ITEM 1  BUSINESS
 
GENERAL
 
     Founded in 1767 and incorporated in the state of Connecticut in 1914,
Dexter Corporation operates specialty materials businesses with leadership
positions in markets that provide opportunities for profitable growth. The
principal markets served by the Company are the worldwide aerospace,
electronics, food packaging, and medical markets. For an analysis of operations
of the business of Dexter, see pages 24 through 29 of the 1998 Annual Report,
incorporated herein by reference, which includes Life Technologies, Inc.
information on pages 26 and 27, Segment Data on pages 28 and 29, and Geographic
Information on page 29. Also, see Events, Trends and Vulnerabilities and
Acquisitions and Divestitures information on pages 22 and 23 of the 1998 Annual
report which are incorporated herein by reference.
 
     The financial information in the hereinafter mentioned pages and sections
should be read in conjunction with the Financial Statements contained on pages
16 through 20, Quarterly Financial Information on page 21, Analysis of Financial
Condition and Operations contained on pages 22 and 23, Analysis of Operations
contained on pages 24 through 29, and Analysis of Financial Position contained
on pages 30 through 39 of the 1998 Annual Report.
 
SEGMENT INFORMATION AND PRODUCTS
 
     The Company has three operating segments: Life Sciences, Nonwovens, and
Specialty Polymers. The businesses of Dexter are organized and reported based on
the commonality of the products, services and technologies employed within these
segments.
 
     The life sciences segment focuses on the development and manufacture of
precise, reproducible biological and biochemical products for life sciences
research and commercial applications within the medical market. Life
Technologies, Inc. is reported in this segment.
 
     The nonwovens segment focuses on the proprietary formulation and
manufacture of long-fiber, wet-formed, and hydroentangled products, primarily
for use in the food packaging, medical and hygiene markets. The Nonwoven
Materials business and its cogeneration facility, which provides electricity and
steam to the Nonwoven Materials, Windsor Locks, Connecticut facility, as well
as, electricity to the local utility, are reported in this segment.
 
     The specialty polymers segment includes businesses whose product offerings
are based on polymer technology for the formulation and processing of specialty
adhesives, coatings and encapsulants primarily for use in the aerospace and
electronics markets. Long-term polymer research and development for this segment
is performed at the segment's specialty polymer research and development
laboratories in San Diego, California. The Adhesive and Coating Systems
business, Electronic Materials business and Magnetic Technologies business are
reported in this segment. The Packaging Coatings business and Dexter SAS, a
French subsidiary, whose product offerings are based on polymer technology
serving the food packaging and industrial markets are also included in this
segment but were divested in February 1999. For additional information on the
divestiture of the Packaging Coatings business and Dexter SAS, refer to the
Acquisitions and Divestitures footnote on page 23 of the 1998 Annual Report
which is incorporated herein by reference.
 
     For additional information on the Company's segment and product information
refer to Segment Data on pages 28 and 29 of the 1998 Annual Report which is
incorporated herein by reference.

SUPPLIERS
 
     Dexter buys materials for its products from many suppliers and is not
dependent on any one supplier or group of suppliers for any significant raw
materials purchased.
 
     The materials bought include natural fibers such as hemp and woodpulp;
synthetic fibers such as glass, rayon and polyester; basic chemical materials
(many of which are derived from petroleum products) for the manufacture of
synthetic resins; resins produced by others, including polypropylene; solvents,
additives and pigments; highly purified chemicals and products collected from
natural sources for Life Technologies' products; and magnetic materials. For
further discussion of raw materials, see Events, Trends and Vulnerabilities on
pages 22 and 23 of the 1998 Annual Report which is incorporated herein by
reference.
 
CUSTOMERS
 
     In 1998, no single customer accounted for more than 5 percent of
consolidated revenues, and the ten largest customers accounted for less than 20
percent. Dexter has no single customer contract for the sale of its products
which it deems to be material to its business as a whole.
 
SALES AND MARKETING
 
     Dexter's customers for most specialty material products are principally
industrial manufacturers who convert or incorporate Dexter's products into their
own final product. Life science products are marketed directly to research
laboratories, pharmaceutical and biotechnology companies, and other customers.
Most of the Company's products are sold by its own sales force of which
approximately 299 were directly engaged in field sales in 1998, 275 in 1997, and
252 in 1996. The remaining products are sold through agents or distributors. In
general, each of the Company's product lines has its own sales force. Management
believes that product research and development, close customer relations and
strong technical service are important factors in Dexter's growth over the
years.
 
BACKLOG
 
     Dexter continues to maintain a backlog of orders. Such backlog was
approximately $85 million at December 31, 1998 and $77 million at December 31,
1997 and typically represents less than two months sales for businesses where
backlog is applicable. The Company expects substantially all of the December 31,
1998 backlog to be shipped in 1999. Backlog was significant in all businesses
except Life Technologies, Inc. (LTI), where backlog is not considered to be
relevant to the business. Although backlog orders are reasonably firm, they may
be subject to cancellation or delay and amounts are not necessarily indicative
of future sales volume or profitability.
 
COMPETITION
 
     No company is known to compete with Dexter in all of its major businesses,
but in each market, competition is offered by a number of companies, including
firms substantially larger and with greater financial resources than Dexter.
 
     Dexter's management believes that Dexter is an important factor in each of
its markets. All markets are diverse and highly competitive and emphasize the
quality of their products. The businesses of the Company are characterized by
technological leadership and the continual introduction of new products and
services.
 
     Dexter continues to experience competition from imports in several of its
domestic markets. For further discussion on competition, see Events, Trends and
Vulnerabilities on pages 22 and 23 of the 1998 Annual Report which is
incorporated herein by reference.
 
RESEARCH AND DEVELOPMENT
 
     Dexter engages in research and development with respect to new product
development and product applications primarily for its own use, with only minor
contract services provided for others. For further information on research and
development, see the section entitled Events, Trends and Vulnerabilities on
pages 22 and 23 of the 1998 Annual Report which is incorporated herein by
reference.
 
                                        2
<PAGE>   5
 
     The total number of employees engaged in research and development were
approximately 483, 465, and 447 at December 31, 1998, 1997 and 1996,
respectively. For information on research and development expenditures, and
acquired in-process research and development costs, see the Statement of Income
on page 16 and the Acquisitions and Divestitures footnote on page 23 of the 1998
Annual Report which are incorporated herein by reference.
 
ENVIRONMENTAL REGULATION
 
     The Company is subject to federal, state and other legal requirements
regulating the discharge of materials into the environment, or otherwise
relating to the protection of the environment. The Company does not believe that
the continuing cost of complying with such regulations and other costs related
to environmental matters will have a material adverse effect on the Company's
financial position, results of operations or cash flows. Capital expenditures
for environmental projects were $1.5 million for 1998 and are estimated to range
from $1 -- $2 million for 1999. For further discussion of other current
environmental matters, see Events, Trends and Vulnerabilities on pages 22 and 23
and the Environmental Liabilities footnote on page 33 of the 1998 Annual Report,
both of which are incorporated herein by reference. See Item 7, Management's
Discussion and Analysis of Financial Condition and Results of Operations, of
this Form 10-K, on page 7, for information on administrative proceedings arising
under the Comprehensive Environmental Response, Compensation and Liability Act
of 1980.
 
EMPLOYEES
 
     Approximately 1,800 of the Company's 5,000 employees (see page 14 of the
1998 Annual Report which is incorporated herein by reference) are employed
outside the United States. There has not been a significant work stoppage in
recent years and management believes employee relations are good.
 
GEOGRAPHIC INFORMATION
 
     For information regarding geographic operations, see Events, Trends and
Vulnerabilities on pages 22 and 23, Geographic Information on page 29, and the
Currency Exchange Effects footnote on page 33 of the 1998 Annual Report which

     Pursuant to authority granted under the "Comprehensive Environmental
Response, Compensation and Liability Act of 1980" (CERCLA), the U.S.
Environmental Protection Agency (USEPA) has issued a National Priority List of
sites at which action is to be taken to mitigate the risk of release of
hazardous substances into the environment. The Company is engaged in continuing
negotiations with the USEPA and state authorities with regard to 17 of the over
twelve hundred sites on the National Priority List. Due to the uncertainty of
the remedial measures to be adopted at various sites and the fact that
imposition of joint and several liability is possible under CERCLA, the
liability of the Company with respect to any site at which remedial measures
have not been completed cannot be established with certainty. Nevertheless,
based upon the information available at this time, the Company believes it has
properly provided for its best estimate of the liabilities and that the outcome
of these matters will not have a material adverse effect upon its financial
condition, results of operations or cash flows in the future.

IMPACT OF THE YEAR 2000
 
  General
 
     The year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year. Any of the
Company's systems, equipment, or hardware that have date-sensitive software or
embedded chips may recognize a date using "00" as the year 1900 rather than the
year 2000. This could result in a system failure or miscalculations causing
disruption of operations, including, among other things, a temporary inability
to properly manufacture products, process transactions, send invoices, or engage
in similar normal business activities.
 
     Based on its initial assessments, the Company determined that it would be
required to modify or replace portions of its equipment, hardware, and software
so that affected systems will properly utilize dates beyond December 31, 1999.
The Company presently believes that, with modifications and replacement of
existing equipment, hardware, and software, the year 2000 issue will be
mitigated.
 
  Project Plan
 
     The Company's plan to resolve the year 2000 issue is being implemented by
each of the Company's businesses and involves five phases: inventory; risk
assessment, prioritization, and ownership assignment; compliance research;
remediation; and testing. The inventory phase and the risk assessment,
prioritization and ownership assignment phase, which were performed
concurrently, are substantially complete. The compliance research phase is
expected to be substantially completed by March 31, 1999. The remediation and
testing phases are expected to be substantially completed by September 30, 1999.
Although the Company's year 2000 plan is being completed on a business by
business basis, it is estimated that the compliance research phase is 80%
complete, the remediation phase is approximately 50% to 60% complete, and the
testing phase is approximately 30% to 40% complete.
 
     The Company's year 2000 inventory of potentially affected items is
segregated into four categories: business applications (developed software,
customized extensions to purchased software and system interfaces), tools and
platforms (purchased commercial products, both hardware and software),
intelligent devices (manufacturing, laboratory, office, and facilities
equipment), and external business partners (suppliers, customers, and other
service providers). Business applications and tools and platforms are considered
information technology ("IT") systems while intelligent devices and external
business partners are considered non-IT systems.
 
     Concerning IT systems, two of the Company's businesses will replace most of
their existing applications with a year 2000 compliant version of new enterprise
resource planning ("ERP") software. Those legacy systems for these businesses
that will not be replaced by the ERP system will either be made year 2000
compliant or replaced. Two businesses are in the process of "repairing" (i.e.,
making year 2000 compliant) their existing core business systems and will
replace some portions of their software with year 2000 compliant software. The
remaining businesses have upgraded their core business applications to a year
2000 compliant software version and are in the process of testing these
applications for year 2000 compliancy.
 
