subsidiary of Buyer instead of the purchasing entity described in Section 1.1
hereto in order to effect the purposes of this Agreement. Company and Seller
shall take all action necessary and appropriate to effect, or cause to be

(i) adversely affect the timing of the consummation of the transactions
contemplated by this Agreement or (ii) adversely affect the tax effect or
economic benefits of the transactions contemplated by this Agreement or (iii)
modify, in any respect, or otherwise release Buyer from performing, any covenant

provides a reasonable indication that the item applies to another Schedule
contained in the Disclosure Schedule. For purposes of this Agreement, the term
"KNOWLEDGE OF SELLER" means the actual knowledge of the individuals listed on

         to conduct business and is in good standing under the laws of each
         jurisdiction where such qualification is required, except where the
         lack of such qualification would not have a material adverse effect (x)
         on the business, operations, results of operations, assets, liabilities
         or financial condition of the Company and the Company's Subsidiaries
         taken as a whole (other than any such change, effect, event or
         condition that arises from changes in general economic conditions or
         conditions affecting the Company and its Subsidiaries' industry
         generally, or such changes, effects, events or conditions resulting
         from the announcement or the consummation of the transactions
         contemplated hereby), or (y) on the ability of Seller or the Company to
         consummate the transactions contemplated by this Agreement or perform
         its respective obligations hereunder (in either event, a "MATERIAL
         ADVERSE EFFECT"). The Company and each of its Subsidiaries has full

         operation of the tower top business.

         2.3   CAPITALIZATION.  The entire authorized capital stock of the
Company consists of 2,450 Company Shares, all of which are issued and

limitations of any kind

<Page>

options, warrants, purchase rights, subscription rights, conversion rights,
exchange rights, or other contracts or commitments that could require the
Company to issue, sell or otherwise cause to become outstanding any of its
capital stock. There are no outstanding or authorized stock appreciation,
phantom stock, profit participation or similar rights with respect to the
Company.

         2.4   AUTHORIZATION OF TRANSACTION. Seller and the Company each have
the requisite corporate power and authority to execute, deliver and perform its
respective obligations under this Agreement. The execution, delivery and
performance of this Agreement by Seller and the Company and the consummation of
the transactions contemplated hereby have been duly and validly authorized by
all requisite corporate action, and no other corporate proceedings on each of
its respective parts are necessary to authorize the execution, delivery and
performance of this Agreement. This Agreement has been duly executed and
delivered by Seller and the Company and assuming the due authorization,
execution and delivery hereof by Buyer, constitutes the valid and binding
obligation of each of Seller and the Company, enforceable in accordance with its
terms, except as such enforcement may be limited by applicable bankruptcy,

affecting enforcement of creditors' rights or by general principles of equity.

         2.5   NONCONTRAVENTION AND CONSENTS.

               (a) Neither the execution and the delivery of this Agreement, nor
         the consummation of the transactions contemplated hereby, will (i)
         violate any constitution, statute, regulation, rule, injunction,
         judgment, order, decree, ruling, charge or other restriction of any
         federal, state, local or foreign entity exercising executive,
         legislative, judicial, regulatory or administrative functions of or
         pertaining to government (each, a "GOVERNMENT ENTITY") to which Seller,
         the Company or any of the Company's Subsidiaries are subject or any
         provision of the articles of incorporation or bylaws (or similar
         charter documents) of Seller, the Company or any of the Company's
         Subsidiaries or (ii) except as set forth in Section 2.5(a) of the
         Disclosure Schedule, violate, conflict with, result in a breach of,

         other arrangement to which any of Seller, the Company or any Subsidiary
         of the Company is a party or by which it is bound or to which any of
         the assets of the Company and its Subsidiaries are subject (or result
         in the imposition of any Security Interest upon any of such assets),
         except where the violation, conflict, breach, default, acceleration,
         termination, modification, cancellation or failure to give notice would
         not have a Material Adverse Effect.

               (b) Except for filings required under the Finnish Act on
         Competition Restrictions, filings required under the Hart-Scott-Rodino
         Antitrust Improvements Act of 1976, as amended (the "HART-SCOTT-RODINO
         ACT") or as set forth in the Disclosure Schedule, none of Seller, the
         Company or any of the Company's Subsidiaries needs to give any notice
         to, make any filing with, or obtain any authorization, consent, or
         approval of any Governmental Entity in order for Seller and the Company
         to consummate the transactions contemplated by this Agreement, except
         where the failure to give notice, to

<Page>

         file, or to obtain any authorization, consent, or approval would not
         reasonably be expected to have a Material Adverse Effect.

         2.6   TANGIBLE PERSONAL PROPERTY. The Company and its Subsidiaries
after consummation of the transactions contemplated by Section 6.5 hereof) have,
on a consolidated basis, good and marketable title to, or a valid leasehold
interest in, all of the material tangible personal property sufficient for the
conduct of the Business as presently conducted, except where failure to have
good and marketable title or a valid leasehold interest would not have a
Material Adverse Effect. All such tangible personal property is in good working
order and condition, ordinary wear and tear excepted, except where the failure
to so maintain such assets would not have a Material Adverse Effect.

