ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.


         On October 21, 1999, Aavid Thermal Technologies, Inc. (the "Company")
acquired the Thermalloy Division of Bowthorpe plc. The Thermalloy Division's
business is substantially similar to the Company's thermal management products
business. As part of the acquisition from Bowthorpe, the Company 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 addition, on October 28, 1999 the Company
purchased an additional 20.2% of Curamik from the two minority shareholders of
Curamik for approximately $2.7 million, thereby increasing its 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 under Item 5
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
the Company, 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; Monterey,
Mexico; Swindon, England; Corby, England; Milan, 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 first nine months of 1999.


         The Company's future success will depend, in part, on its 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 Aavid's and the coordination
of their sales and marketing and financial reporting efforts with Aavid's. There
can be no assurance that the Company will accomplish the integration smoothly or
successfully or that Aavid 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 the Company's day-to-day business.



                                       -2-

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


ITEM 5.  OTHER EVENTS.

         On October 21, 1999, in connection with the closing of the acquisition
of the Thermalloy Division, the Company 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, pay transaction costs and provide working capital to the
Thermalloy Division, 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 the Company's 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 Aavid and (y) a margin of between one and one-half
percent and two percent (depending on the Company's 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 the Company's
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 the Company's 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 its stock and to merge or consolidate
with any other person other than the previously announced merger with an entity
formed by Willis Stein & Partners. In addition, the Credit Facility requires
that the Company meet certain financial ratios, and provides the banks with the
right to require the payment


                                       -3-



<PAGE>   4



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 with entities formed by Willis Stein & Partners. The
Credit Facility is guaranteed by all of the Company's domestic subsidiaries and
secured by the Company's assets (including the assets and stock of its domestic
subsidiaries and a portion of the stock of its foreign subsidiaries).

                         REPORT OF INDEPENDENT AUDITORS





To   The Board of Directors

     Bowthorpe plc



We have audited the combined balance sheets of Thermalloy Group as at December
31, 1998 and 1997, and the related combined profit and loss accounts and
combined statements of total recognized gains and losses, movements in invested
capital and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of Thermalloy
Group's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with United Kingdom generally accepted
auditing standards which do not differ in any significant respect from United
States generally accepted auditing standards. Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the combined financial position of Thermalloy Group at
December 31, 1998 and 1997, and the combined results of its operations, and its
combined cash flows for each of the three years in the period ended December 31,
1998 in conformity with accounting principles generally accepted in the United
Kingdom which differ in certain respects from those generally accepted in the
United States (see Note 21 of Notes to Combined Financial Statements).

                                THERMALLOY GROUP

                     NOTES TO COMBINED FINANCIAL STATEMENTS


1.  BASIS OF PREPARATION

These financial statements are a combination of the financial statements of the
thermal management companies of Bowthorpe Group comprising Thermalloy Inc.,
Redpoint Thermalloy Limited, Redpoint Limited, Thermalloy Investment Company
Inc., Thermalloy SA de CV, Thermalloy Limited, Thermalloy International Limited,
Elbomec Thermalloy SRL, Thermalloy (Malaysia) Sdn Bhd, Curamik Electronics GmbH,
Curamik Electronics Inc. (together, "Thermalloy Group") of Bowthorpe plc, a UK
company, including purchased goodwill arising on Bowthorpe's acquisition of
these companies. These financial statements have been prepared in conjunction
with the planned divestiture of Thermalloy Group.

These combined financial statements have been prepared in accordance with
accounting principles generally accepted in the United Kingdom ("UK GAAP"). All
intra-Thermalloy Group transactions and balances have been eliminated on
combination.

The combined financial statements include interest income and expense actually
earned or paid by Thermalloy Group. During the three years ended December 31,
1998, Thermalloy Group's operations were principally funded by share capital,
loans from Bowthorpe Group companies and loans from third parties. These
financing arrangements were designed and implemented on a Bowthorpe Group basis,
rather than from the perspective of the financing needs of Thermalloy Group. The
decisions as to whether to finance companies with share capital or loans and as
to whether to charge interest on any particular loan were taken based on the
financial position of the companies and local taxation considerations. Where
interest was charged, the rate charged varied, but was generally in line with
commercial borrowing rates. The Bowthorpe Group loans generally did not have set
repayment terms.

