                        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements of Isonics
Corporation and Subsidiaries (the "Company" or "Isonics") as of October 31,
1999, and for the three and six months ended October 31, 1999, and 1998, have
been prepared on the same basis as the annual audited financial statements.
In the opinion of management, such unaudited information includes all
adjustments (consisting only of normal recurring accruals) necessary for a
fair presentation of this interim information. Operating results and cash
flows for interim periods are not necessarily indicative of results for the
entire year. The information included in this report should be read in
conjunction with our audited financial statements and notes thereto included
in our Annual Report on Form 10-KSB for the year ended April 30, 1999.

NET INCOME (LOSS) PER SHARE

Net income (loss) per share is based on the weighted average number of common
and common equivalent shares outstanding during the period. Common equivalent
shares include common stock options and warrants. Basic net income (loss) per
share is computed by dividing net income (loss) by the number of weighted
average common shares outstanding. Diluted net income (loss) per share
reflects potential dilution from outstanding stock options and warrants using
the treasury stock method. A total of approximately 7.550 million outstanding
stock options and warrants have been excluded from the diluted earnings per
share calculation as the inclusion would be antidilutive.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTES PAYABLE - RELATED PARTIES

Two notes were issued to each of the sellers of Chemotrade GmbH and
subsidiary as consideration for a portion of the purchase price. The first
note was repaid in August 1998. A partial payment of approximately $550
thousand was paid in June 1999, on the second note. The remaining balance of
approximately $343 thousand, including interest, was refinanced and is now
payable July 31, 2000. The new interest rate is 12% per annum. In addition,
approximately 70,000 warrants (five-year, $3.00 strike price) were issued in
June 1999, in conjunction with the refinancing. The fair value of these
warrants was determined to be $157 thousand, using the Black-Scholes option
pricing model, and this value is being amortized as additional interest
expense over the revised term of the note.

RESTRUCTURING AND OFFICE CLOSURE COSTS

On October 31, 1998, the Company announced a restructuring of its operations
and relocation of its headquarters from San Jose, California to Golden,
Colorado, the location of the Company's subsidiary, Interpro. As of October
31, 1999, the only significant restructuring cost remaining is the lease
payments on the former San Jose office. This liability, net of sublease
income, is estimated to be approximately $54 thousand, and will be paid over
the next four years.

SIGNIFICANT CUSTOMERS

At October 31, 1999, one customer accounted for 12% of total accounts
receivable. A different customer accounted for approximately 17% of net
revenues during the three months ended October 31, 1999, and the same
customer accounted for approximately 10% of net revenues during the six
months ended October 31, 1999. A different customer accounted for
approximately 25% of net revenues during the six months ended October 31,
1998. There were no significant customers during the three months ended
October 31, 1998.

PREFERRED STOCK ISSUANCE

On July 29, 1999, the Company completed a private placement financing to
accredited investors and certain creditors valued in total at $2.7 million.
The Company issued 1,830,000 units, each consisting of one share of Series A
Convertible Preferred Stock and one warrant. The Company received $2,250,000
cash proceeds and converted $495,000 of long-term debt and other obligations.
Each share of the Series A Convertible Preferred Stock is convertible into
one share of the Company's common stock at a conversion price of $1.50. The
liquidation preference for the Series A Convertible Preferred Stock is $1.50.
Each warrant allows the investor to purchase one share of the Company's
common stock for $3.75 through July 29, 2002.

In addition to converting $495,000 of existing debt and other obligations
into equity as part of the private placement, the Company:

-    issued 500,000 warrants to purchase shares of the Company's common stock to
     an investment banker for service rendered in this placement. The warrants
     are exercisable at $3.75 per share through July 29, 2002.
-    extended the payment due date for the remaining balance on the Chemotrade
     acquisition note to July 2000 and extended the payment due date for certain
     unsecured promissory notes to January 2000.

SALE OF DEPLETED ZINC BUSINESS

On December 1, 1999, we sold our depleted zinc business to Eagle-Picher
Technologies, LLC. ("Eagle-Picher") for approximately $8.2 million cash of which
$6.7 million was paid on December 1, 1999. Additionally, we signed a long-term
isotope supply agreement with Eagle-Picher, and Eagle-Picher will supply us with
200 kilograms of Silicon-28 in 2000. We also gave Eagle-Picher a warrant to
obtain 4,000,000 shares of our common stock.

