     The accompanying  interim financial  statements are unaudited and have been
prepared by the Company  pursuant to the rules and regulations of the Securities
and  Exchange   Commission   ("SEC")  regarding  interim  financial   reporting.
Accordingly,  they do not include all of the information and footnotes  required
by generally accepted accounting  principles for complete financial  statements,
and  therefore  these  consolidated  financial  statements  should  be  read  in
conjunction with the Company's audited consolidated  financial  statements,  and
the notes  thereto,  for the year ended  September  30, 2001.  In the opinion of
management,  the consolidated  financial  statements for the three month periods
ended  December 31, 2001 and 2000 include all normal and  recurring  adjustments
which are  necessary  for a fair  presentation  of the  results  of the  interim
periods. The results of operations for the three month period ended December 31,
2001 are not necessarily indicative of the results for the year ending September
30, 2002.

plus 200 to 300 basis points, as elected by the Company,  depending upon certain
financial  ratios.  The  line is  collateralized  by  inventories  and  accounts
receivable and requires the Company to maintain certain  financial  ratios.  The
Company  pays a fee  equal  to 12.5 to 50 basis  points,  depending  on  certain
financial  ratios,  on the unused portion of the line of credit.  As of December
31, 2001 and September 30, 2001,  interest on the entire outstanding balance was

(7)  NEW ACCOUNTING PRONOUNCEMENTS

     In June 2001, the FASB issued Statements of Financial  Accounting Standards
("SFAS")  No. 141,  "Business  Combinations"  and No. 142,  "Goodwill  and Other
Intangible Assets." Under the new rules,  goodwill (and intangible assets deemed
to have  indefinite  lives) will no longer be  amortized  but will be subject to
annual  impairment  tests in accordance  with the Statements.  Other  intangible
assets will continue to be amortized  over their useful lives.  The Company will
be  required  to apply  the new  rules on  accounting  for  goodwill  and  other
intangible   assets  beginning  in  the  first  quarter  of  fiscal  year  2003.
Application of the  non-amortization  provisions of the Statement is expected to
result in an  increase in net income of $77,000  (approximately  $.02 per share)
per year. The Company will perform the first of the required impairment tests of
goodwill and indefinite  lived  intangible  assets as of October 1, 2002 and has
not yet  determined  what the effect of these tests will be on the  earnings and
financial position of the Company.

     In  October  2001,  the FASB  issued  SFAS  No.  144,  "Accounting  for the
Impairment  or Disposal of  Long-Lived  Assets."  SFAS No. 144  supercedes  FASB
Statement No. 121,  "Accounting for the Impairment of Long-Lived  Assets and for
Long-Lived  Assets to Be Disposed Of" and also  supercedes  the  accounting  and
reporting   provisions  of  APB  Opinion  No.  30,  "Reporting  the  Results  of
Operations-Reporting  the Effects of  Disposal  of a Segment of a Business,  and
Extraordinary,  Unusual and Infrequently Occurring Events and Transactions," for
segments of a business to be disposed  of. Among its many  provisions,  SFAS No.
144 retains the fundamental requirements of both previous standards, however, it
resolves significant implementation issues related to FASB Statement No. 121 and
broadens the separate  presentation  of  discontinued  operations  in the income
statement  required by APB  Opinion  No. 30 to include a component  of an entity
(rather  than a segment  of a  business).  The  provisions  of SFAS No.  144 are
effective  for  financial  statements  issued for fiscal years  beginning  after
December  15,  2001,  with early  application  encouraged.  The Company does not
believe, based on current circumstances,  the effect of adoption of SFAS No. 144
will be material.

ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

     This Form 10-Q may contain "forward-looking statements," within the meaning
of Section 27A of the Securities Act of 1933, as amended,  and/or Section 21E of
the Securities  Exchange Act of 1934, as amended.  Those statements may include,
but are not limited to,  discussions  regarding the Company's intent,  belief or
current expectations with respect to (i) the Company's strategic plans; (ii) the
Company's future profitability;  (iii) the Company's capital requirements;  (iv)
industry  trends  affecting  the  Company's  financial  condition  or results of
operations;  (v) the Company's  sales or marketing  plans; or (vi) the Company's
growth  strategy.  Investors in the Company's  Common Shares are cautioned  that
reliance on any  forward-looking  statement  involves  risks and  uncertainties,
including  the risk factors  contained in Exhibit 99.1 to the  Company's  annual
report on Form 10-K for the year ended September 30, 2001.  Although the Company
believes that the assumptions on which the forward-looking  statements contained
herein are based are  reasonable,  any of those  assumptions  could  prove to be
inaccurate,  and as a result,  the  forward-looking  statements based upon those
assumptions also could be incorrect.  In light of the uncertainties  inherent in
any  forward-looking  statement,  the inclusion of a  forward-looking  statement
herein  should not be  regarded  as a  representation  by the  Company  that the
Company's plans and objectives will be achieved.

RESULTS OF OPERATIONS

THREE MONTHS ENDED  DECEMBER 31, 2001 COMPARED WITH THREE MONTHS ENDED  DECEMBER
31, 2000

     Total revenue for the three months ended December 31, 2001 increased  11.0%
to $6.0 million from $5.4 million for the three months ended  December 31, 2000.
The net increase of $597,000 was  primarily  due to the addition of contracts in
the service group, which increased service revenue to $3.6 million for the three
months  ended  December  31, 2001 from $3.1  million for the three  months ended
December 31, 2000.