The combined financial statements reflect the actual tax charges suffered by the
entities within Thermalloy Group.

The combined financial statements reflect management costs charged to the
Thermalloy Group by the Bowthorpe Group based either on direct costs incurred or
on assets employed. Management believes this is a reasonable basis.

The basis of funding, interest charges and financing cash flows and related cash
flows and management charges are not necessarily representative of those that
would have been incurred by Thermalloy Group on a stand alone basis, or of those
that may be incurred by Thermalloy Group in the future.

The combined financial statements are presented in US dollars, although
Bowthorpe Group's functional currency is the pound sterling. The following
exchange rates have been used to translate to US dollars:

2.  ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The combined financial statements are prepared under the historical cost
convention and in accordance with applicable UK accounting standards and
specifically in accordance with the following accounting policies.

INTANGIBLE ASSETS

As permitted by FRS 10, goodwill arising on the acquisition of a subsidiary
undertakings prior to January 1, 1998 representing the excess of cost over the
fair value of the attributable assets and liabilities acquired has been written
off against profit and loss account reserve. In accordance with UITF 3, goodwill
which has been written off the profit and loss account reserve would be charged
to the profit and loss account on the subsequent disposal of the business to
which it related.

Other separately identifiable intangible assets such as patent fees, licence
fees and trade marks are capitalised in the balance sheet only when the value
can be measured reliably or the intangible asset is purchased in the acquisition
of a business. Such intangible assets are amortised over their useful economic
lives up to a maximum of 20 years. The carrying value of intangible assets is
reviewed for impairment at the end of the first full year following acquisition
and in other periods if events or changes in circumstances indicate the carrying
value may not be recoverable.

FOREIGN CURRENCIES


Transactions in foreign currencies are recorded at the rates of exchange ruling
at the date of the transaction. Assets and liabilities denominated in foreign
currencies are translated into sterling at the rates of exchange ruling at the
balance sheet date.

On combination, the results of overseas entities are translated into sterling
using average rates of exchange for the period. Exchange differences arising
from the translation of opening net assets of overseas entities are taken direct
to shareholders' equity. All other exchange differences are charged to income.


SALES


Sales represent the amounts shipped and invoiced to customers for goods and
services during the year, excluding tax and intra-group transactions.


PRODUCT DEVELOPMENT

Product development expenditure is charged to profit and loss account in the
year in which it is incurred.

PENSION COSTS

In the United Kingdom the Bowthorpe Group operates two pension schemes for the
benefit of employees. These schemes require contributions to be made to
separately administered funds, based on triennial actuarial valuations.

               NOTES TO COMBINED FINANCIAL STATEMENTS (continued)


2.  ACCOUNTING POLICIES (continued)

PENSION COSTS

Contributions to the Bowthorpe Group United Kingdom and United States defined
benefit pension schemes are charged to the profit and loss account so as to
spread the cost of pensions over the employees' working lives within the
Bowthorpe Group. Differences between the amounts funded and the amounts charged
to profit and loss account are treated as either creditors or prepayments in the
balance sheet. Variations in the pension costs, which are identified as a result
of actuarial valuations, are amortised over the average expected working lives
of employees.

Contributions payable to Bowthorpe Group's other plans are charged to profit and
loss account in the year for which they are due.

DEFERRED TAXATION

Deferred taxation is provided using the liability method on all timing
differences to the extent that they are expected to reverse in the future,
calculated at the rate at which it is estimated that tax will be payable.

INVENTORIES

Inventories are valued at the lower of cost and estimated net realisable value.
Cost includes all costs in bringing each product to its present location and
condition, being the full manufacturing cost on a first in, first out basis,
including all attributable overheads based on a normal level of activity. Net
realisable value represents selling prices less further costs to be incurred to
completion and on sale.

TANGIBLE ASSETS

Depreciation is not provided on freehold land where the value is separately
identifiable. Depreciation is provided to write off all other assets over their
estimated useful lives at rates which take into account commercial conditions at
their location. Usual asset lives are as follows:

The carrying values of tangible fixed assets are reviewed for impairment in
periods where events or changes in circumstances indicate the carrying value may
not be recoverable.

