     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

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 and
the six month period ended March 31, 2002 are not necessarily  indicative of the
results for the year ending September 30, 2002.

(4) DEBT

     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 March 31, 2002) 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 0.125 to 0.5 basis  points,  depending  on  certain
financial  ratios,  on the unused portion of the line of credit. As of March 31,
2002 and September 30, 2001 interest on the entire outstanding balance was based
on the prime rate minus 25 basis points. The balance outstanding on this line of
credit at March 31, 2002 was  $2,648,475.  The Company has renewed the revolving
line of credit,  which now expires April 1, 2004.  The new interest rate will be
at the bank's prime rate minus 25 basis points.

support on a contract basis directly to pharmaceutical  companies. The Company's
products unit provides liquid chromatography,  electrochemical and physiological
monitoring  products  to  pharmaceutical  companies,  universities,   government
research  centers  and medical  research  institutions.  The  Company  evaluates
performance and allocates resources based on these segments.

(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  indefinite  lived
intangible  assets are no longer be  amortized,  but are  reviewed  annually for
impairment.  Separable  intangible  assets  that  are  not  deemed  to  have  an
indefinite  life will  continue to be  amortized  over their useful  lives.  The
amortization  provisions of SFAS No. 142 apply to goodwill and intangible assets
acquired  after June 30, 2001.  With respect to goodwill and  intangible  assets
acquired prior to July 1, 2001, the Company will apply the new accounting  rules
beginning October 1, 2002. Application of the nonamortization  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.

RESULTS OF OPERATIONS

THREE  MONTHS  ENDED MARCH 31, 2002  COMPARED  WITH THREE MONTHS ENDED MARCH 31,
2001

     Total revenue for the three months ended March 31, 2002  increased  7.9% to
$7.4 million  from $6.8  million for the three months ended March 31, 2001.  The
net increase of $600,000 was primarily due to product revenue which increased to
$3.1 million for the three months ended March 31, 2002 from $2.6 million for the
three months ended March 31, 2001.  This was primarily due to increased  revenue
from  the  sale of the  Culex  automated  blood  sampling  devices  and  related
products.

     Total cost of revenue for the three months  ended March 31, 2002  increased
25.8% to $4.2  million  from $3.4  million for the three  months ended March 31,
2001. This increase of $800,000 was primarily due to the cost of revenue related
to the  additional  Culex and  related  product  sold.  Cost of service  revenue
increased  to 65.8% as a  percentage  of services  revenue for the three  months
ended March 31, 2002 from 58.9% of service  revenue for the three  months  ended
March 31, 2001  primarily due to an increase in staffing and increases in wages.
Cost of product  revenue  increased to 46.0% as a percentage of product  revenue
for the three months ended March 31, 2002 from 33.3% of product  revenue for the
three months ended March 31, 2001, primarily due to a change in product mix.

     Selling  expenses for the three months ended March 31, 2002  decreased 4.0%
to $876,000  from  $912,000 for the three months ended March 31, 2001  primarily
due to the decrease in foreign  jobbers  commission.  Research  and  development
expenses for the three months ended March 31, 2002  decreased  6.7% to $ 389,000
from $417,000 for the three months ended March 31, 2001 primarily as a result of
an increase in grant reimbursements. General and administrative expenses for the
three months ended March 31, 2002 increased 6.2% to $1,087,000  from  $1,024,000
for the three  months ended March 31, 2001,  primarily  from the  organizational
restructuring of our preclinical operation.

     Other  expense was $49,000 in the three  months  ended March 31,  2002,  as
compared to other  expense of $129,000 in the three months ended March 31, 2001,
primarily as a result of decreased  interest  expense due to the decrease in the
interest rates.



                                     - 8 -


     The Company's  effective tax rate for the three months ended March 31, 2002
was 30.4% as  compared  to 41.3%  for the three  months  ended  March 31,  2001,
primarily  due to the  utilization  of the tax benefit of foreign net  operating
losses.


SIX MONTHS ENDED MARCH 31, 2002 COMPARED WITH SIX MONTHS ENDED MARCH 31, 2001

     Total  revenue for the six months  ended March 31, 2002  increased  9.3% to
$13.4  million from $12.3  million for the six months ended March 31, 2001.  The
net  increase of $900,000 was  primarily  due to revenue  from  products,  which
increased  to $5.6  million  for the six months  ended  March 31, 2002 from $4.9
million  for the six months  ended March 31,  2001.  This was  primarily  due to
increase revenue from the sale of the Culex automated blood sampling devices and
related  products.  Service revenue  increased to $7.8 million in the six months
ended March 31, 2002 from $7.4  million for the six months ended March 31, 2001.
This was primarily due to additional contracts in pharmaceutical and preclinical
services.

