                   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, 1998 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 1998 consolidated
         financial statements to conform with the current year's presentation.

     c.  The Company accounts for cash equivalents and marketable securities in
         accordance with Statement of Financial Accounting Standards No. 115
         "Accounting for Certain Investments in Debt and Equity Securities".
         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):

     e.  The Company reports earnings per share in accordance with Statement of
         Financial Accounting Standards No. 128 "Earnings per Share." 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 unless the effect is
         anti-dilutive and for the addition of shares to be issued in connection
         with the acquisition of Blue Ridge Pharmaceuticals, Inc.

         The following is a reconciliation of shares outstanding for basic and
         diluted earnings per share:



                                                                    1999     1998
                                                                   ------   ------

                                                                      
         Shares outstanding for basic earnings per share:

             Pharmaceuticals, Inc.                                    115       --
                                                                   ------   ------
                                                                   40,902   39,345
                                                                   ======   ======


3.   NON-RECURRING OPERATING CHARGE

     During 1997 the Company recorded a non-recurring operating charge of $34.5
     million. The non-recurring operating charge included a $13.2 million
     write-off of in-process research and development associated with the
     acquisition of two veterinary practice information management software
     providers and $21.3 million of the write-downs and write-offs of certain
     assets and accrual of costs related to a significant workforce reduction.

     As of March 31, 1999, $2.3 million was included in accrued expenses
     relating to the non-recurring operating charge. The balance remaining at
     March 31, 1999 primarily represents severance payments due to terminated
     employees, unpaid charges related to the consolidation and relocation of
     distribution functions in Europe and lease payments on unutilized
     facilities.

4.   COMPREHENSIVE INCOME

     The Company reports comprehensive income in accordance with Statement of
     Financial Accounting Standards No. 130 "Reporting Comprehensive Income."
     Other comprehensive income for the Company consists of foreign currency
     translation adjustments resulting from the translation of the financial
     statements of the Company's foreign subsidiaries. The Company considers the
     foreign currency cumulative translation adjustment to be permanently
     invested and therefore has not provided income tax on those amounts.
     Accordingly, below is a summary of comprehensive income in accordance with
     this statement (in thousands):

5.   NOTES PAYABLE

     In connection with the acquisition of the business of Consolidated
     Veterinary Diagnostics, Inc., the Company issued an unsecured note payable
     for $3.0 million, of which $2.0 million and $1.0 million was outstanding at
     March 31, 1998 and 1999, respectively. The note bears interest at 8% and is
     due in three equal installments in July 1997, 1998 and 1999.

     In connection with the Central Veterinary Diagnostic Laboratory
     acquisition, the Company issued an unsecured note payable for Australian
     Dollars 900,000 (US $587,000) of which Australian Dollars 675,000 (US
     $430,700) was outstanding at March 31, 1999. The note bears interest at 6%
     and is due in four equal annual installments beginning in December 1998.

     In connection with the Blue Ridge Pharmaceuticals, Inc. acquisition (see
     Note 7b), the Company issued unsecured notes payable for $7,830,000, which
     were outstanding at March 31, 1999. The notes bear interest at 5.5% and are
     due in two equal annual installments on October 1, 1999 and 2000.

     In connection with the acquisition of a veterinary laboratory business in
     Phoenix, Arizona (see Note 7c), the Company issued a non-interest bearing
     note payable for $538,935 which was outstanding at March 31, 1999. The note
     is due in five monthly installments beginning in April 1999.

6.   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 filed by Synbiotics
     Corporation, the Company is not aware of any pending litigation 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 in the three month
     period ended March 31, 1999 was attributable to products incorporating
     certain immunoassay technologies and products relating to the diagnosis of
     canine heartworm infection. 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 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. In March 1998, the court granted the Company's motion for
     summary judgment in the case, however CDC is appealing that ruling. 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 November 12, 1998, Synbiotics Corporation ("Synbiotics") filed suit
     against the Company in the U.S. District Court for the Southern District of
     California for infringement of U.S. Patent No. 4,789,631 issued December 6,
     1988 (the "`631 Patent"). The `631 Patent, which is owned by Synbiotics,
     claims certain assays, methods and compositions for the diagnosis of canine



