Closing in the case of Designated Employees (other than the Call Employees), or the Second Closing in the case of the Call Employees, (ii) be subject to and in compliance with Buyers standard human resources policies and procedures, including

Date and, accordingly, that Seller and the Selling Group shall be solely responsible for providing continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (COBRA) to those individuals who
are M&A qualified beneficiaries (as defined in Treasury Regulation Section 54.4980B-9, Q&A-4(a)) with respect to the transactions contemplated by this Agreement (collectively, the M&A Qualified Beneficiaries). Seller

liabilities and claims related to M&A Qualified Beneficiaries and all other qualified beneficiaries (as defined in Code Section 4980B(g)(1)) with respect to Sellers group health plans. Seller further agrees and acknowledges that in the
event that the Selling Group ceases to provide any group health plan to any employee prior to the expiration of the continuation coverage period for all M&A Qualified Beneficiaries (pursuant to Treasury Regulation Section 54.4980B-9,
Q&A-8(c)), then Seller shall provide Buyer with (a) written notice of such cessation as far in advance of such cessation as is reasonably practicable (and, in any event, at least thirty (30) days prior to such cessation), and (b) all information

ARTICLE 7

COVENANT NOT TO COMPETE OR SOLICIT



7.1 Covenant Not to Compete. Beginning on the First
Closing Date and ending on the thirty (30) month anniversary of the First Closing Date, neither Seller nor any of its Affiliates or permitted successors or assigns shall, directly or indirectly, without the prior written consent of Buyer, engage
anywhere in the world in (whether as an agent, consultant, advisor, independent contractor, proprietor, partner, officer, director or otherwise), in the design, manufacture, marketing or sale of Transferred Devices or similar products intended for
use in the Field, or otherwise engage in a business in the Field (the foregoing, the Restricted Activities);provided, however, that nothing in this Section 7.1 shall restrict Seller from acquiring ownership of an equity
interest not greater than fifteen percent (15%) in an entity engaged in the Restricted Activities, provided that during the four (4) consecutive calendar quarters prior to Sellers acquisition of such equity interest and at all times
thereafter, such entitys engagement in the Restricted Activities contributed not more than twenty-five percent (25%) of the total sales of such entity.



Notwithstanding the foregoing provisions of this Section 7.1, during the period beginning on the First Closing Date and ending on the Second Closing Date
(or if such Second Closing does not occur, then perpetually thereafter), Seller and its Affiliates may engage in the foregoing activities in accordance with Section 6.3(b) solely with respect to the Call Assets. Notwithstanding the forgoing, nothing
herein shall restrict Sellers or its Affiliates engaging in business activities outside of the Field or Seller or its Affiliates engaging in business activities with respect to: (i) discrete components, (ii) physical-layer devices,
(iii) memory and (iv) ASICs where the intellectual property contained in the Field definition of this Agreement is substantially supplied by customer.

neither Seller or its Affiliates nor Buyer or its Affiliates shall, directly or indirectly, without the prior written consent of the other Party, solicit to
employ any of the employees of the other Party who perform services for such Party in connection with such Partys engagement in the Business or encourage any such employee of the other Party to terminate his or her employment with the other
Party. For purposes of the preceding sentence, the terms solicit and encourage shall not include the following activities: (a) advertising for employment in any bulletin board (including electronic bulletin boards),
newspaper, trade journal or other publication available for general distribution to the public without specific reference to any particular employees, (b) participation by a Party in any hiring fair or similar event open to the public not targeted
at the other Partys employees, and (c) use of recruiting or employee search firms that are not targeting employees of the other Party.



7.3 Severability of Covenants. The covenants contained in the preceding paragraphs shall be construed as a series of separate
covenants, one for each county, city and state of any geographic area where any business is carried on by Buyer. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in the
preceding paragraphs. If, in any judicial proceeding, a court refuses to enforce any of such separate covenants (or any part thereof), then such unenforceable covenant (or such part) shall be eliminated from this Agreement to the extent necessary to
permit the remaining separate covenants (or portions thereof) to be enforced. If the provisions of this Article 7 are deemed to exceed the time, geographic or scope limitations permitted by applicable law, then such provisions shall be reformed to
the maximum time, geographic or scope limitations, as the case may be, permitted by applicable laws.

breach of the covenants set forth in this Article 7. Accordingly, Seller agrees that if it breaches any provision of this Article 7, Buyer will have available, in addition to any other right or remedy otherwise available, the right to seek an
injunction from a court of competent jurisdiction restraining such breach or threatened breach and to specific performance of any such provision of this Agreement without the requirement that Buyer post a bond.

(a) Whenever any Loss shall be asserted against or incurred by a Buyer Indemnitee or Seller Indemnitee (the Indemnified Party), the Indemnified Party shall give written notice thereof (a
Claim) to Seller or Buyer, respectively (the Indemnifying Party). The Indemnified Party shall furnish to the Indemnifying Party in reasonable detail such information as the Indemnified Party may have with
respect to the Claim (including in any case copies of any summons, complaint or other pleading which may have been served on it and any written claim, demand, invoice, billing or other document evidencing or asserting the same). The failure to give
such notice shall not relieve the Indemnifying Party of its indemnification obligations under this Agreement except to the extent that such failure actually prejudices the Indemnifying Party.



