                               PROSPECTUS SUMMARY
 
     Young Innovations, Inc. was incorporated in July 1995 to serve as the
parent corporation for Young Dental Manufacturing Company ("Young Dental"),
founded at the turn of the century, and Lorvic Holdings, Inc. ("Lorvic") and its
operating subsidiary, The Lorvic Corporation, founded in 1953; Lorvic was
acquired by Young Dental in May 1995. Denticator International, Inc.
("Denticator") was acquired by Young Dental in July 1996. Young Dental
International, Inc. ("YDI") was organized as an indirect, wholly-owned
subsidiary in February 1996 to serve as a foreign sales corporation. Unless
otherwise indicated, all references in this Prospectus to the "Company" include
Young Dental, YDI, Lorvic and Denticator and all information is adjusted to
reflect the 1.2 for one stock split of the Common Stock to be effected in the
form of a stock dividend prior to completion of the Offering and assumes no
exercise of the Underwriters' over-allotment option. The following summary is
qualified in its entirety by the detailed information and the Consolidated
Financial Statements of the Company, Lorvic and Denticator, including the Notes
thereto, included elsewhere in this Prospectus. With respect to information
stated on a pro forma basis for 1996, such information includes the results of
operations of Denticator as if the acquisition occurred on January 1, 1996.
 
                                  THE COMPANY
 
     The Company is a leading designer, manufacturer and marketer of single-use
supplies, autoclavable instruments and other products used by dental
professionals, primarily in preventive dentistry and infection control. The
Company has a leading market share in certain segments of the preventive
dentistry market which it believes is due to its (i) longstanding reputation for
high quality, innovative and reliable products; (ii) widespread name recognition
and ability to leverage the Young and Denticator brands; and (iii) consummation
of strategic acquisitions. Through the successful implementation of the
Company's business strategy and the acquisitions of Lorvic and Denticator, the
Company's net sales and income from operations have grown at compound annual
rates of 21.4% and 30.7%, respectively, from 1992 through 1996.
 
     The Company's disposable and metal prophy angles, cups and brushes
(collectively, "Prophy Products"), which are integral components used in the
cleaning and polishing of teeth by dental professionals, represented 76.9% of
the Company's pro forma net sales in 1996. The Company's branded Prophy Products
currently have an estimated domestic market share of 53%, up from 22% in 1990.
Additionally, the Company has developed and acquired aspiration and infection
control products, as well as complementary preventive products such as pastes,
fluorides and fluoride applicators.
 
     The Company markets its full line of products to dental professionals
worldwide through a network of medical and dental product distributors. The
Company actively supports its distributor relationships through Company sales
personnel in the United States, independent sales representatives in Canada and
exclusive sales representatives in 13 countries outside of North America. The
Company also uses non-exclusive distributors to service markets in 40 other
countries. All major distributors of dental products in North America sell the
Company's products, including Patterson Dental Company ("Patterson"), Henry
Schein, Inc. ("Schein"), Sullivan Dental Products, Inc. ("Sullivan") and H. Meer
Dental Supply Company, Inc. ("Meer"). The Company's product development,
manufacturing and marketing capabilities and its relationships with distributors
allow the Company to provide a broad range of high quality, innovative and
reliable products to dental professionals. Additionally, these capabilities and
relationships enable the Company to quickly and efficiently offer new products
or product extensions to its existing customer base and new markets.
 
     The Company's objective is to profitably establish the number one or two
market share position for professional dental products in each of the market
segments in which it competes. The Company strives to achieve its objective by
enhancing and leveraging its name recognition and reputation; augmenting its
proprietary manufacturing capabilities with additional automation, capacity and
technology in order to maintain its low cost structure; and expanding its
established lines of single-use products which generate a significant stream of
recurring revenues and cash flow. The Company believes that its gross and
operating profit margins of 55.6% and 27.3% of 1996 pro forma net sales,
respectively, are the result of the successful implementation of these
strategies. The Company plans to capitalize on its established market position
by (i) pursuing strategic acquisitions of complementary businesses, product
lines and key technologies; (ii) actively developing new dental products and
product lines; and (iii) pursuing targeted international expansion.

     The Company's established position in the professional dental products
industry has enabled it to acquire successfully Lorvic in May 1995 and
Denticator in July 1996. The Lorvic acquisition added complementary lines of
aspiration and infection control products, as well as complementary preventive
products such as pastes, fluorides and fluoride applicators. The Denticator
acquisition built on the Company's market position by adding Prophy Product
lines aimed at the price sensitive segment of the market, which Young Dental
traditionally had not targeted.
 
     Preventive dentistry, including regular professional cleaning and polishing
of teeth ("prophy" or "prophylaxis"), helps to reduce the incidence of cavities,
gingivitis and periodontal disease and, due to its cost effectiveness, is
increasingly emphasized by private dental insurers, managed care providers and
consumers. Based on data compiled by the Health Care Financing Administration
("HCFA"), total spending on dental products and services increased from $31.6
billion to $45.8 billion from 1990 to 1995, or 7.7% per annum, and is estimated
to increase by 5.6% per annum from 1995 to 2005. The Company believes that the
professional dental products market will continue to be influenced by (i)
increased emphasis on preventive dentistry and infection control; (ii) favorable
demographic trends, including the increasing retention of natural teeth; and
(iii) growth in international markets, including Europe, South America, Central
America and the Pacific Rim. Heightened public awareness and increased
governmental regulations and guidelines regarding infection control have
resulted in increased usage of single-use products, products which can be
effectively sterilized and products used in the sterilization process. In 1996,
single-use products represented 92.9% of the Company's pro forma net sales.
 
     The Company believes that the dental industry is presently undergoing
consolidation at three different levels. Dental service providers are combining
as dental practice management companies acquire specialty and general dental
practices. Professional dental product distributors are also undergoing
consolidation as evidenced by Schein recently announcing its agreement to
acquire Sullivan. The professional dental product manufacturing industry is
highly fragmented with over 400 companies, many of which are small in size. The
Company believes that many small manufacturers will be at an increasing
disadvantage in the marketplace due to limited manufacturing and distribution
resources, increasing regulatory requirements and pricing pressures resulting
from the consolidation of distributors and dental service providers. As a
result, the Company anticipates increasing consolidation among manufacturers and
believes it is well positioned to make additional acquisitions due to its
acquisition experience and approach, name recognition, manufacturing
capabilities and established distribution network.
 
     The Company is a Missouri corporation with its principal executive office
located at 13705 Shoreline Court, Earth City, Missouri 63045, located in the St.
Louis, Missouri metropolitan area; its telephone number is (314) 344-0010.

- ---------------
(1) On July 22, 1996, the Company acquired Denticator. The income statement data
    for the year ended December 31, 1996, include results of operations for
    Denticator from July 22, 1996, through December 31, 1996. The balance sheet
    data as of December 31, 1996, include Denticator as of that date.
 
(2) Pro forma to give effect to (i) the acquisition of Denticator, including the
    incurrence of additional indebtedness related thereto as if the acquisition
    was completed on January 1, 1996; (ii) the sale of Common Stock offered
    hereby, as if the Offering was completed on January 1, 1996; and (iii) the
    application of $18.3 million of the net proceeds of the Offering to repay
    all indebtedness of the Company which would have been outstanding as of
    January 1, 1996. Pro forma earnings per share assumes 4,444,003 weighted
    average shares outstanding for 1996 plus 1,830,000 shares, representing
    those shares of Common Stock offered hereby at an assumed initial public
    offering price of $11.00 per share, sufficient to repay $18.3 million of
    indebtedness which would have been outstanding as of January 1, 1996. The
    pro forma information is not necessarily indicative of the results that
    actually would have been achieved if the Denticator acquisition had been
    consummated on January 1, 1996, or that may be achieved in the future. See
    "Use of Proceeds" and "Young Innovations, Inc. and Denticator International,
    Inc. Unaudited Pro Forma Financial Information."
 
(3) Until February 28, 1993, Young Dental had elected to be treated as an S
    Corporation for income tax purposes. As an S Corporation, its earnings were
    included in the personal tax returns of the stockholders of Young Dental and
    no income tax provision was recorded by Young Dental through February 28,
    1993. Effective March 1, 1993, Young Dental terminated its S Corporation
    status and became a taxable entity. Assuming Young Dental was a C
    Corporation, the estimated additional pro forma provision for income taxes
    was $869,000 for 1992 and $368,000 for 1993, assuming an income tax rate of
    37.0%.
 
(4) The Company plans to retire substantially all of its outstanding
    indebtedness using a portion of the net proceeds from the Offering. Assuming
    the Company's revolving line of credit and long-term borrowings were retired
    as of January 1, 1996, supplementary earnings per share would be $0.31 and
    $0.36 for the six months ended June 30, 1996, and 1997, respectively,
    reflecting the elimination of interest expense, net of income taxes, of
    $265,000 for 1996 and $373,000 for 1997. Supplementary earnings per share
    assumes 4,450,210 and 4,409,728 weighted average shares outstanding for the
    six months ended June 30, 1996 and 1997, respectively, plus 980,000 and
    1,480,000 shares, representing those shares of Common Stock sold at an
    assumed initial public offering price of $11.00 per share, and the
    application of the net proceeds therefrom sufficient to retire $9.6 million
    and $14.7 million of average outstanding borrowings for the six months ended
    June 30, 1996 and 1997, respectively.
 
(5) Adjusted to give effect to the sale of 2,000,000 shares of Common Stock
    offered by the Company hereby and the application of the estimated net
    proceeds therefrom. See "Use of Proceeds."
 
(6) Net working capital (deficit) represents current assets less current
    liabilities excluding current maturities of long-term debt and the Company's
    revolving line of credit. Net working capital (deficit) as of December 31,
    1993, includes $3.6 million of notes payable to stockholders related to
    distributions of S Corporation earnings that were paid in 1994.

                                  RISK FACTORS
 
     Prospective investors should carefully consider the following risk factors,
in addition to the other information set forth in this Prospectus, in evaluating
the Company and its business before purchasing shares of the Common Stock
offered hereby. This Prospectus contains certain forward-looking statements that
involve risks and uncertainties. Future events and the Company's actual results
could differ materially from those contemplated by such forward-looking
statements. It should be recognized that risks, including those set forth below,
may be significant, presently or in the future, and may materially affect the
Common Stock or the Company.
 
COMPETITION
 
     The markets for the Company's products are highly competitive. The Company
believes that the principal competitive factors in all of its markets are
product features and reliability, name recognition, distribution network,
customer service and, to a lesser extent, price. The relative speed with which
the Company can develop, complete testing of, obtain regulatory approval for and
sell commercial quantities of new products is also an important competitive
factor. Failure of the Company to offer products which either contain features
similar to or more desirable than products offered by its competitors or, in
certain cases, to meet the prices offered by its competitors, could have a
material adverse effect on the business, financial condition and results of
operations of the Company. Some of the Company's competitors have greater
financial, research, manufacturing and marketing resources than the Company. The
Company's inability to compete effectively against existing or future
competitors could result in a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Competition."
 
DEPENDENCE ON KEY DISTRIBUTORS; CONSOLIDATION OF KEY DISTRIBUTORS AND DENTAL
SERVICE PROVIDERS
 
     Patterson, Schein and Sullivan, three distributors of the Company's
products, accounted for 16.5%, 15.7% and 10.3% of the Company's net sales for
the six months ended June 30, 1997, respectively, and 17.9%, 19.1% and 7.7% of
the Company's net sales for the year ended December 31, 1996, respectively.
Increasingly, there has been consolidation of dental and medical products
distributors and dental service providers. In August 1997, Schein announced it
had agreed to acquire Sullivan; Schein and Sullivan collectively accounted for
26.0% and 26.8% of the Company's net sales for the six months ended June 30,
1997 and for the year ended December 31, 1996, respectively. The inability or
unwillingness of any of these distributors to continue to purchase the Company's
products could adversely affect the Company's business, financial condition and
results of operations. Additionally, as distributors and dental service
providers consolidate and become larger, their ability to negotiate more
favorable terms for the Company's products, including lower prices, may
increase. See "Business -- Marketing and Distribution."
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
     In pursuing its acquisition strategy, the Company will face risks commonly
encountered with growth through acquisitions. These risks include the incurrence
of significantly higher than anticipated capital expenditures and operating
expenses, disruption to the Company's ongoing business, dissipation of the
Company's management resources, failure to assimilate the operations and
personnel of acquired companies, failure to maintain uniform standards, controls
and policies and impairment of relationships with employees and customers as a
result of changes in management. There can be no assurance that the Company will
be successful in overcoming these risks or any other problems encountered with
acquisitions, including the Company's acquisitions of Lorvic and Denticator. To
the extent the Company does not successfully avoid or overcome the risks or
problems related to acquisitions, the Company's results of operations and
financial condition could be adversely affected. Future acquisitions also will
have a significant impact on the Company's financial position and capital needs.
Acquisitions could include significant goodwill and intangible assets, resulting
in substantial amortization charges to the Company that may reduce stated
earnings following such acquisitions. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business -- Growth
Strategy."

<PAGE>   8
 
AVAILABILITY OF ACQUISITION CANDIDATES; NEED FOR ADDITIONAL CAPITAL
 
     The Company's ability to grow through acquisitions will be dependent upon
(i) the availability of suitable acquisition candidates at an acceptable cost;
(ii) the Company's ability to compete effectively for available acquisition
candidates; and (iii)the availability of capital to complete acquisitions. The
Company intends to finance such acquisitions with cash generated from
operations, the incurrence or assumption of indebtedness and issuances of Common
Stock, as appropriate. Using cash to finance acquisitions could substantially
limit the Company's financial flexibility, using debt could result in financial
covenants that limit the Company's operating and financial flexibility and using
Common Stock may result in significant dilution of the interest in the Company
of the stockholders at that time. There can be no assurance that the Company
will be able to obtain additional capital on acceptable terms. If the Company is
unable to obtain additional capital on acceptable terms, the Company's
acquisition activities may be limited. To the extent the Company is limited in
its ability to make acquisitions for any reason, the Company's growth, financial
condition and results of operations could be adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and "Business -- Growth
Strategy."
 
MANAGEMENT OF GROWTH
 
     The Company has grown significantly in recent years and is expected to
continue to grow through acquisitions and internal growth. Management has
expended, and expects to continue to expend, significant time and effort in
evaluating, completing and integrating acquisitions and supporting internal
growth, including product development activities. There can be no assurance that
the Company's systems, procedures and controls will be adequate to support the
Company's operations as they expand. Any future growth also will impose
significant added responsibilities on members of senior management, including
the need to identify, recruit and integrate new senior level managers and
executives. There can be no assurance that such additional management will be
identified and retained by the Company. Any inability by the Company to manage
its growth or to attract and retain additional qualified management could result
in a material adverse effect on the Company's financial condition and results of
operations. See "Business -- Growth Strategy."
 
TECHNOLOGICAL CHANGE RESULTING IN PRODUCT OBSOLESCENCE; DEPENDENCE ON NEW
PRODUCTS
 
     The market for the Company's products is characterized by frequent product
improvements, evolving technology and the development of new products, including
increasingly effective preventive dental products designed for home use. The
development of new, improved or alternative methods for performing prophylaxis
treatments could render obsolete or reduce the need for certain of the Company's
products, which would have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the Company's future
growth and profitability are dependent upon its timely ability to continue to
develop new and improved products. There can be no assurance that the Company
will be able to develop such new or improved products in a timely manner or that
such new or improved products will achieve market acceptance. See "Business --
Product Development."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is substantially dependent upon the continued services of
certain key employees, including George E. Richmond, President and Chief
Executive Officer, Michael W. Eggleston, Vice President, Treasurer and Chief
Financial Officer, Richard G. Richmond, Secretary of the Company and President
of Young Dental, and Jose L. Mendoza, President and Chief Executive Officer of
Denticator. The loss of the services of any one of these individuals could have
a material adverse effect on the Company's business, financial condition and
results of operations. The Company does not maintain any "key man" insurance
policies on its key employees. Additionally, the future success of the Company
will depend, among other factors, on the Company's ability to continue to hire
and retain the necessary qualified technical and managerial personnel. The
Company competes for such personnel with numerous other companies, academic
institutions and other organizations. See "Management."
 
                                        7
<PAGE>   9
 
CHANGE IN MARKETING STRATEGY
 
     The Company has traditionally marketed its products in the United States
through independent sales representatives and a small number of Company sales
personnel. In July 1997, the Company terminated contracts with all of its
independent sales representatives in the United States and increased the size of
its employee sales force in order to refocus its sales efforts. The Company's
sales could be adversely affected by these changes, particularly in the early
stages of implementation of the new sales strategy. The fixed costs associated
with the Company's sales personnel may exceed the variable costs associated with
independent sales representatives who were compensated solely on a commission
basis. All of these factors could have a material adverse effect on the
Company's business, financial condition and results of operations. See "Business
- -- Marketing and Distribution."
 
LIMITED PROTECTION OF INTELLECTUAL PROPERTY; RISK OF INFRINGEMENT
 
     The Company's success is dependent upon its patented and proprietary
technologies. In addition to the Company's patents and pending patent
applications, the Company relies upon copyright, trademark and trade secret laws
and licenses and confidentiality and non-disclosure agreements to protect its
intellectual property and proprietary technology. There can be no assurance that
the steps taken by the Company to protect its intellectual property or
proprietary technology will be adequate or enforceable to prevent
misappropriation. In addition, the cost of prosecuting and defending such
actions can be significant and have a material adverse effect on the Company's
business, financial condition and results of operations. In September 1995,
judgment was entered in the Federal District Court for the Eastern District of
Missouri holding two of the Company's patents on its original disposable prophy
angle to be invalid. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview" and "Business -- Product
Development and -- Legal Proceedings."
 
GOVERNMENT REGULATION
 
     The development, manufacture and marketing of the Company's products are
subject to extensive and rigorous regulation by the United States Food and Drug
Administration (the "FDA") and by other governmental agencies and relevant
foreign agencies. Although the Company's current products are sold in the United
States under 510(k) clearances, over-the-counter ("OTC") drug monographs, and
exemptions from FDA drug and device clearance and approval requirements, the
process of obtaining and maintaining FDA and other required regulatory approvals
for dental device and related products is generally lengthy and expensive, and
the outcome is often unpredictable. There can be no assurance that the Company's
current market clearances can be maintained or that approvals will be granted
for future products on the basis of 510(k) clearances or that products can be
marketed under an OTC monograph or exemptions to FDA approval requirements. The
regulatory process may delay the marketing of new products for lengthy periods,
may result in substantial additional costs and may provide advantages to certain
competitors. Moreover, regulatory approvals, if granted, may include significant
limitations on the indicated uses for which a product may be marketed. The FDA
also actively regulates the uses for which products may be promoted and the
claims that may be made in promotional materials.
 
     The Company is also subject to FDA Quality System Requirements and Good
Manufacturing Practices and extensive recordkeeping and reporting requirements
for device and drug product sales in the United States. The Company's
manufacturing facilities are subject to periodic inspections by United States
federal agencies, as well as state and local agencies. The Company contracts for
the assembly of approximately 72% of its disposable prophy angles in Mexico with
third parties. While the Company frequently audits these operations, there can
be no assurance that they will continue to meet FDA Quality System Requirements
and Good Manufacturing Practices. Failure to comply with applicable regulatory
requirements can result in, among other things, import detentions, fines, civil
penalties, suspensions or losses of approvals, recalls or seizures of products,
operating restrictions and criminal prosecutions.
 
                                        8
<PAGE>   10
 
PRODUCT LIABILITY; RISK OF RECALL
 
     The Company is subject to potential product liability claims as a result of
the design, manufacture and marketing of its products. Claims alleging product
liability may involve large potential damages and significant defense costs. The
Company believes that it currently maintains adequate insurance coverage for
such claims, but there can be no assurance that the Company's insurance coverage
will be adequate or that all such claims will be covered by the Company's
insurance. While the Company has been able to obtain product liability insurance
in the past, such insurance varies in cost, can be difficult to obtain and may
not be available in the future on terms acceptable to the Company. A product
liability claim could adversely affect the Company's reputation. A successful
claim against the Company in excess of the available insurance coverage could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     In addition, the FDA and similar governmental authorities in other
countries have the authority to require the recall of products in the event of
material deficiencies or defects in design or manufacture. Although the Company
adheres to strict quality control procedures, a government mandated or voluntary
product recall by the Company could occur as a result of material deficiencies,
component failures, manufacturing errors or design defects caused by the Company
or any of its suppliers. Any recall of products could have a material adverse
effect on the Company's reputation, business, financial condition and results of
operations.
 
POSSIBLE REDUCTION OR ELIMINATION OF DENTAL INSURANCE COVERAGE
 
     The cost of dental care, including preventive dental care, is increasingly
funded by third party payors, including private and corporate dental insurance
plans. A reduction or elimination of insurance coverage for dental care
generally, or for preventive dental care in particular, would adversely affect
the Company's ability to sell its products and have a material adverse effect on
the Company's business, financial condition and results of operations.
 
CONCENTRATION OF OPERATIONS IN SINGLE FACILITY
 
     The Company currently has three operating facilities, one in Earth City,
Missouri, one in Brownsville, Texas and one in Sacramento, California. However,
a substantial majority of the Company's administrative, manufacturing,
marketing, customer service, product development, information systems, product
ordering and product shipping activities are conducted from the Earth City
facility. While Earth City has not been affected by floods in recent years,
including the record floods in the summer of 1993, it is located in a former
flood plain of the Missouri River. The Company believes that dikes protecting
Earth City are sufficient to prevent flooding in the future. However, there can
be no assurance that future floods will not affect the Company's Earth City
facility and cause interruption of the Company's business. Although the Company
carries business interruption insurance and believes that in an emergency it
could continue to operate by moving a part of its production to its Texas and
California facilities and contracting with third parties to fabricate certain
products, a substantial interruption of business at the Company's Earth City
facility, whether resulting from flood, fire or other causes, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Properties."
 
CONCENTRATION OF SUPPLIERS
 
     The Company has two suppliers for the rubber used to produce its prophy
cups. The Company relies on proprietary rubber formulations that were
independently developed and are owned by these suppliers. If the Company is no
longer able to obtain its rubber or the formula from either supplier, it would
be forced to obtain a rubber formulation from another source. There can be no
assurance that another supplier would be able to develop an acceptable
formulation or be able to provide the Company with sufficient amounts of rubber.
If the Company is unable to obtain a satisfactory rubber formulation, the
quality of its prophy cups could be negatively impacted and the Company could
suffer a loss of reputation and a decline in sales of Prophy Products. These
factors could have a material adverse effect on the Company's business,
financial condition and results of operations.

<PAGE>   11
 
CONTROL BY EXISTING STOCKHOLDERS
 
     Upon completion of the Offering, the Company's President and Chief
Executive Officer, George Richmond, will own or have the right to vote an
aggregate of 51.4% of the outstanding shares of Common Stock (49.1% if the
Underwriters' over-allotment option is exercised in full). As a result, Mr.
Richmond will be in a position to control the management and policies of the
Company, including, but not limited to, electing or removing the Company's Board
of Directors and controlling any other actions requiring stockholder approval.
See "Certain Transactions," "Principal Stockholders" and "Description of Capital
Stock."
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
     Purchasers of Common Stock will suffer an immediate and substantial
dilution in the net tangible book value per share from the initial public
offering price. See "Dilution."
 
NO PRIOR PUBLIC MARKET; POTENTIAL VOLATILITY OF STOCK PRICE
 
     Prior to this Offering, there has been no public market for the Common
Stock, and there can be no assurance that a trading market will develop and
continue after the Offering or that the market price of the Common Stock will
not decline below the initial public offering price. The initial public offering
price will be determined through negotiations between the Company and
representatives of the Underwriters and may not be indicative of the market
price of the Common Stock following the Offering. The stock market has, in the
past, experienced price and volume fluctuations that at times have been
unrelated to corporate operating performance. Such market volatility may
adversely affect the market price of the Common Stock. Additionally, other
factors such as variations in the Company's financial results, announcements of
technological innovations or new products by its competitors, government
regulation, developments with respect to patents, proprietary rights or
litigation, and general market conditions may have a material adverse effect on
the market price of the Common Stock. See "Underwriting."
 
DIVIDEND POLICY
 
     The Company currently anticipates that, after completion of the Offering,
all of its earnings will be retained for development and expansion of the
Company's business and does not anticipate paying any cash dividends on the
Common Stock in the foreseeable future. See "Dividend Policy."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Common Stock in the public market following
the Offering could adversely affect the market price of the Common Stock. Upon
completion of the Offering, the Company will have 6,410,296 shares of Common
Stock outstanding. Of these shares, the 2,000,000 shares of Common Stock sold in
the Offering will be freely tradeable in the market, except for shares purchased
by "affiliates" of the Company which will be subject to the resale limitations
(excluding the holding period requirement) of Rule 144 under the Securities Act
of 1933, as amended (the "Act"). Substantially all of the remaining 4,410,296
shares may be sold immediately following the Offering subject to compliance with
the volume and manner of sale limitations of Rule 144. All of the officers,
Directors and stockholders of the Company and the Company have agreed not to
sell any of their shares of Common Stock for a period of 180 days after the date
of the Prospectus without the prior written consent of Robert W. Baird & Co.
Incorporated. See "Shares Eligible for Future Sale."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered hereby, after deducting the underwriting discount and
estimated offering expenses, are estimated to be approximately $20.0 million
($23.1 million if the Underwriters' over-allotment option is exercised in full),
assuming an initial public offering price of $11.00 per share. The Company
intends to use the proceeds (i) to repay borrowings of approximately $14.1
million under the Revolving Credit and Term Loan Agreement dated July 22, 1996
between the Company and NationsBank, N.A., as amended (the "Credit Agreement")
and (ii) for working capital and general corporate purposes, including making
strategic acquisitions. Indebtedness to be repaid under the Credit Agreement
includes a term loan maturing on December 1, 1999, which had an outstanding
principal balance of $9.4 million and bore interest at 8.1% per annum as of
August 15, 1997, and a revolving line of credit maturing on December 1, 1999,
which had an outstanding principal balance of $4.7 million and bore interest at
8.0% per annum as of August 15, 1997. Loans under the Credit Agreement were made
in July 1996 and used to acquire Denticator and repay other existing debt,
including debt incurred in connection with the Lorvic acquisition. As of the
date of this Prospectus, there are no agreements or understandings with respect
to specific acquisitions. Pending such uses, the Company will invest the net
proceeds from the sale of the Common Stock offered hereby in short-term,
investment-grade, interest-bearing marketable securities.
 
                                DIVIDEND POLICY
 
     The Company has not paid cash dividends on its Common Stock since its
inception. The Company currently intends to retain earnings for use in its
business and, therefore, does not anticipate paying any cash dividends in the
foreseeable future. Payment of cash dividends, if any, will be at the discretion
of the Company's Board of Directors and will be dependent upon the earnings and
financial condition of the Company and any other factors deemed relevant by the
Board of Directors and will be subject to any applicable restrictions contained
in the Company's then existing credit arrangements. In addition, the Credit
Agreement prohibits the payment of dividends without the bank's consent.

     The following table sets forth the consolidated cash and cash equivalents,
short-term debt and capitalization of the Company as of June 30, 1997 and as
adjusted to reflect (i) the sale of 2,000,000 shares of Common Stock offered
hereby at an assumed initial public offering price of $11.00 per share; (ii) the
application of the net proceeds therefrom; and (iii) the termination of certain
stockholder agreements that will eliminate the put rights related to shares of
puttable Common Stock. See "Use of Proceeds" and "Certain Transactions." The
table should be read in conjunction with the Company's Consolidated Financial
Statements and the Notes thereto included elsewhere in this Prospectus.

    is subject to agreements giving holders the right, and upon termination of
    employment the obligation, to sell their shares to the Company's majority
    stockholder or the Company at an appraised value. Upon consummation of the

    Denticator in July 1998 in connection with the Denticator acquisition. See

                                    DILUTION
 
     The Company's net tangible book value was $(6.3) million, or $(1.50) per
share, based on 4,208,300 shares of Common Stock outstanding as of June 30, 1997
(excluding 201,996 shares of puttable Common Stock). Net tangible book value per
share represents the amount of the Company's total tangible assets less its
total liabilities, divided by the total number of shares of Common Stock
outstanding. After giving effect to (i) the sale of the 2,000,000 shares of
Common Stock being offered hereby at an assumed initial public offering price of
$11.00 per share; (ii) the application of the estimated net proceeds therefrom;
and (iii) the elimination of all put rights related to 201,996 shares of
puttable Common Stock, the pro forma net tangible book value of the Company as
of June 30, 1997 would have been $15.3 million or $2.39 per share of Common
Stock. This represents an immediate increase in net tangible book value of $3.89
per share to existing stockholders and an immediate dilution of $8.61 per share
to new investors purchasing shares of Common Stock in the Offering. The
following table illustrates the per share dilution:

(1) Dilution is determined by subtracting pro forma net tangible book value per

    forma net tangible book value per share and the dilution per share to
    purchasers of the shares would be $2.74 and $8.26, respectively.

(1) On July 22, 1996, the Company acquired Denticator. The income statement data
    for the year ended December 31, 1996, include results of operations for
    Denticator from July 22, 1996, through December 31, 1996. The balance sheet

(2) Until February 28, 1993, Young Dental had elected to be treated as an S
    Corporation for income tax purposes. As an S Corporation, its earnings were
    included in the personal tax returns of the stockholders of Young Dental and
    no income tax provision was recorded by Young Dental through February 28,
    1993. Effective March 1, 1993, Young Dental terminated its S Corporation
    status and became a taxable entity. Assuming Young Dental was a C
    Corporation, the estimated additional pro forma provision for income taxes
    was $869,000 for 1992 and $368,000 for 1993, assuming an income tax rate of
    37.0%.
 
(3) The Company plans to retire substantially all of its outstanding
    indebtedness using a portion of net proceeds from the Offering. Assuming the
    Company's revolving line of credit and long-term borrowings were retired as
    of January 1, 1996, supplementary earnings per share would be $0.31 and
    $0.36 for the six months ended June 30, 1996, and 1997, respectively,
    reflecting the elimination of interest expense, net of income taxes, of
    $265,000 for 1996 and $373,000 for 1997. Supplementary earnings per share
    assumes 4,450,210 and 4,409,728 weighted average shares outstanding for the
    six months ended June 30, 1996 and 1997, respectively, plus 980,000 and
    1,480,000 shares, representing those shares of Common Stock sold at an
    assumed initial public offering price of $11.00 per share, and the
    application of the net proceeds therefrom sufficient to retire $9.6 million
    and $14.7 million of average outstanding borrowings for the six months ended
    June 30, 1996 and 1997, respectively.
 
(4) Net working capital (deficit) represents current assets less current
    liabilities excluding current maturities of long-term debt and the Company's
    revolving line of credit. Net working capital (deficit) as of December 31,
    1993, includes $3.6 million of notes payable to stockholders related to
    distributions of S Corporation earnings that were paid in 1994.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Prospectus contains certain forward-looking statements that are based
on the beliefs of the Company's management, as well as assumptions made by, and
information currently available to, the Company's management. Such statements
include those regarding successfully implementing and continuing the Company's
business strategies and growth strategies. Because such statements involve risks
and uncertainties, actual actions and strategies and the timing and expected
results thereof may differ materially from those expressed or implied by such
forward-looking statements, and the Company's future results, performance or
achievements could differ materially from those expressed in, or implied by, any
such forward-looking statements. Factors that could cause or contribute to such
material differences include, but are not limited to, those discussed under
"Risk Factors." The following presentation of management's discussion and
analysis of the Company's financial condition and results of operations should
be read in conjunction with the Company's Consolidated Financial Statements, the
Notes thereto and other financial information included elsewhere in this
Prospectus.
 
OVERVIEW
 
     Through its Young Dental and recently acquired Lorvic and Denticator
brands, the Company provides one of the broadest lines of supplies and
instruments to the preventive dentistry and infection control segments of the
professional dental products market.
 
     The Company's net sales have grown to $21.6 million in 1996 from $9.9
million in 1992, representing a compound annual growth rate of approximately
21.4%. The Company's growth has been driven by three principal factors: (i) the
successful introduction of a line of highly reliable disposable prophy angles;
(ii) the increase in its market share of metal prophy angles, cups and brushes;
and (iii) the acquisitions of Lorvic and Denticator. The Company's estimated
domestic share of the branded Prophy Products market has increased to 53% in
1996 from 22% in 1990, a significant portion of which is attributable to the
introduction of its line of disposable prophy angles, a maintenance free metal
prophy angle and several newly designed cups and brushes for its prophy angles.
Additionally, approximately 42.5% of the Company's pro forma net sales in 1996
resulted from new products introduced by Young Dental since 1990. The Company
has also benefited from growth in private label arrangements with certain of its
key distributors and from increased market share resulting from product
promotional activities, such as price promotions organized around industry
conventions, volume purchase rebate programs and national promotions targeted to
dental professionals. While the Company infrequently conducts national
promotions, it conducted such a promotion in the first quarter of 1997 which
increased net sales in that quarter by approximately $600,000 and decreased net
sales in the second quarter of 1997 by approximately $300,000, in each case as
compared to normalized levels, and which may continue to impact subsequent
quarters and comparisons with comparable future quarters. In addition, annual
rebate programs often result in higher fourth quarter net sales than in other
periods during the year.
 
     A principal component of the Company's growth strategy is to expand through
strategic acquisitions. On May 5, 1995, the Company acquired the common stock of
Lorvic for approximately $13.4 million. Lorvic provided the Company with lines
of aspiration, infection control and preventive dental products that directly
complement its strong position in Prophy Products. The Company borrowed $13.5
million to fund the Lorvic acquisition. On July 22, 1996, the Company acquired
the assets and liabilities of Denticator for approximately $7.6 million in cash,
and approximately $900,000 of Company products, of which $392,000 of such
products remain as of June 30, 1997 and are expected to be delivered within the
next 12 months. Denticator's line of popular priced disposable prophy angles
enabled the Company to extend its line of Prophy Products, now the broadest
Prophy Product offering available, and significantly increase its share of the
domestic Prophy Product market. The Company borrowed $16.5 million to fund the
Denticator acquisition and to repay debt incurred in connection with the Lorvic
acquisition. The Company intends to repay the entire outstanding balance of this
loan with a portion of the net proceeds from the Offering. Lorvic's and
Denticator's results of operations are included since the acquisition dates. The
acquisitions were accounted for using the purchase method of accounting,
resulting in goodwill of $11.6 million and $7.6 million, respectively, which are
being amortized over 40 years from the dates of the respective acquisitions.
 
                                       17

     The most significant components of the Company's cost of goods sold are
manufacturing overhead and material purchases. Due to the high level of
automation of the Company's manufacturing processes, it has been able to
maintain a relatively low level of direct labor, as a percentage of net sales.
Additionally, the Company maintains low direct labor costs by contracting for
the assembly of approximately 72% of its disposable prophy angles with third
party maquiladora operations located in Mexico. To further improve its gross
margin, the Company initiated manufacturing activities at Denticator in April
1997 by acquiring injection molding equipment for the production of Denticator's
disposable prophy angles. Previously, Denticator outsourced its injection
molding needs, which resulted in a lower gross margin than Young Dental's. See
"Certain Transactions." The Company believes its manufacturing strengths,
including certain proprietary molding and vulcanizing processes, provide it with
a competitive advantage and are key factors in its ability to generate a high
gross margin and operating profit margin which, in 1996, were 55.6% and 27.3% of
pro forma net sales, respectively.
 
     The Company's selling, general and administrative expenses ("SG&A") consist
of selling and marketing expenses, research and development expenses,
administrative expenses and goodwill amortization, among other expenses. Given
the Company's recent conversion in the United States from independent sales
representatives to Company employees, selling expenses will be primarily fixed
in the future as compared with the variable expense associated with its
independent sales representative organization. The Company believes this
conversion will result in reduced selling expense as a percent of net sales and
enable it to have more focused sales coverage of its domestic customers.
Goodwill amortization also represents an increasing component of selling,
general and administrative expenses as a result of the Company's use of purchase
accounting for the Lorvic and Denticator acquisitions. Additionally, as part of
an employment agreement with Denticator's President and Chief Executive Officer,
the Company agreed, subject to his continued employment, to deliver shares of
Common Stock of the Company having a value, in the aggregate, of $800,000 on
July 22, 1998. See "Management -- Employment Agreements." The Company is
amortizing the value of this deferred compensation by $100,000 per quarter, with
the final amortization to occur in the third quarter of 1998. During 1995,
litigation expense of $688,000 associated with the Company's patent infringement
lawsuit also represented a meaningful component of selling, general and
administrative expense.
 
     Other expenses include gain and loss on disposition of fixed assets, sale
of scrap and other miscellaneous income and expense items, all of which are not
directly related to the Company's principal business activities. In 1996, other
expenses included approximately $322,000 of deferred offering costs expensed as
a result of the Company withdrawing its registration statement in 1996 with
respect to its proposed public offering in 1995.

SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996
 
     Net Sales. Net sales increased $3.1 million, or 34.2%, to $12.1 million in
1997 from $9.0 million in 1996. Disposable prophy angle sales increased
approximately $2.7 million with approximately $2.6 million of the increase
attributable to the addition of Denticator disposable prophy angles. Sales of
Young branded disposable prophy angles increased by $300,000, but were offset by
a $200,000 decrease in sales of Young Dental's private label lines. Sales of the
Company's contra disposable prophy angles, a portion of branded disposable
prophy angles, increased approximately $93,000, or 33.3% in 1997 as compared to
1996. Sales of prophy cups and metal prophy angles for the period added
approximately $200,000 to net sales, representing an increase of 12.2% from
1996, and aspiration products contributed approximately $85,000 to the increase.
 
     Gross Profit. Gross profit increased $1.8 million, or 34.4%, to $7.1
million in 1997 from $5.3 million in 1996. The Company's gross margin remained
relatively steady at 58.7% of net sales in 1997 despite a lower gross margin
from Denticator's disposable prophy angles. The Company expects that its gross
margin will improve as a result of bringing Denticator's manufacturing
operations in-house. Gross profit benefited from increased sales of disposable
prophy angles by Denticator, which represented approximately $1.5 million of
such increase, and increased sales of metal prophy angles, cups and aspiration
products.
 
     Selling, General and Administrative Expenses. SG&A expenses increased $1.4
million, or 61.0%, to $3.7 million in 1997 from $2.3 million in 1996. As a
percent of net sales, SG&A expenses increased to 30.3% in 1997 from 25.3% in
1996. The Denticator acquisition added $1.1 million to SG&A of which
approximately $200,000 related to a deferred stock compensation agreement with
Denticator's President and Chief Executive Officer, which will end in July 1998
and $95,000 related to amortization of goodwill from the acquisition. In
addition, the Company incurred a $316,000 expense related to a first quarter
1997 national promotion to dental professionals.
 
     Income from Operations. Income from operations increased $429,000, or
14.2%, to $3.4 million in 1997 from $3.0 million in 1996.
 
     Interest Expense. Interest expense increased $182,000 to $602,000 in 1997
from $420,000 in 1996. The increase was due to the additional debt borrowed to
fund the acquisition of Denticator in July 1996.
 
                                       19

     Other Expense (Income). Other expense (income) decreased $273,000 to
$(3,000) in 1997 from $270,000 in 1996 primarily due to inclusion in 1996 of a
write-off of deferred initial public offering costs.
 
     Provision for Income Taxes. Provision for income taxes increased $195,000
to $1.1 million in 1997 from $884,000 in 1996.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
     Net Sales. Net sales increased $4.1 million, or 23.3%, to $21.6 million in
1996 from $17.5 million in 1995. Disposable prophy angle sales increased 30.4%,
or approximately $2.8 million, with the Denticator disposable prophy angle line
contributing approximately $2.4 million from the date of the acquisition. The
Company's contra disposable prophy angle, which was introduced in 1995,
continued to penetrate the disposable prophy angle market, increasing
approximately $500,000 in 1996. The increase in sales of the contra disposable
prophy angles partially offset slight decreases in sales of the Company's
traditional disposable prophy angle lines, prophy cups and metal prophy angles.
Aspiration and infection control products increased net sales by approximately
$623,000 and $384,000, respectively, in 1996 as compared to 1995.
 
     Gross Profit. Gross profit increased $2.0 million, or 19.7%, to $12.1
million in 1996 from $10.1 million in 1995. Gross margin decreased to 56.1% of
net sales in 1996 from 57.8% in 1995. Gross margin was negatively impacted by
lost production and inefficiencies during a major addition and renovation of the
Company's Earth City facility which consolidated two other St. Louis facilities.
The Denticator acquisition added approximately $1.2 million to gross profit, but
at a lower gross margin than Young branded disposable prophy angles. The
$800,000 balance of the increase in gross profit was primarily attributable to
the full year inclusion of Lorvic and an increase in sales of the contra
disposable prophy angle line.
 
     Selling, General and Administrative Expenses. SG&A expenses increased $1.3
million, or 28.8%, to $5.8 million in 1996 from $4.5 million in 1995. As a
percent of net sales, SG&A expenses increased to 26.8% in 1996 from 25.7% in
1995. The increase was primarily attributable to the addition of Denticator
which added $1.2 million to SG&A for 1996, including a one-time $290,000 signing
bonus and $176,000 of deferred stock compensation expense with Denticator's
President and Chief Executive Officer. SG&A also increased due to an additional
(i) amortization expense of $185,000 resulting from goodwill associated with the
partial year inclusion of Denticator and full year inclusion of Lorvic; (ii)
research and development expenses of $226,000 due to staff additions and
increased product development projects; (iii) dealer rebate programs of
$105,000; (iv) product sampling expenses of $77,000; and (v) commissions to
independent sales representatives of $71,000 due to higher sales. These
increases were offset by a $673,000 reduction in legal expenses in 1996 as
compared to 1995 when the Company's patent infringement lawsuit was being
litigated.
 
     Income from Operations. Income from operations increased $697,000, or
12.4%, to $6.3 million in 1996 from $5.6 million in 1995.
 
     Interest Expense. Interest expense increased $233,000 to $974,000 in 1996
from $741,000 in 1995. The increase was due to the additional debt borrowed to
fund the acquisition of Denticator in July 1996 and the full year inclusion of
interest expense from the acquisition of Lorvic which was acquired in May 1995.
 
     Other Expense. Other expense for 1996 included $322,000 from charges
related to inclusion of a write-off of deferred initial public offering costs.
 
     Provision for Income Taxes. Provision for income taxes decreased $89,000 in
1996 to $2.0 million.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Net Sales. Net sales increased $5.5 million, or 45.4%, to $17.5 million in
1995 from $12.0 million in 1994. Disposable prophy angle sales increased
approximately $1.8 million primarily attributable to increased sales of Young
branded disposable prophy angles in 1995 as compared to 1994. Sales of
disposable prophy angles in 1994 were adversely impacted due to a successful
national promotion to dental professionals in the fourth quarter of 1993. In the
second quarter of 1995, the Company introduced its contra disposable prophy
angle which contributed $185,000 to disposable prophy angle sales in 1995. Sales
of metal prophy angles,
 
                                       20
<PAGE>   22
 
along with prophy cups and brushes, increased approximately $331,000 in 1995 as
compared to 1994. In addition, significant sales increases occurred as a result
of the acquisition of Lorvic in May 1995, which added product lines such as
aspiration and infection control products, adding sales of $1.1 million and
$785,000 in 1995, respectively.
 
     Gross Profit. Gross profit increased $3.5 million, or 53.8%, to $10.1
million in 1995 from $6.6 million in 1994. Gross margin increased to 57.8% of
net sales in 1995 from 54.7% in 1994. The increase in gross margin was primarily
attributed to the increase in sales of disposable prophy angles and the addition
of new higher margin products as a result of the Lorvic acquisition. The
addition of Lorvic accounted for $1.9 million of the increase in gross profit
and the remaining $1.6 million was primarily due to increased sales of
disposable prophy angles.
 
     Selling, General and Administrative Expenses. SG&A expenses increased $1.4
million, or 46.7%, to $4.5 million in 1995 from $3.1 million in 1994. As a
percent of net sales, SG&A expenses increased to 25.7% in 1995 from 25.5% in
1994. The acquisition of Lorvic added $589,000 to SG&A in 1995, including
$184,000 of goodwill amortization expense. Professional fees increased $440,000
primarily due to legal expenses resulting from the trial of a patent
infringement lawsuit initiated by the Company. Research and development costs
increased $193,000, or 121.4%, as a result of additional staffing and product
development projects.
 
     Income from Operations. Income from operations increased $2.1 million, or
59.9%, to $5.6 million in 1995 from $3.5 million in 1994.
 
     Interest Expense. Interest expense increased $552,000 to $741,000 in 1995
from $189,000 in 1994. The increase was due to the additional debt borrowed to
fund the acquisition of Lorvic.
 
     Other Expense. There was no significant other expense in 1995 or 1994.
 
