and absolute discretion, for such time (but in any event not more than one

Partnership Units shall be Class One Partnership Preferred Units or (ii) the
holders of such class or series shall be entitled to the receipt of
distributions and of amounts distributable upon liquidation, dissolution or
winding up, as the case may be, in preference or priority to the holders of
Class I Partnership Preferred Units (the Partnership Units referred to in
clauses (i) and (ii) of this paragraph being hereinafter referred to,
collectively, as "Senior Partnership Units");

                  (b) on a parity with the Class I Partnership Preferred Units,
as to the payment of distributions and as to distribution of assets upon
liquidation, dissolution or winding up, whether or not the distribution rates,

denomination thereof be different from those of the Class I Partnership

Partnership Preferred Units, Class J Partnership Preferred Units, Class K
Partnership Preferred Units, Class One Partnership Preferred Units, Class Two

and unpaid distributions per unit or other denomination or liquidation

liquidation, dissolution or winding up, if (i) such class or series of
Partnership Units shall be Partnership Common Units or Class I High Performance

liquidation, dissolution or winding up, as the case may be, in preference or
priority to the holders of such class or series of 


                                      Q-4
   6

Partnership Units (the Partnership Units referred to in clauses (i) and (ii) of
this paragraph being hereinafter referred to, collectively, as "Junior
Partnership Units").

         4.       QUARTERLY CASH DISTRIBUTIONS.

                  (a) Holders of Preferred Units will be entitled to receive,
when and as declared by the General Partner, quarterly cash distributions at the
rate of $0.50 per Preferred Unit; provided, however, that at any time and from
time to time on or after March 1, 2005, the Partnership may adjust the quarterly
cash distribution rate on the Preferred Units to equal 25% of the lower of (i)
two percent (2%) plus the annual interest rate then applicable to U.S. Treasury
notes with a maturity of five years and (ii) the annual dividend rate on the
class or series of preferred stock most recently issued by the Previous General
Partner that (x) is not convertible into another security of the Previous
General Partner at the option of the holder and (y) ranks on a parity with its
Class H Cumulative Preferred Stock. Such adjustment shall become effective upon
the date the Partnership issues a notice to such effect to the holders of the
Preferred Units. Any such distributions will be cumulative from the date of
original issue, whether or not in any distribution period or periods such
distributions have been declared, and shall be payable quarterly on February 15,
May 15, August 15 and November 15 of each year (or, if not a Business Day, the
next succeeding Business Day) (each a "Distribution Payment Date"), commencing
on the first such date occurring after the date of original issue. If the
Preferred Units are issued on any day other than a Distribution Payment Date,
the first distribution payable on such Preferred Units will be prorated for the
portion of the quarterly period that such Preferred Units are outstanding on the
basis of twelve 30-day months and a 360-day year. Distributions will be payable
in arrears to holders of record as they appear on the records of the Partnership
at the close of business on the February 1, May 1, August 1 or November 1, as
the case may be, immediately preceding each Distribution Payment Date. Holders
of Preferred Units will not be entitled to receive any distributions in excess
of cumulative distributions on the 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 Preferred Units that may be in arrears. Holders of any Preferred
Units that are issued after the date of original issuance will be entitled to
receive the same distributions as holders of any Preferred Units issued on the
date of original issuance.

                  (b) When distributions are not paid in full upon the Preferred
Units or any Parity Partnership Units, or a sum sufficient for such payment is
not set apart, all distributions declared upon the Preferred Units and any
Parity Partnership Units shall be declared ratably in proportion to the
respective amounts of distributions accumulated and unpaid on the Preferred
Units and accumulated and unpaid on such Parity Partnership Units. Except as set
forth in the preceding sentence, unless distributions on the Preferred Units
equal to the full amount of accumulated and unpaid distributions have been or
contemporaneously are declared and paid, or declared and a sum sufficient for
the payment thereof has been or contemporaneously is set apart for such payment,
for all past distribution periods, no distributions shall be declared or paid or
set apart for payment by the Partnership with respect to any Parity Partnership
Units.

