 In addition, if you die during the 90-day period described in Termination of Service above, and a
vested portion of your option has not yet been exercised, then your option will instead expire on the date twelve (12) months after the date of death. In such a case, during the period following your death up to the date twelve (12) months after the
date of death, your estate or heirs may exercise the vested portion of your option.

your Service terminates.

in writing, if the terms of the leave provide for continued Service crediting, or when continued Service crediting is required by applicable law. However, your Service will be treated as terminating 90 days after you went on employee leave, unless
your right to return to active Service is specifically guaranteed by applicable law or by a written contract. Your Service terminates in any event when the approved leave ends unless you immediately return to Service.  The Partnership determines, in its sole discretion, which leaves count for this
purpose.

the Change of Control.

such Units, the Partnership shall have the Right of First Refusal with respect to all (and not less than all) of such Units. If you desire to transfer Units acquired under this Agreement, you must give a written Transfer
Notice to the Partnership describing fully the proposed transfer, including the number of Units proposed to be transferred, the proposed transfer price and the name and address of the proposed transferee.  The Transfer Notice shall be signed both by you and by the proposed new transferee and must
constitute a binding commitment of both parties to the transfer of the Units. The Partnership shall have the right to purchase all, and not less than all, of the Units on the terms of the proposal described in the Transfer Notice (subject, however,
to any change in such terms permitted in the next paragraph) by delivery of a notice of exercise of the Right of First Refusal within thirty (30) days after the date when the Transfer Notice was received by the Partnership.  If the Partnership fails to exercise its Right of First Refusal within thirty (30) days after the
date when it received the Transfer Notice, you may, not later than ninety (90) days following receipt of the Transfer Notice by the Partnership, conclude a transfer of the Units subject to the Transfer Notice on the terms and conditions described in
the Transfer Notice. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent proposed transfer by you, shall again be subject to the Right of First Refusal and shall require
compliance with the procedure described in
