          SECTION 6.01  Capital Contributions.

               (a)  The Unitholders shall be deemed to have made Capital

shall be made in proportion to the Unitholders' respective Percentages as of the
date of such additional Capital Contribution.

          SECTION 6.02  Distributions.

               (a)  General. Notwithstanding any provision of the Articles to
the contrary, and subject to Section 11.07 (Liquidation Proceeds), unless
otherwise agreed by the Unitholders, no distributions of cash (or in the case of
Section 11.07 (Liquidation Proceeds), other property) shall be made by the
Company to the Unitholders for a period of three (3) years from the date of this
Agreement, and thereafter all distributions of cash (or, in the case of Section
11.07 (Liquidation Proceeds), other property) by the Company to the Unitholders
shall be made in Japanese Yen at the times and in the amounts determined by the
Unitholders. Except as provided in Section 11.07 (Liquidation Proceeds), each
distribution to the Unitholders shall be made on a pro rata basis based upon the
respective Percentages of the Unitholders as of the date of such distribution.

               (b)  Distribution for Taxes. Notwithstanding the provisions of
Section 6.02(a), the Company shall make, in respect of each Fiscal Year in which
SanDisk must recognize taxable income of the Company in SanDisk's US federal,
state and local income and franchise tax returns, a distribution to SanDisk to
the extent necessary to meet SanDisk's aggregate US tax liability with respect
to such taxable income, with such liability calculated at the highest US, state
and local corporate tax rates as may be then applicable to SanDisk. SanDisk will
make a request upon the Company for such distribution as soon as is practicable
after the filing of SanDisk's applicable US tax returns. Following receipt of
such request, the

                                       17



Company shall make the requested distribution on the next date on which the
Company is permitted to make distributions pursuant to the Japan Act.
Simultaneously therewith, the Company shall also make a distribution to Toshiba
in an amount equal to the amount of the distribution made to SanDisk pursuant to
this Section 6.02(b). Any such prior distributions shall be taken into account
upon any purchase and sale of Units under Article X herein or dissolution of the
Company under Article XI herein.

          SECTION 6.03  No Interest. No interest shall be payable to the
Unitholders on their Capital Contributions or otherwise in respect of the
capital of the Company.

          SECTION 6.04  Return of Capital Contributions. Except as expressly

          SECTION 8.02  Maintenance of Books of Account. The Company shall keep

          SECTION 8.03  Financial Statements.

               (a)  Annual Statements. As soon as practicable following the end

Unitholder and each Director, audited consolidated and consolidating balance
sheets of the Company as of the end of such Fiscal Year and the related audited
consolidated and consolidating statements of operations, the Unitholders'
capital accounts and cash flows of the Company for such Fiscal Year (or similar
statements if such statements change as the result of changes in Japanese GAAP),
together with appropriate notes to such consolidated financial statements, and
in each case setting forth in comparative form the corresponding figures for the
preceding Fiscal Year and for the budget for the Fiscal

                                       18



Year just completed. Such financial statements shall be accompanied by (i) the
report of the Accountants to the effect that such financial statements (except

GAAP (except as otherwise specified in such report) and that the audit of such
financial statements has been performed in accordance with Japanese GAAP and
(ii) a report as to all transactions (including the nature, type and amount)
between the Company and each Unitholder and their respective Affiliates. The
Company shall conduct its business such that the report of the Accountants shall
not contain any qualifications as to the scope of the audit or with respect to
the Company's compliance with Japanese GAAP, except for changes in methods of
accounting in which such Accountants concur and except that the foregoing shall
not be deemed to obligate any Unitholder to contribute any capital to the
Company. The Company shall deliver to SanDisk, at SanDisk's request and expense,
any other financial information related to the Company that is reasonably
requested by SanDisk for US Federal, state, and local income or franchise tax
purposes.

