Each Party shall direct the Consultant retained by it to (i) provide the other Consultant and other Party with its initial environmental report on the Y5 Facility and Other Y5 Facilities and (ii) discuss the reports in good faith with the other Consultant with the intent of the Parties and their Consultants agreeing upon a single, combined report (the "Y5 Baseline Environmental Report"). If Toshiba, SanDisk and the Consultants are unable to agree upon a single report within sixty (60) days after the start of Y5 Facility operations, then the draft reports of both Consultants (or combined report indicating areas of disagreement) shall collectively be considered to be the Y5 Baseline Environmental Report.

4.

Environmental Compliance.

4.1

Compliance. The Parties confirm their intent that the Y5 Facility and Other Y5 Facilities and all operations of the Company be maintained in compliance with all Environmental Laws, including by having remedial measures taken as required by any Governmental Authority or otherwise reasonably necessary to ensure that the Y5 Facility and Other Y5 Facilities and all operations of the Company will remain in compliance with all Environmental Laws.

4.2

Notice. Each Party shall promptly notify the other of any circumstances of which it becomes aware that require or could reasonably be expected to require remediation or other actions to ensure that the Company and its operations are and will be maintained in compliance with all Environmental Laws and to minimize the aggregate Covered Environmental Costs (as defined below) that may be incurred. Upon any such notice being given and received, the Parties shall promptly discuss in good faith and seek to agree upon the measures to be taken in response to such circumstances. Pending their agreement, nothing shall prevent or limit Toshiba, acting in good faith on its own initiative or upon SanDisk153s reasonable request, from investigating the circumstances of any releases of Hazardous Substances or taking steps reasonably appropriate to limit or prevent ongoing releases, to limit the effects of a release, or to prevent or limit any exposure or damage resulting from, arising out of or otherwise by virtue of a release, including taking immediate or urgent steps as appropriate in light of the circumstances then known, provided, that nothing in this paragraph shall require either Party to take any step except as required by applicable Environmental Law.

5.

Indemnification Obligations.

5.1

Mutual Responsibility and Indemnity for Environmental Costs.

(a)

Subject to Section 1425.1(b), each of SanDisk and Toshiba shall:

(1)

be responsible for bearing its Share of Environmental Costs; and

(2)

indemnify, defend and hold harmless the other Party and the Company (and their respective Indemnified Parties) for its Share of such Environmental Costs.

3


(b)

Each of SanDisk153s and Toshiba153s responsibility for its Share of Environmental Costs under Section 1425.1(a) shall be subject to each of the following limitations (Environmental Costs not excluded from the one or both Parties153 responsibility under this Section 1425.1(b), "Covered Environmental Costs"):

(1)

Except as provided in Section 5.2(a), neither Party shall be responsible for conditions identified in the Y5 Baseline Environmental Report, including responsibility for any Environmental Costs resulting from, arising out of or otherwise by virtue of remediation or removal of pre-existing conditions. However, if remedial measures otherwise taken in accordance with this Agreement incidentally result in remediation or removal of conditions not resulting from operation of the Y5 Facility or Other Y5 Facilities, only the Environmental Costs paid for the remedial measures taken with respect to the Y5 Facility or Other Y5 Facilities, as applicable (including amounts paid for remedial measures taken with respect to the Y5 Facility or Other Y5 Facilities that return the Y5 Facility or Other Y5 Facilities to a condition better than that identified in the Y5 Baseline Environmental Report) shall constitute Covered Environmental Costs.

(2)

Neither Party shall be responsible for Environmental Costs to the extent such Environmental Costs are incurred as a result of the willful misconduct of employees, agents or representatives of the other Party.

(3)

Environmental Costs incurred for remediation shall only constitute Covered Environmental Costs to the extent reasonably necessary to ensure that the Company fulfills the Prudent Operator Standard. The "Prudent Operator Standard" means taking all such remedial measures (i) as are required to be in compliance with all then effective Environmental Laws, (ii) that have been required by a Governmental Authority or (iii) that a prudent operator of a similar facility would then take or begin to take to ensure that its continuing operations and facilities will remain in compliance with then effective Environmental Laws and with Environmental Laws as they are then scheduled to go into effect or are anticipated to be changed in the next ****.

