TWO HUNDRED EIGHTY THIRD AMENDMENT
TO THE
SECOND AMENDED AND RESTATED LIMITED PARTNERSHIP AGREEMENT
OF
SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP

THIS TWO HUNDRED EIGHTY THIRD AMENDMENT TO THE SECOND AMENDED AND RESTATED
LIMITED PARTNERSHIP AGREEMENT OF SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP
(this “Amendment”) is made and entered into on November 14, 2012, by SUN
COMMUNITIES, INC., a Maryland corporation (the “General Partner”), as the
general partner of SUN COMMUNITIES OPERATING LIMITED PARTNERSHIP, a Michigan
limited partnership (the “Partnership”).

RECITALS

A.    Concurrently with the execution of this Amendment, the General Partner is
issuing shares of its 7.125% Series A Cumulative Redeemable Preferred Stock in a
public offering (the “Preferred Stock Offering”).

B.    The General Partner desires to amend that certain Second Amended and
Restated Limited Partnership Agreement of Sun Communities Operating Limited
Partnership, dated as of April 30, 1996, as amended by those certain amendments
numbered one through two hundred eighty two (collectively, as amended, the
“Agreement”) to provide for the issuance of 7.125% Series A Cumulative
Redeemable Preferred Units of the Partnership to the General Partner, in
exchange for the net cash proceeds received by the General Partner in connection
with the Preferred Stock Offering. Any capitalized term used but not otherwise
defined herein shall have the meaning ascribed to it in the Agreement.

C.    Pursuant to that certain Consent Agreement, dated as of October 26, 2012,
the holders of a majority of the Preferred OP Units consented to the
Partnership’s issuance of up to $150 million of OP Units ranking senior to the
Preferred OP Units as to distributions, liquidation preferences, redemption
payments and in all other respects, in connection with preferred stock offerings
from time to time by the General Partner, including the Preferred Stock
Offering.

D.    Section 11 of the Agreement authorizes the General Partner, as the holder
of more than fifty percent (50%) of the OP Units, to amend the Agreement.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises set
forth herein, and of other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the General Partner amends the
Agreement as follows:

1.    Sections 3.1, 3.2 and 3.9. Sections 3.1, 3.2 and 3.9 of the Agreement are
hereby deleted in their entirety and replaced with the following:

“3.1    OP Units

The Partners’ interests in the Partnership are expressed in terms of OP Units
and each Partner has been issued OP Units corresponding to the agreed value of
its capital contribution. OP Units consist of Common OP Units, Preferred OP
Units, Series A-1 Preferred Units, Series B Preferred Units, Series B-1
Preferred Units, Series B-2 Preferred Units, Series B-3 Preferred Units and
Mirror A Preferred Units.

3.2    Common OP Units

1
 

--------------------------------------------------------------------------------

The holders of the Common OP Units shall be entitled to receive distributions in
accordance with Section 4.3, after payment of all accrued (i) Preferred
Dividends, (ii) Series A-1 Priority Return, (iii) Series B Priority Return, (iv)
Series B-1 Priority Return, (v) Series B-2 Priority Return, (vi) Series B-3
Priority Return, and (vii) Mirror A Priority Return. No distribution shall be
made in respect of Common OP Units while any accrued (i) Preferred Dividends,
(ii) Series A-1 Priority Return, (iii) Series B Priority Return, (iv) Series B-1
Priority Return, (v) Series B-2 Priority Return, (vi) Series B-3 Priority
Return, or (vii) Mirror A Priority Return remains unpaid unless all such unpaid
amounts are paid simultaneously with such distribution.

3.9    Withdrawals

No Partner shall be entitled to withdraw any portion of its capital account,
except by way of distributions pursuant to Sections 4.3, 8.2, 16, 17, 18 and 19
hereof.”

2.    The first two sentences of Section 3.6(b) of the Agreement are hereby
deleted in their entirety and replaced with the following: “Upon execution of
this Agreement, the General Partner’s interest in the Partnership comprises
substantially all of its assets, the number of Common OP Units held by the
General Partner equals the number of shares of its outstanding common stock and
the number of Mirror A Preferred Units held by the General Partner equals the
number of outstanding REIT Series A Preferred Shares. It is expected that this
circumstance will continue to exist, since the General Partner intends to
distribute substantially all of its income on a current basis and has agreed to
apply the net proceeds of the sale of additional stock or securities to the
purchase of additional OP Units.”

