                               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 the Company 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 effected in the form of
a stock dividend on October 15, 1997 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, income from operations and net income (pro forma for 1992)
have grown at compound annual rates of 21.4%, 30.7% and 21.9%, 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 77.7% 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 flows. 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;
    
                                        3
<PAGE>   7
 
(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 popular price segment of the market, which the Company
traditionally had not targeted.
    
 
   
     Preventive dentistry, including regular professional cleaning and polishing
of teeth ("prophy" or "prophylaxis"), is effective in reducing 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 cost effectiveness of preventive dentistry, the
increasing proportion of dental services paid for by third parties and the
continued emphasis on infection control by dental professionals have led to and
will continue to result in an increase in the sales of preventive dental and
infection control products, particularly the Company's single-use products. 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.

(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 as adjusted 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; and (ii) 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 and 4,409,914
    weighted average shares outstanding for 1996 and the nine months ended
    September 30, 1997, respectively, 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 (net of underwriting discount and Offering
    expenses), 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) 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 $0.50 and
    $0.57 for the nine months ended September 30, 1996, and 1997, respectively,
    reflecting the elimination of interest expense, net of income taxes, of
    $441,000 for 1996 and $555,000 for 1997. Supplementary earnings per share
    assumes 4,450,210 and 4,409,914 weighted average shares outstanding for the
    nine months ended September 30, 1996 and 1997, respectively, plus 1,170,000
    and 1,460,000 shares, representing those shares of Common Stock sold at an
    assumed initial public offering price of $11.00 per share (net of
    underwriting discount and Offering expenses) and the application of the net
    proceeds therefrom sufficient to retire $11.5 million and $14.4 million of
    average outstanding borrowings for the nine months ended September 30, 1996
    and 1997, respectively.
    
 
   
(4) Until February 28, 1993, Young Dental had elected to be treated as an S
    Corporation for income tax purposes. 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 would have been $869,000 for 1992 and $368,000
    for 1993, assuming an income tax rate of 37.0%.
    
 
   
(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."

                                  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.
 
   
HIGHLY COMPETITIVE MARKETS
    
 
     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 17.3%, 16.8% and 9.8% of the Company's net sales for the
nine months ended September 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
26.6% and 26.8% of the Company's net sales for the nine months ended September
30, 1997 and for the year ended December 31, 1996, respectively. The Company has
no formal agreements with its distributors, which generally purchase products
from the Company by purchase order. 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, inability 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>   11
 
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."
 
   
ABILITY TO MANAGE 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 business, 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, Alfred E. Brennan, Senior Vice President and Chief Operating
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."

RISKS ASSOCIATED WITH 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 previously
associated with the 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 from 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.
 
                                        9
<PAGE>   13
 
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 currently maintains insurance coverage for such claims in the aggregate
amount of $5.0 million, 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. In 1996 and the first
nine months of 1997, respectively, the Company's expenditures for rubber
aggregated $184,000 and $152,000. The Company does not have formal agreements
with these suppliers and purchases rubber by purchase order. 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.
 
   
PENDING 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 Internal Revenue Service (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 petitions have been consolidated and are scheduled for trial
in January 1998. 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."
    
 
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 of $8.43 per share in the net tangible book value per share from the
assumed initial public offering price of $11.00. 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 $13.7
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 $8.5 million and bore interest at 8.2% per annum as of
September 30, 1997, and a revolving line of credit maturing on December 1, 1999,
which had an outstanding principal balance of $5.2 million and bore interest at
8.0% per annum as of September 30, 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 September 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

(1) The puttable Common Stock, all of which is held by employees of the Company,
    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
    Offering, such agreements will terminate and all outstanding shares of
    puttable Common Stock will be reflected in stockholders' equity. See
    "Certain Transactions."
 
   
(2) Does not include 350,000 shares reserved for issuance under the Company's
    1997 Stock Option Plan, of which options to purchase 226,000 shares of
    Common Stock will be issued immediately after the completion of the Offering
    at an exercise price equal to the initial public offering price. Also does
    not include an amount of shares not to exceed an aggregate value of $800,000
    based upon the market value of the Common Stock on July 22, 1998, that may

                                    DILUTION
 
   
     The Company's net tangible book value was $(5.2) million, or $(1.23) per
share, based on 4,208,300 shares of Common Stock outstanding as of September 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 September 30, 1997 would have been $16.5 million or $2.57 per share of
Common Stock. This represents an immediate increase in net tangible book value
of $3.80 per share to existing stockholders and an immediate dilution of $8.43
per share to new investors purchasing shares of Common Stock in the Offering.
The following table illustrates the per share dilution:

(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) 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 $0.50 and
    $0.57 for the nine months ended September 30, 1996, and 1997, respectively,
    reflecting the elimination of interest expense, net of income taxes, of
    $441,000 for 1996 and $555,000 for 1997. Supplementary earnings per share
    assumes 4,450,210 and 4,409,914 weighted average shares outstanding for the
    nine months ended September 30, 1996 and 1997, respectively, plus 1,170,000
    and 1,460,000 shares, representing those shares of Common Stock sold at an
    assumed initial public offering price of $11.00 per share (net of
    underwriting discount and Offering expenses) and the application of the net
    proceeds therefrom sufficient to retire $11.5 million and $14.4 million of
    average outstanding borrowings for the nine months ended September 30, 1996
    and 1997, respectively.
    
 
   
(3) Until February 28, 1993, Young Dental had elected to be treated as an S
    Corporation for income tax purposes. 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%.

on January 1, 1996: (i) the acquisition of Denticator and the incurrence of
indebtedness related thereto under the assumptions set forth in the accompanying
notes; and (ii) the sale of a portion of the Common Stock offered hereby and the
application of the net proceeds therefrom sufficient to retire $18.3 million of
borrowings. The unaudited pro forma financial information is not necessarily
indicative of the results of operations of the combined companies as they may be
in the future or as they might have been had the sale of Common Stock and the
acquisition been effective January 1, 1996. The unaudited pro forma financial

                    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, income from operations and net income (pro forma
for 1992) have grown to $21.6 million, $6.3 million and $3.3 million
respectively, in 1996 from $9.9 million, $2.2 million and $1.5 million,
respectively, in 1992, representing compound annual growth rates of
approximately 21.4%, 30.7% and 21.9%, respectively. 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. Typically, the Company's national promotions provide for a free
product for each purchase of a designated number of products. During such
national promotions, customers tend to increase their purchases, thus increasing
their inventories and reducing their purchases in subsequent quarters. 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. The
national promotion may also impact comparisons with comparable future quarters.
In addition, the Company offers annual rebate programs in which a portion of the
purchase price of products is rebated to customers who meet certain annual
volume purchase levels. In order to qualify for these rebate programs, customers
tend to increase purchases in the fourth quarter. The Company pays rebates for
the prior year in the first quarter of the subsequent 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 $7.6 million in cash and an
obligation to provide approximately $900,000 of Company products deliverable to
Bio Dental Technologies Corp. over approximately a 24 month period following the
acquisition. As of September 30, 1997, $267,000 of these products remained to be
delivered within the next 12 months. Denticator's line of
    
 
                                       19
<PAGE>   23
 
   
popular priced disposable prophy angles enabled the Company to extend its line
of Prophy Products, which the Company believes is 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. 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.
    
 
   
     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. Prior to its acquisition by the
Company, Lorvic's gross margin was higher than Young Dental's while Denticator's
gross margin was lower than Young Dental's primarily as a result of Denticator
outsourcing its injection molding needs. 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. 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.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
1996
    
 
   
     Net Sales. Net sales increased $3.1 million, or 20.7%, to $18.2 million in
1997 from $15.1 million in 1996. Sales of Prophy Products represented
approximately $2.7 million of the increase in net sales which was primarily
attributable to the Denticator acquisition. Sales of the Company's disposable
prophy angle products contributed approximately $2.4 million of the increase
with the remainder primarily attributable to increases in sales of prophy cups
and metal prophy angles. Additionally, sales of polishing pastes and powders
contributed approximately $100,000 and aspiration products contributed
approximately $83,000 to the increase.
    
 
   
     Gross Profit. Gross profit increased $2.2 million, or 25.6%, to $10.9
million in 1997 from $8.7 million in 1996. Gross margin increased to 59.7% of
net sales in 1997 from 57.4% in 1996. Gross profit benefited from increased
sales by Denticator, which represented approximately $1.9 million of such
increase. The Company's gross margin improved as a result of Denticator
initiating injection molding operations in April 1997.
    
 
   
     Selling, General, and Administrative Expenses. SG&A expenses increased $1.5
million, or 37.6%, to $5.5 million in 1997 from $4.0 million in 1996. As a
percent of net sales, SG&A expenses increased to 30.1% in 1997 from 26.4% in
1996. Denticator added $941,000 to 1997 SG&A as a result of its inclusion for
the full period of 1997. Approximately $225,000 of the increase attributable to
Denticator related to a deferred stock compensation agreement with its President
and Chief Executive Officer, which will end in July 1998. The Company also
incurred additional expenses of $316,000 related to a first quarter 1997
national disposable prophy angle promotion to dental professionals. In addition,
the Company added certain key personnel and accounting staff during 1997 in
preparation for and contemplation of going public.
    
 
   
     Income from Operations. Income from operations increased $713,000, or
15.3%, to $5.4 million in 1997 from $4.7 million in 1996.
    
 
   
     Interest Expense. Interest expense increased $195,000 to $895,000 in 1997
from $700,000 in 1996. The increase was due to the additional debt borrowed to
fund the acquisition of Denticator in July 1996.
    
 
   
     Other Expense (Income). Other expense (income) decreased $275,000 to
$(17,000) in 1997 from $258,000 in 1996 primarily due to inclusion in 1996 of a
write-off of deferred initial public offering costs.

     Provisions for Income Taxes. Provision for income taxes increased $349,000
for 1997 to $1.7 million from $1.4 million for 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 to Denticator's
President and Chief Executive Officer. SG&A also increased due to 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, which resulted in increased sales
and build-up of customer inventories 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, along with prophy cups and brushes, increased
approximately $331,000 in 1995 as compared to 1994. In addition, significant
sales increases
    
 
                                       22
<PAGE>   26
 
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 nine months of 1997, net cash flow from
operating activities was $3.0 million, compared to $4.5 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 $508,000 in the
first nine months of 1997, compared to $2.1 million 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 quarter 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 September 30, 1997, the outstanding balances under the
Credit Agreement aggregated $13.7 million, which balances will be repaid with a
portion of the net proceeds of the Offering. The Company's lending bank has
provided a letter which indicates its willingness to make available to the
Company, upon completion of the Offering, a five-year
    
 
                                       23
<PAGE>   27
 
   
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 and no significant changes in circumstances. The
bank's letter does not constitute a binding commitment to make the facility
available.
    
 
   
     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."
    
 
     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, income from operations and net income
(pro forma for 1992) have grown at compound annual rates of 21.4%, 30.7% and
21.9%, 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 77.7% 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 was incorporated in July 1995 to serve as the parent
corporation for Young Dental, founded at the turn of the century, and Lorvic and
its operating subsidiary, The Lorvic Corporation, founded in 1953; Lorvic was
acquired by Young Dental in May 1995. Denticator was acquired by the Company in
July 1996. 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.
    
 
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%.
    
 
   
     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. 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. For
example, 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.
    
 
   
     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 these regulations and guidelines have resulted in a
continued emphasis by dental professionals on the use of single-use products in
the dental office.
    
 
   
     The Company believes that the cost effectiveness of preventive dentistry,
the increasing proportion of dental services paid for by third parties and the
continued emphasis on infection control have led to and will continue to result
in an increase in the sales of preventive dental and infection control products,
particularly the Company's single-use products. Third party payors paid
approximately $16.1 billion in 1990 and $24.0 billion in 1995 for dental
services, which represented approximately 50.9% and 52.4%, respectively, of
total domestic dental products and services expenditures in those years. The
Company also believes demand will
    
 
                                       25
<PAGE>   29
 
   
continue to grow for preventive dental products, 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.
    
 
   
     The Company believes that the dental industry is presently undergoing
consolidation at three 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 for a number of reasons,
including the consolidation of distributors and dental service providers.
    
 
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.

     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.
 
                                       26

     Pursue Strategic Acquisitions. The Company aggressively pursues
acquisitions of complementary businesses, product lines and key technologies in
preventive dentistry and infection control. 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 acquisitions of dental product
companies 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 September 30, 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. International sales represented
approximately 4.6% of the Company's total net sales in 1996. 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, 77.7% of the Company's pro forma net sales were derived from the sale of
Prophy Products.
    
 
   
     Prophy Products. The Company believes it 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.
    
 
     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.
 
                                       27
<PAGE>   31
 
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
has no formal agreements with its distributors which generally purchase products
from the Company by purchase order. The Company believes these arrangements are
customary in the industry. 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.
    
 
   
     The 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
 
                                       29
<PAGE>   33
 
mail. To supplement its other marketing efforts, the Company provides product
samples to dental 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.
 
                                       30
<PAGE>   34
 
     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
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.

GOVERNMENT REGULATIONS
 
   
     The Company's products are subject to regulation by the FDA because they
meet the statutory definition for medical devices. The FDA has the authority to
regulate the design, manufacture, packaging, labeling and distribution of
medical devices.
    
 
   
     For a medical device to be properly in commercial distribution, it must (i)
qualify as a "preenactment" device, (ii) have in effect a premarket notification
(a "510(k)") or a premarket approval application, (iii) qualify for an exemption
from such requirements, or (iv) be so similar to a product with an effective
premarket notification that no separate filing is necessary. The Company has no
products that meet the criteria for a premarket approval application. Many of
the Company's products are preenactment devices, products that have been in
distribution since prior to May 28, 1976. Several other devices have effective
510(k)s or are so similar to products that do have them that filings are not
necessary under the FDA's current guidelines for filings involving product
modifications. The balance of the Company's medical devices have been exempted
from the need to file 510(k)s by regulations presently in effect.
    
 
   
     Products which the Company presently has in development may require a
510(k) before they can be sold. The FDA normally has 90 days to review the
510(k) and grant or deny clearance to market on the basis that it is
substantially equivalent to a device marketed before May 28, 1976.
Alternatively, the FDA may postpone a final decision and require the submission
of additional information, which may include clinical data. If additional
information is required, review and clearance of a 510(k) may be significantly
delayed. Certain devices under development may qualify to be exempt from the
510(k) premarket notification requirement and if so, the Company may proceed to
market without any submission to the FDA.
    
 
   
     The Company's products are generally subject to ongoing regulatory
oversight by the FDA to ensure compliance with regulatory requirements,
including, but not limited to, product labeling requirements and limitations,
including those related to promotion and marketing efforts, current good
manufacturing practice requirements, recordkeeping and medical device (adverse
reaction) reporting.
    
 
   
     The introduction and sale of the Company's products are also subject to
government regulation in the various foreign countries in which they are sold.
Some of these regulatory requirements are more stringent than those applicable
in the United States. Beginning in June 1998, all products imported into and
distributed in the European Common Market are required to have a CE mark and
meet the regulatory requirements of the European Economic Community. The Company
is presently taking all steps required for the certifications necessary to
comply with such requirements and expects to be approved prior to the June 1998
deadline.
    
 
   
     The Company also uses small amounts of hazardous substances in its
manufacturing processes. As a result, the Company is subject to a variety of
governmental regulations relating to the use, storage, discharge, handling and
disposal of toxic or other hazardous substances, chemicals, materials or waste.
The Company has engaged a third party contractor to handle the removal of such
hazardous substances.
    
 
   
LEGAL PROCEEDINGS
    
 
   
     For a description of legal proceedings in which the Company's subsidiaries
are parties, see "Risk Factors -- Pending Legal Proceedings."
    
 
     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.