         2.7   SUBSIDIARIES. Neither the Company nor any of its Subsidiaries
owns, controls or holds with the power to vote, directly or indirectly, of
record, beneficially or otherwise, any share capital, capital stock or any
equity or ownership interest in any company, corporation, partnership,
association, joint venture, business, trust or other entity (each a
"SUBSIDIARY"), except for the Subsidiaries listed in the Disclosure Schedule,
and except for ownership of securities in any publicly traded company held for
investment by the Company or any of its Subsidiaries and comprising less than
five percent of the outstanding stock of such company. The Company is directly
or indirectly the registered, record and beneficial owner of all of the
outstanding share capital or shares of capital stock (or other ownership
interests) of each of its Subsidiaries, there are no proxies with respect to
such shares, and no securities of any of such Subsidiaries are or may be
required to be issued by reason of any options, warrants, scrip, rights to

shares of any capital stock (or other ownership interests) of any such
Subsidiary, and there are no contracts, commitments, understandings or
arrangements by which the Company or any such Subsidiary is bound to issue,
transfer or sell any share capital or shares of such capital stock or securities
convertible into or exchangeable for such shares (or other ownership interests).
All of such shares (or other ownership interests) so directly or indirectly
owned by the Company are validly issued, fully paid and nonassessable and are
owned by it free and clear of any Security Interests with respect thereto.

         2.8   FINANCIAL STATEMENTS.

               (a) Seller has delivered to Buyer copies of the following
         financial statements (collectively, the "FINANCIAL STATEMENTS"): (i)
         audited consolidated balance sheets as of October 31, 1999 and October
         31, 2000 and statements of income, statements of cash flow for the
         three fiscal years ended October 31, 2000 for the operations of the
         Company and its Subsidiaries located in Finland and the notes thereto
         (including the operations of the tower top business)(the "AUDITED
         FINANCIAL STATEMENTS"); and (ii) unaudited consolidated balance sheet
         and statement of income (the "FILTER FINANCIAL STATEMENTS") as of and
         for the ten months ended August 30, 2001 (the "MOST RECENT FISCAL
         PERIOD"), for the operations of the Company and its Subsidiaries
         excluding the operation of the tower top business. The Audited
         Financial Statements (including the notes thereto) have been prepared
         in accordance with Finnish generally accepted accounting principles
         ("GAAP") applied on a consistent basis throughout the periods covered
         thereby (except as may be

<Page>

         otherwise indicated in the notes thereto) and present fairly, in all
         material respects, the financial condition of the operations of the
         Company and its Subsidiaries as of such dates and the results of
         operations of the Company and its Subsidiaries located in Finland for
         such periods. The Filter Financial Statements have been prepared in
         accordance with U.S. GAAP applied on a consistent basis throughout the
         periods covered thereby (except as may be otherwise indicated in the
         notes thereto) and present fairly, in all material respects, the
         financial condition and results of operations of the Company and its
         Subsidiaries, excluding the operation of the tower top business, as of
         such dates and for such periods; PROVIDED, HOWEVER, that the Filter
         Financial Statements are subject to normal year end adjustments and
         lack of footnotes or other presentation items; and PROVIDED, THAT, the
         Filter Financial Statements reflect intercompany allocations of
         overhead and other non-specific expenses between the wireless filter
         business and the operation of the tower top business which Seller
         believes are reasonable, based upon the historical practices and
         operations of the Company and its Subsidiaries, as of the dates of such
         financial statements.

               (b) Since the end of the Most Recent Fiscal Period, the Company
         and its Subsidiaries have not incurred any liabilities or obligations
         that are required to be disclosed under GAAP, on the face of the
         applicable Financial Statements, except (i) as set forth in the
         Disclosure Schedule, (ii) the liabilities recorded on the Filter
         Financial Statements (including the notes thereto), or (iii)
         liabilities or obligations incurred since the end of the Most Recent
         Fiscal Period (whether or not incurred in the ordinary course of
         business) that would not reasonably be expected to have a Material
         Adverse Effect.

               (c) All accounts and notes receivable reflected in the Filter
         Financial Statements and all accounts receivable insofar as it
         represents sales of products relating to the filter business arising
         after the end of the Most Recent Fiscal Period (collectively the
         "ACCOUNTS RECEIVABLE") have arisen in the ordinary course of business
         and represent valid obligations of nonaffiliated third parties.

         2.9   EVENTS SUBSEQUENT TO MOST RECENT FISCAL PERIOD. Since the end of
the Most Recent Fiscal Period, there has not been any Material Adverse Effect.
Without limiting the generality of the foregoing, since that date the business
and operations of the Company and its Subsidiaries have been conducted only in
the ordinary and usual course and in a manner consistent with past practice, and
have not taken any of the actions set forth in Section 4.2 hereof except as set
forth in the Disclosure Schedule.

         2.10  LEGAL COMPLIANCE. Each of the Company and its Subsidiaries has
complied with all applicable laws (including rules, regulations, codes, plans,
injunctions, judgments, orders, decrees, rulings and charges thereunder)
("LAWS") of Governmental Entities, except where the failure to comply would not
have a Material Adverse Effect. Neither the Company nor its Subsidiaries has
received any written notice, or to the Knowledge of Seller, any other
communication, from any Governmental Entity of any violation of any material Law
and, to the Knowledge of Seller, no such notice or other communication is
threatened. Neither the Company nor its Subsidiaries are in violation of any of
the provisions of their respective articles of incorporation or bylaws or
equivalent organizational documents. The Company and its Subsidiaries have all
requisite licenses, permits, certificates, authorizations and approvals,

<Page>

including health and safety and employee permits, from foreign, federal, state
and local authorities necessary to conduct the Business as currently conducted,
except where any failure to have such Permits will not, individually or in the
aggregate, have a Material Adverse Effect (collectively, the "PERMITS"). All of
the Permits are in full force and effect, and to the Knowledge of Seller, none
of the Company nor the Company's Subsidiaries is in default under any of such
Permits and no event has occurred and no condition exists which, with the giving
of notice, the passage of time, or both, would constitute a default thereunder.
No action or claim is pending or, to the Knowledge of Seller, threatened, to
revoke or terminate any Permit.