3.    Section 4.1 of the Agreement is hereby deleted in its entirety and
replaced with the following:

“4.1    Capital Accounts
(a)    The Partnership shall establish and maintain a separate capital account
for each Partner according to the rules of Treasury Regulation Section
1.704‑1(b)(2)(iv) (a “Capital Account”).
(b)    For purposes of computing the amount of any item of Partnership income,
gain, loss or deduction to be allocated pursuant to Section and to be reflected
in the Capital Accounts, “Profits” and “Losses” means, for each Fiscal Year, an
amount equal to the Partnership’s taxable income or loss for such year,
determined in accordance with Section 703(a) of the Code (including all items
required to be stated separately) with the following adjustments:

(i)    The computation of all items of income, gain, loss and deduction shall
include those items described in Code Section 705(a)(l)(B) or Code Section
705(a)(2)(B) and Treasury Regulation Section 1.704‑1(b)(2)(iv)(i), without
regard to the fact that such items are not includable in gross income or are not
deductible for federal income tax purposes.

(ii)    If the Book Value of any Partnership property is adjusted pursuant to
clause (b) of the definition of “Book Value,” the amount of such adjustment
shall be taken into account as gain or loss from the disposition of such
property.
(iii)    Items of income, gain, loss or deduction attributable to the
disposition of Partnership property having a Book Value that differs from its
adjusted basis for tax purposes shall be computed by reference to the Book Value
of such property.
(iv)    Items of depreciation, amortization and other cost recovery deductions
with respect to Partnership property having a Book Value that differs from its
adjusted basis for tax

2
 

--------------------------------------------------------------------------------

purposes shall be computed by reference to the property’s Book Value in
accordance with Treasury Regulation Section 1.704‑1(b)(2)(iv)(g).
(v)    To the extent an adjustment to the adjusted tax basis of any Partnership
asset pursuant to Code Sections 732(d), 734(b) or 743(b) is required, pursuant
to Treasury Regulation Section  1.704‑1(b)(2)(iv)(m), to be taken into account
in determining Capital Accounts, the amount of such adjustment to the Capital
Accounts shall be treated as an item of gain (if the adjustment increases the
basis of the asset) or loss (if the adjustment decreases such basis).
(vi)    Items of income, gain, loss and deduction of the Partnership shall be
computed as if the Partnership had sold any property distributed to a Partner on
the date of such distribution at a price equal to its fair market value at that
date.”
4.    Section 4.2 of the Agreement is hereby deleted in its entirety and
replaced with the following:

“4.2 Profit and Loss Allocations. Except as otherwise provided in Section 4.2.1,
Profits and Losses for any Fiscal Year (or portion thereof) shall be allocated
among the Partners in such a manner that, as of the end of such Fiscal Year (or
other applicable period), the sum of: (a) the Capital Account of each Partner,
(b) such Partner’s share of Minimum Gain (as determined according to Treasury
Regulation Section 1.704-2(g)), and (c) such Partner’s partner nonrecourse debt
minimum gain (as defined in Treasury Regulation Section 1.704-2(i)(3)) shall be
equal to the respective net amounts, positive or negative, that would be
distributed to such Partner or for which such Partner would be liable to the
Partnership under the Partnership Act, determined as if the Partnership were to
(x) liquidate the assets of the Partnership for an amount equal to their
aggregate Book Value (without making any adjustment thereto under clause (b) of
the definition of “Book Value” for such liquidation) and (y) distribute the
proceeds of such liquidation pursuant to Section 8.2”

