LTIP Units may, in the sole discretion of the General Partner, be issued subject to vesting, forfeiture and additional restrictions on transfer pursuant to the terms of an award, vesting or other similar agreement (a “ Vesting Agreement ”). The terms of any Vesting Agreement may be modified by the General Partner from time to time in its sole discretion, subject to any restrictions on amendment imposed by the relevant Vesting Agreement or by the terms of any plan pursuant to which the LTIP Units are issued, if applicable. LTIP Units that have vested and are no longer subject to forfeiture under the terms of a Vesting Agreement are referred to as “Vested LTIP Units”; all other LTIP Units are referred to as “Unvested LTIP Units.” Subject to the terms of any Vesting Agreement, a holder of LTIP Units shall be entitled to transfer his or her LTIP Units to the same extent, and subject to the same restrictions as holders of Class A Units are entitled to transfer their Class A Units pursuant to Article XI of the Agreement.
