that, for the purposes of this Agreement, the operations contemplated in
Section 3.1.1 above shall be deemed as a single and sole action and that if
one of the steps fails or is incompletely performed, the Quota Purchase
Closing shall be deemed not to have taken place.

     3.2  PURCHASE PRICE.

price to be paid by Buyer to Seller, and to be received from Buyer by Seller,
in order to acquire the Participation ("Purchase Price") is equal to four
hundred twenty two and one-half billion Italian Lire (ITL 422,500,000,000),
("Purchase Price"), as detailed on Schedule 3.2.1, and shall be divided

reasons other than those already provided for in Section 3.3, 3.4 and 3.5.
herein, then the Purchase Price shall be adjusted upward to reflect that
higher valuation established by such court appointed technical expert.

     3.2.2  PAYMENT AND LIABILITIES. The Purchase Price will be paid by Buyer
to Seller on the Quota Purchase Closing Date, by electronic funds transfer or
by internal bank branch transfer from the Buyer's account, in each case to
the Sellers' bank accounts at Sellers' Bank, in immediately available funds
in Italian Lire. Such transfer will be timely made to enable Sellers' Bank to

Quota Purchase Closing. Upon the terms and subject to the conditions hereof,
as of the Quota Purchase Closing, through sale of the Participation in the
Company, Seller will indirectly transfer to Buyer, and Buyer will indirectly
assume, through its ownership of the Participation, and thereafter shall
cause the Company to fully perform and discharge, on a timely basis and in
accordance with their respective terms, the liabilities and obligations of
the Company, agreed to be assumed pursuant to this Agreement.

Purchase Closing, Seller will prepare and deliver to Buyer a closing
inventory/asset statement for the transaction, as of the Quota Purchase
Closing Date ("Closing Inventory/Asset Statement"). The purpose of the
Closing Inventory/Asset Statement is to show the numerical increase or
decrease, as applicable, in the physical fixed assets and inventory of the
Manufacturing Operations/Company (other than land and buildings and real
estate fixtures), between the amount set forth on Schedule 3.3 to this
Agreement at the signing of this Agreement, and the amount existing as of the
Quota Purchase Closing Date. Each item of inventory will be assigned the same
standard cost and manufacturing value add that is set forth for such items of
inventory at the date this Agreement is signed. Each physical fixed asset
(other than inventory and land and buildings and real estate fixtures) will
be assigned its net book value

                                                                             7
<PAGE>

on the books of Seller as of the Quota Purchase Closing Date. The Closing
Inventory/Asset Statement shall became final and binding upon the Parties
unless Buyer gives written notice of its disagreement of such items included
on or excluded from the Closing Inventory/Asset Statement within twenty (20)
days following Seller's receipt of the Closing Inventory/Asset Statement,
which disagreement will be based solely upon the methodology set forth in
Schedule 3.3 for reviewing the Closing Inventory/Asset Statement. Any such
notice shall specify in reasonable detail the nature of any disagreement so
asserted. In the event that the Closing Inventory/Asset Statement (as finally
resolved) indicates an adjustment in the Purchase Price, within fifteen (15)
days of such statement becoming final, such adjustment shall be made by
either (i) Seller transferring by immediately available electronic funds
transfer to Buyer in the event that Buyer overpaid at the Quota Purchase
Closing or (ii) Buyer transferring by immediately available electronic funds
transfer to Seller in the event that Buyer underpaid at the Quota Purchase
Closing.

     3.4.  ADDITIONAL PURCHASE PRICE ADJUSTMENT. The Purchase Price will also
be adjusted upwards after the Quota Purchase Closing Date to include amounts
equal to the aggregate of all of the following gross asset items that are
transferred to Buyer as part of the Company or otherwise, all in Italian
Lire: cash and near cash equivalents; prepaid expenses; and accounts
receiveable, including the receivables with Employees as set forth in
Schedule 3.5., Section 4, in each case related to the Manufacturing
Operations. In the event that such amounts are transferred to the Buyer as
part of the Company, Buyer shall pay the aggregate amounts so transferred by
immediately available electronic funds transfer to Seller within fifteen (15)
days of the Quota Purchase Closing Date.

