1.3(A) (the "APPLICABLE ACCOUNTING

                                       -3-

STANDARDS"). As used herein "BUSINESS DAY" means any day other than a Saturday,
Sunday or other day on which commercial banks in the City of New York are
authorized by law to close.

     B.   Within ninety (90) days after its receipt of the Closing Balance
Sheet, Purchaser shall cause its accountants to review the Closing Balance Sheet
and the calculation of the Closing Net Worth set forth therein. If Purchaser has
any objection to any such calculations, or to any of the figures shown on the
Closing Balance Sheet, Purchaser shall, within such ninety (90) day period,
inform Sellers in writing thereof (the "PURCHASER'S OBJECTION"), setting forth
in reasonable detail the basis for its objection and the adjustments to the
Closing Net Worth of the Businesses shown in the Closing Balance Sheet which
Purchaser believes should be made, based on the Applicable Accounting Standards.
Sellers shall then have thirty (30) days after their receipt of a Purchaser's
Objection to review and respond to the Purchaser's Objection ("SELLERS' REVIEW
PERIOD"). If Purchaser and Sellers are unable to resolve all of their
disagreements with respect to the determination of the Closing Net Worth of the
Businesses within ten (10) days after the end of the Sellers' Review Period,
they shall refer their remaining disagreements to KPMG (the "ACCOUNTING FIRM"),
who shall determine, on the basis of the standards, principles and methods set
forth on SCHEDULE 1.3(A), and only with respect to the remaining disagreements
submitted to them, whether and to what extent the Closing Net Worth of the
Businesses shown on the Closing Balance Sheet requires adjustment. The Purchaser
and the Sellers shall direct the Accounting Firm to deliver its report and
determination of such adjustments as quickly as reasonably possible. The
Accounting Firm's determination shall be final, conclusive and binding upon
Purchaser and Sellers. The fees and disbursements of the Accounting Firm shall
be shared equally by Purchaser and Sellers. Purchaser and Sellers shall make
readily available to the Accounting Firm all relevant books and records and any
work papers (including those of the parties' respective accountants) relating to
the Financial Statements and the Closing Balance Sheet and all other items
reasonably requested by the Accounting Firm. The "ADJUSTED CLOSING BALANCE
SHEET" shall be (i) the Closing Balance Sheet in the event that (x) no
Purchaser's Objection is delivered to Sellers during the ninety (90) day period
specified above, or (y) Sellers and Purchaser so agree, (ii) the Closing Balance
Sheet, adjusted in accordance with the Purchaser's Objection in the event that
Sellers do not respond to Purchaser's Objection within the Sellers' Review
Period, or (iii) the Closing Balance Sheet, as adjusted by either (x) the
agreement of Sellers and the Purchaser or (y) the Accounting Firm.

     C.   Purchaser shall provide Sellers and their accountants full access to
the books and records of the Businesses, to any other information, including
work papers of its accountants (to the extent available to the Purchaser), and
to any employees to the extent necessary for Sellers to prepare the Closing
Balance Sheet. Purchaser and its accountants shall have full access to all
information used by Sellers in preparing the Closing Balance Sheet, including
the work papers of their accountants (to the extent available to the Sellers).

     D.   Within ten (10) days following issuance of the Adjusted Closing
Balance Sheet, the adjustment payments payable pursuant to this Section 1.3(D)
shall be paid by wire transfer of immediately available funds to a bank account
designated by Purchaser or Sellers, as the case may be. Purchaser or Sellers, as
the case may be, shall make an adjustment payment in an amount equal to the
difference between (x) the Benchmark Net Worth and (y) the Closing Net

                                       -4-

Worth as derived from the Adjusted Closing Balance Sheet, as follows: (1) the
adjustment payment will be made by Sellers to Purchaser to the extent that such
Closing Net Worth is less than the Benchmark Net Worth; and the adjustment
payment will be made by Purchaser to Sellers to the extent that such Closing Net
Worth Sheet is greater than the Benchmark Net Worth; plus, in either case,
interest thereon from the Closing Date through the date of payment at the rate
of interest publicly announced by Citibank, N.A. or any successor thereto in New
York, New York from time to time as its "base rate".

     E.   As used herein, the term "BENCHMARK NET WORTH" means the amount equal
to $21,694,000. The parties agree that the Benchmark Net Worth represents the

calculation is attached hereto as SCHEDULE 1.3(E). As used herein, the term "NET
WORTH" means the aggregate assets of the Businesses, less the Liabilities of the
Businesses, in each case of the types included in the calculation of the
Benchmark Net Worth and calculated in accordance with the Applicable Accounting

proceedings and, to the knowledge of the Sellers, no condemnation proceedings
have been threatened, in each case with respect to any of the Leased Realty, and
no such property has been condemned. No Company or Seller has received notice of
any Legal Proceedings, and, to the knowledge of the Sellers, no Legal
Proceedings have been threatened, that could, with the passage of time or

Realty.

US Assets, P&G plc has legal and beneficial ownership of all of the UK Assets,

          The Assets of the Companies, along with the US Assets, the UK Assets,
German Assets, the UK Lease Sites, the UK Lease Site Leases and the Excluded

they are currently operated.

held or owned by an Affiliate of

the Companies or any Seller and which are to be transferred to the Purchaser or

     K.   EMPLOYEES AND EMPLOYEE BENEFIT PROGRAMS.

           (a)    EMPLOYEES. SCHEDULE 3.1(K) contains a complete and accurate
list of (a) the senior management and other key employees of each US Company and
Autronics US (to the extent devoting a majority of their employment time to the
US Business) as of the date hereof; (b) a list of all senior employees of each
of the UK Companies and the UK Business as of the date hereof and (c) the senior
management and other key employees devoting at least a majority of their working
time to the performance of services for the German Business as of the date
hereof (the ""German P&G EMPLOYEES"").

          (b)     EMPLOYEE BENEFIT PROGRAMS.

                  (i)    P&G CONTROLS US AND AUTRONICS US.

                  (1)    Set forth on SCHEDULE 3.1(K)(b)(i) is a complete and
correct list of (1) each "employee benefit plan" (within the meaning of section
3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")). All such plans are collectively referred to as the "US COMPANY
PLANS."

                  (2)    Each US Company Plan has been established and
administered in accordance with its terms, and in material compliance with the
applicable provisions of ERISA

                                      -17-
<Page>

and the Internal Revenue Code of 1986, as amended (the "CODE"). The terms of
each US Company Plan that is intended to be qualified within the meaning of Code
Section 401(a) have been determined by the Internal Revenue Service to be so
qualified, and neither P&G Controls US nor any of the Sellers is aware of any
event or circumstance that could cause the Internal Revenue Service to
disqualify any US Company Plan that is intended to qualify under section 401(a)
of the Code. With respect to any US Company Plan, no actions, audits,
examinations, suits or claims (other than routine claims for benefits in the
ordinary course) are pending or to Sellers' knowledge threatened. Neither P&G
Controls US nor Autronics US nor any ERISA Affiliate has engaged in a prohibited
transaction, as such term is defined under Code section 4975 or ERISA section
406, which would subject P&G Controls US or Autronics US to any Taxes, penalties
or other Liabilities under Code section 4975 or ERISA sections 409 or 502(i). No
US Company Plan has incurred any "accumulated funding deficiency" as such term
is defined in ERISA section 302 and Code section 412 (whether or not waived),

                     Relevant Members under the Staff Plan and the Cash Plan,
                     and no augmentation, discretion or practice has created an
                     obligation to provide benefits or an expectation of
                     receiving benefits in excess of or different from those set

                     determine their entitlements to benefits under the UK
                     Pension Schemes has been made available by the Sellers to
                     the Purchaser.

                  I. The UK Employer Companies, the UK Business and the

                     fact or circumstance likely to give rise to any such
                     proceedings.

expected to have a Material Adverse Effect.

     Section 3.2  NO IMPLIED REPRESENTATIONS. Notwithstanding anything to the
contrary herein and without in any way affecting Purchaser's right to rely on
the accuracy and completeness of the representations and warranties set forth

BENEFITS.

                                      -28-
<Page>

          A.      COVENANTS REGARDING CLOSING CONDITIONS. The parties shall use
their respective reasonable efforts to bring about the satisfaction as soon as
practicable of all the conditions to Closing contained in Articles VI and VII.
Without limiting the generality of the foregoing, the parties shall apply for
and diligently prosecute all applications for, and shall use their respective
reasonable efforts promptly to obtain, (1) such consents, waivers, releases,
authorizations and approvals from such Governmental Entities as shall be
necessary to permit the consummation of the Contemplated Transactions; (2) such
consents, waivers, valuations, authorizations and approvals as may be required
under the Sellers' Charter Documents; and (3) such consents, waivers, releases,
authorizations and approvals from such third parties as shall be necessary to
permit the consummation of the Contemplated Transactions, provided, in the case
of the Sellers, that this Section 5.1(A)(3) shall only be applicable to such
consents, waivers, releases, authorizations as are described in Section 6.4.

          B.      NON-ASSIGNABILITY. To the extent that any Commitment, claim or
other Asset intended to be assigned to Purchaser or from which Purchaser is
intended to receive benefits or obligations hereunder is not assignable without
the consent of another Person, and such consent is not obtained by Closing, this
Agreement shall not constitute an assignment or an attempted assignment thereof
to Purchaser or an assumption of Sellers' obligations thereunder by Purchaser if
such assignment or attempted assignment and assumption would constitute a breach
thereof. If any such consent or assignment cannot be obtained, then the Seller
or the Company party to, or who owns, the relevant Commitment, claim or other
Asset intended to be assigned to Purchaser or from which Purchaser is intended
to receive benefits or obligations thereunder shall be deemed to hold the
benefit of that Commitment, claim or other Asset in trust for the Purchaser, and
the Purchaser shall (if sub-contracting or agency is permissible under the
relevant Commitment, claim or other Asset) as Seller's sub-contractor or agent
perform on behalf of Seller (but at the Purchaser's expense) all the obligations
of Seller under such Commitment, claim or other Asset; and the Purchaser shall
indemnify such Seller against all costs, expenses or Liabilities incurred by
such Seller as a result of any act, neglect, default or omission on the part of
the Purchaser to perform or comply with any such obligation of such Seller. Such
Seller shall, at the Purchaser's expense, do all such acts and things as the
Purchaser may reasonably request to enable performance of the relevant
Commitment, claim or other Asset and to provide the Purchaser with the benefit
of the relevant Commitment, claim or other Asset (including the enforcement of
any right of such Seller against the other party to the relevant Commitment,
claim or other Asset). Such Seller shall account to the Purchaser for all
monies, goods or other benefits received by Seller under the relevant
Commitment, claim or other Asset in respect of the period after the Closing Date
as soon as reasonably practicable after receipt. Provided Purchaser is not in
breach of this Section 5.1, such Seller shall not agree to any amendment or
termination of the relevant Commitment, claim or other Asset or any waiver by
Seller of its rights under the relevant Commitment, claim or other Asset without
the Purchaser's prior written consent, which shall not be unreasonably withheld
or delayed.

                                      -29-

     In the event of a direct conflict between this Section 5.1(B) and Article
VI of the UK Business Transfer Agreement, this Section 5.1(B) shall control.

     Section 5.2  TAX MATTERS.

     A.   TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE. The Sellers shall
prepare and file or cause to be prepared and filed all Tax Returns for the
Companies and the Businesses for all periods ending on or prior to the Closing
Date which are filed after the Closing Date including income Tax Returns with
respect to periods for which a consolidated, unitary or combined income Tax
Return of all or any number of the Sellers will include the operations of one or
more of the Companies and the Businesses; PROVIDED, HOWEVER, with respect to the
UK Companies, this Section 5.2(A) shall apply only with respect to UK
corporation Tax Returns. Subject to Section 5.2(L) and Section 9.14(C)(vii), the
Sellers shall pay and be liable for all Taxes of the Companies with respect to
such periods or which arise in respect of any event, action, or transaction
which occurred during such periods, or, alternatively with respect to the UK
Companies, shall procure the surrender or transfer to the UK Companies for zero
consideration of sufficient tax reliefs to discharge such Taxes, PROVIDED,
FURTHER, with respect to the UK Companies any amounts payable by the Sellers
under this Section 5.2(A) shall be due and payable to the Purchaser on an after
tax basis. In relation to UK corporation Tax Returns which are relevant for the
purposes of this Section 5.2(A), the Sellers shall also have responsibility for
the agreement of such Tax Returns at Sellers' expense. Where a liability to Tax
arises on the UK Companies under section 179 Taxation of Chargeable Gains Act
1992 the Seller shall, if possible, procure that either it or a company which
remains under the control of the Seller after the date of Closing shall enter
together with the such UK Company into a joint election as referred to in
section 179B Taxation of Chargeable Gains Act 1992. In relation to the UK
Companies, the Sellers shall not submit any Tax Return to any Tax authority or
enter into any communication with any Tax authority without seeking the
Purchaser's consent, which shall not be unreasonably withheld or delayed, unless
such action is consistent with past practices of the UK Companies and does not
involve a Tax liability in excess of $500,000.