         2.11  TAX MATTERS.

               (a) Each of the Company and its Subsidiaries has timely filed all
         returns, declarations, reports, information returns or statements
         ("COMPANY RETURNS") required to be filed in respect of Taxes (as
         defined in subsection (i) below), and has timely paid when due all
         Taxes shown thereon as owing. All such Company Returns were correct and
         complete in all material respects. All Company Returns for periods
         ending on or after January 1, 1998, and all correspondence with Tax
         authorities for such periods have been made available to Buyer.

               (b) There are no liens for Taxes upon any of the assets of the
         Company and its Subsidiaries, other than liens for Taxes not yet due
         and payable or for Taxes that Seller, the Company or any Subsidiary of
         the Company is contesting in good faith through appropriate proceedings
         and for which there is a specific reserve in the applicable Financial
         Statements.

               (c) The unpaid Taxes of the Company and its Subsidiaries (i) did
         not as of the Most Recent Fiscal Period, exceed the reserve for
         liability for Taxes set forth in the unaudited balance sheet for the
         end of the Most Recent Fiscal Period and (ii) will not exceed that
         reserve as adjusted for operations and transactions through the Closing
         Date.

               (d) No deficiencies for any Taxes have been proposed, asserted or
         assessed either orally or in writing against or in respect of the
         Company or its Subsidiaries. All assessments for Taxes with respect to
         the Company and its Subsidiaries with respect to completed and settled
         examinations or concluded litigation have been paid. The Company and
         its Subsidiaries have not incurred a Tax liability from the date of the
         Filter Financial Statements other than a Tax liability in the ordinary
         course of business.

               (e) The Company and the Company's Subsidiaries have not
         requested, or been granted any waiver of any federal, state, local or
         foreign statute of limitations with respect to, or any extension of a
         period for the assessment of, any Tax. No extension or waiver of time
         within which to file any Tax Return of, or applicable to the Company
         and the Company's Subsidiaries has been granted or requested, which
         extension or waiver has not since expired. Neither the Company nor the
         Company's Subsidiaries have granted any power of attorney relating to
         Taxes that will survive the Closing.

               (f) Neither the Company nor any Subsidiary of the Company has any
         liability for unpaid Taxes because it is or once was a member of an
         affiliated, consolidated,

<Page>

         combined or unitary group, and none of the Company nor any Subsidiary
         of the Company is a party to any Tax allocation or sharing agreement or
         liable for the Taxes of any party, as transferee or successor, by
         contract, or otherwise.

               (g) No unsatisfied deficiency, delinquency or default for any Tax
         has been claimed, proposed or assessed against or with respect to the
         Company or any of the Company's Subsidiaries, nor has the Company nor
         any Subsidiary of the Company received notice of any such deficiency,
         delinquency or default which, in any such case, may have a Material
         Adverse Effect.

               (h) Each of the Company and each Subsidiary of the Company have
         complied with all applicable Laws relating to the payment and
         withholding of Taxes (including, without limitation, withholding of
         Taxes pursuant to Chapter 3 or Chapter 24 of the Code or similar
         provisions under any non-U.S. Laws) and has, within the time and in the
         manner required by Law, withheld from employee wages and paid over to
         the proper Governmental Entities all amounts required to be so withheld
         and paid over under all applicable Laws.

               (i) For purposes of this Agreement, "TAX" or "TAXES" means any
         United States, Finnish or other non-U.S. federal, state, provincial or
         local income, alternative minimum, accumulated earnings, personal

         Company or any Subsidiary of the Company ("OWNED REAL PROPERTY"), (ii)

         for Taxes not yet due and payable or for Taxes that Seller, the
         Company, or any Subsidiary of the Company is contesting in good faith
         through appropriate proceedings, (C) any minor imperfection of title or
         similar immaterial lien that individually or in the aggregate would not
         affect the Company's or its Subsidiaries' ability to conduct the

         Environmental Law, except for such violations as would not result in a
         Material Adverse Effect.

         subject to any, and to the Knowledge of Seller, there is no imminent

                                OTHER AGREEMENTS

         5.1   GENERAL.  In case at any time after the Closing any further
         action is necessary or desirable to carry out the purposes of this
         Agreement, each of the parties will take such further action (including
         the execution and delivery of such further instruments and documents)
         as the other party reasonably may request, all at the sole cost and
         expense of the requesting party (unless the requesting party is

               (a) For the purpose of this Section 5.2, the term "EMPLOYEE"
         shall mean and refer to each individual who has an employer/employee
         relationship with the Company or any of its Subsidiaries in Finland on
         the Closing Date unless a contrary intention shall be herein expressed.

         except as otherwise disclosed in the Disclosure Schedule or arising as
         a result of the transactions contemplated by Section 4.6 hereof, the
         consummation of the transaction contemplated hereby does not affect the
         rights and obligations of the Employees to the Company or any
         Subsidiary of the Company, or the rights and obligations of the Company
         or any Subsidiary of the Company to the Employees, nor does the entry
         into this Agreement or the consummation of the transaction contemplated
         hereby create any obligations for Seller or Buyer to the Employees and
         that (ii) as of the Closing Date, the Company and each Subsidiary of
         the Company shall cease to be a participating employer of and shall
         cease making contributions or otherwise providing benefits under all
         compensation and benefit programs of Seller, including, but not limited
         to, Seller's Global Employee Stock Purchase Plan, all Seller incentive
         plans and all Seller stock option programs. The parties hereto shall
         jointly in a form and manner agreed upon inform the Employees of the
         entry into this Agreement.

