                    IDEXX LABORATORIES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)



1.   BASIS OF PRESENTATION
     The unaudited financial statements included herein have been prepared by
     IDEXX Laboratories, Inc. and subsidiaries (the "Company") pursuant to the
     rules and regulations of the Securities and Exchange Commission and
     include, in the opinion of management, all adjustments which the Company
     considers necessary for a fair presentation of such information. The
     December 31, 1996 Balance Sheet was derived from the audited Consolidated
     Balance Sheets contained in the Company's latest stockholders' annual
     report. Certain information and footnote disclosures normally included in
     financial statements prepared in accordance with generally accepted
     accounting principles have been condensed or omitted pursuant to such rules
     and regulations. These statements should be read in conjunction with the
     Company's audited consolidated financial statements and notes thereto which
     are contained in the Company's latest stockholders' annual report. The
     results for the interim periods presented are not necessarily indicative of
     results to be expected for the full fiscal year.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     The accompanying consolidated financial statements reflect the application
     of certain accounting policies described in this and other notes to the
     consolidated financial statements.

     a.   Principles of Consolidation: The accompanying consolidated financial
          statements include the accounts of the Company and its wholly-owned
          subsidiaries. All material intercompany transactions and balances have
          been eliminated in consolidation.

     b.   Certain reclassifications have been made in the 1996 consolidated
          financial statements to conform with the current years presentation.

     c.   The Company adopted Statement of Financial Accounting Standards No.
          115 "Accounting for Certain Investments in Debt and Equity Securities"
          (SFAS No. 115) effective January 1, 1994. Accordingly, the Company's
          cash equivalent and short-term investments are classified as
          held-to-maturity and are recorded at amortized cost which approximates
          market value.

          Cash Equivalents and Short-term Investments: Cash equivalents are
          short-term, highly liquid investments with original maturities of less
          than three months. Short-term investments are investment securities
          with original maturities of greater than three months but less than
          one year and consist of the following (in thousands):

3.   NET INCOME PER SHARE
     Net income per common and common equivalent share is based on the weighted
     average number of common and common equivalent shares outstanding during
     each period, computed in accordance with the treasury stock method. Fully
     diluted net income per common and common equivalent share has not been
     presented as it is not significantly different.

     In February 1997 the Financial Accounting Standards Board issued Statement
     of Financial Accounting Standards No. 128 "Earnings Per Share" (SFAS No.
     128). SFAS No. 128 must be adopted as of December 31, 1997 and all prior
     earnings per share amounts must be retroactively restated.

     In accordance with Staff Accounting Bulletin No. 74, the Company is
     disclosing the effect this statement would have on the three and six month
     periods ended June 30, 1997 and 1996 on a pro forma basis. The following
     table summarizes the pro forma earnings per share amounts under SFAS No.
     128 (in thousands, except per share amounts):

     Basic earnings per common share is computed by dividing net income by the
     weighted average number of shares of common stock outstanding during the
     quarter. The computation of diluted earnings per common share is similar to
     the computation of basic earnings per common share except that the
     denominator is increased for the assumed exercise of dilutive options using
     the treasury stock method. Shares outstanding for purposes of calculating
     diluted earnings (loss) per share for the six months ended June 30, 1997
     is derived from the arithmetic average of the weighted average shares
     outstanding for (i) the three months ended March 31, 1997 plus options
     issued to employees and (ii) the three months ended June 30, 1997, because
     the Company incurred a loss for the six months ended June 30, 1997.


4.   COMMITMENTS AND CONTINGENCIES

     From time to time the Company has received notices alleging that the
     Company's products infringe third-party proprietary rights. In particular,
     the Company has received notices claiming that certain of the Company's
     immunoassay products infringe third-party patents. Except as noted below
     with respect to the patent infringement suit brought by The Jewish Hospital
     of St. Louis, no litigation has been brought against the Company with
     respect to such claims. Patent litigation frequently is complex and
     expensive, and the outcome of patent litigation can be difficult to
     predict. There can be no assurance that the Company will prevail in any
     infringement proceedings that have been or may be commenced against the
     Company. A significant portion of the Company's revenue during the three
     month period ended June 30, 1996 was attributable to products incorporating
     certain immunoassay technologies and to products relating to the diagnosis
     of canine heartworm infection which are the subject of the Jewish Hospital
     suit. If the Company were to be precluded from selling such products or
     required to pay damages or make additional royalty or other payments with
     respect to such sales, the Company's business and results of operations
     could be materially and adversely affected.

