General Partner shall determine the consideration for and the terns and conditions with respect to any future issuance of interests in the Partnership.

(i)           Within ten (10) days following the issuance of such interests, General Partner or the New Purchaser shall issue to each Buyer a written notice (the “ Notice of Issuance ”) specifying the type and amount of such interests that the Partnership has issued (the “ Issued Interests ”), all of the material terms, including the price (the “ Issued Interest Price ”) at which the Partnership issued the Issued Interests and stating that the Buyers shall have the right to purchase Issued Interests in the manner specified below for the same price per Unit and in accordance with the same terms and conditions specified in such Notice of Issuance.

(iii)        Each Buyer shall have the right to purchase from the New Purchaser up to that percentage of the Issued Interests equal to the Proportionate Share held by such Buyer immediately prior to the issuance of the Issued Interests.

(iv)         Each Buyer shall have a right of oversubscription such that if any other Buyer fails to elect to purchase his or its full Proportionate Share of the Issued Interests, the other Buyer(s) shall, among them, have the right to purchase up to the balance of such Issued Interests not so purchased. The Buyers may exercise such right of oversubscription by electing to purchase more than their Proportionate Share of the Issued Interests by so indicating in their written notice given during the Issuance Ten Day Period. If, as a result thereof, such oversubscription elections exceed the total number of the Issued Interests available in respect to such oversubscription privilege, the oversubscribing Buyers shall be cut back with respect to oversubscriptions on a pro rata basis in accordance with their respective Proportionate Share or as they may otherwise agree among themselves.

(v)          Any Issued Interests that have not been purchased by the Buyers pursuant to the foregoing provisions shall remain owned by the New Purchaser.

(vi)         Notwithstanding anything in this clause (h) to the contrary, in the event the Buyers elect, within the Issuance Ten Day Period, to purchase less than all of the Issued Interests then, in lieu of the Buyers purchasing Issued Interests from the New Purchaser, General Partner may elect to issue directly to such Buyers, for the same type and amount per Issued Interest of cash or non-cash consideration paid by the New Purchaser or cash in an amount equivalent in value to the Issued Interest Price, an equivalent amount of additional securities that are identical to the Issued Interests in all material respects.