               (c) This Section 5.2 shall not create any third party beneficiary
         rights nor shall it inure to the benefit of nor shall it be enforceable
         by any employee or any Person representing the interests of employees.

<Page>

                   (i)     Seller shall timely file or cause to be timely filed
               when due (taking into account all extensions properly obtained)
               all Tax Returns that are required to be filed by or with respect
               to the Company and each Subsidiary on or prior to the Closing
               Date and Seller shall remit or cause the Company to remit the
               Taxes due in respect of such Tax Returns. Buyer shall timely file
               or cause to be timely filed when due (taking into account all
               extensions properly obtained) all Tax Returns that are required
               to be filed by or with respect to the Company and each Subsidiary
               after the Closing Date and Buyer shall remit or cause to be
               remitted any Taxes due in respect of such Tax Returns subject to
               the following sentences of this Section 5.3(a)(i). With respect
               to Tax Returns to be filed by Buyer pursuant to the preceding
               sentence that relate to taxable years or periods or a portion
               thereof ending on or before the Closing Date (x) such Tax Returns
               shall be filed in a manner consistent with past practice and no
               position shall be taken, election made or method adopted that is
               inconsistent with positions taken, elections made or methods used
               in prior periods in filing such Tax Returns (including, without
               limitation, a position which would have the effect of
               accelerating income to periods for which Seller is liable or
               deferring deductions to periods for which Buyer is liable) and
               such Tax Returns shall be submitted to Seller not later than
               thirty (30) days prior to the due date for filing such Tax
               Returns (or, if such due date is within forty-five (45) days
               following the Closing Date, as promptly as practicable following
               the Closing Date) for review and approval by the Seller, which
               approval shall be granted unless such Tax Returns are
               inconsistent with this Section 5.3(a), shall be deemed granted if
               Seller has not objected within ten (10) business days and, in any
               event shall not be unreasonably withheld or delayed, and (y) in
               no event shall Buyer be responsible for a greater amount of Taxes
               with respect to activity occurring prior to the Closing Date than
               had been accrued on the Closing Date Balance Sheet. In the event
               that the Taxes with respect to activity occurring prior to the
               Closing Date are less than the reserve for Taxes included in the
               Closing Date Balance Sheet, Buyer shall promptly remit to Seller,
               by wire transfer of immediately available funds, cash in an
               amount equal to the amount of such reserve less the amount of
               such Taxes.

                   (ii)    None of Buyer or any affiliate of Buyer shall (or
               shall cause or permit the Company or any of its Subsidiaries to)
               amend, refile or otherwise modify (or grant an extension of any
               statute of limitation with respect to) any Tax Return relating in
               whole or in part to the Company or any of its Subsidiaries with
               respect to any taxable year or period ending on or before the
               Closing Date or make or rescind (or permit to be made or
               rescinded) at or after the Closing any express or deemed election
               or take any other action relating to Taxes of the Company or its
               Subsidiaries (other than the Section 338 Election described in
               clause (iii) below) that will increase the Tax liability of
               Seller or (for taxable periods ending on, before or including the
               Closing Date) any Tax liability of the Company or any of its
               Subsidiaries without the prior written consent of Seller, which
               consent may be withheld in the sole discretion of Seller.

                   (iii)   Buyer shall be entitled to make an election under
               Section 338 of the Code, and may make a corresponding election
               under any similar provision of

<Page>

               state or foreign law relating to the purchase of the Company
               Shares in such manner as would cause the transactions
               contemplated by this Agreement to be treated as a purchase or
               sale of assets of the Company or any of its Subsidiaries for Tax
               purposes, but only if such election is made for the Company and
               all of its Subsidiaries (the "SECTION 338 ELECTION").

                   (iv)    Notwithstanding anything herein to the contrary,
               Seller shall not be liable for or pay and shall not indemnify
               Buyer against any Taxes of Buyer, the Company or its Subsidiaries
               that result from any actual or deemed Section 338 Election.

                   (v)     Buyer shall be liable for and shall pay any real
               property transfer or gains tax, stamp tax, stock transfer tax, or
               other similar tax imposed on the sale of the Company Shares
               pursuant to this Agreement, together with any penalties or
               interest with respect to such taxes.

                   (vi)    Seller shall be liable for and shall pay any tax
               imposed on the Company and its Subsidiaries or Buyer (net of any
               tax benefit) relating to the stock options held by employees of
               the Company and its Subsidiaries that were granted by Seller, the
               Company or any Subsidiary of the Company prior to the Closing. In
               the event that, after the Closing, Seller is required to withhold
               any taxes from any employee of the Company or its Subsidiaries,
               relating to stock options granted by Seller, upon the request of
               Seller, the Company shall remit such taxes to the appropriate
               Finnish Tax authority on behalf of Seller or such employee as the
               case may be.

               (b) Cooperation. Seller and Buyer will provide each other with
         such cooperation and information as either of them reasonably may
         request of the other in filing any Tax Return, determining a liability
         for Taxes or a right to a refund of Taxes or in conducting any audit or
         proceeding in respect of Taxes. Such cooperation and information shall
         include providing to Buyer or Seller copies of relevant Tax Returns or
         portions thereof, together with accompanying schedules and related work
         papers and documents relating to rulings or other determinations by
         Taxing authorities and the originals of such documents where available
         to Seller or Buyer, as the case may be, and reasonably requested by the
         other (provided, that the non-requesting party may maintain copies of
         such originals). Each party shall make its employees available on a
         mutually convenient basis to provide explanation of any documents or
         information provided hereunder. Seller or Buyer, upon written request
         by the other, will provide such factual information reasonably
         necessary for filing Tax Returns, Tax planning and contesting any Tax
         audit that Buyer or Seller, as the case may be, possesses as the
         requesting party may reasonably request with respect to the Company.