(b) If the Claim is based on a claim of a person that is not
a party to this Agreement, the Indemnifying Party shall, at its expense, undertake the defense of such Claim with attorneys of its own choosing reasonably satisfactory to the Indemnified Party. In the event the Indemnifying Party, within a
reasonable time after receiving notice of a Claim from the Indemnified Party, fails to defend the Claim, the Indemnified Party may, at the Indemnifying Partys expense, undertake the defense of the Claim and may compromise or settle the Claim,
all for the account of the Indemnifying Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such Claim, the Indemnifying Party shall not be liable to the Indemnified Party under this
Section 12.4 for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof, except for such expenses incurred in connection with cooperation with, or at the request of, the Indemnifying Party;
provided, however, that the Indemnified Party shall have the right to engage counsel to represent it if, in the Indemnified Partys reasonable judgment, based upon the advice of counsel, it is advisable, in light of the separate
interests of the Indemnified Party and the Indemnifying Party, for the Indemnified Party to be represented by separate counsel, and in that event the reasonable fees and expenses of such separate counsel shall be paid by the Indemnifying Party.



(c) The Indemnifying Party shall not consent
to entry of any judgment, except with the consent of the Indemnified Party given in its sole discretion, or enter into any settlement, except with the consent of the Indemnified Party, which such consent shall not be unreasonably withheld or
delayed. In the event the Indemnified Party refuses to consent to the entry of a judgment or a settlement for which the Indemnifying Party is solely and entirely responsible and has indicated its sole and entire responsibility in writing to the
Indemnified Party, following such refusal, the liability of the Indemnifying Party to the Indemnified Party will be fixed at the amount of any money damages provided in the proposed judgment or settlement.

Sellers total liability under this Section 12.5 will not exceed Two Hundred Fifty Thousand United States dollars (US$250,000.00). Notwithstanding the forgoing, Seller shall only be obligated to make payments under this Section 12.5 to the
extent Buyer incurs Losses by doing a metal mask change, full mask set change or new redesign of the Daffodil Integrated Circuit.

14.14 Waiver. No failure on the part of a Party to exercise any power, right, privilege, or remedy under this Agreement, and no delay on the part of any Party in exercising any power, right, privilege, or remedy under this Agreement,
will operate as a waiver of such power, right, privilege, or remedy; and no single or partial exercise of any such power, right, privilege, or remedy will preclude any other or further exercise thereof or of any other power, right, privilege, or
remedy. No Party shall be deemed to have waived any claim arising from this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a
written instrument duly executed and delivered on behalf of such Party; and any such waiver will not be applicable or have any effect except in the specific instance in which it is given.



14.15 License Rights in Bankruptcy. All rights and
licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n)



-55-



---

of the United States Bankruptcy Code, licenses to rights of Intellectual Property Rights as defined thereunder. Notwithstanding any provision
contained herein to the contrary, if a licensor hereunder is under any proceeding under the Bankruptcy Code and the trustee in bankruptcy of such licensor, or such licensor, as a debtor in possession, rightfully elects to reject the licenses granted
to the licensee under this Agreement, the licensee may, pursuant to 11 U.S.C. Section 365(n)(1) and (2), retain any and all of the licensees rights under such licenses, to the maximum extent permitted by law, otherwise subject to the terms of
this Agreement.



14.16 Assignment.
Prior to the earlier of the Second Closing Date or the Call Expiration Date, neither Party may assign this Agreement in whole or in part without the prior written consent of the other Party, except for an assignment in whole to an Affiliate or an
assignment in whole in connection with a Change of Control provided that such assignee agrees in writing to be bound by this Agreement and to ensure that such assignees Affiliates comply with the terms hereof. After such date, except as
provided herein, Buyer may assign or transfer this Agreement in whole or in part. After such date, except as provided herein, Seller may assign or transfer this Agreement to an Affiliate or to its successor in a Change of Control provided that such
assignee agrees in writing to be bound by this Agreement and to ensure that such assignees Affiliates comply with the terms hereof. Nothing set forth in this Section 14.16 shall permit either Party to assign or transfer any right or license
set forth in this Agreement which by its terms is not assignable. Any assignment of rights or licenses in conjunction with an assignment of this Agreement in its entirety pursuant to this Section 14.16 shall be subject to all terms or conditions
hereunder that would apply had such rights or licenses been assigned or transferred separately. The assignment or transfer by Seller to a third party of any Intellectual Property Rights licensed or to be licensed to Buyer hereunder shall be subject
to, and not limit, such licenses to Buyer. Any attempt to transfer or assign except as provided herein shall be void and of no effect. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the successors or
permitted assigns of the Parties. Nothing set forth herein shall in any way limit the transfer, assignment or licensing by Buyer of the Transferred Assets in their entirety or in part after the First Closing.



14.17 Severability. If, for any reason, a court of
competent jurisdiction finds any provision of this Agreement, or portion thereof, to be invalid or unenforceable, such provision of the Agreement will be enforced to the maximum extent permissible so as to effect the intent of the Parties, and the
remainder of this Agreement will continue in full force and effect. The Parties agree to negotiate in good faith an enforceable substitute provision for any unenforceable provision that most nearly achieves the intent and economic effect of the
unenforceable provision. Notwithstanding the foregoing, if a court of competent jurisdiction determines that any restriction on any license granted herein is invalid or unenforceable, then the license grants to which such restriction relates shall
terminate automatically.



14.18 Entire
Agreement. This Agreement (including the Collateral Agreements, Schedules and Exhibits hereto) sets forth the entire understanding of the Parties hereto relating to the subject matter hereof and supersedes all prior agreements and understandings
between the Parties hereto relating to the subject matter hereof including the letter agreement entered into between the Parties dated January 28, 2005.

14.19 Amendments. This Agreement may not be amended, modified, altered or
supplemented other than by means of a written instrument duly executed and delivered on behalf of Seller and Buyer.