     3.5  PAYABLES PURCHASE PRICE ADJUSTMENT. The Parties agree that the
Purchase Price will also be adjusted downwards after the Quota Purchase
Closing Date to include amounts equal to the aggregate of (i) the total
liabilities of the Company to its Employees as set forth in Schedule 3.5.,
Sections 1, 2, 3, (ii) accounts payable transferred with the Company, which
remain unpaid by the Company and the Seller and its Affiliates, due for the
purchase of the assets by the Company or the Seller and its Affiliates of
inventory and physical fixed assets of the Manufacturing Operations/Company
whose value has already been received by the Seller through the asset
valuation and payment mechanism set forth in Section 3.2.1 or Section 3.3,
and (iii) the Seller's relative pro rata share, based upon calendar days
prior to the Quota Purchase Closing Date over the billing period, of unpaid
accounts payable transferred with the Company, under contracts for services
or for services, such as utility services, provided prior to the Quota
Purchase Closing Date, where either (x) billing cycles for such services
accounts payable cover the period both before and after the Quota Purchase
Closing Date or (y) such services or payables relate exclusively to periods
prior to the Quota Purchase Closing Date; all except as otherwise expressly
provided under this Agreement for assumed liabilities. In the event that such
accounts payables are transferred to the Buyer as part of the Company, Seller
shall pay the aggregate amounts, as set forth in (i), (ii) and (iii) of this
Section 3.5, so transferred to Buyer, by immediately available electronic
funds transfer to Buyer within fifteen (15) days of the Quota Purchase
Closing Date. To the extent that Seller or its Affiliates

          MANAGEMENT OF THE COMPANY PRIOR TO THE QUOTA PURCHASE CLOSING

     Seller, for the period between the Date of Execution and the Quota
Purchase Closing, will manage the Manufacturing Operations in the ordinary
course of business, except as the preparation for this transaction varies from
such ordinary course.

     Seller further agrees that between the Date of Execution of this
Agreement and the Quota Purchase Closing, it will not, without the Buyer's
prior written consent: effect a merger of the Company with other companies, or
demerge (spin-off) assets used in the Manufacturing Operations or take any
action or cause the Manufacturing Operations or the Company to take any
action, other than as contemplated by the Operative Agreements and other than
in the ordinary course of business, that would have a material adverse effect
upon the Manufacturing Operations or Company.


                                  ARTICLE 5
  OBLIGATIONS OF THE PARTIES PRIOR TO OR AFTER THE QUOTA PURCHASE CLOSING

     5.1 RESIGNATIONS. Prior to the completion of the Quota Purchase Closing
Seller shall arrange that all the members of the board of directors and all
the members of the board of statutory auditors of the Company shall have
tendered their resignations in writing, effective as of the Quota Purchase
Closing, from all the offices held by them in the Company. Seller will
cooperate with Buyer so that the Company can adopt, as soon as practical
after the Quota Purchase Closing, actions necessary to appoint a new board of
directors and statutory auditors chosen by Buyer.

     5.2 RESOLUTION. Buyer and its Affiliates hereby irrevocably undertake
not to take, participate in, or cause to be taken by the Company or
others, any action for liability or damages against any of the officers,
employees, directors or statutory auditors of the Company appointed by the
Seller and resigning from their offices in compliance with Section 5.1,
arising out of or in connection with the activities of such representatives
acting in such capacities prior to the Quota Purchase Closing. Buyer agrees
that, concurrent with the Quota Purchase Closing, a quotaholders resolution
will be validly adopted in a form satisfactory to Seller, confirming this
Section 5.2.

     5.3. EMPLOYMENT MATTERS. The term Employee(s) shall mean the employee(s)
being employed with the Company at the time of the Quota Purchase Closing.
The employees employed by Seller in connection with the Manufacturing
Operations at the date hereof are listed in Schedule 5.3.1. Schedule 5.3.1
also shows their present status of employment. This Schedule will be updated
immediately prior to the Quota Purchase Closing to reflect changes


                                                                           9

<PAGE>

related to such employee(s) between the Date of Execution and the Quota
Purchase Closing. Seller will not intentionally enlarge the total number of
Employees above the number shown on Schedule 5.3.1 without the prior written
consent of Buyer. The number of Employees may vary due to events outside of
Seller's control, transactions in the ordinary course of business,
preparations for the transaction contemplated by the Operative Agreements, or
the effects of the applicable transfer of undertaking legal provisions.

Seller and Seller's Affiliates have in relation to each of such employees,
complied with all the terms of the respective employment statutes,
regulations, codes of conduct, collective agreements and orders relevant to
the listed status of the Employees.