STOCK OPTION PLAN
 
   
     The Company has adopted the 1997 Stock Option Plan (the "Option Plan") to

its subsidiaries as the Committee may select from time to time and those
non-employee directors of the Company as the Company's Board of Directors may
select from time to time.
    
 
   
     Unless otherwise determined by the Committee or provided in the stock
option agreement relating to a particular option, employee options will
terminate upon the participant's termination of employment to the extent not
then exercisable, and options that have become exercisable on or prior to the
date of termination of employment will terminate at the earlier of: (i) the
expiration date of the option; or (ii) where such termination is by the Company
for cause, as defined in the Option Plan, the time of such termination; or (iii)
where such termination occurs as a result of death or disability, one year after
termination of employment; or (iv) where such termination occurs other than as a
result of termination for cause or death or disability, three months after
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. Unless otherwise determined by the Committee, options granted
under the Option Plan will become exercisable in full in the
    
 
                                       35

event of a change in control, as defined in the Option Plan. All other terms,
including the time or times at which an option becomes exercisable, are
determined by the Committee in its discretion.

226,000 shares of Common Stock, all at an exercise price equal to the initial
public offering price of the Common Stock sold in the Offering. An option was
granted to Alfred E. Brennan for 60,000 shares of Common Stock as provided by
his employment agreement, to certain other officers and employees for a total of
156,000 shares of Common Stock, and to its two non-employee Directors for a
total of 10,000 shares of Common Stock. Mr. Brennan's option is immediately
exercisable as to 25% of the shares subject to option and becomes exercisable as
to an additional 25% on January 1 of each year from 1999 to 2001. Options
granted to the Company's non-employee Directors are immediately exercisable.
Each of the other options first becomes exercisable as to 25% of the shares

additional 25% on January 1 of each year from 2000 to 2002.

                              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 September 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 nine months ending
September 30, 1997, respectively, the Company paid an aggregate of $9,000,
$14,000, $10,000 and $10,000 to 3D for plastic resin prototyping services
provided to the Company. 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 nine months of 1997, respectively,
were $27,000, $38,000, $41,000 and $10,000. 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. Technologies purchases certain
products and components from the Company from time to time. Total amounts billed
to Technologies in 1994, 1995, 1996 and the nine months ending September 30,
1997, respectively, were $47,000, $15,000, $34,000 and $66,000. 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 and five other Denticator employees organized Hot Plastics
Technologies, Inc. ("HPT"), which performed injection molding for Denticator
between January and April, 1997. Mr. Mendoza held 75% 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.

Company will consist of 25,000,000 shares of Common Stock, par value $.01 per

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

Stock, or the perception that such sales could occur, could adversely affect the

     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
 
                                       40
<PAGE>   44
 
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

                    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.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Young Innovations, Inc. and
subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

     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

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. Estimated useful lives for buildings and improvements range from 15
to 39 years and for machinery and equipment from three to ten 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.
 
   
ADVERTISING COSTS
    
 
   
     Advertising costs are expensed when incurred.
    
 
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, 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.
 
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:

purchase price was financed through bank debt.
 
     In accordance with the Lorvic stock purchase agreement, the Company paid
part of the purchase price to various escrow funds totaling $2,350. The
representations and warranties made by the former stockholders of Lorvic for
which the general contingencies escrow fund has been established will survive
until May 5, 1997. The income tax contingencies amount of $900 will survive
until the dispute described in Note 18 is resolved and the remaining $500 will
survive until the applicable limitation periods have elapsed. The escrow funds
are maintained for the following matters:

     The Company generates trade accounts receivable in the normal course of
business. The Company grants credit to distributors throughout the world and

     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:

     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

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 $.57 (unaudited) for the year ended December 31, 1996, and nine months
ended September 30, 1997, respectively, reflecting the elimination of interest
expense, net of income taxes, of $614 for 1996 and $555 for the nine months
ended September 30, 1997. Supplementary earnings per share assumes 4,444,003 and
4,409,914 weighted average shares outstanding for 1996 and the nine months ended
September 30, 1997, respectively, plus 1,280,000 and 1,460,000 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 $14.4 million of average outstanding borrowings
for 1996 and the nine months ended September 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.

     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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     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.
 
     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 with cash up to 40% of
the stock at the last reported sale price on July 22, 1998 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 a liability of $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 owned
75% 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 petitions have been
consolidated and are scheduled for trial in January 1998. 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

                            YOUNG INNOVATIONS, INC.
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
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 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 15, 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 and non-employee directors
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.
Pursuant to the stock option plan, the Company has granted options to purchase
226,000 shares of Common Stock at an exercise price equal to the initial public
offering price. An option to purchase 60,000 shares of Common Stock has been
granted to one employee, is immediately exercisable as to 25% of the shares
subject to the option and will become exercisable as to an additional 25% on
January 1 of each year from 1999 to 2001. Options to purchase an aggregate of
10,000 shares of Common Stock have been granted to two non-employee Directors
and are immediately exercisable. Each of the other options first becomes
exercisable as to 25% of the shares subject to option on January 1, 1999 and
will become exercisable as to an additional 25% on January 1 of each year from
2000 to 2002.

             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

for $.01 per share. The difference between the fair market value, based on the

                    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 Corp. (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>

Fixed assets..............................................  $ 47,592
Inventories...............................................   535,139
Organization costs and goodwill...........................    17,838
                                                            --------
                                                            $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.
 
     No provision was made for current or deferred income tax expense for the
period from April 1, 1996, through July 22, 1996.

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 for $4,645 and $14,864, in cash, respectively, subject
to appropriate resale restrictions. None of the foregoing shares were registered
under the Securities Act. The Registrant believes that none of these
transactions involved a public offering, and all were exempt from registration
under the Securities Act pursuant to Section 4(2) thereof.

  As Representatives of the Several Underwriters
  Identified in Schedule I Annexed Hereto
c/o Robert W. Baird & Co. Incorporated

Ladies and Gentlemen:

  SECTION 1.  INTRODUCTORY.  Young Innovations, Inc., a Missouri

SHARES") of common stock, $.01 par value per share (the "COMMON STOCK"), to the
several underwriters identified in Schedule I annexed hereto (the
"UNDERWRITERS"), who are acting severally and not jointly.  In addition, the
Company has agreed to grant to the Underwriters an option to purchase up to
300,000 additional shares of Common Stock (the "OPTIONAL SHARES") as provided
in section 5 hereof.  The Firm Shares and, to the extent such option is
exercised, the Optional Shares are hereinafter collectively referred to as the
"SHARES."

  You, as representatives of the Underwriters (the "REPRESENTATIVES"),
have advised the Company that the Underwriters propose to make a public
offering of their respective portions of the Shares as soon hereafter as in
your judgment is advisable and that the public offering price of the Shares
initially will be $_____ per share.

  The Company hereby confirms its agreements with the Underwriters as
follows:

  SECTION 2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE
PRINCIPAL SHAREHOLDER.  The Company represents and warrants to, and agrees
with, the several Underwriters, and shall be deemed to represent and warrant to
the several Underwriters on each Closing Date (as hereinafter defined), that:

  (a)  Each of the Company and the subsidiaries of the Company that are listed
       on Exhibit 21.1 of the Registration Statement (as hereinafter defined)
       (individually, a
<PAGE>   2

       "SUBSIDIARY" and collectively, the "SUBSIDIARIES") has been duly
       incorporated and is validly existing as a corporation and in good
       standing under the laws of its jurisdiction of incorporation, with full
       corporate power and authority to own, lease and operate its properties
       and to conduct its business as presently conducted and described in the
       Prospectus (as hereinafter defined) and the Registration Statement; each
       of the Company and the Subsidiaries is duly registered and qualified to
       do business as a foreign corporation under the laws of, and is in good
       standing as such in, each jurisdiction in which such registration or
       qualification is required, except where the failure to so register or
       qualify would not have a material adverse effect on the condition
       (financial or other), business, property, net worth, results of
       operations or prospects of the Company and the Subsidiaries, taken as a
       whole ("MATERIAL ADVERSE EFFECT"); and no proceeding has been instituted
       in any such jurisdiction revoking, limiting or curtailing, or seeking to
       revoke, limit or curtail, such power and authority or qualification.
       Complete and correct copies of the articles of incorporation and
       by-laws, as amended or restated ("ARTICLES OF INCORPORATION" and
       "BY-LAWS," respectively), of the Company and each of the Subsidiaries as
       in effect on the date hereof have been delivered to the Representatives,
       and no changes thereto will be made on or subsequent to the date hereof
       and prior to each Closing Date.

  (b)  The shares of Common Stock issued and outstanding immediately prior to
       the issuance and sale of the Shares to be sold by the Company hereunder
       as set forth in the Prospectus have been duly authorized and validly
       issued, are fully paid and nonassessable and conform to the description
       thereof contained in the Prospectus and the Registration Statement.
       There are no preemptive, preferential or, except as described in the
       Prospectus, other rights to subscribe for or purchase any shares of
       Common Stock (including the Shares), and no shares of Common Stock have
       been issued in violation of such rights.  The Shares to be issued and
       sold by the Company to the Underwriters have been duly authorized and,
       when issued, delivered and paid for pursuant to this Agreement, will be
       validly issued, fully paid and nonassessable and will conform to the
       description thereof contained in the Prospectus and the Registration
       Statement.  The delivery of certificates for the Shares to be issued and
       sold by the Company hereunder and payment therefor pursuant to the terms
       of this Agreement will pass valid title to such Shares to the
       Underwriters, free and clear of any lien, claim, encumbrance or defect
       in title.  Except as described in the Prospectus, there are no
       outstanding options, warrants or other rights of any description,
       contractual or otherwise, entitling any person to be issued any class of
       security by the Company or any Subsidiary, and there are no holders of
       Common Stock or other securities of the Company or any Subsidiary, or of
       securities that are convertible or exchangeable into Common Stock or
       other securities of the Company or any Subsidiary, that have rights to
       the registration of such Common Stock or securities under the Securities
       Act of 1933, as amended, and the regulations

       thereunder (together, the "ACT") or the securities laws or regulations
       of any of the states (the "BLUE SKY LAWS").

  (c)  Except for the Subsidiaries, and as otherwise set forth in the
       Prospectus, the Company has no subsidiaries and does not own any equity
       interest in or control, directly or indirectly, any other corporation,
       limited liability company, partnership, joint venture, association,
       trust or other business organization.  The Company owns directly or
       indirectly all of the issued and outstanding capital stock of each
       Subsidiary, free and clear of any and all liens, claims, encumbrances or
       security interests, and all such capital stock has been duly authorized
       and validly issued and is fully paid and nonassessable.  There are no
       outstanding options, warrants or other rights of any description,
       contractual or otherwise, entitling any person to subscribe for or
       purchase any shares of capital stock of any Subsidiary.

  (d)  The Company has full corporate power and authority to enter into and
       perform this Agreement, and the execution and delivery by the Company of
       this Agreement and the performance by the Company of its obligations
       hereunder and the consummation of the transactions described herein,
       have been duly authorized with respect to the Company by all necessary
       corporate action and will not:  (i) violate any provisions of the
       Articles of Incorporation or By-laws of the Company or any Subsidiary;
       (ii) violate any provisions of, or result in the breach, modification or
       termination of, or constitute a default under, any provision of any
       agreement, lease, franchise, license, indenture, permit, mortgage, deed
       of trust, evidence of indebtedness or other instrument to which the
       Company or any Subsidiary is a party or by which the Company or any
       Subsidiary, or any property owned or leased by the Company or any
       Subsidiary, may be bound or affected; (iii) violate any statute,
       ordinance, rule or regulation applicable to the Company or any
       Subsidiary, or order or decree of any court, regulatory or governmental
       body, arbitrator, administrative agency or instrumentality of the United
       States or other country or jurisdiction having jurisdiction over the
       Company or any Subsidiary; or (iv) result in the creation or imposition
       of any lien, charge or encumbrance upon any property or assets of the
       Company or any Subsidiary.  No consent, approval, authorization or other
       order of any court, regulatory or governmental body, arbitrator,
       administrative agency or instrumentality of the United States or other
       country or jurisdiction is required for the execution and delivery of
       this Agreement by the Company, the performance of its obligations
       hereunder or the consummation of the transactions contemplated hereby,

       as amended, and the regulations thereunder (together, the "EXCHANGE
       ACT"), the Blue Sky Laws applicable to the public offering of the Shares
       by the several Underwriters and the clearance of such offering and the
       underwriting arrangements evidenced hereby with the National Association
       of Securities Dealers, Inc. (the "NASD").  This

<PAGE>   4

       Agreement has been duly executed and delivered by and on behalf of the
       Company and is a valid and binding agreement of the Company enforceable
       against the Company in accordance with its terms, except as
       enforceability of such agreements may be limited by bankruptcy,
       insolvency, reorganization, moratorium or similar laws affecting
       creditors' rights generally.

  (e)  A registration statement on Form S-1 (Reg. No. 333-34971) with respect
       to the Shares, including a preliminary form of prospectus, has been
       carefully prepared by the Company in conformity with the requirements of
       the Act, has been filed with the Securities and Exchange Commission (the
       "COMMISSION") and has been declared effective under the Act.  Such
       registration statement, as finally amended and revised at the time such
       registration statement was or is declared effective by the Commission
       (including the information contained in the form of final prospectus, if
       any, filed with the Commission pursuant to Rule 424(b) and Rule 430A
       under the Act and deemed to be part of the registration statement if the
       registration statement has been declared effective pursuant to Rule
       430A(b)) and as thereafter amended by post-effective amendment, if any,
       is herein referred to as the "REGISTRATION STATEMENT."  The related
       final prospectus in the form first filed with the Commission pursuant to
       Rule 424(b) or, if no such filing is required, as included in the
       Registration Statement, or any supplement thereto, is herein referred to
       as the "PROSPECTUS."  The prospectus subject to completion in the form
       included in the Registration Statement at the time of the initial filing
       of the Registration Statement with the Commission, and each such
       prospectus as amended from time to time until the date of the
       Prospectus, is referred to herein as the "PRELIMINARY PROSPECTUS." The
       Company has prepared and filed such amendments to the Registration
       Statement since its initial filing with the Commission, if any, as may
       have been required to the date hereof, and will file such additional
       amendments thereto as may hereafter be required.  There have been
       delivered to the Representatives three signed copies of the Registration
       Statement and each amendment thereto, if any, together with three copies
       of each exhibit filed therewith, and such number of conformed copies for
       each of the Underwriters of the Registration Statement and each
       amendment thereto, if any (but without exhibits), and of each
       Preliminary Prospectus and of the Prospectus as the Representatives have
       requested.

  (f)  Neither the Commission nor any state securities commission has issued
       any order preventing or suspending the use of any Preliminary
       Prospectus, nor, to the knowledge of the Company, have any proceedings
       for that purpose been initiated or threatened, and each Preliminary
       Prospectus filed with the Commission as part of the Registration
       Statement as originally filed or as part of any amendment or supplement
       thereto complied when so filed with the requirements of the Act and, as
       of its date, did not include any untrue statement of a material fact or
       omit to state a material fact 





                                      -4-

       required to be stated therein or necessary to make the statements
       therein not misleading.  As of the effective date of the Registration
       Statement, and at all times subsequent thereto up to each Closing Date,
       the Registration Statement and the Prospectus contained or will contain
       all statements that are required to be stated therein in accordance with
       the Act and conformed or will conform in all respects to the
       requirements of the Act, and neither the Registration Statement nor the
       Prospectus included or will include any untrue statement of a material
       fact or omitted or will omit to state a material fact required to be
       stated therein or necessary to make the statements therein not
       misleading.  Neither the Company, nor any person that controls, is
       controlled by (including the Subsidiaries) or is under common control
       with the Company, has distributed or will distribute prior to each
       Closing Date any offering material in connection with the offering and
       sale of the Shares other than a Preliminary Prospectus, the Prospectus,
       the Registration Statement or other materials permitted by the Act and
       provided to the Representatives.