     Provision for Income Taxes. Provision for income taxes increased $774,000
to $2.0 million in 1995 from $1.3 million in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has financed its operations primarily through cash flow from
operating activities and, to a lesser extent, through borrowings under its
credit facilities. During the first six months of 1997, net cash flow from
operating activities was $2.4 million, compared to $2.3 million for the same
period in 1996. Net cash flow from operating activities in 1996 was $4.5
million, compared to $3.5 million in 1995.
 
     Capital expenditures for property, plant and equipment were $424,000 in the
first six months of 1997, compared to $682,000 for the same period in 1996. In
1996, capital expenditures increased significantly to $3.2 million compared to
$992,000 in 1995 primarily as a result of the expansion of the Earth City
facility which consolidated two other St. Louis facilities to that location. The
Company estimates capital expenditures for the last two quarters of 1997 and for
1998 will aggregate approximately $1.2 million. Consistent with the Company's
historical capital expenditures, future capital expenditures are expected to
include injection molding equipment, computer numeric controlled equipment and
upgrades to production machinery and data processing.
 
     Concurrent with the Denticator acquisition in July 1996, the Company
entered into a Credit Agreement, which, as amended, consists of a $12.0 million
term loan maturing on December 1, 1999 bearing interest at a per annum interest
rate of 0.25% above the prime rate of the lending bank in effect on any day or
at a LIBOR rate plus 2.5% for a set period through maturity collateralized by
all assets and subsidiary stock of the Company, together with a revolving loan
facility of $7.0 million which matures on December 1, 1999, with interest at the
prime rate of the lending bank minus 0.5%. The Company's Chief Executive Officer
has pledged 2,391,285 shares of Common Stock as additional collateral which will
be released upon repayment of borrowings under the Credit Agreement. The Credit
Agreement replaced a $13.5 million secured credit facility which had slightly
higher interest rates. In July 1996, the Company borrowed $16.5 million under
the Credit Agreement to fund the purchase of Denticator and to repay the prior
credit facility. On June 30, 1997, the outstanding balances under the Credit
Agreement aggregated $14.3 million, which balances will be repaid
 
                                       21
<PAGE>   23
 
with a portion of the net proceeds of the Offering. The Company's lending bank
has provided a written letter which indicates its strong interest in making
available to the Company, upon completion of the Offering, a five-year secured
revolving loan facility of $25.0 million bearing interest at the bank's prime
rate, subject to negotiation of final terms, including loan covenants and review
of financial information.
 
     The Internal Revenue Service ("IRS") examined Lorvic's federal income tax
returns for the years ended March 31, 1992 through 1995 and proposed
deficiencies in federal income taxes for those years in an aggregate amount of
$766,000 due to classification of certain intangible assets. Lorvic has filed
two petitions with the United States Tax Court contesting these proposed
deficiencies. The first of these petitions, which relates to the years ended
March 31, 1992 and 1993, is scheduled for trial in October 1997. In accordance
with the stock purchase agreement pursuant to which the Company acquired Lorvic
in May 1995, the previous stockholders of Lorvic are responsible for the
settlement of this matter to the extent of $700,000 held in an escrow fund,
together with earnings thereon, plus an additional $200,000 to cover any
interest and penalties related to such matters. While there can be no such
assurance, the Company believes the escrowed amounts will be sufficient to
satisfy these deficiencies in full for all affected years if required. See
"Certain Transactions."
 
     Anticipated internal cash flows, borrowings under the Company's existing
and anticipated credit facilities and the net proceeds of the Offering are
expected to provide sufficient liquidity for working capital needs, capital
expenditures and potential acquisitions through 1998.
 
NEW ACCOUNTING STANDARDS
 
     In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS
128"), which establishes standards for computing and presenting earnings per
share. SFAS 128 replaces the presentation of primary earnings per share with a
presentation of basic earnings per share. It also requires the dual presentation
of basic and diluted earnings per share on the face of the income statements for
all entities with complex capital structures and requires a reconciliation of
the numerator and the denominator of the basic and diluted earnings per share
computations. The Company is required to adopt the provisions of SFAS 128 during
the quarter ending December 31, 1997, and all prior earnings per share data
presented must be restated. The adoption of SFAS 128 is not expected to have a
significant impact on the Company's previously reported or prospective earnings
per share amounts.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income" ("SFAS 130"), which establishes
standards for reporting and displaying comprehensive income and its components.
The Company is required to adopt the provisions of SFAS 130 no later than the
quarter ending March 31, 1998. The adoption of SFAS 130 is not expected to have
a material effect on the Company's financial position or results of operations.

                                    BUSINESS
 
GENERAL
 
     The Company is a leading designer, manufacturer and marketer of single-use
supplies, autoclavable instruments and other products used by dental
professionals, primarily in preventive dentistry and infection control. The
Company has a leading market share in certain segments of the preventive
dentistry market which the Company believes is due to its (i) longstanding
reputation for high quality, innovative and reliable products; (ii) widespread
name recognition and ability to leverage the Young and Denticator brands; and
(iii) consummation of strategic acquisitions. Through the successful
implementation of the Company's business strategy and the acquisitions of Lorvic
and Denticator, the Company's net sales and income from operations have grown at
a compound annual rate of 21.4% and 30.7%, respectively, from 1992 through 1996.
 
     The Company's Prophy Products, which are integral components used in the
cleaning and polishing of teeth by dental professionals, represented
approximately 76.9% of the Company's pro forma net sales in 1996. The Company's
branded Prophy Products currently have an estimated domestic market share of
53%, up from 22% in 1990. Additionally, the Company has developed and acquired
aspiration and infection control products, as well as complementary preventive
products such as pastes, fluorides and fluoride applicators.
 
INDUSTRY BACKGROUND
 
     Based on data compiled by HCFA, total spending on dental products and
services increased from $31.6 billion to $45.8 billion from 1990 to 1995,
representing a compound annual growth rate of 7.7%. HCFA reported that this
aggregate domestic market represented approximately 4.6% of total health care
expenditures in 1995. HCFA has projected that dental expenditures will reach
$79.1 billion by the year 2005, representing a compound annual growth rate of
approximately 5.6%.
 
     The Company believes that the dental industry is presently undergoing
consolidation at three different levels. Dental service providers are combining
as dental practice management companies acquire specialty and general dental
practices. Professional dental product distributors are also undergoing
consolidation as evidenced by Schein announcing it has agreed to acquire
Sullivan. Similarly, the Company anticipates increasing consolidation among
manufacturers in the highly fragmented professional dental products industry.
 
     In recent years, there has been an increasing emphasis on dental health,
including preventive dentistry and infection control, which has led to an
increase in sales of dental supplies and equipment and which the Company
believes will result in continued growth due to the following factors:
 
     Increased Emphasis on Preventive Dentistry and Infection Control. There is
a general awareness in North America, the Scandinavian countries and certain
other parts of the world that preventive dentistry, including regular cleaning
and polishing of teeth, is effective in reducing the incidence of cavities,
gingivitis and periodontal disease, thereby enabling people to keep their
natural teeth longer, obtain cosmetic benefits and improve their oral health. In
the United States, dental services are increasingly being paid for by third
parties. Third party payors paid approximately $15.2 billion in 1990 and $24.0
billion in 1995 for dental services in the United States, which represented
approximately 48.1% and 52.4%, respectively, of total dental products and
services expenditures in those years. Additionally, the National Institute of
Dental Research estimates that Americans saved nearly $100 billion in dental
expenditures during the 1980s because of dentistry's emphasis on preventive oral
health. Since prophylaxis procedures and treatments are generally less expensive
than treatment of dental diseases, an increasing number of consumers and third
party payors have recognized the cost effectiveness of preventive dentistry.
 
     Publicity concerning exposure to and possible transmission of communicable
diseases, including HIV and hepatitis, through contact with blood, saliva and
other bodily fluids in the dental office has led to the establishment of
regulations and guidelines by OSHA, the Center for Disease Control and
Prevention, the American Dental Association and state regulatory authorities.
The Company believes that the increasing emphasis on preventive dentistry and
infection control will result in increased demand for the Company's products.
 
                                       23
<PAGE>   25
 
     Favorable Demographic Trends. The Company believes there will be growth in
the demand for preventive dentistry as a result of people retaining their
natural teeth longer and thus continuing their need for dental services.
Additionally, the Company believes demand will continue for preventive dentistry
as parents, who have grown up benefiting from preventive dentistry, obtain such
services for their children. Finally, continued growth in the United States
population should continue to drive demand for preventive dentistry and
infection control products.
 
     Growth in International Markets. The Company believes that international
demand for preventive dentistry and infection control products varies according
to the degree of general awareness of the benefits of preventive dentistry, as
well as social, economic and technological development. North America, the
Scandinavian countries, Australia and New Zealand provide the most advanced
dental procedures and products and have the highest levels of expenditures for
preventive dental care. Outside of these areas, preventive dentistry has
generally not been emphasized or covered under government or private health
insurance. However, there has been an increasing awareness worldwide of the
importance and cost effectiveness of preventive dentistry, which the Company
believes will result in growth in international markets such as Europe, South
America, Central America and the Pacific Rim.
 
BUSINESS STRATEGY
 
     The Company's objective is to profitably establish the number one or number
two market share position in each of the market segments in which it competes.
In order to achieve this objective, the Company's business strategy comprises
the following elements: (i) expand its market position in preventive and
infection control products by leveraging its strong brand names; (ii) enhance
its strong manufacturing capabilities; and (iii) emphasize recurring revenue
streams and cash flows from single-use products.
 
     Leverage Branded Products. The Company believes that its name recognition
and reputation among distributors and dental professionals for quality products,
depth of product offerings and responsiveness to customer needs provide it with
opportunities to increase market share for its branded and recently acquired
product lines. Specifically, the Company plans to leverage its leadership
position in Prophy Products, where the Young and Denticator brands are well
established, in order to increase market penetration of its complementary
preventive and infection control products. The Company intends to accomplish
this by (i) packaging complementary products with its well-known metal and
disposable prophy angles; (ii) frequently providing sample products to
distributors and dental professionals; (iii) increasing distributor education
and training with regard to the Company's complete product line; and (iv)
selectively increasing marketing efforts to dental professionals. The Company
believes that its name recognition and strong relationships with its key
distributors provide a significant opportunity to leverage the Company's brand
names across a broader set of products.
 
     Enhance Strong Manufacturing Capabilities. The Company strives to be the
low cost producer in each market segment in which it competes, while also
maintaining its reputation for high quality, innovative and reliable products.
Since 1990, the Company has and continues to operate under a continuous
improvement initiative that empowers all of its employees to improve the quality
and efficiency of its manufacturing, operations, marketing and administrative
functions. In addition, the Company employs several proprietary molding,
vulcanizing and other manufacturing processes that allow for highly efficient
and automated manufacturing. The Company's manufacturing strengths, including
its continuous improvement program and proprietary processes, are key factors in
its ability to generate a high gross margin, which, in 1996, was 55.6% of pro
forma net sales. The Company is currently implementing its continuous
improvement strategies with Lorvic and Denticator, and will do so with future
acquisitions when appropriate.
 
     Emphasize Recurring Revenue Streams. The Company is focused on continuing
to develop and emphasize products that generate recurring streams of revenue.
These products include disposable prophy angles, consumables, such as pastes and
fluorides and disposables, such as prophy cups and brushes that are required for
the Company's metal prophy angles to work properly and which also work on its
competitors' metal prophy angles. Single-use products represented 92.9% of the
Company's 1996 pro forma net sales.
 
                                       24
<PAGE>   26
 
GROWTH STRATEGY
 
     The Company competes effectively in the rapidly changing professional
dental product industry and capitalizes on its strong name recognition and
responsiveness to customer needs. The Company's net sales have increased at a
compound annual growth rate of 19.3% over the last 10 years and 21.4% since
1992. These increases have been achieved through strong internal growth
complemented recently by two recent acquisitions.
 
     Pursue Strategic Acquisitions. The Company aggressively pursues
acquisitions of complementary businesses, product lines and key technologies. In
1995, the Company's product lines expanded significantly with the acquisition of
Lorvic, a manufacturer of aspiration, infection control and preventive dental
products including preventive pastes, fluorides and fluoride applicators and
plaque disclosure products. Additionally, in 1996, the acquisition of Denticator
expanded the Company's line of Prophy Products. In general, the professional
dental products manufacturing industry is fragmented and comprised of small and
medium size companies. Limited manufacturing and distribution resources,
increasing regulatory requirements and pricing pressures resulting from the
consolidation of distributors and dental service providers make it increasingly
difficult for these companies to operate effectively on a stand-alone basis,
thus presenting a significant opportunity for the Company to make acquisitions.
In addition, the Company intends to explore selective strategic dental
acquisition opportunities outside of the preventive dentistry and infection
control markets.
 
     Develop New Products. An important element of the Company's growth strategy
is to develop high value-added products for specific professional dental
products markets based on its existing core capabilities and technologies. New
products or product extensions introduced by Young Dental since 1990 represented
42.5% of the Company's pro forma net sales in 1996. In the early 1990's,
responding to concerns of cross-contamination resulting from multiple-use
products, Young Dental developed a number of plastic disposable prophy angles
designed for single-use and broadened its existing line of sealed metal angles
designed to prevent the intake of blood, saliva and other matter. Young Dental
introduced the industry's first contra disposable prophy angle in early 1995 and
eight other new products or product extensions from 1993 through 1996. The
Company introduced six new products through August 31, 1997, and plans to
introduce 14 new products or extensions in the remainder of 1997 and 1998.
 
     Expand Internationally. The Company intends to continue to expand its
presence in several international markets, including Europe, South America,
Central America and the Pacific Rim. Outside North America, Scandinavia,
Australia and New Zealand, the benefits of preventive dentistry have not been
widely emphasized or covered under government or private health insurance.
However, awareness of the importance and cost effectiveness of preventive
dentistry is generally increasing worldwide. The Company plans to continue to
foster its relationships with international distributors and to closely monitor
changing trends in preventive dentistry throughout the world. The Company will
not undertake broad expansionary activities until significant change in the
recognition of the benefits of preventive dentistry, the reimbursement policy of
third party payors with respect to preventive dentistry procedures or increased
customer demand occurs, at which time the Company plans to be in a strategic
position to capitalize quickly on these market opportunities.
 
PRODUCTS
 
     The Company primarily markets disposable and metal prophy angles, cups and
brushes, complementary preventive products, including pastes, fluorides and
fluoride applicators, as well as aspiration and infection control products. In
1996, 76.9% of the Company's pro forma net sales were derived from the sale of
Prophy Products.
 
     Prophy Products. The Company manufactures and sells the broadest line of
Prophy Products in the domestic professional dental products market. The Company
is able to achieve its substantial share of the Prophy Product market by
providing Prophy Products at both premium and popular prices. The Company
generally prices its Young branded Prophy Products at premium levels and its
Denticator branded Prophy Products at popular price levels. The Company's broad
range of Prophy Products enables it to be a single-source supplier to its
distributors.
 
                                       25
<PAGE>   27
 
     The Company's Prophy Products include several configurations of sealed
metal autoclavable prophy angles and several disposable plastic prophy angles
designed for single-use. Prophy Products consist of two components: an angle
which is attached to and extends from a standard, low-speed dental handpiece and
a rubber cup or brush which is attached to the angle and performs the cleaning
function. During the prophylaxis process, the cup or brush is filled with
abrasive paste, which is applied to the teeth as the prophy cup rotates. The
dental professional polishes both the visible portion of the tooth and the
subgingival portion (below the gum line). The prophy angle may be a disposable
or a reusable instrument; prophy cups and brushes are sold as single-use items.
Disposable prophy angles are sold as assembled units with a cup or brush already
attached. The Company produces and markets a number of different disposable
prophy angles, including the traditional, contra and Universal Disposable Angle.
Virtually all of the Company's metal prophy angles are sealed against
penetration of matter from patients' mouths (thus reducing the risk of
cross-contamination and damage to the prophy angle) and are designed for ease of
maintenance. Because such metal prophy angles function correctly only when used
with the Company's cups and brushes, most dentists who purchase the Company's
metal prophy angles also purchase the Company's cups and brushes.
 
     Other Preventive Products. The Company's other preventive products include
38 polishing pastes and powders, which are abrasive agents used for cleaning and
polishing teeth; 12 fluorides used in dental offices and at home to reduce
cavities and tooth sensitivity; six applicators used by dental professionals to
apply fluoride to patients' teeth; and four plaque disclosants, which are
liquids or tablets that identify the presence of plaque when applied to tooth
surfaces. The Company markets certain of its pastes and fluoride products in
single-use containers, the demand for which has grown in response to infection
control concerns.
 
     Infection Control Products. The Company's line of infection control
products includes products such as indicator tape and tabs used to verify the
effectiveness of a sterilizer; Nyclave wrap used to wrap instruments during
sterilization so that sterility is maintained until use; barrier products used
to wrap operatory knobs, handles and other devices that cannot be sterilized;
and surgical milk and instrument care products used to inhibit corrosion, remove
rust and lubricate hinged instruments in connection with the autoclave process.
Autoclaving is the sterilization of instruments and equipment through the use of
steam.
 
     Assisting and Other Products. The Company's assisting and other products
include disposable aspiration products used to remove blood, saliva and other
matter during dental procedures; cotton roll substitutes used to control saliva
and moisture during dental procedures; matrix bands used for tooth restorations;
rubber dam frames used to isolate teeth during dental procedures; and etching
gels and bonding prep used to condition tooth surfaces for bonding.
 
     Private Label and OEM Products. In addition to branded products, the
Company designs, develops and produces a limited number of proprietary private
label and OEM products under contracts with dental distributors and other
professional dental product manufacturers where the Company is able to use its
expertise and excess manufacturing capacity.

MARKETING AND DISTRIBUTION
 
     The Company markets its full line of products to dental professionals
worldwide using a network of medical and dental product distributors. The
Company actively supports its distributor relationships with Company sales
personnel in the United States, independent sales representatives in Canada and
exclusive sales representatives in 13 countries outside of North America. The
Company also uses non-exclusive distributors to service markets in 40 other
countries. All major distributors of dental products in North America sell the
Company's products, including Patterson, Schein, Sullivan and Meer. The
Company's product development, manufacturing and marketing capabilities and its
relationships with distributors allow the Company to provide a broad range of
high quality, innovative and reliable products to dental professionals.
Additionally, these capabilities and relationships enable the Company to quickly
and efficiently offer new products or product extensions to its existing
customer base and new markets. In addition to marketing through distributors in
the United States, the Company sells products directly to dental and dental
hygiene schools, Veterans Administration healthcare facilities and United States
military bases.
 
     Company's products are marketed by five employees in the United States and
by three independent sales representatives in Canada. The Company also supports
its marketing activities to smaller distributors through use of the Company's
inside sales personnel. Until July 1997, the Company used 19 independent non-
exclusive sales representatives and two Company employees for its marketing and
sales efforts in the United States. In an effort to more efficiently market its
products, the Company decided to switch from independent sales representatives
to Company employees who exclusively focus on selling the Company's products.
 
     The Company expends considerable effort educating its distributors about
the quality, reliability and features of its products. The Company also
advertises its products through industry publications and direct mail. To
supplement its other marketing efforts, the Company provides product samples to
dental
 
                                       27
<PAGE>   29
 
professionals and exhibits its products at industry trade shows. In addition,
the Company seeks to stimulate interest in its products by providing information
and marketing materials to influential lecturers and prominent experts and
consultants in the dental industry.
 
PRODUCT DEVELOPMENT
 
     The Company's engineers and chemists are focused on developing innovative
professional dental products and are actively involved in improving the
Company's manufacturing processes. Frequently, these products are designed and
developed in response to needs articulated to the Company by dental
professionals. For example, the Company designed the contra disposable prophy
angle to improve the ease with which dental professionals can reach and clean
patients' teeth. The Company believes that the contra disposable prophy angle
reduces the risk of carpal tunnel syndrome by reducing the flexion of dental
hygienists' wrists during prophy procedures. Additionally, many of the new
products or product improvements developed by the Company are patented. The
Company currently has 28 patents and 14 patent applications pending.
 
     All of Young Dental's disposable prophy angles have been developed since
1990. In June 1997, Young Dental introduced its new Junior Cup, a short
prophylaxis cup designed to reach surfaces in small mouths that are difficult to
reach with the Company's conventionally sized cups. In June 1997, Denticator
introduced the Universal Disposable Angle which was designed to compete with a
number of popular priced branded and private label disposable prophy angles
manufactured by the Company's competitors. In 1997, the Company plans to
introduce two metal prophy angles, including an improved version designed for
smoother and more durable operation and a Denticator branded version designed to
compete with popular priced metal prophy angles.
 
     In addition to its Prophy Product development efforts, the Company actively
seeks to introduce new and innovative products in other segments of the
professional dental product market. In the remainder of 1997 and 1998, the
Company intends to introduce a newly formulated prophy paste and a new line of
fluorides and fluoride applicators.
 
MANUFACTURING AND SUPPLY
 
     The Company manufactures virtually all of its products. The consolidation
of the Company's two St. Louis facilities into the expanded Earth City facility,
which was substantially completed in December 1996, provides the Company with
sufficient manufacturing capacity for anticipated growth in the foreseeable
future. The Company contracts for the assembly of approximately 72% of its
disposable prophy angles in Mexico due to its cost effectiveness.
 
     Prophy and Other Products. The Company has developed a number of
proprietary manufacturing processes and has designed specialized automated
equipment which allow it to produce quality products rapidly and efficiently.
The Company believes its equipment and proprietary processes provide it with a
competitive advantage. The Company uses a variety of state-of-the-art computer
numerically controlled machining centers, injection molding machines and robotic
assembly machines and continues to invest in new and more efficient equipment
and production lines. The primary processes involved in manufacturing the
Company's products consist of precision metal turning and milling, rubber
molding, plastic injection molding, component parts assembling and finished
goods packaging.
 
     Denticator converted from a repackaging operation to an injection molding
and manufacturing operation in April 1997. Since Denticator principally
manufactures disposable prophy angles, the primary processes involved in its
manufacturing process include plastic injection molding and finished goods
packaging.
 
     Pastes, Liquids and Gels. Lorvic blends and mixes all of its pastes,
liquids and gels at the Earth City facility. The Company owns equipment used to
form and dye-cut expanded polyethylene foam and to dye-cut extruded plastic into
finished products and equipment used to package its products in a variety of
container sizes, including prophy paste in unit-dose containers.
 
     Total Quality Management. The Company has implemented, where appropriate,
manufacturing techniques to increase product quality and minimize operating
costs. Products are statistically monitored during the manufacturing process in
order to maintain a high level of quality and reduce scrap. Young Dental also
 
                                       28
<PAGE>   30
 
undertakes extensive cross-training of its employees, allowing the employees to
understand the entire manufacturing process and encouraging them to introduce
manufacturing improvements. The Company has, where appropriate, implemented
Young Dental's manufacturing techniques into Lorvic's operations and is in the
process of implementing these techniques into Denticator's operations. The
Company believes these techniques will further increase Denticator's
manufacturing efficiencies, thereby improving its gross margin.
 
     Supply. The Company purchases a wide variety of raw materials, including
bar steel, brass, rubber and plastic resins, from numerous suppliers. The
majority of the Company's purchases are commodities readily available at
competitive prices. The Company has two sources of supply for the rubber
formulation used to produce its prophy cups. The rubber formulations were
developed independently and are owned by each of the suppliers. The Company also
purchases certain of its products from other manufacturers for resale.
 
COMPETITION
 
     The Company competes with manufacturers of both branded and private label
dental products in each of the markets it serves. According to Strategic Dental
Marketing, Inc., an independent market research firm, Young Dental has the
largest domestic market share of distributor sales in Prophy Products.
 
     Dental professionals place major importance on the proven reliability of
the Company's products and are generally not price-sensitive. The Company
believes that Young Dental and Lorvic compete on the basis of the quality and
reliability of their products as well as their reputations. As a result, Young
Dental and Lorvic typically charge premium prices for their products. By
contrast, Denticator's products are targeted to more price-sensitive dental
service providers.
 
     The markets for the Company's products are highly competitive. The Company
believes that the principal competitive factors in all of its markets are
product features, reliability, name recognition, established distribution
network, customer service and, to a lesser extent, price. The relative speed
with which the Company can develop, complete testing, obtain regulatory approval
and sell commercial quantities of new products is also an important competitive
factor. Some of the Company's competitors have greater financial, research,
manufacturing and marketing resources than the Company and include DENTSPLY
International, Inc., Oral-B Laboratories, a subsidiary of The Gillette Company,
and Allegheny Teledyne Incorporated.

EMPLOYEES
 
     As of June 30, 1997, the Company employed approximately 166 people, none of
whom were covered by collective bargaining agreements. The Company believes that
its relations with its employees are good.
 
GOVERNMENT REGULATIONS
 
     The development, manufacture and marketing of the Company's products are
subject to extensive and rigorous regulation by the FDA and by other
governmental agencies and relevant foreign agencies. Certain of the Company's
current products are sold in the United States under 510(k) clearances and
exemptions from FDA approval requirements. The FDA also regulates the uses for
which products may be promoted and the claims that may be made in promotional
materials.
 
                                       29
<PAGE>   31
 
     The Company's facilities, manufacturing operations and customers and
suppliers are subject to FDA Quality System Requirements and Good Manufacturing
Practices and extensive recordkeeping and reporting requirements for sales in
the United States. The Company's manufacturing facilities, and the facilities it
contracts with in Mexico to assemble disposable prophy angles, are subject to
periodic inspections by United States federal agencies.
 
LEGAL PROCEEDINGS
 
     On May 30, 1997, two former employees of Young Dental and a corporation
formed by them (the "Adverse Parties") filed a Petition against Young Dental in
the Circuit Court for the City of St. Louis, Missouri (the "Current Action").
The Current Action results from an action brought in 1993 by Young Dental
against the Adverse Parties in the Federal District Court for the Eastern
District of Missouri (the "Prior Action"), alleging, among other things, patent
infringement and misappropriation of trade secrets. The Prior Action was
resolved in favor of the Adverse Parties. In the Current Action, consisting of
three counts alleging malicious prosecution and three counts alleging abuse of
process related to the Prior Action, the Adverse Parties seek actual damages in
unspecified amounts in excess of $25,000 and, in a separate count, seek punitive
damages. While the Current Action is in its very early stages, the Company
believes it has adequate defenses to each of plaintiffs' claims and intends to
defend the Current Action vigorously.
 
     The IRS examined Lorvic's federal income tax returns for the years ended
March 31, 1992 through 1995 and proposed deficiencies in federal income taxes
for those years in an aggregate amount of $766,000 due to classification of
certain intangible assets. Lorvic has filed two petitions with the United States
Tax Court contesting these proposed deficiencies. The first of these petitions,
which relates to the years ended March 31, 1992 and 1993, is scheduled for trial
in October 1997. In accordance with the stock purchase agreement pursuant to
which the Company acquired Lorvic in May 1995, the previous stockholders of
Lorvic are responsible for the settlement of this matter to the extent of
$700,000 held in an escrow fund, together with earnings thereon, plus an
additional $200,000 to cover any interest and penalties related to such matters.
While there can be no such assurance, the Company believes the escrowed amounts
will be sufficient to satisfy these deficiencies in full for all affected years
if required. See "Certain Transactions."
 
     The Company is not involved in any other legal proceedings but, from time
to time, does become involved in legal proceedings in the ordinary course of its
business.

years after expiration or termination of the employment agreement.
 
STOCK OPTION PLAN
 
     The Company has adopted the 1997 Stock Option Plan (the "Option Plan") to
be effective as of the closing of the Offering. A total of 350,000 shares of
Common Stock are reserved for issuance under the Option Plan. The compensation
committee of the Board of Directors (the "Committee") will administer the Option
Plan. Participants in the Option Plan will be those employees of the Company or
its subsidiaries as the Committee may select from time to time. No options have
been granted under the Option Plan as of the date of this Prospectus.
 
     Options to be granted may be incentive stock options ("ISOs") meeting the
requirements of Section 422 of the Internal Revenue Code or may be options other
than ISOs (non-qualified options or "NQSOs"). The exercise price of an ISO or
NQSO will be equal to the fair market value (as defined in the Option Plan) per
share of the Common Stock on the date of the grant. The aggregate fair market
value of the Common Stock on the date of grant for which any participant may be
granted ISOs first exercisable in any year may not exceed $100,000. The exercise
price is required to be paid in full at the time of exercise in cash or its
equivalent or, upon approval of the Committee, in shares of Common Stock. ISOs
and NQSOs granted under the Option Plan will be exercisable for a term of not
more than ten years as determined by the Committee and, unless otherwise
provided in the stock option agreement relating to a particular option, will
terminate upon the participant's termination of employment to the extent not
then exercisable. Options that have become exercisable on or prior to the date
of termination of employment terminate at the earlier of: (i) the expiration
date of the option; or (ii) where such termination occurs as a result of death
or disability, one year after termination of employment; or (iii) where such
termination occurs other than as a result of death or disability, immediately
upon termination of employment. Options granted under the Option Plan are not
transferable by the grantee other than by will or the laws of descent and
distribution. All other terms, including the time or times at which an option
becomes exercisable, are determined by the Committee in its discretion.
 
OTHER BENEFIT PLANS
 
     The Company has a nonqualified bonus plan under which 5% of base
compensation is annually paid to full-time employees in Missouri and Texas who
are at least 25 years of age and have at least three years of service with the
Company. The Company also has a nonqualified profit sharing plan for its
full-time employees in Missouri and Texas under which contributions are based on
the overall profitability of the Company, excluding Denticator.

                              CERTAIN TRANSACTIONS
 
     Solutions in 3D, Inc. ("3D"), a manufacturer of plastic resin prototypes,
leases space from the Company at its premises in Earth City at a rental of $750
per month. George Richmond and Michael Eggleston own 52.5% and 15.0%,
respectively, of the outstanding common stock of 3D. The Company has, from time
to time, loaned money to 3D which, as of June 30, 1997, aggregated $48,000 with
interest payable monthly at the prime rate of a local bank; the note evidencing
the loan has no maturity date and is unsecured. The highest principal balance of
the loan at any time was $90,000. 3D's business is primarily with unrelated
third parties. In 1994, 1995, 1996 and the six months ending June 30, 1997,
respectively, the Company paid an aggregate of $9,000, $14,000, $10,000 and
$6,000 to 3D for plastic resin prototyping services provided to the Company.
 
                                       34
<PAGE>   36
 
Following completion of the Offering, 3D will continue to lease space from the
Company and the Company may continue to loan 3D money from time to time and
purchase services from 3D. The Company has adopted a policy that all
transactions between the Company and any affiliated party will be approved by a
majority of all members of the Company's Board of Directors and by a majority of
the independent and disinterested Directors and will continue to be on terms no
less favorable to the Company than terms the Company believes would be available
from unaffiliated third parties.
 
     George Richmond is a 40% minority stockholder and former officer and
director of Earth City Technologies ("Technologies"), a company located in
Fenton, Missouri. Technologies repairs damaged scalers for the Company returned
by its customers and sells scaler parts. Total amounts paid to Technologies for
repairs in 1994, 1995, 1996 and the first six months of 1997, respectively, were
$27,000, $38,000, $41,000 and $7,000. Prior to February 1997, the date the
distribution arrangements were terminated, Technologies distributed Young Dental
products in the St. Louis metropolitan area, at the same price and on the same
terms as the Company's other distributors. Total amounts billed to Technologies
in 1994, 1995, 1996 and the six months ending June 30, 1997, respectively, were
$47,000, $15,000, $34,000 and $58,000. Mr. Richmond is currently not an officer,
director or employee of Technologies and plays no role in its management. The
Company believes that arrangements with Technologies are on terms to the Company
as favorable as could be obtained from unaffiliated third parties. Following
completion of the Offering, Technologies will continue to provide repair
services to the Company.
 
     The Company, George Richmond and certain employee stockholders of the
Company are parties to agreements (the "Stock Plan") pursuant to which Mr.
Richmond sold on two separate occasions an aggregate of 242,512 shares of Common
Stock at appraised values to employees under an arrangement giving the employees
the right and, upon termination of employment, the obligation to sell their
Common Stock at an appraised value either to Mr. Richmond or to the Company. The
last such sale by Mr. Richmond took place in 1993. In addition, the Company is a
party to agreements (the "Buy-Sell Agreement") with five trusts for the benefit
of children of George Richmond, including a trust for the benefit of Richard
Richmond, pursuant to which the non-selling trusts and the Company have rights
of first refusal to purchase Common Stock held by the trusts desiring to sell
their Common Stock. Each of the Stock Plans and the Buy-Sell Agreements will
terminate upon completion of the Offering.
 
     Mr. Richmond has pledged 2,391,285 shares of Common Stock as additional
collateral for the Company's borrowings, which pledge will be released upon
repayment of such borrowings under the Credit Agreement.
 
     Jose Mendoza, five other Denticator employees and Michael Eggleston
organized Hot Plastics Technologies, Inc. ("HPT"), which performed injection
molding for Denticator between January and April, 1997. Mr. Mendoza and Mr.
Eggleston, respectively, held 70% and 5% of the equity of HPT. In April 1997,
Denticator purchased the assets of HPT; the sole consideration paid by
Denticator for the acquisition was the assumption of HPT's liabilities, which
aggregated $606,000 and included a note payable to Mr. Mendoza of $104,000. The
terms of the acquisition were negotiated for Denticator by the Chief Executive
Officer of the Company. Denticator paid HPT an aggregate of $213,000 for
injection molding services performed prior to the acquisition.
 
     In February 1994, Young Dental repaid notes issued to the stockholders of
Young Dental representing all undistributed income of Young Dental during the
period it was an S Corporation.
 
                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     Upon the closing of this Offering, the authorized capital stock of the
Company will consist of 25,000,000 shares of Common Stock, par value $.01 per
share, of which 6,410,296 shares will be outstanding. As of the date of this
Prospectus, the Company had a total of 13 holders of shares of Common Stock.

COMMON STOCK
 
     Holders of Common Stock are entitled to receive ratably such dividends as
may be declared by the Board of Directors out of legally available funds. See
"Dividend Policy." In the event of a liquidation, dissolution or winding up of
the Company, holders of the Common Stock are entitled to share ratably in all
assets remaining after payment of liabilities. Holders of Common Stock have no
preemptive rights and no right to convert their Common Stock into any other
securities. There are no redemption or sinking fund provisions applicable to the
Common Stock. All outstanding shares of Common Stock are, and all shares of
Common Stock to be outstanding upon completion of this Offering will be, fully
paid and nonassessable. The holders of Common Stock are entitled to one vote for
each share held of record on all matters submitted to a vote of stockholders.
The holders of Common Stock do not have cumulative voting rights in the election
of directors.
 
TRANSFER AGENT AND REGISTER
 
     UMB Bank, N.A. is the transfer agent and registrar for the Common Stock.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have 6,410,296 shares of
Common Stock outstanding. Of these shares, 2,000,000 shares of Common Stock sold
in the Offering will be freely tradeable without restrictions under the Act,
except for shares purchased by an "affiliate" of the Company which will be
subject to the resale limitations (but not holding period requirements) of Rule
144 thereunder. The remaining 4,410,296 shares of Common Stock were issued and
sold by the Company in private transactions in reliance upon various exemptions
under the Act. Substantially all of such shares will be eligible for public sale
following the Offering subject to compliance with the volume and manner of sale
limitations of Rule 144. In general, under Rule 144 a person (or persons whose
shares are aggregated) including a person who may be deemed an "affiliate" of
the Company, who has beneficially owned his shares for at least one year is
entitled to sell within any three-month period that number of shares which does
not exceed the greater of 1% of the outstanding shares of Common Stock or the
average weekly trading volume during the four calendar weeks preceding each such
sale. Sales under Rule 144 also are subject to certain manner of sale
provisions, notice requirements and the availability of current public
information about the Company. A person (or persons whose shares are aggregated)
who is not and has not been deemed an "affiliate" of the Company for at least
three months and who has beneficially owned his shares for at least two years is
entitled to sell such shares under Rule 144(k) without regard to the limitations
discussed above. All of the officers, Directors and stockholders of the Company
and the Company have agreed not to sell any of their shares of Common Stock to
the public for a period of 180 days after the date of the Prospectus without the
prior written consent of Robert W. Baird & Co. Incorporated.
 
     The preceding description does not give effect to the shares of Common
Stock which may be offered and sold pursuant to the Option Plan. See "Management
- -- Stock Option Plan". The Company intends to file a registration statement on
Form S-8 under the Act not earlier than 90 days after the date of this
Prospectus to register the shares of Common Stock issuable under the Option
Plan, which shares, after registration, will be immediately available for sale
in the public market, subject to the volume and other limitations of Rule 144
for shares held by affiliates and the terms of the Option Plan.
 
     Since there has been no public market for the Common Stock prior to the
Offering, no predictions can be made as to the effect, if any, that market sales
or the availability of shares for sale will have on the market price prevailing
from time to time. Nevertheless, sales of substantial amounts of the Common
Stock, or the perception that such sales could occur, could adversely affect the
prevailing market price of the Common Stock.

     The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
their counsel and to various other conditions. The Underwriters are obligated to
purchase all the shares of Common Stock offered hereby, excluding shares covered
by the over-allotment option granted to the Underwriters, if any are purchased.
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the Common Stock to the public at the initial public offering
price set forth on the cover page of this Prospectus and may offer the Common
Stock to certain dealers at such price, less a concession of not in excess of
$       per share and that the Underwriters and such dealers may reallow a
concession of not in excess of $       per share to certain brokers or other
dealers. The public offering price and concessions and reallowances to dealers
may be changed by the Representatives after the commencement of the Offering.
 
     The Company has granted to the Underwriters an option, exercisable within
30 days after the date of the Offering, to purchase up to an additional 300,000
shares of Common Stock to cover over-allotments, at the same price per share to
be paid by the Underwriters for the other shares offered hereby. If the
Underwriters purchase such additional shares pursuant to this option, each of
the Underwriters will be committed to purchase such additional shares in
approximately the same proportion as set forth in the above table. The
Underwriters may purchase such shares only to cover over-allotments, if any, in
connection with the Offering.
 
     The Underwriting Agreement provides that each of the Company and the
Underwriters have agreed to indemnify, or to contribute to payments made by,
each other with respect to certain civil liabilities, including certain civil
liabilities under the Act.
 
     Prior to the Offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock will be determined
by negotiation among the Company and the Representatives. The factors considered
in determining the initial public offering price include the history of and
prospects for the industry in which the Company operates, past and present
operations, revenues and earnings of the Company and the trend of such earnings,
the prospects for such earnings, the Company's capital requirements, percentage
of ownership to be held by investors following the Offering, the general
condition of the securities markets at the time of the Offering and the demand
for similar securities of reasonably comparable companies.
 
     The Underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act of 1934 (the "Exchange Act"). Over-allotment
involves syndicate sales in excess of the offering size, which creates a
syndicate short position. Stabilizing transactions permit bids to purchase the
underlying security so long as the stabilizing bids do not exceed a specified
maximum. Syndicate covering transactions involve purchases of the securities in
the open market after the distribution has been completed in order to cover
syndicate short positions. Penalty bids permit the Underwriters to reclaim a
selling concession from a syndicate member when the securities originally sold
by such syndicate member are purchased in a syndicate covering transaction to
cover syndicate short positions. Such stabilizing transactions, syndicate
covering transactions and penalty bids may cause the price of the securities to
be higher than it would otherwise be in the absence of such transactions.

     The Representatives have informed the Company that the Underwriters do not
intend to make sales to any accounts over which they exercise discretionary
authority.
 
     The Company and its officers, Directors and stockholders have agreed not to
sell, contract to sell or otherwise dispose of any shares of Common Stock for a
period of 180 days after the date of the Prospectus without the prior written
consent of Robert W. Baird & Co. Incorporated.

Underwriting Agreement and does not purport to be a complete statement of its
terms and conditions. A copy of the Underwriting Agreement is on file with the
Commission as an exhibit to the Registration Statement of which this Prospectus
forms a part. See "Additional Information."

statements is effected, we expect to be in a position to render the following
audit report.
 
ARTHUR ANDERSEN LLP
 
                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Young Innovations, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Young
Innovations, Inc. (a Missouri corporation) and subsidiaries as of December 31,
1996 and 1995, and the related consolidated statements of income, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our 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.

            (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AND SHARE DATA)
 
1. DESCRIPTION OF BUSINESS:
 
     Young Innovations, Inc. and its subsidiaries (the Company) designs,
manufactures and markets single-use supplies, autoclavable instruments and other
products used by dental professionals, primarily in preventive dentistry and
infection control. The Company manufactures and markets metal and disposable
prophy angles, cups and brushes that are integral components used in the
cleaning and polishing of teeth by dental professionals. The Company's
manufacturing facilities are located in Missouri, California and Texas. The
Company markets its products to dental professionals worldwide through a network
of medical and dental product distributors. Export sales were less than 10% of
total net sales for 1994, 1995 and 1996.
 
     The accompanying consolidated balance sheet as of June 30, 1997, and
related consolidated statements of income and cash flows for the six months
ended June 30, 1996 and 1997, and consolidated statement of stockholders' equity
for the six months ended June 30, 1997, and related disclosures, are unaudited.
In the opinion of management, these statements have been prepared on the same
basis as the audited consolidated financial statements and include all
adjustments necessary (consisting only of normal, recurring adjustments) for the
fair presentation of financial position, results of operations and cash flows.
The results of operations for the six months ended June 30, 1997, are not
necessarily indicative of the results which may be expected for the year ending
December 31, 1997.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of Young
Innovations, Inc., formed in July 1995, and its direct and indirect wholly owned
subsidiaries, Young Dental Manufacturing Company (Young Dental), Lorvic
Holdings, Inc., The Lorvic Corporation, Young Dental International, Inc. and
Denticator International, Inc. (Denticator). Lorvic Holdings, Inc. and The
Lorvic Corporation (Lorvic) are included since their acquisition on May 5, 1995.
Young Dental International, Inc., a Foreign Sales Corporation, is included since
its inception on February 1, 1996, and Denticator is included since its
acquisition on July 22, 1996. All significant intercompany accounts and
transactions are eliminated in consolidation. The Company operates in one
business segment.
 
     The preparation of these financial statements required the use of certain
estimates by management in determining the Company's assets, liabilities,
revenues and expenses. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents include all highly liquid investments with an
initial maturity of three months or less.
 
INVENTORIES
 
     Inventories are stated at the lower of cost (which includes material, labor
and manufacturing overhead) or market. Cost is determined by the first-in,
first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment are stated at cost. Expenditures for repairs
and maintenance are charged to expense as incurred, and additions and
improvements that significantly extend the lives of assets are capitalized. Upon
disposition, cost and accumulated depreciation are eliminated from the related
accounts and

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
any gain or loss is reflected in other income or expense. The Company provides
depreciation using the straight-line method over the estimated useful lives of
the assets ranging from five to thirty-nine years. Effective October 1, 1995,
the Company changed the estimated useful lives of certain equipment that had the
effect of reducing depreciation expense by approximately $132 for 1995.
 
MARKETABLE SECURITIES
 
     Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." Under SFAS No. 115, the Company's marketable debt
securities consisting of municipal bonds, are classified as "available for sale"
and accordingly, are reflected at fair value with the corresponding impact
included as a component of stockholders' equity designated "unrealized gain on
marketable securities, net of tax." As of December 31, 1995 and 1996, there were
no unrealized losses on any individual security. As of December 31, 1996, the
marketable securities have contractual maturities varying from 2009 to 2019.
 
OTHER ASSETS
 
     Other assets include costs related to patents issued to the Company and
pending patent applications. Capitalized patent costs are amortized on a
straight-line basis over the estimated useful lives of the patents, generally 17
years.
 
INTANGIBLE ASSETS
 
     Intangible assets are stated at cost less accumulated amortization.
Amortization is determined using the straight-line method over 40 years.
 
LONG-LIVED ASSETS
 
     If facts and circumstances suggest that a long-lived asset may be impaired,
the carrying value is reviewed. If this review indicates that the carrying value
of the asset will not be recovered, as determined based on projected
undiscounted cash flows related to the asset over its remaining life, the
carrying value of the asset is reduced to its estimated fair value.
 
RESEARCH AND DEVELOPMENT COSTS
 
     Research and development costs are expensed when incurred and totaled $159
for 1994, $352 for 1995 and $597 for 1996.
 
REVENUE RECOGNITION
 
     Revenue from the sale of products is recorded at the time of passage of
title, generally when the products are shipped.
 
OTHER EXPENSE (INCOME)
 
     Other expense (income) includes gain and loss on disposition of fixed
assets, sale of scrap, and other miscellaneous income and expense items, all of
which are not directly related to the Company's primary business. In 1995 and
1996, net gains on the sale of equipment and other fixed assets totaled $242 and
$219, respectively. Other 1996 expenses include approximately $322 of deferred
offering costs expensed as a result of the Company withdrawing its registration
statement in 1996 with respect to its efforts to go public in 1995.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
INCOME TAXES
 
     The Company has accounted for income taxes under SFAS No. 109, an asset and
liability approach to accounting and reporting for income taxes. Deferred income
taxes are provided for temporary differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities.
 