     B.   TAX PERIODS BEGINNING ON OR AFTER THE CLOSING DATE. The Purchaser
shall prepare and file or cause to be prepared and filed when due all Tax
Returns for the Companies for all periods beginning on or after the Closing Date
including income Tax Returns with respect to periods for which a consolidated,
unitary or combined income Tax Return of the Purchaser will include the
operations of one or more of the Companies. The Purchaser shall pay all Taxes of
the Companies with respect to such periods.

     C.   TAX PERIODS BEGINNING BEFORE AND ENDING AFTER THE CLOSING DATE. The
Purchaser shall prepare and file or cause to be prepared and filed when due any
Tax Returns of the Companies for Tax periods which begin before the Closing Date
and end after the Closing Date. The Purchaser shall permit the Sellers to review
and comment on each such Tax Return described in the preceding sentence prior to
filing. Subject to Section 5.2(G), the Sellers shall deliver to the Purchaser,
at least three (3) business days prior to the date on which such Taxes are
required to be paid, that portion of the Taxes which relates to the portion of
such taxable period

                                      -30-
<Page>

ending on the Closing Date. For purposes of this Section 5.2(C), in the case of
any Taxes that are imposed on a periodic basis and are payable for a taxable
period that includes (but does not end on) the Closing Date, the portion of such
Tax which relates to the portion of such taxable period ending on the Closing
Date shall (i) in the case of any Taxes other than Taxes based upon or related
to income or receipts, be deemed to be the amount of such Tax for the entire
taxable period multiplied by a fraction the numerator of which is the number of
days in the taxable period ending on the Closing Date and the denominator of
which is the number of days in the entire taxable period, and (ii) in the case
of any Tax based upon or related to income or receipts be deemed equal to the
amount which would be payable if the relevant taxable period ended on the
Closing Date. Subject to the proration provisions of the preceding sentence, any
credits or refunds relating to a taxable period that begins before and ends
after the Closing Date shall be taken into account as though the relevant
taxable period ended on the Closing Date. All determinations necessary to give
effect to the foregoing allocations shall be made in a manner consistent with
prior practice of the Companies.

     D.   US BUSINESS, UK BUSINESS AND GERMAN BUSINESS. Except as specifically
set forth in the US Business Transfer Agreement, the UK Business Transfer
Agreement (including without limitation Article 4 thereof), or the German
Business Transfer Agreement, the provisions of this Section 5.2 shall apply to
Taxes and Tax Returns relating to the US Business, the UK Business or the German
Business. The Sellers shall prepare and file, or cause to be prepared and filed,
all Tax Returns for Spirent GmbH in relation to the German Business for the
period up to and including the Closing Date. The Sellers shall pay, or reimburse
the Purchaser for, those Taxes in relation to the German Business with respect
to such period and for which the Purchaser may become liable according to
Section 75 of the German Tax Code (ABGABENORDNUNG).

     E.   CONTEST PROCEEDINGS. With respect to any Tax Returns for any Tax
periods, the party hereto responsible for the preparation and filing of such Tax
Return shall control the defense of any audits thereof or other Legal
Proceedings relating thereto, PROVIDED that the costs of any such defense shall
be shared by the parties hereto, pro rata based on their responsibility for
Taxes due under any such Tax Return, and PROVIDED FURTHER that no such audits or
other Legal Proceedings shall be settled in a manner which would adversely
affect the other party hereto without the prior written consent of such other
party, which consent shall not be unreasonably withheld.

     F.   DETERMINATION AND ALLOCATION OF CONSIDERATION. The parties to this
Agreement agree to allocate the total consideration transferred by the Purchaser
to the Sellers pursuant to this Agreement (the "CONSIDERATION") amongst the
various assets and liabilities in accordance with SCHEDULE 5.2(F). The Sellers
and the Purchaser agree to prepare, or cause to be prepared, and file, or cause
to be filed, an IRS Form 8594 in a timely fashion in accordance with the rules
under Section 1060 of the Code, consistent with such schedule. To the extent
that the Consideration is adjusted after the Closing Date, the parties agree to
revise and amend the schedule and IRS Form 8594 in a manner consistent with that
used in developing the allocation on said SCHEDULE 5.2(F). The determination and
allocation of the Consideration derived pursuant to this subsection shall be
binding on the parties hereto and their Affiliates for all Tax reporting
purposes.

                                      -31-
<Page>

     G.   TRANSFER TAXES. Payment by the Purchaser to the Sellers of the
Purchase Price shall be made in full without any deduction or withholding,
whether in respect of set-off, counterclaim, or Taxes (other than any Taxes
imposed on the Sellers that are based on net income or profits), unless the
deduction or withholding is required by Law, in which event the Purchaser shall
(1) ensure that such deduction or withholding does not exceed the minimum amount
legally required; (2) pay to the Sellers such additional amount so that the net
amount received by the Sellers shall be the full amount which would have been
received by the Sellers had no such deduction or withholding been made, except
that no additional amount shall be payable to the extent such deduction or
withholding relates to a Tax liability of the Sellers; (3) pay to the relevant
Governmental Entities within the period for payment permitted by applicable Law
the full amount of the deduction or withholding; and (4) furnish to the Sellers
within the period for payment permitted by the relevant Law, a certificate of
deduction or equivalent evidence of the relevant deduction or withholding;
provided that if California Laws require a withholding of part of the
Consideration in connection with the transfer of the US Assets under the US
Business Transfer Agreement on account of unpaid California Taxes owing from
Autronics US, then the parties shall use all commercially reasonable efforts to
obtain a release of such requirement from the applicable authorities by Closing;
if notwithstanding the foregoing no such release can be obtained, then the
Purchaser shall be entitled to make such withholding until such withholding is
no longer required under California Law (at which time the Purchaser shall pay
over such withheld amount to the Sellers), provided such withholding does not
exceed, in any event, $2,000,000. Except as set forth in the foregoing proviso,
all sales, use, transfer, stamp, conveyance, value added or other similar taxes,
duties, excises or governmental charges imposed by any taxing jurisdiction,
domestic or foreign, and all recording or filing fees, notarial fees and other
similar costs with respect to the Transfer of the Shares, the US Assets, the UK
Assets and the German Assets will be borne by the Purchaser.

     H.   COOPERATION ON TAX MATTERS. The Purchaser, the Companies and the
Sellers shall cooperate (and cause their respective Affiliates to cooperate)
fully, as and to the extent reasonably requested by the other parties, in
connection with the preparation and filing of Tax Returns pursuant to this
Section 5.2 and any Tax Audit, litigation or other proceeding with respect to
Taxes and payments in respect thereof. Such cooperation shall include the
retention and (upon the other parties' request) the provision of records and
information which are reasonably relevant to any such Tax Audit, litigation or
other proceeding and making employees available on a mutually convenient basis
to provide additional information and explanation of any material provided
hereunder. The parties shall provide timely notice to the other in writing of
any pending or proposed Tax Audits or assessments with respect to Taxes for
which the other may have an indemnification obligation under this Agreement. The
parties shall furnish the other with copies of all relevant correspondence
received from any taxing authority in connection with any Tax Audit or
information request with respect to any Taxes for which the other may have an
indemnification obligation under this Agreement.

     I.   POWERS OF ATTORNEY. At least five (5) days prior to Closing, the 5
Purchaser shall provide Spirent plc with a schedule listing which powers of
attorney disclosed under SCHEDULE 3.1(E) which Purchaser wants terminated as of
the Closing, and immediately prior to the Closing

                                      -32-
<Page>

Spirent plc (or the respective Company) will use its reasonable efforts to
terminate, or cause to be terminated, each such power of attorney appearing on
the schedule provided by the Purchaser.

     J.   TAX SHARING AGREEMENTS. All tax sharing agreements or similar
agreements with respect to or involving any Company shall be terminated as to
the Companies as of the Closing Date. After the Closing Date, no Company shall
be bound by or have any Liability under any such tax sharing agreement or
similar agreement.

     K.   SELLERS' CONTROL OF UK TAX MATTER. If the disposal of the UK Companies
in accordance with this Agreement gives rise to any charge to UK tax under
section 179 Taxation of Chargeable Gains Act 1992 (or if the UK Inland Revenue
assert that such a charge arise) and provided that neither Purchaser nor any of
its Affiliates including the UK Companies, shall be liable in respect of any
such charge, then the following provisions shall apply:

          (i)     the Sellers shall have the full conduct of negotiating and
                  agreeing such charge with the Inland Revenue;

          (ii)    the Purchaser shall and shall procure that any relevant UK
                  Company shall as soon as is reasonably practicable notify the
                  Sellers of any information which comes to the attention of the
                  Purchaser and/or the UK Company which indicates that such a
                  charge will arise or has arisen, and shall provide the Sellers
                  with such information and assistance as the Sellers shall
                  reasonably require to negotiate and agree the charge with the
                  Inland Revenue; and

          (iii)   the Sellers shall keep the Purchaser promptly informed of the
                  progress of such negotiations and agreement.

     L.   UK TAX RELIEFS.

          (i)     This Section 5.2(L) shall apply in respect of all Schedule D
                  Case I corporation tax losses held by any UK Companies at the
                  Closing which are not reflected in the balance sheets included
                  in the Financial Statements and which are capable of being
                  surrendered by the UK Companies to the Sellers or any other
                  Person connected with the Sellers ("RELEVANT RELIEFS").

          (ii)    At any time following the Closing, the Sellers shall be able
                  to request in writing that the UK Companies surrender the
                  Relevant Reliefs to the Sellers or such other Person as the
                  Sellers shall direct to the extent that this is permissible by
                  Law. It is acknowledged that prior to Closing payment will be
                  made to the UK Companies in consideration of such surrenders.

                                      -33-

          (iii)   The Purchaser shall procure that the UK Companies sign such
                  elections and take such other actions as the Sellers shall
                  require procuring the effective and prompt surrender of the
                  Relevant Reliefs.

          (iv)    The Purchaser shall be under no obligation to procure that the
                  UK Companies make any election under Section 171A TCGA.

          (v)     The Sellers shall not use their powers under this Section
                  5.2(L) so as to create a Tax charge in the UK Companies.

                  covenants and agreements of the Purchaser with respect to the
                  payment of Taxes, including any indemnification agreements
                  relating thereto, set forth in the US Business Transfer
                  Agreement and the UK Business Transfer Agreement.

     N.   JURISDICTION OF EXECUTION.

          (i)     The parties hereto hereby acknowledge and agree that the
Agreement, Additional Transfer Documents and Ancillary Agreements have all been
executed (to the extent executed by the parties) and delivered in the United
States of America and Sellers hereby further covenant and agree with Purchaser
that the original copies of the Agreement, the Additional Transfer Documents and
the Ancillary Agreements shall not be permitted to leave the jurisdiction of the
United States of America without the prior written consent of the Purchaser.
Notwithstanding the foregoing, the Sellers shall be entitled to remove the
original copies of the Agreement, the Additional Transfer Documents and the
Ancillary Agreements outside of the jurisdiction of the United States of America
without the prior written consent of the Purchaser in the event that such
removal is required for the Sellers to enforce any rights under the Agreement,
the Additional Transfer Documents and the Ancillary Agreements (and in which
case the Purchaser shall pay the stamp duty or other Taxes, if any, resulting
from such removal), provided the Sellers are then not in breach of Section 9.13.

          (ii)    The Purchaser acknowledges and agrees with the Sellers that
all UK stamp duty payable in connection with the Contemplated Transactions and
the execution and delivery of the Agreement, the Additional Transfer Documents
and the Ancillary Agreements shall be payable by the Purchaser. If in relation
to any action taken by or matter affecting the Sellers:

                  (A)    A judge, arbitrator or other Person responsible for the
          determination of any proceedings, whether in a tribunal or whether
          judicial, arbitral, administrative or otherwise requires or a Seller
          reasonably considers that such judge, arbitrator or other Person would
          require, that this Agreement, the Additional Transfer Documents or the
          Ancillary Agreements are stamped prior to such document being accepted
          as evidence in the proceedings before them; or

                  (B)    Any Governmental Entity (including any taxation
          authority) or any Person (acting within its powers) acting on behalf
          of a Governmental Entity requires the stamping of this Agreement, the
          Additional Transfer Documents or the Ancillary Agreements;

then the Purchaser agrees that and undertakes to the Sellers that it will pay
any stamp duty (and related interest or penalty charges) which may be payable on
this Agreement, the Additional Transfer Documents or the Ancillary Agreements.

     The Sellers shall use all reasonable endeavours to procure that the Persons
mentioned above accept unstamped copies of this Agreement, the Additional
Transfer Documents or the

                                      -35-
<Page>

     Ancillary Agreements. However, the obligation accepted by the Sellers under
this Section 5.2(N)(ii) shall not extend to incurring any cost, taking any
action against or appealing any decision of the relevant Person.