5.    New Section 4.2.1 of the Agreement is hereby added as follows:

“4.2.1 Special Allocations
(a)    Losses attributable to partner nonrecourse debt (as defined in Treasury
Regulation Section 1.704‑2(b)(4)) shall be allocated in the manner required by
Treasury Regulation Section 1.704‑2(i). If there is a net decrease during a
Fiscal Year in partner nonrecourse debt minimum gain (as defined in Treasury
Regulation Section 1.704‑2(i)(3)), Profits for such Taxable Year (and, if
necessary, for subsequent Taxable Years) shall be allocated to the Partners in
the amounts and of such character as determined according to Treasury Regulation
Section 1.704‑2(i)(4). This Section 4.2.1(a) is intended to be a minimum gain
chargeback provision that complies with the requirements of Treasury Regulation
Section 1.704‑2(i)(4) and shall be interpreted in a manner consistent therewith.
(b)    Nonrecourse deductions (as determined according to Treasury Regulation
Section 1.704‑2(b)(1)) for any Fiscal Year shall be allocated to each Partner
ratably among such Partners based upon their respective holdings of OP Units. If
there is a net decrease in the Minimum Gain during any Taxable Year, each
Partner shall be allocated Profits for such Taxable Year (and, if necessary, for
subsequent Taxable Years) in the amounts and of such character as determined
according to Treasury Regulation Section 1.704‑2(f). This Section 4.2.1(b) is
intended to be a minimum gain chargeback provision that complies with the
requirements of Treasury Regulation Section 1.704‑2(f), and shall be interpreted
in a manner consistent therewith.
(c)    If any Partner that unexpectedly receives an adjustment, allocation or
distribution described in Treasury Regulation Section 1.704‑1(b)(2)(ii)(d)(4),
(5) and (6) has an

3
 

--------------------------------------------------------------------------------

Adjusted Capital Account Deficit as of the end of any Taxable Year, computed
after the application of Sections 4.2.1(a) and 4.2.1(b) but before the
application of any other provision of this Section 4, then Profits for such
Fiscal Year shall be allocated to such Partner in proportion to, and to the
extent of, such Adjusted Capital Account Deficit. This Section 4.2.1(c) is
intended to be a qualified income offset provision as described in Treasury
Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted in a manner
consistent therewith.
(d)    Losses shall not be allocated to a Partner if such allocation of Losses
would cause the Partner to have an Adjusted Capital Account Deficit. Losses that
cannot be allocated to a Partner shall be allocated to the other Partners;
provided, however, that, if no Partner may be allocated Losses due to the
limitations of this Section 4.2.1(d), Losses shall be allocated to the General
Partner.
(e)    If, and to the extent that, any Partner is deemed to recognize any item
of income, gain, loss, deduction or credit as a result of any transaction
between such Partner and the Partnership pursuant to Code Sections 83, 482, 483,
1272‑1274 or 7872 or any similar provision now or hereafter in effect, and the
General Partner determines that any corresponding Profit or Loss of the
Partnership should be allocated to the Partners who recognized such item in
order to reflect the Partners’ economic interests in the Partnership, then the
Partnership may so allocate such Profit or Loss.
(f)    The allocations set forth in Sections 4.2.1(a) through 4.2.1(d) (the
“Regulatory Allocations”) are intended to comply with certain requirements of
Sections 1.704‑1(b) and 1.704‑2 of the Treasury Regulations. The Regulatory
Allocations may not be consistent with the manner in which the Partners intend
to allocate Profit and Loss of the Partnership or make distributions.
Accordingly, notwithstanding the other provisions of this Section 4, but subject
to the Regulatory Allocations, income, gain, deduction, and loss shall be
reallocated among the Partners so as to eliminate the effect of the Regulatory
Allocations and thereby cause the respective Capital Accounts of the Partners to
be in the amounts (or as close thereto as possible) they would have been if
Profit and Loss (and such other items of income, gain, deduction and loss) had
been allocated without reference to the Regulatory Allocations. In general, the
Partners anticipate that this will be accomplished by specially allocating other
Profit and Loss (and such other items of income, gain, deduction and loss) among
the Partners so that the net amount of the Regulatory Allocations and such
special allocations to each such Partner is zero. In addition, if in any Fiscal
Year there is a decrease in partnership minimum gain, or in partner nonrecourse
debt minimum gain, and application of the minimum gain chargeback requirements
set forth in Section 4.2.1(a) or Section 4.2.1(b) would cause a distortion in
the economic arrangement among the Partners, the General Partner may, if it does
not expect that the Partnership will have sufficient other income to correct
such distortion, request the Internal Revenue Service to waive either or both of
such minimum gain chargeback requirements. If such request is granted, this
Agreement shall be applied in such instance as if it did not contain such
minimum gain chargeback requirement.”

