Divestment Sublicense. Buyer Parent shall have a right to grant to Toshiba Corporation (“Toshiba”) a sublicense under the rights granted to Buyer Parent pursuant to Sections 3.1, 3.6 and 3.7, effective upon the closing of Toshiba’s purchase from Buyer Parent of assets relating to the 3.5” HDD business owned by Viviti Technologies Limited pursuant to the Purchase Agreement in connection with any commitment to, order by, regulation of, or other obligation to a regulatory body, competition authority or similar entity including the commitments under the Case No. Comp M.6203 Western Digital / Viviti Technologies Commitments to the European Commission (collectively, such assets purchased by Toshiba constituting the “Divested Business”), subject to the following conditions:

(a)

the sublicense granted to Toshiba under the rights granted to Buyer Parent pursuant to Sections 3.1, 3.6 and 3.7 will apply only with respect to developing, making, Having Made, using, importing, exporting, selling, leasing, offering to sell, distributing and otherwise disposing of 3.5” HDDs in the ordinary course of Toshiba’s 3.5” HDD business;

(b)

the sublicense granted to Toshiba under the rights granted to Buyer Parent pursuant to Sections 3.1, 3.6 and 3.7 will apply only to the operation of the Divested Business, and not to the operation of any businesses or assets (whether or not related to 3.5” HDDs) possessed by Toshiba prior to Toshiba’s acquisition of the Divested Business, or acquired or developed by Toshiba independently of Toshiba’s acquisition of the Divested Business; and

(c)

the sublicense granted to Toshiba will be pursuant to a written agreement, satisfactory in form to Hitachi, obligating Toshiba to observe all applicable terms and conditions of this Agreement with respect to rights granted to Toshiba, and containing confidentiality terms at least as protective of the HITACHI Licensed Trade Secrets, and HITACHI’s rights therein, as the terms of Section 3.8 of this Agreement, and further containing terms expressly designating Hitachi as an intended third party beneficiary and providing that Hitachi shall have the right to exercise the same rights and remedies against Toshiba with respect to the sublicense as HITACHI may exercise against Buyer Parent with respect to the applicable provisions of this Agreement. For the avoidance of doubt, the form set forth as Exhibit A is satisfactory to Hitachi as relates to the sublicense pursuant to this Section 3.11.

Notwithstanding anything to the contrary, HITACHI may enforce any rights or seek any remedies arising from any act or omission by Toshiba directly against Toshiba or Buyer Parent; provided, however, that HITACHI will not seek injunctive relief against Buyer Parent, or terminate any rights of Buyer Parent pursuant to this Agreement, due to a breach of the sublicense by Toshiba. If HITACHI is unable to enforce any rights or remedies against Toshiba because of Toshiba’s status as a sublicensee under the sublicense agreement (as opposed to a direct licensee of HITACHI), then, Buyer Parent and its Subsidiaries shall reasonably cooperate with HITACHI to enforce such rights or obtain remedies (including, to the extent necessary, Buyer Parent’s or its Subsidiaries’ joining as a party to any enforcement action or terminating rights granted to Toshiba pursuant to the sublicense agreement). Buyer Parent shall provide a copy of the executed sublicense agreement to HITACHI, and, with respect to those terms relating to the sublicense from HITACHI, shall (i) not amend the sublicense agreement without HITACHI’s prior consent, (ii) provide HITACHI with prompt notice of any breach of the sublicense agreement by Toshiba of which Buyer Parent becomes aware, and (iii) not waive any such breach of the sublicense agreement by Toshiba without HITACHI’s prior consent.

7.	BUSINESS ACQUISITION, TRANSFER, CHANGE OF CONTROL, ETC.

7.1

Assignment and Change of Control of Buyer Parent HDD Business. Buyer Parent may assign or transfer the rights, licenses, and covenants under Section 3.1 of this Agreement in connection with any sale or other transfer of (i) all or substantially all of Buyer Parent’s HDD business, (ii) all or substantially all of Buyer Parent’s HDD-related assets in a single transaction or a series of transactions, or (iii) any transaction under which Buyer Parent undergoes a change in control.

7.2

Assignment of Buyer Parent Non-HDD Business. In connection with any sale or other transfer of (a) all or substantially all of Buyer Parent’s RAID, External Drive, and/or SSD business, or (b) all or substantially all of Buyer Parent’s RAID-, External Drive-and/or SSD-related assets in a single transaction or a series of transactions, Buyer Parent may assign or transfer the rights, licenses and

covenants under Sections 3.2, 3.3, 3.4, 3.5 and/or 3.6 corresponding to the sold or transferred business, subject to the following limitations:

(a)

The rights, licenses, and covenants under Sections 3.2, 3.3, 3.4, 3.5 and/or 3.6 shall be assignable provided that: the acquiring third party (“Acquiring 3rd Party”) agrees to grant a royalty-free license to HITACHI and the HITACHI Sublicensed Subsidiaries under the Patents which would fall within the scope of Buyer Parent SSD Patents or Buyer Parent RAID Patents if the Acquiring 3rd Party were named in the place of Buyer Parent in Sections 1.4 and 1.5 hereunder, in each case for the applicable term set forth in Section 4.1;

(b)

The rights, licenses, and covenants under Sections 3.2, 3.3, 3.4, 3.5 and/or 3.6 shall not be extended to the business originally run by the Acquiring 3rd Party or any of its Subsidiaries. To the extent that such rights, licenses and covenants continue to extend to the acquired portion of the business, the extension shall be limited to a revenue of such business equal to no more than the revenue of the acquired business in the twelve (12) months preceding such sale or transfer plus twenty percent (20%); and shall also be limited, in each of the successive twelve-month periods following such transfer or sale, to a revenue equal to no more than the immediately preceding twelve-month period plus twenty percent (20%). To the extent that the business exceeds this cap, and the Acquiring 3rd Party desires to obtain further rights and licenses, the Acquiring 3rd Party and HITACHI shall discuss a mutually acceptable resolution; and,

(c)

In no event shall the rights, licenses, and covenants under Sections 3.2, 3.3, 3.4, 3.5 and/or 3.6 supersede or relieve any obligation by any party to pay on-going royalties under any existing patent license agreement with respect to business operations of the Acquiring 3rd Party.

