(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.

        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

RESULTS  OF  OPERATIONS

THREE MONTHS ENDED  DECEMBER 31, 2000 COMPARED WITH THREE MONTHS ENDED  DECEMBER
31, 1999

     Total revenue for the three months ended December 31, 2000 increased  22.0%
to $5.4 million from $4.4 million for the three months ended  December 31, 1999.
The net increase of $1.0 million was primarily due to increased revenue from the
sale of the Culex automated blood sampling devices and related  products,  which
increased  product sales to $2.3 million for the three months ended December 31,
2000 from $1.7 million for the three months ended December 31, 1999.

     Total  cost of  revenue  for the  three  months  ended  December  31,  2000
decreased  1.1% to $3.00  million from $3.04  million for the three months ended
December  31,  1999.  Cost of services  revenue  decreased  to 72.4% of services
revenue  for the three  months  ended  December  31, 2000 from 87.2% of services
revenue  for the three  months  ended  December  31,  1999  primarily  due to an
increase in  preclinical  and  bioanalytical  service  revenue.  Cost of product
revenue  decreased  to 32.7% of  product  revenue  for the  three  months  ended
December  31,  2000 from 37.0% of product  revenue  for the three  months  ended
December 31, 1999, primarily due to a change in product mix.

     Selling  expenses for the three months  ended  December 31, 2000  decreased
3.5% to $776,000  from  $804,000 for the three  months ended  December 31, 1999.
Research and  development  expenses for the three months ended December 31, 2000
decreased  12.1% to $394,000 from  $448,000 for the three months ended  December
31, 1999, primarily as a result of an increase in grant reimbursements.  General
and  administrative  expenses  for the three  months  ended  December  31,  2000
increased  21.0% to $761,000 from  $629,000 for the three months ended  December
31,  1999,  primarily  as a result of the  increase in staff at the  preclinical
services unit.

     Other expense was $135,000 for the three months ended December 31, 2000, as
compared to other  expense of $100,000 for the three  months ended  December 31,
1999, primarily as a result of increased interest expense due to the increase in
debt.

     The Company's  effective  tax rate for the three months ended  December 31,
2000 was 45.1% as  compared to 34.5% for the three  months  ended  December  31,
1999, primarily due to nondeductible foreign losses.

LIQUIDITY AND CAPITAL RESOURCES

     At December 31, 2000, the Company had cash and cash equivalents of $391,000
compared to cash and cash  equivalents  of $477,000 at September  30, 2000.  The
decrease in cash resulted primarily from the Company's investing activities.

     The  Company's  net cash used by operating  activities  was $64,000 for the
three months ended December 31, 2000 as compared to $742,000 for the first three
months of fiscal 1999 primarily due to the reduction in accounts  payable in the
quarter ended December 31, 1999 and the effect of the consolidation of financial
results with the  acquisition  of T.P.S.,  Inc. on October 1, 1999. The negative
cash flow from  operations  during the three months ended  December 31, 2000 was
partially  the  result of a net  income of  $195,000  plus  non-cash  charges of
$575,000  offset  by  a  net  change  of  $(834,000)  in  operating  assets  and
liabilities.  The most  significant  increase  in  operating  assets  related to
accounts receivable, which increased $367,000 to $3,495,000 at December 31, 2000
primarily due to the increase in revenue.



                                     - 8 -



     Cash used by investing  activities  was $129,000 for the three months ended
December 31, 2000 as compared to $837,000  for the three  months ended  December
31, 1999 primarily due to the  acquisition of T.P.S.,  Inc. in the quarter ended
December 31, 1999.  Cash provided by financing  activities  for the three months
ended December 31, 2000 was $113,000, primarily due to the increase of debt.

     Total  expenditures by the Company for property and equipment were $129,000
and  $408,000   for  the  three  months  ended   December  31,  2000  and  1999,
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  currently has no
firm  commitments  for capital  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.

     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,
2001 and allows borrowings of up to $3,500,000.  Interest accrues monthly on the
outstanding  balance at the bank's prime rate plus 75 basis  points  (10.25 % at
December 31,  2000).  The line is  collateralized  by  inventories  and accounts
receivable and requires the Company to maintain certain financial ratios.  There
was $2,495,934 outstanding on this line of credit at December 31, 2000.

     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 (8.56% at December 31, 2000).