     On February 4, 1993, the Company acquired Environetics, Inc.
     ("Environetics"), which brought a patent infringement suit with Stephen
     Edberg, Ph.D. against Millipore Corporation ("Millipore") in the U.S.
     District Court for the District of Connecticut on September 30, 1992 (the
     "Millipore I suit"). The complaint in the Millipore I suit was subsequently
     amended to add as additional plaintiffs Access Medical Systems, Inc., a
     subsidiary of the Company ("Access"), and Stephen C. Wardlaw, M.D. The
     primary 


                                     Page 8
   9

     relief sought by the plaintiffs is an injunction against Millipore which
     would prevent Millipore from selling a competitive product that the
     plaintiffs believe infringes U.S. Patent No. 4,925,789 (the "'789 Patent")
     covering the Company's Colilert(R) product, under which Access and
     Environetics have an exclusive license from Drs. Edberg and Wardlaw.
     Millipore has filed a counterclaim alleging that the '789 Patent is invalid
     or not infringed.

     In addition, on July 26, 1995, the Company, Environetics, Access and Drs.
     Edberg and Wardlaw brought a second patent infringement suit against
     Millipore in the U.S. District Court for the District of Connecticut (the
     "Millipore II suit"). The principal relief sought by the plaintiffs in the
     Millipore II suit is an injunction against Millipore which would prevent
     Millipore from selling a product which the plaintiffs believe infringes
     U.S. Patent No. 5,429,933 (the " '933 Patent"), which also covers the
     Colilert product. The '933 Patent, which is related to the '789 Patent, was
     issued in July 1995 to Dr. Edberg. Access and Environetics have an
     exclusive license under the '933 Patent from Drs. Edberg and Wardlaw.
     Millipore has filed a counterclaim alleging that the '933 Patent is invalid
     or not infringed.

     If the plaintiffs do not prevail in the Millipore I and Millipore II       
     suits, the Company anticipates that the Colilert product would encounter
     increased competition, which could adversely affect sales of the Colilert
     product.

     On February 24, 1995, CDC Technologies, Inc. ("CDC Technologies") filed
     suit against the Company in the U.S. District Court for the District of
     Connecticut. In its complaint, CDC Technologies alleges that the Company's
     conduct in, and its relationships with its distributors in connection with,
     the distribution of the Company's hematology products (i) violate federal
     and state antitrust statutes, (ii) violate Connecticut statutes regarding
     unfair trade practices, and (iii) constitute a civil conspiracy and
     interfere with CDC Technologies' business relations. The relief sought by
     CDC Technologies includes treble damages for antitrust violations as well
     as compensatory and punitive damages, and an injunction to prevent the
     Company from interfering with CDC Technologies' relations with
     distributors. The Company has filed an answer denying the allegations in
     CDC's complaint. The Company is unable to assess the likelihood of an      
     adverse result or estimate the amount of any damages which the Company may
     be required to pay. Any adverse outcome resulting in the payment of
     damages would adversely affect the Company's results of operations.

     On May 26, 1995, The Jewish Hospital of St. Louis (the "Hospital") brought
     a suit against the Company which is currently pending in the U.S. District
     Court for the District of Maine for infringement of U.S. Patent No.
     4,839,275 issued June 13, 1989 (the "'275 Patent"). The '275 Patent, which
     is owned by the Hospital, claims certain methods and compositions for the
     diagnosis of canine heartworm infection. The primary relief sought by the
     Hospital is an injunction against the Company which would prevent the
     Company from selling canine heartworm diagnostic products which infringe
     the '275 Patent, as well as treble damages for past infringement. In June
     1997, the court ruled, in response to a summary judgment motion by the
     Jewish Hospital, that five heartworm diagnostic kits formerly sold by
     the Company literally infringe two claims of the '275 Patent. While the
     Company believes that it has meritorious defenses in this matter, the
     Company is unable to assess the likelihood of an adverse result or
     estimate the amount of any damages which the Company may be required to
     pay. If the Company is precluded from selling canine heartworm diagnostic
     products or required to pay damages or make additional royalty or other
     payments with respect to such sales, the Company's business and results of
     operations could be materially and adversely affected.