                  (c) Unless full cumulative distributions (including all
accumulated, accrued and unpaid distributions) on the Preferred Units have been
declared and paid, or declared and set apart for payment, for all past
distribution periods, no distributions (other than distributions paid in Junior
Partnership Units or options, warrants or rights to subscribe for or purchase
Junior Partnership 


                                      Q-5

Units) may be declared or paid or set apart for payment by the Partnership and
no other distribution of cash or other property may be declared or made,
directly or indirectly, by the Partnership with respect to any Junior
Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased
or otherwise acquired (except for a redemption, purchase or other acquisition of
Partnership Common Units made for purposes of an employee incentive or benefit
plan of the Partnership or any affiliate thereof, including, without limitation,
the Previous General Partner and its affiliates) for any consideration (or any
monies be paid to or made available for a sinking fund for the redemption of any
such Junior Partnership Units), directly or indirectly, by the Partnership
(except by conversion into or exchange for Junior Partnership Units, or options,
warrants or rights to subscribe for or purchase Junior Partnership Units), nor
shall any other cash or other property be paid or distributed to or for the
benefit of holders of Junior Partnership Units.

                  (d) Notwithstanding the foregoing provisions of this Section
4, the Partnership shall not be prohibited from (i) declaring or paying or
setting apart for payment any distribution on any Parity Partnership Units or
(ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units,
in each case, if such declaration, payment, redemption, purchase or other
acquisition is necessary to maintain the Previous General Partner's
qualification as a REIT.

         5.       LIQUIDATION PREFERENCE.

                  (a) Upon any voluntary or involuntary liquidation, dissolution
or winding up of the Partnership, before any allocation of income or gain by the
Partnership shall be made to or set apart for the holders of any Junior
Partnership Units, to the extent possible, the holders of Preferred Units shall
be entitled to be allocated income and gain to effectively enable them to
receive a liquidation preference (the "Liquidation Preference") of (i) $25 per
Preferred Unit, plus (ii) accumulated, accrued and unpaid distributions (whether
or not earned or declared) to the date of final distribution to such holders;
but such holders shall not be entitled to any further payment or allocation.
Until all holders of the Preferred Units have been paid the Liquidation
Preference in full, no allocation of income or gain will be made to any holder
of Junior Units upon the liquidation, dissolution or winding up of the
Partnership.

                  (b) If, upon any liquidation, dissolution or winding up of the
Partnership, the assets of the Partnership, or proceeds thereof, distributable
among the holders of Preferred Partnership Units shall be insufficient to pay in
full the Liquidation Preference and liquidating payments on any Parity
Partnership Units, then following certain allocations made by the Partnership,
such assets, or the proceeds thereof, shall be distributed among the holders of
Preferred Units and any such Parity Partnership Units ratably in the same
proportion as the respective amounts that would be payable on such Preferred
Units and any such Parity Partnership Units if all amounts payable thereon were
paid in full.

                  (c) A voluntary or involuntary liquidation, dissolution or
winding up of the Partnership will not include a consolidation or merger of the
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the Partnership's assets.


                                      Q-6
   8

                  (d) Upon any liquidation, dissolution or winding up of the
Partnership, after all allocations shall have been made in full to the holders
of Preferred Units and any Parity Partnership Units to enable them to receive
their respective liquidation preferences, any Junior Partnership Units shall be
entitled to receive any and all assets remaining to be paid or distributed, and
the holders of the Preferred Units and any Parity Partnership Units shall not be
entitled to share therein.

         6.       REDEMPTION.

                  (a) Except as set forth in Sections 6(l) and 6(m) hereof, the
Preferred Units may not be redeemed at the option of the Partnership, and will
not be required to be redeemed or repurchased by the Partnership or the Previous
General Partner except if a holder of a Preferred Unit effects a Redemption, as
provided for in Section 6(b) hereof. The Partnership or the Previous General
Partner may purchase Preferred Units from time to time in the open market, by
tender or exchange offer, in privately negotiated purchases or otherwise.

                  (b) On or after the first (1st) anniversary of becoming a
holder of Preferred Units, a Qualifying Party shall have the right (subject to
the terms and conditions set forth herein) to require the Partnership to redeem
all or a portion of the Preferred Units held by such Qualifying Party (any
Preferred Units tendered for Redemption being hereafter "Tendered Units") in
exchange (a "Redemption") for Common Shares of Preferred Shares issuable on, or
the Cash Amount payable on, the Specified Redemption Date, as determined by the
Partnership in its sole discretion. Any Redemption shall be exercised pursuant
to a Notice of Redemption delivered to the General Partner by the Qualifying
Party when exercising the Redemption right (the "Tendering Party").