                                       8
   9

     heartworm infection. The primary relief sought by Synbiotics is an
     injunction against the Company which would prevent the Company from selling
     canine heartworm diagnostic products which infringe the `631 Patent, as
     well as treble damages for past infringement. This suit was not served on
     the Company within the time period specified under applicable court rules
     and was dismissed without prejudice in April 1999, however Synbiotics is
     not precluded from filing a new suit in the future. While the Company
     believes that it has meritorious defenses against claims of infringement of
     the `631 Patent, the Company is unable to assess the likelihood of an
     adverse result or estimate the amount of any damages 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 January 9, 1998, a complaint was filed in the U.S. District Court for
     the District of Maine captioned ROBERT A. ROSE, et.al. v. DAVID E. SHAW,
     ERWIN F. WORKMAN, JR. and IDEXX LABORATORIES, INC. The plaintiffs purport
     to represent a class of purchasers of the common stock of the Company from
     July 19, 1996 through March 24, 1997. The complaint claims that the
     defendants violated Section 10(b) of the Securities Exchange Act of 1934
     and Securities and Exchange Commission Rule 10b-5 promulgated pursuant
     thereto, by virtue of false or misleading statements made during the class
     period. The complaint also claims that the individual defendants are liable
     as "control persons" under Section 20(a) of that Act. In addition, the
     complaint claims that the individual defendants sold some of their own
     common stock of the Company, during the class period, at times when the
     market price for the stock allegedly was inflated. While the Company and
     other defendants deny the allegations and will defend this suit vigorously,
     the Company is unable to assess the likelihood of an adverse result or
     estimate the amount of 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 December 18, 1997, SA Scientific, Inc. ("SAS") filed suit against the
     Company in the State of Texas District Court seeking unspecified damages
     resulting from the Company's alleged breach of a development and supply
     agreement between SAS and the Company. The Company has filed an answer to
     the complaint denying SAS's allegations and asserting counterclaims against
     SAS for breach of contract and conversion of the Company's property. SAS
     has filed an amended complaint seeking $1,500,000 in actual damages related
     to the Company's alleged breach of contract, $5,000,000 in punitive damages
     and further unspecified damages from the Company's alleged negligent
     misrepresentation, fraud and conversion of SAS's intellectual property, and
     attorneys' fees. The Company believes that it has meritorious defenses to
     SAS's claims and is contesting the matter vigorously. However, the Company
     is unable to assess the likelihood of an adverse result or estimate the
     amount of damages the Company might be required to pay. Any adverse outcome
     resulting in payment of damages would adversely affect the Company's
     results of operations.

7.   ACQUISITIONS

     1998 ACQUISITIONS

     (a) Agri-West Laboratory

     On March 1, 1998, the Company, through its wholly-owned subsidiary, IDEXX
     Food Safety Net Services, Inc., acquired certain assets and assumed
     certain liabilities of Agri-West Laboratory ("Agri-West") for $250,000
     from Agri-West International, Inc. ("AWI"). Agri-West, located in Dallas
     and San Antonio, Texas, performs food contaminant testing for food
     processors and research institutions. The Company also entered into
     employment, consulting and non-competition agreements with the owners of
     AWI for up to five years. The Company has accounted for this acquisition
     under the purchase method of accounting and has included the results of
     operations in its consolidated results of operations since the date of
     acquisition.
        
     (b) Blue Ridge Pharmaceuticals, Inc.

     On October 1, 1998, the Company acquired all of the capital stock of Blue
     Ridge Pharmaceuticals, Inc. ("Blue Ridge") for approximately $39.1 million
     in cash, $7.8 million in notes, 115,000 shares of the Company's Common
     Stock and warrants to acquire 806,000 shares of Common Stock at $31.59 per
     share which expire on December 31, 2003. In addition, the Company agreed to
     issue up to 1.24 million shares of its Common Stock based on the
     achievement by the Company's pharmaceutical business (including Blue Ridge)
     of net sales and operating profit targets through 2004. All former
     shareholders received equal value in the form of cash/notes/stock, warrants
     and contingent shares on a per share basis. The notes, which bear interest
     at 5.5% annually and are 