     On September 18, 1995, Purisys Inc. ("Purisys"), a producer of home
     pollution test kits, and certain of its employees filed suit against the
     Company in the Supreme Court of the state of New York. In their complaint,
     the plaintiffs allege that the Company has breached promises and made
     negligent misrepresentations, and has breached fiduciary and other duties.
     The plaintiffs are seeking damages in excess of $50,000,000. The Company
     purchased a 15% equity interest in Purisys in August 1994 for $616,000, and
     the Company subsequently advanced additional amounts to Purisys to purchase
     certain international distribution rights. In March 1995, the Company
     ceased advancing funds to Purisys, which filed for protection under the    
     Bankruptcy Code in July 1995. In May 1996, the court granted the Company's
     motion to dismiss the plaintiffs' suit, and the plaintiffs' appeals of
     that dismissal were dismissed by the court in July 1997. While the Company
     believes it has meritorious defenses, the Company is unable to assess 

                                     Page 9
   10

     the likelihood of an adverse result or estimate the amount of any damages
     which the Company may be required to pay. Any adverse outcome resulting in
     the payment of damages would adversely affect the Company's results of
     operations.

5.   ACQUISITIONS

     1996 ACQUISITIONS
     -----------------
 
     The Company's consolidated results of operations include the results of
     operations of four veterinary reference laboratory businesses and two
     manufacturers of detection and diagnostic tests acquired in 1996. These
     businesses were acquired by the Company for aggregate purchase prices
     equaling approximately $19.7 million in cash, the issuance of a note
     payable for $3.0 million, the assumption of certain liabilities and the
     issuance of the Company's Common Stock and options exercisable for Common
     Stock totaling approximately $20 million.

     In connection with the acquisition of the veterinary reference laboratory
     businesses and one of the manufacturing businesses, the Company entered
     into non-compete agreements for periods of up to five years with certain
     of the entities, stockholders or former stockholders, and may become
     obligated to pay additional amounts to management of these companies based
     on achieving certain operating results. The Company has accounted for these
     acquisitions under the purchase method of accounting. The results of
     operations of each of these businesses has been included in the Company's
     consolidated results of operations since their respective dates of
     acquisition. The Company has not presented pro forma financial information
     relating to any of these acquisitions because of immateriality. These
     acquisitions are as follows:

          o    On March 29, 1996, the Company acquired all of the capital stock
               of VetLab, Inc. ("VetLab"), which operated two veterinary
               reference laboratories in Texas.

          o    On April 2, 1996, the Company, through its wholly-owned
               subsidiary, IDEXX Laboratories, Limited, acquired substantially
               all of the assets and assumed certain of the liabilities of
               Grange Laboratories Ltd. ("Grange Laboratories"). Grange
               Laboratories' business, which includes veterinary reference
               laboratories in the United Kingdom, is now operated as a division
               of IDEXX Laboratories, Limited.

          o    On May 15, 1996, the Company acquired all of the capital stock of
               Veterinary Services, Inc. ("VSI"), which operated veterinary
               reference laboratories in Colorado, Illinois and Oklahoma.

          o    On July 12, 1996, the Company acquired substantially all of the
               assets and assumed certain of the liabilities of Consolidated
               Veterinary Diagnostics, Inc. ("CVD"). As a result of the CVD
               acquisition, the Company is operating CVD's veterinary reference
               laboratories in Northern California, Oregon and Nevada.

          o    On July 18, 1996, the Company acquired all of the capital stock
               of Ubitech Aktiebolag, located in Uppsala, Sweden, which
               manufactures and distributes diagnostic test kits for the
               livestock industry.

     The VetLab, VSI and CVD businesses are operated by IDEXX Veterinary 
     Services, Inc., a wholly-owned subsidiary of the Company.

