The Partnership may not issue on the same terms additional Series D-12 Preferred Units except to the extent issued to all existing holders thereof on an identical per unit basis without the approval of existing holders of Series D-12 Units as set forth herein.

B. Distributions . (i)The holders of the then outstanding Series D-12 Preferred Units shall be entitled to receive, when, as and if declared by the General Partner, distributions payable in cash at the rate per annum of $1.6375 per Series D-12

–3–

Preferred Unit (the “ Annual Distribution Rate ”). Such distributions with respect to each Series D-12 Preferred Unit shall be cumulative from the date of issuance of such Series D-12 Preferred Unit and shall be payable quarterly, when, as and if authorized and declared by the General Partner, in arrears on Distribution Payment Dates, commencing on the first Distribution Payment Date after December 17, 2004. Distributions are cumulative from the most recent Distribution Payment Date to which distributions have been paid; provided that the amount per Series D-12 Preferred Unit to be paid in respect of the initial Distribution Period, or any other period shorter or longer than a full Distribution Period, shall be determined in accordance with paragraph (ii) below. Accumulated and unpaid distributions for any past Distribution Periods may be declared and paid at any time, without reference to any regular Distribution Payment Date.

(ii) The amount of distribution per Series D-12 Preferred Unit accruing in each full Distribution Period shall be computed by dividing the Annual Distribution Rate by four. The amount of distributions payable for the initial Distribution Period, or any other period shorter or longer than a full Distribution Period, on the Series D-12 Preferred Units shall be computed on the basis of twelve 30-day months and a 360-day year. The holders of the then outstanding Series D-12 Preferred Units shall not be entitled to any distributions, whether payable in cash, property or securities, in excess of cumulative distributions, as herein provided, on the Series D-12 Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Series D-12 Preferred Units that may be in arrears.

(iii) So long as any Series D-12 Preferred Units are outstanding, no distributions, except as described in the immediately following sentence, shall be declared or paid or set apart for payment on any series or class or classes of Parity Units (as defined below) for any period unless full cumulative distributions have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Series D-12 Preferred Units for all Distribution Periods terminating on or prior to the distribution payment date on such class or series of Parity Units, except in the case of distributions on the Series B-2 Restricted Preferred Units to the extent not paid due to a lack of funds in the Nongovernmental Account. When distributions are not paid in full or a sum sufficient for such payment is not set apart, as aforesaid, all distributions declared upon Series D-12 Preferred Units and all distributions declared upon any other series or class or classes of Parity Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Series D-12 Preferred Units and such Parity Units, except in the case of distributions on the Series B-2 Restricted Preferred Units to the extent not paid due to a lack of funds in the Nongovernmental Account.

(iv) So long as any Series D-12 Preferred Units are outstanding, no distributions (other than distributions paid solely in Junior Units or options, warrants or rights to subscribe for or purchase Junior Units) shall be declared or paid or set apart for payment or other distribution declared or made upon Junior Units, nor shall any Junior Units be redeemed, purchased or otherwise acquired (other than a redemption, purchase

–4–

or other acquisition of Junior Units made in respect of a redemption, purchase or other acquisition of Common Shares made for purposes of and in compliance with requirements of an employee incentive or benefit plan of the General Partner or any subsidiary, or as permitted under Article VI of the Declaration of Trust of the General Partner), for any consideration (or any moneys to be paid to or made available for a sinking fund for the redemption of any such Junior Units) by the General Partner, directly or indirectly (except by conversion into or exchange for Junior Units), unless in each case (a) the full cumulative distributions on all outstanding Series D-12 Preferred Units and any other Parity Units of the Partnership shall have been paid or set apart for payment for all past Distribution Periods with respect to the Series D-12 Preferred Units and all past distribution periods with respect to such Parity Units, except to the extent that distributions on the Series B-2 Restricted Preferred Units are not then able to be paid owing to a lack of funds in the Nongovernmental Account, and (b) sufficient funds shall have been paid or set apart for the payment of the distribution for the current Distribution Period with respect to the Series D-12 Preferred Units and any Parity Units, except to the extent that distributions on the Series B-2 Restricted Preferred Units are not then able to be paid owing to a lack of funds in the Nongovernmental Account.