               (c) Definitions. For purposes of the Agreement,"TAX RETURN" means
         any return, report or similar statement required to be filed with
         respect to any Tax (including any attached schedules), including,
         without limitation, any information return, claim for refund, amended
         return or declaration of estimated Tax.

               (d) Notwithstanding the foregoing, Buyer and Seller agree to
         allocate $49,850,000 of the Purchase Price to the Company Shares and
         $250,000 of the Purchase Price to Seller's agreement not to compete.

               (e) Neither Seller nor Buyer nor any of their respective
         affiliates or representatives shall take any position on any Tax Return
         or with any taxing authority or in any judicial proceeding that is
         inconsistent with Section 5.3 (d). Buyer and Seller each agree to
         timely notify the other party, and to timely provide such other party
         with assistance, in the event of an examination, audit or other
         proceeding regarding the allocation set forth in Section 5.3(d).

         5.4   RETIRING DIRECTORS.  At the next annual general meeting of the
Company, Buyer shall take any and all action necessary to provide that those
directors and managing directors of the Company and its Subsidiaries who have
resigned or been replaced in connection with this transaction are granted
discharge from liability for their management and administration until the
Closing Date (or earlier date of their resignation or replacement); provided,
however, that the auditors of the Company in their reports for the relevant
period do not recommend against such discharge.

         5.5   INTELLECTUAL PROPERTY.  Buyer acknowledges and agrees that the
patents set forth in Schedule 5.5.1 shall be maintained by Seller. Seller
acknowledges and agrees that the patents set forth in Schedule 5.5.2 shall be
maintained by ADC Telecommunications Oy, a Subsidiary of the Company.

         5.6   AGREEMENT NOT TO COMPETE.

               (a) For a period of five (5) years from and after the Closing
         Date, neither Seller nor any of its majority-owned Subsidiaries will,
         other than in the performance of Seller's obligations under this
         Agreement and the License Agreement, directly or indirectly (i)
         manufacture or design for third Persons, distribute, sell, offer for
         sale or promote products that directly and materially compete with
         products within the Solitra Exclusive Field of Use (as defined in the
         License Agreement) (the "PROTECTED BUSINESS"), or (ii) own, manage,
         operate, join, control, or participate in the ownership, management,
         operation or control of, any Person who or which at any relevant time
         during such period is engaged in any business directly and materially
         competing with the Protected Business. Nothing in this Section 5.6
         shall prohibit Seller or any of its Subsidiaries from manufacturing,
         distributing, designing, selling, offering or promoting any products
         that may be used in more than one application (even if one of such
         applications is within the Protected Business) so long as such
         activities are not directed by Seller, whether by design of the product
         or marketing efforts, at the Solitra Exclusive Field of Use (as defined
         in the License Agreement). Nothing contained herein shall prevent
         Seller or any of its affiliates from owning securities in any entity
         that may be engaged in the Protected Business, but only to the extent
         Seller and its affiliates, collectively, do not own, of record or
         beneficially, more than (x) 5% of the outstanding beneficial ownership
         of any publicly traded corporation or (y) fifteen percent (15%) of the
         outstanding beneficial ownership of any other entity.

<Page>

               (b) Nothing in this Agreement is to be construed as limiting (x)
         Seller's or its Subsidiaries' ability to conduct, or requiring Seller
         or its Subsidiaries to alter the manner in which they conduct, any
         business existing prior to the Closing other than the Protected
         Business or (y) continued ownership by Seller or any of its affiliates
         of outstanding securities of any entity owned by Seller or such
         affiliate as of the Closing Date. Buyer acknowledges that Seller and
         its affiliates will be providing services to, and selling products to,
         customers of the Protected Business. Further, notwithstanding anything
         in this Agreement to the contrary, Seller or any of its affiliates may
         acquire an entity that engages in activities that would otherwise be
         prohibited by this Section 5.6 (a "COMPETITIVE BUSINESS") if (i) at the
         time of such acquisition, the aggregate sales attributable to the
         Competitive Business of such entity as reflected in the most recently
         completed fiscal year of the entity to be acquired for which financial
         statements are then available are less than the greater of $25,000,000
         or 25% of the total sales of such entity for such fiscal year and (ii)
         Seller, or its affiliates, as the case may be, ceases to engage in such
         Competitive Business within one (1) year after the consummation of the
         transaction or as soon as practicable thereafter. Finally, in the event
         all of the capital stock of Seller is acquired by a third party, the
         provisions of this Section 5.6 shall not apply to the acquirer (but the
         provisions shall continue with respect to Seller and its Subsidiaries).

               (c) For a period commencing upon expiration of the term of the
         Transition Manufacturing Agreement and ending five (5) years from and
         after the Closing Date, neither Seller nor any of its majority-owned
         Subsidiaries will operate a manufacturing plant for the production of
         tower top products in the country of Finland; PROVIDED, HOWEVER, that
         Seller and its majority-owned Subsidiaries shall not be prohibited from
         operating any facility which designs tower top products (such design
         facilities being allowed to make proto-types of products) in the
         country of Finland or otherwise employing engineers in connection with
         the tower top business in the country of Finland.