     With respect to non-IT systems, the Company has dedicated resources to
assist its businesses with identifying potentially affected intelligent devices
and is using an outside firm that has a proprietary year 2000 compliance status
database to assist in the compliance research for these devices. Determination
of compliance status, remediation, and testing of these devices may be more
difficult than IT systems, as some of the manufacturers of potentially affected
equipment may no longer be in business.
 
     The external business partners category primarily includes the process of
identifying and prioritizing critical suppliers and customers and communicating
with them about their plans and progress in addressing the year 2000 problem.
The Company has established a questionnaire to be used by the businesses for
obtaining this information from key business partners. To date, the Company is
not aware of any problems that would materially impact results of operations,
liquidity, or capital resources. However, the Company has no means of insuring
that these parties will be year 2000 ready and the inability of these parties to
successfully complete their year 2000 compliance program could impact the
Company. For key business partners, the
 
                                        8
<PAGE>   11
 
initial assessments are evaluated and, as deemed necessary, follow-up
assessments are made. We expect this process to be ongoing throughout 1999.
 
     The Company is in the process of developing detailed contingency and
business continuation plans for each business to address potential year 2000
exposures.
 
  Costs
 
     The Company utilizes both internal and external resources to repair or
replace, test, and implement the software and operating equipment for year 2000
modifications. The total cost of the year 2000 project is estimated at between
$6 and $7 million and is being funded through operating cash flows. To date, the
Company has incurred approximately $2.5 million (approximately 60% expensed and
40% capitalized) related to all phases of the year 2000 project. The remaining
project costs are attributable to either repair or replacement of equipment,
hardware, and software and will be expensed as incurred or capitalized, as
appropriate.
 
  Risks
 
     The failure to remediate a material year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations, including the ability to produce or deliver products to customers.
Such failures could materially or adversely affect the Company's results of
operations, liquidity, and financial condition. Due to the general uncertainty
inherent in the year 2000 problem, the Company is unable to determine with
certainty at this time whether the consequences of year 2000 failures will have
a material impact on the Company. The Company's year 2000 plan is expected to
significantly reduce the Company's level of uncertainty about the year 2000
problem. The Company believes that by executing its year 2000 plan in a timely
manner, the possibility of significant interruptions of normal operations should
be reduced.
 
     The Company plans to complete the year 2000 project are based on
management's best estimates, which were derived utilizing numerous assumptions
of future events including, but not limited to, the continued availability of
certain resources and other factors. Estimates of the status of completion and
the expected completion dates are based on tasks completed to date compared to
all required tasks. However, there can be no guarantee that expected completion
dates will be met, and actual results could differ materially from those
forecasted. Specific factors that might cause such material differences include,
but are not limited to, the availability and cost of personnel trained in
certain areas, the ability to locate and correct all relevant equipment, devices
and computer codes, and similar uncertainties.
 
ITEM 7A  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
     Dexter is exposed to market risk related to changes in foreign currency
exchange rates, interest rates and commodity prices, and selectively uses
financial instruments to manage these risks. The Company does not enter into
financial instruments for speculation or trading purposes. A discussion of the
Company's accounting policies for derivative financial instruments is included
in the Long-term Debt footnote on pages 36 and 37, and the Currency Exchange
Effects footnote on page 33 of the 1998 Annual Report which are incorporated
herein by reference.
 
     The Company has two interest rate exchange agreements with a financial
institution to limit exposure to interest rate volatility. Additionally, the
Company enters into forward foreign currency contracts to mitigate the risks of
doing business in foreign currencies. The Company hedges currency exposures of
firm commitments and specific assets and liabilities denominated in
non-functional currencies to protect against the possibility of diminished cash
flow and adverse impact on earnings. The Company's currency exposures vary, but
are primarily concentrated in the German Mark, Swiss Franc, British Pound
Sterling, Swedish Krona and Japanese Yen. Selective translation exposures are
hedged using foreign currency-denominated debt. The Company's exposure to
commodity price changes relates to certain manufacturing operations that utilize
certain commodities as raw materials. The Company manages its exposure to
changes in those prices
 
                                        9
<PAGE>   12
 
primarily through its procurement and sales practices. At December 31, 1998, the
Company had no financial instruments outstanding as hedges of commodity price
risk.
 
     These financial exposures are monitored and managed by Dexter as an
integral part of Dexter's overall risk management program, which recognizes the
unpredictability of financial markets and seeks to reduce the potentially
adverse effect on Dexter's results. The value of market risk sensitive financial
instruments is subject to change as a result of movement in market rates and
prices. Sensitivity analysis is one technique used to evaluate the impact of
such possible movements on the valuation of these instruments. Based on a
hypothetical ten-percent change in the value of business unit functional
currencies at December 31, 1998, the Company estimates that the fair market
value of the forward foreign currency contracts would have changed by $1.4
million. Further, the impact on Dexter's future cash flow related to foreign
currency-denominated debt would be $3.5 million. In addition, based on a
hypothetical one percentage point decrease in interest rates at December 31,
1998, the Company estimates that the fair market value of the interest rate
exchange agreements would have decreased by $1.2 million. Changes in the fair
market value of the forward foreign currency contracts and interest rate
exchange agreements are substantially offset by changes in the fair value of the
underlying hedged positions. Further, based on a hypothetical one percentage
point decrease in interest rates at December 31, 1998, the Company estimates
that the fair market value of its fixed-rate long-term debt would have increased
by $9 million, which includes the effect of interest rate exchange agreements. A
hypothetical one percentage point increase in interest rates related to floating
rate debt at December 31, 1998 would decrease future pretax earnings and cash
flow by $2.6 million annually.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Dexter Corporation
 
In our opinion, the consolidated financial statements of Dexter Corporation
listed in the index on page F-1 of this Form 10-K, present fairly, in all
material respects, the consolidated financial position of Dexter Corporation at
December 31, 1998, 1997, and 1996, and the consolidated results of its
operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedule listed in the accompanying index presents fairly,
in all material respects, the information set forth therein when read in
conjunction with the related consolidated financial statements. These financial
statements are the responsibility of Dexter Corporation's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                                  Miscellaneous

7.01     Unfunded Benefits. Any benefits payable under the Plan shall be paid by
         the Corporation out of its general assets and shall not be funded in
         any manner, provided, however, that in order to assure payment under
         the Plan, the

                                                           Exhibit 10F continued

         Corporation may establish one or more trusts; and further, that any
         assets transferred to a trust pursuant to this sentence would remain
         subject to the claims of the general creditors of the Corporation.

7.02     Liability of the Corporation and Board. The Corporation shall not be
         required to segregate assets to provide payments under the Plan
         although it may do so. Neither the Corporation nor the Board shall be
         deemed to be a Trustee of any amounts to be paid under the Plan.

7.03     Assignment of Benefits. No benefit payable under the Plan shall be
         subject in any manner to alienation, sale, transfer, assignment,
         anticipation, pledge, encumbrance, or charge; any attempt to
         anticipate, alienate, sell, transfer, assign, pledge, encumber, or
         charge such benefits shall be void; and no such benefit or interest
         therein shall be liable for or subject to the debts, contracts,
         liabilities or torts of any Participant or Beneficiary. If any
         Participant or Beneficiary becomes bankrupt or attempts to anticipate,
         alienate, sell, transfer, assign, pledge, encumber, or charge any
         benefit under the Plan, the Plan Administrator may direct that such
         benefit be terminated and that all future payments to which such person
         otherwise would be entitled be held and applied for the benefit of such
         person, his or her children or other dependents, or any of them, in
         such manner and in such proportions as the Plan Administrator may deem
         proper.

7.04     Incapacity of Employee or Beneficiary. If the Corporation determines
         that any person to whom any payment is payable under the Plan is unable
         to care for his or her affairs or is a minor and a legal representative
         has not been appointed for such person, the Corporation may (but shall
         not be required to) direct that any benefits payable hereunder shall be
         paid to a spouse, child, parent, or other blood relative of such
         person, or to anyone found by the Corporation to have properly incurred
         expense for the support and maintenance of such Participant or
         Beneficiary, so long as such payment is permitted under applicable law
         and discharges completely all liability of the Corporation under the
         Plan.

7.05     Withholding. The Corporation shall have the right to deduct from the
         amount of any payment to a Participant (or to a Beneficiary or to the
         executors, administrators, legatees, or distributees of the
         Participant's or Beneficiary's estate) any Federal, state or local
         taxes required by law to be withheld from such amount.

7.06     No Right to Employment. Nothing in the Plan (including the designation
         of an individual as a Participant) shall be construed as giving a
         Participant any right to be retained in the employ of the Corporation
         or any right to any payment except for any benefits that may be due
         under the terms of the Plan. The Corporation expressly reserves the
         right to dismiss any Participant at any time without regard to the
         effect that such dismissal may have with respect to such benefits.

7.07     Necessary Information. A Participant eligible to receive benefits under
         the Plan shall furnish to the Plan Administrator any information or
         evidence requested by the Plan Administrator and reasonably required
         for the proper administration of the Plan. Failure on the part of any
         person to comply with any such request within a reasonable period of
         time shall be sufficient grounds for delay in payment of any benefits
         that may be due under the Plan until such information or evidence is
         received by the Plan Administrator. If any person claiming benefits
         under the Plan makes a false statement which is material to the claim
         for benefits, the Plan Administrator may offset against future payments
         any amount paid to such person to which he or she was not entitled
         under the provision of the Plan.

7.08     Binding Effect. The provisions of the Plan shall be binding upon and
         inure to the benefit of the Corporation, its successors and assigns and
         to the Participant, his/her heirs, executors, administrators and legal
         representative.

7.09     Governing Law. The provisions of the Plan shall be construed in
         accordance with and governed by the laws of the State of Connecticut.

                                    EXHIBIT B


1.01     Scope

         This Exhibit B sets forth the method for calculating the Annual Benefit
         payable to Participants in this Plan under Section 4.01.

1.02     Calculation of Annual Benefit

         Each Participant in this Plan who is an active participant in ESPRIT,
         MERIT or the SAVINGS PLAN shall receive the Annual Benefit set forth in
         subsection (a) of this Section 1.02. Notwithstanding any other
         provision of this Plan to the contrary, each Participant in this Plan
         who is an active participant in the PENSION PLAN shall receive the
         Annual Benefit set forth in Subsection (b) of this Section 1.02.

