                              SEVENTH AMENDMENT TO

                                    EXHIBIT H
      DESIGNATION OF THE PREFERENCES, RIGHTS, VOTING POWERS, RESTRICTIONS,
                      QUALIFICATIONS AND LIMITATIONS OF THE
                            SERIES B PREFERRED UNITS

         The Series B Preferred Units shall have the following designations,
preferences, rights, powers and duties:

                  (1)      DEFINITIONS. For purposes of this Amendment, (i) the
term "PARITY PREFERRED UNITS" shall be used to refer to any class or series of
Partnership Interests of the Partnership now or hereafter authorized, issued or
outstanding expressly designated by the Partnership to rank on a parity with
Series B Preferred Units (as hereinafter defined) with respect to distributions
and rights upon voluntary or involuntary liquidation, winding-up or dissolution
of the Partnership and include, without limitation, the Series C Preferred Units
(as defined in that certain Fifth Amendment to Third Amended and Restated
Agreement of Limited Partnership of the Partnership, dated as of June 19, 2001)
(the "SERIES C PREFERRED AMENDMENT"), the Series D Preferred Units (as defined
in that certain Sixth Amendment to Third Amended and Restated Agreement of
Limited Partnership of the Partnership, dated as of April 30, 2003) (the "SERIES
D PREFERRED AMENDMENT"), and any other class or series of Preferred Units that
by its terms ranks on a parity with respect to the Series C Preferred Units (as
defined in the Series C Preferred Amendment) or the Series D Preferred Units (as
defined in the Series D Preferred Amendment), (ii) the term "PRIORITY RETURN"
shall mean, an amount equal to 8.875% per annum up to and including February 23,
2004, and 7.25% per annum from and after February 24, 2004, in each case
determined on the basis of a 360 day year of twelve 30 day months (or actual
days for any month which is shorter than a full monthly period), cumulative to
the extent not distributed for any given distribution period pursuant to Section
5.1 of the Partnership Agreement, of the stated value of $50 per Series B
Preferred Unit, commencing on the date of issuance of such Series B Preferred
Unit, (iii) the term "SUBSIDIARY" shall mean with respect to any person, any
corporation, partnership, limited liability company, joint venture or other
entity of which a majority of (x) voting power of the voting equity securities
or (y) the outstanding equity interests, is owned, directly or indirectly, by
such person, (iv) the term "PTP" shall mean a "publicly traded partnership"
within the meaning of Section 7704 of the Code, and (v) the term "RIGHTS" shall
mean those rights granted pursuant to that certain Rights Agreement, dated as of
November 2, 1998 between General Partner and BankBoston, N.A. Capitalized terms
used herein and not otherwise defined herein shall have the meanings ascribed to
them in the Partnership Agreement.

                  (2)      DISTRIBUTIONS.

                  (a) Payment of Distributions. Subject to the rights of holders
of Parity Preferred Units as to the payment of distributions, pursuant to
Section 5.1 of the Partnership Agreement, holders of Series B Preferred Units
shall be entitled to receive, when, as and if declared by the Partnership acting
through the General Partner, out of Available Cash, cumulative preferential cash
distributions at the rate per annum of 8.875% of the original Capital
Contribution per Series B Preferred Unit for the period up to and including
February 23, 2004, and at the rate per annum of 7.25% of the original Capital
Contribution per Series B Preferred Unit for the period from and after February
24, 2004. Such distributions shall be cumulative, shall accrue from the original
date of issuance and will be payable (i) quarterly (such quarterly periods for
purposes of payment and accrual will be the quarterly periods ending on the
dates specified in this sentence and not calendar year quarters) in arrears, on
March 31, June 30, September 30 and December 31 of each year commencing on March
31, 1999 and, (ii) in the event of (A) an exchange of Series B Preferred Units
into Series B Preferred Shares (as hereinafter defined), or (B) a redemption of
Series B Preferred Units, on the exchange date or redemption date, as applicable
(each a "SERIES B PREFERRED UNIT DISTRIBUTION PAYMENT DATE"). The holders of the
Series B Preferred Units acknowledge that all quarterly distributions have been
made through and including the quarterly period ended December 31, 2003. The
amount of the distribution payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months (or actual days for any month which is
shorter than a full monthly period), and for any period shorter than a full
quarterly period for which distributions are computed, the amount of the
distribution payable will be computed on the basis of the actual number of days
elapsed in such a 30-day month. The amount of the distribution payable on March
31, 2004 under the Partnership Agreement and this Exhibit H shall be $1.0277 per
Series B Preferred Unit, representing the conversion of the Priority Return from
8.875% per annum to 7.25% per annum during the quarterly