  (g)  Arthur Andersen LLP and John S. Eckle, which have expressed their
       respective opinions with respect to the consolidated financial
       statements and schedules filed with the Commission and included as a
       part of each Preliminary Prospectus, the Prospectus or the Registration
       Statement are each independent accountants as required by the Act.

  (h)  The consolidated financial statements and the related notes thereto
       included in each Preliminary Prospectus, the Prospectus and the
       Registration Statement present fairly the financial position, results of
       operations and cash flows of the Company as of their respective dates or
       for the respective periods covered thereby, all in conformity with
       generally accepted accounting principles consistently applied throughout
       the periods involved.  The financial statement schedules, if any,
       included in the Registration Statement present fairly the information
       required to be stated therein on a basis consistent with the
       consolidated financial statements of the Company contained therein.  The
       Company had an outstanding capitalization as set forth in the
       Registration Statement and under "CAPITALIZATION" in the Prospectus as
       of the date indicated therein, and there has been no material change
       thereto since such date except as disclosed in the Prospectus.  The
       financial and statistical information and data relating to the Company
       in each Preliminary Prospectus, the Prospectus and the Registration
       Statement are accurately presented and prepared on a basis consistent
       with the audited consolidated financial statements and books and records
       of the Company.  The consolidated financial statements and schedules and
       the related notes thereto included in each Preliminary Prospectus, the
       Prospectus or the Registration Statement are the only such financial
       statements and schedules required under the Act to be set forth therein.

  (i)  The financial information set forth in the Prospectus under "Summary
       Financial Data", "Selected Consolidated Financial Data" and the "Young
       Innovations, Inc. and Denticator International, Inc. Unaudited Pro Forma
       Financial Information" presents fairly, on the basis stated in each
       Registration Statement and the Prospectus, the information set forth
       therein; the pro forma financial information included in each
       Registration Statement and the Prospectus presents fairly the
       information shown therein and has been prepared in accordance with
       generally accepted accounting principles in the United States and the
       Commission's rules and guidelines with respect to pro forma information;
       and the assumptions used in preparing the pro forma financial statements
       included in each Registration Statement and the Prospectus provide a
       reasonable basis for presenting the significant effects directly
       attributable to the transactions or events described therein, the
       related pro forma adjustments give appropriate effect to those
       assumptions, and the pro forma columns therein reflect the proper
       application of those adjustments to the corresponding historical
       financial statement amounts.

  (j)  Neither the Company nor any Subsidiary is, nor with the giving of notice
       or passage of time or both, would be, in violation or in breach of: (i)
       its respective Articles of Incorporation or By-laws; (ii) any statute,
       ordinance, order, rule or regulation applicable to the Company or such
       Subsidiary; (iii) any order or decree of any court, regulatory body,
       arbitrator, administrative agency or other instrumentality of the United
       States or other country or jurisdiction having jurisdiction over the

       lease, franchise, license, indenture, permit, mortgage, deed of trust,
       evidence of indebtedness or other instrument to which the Company or
       such Subsidiary is a party or by which any property owned or leased by
       the Company or such Subsidiary is bound or affected.  Neither the
       Company nor any Subsidiary has received notice of any violation of any
       applicable statute, ordinance, order, rule or regulation applicable to
       the Company or any Subsidiary.  The Company and each Subsidiary have
       obtained and hold, and are in compliance with, all permits,
       certificates, licenses, approvals, registrations, franchises, consents
       and authorizations of governmental or regulatory authorities required
       under all laws, rules and regulations in connection with their
       businesses (hereinafter "PERMIT" or "PERMITS"), and all of such permits
       are in full force and effect; and the Company and each Subsidiary have
       fulfilled and performed all of their respective obligations with respect
       to each such permit and no event has occurred which would result in, or
       after notice or lapse of time would result in, revocation or termination
       of any such permit or result in any other impairment of the rights of
       the holder of such permit.  Neither the Company nor any Subsidiary is or
       has been (by virtue of any action, omission to act, contract to which it
       is a party or other occurrence) in violation of any applicable foreign,
       federal, state, municipal or local statutes, laws, ordinances, rules,
       regulations or orders (including those relating to





                                      -6-
<PAGE>   7

       environmental protection, occupational safety and health and equal
       employment practices) heretofore or currently in effect.

  (k)  There are no legal or governmental proceedings or investigations pending
       or, to the knowledge of the Company, threatened to which the Company or
       any Subsidiary is or may be a party or to which any property owned or
       leased by the Company or any Subsidiary is or may be subject, including,
       without limitation, any such proceedings that are related to
       environmental or employment discrimination matters, which are required
       to be described in the Registration Statement or the Prospectus which
       are not so described, or which question the validity of this Agreement
       or any action taken or to be taken pursuant hereto.  Except as described
       in the Registration Statement or the Prospectus, neither the Company nor
       any Subsidiary:  (i) is in violation of any statute, ordinance, rule or
       regulation, or any decision, order or decree of any court, regulatory
       body, arbitrator, administrative agency or other instrumentality of the
       United States or other country or jurisdiction having jurisdiction over
       the Company or such Subsidiary relating to the use, disposal or release
       of hazardous or toxic substances or relating to the protection or
       restoration of the environment or human exposure to hazardous or toxic
       substances (collectively, "ENVIRONMENTAL LAWS"); (ii) owns or operates
       any real property contaminated with any substance that is subject to any
       environmental laws; (iii) is liable for any off-site disposal or
       contamination pursuant to any environmental laws; or (iv) is subject to
       any claim relating to any environmental laws, which violation,
       contamination, liability or claim could have a Material Adverse Effect.

  (l)  There is no transaction, relationship, obligation, agreement or other
       document required to be described in the Registration Statement or the
       Prospectus or to be filed or deemed to be filed as an exhibit to the
       Registration Statement by the Act, which has not been described or filed
       as required.  All such contracts or agreements to which the Company or
       any Subsidiary is a party have been duly authorized, executed and
       delivered by the Company or such Subsidiary, constitute valid and
       binding agreements of the Company or such Subsidiary, and are
       enforceable by and against the Company or such Subsidiary, in accordance
       with the respective terms thereof, except as enforceability of such
       contracts and agreements may be limited by bankruptcy, insolvency,
       reorganization, moratorium or similar laws affecting creditors' rights
       generally.

  (m)  The Company or a Subsidiary has good and valid title to all property and
       assets reflected as owned by the Company or such Subsidiary in the
       Company's consolidated financial statements included in the Registration
       Statement (or elsewhere in the Registration Statement or the
       Prospectus), free and clear of all liens, claims, mortgages, security
       interests or other encumbrances of any kind or nature





                                      -7-
<PAGE>   8

       whatsoever except those, if any, reflected in such financial statements
       (or elsewhere in the Registration Statement or the Prospectus).  All
       property (real and personal) held or used by the Company or a Subsidiary
       under leases, licenses, franchises or other agreements is held by the
       Company or such Subsidiary under valid, subsisting, binding and
       enforceable leases, franchises, licenses or other agreements, except as
       enforceability of leases, franchises, licenses or other agreements may
       be limited by bankruptcy, insolvency, reorganization, moratorium or
       similar laws affecting creditors' rights generally.

  (n)  Neither the Company nor any person that controls, is controlled by
       (including the Subsidiaries) or is under common control with the Company
       has taken or will take, directly or indirectly, any action designed to
       cause or result in, or which constituted, or which could cause or result
       in, stabilization or manipulation, under the Exchange Act or otherwise,
       of the price of any security of the Company to facilitate the sale or
       resale of the Common Stock.

  (o)  Except as described in the Registration Statement or the Prospectus,
       since the respective dates as of which information is given in the
       Registration Statement or the Prospectus and prior to each Closing Date:
       (i) neither the Company nor any Subsidiary has or will have incurred any
       liability or obligation, direct or contingent, or entered into any
       transaction, that is material to the Company, except as in the ordinary
       course of business; (ii) the Company has not and will not have paid or
       declared any dividend or other distribution with respect to its capital
       stock and neither the Company nor any Subsidiary is or will be
       delinquent in the payment of principal or interest on any outstanding
       debt obligation; and (iii) there has not been and will not have been any
       change in the capital stock, any material change in the indebtedness of
       the Company or any Subsidiary, or any change or development involving or
       which could be expected to involve, a Material Adverse Effect, whether
       or not arising from transactions in the ordinary course of business.

  (p)  Neither the Company nor any person that controls, is controlled by
       (including the Subsidiaries) or is under common control with the Company
       has, directly or indirectly:  (i) made any unlawful contribution to any
       candidate for political office, or failed to disclose fully any
       contribution in violation of law; or (ii) made any payment to any
       federal, state or foreign governmental officer or official, or other
       person charged with similar public or quasi-public duties, other than
       payments required or permitted by the laws of the United States or any
       jurisdiction thereof or applicable foreign jurisdictions.

  (q)  The Company or a Subsidiary owns or possesses adequate rights to use all
       patents, patent applications, trademarks, service marks, trade names,

       service mark registrations, copyrights and licenses presently used in or
       necessary for the conduct of its business or ownership of its
       properties, and neither the Company nor any Subsidiary has violated or
       infringed upon the rights of others, or received any notice of conflict
       with the asserted rights of others, in respect thereof.

  (r)  The Company or a Subsidiary has in place and effective such policies of
       insurance, with limits of liability in such amounts, as are normal and
       prudent in the ordinary course of the business of the Company and its
       Subsidiaries.

  (s)  No labor dispute with the employees of the Company or any Subsidiary
       exists or, to the knowledge of the Company, is imminent, and neither the
       Company nor any Subsidiary is a party to any collective bargaining
       agreement and, to the knowledge of the Company, no union organizational
       attempts have occurred or are pending.  There has been no change in the
       relationship of the Company or any Subsidiary with any of its principal
       suppliers, manufacturers, contractors or customers resulting in or that
       could result in a Material Adverse Effect.

  (t)  Neither the Company nor any Subsidiary is an "INVESTMENT COMPANY", an
       "AFFILIATED PERSON" of, or "PROMOTER" or "PRINCIPAL UNDERWRITER" for, an
       "INVESTMENT COMPANY", as such terms are defined in the Investment
       Company Act of 1940, as amended.

  (u)  All federal, state and local tax returns required to be filed by or on
       behalf of the Company or any Subsidiary have been filed (or are the
       subject of valid extension) with the appropriate federal, state and
       local authorities, and all such tax returns, as filed, are accurate in
       all material respects; all federal, state and local taxes (including
       estimated tax payments) required to be shown on all such tax returns or
       claimed to be due from or with respect to the business of the Company or
       such Subsidiary have been paid or reflected as a liability on the
       financial statements of the Company or such Subsidiary for appropriate
       periods; except as described in the Registration Statement or the
       Prospectus, all deficiencies asserted as a result of any federal, state
       or local tax audits have been paid or finally settled, and, except as
       described in the Registration Statement or the Prospectus, no issue has
       been raised in any such audit which, by application of the same or
       similar principles, reasonably could be expected to result in a proposed
       deficiency for any other period not so audited; no state of facts exist
       or has existed which would constitute grounds for the assessment of any
       tax liability with respect to the periods which have not been audited by
       appropriate federal, state or local authorities; there are no
       outstanding agreements or waivers extending the statutory period of
       limitation applicable to any federal, state or local tax return of any
       period; and neither the Company nor any Subsidiary has ever been a
       member of an affiliated group of corporations filing consolidated

       tax returns, other than a group of which the Company or Young Dental
       Manufacturing Company is and has been the common parent.

  (v)  Except for the Company's 1997 Stock Option Plan, its nonqualified bonus
       plan and its profit sharing plan, neither the Company nor any Subsidiary
       is a participating employer or plan sponsor with respect to any employee
       pension benefit plan as defined in Section 3(2) of the Employee
       Retirement Income Security Act of 1974, as amended ("ERISA"), or any
       employee welfare benefit plan as defined in Section 3(1) of ERISA,
       including, without limitation, any multiemployer welfare or pension
       plan.  With respect to the Plans, the Company is in substantial
       compliance with all applicable regulations, including ERISA and the
       Code.  With respect to each defined benefit retirement plan, such plan
       does not have benefit liabilities (as defined in Section 4001(a)(16) of
       ERISA) exceeding the assets of the plan.  The Company or the
       administrator of each of the Plans, as the case may be, has timely filed
       the reports required to be filed by ERISA and the Code in connection
       with the maintenance of the Plans, and no facts, including, without
       limitation, any "REPORTABLE EVENT" as defined by ERISA and the
       regulations thereunder, exist in connection with the Plans which, under
       applicable law, would constitute grounds for the termination of any of
       the Plans by the Pension Benefit Guaranty Corporation or for the
       appointment by the appropriate United States District Court of a trustee
       to administer any of the Plans.

  (w)  The Company and each Subsidiary maintain a system of internal accounting
       controls sufficient to provide reasonable assurances that:  (i)
       transactions are executed in accordance with management's general or
       specific authorizations; (ii) transactions are recorded as necessary to
       permit preparation of consolidated financial statements in conformity
       with generally accepted accounting principles and to maintain
       accountability for assets; (iii) access to assets is permitted only in
       accordance with management's general or specific authorizations; and
       (iv) the recorded accountability for assets is compared with existing
       assets at reasonable intervals and appropriate action is taken with
       respect to any differences.

  (x)  None of the Company, any Subsidiary, any officer or director of the
       Company or any Subsidiary, or any person who owns, of record or
       beneficially, any class of securities issued by the Company is:  (i) an
       officer, director or partner of any brokerage firm, broker or dealer
       that is a member of the NASD ("NASD MEMBER"); or (ii) directly or
       indirectly, a "PERSON ASSOCIATED WITH" an NASD member or an "AFFILIATE"
       of an NASD member, as such terms are used in the NASD Rules of Fair
       Practice.  In addition, neither the Company nor any Subsidiary has
       issued or transferred any Common Stock, warrants, options or other
       securities, or any other items of value, to any of the Underwriters or
       any "RELATED PERSON" of any Underwriter, as such term is used in the
       NASD Rules of Fair Practice, except as provided in this Agreement.

  (y)  The Company has prepared and filed with the Commission a registration
       statement for the Common Stock pursuant to Section 12(g) of the Exchange
       Act.  Such registration statement either has been declared effective by
       the Commission under the Exchange Act or will be declared effective by
       the Commission prior to or concurrently with the commencement of the
       public offering of the Shares.  The Common Stock has been approved for
       designation upon notice of issuance as a Nasdaq National Market security

       Subsidiary prior to the date hereof were made in compliance with the Act
       and all other applicable state and federal laws or regulations.

  (aa) The Company has obtained for the benefit of the Underwriters the
       agreement, enforceable by Robert W. Baird & Co. Incorporated ("BAIRD"),
       of each of the officers and directors of the Company, and each of the
       shareholders of the Company, that for a period of 180 days after the
       date of the Prospectus, such persons will not, without the prior written
       consent of Baird, directly or indirectly, offer, sell, transfer, or
       pledge, contract to sell, transfer or pledge, or cause or in any way
       permit to be sold, transferred, pledged, or otherwise disposed of, any:
       (i) shares of Common Stock; (ii) rights to purchase shares of Common
       Stock (including, without limitation, shares of Common Stock that may be
       deemed to be beneficially owned by any such shareholder in accordance
       with the applicable regulations of the Commission and shares of Common
       Stock that may be issued upon the exercise of a stock option, warrant or
       other convertible security); or (iii) securities that are convertible or
       exchangeable into shares of Common Stock.