THE STATEMENTS CONTAINED IN THIS REPORT ON FORM 10-QSB THAT ARE NOT PURELY
HISTORICAL ARE FORWARD LOOKING STATEMENTS WITHIN THE MEANING OF SECTION 27A
OF THE SECURITIES ACT OF 1933 AND SECTION 21E OF THE SECURITIES EXCHANGE ACT
OF 1934, INCLUDING STATEMENTS REGARDING OUR EXPECTATIONS, HOPES, INTENTIONS
OR STRATEGIES REGARDING THE FUTURE. FORWARD LOOKING STATEMENTS INCLUDE:
STATEMENTS REGARDING FUTURE PRODUCTS OR PRODUCT DEVELOPMENT; STATEMENTS
REGARDING FUTURE SELLING, GENERAL AND ADMINISTRATIVE COSTS AND RESEARCH AND
DEVELOPMENT SPENDING AND OUR PRODUCT DEVELOPMENT STRATEGY; AND STATEMENTS
REGARDING FUTURE CAPITAL EXPENDITURES AND FINANCING REQUIREMENTS. ALL FORWARD
LOOKING STATEMENTS INCLUDED IN THIS DOCUMENT ARE BASED ON INFORMATION
AVAILABLE TO US ON THE DATE HEREOF, AND WE UNDERTAKE NO OBLIGATION TO UPDATE
ANY SUCH FORWARD LOOKING STATEMENTS. IT IS IMPORTANT TO NOTE THAT OUR ACTUAL
RESULTS COULD DIFFER MATERIALLY FROM THOSE IN SUCH FORWARD-LOOKING STATEMENTS.

OVERVIEW

Founded in 1992, Isonics Corporation ("Isonics" or the "Company") is a
specialty chemical and advanced materials company, which develops and
commercializes products based on stable isotopes. Stable isotopes are ultra
pure materials engineered at the molecular level to provide enhanced
performance properties in semiconductors, lasers and high performance
lighting and energy production. Stable isotopes are also widely used in basic
research, pharmaceutical development and drug design, as well as in medical
diagnostics and imaging. By replacing materials traditionally used in these
industries with isotopically engineered versions of the same materials,
product performance, safety, and economics can be enhanced significantly.
Using state-of-the-art technology, we produce a wide range of enriched stable
isotopes, which are then converted into products, which meet the specialized
needs of our customers.

Originally, our core business was the production and supply of depleted zinc
("DZ"), a non-radioactive stable isotope, to the energy industry. In fiscal
1996, we expanded our business scope to include development of isotopically
engineered materials for the medical research, medical diagnostic and
semiconductor industries. The acquisition of Chemotrade GmbH ("Chemotrade")
in 1998 added radioactive isotopes to our available products. As a result of
the sale of our depleted zinc business in December 1999, (see discussion
below) our revenues in the future will depend on our success in developing
and selling products in the semiconductor and stable and radioactive isotope
markets.

International Process Research Corporation ("Interpro", doing business as
Colorado Minerals Research Institute) is a contract research and development
and materials processing company and is developing new, lower cost
technologies to better meet our customers' needs. Interpro generates the
majority of its revenues from contract research and process development
engagements.

Chemotrade is headquartered in Dusseldorf, Germany, and its subsidiary is
located in Leipzig, Germany. Chemotrade is a value-added re-seller of stable
and radioactive isotopes. It supplies radioactive isotopes for pharmaceutical
and industrial research as well as for industrial and medical imaging,
calibration sources and for brachytherapy applications. Chemotrade also
distributes calibration sources, manufactured by duPont with Chemotrade
supplied radioactive isotopes, in Germany and other European countries.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

Chemotrade supplies various stable isotope labeled compounds for
pharmaceutical research and drug design, as well as oxygen-18 for use in
producing a radioisotope used in positron emission tomography. Chemotrade's
market is primarily Europe but frequently sales are made to North America and
Asia.

Prior to June 1998, substantially all of our net revenues in any particular
period were attributable to a limited number of customers and sales of
depleted zinc and other stable isotopes. We have historically operated with
little backlog. With the acquisition of Chemotrade we added radioisotopes to
our product mix, and consistent with our historical experience, our quarterly
results have been materially affected by the size, timing and quantity of
orders and product shipments during a given quarter.