                                       9
   10

     due in two equal annual installments on October 1, 1999 and 2000, are due
     to certain key employees of Blue Ridge, subject to certain contingencies.
     The shares of Common Stock are issuable on October 1, 2001 to a key
     employee of Blue Ridge, subject to certain contingencies. Blue Ridge is a
     development-stage animal health pharmaceutical company located in
     Greensboro, North Carolina. The Company will record the issuance of any of
     the 1.24 million shares discussed above as additional goodwill when the
     shares are issued. The Company has accounted for this acquisition under the
     purchase method of accounting and has included the results of operations in
     its consolidated results since the date of acquisition.

     1999 ACQUISITIONS

     (c) Phoenix Veterinary Laboratory Business

     On March 31, 1999, the Company, through its wholly-owned subsidiary, IDEXX
     Veterinary Services, Inc., acquired the veterinary laboratory business of
     Sonora Quest Laboratories, LLC ("Sonora"), based in Phoenix, Arizona, for
     $1.3 million in cash and a $539,000 promissory note. In connection with the
     acquisition, Sonora and its parent companies agreed not to compete in the
     veterinary reference laboratory business in Arizona and New Mexico for a
     period of five years. The note is non-interest bearing and is due in five
     monthly installments beginning in April 1999. The Company has accounted for
     this acquisition under the purchase method of accounting and has included
     the results of operations in its consolidated results since the acquisition
     date.

8.   SEGMENT REPORTING

     The Company reports segment information in accordance with Statement of
     Financial Accounting Standards No. 131, "Disclosures About Segments of an
     Enterprise" ("SFAS 131"). SFAS 131 requires disclosures about operating
     segments in annual financial statements and requires selected information
     about operating segments in interim financial statements. It also requires
     related disclosures about products and services and geographic areas.
     Operating segments are defined as components of an enterprise about which
     separate financial information is available that is evaluated regularly by
     the chief operating decision maker, or decision making group, in deciding
     how to allocate resources and in assessing performance. The Company's chief
     operating decision maker is the chief executive officer.

     The Company is organized into business units by market and customer group.
     The Company's reportable operating segments include the Veterinary
     Solutions Group ("VSG"), the Food and Environmental Division ("FED") and
     other. The VSG develops, designs, and distributes products and performs
     services for veterinarians. The VSG also manufactures certain biology
     based test kits for veterinarians. FED develops, designs, manufactures and
     distributes products and performs services to detect disease and
     contaminants in food animals, food, water and food processing facilities.
     Both the VSG and FED distribute products and services worldwide. Other is
     primarily comprised of the Company's Blue Ridge Pharmaceuticals, Inc.
     subsidiary, which develops products for therapeutic applications in
     companion animals and livestock, corporate research and development, and
     interest income.
        
     The accounting policies of the operating segments are the same as those
     described in the summary of significant accounting policies except that
     most interest income and expense are not allocated to individual operating
     segments.
        
     The following is the segment information for the period ended March 31
     (in thousands):

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

RESULTS OF OPERATIONS

VETERINARY SOLUTIONS GROUP

Revenue for the Veterinary Solutions Group ("VSG") for the first quarter of 1999
increased 16% to $71.4 million from $61.7 million for the first quarter of 1998.
The increase in revenue in 1999 compared to 1998 is primarily attributable to
increased sales of veterinary consumables, practice information management
systems, and veterinary reference laboratory services. These increases were
offset in part by decreased unit sales of veterinary instruments.

International revenue for VSG increased 4% to $14.7 million, or 21% of total VSG
revenue, in the first quarter of 1999, compared to $14.1 million, or 23% of
total VSG revenue, in the same period for 1998. Revenue increased 14% in Europe
and 1% in Canada and South America, while revenue decreased 16% in the Asia-
Pacific region. In Europe, the increase resulted primarily from increased sales
of veterinary consumables and veterinary laboratory services. In the Asia-
Pacific region, the decrease resulted primarily from a decrease in sales of
veterinary test kits and instruments, which was partially offset by an increase
in sales of veterinary consumables.