         (a)      The Annual Benefit for a given Plan Year shall be equal to the
                  Adjusted Covered Plan Contribution (as defined below) less the
                  amounts of the contributions and forfeitures actually credited
                  to the Participant's accounts under the applicable Covered
                  Plan for such Plan Year. For the purposes hereof, the term
                  "Adjusted Covered Plan Contribution" shall mean the sum of the
                  total contributions and forfeitures which could have been
                  credited to such Participant under the applicable Covered Plan
                  for a given Plan Year determined (i) before applying any
                  provision of such Covered Plan that would reduce the amount of
                  such contributions or forfeitures because of the limitations
                  imposed by Section 415 of the Code or because of the
                  limitations imposed by Section 401(a) (17) of the Code on the
                  amount of the Participant's compensation that may be taken
                  into account for the Plan Year, (ii) by treating the amount of
                  the Participant's voluntary after-tax contributions and
                  elective deferrals for the Plan Year (if any) as if such
                  amount were zero, (iii) by treating the amount of any
                  executive incentive compensation payments accrued but not
                  received by the Participant during such Plan Year under the
                  Corporation's Senior Management Executive Incentive Plan as if
                  such amount were paid during such Plan Year; and (iv) by
                  treating the amount of any executive incentive compensation
                  payments received by the Participant during such Plan Year
                  under the Corporation's Senior Management Executive Incentive
                  Plan that were accrued and payable in respect of a prior Plan
                  Year as if such amount were zero.

         (b)      The Annual Benefit for a given Plan Year shall be an amount
                  equal to four percent (4%) multiplied by the Participant's
                  Compensation for the Plan Year, as such term is defined in
                  Section 1.11 of the PENSION PLAN, without regard to Section
                  401(a)(17) of the Code, less the annual Compensation Limit
                  then in effect under Section 401(a)(17) of the Code for the
                  Plan Year.

                               DEXTER CORPORATION

             AMENDMENT OF THE 1994 STOCK PLAN FOR OUTSIDE DIRECTORS


1. This amendment to the 1994 Stock Plan for Outside Directors (the Plan) of
Dexter Corporation (the Company) is made pursuant to Article X of the Plan and
shall be effective as of February 26, 1999.


2. Section 5.01 of the Plan is amended to read as follows:

         5.01. Amount of grants. Beginning with the Fiscal Year 1994 and
continuing for all Fiscal Years until the Plan expires pursuant to Section 8.02
or is earlier terminated pursuant to Article X, and subject to Section 5.02, a
grant of Directors Shares shall be made to each person who served as an Outside
Director during all or part of such Fiscal Year as follows:

                  (i) each person who has served as an Outside Director during
         the entire Fiscal Year shall be granted 300 Directors Shares; and

                  (ii) each person who has served as an Outside Director during
         only a portion of the Fiscal Year shall be granted the number of
         Directors Shares determined by multiplying 300 by the Pro Ration
         Fraction, provided, however, that any fractional shares resulting from
         such multiplication shall not be awarded, and the Outside Director
         shall instead be paid an amount in cash equal to such fractional amount
         times the Fair Market Value of one share of Common Stock determined as
         of the last day of the relevant Fiscal Year.

3. In all other respects, the Plan as hereby amended is ratified and confirmed.

         IN WITNESS WHEREOF, the Company has executed this amendment as of

Compensation & Organization Committee.

October 21, 1998

To:           R. Barry Gettins

From:         K. Grahame Walker

Subject:      Your Retirement Status

The purpose of this memorandum is to confirm our earlier discussions and
finalize the details relative to your retirement from Dexter Corporation. As
several of the particular elements of your retirement benefits require formal
approval by the Compensation and Organization Committee of the Dexter
Corporation's Board of Directors, those elements are expressed as contingent
upon the Committee's approval. Nevertheless, they represent what I am prepared
to go forward with to the Committee subject to your agreement and understanding
and accompanying release.

         Date of Retirement: December 31, 1998

         Executive Supplemental Retirement Plan (SRP): Subject to the approval
of the Compensation and Organization Committee of the Board, you will be
eligible to receive a Special Early Retirement as provided for in Section 2.04
(d) of the Plan. The estimated benefits have been prepared by
PriceWaterhouseCoopers LLP and provided to you already. A final calculation will
be prepared and provided upon your retirement.

         Retiree Medical Insurance: You will become eligible to participate in
the Retiree Medical Program provided by the Corporation. Under this program, you
will be able to continue your current coverage until you reach age 65. Given
your length of service, Dexter Corporation will contribute 75% of the cost of
your retiree medical coverage for 1999. Beginning in the year 2000, the cost
sharing formula will include a cap on the annual increase in Dexter's
contribution.

         Long Term Incentive Plans:

                  Restricted Stock Grants: Subject to the approval of the
Compensation and Organization Committee of the Board, all remaining restrictions
with respect to the restricted stock grants you have received shall expire.
Specifically, the time-lapse restrictions on Grants # 1-6 will expire upon your
retirement and any remaining performance target restrictions will expire at such
time as the achievement of the relevant performance targets is determined.

                  Non-Qualified Stock Options: Subject to the approval of the
Compensation and Organization Committee of the Board, all remaining stock
options that you have been awarded will become fully vested and exercisable on
January 4, 1999. In addition, approval will be sought to extend the period of
exercise for all of your options through December 31, 2000.

         Company Car: You will retain the use of your company-provided car
through June 30, 1999. You may elect to purchase the vehicle at its stated fair
market value at the end of this extension period.

         Executive Incentive Compensation: You will be eligible to receive any
applicable EIC payment for the performance year 1998 as determined by the
provisions of the Plan. Any earned payment shall be made at the end of the
year-end audit sign-off in February 1999.

         ESPRIT and Retirement Equalization: ESPRIT and Retirement Equalization
contributions will be applied to all earnings for 1998 in accordance with the
respective plans.

Please indicate your understanding and acceptance of the terms of your
retirement from Dexter Corporation. As they represent a significant additional
benefit to you, they are contingent upon your signature on a standard release
and waiver that is attached to this agreement.

MANAGEMENT STATEMENT

The management of Dexter Corporation has prepared the financial statements and
review contained on pages 14 through 39 in conformity with generally accepted
accounting principles. Dexter's management is responsible for the integrity and
objectivity of this annual report, including the financial statements, charts,
tables and other supplementary information. The financial statements and review
are presented on the accrual basis of accounting and, accordingly, include some
amounts based on judgment. Information included on these pages is an integral
part of the statement of financial position and related statements of income,
cash flows and changes in shareholders' equity which have been audited by
PricewaterhouseCoopers LLP. 

Dexter has a clearly stated business ethics policy and code of conduct that
require employees to maintain high standards in their conduct of company
affairs. The company's accounting and control systems are designed to provide
reasonable assurance that financial records accurately reflect the transactions
of Dexter Corporation and that the company's assets are protected from
unauthorized use and preserved in accordance with established policies and
procedures, as implemented by qualified personnel. We modify and improve our
systems in response to changes in business conditions and operations, the advice
of independent certified public accountants, and the recommendations of our own
internal auditors and other independent experts on procedures and controls.
There are no known significant accounting control weaknesses.

PricewaterhouseCoopers LLP, independent certified public accountants, is engaged
to perform quarterly reviews and annual audits. Their audits are conducted in
accordance with generally accepted auditing standards which include
consideration of the company's internal controls. The Audit Committee of the
Board of Directors, made up entirely of outside directors, meets both separately
and jointly with the independent certified public accountants, internal auditors
and management to review accounting policies, adequacy of controls, quality of
financial reporting, and the scope and results of audits. Both the internal
auditors and the independent accountants have free and direct access to the
Audit Committee without the presence of management.

A company with a good reputation is not only a good supplier, customer and
citizen, but a good employer. Dexter has enjoyed a reputation based on integrity
for over two centuries. We are all the guardians of that reputation, and that
responsibility requires vigilance.

REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Shareholders of Dexter Corporation:

In our opinion, the accompanying consolidated statement of financial position
and the related consolidated statements of income, cash flows, and changes in
shareholders' equity, contained on pages 14 through 39, present fairly, in all
material respects, the consolidated financial position of Dexter Corporation at
December 31, 1998, 1997, and 1996, and the consolidated results of its
operations and its cash flows for the years then ended, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of Dexter Corporation's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

*The second quarter pretax income included a $2.7 million gain on divestiture of
product lines, including $2.6 million due to the receipt of proceeds from a note
related to the sale of LTI's molecular diagnostic product line in 1990. The net
effect of the sale of the company's acoustic materials business and a small
powder coatings business in the second quarter had a slightly positive impact on
earnings.

ANALYSIS OF FINANCIAL CONDITION AND OPERATIONS

PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the
accounts of all majority owned subsidiaries. All consolidated subsidiaries are
wholly owned except Life Technologies, Inc. ("LTI") and a few other
subsidiaries, primarily outside the United States, in which aggregate minority
interests are not significant. Intercompany accounts, transactions and profits
have been eliminated in the consolidated financial statements. Companies owned
20% to 50% are accounted for by the equity method. The preparation of financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting periods. Actual results
could differ from those estimates. Certain amounts for prior years have been
reclassified to conform to and be consistent with the 1998 presentation.

FORWARD-LOOKING STATEMENTS Some of the matters discussed in this 1998 Annual
Report are forward-looking statements that involve risks and uncertainties.
These forward-looking statements include, but are not limited to, statements
about (i) meeting the company's published financial goals, (ii) future growth in
the company's revenues, earnings and dividends, and (iii) improvements in the
markets served by the company. Actual results could differ materially from such
forward-looking statements because of, among other things, the following
factors: unit volume growth substantially different from the company's targeted
range; the impact of competitive products and pricing; changes in the prices of
raw materials; fluctuations in foreign currency rates; changes in laws and
regulations; risks pertaining to the Year 2000 issue, and other risks identified
below in the section entitled "Events, Trends and Vulnerabilities."

EVENTS, TRENDS AND VULNERABILITIES Dexter is subject to a multitude of events
and trends that influence its business prospects, profitability, and liquidity.
Many of these events and trends are outside the control of the company. However,
the consequent effects need to be managed as part of the ongoing business
environment.

During 1998, selling prices and raw material costs were relatively stable.
Although aggressive efforts to raise prices and gain full value for our product
offerings occurred in 1998, excess worldwide capacity made it increasingly
difficult to obtain selling price increases. Most businesses, including LTI,
experienced overall selling price decreases in 1998. Most businesses also
experienced overall decreases in raw material costs, but these decreases did not
fully offset the lower selling prices. We expect raw material costs to remain
relatively stable in the short term. However, any substantial increases in
future demand for the materials the company purchases, provided no additional
production capacity is built, will inevitably support higher levels of cost to
Dexter. LTI is subject to volatility in the cost of fetal bovine serum, which
stems from a fundamental limit of supply. Further, for less critical
applications, additional competition can be expected consequent to the
development of substitute products for cell culture which do not depend on
traditional raw materials.