Quarter and for the Fiscal Year to date (or similar statements if such
statements change as the result of changes in Japanese GAAP), in each case
setting forth in comparative form the corresponding figures for the preceding
Fiscal Quarter, for the corresponding Fiscal Quarter of the preceding Fiscal
Year and for the budget for the Fiscal Quarter just completed and for the Fiscal
Year to date. Such financial statements shall be accompanied by a certificate of
the principal accounting or financial officer of the Company to the effect that
such financial statements have been prepared under such officer's supervision
and that, although such financial statements do not contain the footnotes and
other disclosures required to be presented in interim financial statements by
Japanese GAAP, such financial statements, in such officer's judgment, fairly
present the financial condition and results of operations of the Company as of
the date and for the periods indicated, subject to normal recurring year-end
audit adjustments. The Company shall deliver to SanDisk, at SanDisk's request
and expense, any other financial information related to the Company that is
reasonably requested by SanDisk for US Federal, state, and local income or
franchise tax purposes.

               (c)  Monthly Reports. Each month, the Company shall prepare and

Business Plan, including the Company's monthly budgets, for the upcoming Fiscal

        SECTION 8.04  Other Reports and Inspection. The Company shall furnish
promptly to each Unitholder such other reports, financial data and information
relating to the Company as such Unitholder may reasonably request and shall
require the Accountants to provide to each Unitholder copies of any document
related to the Company in the possession of the Accountants as such Unitholder
may reasonably request. The Company shall, upon reasonable prior notice and
during normal business hours, make available to each Unitholder and their
respective professional advisors, from time to time as requested by such
Unitholder, all properties, assets, books of account, corporate records,
contracts and documentation, if any, relating to employee benefits of the
Company, and any other material requested by such Unitholder for inspection and,
in the case of books of account, corporate records, contracts and documentation,
if any, relating to employee benefits, copying, and shall use reasonable efforts
to make available to such Unitholder the Accountants and the key employees of
the Company for interviews to verify any information furnished or to enable such
Unitholder otherwise to review the Company and its operations. The Company may
condition such availability upon the entering into of reasonable and appropriate
confidentiality agreements. Notwithstanding the foregoing, the Company will not
make available to any Unitholder information provided to the Company on a
confidential basis by any other Unitholder without the consent of such other
Unitholder.

        SECTION 8.05  Characterization. For the purposes of US federal, state
and local income and franchise taxation, the Unitholders intend that the Company
shall be treated as a disregarded entity at all times during the Transition
Period and as a partnership at all times following the expiration of the
Transition Period, and shall take all actions, including the execution of other
documents required to be filed by the Code, as may be reasonably required to
qualify for and receive treatment as a disregarded entity and as a partnership,
as the case may be, for such US tax purposes. SanDisk shall bear all costs and
expenses incurred by the Company or any Unitholder in connection with any action
required to be taken pursuant to this Section. Notwithstanding the foregoing,
the Company shall have no obligation to take any action under this Section that
would have an adverse effect on it or any Unitholder under any Japanese
Governmental Rule.

        SECTION 8.06  Deposit of Funds. All funds of the Company and its
Subsidiaries not otherwise employed shall be deposited from time to time to its
credit in such banks, trust companies or other depositories, or invested in such
other investments held as cash equivalents, as the Board of Directors shall
authorize. The funds of the Company and its Subsidiaries shall not be commingled
with the funds of any Unitholder or any of their respective Affiliates.

                                   ARTICLE IX

                   Units of Contribution; Disposition of Units

        SECTION 9.01  Restrictions on Transfer of Units.

                                       20



               (a)  No Unitholder (nor any permitted transferees of any
Unitholder) may Transfer any interest in the Company, including any of such
Unitholder's Units, to any Person, except by a Change of Control; provided, that
any Unitholder may Transfer all of its interest in the Company, including all of
its Units, to any of their respective Affiliates, with the prior written consent
of every other Unitholder, which consent shall not be unreasonably withheld; and
provided, further, that (i) the transferee agrees in writing to become a party
hereto and assumes all the obligations of the transferring Unitholder hereunder
and under each other Operative Document to which the transferring Unitholder is
a party and (ii) immediately after giving effect to such Transfer, no Event of
Default or an event or condition that with the giving of notice or lapse of time
or both would constitute an Event of Default with respect to the transferee
Unitholder shall exist. Following the effectiveness of any such Transfer, the
transferring Unitholder shall no longer have the transferred right, title or
interest in the Company or any rights under this Agreement and the transferee
shall be substituted as a Unitholder for all purposes of this Agreement. The
transferring Unitholder shall, however, remain responsible for all obligations
under this Agreement and the other Operative Documents for any transferee which
is an Affiliate of the transferring Unitholder and shall not be released or
discharged from any existing liability or obligation to any Person. Any
subsequent Transfer of an ownership interest in such Affiliate by the
transferring Unitholder shall be deemed to constitute a Transfer of Units
requiring compliance with this Section 9.01.