     In connection with the Company's acquisition by merger of Idetek, Inc.
     ("Idetek") on August 29, 1996, the Company issued 436,804 shares of its
     Common Stock, of which approximately 10% are held in escrow, in exchange
     for all of the outstanding capital stock of Idetek. In addition,
     outstanding options to purchase shares of Idetek capital stock became
     options to acquire 110,191 shares of the Company's Common Stock at prices
     ranging from $3.13 to $78.14. The value of the shares of the Company's
     Common Stock issued or reserved for issuance as a result of the merger
     totaled approximately $20 million. Idetek, located in Sunnyvale,
     California, manufactured and distributed detection tests for the food,
     agricultural 

                                    Page 10
   11

     and environmental industries. The Company has accounted for this
     acquisition by merger as a "pooling-of-interests". The results of
     operations of Idetek have been included in the Company's consolidated
     results of operations since the date of the merger. The Company has not
     restated its financial statements because of immateriality.

     1997 ACQUISITIONS
     -----------------

     The Company's consolidated results of operations include the results of
     operations of a manufacturing company and a software company acquired in
     1997. These businesses were acquired for aggregate purchase prices equaling
     approximately $9.9 million in cash, the issuance of a note payable for $1.5
     million and the assumption of certain liabilities.

     In connection with the acquisition of the businesses described above, the
     Company entered into non-compete agreements for a period of up to three
     years with certain of the former stockholders, and may become obligated to
     pay additional amounts to management of these companies based on achieving
     certain operating results. The Company has accounted for these acquisitions
     under the purchase method of accounting. The results of operations of each
     of these businesses has been included in the Company's consolidated results
     of operations since the respective dates of acquisition. The Company has 
     not presented pro forma financial information relating to either of these 
     acquisitions because of immateriality. These acquisitions are as follows:

          o    On January 30, 1997, the Company acquired all of the capital
               stock of Acumedia Manufacturers, Inc., located in Baltimore,
               Maryland, which specializes in the manufacture of dehydrated
               culture media.

          o    On March 13, 1997, the Company acquired all of the capital stock
               of National Information Systems Corporation, located in Eau
               Claire, Wisconsin, which supplies practice management computer
               systems to veterinarians under the trade name Advanced Veterinary
               Systems.

6.   SUBSEQUENT EVENTS

     Subsequent to June 30, 1997, the Company acquired the following businesses 
     for approximately $13.5 million in cash and the assumption of certain
     liabilities. The Company has accounted for these acquisitions under the 
     purchase method of accounting. These acquisitions are as follows:

          o    On July 1, 1997, the Company acquired certain assets and other
               rights of Wintek Bio-Science Inc., located in Taipei, Taiwan,
               which distributes diagnostic products to veterinarians in
               Taiwan. 

          o    On July 18, 1997, the Company acquired all of the capital stock
               of Professionals' Software, Inc., located in Effingham,
               Illinois, which supplies practice management computer systems to
               veterinarians. 

     The Company has not presented pro forma financial information relating to
     either of these acquisitions because of immateriality.

     Item 2.

                    IDEXX LABORATORIES, INC. AND SUBSIDIARIES
           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Total revenue for the second quarter of 1997 decreased 11% to $58.9 million from
$65.9 million for the second quarter of 1996. Total revenue for the six months
ended June 30, 1997 decreased 3% to $119.4 million from $123.3 million for the
first six months of 1996.

The decrease in total revenue for the quarter ended June 30, 1997 compared to
the same period in 1996 was principally attributable to decreased sales of
veterinary test kits, instruments, and consumables, offset by increased sales
of veterinary laboratory services which resulted from acquisitions of
veterinary reference laboratories in the second and third quarters of 1996,
food and environmental products, and veterinary practice management software
and equipment, which resulted from the acquisition of National Information
Systems Corp. in the first quarter of 1997. The decrease in revenue for the
six-month period ended June 30, 1997 as compared to the same period in the
prior year was principally attributable to the same factors noted for the
three-month period. The decreases in sales of the Company's veterinary test
kits and consumables were principally a result of a program to reduce U.S.
distributor inventories of these products. This program was substantially
completed by the end of the quarter ended June 30, 1997. Decreased sales of
instruments were caused by a decline in units sold and, to a lesser extent, a
decline in average unit prices. The Company expects that instrument sales will
continue to decline as the Company's market penetration increases. The Company
expects, however, that sales of test kits and consumables will resume growth
following the one-time reduction in distributor inventories.