                                       H-1

<PAGE>

period ended on such date, calculated as follows: (x) the month of January 2004
is counted as a 30-day month with a Priority Return of 8.875% per annum and the
period from and including February 1, 2004 to and including February 23, 2004 is
counted as a 23-day period of a 29-day month with a Priority Return of 8.875%
per annum, (y) the period from and including February 24, 2004 to and including
February 29, 2004 is counted as a six-day period of a 29-day month with a
Priority Return of 7.25% per annum and the month of March 2004 is counted as a
30-day month with a Priority Return of 7.25% per annum, and (z) the amounts for
the periods described in the preceding clauses (x) and (y) were added to obtain
the distribution payable per Series B Preferred Unit on March 31, 2004. If any
date on which distributions are to be made on the Series B Preferred Units is
not a Business Day (as defined herein), then payment of the distribution to be
made on such date will be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of any such delay) except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on such date. Distributions on the Series B
Preferred Units will be made to the holders of record of the Series B Preferred
Units on the relevant record dates to be fixed by the Partnership acting through
the General Partner, which record dates shall in no event exceed fifteen (15)
Business Days prior to the relevant Series B Preferred Unit Distribution Payment
Date (the "SERIES B PREFERRED UNIT PARTNERSHIP RECORD DATE").

                  The term "BUSINESS DAY" shall mean each day, other than a
Saturday or a Sunday, which is not a day on which banking institutions in New
York, New York are authorized or required by law, regulation or executive order
to close.

                  No distributions on the Series B Preferred Units shall be
declared by the General Partner or paid or set apart for payment by the
Partnership at such time as the terms and provisions of any agreement of the
General Partner or the Partnership, including any agreement relating to
indebtedness of either of them, prohibits such declaration, payment, or setting
apart for payment or provides that such declaration, payment or setting apart
for payment would constitute a breach thereof or a default thereunder, or if
such declaration or payment shall be restricted or prohibited by law.

                  (b)      Distributions Cumulative. Distributions on the Series
B Preferred Units will accrue whether or not the terms and provisions of any
agreement of the Partnership, including any agreement relating to its
indebtedness at any time prohibit the current payment of distributions, whether
or not the Partnership has earnings, whether or not there are funds legally
available for the payment of such distributions and whether or not such
distributions are authorized. Accrued but unpaid distributions on the Series B
Preferred Units will accumulate as of the Series B Preferred Unit Distribution
Payment Date on which they first become payable. Distributions on account of
arrears for any past distribution periods may be declared and paid at any time,
without reference to a regular Series B Preferred Unit Distribution Payment Date
to holders of record of the Series B Preferred Units on the record date fixed by
the Partnership acting through the General Partner which date shall not exceed
fifteen (15) Business Days prior to the payment date. Accumulated and unpaid
distributions will not bear interest.

                  (c)      Priority as to Distributions.

                           (i)      So long as any Series B Preferred Units are
outstanding, no distribution of cash or other property shall be authorized,
declared, paid or set apart for payment on or with respect to any class or
series of Partnership Interest ranking junior as to the payment of distributions
or rights upon a voluntary or involuntary liquidation, dissolution or winding-up
of the Partnership to the Series B Preferred Units (collectively, "JUNIOR
UNITS"), nor shall any cash or other property be set aside for or applied to the
purchase, redemption or other acquisition for consideration of any Series B
Preferred Units, any Parity Preferred Units or any Junior Units or Rights in
respect of Junior Units, unless, in each case, all distributions accumulated on
all Series B Preferred Units and all classes and series of outstanding Parity
Preferred Units (or, in the event of the liquidation of the Partnership, to the
extent of respective Capital Account balances of holders of such Series B
Preferred Units and outstanding Parity Preferred Units in accordance with
Section 13.2 of the Partnership Agreement) have been paid in full. The foregoing
sentence will not prohibit (a) distributions payable solely in Junior Units (or
options, warrants or rights to subscribe for Junior Units), (b) the conversion
of Junior Units or Parity Preferred Units into Partnership Interests ranking
junior to the Series B Preferred Units as to distributions and rights upon
voluntary or involuntary liquidation,

                                       H-2

<PAGE>

dissolution or winding up of the Partnership, or (c) the redemption of
Partnership Interests corresponding to any Series B Preferred Shares, Parity
Preferred Shares or Junior Shares to be purchased by the General Partner
pursuant to Article VI of the Declaration of Trust of the General Partner (the
"CHARTER") to preserve the General Partner's status as a real estate investment
trust, provided that such redemption shall be upon the same terms as the
corresponding purchase pursuant to Article VI of the Charter.

