NUMBER OF UNITS AND DESIGNATION. A class of Partnership Preferred Units is hereby designated as "Class C Partnership Preferred Units," and the number of Partnership Preferred Units constituting such class shall be Two Million Seven Hundred Sixty Thousand (2,760,000). 2. DEFINITIONS. For purposes of the Class C Partnership Preferred Units, the following terms shall have the meanings indicated in this Section 2. Capitalized terms used and not otherwise defined herein shall have the meanings assigned thereto in the Agreement. "AGREEMENT" shall mean the Second Amended and Restated Agreement of Limited Partnership of the Partnership, as amended. "CALL DATE" shall have the meaning set forth in paragraph (a) of Section 5 of this Article. "CLASS C PARTNERSHIP PREFERRED UNIT" means a Partnership Preferred Unit with the designations, preferences and relative, participating, optional or other special rights, powers and duties as are set forth in this EXHIBIT H. It is the intention of the General Partner that each Class C Partnership Preferred Unit shall be substantially the economic equivalent of one share of Class C Preferred Stock. "CLASS C PREFERRED STOCK" means the Class C Cumulative Preferred Stock, par value $0.01 per share, of the Previous General Partner. "CODE" shall mean the Internal Revenue Code of 1986, as amended from time to time, or any successor statute thereto. Reference to any provision of the Code shall mean such provision as in effect from time to time, as the same may be amended, and any successor thereto, as interpreted by any applicable H-1 regulations or other administrative pronouncements as in effect from time to time. "COMMON STOCK" shall mean the Class A Common Stock, $.01 par value per share, of the Previous General Partner or such shares of the Previous General Partner's capital stock into which outstanding shares of Common Stock shall be reclassified.

On every Distribution Payment Date, the holders of Class C Partnership Preferred Units shall be entitled to receive distributions payable in cash in an amount per Class C Partnership Preferred Unit equal to the per share dividend payable on the Class C Preferred Stock on such Distribution Payment Date. Each such distribution shall be payable to the holders of record of the Class C Partnership Preferred Units, as they appear on the records of the Partnership at the close of business on the record date for the dividend payable with respect to the Class C Preferred Stock on such Distribution Payment Date. Holders of Class C Partnership Preferred Units shall not be entitled to any distributions on the Class C Partnership Preferred Units, whether payable in cash, property or stock, except as provided herein. 4. LIQUIDATION PREFERENCE. (a) In the event of any liquidation, dissolution or winding up of the Partnership, whether voluntary or involuntary, before any payment or distribution of H-2 the Partnership (whether capital or surplus) shall be made to or set apart for the holders of Junior Partnership Units, the holders of Class C Partnership Preferred Units shall be entitled to receive Twenty Five Dollars ($25) per Class C Partnership Preferred Unit (the "Liquidation Preference"), plus an amount equal to all dividends (whether or not earned) accumulated, accrued and unpaid on each share of Class C Preferred Stock to the date of final distribution to such holders; but such holders shall not be entitled to any further payment. Until the holders of the Class C Partnership Preferred Units have been paid the Liquidation Preference in full, plus an amount equal to all dividends (whether or not earned) accumulated, accrued and unpaid on the Class C Preferred Stock to the date of final distribution to such holders, no payment will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership. If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Class C Partnership Preferred Units shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any Parity Partnership Units, then such assets, or the proceeds thereof, shall be distributed among the holders of Class C Partnership Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Class C Partnership Preferred Units and any such other Parity Partnership Units if all amounts payable thereon were paid in full. For the purposes of this Section 4, (i) a consolidation or merger of the Partnership with one or more partnerships, or (ii) a sale or transfer of all or substantially all of the Partnership's assets shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Partnership. (b) Upon any liquidation, dissolution or winding up of the Partnership, after payment shall have been made in full to the holders of Class C Partnership Preferred Units and any Parity Partnership Units, as provided in this Section 4, any other series or class or classes of Junior Partnership Units shall, subject to the respective terms thereof, be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Class C Partnership Preferred Units and any Parity Partnership Units shall not be entitled to share therein. 