Naming rights: University of California--Irvine

Been reading (thanks to Brian Leiter) about the University of California-Irvine's Donald Bren School of Law.  Among the interesting aspects of Bren's agreement with the school is this:

Signs on law school buildings must read "Donald Bren School of Law" and be at least twice the size of the building name. Bren's must be the largest and most prominently displayed name on the building, according to the agreement.

I take it that is enforced as a contract, rather than as an affirmative covenant.