                           (ii)     So long as distributions have not been paid
in full (or a sum sufficient for such full payment is not irrevocably deposited
in trust for payment) upon the Series B Preferred Units, all distributions
authorized and declared on the Series B Preferred Units and all classes or
series of outstanding Parity Preferred Units shall be authorized and declared so
that the amount of distributions authorized and declared per Series B Preferred
Unit and such other classes or series of Parity Preferred Units shall in all
cases bear to each other the same ratio that accrued distributions per Series B
Preferred Unit and such other classes or series of Parity Preferred Units (which
shall not include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other, except as would be made
upon a liquidation of the Partnership and a distribution of its assets in
accordance with Section 13.2 of the Partnership Agreement.

                  (d)      No Further Rights. Holders of Series B Preferred
Units shall not be entitled to any distributions, whether payable in cash, other
property or otherwise, in excess of the full cumulative distributions described
herein.

                  (3)      LIQUIDATION PROCEEDS.

                  (a) Upon voluntary or involuntary liquidation, dissolution or
winding-up of the Partnership, distributions on the Series B Preferred Units
shall be made in accordance with Section 13.2 of the Partnership Agreement.

                  (b)      Notice. Written notice of any such voluntary or
involuntary liquidation, dissolution or winding-up of the Partnership, stating
the payment date or dates when, and the place or places where, the amounts
distributable in such circumstances shall be payable, shall be given by (i) fax
and (ii) by first class mail, postage pre-paid, not less than thirty (30) and
not more than sixty (60) days prior to the payment date stated therein, to each
record holder of the Series B Preferred Units at the respective addresses of
such holders as the same shall appear on the transfer records of the
Partnership.

                  (c)      No Further Rights. After payment of the full amount
of the liquidating distributions to which they are entitled, the holders of
Series B Preferred Units will have no right or claim to any of the remaining
assets of the Partnership.

                  (d)      Consolidation, Merger or Certain Other Transactions.
The voluntary sale, conveyance, lease, exchange or transfer (for cash, shares,
securities or other consideration) of all or substantially all of the property
or assets of the General Partner to, or the consolidation or merger or other
business combination of the Partnership with or into, any Company, trust or
other entity (or of any Company, trust or other entity with or into the
Partnership) shall not be deemed to constitute a liquidation, dissolution or
winding-up of the Partnership.

                  (4)      REDEMPTION.

                  (a) Right of Optional Redemption. Except as provided in
Section (4)(d) and Section (6)(a)(ii), the Series B Preferred Units may not be
redeemed prior to February 24, 2009. On or after such date, the Partnership
shall have the right to redeem the Series B Preferred Units, 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, at a redemption price, payable in cash, equal to the
Capital Account balance of the holders of Series B Preferred Units (the "SERIES
B REDEMPTION PRICE"); provided, however, that no redemption pursuant to this
SECTION will be permitted if the Series B Redemption Price does not equal or
exceed the original Capital Contribution of such holder plus the cumulative
Priority Return, whether or not declared, to the redemption date to the extent
not previously distributed. If fewer than all of the outstanding Series

                                       H-3

<PAGE>

B Preferred Units are to be redeemed, the Series B Preferred Units to be
redeemed shall be selected pro rata (as nearly as practicable without creating
fractional units).

                  (b)      Limitation on Redemption.

                           (i)      The Series B Redemption Price (other than
the portion thereof consisting of accumulated but unpaid distributions) will be
payable solely out of the sale proceeds of capital shares of the General
Partner, which will be contributed by the General Partner to the Partnership as
additional capital contribution, or out of the sale of limited partner interests
in the Partnership and from no other source. For purposes of the preceding
sentence, "capital shares" means any equity securities (including Common Shares
and Preferred Shares (as such terms are defined in the Charter)), shares,
participation or other ownership interests (however designated) and any rights
(other than debt securities convertible into or exchangeable for equity
securities) or options to purchase any of the foregoing.

                           (ii)     The Partnership may not redeem fewer than
all of the outstanding Series B Preferred Units unless all accumulated and
unpaid distributions have been paid on all Series B Preferred Units for all
quarterly distribution periods terminating on or prior to the date of
redemption.

                  (c)      Procedures for Redemption.

                           (i)      Notice of redemption will be (A) faxed, and
(B) mailed by the Partnership, by certified mail, postage prepaid, not less than
30 nor more than 60 days prior to the redemption date, addressed to the
respective holders of record of the Series B 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 B Preferred Units except as to the holder to whom such
notice was defective or not given. In addition to any information required by
law, each such notice shall state: (m) the redemption date, (n) the Series B
Redemption Price, (o) the aggregate number of Series B Preferred Units to be
redeemed and if fewer than all of the outstanding Series B Preferred Units are
to be redeemed, the number of Series B 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 B Preferred Units the
total number of Series B Preferred Units held by such holder represents) of the
aggregate number of Series B Preferred Units to be redeemed, (p) the place or
places where such Series B Preferred Units are to be surrendered for payment of
the Series B Redemption Price, (q) that distributions on the Series B Preferred
Units to be redeemed will cease to accumulate on such redemption date and (r)
that payment of the Series B Redemption Price will be made upon presentation and
surrender of such Series B Preferred Units.

