If for any reason the Program is not capable of being executed as planned, or if there is an infection by computer virus, bugs, tampering, unauthorized intervention, fraud or technical failures, or if any other causes beyond the control of Administrators corrupt or affect the administration, security, fairness, integrity, or proper conduct of this Program, the Administrators reserve the right, in their sole discretion, to withdraw the transmission of any vote. Furthermore, the Administrators may permanently disqualify from any promotion any person they believe has intentionally violated these rules, and to terminate or suspend voting at any point and declare the vote results based on the votes up to that point, if it appears that the voting process has been so distorted by hacking or other interference that the results would not reflect actual valid votes should the voting continue. In the event of technical difficulties with the online voting, Administrators reserve the right to review the votes for accuracy and to take any appropriate action, including, without limitation, voiding the votes cast during the Voting Period in which such technical difficulties occurred. Administrators and their respective agents, officers, directors, employees, subsidiaries and affiliates assume no responsibility for any injury or damage to participants or to any other person's computer relating to or resulting from entering or downloading materials or software in connection with this Program.

These Terms and Conditions are subject to change at any time at the sole discretion of the Administrators. Notification regarding any such change will be posted at www.cbs.com/bigbrother.

Caution: Any attempt by an individual to deliberately damage any online service or website, tamper with the voting process, or otherwise undermine the legitimate operation of the Program is a violation of criminal and civil laws and should such an attempt be made, Administrators reserve the right to seek damages and/or other remedies from any such person to the fullest extent permitted by law.
