NOTES TO FINANCIAL STATEMENTS

Note 1 - Basis of Presentation of Financial Statements

The accompanying financial statements should be read in conjunction with the
Notes to Financial Statements and Management's Discussion and Analysis of
Results of Operations and Financial Condition included in the Company's 1998
Annual Report filed on Form 10-K and in this Form 10-Q Report.

In the opinion of management, all adjustments necessary for a fair presentation
of the results for the interim periods have been made.  The results of
operations for the third quarter and first three quarters ended 1999 are not
necessarily indicative of the results to be expected for the full year.  The
fiscal quarters ended October 2, 1999 and October 3, 1998.

Certain prior year amounts have been reclassified to conform with the current
year presentation.

Note 2 - Contingencies

Beginning in 1991, the Company entered into various supply contracts with the
U.S. Department of Veterans Affairs and the Defense Department.  In April 1997,
the Company completed a review of its compliance with various pricing provisions
of these contracts and, with the assistance of special legal counsel, concluded
that adjustments may be due to the federal agencies for potential unasserted
claims against the Company relating to pricing deficiencies under product supply
contracts subject to General Services Administration and Department of Defense
regulations.  In the fourth quarter of 1996 the Company established a $3.8
million reserve for estimated pricing deficiency liabilities and associated
legal costs.  As of the end of 1998 and third quarter end of 1999, the reserve
balance was $3.2 million.  The final amount of the pricing deficiency adjustment
is subject to the outcome of contract settlement discussions between the Company
and  the governmental agencies or to an adjudicated disposition.  In
management's opinion, the ultimate resolution of this matter will not have a
material adverse effect on the Company's financial position.  Although
management believes that the reserve is sufficient, it is possible the final
resolution could exceed such reserve and could have a material impact on the
statement of operations and cash flow in such period.

In 1997, the Company established a $4.5 million restructuring reserve relating
to its exit from the wholesale drug distribution business.  At the end of 1998,
and the third quarter end of 1999, approximately $1.0 million and $0.8 million,
respectively, remained.

</TABLE>


     RESULTS OF OPERATIONS
     ---------------------

     Third Quarter
     1999 Compared with 1998
     -----------------------

     Net sales for the third quarter of 1999 declined 4% to $31.1 million from a
     record $32.5 million of the comparable quarter in the prior year. Net
     income for the third quarter decreased to $0.8 million compared with $1.1
     million in the third quarter of 1998. Earnings per share decreased to $.27
     in the third quarter from $.36 a year ago. The third quarter 1999
     comparison to the comparable quarter in 1998 reflects the contrast to
     record earnings in the prior year, and the result of current operational
     disruptions associated with the impact of the acclimation to the
     Enterprise Resource Planning (ERP) system. The third quarter of 1999 also
     reflects a net income tax benefit of approximately $0.3 million largely
     resulting from management's conclusion of prior year's tax return audits
     performed by the Internal Revenue Service. In management's opinion,
     adequate provisions for income taxes have been made for all years.

                                       8
<PAGE>

For the third quarter, gross profit dollars decreased 7% to $9.4 million.  The
gross profit margin in the 1999 quarter decreased to 30.4% of sales from 31.4%
in the same quarter a year ago.  This decrease is due to higher than anticipated
sales returns and allowances attributable to the initial implementation of the
ERP system partially offset by a favorable product mix of sales.

Selling, general and administrative expenses during the third quarter of 1999
increased 1%.  The increase was primarily attributable to expenses related to
the implementation of the Company's ERP system and outside information
technology consulting.

First Three Quarters
1999 Compared with 1998
-----------------------

Net sales for the first nine months of 1999 declined 4% to $89.5 million from
$93.5 million in the prior year. Net income for the nine months of 1999
decreased to $1.7 million compared with $2.2 million in the same period of 1998.
Earnings per share decreased to $.58 from $.74 a year ago. The comparisons to
record third quarter 1998 earnings and the results for the first nine months of
1999 reflect the operating disruption associated with the impact of the
implementation of the ERP system during the current year, as well as the
continuing efforts to acclimate all business practices associated with the ERP
system. The first three quarters of 1999 also reflects a net income tax benefit
of approximately $0.3 million largely resulting from management's conclusion of
prior year's tax return audits performed by the Internal Revenue Service. In
management's opinion, adequate provisions for income taxes have been made for
all years.

For the first nine months of 1999, gross profit dollars decreased 3% to $28.2
million.  The gross profit margin rate increased in the first nine months of
1999 to 31.5% from 30.9% in the same period in 1998.  The improvement in margin
rate is primarily attributable to a favorable product mix in sales.

Selling, general and administrative expenses during the first nine months of
1999 increased 2% compared to the first nine months of 1998.  The increase is
primarily due to expenses related to implementation of the Company's ERP
information technology system.

FINANCIAL CONDITION
-------------------

During the first nine months of 1999, the Company utilized existing credit lines
of $2.7 million and decreased cash by $3.5 million to fund $1.8 million of net
cash used for operations and $4.4 million of capital expenditures.  Accounts
receivable increased $4.9 million due to higher sales at the end of the third
quarter of 1999 than at year end of 1998.

