The following definition of “Section 10b5-1 Plan Redemption” shall be added to its appropriate location in Section 1.1 of the LLC Agreement:

“Section 10b5-1 Plan Redemption” is defined in Section 3.06(a).

The second sentence of Section 3.6(a)(i) of the LLC Agreement is amended as follows (with underlined text to be added):

A Redeeming Member shall be permitted to effect a Redemption of Units no more frequently than once per calendar quarter; provided, however,that, except as otherwise determined by the Managing Member and subject to any such limitations or conditions as the Managing Member may determine, a Redeeming Member shall be permitted to effect a Redemption of Units more frequently than once per calendar quarter in connection with any contract, instruction or written plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) (any such Redemption described in this proviso, a “Section 10b5-1 Plan Redemption”).
