In the event that, and if for any reason, any portion of this Agreement shall be held to be invalid or unenforceable, it is agreed that the remaining covenants and restrictions or portions thereof shall remain in full force and effect, and that if the validity or unenforceability is due to the unreasonableness of the time or geographical area covered by said covenants and restrictions, said covenants and restrictions of this Agreement shall nevertheless be effective for such period of time and for such area as may be determined to be reasonable by a court of competent jurisdiction.
