Dear Fellow Stockholder:

    You are cordially invited to attend our Special Meeting of Stockholders to
be held at 9:00 a.m. (local time), on Saturday, January 29, 2000, at the Holiday
Inn, 172 North Main Street, Concord, New Hampshire 03301.

    At the Special Meeting you will be asked to consider and vote upon a
proposal to approve and adopt an Agreement and Plan of Merger dated as of
August 23, 1999 (the "Merger Agreement"), pursuant to which Heat Merger Corp., a
newly formed Delaware corporation and a wholly-owned subsidiary of Heat Holdings
Corp., a newly-formed Delaware corporation, will be merged with and into Aavid
(the "Merger"). If the Merger Agreement is approved and the Merger is
subsequently consummated, each outstanding share of Aavid Common Stock will be
canceled and converted automatically into the right to receive $25.50 in cash,
without interest. Heat Holdings Corp. was organized by Willis Stein & Partners,
a private equity investment firm, for the purpose of acquiring all the
outstanding shares of Aavid Common Stock. As a result of the Merger, Aavid will
become a privately held company controlled by Willis Stein & Partners.

    Your Board of Directors has reviewed and considered the terms and conditions
of the Merger Agreement, has determined that the Merger is in the best interests
of Aavid and its stockholders and has approved the Merger Agreement. Our
financial advisor, Hambrecht & Quist LLC, rendered to our Board of Directors a
written opinion dated August 22, 1999 to the effect that, as of such date and
based upon and subject to the matters stated in the opinion, the $25.50 per
share price to be received in the Merger by the holders of Aavid Common Stock
was fair, from a financial point of view, to such holders. Hambrecht & Quist's
written opinion is attached as APPENDIX B to the enclosed Proxy Statement and
you should read it carefully and in its entirety.

    YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" APPROVAL
OF THE MERGER AGREEMENT.

    Approval and adoption of the Merger Agreement requires the affirmative vote
of the holders of a majority of our issued and outstanding shares of Common
Stock. Each share of Aavid Common Stock is entitled to one vote on all matters
to come before the Special Meeting. The Aavid Common Stock constitutes the only
outstanding class of our capital stock.

    Certain of our directors and officers have agreed, among other things, to
vote their shares of Aavid Common Stock entitled to vote at the Special Meeting
(approximately 3.8% of the outstanding shares of Aavid Common Stock) in favor of
the proposal to approve and adopt the Merger Agreement.

    Attached to this letter you will find a formal Notice of Special Meeting and
a related Proxy Statement. The accompanying Proxy Statement provides you with
detailed information about the Special Meeting and the proposed Merger. If the
Merger Agreement is approved by the requisite holders of Aavid Common Stock, the
closing of the Merger will occur as soon after the Special Meeting as all of the
other conditions to closing the Merger are satisfied. Please give this material
your

careful attention You may also obtain more information about us from documents
we have filed with the Securities and Exchange Commission.

    We look forward to greeting personally those stockholders who are able to be
present at the meeting; however, whether or not you plan to be with us at the
meeting, it is important that your shares be represented at the meeting.
Returning your proxy card as soon as possible will ensure your vote is counted
at the meeting, whether or not you plan to attend. YOUR VOTE IS IMPORTANT
REGARDLESS OF THE NUMBER OF SHARES OF AAVID COMMON STOCK YOU OWN. A FAILURE TO
VOTE WILL COUNT AS A VOTE AGAINST THE MERGER AGREEMENT. ACCORDINGLY, YOU ARE
REQUESTED TO PROMPTLY COMPLETE, SIGN AND DATE THE ENCLOSED PROXY CARD AND RETURN
IT IN THE ENVELOPE PROVIDED, WHETHER OR NOT YOU PLAN TO ATTEND. THIS WILL NOT
PREVENT YOUR FROM VOTING YOUR SHARES IN PERSON IF YOU SUBSEQUENTLY CHOOSE TO
ATTEND.

    Thank you for your cooperation.

                                          Very truly yours,

                                          /s/ Ronald Borelli

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: WHAT WILL HAPPEN IN THE MERGER?

A: Upon completion of the Merger, MergerCo will be merged with and into Aavid
    and the holders of Aavid Common Stock, other than those stockholders who
    exercise and perfect their dissenters' appraisal rights, will receive a cash
    payment of $25.50 for each of their outstanding shares of Aavid Common
    Stock.

Q: WHO WILL OWN AAVID AFTER THE MERGER?

A: After the Merger, Aavid will be a privately held company owned by Willis
    Stein and certain other institutional investors.

Q: WHY IS AAVID PROPOSING THE MERGER?

A: Aavid is proposing the Merger because the Aavid Board believes that the
    Merger is a more desirable alternative than continuing to operate Aavid as a
    public company. In particular, the Aavid Board considered the risks of
    continuing to operate Aavid as a public company and the opportunity for
    Aavid's stockholders to achieve liquidity with respect to their investment
    in Aavid at a price that the Aavid Board, based in part on consultation with
    its financial advisor Hambrecht & Quist, believes is fair. To review the
    background and reasons for the Merger in greater detail, see pages 32
    through 45.

Q: WHY IS THE AAVID BOARD RECOMMENDING THAT I VOTE FOR THE MERGER AGREEMENT?

A: In the opinion of the Aavid Board, the terms and provisions of the Merger
    Agreement and the Merger are fair to and in the best interests of Aavid and
    its stockholders. To review the background and reasons for the Merger in
    greater detail, see pages 32 to 45.

Q: WHAT WILL I RECEIVE IN THE MERGER?

A. If the Merger is completed, you will receive $25.50 in cash, without
    interest, for each share of Aavid Common Stock that you own. This is the
    "cash merger consideration." For example, if you own 100 shares of Aavid
    Common Stock, upon completion of the Merger you will receive $2,550.00 in
    cash.

Q: IF THE MERGER IS COMPLETED, WHEN CAN I EXPECT TO RECEIVE THE CASH MERGER
    CONSIDERATION FOR MY SHARES?

A: Promptly after the Merger is completed, Aavid will send you detailed
    instructions regarding the surrender of your Aavid Common Stock
    certificates. You should not send your Aavid Common Stock certificates to
    Aavid or anyone else until you receive these instructions. Aavid will send
    payment of the cash merger consideration to you as promptly as practicable
    following its receipt of your stock certificates and other required
    documents.

Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A: We expect the Merger to be completed in January 2000.

Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

A: The receipt of the cash merger consideration by you will be a taxable
    transaction for federal income tax purposes. You will recognize a gain or
    loss in an amount equal to the difference between the adjusted tax basis of
    your Aavid Common Stock and the amount of cash you receive in the Merger. If
    your Aavid Common Stock is a capital asset, your gain or loss will generally
    be long-term gain or loss if your deemed holding period for your Aavid
    Common Stock is more than one year at the effective time of the Merger. To
    review the tax consequences to you in greater detail, see page 52. As with
    any transaction of this type, your tax consequences will depend on

                                       4

    your personal situation. You should consult your tax advisors for a full
    understanding of the tax consequences of the Merger to you.

Q: WHAT AM I BEING ASKED TO VOTE ON?

A: You are being asked to approve the Merger Agreement, which provides, among
    other things, for the acquisition of Aavid by Willis Stein. After the

    THROUGHOUT THIS PROXY STATEMENT WHEN WE REFER TO THE "MERGER," WE MEAN THE
MERGER OF HEAT MERGER CORP., A WHOLLY-OWNED SUBSIDIARY OF HEAT HOLDINGS CORP.,
WHICH IS CONTROLLED BY WILLIS STEIN, WITH AND INTO AAVID, AS DESCRIBED IN THE
MERGER AGREEMENT. FROM AND AFTER THE CONSUMMATION OF THE MERGER, AAVID WILL BE A
WHOLLY-OWNED SUBSIDIARY OF HOLDINGS AND WILL NO LONGER BE AN INDEPENDENTLY-OWNED
ENTITY. THROUGHOUT THIS PROXY STATEMENT WHEN WE REFER TO "AAVID," "WE," "US" OR
"OUR" OR WORDS OF LIKE IMPORT, WE ARE REFERRING TO AAVID THERMAL
TECHNOLOGIES, INC. AND ITS SUBSIDIARIES, INCLUDING THE SUBSIDIARIES CONSTITUTING
THE THERMALLOY DIVISION ACQUIRED FROM BOWTHORPE PLC ON OCTOBER 21, 1999.

THE COMPANIES (Page 18)

    AAVID THERMAL TECHNOLOGIES, INC.  We are the leading global provider of
thermal management solutions for electronic products and the leading developer
and marketer of computational fluid dynamics (CFD) software. Each of these
businesses has an established reputation for high product quality, service
excellence and engineering innovation in its market. We design, manufacture and
distribute on a worldwide basis thermal management products that dissipate
unwanted heat, which can degrade system performance and reliability, from
microprocessors and industrial electronics products. Our products, which include
heat sinks, interface materials and attachment accessories, fans, heat spreaders
and liquid cooling and phase change devices that we configure to meet
customer-specific needs, conduct, convect and radiate away unwanted heat. CFD
software is used in complex computer-generated modeling of fluid flows, heat and
mass transfer and chemical reactions. Our CFD software is used in a variety of
industries, including the automotive, aerospace, chemical processing, power
generation, material processing, electronics and HVAC industries.

    We believe the demand for thermal management products and CFD software is
growing. The increase in unwanted heat generated by electronic and other
products is primarily a result of more powerful semiconductors and the growing
number of semiconductors being used in individual products. The growing demand
for our thermal management products is driven by the need to dissipate the
increasing amount of heat generated by electronic products, as well as strong
unit growth. The increase in unwanted heat requires more complex thermal
solutions, which in turn is driving the trend among electronics manufacturers to
outsource development of thermal management solutions. The demand for our CFD
software is driven by our customers' needs to reduce product development costs,
minimize the time-to-market for their new products and improve product
performance.

    Our thermal management products are used in a wide variety and growing
number of computer and networking and industrial electronics applications,
including computer systems (desktops, laptops, disk drives, printers and
peripheral cards), network devices (servers, routers, set top boxes and local
area networks), telecommunications equipment (wireless base stations, satellite
stations and PBXs), instrumentation (semiconductor test equipment, medical
equipment and power supplies), transportation and motor drives (braking and
traction systems) and consumer electronics (stereo systems and video games). Our
CFD software is used for a variety of computer-based analyses, including the
design of electronic components and systems, automotive design, combustion
systems modeling and process plant troubleshooting. We have longstanding
relationships with a highly diversified base of more than 3,500 national and
international customers, including original equipment manufacturers (commonly
referred

                                       8

to as OEMs), electronics distributors and contract manufacturers. Our customers
include Acer, Apple, Arrow, AT&T, Cisco Systems, Compaq Computer,
DaimlerChrysler, Dell, Dow Chemical, Ericsson, Ford, Fujitsu, General Electric,
Harmon-Kardon, Hewlett-Packard, IBM, Intel, Lockheed Martin, Lucent, Motorola,
Nortel, Rockwell Automation, Rolls Royce, SCI Systems, Siemens, Silicon
Graphics, Solectron and Sun Microsystems.

    THERMAL MANAGEMENT INDUSTRY OVERVIEW.  In today's electronic environment,
microprocessors and their associated power supplies, hard drives, advanced video
chips and other peripheral devices, semiconductors, integrated circuits, motor
controls and telecommunications switches draw large amounts of power and,
consequently, must dissipate a significant amount of heat. Because these
electronic components can only operate efficiently in narrow temperature bands,
heat is an absolute constraint in electronic system design. The excessive heat
generated within a component not only degrades semiconductor and system
performance and reliability, but can also cause semiconductor and system
failure. The complexity of thermal management problems has been intensified by
the increasing amounts of heat to be dissipated, reductions in system size,
shorter time-to-market, shorter product life cycles and more demanding operating
environments of electronic products.

    We estimate that the worldwide electronic thermal management market, which
is comprised of all thermal management solutions for electronic products, is
approximately $4.1 billion. This market is divided between solutions that are
internally designed and produced by OEMs (I.E., "in-house" thermal solutions)
and those that are externally supplied by thermal management companies (I.E.,
"outsourced" thermal solutions). Based on our experience in the industry and
industry data, we estimate that the in-house thermal solutions market is
approximately $1.2 billion and the outsourced thermal solutions market is
approximately $2.9 billion, or 72% of the worldwide electronic thermal
management market. As thermal management problems become increasingly complex,
we believe that manufacturers will increasingly outsource their thermal
management design and production in order to focus on their core competencies.
We further believe that the market for the types of thermal management products
and services we offer in our existing geographic locations comprises
approximately 45% of the $2.9 billion outsourced thermal solutions market. We
believe that, through geographic and product expansion, we have a significant
opportunity to address a larger portion of the outsourced segment of this market
than we currently address.

    COMPUTATIONAL FLUID DYNAMICS SOFTWARE INDUSTRY OVERVIEW.  CFD software is
used in a wide range of industries for complex computer-based analysis of
engineering designs involving fluid flows, heat and mass transfer, chemical
reaction and other fluid flow phenomena. CFD software tools allow the analysis
and evaluation of design modifications without physical prototyping of each
design modification, thereby reducing engineering cost, improving product
performance, and decreasing time-to-market for new products. Specific uses of
CFD-based flow analysis include the design of electronic components and systems,
automotive design, combustion systems modeling and process plant
troubleshooting.

    Over the past decade, increases in computing power have made CFD-based
computer analysis of complex fluid flows feasible on computers that are readily
available to research and development and engineering departments. Development
of CFD software technology is expanding the market beyond its traditional user
base of Ph.D.-level engineers in corporate research and development centers to
the larger base of design engineers working in product development. Finally, CFD
software tools are part of the growing trend toward improved engineering
efficiency through computer-aided analysis and design by integrating CFD
software with geometric modeling and design.

    The CFD software market has been growing rapidly during the past decade.
Based on publicly available information from a number of our key competitors and
internal management estimates, we believe that in 1998 the developed market for
CFD software applications was approximately $100 million. We further believe
that this market has grown approximately 20% annually since 1992. Based on a
market study we conducted in connection with the acquisition of our CFD software

                                       9

business, we estimate that the potential market for CFD software products is
currently approximately $500 million.

    OUR COMPETITIVE STRENGTHS.  We believe that the following competitive
strengths have enabled us to become a worldwide leader in both the thermal
management market and the CFD software market:

    - TOTAL INTEGRATED SOLUTIONS PROVIDER. The increasing complexity of heat
      dissipation problems and the growing trend among manufacturers to
      outsource development of thermal management solutions has stimulated
      demand for total integrated solutions. We provide total integrated
      solutions by analyzing customers' thermal management problems at the
      device-, board- and system-level, designing, simulating and prototyping
      thermal management solutions and manufacturing, distributing and
      supporting these solutions worldwide.

    - VALUE-ADDED PARTNERING WITH OUR CUSTOMERS. We work closely with our
      customers to develop customized thermal management solutions. We believe
      that our close relationships with customers and their design and
      development teams, as well as our worldwide manufacturing capabilities,
      allow us to anticipate customers' needs and, through our engineering
      expertise and experience, provide quality product solutions more quickly
      than our competitors.

    - WORLDWIDE LOW COST MANUFACTURER. We have state-of-the-art manufacturing
      operations in the United States, Canada, Mexico, Europe and Asia,
      including China. As an increasing number of electronics systems are being
      manufactured outside the United States, our low cost foreign manufacturing
      operations enable us to supply products directly to our customers at their
      geographically dispersed manufacturing locations.

    - LEADERSHIP IN CFD TECHNOLOGY. We believe that we are the technology leader
      in CFD software. As a result of our technological leadership, we develop
      software that enables our customers to generate the increasingly complex
      computer models they demand for more cost-efficient product design. This
      factor, as well as the relative ease-of-use and predictive accuracy of our
      CFD software, are of primary importance to our customers.

    - RECURRING REVENUES FROM SOFTWARE BUSINESS. Our CFD software business is
      characterized by high customer retention and recurring revenues. In recent
      years, approximately 80% of our annual software license revenue was
      renewed in the following year. This is driven by the significant value
      added by our CFD software to the design process and the high cost of
      switching to a competitor's software.

    - EXPERIENCED MANAGEMENT TEAM. Our senior management team has extensive
      operating and marketing experience in the thermal management and CFD
      software markets. This management team has grown our business, both
      organically and through strategic acquisitions, and has been responsible
      for improving operating efficiencies. Bharatan R. Patel, our president and
      chief operating officer who will become our chief executive officer in
      January 2000 and who founded our CFD software business, has 27 years of
      experience in the area of fluid flows and thermal management, George P.
      Dannecker, president of our thermal management business, has 27 years of
      electronics industry experience and H. Ferit Boysan, president of our CFD
      software business, has 20 years of experience in the area of fluid flows
      and CFD software.

    OUR BUSINESS STRATEGY.  Our business strategy is to continue to be the
market leader in both the thermal management and CFD software markets. Key
elements of our strategy are to:

    - CAPITALIZE ON STRONG THERMAL MANAGEMENT INDUSTRY GROWTH. We believe that
      our existing thermal management markets will continue to experience strong
      growth. Growth will be driven by the need to dissipate the increasing
      amount of heat being generated by electronic products, as well as unit
      growth in these products. We believe our competitive strengths position us
      to capitalize on these growth trends.

                                       10

    - TAKE ADVANTAGE OF OUTSOURCING TREND. The increasing complexity of heat
      dissipation problems is driving a trend among manufacturers to outsource
      the development of thermal management solutions as they turn to companies
      with high levels of expertise in solving these problems. We intend to
      capitalize on this trend by leveraging our technical expertise in
      designing thermal management products and through continuing to partner
      with our customers in creating customized solutions.

    - EXPAND OUR ADDRESSED THERMAL MANAGEMENT MARKET. We believe we have
      significant opportunities to expand the portion of the outsourced thermal
      management market that we address. Our strategy is to expand into the $1.6
      billion part of the outsourced thermal management market that we do not
      currently serve by entering into geographic markets and introducing new
      products that complement our existing product offerings.

    - ACCELERATE GROWTH IN THE COMPUTATIONAL FLUID DYNAMICS SOFTWARE MARKET.
      Growth in the CFD software market will be driven by customers' needs to
      improve product performance, reduce product development costs and minimize
      the time-to-market for their new products, as well as by increasing
      applications for CFD software. We intend to grow our CFD software business
      through internal product development and possibly strategic acquisitions
      to leverage our core technological competence in the development of
      computerized design and simulation software. Our goal is to further expand
      this market beyond its traditional user base of Ph.D.-level engineers in
      corporate research and development centers to the larger base of design
      engineers by providing them easy-to-use industry-specific software.

    - PROVIDE TOTAL THERMAL MANAGEMENT SOLUTIONS ON A GLOBAL BASIS. We intend to
      continue capitalizing on our state-of-the-art worldwide manufacturing
      capabilities and to further leverage our expertise and technology to offer
      our customers a complete global solution to their thermal management
      problems. The increasing number of electronics systems manufactured
      outside of the United States has forced many electronics manufacturers to
      seek a highly integrated, worldwide provider of thermal solutions. We plan
      to continue to expand our quick-ramp, high-volume manufacturing and our
      design, sales and distribution activities globally as our customers
      continue to expand their operations overseas.

    - LEVERAGE OUR TECHNOLOGICAL LEADERSHIP. Our approximately 100 Ph.D.s and
      230 engineers focus on new technology initiatives as well as developing
      new and enhancing existing products, processes and materials to address
      the evolving needs of our customers. We seek to enhance our internal
      research and development activities through collaborations with our
      customers and third parties in order to gain access to, or to pursue the
      development of, new technologies for thermal management applications and
      CFD software.

    THERMALLOY ACQUISITION.  On October 21, 1999, we acquired our largest
competitor, Thermalloy, the thermal management division of Bowthorpe plc.
Thermalloy designs, manufactures and sells a wide variety of standard and
proprietary heat sinks and associated products, similar to those produced by our
thermal management business, within the computer and networking and industrial
electronics (including telecommunications) industries. This acquisition expanded
our worldwide manufacturing capabilities by providing us with facilities in
Dallas, Texas; Monterrey, Mexico; Corby and Swindon, England; Bologna, Italy;
and Malacca, Malaysia. In connection with this transaction, we also acquired
85.4% of Curamik Electronics GmbH, a German corporation that manufactures direct
bonded copper ceramic substrates that are used in the power semiconductor and
other industrial electronics industries. The total purchase price for Thermalloy
(including Curamik) was $82.7 million, including transaction costs. The
Thermalloy division, including Curamik, had revenues of approximately
$102.3 million for the year ended December 31, 1998 and $74.7 million for the
nine months ended September 30, 1999. We believe that the acquisition of
Thermalloy will create significant opportunities to realize cost savings through
plant closings, the elimination of duplicative selling, general and
administrative functions and the reduction of unnecessary corporate expenses.

    Our Board of Directors approved the Merger Agreement based on its
consideration of a number of factors, including:

    - the future prospects of Aavid as an independent company and possible
      alternatives to the proposed Merger;

    - the financial terms of the Merger;

    - the opinion of the Aavid Board's financial advisor that the cash merger
      consideration was fair from a financial point of view to the Aavid
      stockholders as of the date of that opinion; and

    - the likelihood that the transaction would be consummated.

OPINION OF AAVID'S FINANCIAL ADVISOR (Page 45)

    Hambrecht & Quist LLC, a nationally recognized investment banking firm that
served as financial advisor to the Aavid Board, has rendered a written opinion
dated as of August 22, 1999 to the Aavid Board that, as of the date of the
opinion, and based on the assumptions and subject to the limitations and
qualifications set forth therein, the cash merger consideration was fair, from a
financial point of view, to the holders of Aavid Common Stock. The full text of
the written opinion of Hambrecht & Quist dated August 22, 1999 is attached to
the back of this document as APPENDIX B, and should be read carefully in its
entirety. THE OPINION OF HAMBRECHT & QUIST IS DIRECTED TO THE AAVID BOARD AND
DOES NOT CONSTITUTE A RECOMMENDATION TO ANY AAVID STOCKHOLDER AS TO HOW SUCH
STOCKHOLDER SHOULD VOTE WITH RESPECT TO THE PROPOSED MERGER.

                                       13

DISSENTERS' APPRAISAL RIGHTS (Page 55)

    Under Delaware law, you have the right to dissent from the Merger and have
the appraised fair value of your shares of Aavid Common Stock paid to you in
cash. In order to dissent and receive the appraised fair value of your shares,
you must:

    - make a proper demand for appraisal in accordance with Delaware law as more
      fully described on pages 55 and 56;

    - hold your shares of Aavid Common Stock until the Merger is completed;

    - not vote in favor of the Merger (including by appointing a proxy to vote
      your shares in favor of the Merger); and

    - otherwise comply with Delaware law.

    Within ten days after the Merger, if you have satisfied the requirements of
Delaware law, the surviving corporation of the Merger will give you written
notice of the completion of the Merger. Within 120 days after the Merger, you,
any other dissenting stockholder or the surviving corporation may file a court
petition demanding a determination of the fair value of the shares of Aavid
Common Stock. If a petition for appraisal is timely filed, the court will
determine which stockholders are entitled to appraisal rights and the fair value
of the shares of Aavid Common Stock held by dissenting stockholders. You can
withdraw your demand for appraisal by delivering written notice to Aavid or to
the surviving corporation within 60 days after the Merger. If a petition for
appraisal isn't filed within 120 days after the Merger, your right to an
appraisal will cease and you'll be entitled to receive only the cash merger
consideration. APPENDIX C contains a copy of the applicable section of the
Delaware General Corporation Law and is incorporated by reference into this
Proxy Statement.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES (Page 52)

    The receipt of cash by an Aavid stockholder as a result of the Merger will
be a taxable transaction for federal income tax purposes and may also be taxable
under applicable state, local and foreign income and other tax laws. Each
holder's gain or loss per share of Aavid Common Stock will be equal to the
difference between $25.50 and the holder's tax basis in that particular share of
Aavid Common Stock. Such gain or loss generally will be a capital gain or loss
if the Aavid Common Stock is a capital asset in the hands of the stockholder and
generally will be a long-term capital gain or loss if the holding period exceeds
one year. However, because the tax consequences to each holder of Aavid Common
Stock will depend on each holder's particular circumstances and tax position,
you should consult your tax advisors as to the specific tax consequences of the
Merger to you.

TERMS OF THE MERGER AGREEMENT (Page 57)

    The Merger Agreement is attached to this Proxy Statement as APPENDIX A. You
are encouraged to read the Merger Agreement in its entirety. It is the legal
document that governs the Merger.

    GENERAL.  Upon consummation of the Merger, MergerCo will be merged with and
into Aavid and the Aavid stockholders will receive a cash payment of $25.50 for
each of their outstanding shares of Aavid Common Stock.

    CONDITIONS TO THE MERGER.  The completion of the Merger depends upon the
satisfaction of several conditions, including:

    - approval of the Merger Agreement by holders of a majority of the
      outstanding shares of Aavid Common Stock entitled to vote at the Special
      Meeting;

    - the waiting period applicable to the Merger under the Hart-Scott-Rodino
      Antitrust Improvements Act of 1976 having expired or been terminated;

                                       14

    - no judgment, injunction, order or decree and no provision of any law or
      regulation prohibits the completion of the Merger; and

    - all actions by or filings with any governmental body necessary to permit
      completion of the Merger having been taken or made.

    In addition, Holdings has the right not to consummate the Merger if:

    - we have not performed in all material respects the obligations that we are
      required under the Merger Agreement to perform prior to the effective time
      of the Merger;

    - our representations and warranties in the Merger Agreement that are
      qualified by "Material Adverse Effect" or similar terms are not true and
      correct in all respects as of the date of the Merger Agreement and as of
      the closing date of the Merger; or

    - our representations and warranties in the Merger Agreement that are not
      qualified by "Material Adverse Effect" or similar terms are not true and
      correct in all material respects as of the date of the Merger Agreement
      and as of the closing date of the Merger.

    Each party may, at its option, waive the satisfaction of any condition to
its obligations under the Merger Agreement. We cannot be certain when, or if,
the conditions to the Merger will be met. EVEN IF THE AAVID STOCKHOLDERS APPROVE
THE MERGER, THERE CAN BE NO ASSURANCE THAT THE MERGER WILL BE CONSUMMATED.

    OTHER ACQUISITION PROPOSALS.  Generally, we and our affiliates are
prohibited from initiating or soliciting, and are prohibited from participating
in discussions regarding, any proposal from a third party with respect to a
merger, consolidation, sale or similar transaction involving Aavid. We may,
under certain specified circumstances, take certain actions in connection with
unsolicited acquisition proposals.

    TERMINATION.  Either Aavid or Holdings may terminate the Merger Agreement
under certain circumstances, including if:

    - we, MergerCo and Holdings consent in writing;

    - the Aavid stockholders do not approve the Merger;

    - legal restraints or prohibitions prevent the consummation of the Merger;
      or

    - if the Merger has not been completed by March 31, 2000.

    In addition, we may terminate the Merger Agreement if our Board of Directors
determines in good faith, after reviewing the advice of its financial advisor,
that an acquisition proposal from a third party that is reasonably capable of
being financed is more favorable to the Aavid stockholders than the Merger, we
have complied with certain notice obligations, we pay Holdings a termination fee
of $8.3 million and we enter into a definitive agreement to complete the more
favorable acquisition proposal.

    Holdings may also terminate the Merger Agreement:

    - if our Board of Directors withdraws or materially modifies its approval of
      the Merger or its recommendation of the Merger to the Aavid stockholders
      or fails, as a result of the exercise of its fiduciary duties, to take
      action required to be taken by the Merger Agreement; or

    - if certain other conditions exist, including:

       - an event occurs, or a condition that existed on the date of the Merger
         Agreement worsens, which event or condition, by itself or together with
         other events or conditions, has had or could reasonably be expected to
         have a material adverse effect on our business, operations,

                                       15

         prospects (excluding the prospects of our industry or the economy as a
         whole), financial condition or assets; or

       - another person makes a tender or exchange offer for more than 30% of
         the Aavid Common Stock at a price greater than $25.50 per share; or any
         person or group acquires beneficial ownership or the right to acquire
         beneficial ownership of more than 30% of the Aavid Common Stock, except
         as disclosed in Schedules 13D or 13G filed with the Securities and
         Exchange Commission before August 24, 1999 or for arbitrage purposes;
         or any person or group that had disclosed beneficial ownership of 5% or
         more of the Aavid Common Stock prior to August 24, 1999 acquires
         beneficial ownership, or the right to acquire beneficial ownership, of
         an additional 10% or more of the Aavid Common Stock; or any person or
         group enters into an agreement in principle or a definitive agreement
         regarding a merger, consolidation or other business combination with
         us.

    FEES AND EXPENSES.  Generally, Aavid, on the one hand, and Holdings and
MergerCo, on the other hand, will pay their own fees, costs and expenses
incurred in connection with the Merger Agreement and the transactions
contemplated thereby. However, we will pay MergerCo "liquidated damages" of
$8.3 million under certain circumstances, including if:

    - Holdings terminates the Merger Agreement because our Board of Directors
      has withdrawn or materially modified its approval of the Merger or its
      recommendation of the Merger to the Aavid stockholders or has failed, as a
      result of the exercise of its fiduciary duties, to take action required to
      be taken by the Merger Agreement; or

    - we terminate the Merger Agreement because our Board of Directors has
      determined in good faith, after reviewing the advice of its financial
      advisor, that an acquisition proposal from a third party that is
      reasonably capable of being financed is more favorable to the Aavid
      stockholders than the Merger and we are entering into a definitive
      agreement to complete the more favorable acquisition proposal.

    STOCK OPTIONS AND WARRANTS.  Generally, each option to purchase shares of
Aavid Common Stock will become fully vested and exercisable immediately prior to
the Merger. Holders of options and warrants outstanding immediately prior to the
effective time of the Merger will receive cash for such options and warrants
based on the number of shares of Aavid Common Stock underlying the options or
warrants, as the case may be, to be cashed out and the difference between the
applicable per share exercise price of such options or warrants and the cash
merger consideration of $25.50.

WILLIS STEIN'S SOURCE OF FUNDS FOR THE MERGER CONSIDERATION

    In connection with the Merger Agreement, Willis Stein & Partners II, L.P.
delivered to us a commitment letter indicating that it is willing, subject to
the terms and conditions set forth in the commitment letter, to provide up to
$146 million of equity financing to consummate the Merger through the purchase
of equity securities of Holdings. In addition, Holdings delivered to us a
commitment letter from CIBC World Markets Corp. indicating that CIBC is willing,
on the terms and subject to the conditions set forth in the commitment letter,
to provide up to $123 million of debt financing to consummate the Merger.
Holdings will use the proceeds of this equity and debt financing to pay the
merger consideration. Holdings and MergerCo represented to us that this
financing is adequate to pay the merger consideration and related transaction
expenses.

WILLIS STEIN'S PLANS FOR AAVID FOLLOWING THE MERGER

    Willis Stein has advised us that it currently intends to grow our business
and that it has no present plans or proposals that would result in an
extraordinary corporate transaction involving us or our businesses, such as a
merger, sale of a division or relocation of operations.

                                       16

INTERESTS OF OUR OFFICERS AND DIRECTORS IN THE MERGER (Page 53)

    Our directors and executive officers, as well as several other members of
our senior management, have interests in the transaction as employees or
directors that are different from, or in addition to, your interests as
stockholders.