C. Liquidation Preference . (i)In the event of any liquidation, dissolution or winding up of the Partnership or the General Partner, whether voluntary or involuntary, before any payment or distribution of the assets of the Partnership shall be made to or set apart for the holders of Junior Units, holders of the Series D-12 Preferred Units shall be entitled to receive an amount equal to the holder’s Capital Account in respect of those Series D-12 Preferred Units; but the holders of Series D-12 Preferred Units shall not be entitled to any further payment. If, upon any such liquidation, dissolution or winding up of the Partnership or the General Partner, the assets of the Partnership, or proceeds thereof, distributable to the holders of Series D-12 Preferred Units, shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any other Parity Units, then such assets, or the proceeds thereof, shall be distributed among the holders of the Series D-12 Preferred Units and the holders of any such other Parity Units ratably in accordance with the respective amounts that would be payable on such Series D-12 Preferred Units and any such other Parity Units if all amounts payable thereon were paid in full. For the purposes of this Section 2.C, (i) a consolidation or merger of the Partnership or the General Partner with one or more entities, (ii) a statutory share exchange by the Partnership or the General Partner and (iii) a sale or transfer of all or substantially all of the Partnership’s or the General Partner’s assets, shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Partnership or General Partner.

(ii) Subject to the rights of the holders of Partnership Units of any series or class or classes of shares ranking on a parity with or prior to the Series D-12 Preferred Units upon any liquidation, dissolution or winding up of the General Partner or the Partnership, after payment shall have been made in full to the holders of the Series D-12 Preferred Units, as provided in this Section, any series or class or classes of Junior Units shall, subject to any respective terms and provisions applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the holder of the Series D-12 Preferred Units shall not be entitled to share therein.

–5–

D. The Partnership’s Right to Redeem the Series D-12 Preferred Units . (i)Except in connection with the redemption of the Series D-12 Preferred Shares by the General Partner as permitted by Article VI of the Declaration of Trust or as set forth in Section E below, the Series D-12 Preferred Units shall not be redeemable prior to December 17, 2009. On and after December 17, 2009, the General Partner may, at its option, cause the Partnership to redeem the Series D-12 Preferred Units in whole or in part, as set forth herein, subject to the provisions described below, at a redemption price, payable in cash, in an amount equal to $25 per unit for the Series D-12 Preferred Units being redeemed (the “ Redemption Price ”). Upon any such redemption, the Partnership shall also pay any accumulated and unpaid distributions owing in respect of the Series D-12 Preferred Units being redeemed.

(ii) Such Series D-12 Preferred Units as are not held by the General Partner may be redeemed by the Partnership on or after December 17, 2009, in whole or in part, at any time or from time to time, upon not less than 30 nor more than 60 days’ written notice. If fewer than all of the outstanding Series D-12 Preferred Units that are not held by the General Partner are to be redeemed, the Series D-12 Preferred Units to be redeemed from each holder (other than the General Partner) shall be selected pro rata (as nearly as practicable without creating fractional units). Any notice of redemption delivered pursuant to this Section D(ii) will be (x) faxed and (y) mailed by the Partnership, by certified mail, postage prepaid, not less than 30 nor more than 60 days prior to the date upon which such redemption is to occur (the “ Third Party Redemption Date ”), addressed to each holder of record of the Series D-12 Preferred Units at their respective addresses as they appear on the records of the Partnership. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series D-12 Preferred Units. In addition to any information required by law, each such notice shall state: (a) the Third Party Redemption Date, (b) the amount payable per Series D-12 Preferred Unit upon redemption, including the Redemption Price and any amount payable pursuant to Section D(iv) hereof, (c) the aggregate number of Series D-12 Preferred Units to be redeemed and, if fewer than all of the outstanding Series D-12 Preferred Units are to be redeemed, the number of Series D-12 Preferred Units to be redeemed held by such holder, which number shall equal such holder’s pro rata share (based on the percentage of the aggregate number of outstanding Series D-12 Preferred Units not held by the General Partner that the total number of Series D-12 Preferred Units held by such holder represents and determined as nearly as practicable without creating fractional interests) of the aggregate number of Series D-12 Preferred Units to be redeemed, (d) the place or places where such Series D-12 Preferred Units are to be surrendered for payment of the amount payable upon redemption and (e) that payment of such amount will be made upon presentation and surrender of such Series D-12 Preferred Units. If the Partnership gives a notice of redemption in respect of Series D-12 Preferred Units pursuant to this Section D(ii), then, by 12:00 noon, New York City time, on the Third Party Redemption Date, the Partnership will deposit irrevocably in trust for the