International revenue decreased 10% to $20.9 million in the second quarter of
1997, and 2% to $42.4 million for the six months ended June 30, 1997, compared
to $23.2 million and $43.3 million, respectively, for the prior year periods.
Revenues decreased by 11% and 10% in Europe, and decreased by 23% and increased
by 3% in the Pacific Rim region (Japan, Asia, Australia) for the three- and
six-month periods ended June 30, 1997, respectively, compared to the same
periods in 1996. These decreases were offset in part by increases in revenue in
Canada and South America. Revenue from the Company's European subsidiaries,
transacted in local currencies, decreased approximately 6% and 5% for the
three- and six-month periods ended June 30, 1997, respectively, as compared to
the same periods in 1996. In U.S. dollars, the revenue decrease was 11% to
$13.2 million for the current three-month period and 10% to $26.5 million for
the current six-month period. Revenue from the Company's Pacific Rim region,
transacted in local currencies, decreased approximately 20% for the three month
period ended June 30, 1997 and increased 11% for the six-month period ended
June 30, 1997, as compared to the same periods in 1996. In U.S. dollars, the
revenue decrease was 23% to $4.3 million for the current three-month period and
the revenue increase was 3% to $9.1 million for the current six-month period.
Revenues in Europe for the three- and six-month periods decreased primarily due
to a decline in the number of instruments sold, and a decline in sales of
veterinary test kits resulting primarily from increased competition. Revenues
in the Pacific Rim increased 3% for the six-month period ended June 30, 1997
primarily due to increased sales of veterinary test products in Japan, and
decreased in the three-month period primarily due to lower sales in Japan of
veterinary test products and, to a lesser extent, instruments.

Gross profit as a percentage of revenue was 49% and 51% for the three- and
six-month periods ended June 30, 1997, respectively, and 57% for the same
periods in 1996. The decrease in gross profit as a percentage of revenue was
principally attributable to a decline in sales of the Company's higher margin
veterinary test products and a decline in the average unit price of the
instruments sold. Gross margin was also adversely affected by the inclusion of 
lower margin veterinary laboratory service revenues as a result of acquisitions
completed in 1996.

Sales and marketing expenses were 32% and 31% of revenue for the three- and
six-month periods ended June 30, 1997, respectively, compared to 24% and 26% for
the same periods in 1996. The increase as a percentage of revenue for the three-
and six-month periods ended June 30, 1997 in comparison to the same period in
1996 was principally attributable to certain fixed costs remaining constant
while sales of veterinary test kits, instruments and consumables declined. The
increases of $2.5 million and $5.0 million for the three- and six-month periods
ended June 30, 1997, respectively, over the same periods in the prior year were
principally attributable to the additional sales and marketing expenses
resulting from the acquisition of the veterinary laboratory businesses in 1996.

Research and development expenses were 7% and 6% of revenue for the three- and
six-month periods ended June 30, 1997 compared to 5% for the same periods in
1996. In dollars, such expenses increased 25% and 24% for the three- and
six-month periods ended June 30, 1997, respectively, as compared to the same
period in 1995, reflecting additional resources and related overhead to support
product development.


                                    Page 12

General and administrative expenses were 20% and 18% of revenue for the three-
and six-month periods ended June 30, 1997, respectively, compared to 11% and
10%, respectively, for the same periods in the prior year. The dollar increase
of $4.6 million and $10.1 million for the three- and six-month periods ended
June 30, 1997 in comparison to the same period in 1996 are principally
attributable to additional operating expense and acquisition costs associated
with the acquisition of the veterinary laboratory businesses, additional
operating expenses associated with business expansion, higher provision for
uncollectible accounts and higher legal expenses. As a percentage of sales,
general and administrative expenses increased due to these factors and to lower
revenues.

Net interest income was $1.7 million and $3.5 million for the three- and
six-month periods ended June 30, 1997 as compared to $2.3 million and $4.6
million for the same periods in 1996. The decrease in interest income from the
same periods in the prior year is due to the use of previously invested cash in
acquiring the veterinary laboratory businesses and other businesses since the
first quarter of 1996.

The Company's effective tax rate was 42% and 43% for the three- and six-month
periods ended June 30, 1997 compared to 41% for the same periods in 1996. The
increase in the effective tax rates is principally attributable to losses in
countries where effective tax rates exceed 41%.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 1997, the Company had cash, cash equivalents, and short-term
investments of $158.4 million and $229.4 million of working capital.