    STOCK OPTIONS.  Aavid previously granted to all outside directors, executive
officers and other senior management options to purchase shares of Aavid Common
Stock. Under the terms of the plans pursuant to which these options were issued,
all the options will vest in full and become exercisable in connection with the
consummation of the Merger. The Merger Agreement provides that all options to
purchase shares of Aavid Common Stock will, at the time the Merger is completed,
convert into the right to receive cash equal to the product of the number of
shares subject to such option times the excess, if any, of $25.50 per share over
the exercise price for such options. Our executive officers and directors will
receive an aggregate of $10.5 million from the cash-out of their options in the
Merger.

    EMPLOYMENT AGREEMENTS AND OTHER ARRANGEMENTS.  Aavid previously entered into
employment agreements with all of its executive officers. If, following the
Merger, the employment of any such individual terminates under certain
circumstances, we will be required to pay to such terminated individual a
severance payment equal to such individual's base salary for a specified period
of time and, in certain circumstances, certain other benefits. If following the
Merger the employment of all of our executive officers terminates under
circumstances requiring the payment of severance, we would be obligated to pay
them an aggregate of approximately $1,500,000 (excluding payments to
Mr. Borelli) and to continue to provide some of these officers with benefits for
up to two years. Mr. Borelli has determined to step down as our Chief Executive
Officer when his employment agreement expires on December 31, 1999, whether or
not the Merger has been consummated, and will therefore not be entitled to any
severance payments. Mr. Borelli will remain as Chairman of the Board and
Bharatan Patel, our President and Chief Operating Officer, will become our Chief
Executive Officer.

    INDEMNITY AND INSURANCE.  As described in "The Merger
Agreement--Indemnification of Officers and Directors," we and Holdings have
agreed that the surviving corporation will indemnify our officers and directors,
for at least six years after the Merger, against all damages and expenses they
may incur relating to their service as directors and/or officers, including
matters arising out of the Merger. This indemnification is subject to customary
conditions.

    EQUITY INTERESTS FOLLOWING THE MERGER.  Willis Stein has advised us that it
typically makes available, to management and key employees of its portfolio
companies, up to 10% of the fully-diluted common equity of the investment
vehicle portfolio company and the opportunity to co-invest in the common equity
and any preferred stock of the investment vehicle portfolio company on the same
economic terms as Willis Stein. The common equity made available to management
and key employees generally does not have any value until Willis Stein's
preferred stock investment is returned. Our management and key employees have
not had any discussions with Willis Stein concerning any such investment by
them, and no agreements, arrangements or understandings have been reached
between Willis Stein and our management and key employees in this regard.

    The Aavid Board knew about these additional interests and considered them
when it approved the Merger.

GOVERNMENTAL APPROVALS NECESSARY FOR THE MERGER TO OCCUR (Page 52)

    The Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
prohibits us from completing the Merger until we furnish certain information to
the Antitrust Division of the United States Department of Justice and the United
States Federal Trade Commission, and the required waiting period has expired or
been terminated. We, along with Willis Stein, made the required filings with the
Antitrust Division and the Federal Trade Commission on October 27, 1999. The
antitrust waiting period was terminated on November 5, 1999.

                              RECENT DEVELOPMENTS

ACQUISITION OF THERMALLOY DIVISION

    Our strategy is to capitalize on the two principal trends in the electronics
industry: first, the trend to develop products which incorporate microprocessors
and semiconductors with increasingly complex thermal dissipation problems, and
second, the trend to outsource development of thermal management solution. Key
elements of our strategy include providing "total solutions" capability for
thermal management globally and expanding our quick ramp, high-volume
manufacturing and our design, sales and distribution activities both
domestically and overseas. To further our strategy, we acquired the Thermalloy
Division of Bowthorpe plc in October 1999. The Thermalloy Division's business is
substantially similar to our thermal management products business. As part of
the acquisition from Bowthorpe, we also acquired 65.2%, representing Bowthorpe's
entire shareholding, of Curamik Electronics GmbH, a German corporation which
manufactures direct bonded copper substrates used in the packaging and cooling
of high power electronic devices. The total purchase price was $80.0 million
(including estimated transaction costs of $1.5 million), and is subject to
further adjustment based on changes in the value of the Thermalloy Division's
inventory between December 31, 1998 and July 31, 1999. The purchase price paid
at closing includes an estimate of the inventory related purchase price
adjustment. In a separate transaction, we acquired an additional 20.2% of
Curamik from its other stockholders for $2.7 million, increasing our ownership
of Curamik to 85.4%. The Company used $12.6 million of its cash on hand and
$84.3 million of borrowings under its new credit facility described below to pay
the purchase price for the Thermalloy Division, purchase the additional Curamik
shares, repay $12.6 million of outstanding debt and pay estimated transaction
costs. The Company paid $3.5 million of the $80.0 million purchase price into
escrow pending receipt of the necessary Malaysian governmental approvals of the
transfer of the Thermalloy Division's Malaysian operations to Aavid.

    The Thermalloy Division designs, manufactures and sells a wide range of
standard and proprietary heatsinks and associated products for the cooling of
semiconductors, power hybrid circuits, high power electronics and other
electronic devices, primarily within the aerospace, automotive, computer,
construction and telecommunications industries. The Thermalloy Division, like
us, possesses both the engineering and production capability to design and
manufacture solutions to meet customers' thermal management requirements. The
Thermalloy Division has manufacturing facilities in Dallas, Texas; Monterrey,
Mexico; Swindon, England; Corby, England; Bologna, Italy; Hong Kong; and
Malaysia; engineering staff in the United States and Europe and additional sales
staff in France, Germany, Japan and Singapore. The Thermalloy Division,
including Curamik, had revenues of approximately $102.3 million for the year
ended December 31, 1998 and $74.7 million for the nine months ended
September 30, 1999. Please see "Selected Historical Financial Data--Thermalloy
Division" below for more financial information about the Thermalloy Division.

    The Thermalloy Division's business has benefitted from the same industry
trends as we have. Increased power use, functionality and continuing
miniaturization of electronics have increased demand for thermal management
products and solutions. At the same time, more original equipment manufacturers,
commonly referred to as OEMs, have moved their manufacturing operations overseas
to lower cost areas, such as Asia and Latin America, and have increased the
outsourcing of their thermal management design operations to companies which
offer higher specialization, greater expertise and shorter development lead
times.

    Our future success will depend, in part, on our ability to fully integrate
the operations and management of the Thermalloy Division. A successful
integration requires, among other things, the integration of Thermalloy's
product offerings and technology into ours and the coordination of their sales
and marketing and financial reporting efforts with ours. We cannot assure you
that we will

                                       18

accomplish the integration smoothly or successfully. We cannot assure you that
we will realize the anticipated benefits of the Thermalloy Division acquisition.
The success of the integration will require the dedication of management and
other personnel resources which may temporarily distract their attention from
our day-to-day business.

    We have recently experienced substantial growth in our thermal management
products business and have significantly expanded our operations through
manufacturing capacity additions, the acquisition of the Thermalloy Division and
geographic expansion. We intend to continue to increase our thermal products and
software businesses overseas, expand the products and services we offer, and
make selective acquisitions. This growth and expansion has placed, and will
continue to place, a significant strain on our production, technical, financial
and other management resources. To manage growth effectively, we must maintain a
high level of manufacturing quality, efficiency, delivery and performance and
must continue to enhance our operational, financial and management systems, and
attract, train, motivate and manage our employees. We may not be able to
effectively manage this expansion, and any failure to do so could have a
material adverse effect on our business and financial condition.

    In connection with the closing of the acquisition of the Thermalloy
Division, we entered into a $100 million revolving credit and term loan facility
with Canadian Imperial Bank of Commerce, as Administrative Agent, and certain
other lenders (the "Credit Facility"). The Credit Facility consists of an
$80 million term loan facility (the "Term Facility") and a $20 million revolving
credit facility, including a $2 million letter of credit subfacility (the
"Revolving Facility"). The Term Facility, all of which was borrowed on
October 21, 1999 to pay the purchase price for the Thermalloy Division and pay
transaction costs, matures on September 30, 2004, and will be amortized in 19
consecutive quarterly installments, commencing March 31, 2000, as follows: four
quarterly payments of $2 million each; four quarterly payments of $3 million
each; four quarterly payments of $4 million each; four quarterly payments of
$5 million each; and three quarterly payments of $8 million each. The Revolving
Facility matures on September 30, 2004. The Credit Facility bears interest at a
rate equal to, at our option, either (1) in the case of Eurodollar loans, the
sum of (x) the interest rate in the London interbank market for loans in an
amount substantially equal to the amount of borrowing and for the period of
borrowing selected by us and (y) a margin of between one and one-half percent
and two percent (depending on our consolidated leverage ratio (as defined in the
credit agreement)) or (2) the sum of (A) the higher of (x) Canadian Imperial
Bank of Commerce's prime or base rate or (y) one-half percent plus the latest
overnight federal funds rate plus (y) a margin of between one quarter percent
and three quarters percent (depending on our consolidated leverage ratio). The
Credit Facility may be prepaid at any time in whole or in part without penalty,
and must be prepaid to the extent of certain equity or asset sales.

    The Credit Facility limits our ability to incur debt, to sell or dispose of
assets, to create or incur liens, to make additional acquisitions, to pay
dividends, to purchase or redeem our stock and to merge or consolidate with any
other person other than MergerCo. In addition, the Credit Facility requires that
we meet certain financial ratios, and provides the banks with the right to
require the payment of all amounts outstanding under the facility, and to
terminate all commitments thereunder, if there is a change in control of Aavid
other than as contemplated by the Merger Agreement. The Credit Facility is
guaranteed by all of our domestic subsidiaries and secured by our assets
(including the assets and stock of our subsidiaries).

    The Merger Agreement provided that the merger consideration would be $25.50
per share only if we acquired the Thermalloy Division; otherwise the merger
consideration would be $24.50 per share. Because we completed that acquisition
of the Thermalloy Division, the merger consideration will be $25.50 per share.

                                       19

STOCKHOLDER LITIGATION

    Following the public announcement of the Merger, lawsuits were filed against
us, Willis Stein, our directors and one former director in the Court of Chancery
of the State of Delaware by some of our stockholders. The complaints allege,
among other things, that our directors have breached their fiduciary duties and
seek to enjoin, preliminarily and permanently, the Merger and also seek
compensatory damages. The stockholder plaintiffs, on behalf of our public
stockholders, also seek class action certification for their lawsuits. We
believe the actions to be without merit and intend to contest the actions
vigorously.

SELECTED PRO FORMA FINANCIAL DATA

    On October 21, 1999, we completed the acquisition of the Thermalloy Division
from Bowthorpe plc. The total purchase price was $80.0 million (including
estimated transaction costs of $1.5 million), and is subject to further
adjustment based on changes in the value of the Thermalloy Division's inventory
between December 31, 1998 and July 31, 1999. The purchase price paid at closing
includes an estimate of the inventory related purchase price adjustment. We paid
$3.5 million of the $80.0 million purchase price into escrow pending receipt of
the necessary Malaysian governmental approvals of the transfer of the Thermalloy
Division's Malaysian operations to us. We expect to receive these approvals in
the first half of 2000. In addition, on October 28, 1999 we purchased an
additional 20.2% of Curamik from the two minority shareholders of Curamik for
approximately $2.7 million, thereby increasing our ownership of Curamik to
85.4%. We used $12.6 million of our cash on hand and $84.3 million of borrowings
under our new credit facility described above under "Acquisition of Thermalloy
Division" to pay the purchase price for the Thermalloy Division, purchase the
additional Curamik shares, repay $12.6 million of outstanding debt and pay
estimated transaction costs.

    The following unaudited pro forma financial data gives effect to our
acquisition of the Thermalloy Division and the additional 20.2% of Curamik,
which will be accounted for by the purchase method. The pro forma unaudited
balance sheet as of October 2, 1999 gives effect to the acquisition of the
Thermalloy Division and the additional Curamik shares, including the incurrence
of $84.3 million of indebtedness to finance the acquisition (including the
additional Curamik shares), to repay our existing outstanding indebtedness and
to pay estimated transaction costs, as if the acquisition had occurred on
October 2, 1999, the last day of our fiscal quarter. The pro forma unaudited
statements of income for the year ended December 31, 1998 and the nine months
ended October 2, 1999 give effect to the acquisition of the Thermalloy Division
and the additional Curamik shares, including the incurrence of $84.3 million of
indebtedness to finance the acquisition (including the additional Curamik
shares), to repay our existing outstanding indebtedness and to pay estimated
transaction costs, as if the acquisition had occurred on January 1, 1998. In
combining the financial information of Aavid and the Thermalloy Division to
reflect the acquisition of the Thermalloy Division and the additional Curamik
shares, the financing of the acquisition and the accounting policies of Aavid,
certain reclassifications of historical financial data have been made. The pro
forma financial statements assume that we also acquired on October 21, 1999
(1) the Malaysian operations of the Thermalloy Division, which were actually
closed into escrow pending receipt of regulatory approvals, and (2) an
additional 20.2% of Curamik which we acquired from its minority shareholders on
October 28, 1999, thereby increasing our ownership interest in Curamik to 85.4%.

    The unaudited pro forma combined statements of income do not give pro forma
effect to anticipated cost savings resulting from the combination of Aavid and
the Thermalloy Division. The cost savings will primarily result from (1) the
closure of the two Aavid manufacturing facilities and a Thermalloy Division
manufacturing facility due to the elimination of duplicate operations, (2) a

                                       20

reduction of selling, general and administrative costs through elimination of
overlapping functions and (3) operating improvements such as purchasing
synergies, improved leverage of existing resources, implementation of best
practices or similar efficiencies. The pro forma financial statements do not
give effect to possible revenue reductions that may result from potential
customer dislocation and loss due to the Merger and plant closures.

    The information contained herein has been prepared utilizing a preliminary
purchase price allocation subject to refinement until pertinent information
related to the acquisition has been obtained. The pro forma adjustments
discussed herein are based on available information and assumptions that we
believe are reasonable. We believe that the final allocation of the Thermalloy
Division purchase price will not differ materially from the preliminary
estimated amounts. We estimate that the final purchase price allocation will be
completed once the final integration plan for the acquisition is completed. We
commenced the final integration plan for the acquisition promptly following the
closing and expect to substantially complete it no later than one year after the
closing.

    The following pro forma unaudited financial data should be read in
conjunction with the historical consolidated financial statements of Aavid and
the Thermalloy Division, including the respective notes thereto, which are
incorporated by reference in this Proxy Statement. Please see "Where You Can
Find More Information" for information about how you can obtain copies of these
financial statements.

    The unaudited pro forma financial data is presented for informational
purposes only and is not necessarily indicative of our operating results or
financial position that would have occurred had the acquisition of the
Thermalloy Division occurred at the dates indicated, nor is it necessarily
indicative of our future operating results or financial position following the
acquisition.

    Dallas facility, which is being made available to us on a rent free basis
    through 2008.

(i) Adjustment to write-off existing Thermalloy Division goodwill of $8,703.

    associated with the closure of certain offices and operations of the

    adjustment excludes the estimated severance and other costs associated with
    the closure of certain offices and operations of Aavid, which costs cannot
    be capitalized and must be expensed and are estimated to be approximately
    $1,500. These amounts are preliminary estimates of management. Management is
    currently in the process of finalizing their assessment of these costs and
    committing to a final integration plan, which is expected to be completed
    and communicated to employees as soon as possible, but in no event later
    than one year from the date of the Thermalloy Division acquisition. The
    exact amount and type of severance benefits to be received by each employee
    is unknown at this time. Once the nature of the actual severance benefits
    has been determined, actual severance liabilities arising from this
    restructuring may differ from the amount included within these pro forma
    financial statements.

(k) Adjustment to record the deferred tax liability on the write-up of assets
    which are not recognized for corporate income tax purposes.

(l) Adjustment to eliminate Thermalloy Division equity.

(m) Adjustment to record the decrease in depreciation resulting from the write
    down of fixed assets to fair value that occurred in purchase accounting, in
    the amounts of $480 in the year ended December 31, 1998 and $360 in the nine
    months ended October 2, 1999. These amounts assume an estimated remaining
    useful life of 4 years.

(n) Adjustment to record amortization of the prepaid rent asset discussed in
    (h) above. This asset is being amortized over the life of the lease,
    9 years, in the amounts of $654 for the year ended December 31, 1998 and
    $491 for the nine months ended October 2, 1999.

(o) Adjustment to record the straight line amortization on the excess of
    purchase price over the tangible and intangible assets acquired (goodwill),
    calculated on a straight line basis over 20 years as follows:

   The actual amortization recorded after consummation of the acquisition of the
    Thermalloy Division may differ from these amounts due to the full allocation
    of purchase price to assets and liabilities pursuant to Accounting
    Principles Board Opinion No. 16.

(p) Adjustment to eliminate management fees paid by Thermalloy to Bowthorpe plc
    in the amount of $1,484 for the year ended December 31, 1998 and $1,336 for
    the nine months ended September 30, 1999. This charge relates to management
    advice and consultation provided by Bowthorpe plc and does not consist of
    any direct expenses that would be incremental to Aavid under the
    combination. We believe that net sales and expenses would not have
    materially changed if Bowthorpe plc did not provide the management services.

1.  The unaudited pro forma combined statements of income do not give pro forma
    effect to anticipated cost savings resulting from the combination of Aavid
    and the Thermalloy Division, because these adjustments do not meet the
    factually supportable criteria of SEC regulations. These costs savings will
    primarily result from the closure of two Aavid manufacturing facilities and
    a Thermalloy Division manufacturing facility due to the elimination of
    duplicative operations, including, among other costs, the elimination of
    employee payroll and benefits and certain rental, office and other direct
    expenses. We also expect to reduce selling, general and administrative

    expenses at Thermalloy's U.S. corporate office by eliminating or combining

    follows:

   The anticipated cost savings and reductions as a result of the acquisition
    are based upon historical costs and actual savings achieved could differ
    materially. The cost savings do not give effect to possible revenue
    reductions that may result from potential customer dislocation and loss due
    to the Merger and plant closures. We also expect to achieve additional cost
    savings from taking certain other actions, the effect of which we are unable
    to quantify at this time, such as benefits resulting from operating
    improvements such as purchasing synergies, improved leverage of existing
    resources, implementation of best practices or similar efficiencies.

                              THE SPECIAL MEETING

GENERAL

    This Proxy Statement is being furnished to holders of Aavid Common Stock in
connection with the solicitation of proxies by and on behalf of the Aavid Board
for use at the Special Meeting of Stockholders to be held at 9:00 a.m. local
time, on Saturday, January 29, 2000, at the Holiday Inn, 172 North Main Street,
Concord, New Hampshire 03301, and at any adjournment or postponement thereof. We
are first mailing this Proxy Statement, the accompanying notice, proxy card and
letter on or about December 30, 1999 to all holders of Aavid Common Stock
entitled to notice of, and to vote at, the Special Meeting.

MATTERS TO BE CONSIDERED

    At the special stockholders' meeting, Aavid stockholders will consider and
vote on:

    - approval and adoption of the Merger Agreement; and

    - any other matters that may properly be brought before the Aavid
      stockholders' meeting or at any adjournment or postponement of the
      stockholders' meeting.

RECOMMENDATION OF THE AAVID BOARD

    The Aavid Board has unanimously approved the Merger Agreement and the
transactions contemplated by the Merger Agreement. The Aavid Board believes that
the Merger Agreement and the transactions contemplated by the Merger Agreement
are fair to and in the best interests of Aavid and its stockholders and
recommends that you and the other Aavid stockholders vote "FOR" approval and
adoption of the Merger Agreement. See "The Merger--Our Reasons for the Merger"
beginning on page 42.

RECORD DATE AND QUORUM REQUIREMENTS

    In accordance with Delaware law and Aavid's By-Laws, the Aavid Board has
fixed November 30, 1999 as the record date for determining the Aavid
stockholders entitled to notice of and to vote at the Special Meeting.
Accordingly, you are entitled to notice of and to vote at the meeting only if
you were a record holder of Aavid Common Stock at the close of business on that
date. At that time, there were 9,608,268 shares of Aavid Common Stock
outstanding. These shares were held by approximately 70 stockholders of record.

    In order to have a quorum that will permit us to conduct business at the
meeting, we need to have at least 4,804,135 shares of Aavid Common Stock,
representing a majority of the shares of Aavid Common Stock outstanding on the
record date, represented at the meeting, whether in person or by proxy.

    Shares of Aavid Common Stock represented in person at the meeting but not
voting, and shares of Aavid Common Stock for which we have received proxies but
with respect to which holders of those shares have abstained, will be counted as
present at the meeting for purposes of determining the presence or absence of a
quorum permitting us to conduct business at the meeting. Brokers who hold shares
of Aavid Common Stock in nominee or "street" name for customers who are the
beneficial owners of those shares cannot give a proxy to vote those shares
without specific instructions from those customers. Shares represented by
proxies returned by a broker holding shares in "street" name will be counted for
purposes of determining whether a quorum exists, even though those shares will
not be voted on the Merger without specific instructions from customers ("broker
non-votes").

    Certain of our directors and officers beneficially owning 360,565 shares of
outstanding Aavid Common Stock, or approximately 3.8% of the outstanding shares
of Aavid Common Stock on the record date, have agreed with Holdings to vote
their shares in favor of the Merger. These figures are calculated without
counting shares which could be acquired by exercising stock options because the

                                       29

shares underlying those options cannot be voted at the Special Meeting. In
addition, Willis Stein owns 2,000 shares of Aavid Common Stock.

STOCKHOLDERS ENTITLED TO VOTE AND VOTE REQUIRED

    The Merger cannot be completed without Aavid stockholder approval.

    Each share of Aavid Common Stock will have one vote for each matter properly
submitted at the Special Meeting. The affirmative vote, either in person or by
proxy, of a majority of the shares of Aavid Common Stock outstanding is required
in order to approve the Merger Agreement. These shares may be represented either
in person or by proxy. If you abstain from voting or if you do not submit a
proxy card and do not vote in person at the Special Meeting, your non-action
will have the effect of a vote against the Merger. Also, any broker non-vote
will have the effect of a vote against the Merger.

VOTING PROCEDURES

GENERAL

    Your vote is important. Because many stockholders cannot personally attend
the Special Meeting, it is necessary that a large number be represented by
proxy. If a stockholder of record does not submit a proxy or vote in person at
the Special Meeting, his or her shares will not be voted and the stockholder
will not be counted as present for determining the existence of a quorum.
Abstentions and broker non-votes will be included in determining the number of
shares present at the Special Meeting, but will not be counted in the tabulation
of votes on the Merger.

    We encourage you to vote and to vote promptly. Voting promptly may save
Aavid the expense of a second mailing.

STOCKHOLDERS OF RECORD

    If you are a stockholder of record, meaning that your shares and your stock
certificate(s) are registered in your name with Aavid and its transfer agent,
you may vote (1) by attending the Special Meeting or (2) by marking, signing,
dating and mailing the enclosed proxy card in the postage-paid envelope
provided.

    You may revoke your proxy at any time before the vote is taken at the
meeting by submitting a written notice of revocation to the corporate Secretary
of Aavid, by properly executing a later-dated proxy or by attending the meeting
and voting in person. Attendance at the Special Meeting without taking other
affirmative action as described in the prior sentence will not constitute a
revocation of a proxy. Written notices of revocation and other communications
concerning the revocation of a previously executed proxy should be addressed to:

                    Aavid Thermal Technologies, Inc.
                    One Eagle Square
                    Concord, New Hampshire 03301
                    Attention: Secretary

    You may also be represented by another person present at the meeting by
executing a proxy designating such person to act on your behalf. If you sign,
date and mail your proxy card without indicating how you want to vote, your vote
will be counted as a vote in favor of the Merger Agreement.

STOCKHOLDERS IN STREET NAME

    Different procedures may apply to shares held in a brokerage account and
therefore listed in the name of a broker or other intermediary. This practice is
also referred to as shares being held in "street name", rather than in the
stockholder's own name. A stockholder whose shares are held in street name
through an intermediary is referred to as the "beneficial owner" of the shares,
while the intermediary or stockholder of record is referred to as the "record
owner" of the shares. Shares held in street name

                                       30

are voted by the record owner rather than the beneficial owner. However, the
record owner usually is required to provide a means for the beneficial owner to
direct how the record owner is to vote the shares. This may include providing a
proxy card or instructions that may differ from the materials provided by Aavid
to its stockholders of record.

    If your shares are held in street name, you should follow whatever
instructions are provided by the record owner of your shares. The broker or
other intermediary serving as record owner of your shares, in its discretion,
may choose to provide a means for you to direct the voting of your shares by
telephone or over the Internet. If so, appropriate instructions may be set forth
on the enclosed proxy card, or the broker or other intermediary may choose to
provide separate instructions.

    If your shares are held in street name and you wish to vote such shares by
attending the Special Meeting in person, you will need to obtain a proxy from
the broker or other intermediary who is the stockholder of record having the
legal authority to vote your shares. Please note that, once a beneficial or
street name owner has submitted voting instructions, such instructions may be
changed or revoked only in accordance with the procedures of the broker or other
record owner of such shares, and then only in accordance with the procedures
applicable to stockholders of record as described above. If your shares are held
in street name, then to change or revoke your voting instructions you must
contact the broker or other intermediary who is the stockholder of record having
the legal authority to vote your shares.

VOTING OF PROXIES

    All shares represented by valid proxies that we receive as a result of this
solicitation (other than those proxies that are revoked before they are voted)
will be voted in the manner specified by you and the other Aavid stockholders.
If you do not specify how to vote your proxy, your shares will be voted "FOR"
the approval and adoption of the Merger Agreement. The Aavid Board is not
currently aware of any other matters that may be presented for action at the
meeting, but if other matters do properly come before the meeting, we intend
that shares represented by proxies solicited by the Aavid Board will be voted by
the named proxies in their discretion. However, proxies that are voted against
approval and adoption of the Merger Agreement will not be voted in favor of any
adjournment or postponement of the meeting proposed in order to solicit
additional proxies to approve and adopt the Merger Agreement.

    AAVID STOCKHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH THEIR PROXY
CARDS.

    BECAUSE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT REQUIRES THE
AFFIRMATIVE VOTE OF THE HOLDERS OF AT LEAST A MAJORITY OF THE SHARES OF AAVID
COMMON STOCK OUTSTANDING ON THE RECORD DATE, ABSTENTIONS, BROKER NON-VOTES AND
FAILING TO VOTE WILL HAVE THE SAME EFFECT AS VOTING AGAINST APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT. ACCORDINGLY, THE AAVID BOARD URGES YOU TO
DESIGNATE A PROXY TO VOTE YOUR SHARES.

SOLICITATION OF PROXIES

    We will bear the costs incidental to the solicitation and obtaining of
proxies, including the cost of reimbursing banks and brokers for forwarding
proxy materials. Proxies may be solicited, without extra compensation, by our
officers and employees by mail, telephone, telefax, personal interviews and
other methods of communication. Although we have no present plans to hire paid
solicitors to assist us in obtaining proxies, we may do so if we determine it
will be helpful in obtaining stockholder approval of the Merger. We will pay all
the fees and expenses of any firm engaged by us.

    STOCKHOLDERS ARE URGED TO COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY
IN THE ENVELOPE PROVIDED. IN ORDER TO AVOID UNNECESSARY EXPENSE, WE ASK YOUR
COOPERATION IN MAILING YOUR PROXY PROMPTLY, NO MATTER HOW LARGE OR SMALL YOUR
HOLDINGS MAY BE.

                                       31

                                   THE MERGER

    THE DESCRIPTION IN THIS PROXY STATEMENT OF THE MERGER AND THE PRINCIPAL
TERMS OF THE MERGER AGREEMENT IS SUBJECT TO, AND IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO, THE MERGER AGREEMENT, THE LEGAL DOCUMENT GOVERNING THE MERGER. WE
HAVE ATTACHED A COPY OF THE MERGER AGREEMENT TO THIS PROXY STATEMENT AS
APPENDIX A AND RECOMMEND THAT YOU READ IT CAREFULLY.

BACKGROUND OF THE MERGER

    We have, since becoming a publicly traded company in January 1996, looked to
expand our operations to enhance long-term stockholder value and meet our
customers' needs by considering potential strategic acquisitions and
combinations involving other thermal management product manufacturers and
computational fluid dynamics ("CFD") software providers, and have completed
several acquisitions and alliances. One of our strategies has been to obtain
greater value for Fluent, which we believed was being undervalued by the market
because of our thermal management products business. However, we could not
"spin-off" Fluent as a stand-alone company on a tax-free basis until
September 2000, and, in any case, we believed that Fluent, without additional
acquisitions, would be too small in the current market environment to succeed as
a stand-alone public company. Accordingly, we determined to try to expand Fluent
by acquisition. In pursuit of this strategy, we engaged Hambrecht & Quist LLC
("H&Q") in late March, 1999 to assist us in identifying software companies for
acquisition.

    Our strategy with respect to our thermal management product manufacturing
business has been to capitalize on the two principal trends in the electronics
industry: first, the trend to develop products which incorporate microprocessors
and semiconductors with increasingly complex thermal dissipation problems, and
second, the trend to outsource development of thermal management solutions. As
part of this strategy, we have focused on providing "total solutions" capability
for thermal management globally and expanding our quick ramp, high-volume
manufacturing and our design, sales and distribution activities both
domestically and overseas. As part of our effort to expand, in December 1998 and
January 1999 our senior management had several discussions with Bowthorpe plc, a
United Kingdom publicly-traded company, regarding a possible acquisition by
Aavid of Bowthorpe's Thermalloy Division, which also manufactures thermal
management products. Discussions were mutually terminated in January 1999
because of our concern about the Thermalloy Division's deterioration in
performance compared to the prior year and budget.

    In late February, 1999, a representative of CIBC World Markets and
Mr. Douglas Newhouse, one of our directors from October 1993 to June 1998,
during the course of a discussion about a transaction unrelated to Aavid,
discussed the possibility of selling Aavid. Mr. Newhouse is a founder, together
with M. William Macey, Jr., one of our directors, and William Selden, one of our
directors from October 1993 to October 1997, of Sterling Ventures Limited, which
led the recapitalization of Aavid in October 1993. Mr. Newhouse, although no
longer one of our directors, and the other Sterling principals continued to view
Aavid as a "portfolio company" because of Sterling Venture's role in the
recapitalization of Aavid and continued to have an interest in Aavid's future.
The principals of Sterling Ventures and other investors obtained through
Sterling's efforts, rather than Sterling Ventures itself, provided the equity
financing in the recapitalization. Following the discussion, the representative
of CIBC World Markets, which has acted as a financial advisor in prior
transactions to Willis Stein, Sterling Ventures and their portfolio companies,
contacted Willis Stein and arranged a meeting between Willis Stein and
Mr. Newhouse. On March 2, Mr. Newhouse, at his own initiative and without
authorization of the Aavid Board, met with Mr. Avy Stein, who was in New York on
other business, and other representatives of Willis Stein and representatives of
CIBC World Markets. The participants discussed the history of Aavid, its
business, publicly available financial information, industry dynamics and Willis
Stein's background.

    Willis Stein has advised us that on March 12, 1999, based on its review of
publicly available information about Aavid, it purchased 2,000 shares of Aavid
Common Stock at a price of $12.625.

                                       32

    In late March, 1999, a corporation ("Strategic Buyer 1") contacted us to
determine our interest in working together in some manner. On March 29, 1999,
Ronald Borelli, our Chairman and Chief Executive Officer, met with a
representative of Strategic Buyer 1 to discuss generally possible ways we could
work together, including a strategic partnering arrangement whereby Aavid and
Strategic Buyer 1 would work together to supply electronic cooling devices.

