Q:   WHAT IS THE RELATIONSHIP BETWEEN AIMCO AND YOUR PARTNERSHIP?
    
 
   
A:   In June, 1997, we acquired the general partner of your partnership. In
     1997, we also acquired a 95% non-voting interest in the company that
     manages the property owned by your partnership.
    
 
   
Q:   WHY IS THE OFFER BEING MADE?
    
 
   
A:   We are in the business of acquiring direct and indirect interests in
     apartment properties. The offer provides us with an opportunity to increase
     our ownership interest in the property owned by your partnership. The offer
     also provides you and other investors in your partnership with an
     opportunity to liquidate your current investment and to invest in our
     securities or receive cash, or to retain your units.

Q:   WHAT ARE TAX-DEFERRAL   % PREFERRED OP UNITS?
    
 
   
A:   Tax-Deferral   % Preferred OP Units are a class of our Partnership
     Preferred Units. Tax-Deferral   % Preferred OP Units are not listed on any
     national securities exchange nor quoted on the NASDAQ System. There is no
     active trading market for Tax-Deferral   % Preferred OP Units and none is
     likely to develop because they are subject to restrictions on transfer.
    
 
   
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL   %
     PREFERRED OP UNITS?
    
 
   
A:   There are four principal advantages of exchanging your units for
     Tax-Deferral   % Preferred OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral   % Preferred OP Units. Upon redemption, we will
       give you, at our option, shares of AIMCO's Class I Preferred Stock,
       shares of AIMCO's Class A Common Stock or cash. AIMCO's Class A Common
       Stock is, and AIMCO's Class I Preferred Stock is expected to be, listed
       and traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral   % Preferred OP
       Units.
    
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $               per unit on the Tax-Deferral   %
       Preferred OP Units before any distributions are paid to holders of Tax-
       Deferral Common OP Units. Your partnership has not paid any distributions
       on your units since the inception of your partnership.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.
    
 
   
Q:   WHAT ARE TAX-DEFERRAL COMMON OP UNITS?
    
 
   
A:   The Tax-Deferral Common OP Units are our Partnership Common Units.
     Tax-Deferral Common OP Units are not listed on any national securities
     exchange nor quoted on the NASDAQ System. There is no active trading market
     for Tax-Deferral Common OP Units and none is likely to develop because they
     are subject to restrictions on transfer.
    
 
   
Q:   WHAT ARE THE ADVANTAGES TO ME OF EXCHANGING UNITS FOR TAX-DEFERRAL COMMON
     OP UNITS?
    
 
   
A:   There are five principal advantages of exchanging your units for
     Tax-Deferral Common OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units. Upon redemption, we will give
       you, at our option, shares of AIMCO's Class A Common Stock (on a
       one-for-one basis, subject to adjustment in certain circumstances) or an
       equivalent amount of cash. AIMCO's Class A Common Stock is listed and
       traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
    
 
   
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
    
 
   
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than your partnership.

Q:   WHAT IS THE ADVANTAGE OF TENDERING UNITS FOR CASH?
    
 
   
A:   Immediate liquidity. If you tender your units for cash, you will receive
     $     per unit. However, tendering your units for cash may cause you to
     recognize taxable gain for federal income tax purposes.
    
 
   
Q:   HOW DO THE DISTRIBUTIONS ON MY UNITS COMPARE WITH THE DISTRIBUTIONS I WILL
     RECEIVE IF I EXCHANGE MY UNITS FOR TAX-DEFERRAL   % PREFERRED OP UNITS OR
     TAX-DEFERRAL COMMON OP UNITS?
    
 
   
A:   Your partnership did not pay any distributions on your units in 1998. We
     will pay fixed quarterly distributions of $               per unit on the
     Tax-Deferral   % Preferred OP Units before any distributions are paid to
     holders of Tax-Deferral Common OP Units. We pay quarterly distributions on
     the Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
     paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
     (equivalent to $2.25 on an annual basis).
    
 
   
Q:   WHAT ARE THE DISADVANTAGES AND RISKS I SHOULD CONSIDER?
    
 
   
A:   We determined our offer price without any arms-length negotiations. Thus,
     the offer price may not necessarily reflect the value of your units if they
     were sold to someone else or if the assets of your partnership were
     liquidated and the net proceeds distributed to you and your partners. If
     you tender your units for cash, you may have to pay taxes. If you tender
     your units in exchange for Tax-Deferral   % Preferred OP Units or
     Tax-Deferral Common OP Units, the nature of your investment will change
     from holding an interest in a single property to holding an interest in an
     operating business that owns and manages a large portfolio of properties,
     with risks that do not exist for your partnership. You should review the
     risk factors starting in this Prospectus Supplement and in the accompanying
     Prospectus.
    
 
   
Q:   WHAT ARE THE TAX CONSEQUENCES OF THE OFFER TO ME?
    
 
   
A:   You will generally not recognize any immediate taxable gain or loss for
     federal income tax purposes if you exchange your units solely in exchange
     for Tax-Deferral   % Preferred OP Units or Tax-Deferral Common OP Units.
     You will generally recognize a taxable gain or loss for federal income tax
     purposes on units you sell for cash. The exchange of your units for OP
     Units and cash will be treated, for federal income tax purposes, as a
     partial sale of such units and as a partial tax-free contribution of such
     units to our operating partnership.
    
 
   
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
     INCOME TAX CONSEQUENCES OF TENDERING YOUR UNITS IN THE OFFER. THIS SUMMARY
     DOES NOT DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE
     RELEVANT TO YOU IN LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE
     SUBJECT TO SPECIAL TREATMENT UNDER THE FEDERAL INCOME TAX LAWS. THE
     PARTICULAR TAX CONSEQUENCES OF THE OFFER TO YOU WILL DEPEND ON A NUMBER OF
     FACTORS RELATED TO YOUR TAX SITUATION. YOU SHOULD REVIEW "CERTAIN FEDERAL
     INCOME TAX MATTERS" IN THIS PROSPECTUS SUPPLEMENT AND IN THE ACCOMPANYING
     PROSPECTUS AND CONSULT YOUR TAX ADVISORS FOR A FULL UNDERSTANDING OF THE
     TAX CONSEQUENCES TO YOU OF THE OFFER.
    
 
   
Q:   WHAT ARE MY ALTERNATIVES TO TENDERING UNITS?
    
 
   
A:   As alternatives to tendering your units, you may retain your units or,
     subject to the terms of your partnership agreement, seek a private sale of
     your units. However, your partnership agreement contains certain
     restrictions on the resale of your units, and the market for your units may
     be limited. Your partnership agreement prohibits any transfer of an
     interest if such transfer, together with all other transfers during the
     preceding 12 months, would cause 50% or more of the total interest in your
     partnership to be transferred within such 12-month period. If we acquire a
     significant percentage of the interest in your partnership, you may not be
     able to transfer your units for a 12-month period following the offer.
    
 
   
Q:   WHAT HAPPENS IF I DON'T TENDER MY UNITS?
    
 
   
A:   If you choose to retain your units, your investment will remain unchanged.
     However, if we acquire additional interests in your partnership, we will
     increase our ability to influence voting decisions with respect to your
     partnership.

Q:   WHAT ARE MY UNITS WORTH?
    
