of Company as of the Closing Date (adjusted to reverse the effect of purchase
accounting rules that require the value of assets to be written up to their fair
market value on the Bunkatsu Day on the determination of the book value of the
Transferred Assets and to include the full amount of the Unfunded Pension
Liabilities determined in accordance with Schedule 4.4(b)) (the "Estimated
Closing Date Net Assets"). The Estimated Closing Date Balance Sheet shall
reflect any dividends or other distributions declared on or prior to the Closing
Date and payable on or after the Closing Date to Seller. The Initial Purchase
Price payable on the Closing Date shall be adjusted yen for yen as follows: (i)

Pension Liabilities, the Initial Purchase Price shall be decreased by
the amount of such deficit.

     (b) POST CLOSING INITIAL PURCHASE PRICE ADJUSTMENT. The Initial Purchase
Price shall be subject to adjustment after the Closing Date according to this
Section 1.4(b).

          (i) As soon as practicable, but in no event later than forty-five (45)
days after the Closing Date, Buyer shall prepare and shall deliver to Seller an
audited balance sheet of the Company as of the Closing Date (the "Final Closing
Date Balance Sheet"), including a calculation of the net assets of Company as of
the Closing Date adjusted to reverse the effect of purchase accounting rules
that require the value of assets to be written up to their fair market value on
the Bunkatsu Day on such calculation and to include the full amount of the
Unfunded Pension Liabilities determined in accordance with Schedule 4.4(b) (the
"Closing Date Net Assets"), together with a report thereon from an
internationally recognized firm of independent certified public accountants
reasonably satisfactory to Seller stating that the Final Closing Date Balance
Sheet fairly presents the value of the net assets of Company as of the Closing
Date prepared in accordance with GAAP applied consistently with the preparation
of the Estimated Closing Date Balance Sheet. In the event that Buyer fails to
timely deliver the Final Closing Date Balance Sheet for any reason whatsoever,
the Estimated Closing Date Balance Sheet shall be deemed to be and shall be
final, binding and conclusive on Buyer and Seller and the Initial Purchase Price
shall no longer be subject to adjustment.

          (ii) Seller shall have a period commencing upon delivery of the Final
Closing Date Balance Sheet to Buyer and expiring thirty (30) business days after
such delivery date to review the Final Closing Date Balance Sheet. Seller and
Seller's independent certified public accountants ("Seller's Accountants") shall
have full access during regular business hours and upon reasonable notice to all
relevant books and records and employees of Company to the extent necessary to
complete their review of the Final Closing Date Balance Sheet. In the event
Seller disputes that the Closing Date Net Assets was determined in accordance
with GAAP consistently applied with the Estimated Closing Date Balance Sheet,
Seller shall, within thirty (30) business days after delivery of the Final
Closing Date Balance Sheet, deliver a notice to Buyer (the "Adjustment Dispute
Notice"), setting forth in reasonable detail the component or components which
are in dispute and the basis of such dispute. If the parties fail to resolve any
such dispute within thirty (30) business days after receipt by Buyer of the
Adjustment Dispute Notice, the parties shall submit the dispute to Deloitte
Touche Tohmatsu (the "Reviewing Accountant") to review the Closing Date Net
Assets set forth on the Final Closing Date Balance Sheet. Each party hereby
represents and warrants that neither party nor any of its Affiliates uses the
Reviewing Accountant as its accountant or has any material relationship
therewith. The parties shall make available to the Reviewing Accountant all work
papers and all other information and material in their possession relating to
the matters in the Adjustment Dispute Notice. The Reviewing Accountant's
authority shall be limited to determining whether the component or components of
Closing Date Net Assets set forth on the Final Closing Date Balance Sheet which
have been so disputed by the Seller were calculated in accordance with GAAP
consistently applied with the Estimated Closing Date Balance Sheet and, if
necessary, determining the adjustments required to such Closing Date Net Assets
to cause it to be calculated in accordance with GAAP consistently applied with
the Estimated Closing Date Balance Sheet. The Reviewing Accountant shall be
instructed by the parties to use its best efforts to deliver to
<PAGE>

                                      -6-

the parties its determination as promptly as practicable after such submission
of the dispute to the Reviewing Accountant. The parties hereby expressly
agree that the determination of the Reviewing Accountant shall be considered
to be an award made in an arbitration proceeding and shall be final and binding
on the parties (absent fraud or manifest bad faith by the Reviewing
Accountant). The Closing Date Net Assets on the Final Closing Date Balance Sheet
as determined by Buyer (if not disputed), or as modified (if at all) by
agreement of Buyer and Seller or by decision of the Reviewing Accountant, shall
be the "Final Closing Date Net Assets". Each party shall bear its own expenses
and the fees and expenses of its own representatives and experts, including its
independent accountants, in connection with the preparation, review, dispute (if
any) and final determination of the Final Closing Date Net Assets. The parties
shall share equally in the costs, expenses and fees of the Reviewing Accountant.