                  (c) If the Partnership elects to redeem Tendered Units for
Common Shares or Preferred Shares rather than cash, then the Partnership shall
direct the Previous General Partner to issue and deliver such Common Shares or
Preferred Shares to the Tendering Party pursuant to the terms set forth in this
Section 6, in which case, (i) the Previous General Partner, acting as a distinct
legal entity, shall assume directly the obligation with respect thereto and
shall satisfy the Tendering Party's exercise of its Redemption right, and (ii)
such transaction shall be treated, for federal income tax purposes, as a
transfer by the Tendering Party of such Tendered Units to the Previous General
Partner in exchange for Common Shares or Preferred Shares. In making such
election to cause the Previous General Partner to acquire Tendered Units, the
Partnership shall act in a fair, equitable and reasonable manner that neither
prefers one group or class of Tendering Parties over another nor discriminates
against a group or class of Tendering Parties. If the Partnership elects to
redeem any number of Tendered Units for Common Shares or Preferred Shares,
rather than cash, on the Specified Redemption Date, the Tendering Party shall
sell such number of the Tendered Units to the Previous General Partner in
exchange for (i) a number of Common Shares equal to the Common Shares Amount for
such number of Tendered Units, (ii) if the Preferred Shares are then listed on
the New York Stock Exchange or another national securities exchange, a number of
Preferred Shares equal to such number of Tendered Units, or (iii) any
combination of (i) and (ii). The Tendering Party shall submit (i) such
information, certification or affidavit as the Previous General Partner may
reasonably require in connection with the application of the Ownership Limit and
other restrictions and limitations of the Charter to any such acquisition and
(ii) such written representations, investment letters, legal opinions or other
instruments necessary, in the Previous 


                                      Q-7
   9

General Partner's view, to effect compliance with the Securities Act. The Common
Shares or Preferred Shares shall be delivered by the Previous General Partner as
duly authorized, validly issued, fully paid and non-assessable shares, free of
any pledge, lien, encumbrance or restriction other than the Ownership Limit and
other restrictions provided in the Charter, the Bylaws of the Previous General
Partner, the Securities Act and relevant state securities or "blue sky" laws.
Neither any Tendering Party whose Tendered Units are acquired by the Previous
General Partner pursuant to this Section 6, any Partner, any Assignee nor any
other interested Person shall have any right to require or cause the Previous
General Partner or the General Partner to register, qualify or list any REIT
Shares owned or held by such Person, whether or not such Common Shares or
Preferred Shares are issued pursuant to this Section 6, with the SEC, with any
state securities commissioner, department or agency, under the Securities Act or
the Exchange Act or with any stock exchange; provided, however, that this
limitation shall not be in derogation of any registration or similar rights
granted pursuant to any other written agreement between the Previous General
Partner and any such Person. Notwithstanding any delay in such delivery, the
Tendering Party shall be deemed the owner of such Common Shares or Preferred
Shares for all purposes, including, without limitation, rights to vote or
consent, receive dividends, and exercise rights, as of the Specified Redemption
Date. Common Shares or Preferred Shares issued upon an acquisition of the
Tendered Units by the Previous General Partner pursuant to this Section 6 may
contain such legends regarding restrictions under the Securities Act and
applicable state securities laws as the Previous General Partner in good faith
determines to be necessary or advisable in order to ensure compliance with such
laws.

                  (d) The Partnership shall have no obligation to effect any
redemption unless and until a Tendering Party has given the Partnership a Notice
of Redemption. Each Notice of Redemption shall be sent by hand delivery or by
first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP,
Inc., 1873 South Bellaire Street, 17th Floor, Denver, Colorado 80222, Attention:
Investor Relations, or to such other address as the Partnership shall specify in
writing by delivery to the holders of the Preferred Units in the same manner as
that set forth above for delivery of the Notice of Redemption. At any time prior
to the Specified Redemption Date for any Redemption, any holder may revoke its
Notice of Redemption.

                  (e) A Tendering Party shall have no right to receive
distributions with respect to any Tendered Units (other than the Cash Amount)
paid after delivery of the Notice of Redemption, whether or not the record date
for such distribution precedes or coincides with such delivery of the Notice of
Redemption. If the Partnership elects to redeem any number of Tendered Units for
cash, the Cash Amount for such number of Tendered Units shall be delivered as a
certified check payable to the Tendering Party or, in the General Partner's sole
and absolute discretion, in immediately available funds.

