accordance with the provisions of the Act, all other steps shall be
taken which, in the opinion of the General Partner are reasonably necessary to
admit such person under the Act as a substituted Limited Partner, and such
person shall thereupon become a substituted Limited Partner within the meaning
of the Act.

              (c) The General Partners, or any of them, if more than one, may
(but shall not be obligated to) acquire the interest of a Limited Partner, and,
if with respect to such interest, a General Partner becomes a substituted
Limited Partner within the meaning of the Act, the General Partner shall, with
respect to such interest, enjoy all rights and be subject to all of the
obligations and duties of a Limited Partner;

              (d) This Agreement and any securities issued representing an
interest in the Partnership shall bear the following legend:

         "IT IS UNLAWFUL TO CONSUMMATE A SALE OR
         TRANSFER OF THIS SECURITY, OR ANY INTEREST
         THEREIN, OR TO RECEIVE ANY CONSIDERATION
         THEREFOR, WITHOUT THE PRIOR WRITTEN

admit such person under the Act as a substituted Limited Partner, and such
person shall thereupon become a substituted Limited Partner within the meaning
of the Act.

              (c) The General Partners, or any of them, if more than one, may
(but shall not be obligated to) acquire the interest of a Limited Partner, and,
if with respect to such interest, a General Partner becomes a substituted
Limited Partner within the meaning of the Act, the General Partner shall, with
respect to such interest, enjoy all rights and be subject to all of the
obligations and duties of a Limited Partner;

              (d) This Agreement and any securities issued representing an
interest in the Partnership shall bear the following legend:

         "IT IS UNLAWFUL TO CONSUMMATE A SALE OR
         TRANSFER OF THIS SECURITY, OR ANY INTEREST
         THEREIN, OR TO RECEIVE ANY CONSIDERATION
         THEREFOR, WITHOUT THE PRIOR WRITTEN

              ---------------------------------------------
              Partners, as to contributions or as compensation
              ------------------------------------------------