               (b)  If a Unitholder Transfers its entire interest in the Company
pursuant to Section 9.01(a), the transferee shall succeed to all the rights and
obligations of such Unitholder under this Agreement.

               (c)  Any Unitholder may agree to pay amounts equal to
distributions received by such Unitholder from the Company to a third party in
its sole discretion pursuant to a Permissible Assignment Agreement. "Permissible
Assignment Agreement" means an agreement between a Unitholder and another Person
(the "Permissible Assignee") which:

                    (i)   provides for the grant by such Unitholder to the
          Permissible Assignee of the right to receive amounts equal to
          distributions received by such Unitholder from the Company pursuant to
          Article VI or XI of this Agreement, but does not give the Permissible
          Assignee any Units or any other rights whatsoever with respect to the
          Company;

                    (ii)  provides that under no circumstances (including any
          Bankruptcy Event in respect of such Unitholder) may any claim be made
          by the Permissible Assignee against the Company or any such Unitholder
          or any Affiliate of any such Unitholder or any of their respective
          assets, under or in connection with such agreement, even if such
          Unitholder defaults in performance thereunder;

                    (iii) provides that the rights of the Permissible Assignee
          under such agreement may not be transferred without the prior written
          consent of each Unitholder and that any such Transfer without such
          consents shall be null and void;

                                       21



                    (iv) may not be amended, nor any provision thereof waived,
     in a manner that would cause it not to be a Permissible Assignment
     Agreement, without the prior written consent of the non-assigning
     Unitholder;

                    (v)  provides that the assigning Unitholder is authorized to
     Transfer its entire interest in the Company pursuant to Section 9.01(a) of
     this Agreement free and clear of any interest of the Permissible Assignee
     and without any liability on the part of the transferee thereunder to the
     Permissible Assignee; and

                    (vi) contains an express acknowledgment by the Permissible
     Assignee, for the benefit of the non-assigning Unitholder and the Company,
     to the effect of clauses (i)-(v) above.

          The assigning Unitholder shall ensure that any payment due to a
Permissible Assignee pursuant to or in connection with a Permissible Assignment
Agreement shall be made in full to such Permissible Assignee when due.

          SECTION 9.02  Admission of New Unitholders. No Person shall have the
right to become a Unitholder unless and until all the following conditions are
satisfied:

               (a)  except in the case of a Transfer of a Unitholder's Units to
an Affiliate of such Unitholder in accordance with Section 9.01 (Restrictions on
Transfer of Units), such Person, the terms and conditions of such Person's
admission as a Unitholder and the rights appurtenant to the Units to be issued
or Transferred, as applicable, to such Person are approved by all existing
Unitholders and, if applicable, the creation of any new class or group of Units
in the Company having different rights, powers and duties is reflected in
amendments to the Articles and to this Agreement;

               (b)  such Person executes a counterpart of this Agreement and
such other instrument or instruments as the Company may reasonably deem
appropriate to affirm that the representations and warranties contained in the
New Master Agreement are true and correct with respect to such Person and that
such Person agrees to be bound as a Unitholder by this Agreement and all of the
covenants and agreements herein; and

               (c)  if requested by the Company, an opinion of counsel, a
purchaser representation letter or other appropriate documentation is furnished
to the Company establishing that the issuance or Transfer, as applicable, of
Units to the new Unitholder will comply with the Japan Act.

          Except to the extent required by law, the Company shall have no
obligation to recognize or to furnish information or make distributions to any
new Unitholder or any transferee of a Unitholder who does not become a
Unitholder in accordance with Section 9.01 (Restrictions on Transfer of Units)
or this Section 9.02.