                           (ii)     If the Partnership gives a notice of
redemption in respect of Series B Preferred Units (which notice will be
irrevocable) then, by 12:00 noon, New York City time, on the redemption date,
the Partnership will deposit irrevocably in trust for the benefit of the Series
B Preferred Units being redeemed funds sufficient to pay the applicable Series B
Redemption Price and will give irrevocable instructions and authority to pay
such Series B Redemption Price to the holders of the Series B Preferred Units
upon surrender of the Series B Preferred Units by such holders at the place
designated in the notice of redemption. If the Series B Preferred Units are
evidenced by a certificate and if fewer than all Series B Preferred Units
evidenced by any certificate are being redeemed, a new certificate shall be
issued upon surrender of the certificate evidencing all Series B Preferred
Units, evidencing the unredeemed Series B Preferred Units without cost to the
holder thereof. On and after the date of redemption, distributions will cease to
accumulate on the Series B Preferred Units or portions thereof called for
redemption, unless the Partnership defaults in the payment thereof. If any date
fixed for redemption of Series B Preferred Units is not a Business Day, then
payment of the Series B Redemption Price payable on such date will be made on
the next succeeding day that is a Business Bay (and without any interest or
other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the Series B Redemption Price
is improperly withheld or refused and not paid by the Partnership, distributions
on such Series B Preferred Units will continue to accumulate from the original
redemption date to the

                                       H-4

<PAGE>

date of payment, in which case the actual payment date will be considered the
date fixed for redemption for purposes of calculating the applicable Series B
Redemption Price.

                  (d) Mandatory Redemption. Notwithstanding any provision herein
to the contrary (including Section (4)(a)), so long as any Series B Preferred
Units remain outstanding, in the event of the occurrence of a Covered
Transaction (defined below), the Partnership shall redeem, on the date such
Covered Transaction is completed or occurs, all of the Series B Preferred Units
outstanding at the Series B Redemption Price, payable in cash, if redemption of
the Series B Preferred Units was elected in writing by the holders of not less
than a majority of the then outstanding Series B Preferred Units in accordance
with this Section (4)(d). The Partnership shall give written notice of a Covered
Transaction to each of the respective holders of record of the Series B
Preferred Units, at their respective addresses as they appear on the transfer
records of the Partnership, not less than thirty (30) days prior to the
completion or occurrence of a Covered Transaction. Such notice shall not set
forth any non-public information concerning such Covered Transaction. Each of
the holders of record of the Series B Preferred Units shall have until 5:00 p.m.
New York City time, on the fifteenth (15th) day following receipt of such notice
from the Partnership, to give the Partnership notice of such holder's election
that the Series B Preferred Units be redeemed. Notwithstanding any provision
herein to the contrary, with respect to a Covered Transaction that arises under
clause (c) of the definition of Covered Transaction set forth below, in the
event that the General Partner so fails to qualify as a real estate investment
trust for any reason other than an affirmative election by the General Partner
not to qualify, (a) the Partnership shall give notice of the occurrence of a
Covered Transaction to each of the holders of record of the Series B Preferred
Units within 15 days of discovery of such failure to qualify (provided that, if
the General Partner is pursuing administrative relief from the Internal Revenue
Service with respect to such failure to qualify as a real estate investment
trust, such notice shall be given upon the earlier of (1) five days after the
denial of administrative relief by the Internal Revenue Service or (2) 60 days
following the discovery of such failure to qualify), (b) each of the holders of
record of the Series B Preferred Units shall have until 5:00 p.m. New York City
time, on the fifteenth (15th) day following receipt of such notice from the
Partnership, to give the Partnership notice of such holder's election that the
Series B Preferred Units be redeemed or not redeemed (and if any holder of
record of the Series B Preferred Units fails to give the Partnership such notice
of election, then such holder of record shall be deemed to have given a notice
of an election that the Series B Preferred Units be redeemed) and (c) if the
holders of not less than a majority of the then outstanding Series B Preferred
Units have elected to have the Series B Preferred Units redeemed, the Series B
Preferred Units shall be redeemed on a date not later than 30 days following the
date of the Partnership's notice referred to in clause (a) above.

