            figures for the preceding Fiscal Quarter, for the corresponding
            Fiscal Quarter of the preceding Fiscal Year and for the budget for

            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

8.5   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 partnership at all times, 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.

8.6   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.

9.    UNITS OF CONTRIBUTION; DISPOSITION OF UNITS

9.1   Restrictions on Transfer of Units.

(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 one (1) 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 FP Operative
      Document to which the transferring Unitholder is a party (except to the
      extent the express terms of the Patent Indemnification Agreement condition
      its transferability on the consent of the non-transferring Unitholder and
      such Unitholder has not consented to Transfer thereof), 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 FP
      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 9.1.

                                       21



(b)   If a Unitholder Transfers its entire interest in the Company pursuant to
      Section 9.1(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 Section 6
            or 11 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;

      (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 9.1(a) 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.

9.2   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 all of a Unitholder's Units to an
      Affiliate of such Unitholder in accordance with Section 9.1(a)
      (Restrictions on Transfer of Units), such Person, the terms and conditions
      of such Person's admission as a Unitholder and the

                                       22



      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 and a non-transferring Unitholder
      may reasonably deem appropriate to affirm that the representations and
      warranties contained in the 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 9.1 (Restrictions on Transfer of
      Units) or this Section 9.2.

9.3   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).

9.4   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 Section 11
      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.

10.   CERTAIN AGREEMENTS OF THE UNITHOLDERS

10.1  Taxes and Charges; Governmental Rules. Each Unitholder shall (a) promptly
      pay all applicable Taxes and other governmental charges imposed against
      such Unitholder 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.

10.2  Further Assurances. Following the Closing, each Unitholder shall, and
      shall cause its Affiliates and the Company to take all reasonable actions
      necessary or appropriate to, effectuate the transactions contemplated by
      this Agreement, and to obtain (and cooperate

                                       23



      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.

10.3  Dispute Resolution; Deadlock.

(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 5.1(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 10.3(c), (e)
      and (f) shall apply.

(b)   If (i) the Unitholders are unable to agree on any matter requiring the
      approval of the Unitholders pursuant to Section 4.1(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 5.1(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 10.3(c), (e) and
      (f)) or (iii) the Unitholders or 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 10.3(c), (e) and (f)), then any Unitholder may bring
      the matter to the attention of the General Manager Memory Division,
      Semiconductor Company of Toshiba, and the Chief Operating Officer of
      SanDisk (the "Designated Individuals"), who will attempt to find a
      resolution. If the matter has not been resolved within thirty (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 10.3(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 2.5 of
      the Appendix A. 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 10.3(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)   Except as provided below, if by [***] of any calendar year during the term
      of this Agreement, commencing [***], 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

SEPARATELY WITH THE COMMISSION PURSUANT TO RULE 24B-2. CONFIDENTIAL TREATMENT
HAS BEEN REQUESTED WITH RESPECT TO THE OMITTED PORTIONS.

                                       24



      decision shall be final and binding on the Company and the Unitholders. If
      a decision is reached by 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"), except with respect to any issue where
      the Master Agreement expressly prohibits declaration of a Deadlock.

(d)   If demand for both Unitholder's NAND Flash Memory Products is
      significantly below expectations, they shall address the matter as
      contemplated in Section 6.5(b)(ii) of the Master Agreement.

(e)   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 equal to the
      [***] as of the date of such transaction multiplied by the Initiating
      Unitholder's Percentage as of such date.

(f)   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 10.3 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 11.1(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.

10.4  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 FP 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,

      such transaction multiplied by the Defaulting Unitholder's Percentage as
      of such date; and/or

(b)   elect to dissolve the Company pursuant to Section 11.3 (Dissolution Upon
      Event of Default), in which case the affairs of the Company shall be wound

      (Dispute Resolution; Deadlock), 10.4 (Remedies Upon Event of Default;
      Termination on Breach), 11.4 (Dissolution by Unilateral Option) or 11.5

      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 FP Secondees 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 10.3 (Dispute Resolution; Deadlock), 10.4 (Remedies
      Upon Event of Default; Termination on Breach), 11.4 (Dissolution by

      shall be obligated to take all actions required of it to consummate the
      applicable purchase and sale on the date determined pursuant to this
      Section 10.5 (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.

      agreed by the Unitholders in good faith paid on the closing of such
      transaction and any true-up payment made by the appropriate Party promptly
      after determination of the actual [***] of the Company as of the closing
      of such purchase and sale transaction).

(b)   [***]

(c)   If pursuant to Section 6.10(d)(ii) of the Master Agreement either Party,
      as the Non-Defaulting Party, exercises its election to terminate this
      Agreement, the Non-Defaulting Party shall have the same rights as provided
      in Section 11.6(a) and the Unitholders shall cooperate in good faith to
      effect the purchase by the Non-Defaulting Party (or its designated
      Affiliate) and sale by the Defaulting Party of all of the Defaulting
      Party's Units.

11.7  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, (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 FP
      Operative Document or to offer to enter into any other agreement with a

      purchaser of the Company for the purchase or sale of goods or services or
      the use of facilities or any other business arrangement), and (iii)
      distribute any net proceeds to the Unitholders in accordance with Section
      11.8 hereof and applicable Law. 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 11.3 (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.

(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.

11.8  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 6.2 (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 11.8, 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 11.8 shall be made as soon
      as practicable under and in accordance with applicable Japanese law.

12.   INDEMNIFICATION AND INSURANCE

12.1  Indemnification.

                                       29


(a)   Subject to Section 12.1(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, 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 12.1 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 12.1 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 12.1 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 12.1, 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 FP Secondee 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 12.1(c) (Indemnification).

                                       30


12.2  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 12.1.

12.3  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.

(b)   The provisions of this Section 12.3 shall survive each of the termination
      of this Agreement, the dissolution of the Company and the withdrawal of
      any Unitholder.

12.4  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 Section 12, 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
      Unitholders 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.

                                       31
