(7)  NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued Statement of Financial  Accounting  Standards
("SFAS")  No.  133,   "Accounting   for  Derivative   Instruments   and  Hedging
Activities."  SFAS No. 133 is  effective  for all fiscal  quarters of all fiscal
years beginning after June 15, 2000 (October 1, 2000 for the Company).  SFAS No.
133 requires that all derivative instruments be recorded on the balance sheet at
their fair value.  Changes in the fair value of  derivatives  are recorded  each
period in current earnings or other comprehensive income, depending on whether a
derivative is designated as part of a hedge  transaction and, if it is, the type
of hedge transaction. Currently, the Company does not use derivatives.

     In June 2001, the FASB issued Statements of Financial  Accounting Standards
No. 141,  "Business  Combinations"  and No. 142,  "Goodwill and Other Intangible
Assets", effective for fiscal years beginning after December 15, 2001. 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 apply the new rules on
accounting  for  goodwill  and other  intangible  assets  beginning in the first
quarter of fiscal year 2003 (with early adoption permitted in fiscal year 2002).
Application  of the  nonamortization  provisions of the Statement is expected to
result in an  increase in net income of $77,000  ($.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 of the year of adoption of
the Statements and has not yet determined what the effect of these tests will be
on the earnings and financial position of the Company.

RESULTS OF OPERATIONS

THREE MONTHS ENDED JUNE 30, 2001 COMPARED WITH THREE MONTHS ENDED JUNE 30, 2000

     Total revenue for the three months ended June 30, 2001  increased  17.4% to
$6.4 million from $5.5 million for the three months ended June 30, 2000. The net
increase of $900,000 was primarily due to increased revenue from services, which
increased  to $3.7  million in the three  months  ended June 30,  2001 from $2.5
million for the three  months  ended June 30, 2000.  This was  primarily  due to
additional bioanalytical, preclinical and pharmaceutical contracts.

     Total  cost of  revenue  for the  three  months  ended  June  30,  2001 was
unchanged at $3.3 million when compared to the three months ended June 30, 2000.
Cost of services  revenue  decreased to 65.4% of services  revenue for the three
months  ended June 30, 2001 from 90.1% of services  revenue for the three months
ended June 30, 2000 primarily due to an increase in  bioanalytical,  preclinical
and  pharmaceutical  revenue.  Cost of  product  revenue  decreased  to 32.7% of
product  revenue for the three  months ended June 30, 2001 from 34.6% of product
revenue for the three months ended June 30, 2000,  primarily  due to a change in
product mix.

     Selling  expenses for the three months ended June 30, 2001 decreased  19.0%
to $817,000 from  $1,009,000  for the three months ended June 30, 2000 primarily
due to decreased distributors commissions. Research and development expenses for
the three months ended June 30, 2001  decreased  17.2% to $390,000 from $471,000
for the three  months  ended June 30,  2000  primarily  due to  increased  grant
reimbursements.  General and administrative  expenses for the three months ended
June 30, 2001  increased  20.3% to $925,000  from  $769,000 for the three months
ended June 30, 2000,  primarily  from increased  administrative  staffing in the
preclinical services unit.

     Other expense,  net,  decreased  42.9% to $72,000 in the three months ended
June 30,  2001,  as  compared to other  expense of $126,000 in the three  months
ended June 30, 2000,  primarily as a result of decreased interest expense due to
the decrease in the outstanding balance under the revolving line of credit.

                                       8


     The  Company's  effective tax rate for the three months ended June 30, 2001
was  42.5% as  compared  to 35.0%  for the  three  months  ended  June 30,  2000
primarily due to nondeductible foreign losses.

NINE MONTHS ENDED JUNE 30, 2001 COMPARED WITH NINE MONTHS ENDED JUNE 30, 2000

     Total  revenue for the nine months ended June 30, 2001  increased  33.5% to
$18.7  million from $14.0  million for the nine months ended June 30, 2000.  The
net  increase of $4.7  million  was  primarily  due to  increased  revenue  from
services,  which  increased  to $11.0  million in the nine months ended June 30,
2001 from $8.0  million for the nine  months  ended June 30, 2000 as a result of
the increase in bioanalytical, preclinical and pharmaceutical contracts. Product
revenue  increased  to $7.6 million for the nine months ended June 30, 2001 from
$6.1 million for the nine months ended June 30, 2000, primarily due to increased
revenue  from the sale of Culex  automated  blood  sampling  devices and related
products, animal monitoring related products and the epsilon family of products.

