The excecutives spoke on condition of anonymity because they were not authorized to discuss the matter publicly.
Hawes, who played for Philadelphia and Cleveland last season and made $6.5 million, will receive the Clippers' full mid-level exception, which starts at $5.305 million per year.
There have been reports that Clippers Coach and President Doc Rivers had been trying to work a sign-and-trade deal with Cleveland for Hawes so he could use the mid-level exception to try to get free-agent small forward Paul Pierce.
Hawes has the ability to stretch the floor with his outside shooting. He shot 41.6% from three-point range last season, and averaged 13.2 points and 8.3 rebounds.
Hawes also has become a good free-throw shooter, making 78.3% and 77.7% the last two seasons, 70.3% over his seven-year career.
Like all free agents who have agreed to deals since the free-agency period opened July 1, Hawes can’t sign his contract until Thursday, when the NBA lifts is moratorium.
Yahoo Sports first reported the agreement between the Clippers and Hawes.