                  The procedures set forth in Section (4)(c) (other than the
requirement that notice of redemption be faxed and mailed not less than 30 days
prior to the redemption date) shall apply to a redemption pursuant to this
Section (4)(d). On or before the date of redemption, the Partnership shall give
notice of redemption to the respective holders of record of the Series B
Preferred Units, at their respective addresses as they appear on the transfer
records of the Partnership.

                  For purposes of this Section (4)(d), the term "Covered
Transaction" shall mean (a) the General Partner's completion of a "Rule 13e-3
transaction" (as defined in Rule 13e-3 under the Securities Exchange Act of
1934, as amended (the "Exchange Act")) in which, as a result of such
transaction, the General Partner 's common stock is no longer registered under
Section 12 of the Exchange Act, except that this clause (a) shall not apply to
any involuntary delisting of the General Partner 's common stock from the New
York Stock Exchange or any national securities exchange (as defined in the
Exchange Act), (b) the completion of any transaction or series of transactions
that would result in a Reorganization Event (defined below) of the General
Partner or the Partnership or (c) the General Partner 's failure (or election
not) to qualify as a real estate investment trust as defined in Section 856 (or
any successor section) of the Internal Revenue Code of 1986, as amended.

                  For purposes of this Section (4)(d), the term "Reorganization
Event" shall mean (x) any sale or other disposition of all or substantially all
of the assets of the Partnership or the General Partner, as the case may be, to
an entity (or more than one entity in related transactions) that is not an
Affiliate of the General Partner; or (y) any consolidation, amalgamation,
merger, business combination, share exchange, reorganization or similar
transaction involving the Partnership or the General Partner, as the case may
be, pursuant to which the Partners of the Partnership or the shareholders of the
General Partner, as the case may be, immediately prior to the consummation

                                       H-5

of such transaction will own less than a majority of the equity interests in the
entity surviving such transaction; provided, however, a Reorganization Event
shall not include any transaction contemplated by clauses (x) or (y) of this
definition if the surviving entity has unsecured debt outstanding which is rated
at least the lowest credit rating level established as investment grade by at
least two of Standard & Poor's, Moody's Investor Service and Fitch Ratings (it
being understood that as of the date hereof the lowest investment grade rating
of Standard & Poor's is BBB-, the lowest investment grade rating of Moody's is
Baa3 and the lowest investment grade rating of Fitch Ratings is BBB-) and such
rating has been reaffirmed in light of the contemplated transaction.

                  (5)      VOTING RIGHTS.

                  (a)      General. Holders of the Series B Preferred Units will
not have any voting rights or right to consent to any matter requiring the
consent or approval of the Limited Partners, except as set forth in Sections 14
of the Partnership Agreement and in this Section.

                  (b)      Certain Voting Rights. So long as any Series B
Preferred Units remain outstanding, the Partnership shall not, without the
affirmative vote of the holders of at least two-thirds of the Series B Preferred
Units outstanding at the time: (i) authorize or create, or increase the
authorized or issued amount of, any class or series of Partnership Interests
ranking prior to the Series B Preferred Units with respect to payment of
distributions or rights upon liquidation, dissolution or winding-up or
reclassify any Partnership Interests into any such Partnership Interest, or
create, authorize or issue any obligations or security convertible into or
evidencing the right to purchase any such Partnership Interests, provided that
the foregoing shall not apply if such class or series is of a priority equal to
either the Series C Preferred Units, the Series D Preferred Units or the Common
Units in all respects but that could have a priority with respect to the Series
B Preferred Units upon a liquidation of the Partnership solely by reason of the
fact that either Section 1.F of Exhibit C to the Partnership Agreement does not
apply to the Series B Preferred Units or the allocation of Net Income provided
for in Section 6.A(iii) precedes the allocation of Net Income provided for in
Section 6.A(iv); (ii) authorize or create, or increase the authorized or issued
amount of any Parity Preferred Units or reclassify any Partnership Interest into
Parity Preferred Units or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any Parity Preferred Units
but only to the extent such Parity Preferred Units are issued to an Affiliate of
the Partnership, unless (A) such Affiliate is the General Partner and such
Parity Preferred Units correspond to preferred shares issued to a nonaffiliate
of the Partnership or (B) such Parity Preferred Units are issued upon terms
determined by the General Partner's Board of Trustees to be no more favorable
than those it would offer in an arm's length transaction to an unrelated party;
or (iii) amend, alter or repeal the provisions of the Partnership Agreement
(including, without limitation, Section 4.2(B) thereof), whether by merger,
consolidation or otherwise, that would materially and adversely affect the
powers, special rights, preferences, privileges or voting power of the Series B
Preferred Units or the holders thereof; provided, however, that with respect to
the occurrence of a merger, consolidation or a sale or lease of all of the
Partnership's assets as an entirety, so long as (1) the Partnership is the
surviving entity and the Series B Preferred Units remain outstanding with the
terms thereof unchanged, (2) the resulting, surviving or transferee entity is a
partnership, limited liability company or other pass-through entity organized
under the laws of any state and substitutes for the Series B Preferred Units
other interests in such entity having substantially the same terms and rights as
the Series B Preferred Units, including with respect to distributions, voting
rights and rights upon liquidation, dissolution or winding-up, or (3) such
merger, consolidation or a sale or lease of all of the Partnership's assets as
an entirety would constitute a Reorganization Event entitling the holders to
elect redemption under Section 4(d) hereof, then the occurrence of any such
event shall not be deemed to materially and adversely affect such rights,
privileges or voting powers of the holders of the Series B Preferred Units; and
provided further that any increase in the amount of Partnership Interests or the
creation or issuance of any other class or series of Partnership Interests, in
each case ranking (y) junior to the Series B Preferred Units with respect to
payment of distributions or the distribution of assets upon liquidation,
dissolution or winding-up, or (z) on a parity to the Series B Preferred Units
with respect to payment of distributions or the distribution of assets upon
liquidation, dissolution or winding-up but only to the extent such Partnership
Interests are issued to an Affiliate of the Partnership unless (A) such
Affiliate is the General Partner and such Parity Preferred Units correspond to
preferred shares issued to a nonaffiliate of the Partnership or (B) such Parity
Preferred Units are issued upon terms determined by the General Partner's Board
of Trustees to be no more favorable than it would offer in an arm's length
transaction to an unrelated party, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers. In the
event of any conflict between the provisions of