6.    New Section 4.2.2 of the Agreement is hereby added as follows:

“4.2.2 Tax Allocations
(a)    Except as provided in Sections 4.2.2(b), (c) and (d), the income, gains,
losses, deductions and credits of the Partnership will be allocated, for
federal, state and local income tax purposes, among the Partners in accordance
with the allocation of such income, gains, losses, deductions and credits among
the Partners for computing their Capital Accounts; except that, if any such
allocation is not permitted by the Code or other applicable law, the
Partnership’s subsequent income, gains, losses, deductions and credits will be
allocated among the Partners so

4
 

--------------------------------------------------------------------------------

as to reflect as nearly as possible the allocation set forth herein in computing
their Capital Accounts.
(b)    Items of Partnership taxable income, gain, loss and deduction with
respect to any property contributed to the capital of the Partnership shall be
allocated among the Partners in accordance with Code Section 704(c) so as to
take account of any variation between the adjusted basis of such property to the
Partnership for federal income tax purposes and its Book Value. In making
allocations pursuant to this Section 4.2.2(b), the General shall apply, in its
sole discretion, any method that may be permitted under Treasury Regulations
Section 1.704-3.
(c)    If the Book Value of any Partnership asset is adjusted pursuant to the
requirements of Treasury Regulation Section 1.704‑1(b)(2)(iv)(e) or (f),
subsequent allocations of items of taxable income, gain, loss and deduction with
respect to such asset shall take account of any variation between the adjusted
basis of such asset for federal income tax purposes and its Book Value in the
same manner as under Code Section 704(c).
(d)    Allocations of tax credits, tax credit recapture, and any items related
thereto shall be allocated to the Partners according to their interests in such
items as determined by the General Partner taking into account the principles of
Treasury Regulation Section 1.704‑1(b)(4)(ii).
(e)    Allocations pursuant to this Section 4.2.2 are solely for purposes of
federal, state and local taxes and shall not affect, or in any way be taken into
account in computing, any Partner’s Capital Account or share of Profits, Losses,
distributions or other Partnership items pursuant to any provision of this
Agreement.”

7.    Section 8.2(a) of the Agreement is hereby deleted in its entirety and
replaced with the following:

“8.2    Liquidating Distributions; Restoration of Capital Account Deficits

Upon the liquidation of the Partnership or any Partner’s interest in the
Partnership, within the meaning of the Treasury Regulations:

(a)    A final allocation of all items of income, gain, loss, and expense shall
be made in accordance with Section 4.2 hereof, and, after payment or provision
for payment of all debts, obligations and other liabilities of the Partnership
to its creditors (including, without limitation, all sales commissions or other
expenses incurred in liquidation), all remaining assets of the Partnership shall
be distributed to the holders of OP Units as follows: (i) first, to the holders
of Mirror A Preferred Units in proportions and amounts equal to the Issue Price
of the Mirror A Preferred Units plus any accrued and unpaid Mirror A Priority
Return thereon; (ii) second, to the holders of the Preferred OP Units and Series
A-1 Preferred Units in proportions and amounts equal to the Issue Prices of
their respective Preferred OP Units and Series A-1 Preferred Units, plus any
accrued and unpaid Preferred Dividends and Series A-1 Priority Return, as the
case may be, thereon; (iii) third, to the holders of the Series B Cumulative
Preferred Units in proportions and amounts equal to the Issue Prices of their
respective Series B Cumulative Preferred Units, plus accrued and unpaid Series B
Priority Return, Series B-1 Priority Return, Series B-2 Priority Return and
Series B-3 Priority Return, as applicable, thereon; and (iv) finally (if any),
to the Common OP Units.”

8.    Section 12 of the Agreement is hereby deleted in its entirety and replaced
with “Intentionally Omitted.”

9.    Section 14 of the Agreement is hereby amended as follows:

5
 

--------------------------------------------------------------------------------

(a)    The definition of “Issue Price” is hereby deleted in its entirety and
replaced with the following: “The ‘Issue Price’ of the OP Units is the value
assigned thereto upon issuance, as set forth in Section 3.6; provided, however,
if the General Partner issues shares of preferred stock and applies all of the
proceeds thereof (net of offering expenses) to the purchase of additional OP
Units, the Issue Price for such OP Units shall be the public offering price per
share for the General Partner’s preferred stock so issued.”

(b)    The second sentence of the definition of “OP Units” is hereby deleted in
its entirety and replaced with the following: “OP Units consist of Common OP
Units, Preferred OP Units, Series A-1 Preferred Units, Series B Preferred Units,
Series B-1 Preferred Units, Series B-2 Preferred Units, Series B-3 Preferred
Units and Mirror A Preferred Units.”