          SECTION 9.03  Withdrawal Prohibited. Except as otherwise expressly
permitted by this Agreement, (i) no Unitholder may withdraw from the Company and
(ii) no Unitholder may effect or cause a termination or dissolution of the
Company without the prior

written consent of all other Unitholders (which consent may be withheld in such
other Unitholder's sole discretion).

          SECTION 9.04   Purchase of Additional Interest. At any time during the
term of this Agreement and so long as SanDisk is a Unitholder, SanDisk shall
have the right to purchase from Toshiba that number of Units which is equal to
0.1% of the total number of Units then issued and outstanding in the event that
(i) Toshiba's patent umbrella does not adequately protect the Company or (ii)
dissolution of the Company is commenced pursuant to Article XI hereof. The
purchase price of such Units shall equal 0.1% of the Company's Net Book Value as
of the date of such transaction.

                      Certain Agreements of the Unitholders

          SECTION 10.01  (Intentionally Blank)

          SECTION 10.02  Taxes and Charges; Governmental Rules. Each Unitholder
shall (a) promptly pay all applicable Taxes and other governmental charges
except to the extent any such Taxes or other charges are being contested in good
faith by appropriate proceedings and (b) comply with all applicable Governmental
Rules, in each case except to the extent that nonpayment or noncompliance will
not have a material adverse effect on the Company.

          SECTION 10.03  Further Assurances. Following the Closing, each
Unitholder shall, and shall cause its Affiliates, FVC and the Company to take
all reasonable actions necessary or appropriate to, effectuate the transactions
contemplated by this Agreement, and to obtain (and cooperate with the other
Unitholder in obtaining) any Governmental Action or third party consent required
to be obtained or made by it in connection with the transactions contemplated by
this Agreement; provided, that no Burdensome Condition shall be made to exist
with respect to such Unitholder or any of its Affiliates in connection
therewith.

          SECTION 10.04  Dispute Resolution; Deadlock Respecting Business Plan.

               (a)  The Unitholders shall endeavor to settle, through their
respective designees to the Board of Directors, any disputes which may arise
between them, including without limitation, failure by the Board of Directors to
reach agreement (or failure to take a vote) on any matter requiring Board of
Directors approval pursuant to Section 5.01(d) (Matters Requiring the Approval
of the Board of Directors). The Unitholders shall attempt to resolve the issue
or proposed action in question, to the extent practicable, in a manner
consistent with the Company's most recently approved Business Plan, unless the
issue in dispute is the adoption of a new Business Plan, in which case the
provisions of Sections 10.04(c), (d) and (e) shall apply.

               (b)  If (i) the Unitholders are unable to agree on any matter
requiring the approval of the Unitholders pursuant to Section 4.01(a) (Matters
Requiring the Approval of the Unitholders ), (ii) the Board of Directors is
unable to agree on any matter requiring the approval of the Board of Directors
pursuant to Section 5.01(d) (Matters Requiring the Approval of the Board of
Directors) (other than the approval of any Business Plan, with respect to which
the failure to agree shall be governed by Sections 10.04(c), (d) and (e)) or
(iii) the Unitholders or

                                       23



the Board of Directors are otherwise unable to resolve a dispute on any other
item (other than the approval of any Business Plan, with respect to which the
failure to agree shall be governed by Sections 10.04(c), (d) and (e)), then any
Unitholder may bring the matter to the attention of the Vice President,
Semiconductor Company of Toshiba, and the SanDisk General Manager, NAND Division
(the "Designated Individuals"), who will attempt to find a resolution. If the
matter has not been resolved within 30 days of referral to the Designated
Individuals, the matter will be referred to the Management Committee for a final
decision, which decision will be final and binding on the Company and the
Unitholders with respect to any matter specified in Sections 10.04(b)(i) and
(ii) above. If an agreement is reached by the Management Committee, the mutually
agreed resolution shall be implemented by the Company. Should no solution be
agreed upon within thirty (30) days after submission of the matter to the
Management Committee with respect to the matters specified in (iii) above, such
matter shall be submitted to arbitration in accordance with Section 10.03(b)
(Dispute Resolution) of the New Master Agreement. Should no solution be agreed
upon within sixty (60) days after submission of the matter to the Management
Committee with respect to the matters specified in Sections 10.04(b)(i) and (ii)
above, then the action for which approval was requested will not occur, unless
it is already included in the most recently approved Business Plan.