                  (f) In the event that the Partnership declines to cause the
Previous General Partner to acquire all of the Tendered Units from the Tendering
Party in exchange for Common Shares or Preferred Shares pursuant to this Section
6 following receipt of a Notice of Redemption (a "Declination"):


                                      Q-8
   10

                           (1) The Previous General Partner or the General
                  Partner shall give notice of such Declination to the Tendering
                  Party on or before the close of business on the Cut-Off Date.

                           (2) The Partnership may elect to raise funds for the
                  payment of the Cash Amount either (a) by requiring that the
                  Previous General Partner contribute such funds from the
                  proceeds of a registered public offering (a "Public Offering
                  Funding") by the Previous General Partner of a number of
                  Common Shares or Preferred Shares ("Registrable Shares") equal
                  to the Common Shares or Preferred Shares Amount with respect
                  to the Tendered Units or (b) from any other sources
                  (including, but not limited to, the sale of any Property and
                  the incurrence of additional Debt) available to the
                  Partnership.

                           (3) Promptly upon the General Partner's receipt of
                  the Notice of Redemption and the Previous General Partner or
                  the General Partner giving notice of the Partnership's
                  Declination, the General Partner shall give notice (a "Single
                  Funding Notice") to all Qualifying Parties then holding
                  Preferred Units and having Redemption rights pursuant to this
                  Section 6 and require that all such Qualifying Parties elect
                  whether or not to effect a Redemption of their Preferred Units
                  to be funded through such Public Offering Funding. In the
                  event that any such Qualifying Party elects to effect such a
                  Redemption, it shall give notice thereof and of the number of
                  Preferred Units to be made subject thereon in writing to the
                  General Partner within ten (10) Business Days after receipt of
                  the Single Funding Notice, and such Qualifying Party shall be
                  treated as a Tendering Party for all purposes of this Section
                  6. In the event that a Qualifying Party does not so elect, it
                  shall be deemed to have waived its right to effect a
                  Redemption for the next twelve months; provided, however, that
                  the Previous General Partner shall not be required to acquire
                  Preferred Units pursuant to this Section 6(f) more than twice
                  within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash
Amount shall be for the sole benefit of the Previous General Partner and/or the
General Partner. The General Partner and/or the Special Limited Partner shall
make a Capital Contribution of such amounts to the Partnership for an additional
General Partner Interest and/or Limited Partner Interest. Any such contribution
shall entitle the General Partner and the Special Limited Partner, as the case
may be, to an equitable Percentage Interest adjustment.

                  (g) Notwithstanding the provisions of this Section 6, the
Previous General Partner shall not, under any circumstances, elect to acquire
Tendered Units in exchange for the Common Shares or Preferred Shares if such
exchange would be prohibited under the Charter.

                  (h) Notwithstanding anything herein to the contrary, with
respect to any Redemption pursuant to this Section 6:

                           (1) All Preferred Units acquired by the Previous
                  General Partner pursuant to this Section 6 hereof shall be
                  contributed by the Previous General 


                                      Q-9

                  Partner to either or both of the General Partner and the
                  Special Limited Partner in such proportions as the Previous
                  General Partner, the General Partner and the Special Limited
                  Partner shall determine.

                           (2) Subject to the Ownership Limit, no Tendering
                  Party may effect a Redemption for less than five hundred (500)
                  Preferred Units or, if such Tendering Party holds (as a
                  Limited Partner or, economically, as an Assignee) less than
                  five hundred (500) Preferred Units, all of the Preferred Units
                  held by such Tendering Party.

                           (3) Each Tendering Party (a) may effect a Redemption
                  only once in each fiscal quarter of a Twelve-Month Period and
                  (b) may not effect a Redemption during the period after the
                  Partnership Record Date with respect to a distribution and
                  before the record date established by the Previous General
                  Partner for a distribution to its shareholders of some or all
                  of its portion of such Partnership distribution.