    On April 9, 1999, at the request of Willis Stein, Messrs. Borelli, Stephen
Eldred, our Chief Financial Officer, Macey, John Mitchell, our General Counsel,
and Bart Patel, our President, met with Mr. Stein and other representatives of
Willis Stein, and representatives of CIBC World Markets, advisors to Willis
Stein, at our corporate headquarters in Concord, New Hampshire. At the meeting,
the participants discussed Aavid's operations and historical results, and Willis
Stein indicated that it was interested in exploring a possible acquisition of
Aavid, and offered to provide a preliminary pricing analysis.

    On April 13, 1999, we entered into a standard form of confidentiality
agreement with Willis Stein, which included certain limitations on Willis
Stein's ability to pursue transactions involving Aavid without our consent.
Following execution of the confidentiality agreement, and again on April 16,
1999, representatives of Willis Stein had a call with Mr. Eldred to discuss our
internal financial forecasts, focusing on expected revenue and gross margin
trends by business unit.

    On April 14, 1999, Messrs. Borelli, Eldred, Mitchell and Patel met with
representatives of H&Q to discuss H&Q's efforts to identify software company
acquisitions. H&Q reviewed with Aavid its efforts to date, noting that the
software companies approached were not interested in a transaction with Aavid,
and that other software companies were likely to be troubled by the prospect of
being linked to the manufacturing portion of Aavid's business. The discussion
turned to how Aavid could enhance long-term stockholder value. H&Q, on its own
initiative, suggested that management consider selling Aavid to provide the
greatest return to stockholders. H&Q was unaware at this time that we had
received a preliminary indication of interest to purchase Aavid.

    On April 19, 1999, Mr. Stein and other representatives of Willis Stein spoke
with Messrs. Borelli and Mitchell. They indicated that Willis Stein was
interested in pursuing a possible acquisition of Aavid at $22.00 per share,
which represented an approximately 43% premium to the $15.375 closing price of
our stock on that date. Willis Stein provided Aavid with its preliminary pricing
analysis showing how Willis Stein arrived at the $22.00 per share price. Willis
Stein's preliminary pricing analysis involved applying a leveraged buyout
analysis following a review of both thermal management and computational fluid
dynamics software industry data, as well as our historical financial performance
and our previously provided internal financial forecasts. Following the call
with Willis Stein, Messrs. Borelli, Macey, Mitchell and David Steadman, another
of our directors, had a conference call to discuss the Willis Stein indication
of interest.

    On April 20, 1999, the Aavid Board met to review the discussions with
Strategic Buyer 1, the Willis Stein indication of interest and H&Q's
unsuccessful efforts to date to find a software acquisition for Fluent. The
Aavid Board discussed whether to explore a possible sale of Aavid in light of
the discussions with Strategic Buyer 1, the indication of interest from Willis
Stein and H&Q's suggestion that management consider a sale of Aavid to provide
the greatest return to stockholders. The Aavid Board determined to engage H&Q to
assist Aavid in evaluating acquisition proposals, and formed a committee,
consisting of Messrs. Borelli, Macey (Chairman) and Steadman (the "Acquisitions
Committee"), to evaluate acquisition proposals and report back to the Aavid
Board. The Acquisitions Committee was also instructed to finalize the terms of
H&Q's engagement. A representative of Fulbright & Jaworski L.L.P. ("F&J"),
Aavid's outside counsel, reviewed with the Aavid Board their fiduciary
responsibilities.

    In late April, 1999, we engaged H&Q to act as our financial advisor with
respect to acquisition proposals. H&Q recommended that we not conduct a public
auction, but rather that H&Q, on behalf of Aavid, approach selected potential
strategic and financial buyers to determine their interest in

                                       33

acquiring Aavid. H&Q indicated that it believed that this selective process,
rather than a public auction, would limit disruption to our business from the
sale process, as well as limit damage to Aavid if no sale were consummated.

    In late April, 1999, Mr. Macey had discussions with a representative of
PaineWebber Incorporated regarding possible financial buyers which might be
interested in acquiring Aavid. PaineWebber suggested several possible financial
buyers and discussions were held with two of the identified buyers on a no-names
basis. One of these financial buyers indicated it had no interest, while the
other indicated an interest. PaineWebber then arranged a preliminary discussion
between this interested private equity investment firm ("Financial Buyer 1") and
Mr. Macey.

    On April 29, 1999, H&Q, at the suggestion of Mr. Macey, invited Financial
Buyer 1 to meet with us, and on that date we entered into a standard form of
confidentiality agreement with Financial Buyer 1, which included certain
limitations on its ability to pursue transactions involving Aavid without our
consent. On May 3, 1999, Messrs. Borelli, Eldred, Macey, Mitchell and Patel and
a representative of H&Q met with representatives of Financial Buyer 1 and its
financial advisor at our corporate offices in Concord, New Hampshire. The
participants discussed Aavid's operations and historical results, and Financial
Buyer 1 indicated it was interested in exploring a possible acquisition of
Aavid.

    On May 6, 1999, the Aavid Board held a meeting attended by representatives
of H&Q and F&J. Mr. Macey reviewed with the Aavid Board the meetings with Willis
Stein and Financial Buyer 1. The Aavid Board discussed whether to explore the
possibility of selling Aavid, which included a discussion in general terms of
the advantages and disadvantages of effecting a sale of Aavid. The advantages
discussed by the Aavid Board included creating greater value for our
stockholders, particularly in light of the Aavid Board's opinion that the stock
market was not valuing us properly. The disadvantages discussed by the Aavid
Board included the damage to Aavid that could be caused by a failed sale process
and that a sale for cash would not allow our stockholders to participate in any
future growth we might experience. H&Q reviewed with the Aavid Board various
short- and long-term market conditions and forces affecting Aavid and its stock
price. H&Q also reviewed with the Aavid Board a list of companies, other than
Strategic Buyer 1, and financial buyers, other than Willis Stein and Financial
Buyer 1, which H&Q believed might be interested in acquiring Aavid. The Aavid
Board, with advice from H&Q, chose two initial additional strategic buyers and
one additional financial buyer which they viewed as most likely to be interested
in, and financially able to, acquire Aavid, and directed H&Q to approach the
additional strategic and financial buyers regarding their possible interest in
Aavid. The Aavid Board also instructed H&Q to approach the two other most likely
strategic buyers which H&Q had identified to the Aavid Board if any of the three
initial strategic buyers was not interested in acquiring Aavid. None of the
strategic buyers identified by H&Q had operations in the thermal management
solutions industry; however, all the identified companies were suppliers of
connectors and other passive components with manufacturing processes and product
distribution systems similar to ours.

    On May 7, 1999, Messrs. Borelli, Eldred, Macey, Mitchell and Patel, and a
representative of H&Q met with senior management representatives of Strategic
Buyer 1 at our corporate offices in Concord, New Hampshire. The participants
discussed Aavid's operations and historical results, and Strategic Buyer 1
indicated it was interested in exploring a possible acquisition of Aavid. We and
Strategic Buyer 1 agreed to have more extensive discussions, after which
Strategic Buyer 1 indicated it would quickly decide whether to make an offer to
acquire us.

    During the week of May 10, 1999, representatives of H&Q contacted the two
additional strategic buyers and the one additional financial buyer chosen by the
Aavid Board.

    On May 10, 1999, Messrs. Borelli, Eldred and Patel met with representatives
of Financial Buyer 1 in Boston, Massachusetts to continue discussions regarding
a possible acquisition of Aavid by Financial Buyer 1.

                                       34

    On May 13 and 14, 1999, Messrs. Borelli, George Dannecker, President of
Aavid Thermal Products, Eldred, Mitchell, Patel and Garry Wheeler, Vice
President of Operations Center and Chief Information Officer of Aavid Thermal
Products, and representatives of H&Q met with representatives of Strategic Buyer
1 in Manchester, New Hampshire to continue discussions regarding a possible
acquisition of Aavid by Strategic Buyer 1. During these two days,
representatives of Strategic Buyer 1 conducted an intensive due diligence
examination of Aavid and its operations. Strategic Buyer 1 subsequently informed
us that it was not interested in continuing discussions regarding a possible
acquisition of us because such an acquisition did not fit within its growth and
technology strategy.

    On May 17, 1999, Messrs. Borelli, Eldred and Patel and representatives of
H&Q met with representatives of the one additional financial buyer contacted by
H&Q ("Financial Buyer 2"), at our corporate offices in Concord, New Hampshire.
The participants discussed Aavid's operations and historical results. Prior to
this meeting, we entered into a standard form of confidentiality agreement with
Financial Buyer 2, which included certain limitations on Financial Buyer 2's
ability to pursue transactions involving Aavid without our consent.

    On May 18, 1999, Messrs. Borelli, Eldred and Patel met with Messrs. Stein,
Dan Blumenthal and Kosty Gilis of Willis Stein at Willis Stein's offices in
Chicago, Illinois to continue discussions regarding a possible acquisition of
Aavid by Willis Stein.

    On May 19, 1999, Messrs. Borelli, Eldred and Patel met with representatives
of Financial Buyer 1 at our corporate offices in Concord, New Hampshire to
continue discussions regarding a possible acquisition of Aavid by Financial
Buyer 1.

    On May 20, 1999, representatives of H&Q requested that Willis Stein and
Financial Buyer 1 submit preliminary indications of interest relating to an
acquisition of Aavid to the Aavid Board by May 24, 1999, which date was
subsequently extended to May 25, 1999. In addition, H&Q contacted another
potential strategic buyer discussed with the Aavid Board at the May 6, 1999
meeting to determine whether it was interested in a possible acquisition of
Aavid.

    On May 21, 1999, Messrs. Borelli and Steadman and a representative of H&Q
held a telephone conference with a representative of another strategic buyer
identified by H&Q ("Strategic Buyer 2") to discuss Aavid's operations and
historical results.

    On May 24, 1999, the Acquisitions Committee, Mr. Mitchell and
representatives of H&Q and F&J had a conference call to discuss the status of
discussions regarding a possible acquisition of Aavid, as well as the increase
in Aavid's stock price, which had risen from $17.75 to $20.35 over the past ten
days.

    On May 25, 1999, both Willis Stein and Financial Buyer 1 submitted
preliminary written indications of interest in acquiring Aavid at $24.00 per
share, which represented an approximately 21% premium to the $19.75 closing
price of our stock on that date. Their respective letters indicated that their
indication of interest was subject to, among other things, satisfactory
completion of due diligence and satisfactory completion of debt financing for
the transaction. The Willis Stein letter also conditioned the indication of
interest on the grant to Willis Stein of a 30-day exclusive negotiating period,
and provided for a "topping fee" of $17 million, which is a fee we would have
had to pay to Willis Stein if we decided to enter into an acquisition
transaction with a party other than Willis Stein.

    On May 26, 1999, the Acquisitions Committee, Messrs. Mitchell and Patel and
representatives of H&Q had a conference call to discuss the status of
discussions. H&Q noted that Financial Buyer 2 had indicated that it was not
particularly interested in pursuing a transaction and that in any case based on
the current market price of the Aavid Common Stock it could not justify a bid
with a significant premium to the current price, and that the strategic buyers,
although initially interested, were not showing significant follow-up interest
in acquiring Aavid and were not likely to pursue an acquisition. The
participants discussed the initial proposals from Willis Stein and Financial
Buyer 1, and their expectations regarding the due diligence process, financing
contingencies, exclusivity and break-up fees. Following the meeting,
representatives of H&Q requested that Willis Stein and Financial Buyer 1

                                       35

submit their "best and final" proposal relating to an acquisition of Aavid to
the Aavid Board by May 28, 1999.

    On May 28, 1999, both Willis Stein and Financial Buyer 1 submitted revised
preliminary written indications of interest in acquiring Aavid at $24.00 per
share, which represented a 20% premium to the $20.00 closing price of our stock
on that date. Both indications of interest were on substantially the same terms
as set forth in their May 25, 1999, letters, except Willis Stein reduced its
requested "topping fee" to $5 million, and Financial Buyer 1 indicated it was
prepared to pursue the acquisition through a cash tender offer. The letter of
Financial Buyer 1 also now conditioned the indication of interest on the grant
to Financial Buyer 1 of a 30-day exclusive negotiating period.

    Following receipt of the indication of interest from Financial Buyer 1, the
Acquisitions Committee, Messrs. Eldred, Mitchell and Patel and representatives
of H&Q and F&J met to discuss the indications of interest from Willis Stein and
Financial Buyer 1. In the early afternoon of May 28, 1999, the Aavid Board met
with Messrs. Eldred and Mitchell along with representatives of H&Q and F&J.
Representatives of H&Q summarized H&Q's efforts to test the market for both
interest in and price of an acquisition of Aavid. H&Q noted that Strategic Buyer
1 and Financial Buyer 2 had declined to make offers after meeting with Aavid
management, and that the three other strategic buyers contacted had not
expressed interest in meeting with Aavid management. A representative of H&Q
then summarized the Willis Stein and Financial Buyer 1 proposals. The Aavid
Board then discussed the proposals. The Aavid Board instructed H&Q to obtain
from each of Willis Stein and Financial Buyer 1 additional information regarding
(1) the level of equity to be contributed by each, (2) whether a tender offer
with a back-end merger would be an acceptable structure and, if so, the minimum
number of shares required to be tendered, (3) the extent of remaining due
diligence, (4) the nature of financing commitments and (5) topping and break-up
fees.

    Following the Aavid Board meeting, Messrs. Eldred and Mitchell and
representatives of H&Q and F&J held discussions with Mr. Blumenthal of Willis
Stein and a representative of Bartlit Beck Herman Palenchar & Scott, counsel to
Willis Stein ("Bartlit Beck"), to clarify the Willis Stein proposal.
Representatives of H&Q also held discussions with representatives of Financial
Buyer 1 to clarify its proposal.

    On June 1, 1999, Financial Buyer 1 submitted a written response to the Aavid
Board's follow-up questions, and Willis Stein submitted a revised indication of
interest at $24.00 per share, addressing the Aavid Board's follow-up questions
and eliminating the previously proposed $5.0 million "topping fee". Following
receipt of these responses, the Aavid Board met to discuss the proposals.
Messrs. Eldred and Mitchell and representatives of H&Q and F&J participated in
the meeting. Mr. Macey summarized the two proposals, noting that (1) they were
both at the same price, (2) Financial Buyer 1 was willing to commit more equity
to the transaction, thereby increasing the likelihood of closing, (3) Financial
Buyer 1 appeared to be further along in both its due diligence and financing
arrangements and (4) both Financial Buyer 1 and Willis Stein were extremely
interested in acquiring Aavid. H&Q indicated that it believed the $24.00 price
was attractive. Following discussion of the two proposals, the Aavid Board
determined to pursue negotiations with Financial Buyer 1 because Financial Buyer
1 was willing to commit more equity to the transaction, thereby increasing the
likelihood of closing, and appeared to be further along in both its due
diligence and financing arrangements. The Aavid Board instructed management and
H&Q to continue negotiations with Financial Buyer 1. Following the Aavid Board
meeting, H&Q notified Mr. Blumenthal of Willis Stein that Aavid had elected to
pursue discussions with another party.

    On June 1, 1999, Mr. Carl Scheffer, the Bowthorpe executive responsible for
the Thermalloy Division invited Mr. Borelli to dinner to determine if Aavid
still had an interest in acquiring the Thermalloy Division. Mr. Scheffer and
Mr. Borelli discussed the Thermalloy Division's business, and Mr. Scheffer told
Mr. Borelli that Aavid would have to respond quickly and at a good price in
order to preclude an auction.

                                       36

    On June 2, 1999, before Aavid had formally accepted Financial Buyer 1's
indication of interest, Willis Stein submitted a revised indication of interest
at $24.50 per share, which represented a 17% premium to the $21.00 closing price
of our stock on that date, and further clarified certain points regarding the
level of its remaining due diligence and financing commitments.

    On June 3, 1999, the Acquisitions Committee met with Mr. Mitchell and
representatives of H&Q and F&J to discuss how to proceed in light of Willis
Stein's revised proposal. Following the Acquisitions Committee meeting, the
Aavid Board met to discuss the revised Willis Stein proposal. Messrs. Eldred and
Mitchell and representatives of H&Q and F&J participated in the Aavid Board
meeting. Mr. Macey reviewed with the Aavid Board the revised Willis Stein
proposal and the three possible alternatives to proceeding forward: (1) accept
the Willis Stein proposal; (2) go back to both Willis Stein and Financial Buyer
1 and again request a "final and best" proposal; or (3) give both Willis Stein
and Financial Buyer 1 several weeks to finish due diligence and arrange
financing and to come back with proposals that were not contingent on due
diligence or financing. H&Q's representatives advised the Aavid Board that it
did not believe Willis Stein and Financial Buyer 1 would proceed under the third
alternative, and recommended the second alternative. Following a discussion, the
Aavid Board instructed H&Q to inform both Financial Buyer 1 and Willis Stein to
submit a final and best proposal by June 7, 1999, and that the Aavid Board's
principal concerns were price and certainty of closure. The Aavid Board also
instructed H&Q to again contact the strategic buyers to see if they had any
interest in Aavid. The Aavid Board also determined, based on advice from H&Q and
F&J as to methods to induce Willis Stein and Financial Buyer 1 to submit their
"final and best" proposal, to offer the bidder whose proposal was accepted a
"topping fee" of $6 million, and instructed F&J to prepare a proposal for a
$6 million "topping fee".

    From June 3, 1999 to June 6, 1999, members of Aavid's management and
representatives of H&Q and F&J had conversations with Willis Stein, Financial
Buyer 1 and their respective representatives to answer questions and to
negotiate the proposed "topping fee" arrangement.

    On June 7, 1999, Willis Stein submitted a revised indication of interest at
$24.50 per share, which represented an approximately 4% premium to the $23.50
closing price of our stock on that date, and Financial Buyer 1 submitted a
revised indication of interest at $24.52 per share. Financial Buyer 1 also
offered an earnest money deposit of $100,000 which Aavid could retain under
limited circumstances. The Aavid Board met in the afternoon of June 7, 1999 to
discuss the indications of interest. Messrs. Eldred and Mitchell and
representatives of H&Q and F&J participated in the meeting. A representative of
H&Q summarized the proposals, noting that (1) Willis Stein's proposal remained
at $24.50 while Financial Buyer 1 had increased its proposal to $24.52;
(2) Willis Stein had increased the amount of equity it was willing to commit to
the transaction, and it now exceeded the amount Financial Buyer 1 was willing to
commit; (3) both proposals now contemplated tender offers, followed by back end
mergers, with a 50% minimum tender condition; (4) both indicated an ability to
obtain financing commitments, with Willis Stein having provided a
"highly-confident" letter from its bank; (5) Willis Stein indicated it would be
prepared to execute definitive agreements in 25 days and Financial Buyer 1
indicated an ability to do so in 30 days; and (6) Financial Buyer 1 proposed
that the topping fee be paid if Aavid entered into an agreement with respect to
another transaction, but Willis Stein only required the topping fee to be paid
if Aavid consummated another transaction. H&Q advised the Aavid Board that based
on its preliminary analysis, the $24.50 price was in the range of fairness.

    The Aavid Board then discussed both proposals, noting that the proposed
price was essentially identical, but that the additional $15 million of equity
which Willis Stein proposed to commit to the transaction would lead to a greater
certainty of closing. The Aavid Board noted that in the past, bank debt and high
yield debt markets have had periods of reduced liquidity where larger loans have
been difficult to obtain, and where banks and credit markets have required a
higher proportion of equity to debt in order to fund a transaction. The Aavid
Board also noted that there remained a great deal of uncertainty about both
proposals, including the need to complete due diligence and obtain financing,
and that the Aavid Board was not making any final determination to sell Aavid.

                                       37

    At the June 7, 1999, Aavid Board meeting Messrs. Borelli and Steadman
reported to the Aavid Board that Bowthorpe had approached Aavid to determine
whether Aavid would be interested in moving forward quickly to acquire
Thermalloy. Messrs. Borelli and Steadman reviewed with the Aavid Board Aavid's
prior discussions with Bowthorpe regarding Thermalloy. The Aavid Board also
discussed whether to pursue an acquisition of the Thermalloy Division in light
of the possible sale of Aavid, but determined that the sale discussions were
subject to completion of due diligence and the buyer's obtaining financing and
therefore at too preliminary a stage to justify not exploring a possible
acquisition of the Thermalloy Division. The Aavid Board discussed preliminary
price ranges for a possible Thermalloy transaction. A representative of H&Q
noted that the growth of Aavid by acquisition had been discussed in detail with
both Willis Stein and Financial Buyer 1, that the Thermalloy Division had been
mentioned as a possible acquisition target and, accordingly, that the price
offered by both Willis Stein and Financial Buyer 1 contemplated the possibility
of acquisitions by Aavid following its sale.

    Mr. Patel then reviewed with the Aavid Board the status of Aavid's search,
with the assistance of H&Q, for software company acquisitions. Mr. Patel noted
that software companies were not interested in transactions with Aavid because
of the thermal management products side of Aavid's business, and that as a
result Aavid could miss out on the ongoing consolidation of the analysis
software business. It was noted that because of the relatively small size of the
thermal management products business and Fluent, and the fact that separation of
the two businesses would be taxable to Aavid or its stockholders, it was not
feasible to split up the two businesses as long as Aavid remained a public
company.

    Following discussion of the foregoing matters, which included a discussion
of the effect the acquisition of the Thermalloy Division could have on a
proposed sale transaction, the Aavid Board determined to investigate a possible
sale of Aavid to Willis Stein. Following the Aavid Board meeting, Aavid granted
Willis Stein a 25-day exclusive negotiating period and a $6 million topping fee.
The Aavid Board also approved paying Messrs. Macey and Steadman $75,000 each for
their service on the Acquisitions Committee, regardless of whether a transaction
was consummated.

    On June 8, 1999, the Aavid Board held a meeting, which was also attended by
Messrs. Dannecker, Eldred and Mitchell and representatives of H&Q. H&Q reported
that Willis Stein had commenced working on the transaction. Mr. Steadman, who
had been requested by the Aavid Board to assist management in discussions with
Bowthorpe because of his extensive work with United Kingdom companies, updated
the Aavid Board regarding his discussions with Bowthorpe regarding Aavid's
possible acquisition of the Thermalloy Division. The Aavid Board approved paying
Mr. Steadman a fee of $50,000 for his work on the Thermalloy transaction,
regardless of the outcome.

    On June 14 and 15, 1999, Messrs. Borelli, Dannecker, Eldred, Mitchell and
Patel met in Concord, New Hampshire with Messrs. Blumenthal and Gilis of Willis
Stein, representatives of CIBC World Markets and Deutsche Bank Alex. Brown,
Willis Stein's financial advisors, representatives of Bain & Company,
consultants to Willis Stein, representatives of Ernst & Young, LLP, Willis
Stein's accounting advisors, and representatives of Bartlit Beck to begin their
in-depth due diligence review of Aavid and Thermalloy.

    From June 9, 1999 to June 18, 1999, Messrs. Borelli, Eldred, Macey,
Mitchell, Patel and Steadman negotiated the terms of, and a letter of intent
with Bowthorpe relating to, the acquisition of Thermalloy. On June 21, 1999,
Aavid entered into a non-binding letter of intent to acquire Bowthorpe's
Thermalloy Division, which was subject to our completion of satisfactory due
diligence, obtaining of financing and completion of definitive documentation.

    On June 22, 1999, the Aavid Board held a meeting, which Messrs. Eldred and
Mitchell and representatives of H&Q, F&J, Willis Stein and Bartlit Beck also
attended. The Aavid Board discussed the run-up in Aavid's stock price over the
past several days, noting that it had reached $25.00 on June 21, 1999, and had
closed at $24.50 on that date. Mr. Eldred advised the Aavid Board that he had
heard that rumors were circulating that Aavid was seeking a buyer, and H&Q noted
that the increase

                                       38

in Aavid's stock price was consistent with the increase that would occur if
rumors of a potential sale were circulating. The Aavid Board determined to issue
a press release announcing the Willis Stein and Thermalloy transactions in light
of the rumors, the difficulty in keeping both the Willis Stein and Thermalloy
transactions confidential pending completion of due diligence and definitive
documentation and the fact that the stock had traded up to the price Willis
Stein was prepared to pay per share of Aavid Common Stock. The Aavid Board also
believed that publicly announcing a possible sale of Aavid might induce another
party to seek to acquire Aavid at a price higher than the $24.50 per share which
Willis Stein had indicated it was willing to pay. However, although the Aavid
Board desired to name both Willis Stein as the potential buyer of Aavid and the
Thermalloy Division as the business to be acquired by Aavid, Bowthorpe was
unwilling to allow us to announce that the Thermalloy Division was the business
to be acquired and the letter of intent required Bowthorpe's consent to
disclosure unless required by law. Accordingly, in the morning of June 22, 1999,
we issued a press release announcing that (1) we were in discussions with
respect to a possible sale of Aavid to a private investment firm at a price of
$24.50 per share and (2) we had entered into a non-binding letter of intent for
a significant acquisition. The press release noted that both transactions were
at an early stage and were subject to completion of satisfactory due diligence,
obtaining of financing and completion of definitive documentation, and that
neither transaction was conditioned on completion of the other transaction.

    On June 25, 1999, Bartlit Beck circulated an initial draft of the Merger
Agreement to Aavid and F&J.

    On July 1, 1999, the Aavid Board met to discuss, among other things, the
Willis Stein and Thermalloy transactions. Messrs. Dannecker, Eldred and Mitchell
attended the meeting. In addition, representatives of F&J attended the portion
of the meeting relating to the Willis Stein and Thermalloy transactions, and
representatives of H&Q attended the portion of the meeting relating to the
Willis Stein transaction. Representatives of H&Q reviewed with the Aavid Board
their preliminary analysis of the fairness, from a financial point of view, of
the $24.50 price per share to Aavid stockholders without giving effect to the
acquisition of Thermalloy. Representatives of H&Q noted that at this time they
were not in a position to evaluate the fairness, from a financial point of view,
of the $24.50 price if Aavid were to acquire the Thermalloy Division because
they had not yet received detailed information about the Thermalloy Division.
The Aavid Board then proceeded to discuss the possible Thermalloy transaction,
focusing both on the benefits as well as the risks of the transaction, including
overburdening Aavid's senior management and the difficulty of retaining
customers, particularly on the computer and networking side of the business, and
integrating the operations of the Thermalloy Division into our operations. The
Aavid Board also approved the extension of the exclusive negotiating period
provided to Willis Stein to July 15, 1999.

    During the month of July, senior management of Aavid and Ernst & Young LLP,
who we and Willis Stein jointly retained as our accounting advisors for the
proposed acquisition of the Thermalloy Division, and our counsel conducted a due
diligence examination of the Thermalloy Division. During this period, senior
management of Aavid and Bowthorpe and their respective counsel negotiated the
terms of the acquisition agreement. Several members of Ernst & Young's due
diligence team which examined the Thermalloy Division on our behalf were also
part of the Ernst & Young due diligence team which examined us on behalf of
Willis Stein.

    On July 9, 1999, the Aavid Board met to discuss, among other things, the
proposed Thermalloy and Willis Stein transactions. Mr. Borelli noted that the
Thermalloy transaction was taking longer than expected, primarily because of the
legal and financial due diligence. Messrs. Eldred and Mitchell reported to the
Aavid Board that Willis Stein was continuing its financial and legal due
diligence examination of Aavid.

    On July 12, 1999, the Aavid Board met to discuss the proposed Thermalloy
transaction. Messrs. Dannecker, Eldred and Mitchell also attended the meeting.
Our senior management reviewed with the Aavid Board the operations and
historical results of the Thermalloy Division, as well as a pro

                                       39

forma forecast of combined operations. The Aavid Board also ratified the
engagement of Prudential Securities, Inc. to render an opinion as to the
fairness to Aavid, from a financial point of view, of the purchase price being
paid in the Thermalloy transaction. Mr. Borelli also reported to the Aavid Board
that Willis Stein was continuing its due diligence examination of Aavid and the
Thermalloy Division.

    On July 15, 1999, the Aavid Board met to discuss the proposed Thermalloy and
Willis Stein transactions. Messrs. Dannecker, Eldred and Mitchell, as well as
representatives of Prudential Securities and F&J, attended the meeting. The
Aavid Board reviewed in detail the Thermalloy transaction, including a
presentation by Prudential Securities as to its preliminary valuation analysis
with respect to the Thermalloy transaction. The Aavid Board authorized senior
management to continue negotiations with Bowthorpe and provided guidance with
respect to acceptable terms on major open items. Representatives of H&Q joined
the meeting and presented preliminary guidance as to the impact of the potential
acquisition of the Thermalloy Division with regard to Aavid's valuation and to
negotiations with Willis Stein. The Aavid Board also approved the extension of
the exclusive negotiating period provided to Willis Stein to August 6, 1999.

    On July 20, 1999, the Aavid Board met to discuss, among other things, the
proposed Thermalloy and Willis Stein transactions. Messrs. Eldred and Mitchell
and a representative of F&J also attended the meeting. Our senior management
updated the Aavid Board as to the status of the negotiations with Bowthorpe and
Willis Stein.

    On July 26, 1999, Messrs. Borelli, Eldred and Patel and a representative of
H&Q met with Messrs. Stein, Blumenthal and Gilis of Willis Stein to continue
negotiations regarding Willis Stein's proposed acquisition of Aavid and to
review the results of our due diligence examination of the Thermalloy Division.
On July 26, 1999, representatives of F&J and Bartlit Beck discussed open issues
on the initial draft merger agreement prepared by Bartlit Beck.

    On July 28, 1999, the Aavid Board met to discuss the Willis Stein and
Thermalloy transactions. Messrs. Dannecker, Eldred and Mitchell, as well as
representatives of H&Q and F&J, also attended the meeting. Messrs. Patel and
Mitchell summarized for the Aavid Board the status of negotiations with
Bowthorpe regarding the acquisition of Thermalloy, focusing particularly on the
open issues identified at the July 15, 1999 meeting of the Aavid Board. The
Aavid Board authorized senior management to continue negotiations with Bowthorpe
and provided guidance with respect to acceptable terms on the remaining open
items.

    Representatives of H&Q then reviewed with the Aavid Board possible
alternatives, which included (1) pursuing a transaction with Willis Stein but
not the acquisition of the Thermalloy Division, (2) pursuing a transaction to
acquire the Thermalloy Division but not the Willis Stein transaction,
(3) pursuing the acquisition of the Thermalloy Division and a higher price in
the Willis Stein transaction, (4) pursuing the Thermalloy transaction and
putting a sale transaction on "hold" until the acquisition of the Thermalloy
Division had been completed and the integration process implemented or
(5) trying to "spin-off" or otherwise obtain value for Fluent. In discussing the
alternatives, it was noted that since our June 22, 1999 public announcement that
we were contemplating an acquisition and the sale of Aavid at $24.50 per share,
no party had contacted us or our financial advisor which was prepared to make a
superior proposal. Following the discussion of alternatives, H&Q reviewed with
the Aavid Board their preliminary analysis of the fairness, from a financial
point of view, of the $24.50 price per share to Aavid stockholders both giving
effect to Aavid's acquisition of Thermalloy and on a stand-alone basis. H&Q also
reviewed with the Board an analysis of the incremental value to Aavid of the
acquisition of the Thermalloy Division. A representative of F&J then reviewed
with the Aavid Board the principal terms of the proposed agreement with Willis
Stein and the open issues. The Aavid Board also discussed whether it should
require a higher price from Willis Stein to accept a transaction with Willis
Stein in light of the Thermalloy transaction.

                                       40

    On August 2, 1999, the Acquisitions Committee and representatives of H&Q and
F&J met to discuss the open issues in the Willis Stein transaction and the
process of how to approach Willis Stein to obtain an increase in the price to be
paid by Willis Stein for Aavid.