On December 1, 1999, we sold our depleted zinc business to Eagle-Picher
Technologies, LLC ("Eagle-Picher") for approximately $8.2 million cash of
which $6.7 million was paid on December 1, 1999. Additionally, we signed a
long-term isotope supply agreement with Eagle-Picher, and Eagle-Picher will
supply us with 200 kilograms of Silicon-28 in 2000. We also gave Eagle-Picher
a warrant to obtain 4,000,000 shares of our common stock.

As a result, we anticipate lower revenues in future quarters and a lost or
delayed sale of radioisotopes could have a significant impact on our
operating results for a particular period, and such fluctuations could
materially and adversely affect the our business, financial condition and
results of operations.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

NET REVENUES

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, revenues will be decreased on an annual basis by
approximately $6.0 million dollars. The impact on the fiscal year ended April
30, 2000 should be somewhat less as the sale occurred seven months into the
fiscal year.

Net revenues for the three months ended October 31, 1999, were $4.460
million, an increase of approximately 20% over $3.706 million for the same
period in the prior fiscal year. The increase is primarily because our net
revenues from stable isotopes sales increased approximately $1.559 million
thousand for the three months ended October 31, 1999, to approximately $3.282
million. Net revenues from radioisotope sales decreased approximately $526
thousand for the three months ended October 31, 1999, to approximately $794
thousand. Net revenues from contract research and development services sales
as well as other sources of sales decreased approximately $319 thousand for
the three months ended October 31, 1999, to approximately $384 thousand. Net
revenues from stable isotope and radioisotope sales varied considerably from
the same quarter in the prior fiscal year primarily because of timing of
large depleted zinc and radioisotope sales orders and shipments.

Net revenues for the six months ended October 31, 1999, were $7.544 million,
a decrease of approximately 1% from $7.639 million for the same period in the
prior fiscal year. The decrease is primarily because our net revenues from
contract research and development engagements and other sources of sales
decreased approximately $916 thousand for the six months ended October 31,
1999, to approximately $717 thousand. Net revenues from radioisotope sales
also decreased approximately $437 thousand for the six months ended October
31, 1999, to approximately $1.744 million. These decreases were offset by net
revenues from stable isotope sales, which increased approximately $1.258
thousand for the six months ended October 31, 1999, to approximately $5.083
million. Net revenues from stable isotopes and radioisotope sales varied
because of the timing and size of large depleted zinc and radioisotope sales
orders and shipments.

GROSS MARGIN

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, gross margin will be decreased on an annual basis by
approximately $1.0 million dollars. The impact on the fiscal year ended April
30, 2000 should be somewhat less as the sale occurred seven months into the
fiscal year. As a percentage of revenues gross margin should not change
significantly.

Gross margin for the three months ended October 31, 1999, increased to
approximately 22.2% of net revenues from approximately 13.8% for the same
period in the prior fiscal year. The increase is primarily because of a
change in product mix sold during the quarter as discussed above. Gross
margin for the six months ended October 31, 1999, increased to approximately
22.2% of net revenues from approximately 19.1% for the same period in the
prior fiscal year. The increase is primarily because of a change in product
mix sold during the the six month period as discussed above.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, selling, general and administrative expenses will be
decreased on an annual basis by approximately $100 thousand dollars. The
impact on the fiscal year ended April 30, 2000 should be somewhat less as the
sale occurred seven months into the fiscal year. As a percentage of revenues
selling, general and administrative expenses should increase, as revenues
will be significantly lower.

Selling, general and administrative expenses increased on a dollar basis to
approximately $945 thousand, or approximately 21.2% of net revenues for the
three months ended October 31, 1999, from $936 thousand, or 25.3% of net
revenues in the comparable period of the prior year. The dollar increase for
the quarter ended October 31, 1999, was primarily attributable to increased
usage of professional services including legal, business development and
accounting services, while the percentage decrease was primarily caused by
higher revenues.

We anticipate that selling, general and administrative expenses will
generally remain stable or decrease in absolute dollars because our move to
Colorado is complete, and because of cost cutting measures implemented
throughout the Company, specifically the consolidation of overhead functions
in Golden with our subsidiary, Interpro. However, as a percentage of net
revenues SG&A costs will still vary because of the timing and amount of
future revenues.

Selling, general and administrative expenses increased on a dollar basis to
approximately $1,830 thousand, or approximately 24.3% of net revenues for the
six months ended October 31, 1999, from $1,618 thousand, or 21.2% of net
revenues in the comparable period of the prior year. The dollar increase for
the six months ended October 31, 1999, was primarily attributable to
increased usage of professional services including legal, business
development and accounting services, while the percentage increase was
primarily caused by the same factors.

