      A. The Shareholders hold directly all of the issued share capital of the
Company, excluding the Redemption Shares (as defined in Section 9.2).

      B. The Board of Directors of the Purchaser believes it to be in the best

Section 2.1(i)) which will, immediately after the Closing, be transferred to the
Company, free and clear of all Liens.

      D. Each of the Shareholders, as the holders in the aggregate, directly, of
all the issued share capital of the Company, excluding the Redemption Shares
(the "Company Shares"), wishes to sell and transfer to the Purchaser on the
terms and subject to the conditions set forth in this Agreement, all of such
share capital.

      E. Immediately prior to the Closing, the Purchaser shall (i) subscribe for
and purchase shares of the Company's capital (the "Subscription Shares") in an
aggregate subscription amount equal to (euro)1,116,612 (the "Subscription
Amount") for the purpose of redeeming the Redemption Shares and (ii) advance a
loan (the "New Loan") to the Company in an aggregate amount equal to
(euro)3,915,728 (the "New Loan Amount") for the purpose of discharging the
Shareholder Liabilities and the Borrowed Amount (each as defined herein).



      F. Concurrently with the execution and delivery of this Agreement,
Enterprise Ireland, as the holder of the Redemption Shares, has executed and
delivered to the Company a letter agreement in the agreed form (the "Enterprise
Ireland Agreement") pursuant to which Enterprise Ireland has agreed to consent,
among other provisions, to (i) the redemption of the Redemption Shares by the
Company for the aggregate amounts set forth in the Enterprise Ireland Agreement
(the "Redemption"), such Redemption to occur contemporaneously with the Closing;
(ii) the McKee Property Transfer (as defined in Section 2.29); and (iii) the
waiver of certain rights held by Enterprise Ireland, including the right to
repayment for certain incentive grants made to the Company. The agreements,
consents, and waivers set forth in the Enterprise Ireland Agreement are referred
to in their entirety as the "Enterprise Ireland Transactions."

      NOW THEREFORE, in consideration of the covenants, promises,
representations and warranties set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereby agree as follows:

                                    ARTICLE I

                   PURCHASE AND SALE OF COMPANY SHARE CAPITAL

      1.1 Purchase and Sale. Subject to the terms and conditions hereof, (i) the
Shareholders will sell, assign, transfer, and deliver the Company Shares to the
Purchaser with full title guarantee, free and clear of all Liens, and with the
benefit of all rights of whatsoever nature attaching or accruing to the Company
Shares, including rights to any dividends and distributions declared, paid, or
made by the Company in respect of such Company Shares on or after the date of
this Agreement, and (ii) the Purchaser will purchase the Company Shares from the
Shareholders at the Closing.

HUNDRED AND NINE EURO ((euro)14,358,909) (the "Cash Amount"), less any

therefrom under any applicable Legal Requirement (as defined in Section 9.2)
relating to Taxation (as defined in Section 2.10) (including the Code (as
defined in Section 9.2) or any requirement of the laws of Ireland relating to
Taxation). To the extent such amounts are so deducted or withheld, such amounts
shall be treated for all purposes under this Agreement as having been paid to
the Person to whom such amounts would otherwise have been paid.

            (b) The Purchaser acknowledges and agrees that the Purchaser shall
be solely and exclusively responsible for, and shall pay, all stamp duties and
similar Taxes relating to or resulting from the acquisition by the Purchaser of

Agreement where the Purchaser has any obligation to make payment to any or all
of the Shareholders, each of the Shareholders hereby authorizes the Purchaser to

sufficient evidence of payment and shall operate as a good discharge to the
Purchaser and who shall be obliged to see the appropriate application of such
payment among the Shareholders.

Documents (including the similar constituent documents of Finglas) or (ii) any
Contract, permit, concession, franchise, license, judgment, order, decree, or

any Shareholder (including any SCG Shareholder), or any other third party (so as
not to trigger any Conflict), is required by or with respect to a Group Company,
Finglas, any Shareholder (including any SCG Shareholder), or any other Sigma

Company Closing Documents or the consummation of the transactions contemplated
hereby and thereby (including, without limitation, the Acquisition, the Finglas
IP Transfer, the McKee Property Transfer, the Enterprise Ireland Transactions,
and the Amro Share Purchase), except as set forth on Schedule 2.5 of the Group

                                      -12-


consents, waivers, approvals, orders, authorizations, declarations, or filings
being referred to collectively herein as the "Required Consents").

      2.6 Company Financial Statements.

            (a) Attached as Schedule 2.6(a) of the Group Disclosure Letter are
true correct and accurate copies of the following financial statements:

                  (i) the audited balance sheets of the Company as at December
31, 2002, December 31, 2003, and December 31, 2004 (the "Company Balance
Sheets");

                  (ii) the audited balance sheet of Sigma UK as at December 31,
2004 (the "UK Balance Sheet");

                  (iii) the audited statements of income and/or loss of the
Company for the years ended December 31, 2002, December 31, 2003, and December
31, 2004 (the "Company Income Statements"); and

                  (iv) the audited statements of income/loss of Sigma UK for the
years ended December 31, 2004, December 31, 2003, and December 31, 2002 (the "UK
Income Statements").

      The Company Balance Sheets and the UK Balance Sheet are sometimes referred
to collectively herein as the "Group Balance Sheets." The Company Income
Statements and the UK Income Statements are sometimes referred to collectively
herein as the "Group Income Statements." The Group Income Statements and the
Group Balance Sheets are sometimes referred to collectively herein as the "Group
Financial Statements."

            (b) The Group Financial Statements have been prepared (i) in
accordance with and comply with all applicable Legal Requirements, including,
without limitation the Companies Acts and with respect to Sigma UK, the similar
legislation applicable in England and Wales; (ii) in conformity with Irish GAAP
or UK GAAP, as the case may require; and (iii) on a consistent basis with the
audited accounts of the Company and/or Sigma UK for the accounting periods
prescribed. The Group Financial Statements (i) present a true and fair view of
the assets and Liabilities of the Company or Sigma UK, as the case may require,
as of the respective dates of the Group Balance Sheets; (ii) present a true and
fair view of the profits and losses of the Company and Sigma UK, as the case may
require, for the periods shown in the Group Income Statements; (iii) contain
provision or reserve reasonably considered adequate at the date of their
preparation for bad or doubtful debts and depreciation on fixed assets; and (iv)
contain a note of all capital commitments of the Company and Sigma UK as of such
dates.

            (c) Attached as Schedule 2.6(c) to the Group Disclosure Letter are
true and correct copies of the unaudited monthly management accounts of each of
the Company and Sigma UK, consisting for each of a balance sheet as at May 29,
2005 and a profit and loss account for the period beginning on January 1, 2005
and ended on May 29, 2005 (the "Management Accounts"). The Management Accounts
were prepared in conformity with Irish GAAP or UK GAAP, as the case may require,
on a consistent basis with the Group Financial Statements. The profit and loss
accounts included in the Management Accounts truly and fairly

                                      -13-


present the results of operations of the Company or Sigma UK, as applicable, for
the periods presented, and the balance sheets contained in the Management
Accounts fairly and accurately present the assets and Liabilities of the Company
or Sigma UK, as applicable, as at the dates presented; provided, however, that
the Management Accounts are subject to normal recurring year-end audit
adjustments (which will not be material either individually or in the
aggregate). The "Management Balance Sheets" consists of the balance sheets dated
as at May 29, 2005 for each of the Company and Sigma UK, which are included in
the Management Accounts.

            (d) The books, records, and accounts of each Group Company
accurately and fairly reflect, in reasonable detail, the transactions in and
dispositions of the assets of such Group Company. The systems of internal
accounting controls maintained by each Group Company are sufficient to provide
reasonable assurances (i) that transactions are recorded as necessary to permit
preparation of financial statements in conformity with Irish GAAP or UK GAAP, as
the case may require, (ii) that receipts and expenditures are executed only in
accordance with the authorization of management, and (iii) regarding prevention
or timely detection of the unauthorized acquisition, use or disposition of such
Group Company's assets that could materially affect such Group Company's
financial statements.

            (e) Attached as Schedule 2.6(e) of the Group Disclosure Letter is a
true and correct copy of the Company's pro-forma unaudited combined statement of
income/loss for the twelve months ended December 31, 2004 (the "Pro Forma Income
Statement"). The Pro Forma Income Statement was prepared in good faith to
reflect the combined results of operations of the Company and Sigma UK for the
period stated, and the Pro Forma Income Statement presents a true and fair view
of such combined operating results for the period stated.

            (f) Schedule 2.6(f) of the Group Disclosure Letter provides an
accurate and complete breakdown of all amounts (including loans, advances,
receivables, or other indebtedness) owed to any Group Company by any current or
former director, officer, employee, or shareholder of any Group Company or any
Sigma Party or any affiliated Person thereof ("Affiliate Receivables"). All
Affiliate Receivables (including those receivables reflected in the Management
Accounts that have not yet been collected and those receivables that have arisen
since the date of the Management Balance Sheet and that have not yet been
collected) (i) represent valid obligations arising from bona fide transactions
entered into in the Ordinary Course of Business and (ii) are current and will be
collected in full when due, without any counterclaim or set-off.

            (g) Schedule 2.6(g) of the Group Disclosure Letter provides an

2004 and in excess of (euro)125,000 during the period from January 1, 2005 to
the date of this Agreement, in each case identifying the aggregate amount of
revenues recognized or received from such customer or other Person. For purposes
of

                                      -14-


the Closing, the Company shall update Schedule 2.6(h) for the period beginning
January 1, 2005 and ending on the Closing Date. The Company has delivered to the

Company and any customer or Person identified on Schedule 2.6(g).

            (i) Schedule 2.6(i) of the Group Disclosure Letter contains a
backlog report dated as of June 30, 2005 that sets forth a true and correct list
of all outstanding but unfilled orders for the Company's or Sigma UK's products

the product, the quantity ordered, and the per unit and gross sales price.

            (j) Intentionally Left Blank.

      2.7 Liabilities.

            (a) The Group Companies have no Liabilities except (i) Liabilities
set forth or fully reserved against in the Group Balance Sheets as at December

and prior to the date hereof in the Ordinary Course of Business, which in no
event exceed (euro)50,000 individually or (euro)3,000,000 in the aggregate; or
(iii) Liabilities incurred in the Ordinary Course of Business after the date
hereof in accordance with the terms of this Agreement.

            (b) Schedule 2.7(b) of the Group Disclosure Letter provides, and the
Final Balance Sheet Certificate will provide, an accurate and complete breakdown
of, and ageing for, (i) all accounts payable of the Group Companies in the case
of the execution and delivery of this Agreement, as of May 29, 2005 and in the
case of the Final Balance Sheet Certificate, as of the Closing Date; (ii) all
Liabilities of the Group Companies for borrowed money, in each case identifying
the amount owed, the identity of the party to whom funds are owed, and the
nature of the transaction under which the Liability was incurred, in the case of
the execution and delivery of this Agreement as of May 29, 2005 and in the case
of the Final Balance Sheet Certificate, as of the Closing Date; and (iii) all
other accrued Liabilities of the Group Companies, in each case identifying the
amount owed, the identity of the party to whom funds are owed, and the nature of
the transaction under which the Liability was incurred, in the case of the
execution and delivery of this Agreement as of May 29, 2005, and in the case of
the Final Balance Sheet Certificate, as of the Closing Date.

            (c) None of the Group Companies has effected or otherwise been
involved in any Off-Balance Sheet Arrangement (as defined in Section 9.2).
Without limiting the generality of the foregoing, no Group Company is or has
ever been a guarantor of any indebtedness, obligation, or Liability of any other
Person.

