Basic earnings per common share have been computed by dividing net income by the
weighted-average number of common shares outstanding during the period.  Diluted
earnings per common share have been computed by dividing net income by the
weighted-average number of common shares outstanding plus an assumed increase in
common shares outstanding for dilutive securities.

The following table reconciles the weighted average number of common shares
outstanding during each period for basic earnings per share with the comparable
amount for diluted earnings per share.

Included in capital expenditures as of June 30, 1998 is $4,635 for the exercise
of an option to purchase land under a capital lease.

As of January 1, 1998, the Company adopted SFAS No. 130, Reporting Comprehensive
Income, which requires additional disclosures with respect to certain changes in
assets and liabilities that previously were not required to be reported as
results of operations for the period.

U.S. and international withholding taxes have not been provided on undistributed
earnings of foreign subsidiaries.  The Company remits only those earnings which
are considered to be in excess of the reasonably anticipated working capital
needs of the foreign subsidiaries, with the balance considered to be permanently
reinvested in the operations of such subsidiaries.  It is impractical to
estimate the total tax liability, if any, until such a distribution is made.

The following are included as components of Accumulated Other Comprehensive
Income.

In the opinion of the Company's management, the unaudited financial statements
reflect all adjustments (which consist of normal recurring adjustments)
necessary to present a fair statement of the results for the interim periods.

The results for the six-month period ended June 30, 1998 are not necessarily
indicative of the results for the year ending December 31, 1998.

On July 9, 1998, there was a public announcement by The Dexter Corporation
("Dexter"), the beneficial owner of approximately 52% of the Company's
outstanding common stock, of its intent to acquire the approximately 11.3
million shares of

                                       5

the Company common stock that Dexter does not currently own, at a price of $37
per share in cash.

Certain amounts for the 1997 year period have been reclassified to conform to
and be consistent with the 1998 presentation.

        Condition and Results of Operations
        -----------------------------------

Any statements in this quarterly report concerning the Company's business
outlook or future economic performance; anticipated profitability, revenues,
expenses or other financial items; together with other statements that are not
historical facts, are "forward-looking statements" as that term is defined under
the Federal Securities Laws.  Forward-looking statements are subject to risks,
uncertainties and other factors which could cause actual results to differ
materially from those stated in such statements.  Such risks, uncertainties and
factors include, but are not limited to, changes in government funding for life
sciences research, changes in pricing or availability of fetal bovine serum,
changes in currency exchange rates, changes and delays in new product
introduction, customer acceptance of new products, changes in government
regulations, changes in pricing or other actions by competitors and general
economic conditions, as well as other risks detailed in the Company's filings
with the Securities and Exchange Commission.

RESULTS OF OPERATIONS

SECOND QUARTER RESULTS

Revenues were $92.2 million in the second quarter of 1998, representing an
increase of 8% over the second quarter of 1997.  Net sales were $91.5 million in
the second quarter of 1998, an increase of $7.0 million, or 8%, compared with
the second quarter of 1997.  Net sales of products other than fetal bovine serum
(FBS) increased by $9.5 million, or 13%, when comparing the second quarter of
1998 with the comparable period of 1997 and excluding the effect of changes due
to different currency translation rates.  Second quarter 1998 FBS net sales were
unchanged from the second quarter of 1997 on a currency comparable basis as a 3%
unit sales increase was offset by a similar decline in average unit selling
prices.  FBS sales represented 12% of net sales in the second quarter of 1998
and 13% in the second quarter of 1997. Net sales in the second quarter of 1998
were $2.5 million, or 3%, lower than they would have been at the exchange rates
in effect in the second quarter of 1997. Royalty income was $0.7 million in the
second quarter of 1998 compared with $0.5 million in the second quarter of 1997.

Gross margins were 53.4% of net sales in the second quarter of 1998 compared
with 53.8% in the second quarter of 1997.  The strength of the U.S. dollar and
the British pound sterling relative to the Asian and Continental European

Part I - (continued)

currencies when comparing the second quarter of 1998 with the second quarter of
1997 unfavorably affected the comparison of gross margins in these two periods.
Marketing and administrative expenses were 32.1% of net sales in the second
quarter of 1998 and 32.3% in the second quarter of 1997. Income taxes were 35%
of income before taxes in the second quarter of 1998 compared with 36% of
income before  taxes in  the second  quarter  of  1997.  The effective income
tax rate was lower in the 1998 period principally due to the realization of a
higher proportion of taxable income in countries with lower tax rates as well as
greater benefits from tax credits recognized in the 1998 period.