Unit volume growth of sales of 2% supported gross margin expansion in 1998. To
the extent that the unit volume growth rate decreases in the future as a result
of some weakness in domestic or international economies, revenue and earnings
growth may be negatively impacted. The severe Asian economic downturn
experienced in 1998 had an unfavorable impact on the electronics industry as a
whole and resulted in significantly lower sales and lower margins in our
electronic materials business. It is expected that the Asian economic
environment will improve moderately in 1999. However, further decreases in
demand for the company's products or the inability of customers to remain viable
in the region may reduce the growth potential in this area over the short- to
medium-term. The consequences of domestic interest rate changes and tax policy
may also influence total demand in our served markets.

Since approximately 50% of Dexter's profits are derived from products sold
outside the United States, any weakening of international currencies against the
U.S. dollar could have a negative effect on the company's results. Additionally,
the volatility of several Asian and Latin American currencies could create
exposures and losses for the company. Geographical expansion will continue to
provide opportunities and challenges as the company endeavors to create
profitable growth in developing countries.

There will continue to be costs incurred by the need to respond to heightened
regulatory pressures. Such costs may be significant in areas of environmental,
health, social and administrative regulation. Heightened worldwide environmental
concerns have led to greater capital requirements and increased operating
expenses. While the company, based on known facts and circumstances, has
provided substantial environmental reserves as shown at year end in the
Statement of Financial Position, the ultimate cost of compliance and remediation
cannot be ascertained and, therefore, there is no assurance that such reserves
will prove to be adequate over time.

National and local deficits, as well as ongoing economic issues in several parts
of the world, may dictate the need for greater tax receipts or significant
reductions in government spending. Future increases in taxes by countries,
states and localities in which we operate may be the ultimate outcome of this
imbalance. Lower government spending may adversely affect LTI by reducing the
overall availability of government funding for life science research.

Other areas which will have an important impact on the future of the company
will be the increasing rate of technological change, a continued universal move
toward higher quality products, shortened product life cycles and further
globalization of our customers and competitors. Technology is the lifeblood of
the corporation. In order to remain competitive we must, successfully and
rapidly, introduce new products that not only replace our current products but
also those of our competitors; otherwise, we are potentially exposed to reduced
margins and loss of business.

The general aging of the U.S. population creates challenges with respect to the
availability of employees as well as amplifying trends in increased health care
costs. Dexter's ability to hire and retain a qualified workforce around the
world will be fundamental to our growth and success. Increased training and
developmental needs will require additional resources to maintain and improve
our overall competencies.

The company recognizes potential system failures arising from processing the
Year 2000 date as a known risk. The company is addressing this risk by executing
its Year 2000 Project Plan, which requires, among other things, that systems and
equipment found not to be Year 2000 compliant be repaired or replaced. The
company is currently working with its customers and suppliers to identify
external issues associated with the Year 2000 and their planned remedies. There
can be no assurance, however, that the company will be able to identify and
correct all aspects of Year 2000 problems that affect the company's business.
The company believes that the cost associated with becoming Year 2000 compliant
will not have a material negative effect on its results. See item 7,
Management's Discussion and Analysis of Financial Condition and Results of
Operations, in the 1998 Form 10-K for further information regarding the
company's Year 2000 project status.

The complexities of ever-changing worldwide events and trends including the
international political environment, the global marketplace, and the advancement
of technology generate numerous vulnerabilities and challenges. The company
believes that it will successfully face these challenges with continued
innovation and increased productivity.

ACQUISITIONS AND DIVESTITURES On July 7, 1998, Dexter announced two major
strategic initiatives aimed at better positioning the company to achieve its
long-term growth objectives. These initiatives included the proposal to acquire
the remaining 48% equity in LTI that it did not own and to sell Dexter's
Packaging Coatings business, including Dexter SAS, its French coatings
subsidiary.

As a result, Dexter made a proposal to the LTI Board of Directors to acquire
approximately 11.3 million shares of LTI common stock it did not own. On
November 2, 1998, Dexter commenced a tender offer for such shares and on
December 22, 1998, Dexter completed its tender offer. Approximately 5.5 million
shares representing approximately 22% of all issued and outstanding LTI shares
were tendered and purchased by Dexter for a total of $222.1 million including
transaction costs. As a result of the acquisition of these shares, Dexter owns
an aggregate of 17.8 million shares or approximately 71% of the total number of
issued and outstanding shares.

The acquisition was accounted for as a purchase, and accordingly, the purchase
price has been allocated to the identified tangible and intangible assets based
upon Dexter's proportionate interest in the estimated fair market value of those
assets. This allocation resulted in a write-up of tangible assets of
approximately $3.2 million. Identifiable intangible assets were valued at
approximately $91.5 million, consisting of trademarks and current technology,
including patented technology. These intangible assets will be amortized over
their estimated useful life of 30 years. In addition, deferred tax liabilities
of approximately $33.1 million were recognized relative to the assets referenced
above.

The value of in-process research and development for which technical feasibility
had not yet been achieved was approximately $24.5 million and was charged
against earnings in the fourth quarter of 1998. This transaction resulted in
excess cost over net assets acquired (goodwill) of approximately $63.4 million
which will be amortized over the estimated useful life of 30 years.

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, and
January 1, 1997, respectively.

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 dates indicated, or
which may result in the future.

On August 21, 1998, Dexter 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 estimated total proceeds of $225 million.

In January 1999, Dexter divested its 40% interest in Akzo Dexter Aerospace
Finishes VoF, a joint venture between Dexter Corporation and Akzo Nobel NV, to
Akzo Nobel NV for approximately book value. As a result of this divestiture,
Dexter announced its intention to expand its existing network as a worldwide
supplier of aerospace coatings technologies, continuing to operate from its
OEM-approved manufacturing facilities in Bassano, Italy and Waukegan, Illinois.

LIQUIDITY The company's liquidity is strong and ample lines of credit are
available to the company and its subsidiaries. The current ratio (current assets
divided by current liabilities) is 2.1 to 1, and the quick ratio (cash,
short-term securities and accounts receivable divided by current liabilities) is
1.3 to 1. As shown in the Statement of Cash Flows, cash provided from operations
of $98 million and financing activities of $188.8 million exceeded cash needed
for investments of $245.4 million, thereby increasing year-end cash and
short-term securities by $41.4 million. Investment activity during 1998 included
capital expenditures of $54.2 million in addition to cash outflows for
acquisitions of $218 million, primarily related to the acquisition of an
additional 22% of LTI. These investments were funded primarily by new long-term
debt of $246 million in 1998. The LTI acquisition is described in the
acquisitions and divestitures footnote on this page. Excluding LTI, the current
ratio is 1.6 to 1 and the quick ratio is 1 to 1. Excluding LTI, cash provided
from financing activities of $192.1 million and operations of $55.9 million
exceeded cash needed for investments of $246.7 million, resulting in an increase
in cash and short-term securities of $1.3 million in 1998.

The company plans to meet its future working capital and capital expenditure
needs with funds provided from operations, the reduction of short-term
securities and, as needed, short-term and long-term borrowings. The company
plans to use the proceeds from the sale of its Packaging Coatings business to
repay long-term debt.

ANALYSIS OF OPERATIONS


1998 COMPARED WITH 1997

REVENUES: Net sales were a record $1.17 billion in 1998, an increase of $21
million, or 2%, over 1997 sales of $1.15 billion. The 2% increase in sales was
due to unit volume increases of 2% and a 2% increase due to the effect of
acquisitions, partially offset by selling price decreases averaging 1% and a 1%
decrease due to the effect of lower currency translation rates on international
sales. 

Equity in net income of affiliates decreased $1.1 million to $3.3 million in
1998. This decrease was primarily due to no 1998 equity earnings from D & S
Plastics International, which was divested effective April 1, 1997.

EXPENSES: Cost of sales decreased as a percentage of sales in 1998, thereby
increasing consolidated gross margins by .6 percentage points to 36.5% of sales
from 35.9% in 1997. Gross margin, excluding Life Technologies, Inc. ("LTI"),
increased .3 percentage points, primarily due to productivity improvements and
cost containment activities. The remaining favorable impact in gross margin was
primarily attributable to increased sales volume at LTI. 

Marketing and administrative expenses increased $8.5 million, or 4%, in 1998
compared with 1997 principally due to increased marketing and administrative
expenses at LTI. Research and development expense increased $2.6 million, or 5%,
primarily due to costs associated with acquired Dexter businesses in the fourth
quarter of 1997 and increased research and development expense in the nonwovens
segment and at LTI. 

Interest expense decreased $2 million, or 10%, in 1998 compared with 1997
primarily due to lower average long-term borrowings in 1998. The company does
not capitalize interest on facilities under construction. If interest had been
capitalized, there would have been no impact on earnings per share in 1998 and
earnings per share would have increased by $.02 per share in 1997. 

Pretax income included a charge of $24.5 million, which represents the write-off
of acquired in-process research and development costs arising from the
acquisition of an additional 22% of LTI in December 1998 and $5.3 million of
transaction costs incurred by LTI related to Dexter's increased ownership. There
were no such charges in 1997. 

INCOME TAXES: In 1998, the effective tax rate was 35% from operations, excluding
one-time charges. Due to the nondeductibility of acquired in-process research
and development costs and certain transaction costs at LTI, the consolidated
effective tax rate in 1998 was 46.4% compared with 36% in 1997.

MINORITY INTEREST: Income attributed to minority interest shareholders remained
largely unchanged in 1998 compared with 1997 as increases in LTI income from
operations were offset by $5.3 million of transaction costs.

NET INCOME: Net income from operations, excluding one-time charges, for the year
1998 was $58.4 million, or $2.50 per share on a diluted basis. This represents a
4% increase in earnings and diluted earnings per share from operations compared
with results for 1997 of $56.4 million, or $2.41 per share diluted. Including
the acquired in-process research and development costs and transaction costs
which totaled $29.8 million, or $1.15 per share diluted, 1998 net income was
$31.7 million, or $1.35 per share diluted, compared with $2.41 per share diluted
in 1997.

1997 COMPARED WITH 1996

REVENUES: Net sales were $1.15 billion in 1997, an increase of $46.9 million, or
4% over 1996 sales. The 4% increase in sales was due to unit volume increases of
7% partially offset by a 3% decrease due to the effect of lower translation
rates on international sales. Selling prices remained largely unchanged versus
1996. The net effect of acquisitions and divestitures in 1996 and 1997 accounted
for an increase in sales of $3.7 million in 1997. 

Equity in net income of affiliates decreased $0.3 million to $4.5 million in
1997. This decrease was primarily due to lower equity earnings resulting from
the divestiture of D & S Plastics International, which was effective April 1,
1997. 

EXPENSES: Cost of sales decreased as a percentage of sales in 1997, thereby
increasing consolidated gross margins by 1.4 percentage points to 35.9% of sales
from 34.5% in 1996. Gross margin, excluding LTI, increased 1.2 percentage
points, primarily due to strong volume increases, favorable product mix and
productivity improvements. The remaining improvement was attributable to LTI.