                                       H-6

<PAGE>

Section 7.3 or Article 14 of the Partnership Agreement and the provisions of
this Section, the provisions of this Section shall control.

                  (6)      EXCHANGE RIGHTS.

                  (a)      Right to Exchange.

                           (i)      Series B Preferred Units will be
exchangeable in whole or in part at anytime on or after January 1, 2014, at the
option of the holders thereof, for authorized but previously unissued shares of
7.25% Series B Cumulative Redeemable Perpetual Preferred Shares of the General
Partner (the "SERIES B PREFERRED SHARES") at an exchange rate of one share of
Series B Preferred Shares for one Series B Preferred Unit, subject to adjustment
as described below (the "EXCHANGE PRICE"), provided that the Series B Preferred
Units will become exchangeable at any time, in whole or in part, at the option
of the holders of Series B Preferred Units for Series B Preferred Shares if (y)
at any time full distributions shall not have been timely made on any Series B
Preferred Unit with respect to six (6) prior quarterly distribution periods,
whether or not consecutive, provided, however, that a distribution in respect of
Series B Preferred Units shall be considered timely made if made within two (2)
Business Days after the applicable Series B Preferred Unit Distribution Payment
Date if at the time of such late payment there shall not be any prior quarterly
distribution periods in respect of which full distributions were not timely made
or (z) upon receipt by a holder or holders of Series B Preferred Units of (1)
notice from the General Partner that the General Partner or a Subsidiary of the
General Partner has taken the position that the Partnership is, or upon the
occurrence of a defined event in the immediate future will be, a PTP and (2) an
opinion rendered by an outside nationally recognized independent counsel
familiar with such matters addressed to a holder or holders of Series B
Preferred Units, that the Partnership is or likely is, or upon the occurrence of
a defined event in the immediate future will be or likely will be, a PTP. In
addition, the Series B Preferred Units may be exchanged for Series B Preferred
Shares, in whole or in part, at the option of any holder prior to the tenth
(10th) anniversary of the issuance date and after the third anniversary thereof
if such holder of a Series B Preferred Units shall deliver to the General
Partner either (i) a private ruling letter addressed to such holder of Series B
Preferred Units or (ii) an opinion of independent counsel reasonably acceptable
to the General Partner based on the enactment of temporary or final Treasury
Regulations or the publication of a Revenue Ruling, in either case to the effect
that an exchange of the Series B Preferred Units at such earlier time would not
cause the Series B Preferred Units to be considered "shares and securities"
within the meaning of Section 351(e) of the Internal Revenue Code of 1986, as
amended (the "CODE"), for purposes of determining whether the holder of such
Series B Preferred Units is an "investment company" under Section 721(b) of the
Code if an exchange is permitted at such earlier date. Furthermore, the Series B
Preferred Units may be exchanged in whole but not in part (regardless of whether
held by Contributors) for Series B Preferred Shares (but only if the exchange in
whole may be accomplished consistently with the ownership limitations set forth
under Article VI of the Charter of the General Partner, taking into account
exceptions thereto) if at any time, (i) the Partnership reasonably determines
that the assets and income of the Partnership for a taxable year after 1999
would not satisfy the income and assets tests of Section 856 of the Code for
such taxable year if the Partnership were a real estate investment trust within
the meaning of the Code or (ii) any holder of Series B Preferred Units shall
deliver to the Partnership and the Company an opinion of independent counsel
reasonably acceptable to the Company to the effect that, based on the assets and
income of the Partnership for a taxable year after 1999, the Partnership would
not satisfy the income and assets tests of Section 856 of the Code for such
taxable year if the Partnership were a real estate investment trust within the
meaning of the Code and that such failure would create a meaningful risk that a
holder of the Series B Preferred Units would fail to maintain qualification as a
real estate investment trust.