Gross profit as a percentage of VSG revenue was 49% for both periods. Higher
sales of lower gross margin practice information management systems offset
efficiencies gained in veterinary laboratory operations and declining sales of
lower gross margin veterinary instruments.

FOOD AND ENVIRONMENTAL DIVISION

Revenue for the Food and Environmental Division ("FED") for the first quarter of
1999 increased 12% to $18.0 million from $16.1 million for the first quarter of
1998. The increase in revenue in 1999 compared to 1998 is primarily attributable
to increased sales of water testing products, food laboratory testing services
partially resulting from the acquisition of Agri-West Laboratory in March 1998,
food residue test products and livestock test kits, partially offset by
decreased sales of poultry test kits and dehydrated culture media.

International revenue for FED increased 6% to $7.6 million, or 42% of total FED
revenue, in the first quarter of 1999, compared to $7.2 million, or 45% of total
FED revenue, for the same period in 1998. Revenue increased 5% in Europe, 4% in
Canada and South America, and 11% in the Asia-Pacific region. In Europe, the
increase in revenue was primarily attributable to increased sales of food
residue testing products and poultry and livestock test kits. The increase in
revenue in the Asia-Pacific region is primarily due to increased sales of
livestock test kits and food residue testing products, partially offset by lower
sales of poultry test kits.

Gross profit as a percentage of FED revenue was 54% for the first quarter of
1999 compared to 50% for the same period in 1998. Increased sales of higher
margin water and livestock test kits were partially offset by a decline in the
average unit prices of hygiene instruments and poultry test kits and increased
revenue in lower margin food laboratory services.

OPERATING EXPENSES

Sales and marketing expenses were 17% of revenue for the three month period
ended March 31, 1999 compared to 21% in the first quarter of 1998. The decrease
as a percentage of revenue and the dollar decrease of $1.0 million were
principally attributable to a decrease in salary and related expenses resulting
from workforce reductions, partially offset by the inclusion of sales and
marketing expenses for the pharmaceutical business acquired in the last quarter
of 1998.

Research and development expenses were 8% of revenue for the three month period
ended March 31, 1999 compared to 7% in the first quarter of 1998. The increase
as a percentage of revenue and the dollar increase of $1.9 million is
principally caused by the 



                                       11
   12

addition of development expenses associated with the acquisition of Blue Ridge
Pharmaceuticals in the last quarter of 1998 and additional resources and related
overhead to support product development.

General and administrative expenses were 14% of revenue for the three month
period ended March 31, 1999 compared to 16% in the first quarter of 1998. The
dollar increase of $42,000 was primarily attributable to additional amortization
of goodwill associated with the acquisition of Blue Ridge Pharmaceuticals in the
last quarter of 1998, partially offset by a reduction in the provision for bad
debts.

Net interest income was $1.3 million for the three month period ended March 31,
1999 compared to $1.6 million for the same period in 1998. The decrease in
interest income over the prior year is due to the use of previously invested
cash in completing the acquisition of Blue Ridge Pharmaceuticals in the last
quarter of 1998.

The Company's effective tax rate was 38% for the three month period ended March
31, 1999 compared to 39% for the same period in 1998. The decrease in the
effective tax rate was principally attributable to newly available federal and
state credits for research and development activities.

LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 1999, the Company had cash, cash equivalents, and short-term
investments of $124.3 million and $183.9 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 two
acquisitions in 1998 and one acquisition to date in 1999, and plans to make
additional acquisitions. Identifying and pursuing acquisition opportunities,
integrating acquired products and businesses, and managing growth require a
significant amount of management time and skill. There can be no assurance 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 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,
veterinary practice information management software business, animal health
pharmaceuticals business and its business in the food, hygiene and
environmental markets, as well as to the development of an internet portal for
the provision of animal healthcare information and services. The Company's
operating experience and product and technology base in 



                                       12
   13

these businesses 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
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 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 in "Notes to Consolidated
Financial Statements" with respect to the patent infringement suit filed by
Synbiotics Corporation, the Company is not aware of any pending litigation 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, 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.

In the three months ended March 31, 1999, international revenue was $22.3
million, or 25% of 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 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.




