Franchisees existing as of the effective date of this article shall, in addition to all the obligations and duties prescribed by the terms of their existing franchises, be subject to the substantive and procedural requirements in this chapter, except as prohibited by applicable law. Nothing in this chapter is intended to invalidate a lawful, existing franchise or to waive any obligations imposed by such a franchise. Notwithstanding the foregoing, provisions of this article that expressly refer to a "franchise granted pursuant to this article" shall not apply to franchises initially granted prior to the effective date of this article.