     Total cost of revenue  for the nine months  ended June 30,  2001  increased
7.3% to $9.7  million from $9.0 million for the nine months ended June 30, 2000.
This increase of $700,000 was primarily  due to the  additional  cost of product
revenue  due to the  increase  in  product  revenue.  Cost of  services  revenue
decreased  to 64.8% of services  revenue for the nine months ended June 30, 2001
from 86.8% of services revenue for the nine months ended June 30, 2000 primarily
due to an increase in bioanalytical,  preclinical and pharmaceutical  contracts.
Cost of  product  revenue  decreased  to 32.9% of product  revenue  for the nine
months  ended June 30,  2001 from 35.5% of product  revenue  for the nine months

     Selling  expenses for the nine months ended June 30, 2001 decreased 1.3% to
$2,505,000 from $2,539,000 for the nine months ended June 30, 2000 primarily due
to decreased distributors commissions. Research and development expenses for the
nine months ended June 30, 2001 decreased  12.1% to $1,201,000  from  $1,367,000
for the nine months ended June 30, 2000  primarily  due to the increase in grant
reimbursements.  General and  administrative  expenses for the nine months ended
June 30, 2001 increased  26.2% to $2,710,000 from $2,147,000 for the nine months
ended June 30, 2000,  primarily  from increased  administrative  staffing in the
preclinical services unit.

Other  expense,  net, was  $336,000 in the nine months  ended June 30, 2001,  as
compared to  $358,000  in the nine  months  ended June 30, 2000 as a result of a
decrease in  interest  expense due to the  decrease in the  outstanding  balance
under the revolving line of credit.

The  Company's  effective  tax rate for the nine months  ended June 30, 2001 was
42.4% as compared to 35.0% for the nine months  ended June 30,  2000,  primarily
due to nondeductible foreign losses.

LIQUIDITY AND CAPITAL RESOURCES

     At June 30,  2001,  the Company had cash and cash  equivalents  of $400,000
compared to cash and cash  equivalents  of $477,000 at September  30, 2000.  The
decrease in cash resulted primarily from the Company's financing activities.

     The  Company's  net  cash  provided  (used)  by  operating  activities  was
$2,789,000  for the nine  months  ended June 30, 2001 as compared to $ (738,000)
for the first nine months of fiscal 2000. The positive cash flow from operations
during the nine  months  ended June 30, 2001 was  partially  the result of a net
income of $1,292,000.  The most  significant  increase in operating  liabilities
related to accounts payable,  which increased $349,000 to $1,747,000 at June 30,
2001.

     Cash used by  investing  activities  was $884,000 for the nine months ended
June 30, 2001 as compared to $1,199,000 for the nine months ended June 30, 2000,
primarily due to the  acquisition of T.P.S.,  Inc. in the nine months ended June
30, 2000.  Cash used by financing  activities for the nine months ended June 30,
2001 was  $2,003,000  primarily  due to the  decrease of the  revolving  line of
credit balance.

                                       9


     Total  expenditures by the Company for property and equipment were $884,000
and  $753,000  for the nine months  ended June 30, 2001 and 2000,  respectively.
Expenditures  made in connection  with the expansion of the Company's  operating
facilities  and  purchases  of  laboratory  equipment  account  for the  largest
portions of these  expenditures.  The Company  currently has no firm commitments
for capital  expenditures.  The  Company  expects to make other  investments  to
expand its operations  through internal growth and, as attractive  opportunities
arise, through strategic acquisitions, alliances and joint ventures.

     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 working  capital 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 basis  points (6.50 % at
June  30,  2001).  The  line  is  collateralized  by  inventories  and  accounts
receivable and requires the Company to maintain certain financial ratios.  There
was $614,638  outstanding  on this line of credit at June 30, 2001. The interest
accrues monthly on the outstanding  balance at the bank's prime rate minus 25 to
plus 75 basis points or at the London Interbank Offered Rate (LIBOR) plus 200 to
300 basis points depending on certain financial ratios.

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 (5.75% at June 30, 2001).