     If the Purchaser fails to comply with its obligations under this Section
5.2(N)(ii) the Sellers shall be entitled (but not obliged) to pay the relevant
stamp duty (and related interest and penalty charges) and the Purchaser shall be
obliged immediately on demand to pay to the Sellers an amount by way of
liquidated damages (on an after tax basis) equal to the amount paid by the
Sellers.

     O.   CERTAIN PAYMENT COVENANTS. The Sellers covenant with and undertake to
the Purchaser to pay the Purchaser an amount equal to:

          (i)     any Liability to repay in whole or in part any payment
                  received or receivable by the UK Companies or any liability of
                  the UK Companies to make any payment for the surrender of
                  Group Relief (within the meaning of Chapter IV Part X Income
                  and Corporation Taxes Act 1988) pursuant to any arrangement or
                  agreement entered into on or before the Closing Date; and

          (ii)    the loss in whole or in part of the right to receive any
                  payment for Group Relief from any company pursuant to any
                  arrangement or agreement entered into on or before the Closing
                  Date.

     P.   PRIORDISPOSITIONS OF ASSETS. The Sellers shall pay (a) the Taxes due
under Section 179 of the United Kingdom Taxation of Chargeable Gains Act 1992 as
a result of their transfer of the Penny & Giles sensors division from P&G plc to
P&G Controls UK on 1 January 1998; and (b) the Taxes incurred by or due from
Penny & Giles Studio Equipment Limited, a former Affiliate of P&G Controls UK,
relating to periods prior to May 7, 1998.

     Q.   CERTAIN VAT MATTERS REGARDING LEASE ASSIGNMENTS. It is hereby agreed
by the Purchaser that VAT is payable on the consideration paid or to be paid by
the Purchaser in respect of each of the Lease Assignments which shall be in
addition to, in each case, the consideration set out in the Lease Assignments.
The Purchaser hereby agrees to pay to Spirent plc all such VAT payable on each
and all of the Assignments and such payment of VAT shall be paid by the
Purchaser to Spirent plc on or before Friday 31 May 2002. Payment of such sums
shall be received in cleared funds in GB Sterling by Spirent plc by electronic
transfer so that Spirent plc shall receive such sum in its bank account before
2pm (GMT) on Friday 31 May 2002.

     Section 5.3  BOOKS AND RECORDS. Until the earlier of (i) the expiration of
the applicable statute of limitations (including periods of waiver) or (ii) six
(6) years after the Closing Date (or such longer period as may be required by
any Law or any ongoing Legal Proceeding), (1) the Purchaser shall cause the
Companies to maintain all books and records of the Companies material to the
Businesses; and (2) the Sellers shall maintain those books and records which (I)
are material to the US Business, the UK Business and the German Business and
(II) are not provided to Purchaser at or in connection with the Closing; in each
case with respect to the

                                      -36-
<Page>

period up to and including the Closing; and (3) the Purchaser and the Sellers,
respectively, shall permit the Sellers and the Purchaser, respectively, to have
reasonable access to such books, records and data for inspection and copying by
Sellers or Purchaser, respectively, or their respective duly authorized
representatives (at Sellers' or Purchaser's respective expense) upon reasonable
prior written notice, in connection with the preparation of financial reports,
Tax Returns, Tax Audits, the defense or prosecution of litigation, or any other
reasonable need of the Sellers or Purchaser, respectively, to consult such
records and data.

     Section 5.4  DISCHARGE OF LIABILITIES.

          A.      The Purchaser acknowledges that (1) any and all Liabilities of
the Companies at Closing shall continue to be Liabilities of such Companies
unaffected by the Closing and the Transfer of the Shares hereunder, and (2)
without limiting the foregoing, the Sellers are not retaining or assuming any
such Liabilities of the Companies; and the Purchaser covenants and warrants to
the Sellers that following the Closing all such Liabilities of the Companies
shall be paid, discharged and performed by the Companies in accordance with
their respective terms, and all US Liabilities, UK Liabilities and German
Liabilities shall be paid, discharged and performed by the Purchaser in
accordance with their respective terms.

          B.      With respect to any regularly recurring rents, water,
telephone, electricity or other utility charge which is imposed on a periodic
basis and is payable for a period that includes (but does not end on) the
Closing Date, the portion of such charge which relates to the portion of such
period ending on the Closing Date shall be deemed to be the amount of such
charge for such entire period multiplied by a fraction the numerator of which is
the number of days in such period ending on the Closing Date and the denominator
of which is the number of days in the entire such period. The Sellers shall pay
the amount so deemed to relate to the portion of such period prior to Closing,
and the Purchaser shall pay the amount so deemed to relate to the portion of
such period following Closing.

     Section 5.5  INSURANCE. To the extent that any of the Assets suffer damage
prior to the Closing or the Businesses suffer a Liability prior to the Closing,
and both: (a) such Asset or Liability is to be included in Closing Net Worth but
the Closing Net Worth does not reflect such damage or Liability; and (b) the
Sellers (but not the Purchaser or the Companies) are entitled to receive
insurance proceeds on account of such damage or Liability; then at the request
of the Purchaser the Sellers shall take commercially reasonable efforts to
collect such proceeds, and to pay such proceeds to the Purchaser, in each case
to the extent of the amount of such damage or Liability not so reflected in
Closing Net Worth; provided that such obligation of the Sellers shall only be
applicable if the Purchaser reimburses and indemnifies the Sellers from and
against any costs or expenses reasonably incurred in connection with such
collection and payment efforts (including the cost of any deductible).
Notwithstanding the foregoing, the Sellers may, but shall not be obligated to,
elect to pay the amount of such proceeds to which is entitled directly to the
Purchaser without obligation to collect the same under any such insurance
policy. Prior to the Closing, the Sellers shall and shall cause the Companies to
maintain (and not cancel) any insurance in place in the Ordinary Course of
Business under which any Company is an insured or

                                      -37-
<Page>

each of the Sellers is an insured with respect to the US Business, the UK
Business or the German Business, as the case may be.

     Section 5.6  EMPLOYEE/ERISA TRANSITION.

          A.      To the extent that any employee of one of the US Companies or
Autronics US has an outstanding loan under a US Company Plan as of Closing, the
Purchaser shall cause its Code Section 401(k) plan to accept and assume such
loan and allow for repayment under substantially similar terms and conditions.
In addition, the Purchaser and the Sellers agree that they shall reasonably
cooperate with each other with respect to the Sellers' termination of any US
Company Plans. Neither the Purchaser nor the Companies shall have any rights
under or with respect to any such US Company Plans terminated by the Sellers. To
the extent that any provision of this Section 5.6 or the Purchaser Employer
Indemnification is inconsistent with the provisions of the UK Business Transfer
Agreement, the provisions of the UK Business Transfer Agreement, and not this
Section 5.6 or the Purchaser Employer Indemnification, as the case may be, shall
apply to the UK Business Employees (as defined in the UK Business Transfer
Agreement).

     Life insurance will be offered without pre-existing condition only up to
the amount that transferred employees would have been covered under insurance
policies issued by the prior carriers. If the pre-existing condition was
satisfied under the prior carrier's policy then no pre-existing condition
requirement will be required under the Purchaser's plan. The Sellers will be
required to administer and be responsible for all COBRA requirements as
established by Law for all participants prior to the Closing. The Sellers agree
to fully vest all US transferred employees' Code Section 401(k) assets at 100%
at the Closing.

          B.      The Purchaser agrees that, under any employee benefit plan
made available or established by the Purchaser or P&G Controls US after the
Closing, employees of P&G Controls US and Autronics US will receive credit for
their years of service with P&G Controls US or Autronics US, as the case may be,
prior to the Closing in determining eligibility and vesting thereunder and in
determining the amount of benefits under any applicable sick leave, vacation or
severance plan. The Purchaser will cover employees of the US Companies and the
US Business as of the Closing under a group health plan and waive any
pre-existing condition limitations applicable to employees of the US Companies
or the US Business under any group health plan made available to employees of
the US Companies or the US Business to the extent that an employee's condition
would not have operated as a pre-existing condition limitation under any
applicable group health plan of or sponsored by the US Companies or Autronics US
prior to the Closing, and the Purchaser will take all action necessary to ensure
that employees of the US Companies and the US Business are given full credit for
all co-payments and deductibles incurred under any group health plan for the
year that includes the Closing Date.

          C.      If any Spirent Business Employee is neither employed nor
engaged by one of the Companies nor employed nor engaged by P&G plc wholly
engaged in the UK Business immediately before the Closing, then:

                                      -38-
<Page>

          (i)     the Sellers shall notify the Purchaser on or before the
     Closing Date that such Spirent Business Employee is not so employed or
     engaged;

          (ii)    the Purchaser may on or before the Closing Date make or cause
     the relevant Company to make an offer of employment or appointment to such
     Spirent Business Employee to employ or engage such Spirent Business
     Employee with effect from the Closing Date; and

          (iii)   the Sellers may terminate the employment or engagement of such
     Spirent Business Employee with immediate effect without notice or payment
     in lieu within 14 days after the offer in clause (ii) above being made or
     within 14 days after the Closing Date, whichever is later. If no offer is
     made under such clause (ii), the Sellers may terminate such Spirent
     Business Employee's employment or engagement within 14 days after the
     Closing Date with immediate effect without notice or payment in lieu.

As used herein, the term "Spirent Business Employee" means each and all of the
following people: Richard Strugnell, Chris Pritchard, Neil Parke, Joe Oatley,
Raymond New, David Taylor, and William Alfred Penny.

     D.   The Purchaser shall indemnify the Sellers in full for and against all
Liabilities whatsoever and howsoever arising incurred or suffered by any of the
Sellers in relation to the employment or engagement and/or the termination of
employment or engagement of the Spirent Business Employees and/or any other
event or occurrence in respect of the Spirent Business Employees at any time
before, on or after the Closing.

     E.   The Purchaser agrees that Stuart Boulton, Brian Robinson, Wendy Brown,
Todd Scott, Phil Larson and Norman Burkies, all of whom are, or will be at
Closing, employees of an Affiliate of a Seller (other than another Company)
shall be allowed to continue to utilize their existing work space at the UK
Lease Sites, at no rental charge, for a period of 12 months following Closing.
For as long as such persons are employed by a Seller or an Affiliate of the
Seller and continue to utilize such existing work space, the Sellers shall
indemnify the Purchaser for the Purchaser's Liability including its reasonable
costs or expenses caused by any non-compliance by such person with the
Purchaser's reasonable safety and operational requirements generally applicable
to the Purchaser's employees at the UK Lease Sites (provided such persons are
made aware of such requirements), and for the charges for long-distance phone
calls made by such persons from such work space. In connection therewith, to the
extent that any of the foregoing are currently employed by a Company or the UK
Business, the Sellers shall be entitled, prior to Closing, to transfer such
employment arrangement to an Affiliate of a Seller (and to the extent such
employment is transferred to another Seller, such arrangement shall not be
transferred to the Purchaser as part of the Contemplated Transactions); subject
to the Sellers' indemnification obligations set forth in the preceding sentence,
if and as applicable.

          F.      To the extent that any of the Sellers or the Companies are
obligated to pay life insurance premiums through age 65 for former employees of
P&G Controls or the UK

                                      -39-
<Page>

Businesses and who are pensioners of a Spirent pension plan, then the Sellers
following the Closing shall continue to pay these premiums in accordance with
such obligations.

          G.      The Sellers hereby covenant and agree to satisfy prior to or
promptly after Closing, all obligations to pay employee bonuses entitled to be
received by all employees in the Businesses attributable to periods ending on or
prior to Closing or which are due and payable as a result of the consummation of
the Contemplated Transactions; provided such bonuses are not reflected in
Closing Net Worth.

