                    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 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):

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 the
      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 months ended
      March 31, 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.

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 in the three
      month period ended March 31, 1997 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 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 and is seeking to add a counterclaim alleging
      misappropriation of trade secrets.

      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.
      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 complaint was dismissed as to Purisys in April 1997, but remains
      pending as to the other plaintiffs, who are seeking damages in excess of 
      $50.0 million. 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. 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.

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 a period 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 each of 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:

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

          -    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.

          -    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.



                                     Page 9

   10


          -    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.

          -    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 a part of 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 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 each of 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:

          -    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
               cultured media.

          -    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.

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 first quarter of 1997 increased 5% to $60.5 million from
$57.4 million for the first quarter of 1996. The increase in total revenue was
principally attributable to increases in veterinary laboratory services
resulting from acquisitions of veterinary reference laboratories and food and
environmental businesses principally resulting from the acquisition of Idetek.
However, the Company experienced decreased sales of veterinary testing
instruments and certain veterinary test products. The decreases in sales of the
Company's veterinary test products were principally a result of a program to 
reduce distributor inventories of these products.

International revenue increased 7% to $21.5 million in the first quarter of
1997 compared to $20.1 million in the first quarter of 1996. Revenues increased 
by 49% or $1.6 million in the Pacific Rim region (Japan, Asia, Australia) and
63% or $1.0 million in Canada for the three months ended March 31, 1997
compared to the same period in 1996. Revenues decreased 10% or $1.5 million in
Europe for the same period in 1997 versus 1996.

Revenues in the Pacific Rim transacted in local currencies increased 61%, while
revenues in Europe, transacted in local currencies, decreased only 4% for the
three months ended March 31, 1997 compared to the same period in 1996.

Gross profit as a percentage of revenue was 52% for the three month period ended
March 31, 1997 compared to 57% for the same period 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.

Sales and marketing expenses were 30% of revenue for the three month period
ended March 31, 1997 compared to 27% in the first quarter of 1996. The dollar
increase of $2.5 million in the first quarter of 1997 compared to the same
period in 1996 is 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 6% of revenue for the three months ended 
March 31, 1997 compared to 5% of revenue for the same period in 1996. In
dollars, such expenses increased 24% for the three months ended March 31, 1997
as compared to the same period in 1996, reflecting additional resources and
related overhead to support product development.

General and administrative expenses increased from 8% to 17% of revenue for the
three month period ended March 31, 1997 as compared to the same period in 1996.
The dollar increase of $5.4 million in the first quarter of 1997 compared to the
same period in 1996 is principally attributable to additional operating expenses
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.

Net interest income was $1.8 million for the three month period ended March 31,
1997 compared to $2.3 million for the same period in 1996. The decrease in
interest income over the prior year is due to the use of previously invested
cash in acquiring the veterinary laboratory and other businesses since the 
first quarter of 1996.

The Company's effective tax rate was 40% for the three month period ended March
31, 1997 compared to 41% for the same period in 1996. The decrease in the
effective tax rate was principally attributable to income generated in states
with lower state income tax rates.

LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 1997 the Company had cash, cash equivalents, and short-term
investments of $143.4 million and $225.6 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 two 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 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 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
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. 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.




                                     Page 12


   13

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, 1997, international revenue increased 7%
over the same period in 1996 to $21.5 million, or 36% 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.

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 and is seeking to add a counterclaim alleging
      misappropriation of trade secrets.

      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 Technologies' 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.
      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 complaint was dismissed as to Purisys in April 1997 but remains
      pending as to the other plaintiffs, who are seeking damages in excess 
      of $50.0 million. 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. 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