(c)    The definition of “Allocation Regulations” is hereby deleted in its
entirety and replaced with the following: “Treasury Regulations” means the
income tax regulations promulgated under the Code.”

(d)    The definition of “Internal Revenue Code” is hereby deleted in its
entirety and replaced with the following: “Code” means the United States
Internal Revenue Code of 1986, as amended.”

(e)    The following new definitions are inserted in Section 14 (Definitions) so
as to preserve alphabetical order:

“Adjusted Capital Account Deficit” means with respect to any Capital Account as
of the end of any Fiscal Year, the amount by which the balance in such Capital
Account is less than zero. For this purpose, a Partner’s Capital Account balance
shall be: (a) reduced for any items described in Treasury Regulation
Section 1.704‑1(b)(2)(ii)(d)(4), (5), and (6), and (b) increased for any amount
such Partner is obligated to contribute or is treated as being obligated to
contribute to the Partnership pursuant to Treasury Regulation Section
1.704‑1(b)(2)(ii)(c) (relating to partner liabilities to a partnership) or
1.704‑2(g)(1) and 1.704‑2(i) (relating to minimum gain).

“Book Value” means, with respect to any Partnership property, the value of the
property for "book" or Capital Account purposes pursuant to Treasury Regulations
Section 1.704-1(b)(2)(iv). Without limiting the generality of the preceding
sentence: (a) the initial Book Value of any property contributed by a Partner to
the Partnership will be the fair market value of the property on the date of the
contribution, as reasonably determined by the General Partner; and (b) the Book
Value of all Partnership properties shall be adjusted to equal their respective
fair market values (as determined by the General Partner), in accordance with
the rules set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(f),
immediately prior to: (i) the date of the acquisition of any additional interest
in the Partnership by any additional or existing Partner in exchange for more
than a de minimis capital contribution, (ii) the date of the distribution of
more than a de minimis amount of Partnership property to a Partner for an
interest in the Partnership and (iii) in connection with the grant of any OP
Units or any other interest in the Partnership (other than a de minimis
interest) as consideration for the provision of services to or for the benefit
of the Partnership by an existing Partner, or by a new Partner acting in a
Partner capacity or in anticipation of being a Partner; provided, that
adjustments pursuant to clauses (i) and (ii) above shall be made only if the
General Partner reasonably determines that the adjustments are necessary or
appropriate to reflect the relative economic interests of the Partners. The Book
Value of any Partnership property that is distributed to any Partner shall be
adjusted immediately prior to the distribution to equal its fair market value.
If any asset has a Book Value that differs from its adjusted tax basis, then the
Book Value shall be adjusted by the amount of depreciation calculated for
purposes of the definition of “Profits” and “Losses” rather than the amount of
depreciation determined for United States federal income tax purposes.

Units” (the “Mirror A Preferred Units”) is hereby established. The number of
Mirror A Preferred Units shall be 3,450,000 (which number may be decreased (but

--------------------------------------------------------------------------------

Partner). The Issue Price for the Mirror A Preferred Units is Twenty Five
Dollars ($25.00) per unit. The Partnership hereby issues 3,400,000 Mirror A

Section 19.2     Distributions.

A. Payment of Distributions. Subject to the preferential rights of holders of
any class or series of OP Units of the Partnership ranking senior to the Mirror
A Preferred Units, the General Partner, as holder of the Mirror A Preferred
Units, will be entitled to receive, when, as and if declared by the Partnership
acting through the General Partner, out of the Partnership’s available cash,
cumulative preferential cash distributions in an amount equal to the Mirror A
Priority Return. Distributions shall accrue daily, shall accrue and be
cumulative from and including November 14, 2012 and will be payable (i)
quarterly dividing the Mirror A Priority Return by four (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 quarters) in arrears on
January 15, April 15, July 15 and October 15 of each year, commencing January
15, 2013, and (ii) in the event of a redemption of Mirror A Preferred Units, on
the redemption date (each a “Mirror A Preferred Unit Distribution Payment
Date”). Any distribution payable on the Mirror A Preferred Units for a period

Distribution Payment Date is not a Business Day, 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). The distributions payable on any Mirror A Preferred Unit
Distribution Payment Date shall include distributions accrued to but not
including such Mirror A Preferred Unit Distribution Payment Date.