Buyer agrees to apply to the Employees, for a period of three (3) years after
the Quota Purchase Closing Date, the terms and conditions of employment
provided by the Seller to such Employees immediately prior to the Quota
Purchase Closing Date except for changes which might be agreed through
individual or collective agreements. Such terms and conditions of employment
are summarized in Schedule 5.3.2. Further, Buyer agrees to cause the Company
to comply with article 2112 of the Italian Civil Code. Previously accrued
employment benefits and future employment benefits, which cannot be provided
or cannot be provided in precisely the same form or manner by Buyer because
of the change of ownership in the Company from Seller to Buyer (e.g.
incentive stock options), shall be financially compensated by Buyer on an
equivalent level.

Buyer agrees that, in relation to Seller and Seller's Affiliates, the Company
is solely liable for any claims of its Employees which relate to the period
after the Quota Purchase Closing Date, including but not limited to areas
where the applicable law provides for any joint liability of Seller and the
Company or Buyer as a consequence of the transfer of the Manufacturing
Operations from Seller into the Company and the transfer of the Company from
Seller to Buyer and that Seller is solely liable for any claims of Employees
which relate to the period up to and including the Quota Purchase Closing
Date, including, but not limited to, arrears where the applicable law
provides for joint liability of the Seller and the Company as a consequence
of the transfer of the Manufacturing Operations from Seller into the Company,
provided such claims are not pre-closing liabilities expressly transferred
with the Company pursuant to this Agreement.

Buyer and Seller agree to furnish each other with such information concerning
Employees as is reasonably requested, subject to the privacy policies of both
Parties and subject to the extent permissible under applicable law.


     5.4 IBM COMMERCIAL SOFTWARE. The Buyer agrees that it will execute a
standard IBM commercial software licensing agreement, in the forms attached
hereto as Exhibit S, effective on the Quota Purchase Closing Date, to cover
all of the commercially offered IBM software that is utilized by the Company,
if any, where that software is not being provided as part of a service to the
Company by IBM under the Transition Services Agreement. The


                                                                           10

referenced software agreement will provide the standard IBM offerings and
prices for the licensing, maintenance and support of such IBM commercially
available software.

     5.5. COMPANY TAXES. Except as provided in Section 9.2, at the Quota
Purchase Closing Date the Company will have complied with its duties under
any tax and social security laws and regulations in force from time to time
and applicable to the Company itself or the Manufacturing Operations and
taxes, interest, and penalties, if any, arising from the failure to comply
with such duties will be borne by Seller. With reference: (a) to the
provisions under article 26 of D.P.R. 26/10/1972 No. 643, Seller covenants
that there will be no tax liability against or to be borne by the Company
with reference to the transfer to the Company of the land and buildings of
the Manufacturing Operations; and (b) to the provisions under article 14 of
D. Lgs. 18/12/1997 No. 472, and subject to Section 9.2, Seller covenants that

Italian Civil Code shall not apply in connection with the sale of the
Participation under this Agreement.

Schedule 9.1, if the transfer of the Participation under this Agreement
results in the applicable governmental agency with such authority exercising
any right it might have to (i) require early repayment of such loans, with
below market rates prior to the maturity date thereof or (ii) require
repayment of outright grants made under those contracts, the following
adjustment will be made: an amount equal to the outright grants so repaid and
the loan premium (the remaining term, amount and payment stream under such

contract, agreement or other arrangement, executed by IBM Italia S.p.A. or by
IBM Semea Servizi Finanziari S.p.A.; (iv) any judgment, injunction, decree,

organized, validly existing and in good standing, under the laws of Italy and
is duly qualified, under all applicable laws, to carry out the Manufacturing
Operations, subject to Section 6.2.4, except where the failure to so qualify
would not, either individually or combined with other breaches of
representations and warranties by Seller and its Affiliates under the
Operative Agreements, have a material adverse effect upon the transactions
contemplated by the Operative Agreements.

          6.2.2 FINANCIAL INFORMATION. The Financial Information provided by
Seller to Buyer with respect to the Transferred Assets was derived from or
included in the financial records of the Seller, which have been maintained

at the Quota Purchase Closing Date will have been, immediately prior to the
Closing, operated or used in compliance with applicable laws or regulations,
except where the failure to be in compliance would not, either individually

and its Affiliates under the Operative Agreements, have a material adverse
effect.