                                       9
<PAGE>

The Company's bank financing agreement provides a $10 million revolving line of
credit through December, 1999.  Interest on loans is charged at the prime rate
or, at the option of the Company, at the Eurodollar rate plus a rate in a range
of 1% to 2% depending on the financial leverage of the Company.  In addition,
the Company pays a 1/4% commitment fee on the unused line of credit.

Management believes that the funding needs of the Company for operating working
capital and capital expenditures will continue to be met through income from
operations and financing available under its line of credit.

YEAR 2000 COMPLIANCE
--------------------

Year 2000 issues are the result of computer programs that were written using two
digits rather than four to define the applicable year.  If the Company's
computer programs with date sensitive functions are not year 2000 compliant,
they may recognize a date using "00" as the year 1900 rather than the year 2000.
This could result in a system failure or miscalculations causing disruptions of
operations, including, an inability to process transactions, send invoices or
engage in other normal business activities.

The Company has identified its Year 2000 risks in three categories:  internal
business software, internal non-information technology software, and external
vendor compliance.

Internal Information Technology
-------------------------------

During 1998, as part of a modernization program intended to improve productivity
and increase profitability by upgrading data processing, integrating systems and
enhancing internal reporting, the Company purchased an ERP system which includes
software which the vendor has represented to be Year 2000 compliant.  The total
estimated hardware, software, installation and training cost of the integrated
ERP system, of which Year 2000 compliance is a by-product, is $6.7 million, of
which $6.6 million has been incurred through the third quarter, primarily funded
through operating cash flow.  The Company substantially completed the
implementation of the system during the second quarter of 1999.  With this
implementation, the Company believes its internal information technology systems
to be in substantial compliance. Contingency plans are being developed for areas
where management considers there may be some risk to modify certain of the major
existing internal information technology systems to be Year 2000 compliant.

Internal Non-Information Technology
-----------------------------------

The Company has assessed the Year 2000 compliance of its internal non-
information software and of the technology embedded in such systems as security,
telecommunications and building systems by contacting the providers of such
systems.  Written assurance of Year 2000 compliance has been received from
substantially all providers.

                                       10
<PAGE>

External Vendor Compliance
--------------------------

The Company has identified and contacted its major suppliers, service providers
and contractors ("vendors") to determine the extent of their Year 2000
compliance.  The process is substantially complete.  To the extent that
responses were unsatisfactory, the Company has contingency plans in place, which
includes a number of measures such as, where necessary, changing the vendors to
those who have represented Year 2000 readiness, but cannot be assured that it
will be successful in finding alternative vendors.  In the event that a major
vendor's written assurance of Year 2000 compliance becomes questionable and the
Company does not replace it with a new vendor, its business could be materially
adversely affected.  The Company is formulating a contingency plan for major
vendors' Year 2000 non-compliance.

FORWARD-LOOKING INFORMATION
---------------------------

From time to time, the Company or its representatives may have made or may make
forward-looking statements, orally or in writing.  Such forward-looking
statements may be included in, but, not limited to, press releases, oral
statements made by or with the approval of an authorized executive officer, or
in this report or other filings made by the Company with the Securities and
Exchange Commission.  The words or phrases "trend," "expect," "grow," "will,"
"could," "likely result," "planned," "continued," "anticipated," "estimated,"
"projected," "scheduled," "could have," "intended," "believes," "continuing,"
"considers," "may be," "assessed," "contingency" or similar expressions are
intended to identify "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995.  The Company wishes to ensure
that such statements are accompanied by meaningful cautionary statements, so as
to maximize to the fullest extent possible the protections of the safe harbor
established in the said Act.  Accordingly, such statements are qualified in
their entirety by reference to and are accompanied by the following discussion
of certain important factors that could cause actual results to differ
materially from such forward-looking statements.

Investors should also be aware of factors that could have an impact on the
Company's business or financial position or performance.  These include
possible: pressures on revenues resulting, for example, from customer
consolidations or changes in customer buying patterns; intensified competition
resulting, for example, from distributor consolidations or pricing pressures
from distributors able to benefit from economies of scale or other operating
efficiencies; disruptions in services or systems on which the Company is
dependent, such as by truckers in deliveries from its suppliers, by UPS or other
common carriers in deliveries to its customers, by its catalog printers or in
telecommunication services, or relating to its ERP or other computer systems or
Year 2000 issues (including regarding costs, scheduling, implementation, vendor

                                       11

compliance, and plans and expectations regarding such); unfavorable outcomes of
litigation to which the Company may become a party; and other factors detailed
from time to time in the Company's Securities and Exchange Commission filings or
other readily available or generally disseminated writings.  The risks
identified here are not all inclusive.  Reference is also made to other parts of
this report and the Company's most recent Annual Report on Form 10-K that
include additional information concerning factors that could adversely impact
the Company's business or financial position or performance.  Moreover, the
Company operates in a changing and very competitive business environment.  New
risks may emerge from time to time, and it is not possible for management to
predict all risk factors, nor can it necessarily identify or assess the impact
of all such factors on the Company or the extent to which any factor or
combination of factors may cause actual results to differ materially from those
contained in any forward-looking statements.  Accordingly, forward-looking
statements should not be relied upon as a prediction of actual results.