     Total  cost of  revenue  for the  three  months  ended  December  31,  2001
increased  15.4% to $3.5  million  from $3.0  million for the three months ended
December  31,  2000.  Cost of services  revenue  increased  to 73.4% of services
revenue for the three  months  ended  December 31, 2001 from 72.4% for the three
months ended December 31, 2000.  Cost of product  revenue  increased to 34.5% of
product  revenue  for the three  months  ended  December  31, 2001 from 32.7% of
product revenue for the three months ended December 31, 2000, primarily due to a
change in product mix.

     Selling  expenses for the three months ended December 31, 2001 increased to
$778,000  from $776,000 for the three months ended  December 31, 2000.  Research
and development  expenses for the three months ended December 31, 2001 decreased
18.0% to $323,000  from  $394,000 for the three months ended  December 31, 2000,
primarily  as a result  of an  increase  in grant  reimbursements.  General  and
administrative  expenses for the three months ended  December 31, 2001 increased
33.8% to $1.0  million from  $761,000  for the three  months ended  December 31,
2000,  primarily  from  the  organizational  restructuring  of  our  preclinical
operation.

     Other expense was $25,000 for the three months ended  December 31, 2001, as
compared to other  expense of $135,000 for the three  months ended  December 31,
2000, primarily as a result of decreased interest expense due to the decrease in
debt.

     The Company's  effective  tax rate for the three months ended  December 31,
2001 was 40.0% as  compared to 45.1% for the three  months  ended  December  31,
2000,  primarily  due to the  utilization  of the tax  benefit  of  foreign  net
operating losses.


                                     - 8 -


LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 2001, the Company had cash and cash equivalents of $636,000
compared to cash and cash  equivalents  of $374,000 at September  30, 2001.  The
increase in cash resulted primarily from the Company's financing activities.

     The Company's net cash provided by operating activities was $14,000 for the
three months ended December 31, 2001 as compared to net cash used of $64,000 for
the first three months of fiscal 2000, primarily due to the decrease in accounts
receivable in the quarter ended  December 31, 2001.  The positive cash flow from
operations  during the three months ended December 31, 2001, was the result of a
net income of $247,000 plus non-cash  charges of $618,000 offset by a net change
of $(851,000) in operating assets and liabilities.

     Cash used by investing  activities  was $294,000 for the three months ended
December 31, 2001 as compared to $129,000  for the three  months ended  December
31, 2000.  This increase was primarily  due to the increase of  construction  in
progress at the  preclinical  site in  Evansville,  Indiana in the quarter ended
December 31, 2001.  Cash provided by financing  activities  for the three months
ended December 31, 2001 was $535,000, primarily due to the increased utilization
of the revolving line of credit.

     Total  expenditures by the Company for property and equipment were $294,000
and  $129,000   for  the  three  months  ended   December  31,  2001  and  2000,
respectively.  Expenditures  made  in  connection  with  the  expansion  of  the
Company's operating  facilities and purchases of laboratory  equipment accounted
for the largest portions of these expenditures. The Company also expects to make
other  investments  to expand its  operations  through  internal  growth and, as
attractive  opportunities arise, through strategic  acquisitions,  alliances and
joint  ventures.  During 2001,  the Company  signed a letter of intent to expand
facilities at its preclinical site in Evansville, Indiana. The commitment is for
approximately $2.5 million. Construction on the facilities expansion is expected
to be completed in December, 2002. The Company plans to obtain a mortgage with a
commercial lender to finance this construction.

     Based on its current  business  activities,  the Company believes that cash
generated from its operations and amounts available under its existing bank line
of credit will be sufficient to fund its anticipated working capital and capital
expenditure requirements.

     The Company has a revolving line of credit, which expires April 1, 2002 and
allows  borrowings  of  up  to  $3,500,000.  Interest  accrues  monthly  on  the
outstanding  balance at the bank's  prime rate minus 25 to plus 75 basis  points
(4.50% at December  31,  2001) or at the London  Interbank  Offered Rate (LIBOR)
plus 200 to 300 basis points, as elected by the Company,  depending upon certain
financial  ratios.  The  line is  collateralized  by  inventories  and  accounts
receivable and requires the Company to maintain certain  financial  ratios.  The
Company  pays a fee  equal  to 12.5 to 50 basis  points,  depending  on  certain
financial  ratios,  on the unused portion of the line of credit.  As of December
31, 2001 and September 30, 2001,  interest on the entire outstanding balance was
based on the prime rate minus 25 basis points.  The borrowing  base on this line
of credit is limited to 80% of accounts  receivable  and 50% of  inventory.  The
balance outstanding on this line of credit at December 31, 2001 was $883,487.

     On June 24, 1999 the Company obtained a $3,500,000 commercial mortgage with
a bank. The mortgage note requires 59 monthly principal payments of $19,444 plus
interest  followed  by a  final  payment  for the  unpaid  principal  amount  of
$2,352,804  due June 24, 2004.  Interest is charged at the one-month  LIBOR rate
plus 200 basis points (4.08% at December 31, 2001).

     The Company has capital lease  arrangements  to finance the  acquisition of
equipment.  Future  minimum lease  payments for the capital  leases are $736,641
with $73,242 representing  interest.  The capital lease obligations will be paid
in full by fiscal year 2004.