B.Distributions Cumulative. Notwithstanding the foregoing, distributions on the
Mirror A Preferred Units will accrue and be cumulative from November 14, 2012,
whether or not the terms and provisions set forth in Section 19.2 C 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. No
interest, or sum in lieu of interest, will be payable in respect of any
distribution payment or payments on Mirror A Preferred Units which may be in
arrears, and the General Partner, as holder of the Mirror A Preferred Units,
will not be entitled to any distributions, whether payable in cash, securities
or other property, in excess of full cumulative distributions described above.
Any distribution payment made on the Mirror A Preferred Units will first be
credited against the earliest accrued but unpaid distribution due with respect
to the Mirror A Preferred Units. No distributions on the Mirror A Preferred
Units shall be authorized, declared, paid or set apart for payment by the
Partnership at such time as the terms and provisions of any agreement of the
Partnership, including any agreement relating to its indebtedness, directly or
indirectly prohibit authorization, declaration, payment or setting apart for
payment or provide that such authorization, declaration, payment or setting
apart for payment would constitute a breach thereof or a default thereunder, or
if such declaration, payment or setting apart for payment shall be restricted or
prohibited by law.

C.
Priority as to Distributions.

(i)Except as provided in Section 19.2 C (ii) below, unless full cumulative
distributions for all past Mirror A Preferred Unit Distribution Periods on the
Mirror A Preferred Units have been or contemporaneously are authorized and paid
or authorized and a sum sufficient for the payment thereof is set apart for such
payment, no distributions (other than in Common OP Units or any other class or
series of OP Units ranking junior to the Mirror A Preferred Units as to
distributions and as to the distribution of assets upon liquidation, dissolution
and winding up of the Partnership) shall be authorized or paid or set aside for
payment nor shall any other distribution be authorized or made on Preferred OP
Units, Series A-1 Preferred Units, Series B Preferred Units, Series B-1
Preferred Units, Series B-2 Preferred Units, Series B-3 Preferred Units, Common
OP Units or any other classes or series of OP Units ranking junior to or on
parity with the Mirror A Preferred Units as to distributions or as to the
distribution of assets upon liquidation, dissolution or winding up of the
Partnership nor shall any Preferred OP Units, Series A-1 Preferred Units, Series
B

--------------------------------------------------------------------------------

Preferred Units, Series B-1 Preferred Units, Series B-2 Preferred Units, Series
B-3 Preferred Units, Common OP Units or any other classes or series of OP Units
ranking junior to or on parity with the Mirror A Preferred Units as to
distributions or as to the distribution of assets upon liquidation, dissolution
or winding up of the Partnership be redeemed, purchased or otherwise acquired
for any consideration (or any amounts be paid to or made available for a sinking
fund for the redemption of any such units) by the Partnership except: (1) by
conversion into or exchange for Common OP Units or any other classes or series
of OP Units ranking junior to the Mirror A Preferred Units as to distributions
and as to the distribution of assets upon liquidation, dissolution and winding
up of the Partnership, (2) by redemption, purchase or other acquisition of
Common OP Units made for purposes of an incentive, benefit or share purchase
plan for the General Partner, the Partnership or any of their respective
subsidiaries, (3) for redemptions, purchases or other acquisitions of OP Units
by the Partnership in connection with the General Partner’s purchase of its
securities for the purpose of preserving the General Partner’s qualification as
a real estate investment trust for federal income tax purposes, or (4) for any
distributions by the Partnership corresponding to distributions by the General
Partner required for it to maintain its status as a real estate investment trust
for federal income tax purposes. With respect to the Mirror A Preferred Units,
all references in this Article 19 to “past Mirror A Preferred Unit Distribution
Periods” shall mean, as of any date, Mirror A Preferred Unit Distribution
Periods ending on or prior to such date, and with respect to any other class or
series of OP Units ranking on a parity as to distributions with the Mirror A
Preferred Units, all references in this Article 19 to “past distribution
periods” (and all similar references) shall mean, as of any date, distribution
periods with respect to such other class or series of OP Units ending on or
prior to such date.