 
   
A:   The general partner of your partnership has received an opinion of an
     independent firm that our offer price of $          in cash per unit is
     fair. However, your units are not listed on any national securities
     exchange nor quoted on the NASDAQ System, and there is no established
     trading market for your units. Secondary sales activity for the units has
     been limited and sporadic. Your general partner does not monitor or
     regularly receive or maintain information regarding the prices at which
     secondary sale transactions in the units have been effectuated. In August,
     1997, we offered to acquire all units of your partnership at a price of
     $2,648 in cash per unit. In June, 1998, we offered to acquire all units of
     your partnership at a price of $21,668 in cash per unit.
    
 
   
Q:   HOW WAS THE OFFER PRICE FOR MY UNITS DETERMINED?
    
 
   
A:   We determined the offer price by estimating the proceeds that you would
     receive if your partnership were liquidated. For this purpose, we estimated
     the value of the property owned by your partnership using the direct
     capitalization method. This method involves applying a capitalization rate
     to your partnership's annual net operating income. However, there are a
     number of available methods to value real estate, each of which requires
     judgments about certain variables. We used our best judgment for these
     variables, but our valuation is ultimately an estimate. The proceeds that
     you would receive if you sold your units to someone else or if your
     partnership were actually liquidated might be higher or lower than our
     offer price. An actual liquidation may also result in your paying taxes.
    
 
   
Q:   HAS THERE BEEN ANY INDEPENDENT EVALUATION OF THE FAIRNESS OF THE OFFER?
    
 
   
A:   We have retained Robert A. Stanger & Co., Inc. to conduct an analysis of
     the offer and to render an opinion as to the fairness to you of the offer
     price. Stanger is not affiliated with us or your general partner. Stanger
     is one of the leaders in the field of analyzing and evaluating complex real
     estate transactions. However, we provided much of the information used by
     Stanger in evaluating our offer. We believe that the information we
     provided to Stanger is accurate.
    
 
   
Q:   DOES MY GENERAL PARTNER RECOMMEND THAT I TENDER MY UNITS?
    
 
   
A:   Your general partner is affiliated with us and, therefore, has substantial
     conflicts of interest with respect to our offer. Accordingly, your general
     partner makes no recommendation to you as to whether to tender or refrain
     from tendering any of your units in the offer. However, your general
     partner believes that you should make your decision based on a number of
     factors, including your financial position, your risk profile, your desire
     for liquidity, other financial opportunities available to you and your tax
     position.
    
 
   
Q:   WHAT DO I NEED TO DO NOW?
    
 
   
A:   First, you should read this Prospectus Supplement and the accompanying
     Prospectus thoroughly and discuss it with your financial and tax advisors.
     Second, you should decide if you want to tender any of your units and, if
     so, whether you prefer to receive Tax-Deferral   % Preferred OP Units,
     Tax-Deferral Common OP Units, cash or a combination. Third, if you do want
     to tender any of your units, you should fill out the Letter of Transmittal
     that accompanies these materials and send it to the Information Agent
     listed on the back cover of this Prospectus Supplement.
    
 
   
Q:   WHEN WILL THE OFFER BE COMPLETED AND WHEN WILL I RECEIVE TAX-DEFERRAL   %
     PREFERRED OP UNITS, TAX-DEFERRAL COMMON OP UNITS OR CASH?
    
 
   
A:   You have until                  , 1998 to send your Letter of Transmittal
     to the Information Agent. As soon as practicable after the
       , 1998 deadline, we will deliver to you the Tax-Deferral   % Preferred OP
     Units, Tax-Deferral Common OP Units or cash to which you are entitled.
     However, we reserve the right to extend, terminate or amend the offer and,
     under certain circumstances, to delay payment for your units.

Q:   CAN I CHANGE MY MIND AFTER I HAVE SENT MY LETTER OF TRANSMITTAL TO THE
     INFORMATION AGENT?
    
 
   
A:   Yes. You can withdraw your Letter of Transmittal or submit a new one,
     changing the number of units you wish to tender or the form of payment you
     choose to receive. However, you must do this before the expiration of the
     offer, and you must follow the instructions provided with the Letter of
     Transmittal and any instructions of the Information Agent.
    
 
   
Q:   WHOM DO I CONTACT FOR ADDITIONAL INFORMATION OR IF I HAVE QUESTIONS?
    
 
   
A:   You should feel free to contact the Information Agent by phone, fax or

THE AIMCO OPERATING PARTNERSHIP
    
 
   
     AIMCO Properties, L.P. is the "AIMCO Operating Partnership." It conducts
substantially all of the operations of AIMCO. AIMCO is a real estate investment
trust that owns and manages multifamily apartment properties throughout the
United States. As of June 30, 1998, we were the second largest owner and manager
of multifamily apartment properties in the United States, with a total portfolio
of 200,911 apartment units in 1,045 properties located in 42 states, the
District of Columbia and Puerto Rico. As of June 30, 1998, we:
    
 
   
     - owned or controlled 58,345 units in 210 apartment properties;
    
 
   
     - held an equity interest in 74,318 units in 478 apartment properties; and
    
 
   
     - managed 68,248 units in 357 apartment properties for third party owners
       and affiliates.
    
 
   
     In May 1998, we entered into a merger agreement with Insignia Financial
Group, Inc. and Insignia/ESG Holdings, Inc., which was approved by our
stockholders and those of Insignia on September 14. When the Insignia merger is
completed, we will become the largest owner and manager of apartment properties
in the country, with 397,646 units in 2,272 properties. Our principal executive
offices are located at 1873 South Bellaire Street, Denver, Colorado 80222, and
our telephone number is (303) 757-8101.
    
 
   
THE OFFER
    
 
   
     We are offering to acquire up to      of the outstanding units of your
partnership. In exchange for each of your units, we are offering you a choice
of:
    
 
   
     -        of our Tax-Deferral      % Preferred OP Units;
    
 
   
     -        of our Tax-Deferral Common OP Units; or
    
 
   
     - $          in cash;
    
 
   
in each case, subject to reduction for any distribution subsequently made by
your partnership prior to the expiration of our offer.
    
 
   
     We will only accept a maximum of      % of the outstanding units in
response to our offer. If more units are tendered to us, we will generally
accept units on a pro rata basis according to the number of units tendered by
each person. Our offer is not subject to any minimum number of units being
tendered.
    
 
   
     Our offer will expire at 5:00 p.m., Denver, Colorado time, on
  , 1998, unless we extend the deadline.
    
 
   
RISK FACTORS
    
 
   
     You should carefully consider the risks set forth under "Risk Factors"
beginning on page S-28 of this Prospectus Supplement and on page 5 of the
accompanying Prospectus. The primary risks associated with the offer are as
follows:
    
 
   
     NO THIRD PARTY VALUATION OR APPRAISAL. We did not use any third-party
appraisal or valuation to determine the value of your partnership's property. We
established the terms of our offer, including the
    
 
                                       S-7
<PAGE>   12
 
   
exchange ratios and the cash consideration, without any arms-length
negotiations. We have retained Robert A. Stanger & Co., Inc. to conduct an
analysis of our offer and to render an opinion as to the fairness to you of our
offer price, from a financial point of view.
    
