          extent) that it is convertible or exchangeable into an Equity Security
          at a price below the then Fair Market Value of such Equity Security
          and (ii) in no event shall the Senior Preferred Units (as defined in

          Securities will also include equity of the Company (or a corporate
          successor to the Company or a Subsidiary of the Company) issued with

     from Executive pursuant to the related Dilution Repurchase Option free and
     clear of all liens, restrictions, charges and encumbrances (other than as
     contemplated by the Agreement and the other agreements referenced therein)
     and the same will not be subject to any adverse claims and (b) acknowledges
     and agrees that, of the Standard Carried Common Units being purchased from
     Executive pursuant to the related Dilution Repurchase Option, 13,508
     constitute Vested Carried Common Units under the terms of the Agreement.

17.  Except for the changes noted above, the Agreement shall remain in full

     and the same instrument.