(ii)When full cumulative distributions for all past Mirror A Preferred Unit
Distribution Periods are not paid in full (or a sum sufficient for such full
payment is not set apart) upon the Mirror A Preferred Units and when full
cumulative distributions for all past distribution periods are not paid in full
(or a sum sufficient for such full payment is not set apart) upon the units of
any other Mirror A Parity Preferred Units ranking on a parity as to
distributions with the Mirror A Preferred Units, then all distributions
authorized on the Mirror A Preferred Units and any other outstanding classes or
series of Mirror A Parity Preferred Units ranking on a parity as to
distributions with the Mirror A Preferred Units shall be declared pro rata so
that the amount of distributions authorized per unit on the Mirror A Preferred
Units and such other classes or series of Mirror A Parity Preferred Units
ranking on a parity as to distributions with the Mirror A Preferred Units shall
in all cases bear to each other the same ratio that accumulated and unpaid
distributions per unit on the Mirror A Preferred Units and such other classes or
series of Mirror A Parity Preferred Units ranking on a parity as to
distributions with the Mirror A Preferred Units (which, in the case of any such
other classes or series of Mirror A Parity Preferred Units ranking on a parity
as to distributions with the Mirror A Preferred Units, shall not include any
accumulation in respect of unpaid distributions for past distribution periods if

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

any corporation, trust or other entity with or into the Partnership) shall not

Section 19.4     Redemption.

A.Redemption. If the General Partner elects to redeem any of the REIT Series A
Preferred Shares in accordance with the terms of the Series A Articles
Supplementary, the Partnership shall, on the date set for redemption of such
REIT Series A Preferred Shares, redeem the number of Mirror A Preferred Units
equal to the number of REIT Series A Preferred Shares for which the General
Partner has given notice of redemption pursuant to Section 5 of Article THIRD of
the Series A Articles Supplementary, at a redemption price, payable in cash,
equal to the product of (i) the number of Mirror A Preferred Units being
redeemed, and (ii) an amount equal to the sum of $25.00, any Preferred
Distribution Shortfall per Mirror A Preferred Unit, and any accrued and unpaid
distribution on the Mirror A Preferred Unit to, but not including, the
redemption date. Any Mirror A Preferred Units so redeemed may be reissued to the
General Partner at such time as the General Partner reissues a corresponding
number of REIT Series A Preferred Shares so redeemed or repurchased, in exchange
for the contribution by the General Partner to the Partnership of the proceeds
from such reissuance of REIT Series A Preferred Shares.

B.Procedures for Redemption. The following provisions set forth the procedures
for redemption:

(i) Notice of redemption will be given by the General Partner to the Partnership
concurrently with the notice of the General Partner sent to the holders of its
REIT Series A Preferred Shares in connection with such redemption. Such notice
shall state: (a) the redemption date; (b) the number of Mirror A Preferred Units
to be redeemed; (c) the redemption price and whether or not accrued and unpaid
distributions will be payable; (d) that distributions on the Mirror A Preferred
Units to be redeemed will cease to accumulate immediately prior to such
redemption date; and (e) whether such redemption is being made pursuant to
Section 5 or 6 of Article THIRD of the Series A Articles Supplementary.

(ii)On or after the redemption date, the General Partner shall present and
surrender the certificates, if any, representing the Mirror A Preferred Units to
the Partnership and thereupon the redemption price of such Mirror A Preferred
Units (including all accumulated and unpaid distributions to but excluding the
redemption date) shall be paid to the General Partner and each surrendered
Mirror A Preferred Unit

10
 

--------------------------------------------------------------------------------

certificate, if any, shall be canceled. If less than all of the Mirror A
Preferred Units represented by any such certificate representing Mirror A
Preferred Units are to be redeemed, a new certificate shall be issued
representing the unredeemed Mirror A Preferred Units.

(iii) From and after the redemption date (unless the Partnership defaults in
payment of the redemption price plus accrued and unpaid distributions to, but
not including, the redemption date), all distributions on the Mirror A Preferred
Units designated for redemption in such notice shall cease to accrue, such
Mirror A Preferred Units shall no longer be deemed outstanding and all rights of
the General Partner will terminate, except the right to receive the redemption
price plus accrued and unpaid distributions to, but not including, the
redemption date. At its election, the Partnership, prior to a redemption date,
may irrevocably deposit the redemption price (including accumulated and unpaid
distributions to but not including the redemption date) of the Mirror A
Preferred Units so called for redemption in trust for the General Partner with a
bank or trust company, in which case the Partnership shall send a notice to the
General Partner which shall (a) state the date of such deposit, (b) specify the
office of such bank or trust company as the place of payment of the redemption
price and (c) require the General Partner to surrender the certificates, if any,
representing such Mirror A Preferred Units at such place on or about the date
fixed in such redemption notice (which may not be later than the redemption
date) against payment of the redemption price (including all accumulated and
unpaid distributions to the redemption date). Any monies so deposited which
remain unclaimed by the General Partner at the end of two years after the
redemption date shall be returned by such bank or trust company to the
Partnership.