    On August 5, 1999, Messrs. Borelli and Macey met at Willis Stein's offices
in Chicago, Illinois with Messrs. Stein, Blumenthal and Gilis of Willis Stein
and their respective legal and financial advisors to discuss the open issues in
the Willis Stein transaction, including the price to be paid by Willis Stein for
Aavid. Representatives of H&Q provided an analysis of why the acquisition of the
Thermalloy Division justified a higher price from Willis Stein, while Willis
Stein and its advisors provided an analysis of why the acquisition of the
Thermalloy Division did not justify a price increase. Willis Stein initially
declined to agree to an increase in the price per share they were prepared to
offer, but following lengthy discussions, Willis Stein proposed increasing the
purchase price per share of Aavid Common Stock to $25.25, but changing the
structure of the transaction from a tender offer with a back end merger to a
merger, and conditioning the transaction on our completion of the acquisition of
the Thermalloy Division. Willis Stein also offered to retain its $24.50 offer if
Aavid did not for any reason complete the Thermalloy acquisition.

    On August 5, 1999, the Aavid Board met, with Messrs. Eldred and Mitchell and
representatives of H&Q, Prudential Securities and F&J also participating in the
meeting. Our senior management reviewed with the Aavid Board the status of the
negotiations with Bowthorpe regarding the acquisition of Thermalloy, noting that
the previously open issues had been resolved and that the final stock purchase
agreement and disclosure schedules were being prepared. Prudential Securities
then reviewed with the Aavid Board its financial analysis of the transaction,
and orally delivered its opinion, subsequently confirmed in writing, that the
then proposed consideration to be paid by Aavid in the Thermalloy transaction
was fair to Aavid from a financial point of view. Mr. Mitchell and a
representative of F&J reviewed with the Aavid Board the principal terms of the
stock purchase agreement. The Aavid Board then proceeded to discuss the
transaction. Following the discussion, the Aavid Board approved the acquisition
of Thermalloy on the terms set forth to the Aavid Board. Messrs. Borelli and
Macey, together with representatives of H&Q, then reviewed with the Aavid Board
the negotiations with Willis Stein and Willis Stein's proposal to acquire Aavid.
The Aavid Board discussed the Willis Stein proposal, and requested that H&Q
prepare a further analysis of the incremental value to Aavid of the acquisition
of the Thermalloy Division. The Aavid Board also approved the extension of the
exclusive negotiating period provided to Willis Stein to August 12, 1999.

    On August 9, 1999, the Aavid Board met, with Messrs. Eldred and Mitchell and
representatives of H&Q and F&J also participating. The Aavid Board discussed the
Willis Stein proposal and the analysis prepared by H&Q relating to the
incremental value to Aavid of the acquisition of the Thermalloy Division.
Representatives of H&Q then reviewed with the Aavid Board their preliminary
analysis of the fairness, from a financial point of view, of both (1) the $25.25
price per share to Aavid stockholders giving effect to Aavid's acquisition of
the Thermalloy Division and (2) the $24.50 price per share to Aavid stockholders
on a stand-alone basis if the Thermalloy transaction did not occur. The Aavid
Board then discussed the Willis Stein proposal. The Aavid Board directed H&Q to
go back to Willis Stein and seek to increase the price to $25.50 per share, with
a Willis Stein commitment to proceed with the acquisition of Aavid at $24.50 per
share if the acquisition of the Thermalloy Division did not occur. The Aavid
Board meeting was adjourned while H&Q negotiated with Willis Stein.

    When the meeting of the Aavid Board reconvened, H&Q informed the Aavid Board
that Willis Stein was prepared to pay $25.50 per share, conditioned on our
completion of the acquisition of the Thermalloy Division, and to commit to
acquire Aavid at $24.50 per share even if the Thermalloy transaction was not
completed. The Aavid Board authorized senior management to continue negotiations
with Willis Stein and provided guidance with respect to acceptable terms on the
remaining open items.

                                       41

    On August 11, 12 and 13, 1999, Mr. Borelli and representatives of F&J met
with Messrs. Blumenthal and Gilis and representatives of Bartlit Beck to
finalize the merger agreement. The Acquisitions Committee, Mr. Mitchell and a
representative of F&J had several conversations during this period regarding the
voting agreement that Willis Stein requested several directors and officers
enter into, as well as the amount of the break-up fee, which Willis Stein had
originally requested be approximately $13 million, and the circumstances under
which it would be payable. On August 12, 1999, Aavid extended the exclusive
negotiating period provided to Willis Stein to August 20, 1999.

    On August 16, 1999, the Aavid Board met, with Messrs. Eldred and Mitchell
and a representative of F&J also participating. Mr. Borelli advised the Aavid
Board that there had been a deterioration in the performance of the Thermalloy
Division from the forecasts originally provided to Aavid. The Aavid Board
discussed the deterioration and an acceptable reduction in the purchase price
for the Thermalloy Division in light of this deterioration. The Aavid Board
authorized senior management to seek a reduction in purchase price for the
Thermalloy Division and provided guidance with respect to acceptable terms.
Mr. Borelli then reviewed with the Aavid Board the final outcome of the
negotiations with Willis Stein. The Aavid Board discussed the final terms of the
agreement, including the amount of the break-up fee and the circumstances under
which it would be paid.

    From August 16, 1999 through August 20, 1999, Mr. Borelli negotiated the
reduction in the purchase price of the Thermalloy Division with representatives
of Bowthorpe.

    On August 18, 1999, the Aavid Board met, with Messrs. Eldred and Mitchell
and a representative of F&J also participating. Mr. Borelli summarized for the
Aavid Board the status of negotiations with Bowthorpe regarding the reduction in
the purchase price for the Thermalloy Division. The Aavid Board authorized
senior management to continue negotiations with respect to a reduction in
purchase price for the Thermalloy Division and provided guidance with respect to
acceptable terms.

    On August 20, 1999, Aavid extended the exclusive negotiating period provided
to Willis Stein to August 23, 1999.

    On August 22, 1999, the Aavid Board met, with Messrs. Eldred and Mitchell
and representatives of H&Q and F&J also participating. Mr. Borelli reviewed with
the Board the final terms of the acquisition of the Thermalloy Division.
Following a discussion, the Aavid Board, with Mr. Patel absent, approved the
acquisition of the Thermalloy Division.

    Mr. Borelli then reviewed with the Aavid Board the terms of the Willis Stein
transaction. A representative of F&J then summarized for the Aavid Board the
terms of the Merger Agreement. Representatives of H&Q then reviewed with the
Aavid Board H&Q's financial analysis of the Willis Stein transaction, and orally
delivered its opinion, subsequently confirmed in writing, that the consideration
to be received by the holders of the Aavid Common Stock was fair to such holders
from a financial point of view. Following a discussion, the Aavid Board, with
Mr. Patel absent, approved the Merger and the Merger Agreement.

    On August 23, 1999, our senior management finalized the Stock Purchase
Agreement with Bowthorpe. We signed the Stock Purchase Agreement with Bowthorpe
and the Merger Agreement with MergerCo and Holdings, entities newly formed by
Willis Stein for purposes of the Merger, on the evening of August 23, 1999, and
the transactions were publicly announced that evening.

OUR REASONS FOR THE MERGER

    In concluding that the Merger is in the best interests of Aavid and its
stockholders, and in approving the Merger Agreement and the transactions
contemplated by the Merger Agreement (including the Merger), the Aavid Board
considered and reviewed with senior management, as well as its financial and
legal advisors, a number of factors, including the following:

    - the Aavid Board's familiarity with, and information provided by our
      management as to, the business, financial condition, results of
      operations, current business strategy and future prospects

                                       42

      of Aavid (including the Thermalloy Division, which Aavid had agreed to
      acquire), as well as the risks involved in achieving those prospects and
      objectives in current industry and market conditions, the nature of the
      markets in which we operate, our position in such markets, and the
      historical and current market prices for our shares.

    - the strategic options available to Aavid, including the option of
      continuing to operate Aavid as an independent, publicly-traded company,
      and the Aavid Board's assessment that none of these options were
      reasonably likely to present superior opportunities, or were reasonably
      likely to create greater value for Aavid stockholders, than the prospects
      presented by the Merger. In particular, Aavid, whose market capitalization
      had never exceeded $302 million, was viewed by the investment community as
      a "micro-cap" company, which is a company with a market capitalization of
      less than $500 million. The Aavid Board believed that being viewed as a
      "micro-cap" company has had an adverse effect on the trading price of the
      Aavid Common Stock, particularly since "micro cap" companies were out of
      favor with the investment community. Further, the Aavid Board believes the
      investment community did not properly value the computational fluid
      dynamics ("CFD") software segment of our business, and Aavid would be
      unable to "spin-off" Fluent on a tax-free basis until October 2000, and,
      in any case, the Aavid Board believed that Fluent, without additional
      acquisitions, would be too small in the current market environment to
      succeed as a stand-alone public company. The Aavid Board also believed
      that the acquisition of the Thermalloy Division entailed significant risks
      with respect to integration of the operations of both companies and the
      deteriorating performance of the Thermalloy Division. The Aavid Board also
      believed that even after the acquisition of the Thermalloy Division, it
      would still be a "micro-cap" company out of favor with the investment
      community.

      In addition, the Aavid Board believed that continuing to operate Aavid as
      a public company entailed meaningful risks in the execution of Aavid's
      business strategy, particularly in light of the acquisition of the
      Thermalloy Division. In particular, the Aavid Board believed that
      executing this strategy would include making large acquisitions (including
      the acquisition of the Thermalloy Division) that would likely result in a
      substantial increase in the debt to equity ratio of Aavid unless such
      acquisitions could be made with equity, and that given the relatively low
      price of Aavid Common Stock during the latter half of 1998 and the first
      half of 1999, any acquisitions made using equity would likely be dilutive
      to existing stockholders. The Aavid Board noted that software companies
      which Aavid desired to acquire to expand and complement Fluent's CFD
      business were unwilling to accept Aavid Common Stock as consideration
      because of the relatively low price of the stock and their lack of
      familiarity and comfort with the thermal management products segment of
      the business. The Aavid Board also believed that growth through large
      acquisitions involves substantial investment risks to Aavid's
      stockholders, particularly with respect to integrating such acquisitions
      and managing rapid growth. Additionally, acquisitions would put a
      significant strain on our management resources, and Mr. Borelli, our
      Chairman and Chief Executive Officer, had indicated that he would not
      continue in those positions on a full-time basis following expiration of
      his employment agreement on December 31, 1999.

      After considering the foregoing, the Aavid Board concluded that, while
      Aavid's business strategy could ultimately prove successful, the sale of
      Aavid would provide all Aavid stockholders with liquidity for their
      investment at a price that the Aavid Board considered fair and which was
      significantly in excess of the historical trading price since
      mid-July 1998. The Aavid Board also considered the fact that consummation
      of the Merger would preclude Aavid's stockholders from having the
      opportunity to participate in the future growth prospects of Aavid,
      particularly in light of its proposed acquisition of the Thermalloy
      Division. Although the Aavid Board took its internal financial forecasts
      into account in determining whether to approve the Merger, the Aavid Board
      did not consider its internal financial forecasts material in evaluating
      the option of

                                       43

      continuing to operate Aavid as an independent company or in evaluating the
      fairness of the merger consideration.

    - the process engaged in by our management and financial advisor, which
      included discussions with a number of potential acquirors, as a result of
      which the Aavid Board had what it believed to be an accurate sense of the
      values that could be achieved in a third party transaction. The Aavid
      Board believed that the Merger was the best offer reasonably available for
      Aavid stockholders, and that there were no other prospective buyers that
      both had the financial ability to complete a transaction and would be
      willing to pay an aggregate consideration greater than that to be paid by
      Willis Stein in the Merger. In seeking to maximize value to the Aavid
      stockholders, Aavid and its financial advisors contacted both likely
      strategic and financial buyers to determine their interest in acquiring
      Aavid, and thereafter received only two indications of interest. The Aavid
      Board was advised by its financial advisor that the strategic buyers were
      not interested in Aavid primarily because they were not presently
      interested in the thermal management solutions industry. In addition, the
      Aavid Board considered the fact that during the two month period between
      the public announcement on June 22, 1999 that it was contemplating an
      acquisition and the sale of Aavid at $24.50 per share and the signing of
      the Merger Agreement, no party contacted Aavid or its financial advisor
      which was prepared to make a superior proposal. Financial Buyer 2's $24.52
      offer was received on June 7, 1999, prior to the Aavid Board's decision to
      pursue a transaction with Willis Stein. The Aavid Board also considered
      the fact that with the change in structure of the Willis Stein transaction
      from a tender offer to a merger and the need to close the acquisition of
      the Thermalloy Division before mailing this Proxy Statement to
      stockholders, there would be at least an additional three month period
      after the public announcement of the signing of the Merger Agreement and
      the signing of the stock purchase agreement to acquire the Thermalloy
      Division for other parties which might be interested in acquiring Aavid at
      a higher price to come forward before we closed the Merger.

    - the fact that the cash merger consideration on a per share basis
      represented a premium over the price initially agreed to and over
      prevailing market prices of Aavid Common Stock prior to the time it began
      exploring the sale of Aavid. In considering the amount of the premium to
      the current trading price and recent historical trading prices of the
      Aavid Common Stock represented by the cash merger consideration, the Aavid
      Board noted that the June 22, 1999 announcement of a possible sale of
      Aavid at $24.50 per share had likely affected trading in Aavid Common
      Stock, and that the price of the Aavid Common Stock since that
      announcement was probably higher than it would have been absent such
      announcement.

    - the strategic and financial review conducted by Hambrecht & Quist, and the
      oral opinion of Hambrecht & Quist (subsequently confirmed in writing dated
      as of August 22, 1999), that, as of the date of its opinion and based on
      the assumptions and subject to the limitations and qualifications set
      forth therein, the $25.50 per share merger consideration was fair, from a
      financial point of view, to the holders of Aavid Common Stock.

    - the analyses performed by Hambrecht & Quist in connection with rendering
      its fairness opinion, including Hambrecht & Quist's comparable public
      company, comparable merger and acquisition transaction, discounted
      potential future share price, discounted cash flow and leveraged buyout
      analyses, on both an Aavid stand-alone basis and on a pro forma basis
      giving effect to Aavid's acquisition of the Thermalloy Division.

    - the terms of the Merger and the Merger Agreement as negotiated, including
      (1) the $25.50 per share cash merger consideration, (2) the fact that
      Willis Stein was willing to commit to consummate the Merger at a per share
      cash merger consideration of $24.50 per share even if we were unable to
      complete our acquisition of the Thermalloy Division, (3) that the Merger
      Agreement permits us to furnish non-public information to, and to
      participate in negotiations

                                       44

      with, any third party with respect to a bona fide offer to acquire Aavid
      if the Aavid Board concludes in good faith on the advice of outside
      counsel that such action by the Aavid Board is necessary in order for the
      Aavid Board to comply with its fiduciary duties to Aavid's stockholders,
      (4) the fact that the Merger Agreement provides that, subject to the
      satisfaction of certain conditions, the Aavid Board would be able to
      withdraw or modify its recommendation to the Aavid stockholders regarding
      the Merger and enter into an agreement with respect to a more favorable
      transaction with a third party, if such a transaction becomes available
      prior to the consummation of the Merger and (5) the possibility that the
      Merger Agreement might discourage other parties that might have an
      interest in a business combination with Aavid.

    - the fact that the Merger Agreement requires it to be submitted to the
      Aavid stockholders for approval, which allows for an informed vote by
      Aavid's stockholders on the merits of the transaction without requiring a
      tender of shares or other potentially coercive transaction structure.

    - the financial ability and willingness of Willis Stein to consummate the
      Merger, and the fact that financing is not a condition to Holdings'
      obligation to complete the Merger. The Aavid Board considered the fact
      that Willis Stein was going to finance the transaction with a combination
      of equity capital and debt financing, and that Willis Stein had committed
      to invest up to $146 million of equity in the transaction, and had
      obtained debt financing commitments sufficient to provide the necessary
      financing with which to consummate the Merger, and had delivered to the
      Aavid Board financing commitment letters for the debt and equity
      financing.

    - the likelihood of the Merger being approved by requisite regulatory
      authorities.

    - the interests that are different from, or in addition to, the interests of
      Aavid stockholders generally, as described under "Interests of Our
      Officers and Directors in the Merger" on page 54. In this regard, the
      Aavid Board noted that there had been no discussions between Willis Stein
      and our management with respect to their equity participation after the
      closing of the Merger and, therefore, management's interest as
      stockholders was aligned with our other stockholders. The Aavid Board also
      noted that the Aavid Common Stock and options owned by its senior
      management constituted a significant amount of senior management's net
      worth.

    This discussion of the information and factors considered by the Aavid Board
is not meant to be exhaustive, but includes the material information and factors
considered by the Aavid Board. In reaching its determination to approve the
Merger Agreement and the transactions contemplated thereby, the Aavid Board did
not assign any relative or specific weight to the information and factors
discussed above, and individual directors may have assessed various factors
differently. The Aavid Board is unanimous in its recommendation that Aavid
stockholders vote to approve the Merger Agreement.

OPINION OF AAVID'S FINANCIAL ADVISOR

    We engaged Hambrecht & Quist to act as our exclusive financial advisor in
connection with the proposed transaction and to render an opinion as to the
fairness, from a financial point of view, to the holders of shares of Aavid
Common Stock of the consideration to be received by such stockholders in the
Merger. We selected Hambrecht & Quist based on Hambrecht & Quist's
qualifications, experience and reputation in mergers and acquisitions.
Hambrecht & Quist rendered its oral opinion (as confirmed in writing) on
August 22, 1999 to the Aavid Board that, as of such date, the consideration to
be received in the Merger by holders of Aavid Common Stock was fair, from a
financial point of view, to such holders. The amount of the consideration was
determined through negotiations between Willis Stein and Aavid. Hambrecht &
Quist did not recommend to us that any specific consideration was appropriate
for the transaction.

                                       45

THE PROPOSED TRANSACTION OR ANY OTHER TRANSACTIONS OR BUSINESS STRATEGIES
DISCUSSED BY THE AAVID BOARD AS ALTERNATIVES TO THE PROPOSED TRANSACTION, OR THE
UNDERLYING BUSINESS DECISION OF THE AAVID BOARD TO PROCEED WITH THE TRANSACTION.
IN FURNISHING ITS OPINION, HAMBRECHT & QUIST DID NOT ADMIT THAT IT IS AN EXPERT
WITHIN THE MEANING OF THE TERM "EXPERT" AS USED IN THE SECURITIES ACT, NOR DID
IT ADMIT THAT ITS OPINION CONSTITUTES A REPORT OR VALUATION WITHIN THE MEANING
OF THE SECURITIES ACT. THE SUMMARY OF HAMBRECHT & QUIST'S OPINION SET FORTH
BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF ITS OPINION.
YOU ARE URGED TO READ THE OPINION CAREFULLY IN ITS ENTIRETY.

    In arriving at its opinion, Hambrecht & Quist, among other things:

    - Reviewed with the Aavid Board and members of management Aavid's financial
      plans, its strategic plans and business alternatives;

    - Discussed the business, financial condition and prospects of Aavid with
      certain members of senior management;

    - Assisted Aavid in the evaluation and selection of potential acquirers and
      represented Aavid in contacting, qualifying and negotiating with the
      potential acquirer;

    - Met with the Aavid Board and members of management to discuss Aavid's
      position and recommendations to stockholders concerning the proposal to
      acquire Aavid, as well as strategic alternatives and their financial
      implications;

    - Assisted Aavid in the preparation of confidential descriptive materials
      for review by potential acquirers in connection with their evaluation of a
      sale transaction;

    - Reviewed the recent reported prices and trading activity for the Aavid
      Common Stock and compared such information and certain financial
      information for Aavid with similar information for certain other companies
      engaged in businesses we consider comparable;

    - Reviewed the financial terms, to the extent publicly available, of certain
      comparable merger and acquisition transactions;

    - Reviewed published Wall Street research estimates for projections of
      Aavid's future financial performance;

    - Reviewed the final draft of the Merger Agreement to be entered into; and

    - Conducted such other studies and inquiries, and reviewed such other data,
      as Hambrecht & Quist deemed relevant.

    Hambrecht & Quist did not assume responsibility for the independent
verification of, and did not independently verify, any of the information
concerning Aavid in connection with its review of the proposed transaction and,
in preparing its opinion, Hambrecht & Quist assumed and relied upon the
accuracy, completeness and fairness of all such information. In connection with
its opinion, Hambrecht & Quist did not prepare or obtain any independent
valuation or appraisal of any of the assets or liabilities of Aavid, nor did it
conduct a physical inspection of the properties and facilities of Aavid. With
respect to the financial projections used in its analysis, Hambrecht & Quist
assumed that

                                       46

they reflected the best currently available estimates and judgments of the
expected future financial performance of Aavid and that they provided a
reasonable basis upon which Hambrecht & Quist could form its opinion.
Hambrecht & Quist assumed that Aavid was not a party to any pending
transactions, including external financings, recapitalizations or merger
discussions, other than the proposed transaction, the potential acquisition of
the Thermalloy Division (the "Thermalloy Acquisition"), and those activities
undertaken in the ordinary course of conducting the respective businesses of
Aavid and the Thermalloy Division. Hambrecht & Quist assumed that both the
proposed transaction and the Thermalloy Acquisition will be accounted for as
purchase transactions. Hambrecht & Quist further assumed that, in all respects
material to its analysis, the representations and warranties of Holdings,
MergerCo and Aavid contained in the Merger Agreement are true and correct,
Holdings, MergerCo and Aavid will each perform all of the covenants and
agreements to be performed by it under the Merger Agreement, all conditions to
the obligations of each of Holdings, MergerCo and Aavid to effect the proposed
transaction will be satisfied and the proposed transaction would be consummated
substantially on the terms specified in the Merger Agreement, in each case
without any waiver or modification of any material terms or conditions by any
party thereto.

    Hambrecht & Quist's opinion is necessarily based upon market, economic,
financial and other conditions as they existed and can be evaluated on, and
information made available to Hambrecht & Quist as of, the date of the opinion
and any subsequent change in such conditions would require a reevaluation of
such opinion. Hambrecht & Quist assumes no obligation to update, revise or
affirm its opinion. Hambrecht & Quist expresses no opinion on the fairness of
other potential transactions between Aavid, the MergerCo, the stockholders or
any other parties, including, but not limited to, the potential Thermalloy
Acquisition.

    The preparation of a fairness opinion is a complex process and involves
various subjective judgments and determinations as to the most appropriate and
relevant assumptions and financial analyses and the application of these methods
to the particular circumstances involved. Such an opinion is therefore not
necessarily susceptible to partial analysis or summary description. Accordingly,
Hambrecht & Quist believes that its analyses and the summary set forth below
must be considered as a whole and that selecting portions of its analyses,
without considering all analyses, or of the following summary, without
considering all factors and analyses, could create an incomplete and misleading
view of the processes underlying the analyses performed by Hambrecht & Quist in
connection with its opinion. In arriving at its opinion, Hambrecht & Quist did
not attribute any particular weight to any analyses or factors considered by it,
but rather made qualitative judgments as to the significance and relevance of
each analysis and factor. Hambrecht & Quist did not form an opinion as to
whether any individual analysis or factor (positive or negative), considered in
isolation, supported or failed to support the Hambrecht & Quist opinion. In
performing its analyses, Hambrecht & Quist made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond Aavid's control. The analyses performed
by Hambrecht & Quist do not necessarily confirm actual values and are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than suggested by such analyses, and Hambrecht & Quist assumes
no responsibility if actual values or future results are materially different
from its assumptions or the results of its analyses. Such analyses were prepared
solely as part of the Hambrecht & Quist analysis of the fairness to Aavid
stockholders, from a financial point of view, of the consideration in the
proposed transaction. Additionally, analyses relating to the values of
businesses do not purport to be appraisals or to reflect the prices at which
businesses actually may be acquired.

    The following is a brief summary of the material financial analyses
performed by Hambrecht & Quist in connection with providing its opinion to the
Aavid Board on August 22, 1999. Some of the summaries of the financial analyses
include information presented in tabular format. To fully understand the
financial analyses, you should read the tables together with the text of each
summary. Considering the data set forth in the tables without considering the
narrative description of the

                                       47

financial analyses, including the methodologies and assumptions underlying the
analyses, could create a misleading or incomplete view of the financial
analyses. In all of the financial analyses, Hambrecht & Quist calculated an
implied valuation for both Aavid on a stand-alone basis without the Thermalloy
Acquisition ("Stand-Alone Analysis"), and also for Aavid pro forma for the
acquisition of the Thermalloy Division ("Pro Forma for Thermalloy Analysis").
Because the Thermalloy Acquisition has been consummated and the merger
consideration will therefore be $25.50 per share, only the Pro Forma for
Thermalloy Analysis is presented below.

    We have obtained Hambrecht & Quist's consent to the following summary of the
financial analyses performed by Hambrecht & Quist and the reference to
Hambrecht & Quist in this Proxy Statement. Hambrecht & Quist has advised us that
in giving its consent, it is not admitting that its consent is required under
the Exchange Act.

    ANALYSIS OF SELECTED PUBLIC COMPANIES.  Hambrecht & Quist believes that
there are no public companies directly comparable to Aavid in terms of
underlying technology, market focus and market capitalization. Based on this,
Hambrecht & Quist chose one group of representative large capitalization stocks
with technology and/or market focus roughly similar to Aavid's software business
(the "software division") and one group of representative large capitalization
stocks with technology and/or market focus roughly similar to Aavid's thermal
management products business (the "hardware division"). The substantially larger
market capitalizations relative to Aavid of the large capitalization stocks
means that valuation statistics such as P/E multiples or Price/Revenues ratios
derived from analysis of these companies cannot be directly applied to Aavid's
actual or projected financial results. Hambrecht & Quist also chose a broad list
of micro-capitalization stocks which share characteristics of Aavid's hardware
or software divisions' technology and/or market focus and which have market
capitalizations approximately similar to Aavid. Using published Wall Street
estimates and Hambrecht & Quist research regarding these stocks, Hambrecht &
Quist compared, among other things, certain trading, operating and valuation
statistics for Aavid to corresponding measures for these selected companies:

    - "Large-Cap" Software Companies:

       - Cadence

       - Mentor Graphics

       - Structural Dynamics Research

       - Tecnomatix

    Hambrecht & Quist derived trading multiples of equity share prices to
projected revenue for calendar years 1999 and 2000 and projected earnings per
share for calendar years 1999 and 2000 for these public companies. This analysis
produced "Average Excluding High and Low" multiples which are summarized in the
table below:



                                                    "LARGE-CAP"     "LARGE-CAP"       "MICRO-CAP"
                                                     SOFTWARE        HARDWARE        COMPONENT AND
                                                     COMPANIES       COMPANIES     SOFTWARE COMPANIES
                                                   -------------   -------------   ------------------
                                                                          
Calendar Year 1999 (estimated) Price/Revenues....       1.8x            2.0x              1.2x
Calendar Year 2000 (estimated) Price/Revenues....       1.7x            1.9x               .8x
Calendar Year 1999 (estimated) Price/Earnings....      19.0x           27.5x             14.4x
Calendar Year 2000 (estimated) Price/Earnings....      12.5x           21.1x             11.3x


    To apply the "Large-Cap" multiples listed above, Hambrecht & Quist first
calculated blended multiples based on the proportion of Aavid's 1999 and 2000
revenue contribution attributable to its hardware and software divisions pro
forma for the Thermalloy Acquisition multiplied by the respective Price/Revenues
multiples for the "Large-Cap" Hardware and "Large-Cap" Software companies. In
addition, based on analyses of the valuation of selected large capitalization
stocks, stock indices and stock index components relative to small
capitalization stocks, stock indices and stock index components, Hambrecht &
Quist applied a discount factor range of 25% to 50% to the blended "Large-Cap"
multiples as representing an appropriate adjustment for the significantly
smaller market capitalization of Aavid relative to these "Large-Cap" companies.
Applying these calculations to the projected 1999 and 2000 pro forma revenues
indicated a range of an implied equity value per share from $18.21 to $44.22.
Hambrecht & Quist also applied the same methodology to Aavid's 1999 and 2000 pro
forma net income projections and derived a range of an implied equity value per
share from $15.56 to $23.88. Hambrecht & Quist also calculated an implied equity
value per share by applying the "Micro-Cap" multiples listed above. Applying the
1999 and 2000 "Micro-Cap" revenue multiples indicated a range of an implied
equity value per share from $19.59 to $20.91, while applying the 1999 and 2000
"Micro-Cap" net income multiples indicated a range of $18.37 to $19.79. These
values were compared to an equity value per share of Aavid Common Stock in the
proposed transaction of $25.50 as of August 18, 1999, subject to the successful
completion of the Thermalloy Acquisition, and Aavid's closing price per share of
$20.81 on August 18, 1999.

    Hambrecht & Quist noted that no company used in the above analyses is
identical to Aavid. Accordingly, an analysis of the results of the foregoing is
not simply mathematical; rather it requires complex qualitative considerations
and judgments concerning differences in financial and operating characteristics
of the companies and other factors that could affect the public trading values
of the companies or company to which they are compared.

    ANALYSIS OF SELECTED TRANSACTIONS.  Hambrecht & Quist compared the proposed
transaction with selected representative merger and acquisition transactions.
Hambrecht and Quist derived the multiples of common equity transaction value
(adjusted for debt and cash) to revenues, EBITDA, EBIT and net income on a
trailing twelve month basis for 12 transactions since 1996 for which relevant
information was available and the premiums of the per share transaction value to
the one trading day and twenty trading day per share market values for 12
transactions since 1996 for which relevant information was available.
Transactions deemed comparable included Innovex/ADFlex Solutions, Tyco
International/ Raychem, Thomas & Betts/AFC Cable Systems, Tyco
International/AMP, Sanmina/Altron, Tyco International/Sigma Circuits,
Hadco/Continental Circuits, Applied Power/Versa Technologies, Sanmina/ Elexsys
International, Hadco/Zycon, Tyco International/Electrostar, Thomas & Betts/Augat
and Applied Power/Everest Electronic Equipment. The results of this analysis are
summarized in the table below:



                                                              AVERAGE (EXCLUDING
                                                                HIGH AND LOW)        HIGH       LOW
                                                              ------------------   --------   --------
                                                                                     
Trailing 12 Months Revenues.................................           1.3x           2.1x        .4x
Trailing 12 Months EBITDA...................................           9.2x          14.0x       4.9x
Trailing 12 Months EBIT.....................................          14.1x          29.3x       5.6x
Trailing 12 Months Net Income...............................          22.7x          52.3x       6.5x
One Trading Day Premium.....................................            13%            42%       (5)%
Twenty Trading Day Premium..................................            32%            89%         1%


All multiples for the transactions used in this analysis were based on public
information without taking into account different market and other conditions
during the periods when the selected representative transactions occurred.

    Applying the average multiples listed above to the trailing twelve months
financial results of Aavid as of July 3, 1999 pro forma for the Thermalloy
Acquisition as if it had occurred at the beginning of the period, and excluding
the estimated financial impact of transactions with Intel for discontinued
products as being unrepresentative of the continuing business of Aavid,
indicated an implied range of equity value per share for Aavid of $16.74 to
$28.75. Applying the average one trading day and twenty trading day premiums for
the selected transactions indicated by this analysis to Aavid's historical share
prices indicated an implied equity value per share of Aavid of $23.60 and
$26.73, respectively. These values were compared to an equity value per share of
Aavid Common Stock in the transaction of $25.50 as of August 18, 1999, subject
to the successful completion of the Thermalloy Acquisition, and Aavid's closing
price per share of $20.81 on August 18, 1999.