          Section 5.7 USE OF SPIRENT NAME. The Purchaser acknowledges that it is
not acquiring by reason of the Transfer of the Shares, the US Business, the UK
Business or the German Business hereby, any rights to use the name "Spirent" or
any other names, service marks or trademarks of the Sellers (other than, in the
case of such other names, service marks, or trademarks, those identified as
comprising Assets of the US Business, the UK Business and the German Business in
the Additional Transfer Documents); PROVIDED, HOWEVER, that following the
Closing the Companies, the US Business, the UK Business and the German Business
shall be entitled to use (a) the existing inventory of promotional material,
labels, packaging and nameplates with respect to products manufactured and sold
by Sellers prior to the Closing and bearing the Spirent name or any variation
thereof, and to sell existing inventory bearing the Spirent name, if any, and to
use existing signage, stationery, invoices and other office supplies bearing the
Spirent name, if any, in the Ordinary Course of their Businesses, provided that
(1) in the case of promotional materials only, such usage is terminated as soon
as is reasonably practical following the Closing Date; and (2) in the case of
all of the foregoing other than promotional materials: (A) from and after the
date which is 90 days following the Closing Date (subject to the succeeding
sub-clause (B)), the Spirent name is stickered over or otherwise deleted from
any of the foregoing; and (B) such usage does not, in any event, extend past the
date which is one hundred eighty (180) days following the Closing Date. The
parties agree that as a result of the transactions contemplated by this
Agreement and the Additional Transfer Documents, the Purchaser will thereby be
acquiring royalty free and unrestricted rights to use the names "Penny & Giles"
and "P&G." The Purchaser acknowledges that such rights are non-exclusive, in
that Spirent plc or its Affiliates have previously granted third parties certain
rights to use such names to the entities set forth on SCHEDULE 5.7, but Spirent
plc represents that such no such third party grantees are using such names in
any material commercial respect except as set disclosed on SCHEDULE 5.7; and
that such previous grants do not (A) materially impair the usage rights of the
Purchaser referred to in the preceding sentence; or (B) require any payments by,
or continuing obligations of, the Purchaser. Spirent plc agrees that neither it
nor its Affiliates will (a) after the Closing hold themselves out as doing
business under such names (provided that this covenant shall not prohibit
Spirent plc or such Affiliates from using existing stationery and other office
supplies bearing the Spirent name, if any, in the Ordinary Course of their
Businesses, but in no event past the date which is sixty (60) days following the
Closing Date); or (b) after the date hereof grant to any Person any rights to
use such names and in furtherance of the foregoing Spirent plc agrees that it
shall cause P & G plc to change its corporate name at or prior to the Closing
and to delete therefrom any reference to "Penny & Giles", "P&G" or any variation
thereof. Notwithstanding the foregoing, Spirent plc shall cause "Penny & Giles
Drives Technology Ltd," "Penny & Giles Drives Technology Division of Autronics
Corporation" and

                                      -40-
<Page>

"Penny & Giles Drives Technology Asia" to change its corporate name at or prior
to the Closing and to delete therefrom any reference to "Penny & Giles", "P&G"
or any variation thereof, provided that any such new corporate name may include
the letters "PG." The Purchaser hereto acknowledges that neither it nor the
Companies will have any rights from and after the Closing to create or maintain
any website links to or from any website of Spirent plc or its Affiliates. The
Sellers acknowledge they will not have any rights from and after the Closing to
create or maintain any website links to or from any website of any Company.

     Section 5.8  GUARANTEES. The Purchaser shall use best efforts to (a)
deliver on or prior to the Closing Date but effective as of the Closing,
Guaranty/Bond Replacements for each Guaranty or Bond listed on SCHEDULE 5.8; and
(b) procure, after the Closing, Guaranty/Bond Replacements for any Guaranty or
Bond not listed on SCHEDULE 5.8 and issued or obtained in the Ordinary Course of
Business prior to the Closing Date, with such Guaranty/Bond Replacements to be
so obtained as promptly as reasonably practicable after the Purchaser learns of
the same; provided that, in the case of this clause (b): (1) the procurement of
any such Guaranty/Bond Replacement shall not constitute a waiver of any breach
of this Agreement by the Sellers; and (2) the Purchaser shall not be required to
procure any such Guaranty/Bond Replacement following the Closing to the extent
that the same will result in more than $1,000 of cost or expense to the
Purchaser, unless the Sellers agree to reimburse the Purchaser for such cost or
expense. Pending such procurement as described in the foregoing clause (b)
(including if such procurement is not required by sub-clause (2) of the
foregoing clause (b)), the Purchaser shall indemnify the Sellers and each such
Non-Company Affiliate against all and any liabilities, losses, costs, charges,
proceedings, actions, claims, demands or expenses arising out of or in
connection with any such Guaranty or Bond.

          As used herein, the term "GUARANTY/BOND REPLACEMENT" means any
guaranties, bonds, consideration or other undertakings, as the case may be,
needed to replace and terminate any Guaranty or Bond and so as to obtain the
complete and unconditional release of the Sellers and any Non-Company Affiliates
from all obligations in connection with each such Guaranty or Bond.

          As used herein, the term "GUARANTY OR BOND" means any guaranty,
keepwell agreement, comfort letter, or similar undertaking issued prior to the
Closing Date to or for the benefit of, or any letter of credit, surety bond,
performance bond, customs bond, excise bond or similar undertaking obtained
prior to the Closing Date by, any Seller or any Non-Company Affiliate to support
or facilitate business transactions by a Company, the US Business, the UK
Business or the German Business, and any security furnished by a Seller or any
such Non-Company Affiliate in connection therewith.

          As used herein, the term "NON-COMPANY AFFILIATE" means any Affiliate
of any Seller or of any Company, but such term shall not include any Company.

     Section 5.9  INTERCOMPANY ACCOUNTS. All intercompany accounts or loans
between any Company, the US Business, the UK Business or the German Business, on
the one hand, and any Seller or other Affiliate (other than another Company) or
non-transferred employee, on the other

                                      -41-
<Page>

hand, shall be repaid, capitalized or otherwise eliminated by such Seller or
such Affiliate or such non-transferred employee, on the one hand, and such
Company, the US Business, the UK Business or the German Business, on the other
hand, as applicable, not later than as of the close of business on the Business
Day immediately preceding the Closing Date, except for trade payables and
receivables arising in the Ordinary Course of Business.

     Section 5.10 INDEMNIFICATION OF DIRECTORS AND OFFICERS. Following the
Closing, the Purchaser shall cause each Company to honor its obligations, if
any, to indemnify and advance defense costs to each present and former officer
or director of such Company pursuant to its Charter Documents and shall not
permit the Charter Documents of any Company to be amended for a period of six
years in a manner which materially adversely affects the indemnification rights,
if any, of present and former directors and officers of such Company, except as
required by applicable Laws or unless such obligations are fully covered by
insurance secured by Purchaser or such former officers or directors are fully
covered under comparable provisions of the Charter Documents of Affiliates of
Purchaser, or successors in interest of any Company, in either case during such
six year period, provided that the Purchaser or any such Affiliate, as
applicable, is reasonably comparable in financial strength and credit-worthiness
to such Company.

     Section 5.11 CONTACT WITH CUSTOMERS AND SUPPLIERS. After the date hereof
but prior to the Closing Date, except as specifically authorized herein, none of
the Purchaser or any of its agents, Affiliates, employees, directors or officers
shall contact or communicate with any employees, customers, suppliers or
licensors of any Company, the US Business, the UK Business or the German
Business in connection with the transactions contemplated hereby except with the
prior written consent of Spirent plc, which shall not be unreasonably withheld
or delayed.

     Section 5.12 ACCESS AND INVESTIGATION. Prior to the Closing, upon
reasonable notice from the Purchaser to the Sellers given in accordance with
this Agreement, the Sellers will afford to the officers, attorneys, accountants
or other authorized representatives of the Purchaser reasonable access during
normal business hours to the facilities, assets, books and records, and
management personnel of the Companies, Autronics US (to the extent relating to
the US Business), P&G plc (to the extent relating to the UK Business) Spirent
plc (with respect to the UK Lease Sites), and Spirent GmbH (to the extent
relating to the German Business), so as to afford the Purchaser a reasonable
opportunity to make, at its sole cost and expense, such additional review,
examination and investigation of the Companies, the Assets, the US Business, the
UK Business, and the German Business as the Purchaser may reasonably desire to
make; PROVIDED, HOWEVER, that the Purchaser shall not be permitted such access
to the extent that the Sellers or the Companies are prohibited from granting
such access pursuant to any Law, Order or rule of any regulatory body applicable
to any Seller or any Company wherever located. Sellers shall instruct their
accountants and advisers to reasonably cooperate with the Purchaser and to
provide Purchaser with reasonable access to such accountants (including their
work papers to the extent available to the Sellers) and advisers, all at
Purchaser's cost and expense. Whether or not the Closing occurs, the Purchaser
will, and will cause each of its Affiliates and authorized representatives to,
treat in confidence and not disclose any and all documents, materials and

                                      -42-
<Page>

other information disclosed by or on behalf of the Sellers, the Companies or any
of their respective Affiliates, whether before, during or after the course of
the negotiations leading to the execution of this Agreement or thereafter, in
accordance with that certain Confidentiality Agreement between the Sellers and
the Purchaser dated October 3, 2001 (the "CONFIDENTIALITY AGREEMENT"), provided
that if the Closing occurs, the Confidentiality Agreement shall no longer be
applicable to any such documents, materials or other information which relate to
the Companies or the Businesses, or which constitute Assets.

     Section 5.13 OPERATION OF THE BUSINESSES. Between the date of this
Agreement and the Closing, except as otherwise expressly provided in or
contemplated by this Agreement or waived or consented to by Purchaser in
writing, the Sellers shall cause the Companies to, and each of Autronics US, P&G

the US Business), P&G plc (to the extent relating to the UK Business), Spirent

extent relating to the German Business);

          C.      confer with the Purchaser concerning operational and financial

<Page>

          H.      not permit any Company to (1) amend its Charter Documents, (2)
issue, sell, redeem or otherwise acquire any capital stock, bonds, debentures,
notes or other securities or grant any options (including any employee stock

or delivery of any capital stock, bonds, debentures, notes or other securities,
or (3) declare, or set aside for payment, any dividend to be paid subsequent to
the Closing Date;

          I.      shall not enter into any material transaction with any
Affiliate except on commercially reasonable terms and in the Ordinary Course of
Business;

          J.      not grant material salary or wage increases, or change or
amend any benefit plan covering transferred employees in any way that materially
changes the amount such employees are entitled to receive under such plan other
than pursuant to existing salary and wage plans except in the Ordinary Course of
Business; and

          K.      not take any action or otherwise omit to take any action which
                  would reasonably be expected to cause a breach of the Sellers'
                  representations, warranties, covenants and agreements herein
                  set forth.

PROVIDED, HOWEVER, that no provision of this Agreement (including Section 3.1(D)
and this Section 5.13) shall restrict the ability of any Company, Autronics US,
P&G plc or Spirent GmbH, on or prior to the close of the Business Day
immediately preceding the Closing Date, to distribute all or any portion of its
cash, cash equivalents and intercompany accounts receivable or use all or any
portion of its cash and cash equivalents. The Sellers shall, prior to the
Closing Date transfer to any Affiliate the capital stock of, the companies
listed on SCHEDULE 5.13.

     Section 5.14 NOTIFICATION. Between the date of this Agreement and the
Closing, the Sellers will promptly notify the Purchaser in writing if the
Sellers become aware of any fact or condition that causes or constitutes a
breach of any of the Sellers' representations and warranties as of the date of
this Agreement, or if the Sellers become aware of the occurrence after the date
of this Agreement of any fact or condition that would (except as expressly
required by this Agreement) cause or constitute a breach of any such
representation or warranty had such representation or warranty been made as of
the time of occurrence or discovery of such fact or condition. Should any such
fact or condition require any change in the Disclosure Schedule hereto if such
Disclosure Schedule were dated the date of the occurrence or discovery of any
such fact or condition, the Sellers will promptly deliver to the Purchaser a
supplement to the Disclosure Schedule (a "DISCLOSURE SUPPLEMENT") specifying
such change. No Material Supplement delivered pursuant to this Section 5.14
shall be deemed to cure any breach of any representation or warranty made in
this Agreement for the purposes of a determination by the Purchaser that the
conditions of Article VI shall have been met, but pursuant to Section 6.1(A), if
the Closing occurs, the Disclosure Schedule as so supplemented by a Material
Supplement shall be the Disclosure Schedule for all purposes under this
Agreement. A Disclosure Supplement other than a Material Supplement shall be
deemed to cure any breach of any representation or

                                      -44-
<Page>

warranty made in this Agreement for the purposes of a determination by the
Purchaser that the conditions of Article VI shall have been met.

     As used herein, the term "MATERIAL SUPPLEMENT" means a Disclosure
Supplement delivered by the Sellers to the Purchaser pursuant to this Section
5.14 and which discloses a fact or condition which is reasonably likely to
result in a Material Adverse Effect and has not previously been disclosed within
the Disclosure Schedule.

     Section 5.15 NO SOLICITATION OR NEGOTIATION. The Sellers will not, nor will
they authorize any Company or any other Affiliate or any officer, director or
employee of, or any investment banker, attorney or other advisor or
representative of, the Sellers or any Company or any Affiliate to, directly or
indirectly, solicit, initiate, or encourage any inquiries or proposals from any
Person (other than the Purchaser) relating to any transaction involving the sale
of all or any part of the Shares or the Businesses, other than sales of Assets
in the Ordinary Course of Business, or any merger, consolidation, business
combination, or similar transaction involving any Company (any such transaction,
a "COMPETING TRANSACTION") or participate in any discussions or negotiations
regarding, or furnish to any Person any information with respect to, any
Competing Transaction.

     Section 5.16 PUBLICITY. No press release or public announcement related to
this Agreement, or the transactions contemplated hereby, shall be issued or made
without the joint approval of Spirent plc and the Purchaser, unless required by
Law (in the reasonable opinion of counsel) or London Stock Exchange Limited, the
United Kingdom Panel on Mergers and Acquisitions, New York Stock Exchange or US
Securities and Exchange Commission or other Governmental Entity rule or
regulation, in which case Spirent plc and the Purchaser shall use reasonable
efforts to give the other the opportunity to review such press release or
announcement prior to publication and, where practicable, agree to the form and
wording of such release or announcement.

