                   Notes to Consolidated Financial Statements
                                   (Unaudited)




(1)       Basis of Presentation-

          The consolidated  financial  statements  included herein have not been
          examined  by   independent   public   accountants,   but  include  all
          adjustments (consisting of normal recurring entries) which are, in the
          opinion  of  management,  necessary  for a  fair  presentation  of the
          results for such periods.

          Certain  information  and footnote  disclosures  normally  included in
          financial  statements  prepared in accordance with generally  accepted
          accounting  principles have been omitted  pursuant to the requirements
          of the  Securities  and  Exchange  Commission,  although  the  Company
          believes that the disclosures  included in these financial  statements
          are adequate to make the information not misleading.

          It is suggested that these consolidated  financial  statements be read
          in conjunction  with the consolidated  financial  statements and notes
          thereto included in the Company's latest annual report on Form 10-K.

          The results of operations for the interim  periods are not necessarily
          indicative of the results to be expected for the year.


(2)       Inventories-

          Inventories are comprised of the following:



                                              March 31,         September 30,

(3)       Income Taxes-

          The  provisions  for  income  taxes  were  computed  at the  estimated
          annualized  effective tax rates  utilizing  current tax law in effect,
          after giving effect to research and experimentation credits.


(4)       Earnings Per Common Share-

          Net  earnings  per share has been  computed  based  upon the  weighted
          average number of shares outstanding  during the periods.  No material
          dilution results from outstanding stock options, the only common stock
          equivalents,  nor from the assumed  conversion  of the 7%  Convertible
          Subordinated  Debentures issued September 27, 1996, due in 2006. These
          debentures  assuming their conversion,  net of the pro forma after tax
          interest  expense,   are  anti-dilutive.   All  share  and  per  share
          information have been adjusted to reflect the conversion of the 7 1/4%
          Convertible Subordinated Debentures due in 2001, called for redemption
          on October 10, 1995 into  common  stock,  as well as the 3 for 2 stock
          split in October 1995.

          In February  1997,  the Financial  Accounting  Standards  Board issued
          Statement No. 128 "Earnings Per Share" (Statement 128). This statement
          requires the  presentation  of basic EPS and diluted EPS. Basic EPS is
          computed by dividing  income  available to common  stockholders by the
          weighted average number of common shares  outstanding.  Diluted EPS is
          computed by adding to the  weighted  average  number of common  shares
          outstanding the dilutive effect of additional common shares that would
          have been outstanding if the dilutive potential common shares had been
          issued.  Using the methods prescribed in Statement 128, proforma basic
          and diluted earnings per share would be as follows:

                                              1997                     1996

(5)       Translation of Foreign Currency-

          Assets and  liabilities of foreign  operations  are  translated  using
          quarter end exchange  rates,  and revenues and expenses are translated
          using exchange rates  prevailing  during the year with gains or losses
          resulting  from  translation  included  in  a  separate  component  of
          shareholders'  equity. Gains and losses resulting from transactions in
          foreign currencies were immaterial.

(6)       Reclassifications-

          Certain reclassifications have been made to the accompanying financial
          statements to conform to the March 31, 1997 presentation.


                                  Page 8 of 14



(7)       Recently Issued Accounting Standards

          In March 1995, the Financial  Accounting Standards Board (FASB) issued
          Statement No. 121 (Statement 121) on "Accounting for the Impairment of
          Long-lived  Assets  and for  Long-lived  Assets  to be  Disposed  Of."
          Statement 121 is required to be applied prospectively for assets to be
          held and used. Statement 121 also establishes accounting standards for
          long-lived assets that are to be disposed.  The initial application of
          Statement  121 to assets held for  disposal is required to be reported
          as the  cumulative  effect of a change in  accounting  principle.  The
          Company  is  required  to adopt  Statement  121 in 1997 and,  based on
          current  circumstances,  the  effect of the  adoption  will not have a
          material effect on its financial position or results of operations.

          In October  1995,  the FASB issued  Statement of Financial  Accounting
          Standards  No.  123  (Statement  123)   "Accounting  for  Stock  Based
          Compensation"   establishing   financial   accounting   and  reporting
          standards for stock-based employee  compensation plans.  Statement 123
          encourages  the  use  of  the  fair  value  based  method  to  measure
          compensation  cost  for  stock-based   employee   compensation  plans;
          however,  it also continues to allow the intrinsic  value based method
          of  accounting as prescribed by APB Opinion No. 25, which is currently
          used by the Company.  If the intrinsic value based method continues to
          be used,  Statement 123 requires pro forma  disclosures  of net income
          and  earnings  per  share,  as if  the  fair  value  based  method  of
          accounting had been applied. The fair value based method requires that
          compensation  cost be  measured at the grant date based upon the value
          of the award and recognized over the service period, which is normally
          the vesting period.  The Company adopted  Statement 123 in fiscal 1997
          and will make the required footnote disclosures only.  Therefore,  the
          adoption  of this  Statement  will not have a  material  effect on the
          Company's financial position or results of operations.

Item 2.   Management's Discussion and Analysis Of Financial Condition
          and Results of Operations

Results of Operations

Consolidated  net sales  increased  $1,082,000,  or 15%, to  $8,337,000  for the
second fiscal quarter and increased  $3,122,000,  or 24%, to $15,899,000 for the
six months ended March 31, 1997. These increases were primarily from strong unit
volume  growth in the Premier and  ImmunoCard  lines plus growth in OEM sales in
the  U.S.  and  the  Inova  line  of  products  sold  in  Italy.  The  Para-Pak,
mononucleosis  and  FiltraCheck  product  lines were down in the second  quarter
partially offsetting the above gains. The increase in the Premier and ImmunoCard
formats  was  attributable  to  those  products  use  for  identification  of C.
difficile, H. pylori, EHEC and Mycoplasma.  The Cambridge product line, acquired
in June 1996,  contributed  over  $800,000  of sales in the second  quarter,  or
approximately  74% of the total growth over the prior year fiscal  quarter.  The
Inova line of autoimmune products in Italy increased 25% for the quarter and 84%
for the six months period with year-to-date sales of $320,000.