          (iii) Within five (5) days following determination of the Final
Closing Date Net Assets, the Initial Purchase Price shall be adjusted yen for
yen and payment shall become due as follows: (i) if the Final Closing Date Net
Assets exceeds the Estimated Closing Date Net Assets, the Initial Purchase Price
shall be increased by the amount of such excess and Buyer shall pay over such
excess to Seller in accordance with Section 1.4(b)(iv) below, or (ii) if the
Final Closing Date Net Assets is less than the Estimated Closing Date Net
Assets, the Initial Purchase Price shall be decreased by the amount of such
deficit and Seller shall pay over such deficit to Buyer in accordance with
Section 1.4(b)(iv) below.

          (iv) The payment of any adjustment provided for in this Section 1.4(b)
shall be made by wire transfer of immediately available funds. Any such payment
shall also include interest on the amount of such payment, calculated at the
short term prime rate then offered by most Japanese city banks (toshi ginko) as
according to the most recent financial and economic statistics (kinyu keizai
toukei) reported by the Bank of Japan.

     1.5      REPAYMENT OF INTERCOMPANY LOAN.

          At the Closing, Buyer will, concurrently with paying the Initial
Purchase Price, cause the Company to repay in full all amounts due under the
Intercompany Loan, including all accrued interest thereon.

Employment Conditions"). Buyer shall reasonably cooperate with

or similar labour agreement or arrangement, if any, applicable to any
Transferred Employees. Buyer shall continue the seniority (based on years of
service) of each of the Transferred Employees (as if such employees had been
employed by Company since their individual dates of hire by Seller or its
Affiliates) whose employment is continued by Company and while they remain
employed by Company for the purposes of retirement benefit, pension, vacation,
sick leave and other time off policies. Notwithstanding anything to the contrary
herein, subject however to Section 4.4(c) below, Buyer shall not be obligated to
continue to employ any Transferred Employee after the Closing Date.

Company or of Seller or its Affiliates (including any beneficiary or dependent
thereof), if any, who is not a Transferred Employee and (ii) EPF. Seller shall

the Closing Date for inspection and copying by Seller or its agents at Seller's
expense, upon reasonable request and upon reasonable notice, for a period of
three years after the Closing Date (or such longer period as may be required by
the Purchase and Supply Agreement). No such books, records or documents shall be
destroyed by Buyer or Company without first advising Seller in writing and
giving Seller a reasonable opportunity to obtain possession thereof.

     4.6      COOPERATION IN AUDITS.

prior to the Closing, to the extent permitted by applicable law, Seller, Buyer
and Parent shall take all reasonable action necessary in order to provide Buyer
and Company with the benefits of such consents, transfers, approvals, orders,
qualifications and waivers, and so long as Buyer and Company are provided such
benefits in all material respects, the conditions of Section 5.2(c) and 5.3(b)
shall be deemed satisfied.

     4.8      TAXES.

     Except as otherwise provided herein, Buyer shall be responsible for all

Remediation. In connection with such Anticipatory Remediation work, Seller shall
have the right to access the Properties after the Closing in accordance with

claims against Seller under this Section 4.9.

     4.10     CHANGES IN PRO FORMA PROJECTED FINANCIAL STATEMENTS.

     7.3      SURVIVAL OF REPRESENTATIONS AND WARRANTIES AND ENVIRONMENTAL
              INDEMNITY; KNOWLEDGE OF BREACH.

     (a) Notwithstanding any otherwise applicable statute of limitations, the
representations and warranties included in Articles 2 and 3 shall survive the
Closing for a period of **** after the Closing Date except that (i) the
representations and warranties contained in Sections **** shall survive the
Closing and shall remain in full force and effect ****, (ii) the
representations and warranties contained in Section **** shall survive until
**** set forth in the applicable **** or until the **** within the period of
the relevant **** and (iii) the representations and warranties contained in
Sections **** and *** shall survive until the **** of the Closing Date. In
addition, the indemnity contained in Sections **** shall survive the Closing
only until the **** of the Closing Date. If a claim or notice is given under
Article 7 with respect to any representation or warranty or with respect to
the indemnity in Section **** prior to the applicable expiration date, such
representation or warranty and/or indemnity shall continue ****.