 
   
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your partnership
property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of your partnership property, our
offer price could be substantially less than the net proceeds that you would
realize upon a future liquidation of your partnership. Accordingly, you might
receive more value if you retain your units until your partnership is
liquidated. However, you may prefer to receive the offer price now rather than
wait for uncertain future net liquidation proceeds.
    
 
   
     OFFER PRICE MAY NOT REPRESENT FAIR MARKET VALUE. There is no established or
regular trading market for your units, nor is there another reliable standard
for determining the fair market value of the units. If you need or desire
liquidity, you may wish to consider the offer. However, the offer price does not
necessarily reflect the price that you would receive in an open market for your
units or upon a liquidation of your partnership's assets. Such prices could be
higher or lower than the offer price.
    
 
   
     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to our offer.
    
 
   
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. You will not receive
any future distributions on units that we acquire from you. If you elect to
receive our OP Units in exchange for your units, you will be entitled to future
distributions from us. Although your partnership did not make any distributions
in 1998, it might make distributions in the future.
    
 
   
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, if you exchange your units
for our OP Units, it will not be a taxable transaction. If you sell your units
for cash, you will recognize taxable gain or loss in an amount equal to the
difference between the amount realized on the exchange and your adjusted tax
basis in your units. If you exchange your units for both OP Units and cash, it
will be treated, for federal income tax purposes, as a partial taxable sale of
such units for cash and as a partial tax-free contribution of such units to our
operating partnership. If you tender your units for cash or for both OP Units
and cash, the "amount realized" will be measured by the sum of the cash received
plus the portion of your partnership's liabilities allocated to the units sold
for federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of your partnership's liabilities exceeds your tax
basis for the units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. See "Certain Federal Income Tax Matters."
    
 
   
     The particular tax consequences to you of the exchange will depend upon a
number of factors related to your individual tax situation, including your tax
basis in your units, whether you dispose of all of your units in your
partnership, and whether the "passive" loss rules apply to your investments.
Because the income tax consequences of an exchange of units will not be the same
for everyone, you should consult your tax advisor before determining whether to
tender your units pursuant to our offer.
    
 
   
     CERTAIN TAX RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS. There are
certain tax risks associated with the acquisition of, holding and disposing of
OP Units. Although your general partner has no present intention to liquidate or
sell your partnership's property or prepay the current mortgage on the property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you exchange your
units for OP Units. See "Federal Income Taxation of the AIMCO Operating
Partnership and Unitholders," in the accompanying Prospectus.
    
 
   
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
units for our OP Units, you will have changed fundamentally the nature of your
investment from an interest in a partnership that owns and manages a single
property, to an interest in a partnership that invests in and manages a large
portfolio of properties.
    
 
                                       S-8
<PAGE>   13
 
   
     UNCERTAINTY OF PUBLIC TRADING MARKET. We cannot predict the price at which
our stock will trade in the future. Recently, there have been declines in the
trading prices for many REIT equity securities, including ours.
    
 
   
     COMPANY AUTHORITY. If you tender your units for OP Units, you will have
less effective power in influencing our policies than you currently have in
influencing the policies of your partnership.
    
 
   
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your partnership
agreement prohibits any transfer of an interest if such transfer, together with
all other transfers during the preceding 12 months, would cause 50% or more of
the total interest in your partnership to be transferred within such 12-month
period. If we acquire a significant percentage of the interest in your
partnership, you may not be able to transfer your units for a 12-month period
following our offer.
    
 
   
     UNCERTAIN FUTURE DISTRIBUTIONS. Although our operating partnership makes
quarterly distributions based on its available cash, there can be no assurance
regarding the amounts of available cash that our operating partnership will
generate or the portion that we will choose to distribute.
    
 
   
     LIMITATIONS ON CHANGE OF CONTROL. Our charter has restrictions on the
ownership of our equity securities in order to comply with certain REIT tax
requirements. The limited partners of the AIMCO Operating Partnership are unable
to remove the general partner of the AIMCO Operating Partnership or to vote in
the election of AIMCO's directors unless they own shares of AIMCO. As a result,
our limited partners and stockholders are limited in their ability to effect a
change of control of the AIMCO Operating Partnership and AIMCO.
    
 
   
     POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES. We have been,
and continue to be, involved in various transactions with a number of our
affiliates, including executive officers, directors, and entities in which they
own interests. For example, for certain REIT purposes, Messrs. Considine and
Kompaniez directly or indirectly control the companies that manage properties
for third parties and affiliates. Although we own a 95% non-voting interest in
these management companies, we have no control over them or their operations. As
a result, the management companies could implement business decisions or
policies that are not in our best interests. We have adopted certain policies
designed to minimize or eliminate the conflicts of interest inherent in these
transactions, including a requirement that a majority or our disinterested
directors approve certain transactions with affiliates. However, there can be no
assurance that these policies will be successful in eliminating the influence of
such conflicts. Furthermore, such policies are subject to change without the
approval of our stockholders.
    
 
   
     CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITY. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the AIMCO GP and its affiliates, on the one hand, and the AIMCO
Operating Partnership or any partner thereof, on the other. The directors and
officers of the AIMCO GP have fiduciary duties to AIMCO, as the sole stockholder
of the AIMCO GP. At the same time, the AIMCO GP, as general partner of the AIMCO
Operating Partnership, has fiduciary duties to the AIMCO Operating Partnership's
partners.
    
 
   
     LACK OF TRADING MARKET FOR OP UNITS. There is no public market for our OP
Units. In addition, the AIMCO Operating Partnership Agreement restricts the
transferability of OP Units. We have no plans to list the OP Units on a
securities exchange. It is unlikely that any person will make a market in the OP
Units, or that an active market for the OP Units will develop.
    
 
   
     LIMITED VOTING RIGHTS OF HOLDERS OF OP UNITS. Our operating partnership is
managed and operated by its general partner. Unlike the holders of common stock
in a corporation, holders of OP Units have only limited voting rights on matters
affecting our operating partnership's business. Holders of OP Units have no
right to elect the general partner on an annual or other continuing basis, and
the general partner may not be removed by holders of OP Units. As a result,
holders of OP Units have limited influence on matters affecting the operation of
our operating partnership and third parties may find it difficult to attempt to
gain control or influence the activities of our operating partnership.
    
 
                                       S-9
<PAGE>   14
 
   
     DILUTION OF INTERESTS OF HOLDERS OF OP UNITS. We may issue an unlimited
number of additional OP Units or other securities for such consideration and on
such terms as we may establish, without the approval of the holders of OP Units.
Such securities could have priority over the OP Units as to cash flow,
distributions and liquidation proceeds. The effect of any such issuance may be
to dilute the interests of holders of OP Units.
    
 
   
     POSSIBLE INCREASE IN CONTROL BY THE COMPANY. As a result of the offer, we
may increase our ability to influence voting decisions with respect to your
partnership. Also, removal of your general partner or the property manager of
your partnership's property may become more difficult or impossible without our
consent or approval.
    
 
   
     GENERAL RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES. The selective
acquisition, development and expansion of apartment properties is one component
of our growth strategy. However, we can make no assurance as to our ability to
complete future acquisitions. Although we seek acquisitions and development
activities that are accretive on a per share basis, acquisitions and development
activities may fail to perform in accordance with our expectations.
    
