(1)  Basis of Presentation

    The  accompanying  unaudited  consolidated  financial  statements  have been
prepared in accordance  with generally  accepted  accounting  principles for the
interim financial information and with the instructions to Form 10-Q and Article
10 of Regulation  S-X.  Accordingly,  they do not include all of the information
and footnotes required by generally accepted accounting  principles for complete
financial statements. In the opinion of management,  all adjustments (consisting
of  only  normal  recurring   adjustments)   considered  necessary  for  a  fair
presentation  have been included.  Operating  results for the three months ended
March  31,  1997  are not  necessarily  indicative  of the  results  that may be
expected for the year ending December 31, 1997. For further  information,  refer
to the consolidated  financial  statements and footnotes thereto included in the
Form 10-K  filing  for the  fiscal  year  ended  December  31,  1996 for  Boston
Biomedica, Inc. and Subsidiaries ("the Company" or "Boston Biomedica").  Certain
prior years'  amounts in the  consolidated  financial  statements  may have been
reclassified to conform to the current year's presentation.

(3) Computation of Income (Loss) Per Share

    Net income per common  share is  computed  based upon the  weighted  average
number of common shares and as appropriate,  common equivalent shares (using the
treasury stock method)  outstanding after certain  adjustments  described below.
Common   equivalent   shares  consist  of  common  stock  options  and  warrants
outstanding.  In  accordance  with  Securities  and  Exchange  Commission  Staff
Accounting Bulletin No. 83, all common, redeemable common, and common equivalent
shares  issued  during the twelve month period prior to the proposed date of the
initial  filing  of  the  Registration  Statement  have  been  included  in  the
calculation  as if they were  outstanding  for all periods  prior to the initial
public  offering  using the treasury stock method and an offering price of $8.50
per share.  Fully diluted net income (loss) per common share is not presented as
it does not materially differ from primary earnings per share.

    In February 1997, the Financial  Accounting Standards Board issued Statement
of Financial  Accounting  Standards ("SFAS") No. 128, "Earnings per Share." SFAS
128  establishes  a different  method of computing  net income per share than is
currently  required under the provisions of Accounting  Principles Board Opinion
No. 15.  Under SFAS No. 128,  the Company will be required to present both basic
net income per share and diluted net income per share.  Basic net income  (loss)
per share for the  quarters  ended  March 31,  1997 and 1996 would have been the
same as the reported primary net income (loss) per share. The impact of SFAS 128
on the  calculation  of diluted net income per share for these quarters does not
materially  differ from basic net income (loss) per share.  The Company plans to
adopt  SFAS  128 for  periods  after  December  15,  1997  and at that  time all
historical  net income per share data  presented  will be restated to conform to
the provisions of SFAS No. 128.

Subsequent Event

    In April 1997,  the Company  exercised  its option to purchase an additional
165,000 shares of BioSeq,  Inc. stock at an aggregate cost of $750,750,  thereby
increasing its ownership of BioSeq to 19%.

ITEM2.  MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  RESULTS OF  OPERATIONS  AND
        FINANCIAL CONDITION.

THREE MONTHS ENDED MARCH 31, 1997 AND 1996

    Total revenue increased 36.5%, or $1,125,000,  to $4,209,000 for the quarter
ended March 31, 1997 from $3,084,000 in the prior year period. This increase was
the result of an increase in product sales of 17.2%, or $312,000,  to $2,127,000
from  $1,815,000 and an increase in specialty  laboratory  services of 64.1%, or
$813,000, to $2,082,000 from $1,269,000.  Product revenue increased primarily as
a result of an overall sales increase of 40.2% in Quality Control Products,  due
to continued  strong  sales of new and existing of Accurun( and panel  products.
This was partially offset by a decline of 36% in sales of Diagnostic  Components
as certain  custom  orders were  delayed.  The  increase in service  revenue was
primarily  attributable  to a 74.3%  increase in Specialty  Clinical  Laboratory
Testing revenue, particularly from Lyme Disease and the new HIV molecular tests.

    Gross profit  increased  59.7%,  or $627,000,  to $1,678,000 for the current
quarter  from  $1,051,000  in the prior year  period.  The gross  profit  margin
increased  to 39.9% for the  current  quarter  versus  34.1% in the  prior  year
period.  The gross margin improvement was entirely driven by improved margins in
services  (10.6% in 1996 to 29.1% in 1997) as the Company  continued  to benefit
from both the  addition  of  several  new tests and higher  volume in  Specialty
Clinical Laboratory Testing.

    Research and development  expenses increased 42.1%, or $70,000,  to $237,000
for the current  quarter from  $167,000 in the prior year period.  This increase
was primarily the result of additional  research  project  expenditures  for new
Quality Control  Products,  including panels and Accurun(,  as well as continued
work on additional molecular tests for our Specialty Clinical Laboratory.

    Selling and marketing expenses increased 47.8%, or $198,000, to $613,000 for
the current  quarter from  $415,000 in the prior year period.  This increase was
primarily attributable to increased personnel costs associated with the addition
of both  tele-sales  and field  staff,  as well as technical  support  staff for
Quality Control Products, particularly Accurun(, increased advertising and trade
show costs for all the  Company's  products and services,  and increased  travel
costs.

    General  and  administrative  expenses  increased  26.6%,  or  $143,000,  to
$679,000 for the current  quarter from  $536,000 in the prior year period.  This
increase was primarily a result of increased MIS and other support personnel, as
well as the increased costs incurred as a public company.