RESEARCH AND DEVELOPMENT

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, research and development expenses will not be significantly
affected. However, as a percentage of revenues research and development
expenses should increase, as revenues will be significantly lower.

Research and development expenses decreased by approximately $184 thousand,
or approximately 47%, to $205 thousand for the quarter ended October 31,
1999, from $389 thousand for the comparable period in fiscal 1998, while
declining on a percentage basis to approximately 4.6% of net revenues from
approximately 10.5%. The dollar decrease during the quarter ended October 31,
1999, was primarily because of decreased staffing and material costs
associated with the development of isotopically pure silicon wafers and
development costs incurred at Interpro.

<PAGE>

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

Research and development expenses decreased by approximately $380 thousand,
or approximately 53%, to $332 thousand for the six months ended October 31,
1999, from $712 thousand for the comparable period in fiscal 1998, while
declining on a percentage basis to approximately 4.4% of net revenues from
approximately 9.3%. The dollar and percentage decrease during the six months
ended October 31, 1999, was primarily because of decreased staffing and
material costs associated with the development of isotopically pure silicon
wafers and development costs incurred at Interpro.

We believe that the development and introduction of new product applications
is critical to our future success and we expect that research and development
expenses will increase (as measured in dollars), in the near term because of
the timing of material usage and outside services, but will likely continue
to vary as a percentage of revenues because of the timing and amount of
future revenues.

RESTRUCTURING AND OFFICE CLOSURE

On October 31, 1998, we announced a restructuring of our operations and
relocation of our headquarters to Golden, Colorado, the location of our
subsidiary, Interpro. We recorded a $708 thousand charge in connection with
the restructuring.

As of October 31, 1999, the only significant restructuring cost remaining is
the lease payments on the former San Jose, California office, which has been
sublet for the remaining term of our lease. The net liability is estimated to
be approximately $54 thousand and will be incurred over the next four years.
The $66 thousand expense in the six months ending October 31, 1999 was
primarily related to moving costs incurred by two senior executives.

OTHER INCOME (EXPENSE), NET

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, interest expense will be significantly lower as several
notes payable were paid with a portion of the cash proceeds. The impact as a
percentage of revenues of other income (expense), net is not readily
determinably as both the expense and revenues will be significantly lower.

Other income (expense), net includes interest expense, amortization of debt
issuance costs and the fair value of warrants issued in connection with the
debt, and foreign currency gains and losses. Other income, net increased by
approximately $197 thousand, to $16 thousand, for the quarter ended October
31, 1999, from other (expense), net of approximately $181 thousand, for the
comparable period of the previous fiscal year. The increase in interest
expense of approximately $10 thousand, was offset by an increase in other
income of approximately $112 thousand due to a favorable settlement of an
outstanding contingency and a reduction in foreign currency exchange losses
of approximately $92 thousand.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

Other (expense), net decreased by approximately $170 thousand, to $63
thousand, for the six months ended October 31, 1999, from other (expense),
net of approximately $233 thousand, for the comparable period of the previous
fiscal year. The increase in interest expense of approximately $58 thousand,
was offset by an increase in other income of approximately $112 thousand due
to a favorable settlement of an outstanding contingency and a reduction in
foreign currency exchange losses of approximately $96 thousand.

INCOME TAXES

We realized a gain on the sale of our depleted zinc business of approximately
$1.0 million. The tax effect of this sale, net of any tax loss carryforwards
available as yet can not be determined.

There was no income tax expense for the quarters ended October 31, 1999, and
October 31, 1998. Income tax expense for the six months ended October 31,
1999 and 1998, relates to income generated by our Germany-based subsidiary,
Chemotrade. We have recorded a valuation allowance against our deferred tax
assets as realization of the benefits is not assured.

LIQUIDITY AND CAPITAL RESOURCES

As a result of the sale of the depleted zinc business to Eagle-Picher on
December 1, 1999, liquidity has been significantly improved.

Our principal sources of funding have been cash from borrowed funds and sales
of preferred stock. We used cash in operating activities of approximately
$1.385 million and generated cash of $62 thousand, during the six months
ended October 31, 1999, and 1998, respectively. Cash used in operating
activities during the six months ended October 31, 1999 was principally the
result of a net loss of approximately $616 thousand, and an increase in
operating working capital. Cash generated by operating activities during the
six months ended October 31, 1998, was principally the result of a net loss
of $1.834 million, reduced by non-cash charges and decreases in operating
working capital.