Section 19.5      Ranking

    The Mirror A Preferred Units rank, with respect to rights to the payment of
distributions and the distribution of assets in the event of any voluntary or
involuntary liquidation, dissolution or winding up of the Partnership, (i)
senior to all Preferred OP Units, Series A-1 Preferred Units, Series B Preferred
Units, Series B-1 Preferred Units, Series B-2 Preferred Units, Series B-3
Preferred Units, Common OP Units and to all other OP Units other than OP Units
referred to in clauses (ii) and (iii) of this sentence; (ii) on a parity with
all Mirror A Parity Preferred Units and (iii) junior to all OP Units the terms
of which specifically provide that such OP Units rank senior to the Mirror A
Preferred Units with respect to rights to the payment of distributions and the
distribution of assets in the event of any liquidation, dissolution and winding
up of the Partnership. The Partnership shall not issue any OP Units ranking
senior to the Mirror A Preferred Units with respect to, among other things,
rights to the payment of distributions and the distribution of assets in the
event of any liquidation, dissolution and winding up of the Partnership unless
such senior OP Units are issued in connection with a subsequent preferred stock
offering by the General Partner and the General Partner received the requisite
approval of the holders of the REIT Series A Preferred Shares in accordance with
the Series A Articles Supplementary; provided, further, that the terms of such
senior OP Units are substantially similar to the terms of the preferred stock so
offered and issued.

Section 19.6     Voting Rights.

The General Partner shall not have any voting or consent rights in respect of
the Mirror A Preferred Units except as required by applicable law.

Section 19.7     Transfer Restrictions.

The Mirror A Preferred Units shall not be transferable.

Section 19.8     Conversion.

In the event of a conversion of REIT Series A Preferred Shares into REIT Shares
at the option of the holders of REIT Series A Preferred Shares pursuant to the
terms of the Series A Articles Supplementary, then, upon conversion of such REIT
Series A Preferred Shares, the General Partner shall convert a number

11
 

--------------------------------------------------------------------------------

of Mirror A Preferred Units equal to the number of REIT Series A Preferred
Shares so converted into a number of Common OP Units equal to the number of REIT
Shares issued on conversion of such REIT Series A Preferred Shares. In case the
General Partner shall be a party to any transaction (including, without
limitation, a merger, consolidation, share exchange, tender offer for all or
substantially all of the General Partner’s capital stock or sale of all or
substantially all of the General Partner’s assets), in each case as a result of
which the REIT Series A Preferred Shares will be converted into the right to
receive shares of capital stock, other securities or other property (including
cash or any combination thereof), each Mirror A Preferred Unit will thereafter
be convertible under this Section 19.8 into the kind and amount of shares of
capital stock 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 Common OP Units or fraction thereof into which one Mirror A
Preferred Unit was convertible immediately prior to such transaction. In the
event of a conversion of REIT Series A Preferred Shares into REIT Shares, to the
extent the General Partner is required to pay cash in lieu of fractional REIT
Shares pursuant to the Series A Articles Supplementary in connection with such
conversion, the Partnership shall distribute an equal amount of cash to the
General Partner. If a Change of Control Conversion Date (as defined in the
Series A Articles Supplementary) falls after the record date and prior to the
corresponding Mirror A Preferred Unit Distribution Payment Date that has been
duly authorized and declared, each holder of Mirror A Preferred Units converted
under this Section 19.8 shall be entitled to the distribution payable on such
Mirror A Preferred Units on the Mirror A Preferred Unit Distribution Payment
Date notwithstanding the conversion of such Mirror A Preferred Units before that
Mirror A Preferred Unit Distribution Payment Date. Except as expressly provided
in this Section 19.8, the holders of Mirror A Preferred Units shall not have the
right to exchange or convert such Mirror A Preferred Units into REIT Series A
Preferred Shares, REIT Shares or any other securities.

No sinking fund shall be established for the retirement or redemption of Mirror
A Preferred Units.”