Marketing and administrative expenses increased $14.6 million, or 7%, in 1997
compared to 1996, principally due to costs associated with acquired Dexter
businesses in 1997 and increased marketing and administrative expenses at LTI.
Research and development expenses increased $2.5 million, or 5%, primarily due
to increases at LTI. 

Interest expense decreased $0.3 million, or 2%, in 1997 compared with 1996,
primarily due to lower average long-term borrowings throughout the year. If
interest had been capitalized, earnings per share would have increased by $.02
per share in 1997 and there would have been no impact on earnings per share in
1996. 

In 1996, there was a gain on divestiture of product lines of $2.7 million. This
included $2.6 million due to the receipt of proceeds from a note related to the
sale of LTI's molecular diagnostic product line in 1990 and the net effect of
the sale of the company's acoustic materials business and a small powder
coatings business in 1996. 

INCOME TAXES: The effective tax rate was 36% in 1997 compared with 35.5% in
1996.

MINORITY INTEREST: Income attributed to minority interest shareholders remained
largely unchanged in 1997 compared with 1996. Higher minority interest expense
attributed to increased profits at LTI in 1997 was principally offset by lower
minority interest expense resulting from other majority owned entities.

NET INCOME: Net income for the year 1997 was $56.4 million, or $2.41 per share
on a diluted basis. This represents an 18% increase in net income and a 21%
increase in diluted earnings per share, compared with results for 1996 of $47.7
million, or $1.99 per share diluted, excluding the net gain from the 1996
disposal of product lines. Including the $.04 per share gain on divested product
lines, the 1996 earnings were $48.7 million, or $2.03 per share diluted.
Comparing the total amounts for 1996, the increases for 1997 in earnings and
diluted earnings per share were 16% and 19%, respectively.

1996 COMPARED WITH 1995

REVENUES: Net sales were $1.10 billion in 1996, an increase of $11.3 million, or
1%, over 1995 sales. The 1% increase in sales was due to unit volume increases
of 3%, selling price increases averaging 1%, a 2% decrease due to the net effect
of acquisitions and divestitures, and a 1% decrease due to the effect of lower
translation rates on international sales.

Equity in net income of affiliates increased $3.5 million to $4.8 million in
1996. This increase was due to the increase in the results of D & S Plastics
International.

EXPENSES: Cost of sales decreased as a percentage of sales in 1996, thereby
increasing consolidated gross margin by 2.7 percentage points to 34.5% of sales
from 31.8% in 1995. Gross margin, excluding LTI, increased 1.6 percentage
points, principally resulting from the favorable impact of selling price
increases and raw material cost decreases. The remaining improvement was
attributable to an increased gross margin on sales of fetal bovine serum and
higher gross margin on sales of product in Japan by LTI.

Marketing and administrative expenses increased $17.1 million, or 8%, in 1996
compared with 1995, principally due to increased marketing and administrative
expenses at LTI, which included the consolidation of results from the third
quarter 1995 acquisition of a controlling interest in their Japanese subsidiary.
Marketing and administrative expenses, excluding LTI, increased 3% in 1996
compared with 1995, due mainly to higher selling and marketing expenses.
Research and development expenses increased $2.1 million, or 4%, due to
increases at LTI.

Interest expense decreased $0.4 million, or 2%, in 1996 compared with 1995,
primarily due to lower average long-term borrowing throughout the year. If
interest had been capitalized, there would have been no impact on earnings per
share in 1996 or 1995.

In 1996, there was a gain on divestiture of product lines of $2.7 million. This
gain included $2.6 million due to the receipt of proceeds from a note related to
the sale of LTI's molecular diagnostic product line in 1990 and the net effect
of the sale of the company's acoustic materials business and a small powder
coatings business in 1996.

INCOME TAXES: The effective tax rate was 35.5% in 1996 and 1995.

MINORITY INTERESTS: Income attributed to minority interest shareholders
increased 34% from 1995 due primarily to increased profits at LTI.

NET INCOME: Net income for the year 1996 was $47.7 million, or $1.99 per share
diluted, excluding the $ .04 per share net gain from the second quarter 1996
disposal of product lines. This represents an 18% increase in net income and a
20% increase in diluted earnings per share, compared with results for 1995 of
$40.6 million, or $1.66 per share diluted. Total earnings for 1996, including
the gain on divested product lines, increased 20% to $48.7 million while diluted
earnings per share gained 22% to $2.03 per share diluted. The 1996 earnings
include the favorable effect of selling price increases and lower raw material
costs of approximately $.51 per share compared with 1995 which was somewhat
offset by currency exchange rates, product mix, and increased marketing and
administrative expenses.

TAXES: The effective income tax rate was 46.4% in 1998, 36% in 1997, and 35.5% 
in 1996. The tax rate is currently expected to approximate 36% in 1999. The
income tax rate differs from the statutory U.S. federal income tax rate as shown
below:

Pretax income from international operations amounted to $57.3 million in 1998,
$54.6 million in 1997 and $59.6 million in 1996. U.S. and international income
and withholding taxes have not been provided on temporary differences related to
investments in foreign subsidiaries. These differences principally include
unremitted earnings of approximately $177 million, differences between the
financial reporting amounts and tax bases of investments in foreign subsidiaries
and cumulative translation adjustments. The investment in these subsidiaries is
considered to be permanent in nature. It is impracticable to estimate the total
tax liability, if any, which these differences could cause should such
investments cease to be treated as permanently reinvested.

Valuation allowances of $1.3 million at December 31, 1998, $2.3 million at
December 31, 1997 and $3.6 million at December 31, 1996, reduced the deferred
tax asset attributable to foreign loss carryforwards to an amount that, based
upon all available information, is more likely than not to be realized. Reversal
of the valuation allowance is contingent upon the recognition of future taxable
income and capital gains in specific foreign countries or changes in
circumstances which cause the recognition of the benefits of the loss
carryforwards to become more likely than not. The decrease of $1 million in the
valuation allowance during 1998 was due principally to the utilization of
foreign loss carryforwards.

The components of deferred taxes at December 31, 1998, 1997 and 1996 are as

EARNINGS PER SHARE Earnings in 1998 of $1.35 per share represented a decrease of
44% in diluted earnings per share, compared with earnings of $2.41 per share in
1997. Excluding the net loss of $1.15 per share in 1998 due to transaction costs
and the write-off of acquired in-process research and development costs, 1998
earnings from operations were $2.50 per share diluted, an increase of 3.7%
compared with 1997.

Basic earnings per share in 1998 of $1.38 decreased 43.7% compared with $2.45
per share in 1997. Excluding the transaction costs and the write-off of acquired
in-process research and development costs incurred in 1998, basic earnings per
share from operations were $2.54, a 3.7% increase over 1997. Basic earnings per
share is calculated by dividing net income by the weighted average number of
shares of common stock outstanding during the year. The reconciliation between
basic earnings per share and diluted earnings per share is presented below:

</TABLE>

At December 31, 1998, 279,950 options were outstanding at a weighted average
exercise price of $41.42 that were not included in the computation of diluted
earnings per share because the exercise price of the options was greater than
the average market price of the company's common stock for the year. At December
31, 1997, 10,000 options were outstanding at an exercise price of $41.22, and at
December 31, 1996, 24,644 options were outstanding at an exercise price of
$29.06 that were not included in the computation of diluted earnings per share.

LIFE TECHNOLOGIES, INC.

On September 1, 1983, Dexter's GIBCO subsidiary merged with Bethesda Research
Laboratories, Inc. The resulting freestanding company was renamed Life
Technologies, Inc. (and hereinafter referred to as "LTI") and at December 31,
1998 was owned 71% by Dexter, with the remainder owned by the public. LTI's
common stock is currently available for quotation on the OTC Bulletin Board. In
1998, Dexter's proportionate ownership of LTI increased from 52% to 71%
subsequent to the completed tender offer for LTI common stock in December 1998.

LTI is reported in the life sciences segment, although LTI, as a publicly owned
company, issues its own annual report including audited financial statements.
These statements follow in condensed form.

Net sales of LTI increased $30.8 million, or 9%, in 1998. This improvement was
principally due to a $36.3 million, or 13%, increase in sales of products other
than fetal bovine serum ("FBS"), partially offset by lower currency translation
rates of $6.4 million.

Gross margin for 1998 was 53.6% of net sales compared with 53.9% in 1997.
Marketing and administrative expenses increased 10% to $118.6 million, or 32.8%
of net sales in 1998, compared with $108 million, or 32.6% of net sales in 1997.
Research and development expenses were $21.9 million in 1998, representing a 3%
increase compared with $21.3 million for 1997.

LIFE TECHNOLOGIES, INC. (continued)

Pretax income decreased $0.2 million to $51.1 million as a result of one-time
charges of $5.3 million related to Dexter's acquisition of additional shares of
LTI. Excluding these charges, pretax income increased 10% in 1998 compared with
1997. The effective tax rate was 37.5% in 1998 and 36% in 1997. Apart from the
nondeductable portion of the one-time charges, the effective income tax rate
would have been 34.5% in 1998. Net income decreased 3% to $31.3 million in 1998
from $32.2 million in 1997. Excluding one-time charges and the related income
tax effect, net income was 13% greater in 1998 than in 1997.

LTI declared quarterly dividends totaling $0.20 per share in 1998 and $0.18 per
share in 1997.

After the deduction of minority interests, LTI contributed $16.3 million to
Dexter's net income or $.69 per share on a diluted basis, in 1998, compared with
$17 million, or $.71 per share in 1997. Dexter's portion of LTI shareholders'
equity, per share of Dexter, increased to $8.56 at December 31, 1998, from $4.77
at year-end 1997, principally as a result of Dexter increasing its ownership to
71% in 1998.

At year-end 1998, LTI had $56 million in cash and short-term securities, $164.1
million in other current assets and $59.8 million of current liabilities.

In 1998, LTI spent $25.4 million on capital expenditures and was self-funding.
Capital expenditures in 1999 are expected to range between $30 and $35 million.
It is expected that LTI will continue to be self-funding in 1999.

SEGMENT DATA

In 1998, the company adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, which changes the way the company reports
information about its operating segments. The information provided for 1997 and
1996 has been restated in order to conform to the 1998 presentation. The company
is a global specialty materials supplier with three operating segments: life
sciences, nonwovens, and specialty polymers. The specialty polymers segment
includes businesses whose product offerings are primarily based on polymer
technologies serving the aerospace, electronics, food packaging, and industrial
assembly markets.

1998 COMPARED WITH 1997

Sales in the life sciences segment increased $30.8 million, or 9%, in 1998. A
12% increase in unit volume was somewhat offset by a 2% unfavorable effect of
currency translation rates and selling price decreases averaging 1%. Operating
income decreased $24.9 million, or 49%, in 1998 due to one-time charges for the
write-off of acquired in-process research and development costs of $24.5 million
recorded by Dexter and transaction costs of $5.3 million recorded by LTI related
to Dexter's increased ownership in LTI. Excluding these charges, operating
income increased $4.9 million due to the favorable impact on margins of the
higher sales volume.