(4)

No Environmental Costs shall constitute Covered Environmental Costs with respect to either Party to the extent such Party153s liability limit under Section 1425.5 has been exceeded.

(c)

If the Parties are not able to agree on whether any given Environmental Costs constitute Covered Environmental Costs (including, following the completion of the sixty (60)-day process set forth in Section 1428.5, as to whether remediation is necessary to fulfill the Prudent Operator Standard), such dispute shall be resolved by the mediation and arbitration provisions of Appendix A.

5.2

Toshiba Indemnity. Toshiba shall indemnify SanDisk and its Indemnified Parties from any environmental costs, expenses or liabilities of SanDisk resulting from, arising out of or otherwise by virtue of:

(a)

environmental conditions existing at the Yokkaichi Facility (including the Y5 Facility or Other Y5 Facilities but excluding conditions from operations of the Y3 Facility and Y4 Facility) prior to the Closing;

(b)

the actions or omissions of Toshiba, its Affiliates or its or their respective employees, directors, agents or representatives (other than in connection with the operation of the Y5 Facility or Other Y5 Facilities), for which Toshiba shall be solely responsible; provided however, that Toshiba shall have no indemnification obligation under this Section 1425.2(b) to the extent that any Environmental Costs result from, arise out of or otherwise occur by virtue of actions or omissions of SanDisk, its Affiliates or its or their respective employees, directors, agents or representatives, for which SanDisk shall be solely responsible; or

(c)

from the operations of the Y5 Facility or Other Y5 Facilities after the FF Termination Date (unless SanDisk is the Buyer for purposes of Section 1425.3, in which case this Section 1425.2(c) shall not apply).

5.3

Buyer Indemnity. If either of Toshiba or SanDisk (as "Buyer") acquires the interests of the other (as "Seller") in the Company, the Y5 Facility and Other Y5 Facilities (whether through acquiring its FF Interests, by an asset sale and liquidation or by other means), then, subject to Section 1427, Buyer shall indemnify Seller and its Indemnified Parties from any environmental costs, expenses or liability of Seller resulting from, arising out of or otherwise by virtue of, operations of the Y5 Facility and Other Y5 Facilities after the FF Termination Date. However, Buyer shall have no indemnification obligation under this Section 1425.3 to the extent that any Seller environmental costs, expenses or liabilities result from, arise out of or otherwise by virtue of actions or omissions of Seller, its Affiliates or its or their respective employees, directors, agents or representatives.

4


5.4

Control by Indemnifying Party.

(a)

The indemnifying Party under Section 1425.2 or 1425.3 shall have the sole right to control the defense of any claim and the method and scope of remediation with respect to which the indemnified Party seeks indemnification, provided that the indemnifying Party shall not enter into any settlement that would materially affect the operations of the indemnified Party at the Yokkaichi Facility unless the indemnified Party has granted its prior written consent.

(b)

The Parties shall cooperate in good faith to seek to agree upon the means of joint defense of any third party claim giving rise to Covered Environmental Costs (with any disagreement to be resolved by the mediation and arbitration provisions set forth in Appendix A).

5.5

Liability Limit. Neither Party153s aggregate liability for Covered Environmental Costs or indemnification obligations under Sections 1425.1, 1425.2 and 1425.3 shall exceed the greater of (a) US$5 million or (b) the aggregate (i) purchase price of the products purchased by such Party from Flash Forward and (ii) transfer price of the products produced for such Party at the Y5 Facility (which for purposes of computing this aggregate shall be deemed to be no less than cost plus one percent (1%)), during the six years prior to the date of the applicable claim (or in the case of liability arising after the FF Termination Date, for the six year period immediately preceding the FF Terminate Date).

6.

Satisfaction of Indemnification Obligations.