SUPPLEMENTAL CASH FLOW INFORMATION
 
     Cash flows from operating activities include $1,036, $1,851 and $1,898 for
the payment of federal and state income taxes and $189, $741 and $931 for the
payment of interest during 1994, 1995 and 1996, respectively. Interest paid to
stockholders was $147 during 1994.
 
3. ACQUISITIONS:
 
     On July 22, 1996, the Company acquired the assets and liabilities of
Denticator from Bio Dental Technologies Corp. (Bio Dental) and an individual.
The purchase price was financed principally through bank debt. The acquisition
of Denticator was accounted for as a purchase transaction. The purchase price
was allocated based upon estimates of fair value. Differences between the
amounts included herein, if any, and final allocations of purchase price are not
expected to have a material effect on the Company's financial statements.
 
     The excess of purchase price over the fair value of net assets acquired was
$7,575 and is being amortized over 40 years. The purchase price allocation is as
follows:

4. CONCENTRATIONS OF CUSTOMERS AND SUPPLIERS:
 
     The Company generates trade accounts receivable in the normal course of
business. The Company grants credit to distributors throughout the world and
generally does not require collateral to secure the accounts receivable. The
Company's credit risk is concentrated among three distributors accounting for
41% and 45% of accounts receivable as of December 31, 1995 and 1996,
respectively.
 
     The Company has two suppliers for the rubber used to produce its prophy
cups. The Company relies on proprietary rubber formulations that were
independently developed and are owned by these suppliers. If the Company is no
longer able to obtain its rubber or the formula from either supplier, it would
be forced to obtain a rubber formulation from another source. There can be no
assurance that another supplier would be able to develop an acceptable
formulation or be able to provide the Company with sufficient amounts of rubber.
If the Company is unable to obtain a satisfactory rubber formulation, the
quality of its prophy cups could be negatively impacted and the Company could
suffer a loss of reputation and a decline in sales.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     On July 22, 1996, under the terms of a Revolving Credit and Term Loan
Agreement (Loan Agreement) with a bank, the Company borrowed $16.5 million to
acquire Denticator and to pay off other existing debt. The Loan Agreement
consisted of a term loan of $12.0 million and a revolving line of credit with a
maximum borrowing capacity of $6.5 million. On April 1, 1997, the Loan Agreement
was amended to increase the revolving line of credit capacity to $7.0 million.
 
     Borrowings bear interest at prime minus .5%, payable monthly and are
collateralized by all assets of the Company, stock of its subsidiaries and a
pledge of stock by its majority stockholder. As of December 31, 1996, the unused
portion of the line of credit amounted to $1.2 million. Although the line of
credit is due and payable on December 1, 1999, the Company may retire some or
all of the outstanding borrowings during 1997 and therefore, the Company's line
of credit borrowings are classified as a current liability.
 
     The Company is limited under the terms of the Loan Agreement in its ability
to make loans and investments, incur additional debt, pay dividends and sell
significant assets, among other things, without the consent of the bank.
 
     As of December 31, 1996, maturities of long-term debt including future
minimum lease payments are as follows:

13. PUTTABLE COMMON STOCK:
 
     In accordance with the provisions of certain stockholder agreements,
employees who have purchased common stock from a stockholder at an appraised
value are obligated to sell their shares upon cessation of employment or may
sell during employment to either the majority stockholder of the Company or the
Company. The price at which the stock is repurchased is based on the appraised
value of the Company as of the latest fiscal year-end. During 1996, the Company
purchased 42,434 shares for $329 and resold 600 shares for $5.
 
     The Company and the holders of the puttable common stock have agreed to
terminate the stockholder agreements contemporaneous with and subject to the
completion of the common stock offering. Therefore, all outstanding shares of
the puttable common stock will be reflected in stockholders' equity upon
completion of

15. SUPPLEMENTARY EARNINGS PER SHARE:
 
     As discussed in Note 20, the Company plans to retire substantially all of
its outstanding indebtedness using the net proceeds from the sale of common
stock. Assuming the Company's revolving line of credit and long-term borrowings
were retired as of January 1, 1996, supplementary earnings per share would be
$.68 and $.36 (unaudited) for the year ended December 31, 1996, and six months
ended June 30, 1997, respectively, reflecting the elimination of interest
expense, net of income taxes, of $614 for 1996 and $373 for the six months ended
June 30, 1997. Supplementary earnings per share assumes 4,444,003 and 4,409,728
weighted average shares outstanding for 1996 and the six months ended June 30,
1997, respectively, plus 1,275,000 and 1,480,000 shares, representing those
shares of common stock sold at an initial public offering price of $11.00 per
share, the application of the net proceeds therefrom sufficient to retire $12.6
and $14.7 million of average outstanding borrowings for 1996 and the six months
ended June 30, 1997, respectively.
 
16. EMPLOYEE BENEFITS:
 
     The Company has a nonqualified bonus plan under which 5% of base
compensation is paid annually to full-time employees in Missouri and Texas who
are at least 25 years of age and have at least three years of service with the
Company. Compensation expense related to this plan totaled $65, $80 and $106 in
1994, 1995 and 1996, respectively. The Company also has a nonqualified profit
sharing plan for its employees in Missouri and Texas. Compensation expense
related to this plan was $174, $192 and $190 in 1994, 1995 and 1996,
respectively, and is based on the overall profitability of the Company
(excluding Denticator). Denticator has a nonqualified profit sharing plan for
certain employees in California. Compensation expense related to this plan was
$59 in 1996.
 
17. RELATED-PARTY TRANSACTIONS:
 
     The Company leases a portion of its office space to, pays for services from
and loans funds to, a corporation in which two stockholders have an equity
interest. Rental and other income from such corporation totaled $18 in 1994, $17
in 1995 and $15 in 1996. As of December 31, 1995 and 1996, the Company had an
unsecured note receivable of $76 and $58, respectively, from such corporation.
The Company paid an aggregate of $9, $14 and $10 for services provided to such
corporation in 1994, 1995 and 1996, respectively.
 
     The Company sells products to, and pays for services from, a corporation in
which a stockholder has an equity interest. Net sales to such corporation
totaled $47 in 1994, $15 in 1995 and $34 in 1996. Amounts paid for services
totaled $27 in 1994, $38 in 1995 and $41 in 1996.
 
     The Company pays for services from and has outstanding trade receivables
due from a corporation in which a stockholder has personally guaranteed a loan.
Net purchases totaled $18 in 1996 and trade receivables due totaled $84 at
December 31, 1996.

                            YOUNG INNOVATIONS, INC.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     The Company is a party to agreements with five trusts for the benefit of
children of the majority stockholder, pursuant to which the nonselling trusts
and the Company have rights of first refusal to purchase common stock held by
the trusts desiring to sell their common stock. These agreements will terminate
upon completion of the initial public offering of common stock (see Note 20).
 
     In connection with the acquisition of Denticator, an employment agreement
(the Agreement) with Denticator's President and Chief Executive Officer was
executed. The Agreement provides for a base annual salary of $120 and delivery
of shares of common stock. If the individual is employed by the Company on July
22, 1998, the Company will deliver common stock in the number of shares equal to
$800 divided by the last reported sale price. The employment agreement also
provides the right to require the Company to repurchase up to 40% of the stock
by providing 10 days advance written notice before receipt. The employee has
agreed not to compete with the Company for a period of two years after
expiration or termination of the employment agreement. The Company is accruing
$800 evenly over the two year period and recorded $176 of compensation expense
for the year ended December 31, 1996.
 
     In April 1997, Denticator purchased the assets of Hot Plastics
Technologies, Inc. (HPT), a company that had provided injection molding services
for Denticator. The President and Chief Executive Officer of Denticator and the
Chief Financial Officer of the Company owned 70% and 5%, respectively, of the
stock of HPT. The sole consideration paid by Denticator for the acquisition was
the assumption of HPT's liabilities, which aggregated $606 and included a note
payable to the President and Chief Executive Officer of Denticator of $104. The
terms of the acquisition were negotiated for Denticator by the Chief Executive
Officer of the Company. The Company paid HPT an aggregate of $213 (unaudited)
for injection molding services between January 1, 1997, and the date of HPT's
acquisition by Denticator.
 
18. CONTINGENCIES:
 
     The Internal Revenue Service (IRS) conducted a routine examination of the
Company's federal income tax returns, excluding Lorvic, for the tax years ended
December 31, 1993 and 1994. In February 1996, Young Dental received a notice of
proposed adjustments from the IRS proposing to increase federal income tax by
$250. The Company disagreed with the proposed adjustments and contested them.
Two issues have been resolved for $25. The remaining issue has a proposed
adjustment of $80 and is being contested. In the opinion of management, after
considering existing liabilities, the ultimate outcome of this examination will
not have a material adverse effect on the financial position or results of
operations of the Company.
 
     The IRS examined Lorvic's federal income tax returns for the years ended
March 31, 1992 through 1995 and proposed deficiencies in federal income taxes
for those years in an aggregate amount of $766 due to the classification of
certain intangible assets. Lorvic has filed two petitions with the United States
Tax Court contesting these proposed deficiencies. The first of these petitions,
which relate to the years ended March 31, 1992 and 1993, is scheduled for trial
in October, 1997. In accordance with the Agreement, the previous stockholders of
Lorvic are responsible for the settlement of this matter to the extent of $700
held in the tax contingencies escrow fund plus earnings thereon together with
$200 from the general contingencies fund to cover any interest and penalties
related to such matters. These funds are expected to be sufficient to satisfy
any resulting payments to the IRS.
 
     In May 1997, two former employees of Young Dental and a corporation formed
by them filed a Petition against Young Dental in the Circuit Court for the City
of St. Louis, Missouri (the Current Action). The Current Action results from an
action brought in 1993 by Young Dental against the same former employees and
corporation in the Federal District Court for the Eastern District of Missouri
(the Prior Action), alleging, among other things, patent infringement and
misappropriation of trade secrets. The Prior Action was resolved in favor of the
former employees and their corporation. In each of three counts alleging
malicious prosecution and three counts alleging abuse of process, plaintiffs in
the Current Action seek damages against Young Dental in unspecified amounts in
excess of $25. Plaintiffs also seek punitive damages. While the Current

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
Action is in its very early stages and discovery has yet to be commenced, based
upon the advice of legal counsel, the Company believes it has defenses to each
of plaintiffs' claims.
 
     In the opinion of management, the ultimate outcome of these claims and
lawsuit will not have a material adverse effect on the financial position or
results of operations of the Company.
 
19. ACCOUNTING STANDARDS NOT IMPLEMENTED:
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS 128),
which establishes standards for computing and presenting earnings per share.
SFAS 128 replaces the presentation of primary earnings per share with a
presentation of basic earnings per share. It also requires dual presentation of
basic and diluted earnings per share on the face of the income statements for
all entities with complex capital structures and requires a reconciliation of
the numerator and the denominator of the basic and diluted earnings per share
computations. The Company is required to adopt the provisions of SFAS 128 during
the quarter ending December 31, 1997, and all prior period earnings per share
data presented must be restated. The adoption of SFAS 128 is not expected to
have a significant impact on the Company's previously reported or prospective
earnings per share amounts.
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS
130), which establishes standards for reporting and displaying comprehensive
income and its components. The Company is required to adopt the provisions of
SFAS 130 no later than the quarter ending March 31, 1998. The adoption of SFAS
130 is not expected to have a material effect on the Company's financial
position or results of operations.
 
20. SUBSEQUENT EVENTS:
 
     In September 1997, the Company prepared and filed a registration statement
on Form S-1 with the U.S. Securities and Exchange Commission with respect to a
proposed initial public offering of up to 2,300,000 shares of common stock,
including an overallotment option of 300,000 shares (the Offering). A portion of
the net proceeds will be used to retire the revolving line of credit and
long-term borrowings (see Note 15). On October   , 1997, in connection with the
Offering, the Company effected a 1.2 for one stock split of each outstanding
share of common stock in the form of a stock dividend. All share and per share
information have been retroactively restated to reflect this stock split.
 
     In contemplation of and subject to the completion of the Offering, the
Company established a stock option plan whereby the compensation committee of
the Board of Directors will grant key employees incentive or nonqualified
options at fair market value. The maximum number of shares which can be issued
under the stock option plan is 350,000 shares. No options have been granted
under the plan.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
             FOR THE PERIOD FROM APRIL 1, 1995, THROUGH MAY 4, 1995
            (DOLLARS IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
1. SIGNIFICANT ACCOUNTING POLICIES:
 
NATURE OF BUSINESS
 
     Lorvic Holdings, Inc. is the parent company of Lorvic Corporation which is
engaged in the development, design and manufacturing of professional dental
products, collectively, the "Company."
 
CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary. Intercompany accounts and transactions have
been eliminated in consolidation.
 
CASH AND CASH EQUIVALENTS
 
     All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents.
 
INCOME TAXES
 
     The Company has accounted for income taxes under SFAS No. 109, an asset and
liability approach to accounting and reporting for income taxes. Deferred income
taxes are provided for temporary differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities.
 
EARNINGS PER SHARE
 
     Earnings per share is computed on net income using the weighted average
number of common shares outstanding during the period (25,000 shares).
 
2. COMMON STOCK:
 
     Class A and Class B common stockholders, voting separately as a class, are
entitled to elect three and four directors, respectively, to the Company's Board
of Directors. Each Class A director is entitled to one vote, and each Class B
director is entitled to four votes.
 
     Each outstanding share of Class B common stock is convertible into equal
shares of Class A common stock in the event there is a public offering of the
common stock of the Company or at the option of certain stockholders contingent
upon certain ownership conditions being satisfied.
 
     The Company has a stock forfeiture agreement with certain stockholders
whereby the stockholders agreed to forfeit a portion of their shares of Class A
and Class B common stock to the Company, without payment, provided certain
annual earnings targets, as defined, are fulfilled for each of the five years in
the period ended March 31, 1995. The date on which the shares are to be
forfeited is the earlier of the sale of the Company or the date upon which the
March 31, 1995, financial statements are received by the Company. The earnings
targets were met for each of the five years and cumulatively resulted in 1,250
shares (851 shares of Class B common stock and 399 shares of Class A common
stock) eligible for forfeiture to the Company.
 
     Concurrent with the stock forfeiture agreement, the Company entered into a
stock option agreement with an officer and stockholder of the Company. Under the
terms of this agreement, the officer has the option to purchase the forfeited
shares at their par value of $.01 per share. The officer may exercise the option
on or up to five years subsequent to the forfeiture date.
 
     On May 4, 1995, the date the Company was acquired (see Note 6), 1,250
shares of common stock were forfeited to the Company, and simultaneously, the
officer exercised the stock options and purchased the shares

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANT
 
To Denticator International, Inc.:
 
     I have audited the accompanying statements of operations and accumulated
deficit and cash flows of Denticator International, Inc. for the period from
April 1, 1996, through July 22, 1996. 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 the 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 results of its operations and its cash flows for
the period from April 1, 1996, through July 22, 1996, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
            FOR THE PERIOD FROM APRIL 1, 1996, THROUGH JULY 22, 1996
 
1. ORGANIZATION AND NATURE OF BUSINESS:
 
     Denticator International, Inc. (the Company) was incorporated on March 13,
1991, in the state of California as a wholly owned subsidiary of Bio-Dental
Technologies, Inc. (BTC).
 
     On March 31, 1991, BTC sold all of the outstanding stock of the Company.
The sale of the stock incorporated a licensing agreement (Note 2) which gave the
Company exclusive manufacturing rights over the "Denticator" product line. The
"Denticator" product line was first introduced in 1931 and included a series of
dental devices for use in professional dentistry.
 
     On March 31, 1991, in conjunction with the exclusive agreement referenced
above, the Company acquired the following assets from BTC in exchange for a
promissory note for $600,569:
 
<TABLE>

Inventories...............................................   535,139

                                                            $600,569

</TABLE>
 
     On July 22, 1996, the Company consummated a plan to sell substantially all
of its assets and liabilities to Young Innovations, Inc. (Young) in exchange for
$50,000 cash and the assumption of all book liabilities of the Company. Young
simultaneously purchased the licensing agreement between the Company and BTC
(Note 2). Young formed a new corporation, Denticator International, Inc., a
Missouri corporation, to manufacture and distribute the "Denticator" product
line.
 
     These statements and accompanying notes present the results of the
Company's operations and cash flows for the period from April 1, 1996, through
July 22, 1996. This short reporting period was elected by management to coincide
with the sale of substantially all of the assets and liabilities of the Company
as described above.
 
2. EXCLUSIVE LICENSING AGREEMENT:
 
     On March 31, 1991, the Company entered into an exclusive licensing
agreement with BTC for the manufacture of the "Denticator" line of dental
products. Under this agreement, the Company owes a monthly royalty equal to the
greater of $30,000 or 17% of net sales from the "Denticator" product line.
Additional royalties are payable if the Company achieves certain levels of
profitability.
 
     As of January 1, 1995, the Company increased the minimum monthly royalty
payable to BTC to $43,000 per month in exchange for BTC waving the provision in
the agreement whereby BTC could purchase products made by the Company at
specified prices.
 
     The licensing agreement is for a period of four (4) years. At the
expiration of this period, the Company has the option to pay BTC a lump sum
equal to 1.5 times the average annual sales, reduced by 50% of the additional
royalties paid, to acquire the rights to the "Denticator" product line. If this
option is not exercised, the two companies may mutually agree to renew the
licensing agreement at terms negotiated at that time. As of the audit reporting
date, an offer to buy the Company had been accepted which will assign all rights
under this licensing agreement to Young. (Note 1).
 
     During the period from April 1, 1996, through July 22, 1996, the Company
incurred BTC royalties under the licensing agreement totaling $361,675 and paid
$307,294.

contribution carryforward of approximately $172,500. The charitable contribution
carryforward, if unused, will expire in 1997.

period from April 1, 1996, through July 22, 1996.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 351.355 of the Missouri General and Business Corporation Law,
Article Ten of the Registrant's Certificate of Incorporation and Article VI of
the Registrant's Bylaws provide for indemnification of the Registrant's
directors and officers in a variety of circumstances, which may include
liabilities under the Securities Act of 1933, as amended. The Registrant intends
to obtain director and officer insurance coverage.
 
     The Underwriting Agreement (Exhibit 1 hereto) provides for indemnification
by the Underwriters of the Registrant, each of its directors, each of its
officers who signed the Registration Statement and each person who controls the
Registrant within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"), from certain liabilities under the securities laws.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
     In August 1995, the Registrant, as part of its organization as the holding
company for Young Dental, issued 4,450,214 shares of its Common Stock to the
existing stockholders of Young Dental in exchange for all of the outstanding
shares of common stock of Young Dental. In December 1996 and in February 1997,
respectively, the Registrant sold an aggregate of 2,520 shares of its Common
Stock to two purchasers subject to appropriate resale restrictions. None of the
foregoing shares were registered under the Securities Act and all were issued
pursuant to available exemptions from registration under the Securities Act.
 
ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.
 
     (A) EXHIBITS.
 
     A list of exhibits is set forth in the Exhibit Index appearing elsewhere in
this Registration Statement and is incorporated herein by reference.
 
     (B) FINANCIAL STATEMENT SCHEDULES.
 
     Attached hereto is Schedule II -- Valuation and Qualifying Accounts.
 
ITEM 17. UNDERTAKINGS.
 
     A. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities other than the payment by the Registrant of expenses
 
                                      II-1
<PAGE>   70
 
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     B. The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Underwriting Agreement certificates
in such denominations and registered in such names as required by the
Underwriters to permit prompt delivery to each purchaser.
 
     C. 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 Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act of 1933 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 offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

     After the stock split discussed in Note 20 to the consolidated financial
statements is effected, we expect to be in a position to render the following
audit report.
 
ARTHUR ANDERSEN LLP
 
                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Young Innovations, Inc.:
 
     We have audited in accordance with generally accepted auditing standards,
the consolidated financial statements of Young Innovations, Inc. and
subsidiaries included in the Young Innovations, Inc. Form S-1 Registration
Statement and have issued our report thereon dated March 31, 1997 (except with
respect to matters discussed in Note 20, as to which the date is October   ,
1997). Our audits were made for the purpose of forming an opinion on those
statements taken as a whole. Schedule II included in this Form S-1 Registration
Statement is the responsibility of the Company's management and is presented for
the purpose of complying with the Securities and Exchange Commission's rules and
is not part of the basic financial statements. This schedule has been subjected
to the auditing procedures applied in the audits of the basic financial
statements and, in our opinion, fairly states in all material respects the
financial data required to be set forth therein in relation to the basic
financial statements taken as a whole.

of the stockholders entitled to vote with respect to the subject matter
thereof.

may change the membership of any committee or amend or restate the resolution
designating the committee.  Each committee shall keep a record of proceedings

given.

         Section 5.1.   Form.  The shares of the Corporation shall be 
represented by certificates; provided, however, that the Board of Directors 
may provide by resolution or resolutions that some or all of any or all

Certificates of stock in the Corporation, if any, shall be signed by or in the
name of the Corporation by the Chairman of the Board or the President or a Vice
President and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary of the Corporation.  Where a certificate is countersigned

Corporation, or by a registrar, the signatures of the Chairman of the Board,
the President or an Executive Vice President or Vice President and the
Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary
may be facsimiles.  In case any officer, transfer agent or registrar who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such officer, transfer agent or registrar before such
certificate is issued, the certificate may be issued by the Corporation with
the same effect as if such officer, transfer agent or registrar were such
officer, transfer agent or registrar at the date of its issue.

         Section 5.2.   Transfer.  Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to

of a certificate for any stock of the Corporation, a new certificate of stock
or uncertificated shares in place of any certificate therefor issued by the

of Directors may in its discretion require the owner of the lost, destroyed or
stolen certificate, or his legal representative, to give the Corporation a
bond, in such sum and in such form and with such surety or sureties as it may
direct, to indemnify the Corporation against any claim that may be made against
it with





                                     -8-

respect to a certificate alleged to have been lost, destroyed or stolen.


                                   ARTICLE VI

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Section 6.1.  The Corporation shall indemnify any director, officer or
employee who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Corporation) by reason of the fact that he is or was a director,
officer, employee or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

         Section 6.2.  The Corporation shall indemnify any director, officer or
employee who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the Corporation unless and only to
the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case,





                                     -9-
<PAGE>   10

such person is fairly and reasonably entitled to indemnity for such expenses
which such court shall deem proper.

         Section 6.3.  To the extent that a director, officer or employee of
the Corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in Sections 1 and 2 of this article,
or in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith.

         Section 6.4.  Any indemnification under Sections 6.1 and 6.2 of this
article (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of
the director, officer or employee is proper in the circumstances because he has
met the applicable standard of conduct set forth in Sections 6.1 and 6.2. Such
determination shall be made (1) by the Board of Directors by a majority vote of
Directors who are or were not parties to such action, suit or proceeding, even
if they do not constitute a quorum of the entire Board, or (2) if there are no
such directors or if such directors so direct, then either (i) by independent
legal counsel in a written opinion, or (ii) by the Stockholders.

         Section 6.5.  Expenses incurred in defending a civil or criminal
action, suit or proceeding may be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding as authorized by the Board
of Directors upon receipt of an undertaking by or on behalf of the director,
officer, employee or agent to repay such amount unless it shall ultimately be
determined that he is entitled to be indemnified by the Corporation under this
article.

         Section 6.6.  The Corporation shall indemnify any director, officer or
employee who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, (i) arising under the Employee
Retirement Income Security Act of 1974 or regulations promulgated thereunder,
or under any other law or regulation of the United States or any agency or
instrumentality thereof or law or regulation of any state or political
subdivision or any agency or instrumentality of either, or under the common law
of any of the foregoing, against expenses (including attorneys' fees),
judgments, fines, penalties, taxes and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
by reason of the fact that he is or was a fiduciary, disqualified person or
party in interest with respect to an employee benefit plan covering employees
of the Corporation or of a subsidiary corporation, or is or was serving in any
other capacity with respect to such plan, or has or had any obligations or
duties with respect to such plan by reason of such laws or regulations,
provided that such person was or is a director, officer or employee of the
Corporation, or (ii) in connection





                                    -10-
<PAGE>   11

with any matter arising under federal, state or local revenue or taxation laws
or regulations, against expenses (including attorneys' fees), judgments, fines,
penalties, taxes, amounts paid in settlement and amounts paid as penalties or
fines necessary to contest the imposition of such penalties or fines, actually
and reasonably incurred by him in connection with such action, suit or
proceeding by reason of the fact that he is or was a director, officer or
employee of the Corporation, or is or was serving at the request of the
Corporation as a director, officer or employee of another corporation,
partnership, joint venture, trust or other enterprise and had responsibility
for or participated in activities relating to compliance with such revenue or
taxation laws and regulations; provided, however, that such person did not act
dishonestly or in willful or reckless violation of the provisions of the law or
regulation under which such suit or proceeding arises.  Unless the Board of
Directors determines that under the circumstances then existing, it is probable
that such director, officer or employee will not be entitled to be indemnified
by the Corporation under this section, expenses incurred in defending such suit
or proceeding, including the amount of any penalties or fines necessary to be
paid to contest the imposition of such penalties or fines, shall be paid by the
Corporation in advance of the final disposition of such suit or proceeding upon
receipt of an undertaking by or on behalf of the director, officer or employee
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Corporation under this section.

         Section 6.7.  The indemnification provided by this article shall not
be deemed exclusive of any other rights to which those indemnified may be
entitled under any by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding such office, and shall continue as to
a person who has ceased to be a director, officer or employee and shall inure
to the benefit of the heirs, executors and administrators of such a person.

         Section 6.8.  The Corporation may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of
the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not he would be entitled to indemnity against such liability under
the provisions of this article.

         Section 6.9.  To the extent determined by the Board of Directors, the
Corporation shall have the power to give indemnity to the fullest extent
permitted by Section 351.355 of the General and Business Corporation Law of
Missouri, as the same may be amended and supplemented or by any successor
thereof, in addition





                                    -11-
<PAGE>   12

to the indemnity authorized by this Article VI to any person who is or was a
director, officer, employee or agent, or to any person who is or was serving at
the request of the Corporation, as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise.

shall be fixed by resolution of the Board of Directors.

         Section 7.2.    Corporate Seal.  The corporate seal shall be in such

transmission.  Unless otherwise provided in these By-laws, notice by mail shall
be effective on the date it is mailed. Notice given by facsimile transmission

be given under law or the provisions of the Articles of Incorporation or these
By-Laws, a waiver thereof in writing, signed by the person or persons entitled
to said notice, whether before or after the time stated therein, shall be
deemed equivalent to notice.

                                   AMENDMENTS

         Section 8.1.    In General.  These By-Laws may be altered, amended or
repealed or new By-Laws may be adopted by the Board of Directors.  The fact
that the power to amend, alter, repeal or adopt the By-Laws has been conferred
upon the Board of Directors shall not divest the stockholders of the same
powers.

                            VIII.  DEATH OF EMPLOYEE

                         IX.  TERMINATION OF EMPLOYMENT

  9.1  TERMINATION BY CORPORATION.  Corporation may terminate Employee's
employment pursuant to this Agreement in the event that Employee during the
term of this Agreement shall be in Actual Default (as defined herein) under any
provision of this Agreement, or if Employee has committed acts of gross
negligence, dishonesty or misconduct in carrying out his obligations or
responsibilities to the Corporation, as determined in the reasonable discretion
of the Board of Directors of the Corporation, by giving at least thirty (30)
days prior written notice to Employee of Corporation's intention to terminate
this Agreement.  In the event of such termination by Corporation, Employee
shall have the right to reasonable access to documents

and records of Corporation in a subsequent investigation by Employee
challenging the grounds for termination.

  In the event of such termination by Corporation, Corporation shall be
obligated to continue to pay Employee the salary due Employee under this
Agreement up to the termination date stated in said written notice so long as
Employee continues to be ready, willing and able to perform all of Employee's
duties in accordance with this Agreement.

  9.2  TERMINATION BY EMPLOYEE.  Employee may terminate Employee's employment
pursuant to this Agreement in the event that Corporation, during the term of
this Agreement, shall be in Actual Default (as defined herein) under any
provision of this Agreement, by giving at least sixty (60) days prior written
notice to Corporation of Employee's intention to terminate this Agreement.

  In the event of any such termination by Employee, Corporation shall continue
to pay Employee the salary due Employee under this Agreement up to the
termination date stated in Employee's written notice so long as Employee
continues to perform all of Employee's duties in accordance with the terms of
this Agreement and so long as there is no earlier termination date under any
notice given by Corporation.

  9.3  COOPERATION BY EMPLOYEE.  Following any such notice of termination,
Employee shall fully cooperate with Corporation in all matters relating to the
winding up of Employee's pending work on behalf of Corporation and the orderly
transfer of any such pending work to such other employees of Corporation as may
be designated by the Corporation; and to that end Corporation shall be entitled
to such full-time or part-time services of Employee as Corporation may
reasonably require during all or any part of the period from the time of giving
any such notice until the effective date of such termination.

  9.4  SETTLEMENT OF ACCOUNTS.  After any termination of this Agreement, all
compensation and amounts due to Employee with respect to work performed or
expenses incurred prior to the date of termination shall be reconciled with
amounts due to Corporation from Employee.  Each party shall be entitled to
offset against any amounts that may be due to the other party such amounts as
are due from such other party to it or him.  The parties shall proceed
expeditiously to accomplish the foregoing, and the resulting amount due from
one party to the other shall be paid promptly after it is determined.

served by Employee during the term of this Agreement shall belong to and remain
the property of Corporation.

                         XI.  CONFIDENTIAL INFORMATION

  11.1  NONDISCLOSURE BY EMPLOYEE.  Employee will not, except as authorized by
Corporation, during or at any time after the termination of Employee's
employment with Corporation, directly or indirectly, use for himself or others,
or disclose, communicate, divulge, furnish to, or convey to any other person,
firm, or corporation, any secret or confidential information, knowledge or data
of Corporation or that of third parties obtained by Employee during the period
of his employment with Corporation and such information, knowledge or data
includes, without limitation, the following:

  a) Secret or confidential matters of a technical nature such as, but not
     limited to, methods, know-how, formulae, compositions, processes,
     discoveries, manufacturing techniques, inventions, computer programs, and
     similar items or research projects involving such items;

  b) Secret or confidential matters of a business nature such as, but not
     limited to, information about costs, purchasing, profits, market, sales or

with Corporation, or at any other time upon Corporation's written request,
shall deliver promptly to Corporation all drawings, blueprints, manuals,
letters, notes, notebooks, reports, sketches, formulae, computer programs and
similar items, memoranda, lists of customers, and all other materials and
copies thereof relating in any way to Corporation's business which contain
confidential information and which were in any way obtained by Employee during
the term of his employment with Corporation which are in his possession or
under his control; and Employee will not make or retain any copies of any of
the foregoing and will so represent to Corporation upon termination of his
employment.

person, firm, or corporation employing Employee or evidencing an intention to
employ Employee as to the existence and provisions of this Agreement.

information or other commercial ideas mentioned





                                     -6-
<PAGE>   7

herein are unique and that the disclosure or use of such matters or any other
secret or confidential information other than in furtherance of the business of
Corporation would reasonably be expected to result in irreparable harm to
Corporation; and that in addition to whatever other remedies Corporation and/or
its successors or assigns may have at law or in equity, Employee specifically
covenants and agrees that, in the event of default under or breach of this
Agreement, Corporation and/or its successors and assigns shall be entitled to
apply to any court of competent jurisdiction to enjoin any breach, threatened
or actual, of the foregoing covenants and promises by Employee, and/or to sue
to obtain damages for default under or any breach of this Agreement.  In the
event of default under or breach of this Agreement, Employee hereby agrees to
pay all costs of enforcement and collection of any and all remedies and damages
under this Agreement, including reasonable attorneys' fees as determined by a
court of competent jurisdiction.

                        XII.  LIMITATION ON COMPETITION

  12.1  NONCOMPETITION AGREEMENT.  During the period of employment and for a
period of two (2) years after expiration or termination of this Agreement, for
cause or by Employee, Employee shall not, within the United States of America,
directly or indirectly as an owner, employee, consultant or otherwise,
individually or collectively, acquire an interest in, become an employee of or
consultant to a dental manufacturing or distribution business.  Employee agrees
that the area, in light of the character of the industry, and the duration of
this limitation are reasonable under the circumstances, considering Employee's
position with Corporation and other relevant factors, and that in all
likelihood this will not constitute a serious handicap to Employee in securing
future employment.

  12.2  NONSOLICITATION AGREEMENT.  Employee will not, either during employment
or during the period of two (2) years after expiration or termination of this
Agreement, for cause or by Employee, directly or indirectly, either for himself
or for any other person, firm, or corporation, take any action or perform any
services which are designed to or in fact call upon, compete for, solicit,
divert, or take away, or attempt to divert or take away, any of the customers
of Corporation; this prohibition includes customers existing at the present
time or prospective or past customers solicited, sold to or served by
Corporation during the five (5) years prior to termination or expiration of
this Agreement.

  12.3  NON-HIRE AGREEMENT.  Employee will not, either during employment or
during the period of two (2) years after expiration or termination of this
Agreement, for cause or by Employee, directly or indirectly, either for himself
or for any other person, firm, or corporation, induce, employ or attempt to
employ





                                     -7-
<PAGE>   8

any person who is at that time, or has been within six (6) months immediately
prior thereto, employed by Corporation.

  12.4  REMEDIES.  It is further agreed that, if Employee shall violate the
foregoing prohibitions, Corporation shall be entitled to seek specific
performance of these covenants, and Employee shall pay all costs and attorneys'
fees, as determined by a court of competent jurisdiction, incurred by
Corporation in enforcing the aforesaid covenants if Corporation is successful
in so doing after a final adjudication of the matter.  If any of the foregoing
covenants is not enforceable to the full extent provided, it shall be and
remain enforceable to the extent permitted by law, and a court is authorized by
the parties to modify such covenant to make it reasonable and, as so modified,
enforce it.

  12.5  TERMINATION OF PROVISIONS.  Notwithstanding the provisions hereof
regarding termination of this Agreement, the provisions of this Section shall
remain in full force and effect (including any extensions or renewals) provided
for hereunder.  However, in the event that this Agreement is terminated as a
result of (i) Corporation being in Actual Default, (ii) Corporation filing for
bankruptcy, having an involuntary petition filed against it which is not
dismissed within sixty (60) days, ceasing operations, dissolving or becoming
insolvent, or (iii) Corporation terminating Employee without cause, the
provisions of this Article shall be null and void.

                           XIII.  BINDING ARBITRATION

  Except for matters arising under Article XII, any controversy or claim
arising out of or relating to this Agreement, or the breach thereof, shall be
settled by arbitration in accordance with the Rules of the American Arbitration
Association at a mutually convenient location agreed to by the parties or the
arbitrators, and the parties hereby agree to be bound by the results thereof.
Each party shall choose one arbitrator and a third arbitrator shall be chosen
by the two arbitrators so chosen by the parties.  A judgment upon any award
rendered by a majority opinion of the arbitrators so chosen may be entered in
any court having jurisdiction thereof.

                              XIV.  ACTUAL DEFAULT

  In the event either party believes that the other party has failed to fulfill
any of his or its obligations under this Agreement, the party aggrieved by such
default shall give the other party written notice of such default specifying
the nature thereof.  If within thirty (30) days after the giving of such
notice, the alleged defaulting party has failed or refused to remedy such
default, the party aggrieved by such alleged default may by notice in writing
declare the alleged defaulting party to be in actual default ("Actual Default")
of this Agreement and





                                     -8-
<PAGE>   9

proceed in the manner otherwise provided for herein.  The provisions of this
Section are intended to provide a means whereby the party alleged to be in
default under this Agreement will have an opportunity to cure any such alleged
default before the aggrieved party shall be entitled to attempt to terminate
this Agreement.  The giving of such notice and the expiration of the thirty
(30) day period provided for herein shall not, however, prevent the alleged
defaulting party from establishing that no default did in fact exist.

                            XV.  GENERAL PROVISIONS

  15.1  WAIVER.  The waiver by either party of a breach or violation of any
provision of this Agreement shall not operate as or be construed to be a waiver
of any subsequent breach hereof.

  15.2  SEVERABILITY.  Should any one or more sections of this Agreement be
found to be invalid, illegal, or unenforceable in any respect, the validity,
legality and enforceability of the remaining sections contained herein shall
not in any way be affected or impaired thereby.  In addition, if any section
hereof is found to be partially enforceable, then it shall be enforced to that
extent.

  15.3  NOTICES.  Any and all notices required or permitted to be given under
this Agreement shall be sufficient if furnished in writing and personally
delivered or sent by registered or certified mail to the last known residence
address of Employee or to Corporation at its principal office at 13705
Shoreline Court East, Earth City, Missouri 63045 or such other place as it may

Agreement to a third party which purchases substantially all of the then assets

JEFFREY LECK ("LECK"), JOHN F. KIRTLEY ("KIRTLEY"), RICHARD C. NEMANICK

with each Stockholder owning that number of shares of the Class A Common Stock,

par value $.01 per share (the "Class B Common Stock") (collectively, the

owned by the Stockholders, being all of the issued and outstanding shares of
capital stock of the Company, are collectively referred to herein as the
"Shares".  The Stockholders desire to sell to the Purchaser, and the Purchaser
desires to purchase from the Stockholders, all of the Shares, on the terms and
subject to the conditions contained in this Agreement.

    NOW, THEREFORE, in consideration of the premises and the mutual
representations hereinafter set forth, the parties hereto hereby agree as
follows:


                                   ARTICLE I

                          PURCHASE AND SALE OF SHARES

    1.1.     TRANSFER OF SHARES.  On the terms and subject to the conditions of
this Agreement, at the Closing, the Stockholders shall sell, transfer, convey
and assign to the Purchaser, and the Purchaser shall purchase and acquire from
the Stockholders, all of the Shares, free and clear of all Encumbrances.  As
used herein, the term "Encumbrances" shall mean and include security interests,
mortgages, liens, pledges, charges, easements, reservations, restrictions,
rights of way, options, rights of first refusal and all other encumbrances,
whether or not relating to the extension of credit or the borrowing of money.

Price") to be paid by the Purchaser to the Stockholders for the Shares shall be
(i) $13,000,000 plus (ii) the amount of all cash or cash equivalents of the
Company in excess of $300,000 (the "Excess Cash") determined as of the day
prior to the Closing Date (the "Valuation Date"), plus or minus (iii) any
Purchase Price Adjustment made pursuant to Section 1.4 hereof, plus (iv) the
Contingent Payment (defined hereafter), if any, to Nemanick.  For purposes of
this Agreement, the term "Contingent Payment" shall refer to any payments to

<PAGE>   7

pursuant to the Contingent Payment Agreement of even date herewith between
Purchaser and Nemanick.

    1.3.     PAYMENT OF THE PURCHASE PRICE.  On the Closing Date (defined
hereafter) the Purchaser shall pay or cause the Company or an affiliate of the
Company simultaneously with the Closing to pay the Purchase Price by wire
transfer of immediately available funds as follows:

         (a) to the Stockholders, (i) the sum of $11,150,000 plus the Excess
Cash (such Excess Cash (the "Estimated Excess Cash Amount") to be equal to
Lorvic's best estimate, made with participation by representatives of
Purchaser, of the Excess Cash as of the close of business on the Valuation
Date) of the Company minus (ii) the Stockholder Expenses (as defined below)
such sum to be referred to as the "Initial Payment"), in the amounts and to the
accounts designated by such Stockholders and set forth on Exhibit A hereto;

         (b) to the parties and in the amounts listed on Exhibit B hereto as
payment for the expenses incurred by the Stockholders in connection with the
transactions contemplated by this Agreement (the "Stockholder Expenses");

         (c) to Boatmen's Trust Company ("Boatmen's"), as escrow agent (the
"Seller Escrow Agent") pursuant to the terms of the Seller Escrow Agreement,
dated as of the Closing Date among the Purchaser, the Stockholders and the
Escrow Agent, substantially in the form of Exhibit C hereto (the "Seller Escrow
Agreement"), the sum of $1,850,000 (the "Seller Escrow Fund");

         (d) to Boatmen's as Contingent Payment Agent (the "Contingent Payment
Agent") pursuant to the terms of the Contingent Payment Agreement dated as of
the Closing Date among the Purchaser, Nemanick and the Contingent Payment
Agent, substantially in the form of Exhibit D hereto (the "Contingent Payment
Agreement"), the sum of $500,000 (the "Contingent Payment Fund"); and

         (e) the Seller Escrow Fund shall be divided into three accounts as
follows:  (i) $100,000 thereof shall be held in an account (the "Purchase Price
Adjustment Escrow Account") to be utilized to fund the Purchase Price
Adjustment as described in Section 1.4 hereof; (ii) $700,000 shall be held in
an account (the "Tax Claim Escrow Account") to provide indemnification to
Purchaser against the Tax Claim (as defined below) as provided in Article V
hereof; and (iii) $1,050,000 thereof shall be held in an account (the "General
Escrow Account", and together with the Purchase Price Adjustment Escrow Account
and the Tax Claim Escrow Account, the "Escrow Accounts") to provide
indemnification to Purchaser as provided in Article V hereof.

    1.4.     PURCHASE PRICE ADJUSTMENT.  (a) Within 60 days after the Closing
Date, the Purchaser shall prepare and deliver to the Stockholders, (i) a
balance sheet of the Company as of the close of business on the Valuation Date
(the "Closing Balance Sheet")





                                       2
<PAGE>   8

and (ii) the Purchaser's calculation of the Net Working Capital and the Excess
Cash of the Company on the Valuation Date.  As used herein, the term "Net
Working Capital" means the current assets of the Company minus current
liabilities (excluding in such calculation the Excluded Amounts (as defined
below)) of the Company in each case determined as of the close of business on
the Valuation Date, in accordance with the Closing Balance Sheet.  The Closing
Balance Sheet shall be prepared in accordance with GAAP (as hereinafter
defined) applied in a manner consistent with the same accounting principles and
methodologies used in preparing the December Balance Sheet (as hereinafter
defined); provided, however, that if any of the accounting principles and
methodologies used in preparing the December Balance Sheet were not in
accordance with GAAP, such principles and methodologies will not be used, and
GAAP will govern.  For purposes of this Agreement, "Excluded Amounts" means (i)
cash and cash equivalents in excess of an amount equal to $300,000; (ii) the
amount of any claim or claims for refund of Federal or State income taxes
arising from tax returns filed or to be filed with respect to periods ending on
or prior to the Closing Date and resulting from any loss or deduction generated
by the Company or Lorvic in connection with the option granted to Nemanick
pursuant to the Stock Option Agreement dated as of December 28, 1989 (the
"Nemanick Option") and/or the bonus paid to Nemanick (the "Nemanick Bonus") on
May 2, 1995 (any such refunds to be referred to herein as the "Tax Refunds");
(iii) the current portion of any indebtedness required to be repaid pursuant to
Section 1.4(h) hereof; (iv) amounts accrued (if any) to reflect the Tax Claim
(as defined in Section 5.5 hereof); and (v) amounts accrued (if any) to reflect
the Plan Expenses (as defined in Section 7.01 hereof).  Cash and cash
equivalents in excess of $300,000 shall be included as a separate line item on
the Closing Balance Sheet (the "Final Excess Cash Amount").  The Purchaser
shall provide the Stockholders and their accountants with timely access, during
the Company's normal business hours, to the Company's personnel, properties,
books and records.  The costs and expenses of preparing the Closing Balance
Sheet will be borne by the Stockholders.

         (b) During the 30 days immediately following receipt of the Closing
Balance Sheet by the Stockholders, the Stockholders and their accountants shall
be entitled to review the Closing Balance Sheet and any working papers, trial
balances and similar materials relating to the Closing Balance Sheet prepared
by the Purchaser or its accountants, and the Purchaser shall provide the
Stockholders and their accountants with timely access, during  the Company's
normal business hours, to the Company's personnel, properties, books and
records.  The Closing Balance Sheet shall become final and binding upon the
parties on the thirty-first day following delivery thereof unless the
Stockholders give written notice to the Purchaser of their disagreement with
the Closing Balance Sheet (a "Notice of Disagreement") prior to such date.  Any
Notice of Disagreement shall specify in reasonable detail the nature of any
disagreement so asserted.  If a timely Notice of Disagreement is received by
the Purchasers with respect to the Closing Balance Sheet, then





                                       3
<PAGE>   9

the Closing Balance Sheet (as revised in accordance with clause (x) or (y)
below), shall become final and binding upon the parties on the earlier of (x)
the date the parties hereto resolve in writing any differences they have with
respect to any matter specified in a Notice of Disagreement or (y) the date any
matters in dispute are finally resolved in writing by the Accounting Firm (as
defined below) (the date on which the Closing Balance Sheet so becomes final
and binding being hereinafter referred to as the "Final Determination Date").
During the 30 days immediately following the delivery of any Notice of
Disagreement, the Purchaser and the Stockholders shall seek in good faith to
resolve in writing any differences which they may have with respect to any
matter specified in such Notice of Disagreement.  During such period, the
Purchaser and the Stockholders shall each have access to the other party's
working papers, trial balances and similar materials prepared in connection
with the other party's preparation of the Closing Balance Sheet and the Notice
of Disagreement, as the case may be.  At the end of such 30-day period, the
Stockholders and the Purchaser shall submit to an independent "Big 6" public
accounting firm (the "Accounting Firm") for review and resolution any and all
matters which remain in dispute and which were included in any Notice of
Disagreement, and the Accounting Firm shall reach a final, binding resolution
of all matters which remain in dispute, which final resolution shall be (A) in
writing, (B) furnished to the Purchaser and the Stockholders as soon as
practicable after the items in dispute have been referred to the Accounting
Firm, (C) made in accordance with this Agreement and (D) conclusive and binding
upon the Purchaser and the Stockholders.  The Closing Balance Sheet, with any
adjustments necessary to reflect the Accounting Firm's resolution of the
matters in dispute, shall become final and binding on the Purchaser and the
Stockholders on the date the Accounting Firm delivers its final resolution to
the parties.