      2.8 Accounts Receivable. Schedule 2.8 of the Group Disclosure Letter
provides a complete and accurate list of all accounts receivable of the Group
Companies and sets forth for each (i) the identity of the party from whom the
receivable is collectible and the Group Company to which such receivable is
owed; (ii) when such receivable becomes due and the current ageing thereof; and
(iii) the amount of such receivable. All accounts receivable shown on Schedule
2.8 and/or the Management Balance Sheet (net of reserves indicated on the
Management Balance

                                      -15-


Sheet) or thereafter acquired until the Closing (net of reserves accrued in the
Ordinary Course of Business) will be collectible within 120 days of the date
recorded (subject to the Purchaser's using reasonable efforts after Closing to
collect the same). The values at which accounts receivable are carried on the
books of the Group Companies reflect the accounts receivable valuation policy of
the Company and are in accordance with Irish GAAP. None of the receivables of
the Group Companies is subject to any claim of recoupment, set off, or
counterclaim (whether asserted or unasserted), and, to the knowledge of each
Group Company and each of the Shareholders, there are no facts or circumstances
(whether asserted or unasserted) that would reasonably be expected to give rise
to any such claim. No accounts receivable of the Group Companies are contingent
upon the performance by any Group Company of any obligation. None of the Group
Companies has granted to any Person any Lien on any such receivables, and no
agreement for deduction or discount has been made with respect to any of such
receivables. Without limiting the foregoing, Finglas has no accounts receivable.

      2.9 Business Changes. Since December 31, 2004 (or such other date
specifically set out in this Section 2.9) to the date of this Agreement and
continuing through the Closing Date, except as otherwise contemplated by this
Agreement, each of the Group Companies and Finglas has conducted its business

            (b) There have been no changes in the financial condition, business,
prospects, net worth, assets, properties, operations, obligations or Liabilities
of any Group Company or Finglas which, individually or in the aggregate, have
resulted or could be expected (whether before or after the Closing) to result in
a Material Adverse Effect on such Group Company or Finglas.

            (c) No Group Company has issued, or authorized for issuance, any
equity security, bond, note or other security, or accelerated the vesting of any
employee stock benefits. No Group Company has granted or entered into any
commitment or obligation to issue or sell any such equity security, bond, note
or other security of any Group Company whether pursuant to offers, stock option
agreements, stock bonus agreements, stock purchase plans, incentive compensation
plans, warrants, calls, conversion rights, or otherwise.

            (d) None of the Group Companies or Finglas has paid any Liability or

proceeding, suit, or appeal, pending or threatened against it or any of its
assets or properties, except for current Liabilities included in the Group

                                      -18-


            (a) Definition of Taxes. For the purposes of this Agreement, "Tax,"

foreign, municipal or other taxes, assessments, and any other charges, duties,
impositions, and Liabilities of any governmental, supra-governmental or other

2.10(a) as a result of being a member of an affiliated, consolidated, combined,
or unitary group for any period; and (iii) any liability for the payment of any
amounts of the type described in clause (i) or (ii) of this Section 2.10(a) as a
result of any express or implied obligation to indemnify any other Person or as
a result of any obligations under any agreements or arrangements with any other
Person with respect to such amounts and including any Liability for taxes of a
predecessor entity.

            (b) Tax Returns and Audits.

                  (i) For purposes of this Agreement, "Tax Return" shall mean
any return (including any information return), report, statement, declaration,
estimate, schedule, notice, notification, form, election, certificate, or other
document or information filed with or submitted to, or required to be filed with
or submitted to, any Governmental Entity whether in Ireland, the United States,
the United Kingdom, Italy, France, or elsewhere in connection with the
determination, assessment, collection, or payment of any Tax or in connection
with the administration or enforcement of, or compliance with, any Legal
Requirement relating to Taxes.

                  (ii) Each Group Company has for each accounting period up to
and including the accounting period in which Closing falls accurately prepared
and properly and timely filed, taking into effect any extension of time within
which to file (the circumstances of such extensions being described in Schedule
2.10(b)(ii) of the Group Disclosure Letter) all required Tax Returns relating to
any and all Taxes concerning or attributable to such Group Company or its
operations, and such Tax Returns are true and correct and have been completed in
accordance with all applicable Legal Requirements.

                  (iii) All information required to be supplied to any
Governmental Entity whether in Ireland, the United States, the United Kingdom,
Italy, France, or elsewhere in connection with Taxes has been supplied or cause
to be supplied in a timely and proper manner. Each Group Company has duly and
properly submitted all claims, elections, amendments to

                                      -19-


claims, withdrawal of claims, and disclaimers which have been assumed to have
been made for the purpose of the Accounts within the time limits laid down in
the relevant legislation.

                  (iv) All such particulars, returns, notices, accounts, and
information described in this Section 2.10(b) have been correct in all material
respects.

            (c) Each Group Company has timely paid all Taxes it is required to
pay and has paid or withheld with respect to its employees and other third
parties all Taxes required to be paid or withheld (and has timely paid over any
withheld amounts to the proper Governmental Entity).

            (d) No Group Company is liable nor has at any time since the
Accounts Date been liable to pay interest on overdue Taxation.

            (e) As of the Accounts Date, no Group Company had any Liability in
respect of Taxes (whether actual or contingent) that was not fully provided for
in the Accounts. The amount of the deferred tax provision contained in the
Accounts was adequate as at the Accounts Date, the making and calculation of
such provision was fully in accordance with relevant generally accepted
accountancy practice as at the Accounts Date and no Group Company has
subsequently become aware of any reason why the deferred tax provision contained
in the Accounts may not be sufficient. All Taxes incurred by each Group Company
since the Accounts Date have arisen only from trading income of such Group
Company realized in the Ordinary Course of Business.

            (f) As of the Accounts Date, the Company has accumulated trading
corporation Tax losses of not less than (euro)6,850,000 available for carrying
forward, and nothing has occurred between the Accounts Date and the Closing Date
that will cause those losses to diminish. The Company has continued, and will
have continued at the Closing, to carry on the trade which gave rise to those
losses since the accumulation of those losses without any major change in the
nature or conduct of said trade and without any steps or arrangements which
could lead to such a major change in the nature or conduct of said trade.

            (g) Since the Accounts Date, (i) no accounting period of any Group
Company has ended or could be treated as having ended; (ii) no Group Company has
been involved in any transaction for which any Tax clearance has been sought or
obtained or could have been sought or obtained; (iii) no Group Company has
declared, made or paid any distribution within the meaning of TCA; (iv) there
has been no disposal of any asset (including trading stock) or supply of any
service or business facility of any kind (including a loan of money or the
letting, hiring or licensing of any property whether tangible or intangible) in
circumstances where the consideration actually received or receivable for such
disposal or supply was less than the consideration which could be deemed to have
been received for Tax purposes; (v) no event has occurred which will or may give
rise to a liability for Taxation on any Group Company where such liability would
be computed by reference to deemed income, profits, or gains or which will or
may give rise to a liability for Taxation on any Group Company where such
liability is directly or primarily chargeable against or attributable to another
Person; (vi) no Group Company has received a notice from any Tax, revenue or
fiscal authority or similar Governmental Entity which required or will or may
require such Group Company to withhold

                                      -20-


Tax from any payment actually made since the Accounts Date or which is likely to
be or may be made after the Closing Date; and (vii) save in the ordinary course
of trade as reflected in the Accounts, no Group Company has made any payment or
become obligated to make any payment which will not be deductible when
calculating trading profits for the purposes of corporation Tax.

            (h) There is no dispute, disagreement, claim or Legal Proceeding
outstanding with respect to any Group Company in respect of any Tax and no such
dispute, disagreement, claim or Legal Proceeding is expected or contemplated or
likely to commence, and no reasonable basis exists for any such dispute,
disagreement, claim or Legal Proceeding regarding any Liability or potential
Liability to any Tax or regarding the availability of any relief from Tax. There
are no Liens for Taxes upon any of the assets of any Group Company. No Tax
Return of any Group Company has ever been examined or audited by any
Governmental Entity. No Group Company is, nor has ever been, a party to or bound
by any Tax indemnity agreement, Tax sharing agreement, Tax allocation agreement
or any similar agreement or Contract relating to Taxes.

            (i) Each Group Company is resident for Tax purposes in the
jurisdiction in which it is incorporated, has not been at any time resident for
Tax purposes in any other jurisdiction, has never carried on any trade in any
other jurisdiction (whether through a branch, agency, permanent establishment,
or otherwise), and has not at any time paid or been required to pay Tax on
income, profits, or grants to any Tax, revenue, or fiscal authority or similar
Governmental Entity in any other jurisdiction.

            (j) Every document in the possession of or under the control of any
Group Company or which affords any right or rights to such Group Company has
been duly and properly stamped, and no Group Company has an outstanding
Liability for stamp duty or capital duty or other similar Tax or interest or
penalties relating to stamp duty or capital duty. No Group Company has been
involved in any transaction involving any instrument in relation to which a
claim for exemption from stamp duty or other similar Tax was made.

            (k) Each Group Company has for each accounting period up to and
including the accounting period in which Closing falls sufficient and proper
records relating to past events, including any claims or elections made to
calculate the Tax liability or relief that would arise on any disposal or on the
realization of any asset owned by such Group Company at the Accounts Date or
acquired by such Group Company since the Accounts Date but before the Closing
Date. In the seven years prior to the Accounts Date, the amount of any Tax
liability of each Group Company has not, to any material extent, depended on any
arrangement or concession (in either case whether formal or informal) with any
Tax, revenue or fiscal authority or similar Governmental Entity. Each Group
Company is in material compliance with all terms and conditions of any Tax
exemptions, claims, elections or reliefs it has applied for or obtained from any
Tax, revenue or fiscal authority or similar Governmental Entity, and the
execution of this Agreement will not have any adverse effect on the continued
validity and effectiveness of any such Tax exemptions, claims, elections or
reliefs.

            (l) The tax written down value of all plant and machinery owned by
the Company as at the Accounts Date is not less than (euro)831,980 and (other
than the mere passing of

                                      -21-


time) nothing has occurred since the Accounts Date that would reduce this
figure. If each asset acquired by any Group Company since the Accounts Date was
disposed of for a consideration equal to the consideration paid by such Group
Company on acquisition, then no Liability for Tax would arise to the relevant
Acquired Company in respect of the disposal of that asset.

            (m) In respect of the accounting period for the 1999 fiscal year,
the Company has filed a valid claim for rollover relief in respect of a disposal
of goodwill in 1999. The base cost for the purposes of Tax or chargeable gains
in all of the assets held by the Company at Closing which were involved in the
rollover claim is not less than (euro)1,618,012 and Schedule 2.10(m) of the
Group Disclosure Letter contains a list of all such assets with a schedule of
their base cost for the purposes of Tax on chargeable gains.

            (n) In respect of all dividends paid, each Group Company has fully
and correctly complied with the provisions of Chapter 8A of Part 6 of TCA or any
comparable foreign provision, and each Group Company has deducted and accounted
for all appropriate dividend withholding Tax and has no outstanding Liability in
respect of dividend withholding Tax. In respect of all dividends paid by each
Group Company, which were exempt from dividend withholding Tax, such Group
Company has received a declaration, in the form prescribed in Schedule 2A to TCA
or other comparable foreign provision, from the recipients of such dividends,
evidencing that dividend withholding tax was not payable.

            (o) No Group Company has been involved in any tax avoidance
transaction within the meaning of Section 811 of TCA or any other comparable
foreign provision. No Group Company has been involved in any transactions
falling within Part 33 of TCA. No Group Company has entered into or taken any
steps the object of which is a transaction which comes or might come within
Section 817 TCA or any comparable foreign provision. No Group Company has
acquired or disposed of any asset, supplied or received any service or entered
into any transaction otherwise than by way of bargain at arm's length. The trade
carried on by any Group Company has not at any time qualified for relief under
Part 14 TCA or any comparable foreign provision.

