Rights of HUD if Agency defaults under ACC. The ACC will provide that, if the Agency fails to comply with any of its obligations, HUD may determine that there is a substantial default and require the Agency to assign to HUD all of its rights and interests under the Contract; however, HUD will continue to pay annual contributions in accord- ance with the terms of the ACC and the Contract. Before determining that an Agency is in substantial default, HUD will give the Agency a reasonable op- portunity to take corrective action.