Sales in the nonwovens segment decreased $2.2 million, or 1%, in 1998. A 1%
increase in unit volume was more than offset by price decreases averaging 1% and
a 1% unfavorable currency translation effect. Sales of medical and hygiene
products were stronger in 1998 compared with 1997, while sales of food packaging
materials and other specialty materials were weaker. Operating income decreased
$3.3 million, or 8%, in 1998 primarily due to lower gross margins resulting from
an unfavorable product mix, as well as, increased marketing and administrative
expenses and increased research and development expenses.

Sales in the specialty polymers segment decreased $7.5 million, or 1%, in 1998.
The effect of acquired businesses increased 1998 net sales by $19.8 million, or
4%. Net of acquired businesses, sales decreased 5% due to a 3% decrease in unit
volume, unfavorable currency translation effects of 1%, and selling price
decreases averaging 1%. Lower volume in the electronic materials business
related to the slowdown in the electronics market, especially in the Asian
sector, and lower sales of beer and beverage can coatings were partially offset
by higher sales in both the aerospace business and food and specialty can
coatings serving international markets. Operating income decreased $4.1 million,
or 8%, in 1998 primarily due to lower gross margins in the electronic materials
business resulting from sales volume decreases. This negative effect was
partially offset by higher operating income in the aerospace business resulting
from increased sales volume and continued productivity improvements.

1997 COMPARED WITH 1996

Sales in the life sciences segment increased $21.5 million, or 7%, in 1997. An
11% increase in unit volume was somewhat offset by a 4% unfavorable effect of
currency translation rates. Operating income increased $4.8 million, or 10%, in
1997 primarily due to the favorable impact on gross margins of the higher sales
volume. Operating income in 1996 included a $2.6 million gain due to the receipt
of proceeds from a note related to the sale of a product line in 1990.

Sales in the nonwovens segment increased $4.8 million, or 2%, in 1997. A 3%
increase in unit volume was offset by a 1% unfavorable currency translation
effect. Sales of food packaging materials were stronger in 1997 compared with
1996. Operating income increased $1.1 million, or 3%, in 1997 primarily due to
higher sales and the inclusion in 1996 of costs associated with the realigning
of the nonwoven operations in Europe.

Sales in the specialty polymers segment increased $20.5 million, or 4%, in 1997.
The net effect of acquired and divested businesses increased sales by $3.7
million, or 1%. Net of acquired and divested businesses, sales increased 3% due
to an 8% increase in unit volume offset by unfavorable currency translation
effects of 4% and selling price decreases averaging 1%. Increased volume in both
the electronic materials and aerospace businesses were partially offset by lower
sales of food and beverage can coatings serving the international markets.
Operating income increased $12.8 million, or 34%, in 1997 primarily due to
higher gross margins in the electronic materials business resulting from sales
volume increases and favorable product mix, and higher gross margins in the
aerospace business primarily due to increased sales volume and productivity
improvements. These increases were partially offset by lower operating income in
the international food and beverage can coatings business resulting from
decreased sales volume and unfavorable currency translation effects.

CASH AND SHORT-TERM SECURITIES Cash principally comprises in-transit funds in
the United States and amounts in operating bank accounts in other countries.

Short-term securities have maturities of less than 90 days when purchased and
represent cash awaiting use in the business, funds available for future
investment, and partial offsets of net nonlocal currency exposures relating to
current accounts payable and accounts receivable. Short-term securities are held
in interest-bearing overnight instruments, time deposits, prime commercial paper
and other fixed income investments. The carrying value of short-term securities
approximates fair value because of the short maturity of these instruments. At
December 31, 1998, there were $102.5 million in short-term securities, of which
$50.2 million were directly available to Dexter and $52.3 million were
maintained separately by LTI due to its different shareholder constituency. Of
these amounts, $34.2 million for Dexter and $28.1 million for LTI were held
outside the United States. Of the $50.2 million for Dexter, $22.8 million was
held by Dexter's captive insurance company.

ACCOUNTS RECEIVABLE Gross accounts receivable of $213.6 million at December 31,
1998 were reduced by allowances of $9.7 million. Such allowances were $10.4
million at December 31, 1997 and $8.1 million at December 31, 1996. Currency
translation effects increased net accounts receivable by $4.4 million in 1998.
Included in accounts receivable are non-trade accounts receivable of $18.3
million in 1998 compared with $11 million in 1997 and $13.2 million in 1996.
These amounts principally comprise tax receivables. The collection period for
accounts receivable increased to approximately 58 days at December 31, 1998,
compared with 53 days at December 31, 1997 and 57 days at December 31, 1996.

INVENTORIES Inventories are valued at the lower of cost or market. Inventories
located in the United States represented 49% of total inventories. The LIFO
(last-in, first-out) method was used for determining the cost of 59% of U.S.
inventories in 1998 and 58% in 1997 and 1996. The FIFO (first-in, first-out)
method was used for determining the cost of the remaining 41% of inventories in
the United States and the 51% of total inventories which were located outside
the United States. The reduction in levels of LIFO valued inventories (LIFO
liquidation) was not significant in 1998, 1997 or 1996. Inventories at December
31 were as follows:

</TABLE>

FIFO inventories increased $15.7 million in 1998 to $194.4 million, primarily
due to higher inventories at LTI due to increased sales levels and a planned
finished goods inventory build in the nonwovens segment during the last quarter
of 1998.

PROPERTY, PLANT AND EQUIPMENT Capital expenditures on the accrual basis were
$48.4 million in 1998, $59.1 million in 1997 and $62.3 million in 1996. The
$62.3 million in 1996 includes a capital lease for $4.7 million at LTI for a
parcel of land, which was subsequently purchased in 1998. Capital expenditures
in 1999 are currently estimated to range between $55 million and $65 million.

For financial reporting purposes, the company uses the straight-line method of
computing depreciation on plant and equipment. This method charges the cost to
income evenly over the useful lives of the assets, principally 20 to 50 years
for buildings, 16 years for nonwovens related machinery and equipment, and 3 to
15 years for all other machinery and equipment. For tax purposes, the company
uses shorter lives and accelerated depreciation methods. Capital investment
incentive grants are recorded as a reduction of the cost of assets, which
spreads the benefits over the lives of the related assets through reduced
depreciation. Management evaluates, on an ongoing basis, the carrying value of
property, plant and equipment and makes a specific provision against an asset
when impairment is identified. Property, plant and equipment is written down
when the asset has become redundant or the remaining book value exceeds its
anticipated future productive asset value.

Maintenance and repairs are charged to operations as incurred and amounted to
$18.9 million in 1998, $18.3 million in 1997 and $16.3 million in 1996.
Betterments and major renewals are capitalized. The cost of assets sold or
retired and the related amounts of accumulated depreciation are eliminated from
the accounts and the resulting gains or losses are included in income.

The cost and accumulated depreciation of property, plant and equipment at
December 31, were as follows:

PATENTS, TECHNOLOGY, TRADEMARKS AND COVENANTS Patents, technology, trademarks
and covenants not to compete are stated at cost less accumulated amortization of
$22.6 million, $19.9 million and $18.5 million at December 31, 1998, 1997 and
1996, respectively. Such items that have been acquired by purchase or merger are
capitalized and amortized on a straight-line basis over periods ranging from 5
to 30 years. During 1998, the company acquired approximately $91.5 million of
such items as a result of the acquisition of an additional 22% of LTI. Research
and development costs and any costs associated with internally developed patents
or other proprietary technology are expensed in the year incurred.

EXCESS ACQUISITION COST Excess acquisition cost was $157 million at year-end
1998, $97.5 million at year-end 1997 and $71.9 million at year-end 1996. Excess
acquisition costs increased substantially in 1998 primarily due to $63.4 million
resulting from the increase in ownership of LTI and $1.9 million due to currency
translation effects. This increase was partially offset by $6.9 million of
amortization costs. Excess acquisition cost increased $34.5 million in 1997 due
to businesses acquired. This increase was somewhat offset by $5.6 million of
amortization costs and $3.3 million due to currency translation effects. The
excess of cost over the net asset value of businesses acquired prior to 1991 is
amortized on a straight-line basis over 25 to 40 years. Excess acquisition cost
of businesses acquired after 1990 is amortized over periods ranging from 5 to 30
years. Accumulated amortization amounted to $31.2 million, $23.8 million and
$18.8 million at December 31, 1998, 1997 and 1996, respectively. Management
evaluates, on an ongoing basis, the carrying value of excess acquisition cost
and makes a specific provision against the asset when impairment is identified.
When a loss is expected from the proposed sale of a business or product line, a
diminution in the value of the excess of cost over the net asset value of the
business acquired is identified. In the instance of an ongoing business, such a
diminution is recognized when there has been a history of the business'
inability to generate operating income after the amortization of goodwill and,
in management's judgment, the business will not recover from this position in
the future. There were no impairment charges in 1998, 1997 or 1996.

SHORT-TERM DEBT Short-term borrowings were denominated principally in U.S.
dollars, Japanese yen and pound sterling, and had maturities of three months or
less. The company uses short-term borrowings of less than three-month maturity
to partially offset net nonlocal currency exposures relating to current accounts
receivable and accounts payable. It can be expected that short-term borrowings
will continue to be utilized for this purpose. The $39.8 million short-term
borrowings outstanding at year-end included $2.2 million of short-term debt of
LTI. The weighted average interest rate on short-term borrowings outstanding was
6% at December 31, 1998, 6.1% at December 31, 1997, and 5.4% at December 31,
1996.

In December 1998, the company entered into a $300 million, 364-day revolving
credit agreement with a syndicate of U.S. and international banks. This
revolving credit agreement carries a facility fee that is based on the credit
ratings of the company. At December 31, 1998, the facility fee on the revolving
credit agreement was 0.10% per annum. A utilization fee of up to 0.10% per annum
will also be charged if the utilization of the revolving credit agreement
exceeds certain contractual levels. This revolving credit agreement has a
minimum consolidated net worth provision and a maximum leverage ratio. At
December 31, 1998, the company was in compliance with these provisions. There
were no borrowings under the 364-day revolving credit agreement as of December
31, 1998. In addition, the company has available short-term lines of credit in
excess of $100 million.

The company had outstanding letters of credit at December 31, 1998 totaling
$10.5 million for liabilities already reflected in the Statement of Financial
Position. In addition to its 364-day revolving credit facility, the company has
authorized the borrowing of up to $100 million under its short-term lines of
credit and commercial paper program. There was no commercial paper issued during
1998.

ACCRUED LIABILITIES AND EXPENSES Accrued liabilities and expenses at December 31

LEASES The company leases facilities, vehicles, computers, and other equipment
under long-term operating leases with varying terms and expiration dates. Some
leases contain renewal provisions, purchase options, and escalation clauses.