6.1

Prompt Payment. Each Party shall promptly pay its Share of any Covered Environmental Costs paid by the Company or by the other Party in excess of its obligation to bear the Covered Environmental Costs. In the event that any Covered Environmental Costs are incurred by the Company or disproportionately by a Party in excess of its Share, the Company or such Party, as applicable, shall invoice the other Party or Parties directly for the balance of such Covered Environmental Costs to the extent of such Party153s Share in accordance with Section 1425.1(a); provided, however, that upon the mutual agreement of the Parties, each Party153s respective Share of Covered Environmental Costs may otherwise be paid via adjustments to the purchase prices they pay to the Company for Y5 NAND Flash Memory Products, pursuant to the applicable Master Operative Documents. The Parties shall discuss in good faith the means and the timing of payment of their respective Shares of Covered Environmental Costs, taking into account when the Covered Environmental Costs are paid by the Company or by the other Party and the amount of such Covered Environmental Costs. To the extent the obligations of either Party will not be timely or fully retired by wafer price increases, the Parties shall directly pay their respective Shares of Covered Environmental Costs.

6.2

Action in the Name of the Company. Either Party making a demand for indemnification or contribution pursuant to this Agreement shall be entitled, notwithstanding anything to the contrary in the FF Master Agreement or the FF Operating Agreement, to cause the Company to make such demand, if doing so is appropriate to fulfill the intent of this Section 1426 (e.g., if the Company has borne the Covered Environmental Costs and the claiming Party has already reimbursed the Company for its Share of the same).

7.

Post Termination Environmental Costs and Exit Environmental Report.

7.1

Environmental Costs Paid Post Termination. Except as otherwise set forth in this Section 1427, the Parties153 obligations under Section 1425.1 shall expire as of the FF Termination Date.

(a)

In respect of Environmental Costs for remediation, to the extent the Exit Environmental Report (as defined below) identifies contamination at the Y5 Facility or Other Y5 Facilities and a good faith claim concerning shared responsibility for such remediation costs is made by one of the Parties before the FF Termination Date, any obligations of the Parties under Section 1425.1(a) (subject to Section 1425.1(b)) in respect of remediation of such contamination shall survive the FF Termination Date, but only for so long and to the extent the Prudent Operator Standard continues to require remediation in respect of such contamination.

(b)

In respect of Covered Environmental Costs resulting from a bona fide third party claim, the Parties obligations under Section 1425.1(a) (subject to Section 1425.1(b)) shall survive ****.

5


7.2

Exit Environmental Report.

(a)

Promptly upon (i) the exercise by either Party of any right under the FF Operating Agreement and/or the FF Master Agreement to acquire the FF Interests of the other Party, to sell its FF Interests to the other Party or to cause the dissolution of the Company, or (ii) entering into any letter of intent or agreement for the sale of the Y5 Facility and Other Y5 Facilities or all or substantially all of the assets (leased or owned) of the Company, the Parties shall engage an environmental consultant from an internationally recognized environmental investigation firm that has experience in Japan and that is mutually acceptable to the Parties (the "Exit Consultant") to conduct and complete Phase I and Phase II investigations of the Y5 Facility and Other Y5 Facilities as of a date as close as practicable to but in any event in advance of the FF Termination Date. Toshiba shall facilitate the Exit Consultant153s access to the Yokkaichi Facility as reasonably necessary to conduct such investigations.

(b)

The Exit Consultant shall be directed to prepare a draft report based on its Phase I and Phase II investigations and to deliver the draft report to SanDisk and Toshiba (and if either so directs, to any environmental consultant either Party has engaged for its own account). SanDisk and Toshiba, directly and/or through their respective consultants, shall have sixty (60) days from receipt to comment on the draft report (any such comment shall be delivered both to the Exit Consultant and the other Party and any consultant it engages for its own account). The Exit Consultant shall then be directed to issue to the Parties its final report (the "Exit Environmental Report"), which shall be final and binding on the Parties.

(c)

Environmental Costs arising from the Exit Environmental Report process shall be payable as provided in Article 1425 and Section 1426.1.

(d)

Unless all payments due for Covered Environmental Costs in connection with the Exit Environmental Report process have been made before the FF Termination Date, the Buyer shall be entitled to withhold from the purchase price payable (or distributable) to Seller and place into third party escrow up to **** of such purchase price (but not to exceed the balance of Seller153s liability limit in Section 1425.5), which shall serve as security for Seller153s responsibility for Covered Environmental Costs determined pursuant to this Section 1427.
