                   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, 1995 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 consolidated
            financial statements to conform with the current year's
            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:

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.

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 September 30, 1996 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
      (which have been consolidated for trial), 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 




                                     Page 7

   8

      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 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 Chapter 11 of the Bankruptcy Code in July 1995. In May 1996, the
      court granted IDEXX's motion to dismiss the plaintiffs' suit, however the
      plaintiffs have sought to appeal the dismissal and to amend their
      complaint. 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

      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. These businesses were
      acquired by the Company for aggregate purchase prices equaling
      approximately $19.7 million in cash, 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., which operates 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., which operates veterinary
                  reference laboratories in Colorado, Illinois and Oklahoma.

            -     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 ("Ubitech"), located in Uppsala,
                  Sweden, which manufactures and distributes diagnostic test
                  kits for the livestock industry.

      In connection with the Company's acquisiton 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, manufactures and distributes 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.

      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 third quarter of 1996 increased 43% to $69.8 million from
$48.7 million for the third quarter of 1995. Total revenue for the nine months
ended September 30, 1996 increased 44% to $193.1 million from $134.4 million for
the first nine months of 1995.

The increase in total revenue for the quarter ended September 30, 1996 compared
to the same period in 1995 was principally attributable to increased sales of
veterinary laboratory services resulting from recent acquisitions of veterinary
reference laboratories, veterinary clinical chemistry consumables, and test kits
for canine heartworm. The increase in total revenue for the nine-month period
ended September 30, 1996 as compared to the same period in the prior year was
attributable to increases in sales of veterinary clinical chemistry consumables,
veterinary laboratory services, canine test products, and a quantitative thyroid
instrument introduced in the first quarter of 1996. Price increases in the
veterinary clinical products also contributed to the increase in total revenue
during the three- and nine-month periods ending September 30, 1996.

International revenue increased 47% to $23.5 million in the third quarter of
1996 and 47% to $66.8 million for the nine months ended September 30, 1996, as
compared to $16.0 million and $45.5 million, respectively, for the prior year
periods. Increased revenue in Europe, which included revenue of Grange
Laboratories acquired in the second quarter of 1996 and Ubitech acquired in the
current quarter, accounted for 44% and 49% of the increase in international
revenue and increased revenue in Japan accounted for 32% and 31% of the increase
in international revenue for the three- and nine-month periods ended September
30, 1996, respectively, compared to the same periods in 1995. The remaining
increase was primarily attributable to increased revenues in Canada, Australia,
and Asia. Revenue of the Company's European subsidiaries, transacted in local
currencies, increased 34% and 36% for the three- and nine-month periods ended
September 30, 1996, respectively, as compared to the same periods in the prior
year. In U.S. dollars, the revenue increase was 30% to $14.4 million for the
current three-month period and 31% to $44.0 million for current nine-month
period.

Gross profit as a percentage of total revenue was 58% and 57% for the three- and
nine-month periods ended September 30, 1996, respectively, as compared to 57%
and 58% for the same periods in the prior year. The gross profit percentage is
higher for the three-month period ended September 30, 1996 in comparison to the
same period in 1995 because operating and purchasing efficiencies and higher
selling prices of certain veterinary clinical chemistry products exceeded the
unfavorable impact of product mix, which resulted principally from lower margins
generated by the recently acquired veterinary reference laboratories. The gross
profit percentage is lower for the nine-month period ended September 30, 1996 in
comparison to the same period in 1995 because higher selling prices for certain
veterinary clinical chemistry products were offset by product mix, as revenue
growth of lower margin veterinary clinical consumables and veterinary laboratory
services exceeded the revenue growth in higher margin diagnostic kit products.

Sales and marketing expenses were 25% and 26% of total revenue for the three-
and nine-month periods ended September 30, 1996, respectively, compared to 24%
and 25% for the same periods in 1995. The increase as a percentage of total
revenue for the three months ended September 30, 1996 in comparison to the same
period in 1995 was principally attributable to increased expenses for marketing
programs related to the Company's veterinary products. The increases of $5.6
million and $15.0 million for the three- and nine-month periods ended September
30, 1996, respectively, over the same periods in 1995 were principally
attributable to additional personnel in sales functions worldwide.

Research and development expenses were 4% and 5% of total revenue for the three-
and nine-month periods ended September 30, 1996, respectively, compared to 5%
and 6% for the same periods in 1995. The increases of $583,000 and $1.3 million
for the three- and nine-month periods ended September 30, 1996, respectively,
over the same periods in 1995 reflected additional resources and related
overhead to support product development.

General and administrative expenses were 10% of total revenue for the three- and
nine-month periods ended September 30, 1996 compared to 9% for the same periods
in 1995. The increases of $2.9 million and $6.7 million for the three- and
nine-month periods ended September 30, 1996, respectively, over the same periods
in 1995, were principally attributable to additional operating expenses and
acquisition costs associated with recent acquisitions and higher legal expenses.

Net interest income was $1.8 million and $6.3 million for the three- and
nine-month periods ended September 30, 1996, respectively, as compared to
$444,000 and $1.6 million for the same periods in 1995. The increase in interest
income is due to higher invested cash balances, due in large part to a public
stock offering in September 1995 that generated approximately $153.0 million in
net proceeds.

The Company's effective tax rate was 41% for the three- and nine-month periods
ended September 30, 1996, as compared to 42% for the same periods in 1995. The
decrease in the effective tax rate is principally attributable to lower state
income taxes.

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 1996 the Company had cash, cash equivalents, and short-term
investments of $170.1 million and $238.2 million of working capital.

The Company believes that current cash and short-term investments, which include
net proceeds from the offering of the Company's Common Stock in 1995, and funds
expected to be generated from operations, will be sufficient to fund the
Company's operations for the foreseeable future.

FORWARD LOOKING INFORMATION

This report includes certain forward-looking statements about the Company's
business including, without limitation, the belief that the Company's current
cash and short-term investments will be sufficient to fund its on-going
operations for the foreseeable future and that the Company has meritorious
defenses to certain of its litigation matters. Such forward-looking statements
are subject to risk and uncertainties that could cause the Company's actual
results to vary materially from that indicated from such forward-looking
statements. These risks and uncertainties, discussed in more detail in the
Company's Form 10-K for the year ended December 31, 1995, include those
associated with significant growth of the Company's business, internally and by
acquisition; possible significant fluctuations in quarterly operating results;
high levels of competition in existing and new markets, including the
difficulties of entering new markets; the protection and acquisition of
proprietary technologies; the availability of products from sole or limited
sources; the risks associated with conducting business internationally;
achieving regulatory approvals; significant product liability, and factors
affecting the business segments in which the Company operates and the economy
generally.

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
      (which have been consolidated for trial), 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 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 Chapter 11 of the Bankruptcy Code in July 1995. In May 1996, the
      court granted IDEXX's motion to dismiss the plaintiffs' suit, however the
      plaintiffs have sought to appeal the dismissal and to amend their
      complaint. 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.
