1.11 In order to expeditiously compromise all issues concerning the reasonableness of outstanding fee bills, St. Paul agrees to reimburse Defense Costs to Microtune on the following basis:



(a) Through June 22, 2004, Microtune submitted to St. Paul
for reimbursement under its Policy invoices reflecting Defense Costs in the Securities Class Action of $2,419,091 (a portion of which included a fifty percent (50%) share of Defense Costs relating to the SEC document production), and Defense Costs
in the Derivative Litigation of $125,310, for a total of $2,544,401;



(b) Subsequent to that date, additional Defense Cost invoices were forwarded by Microtune but have not been reviewed or evaluated by St. Paul or other D&O Carriers. Additionally, it was reported by Microtune at
the mediation that an additional $205,861 was incurred, but not billed, for Defense Costs in the Securities Litigation through the date of the mediation; and $5,200 was incurred, but not billed, in the Derivative Litigation;

(d) To compromise and settle the disputes
concerning reimbursement of Defense Costs, the D&O Carriers and Microtune agree that [***] of the Defense Costs comprising the $[***] total described above - or $[***]  shall be reimbursed under the terms of the D&O Policies

1.12 Microtune and
Sheffield agree that Sheffield will pay all additional Defense Costs making up the difference between the amount paid by St. Paul pursuant to Paragraph 1.11 (including its subsections) above and the total amount owed under the Sheffield Policy
towards the Reimbursed Fee Amount ($[***]) and will continue to reimburse Microtune for Defense Costs incurred in connection with the Securities Class Action and the Derivative Litigation on the same basis that St. Paul is reimbursing Microtune for
the fee statements submitted prior to the mediation, such that:

3.2 The Microtune Parties acknowledge that (1) they may have sustained damages, expenses and losses in connection with the subject matter of the Claims released hereunder (the Released Claims) which are
presently unknown or not suspected and that such damages, expenses, and losses, if any, may give rise to additional damages, expenses and losses in the future which are not now anticipated by them; and (2) that this Agreement and the foregoing

4. CONFIDENTIALITY



4.1 The Parties understand and agree that the negotiations leading to, and the terms of, this Agreement are confidential and further agree not to disclose

requested or required (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or
other process), by a non-signatory to disclose the terms of this Agreement, except for a request from a Partys auditor or attorneys, the Disclosing Party will provide the other Parties with written notice of any such request or requirement as
soon as reasonably practicable, setting forth verbatim all information that it proposes to disclose, the identity of each person or entity to whom the information is to be disclosed, the confidentiality agreement governing such disclosure, and the
circumstances pursuant to which the disclosure is proposed to be made, so that any other Parties may (i) seek an appropriate protective order at its sole expense; (ii) seek the Disclosing Partys cooperation to narrow the request or demand,
which cooperation shall not be unreasonably withheld; and/or (iii) waive compliance with the provisions of this Agreement.



4.3 If, failing the entry of a protective order or the receipt of a waiver hereunder, such Disclosing Party is, in the opinion of its counsel, compelled
to disclose the terms of this Agreement, the Disclosing Party may disclose only that portion of the terms of this Agreement that the Disclosing Party is compelled to disclose, and the Disclosing Party will exercise reasonable efforts to obtain
assurance that confidential treatment will be accorded any disclosed terms of this Agreement. In any event, the Disclosing Party will not oppose action by any other Party to obtain an appropriate protective order or other reliable assurance that
confidential treatment will be accorded to the terms of this Agreement.