          6.2.4 GOVERNMENTAL AUTHORIZATIONS -- COMPLIANCE WITH LAW. The
Company, prior to Closing, will have duly obtained, or will have filed an
application to obtain, all required authorizations, concessions and permits
whether issued by governmental, regional, or local authorities required for

other breaches of representations and warranties by Seller and its Affiliates
under the Operative Agreements, have a material adverse effect. All permits
held at the date hereof by Seller in respect of the Manufacturing Operations,
which are transferable and exclusively utilized for such operations will,
prior to Closing, be transferred or will have been applied for a transfer, to
the Company.

                                                                           13

<PAGE>

          6.2.5  LITIGATION.  There is no suit, action, arbitration,
proceeding or governmental proceeding or prosecution pending or, to Seller's
knowledge, threatened in a writing to IBM Italia or its Affiliates by or
against the Company or Seller in respect of the Manufacturing Operations and
there is no outstanding default of a judgment, decree, injunction, rule or
order of any Court, Board of Arbitrators or governmental or tax authority
against the Company or the Seller; in each case which, either individually or
combined with other breaches of representations and warranties by Seller and
its Affiliates under the Operative Agreements, have a material adverse effect.

          6.2.6  NO OTHER REPRESENTATIONS & WARRANTIES. Except for the
express representations and warranties made by Seller in this Article 6,
Seller makes no representation or warranty, express or implied, concerning
either Seller, the Company or the Manufacturing Operations, it being
specifically understood by Buyer that, except for the express warranties set
forth in this Article 6, the Company's business is being transferred "as is"
in all respects. Seller specifically disclaims any warranty of suitability or
fitness for any particular purpose of Buyer's, whether or not Seller has been
made aware of any such purpose.

          6.3.  REGARDING THE MANUFACTURING OPERATIONS. Annexed as Schedule
6.3 subschedules hereto is a listing of the assets and liabilities of the
Manufacturing Operations, all of which (subject to acquisitions and
dispositions in the ordinary course of business between the date hereof and
the Quota Purchase Closing Date) will be assets and liabilities of the
Company as of the Closing:

     (a)     a description of the land and buildings, described in Schedule
6.3(a);

     (b)     a listing of the machinery, production equipment, computer
equipment, hardware, fixtures, vehicles, furnishings, parts, supplies,
accessories, tools, dies, jigs and other fixed assets described in Schedule
6.3(b);

     (c)     an estimated inventory valuation, in Schedule 6.3(c);

     (d)     a listing of the contracts described in Schedule 6.3(d)

          6.4  RECORDS. At or prior to Closing, copies of the operational
records relating to the Manufacturing Operations and the assets described in
Schedule 6.3, including, without limitation, the Employees' records, cost
records, manufacturing data, outstanding purchase orders, production records,
supply records, inventory records, correspondence files and environmental
reports, data, information and materials (together with, in the case of such
information which is stored electronically, copies of the media on which the
same is stored), all in conformance with applicable law, will be provided.

          6.5.  SUPPLIERS. There are a number of suppliers to the
Manufacturing Operations whose products and services are not covered by
contracts that are directly with the Company.


                                                                            14

<PAGE>

These suppliers are part of larger contracts for the provision of products
and services to other entities owned by the Seller, in addition to the
Manufacturing Operations. Between the Date of Execution and the Closing, the
Company and the Seller will initiate contract negotiations with such
suppliers, for the provision of such products and services under separate
contracts with the Company. A list of the current products and services which
have been identified as falling within this category as of the Date of
Execution is set forth in Schedule 6.5.

          6.6  SOFTWARE. The third party software licenses listed on Schedule
6.3(d) are the licenses being transferred along with the Company. There are
other third party software packages being utilized in the Manufacturing
Operations whose licenses are not being transferred, either because the
licenses are not transferable, or because other units of the Seller utilize
such software and need to retain the licenses; therefore the Buyer will need
to separately obtain licenses for such third party software; the currently
identified third party software that falls into this category is listed in
Schedule 6.6.

                   REPRESENTATIONS AND WARRANTIES OF BUYER


     7.1 Celestica Inc. and Celestica Europe Inc. hereby represent and
warrant to Seller as of the date hereof and as of the Quota Purchase Closing
Date, each individually for such buying entity:

          7.1.1 ORGANIZATION AND GOOD STANDING. Celestica Inc. is duly
organized, validly existing and in good standing, under the laws of the
Province of Ontario, Canada and is duly qualified, under all applicable laws,
to enter into this Agreement and to perform any and all of its obligations
under this Agreement. Celestica Europe Inc. is duly organized, validly
existing and in good standing, under the laws of the Province of Ontario,
Canada and is duly qualified, under all applicable laws, to enter into this
Agreement and to perform any and all of its obligations under this Agreement.
This Agreement has been duly executed and delivered by Buyer and this
Agreement constitutes a legal, valid and binding obligation of Buyer
enforceable against Buyer in accordance with its terms.