–6–

benefit of the holders of Series D-12 Preferred Units being redeemed funds sufficient to pay the applicable amount payable with respect to such Series D-12 Preferred Units and will give irrevocable instructions and authority to pay such amount to the holders of the Series D-12 Preferred Units upon surrender of the Series D-12 Preferred Units by such holders at the place designated in the notice of redemption.

(iii) Such Series D-12 Preferred Units as may be held by the General Partner may be redeemed, in whole or in part, at the option of the General Partner, at any time, upon payment by the Partnership to the General Partner of the Redemption Price and any amount payable pursuant to Section D(iv) hereof with respect to such Series D-12 Preferred Units; provided that the General Partner shall redeem an equivalent number of Series D-12 Preferred Shares. Such redemption of Series D-12 Preferred Units shall occur substantially concurrently with the redemption by the General Partner of such Series D-12 Preferred Shares (such date is herein referred to collectively with the Third Party Redemption Date as the “ Redemption Date ”).

(iv) Upon any redemption of Series D-12 Preferred Units, the Partnership shall pay any accrued or accumulated and unpaid distributions for any Distribution Period, or any other period shorter than a full Distribution Period, ending on or prior to the Redemption Date. On and after the Redemption Date, distributions will cease to accumulate on the Series D-12 Preferred Units called for redemption, unless the Partnership defaults in payment therefor. If any date fixed for redemption of Series D-12 Preferred Units is not a Unit Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day that is a Unit Business Day (and without any interest or other payment in respect of any such delay) except that, if such Unit Business Day falls in the next calendar year, such payment will be made on the immediately preceding Unit Business Day, in each case with the same force and effect as if made on such date fixed for redemption. If payment of the Redemption Price is improperly withheld or refused and not paid by the Partnership, distributions on such Series D-12 Preferred Units will continue to accumulate from the original redemption date to the date of payment, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the applicable Redemption Price. Except as provided above, the Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on Series D-12 Preferred Units called for redemption under this Section 2.D.

(v) If full cumulative distributions on the Series D-12 Preferred Units and any other series or class or classes of Parity Units of the Partnership have not been paid or declared and set apart for payment, except in connection with a purchase, redemption or other acquisition of Series D-12 Preferred Shares or shares of beneficial interest ranking on a parity with such Series D-12 Preferred Shares as permitted under Article VI of the Declaration of Trust and except to the extent that such distributions or amounts distributable on the Series B-2 Restricted Preferred Units may not be payable due to a lack of funds in the Nongovernmental Account, the Series D-12 Preferred Units may not be redeemed in part and the Partnership may not purchase, redeem or otherwise acquire Series D-12 Preferred Units or any Parity Units other than in exchange for Junior Units.

–7–

As promptly as practicable after the surrender of any such Series D-12 Preferred Units so redeemed, such Series D-12 Preferred Units shall be exchanged for the amount of cash (without interest thereon) payable therefor pursuant to Section 2.D(i). If fewer than all the Series D-12 Preferred Units represented by any physical certificate are redeemed, then the Partnership shall issue new certificates representing the unredeemed Series D-12 Preferred Units without cost to the holder thereof.