     (b) No party hereto shall be deemed to have breached any representation,
warranty, or covenant if (i) such party shall have expressly notified the other
party hereto in writing, of the particulars of the breach of, or, such
representation, warranty or covenant, or such breach is expressly referred to in
any Schedules hereto and (ii) such other party has permitted the Closing to

such breach or inaccuracy; provided, however, that a disclosure pursuant to this
Section 7.3(b) shall not prejudice the rights of the parties pursuant to Article
6 hereof not to consummate the transactions contemplated by this Agreement.

     7.4      PROCEDURES

     For purposes of this Section 7.4, any party with an indemnification
obligation under this Article 7 or Section 4.9 shall be referred to herein as an
"Indemnifying Party" and any party entitled to indemnification under this
Article 7 shall be referred to as an "Indemnified Party". All claims for
indemnification by any Indemnified Party hereunder shall be asserted and
resolved as set forth in this Section 7.4. In the event that any written claim
or demand for which an Indemnifying Party would be liable to any Indemnified
Party hereunder is asserted against or sought to be collected from any
Indemnified Party by a third party, such Indemnified Party shall promptly, but
in no event more than 15 days following such Indemnified Party's receipt of such
claim or demand, notify the Indemnifying Party of such claim or demand and the
amount or the estimated amount thereof to the extent then feasible (which
estimate shall not be conclusive of the final amount of such claim and demand)
(the "Claim Notice"). The Indemnifying Party shall have 30 days from the
personal delivery or receipt of the Claim Notice (the "Notice Period") to
<PAGE>

                                      -31-

notify the Indemnified Party (a) whether or not the Indemnifying Party
disputes the liability of the Indemnifying Party to the Indemnified Party
hereunder with respect to such claim or demand and (b) whether or not it desires
to defend the Indemnified Party against such claim or demand. All costs and
expenses incurred by the Indemnifying Party in defending such claim or demand
shall be a liability of, and shall be paid by, the Indemnifying Party, subject
to the limitations set forth in Section 7.6 hereof. In the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that
it desires to defend the Indemnified Party against such claim or demand and
except as hereinafter provided, the Indemnifying Party shall have the right to
defend the Indemnified Party (i) by appropriate proceedings and (ii) use or
retain counsel in connection with such defense that is reasonably acceptable to
the Indemnified Party. The Indemnified Party shall make available to the
Indemnifying Party all information reasonably available to such Indemnified
Party relating to such claim or demand. In addition, the Indemnified Party and
the Indemnifying Party shall render to each other such assistance as may
reasonably be requested in order to ensure the proper and adequate defense of
any such claim or demand, or to prosecute claims against third parties for
contribution or on other theories of recovery related to such claim or demand.
The party in charge of the defense shall keep the other party fully apprised at
all times as to the status of the defense or any settlement negotiations with
respect thereto. If any Indemnified Party desires to participate in, but not
control, any such defense or settlement it may do so at its sole cost and
expense. In the event that the Indemnifying Party does not elect to defend the
claim, the Indemnified Party shall not settle a claim or demand without the
consent of the Indemnifying Party (which consent will not be unreasonably
withheld). The Indemnifying Party shall not, without the prior written consent
of the Indemnified Party, settle, compromise or offer to settle or compromise
any such claim or demand (i) on a basis which would result in the imposition of
a consent order, injunction or decree which would restrict the future activity
or conduct of the Indemnified Party or any subsidiary or Affiliate thereof
without the written consent of the Indemnified Party (which consent will not be
unreasonably withheld) and (ii) without obtaining (a) a release with respect to
such claim or demand and (b) the dismissal with prejudice of any litigation or
other proceeding with respect to such claim or demand, in each case for the
benefit of and in form and substance reasonably satisfactory to the Indemnified
Party. If the Indemnifying Party elects not to defend the Indemnified Party
against such claim or demand, whether by not giving the Indemnified Party timely
notice as provided above or otherwise, then the amount of any such claim or
demand, or, if the same be contested by the Indemnified Party, then that portion
thereof as to which such defense is unsuccessful (and the reasonable costs and
expenses pertaining to such defense) shall be the liability of the Indemnifying
Party hereunder, subject to the limitations set forth in Section 7.6 hereof. To
the extent the Indemnifying Party shall control or participate in the defense or
settlement of any third party claim or demand, the Indemnified Party will give
to the Indemnifying Party and its counsel access to, during normal business
hours, the relevant business records and other documents, and shall permit them
to consult with the employees and counsel of the Indemnified Party. The
Indemnified Party shall use its commercially reasonable best efforts in the
defense of all such claims.