  (bb) Except as disclosed in the Prospectus, there are no contracts,
       agreements or understandings between the Company and any person that
       would give rise to a valid claim against the Company or any Underwriter
       for a brokerage commission, finder's fee or other like payment.

  A certificate signed by any officer of the Company and delivered to the
Representatives or to counsel for the Underwriters shall be deemed a
representation and warranty by the Company to the Underwriters as to the
matters covered thereby.  A certificate delivered by the Company to its counsel
for purposes of enabling such counsel to render the opinion referred to in
section 8(d) will also be furnished to the Representatives and counsel for the
Underwriters and shall be deemed to be additional representations and
warranties to the Underwriters by the Company as to the matters covered
thereby.

  SECTION 3.  REPRESENTATION OF UNDERWRITERS.  The Representatives will act as
the representatives for the several Underwriters in connection with the public
offering of the Shares, and any action under or in respect of this Agreement
taken by the Representatives will be binding upon all of the Underwriters.

  SECTION 4.  INFORMATION FURNISHED BY THE UNDERWRITERS.  The information set
forth in the last paragraph on the outside front cover page of the Prospectus
concerning the terms of the offering by the Underwriters, the paragraph on the
inside front cover page of the Prospectus relating to stabilization practices,
and the concession and reallowance amounts and the description of stabilizing
practices appearing under the caption "UNDERWRITING" in the Prospectus
constitute all of the information furnished to the Company by and on behalf of
the Underwriters for use in connection with the preparation of the Registration
Statement and the Prospectus, as such information is referred to in this
Agreement.

  SECTION 5.  PURCHASE, SALE AND DELIVERY OF SHARES.

  (a)  On the basis of the representations, warranties and agreements herein
       contained, and subject to the terms and conditions herein set forth, the
       Company agrees to sell to the Underwriters identified in Schedule I
       annexed hereto 2,000,000 Firm Shares, and each of the Underwriters
       agrees, severally and not jointly, to purchase from the Company the
       number of Firm Shares as hereinafter set forth at the price per share of
       $__________.  The obligation of each Underwriter to the Company shall be
       to purchase from the Company that number of full Firm Shares which (as
       nearly as practicable in full shares as determined by the
       Representatives) bears the same proportion to the number of Firm Shares
       to be sold by the Company as the number of shares set forth opposite the
       name of such Underwriter in Schedule I annexed hereto bears to the total
       number of Firm Shares to be purchased by all of the Underwriters under
       this Agreement.

  (b)  On the First Closing Date (as hereinafter defined), the Company will
       deliver to the Representatives, at the offices of Robert W. Baird & Co.
       Incorporated, 227 West Monroe Street, Chicago, Illinois 60606, or
       through the facilities of The Depository Trust Company, for the accounts
       of the several Underwriters, certificates representing the Firm Shares
       to be sold by them against payment of the purchase price therefor in
       funds available on the same day by wire transfer to the account of the
       Company at a bank acceptable to Robert W. Baird & Co.  Incorporated or
       by official Federal Reserve Bank check drawn to the order of the Company
       with respect to the Firm Shares being sold by the Company.  As referred
       to in this Agreement, the "FIRST CLOSING DATE" shall be on the third
       full business day after the date of the Prospectus, at 9:00 a.m.,
       Chicago, Illinois time, or at such other date or time not later than ten
       full business days after the date of the Prospectus as the
       Representatives and





                                      -12-
<PAGE>   13

       the Company may agree.  The certificates for the Firm Shares to be so
       delivered will be in denominations and registered in such names as the
       Representatives request by notice to the Company prior to the First
       Closing Date, and such certificates will be made available for checking
       and packaging at 9:00 a.m., Chicago, Illinois time on the first full
       business day preceding the First Closing Date at a location to be
       designated by the Representatives.

  (c)  In addition, on the basis of the representations, warranties and
       agreements herein contained, and subject to the terms and conditions
       herein set forth, the Company hereby agrees to sell to the Underwriters,
       and the Underwriters, severally and not jointly, shall have the right at
       any time within thirty days after the date of the Prospectus to purchase
       up to 300,000 Optional Shares from the Company at the purchase price per
       share to be paid for the Firm Shares, for use solely in covering any
       over-allotments made by the Underwriters in the sale and distribution of
       the Firm Shares.  Such Optional Shares shall be purchased for the
       account of each Underwriter in the same proportion as the number of Firm
       Shares set forth opposite such Underwriter's name bears to the total
       number of Firm Shares (subject to adjustment by Robert W. Baird & Co.
       Incorporated to eliminate fractions).  The option granted hereunder may
       be exercised upon notice by the Representatives to the Company within
       thirty days after the date of the Prospectus setting forth the aggregate
       number of Optional Shares to be purchased by the Underwriters and sold
       by the Company, the names and denominations in which the certificates
       for such shares are to be registered and the date and place at which
       such certificates will be delivered.  Such date of delivery (the "SECOND
       CLOSING DATE") shall be determined by the Representatives, provided that
       the Second Closing Date, which may be the same as the First Closing
       Date, shall not be earlier than the First Closing Date and, if after the
       First Closing Date, shall not be earlier than three nor later than ten
       full business days after delivery of such notice to exercise.
       Certificates for the Optional Shares will be made available for checking
       and packaging at 9:00 a.m., Chicago, Illinois time, on the first full
       business day preceding the Second Closing Date at a location to be
       designated by the Representatives.  The manner of payment for and
       delivery of (including the denominations of and the names in which
       certificates are to be registered) the Optional Shares shall be the same
       as for the Firm Shares.

  (d)  The Representatives have advised the Company that each Underwriter has
       authorized the Representatives to accept delivery of the Shares and to
       make payment therefor.  It is understood that the Representatives,
       individually and not as representatives of the Underwriters, may (but
       shall not be obligated to) make payment for any Shares to be purchased
       by any Underwriter whose funds shall not have been received by the
       Representatives by the First Closing Date or the Second Closing Date, as
       the case may be, for the account of such Underwriter, but any such
       payment shall not relieve





                                      -13-

       such Underwriter from any obligation under this Agreement.  As referred
       to in this Agreement, "CLOSING DATE" shall mean either the First Closing
       Date or the Second Closing Date.

  SECTION 6.  COVENANTS OF THE COMPANY.  The Company covenants and agrees with
the several Underwriters that:

  (a)  If the effective time of the Registration Statement is not prior to the
       execution and delivery of this Agreement, the Company will use its best
       efforts to cause the Registration Statement to become effective at the
       earliest possible time and, upon notification from the Commission that
       the Registration Statement has become effective, will so advise the
       Representatives and counsel to the Underwriters promptly.  If the
       effective time of the Registration Statement is prior to the execution
       and delivery of this Agreement and any information shall have been
       omitted therefrom in reliance upon Rule 430A, the Company, at the
       earliest possible time, will furnish the Representatives with a copy of
       the Prospectus to be filed by the Company with the Commission to comply
       with Rule 424(b) and Rule 430A under the Act and, if the Representatives
       do not object to the contents thereof, will comply with such Rules. Upon
       compliance with such Rules, the Company will so advise the
       Representatives promptly.  The Company will advise the Representatives
       and counsel to the Underwriters promptly of the issuance by the
       Commission or any state securities commission of any stop order
       suspending the effectiveness of the Registration Statement or of the
       institution of any proceedings for that purpose, or of any notification
       of the suspension of qualification of the Shares for sale in any
       jurisdiction or the initiation or threatening of any proceedings for
       that purpose, and will also advise the Representatives and counsel to
       the Underwriters promptly of any request of the Commission for amendment
       or supplement of the Registration Statement, of any Preliminary
       Prospectus or of the Prospectus, or for additional information, and the
       Company will not file any amendment or supplement to the Registration
       Statement (either before or after it becomes effective), to any
       Preliminary Prospectus or to the Prospectus (including a prospectus
       filed pursuant to Rule 424(b)) if the Representatives have not been
       furnished with a copy prior to such filing (with a reasonable
       opportunity to review such amendment or supplement) or if the
       Representatives object to such filing.

  (b)  If, at any time when a prospectus relating to the Shares is required by
       law to be delivered in connection with sales by an Underwriter or
       dealer, any event occurs as a result of which the Prospectus would
       include an untrue statement of a material fact, or would omit to state
       any material fact required to be stated therein or necessary to make the
       statements therein, in the light of the circumstances under which they
       were made, not misleading, or if it is necessary at any time to
       supplement the Prospectus





                                      -14-
<PAGE>   15

       to comply with the Act, the Company promptly will advise the
       Representatives and counsel to the Underwriters thereof and will
       promptly prepare and file with the Commission, at its expense, an
       amendment to the Registration Statement which will correct such
       statement or omission or an amendment which will effect such compliance;
       and, if any Underwriter is required to deliver a prospectus after the
       effective date of the Registration Statement, the Company, upon request
       of the Representatives, will prepare promptly such prospectus or
       prospectuses as may be necessary to permit compliance with the
       requirements of Section 10(a)(3) of the Act.  The Company consents to
       the use, in accordance with the provisions of the Act and with the Blue
       Sky Laws of the jurisdictions in which the Shares are offered by the
       several Underwriters and by dealers, of each Preliminary Prospectus.

  (c)  Neither the Company nor any Subsidiary will, prior to the Second Closing
       Date, if any, incur any liability or obligation, direct or contingent,
       or enter into any material transaction, other than in the ordinary
       course of business, or enter into any transaction with an "AFFILIATE,"
       as defined in Rule 405 under the Act, which is required to be described
       in the Prospectus pursuant to Item 404 of Regulation S-K under the Act,
       except as described in the Prospectus.

  (d)  Neither the Company nor any Subsidiary will,  prior to the Second
       Closing Date, if any, acquire any of the Common Stock nor will the
       Company declare or pay any dividend or make any other distribution upon
       its Common Stock payable to shareholders of record on a date prior to
       such earlier date, except as described in the Prospectus.

  (e)  The Company will make generally available to its security holders and
       the Representatives an earnings statement as soon as practicable, but in
       no event later than sixty days after the end of its fiscal quarter in
       which the first anniversary of the effective date of the Registration
       Statement occurs, covering a period of twelve consecutive calendar
       months beginning after the effective date of the Registration Statement,
       which will satisfy the provisions of the last paragraph of Section 11(a)
       of the Act and Rule 158 promulgated thereunder.

  (f)  During such period as a prospectus is required by law to be delivered in
       connection with sales by an Underwriter or dealer, the Company will
       furnish to the Representatives, at the expense of the Company, copies of
       the Registration Statement, the Prospectus, any Preliminary Prospectus
       and all amendments and supplements to any such documents in each case as
       soon as available and in such quantities as the Representatives may
       reasonably request.





                                      -15-
<PAGE>   16


  (g)  The Company will apply the net proceeds from the sale of the Shares to
       be sold by it hereunder for the purposes set forth in the Prospectus.

  (h)  The Company will cooperate with the Representatives and counsel to the
       Underwriters in qualifying or registering the Shares for sale under the
       Blue Sky Laws of such jurisdictions as the Representatives designate,
       and will continue such qualifications or registrations in effect so long
       as reasonably requested by the Representatives to effect the
       distribution of the Shares.  The Company shall not be required to
       qualify as a foreign corporation or to file a general consent to service
       of process in any such jurisdiction where it is not presently qualified.
       In each jurisdiction where any of the Shares shall have been qualified
       as provided above, the Company will file such reports and statements as
       may be required to continue such qualification for a period of not less
       than one year from the date of the Prospectus.  The Company shall
       promptly prepare and file with the Commission, from time to time, such
       reports as may be required to be filed by the Act and the Exchange Act,
       and the Company shall comply in all respects with the undertakings given
       by the Company in connection with the qualification or registration of
       the Shares for offering and sale under the Blue Sky Laws.

  (i)  During the period of three years from the date of the Prospectus, the
       Company will furnish to each of the Representatives and to each of the
       other Underwriters who may so request, as soon as available, each
       report, statement or other document of the Company or its Board of
       Directors mailed to its shareholders or filed with the Commission, and
       such other information concerning the Company as the Representatives may
       reasonably request.

  (j)  The Company shall deliver the requisite notice of issuance to Nasdaq and
       shall take all necessary or appropriate action within its power to
       maintain the authorization for trading of the Common Stock as a Nasdaq
       National Market security, or take such action to authorize the Common
       Stock for listing on the New York Stock Exchange or the American Stock
       Exchange, for a period of at least thirty-six months after the date of
       the Prospectus.

  (k)  Except for the issuance and sale by the Company of Common Stock upon
       exercise of presently existing outstanding stock options, the sale of
       the Shares to be sold by the Company pursuant to this Agreement, and the
       grant of employee stock options pursuant to the Company's 1997 Stock
       Option Plan, a copy of which is filed as an exhibit to the Registration
       Statement, and provided that, except as disclosed in the Prospectus,
       none of such options shall be exercisable during the 180-day period
       herein described, the Company shall not, for a period of 180 days after
       the date of the Prospectus, without the prior written consent of Baird,
       directly or indirectly, offer,





                                      -16-
<PAGE>   17

       sell or otherwise dispose of, contract to sell or otherwise dispose of,
       or cause or in any way permit to be sold or otherwise disposed of, any:
       (i) shares of Common Stock; (ii) rights to purchase shares of Common
       Stock; or (iii) securities that are convertible or exchangeable into
       shares of Common Stock.

  (l)  The Company will maintain a transfer agent and, if required by law or
       the rules of The Nasdaq Stock Market or any national securities exchange
       on which the Common Stock is listed, a registrar (which, if permitted by
       applicable laws and rules, may be the same entity as the transfer agent)
       for its Common Stock.  The Company shall, as soon as practicable after
       the date hereof, use its best efforts to obtain listing in Standard and
       Poor's Stock Guide, or such other recognized securities manuals for
       which it may qualify for listing, and the Company shall use its best
       efforts to maintain such listings for at least five years after the
       First Closing Date.

  (m)  If at any time when a prospectus relating to the Shares is required to
       be delivered under the Act, any rumor, publication or event relating to
       or affecting the Company shall occur as a result of which, in the
       opinion of Baird, the market price of the Common Stock has been or is
       likely to be materially affected (regardless of whether such rumor,
       publication or event necessitates a supplement to the Prospectus), the
       Company will, after written notice from Baird advising the Company of
       any of the matters set forth above, promptly consult with Baird
       concerning the advisability and substance of, and, if the Company and
       Baird determine that it is appropriate, disseminate, a press release or
       other public statement responding to or commenting on, such rumor,
       publication or event.

  (n)  If the sale to the Underwriters of the Shares is not consummated for any
       reason other than termination of this Agreement pursuant to section 11
       hereof, without limiting any other rights the Underwriters may have, the
       Company agrees to reimburse the Underwriters upon demand for all
       out-of-pocket expenses (including reasonable fees and expenses of
       counsel for the Underwriters), that shall have been incurred by the
       Underwriters in connection with the proposed purchase and sale of the
       Shares, and the provisions of sections 7 and 10 hereof shall at all
       times be effective and apply.

  (o)  The Company will comply or cause to be complied with the conditions to
       the obligations of the Underwriters in section 8 hereof.

  SECTION 7.  PAYMENT OF EXPENSES.  Whether or not the transactions
contemplated hereunder are consummated or this Agreement becomes effective, or
if this Agreement is terminated for any reason, the Company will pay the costs,
fees and expenses incurred in connection with the public offering of the
Shares.  Such costs, fees and expenses to be paid by the Company include,
without limitation:

       limiting the generality of the foregoing: the registration fees related
       to the filing of the Registration Statement with the Commission; the
       fees and expenses related to the quotation of the Shares on Nasdaq or
       other national securities exchange; the fees and expenses of the
       Company's counsel, accountants, transfer agent and registrar; the costs
       and expenses incurred in connection with the preparation, printing,

       Agreement and the Preliminary and Supplemental Blue Sky Memoranda,
       including, without limitation, shipping expenses via overnight delivery
       and/or courier service to comply with applicable prospectus delivery
       requirements; and the costs and expenses associated with the production
       of materials related to, and travel expenses incurred by the management
       of the Company in connection with, the various meetings to be held
       between the Company's management and prospective investors.