     Section 5.17 NON-COMPETITION AND NON-SOLICITATION. Prior to the third
anniversary of the Closing Date, the Sellers shall not engage in any Competitive
Business, and the Sellers shall cause their Affiliates not to, directly or
indirectly, own, manage, operate, engage in or control, anywhere in the world,
any Competitive Business; PROVIDED that this Section 5.17 shall not prevent any
of the Sellers or any of their respective Affiliates from (i) owning, solely as
an investment, publicly traded company securities issued by a Person engaged in
a Competitive Business so long as such Seller or Affiliate does not own or
control, in the aggregate, more than 15% of any class of such securities; or
(ii) acquiring or holding any interest in, or managing, operating or
controlling, any Person engaged in Competitive Business if less than 30% of the
total revenues attributable to such Person in the 12 months prior to such
acquisition, or the commencement of the management, operation or control of such
Person by any such Seller or Affiliate, arose out of or were related to such
Competitive Business.

     Prior to the third anniversary of the Closing Date, the Sellers shall not,
and the Sellers shall cause their Affiliates not to, solicit or attempt to hire
or retain any employee of Purchaser, except pursuant to a general solicitation
not aimed at the Purchaser's employees, provided this

                                      -45-
<Page>

covenant shall not prohibit the Sellers or any Affiliate of the Sellers from
hiring any person who leaves the employment of the Purchaser not in response to
a solicitation by the Sellers or their Affiliates.

     As used above, the term "COMPETITIVE BUSINESS" means each of the following
businesses: (1) the manufacture and sale of aerospace sensors and controls
hardware; and (2) the manufacture and sale of aerospace quick access recorders,
primary air data computers, crash protected flight recorders and cockpit voice
recorders; (3) the manufacture and sale of industrial sensors, industrial
joysticks, and industrial studio faders; (4) the manufacture and sale of
aerospace fire protection equipment including smoke detectors and associated
cockpit and control units; (5) the manufacture and sale of aerospace control
electronics including electronic flap controllers, data converter/concentration
units, engine overspeed detectors and sensors, torque sensors and current
detectors; and (6) the manufacture and sale of power supplies for
In-Flight-Entertainment (IFE) and military applications, but only to the extent
any such sales referred to in the foregoing clauses (1) through (6), inclusive,
are for military and commercial aircraft OEMs, aircraft operators or aircraft
suppliers; in each case as conducted as of the Closing Date by the US Business,
the UK Business and the German Business; provided, however, that the term
"Competitive Business" shall not include, in any event:

          (A)     the design, development or sale of software applications
     focused on operational performance, safety assurance, improved efficiency
     or customer service; or systems integration, implementation and consultancy
     services for such performance software products;

          (B)     the design, development or sale of aerospace maintenance,
     repair and overhaul (MRO) software packages;

          (C)     the design, development or sale of aerospace data acquisition,
     networking and display devices;

          (D)     the performance by Spirent Systems Wichita, Inc. under its
     contract with Gulfstream for the SSCVR, Part Number 89095-0031, and any
     follow on business relating to such contract; or

          (E)     the distribution or supply of hardware products manufactured
     by Persons which are not Affiliates of the Sellers, as part of any of the
     foregoing.

          If a final judgment of a court or tribunal of competent jurisdiction
determines that any term or provision contained in this Section 5.17 is invalid
or unenforceable, then the parties agree that the court or tribunal will have
the power to reduce the scope, duration or geographic area of the term or
provision, to delete specific words or phrases or to replace any invalid or
unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision. This

                                      -46-
<Page>

Section 5.17 will be enforceable as so modified after the expiration of the time
within which the judgment may be appealed. This Section 5.17 is reasonable and
necessary to protect and preserve Purchaser's legitimate business interests and
the value of the Assets and to prevent any unfair advantage conferred on
Sellers.

     Section 5.18 FURTHER ASSURANCES. At any time and from time to time, Sellers
on the one hand, and Purchaser, on the other hand, shall promptly execute,
acknowledge and deliver any other assurances or documents reasonably requested
by the other, as the case may be, and necessary for it, as the case may be, to
satisfy its respective obligations hereunder or obtain the benefits contemplated
hereby. The Sellers shall pay over to the Purchaser, as promptly as reasonably
practical, any amounts received by the Sellers from account debtors in payment
of accounts receivable arising prior to Closing and constituting Assets.

     Section 5.19 CERTAIN MATTERS INVOLVING INTELLECTUAL PROPERTY. As soon as
practicable after the Closing Date, Sellers and the Purchaser will cooperate to
take, or cause to be taken, at the Purchaser's expense, all necessary steps to
record with the appropriate United States Governmental Entities the transfer
from the Sellers or any of their Affiliates, as the case may be, to the
Purchaser or other Person designated in writing to Spirent plc at least five (5)
days prior to the Closing Date, of all Intellectual Property previously
registered or patented in the United States and identified as such on SCHEDULE
3.1(G). As soon as practicable after the Closing Date, Sellers and the Purchaser
will cooperate to take, or cause to be taken, at the Purchaser's expense, all
necessary steps to record with the appropriate foreign Governmental Entities or
agents the transfer of all Intellectual Property previously registered or
patented in such jurisdictions and identified as such on SCHEDULE 3.1(G) and to
otherwise record or evidence Purchaser's or its designees' rights in and to such
Intellectual Property, including the filing or amendment of any registered user
certificates, licenses, agreements or similar documents.

     Section 5.20 TRANSITION SERVICES. Spirent plc shall provide the use of
Spirent plc's head office server for the purpose of maintaining the German
Business's global address book for a period of up to 1 month from the Closing
Date and at no cost to the Purchaser or the German Business. Spirent GmbH shall
provide, with respect to the German Business, such accounting, administrative
and human resource services as were provided prior to the Closing Date for a
period of up to six months from the Closing Date at a cost to the Purchaser of
$4,500 per month. The cost of such services will be paid to Spirent GmbH by the
Purchaser within 14 days of receipt from Spirent GmbH of the appropriate
invoice. For the avoidance of doubt Spirent GmbH shall not be required to assist
the Purchaser in respect of the hiring of any further employees for the German
Business in the period referred to above. The Purchaser shall use its best
commercially practicable efforts to replace the services provided by the Spirent
plc and Spirent GmbH with its own arrangements as soon as possible after the
Closing Date. In addition, the Purchaser shall cause the Companies to continue
to host the internet links for Spirent plc's Affiliates to the Companies'
current aerospace wide area network (WAN), at no charge, for three months
following the Closing.

                                   ARTICLE VI

           Conditions Precedent to the Purchaser's Obligation to Close

     The Purchaser's obligation to purchase the Shares, the US Business,
the UK Business and the German Business, and to take the other actions required
to be taken by the Purchaser at the Closing, is subject to the satisfaction, at
or prior to the Closing, of each of the following conditions (any of which may
be waived by the Purchaser, in whole or in part):

     Section 6.1  ACCURACY OF REPRESENTATIONS. The Sellers' representations
and warranties in this Agreement, taken as a whole, must have been materially
accurate as of the date of this Agreement, and must have been materially
accurate as of the Closing Date as if made on the Closing Date (provided that
with respect to any specific representations and warranties which are qualified
by materiality or Material Adverse Effect, the term "materially accurate" as
used in this sentence shall be deemed to be interpreted as "fully accurate");
and the Sellers' representation and warranty in Section 3.1(B)(ii) must have
been fully accurate as of the date of this Agreement, and must have been fully
accurate as of the Closing Date as if made on the Closing Date; in each case
giving effect to each Disclosure Supplement which is not a Material Supplement,
PROVIDED that if the Closing occurs, the Disclosure Schedule as so supplemented
by a Material Supplement shall be the Disclosure Schedule for all purposes under
this Agreement.

     Section 6.2  SELLERS' PERFORMANCE. Each of the covenants and obligations
that the Sellers are required to perform or to comply with pursuant to this
Agreement at or prior to the Closing must have been duly performed and complied
with in all material respects, and the Sellers must have executed and delivered
each of the documents required to be delivered by them, except to the extent
that any such failure to so perform, comply or deliver (other than for the
obligation to execute and deliver the Additional Transfer Documents and
Ancillary Agreements) does not (a) result in a Material Adverse Effect or (b)
substantially impair the Sellers' ability to satisfy their obligations hereunder
and under the Additional Transfer Documents and the Ancillary Agreements.

     Section 6.3  NO INJUNCTION. Since the date of this Agreement, there must
not be in effect any injunction or other Order issued by a court of competent
jurisdiction restraining or prohibiting the consummation of the transactions
contemplated by this Agreement, or in any Additional Transfer Document or any
Ancillary Agreement, including the Transfer of the Shares, the US Business, the
UK Business and the German Business (collectively, the "CONTEMPLATED
TRANSACTIONS").

     Section 6.4  CONSENTS. So long as the Purchaser shall have satisfied its
respective reasonable efforts promptly to obtain the consents listed on SCHEDULE
6.4 pursuant to Section 5.1(B)(2), each such consent must have been obtained and
must be in full force and effect; provided, however, that, with respect to any
such consent, other than the consents required for the transfer of the (i) UK
Lease Site Leases; and (ii) and the Autronics US lease; as identified on said
Schedule, this condition shall be deemed to have been satisfied with respect to
such consent even if such consent has not been so obtained (or is not in full
force and effect), provided that the

                                      -48-
<Page>

Sellers have complied with their obligations under Section 5.1(B)(2) with
respect to the relevant Commitment, claim or other Asset intended to be assigned
to Purchaser whose Transfer requires such consent; provided further, however,
that such condition shall be deemed to have been satisfied with respect to such
consent pursuant to the foregoing proviso of this Section 6.4 if the Sellers
elect to agree to indemnify, from and after the Closing, the Purchaser and the
Companies from and against all Liabilities, costs and expenses incurred by the
Purchaser or the Companies as a result of the Seller's failure to obtain such
consent (or to keep such consent in full force and effect). Such indemnification
obligation, if so elected, is referred to as the "Sellers' Consent
Indemnification."

     Section 6.5  NO PROHIBITION. The proposed Transfer of the Shares, the US
Business, the UK Business and the German Business contemplated hereunder will
not materially contravene, or materially conflict with, or result in a material
violation of any applicable Law or Order, provided that the Purchaser shall have
used commercially reasonable efforts with the Sellers to restructure such
Transfer in a manner which will not so contravene, conflict with or violate such
Law or Order, provided that the foregoing proviso shall not obligate the
Purchaser to agree to any such restructuring to the extent materially altering
the responsibilities, obligations or Liabilities of the Purchaser or the value
of the acquired Businesses or Assets, as determined by the Purchaser in the
Purchaser's reasonable discretion.

                                   ARTICLE VII

            Conditions Precedent to the Sellers' Obligation to Close

by the Sellers, in whole or in part):

     Section 7.1  ACCURACY OF REPRESENTATIONS. The Purchaser's representations
and warranties in this Agreement, taken as a whole, must have been materially
accurate as of the date of this Agreement and must be materially accurate as of
the Closing Date as if made on the Closing Date; and the Purchaser's
representation and warranty in Section 4.1(B)(ii) must have been fully accurate
as of the date of this Agreement, and must have been fully accurate as of the
Closing Date as if made on the Closing Date.

     Section 7.2  PURCHASER'S PERFORMANCE. Each of the covenants and obligations
that the Purchaser is required to perform or to comply with pursuant to this
Agreement at or prior to the Closing must have been duly performed and complied
with in all material respects, and the Purchaser must have delivered each of the
documents required to be delivered by it, except to the extent that any such
failure to so perform, comply or deliver does not (a) result in a material
adverse effect on the Purchaser or (b) substantially impair the Purchaser's
ability to satisfy its obligations hereunder and under the Additional Transfer
Documents and Ancillary Agreements.

                                      -49-

     Section 7.3  NO INJUNCTION. There shall not be in effect any injunction or
other Order issued by a court of competent jurisdiction restraining or
prohibiting the consummation of the Contemplated Transactions.

     Section 7.4  NO PROHIBITION. The proposed Transfer of the Shares, the US
Business, the UK Business and the German Business contemplated hereunder will
not materially contravene, or materially conflict with, or result in a material
violation of any applicable Law or Order, provided that the Sellers shall have
used commercially reasonable efforts with the Purchaser to restructure such
Transfer in a manner which will not so contravene, conflict with or violate such
Law or Order, provided that the foregoing proviso shall not obligate the Sellers
to agree to any such restructuring to the extent materially altering the
responsibilities, obligations or Liabilities of the Sellers, as determined by
the Sellers in the Sellers' reasonable discretion.