            (p) No Group Company is nor ever has been a member of a group of
companies within the meaning of Section 590, Section 616 of TCA or Part 12
Chapter 5 of TCA or any comparable foreign provision.

            (q) The entry into and consummation of this Agreement and the
transactions contemplated hereby, including the Closing, the Acquisition, the
Finglas IP Transfer, the McKee Property Transfer, the Redemption and the Amro
Share Purchase, will not give rise to a Tax Liability for any Group Company.

            (r) No Group Company has entered into any transaction which, if it
ceased to be associated with any company or ceased to be a member of a group of
companies for tax purposes, would give rise to a Tax Liability.

            (s) No Group Company has ever had, in respect of any accounting
period, any excess of distributable investment or estate income within the
meaning of Section 434 TCA. In respect of each Group Company, no loan or advance
or payment has been made or consideration

                                      -22-


given or transaction effected falling within Sections 438 or 439 TCA. No Group
Company has ever incurred any expense or paid any amount in consequence of which
that Group Company has been or could be treated under Sections 436 or 437 TCA,
as having made a distribution.

            (t) No obligation has arisen or will arise on or prior to Closing
for the Purchaser to deduct an amount under Section 980 TCA.

            (u) Finglas is in material compliance with all Legal Requirements
relating to Taxation, and Finglas has no outstanding Liability relating to
Taxation that would adversely affect in any manner the Finglas IP Transfer and
the transactions contemplated thereby.

            (v) VAT

                  (i) Each Group Company is a registered and taxable person for
the purposes of the Value Added Tax Act 1972 or any comparable foreign
legislation, as applicable, and has complied in all respects with such
legislation and all regulations made or notices issued thereunder and has
maintained full complete correct and up to date records, returns, invoices and
other documents (as the case may be) appropriate or requisite for the purposes
hereof.

                  (ii) No arrangement exists or has existed whereby for the
purposes of VAT legislation whether in Ireland, the United States, the United
Kingdom, Italy, France, or elsewhere the business activities of any Group
Company are or were deemed to be carried on by any other person or the business
activities of any other person are or were deemed to be carried on by any Group
Company.

                  (iii) No Group Company has at any time acted as an agent of
any person not established in Ireland within the meaning of Section 37 of the
Value Added Tax Act 1972.

                  (iv) Finglas has no Liability relating to VAT.

                  (v) All VAT groups of which a Group Company was a member prior
to the Closing are fully compliant in all respects with all Legal Requirements
relating to VAT, including without limitation, all filing requirements and
payment or reclaim requirements.

            (w) Sigma UK is a company whose business consists wholly or mainly
of the carrying on of a trade or trades within the meaning of Section 626B TCA
and is, by virtue of the law of the United Kingdom, resident for the purposes of
tax in the United Kingdom, and the Company is or was within the period of two
years ending on Closing, the parent company of Sigma UK within the meaning of
Section 626B TCA.

            (x) No agent of any Group Company constitutes or has ever
constituted a permanent establishment of the Group for Tax purposes other than
in the jurisdiction of incorporation of such Group Company.

      2.11 Restrictions on Business Activities. There is no Contract
(non-competition, field of use, "most favored nation," or otherwise), judgment,
injunction, order, or decree to which any Group Company or Finglas or any
Shareholder is a party, or otherwise binding on any Group

                                      -23-


Company or Finglas or any Shareholder, which has or could be expected to have
the effect of prohibiting or impairing any business practice of any Group
Company, any acquisition of property (whether tangible or intangible) by any
Group Company, or the conduct of business by any Group Company. Without limiting
the foregoing, none of any Group Company, Finglas, or any Shareholder is (i)
restricted from selling, licensing, or otherwise distributing any products or
services to any class of customers, in any geographic area, during any period of
time, or in any segment of the market or (ii) is required to offer or sell any
products or services to any Person on terms that are not less favorable than the
terms under which such products or services may be offered or sold to other
parties.

      2.12 Title of Properties; Absence of Liens; Condition of Equipment

            (a) No Group Company owns the freehold of any real property, nor has
any Group Company ever owned the freehold of any real property. Schedule 2.12(a)
of the Group Disclosure Letter sets forth a list of all real property (the
"Properties") currently leased or which will be leased to any Group Company, the
name of the lessor, the date of the lease and each amendment thereto, the
aggregate annual rental and/or other monies payable under any such lease. The
operations of the Group Companies, as the case may require, on the Properties do
not violate any applicable Legal Requirement, including, without limitation, any
applicable building regulation, planning requirement, planning act or other
statute. There is not, under any of such leases, any existing default or event
of default, or, to the knowledge of each Group Company and each of the
Shareholders, any event or circumstance which could reasonably be expected to
give rise to any default or event of default. The Company or Sigma UK, as the
case may be, is the sole occupier of the Properties and sole beneficial owner of
its interests in the Properties, and no lease, underlease, license, or other
agreement exists permitting other Persons to use or occupy the Properties.

            (b) The Group Companies have good and valid title to, or, in the
case of leased properties and assets, valid leasehold interests in, all of their
respective tangible properties and assets, real, personal and mixed, used or
held for use in its business, free and clear of any Lien except (i) as reflected
in the Group Financial Statements, (ii) for Liens created by the lessors of such
properties or assets, and (iii) for Liens for Taxes not yet due and payable. For
purposes solely of this Section 2.12(b) as it relates to the Properties, "good
and valid title" shall mean only such matters as relate to the title to the
Properties as short leaseholds in the context of a conveyancing transaction and
shall not include any matters relating to the condition of the Properties.

            (c) All equipment owned or leased by the Group Companies is listed
in Schedule 2.12(c) of the Disclosure Letter, specifically identifying the Group
Company owning or leasing such property, and except individual pieces of
equipment owned by the Company or Sigma UK with an individual book value of less
than (euro)10,000. All machinery, equipment, fixtures and vehicles owned,
leased, or used by the Group Companies are in good operating condition taking
into account their age, except for ordinary wear and tear, and are in a
reasonable state of repair and condition for the purposes for which they are
being used.

      2.13 Inventory

                                      -24-


            (a) Schedule 2.13(a) (the "Inventory Schedule") sets forth a
complete and accurate listing of all inventory, merchandise, finished goods, raw
materials, work-in-process, packaging and parts inventory of the Group Companies
as of the close of business on July 1, 2005 (the "Inventory" or "Inventories").
Finglas holds no Inventory. At the Closing, the Inventory Schedule shall be
updated to reflect the Inventory as of the Closing Date (such inventory, the
"Closing Inventory" and such updated Inventory Schedule, the "Closing Statement
of Inventory"). The Closing Statement of Inventory shall set forth a complete
and accurate list of all Closing Inventory. Subject to such write-downs to net
realizable value as shall be identified on the Inventory Schedule or the Closing
Statement of Inventory, as the case may require, the Inventory has been, and the
Closing Inventory will be, valued at the lower of cost price or market value on
a first in, first out basis.

            (b) The Inventory consists and the Closing Inventory will consist of
a quantity and quality usable in the Ordinary Course of Business of the Group
Companies, except for items of below-standard quality or obsolete items, all as
have been reflected on the Inventory Schedule or the Closing Statement of
Inventory, as applicable. The quantities of Inventory are reasonable in the
present circumstances of the Group Companies. A Group Company has good and
marketable title to all Inventories, and will have good and marketable title to
all Closing Inventories, free and clear of all Liens. The Inventories do not
consist and the Closing Inventory will not consist of any item held on
consignment. No Group Company is or will be under an obligation or Liability
with respect to accepting returns of items of Inventory or Closing Inventory or
any other merchandise, other than in the Ordinary Course of Business. No
clearance or extraordinary sale of the Inventories has been conducted, other
than in the Ordinary Course of Business.

            (c) Since January 1, 2005, each Group Company has manufactured,
inspected, tested and maintained all of the Inventory, and will have
manufactured, inspected, tested and maintained all Closing Inventory, in the
Ordinary Course of Business, and based on such operations, no Group Company has
experienced any issues associated with product defects or qualities that differ
materially from prior experience.

            (d) All inventories are located at the Group Address.

                                      -26-


            (b) Schedule 2.14(b) of the Group Disclosure Letter lists all
Registered Intellectual Property Rights owned by, filed in the name of, or
applied for by any Group Company or Finglas (the "Company Registered
Intellectual Property Rights") and lists any proceedings or actions before any
Governmental Entity (including the United States Patent and Trademark Office
(the "PTO") or equivalent authority anywhere in the world) related to any of the
Company Registered Intellectual Property Rights or Company Intellectual
Property.

            (c) Each item of Company Registered Intellectual Property Rights is
valid and subsisting, and all necessary registration, maintenance, and renewal
fees in connection with such Company Registered Intellectual Property Rights
have been paid and all necessary documents and certificates in connection with
such Company Registered Intellectual Property Rights have been filed with the
relevant Patent, Copyright, Trademark, or other authorities in the United
States, United Kingdom, Ireland, or any foreign jurisdictions, as the case may
be, for the purposes of obtaining, maintaining, perfecting, preserving or
renewing such Registered Intellectual Property Rights. There are no actions that
must be taken by any Group Company or Finglas within one hundred twenty (120)
days of the Closing Date, including the payment of any registration,
maintenance, or renewal fees, or the filing of any responses to PTO office
actions (or the actions of any other Governmental Entity in the United States or
elsewhere anywhere in the world), documents, applications, or certificates for
the purposes of obtaining, maintaining, perfecting, or preserving or renewing
any Registered Intellectual Property Rights. In each case in which any Group
Company or Finglas has acquired ownership of any Technology or Intellectual
Property Right from any person, such Group Company or Finglas, as the case may
be, has obtained a valid and enforceable assignment sufficient to irrevocably
transfer all rights in such Technology and the associated Intellectual Property
Rights (including the right to seek past and future damages with respect
thereto) to such Group Company or Finglas. To the maximum extent provided for
by, and in accordance with, applicable Legal Requirements, such Group Company or
Finglas, as the case may be, has recorded each such assignment of a Registered
Intellectual Property Right assigned to such Group Company or Finglas with the
relevant Governmental Entity, including the PTO, the U.S. Copyright Office, or
their respective equivalents in any relevant foreign jurisdiction, as the case
may be. Except as set forth on Schedule 2.14(c) of the Group Disclosure Letter,
no Group Company or Finglas has claimed a particular status, including "Small
Business Status," in the application for any Intellectual Property Rights, which
claim of status was not at the time made, or which has since become, inaccurate
or false or that will no longer be true and accurate as a result of the Closing.
There are no Intellectual Property Rights owned or used by any Group Company or
Finglas capable of registration which have not been so registered or in respect
of which application for registration has not been made and is pending.

            (d) None of any Group Company, Finglas, or any Shareholder has any
knowledge of any facts or circumstances that would render any Company
Intellectual Property invalid or unenforceable. Without limiting the foregoing,
none of any Group Company, Finglas, or any Shareholder knows of any information,
materials, facts or circumstances, including any information or fact that would
constitute prior art, that would render any of the Company Registered
Intellectual Property Rights invalid or unenforceable, or that would adversely
affect any pending application for any Company Registered Intellectual Property
Right, and none of any Group Company, Finglas, or any Shareholder has
misrepresented, or failed to disclose, or has any knowledge of any
misrepresentation or failure to disclose, any fact or circumstance in

                                      -27-


any application for any Company Registered Intellectual Property Right that
would constitute fraud or a misrepresentation with respect to such application
or that would otherwise affect the validity or enforceability of any Company
Registered Intellectual Property Right.