The Company believes that current cash and short-term investments and funds
expected to be generated from operations will be sufficient to fund the
Company's operations for the foreseeable future.

FUTURE OPERATING RESULTS

The future operating results of the Company are subject to a number of factors,
including without limitation, the following:

The Company's business has grown significantly over the past several years as a
result of both internal growth and acquisitions of products and businesses. The
Company has consummated a number of acquisitions since 1992, including six
acquisitions in 1996 and four acquisitions to date in 1997, and may make
additional acquisitions. Identifying and pursuing acquisition opportunities,
integrating acquired products and businesses, and managing growth requires a
significant amount of management time and skill. There can be no assurances that
the Company will be effective in identifying and effecting attractive
acquisitions, assimilating acquisitions or managing future growth.

The Company has experienced and may experience in the future significant
fluctuations in its quarterly operating results. Factors such as the
introduction and market acceptance of new products and services, the demand for
existing products and services, the mix of products and services sold and the
mix of domestic versus international revenue could contribute to this quarterly
variability. The Company operates with relatively little backlog and has few
long-term customer contracts and substantially all of its product and service
revenue in each quarter results from orders received in that quarter, which
makes the Company's financial performance more susceptible to an unexpected
downturn in business and more unpredictable. In addition, the Company's expense
levels are based in part on expectations of future revenue levels, and a
shortfall in expected revenue could therefore result in a disproportionate
decrease in the Company's net income.

The markets in which the Company competes are subject to rapid and substantial
technological change. The Company encounters, and expects to continue to
encounter, intense competition in the sale of its current and future products
and services. Many of the Company's competitors and potential competitors have
substantially greater capital, manufacturing, marketing, and research and
development resources than the Company.

The Company's future success will depend in part on its ability to continue to
develop new products and services both for its existing markets and for any new
markets the Company may enter in the future. The Company believes that it has
established a leading position in many of the markets for its animal health
diagnostic products and services, and the maintenance and any future growth of
its position in these markets is dependent upon the 


                                    Page 13
   14

successful development and introduction of new products and services. The
Company also plans to devote significant resources to the growth of its
veterinary laboratory business and its business in the food, hygiene and
environmental markets and to the development of an animal pharmaceutical product
business, where the Company's operating experience and product and technology
base are more limited than in its animal health diagnostic product markets.
There can be no assurance that the Company will successfully complete the
development and commercialization of products and services for existing and new
businesses.

The Company's success is heavily dependent upon its proprietary technologies.
The Company relies on a combination of patent, trade secret, trademark and
copyright law to protect its proprietary rights. There can be no assurance that
the patent applications filed by the Company will result in patents being
issued, that any patents of the Company will afford protection against
competitors with similar technologies, or that the Company's non-disclosure
agreements will provide meaningful protection for the Company's trade secrets
and other proprietary information. Moreover, in the absence of patent
protection, the Company's business may be adversely affected by competitors who
independently develop substantially equivalent technologies. In addition, the
Company licenses certain technologies used in its products from third parties,
and the Company may be required to obtain licenses to additional technologies in
order to continue to sell certain products. There can be no assurance that any
technology licenses which the Company desires or is required to obtain will be
available on commercially reasonable terms.

From time to time the Company receives notice alleging that the Company's
products infringe third party proprietary rights. Patent litigation frequently
is complex and expensive and the outcome of patent litigation can be difficult
to predict. There can be no assurance that the Company will prevail in any
infringement proceedings that have been or may be commenced against the Company,
and an adverse outcome may preclude the Company from selling certain products or
require the Company to pay damages or make additional royalty or other payments
with respect to such sales. In addition, from time to time other types of
lawsuits are brought against the Company, wherein an adverse outcome could
adversely affect the Company's results of operations.

Certain components used in the Company's products are currently available from
only one source and others are available from only a limited number of sources.
The Company's inability to develop alternative sources if and as required in the
future, or to obtain sufficient sole or limited source components as required,
could result in cost increases or reductions or delays in product shipments.
Certain technologies licensed by the Company and incorporated into its products
are also available from a single source, and the Company's business may be
adversely affected by the expiration or termination of any such licenses or any
challenges to the technology rights underlying such licenses. In addition, the
Company currently purchases or is contractually required to purchase certain of
the products that it sells from one source. Failure of such sources to supply
product to the Company may have a material adverse effect on the Company's
business.