                           (4) Notwithstanding anything herein to the contrary,
                  with respect to any Redemption or acquisition of Tendered
                  Units by the Previous General Partner pursuant to this Section
                  6, in the event that the Previous General Partner or the
                  General Partner gives notice to all Limited Partners (but
                  excluding any Assignees) then owning Partnership Interests (a
                  "Primary Offering Notice") that the Previous General Partner
                  desires to effect a primary offering of its equity securities
                  then, unless the Previous General Partner and the General
                  Partner otherwise consent, commencement of the actions denoted
                  in Section 6(f) hereof as to a Public Offering Funding with
                  respect to any Notice of Redemption thereafter received,
                  whether or not the Tendering Party is a Limited Partner, may
                  be delayed until the earlier of (a) the completion of the
                  primary offering or (b) ninety (90) days following the giving
                  of the Primary Offering Notice.

                           (5) Without the Consent of the Previous General
                  Partner, no Tendering Party may effect a Redemption within
                  ninety (90) days following the closing of any prior Public
                  Offering Funding.

                           (6) The consummation of such Redemption shall be
                  subject to the expiration or termination of the applicable
                  waiting period, if any, under the Hart- Scott-Rodino Antitrust
                  Improvements Act of 1976, as amended.

                           (7) The Tendering Party shall continue to own
                  (subject, in the case of an Assignee, to the provision of
                  Section 11.5 of the Agreement) all Preferred Units subject to
                  any Redemption, and be treated as a Limited Partner or an
                  Assignee, as applicable, with respect to such Preferred Units
                  for all purposes of the Agreement, until such Preferred Units
                  are either paid for by the Partnership pursuant to this
                  Section 6 or transferred to the Previous General Partner (or
                  directly to the General Partner or Special Limited Partner)
                  and paid for, by the issuance of the REIT Shares, pursuant to
                  this Section 6 on the Specified Redemption 


                                      Q-10

                  Date. Until a Specified Redemption Date and an acquisition of
                  the Tendered Units by the Previous General Partner pursuant to
                  this Section 6, the Tendering Party shall have no rights as a
                  shareholder of the Previous General Partner with respect to
                  the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this
Section 6(h), all Partnership Common Units and Partnership Preferred Units,
including Preferred Units, beneficially owned by a Related Party of a Tendering
Party shall be considered to be owned or held by such Tendering Party.

                  (i) In connection with an exercise of Redemption rights
pursuant to this Section 6, the Tendering Party shall submit the following to
the General Partner, in addition to the Notice of Redemption:

                           (1) A written affidavit, dated the same date as the
                  Notice of Redemption, (a) disclosing the actual and
                  constructive ownership, as determined for purposes of Code
                  Sections 856(a)(6) and 856(h), of Common Shares or Preferred
                  Shares and any other classes or shares of the Previous General
                  Partner by (i) such Tendering Party and (ii) any Related Party
                  and (b) representing that, after giving effect to the
                  Redemption, neither the Tendering Party nor any Related Party
                  will own Common Shares or Preferred Shares in excess of the
                  Ownership Limit;

                           (2) A written representation that neither the
                  Tendering Party nor any Related Party has any intention to
                  acquire any additional Common Shares, Preferred Shares or any
                  other class of shares of the Previous General Partner prior to
                  the closing of the Redemption on the Specified Redemption
                  Date; and

                           (3) An undertaking to certify, at and as a condition
                  to the closing of the Redemption on the Specified Redemption
                  Date, that either (a) the actual and constructive ownership of
                  Common Shares or Preferred Shares or any other class of shares
                  of the Previous General Partner by the Tendering Party and any
                  Related Party remain unchanged from that disclosed in the
                  affidavit required by Section 6(i)(a) or (b)) after giving
                  effect to the Redemption, neither the Tendering Party nor any
                  Related Party shall own Common Shares or Preferred Shares or
                  other shares of the Previous General Partner in violation of
                  the Ownership Limit.

                  (j) On or after the Specific Redemption Date, each holder of
Preferred Units shall surrender to the Partnership the certificate evidencing
such holder's Preferred Units, at the address to which a Notice of Redemption is
required to be sent. Upon such surrender of a certificate, the Partnership shall
thereupon pay the former holder thereof the applicable Cash Amount and/or
deliver Common Shares or Preferred Shares for the Preferred Units evidenced
thereby. From and after the Specific Redemption Date (i) distributions with
respect to the Preferred Units shall cease to accumulate, (ii) the Preferred
Units shall no longer be deemed outstanding, (iii) the holders thereof shall
cease to be Partners to the extent of their interest in such Preferred Units,
and (iv) all rights whatsoever with respect to the Preferred Units shall
terminate, except the right of the holders of the Preferred Units to receive
Cash Amount and/or Common Shares or Preferred 


                                      Q-11
   13

Shares therefor, without interest or any sum of money in lieu of interest
thereon, upon surrender of their certificates therefor.

