Exhibit C

Bi-Lateral Confidentiality and Non-Disclosure Agreement

This Bi-Lateral Confidentiality and Non-Disclosure Agreement is entered into and effective on December 16, 2002 by and between Mellanox Technologies, Ltd. having a principal place of business at XX Xxx 000, Xxxxxxx, Xxxxxx 00000 (“Customer”) and Vitesse Semiconductor Corporation, a Delaware, U.S.A. corporation with a principal place of business at 000 Xxxxx Xxxxx, Xxxxxxxxx, Xxxxxxxxxx 00000.

Either or both Vitesse and Mellanox have disclosed or will disclose to the other certain confidential and proprietary information (“Information”) further described as: the Technology and Intellectual Property described in Exhibit B of this agreement.

The parties desire that Information exchanged be used solely for the purpose of conducting business with each other and desire to set forth their agreement regarding the limited use and preservation of confidentiality of such Information. Each of the parties acknowledges that the other party’s Information is a valuable, special, and unique asset of such party. Each party therefore agrees, for itself and on behalf of its officers, directors, agents, employees and affiliates, to use reasonable care to keep all such Information in confidence, to use Information solely for conducting business with the other, and not to disclose any portion of the Information to any third party without the prior written consent of the disclosing party.

In order to ensure that the Information disclosed by one party to the other is used only in accordance with the purposes stated above, the parties agree to the following:

1.		Information that is easily markable, whether in hard copy or electronic form, that the disclosing party in good faith regards as confidential and/or proprietary will be clearly marked as “Confidential”, “Proprietary”, or with other words indicating the sensitive nature of the Information. Any information orally disclosed by one party to the other will be deemed Information hereunder if, within thirty (30) days after the disclosure, the disclosing party so identifies it in writing to the other. Neither party will disclose to third parties or fail to treat as Information any information received orally from the disclosing party unless the disclosing party fails for thirty (30) days after such disclosure to identify the Information disclosed as being confidential or proprietary.
2.		Information otherwise protected hereunder will not include Information that the receiving party can demonstrate: (i) is now in or hereafter enters the public domain without any violation of this Agreement; (ii) was known to the receiving party prior to the time of disclosure by the disclosing party; or (iii) was disclosed in good faith to the receiving party by a third party legally entitled to disclose the same; provided, however, that specific Information will not be deemed to be within any of the foregoing exceptions merely because it is in the scope of more general Information.
3.		If the receiving party is confronted with legal action to disclose Information, the receiving party will promptly notify the disclosing party. The receiving party will reasonably assist the disclosing party in obtaining a protective order requiring that any portion of the Information required to be disclosed be used only for the purpose for which a court issues an order or for such other purposes as required by law. Each party will bear its own legal expenses.
4.		All Information will remain the property of the disclosing party. At the disclosing party’s written request, the Information in any tangible form will be promptly returned or destroyed together with all copies thereof. Upon written request, the receiving party will provide written certification of the destruction.
5.		The parties each acknowledge that should this Agreement be breached, remedies available at law are inadequate, and proving damages impracticable. The parties therefore agree that, in addition to all other rights and remedies available at law or in equity, the aggrieved party will be entitled to injunctive relief upon any such breach. The breaching party will pay to the aggrieved party all attorneys’ fees and costs incurred by the aggrieved party as a result of such breach.
6.		All notices required under this Agreement will be considered given if sent by certified mail, postage prepaid, and addressed as shown in Section 9.6 of the agreement (unless the addresses have been changed by written notice):
7.		The term of this Agreement is three (3) years from the effective date. The obligations under this Agreement will survive for five (5) years following termination of the parties’ association regardless of the manner of such termination, and will be binding upon their successors and assigns.
8.		This Agreement will be governed by, and interpreted in accordance with, the laws of the State of California.
9.		The receiving party will comply in all respects with U.S. Export and Re-Export laws and regulations applicable to any Information.

IN WITNESS WHEREOF, the parties have executed this Agreement in duplicate originals.
