Investigators say the agreement was struck with Santa Clara County undersheriff Rick Sung and sheriff's Captain James Jensen, who have been put on administrative leave.
Apple Inc's security chief on Monday was indicted on bribery charges as prosecutors alleged he promised a donation of 200 iPads to the Santa Clara County Sheriff's Office to secure four concealed-weapon permits for Apple employees.

Ed Swanson, Moyer's attorney, said his client is innocent.
A two-year investigation by the DA's office found that Undersheriff Sung held up issuing CCW licenses until Moyer and Chadha "gave something of value".
"Given the fact that Laurie Smith, ultimately, is the person who has to sign off whether someone receives a hide weapons permit, it would appear that she could be logically the next target", said defense attorney Jaime Leanos. Jensen, who was previously indicted, is also now charged with asking for or receiving a bribe by an executive officer for the scheme involving Moyer, Palo Alto online reported.
According to Swanson, Apple frequently donates devices. "There was no quid pro quo", Mr Swanson insisted.More news: New restrictions placed on time travel when the animal crosses: New boundaries
At the behest of Sung, Chadha reportedly promised box seat tickets worth $6,000 worth to a San Jose Sharks hockey game at the SAP Center on Valentine's Day a year ago, according to the indictment.
The officers allegedly withheld the permits until Mr Moyer agreed to the deal, but it never went ahead when they found out the district attorney was investigating, according to reports. In California, concealed weapon permits, known as CCW licenses, are issued by county sheriffs based on a finding of "good cause" to approve a resident's application.
If convicted, the defendants could receive prison time.
An insurance broker was also implicated, as he offered US$6,000 in luxury sports seats in exchange for weapons permits, which the district attorney's office said usually cost between US$200 and US$400.More news: Agudath Israel, Catholic Diocese, Win Supreme Court Appeal Against Gov. Cuomo
"Ultimately, this case is about a long, bitter, and very public dispute between the Santa Clara County Sheriff and the District Attorney, and Tom is collateral damage to that dispute".
