Written Unitholder Actions. Any action required or permitted to be taken at any Unitholder meeting may be taken without a meeting if the Unitholders holding a number of Units sufficient to approve the action pursuant to this Agreement consent to such action in writing. Reasonably prompt notice of the taking of any action taken without a meeting by less than unanimous written consent, together with a copy of the action taken, will be given to those Unitholders who have not consented in writing.