(d)

The rights, licenses, and covenants under Sections 3.2, 3.3, 3.4, 3.5 and/or 3.6 may not be assigned or transferred by Buyer Parent to any Acquiring 3rd Party if such Acquiring 3rd Party or any of its Subsidiaries has made, in court or otherwise, a written allegation of patent infringement against HITACHI that existed prior to the completion of the assignment or transfer and has not been resolved prior to the completion of the assignment or transfer.

7.3

Impact of Change of Control of Buyer Parent or HGST on Sections 3.2, 3.3, 3.4, 3.5 and 3.6 Licenses. In the event that in a single transaction or in a series of transactions Buyer Parent is acquired by a third party, through a merger, stock sale, asset purchase, or otherwise, HITACHI may, at its option, terminate the rights, licenses, and covenants under Section 3.2, 3.3, 3.4, 3.5 or 3.6 of this Agreement (but not the license under Section 3.1), if and only if the Acquiring 3rd Party or any of its Subsidiaries is a competitor in the RAID business. Buyer Parent shall timely notify HITACHI in writing of the acquisition with the

information reasonably required for HITACHI to determine whether or not to terminate those rights, including the framework and schedule of the acquisition. HITACHI shall notify, in turn, Buyer Parent in writing of its election whether or not to terminate the license within ninety (90) days after receipt of the notice. In the event that HITACHI chooses to terminate the license pursuant to the terms of this provision, HITACHI and Buyer Parent shall have a good faith basis upon which to renegotiate the license. Notwithstanding the foregoing, the rights, licenses and covenants in Sections 3.1 and 3.8 shall not be terminated in any event.

7.4

Acquisition of Non-HDD Business by Buyer Parent. In the event that Buyer Parent directly or indirectly acquires a Non-HDD Business pursuant to a merger, asset or stock purchase, or otherwise in a single transaction or a series of transactions during the Term, HITACHI shall have an option not to extend the rights, licenses, releases, and covenants under Section 3 to such Non-HDD Business; provided, however, if HITACHI exercises the option, the Patents owned or controlled by the acquired Non-HDD Business shall not be included in the definitions of Buyer Parent SSD Patents or Buyer Parent RAID Patents. Buyer Parent shall notify HITACHI in writing of the acquisition with information of the acquired Non-HDD Business reasonably required for HITACHI to determine the exercise of the option. HITACHI shall notify, in turn, Buyer Parent in writing of its exercise of the option or not within ninety (90) days after HITACHI received such notice without delay.

7.5

Assignment of RAID Business By HITACHI. HITACHI may assign or transfer the rights, licenses and covenants under Section 2.2 in connection with any sale or other transfer of (i) all or substantially all of HITACHI’s RAID business or (ii) substantially all of HITACHI’s related RAID assets in a single transaction or a series of transactions.

7.6

Assignment of SSD Business By HITACHI. HITACHI may assign or transfer the rights, licenses and covenants under Section 2.1 in connection with any sale or other transfer of (i) all or substantially all of HITACHI’s SSD business or (ii) substantially all of HITACHI’s related SSD assets in a single transaction or a series of transactions during the Term.

7.7

Change of Control of HITACHI. In the event that in a single transaction or in a series of transactions HITACHI is acquired by a third party, through a merger, stock sale, asset purchase, or otherwise, this Agreement shall remain effective and shall not be terminated.

7.8

Notice of Assignment/Transfer. In the event of a valid assignment or transfer (i.e., one made pursuant to the terms of Section 7.1, 7.2, 7.5 or 7.6 above) by either Party of this Agreement, the transferring or assigning Party shall, within ninety (90) calendar days, provide the other Party notice, in writing, of such assignment or transfer and shall identify the person to whom it has made such assignment or transfer.

7.9

Effect of Assignment. Any license, covenants and/or any other rights assigned by either Party pursuant to any provision of this Section 7 shall be effective with respect to the assignee (and its business and operations) on a prospective basis only. Accordingly, no such assignment shall relieve, release or discharge any assignee from any liability for damages accruing prior to the effective date of the applicable assignment due to the infringement of any Patent licensed under this Agreement. Should either Party assign or otherwise transfer this Agreement or any of its respective Patents, such transfer shall not operate to terminate, impair or in any way modify the licenses and releases provided by the Parties herein, except as expressly provided for under the terms of this Agreement.

7.10

Assignment of Patents. From and after any assignment or transfer of a Patent by either Party or its Subsidiaries, the assignee shall be bound by the terms and conditions of this Agreement with respect to such Patents.

7.11

Sublicense. Neither party, nor their Subsidiaries, may sublicense any rights under this Agreement unless otherwise provided hereunder.

8.	MISCELLANEOUS

8.2

Severability.

8.10

Disclosure.
