                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  JUNE 30, 1998

(1) INTERIM FINANCIAL STATEMENTS

The accompanying unaudited financial statements include all adjustments
(consisting only of normal recurring accruals) which are, in the opinion of
management, necessary for fair presentation of the results of operations for the
periods presented. Interim results are not necessarily indicative of the results
to be expected for a full year.

Certain information and footnote disclosures normally included in financial
statements, prepared in accordance with generally accepted accounting
principles, have been condensed or omitted as allowed by Form 10-Q. The
accompanying unaudited consolidated financial statements should be read in
conjunction with the Company's consolidated financial statements for the year
ended December 31, 1997 as filed with the Securities and Exchange Commission on
Form 10-K.

(2) EARNINGS PER SHARE

Basic earnings per share was computed by dividing net income by the
weighted-average common shares outstanding. Diluted earnings per share was
computed by giving the effect to all dilutive potential common shares
outstanding. These shares include shares issuable upon the exercise of options
and warrants as determined by the application of the treasury stock method. The
calculation of basic earnings per share and diluted earnings per share is as
follows:

Options to purchase 1,500 shares of common stock at $ 25.00 per share were
outstanding during the second quarter of 1998 but were not included in the
computation of diluted earnings per share because the options' exercise price
was greater than the average market price of the common shares. The options,
which expire April 2008, were still outstanding on June 30, 1998.


(3) COMPREHENSIVE INCOME

Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income," establishes standards for reporting and displaying comprehensive income
and its components. The Company adopted the statement in its quarter ending
March 31, 1998. The Company does not have any other items of comprehensive
income. As such, comprehensive income is equal to net income as presented in the
consolidated statements of income.

ITEM 2.

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

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


LIQUIDITY AND CAPITAL RESOURCES

         Working capital increased from $9,611,000 at December 31, 1997 to
$11,240,000 at June 30, 1998. Cash and equivalents increased $616,000 from
$4,912,000 at December 31, 1997. Operating activities provided $2,508,000 in
cash flow for the six months ended June 30,1998. Cash outflows related to dental
laboratory acquisitions totaled $1,774,000 for the same period.

         The Company maintains a financing agreement (the "Agreement") with
State Street Bank and Trust Company (the "Bank"). The Agreement, as amended and
extended on June 27, 1997, includes revolving lines of credit of $4,000,000 and
$8,000,000. The interest rate on both revolving lines of credit is the prime
rate minus 0.5% or the LIBOR rate plus 1.5%, at the Company's option. Both
revolving lines of credit mature on June 1, 2001. A commitment fee of one eighth
of 1% is payable on the unused amount of both revolving lines of credit. At June
30, 1998 the full principal amount was available to the Company under both
revolving lines of credit.

         Management believes that cash flow from operations and the Company's
existing financing will be sufficient to meet contemplated operating and capital
requirements, including costs associated with anticipated acquisitions, if any,
in the foreseeable future.

         This Form 10-Q contains forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. The Company's actual results could
differ materially from those set forth in the forward-looking statements.
Certain factors that could affect capital expenditures, the Company's
requirements for capital, the costs associated with anticipated acquisitions and
the Company's results of operations include general economic conditions, the
availability of laboratories for purchase by the Company, the ability of the
Company to acquire and successfully operate additional dental laboratories,
governmental regulation of health care, trends in the dental industry towards
managed care, other factors affecting patient visits to the Company's clients,
increases in labor and materials costs and other risks indicated in filings with
the Securities and Exchange Commission.

   SIX MONTHS ENDED JUNE 30, 1998 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1997

Net Sales

         Net sales increased $2,603,000 or 8.9% in the six months ended June 30,
1998 over the corresponding period of the prior year. Approximately $1,851,000
of this increase is attributable to business at dental laboratories owned less
than one year, with the remaining increase representing unit growth at dental
laboratories owned during both the six months ended June 30, 1998 and the
comparable six months ended June 30, 1997.

Cost of Goods Sold

         Cost of goods sold, which consists principally of labor and related
benefits, cost of materials, and laboratory overhead, increased by $1,593,000.
As a percentage of sales, cost of goods sold increased from 56.0% to 56.5%,
representing a gross margin decrease of .5%. Increases in materials costs and
laboratory overhead expenses were partially offset by improvements in labor
productivity. The rising cost of palladium, a component of dental alloys used in
the manufacture of many of the Company's goods, was a factor in the increased
materials costs. The Company has attempted to address the cost of this material
in each marketplace and has made efforts to recover costs through price
increases, temporary surcharges and the use of substitute metals in place of
palladium-based materials.

Total Operating Expenses

         Total operating expenses, which consist of (i) selling expenses, the
cost of the Company's pick-up and delivery services and administrative expenses
at the dental laboratory level, and (ii) costs of operation by the Company's
corporate headquarters and field support services, increased by $577,000 or 6.3%
during the six months ended June 30, 1998 over the corresponding period in 1997.

         Operating expenses decreased as a percentage of net sales from 31.2%
to 30.4% during the six months ended June 30, 1998 compared with the
corresponding period in 1997. Declines in laboratory incentive compensation,
field selling expenses and corporate administrative expenses were partially
offset by increased amortization expense.

Operating Income

         Operating income increased by $433,000 or 11.6% for the six months
ended June 30, 1998 over the corresponding period in 1997. The increase was the
result of higher sales volume and reductions in operating expenses as a
percentage of net sales, partially offset by an increase in cost of goods sold.

Other Income

         Other income decreased $49,000 in the six months ended June 30, 1998
compared to the same period in 1997. This decrease was primarily due to
increased usage of credit cards by customers and a reduction in accounts
receivable service charge income on past due balances.

Interest Income

         Interest income increased by $21,000 or 60.4% in the six months ended
June 30, 1998 over the corresponding period in 1997. The increase was primarily
due to increased investment principal.

Provision for Income Taxes

         The Company's provision for income taxes for the six months ended June
30, 1998 increased to $1,685,000 from $1,524,000 in the corresponding period in
1997. The effective tax rate remained constant at 39.8%.

Net Income

         As a result of the factors discussed above, net income for the six
months ended June 30, 1998 increased by $244,000 or 10.6% over the corresponding
period in 1997. Net income per share, on a diluted basis, increased from $0.67
per share to $0.73 per share.

Year 2000 Compliance

         The Company's computer software systems are licensed from outside
vendors. The Company's principal outside vendors have released upgrades of their
software which the vendors represent are "Year 2000 compliant." The Company
expects to complete installation of these software upgrades by the end of the
second quarter in 1999, at which time the Company believes that its computer
systems will be Year 2000 compliant. The Company believes that the costs of such
compliance will not be material to the Company's results of operations or
financial condition. The Company also has relationships with customers, vendors
and other third parties that have computer software systems that may not be Year
2000 compliant. As these systems are outside of the Company's control, there can
be no assurance that potential systems interruptions would not have a material
adverse effect on the Company.