 
   
     WE MAY HAVE DIFFICULTY MANAGING OUR RAPID GROWTH. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of AIMCO Properties from 132
properties with 29,296 units to 1,045 properties with 200,911 units. These
acquisitions have included purchases of properties, interests in entities that
own or manage properties and corporate mergers. The proposed Insignia merger
will be our largest acquisition so far. We can provide no assurance that we will
be able to successfully integrate any acquired businesses or properties.
    
 
   
     WE MAY INCUR ADDITIONAL EXPENSES IF THE PROPOSED INSIGNIA MERGER IS
TERMINATED. We are obligated to pay Insignia $50 million in liquidated damages
if the Insignia Merger Agreement is terminated as a result of our breach of
certain representations, warranties or covenants, or our failure to satisfy
certain conditions to closing. Also, if the Insignia Merger Agreement is
terminated due to a breach by us, certain Insignia executives have the right to
require us to purchase certain of their shares of Insignia common stock.
    
 
   
     LITIGATION ASSOCIATED WITH PARTNERSHIP ACQUISITIONS. We have engaged in,
and intend to continue to engage in, the selective acquisition of interests in
limited partnerships that own apartment properties. In some cases, we have
acquired the general partner of a partnership and then made an offer to acquire
the limited partners' interests in the partnership. In these transactions, we
are sometimes subject to litigation based on claims that the general partner has
breached its fiduciary duties to its limited partners or that the transaction
violates the relevant partnership agreement.
    
 
   
     RISKS ASSOCIATED WITH DEBT FINANCING. Our organizational documents do not
limit the amount of debt that we may incur, and we have significant amounts of
debt outstanding. Payments of principal and interest may leave us with
insufficient cash resources to operate our properties or pay distributions
required to be paid in order to maintain our qualification as a REIT. We are
also subject to the risk that our cash flow from operations will be insufficient
to make required payments of principal and interest, and the risk that existing
indebtedness may not be refinanced or that the terms of any refinancing will not
be as favorable as the terms of existing indebtedness. If we fail to make
required payments of principal and interest on any debt, our lenders could
foreclose on the properties securing such debt with a consequent loss of income
and asset value to us.
    
 
   
     INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE. As of June
30, 1998, approximately $182 million of our debt was subject to variable
interest rates. An increase in interest rates could increase our interest
expense and adversely affect our cash flow.
    
 
   
     RISKS OF INTEREST RATE HEDGING ARRANGEMENTS. From time to time, in
anticipation of refinancing debt, we enter into agreements to reduce the risks
associated with increases in short-term interest rates. Although these
agreements provide us with some protection against rising interest rates, these
agreements also reduce the benefits to us when interest rates decline.
    
 
   
     COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR
INVESTORS. Some of our debt and other securities contain covenants that restrict
our ability to make distributions or other payments to our
    
 
                                      S-10
<PAGE>   15
 
   
investors unless certain financial tests or other criteria are satisfied. In
some cases, our subsidiaries are subject to similar provisions, which may
restrict their ability to make distributions to us.
    
 
   
     WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES. All of
our properties are owned, and all of our operations are conducted, by the AIMCO
Operating Partnership and our other subsidiaries. As a result, we depend on
distributions and other payments from the AIMCO Operating Partnership and other
subsidiaries in order to satisfy our financial obligations and make payments to
our investors. The ability of the AIMCO Operating Partnership and other
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations.
    
 
   
     REAL ESTATE INVESTMENT RISKS. Our ability to make payments to our investors
depends on our ability to generate funds from operations in excess of required
debt payments and capital expenditure requirements. Funds from operations and
the value of our properties may be adversely affected by events or conditions
which are beyond our control, including local conditions that might adversely
affect apartment occupancy or rental rates, increases in operating costs, and
changes in governmental regulations and the related costs of compliance.
    
 
   
     POSSIBLE ENVIRONMENTAL LIABILITIES. Various Federal, state and local laws
subject property owners or operators to liability for the costs of removal or
remediation of certain hazardous substances released on a property. Such laws
often impose liability without regard to whether the owner or operator knew of,
or was responsible for, the release of the hazardous substances. The presence
of, or the failure to properly remediate, hazardous substances may adversely
affect occupancy at contaminated apartment communities and our ability to sell
or borrow against contaminated properties. In addition to the costs associated
with investigation and remediation actions brought by governmental agencies, the
presence of hazardous wastes on a property could result in personal injury or
similar claims by private plaintiffs.
    
 
   
     LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED
EXPENSES. Under the Americans with Disabilities Act of 1990, all places of
public accommodation are required to meet certain Federal requirements related
to access and use by disabled persons. Although we believe that our properties
are substantially in compliance with present requirements, we may incur
unanticipated expenses to comply with them.
    
 
   
     RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING. As of June 30, 1998,
our portfolio included 375 Owned Properties, 96 Equity Properties, and 81
Managed Properties that benefit from governmental programs intended to provide
housing to people with low or moderate incomes. As a condition to the receipt of
assistance under these programs, the properties must comply with various
requirements, which typically limit rents to pre-approved amounts. If permitted
rents on a property are insufficient to cover costs, a sale of the property may
become necessary, which could result in a loss of management fee revenue. We can
make no assurance that we will always receive the governmental approvals
required to own or manage these types of properties.
    
 
   
     THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES. We
manage some properties owned by third parties. We may suffer a loss of revenue
if we lose our right to manage these properties or if the rental revenues upon
which our management fees are based decline.
    
 
   
     DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS. Although we have entered into
employment agreements with each of Terry Considine, Peter K. Kompaniez and
Steven D. Ira, the loss of any of their services could have an adverse effect on
our operations.
    
 
   
     ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT. If we fail to qualify
as a REIT, we would not be allowed a deduction for distributions to stockholders
in computing our taxable income and we would be subject to Federal income tax at
regular corporate rates. In addition, unless we are entitled to relief under the
tax law, we could not elect to be taxed as a REIT for four years following the
year during which we were disqualified. Therefore, if we lose our REIT status,
the funds available for payment to our investors would be reduced substantially
for each of the years involved.
    
 
                                      S-11
<PAGE>   16
 
   
     EFFECT OF REIT DISTRIBUTION REQUIREMENTS. As a REIT, we are subject to
annual distribution requirements, which limit the amount of cash we have
available for other business purposes, including amounts to fund our growth.
    
 
   
     POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the Federal laws and interpretations thereof could adversely affect our
investors.
    
 
   
     POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES. Our charter
limits ownership of our common stock by any single shareholder to 8.7% of the
outstanding shares (or 15% in the case of certain pension trusts, registered
investment companies and Mr. Considine). Our charter also prohibits anyone from
buying shares if the purchase would result in us losing our REIT status. If you
or anyone else acquires shares in excess of the ownership limit or in violation
of the ownership requirements of the Internal Revenue Code for REITs, the
transfer will be considered null and void.
    