               (c)  If by February 15 of any calendar year during the term of
this Agreement, commencing February 15, 2004, the Board of Directors and the
Unitholders have not approved and agreed upon a Business Plan for the upcoming
Fiscal Year, then any Unitholder may refer the dispute to the Management
Committee for a decision, which decision shall be final and binding on the
Company and the Unitholders. If a decision is reached by mutual agreement of the
Management Committee, such decision shall be implemented by the Company. Should
no decision be reached within ninety (90) days after submission of the matter to
the Management Committee, and unless the Unitholders have agreed to continue
operations under the most recently approved Business Plan until a new Business
Plan is approved, then within ten (10) Business Days thereafter any Unitholder
may elect by written notice to all other Unitholders to declare a deadlock
("Deadlock").

               (d)  Within thirty (30) days after a Unitholder has notified the
other Unitholder of a Deadlock, either Unitholder (the "Initiating Unitholder")
may submit to the other Unitholder (the "Responding Unitholder") a written
irrevocable notice (the "Deadlock Dissolution Notice") to the effect that the
Initiating Unitholder offers to sell to the Responding Unitholder or its
designee the Initiating Unitholder's Units for a cash payment, by wire transfer
of immediately available Japanese Yen, in an amount [***] of the Company as of
the date of such transaction multiplied by the Initiating Unitholder's
Percentage as of such date.

               (e)  The Responding Unitholder may accept such offer by written
response to the Initiating Unitholder within forty-five (45) days of receipt of
the Deadlock Dissolution Notice indicating that the Responding Unitholder elects
to purchase the Units of the Initiating Unitholder. If the Responding Unitholder
declines to exercise its right to purchase the Units of the Initiating
Unitholder pursuant to this Section 10.04 or fails to respond to such Deadlock
Dissolution Notice (or if both Unitholders submit Deadlock Dissolution Notices),
the Company shall be dissolved pursuant to Section 11.01(d) (Events of
Dissolution), at the end of a one-year period for the wind-down of operations
commencing with the receipt of the Deadlock Dissolution Notice by the Responding
Unitholder. During such one-year period, the Company's business shall be
conducted in accordance

with the most recently approved Business Plan except that additional capital
expenditures will not be made except as required for line maintenance.

          SECTION 10.05  Remedies Upon Event of Default; Termination on Breach.
If there has occurred and is continuing an Event of Default with respect to a
Unitholder (upon such occurrence, such Unitholder is referred to herein as the
"Defaulting Unitholder"), in addition to all other remedies available to the
Company or the other Unitholder (the "Nondefaulting Unitholder"), whether under
any of the Operative Documents or other agreements or by law, the Nondefaulting
Unitholder shall have the option to take one or more of the following actions:

               (a)  give written notice to the Defaulting Unitholder of its
intention to acquire all of the Units of the Defaulting Unitholder for a cash
payment, by wire transfer of immediately available Japanese Yen, in an amount
equal to the Net Book Value of the Company as of the date of such transaction
multiplied by the Defaulting Unitholder's Percentage as of such date; and/or

               (b)  elect to dissolve the Company pursuant to Section 11.03
(Dissolution Upon Event of Default), in which case the affairs of the Company
shall be wound up and the Company shall be dissolved in accordance with Article

(Dissolution by Unilateral Option) or 11.05 (Dissolution Upon Notice) shall take
place not later than the [***] Business Day after notice of the purchase is
given, as the case may be, except that such period shall be extended as
necessary in order to comply with any Governmental Rule. The purchasing
Unitholder shall pay for the Units being acquired by wire transfer of
immediately available funds in Japanese Yen to an account specified by the
selling Unitholder. The selling Unitholder shall execute all documents necessary
to effect the conveyance of its Units, free and clear of all Liens, to the
purchasing Unitholder. In addition, the Unitholders shall enter into an
indemnity and release agreement, in a form reasonably satisfactory to each
Unitholder, indemnifying and holding harmless the selling Unitholder and its
Affiliates for liabilities or claims made after the date of the purchase and
sale under any guarantees or other agreements supporting the obligations of the
Company which may have been extended by the selling Unitholder or any of its
Affiliates. The Unitholders shall also reach agreement on a reasonable
transition plan of up to six months in connection with services provided to the
Company by Seconded Employees assigned to the Company by the Selling Unitholder.