The  increase  in  consolidated  net sales for the  second  fiscal  quarter  was
comprised of volume of $1,544,000,  or 21%, offset by lower pricing of $399,000,
or 5%, and currency of $63,000, or 1%.  Approximately  one-fourth of the pricing
variance stems from European  operations,  similar in dollar amount to the first
fiscal  quarter,   reflecting  the  increasing  pressure  on  health  care  cost
containment in the international  markets.  The remainder of the pricing change,
about $300,000,  or 5%, relates largely to the relatively new exclusive national
contracts  established  in the U.S.  with large  hospital  chains and  reference
laboratories  and was more than  offset by unit volume  increases  which were up
about 26% in the U.S.



                                  Page 9 of 14





Gross  profit  increased  9% for the  quarter and 18% for the  six-month  period
compared to sales  increases  of 15% and 24%  respectively.  As a result,  gross
profit  declined  as a  percentage  of sales to 65.6%  compared to 69.0% for the
quarter;  to 64.9% from 68.7% for the six  months.  The  reduction  in the gross
profit rate is largely  related to the higher costs  associated with the enteric
product line acquisition from Cambridge in June 1996. The acquisition  included,
in  addition  to the  amortization  of  certain  acquisition  costs,  a one-year
inventory purchase agreement at a negotiated cost expected to be higher than the
Company's  cost of  manufacturing  when  the  purchased  product  line is  fully
integrated into the Company's manufacturing  facilities in Cincinnati during the
third fiscal quarter of 1997. In addition,  higher scrap and  replacement  costs
and higher  depreciation  and insurance costs related to expanded  manufacturing
facilities were contributing factors to a lesser extent.

Total  operating  expenses  increased  $611,000,  or 22%, for the second  fiscal
quarter and $1,133,000 or 21%, for the six months ended March 31, 1997, compared
to the prior  year.  Total  operating  expenses  were 40.7% of net sales for the
quarter,  up 2.3  percentage  points from the prior year,  and were 41.8% of net
sales for the six months, down 1.3 percentage points.

Research and development  expenses for the second fiscal quarter were up 11% and
up 14% for the six  months.  These  increases  are  attributable  to  laboratory
supplies,   consulting  and  other   professional   fees  associated  with  EHEC
development for use in food,  development of novel detection  assays and testing
devices and expenses,  namely international patent filings,  associated with the
transition of Cytoclone from Cambridge.

Selling and marketing expenses increased 24% for the quarter and 28% for the six
months compared to the comparable prior year periods, primarily from U. S. sales
personnel added  during fiscal 1996 to provide improved  geographic coverage and
penetration of  national accounts,  higher  national sales meeting  expenses and
amortization  of  certain  Cambridge  acquisition  costs.  European  selling and
marketing  expenses were  down  approximately 10% for  the periods excluding the
effect of currency.

General and administrative  expenses increased 22% for the second fiscal quarter
and 13% for the six months.  These increases are  principally  related to higher
personnel  cost in the  U.S.,  amortization  of  expenses  associated  with  the
Cambridge  acquisition,  one-time  expenses incurred this quarter for Meridian's
twentieth   anniversary  and  outside  professional  fees  for  several  special
projects. European expenses were relatively flat.

Operating  income  as a result  of the  above  decreased  $150,000,  or 7%,  and
declined  about six  percentage  points as a percentage  of sales for the second
fiscal quarter. For the six months, operating income increased $406,000, or 12%,
but declined two points as a percentage of sales.

Other expense increased by $228,000 and $431,000  respectively for the three and
six months  periods ended March 31, 1997 which is more than accounted for by the
interest expense associated with the 7% Convertible  Subordinated Debentures due
2006.  Increases in interest  income  reflect the higher amount of invested cash
(from the debentures) during the periods.  Gains/losses in foreign exchange were
not material during the periods.  The cumulative  foreign  currency  translation
adjustment changed by $267,000 during the quarter as a result of the U.S. dollar
significantly strengthening against the lira.

The  Company's  effective  tax  rate  was  essentially  flat at 41% for both the
quarter and six months periods. Net earnings decreased 16% for the second fiscal
quarter to $1,132,000  from  $1,355,000  and was  relatively  flat at $1,974,000
compared to $1,984,000 for the six months ended March 31, 1997,  compared to the
prior year.  The  corresponding  primary  earnings per share for the  comparable
periods were $0.08 and $0.10 for the quarters  respectively,  and $0.14 for both
six months periods.

Liquidity and Capital Resources

Net cash flow provided by  operations  was  $3,032,000  for the six month period
ended March 31, 1997, about equal to last year.  However,  accounts payable were
reduced during the quarter by approximately $1,700,000, in part from payment for
inventories acquired from Cambridge.

Net cash provided by investing  activities  increased  $8,249,000 as a result of
the sale of short term  investments  with maturities  greater than 90 days which
have been  reinvested into maturities of less than 90 days and reflected in Cash
and Cash  Equivalents  of  $14,662,000.  Net cash used for financing  activities
increased  $354,000,  or 28%,  the major items being  higher  dividend  payments
including  the year-end  special cash dividend of $0.025 per share plus expenses
associated with the issuance of the 7% debentures due in 2006.

Net cash flow from  operations  is expected to continue to fund working  capital
requirements.  Currently,  the Company has an unused  $10,000,000 line of credit
with a commercial bank and cash and short-term investments of $20,460,000.