            (e) Each item of Company Intellectual Property is in full force and
effect, and is and will be after giving effect to the Finglas IP Transfer, free
and clear of any Liens. A Group Company or Finglas is, and immediately after the
Closing, a Group Company will be, the exclusive owner or exclusive licensee of
all Company Intellectual Property.

            (f) All Company Intellectual Property will be fully transferable,
alienable or licensable by a Group Company or the Purchaser following the
Closing without restriction and without payment of any kind to any third party.

            (g) To the extent that any Company Intellectual Property has been
developed or created by a third party for any Group Company or Finglas, such
Group Company or Finglas has a written agreement with such third party with
respect thereto, and such Group Company or Finglas either (i) has obtained
ownership of, and is the exclusive owner of (by operation of law or by valid
assignment, to the fullest extent it is legally possible to do so), or (ii) has
obtained a license (sufficient for the conduct of its business as currently
conducted and as proposed to be conducted) to, all such third party's
Intellectual Property Rights in such Technology. Any such agreements, licenses,
or assignments are fully assignable to the Company or Finglas, as the case may
require, without any requirement to obtain any consent or approval or any waiver
from any third party, and all such agreements, licenses, or assignments will
have been assigned and transferred to the Company on or prior to the Closing.

            (h) Except for Commercial Software Rights, all Technology used in or
necessary to the conduct of the business of any Group Company as presently
conducted or currently contemplated to be conducted by any Group Company was (1)
written and created solely by either (i) employees of such Group Company acting
within the scope of their employment or (ii) by third parties who have validly
and irrevocably assigned all of their rights, including Intellectual Property
Rights therein, to such Group Company, or (2) licensed to the Group Company
pursuant to a license on Schedule 2.14(h) of the Group Disclosure Letter, and no
third party owns or has any rights to any of the Company Intellectual Property.

            (i) All employees of each Group Company and Finglas have entered
into a valid and binding written agreement with such Group Company or Finglas,
as the case may require, sufficient to vest title in such Group Company, of all
Technology, including all accompanying Intellectual Property Rights, created by
such employee in the scope of his or her employment with such Group Company.

            (j) Each Group Company and Finglas has taken all steps that are
reasonably required to protect its respective rights in confidential information
and trade secrets of such Group Company or Finglas or provided by any other
Person to such Group Company or Finglas. Without limiting the foregoing, each
Group Company and Finglas has, and enforces, a policy requiring each employee,
consultant and contractor to execute a proprietary information, confidentiality
and assignment agreement, substantially in the form(s) attached hereto as
Schedule 2.14(j) of the Group Disclosure Letter, and all current and former
employees,

                                      -28-


consultants and contractors of each Group Company and Finglas have executed such
an agreement. No disclosure has been made to any other Person other than the
Purchaser of any know-how, or the financial or trade secrets of any Group
Company or Finglas except properly and in the Ordinary Course of Business and on
the basis that such disclosure is to be treated as being of a confidential
nature. No Group Company or Finglas has allowed any Company Intellectual
Property to lapse or enter into the public domain. No Group Company or Finglas
makes use of information confidential to a third party except under valid
licenses from such third parties, all of which are in full force and effect and
are listed on Schedule 2.14(h) of the Group Disclosure Letter. All know-how is
adequately documented and to the extent that the know-how is confidential or
important to the manufacture of products offered by the Group Companies or the
provision of the manufacture of products offered by the Group Companies, no part
of the same has been or will be disclosed to any third party by any Group
Company or Finglas or any of their respective officers, directors, employees, or
agents.

            (k) No Person who has licensed Technology or Intellectual Property
Rights to a Group Company or Finglas has ownership rights or license rights to
improvements made by such Group Company or Finglas in such Technology or
Intellectual Property Rights.

            (l) No Group Company or Finglas has transferred ownership of, or
granted any exclusive license of or right to use, or authorized the retention of
any exclusive rights to use or joint ownership of, any Technology or
Intellectual Property Right that is or was Company Intellectual Property, to any
other Person.

            (m) Schedule 2.14(m)-1 of the Group Disclosure Letter lists all
Contracts to which a Group Company or Finglas is a party (including, without
limitations, Contracts among the Group Companies and Finglas) with respect to
any Technology or Intellectual Property Rights (other than Commercial Software
Rights), including, without limitation, under which any Group Company or Finglas
has been granted or provided any Technology or Intellectual Property Rights by
third parties. Schedule 2.14(m)-2 of the Group Disclosure Letter lists all
Contracts to which a Group Company or Finglas is a party (including, without
limitations, Contracts among the Group Companies and Finglas) with respect to
any Technology or Intellectual Property Rights under which any Group Company or
Finglas has granted or provided any Technology or Intellectual Property Rights
to third parties. Neither of any Group Company or Finglas is in breach of, nor
has it failed to perform under, any of the foregoing Contracts and, to the
knowledge of each Group Company and each of the Shareholders, no other party to
any such license or Contract is in breach thereof or has failed to perform
thereunder.

            (n) Schedule 2.14(n) of the Group Disclosure Letter lists Contracts
between a Group Company or Finglas, on the one hand, and any other Person, on
the other hand, or among the Group Companies and Finglas, wherein or whereby
such Group Company or Finglas has agreed to, or assumed, any obligation or duty
to warrant, indemnify, reimburse, hold harmless, guaranty or otherwise assume or
incur any obligation or Liability or provide a right of rescission with respect
to the infringement or misappropriation by such Group Company or Finglas or such
other Person of the Intellectual Property Rights of any Person other than a
Group Company or Finglas.

                                      -29-


            (o) There are no Contracts between a Group Company or Finglas, on
the one hand, and any other Person, on the other hand, or among the Group
Companies and Finglas, with respect to Company Intellectual Property under which
there is, to each Group Company's knowledge or the knowledge of any Shareholder,
any dispute regarding the scope of such Contract, or performance under such
Contract, including with respect to any payments to be made or received by such
Group Company or Finglas thereunder. Neither of any Group Company nor Finglas is
or will be as a result of the execution and delivery of this Agreement or the
performance by a Group Company, Finglas, or any Shareholder of their respective
obligations hereunder, in violation of any license, sublicense, or Contract
relating to Company Intellectual Property (including Contracts among the Group
Companies and Finglas).

            (p) The operation of the businesses of each Group Company as
currently conducted or as contemplated to be conducted by such Group Company,
including but not limited to the design, development, use, import, branding,
advertising, promotion, marketing, manufacture and sale of the products,
Technology or services (including products, Technology or services currently
under development) of such Group Company, does not, will not, and will not when
conducted by the Purchaser in substantially the same manner following the
Closing, infringe or misappropriate any Intellectual Property Right of any
Person, violate any right of any Person (including any right to privacy or
publicity) or constitute unfair competition or trade practices under the laws of
any jurisdiction, and no Group Company nor any of the Shareholders has received
notice from any Person claiming that such operation or any act, product,
technology or service (including products, Technology or services currently
under development) of any Group Company infringes or misappropriates any
Intellectual Property Right of any Person or constitutes unfair competition or
trade practices under the laws of any jurisdiction (nor does any Group Company
or any Shareholder have knowledge of any basis therefor).

            (q) To the knowledge of each Group Company and each Shareholder, no
Person is infringing or misappropriating any Company Intellectual Property
Right.

            (r) No Company Intellectual Property or product or service of any

decree, order, judgment or settlement agreement or stipulation that restricts in
any manner the use, transfer or licensing thereof by such Group Company or
Finglas or that may affect the validity, use or enforceability of such Company
Intellectual Property.

            (s) No (i) product, Technology, service, or publication of any Group
Company or Finglas, (ii) material published or distributed by any Group Company
or Finglas, or (iii) conduct or statement of any Group Company or Finglas
constitutes a defamatory statement or material or false advertising or otherwise
violates in any material respect any Legal Requirement.

cost, to execute or procure to be done and executed all such further acts,

U.S. GAAP. Such exchange rate shall remain applicable in future periods with
respect to Revenue previously calculated and reported as of any prior Fiscal
Quarter End Date (such that no adjustments shall be made on any subsequent
Fiscal Quarter End Date with respect to the determination of the amount of
cumulative Revenue as of any prior Fiscal Quarter End Date).

            (c) Calculation and Payment.

                  (i) The Shareholders shall not be entitled to receive any
Earnout Payment unless and until cumulative Revenue for the Earnout Period
exceeds Base Revenue.

                  (ii) At such time as the amount of cumulative Revenue exceeds
Base Revenue and until such time as cumulative Revenue exceeds Target Revenue,
the Shareholders

                                      -59-


shall be entitled to receive, and the Purchaser shall pay to the Shareholders on
each Earnout Payment Date an aggregate amount, if any, determined by subtracting
(A) the aggregate Earnout Payments, if any, made pursuant to this Section
5.21(c)(ii) for any prior portion of the Earnout Period from (B) the product of
the Earnout Quotient and the Base Earnout Target. The "Earnout Quotient" shall
mean the squared amount (i.e., x(2)) of the Quota Percentage, and the "Quota
Percentage" shall mean the amount determined by dividing (A) the amount by which
cumulative Revenue as of the most recent Fiscal Quarter End Date exceeds Base
Revenue by (B) NINE MILLION EURO ((euro)9,000,000). Notwithstanding the
foregoing, in no event shall the Purchaser be obligated to make Earnout Payments
pursuant to this Section 5.21(c)(ii) (i) totaling in the aggregate more than the
Base Earnout Target; (ii) with respect to cumulative Revenue less than or equal
to Base Revenue or in excess of the Target Revenue; or (iii) except as
specifically set forth in proviso (ii) of the definition of "Revenue," with
respect to any Revenue actually recognized in any period before the beginning or
after the termination of the Earnout Period.

                  (iii) In the event that cumulative Revenue exceeds Target
Revenue, the Shareholders shall be entitled to receive and the Purchaser shall
pay to the Shareholders on each Earnout Payment Date an aggregate amount, if
any, determined by subtracting (A) the aggregate Earnout Payments made pursuant
to this Section 5.21(c)(iii) for any prior portion of the Escrow Period from (B)
the product of 0.58333 and the amount by which cumulative Revenue as of the most
recent Fiscal Quarter End Date exceeds Target Revenue. Notwithstanding the
foregoing, in no event shall the Purchaser be obligated to make Earnout Payments
pursuant to this Section 5.21(c)(iii) (i) totaling in the aggregate more than
the Bonus Earnout Target; (ii) with respect to cumulative Revenue less than or
equal to Target Revenue; or (iii) except as specifically set forth in proviso
(ii) of the definition of "Revenue," with respect to any Revenue actually
recognized in any period before the beginning or after the termination of the
Earnout Period.

                  (iv) The Purchaser shall pay Earnout Payments, if any, to the
Shareholders based on the proportion specified on the Schedule of Shareholders
under the caption "Allocation Percentage" not later than the applicable Earnout
Payment Date.

                  (v) Notwithstanding any other provision of this Section 5.21,
in no event shall the Purchaser be obligated to make Earnout Payments (i)
totaling in the aggregate more than the Maximum Earnout Payment; (ii) with
respect to cumulative Revenue less than or equal to Base Revenue; or (iii)
except as specifically set forth in proviso (ii) of the definition of "Revenue,"
with respect to Revenue actually recognized in any period before the beginning
or after the termination of the Earnout Period.

