their respective legal representatives,
successors and assigns.

and  all other Agreements, either oral or in writing, between the parties hereto
with respect to employment of Employee by UDC and contains all of the covenants
and agreements between the parties with respect to such employment. Each party
to this Agreement acknowledges that no representations, inducements or
agreements, oral or otherwise, have been embodied herein, and no other
agreement, statement or promise not contained in this Agreement shall be valid
or binding. Any modification of this Agreement will be effective only if it is
in writing signed by the party to be charged.

Agreement as of the date first written above.

                       EXECUTIVE INCENTIVE PLAN FOR 1996

WILLIAM H. WILCOX

Bonus - Your bonus plan will be designed to yield 80% to 100% of salary. For
calendar year 1996 you will be on the same bonus plan as that of Jim Kingston,
see attached. This plan is designed to yield $170,000 for the whole year, and
we anticipate that it will be very close to that figure. You will receive the
full-year calculated amount even though you will be actively employed for only
about eight months. Thus, the bonus for this year should result in at least 80%
of your salary earned for the year. 

<PAGE>   2
                      EXECUTIVE INCENTIVE PLAN FOR 1996


The plan consists of three components and covers JAMES B. KINGSTON, PRESIDENT,
CEO:

                        Financial    Membership    MBOs


The incentive payment will be made after the audited results for the year are
completed to those executives who are employed by United Dental Care at the
time payment is made.

FINANCIAL

The base of your 1995 bonus will be fully-diluted earnings per share of $0.90.
For each 1/10 of a cent above $0.90 EPS, you will earn $1,360. The maximum to be
paid in February, 1997 will be $68,000 under this category. Any excess above
$68,000 will be paid at the rate of $15,000/year starting in February, 1998.
Any extraordinary or non-recurring items included in earnings may be excluded
by the Committee from the computation of your bonus.

MEMBERSHIP

The base for your bonus is 908,000 commercial prepaid members in December,
1996. Commercial prepaid members exclude low option members and indemnity
members. Base membership represents an increase of approximately 14% over the
December, 1995 membership. For each commercial prepaid member above 908,000 in
December, 1996, you will earn $0.89 per member. The Committee will make an
adjustment for any members acquired by acquisition and/or any members lost
through sales.

MBOs

responsibilities, your MBOs will include RETAINING KEY EXECUTIVES; IMPROVING