               (b)  If a Unitholder elects to acquire all of the Units of the
other Unitholder pursuant to Section 10.04(e) (Dispute Resolution; Deadlock
Respecting Business Plan), 10.05(a) (Remedies Upon Event of Default; Termination
on Breach), 11.04 (Dissolution by Unilateral Option) or 11.05 (Dissolution Upon
Notice), such Unitholder shall be obligated to take all actions required of it
to consummate the applicable purchase and sale on the date

determined pursuant to Section 10.07(a) (Mechanics of Sale). If any Unitholder
has the right to purchase the Units of any other Unitholder, such Unitholder
shall have the right to assign such right to purchase to any other Person.

                                   ARTICLE XI

                                   Dissolution

either (i) the Responding Unitholder declines to exercise its right to purchase
the Units of the Initiating Unitholder or fails to respond to such Deadlock
Dissolution Notice, or (ii) both Unitholders submit Deadlock Dissolution Notices
with respect to such failure to agree;

               (e)  the election by Toshiba to dissolve the Company pursuant to

Event) with respect to a Unitholder, the Nondefaulting Unitholder may elect, by
written notice to the Defaulting Unitholder, to dissolve the Company, in which
event the Company shall be dissolved and the Unitholders shall take all actions
necessary to wind up the affairs of the Company in accordance with Section 11.06
(Winding Up). This Section 11.03 shall not be construed to limit the rights of
the

                                       26



Nondefaulting Unitholder under Section 10.05 (Remedies Upon Event of Default) or
to seek damages from the Defaulting Unitholder or any other Person for the
breach of its obligations under any of the Operative Documents.

          SECTION 11.04  Dissolution by Unilateral Option. At any time between
April 1, 2003 and March 31, 2004, SanDisk may, by giving written notice to
Toshiba, elect to withdraw from the Company, in which case Toshiba must,
directly or through any of its Affiliates, either (i) purchase from SanDisk all
of SanDisk's Units one (1) year following SanDisk's notice to withdraw (the
"Termination Date") for a cash payment, by wire transfer of immediately
available Japanese Yen, in an amount equal to the Net Book Value of the Company
as of the Termination Date multiplied by SanDisk's Percentage as of the
Termination Date, and increased or decreased, as the case may be, for any cash
contributions by or distributions to the Unitholders after the date of the

Company, in which event the Company will be dissolved and, within the one (1)
year period following the giving of such notice, the Unitholders shall mutually
agree upon a plan for winding up the affairs of the Company in accordance with
Section 11.06 (Winding Up), unless the Notified Party, directly or through any

payment, by wire transfer of immediately available Japanese Yen, in an amount
equal to the Net Book Value of the Company as of the date of such transaction
multiplied by the Notifying Party's Percentage as of such date.

          SECTION 11.06  Winding Up.

               (a)  Upon the dissolution of the Company, the Unitholders shall
proceed as promptly as practicable to (i) wind-up the affairs of the Company and
satisfy the Company's liabilities and (ii) dispose of the Company's assets as
quickly as possible consistent with obtaining the full fair market value of the
Company, preferably, to the extent it is commercially practicable to do so, by
selling the Company as a going concern; provided, however, no Unitholder shall
be under any obligation to extend the terms of any Operative Document or to
offer to enter into any other agreement with a prospective purchaser of the
Company for the purchase or sale of goods or services or the use of facilities
or any other business arrangement. In connection with a sale of the Company's
assets under clause (ii), each Unitholder or any of their respective Affiliates
shall have a right of first offer to acquire the Company's tangible personal
property in the liquidation process and may also acquire such property through
participation at auction except in the event of a dissolution pursuant to
Section 11.03 (Dissolution Upon Event of Default), in which event the Defaulting
Unitholder and its Affiliates shall not have such right of first offer to
acquire the Company's tangible personal property. Each of the Unitholders shall
be furnished with a statement setting forth the assets and liabilities of the
Company as of the date of the complete liquidation of the Company. The
Accountants shall review the final accounting and shall render their opinion
with respect thereto.