               (d) For a period of two (2) years from the Closing Date, none of
         Seller or any of Seller's majority-owned Subsidiaries may recruit,
         solicit or induce, or attempt to recruit, solicit or induce, or cause
         any third party to recruit, solicit or induce, or attempt to recruit,
         solicit or induce, any employee or employees of the Company or any of
         its Subsidiaries to terminate their employment with, or otherwise cease
         their relationship with the Company or such Subsidiary. Further, for a
         period of two (2) years from the Closing Date, none of Seller or any of
         Seller's majority-owned Subsidiaries may hire or cause any third party
         to hire any employee or employees of the Company or any of its
         Subsidiaries. Notwithstanding the foregoing, Seller or any of Seller's
         majority-owned Subsidiaries may solicit the employment of any employee
         of the Company or any Subsidiary of the Company whose employment has
         been terminated by the Company or any Subsidiary of the Company.

               (e) For a period of two (2) years from the Closing Date, none of
         Buyer, any majority-owned Subsidiary of Buyer, the Company or any
         Subsidiary of the Company may recruit, solicit or induce, or attempt to
         recruit, solicit or induce, or cause any third party to recruit,
         solicit or induce, or attempt to recruit, solicit or induce, any
         employee or employees who were transferred to Seller (or a Subsidiary
         of Seller) in connection with the transfer of the TTP Assets (each a
         "TTP EMPLOYEE") to terminate their employment

<Page>

         with, or otherwise cease their relationship with Seller or such
         Subsidiary. Further, for a period of two (2) years from the Closing
         Date, none of Buyer, any majority-owned Subsidiary of Buyer, the
         Company or any Subsidiary of the Company may hire or cause any third
         party to hire any TTP Employee. Notwithstanding the foregoing, Buyer,
         any majority-owned Subsidiary of Buyer, the Company or any Subsidiary
         of the Company may solicit the employment of any TTP Employee whose
         employment has been terminated by Seller or any Subsidiary of Seller
         or, with respect only to TTP Employees engaging in manufacturing
         activities, who decline Seller's offer of continued employment in a
         Seller manufacturing facility located outside of the City of Oulu,
         Finland.

               (f) If Buyer or the Company stops offering products within the
         Protected Business within the five (5) year period provided in this
         Section 5.6, the provisions of this Section 5.6 shall terminate
         immediately.

               (g) In the event a party shall violate any legally enforceable
         provision of this Section 5.6 as to which there is a specific time
         period during which such party is prohibited from taking certain
         actions or from engaging in certain activities, as set forth in this
         Section 5.6, then, in such event, such violation shall toll the running
         of such time period from the date of such violation until such
         violation shall cease.

         5.7   PRE-CLOSING ACCESS. Buyer understands that Seller is currently in
discussions with Nokia with respect to a proposal to re-price the "Cowboy
Program," which discussions may be completed prior to Closing. During the period
commencing immediately after the date of this Agreement until the earlier to
occur of the Closing or the termination of this Agreement (pursuant to Article
IX hereof), Seller, the Company and the Company's Subsidiaries will permit
representatives of Buyer reasonable access to the Company's premises related to
the filter business and to reasonably observe activities relating to the
maintenance of major customer relations with the filter business so as to
prepare for the transition of these relationships pending the Closing and Buyer
shall use its good faith efforts not to disrupt the operation of the business of
the Company and its Subsidiaries in the ordinary course. Specifically, Seller
will permit Buyer (i) subject to receipt of any necessary consent from Nokia
(which Seller will use its commercially reasonable efforts to obtain promptly)
to provide input to the Company and its Subsidiaries and review with the
Company's and its Subsidiaries' their cost reduction roadmaps for Nokia on
current products related to the filter business; (ii) to review with the Company
and its Subsidiaries any significant contractual commitments for the filter
business made after the date hereof and prior to Closing or the termination of
this Agreement (pursuant to Article IX hereof), including material bids and
proposals (other than purchase orders for products received in the ordinary
course of business); and (iii) to review with the Company and its Subsidiaries
all new material business opportunities for the filter business and all material
commitments of resources to such business opportunities.

         5.8   FINANCIAL STATEMENT MATTERS. Seller agrees that it shall bear any
and all fees and expenses of Seller's independent accountants incurred in
connection with the preparation of audited financial statements pursuant to
Section 6.15 hereof.

         8.1 INDEMNIFICATION BY SELLER.  Seller shall indemnify and defend Buyer
from and against any and all losses,  liabilities,  damages,  costs and expenses
(including reasonable attorneys' fees) (collectively,  "LOSSES"), arising out of
or based upon:

               (a) any misrepresentation in or breach of any representation or
         warranty of Seller set forth in this Agreement, the Disclosure Schedule
         or any closing certificate delivered to Buyer pursuant to this
         Agreement;

<Page>

               (b) any nonfulfillment in any material respect of any covenant,
         agreement or other obligation of Seller or (in respect of matters prior
         to Closing) the Company, in each case as set forth in this Agreement;

               (c) any third party claim for products liability relating to
         inherent defects of any products of the Company or its Subsidiaries
         which have been manufactured and/or sold prior to the Closing, other
         than claims as reserved in the appropriate financial statements of the

               (d) with respect to Section 4.6 of this Agreement, (x) any

         in all cases the amount of indemnification due shall be subject to
         deduction for the amount of the Remaining Funds.

         8.2   INDEMNIFICATION BY BUYER. Buyer shall indemnify and defend Seller
from and against any and all Losses arising out of, based upon or relating to:

               (a) any misrepresentation in or breach of any representation or
         warranty of Buyer set forth in this Agreement, the Disclosure Schedule
         or closing certificate delivered to Seller pursuant to this Agreement;
         and

               (b) any nonfulfillment in any material respect of any covenant,
         agreement or other obligation of Buyer or (in respect of matters after
         the Closing) the Company, in each case as set forth in this Agreement.

