       (a)    "EQUITY EQUIVALENTS" means, at any time, without duplication with

              warrants, options, convertible debt or equity securities,

              exercisable for or convertible or exchangeable into, directly or
              indirectly, Equity Securities or securities convertible or
              exchangeable into Equity Securities, whether at the time of
              issuance or upon the passage of time or the occurrence of a future
              event; PROVIDED THAT, (i) any of the foregoing shall only be
              considered an Equity Equivalent to the extent (and only to the
              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 the LLC Agreement) be deemed Equity
              Equivalents hereunder

       (b)    "EQUITY SECURITIES" means all Class A Preferred Units, Class B
              Preferred Units, Common Units and other Units (as defined in the
              LLC Agreement) or other equity interests in the Company (including
              other classes or series thereof having different rights) that are
              purchased simultaneously with Common Units as a strip of
              securities as may be authorized for issuance by the Company from
              time to time. Equity Securities will also include equity of the
              Company (or a corporate successor to the Company or a Subsidiary
              of the Company) issued with respect to Equity Securities (i) by
              way of a unit split, unit dividend, conversion, or other
              recapitalization, (ii) by way of reorganization or
              recapitalization of the Company in connection with the
              incorporation of a corporate successor in accordance with Section
              15.7 of the LLC Agreement, or (iii) by way of a distribution of
              securities of a Subsidiary of the Company to the members of the
              Company following or with respect to a Subsidiary Public Offering.

16.    In connection with the Follow-on Purchaser Equity Investment consummated
       as part of the Acquisition, Executive represents and warrants that
       Executive owns the 180,108 Standard Carried Common Units being purchased
       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.

17.    Except for the changes noted above, the Agreement shall remain in full
       force and effect and any dispute under this Amendment shall be resolved
       in accordance with the terms of the Agreement, including, but not limited
       to, Section 13(g) thereof (Choice of Law).

18.    This Amendment may be executed in any number of counterparts (including
       by means of facsimiled signature pages), which shall together constitute
       one and the same instrument.

                                   * * * * * *