Obligations under capital leases were not significant at December 31, 1998. At
December 31, 1997 and 1996, LTI had a capital lease in the amount of $4.7
million for a parcel of land on which they constructed a new corporate R&D
center and other administrative offices, including their headquarters. In 1998,
LTI exercised their option to purchase this parcel of land.

Aggregate future minimum lease payments under noncancelable operating leases as
of December 31, 1998, were as follows:

</TABLE>

Total rent expense incurred under noncancelable leases, net of minor sublease
rentals, amounted to $15.5 million in 1998, $11.5 million in 1997 and $10.9
million in 1996. The company has no contingent rentals.

MINORITY INTERESTS Minority interests decreased by $20.1 million in 1998 to
$84.3 million. The decrease in 1998 was due principally to the company's
increased ownership of LTI. In December of 1998, the company acquired
approximately 22% of all the issued and outstanding LTI shares. As a result,
Dexter's ownership in LTI increased to approximately 71% and the corresponding
minority interest ownership decreased to 29%. This resultant decrease of
approximately $61.7 million was partially offset by $15 million of net income
attributable to the minority interest shareholders of LTI, $27.2 million due to
the exercise of stock options at LTI and currency translation effects of $1.6
million. Somewhat offsetting these increases were quarterly cash dividends paid
by LTI to minority interest shareholders totaling $2.3 million. At year-end
1997, minority interests were $104.4 million, an increase of $14 million from
1996 minority interests of $90.4 million. The increase in 1997 was principally
due to $15.2 million of net income attributable to the minority interest
shareholders of LTI and a $4.7 million increase due to the exercise of stock
options at LTI. These increases in minority interests were somewhat offset by
currency translation effects of $4.1 million and cash dividends paid by LTI to
minority interest shareholders of $1.9 million. Minority interest in LTI's
equity represented $78.9 million and $99.3 million at December 31, 1998 and
1997, respectively.

CONTINGENCIES The company and its subsidiaries are subject to potential
liability under government regulations and various claims and legal actions
which are pending or may be asserted. These claims and legal actions 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 December 31, 1998, $0.2 million of current and $5.1 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. Estimated amounts for claims which are
probable and are not covered by third-party insurance are properly reflected 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.

ENVIRONMENTAL LIABILITIES Environmental expenditures attributed to ongoing
operations of the company are expensed or capitalized as appropriate.
Environmental expenditures attributed to previously owned properties and third
party off-site facilities are expensed. Liabilities related to environmental
assessments, site remediation and other response activities are recorded and
expensed when incurrence of the liability is probable and the expenses can be
reasonably estimated. Generally, the incurrence of such liability is deemed
probable when an environmental condition for which the company is likely to be
legally responsible is determined to exist. Probable expenses are estimated, on
an ongoing basis, as facts become available that indicate the scope of the
condition to be addressed and the likely response measures for addressing it.
Due to such factors as the wide discretion of regulatory authorities regarding
cleanup levels and uncertain allocation of liability at multiple party sites,
estimates made prior to approval of a formal plan of action represent
management's best judgment as to estimates of reasonably foreseeable expenses
based upon comparison to similar activities at other sites.

Environmental reserves at December 31, 1998, with respect to 17 sites, were
$15.3 million, including current reserves of $1.8 million, which are expected to
be spent in 1999, and long-term reserves of $13.5 million. Environmental
reserves at December 31, 1997 were $15.8 million and at year-end 1996 were $16.3
million. Such reserves, which are not discounted, included, at year-end, the
following estimated amounts for claims accepted and payable by third-party
insurers: $2.8 million in 1998, $2.7 million in 1997, and $2.5 million in 1996.
The related receivables from insurance companies of $2.8 million, $2.7 million,
and $2.5 million were included as assets of the company at year-end 1998, 1997
and 1996, respectively. The reserves were decreased during 1998 by expenditures
of $0.6 million.

Dexter Environmental Assurance, Ltd. ("DEAL"), a wholly owned Bermuda company,
was established in 1993. In December 1993, environmental reserves totaling $5.9
million were transferred to DEAL to insure all wholly owned U.S. operations of
Dexter, other than exposures in Windsor Locks, Connecticut, against
environmental liabilities arising from occurrences prior to January 1, 1994. In
November 1994, environmental reserves totaling $5 million were transferred to
DEAL. With the second transfer, the coverage period was extended to include
occurrences after December 31, 1993 and prior to January 1, 1995 for all wholly
owned U.S. operations of Dexter. In December 1997, environmental reserves
totaling $0.4 million were transferred to DEAL. With this transfer, the coverage
became available to all wholly owned operations of Dexter, U.S. and non-U.S.,
against environmental liabilities arising from occurrences prior to January 1,
1998. The covered periods have since been extended through December 31, 1998.

CURRENCY EXCHANGE EFFECTS Assets and liabilities of those operations whose
functional currency is other than the U.S. dollar are translated at end of
period currency exchange rates and fluctuations due to changes in exchange rates
are accounted for as a component of shareholders' equity, "Currency Translation
Effects". Results of operations are translated at average monthly currency
exchange rates during the period.

Currency translation effects increased shareholders' equity in 1998 by $4.6
million, including $3.6 million of translation effects and a $1 million related
tax effect. This increase was the result of the net weakening of the U.S. dollar
against currencies of countries in which the company operates. Currency
translation effects decreased shareholders' equity by $20.3 million in 1997,
including $20.5 million of translation effects partially offset by a $0.2
million related tax effect.

Many of the company's operations conduct a portion of their business in nonlocal
currencies. These transactions give rise to nonlocal currency receivables or
payables. Changes in the exchange rates between the functional currency and the
nonlocal currency in which the transaction is denominated result in currency
transaction gains and losses that are included in the results of operations.
Currency gains and losses realized on these nonlocal currency transactions were
not significant in 1998, 1997 or 1996.

The company utilizes forward exchange contracts to hedge nonlocal currency
transactions and commitments. Gains and losses on forward exchange contracts
that hedge specific commitments are deferred and recognized in income in the
same period as the hedged transaction. Such deferred unrealized gains and losses
at December 31, 1998, 1997 and 1996 were not significant. Gains and losses on
forward contracts that do not hedge an identifiable commitment are included in
income as the gain or loss arises. Forward exchange contracts outstanding at
year-end 1998 were short-term in nature and related to nonlocal currency
transactions of the company's U.S., European and Asian operations. Excluding
LTI, the equivalent U.S. dollar purchase amounts of forward contracts
outstanding were $1.3 million, $0.8 million and $1 million as of December 31,
1998, 1997 and 1996, respectively. The equivalent U.S. dollar sale amounts of
the forward contracts outstanding were $13.8 million, $9.6 million, and $7.5
million as of December 31, 1998, 1997 and 1996, respectively. For LTI, the
equivalent U.S. dollar purchase amounts of its forward contracts were $3
million, $2.9 million, and $6.2 million as of December 31, 1998, 1997 and 1996,
respectively. There were no sale amounts outstanding as of December 31, 1998,
1997 and 1996 for LTI.

The market risk associated with forward exchange contracts is caused by
fluctuations in exchange rates subsequent to entering into the forward exchange
contracts. Credit risk associated with forward exchange contracts is caused by
nonperformance by the counterparties to these financial instruments. The company
does not believe there is significant risk of nonperformance by the
counterparties to these financial instruments.

The company had short-term borrowings at December 31, 1998 of $39.8 million of
which $5.1 million related to nonlocal currency transaction exposure management.

POSTRETIREMENT BENEFITS Effective December 31, 1998, the company adopted SFAS
No. 132, Employers' Disclosures about Pensions and Other Postretirement
Benefits. The provisions of SFAS No. 132 standardize the disclosure requirements
for pensions and other postretirement benefits and do not change the measurement
or accounting of these plans.

The company has pension (defined benefit) or deferred profit sharing (defined
contribution) plans for substantially all U.S. employees. Retirement benefits
for most employees of international operations are provided by
government-sponsored or insured programs and, in certain countries, by defined
benefit plans.

The components of net periodic pension cost for the years ended December 31,
1998, 1997 and 1996 were:

* In June of 1996, the company recognized a $1.1 million curtailment gain
  resulting from the sale of its Automotive businesses. At June 30, 1996, the
  Dexter Pension Plan was remeasured using a 7.5% discount rate.


The company sponsors deferred profit sharing plans for substantially all
domestic employees not covered under pension plans. Contributions and cost are
determined based on a percentage of each covered employees' pay and totaled $7.2
million in 1998, $8.1 million in 1997 and $7.3 million in 1996.

In addition to providing pension benefits, Dexter's wholly owned domestic
businesses provide some healthcare and life insurance benefits for retired
employees. Dexter has funded trusts for future payment of such benefits. These
funds are expected to achieve long-term returns in excess of 10%.

* 1996 benefits paid are net of plan participants' contributions.

The discount rates used in determining the accumulated postretirement benefit
obligation were 6.5%, 6.75%, and 7% at December 31, 1998, 1997 and 1996,
respectively. In June 1996, the company recognized a $1.6 million curtailment
gain resulting from the sale of its Automotive businesses. At June 30, 1996, the
accumulated postretirement benefit obligation was remeasured using a 7.5%
discount rate.

The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation was 9.5% in 1998, declining gradually to 5% in
2007 and remaining level thereafter.

Assumed health care cost trend rates have a significant effect on the amounts
reported for the postretirement health benefit plan. A one-percentage point
change in assumed healthcare cost trend rates would have the following effects:

LONG-TERM DEBT Long-term debt at December 31, 1998, consisted of promissory
notes, revolving credit borrowings and sinking fund debentures.

In December 1998, the company entered into a $300 million, 5-year revolving
credit agreement with a syndicate of U.S. and international banks. This
revolving credit agreement replaced the $100 million multi-currency revolving
credit agreement in effect during 1998 and 1997 and carries a facility fee that
is based on the credit ratings of the company. At December 31, 1998, the
facility fee on the revolving credit agreement was 0.125% per annum. A
utilization fee of up to 0.10% per annum will also be charged if the utilization
of the revolving credit agreement exceeds certain contractual levels. This
revolving credit agreement has a minimum consolidated net worth provision and a
maximum leverage ratio. At December 31, 1998, the company was in compliance with
these provisions. As of December 31, 1998, the company had borrowings under the
5-year revolving credit agreement of $216 million at an annual rate of 5.925%.

In March 1998, the company entered into a $10 million floating rate promissory
note due in the year 2001. The company also entered into an interest rate swap
agreement expiring in the year 2001 in order to limit the exposure to interest
rate volatility on the $10 million floating rate promissory note. The swap
agreement resulted in a fixed annual rate of 6.315%. At December 31, 1998,
termination of the swap agreement would result in a loss of $0.2 million.