                                  ARTICLE VIII

                               Termination Events

     Section 8.1  TERMINATION EVENTS. This Agreement may, by notice given prior
to or at the Closing, be terminated:

          A.      by mutual consent of the Purchaser and the Sellers;

          B.      (i) by the Purchaser, if any of the conditions in Article VI

condition is or becomes impossible (other than through the failure of the
Purchaser to comply with its obligations under this Agreement) and the Purchaser
has not waived such condition at or before the Closing; or (ii) by the Sellers,
if any of the conditions in Article VII has not been satisfied as of the Closing
or if satisfaction of any such condition is or becomes impossible (other than
through the failure of the Sellers to comply with their obligations under this
Agreement) and the Sellers have not waived such condition at or before the
Closing; or

          C.      by either the Purchaser or the Sellers if the Closing has not

Agreement to comply fully with its obligations under this Agreement) on or
before July 1, 2002 or such later date as the parties may agree upon.

     Section 8.2  PROCEDURES FOR TERMINATION. In the event of termination by the
Sellers or the Purchaser pursuant to Section 8.1, written notice thereof shall
forthwith be given to the other party in accordance with Section 9.8, and the
Contemplated Transactions shall be terminated without further action by any
party. If the transactions contemplated by this Agreement are terminated as
provided herein, the Purchaser shall return to the Sellers all documents and
other materials received from the Sellers, the Companies and their respective
Affiliates, representatives and agents relating to the transactions contemplated
hereby, whether obtained before or after the execution hereof, along with all
copies of such documents and other materials; and the Purchaser shall return to
the Sellers or destroy all materials developed by the Purchaser

                                      -50-

other materials. All confidential information received by the Purchaser with
respect to the Sellers and their respective Affiliates shall be treated in

the last sentence of Section 5.12, shall remain in full force and effect
notwithstanding the termination of this Agreement.

     Section 8.3  EFFECT OF TERMINATION. If this Agreement is terminated
pursuant to Section 8.1, all further obligations of the parties under this
Agreement will terminate, except that the obligations in Section 5.16
(Publicity) and Section 9.7 (Expenses) of this Agreement, and the
Confidentiality Agreement, will survive notwithstanding such termination;
PROVIDED, HOWEVER, that nothing in this Section 8.3 shall be deemed to adversely
affect any terminating party's right to pursue all legal remedies available to
such party or to release any party from any liability for any breach of this
Agreement prior to such termination, which remedies and liability shall survive
such termination; PROVIDED FURTHER, HOWEVER, that if the Purchaser terminates
this Agreement under Section 8.1(b)(i) on the basis that the condition in
Section 6.1 has failed to have been satisfied given the facts or matters
disclosed in a Material Supplement, then such termination shall be Purchaser's
sole remedy, and neither the Sellers nor the Purchaser shall have any further
liability or obligation, with respect to the same.

to the Transfer of the UK Business pursuant to the provisions of the UK Business
Transfer Agreement; and (b) with respect to the Transfer of the German Business
pursuant to the provisions of the German Business Transfer Agreement; this
Agreement and the legal relations among the parties hereto shall be governed and
construed in accordance with the substantive Laws of the State of New York, USA,
without giving effect to the principles of conflict of laws thereof. Without
limiting the generality of the foregoing, all claims for indemnification under
Section 9.14 of this Agreement shall be governed by such Laws as aforesaid, even
if any such claim for indemnification relates to the UK Business or the German
Business.

     Section 9.10 SEVERABILITY. If any provisions hereof shall be held by any
court of competent jurisdiction to be illegal, void, or unenforceable, such
provisions shall be of no force and effect, but the illegality or
unenforceability shall have no effect upon, and shall not impair the
enforceability of, any other provision of this Agreement.

     Section 9.11 KNOWLEDGE. Whenever "to its knowledge," "known" "aware,"
"awareness," or a similar phrase is used with respect to any Seller to qualify a
representation or warranty of such Seller, the "knowledge" or "awareness" so
referred to shall be deemed to be the actual and conscious (and not
constructive) knowledge of the Named Individuals. As used above, the term "NAMED
INDIVIDUALS" means those individuals listed on SCHEDULE 9.11. Whenever "to its
knowledge," "known" or a similar phrase is used with respect to the Purchaser to
qualify a representation or warranty of the Purchaser, or as used in Section
4.1(F) and Section 9.14(C)(iii)(c), the "knowledge" so referred to shall be
deemed to be the actual and conscious (and not constructive) knowledge of David
Adams, Michael Denton, George Yohrling, Randy Kesterson, Frank Tartaglia, Al
Symonds, Jameel Barkat, Brian Freeman, Michelle Stalder, and Marcel Dubsky;
provided, however, that for purposes of Section 4.1(F) and Section

any of the matters set forth in the "data room" made available, at the offices
of Goulston & Storrs. P.C., to the Purchaser in connection with this Agreement
or in any statement, representation or warranty or other information contained
in any offering memorandum, management presentation or any other document or
material provided by the Sellers or their representatives or agents to the
Purchaser or its Affiliates in connection with this Agreement.

     Section 9.12 RIGHTS OF THIRD PARTIES. Nothing expressed or implied in this
Agreement is intended or will be construed to confer upon or give any Person
other than the parties hereto and their respective successors and permitted
assigns any rights or remedies under or by reason of this Agreement or any
transaction contemplated hereby.

     Section 9.13 CONSENT TO JURISDICTION AND SERVICE OF PROCESS. Except as
otherwise provided with respect to the Transfer of the UK Business pursuant to
the provisions of the UK Business Transfer Agreement and with respect to the
Transfer of the German Business pursuant to the provisions of the German UK
Transfer Agreement, the Purchaser and each of the Sellers hereby irrevocably
consents that any legal action or proceeding against it under, arising out of,
or in any manner relating to this Agreement or any other agreement, document or
instrument arising out of or executed in connection with this Agreement shall be
brought only in a state or federal

                                      -54-

court of competent jurisdiction located within the Southern District of New York
and in all appellate courts associated therewith. Each party by the execution
and delivery of this Agreement expressly and irrevocably consents and submits to
the personal jurisdiction of any of such courts in any such action or
proceeding. Each party hereby expressly and irrevocably waives any claim or
defense in any action or proceeding based on any alleged lack of personal
jurisdiction, improper venue, forum non conveniens, or any similar basis.

     Section 9.14 INDEMNIFICATION; SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

          A.      INDEMNIFICATION BY SELLERS. Each Seller shall jointly and
severally indemnify, defend and hold harmless the Purchaser and its Affiliates
and their respective employees, officers, directors, stockholders, partners and
representatives from and against any losses, assessments, Liabilities, claims,
damages, costs and expenses (including reasonable attorneys' fees and
disbursements) incurred by such indemnified party as the result of:

          (1) any misrepresentation in, breach of or failure to comply with, any
of the representations, warranties, covenants or agreements of the Sellers
contained in this Agreement or any Additional Transfer Document or Ancillary
Agreement;

          (2) the Dorset Environmental Matter (as defined below);

of companies who were members of the Penny & Giles International Plc &
Associated Companies Pension & Assurance Scheme or who otherwise claim to be
entitled to benefits as set out in clause 9 of the main terms and conditions of
employment issued in February 1986 by Penny & Giles Transducers Limited insofar
as such claims relate to a promise made and service prior to Closing and insofar
as such pension or other relevant benefits will not be paid from either or both
of the UK Company Plans; or

          (6) any claims in respect of the exclusion prior to Closing of UK
Employee Companies from membership of the UK Company Plans for service prior to
October 1991 on the grounds of their part time employee status and for service
between October 1991 and 28 December 1994 on the grounds of earnings less than
the National Insurance lower earnings limit in breach of article 141 of the
Treaty of Rome or of any statute under the laws of the United Kingdom prior to
Closing;

                                      -55-
<Page>

and all such losses, assessments, Liabilities, claims, damages, costs and
expenses are referred to hereinafter as the "PURCHASER'S LOSSES."

     As used herein, the term "Dorset Environmental Matter" means the release or
alleged release of Hazardous Material on the car park at the 1 Airfield Road,
Christchurch, UK facility on Monday 3 December 2001, which resulted from damage
to a waste tank valve caused in connection with the removal by Linkwaste of
waste varnish from that facility.

          B.      INDEMNIFICATION BY THE PURCHASER. The Purchaser shall
indemnify, defend and hold harmless each Seller and its Affiliates and their
respective employees, officers, directors, stockholders, partners and
representatives from and against any losses, assessments, Liabilities, claims,
damages, costs and expenses (including reasonable attorneys' fees and
disbursements) incurred by such indemnified party as the result of:

          (1)     any misrepresentation in, breach of or failure to comply with,
any of the representations, warranties, covenants or agreements of the Purchaser
contained in this Agreement or any Additional Transfer Document or Ancillary
Agreement; or

          (2)     without limiting the generality of the foregoing, the failure
or alleged failure of the Companies to pay, discharge and perform, from and
after Closing, all Liabilities of the Companies, in accordance with their
respective terms, or the failure or alleged failure of the Purchaser to (a) pay,
discharge and perform all US Liabilities, UK Liabilities and German Liabilities
in accordance with their respective terms, (b) to perform its obligations
pursuant to Section 5.1 of the UK Business Transfer Agreement, Section 6.6 of
the UK Business Transfer Agreement, Section 7.1 of the UK Business Transfer
Agreement and Section 7.2 of the UK Business Transfer Agreement (the "Purchaser
Payment Indemnification");

          (3)     any failure or alleged failure by the Purchaser to cause the
Companies, the US Business, the UK Business and the German Business to continue
the employment of all employees (including with respect to US employees,
employees taking advantage of the Family and Medical Leave Act of 1993) of the
Companies, the US Business, the UK Business and the German Business employed at
Closing, on comparable terms and conditions to those applicable to such
employment immediately prior to the Closing, and otherwise in accordance with
all applicable Laws and other obligations (the "Purchaser Employment
Indemnification");

and all such losses, assessments, Liabilities, claims, damages, costs and
expenses are referred to hereinafter as the "SELLERS' LOSSES."

          C.      SURVIVAL; LIMITATIONS. Notwithstanding anything else in this
Agreement or any Additional Transfer Document or Ancillary Agreement to the
contrary:

                  (i)    Except as set forth in Section 9.14(C)(vi), the
representations and warranties of the Seller and the Purchaser, respectively,
under this Agreement and any Additional Transfer Document or Ancillary
Agreement, and any indemnification obligations

                                      -56-
<Page>

arising therefrom, shall survive the Closing and shall expire and terminate on
the date which is 18 months following the Closing Date; PROVIDED, HOWEVER, that
the Sellers' representations and warranties in Section 3.1(B)(ii), and the
Purchaser's representations and warranties in Section 4.1(B)(ii), shall expire
and terminate upon the Closing. The covenants of the parties shall expire in
accordance with their terms, and the indemnification obligations of the
Purchaser or the Seller, respectively, on account of the Special Indemnification
Obligations (as defined in Section 9.14(C)(ii), below) shall continue in full
force and effect following Closing (provided that the time limit applicable to
indemnification obligations relating to Section 3.1(N), the Sellers' Tax
Payment Covenant, the Purchaser's Tax Payment Covenant and Article IV of the UK
Business Transfer Agreement, as the case may be, shall be as set forth in
Section 9.14(C)(vi)), in each case subject to the other limitations of this
Section 9.14.

                  (ii)   The Sellers shall not have any indemnification
obligations under Section 9.14(A) or otherwise under this Agreement, and the
Purchaser shall not have any indemnification obligations under Section 9.14(B)
or otherwise under this Agreement: (a) except to the full extent that the
Purchaser's Losses, or the Sellers' Losses, respectively, with respect to any
individual claim or any related claims arising from the same or substantially
similar factual circumstances, exceed $15,000 (a "MATERIAL CLAIM"), in which
event such indemnification shall be required to the extent of such Purchaser's
Losses or the Sellers' Losses, respectively, including such $15,000 amount
(subject also to the limitations provided in succeeding clauses (b) and (c) of
this Section 9.14(C)(ii)); (b) except to the extent that the Purchaser's Losses,
or the Sellers' Losses, respectively, with respect to all such Material Claims
in the aggregate exceed $500,000 (the "INDEMNIFICATION THRESHOLD"), in which
event such indemnification shall be required only to the full extent of the
Purchaser's Losses or the Sellers' Losses, respectively, in excess of the
Indemnification Threshold (subject also to the preceding clause (a) and the
succeeding clause (c) of this Section 9.14(C)(ii)); and (c) to the extent that
the Purchaser's Losses in the aggregate, or the Sellers' Losses in the
aggregate, respectively, exceed $15,000,000 (the "CAP"), in which event such
indemnification shall be required only to the extent of the Purchaser's Losses
or the Sellers' Losses, respectively, below the Cap (subject also to the
preceding clauses (a) and (b) of this Section 9.14(C)(ii)); provided, however
that neither the limitation to Material Claims set forth in clause (a), above,
nor the Basket nor the Cap, shall apply to:

                         (1)  the Seller's indemnification obligations with
     respect to the Dorset Environmental Matter pursuant to Section 9.14(A)(2);

                         (2)  the Sellers' Consent Indemnification, if
     applicable under Section 6.4;

                         (3)  the Sellers' indemnification obligations with
     respect to the Keystone Plans pursuant to Section 9.14(A)(3);

                         (4)  the Sellers' indemnification obligations pursuant
     to Section 9.14(A)(4), Section 9.14(A)(5) and Section 9.14(A)(6);

                                      -57-
<Page>

                         (5)  the Sellers' indemnification obligations with
     respect to its covenants or agreements in Section 5.2(P) and Section
     5.4(B),

                         (6)  the Sellers' indemnification obligations with
     respect to its covenants or agreements in Section 5.6(E), Section 5.6(F)
     and Section 5.6(G);

                         (7)  the Purchaser's indemnification obligations with
     respect to the Purchaser Payment Indemnification pursuant to Section
     9.14(B)(2)

                         (8)  the Purchaser's indemnification obligations with
     respect to the Purchaser Employment Indemnification pursuant to Section
     9.14(B)(3);

                         (9)  the Purchaser's indemnification obligations with
     respect to its agreements and covenants in Section 5.1(B) of this Agreement
     and Section 6.4 of the UK Business Transfer Agreement;

                         (10) the Purchaser's indemnification obligations with
     respect to its covenants or agreements under Section 8.2 of the UK Business
     Transfer Agreement;

                         (11) the Purchaser's indemnification obligations with
     respect to its covenants or agreements under Section 10.1 of the UK
     Business Transfer Agreement and Section 10.2 of the UK Business Transfer
     Agreement; and

                         (12) the Purchaser's indemnification obligations with
     respect to its covenants or agreements in Section 5.2(N), Section 5.2 (Q),
     Section 5.4(A), Section 5.4(B) and Section 5.6(D), and in the last sentence
     of Section 5.2(G), and in Article 4 (Tax Provisions) of the UK Business
     Transfer Agreement.