    Net  interest  income of $97,000  was  earned for the first  quarter of 1997
versus a ($94,000)  expense in the prior year period as the Company  repaid most
of its debt in the fourth  quarter of 1996 and  invested its  available  cash in
short term, investment grade securities.

    For both first quarters,  the Company provided taxes at the combined federal
and state statutory rate of 40%.

LIQUIDITY AND FINANCIAL CONDITION

    On October 31, 1996 the Company commenced trading as a result of its initial
public offering of its common stock ("IPO"),  selling  1,600,000 shares at $8.50
per share. Net proceeds raised after underwriting discounts and commissions (but
before offering costs) was $12,648,000.  On November 5, 1996, the Company repaid
substantially all of its outstanding bank debt which totaled  approximately $3.9
million.

    The Company has  financed  its  operations  to date  through  cash flow from
operations,  borrowings  from banks and sales of equity.  With the  repayment of
debt from the IPO proceeds,  the Company expects its cash flow and cash position
to meet existing operational needs. In addition, the Company has available to it
a $7.5 million  uncollateralized  revolving  line of credit with its bank should
additional needs arise.

    Net cash  provided by  operations  for the three months ended March 31, 1997
was $53,000 as compared to $789,000 in the prior year period.  This  decrease in
cash flow was primarily  attributable to increased working capital  requirements
and net  payments  of  $531,000  during the first  quarter  of 1997 of  expenses
accrued as of December 31, 1996 related to income taxes and commissions.


                                       6




    Cash used in investing  activities for the three months ended March 31, 1997
was  $1,127,000 as compared to $116,000 in the prior year period.  This increase
in investing  activities was the result of increased capital expenditures as the
Company began  construction of improvements at its manufacturing  facility,  and
financed  certain  working  capital  needs  in  connection  with  its  announced
acquisition of the assets of Source Scientific,  Inc.,  scheduled for closing in
the  second  quarter  of 1997 at an agreed  upon cost of $2.1  million  dollars,
subject to shareholder approval. In April 1997, the Company exercised its option
to purchase an additional  165,000 shares of BioSeq,  Inc. stock at an aggregate
cost of $750,750, thereby increasing its ownership of BioSeq to 19%.

    Cash provided by financing  activities  for the three months ended March 31,
1997 was  $10,000  as  compared  to  $675,000  used to repay  debt in the  prior
comparable  year period.  The net cash  provided in 1997  resulted  from $14,000
received for stock options exercises.

    The Company anticipates capital  expenditures to increase over the near term
as it expects to use  approximately  $750,000  from the  proceeds  of its IPO to
expand its manufacturing capacity in West Bridgewater over the next nine months.
The Company  believes  that  existing  cash  balances,  the  borrowing  capacity
available  under  its new  revolving  line of  credit  and cash  generated  from
operations  are  sufficient  to  fund   operations   and   anticipated   capital
expenditures  for the  foreseeable  future.  There  were no  material  financial
commitments  for capital  expenditures as of March 31, 1997, and currently there
are no material  commitments for capital or investment  expenditures  other than
the April BioSeq investment, the Source Scientific, Inc. asset acquisition,  and
the manufacturing expansion, all as previously discussed above.

RECENT ACCOUNTING PRONOUNCEMENTS

    In February 1997, the Financial  Accounting Standards Board issued Statement
of Financial  Accounting  Standards ("SFAS") No. 128, "Earnings per Share." SFAS
128  establishes  a different  method of computing  net income per share than is
currently  required under the provisions of Accounting  Principles Board Opinion
No. 15.  Under SFAS No. 128,  the Company will be required to present both basic
net income per share and diluted net income per share.  Basic net income  (loss)
per share for the  quarters  ended  March 31,  1997 and 1996 would have been the
same as the reported primary net income (loss) per share. The impact of SFAS 128
on the  calculation  of diluted net income per share for these quarters does not
materially  differ from basic net income (loss) per share.  The Company plans to
adopt  SFAS  128 for  periods  after  December  15,  1997  and at that  time all
historical  net income per share data  presented  will be restated to conform to
the provisions of SFAS No. 128.

FORWARD-LOOKING STATEMENTS

    This  Quarterly  Report on Form  10-Q  contains  forward-looking  statements
concerning the Company's  financial  performance  and business  operations.  The
Company  wishes to caution  readers of this  Quarterly  Report on Form 10-Q that
actual   results   might  differ   materially   from  those   projected  in  any
forward-looking statements.

    Factors  which might cause actual  results to differ  materially  from those
projected  in  the  forward-looking  statements  contained  herein  include  the
following:  inability  of the Company to develop the end user market for quality
control  products;  inability of the Company to integrate the business of Source
Scientific,  Inc. into the Company's business;  inability of the Company to grow
the sales of Source  Scientific,  Inc. to the extent  anticipated;  inability of
Source  Scientific,  Inc.  to repay the  $750,000  loan made by the  Company;  a
material  adverse  change in the business,  financial  condition or prospects of
BioSeq, Inc., an early stage biotechnology company in which the Company has made
a significant investment;  inability of the Company to obtain an adequate supply
of the unique and rare  specimens of plasma and serum  necessary  for certain of
its products;  significant reductions in purchases by any of the Company's major
customers; and the potential insufficiency of Company resources, including human
resources, plant and equipment and management systems, to accommodate any future
growth.  Certain of these and other factors which might cause actual  results to
differ  materially  from  those  projected  are more  fully set forth  under the
caption "Risk Factors" in the Company's  Registration Statement on Form S-1 (SEC
File No. 333-10759).
