2.4 No Other Rights or Obligations.

2.4.1 No rights or licenses are granted by any Party or its Affiliates under any patents or other intellectual property, or for any products, other than as expressly set forth in this Agreement. For clarity, nothing in this Agreement shall be construed to grant to Sony or its Affiliates the right to authorize any party, other than Sony and its Affiliates, to engage in any of the activities described in Section 2.1, except the right for purchasers of Licensed Products to use and resell the Licensed Products that are actually sold by Sony and its Affiliates and the right of Sony and its Affiliates to purchase Licensed Products directly from a third party, in all cases excluding Foundry Activities and other activities not within the scope of Sony’s rights under Section 2.1.

For clarity, Sony or its Affiliates shall have the rights and licenses under Licensed Patents filed after the date of an Acquisition only to the extent that, prior to the date of Acquisition, (i) the patent or patent application claims an invention that was invented by a NeoMagic or its Affiliates’ employee, (ii) the patent or patent application was otherwise subject to an obligation to be assigned to NeoMagic or its Affiliates, or (iii) the patent or patent application was controlled by NeoMagic or its Affiliates. The Licensed Patents also shall not include any patents or patent applications that are first owned by or licensed to NeoMagic, NeoMagic Israel, or their Affiliates after the fifth (5^th) anniversary of the Effective Date. The foregoing shall not be construed to terminate or limit the rights of Sony and its Affiliates under the Licensed Patents to the extent existing at any time within the period commencing from the Effective Date and until immediately

before such Acquisition. For purposes of the foregoing, acquisition of more than fifty percent (50%) of NeoMagic’s stock shall be considered as an Acquisition.

All other rights and obligations under this Agreement shall survive such expiration.

4.3 All rights granted under the licenses, covenants not to assert, releases, discharges and other rights granted under or pursuant to this Agreement by NeoMagic and its Affiliates to Sony and its Affiliates are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11, U.S. Code (the “Bankruptcy Code”), licenses and rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The Parties agree that Sony and its Affiliates shall retain and may fully exercise and enjoy all rights and elections available to them under the Bankruptcy Code and other applicable laws and regulations.

Notwithstanding the foregoing, the prohibition against the disclosure of information as provided in this Section shall not apply to information, the disclosure of which is required in connection with the enforcement of a Party’s rights under this Agreement, pursuant to judicial order, or pursuant to applicable law; provided that, if disclosure is so ordered or required, the disclosing Party will use its best efforts to timely advise the other Party hereto prior to any disclosure and afford such other Party an opportunity to seek a protective order or other appropriate relief. Subject to any order or other directive quashing, staying, or otherwise granting relief from the required disclosure, the disclosing Party may disclose the required information after taking reasonable steps to preserve the confidentiality of such information, including restricting access to the information under a protective order for confidential information then in effect in the proceeding, or, absent such protective order, taking reasonable steps to obtain such a protective order.