                                       27



               (b)  During the period of winding-up, the Company shall continue
to operate and all the provisions of this Agreement shall remain in effect,
except as otherwise expressly provided herein. The Company shall notify all
known creditors and claimants of the dissolution of the Company in accordance
with applicable law.

          SECTION 11.07  Liquidation Proceeds.

               (a)  In the case of the dissolution and liquidation of the
Company, the Company may make a distribution in kind. Any cash and all
distributions in kind that are to be distributed shall be distributed to the
Unitholders, on a pro rata basis based upon the respective Percentages of the
Unitholders as of the date of such distribution.

               (b)  Unless otherwise agreed by the Unitholders, and to the
extent permitted under any agreements with third parties, all assets to be
distributed upon the dissolution and liquidation of the Company shall be
distributed as follows:

                    (i)   first, to creditors, including Unitholders who are
     creditors, to the extent permitted by law, in satisfaction of liabilities
     of the Company, other than for distributions to Unitholders pursuant to
     Section 6.02 (Distributions); and

                    (ii)  second, to the Unitholders on a pro rata basis based
     upon the respective Percentages of the Unitholders as of the date of such
     distribution.

For purposes of this Section 11.07, instruments of transfer and other documents
reasonably requested by the distributee shall be executed by the Company or the
other Unitholder, or both.

               (c)  Any distribution made pursuant to this Section 11.07 shall
be made as soon as practicable under and in accordance with applicable Japanese
law.

          SECTION 11.08  Additional Contribution. No Unitholder shall be
obligated to contribute any additional amounts to the Company or otherwise be
liable for the debts and obligations of the Company.

                                  ARTICLE XII

                          Indemnification and Insurance

          SECTION 12.01  Indemnification.

               (a)  Subject to Section 12.01(c), the Company shall indemnify
each Person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (including an action by or in the
right of a Unitholder or the Company), by reason of the fact that such Person is
or was a Unitholder or is or was or has agreed to become a Director or is or was
serving or has agreed to serve at the request of the Company as a director,
officer, employee or agent of the Company or of another partnership,
corporation, joint venture, trust or other enterprise, arising from any action
alleged to have been taken in any such capacity or by reason of any liability or
obligation of the Company, against any and all losses, damages, liabilities,

                                       28



costs, charges, expenses (including interest, penalties and reasonable
attorneys' fees and expenses), judgments, fines and amounts paid in settlement
(collectively, "Losses") actually and reasonably incurred by him or on his
behalf in connection with such action, suit or proceeding and any appeal
therefrom. Without limiting the generality of the foregoing, any of such Losses
shall be deemed to arise out of a Company liability or obligation if it arises
out of or is based upon the conduct of the business of the Company (or any of
its Subsidiaries) or the ownership of the property of the Company (or any of its
Subsidiaries).

               (b)  The indemnification provided under this Section 12.01 shall
inure to the benefit of the successors, heirs and personal representatives of
any Person entitled to the benefit of such indemnification. Such indemnification
shall be a contract right and shall include the right to be paid advances of
reasonable expenses incurred by any such Person in connection with such action,
suit or proceeding.

               (c)  The indemnification provided under this Section 12.01 shall
not inure to the benefit of any Person in respect of Losses to the extent that
such Losses (i) arise out of or are based upon the gross negligence or willful
misconduct of such Person or (ii) constitute a tax, levy or similar governmental
charge not imposed upon the Company (or any of its Subsidiaries) or on their
respective properties. The indemnification provided under this Section 12.01
shall also not be available to any Person in respect of any Losses if a judgment
or other final adjudication adverse to such Person establishes (x) that such
Person's acts were committed in bad faith or were the result of active and
deliberate dishonesty and were material to the cause of action so adjudicated or
(y) that such Person gained in fact a financial profit or other advantage to
which such Person was not legally entitled. It is understood and agreed that,
for the purposes of this Section 12.01, Losses shall be deemed not to arise out
of or be based upon the gross negligence or willful misconduct of a Person
solely because it arises out of or is based upon the gross negligence, willful
misconduct, bad faith or active and deliberate dishonesty of a director, officer
or employee of such Person if at the time of such gross negligence, willful
misconduct, bad faith or active and deliberate dishonesty, such director,
officer or employee was also a Seconded Employee or a Director acting in his
capacity as such.