  (b)  All registration fees and expenses, including legal fees and
       disbursements of counsel for the Underwriters incurred in connection
       with qualifying or registering all or any part of the Shares for offer
       and sale under the Blue Sky Laws and the clearing of the public offering

obligations of the several Underwriters under this Agreement shall be subject
to the accuracy of the representations and warranties on the part of the
Company herein set forth as of the date hereof and as of each Closing Date, to
the accuracy of the statements of the Company's officers made pursuant to the
provisions hereof, to the performance by the Company of its obligations
hereunder, and to the following additional conditions, unless waived in writing
by the Representatives:

  (a)  The Registration Statement shall have been declared effective by the
       Commission not later than 2:00 p.m., Washington, D. C. time, on the date
       of this Agreement, or such later time as shall have been consented to by
       the Representatives, which consent shall be deemed to have been given if
       the Registration Statement shall have been declared effective on or
       before the date and time requested in the acceleration request submitted
       on behalf of the Representatives pursuant to Rule 461 under the Act; all
       filings required by Rules 424(b) and 430A under the Act shall have been
       timely





                                      -18-
<PAGE>   19

       made; no stop order suspending the effectiveness of the Registration
       Statement shall have been issued by the Commission or any state
       securities commission nor, to the knowledge of the Company, shall any
       proceedings for that purpose been initiated or threatened; and any
       request of the Commission or any state securities commission for
       inclusion of additional information in the Registration Statement, or
       otherwise, shall have been complied with to the satisfaction of the
       Representatives.

  (b)  Since the dates as of which information is given in the Registration
       Statement:

       (i)   there shall not have occurred any change or development involving,
             or which could be expected to involve, a Material Adverse
             Effect, whether or not arising from transactions in the ordinary
             course of business; and

       (ii)  the Company shall not have sustained any loss or interference 
             from any labor dispute, strike, fire, flood, windstorm,
             accident or other calamity (whether or not insured) or from any
             court or governmental action, order or decree,

the effect of which on the Company, in any such case described in clause (i) or
(ii) above, is in the opinion of the Representatives so material and adverse as
to make it impracticable or inadvisable to proceed with the public offering or
the delivery of the Shares on the terms and in the manner contemplated in the
Registration Statement and the Prospectus.

  (c)  The Representatives shall not have advised the Company that the
       Registration Statement or the Prospectus contains an untrue statement of
       fact that, in the opinion of the Representatives or counsel for the
       Underwriters, is material, or omits to state a fact that, in the opinion
       of the Representatives or such counsel, is material and is required to
       be stated therein or necessary to make the statements therein not
       misleading.

  (d)  The Representatives shall have received an opinion of Armstrong,
       Teasdale, Schlafly & Davis, counsel for the Company addressed to the
       Representatives, as the representatives of the Underwriters, and dated
       the First Closing Date or the Second Closing Date, as the case may be,
       to the effect that:

       (i)   The Company has been duly incorporated and is validly existing as a
             corporation and in good standing under the laws of its
             jurisdiction of incorporation, with full corporate power and
             authority to own, lease and operate its properties and conduct its
             business as presently conducted and as described in the Prospectus
             and the Registration Statement; the Company is duly registered and
             qualified to do business as a foreign corporation under the laws
             of, and is in good standing as such in, each jurisdiction in which
             such





                                      -19-
<PAGE>   20

             registration or qualification is required, except where the 
             failure to so register or qualify would not have a Material 
             Adverse Effect;

       (ii)  The authorized capital stock of the Company consists of 25,000,000
             shares of Common Stock, par value $.01 per share, and all such
             stock conforms as to legal matters to the descriptions thereof in
             the Prospectus and the Registration Statement;

       (iii) The issued and outstanding shares of capital stock of the Company
             immediately prior to the issuance and sale of the Shares to be
             sold by the Company hereunder have been duly authorized and
             validly issued, are fully paid and nonassessable, and there are no
             preemptive, preferential or, except as described in the
             Prospectus, other rights to subscribe for or purchase any shares
             of capital stock of the Company, and to such counsel's knowledge,
             no shares of capital stock of the Company have been issued in
             violation of such rights;

       (iv)  Except for the Subsidiaries, the Company has no subsidiaries, and
             the Company does not own any equity interest in or control,
             directly or indirectly, any other corporation, limited liability
             company, partnership, joint venture, association, trust or other
             business organization except as described in the Prospectus and
             the Registration Statement; each Subsidiary has been duly
             incorporated and is validly existing as a corporation in good
             standing under the laws of its jurisdiction of incorporation, with
             full corporate power and authority to own, lease and operate its
             properties and to conduct its business as presently conducted and
             as described in the Prospectus and the Registration Statement;
             each Subsidiary is duly registered or qualified to do business as
             a foreign corporation under the laws of, and is in good standing
             as such in, each jurisdiction in which such registration or
             qualification is required, except where the failure to so register
             or qualify would not have a Material Adverse Effect; the issued
             and outstanding shares of the capital stock of each Subsidiary
             have been duly authorized and validly issued, are fully paid and
             nonassessable and there are no preemptive, preferential or, to
             such counsel's knowledge, other rights to subscribe for or
             purchase any shares of capital stock of any Subsidiary, and to
             such counsel's knowledge, no shares of capital stock of any
             Subsidiary have been issued in violation of such rights; except as
             otherwise disclosed in the Prospectus, the Company owns directly
             and, to such counsel's knowledge, beneficially all of the issued
             and outstanding capital stock of each Subsidiary, free and clear
             of any and all liens, claims, encumbrances and security interests;





                                      -20-
<PAGE>   21

       (v)   The certificates for the Shares to be delivered hereunder are in 
             due and proper form and conform to the requirements of
             applicable law; and when duly countersigned by the Company's
             transfer agent, and delivered to the Representatives or upon the
             order of the Representatives against payment of the agreed
             consideration therefor in accordance with the provisions of this
             Agreement, the Shares to be sold by the Company represented
             thereby will be duly authorized and validly issued, fully paid and
             nonassessable, and free of any preemptive, preferential or other
             rights to subscribe for or purchase shares of Common Stock;

       (vi)  The Registration Statement has become effective under the Act, 
             and to such counsel's knowledge, no stop order suspending the
             effectiveness of the Registration Statement has been issued and no
             proceedings for that purpose have been initiated or are threatened
             under the Act or any Blue Sky Laws; the Registration Statement and
             the Prospectus and any amendment or supplement thereto (except for
             the financial statements and other statistical or financial data
             included therein as to which such counsel need express no opinion)
             comply as to form in all material respects with the requirements
             of the Act; no facts have come to the attention of such counsel
             which lead it to believe that either the Registration Statement or
             the Prospectus or any amendment or supplement thereto contains any
             untrue statement of a material fact or omitted or will omit to
             state a material fact required to be stated therein or necessary
             to make the statements therein not misleading or that the
             Prospectus, as of the First Closing Date or the Second Closing
             Date, as the case may be, contained any untrue statement of a
             material fact or omitted or will omit to state a material fact
             required to be stated therein or necessary to make the statements
             therein not misleading in light of the circumstances under which
             they were made (except for the financial statements and other
             financial and statistical data included therein as to which such
             counsel need express no opinion); to such counsel's knowledge,
             there are no legal or governmental proceedings pending or
             threatened, including, without limitation, any such proceedings
             that are related to environmental or employment discrimination
             matters, required to be described in the Registration Statement or
             the Prospectus which are not so described or which question the
             validity of this Agreement or any action taken or to be taken
             pursuant thereto, nor, to such counsel's knowledge, is there any
             transaction, relationship, agreement, contract or other document
             of a character required to be described in the Registration
             Statement or the Prospectus or to be filed as an exhibit to the
             Registration Statement by the Act, which is not described or filed
             as required;

             by bankruptcy, insolvency, reorganization, moratorium or similar
             laws affecting creditors' rights generally, and by equitable
             principles limiting the right to specific performance or other
             equitable relief; no consent, approval, authorization or other
             order or decree of any court, regulatory or governmental body,
             arbitrator, administrative agency or other instrumentality of the
             United States or other country or jurisdiction having jurisdiction
             over the Company is required for the execution and delivery of
             this Agreement or the consummation of the transactions
             contemplated by this Agreement (except for compliance with the
             Act, the Exchange Act, applicable Blue Sky Laws and the clearance
             of the underwriting arrangements by the NASD);

     (viii)  The execution, delivery and performance of this Agreement by the
             Company will not:  (A) violate any provisions of the Articles
             of Incorporation or By-laws of the Company or any Subsidiary; (B)
             to such counsel's knowledge, violate any provisions of, or result

             default under, any agreement, lease, franchise, license,
             indenture, permit, mortgage, deed of trust, other evidence of
             indebtedness or other instrument to which the Company or any
             Subsidiary is a party or by which the Company or such Subsidiary,

     (ix)    To such counsel's knowledge, except as described in the Prospectus,
             there are no holders of Common Stock or other securities of the
             Company, or securities that are convertible or exchangeable into
             Common Stock or other securities of the Company, that have rights
             to the registration of such securities under the Act or any Blue
             Sky Laws;





                                      -22-

   (x)      The Common Stock has been designated for inclusion as a National
            Market security on The Nasdaq Stock Market and is registered under
            the Exchange Act;

   (xi)     Neither the Company nor any Subsidiary is, nor with the giving of
            notice or passage of time or both would be, in violation of its
            respective Articles of Incorporation or By-laws or, to such
            counsel's knowledge, in default in any material respect in the
            performance of any agreement, lease, franchise, license, permit,
            mortgage, deed of trust, evidence of indebtedness or other
            instrument, or any other document that is filed as an exhibit to
            the Registration Statement, to which the Company or any Subsidiary
            is subject or bound;

   (xii)    Neither the Company nor any Subsidiary is an "INVESTMENT COMPANY",
            an "AFFILIATED PERSON" of, or "PROMOTER" or "PRINCIPAL UNDERWRITER"
            for, an "INVESTMENT COMPANY", as such terms are defined in the
            Investment Company Act of 1940, as amended, and, upon its receipt
            of any proceeds from the sale of the Shares, the Company will not
            become or be deemed to be an "INVESTMENT COMPANY" thereunder;

   (xiii)   The description in the Registration Statement and the Prospectus of
            statutes, law, regulations, legal and governmental proceedings, and
            contracts and other legal documents described therein fairly and
            correctly present, in all material respects, the information
            required to be included therein by the Act; and

   (xiv)    All offers and sales by the Company and the Subsidiaries of their
            capital stock before the date hereof were at all relevant times
            duly registered under or exempt from the registration requirements
            of the Act, and were duly registered under or the subject of an
            available exemption from the registration requirements of any
            applicable Blue Sky Laws.

In rendering such opinion, counsel for the Company may rely, to the extent
counsel deems such reliance proper, as to matters of fact upon certificates of
officers of the Company and of governmental officials, and copies of all such
certificates shall be furnished to the Representatives and the Underwriters on
or before each Closing Date.

  (e)  The Representatives shall have received an opinion of McDermott, Will &
       Emery, counsel for the Underwriters, dated the First Closing Date or the
       Second Closing Date, as the case may be, with respect to the issuance
       and sale of the Shares by the Company, the Registration Statement and
       other related matters as the Representatives may require, and the
       Company shall have furnished to such counsel such documents





                                      -23-
<PAGE>   24

       and shall have exhibited to them such papers and records as they request
       for the purpose of enabling them to pass upon such matters.

  (f)  The Representatives shall have received on each Closing Date, a
       certificate of George E. Richmond, President and Chief Executive
       Officer, and Michael W. Eggleston, Vice President, Treasurer and Chief
       Financial Officer, of the Company, to the effect that:

       (i)   The representations and warranties of the Company set forth in 
             section 2 hereof are true and correct as of the date of this
             Agreement and as of the date of such certificate, and the Company
             has complied with all the agreements and satisfied all the
             conditions to be performed or satisfied by it at or prior to the
             date of such certificate;

       (ii)  The Commission has not issued an order preventing or suspending the
             use of the Prospectus or any Preliminary Prospectus or any
             amendment or supplement thereto; no stop order suspending the
             effectiveness of the Registration Statement has been issued; and
             to the knowledge of the respective signatories, no proceedings for
             that purpose have been initiated or are pending or contemplated
             under the Act or under the Blue Sky Laws of any jurisdiction;

       (iii) Each of the respective signatories has carefully examined the
             Registration Statement and the Prospectus, and any amendment or
             supplement thereto, and such documents contain all statements
             required to be stated therein, and do not include any untrue
             statement of a material fact or omit to state any material fact
             required to be stated therein or necessary to make the statements
             therein not misleading, and since the date on which the
             Registration Statement was initially filed, no event has occurred
             that was required to be set forth in an amended or supplemented
             prospectus or in an amendment to the Registration Statement that
             has not been so set forth; and

       (iv)  Since the date on which the Registration Statement was initially 
             filed with the Commission, there shall not have occurred any
             change or development involving, or which could be expected to
             involve, a Material Adverse Effect, whether or not arising from
             transactions in the ordinary course of business, except as
             disclosed in the Prospectus and the Registration Statement as
             heretofore amended or (but only if the Representatives expressly
             consent thereto in writing) as disclosed in an amendment or
             supplement thereto filed with the Commission and delivered to the
             Representatives after the execution of this Agreement; since such
             date and except as so disclosed or in the





                                      -24-
<PAGE>   25

             ordinary course of business, the Company has not incurred any
             liability or obligation, direct or indirect, or entered into any
             transaction which is material to the Company; since such date and
             except as so disclosed, there has not been any change in the
             outstanding capital stock of the Company, or any change that is
             material to the Company in the short-term debt or long-term debt
             of the Company; since such date and except as so disclosed, the
             Company has not acquired any of the Common Stock or other capital
             stock of the Company nor has the Company declared or paid any
             dividend, or made any other distribution, upon its outstanding
             Common Stock payable to shareholders of record on a date prior to
             such Closing Date; since such date and except as so disclosed, the
             Company has not incurred any material contingent obligations, and
             no material litigation is pending or threatened against the
             Company; and, since such date and except as so disclosed, the
             Company has not sustained any material loss or interference from
             any strike, fire, flood, windstorm, accident or other calamity
             (whether or not insured) or from any court or governmental action,
             order or decree.

  The delivery of the certificate provided for in this subsection (f) shall be
and constitute a representation and warranty of the Company as to the facts
required in the immediately foregoing clauses (i), (ii), (iii) and (iv) to be
set forth in said certificate.

  (g)  At the time this Agreement is executed and also on each Closing Date,
       there shall be delivered to the Representatives letters addressed to the
       Representatives, as the representatives of the Underwriters, from Arthur
       Andersen LLP, the Company's independent accountants, the first letter to
       be dated the date of this Agreement, the second letter to be dated the
       First Closing Date and the third letter (if applicable) to be dated the
       Second Closing Date, which shall be in form and substance satisfactory
       to the Representatives and shall contain information as of a date within
       five days of the date of such letter.  There shall not have been any
       change or decrease set forth in any of the letters referred to in this
       subsection (g) which makes it impracticable or inadvisable in the
       judgment of the Representatives to proceed with the public offering or
       purchase of the Shares as contemplated hereby.

  (h)  The Shares shall have been qualified or registered for sale under the
       Blue Sky Laws of such jurisdictions as shall have been specified by the
       Representatives, the underwriting terms and arrangements for the
       offering shall have been cleared by the NASD, and the Common Stock shall
       have been designated for inclusion as a Nasdaq National Market security
       on the Nasdaq Stock Market and shall have been registered under the
       Exchange Act.





