Note 5:  Net Income per Common Share

A reconciliation between the numerators and denominators of the basic and
diluted income per share computation for net income follows:

                                             Three Months
                                                Ended
                                             September 30,

Weighted average common and
  potential common shares

Diluted income per share                   0.19        0.15

For the three months ended September 30, 1999, 220 employee stock options were
not included in the net income per share calculation because their effect would
have been anti-dilutive.  For the three months ended September 30, 1998, all
employee stock options were included.

Note 6:  Comprehensive Income

The Company has no items of other comprehensive income, therefore there is no
difference between the Company's comprehensive income and net income.

Note 7:  Reclassifications

Certain reclassifications have been made to the prior consolidated financial
statements to conform to the current presentation.


Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations


LIQUIDITY AND CAPITAL RESOURCES:

The Company's ability to generate cash from operations is considered adequate
to cover both short-term and long-term liquidity.  In addition, the Company had
cash and both short and long-term investments which totaled $23.1 million and
$23.3 million at September 30 and June 30, 1998, respectively.  All of these
investments are highly liquid.  The Company also has sufficient lines of credit
available should any additional funds be required.

Working capital increased to $51.5 million at September 30, 1999 from $49.5
million at June 30, 1999. The increase in short-term investments to $10.8
million at September 30, 1999 from $7.4 million at June 30, 1999 was due to a
shift of funds from long-term investments.  Receivables decreased to $25.5
million at September 30, 1999 from $27.0 million at June 30, 1999, this was the
result of the timing of cash receipts along with a higher sales level for the
quarter ending June 30, 1999 compared to the quarter ending September 30, 1999.
Inventory decreased to $27.9 million from $29.6 million, and the total of
drafts payable, accounts payable and accrued merchandise purchases decreased
$2.9 million comparing the same periods.  This was primarily due to the timing
of merchandise purchases and was not the result of a change in the trend of
business.

RESULTS OF OPERATIONS:

Net sales remained virtually the same for the three months ended September 30,
1999, compared with the same period in the prior year, excluding the minor
effect of the sales from CDC Products Corp. (CDC) acquired on November 19,
1998.  While sales were flat, there were some significant changes in several of
our segments.  Increased demand led to a 25% increase in sales of organic
intermediates and colorants.  Sales to the generic pharmaceutical industry, a
major component of the pharmaceutical biochemicals and nutritionals segment,
more than doubled due primarily to sales of one product occurring in the first
quarter of this year compared to later quarters last year, and the introduction
of several new products.  These increases were offset by a reduction of sales
of a product in our pharmaceutical intermediates and custom manufacturing
segment.  We anticipate these sales to occur in the second and third quarters
of this year.

Volume increased 27%.  The greater increase in volume than in sales is the
result of the change in mix of business.  The pharmaceutical product whose
sales decreased is a higher priced product, while the products whose sales
increased are lower priced, causing the differential.

Gross margins increased significantly in 1999 to 14.3% (net of the impact of
CDC) from 12.0% in 1998.  The aforementioned change in mix of business,
especially relating to the reduction in sales of the pharmaceutical product
(which are lower margin sales) caused the increase.

Selling, general and administrative expenses increased $553,000, or 17%
compared to the same period last year.  The inclusion of CDC in the
consolidated financial statements accounted for $370,000 or 67% of this
increase, and a significant legal bill relating to the successful defense of a
patent infringement case accounted for $240,000.  In addition there were slight
increases in compensation and selling expenses.  Offsetting some of the above
increases was a decrease in consulting fees.

Other income decreased to $275,000 for the three months ended September 30,
1999 from $654,000 for the same period last year.  Interest on investments
decreased approximately $100,000 due to a significant decrease in the total of
cash and cash equivalents, short-term investments and long-term investments.
The decrease in cash available for investment was primarily due to the
Company's ongoing stock repurchase program and the acquisition of CDC.  Royalty
income, for sales to European customers, from one of the Company's subsidiaries
totaled $150,000 in the quarter ended September 30, 1998 compared to $13,000
for the current period.  The subsidiary is now selling products directly to
most of its European customers and consequently the royalties will continue to
decrease considerably.  In addition, a loss on marketable securities of $73,000
was recorded during the three months ended September 30, 1999 compared to a
gain of $47,000 during the same period last year.

The effective tax rate decreased to 38.8% for the three months ended September
30, 1999 from 40.7% for the same period last year.  In comparing these periods,
the effective tax rates are within the range of the Company's traditional
levels.

IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

In June 1999, the Financial Accounting Standards Board (FASB) issued Statement
of Financial Accounting Standards (SFAS) No. 137, "Accounting for Derivative
Instruments and Hedging Activities-Deferral of the Effective Date of FASB
Statement No. 133."  SFAS 137 amends SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities," which was issued in June 1998.  SFAS 137
defers the effective date of SFAS 133 to all fiscal quarters of fiscal years
beginning after June 15, 2000.  Earlier application is permitted.  SFAS 133
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts and for
hedging activities.  It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and
measures those instruments at fair value.  While management has not determined
the impact of the new standard, it is not expected to be material.

YEAR 2000 DISCLOSURE

During fiscal 1998, the Company determined that it needed to modify or replace
significant portions of its customized software so that its information systems
would function properly with respect to dates in the year 2000 and beyond. In
addition, the Company has assessed all the third party hardware and software it
uses for Year 2000 compliance. The Company also has initiated discussions with
its significant suppliers, customers, and financial institutions to ascertain
that those parties have appropriate plans to remediate Year 2000 issues where
their systems interface with the Company's systems or otherwise impact its
operations. The Company is continuing to monitor the extent to which its
operations are vulnerable should those organizations fail to properly
remediate their computer systems. The Company's Year 2000 team includes
both internal and external staff. The team's activities are designed to
ensure that there is no adverse effect on the Company's core business
operations and that transactions with customers, suppliers, and financial
institutions are fully supported.  The Company has completed implementation of
its Year 2000 initiative.  All significant computer and business systems are
now compliant.  While the Company believes its planning efforts are adequate to
address its Year 2000 concerns, there can be no guarantee that the systems of
other companies on which the Company's systems and operations rely will be
converted on a timely basis. The Company believes it unlikely that there will
be a material effect on the Company.

The total cost of the Company's Year 2000 initiative was approximately
$100,000.
