         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.

        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.

        Notes to Condensed Consolidated Financial Statements (continued)

Note 7-  In August 1998, the Company entered into a purchase and sale agreement
         to sell certain assets and stock of its Packaging Coatings business and
         Dexter SAS to The Valspar Corporation. The sale of these businesses was
         subject to regulatory approval and customary closing conditions. This
         transaction was completed in February 1999 with total proceeds of $225
         million subject to post-closure adjustments.

         In January 1999, the Company divested its 40% interest in Akzo Dexter
         Aerospace Finishes VoF, a joint venture between the Company and Akzo
         Nobel NV, to Akzo Nobel NV for approximately book value.

Note 8-  In December 1998, Dexter acquired an additional 22% ownership of LTI.
         As a result of the acquisition, Dexter owns an aggregate of
         approximately 71% of the total number of issued and outstanding shares
         of LTI.

         The following unaudited pro forma information presents the results of
         operations of the Company as if the acquisition had taken place on
         January 1, 1998.

         These unaudited pro forma results have been prepared for comparative
         purposes only and include certain adjustments, such as the charges for
         acquired-in-process research and development and transaction costs,
         additional amortization expense, and increased interest expense on
         acquisition debt. They do not purport to be indicative of the results
         of operations which actually would have resulted had the acquisition
         occurred on the date indicated, or which may result in the future.

Note 9-  Assets in the Specialty Polymers segment at June 30, 1999 were $261.3
         million, a decrease of $156.7 million, compared with $418 million at
         December 31, 1998. This decrease was primarily due to the divestiture
         of the Packaging Coatings business, including Dexter SAS, in February
         1999.

         Assets in the Life Sciences segment at June 30, 1999 were $333.3
         million, an increase of $35.8 million, compared with $297.5 million at
         December 31, 1998. This increase was primarily due to the acquisition
         by LTI of a process chromatography and research products business in
         May 1999, and capital expenditures, net of depreciation.

        Notes to Condensed Consolidated Financial Statements (continued)

Note 10 - 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, 1999, $0.3
          million of current and $5 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. It is reasonably possible that some of the potential
          claims and legal actions that may be asserted against LTI could be
          decided unfavorably to LTI and, if so, this could have a material
          adverse effect on the Company's operating results or cash flows in
          future reporting periods. 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, 1999 and 1998, and the related condensed
statements of income and comprehensive income for 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 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, 1998, 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 9, 1999, 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, 1998 is fairly stated, in all material
respects, in relation to the consolidated statement of financial position from
which it has been derived.