            (d) Audit Right. Each Earnout Payment under this Section 5.21, if
any, shall be accompanied by a written computation showing in reasonable detail
the basis on which the payment was calculated, consistent with the requirements
of this Agreement. The Shareholder Representative may, within 30 days following
receipt of such written computation, request in writing an audit of the
calculations used to determine the amount of the Earnout Payment. Following
delivery of such request, and upon no less than 15 days prior written notice,
the Shareholder Representative may cause an independent public accountant to
audit the records of the Purchaser reasonably related to the calculation of such
Earnout Payment. Such audit shall be conducted during the Purchaser's normal
business hours. The fees charged by such independent public accountant in
connection with such audit shall be paid (i) by the Shareholders in the event

                                      -60-


the applicable deficiency, if any, is less than five percent (5%) of all Earnout
Payments made by the Purchaser and (ii) by the Purchaser in the event any
deficiency exceeds five percent (5%) of such amounts. Within 10 days following
completion of the audit, the Purchaser shall pay to the Shareholders any
deficiency discovered during the audit; provided that if there is any dispute
regarding the computation of the payment, the matter shall be referred to
arbitration in accordance with the provisions of Section 6.3(g) of this
Agreement.

            (e) Conduct of the Business. The Purchaser shall use its good faith
efforts during the Earnout Period to market and sell the Products; provided,
however, that the Purchaser's obligation under this section shall be subject in
all respects to the prudent business judgment of the Purchaser's management in
connection with the business and operations of the Purchaser and its
subsidiaries (including the Company) taken as a whole.

      5.22 Non-competition; Non-solicitation. From the date of this Agreement
and for a period of twenty-four months thereafter, SCG will not, and SCG will
cause its affiliate entities not to,

            (a) be engaged in or concerned or interested (except as the holder
or beneficial owner for investment purposes of not more than 10% in nominal
value of any class of securities listed or dealt with on any recognized stock
exchange or automated quotation system) at one or more locations within Ireland,
the UK, Western Europe and Israel, any business which is of the same or similar
type to the Restricted Business which is carried on by the Company, its
subsidiaries and/or associated companies or which is in competition with the
Restricted Business of the Company and/or or its subsidiaries and/or its
associated companies;

            (b) solicit the services of or engage, whether on its own behalf or
on behalf of others, any Person who is a manager and/or employee of any Group
Company on the Closing Date (excluding the Transferred Employees); or

            (c) solicit the services of or engage, whether on its own behalf or
on behalf of others, any Person who is or was a customer of any Group Company at
any time during the 12 month period immediately preceding the date of this
Agreement with respect to any matter relating to the Restricted Business.

      5.23 Intellectual Property Contracts. On or before the tenth Business Day
following the Closing Date, the Shareholders shall have procured and delivered
to the Purchaser (i) a duly executed consultancy agreement in a form reasonably
acceptable to the Purchaser between the Company and each of the Persons
identified on Annex D of the Agreement Annexes and (ii) an assignment and
transfer to the Company, free and clear of all Liens and in a form reasonably
acceptable to the Purchaser, of certain Intellectual Property Rights from Axicom
Limited. The obligations and covenants of the Shareholders pursuant to this
Section 5.23 are referred to herein as the "Intellectual Property Transfer
Covenants."

      5.24 Intentionally Left Blank.

                                   ARTICLE VI

                                      -61-


                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES;
                           INDEMNIFICATION AND ESCROW

      6.1 Survival of Representations, Warranties, and Covenants. The
representations, warranties, covenants, and agreements of the Shareholders
contained in this Agreement, the Company Closing Documents, or in any
certificate or other instruments delivered pursuant to this Agreement or the
Company Closing Documents, shall survive for a period of twelve (12) months
following the Closing Date (other than covenants that would by their terms
survive for a longer period); provided, however, that (i) the representations
and warranties contained in Section 2.4 (Company Capital Structure), Section 2.5
(Authority), Section 2.10 (Tax and Other Returns and Reports), Section 2.14
(Intellectual Property), Section 2.21 (Environmental Matters), Section 2.29
(Transfer of McKee Avenue Property; Other Pre-Closing Transactions; No
Liability), and the Title Warranties set forth in Article IIA; (ii) the
covenants of the Shareholders set forth in Section 1.3(f), Section 5.16 and
Section 5.17, and the Intellectual Property Transfer Covenants; and (iii) the
indemnities in respect of Wage Claims at Section 6.2(iii), Pension Scheme
Expenses at Section 6.2(iv), Transferring Employee Losses at Section 6.2(v),
Pre-Closing Taxes at Section 6.2(vi), and Specialty Liability Losses at Section
6.2(viii) (the representations, warranties and covenants set forth in the
foregoing subsections (i), (ii), and (iii) being referred to as "Special Loss
Warranties, Covenants, and Indemnities") shall survive until the shorter of (a)
six (6) years following the Closing Date and (b) the expiration of the date 90
days after the expiration of the applicable statute of limitations, and (ii) in
the case of fraud or willful and knowing misrepresentation or willful and
knowing breach, such representations, warranties, covenants, and agreements
shall survive indefinitely. The expiration of such twelve (12) month or longer
period, as applicable, is referred to as the "Survival Period." Neither the
Survival Period nor the Liability of any Indemnifying Party (as defined below)
shall be reduced by any investigation made at any time by or on behalf of the
Purchaser. If a written notice of claim pursuant to this Article VI has been
given prior to the end of the Survival Period by the Purchaser, then the
relevant representations, warranties, covenants, and agreements shall continue
to survive as to such claim until the claim has been finally resolved. The
representations and warranties of the Purchaser contained in this Agreement, or
in any certificate or other instrument delivered pursuant to this Agreement,
shall terminate on February 28, 2007.

      6.2 Indemnification. Each of the Shareholders (each, an "Indemnifying
Party" and collectively, the "Indemnifying Parties") shall indemnify and hold
the Purchaser and its officers, directors, and affiliates (the "Indemnified
Parties"), harmless against all claims, losses, Liabilities, damages,
deficiencies, costs and expenses, including reasonable attorneys' fees and
expenses of investigation and defense (hereinafter individually a "Loss" and
collectively "Losses") incurred or sustained by the Indemnified Parties, or any
of them, directly or indirectly, as a result of (i) any breach or inaccuracy of
a representation or warranty of any Shareholder contained in this Agreement, any
Company Closing Document, or in any certificate or other instrument delivered
pursuant to this Agreement or Company Closing Document (in any case, without
giving effect to any limitation as to "materiality," "Material Adverse Effect"
or similar qualification set forth therein); (ii) any failure by any Shareholder
to perform or comply with any covenant applicable to any of them contained in
this Agreement; (iii) any claims by any Person who is or was an employee,
director, or consultant of a Group Company for (A) retroactive wage increase
obligations or (B) mandatory wage increases during the first twelve (12) months
following the Closing Date, in either case that are in excess of the obligations
set forth in Annex

                                      -62-


E of the Agreement Annexes and which result from (a) union demands for wage
increases related to past concessions and/or (b) rulings by the Irish Labour
Relations Commission relating to the current National Wage Agreement, Sustaining
Progress (collectively, the "Wage Claims"); (iv) any Pension Scheme Expenses;
(v) any Transferring Employee Losses; (vi) any Pre-Closing Taxes; and (vii) any
Liability of the Company relating to any Borrowed Amount or Shareholder
Liability that is not satisfied at the Closing (the "Special Liability Losses").

      6.3 Escrow Arrangements.

            (a) Escrow Fund. By virtue of this Agreement and as security for the
indemnity provided for in Section 6.2 hereof, promptly after the Closing, the
Purchaser will deposit the Escrow Amount with the Escrow Agent, without any act
of any Shareholder, to constitute an escrow fund (the "Escrow Fund") to be
governed by the terms set forth herein. The Escrow Fund shall be available to
compensate the Indemnified Parties for any claims by such parties for any Losses
suffered or incurred by them and for which they are entitled to recovery under
this Article VI (subject to the Purchaser's obligation to take all commercially
reasonable good faith efforts to mitigate any such Losses, provided that the
Purchaser shall not be required to take any action that the Purchaser determines
in good faith is not in the best interests of the business of the Purchaser, the
Company, and their respective subsidiaries, taken as a whole).

            (b) Losses Threshold. Notwithstanding any provision of this
Agreement to the contrary, and except as set forth in the second sentence of
this Section 6.3(b), the Indemnified Parties may not recover any Losses under
Section 6.3(a) unless and until one or more Officer's Certificates identifying
such Losses under Section 6.3(a) in excess of ONE HUNDRED FIFTY THOUSAND EURO
((euro)150,000.00) in the aggregate (the "Losses Threshold") has or have been
delivered to the Escrow Agent and the Shareholder Representative as provided in
Section 6.3(e) hereof, and such Losses are (i) agreed to as recoverable by the
Shareholder Representative; (ii) not subject to an Objection Notice, validly
delivered in accordance with the provisions of Section 6.3(f) hereof (including
the time limitations set forth therein); or (iii) determined to be subject to
indemnification pursuant to Section 6.3(g) hereof, in which case the Indemnified
Parties shall be entitled to recover all Losses so identified (without regard to
the Losses Threshold). Notwithstanding the foregoing, the Losses Threshold shall
not apply with respect to Losses arising from or related to any breach of the
Special Loss Warranties, Covenants, and Indemnities, provided that such Losses
shall also not count against the Losses Threshhold for purposes of determining
whether such Losses Threshhold has been met. For the purposes hereof, "Officer's
Certificate" shall mean a certificate signed by any officer of the Purchaser:
(i) stating that an Indemnified Party has paid, sustained, incurred, or properly
accrued, or reasonably anticipates that it will have to pay, sustain, incur, or
accrue Losses, and (ii) specifying in reasonable detail the individual items of
Losses included in the amount so stated, the date each such item was paid,
sustained, incurred, or properly accrued, or the basis for such anticipated
Liability, and the nature of the misrepresentation, breach of warranty or
covenant to which such item is related.

            (c) Escrow Period; Distribution of Remaining Escrow Funds. Subject
to the following requirements, the Escrow Fund shall be in existence immediately
following the Closing and shall terminate at 5:00 p.m., local time in London,
England, on the first Business Day falling on or after the first anniversary of
the Closing Date (the "Escrow Period"); provided, however, that the Escrow
Period shall not terminate with respect to any amount which, in the

                                      -63-


reasonable judgment of the Purchaser, is necessary to satisfy any unsatisfied
claims specified in any Officer's Certificate delivered to the Escrow Agent and
the Shareholder Representative prior to the Escrow Period termination date. As
soon as all such claims have been resolved, the Escrow Agent shall deliver to
the Shareholders the remaining portion of the Escrow Fund together with accrued
interest thereon, if any, not required to satisfy such claims.

            (d) Protection of Escrow Fund.

                  (i) The Escrow Agent shall hold and safeguard the Escrow Fund
during the Escrow Period, shall treat such fund as a trust fund in accordance
with the terms of this Agreement and not as the property of any Indemnified
Party or any Indemnifying Party, and shall hold and dispose of the Escrow Fund
only in accordance with the terms of this Article VI.

                  (ii) The parties hereto agree that, for United States federal
income tax purposes, the Shareholders shall be the record owner of the Escrow
Fund until all amounts held in the Escrow Fund are distributed in accordance
with this Agreement. The Shareholders shall be responsible for any Taxes due
with respect to any interest or other earnings on the Escrow Fund.

                  (iii) During the term of this Agreement, the Escrow Fund shall
be invested and reinvested by the Escrow Agent in accordance with the specific
written instructions by the Purchaser and the Shareholder Representative from
time to time. Investments pursuant to such investment instructions described
above shall in all instances be subject to availability (including any
time-of-day requirements). In no instance shall the Escrow Agent have any
obligation to provide investment advice of any kind. The Escrow Agent shall be
authorized at all times and from time to time to liquidate any investment of the
Escrow Agent as may be necessary to provide available cash to make any release,
disbursement or payment called for under the terms of this Agreement. The Escrow
Agent shall have no responsibility or liability for any losses resulting from
liquidation of the Escrow Fund (such as liquidation prior to maturity).