          The indemnification obligations which are described in the foregoing
     clauses (1) through (12), inclusive, are referred to as the "Special
     Indemnification Obligations."

                  (iii)  (a)  With respect to any matter for which
indemnification has been provided hereunder, the Indemnitee (as defined below)
hereby covenants and agrees to use all commercially reasonable efforts to
collect amounts payable to the Indemnitee under any applicable insurance policy
of the Indemnitee, and any such amounts so paid to the Indemnitee shall reduce
the indemnification obligations of the Indemnitor (as defined below) with
respect to such matters.

                         (b)  The amount of Sellers' Losses or Purchaser's
Losses shall be calculated taking into account (and reducing such Sellers'
Losses or Purchaser's Losses to reflect) the Tax benefits, if any, inuring to
any such Indemnitee, on account of such Indemnitee's incurring the losses,
assessments, Liabilities, claims, damages, costs or expenses (including
reasonable attorneys' fees and disbursements) giving rise to such Sellers'
Losses or Purchaser's

                                      -58-
<Page>

Losses, respectively; provided that such Tax benefits, if any, shall be as
reasonably determined by the Indemnitee.

                         (c)  The Purchaser shall not be entitled to make a
claim for indemnification under this Section 9.14 for any breach by any Seller
of any covenant, representation or warranty set forth in this Agreement if the
Purchaser had actual knowledge of such breach prior to or at the Closing;
provided that this 9.14(C)(iii)(c) shall not apply to the Special
Indemnification Obligations.

                  (iv)   In no event shall Sellers' Losses or Purchaser's
Losses, as the case may be, include amounts arising from consequential, special,
exemplary, or punitive damages; provided that with respect to the Special
Indemnification Obligations only, Sellers' Losses or Purchaser's Losses, as the
case may be, on account of such Special Indemnification Obligations may include
amounts arising from consequential damages.

                  (v)    In no event shall this Section 9.14 require duplicative
payments or indemnities by the Sellers (in the case of Purchaser's Losses) or
the Purchaser (in the case of Sellers' Losses).

                  (vi)   No claim for indemnification by the Purchaser on
account of the Sellers' breach of the Sellers' Tax Payment Covenant or of
Section 3.1(N), and no claim for indemnification by the Sellers on account of
the Purchaser's breach of the Purchaser's Tax Payment Covenant, may be made
after the 60th day following the expiration of the applicable statutes of
limitations with respect to the Taxes in question, giving effect to any
extension thereof, provided that in relation to any obligation of the Sellers
hereunder in respect of UK Tax, such obligation shall remain in force for a
period of six (6) years from the end of the accounting period in which Closing
occurred, and if the UK, US or German tax authorities allege fraud or negligence
in the preparation of a Tax Return there shall be no time limit on the Sellers'
obligations with respect to the Sellers' Tax Payment Covenant or Section 3.1(N).

                  (vii)  The Sellers shall have no liability under this
Agreement (including under Section 3.1(N), Section 5.2 and Section 9.14(A)) in
relation to any Liability or matter to the extent that: (a) such matter or
Liability was included in the determination of Closing Net Worth or falls within
one of the categories of assets or liabilities to be included in Closing Net
Worth; or (b) such matter or Liability arises by reference to an event occurring
on or prior to December 31, 2001 and an amount is provided for such matter or
Liability in the Financial Statements for the year ending on December 31, 2001,
provided the limitation on such liability shall be restricted solely to the
amount so provided in such Financial Statements; or (c) such matter or Liability
arises after December 31, 2001 and in the Ordinary Course of the Businesses; or
(d) such matter or Liability has been discharged prior to Closing (provided that
this clause (d) shall not apply to the extent such discharge would reasonably be
expected to result in a Material Adverse Effect or otherwise materially impairs
the future operations of the Businesses); provided that the foregoing clauses
(b) and (c) of this 9.14(C)(vii) shall not apply to the Special Indemnification
Obligations.

                                      -59-
<Page>

                  (viii) No Indemnitor (as defined below) shall have any
indemnification obligations with respect to the indemnification obligations
described in clauses (1), (2), (3), (4), (6), (8), and (9) of Section
9.14(C)(ii) except to the extent that the Purchaser's Losses or Seller's Losses,
as the case may be, of the Indemnitee (as defined below) with respect thereto
arise as the result of a claim asserted by a third party (including a
Governmental Entity) which is not the Indemnitee or an Affiliate of the
Indemnitee (and which claim does not result from the actions of the Indemnitee
or such Affiliate, and in this regard each of the Sellers and the Purchaser, as
Indemnitee, agrees that neither it nor its Affiliates will take any actions
reasonably likely to result in any such third party claim). For purposes of the
foregoing in this Section 9.14(C)(viii), the term "Affiliate" shall not include
any officer, director or employee acting in their individual capacities.

                  (ix)   The parties acknowledge that the limitations set forth
in the preceding clauses (i), (ii), (iii), (iv), (v), (vi), (vii), and (viii) of
this Section 9.14(C) are not mutually exclusive, but rather are separate and
independent limitations, and that each and all such limitations may, alone or
together, apply to a party's indemnification obligations in accordance with
their respective terms.

          D.      Notwithstanding anything herein to the contrary, each party's
sole and exclusive remedy against any other party for any breach of a
representation, warranty, covenant or other obligation made in or imposed by
this Agreement or any Additional Transfer Document, or otherwise in connection
with the Transfer of the Shares, the US Business, the UK Business or the German
Business or the other transactions contemplated hereunder or under the
Additional Transfer Documents shall be a claim for indemnification under this
Section 9.14, subject to all of the limitations of this Section 9.14, including
under Section 9.14(C).

          E.      PROCEDURES.

                  (i)    In the event that any Legal Proceeding shall be
instituted with respect to which indemnification may be sought by one party
hereto from another party under the provisions of this Section 9.14, the party
seeking indemnification ("INDEMNITEE") shall, promptly after acquiring knowledge
of such Legal Proceeding, cause written notice in reasonable detail of such
Legal Proceeding which is covered by this indemnification to be forwarded to the
other party from which indemnification is being sought ("INDEMNITOR"), provided,
however, the failure to notify the Indemnitor will not relieve the Indemnitor of
any liability it may have to indemnify the Indemnitee except to the extent that
the Indemnitor's defense of such action, or any of the Indemnitor's rights with
respect to the same, including any rights under insurance or against any third
parties, is actually prejudiced or impaired by the Indemnitee's failure to give
such notice.

                  (ii)   In the event of the initiation of any such Legal
Proceeding against an Indemnitee, the Indemnitor shall have the absolute right
after the receipt of the notice described iI Section 9.14(E)(i), at its option
and at its own expense, to be represented by counsel of its choice, and (subject
to Section 9.14(E)(iii)) to defend against, negotiate, settle or otherwise deal
with any Legal Proceeding or demand that relates to any Purchaser's Losses or
Sellers' Losses, as the case may be, indemnified against hereunder, and, in such
event, the Indemnitee

                                      -60-
<Page>

will reasonably cooperate with the Indemnitor and its representatives in
connection with such defense, negotiation, settlement or dealings; PROVIDED,
HOWEVER, that the Indemnitee may directly participate in any such Legal
Proceeding so defended with counsel of its choice at its own expense.

                  (iii)  Without the prior written consent of the Indemnitee,
which shall not be unreasonably withheld, the Indemnitor will not enter into any
settlement of any third party claim which would lead to Liability or create any
financial or other obligation on the part of the Indemnitee which is not paid or
reimbursed in full by the Indemnitor on account of its indemnification
obligation hereunder; provided, however, notwithstanding anything herein
provided to the contrary, Indemnitee may refuse to consent to a settlement which
imposes continuing obligations on Indemnitee or involves any non-monetary
relief, does not result in a complete release of Indemnitee from any and all
Liability or involves a finding or admission of any violation of Legal
Requirements or any violation of the rights of any Person by Indemnitee. If a
firm offer is made to settle a third party claim without leading to Liability or
the creation of a financial or other obligation on the part of the Indemnitee
for which the Indemnitee is not entitled to indemnification hereunder and the
Indemnitor desires to accept and agree to such offer, the Indemnitor will give
written notice to the Indemnitee to that effect. If the Indemnitee notifies the
Indemnitor that it does not consent to such firm offer within ten (10) Business
Days after its receipt of such notice from the Indemnitor, the Indemnitee may
continue to contest or defend such third party claim and, in such event, the
maximum Liability of the Indemnitor as to such third party claim will not exceed
the amount of such settlement offer, plus the Purchaser's Losses or Sellers'
Losses, as the case may be, reasonably paid or incurred by the Indemnitee
through the end of such 10-Business Day period.

                  (iv)   After any final judgment or award shall have been
rendered by a Governmental Entity of competent jurisdiction, and the time in
which to appeal therefrom has expired, or a settlement shall have been
consummated, or the Indemnitee and the Indemnitor shall have arrived at a
mutually binding agreement with respect to each separate matter alleged to be
indemnified against by the Indemnitor hereunder, the Indemnitee shall forward to
the Indemnitor notice of any sums due and owing with respect to such matter, and
the Indemnitor shall pay all of the sums so owing to the Indemnitee by wire
transfer or certified or bank cashier's check within thirty (30) days after the
date of such notice.

                  (v)    A claim for indemnification for any matter not
involving a third party claim may be asserted by notice to the party from whom
indemnification is sought.

     Section 9.15 SELLER AGENT. Each of the Sellers does hereby irrevocably
appoint SII as its agent and attorney-in-fact to act on behalf of such Seller
with respect to the sale and transfer of the Shares, the Assets, the US
Business, the UK Business and the German Business hereunder, to act on behalf of
each Seller in any litigation or arbitration involving this Agreement or the
transactions contemplated hereby, and to act on behalf of each Seller for
purposes of any and all communications with the Purchaser, and SII hereby
accepts such appointment. The Purchaser shall be entitled to rely without

     C.   CERTAIN INTERPRETIVE MATTERS. Unless the context otherwise requires,
(i) each accounting term not otherwise defined in this Agreement has the meaning
assigned to it in accordance with GAAP, (ii) "or" is disjunctive but not
necessarily exclusive, (iii) all words used in this Agreement will be construed
to be of such gender or number as the circumstances require, (iv) unless
otherwise expressly provided, the word "including" does not limit the preceding
words or terms and shall mean "including without limitation", (v) the words
"herein", "hereunder" and words of similar import shall refer to this Agreement,
(vi) all references to $ or dollar amounts mean lawful currency of the United
States of America. No provision of this Agreement will be interpreted in favor
of, or against, any of the parties hereto by reason of the extent to which any
such party or its counsel participated in the drafting thereof or by reason of
the extent to which any such provision is inconsistent with any prior draft
hereof or thereof.

     D.   DISCLOSURE SCHEDULES. The disclosure of any matter in any Disclosure
Schedule shall also qualify the representations and warranties contained in
Sections of this Agreement

                                      -66-
<Page>

other than the Section to which such Schedule specifically relates only to the
extent that it provides on its face a reasonable correlation to the subject
matter of such other Sections or otherwise provides a cross-reference to such
other Section (or to the Schedule specifically relating to such other Section).
Because of the different jurisdictions in which the Companies, the UK Business
and the German Business are located, and because of the different management
teams having day-to-day responsibility for the operations of the Companies, the
UK Business and the German Business, information contained in the Disclosure
Schedule was collected and is organized in separate sets included in the
Disclosure Schedule. Although the Sellers have endeavoured to prepare the
schedules comprising the Disclosure Schedule in a consistent manner, some of the
schedules differ in format or style according to local practice in the
jurisdictions where particular Companies, the UK Business and the German
Business are located. The disclosure of any matter in any schedule shall
expressly not be deemed to constitute an admission by the Sellers, or to
otherwise imply, that any such matter is material for the purposes of this
Agreement or that any other schedule (or set of schedules) is incomplete by
virtue of the omission of such disclosure.