                                       13
   14
YEAR 2000

Historically, certain computer programs have been written using two digits,
rather than four digits, to define the applicable year. This could lead, in many
cases, to a computer's recognizing a date using "00" as 1900 rather than the
year 2000. This phenomenon could result in major computer system failures or
miscalculations, and is generally referred to as the "Year 2000" problem or
issue. The following discussion first summarizes the Company's efforts to
identify and resolve Year 2000 issues associated with the Company's information
technology ("IT") and non-IT internal systems, the products and services sold by
the Company, and the products and services supplied by outside vendors, and then
addresses total costs, most reasonably likely worst case scenarios, contingency
plans, and the basis for current estimates relating to such efforts.

The Company's worldwide accounting system is Year 2000 ready, and throughout
1999 the Company expects to complete implementation of any needed Year 2000
related modifications to its other IT systems. The Company is also currently
assessing its internal non-IT systems and expects to complete testing and any
needed modifications to these systems prior to 2000. Although the Company does
not believe that it will incur material costs or experience material disruptions
in its business associated with preparing its internal systems for the Year
2000, there can be no assurances that the Company will not experience serious
unanticipated negative consequences and/or material costs caused by undetected
errors or defects in the technology used in its internal systems, which are
composed of third party software, third party hardware that contains embedded
software and the Company's own software products.

The Company's Year 2000 effort has included testing products currently or
recently offered by the Company for Year 2000 issues. The Company believes that
all of its current product offerings are Year 2000 Ready with the exception of
its VetTest(R) clinical chemistry analyzer. The Company has determined that some
versions of the VetTest instrument, including the current model, will not
properly display or transmit the date and time a sample is tested for dates
beginning January 1, 2000, unless the date and time is reset each time the
instrument is turned on. The Company believes that the accuracy of test results
provided by the VetTest instrument will not be affected. The Company also
believes it will be able to revise the VetTest software, which is routinely
updated and sent to all VetTest users approximately three times per year, to
enable the instrument to properly display and transmit date and time information
from and after January 1, 2000, with little if any inconvenience to users of the
VetTest instrument. For all other products that were identified as needing
updates to address Year 2000 issues, the Company has prepared updates or has
removed such products from its product offerings. Some of the Company's
customers, including users of older practice information management systems, are
using product versions that the Company will not support for Year 2000 issues;
the Company is encouraging these customers to migrate to current product
versions that are Year 2000 ready. Notwithstanding these efforts, there can be
no guarantee that one or more current Company products do not contain Year 2000
issues that may result in material costs to the Company.

Because a portion of the Company's business involves the sale of software
systems, the Company's risk of being subjected to lawsuits relating to Year 2000
issues with its software products is likely to be greater than that of companies
that do not sell software products. Because computer systems may involve
different hardware, firmware and software components from different
manufacturers, it may be difficult to determine which component in a computer
system may cause a Year 2000 issue. As a result, the Company may be subjected to
Year 2000 related lawsuits independent of whether its products and services are
Year 2000 ready. The outcomes of any such lawsuits and the impact on the Company
cannot be determined at this time.

The Company has queried its important suppliers and vendors to assess their Year
2000 readiness. To date, the Company is not aware of any problems that would
materially impact results of operations, liquidity, or capital resources.
However, the Company has no means of ensuring that these suppliers and vendors
will be Year 2000 ready. The inability of those parties to complete their Year
2000 resolution process could materially impact the Company. The Company is
currently querying key resellers of Company products regarding Year 2000
readiness. No assurances can be given regarding the state of readiness of such
resellers.

The Company's total cost relating to Year 2000 related activities has not been
and is not expected to be material to the Company's financial position, results
of operations, or cash flows. The Company believes that necessary modifications
will be made on a timely basis. However, there can be no assurance that there
will not be a delay in, or increased costs associated with, the implementation
of such modifications, or that the Company's suppliers, resellers and customers
will adequately prepare for the Year 2000 issue. It is possible that any such
delays, increased costs, or supplier, reseller or customer failures could have a
material adverse impact on the Company's operations and financial results.