For the six months ended June 30, 1997, international revenue was $42.4
million, or 35% or total revenue, and the Company expects that its
international business will continue to account for a significant portion of
its total revenue. Foreign regulatory bodies often establish product standards
that my be different from those in the United States, and designing products in
compliance with such foreign standards may be difficult or expensive. Other
risks associated with foreign operations include possible disruptions in
transportation of the Company's products, the differing product and service
needs of foreign customers, difficulties in building and managing foreign
operations, fluctuations in the value of foreign currencies, import/export
duties and quotas, and unexpected regulatory, economic or political changes in
foreign markets.

The development, manufacturing, distribution and marketing of certain of the
Company's products and provision of its services, both in the United States and
abroad, are subject to regulation by various domestic and foreign governmental
agencies. Delays in obtaining, or the failure to obtain, any necessary
regulatory approvals could have a material adverse effect on the Company's
future product and service sales and operations. Any acquisitions of new
products, services and technologies may subject the Company to additional areas
of government regulations.

The development, manufacture, distribution and marketing of the Company's
products and provision of its services involve an inherent risk of product
liability claims and associated adverse publicity. Although the Company
currently maintains liability insurance, there can be no assurance that the
coverage limits of the Company's insurance policies will be adequate. Such
insurance is expensive, difficult to obtain and may not be available in the
future on acceptable terms or at all.

PART II -- OTHER INFORMATION


     Item 1. -- LEGAL PROCEEDINGS
                -----------------

     On February 4, 1993, the Company acquired Environetics, Inc.
     ("Environetics"), which brought a patent infringement suit with Stephen
     Edberg, Ph.D. against Millipore Corporation ("Millipore") in the U.S.
     District Court for the District of Connecticut on September 30, 1992 (the
     "Millipore I suit"). The complaint in the Millipore I suit was subsequently
     amended to add as additional plaintiffs Access Medical Systems, Inc., a
     subsidiary of the Company ("Access"), and Stephen C. Wardlaw, M.D. The
     primary relief sought by the plaintiffs is an injunction against Millipore
     which would prevent Millipore from selling a competitive product that the
     plaintiffs believe infringes U.S. Patent No. 4,925,789 (the "'789 Patent")
     covering the Company's Colilert product, under which Access and
     Environetics have an exclusive license from Drs. Edberg and Wardlaw.
     Millipore has filed a counterclaim alleging that the '789 Patent is invalid
     or not infringed.

     In addition, on July 26, 1995, the Company, Environetics, Access and Drs.
     Edberg and Wardlaw brought a second patent infringement suit against
     Millipore in the U.S. District Court for the District of Connecticut (the
     "Millipore II suit"). The principal relief sought by the plaintiffs in the
     Millipore II suit is an injunction against Millipore which would prevent
     Millipore from selling a product which the plaintiffs believe infringes
     U.S. Patent No. 5,429,933 (the "'933 Patent"), which also covers the
     Colilert product. The '933 Patent, which is related to the '789 Patent, was
     issued in July 1995 to Dr. Edberg. Access and Environetics have an
     exclusive license under the '933 Patent from Drs. Edberg and Wardlaw.
     Millipore has filed a counterclaim alleging that the '933 Patent is invalid
     or not infringed.

     If the plaintiffs do not prevail in the Millipore I and Millipore II suits,
     the Company anticipates that the Colilert product would encounter 
     increased competition, which could adversely affect sales of the Colilert 
     product.

     On February 24, 1995, CDC Technologies, Inc. ("CDC Technologies") filed
     suit against the Company in the U.S. District Court for the District of
     Connecticut. In its complaint, CDC Technologies alleges that the Company's
     conduct in, and its relationships with its distributors in connection with,
     the distribution of the Company's hematology products (i) violate federal
     and state antitrust statutes, (ii) violate Connecticut statutes regarding
     unfair trade practices, and (iii) constitute a civil conspiracy and
     interfere with CDC Technologies' business relations. The relief sought by
     CDC Technologies includes treble damages for antitrust violations as well
     as compensatory and punitive damages, and an injunction to prevent the
     Company from interfering with CDC Technologies' relations with
     distributors. The Company has filed an answer denying the allegations in
     CDC's complaint. The Company is unable to assess the likelihood of an 
     adverse result or estimate the amount of any damages which the Company may
     be required to pay. Any adverse outcome resulting in the payment of 
     damages would adversely affect the Company's results of operations.

