(a) Protect and enhance the integrity of elections;

(b) Create a record of all versions, including changes or modifications of the source code materials placed in escrow;

(c) Create a record of all applications for access to the source code materials placed in escrow; and

(d) Unless otherwise superseded by a contract between a vendor and an election jurisdiction, preserve the necessary source code information to permit the election jurisdiction to continue the use and maintenance of the source code in the event the vendor is unable, or otherwise fails, to provide maintenance. At no time shall this be construed as a way for either the vendor or the county to violate a contractual obligation to gain access to source code.