E. Series D-12 Preferred Unit Holder Redemption Right.

(i) General . (a)Subject to paragraphs (ii) and (iii) below, on or after the Series D-12 Effective Date, the holder of the Series D-12 Preferred Units shall have the right (the “ Series D-12 Redemption Right ”) to require the Partnership to redeem the Series D-12 Preferred Units on any Series D-12 Specified Redemption Date in cash in an amount equal to the holder’s Capital Account after the Carrying Values of all Partnership assets are adjusted pursuant to Section 1.D of Exhibit B to the Agreement and the holder’s Capital Account is adjusted accordingly for the Series D-12 Preferred Units being redeemed. Any such Series D-12 Redemption Right shall be exercised pursuant to notice of redemption comparable to the Notice of Redemption required under Section 8.6 of the Agreement (a “ Series D-12 Notice of Redemption ”) delivered to the Partnership (with a copy to the General Partner) by the Limited Partner who is exercising the Series D-12 Redemption Right (the “ Series D-12 Redeeming Partner ”). Except in the event of the occurrence of the circumstance described in clause (z) of the definition of “Series D-12 Effective Date”, a holder of the Series D-12 Preferred Units may only exercise the Series D-12 Redemption Right in respect of all Series D-12 Preferred Units held by such holder on the date of the applicable Series D-12 Redemption Notice. In addition, any redemption pursuant to the Series D-12 Redemption Right shall be subject to all of the provisions of the Agreement governing redemptions under Section 8.6 of the Agreement as if it were a redemption under that section, except as otherwise provided herein. Notwithstanding the foregoing to the contrary and in light of the General Partner’s rights under clause (ii) below, the provisions of Section 8.6 of the Agreement shall not apply to any redemption of the Series D-12 Preferred Units.

(b) The Series D-12 Redeeming Partner shall have no right with respect to any Series D-12 Preferred Units so redeemed to receive any distributions paid after the Series D-12 Specified Redemption Date, unless the record date for the distribution preceded the Series D-12 Specified Redemption Date. If the record date for such distribution was a date prior to the Series D-12 Specified Redemption Date and the Distribution Payment Date in respect of such distribution was a date after the Series D-12 Specified Redemption Date, such Series D-12 Redeeming Partner shall be required, as a condition of the redemption of such Series D-12 Preferred Units, to pay the amount of such distribution to the Partnership (if such Series D-12 Preferred Units are redeemed for cash) or to the General Partner (if such Series D-12 Preferred Units are redeemed for Series D-12 Preferred Shares).

–8–

(c) The Assignee of any Limited Partner may exercise the rights of such Limited Partner pursuant to this Section 2.E, and such Limited Partner shall be deemed to have assigned such rights to such Assignee and shall be bound by the exercise of such rights by such Limited Partner’s Assignee. In connection with any exercise of such rights by such Assignee on behalf of such Limited Partner, the Redemption Price and any accumulated and unpaid distributions shall be paid by the Partnership directly to such Assignee and not to such Limited Partner.

