Notices shall be
deemed given upon personal delivery, five (5) days after deposit in the mail, confirmation of facsimile or upon acknowledgment of receipt, or, if delivery is not accomplished by reason of some fault of the addressee, when tendered for delivery.
Either party may give written notice of a change of address and, after notice of such change has been received, any notice or request shall thereafter be given to such party as above provided at such changed address.



7.6 Assignment. This Agreement shall terminate in its entirety in the
event that either party undergoes a Change of Conrol (as Change of Control is defined in the Patent License Agreement, but without regard to whether or not to the Third Party involved in the respective transaction is an Electronics
Company as defined in the Patent License Agreement); provided, however, that Broadcom will not unreasonably withhold consent for a successor-in-interest of Microtune in such transaction to use the units of the Reference Design Product as
described in Section 2.3. Neither party may assign this Agreement or any right or obligation under this Agreement without the prior written consent of the other party. Subject to the foregoing, this

Agreement shall be binding upon and inure to the benefit of the parties and their permitted successors and assigns.



7.7 Governing Law. This Agreement and matters connected with the
performance thereof shall be construed, interpreted, applied and governed in all respects in accordance with the laws of the United States of America and the State of New York, without reference to conflict of laws principles.



7.8 Jurisdiction; Waiver. Microtune and Broadcom agree (i) that all
disputes and litigation regarding this Agreement and matters connected with its performance be subject to the exclusive jurisdiction of the federal courts located in Houston, Texas, and (ii) to submit any disputes, matters of interpretation, or
enforcement actions arising with respect to the subject matter of this Agreement exclusively to these courts. The parties hereby waive any challenge to the jurisdiction or venue of these courts over these matters.



7.9 Severability. If any provision of this Agreement is held to be
illegal or unenforceable, such provision shall be limited or eliminated to the minimum extent necessary so that the remainder of this Agreement will continue in full force and effect and be enforceable. The parties agree to negotiate in good faith
an enforceable substitute provision for any invalid or unenforceable provision that most nearly achieves the intent of such provision.



7.10 Entire Agreement. This Agreement, together with the Settlement Agreement and the Patent License Agreement, embodies the entire understanding
of the parties with respect to the subject matter hereof and thereof, and merges all prior discussions between them, and neither of the parties shall be bound by any conditions, definitions, warranties, understandings, or representations with
respect to the subject matter hereof other than as expressly provided herein. No oral explanation or oral information by either party hereto shall alter the meaning or interpretation of this Agreement. This Agreement, the Patent License Agreement
and the Business Agreement are independent agreements that shall be governed and construed according to their own terms and a breach or default under any one such agreement shall not be considered a breach or default under any of the other
agreements.



7.11 Modification; Waiver. No modification
or amendment to this Agreement, nor any waiver of any rights, will be effective unless assented to in writing by the party to be charged, and the waiver of any breach or default will not constitute a waiver of any other right hereunder or any
subsequent breach or default.



7.12 No Third Party
Beneficiaries. This Agreement is solely for the benefit of the Microtune and Broadcom. No other Person shall be entitled to rely on this Agreement or to anticipate the benefits of this Agreement or otherwise assert or be entitled to any rights
as a third party beneficiary hereof.



7.13 Construction.
Any rule of construction to the effect that ambiguities are to be resolved against the drafting party will not be applied in the construction or interpretation of this Agreement. As used in this Agreement, the words include and
including, and variations thereof, will not be deemed to be terms of limitation, but rather will be deemed to be followed by

the words without limitation. The headings in this Agreement will not be referred to in connection with the construction or interpretation of
this Agreement.



7.14 Counterparts. This Agreement may
be executed in counterparts or duplicate originals, both of which shall be regarded as one and the same instrument, and which shall be the official and governing version in the interpretation of this Agreement. This Agreement may be executed by
facsimile signatures and such signatures shall be deemed to bind each party as if they were original signatures.