    The Accounting Firm shall be Coopers & Lybrand LLP, or if such firm is
unable or unwilling to act, such other independent Big 6 public accounting firm
as shall be agreed upon by the parties hereto in writing or, if the Purchaser
and the Stockholders cannot so agree within the 30-calendar day period referred
to above, by lot from among the remaining independent Big 6 public accounting
firms willing to act.  Each party shall pay its own costs and expenses incurred
in connection with such dispute resolution, provided that the fees and expenses
of the Accounting Firm shall be borne 50% by the Purchaser and 50% by the
Stockholders, pro rata based on such Stockholders' percentage ownership of the
Company on the Closing Date.

         (c) Upon the final determination of the Closing Balance Sheet in
accordance with this Section 1.4, the following amounts will be payable in
accordance with Section 1.4(f) and the Escrow Agreement:

             (i) if (w) Net Working Capital plus (x) the amount (if any) by
which the Final Excess Cash Amount exceeds the Estimated Excess Cash Amount and
less (y) the amount (if any) by which the Final Excess Cash Amount is less than
the Estimated





                                       4
<PAGE>   10

Excess Cash Amount, and less (z) any additional adjustment pursuant to Section
1.4(d) (such sum being referred to as the "Adjustment Base") is equal to or
greater than $1,418,928 (such sum being referred to as the "Target Amount"),
the Escrow Agent shall distribute the Purchase Price Adjustment Escrow Account
to the Stockholders, and Purchaser shall pay to the Stockholders the amount, if
any, by which the Adjustment Base exceeds the Target Amount, in each case pro
rata in proportion to each Stockholder's percentage interest (each a
"Percentage Interest" and collectively, the "Percentage Interests") as set
forth on Exhibit A hereto; and

             (ii)    if the Adjustment Base is less than the Target Amount, the
Escrow Agent shall distribute to the Purchaser from the Purchase Price
Adjustment Escrow Account the amount by which the Adjustment Base is less than
the Target Amount (the "Target Differential") and shall distribute the balance
of the Purchase Price Adjustment Escrow Account to the Stockholders in
proportion to their Percentage Interests; provided that, if the Target
Differential exceeds $100,000, the entire Purchase Price Adjustment Escrow
Account shall be distributed to Purchaser and the Escrow Agent shall distribute
to Purchaser from the General Escrow Account the amount by which the Target
Differential exceeds $100,000.

Any required adjustment to the purchase price pursuant to this Section 1.4
shall be referred to as the "Purchase Price Adjustment".

         (d) If within 30 days of the Closing Date, the Purchaser shall
reasonably determine that any fixed asset (other than any molds used or to be
used in connection with the current or future production of the EZ-ON product
line) having a book value in excess of $5,000, included in the category
"Property Plant and Equipment" on the December Balance Sheet is determined to
be unnecessary for the operation of the Company's business as conducted on the
Closing Date or in a condition that renders such asset unusable as of the
Closing Date, then the Purchase Price shall be adjusted downward by the book
value of such asset, and in the event of such adjustment the Purchaser shall
cause the Company or Lorvic, as the case may be, to transfer title to such
asset to the Stockholders or as the Stockholders may direct.

         (e) The Purchaser agrees, solely with respect to the calculation of
Purchase Price Adjustments, and without restricting in any manner whatsoever
the Purchaser's right to take any such action that would not affect such
calculation, that following the Closing, the Purchaser will not take any
actions with respect to the accounting books, records, policies and procedures
of the Company on which the Closing Balance Sheet is to be based that are not
consistent with GAAP applied in the manner consistent with the past practices
of the Company.

         (f) Within thirty-three (33) days after the receipt by the
Stockholders of the Closing Balance Sheet in accordance with Section 1.4(a)
hereof, the Stockholders and Purchaser shall jointly instruct the Escrow Agent
to make the disbursements of





                                       5
<PAGE>   11

Escrow Funds required by Section 1.4(c) hereof with respect to any undisputed
amounts constituting Purchase Price Adjustments.  With respect to any items
that are the subject of a Notice of Disagreement, joint disbursement
instructions shall be given to the Escrow Agent within three (3) business days
after the Final Determination Date.

    1.5.     DELIVERY OF SHARES.  At the Closing, in consideration of the
Purchaser's delivery of the Purchase Price pursuant to Section 1.3 hereof, (a)
the Stockholders shall each deliver to the Company a certificate or
certificates representing the Shares owned by such Stockholder as set forth on
Exhibit A, duly endorsed in blank for transfer or accompanied by stock powers
duly executed in blank, sufficient in form and substance to convey to the
Purchaser good title to all of the Shares owned by such Stockholder, free and
clear of all Encumbrances and (b) the Company shall deliver to the Purchaser a
certificate registered in the name of the Purchaser, representing all of the
Shares.

    1.6.     FURTHER ASSURANCES.  Each Stockholder shall, at any time after the
Closing, upon the reasonable request of the Purchaser, do, execute, acknowledge
and deliver, and cause to be done, executed, acknowledged and delivered, all
such further acts, deeds, assignments, transfers, conveyances, powers of
attorney or assurances as may be reasonably required to transfer, convey, grant
and confirm to and vest in the Purchaser good title to all of the Shares owned
by such Stockholder, free and clear of all Encumbrances.

    3.1.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company hereby
represents and warrants to the Purchaser as follows:

the Company's and Lorvic's Charter and By-Laws (as hereinafter defined), in
each case as in effect on the date hereof.  Each of the Company and Lorvic are
duly qualified and in good standing to do business in each jurisdiction in
which such qualification is necessary because of the nature of the business
conducted by it, except where the failure to be so qualified would not have a

operations of the Company and Lorvic taken as a whole (a "Material Adverse
Effect").  As used in this Agreement, (i) the terms "Charter" and "By-Laws"
respectively mean, with respect to any corporation, those instruments that,

contemplated hereby which are listed on Exhibit E (each a "Document" and,
collectively, the "Documents") to which it is a party, to perform its
obligations under each such Document, and to consummate the transactions
contemplated by each such Document.  The execution, delivery and performance by
the Company of each Document to which it is a party and the consummation of the
transactions contemplated thereby have been duly and validly authorized by all
necessary corporate action on the part of the Company.  Each Document to which
the Company is a party is, or upon its execution and delivery will be, a valid
and binding obligation of the Company, enforceable against it in accordance
with the terms thereof.  Except as set forth on Schedule 3.1(b), neither the
execution, delivery or performance by the Company of any Document to which it
is a party, nor the consummation by the Company of the transactions
contemplated thereby, nor compliance by the Company with any of the provisions
thereof will (i) conflict with or result in a breach of any provision of the
Company's or Lorvic's Charter or By-Laws, (ii) violate any law, statute, rule
or regulation or judgment, order, writ, injunction or decree of any
Governmental Authority, in each case applicable to the Company, Lorvic or the
Shares or (iii) conflict with or result in a breach of any provision of any

Documents.  For purposes of making the representation set forth in clause (ii)
above and the immediately preceding sentence, the Company has assumed and, with

The total assets and annual net sales of the ultimate parent entity, if any, of
the Company are less than $100,000,000.

         (c) EQUITY INVESTMENTS.  Except as set forth on Schedule 3.1(c), the

interest in any Person.

         (d) FINANCIAL INFORMATION.  Schedule 3.1(d) contains complete and

to the Listed Intellectual Property, no registration relating thereto has
lapsed, expired or been abandoned or cancelled or to the Company's knowledge is
the subject of any reexamination, reissue, opposition, or cancellation
proceeding, or litigation.  The Company and Lorvic own or possess adequate and
enforceable licenses (free of Encumbrances other than Permitted Encumbrances)

know-how and confidential information) currently used by the Company and
Lorvic, or necessary to permit the Company and Lorvic to conduct their
businesses as now conducted without restriction and without further obligation
to any person except as set forth in any Intellectual Property Licenses or any
Contract (the Listed Intellectual Property and the other intellectual property
rights hereinafter collectively called the "Intellectual Property").  Schedule
3.1(k) sets forth all licenses to which the Company is a party relating to the
Intellectual Property (the "Intellectual Property Licenses").  The Company and

this Agreement.  Except as set forth on Schedule 3.1(k), neither the Company
nor Lorvic has received notice of a charge of infringement or misappropriation,
or in any material respect, infringed on or misappropriated and is not now, in
any material respect, infringing on or misappropriating any intellectual
property rights belonging to any Person based on the operations of the Company
and Lorvic within the last three years, and no claim has been made, is pending
or, to the knowledge of the Company, threatened to the effect that any
Intellectual Property is invalid or unenforceable or that the Company or Lorvic
has breached any Intellectual Property License, or that any Intellectual
Property License is terminable or cancelable.  To the Company's knowledge,
except as set forth on Schedule 3.1(k), no Person is infringing upon or
violating any of the Listed Intellectual Property in any material respect.
Except as set





                                       12
<PAGE>   18

forth on Schedule 3.1(k), no contract or agreement between the Company or
Lorvic with any party exists, and no Encumbrances other than Permitted
Encumbrances exist, which in either case would materially impede or prevent the
continued use by the Company or Lorvic of the entire right, title and interest
of the Company or Lorvic in and to any of the Intellectual Property of the
Company or Lorvic.

         (l) LABOR RELATIONS; BENEFIT PLANS.  Except as set forth on Schedule

                                       14

of Title IV of ERISA.  Neither the Company, Lorvic nor any ERISA Affiliate has
received notice to the effect that any Multiemployer Plan has any unfunded
vested benefits within the meaning of Section 4213(c) of ERISA.  The
transactions contemplated by this Agreement shall not cause the Company, Lorvic
or any ERISA Affiliate to be subject to any material liability with respect to
a Multiemployer Plan.

             (v)  The Pension Plans comply in all respects with the applicable
requirements of ERISA, meet the requirements of "qualified plans" under Code
Section 401(a) and each such Plan has received a favorable determination letter
from the Internal Revenue Service to this effect.  The Pension Plans have been
or will be timely amended and filed with the Internal Revenue Service with
respect to changes required by the Tax Reform Act of 1986, as amended, and are
being and have been administered in compliance with the Tax Reform Act of 1986,
as amended.  The Welfare Plans and Non-Qualified Pension Plans listed on
Schedule 3.1(l) and related trusts, insurance contracts or other funding
arrangements, if any, comply in form and in operation with the requirements of
ERISA and the Code.  All required reports and descriptions (including Form 5500
Annual Reports, Summary Annual Reports and Summary Plan Descriptions) have been
appropriately filed or distributed with respect to the Pension and Welfare
Plans.  The Company, Lorvic and ERISA Affiliates have complied with all
requirements of Part 6 of Subtitle B of Title I of ERISA and Code Section
4980B, and any proposed or final regulations promulgated thereunder, with
respect to the Welfare Plans.  The Non ERISA Plans listed on Schedule 3.1(l)
have been properly adopted by the Company, Lorvic and ERISA Affiliates and
administered and operated in accordance with their terms and comply with
applicable law.  No Welfare, Pension or Scheduled Plan can give rise to payment
of any amount that is not deductible under Code Section 280G.  Each Welfare,
Pension and Scheduled Plan has been maintained in compliance with its terms and
with the requirements prescribed by any and all statutes, orders, rules and
regulations, including but not limited to ERISA and the Code.

             (vi)  With respect to each Pension and Welfare Plan, all required
contributions have been timely made for the accounting periods ending prior to
the Closing Date and, for the period commencing on the first day of the current
accounting period to the Closing Date, all required contributions have been
timely made and/or shall be made or accrued prior to the Closing Date by the
Company and/or Lorvic in accordance with the terms of the Plan and prior
practice.  With respect to any of the Pension Plans, no reportable event within
the meaning of Section 4043 of





                                       15
<PAGE>   21

Title IV of ERISA has occurred, and no Pension Plan has been completely or
partially terminated.  No event described in Sections 4041, 4042, 4062, 4063 or
4064 of ERISA has occurred in connection with any Pension Plan, other than a
"reportable event" that is not subject to the provision for thirty days notice
to the Pension Benefit Guaranty Corporation.  No condition exists and no event
has occurred which could constitute grounds for termination of any Pension Plan
or Qualified Pension Plan sponsored by an ERISA Affiliate by the Pension
Benefit Guaranty Corporation.  Neither the Company, Lorvic nor any ERISA
Affiliate has incurred or will incur prior to Closing any material liability
under Title IV of ERISA arising in connection with the termination of or
partial withdrawal from any Qualified Pension Plan covered or previously
covered by Title VI of ERISA.  With respect to the Pension and Welfare Plans,
there have been no prohibited transactions as defined in Section 406 of Title I
of ERISA or Code Section 4975.  With respect to the Pension, Welfare, Scheduled
Plans and Qualified Pension Plans sponsored by an ERISA Affiliate, no claims
with respect to the assets thereof (other than routine claims for benefits), or
the assets of the Company, Lorvic or an ERISA Affiliate are pending or
threatened, and the Company, Lorvic or any ERISA Affiliate has knowledge of any
facts which would give rise to or could reasonably be expected to give rise to
any such claims and neither the Company, Lorvic nor an ERISA Affiliate nor any
of their directors, officers, employees or any other "fiduciary", as such term
is defined in Section 3(21) of ERISA, has any liability for failure to comply
with ERISA, the Code or any other law for any action or failure to act in
connection with the administration or investment of such Plan.  Each Welfare
Plan may be terminated after Closing to eliminate the liability for claims
incurred after Closing.  The most recent financial statement of the Company,
Lorvic and each ERISA Affiliate recognizes, in accordance with generally
accepted accounting principles and statement of Financial Accounting Standards
No. 106, material liabilities under the Welfare and Scheduled Plans that are
not insured by fully paid, nonassessable insurance policies and to the best of
the Company's and Lorvic's knowledge, and the knowledge of any ERISA Affiliate,
there are no other such material liabilities.  Any contribution made or accrued
with respect to any Pension, Welfare or Scheduled Plan is fully deductible for
Federal income tax purposes by the Company and/or Lorvic.

             (vii)  With respect to each Plan listed on Schedule 3.1(l), the
Company and/or Lorvic has furnished to Purchaser true and complete copies of
(aa) the Plan documents, (bb) the most recent determination letters received
from the Internal Revenue Service, (cc) Form 5500 Annual Report (including all
schedules) for the three most recent Plan years, (dd) the actuarial and audited
financial reports for the three most recent Plan years, (ee) all related trust
agreements, insurance contracts or other funding agreements, insurance
contracts or other funding agreements which implement such Plan and (ff) a copy
of each and any general explanation or communication which was required to be
distributed or otherwise provided to





                                       16
<PAGE>   22

participants in such Plan which describes all or any relevant aspect of each
Plan listed in Schedule 3.1(l), including any summary plan description, summary
annual report and/or summary of material modifications, (gg) a description of
any unwritten Plan listed on Schedule 3.1(l) as comprehended or maintained by
the Company, Lorvic and/or any ERISA Affiliate to the Closing or to which the
Company, Lorvic and/or an ERISA Affiliate contributes, including a description
of eligibility or other relevant aspects of the obligation, and (hh) a copy of
any and all rulings or notices, other than Internal Revenue Service
determination letters, issued by any governmental agency with respect to the
Plans.

             (viii)  None of the transactions contemplated by this Agreement is
a "prohibited transaction", as such term is defined in Section 406 of Title I
of ERISA or in Code Section 4975 or adversely affects the qualified status of
the Pension Plans under Code Section 401(a).

             (ix)  The Company, Lorvic and/or any ERISA Affiliate has not
incurred any liability to the Pension Benefit Guaranty Corporation, the
Internal Revenue Service and/or the Department of Labor with respect to any
Qualified Pension Plan, Employee Benefit Welfare Plan or Non- Qualified Pension
Plan that has not been satisfied in full and no condition exists which presents
a material risk to the Company or Lorvic of incurring such liability.

             (x)  With respect to the Scheduled Plans, all required or
recommended payments, premiums, contributions, reimbursements or accruals for
all periods ending prior to or as of the Closing (including periods from the
first day of the then current plan year to the Closing) shall have been made or
properly accrued on the Closing Balance Sheet.  None of the Scheduled Plans has
any unfunded liabilities which are not reflected on the Closing Balance Sheet.
Any contribution made or accrued with respect to any Pension Plan, Welfare Plan
or Scheduled Plan is fully deductible by the Company and/or Lorvic.

             (xi)  No employee of the Company, Lorvic or any ERISA Affiliate
will become entitled to any retirement, severance or similar benefit or
enhanced benefit solely as a result of the transaction contemplated herein.

             (xii)  There has been no amendment to, written interpretation or
announcement (whether or not written) by the Company, Lorvic or any ERISA
Affiliate relating to, or change in employee participation or coverage under
any Welfare, Pension or Scheduled Plan which would increase materially the
expense of maintaining such Plan above the level of expense incurred in respect
thereof for the fiscal year ending March 31, 1994.

any Governmental Authority, in each case applicable to the Purchaser or its
assets or (iii) conflict with or result in a default or breach of any provision
of any material contract or agreement to which the Purchaser is a party or by
which its assets may be bound.  No material filing with, and no material
permit, authorization, consent or approval of, any Person is necessary for the
consummation by the Purchaser of the transactions contemplated by this
Agreement and the Documents.  For purposes of making the representation set
forth in clause (ii) and in the fifth sentence of this subsection (a), the
Purchaser has assumed and, with the Company's permission, relied on the
representation made by the Company in Section 3.1(b) hereof that the total
assets and annual net sales of the ultimate parent entity, if any, of the
Company are less than $100,000,000.  The total assets and annual net sales of
the ultimate parent entity of the Purchaser are less than $100,000,000.

         (b) BROKERS.  No agent, broker, investment banker, or other Person
acting on behalf of the Purchaser or under the authority of the Purchaser is or
will be entitled to any fee or commission directly or indirectly from the
Stockholders (or the Company or Lorvic in the event the transactions
contemplated

hereby.

         (c) INVESTMENT INTENT.  The Purchaser acknowledges that the Shares
have not been registered under the Securities Act of 1933, as amended (the
"Securities Act"), and that the Shares may not be resold absent such
registration or unless an exemption therefrom is available.  The Purchaser is
acquiring the Shares for its own account, for investment purposes only and not
with a view toward distribution thereof.  The Purchaser qualifies as an
"accredited investor", as such term is defined in Rule 501(a) promulgated
pursuant to the Securities Act.

                                   ARTICLE V

                                INDEMNIFICATION

    5.1.     SURVIVAL.  The representations and warranties set forth in this
Agreement shall survive for two (2) years following the Closing Date; provided
that any claims for which the party asserting such claim shall have given
proper notice in accordance with the terms of this Agreement (and the Escrow
Agreement) on or prior to the expiration of such period shall survive until
such claim is resolved pursuant to the terms of this Agreement or the Escrow
Agreement.

    5.2.     INDEMNIFICATION.  (a) Pursuant to the terms of the Escrow
Agreement and subject to the conditions set forth in this Section 5.2,
subsequent to the Closing Date the Purchaser (including, for purposes of this
Article V, any Person which, after the Closing Date, is an Affiliate of the
Purchaser), shall be indemnified and held harmless by the Stockholders against
any liability (whether fixed or unfixed, liquidated or unliquidated), loss,
cost, actual or punitive damage, deficiency, demand, claim, suit, action or
cause of action, fine, penalty, cost or expense of any and all investigation or
proceeding, settlement, compromise (including reasonable attorney's fees and
costs) (collectively, "Losses" and individually, a "Loss") which any such
Person may suffer, sustain or become subject to by virtue of or which arise out
of, or result from, (i) any breach of the covenants, representations and
warranties of the Company or the Stockholders set forth in this Agreement and
(ii) the Tax Claim; provided that:

             (A) the Purchaser's right to indemnification for Losses arising
         pursuant to clause (i) of this Section 5.2(a) shall be satisfied only
         by recourse to the funds deposited and remaining in the General Escrow
         Account;

             (B) the Purchaser's right to indemnification for Losses arising
         pursuant to clause (ii) of this Section 5.2(a) shall be the
         Purchasers' only remedy for Losses





                                       27
<PAGE>   33

    incurred in connection with the Tax Claim and shall be satisfied only by
    recourse to the funds deposited and remaining in the Tax Claim Escrow
    Account; provided, however, that any payment for a Loss involving interest
    and penalties, if any, on the Tax Claim to be made prior to June 30, 1996
    in connection with the Tax Claim to the extent such interest and penalties
    exceed the Tax Claim Escrow Account may be satisfied, by recourse to the
    General Escrow Account up to the lesser of (x) $200,000 and (y) the total
    amount of interest and penalties included in such Losses;

             (C) the Stockholders shall not have any personal liability to the
    Purchaser with respect to any Losses arising out of clauses (i) and
    (ii) of this Section 5.2(a);

             (D) notwithstanding anything to the contrary contained herein, the
    Purchaser shall not be entitled to indemnification hereunder for any
    Loss arising out of an indemnified matter referred to in the
    Contingent Payment Agreement dated as of the Closing Date between the
    Purchaser and Nemanick, and Purchaser's sole remedy with respect to
    any such Loss will be pursuant to the Contingent Payment Agreement
    between Purchaser and Nemanick;

             (E) notwithstanding anything to the contrary contained herein, the
    Purchaser shall not be entitled to indemnification hereunder for any
    Loss arising from a breach of any representation or warranty set forth
    herein and the amount of any Loss incurred in respect of such breach
    shall not be included in the calculation of aggregate Losses for
    purposes of clause (G) of this Section 5.2(a), to the extent that a
    liability arising as a result of such breach is disclosed or reflected
    on the Closing Balance Sheet as a current liability and included in
    the calculation of Net Working Capital.

             (F) the Purchaser shall not be entitled to indemnification with
    respect to any individual Loss unless such Loss exceeds $5,000
    (provided that where more than one Loss relates directly or indirectly
    to the same cause or event or related group of events, for purposes of
    this clause (F) such Losses shall be treated as one Loss); and

             (G) the Purchaser shall not be entitled to indemnification with
    respect to any individual Loss in excess of $5,000 until all such
    Losses exceed, in the aggregate, $50,000, in which case the Purchaser
    will be entitled to indemnification only to the extent such Losses
    exceed $50,000.

Notwithstanding anything to the contrary contained herein, Losses arising out
of or from any breach of the representation and





                                       28
<PAGE>   34

warranty contained in Sections 3.1(r) and 3.1(s) shall not (i) be subject to
the provisions of clauses 5.2(a)(F) and 5.2(a)(G) or (ii) be included in the
calculation of the aggregate Losses for purposes of clause (G) of this Section
5.2(a).

         (b) Subject to the conditions set forth in this Section 5.2,
subsequent to the Closing Date the Purchaser shall indemnify each Stockholder
and his or its estate, heirs, personal representatives or successors and hold
him or it harmless against any Loss which any such Person may suffer, sustain
or become subject to as a result of any breach by the Purchaser of its
covenants, representations and warranties set forth herein.

         (c) No Person shall be liable for any claim for indemnification under
subsections (a) or (b) above unless written notice of a claim for
indemnification is delivered by the Person seeking indemnification to the
Person from whom indemnification is sought (i) at any time with respect to
breaches of covenants required to be performed subsequent to the Closing or the
Tax Claim or (ii) prior to two (2) years from the Closing Date with respect to
all other claims.  All notices given in this subsection (c) shall set forth
with reasonable specificity the basis for the claim for indemnification and, in
the case of claims for which indemnification is sought against any Escrow
Account, notice shall be given to all of the Stockholders.

         (d) Promptly after the assertion by any third party of any claim,
demand or notice (a "Third Party Claim") against any Person entitled to
indemnification under this Section 5.2 ("Indemnitee") that results or may
result in the incurrence by such Indemnitee of any Loss for which such
Indemnitee would be entitled to indemnification pursuant to this Agreement,
such Indemnitee shall promptly notify the parties from whom such
indemnification could be sought (the "Indemnitors") of such Third Party Claim.
In the case of claims for which indemnification is sought against any Escrow
Account, notice shall be given to the Stockholders.  In the case of claims for
which indemnification is sought against the Contingent Payment Fund, notice
shall be given to Nemanick.  Thereupon, the Indemnitors shall have the right,
upon written notice (the "Defense Notice") to the Indemnitees within 30 days
after receipt by the Indemnitors of notice of the Third Party Claim (or sooner
if such claim so requires) to conduct, at their own expense, the defense
against the Third Party Claim in their own names or, if necessary, in the names
of the Indemnitees.  The Defense Notice shall specify the counsel the
Indemnitors shall appoint to defend such Third Party Claim (the "Defense
Counsel") and the Indemnitees shall have the right to approve the Defense
Counsel, which approval shall not be unreasonably withheld.  In the event the
Indemnitees and the Indemnitors cannot agree on such counsel within 10 days
after the Defense Notice is given, then the Indemnitors shall propose an
alternate Defense Counsel, which shall be subject again to the Indemnitees'
approval.  Any Indemnitee shall have the right to employ separate counsel in
any such Third Party Claim and/or to participate in the defense thereof, but
the fees and expenses of such counsel shall not be included as part of any Loss
incurred





                                       29
<PAGE>   35

by the Indemnitee unless (i) the Indemnitors shall have failed to give the
Defense Notice within the prescribed period, (ii) such Indemnitee shall have
received an opinion of counsel, reasonably acceptable to the Indemnitors, to
the effect that the interests of the Indemnitee and the Indemnitors with
respect to the Third Party Claim are sufficiently adverse to prohibit the
representation by the same counsel of both parties under applicable ethical
rules, or (iii) the employment of such counsel has been specifically authorized
by the Indemnitors.  The party or parties conducting the defense of any Third
Party Claim shall keep the other parties apprised of all significant
developments and shall not enter into any settlement, compromise or consent to
judgment with respect to such Third Party Claim unless the Purchaser and the
Stockholders consent, such consent not to be unreasonably withheld.  In the
event that the Indemnitors shall fail to give a Defense Notice within such 30-
day period, they shall be deemed to have elected not to conduct the defense of
the subject claim.  A failure by an Indemnitee to give timely, complete or
accurate notice as provided in subsection (c) or this subsection (d) will not
affect the rights or obligations of any party hereunder except and only to the
extent that, as a result of such failure, any party entitled to receive such
notice was deprived of its right to recover any payment under its applicable
insurance coverage or was otherwise damaged or prejudiced as a result of such
failure to give timely notice.

         (e) The amount of any Loss subject to indemnification under Section
5.2(a) shall be calculated net of any amounts which have been previously
recovered by the Purchaser under insurance policies or other collateral sources
(such as contractual indemnities of any Person which are contained outside this
Agreement), and the Purchaser hereby covenants that it will not release any
such collateral sources from any obligations they may have.  In the event any
such amounts recovered under insurance policies or other collateral sources are
not received before any claim for indemnification is paid pursuant to this
Section 5.2, then the Purchaser shall pursue such insurance policies or
collateral sources with reasonable diligence, and in the event it receives any
recovery, the amount of such recovery shall be applied first, to reimburse the
Purchaser for its out-of-pocket expenses (including attorneys' fees) expended
in pursuing such recovery, second, to refund any payments made by any Escrow
Account which would not have been so paid had such recovery been obtained prior
to such payment, and third, any excess to the Purchaser.  If the Purchaser
fails to pursue any such insurance policies or collateral sources with
reasonable diligence, then, without prejudice to any rights the Stockholders
may have against the Purchaser because of such failure, the Stockholders shall
have the right of subrogation to pursue such insurance policies or collateral
sources and may take any reasonable actions necessary to pursue such rights of
subrogation in its name or the name of the party from whom subrogation is
obtained.  The Purchaser shall reasonably cooperate with the Stockholders to
pursue a subrogation claim.  Any recovery obtained by the Stockholders shall be
applied first, to reimburse the Stockholders for their out-of-pocket expenses
(including





                                       30
<PAGE>   36

attorney's fees) expended in pursuing such recovery, second, to refund to the
Stockholders any payments made by any Escrow Account pursuant to Section 5.2
hereof with respect to the Losses for which the collateral source was also
responsible, and third, any excess to the Purchaser.  In addition, all Losses
subject to indemnification hereunder shall be calculated net of any tax
benefits which have been realized by the Purchaser as a result thereof plus the
net present value (using a discount factor equal to the short-term Applicable
Federal Rate then in effect and assuming the income tax rates then in effect
for any given period remain unchanged) of tax benefits which will be realized
by the Purchaser or any Affiliate in subsequent tax years.  Purchaser and
Stockholders agree to treat any payment hereunder to Purchaser as an adjustment
to the Purchase Price.  However, in the event the Internal Revenue Service
determines that any such payment constitutes taxable gain or income to
Purchaser, such payment shall be increased so that the Purchaser receives, on
an after-tax basis, the amount which would have been received had the payment
not resulted in taxable gain or income.

    5.3.     LIMITATION OF RECOURSE.  The rights of the parties for
indemnification relating to this Agreement or the transactions contemplated
hereby shall be strictly limited to those contained in Section 5.2 hereof, and
subject to the last sentence hereof, such indemnification rights shall be the
exclusive remedies of the parties subsequent to the Closing Date with respect
to any matter in any way relating to this Agreement or arising in connection
herewith.  To the maximum extent permitted by law, the Purchaser and the
Company hereby waive and shall cause their Affiliates to waive all other rights
and remedies with respect to any such matter, whether under any Laws
(including, without limitation any right or remedy under CERCLA or any other
Environmental Law), at common law or otherwise.  Except as provided in, and in
accordance with, Section 5.2(a), no claim, action or remedy shall be brought or
maintained by the Purchaser or the Company or their respective Affiliates,
successors or permitted assigns against the Stockholders, and no recourse shall
be brought or granted against any of them, by virtue of or based upon any
alleged misstatement or omission respecting an inaccuracy in or breach of any
of the representations, warranties or covenants of the Company set forth or
contained in this Agreement, except to the extent that the same shall have been
the result of fraud by any such Person (and in the event of fraud, recourse
shall only extend to those Persons committing fraud).

    5.4.     EXCULPATION, ETC.  The Company and Lorvic hereby exculpate (to the
greatest extent permitted by applicable law) and shall indemnify, defend and
hold harmless, each of the directors and officers of the Company and Lorvic
against all Losses arising out of any violations or alleged violations of
fiduciary duties of care or loyalty to the Company or Lorvic in their
capacities as officers or directors of the Company occurring at or prior to the
Closing Date to the fullest extent permitted under Delaware law.

    5.5.     SPECIAL PROVISIONS RELATING TO TAX MATTERS.

         (a) TAX CLAIM.  The term "Tax Claim" means the net amount of Taxes
assessed against the Company and Lorvic as a result of the disallowance in
whole or part of deductions taken or to be taken for tax periods ending on or
before the Closing Date by the Company or Lorvic in connection with the Asset
Purchase Agreement dated as of December 28, 1989, by and among LC Acquisition
Corporation, The Lorvic Corporation, Semicon, Inc., The Lorvic International
Ltd. and R.P. Scherer Corporation for the amortization of a noncompete
agreement and secrecy agreement in a total amount of $3,000,000.  The
Stockholders have given the Purchaser notice of the Tax Claim.

         (b) TAX PROCEEDINGS.  Notwithstanding anything to the contrary
contained in Article V hereof, the Stockholders shall exercise, at their
expense, control over the handling, disposition, and settlement of any
governmental inquiry, examination, or proceeding that could result in a
determination with respect to the Tax Claim (each a "Tax Claim Proceeding").
The Purchaser shall take all actions reasonably requested by the Stockholders
in connection with any Tax Claim Proceeding, including, but not limited to, the
execution and delivery of power(s) of attorney, certificates of officers or
other instruments required in connection therewith.  The Stockholders shall,
however, promptly notify the Purchaser if, in connection with any such inquiry,
examination, or proceeding any governmental authority proposes to make any
assessment or adjustment, which would have an adverse impact on the Company or
Lorvic for tax periods beginning after the Closing Date, and shall consult with
the Purchaser with respect to any such proposed assessment or adjustment.
Purchaser shall notify Stockholders promptly upon learning of such inquiry,
examination or proceeding.  Notwithstanding anything to the contrary contained
in Article V hereof, and notwithstanding the foregoing, the Stockholders shall
not enter into any settlement, compromise or consent to judgment with respect
to the Tax Claim if such settlement, compromise or consent to judgment would be
for an amount exceeding the funds in the Tax Claim Escrow Account, plus, if
such settlement occurs on or prior to June 30, 1996, $200,000, without the
consent of Purchaser, which consent shall not be unreasonably withheld.


                                   ARTICLE VI

                     TREATMENT OF RECEIVABLES AND INVENTORY

    6.1.     SPECIAL PROVISIONS RELATING TO CLOSING DATE RECEIVABLES AND
INVENTORY.

         (a) The Purchaser shall use its reasonable best efforts in accordance
with the Purchaser's normal practices in collecting its own accounts receivable
to collect the Closing Date Receivables.  Any payments received by the
Purchaser, the Company, Lorvic or their respective affiliates from any account





                                       32
<PAGE>   38

debtor subsequent to the Closing Date shall, unless specifically allocated by
such account debtor to a specific receivable, be credited against the oldest
Closing Date Receivable or portion thereof of such account debtor.

         (b) If the Purchaser makes a claim for indemnification under Section
5.2 for a breach of the representations set forth in Sections 3.1(r) and 3.1(s)
and such claim is paid out of the General Escrow Account or otherwise, then the
Purchaser shall cause the Company or Lorvic, as the case may be, to execute and
deliver to the Stockholders, such bills of sale and other instruments of
transfer, conveyance and assignment as shall be reasonably necessary to
transfer, convey and assign any Closing Date Receivables and/or inventory for
which the Purchaser has been reimbursed pursuant to Section 5.2 hereof, to the
Stockholders.


                                  ARTICLE VII

                                 MISCELLANEOUS

    7.1.     AGREEMENTS RELATING TO TAX REFUNDS.  (a)  The Stockholders shall,
at their expense, prepare all income tax returns for periods ending on or prior
to the Closing Date and any amendments to such returns (the "Stockholder
Returns").  The Stockholder Returns shall be prepared on a basis consistent
with the Company's prior practices in preparing returns, and will be delivered
to the Purchaser at least seven days prior to the due dates, without extension,
unless the Company has not afforded the Stockholders timely access to the
information necessary to prepare such returns.  In connection therewith, the
Company shall afford the Stockholders or their representative reasonable access
to the books and records of the Company necessary to prepare such Stockholder
Returns.  After the Purchaser has had an opportunity to review the Stockholder
Returns, the Purchaser shall cause the Company to timely file the Stockholder
Returns as prepared by the Stockholders, take all actions reasonably requested
by the Stockholders in connection with the filing of any Stockholder Returns
and take such other reasonable steps as are necessary or appropriate to assist
the Stockholders in obtaining any Tax Refunds.  Subject to the following
sentence, the Stockholders shall exercise control over the handling,
disposition, and settlement of any governmental inquiry, examination, or
proceeding relating to or arising out of the Nemanick Option and/or the
Nemanick Bonus (each, a "Stockholder Tax Proceeding").  Notwithstanding
anything to the contrary contained in Article V hereof, the Stockholders shall
keep the Purchaser apprised of all significant developments and shall not enter
into any settlement, compromise or consent to judgment with respect to any
Stockholder Tax Proceedings, if such settlement, compromise or consent to
judgment would have an adverse impact on the Company with respect to tax
periods beginning after the Closing Date, without the consent of the Company,
which consent will not be unreasonably withheld.  It is the intent of the
parties hereto that the taxable year of the Company and Lorvic will close for
Federal





                                       33
<PAGE>   39

income tax purposes at the close of business on the Closing Date (the "Stub
Year") and that any net operating losses generated in the Stub Year will be
carried back to prior taxable years.  Neither the Company nor the Purchaser
shall take any action that would be inconsistent with the intent expressed in
the preceding sentence.

         (b) Promptly upon receipt of any Tax Refunds, the Purchaser shall
cause the Company to pay the amount of all such Tax Refunds, along with the
excess of any interest actually received by the Company in connection therewith
over the amount of any taxes the Company owes with respect to the receipt of
such interest, as follows:  (x) to the Escrow Agent an amount to be deposited
into the General Escrow Account up to the amount (if any) distributed to the
Purchaser from the General Escrow Account pursuant to Section 1.4(c)(ii)
hereof, and (y) the balance to the Stockholders, pro rata in accordance with
their Percentage Interests, as an adjustment to the purchase price.

         (c) If (x) all or any portion of the loss, deduction or credit
generated by the Company or Lorvic in connection with (i) the exercise of the
Nemanick Option and/or (ii) the Nemanick Bonus, in either case does not
generate a Tax Refund, but instead is applied against or otherwise reduces a
liability (a "Tax Liability") for any taxes (including without limitation
Taxes) of the Company or Lorvic or (y) any Tax Refund generated is applied
against or otherwise reduces a Tax Liability of the Company or Lorvic (the
amount so applied or resulting in such reduction in any such case being
referred to as the "Tax Reduction Amount"), then (A) the parties hereto shall
execute Mutual Written Instructions (as defined in the Escrow Agreement)
instructing the Escrow Agent to release to the Stockholders, from the Tax Claim
Escrow Account if the Tax Reduction Amount relates to the Tax Claim or from the
General Escrow Account if the Tax Reduction Amount relates to a Tax Liability
other than the Tax Claim which would result in a Loss under Section 5.2 hereof,
not later than the date such other Tax Liability would otherwise be due and
payable without extension, an amount equal to the Tax Reduction Amount less an
amount (if any) equal to the amount disbursed to Purchaser from the General
Escrow Account pursuant to Section 1.4(c)(ii) hereof and (B) if the Tax
Reduction Amount reduces or is otherwise applied to a Tax Liability which would
not result in a Loss under Section 5.2 hereof, the Purchaser shall pay to the
Stockholders, pro rata in accordance with their Percentage Interests, the
amount of such Tax Reduction Amount.  If the portion of the Tax Reduction
Amount distributable to the Stockholders hereunder exceeds the balance in the
Tax Claim Escrow Account or the General Escrow Account, as appropriate, then
the Purchaser shall pay to the Stockholders, not later than such date, the
amount of such excess.

    (d)  Neither the Company, the Purchaser nor any Affiliate thereof shall
request under Section 301.6501(d) of the Treasury Department Regulations or any
similar statutory provision or regulation the prompt assessment by any taxing
authority of any





                                       34
<PAGE>   40

taxes (including without limitation Taxes), for which the Company may be
liable.

    7.2.     PLAN EXPENSE REIMBURSEMENT.  The Purchaser shall consult with
Nemanick on all Plan Expenses (as defined below) to be incurred by the
Purchaser.  Purchaser shall have the right to reimbursement from the General
Escrow Account of an aggregate amount not to exceed $20,000 for all legal
expenses, accounting fees, taxes, penalties and government user fees paid by
Purchaser to correct the allocation of contributions under the Lorvic Profit
Sharing Plan to comply with the 1986 Tax Reform Act and to bring the Lorvic
Pension Plan into compliance with Federal legislation (collectively, "Plan
Expenses").

    7.3.     INTERPRETIVE PROVISIONS; CERTAIN DEFINITIONS.  Whenever used in
this Agreement, "to the Company's knowledge" or "to the knowledge of the
Company" shall mean the actual knowledge of those Persons who are listed on
Exhibit H and "to Purchaser's knowledge" or "to the knowledge of Purchaser"
shall mean the actual knowledge of the Persons listed on Exhibit G.  The
inclusion of any information on any schedule shall not be deemed to be an
admission or acknowledgement by the Company, in and of itself, that such
information is required to be listed on such schedule or is material to or
outside the ordinary course of the business of the Company and Lorvic.  Any
disclosure made in any Schedule to this Agreement which should, based on the
substance of such disclosure, be applicable to another Schedule to this
Agreement shall be deemed to be made with respect to such other Schedule
regardless of whether or not a specific reference is made thereto.

    7.4.     NO ADDITIONAL REPRESENTATIONS.  THE PURCHASER AND ITS
REPRESENTATIVES HAVE UNDERTAKEN AN INDEPENDENT INVESTIGATION AND VERIFICATION
OF THE BUSINESS, OPERATIONS AND FINANCIAL CONDITION OF THE COMPANY AND LORVIC.
THE PURCHASER EXPRESSLY ACKNOWLEDGES AND AGREES THAT IT IS NOT RELYING ON THE
COMPANY, LORVIC OR THE STOCKHOLDERS WITH RESPECT TO ANY MATTER IN CONNECTION
WITH THE PURCHASER'S INVESTIGATION OR EVALUATION OF THE COMPANY OR LORVIC,
(INCLUDING ANY OF THEIR ASSETS) EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES
EXPRESSLY SET FORTH IN SECTION 3 OF THIS AGREEMENT.  THE PURCHASER EXPRESSLY
ACKNOWLEDGES AND AGREES THAT EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT,
THE CONDITION OF THE BUSINESS OF THE COMPANY AND LORVIC, INCLUDING THE ASSETS
OF THE COMPANY OR LORVIC, SHALL BE "AS IS" AND "WHERE IS".

    7.5.     ACTION BY STOCKHOLDERS.  All action required to be taken by the
Stockholders under this Agreement, the Documents and the Escrow Agreement
(including, without limitation, the giving and receiving of all notices,
consents and waivers and the execution and delivery of any documents, including
any amendments to the Escrow Agreement, and the execution and delivery of any
agreements and releases in connection with the settlement of any dispute or
claim under Article I or V hereof or the Escrow Agreement) shall be sufficient
if taken on the authority or with the written consent of the Stockholders
holding a majority of the common stock on the Valuation Date.

    7.6.     APPOINTMENT OF AGENT.  (a) By their execution and delivery hereof,
(i) each Stockholder other than CVCA, Leck, Kirtley, Brian J.  Richmand and
Richard L. Perkal (such other Stockholders being the "Nemanick Stockholders")
shall be deemed, for themselves and their personal representatives and other
successors, to have constituted and appointed, effective from and after the
Closing Date, Nemanick as their agent and attorney-in-fact, to take all action
required or permitted to be taken by the Nemanick Stockholders under this
Agreement, the Documents and the Escrow Agreement (including, without
limitation, the execution and delivery of the Escrow Agreement the giving and
receiving of all notices, consents and waivers and the execution and delivery
of all documents, including any amendments of the Escrow Agreement, and the
execution and delivery of any agreements and releases in connection with the
settlement of any dispute or claim under Article I or V hereof or the Escrow
Agreement).

         (b) Nemanick, as Agent for the Nemanick Stockholders shall be entitled
to rely, and shall be fully protected in relying, upon any statements furnished
to him by any Nemanick Stockholder, the Company, Lorvic or the Purchaser, or
any other evidence deemed by Nemanick to be reliable, and Nemanick shall be
entitled to act on the advice of counsel selected by him.  Nemanick shall not
be responsible for the genuineness or validity of any document and shall have
no liability for acting in accordance with any written instructions given to
him and believed by him to be signed by the proper parties.  Nemanick shall be
fully justified in failing or refusing to take any action under this Agreement
unless he shall have been expressly indemnified to his satisfaction by the
Nemanick Stockholders severally according to their respective Percentage
Interests against any and all liability and expense that Nemanick may incur by
reason of taking or continuing to take any such action.  Nemanick shall in all
cases be fully protected in acting, or refraining from acting, under this
Agreement in accordance with a request of the Nemanick Stockholders, and any
action taken or the failure to act pursuant thereto, shall be binding upon all
of the Nemanick Stockholders.

         (c) Nemanick shall be entitled to retain counsel, accountants and
other advisors and to incur such expenses (including litigation expenses) as
Nemanick deems to be necessary or appropriate in connection with his
performance of his obligations under this Agreement, and all such fees and
expenses (including reasonable attorney's fees) incurred by Nemanick shall be
paid by the Nemanick Stockholders pro rata according to their respective
Percentage Interests.