(ii) General Partner Assumption of Right . (a)If the holder of the Series D-12 Preferred Units has delivered a Series D-12 Notice of Redemption, the General Partner may, in its sole and absolute discretion (subject to any limitations on ownership and transfer of Shares set forth in the Declaration of Trust), elect to assume directly and satisfy the Series D-12 Redemption Right by paying to the Redeeming Partner either (x) an amount equal to the holder’s Capital Account for the Series D-12 Preferred Units being redeemed after the Carrying Values of all Partnership assets are adjusted pursuant to Section 1.D of Exhibit B to the Agreement and the holder’s Capital Account is adjusted accordingly or (y) in the form of Series D-12 Preferred Shares, as set forth in paragraph (b) below provided , however , that if and to the extent that after giving effect only to the Series D-12 Preferred Units acquired by a holder from the Partnership on the date of initial issuance such exchange would, based solely on the Series D-12 Preferred Shares acquired by such holder directly from the General Partner in satisfaction of a Series D-12 Redemption Right and those Series D-12 Preferred Shares acquired in prior exercises of the Series D-12 Redemption Right, result in the Series D-12 Preferred Shares being delivered in satisfaction of the Series D-12 Redemption Right being issued to such holder as “Excess Stock” (as such term is used in Article VI of the REIT’s declaration of Trust), then, so long as any waiver granted pursuant to Section 6.6(l) of the Declaration of Trust of the ownership limits that includes such holder shall have been terminated in accordance with its terms, the General Partner shall instead satisfy such Series D-12 Redemption Right by paying the Redeeming Partner the amount specified in clause (x) in respect thereof. Unless the General Partner, in its sole and absolute discretion, shall exercise its right to assume directly and satisfy the Series D-12 Redemption Right, the General Partner shall not have any obligation to the Redeeming Partner or to the Partnership with respect to the Redeeming Partner’s exercise of the Series D-12 Redemption Right. In the event the General Partner shall exercise its right to satisfy the Series D-12 Redemption Right in the manner described in the first sentence of this paragraph (ii) and shall fully perform its obligations in connection therewith, the Partnership shall have no right or obligation to pay any amount to the Redeeming Partner with respect to such Redeeming Partner’s exercise of the Series D-12 Redemption Right, and each of the Redeeming Partner, the Partnership and the General Partner shall, for federal income tax purposes, treat the transaction between the General Partner and the Redeeming Partner as a sale of the Redeeming Partner’s Partnership Units to the General Partner. Nothing contained in this paragraph (ii) shall imply any right of the General Partner to require any holder of Series D-12 Preferred Units to exercise the Series D-12 Redemption Right afforded pursuant to paragraph (i) above.

–9–

(b) In the event that the Partnership redeems Series D-12 Preferred Units for cash in accordance with Section 2.E(i)(a), the units so redeemed shall be terminated. In the event that the General Partner determines to pay the Redeeming Partner in the form of Series D-12 Preferred Shares, the General Partner shall issue to the Series D-12 Redeeming Partner one Series D-12 Preferred Share for each Series D-12 Preferred Unit being redeemed (subject to modification as set forth in paragraph (c) below and subject to adjustment in the case of splits, subdivisions or combinations of the Series D-12 Preferred Shares that do not result in an appropriate adjustment to the Series D-12 Preferred Units), whereupon the General Partner shall acquire the Series D-12 Preferred Units offered for redemption by the Series D-12 Redeeming Partner and shall be treated for all purposes of the Agreement as the owner of such Series D-12 Preferred Units. Any accumulated and unpaid distributions on such Series D-12 Preferred Units to the date of such redemption shall also be deemed to be accrued and to have accumulated on the Series D-12 Preferred Shares paid to the Series D-12 Redeeming Partner in consideration of such Series D-12 Preferred Units at the time of the issuance of such Series D-12 Preferred Shares.

(c) In the event that there shall be outstanding at any time both Series D-12 Preferred Shares and Series D-12 Preferred Units and the General Partner shall be a party to any transaction (including, without limitation, a merger, consolidation or statutory share exchange with respect to the Series D-12 Preferred Shares), in each case as a result of which the Series D-12 Preferred Shares are converted into the right to receive shares of capital stock, other securities or other property (including cash or any combination thereof), thereafter the Redemption Price payable by the General Partner in respect of one Series D-12 Preferred Unit shall be the kind and amount of shares of capital stock and other securities and property (including cash or any combination thereof) that was received upon consummation of such transaction in return for one Series D-12 Preferred Share; and the General Partner may not become a party to any such transaction unless the terms thereof are consistent with the foregoing. In case there shall be outstanding Series D-12 Preferred Units and no Series D-12 Preferred Shares and the General Partner shall be a party to any merger or consolidation in which the General Partner is not the surviving entity, then the Series D-12 Preferred Shares deliverable by the General Partner thereafter in redemption of Series D-12 Preferred Units pursuant to clause (ii) above shall be shares of the surviving entity or any entity controlling the surviving entity having the preferences, rights, voting powers, restrictions, limitations as to dividends, qualifications and terms and conditions of redemption substantially similar to those set forth on Schedule 1 to this Exhibit AB .

