ARTICLE II

GRANT OF LICENSE; ACKNOWLEDGEMENTS; RELEASE

2.1 Subject to the terms and conditions of this Agreement, Overture hereby grants to Licensee and its subsidiaries a worldwide non-exclusive, non-transferable, non-assignable, and non-sublicensable
limited license under the Licensed Patents to allow Licensee to use the Licensed Patents, to the extent applicable, in connection with Licensees operation of the Licensee System. Any entities or businesses acquired by Licensee after the
Effective Date shall be included hereunder only as of such date of acquisition, and this Agreement shall not apply to release any such after-acquired businesses or entities from potential claims based upon or arising out of the Licensed Patents
before such date of acquisition. No other license, express or implied, is granted to Licensee under any other patent, patent application, or other proprietary right of Overture.

2.2 Licensees acceptance of this grant of license is not an admission of use, performance or exploitation of the Licensed Patents
in connection with the businesses of Licensee and its wholly-owned subsidiaries prior to the Effective Date, nor an obligation to use, perform or otherwise exploit the Licensed Patents in connection with its Licensee System or other businesses
during the Term hereof. Licensee shall not be restricted in any manner from licensing, developing or otherwise acquiring intellectual property that may substitute or be used in conjunction with the Licensed Patents to the extent applicable.

2.3 Except as to executory performances required under this Agreement, Overture hereby
unconditionally assigns, releases and absolutely and forever discharges Licensee and its wholly-owned subsidiaries at the date of this Agreement, and each of their past, present, and future officers, directors, employees, agents and representatives,
and predecessors, and each of them, from any and all claims, demands, damages, debts, losses, causes of action, costs, expenses, accounts, obligations, attorneys fees, liabilities, actions, causes of actions and indemnities of all and any
nature whatsoever, under the law of any jurisdiction worldwide, whether known or unknown, suspected or unsuspected, whether concealed or hidden, which Overture now has, owns or holds or at any time heretofore ever had, owned or held, or could, shall
or may hereafter have, own or hold against Licensee and its wholly-owned subsidiaries, based upon or arising out of the Licensed Patents prior to the Effective Date (collectively referred to as the Released Matters). It is the intention
of the parties in executing this Agreement that this Agreement shall be effective as a full and final accord and satisfaction and general release of and from the Released Matters. With respect to any and all of the claims encompassed by this
Section, Overture intends to and does hereby expressly waive, to the fullest extent permitted by law, the provisions, rights, and benefits of Section 1542 of the California Civil Code, which provides that:

A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the
release, which if known by him must have a materially affected his settlement with the debtor.

Overture further agrees that it may hereafter
discover facts in addition to or different from those which are known or believed by Overture to be true with respect to the subject matter of this Section, but Overture nonetheless intends to, and does hereby fully, finally, and forever release any
and all such claims, as described above, without regard to the subsequent discovery or existence of such different or additional facts.

ARTICLE III