                  (iv) The Escrow Agent shall be responsible for reporting, if
required, to the Internal Revenue Service any disbursements from the Escrow Fund
to the Shareholders. In the event the Escrow Agent is required by any applicable
Legal Requirement (as in effect at any time during the Escrow Period) to
withhold any amounts with respect to the payment of such interest or other
earnings on the Escrow Fund, the Escrow Agent shall give prior notice to the
Shareholders of the amounts required to be so withheld and the reasons therefor.

            (e) Claims for Indemnification.

                  (i) Upon receipt by the Escrow Agent at any time on or before
the last day of the Escrow Period of an Officer's Certificate, the Escrow Agent
shall, subject to the provisions of Section 6.3(f), Section 6.3(g) and Section
6.5 hereof, deliver to the Purchaser, as promptly as practicable, the portion of
the remaining Escrow Amount, if any, held in the Escrow Fund equal to such
Losses identified in such Officer's Certificate.

                  (ii) If the Shareholder Representative does not object in
writing within the sixty (60) day period after delivery by the Purchaser of the
Officer's Certificate as set forth in

                                      -64-


Section 6.3(f) below, such failure to so object shall be an irrevocable
acknowledgment by the Shareholder Representative and the Shareholders that the
Indemnified Party is entitled to the full amount of the claim for Losses set
forth in such Officer's Certificate.

                  (iii) Notwithstanding the foregoing or any contrary provision
of this Article VI, the Escrow Agent shall reimburse the Purchaser promptly for
all Pension Scheme Expenses with no requirement that the Escrow Agent or the
Purchaser obtain any consent or acknowledgement from the Shareholder
Representative or any Indemnifying Party, provided that (i) the aggregate amount
of Pension Scheme Expenses may not exceed (euro)75,000 and (ii) the Purchaser
has delivered to the Escrow Agent and the Shareholder Representative a written
request for such reimbursement together with a description in reasonable detail
of the nature and amount of Pension Scheme Expenses incurred.

            (f) Objections to Claims against the Escrow Fund. Following delivery
of any Officer's Certificate to the Escrow Agent, the Escrow Agent shall deliver
a duplicate copy of such certificate to the Shareholder Representative, and for
a period of sixty (60) days after such delivery, the Escrow Agent shall, except
as set forth in Section 6.3(e)(iii), make no delivery to the Purchaser of any
Escrow Amount pursuant to Section 6.3(e) hereof unless the Escrow Agent shall
have received written authorization from the Shareholder Representative to make
such delivery. After the expiration of such sixty (60) day period, subject to
the limitations set forth below, the Escrow Agent shall make delivery of that
portion of the Escrow Amount from the Escrow Fund equal to the amount of Losses
claimed in the Officer's Certificate, provided that no such payment or delivery
may be made if the Shareholder Representative shall object in a written
statement to the claim made in the Officer's Certificate (an "Objection
Notice"), and such Objection Notice shall have been delivered to the Escrow
Agent prior to the expiration of such sixty (60) day period. Any objection
Notice shall concurrently be delivered by the Shareholder Representative to the
Purchaser.

            (g) Resolution of Conflicts; Arbitration.

                  (i) In case the Shareholder Representative delivers an
Objection Notice in accordance with Section 6.3(f) hereof, the Shareholder
Representative and the Purchaser shall attempt in good faith to agree upon the
rights of the respective parties with respect to each of such claims. If the
Shareholder Representative and the Purchaser should so agree, a memorandum
setting forth such agreement shall be prepared and signed by both parties and,
in the case of a claim against the Escrow Fund, shall be furnished to the Escrow
Agent. The Escrow Agent shall be entitled to rely on any such memorandum and
make distributions from the Escrow Fund in accordance with the terms thereof.

                  (ii) If no such agreement can be reached after good faith
negotiation and within thirty (30) days after delivery of an Objection Notice,
either the Purchaser or the Shareholder Representative may demand arbitration of
the matter unless the amount of the Loss is at issue in pending litigation with
a third party, in which event arbitration shall not be commenced until such
amount is ascertained or both parties agree to arbitration, and in either such
event the matter shall be settled by arbitration conducted by three arbitrators.
The Purchaser and the Shareholder Representative shall each select one
arbitrator, and the two arbitrators so selected shall select the third
arbitrator, each of which arbitrators shall be

                                      -65-


independent and have at least ten (10) years relevant experience. The
arbitrators shall set a limited time period and establish procedures designed to
reduce and the cost and time for discovery while allowing the parties an
opportunity, adequate in the sole judgment of the arbitrators, to discover
relevant information from the opposing parties about the subject matter of the
dispute. The arbitrators shall rule upon motions to compel or limit discovery
and shall have the authority to impose sanctions, including attorneys' fees and
costs, to the same extent as a competent court of law or equity, should the
arbitrators determine that discovery was sought without substantial
justification or that discovery was refused or objected to without substantial
justification. The decision of a majority of the three arbitrators as to the
validity and amount of any claim in such Officer's Certificate shall be binding
and conclusive upon the parties to this Agreement, and notwithstanding anything
to the contrary in Section 6.3(f) hereof, the Escrow Agent shall be entitled to
act in accordance with such decision and make or withhold payments out of the
Escrow Fund in accordance therewith. Except with respect to claims related to
actions by a third party, such decision shall be written and shall be supported
by written findings of fact and conclusions that shall set forth the award,
judgment, decree, or order awarded by the arbitrators.

                  (iii) Any such arbitration shall be held in London, England
under the AAA International Commercial Arbitration Rules and Supplemental
Procedures for Large Complex Disputes ("AAA Rules"). The arbitrator(s) shall
determine how all expenses relating to the arbitration shall be paid, including
without limitation, the respective expenses of each party, the fees of each
arbitrator and the administrative fee of the American Arbitration Association.

                  (iv) Judgment upon any award rendered by the arbitrator(s) may
be entered in any court having jurisdiction. The foregoing arbitration provision
shall apply to any dispute among the Indemnifying Parties and an Indemnified
Party under this Article VI, whether relating to claims upon the Escrow Fund or
to the other indemnification obligations set forth in this Article VI.

            (h) Third-Party Claims.

                  (i) If any third party shall notify the Purchaser of any
matter (hereinafter referred to as a "Third Party Claim"), which the Purchaser
reasonably believes may result in a demand against the Escrow Fund or for other
indemnification pursuant to this Article VI, then the Purchaser shall give
written notice to the Shareholder Representative of any such Third Party Claim
or of facts upon which any such Third Party Claim will be based; provided,
however, that no delay or failure on the part of the Purchaser in notifying the
Shareholder Representative shall relieve the Shareholder Representative and the
Shareholders from any obligation hereunder unless the Shareholder Representative
and the Shareholders are thereby materially prejudiced (and then solely to the
extent of such prejudice).

                  (ii) In case any Third Party Claim is asserted against an
Indemnified Party, and the Purchaser notifies the Shareholder Representative
thereof pursuant to Section 6.3(h)(i) herein, the Shareholder Representative and
the Shareholders will be entitled, if the Shareholder Representative so elects
by written notice delivered to the Purchaser within

                                      -66-


fifteen (15) days after receiving the Purchaser's notice, to assume the defense
thereof, at the expense of the Shareholders, independent of the Escrow Fund if:

                        (A) the Purchaser has reasonably determined that Losses
which may be incurred as a result of the Third Party Claim do not exceed either
individually, or when aggregated with all other Third Party Claims, the total
dollar value of the Escrow Fund then available to satisfy the indemnification
obligations of the Indemnifying Parties;

                        (B) the Third Party Claim involves only money damages
and does not seek an injunction or other equitable relief;

                        (C) settlement of, or an adverse judgment with respect
to, the Third Party Claim is not, in the good faith judgment of the Purchaser,
likely to establish a precedential custom or practice adverse to the continuing
business interests of the Purchaser, any Group Company, or any of their
respective subsidiaries or other affiliates; and

                        (D) counsel selected by the Shareholder Representative
is reasonably acceptable to the Purchaser.

If the Shareholder Representative and the Shareholders so assume any such
defense, the Shareholder Representative and the Shareholders shall conduct the
defense of the Third Party Claim actively and diligently. The Shareholder
Representative and the Shareholders shall not compromise or settle such Third
Party Claim or consent to entry of any judgment in respect thereof without the
prior written consent of the Purchaser, which consent the Purchaser will not
unreasonably withhold, provided that the Purchaser may withhold such consent at
its sole and absolute discretion if (A) the amount of the proposed settlement,
together with any other pending claims for Losses, would exceed the amount then
available in the Escrow Fund; (B) the proposed settlement provides for any
remedy or obligation or covenant other than payment of money damages; or (C) the
Purchaser determines in good faith that the proposed settlement is likely to
establish a precedential custom or practice adverse to the continuing business
interests of the Purchaser or any of its subsidiaries or affiliates (including
any Group Companies).

                  (iii) In the event that the Shareholder Representative assumes
the defense of the Third Party Claim in accordance with Section 6.3(h)(ii)
above, the Indemnified Parties may retain separate counsel and participate in
the defense of the Third Party Claim, but the fees and expenses of such counsel
shall be at the expense of the Purchaser unless the Purchaser shall reasonably
determine that there is a material conflict of interest between or among the
Indemnified Parties and the Shareholder Representative and the Shareholders with
respect to such Third Party Claim, in which case the reasonable fees and
expenses of such counsel will be borne by the Shareholder Representative and the
Shareholders out of the Escrow Fund. The Indemnified Parties will not consent to
the entry of any judgment or enter into any settlement with respect to the Third
Party Claim without the prior written consent of the Shareholder Representative.
The Purchaser will cooperate in the defense of the Third Party Claim and will
provide reasonable access to documents, assets, properties, books, and records
reasonably requested by the Shareholder Representative and material to the claim
and will make available all officers, directors, and employees reasonably
requested by the Shareholder Representative for investigation, depositions, and
trial.

                                      -67-


                  (iv) In the event that (i) the Shareholder Representative
fails or elects not to assume the defense of the Indemnified Parties against
such Third Party Claim, which Shareholder Representative had the right to assume
under Section 6.3(h)(ii) above, or (ii) the Shareholder Representative is not
entitled to assume the defense of the Indemnified Parties against such Third
Party Claim pursuant to Section 6.3(h)(ii) above, the Indemnified Parties shall
have the right to undertake the defense, consent to the entry of any judgment or
enter into any settlement with respect to the Third Party Claim in any manner
they may deem appropriate (and the Indemnified Parties need not consult with, or
obtain any consent from, the Shareholder Representative in connection
therewith); provided, however, that except with the written consent of the
Shareholder Representative, no settlement of any such claim or consent to the
entry of any judgment with respect to such Third Party Claim shall alone be
determinative of the validity of a claim against the Escrow Fund. In each case,
the Indemnified Parties shall conduct the defense of the Third Party Claim
actively and diligently, and the Shareholder Representative and the Shareholders
will cooperate with the Indemnified Parties in the defense of that claim and
will provide reasonable access to documents, assets, properties, books and
records reasonably requested by the Indemnified Parties and material to the
claim and will make available all individuals reasonably requested by the
Indemnified Parties for investigation, depositions, and trial.

            (i) Escrow Agent's Duties.

                  (i) The Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions which the Escrow Agent may
receive after the date of this Agreement which are signed by an officer of the
Purchaser and the Shareholder Representative, and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed to be genuine and to have been signed or presented by the proper party
or parties. The Escrow Agent shall not be liable for any act done or omitted
hereunder as Escrow Agent while acting in good faith and in the exercise of
reasonable judgment, and any act done or omitted pursuant to the advice of legal
counsel shall be conclusive evidence of such good faith.