    Hambrecht & Quist noted that no company or transaction used in the above
analyses is identical to Aavid or the proposed transaction. Accordingly, an
analysis of the results of the foregoing is not simply mathematical; rather it
requires complex qualitative considerations and judgments concerning differences
in financial and operating characteristics of the companies and other factors
that could affect the public trading values of the companies or company to which
they are compared.

    DISCOUNTED CASH FLOW ANALYSIS.  Hambrecht & Quist analyzed the theoretical
valuation of Aavid based on the present value of its projected future cash
flows. To estimate the total present value of Aavid's business as of July 3,
1999, before giving effect to its capital structure, on a pro forma basis to
give effect to the Thermalloy Acquisition, Hambrecht & Quist discounted to the
present the projected stream of after-tax cash flows for Aavid through the year
ending December 31, 2003 and a terminal value based on multiples of Aavid's
projected calendar year 2003 EBITDA. In this analysis, Hambrecht & Quist used
discount rates ranging from 21.0% to 27.0% and multiples for the terminal value
of the business ranging from 6.0 to 8.0 times projected 2003 EBITDA.

    Based on these parameters, Hambrecht & Quist determined the implied equity
value per share of Aavid Common Stock pro forma for the Thermalloy Acquisition
to be in the range of $17.50 to $30.16.

                                       50

These values were compared to an equity value per share of Aavid Common Stock in
the transaction of $25.50 as of August 18, 1999, subject to the successful
completion of the Thermalloy Acquisition, and Aavid's closing price per share of
$20.81 on August 18, 1999.

    Financial projections used by Hambrecht & Quist in this analysis were based
on Aavid's estimates. Hambrecht & Quist makes no representations as to the
accuracy or attainability of the projections for the future performance of Aavid
used in this analysis.

    PRESENT VALUE OF POTENTIAL FUTURE SHARE PRICES.  Hambrecht & Quist
calculated the implied present equity value per share of Aavid Common Stock
based on internal and, where available, Wall Street, earnings per share
estimates for the years 1999, 2000 and 2001, forward P/E multiples ranging from
13x to 19x, and an equity discount rate range of 20% to 26%. Based on these
parameters and on management estimates for Aavid pro forma for the Thermalloy
Acquisition, Hambrecht & Quist determined the implied equity value per share of
Aavid Common Stock to be in the range of $16.77 to $29.56. These values were
compared to an equity value per share of Aavid Common Stock in the transaction
of $25.50 as of August 18, 1999, subject to the successful completion of the
Thermalloy Acquisition, and Aavid's closing price per share of $20.81 on
August 18, 1999.

    Financial projections used by Hambrecht & Quist in this analysis were based
on Aavid's and Wall Street estimates. Hambrecht & Quist makes no representations
as to the accuracy or attainability of the projections for the future
performance of Aavid used in this analysis.

    IMPLIED PREMIUMS ANALYSIS.  Hambrecht & Quist examined the trading history
of Aavid Common Stock. The trading range in the three months prior to
August 18, 1999 was $18.56 to $24.50 and in the nine months prior to August 18,
1999 was $12.00 to $24.50. Hambrecht & Quist also calculated the implied
premiums based on the $25.50 per share offer. The implied premiums are:



PERIOD                                                        $25.50 OFFER

Closing Price on 8/18/99....................................      22.5%
1 Week Average..............................................      23.7%
1 Month Average.............................................      26.2%
3 Month Average.............................................      21.5%
6 Month Average.............................................      39.5%
12 Month Average............................................      53.9%


    LEVERAGED BUYOUT ANALYSIS.  Based on the aggregate cash merger consideration
payable in the Merger, Hambrecht & Quist calculated the internal rate of return
for Willis Stein based on representative leveraged buyout capital structures and
using a terminal value based on a 2003 Exit EBITDA multiple range of a 6.0-9.0x.
Based on these parameters and on management estimates for Aavid pro forma for
the Thermalloy Acquisition, a purchase price of $25.50 implies an internal rate
of return for Willis Stein of 24.1% to 39.5%.

                                       51

    Pursuant to an engagement letter dated April 28, 1999, Aavid has agreed to
pay Hambrecht & Quist a fee of $500,000 in connection with the delivery of the
fairness opinion rendered on August 22, 1999. Upon consummation of the proposed
transaction, Aavid has agreed to pay Hambrecht & Quist a fee of 0.75% of the
aggregate consideration paid in the transaction, less the fee paid in connection
with the delivery of the fairness opinion and any other fees previously paid.
Aavid also has agreed to reimburse Hambrecht & Quist for its reasonable
out-of-pocket expenses and to indemnify Hambrecht & Quist against certain
liabilities, including liabilities under the federal securities laws or relating
to or arising out of Hambrecht & Quist's engagement as financial advisor.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

    The following discussion describes material United States federal income tax
consequences relevant to the Merger. The discussion is based on the Internal
Revenue Code of 1986, as amended, existing and proposed Treasury regulations,
rulings, administrative pronouncements and judicial decisions, changes to which
could materially affect the tax consequences described herein and could be made
on a retroactive basis.

    The receipt of cash in exchange for shares of Aavid Common Stock pursuant to
the Merger will be a taxable transaction for federal income tax purposes and
also may be a taxable transaction under applicable state, local and foreign
income and other tax laws. The tax consequences may vary depending upon, among
other things, your particular circumstances. In general, you will recognize a
gain or a loss for federal income tax purposes equal to the difference between
the adjusted tax basis of your Aavid Common Stock and the amount of cash
received in exchange for your Aavid Common Stock in the Merger. Such gain or
loss generally will be (a) calculated separately for each block of shares (I.E.,
shares acquired at the same cost in a single transaction) sold pursuant to the
Merger, (b) a capital gain or loss if the Aavid Common Stock is a capital asset
of yours and (c) a long-term gain or loss if the holding period for your Aavid
Common Stock is more than one year at the effective time of the Merger.

    Your receipt of cash pursuant to the Merger may be subject to backup
withholding at the rate of 31% unless you provide a certified taxpayer
identification number on Form W-9 and you otherwise comply with the backup
withholding rules or demonstrate an exemption from backup withholding. Backup
withholding is not an additional tax; any amounts withheld may be credited
against your federal income tax liability subject to the withholding.

    The foregoing discussion does not address all aspects of federal income
taxation that may be relevant to you and may not apply to you if you
(a) acquired your Aavid Common Stock pursuant to the exercise of employee stock
options or other compensation arrangements with Aavid, (b) are not a citizen or
resident of the United States, (c) exercise your dissenters' rights under
Delaware law or (d) are subject to special tax treatment under the Internal
Revenue Code (such as if you are a dealer in securities, a tax-exempt entity, an
insurance company, another financial institution, or a regulated investment
company or you hold your shares as part of a hedge, straddle, conversion or
other special transaction).

    This tax discussion is for your general information only. Due to the
individual nature of tax consequences, you are strongly urged to consult with
your tax advisor as to the specific tax consequences of the merger to you,
including the effects of applicable state, local or foreign income or other tax
laws or federal tax laws other than those pertaining to income tax.

REGULATORY MATTERS

    We must comply with the Hart-Scott-Rodino Antitrust Improvements Act of 1976
and the rules and regulations thereunder, which provide that certain acquisition
transactions may not be consummated until (1) certain information has been
furnished to the United States Antitrust Division

                                       52

of the Department of Justice and to the United States Federal Trade Commission
and (2) certain waiting periods have been terminated or have expired. Willis
Stein and Aavid filed Notification and Report Forms with the Antitrust Division
and the Federal Trade Commission on October 27, 1999. The waiting period under
the HSR Act was terminated on November 5, 1999.

    Despite the expiration of the Hart-Scott-Rodino waiting period, the
Antitrust Division, the Federal Trade Commission or any state may still
challenge the Merger on antitrust grounds. Any time before or after the
effective time of the Merger, the Antitrust Division, the FTC or any state could
take such action under the antitrust laws as it deems necessary or desirable in
the public interest. In addition, certain other persons, including private
parties, could take action under the antitrust laws and could seek to enjoin the
consummation of the Merger, to rescind the Merger or to seek divestiture of
Aavid or one or more of its businesses as a result of the Merger.

INTERESTS OF OUR OFFICERS AND DIRECTORS IN THE MERGER

    In considering the Aavid Board's recommendation, you should be aware that
our directors and executive officers, as well as several other members of our
senior management and other key employees, have interests in the transaction as
employees or directors that are different from, or in addition to, your
interests as stockholders. The Aavid Board knew about these different or
additional interests and considered them, among the other factors described in
this Proxy Statement, when it approved the Merger.

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS

    We or our subsidiaries are parties to employment agreements with
Messrs. Borelli, Boysan, Dannecker, Eldred, Mitchell and Patel, our executive
officers. These agreements require us to continue paying each executive his base
salary for the longer of 12 months (9 months in the case of Mr. Eldred) or the
remaining term of the employment agreement if we terminate the executive's
employment without "cause" (as defined in the employment agreements). In
addition, Mr. Patel may elect to terminate his employment and receive the same
payment in the following circumstances:

    - as a result of a merger, acquisition or financing, there is a material
      change in the make-up of our board of directors;

    - the material change in the make-up of our board of directors is not
      consented to by the executive; and

    - because of the material change in the make-up of our board of directors,
      he terminates his employment within 90 days of the change.

The employment agreements of Messrs. Borelli, Boysan, Dannecker, Eldred,
Mitchell and Patel currently expire on December 31, 1999, August 24, 2000,
June 30, 2000, September 1, 2001, December 5, 2001, and May 1, 2001,
respectively.

    In addition, our employment agreements with Messrs. Eldred and Mitchell
require us to make severance payments and provide other benefits if their
employment is terminated following a change in control. The completion of the
Merger will constitute a change in control for this purpose. Under these
agreements, if we terminate the employment of Messrs. Eldred or Mitchell without
"cause" (as defined in their employment agreements) or if Messrs. Eldred or
Mitchell terminates his employment for "good reason" (as defined in their
employment agreements) within three months following a change in control in the
case of Mr. Eldred, or six months following a change in control in the case of
Mr. Mitchell, we must provide the following benefits:

    - a lump-sum cash payment equal to two times the executive's current base
      salary, within 15 days following termination;

                                       53

    - a lump-sum cash bonus payment of $75,000 to Mr. Eldred within 15 days
      following termination;

    - continued participation in our welfare benefit plans, at our expense, for
      the executive and his dependents for two years following termination; and

    - executive outplacement services, office space and secretarial support
      services for 12 months following termination.

    If following the Merger the employment of all of our executive officers
terminates under circumstances requiring the payment of severance, we would be
obligated to pay them an aggregate of approximately $1,500,000 (excluding
payments to Mr. Borelli) and to continue to provide some of these officers with
benefits for up to two years. Mr. Borrelli has determined to step down as our
Chief Executive Officer when his employment expires on December 31, 1999,
whether or not the Merger has been consummated and will therefore not be
entitled to any severance payments. Mr. Borelli will remain as Chairman of the
Board and Bharatan Patel, our President and Chief Operating Officer, will become
our Chief Executive Officer.

STOCK AND OPTION OWNERSHIP

    At the time the Merger is completed, all options to purchase shares of Aavid
Common Stock will become fully vested and exercisable pursuant to the terms of
the plans under which such options were issued and convert into the right to
receive cash equal to the product of the number of shares subject to each option
times the excess, if any, of $25.50 per share over the exercise price per share
for such option. The following table sets forth information regarding (1) the
number of shares of Aavid Common Stock owned by each of our officers and
directors, (2) the number of options to purchase shares of Aavid Common Stock
owned by each of our directors and executive officers which have an exercise
price of less than $25.50 per share and (3) the average weighted exercise price
per share of the options held by such individual:



                                                           NUMBER OF   NUMBER OF   AVERAGE WEIGHTED
NAME                                                        SHARES      OPTIONS     EXERCISE PRICE

Ronald Borelli...........................................    20,000     406,250        $ 11.72

Frank Pipp...............................................        --       2,500        $ 20.875
David Steadman...........................................    31,000      12,500        $ 11.90


Our executive officers and directors will receive an aggregate of $10.5 million
from the cash-out of their options in the Merger.

INDEMNITY AND INSURANCE

    As described in "The Merger Agreement--Indemnification of Officers and
Directors," we and Holdings have agreed that the surviving corporation will
indemnify, subject to customary conditions, our officers and directors, for at
least six years after the Merger, against all damages and expenses they may
incur relating to their service as officers and directors, including matters
arising out of the Merger. In order to fulfill this obligation, for six years
after the Merger the certificate of incorporation and by-laws of the surviving
corporation must contain provisions limiting the liability of directors and
indemnifying officers and directors to the fullest extent permitted by law. In
addition, for six years after

                                       54

the Merger the surviving corporation must use its reasonable best efforts to
provide officers' and directors' liability insurance that covers acts or
omissions that occurred prior to the Merger and provides coverage and other
terms that are no less favorable than those provided by our current policy.
However, the surviving corporation is not obligated to spend more than 200% of
the amount of our current premium to obtain this insurance but must instead
obtain a policy with the greatest coverage available for a cost not exceeding
this amount.

EQUITY INTERESTS FOLLOWING THE MERGER

    Willis Stein has advised us that it typically makes available, to management
and key employees of its portfolio companies, up to 10% of the fully-diluted
common equity of the investment vehicle portfolio company and the opportunity to
co-invest in the common equity and any preferred stock of the investment vehicle
portfolio company on the same economic terms as Willis Stein. The common equity
made available to management and key employees generally does not have any value
until Willis Stein's preferred stock investment is returned. Our management and
key employees have not had any discussions with Willis Stein concerning any such
investment by them, and no agreements, arrangements or understandings have been
reached between Willis Stein and our management and key employees in this
regard.

DISSENTERS' APPRAISAL RIGHTS

    You have the right to dissent from the Merger and to demand and obtain cash
payment of the appraised value of your shares of Aavid Common Stock under the
circumstances described below. The appraised value that you obtain for your
shares by dissenting will be determined by a court and may be less than, equal
to or greater than the $25.50 per share cash merger consideration provided for
in the Merger Agreement. If you fail to comply precisely with the procedural
requirements of Section 262 of the Delaware General Corporation Law, you will
lose your right to dissent and seek payment of the appraised value of your
shares.

    The following is a summary of Section 262, which specifies the procedures
applicable to dissenting stockholders. This summary is not a complete statement
of the law regarding your right to dissent under Delaware law, and if you are
considering dissenting, we urge you to review the provisions of Section 262
carefully and to consult an attorney. The text of Section 262 is attached to
this Proxy Statement as APPENDIX C, and we incorporate that text into this Proxy
Statement by reference. Among other matters, you should be aware of the
following:

    - to be entitled to dissent and seek appraisal, you must hold shares of
      Aavid Common Stock on the date you make the demand required under Delaware
      law, you must continuously hold those shares until the Merger has been
      completed, you must not vote in favor of the Merger and you must otherwise
      comply with the requirements of Section 262;

    - before the Special Meeting, you must deliver a written notice that states
      your identity and your intent to demand appraisal to Aavid Thermal
      Technologies, Inc., One Eagle Square, Concord, New Hampshire 03301,
      Attention: General Counsel (you should be aware that simply voting against
      the Merger or not voting is not a demand for appraisal rights);

    - within ten days after the effective time of the Merger, the surviving
      corporation will notify all of the dissenting Aavid stockholders who have
      complied with Section 262 and who have not voted in favor of the Merger;

    - within 120 days after the effective time of the Merger, the surviving
      corporation, you or any other stockholder who has complied with the
      requirements of Section 262 may file a petition in the Delaware Court of
      Chancery demanding a determination of the value of the stock of the
      dissenting stockholders; if a petition isn't filed within this time
      period, dissenting stockholders

                                       55

      will lose their right to an appraisal and will be entitled to receive only
      the cash merger consideration;

    - the Court of Chancery will determine which dissenting stockholders
      complied with the requirements of Section 262 and are entitled to
      appraisal rights;

    - the Court of Chancery will then appraise the shares, determining their
      fair value exclusive of any value arising from the accomplishment or
      expectation of the Merger, together with a fair rate of interest, if any,
      to be paid on the appraised fair value; the Court of Chancery will
      consider all relevant factors in determining the fair value and the fair
      interest rate (if any);

    - the Court of Chancery will then direct the surviving corporation to pay
      the fair value of the dissenting shares, together with any interest, to
      the stockholders entitled to payment; payment will be made when the
      stockholder surrenders the certificates to the surviving corporation;

    - the costs of the proceeding for appraising the fair value may be
      determined by the court and the court may require the parties to bear the
      costs in any manner that the court believes to be equitable;

    - the court may require, upon a dissenting stockholder's request, that all
      or a portion of the expenses incurred by that stockholder in connection
      with the appraisal, including attorney's and expert's fees, be borne pro
      rata by all of the dissenting stockholders;

    - if you dissent from the Merger, you will not be entitled to vote your
      shares of Aavid Common Stock for any purpose or to receive dividends or
      other distributions (other than dividends or other distributions payable
      to stockholders of record at a date prior to the effective time of the
      Merger) after the effective time of the Merger; and

    - you may withdraw your demand for appraisal and accept the $25.50 per share
      cash merger consideration provided for in the Merger Agreement at any time
      within 60 days after the effective date of the Merger or after that date
      with the surviving corporation's consent.

                                       56

                              THE MERGER AGREEMENT

    WE HAVE SUMMARIZED THE MATERIAL PROVISIONS OF THE MERGER AGREEMENT BELOW. A
COPY OF THE MERGER AGREEMENT IS ATTACHED TO THIS PROXY STATEMENT AS APPENDIX A.
WE URGE YOU TO READ THE MERGER AGREEMENT CAREFULLY BEFORE DECIDING HOW TO VOTE
YOUR SHARES.

THE MERGER

    In the Merger Agreement, we have agreed that, if the Merger Agreement is
approved by the Aavid stockholders and the other conditions to the Merger are
satisfied or waived, MergerCo will be merged with and into Aavid, with Aavid
surviving the merger as a direct, wholly-owned subsidiary of Holdings. When we
refer to the "surviving corporation" in this Proxy Statement, we mean Aavid as
it will exist after the Merger. After the Merger, all of Aavid's and MergerCo's
rights, privileges, powers and franchises, and all of their restrictions,
disabilities and duties, will be those of the surviving corporation. Aavid
Common Stock, all of which will be owned directly or indirectly by Holdings,
will be delisted from the Nasdaq National Market and deregistered under the
Securities Exchange Act of 1934 and will no longer be publicly traded.

EFFECTIVE TIME OF THE MERGER

    The Merger will occur at the time we file a certificate of merger with the
Secretary of State of the State of Delaware, unless we and Holdings agree to
specify in the certificate of merger that the Merger will occur at some other
time. The certificate of merger will be filed on the closing date of the Merger,
which will occur as promptly as practicable after the Merger Agreement has been
approved by the Aavid stockholders and the other conditions to the Merger have
been satisfied or waived, unless we agree with Holdings to complete the
transaction on another date. When we refer to the "effective time" of the Merger
in this Proxy Statement, we mean the date and time when the Merger becomes
effective, as described in this paragraph.

MERGER CONSIDERATION

    AAVID COMMON STOCK.  At the effective time of the Merger, each issued and
outstanding share of Aavid Common Stock will be converted into the right to
receive $25.50 in cash, without interest.

    Some shares of Aavid Common Stock will not be converted in the Merger. These
shares include shares owned by Holdings or MergerCo or held by Aavid in its
treasury, which will be canceled at the effective time of the Merger without any
payment. In addition, shares owned by Aavid stockholders who have demanded
appraisal rights in compliance with Delaware law will not be converted in the
Merger. See "The Merger--Dissenters' Appraisal Rights" above.

    AAVID STOCK OPTIONS.  At the effective time of the Merger, all outstanding
options to purchase shares of Aavid Common Stock will be canceled. Each holder
of an option, regardless of whether the option is fully vested or exercisable,
will be entitled to receive cash in the amount of (1) $25.50 minus the per share
exercise price of the option times (2) the number of shares subject to the
option immediately prior to the effective time, assuming the option was fully
vested and exercisable.

    AAVID WARRANTS.  At the effective time of the Merger, all outstanding
warrants or similar rights to purchase or acquire shares of Aavid Common Stock
will be converted into the right to receive cash in the amount of (1) $25.50
minus the per share exercise price of the warrant times (2) the number of shares
subject to the warrant immediately prior to the effective time. Any warrants
with a per share exercise price of $25.50 or more will be canceled at the
effective time of the Merger without any payment.

                                       57

    AAVID 1995 EMPLOYEE STOCK PURCHASE PLAN.  We have agreed to terminate our
1995 Employee Stock Purchase Plan on or before the closing date of the Merger.
On the closing date, all accumulated employee salary deductions will be applied
to purchase whole shares of Aavid Common Stock under the plan, and any remaining
employee salary deductions will be returned to the participants without
interest. At the effective time of the Merger, each share of Aavid Common Stock
purchased under the plan will be converted into the right to receive $25.50 per
share in cash.

PAYMENT FOR SHARES

    HOW TO RECEIVE PAYMENT.  Prior to the effective time of the Merger, Holdings
will appoint a bank or trust company reasonably satisfactory to us as the paying
agent. Promptly after the effective time of the Merger, the paying agent will
mail a letter of transmittal and other instructional materials to you and the
other Aavid stockholders. The letter of transmittal and other materials will
tell you how to surrender your Aavid Common Stock certificates in exchange for
the $25.50 per share cash merger consideration. You will not be entitled to
receive the cash merger consideration until you send your Aavid Common Stock
certificates to the paying agent, along with a properly completed and signed
letter of transmittal. Holdings has agreed to provide the paying agent with the
cash necessary to pay the cash merger consideration to each holder of Aavid
Common Stock.

    YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD.
YOU SHOULD ALSO NOT SEND YOUR STOCK CERTIFICATES TO US OR TO HOLDINGS. PLEASE
KEEP YOUR STOCK CERTIFICATES UNTIL YOU RECEIVE A LETTER OF TRANSMITTAL FROM THE
PAYING AGENT AFTER THE EFFECTIVE TIME OF THE MERGER, AND FOLLOW THE INSTRUCTIONS
CONTAINED IN THE LETTER OF TRANSMITTAL.

    TRANSFER OF SHARES.  If your shares are held in a name other than the name
registered in our transfer records, you will have to provide the paying agent
with evidence that the shares have been transferred and that any applicable
transfer taxes have been paid.

    Our transfer records will close, and we will not register transfers of
shares of Aavid Common Stock on our books, after the effective time of the
Merger. If shares are presented for transfer after that time, they will be
surrendered and canceled, and the cash merger consideration will be paid to the
person who is registered as the holder of the shares on our books.

    LOST, STOLEN OR DESTROYED CERTIFICATES.  If you have lost a certificate, or
if your certificate has been stolen or destroyed, in order to receive the cash
merger consideration you will have to sign an affidavit stating that your
certificate was lost, stolen or destroyed. In addition, if the surviving
corporation requires, you may have to post a bond indemnifying the surviving
corporation against any claims made against it with respect to the lost, stolen
or destroyed certificate.

    TAX WITHHOLDING.  Holdings or the surviving corporation will deduct and
withhold from the cash merger consideration any amounts that it is required to
deduct and withhold under applicable tax law. All amounts so withheld will be
treated for all purposes of the Merger Agreement as having been paid to the
applicable Aavid stockholder.

    UNCLAIMED CASH MERGER CONSIDERATION.  Nine months after the closing date of
the Merger, the paying agent will deliver to the surviving corporation any
amount of the cash merger consideration that has not been paid to the former
stockholders of Aavid. After that time, the former stockholders of Aavid will
have to surrender their certificates to the surviving corporation to receive the
cash merger consideration. Any such stockholder will be deemed a general
creditor of the surviving corporation for such purpose. Any amount of the cash
merger consideration that has not been claimed by the former stockholders of
Aavid two years after the closing date of the Merger, or immediately prior to
the time when it would become the property of any governmental entity, shall, to
the extent permitted by applicable law, become the property of the surviving
corporation. Neither Holdings, the surviving corporation nor the paying agent
will be liable to any former Aavid stockholder for any amount of the

                                       58

cash merger consideration properly delivered to a public official under any
abandoned property, escheat or similar law.

CONDITIONS TO THE MERGER

    Various conditions must be satisfied before we and Holdings complete the
Merger. Some of these conditions apply to both us and Holdings, which means
that, if the conditions are not met, neither we nor Holdings will have an
obligation to complete the Merger. Other conditions apply only to Holdings,
which means that, if the conditions are not met, we will have an obligation to
complete the Merger but Holdings will not. Certain conditions, primarily related
to our completion of the acquisition of the Thermalloy Division, have already
been satisfied and therefore are not discussed below.

    CONDITIONS THAT APPLY TO BOTH US AND HOLDINGS.  Neither we nor Holdings will
have an obligation to complete the Merger unless the following conditions are
satisfied:

    - the Merger Agreement has been approved by Aavid stockholders holding a
      majority of the outstanding shares of Aavid Common Stock;

    - the waiting period applicable to the Merger under the Hart-Scott-Rodino
      Antitrust Improvements Act of 1976 has expired or been terminated;

    - no judgment, injunction, order or decree and no provision of any law or
      regulation prohibits the completion of the Merger; and

    - all actions by or filings with any governmental body necessary to permit
      completion of the Merger have been taken or made.

    CONDITIONS THAT APPLY ONLY TO HOLDINGS.  Holdings will not have an
obligation to complete the Merger unless the following additional conditions are
also satisfied:

    - we have performed in all material respects the obligations that we are
      required under the Merger Agreement to perform prior to the effective time
      of the Merger;

    - our representations and warranties in the Merger Agreement that are
      qualified by "Material Adverse Effect" or similar terms are true and
      correct in all respects as of the date of the Merger Agreement and as of
      the closing date of the Merger; and

    - our representations and warranties in the Merger Agreement that are not
      qualified by "Material Adverse Effect" or similar terms are true and
      correct in all material respects as of the date of the Merger Agreement
      and as of the closing date of the Merger.

    BECAUSE OF THESE CONDITIONS, EVEN IF THE AAVID STOCKHOLDERS APPROVE THE
MERGER, THE MERGER MAY NOT OCCUR.

    - except for normal increases in the ordinary course of business consistent
      with past practice, increase the compensation or fringe benefits of any
      director, officer or employee or pay any benefit not required by any
      existing plan or arrangement;

                                       61

    - revalue any assets in any material respect;

    - pay, discharge or satisfy any material claims, liabilities or obligations,
      other than liabilities reflected or reserved against in our consolidated
      financial statements or incurred since the date of our consolidated
      financial statements in the ordinary course of business and consistent
      with past practice;

    - make any tax election or settle or compromise any material income tax
      liability;

    - other than in the ordinary course of business and consistent with past
      practice, take any action with respect to accounting policies or
      procedures, other than a change in accounting policies that is not
      material to us and our subsidiaries taken as a whole and is required by
      Securities and Exchange Commission regulations or a change in generally
      accepted accounting principles;

    - take or agree to take any action that would make any of our
      representations and warranties in the Merger Agreement inaccurate; or

    - amend, waive or otherwise alter any provision of the stock purchase
      agreement relating to our acquisition of the Thermalloy Division.

OTHER ACQUISITION PROPOSALS

    In the Merger Agreement we agreed with Holdings that we would not, and would
not authorize or permit our officers, directors, agents, representatives,
advisors or subsidiaries to:

    - solicit, initiate or take any action to knowingly facilitate an
      Acquisition Proposal (as described below) or agree to or endorse an
      Acquisition Proposal;

    - enter into or participate in any discussions or negotiations regarding an
      Acquisition Proposal or otherwise cooperate in any way with or knowingly
      assist or participate in, facilitate or encourage an Acquisition Proposal;
      or

    - grant any waiver or release under any standstill or similar agreement
      relating to our equity securities or those of our subsidiaries.

    However, the Merger Agreement does not prohibit us from taking any of the
following actions to the extent that the Aavid Board concludes in good faith,
based on the advice of outside counsel, that the action is necessary in order to
comply with the Board's fiduciary duties to the Aavid stockholders under law:

    - furnishing information to a party who has made or is seeking to initiate
      discussions with respect to an Acquisition Proposal, as long as that party
      enters into a confidentiality agreement that is not less favorable to us
      than the confidentiality agreement we entered into with Willis Stein;

    - engaging in discussions or negotiations with a party who has made a bona
      fide Acquisition Proposal;

    - taking and disclosing to our stockholders a position with respect to an
      Acquisition Proposal we have received, as required by Securities and
      Exchange Commission rules; and

    - withdrawing or modifying our recommendation that you and the other Aavid
      stockholders approve the Merger and the Merger Agreement, if we have
      received an Acquisition Proposal.

    The Merger Agreement also permits us to take any action a final,
non-appealable order of a court of competent jurisdiction orders us to take.

    An "Acquisition Proposal" means any inquiry, proposal or offer that
constitutes or is reasonably likely to lead to:

    - any acquisition or purchase of 30% or more of our consolidated assets or
      more than 30% of any class of our or our subsidiaries' equity securities;

                                       62

    - any tender offer or exchange offer that would result in any third party
      beneficially owning 30% or more of any class of our or our subsidiaries'
      equity securities;

    - any merger, consolidation, business combination, sale of substantially all
      assets, recapitalization, liquidation, dissolution or similar transaction
      involving us or any of our subsidiaries whose assets constitute more than
      30% of our consolidated assets (other than the Merger contemplated by the
      Merger Agreement); or

    - any other transaction, other than the acquisition of the Thermalloy
      Division, which would reasonably be expected to materially interfere with,
      prevent or materially delay the Merger or which would reasonably be
      expected to materially dilute the benefits to Holdings of the transactions
      contemplated by the Merger Agreement.

    We have agreed to promptly notify Holdings of the terms and conditions of
any Acquisition Proposal we receive and of the identity of the person making the
Acquisition Proposal. We have also agreed that we will not enter into a
definitive agreement relating to an Acquisition Proposal until two business days
after Holdings receives our notification.

    We are permitted to terminate the Merger Agreement to enter into a
definitive agreement with respect to an Acquisition Proposal as long as we pay
Holdings a fee of $8.3 million as more fully described below under "Termination
of the Merger Agreement".

INDEMNIFICATION OF OFFICERS AND DIRECTORS

    The Merger Agreement provides that the surviving corporation will indemnify
our present and former officers and directors, for at least six years after the
effective time of the Merger, against all damages and expenses they may incur in
connection with any claim, suit or investigation relating to their service as an
officer or director of us or any of our subsidiaries, including matters related
to the Merger. This indemnification obligation covers any matter that existed or
occurred prior to the effective time of the Merger, even if the matter was
claimed or asserted after the effective time of the Merger. The surviving
corporation must also indemnify and hold harmless Holdings and any of its
stockholders, officers, directors or affiliates against any losses they may
incur in connection with any litigation arising out of the transactions
contemplated by the Merger Agreement.

    For six years after the effective time of the Merger, the surviving
corporation will use its reasonable best efforts to provide officers' and
directors' liability insurance for those persons currently covered by our
officers' and directors' liability insurance, relating to acts or omissions that
occurred prior to the effective time of the Merger. This insurance policy must
provide an amount of coverage and contain other terms that are no less favorable
than those provided by our policy in effect on the date of the Merger Agreement.
However, if the premium for this policy exceeds 200% of the premium we paid in
1998, the surviving corporation is not obligated to purchase the same level of
coverage but must instead obtain a policy with the greatest coverage available
for a cost not exceeding 200% of the premium we paid in 1998.