         (d) The Nemanick Stockholders hereby agree severally to indemnify
Nemanick (in his capacity as Agent), ratably according to their respective
Percentage Interests against, and to hold Nemanick (in his capacity as Agent)
harmless from, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of
whatever kind which may at any time be imposed upon, incurred by or asserted
against Nemanick in any way relating to or arising





                                       36
<PAGE>   42

out of his action or failure to take action pursuant to this Agreement in his
capacity as Agent; provided, that no Nemanick Stockholder shall be liable for
the payment of any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the gross negligence or willful misconduct of Nemanick.

         (E) AMENDMENTS; SURVIVAL.  No provision of this Section 7.6 may be
amended without the consent of Nemanick.  The agreements in this Section 7.6
shall survive termination of this Agreement.

    7.7.     EXPENSES.  Except as otherwise provided in this Agreement, all
legal and other costs and expenses incurred in connection with this Agreement
and the other Documents and the transactions contemplated hereby and thereby
shall be paid by the parties incurring such expenses.

    7.8.     ENTIRE AGREEMENT; AMENDMENT.  (a) This Agreement and the Exhibits
and Schedules attached hereto contain the entire agreement among the parties
with respect to the transactions contemplated hereby and supersede all prior
agreements and understandings among the parties with respect thereto,
including, without limitation, the Letter of Intent dated March 2, 1995,
between the Stockholders, the Company and the Purchaser.

         (b) This Agreement shall not be altered or otherwise amended except
pursuant to an instrument in writing signed by the parties hereto.

    7.9.     SEVERABILITY.  It is the desire and intent of the parties hereto
that the provisions of this Agreement be enforced to the fullest extent
permissible under the laws and public policies applied in each jurisdiction in
which enforcement is sought.  Accordingly, if any particular provision of this
Agreement shall be adjudicated by a court of competent jurisdiction to be
invalid, prohibited or unenforceable for any reason, such provision, as to such
jurisdiction, shall be ineffective, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of
such provision in any other jurisdiction.  Notwithstanding the foregoing, if
such provision could be more narrowly drawn so as not to be invalid, prohibited
or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so
narrowly drawn, without invalidating the remaining provisions of this Agreement
or affecting the validity or enforceability of such provision in any other
jurisdiction.

    7.10. DESCRIPTIVE HEADINGS; NUMBER AND GENDER.

         (a) Descriptive headings are for convenience only and shall not

without the consent of the Stockholders, provided, however that the Purchaser
may collaterally assign this Agreement, without the consent of the
Stockholders, to a financial or lending institution providing financing to the
Purchaser; provided, further, that no such assignment shall release the
Purchaser from his obligations hereunder.

    7.16.  CONSTRUCTION.  The provisions of this Agreement shall be construed
according to their fair meaning and neither for nor against any party hereto
irrespective of which party caused such provisions to be drafted.  Each of the

                                ESCROW AGREEMENT


         ESCROW AGREEMENT made May 4, 1995 (the "Agreement"), among YOUNG
DENTAL MANUFACTURING COMPANY, a Missouri corporation ("Buyer"), CHEMICAL
VENTURE CAPITAL ASSOCIATES, A California Limited Partnership ("CVCA"), P.
JEFFREY LECK ("Leck"), JOHN F. KIRTLEY ("Kirtley"), RICHARD C. NEMANICK
("Nemanick"), the other stockholders executing a signature page hereto (each, a
"Stockholder" and together with CVCA, Leck, Kirtley and Nemanick, the
"Stockholders"), and LORVIC HOLDINGS, INC., a Delaware corporation ("Lorvic")
(collectively, "Sellers"), and BOATMEN'S TRUST COMPANY (the "Escrow Agent").

         WHEREAS, Buyer and Sellers are parties to a certain Stock Purchase
Agreement made as of May 4, 1995 (the "Purchase Agreement"), pursuant to which
Buyer is purchasing all of the capital stock of Lorvic;

         WHEREAS, pursuant to the Purchase Agreement, Buyer is required to
deposit with the Escrow Agent a portion of the consideration payable to
Sellers; and

         WHEREAS, the Escrow Agent has accepted such agency and agreed to hold
such funds in accordance with and subject to the terms of this Agreement.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties hereto agree as follows:

         1.  Establishment of Escrow Accounts.  The Escrow Agent shall  
establish at its offices located at St. Louis, Missouri three escrow accounts
(each an "Escrow Account" and collectively the "Escrow Accounts") and shall
cause all funds deposited into the Escrow Accounts to be held, invested and
distributed in accordance with the terms of this Agreement.  The amounts
deposited into the Escrow Accounts, together with any proceeds of investments
thereof, that may be held in the Escrow Accounts from time to time are
hereinafter referred to collectively as "Escrow Funds."  The Escrow Agent shall
keep appropriate records to reflect the current value from time to time of the
Escrow Funds, including appropriate adjustments for disbursements and income
earned or losses in respect thereof.

         2.  Delivery of Escrow Funds.  Buyer hereby agrees to deliver or
cause to be delivered to the Escrow Agent in accordance with the terms of
the Purchase Agreement, cash in the following amounts:

                 (a)      $100,000 into an Escrow Account to be known as the
         "Purchase Price Adjustment Escrow Account".





<PAGE>   2

                 (b)      $700,000 into an Escrow Account to be known as the
        "Tax Claim Escrow Account".
        
                 (c)      $1,050,000 into an Escrow Account to be known as the
        "General Escrow Account".

        3.  Investment of Escrow Funds.  The Escrow Funds shall be invested
and reinvested by the Escrow Agent in such amounts and in such manner
as Sellers and Buyer shall instruct the Escrow Agent from time to time in
writing; provided, however, that after the second anniversary hereof, the
Escrow Agent shall invest the Escrow Funds in any investment which is exempt
from federal, state and local tax as directed by the Sellers.  Initially, the
Escrow Funds shall be invested by the Escrow Agent in accordance with the
instructions set forth on Exhibit A hereto.  If the Escrow Agent has not
received instructions from the Buyer and the Sellers prior to 15 days of the
expiration of the term of any instrument in which Escrow Funds are invested,
the Escrow Agent shall invest such Escrow Funds in instruments of the same or
of a substantially similar type as the instruments set forth on Exhibit A
hereto. Except as provided above, the Escrow Agent shall not be required to
invest any funds held hereunder unless requested by Sellers and Buyer as
provided herein.

         4.  Release of Escrow Funds.  The Escrow Agent shall release the
Escrow Funds as follows:

                 (a)  Release from Purchase Price Adjustment Escrow Account.
         As soon as practicable after the completion of the calculation of the
         Purchase Price Adjustment (as defined in the Purchase Agreement), as
         provided in the Purchase Agreement, Buyer and Sellers shall execute
         and deliver to the Escrow Agent written instructions ("Mutual Written
         Instructions"), and the Escrow Agent shall promptly upon receipt
         thereof disburse the Escrow Funds in the Purchase Price Adjustment
         Escrow Account as provided in such Mutual Written Instructions, and,
         if such Mutual Written Instructions so direct, shall disburse to Buyer
         from the General Escrow Account the amount directed to be disbursed
         therefrom in such Mutual Written Instructions.  Notwithstanding the
         foregoing, the Escrow Agent shall disburse the Escrow Funds in
         accordance with any Certified Judgment Notice (as defined below) from
         the Buyer or any Seller which is not the subject of an Appeal Notice.

                 (b)      Release of Tax Claim Escrow Account.  (i) As soon as
         practicable after final resolution of the Tax Claim (as defined in the
         Purchase Agreement), as provided in the Purchase Agreement, Buyer and
         Sellers shall (x) determine the amount payable, if any, to the Buyer
         pursuant to Section 5.2 of the Purchase Agreement and (y) execute and
         deliver to the Escrow Agent Mutual Written Instructions to release the
         amount set forth in clause (x) to the Buyer and the balance





                                        -2-

         of the Escrow Funds in the Tax Claim Escrow Account, if any, to the
         Sellers, and the Escrow Agent shall promptly upon receipt thereof
         disburse the Escrow Funds in the Tax Claim Escrow Account as provided
         in such Mutual Written Instructions and, if such Mutual Written
         Instructions so direct, shall disburse to Buyer from the General
         Escrow Account the amount, if any, directed to be disbursed therefrom
         in such Mutual Written Instructions.  Notwithstanding the foregoing,
         the Escrow Agent shall disburse the Escrow Funds in accordance with
         any Certified Judgment Notice (as defined below) from the Buyer or any
         Seller which is not the subject of an Appeal Notice.

                 (ii)     If (x) all or any portion of the loss, deduction or
         credit generated by the Company or Lorvic in connection with (a) the
         exercise of the option granted to Nemanick pursuant to the Stock
         Option Agreement dated as of December 28, 1989, by and between the
         Company and Nemanick and/or (b) the bonus paid to Nemanick on May 2,
         1995, in either case does not generate a Tax Refund (as defined in the
         Purchase Agreement), but instead is applied against or otherwise
         reduces a liability (a "Tax Liability") for any taxes (including
         without limitation Taxes (as defined in the Purchase Agreement)) of
         the Company or Lorvic or (y) any Tax Refund generated is applied
         against or otherwise reduces a Tax Liability of the Company or Lorvic
         (the amount so applied or resulting in such reduction in any such case
         being referred to as the "Tax Reduction Amount"), then the parties
         hereto shall execute Mutual Written Instructions instructing the
         Escrow Agent to release to the Stockholders from the Tax Claim Escrow
         Account if the Tax Reduction Amount relates to the Tax Claim or from
         the General Escrow Account if the Tax Reduction Amount relates to a
         Tax Liability other than the Tax Claim which would result in a Loss
         under Section 5.2 of the Purchase Agreement, not later than the date
         such other Tax Liability would otherwise be due and payable without
         extension, an amount equal to the Tax Reduction Amount less an amount,
         if any, equal to the amount disbursed to the Buyer from the General
         Escrow Account pursuant to Section 4(a) hereof.  Notwithstanding
         anything to the contrary contained in this Subsection (ii) of Section
         4(b), if the Tax Reduction Amount relates to a Tax Liability which
         would not result in a Loss under Section 5.2 of the Purchase Agreement
         no release of Escrow Funds shall be made pursuant to this Subsection.

                 (c)      Release of General Escrow Account.

                          (1)     If the Mutual Written Instructions delivered
                 to the Escrow Agent pursuant to Section 4(a) so direct, the
                 Escrow Agent shall promptly upon receipt of such Written
                 Instructions disburse to Buyer from the General






                                     -3-
<PAGE>   4

                 Escrow Account the amount directed to be disbursed therefrom in
                 such Mutual Written Instructions.

                          (2)     The Escrow Agent shall, promptly upon receipt
                 of Mutual Written Instructions disburse to the Buyer an amount
                 not in excess of $20,000 to reimburse Buyer for its Plan
                 Expenses (as defined in the Purchase Agreement).

                          (3)     On June 30, 1996, the Escrow Agent shall if
                 the Tax Claim Escrow Account has not theretofore been
                 disbursed, (i) transfer the amount of $200,000 from the
                 General Escrow Account to the Tax Claim Escrow Account, and
                 (ii) disburse to Sellers from the General Escrow Account the
                 amount, if any, by which the balance in the General Escrow
                 Account exceeds the Initial Base Amount.  For purposes hereof,
                 "Initial Base Amount" means the sum of (A) $525,000 plus (B)
                 the aggregate amount as of such date of all claims subject to
                 a Buyer Claim Notice (as defined below) as to which the Escrow
                 Agent has not received Mutual Written Instructions or a
                 Certified Judgment Notice (as defined below) not the subject
                 of an Appeal Notice (as defined below), in either case
                 directing release of Escrow Funds ("Unresolved Claims").  The
                 Escrow Funds retained by the Escrow Agent in respect of the
                 amount referred to in clause (B) shall be held solely for the
                 purpose of satisfying the Unresolved Claims outstanding as of
                 June 30, 1996.

                          (4)     On the second anniversary of the Closing Date
                 (as defined in the Purchase Agreement), the Escrow Agent shall
                 disburse to Sellers from the General Escrow Account the
                 amount, if any, by which the balance in the General Escrow
                 Account exceeds the aggregate amount of all Unresolved Claims.
                 The Escrow Funds retained by the Escrow Agent shall be held
                 solely for the purpose of satisfying the Unresolved Claims
                 outstanding as of such second anniversary.

                          (5)  After June 30, 1996, each time an Unresolved
                 Claim is resolved as provided for below, the amount of such
                 Unresolved Claim shall be disbursed in accordance with the
                 Mutual Written Instructions or the Certified Judgment Notice
                 reflecting such resolution; provided, however, prior to the
                 second anniversary of the Closing Date, the balance of the
                 General Escrow Account will not be reduced below the sum of
                 (A) $525,000 plus (B) the aggregate amount of all remaining
                 Unresolved Claims asserted prior to June 30, 1996.

                          (6)  In the event the Escrow Agent has any doubt as
                 to any amount to be released to Buyer or Sellers from any of
                 the Escrow Accounts, it may request Mutual

<PAGE>   5

                 Written Instructions from Sellers and Buyer and may rely
                 thereon.  Notwithstanding the foregoing sentence, the Escrow
                 Agent shall disburse the Escrow Funds in accordance with a
                 Certified Judgment Notice which is not the subject of an
                 Appeal Notice.

                          (7)     All disbursements to Sellers hereunder shall
                 be in proportion to their percentage interests in the Escrow
                 Funds as set forth on Schedule A hereto; each such
                 disbursement shall be sent to the respective addresses of
                 Sellers set forth on Schedule A or to such other address as
                 provided to the Escrow Agent in writing by the Seller
                 receiving such disbursement.

                 (d)  Buyer Claim Notice; Disputed Amounts.  As contemplated by
         the provisions of Section 4(c), if Buyer shall have delivered to the
         Escrow Agent one or more written notices (each a "Buyer Claim Notice")
         stating that the amount or amounts of the General Escrow Account
         specified in such notice or notices should not be released to Sellers
         and should be released to Buyer because Buyer has made a claim against
         Sellers under the Purchase Agreement for such amount or amounts, the
         Escrow Agent shall not release such amount or amounts to Sellers and
         shall retain such  amount or amounts until the same are released
         pursuant to subsections (e) or (g) hereof.  Buyer shall deliver to
         Sellers a copy of each Buyer Claim Notice on or prior to the date of
         the delivery thereof to the Escrow Agent, and the Escrow Agent shall
         also deliver a copy thereof to Sellers promptly after receipt from
         Buyer.

                 (e)  Release to Buyer.  Unless the Escrow Agent shall have
         received a Seller Hold Notice as contemplated by Section 4(f) within
         30 days following receipt by the Escrow Agent of a Buyer Claim Notice,
         the Escrow Agent shall promptly thereafter release to Buyer such
         portion of the General Escrow Account as is claimed by Buyer in such
         Buyer Claim Notice.

                 (f)  Seller Hold Notice; Disputed Amounts.  If, within 30 days
         of the Escrow Agent's receipt of a Buyer Claim Notice pursuant to
         Section 4(d) above, any Seller named in Section 4(j) shall have
         delivered to the Escrow Agent written notice (a "Seller Hold Notice")
         stating that all or a portion of the General Escrow Account specified
         in such Buyer Claim Notice should not be released to Buyer, then the
         Escrow Agent shall not release such disputed amounts until the
         occurrence of one of the two events contemplated in Section 4(g)
         hereof.  Such Seller shall deliver to Buyer a copy of such Seller Hold
         Notice on or prior to the date of the delivery thereof to the Escrow
         Agent and the Escrow Agent shall also deliver a copy of such Seller
         Hold Notice to Buyer promptly after receipt thereof from such Seller.

                 (g)  Release After a Seller Hold Notice.  In the event that
         the Escrow Agent receives a Seller Hold Notice as contemplated by
         Section 4(f) hereof, that portion of the General Escrow Account that
         is in dispute as reflected in such Seller Hold Notice shall be held by
         the Escrow Agent until the occurrence of one of the following events:

                                  (1)  receipt by the Escrow Agent of Mutual
                 Written Instructions signed by Buyer and Sellers instructing
                 the Escrow Agent to release the disputed portion of the Escrow
                 Funds to such party or parties and in such amount or amounts
                 as is specified in such Mutual Written Instructions; or

                                  (2)  receipt by the Escrow Agent of a written
                 notice (a "Certified Judgment Notice") from Buyer or Sellers
                 certifying that a final nonappealable court judgment with
                 respect to the claim covered by the Buyer Claim Notice is
                 attached to such Certified Judgment Notice, in which case the
                 Escrow Agent shall distribute the disputed portion of the
                 Escrow Funds in accordance with such judgment, unless within
                 15 days of the Escrow Agent's receipt of a Certified Judgment
                 Notice, the Escrow Agent receives a written notice (an "Appeal
                 Notice") from the party not submitting such Certified Judgment
                 Notice stating that the judgment has or can and will be
                 appealed.  A party delivering a Certified Judgment Notice or
                 an Appeal Notice shall deliver to the other party hereto a
                 copy thereof on or prior to the date of delivery thereof to
                 the Escrow Agent, and the Escrow Agent shall also deliver a
                 copy of each Certified Judgment Notice or Appeal Notice to the
                 party which did not deliver the same promptly after the Escrow
                 Agent's receipt thereof.

                 (h)  Release of Accrued Interest.  Prior to the second
         anniversary of the Closing Date, the Escrow Agent shall distribute to
         Sellers within five days after the end of each calendar quarter, an
         amount equal to 40% of all amounts earned on funds in the Tax Claim
         Escrow Account and the General Escrow Account (other than earnings
         which are exempt from federal income taxes, which will be retained by
         the Escrow Agent); provided, however, that all of such disbursements
         shall be made from the General Escrow Account.  After the second
         anniversary of the Closing Date, earnings on the Escrow Funds will not
         be so disbursed, but will be added to the Escrow Funds.  All earnings
         on the Escrow Funds prior to the time they are disbursed will, for all
         purposes of this Escrow Agreement, be treated as Escrow Funds, and
         will be released according to the terms of Section 4(a), (b) or (c),
         as appropriate.

                 (i)  Security Interests in Escrow Fund.  (a)  Except as
         expressly provided herein, neither the Buyer nor the Sellers shall
         have any right, title or interest in or possession of any of the
         Escrow Accounts.  Therefore, neither the Buyer nor the Sellers shall
         have the ability to pledge, convey, hypothecate or grant a security
         interest in any of the Escrow Accounts or portion thereof unless and
         until such assets have been disbursed or are required to be disbursed,
         to such party in accordance with this Section 4.

                          (b)     Each of the Buyer and the Sellers
                 acknowledges that its interest in the Escrow Accounts is
                 merely a contingent right to payment from such Escrow
                 Accounts.  Each of the Buyer and the Sellers further
                 acknowledges that neither a voluntary or involuntary case
                 under any applicable bankruptcy, insolvency or similar law nor
                 the appointment of a receiver, trustee, custodian or similar
                 official in respect of the Buyer of any of the Sellers (any of
                 which is referred to herein as a "Bankruptcy Event") shall
                 increase its respective interest in the Escrow Accounts or
                 affect, modify, convert or otherwise change the contingent
                 nature of its respective right to payment from the Escrow
                 Accounts in accordance with the terms of this Agreement.
                 Nonetheless:

                                  (i)      if a court of competent jurisdiction
                          determines that the Buyer, upon the occurrence of a
                          Bankruptcy Event with respect to the Buyer, has an
                          interest in any Escrow Account that is greater than a
                          contingent right to payment from such Escrow Account
                          payable only in accordance with the provisions of
                          this Section 4, then the Buyer shall be deemed to
                          have granted on the date hereof to the Sellers a
                          first priority security interest in, and pledged to
                          the Sellers all of its right, title and interest in
                          such Escrow Account.  In such event, the Escrow Agent
                          shall be deemed to act as bailee on behalf of the
                          Sellers in respect of the Sellers' security interest
                          in the Buyer's rights to such Escrow Account.  The
                          Escrow Agent shall, upon receipt of indemnification
                          satisfactory to it from the Sellers for its fees and
                          expenses incurred in connection with taking such
                          actions, take all actions as may be reasonably
                          requested in writing of it by the Sellers to further
                          perfect the security interest granted by the Buyer
                          hereunder in such Escrow Account.  Such security
                          interest shall automatically be released with respect
                          to any funds properly distributed from such Escrow
                          Account pursuant to the terms of this Agreement; and

                              (ii)         if a court of competent jurisdiction
                          determines that any Seller, upon the occurrence of a
                          Bankruptcy Event with respect to such Seller, has an
                          interest in any Escrow Account that is greater than a
                          contingent right to payment from such Escrow Account
                          payable only in accordance with the provisions of
                          this Section 4, then such Seller shall be deemed to
                          have granted on the date hereof to the Buyer a first
                          priority security interest in, and pledged to the
                          Buyer all of such Seller's right, title and interest
                          in such Escrow Account.  In any such event, the
                          Escrow Agent shall be deemed to act as bailee on
                          behalf of the Buyer in respect of the Buyer's
                          security interest in such Seller's rights to such
                          Escrow Account.  The Escrow Agent shall, upon receipt
                          of indemnification satisfactory to it from the Buyer
                          for its fees and expenses incurred in connection with
                          taking such actions, take all actions as may be
                          reasonably requested in writing of it by the Buyer to
                          further perfect the security interest created by such
                          Seller hereunder in such Escrow Account.  Such
                          security interest shall automatically be released
                          with respect to any funds properly distributed from
                          such Escrow Account pursuant to the terms of this
                          Agreement.

                          (c)     The parties hereto agree and acknowledge that
                 the establishment and maintenance of the Escrow Accounts
                 hereunder are intended to constitute possession of the Escrow
                 Accounts for the purposes of perfecting the security interests
                 therein created hereunder.

                 (j)      Action by Sellers.  All action required to be taken
         by Sellers under this Agreement (including, without limitation, the
         giving of Mutual Written Instructions with Buyer, and the execution
         and delivery of any documents, including any amendments to this
         Agreement, and the execution and delivery of any other documents
         hereunder, shall be sufficient if executed in writing by Chemical
         Venture Capital Associates, P. Jeffrey Leck, John F. Kirtley and
         Richard C. Nemanick.  Notwithstanding the foregoing, a Seller Hold
         Notice shall be sufficient if executed in writing by any one of the
         Sellers listed in the preceding sentence.

         5.  Responsibility of the Escrow Agent.  The Escrow Agent accepts the
agency created by this Agreement upon the terms and conditions hereof
and undertakes to perform such duties and only such duties as are specifically
set forth herein.  No provision of this Agreement shall be construed to relieve
the Escrow

Agent from liability for its own gross negligence or willful
misconduct, except that:

                 (a)  The duties and obligations of the Escrow Agent shall be
         determined solely by the express provisions of this Agreement, and no
         implied covenants, duties or obligations shall be read into this
         Agreement against the Escrow Agent nor shall the Escrow Agent be bound
         by the provisions of any other agreements between the other parties
         hereto beyond the specific terms hereof; the Escrow Agent shall not be
         liable for any action taken, suffered or omitted by it in good faith
         and reasonably believed by it to be authorized or within the
         discretion, rights, duties, privileges or powers conferred upon it by
         this Agreement; the Escrow Agent shall not be liable for any error of
         judgment made in good faith by a responsible officer or officers of
         the Escrow Agent, unless the Escrow Agent was grossly negligent in
         ascertaining the pertinent facts or in employing such officer or
         officers; and the Escrow Agent shall not be liable to any person with
         respect to any action taken, omitted or suffered to be taken by it in
         accordance with the provisions of this Agreement or in accordance with
         the written directions of Sellers or Buyer as provided herein or of a
         court of competent jurisdiction except in the case of the Escrow
         Agent's gross negligence or willful misconduct.

                 (b)  The Escrow Agent may act in reliance upon and be
         protected in acting or refraining from acting upon any instrument or
         signature believed to be genuine and may assume that any person
         purporting to give any writing, notice, advice or instruction in
         connection with the provisions hereof has been duly authorized to do
         so.

                 (c)  The Escrow Agent may consult with counsel, auditors and
         other experts and any opinion of counsel or written opinion of such
         auditors or other experts shall be full and complete authorization and
         protection with respect to any action taken or suffered or omitted by
         the Escrow Agent thereunder in good faith and in accordance with such
         opinion of counsel or opinion of such auditors or other experts within
         the area of their respective expertise.

                 (d)  The Escrow Agent may execute any of its powers or
         responsibilities hereunder and exercise any rights hereunder either
         directly or by or through its agents or attorneys.  Nothing in this
         Agreement shall be deemed to impose upon the Escrow Agent any
         liability to any other person as a result of any failure of the Escrow
         Agent to qualify to do business or to act as fiduciary or otherwise in
         any jurisdiction other than the jurisdiction of its formation.

                 (e)  No property held in escrow by the Escrow Agent hereunder
         shall be subject to any setoff, counterclaim, recoupment, lien or
         other right which the Escrow Agent may have against either of the
         other parties hereto or against any other person for any reason
         whatsoever.

                 (f)  If any dispute arises between Buyer and Sellers as to
         which of them is entitled to delivery of the disputed portion of the
         Escrow Funds, or if the Escrow Agent is uncertain as to its
         obligations hereunder, the Escrow Agent may, but shall not be
         obligated to, either (i) commence an interpleader action against Buyer
         and Sellers in a state or federal court located in St. Louis,
         Missouri, and deposit the disputed Escrow Funds with such court,
         whereupon the Escrow Agent may apply to the court for an order
         discharging it from all further liability to any other party to this
         Agreement, or (ii) refrain from any action and continue to hold the
         disputed portion of the Escrow Funds pending a resolution of the
         dispute by either a court of competent jurisdiction or by a written
         agreement signed by Buyer and the Sellers.  For the purposes of any
         action or proceeding contemplated by clause (i) above, each party
         hereby consents to the jurisdiction of said courts and agrees that
         service of process in any such action or proceeding may be made by
         certified or registered mail at the address for notices to such party
         provided in this Agreement.

         6.  Expenses; Indemnification.  Each of (i) Buyer and (ii) Sellers as a
group agrees to pay one-half of any fees or expenses charged by the Escrow
Agent for its services to be performed hereunder.  The Escrow Agent shall bill
Buyer for all such fees and expenses, and Buyer shall remit payment to the
Escrow Agent on behalf of all the parties hereto.  Upon notice from Buyer,
Sellers shall immediately reimburse Buyer for Sellers' portion of such expenses
and fees.  In addition, Buyer and Sellers hereby agree jointly to indemnify the
Escrow Agent for, and to hold it harmless against, any loss, liability or
expense incurred without gross negligence or willful misconduct on the part of
the Escrow Agent, arising out of or in connection with its entering into this
Agreement and carrying out its duties hereunder, including the costs and
expenses of defending itself against any claim of liability.

         7.  Removal and Resignation.  The Escrow Agent may at any time be
removed by the written direction of Sellers and Buyer.  The Escrow Agent or any
successor escrow agent may at any time resign and be discharged of the agency
hereby created by giving written notice to each of Sellers and Buyer specifying
the date upon which it desires that such resignation shall take effect.  Such
removal or resignation shall take effect on the date specified in the notice of
removal or resignation, which date






                                    -10-
<PAGE>   11

shall not be earlier than 60 days after the giving of the notice of removal or
resignation unless a successor escrow agent shall have been appointed pursuant
to Section 8 hereof and shall have accepted such appointment, in which event
such removal or resignation shall take effect immediately upon the acceptance
by such successor escrow agent.  Buyer and Sellers shall take prompt steps to
have a successor escrow agent appointed in the manner hereinafter provided.

         8.  Appointment of Successor Escrow Agent.  If at any time the Escrow
Agent shall resign or be removed or if at any time a vacancy shall
occur in the office of the Escrow Agent for any other cause, a successor escrow
agent shall be appointed by a written instrument executed by Buyer and Sellers
and delivered to the Escrow Agent and the successor escrow agent.  Upon
acceptance of said instrument by the successor escrow agent, the resignation or
removal of the Escrow Agent shall become effective and such successor escrow
agent shall become vested with all the rights, powers, duties and obligations
of its predecessor hereunder.  If no successor escrow agent shall have been
appointed at the effective date of resignation of the Escrow Agent, the Escrow
Agent or either other party hereto shall petition a court of competent
jurisdiction for the appointment of a successor and the Escrow Agent's duties
shall be purely ministerial until such appointment is effective.

         9.  Termination.  This Agreement shall terminate upon the release of
all Escrow Funds held in the Escrow Accounts hereunder pursuant to
Section 4 hereof or upon written agreement of the parties hereto, which
agreement, in the case of the Escrow Agent, shall not be unreasonably withheld.

         10.     Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or by facsimile
transmission, or mailed by overnight delivery service or by registered or
certified mail (return receipt requested), postage prepaid, to the parties at

                        CONTINGENT PAYMENT AGREEMENT


         THIS CONTINGENT PAYMENT AGREEMENT (the "Agreement") made and entered
into this 4th day of May, 1995, by and among YOUNG DENTAL MANUFACTURING
COMPANY, a Missouri corporation ("Buyer"), THE RICHARD C. NEMANICK TRUST dated
July 25, 1978 ("Nemanick"), one of the stockholders of LORVIC HOLDINGS, INC., a

"Escrow Agent").  All capitalized terms not defined herein shall have the same
meanings as set forth in the Purchase Agreement (as herein defined).

         WHEREAS, Buyer and the stockholders of Lorvic Holdings, including
Nemanick, are parties to a certain Stock Purchase Agreement made as of May 4,
1995 (the "Purchase Agreement"), pursuant to which Buyer is purchasing all of
the capital stock of Lorvic Holdings and its wholly owned subsidiary, The
Lorvic Corporation, a Delaware corporation ("Lorvic Corporation");

         WHEREAS, Nemanick is willing to represent and warrant that for the tax
periods ending on or before the Closing Date of Lorvic Holdings and Lorvic
Corporation, neither Lorvic Holdings nor Lorvic Corporation shall have any tax
liabilities, together with any interest, penalties, additions to tax or
additional amounts with respect thereto, for any tax matter other than those
Lorvic Holdings represents and warrants to have been paid or properly reflected
on the Closing Balance Sheet pursuant to Section 3.1(o) of the Purchase
Agreement ("Excess Taxes");

         WHEREAS, Buyer desires to withhold Five Hundred Thousand Dollars
($500,000) (the "Initial Escrow Amount") from Nemanick and to make the payment
of the same contingent upon the expiration of the applicable statutes of
limitation without the assessment of any Excess Taxes which Nemanick represents
and warrants that neither Lorvic Holdings nor Lorvic Corporation owes; and

         WHEREAS, Buyer is willing to deposit the Initial Escrow Amount with
the Escrow Agent upon the terms hereof;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties hereto agree as follows:

         1.      Representation and Warranty of Nemanick.  Nemanick represents
and warrants to Buyer that for the tax periods of Lorvic Holdings and Lorvic
Corporation ending on or before Closing Date, neither Lorvic Holdings nor
Lorvic Corporation shall have any liability for Excess Taxes.  This
representation and warranty shall survive until such time as the assessment or
collection of any Excess Taxes with respect to any tax periods of Lorvic
Holdings or Lorvic Corporation ending on or before the
<PAGE>   2

Closing Date is prevented by the operation of any law or rule of law.

         2.      Establishment of Escrow Account.  The Escrow Agent shall
establish at is offices located at St. Louis, Missouri an escrow account (the
"Escrow Account") and shall cause all funds deposited into the Escrow Account
to be held, invested and distributed in accordance with the terms of this
Agreement.  The amount deposited into the Escrow Account, together with any
proceeds of investments thereof, that may be held in the Escrow Account from
time to time are hereinafter referred to as "Escrow Funds."  The Escrow Agent
shall keep appropriate records to reflect the current value from time to time
of the Escrow Funds, including appropriate adjustments for disbursements and
income earned and losses in respect thereof.

         3.      Delivery of Escrow Funds.  Buyer hereby agrees to deliver or
cause to be delivered to Escrow Agent in accordance with the terms of this
Agreement the Initial Escrow Amount, in cash, to be held hereunder as Escrow
Funds.

         4.      Investment of Escrow Funds.  The Escrow Funds shall be
invested and reinvested by the Escrow Agent in the Escrow Agent's Tax Exempt
Money Market Fund or, if otherwise specifically directed to do so by Buyer, in
obligations issued or guaranteed by any state or political subdivision thereof
(including stripped obligations the principal of and interest on which have
been separated and offered for sale separate from each other) and, rated in the
second highest category if rated as short term obligations or not lower than
the third highest category if rated as long term obligations by Moody's
Investors Service, Inc. ("Moody's") or by Standard & Poor's Corporation
("Standard & Poor's"), each of New York, New York, or their respective
successors.

         5.      Notice of Claim.  (a) Defense of Claim.  Promptly after the

Corporation of a claim that either Lorvic Holdings or Lorvic Corporation may be
liable for any Excess Tax (a "Claim"), Buyer shall promptly notify Nemanick.
Thereupon, Nemanick shall have the right, upon written notice (the "Defense
Notice") to Buyer within 30 days after receipt by Nemanick of notice of the
Claim (or sooner if such claim so requires) to conduct, at Nemanick's own
expense, the defense against the Claim.  In the event of a Claim, Nemanick
shall have the right to reasonable access to the pertinent documents and
records of Lorvic Holdings and/or Lorvic Corporation in the defense of a Claim.
The Defense Notice shall specify the counsel Nemanick shall appoint to defend
such Claim.  Buyer shall have the right to employ separate counsel in any such
Claim and/or participate in the defense thereof, but the fees and expenses of
such counsel shall not be included as part of any amount to be reimbursed
hereunder.  Nemanick shall apprise Buyer of all significant developments.  In

                      jurisdiction; and

             (ii)     All reasonable costs and expenses incurred in defending 
                      any Claim for Excess Tax in the event that Nemanick 
                      fails to provide a reasonable defense.

         The amount(s) subject to reimbursement pursuant to this Paragraph (b)
shall be calculated net of any amounts which have been previously recovered by
Buyer from other collateral sources (such as contractual indemnities of any
person which are contained outside this Agreement).

         6.      Earnings.  The Escrow Agent shall remit to Buyer, on or before
March 10 of each year during the term hereof, an amount, which shall be

the Escrow Funds for the prior calendar year.  Buyer shall pay all taxes due on
such earnings and shall indemnify and hold Nemanick harmless therefrom.

         compensation to which he is entitled under that certain Employment and
         Noncompetition Agreement dated May 4, 1995 between Richard C. Nemanick
         and Buyer.

Parties in the Escrow Funds shall not be subject to sale, assignment, transfer,
pledge, encumbrance or other disposition while held in the Escrow Account,

agency created by this Agreement upon the terms and conditions hereof and

except that:

                 (a)  The duties and obligations of the Escrow Agent shall be
         determined solely by the express provisions of this Agreement, and no
         implied covenants, duties or obligations shall be read into this
         Agreement against the Escrow Agent nor shall the Escrow Agent be bound
         by the provisions of any other agreements between the other parties
         hereto beyond the specific terms hereof; the Escrow Agent shall not be
         liable for any action taken, suffered or omitted by it in good faith
         and reasonably believed by it to be authorized or within the

         this Agreement; the Escrow Agent shall not be liable for any error of
         judgment made in good faith by a responsible officer or officers of
         the Escrow Agent, unless the Escrow Agent was grossly negligent in
         ascertaining the pertinent facts or in employing such officer or
         officers; and the Escrow Agent shall not be liable to any person with
         respect to any action taken, omitted or suffered to be taken by it in
         accordance with the provisions of this Agreement or in accordance with
         the written directions of Nemanick or Buyer as provided herein or of a
         court of competent jurisdiction except in the case of the Escrow
         Agent's gross negligence or willful misconduct.

                 (b)  The Escrow Agent may act in reliance upon and be
         protected in acting or refraining from acting upon any instrument or

         so.

                 (d)  The Escrow Agent may execute any of its powers or
         responsibilities hereunder and exercise any rights hereunder either

         liability to any other





                                      -4-
<PAGE>   5

         person as a result of any failure of the Escrow Agent to qualify to do
         business or to act as fiduciary or otherwise in any jurisdiction other
         than the jurisdiction of its formation.

                 (e)  No property held in escrow by the Escrow Agent hereunder
         shall be subject to any setoff, counterclaim, recoupment or other
         right which the Escrow Agent may have against either of the other
         parties hereto or against any other person for any reason whatsoever.

                 (f)  If any dispute arises between Buyer and Nemanick as to

         and Nemanick in any state court located within St. Louis County,
         Missouri, or federal court located in St. Louis, Missouri, and deposit
         the disputed Escrow Funds with such court, whereupon the Escrow Agent
         may apply to the court for an order discharging it from all further
         liability to any other party to this Agreement, or (ii) refrain from
         any action and continue to hold the disputed portion of the Escrow
         Funds pending a resolution of the dispute by either a court of
         competent jurisdiction or by a written agreement signed by Buyer and
         Nemanick.  For the purposes of any action or proceeding contemplated
         by clause (i) above, each party hereby consents to the jurisdiction of
         said courts and agrees that service of process in any such action or
         proceeding may be made by certified or registered mail at the address
         for notices to such party provided in this Agreement.

         10.  Expenses; Indemnification.  Each of (i) Buyer and (ii) Nemanick
agrees to pay one-half of any fees or expenses charged by the Escrow Agent for
its services to be performed hereunder.  In addition, Buyer and Nemanick hereby
agree jointly to indemnify the Escrow Agent for, and to hold it harmless
against, any loss, liability or expense incurred without gross negligence or
willful misconduct on the part of the Escrow Agent, arising out of or in
connection with its entering into this Agreement and carrying out its duties
hereunder, including the costs and expenses of defending itself against any
claim of liability.

         11.  Removal and Resignation.  The Escrow Agent may at any time be
removed by the written direction of Nemanick and Buyer.  The Escrow Agent or
any successor escrow agent may at any time resign and be discharged of the
agency hereby created by giving written notice to each of Nemanick and Buyer
specifying the date upon which it desires that such resignation shall take
effect.  Such removal or resignation shall take effect on the date specified in
the notice of removal or resignation, which date shall not be earlier than 60
days after the giving of the notice





                                      -5-
<PAGE>   6

of removal or resignation unless a successor escrow agent shall have been
appointed pursuant to Section 12 hereof and shall have accepted such
appointment, in which event such removal or resignation shall take effect
immediately upon the acceptance by such successor escrow agent.  In the event
of such removal or resignation, Buyer and Nemanick shall take prompt steps to
have a successor escrow agent appointed in the manner hereinafter provided.

         12.  Appointment of Successor Escrow Agent.  If at any time the Escrow
Agent shall resign or be removed or if at any time a vacancy shall occur in the
office of the Escrow Agent for any other cause, a successor escrow agent shall
be appointed by a written instrument executed by Buyer and Nemanick and
delivered to the Escrow Agent and the successor escrow agent.  Upon acceptance
of said instrument by the successor escrow agent, the resignation or removal of
the Escrow Agent shall become effective and such successor escrow agent shall
become vested with all the rights, powers, duties and obligations of its
predecessor hereunder.  If no successor escrow agent shall have been appointed
at the effective date of resignation of the Escrow Agent, the Escrow Agent or
either other party hereto shall petition a court of competent jurisdiction for
the appointment of a successor and the Escrow Agent's duties shall be purely
ministerial until such appointment is effective.

         13.  Termination.  This Agreement shall terminate upon the release of
all Escrow Funds held in the Escrow Account hereunder pursuant to Section 7
hereof or upon written agreement of the parties hereto, which agreement, in the
case of the Escrow Agent, shall not be unreasonably withheld.

         14.     Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or by facsimile
transmission, telexed or mailed by overnight delivery service or by registered

  Consultant's retention under this Agreement shall commence immediately at the
termination of the Employment Agreement (the "Effective Date"), and shall
continue until 12:00 a.m. on the date that Consultant turns sixty-five (65)
years of age, unless earlier terminated pursuant to the terms of this
Agreement.


                               IV.  COMPENSATION

  4.1  REGULAR COMPENSATION.  For all services rendered by Consultant during
the term of this Agreement, Consultant shall be entitled to receive regular

mutually agreed upon by the parties hereto.

  4.2  WITHHOLDING.  All payments shall be less such amounts as are required to
be withheld by federal, state or local law, if any.


                          V.  TERMINATION OF RETENTION

  5.1  TERMINATION BY CORPORATION.  Corporation may terminate Consultant's
retention pursuant to this Agreement in the event that Consultant during the
term of this Agreement shall be in Actual Default (as defined herein) under any
provision of this Agreement, or if Consultant has committed acts of gross
negligence, dishonesty or misconduct in carrying out his obligations or
responsibilities to the Corporation, as determined in the reasonable discretion
of the Board of Directors of the Corporation, by giving at least thirty (30)
days prior written notice to Consultant of Corporation's intention to terminate
this Agreement.  In the event of such termination by Corporation, Consultant
shall have the right to reasonable access to documents and records of
Corporation in a subsequent investigation by Consultant challenging the grounds
for termination.

<PAGE>   3

  In the event of any such termination by Corporation, Corporation shall be
obligated to continue to pay Consultant the compensation due Consultant under
this Agreement up to the termination date stated in said written notice so long
as Consultant continues to be ready, willing and able to perform all of
Consultant duties in accordance with this Agreement.

  5.2  TERMINATION BY CONSULTANT.  Consultant may terminate Consultant's
retention pursuant to this Agreement in the event that Corporation, during the
term of this Agreement, shall be in Actual Default (as defined herein) under
any provision of this Agreement, by giving at least sixty (60) days prior
written notice to Corporation of Consultant's intention to terminate this
Agreement.

  In the event of any such termination by Consultant, Corporation shall
continue to pay Consultant the salary due Consultant under this Agreement up to
the termination date stated in Consultant's written notice so long as
Consultant continues to perform all of Consultant duties in accordance with the
terms of this Agreement and so long as there is no earlier termination date
under any notice given by Corporation.

  5.3  TERMINATION BY MUTUAL AGREEMENT.  Consultant's retention under this
Agreement may be terminated at any time by mutual written agreement between the
parties hereto.

  5.4  COOPERATION BY CONSULTANT.  Following any such notice of termination,
Consultant shall fully cooperate with Corporation in all matters relating to
the winding up of Consultant's pending work on behalf of Corporation and the
orderly transfer of any such pending work to such other employees of
Corporation as may be designated by Corporation; and to that end Corporation
shall be entitled to such services of Consultant as Corporation may reasonably
require during all or any part of the period from the time of giving any such
notice until the effective date of such termination.

  5.5  SETTLEMENT OF ACCOUNTS.  After any termination of this Agreement, all
compensation and amounts due to Consultant with respect to work performed or
expenses incurred prior to the date of termination shall be reconciled with
amounts due to Corporation from Consultant.  Each party shall be entitled to
offset against any amounts that may be due to the other party such amounts as
are due from such other party to it or him.  The parties shall proceed
expeditiously to accomplish the foregoing, and the resulting amount due from
one party to the other shall be paid promptly after it is determined.

belong to and remain the property of Corporation.


                         VII.  CONFIDENTIAL INFORMATION

  7.1  NONDISCLOSURE BY CONSULTANT.  Consultant will not, except as authorized
by Corporation, during or at any time after the termination of Consultant's
retention with Corporation, directly or indirectly, use for himself or others,
or disclose, communicate, divulge, furnish to, or convey to any other person,
firm, or corporation, any secret or confidential information, knowledge or data
of Corporation or that of third parties obtained by Consultant during the
period of his retention with Corporation and such information, knowledge or
data includes, without limitation, the following:

  a) Secret or confidential matters of a technical nature such as, but not

     similar items or research projects involving such items;

     merchandising.

  7.2  SURRENDER OF INFORMATION.  Consultant, upon termination of his retention
with Corporation, or at any other time upon Corporation's written request,
shall deliver promptly to Corporation all drawings, blueprints, manuals,
letters, notes, notebooks, reports, sketches, formulae, computer programs and
similar items, memoranda, lists of customers, and all other materials and
copies thereof relating in any way to Corporation's business which contain
confidential information and which were in any way obtained by Consultant
during the term of his retention with Corporation which are in his possession
or under his control; and Consultant will not make or retain any copies of any
of the foregoing and will so represent to Corporation upon termination of his
retention.

  7.3 REMEDIES.  Consultant understands and acknowledges that the such
confidential information or other commercial ideas mentioned herein are unique
and that the disclosure or use of such matters or any other secret or
confidential information other than in furtherance of the business of
Corporation would reasonably be expected to result in irreparable harm to
Corporation; and that in addition to whatever other remedies Corporation and/or
its successors or assigns may have at law or in equity, Consultant specifically
covenants and agrees that, in the event of default under or breach of this
Agreement, Corporation and/or its successors and assigns shall be entitled to
apply to any court of competent jurisdiction to enjoin any breach, threatened
or actual, of the foregoing covenants and promises by Consultant, and/or to sue
to obtain damages for default under or any breach of this Agreement.  In the
event of default under or breach of this Agreement, Consultant hereby agrees to
pay all costs of enforcement and collection of any and all remedies and damages
under this Agreement, including reasonable attorneys' fees as determined by a
court of competent jurisdiction.