Assets obtained under finance leases and hire purchase contracts are capitalised
in the balance sheet and are depreciated over their estimated useful lives. The
interest elements of the rental obligations are charged to the profit and loss
account over the periods of the leases and hire purchase contracts in proportion
to the balance of capital repayments outstanding.

Operating lease rentals are charged to profit and loss account over the period
of the lease.

6. PENSION AND OTHER POST-RETIREMENT BENEFITS

The principal Bowthorpe pension plans are a funded defined benefit plan and a
defined contribution plan with a defined benefit underpin in the United Kingdom,
and a defined contribution plan in the United States. Contributions to the
Bowthorpe UK plans are made in accordance with the recommendations of the
independent actuary of the relevant plan.

The latest actuarial valuations of the Bowthorpe UK defined benefit plans were
undertaken as at April 1, 1997 using the projected unit credit method and the
principal results and assumptions were as follows:

ASSUMPTION                       STAFF PENSION PLAN      RETIREMENT CASH PLAN
- ----------                       ------------------      --------------------
Return on investments                    9.0% pa                 9.0% pa
Salary inflation average                 6.5% pa                 6.0% pa
Price inflation                          4.5% pa                 4.5% pa
Pension increases                        4.5% pa                 4.5% pa
Dividend growth                         4.75% pa                4.75% pa
Market value of assets       (pound)72.4 million      (pound)3.8 million
Level of funding                            114%                     99%
Employer contribution rate                  7.5%                      6%

The level of funding represents the actuarial value of assets expressed as a
percentage of the value of liabilities that have accrued to members after
allowing for the assumed future increases in salary. For accounting purposes in
accordance with SSAP24, the actuarial surplus is being spread over the average
expected remaining service of plan members being 13 years.

With the exception of the United States defined benefit schemes, contributions
payable to other Bowthorpe Group overseas plans are charged to profit and loss
account in the year for which they are due.

those that would have been incurred by Thermalloy Group on a stand-alone basis
or that will be incurred by Thermalloy Group in the future.

8.  TAXATION

The companies within Thermalloy Group have calculated tax on their own results
with no account taken of other Bowthorpe Group companies for the three years
ended December 31, 1998. Where tax has been borne by individual companies within
Thermalloy Group, these amounts are included in the combined financial
statements.

               NOTES TO COMBINED FINANCIAL STATEMENTS (continued)


20.   RELATED PARTY DISCLOSURE

Thermalloy Group does not operate as a separate group and consequently there
were a number of related party transactions between its companies and other
companies and businesses within Bowthorpe Group. These include transactions
relating to insurance, treasury and taxation, together with other central
services supplied by Bowthorpe Group to Thermalloy Group. These transactions
have not been identified individually as it is not practical to do so.

21.   DIFFERENCES BETWEEN UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED
      ACCOUNTING PRINCIPLES

The combined financial statements are prepared in accordance with accounting
principles generally accepted in the United Kingdom ("UK GAAP"), which differ in
certain respects from those generally accepted in the United States ("US GAAP").
The significant differences applicable to Thermalloy Group are described below.

Goodwill

Under UK GAAP, goodwill arising on acquisitions prior to January 1, 1998 was
written off to reserves. Under US GAAP, such goodwill would be capitalized and
amortized to the income statement over the estimated useful lives of the assets
over its estimated useful lives not exceeding 40 years. For the purpose of the
US GAAP reconciliations, goodwill is amortized over 20 years.

Under US GAAP, if any impairment indicators were present, the Group would
evaluate the recoverability of goodwill and other intangible fixed assets, based
on undiscounted cash flows.

Taxation

Under UK GAAP, deferred taxation is provided using the liability method in
respect of timing differences. Provision is made, or recovery anticipated, where
timing differences are expected to reverse without replacement in the
foreseeable future. US GAAP requires taxes to be computed on a stand-alone basis
by a member of a group if it issues separate financial statements.