                           (ii)     Notwithstanding anything to the contrary set
forth in SECTION 4 OR (6)(a)(i), if an Exchange Notice (as hereinafter defined)
has been delivered to the General Partner, then the General Partner may, at its
option, elect to redeem or cause the Partnership to redeem all or a portion of
the Series B Preferred Units which are the subject of such Exchange Notice for
cash in an amount equal to the original Capital Contribution per Series B
Preferred Unit redeemed and all accrued and unpaid distributions thereon to the
date of redemption. The General Partner may exercise its option to redeem Series
B Preferred Units for cash pursuant to this SECTION (6)(a)(ii) by giving each
holder of Series B Preferred Units that are to be redeemed notice of its
election to redeem for cash, within five (5) Business Days after receipt of the
Exchange Notice, by (m) fax, and (n) registered mail, postage paid, at the
address of each such holder as it may appear on the records of the Partnership
stating (A) the redemption date,

                                       H-7

<PAGE>

which shall be no later than sixty (60) days following the receipt of the
Exchange Notice, (B) the Series B Redemption Price, (C) the place or places
where the Series B Preferred Units are to be surrendered for payment of the
Series B Redemption Price, (D) that distributions on the Series B Preferred
Units redeemed will cease to accrue on such redemption date; (E) that payment of
the Series B Redemption Price will be made upon presentation and surrender of
the Series B Preferred Units and (F) the aggregate number of Series B Preferred
Units held by such holder that are to be redeemed for cash, which number shall
equal such holder's pro-rata share (based on the percentage of the aggregate
number of Series B Preferred Units that are the subject of such Exchange Notice
that the total number of Series B Preferred Units being redeemed by such holder
represents) of the aggregate number of Series B Preferred Units being redeemed.

                           (iii)    In the event an exchange of all or a portion
of Series B Preferred Units pursuant to SECTION (6)(a)(i) would violate the
provisions on ownership limitation of the General Partner set forth in Article
VI of the Charter of the General Partner with respect to the Series B Preferred
Shares, the General Partner shall give written notice thereof to each holder of
record of Series B Preferred Units, within five (5) Business Days following
receipt of the Exchange Notice, by (m) fax, and (n) registered mail, postage
prepaid, at the address of each such holder set forth in the records of the
Partnership. In such event, each holder of Series B Preferred Units shall be
entitled to exchange, pursuant to the provisions of SECTION (6)(b) a number of
Series B Preferred Units which would comply with the provisions on the ownership
limitation of the General Partner set forth in such Article VI of the Charter of
the General Partner and any Series B Preferred Units not so exchanged (the
"EXCESS UNITS") shall be redeemed by the Partnership for cash in an amount equal
to the original Capital Contribution per Excess Unit, plus any accrued and
unpaid distributions thereon, whether or not declared, to the date of
redemption. The written notice of the General Partner shall state (A) the number
of Excess Units held by such holder, (B) the Series B Redemption Price of the
Excess Units, (C) the date on which such Excess Units shall be redeemed, which
date shall be no later than sixty (60) days following the receipt of the
Exchange Notice, (D) the place or places where such Excess Units are to be
surrendered for payment of the Series B Redemption Price, (E) that distributions
on the Excess Units will cease to accrue on such redemption date, and (F) that
payment of the Series B Redemption Price will be made upon presentation and
surrender of such Excess Units. In the event an exchange would result in Excess
Units, as a condition to such exchange, each holder of such units agrees to
provide representations and covenants reasonably requested by the General
Partner relating to (1) the widely held nature of the interests in such holder,
sufficient to assure the General Partner that the holder's ownership of shares
of the General Partner (without regard to the limits described above) will not
cause any individual to own in excess of 9.8% of the value of the aggregate
shares of the General Partner; and (2) to the extent such holder can so
represent and covenant without obtaining information from its owners, the
holder's ownership of tenants of the Partnership and its affiliates.

