Leased-License Holders Only. For leased-license holders of any previous version of vBulletin software, up to and including version 3.8, the License terminates on the last day of your current leased-license agreement with Jelsoft. You may, however, purchase the Software prior to such end date, in which case the License will continue as specified in the first paragraph of this Section 4. Use of the Software after that end date without purchase makes the License void and you must immediately cease using the Software, and destroy all complete and partial copies of the Software.