                  (ii) The Escrow Agent is hereby expressly authorized to
disregard any and all warnings given by any of the parties hereto or by any
other person, excepting only orders or process of courts of law or the
arbitrators pursuant to Section 6.3(g), and is hereby expressly authorized to
comply with and obey orders, judgments or decrees of any court or such
arbitrators. In case the Escrow Agent obeys or complies with any such order,
judgment or decree of any court or arbitrator, the Escrow Agent shall not be
liable to any of the parties hereto or to any other Person by reason of such
compliance, notwithstanding any such order, judgment, or decree being
subsequently reversed, modified, annulled, set aside, vacated, or found to have
been entered without jurisdiction.

                  (iii) The Escrow Agent shall not be liable in any respect on
account of the identity, authority or rights of the parties executing or
delivering or purporting to execute or deliver this Agreement or any documents
or papers deposited or called for hereunder.

                                      -68-


                  (iv) The Escrow Agent shall not be liable for the expiration
of any rights under any statute of limitations with respect to this Agreement or
any documents deposited with the Escrow Agent.

                  (v) In performing any duties under this Agreement, the Escrow
Agent shall not be liable to any party for damages, losses, or expenses, except
for gross negligence or willful misconduct on the part of the Escrow Agent. The
Escrow Agent shall not incur any such liability for (A) any act or failure to
act made or omitted in good faith or (B) any action taken or omitted in reliance
upon any instrument, including any written statement or affidavit provided for
in this Agreement that the Escrow Agent shall in good faith believe to be
genuine, nor will the Escrow Agent be liable or responsible for forgeries,
common law fraud, impersonations, or determining the scope of any representative
authority. In addition, the Escrow Agent may consult with legal counsel in
connection with performing the Escrow Agent's duties under this Agreement and
shall be fully protected in any act taken, suffered, or permitted by him/her in
good faith in accordance with the advice of counsel. The Escrow Agent is not
responsible for determining and verifying the authority of any person acting or
purporting to act on behalf of any party to this Agreement.

                  (vi) The parties and their respective successors and assigns
agree jointly and severally to indemnify and hold Escrow Agent harmless against
any and all losses, claims, damages, liabilities, and expenses, including
reasonable costs of investigation, counsel fees, including allocated costs of
in-house counsel and disbursements that may be imposed on Escrow Agent or
incurred by Escrow Agent in connection with the performance of his/her duties
under this Agreement, including but not limited to any litigation arising from
this Agreement or involving its subject matter, other than those arising out of
the gross negligence or willful misconduct of the Escrow Agent (the "Agent
Indemnification Expenses") as follows: fifty percent (50%) to be paid by the
Purchaser and fifty percent (50%) to be paid by the Shareholders; provided,
however, that in the event the Shareholders fail to timely pay such portion of
the Agent Indemnification Expenses, the parties agree that the Purchaser may at
its option pay such portion of the Agent Indemnification Expenses and recover an
equal amount (which shall be deemed a Loss) from the Escrow Fund.

                  (vii) The Escrow Agent may resign at any time upon giving at
least 30 days' written notice to the Purchaser and the Shareholder
Representative; provided, however, that no such resignation shall become
effective until the appointment of a successor escrow agent which shall be
accomplished as follows: the Purchaser and the Shareholder Representative shall
use their commercially reasonable efforts to mutually agree on a successor
escrow agent within thirty (30) days after receiving such notice. If the parties
fail to agree upon a successor escrow agent within such time, the Escrow Agent
shall have the right to appoint a successor escrow agent authorized to do
business in the State of Illinois. The successor escrow agent shall execute and
deliver an instrument accepting such appointment and it shall, without further
acts, be vested with all the estates, properties, rights, powers, and duties of
the predecessor escrow agent as if originally named as escrow agent. Upon
appointment of a successor escrow agent, the Escrow Agent shall be discharged
from any further duties and liability under this Agreement.

            (j) Fees. All fees of the Escrow Agent for performance of its duties
hereunder shall be paid by the Purchaser in accordance with the standard fee
schedule of the

                                      -69-


Escrow Agent. It is understood that the fees and usual charges agreed upon for
services of the Escrow Agent shall be considered compensation for ordinary
services as contemplated by this Agreement. In the event that the conditions of
this Agreement are not promptly fulfilled, or if the Escrow Agent renders any
service not provided for in this Agreement but that has been requested by an
officer of the Purchaser, or if the parties request a substantial modification
of the terms of the Agreement, or if any controversy arises, or if the Escrow
Agent is made a party to, or intervenes in, any litigation pertaining to the
Escrow Fund or its subject matter, the Escrow Agent shall be reasonably
compensated for such extraordinary services and reimbursed for all reasonable
costs, attorney's fees, including allocated costs of in-house counsel, and
expenses occasioned by such default, delay, controversy, or litigation.

            (k) Successor Escrow Agents. Any corporation into which the Escrow
Agent in its individual capacity may be merged or converted or with which it may
be consolidated, or any corporation resulting from any merger, conversion, or
consolidation to which the Escrow Agent in its individual capacity shall be a
party, or any corporation to which substantially all the corporate trust
business of the Escrow Agent in its individual capacity may be transferred,
shall be the Escrow Agent under this Agreement without further act.

            (l) Tax Savings. The Shareholder Representative may at any time
within 6 years after Closing while the Group Companies are ninety percent (90%)
subsidiaries (as defined for the purposes of Section 9 of TCA) of the Purchaser
instruct the auditors of that Group Company to certify in writing (at the
Indemnifying Parties' expense) (i) whether a Tax Liability which has resulted in
payment being made in full by the Indemnifying Parties under Section 6.2 has
given rise to Tax savings for a Group Company that have arisen only as a result
of that matter giving rise to such payment and (ii) the amount of such Tax
savings. Then, upon realization of such Tax savings by the relevant Group
Company, an amount equal to the lesser of (i) the amount of such Tax saving so
certified, and (ii) the amount that can be returned to the Indemnifying Parties
without putting the relevant Group Company in a worse position than if the Tax
savings had not arisen, shall be set off against any payment then or
subsequently due from any of the Indemnifying Parties under this Agreement in
the proportions determined by reference to the relevant "Allocation Percentage"
as set forth on the Schedule of Shareholders.

      6.4 Shareholder Representative.

            (a) Each of the Shareholders hereby appoints the Shareholder
Representative, as its agent and attorney-in-fact, for and on behalf of each of
the Shareholders to give and receive notices and communications, to authorize
payment to any Indemnified Party from the Escrow Fund in satisfaction of claims
by any Indemnified Party, to object to such payments, to agree to, negotiate,
enter into settlements and compromises of, and demand arbitration and comply
with orders of courts and awards of arbitrators with respect to such claims, to
assert, negotiate, enter into settlements and compromises of, and demand
arbitration and comply with orders of courts and awards of arbitrators with
respect to, any other claim by any Indemnified Party against any Shareholder or
by any such Shareholder against any Indemnified Party or any dispute between any
Indemnified Party and any such Shareholder, in each case relating to this
Agreement or the transactions contemplated hereby, and to take all other actions
that are either (i) necessary or appropriate in the judgment of the Shareholder
Representative for the accomplishment of the foregoing or (ii) specifically
mandated by the terms of this Agreement. Such agency may be

                                      -70-


changed by SCG from time to time upon not less than thirty (30) days' prior
written notice to the Purchaser (and each of the Management Shareholders
expressly acknowledges the sole and absolute discretion of SCG to make such
determination). A vacancy in the position of Shareholder Representative may be
filled by SCG. No bond shall be required of the Shareholder Representative, and
the Shareholder Representative shall not receive any compensation for its
services. Notices or communications to or from the Shareholder Representative
shall constitute notice to each of the Shareholders.

            (b) The Shareholder Representative shall not be liable for any act
done or omitted hereunder as Shareholder Representative while acting in good
faith and in the exercise of reasonable judgment. The Shareholders shall each
indemnify the Shareholder Representative and hold the Shareholder Representative
harmless against any loss, Liability, or expense incurred without gross
negligence or bad faith on the part of the Shareholder Representative and
arising out of or in connection with the acceptance or administration of the
Shareholder Representative's duties hereunder, including the reasonable fees and
expenses of any legal counsel retained by the Shareholder Representative
("Shareholder Representative Expenses"). A decision, act, consent, or
instruction of the Shareholder Representative, including but not limited to an
amendment or waiver of this Agreement pursuant to Article VIII hereof, shall
constitute a decision of each of the Shareholders and shall be final, binding
and conclusive upon each of the Shareholders; and the Escrow Agent and the
Purchaser may rely upon any such decision, act, consent or instruction of the
Shareholder Representative as being the decision, act, consent, or instruction
of each of the Shareholders. The Escrow Agent and the Purchaser are hereby
relieved from any liability to any Person for any acts done by them in
accordance with such decision, act, consent or instruction of the Shareholder
Representative.

      6.5 Maximum Payments; Remedy

            (a) Except with respect to the Special Loss Warranties, Covenants,
and Indemnities and as otherwise set forth in this Section 6.5, recourse against
the Escrow Fund shall be the sole and exclusive remedy of the Indemnified
Parties against the Indemnifying Parties with respect to indemnification claims
pursuant to Section 6.2 of this Agreement. The maximum amount an Indemnified
Party may recover individually from any Indemnifying Party pursuant to the
indemnity set forth in Section 6.2 above for Losses recovered from the Escrow
Fund shall be limited to an amount equal to such party's allocated portion of
the Escrow Fund as set forth under the caption "Allocation of Escrow Fund" on
the Schedule of Shareholder.

            (b) Notwithstanding anything to the contrary set forth in this
Agreement, the maximum amount an Indemnified Party may recover individually from
any Indemnifying Party for any breach or inaccuracy of the Special Loss
Warranties, Covenants, and Indemnities shall be limited to an amount equal to
the aggregate consideration received by such Shareholder pursuant to this
Agreement as determined by multiplying, with respect to each Shareholder, the
amount set forth for such Shareholder under the caption "Allocation Percentage"
on the Schedule of Shareholders by the aggregate consideration (including
Earnout Payments, if any, and payment, if any, for any Working Capital Excess)
paid by the Company to all Shareholders (provided that in each case, the
Indemnified Parties shall recover any such Losses first from the Escrow Fund and
then directly from the Indemnifying Parties). Subject to the terms of the Surety
Agreement and in any event where an Indemnified Party would be permitted under
this Agreement to

                                      -71-


recover directly against an Indemnifying Party, the indemnification liability of
SCG with respect to the Special Loss, Warranties, Covenants, and Indemnities
shall be joint and several, and the indemnification liability of the Management
Shareholders shall be several but not joint.

            (c) Notwithstanding anything to the contrary set forth in this
Agreement, nothing in this Agreement shall limit the Liability of any
Shareholder (and the Escrow Fund shall not be the exclusive remedy) in respect
of Losses arising out of any common law fraud or willful and knowing
misrepresentation or willful and knowing breach on the part of any Shareholder.
The parties further acknowledge that the Purchaser shall recover any Losses
resulting from any common law fraud or any willful and knowing misrepresentation
or willful and knowing breach by any Shareholder, either from the Escrow Fund or
directly from such Shareholders, at the Purchaser's sole election.

            (d) All sums payable by the Indemnifying Parties to the Indemnified
Parties pursuant to the indemnity in Section 6.2 above shall be paid free and
clear of all deductions or withholdings save only as may be required by
applicable Legal Requirements. If any such deductions or withholdings are
required by applicable Legal Requirements, the Indemnifying Parties shall be
obliged to pay to the Indemnified Parties such sum as will after such deduction
or withholding has been made leave the Indemnified Parties with the same amount
as it would have been entitled to receive in the absence of any such requirement
to make a deduction or withholding. If any sum payable by the Indemnifying
Parties to the Indemnified Parties pursuant to the indemnity in Section 6.2
above shall otherwise be subject to Taxation in the hands of the recipient the
same obligation to make an increased payment shall apply in relation to such
Taxation as if it were a deduction or withholding required by applicable Legal
Requirements, as referred to above.