               (d)  The termination of any action, suit or proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or its
equivalent shall not, of itself, create a presumption that the indemnified
Person did not meet the standard set forth in Section 12.01(c)
(Indemnification).

          SECTION 12.02  Insurance. The Company may, to the fullest extent
permitted by law, purchase and maintain insurance against any liability that may
be asserted against any Person entitled to indemnity pursuant to Section 12.01.

          SECTION 12.03  Indemnification by the Unitholders.

               (a)  Each Unitholder agrees to, and does hereby, indemnify and
hold harmless the Company and the other Unitholder from and against any and all
Losses arising out of, or based upon, the gross negligence or willful misconduct
of such Unitholder under this Agreement or such Unitholder exceeding its
authority under this Agreement.

                                       29



               (b)  The provisions of this Section 12.03 shall survive each of
the termination of this Agreement, the dissolution of the Company and the
withdrawal of any Unitholder.

          SECTION 12.04  Assertion of Claims.

               (a)  In the event that a Person (the "Indemnified Party") desires
to assert its right to indemnification from a Person (an "Indemnifying Party")
required to indemnify such Indemnified Party under this Article XII, the
Indemnified Party will give the Indemnifying Party prompt notice of the claim
giving rise thereto (a "Claim"), and the Indemnifying Party shall undertake the
defense thereof (unless the Claim is asserted against or related to or results
from any action or failure to take action by such Indemnifying Party). The
failure to promptly notify the Indemnifying Party hereunder shall not relieve
the Indemnifying Party of its obligations hereunder, except to the extent that
the Indemnifying Party is actually prejudiced by the failure to so notify
promptly.

               (b)  The Indemnified Party shall not settle or compromise any
Claim without the written consent of the Indemnifying Party unless the
Indemnified Party agrees in writing to forego any and all claims for
indemnification from the Indemnifying Party with respect to such Claim. However,
if the Indemnifying Party, within a reasonable time after notice of any such
Claim, fails to defend such Claim, the Indemnified Party shall have the right to
undertake the defense, compromise or settlement of such Claim on behalf of and
for the account and risk of the Indemnifying Party, subject to the right of the
Indemnifying Party to assume the defense of such Claim at any time prior to
settlement, compromise or final determination thereof.

               (c)  If the Indemnifying Party has undertaken the defense of a
Claim and (i) if there is a reasonable expectation that (x) a Claim may
materially and adversely affect the Indemnified Party other than as a result of
money damages or other money payments or (y) the Indemnified Party or Parties
may have legal defenses available to it or them that are different from or
additional to the defenses available to the Indemnifying Party, or (ii) if the
Indemnifying Party shall not have employed counsel reasonably satisfactory to
the Indemnified Party, the Indemnified Party shall nevertheless have the right,
at the Indemnifying Party's cost and expense, to defend such Claim.

                                  ARTICLE XIII

                                  Miscellaneous

          SECTION 13.01  Governing Law. Notwithstanding anything to the contrary
in the Rules Document, this Agreement shall in all respects be governed by and
construed in accordance with the laws of Japan, without regard to the conflict
of laws principles.

          SECTION 13.02  Effectiveness. Notwithstanding anything to the contrary
in the Rules Document, this Agreement shall be effective as of April 10, 2002.

          SECTION 13.03  Conflict with Articles. In the event of any conflict
between this Agreement and the Articles, the provisions of this Agreement shall
control, and the

                                       30



conflicting provisions of the Articles shall be deemed to have been waived by
the Parties, to the extent permissible under applicable law.