    In addition, for a period of six years after the effective time of the
Merger, the certificate of incorporation and by-laws of the surviving
corporation and its subsidiaries will contain provisions limiting the liability
of directors and indemnifying officers and directors to the fullest extent
permitted by law. Unless required by law, these provisions may not be amended in
any manner which is materially adverse to our officers and directors without
their prior written consent. If the surviving corporation consolidates with or
merges into any other entity or transfers all or substantially all of its
assets, proper provisions must be made so that the successors and assigns of the
surviving corporation assume the indemnification obligations described in the
Merger Agreement.

                                       63

OTHER AGREEMENTS

    In the Merger Agreement, we, Holdings and MergerCo also made agreements
relating to other matters. We agreed to call and hold a meeting of our
stockholders to vote on the Merger, to file and clear this Proxy Statement with
the Securities and Exchange Commission and to provide Holdings with access to
our books, records, personnel, offices, facilities and properties. Holdings and
MergerCo agreed to obtain all financing necessary to pay the cash merger
consideration. We, Holdings and MergerCo agreed to use our reasonable best
efforts to make and obtain all filings, consents, approvals, permits,
authorizations and waivers needed in order to complete the Merger and to consult
with each other before issuing any press release or making any public statement
or filing relating to the Merger or the Merger Agreement. We and Holdings also
agreed that, if we terminated the stock purchase agreement relating to our
acquisition of the Thermalloy Division without completing the acquisition, the
cash merger consideration would be reduced to $24.50 per share, and MergerCo
would have the right, and would be obligated if we so requested, to commence a
public tender offer to purchase all of the outstanding shares of Aavid Common
Stock for a purchase price of $24.50 per share in cash.

TERMINATION OF THE MERGER AGREEMENT

    We, Holdings and MergerCo may terminate the Merger Agreement by mutual
written consent at any time. In addition, either we or Holdings may terminate
the Merger Agreement at any time prior to the effective time of the Merger,
whether before or after approval of the Merger Agreement by the Aavid
stockholders, in the circumstances described below.

    TERMINATION BY US OR HOLDINGS.  Either we or Holdings may terminate the
Merger Agreement:

    - if any law or regulation makes completion of the Merger illegal or any
      final and nonappealable judgment, injunction, order or decree enjoins us
      or Holdings from completing the Merger; or

    - if the Merger has not been completed by March 31, 2000 or the Aavid
      stockholders do not approve the Merger.

    TERMINATION BY US.  We may terminate the Merger Agreement if the Aavid Board
determines in good faith, after reviewing the advice of its financial advisor,
that an Acquisition Proposal that is reasonably capable of being financed is
more favorable to the Aavid stockholders than the Merger, and

    - we have complied with our obligations described above under the caption
      "Other Acquisition Proposals",

    - we pay the $8.3 million termination fee described below under the caption
      "Termination Fee" and

    - we enter into a definitive agreement to complete the more favorable
      Acquisition Proposal.

    Because we did not mail this Proxy Statement to our stockholders by
November 30, 1999 we would have had the right to terminate the Merger Agreement
if we had requested Hambrecht & Quist, our financial advisor, to bring-down its
fairness opinion and, in response, Hambrecht & Quist had advised us in writing
that it could no longer issue its opinion that the cash merger consideration is
fair to the Aavid stockholders from a financial point of view.

    TERMINATION BY HOLDINGS.  Holdings may terminate the Merger Agreement:

    - if the Aavid Board withdraws or materially modifies its approval of the
      Merger or its recommendation of the Merger to the Aavid stockholders or
      fails, as a result of the exercise of its fiduciary duties, to take action
      required to be taken by the Merger Agreement; or

                                       64

    - if any of the following conditions exist:

       - a governmental authority or any other person institutes an action or
         proceeding which, in Holdings' reasonable judgment, is likely to result
         in:

           - challenging, making illegal, materially delaying or prohibiting the
             Merger or seeking material damages;

           - prohibiting Holdings' ownership or operation of a material portion
             of our assets or compelling Holdings to dispose of a material
             portion of our assets;

           - imposing material limitations on Holdings' ability to exercise full
             rights of ownership of the Aavid Common Stock; or

           - requiring Holdings to divest any shares of Aavid Common Stock;

       - an event occurs, or a condition that existed on the date of the Merger
         Agreement worsens, which event or condition, by itself or together with
         other events or conditions, has had or could reasonably be expected to
         have a material adverse effect on our business, operations, prospects
         (excluding the prospects of our industry or the economy as a whole),
         financial condition or assets;

       - another person makes a tender or exchange offer for more than 30% of
         the Aavid Common Stock at a price greater than $25.50 per share; or any
         person or group acquires beneficial ownership or the right to acquire
         beneficial ownership of more than 30% of the Aavid Common Stock, except
         as disclosed in Schedules 13D or 13G filed with the Securities and
         Exchange Commission before August 24, 1999 or for arbitrage purposes;
         or any person or group that had disclosed beneficial ownership of 5% or
         more of the Aavid Common Stock prior to August 24, 1999 acquires
         beneficial ownership, or the right to acquire beneficial ownership, of
         an additional 10% or more of the Aavid Common Stock; or any person or
         group enters into an agreement in principle or a definitive agreement
         regarding a merger, consolidation or other business combination with
         us;

       - we breach in any material respect any of our agreements under the
         Merger Agreement; or

       - any of our representations and warranties made in the Merger Agreement
         is not true in any material respect.

Holdings would also have had the right to terminate the Merger Agreement:

    - if we had failed to call the Special Meeting to vote on the Merger within
      a reasonable time after the Securities and Exchange Commission had
      completed its review of this Proxy Statement and after the completion of
      our acquisition of the Thermalloy Division or the termination of the stock
      purchase agreement relating to our acquisition of the Thermalloy Division,
      or if we had failed to mail this Proxy Statement to our stockholders as
      promptly as reasonably practicable thereafter or if we had not included in
      this Proxy Statement the recommendation of our board of directors that our
      stockholders vote in favor of the Merger; or

    - if we had amended or waived any provision of the stock purchase agreement
      relating to our acquisition of the Thermalloy Division.

TERMINATION FEE

    We have agreed to pay Holdings a termination fee of $8.3 million if the
Merger does not occur due to one of the reasons described below.

    TERMINATION BY HOLDINGS.  We will pay Holdings the termination fee if
Holdings terminates the Merger Agreement because our board of directors has
withdrawn or materially modified its approval of

                                       65

the Merger or its recommendation of the Merger to the Aavid stockholders or has
failed, as a result of the exercise of its fiduciary duties, to take action
required to be taken by the Merger Agreement. We also would have been obligated
to pay Holdings the termination fee if Holdings had terminated the Merger
Agreement because we had failed to call the Special Meeting to approve the
Merger, had failed to mail this Proxy Statement or had failed to recommend the
Merger to our stockholders as described above under "Termination of the Merger
Agreement."

    TERMINATION BY US.  We will pay Holdings the termination fee if we terminate
the Merger Agreement because our board of directors has determined in good
faith, after reviewing the advice of its financial advisor, that an Acquisition
Proposal that is reasonably capable of being financed is more favorable to the
Aavid stockholders than the Merger and we are entering into a definitive
agreement to complete the more favorable Acquisition Proposal. We also would
have been obligated to pay Holdings the termination fee if we had terminated the
Merger Agreement because we had not mailed this Proxy Statement by November 30,
1999 and Hambrecht & Quist, our financial advisor, was not able to deliver,
following our request after that date, a bring-down of its fairness opinion, as
described above under "Termination of the Merger Agreement."

    ACQUISITION PROPOSAL.  We will also pay Holdings the termination fee if:

    - an Acquisition Proposal is made after the date of the Merger Agreement;

    - the Merger Agreement is terminated because the Merger has not been
      consummated by March 31, 2000 or is not approved by our stockholders; and

    - within nine months of the termination of the Merger Agreement, any of the
      following events occurs (or, within six months after the Merger Agreement
      is terminated, we enter into a definitive agreement that is subsequently
      completed regarding one of these events) in which the Aavid stockholders
      receive cash, securities or other consideration having an aggregate value,
      together with any shares of Aavid Common Stock held by them after
      completion, in excess of the cash merger consideration:

       - we are acquired, by merger or otherwise;

       - a third party acquires more than 50% of our assets and those of our
         subsidiaries, taken as a whole;

       - a third party acquires more than 50% of the outstanding Aavid Common
         Stock; or

       - we adopt and implement a plan of liquidation, recapitalization or share
         repurchase or an extraordinary dividend relating to more than 50% of
         the outstanding Aavid Common Stock or to 50% of our assets and those of
         our subsidiaries, taken as a whole.

EXPENSE REIMBURSEMENT

    In general, we and Holdings will each pay our own fees and expenses incurred
in connection with the Merger. We have agreed to reimburse Holdings and its
affiliates for up to $1.5 million of their out-of-pocket fees and expenses
incurred in connection with the Merger Agreement if the Merger Agreement is
terminated because:

    - we have breached or failed to perform in any material respect any of our
      agreements under the Merger Agreement, and the breach has not been cured
      within a reasonable period of time after Holdings notifies us of the
      breach;

    - any of our representations and warranties in the Merger Agreement are not
      true in any material respect when made or at any time prior to completion
      of the Merger (except for representations and warranties made as of a
      specific date, which must be true and correct in all material

                                       66

      respects as of that date) and the misrepresentation has not been cured
      within a reasonable period of time after Holdings notifies us of the
      misrepresentation; or

    - we have amended or waived any provision of the stock purchase agreement
      relating to our acquisition of the Thermalloy Division.

AMENDMENT

    To the extent permitted by law, we, Holdings and MergerCo may amend the
Merger Agreement at any time. After adoption of the Merger Agreement by the
Aavid stockholders, however, no amendment can be made without the further
approval of the Aavid stockholders if the amendment decreases the $25.50 per
share cash merger consideration, adversely affects the rights of the Aavid
stockholders or otherwise requires by law the approval of the Aavid
stockholders.

EXTENSION; WAIVER

    At any time prior to the effective time of the Merger, we, Holdings or
MergerCo may extend the time for performance of any obligations, waive any
inaccuracies in the representations and warranties or waive compliance with any
of the agreements or conditions contained in the Merger Agreement.

VOTING AGREEMENTS

    Certain of our directors and officers, who together beneficially own 360,565
shares of outstanding Aavid Common Stock, or approximately 3.8% of the
outstanding shares of Aavid Common Stock on the record date, have entered into
voting agreements with Holdings. Under the voting agreements, the stockholders
agreed to vote all shares of Aavid Common Stock owned or subsequently acquired
by them in favor of the Merger and against any other proposal that would prevent
or materially delay the Merger or materially dilute the benefits of the Merger
to Holdings. The stockholders also agreed not to sell, assign, transfer or
encumber the shares of Aavid Common Stock owned or subsequently acquired by
them, except as permitted by the voting agreements. The voting agreements will
automatically terminate when the Merger Agreement terminates, including if the
Merger Agreement is terminated in connection with our accepting another
acquisition proposal as discussed above under "The Merger Agreement--Other
Acquisition Proposals".

                                       67

    completion of the Merger. The directors and executive officers in this
    group, who together beneficially own 360,188 shares of outstanding Aavid
    Common Stock, or approximately 3.8% of the outstanding shares of Aavid
    Common Stock at November 30, 1999, have agreed to vote all shares of Aavid
    Common Stock owned or subsequently acquired by them in favor of the Merger.
    Because shares of Aavid Common Stock subject to options currently
    exercisable or exercisable within 60 days of November 30, 1999 are deemed
    outstanding for purposes of computing the percentage ownership of the person
    holding such options but are not deemed outstanding for the purpose of
    computing the percentage ownership of any other person, all directors and
    executive officers as a group beneficially own more shares, but have a
    smaller percentage ownership interest, than Mr. Beane.

                          AGREEMENT AND PLAN OF MERGER

    AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of August 23,
1999, between Heat Holdings Corp., a Delaware corporation ("Purchaser"), Heat
Merger Corp., a Delaware corporation and a wholly owned subsidiary of Purchaser
("Merger Sub"), and Aavid Thermal Technologies, Inc., a Delaware corporation
(the "Company").

                                    RECITALS

    WHEREAS, the Boards of Directors of Purchaser and the Company each have
determined that it is in the best interests of their respective companies and
stockholders for Purchaser to acquire the Company upon the terms and subject to
the conditions set forth in this Agreement.

    WHEREAS, the parties to this Agreement desire to make certain
representations, warranties, covenants and agreements in connection herewith.

    NOW, THEREFORE, in consideration of the foregoing, and of the
representations, warranties, covenants and agreements contained in this
Agreement, the parties to this Agreement hereby agree as follows:

                                   ARTICLE 1
                                   THE MERGER

    1.1.  THE MERGER.  Subject to the terms and conditions of this Agreement, at
the Effective Time (as defined in Section 1.3), Merger Sub shall be merged with
and into the Company in accordance with this Agreement and the applicable
provisions of the General Corporation Law of the State of Delaware (the "DGCL"),
and the separate corporate existence of Merger Sub shall thereupon cease (the
"Merger"). The Company shall be the surviving corporation in the Merger
(sometimes hereinafter referred to as the "Surviving Corporation"). The Merger
shall have the effects specified in the DGCL.

    1.2.  THE CLOSING.  Subject to the terms and conditions of this Agreement,
the closing of the Merger (the "Closing") shall take place at the offices of
Bartlit Beck Herman Palenchar & Scott, 54 W. Hubbard Street, Chicago, Illinois,
at 10:00 a.m., local time, as soon as practicable following the satisfaction (or
waiver if permissible) of the conditions set forth in Article 9. The date on
which the Closing occurs is hereinafter referred to as the "Closing Date."

    1.3.  EFFECTIVE TIME.  If all the conditions to the Merger set forth in
Article 9 shall have been fulfilled or waived in accordance with this Agreement
and this Agreement shall not have been terminated as provided in Article 10, the
parties to this Agreement shall cause a Certificate of Merger meeting the
requirements of Section 251 of the DGCL to be properly executed and filed in
accordance with such Section on the Closing Date. The Merger shall become
effective at the time of filing of the Certificate of Merger with the Secretary
of State of the State of Delaware in accordance with the DGCL or at such later
time which the parties to this Agreement shall have agreed upon and designated
in such filing as the effective time of the Merger (the "Effective Time"). From
and after the Effective Time, the Surviving Corporation shall possess all the
rights, privileges, powers and franchises and be subject to all of the
restrictions, disabilities and duties of the Company and Merger Sub, all as
provided under the DGCL.

    1.4.  ACTIONS BY THE COMPANY.  The Company hereby approves of and consents
to the Offer (as defined below), the Voting Agreements between Merger Sub and
certain of the Company's stockholders pursuant to which, among other things,
each such stockholder has agreed to vote all of his or its shares of the Common
Stock of the Company, par value $.01 per share (the "Common Stock"), in favor of
this Agreement and the Merger (the "Voting Agreements") and the Merger and
represents and warrants that the Board of Directors of the Company (the "Board
of Directors" or the "Board")

                                      A-1

at a meeting duly called and held has duly adopted, by unanimous vote (with one
director not present), resolutions (i) approving this Agreement, the Offer and
the Merger which approval satisfies in full the requirements of the DGCL and the
Certificate of Incorporation of the Company with respect to the requisite
approval of the board of directors, (ii) approving the Voting Agreements for the
purposes of Section 203 of the DGCL, and (iii) determining that the Merger is
advisable and that the terms of the Offer and Merger are fair to, and in the
best interests of, the Company's stockholders and recommending that the
Company's stockholders accept the Offer and approve the Merger and this
Agreement; PROVIDED, that such recommendations may be withdrawn, modified or
amended following receipt of an Acquisition Proposal (as defined in
Section 8.1) if the Company has complied with the provisions of Section 8.1. The
Company further represents and warrants that the Board of Directors has received
the written opinion of Hambrecht & Quist, LLC (the "Financial Advisor") that, as
of the date of such opinion and subject to the limitations set forth therein,
the proposed Merger Consideration (as defined below) or the Offer Consideration
(as defined below), as the case may be, to be received by the holders of shares
of Common Stock pursuant to the Merger and the Offer is fair to such holders
from a financial point of view (the "Fairness Opinion"). The Company hereby
consents to the inclusion in the Proxy Statement (as defined below) and the
Offer Documents (as defined below) of the recommendation of the Board of
Directors described in the first sentence of this Section 1.4. The Company
hereby represents and warrants that it has been authorized by the Financial
Advisor to permit, subject to prior review and consent by the Financial Advisor
(such consent not to be unreasonably withheld), references to the Fairness
Opinion in the Offer Documents and the Schedule 14D-9 (as defined below) and the
inclusion of the Fairness Opinion in the Proxy Statement.

Technologies, Inc.), until duly amended in accordance with applicable law.

    2.2.  BYLAWS.  The Bylaws of Merger Sub in effect immediately prior to the

                       EFFECT OF THE MERGER ON SECURITIES
                         OF MERGER SUB AND THE COMPANY

    4.1.  MERGER SUB STOCK.  At the Effective Time, each share of common stock,
$.01 par value per share, of Merger Sub outstanding immediately prior to the
Effective Time shall be converted into and exchanged for one validly issued,
fully paid and non-assessable share of common stock, $.01 par value per share,
of the Surviving Corporation.

                                      A-2

    4.2.  COMPANY SECURITIES.

    (a)  At the Effective Time, each share of Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of Common
Stock owned by Purchaser or Merger Sub or held by the Company, all of which
shall be cancelled, and other than shares of Dissenting Common Stock (as defined
below)) shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into the right to receive the Merger Consideration
from the Surviving Corporation. For purposes of this Agreement, the "Merger
Consideration" shall mean either (i) if the Company has consummated the
transactions contemplated by that certain Stock Purchase Agreement dated as of
August 23, 1999 among the Company, Bowthorpe plc, Bowthorpe B.V., Bowthorpe
International Inc., and Bowthorpe GmbH, as in effect on the date of this
Agreement or as subsequently amended with the prior consent of the Purchaser
(the "Thermalloy Agreement"), $25.50 per share of Common Stock or, (ii) if the
Thermalloy Agreement has been terminated prior to the consummation of the
transactions contemplated thereby, the Offer Consideration (as defined below),
in each case in cash, without interest.

    (b)  As a result of the Merger and without any action on the part of the
holder thereof, at the Effective Time all shares of Common Stock converted in
accordance with Section 4.2(a) shall cease to be outstanding and shall be
cancelled and retired and shall cease to exist, and each holder of shares of
Common Stock converted in accordance with Section 4.2(a) shall thereafter cease
to have any rights with respect to such shares of Common Stock, except the right
to receive, without interest, the Merger Consideration in accordance with
Section 4.3 upon the surrender of a certificate or certificates (a
"Certificate") representing such shares of Common Stock.

    (c)  Each share of Common Stock issued and held in the Company's treasury at
the Effective Time shall, by virtue of the Merger, cease to be outstanding and
shall be cancelled and retired without payment of any consideration therefor.

    (d)  (i) At or immediately prior to the Effective Time, each outstanding
employee stock option ("Options") to purchase shares of Common Stock granted
under any employee stock option or compensation plan or arrangement of the
Company (collectively, the "Stock Option Plans") shall be canceled, and each
holder of any such Option, whether or not then vested or exercisable, shall be
paid by the Company promptly after the Effective Time for each such Option an
amount determined by multiplying (x) the excess, if any, of the Merger
Consideration over the applicable per share exercise price of such Option by
(y) the number of shares of Common Stock such holder could have purchased
(assuming full vesting of all Options) had such holder exercised such Option in
full immediately prior to the Effective Time.

        (ii) Prior to the Effective Time, the Company shall use its reasonable
    best efforts (x) to obtain any consents from holders of Options to purchase
    shares of Common Stock granted under the Stock Option Plans and (y) make any
    amendments to the terms of the Stock Option Plans that, in the case of
    either clauses 4.2(d)(ii)(x) or 4.2(d)(ii)(y), are necessary to give effect
    to the transactions contemplated by Section 4.2(d)(i). Notwithstanding any
    other provision of this Section 4.2(d), payment may be withheld in respect
    of any Option until necessary consents are obtained.

        (iii) At the Effective Time each outstanding warrant or similar right
    (other than the Options) to purchase or otherwise acquire shares of Common
    Stock (a "Company Warrant") shall be converted into and be exchangeable for
    the right to receive, in lieu of the shares of Common Stock theretofore
    purchasable upon the exercise of the Company Warrant, an amount in cash
    equal to the product of (i) the excess, if any, of the Merger Consideration
    over the per share exercise price for one share of Common Stock subject to
    such Company Warrant multiplied by (ii) the number of shares of Common Stock
    subject to such Company Warrant. At the Effective Time, each Company Warrant
    with an exercise price equal to or greater than the Merger Consideration
    shall be

                                      A-3

    terminated without payment of any consideration. Prior to the Effective
    Time, the Company shall use its reasonable best efforts to obtain any
    necessary consents of each holder of a Company Warrant to the transactions
    contemplated by this Section 4.2(d)(iii). The Company shall provide to each
    holder of a Company Warrant any required notice under the Company Warrant.

    4.3.  EXCHANGE OF CERTIFICATES REPRESENTING COMMON STOCK.

    (a)  Prior to the Effective Time, Purchaser shall appoint a commercial bank
or trust company having net capital of not less than $20 billion, or such other
party reasonably satisfactory to the Company, to act as paying agent hereunder
for payment of the Merger Consideration upon surrender of Certificates (the
"Paying Agent"). Purchaser shall, or shall cause the Surviving Corporation to,
provide the Paying Agent with cash in amounts necessary to pay for all the
shares of Common Stock pursuant to Section 4.2(a) as and when such amounts are
needed by the Paying Agent. Such amounts shall hereinafter be referred to as the
"Exchange Fund." The Exchange Fund shall not be used for any other purpose than
as specified in this Section 4.3(a).

    (b)  Promptly after the Effective Time, Purchaser shall cause the Paying
Agent to mail to each holder of record of shares of Common Stock (other than
holders of shares of Dissenting Common Stock) (i) a letter of transmittal which
shall specify that delivery shall be effected, and risk of loss and title to
such Certificates shall pass, only upon delivery of the Certificates to the
Paying Agent and which letter shall be in such form and have such other
provisions as Purchaser may reasonably specify and (ii) instructions for
effecting the surrender of such Certificates in exchange for the Merger
Consideration. Upon surrender of a Certificate to the Paying Agent together with
such letter of transmittal, duly executed and completed in accordance with the
instructions thereto, and such other documents as may reasonably be required by
the Paying Agent, the holder of such Certificate shall promptly receive in
exchange therefor the amount of cash into which shares of Common Stock
previously represented by such Certificate shall have been converted pursuant to
Section 4.2, and the shares represented by the Certificate so surrendered shall
forthwith be cancelled. No interest will be paid or will accrue on the cash
payable upon surrender of any Certificate. In the event of a transfer of
ownership of Common Stock which is not registered in the transfer records of the
Company, payment may be made with respect to such Common Stock to such a
transferee if the Certificate representing such shares of Common Stock is
presented to the Paying Agent, accompanied by all documents required to evidence
and effect such transfer and to evidence that any applicable stock transfer
taxes have been paid.

    (c)  At or after the Effective Time, there shall be no transfers on the
stock transfer books of the Company of the shares of Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation, they shall be
cancelled and exchanged as provided in this Article 4.

    (d)  Any portion of the Exchange Fund (including the proceeds of any
interest and other income received by the Paying Agent in respect of all such
funds) that remains unclaimed by the former stockholders of the Company nine
months after the Effective Time shall be delivered to the Surviving Corporation
(subject to abandoned property, escheat or similar laws). Any former
stockholders of the Company who have not previously complied with this
Article 4 shall thereafter look only to the Surviving Corporation (subject to
abandoned property, escheat or similar laws) for payment of any Merger
Consideration that may be payable in respect of each share of Common Stock such
stockholder holds as determined pursuant to this Agreement, without any interest
thereon. Any amounts remaining unclaimed by holders of Common Stock two years
after the Effective Time (or such earlier date immediately prior to such time as
such amounts would otherwise escheat to or become property of any governmental
entity) shall, to the extent permitted by applicable law, become the property of
the Surviving Corporation free and clear of any claims or interest of any Person
(as defined in Section 11.8) previously entitled thereto.

                                      A-4

    (e)  None of Purchaser, the Company, the Surviving Corporation, the Paying
Agent or any other Person shall be liable to any former holder of shares of
Common Stock for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

    (f)  If any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Surviving Corporation, the
posting by such Person of a bond in such reasonable amount as the Surviving
Corporation may direct as indemnity against any claim that may be made against
it with respect to such Certificate, the Paying Agent will issue in exchange for
such lost, stolen or destroyed Certificate the Merger Consideration payable in
respect thereof pursuant to this Agreement.

    4.4.  ADJUSTMENT OF MERGER CONSIDERATION.  If, subsequent to the date of
this Agreement but prior to the Effective Time, the outstanding shares of Common
Stock shall have been changed into a different number of shares or a different
class as a result of a stock split, reverse stock split, stock dividend,
subdivision, reclassification, split, combination, exchange, recapitalization or
other similar transaction, the Merger Consideration shall be appropriately
adjusted.

    4.5.  DISSENTING COMPANY STOCKHOLDERS.  Notwithstanding any provision of
this Agreement to the contrary, if required by the DGCL but only to the extent
required thereby, shares of Common Stock which are issued and outstanding
immediately prior to the Effective Time and which are held by holders of such
shares of Common Stock who have properly exercised appraisal rights with respect
thereto in accordance with Section 262 of the DGCL (the "Dissenting Common
Stock") will not be exchangeable for the right to receive the Merger
Consideration, and holders of such shares of Dissenting Common Stock will be
entitled to receive payment of the appraised value of such shares of Common
Stock in accordance with the provisions of such Section 262 unless and until
such holders fail to perfect or effectively withdraw or lose their rights to
appraisal and payment under the DGCL. If, after the Effective Time, any such
holder fails to perfect or effectively withdraws or loses such right, such
shares of Common Stock will thereupon be treated as if they had been converted
into and had become exchangeable for, at the Effective Time, the right to
receive the Merger Consideration, without any interest thereon. The Company will
give Purchaser prompt notice of any demands received by the Company for
appraisals of shares of Common Stock. The Company shall not, except with the
prior written consent of Purchaser, make any payment with respect to any demands
for appraisal or offer to settle or settle any such demands unless such payment
is ordered by a court of competent jurisdiction which order is final and
non-appealable.

                                   ARTICLE 5
                                   THE OFFER

    5.1  THE OFFER.  Subject to the provisions of this Agreement and this
Agreement not having been terminated, if the Thermalloy Agreement is terminated
prior to the Company's consummation of the transactions contemplated thereby,
then Merger Sub may, upon written notice to the Company (the "Purchaser
Notice"), and shall if the Company so requests in writing (the "Company
Request") (and the Purchaser shall cause Merger Sub to), commence, within the
meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended, and
the rules and regulations promulgated thereunder (the "Exchange Act"), as
promptly as practicable but in no event later than five business days after
giving the Purchaser Notice or receiving the Company Request, an offer to
purchase all of the outstanding shares of Common Stock at a price (the "Offer
Consideration") of $24.50 per share of Common Stock net to the seller in cash
(the "Offer"). Subject to the conditions set forth in Exhibit A, Merger Sub
shall not withdraw the Offer and shall purchase all Common Stock duly tendered
and not withdrawn. The obligation of Merger Sub to, and of Purchaser to cause
Merger Sub to, accept for payment, and pay for, any shares of Common Stock
tendered pursuant to the Offer shall be subject only to the condition that there
shall have been validly tendered in accordance with the terms of the Offer prior
to the expiration date of the Offer and not withdrawn a number of shares of
Common

                                      A-5

Stock which, together with the shares then owned by Purchaser or Merger Sub,
represents at least a majority of the shares of Common Stock outstanding on a
fully diluted basis (the "Minimum Condition"), and to the other conditions set
forth in Exhibit A to this Agreement and subject to the terms and conditions of
this Agreement. For purposes of this Agreement, "on a fully diluted basis"
means, as of any date, the number of shares of Common Stock outstanding,
together with the number of shares of Common Stock the Company is then required
to issue pursuant to obligations outstanding at that date under the Stock Option
Plans or otherwise (assuming all Options and other rights to acquire Common
Stock are fully vested and exercisable and all Common Stock issuable at any time
thereunder has been issued). Subject to the provisions of the Offer, the Offer
shall expire 20 business days (as defined in Rule 14d-1(c)(6) promulgated under
the Exchange Act) after the date of its commencement, unless this Agreement is
terminated in accordance with Article 10, in which case the Offer (whether or
not previously extended in accordance with the terms of this Agreement) shall
expire on such date of termination. Merger Sub expressly reserves the right to
extend the Offer and to waive the Minimum Condition or any of the other
conditions to the Offer and to make any change in the terms or conditions of the
Offer; PROVIDED that the Merger Sub shall not waive the Minimum Condition
without the consent of the Company; and PROVIDED further that no change may be
made which changes the form of consideration to be paid or decreases the price
per share of Common Stock or the number of shares sought in the Offer or which,
except as provided in the next sentence, extends the Offer or which modifies or
imposes conditions to the Offer in addition to those set forth in Exhibit A or
which otherwise materially and adversely affects the Company or the holders of
the Common Stock. Notwithstanding the foregoing, Merger Sub may, without the
consent of the Company, (i) extend the Offer on one or more occasions for not
more than 10 business days for each such extension beyond the scheduled
expiration date (the initial scheduled expiration date being 20 business days
following commencement of the Offer), if at the scheduled expiration date of the
Offer any of the conditions to Merger Sub's obligation to accept for payment,
and pay for, shares of Company Common Stock shall not be satisfied or waived,
until such time as such conditions are satisfied or waived, (ii) extend the
Offer for any period required by any rule, regulation, interpretation or
position of the Securities and Exchange Commission (the "SEC") or the staff
thereof applicable to the Offer and (iii) extend the Offer for an aggregate
period of not more than 15 business days beyond the latest expiration date that
would otherwise be permitted under clause (i) or (ii) of this sentence if there
shall not have been tendered sufficient shares of Common Stock so that the
Merger could be effected as provided in Section 5.5. Subject to the terms and
conditions of the Offer and this Agreement, Merger Sub shall, and Purchaser
shall cause Merger Sub to, accept for payment, and pay for, all shares of Common
Stock validly tendered and not withdrawn pursuant to the Offer that Merger Sub
becomes obligated to accept for payment, and pay for, pursuant to the Offer as
soon as practicable after the expiration of the Offer.

    5.2.  ACTIONS BY PURCHASER AND MERGER SUB.  As soon as reasonably
practicable following receipt of the Company Request or giving of the Purchaser
Notice, but in no event later than five business days from such date, Purchaser
and Merger Sub shall file with the SEC a Tender Offer Statement on
Schedule 14D-1 with respect to the Offer, which shall contain an offer to
purchase and a related letter of transmittal and any other ancillary documents
pursuant to which the Offer shall be made (such Schedule 14D-1 and the documents
therein pursuant to which the Offer will be made, together with any supplements
or amendments thereto, the "Offer Documents"). The Company and its counsel shall
be given an opportunity to review and comment on the Schedule 14D-1 and each
amendment and supplement thereto, in each case prior to the filing thereof with
the SEC. The Offer Documents shall comply as to form in all material respects
with the requirements of the Exchange Act, and on the date filed with the SEC
and on the date first published, sent or given to the Company's stockholders,
the Offer Documents shall not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading, except that no representation is made by
Purchaser or Merger Sub with respect to information supplied by or on

                                      A-6

behalf of the Company for inclusion in the Offer Documents. Each of Purchaser,
Merger Sub and the Company agrees promptly to correct any information provided
by it for use in the Offer Documents if and to the extent that such information
shall have become false or misleading in any material respect, and each of
Purchaser, Merger Sub and the Company further agrees to take all steps necessary
to cause the Offer Documents as so corrected to be filed with the SEC and to be
disseminated to holders of shares of Common Stock, in each case as and to the
extent required by applicable federal securities laws. Purchaser and Merger Sub
agree to provide the Company and its counsel in writing with any comments
Purchaser, Merger Sub or their counsel may receive from the SEC or its staff
with respect to the Offer Documents promptly after receipt of such comments and
with copies of any written responses and telephonic notification of any verbal
responses by Purchaser, Merger Sub or their counsel.