                           (iv)     The redemption of Series B Preferred Units
described in SECTION (6)(a)(ii) and (iii) shall be subject to the provisions of
SECTION (4)(b)(i) and SECTION (4)(c)(ii); provided, however, that the term
"Series B Redemption Price" in such Section shall be read to mean the original
Capital Contribution per Series B Preferred Unit being redeemed plus all accrued
and unpaid distributions to the redemption date.

                  (b)      Procedure for Exchange.

                           (i)      Any exchange shall be exercised pursuant to
a notice of exchange (the "EXCHANGE NOTICE") delivered to the General Partner by
the holder who is exercising such exchange right, by (a) fax and (b) by
certified mail postage prepaid. The exchange of Series B Preferred Units, or a
specified portion thereof, may be effected after the tenth (10th) Business Day
following receipt by the General Partner of the Exchange Notice by delivering
certificates, if any, representing such Series B Preferred Units to be exchanged
together with, if applicable, written notice of exchange and a proper assignment
of such Series B Preferred Units to the office of the General Partner maintained
for such purpose. Currently, such office is 2101 Sixth Avenue North, Suite 750,
Birmingham, Alabama 35203. Each exchange will be deemed to have been effected
immediately prior to the close of business on the date on which such Series B
Preferred Units to be exchanged (together with all required documentation) shall
have been surrendered and notice shall have been received by the General Partner
as aforesaid and the Exchange Price shall have been paid. Any Series B Preferred
Shares issued pursuant to this SECTION shall be delivered as shares which are
duly authorized, validly issued, fully paid and nonassessable, free of pledge,
lien,

                                       H-8

encumbrance or restriction other than those provided in the Charter, the Bylaws
of the General Partner, the Securities Act of 1933, as amended, and relevant
state securities or blue sky laws.

                           (ii)     In the event of an exchange of Series B
Preferred Units for shares of Series B Preferred Shares, an amount equal to the
accrued and unpaid distributions, whether or not declared, to the date of
exchange on any Series B Preferred Units tendered for exchange shall (a) accrue
on the shares of the Series B Preferred Shares into which such Series B
Preferred Units are exchanged, and (b) continue to accrue on such Series B
Preferred Units, which shall remain outstanding following such exchange, with
the General Partner as the holder of such Series B Preferred Units.
Notwithstanding anything to the contrary set forth herein, in no event shall a
holder of a Series B Preferred Unit that was validly exchanged into Series B
Preferred Shares pursuant to this section (other than the General Partner now
holding such Series B Preferred Unit), receive a distribution out of Available
Cash of the Partnership, if such holder, after exchange, is entitled to receive
a distribution out of Available Cash with respect to the share of Series B
Preferred Shares for which such Series B Preferred Unit was exchanged or
redeemed.

                           (iii)    Fractional shares of Series B Preferred
Shares are not to be issued upon exchange but, in lieu thereof, the General
Partner will pay a cash adjustment based upon the fair market value of the
Series B Preferred Shares on the day prior to the exchange date as determined in
good faith by the Board of Trustees of the General Partner.

                  (c)      Adjustment of Exchange Price.

                           (i)      The Exchange Price is subject to adjustment
upon certain events, including, (a) subdivisions, combinations and
reclassification of the Series B Preferred Shares, and (b) distributions to all
holders of Series B Preferred Shares of evidences of indebtedness of the General
Partner or assets (including securities, but excluding dividends and
distributions paid in cash out of equity applicable to Series B Preferred
Shares).

                           (ii)     In case the General Partner shall be a party
to any transaction (including, without limitation, a merger, consolidation,
statutory share exchange, tender offer for all or substantially all of the
General Partner's capital shares or sale of all or substantially all of the
General Partner's assets), in each case as a result of which the Series B
Preferred Shares will be converted into the right to receive shares of capital
shares, other securities or other property (including cash or any combination
thereof), each Series B Preferred Unit will thereafter be exchangeable into the
kind and amount of shares of capital shares and other securities and property
receivable (including cash or any combination thereof) upon the consummation of
such transaction by a holder of that number of shares of Series B Preferred
Shares or fraction thereof into which one Series B Preferred Unit was
exchangeable immediately prior to such transaction. The General Partner may not,
without the prior written consent of the holders of at least two-thirds of the
Series B Preferred Units outstanding, become a party to any such transaction
unless the terms thereof are consistent with the foregoing.

                  (7)      NO CONVERSION RIGHTS. The holders of the Series B
Preferred Units shall not have any rights to convert such units into units of
any other class or series of units or into any other securities of, or interest
in, the Partnership.

                  (8)      NO SINKING FUND. No sinking fund shall be established
for the retirement or redemption of Series B Preferred Units.