Net income of $9.4 million in the second quarter of 1998 increased 13% over the
second quarter of 1997.  Diluted earnings per share of $0.39 in the second
quarter of 1998 were 11% greater than diluted earnings per share of $0.35 in the
comparable period of 1997.

SIX MONTHS RESULTS

Revenues in the first half of 1998 were $181.0 million, representing an increase
of 9% compared with revenues of $165.5 million in the first six months of 1997.
Net sales for the first half of 1998 were $179.9 million, an increase of $15.2
million, or 9%, over the first half of 1997.  Net sales of products other than
FBS in the first half of 1998 increased $20.0 million, or 14%, compared with the
first half of 1997 and excluding the effect of changes due to different currency
translation rates. FBS net sales increased $0.6 million, or 2%, on a currency
comparable basis as unit sales increased 5% and average unit selling prices
decreased 3%. FBS sales represented 12% of net sales in the first six months of
1998 compared with 13% of net sales in the comparable period of 1997. The effect
of changes in currency exchange rates reduced net sales in the first half of
1998 by $5.4 million, or 3%, when compared with the first half of 1997. Royalty
income was $1.1 million for the first six months of 1998 compared with $0.8
million in last year's first half.

Gross margins were 53.4% in the first half of 1998 compared with 54.4% in the
comparable 1997 period.  Unfavorable currency exchange rate comparisons were the
primary reason that gross margins declined.  FBS gross margins improved slightly
in the first half of 1998 compared with the first half of 1997 as unit costs
decreased at a greater rate than unit selling prices. Marketing and
administrative expenses were 32.5% of net sales in the first six months of 1998
and 32.8% in the comparable period of 1997. Income taxes were 35% of income
before taxes in the first half of 1998 compared with 36% of income before taxes
in the first half of 1997.

For the first six months of 1998, net income of $18.1 million increased 12% over
1997.  Diluted earnings per share for the first half of 1998 were $0.75, an
increase of 10% compared with the first half of 1997.

LIQUIDITY AND CAPITAL RESOURCES

Operating activities provided $19.6 million in cash during the first six months
of 1998.  Net income after adjustments for depreciation and amortization was

                                       7
<PAGE>
 
Part I - (continued)

the principal source of cash from operations in 1998.  Working capital increases
were the principal use of cash from operations.

The Company paid $17.4 million for capital expenditures in the first six months
of 1998. Capital expenditures included $4.6 million for the exercise of an
option to purchase land under a capital lease. The Company also paid $1.0
million in deferred purchase payments related to the 1996 acquisition of Custom
Primers Inc.

Cash used for financing activities included $2.3 million for quarterly dividend
payments in the first six months of 1998.  The Company paid $1.4 million to
reduce outstanding loans to several banks and reduce the principal balance on a
capital lease. The Company received $3.2 million from the exercise of stock
options.

The Company is in the process of replacing its core financial, order
entry/distribution, and manufacturing systems at its major locations worldwide.
The Company has been advised by its software vendor that the release/version of
the software being implemented by the Company is Year 2000 compliant.  The
Company is also conducting a review of other internal and external systems which
may require modification or upgrade to be made Year 2000 compliant.  The Company
is in the process of working with its customers and suppliers to identify,
modify or upgrade its existing systems which are not currently Year 2000
compliant.  The Company believes that the cost of completing the modifications
necessary to become Year 2000 compliant will not be material.  There can be no
assurance, however, that the Company will be able to identify all aspects of its
business that are subject to Year 2000 problems, or identify Year 2000 problems
of customers or suppliers that affect the Company's business.  There also can be
no assurance that the Company's software vendors are correct in their assertions
that the software is Year 2000 compliant or that the Company's estimate of the
cost of systems preparation for Year 2000 compliance will prove ultimately to be
accurate.

Capital expenditures in 1998 are expected to range from $30-35 million. The
Company is contemplating additional facility upgrades and expansions of $20-25
million with the balance of expected 1998 capital expenditures for new and
replacement machinery, equipment and management information systems.

The Company is actively evaluating licensing possibilities, as well as
acquisition candidates which complement the Company's core cell and molecular
biology and cell culture product lines.  The Company believes it will be able to
generate sufficient cash from its operations and its existing credit facility to
meet all its anticipated cash requirements in 1998 apart from any significant
business acquisition which may occur and which may be financed using cash from
operations, debt, equity, or other sources.