                                      -25-

  (i)  Receipt of such further certificates and documents as the
       Representatives may reasonably request (including certificates of
       officers of the Company).

  All such opinions, certificates, letters and documents shall be in compliance
with the provisions hereof only if they are reasonably satisfactory to the
Representatives and to McDermott, Will & Emery, counsel for the Underwriters.
The Company shall furnish the Representatives with such manually signed or
conformed copies of such opinions, certificates, letters and documents as the
Representatives may reasonably request.

  If any condition to the Underwriters' obligations hereunder to be satisfied
prior to or at either Closing Date is not so satisfied, this Agreement at the
election of the Representatives will terminate upon notification to the Company
without liability on the part of any Underwriter, including the
Representatives, the Company except for the provisions of section 6(n) hereof,
the expenses to be paid by the Company pursuant to section 7 hereof and except
to the extent provided in section 10 hereof.

  SECTION 9.  MAINTAIN EFFECTIVENESS OF REGISTRATION STATEMENT.  The Company
will use its best efforts to prevent the issuance of any stop order suspending
the effectiveness of the Registration Statement, and, if such stop order is
issued, to obtain as soon as possible the lifting thereof.

  SECTION 10.  INDEMNIFICATION.

  (a)  The Company agrees to indemnify and hold harmless each Underwriter and
       each person, if any, who controls any Underwriter within the meaning of
       the Act or the Exchange Act, from and against any losses, claims,
       damages, expenses, liabilities or actions in respect thereof ("CLAIMS"),
       joint or several, to which such Underwriter or each such controlling
       person may become subject under the Act, the Exchange Act, Blue Sky Laws
       or other federal or state statutory laws or regulations, at common law
       or otherwise (including payments made in settlement of any litigation),
       insofar as such Claims arise out of or are based upon any breach of any
       representation, warranty or covenant made by the Company in this
       Agreement, or any untrue statement or alleged untrue statement of any
       material fact contained in the Registration Statement, any Preliminary
       Prospectus, the Prospectus or any amendment or supplement thereto, or in
       any application filed under any Blue Sky Law or other document executed
       by the Company for that purpose or based upon written information
       furnished by the Company and filed in any state or other jurisdiction to
       qualify any or all of the Shares under the securities laws thereof (any
       such document, application or information being hereinafter called a
       "BLUE SKY APPLICATION") or arise out of or are based upon the omission
       or alleged omission to state therein a material fact required to be
       stated therein or necessary to make the statements therein not
       misleading.  The Company





                                      -26-
<PAGE>   27

       agrees to reimburse each Underwriter and each such controlling person
       for any legal fees or other expenses incurred by such Underwriter or any
       such controlling person in connection with investigating or defending
       any such Claim; provided, however, that the Company will not be liable
       in any such case to the extent that: (i) any such Claim arises out of or
       is based upon an untrue statement or alleged untrue statement or
       omission or alleged omission made in the Registration Statement, any
       Preliminary Prospectus, the Prospectus or supplement thereto or in any
       Blue Sky Application in reliance upon and in conformity with the written
       information furnished to the Company pursuant to section 4 of this
       Agreement; or (ii) such statement or omission was contained or made in
       any Preliminary Prospectus and corrected in the Prospectus and (1) any
       such Claim suffered or incurred by any Underwriter (or any person who
       controls any Underwriter) resulted from an action, claim or suit by any
       person who purchased Shares which are the subject thereof from such
       Underwriter in the offering, and (2) such Underwriter failed to deliver
       or provide a copy of the Prospectus to such person at or prior to the
       confirmation of the sale of such Shares in any case where such delivery
       is required by the Act, unless such failure was due to failure by the
       Company to provide copies of the Prospectus to the Underwriters as
       required by this Agreement.  The indemnification obligations of the
       Company as provided above are in addition to and in no way limit any
       liabilities the Company may otherwise have.

  (b)  Each Underwriter, severally and not jointly, will indemnify and hold
       harmless the Company, each of its directors and each of its officers who
       signs the Registration Statement, and each person, if any, who controls
       the Company within the meaning of the Act or the Exchange Act against
       any Claim to which the Company, or any such director, officer or
       controlling person may become subject under the Act, the Exchange Act,
       Blue Sky Laws or other federal or state statutory laws or regulations,
       at common law or otherwise (including payments made in settlement of any
       litigation, if such settlement is effected with the written consent of
       such Underwriter and Baird), insofar as such Claim arises out of or is
       based upon any untrue or alleged untrue statement of any material fact
       contained in the Registration Statement, any Preliminary Prospectus, the
       Prospectus, or any amendment or supplement thereto, or in any Blue Sky
       Application, or arises out of or is based upon the omission or alleged
       omission to state therein a material fact required to be stated therein
       or necessary to make the statements therein not misleading, in each case
       to the extent, but only to the extent, that such untrue statement or
       alleged untrue statement or omission or alleged omission was made in the
       Registration Statement, any Preliminary Prospectus, the Prospectus, or
       any amendment or supplement thereto, or in any Blue Sky Application, in
       reliance solely upon and in conformity with the written information
       furnished by the Representatives to the Company pursuant to section 4 of
       this Agreement.  Each Underwriter will severally reimburse any legal
       fees or other





                                      -27-
<PAGE>   28

       expenses incurred by the Company, or any such director, officer or
       controlling person in connection with investigating or defending any
       such Claim, and from any and all Claims solely resulting from failure of
       an Underwriter to deliver a Prospectus, if the person asserting such
       Claim purchased Shares from such Underwriter and a copy of the
       Prospectus (as then amended if the Company shall have furnished any
       amendments thereto) was not sent or given by or on behalf of such
       Underwriter to such person, if required by law so to have been
       delivered, at or prior to the written confirmation of the sale of the
       Shares to such person, and if the Prospectus (as so amended) would have
       cured the defect giving rise to such Claim.  The indemnification
       obligations of each Underwriter as provided above are in addition to any
       liabilities any such Underwriter may otherwise have.  Notwithstanding
       the provisions of this section, no Underwriter shall be required to
       indemnify or reimburse the Company, or any officer, director or
       controlling person in an aggregate amount in excess of the total price
       at which the Shares purchased by any such Underwriter hereunder were
       offered to the public, less the amount of any damages such Underwriter
       has otherwise been required to pay by reason of such untrue or alleged
       untrue statement or omission or alleged omission.

  (c)  Promptly after receipt by an indemnified party under this section of
       notice of the commencement of any action in respect of a Claim, such
       indemnified party will, if a Claim in respect thereof is to be made
       against an indemnifying party under this section, notify the
       indemnifying party in writing of the commencement thereof, but the
       omission so to notify the indemnifying party will not relieve an
       indemnifying party from any liability it may have to any indemnified
       party under this section or otherwise.  In case any such action is
       brought against any indemnified party, and such indemnified party
       notifies an indemnifying party of the commencement thereof, the
       indemnifying party will be entitled to participate in and, to the extent
       that he, she or it may wish, jointly with all other indemnifying
       parties, similarly notified, to assume the defense thereof, with counsel
       reasonably satisfactory to such indemnified party; provided, however, if
       the defendants in any such action include both the indemnified party and
       any indemnifying party and the indemnified party shall have reasonably
       concluded that there may be legal defenses available to the indemnified
       party and/or other indemnified parties which are different from or
       additional to those available to any indemnifying party, the indemnified
       party or parties shall have the right to select separate counsel to
       assume such legal defenses and to otherwise participate in the defense
       of such action on behalf of such indemnified party or parties.

  (d)  Upon receipt of notice from the indemnifying party to such indemnified
       party of the indemnifying party's election to assume the defense of such
       action and upon approval by the indemnified party of counsel selected by
       the





                                      -28-
<PAGE>   29

       indemnifying party, the indemnifying party will not be liable to such
       indemnified party under this section for any legal fees or other
       expenses subsequently incurred by such indemnified party in connection
       with the defense thereof, unless:

       (i)   the indemnified party shall have employed separate counsel in
             connection with the assumption of legal defenses in accordance
             with the proviso to the last sentence of subsection (c) of this
             section (it being understood, however, that the indemnifying party
             shall not be liable for the legal fees and expenses of more than
             one separate counsel, approved by Baird, if one or more of the
             Underwriters or their controlling persons are the indemnified
             parties);

       (ii)  the indemnifying party shall not have employed counsel reasonably
             satisfactory to the indemnified party to represent the
             indemnified party within a reasonable time after the indemnified
             party's notice to the indemnifying party of commencement of the
             action; or

       (iii) the indemnifying party has authorized the employment of counsel 
             at the expense of the indemnifying party.

  (e)  If the indemnification provided for in this section is unavailable to an
       indemnified party under subsection (a), (b) or (c) hereof in respect of
       any Claim referred to therein, then each indemnifying party, in lieu of
       indemnifying such indemnified party, shall, subject to the limitations
       hereinafter set forth, contribute to the amount paid or payable by such
       indemnified party as a result of such Claim:

       (i)   in such proportion as is appropriate to reflect the relative 
             benefits received by the Company and the Underwriters from the
             offering of the Shares; or

       (ii)  if the allocation provided by clause (i) above is not permitted by
             applicable law, in such proportion as is appropriate to reflect
             not only the relative benefits referred to in clause (i) above,
             but also the relative fault of the Company and the Underwriters in
             connection with the statements or omissions which resulted in such
             Claim, as well as any other relevant equitable considerations.

  The relative benefits received by each of the Company and the Underwriters
shall be deemed to be in such proportion so that the Underwriters are
responsible for that portion represented by the percentage that the amount of
the underwriting discounts and commissions per share appearing on the cover
page of the Prospectus bears to the public offering price per share appearing
thereon, and the Company (including its officers and directors and controlling
persons) is responsible for the remaining portion.  The relative fault of the
Company and the Underwriters shall be determined by





                                      -29-
<PAGE>   30

reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.  The amount
paid or payable by a party as a result of the Claims referred to above shall be
deemed to include, subject to the limitations set forth in subsections (c) and
(d) of this section, any legal or other fees or expenses reasonably incurred by
such party in connection with investigating or defending any action or claim.

  (f)  The Company and the Underwriters agree that it would not be just and
       equitable if contribution pursuant to this section were determined by
       pro rata or per capita allocation (even if the Underwriters were treated
       as one entity for such purpose) or by any other method or allocation
       which does not take into account the equitable considerations referred
       to in subsection (e) of this section.  Notwithstanding the other
       provisions of this section, no Underwriter shall be required to
       contribute any amount that is greater than the amount by which the total
       price at which the Shares underwritten by it and distributed to the
       public were offered to the public exceeds the amount of any damages
       which such Underwriter has otherwise been required to pay by reason of
       such untrue or alleged untrue statement or omission or alleged omission.
       No person guilty of fraudulent misrepresentation (within the meaning of
       section 11(f) of the Act) shall be entitled to contribution from any
       person who was not guilty of such fraudulent misrepresentation. The
       Underwriters' obligations to contribute pursuant to this section are
       several in proportion to their respective underwriting commitments and
       not joint.

  SECTION 11.  DEFAULT OF UNDERWRITERS.  It shall be a condition to the
obligations of each Underwriter to purchase the Shares in the manner as
described herein, that, except as hereinafter provided in this section, each of
the Underwriters shall purchase and pay for all the Shares agreed to be
purchased by such Underwriter hereunder upon tender to the Representatives of
all such Shares in accordance with the terms hereof.  If any Underwriter or
Underwriters default in their obligations to purchase Shares hereunder on
either the First Closing Date or the Second Closing Date and the aggregate
number of Shares which such defaulting Underwriter or Underwriters agreed but
failed to purchase does not exceed ten percent (10%) of the total number of
Shares which the Underwriters are obligated to purchase on such Closing Date,
the Representatives may make arrangements for the purchase of such Shares by
other persons, including any of the Underwriters, but if no such arrangements
are made by such Closing Date the nondefaulting Underwriters shall be obligated
severally, in proportion to their respective commitments hereunder, to purchase
the Shares which such defaulting Underwriters agreed but failed to purchase on
such Closing Date.  If any Underwriter or Underwriters so default and the
aggregate number of Shares with respect to which such default or defaults occur
is greater than ten percent (10%) of the total number of Shares which the
Underwriters are obligated to purchase on such Closing Date, and arrangements
satisfactory to the Representatives for the purchase of such Shares by other
persons are not made within thirty-six hours





                                      -30-
<PAGE>   31

after such default, this Agreement will terminate without liability on the part
of any nondefaulting Underwriter, the Company except for the expenses to be
paid by the Company pursuant to section 7 hereof and except to the extent
provided in section 10 hereof.

  In the event that Shares to which a default relates are to be purchased by
the nondefaulting Underwriters or by another party or parties, the
Representatives shall have the right to postpone the First Closing Date or the
Second Closing Date, as the case may be, for not more than seven business days
in order that the necessary changes in the Registration Statement, Prospectus
and any other documents, as well as any other arrangements, may be effected.
As used in this Agreement, the term "UNDERWRITER" includes any person
substituted for an Underwriter under this Section.  Nothing herein will relieve
a defaulting Underwriter from liability for its default.

  SECTION 12.  EFFECTIVE DATE.  This Agreement shall become effective upon the
execution and delivery of this Agreement by the parties hereto.  Such execution
and delivery shall include an executed copy of this Agreement sent by
telecopier, facsimile transmission or other means of transmitting written
documents.

  SECTION 13.  TERMINATION.  Without limiting the right to terminate this
Agreement pursuant to any other provision hereof, this Agreement may be
terminated by the Representatives prior to or on the First Closing Date and the
over-allotment option from the Company referred to in section 5 hereof, if
exercised, may be cancelled by the Representatives at any time prior to or on
the Second Closing Date, if in the judgment of the Representatives, payment for
and delivery of the Shares is rendered impracticable or inadvisable because:

  (a)  additional governmental restrictions, not in force and effect on the
       date hereof, shall have been imposed upon trading in securities
       generally or minimum or maximum prices shall have been generally
       established on the New York Stock Exchange or the American Stock
       Exchange, or trading in securities generally shall have been suspended
       or materially limited on either such exchange or on The Nasdaq Stock
       Market or a general banking moratorium shall have been established by
       either federal or state authorities in New York, Missouri or Wisconsin;

  (b)  any event shall have occurred or shall exist which makes untrue or
       incorrect in any material respect any statement or information contained
       in the Registration Statement or which is not reflected in the
       Registration Statement but should be reflected therein to make the
       statements or information contained therein not misleading in any
       material respect; or

  (c)  an outbreak or escalation of hostilities or other national or
       international calamity or any substantial change in political, financial
       or economic conditions shall have occurred or shall have accelerated to
       such extent, in the judgment of the





                                      -31-
<PAGE>   32

       Representatives, as to have a material adverse effect on the financial
       markets of the United States, or to make it impracticable or inadvisable
       to proceed with completion of the sale of and payment for the Shares as
       provided in this Agreement.

  Any termination pursuant to this Section shall be without liability on the
part of any Underwriter to the Company, or on the part of the Company to any
Underwriter, except for expenses to be paid by the Company pursuant to section
7 hereof or reimbursed by the Company pursuant to section 6(n) hereof and
except as to indemnification to the extent provided in section 10 hereof.

  SECTION 14.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY.  The
respective indemnities, agreements, representations, warranties, covenants and
other statements of the Company, of its officers or directors and of the
several Underwriters set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of any Underwriter or the Company or any of its or their partners,
officers, directors or any controlling person, as the case may be, and will
survive delivery of and payment for the Shares sold hereunder.