 
   
     OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO
ACQUIRE CONTROL OF THE COMPANY. The 8.7% ownership limit discussed above may
have the effect of precluding acquisition of control of us by a third party
without the consent of our Board of Directors. Our charter authorizes our Board
of Directors to issue up to 510,750,000 shares of capital stock. Under the
charter, our Board of Directors has the authority to classify and reclassify any
of our unissued shares of capital stock into shares of preferred stock with such
preferences, rights, powers and restrictions as the Board of Directors may
determine. The authorization and issuance of preferred stock could have the
effect of delaying or preventing someone from taking control of us, even if a
change in control were in our stockholders' best interests. As a Maryland
corporation, we are subject to various Maryland laws which may have the effect
of discouraging offers to acquire us and of increasing the difficulty of
consummating any such offers, even if our acquisition would be in our
stockholders' best interests.
    
 
   
BACKGROUND AND REASONS FOR THE OFFER
    
 
   
  Background of the Offer
    
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. Our offer
provides us with an opportunity to increase our ownership interest in your
partnership's property while providing you and other investors with an
opportunity to liquidate your current investment and to invest in our OP Units
or receive cash, or to retain your units.
    
 
   
     In June, 1997, we acquired the general partner of your partnership. In
1997, we also acquired a 95% non-voting interest in the company that manages the
property owned by your partnership. We conducted two prior tender offers for
units of your partnership. In August, 1997 we acquired a 0.7576% limited
partnership interest in your partnership through the first tender offer. In June
1998, we acquired an additional 0.3788% limited partnership interest in your
partnership through the second tender offer. We currently own a 1.1364% limited
partnership interest in your partnership.
    
 
   
     We contacted Robert A. Stanger & Co., Inc. in August 1998 to discuss the
possibility of Stanger providing an independent fairness opinion for our offer.
We chose Stanger based on Stanger's expertise and strong reputation in this area
of work. On August 28, 1998, we entered into an agreement with Stanger to
provide such a fairness opinion.
    
 
   
  Alternatives Considered
    
 
   
     The following is a brief discussion of the benefits and disadvantages of
alternatives to our offer that could have been pursued by your general partner:
    
 
   
          Liquidation. One alternative to our offer would be for your
     partnership to sell its assets, distribute the net liquidation proceeds to
     its partners in accordance with your partnership agreement, and then
     dissolve. Partners would be at liberty to use the net liquidation proceeds
     after taxes for investment,
    
 
                                      S-12
<PAGE>   17
 
   
     business, personal or other purposes, at their option. If your partnership
     were to sell its assets and liquidate, you and your partners would not need
     to rely upon capitalization of income or other valuation methods to
     estimate the fair market value of your partnership's assets. Instead, such
     assets would be valued through negotiations with prospective purchasers.
     However, a liquidating sale of your partnership's property would be a
     taxable event for you and your partners and could result in significant
     amounts of taxable income to you and your partners. Under your partnership
     agreement, a sale of your partnership's assets and the subsequent
     liquidation of your partnership could occur only with the consent of at
     least a majority of the partners in your partnership. In the absence of
     such consent, your only option for liquidation of your investment would be
     to sell your units in a private transaction. Any such sale could be at a
     very substantial discount from your pro rata share of the fair market value
     of your partnership property and might involve significant expense and
     delay.
    
 
   
        Continuation of Your Partnership Without the Offer. A second alternative
     would be for your partnership to continue its business without our offer. A
     number of advantages would result from the continued operation of your
     partnership. Given improving rental market conditions, the level of
     distributions might increase over time. We believe it is possible that the
     private resale market for apartment and retail properties could improve
     over time, making a sale of your partnership's property in a private
     transaction at some point in the future a more viable option than it is
     currently. However, there are several risks and disadvantages that result
     from continuing the operations of your partnership without the offer. Your
     partnership has required funding from its partners. Continuation of your
     partnership's operations is dependent on additional funding from partners
     or from other sources. Your partnership faces maturity or balloon payment
     dates on its mortgage loans and must either obtain refinancing or sell its
     property. If your partnership were to continue operating as presently
     structured, it could be forced to borrow on terms that could result in net
     losses from operations. In addition, continuation of your partnership
     without the offer would deny you and your partners the benefits that your
     general partner expects to result from the offer. For example, a partner of
     your partnership would have no opportunity for liquidity unless he were to
     sell his units in a private transaction. Any such sale would likely be at a
     very substantial discount from the partner's pro rata share of the fair
     market value of your partnership's property.
    
 
   
  Expected Benefits of the Offer
    
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by your partnership. The offer
provides us with an opportunity to increase our ownership interest in your
partnership property while providing you and other investors with an opportunity
to retain or liquidate your investment in your partnership for cash or for units
in the AIMCO Operating Partnership.
    
 
   
     There are four principal advantages of exchanging your units for
Tax-Deferral      % Preferred OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral      % Preferred OP Units. Upon redemption, we
       will give you, at our option, shares of AIMCO's Class I Preferred Stock,
       shares of AIMCO's Class A Common Stock or cash. AIMCO's Class A Common
       Stock is, and AIMCO's Class I Preferred Stock is expected to be, listed
       and traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral      % Preferred OP
       Units.
    
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Tax-Deferral      % Preferred OP
       Units before any distributions are paid to holders of Tax-Deferral Common
       OP Units. Your partnership has not paid any distributions on your units
       since the inception of your partnership.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
    
 
                                      S-13
<PAGE>   18
 
   
     There are five principal advantages of exchanging your units for
Tax-Deferral Common OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Tax-Deferral Common OP Units. Upon redemption, we will give
       you, at our option, shares of AIMCO's Class A Common Stock (on a
       one-for-one basis, subject to adjustment in certain circumstances) or an
       equivalent amount of cash. AIMCO's Class A Common Stock is listed and
       traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you exchange your units solely for Tax-Deferral Common OP Units.
    
 
   
     - Quarterly Distributions. We pay quarterly distributions on the
       Tax-Deferral Common OP Units. For the quarter ended June 30, 1998, we
       paid distributions of $0.5625 on each of the Tax-Deferral Common OP Units
       (equivalent to $2.25 on an annual basis). Your partnership has not paid
       any distributions on your units since the inception of your partnership.
    
 
   
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to your partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
    
 
   
     The principal advantage if you tender your units for cash is immediate
liquidity. However, tendering your units for cash may cause you to recognize
taxable gain for federal income tax purposes.
    
 
   
     For a description of certain disadvantages of the offer, see "Risk
Factors."
    
 
   
TERMS OF THE OFFER
    
 
   
     General. We are offering to acquire up to        % of the outstanding units
of your partnership for consideration per unit of        Tax-Deferral      %
Preferred OP Units,        Tax-Deferral Common OP Units, or $       in cash. If
you tender units pursuant to the offer, you may chose to receive any of such
forms of consideration for your units or any combination of such forms of
consideration. The offer is made upon the terms and subject to the conditions
set forth in this Prospectus Supplement, the accompanying Prospectus and the

commence on               , 1998 and will be deemed to be made as of
            , 1998. Any tender of units pursuant to the offer will be effective
as of             , 1998. The effective date will not affect the amount of
distributions received by tendering Offerees.
    
 
   
     Expiration Date. Our offer will expire at 5:00 P.M., Denver, Colorado time,
on               , 1998, unless extended.
    
 
   
     Conditions of the Offer. Our offer is not conditioned on the tender of any
minimum number of units. However, our offer is conditioned on a number of other
factors.
    