     7.5      ADJUSTMENTS TO LOSSES.

     The amount of any Loss entitling a party to indemnification under this
Article 7 shall be reduced by (i) the amount of any insurance proceeds actually
recovered by the Indemnified Party for such Loss, net of all costs and expenses
incurred in collecting such

insurance proceeds (including, without limitation, reasonable attorneys'
fees) and (ii) the net tax benefit realized by the Indemnified Party in
connection with the Loss as a result of any reduction in taxable income
resulting from the deduction of the Loss.

     7.6      LIMITATION ON INDEMNIFICATION BY SELLER.

     In no event shall Seller be liable to any Buyer Indemnified Party for
any indemnity claim under Section 7.1(i) or (ii) (except for claims made for
breaches of the representations and warranties in Sections **** or for
breaches of the covenants and indemnities in Sections **** and **** which in
each case shall not be subject to any threshold) unless and until all such
claims for which indemnification is recoverable hereunder by all Buyer
Indemnified Parties exceed in aggregate **** of the **** (the "Threshold");
at which time Seller shall be liable for all Losses which are the subject of
such claims, including those within the Threshold.

     Notwithstanding anything to the contrary herein, in no event shall
Seller be liable to Buyer Indemnified Parties for any claims made under
Section 7.1(i) or (ii) (except for claims made for breach of the
representations and warranties in Sections **** and the covenants in Sections
**** in an aggregate amount that exceeds **** of the ****. Any increase or
decrease to the **** pursuant to Section **** shall be deemed to have no
effect on the previous sentence.

     7.7      LIMITATION ON INDEMNIFICATION BY BUYER

     In no event shall Buyer be liable to Seller Indemnified Parties for any
indemnity claim under Section 7.2(i) or (ii) (except for claims under
Sections **** unless and until all such claims for which damage are
recoverable hereunder by Seller Indemnified Parties exceed the Threshold at
which time Buyer shall be liable for all Losses which are the subject of such
claims, including those within the Threshold. Notwithstanding anything to the
contrary herein, in no event shall Buyer be liable to Seller Indemnified
Parties for any claims made under Section 7.2(i) or (ii) (except for claims
under Sections **** in an aggregate amount that exceeds **** of the ****.

     7.8      EXCLUSIVE REMEDY.

     This Article 7 and Sections 4.9(a), (b) and (c) shall be the exclusive
remedies of the parties hereto for damages under this Agreement and shall be
deemed to preclude the exercise of any other rights and the pursuit of other
remedies (whether in contract, tort or otherwise) in damages for the breach (or
alleged breach) of any representation, warranty, covenant or agreement contained
herein or made pursuant hereto (excluding the Ancillary Agreements); provided,
however, that these exclusive remedies for damages will not be construed to
preclude a party from bringing an action for specific performance or other
equitable remedy to require the other parties to perform its or their
obligations under this Agreement.

     7.9      TREATMENT OF PAYMENTS.

     All payments made pursuant to this Article 7 and Sections 4.9(a) and (c)
shall be treated as adjustments to the purchase price for the Stock.
Notwithstanding anything in this Agreement to the contrary, neither Buyer nor
Parent shall be indemnified or reimbursed for any tax consequences arising from
the receipt or accrual of an indemnity payment hereunder, including, without
limitation, any such consequences arising from adjustments to the basis of any
asset resulting from an adjustment to the Purchase Price, or any additional
Taxes resulting from any such basis adjustment.

schedules need not be attached to each copy of this Agreement. This Agreement,
together with such schedules and exhibits, and the Confidentiality Agreement
constitutes the entire agreement among the parties pertaining to the subject
matter hereof and supersedes all prior agreements and understandings of the
parties in connection therewith. The inclusion of any matter in any schedule to
this Agreement shall be deemed to be an inclusion for all purposes of this
Agreement, including each representation to which it may relate, but shall
expressly not be deemed to constitute an admission by Seller, or otherwise
imply, that any such matter is material for the purposes of this Agreement.

     8.3      BEST EFFORTS; FURTHER ASSURANCES.

     (a) COMMITMENT TO BEST EFFORTS. Subject to the rights of Seller or Buyer,
as the case may be, under Section 6.1, (i) each party hereto shall use its best
efforts to cause all conditions to its obligations hereunder to be timely

     (b) LIMITATION. As used in this Agreement, the term "best efforts" shall
not mean efforts which require the performing party to do any act that is
commercially unreasonable under the circumstances, to make any capital
contribution or to expend any funds other than in payment of reasonable
out-of-pocket expenses incurred in satisfying obligations hereunder, including

transfer shall release Buyer from liability for any breach by any transferee.