         8.3   THIRD PARTY CLAIMS.

               (a) If any third party shall notify either party (the
         "INDEMNIFIED PARTY"), with respect to any matter (a "THIRD PARTY
         CLAIM") which may give rise to a claim for indemnification against the
         other party (the "INDEMNIFYING PARTY") under this Article VIII, then
         the Indemnified Party shall promptly (and in any event within fifteen
         (15) business days after receiving notice of the Third Party Claim)
         notify the Indemnifying Party thereof in writing; provided, however,
         that no delay on the part of the Indemnified Party in notifying the
         Indemnifying Party shall relieve the Indemnifying Party from any
         obligation under this Agreement except to the extent the Indemnifying
         Party thereby is prejudiced.

               (b) The Indemnifying Party shall have the right to assume and
         control the defense of the Third Party Claim with counsel of its own
         choice reasonably satisfactory to the Indemnified Party so long as the
         Indemnifying Party notifies the Indemnified Party of such defense in
         writing within twenty (20) days after the Indemnified Party has given
         notice of the Third Party Claim; provided, however, that the
         Indemnified Party may retain separate co-counsel at its sole cost and
         expense and participate in the defense of the Third Party Claim.

               (c) So long as the Indemnifying Party has assumed and is
         conducting the defense of the Third Party Claim in accordance with
         Section 8.3(b), (i) the Indemnifying

<Page>

         Party shall not consent to the entry of any judgment or enter into any
         settlement with respect to the Third Party Claim without the prior
         written consent of the Indemnified Party (which consent shall not to be
         unreasonably withheld or delayed) unless the judgment or proposed
         settlement involves only the payment of money damages by the
         Indemnifying Party and does not impose an injunction or other equitable
         relief upon the Indemnified Party and (ii) the Indemnified Party shall
         not consent to the entry of any judgment or enter into any settlement
         with respect to the Third Party Claim without the prior written consent
         of the Indemnifying Party (which consent shall not to be unreasonably
         withheld or delayed).

               (d) In the event the Indemnifying Party does not assume and
         conduct the defense of the Third Party Claims in accordance with
         Section 8.3(b), the Indemnified Party may defend against, and consent
         to the entry of any judgment or enter into any settlement with respect
         to, the Third Party Claim in any manner it reasonably deems appropriate
         (and the Indemnified Party need not consult with or obtain any consent
         from the Indemnifying Party in connection therewith).

         8.4   SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The representations
and warranties of each party contained in this Agreement shall survive the
Closing Date for a period of twelve (12) months, except that (a) claims under
Section 8.1(c) of this Agreement shall survive the Closing Date for a period of
eighteen (18) months, and (b) claims which arise out of or relate to the matters
set forth in Sections 2.11 (Tax Matters) and 2.17 (Environmental) hereof shall
survive for the full period of the applicable statute of limitations. Any claim
for indemnity under Sections 8.1 or 8.2 hereof shall be asserted in writing,
setting forth in reasonable detail the identity, nature and amount of losses and
delivered to the party providing indemnification promptly after the occurrence
of such Loss, but in any event prior to the expiration of the applicable
survival period.

         8.5   INDEMNIFICATION LIMITATIONS. Other than in respect of claims
which arise out of or relate to the matters set forth in Section 1.2(b)
(Purchase Price Adjustment), Section 2.11 (Tax Matters), Section 5.3 (Tax
Matters) or Section 8.1(d) (Transfer of TTP Assets) hereof or which are listed
on Schedule 8.5 which shall not be subject to any minimum aggregate amount of
claim, Buyer may not assert any claim for Losses under Section 8.1 hereof until
the aggregate amount of such claims under this Agreement exceed $750,000, and
then Buyer may only assert claims for the excess of such claims over $750,000
(the "BASKET"). The aggregate liability of Seller for all claims of Losses under
Section 8.1 shall not exceed 15% of the Purchase Price; provided, that such
limit does not apply in the event of an intentional or fraudulent
misrepresentation or Losses arising out of or relating to Sections 2.11 (Tax
Matters) and 5.3 (Tax Matters). Notwithstanding any provision herein to the
contrary, Seller shall not have any indemnification obligation hereunder arising
in connection with the matters set forth in Section 2.8(b)(l) of the Disclosure
Schedule (including, without limitation, any claim that the Company or its
Subsidiaries did not act, or Seller did not cause the Company or its
Subsidiaries to act, in a commercially reasonable matter to mitigate any losses
or exposure to losses), or for any breach of a representation or warranty of
Seller hereunder to the extent Buyer has actual knowledge of such breach of
representation or warranty, or the specific facts or circumstances giving rise
to such breach, on the Closing Date. Buyer shall not be entitled to make any
claim for a Loss to the extent that a provision or allowance for the Loss has
been made in the applicable Financial Statements or to

<Page>

the extent the Loss is otherwise accounted for or reflected in the applicable
Financial Statements. For purposes of this Agreement, a liability that is
contingent shall not constitute a Loss unless and until such contingent
liability becomes an actual liability and is due and payable; provided, however,
that this sentence shall not preclude a party from asserting its right to
indemnification under this Article VIII prior to the time such contingent
liability becomes an actual liability. All Losses recoverable by an Indemnified
Party under Section 8.1 or 8.2 shall be net of any tax benefits and insurance
proceeds received by the Indemnified Party or the insurance proceeds which would
have been recoverable had the insurance coverage set forth in the Disclosure
Schedule been continued. For purposes of determining the amount of any tax
benefit pursuant to the preceding sentence, the marginal combined federal and
state income tax rate of Buyer shall be deemed to be 40%. All indemnification
payments made under this Article VIII shall be deemed an adjustment to the
Purchase Price unless otherwise required by law.