                             XIII.  ACTUAL DEFAULT

  In the event either party believes that the other party has failed to fulfill
any of his or its obligations under this Agreement, the party aggrieved by such
default shall give the other party written notice of such default specifying
the nature thereof.  If within thirty (30) days after the giving of such
notice, the alleged defaulting party has failed or refused to remedy such
default, the party aggrieved by such alleged default may by notice in writing
declare the alleged defaulting party to be in actual default ("Actual Default")
of this Agreement and proceed in the manner otherwise provided for herein.  The
provisions of this Section are intended to provide a means whereby the party
alleged to be in default under this Agreement will have an opportunity to cure
any such alleged default before the aggrieved party shall be entitled to
attempt to terminate this Agreement.  The giving of such notice and the
expiration of the thirty (30) day period provided for herein shall not,
however, prevent the alleged defaulting party from establishing that no default
did in fact exist.


                            IX.  BINDING ARBITRATION

  Any controversy or claim arising out of or relating to this Agreement, or the
breach thereof, shall be settled by arbitration in accordance with the Rules of
the American Arbitration Association at a mutually convenient location agreed
to by the parties or the arbitrators, and the parties hereby agree to be





                                      5
<PAGE>   6

bound by the results thereof.  Each party shall choose one arbitrator and a
third arbitrator shall be chosen by the two arbitrators so chosen by the
parties.  A judgment upon any award rendered by a majority opinion of the
arbitrators so chosen may be entered in any court having jurisdiction thereof.



                             X.  GENERAL PROVISIONS

  10.1  WAIVER.  The waiver by either party of a breach or violation of any
provision of this Agreement shall not operate as or be construed to be a waiver
of any subsequent breach hereof.

  10.2  SEVERABILITY.  Should any one or more sections of this Agreement be
found to be invalid, illegal, or unenforceable in any respect, the validity,
legality and enforceability of the remaining sections contained herein shall

hereof is found to be partially enforceable, then it shall be enforced to that
extent.

this Agreement shall be sufficient if furnished in writing and personally

Shoreline Court East, Earth City, Missouri 63045 or such other place as it may

their respective heirs, personal representatives, successors and assigns.

  10.9  ENTIRE AGREEMENT.  This is the entire and only Agreement between the
parties respecting the subject matter hereof.  This Agreement may be modified
only by a written instrument executed by all parties hereto.


  IN WITNESS WHEREOF, Corporation has caused this Agreement to be executed by
and its corporate seal to be affixed by its duly authorized officers, and

        dated December 31, 1991

        WHEREAS, the parties hereto believe it to be in the best interests of
the Stockholders and the Corporation to insure continuity of harmonious
management by restricting the transfer of the stock of the Corporation and to
insure that at a triggering event (which, for the purpose of this Agreement,
shall be defined as any event requiring a Stockholder to offer or sell stock)
said stock shall not pass into the control of persons whose interest might be
incompatible with the interest of the Corporation and the remaining
Stockholder(s):

        Now, in consideration of the mutual covenants exchanged and other
valuable consideration, it is hereby agreed as follows:

SECTION 6.1 MECHANICS

     (a) MECHANICS -- OPTIONAL PURCHASE.  Offers made to the Corporation and

Stockholder shall be free to dispose of its interest subject to the following
restrictions:

         (1)  Effect on Transferor.  The transferor shall continue to be bound

                              ESCROW AND DEFAULT

SECTION 7.1  (a) DEPOSIT

             The Stockholder whose stock is being purchased or redeemed, or its
legal representative, shall deposit the shares with an escrow agent who shall
be the Accountant for the Corporation at the time of redemption or purchase, or
such other party as may be mutually agreed to at that time.  The shares shall
be duly endorsed in blank for transfer and shall be accompanied by all other
documents necessary for an effective transfer, and the selling Stockholder
shall deposit with the escrow agent sufficient funds to pay for all necessary
transfer costs, if any.  The escrow agent shall cause the ownership of the
shares to be recorded in its name, and shall hold the shares until the full
redemption or purchase price is paid.

             (b) DIVIDENDS AND VOTE.  While the shares are on deposit with the
escrow agent and so long as the purchaser is not in default under this purchase
or redemption Agreement in the payment of the purchase or redemption price and
interest thereon, such purchaser shall have the right to all dividends and to
vote the shares deposited with the escrow agent and the escrow agent and the 
selling Stockholder shall, on demand, execute and deliver an effective proxy or
proxies in favor of the purchaser whenever


                                     - 11 -

<PAGE>   15
demand is made upon them for such proxy or proxies by the purchaser.  

        (c)  DELIVERY OF SHARES.  Simultaneously with the last payment of the
purchase or redemption price, the escrow agent shall deliver to the purchaser,
duly endorsed for transfer, all such shares and all other documents necessary
to transfer such shares.

        (d)  DEFAULT--LESS THAN 50% PAID FOR.  In the event that the purchaser
defaults in any payment of the purchase or redemption price and such default
continues for a period of thirty (30) days, and if such default occurs when
less than fifty (50%) percent of the principal purchase price shall have been
paid, the amounts theretofore received by the seller shall be retained as
damages, and in addition the escrow agent shall pay over to the seller any
dividends held by it and return the shares to the seller duly endorsed for
transfer; and the purchaser shall have no rights whatsoever in the shares.  In
addition, the seller may claim any decrease between the purchase price of the
shares returned to the seller and their fair market value as of the date of
default.  

        (e)  DEFAULT--MORE THAN 50% PAID FOR.  In the event such default occurs
at a time when the purchaser shall have paid fifty (50%) percent or more of the
principal purchase price, the escrow agent shall deliver to the seller, duly
endorsed for transfer, that portion of the shares whose then fair market value
equals the remaining unpaid purchase or redemption price, and shall


                                     - 12 -
<PAGE>   16
deliver the balance of the shares to the purchaser, duly endorsed for transfer,
together with all dividends held by it.  In such event the seller shall retain
the portion of the purchase price theretofore received by it.  No other claim
for damages shall be available to the seller.

        (f)  RESTRICTION.  Any shares returned to the seller by the escrow
agent because of the purchaser's default shall be subject to all restrictions
imposed by this Agreement.

        (g)  FEES.  The fees and all other expenses of the escrow agent shall
be split by the purchaser and seller.

SECTION  7.2   EVENTS OF DEFAULT

        A default of this Agreement shall occur in any of the following
events.  Any delay on the part of the seller in exercising any rights hereunder
shall not operate as a waiver of said rights and acceptance of any payment
after its due date shall not be deemed a waiver of the right to require prompt
payment when due of all other sums, and the acceptance of any payment after the
seller has declared the entire indebtedness due and payable shall not cure any
default of the purchaser or operate as a waiver of any rights of the seller
hereunder. 

        The events of default are:

        (a)  Any violation of this Agreement which, after thirty (30) days'
notice, is not cured by the violating party.

                              Company to the employee or any other value as
                              allowed by the owner in the subsequent year of
                              purchase.  The employee can make the purchase up
                              to fourteen days after the date of payment of the
                              profit sharing bonus or the date of appraisal for
                              the prior year's valuation, whichever is later.
                              The price per share shall be determined as in
                              PRICE OF SHARES.  This offer may be withdrawn at

     the Company in writing to unilaterally terminate the S election.

Disclosures of Information:
     Each Employee recognizes and acknowledges that it will have access to      
     certain confidential information of the Company and of entities affiliated

The Stock Plan Agreement, dated September 16, 1992, between and among employee,

        1.  The parties acknowledge that Company has terminated its election to
            be taxed under Chapter S of the Internal Revenue Code, and, on that

            "Chapter S Status".

        2.  Replace any and all references to "George E. Richmond" with "George

            Thereto."

                                     WAIVER

I, Dwayne K. Chipman, agree to waive any and all liability against George E.
Richmond, an individual, and Young Dental Manufacturing Company, a corporation,
and its directors and officers due to the Young Dental common stock valuation
as determined by Grace & Company, P.C. and received by Young Dental on March,
1993.  I understand that said valuation was affected by the decision by Young
Dental to change its tax status from an "S" corporation to a "C" corporation.
I further understand that if such change in tax status had not been taken into
account by Grace & Company, P.C., the resulting valuation could have been
materially different from the March, 1993 valuation Young Dental received from
Grace & Company, P.C.  On the basis of the above, I hereby agree that the
March, 1993 valuation is the proper valuation to use relative to the exercise
of any rights I may have as set forth in my September 16, 1992 stock agreement
with George E. Richmond, Young Dental, and me.

                              PROFIT SHARING PLAN
                           Effective January 1, 1987

PURPOSE:    To reward salaried employees, other than the CEO, who have
            contributed to the Company's profits in excess of corporate
            standards for shareholder return, and to compensate salaried
            employees for unique contributions.

DEFINITIONS:Company Profits shall mean Net Operating Income after CEO Bonus
            (as hereinafter defined) for the period and shall exclude long term
            gains or losses from sale or disposition of assets, write up of long
            term liabilities, or other unusual gains or losses as are determined
            at the sole discretion of the CEO.  The intent is to reward
            employees for profits generated from normal operations of the
            business.

            CEO Bonus -- Regardless of the amount of bonus paid to the CEO, the
            CEO bonus used for profit sharing shall be calculated as follows:
            [Net Operating Income - (January 1st N.W. x .22)] x .30 = Amount to
            be deducted from Net Operating Income for profit sharing
            calculations.

            Salaried Employees shall mean all employees paid under the salaried
            payroll as opposed to the hourly payroll.

            Net operating income shall be as per financial statements prepared
            by the corporation's accounting firm.

            Net Worth shall mean the net value of shareholders' equity which
            would include but not be limited to Capital Stock, paid in surplus,
            and Retained earnings less Treasury Stock.

                                      -2-

            Eligible Employee shall mean a full-time salaried employee, employed
            in a salaried position continuously from some time during the profit
            sharing year until June 15 of the following year except that
            approved leaves of absence shall not be considered as interruption
            of employment.  Employees who are not employed due to disability or
            death at June 15 may be paid or their Estate paid all or a portion
            of their allocated profit sharing bonus as determined by the CEO at
            his/her sole discretion.

THE PLAN:   Twenty percent (20%) of the January 1st Net Worth is set aside from
            the Net Operating Income as adjusted per CEO Bonus caluclation for
            the period as a return on investment for the shareholders.  After
            the 20% return has been deducted from Net Operating Incomve (as
            adjusted per CEO bonus calculation) the resulting balance is
            multiplied by Thirty Percent (30%) and this resulting number becomes
            the profit sharing pool for the eligible employees.  Sixty Percent
            (60%) of this pool shall be allocated to each then eligible employee
            based upon his/her earnings exclusive of prior years profit sharing
            distribution, special awards or payments, retirement payments or
            other unusual or non-base pay compensation.  The balance of the pool
            (the Discretionary Pool) Forty Percent (40%) shall be
<PAGE>   3
                                     -3-


            allocated by the CEO based upon his/her knowledge of special
            contributions to profits made by individual employees.  The
            discretion of the CEO is final in this allocation and may not be
            contested in any manner by any employee.  This does not exclude the
            CEO's right to consult with supervisory personnel for their input as
            to proper allocation of this Discretionary Pool.  The distributions
            of profit sharing monies shall be made to all eligible employees on
            June 15th following the end of the corporate year for which such
            profit sharing has been earned.  Any monies allocated to then
            eligible employees who are not eligible at date of distribution
            shall be credited back to the company and be included in operating
            income or may be set aside for profit sharing for the then current
            year at the sole discretion of the CEO.

INTERPRETATION:  Any debate or need to interpret the meaning of this plan shall
            be at the sole discretion of the Chief Executive Officer.

     1.9   COMPUTATION OF TIME PERIODS.  In this Agreement, in the computation
of periods of time from a specified date to a later specified date, the word
"from" shall mean "from and including" and the words "to" and "until" shall

2    COMMITMENTS.  Subject to the terms and conditions hereof, and in reliance 
upon the representations and warranties of Borrower herein:

     2.1   REVOLVING COMMITMENT.  Lender commits to make advances to Borrower
(each a "Revolving Advance") from time to time during the period commencing on
the Effective Date and ending at the close of business on the day preceding
December 1, 1999 (the "Ultimate Revolving Maturity Date"). (The from time to
time outstanding principal balance of all Revolving Advances from the Lender is
referred to herein as the "Revolving Loan".)  The obligation of Borrower to
repay the Revolving Loan shall be evidenced by a promissory note payable to the
order of Lender in a maximum principal amount equal to the Revolving Commitment
(the "Revolving Note") satisfactory to Lender.  Amounts applied to reduce the
Revolving Loan may be reborrowed as Revolving Advances as provided herein.  At
any time after an Event of Default occurs that is not waived in writing by
Lender, Lender may cancel the Revolving Commitment as provided in Section 18.3.

           2.1.1  LIMITATION ON REVOLVING ADVANCES.  No Revolving Advance will 
     be made which would result in the Revolving Loan exceeding the Revolving   
     Commitment.  Lender may, however, in its sole discretion make such
     Revolving Advances, but shall not be deemed by doing so to have increased
     the Revolving Commitment and shall not be obligated to make any such
     Revolving Advances thereafter. No Revolving Advance will be made on or
     after the Ultimate Revolving Maturity Date.

           2.1.2  DEFINITION OF REVOLVING COMMITMENT.  The "Revolving 
     Commitment" on any date shall be $6,500,000, or such lesser Dollar amount
     to which it may have been reduced as provided herein.

     2.2 TERM COMMITMENT. Lender commits to make a term loan to Borrower of
$12,000,000 (the "Term Commitment").  The Term Loan will be made in a single
advance on the Effective Date (the "Term Advance").  (The from time to time
outstanding principal amount of the Term Advance is referred to herein as the
"Term Loan".)  The obligation of Borrower to repay the Term Loan shall be
evidenced by a promissory note payable to the order of Lender satisfactory to
Lender (the "Term Note").   Amounts applied to reduce the Term Loan may not be
reborrowed.


3    INTEREST.       

     3.1   RATES.

           3.1.1  REVOLVING LOAN.  The Revolving Loan shall bear interest at a
     per annum rate equal to the CBR minus 0.5%.


                                      2
<PAGE>   4



           3.1.2 TERM LOAN.  The Term Loan shall bear interest per annum rate
     equal to the CBR plus the CBR Increment.  The "CBR Increment" shall be
     equal to 0.25%; provided, however, if Borrower enters into a Rate
     Agreement acceptable to Lender, the CBR Increment shall be equal to 0.0%. 
     Notwithstanding the foregoing, Borrower may elect to convert the rate per
     annum at which all or a portion of the Term Loan bears interest to the
     Adjusted LIBOR Rate.  The "Adjusted LIBOR Rate" shall be an annual rate of
     two and one-half percent (2.50%) plus an interest rate equal to the
     quotient (rounded to the nearest 0.001%) of the interest rate at which
     Dollar deposits in immediately available funds and for a maturity nearest
     in duration to the applicable Interest Period are offered or available in
     the London Interbank Market for Eurodollars as of 11:00 a.m. (St. Louis
     time) two Business Days before the applicable adjustment date, as reported
     on Telerate Screen LIBO page 3750 (rounded to the nearest 1/16%).  The
     "Interest Period" shall, at Borrower's option, be no less than 30 days nor
     more than 180 days.

     3.2   RATE AFTER MATURITY.  Borrower shall pay interest on a Loan after its
Maturity, and (at the option of Lender) upon all the Loans and other amounts 
that are owing with respect thereto after the occurrence of an Event of 
Default, at a per annum rate equal to CBR plus 3.0%.

     3.3   TIME OF ACCRUAL.  Interest shall accrue on all principal amounts
outstanding from and including the date when first outstanding to but excluding
the date when no longer outstanding.  Amounts shall be deemed outstanding until
payments are applied thereto as provided herein.

     3.4   COMPUTATION.  Interest shall be computed for the actual days
elapsed over a year deemed to consist of 360 days.  Interest rates that are
based on the CBR shall change simultaneously with any change in the CBR and
such rates shall be effective for the entire day on which such CBR change
becomes effective.

     3.5   USURY.  Notwithstanding any provisions to the contrary in Section
3 or elsewhere in any of the Loan Documents, Borrower shall not be obligated to
pay interest at a rate which exceeds the maximum rate permitted by Law.  If,
but for this Section 3.5, Borrower would be deemed obligated to pay interest at
a rate which exceeds the maximum rate permitted by Law, or if any of the Loan
Obligations is paid or becomes payable before its originally scheduled Maturity
and as a result Borrower has paid or would be obligated to pay interest at such
an excessive rate, then (i) Borrower shall not be obligated to pay interest to
the extent it exceeds the interest that would be payable at the maximum rate
permitted by Law; (ii) any such excess interest that has been paid by Borrower
shall be refunded; and (iii) the effective rate of interest shall be deemed
automatically reduced to the maximum rate permitted by Law.

4    FEES.

     4.1 REVOLVING COMMITMENT FEE.  Borrower shall pay to lender a
"Revolving Commitment Fee" calculated by applying the daily equivalent of an
annual rate of 0.125% to the Unused Revolving Commitment on each day during the
period from and including the Effective Date to but  excluding the Ultimate
Revolving Maturity Date.  The "Unused Revolving


                                      3
<PAGE>   5

Commitment" on any day shall be the difference between (i) the amount of the    
Revolving Commitment and (ii) the Revolving Loan as of the close of business on
such day.  The Revolving Commitment Fee shall be payable quarterly, in arrears,
commencing on the first day of October, 1996 and continuing on the first day of
each January, April, July and October thereafter and upon the Ultimate
Revolving Maturity Date.

     4.2 CALCULATION OF FEES.  All of the foregoing fees that are based on
an annual percentage shall be calculated on the basis of a year deemed to
consist of 360 days and for the actual number of days elapsed.

5    PAYMENTS.

     5.1 SCHEDULED PAYMENTS ON REVOLVING LOAN.


           5.1.1  INTEREST.  Borrower shall pay interest accrued on the 
     Revolving Loan monthly in arrears, beginning on the first day of the first
     full calendar month following the Effective Date, and continuing on the
     first day of each calendar month thereafter, and on the Ultimate Revolving
     Maturity Date.  Borrower shall pay interest accrued on the Revolving Loan
     after the Ultimate Revolving Maturity Date on demand.
           
           5.1.2  PRINCIPAL.

                  5.1.2.1  DAILY PAYMENTS.  Borrowers shall maintain one or 
           more lockboxes with Lender under its standard lockbox agreements (the
           "Lockboxes").  Borrower shall also maintain one or more accounts
           with Lender, each designated a "Controlled Disbursement Account". 
           Lender will also establish on its books an account in the name of
           Borrower designated as the "Cash Collateral Account". Borrower shall
           direct all Account Debtors to remit payments on their Accounts to
           one or another of the Lockboxes.  If sales of Inventory are made for
           cash, Borrower shall immediately deliver to Lender or deposit into
           the Cash Collateral Account the identical checks, cash or other
           forms of payment which Borrower receives. All proceeds of Collateral
           and all funds Borrower receives directly (other than Revolving
           Advances) shall be deposited in the Cash Collateral Account.
           Deposits in the Cash Collateral Account each day will be applied by
           Lender to the Revolving Loan in accordance with Section 5.4 until the
           Revolving Loan has been reduced to zero. 

                  5.1.2.2 ULTIMATE REVOLVING MATURITY DATE.  Borrower shall
           repay the entire Revolving Loan on the Ultimate Revolving Maturity
           Date.

     5.2   SCHEDULED PAYMENTS ON TERM LOAN.

           5.2.1 INTEREST.  Borrower shall pay interest accrued on the Term 
     Loan monthly in arrears, beginning on the first day of the first full
     calendar month following the Effective Date, and continuing on the first
     day of each calendar month thereafter, and on December 1, 1999 (the
     "Ultimate Term Maturity Date").  Borrower shall pay interest accrued on
     the Term Loan after the Ultimate Term Maturity Date on demand.

Borrower shall make a final installment equal to the remaining outstanding
principal balance on the Ultimate Term Maturity Date.

     5.3   PREPAYMENTS AND REDUCTION OF COMMITMENTS.


           5.3.1  VOLUNTARY.

                  5.3.1.1   REVOLVING LOAN.  Borrower may reduce the Revolving  
           Commitment in whole multiples of $500,000 at any time and from time
           to time, but only if (i) Borrower gives Lender written notice of
           Borrower's intention to make such reduction at least one Business
           Day prior to the effective date of the reduction, and (ii) Borrower
           makes on the effective date of the reduction any payment on the
           Revolving Loan required under Section 5.3.2.1 as a consequence of the
           reduction.  Any such reduction of the Revolving Commitment shall be
           permanent.

                  5.3.1.2  TERM LOAN.  Borrower may wholly prepay the Term  Loan
           at any time, and may make partial prepayments on the Term Loan in 
           amounts equal to up to the next two following scheduled payments of
           principal from time to time, but only if (i) Borrower gives Lender
           written notice of Borrower's intention to make such prepayment at
           least one Business Day prior to tendering the prepayment, and (ii)
           Borrower pays any accrued interest on the amount prepaid at the time
           of such prepayment.  Each partial prepayment on the Term Loan shall
           be applied to the next principal installment due hereunder.

                  5.3.1.3   PREMIUMS.  No penalty or premium shall be payable 
           upon any reduction by Borrower in the Revolving Commitment. No 
           penalty or premium shall be payable upon any prepayment of the Term
           Loan. 

           5.3.2  MANDATORY.


                                      5
<PAGE>   7



                  5.3.2.1   OVER-ADVANCES.  If at any time the Revolving Loan
           exceeds the Revolving Commitment, whether as a result of an optional
           Revolving Advance by Lender as contemplated by Section 2.1.1 or
           otherwise, Borrower shall on demand make a payment to Lender in the
           amount of the excess.  Each such prepayment shall be applied to
           reduce the Revolving Loan.

                  5.3.2.2  PROCEEDS FROM SALES OF ASSETS.  If Borrower sells any
           of its assets in a single transaction or related series of 
           transactions that are not in the ordinary course of business, 
           Borrower shall make a prepayment on the Term Loan in the amount of 
           the gross proceeds therefrom less reasonable selling expenses and 
           the increment in federal, state and local income taxes, if any, 
           payable as a consequence of any taxable gain from such sale.  If, 
           however, Borrower expends the net proceeds of any such sale of a
           capital asset within 90 days of completion of the sale for 
           replacement of such asset by another asset of comparable type and
           utility; and provided that such expenditure will not result in
           Borrower exceeding the limits for Capital Expenditures set forth in
           Section 17.1 of this Agreement, then Borrower shall not be required
           to make such prepayment.  Notwithstanding the foregoing, the net
           proceeds from Lorvic's sale of the Real Property Collateral situated
           at 8810 Frost Avenue, St. Louis, Missouri ("Lorvic Property"),
           Dental's sale of the Real Property Collateral situated at 2418
           Northline Industrial, Maryland Heights, Missouri ("Maryland Heights
           Facility") and the redemption of Borrower's interest in that certain
           Allegheny County, Pennsylvania Airport Revenue Bond, Due 2019, in
           the original principal amount of $100,000 and that certain Lower
           Colorado River Authority Texas Revenue Bond, Due 2009, in the
           original principal amount of $100,000 shall be applied to the
           Revolving Loan. The Revolving Commitment shall be automatically and
           permanently reduced by an amount equivalent to the net proceeds
           arising from the sale of the Lorvic Property.  Borrower shall be
           permitted to finance the sale of its assets by accepting notes for
           such Indebtedness; provided, however, that such financing from time
           to time does not exceed $150,000 in the aggregate and that the
           proceeds of such notes shall be paid to Lender if not expended to
           replace the asset sold.

                  5.3.2.3   PROCEEDS  FROM SALE OF SECURITIES.  If after the 
           Execution Date Borrower issues any equity or debt securities, or
           warrants or options therefor ("Securities"),  Borrower shall make a  
           prepayment on the Term Loan promptly after such sale in an amount
           equal to the gross proceeds therefrom less reasonable brokers' and
           underwriters' fees and commissions and other reasonable issuing
           expenses ("Securities Proceeds").  Subject to Section 5.3.1.2,
           Securities Proceeds not in excess of $2,000,000, in the aggregate,
           resulting from the sale of Securities to Persons which are employees
           of Borrower shall be applied to the next scheduled payments on the
           Term Loan.
            
                  5.3.2.4   APPLICATION OF INSURANCE/CONDEMNATION PROCEEDS.    
           Immediately upon receipt by Borrower of any Insurance/Condemnation 
           Proceeds, Borrower shall make a prepayment on the Revolving Loan in
           the amount of such Insurance/Condemnation Proceeds.  On the 90th day
           after


                                      6
<PAGE>   8

           receipt by Borrower of any Insurance/Condemnation Proceeds, Borrower
           shall make a prepayment on the Term Loan in the amount of such 
           Insurance/Condemnation Proceeds that have not, within the 90 day 
           period following Borrower's receipt of such Insurance/Condemnation 
           Proceeds, been either expended, or committed to be expended, by 
           Borrower for the purpose of rebuilding, repairing or replacing the 
           property for which such Insurance/Condemnation Proceeds were paid.


     Except as otherwise provided above, each prepayment under this Section
     5.3.2  that is required to be applied to reduce the Term Loan shall be
     applied to the scheduled principal installments in the inverse order of
     their due dates, except that the net proceeds from the sale of any Real
     Property Collateral (not including the Lorvic Property and the Maryland
     Heights Facility) shall be applied to the next scheduled principal
     payments on the Term Loan, subject to Section 5.3.1.2.  If application to
     the Term Loan of any prepayment required under this Section 5.3.2 reduces
     the Term Loan to zero, the remaining amount of such prepayment shall be
     applied to reduce the Revolving Loan and the Revolving Commitment shall be
     automatically and permanently reduced by an equivalent amount.

     5.4   MANNER OF PAYMENTS AND TIMING OF APPLICATION OF PAYMENTS.


           5.4.1   PAYMENT REQUIREMENT.  Unless expressly provided to the       
     contrary elsewhere herein, Borrower shall make each payment on the Loan
     Obligations to Lender as required under the Loan Documents in Dollars at
     the Applicable Lending Office on the date when due, without deduction,
     set-off or counterclaim.

           5.4.2   APPLICATION OF PAYMENTS.  All payments received by Lender
     in immediately available funds at or before 2:00 p.m., St. Louis time, on
     a Business Day will be applied to the relevant Loan Obligation on the same
     day.  Such payments received on a day that is not a Business Day or after
     2:00 p.m. on a Business Day will be applied to the relevant Loan
     Obligation on the next Business Day.

           5.4.3   INTEREST CALCULATION.  Section notwithstanding, for purposes
     of interest calculation only, any payment received by Lender (whether by
     cash, check, draft, wire transfer or other instrument) shall be deemed to
     have been applied to the relevant Loan Obligation on the Business Day such
     funds are deemed collected at or before 2:00 p.m., St. Louis time.

           5.4.4   RETURNED CHECKS.  If a payment is made by check, draft or
     other instrument and the check, draft or other instrument is returned to
     Lender unpaid, the application of the payment to the Loan Obligation will
     be reversed and will be treated as never having been made. 


     5.5   DUE DATES NOT ON BUSINESS DAYS.  If any payment required hereunder
becomes due on a date that is not a Business Day, then such due date shall be 
deemed automatically extended to the next Business Day.

6    BORROWING PROCEDURE AND LIMITS.

     6.1   INITIAL ADVANCES.

           6.1.1  REVOLVING ADVANCES.  Lender will make the initial Revolving
     Advance on the Effective Date as directed by Borrower in a written
     direction delivered to Lender. The manner of disbursement shall be subject
     to Lender's approval.

           6.1.2  TERM ADVANCE.  Lender will make the Term Advance on the
     Effective Date as directed by Borrower in a written direction delivered to
     Lender.  The manner of disbursement shall be subject to Lender's approval.

     6.2   SUBSEQUENT ADVANCES.

           6.2.1   REVOLVING ADVANCES.  Subsequent Revolving Advances will be 
     made only as follows:

                6.2.1.1   ADVANCES TO CONTROLLED DISBURSEMENT ACCOUNT.  Subject
           to the limitations in Section 2.1.1, on each Business Day a Revolving
           Advance will be made automatically by Lender to fund the total
           Dollar amount of checks and drafts presented to Lender for payment
           from the Controlled Disbursement Account.

                6.2.1.2   REVOLVING ADVANCE REQUESTS BY BORROWER. Subject to
           the limitations in Section 2.1.1, Borrower may also request a
           Revolving  Advance by submitting a Revolving Advance Request to
           Lender. Only a  written request (which may be mailed, personally
           delivered or telecopied as provided in Section 19.1) from a
           Borrowing Officer to Lender that specifies the amount of the
           Revolving Advance to be made and  the date the proceeds of the
           Revolving Advance are requested to be  made available to Borrower
           (the "Revolving Advance Date") shall be  treated as a "Revolving
           Advance Request".  A Revolving Advance  Request received by Lender
           on a day that is not a Business Day or  that is received by Lender
           after 2:00 p.m., St. Louis time, on a  Business Day shall be treated
           as having been received by Lender at  2:00 p.m., St. Louis time, on
           the next Business Day.  A Revolving  Advance Request shall become
           irrevocable a 2:00 p.m., St. Louis  time, on the Revolving Advance
           Date unless it is sooner revoked by  a Borrowing Officer.  Lender
           shall incur no liability to Borrower for treating any such request
           as a Revolving Advance Request or for treating a revocation thereof
           as such if Lender believes in good  faith that the Person making the
           request or revocation is a  Borrowing Officer.  Lender shall also
           incur no liability to Borrower for failing to treat any such request
           as Revolving Advance Request  or for treating a revocation thereof
           as such if Lender believes in  good faith that the Person making the
           request or revocation is not a Borrowing Officer.  Each Revolving
           Advance Request by a borrowing officer shall constitute a
           certification by Borrower (i) no Default has occurred that is
           continuing and not waived in writing by Lender, (ii) all
           representations and warranties of Borrower in this  Agreement are
           then true,

                                      8
<PAGE>   10
           

           and will be true on the Revolving Advance Date, as if then
           made, and  (iii) all conditions precedent hereunder to the making of
           the requested Revolving Advance have been satisfied.  Provided that
           all conditions precedent herein to a requested Revolving Advance
           have been satisfied, Lender will make the amount of such requested
           Revolving Advance available to Borrower on the Revolving Advance
           Date in immediately available funds in Dollars at the Applicable
           Lending Office.

                6.2.1.3.  LENDER'S RIGHT TO MAKE OTHER REVOLVING ADVANCES. 
           Lender shall have the right to make Revolving Advances at any time
           and from time to time to cause timely payment  of any of the Loan
           Obligations.  Lender will give notice to Borrower after making any
           such Revolving Advance.

7    APPORTIONMENT, APPLICATION AND REVERSAL OF PAYMENTS.  If an Event of 
Default has occurred and is continuing, Lender shall determine in its 
discretion the order and manner in which proceeds and other payments that Lender
receives are applied to the Loan Obligations, and Borrower hereby irrevocably
waives the right to direct the application of any payment or proceeds.  Lender
shall have the continuing and exclusive right to apply and reverse and reapply
any and all such proceeds and payments to any portion of the Loan Obligations.

8    INDEMNITY FOR RETURNED PAYMENTS.  If  after receipt of any payment
of, or proceeds applied to the payment of, all or any part of the Loan
Obligations, Lender is for any reason compelled to surrender such payment or
proceeds to any Person because such payment or application of proceeds is
invalidated, declared fraudulent, set aside, determined to be void or voidable
as a preference, an impermissible setoff, or a diversion of trust funds, or for
any other reason, then the Loan Obligations or part thereof intended to be
satisfied shall be revived and this Agreement shall continue in full force and
Borrower shall be liable to pay to Lender, and hereby does indemnify Lender and
hold Lender harmless for, the amount of such payment or proceeds surrendered. 
The provisions of this Section shall be and remain effective notwithstanding
any contrary action which may be taken by Lender in reliance upon any such
payment or application of proceeds, and any such contrary action so taken shall
be without prejudice to Lender's rights under this Agreement and shall be
deemed to have been conditioned upon such payment or application of proceeds
having become final and irrevocable.  The provisions of this Section shall
survive termination of the Commitments, the expiration of the any letters of
credit issued by Lender for the account of Borrower and the payment and
satisfaction of all of the Loan Obligations.


9    CAPITAL ADEQUACY REIMBURSEMENT.  If there is any change of Law after the
Execution Date regarding the capital that financial institutions
in a class that includes Lender are required to maintain and which has the
effect of reducing the rate of return on, or increasing the cost of
maintaining, Lender's capital as a consequence of its obligations hereunder,
then Lender may from time to time demand, and Borrower shall pay to Lender
within sixty days after each demand, such additional amount as will compensate
Lender for such reduction or increase.  If Lender claims  compensation under
this Section, Lender shall furnish a certificate to Borrower that states the
additional amount to be paid to it hereunder and includes a description of the
method used by Lender in calculating such amount. Borrower shall have the
burden of proving that any such certificate is not correct.  If there is any
change of Law after the Execution Date regarding the capital that financial
institutions in a class that includes
                                      
                                      9
<PAGE>   11

Lender are required to maintain and which has the effect of increasing the 
rate of return on, or decreasing the cost of maintaining, Lender's capital
as a consequence of its obligations hereunder, then Borrower may from time to
time demand, and Lender shall pay to Borrower within sixty days after each
demand, such additional amount as will compensate Borrower for such reduction or
increase. In addition, if Borrower shall fully satisfy the Loan Obligations
within sixty days of receiving the notice referred to above, Lender shall waive
the additional amount payable.

foregoing; and (xi) do anything that Lender's deems necessary in its reasonable
discretion to assure that the Loan Obligations are fully paid.

     under subpart (iii) of this Section 15.8.1 until any such claim or

relevant to the continuing ability of Borrower timely to pay and perform the
Loan Obligations.

     15.23 PROFORMAS FOR PERMITTED ACQUISITIONS.  Borrower shall, prior to 
making any Permitted Acquisition, prepare and furnish to Lender proforma        
financial statements for the Person to be acquired, or the Surviving Person if
the acquisition is to be by merger, demonstrating to the satisfaction of Lender
that none of the covenants in Section 17 will be violated as a consequence of
such acquisition or with the passage of time thereafter.  Such proforma
financial statements shall contain forecasted balance sheets, income
statements, statements of cash flows and such other reports and disclosures,
and shall cover such forecast periods, as the Lender may in its sole discretion
require.

     15.24 RATE PROTECTION AGREEMENTS.  On or prior to the expiration or 
termination of the Rate Agreement, if any, in effect on the date hereof,        
Borrower shall secure a replacement Rate Agreement with a counterparty whose
rating with Standard & Poor's Corporation or Moody's Investors Service, Inc. is
equal to or better than the counterparty in the initial agreement, with terms
substantially identical to those contained in the Rate Agreement in effect on
the date hereof with respect to a notional principal amount equal to or greater
than the amount of the Revolving Commitment, extending through the Ultimate
Term Maturity Date.  Borrower shall take all actions necessary to provide that
the replacement Rate Agreement will be pledged as security for the  Loans in
the same manner as the Rate Agreement in effect on the date hereof.

     15.25 ACQUISITION AGREEMENT.  Borrower shall fully perform all of its 
obligations under the Acquisition Agreement, and shall enforce all of its       
rights and remedies thereunder as it deems appropriate in its reasonable
business judgment; provided, however, that Borrower shall not take any action   
or fail to take any action which would result in a waiver or other loss of any
material right or remedy of Borrower thereunder.  Without limiting the
generality of the foregoing, Borrower shall take all action necessary or
appropriate to permit, and shall not take any action which would have any
adverse effect upon, the full enforcement of all indemnification rights under
the Acquisition Agreement.  Borrower shall not, without Lender's prior written
consent (which shall not be withheld unreasonably), modify, amend, supplement,
compromise, satisfy, release or discharge the Acquisition Agreement, any
collateral securing the same, any Person liable directly or indirectly with
respect thereto, or any agreement relating to the Acquisition Agreement or the
collateral therefor.  Borrower shall notify Lender in writing promptly after
Borrower becomes aware thereof, of any event or fact which could give rise to a
claim by it for indemnification under the Acquisition Agreement, and shall
diligently pursue such right and report to Lender on all further developments
with respect thereto.  Borrower shall remit directly to Lender, for application
to the Revolving Loan in such order as Lender determines, all amounts received
by Borrower as indemnification or otherwise pursuant to the Acquisition
Agreement.  If Borrower fails after Lender's demand to pursue diligently any
right under the Acquisition Agreement, or if an Event of Default exists, then
Lender may directly enforce such right in its own or Borrower's name and may
enter into such

                                      33
<PAGE>   35


settlements or other agreements with respect thereto as Lender determines.      
Notwithstanding the foregoing, Borrower shall at all times remain liable to
observe and perform all of its duties and obligations under the Acquisition
Agreement, and Lender's exercise of any of its rights with respect to the
Collateral shall not release Borrower from any of such duties or obligations.  
Lender shall not be obligated to perform or fulfill any of Borrower's duties or
obligations under the Acquisition Agreement or to make any payment thereunder,
or to make any inquiry as to the sufficiency of any payment or property
received by it thereunder or the sufficiency of performance by any party
thereunder, or to present or file any claim, or to take any action to collect
or enforce any performance or payment of any amounts, or any delivery of any
property.

     15.26 EARTH CITY FACILITY.  Borrower shall complete construction of the
expansion of the Earth City Facility in accordance with the plans, 
specifications, budget, construction schedule and Contracts relating thereto. 
Such expansion of the Earth City Facility shall be substantially complete
(subject to minor punch-list items) no later than October 31, 1996.  The Earth
City Facility shall be constructed within the boundaries of Real Property
Collateral in accordance with all Laws, free of all claims or Encumbrances for
labor or material.

     15.27 FURTHER ASSURANCES.  Borrower shall execute and deliver, or cause to
be executed and delivered, to Lender such documents and agreements, and shall   
take or cause to be taken such actions, as Lender may from time to time request
to carry out the terms and conditions of this Agreement and the other Loan
Documents.

     15.28 DATE-DOWN ENDORSEMENT.  Following completion of the construction 
arising out of the expansion of the Earth City Facility, Borrower shall provide 
Lender with an endorsement to Lender's Policy of Title Insurance issued by such
title company on the Earth City Facility which insures the priority of Lender's
Security Interest against all mechanics liens arising out of the expansion of
the Earth City Facility.

           18.1.9   BANKRUPTCY; INSOLVENCY; ETC.  A Covered Person (i) fails to
     pay, or admits in writing its inability to pay, its debts as they become   
     due, or otherwise becomes insolvent (however evidenced); (ii) makes an
     assignment for the benefit of creditors; (iii) files a petition in
     bankruptcy, is adjudicated insolvent or bankrupt, petitions or applies to
     any tribunal for any receiver or any trustee of such Covered Person or any
     substantial part of its property; (iv) commences any proceeding relating
     to such Covered Person under any reorganization, arrangement, readjustment
     of debt, dissolution or liquidation law or statute of any jurisdiction,
     whether now or hereafter in effect; (v) has commenced against it any such
     proceeding which remains


                                      41
<PAGE>   43


     undismissed for a period of thirty (30) days, or by any act indicates its  
     consent to, approval of, or acquiescence in any such proceeding or the
     appointment of any receiver of or any trustee for it or of any substantial
     part of its property, or allows any such receivership or trusteeship to
     continue undischarged for a period of thirty (30) days; or (vi) takes any
     corporate action to authorize any of the foregoing.

           18.1.10  JUDGMENTS; ATTACHMENT; ETC.  Any one or more judgments or 
     orders is entered against a Covered Person or any attachment or other levy 
     is made against the property of a Covered Person with respect to a claim
     or claims involving in the aggregate liabilities (not paid or fully
     covered by insurance, less the amount of reasonable deductibles in effect
     on the Execution Date) in excess of [$25,000], becomes final and
     non-appealable or if timely appealed is not fully bonded and collection
     thereof stayed pending the appeal.

           18.1.11  PENSION BENEFIT PLAN TERMINATION, ETC.  Any Pension Benefit 
     Plan termination by the PBGC or the appointment by the appropriate United
     States District Court of a trustee to administer any Pension Benefit Plan
     or to liquidate any Pension Benefit Plan; or any event which constitutes
     grounds either for the termination of any Pension Benefit Plan by PBGC or
     for the appointment by the appropriate United States District Court of a
     trustee to administer or liquidate any Pension Benefit Plan shall have
     occurred and be continuing for thirty (30) days after Borrower has notice
     of any such event; or any voluntary termination of any Pension Benefit
     Plan which is a defined benefit pension plan as defined in Section 3(35)
     of ERISA while such defined benefit pension plan has an accumulated
     funding deficiency, unless Lender has been notified of such intent to
     voluntarily terminate such plan and has given its consent and agreed that
     such event shall not constitute a Default; or the plan administrator of
     any Pension Benefit Plan applies under Section 412(d) of the Code for a
     waiver of the minimum funding standards of Section 412(1) of the Code and
     Lender believes that the substantial business hardship upon which the
     application for such waiver is based could subject any Covered Person or
     ERISA Affiliate to a liability in excess of $25,000.

           18.1.12  LIQUIDATION OR DISSOLUTION.  A Covered Person files a       
     certificate of dissolution under applicable state law or is liquidated or
     dissolved or suspends or terminates the operation of its business, or has
     commenced against it any action or proceeding for its liquidation or
     dissolution or the winding up of its business, or takes any corporate
     action in furtherance thereof; provided, however, that such actions in
     furtherance of a plan whereby the assets of such Covered Person are
     acquired by another Covered Person shall not be an Event of Default.

           18.1.13  SEIZURE OF ASSETS.  All or any part of the property of      
     Borrower is nationalized, expropriated or condemned, seized or otherwise
     appropriated, or custody or control of such property or of Borrower shall
     be assumed by any Governmental Authority or any court of competent
     jurisdiction at the instance of any Governmental Authority, except where
     contested in good faith by proper proceedings diligently pursued where a
     stay of enforcement is in effect.

           18.1.14  RACKETEERING PROCEEDING.  There is filed against Borrower   
     any civil or criminal action, suit or proceeding under any federal or
     state racketeering statute


                                      42
<PAGE>   44


     (including, without limitation, the Racketeer Influenced and Corrupt
     Organization Act of 1970), which action, suit or proceeding is not
     dismissed within 120 days and could result in the confiscation or
     forfeiture of any material portion of the Collateral.

           18.1.15  LOAN DOCUMENTS; LIENS.  For any reason other than the 
     failure of Lender to take any action available to it to maintain 
     perfection of the Security Interests created in favor of Lender pursuant
     to the Loan Documents, any Loan Document ceases to be in full force and
     effect or any Security Interest with respect to any portion of the
     Collateral intended to be secured thereby ceases to be, or is not, valid,
     perfected and prior to all other Security Interests (other than the
     Permitted Liens) or is terminated, revoked or declared void or invalid.

           18.1.16  LOSS TO COLLATERAL.  Any loss, theft, damage or destruction
     of any item or items of Collateral occurs which (i) materially and 
     adversely affects the operation of Borrower's business; or (ii) is
     material in amount and is not adequately covered by insurance.

           18.1.17  MATERIAL ADVERSE EVENT.  There occurs any material adverse  
     change in Borrower's property, business, operation, or condition
     (financial or otherwise), or there occurs any event which has or will have
     a Material Adverse Effect. 

     18.2  CROSS-DEFAULT.  Any Event of Default under this Agreement will 
constitute an event of default under any other agreement of Borrower with       
Lender and under any evidence of Indebtedness of Borrower held by Lender,
whether or not such is an event of default specified therein.

     18.3  RIGHTS AND REMEDIES IN THE EVENT OF DEFAULT.

           18.3.1 TERMINATION OF COMMITMENTS. Upon an Event of Default 
     described in Section 18.1.9, the Commitments shall be deemed canceled.  
     Upon any other Event of Default, and at any time thereafter, Lender may
     cancel the Commitments.  Such cancellation may be without demand or notice
     of any kind, which Borrower expressly waives.


           18.3.2  ACCELERATION. Upon an Event of Default described in Section
     18.1.9, all of the outstanding Loan Obligations shall automatically become
     immediately due and payable.  Upon any other Event of Default, and at any 
     time thereafter, Lender may declare all of the outstanding Loan 
     Obligations immediately due and payable.  Such acceleration may be without
     demand or notice of any kind, which Borrower expressly waives.