          7.1.2 NO BANKRUPTCY PROCEEDINGS. Each Buyer is validly existing
and no liquidator, administrative receiver, administrator or similar officer
has been appointed in respect of it and no action is currently being taken
with a view to appoint any such liquidator, receiver, administrative
receiver, administrator or similar officer. There is no action or proceeding
now pending or threatened in writing to dissolve Buyer or to declare its
corporate

                                                                           17

rights and powers, or any of them, to be null and void or to declare that it
or its board of Directors or any of its Directors, officers, agents or
employees has or have exceeded or violated any of its corporate rights or
powers.

          7.1.3 NO BREACH. The execution of this Agreement and of the
transactions contemplated herein will not result in the breach or violation
of any provision of Law as well as of any corporate document of each Buyer
which may affect the validity and enforceability of this Agreement.

          7A.1.4 ENVIRONMENTAL MATTERS. (a) Buyer and Seller agree that the
Environmental Baseline shall be produced and be binding on both the Buyer and
the Seller and shall represent the environmental condition of the Real
Property as of the Quota Purchase Closing Date. The Buyer and Seller shall
select a qualified environmental consultant (the "Consultant") who shall be
mutually agreeable to them, acting reasonably, to conduct over a three month
period an environmental investigation, including testing and sampling of
existing and new boreholes and wells as it considers prudent, of the Real
Property (the "Investigation"), commencing as soon as reasonably possible
after the execution of this Agreement, for the purpose of producing the
Report referred to below outlining the environmental condition of the Real
Property. The consultant shall produce a report (the "Report") of its
findings setting out the location and concentration measurement or level of
each chemical constituent identified on or under the Real Property. The
concentration measurement or level at (and around any location as reasonably
determined by the Consultant) shall be the average of the levels in the
annual site monitoring records of the Seller for the location for the three
years 1997, 1998 and 1999 as well as the new testing, provided that where the
new testing provides a materially different result from previous site
monitoring records, sufficient new testing shall be conducted to provide a
result considered as reliable by the Consultant and the previous site
monitoring records for such location shall be taken into account to the
extent considered appropriate by the Consultant. In arriving at an average
concentration measurement or level the consultant shall be guided by the
norms and procedures generally used and applied by professionals in the
environmental sampling and testing industry. Seller and Seller's affiliates
will co-operate reasonably in connection with the conduct of the
Investigation, including, without limitation, making personnel reasonably
available. The parties further agree that the cost of the Consultant
including the cost to perform additional testing by the Consultant as well as
the creation of the Report shall be borne equally by the parties on a 50%-50%
basis, but in no event will the cost of the Consultant services exceed one
hundred eighty million Lire (ITL 180,000,000). Both parties shall be entitled
to copies of any and all documents created or used by the Consultant in the
performance of its work. If the Environmental Baseline indicates the presence
of Hazardous Material, Seller will undertake any action with respect thereto
which requires a remedial action under Environmental Law which is enforced by
an applicable Governmental Authority.

(b) Buyer agrees that any contamination caused by its consultants or
contractors or itself arising out of or resulting from any due diligence
investigations conducted by the Buyer or its consultants prior to the Quota
Purchase Closing Date shall be the responsibility of the Buyer.


                                                                           18

(c) Without limiting Buyer's ability to rely on Section 6.7, Buyer
acknowledges that is has made its own investigation of the Real Property and
Buyer is aware of the various licenses and permits that the appropriate
Governmental Authorities will require on or after the Quota Purchase Closing
Date, and Buyer agrees and represents that it is responsible for obtaining
any such license or permit that may be required by any Governmental Authority
in order for Buyer to conduct its business operations on the Real Property on
or after the Quote Purchase Closing Date, subject only to Seller's obligation
(which is hereby agreed to) to assist Buyer in the transfer of any
transferable permits or licenses as may be allowed or permitted by applicable
law. Buyer further agrees that it will exercise reasonable efforts to satisfy
and effectuate on or prior to the Quota Purchase Closing Date, or as soon
thereafter as is practicable, the transfer or issuance of all licenses,
permits and other authorizations that are required by any appropriate
Governmental Authority to enable Buyer to operate its business on the Real
Property on or after the Quota Purchase Closing Date.