The most reasonable likely worst case Year 2000 scenarios for the Company would
include: (i) the failure of infrastructure services provided by government
agencies and other third parties (e.g., electricity, phone service, water,
transport, material delivery, security systems, etc.), (ii) corruption of data
contained in the Company's internal information systems, and (iii) hardware
failure. The Company is currently developing a contingency plan in the event
certain internal or external systems, or certain of the Company's suppliers,
vendors or resellers, are not Year 2000 ready. However, if the Company does not
become Year 2000 ready in a timely manner, the Year 2000 issue could have a
material adverse impact on the Company's operations by, for example, impacting
the Company's ability to deliver products or services to its customers.

Current estimates of the costs of the project and the information on which the
Company believes it will complete the year 2000 modifications are based on
certain assumptions regarding future events, including the continued
availability of certain resources, assurances received from third parties, and
other factors. However, there can be no guarantee that these estimates will be
achieved or that this information is accurate, and therefore the actual results
could differ materially from those anticipated. Specific factors might include,
but are not limited to, the availability and cost of personnel trained in this
area, the degree of cooperation and preparedness of third parties, the ability
to locate and correct all relevant computer codes, and other uncertainties.

PART II -- OTHER INFORMATION

     Item 1. -- Legal Proceedings
                -----------------

     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. In March 1998, the court granted the Company's motion for
     summary judgment in the case, however CDC is appealing that ruling. 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 November 12, 1998, Synbiotics Corporation ("Synbiotics") filed suit
     against the Company in the U.S. District Court for the Southern District of
     California for infringement of U.S. Patent No. 4,789,631 issued December 6,
     1988 (the "`631 Patent"). The `631 Patent, which is owned by Synbiotics,
     claims certain assays, methods and compositions for the diagnosis of canine
     heartworm infection. The primary relief sought by Synbiotics is an
     injunction against the Company which would prevent the Company from selling
     canine heartworm diagnostic products which infringe the `631 Patent, as
     well as treble damages for past infringement. This suit was not served on
     the Company within the time period specified under applicable court rules
     and was dismissed without prejudice in April 1999, however Synbiotics is
     not precluded from filing a new suit in the future. While the Company
     believes that it has meritorious defenses against claims of infringement of
     the `631 Patent, the Company is unable to assess the likelihood of an
     adverse result or estimate the amount of any damages 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 January 9, 1998, a complaint was filed in the U.S. District Court for
     the District of Maine captioned ROBERT A. ROSE, et. al. v. DAVID E. SHAW,
     ERWIN F. WORKMAN, JR. and IDEXX LABORATORIES, INC. The plaintiffs purport
     to represent a class of purchasers of the common stock of the Company from
     July 19, 1996 through March 24, 1997. The complaint claims that the
     defendants violated Section 10(b) of the Securities Exchange Act of 1934
     and Securities and Exchange Commission Rule 10b-5 promulgated pursuant
     thereto, by virtue of false or misleading statements made during the class
     period. The complaint also claims that the individual defendants are liable
     as "control persons" under Section 20(a) of that Act. In addition, the
     complaint claims that the individual defendants sold some of their own
     common stock of the Company, during the class period, at times when the
     market price for the stock allegedly was inflated. While the Company and
     other defendants deny the allegations and will defend this suit vigorously,
     the Company is unable to assess the likelihood of an adverse result or
     estimate the amount of 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 December 18, 1997, SA Scientific, Inc. ("SAS") filed suit against the
     Company in the State of Texas District Court seeking unspecified damages
     resulting from the Company's alleged breach of a development and supply
     agreement between SAS and the Company. The Company has filed an answer to
     the complaint denying SAS's allegations and asserting counterclaims against
     SAS for breach of contract and conversion of the Company's property. SAS
     has filed an amended complaint seeking $1,500,000 in actual damages related
     to the Company's alleged breach of contract, $5,000,000 in punitive damages
     and further unspecified damages from the Company's alleged negligent
     misrepresentation, fraud and conversion of SAS's intellectual property, and
     attorneys' fees. The Company believes that it has meritorious defenses to
     SAS's claims and is contesting the matter vigorously. However, the Company
     is unable to assess the likelihood of an adverse result or estimate the
     amount of damages the Company might be required to pay. Any adverse outcome
     resulting in payment of damages would adversely affect the Company's
     results of operations.