Our investing activities used cash of $654 thousand for the six months ended
October 31, 1998, primarily for purchases of property and equipment. Cash
amounting to $546 thousand, was also used during the six months ended October
31, 1998 for the purchase of our subsidiary Chemotrade.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

Financing activities generated cash of $1.246 million during the six months
ended October 31, 1999, and used cash of $144 thousand during the comparable
period of the previous fiscal year. Cash provided by financing activities
during the six months ended October 31, 1999, resulted primarily from the
issuance of convertible preferred stock for cash of $2.250 million, and
proceeds from the issuance of long-term debt of $75 thousand. Net repayments
on the revolving line of credit of $298 thousand, and repayments of debt of
$781 thousand were the primary uses of cash during the six month period ended
October 31, 1999. Cash used during the six months ended October 31, 1998,
resulted primarily from repayments of debt of $1.640 million, offset by net
borrowings on the revolving line of credit of $1.009 million and proceeds of
$500 thousand from the issuance of long-term debt.

At October 31, 1999, we had approximately $313 thousand of cash and cash
equivalents, a decrease of approximately $139 thousand, compared to $452
thousand as of April 30, 1999. At October 31, 1999, we had positive working
capital of approximately $226 thousand, an increase of approximately $2.543
million from April 30, 1999. The increase is primarily the result of proceeds
from the issuance of preferred stock in July 1999.

During the six months ended October 31, 1999, we issued approximately $2.745
million in convertible preferred stock. Cash proceeds totaled approximately
$2.250 million and conversion of notes payable and other obligations to
preferred stock totaled approximately $0.495 million. This convertible
preferred stock placement is described in detail in the Form 8-K we filed on
August 11, 1999.

At October 31, 1999, we were in default of our borrowing agreements with
Coast Business Credit ("Coast"), and at that date had approximately $215
thousand of outstanding borrowings. We have used some of the proceeds of the
depleted zinc business sale describe above to pay off the Coast borrowings
and our relationship with Coast has been terminated. We currently have no
borrowing agreements in place with any lenders.

We believe that the cash proceeds from the recent sale of our depleted zinc
business will be sufficient for us to meet our cash needs for the next twelve
months. However, our long-term capital requirements will only be met if we
are able to generate profits from operations and positive cash flows.

FACTORS THAT MAY AFFECT FUTURE RESULTS

In evaluating our business, prospective investors should carefully consider
the following factors in addition to the other information presented in this
report and in our other reports filed with the SEC that attempt to advise
interested parties of the risks and factors that may affect our business.

Following the sale of our depleted zinc business, our primary risk is our
reliance on products that have to date not produced significant revenues. We
operate with little backlog and a significant portion of our net revenues
have been, and we believe will continue to be, derived from a limited number
of orders that are processed and shipped in the same quarter in which the
orders are received. These orders being primarily for radioisotopes. The
timing of such orders and their fulfillment has caused, and is likely to
continue to cause, material fluctuations in our operating results. Our
expense levels are relatively fixed, and as has been the case in prior
quarters, these factors will affect our operating results for future periods.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

RELATIONSHIP WITH CERTAIN SUPPLIERS AND AVAILABILITY OF RAW MATERIALS

We depend on an isotope enrichment plant, located in Russia, which is owned
by the Ministry of Atomic Energy of the Russian Federation (the "Ministry"),
which is part of the cabinet of the government of the Russian Federation, for
most of our stable and radioisotopes. We signed an agreement with the
commercial department of the Ministry to purchase certain isotope separation
services through 2001. Disruption or termination of services provided by the
Ministry could have a material and adverse affect upon our financial
condition and results of operations.

OPERATIONS IN RUSSIA AND THE REPUBLIC OF GEORGIA

Operations in Russia and the republic of Georgia ("Georgia") entail certain
risks. Recently, the former republics of the Soviet Union including Georgia
have experienced political, social and economic change as they sought
independence from the former central government in Moscow, and certain of the
republics, including Russia and Georgia, have attempted to transition from a
central controlled economy toward a market-based economy. These changes have
involved, in certain cases, armed conflict. There can be no assurance that
political or economic instability in these republics will not continue or
worsen. The supply of stable isotopes could be directly affected by
political, economic and military conditions in Russia and Georgia.
Accordingly, our operations could be materially adversely affected if
hostilities in Russia should occur, if trade between Russia or Georgia and
the United States were interrupted, if political conditions in Russia or
Georgia disrupt transportation or processing concerning our goods, if laws or
government policies concerning foreign business operations in Russia or
Georgia change substantially, or if tariffs are introduced.