(d) Each Redeeming Partner agrees to execute such documents as the General Partner may reasonably require in connection with the issuance of Series D-12 Preferred Shares upon exercise of the Series D-12 Redemption Right.

–10–

(iii) Exceptions to Exercise of Redemption Right . Notwithstanding the provisions of paragraphs (i) and (ii) above, a Partner shall not be entitled to exercise the Series D-12 Redemption Right if (but only as long as) the delivery of Series D-12 Preferred Shares to such Partner on the Series D-12 Specified Redemption Date (a) would be prohibited under the Declaration of Trust, or (b) as long as the Common Shares or any previously issued Series D-12 Preferred Shares are Publicly Traded, would be prohibited under applicable federal or state securities laws or regulations (assuming the General Partner would in fact assume and satisfy the Series D-12 Redemption Right).

(iv) No Liens on Partnership Units Delivered for Redemption . Each holder of any Series D-12 Preferred Units covenants and agrees with the General Partner that all Series D-12 Preferred Units delivered for redemption shall be delivered to the Partnership or the General Partner, as the case may be, free and clear of all liens, and, notwithstanding anything contained herein to the contrary, neither the General Partner nor the Partnership shall be under any obligation to acquire Series D-12 Preferred Units which are or may be subject to any liens. Each holder of Series D-12 Preferred Units further agrees that, in the event any state or local property transfer tax is payable as a result of the transfer of its Series D-12 Preferred Units to the Partnership or the General Partner, such holder shall assume and pay such transfer tax.

F. Conversion . The Series D-12 Preferred Units are not convertible into or redeemable or exchangeable for any other property or securities of the General Partner Entity or the Partnership at the option of any holder of Series D-12 Preferred Units, except as provided in Sections D and E hereof.

(a) prior to the Series D-12 Preferred Units, as to the payment of distributions and as to distribution of assets upon liquidation, dissolution or winding up of the General Partner or the Partnership, if the holders of such class or series of Partnership Units shall be entitled to the 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 Series D-12 Preferred Units;

(a) The Series D-12 Preferred Units shall be Preference Units and shall receive distributions on a basis pari passu with other Partnership Units, if any, receiving distributions pursuant to Section 5.1.B(i) of the Agreement, except to the extent that distributions on the Series B-2 Restricted Preferred Units may not be paid due to a lack of funds in the Nongovernmental Account.

C. Liquidation Preference . (i) In the event of any liquidation, dissolution or winding up of the Partnership or the General Partner, whether voluntary or involuntary, before any payment or distribution of the assets of the Partnership shall be made to or set apart for the holders of Junior Units, the General Partner, in its capacity as the holder of the Series G Preferred Units, shall be entitled to receive Twenty-Five Dollars ($25.00) per Series G Preferred Unit (the “ Liquidation Preference ”) plus an amount equal to all distributions (whether or not earned or declared) accrued and unpaid thereon to the date of final distribution to the General Partner, in its capacity as such holder; but the General Partner, in its capacity as the holder of Series G Preferred Units, shall not be entitled to any further payment. If, upon any such liquidation, dissolution or winding up of the Partnership or the General Partner, the assets of the Partnership, or proceeds thereof, distributable to the General Partner, in its capacity as the holder of Series G Preferred Units, shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any other Parity Units, then such assets, or the proceeds thereof, shall be distributed among the General Partner, in its capacity as the holder of such Series G Preferred Units, and the holders of any such other Parity Units ratably in accordance with the respective amounts that would be payable on such Series G Preferred Units and any such other Parity Units if all amounts payable thereon were paid in full. For the purposes of this Section C, (i) a consolidation or merger of the Partnership or the General Partner with one or more entities, (ii) a statutory share exchange by the Partnership or the General Partner and (iii) a sale or transfer of all or substantially all of the Partnership’s or the General Partner’s assets, shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Partnership or General Partner.

