SUBJECT LINE: IMPORTANT COMPANY ANNOUNCEMENT

May 8, 2006

Dear Colleague,

This is an historic day for Thermo. Today we announced our plans to combine with
Fisher to create THE leading life, laboratory and health sciences company in the
industry. The combination of our complementary technology leadership positions
in instrumentation, life science consumables, software and services will provide
farther-reaching integrated solutions for our joint customers around the world.

For those of you who may not be familiar, Fisher is a leading provider of
products and services to the global scientific research and clinical laboratory
community. Fisher and its 19,500 employees serve more than 350,000 customers
around the world, including pharmaceutical and biotech companies, colleges and
universities, medical-research institutions, hospitals and R&D laboratories, as
well as government agencies.

Upon the close of this transaction, the new company will be called Thermo Fisher
Scientific. It will be headquartered out of our offices in Waltham, MA, and I
will serve as Thermo Fisher's president and chief executive officer. Paul M.
Meister, currently vice chairman of the board for Fisher, will be chairman of
the combined company. The joint press release we issued regarding this exciting
combination can be found in a special new section, Thermo Fisher Scientific
News, on Thermo.net.

We believe Fisher Scientific is the perfect strategic fit for Thermo. Together,
we will have:

     o    Combined annual revenues of approximately $9 billion (USD);
     o    Complementary technology leadership positions in instrumentation, life
          science consumables, software and services combined with unparalleled
          customer connectivity to effectively reach and further penetrate a
          highly fragmented customer base and accelerate growth;
     o    Enhanced international presence in emerging markets, customer reach
          and opportunities for cross-selling;
     o    Increased cash flow and a solid balance sheet that will position us to
          accelerate earnings growth both organically and through acquisitions;
     o    An exceptional team of 30,000 talented and experienced employees. We
          expect this combination of industry leaders to benefit our customers
          and to result in greater opportunities for both companies' employees.

I believe this is a compelling combination and hope you share my enthusiasm.
Change of this magnitude, of course, raises many questions for employees. Our
pledge is to be as informative as possible as we progress toward closing this
transaction and during the integration period to follow.

We believe the transaction will close by the end of 2006, following approval by
both companies' shareholders as well as customary closing conditions and
regulatory approvals. Given the complementary nature of our businesses, we
expect to realize the benefits of this transaction quickly and efficiently
following the transaction's close.

Until then, Thermo and Fisher remain separate companies. For us at Thermo, it
must be business as usual - continuing to focus on our customers and executing
against our strategic and





operating plan. Communications with Fisher regarding our business and marketing
plans, customer information, pricing and other sensitive information must be
avoided.

In the meantime, please refer to the Thermo Fisher Scientific News section on
Thermo.net, where we will post developments and progress throughout the approval
process.

As individual companies, Thermo and Fisher have achieved strong financial
performance through organic growth and operating margin expansion. By uniting
our complementary capabilities, we are creating a global leader with product
breadth, global reach and operational expertise to drive significant value for
our shareholders, customers and employees. I look forward to talking to you more
about this exciting combination in the coming weeks.

As we move forward to combine Thermo and Fisher, I ask you - in the spirit of
PPI - to continue your hard work and dedication to our customers. Our focus has
been on creating the most comprehensive, innovative solutions for our customers;
this combination with Fisher enables us to continue our momentum.


Regards,

Marijn E. Dekkers
President & CEO

        19,500 employees are committed to maintaining high standards and to
        helping to make customers more efficient and effective at what they do.

2.      WHY ARE THERMO AND FISHER COMBINING?

        This combination will create the leading provider of laboratory products
        and services in the high-growth life, laboratory and health sciences
        industry. By combining Thermo and Fisher's complementary technology
        leadership positions in instrumentation, life science consumables,
        software and services, the combined company will be uniquely positioned
        to provide integrated, end-to-end technical solutions to its customers
        worldwide. The combined company will have an industry leading global
        sales and service organization. Our customers will benefit from a
        partnership that can provide end-to-end application solutions and has
        the scale and scope to develop breakthrough integrated workflow
        solutions to reduce their costs and increase efficiency.

3.      WHAT WILL THE NEW COMPANY BE CALLED?

        Upon close of the transaction, the combined company will be called
        Thermo Fisher Scientific and will be headquartered in Waltham, MA.
        Marijn E. Dekkers will serve as Thermo Fisher Scientific's president and
        chief executive officer and Paul M Meister, currently vice chairman of
        Fisher Scientific, will be chairman of the combined company.

4.      WHEN WILL THE COMBINATION TAKE EFFECT? HOW LONG WILL IT TAKE?

        The transaction is expected to close by the end of 2006. Until then,
        Thermo and Fisher remain separate companies. In the meantime, please
        refer to the Thermo Fisher News section on Thermo.net, where we will
        make every effort to post developments and progress throughout the
        approval process. We will add to these Frequently Asked Questions as you
        raise questions with your managers and local HR representatives

5.      WHAT CAN EMPLOYEES EXPECT IN THE INTERIM?

        It's business as usual - continuing to focus on our customers and
        executing our annual operating plan and strategic plan objectives.

6.      WILL THERMO'S OR FISHER'S EMPLOYEES BE LAID OFF AS A RESULT OF THE
        MERGER?

        We believe that this is a compelling combination. As in any combination,
        there will inevitably be some overlap, and we will work to minimize
        those effects through hiring limits and normal attrition. Over the
        long-term, we believe that our combination with Fisher will result in
        additional career development and advancement opportunities for you as
        we move forward and grow together.





7.      WHAT HAPPENS TO EACH COMPANY'S COMMERCIAL TEAMS?

        While it's premature to speculate about those specifics now, both
        companies recognize the importance of a strong commercial team. The
        combined company will have an industry leading global sales and service
        organization comprised of nearly 7,500 sales and marketing
        professionals, and we will take the appropriate steps to ensure that our
        customers continue to receive the superior levels of service that they
        have come to expect.

        The experiences and insights of Thermo's and Fisher's employees will
        play a central role in the continued development of the combined
        company. By leveraging the relationships established by each company's
        sales force and the combined company's broad product and service
        portfolio, we expect to enhance existing customer relationships and
        build new ones.

8.      HOW DO THE CULTURES OF THE TWO COMPANIES COMPARE?

        Both of our companies have a strong track record of successful
        integration, and we are confident we will be able to move forward
        quickly after closing to combine our operations and our corporate
        cultures to capture the full benefits of this combination for our
        customers, our shareowners and our employees. We share a vision of where
        the industry is headed, a commitment to world-class customer service,
        and a highly skilled, motivated workforce. We are excited about the
        tremendous opportunity to establish the course for this future together.

9.      WILL ANY FACILITIES BE SHUT DOWN OR SOLD?

        It is premature to discuss specifics now, but we are building an
        integration planning team that will begin working to address how we can
        best grow the combined company.

10.     WHAT HAPPENS TO EMPLOYEES' COMPENSATION AND BENEFITS PROGRAMS?

        Thermo and Fisher are committed to providing a competitive compensation
        and benefits package. We expect no major changes in the short-term. Our
        initial focus will be to understand the components of both companies'
        benefit offerings and work towards designing and implementing integrated
        benefits package.

11.     IS FISHER A LIFE SCIENCES COMPANY ? HOW DOES THIS AFFECT THERMO'S
        BUSINESSES THAT ADDRESS INDUSTRIAL MARKETS?

        We remain very committed to our Measurement and Control business, and
        our unique "lab to line" solutions offering for customers.
