              Notes to Condensed Consolidated Financial Statements


Note 1 -   In the opinion of the Company's management, the unaudited condensed
           consolidated financial statements reflect adjustments of a normal
           recurring nature which are necessary to present fairly the results
           for the interim periods. The notes to the condensed consolidated
           financial statements, including management's discussion in Part 1,
           Item 2 of this Form 10-Q, are incorporated as part of these condensed
           consolidated financial statements. The year-end condensed balance
           sheet data was derived from the audited financial statements.

           share and diluted earnings per share for the three-month periods

Note 3 -   In September 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 March 31, 2000 were $320.8 million, an
           increase of $58.3 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.

        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 March 31,
           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 March 31, 2000 and 1999, and the related condensed
statements of income, comprehensive income, and cash flows for the three-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.