Purchase Agreement dated February 9, 2000 between IBM Italia S.p.A., IBM
Semea Servizi Finanziari S.p.A., Celestica Inc., and Celestica Europe Inc.,
as amended by the First Amendment dated February 28, 2000 between the parties
("Quota (Share) Purchase Agreement").

This Second Amendment is dated as of May 31, 2000.

WHEREAS

The Parties have agreed that Buyer will buy substantially all of the
inventory owned by the Seller and, in consideration thereof, the Parties
hereby agree to amend the Purchase Price indicated in Section 3.2.1. and the
corresponding Schedule 3.2.1. "Assets Conveyed" of the Quota (Share) Purchase
Agreement. Furthermore the Parties hereby agree to amend Schedule 3.3.
"Methodology for Review of Closing Statement" of the Quota (Share) Purchase

The Parties to the Quota (Share) Purchase Agreement hereby agree to the
following modifications to that agreement:

"3.2.1 PURCHASE PRICE. The Parties agree that the aggregate purchase price to
be paid by Buyer to Seller, and to be received from Buyer by Seller, in order
to acquire the Participation ("Purchase Price") is equal to four hundred
forty one billion three hundred eight million Italian Lire (ITL
441,308,000,000), ("Purchase Price"), as detailed on Schedule 3.2.1, and
shall be divided between IBM Italia S.p.A. and IBM Semea Servizi Finanziari
S.p.A in proportion of their respective quota of capital in the Company,
provided, however, that if the expert valuation performed by the technical
expert appointed by the judge according to article 2343 paragraph 1 of the
Italian Civil Code results in a higher valuation of the Manufacturing
Operations, for reasons other than those already provided for in Section 3.3,
3.4 and 3.5. herein, then the Purchase Price shall be adjusted upward to
reflect that higher valuation established by such court appointed technical
expert."

In addition, the Parties hereby agree that the prior Schedules 3.2.1 and 3.3
of the Quota (Share) Purchase Agreement are hereby replaced with the Schedule
3.2.1 and Schedule 3.3

which are attached to this Amendment and are hereby incorporated as part of
this amendment.

Except as specifically provided for in this Second Amendment, the Quota
(Share) Purchase Agreement shall continue in full force and effect and each
of the parties hereby confirms the terms of the Quota (Share) Purchase

Schedule 3.2.1.   Version 0511


<PAGE>


                  METHODOLOGY FOR REVIEW OF CLOSING STATEMENT


Assets and Inventory at signing are as set forth on Schedule 3.2.1, herein
incorporated by reference.

The following will be the methodology for reviewing the Closing Statement:

1.  The ledger balance of WCE Italia S.r.l. as of the Closing Date will be
    the basis for the Closing Statement.

2.  A physical inventory sample to determine proper quantities will be
    initiated by Seller and Buyer on the Closing Date. Seller will perform a
    Rotating Inventory Audit (RIA) on the Warehouse based on PI (Perpetual
    Inventory) Test check methodology. Additional sampling will be performed
    on Work-in-Process based on MFI system data (Wip on Vimercate/S. Palomba
    manufacturing floor) and PIV system data (Wip consigned to our Vendors).

3.  Inventory will be valued according to Weighted Average Cost (WAC)
    methodology.

4.  Cost of acquisition will be added to the inventory, at 2.5%.

5.  Inventory determined as above will be decreased by a provision for scrap
    of three hundred ten million Lire (310,000,000)

6.  Any completed assembly inventory will be valued at price for cards and at
    BOM plus 9% for box/fab/mes.

7.  A value for labor and overhead effort will be added to the
    work-in-process inventory value, based on the 50% completion methodology
    applicable to either ECAT (i.e. assumes 50% of all production
    steps/profit has been completed in addition to BOM), and Box/Fab/MES
    (i.e. assumes 50% of the 9% markup above BOM, equal to 4.5% of BOM markup
    to be added in addition to BOM).

8.  The cost of all parts sourced from Seller's Microelectronics Division
    (currently valued at 90%) will be multiplied by a factor of 1.11 for the
    purpose of valuing inventory.

9.  All Machinery and Equipment, Furniture and Fixtures, and Data Processing
    Machines will be valued at WCE Italia S.r.l.'s book value.