 
   
     Procedures for Tendering. If you desire to accept our offer, you must
complete and sign the Letter of Transmittal in accordance with the instructions
contained therein and forward or hand deliver it, together with any other
required documents, to the Information Agent, either with your units to be
tendered or in compliance with the specified procedures for guaranteed delivery

     Proration. If the number of units properly tendered and not withdrawn prior
to the Expiration Date exceeds        % of the outstanding units, upon the terms
and subject to the conditions of the offer, we will accept units in the
following order of priority: (1) all units properly tendered and not withdrawn
prior to the Expiration Date by any person holding one or fewer units who
tenders all of his or her units; and (2) after purchase of such units, all other
units properly tendered and not withdrawn prior to the Expiration Date on a pro
rata basis, with adjustments to avoid resulting ownership of less than one unit

expiration date or any renewal of the offer.

you and your partners with an opportunity to liquidate your current investment
and to invest in our operating partnership or receive cash, or to retain your
units.

sole discretion, at any time and from time to time, to:

       acceptance of, or payment for, any units not already accepted for payment
       or paid for; and
    
 
   
     - to amend the offer in any respect.
    
 
   
     Effects of the Offer. As a result of the offer, we, in our capacity as a
limited partner of your partnership, will participate in any subsequent
distributions to limited partners, to the extent of units we purchase pursuant
to the offer. The offer will not affect the operation of your partnership's
property because your general partner and the property manager of your
partnership's property will remain unchanged.
    
 
   
     Voting by the AIMCO Operating Partnership. If we acquire a substantial
amount of units pursuant to the offer, we may be in a position to influence
voting decisions with respect to your partnership.
    
 
   
     Future Plans for Your Partnership. We currently intend that, upon
consummation of the offer, your partnership will continue its business and
operations substantially as they are currently being conducted. We do not have
any present plans or proposals which relate to or would result in any material
changes in your partnership's structure or business. We have no present
intention to cause your partnership to sell its property or to prepay the
current mortgage within any specified time period.
    
 
   
     Certain Legal Matters. Except as set forth in this section, we are not,
based on information provided by your general partner, aware of any licenses or
regulatory permits that would be material to the business of your partnership,
and that might be adversely affected by our acquisition of units as contemplated
herein. On the same basis, we are not aware of any filings, approvals or other
actions by or with any domestic or foreign governmental authority or
administrative or regulatory agency that would be required prior to our
acquisition of units pursuant to the offer as contemplated herein that have not
been made or obtained. We are not aware
    
 
                                      S-15
<PAGE>   20
 
   
of any jurisdiction in which the making of the offer is not in compliance with
applicable law. If we become aware of any jurisdiction in which the making of
the offer would not be in compliance with applicable law, we will make a good
faith effort to comply with any such law.
    
 
   
     Fees and Expenses. Except as set forth in this section, we will not pay any
fees or commissions to any broker, dealer or other person for soliciting tenders
of units pursuant to the offer. We will pay the Information Agent reasonable and
customary compensation for its services in connection with the offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Information
Agent against certain liabilities and expenses in connection therewith,
including liabilities under the federal securities laws. We will also pay all
costs and expenses of printing and mailing this Prospectus Supplement and the
legal fees and expenses in connection therewith. We will also pay the fees of
Stanger for providing the fairness opinions for the offer. We estimate that our
total costs and expenses in making the offer (excluding the purchase price of
the units payable to you and your partners) will be approximately
$               .
    
 
   
     Accounting Treatment. Upon consummation of the offer, we will account for
our investment in any acquired units under the purchase method of accounting.
There will be no effect on the accounting treatment of your partnership as a
result of the offer.
    
 
   
DESCRIPTION OF TAX-DEFERRAL   % PREFERRED OP UNITS
    
 
   
     Tax-Deferral   % Preferred OP Units are a class of Partnership Preferred
Units of our operating partnership. Tax-Deferral   % Preferred OP Units are not
listed on any national securities exchange or quoted on the NASDAQ System, there
is no active trading market for Tax-Deferral      % Preferred OP Units and none
is likely to develop because they are subject to restrictions on transfer. For a
detailed description of the distribution, liquidation, redemption, voting and
other rights and restrictions applicable to Tax-Deferral   % Preferred OP Units,
see "Description of Preferred OP Units."
    
 
   
DESCRIPTION OF CLASS I PREFERRED STOCK
    
 
   
     The Class I Preferred Stock, which holders of Preferred OP Units may
receive upon redemption of their Tax-Deferral   % Preferred OP Units, is a
series of preferred stock of AIMCO which is expected to be listed on the New
York Stock Exchange under the symbol "AIVPrI." For a detailed description of the
dividend, liquidation, redemption, voting and other rights and restrictions
applicable to Class I Preferred Stock, see "Description of Class I Preferred
Stock."
    
 
   
COMPARISON OF TAX-DEFERRAL   % PREFERRED OP UNITS AND CLASS I PREFERRED STOCK
    
 
   
     There are a number of significant differences between Tax-Deferral      %
Preferred OP Units and Class I Preferred Stock relating to, among other things,
the nature of the investment, voting rights, distributions and liquidity and
transferability/redemption rights. See "Comparison of Preferred OP Units and
Class I Preferred Stock" for a chart highlighting such differences.
    
 
   
CERTAIN FEDERAL INCOME TAX MATTERS
    
 
   
     You will generally not recognize any immediate taxable gain or loss for
federal income tax purposes if you exchange your units solely for Tax-Deferral
     % Preferred OP Units or Tax-Deferral Common OP Units. You will recognize a
gain or loss for federal income tax purposes on units you sell for cash. The
exchange of your units for our OP Units and cash will be treated, for Federal
income tax purposes, as a partial sale of such units and as a partial tax-free
contribution of such units to our operating partnership.
    
 
   
     THIS SUMMARY IS A GENERAL DISCUSSION OF CERTAIN OF THE ANTICIPATED FEDERAL
INCOME TAX CONSEQUENCES OF TENDERING UNITS IN THE OFFER. THIS SUMMARY DOES NOT
DISCUSS ALL ASPECTS OF FEDERAL INCOME TAXATION THAT MAY BE RELEVANT TO YOU IN
LIGHT OF YOUR SPECIFIC CIRCUMSTANCES OR IF YOU ARE SUBJECT TO SPECIAL TREATMENT
UNDER THE FEDERAL INCOME TAX LAWS. THE PARTICULAR TAX CONSEQUENCES OF THE OFFER
TO YOU WILL DEPEND ON A NUMBER OF FACTORS RELATED TO YOUR TAX SITUATION. YOU
SHOULD REVIEW "CERTAIN FEDERAL INCOME TAX MATTERS" STARTING ON

VALUATION OF UNITS
    
 
   
     We determined the offer price by estimating the proceeds that you would
receive if your partnership were liquidated. For this purpose, we estimated the
value of the property owned by your partnership using the direct capitalization
method. This method involves applying a capitalization rate to your
partnership's annual forecasted net operating income. However, there are a
number of available methods to value real estate, each of which requires
judgments about certain variables. We used our best judgment for these
variables, but our valuation is ultimately an estimate. The proceeds that you
would receive if you sold your units to someone else or if your partnership were
actually liquidated might be higher or lower than our offer price. We determined
our offer price as follows:

FAIRNESS OF THE OFFER
    
 
   
     Fairness to Offerees. We own your general partner. As a result, your
general partner has a conflict of interest and makes no recommendation to you as
to whether you should tender or refrain from tendering your units. We have
retained Stanger to conduct an analysis of the offer and to render an opinion as
to the fairness to you of our offer price. Stanger is not affiliated with us or
your general partner. Stanger is one of the leaders in the field of analyzing
and evaluating complex real estate transactions. However, we provided much of
the information used by Stanger in forming its fairness opinion. We believe the
information provided to Stanger is accurate in all material respects. See
"Stanger Analysis." No person has been authorized to make any recommendation on
behalf of your general partner with respect to the offer. You must make your own
decision whether to tender based upon a number of factors, including your own
financial needs, other financial opportunities and tax position.
    