NEW ACCOUNTING PRONOUNCEMENT

The Financial Accounting Standards Board has issued, SFAS No. 131, Disclosures
about Segments of an Enterprise and Related Information, which became effective
for reporting periods beginning after December 15, 1997.  Interim reporting is

                                       8
<PAGE>
 
Part I - (continued)

not required under SFAS No. 131 prior to adoption.  SFAS No. 131, Disclosures
about Segments of an Enterprise and Related Information, requires financial and
descriptive information with respect to "operating segments" of an entity based
on the way management disaggregates the entity for making internal operating
decisions. The Company will begin making the disclosures required by SFAS No.
131 with financial statements for the period ending December 31, 1998.  There
will be no financial impact from the adoption of SFAS No. 131.  SFAS No. 131 has
a disclosure impact, as there will be further disclosures, as results are
disaggregated.

The Financial Accounting Standards Board has issued, SFAS No. 133, Accounting
for Derivative Instruments and Hedging Activities, which becomes effective for
years beginning after June 15, 1999.  SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, requires that every derivative instrument be
recorded in the balance sheet as either an asset or liability measured at its
fair value.  The statement requires that changes in the derivative's fair value
be recognized in earnings unless specific hedge accounting criteria are met.
The Company believes that the effect of adoption of SFAS No. 133 will not be
material.

by The Dexter Corporation ("Dexter"), the beneficial owner of approximately 52%
of the Company's outstanding common stock, of its intent to acquire the
approximately 11.3 million shares of Company common stock that Dexter does not
currently own, at a price of $37 per share in cash (approximately $420 million,
excluding payment for vested stock options), subject to certain conditions, a
lawsuit purporting to be brought as a class action on behalf of the Company's
public stockholders was filed against the Company, Dexter and the Company's
directors in the Court of Chancery of the State of Delaware (Civil Action No.
16513NC), by Ellis Investments, Ltd. ("Ellis"), which claims to be a stockholder
of the Company.  Ellis' complaint alleges, among other things, that the
defendants have breached and/or may breach their respective fiduciary duties and
seeks to enjoin, preliminarily and permanently, the proposed action and to
recover monetary damages and costs. Several additional lawsuits were
subsequently filed in the same court as purported stockholder class actions and
make similar claims.  Counsel for plaintiffs in the Ellis lawsuit and the
additional lawsuits have advised the Company that they will seek to consolidate
the additional lawsuits with the Ellis lawsuit and to designate the Ellis
complaint as the operative complaint in the consolidated litigation.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Stockholders and Board of Directors
Life Technologies, Inc.


We have reviewed the accompanying consolidated balance sheet of Life
Technologies, Inc. and its subsidiaries as of June 30, 1998 and the related
consolidated statements of income and comprehensive income for the three-month
and six-month periods ended June 30, 1998 and 1997, and the related condensed
consolidated statement of cash flows for the six-month periods then ended.
These financial statements are the responsibility of the Company's management.

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

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

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet as of December 31, 1997 and the
related consolidated statements of income, stockholders' equity and cash flows
for the year then ended (not presented herein), and in our report dated January
23, 1998 we expressed an unqualified opinion on those consolidated financial
statements.

             form of consideration for such Common Stock shall be either cash or
             the form used to acquire the largest number of shares previously
             acquired by it.

             to reflect any reclassification (including any reverse stock
             split), recapitalization, reorganization or similar transactions
             which has the effect of reducing the number of outstanding shares
             of Common Stock, unless the failure so to increase such annual rate
             is approved by two-thirds of the Continuing Directors, and (b) such
             Related person shall not have become the beneficial owner of any
             additional shares of voting stock of the Company except as part of

             Person shall not have received the benefit, directly or indirectly

             guarantees, pledges or other financial assistance or any tax credit
             or other tax advantages provided by the Corporation, whether in
             anticipation of or in connection with such Business Combination
             with a Related Person or otherwise.

             (whether or not such proxy or information statement is required to
             be mailed pursuant to such Act or subsequent provision).

   (3)  A majority of the members of the Board of Directors acting upon such
        transaction are Continuing Directors, and at least seventy-five percent

        (ix)   The term "Subsidiary" shall mean any corporation of which a
               majority of any class of equity security is owned, directly or
               indirectly, by the Corporation.