5. REDEMPTION. Class C Partnership Preferred Units shall be redeemable by the Partnership as follows: (a) At any time that the Previous General Partner exercises its right to redeem all or any of the shares of Class C Preferred Stock, the General Partner may cause the Partnership to redeem an equal number of Class C Partnership H-3 Preferred Units, at a redemption price payable in cash equal to 100% of the Liquidation Preference thereof, plus an amount equal to all accrued and unpaid dividends on each share of Class C Preferred Stock to the date fixed for redemption (the "Call Date"), in the manner set forth herein. (b) If the Partnership shall redeem Class C Partnership Preferred Units pursuant to paragraph (a) of this Section 5, from and after the Call Date (unless the Partnership shall fail to make available the amount of cash necessary to effect such redemption), (i) except for payment of the redemption price, the Partnership shall not make any further distributions on the Class C Partnership Preferred Units so called for redemption (except that, in the case of a Call Date after a distribution record date and prior to the related Distribution Payment Date, holders of Class C Partnership Preferred Units on the distribution record date will be entitled on such Distribution Payment Date to receive the distribution payable thereon), (ii) said units shall no longer be deemed to be outstanding, and (iii) all rights of the holders thereof as holders of Class C Partnership Preferred Units of the Partnership shall cease (except the rights to receive the cash payable upon such redemption, without interest thereon, and to receive any distributions payable thereon). No interest shall accrue for the benefit of the holders of Class C Partnership Preferred Units to be redeemed on any cash set aside by the Partnership. If fewer than all the outstanding Class C Partnership Preferred Units are to be redeemed, units to be redeemed shall be selected by the Partnership from outstanding Class C Partnership Preferred Units not previously called for redemption by any method determined by the General Partner in its discretion. Upon any such redemption, the General Partner shall amend EXHIBIT A to the Agreement as appropriate to reflect such redemption. 6. STATUS OF REACQUIRED UNITS. All Class C Partnership Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled. 7. RANKING. Any class or series of Partnership Units of the Partnership shall be deemed to rank: (a) prior or senior to the Class C Partnership Preferred Units, as to the payment of distributions and as to distributions of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the H-4 receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class C Partnership Preferred Units ("Senior Partnership Units"); (b) on a parity with the Class C Partnership Preferred Units, as to the payment of distributions and as to distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class C Partnership Preferred Units if such Class or series of Partnership Units shall be Class B Preferred Partnership Units or if the holders of such class or series of Partnership Units and the Class C Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other ("Parity Partnership Units"); and (c) junior to the Class C Partnership Preferred Units, as to the payment of distributions or as to the distribution of assets upon liquidation, dissolution or winding up, if such class or series of Partnership Units shall be Partnership Common Units or if the holders of Class C Preferred Partnership Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units ("Junior Partnership Units"). 8. SPECIAL ALLOCATIONS. (a) Gross income and, if necessary, gain shall be allocated to the holders of Class C Partnership Preferred Units for any Fiscal Year (and, if necessary, subsequent Fiscal Years) to the extent that the holders of Class C Partnership Preferred Units receive a distribution on any Class C Partnership Preferred Units (other than an amount included in any redemption pursuant to Section 5 hereof) with respect to such Fiscal Year. (b) If any Class C Partnership Preferred Units are redeemed pursuant to Section 5 hereof, for the Fiscal Year that includes such redemption (and, if necessary, for subsequent Fiscal Years) (a) gross income and gain (in such relative proportions as the General Partner in its discretion shall determine) shall be allocated to the holders of Class C Partnership Preferred Units to the extent that the redemption amounts paid or payable with respect to the Class C Partnership Preferred Units so redeemed exceeds the aggregate Capital Contributions (net of liabilities assumed or H-5 taken subject to by the Partnership) per Class C Partnership Preferred Unit allocable to the Class C Partnership Preferred Units so redeemed and (b) deductions and losses (in such relative proportions as the General Partner in its discretion shall determine) shall be allocated to the holders of Class C Partnership Preferred Units to the extent that the aggregate Capital Contributions (net of liabilities assumed or taken subject to by the Partnership) per Class C Partnership Preferred Unit allocable to the Class C Partnership Preferred Units so redeemed exceeds the redemption amount paid or payable with respect to the Class C Partnership Preferred Units so redeemed. 9. RESTRICTIONS ON OWNERSHIP. The Class C Partnership Preferred Units shall be owned and held solely by the General Partner or the Special Limited Partner. 10. GENERAL. (a) The ownership of Class C Partnership Preferred Units may (but need not, in the sole and absolute discretion of the General Partner) be evidenced by one or more certificates. The General Partner shall amend EXHIBIT A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent conversion, redemption, or any other event having an effect on the ownership of, Class C Partnership Preferred Units. (b) The rights of the General Partner and the Special Limited Partner, in their capacity as holders of the Class C Partnership Preferred Units, are in addition to and not in limitation of any other rights or authority of the General Partner or the Special Limited Partner, respectively, in any other capacity under the Agreement or applicable law.