  SECTION 15.  NOTICES.  All communications hereunder will be in writing and,
if sent to the Representatives, will be mailed, delivered, telecopied (with
receipt confirmed) or telegraphed and confirmed to Robert W. Baird & Co.
Incorporated at 777 East Wisconsin Avenue, Milwaukee, Wisconsin 53202,

Metropolitan Square, Suite 2600, St. Louis, Missouri 63102, Attention:  John L.

  SECTION 16.  SUCCESSORS.  This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors, personal
representatives and assigns, and to the benefit of the officers and directors
and controlling persons referred to in section 10 hereof and no other person
will have any right or obligation hereunder. The term "SUCCESSORS" shall not
include any purchaser of the Shares as such from any of the Underwriters merely
by reason of such purchase.

  SECTION 17.  PARTIAL UNENFORCEABILITY.  If any section, paragraph, clause  or
provision of this Agreement is for any reason determined to be invalid or
unenforceable, such determination shall not affect the validity or
enforceability of any other section, paragraph clause or provision hereof.

  SECTION 18.  APPLICABLE LAW; COUNTERPARTS.  This Agreement shall be governed
by and construed in accordance with the internal laws of the State of Wisconsin
without reference to conflict of law principles thereunder.  This Agreement may
be signed in various counterparts which together





                                      -32-

shall constitute one and the same instrument, and shall be effective when at
least one counterpart hereof shall have been executed by or on behalf of each
party hereto.

  Re:  Registration Statement on Form S-1 for up to 2,300,000 Shares of Common
       Stock

Ladies and Gentlemen:

  We have examined the Registration Statement on Form S-1 (the "Registration
Statement") filed by Young Innovations, Inc., a Missouri corporation (the
"Company"), with the Securities and Exchange Commission on September 3, 1997
(Registration No. 333-34971), as amended to the date hereof, in connection with
the registration under the Securities Act of 1933, as amended, of up to an
aggregate of 2,300,000 shares of the Company's Common Stock, $0.01 par value
per share (the "Common Stock"), of which (i) 2,000,000 are being offered by the
Company, and (ii) up to 300,000 additional shares may be offered by the Company
pursuant to an over-allotment option granted to the underwriters as set forth
in the Registration Statement.

  As your counsel, we have examined the Company's Articles of Incorporation and
Bylaws, each as amended to the date hereof, and the records of corporate
proceedings and other actions taken by the Company in connection with the
authorization, issuance and sale of the Common Stock.  Based upon the foregoing
and in reliance thereon, we are of the opinion that:

  Subject to (i) compliance with applicable state securities laws and (ii)
receipt from the Securities and Exchange Commission of an order declaring the
Registration Statement effective, the 2,000,000 shares of Common Stock to be
sold by the Company and the additional 300,000 shares subject to the
underwriters' over-allotment option (assuming exercise of the underwriters' 
over-allotment option), when issued and sold in the manner described in the 
Registration Statement, will be legally issued, fully paid and nonassessable.

                             1997 STOCK OPTION PLAN


         1.      PURPOSE.

         The purpose of the Plan is to promote the best interests of the
Company and its shareholders by encouraging participants to acquire a
proprietary interest in the Company through the grant of options, thus
identifying their interests with those of shareholders and giving participants
a greater personal interest in the success of the Company.

         2.      ADMINISTRATION.

         (a)     Except as set forth in paragraph 2(c), the Plan shall be
administered by the Compensation Committee, and the selection of participants
in the Plan and decisions concerning the timing, pricing, vesting, other
restrictions, and amount of any grant of options under the Plan shall be made
by the Compensation Committee.  Except as provided in Section 10, and except as
set forth in paragraph 2(c), the Compensation Committee shall interpret the
Plan, prescribe, amend, and rescind rules and regulations relating to the Plan,
and make all other determinations necessary or advisable for its
administration, and the decision of the Compensation Committee on any question
concerning the interpretation of the Plan or any option granted under the Plan
shall be final and binding upon all participants.

         (b)     The Compensation Committee may delegate to one or more
directors, officers or managers of the Company, or a committee of such
directors, officers or managers, the authority, subject to such terms and
limitations as the Compensation Committee shall determine, to grant options to,
or to cancel, modify, waive rights with respect to, alter, discontinue or
terminate options held by participants who are not officers or directors of the
Company for purposes of Section 16 of the Exchange Act.

         (c)     With respect to any options granted to members of the
Compensation Committee, all authority of the Compensation Committee, including
without limitation the grant of options and the administration and
interpretation of the Plan, shall be exercised by the Board.

         3.      PARTICIPANTS.

         Participants in the Plan shall be such Employees as the Compensation
Committee may select from time to time and such Non-Employee Directors as the
Board may select from time to time.  The Compensation Committee may grant
options to an individual upon the condition that the individual become an
Employee, provided that the option shall be deemed to be granted only on the
date the individual becomes an Employee.

<PAGE>   4

         4.      STOCK.

         The stock available for grants of options under the Plan shall be the
Common Stock, and may be either authorized and unissued shares or treasury
shares held by the Company.  The total amount of Common Stock on which options
may be granted under the Plan shall not exceed 350,000 shares, subject to
adjustment in accordance with Section 10.  Shares subject to any unexercised
portion of a terminated, cancelled, expired or forfeited option granted under
the Plan may again be subjected to grants or awards under the Plan.

         5.      GRANT OF OPTIONS.

         (a)     General.  Subject to the limitations set forth in the Plan,
the Compensation Committee from time to time may grant options to such
participants and for such number of shares of Common Stock and upon such other
terms (including, without limitation, the exercise price, the times at which
the option may be exercised, and any applicable vesting requirements) as it
shall designate.  Each option shall be evidenced by a stock option agreement or
other contract in such form and containing such provisions as the Compensation
Committee shall deem appropriate, provided that such terms shall not be
inconsistent with the Plan.  Subject to compliance with paragraph 5(b), any
option may be designated in whole or in part as either an Incentive Stock
Option or a Nonqualified Stock Option.  Any participant may hold more than one
option under the Plan and any other stock option plan of the Company.  The date
on which an option is granted shall be the date of the Compensation Committee's
authorization of the option or such later date as shall be determined by the
Compensation Committee at the time the option is authorized.

         (b)     Incentive Stock Options.  Any option intended to constitute an
Incentive Stock Option shall comply with the following requirements in addition

         Option granted under the Plan shall be not less than the Fair Market
         Value per share of Common Stock on the date the option is granted;
         provided that no Incentive Stock Option shall be granted to any
         participant who owns (within the meaning of Section 424(d) of the
         Code) stock of the Company, or any Parent or Subsidiary, possessing
         more than 10% of the total combined voting power of all classes of
         stock of such Company, Parent or Subsidiary unless, at the date of
         grant of an option to such participant, the exercise price for the
         option is at least 110% of the Fair Market Value of the shares subject
         to option and the option, by its terms, is not exercisable more than
         five years after the date of grant;

                 (ii)     The aggregate Fair Market Value of the underlying
         Common Stock at the time of grant as to which Incentive Stock Options
         under the Plan (or a plan

<PAGE>   5

         of a Subsidiary) may first be exercised by a participant in any
         calendar year shall not exceed $100,000; to the extent that an option
         intended to constitute an Incentive Stock Option shall exceed the
         $100,000 limitation, the portion of the option that exceeds such
         limitation shall be treated as a Nonqualified Stock Option); and

                 (iii)    An Incentive Stock Option shall not be exercisable
         after the 10th anniversary of the date of grant or such lesser period
         as the Compensation Committee may specify from time to time.

         (c)     Nonqualified Stock Options.  A Nonqualified Stock Option shall
be exercisable for a term not to exceed 10 years, or such lesser period as the
Compensation Committee shall determine, and shall be on such other terms and
conditions as the Compensation Committee shall determine.

         6.      PAYMENT FOR SHARES.

         The purchase price for shares of Common Stock to be acquired upon
exercise of an option granted hereunder shall be paid in full, at the time of
exercise, in any of the following ways:

                 (i)      In cash; or

                 (ii)     By certified check, bank draft or money order; or

                 (iii)    If the Compensation Committee so approves at the time
         of exercise, by tendering to the Company shares of Common Stock then
         owned by the participant, duly endorsed for transfer or with duly
         executed stock power attached, which shares shall be valued at their
         Fair Market Value as of the date of such exercise and payment; or

                 (iv)     If the Compensation Committee so approves at the time
         of exercise, by delivery to the Company of a properly executed
         exercise notice, acceptable to the Company, together with irrevocable
         instructions to the participant's broker to deliver to the Company a
         sufficient amount of cash to pay the exercise price and any applicable
         income and employment withholding taxes, in accordance with a written
         agreement between the Company and the brokerage firm ("Cashless
         Exercise") if, at the time of exercise, the Company has entered into
         such an agreement.

         7.      WITHHOLDING TAXES.





                                       3
<PAGE>   6


         (a)     The Company shall have the right to withhold from a
participant's compensation or require a participant to remit sufficient funds
to satisfy applicable withholding for income and employment taxes upon the
exercise of an option.  If the Compensation Committee so approves at the time
of such exercise, (i) a participant may make an election, notice of which shall
be in writing and promptly delivered to the Compensation Committee, to tender
previously-acquired shares of Common Stock or have shares of Common Stock
withheld from the exercise of an option, provided that the shares have an
aggregate Fair Market Value on the date of such exercise sufficient to satisfy
in whole or in part the applicable withholding taxes, or (ii) the Cashless
Exercise procedure described in Section 6 may be utilized to satisfy the
withholding requirement.

         (b)     Except as permitted under Rule 16b-3, a participant subject to
the insider trading restrictions of Section 16(b) of the Exchange Act may use
Common Stock to satisfy the applicable withholding requirements only if notice
of election to so use Common Stock is given or becomes effective within the
"window periods" set forth in Rule 16b-3, or if such election is irrevocable
and made at least six months prior to the date of the exercise.

         8.      NON-ASSIGNABILITY.

         No option (or any rights or obligations related thereto) shall be
transferable by a participant except by will or the laws of descent and
distribution.  During the lifetime of a participant, an option shall be
exercised only by the participant.  No transfer of an option (or any rights or
obligations related thereto) shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and such evidence
as the Company may deem necessary to establish the validity of the transfer and
the acceptance by the transferee of the terms and conditions of such option.

         9.      TERMINATION OF EMPLOYMENT.

         Unless otherwise determined by the Compensation Committee or provided
in the stock option agreement relating to a particular grant of an option:

                 (i)      If, prior to the date that such option shall first
         become exercisable, the participant's Employment shall be terminated
         for any reason, with or without Cause, including by the voluntary act,
         death, Disability, or retirement of the participant, the participant's
         right to exercise the option shall terminate and all rights thereunder
         shall cease;

                 (ii)     If, on or after the date that such option shall first
         become exercisable, a participant's Employment shall be terminated by
         the Company for Cause, the participant's right to exercise the option
         shall terminate and all rights thereunder shall cease;





                                       4
<PAGE>   7


                 (iii)    If, on or after the date that such option shall first
         become exercisable, a participant's Employment shall be terminated due
         to death or Disability, the participant or the executor or
         administrator of the estate of the participant or the person or
         persons to whom the option shall have been transferred by will or by
         the laws of descent and distribution (as the case may be), shall have
         the right, prior to the earlier of (i) the expiration of the option or
         (ii) one year from the date of the participant's death or termination
         due to such Disability, to exercise the option to the extent that it
         was exercisable and unexercised on the date of death or Disability,
         subject to any other limitation on exercise in effect at the date of
         exercise; and

                 (iv)     If, on or after the date that such option shall first
         become exercisable, a participant's Employment shall be terminated for
         any reason other than for Cause or due to the participant's death or
         Disability, the participant shall have the right, prior to the earlier
         of (i) the expiration of the option or (ii) three months after such
         termination of Employment, to exercise the option to the extent that
         it was exercisable and is unexercised on the date of such termination
         of Employment, subject to any other limitation on the exercise of the
         option in effect at the date of exercise; and

The provisions of the preceding clauses (iii) and (iv) shall not apply to the
extent that the shares subject to the option are subject to forfeiture or
repurchase by the Company as a result of the termination of the participant's
employment.

         10.     ADJUSTMENTS.

         (a)     In the event that the Compensation Committee shall determine
that any dividend or other distribution (whether in the form of cash, Common
Stock, other securities, or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of Common Stock or other securities of the
Company, issuance of warrants or other rights to purchase Common Stock or other
securities of the Company, or other similar corporate transaction or event
affects the Common Stock such that an adjustment is determined by the
Compensation Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the Compensation Committee shall, in such manner as it may
deem equitable, adjust any or all of (i) the number and type of shares of
Common Stock which thereafter may be made the subject of options, (ii) the
number and type of shares of Common Stock subject to outstanding options, and
(iii) the exercise price with respect to any option, or, if deemed appropriate,
make provision for a cash payment to the holder of an outstanding option;
provided, however, in each case, that with respect to Incentive Stock Options
no such adjustment shall be authorized to the extent that such authority would
cause the Plan to violate Section 422 of the Code or any successor provision
thereto;





                                       5
<PAGE>   8

and provided further, however, that the number of shares of Common Stock
subject to any option shall always be a whole number.

         (b)     In the event of a Change of Control, unless otherwise
determined by the Compensation Committee, all outstanding options under the
Plan immediately shall become exercisable in full, regardless of any
installment provision applicable to such option; provided, however, that to the
extent that the acceleration of a grant or an award is deemed to constitute a
"golden parachute payment" under Section 280G of the Code and such payment,
when aggregated with other golden parachute payments to the participant results
in an "excess golden parachute payment" under Section 280G of the Code, any
accelerated payment under this Section 10 shall be reduced to the highest
permissible amount that shall not subject the participant to an excess golden
parachute excise tax under Section 4999 of the Code and shall entitle the
Company to retain its full compensation tax deduction for the payment.

         11.     RIGHTS PRIOR TO ISSUANCE OF SHARES.

         No participant shall have any rights as a shareholder with respect to
any shares covered by an option grant until the issuance of a stock certificate
to the participant for such shares.  No adjustment shall be made for dividends
or other rights with respect to such shares for which the record date is prior
to the date such certificate is issued.

         12.     TERMINATION AND AMENDMENT.

         (a)     The Board may terminate the Plan, or the granting of options,
at any time.  No options shall be granted under the Plan after the tenth (10th)
anniversary of the date of the adoption of this Plan by the Board.  Termination
of the Plan shall not affect the rights of the holders of any options
previously granted.

         (b)     The Board may amend or modify the Plan at any time and from
time to time.  No amendment, modification, or termination of the Plan shall in
any manner affect any option granted under the Plan without the consent of the
participant holding same.

         13.     EFFECT ON EMPLOYMENT.

         Neither the adoption of the Plan nor the granting of any option
pursuant to it shall be deemed to create any right in any individual to be
retained as an Employee.

                              EMPLOYMENT AGREEMENT


  THIS EMPLOYMENT AGREEMENT ("Agreement") is made and entered into as of this
8th day of October, 1997, by and between Young Innovations, Inc., a
Missouri corporation ("Employer") and Alfred E. Brennan ("Employee").

  WHEREAS, Employer wishes to employ Employee, and Employee wishes to be
employed by Employer, and the parties wish to set forth the terms of such
employment in writing in this Agreement;

  NOW THEREFORE, in consideration of the premises and the mutual covenants and
agreements herein set forth, Employer hereby employs Employee, and Employee
hereby accepts such employment, upon the following terms:

  1. Term of Employment.

  Unless terminated earlier as set forth in Section 4, the initial term of
Employee's employment shall be 15 months beginning as of October 1, 1997 (the
"Effective Date").  Thereafter, the term of Employee's employment will
automatically be extended for successive one year terms expiring December 31
unless either party notifies the other party at least 60 days before the
expiration of the initial term, or any subsequent term, that it does not wish
to extend this Agreement; but if such notice is given, Employee's employment
will terminate without further notice at the close of business on the last day
of the then current term.