THIS SURETY AGREEMENT is made on the 4th day of July, 2005 by:

(1)   ANTHONY J. BOYLE, PETER CROWLEY AND MICHAEL J. MCGINLEY (the "SURETIES",
      and any one a "SURETY")

(2)   JOSEPH MOORE, DAMIAN GUERIN, NIALLO CARROLL (the "SUPPLEMENTAL SURETIES")

IN FAVOUR OF

(3)   PC-TEL, INC. a Delaware corporation having its principal place of business
      at 8725 West Higgins Road, Suite 400, Chicago, Illinois 60631 U.S.A.
      ("PC-TEL")

BACKGROUND

(1)   PC-Tel is proposing to purchase the entire issued share capital of Sigma
      Wireless Technologies Limited (the "COMPANY") pursuant to the terms of a
      Share Acquisition Agreement dated 4th July, 2005 (the "Share Acquisition
      Agreement")

(2)   Under the terms of the Share Acquisition Agreement, each of the
      shareholders of the Company (the "SELLING SHAREHOLDERS") made certain
      representations and warranties to PC-Tel.

(3)   The Sureties are, inter alios, the legal and beneficial owners of shares
      in Sigma Communications Group Limited ("SCG"), one of the Selling
      Shareholders in the Company, and the Supplemental Sureties are the legal
      and beneficial owners of shares in the Company.

(4)   The Supplemental Sureties are parties for whom SCG has at the request of
      PC-TEL agreed to be jointly liable for breach of representations and
      warranties in the terms specified in the Share Acquisition Agreement.

      NOW THIS DEED WITNESSETH as follows:-

1.    SURETY

      1.1   In consideration of the PC-Tel purchasing the entire issued share
            capital of the Company, the Sureties hereby agree to act as sureties
            for SCG in the event that SCG is unable to satisfy a claim made
            against it by PC-TEL, its successors or assigns pursuant to the
            terms of Article VI of the Share Acquisition Agreement for any
            Special Loss Warranties, Covenants and Indemnities (as defined in
            the Share Acquisition Agreement) for fraud or wilful and knowing
            misrepresentation or wilful and knowing breach on the part of the
            Selling Shareholders or SCG PROVIDED THAT (save in the event of
            fraud or wilful and knowing misrepresentation or wilful and knowing
            breach) the Escrow Fund provided for in



            the Share Acquisition Agreement is no longer available to satisfy
            any such claim and subject to the provisions as to maximum payment
            provided in Section 6.5 (b) and (c) of the Share Acquisition
            Agreement.

      1.2   The Sureties hereby unconditionally and irrevocably covenant to pay
            on demand to PC-Tel all and every sum or sums of money due, owing or
            incurred to PC-Tel by SCG, or from SCG jointly with any other person
            or persons together with all interest in the event that:

            (a)   a claim made by PC-Tel against SCG remains unsatisfied for
                  more than 60 days after formal demand; or

            (b)   SCG has been or is in the process of being wound up, within 60
                  days of the demand from PC-Tel,

      1.3   In the event one of the events specified in Clause 1.2(a)or (b)
            occurs and that the Supplemental Sureties or any of them have not
            discharged their several proportion of such claim under the terms of
            the Share Acquisition Agreement, such Supplemental Surety who has
            not so discharged their proportion shall also be liable as if each
            were a Surety in the proportions specified in the Schedule up to the
            maximum amount received by him as consideration pursuant to the
            Share Acquisition Agreement.

2.    INTEREST

      Interest shall accrue on all amounts demanded but unpaid under this Surety
      Agreement (the "DEFAULTED AMOUNT") calculated day by day from the date of
      demand until full payment (as well after as before judgment) with interest
      on such amount equivalent to the average Euribor rate on such amounts for
      the previous 30 days per annum.

3.    PAYMENTS

      All sums payable by the Sureties under this Surety Agreement shall be made
      to the PC-Tel in full in such manner as PC-Tel may direct and in the same
      currency as the relative payments were due to be made by SCG free of any
      present or future taxes levies imposts duties charges fees or withholdings
      and without set-off or counterclaim or any restriction condition or
      deduction whatsoever. If the Sureties are required by law, practice or
      regulation (whether or not such practice or regulation has the force of
      law) to make any deduction or withholding the Sureties will promptly pay
      to PC-Tel such additional amount as would result in the net amount
      received by PC-Tel being equal to the full amount which would have been
      receivable had there been no deduction or withholding and the Sureties
      shall indemnify PC-Tel against any losses or costs incurred by PC-Tel by
      reason of any failure of the Sureties to make such deduction or
      withholding. PC-Tel will co-operate with the Sureties and the Supplemental
      Sureties in relation to any forms or other documents required to minimize
      such withholding.. Any payments made by the Sureties or the Supplemental
      Sureties in satisfaction of the indemnification provisions for Losses (as
      defined in the Share Acquisition Agreement) shall constitute in the case
      of the Sureties a reduction of the consideration payable to SCG
      Shareholders pursuant to



      Section 1.2 of the Share Acquisition Agreement and in the case of the
      Supplemental Sureties shall constitute a reduction of the consideration
      payable to them as Management Shareholders pursuant to Section 1.2 of the
      Share Acquisition Agreement.

4.    GENERAL

      4.1   The liability of the Sureties and the Supplemental Sureties (if
            applicable) hereunder shall be several in the appropriate
            proportions specified in the Schedule hereto and every agreement,
            undertaking, covenant, representation and warranty on the part of
            each Surety shall be construed accordingly and all references to the
            Sureties herein shall where the context requires or admits be
            construed as references to any one or more of them. If the whole or
            any part of this Surety Agreement be now, or hereafter,
            unenforceable against one or more person acting as surety for any
            reason whatsoever or if this Surety Agreement is not executed by any
            person who is to act as Surety this Surety Agreement shall
            nevertheless be and remain fully binding upon and enforceable
            against the other persons acting as surety as if it had been made by
            PC-Tel with only such other persons but to secure the liabilities of
            SCG to PC-Tel.

      4.2   These presents shall bind the Sureties and the Supplemental Sureties
            notwithstanding that they, collectively or individually cease to
            hold a legal or beneficial interest in SCG.

      4.3   These presents shall bind the Sureties' and Supplemental Sureties
            personal representative(s) but shall not be assigned by them.

      4.4   In the event of any dispute arising between the parties to this
            agreement, the Sureties and the Supplemental Sureties hereby
            covenant with each other and with PC-Tel to adhere to and to perform
            and observe the provisions of Article 6.3 of the Share Acquisition
            Agreement to resolve the dispute.

5.    GOVERNING LAW

      This Agreement shall be governed by and construed in accordance with the
      laws of Ireland.

6.    JURISDICTION

      6.1   Each of the parties to this Agreement irrevocably agrees that the
            courts of Ireland are to have non-exclusive jurisdiction to settle
            any dispute arising out of or in connection with this Agreement and,
            for such purposes, irrevocably submits to the non-exclusive
            jurisdiction of such courts. Any proceeding, suit or action arising
            out of or in connection with this Agreement ("the Proceedings") may
            therefore be brought in the courts of Ireland.

      6.2   Each of the parties to this Agreement irrevocably waives any
            objection to Proceedings in the courts referred to in Clause 6.1 on
            the grounds of venue or on the grounds of forum non conveniens.



      6.3   The submission to the non-exclusive jurisdiction of the courts
            referred to in Clause 6.1 shall not (and shall not be construed so
            as to) limit the right of the parties to this Agreement, or any of
            them, to take Proceedings against any of the parties to this
            Agreement, in any other court of competent jurisdiction, nor shall
            the taking of Proceedings in any one or more jurisdictions preclude
            the taking of Proceedings in any other jurisdiction (whether
            concurrently or not) if and to the extent permitted by applicable
            law.

                  Shareholders to the Purchaser at the Closing Date and pay such
                  contributions to the Main Scheme on behalf of each such

                  Scheme on or before the Pension Transfer Date;

            (b)   the Purchaser's Scheme will at the Pension Transfer Date in
                  accordance with and subject to its provisions provide benefits
                  equivalent to those provided under the Main Scheme at that

            (c)   the Purchaser and the trustees or scheme administrator of the
                  Purchaser's Scheme will use all reasonable endeavours to

                  respect of Pensionable Service in the Main Scheme before the
                  Pension Transfer Date which are no less favourable overall
                  than the benefits that would have been provided for or in
                  respect of him under the Main Scheme in respect of Pensionable



                  Service before the Pension Transfer Date if he had remained a
                  member of the Main Scheme up to the date of his retirement
                  death or leaving service;

            (f)   if on the Payment Date the total amount transferred from the
                  Main Scheme to the Purchaser's Scheme is greater than the
                  Transfer Amount (such difference being hereinafter called the
                  "Excess") the Purchaser shall pay to the Shareholders an
                  amount equal to the Excess. The Excess shall be adjusted in
                  the manner prescribed in the Actuary's Letter between the
                  Payment Date and the date of payment of the Excess.

4.    SHAREHOLDERS' OBLIGATIONS

      The Shareholders undertake with the Purchaser that:

      4.1   On the Payment Date the Shareholders shall pay, or shall procure
            that the trustees of the Main Scheme shall pay to the trustees of
            the Purchaser's Scheme the Transfer Amount in cash (or such other
            assets as the trustees or scheme administrator of the Purchaser's
            Scheme and the trustees of the Main Scheme agree); and

      4.2   if on the Payment Date the total amount transferring from the Main
            Scheme to the Purchaser's Scheme is less than the Transfer Amount or
            if no amount is transferred (such deficiency being hereinafter
            called the "Shortfall") the Shareholders shall pay to the Purchaser
            an amount equal to the Shortfall. The Shortfall shall be adjusted in
            the manner prescribed in the Actuary's Letter between the Payment
            Date and the date of actual payment of the Shortfall.

5.    TRANSFER AMOUNT

      5.1   The Shareholders and the Purchaser will on request furnish or
            procure that there will be furnished all necessary information and
            data in their possession to the Shareholders' Actuary and the
            Purchaser's Actuary for the purpose of calculating and verifying the
            Transfer Amount.

      5.2   As soon as reasonably practicable following the Pension Transfer
            Date the Shareholders' Actuary and the Purchaser's Actuary will
            consult with each other with a view to agreeing the Transfer Amount.

      5.3   Any dispute between the Shareholders' Actuary and the Purchaser's
            Actuary concerning the calculation of the Transfer Amount shall in
            the absence of agreement between them be referred to an independent
            actuary (who shall act as an expert and not an arbitrator) agreed by
            the Shareholders and the Purchaser or failing such agreement
            appointed by the President for the time being of the Society of
            Actuaries in Ireland whose decision shall be final and binding upon
            the parties and whose expenses shall be borne equally by the
            Shareholders and the Purchaser.



6.    ADDITIONAL VOLUNTARY CONTRIBUTIONS

      Any voluntary contributions made by the Transferring Employees to the Main
      Scheme (and the investments or moneys representing or deriving from such
      contributions) shall be disregarded for the purposes of calculating the
      Transfer Amount. The Shareholders shall use reasonable endeavours to
      procure that the trustees of the Main Scheme and the AVC Scheme shall as
      soon as reasonably practicable after the Pension Transfer Date pay or
      transfer to the trustees of the Purchaser's Scheme (or procure the payment
      of or transfer of) the assets and/or the amount of any voluntary
      contributions made by the Transferring Employees.