In March 1998, the company borrowed the Swiss franc denominated equivalent of
approximately $20 million under a floating rate promissory note due in the year
2003. Payments of 14.9 million Swiss francs are due in each of the years 2002
and 2003. The company also entered into an interest rate swap agreement expiring
in the year 2003 to limit exposure to interest rate volatility on the 29.8
million Swiss franc floating rate promissory note. The swap agreement resulted
in a fixed annual rate of 2.98%. At December 31, 1998, termination of the swap
agreement would result in a loss of 0.6 million Swiss francs or the equivalent
of approximately $0.4 million. The company monitors the risk of default on the
swap agreements and does not anticipate nonperformance by the counterparties.

In 1996, LTI capitalized a lease for a parcel of land on which a new R & D
center and other administrative offices were constructed. In March 1998, LTI
exercised their option under the lease to purchase the land.

In 1996, Dexter refinanced 350 million yen debt and borrowed an additional 150
million yen at an annual rate of 1.66%. The total borrowing of 500 million yen
(equivalent to approximately $3.8 million) is scheduled to mature in the year
1999.

In November 1993, Dexter privately placed with The Prudential Insurance Company
of America, $35 million, 20-year senior unsecured notes at an annual rate of
6.21% due in the year 2013. Required prepayments began in 1994 and are scheduled
to continue with installments of $1.75 million per year through the year 2013.
In December 1993, Dexter privately placed with The Prudential Insurance Company
of America, the equivalent of $15 million, 15-year senior unsecured notes
denominated in Swiss francs at an annual rate of 4.86% due in the year 2008.
Required prepayments began in 1994 with installments of 2.2 million Swiss francs
per year through the year 1997, decreased to 1.5 million Swiss francs in 1998
which will continue through the year 2004, and decrease further to 0.8 million
Swiss francs from the year 2005 through the year 2008.

In November 1991, Dexter privately placed with The Prudential Insurance Company
of America, $50 million, 20-year senior unsecured notes at an annual rate of
8.96% due in the year 2011. Required prepayments of $2.5 million per year began
in 1998 and will continue through the year 2000. The installments increase to
$3.5 million per year from 2001-2010, with a final lump sum payment of $7.5
million due at maturity.

In July 1990, Dexter privately placed with The Prudential Insurance Company of
America, $75 million, 20-year senior unsecured notes at a rate of 9.72% due in
the year 2010. Required prepayments began in 1996 and are scheduled to continue
with installments of $5 million per year through maturity.

In December 1986, the company sold publicly $50 million, 9.25% sinking fund
debentures due in 2016. The sinking fund payments commenced in 1997 and were
designed to retire 95% of the debt prior to maturity. During 1997, Dexter
redeemed $30 million of the 9.25% sinking fund debentures in advance of their
maturities at a redemption price of 104.625%. Also, in December 1997 and
December 1998, Dexter made optional sinking fund payments of $5 million on these
debentures in addition to the scheduled, mandatory sinking fund payments of $2.5
million. The redemption price of the optional and mandatory sinking fund
payments was 100%.

The company has $50 million of authorized and unissued medium-term notes.

                                       36

Long-term debt represented 49.6% of total capital at December 31, 1998. The
weighted average interest rate of long-term debt outstanding at December 31,
1998 was 6.70%.

Certain long-term debt agreements include provisions that restrict the amount of
future dividend increases if consolidated equity falls below $175 million. There
are also provisions placing limits on the amount of additional debt the company
may incur without amendment of the agreements. At December 31, 1998, the company
was in compliance with these provisions.

LTI has guaranteed approximately $0.3 million of bank loans to others.

At December 31, 1998, 1997 and 1996, the fair value of net long-term debt was
$391 million, $188 million, and $218 million, respectively, compared with the
carrying value of $382 million, $180 million, and $210 million, respectively.
The fair value of long-term debt is based on quoted market prices for similar
issues or on the current rates offered to the company for debt of the same
remaining maturities. In 1998, the fair value of long-term debt exceeded the
carrying value by $9 million due to the net reduction in interest rates
subsequent to the issuance of the long-term debt and the consequent increase in
fair value. The company is only obligated to repay the amounts reflected in the
carrying value of this debt.

SHAREHOLDERS' EQUITY Shareholders' equity increased by $15.7 million in 1998 to
$388.5 million representing a book value of $16.86 per share. Net income
increased shareholders' equity by $31.7 million. The exercise of stock options
along with the impact of restricted stock awards added $2.8 million to
shareholders' equity in 1998, while Other Comprehensive Income added $4.7
million. Offsetting these increases were reductions due to dividends declared of
$23.5 million.

In 1990, the Board of Directors authorized a repurchase of up to 1,000,000
shares of the company's outstanding common stock. In 1995 and 1996, the company
purchased 1,000,000 shares of its outstanding common stock at an average cost of
$25.59 per share under this plan. In 1996, the Board of Directors authorized the
repurchase of an additional 1,000,000 shares of the company's outstanding common
stock and the company purchased 160,400 shares of its outstanding common stock
at an average cost of $32.54 per share under this plan in 1996. In 1997, the
company purchased 671,200 shares of its outstanding common stock at an average
cost of $30.57 per share under this plan. At the end of 1998, there were
1,702,704 shares held in treasury compared with 1,814,035 shares at the end of
1997 and 1,520,261 shares at the end of 1996.

In 1998, the company adopted SFAS No. 130, Reporting Comprehensive Income. This
statement establishes rules for the reporting of comprehensive income and its
components. Comprehensive income consists primarily of net income and foreign
currency translation adjustments and is presented in the Statement of Changes in
Shareholders' Equity. The adoption of SFAS No. 130 has no impact on total
shareholders' equity.

PREFERRED STOCK The company has the following classes of preferred stock,
without par value, as of December 31, 1998:

 Preferred Stock, Class II             500,000 shares
 Preferred Stock, Series A             250,000 shares
</TABLE>

PREFERRED STOCK, SERIES A - PURCHASE RIGHTS

In August 1996, the company authorized and declared a dividend distribution of
one right for each share of common stock of the company outstanding at the close
of business on November 17, 1996, and authorized the issuance of one right for
each share of common stock of the company issued between November 17, 1996 and
the distribution date. Each right entitles the holder to purchase one
two-hundredth of a share of Series A Preferred Stock of the company at a
purchase price of $90 per right. The rights will trade with the common stock and
not be exercisable or transferable apart from the common stock until 10 days
following the acquisition of, or tender offer for, 20% or more of the
outstanding shares of the common stock. The rights plan also provides that if
the company merges with or into another entity or sells or otherwise transfers
more than 50% of the assets or earning power of the company, the holder of each
right shall have the right to receive, upon exercise, shares of common stock
having a value equal to two times the exercise price.

The rights, which do not have voting privileges, are redeemable under certain
circumstances at a redemption price of $.01 per right and will expire, unless
earlier redeemed, on August 31, 2006. The company has authorized 250,000 shares
of Series A Preferred Stock for issuance upon exercise of the rights.

STOCK COMPENSATION PLANS The company applies APB Opinion No. 25, Accounting for
Stock Issued to Employees, and related interpretations in accounting for its
stock-based compensation plans described below. Accordingly, no compensation
cost has been recognized for its fixed stock option plans. Compensation expense
for its restricted stock plan is adjusted on a quarterly basis to reflect
changes in the market price of the stock. The compensation cost that has been
charged against income for the restricted stock plan was $1.1 million in 1998,
$2.1 million in 1997 and $1.2 million in 1996. Had compensation cost for the
company's stock-based compensation plans been determined in accordance with SFAS
No. 123, Accounting for Stock-Based Compensation, the company would have
expensed $1.4 million for its fixed stock option plans and an additional $0.2
million for its restricted stock plan in 1998. As a result, 1998 net income
would have decreased by $1.1 million, or $.05 per share. The net impact of SFAS
No. 123 on the company's net income and earnings per share was not significant
in 1997 or 1996.

The SFAS No. 123 method of accounting has not been applied to options or
restricted stock granted prior to January 1, 1995. As a result, compensation
cost may not be representative of that to be expected in future years.

The weighted average fair value at date of grant for options granted during
1998, 1997 and 1996 was $8.47, $6.90 and $7.14 per option, respectively. The
fair value of options at date of grant was estimated using the Black-Scholes
model with the following weighted average assumptions:

STOCK PLANS

1994 LONG-TERM INCENTIVE PLAN AND DATA

In 1994, Dexter established a long-term incentive plan for certain key
management of the company. The aggregate number of shares of the company's
common stock that may be awarded under the 1994 Long-Term Incentive Plan is
1,200,000 shares. Restricted stock grants and stock option grants have been
awarded under this Plan. The Plan will terminate on April 28, 2004, after which
time no additional grants may be made. At December 31, 1998, there were 629,314
shares available for future grant under this Plan.

RESTRICTED STOCK

Under the 1994 Long-Term Incentive Plan, participants are granted restricted
stock awards at no cost to the recipient. As of the grant date, restricted stock
participants have the rights of shareholders, including the right to receive any
cash dividends and the right to vote the shares. Restricted stock awards are
subject to forfeiture provisions including the lapse of time and the achievement
of certain performance targets and have restrictions limiting the sale or
transfer of shares during the restriction periods defined in the Plan. The
expense relating to restricted stock awarded under this Plan is amortized over
the restriction period. The weighted average fair value at date of grant for
restricted stock granted during 1998, 1997 and 1996 was $41.09, $29.94 and
$27.06, respectively, which in each case was equal to the market value of the
company's common stock at the date of grant. The shares outstanding are
summarized as follows:

STOCK OPTIONS

Options granted under the 1994 Long-Term Incentive Plan have an exercise price
not less than 100% of the fair market value on the date of grant. Options
granted under the Plan generally become exercisable at the rate of 33 1/3% of
the shares each year starting one year after the date of grant. Each option
granted under the Plan lapses ten years after the date it was granted, or
earlier, as outlined under the provisions of the Plan.

In 1998, 276,921 options for shares of common stock were granted at a weighted
average exercise price of $40.80. During the year, 1,050 options, having a
weighted average exercise price of $41.41, were cancelled. At December 31, 1998,
no options were exercisable and 275,871 options were outstanding with a range of
exercise prices of $31.47 - $41.41, a weighted average exercise price of $40.80,
and a weighted average contractual life of approximately 6 years.
- -------------------------------------------------------------------------------

1988 STOCK OPTION PLAN AND DATA

The 1988 Stock Option Plan provides for the granting of incentive and
nonqualified stock options to purchase up to 1,000,000 shares of common stock.
No stock appreciation rights may be granted. The option price shall not be less
than 100% of the fair market value on the date of grant for incentive stock
options and not less than 80% of the market value on the date of grant for
nonqualified options. Options generally become exercisable at the rate of 33
1/3% of the shares each year starting one year after the date of grant. Each
option granted under the 1988 Plan lapses ten years after the date it was
granted, or earlier, as outlined under the provisions of the Plan. There have
been no nonqualified options issued under the Plan at less than fair market
value; therefore, no charges against income have been made.
