There's a lot of back and forth about the Arco loan being forgiven. Here's the applicable language from the Arco loan:

I do not read this as an automatic loan forgiveness if a new arena is built. Under one reading, Sacramento could build an arena that's simply not capable of "being the home venue of a major league sports franchise" such as a pure concert venue with no locker rooms or practice facilities. This might be risky because there are many versions of major league franchises and each league might require less facilities. For a strange example, it might be the case that one league or franchise does not require locker rooms for its home venue, in which case the loan would be forgiven. Nevertheless, it's worth looking into because a pure concert hall would serve the purpose to bleed out the Maloofs from Arco's musical functions and perhaps force them to sell the Kings due to lack of Arco profits.
If that's the wrong reading, there are other ways to read it as well such as: The Maloof's would have the loan forgiven if they are not the prime user of a city arena that they agreed to use. That part is bad. But there's also the second clause which could make the sentence read like there is a second issue: The Maloof's would have the loan forgiven if they are not the prime user of a city arena that another major league franchise has a better deal offered to it than to the Maloofs. In this instance, the city could build an arena and simply offer the Maloofs a same or better deal than any other sports franchise that may use the arena and the Arco loan would not be forgiven. The Maloofs would not even have to accept the city's deal. They could reject the terms, still play in Arco, but the loan would not be forgiven because they were offered the same or better deal as another franchise.