           18.3.3  RIGHT OF SET-OFF. Upon the occurrence of any Event of 
     Default and at any time and from time to time thereafter, Lender is hereby 
     authorized, without notice to Borrower (any such notice being expressly
     waived by Borrower), to set off and apply against the Loan Obligations any
     and all deposits (general or special, time or demand, provisional or
     final) at any time held, or any other Indebtedness at any time owing by
     Lender to or for the credit or the account of Borrower, irrespective of
     whether or not Lender shall have made any demand under this Agreement or
     the Notes


                                      43
<PAGE>   45


and although such Loan Obligations may be unmatured.  The rights of Lender      
under this Section are in addition to other rights and remedies (including,
without limitation, other rights of set-off) which Lender may otherwise have.

           18.3.4  NOTICE TO ACCOUNT DEBTORS.  During the continuance of any 
     Default that is not waived in writing by Lender and after the occurrence   
     of any Event of Default that is not waived in writing by Lender, Lender
     may, without prior notice to Borrower, notify any or all Account Debtors
     that the Accounts have been assigned to Lender and that Lender has a
     security interest therein, and Bank may direct, or Borrower, at Bank's
     request, shall direct, any or all Account Debtors to make all payments
     upon the Accounts directly to Bank.  Bank shall furnish Borrower with a
     copy of any such notice issued by Bank promptly after notifying such
     Account Debtors.

           18.3.5  ENTRY UPON PREMISES AND ACCESS TO INFORMATION.  Upon an 
     Event of Default and acceleration of the Loan Obligations as provided
     herein, and at any time thereafter:  Lender may (i) enter upon the
     premises leased or owned by Borrower where Collateral is located (or is
     believed to be located) without any obligation to pay rent to Borrower, or
     any other place or places where Collateral is believed to be located, (ii)
     render Collateral usable or saleable, (iii) remove Collateral therefrom to
     the premises of Lender or any agent of Lender for such time as Lender may
     desire in order effectively to collect or liquidate Collateral; (iv) take
     possession of, and make copies and abstracts of, Borrower's original books
     and records, obtain access to Borrower's data processing equipment,
     computer hardware and software relating to any of the Collateral and use
     all of the foregoing and the information contained therein in any manner
     Lender deems appropriate in connection with the exercise of Lender's
     rights; and (v) notify postal authorities to change the address for
     delivery of Borrower's mail to an address designated by Lender and to
     receive, open and process all mail addressed to Borrower.

           18.3.6  SECURED PARTY RIGHTS.  Upon an Event of Default and 
     acceleration of the Loan Obligations as provided herein, and at any time 
     and from time to time thereafter:

                 18.3.6.1  Lender may exercise any or all of its rights under 
           the Security Documents, as a secured party under the UCC and any 
           other applicable Law; and

                 18.3.6.2  Lender may sell or otherwise dispose of Collateral 
           at public or private sale in a commercially reasonable manner (ten   
           days notice of a public or private sale being deemed and agreed by
           Borrower to be reasonable), which sale Lender may postpone from time
           to time by announcement at the time and place of sale stated in the
           notice of sale or by announcement at any adjourned sale without
           being required to give a new notice of sale, all as Lender deems
           advisable, for cash or credit; provided, however, that Lender may
           become the purchaser at any such sale if permissible under
           applicable Law and Lender may, in lieu of actual payment of the
           purchase price, offset the amount thereof against Borrower's
           obligations owing to Lender; and Borrower agrees that


                                      44
<PAGE>   46


           Lender has no obligation to preserve rights to Collateral against
           prior parties or to marshal any Collateral for the benefit of any
           Person;

     In connection with the advertising for sale, selling or otherwise 
     realizing upon any of the Collateral securing the obligations of Borrower
     to Lender, Lender may use and is hereby granted a license to use, without
     charge or liability to Lender therefor, any of Borrower's labels, trade
     names, trademarks, trade secrets, service marks, patents, patent
     applications, licenses, certificates of authority, advertising materials,
     or any of Borrower's other properties or interests in properties of
     similar nature, to the extent that such use thereof is not prohibited by
     agreements under which Borrower has rights therein, and all of Borrower's
     rights under license, franchise and similar agreements shall inure to
     Lender's benefit.


           18.3.7  MISCELLANEOUS.  After the occurrence of an Event of Default 
     and at any time thereafter, Lender may exercise any other rights and 
     remedies available to Lender under the Loan Documents or otherwise
     available to Lender at law or in equity.

           18.3.8  APPLICATION OF FUNDS.  Any funds received by Lender with 
     respect to the Loan Obligations after any acceleration, including but not  
     limited to proceeds of Collateral, shall be applied as follows:  (i)
     first, to reimburse Lender for any amounts due to Lender under Sections
     19.8 and 19.9; (ii) second, to the payment of accrued and unpaid fees due  
     hereunder and all other amounts due hereunder (other than the Loans and
     interest accrued thereon); (iii) third, to the payment of interest accrued
     on the Loans; (iv) fourth, to the payment of the Loans, in such order as
     Lender determines in its sole discretion; and (v) fifth, to the payment of
     the other Loan Obligations. Any remaining amounts shall be paid to
     Borrower or such other Persons as shall be legally entitled thereto.


     18.4  BORROWER'S OBLIGATIONS.  Upon the occurrence of an Event of Default,
Borrower shall, if Lender so requests, assemble the Collateral and make it      
available to Lender at a place or places to be designated by Lender, reasonably
convenient to Borrower.

     18.5  LIMITATION OF LIABILITY; WAIVER. Lender shall not be liable to 
Borrower as a result of any commercially reasonable possession, repossession,   
collection or sale by Lender of Collateral; and Borrower hereby waives all
rights of redemption from any such sale and the benefit of all valuation,
appraisal and exemption laws.  If Lender seeks to take possession of any of the
Collateral by replevin or other court process, Borrower hereby irrevocably
waives (i) the posting of any bonds, surety and security relating thereto
required by any statute, court rule or otherwise as an incident to such
possession, (ii) any demand for possession of the Collateral prior to the
commencement of any suit or action to recover possession thereof, (iii) any
requirement that Lender retain possession and not dispose of any Collateral
until after trial or final judgment, and (iv) to the extent permitted by
applicable law, all rights to notice and hearing prior to the exercise by
Lender of Lender's right to repossess the Collateral without judicial process
or to replevy, attach or levy upon the Collateral without notice or hearing. 
Lender shall have no obligation to preserve rights to the Collateral or to
marshall any Collateral for the benefit of any Person.


                                      45
<PAGE>   47


     18.6  NOTICE.  Any notice of intended action required to be given by 
Lender, if given as provided in Section 19.1 at least 10 days prior to such
proposed action, shall be effective and constitute reasonable and fair notice 
to Borrower.

19   MISCELLANEOUS.

     19.1  NOTICES.  All notices, consents, requests and demands to or upon the
respective parties hereto shall be in writing, and shall be deemed to have been 
given or made when delivered in person to those Persons listed on the signature
pages hereof or when deposited in the United States mail, postage prepaid, or,
in the case of telegraphic notice, or the overnight courier services, when
delivered to the telegraph company or overnight courier service, or in the case
of telex or telecopy notice, when sent, verification received, in each case
addressed as set forth on the signature pages hereof, or such other address as
either party may designate by notice to the other in accordance with the terms
of this paragraph.  No notice given to or demand made on Borrower by Lender in
any instance shall entitle Borrower to notice or demand in any other instance.

     19.2  RIGHT TO CURE.  Lender may from time to time, in its sole discretion 
(but shall have no obligation to do so), for Borrower's account and at
Borrower's expense, pay (or make a Revolving Advance to pay) any amount or do
any act required of Borrower hereunder or requested by Lender to preserve,
protect, maintain or enforce the Loan Obligations, the Collateral or Lender's
Security Interests thereon, and which Borrower fails to pay or do, including,
without limitation, payment of any judgment against Borrower, insurance
premium, taxes or assessments, warehouse charge, finishing or processing
charge, landlord's claim, and any other Security Interest upon or with respect
to the Collateral.  All payments that Lender makes pursuant to this Section and
all out-of-pocket costs and expenses that Lender pays or incurs in connection
with any action taken by it hereunder shall be a part of the Loan Obligations,
the repayment of which shall be secured by the Collateral.  Any payment made or
other action taken by Lender pursuant to this Section shall be without
prejudice to any right to assert an Event of Default hereunder and to pursue
Lender's other rights and remedies with respect thereto.

     19.3  AMENDMENTS, WAIVERS AND CONSENTS.  No amendment to, waiver of, or 
departure from full compliance with any provision of this Agreement, or of any  
of the other Loan Documents, or consent to any departure by Borrower herefrom
or therefrom, shall be effective unless it is in writing and signed by
authorized officers of Borrower and the Lender; provided, however, that any
such waiver or consent shall be effective only in the specific instance and for
the purpose for which given.  No failure by Lender to exercise, and no delay by
Lender in exercising, any right, remedy, power or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise by Lender
of any right, remedy, power or privilege hereunder preclude any other exercise
thereof, or the exercise of any other right, remedy, power or privilege.

     19.4  RIGHTS NOT EXCLUSIVE.  Every right granted to Lender hereunder or 
under any other Loan Document or allowed to it at law or in equity shall be 
deemed cumulative and may be exercised from time to time.


                                      46
<PAGE>   48


     19.5  SURVIVAL OF AGREEMENTS.  All covenants and agreements made herein    
and in the other Loan Documents shall survive the execution and delivery of
this Agreement, the Notes and other Loan Documents and the making of every
Advance.  All agreements, obligations and liabilities of Borrower under this
Agreement concerning the payment of money to Lender, including but not limited
to Borrower's obligations under Sections 19.8 and 19.9, but excluding the 
obligation to repay the Loans and interest accrued thereon, shall survive the   
repayment in full of the Loans and interest accrued thereon, the return of the
Notes to Borrower and the termination of the Commitments. Subject to Section 8
of this Agreement, upon the payment in full of all Loan Obligations and the
termination of the Commitments, all Security Documents shall be deemed
terminated and shall be released of record by Lender.

     19.6  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and    
inure to the benefit of the parties hereto and all future holders of the Notes
and their respective successors and assigns, except that Borrower may not
assign, delegate or transfer any of its rights or obligations under this
Agreement without the prior written consent of Lender. With respect to
Borrower's successors and assigns, such successors and assigns shall include,
without limitation, any receiver, trustee or debtor-in-possession of or for
Borrower.  Lender shall have the right to assign its rights and to delegate its
obligations under the Loan Documents to any affiliate of such Lender that
assumes its obligations to make Loans to Borrower subject to the terms and
conditions herein, but such assignment and delegation should not relieve the
assigning and delegating Lender from its obligations hereunder.  Lender shall
have the right to assign its rights under the Loan Documents to any Federal
Reserve Bank, but without delegation of such Lender's obligations thereunder.

     19.7  PARTICIPATIONS.  Lender may in the ordinary course of its commercial
banking business and in accordance with applicable law grant participations to  
one or more banks or other financial institutions in any of the Loans.  For
this purpose, the Lender may disclose to a potential or actual participant any
information supplied to Lender by or on behalf of Borrower. Borrower hereby
acknowledges and agrees that every such participant has the same right of
set-off as does Lender under Section 18.3.3; provided, however, that all amounts
received by any such participant through the exercise of the right of set-off
in excess of its share of Loans as a participant shall be remitted to Lender.

     19.8  PAYMENT OF EXPENSES.  Borrower agrees to pay or reimburse Lender for
its costs and expenses incurred in connection with Lender's due diligence       
review, the negotiation and preparation of the Commitment Letter and the Loan
Documents, and the perfection of Lender's liens and security interests in the
Collateral, including but not limited to mortgagee's title insurance premiums,
recording and filing fees, appraisal fees, environmental consultant fees,
Lender's customary fees for honoring drawings on letters of credit, and all
reasonable attorneys' fees and all actual attorney's expenses advanced
(including but not limited to expenses for lien searches and filing charges,
facsimile and other electronic data transmissions, long-distance telephone
charges, courier and delivery charges and photocopying charges). 
Notwithstanding the foregoing, Borrower shall pay the first $25,000 of all such
costs and expenses, Lender shall pay the next $10,000 and Borrower and Lender
shall share equally all such costs thereafter. Further, if at any time or times
hereafter Lender engages legal counsel for advice or other representation to
enforce the rights of Lender against Borrower under the Loan Documents or in
connection with amendment, supplement, waiver, consent or subsequent closing
relating to any of the Loan Documents at the request


                                      47
<PAGE>   49


of Borrower or as a consequence of a Default or Event or Default, then all      
reasonable fees and all expenses advanced of such legal counsel and all
litigation costs, including costs incurred as a consequence of any proceedings
involving Borrower under the federal bankruptcy Code (if any) shall constitute
a part of the Loan Obligations and be payable by Borrower on demand.

     19.9  INDEMNITY.  Borrower shall pay, indemnify and hold harmless Lender   
and its directors, officers, employees, agents, and representatives (the
"Indemnified Parties") for, from and against, and promptly to reimburse the
Indemnified Parties for, any and all claims, damages, liabilities, losses,
costs and expenses (including, without limitations, reasonable attorneys' fees
and expenses and amounts paid in settlement) (the "Indemnified Liabilities")
incurred, paid or sustained by the Indemnified Parties in connection with,
arising out of, based upon or otherwise involving or resulting from any
threatened, pending or completed action, suit, investigation or other
proceeding by, against or otherwise involving the Indemnified Parties and in
any way dealing with, relating to or otherwise involving this Agreement, any of
the other Loan Documents, or any transaction contemplated hereby or thereby
(each a "Triggering Event"); provided, however, that Borrower shall have no
obligation to indemnify the Indemnified parties hereunder with respect to any
Indemnified Liabilities arising from the gross negligence, bad faith or willful
misconduct of any of the Indemnified Parties. Borrower shall pay, indemnify and
hold harmless the Indemnified Parties for, from and against, and promptly
reimburse the Indemnified Parties for, any and all claims, damages,
liabilities, losses, costs and expenses (including, without limitations,
reasonable attorneys' and consultant fees and expenses, investigation and
laboratory fees, removal, remedial, response and corrective action costs, and
amounts paid in settlement) incurred, paid or sustained by the Indemnified
Parties as a result of the manufacture, storage, transportation, release or
disposal of any Hazardous Waste on, from, over or affecting any of the
Collateral or any of the assets, properties, or operations of any Covered
Person or any predecessor in interest, directly or indirectly. Borrower shall
pay, indemnify and hold harmless the Indemnified Parties for, from and against,
and shall promptly reimburse the Indemnified Parties for, any and all claims,
damages, liabilities, losses, costs and expenses (including, without
limitations, reasonable attorneys' fees and expenses and amounts paid in
settlement) incurred, paid or sustained by the Indemnified Parties, arising out
of or relating to the Acquisition Agreement or Lender's enforcement of any of 
its rights with respect thereto.  The obligations of Borrower under this        
Section 19.9 shall survive the termination of the Commitments, the expiration of
letters of credit issued by Lender for the account of Borrower, the payment and
satisfaction of all of the Loan Obligations, and the release of the Collateral. 
To the extent that any of the indemnities set forth in this Section may be
unenforceable because it is violative of any law or public policy, Borrower
shall pay the maximum portion which it is permitted to pay under applicable
law.

     19.10 CHANGES IN ACCOUNTING PRINCIPLES.  If Borrower, at the end of its    
Fiscal Year and with the concurrence of its independent certified public
accountants, changes the method of valuing the Inventory of Borrower, or if any
other changes in accounting principles from those used in the preparation of
any of the Financial Statements are required by or result from the promulgation
of principles, rules, regulations, guidelines, pronouncements or opinions by
the Financial Accounting Standards Board or the American Institute of Certified
Public Accountants (or successors thereto or bodies with similar functions),
and any of such changes result in a change in the method of calculation of, or
affect the results of such calculation of, any of the financial covenants,
standards or terms found herein, then the parties hereto agree


                                      48
<PAGE>   50

to enter into and diligently pursue negotiations in order to amend such
financial covenants, standards or terms so as to equitably reflect such
changes, with the desired result that the criteria for evaluating the financial
condition and results of operations of Borrower shall be the same after such
changes as if such changes had not been made; provided, however, that until
such changes are made, all financial covenants herein and all the provisions
hereof which contemplate financial calculation hereunder shall remain in full
force and effect.

     19.11 LOAN RECORDS.  The date and amount of all Advances to Borrower and   
payments of amounts due from Borrower under the Loan Documents will be recorded
in the records that Lender normally maintains for such types of transactions. 
The failure to record, or any error in recording, any of the foregoing shall
not, however, affect the obligation of Borrower to repay the Loans and other
amounts payable under the Loan Documents.  Borrower shall have the burden of
proving that Lender's records are not correct. Borrower agrees that Lender's
books and records showing the Loan Obligations and the transactions pursuant to
this Agreement shall be admissible in any action or proceeding arising
therefrom, and shall constitute prima facie proof thereof, irrespective of
whether any Loan Obligation is also evidenced by a promissory note or other
instrument.  Lender will provide to Borrower a monthly statement of Advances,
payments, and other transactions pursuant to this Agreement.  Such statement
shall be deemed correct, accurate and binding on Borrower and an account stated
(except for reversals and reapplications of payments as provided in Sections 7
and 8 and corrections of errors discovered by Lender), unless Borrower notifies
Lender in writing to the contrary within thirty (30) days after such statement
is rendered.  In the event a timely written notice of objections is given by
Borrower, only the items to which exception is expressly made will be
considered to be disputed by Borrower.

     19.12 DRAFTING/NEGOTIATION.  Borrower and Lender represent one to the 
other that in the negotiation and drafting of this Agreement they have been     
represented by and have relied upon the advice of counsel of their choice. 
Borrower and Lender affirm that their counsel have both had substantial roles
in the drafting and negotiation of this Agreement and, therefore, this
Agreement shall be deemed drafted by both Borrower and Lender, and the rule of
construction to the effect that any ambiguities are to be resolved against the
drafter shall not be employed in the interpretation of this Agreement.

     19.13 OTHER SECURITY AND GUARANTIES. Lender may, without notice or demand
and without affecting Borrower's obligations hereunder, from time to time: (a)

                ATTACHMENT TO DOCUMENTS AND REQUIREMENTS LIST
                            OPINION SPECIFICATION


Legal opinion of corporate and local counsel to Borrower must be on firm
letterhead and together meet these requirements:

1.      Address to The Boatmen's National Bank of St. Louis at 75 West
        Lockwood, St. Louis, Missouri 63119.

2.      Refer to Loan Agreement and use its definitions.

3.      Give opinions on the subjects covered in all of the following example
        paragraphs:

        a.      Borrowers are corporations duly formed, validly existing and in
                good standing under the Laws of the State of their organization
                and are duly qualified and authorized to do business and are in
                good standing as foreign corporation in all states where the
                nature and extent of the business transacted by them or the
                ownership of their assets makes such qualification necessary,
                except where the failure to so qualify will not have a Material
                Adverse Effect.

        b.      Each Borrower has all requisite corporate power, authority and
                legal capacity and legal rights (a) to own, lease and operate
                its properties and assets and to carry on its business as now
                being conducted and (b) to execute, deliver and perform the
                terms of the Loan Documents to which it is a party.

        c.      All action on the part of each Borrower requisite for the
                execution, delivery and performance of the Loan Documents to
                which it is a party has been duly taken.

        d.      The execution, delivery and performance of the Loan Documents by
                each Borrower will not (a) violate, be in conflict with, result
                in the breach of, or constitute (with due notice or lapse of
                time, or both) a default under (i) Borrowers' Charter Documents,
                or (ii) any franchise, agreement, indenture, or other instrument
                to which a Borrower is a party or by which it or any of its
                property is bound or affected or (iii) any Law or other legal
                requirement applicable to a Borrower, or (b) result in the
                creation or imposition of a Security Interest of any nature
                whatsoever upon Borrowers' property or assets other than
                pursuant to the Loan Documents.
                                
        e.      Each Borrower has duly executed and delivered each of the Loan
                Documents to which it is a party and each such Loan Document
                constitutes the legal, valid and binding



                                      xi

                        
<PAGE>   77




             obligation of each Borrower enforceable against each Borrower
             in accordance with its terms.

        f.   Each Person who signed any Loan Document as an officer of a
             Borrower is duly authorized on behalf of a Borrower to execute,
             deliver and perform such document on behalf of such Borrower and
             is duly authorized to perform its obligations thereunder and to
             incur the obligations and make the representations, warranties and
             covenants made by it in such Loan Document.

        g.   Each Borrower has all certificates of authority, licenses,
             permits, qualifications and documentation to own, lease and
             operate its properties and to carry on its business as now being
             conducted, and is in compliance with all Laws applicable to the
             conduct of its business.

        h.   No consent, approval or other authorization of or by, or
             registration or filing with, any Governmental Authority or other
             Person is required in connection with the execution, delivery and
             performance by Borrower of the Loan Documents to which it is a
             party that has not already been obtained and a copy thereof
             delivered to Lender.

        i.   There are no actions, proceedings or investigations pending or
             threatened against any Borrower which might adversely affect the
             validity or enforceability of any of the Loan Documents, the
             ability of each Borrower to perform its obligations thereunder or
             which might adversely affect the business, operations, revenues,
             financial condition, property or business prospects of any
             Borrower.

        j.   The use of the proceeds of the Loans will not violate Regulations
             G, T, U or X of the Federal Reserve Board.

        k.   The Security Documents will create in favor of Lender, a legal,
             valid, and enforceable Security Interest in the personal property
             described therein as security for the Loan Obligations.  The
             Financing Statements are in proper form for recording or filing, as
             the case may be, in the public offices identified on Exhibit A to
             this letter and when the Financing Statements are filed in those
             public offices, the Security Interests of Lender or Administrative
             Agent, as the case may be, in the personal property described
             therein will be perfected to the extent such Security Interests
             may be perfected by filing.  To our best knowledge, Borrowers have
             no places of business other than as disclosed in the Loan
             Agreement.

                                     xii
<PAGE>   78
l.      The Missouri Deed of Trust and the Texas Deed of Trust are in proper
        form for recording and contains the terms and provisions necessary to
        enable Lender, following a default under such Deed of Trust, to
        exercise all of the remedies which are customarily available to a real
        estate lienholder under the Laws of the States of Missouri and Texas.  
        Assuming the proper recording of the Deed of Trust, the Deed of Trust
        will be a legal, valid and enforceable mortgage Security Interest on
        the Real Property Collateral in favor of Lender, to secure all of the
        Loan Obligations.

m.      Upon delivery to Lender of certificates identified in each Stock Pledge
        Agreement, Lender will have a valid, perfected and first priority
        security interest in and to all authorized and issued shares of each 
        Borrower to secure payment of all of the Loan Obligations.  All of the
        shares of the pledged stock are duly authorized, validly issued, fully
        paid and non-assessable.

n.      Neither the Deed of Trust, the Assignment of Rents nor the Financing
        Statements require the payment of any stamp tax or intangible tax or any
        recording, filing, privilege or other similar tax, fee or charge in
        connection with the execution, delivery, recordation or enforcement
        thereof, or any other state or local tax, fee or charge, except for 
        customary recording fees in connection with the indebtedness or
        transactions evidenced by the Loan Documents (other than income, 
        franchise, excess profits or capital stock taxes).

o.      If a court were to find that the Loan Documents are governed by, or are
        to be construed or interpreted in accordance with, the Laws of the
        State of Texas or California, the provisions of the Loan Documents 
        regarding interest required to be paid by Borrower will not violate any
        Law of the State of Texas or California that limits the amount of
        interest that may be charged or collected on a loan of money or the
        method by which such interest is computed.

p.      A Texas/California court of competent jurisdiction with the issues
        properly before it will honor the choice of law provisions included 
        in the Loan Agreement and the Security Documents except that a
        Texas/California court will apply Missouri law to questions regarding
        perfection by filing in the State of Texas/California of the Security
        Interest granted to Lender, in Personal Property Collateral pursuant to
        the Security Documents and the exercise in Texas/California of Bank's 
        remedies thereunder.

4.      Add appropriate exceptions limitations, all of which must be acceptable
        to Lender.

5.      Signature by a partner of the firm in his individual name or in the
        name of the firm.

     1.     Borrower shall maintain insurance, with insurance companies licensed

liability to third parties) and for such amounts as are customarily insured
against by other enterprises of like size and type as that of Borrower, 
including, without limitation:

            A.     Property damage insurance, which insurance shall include

Lenders from becoming a co-insurer of any loss under the insurance policies but
in any event in amounts equal to not less than the greater of (A) the actual
replacement value of the Collateral as determined by a qualified insurance
appraiser or insurer (selected by Borrower and approved by the Agents) not less
often than once every year expense of Borrower, and (B) the principal amount of
the Aggregate Loan.  Any such insurance may provide that the insurer is not
liable to the extent of the first $250,000 with the result that Borrower is its
own insurer to the extent of $250,000 of such risks.
        
            B.     Builder's risk insurance in an amount equal to the actual

            E.     Public liability insurance in accordance with customary 
insurance practices for similar operations with respect to the Collateral and
the business thereby conducted in a minimum amount of $12,000,000 which
insurance (A) will also provide coverage of Borrower's obligations to perform
its
        


                                      xvi
<PAGE>   82




     obligations under any agreement running to the benefit of the Lenders

     Borrower, and (C) shall not contain any provisions for deductible amount.

          F.   Excess coverage.

     insurable hazards as Agents from time to time may reasonably require.

     steam and pressure boilers and similar apparatus located on the Collateral
     from risks normally insured against under boiler and machinery policies
     and in amounts and with deductibles customarily obtained for similar
     business enterprises and in each case approved by Agents.

          I.   Workers' compensation insurance, disability benefits insurance
     and such other forms of insurance which Borrower is required by law to
     provide, covering loss resulting from injury, sickness, disability or
     death of the employees of Borrower or of any contractor or subcontractor
     performing work with respect to the Collateral.  Borrower shall require
     that all said contractors and subcontractors shall maintain all forms or
     types of insurance with respect to their employees required by law.

          J.   If the Collateral is located in a HUD identified flood hazard
     area, flood insurance in an amount equal to the greater of (a) the maximum
     amount of federal flood insurance available or (b) the lesser of (i) the
     amount of any mortgage encumbering the Collateral in favor of the Lender
     for the benefit of the Lenders, and (ii) $10,000,000, with the first year
     premium thereon prepaid.

          K.   Such other insurance in such amounts and against such insurable
     hazards as Agents from time to time may reasonably require.

     2.   All insurance required above shall be procured and maintained in
financially sound and generally recognized responsible insurance companies
authorized to write such insurance in the State.

     3.   The insurance policies required above shall:

          A.   Designate (except in the case of Workers' Compensation

damage to any real property upon which Lender holds a mortgage or any tangible
personal property in which Lender holds a Security Interest (collectively, the
"Property") be endorsed and made payable to Lender and shall name Lender as
Loss Payee under the standard mortgagee clause;

        C.      Provide that there shall be no recourse against Lender for the
payment of premiums or commissions or (if such policies or binders provide for
the payment thereof) additional premiums or assessments;

        D.      Provide that in respect of the respective interests of Lender
in such policies, the insurance shall not be invalidated by any action or
inaction of Borrower, any subsidiary or any third party and shall insure Lender
for the benefit of the Lenders regardless of and any losses shall be payable
notwithstanding:

                1.      Any act or negligence, including any breach of any
        condition, declaration or warranty contained in any such policy of
        insurance by Borrower, any subsidiary or any third party; 

                2.      The occupation, operation or use of the Property for
        purposes more hazardous than permitted by the terms of the policy;

        relating to the Property; or

                4.      Any change in the title to or ownership of all or any
        portion of the Property.

        E.      Provide that such insurance shall be primary insurance without
any right of contribution from any other insurance carried by Lender to the
extent that such other insurance provides Lender, as the case may be, with
contingent and/or excess liability insurance with respect to its respective
interest as such in the Property, and shall expressly provide that all
provisions thereof, except the limits of liability (which shall be applicable
to all insureds as a group) and liability for premiums (which shall be solely a
liability of Borrower) shall operate in the same manner as if there were a
separate policy covering such insured;

        F.      Provide that if the insurers cancel such insurance for any
reason whatsoever, or the same is allowed to lapse or expire, or there be any
reduction in amount, or any material change is made in the coverage, such

        thereunder against any party insured under such policy, and waives any

                             Disclosure Schedule

13.8 No Material Proceedings - There is an appeal in process due to the loss of
                               a patent and theft of trade secrets trial.  A 
                               bond has been posted for a counterclaim of court
                               and copying costs of the defendant.
                             - There is an ongoing IRS action involving the 
                               discussion of the classification of employees 
                               versus homeworkers.
                             - Lorvic Holding/The Lorvic Corporation is in an
                               ongoing IRS action involving the amortization
                               of Goodwill from prior years.  The estimated 
                               amount of liability has been put into an escrow
                               account with Boatmen's Bank.

13.10.5 Real Property - We discovered in 1991 that the septic system in 
                        Brownsville, TX had been contaminated from chemicals 
                        used in our plating operation.  We contracted with a
                        licensed firm to cleanup all hazardous waste in the
                        septic system and the surrounding ground with the job
                        completed in 1992.

to indemnify and hold harmless Buyer with respect to any such non-assumed
liabilities and obligations solely and to the limited extent, and in the manner
provided, in Section 8.08 hereof, provided, however, that during the period in
which Buyer is pursuing its indemnity rights against Seller, Buyer shall be
entitled to withhold, in amounts calculated pursuant to Section 5.2 of the
Assignment and Release Agreement (as defined below), all or a portion of the
Mendoza Payment and/or the Product Credit (as such terms are defined in the
Assignment and Release Agreement), in an amount equal to that amount being
sought from Seller pursuant to Buyer's indemnification rights, until such
rights against Seller have been exhausted.

Purchased Assets being sold pursuant to this Agreement, agrees to pay an amount

  1.04 Absolute Sale.  Seller agrees that the sale, conveyance, transfer and
delivery of the Purchased Assets to Buyer shall be free and clear of all title
defects, liabilities, obligations, liens, encumbrances, charges and claims of
any kind, except any liabilities and obligations expressly assumed by Buyer
pursuant to Section 1.02 hereof.

  1.05 Other Contracts.  This Agreement shall not constitute an agreement to
assign or sublicense, as the case may be, any contracts, leases, licenses,
agreements, bids, quotations or arrangements (for purposes of this Section 1.05
collectively called "contracts") if such attempted assignment or sublicense,
without the consent of the other party thereto, is not permitted as a matter of
law or in accordance with the terms of the contracts or would constitute a
breach of the contracts or would in any way impair the rights of Seller or
Buyer thereunder.  Seller will use its best efforts to obtain, or will assist
Buyer to obtain, such consents as may be necessary or appropriate to vest in
Buyer all of Seller's right, title and interest in all such contracts.  If such
consent is not obtained or if an assignment, attempted assignment or sublicense
is not so permitted or would be ineffective or would impair Buyer's rights
thereunder, Seller will cooperate with Buyer in any reasonable arrangement
designed to provide for Buyer the benefits under any such contracts provided,
however, that, except as disclosed on Schedule 1.05, Seller will obtain
consents to the assignment or sublicense of the contracts listed in Schedule
1.01(d) hereto (including those necessary for Buyer's continued operation of
the computer system and software used by Seller) on or prior to the Closing
Date.

  1.06 Bulk Sales Laws.  Seller and Buyer hereby waive compliance with the
provisions of any applicable bulk sales law; provided, however, that Seller
agrees to pay and discharge when due or to contest or litigate all claims of
creditors which are asserted against Buyer or the Purchased Assets by reason of
such noncompliance (other than with respect to the Assumed Liabilities), to
indemnify, defend and hold harmless Buyer from and against any and all such
claims in the manner provided in Section 8.07 hereof, and to take promptly all
necessary action to remove any lien or encumbrance which is placed on the
Purchased Assets by reason of such noncompliance.

agreements to which Seller is a party or by which Seller





                                      -10-
<PAGE>   18

is bound.  In the three years preceding the date of this Agreement, Seller has

the Closing Date ("Seller Employees") who are selected by Buyer in consultation
with Mendoza.  Schedule 7.01 contains a list of all Seller Employees as of

each bear their own costs and expenses incurred in connection with this
Agreement, the Related Agreements and the transactions contemplated hereby and

cause to be taken, all action, and to do, or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the sale of the Purchased Assets and the other
transactions contemplated by this Agreement and the Related Agreements.  From
time to time





                                      -19-
<PAGE>   27

after the date hereof (including after the Closing Date if requested), Seller
and its affiliates will, at their own expense and without further

reasonably request in order more effectively to vest in Buyer good title to the
Purchased Assets and to more effectively consummate the transactions
contemplated by this Agreement and the Related Agreements.

  8.03 Commissions and Fees.  Seller and Buyer each represents and warrants to
the other that no broker, finder, financial adviser or other person is entitled
to any brokerage fees, commissions or finder's fees in connection with the
transactions contemplated hereby by reason of any action taken by the party
making such representation.  Seller, on the one hand, and Buyer, on the other
hand, will pay to the other or otherwise discharge, and will indemnify and hold
the other harmless from and against, any and all claims or liabilities for all
brokerage fees, commissions and finder's fees (other than as described above)
incurred by reason of any action taken by such party.

  8.04 Sales, Transfer and Use Taxes.  The parties do not contemplate that any
sales, transfer or use taxes will be payable in connection with the
transactions contemplated by this Agreement and the Related Agreements.
However, to the extent such taxes are payable, all sales, transfer and use
taxes incurred in connection with this Agreement and the Related Agreements and
the transactions contemplated hereby and thereby will be borne by Seller, and
Seller will, at its own expense, file all necessary Tax Returns and other
documentation with respect to all such sales, transfer and use taxes, and, if
required by applicable law, both parties will join in the execution of any such
Tax Returns or other documentation.

  8.05 Nondisclosure.  Seller agrees not to use or disclose at any time after
consummation of the transactions contemplated hereby, except with the prior
written consent of an officer authorized to act in the matter by the Board of
Directors of Buyer, any trade secrets, proprietary information, or other
confidential information relating to designs, suppliers, subcontractors,
inventions, operations, marketing, bidding information, cost and pricing data,
master files or customer lists utilized by Seller in connection with its
business prior to the Closing or by Buyer or any of its affiliates (the "Buyer
Group"), or the skills, abilities and compensation of the Buyer Group's
employees, and all other similar information material to the conduct of the
Buyer Group's business, which is not presently generally known to the public;
provided, however, that this provision shall not preclude Seller from (i) the
use or disclosure of such information which presently is known generally to the
public or which subsequently comes into the public domain, other than by way of
disclosure in violation of this Agreement or in any other unauthorized fashion,
or (ii) disclosure of such information required by law or court order, provided
that prior to such disclosure required by law or court order the undersigned
will give Buyer three business days' written notice (or, if disclosure is
required to be made in less than three business days, then such notice shall be
given as promptly as practicable after determination that disclosure may be
required) of the nature of the law or order requiring disclosure and the
disclosure to be made in accordance therewith.

  and hold it harmless from any and all claims, liabilities, losses, damages,
  deficiencies, costs and expenses, of every kind, nature and description,
  fixed or contingent (including, without limitation, interest, penalties and
  counsel's fees and expenses) ("Losses"), asserted against, resulting to,
  imposed upon or incurred by Buyer, directly or indirectly, arising out of (i)
  any breach of any representation, warranty, covenant or agreement made by
  Seller under this Agreement, or (ii) any liability of Seller other than the
  Assumed Liabilities or any Environmental Claim.

   (b)   By Buyer.  Buyer agrees to save, defend and indemnify Seller against
  and hold it harmless from any and all Losses arising out of (i) any breach of
  any representation, warranty, covenant or agreement made by Buyer under this
  Agreement or (ii) any Assumed Liability.

  8.07 Defense of Claims.

   (a)   Should any claim, action or proceeding by or involving a third party
  arise after the Closing Date for which Seller or Buyer is liable under the
  terms of this Agreement, the party which is entitled to be indemnified with
  respect to such claim (the "Indemnified Party") shall notify the party who is
  liable therefor under the terms hereof (the "Indemnifying Party") within a
  reasonable time after such claim, action or proceeding arises and is known to
  the Indemnified Party, and if the Indemnifying Party shall admit in writing
  its indemnification obligation in respect thereof, the Indemnified Party
  shall give the Indemnifying Party a reasonable opportunity:

     (i)  to take part in any examination of the relevant books and records of
   the Indemnified Party;

     (ii) to conduct any proceedings or negotiations in connection therewith
   and necessary or appropriate to defend the Indemnified Party or prosecute
   any claim, action, counterclaim or other proceeding with respect thereto;

     (iii)  to take all other required steps or proceedings to settle or defend
   any such claim, action or proceeding; and

     (iv) to employ counsel reasonably acceptable to the Indemnified Party to
   contest any such claim, action or proceeding in the name of the Indemnified
   Party, or otherwise.

  The expenses of all proceedings, contests or lawsuits with respect to such
  claims or actions shall be borne by the Indemnifying Party.  If the
  Indemnifying Party wishes to assume the defense of any such  claim or action,
  it shall give written notice to the





                                      -21-
<PAGE>   29

  Indemnified Party admitting its indemnification obligation in respect thereof
  and stating that it intends to assume such defense within 15 days after
  notice from the Indemnified Party of such claim or action (unless the claim
  or action reasonably requires a response in less than 15 days after the
  notice is given to the Indemnifying Party, in which event it shall notify the
  Indemnified Party at least five days prior to such reasonably required
  response date), and the Indemnifying Party shall thereafter assume the
  defense of any such claim or liability, through counsel reasonably
  satisfactory to the Indemnified Party; provided that the Indemnified Party
  may participate in such defense at its own expense but, in any event, the
  Indemnifying Party shall have the right, as long as it is actively defending
  any claim or action, to control such defense.  The Indemnified Party shall
  afford the Indemnifying Party's counsel and other authorized representatives
  reasonable access during normal business hours to all relevant books,
  records, offices and other facilities and properties of the Indemnified
  Party, and to the personnel of the Indemnified Party, and shall otherwise use
  all reasonable efforts to cooperate with the Indemnifying Party, such counsel
  and such other authorized representatives in connection with the exercise of
  the rights of the Indemnifying Party pursuant to this Section 8.07.

   (b)   If the Indemnifying Party shall not assume the defense of, or if after
  so assuming it shall fail to actively defend, any such claim or action, the
  Indemnified Party may defend against any such claim or action in such manner
  as it may deem appropriate, and the Indemnified Party may settle such claim
  or litigation on such terms as it may deem appropriate, and the Indemnifying
  Party promptly shall reimburse the Indemnified Party for the amount of such
  settlement and for all expenses, legal and otherwise, reasonably and
  necessarily incurred by the Indemnified Party in connection with the defense
  against and settlement of such claim or action.  If no settlement of such
  claim or litigation is made, the Indemnifying Party shall satisfy any
  judgment rendered with respect to such claim or in such action, before the
  Indemnified Party is required to do so, and pay all expenses, legal or
  otherwise, reasonably and necessarily incurred by the Indemnified Party in
  the defense against such claim or litigation.

   (c)   If a judgment is rendered against the Indemnified Party in any action
  covered by the indemnification provisions hereof, or any lien attaches to any
  of the assets of the Indemnified Party, the Indemnifying Party immediately
  upon such entry or attachment shall pay such judgment in full or discharge
  such lien unless, at the Indemnifying Party's expense and direction, an
  appeal is taken under which the execution of the judgment or satisfaction of
  the lien is stayed.  If and when a final judgment is rendered in any such
  action, the Indemnifying Party shall forthwith pay such judgment or discharge
  such lien before the Indemnified Party is compelled to do so.

  8.08 Set-Off of Claims.  Bio Dental and Mendoza each agrees that, to the
extent provided, respectively, in the Assignment and Release Agreement and the
Employment Agreement, Losses as to which Buyer is entitled to indemnification
hereunder which remain unsatisfied after Buyer has exhausted its remedies
against Seller, may be satisfied solely by reducing the amount of the remaining
credit for future purchases to which Bio Dental is entitled,





                                      -22-
<PAGE>   30

or the amount of the remaining Noncompete Payment (as such term is defined in
the Employment Agreement) otherwise payable to Mendoza, all as set forth in
Section 5.2 of the Assignment and Release Agreement, incorporated herein by
this reference.  Except as so provided in this Section 8.08, Bio Dental and
Mendoza shall not be otherwise responsible for such Losses.  In the event of
any such proposed set-off, the provisions of Section 8.07 hereof shall remain
in effect and shall apply to the resolution of any claim, action or proceeding
by or involving a third party and Bio Dental and Mendoza shall be deemed to be
the "Buyer" thereunder.  In such event, Bio Dental and Mendoza agree to use all
commercially reasonable efforts to cooperate with each other with respect to
any such claim, action or proceeding.

  8.09 Escrow.  Bio Dental agrees, to the extent provided in the Escrow
Agreement, to indemnify Buyer against Losses, asserted against, resulting to,
imposed upon or incurred by Buyer, directly or indirectly, arising out of (i)
any breach of any representation or warranty contained in Section 3.22 of this
Agreement, or (ii) out of any matter described in the EPA Letter.

  8.10 Maintenance of Insurance Policies.  Seller agrees to maintain the
insurance policies set forth on Schedule 8.10 hereto following the Closing
through March, 1997, naming Seller, Buyer and Bio Dental as additional
insureds.

  material breach in any of the representations, warranties or covenants of
  Seller herein or by Seller if prior to completion of the Closing there shall
  have been a material breach of any of the representations, warranties or
  covenants of Buyer contained herein; provided, however, that a party shall
  not be permitted to terminate this Agreement based upon its own breach.

be an inadequate remedy for breach of this Agreement and that the obligations
of the parties shall be specifically enforceable, but the availability of

                      ASSIGNMENT AND RELEASE AGREEMENT


  THIS ASSIGNMENT AND RELEASE AGREEMENT (this "Agreement") is made this 22nd
day of July, 1996 by and among BIO DENTAL TECHNOLOGIES CORPORATION, a
California corporation ("Bio Dental"), DENTICATOR INTERNATIONAL, INC., a
Missouri corporation ("DII"), DENTICATOR INTERNATIONAL, INC., a California
corporation (the "Predecessor") and YOUNG INNOVATIONS, INC., a Missouri
corporation ("Young").


                                   WITNESSETH

  WHEREAS, Bio Dental and the Predecessor are parties to that certain Exclusive
License Agreement dated March 31, 1991, as amended by the Extension and
Modification of Exclusive License Agreement dated April 1, 1994, and as further
amended on January 19, 1996 (the Exclusive License Agreement, and all
amendments thereto being collectively referred to as the "License Agreement");

  WHEREAS, Bio Dental, the Predecessor and Young have entered into that certain
Asset Purchase Agreement of even date herewith (the "Purchase Agreement")
wherein Young or DII shall purchase certain assets and assume certain
liabilities of the Predecessor; and

  WHEREAS, pursuant to the terms and conditions set forth in this Agreement,
Bio Dental will sell and convey all of Bio Dental's rights, privileges,
interests and claims under the License Agreement to DII, and shall release DII,
the Predecessor and Young, and their respective affiliates, from any claims,
liabilities, demands, causes of action or suits that Bio Dental or its
affiliates may have against such parties arising out of or in any way connected
with (i) the License Agreement, or (ii) any other agreement, contract,
arrangement, occurrence or transaction, whether written or oral, of any nature
whatsoever, between such parties, other than this Agreement, and DII and the
Predecessor will similarly release Bio Dental.

  NOW, THEREFORE, in consideration of the premises and the mutual
representations hereinafter set forth, the parties hereto hereby agree as
follows:


  1. PURCHASE OF RIGHTS; RELEASE OF CLAIMS.  Pursuant to the terms and
conditions contained herein, and to induce Young and DII to consummate the
transactions contemplated by the Purchase Agreement, Bio Dental hereby
transfers and conveys to DII all of the rights and interests of Bio Dental
under the License Agreement and Bio Dental hereby releases DII, the
Predecessor, Young and their respective officers, directors and subsidiaries
from any claims, liabilities or amounts owing to Bio Dental through the date
hereof arising out of or in any way connected with (i) the License Agreement,
or (ii) any other agreement, contract, arrangement, occurrence or transaction,
whether written or oral, of any nature whatsoever, between Bio Dental and the
Predecessor, other than (w) this Agreement, (x) the Purchase Agreement, (y)
other agreements and instruments entered into or executed pursuant to the
Purchase Agreement and (z) amounts owing by DII, the Predecessor or Young for
goods purchased from Bio Dental in the ordinary course of business.  Without
limiting the foregoing, Bio Dental hereby expressly acknowledges that upon full
execution of this Agreement, Bio Dental shall not have any rights in or receive
any royalties from DII's use of the name "Denticator" or the manufacture and
distribution of products of DII or the Predecessor.  The Predecessor and DII
each releases Bio Dental and its officers, directors and subsidiaries from any
claims, liabilities or amounts owing to DII through the date hereof arising out
of or in any way connected with (i) the License Agreement, or (ii) any other
agreement,

<PAGE>   2

contract, arrangement, occurrence or transaction, written or oral, of any
nature whatsoever, between Bio Dental and the Predecessor, other than (w) this
Agreement, (x) the Purchase Agreement, (y) other agreements and instruments
entered into or executed pursuant to the Purchase Agreement and (z) amounts
owing by Bio Dental to the Predecessor or DII for goods purchased from them in
the ordinary course of business.  Each of Bio Dental and the Predecessor
acknowledges that Bio Dental and the Predecessor have performed fully all of
their obligations under the License Agreement.