 
                                      S-17
<PAGE>   22
 
   
     The terms of the offer, and in particular the exchange ratios, have been
established by us and are not the result of arms-length negotiations. In
evaluating the fairness of the offer, your general partner considered numerous
factors. See "Fairness of the Offer -- Position of the General Partner of Your
Partnership With Respect to the Offer; Fairness." In evaluating these factors,
your general partner did not quantify or otherwise attach particular weight to
any of them. Your general partner has a conflict of interest with respect to the
offer's completion. See "Conflicts of Interest."
    
 
   
     If you choose not to tender any units, your interest in your partnership
will remain unchanged, except that we will own a larger share of the limited
partnership interests in your partnership than we did before the offer. If we
acquire a substantial number of units pursuant to the offer, we may be in a
position to influence voting decisions with respect to your partnership. Your
general partner has no present intention to liquidate, sell, finance or
refinance your partnership's property within any specified time period.
    
 
   
     Comparison of Consideration to Alternative Consideration. To assist holders
of units in evaluating the offer, the general partner of Your Partnership has
attempted to compare the cash offer price against: (a) the prices at which the
units have been sold in the illiquid secondary market and (b) estimates of the
value of the units on a liquidation basis. The estimated value of your
partnership on a going concern basis could result in proceeds on a per unit
basis which could be higher or lower than the Offer Price. The general partner
of your partnership believes that analyzing the alternatives in terms of
estimated value, established based upon currently available data and, where
appropriate, reasonable assumptions made in good faith, establishes a reasonable
framework for comparing alternatives. Since the value of the consideration for
alternatives to the offer is dependent upon varying market conditions, no
assurance can be given that the estimated values reflect the range of possible
values. See "Valuation of Units."
    
 
   
     The results of these comparative analyses are summarized in the following
chart. Offerees should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of your partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of your partnership; the capitalization
rates that will be used by prospective buyers when your partnership's assets are
liquidated; and appropriate discount rates to apply to expected cash flows in
computing the present value of the cash flows that may be received with respect
to units.

     Allocation of Consideration. AIMCO has allocated the consideration for the
offer to the offerees in accordance with the liquidation provisions of your
partnership agreement. The general partner of your partnership owns a 5.5% stake
in your partnership, the special limited partners own a 19.5% stake in your
partnership, and the offerees own a 75.0% stake in your partnership according to
your partnership agreement. The offerees have certain liquidation preferences
under your partnership agreement such that the general partner and the special
limited partners will receive liquidation proceeds only if certain performance
thresholds are met. Since such thresholds have not been met, 100% of the
consideration for the offer is being allocated to the offerees. See "Valuation
of Units."
    
 
   
STANGER ANALYSIS
    
 
   
     We engaged Stanger to conduct an analysis of our offer and to render its
opinion based on the review, analysis, scope and limitations described therein,
as to the fairness to you of our offer price, from a financial point of view.

and qualifications

made, matters considered and limitations on the review and analysis, is set
forth in Appendix B-1 and should be read in its entirety. We imposed no
conditions or limitations on the scope of Stanger's investigation or with
respect to the methods and procedures to be followed in arriving at the fairness
opinion. We have agreed to indemnify Stanger against certain liabilities arising
out of its engagement to render the fairness opinion. Based on its analysis, and
subject to the assumptions, limitations and qualifications cited in its opinion,
Stanger concluded that our offer price is fair to you, from a financial point of
view.
    
 
   
COMPARISON OF YOUR PARTNERSHIP AND OUR OPERATING PARTNERSHIP
    
 
   
     There are a number of significant differences between your partnership and
our operating partnership relating to, among other things, form of organization,
permitted investments, policies and restrictions, management structure,
compensation and fees, and investor rights. See "Comparison of Your Partnership
and the AIMCO Operating Partnership" for a chart highlighting such differences.
    
 
   
COMPARISON OF YOUR UNITS AND AIMCO OP UNITS
    
 
   
     There are a number of significant differences between your units,
Tax-Deferral      % Preferred OP Units and Tax-Deferral Common OP Units relating
to, among other things, the nature of the investment, voting rights,
distributions and liquidity and transferability/redemption. See "Comparison of
Your Units and AIMCO OP Units" for a chart highlighting such differences.
    
 
   
CONFLICTS OF INTEREST
    
 
   
     Conflicts of Interest with Respect to the Offer. Your general partner is
affiliated with us and, therefore, has substantial conflicts of interest with
respect to the offer, including (i) the fact that replacement of your general
partner could result in a decrease or elimination of the management fees paid to
an affiliate for managing your partnership's property and (ii) our desire to
purchase units at a low price and your desire to sell units at a high price.
Your general partner makes no recommendation as to whether you should tender or
refrain from tendering your units.
    
 
   
     Conflicts of Interest that Currently Exist for Your Partnership. We own
both the general partner of your partnership and a 95% non-voting interest in
the manager of your partnership's property, which received management fees of
$427,385 in 1996, $437,571 in 1997 and $215,708 for the first six months of
1998. We have no current intention of changing the fee structure for your
property manager. The general partner of your partnership receives a fee of
$2,083 per month from your partnership.
    
 
   
     Competition Among Properties. Your partnership's property and other
properties owned or managed by us may compete with one another for tenants.
However, in some cases it may be difficult to determine precisely the confines
of the market area for particular properties and some competition may exist.
Furthermore, you should bear in mind that we anticipate acquiring properties in
general market areas where your partnership's property is located. It is
believed that this concentration of properties in a general market area will
facilitate overall operations through collective advertising efforts, staffing
and other operational efficiencies. In managing our properties, we will attempt
to reduce such conflicts between competing properties by referring prospective
tenants to the property considered to be most conveniently located for the
tenants' needs.
    
 
   
     Features Discouraging Potential Takeovers. Certain provisions of our
governing documents, as well as statutory provisions under certain state laws,
could be used by our management to delay, discourage or thwart efforts of third
parties to acquire control of, or a significant equity interest in, us. See
"Comparison of Your Partnership and the AIMCO Operating Partnership."
    
 
   
     Future Exchange Offers. If the results of operations were to improve for
your partnership under our management, we might be required to pay a higher
price for any future exchange offers we may make for units of your partnership.
Although we have no current plans to conduct further exchange offers for your
units, our plans may change based on future circumstances. Any such future
offers that we might make could be for consideration that is more or less than
the consideration we are currently offering.

