No provision of this Agreement may be amended, modified or waived in whole or in part at any time without the express written consent of the Company and the Shareholders holding in aggregate more than fifty percent (50%) of the Company Shares held by the Shareholders; provided that any such amendment, modification or waiver that (i) would be materially adverse in any respect to any Qualifying Shareholder shall require the prior written consent of such Qualifying Shareholder or (ii) would be disproportionately adverse to any Sponsor relative to the Qualifying Shareholders (or, to the extent there are no Qualifying Shareholders, relative to the other Sponsors) shall require the prior written consent of such disproportionately adversely affected Sponsor.