CUSTOMER CONCENTRATION

Historically, substantially all of our net revenues in any particular period
have been attributable to a limited number of customers. Consistent with our
historical experience, our quarterly results are expected to be affected
materially by the level of orders received and product shipments by us during
such periods. This factor pertains primarily to radioisotope sales. There can
be no assurance that our current customers will continue to purchase
products. A decrease in or loss of orders from one or more major radioisotope
customers would have a material and adverse effect on our financial condition
and results of operations.

MANAGEMENT OF GROWTH

We have experienced periods of rapid growth that have placed a significant
strain on our financial and managerial resources. Our ability to manage
growth effectively, particularly given our changing scope of operations, will
require us to continue to implement and improve our management, operational,
and financial information systems, as well as to develop the management
skills of our personnel and to train, motivate and manage our employees. Our
failure to effectively manage growth could have a material adverse effect on
our business, financial condition and results of operations.

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

DEPENDENCE ON KEY PERSONNEL

Our future success will depend in significant part upon the continued service
of our key technical, sales and senior management personnel, including James
E. Alexander, our President and Chief Executive Officer, Boris Rubizhevsky,
our Senior Vice President, Isotope Production and Supply, Robert Cuttriss,
President of Interpro, and Herbert Hegener, Managing Director of Chemotrade.
We maintain $1 million of key man life insurance on the lives of Messrs.
Alexander, Rubizhevsky and Cuttriss and all are covered by employment
agreements with the Company extending through September 2001, 2001, and 2003,
respectively. Mr. Hegener is covered by an employment agreement with the
Company extending through the year 2001. We believe that our future success
will depend in large part upon our ability to attract and retain qualified
personnel for our operations. The failure to attract or retain such persons
could materially adversely affect our business, financial condition and
results of operations.

DATES FOLLOWING DECEMBER 31, 1999 AND BEYOND (THE "YEAR 2000 PROBLEM")

Many existing computer systems and applications, and other devices, use only
two digits to identify a year in the date field, without considering the
impact of the upcoming change in the century. Such systems and applications
could fail or create erroneous results unless corrected. We rely on our
internal financial systems and external systems of business enterprises such
as customers, suppliers, creditors, and financial organizations both
domestically and globally, directly and indirectly for accurate exchange of
data. We have evaluated such systems and have implemented and tested
appropriate changes to our systems to ensure Y2K compatibility. We believe
the cost of addressing any unidentified issues with the Year 2000 Problem
will not have a material adverse affect on our results of operations or
financial position. Additionally, based on information received from our key
third party vendors, we have evaluated the potential impact of a Year 2000
problem on the part of our important third party vendors and have found none.
However, even though the Year 2000 issue does not materially affect our
internal systems, we could be affected through disruption in the operation of
the enterprises with which we interact.

VOLATILITY OF STOCK PRICE

The trading price of our securities has been subject to wide fluctuations in
response to quarter-to-quarter variations in operating results, announcements
of technological innovations or new products by us or our competitors, and
other events or factors. In addition, the stock market has experienced wide
price and volume fluctuations, which have at times been unrelated to the
operating performance of the companies whose securities are traded. These
broad market fluctuations may adversely effect the market price of our common
stock and common stock warrants.

ITEM 6: EXHIBITS AND REPORTS ON FORM 8-K

One report on Form 8-K was filed during the quarter ended October 31, 1999,
on August 11, 1999, describing our sale convertible preferred stock.

No other reports on Form 8-K were filed during the quarter ended October 31,
1999. However on December 15, 1999, we filed a Form 8-K describing the sale
of our depleted zinc business to Eagle-Picher Technologies, LLC. for
approximately $8.2 million cash of which $6.7 million was paid on December 1,
1999. Additionally, we signed a long-term isotope supply agreement with
Eagle-Picher, and Eagle-Picher will supply us with 200 kilograms of
Silicon-28 in 2000. We also gave Eagle-Picher a warrant to obtain 4,000,000
shares of our common stock.