  2. PURCHASE PRICE; METHOD OF PAYMENT.  In consideration of the assignment of
rights and interests and the full release described in Section 1 above, and for
Bio Dental's non-compete agreement in Section 6, Young hereby makes the
following payments and provides the below-defined Product Credit:

     2.1   CASH PAYMENT.  Cash in the amount of Seven Million Four Hundred Forty
  Nine Thousand Eighty Seven and NO/100 Dollars ($7,449,087.00) paid herewith
  to Bio Dental.

     2.2   ESCROW PAYMENT.  Cash in the amount of One Hundred Thousand Dollars
  ($100,0000) paid to The Union Bank of California ("Escrow Agent") pursuant to
  an Escrow Agreement of even date herewith among Bio Dental, Young and Escrow
  Agent, said funds to be disbursed by the Escrow Agent according to the terms
  of the Escrow Agreement.

     2.3   PRODUCT CREDIT.  Young hereby grants a credit (the "Product Credit")
  to Bio Dental that may be applied by Bio Dental or its subsidiary The Supply
  House ("Supply House") (or any other subsidiary of Bio Dental) toward future
  purchases of products from Young or subsidiaries of Young.  The Product
  Credit shall be in an amount equal to the aggregate amounts owing to Bio
  Dental by the Predecessor at the Closing Date (as defined in the Purchase
  Agreement), which amounts shall be calculated (i) according to the terms of
  the License Agreement, and (ii) consistent with the calculation of the
  amounts owing by the Predecessor to Bio Dental as of March 31, 1996.  The
  Product Credit and Mendoza Payment (as defined in Section 5.2 below) will,
  however, be reduced, by a ratio of fifty percent (50%) against the Product
  Credit and fifty percent (50%) against the Mendoza Payment, by the amount (if
  any) by which the Net Working Capital (as defined below) of the Predecessor
  as reflected on the balance sheet of the Predecessor as at the Closing Date
  (the "Closing Balance Sheet") is less than $471,783.00 (the Net Working
  Capital of the Predecessor at March 31, 1996).  For purposes of this
  provision, the term Net Working Capital means the difference between the
  current assets and the current liabilities of the Predecessor reflected on
  its balance sheet, adjusted, however, to (i) delete from such balance sheet
  all amounts owed by Bio Dental to the Predecessor or by the Predecessor to
  Bio Dental except amounts owing for goods purchased in the ordinary course of
  business, and (ii) include in current liabilities all outstanding
  indebtedness (whether short-term or long-term) of Seller to Bank of
  California.  The Closing Balance Sheet will be prepared by Young and the
  Predecessor in accordance with generally accepted accounting principles on a
  basis consistent with the preparation of the balance sheet of the Predecessor
  as at March 31, 1996.

   Bio Dental shall be provided reasonable access to the accounting records,
  supporting schedules and documents of the Predecessor.  Bio Dental may review
  the closing financial statements of the Predecessor, including adjustments
  and reserves, allowances or accrued liabilities of any kind.  If Bio Dental,
  after reviewing the financial statements, corresponding accounting records,
  supporting schedules and/or documents of the Predecessor, disagrees with any
  item or adjustment, Bio Dental shall submit in writing its disagreement to
  Young.  Young shall review the facts and circumstances of the disagreement
  and shall render a binding decision on the disagreement within fifteen (15)
  business days.



                                     -2-

<PAGE>   3


  3. APPLICATION OF PRODUCT CREDIT.  Purchases by Bio Dental or Supply House
(or any other subsidiary of Bio Dental) from Young or its affiliates or
subsidiaries will be applied against the Product Credit at the prevailing
prices in effect at the time of the purchases.  Young shall provide to Bio
Dental (i) written confirmation acknowledging application of all or a portion
of the Product Credit to a specific purchase order, and (ii) quarterly written
notification regarding the outstanding remaining balance of the Product Credit.

  4. LIMITATION ON PRODUCT CREDIT.  Use of all or a portion of the Product
Credit shall not be permitted in an amount by which all shipments exceed in any
month $55,000, which is the approximate average historical monthly shipments
level to Bio Dental and Supply House from Young and its subsidiaries over the
twelve (12) month period ended March 31, 1996; provided, however, that to the
extent that the application of the Product Credit by Bio Dental, Supply House
and other subsidiaries of Bio Dental is in the aggregate below such amount for
any month, application of the Product Credit may exceed such amount by the
amount of such difference in a subsequent month.  For any such shipments to
which the Product Credit cannot be applied because of the foregoing limits, the
standard wholesale terms and conditions of Young or its subsidiary with which
the order is placed shall apply.  The Product Credit shall not include freight,
insurance and other charges.

  5. REDUCTION IN PRODUCT CREDIT FOR INDEMNIFICATION.

   5.1   EVENT OF REDUCTION.  In the event that Young or a subsidiary of Young
  is entitled to indemnification against Losses (as defined therein) pursuant
  to Section 8.06 of the Purchase Agreement (the "Indemnification Amount"),
  Young shall have the right to reduce the then existing amount of the Product
  Credit by an amount calculated pursuant to Section 5.2 hereof.  Young shall
  also have the right to set off against the Product Credit any amounts owing
  to Young or its subsidiaries by Bio Dental or its subsidiaries.  In the event
  that Young exercises such right of set-off, Young shall provide written
  notification to Bio Dental of such action, and of the amount of such set-off.

   5.2   CALCULATION OF AMOUNT OF SET-OFF.  If, at the time Young is entitled
  to reduce the Product Credit pursuant to Section 5.1, Jose L.  Mendoza
  ("Mendoza") is still entitled to receive all or a portion of the Three
  Hundred Five Thousand Dollar ($305,000) payment described in Section 4.3 of
  the Employment and Noncompetition Agreement between Mendoza and a subsidiary
  of Young (the "Mendoza Payment"), then the Indemnification Amount shall be
  charged against the Product Credit and the Mendoza Payment in the ratio of
  seventy-five percent (75%) against the Product Credit and twenty-five percent
  (25%) against the Mendoza Payment.  The Indemnification Amount charged
  against (i) the Mendoza Payment shall not exceed the remaining Mendoza
  Payment and Mendoza's liability under this Agreement is limited to the
  remaining balance of the Mendoza Payment and (ii) the Product Credit shall
  not exceed the remaining Product Credit and Bio Dental's liability is limited
  to the remaining balance of the Product Credit.  If a portion of the
  Indemnification Amount still remains unsatisfied because the Mendoza Payment
  or the Product Credit has been fully satisfied, the remaining Product Credit
  or Mendoza Payment, respectively, as the case may be, shall be reduced by
  such amount.  At such time as the Product Credit or Mendoza Payment has been
  satisfied in full and Young remains entitled to set- off pursuant to Section
  8.08 of the Purchase Agreement, the remaining Mendoza Payment or Product
  Credit, respectively, as the case may be, shall be reduced by one hundred
  percent (100%) of the Indemnification Amount.

  6. NONCOMPETITION AGREEMENT.  For a period of two (2) years after the
effective date of this Agreement, Bio Dental shall not, and shall cause its
subsidiaries not to, within North America,





                                     -3-
<PAGE>   4

directly or indirectly, compete with Young or a subsidiary of Young in
manufacturing, licensing others to manufacture or selling under private label
any products, including prophy angles, which are the same, substantially
similar to or in direct competition with any products manufactured, sold or
distributed by the Predecessor prior to the Closing Date.  Notwithstanding the
above, Bio Dental and its subsidiaries shall be permitted to (i) sell and
distribute such products manufactured by others, but not those products listed
on Schedule 6.1 hereto, which are sold under the name of Bio Dental or of any
affiliate of Bio Dental unless and to the extent Bio Dental or its affiliate
sold such products under its name pursuant to private label arrangements in
effect prior to May 31, 1996; and (ii) sell and distribute such products
pursuant to arrangements with Young or any affiliates of Young.

  7. AMENDMENT AND MODIFICATION.  This Agreement may be amended, modified or
supplemented only by a written instrument executed by all of the parties
hereto.

  8. ASSIGNMENT.  Nothing contained in this Agreement shall be construed to
permit the assignment or delegation by any party hereto of any rights or
obligations hereunder and such assignment is expressly prohibited without the
written consent of the other parties hereto.  Notwithstanding the foregoing,
however, Bio Dental shall be permitted to assign its rights and obligations
hereunder to Zila, Inc. without the consent of the other parties hereto;
provided, however, that such assignment shall not relieve Bio Dental of any of
its obligations or duties hereunder nor shall such assignment affect Young's
rights hereunder including, without limitation, Young's right to reduce the
Product Credit pursuant to Section 5.1 hereof.  Notwithstanding any other
provision contained herein, Young and DII may pledge or grant a security
interest in any of their rights under this Agreement to any federal or state
chartered lending institution.

  9. SEVERABILITY.  If any term, covenant, or condition of this Agreement or
the application thereof to any person or circumstance shall be invalid or
unenforceable, the remainder of this Agreement and the application of any term
or provision to persons and circumstances other than those as to which it is
held invalid or unenforceable shall not be affected thereby, and all other
terms shall be valid and enforceable to the fullest extent permitted by law.

  10.  ENTIRE AGREEMENT.  This Agreement contains the entire agreement of the
parties hereto and it supersedes all prior agreements and understandings
between the parties hereto with respect thereto.

  11.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of
the State of California, without regard to conflict of law principles.

                               IV.  COMPENSATION

Two Hundred Fifty Dollars ($76,250) commencing on July 22, 1996, and thereafter
on October 22, 1996, January 22, 1997 and April 22, 1997.

                 4.3.1  REDUCTIONS TO NONCOMPETE PAYMENT.

                          4.3.1.1 REDUCTION PURSUANT TO INDEMNIFICATION CLAIMS.
                 In the event that Young Innovations, Inc., a Missouri
                 corporation ("Young") or an affiliate of Young, is entitled to
                 receive any amounts pursuant to the indemnification provisions
                 contained in that certain Asset Purchase Agreement dated July
                 22, 1996 by and among Employee, Young, Bio Dental Technologies
                 Corp. ("Bio Dental") and Denticator International, Inc. (the
                 "Indemnification Amount"), and Employee is still entitled to
                 receive all or a portion of the Noncompete Payment, then, to
                 the extent possible, twenty-five percent (25%) of the
                 Indemnification Amount shall be charged against the Noncompete
                 Payment.  The Indemnification Amount charged against the
                 Noncompete Payment, however, shall in no event exceed the
                 remaining unpaid balance of the Noncompete Payment and
                 Employee's liability under this Section 4.3.1.1 shall be
                 limited to the remaining unpaid balance of the Noncompete
                 Payment.

                          4.3.1.2  REDUCTION PURSUANT TO CHANGES IN NET WORKING
                 CAPITAL.  In the event that the Net Working Capital (as
                 defined below) of Denticator International, Inc., a California
                 corporation and the predecessor to Corporation ("Denticator"),
                 as reflected on the balance sheet of Denticator dated as of
                 July 22, 1996, is less than





                                      -2-
<PAGE>   3

                 $471,783.00 (the Net Working Capital of Denticator at
                 March 31, 1996), then, to the extent possible, fifty percent
                 (50%) of such difference shall be charged against the
                 Noncompete Payment.  For purposes of this provision, the term
                 Net Working Capital means the difference between the current
                 assets and the current liabilities of Denticator reflected on
                 its balance sheet, adjusted, however, to (i) delete from such
                 balance sheet all amounts owed by Bio Dental to Denticator or
                 by Denticator to Bio Dental except amounts owing for goods
                 purchased in the ordinary course of business, and (ii) include
                 in current liabilities all outstanding indebtedness (whether
                 short-term or long-term) of Seller to Bank of California.  The
                 amount charged against the Noncompete Payment pursuant to this
                 provision, however, shall in no event exceed the remaining
                 unpaid balance of the Noncompete Payment and Employee's
                 liability under this Section 4.3.1.2 shall be limited to the
                 remaining unpaid balance of the Noncompete Payment.

                           V.  BONUS STOCK; INSURANCE

         5.1  PERFORMANCE BASED BONUS STOCK; SHAREHOLDER AGREEMENT.  Pursuant 
to the terms of this Agreement, Employee shall be entitled to receive shares 
of the common stock (the "Bonus Stock") of Young with a value, in the
aggregate, of Eight Hundred Thousand Dollars ($800,000), with such valuation
being measured at the time Employee becomes entitled to receive the Bonus
Stock.  Prior to, and as a condition to, receiving the Bonus Stock, Employee
shall have executed a Shareholder Agreement (the "Shareholder Agreement") in
substantially the form of Exhibit B attached hereto.

         5.2  RECEIPT OF BONUS STOCK.  Employee shall be entitled to receive
the Bonus Stock on July 22, 1998 (the "Granting Date").

         5.3  VALUATION OF SHARES.  On the Granting Date, Corporation shall
perform a valuation in accordance with the following to determine the then
applicable value of the common stock of Young:

         (a)     If, on the Granting Date, the common stock of Young is listed
                 on a national securities exchange, the value of such common
                 stock shall be the closing price of the common stock of Young
                 on such exchange on the last trading date prior to the
                 Granting Date;

         (b)     If, on the Granting Date, the common stock of Young is quoted
                 on the National Association of Securities Dealers Automated
                 Quotation System ("NASDAQ"), the value of such common stock
                 shall be the last reported sale price prior to the Granting
                 Date;

         (c)     If, on the Granting Date, the common stock of Young is not
                 listed on a national securities exchange or quoted on NASDAQ,
                 but an active trading market exists with respect to such
                 common stock, the value of such common stock shall be the last
                 reported sale price in such market prior to the Granting Date;
                 or

         (d)     If neither (a), (b) or (c) above shall apply, the value of the
                 common stock of Young shall be determined as follows:

                        1.  By mutual agreement between Corporation and 
                 Employee as to the value of such common stock.





                                      -3-
<PAGE>   4

                          2.  If Corporation and Employee cannot reach mutual
                 agreement as to the value of the common stock of Young, then
                 an independent appraiser or valuation firm that is acceptable
                 to both Corporation and Employee shall be engaged to establish
                 the value of such common stock, and such valuation shall be
                 conclusive and binding upon Corporation and Employee.

                          3.  If Corporation and Employee cannot mutually agree
                 to the value of the common stock of Young or as to a mutually
                 acceptable appraiser or valuation firm, then Corporation and
                 Employee shall each select a qualified independent appraiser
                 or valuation firm, who in turn shall select a third
                 independent appraiser or valuation firm who shall be
                 responsible for determining the value of the such common
                 stock, and such valuation shall be conclusive and binding upon
                 Corporation and Employee.

         In the event that the value of the common stock of Young is determined
pursuant to Subparagraph (d) above, the costs of such valuation shall be
divided equally between Corporation and Employee.

         The determination of value of the common stock of Young pursuant to
subparagraphs (a), (b) and (c) above shall be made in good faith by Young's
Board of Directors, whose decision shall be final and binding on all parties.

         5.4 CALCULATION OF NUMBER OF SHARES.  Employee shall be entitled to
receive that number of shares of Bonus Stock (rounded down to the nearest whole
share with Employee receiving cash in lieu of any fractional share) as
determined by dividing Eight Hundred Thousand Dollars ($800,000) by the per
share price of common stock of Young as determined pursuant to Section 5.3.

         5.5  REPURCHASE BY CORPORATION.  Employee shall have the right to
require Corporation to repurchase from Employee up to forty percent (40%) of
the Bonus Stock (rounded down to the nearest whole share) distributed to
Employee on the Granting Date.  Employee shall provide written notice to
Corporation of Employee's intention to exercise such right at least ten (10)
days prior to the Granting date and such notice shall state what percentage of
the Bonus Stock that Corporation shall be required to repurchase.  Corporation
shall, within five (5) days after the completion of the valuation pursuant to
Section 5.3 hereof, repurchase such Bonus Stock.  The repurchase price of each
share of the Bonus Stock repurchased shall be the same price per share at which
the Bonus Stock was valued with respect to the Granting Date.  Upon such
repurchase, Corporation shall deliver to Employee its check for the repurchased
Bonus Stock, together with a certificate for the number of shares of Bonus
Stock to be received by Employee.

         5.6  RESTRICTIONS ON TRANSFER UNDER SHAREHOLDER AGREEMENT.  Employee 
recognizes that so long as Young is not required to file reports with
the Securities and Exchange Commission pursuant to Sections 13 or 15(d) of the
Securities and Exchange Act of 1934 (the "Exchange Act"), Employee shall be
subject to the terms and conditions of the Shareholder Agreement, and Employee
may not, except under certain circumstances, sell, transfer or otherwise
dispose of the Bonus Stock.

         5.7  STOCK UNREGISTERED; SECURITIES ACT MATTERS.  Employee has been
advised by Corporation that (i) the Bonus Shares have not been registered under
the Securities Act of 1933 (the "Securities Act"); (ii) the Bonus Shares may
not be sold, transferred or otherwise disposed of by Employee unless the offer
and sale of the Bonus Shares is subsequently registered under the Securities
Act or an exemption from such registration is available; (iii) there is not
currently any public market for the Bonus Shares; (iv) Rule 144 promulgated
under the Securities Act is not available to authorize





                                      -4-
<PAGE>   5

the sale by Employee at this time of any securities of Corporation including
the Bonus Shares and Corporation has made no representation as to the future
availability of such Rule for such a purpose; (v) when and if the Bonus Shares
may be disposed of without registration under the Securities Act in reliance on
Rule 144, such disposition can be made only in accordance with the terms and
conditions of such Rule; (vi) if the Rule 144 exemption is not available,
public offer or sale without registration will require the availability of an
exemption under the Securities Act; (vii) a restrictive legend in the form
heretofore set forth will be placed on the certificates representing the Bonus
Shares; and (viii) a notation will be made in the appropriate records of Young
indicating that the Bonus Shares are subject to restriction on transfer and, if
Young should at some time in the future engage the services of a stock transfer
agent, appropriate stop transfer restrictions will be issued to such transfer
agent with respect to the Bonus Shares.

         5.8  LEGENDS.  Any certificate representing Bonus Stock issued pursuant
to this Article V shall bear the following legends:

                 "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                 REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                 THE SECURITIES LAWS OF ANY STATE.  THEY MAY NOT BE SOLD,
                 OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
                 EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER
                 SAID ACT OR SECURITIES LAWS OR AN OPINION OF COUNSEL
                 SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT
                 REQUIRED."

                 "THIS CERTIFICATE MAY BE SOLD OR TRANSFERRED ONLY UPON
                 COMPLIANCE WITH THE TERMS AND CONDITIONS OF AN AGREEMENT DATED
                 __________, 1998, A COPY OF WHICH IS ON FILE WITH THE
                 SECRETARY OF THE CORPORATION."

         5.9  TERM LIFE INSURANCE.  Corporation shall purchase and keep in
effect until the Granting Date a term life insurance policy on the life of
Mendoza in the amount of $800,000 (the "Policy"), with the beneficiary to be
named by Mendoza; provided, that if Mendoza does not name a beneficiary,
Mendoza's spouse shall be the beneficiary.  Notwithstanding the foregoing
sentence, Corporation shall not be obligated to purchase the Policy if the life
of Mendoza is, for any reason, not insurable, or not insurable for premiums
less than $5,000 per year.

                              VI.  FRINGE BENEFITS

         Employee shall be entitled to participate with other employees of
Corporation, so long as Employee meets the applicable eligibility requirements,

Directors of Corporation shall determine from time to time within its
discretion.

                                 VII.  EXPENSES

         Reasonable expenses incurred and paid by Employee for promoting the
business of Corporation, including expenses for transportation, promotion,
entertainment, travel, telephone, and similar items, shall be subject to
reimbursement to the extent authorized for reimbursement by Corporation in
accordance with reasonable rules and regulations adopted by the Board of
Directors.  Such expenses as are so authorized for reimbursement shall be paid
for by Corporation or reimbursed to Employee upon Employee's presenting to
Corporation an itemized expense statement with respect thereto.

                            VIII.  DEATH OF EMPLOYEE

         In the event of Employee's death during the Term of this Agreement
(whether Employee is then actively engaged in the performance of services for
Corporation or is being compensated for disability), this Agreement shall
terminate immediately and Employee's estate shall be entitled to receive from
Corporation, in full satisfaction of Corporation's obligations to Employee, a
lump sum in an amount equal to the Base Pay due Employee up to the date of
Employee's death plus any portion of the Noncompete Payment that has not been
paid to Employee.  In the event of Employee's death prior to the Granting Date,
Employee's estate shall not be entitled to receive any portion of the Bonus
Stock or cash in lieu of the Bonus Stock.

                         IX.  TERMINATION OF EMPLOYMENT

         9.1  TERMINATION BY CORPORATION.  Corporation may terminate 
Employee's employment pursuant to this Agreement as follows:

                 A.  TERMINATION UPON DISABILITY.  The Board of Directors of
         Corporation may terminate Employee's employment hereunder if, as a
         result of Employee's incapacity resulting from physical or mental
         illness, Employee shall have been unable to perform his duties
         hereunder for a period of more than sixty (60) consecutive days or one
         hundred twenty (120) days, whether or not consecutive, during any
         twelve-month period.

                 B.  TERMINATION FOR CAUSE.  The Board of Directors of
         Corporation may terminate Employee's employment hereunder without any
         prior notice for "Cause" only upon commission by Employee of a crime
         of moral turpitude or the willful and continued failure by Employee to
         perform his duties to Corporation, including, without limitation, the
         commission by Employee of acts of gross negligence, dishonesty or
         misconduct, and/or failure to comply with his obligations under this
         Agreement (other than any such failure resulting from incapacity due
         to mental or physical illness) after a demand in writing for
         performance is delivered by the Board of Directors of Corporation,
         which demand specifically identifies the manner in which the Board
         believes that Employee has not substantially performed his duties to
         Corporation or complied with his obligations under this Agreement.

                 C.       EFFECT OF TERMINATION UNDER SUBSECTION (A).  In the
         event that Employee's employment terminates as a result of a
         disability pursuant to Subsection (A) above, Corporation shall pay to
         Employee or Employee's representatives, in full satisfaction of its
         obligations to Employee, a lump sum payment equal to the sum of (i)
         the Base Pay due Employee through the date of termination pursuant to
         Subsection (A) above, (ii) any portion of the Noncompete Payment that
         has not been paid to Employee and (iii) if such termination occurs 
         prior to the Granting Date, cash equal to $800,000 times a fraction, 
         the numerator of





                                      -6-
<PAGE>   7

         which is the number of days between the date of this Agreement and the
         date of such termination, and the denominator of which is 730.

                 D.       EFFECT OF TERMINATION UNDER SUBSECTION (B).  In the
         event that Employee's employment is terminated at any time by the Board
         of Directors of Corporation pursuant to Subsection (B) above,
         Corporation shall pay Employee, in full satisfaction of its obligations
         to Employee, all Base Pay due Employee up through the date such
         termination occurs and any portion of the Noncompete Payment that has
         not been paid to Employee.

         9.2  TERMINATION BY EMPLOYEE.  Employee may terminate Employee's
employment pursuant to this Agreement in the event that Corporation, during the
Term of this Agreement, has failed to perform its obligations hereunder, and
has not cured such failure within sixty (60) days after written notice by
Employee of such failure.

         In the event of any termination by Employee pursuant to this Section
9.2, or by Corporation other than pursuant to Article VIII or Section 9.1,
Corporation shall pay Employee as full satisfaction of its obligations to
Employee the Base Pay owed to Employee by Corporation through the date of such
termination plus a lump sum equal to the sum of the aggregate amount of (i)
Employee's Base pay for the lesser of (y) twelve (12) months, or (z) the
remainder of the Term as if the Agreement had not been so terminated; (ii) the
unpaid balance, if any, of the Noncompete Payment; and (iii) if such
termination occurs prior to the Granting Date, then either (y) cash, in lieu of
the Bonus Stock, in an amount equal to Four Hundred Thousand Dollars
($400,000), if such termination occurs during the first twelve (12) month
period of the Term, or (z) cash, in lieu of the Bonus Stock, in an amount equal
to Eight Hundred Thousand Dollars ($800,000), if such termination occurs during
the second twelve (12) month period of the Term.

         In the event of any termination by Employee other than pursuant to
this Section 9.2, Corporation shall pay Employee, in full satisfaction of its
obligations to Employee, all Base Pay due Employee up through the date of such
termination.

         9.3  COOPERATION BY EMPLOYEE.  Following any such notice of
termination, Employee shall fully cooperate with Corporation in all matters
relating to the winding up of Employee's pending work on behalf of Corporation
and the orderly transfer of any such pending work to such other employees of
Corporation as may be designated by Corporation; and to that end, Corporation
shall be entitled to such full-time or part-time services of Employee as
Corporation may reasonably require during all or any part of the period from
the time of giving any such notice until the effective date of such
termination.

                             X.  FILES AND RECORDS

         All files, records, reports and other documents concerning customers
of Corporation or any of its Affiliates (as such term is defined in Rule 12b-2
promulgated under the Exchange Act), including, without limitation, clients and
customers consulted, interviewed or served by Employee during the term of this
Agreement shall belong to and remain the property of Corporation or its
Affiliates.

                         XI.  CONFIDENTIAL INFORMATION

         11.1  NONDISCLOSURE BY EMPLOYEE.  Employee will not, except for the
purpose of benefiting Corporation or its Affiliates, during Employee's
employment with Corporation, and Employee will not under any circumstances at
any time after termination of Employee's employment, directly or

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (this "Agreement") is made this 22nd day of
July, 1996 by and among YOUNG INNOVATIONS, INC., a Missouri corporation
("Young"), BIO DENTAL TECHNOLOGIES CORP., a California corporation ("Bio
Dental"), and THE UNION BANK OF CALIFORNIA (the "Escrow Agent").

         WHEREAS, Young and Bio Dental are parties to that certain Asset
Purchase Agreement dated July 22, 1996 (the "Purchase Agreement"), pursuant to
which Young is purchasing substantially all of the assets of Denticator
International, Inc., a California corporation ("Denticator"), and pursuant to
which Bio Dental shall receive a portion of the consideration for selling and
conveying to Young, or a subsidiary of Young, all of Bio Dental's rights,
privileges, interests and claims under that certain Exclusive License Agreement
between Bio Dental and Denticator dated March 31, 1991, as amended.

         WHEREAS, pursuant to the Purchase Agreement, Young is required to
deposit with the Escrow Agent a portion of the consideration payable to Bio
Dental; and

         WHEREAS, the Escrow Agent has accepted such agency and agreed to hold
such funds in accordance with and subject to the terms of this Agreement.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties hereto agree as follows:

         1.      Establishment of Escrow Account; Purpose.

                 (a)  Establishment.  The Escrow Agent shall establish at its
         offices located at San Francisco, California an escrow account (the
         "Escrow Account") and shall cause all funds deposited into the Escrow
         Account to be held, invested and distributed in accordance with the
         terms of this Agreement.  The amount deposited into the Escrow
         Account, together with any proceeds of investments thereof, that may
         be held in the Escrow Account from time to time are hereinafter
         referred to collectively as "Escrow Funds."  The Escrow Agent shall
         keep appropriate records to reflect the current value from time to
         time of the Escrow Funds, including appropriate adjustments for
         disbursements and income earned or losses in respect thereof.

                 (b)  Purpose of Escrow Account.  The sole purpose of the
         Escrow Account is to provide a fund against which Young may assert
         claims for indemnification under Article VIII of the Purchase Agreement
         for (i) a breach by Seller of Seller's representations and warranties
         regarding certain environmental matters contained in Section 3.22 of
         the Purchase Agreement, and (ii) any Losses (as such term is defined
         in the Purchase Agreement) which arise out of the matters discussed in
         the letter from the Environmental Protection Agency to Denticator
         dated January 11, 1996.  Young shall not be permitted to make claims
         against the Escrow Account for any other matters.

         2.      Delivery of Escrow Funds.  At Closing (as defined in the
Purchase Agreement) Young shall deliver or cause to be delivered to the Escrow
Agent in accordance with the terms of the Purchase Agreement, cash in the
amount of One Hundred Thousand Dollars ($100,000) to be deposited into the
Escrow Account.





<PAGE>   2

         3.      Investment of Escrow Funds.  The Escrow Funds shall be
invested and reinvested by the Escrow Agent in such amounts and in such manner
as Bio Dental shall instruct the Escrow Agent from time to time in writing;
provided, however, that the Escrow Agent shall only invest the Escrow Funds in
those types of investments set forth on Exhibit A hereto.  If the Escrow Agent
has not received instructions from Bio Dental prior to fifteen (15) days of the
expiration of the term of any instrument in which Escrow Funds are invested,
the Escrow Agent shall invest such Escrow Funds in instruments of the same or
of a substantially similar type as the instruments set forth on Exhibit A
hereto.  Except as provided above, the Escrow Agent shall not be required to
invest any funds held hereunder unless requested by Bio Dental as provided
herein.

         4.      Release of Escrow Funds.  The Escrow Agent shall release the
Escrow Funds as follows:

                 (a)      Release Upon Mutual Written Instructions.  Young and
         Bio Dental may execute and deliver to the Escrow Agent written
         instructions ("Mutual Written Instructions"), and the Escrow Agent
         shall promptly upon receipt thereof disburse all or a portion of the
         Escrow Funds in the Escrow Account as provided in such Mutual Written
         Instructions.

                 (b)      Release Upon Young Claim Notice.  If Young shall have
         delivered to the Escrow Agent one or more written notices (each a
         "Young Claim Notice") stating that all or a portion of the Escrow
         Funds in the Escrow Account specified in such notice or notices should
         be released to Young because Young has made a claim against Bio Dental
         under the Purchase Agreement for such amount or amounts, the Escrow
         Agent shall retain such amount or amounts until the same are released
         pursuant to subsections (c) or (e) hereof.  Young shall deliver to Bio
         Dental a copy of each Young Claim Notice on or prior to the date of
         the delivery thereof to the Escrow Agent, and the Escrow Agent shall
         also deliver a copy thereof to Bio Dental promptly after receipt from
         Young.

                 (c)      Release to Young.  Unless the Escrow Agent shall have
         received a Bio Dental Hold Notice as defined in Section 4(d) below
         within thirty (30) days following receipt by the Escrow Agent of a
         Young Claim Notice, the Escrow Agent shall promptly thereafter release
         to Young such portion of the Escrow Account as is claimed by Young in
         such Young Claim Notice.

                 (d)      Bio Dental Hold Notice; Disputed Amounts.  If, within
         thirty (30) days of the Escrow Agent's receipt of a Young Claim Notice
         pursuant to Section 4(b) above, Bio Dental shall have delivered
         to the Escrow Agent written notice (a "Bio Dental Hold Notice")
         stating that all or a portion of the Escrow Account specified in such
         Young Claim Notice should not be released to Young, then the Escrow
         Agent shall not release such disputed amounts until the occurrence of
         one of the two events contemplated in Section 4(e) hereof.  Bio Dental 
         shall deliver to Young a copy of such Bio Dental Hold Notice on or 
         prior to the date of the delivery thereof to the Escrow Agent and 
         the Escrow Agent shall also deliver a copy of such Bio Dental Hold 
         Notice to Young promptly after receipt thereof from Bio Dental.

                 (e)      Release After a Bio Dental Hold Notice.  In the event
         that the Escrow Agent receives a Bio Dental Hold Notice as
         contemplated by Section 4(d) hereof, that portion of the Escrow Account
         that is in dispute as reflected in such Bio Dental Hold Notice shall
         be held by the Escrow Agent until the occurrence of one of the
         following events:





                                     -2-
<PAGE>   3

                          (1)  receipt by the Escrow Agent of Mutual Written
                 Instructions signed by Young and Bio Dental instructing the
                 Escrow Agent to release the disputed portion of the Escrow
                 Funds to such party or parties and in such amount or amounts
                 as is specified in such Mutual Written Instructions; or

                          (2)  receipt by the Escrow Agent of a written notice
                 (a "Certified Judgment Notice") from Young or Bio Dental
                 certifying that a final court judgment with respect to the
                 claim covered by Young Claim Notice is attached to such
                 Certified Judgment Notice, in which case the Escrow Agent
                 shall distribute the disputed portion of the Escrow Funds in
                 accordance with such judgment, unless within fifteen (15) days
                 of the Escrow Agent's receipt of a Certified Judgment Notice,
                 the Escrow Agent receives a written notice (an "Appeal
                 Notice") from the party not submitting such Certified Judgment
                 Notice stating that the judgment has or can and will be
                 appealed.  A party delivering a Certified Judgment Notice or
                 an Appeal Notice shall deliver to the other party hereto a
                 copy thereof on or prior to the date of delivery thereof to
                 the Escrow Agent, and the Escrow Agent shall also deliver a
                 copy of each Certified Judgment Notice or Appeal Notice to the
                 party which did not deliver the same promptly after the Escrow
                 Agent's receipt thereof.

                 (f)      Release Upon Termination of Agreement.  On July 22,
         1999 (the "Termination Date"), the Escrow Agent shall disburse to Bio
         Dental from the Escrow Account the amount, if any, by which the
         balance of the Escrow Account exceeds the aggregate amount of all
         Unresolved Claims (as defined below).  The Escrow Funds retained by
         the Escrow Agent shall be held solely for the purpose of satisfying
         the Unresolved Claims outstanding as of the Termination Date.  For
         purposes of this Agreement, the term "Unresolved Claims" shall mean
         all claims evidenced by a Young Claim Notice as to which the Escrow
         Agent has not received Mutual Written Instructions or a Certified
         Judgment Notice which is not the subject of an Appeal Notice, in
         either case directing release of Escrow Funds.  After the Termination
         Date, each time an Unresolved Claim is resolved as provided for
         herein, the amount of such Unresolved Claim shall be disbursed in
         accordance with the Mutual Written Instructions or the Certified
         Judgment Notice reflecting such resolution.

                 (g)      Release of Accrued Interest.  The Escrow Agent shall
         distribute to Bio Dental, within five (5) days after the end of each
         calendar quarter, an amount equal to 100% of all amounts earned on the
         Escrow Funds in the Escrow Account.  All earnings on the Escrow Funds
         prior to the time they are disbursed will, for all purposes of this
         Escrow Agreement, be treated as Escrow Funds, and will be released
         according to the terms of this Section 4.

                 (h)      Security Interests in Escrow Fund.

                          (1)  Except as expressly provided herein, neither
                 Young nor Bio Dental shall have any right, title or interest
                 in or possession of the Escrow Account.  Therefore, neither
                 Young nor Bio Dental shall have the ability to pledge, convey,
                 hypothecate or grant a security interest in the Escrow Account
                 or any portion thereof unless and until such assets have been
                 disbursed or are required to be disbursed to such party in
                 accordance with this Section 4, provided, however, that Young
                 may pledge or grant a security interest in any of its rights
                 under this Agreement to any federal or state chartered lending
                 institution.

                          (2)  Each of Young and Bio Dental acknowledges that
                 its interest in the Escrow Account is merely a contingent
                 right to payment from such Escrow Account.  Each of Young and
                 Bio Dental further acknowledges that neither a voluntary or
                 involuntary case under any applicable bankruptcy, insolvency
                 or similar law nor the appointment of a receiver, trustee,
                 custodian or similar official in respect of Young or Bio
                 Dental (any of which is referred to herein as a "Bankruptcy
                 Event") shall increase its respective interest in the Escrow
                 Account or affect, modify, convert or otherwise change the
                 contingent nature of its respective right to payment from the
                 Escrow Account in accordance with the terms of this Agreement.
                 Nonetheless:

                                  (i)  if a court of competent jurisdiction
                          determines that Young, upon the occurrence of a
                          Bankruptcy Event with respect to Young, has an
                          interest in the Escrow Account that is greater than a
                          contingent right to payment from the Escrow Account
                          payable only in accordance with the provisions of
                          this Section 4, then Young shall be deemed to have 
                          granted on the date hereof to Bio Dental a first 
                          priority security interest in, and pledged to Bio 
                          Dental all of its right, title and interest in 
                          the Escrow Account.  In such event, the
                          Escrow Agent shall be deemed to act as bailee on
                          behalf of Bio Dental in respect of Bio Dental's
                          security interest in Young's rights to the Escrow
                          Account.  The Escrow Agent shall, upon receipt of
                          indemnification satisfactory to it from Bio Dental
                          for its fees and expenses incurred in connection with
                          taking such actions, take all actions as may be
                          reasonably requested in writing of it by Bio Dental
                          to further perfect the security interest granted by
                          Young hereunder in the Escrow Account.  Such security
                          interest shall automatically be released with respect
                          to any funds properly distributed from the Escrow
                          Account pursuant to the terms of this Agreement; and

                                  (ii)  if a court of competent jurisdiction
                          determines that Bio Dental, upon the occurrence of a
                          Bankruptcy Event with respect to Bio Dental, has an
                          interest in the Escrow Account that is greater than a
                          contingent right to payment from the Escrow Account
                          payable only in accordance with the provisions of
                          this Section 4, then Bio Dental shall be deemed to 
                          have granted on the date hereof to Young a first 
                          priority security interest in, and pledged to 
                          Young all of Bio Dental's right, title and interest 
                          in the Escrow Account.  In any such event, the 
                          Escrow Agent shall be deemed to act as bailee on
                          behalf of Young in respect of Young's security
                          interest in Bio Dental's rights to the Escrow
                          Account.  The Escrow Agent shall, upon receipt of
                          indemnification satisfactory to it from Young for its
                          fees and expenses incurred in connection with taking
                          such actions, take all actions as may be reasonably
                          requested in writing of it by Young to further
                          perfect the security interest granted by Bio Dental
                          hereunder in the Escrow Account.  Such security
                          interest shall automatically be released with respect
                          to any funds properly distributed from the Escrow
                          Account pursuant to the terms of this Agreement.

                          (3)     The parties hereto agree and acknowledge that
                 the establishment and maintenance of the Escrow Accounts
                 hereunder are intended to constitute possession of the Escrow
                 Accounts for the purposes of perfecting the security interests
                 therein created hereunder.

         5.      Responsibility of the Escrow Agent.  The Escrow Agent accepts
the agency created by this Agreement upon the terms and conditions hereof and
undertakes to perform such duties and only such duties as are specifically set
forth herein.  No provision of this Agreement shall be construed to relieve the
Escrow Agent from liability for its own gross negligence or willful misconduct,
except that:

                 (a)      The duties and obligations of the Escrow Agent shall
         be determined solely by the express provisions of this Agreement, and
         no implied covenants, duties or obligations shall be read into this
         Agreement against the Escrow Agent nor shall the Escrow Agent be bound
         by the provisions of any other agreements between the other parties
         hereto beyond the specific terms hereof; the Escrow Agent shall not be
         liable for any action taken, suffered or omitted by it in good faith
         and reasonably believed by it to be authorized or within the
         discretion, rights, duties, privileges or powers conferred upon it by
         this Agreement; the Escrow Agent shall not be liable for any error of
         judgment made in good faith by a responsible officer or officers of
         the Escrow Agent, unless the Escrow Agent was grossly negligent in
         ascertaining the pertinent facts or in employing such officer or
         officers; and the Escrow Agent shall not be liable to any person with
         respect to any action taken, omitted or suffered to be taken by it in
         accordance with the provisions of this Agreement or in accordance with
         the written directions of Bio Dental or Young as provided herein or of
         a court of competent jurisdiction except in the case of the Escrow
         Agent's gross negligence or willful misconduct.

                 (b)      The Escrow Agent may act in reliance upon and be
         protected in acting or refraining from acting upon any instrument or
         signature believed to be genuine and may assume that any person
         purporting to give any writing, notice, advice or instruction in
         connection with the provisions hereof has been duly authorized to do
         so.

                 (c)      The Escrow Agent may consult with counsel, auditors
         and other experts and any opinion of counsel or written opinion of
         such auditors or other experts shall be full and complete
         authorization and protection with respect to any action taken or
         suffered or omitted by the Escrow Agent thereunder in good faith and
         in accordance with such opinion of counsel or opinion of such auditors
         or other experts within the area of their respective expertise.

                 (d)      The Escrow Agent may execute any of its powers or
         responsibilities hereunder and exercise any rights hereunder either
         directly or by or through its agents or attorneys.  Nothing in this
         Agreement shall be deemed to impose upon the Escrow Agent any
         liability to any other person as a result of any failure of the Escrow
         Agent to qualify to do business or to act as fiduciary or otherwise in
         any jurisdiction other than the jurisdiction of its formation.

                 (e)      No property held in escrow by the Escrow Agent
         hereunder shall be subject to any setoff, counterclaim, recoupment,
         lien or other right which the Escrow Agent may have against either of
         the other parties hereto or against any other person for any reason
         whatsoever.

                 (f)      If any dispute arises between Young and Bio Dental as
         to which of them is entitled to delivery of the disputed portion of
         the Escrow Funds, or if the Escrow Agent is uncertain as to its
         obligations hereunder, the Escrow Agent may, but shall not be
         obligated to, either (i) commence an interpleader action against Young
         and Bio Dental in a state or federal court located in Sacramento,
         California, and deposit the disputed Escrow Funds with such court,
         whereupon the Escrow Agent may apply to the court for an order
         discharging it from





                                     -5-
<PAGE>   6

         all further liability to any other party to this Agreement, or (ii)
         refrain from any action and continue to hold the disputed portion of
         the Escrow Funds pending a resolution of the dispute by either a court
         of competent jurisdiction or by a written agreement signed by Young
         and Bio Dental.  For the purposes of any action or proceeding
         contemplated by clause (i) above, each party hereby consents to the
         jurisdiction of said courts and agrees that service of process in any
         such action or proceeding may be made by certified or registered mail
         at the address for notices to such party provided in this Agreement.

         6.      Expenses; Indemnification.  Young and Bio Dental each agrees
to pay one-half of any fees or expenses charged by the Escrow Agent for its
services to be performed hereunder.  The Escrow Agent shall bill Bio Dental for
all such fees and expenses, and Bio Dental shall remit payment to the Escrow
Agent on behalf of the parties hereto.  Upon notice from Bio Dental, Young
shall immediately reimburse Bio Dental for Young's portion of such expenses and
fees.  In addition, Young and Bio Dental hereby agree jointly to indemnify the
Escrow Agent for, and to hold it harmless against, any loss, liability or
expense incurred without gross negligence or willful misconduct on the part of
the Escrow Agent, arising out of or in connection with its entering into this
Agreement and carrying out its duties hereunder, including the costs and
expenses of defending itself against any claim of liability.

         7.      Removal and Resignation.  The Escrow Agent may at any time be
removed by the written direction of Bio Dental and Young.  The Escrow Agent or
any successor escrow agent may at any time resign and be discharged of the
agency hereby created by giving written notice to each of Bio Dental and Young
specifying the date upon which it desires that such resignation shall take
effect.  Such removal or resignation shall take effect on the date specified in
the notice of removal or resignation, which date shall not be earlier than 60
days after the giving of the notice of removal or resignation unless a
successor escrow agent shall have been appointed pursuant to Section 8 hereof
and shall have accepted such appointment, in which event such removal or
resignation shall take effect immediately upon the acceptance by such successor
escrow agent.  Young and Bio Dental shall take prompt steps to have a successor
escrow agent appointed in the manner hereinafter provided.

         8.      Appointment of Successor Escrow Agent.  If at any time the
Escrow Agent shall resign or be removed or if at any time a vacancy shall occur
in the office of the Escrow Agent for any other cause, a successor escrow agent
shall be appointed by a written instrument executed by Young and Bio Dental and
delivered to the Escrow Agent and the successor escrow agent.  Upon acceptance
of said instrument by the successor escrow agent, the resignation or removal of
the Escrow Agent shall become effective and such successor escrow agent shall
become vested with all the rights, powers, duties and obligations of its
predecessor hereunder.  If no successor escrow agent shall have been appointed
at the effective date of resignation of the Escrow Agent, the Escrow Agent or
either other party hereto shall petition a court of competent jurisdiction for
the appointment of a successor and the Escrow Agent's duties shall be purely
ministerial until such appointment is effective.

         9.      Termination.  This Agreement shall terminate upon the release
of all Escrow Funds held in the Escrow Accounts hereunder pursuant to Section 4
hereof or upon written agreement of the parties hereto, which agreement, in the
case of the Escrow Agent, shall not be unreasonably withheld.

         10.     Notices.  All notices and other communications hereunder shall
be in writing and shall be deemed given if delivered personally or by facsimile
transmission, or mailed by overnight delivery service or by registered or
certified mail (return receipt requested), postage prepaid, to the parties at