4.   TAX PROVISIONS

     4.1    UK VAT

            4.1.1   The consideration for all supplies for VAT purposes made or
                    deemed to be made under or in connection with the sale of
                    the UK Assets under this agreement shall be deemed to be
                    exclusive of VAT. The party receiving the supply in question
                    shall pay to the party making that supply (in addition to
                    the consideration) all VAT which the party making the supply
                    is required to account for to HM Customs & Excise
                    ("Customs") in relation to that supply.

            4.1.2   For the purposes of this Section: "TOGC" means the transfer
                    of a business or part of a business as a going concern for
                    the purposes of section 49 of the Value Added Tax Act 1994
                    and article 5 of the Value Added Tax (Special Provisions)
                    Order 1995.

            4.1.3   P&G plc and the Purchaser believe that the sale of the UK
                    Assets will be treated as a TOGC and accordingly that the
                    sale will be neither a supply of goods nor a supply of
                    services for the purposes of the VAT Act with the
                    consequence that VAT will not be charged on the sale of the
                    UK Assets at Closing.

            4.1.4   P&G plc warrants to the Purchaser that it is registered for
                    VAT purposes under the VAT Act.

            4.1.5   The Purchaser warrants to P&G plc that: (i) it is registered
                    for VAT purposes under the VAT Act or immediately as a
                    result of this transaction will be a taxable person within
                    the meaning of section 3 of the VAT Act; (ii) it intends to
                    use the UK Assets for the same business as that previously
                    carried on by P&G plc in relation to those UK Assets; and
                    (iii) it is not purchasing the UK Assets as a nominee for
                    any other person.

            4.1.6   All VAT records relating to the UK Assets in respect of
                    periods prior to completion and which are required to be
                    preserved for any period after completion under the VAT Act
                    shall be transferred to the Purchaser.

            4.1.7   The party retaining the VAT records referred to above shall
                    procure that the same shall be preserved for such periods as
                    may be required by law and during such periods shall permit
                    the other party or its agents at all reasonable times and
                    subject to reasonable written notice to inspect and take
                    copies of such records at the cost of the party requesting
                    such inspection and/or copies.

            4.1.8   If it is determined that the sale of the UK Assets under
                    this Appendix A-2 does not constitute a TOGC, then the VAT

<Page>

                    chargeable by P&G plc to the Purchaser shall be paid upon
                    the later of within 5 business day of demand by P&G plc and
                    the day which falls 2 business days before the date upon
                    which such VAT becomes payable to HM Customs and Excise, and
                    any VAT records provided by P&G plc to the Purchaser shall
                    be returned to P&G plc.

     4.2    The consideration attributable to each of the UK Assets shall be
            determined and allocated in accordance with Section 5.2F of the
            Master Agreement.

5.   LIABILITIES UNDER CONTRACTS

            result of a breach of any of the UK Contracts or to the extent they
            are incurred by reason of or in connection with the non-performance,
            variation, termination (or the consequences of any such variation or
            termination) or the negligent or defective performance of the
            Contracts by the Purchaser).

6.   THIRD PARTY CONSENTS UNDER CONTRACTS

     6.1    To the extent that the benefit of any of the UK Contracts can be
            assigned by P&G plc to the Purchaser without any Third Party
            Consents, or relevant Third Party Consents have been obtained prior
            to Closing, this Agreement shall constitute an assignment of the
            relevant UK Contracts with effect from the Closing Date.

     6.2    If any Third Party Consent has not been obtained at or before
            Closing, the sale of the relevant UK Contract shall, notwithstanding
            Closing, be conditional on the relevant Third Party Consent.

     6.3    Where a Third Party Consent is required for the assignment of the
            benefit of, or novation, of, a UK Contract:

            6.3.1   this Agreement shall not constitute an assignment or
                    attempted assignment of the relevant UK Contract if the
                    assignment or attempted assignment would constitute a breach
                    of the UK Contract, and

            6.3.2   the Purchaser shall be responsible (at the expense of the
                    Purchaser) for obtaining, and shall use all reasonable
                    endeavours with the co-operation of P&G plc to obtain, any
                    Third Party Consent to assignment or novation of all
                    relevant UK Contracts after the Closing.

<Page>

            assigned or is not permitted to be assigned to the Purchaser except
            with a Third Party Consent, until the relevant Third Party Consent
            is obtained:

                    act, neglect, default or omission on the part of the
                    Purchaser to perform or comply with any such obligation of

     possession of the German Assets to the German Purchaser by physically
     handing over, or permitting the German Purchaser to take, such possession
     and, in respect of German Assets in the possession of third parties, by
     assigning to the German Purchaser all of Spirent GmbH's claims against such
     third parties for the surrender or return of the said German Assets. The
     German Purchaser purchases and accepts such transfer, assignment and
     delivery from Spirent GmbH.

(c)  Those assets, agreements, claims and rights that are not listed herein
     shall remain with Spirent GmbH unless they are unequivocally attributable
     to the German Assets.

(d)  In case there are any doubts arising as to the attribution of assets,
     agreements, claims and rights to the German Assets, Spirent GmbH and the
     German Purchaser shall endeavor to

                                       -4-
<Page>

     find a solution that is based on mutuality and Spirent GmbH shall respect
     the interests and needs of the German Purchaser in a favorable way.

(e)  To the extent provided in the Master Agreement, the German Purchaser hereby
     assumes and agrees to pay, honor and discharge all liabilities, obligations
     and commitments of Spirent GmbH of any nature, whether known or unknown,
     absolute, accrued, contingent or otherwise and whether due or to become
     due, arising out of the operations of the German Business on or before the
     Closing Date, including, but not limited to, (i) all liabilities and
     obligations under the German Leasing Agreements, or under other leases or
     contracts which the German Purchaser elects to accept and assume; (ii) all
     of Spirent GmbH's liabilities, obligations and commitments primarily
     related to or arising in connection with the German Business, and (iii) all
     liabilities and obligations relating to the German Business Employees
     (collectively the "GERMAN LIABILITIES").

(f)  Spirent GmbH and the German Purchaser agree that the employment agreements
     between Spirent GmbH and the German Business Employees are transferred to
     the German Purchaser either according to Section 613 a of the German Civil
     Code or pursuant to this Agreement; the German Purchaser hereby assumes all
     liabilities with respect to these German Business Employees. In case one
     or more of these German Business Employees object to such transfer and
     Spirent GmbH decides to terminate the employment with such objecting German
     Business Employees, the cost of such termination shall be borne by Spirent
     GmbH, including all severance payments, if any. Spirent GmbH and the German
     Purchaser shall coordinate their measures to inform the German Business
     Employees about this Agreement.

(g)  Nothing contained herein is intended to, nor shall it be construed to,
     alter or vary the terms and conditions set forth in the Master Agreement,
     which terms and conditions shall survive the execution and delivery of this
     Agreement. In the event of any inconsistency between the provisions of this
     Agreement and the Master Agreement, the provisions of the Master Agreement
     shall govern. For the avoidance of doubt, all provisions of the Master
     Agreement (including without limitation the representations, warranties,
     covenants and indemnification provisions of the Master Agreements) shall
     apply to the transfer of the German Business in the absence of any express
     provision to the contrary in this Agreement.

(h)  Notwithstanding anything to the contrary in this Agreement, this Agreement
     shall not constitute an agreement to assign or transfer any instrument,
     contract, lease, permit or other agreement or arrangement or any claim,
     right or benefit arising thereunder or resulting therefrom if an assignment
     or transfer or an attempt to make such an assignment or transfer without
     the consent of a third party would constitute a breach or violation thereof
     or affect adversely the rights of the German Purchaser or Spirent GmbH
     thereunder; and any transfer or assignment to the German Purchaser by
     Spirent GmbH of

                                       -5-
<Page>

     any interest under any such instrument, contract, lease, permit or other
     agreement or arrangement that requires the consent of a third party shall
     be made subject to such consent or approval being obtained. In the event
     any such consent or approval is not obtained on or prior to the Closing
     Date, each of Spirent GmbH and the German Purchaser shall continue to use
     all reasonable efforts to obtain any such approval or consent after the
     Closing Date until the later of such time as such consent or approval has
     been obtained and the first anniversary of the date hereof, and Spirent
     GmbH will co-operate with the German Purchaser in any lawful and
     economically feasible arrangement to provide that the German Purchaser
     shall receive the interest of Spirent GmbH, as the case may be, in the
     benefits under any such instrument, contract, lease or permit or other
     agreement or arrangement, including performance by Spirent GmbH, as the
     case may be, as agent, if economically feasible, PROVIDED that the German
     Purchaser shall undertake to pay or satisfy the corresponding liabilities
     for the enjoyment of such benefit to the extent the German Purchaser would
     have been responsible therefor hereunder if such consent or approval had
     been obtained. Nothing in the preceding sentence shall be construed to
     require any party or its Affiliates to pay, or commit to pay, any amount to
     (or incur any obligations in favor of) any Person from whom any such
     consent or approval may be required (other than nominal governmental filing
     fees). Nothing in this Section (g) shall be deemed a waiver by the German
     Purchaser of its right to have received on or before the Closing Date an
     effective assignment of all of the German Assets nor shall this Section (g)
     be deemed to constitute an agreement to exclude from the German Assets any
     assets described under Section (b).

(i)  This Agreement shall be binding upon and inure to the benefit of Spirent
     GmbH and the German Purchaser and their respective administrators,
     successors and assigns, PROVIDED that any assignment, by operation of law
     or otherwise, by any party (except as may be permitted by Section 9.3 of
     the Master Agreement) hereto shall require the prior written consent of the
     other party, and any purported assignment or other transfer without such
     consent shall be void and unenforceable.

(j)  The German Purchaser is liable for all transfer taxes in connection with
     the execution of this Agreement.

(k)  It is understood between the German Purchaser and Spirent GmbH that the
     sale of the German Business is, as a sale of business pursuant to Section 1
     section 1a Umsatzsteuergesetz, not subject to VAT (Umsatzsteuer). If the
     sale of the German Business turns out to be partly or in total subject to
     VAT (Umsatzsteuer) then the purchase price according to Section 5.2(F) of
     the Stock and Asset Purchase Agreement is deemed to be the net purchase
     price. In this case Spirent GmbH shall issue an invoice to the German
     Purchaser in accordance with Section 14 section 1 Umsatzsteuergesetz. The
     German Purchaser shall, assisted by Spirent GmbH, then assign in lieu of
     performance its claim for a VAT refund

                                       -6-
<Page>

     (Umsatzsteuererstattungsanspruch) against the German Internal Revenue
     Service (Finanzamt) pursuant to Section 46 Abgabenordnung.

(l)  After Closing, Spirent GmbH shall provide transitional services to the
     German Purchaser in accordance with Section 5.20 of the Master Agreement.

(m)  This Agreement may be executed in several counterparts. It shall be
     sufficient for the valid conclusion of this Agreement that each party
     hereto signs the counterpart delivered to the respective other party.

(n)  The Exhibits attached hereto shall constitute part of this Agreement. This
     Agreement shall be governed by and construed in accordance with the
     substantive laws of Germany, without giving effect to the principles of
     conflict of laws thereof.

(o)  The invalidity or enforceability of any provision of this Agreement shall
     not affect the validity or enforceability of any other provision of this
     Agreement, which shall remain in full force and effect. No delay or
     omission on the part of any party to this Agreement in exercising any
     right, power or remedy provided by law or under this Agreement or any other
     documents referred to in it shall impair such right, power or remedy or
     operate as a waiver thereof. The single or partial exercise of any right,
     power or remedy provided by law or under this Agreement shall not preclude
     any other or further exercise thereof or the exercise of any other right,
     power or remedy. The rights, powers and remedies provided in this Agreement
     are cumulative and not exclusive of any rights, powers and remedies
     provided by Law.

(p)  Any notice or other communication given or made under or in connection with
     the matters contemplated by this Agreement shall be in writing and shall be
     made in accordance with the terms as to notices set out in the Master
     Agreement.

(q)  Each of Spirent GmbH and the German Purchaser shall, at their own cost,
     from time to time, on being required to do so by the other party now or at
     any time in the future do or procure the carrying out of all such acts
     and/or execute or procure the execution of all such documents, in a form
     satisfactory to the requiring party, as the requiring party may reasonably
     consider necessary for vesting the German Business and the German Assets in
     the name of the German Purchaser and otherwise for giving full effect to
     this Agreement and securing to the requiring party the full benefit of the
     rights, powers and remedies conferred upon the requiring party in this
     Agreement.

IN WITNESS WHEREOF the parties have caused this Agreement to be executed by
their authorized representatives as of the date first set forth above.
