property or process right, or any other property right nor does the furnishing of Confidential Information constitute an inducement of any kind, or any representation, warranty, assurance, or guarantee with respect to the noninfringement of
trademarks, patents, copyrights, methodologies, intellectual property rights or processes, or any other property rights of third persons or of SYNTEL. You agree to promptly redeliver to SYNTEL, upon request, all Confidential Information on any
tangible media and that you will not retain any copies, extracts or other reproductions in whole or in part of such material. You further agree that breach of this confidentiality letter agreement could cause irreparable harm to SYNTEL and that

consented to in writing by SYNTEL. This confidentiality letter agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. No amendment hereof shall be effective unless contained in a

covenants to be performed by the other party or of any breach shall not be construed to be a waiver of any succeeding breach or of any other covenant. If any provision of this confidentiality letter agreement is declared invalid, such provision
shall be deemed severable from the remaining provisions of the confidentiality letter agreement, which shall remain in full force and effect. All rights and remedies provided for in this confidentiality letter agreement shall be cumulative and in