  2. Duties of Employee.

  (a)  Employee shall diligently and faithfully serve Employer as its Senior
Vice President and Chief Operating Officer, reporting to Employer's Chief
Executive Officer.  Employee shall perform such further duties and services
upon special projects related or associated with the business and affairs of
Employer as may from time to time be assigned to him by Employer's Chief
Executive Officer or Board of Directors ("Board"), and shall devote his full
productive time, energies, attention and best efforts to the performance of the
services required by such duties (except as provided in paragraph 2(c)), and
shall diligently support and promote Employer's business, with the objective
that Employer will be operated in an efficient, sound and profitable manner.

  (b)  Employee agrees to serve, if elected or appointed, as a director of
Employer and/or as a director or officer of one or more affiliates of Employer.
Such duties shall be deemed to be part of Employee's duties for Employer, and
Employee shall not be entitled to additional compensation for serving in any
such capacity beyond that provided in this Agreement.

  (c)  It is understood that Employee shall be allowed to pursue certain prior
commitments, not significantly detracting from his obligations under paragraph
2(a), as approved by Employer.

  3. Compensation and Benefits.

  (a)  Salary.  Employee shall receive an initial base salary ("Base Salary")
of $180,000 per year, which shall be payable in accordance with, and shall be
subject to change from time to time in accordance with, Employer's executive
payroll and compensation policies and procedures.  However, the Base Salary
shall not be less than $180,000 per year.

  (b)  Stock Option.  Effective on the Effective Date, Employer shall issue to
Employee an option to acquire up to 60,000 shares of Employer's common stock
(the "Option").  The Option shall be issued pursuant to Employer's proposed
1997 Stock Option Plan (the "Option Plan"), a draft copy of which Employee
hereby acknowledges having received.  If for any reason the Option Plan is not
adopted or is not approved by Employer's shareholders, the Option will be
granted on terms comparable to those of the Option Plan.  The Option shall
contain the following specific provisions:

       Date and Duration of Option.  The Option shall be issued as of and 
  subject to the occurrence of the pricing date (the "Pricing Date") of
  Employer's currently proposed initial public offering (the "IPO"), and shall
  expire, to the extent not exercised, ten years after the Pricing Date,
  subject to possible earlier termination as set forth in the Option Plan.

       Exercisability of Option.  The Option shall be immediately exercisable 
  as to 15,000 shares, and shall become exercisable as to an additional
  15,000 shares on January 1 of each of the years 1999, 2000 and 2001, so that
  it shall be exercisable as to all Option Shares on January 1, 2001.  However,
  if there is a Change in Control prior to the expiration date of the Option
  the Option shall become immediately exercisable, to the extent it was not
  previously exercisable, as to all Option Shares.

       Exercise Price.  The exercise price of the Option shall be equal to the
  offering price to the public of the shares offered in the IPO.

       Type of Option.  The Option shall be an incentive stock option ("ISO") if
  and to the extent permitted under the Option Plan and related Federal tax
  laws and regulations.  To the extent the aggregate fair market value of the
  underlying Option Shares, measured at the time of grant, as to which the
  Option first becomes exercisable in any calendar year exceeds $100,000, the
  portion of the option that exceeds such limitation will be a nonqualified
  stock option.

  (c)  Fringe Benefits.  Employee shall be entitled to participate in such
retirement and other employee benefit plans as Employer may adopt for its
employees or its senior executives generally, and shall receive such other
fringe benefits and executive perquisites which are afforded by Employer from
time to time to its senior executives or which are otherwise agreed upon
between Employee and the Board.

  (d)  Business Expenses.  Employee shall be entitled to reimbursement of his
expenses reasonably incurred in the promotion and conduct of Employer's
business, subject to the oversight of Employer's Chief Executive Officer and to
any limitations or policies applicable to Employer's executives generally, and
subject to compliance with such substantiation and record-keeping requirements
as may be required from time to time to support the deductibility of such
expenses for Federal income tax purposes.

  4. Termination of Employment.

  (a)  Termination in Certain Events by Either Party.  Employee's employment
may be terminated by either party if:

       (i)   the closing of the sale of the shares offered in the IPO has not 
  occurred by November 30, 1997, or

       (ii)  the Company has not executed a definitive agreement for, or
  consummated, the acquisition of an entity with at least $8 million of
  revenues by March 31, 1998,

and the terminating party gives written notice of termination to the other
party within 30 days after the occurrence of such event.

  (b)  Termination by Employer for Cause.  Except as provided in paragraph
4(a), during the term of this Agreement Employee's employment may be terminated
by Employer without breach of this Agreement only for "Cause," which with
respect to a termination by Employer means only:

       (i)   conviction (including a plea of nolo contendere) of a felony or any
  other crime involving moral turpitude, unethical business conduct, or
  dishonesty involving the Company or persons having business dealings with the
  Company, or

       (ii)  any dishonest or unethical conduct which in the judgment of a 
  majority of the Board (with Employee not voting) may reasonably be
  expected to materially adversely affect Employer's business, or





                                      -3-
<PAGE>   4


       (iii)  any material breach of Employee's covenants set forth in this
  Agreement which is not cured within ten (10) days after Employee is notified
  of such breach by Employer, or

       (iv)  Employee's inability or refusal, for any reason, to fully perform
  his duties under this Agreement for a period of ninety (90) consecutive
  calendar days or for a total of thirty (30) business days in any six (6)
  month period.

  (c)  Termination by Employee for Cause.  Except as provided in paragraph
4(a), during the term of this Agreement Employee may voluntarily terminate his
employment without breach of this Agreement only for "Cause," which with
respect to a termination by Employee means only:

       (i)   the cessation of Employer's normal business operations other than 
  in connection with the orderly liquidation of Employer's business, or

       (ii)  Employer's failure to pay Employee his compensation under this
  Agreement generally in a timely manner, or

       (iii)  any other material violation of Employer's covenants set forth in
  this Agreement which is not cured within ten (10) days after Employer is
  notified of such violation by Employee.

  (d)  Effect of Termination by Employer for Cause or by Employee Without
Cause.  If Employee's employment is terminated by Employer for Cause as set
forth in paragraph 4(b), or if Employee terminates his employment for any
reason other than for Cause as set forth in paragraph 4(c), then all further
obligations of Employer under this Agreement shall automatically terminate,
except for Base Salary and fringe benefits accrued through the effective date
of termination and such other benefits as may be provided by law.

  (e)  Effect of Termination by Death of Employee.  In the event of Employee's
death, all further obligations of Employer under this Agreement shall
automatically terminate, except that Employer shall pay to such person as may
have been designated by Employee in a writing filed with Employer as the
beneficiary under this Agreement or, if no such designation has been made, to
any person designated by Employee in a writing filed with Employer as
Employee's beneficiary under Employer's retirement plans or, if no such
designation has been made, then to the personal representative of Employee's
estate, the Base Salary and fringe benefits accrued through the effective date
of termination and such other benefits as may be provided by law.

  (f)  Limitation on Liability of Employer for Other Terminations.  If
Employee's employment is terminated by Employer for any reason other than Cause
as set forth in paragraph 4(b), or if Employee terminates his employment for
Cause as set forth in paragraph 4(c), then Employer's liability to Employee, in
damages or otherwise, on account of such termination shall be limited to (i)
Employee's Base Salary for the remainder of the then current employment term
plus, if the termination is within 30 days of the end of the current term and
Employer has not given notice of non-renewal pursuant to Section 1, Employee's
Base Salary for the following one-year term, plus (ii) the value of any fringe
benefits which would have accrued through the end of the current term, or if
the termination is within 30 days of the end of





                                      -4-
<PAGE>   5

the current term and Employer has not given notice of non-renewal pursuant to
Section 1, the following term, plus (iii) such other benefits as may be
provided by law.

  (g)  Other Rights Not Affected.  The enumeration of certain rights or
liabilities of the parties effective upon termination of Employee's employment
shall not affect any rights or remedies of a party at law or in equity for any
breach of this Agreement by the other party.  In addition, upon any termination
of Employee's employment, including by reason of Employee's death, Employer may
accelerate, offset and withhold from any amounts due to Employee or his
beneficiary or personal representative any indebtedness of Employee to Employer
existing at the effective date of termination.

  5. Covenants Relating to Confidential Information.

  (a)  Duty Not to Disclose Confidential Information. Employee covenants to use
his best efforts and exercise utmost diligence to protect and guard Employer's
trade secrets, know-how, methods, resources, financial models, business
procedures and processes, customer lists, records, computer information and all
other confidential information relating to Employer's business (hereinafter
individually and collectively referred to as "Confidential Information").  Both
during Employee's employment by Employer and thereafter, Employee shall not,
directly or indirectly, use for Employee's benefit or for the benefit of any
other person or entity, or disclose to any other person or entity, any
Confidential Information, whether or not acquired, learned, obtained or
developed by Employee alone or in conjunction with others, except as such
disclosure or use may be required in connection with Employee's employment by
Employer or may be expressly consented to in writing by Employer.  Employee's
obligations under this paragraph shall terminate upon termination of Employee's
employment as to any Confidential Information which:

       (i)   was known to Employee prior to the commencement of his employment 
  (and not merely prior to the Effective Date), or

       (ii)  is now generally known to the public, or hereafter becomes 
  generally known to the public otherwise than through a breach of this
  Agreement, but in such latter event only as of the date such Confidential
  Information becomes generally known to the public and without terminating any
  liability of Employee to Employer for unauthorized disclosure prior to such
  date, or

       (iii)  is made available to Employee by a third party not under any 
  duty of confidentiality with respect to such Confidential Information.

  (b)  Delivery of Tangible Information.  Employee shall deliver promptly to
Employer at the termination of his employment or at any other time Employer may
reasonably request, without retaining any copies, notes or excerpts thereof,
all work sheets, memoranda, diaries, notes, records, computer printouts,
computer storage media, address books, files and any other documents made or
compiled or otherwise obtained by, or delivered or made available to, Employee
as a result of Employee's employment and containing, or relating directly or
indirectly to, any Confidential Information.

<PAGE>   6


  (c)  Each of the foregoing obligations of Employee in this paragraph shall
also apply with respect to Confidential Information of customers and others
with whom the Company has a business relationship, learned or acquired by
Employee during the course of his or her employment by the Company.

  (d)  Upon termination of Employee's employment, Employee agrees not to notify
any customer of the Company of Employee's termination until the Company has
discussed with said customer plans for transferring the handling of such
customer's orders or other business to other personnel of the Company, and
Employee further agrees to cooperate with the Company to the end that all
customers of the Company with whom Employee has had a business relationship may
be retained by the Company.

  6. Non-Inducement Covenant.

  Employee hereby expressly covenants and agrees that during the period of
Employee's employment with the Company and for a period of two (2) years after
the termination of such employment (irrespective of whether such termination
shall be voluntary or involuntary on the part of Employee), Employee shall not
without the express written consent of the Company directly or indirectly, in
Employee's own behalf or on behalf of any other person or entity, hire or
solicit for hire any employee of the Company, or induce any person employed by
the Company to leave the employ of the Company for any reason.

  7. Intellectual Property.

  Employee hereby agrees that all right, title, and interest in and to any
inventions (whether or not they are patentable) and copyrightable works of
authorship that Employee has made, whether solely or jointly, during his
employment by Employer or that Employee makes, whether solely or jointly, while
an employee of Employer, and which are either within the scope of Employee's
employment or are made at Employer's specific request, including but not
limited to the financial models and similar intellectual property currently
being used by Employer and any modifications or enhancements thereof, shall
belong exclusively to Employer; and Employee agrees to assign and hereby does
assign all right, title and interest in and to such inventions and works of
authorship to Employer and agrees to execute such further assignments and other
documents as Employer may reasonably require in order to secure and enforce
Employer's rights therein.

  8. Disclosure.

  Each party hereby authorizes the other to disclose the existence of this
Agreement and the restrictive covenants set forth herein to third parties,
including but not necessarily limited to prospective employers of Employee,
without incurring any liability for so acting.

  9. Review and Consultation.

  Employee acknowledges that he has had a opportunity to review this Agreement
and consult with his legal and financial advisers prior to signing this
Agreement.

  10.  Miscellaneous.

  (a)  Notices.  All notices and communications hereunder shall be in writing,
and shall be deemed to be duly given if either actually received by the party
entitled thereto (in the case of Employer, by its Chief Executive Officer) or
two business days after its deposit in the United States mail, registered or
certified mail, return receipt requested, postage prepaid, addressed as
follows:

                    If to Employee:  Alfred E. Brennan           
                                     -------------------         
                                     -------------------         
                                                                            
                    If to Employer:  Young Innovations, Inc.     
                                     13705 Shoreline Court                  
                                     Earth City, MO 63045                   
                                     Attention:  Chief Executive Officer    

Either party may change its designated address for receipt of notices by giving
written notice thereof to the other party.

  (b)  Entire Agreement; Modification and Waiver.  This Agreement constitutes
the full and complete understanding and agreement of the parties with respect
to Employee's employment by Employer, supersedes all prior written or oral
understandings and agreements with respect thereto, and cannot be amended or
terminated orally.  Any amendment shall be binding against Employer only if
approved by a majority of the Board, with Employee not voting.  Unless
otherwise expressly stated in writing, any waiver of any provision of this
Agreement shall not constitute a waiver of any other provision; nor shall a
waiver of any breach of any covenant of this Agreement constitute a waiver of
any succeeding or continuing breach of the same, or any other, covenant.

  (c)  Remedies of Employer Upon Breach of Agreement.  Employee acknowledges
that irreparable harm would be sustained by Employer if Employee breaches the
covenants set forth in this Agreement, and Employee therefore agrees that
without prejudice to any other rights or remedies which Employer may have under
this Agreement or at law or in equity, Employer shall be entitled to apply to
any court of competent jurisdiction for, and to obtain, injunctive relief
against Employee in order to prevent any breach or threatened breach of such
covenant.  Employee hereby acknowledges that Employer's business is national in
scope and therefore expressly agrees that the limitation of the covenants in
this Agreement to a specific geographical area within the United States would
not adequately protect the Company.

  (d)  Severability of Certain Provisions.  It is the intention of the parties
that the confidentiality and non-competition covenants in this Agreement are
intended to restrict Employee's activities only to the extent necessary for the
protection of the legitimate business interests of Employer, and the parties
specifically covenant that if any of the foregoing provisions are held to be
too broad for such purpose the Court having power to make such adjudication is
authorized to modify or interpret such provisions to the end that such
restrictions, as modified,





                                      -7-
<PAGE>   8

shall be reasonable and valid; and that if any of the foregoing provisions
shall be held to be invalid or unenforceable, the same shall be deemed to be
severable and shall not defeat the remaining provisions.

  (e)  Binding Effect of Agreement.  This Agreement shall be binding upon
Employee and, except as regards personal services, upon Employee's heirs,
personal representatives, executors and administrators, and shall inure to the
benefit of Employer and its successors and assigns.  Employee expressly
consents to the assignment of this Agreement to any successor to all or
substantially all of Employer's business, and agrees to perform the duties and
services required of him herein for any such successor assignee.

  (f)  Governing Law; Situs of Suit.  This Agreement shall be governed by, and
interpreted in accordance with, the internal laws of the State of Missouri.
Employee agrees that he may be sued, and hereby waives any right to contest
jurisdiction or venue, in the Circuit Court of St.  Louis County, Missouri or
the United States District Court for the Eastern District of Missouri, which
courts, except in the case of proceedings under paragraph 12(c), shall be the
exclusive forums in any proceedings by either party concerning this Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day and
year first above written.


                          Employee:  /s/ Alfred E. Brennan