(ii) Subject to the rights of the holders of Partnership Units of any series or class or classes of shares ranking on a parity with or prior to the Series G Preferred Units upon any liquidation, dissolution or winding up of the General Partner or the Partnership, after payment shall have been made in full to the General Partner, in its capacity as the holder of the Series G Preferred Units, as provided in this Section, any series or class or classes of Junior Units shall, subject to any respective terms and provisions applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the General Partner, in its capacity as the holder of the Series G Preferred Units, shall not be entitled to share therein.

D. Redemption of the Series G Preferred Units . (i) Except in connection with the redemption of the Series G Preferred Shares by the General Partner as permitted by the Declaration of Trust, the Series G Preferred Units shall not be redeemable prior to December 22, 2009. On and after December 22, 2009, the General Partner may, at its option, cause the Partnership to redeem the Series G Preferred Units for cash, in whole or in part, as set forth herein, subject to the provisions described below.

(ii) The Series G Preferred Units may be redeemed, in whole or in part, at the option of the General Partner, in its capacity as the holder of the Series G Preferred Units, at any time, provided that the General Partner shall redeem an equivalent number of Series G Preferred Shares. Such redemption of Series G Preferred Units shall occur substantially concurrently with the redemption by the General Partner of such Series G Preferred Shares (the “ Redemption Date ”).

(iii) Upon redemption of Series G Preferred Units by the General Partner on the Redemption Date, each Series G Preferred Unit so redeemed shall be converted into the right to receive Twenty-Five Dollars ($25.00) per Series G Preferred Unit, plus any accrued and unpaid distributions with respect to the Series G Preferred Units to the Redemption Date (the “ Redemption Price ”).

Upon any redemption of Series G Preferred Units, the Partnership shall pay any accrued and unpaid distributions in arrears for any Distribution Period ending on or prior to the Redemption Date. If the Redemption Date falls after a Dividend Payment Record Date and prior to the corresponding Dividend Payment Date, then the General Partner, in its capacity as the holder of Series G Preferred Units, shall be entitled to distributions payable on the equivalent number of Series G Preferred Units as the number of the Series G Preferred Shares with respect to which the General Partner shall be required, pursuant to the terms of the Declaration of Trust, to pay to the holders of Series G Preferred Shares at the close of business on such Dividend Payment Record Date for the Series G Preferred Shares who, pursuant to such Declaration of Trust, are entitled to the dividend payable on such Series G Preferred Shares on the corresponding Dividend Payment Date notwithstanding the redemption of such Series G Preferred Shares before such Dividend Payment Date. Except as provided above, the Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on Series G Preferred Units called for redemption.

(iv) If full cumulative distributions on the Series G Preferred Units and any other series or class or classes of Parity Units of the Partnership have not been paid or declared and set apart for payment, except in connection with a purchase, redemption or other acquisition of Series G Preferred Shares or shares of beneficial interest ranking on a parity with such Series G Preferred Shares as permitted under the Declaration of Trust and except to the extent that such distributions or amounts distributable on the Series B-2 Restricted Preferred Units may not be payable due to a lack of funds in the Nongovernmental Account, the Series G Preferred Units may not be redeemed in part and the Partnership may not purchase, redeem or otherwise acquire Series G Preferred Units or any Parity Units other than in exchange for Junior Units.

As promptly as practicable after the surrender of the certificates for any such Series G Preferred Units so redeemed, such Series G Preferred Units shall be exchanged for the cash (without interest thereon) for which such Series G Preferred Units have been redeemed. If fewer than all the Series G Preferred Units evidenced by any certificate are redeemed, the Partnership shall issue new certificates evidencing the unredeemed Series G Preferred Units without cost to the holder thereof.