                  (k) Notwithstanding the provisions of this Section 6, the
Tendering Parties (i) shall not be entitled to elect or effect a Redemption
where the Redemption would consist of less than all the Preferred Units held by
Partners and, to the extent that the aggregate Percentage Interests of the
Limited Partners would be reduced, as a result of the Redemption, to less than
one percent (1%) and (ii) shall have no rights under the Agreement that would
otherwise be prohibited under the Charter. To the extent that any attempted
Redemption would be in violation of this Section 6(k), it shall be null and void
ab initio, and the Tendering Party shall not acquire any rights or economic
interests in Common Shares or Preferred Shares otherwise issuable by the
Previous General Partner hereunder.

                  (l) Notwithstanding any other provision of the Agreement, on
and after the date on which the aggregate Percentage Interests of the Limited
Partners (other than the Special Limited Partner) are less than one percent
(1%), the Partnership shall have the right, but not the obligation, from time to
time and at any time to redeem any and all outstanding Limited Partner Interests
(other than the Special Limited Partner's Limited Partner Interest) by treating
any Limited Partner as a Tendering Party who has delivered a Notice of
Redemption pursuant to this Section 6 for the amount of Preferred Units to be
specified by the General Partner, in its sole and absolute discretion, by notice
to such Limited Partner that the Partnership has elected to exercise its rights
under this Section 6(l). Such notice given by the General Partner to a Limited
Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of
Redemption delivered to the General Partner by such Limited Partner. For
purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible
to be a Tendering Party) may, in the General Partner's sole and absolute
discretion, be treated as a Tendering Party and (b) the provisions of Sections
6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder
of this Section shall apply, mutatis mutandis.

         7.       STATUS OF REACQUIRED UNITS.

         All Preferred Units which shall have been issued and reacquired in any
manner by the Partnership shall be deemed cancelled and no longer outstanding.

         8.       GENERAL.

         The ownership of the Preferred Units shall be evidenced by one or more
certificates in the form of Annex II hereto. The General Partner shall amend
Exhibit A to the Agreement from time to time to the extent necessary to reflect
accurately the issuance of, and subsequent redemption, or any other event having
an effect on the ownership of, the Preferred Units.

         9.       ALLOCATIONS OF INCOME AND LOSS.

         For each taxable year, (i) each holder of Preferred Units will be
allocated net income of the Partnership in an amount equal to the distributions
made on such holder's Preferred Units during such taxable year, and (ii) each
holder of Preferred Units will be allocated its pro rata share, based 


                                      Q-12
   14

on the portion of outstanding Preferred Units held by it, of any net loss of the
Partnership that is not allocated to holders of Partnership Common Units or
other interests in the Partnership. Upon liquidation, dissolution or winding up
of the Partnership, the holders of Preferred Units will be allocated income and
gain sufficient to enable them to realize the Liquidation Preference in full.

         10.      VOTING RIGHTS.

         Except as otherwise required by applicable law or in the Agreement, the
holders of the Preferred Units will have the same voting rights as holders of
the Partnership Common Units. As long as any Preferred Units are outstanding,
for purposes of determining the Consent of Limited Partners under the Agreement,
the "Majority of Interests of Limited Partners" shall have the meaning set forth
in Section 2 hereof. As long as any Preferred Units are outstanding, in addition
to any other vote or consent of partners required by law or by the Agreement,
the affirmative vote or consent of holders of at least 50% of the outstanding
Preferred Units will be necessary for effecting any amendment of any of the
provisions of the Partnership Unit Designation of the Preferred Units that
materially and adversely affects the rights or preferences of the holders of the
Preferred Units. The creation or issuance of any class or series of Partnership
Units, including, without limitation, any Partnership Units that may have rights
junior to, on a parity with, or senior or superior to the Preferred Units, will
not be deemed to have a material adverse effect on the rights or preferences of
the holders of Preferred Units. With respect to the exercise of the
above-described voting rights, each Preferred Unit will have one (1) vote per
Preferred Unit.

         11.      RESTRICTIONS ON TRANSFER.

         Preferred Units are subject to the same restrictions on transfer
applicable to Common Units, as set forth in the Agreement.