Agreement are for convenience only and do not constitute a part of this
Agreement.

     8.14     DISPUTE RESOLUTION.

     (a) All disputes that may arise under or in relation to this Agreement
between either party hereto, that cannot be resolved amicably between the
parties within thirty (30) days of written notice of such dispute, shall be
submitted to arbitration in Tokyo, Japan under the Commercial Arbitration Rules
of the Japan Commercial Arbitration Association (the "JCAA").

     (b) The arbitral tribunal for any such arbitration shall be comprised of
three arbitrators. Each of the claimant and respondent shall nominate one
arbitrator (provided that Buyer and Parent shall together only be permitted to
nominate one arbitrator). If either party fails to nominate an arbitrator in
accordance with the Commercial Arbitration Rules of the JCAA, such arbitrator
shall be appointed by the JCAA. The two arbitrators so nominated shall nominate
the third arbitrator. If for any reason an arbitrator resigns, is removed or
otherwise is no longer serving on the arbitral tribunal, his or her replacement
must be nominated in accordance with the Commercial Arbitration Rules of the
JCAA by the party originally nominating him or her. Any failure by a party to
appoint such replacement shall cause the replacement arbitrator to be appointed
by the JCAA.

     (c) Where any remedy at law or damages is inadequate for any particular
dispute, and without prejudice to the power of arbitrators to award any specific
performance or injunctive or similar equitable relief, any legal action for
specific performance or injunctive or similar equitable relief against either
party may be brought in any court of competent jurisdiction by either party.

     (d) Neither the existence of any dispute, controversy or claim nor the fact
that any arbitration is pending thereunder shall relieve any party of its
respective obligations under this Agreement.

     (e) Judgment upon awards or orders for enforcement may be entered by all
courts to which an award is presented.

     (f) The unsuccessful party in an arbitration shall pay and discharge all
costs and expenses (including reasonable attorneys' fees) which are incurred by
the other party in enforcing this Agreement.

     (g) Any arbitration under this Section 8.14 shall be conducted in English.

     8.15     PARENT GUARANTY

     (a) Parent hereby irrevocably and unconditionally agrees to guaranty to
Seller, jointly and severally with Buyer, the performance by Buyer of its
obligations under the terms of this Agreement, including but not limited to the
obligation to pay the Purchase Price and to repay the Intercompany Loan
hereunder. In the event that all or any portion of the obligations is paid or
performed by Buyer, the obligations of Parent hereunder shall continue and
remain in full force and effect or be reinstated, as the case may be, in the
event that all or any part of such payment is rescinded or recovered directly or
indirectly from Seller as a preference, fraudulent transfer or otherwise, and
any such payment or performance that is rescinded or recovered shall also
constitute obligations.

     (b) Seller shall not be required to give any notice to, or make any demand
on, the Buyer or to proceed against the Buyer's assets prior to the performance
by the Parent of its obligations under this Section 8.15. The Parent agrees that
the Parent's obligations under this Section 8.15 will not be discharged except
by complete performance of all obligations set forth in this Agreement.

     (c) Parent hereby agrees, in furtherance of the foregoing and not in
limitation of any other right which the Seller may have against the Parent by
virtue hereof, that upon the failure of Buyer to pay or perform any of the
obligations when and as the same shall become due hereunder, Parent will, upon
demand, pay, perform or cause to be paid or performed all obligations then due
as aforesaid.

     (d) Parent agrees that it will not exercise any rights of indemnification
or subrogation which it may have under or by virtue of any contract or law
against the Buyer, as a result of or in relation to the performance of the
obligations of the Parent hereunder, unless and until the guarantied amounts
have been paid in full and all obligations have been performed in full.

     (e) Parent agrees to pay, or cause to be paid, on demand, and to indemnify
Seller from and against liability for, any and all costs and expenses (including
reasonable fees and disbursements of counsel) incurred or expended by Seller in
connection with the enforcement of or preservation of any rights under this
Section 8.15.

     (f) The rights, powers and remedies given to Seller by this Section 8.15
are cumulative and shall be in addition to and independent of all rights, powers
and remedies given to Seller by virtue of any statute or rule of law. Any
forbearance or failure to exercise, and any delay by Seller in exercising, any
right, power or remedy hereunder shall not impair any such right, power or
remedy or be construed to be a waiver thereof, nor shall it preclude the further
exercise of any such right, power or remedy.