     On May 26, 1995, The Jewish Hospital of St. Louis (the "Hospital") brought
     a suit against the Company which is currently pending in the U.S. District
     Court for the District of Maine for infringement of U.S. Patent No.
     4,839,275 issued June 13, 1989 (the "'275 Patent"). The '275 Patent, which
     is owned by the Hospital, claims certain methods and compositions for the
     diagnosis of canine heartworm infection. The primary relief sought by the
     Hospital is an injunction against the Company which would prevent the
     Company from selling canine heartworm diagnostic products which infringe
     the '275 Patent, as well as treble damages for past infringement. In June
     1997, the court ruled, in response to a summary judgment motion by the
     Jewish Hospital, that five heartworm diagnostic kits formerly sold by IDEXX
     literally infringe two claims of the '275 Patent. While the Company
     believes that it has meritorious defenses in this matter, the Company is
     unable to assess the likelihood of an adverse result or estimate the 
     amount of any damages which the Company may be required to pay. If the
     Company is precluded from selling canine heartworm diagnostic products or
     required to pay damages or make additional royalty or other payments with
     respect to such sales, the Company's business and results of operations
     could be materially and adversely affected.

     On September 18, 1995, Purisys Inc. ("Purisys"), a producer of home
     pollution test kits, and certain of its employees filed suit against the
     Company in the Supreme Court of the state of New York. In their complaint,
     the plaintiffs allege that the Company has breached promises and made
     negligent misrepresentations, and has breached fiduciary and other duties.
     The plaintiffs are seeking damages in excess of $50,000,000. The Company
     purchased a 15% equity interest in Purisys in August 1994 for $616,000, and
     the Company subsequently advanced additional amounts to Purisys to purchase
     certain international distribution rights. In March 1995, the Company
     ceased advancing funds to Purisys, which filed for protection under the
     Bankruptcy Code in July 1995. In May 1996, the court granted the Company's 
     motion to dismiss the plaintiffs' suit, and the plaintiffs' appeals of
     that dismissal were dismissed by the court in July 1997. While the Company
     believes it has meritorious defenses, the Company is unable to assess the
     likelihood of an adverse result or estimate the amount of any damages
     which the Company may be required to pay. Any adverse outcome resulting in
     the payment of damages would adversely affect the Company's results of
     operations.

     Item 5.  --  OTHER INFORMATION

     On March 27, 1997, the Compensation Committee of the Company's Board of
     Directors approved a stock option exchange program, pursuant to which
     employees holding stock options issued in 1995, 1996 and 1997 under the
     Company's 1991 Stock Option Plan were given the opportunity to exchange the
     unexercised portion of such options (the "Existing Options") for new
     options (the "New Options"). The New Options cover between 50% and 100% of
     the unexercised portion of an employee's Existing Options and have an
     exercise price of $17.35 per share (which is equal to 125% of the fair
     market value of the Company's Common Stock on such date). The percentage of
     Existing Options covered is based upon the employee's position with the
     Company at the time the option grants were made in 1997, and decreases as
     employee rank increases. The New Options have terms similar to the Existing
     Options, but are not exercisable (except in certain circumstances) until
     October 31, 1997.

     The Company uses stock options as a significant element of the
     compensation of employees, in part because it believes options provide an
     incentive to employees to maximize stockholder value. Stock options,
     because they become exercisable over time, also serve as a means of
     retaining employees. Because the market value of the Company's Common
     Stock has fallen below the exercise price of the outstanding options
     issued in 1995, 1996 and 1997, the value of such stock options as a means
     of motivation and retaining employees has been significantly diminished.   
     Accordingly, the Compensation Committee of the Company's Board of
     Directors concluded that the Company needed to restore the value of the
     existing stock options as a means of motivating, retaining and providing
     incentive to employees in order to promote the successful implementation
     of the Company's growth strategies.