         8.6   EXCLUSION OF LIABILITIES. Notwithstanding any other provision of
this Agreement, Seller acknowledges and agrees that Seller shall retain and
maintain full liability, obligation and commitment for satisfaction of, and
Buyer, the Company and each of the Company's Subsidiaries shall not have any
liability, obligation or commitment for, any and all liabilities for claims or
losses arising in respect of retention bonuses, change in control payments and
the termination of vested or unvested options or warrants issued to or held by
any employee, officer, director or consultant of or to the Company and its
Subsidiaries in respect of matters or events occurring prior to Closing, and
which were granted by Seller or the Company or any affiliate of the Company
prior to the Closing.

         8.7   EXCLUSIVE REMEDY. Buyer and Seller hereby acknowledge and agree
that, from and after the Closing, their sole remedy with respect to any and all
claims (other than fraud) arising under this Agreement shall be pursuant to this
Article VIII. In furtherance of the foregoing, Buyer and Seller hereby waive,
from and after the Closing, to the fullest extent permitted by law, any and all
other rights, claims and causes of action it may have against the other party
under this Agreement, except for rights, claims and courses of action provided
for in this Article VIII. Buyer and Seller agree that irreparable damage would
occur if any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to any injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions hereof, without the necessity of posting a bond in
connection therewith, this being in addition to any other remedy to which they
are entitled at law or in equity. Notwithstanding the foregoing, nothing herein
shall prevent either Buyer or Seller from bringing an action based upon
allegations of fraud with respect to the other in connection with this Agreement
or any certificate delivered pursuant hereto.

         8.8   LOST PROFITS AND SPECIAL DAMAGES. Notwithstanding any other
provisions of this Agreement to the contrary, neither Seller nor Buyer shall be
required to indemnify or otherwise protect the other party for damage to
reputation, lost business opportunities, lost profits, mental or emotional
distress, incidental, special, exemplary, indirect or consequential damages.

         8.9   NO DOUBLE RECOVERY. To the extent that a Loss occurs and the
amount of such Loss was taken into account in connection with determining any
adjustment to the Purchase Price pursuant to the provisions of Section 1.2(b) of
this Agreement, Seller shall not be required

<Page>

to provide indemnification for the amount of the Loss, and Buyer shall not be
entitled to seek indemnification for such Loss under this Article VIII or to
include such Loss in the Basket under Section 8.5 of this Agreement. To the
extent that a Loss occurs for which Seller provides indemnification to Buyer
under this Article VIII, then Buyer shall not be entitled to take the amount of
such Loss into account in determining the amount of any adjustment to the
Purchase Price pursuant to the provisions of Section 1.2(b) of this Agreement.

                                   ARTICLE IX
                                   TERMINATION

         9.1   TERMINATION OF AGREEMENT.  This Agreement may be terminated at
any time prior to the Closing Date as follows:

               (a) by mutual written consent of Buyer and Seller;

               (b) by Buyer by giving written notice to Seller at any time prior
         to the Closing in the event Seller has materially breached any
         representation, warranty or covenant contained in this Agreement such
         that the conditions specified in Article VI will not be satisfied;

               (c) by Seller by giving written notice to Buyer at any time prior
         to the Closing in the event Buyer has materially breached any
         representation, warranty or covenant contained in this Agreement such
         that the conditions specified in Article VII will not be satisfied; and

               (d) by either Seller or Buyer if (i) the Closing does not occur
         on or prior to the close of business on November 7, 2001; PROVIDED,
         HOWEVER, that the right to terminate this Agreement pursuant to this
         Section 9.1(d)(i) shall not be available to any party whose failure to
         fulfill any of its obligations contained in this Agreement has been the
         cause of, or resulted in, the failure of the Closing to have occurred
         on or prior to the aforesaid date (which proviso shall not be
         applicable with respect to any discretionary right of a party as
         expressly provided in this Agreement); or (ii) any Governmental Entity
         having jurisdiction over a party hereto shall have issued an order,
         decree or ruling or taken any other action permanently enjoining,
         restraining or otherwise prohibiting the transactions contemplated by
         this Agreement and such order, decree, ruling or other action shall
         have become final and nonappealable. Notwithstanding the foregoing,
         each of Seller and Buyer shall take or cause to be taken all
         appropriate and reasonable commercial efforts to achieve a Closing on
         or before October 31, 2001.

         9.2   EFFECT OF TERMINATION. If either party terminates this Agreement
pursuant to Section 9.1 above, all rights and obligations of the parties
hereunder shall terminate without any liability of such party to the other party
(except for any liability of a party then in breach); provided, however, that
the last sentence of Section 4.3 (Confidentiality), and Sections 10.1 (Press
Releases and Public Announcements), 10.8 (Governing Law) and 10.11 (Expenses)
shall survive indefinitely. Buyer and Seller hereby agree that in the event that
either Buyer or Seller terminates this Agreement pursuant to Section 9.1 because
one of the conditions set forth in Article VI in the case of Buyer, or in
Article VII in the case of Seller, has not been satisfied, then

<Page>

the parties shall only disclose that this Agreement has been terminated because
the conditions to Closing have not been satisfied, and shall not disclose either
which condition(s) were not satisfied or the reasons why the condition(s) were
not be satisfied. Nothing in the foregoing sentence shall in any manner prohibit
or restrict disclosure necessary for judicial or arbitral proceedings commenced
by any party with respect to either the enforcement or interpretation of this
Agreement or any party's failure to satisfy any particular condition to close
contained in this Agreement.

                                   ARTICLE X
                                  MISCELLANEOUS

is required by applicable law or any listing or trading agreement concerning its
publicly traded securities (in which case the disclosing party, prior to making
the disclosure, shall, if reasonable under the circumstances, advise the other