Under US GAAP, deferred taxation is provided on the full liability basis on all
temporary differences between the tax and book bases of assets and liabilities
including the differences between the assigned fair values and tax bases of
assets and liabilities acquired. Future taxation benefits are recognized as
deferred taxation assets, subject to a valuation allowance to the extent that it
is more likely than not that any part will not be realized.

There are no material differences in deferred taxation resulting from the
application of US GAAP.

Pensions

The Group provides for the cost of retirement benefits based upon consistent
percentages of employees' pensionable pay as recommended by independent
qualified actuaries. Under US GAAP, the projected benefit obligation (pension
liability) in respect of the Group's defined benefit plans would be matched
against the fair value of the plans' assets and would be adjusted to reflect any
unrecognized obligations or assets in determining the pension cost or credit for
the year.

There are no material differences in pension costs resulting from the
application of US GAAP.

      ACCOUNTING PRINCIPLES (continued)

CONSOLIDATED STATEMENT OF CASH FLOWS

The consolidated statements of cash flows prepared under UK GAAP present
substantially the same information as those required under US GAAP but they
differ, however, with regard to classification of items within them and as
regards the definition of cash and cash equivalents.

Under UK GAAP, cash is defined as cash in hand and deposits repayable on demand
less overdrafts repayable on demand. Under US GAAP, cash and cash equivalents
would not include bank overdrafts but would include cash deposits repayable
within three months. Under UK GAAP, cash flows are presented separately for
operating activities, returns on investments and servicing of finance, taxation,
capital expenditure and financial investment, acquisitions, equity dividends,
management of liquid resources and financing. US GAAP, however, requires only
three categories of cash flow activity to be reported: operating, investing and
financing. Cash flows from taxation and returns on investments and servicing of
finance shown under UK GAAP would be included as operating activities under US
GAAP. The payment of dividends would be included as a financing activity under
US GAAP. Under US GAAP, capital expenditure and financial investment and
acquisitions would be reported within investing activities.

The categories of cash flow activity under US GAAP can be summarized as follows:

         UNAUDITED PRO FORMA CONDENSED AND COMBINED FINANCIAL STATEMENTS


         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 in Item 5
above 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 the 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 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


                                       43

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.

(b)          Adjustment to eliminate assets not acquired and liabilities not
             assumed by Aavid.

(c)          Adjustment to record inventory at fair value.

(d)          Represents non-recurring $3,049 charge resulting from the write-up
             of inventory to fair value that occurred during purchase accounting
             for the Thermalloy Division's opening balance sheet. Actual cost of
             sales in the 12 months following the acquisition will reflect this
             additional charge. This amount has not been reflected in the pro
             forma statements of income.

(e)          Adjustment to record fixed assets at fair value.

(f)          Adjustment to record the goodwill resulting from the acquisition of
             the Thermalloy Division and an additional 20.2% of Curamik. The
             goodwill is calculated as follows:

(g)          Adjustment to record $1,650 in deferred financing fees related to
             additional borrowings discussed in (a) above.

(h)          Adjustment to record an asset of $5,889 related to present value of
             estimated market value rent expense related to the Thermalloy
             Division's 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 and related amortization of $1,039 for the year ended
             December 31, 1998 and $759 for the nine months ended September 30,
             1999, arising from their prior acquisitions.

(j)          Adjustment to record accrued liabilities related to severance costs
             associated with the closure of certain offices and operations of
             the Thermalloy Division, which is estimated to be $575. This
             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 (g) 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.

(q)      Adjustments to interest expense resulting from the elimination of
         interest expense associated with Thermalloy Division's borrowings,
         additional interest and amortization of deferred financing costs
         associated with our additional borrowings used to fund the acquisitions
         of the Thermalloy Division and additional Curamik shares as follows:

(r)          Adjustment to record the adjustment to the income tax provision
             related to pro forma adjustments after considering the impact of
             non-deductible goodwill.


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 duplicative corporate functions.
             These cost savings are expected to be as follows:

Cost savings from elimination of duplicative
  selling, general and administrative functions          3,124                2,299
                                                        ------               ------
Total cost savings                                      $4,656               $3,297
                                                        ======               ======
</TABLE>


         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.