     Total cost of revenue for the six months  ended  March 31,  2002  increased
20.9% to $7.7 million from $6.4 million for the six months ended March 31, 2001.
This  increase of $1.3  million  was  primarily  due to the  increase in product
revenue.  Cost of service revenue  increased to 69.3% as a percentage of service
revenue for the six months  ended  March 31, 2002 from 64.6% of service  revenue
for the six months ended March 31, 2001 primarily due to an increase in staffing
costs.  Cost of product  revenue  increased to 41.0% as a percentage  of product
revenue for the six months  ended  March 31, 2002 from 33.0% of product  revenue
for the six months ended March 31, 2001,  primarily due to the change in product
mix.

     Selling  expenses for the six months ended March 31, 2002 decreased 2.0% to
$1,654,000 from $1,688,000 for the six months ended March 31, 2001 primarily due
to the decrease in foreign jobbers commission. Research and development expenses
for the six  months  ended  March 31,  2002  decreased  12.2% to  $712,000  from
$811,000 for the six months ended March 31, 2001  primarily  due to the increase
in grant reimbursements.  General and administrative expenses for the six months
ended March 31, 2002 increased  17.9% to $2,105,000  from $1,785,000 for the six
months ended March 31, 2001, primarily from the organizational  restructuring of
our preclinical operation.

     Other  expense  was  $74,000 in the six months  ended  March 31,  2002,  as
compared to  $264,000  in the six months  ended March 31, 2001 as a result of an
decrease in interest  expense due to the  decrease in the  interest  rate of the
Company's line of credit.

     The  Company's  effective  tax rate for the six months ended March 31, 2002
was  33.8% as  compared  to 42.3%  for the six  months  ended  March  31,  2001,
primarily  due to the  utilization  of the tax benefit of foreign net  operating
losses.


LIQUIDITY AND CAPITAL RESOURCES

     At March 31, 2002,  the Company had cash and cash  equivalents  of $381,000
compared to cash and cash equivalents of $374,000 at September 30, 2001.

     The  Company's  net  cash  provided  (used)  by  operating  activities  was
$(719,000)  for the six months  ended March 31, 2002 as compared to $937,000 for
the first six months of fiscal 2001.  The  decreased  cash flow from  operations
during the six months  ended  March 31, 2002 was  primarily  related to accounts
receivable,  which  increased  $1,052,000  to  $5,318,000  and the  decrease  in
accounts payable, which decreased $972,000.



                                     - 9 -


     Cash used by investing  activities  was $1,477,000 for the six months ended
March 31, 2002 as compared to $618,000  for the six months ended March 31, 2001,
primarily due to the  construction at our  preclinical  site and the purchase of
additional  lab  equipment.  Cash provided by financing  activities  for the six
months ended March 31, 2002 was  $2,180,000  as compared to $491,000 for the six
months ended March 31, 2001,  primarily due to the increased  utilization of the
revolving line of credit.

     Total   expenditures  by  the  Company  for  property  and  equipment  were
$1,227,000  and  $618,000  for the six  months  ended  March 31,  2002 and 2001,
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.  During the quarter ended March
31, 2002,  the Company signed a letter of intent to purchase a building near its
headquarters in West Lafayette,  Indiana. The Company made a $250,000 deposit on
the purchase of this  building.  The Company  plans to obtain a mortgage  with a
commercial lender to finance this purchase.

     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 March 31, 2002) 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 0.125 to 0.5 basis  points,  depending  on  certain
financial  ratios,  on the unused portion of the line of credit. As of March 31,
2002 and September 30, 2001 interest on the entire outstanding balance was based
on the prime rate minus 25 basis points. The balance outstanding on this line of
credit at March 31, 2002 was  $2,648,475.  The Company has renewed the revolving
line of credit,  which now expires April 1, 2004.  The new interest rate will be
at the bank's prime rate minus 25 basis points.

     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 (3.85% at March 31, 2002).

The Company has capital lease arrangements to finance the acquisition of
equipment. Future minimum lease payments for the capital leases are $582,894
with $47,292 representing interest. The capital lease obligations will be paid
in full by fiscal year 2004.
