The CIBC Agreement contains customary affirmative and negative covenants, including, among other requirements, financial statement reporting requirements, limitations on the incurrence of certain indebtedness and liens, limitations on the disposition of assets, restrictions on certain transactions with affiliates, limitations on dividends and stock repurchases and a material adverse change event of default.