    Purchaser shall provide or cause to be provided to Merger Sub on a timely
basis the funds necessary to accept for payment, and pay for, any shares of
Common Stock that Merger Sub becomes obligated to accept for payment, and pay
for, pursuant to the Offer.

    None of the information supplied by Purchaser or Merger Sub for inclusion or
incorporation by reference in the Schedule 14D-9 (as defined below) or the
Information Statement (as defined below) will, at the respective times such
documents are filed with the SEC or first published, sent or given to the
Company stockholders, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading. If at any time prior to the Effective Time either
Purchaser or Merger Sub shall obtain knowledge of any facts with respect to
itself, any of its officers and directors or any of its Subsidiaries that would
require the supplement or amendment to any of the foregoing documents in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, or to comply with applicable Laws (as defined
below), such amendment or supplement shall be promptly filed with the SEC and,
as required by Law, disseminated to the stockholders of the Company, and in the
event the Company shall advise Purchaser or Merger Sub as to its obtaining
knowledge of any facts that would make it necessary to supplement or amend any
of the foregoing documents, Purchaser or Merger Sub shall promptly amend or
supplement such document as required and distribute the same to the stockholders
of the Company.

    5.3.  COMPANY ACTIONS.

    (a)  On the date the Offer Documents are filed with the SEC, the Company
shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended from
time to time, the "Schedule 14D-9") containing the recommendations described in
the first sentence of Section 1.4 above and shall mail the Schedule 14D-9 to the
stockholders of the Company. The Company shall cooperate with Purchaser in
mailing or otherwise disseminating the Schedule 14D-9 with the appropriate Offer
Documents to the Company's stockholders. Purchaser and its counsel shall be
given an opportunity to review and comment upon the Schedule 14D-9 and each
amendment and supplement thereto prior to the filing thereof with the SEC. The
Company covenants that none of the Schedule 14D-9, the information statement, if
any, filed by the Company in connection with the Offer pursuant to Rule 14f-1
under the Exchange Act (the "Information Statement"), any schedule required to
be filed by the Company with the SEC in connection with the Offer or any
amendment or supplement thereto, at the respective times such documents are
filed with the SEC or first published, sent or given to the Company's
stockholders, will contain any untrue statement of a material fact or will omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in the light of the circumstances under which
they are made, not misleading except that no representation is made by the
Company with respect to information supplied by Purchaser or Merger Sub for
inclusion in the Schedule 14D-9 or Information Statement or any schedule,
amendment or supplement. The Company covenants that none of the information
supplied or to be supplied by the Company for inclusion or incorporation by
reference in the Offer Documents will, at the date of filing with the SEC,
contain any untrue statement

                                      A-7

of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. Each of the Company,
Purchaser and Merger Sub agrees promptly to correct any information provided by
it for use in the Schedule 14D-9 if and to the extent that such information
shall have become false or misleading in any material respect, and the Company
further agrees to take all steps necessary to cause the Schedule 14D-9 as so
corrected to be filed with the SEC and to be disseminated to the holders of
shares of Common Stock, in each case as and to the extent required by applicable
federal securities laws. The Company agrees to provide Purchaser and Merger Sub
and their counsel in writing with any comments the Company or its counsel may
receive from the SEC or its staff with respect to the Schedule 14D-9 promptly
after the receipt of such comments and with copies of any written responses and
telephonic notification of any verbal responses by the Company or its counsel.

    (b)  In connection with the Offer, the Company shall cause its transfer
agent to furnish Merger Sub with mailing labels containing the names and
addresses of the record holders of Common Stock as of a recent date and of those
Persons becoming record holders subsequent to such date, together with copies of
all lists of stockholders, security position listings and computer files and all
other information in the Company's possession or control regarding the
beneficial owners of Common Stock, and shall furnish to Merger Sub such
information and assistance (including updated lists of stockholders, security
position listings and computer files) as Merger Sub may reasonably request in
communicating the Offer to the Company's stockholders. Subject to the
requirements of law, and except for such steps as are necessary to disseminate
the Offer Documents and any other documents necessary to consummate the Offer
and the Merger, Purchaser and Merger Sub and each of their affiliates and
associates shall hold in confidence the information contained in any of such
labels, lists and files, shall use such information only in connection with the
Offer and the Merger, and, if this Agreement is terminated, shall promptly
deliver to the Company all copies of such information then in their possession.

    (c)  Subject to the terms and conditions of this Agreement, if there shall
occur a change in law or in a binding judicial interpretation of existing law
which would, in the absence of action by the Company or the Board, prevent the
Merger Sub, were it to acquire a specified percentage of the shares of Common
Stock then outstanding, from approving and adopting this Agreement by its
affirmative vote as the holder of a majority of the shares of Common Stock and
without the affirmative vote of any other stockholder, the Company will use its
reasonable best efforts to promptly take or cause such action to be taken unless
the Board of Directors of the Company in good faith determines, after
consultation with outside counsel, that taking or causing such action to be
taken would violate the fiduciary duties of the Board of Directors to the
stockholders of the Company under applicable law.

    5.4.  DIRECTORS

    (a)  Promptly upon the purchase of shares of Common Stock pursuant to the
Offer, Purchaser shall be entitled to designate such number of directors,
rounded up to the next whole number, as will give Purchaser representation on
the Board of Directors equal to the product of (i) the number of directors on
the Board of Directors and (ii) the percentage that the number of shares of
Common Stock purchased by Merger Sub or Purchaser or any affiliate bears to the
number of shares of Common Stock outstanding (the "Percentage"), and the Company
shall, upon request by Purchaser, promptly increase the size of the Board of
Directors and/or exercise its reasonable best efforts to secure the resignations
of such number of directors as is necessary to enable Purchaser's designees to
be elected to the Board of Directors and shall take all actions available to the
Company to cause Purchaser's designees to be so elected. At the request of
Purchaser, the Company will use its best efforts to cause such individuals
designated by Purchaser to constitute the same Percentage of (i) each committee
of the Board, (ii) the board of directors of each of the Company's Subsidiaries
and (iii) the committees of each such board of directors. The Company's
obligations to appoint designees to the Board of Directors shall be subject to
Section 14(f) of the Exchange Act. The Company shall take, at its expense, all
action necessary to effect any such election, and shall include in the
Schedule 14D-9 the

                                      A-8

information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder. Purchaser will supply to Company in writing and be
solely responsible for any information with respect to itself and its nominees,
directors and affiliates required by Section 14(f) and Rule 14f-1.
Notwithstanding the foregoing, the parties to this Agreement shall use their
respective reasonable best efforts to ensure that at least two of the members of
the Board of Directors shall at all times prior to the Effective Time be
Continuing Directors (as defined below); PROVIDED that, in such event, if the
number of Continuing Directors shall be reduced below two for any reason
whatsoever, the remaining Continuing Director shall be entitled to designate an
individual to fill such vacancy who shall be deemed to be a Continuing Director
for purposes of this Agreement or, if no Continuing Director then remains, the
other directors shall designate two individuals to fill such vacancies who shall
not be officers of the Company or stockholders, directors, officers, employees,
affiliates or associates of Merger Sub or Purchaser or any of their affiliates
or associates and such persons shall be deemed to be Continuing Directors for
purposes of this Agreement.

    (b)  Following the election or appointment of Purchaser's designees pursuant
to this Section 5.4 and prior to the Effective Time, the approval of a majority
of the directors of the Company then in office who are not designated by
Purchaser (the "Continuing Directors") shall be required to authorize (and such
authorization shall constitute the authorization of the Board of Directors and
no other action on the part of the Company, including any action by any other
director of the Company, shall be required to authorize) any termination of this
Agreement by the Company, any amendment of this Agreement requiring action by
the Board of Directors, any extension of time for the performance of any of the
obligations or other acts of Purchaser or Merger Sub, any exercise of any of the
Company's rights, benefits or remedies hereunder, and any waiver of compliance
with any of the agreements or conditions contained in this Agreement for the
benefit of the Company.

    5.5.  MERGER WITHOUT MEETING OF STOCKHOLDERS.  Notwithstanding the
foregoing, if Merger Sub, or any other direct or indirect Subsidiary of
Purchaser, shall acquire at least 90 percent of the outstanding shares of Common
Stock, the parties to this Agreement shall take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after the
expiration of the Offer without a meeting of stockholders of the Company, in
accordance with Section 253 of the DGCL.

                                   ARTICLE 6
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

business as a foreign corporation and is in good standing under the laws of any
other state of the United States in which the character of the properties owned
or leased by it or in which the transaction of its business makes such

good standing, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Effect (as defined in Section 11.8). Each of
the Company and its Significant Subsidiaries (as defined in Section 11.8) has
all requisite corporate power and authority to own, operate and lease its
properties and carry on its business as now conducted, except where the failure

previously delivered to Purchaser true and correct copies of the Company's
Certificate of Incorporation and Bylaws as currently in effect.

                                      A-9

    6.2.  AUTHORIZATION, VALIDITY AND EFFECT OF AGREEMENTS.  The Company has the

and all agreements and documents contemplated hereby or executed in connection
herewith (the "Ancillary Documents") and subject to obtaining any necessary

Agreement and the Ancillary Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby have been duly and
validly authorized by the Board of Directors, and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement and the

laws relating to creditors' rights and general principles of equity.

and decrees ("Laws") of any foreign, federal, state or local judicial,
legislative, executive, administrative or regulatory body or authority or any

of 25,000,000 shares of Common Stock, $.01 par value, and 4,000,000 shares of
preferred stock, $.01 par value ("Preferred Stock"). As of August 16, 1999,

voting securities of the Company, and no existing options, warrants, calls,
subscriptions, convertible securities, or other rights, agreements or
commitments which obligate the Company or any of its Subsidiaries to issue,

owns, directly or indirectly through a Subsidiary, all of the outstanding shares
of capital stock (or other ownership interests having by their terms ordinary
voting power to elect directors or others performing similar functions with
respect to such Subsidiary) of each of the Company's Subsidiaries, and
(ii) each of the outstanding shares of capital stock of each of the Company's
Subsidiaries is duly authorized, validly issued, fully paid and nonassessable,
and is owned, directly or indirectly, by the Company free and clear of all
liens, pledges, security interests, claims or other encumbrances

or other entity.

    6.6.  NO VIOLATION.  Except as set forth in Schedule 6.6, neither the
execution and delivery by the Company of this Agreement or any of the Ancillary
Documents nor the consummation by the Company of the transactions contemplated
hereby or thereby will: (i) violate, conflict with or result in a breach of any

obligation to which the Company or any of its Subsidiaries is a party, or by
which the Company or any of its Subsidiaries or any of their respective
properties is bound (each, a "Contract" and collectively, "Contracts"), except
for any of the foregoing matters which individually or in the aggregate would
not reasonably be expected to have a Material Adverse Effect; (iii) other than

the Securities Act of 1933, as amended (the "Securities Act"), require any
consent, approval or authorization of, or declaration, filing or registration
with, any Governmental Entity, the lack of which individually or in the
aggregate would reasonably be expected to have a Material Adverse Effect or by
Law prevent the consummation of the transactions contemplated hereby; and
(iv) violate any Laws applicable to the Company, any of its Subsidiaries or any
of their respective assets, except for violations which individually or in the
aggregate would not reasonably be expected to have a Material Adverse Effect or
materially adversely affect the ability of the Company to consummate the
transactions contemplated hereby.

    6.7.  COMPANY REPORTS.  The Company has delivered to Purchaser each
registration statement, report, proxy statement or information statement (as
defined under the Exchange Act) prepared by it since January 1, 1997, each in

material respects with the

                                      A-11

applicable requirements of the Securities Act, the Exchange Act, and the rules
and regulations thereunder and (ii) the Company Reports did not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements made therein, in the light
of the circumstances under which they were made, not misleading.

    6.8.  FINANCIAL STATEMENTS.  The audited consolidated financial statements
and unaudited consolidated interim financial statements of the Company included
in the Company's Annual Report on Form 10-K for the year ended December 31, 1998
and its Quarterly Report on Form 10-Q for the six month period ended July 3,

interim financial statements), the consolidated financial position of the
Company and its consolidated Subsidiaries as of the dates thereof and their

set forth in the Company Reports, no Governmental Entity has indicated in
writing an intention to conduct any audit, investigation or other review with
respect to the Company or any of its Subsidiaries which investigation or review,
if adversely determined, individually or in the aggregate would reasonably be
expected to have a Material Adverse Effect.

    6.10.  ABSENCE OF CERTAIN CHANGES.  Except as set forth in Schedule 6.10 or

Subsidiaries have conducted their business only in the ordinary course of such

employees; or

    (l)  any cancellation of any licenses, sublicenses, franchises, permits or

arrangements intends to cancel or not renew such arrangements beyond its
expiration date as in effect on the date hereof, which cancellation or
notification, individually or in the aggregate, has had or reasonably would be
expected to have a Material Adverse Effect.

    6.11.  TAXES.

    (a)  Except as set forth in Schedule 6.11, and except where the failure to
file such Return has not had and would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect, all tax returns,
statements, reports and forms (including estimated tax returns and reports and
information returns and reports) required to be filed with any taxing authority
with respect to any tax period (or portion thereof) ending on or before the
Effective Time (a "Pre-Closing Tax Period") by or on behalf of the Company or
any Subsidiary of the Company (collectively, the "Returns"), were filed when due
(including any applicable extension periods) in accordance with all applicable
laws.

                                      A-13

    (b)  Except as set forth in Schedule 6.11, the Company and its Subsidiaries
have timely paid, or withheld and remitted to the appropriate taxing authority,
all taxes required to be paid, withheld or remitted or shown as due and payable
on the Returns that have been filed, except where the failure to so pay or
withhold and remit has not had and would not be reasonably expected to have,
individually or in the aggregate, a Material Adverse Effect.

    (c)  The charges, accruals and reserves for taxes with respect to the
Company and any Subsidiary for any Pre-Closing Tax Period (including any
Pre-Closing Tax Period for which no Return has yet been filed) reflected on the
books of the Company and its Subsidiaries (excluding any provision for deferred
income taxes) are adequate to cover such taxes.

    (d)  Except as set forth in Schedule 6.11, there is no material claim
(including under any indemnification or tax-sharing agreement), audit, action,
suit, proceeding, or investigation now pending or, to the Company's knowledge,
threatened against or in respect of any tax or "tax asset" of the Company or any
Subsidiary. For purposes of this Section 6.11, the term "tax asset" shall
include any net operating loss, net capital loss, investment tax credit, foreign
tax credit, charitable deduction or any other credit or tax attribute that could
reduce taxes.

    (e)  There are no material Encumbrances for taxes upon the assets of the
Company or its Subsidiaries except for Encumbrances for current taxes not yet
due, or taxes being contested in good faith by appropriate proceedings for which
adequate reserves have been established on the Company's books.

    (f)  Neither the Company nor any of its Subsidiaries has been a United
States real property holding corporation within the meaning of
Section 897(c)(2) of the Internal Revenue Code of 1986, as amended (the "Code")
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.

    6.12.  EMPLOYEE BENEFIT PLANS.

    (a)  The Company has provided Purchaser with a list identifying each
"employee benefit plan", as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), which (i) is subject to any
provision of ERISA and (ii) is maintained, administered or contributed to by the
Company or any Subsidiary or affiliate (as defined below) and covers any
employee or former employee of the Company or any Subsidiary or affiliate to
which the Company or any Subsidiary or affiliate has any material liability.
Copies of such plans (and, if applicable, related trust agreements) and all
amendments thereto have been furnished to Purchaser together with (A) the most
recent annual report (Form 5500 including, if applicable, Schedule B thereto)
prepared in connection with any such plan and (B) the most recent actuarial
valuation report prepared in connection with any such plan. Such plans are
referred to collectively in this Agreement as the "Employee Plans". For purposes
of this Section, "affiliate" of any Person means any other Person which,
together with such Person, would be treated as a single employer under
Section 414 of the Code. The only Employee Plans which individually or
collectively would constitute an "employee pension benefit plan" as defined in
Section 3(2) of ERISA (the "Pension Plans") are identified as such in the list
referred to above. The Company has provided Purchaser with complete age, salary,
service and related data as of a recent date for employees and former employees
of the Company and any affiliate covered under the Pension Plans.

    (b)  Except as otherwise indicated on Schedule 6.12(b), no Employee Plan
(i) constitutes a "multiemployer plan", as defined in Section 3(37) of ERISA;
(ii) is maintained in connection with any trust described in Section 501(c)(9)
of the Code; or (iii) is subject to Title IV of ERISA. The Company knows of no
"reportable event", within the meaning of Section 4043 of ERISA, for which
notice is not waived, and no event described in Section 4041, 4042, 4062 or 4063
of ERISA which has occurred in connection with any Employee Plan. Neither the
Company nor any of its affiliates has incurred any unsatisfied liability under
Title IV of ERISA arising in connection with the termination of, or complete or
partial withdrawal from, any plan covered or previously covered by Title IV of
ERISA. Nothing

                                      A-14

done or omitted to be done and no transaction or holding of any asset under or
in connection with any Employee Plan has caused the Company or any Subsidiary,
or any officer or director of the Company or any Subsidiary, to be subject to
any liability under Title I of ERISA or liable for any tax pursuant to
Section 4975 of the Code.

    (c)  Each Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from tax pursuant to Section 501(a) of the Code. The Company has
furnished to Purchaser copies of the most recent Internal Revenue Service
determination letters with respect to each such Employee Plan. Each Employee
Plan has been maintained in substantial compliance with its terms and with the
applicable requirements prescribed by any and all statutes, orders, rules and
regulations, including but not limited to ERISA and the Code.

    (d)  Except as otherwise indicated on Schedule 6.12(d), there is no
contract, agreement, plan or arrangement covering any employee or former
employee of the Company or any affiliate that, individually or collectively,
could give rise to the payment of any amount that would not be deductible
pursuant to the terms of Sections 162(a)(1) or 280G of the Code.

    (e)  The Company has provided Purchaser with a list of each employment,
severance or other similar contract, arrangement or policy and each plan or
arrangement (written or oral) providing for insurance coverage (including any
self-insured arrangements), workers' compensation, disability benefits,
supplemental unemployment benefits, vacation benefits, retirement benefits or
for deferred compensation, profit-sharing, bonuses, stock options, stock
appreciation or other forms of incentive compensation or post-retirement
insurance, compensation or benefits which (i) is not an Employee Plan, (ii) is
entered into, maintained or contributed to, as the case may be, by the Company
or any of its Subsidiaries or affiliates and (iii) covers any executive officer
or director or any employee or former employee of the Company or any of its
Subsidiaries or affiliates earning a salary in excess of $150,000 per annum.
Such contracts, plans and arrangements as are described above, copies or
descriptions of all of which have been furnished previously to Purchaser, are
referred to collectively in this Agreement as the "Benefit Arrangements." Each
Benefit Arrangement has been maintained in substantial compliance with its terms
and with the requirements prescribed by any and all statutes, orders, rules and
regulations that are applicable to such Benefit Arrangement.

    (f)  The Company does not provide post-employment health or medical benefits
for former employees of the Company and its Subsidiaries or affiliates except as
required to avoid imposition of tax under Section 4980B of the Code. No
condition exists that would prevent the Company or any Subsidiary from amending
or terminating any Employee Plan or Benefit Arrangement providing health or
medical benefits in respect of any active employee of the Company or any
Subsidiary other than limitations imposed under the terms of a collective
bargaining agreement.

    (g)  Except as disclosed in writing to Purchaser prior to the date hereof or
as required by applicable law, there has been no amendment to, written
interpretation or announcement (whether or not written) by the Company or any of
its Subsidiaries or affiliates relating to, or change in employee participation
or coverage under, any Employee Plan or Benefit Arrangement which would increase
materially the expense of maintaining such Employee Plan or Benefit Arrangement
above the level of the expense incurred in respect thereof for the fiscal year
ended December 31, 1998.

    (h)  Except as set forth in Schedule 6.12(h), neither the Company nor any
Subsidiary is a party to or subject to any union contract or any employment
contract or arrangement providing for annual future compensation of $150,000 or
more with any officer, consultant, director or employee.

    (i)  Schedule 6.12(i) identifies each International Plan (as defined below).
The Company has furnished to Purchaser copies of each International Plan. Each
International Plan has been maintained in substantial compliance with its terms
and with the requirements prescribed by any and all applicable statutes, orders,
rules and regulations (including any special provisions relating to qualified
plans where

                                      A-15

such Plan was intended to so qualify) and has been maintained in good standing
with applicable regulatory authorities. Except as required by applicable law,
there has been no amendment to, written interpretation of or announcement
(whether or not written) by the Company or any Subsidiary relating to, or change
in employee participation or coverage under, any International Plan that would
increase materially the expense of maintaining such International Plan above the
level of expense incurred in respect thereof for the most recent fiscal year
ended prior to the date hereof.

        "International Plan" means any employment, severance or similar contract
or arrangement (whether or not written) or any plan, policy, fund, program or
arrangement or contract providing for severance, insurance coverage (including
any self-insured arrangements), workers' compensation, disability benefits,
supplemental unemployment benefits, vacation benefits, pension or retirement
benefits or for deferred compensation, profit-sharing, bonuses, stock options,
stock appreciation rights or other forms of incentive compensation or
post-retirement insurance, compensation or benefits that (i) is not an Employee
Plan or a Benefit Arrangement, (ii) is entered into, maintained, administered or
contributed to by the Company or any Subsidiary and (iii) covers any executive
officer or director or any employee or former employee of the Company or any
Subsidiary earning a salary in excess of $150,000 per annum.

    6.13.  LABOR AND EMPLOYMENT MATTERS.  Except as set forth in Schedule 6.13,
neither the Company nor any of its Subsidiaries is a party to, or bound by, any
collective bargaining agreement or other Contracts or understanding with a labor
union or labor organization. Except for such matters which, individually or in
the aggregate, would not reasonably be expected to have a Material Adverse
Effect, there is no (i) unfair labor practice, labor dispute (other than routine
individual grievances) or labor arbitration proceeding pending or, to the
knowledge of the Company, threatened against the Company or its Subsidiaries
relating to their business, (ii) to the knowledge of the Company, activity or
proceeding by a labor union or representative thereof to organize any employees
of the Company or any of its Subsidiaries, or (iii) lockouts, strikes,
slowdowns, work stoppages or, to the knowledge of the Company, threats thereof
by or with respect to such employees.

    6.14.  BROKERS.  Except for the Financial Advisor and the Company's
financial advisor in respect of the transactions contemplated by the Thermalloy
Agreement, no broker, finder or financial advisor is entitled to any brokerage,
finder's or other fee or commission in connection with the transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
the Company. The Company's fee arrangements with the Financial Advisor have been
disclosed to Purchaser.

    6.15.  LICENSES AND PERMITS.  Except as set forth in Schedule 6.15, the
Company and its Subsidiaries have all necessary licenses, franchises, permits,
certificates, approvals or other similar authorizations (the "Permits") required
to lawfully conduct their respective businesses as presently conducted, except
for those Permits the lack of which individually or in the aggregate would not
reasonably be expected to have a Material Adverse Effect, and (a) no Permit is
subject to revocation or forfeiture by virtue of any existing circumstances,
(b) there is no Litigation pending or, to the knowledge of the Company,
threatened to modify or revoke any Permit, and (c) no Permit is subject to any
outstanding order, decree, judgment, stipulation, or, to the knowledge of the
Company, investigation that would reasonably be likely to affect such Permit,
where the effect of the foregoing individually or in the aggregate would
reasonably be expected to have a Material Adverse Effect.

    6.16.  INTELLECTUAL PROPERTY.

    (a)  Schedule 6.16 contains a complete and accurate list of all
(i) patented or registered Intellectual Property (as defined in Section 11.8)
owned or filed by the Company or any Subsidiary, (ii) pending patent
applications and applications for registration of other Intellectual Property
filed by or on behalf of the Company or any Subsidiary, (iii) material
unregistered trade names, corporate names, or Internet domain names owned or
used by the Company or any Subsidiary, (iv) material

                                      A-16

unregistered trademarks, service marks, copyrights and mask works owned or used
by the Company or any Subsidiary, (v) all computer software owned and/or used by
the Company or any of its Subsidiaries (other than mass-marketed software with a
license fee of less than $50,000) that is material to the Business, and
(vi) all material licenses or similar agreements or arrangements pertaining to
Intellectual Property to which the Company or its Subsidiaries is a party,
either as licensee or licensor.

    (b)  Except as set forth on Schedule 6.16, (i) the Company or one of its
Subsidiaries owns or possesses adequate licenses or other rights to use all
Intellectual Property necessary for the operation of the businesses of the
Company and its Subsidiaries as presently conducted, except where the failure to
own or possess would not reasonably be expected to have a Material Adverse
Effect and free and clear of all Encumbrances or restrictions other than
Permitted Liens (as defined in Section 6.18) and, in the case of licensed
Intellectual Property, as set forth in the license therefor; (ii) no claim by
any other Person contesting the validity, enforceability, use or ownership of
any of the Intellectual Property owned or used by the Company or any of its
Subsidiaries (the "Company Intellectual Property") has been made, is currently
outstanding or, to the knowledge of the Company, is threatened (including,
without limitation, any demand or request that the Company or its Subsidiaries
license any rights from a third Person); (iii) neither the Company nor its
Subsidiaries have received any notices of, nor are aware of any facts which
indicate a reasonable likelihood of, any infringement or misappropriation by any
third Person with respect to the Company Intellectual Property that would
reasonably be expected to have a Material Adverse Effect; (iv) to the knowledge
of the Company, neither the Company nor its Subsidiaries have infringed or
misappropriated any Intellectual Property or other rights of any third Persons
in a manner that would reasonably be expected to have a Material Adverse Effect,
and neither the Company nor its Subsidiaries is aware of any infringement or
misappropriation which will occur as a result of the continued operation of the
business of the Company or its Subsidiaries as currently conducted and which
would reasonably be expected to have a Material Adverse Effect; (v) to the
Company's knowledge, no loss or expiration of any of the material Company
Intellectual Property is threatened, pending or reasonably foreseeable;
(vi) the transactions contemplated by this Agreement will have no Material
Adverse Effect on the right, title and interest in and to the Company
Intellectual Property; and (vii) the Company and its Subsidiaries have taken all
actions to maintain and protect the Company Intellectual Property which they
have determined to be commercially reasonable.

    (c)  The Company and each of its Subsidiaries have conducted an inventory
and assessment of the hardware, software and embedded microcontrollers in
noncomputer equipment (collectively, the "Computer Systems") used by and
material to the Company and its Subsidiaries in its business, in order to
determine which parts of the Computer Systems are not Year 2000 Compliant (as
defined below) and to estimate the cost of rendering such Computer Systems Year
2000 Compliant prior to January 1, 2000 or such earlier date on which the
Computer Systems may shut down or may produce incorrect calculations or
otherwise malfunction without becoming totally inoperable. Based on the above
inventory and assessment, the estimated total cost of rendering the Computer
Systems Year 2000 Compliant is $125,000, which expenditure has been included in
the budget adopted by the Company. For purposes of this Agreement, "Year 2000
Compliant" means that all of the Computer Systems will correctly differentiate
between years in different centuries that end in the same two digits, and will
accurately process date/time data (including but not limited to calculating,
comparing and sequencing) from, into and between the twentieth and twenty-first
centuries, including leap year calculations.

    6.17.  ENVIRONMENTAL COMPLIANCE AND DISCLOSURE.

    (a)  Except as set forth on Schedule 6.17:

        (i)  no notice, notification, demand, request for information, citation,

    Company or any Subsidiary, is pending or threatened by any Person against,
    the Company or any Subsidiary, nor has any material penalty been assessed
    against the Company or any Subsidiary with respect to any (A) alleged

    the Company or any Subsidiary in violation of applicable Environmental Laws

    reasonably be expected to have a Material Adverse Effect.

Most Recent Balance Sheet or incurred since July 3, 1999 in the ordinary course
of business pursuant to credit facilities described in the Company's annual
report on Form 10-K for the year ended December 31, 1998; (ii) liens for Taxes
accrued but not yet payable; (iii) liens arising as a matter of law in the

                                      A-18

ordinary course of business with respect to obligations incurred after the date
of the Most Recent Balance Sheet, provided that the obligations secured by such
liens are not delinquent; and (iv) such imperfections of title and Encumbrances,
if any, as individually or in the aggregate would not reasonably be expected to
have a Material Adverse Effect (collectively "Permitted Liens"). Except as set
forth in Schedule 6.18, the Company and each of its Subsidiaries either own, or
have valid leasehold interests in, all properties and assets used by them in the
conduct of their business except where the absence of such ownership or
leasehold interest would not individually or in the aggregate reasonably be
expected to have a Material Adverse Effect.

    6.19.  MATERIAL CONTRACTS.  Schedule 6.19 sets forth a list of all
(i) Contracts for borrowed money or guarantees thereof involving a currently
outstanding principal amount in excess of $100,000, (ii) Contracts containing
non-compete covenants by the Company or any Subsidiary and (iii) other Contracts
(other than the Thermalloy Agreement) which involve the payment or receipt of
$1 million or more per year. All Contracts to which the Company or any of its
Subsidiaries is a party or by which any of their respective assets is bound are
valid and binding, in full force and effect and enforceable against the Company
or any of its Subsidiaries, as the case may be, and to the knowledge of the
Company, the other parties thereto in accordance with their respective terms,
subject to applicable bankruptcy, insolvency or other similar laws relating to
creditors' rights and general principles of equity, except where the failure to
be so valid and binding, in full force and effect or enforceable would not
individually or in the aggregate reasonably be expected to have a Material
Adverse Effect.

    6.20.  REQUIRED VOTE OF COMPANY STOCKHOLDERS.  Unless the Merger may be
consummated in accordance with Section 253 of the DGCL, the only vote of the
stockholders of the Company required to adopt this Agreement and approve the
Merger is the affirmative vote of the holders of a majority of the outstanding
shares of Common Stock.

    6.21.  INAPPLICABILITY OF CERTAIN RESTRICTIONS.  The action of the Board of
Directors of the Company in approving the Merger and this Agreement is
sufficient to render inapplicable to the Merger, the Voting Agreements and this
Agreement (and the transactions provided for herein) the provisions of
Section 203 of the DGCL assuming the representation and warranty contained in
the last sentence of Section 7.3 is true and correct.