        (x)    "Fair Market Value" shall mean: (a) in the case of stock, the
               highest closing sale price during the thirty (30) day period
               immediately preceding the date in question of a share of such
               stock on the Composite Tape for the New York Stock Exchange
               Listed Stocks, or, if such stock is not quoted on the Composite
               Tape, on the New York Stock Exchange, or, if such stock is not
               listed on such Exchange, on the principal United States
               securities exchange registered under the Securities Exchange Act
               of 1934 on which such stock is listed, or if such stock is not
               listed on any such exchange, the highest closing bid quotation
               with respect to a share of such stock during the thirty (30) day
               period immediately preceding the date in question on the National
               Association of Securities Dealers, Inc., Automated Quotations
               Systems, or any system then in use, or if no such quotations are
               available, the Fair Market Value on the date in question of a
               share of such stock as determined by the Continuing Directors in
               good faith; or (b) in the case of property other than cash or
               stock, the Fair Market Value of such property on the date in
               question as determined by the Continuing Directors in good faith.

        (xi)   The majority of the Continuing Directors shall have the power and
               duty to determine for the purposes of this reasonable inquiry,
               (a) whether a person is a Related Person, (b) the number of
               shares of voting stock of the Company beneficially owned by any
               person, (c) whether a person is an Affiliate or an Associate of
               another, and (d) what the Fair Market Value is of the

<PAGE>
 
                 Subsidiary in any Business Combination or Business Combination
                 with a Related Person.

                 NINTH:  No holders of any class of shares of the Corporation
          shall have any pre-emptive right to purchase or have offered to them
          for purchase any shares or other securities of the Corporation.

                 TENTH:  The Directors of the Corporation shall be divided into
          three classes.  Each class of Directors shall consist of not fewer
          than three nor more than five Directors (provided that the whole
          number of Directors of any class shall not exceed the whole number of
          Directors of any other class by more than one).  The number of
          Directors in each class may from time to time be determined by the
          vote of at least seventy-five percent (75%) of the Directors.  The
          term of each class shall expire in different years.  At each annual
          meeting the successors to the Directors of each class whose term shall
          expire in that year shall be elected to hold office for a term of
          three (3) years from the date of their election and until the election
          of their successors.  In case of any increase in the number of
          Directors of any class, any additional Directors elected to such class
          shall hold office for a term which shall coincide with the term of
          such class.  The affirmative vote of the holders of not less than
          eighty percent (80%) of the Common Stock of the Corporation shall be
          required to remove from office any or all of such classified
          Directors, or all of the Directors of a particular class. A Director
          may be removed from office only for cause.  As used in this Article
          TENTH, the term "cause" means fraud, criminal conduct or gross abuse
          of office amounting to a breach of trust.  Any stockholder proposing
          to remove a director shall (i) request, in accordance with the
          requirements of the Bylaws of the corporation, that a special meeting
          of the stockholders be called, or notify the corporation that such
          proposal shall be presented at the annual meeting of stockholders, and
          (ii) state, in the request for such a meeting or in such notification,
          in detail all the particular reasons and circumstances as a result of
          which such removal for cause is justified.  Any director proposed to
          be so removed shall be permitted an opportunity to be heard by the
          stockholders to rebut such charges before any vote for removal is
          taken.

                 ELEVENTH:  The affirmative vote of the holders of not less than
          eighty percent (80%) of the outstanding shares of Common Stock of the
          Corporation shall be necessary to alter, change or repeal any
          provision contained in this Certificate of Incorporation, or to adopt
          a new Certificate of Incorporation.

                 TWELFTH:  Meetings of the stockholders may be held within or
          without the State of Delaware, as the Bylaws may provide.  The books
          of the Corporation may be kept (subject to any provisions contained in
          the statutes) outside the State of Delaware at such place or places as
          may be designated from time to time by the Board of Directors or in
          the Bylaws of the Corporation.  Elections of directors need not be by
          written ballot unless the Bylaws of the Corporation shall so provide.

                 I, THE UNDERSIGNED, being the sole incorporator hereinbefore
          named, for the purpose of forming a corporation pursuant to the
          General Corporation Law of the State of Delaware, do make this

liable to the Corporation or any of its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (i) for any breach
of the director's duty of loyalty to the Corporation or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law, as the same exists or hereafter may be amended, or (iv) for any
transaction from which the director derived an improper personal benefit.  If
the Delaware General Corporation Law hereafter is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation in addition to the limitation on
personal liability provided herein, shall be limited to the fullest extent
permitted by the amended Delaware General Corporation Law.  Any repeal or
modification of this paragraph by the stockholders of the Corporation shall be
prospective only, and shall not adversely affect any limitation on the personal
liability of a director of the corporation existing at the time of such repeal
or modification."

          SECOND:  That hereafter, pursuant to resolution of its Board of
Directors, the annual meeting of stockholders of said Corporation was duly
called and held, at which meeting the necessary number of stockholders as
required by statute voted in favor of the amendment.
