        Notes to Condensed Consolidated Financial Statements (continued)


Note 3 - In June 1998, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards (SFAS) No. 133, Accounting for
         Derivative Instruments and Hedging Activities. As issued, this
         statement is effective for all fiscal quarters of all fiscal years
         beginning after June 15, 1999. In June 1999, the Financial Accounting
         Standards Board issued Statement of Financial Accounting Standards
         (SFAS) No. 137, Accounting for Derivative Instruments and Hedging
         Activities - Deferral of the Effective Date of FASB Statement No. 133.
         This statement amends Statement No. 133 to be effective for all fiscal
         quarters of all fiscal years beginning after June 15, 2000. The Company
         is currently evaluating the impact of SFAS No. 133.

Note 6 - General corporate assets at June 30, 2000 were $340.6 million, an
         increase of $78.1 million, compared with $262.5 million at December 31,
         1999. This increase was primarily due to Dexter's increased ownership
         of LTI since year-end 1999 and higher levels of cash and short-term
         securities.

        Notes to Condensed Consolidated Financial Statements (continued)



Note 7 - The Company and its subsidiaries are subject to potential liability
         under government regulations, contractual and other matters, and
         various claims and legal actions which are pending or may be asserted.
         These matters arise in the ordinary course and conduct of the business
         of the Company and its subsidiaries and some are expected to be
         covered, at least in part, by insurance. At June 30, 2000, $0.3 million
         of current and $4.9 million of long-term receivables from third party
         insurance companies are included as assets of the Company. Equal and
         offsetting payables to third parties are included as liabilities of the
         Company.

         In September 1999, LTI submitted a report in connection with a
         voluntary disclosure to the Department of Veteran Affairs ("VA")
         regarding matters involving the management of LTI's Federal Supply
         Schedule contract with the VA that has been in effect since April 1992.
         As part of the disclosure, LTI has offered to provide a refund to the
         government in the amount of $3.9 million. There can be no assurance
         that the government will agree with LTI's assessment of this matter or
         accept LTI's offered refund amount. Consequently, it is possible the
         final resolution of this matter could materially differ from LTI's
         offer and could have material effect on the Company's financial
         position, operating results or cash flows when resolved in a future
         reporting period.

         While the outcome of all of the pending and potential claims and legal
         actions against the Company and its subsidiaries cannot be forecast
         with certainty, management believes that, with the possible exception
         of the potential liability of LTI described above, such matters should
         not result in any liability which would have a material adverse effect
         on the Company's financial position, results of operations, or cash
         flows.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Shareholders and Board of Directors of
Dexter Corporation

We have reviewed the accompanying condensed statement of financial position of
Dexter Corporation as of June 30, 2000 and 1999, and the related condensed
statements of income and comprehensive income for each of the three and
six-month periods then ended, and the condensed statement of cash flows for the
six-month periods then ended. These financial statements are the responsibility
of the company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying condensed interim financial statements for them to
be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated statement of financial position of Dexter
Corporation as of December 31, 1999, and the related consolidated statements of
income, cash flows, and changes in shareholders' equity for the year then ended
(not presented herein); and in our report dated February 28, 2000, we expressed
an unqualified opinion on those consolidated financial statements. In our
opinion, the information set forth in the accompanying condensed statement of
financial position as of December 31, 1999 is fairly stated, in all material
respects, in relation to the consolidated statement of financial position from
which it has been derived.