    6.22.  RIGHTS PLAN.  The Company has not entered into, and its Board of
Directors has not adopted or authorized the adoption of, a shareholder rights or
similar agreement.

standing in each jurisdiction in which the nature of its business or the
ownership or leasing of its properties makes such qualification or licensing

Company and its Subsidiaries or of over 30% of any class of equity securities of
the Company or any of its Subsidiaries, (B) any tender offer (including a self

dilute the benefits to Purchaser of the transactions contemplated hereby
(collectively, "Acquisition Proposals"), or agree to or endorse any Acquisition
Proposal, (ii) enter into

                                      A-21

or participate in any discussions or negotiations regarding any of the

appropriate confidentiality letter (which letter shall not be less favorable to

concluded in good faith on the basis of advice from outside counsel that such
action by the Board of Directors is necessary in order to comply with the
fiduciary duties of the Board of Directors to the stockholders of the Company
under applicable law; PROVIDED, further, that if the Board of Directors of the
Company receives an Acquisition Proposal, then the Company shall promptly inform
Purchaser of the terms and conditions of such proposal and the identity of the
Person making it. Since June 7, 1999 the Company has not and has not permitted
its advisors, agents and other intermediaries to engage in any activities,
discussions or negotiations with any parties contacted prior to that date with
respect to any of the foregoing, and has used its reasonable best efforts to

all such information in the possession of any such party or in the possession of
any agent or advisor of any such party. In no event shall the Company enter into
a definitive agreement in connection with an Acquisition Proposal earlier than
two business days after the Purchaser receives the Company's initial
notification to Purchaser of an inquiry or proposal relating to such Acquisition
Proposal. As used in this Agreement, the term "Third Party" means any Person or
"group," as defined in Section 13(d) of the Exchange Act, other than Purchaser
or any of its affiliates.

have been made by a Third Party at any time on or after the date of this
Agreement and prior to the termination of this Agreement, and, (B) within
9 months of the termination of this Agreement pursuant to Section 10.1(b) or
Section 10.1(e)(i) any of the following events occurs (or the Company enters
into a definitive agreement with respect to any such event within a 6 month
period after termination of this Agreement and such transaction is subsequently
consummated) whereby stockholders of the Company receive, pursuant to such
event, cash, securities or other consideration having an aggregate value, when
taken together with the value of any securities of the Company or its
Subsidiaries otherwise held by the stockholders of the Company after such event,
in excess of the Merger Consideration: (1) the Company is acquired by merger or
otherwise by a Third Party; (2) a Third Party acquires more than 50% of the
total assets of the Company and its Subsidiaries, taken as a whole; (3) a Third
Party acquires more than 50% of the outstanding Common Stock; or (4) the Company

Stock or an extraordinary dividend relating to more than 50% of the outstanding
Common Stock or 50% of the assets of the Company and its Subsidiaries, taken as
a whole.

    (c)  If this Agreement is terminated because of a Company Breach (as defined
below), the Company shall reimburse Purchaser and its affiliates not later than
two business days after submission of reasonable documentation thereof for 100%
of their documented out-of-pocket fees and expenses (including the fees and
expenses of counsel) up to $1.5 million, in each case, actually incurred by any
of them or on their behalf in connection with this Agreement and the
transactions contemplated hereby (including the Merger and the arrangement,
obtaining the commitment to provide or obtaining the financing for the
transactions contemplated by this Agreement (including fees payable to the
financing entities and their respective counsel)). "Company Breach" means
(i) the Company shall have breached or failed to perform in any material respect
any of its covenants or agreements under this Agreement or any of the
representations and warranties of the Company set forth in this Agreement shall
not be true in any material respect when made or at any time prior to
consummation of the Merger as if made at and as of such time (except for
representations and warranties made as of a specific date, which shall be true
and correct in all material respects as of such date), and, in any such case,
such breach, failure to perform or misrepresentation shall not have been cured
within a reasonable period of time following Purchaser's notice to the Company
of such breach, failure to perform or misrepresentation, or (ii) a Thermalloy
Alteration (as defined in Section 9.2(c)). Purchaser and Merger Sub agree that,
in the absence of fraud, such payment shall be Purchaser and Merger Sub's
exclusive remedy for any Company Breach.

    (d)  The Company acknowledges that the agreements contained in this
Section 8.1 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, Purchaser would not enter into
this Agreement; accordingly, if the Company fails to promptly pay any amount due
pursuant to this Section 8.1, and, in order to obtain such payment, the other
party commences a suit which results in a judgment against the Company for the
fee or fees and expenses set forth in this Section 8.1, the Company shall also
pay to Purchaser its reasonable costs and expenses incurred in connection with
such litigation.

    (e)  Sections 8.1(b) and 8.1(c) shall survive any termination of this
Agreement, however caused.

    (f)  Any sale by Bowthorpe plc of Thermalloy to a Third Party shall not give
rise to any payment to the Purchaser or Merger Sub pursuant to this
Section 8.1.

Agreement, to respond promptly to all such comments of and requests by the SEC.
As promptly as practicable after the Proxy Statement has been cleared by the
SEC, the Company shall mail the Proxy Statement to the stockholders of the
Company. If at any time prior to the approval of this Agreement by the Company's
stockholders there shall occur any event that should be set forth in an
amendment or supplement to the Proxy Statement, the Company will prepare and

to an Acquisition Proposal exercised in a manner consistent with Section 8.1,
the Company, Purchaser, and Merger Sub shall: (i) use their reasonable best
efforts to cooperate with one another in (x) determining which filings are
required to be made prior to the Effective Time with, and which consents,
approvals, permits, authorizations or waivers are required to be obtained prior
to the Effective Time from, Governmental Entities or other third parties in
connection with the execution and delivery of this Agreement and any other
Ancillary Documents and the consummation of the transactions contemplated hereby
and thereby and (y) timely making all such filings and timely seeking all such
consents, approvals, permits, authorizations and waivers; and (ii) use their
reasonable best efforts to take, or cause to be taken, all other action and do,
or cause to be done, all other things necessary, proper or appropriate to
consummate and make effective the transactions contemplated by this Agreement
(including, in the case of the Purchaser and Merger Sub, obtaining the financing
necessary for the Merger and, if necessary, the Offer). If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purpose of this Agreement, the proper officers and directors of Purchaser
and the Surviving Corporation shall take all such necessary action.

    (b)  The Company shall promptly notify Purchaser of:

        (i)  any notice or other communication from any Person alleging that the
    consent of such Person is or may be required in connection with the
    transactions contemplated by this Agreement;

        (ii)  any notice or other communication from any governmental or
    regulatory agency or authority in connection with the transactions
    contemplated by this Agreement; and

        (iii)  any actions, suits, claims, investigations or proceedings
    commenced or, to the best of its knowledge threatened against, relating to
    or involving the Company or any Subsidiary which, if pending on the date of
    this Agreement, would have been required to have been disclosed pursuant to
    Section 6.9 or which relate to the consummation of the transactions
    contemplated by this Agreement.

    8.5.  ACCESS TO INFORMATION.

    (a)  From the date of this Agreement to the Closing, the Company shall, and
shall cause its Subsidiaries to, (i) give Purchaser and its authorized
representatives and lenders (and such lenders' counsel) reasonable access during
normal business hours to all books, records, personnel, offices and other
facilities and properties of the Company and its Subsidiaries and their
accountants and accountants' work papers provided that such access shall not
materially interfere with the normal business operations of the Company,
(ii) permit Purchaser to make such copies and inspections thereof as Purchaser
may reasonably request and (iii) furnish Purchaser with such financial and
operating data and other information with respect to the business and properties
of the Company and its Subsidiaries as Purchaser may from time to time
reasonably request; PROVIDED that no investigation or information furnished
pursuant to this Section 8.5 shall affect any representations or warranties made
by the Company in this Agreement or the conditions to the obligations of
Purchaser to consummate the transactions contemplated hereby.

    (b)  All such information and access shall be subject to the provisions of
the letter agreement between an affiliate of Purchaser and the Company dated as
of April 13, 1999 (the "Confidentiality Agreement") relating to the confidential
treatment of "Evaluation Material" (as defined therein).

    8.6.  PUBLICITY.  Purchaser and Merger Sub, on the one hand, and the
Company, on the other hand, will consult with each other before issuing, and
give each other the opportunity to review and comment upon, any press release or
other public statements or filing with any Governmental Entity with respect to
the transactions contemplated by this Agreement, including the Merger, and shall
not issue any such press release or make any such public statement or filing
prior to such consultation, except as may be required by applicable law, court
process or by obligations pursuant to any listing agreement with any national
securities exchange or the Nasdaq National Market. The parties agree that the
initial press release to be issued with respect to the transactions contemplated
by this Agreement shall be in the form heretofore agreed to by the parties.

    8.7.  FURTHER ACTION; COOPERATION CONCERNING CERTAIN LITIGATION.  Each party
to this Agreement shall, subject to the fulfillment at or before the Effective
Time of each of the conditions of performance set forth in this Agreement or the
waiver thereof, perform such further acts and execute such documents as may be
reasonably required to effect the Merger. If there shall be any judgment,
injunction, order or decree enjoining Purchaser or the Company from consummating
the Merger, each party to this Agreement shall use its reasonable best efforts
to lift such judgment, injunction order or decree.

    8.8.  INSURANCE; INDEMNITY.

    (a)  For a period of not less than six years after the Effective Time, the
Surviving Corporation shall indemnify, defend and hold harmless the present and
former officers and directors of the Company (the "Company Indemnified Persons")
in respect of all losses, claims, damages, costs, expenses (including counsel
fees and expenses), settlement, payments or liabilities arising out of or in
connection with any claim, demand, action, suit, proceeding or investigation
based in whole or in part on or arising in whole or in part out of the fact that
such Person is or was an officer or director of the Company or any of its
Subsidiaries, whether or not pertaining to any matter existing or occurring at
or prior to the Effective Time (including without limitation matters related to
the transactions contemplated by this Agreement), whether or not claimed or
asserted prior to or after the Effective Time. The Surviving Corporation shall
periodically advance expenses as incurred by the Company Indemnified Persons
with respect to the foregoing to the fullest extent permitted under applicable
law provided that the Person to whom the expenses are advanced provides an
undertaking to repay such advance if it is ultimately determined that such
Person is not entitled to indemnification.

    (b)  For six years after the Effective Time, the Surviving Corporation shall
use its reasonable best efforts to provide officers' and directors' liability
insurance in respect of acts or omissions occurring

                                      A-27

prior to and including the Effective Time covering each such Person currently
covered by the Company's officers' and directors' liability insurance policy on
terms with respect to coverage and amount no less favorable than those of such
policy in effect on the date hereof; PROVIDED that in satisfying its obligation
under this Section, the Surviving Corporation shall not be obligated to pay
premiums in excess of 200% of the amount per annum the Company paid in its last
full fiscal year, which amount has been disclosed to Purchaser; and PROVIDED
further that if the annual premiums of such insurance coverage shall exceed such
amount, the Surviving Corporation shall be obligated to obtain a policy with the
greatest coverage available for a cost not exceeding such amount. It is
understood that such obligation to indemnify (but not to maintain insurance)
shall apply to claims of which the Surviving Corporation shall have been
notified prior to the expiration of such six-year period regardless of when such
claims shall have been disposed of.

    (c)  For a period of six years from and after the Effective Time, the
Certificate of Incorporation and Bylaws of the Surviving Corporation and its
Subsidiaries shall include provisions for the limitation of liability of
directors and indemnification of the Company Indemnified Persons to the fullest
extent permitted under applicable law and shall not, unless required by
applicable law, be amended in any manner materially adverse to the Company
Indemnified Persons without the prior written consent of such Persons. From and
after the Effective Time, the Surviving Corporation shall fulfill and honor in
all respects the obligations of the Company pursuant to any indemnification
agreements between the Company or any Subsidiary and their respective directors
and officers as of or prior to the date of this Agreement and any
indemnification provisions under the Company's or any Subsidiary's Certificate
of Incorporation or Bylaws as in effect as of the date of this Agreement.

    (d)  The Surviving Corporation shall pay all expenses, including reasonable
attorney's fees, that may be incurred by any Indemnified Person (as defined
below) in enforcing the indemnity and other obligations provided for in this
Section 8.8.

    (e)  If requested by an Indemnified Person, any determination to be made as
to whether any Indemnified Person has met any standard of conduct imposed by law
shall be made by legal counsel reasonably acceptable to such Indemnified Person
and the Surviving Corporation, retained at the Surviving Corporation's expense.

    (f)  In the event the Surviving Corporation or any of its successors or
assigns (i) consolidates with or merges into any other Person and shall not be
the continuing or surviving corporation or entity of such consolidation or
merger or (ii) transfers all or substantially all of its properties and assets
to any Person, then and in each such case, proper provisions shall be made so
that the successors and assigns of the Surviving Corporation shall assume the
obligations set forth in this Section 8.8.

    (g)  If the Merger shall have been consummated, the Surviving Corporation
shall, to the fullest extent permitted under applicable law, indemnify and hold
harmless Purchaser and any Person or entity who was a stockholder, officer,
director or affiliate of Purchaser prior to the Effective Time against any
Losses in connection with any litigation arising out of or pertaining to any of
the transactions contemplated by this Agreement or the Ancillary Documents.
Purchaser shall periodically advance expenses as incurred with respect to the
foregoing to the fullest extent permitted under applicable law provided that the
Person to whom the expenses are advanced provides an undertaking to repay such
advance if it is ultimately determined that such Person is not entitled to
indemnification.

    (h)  If any litigation described in paragraph (a) or (g) of this
Section 8.8 (each, an "Action") arises or occurs, the Surviving Corporation
shall control the defense of such Action through its counsel, provided that such
counsel shall be reasonably acceptable to the Person to whom indemnity is being
provided (the "Indemnified Persons"), and the Indemnified Persons shall be
permitted to participate in the defense of such Action through such counsel of
their choice but such counsel shall be solely at the Indemnified Person's
expense. If there is any conflict between the Surviving Corporation and any
Indemnified Persons or there are additional defenses available to any
Indemnified Persons, the

                                      A-28

Indemnified Persons shall be permitted to participate in the defense of such
Action with counsel selected by the Indemnified Persons, which counsel shall be
reasonably acceptable to the Surviving Corporation and the reasonable fees and
expenses of which counsel shall be paid by the Surviving Corporation; PROVIDED
that the Surviving Corporation shall not be obligated to pay the reasonable fees
and expenses of more than one counsel for all Indemnified Persons in any single
Action except to the extent that, in the opinion of counsel for the Indemnified
Persons, two or more of such Indemnified Persons have conflicting interests in
the outcome of such Action. The Surviving Corporation shall not be liable for
any settlement effected without its written consent, which consent shall not
unreasonably be withheld.

    (g)  This Section 8.8 shall survive the consummation of the Merger at the
Effective Time, is intended to benefit the Company, Purchaser, the Surviving
Corporation and the Indemnified Persons, and shall be binding on all successors
and assigns of the Surviving Corporation. So long as the Purchaser holds
securities permitting the Purchaser to elect at least a majority of the members
of the Board of Directors of the Surviving Corporation, the Purchaser shall
cause the Surviving Corporation to comply with its obligations under this
Section 8.8.

    8.9  EMPLOYEE BENEFIT PLANS.

    (a)  From and after the Effective Time, unless the Surviving Corporation and
an officer, director or employee of the Company otherwise agree, the Surviving
Corporation and its respective Subsidiaries will honor and assume, in accordance
with their terms, all existing employment and severance agreements between the
Company or any of its Subsidiaries and any officer, director, or employee of the
Company or any of its Subsidiaries and all benefits or other amounts earned or
accrued to the extent vested or which become vested in the ordinary course under
all employee benefit plans of the Company and any of its Subsidiaries.

    (b)  Purchaser confirms that it is Purchaser's intention that, until the
first anniversary of the Effective Time, subject to applicable law, the
Surviving Corporation and its Subsidiaries will provide salary, benefits and
equity-based compensation to their employees which will, in the aggregate, be
comparable to those currently provided by the Company and its Subsidiaries to
their employees. Notwithstanding the foregoing, nothing in this Agreement shall
obligate or require the Surviving Corporation or any of its Subsidiaries to
provide its employees with a plan or arrangement similar to any equity-based
compensation plans currently maintained by the Company and nothing in this
Agreement shall otherwise limit the Surviving Corporation's right to amend,
modify or terminate any Employee Plan or Benefit Arrangement. Purchaser intends
that, after the first anniversary of the Effective Time, the Surviving
Corporation and its Subsidiaries will provide benefits to their employees
(excluding employees covered by collective bargaining agreements, if any) which
benefits are appropriate in the judgment of the Surviving Corporation, taking
into account all relevant factors, including, without limitation, the businesses
in which the Surviving Corporation and its Subsidiaries are engaged.

    (c)  The Company shall terminate its 1995 Employee Stock Purchase Plan (the
"ESPP"), including all employee salary deductions in connection therewith, on or
before the Closing Date. On the Closing Date, all accumulated employee salary
deductions shall be applied to the purchase of whole shares of Company Common
Stock in accordance with the terms of the ESPP and any remaining employee salary
deductions shall be returned to participants without interest. The shares of
Company Common Stock to be delivered by the Company pursuant to the ESPP shall
be converted into cash on the Closing Date in accordance with Article 4, without
further action by any participant. Further, the Company shall immediately amend,
effective as of the date hereof, the ESPP to suspend any new offering periods or
stock purchases after the date hereof (and any increases in employee salary
deductions thereunder) except employees currently participating therein may
continue to purchase stock in the current offering period in accordance with
their current salary deduction election or may reduce the amount of their salary
deduction election through the Closing Date. The Company shall promptly notify
Purchaser of any changes in employee salary deductions and the number of shares
of Company Common Stock hereafter acquired under the ESPP.

parties.

                            CONDITIONS OF THE OFFER

    Notwithstanding any other provision of the Offer, Purchaser shall not be
required to accept for payment or pay for any shares of Common Stock, and may

    reasonable judgment, has a reasonable likelihood of success,
    (i) challenging or seeking to make illegal, to delay materially or otherwise
    directly or indirectly to restrain or prohibit the making of the Offer, the
    acceptance for payment of or payment for some of or all the shares of Common
    Stock by Purchaser or the consummation by Purchaser of the Merger, or
    seeking to obtain material damages, (ii) seeking to restrain or prohibit

    result in any of the consequences referred to in clauses (i) through
    (iv) of paragraph (a) above; or

        (c)  there shall have occurred any event or any worsening, after the
    date of the Agreement, of any condition existing on the date of this
    Agreement which, individually or in the aggregate, has or could reasonably
    be expected to have a Material Adverse Effect; or

        (d)  a tender or exchange offer for more than 30% of the shares of
    Common Stock at a price per Share in excess of the Offer Consideration shall
    have been made by another person, or it shall have been publicly disclosed
    or Purchaser shall have otherwise learned that (i) any person or "group" (as
    defined in Section 13(d)(3) of the Exchange Act) shall have acquired
    beneficial ownership of more than 30% of any class or series of capital
    stock of the Company (including the shares of Common Stock), through the
    acquisition of stock, the formation of a group or otherwise, or shall have
    been granted any option, right or warrant, conditional or otherwise, to
    acquire beneficial ownership of more than 30% of any class or series of
    capital stock of the Company (including the shares of Common Stock) other
    than acquisitions for bona fide arbitrage purposes only and other than as
    disclosed in a Schedule 13D or 13G on file with the Commission on

                                     A-A-1

    August 23, 1999, or (ii) any such person or group which, prior to
    August 23, 1999, had filed such a Schedule with the Commission shall have
    acquired beneficial ownership of additional shares of any class or series of
    capital stock of the Company (including the shares of Common Stock), through
    the acquisition of stock, the formation of a group or otherwise,
    constituting 10% or more of any such class or series, or shall have been
    granted any option, right or warrant, conditional or otherwise, to acquire
    beneficial ownership of additional shares of any class or series of capital
    stock of the Company (including the shares of Common Stock) constituting 10%
    or more of any such class or series or (iii) any person or group shall have
    entered into a definitive agreement or an agreement in principle with
    respect to a merger, consolidation or other business combination with the
    Company; or

        (e)  the Company shall have breached or failed to perform in any
    material respect any of its covenants or agreements under the Merger
    Agreement or any of the representations and warranties of the Company set
    forth in the Merger Agreement shall not be true in any material respect when
    made or at any time prior to consummation of the Offer as if made at and as
    of such time (except for representations and warranties made as of a
    specific date, which shall be true and correct in all material respects as
    of such date); or

        (f)  the Merger Agreement shall have been terminated in accordance with
    its terms; or

        (g)  the Board of Directors of the Company shall have withdrawn or
    materially modified its approval or recommendation of the Offer or the
    Merger; or

        (h)  the Company and Purchaser shall have reached an agreement or
    understanding regarding termination of the Offer;

which, in the reasonable judgment of Purchaser in any such case, and regardless
of the circumstances giving rise to any such condition, makes it inadvisable to
proceed with such acceptance for payment or payment.

    The foregoing conditions are for the sole benefit of Purchaser and Merger
Sub and may be asserted by Purchaser or Merger Sub regardless of the
circumstances (including any action or inaction by Purchaser or the Company)
giving rise to any such condition and may be waived by Purchaser or Merger Sub,
in whole or in part, at any time and from time to time, in the sole discretion
of Purchaser. The failure by Purchaser or Merger Sub at any time to exercise any
of the foregoing rights will not be deemed a waiver of any right, the waiver of
such right with respect to any particular facts or circumstances shall not be
deemed a waiver with respect to any other facts or circumstances, and each right
will be deemed an ongoing right which may be asserted at any time and from time
to time.

    Should the Offer be terminated pursuant to the foregoing provisions, all
tendered shares of Common Stock not previously accepted for payment shall
forthwith be returned by the depositary to the tendering stockholders.

    The capitalized terms used in this Exhibit A shall have the meaning set
forth in the Agreement to which it is annexed.

August 22, 1999

Confidential

The Board of Directors
Aavid Thermal Technologies, Inc.
One Eagle Square, Suite 509
Concord, NH 03301

Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to the holders of the outstanding shares of common stock (respectively, the
"Shareholders" and the "Common Stock" or the "Common Shares") of Aavid Thermal
Technologies, Inc. (the "Company"), of the consideration to be received by such
shareholders in connection with the proposed acquisition of all outstanding
shares of the Company, pursuant to the Agreement and Plan of Merger dated August
16, 1999 (the "Agreement") between Heat Holdings Corp., ("Purchaser"), Heat
Merger Corp., ("Merger Sub", a wholly owned subsidiary of Purchaser), and the
Company.

We understand that the terms of the Agreement provide, among other things, that
at the Effective Time, as defined in the Agreement, the Merger Sub will be
merged with and into the Company, and each Common Share of the Company will be
converted into the right to receive a cash payment, without interest, of $25.50.
We understand that under the terms of the Agreement, the right to receive a cash
payment of $25.50 is subject to the Company's acquisition of certain direct and
indirect Subsidiaries (such Subsidiaries, collectively, "Thermalloy") of
Bowthorpe plc pursuant to the terms and conditions of the Stock Purchase
Agreement dated as of August 23, 1999 among the Company, Bowthorpe plc,
Bowthorpe B.V., Bowthorpe International Inc., and Bowthorpe GmbH, as in effect
on the date of the Agreement (the "Thermalloy Agreement"). We also understand
that if the Thermalloy Agreement is terminated prior to the Company's
acquisition of Thermalloy, then Merger Sub will, under the terms of the
Agreement, commence an offer to purchase all outstanding shares of Company
Common Stock at a price of $24.50 per share in cash. Together, these two
alternatives comprise the "Proposed Transaction" as set forth in the Agreement.
For purposes of this opinion, we have assumed that both the Proposed
Transaction, and the Thermalloy acquisition, will be accounted for as purchase
transactions.

Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment banking
services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. We have acted as a financial advisor to the Board of
Directors of the Company in connection with the Proposed Transaction, and we
will receive a fee for our services, which include the rendering of this
opinion.

In the ordinary course of business, Hambrecht & Quist acts as a market maker and
broker in the publicly traded securities of the Company and receives customary
compensation in connection therewith. In the ordinary course of business,
Hambrecht & Quist actively trades in the equity and derivative securities of the
Company for its own account and for the accounts of its customers and,
accordingly, may at any time hold a long or short position in such securities.
Hambrecht & Quist may in the future provide additional investment banking or
other financial advisory services to the Company.

In connection with our review of the Proposed Transaction, and in arriving at
our opinion, we have, among other things:

    (i) reviewed with the Board of Directors and members of management the
       Company's financial plans, its strategic plans and business alternatives;

    (ii) assisted the Company in the evaluation and selection of potential
       acquirers and represented the Company in contacting, qualifying and
       negotiating with the potential acquirer;

    (iii) met with the Board of Directors and members of management to discuss
       the Company's position and recommendations to stockholders concerning the
       proposal to acquire the Company, as well as strategic alternatives and
       their financial implications;

    (iv) assisted the Company in the preparation of confidential descriptive
       materials for review by potential acquirers in connection with their
       evaluation of a sale transaction;

    (v) offered our counsel with respect to the adequacy of the consideration
       offered in any proposal to acquire the Company;

    (vi) discussed the business, financial condition and prospects of the
       Company with certain members of senior management;

    (vii) reviewed the recent reported prices and trading activity for the
       common stocks of the Company and compared such information and certain
       financial information for the Company with similar information for
       certain other companies engaged in businesses we consider comparable;

  (viii) reviewed the financial terms, to the extent publicly available, of
         certain comparable merger and acquisition transactions;

    (ix) reviewed the Agreement; and

    (x) conducted such other studies and inquiries, and reviewed such other
       data, as we have deemed relevant.

In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information, publicly available or provided to us,
concerning the Company considered in connection with our review of the Proposed
Transaction, and we have not assumed any responsibility for independent
verification of such information. We have not prepared any independent valuation
or appraisal of any of the assets or liabilities of the Company, nor have we
conducted a physical inspection of the properties and facilities of either
company. With respect to the financial forecasts and projections made available
to us and used in our analysis, we have assumed that they reflect the best
currently available estimates and judgments of the expected future financial
performance of the Company. Our opinion is necessarily based upon market,
economic, financial and other conditions as they exist and can be evaluated as
of the date of this letter and any change in such conditions would require a
reevaluation of this opinion. In rendering this opinion, we have assumed that
the proposed purchase will be consummated substantially on the terms set forth
in the Agreement, without any waiver of any material terms or conditions by any
party thereto. Furthermore, we express no opinion on the fairness of any other
potential transaction between the Company, the Purchaser, the Merger Sub, the
Shareholders or any other parties, including, but not limited to, the potential
acquisition of certain stock and or assets of certain direct or indirect
subsidiaries of Bowthorpe, plc pursuant to the terms and conditions of the
Thermalloy Agreement.

It is understood that this letter is for the information of the Board of
Directors only and may not be used for any other purpose without our prior
written consent; provided, however, that this letter may be reproduced in full
in the Proxy Statement, and may be referenced in the Offer Documents and
Schedule 14D-9, as defined in the Agreement, so long as any description or
reference to Hambrecht & Quist or any summary of the opinion included therein,
is in a form and substance acceptable to us and our legal counsel. This letter
does not constitute a recommendation to any stockholder as to how such
stockholder should vote on the Proposed Transaction.

Based upon and subject to the foregoing and after considering such other matters
as we deem relevant, we are of the opinion that as of the date hereof (i) the
receipt of a cash payment of $25.50 per outstanding share of Common Stock is
fair to the Shareholders from a financial point of view if Thermalloy is
acquired under the terms of the Thermalloy Agreement,

and (ii) the receipt of a cash payment of $24.50 per outstanding share of Common
Stock is fair to the Shareholders from a financial point of view if Thermalloy
is not acquired under the terms of the Thermalloy Agreement.

Very truly yours,

HAMBRECHT & QUIST LLC

DELAWARE GENERAL CORPORATION LAW

Section 262. Appraisal rights.

(a) Any stockholder of a corporation of this State who holds shares of stock on
the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to Section 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a non stock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a non stock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of
stock of a constituent corporation in a merger or consolidation to be effected
pursuant to Section 251 (other than a merger effected pursuant to Section 251(g)
of this title), Section 252, Section 254, Section 257, Section 258, Section 263
or Section 264 of this title:

    (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of Section 251 of this title.

    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under
this section shall be available for the shares of any class or series of stock
of a constituent corporation if the holders thereof are required by the terms of
an agreement of merger or consolidation pursuant to SectionSection 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

        a. Shares of stock of the corporation surviving or resulting from such
    merger or consolidation, or depository receipts in respect thereof;

        b. ]Shares of stock of any other corporation, or depository receipts in
    respect thereof, which shares of stock (or depository receipts in respect
    thereof) or depository receipts at the effective date of the merger or
    consolidation will be either listed on a national securities exchange or
    designated as a national market system security on an interdealer quotation
    system by the National Association of Securities Dealers, Inc. or held of
    record by more than 2,000 holders;

        c. Cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a. and b. of this paragraph; or

        d. Any combination of the shares of stock, depository receipts and cash
    in lieu of fractional shares or fractional depository receipts described in
    the foregoing subparagraphs a., b. and c. of this paragraph.

                                      C-1

    (3) In the event all of the stock of a subsidiary Delaware corporation party
to a merger effected under Section 253 of this title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections
(d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

    (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsection (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of
such stockholder's shares shall deliver to the corporation, before the taking of
the vote on the merger or consolidation, a written demand for appraisal of such
stockholder's shares. Such demand will be sufficient if it reasonably informs
the corporation of the identity of the stockholder and that the stockholder
intends thereby to demand the appraisal of such stockholder's shares. A proxy or
vote against the merger or consolidation shall not constitute such a demand. A
stockholder electing to take such action must do so by a separate written demand
as herein provided. Within 10 days after the effective date of such merger or
consolidation, the surviving or resulting corporation shall notify each
stockholder of each constituent corporation who has complied with this
subsection and has not voted in favor of or consented to the merger or
consolidation of the date that the merger or consolidation has become effective;
or

    (2) If the merger or consolidation was approved pursuant to Section 228 or
Section 253 of this title, each constituent corporation, either before the
effective date of the merger or consolidation or within ten days thereafter,
shall notify each of the holders of any class or series of stock of such
constituent corporation who are entitled to appraisal rights of the approval of
the merger or consolidation and that appraisal rights are available for any or
all shares of such class or series of stock of such constituent corporation, and
shall include in such notice a copy of this section; provided that, if the
notice is given on or after the effective date of the merger or consolidation,
such notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or resulting
corporation shall send such a second notice to all such holders on or within
10 days after such effective date; provided, however, that if such second notice
is sent more than 20 days following the sending of the first notice, such second
notice need only be sent to each stockholder who is entitled to appraisal rights
and who has demanded appraisal of such holder's shares in accordance with this
subsection. An affidavit of the secretary or assistant secretary or of the
transfer

agent of the corporation that is required to give either notice that such notice
has been given shall, in the absence of fraud, be prima facie evidence of the
facts stated therein. For purposes of determining the stockholders entitled to
receive either notice, each constituent corporation may fix, in advance, a
record date that shall be not more than 10 days prior to the date the notice is
given, provided, that if the notice is given on or after the effective date of
the merger or consolidation, the record date shall be such effective date. If no
record date is fixed and the notice is given prior to the effective date, the
record date shall be the close of business on the day next preceding the day on
which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the
surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail and by publication shall be approved by the Court, and
the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders
who have complied with this section and who have become entitled to appraisal
rights. The Court may require the stockholders who have demanded an appraisal
for their shares and who hold stock represented by certificates to submit their
certificates of stock to the Register in Chancery for notation thereon of the
pendency of the appraisal proceedings; and if any stockholder fails to comply
with such direction, the Court may dismiss the proceedings as to such
stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall
appraise the shares, determining their fair value exclusive of any element of
value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or

                                      C-3

resulting corporation or by any stockholder entitled to participate in the
appraisal proceeding, the Court may, in its discretion, permit discovery or
other pretrial proceedings and may proceed to trialupon the appraisal prior to
the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

(i) The Court shall direct the payment of the fair value of the shares, together
with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances. Upon application
of a stockholder, the Court may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorney's fees and the fees and expenses of
experts, to be charged pro rata against the value of all the shares entitled to
an appraisal.

(k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

(l) The shares of the surviving or resulting corporation to which the shares of
such objecting stockholders would have been converted had they assented to the
merger or consolidation shall have the status of authorized and unissued shares
of the surviving or resulting corporation.