YOUR PARTNERSHIP
    
 
   
     Your Partnership and its Property. Casa Del Mar Associates Limited
Partnership is a Florida limited partnership which was formed on August 26, 1988
for the purpose of owning and operating an assisted living apartment property
located in Boca Raton, Florida, known as "Casa Del Mar." In October, 1988, it
completed a private placement of units that raised net proceeds of approximately
$7,400,000. Casa Del Mar consists of 214 apartment units. Your partnership has
no employees.
    
 
   
     Property Management. Since July 12, 1996, your partnership's property has
been managed by an affiliate of ours. Pursuant to the management agreement
between the property manager and your partnership, the property manager operates
your partnership property, establishes rental policies and rates and directs
marketing activities. The property manager also is responsible for maintenance,
the purchase of equipment and supplies, and the selection and engagement of all
vendors, suppliers and independent contractors. The property manager is an
affiliate of your general partner and us.
    
 
   
     Investment Objectives and Policies; Sale or Financing of Investments. Under
your partnership agreement, your partnership is permitted to raise new capital
and reinvest cash in new properties. Your partnership will terminate on December
31, 2038, unless earlier dissolved. Your general partner has no present
intention to liquidate, sell, finance or refinance your partnership property
within any specified time period. An investment in your partnership is a finite
life investment in which partners receive regular cash distributions out of your
partnership's distributable cash flow, if any, and upon liquidation.
    
 
   
     Capital Replacement Plans. Your partnership maintains an ongoing program of
capital improvements, replacements and renovations, including roof replacements,
kitchen and bath renovations, balcony repairs (where applicable), replacement of
various building systems and other replacements and renovations in the ordinary
course of business. All capital improvement and renovation costs are expected to
be paid from operating cash flows, cash reserves, or from short-term or
long-term borrowings.
    
 
   
     Borrowing Policies. Your partnership agreement allows your partnership to
incur debt. As of June 30, 1998, your partnership had a current mortgage note
outstanding of $13,800,862, payable to Mellon Bank MD, which bears interest at
the rate of 8.12%. The mortgage debt is due in August 2005. In addition, your
partnership had borrowed $1,714,490 (including accrued interest) from an
unrelated party on an unsecured basis as of June 30, 1998. The majority of these
borrowings bear interest at 9% and are due July 2006. Your partnership agreement
also allows your general partner to lend funds to your partnership. As of June
30, 1998, your general partner had outstanding loans (including accrued and
unpaid interest) of $5,906,796 to your partnership, which generally bear
interest at a rate of 9% and mature in July 2006.
    
 
   
     Competition. There are other residential properties within the market area
of your partnership's property. The number of competitive properties in such an
area could have a material effect on the rental market for the apartments at a
property and the rents that may be charged for such apartments.
    
 
   
     Legal Proceedings. Your partnership is party to a variety of legal
proceedings related to its property ownership arising in the ordinary course of
the business, which are not expected to have a material adverse effect on its
financial condition or results of operations.
    
 
   
     Fiduciary Responsibility of Your General Partner. Under applicable law,
your general partner is accountable to you as a fiduciary. Your partnership
agreement provides that neither your general partner nor any of its affiliates
performing services on behalf of your partnership will be liable to your
partnership or any of its parties for any act or omission by any such person
performed in the good faith belief that such action or omission was in the best
interests of your partnership as long as certain other conditions are met. As a
result, you and your partners might have a more limited right of action in
certain circumstances than you would have in the absence of such a provision in
your partnership agreement.
    
 
   
     Your partnership agreement also provides that your general partner and
certain related parties are indemnified from losses relating to acts performed
or failures to act in connection with the business of your partnership (except
to the extent indemnification is prohibited by law) as long as certain
conditions are met.

     Distributions by Your Partnership. Your partnership has not made any
distributions in the past and is not projected to make any distributions in
1998.
    
 
   
     Allocations of Income. Your partnership has generally been allocating tax
losses in the past and is projected to do so in 1998.
    
 
   
     Transfers. Your units are not listed on any national securities exchange or
quoted on the NASDAQ System, and there is no established public trading market
for the units. Secondary sales activity for the units has been limited and
sporadic. Your general partner monitors transfers of the units (a) because the
admission of the transferee as a substitute limited partner in your partnership
requires the consent of your general partner under your partnership agreement,
and (b) in order to track compliance with safe harbor provisions to avoid
treatment as a "publicly traded partnership" for tax purposes. However, your
general partner does not monitor or regularly receive or maintain information
regarding the prices at which secondary sale transactions in the units have been
effectuated.
    
 
   
     Compensation and Distributions to Your General Partner and Its
Affiliates. See "Your Partnership -- Compensation and Distributions to General
Partner and Affiliates" for a table detailing such compensation and
distributions.
    
 
   
SOURCE AND AMOUNT OF FUNDS AND TRANSACTIONAL EXPENSES
    
 
   
     We expect that approximately $               will be required to purchase
all of the units sought in our offer, if such units are tendered for cash. We
will obtain all such funds from cash from operations, equity issuances and short
term borrowings.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of AIMCO Class A Common Stock and issued 966,000 shares of
     convertible preferred stock and 513,514 unregistered shares of AIMCO Common
     Stock. The proceeds from the offering and such other issuances were
     contributed by AIMCO to AIMCO Properties, L.P. for 9,075,000 OP Units,
     966,000 Preferred Units and 513,514 OP Units, respectively. On such date,
     AIMCO Properties, L.P. and its predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     AIMCO Properties, L.P. to continue and expand the property management and
     related businesses of its predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of AIMCO Class A Common Stock that were
     issued concurrently with the initial public offering were repurchased in
     1995.
    
 
   
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO Properties, L.P.
    
 
   
(c)  Represents AIMCO Properties, L.P.'s share of earnings from partnerships
     that own 83,431 apartment units in which partnerships AIMCO Properties,
     L.P. purchased an equity interest from the NHP Real Estate Companies.
    
 
   
(d)  Represents AIMCO Properties, L.P. equity earnings in unconsolidated
     subsidiaries.
    
 
   
(e)  AIMCO Properties, L.P.'s management believes that the presentation of FFO,
     when considered with the financial data determined in accordance with GAAP,
     provides a useful measure of performance. However, FFO does not represent
     cash flow and is not necessarily indicative of cash flow or liquidity
     available to AIMCO Properties, L.P., nor should it be considered as an
     alternative to net income as an indicator of operating performance. The
     Board of Governors of NAREIT defines FFO as net income (loss), computed in
     accordance with GAAP, excluding gains and losses from debt restructuring
     and sales of property, plus real estate related depreciation and
     amortization (excluding amortization of financing costs), and after
     adjustments for unconsolidated partnerships and joint ventures. AIMCO
     Properties, L.P. calculates FFO consistent with the NAREIT definition, plus
     amortization of management company goodwill, the non-cash deferred portion
     of the income tax provision for unconsolidated subsidiaries and less the
     payments of dividends on perpetual preferred stock. AIMCO Properties, L.P.
     management believes that presentation of FFO provides investors with
     industry-accepted measurements which help facilitate an understanding of
     its ability to make required dividend payments, capital expenditures and
     principal payments on its debt. There can be no assurance that AIMCO
     Properties, L.P.'s basis of computing FFO is comparable with that of other
     REITs.
    
 
   
     The following is a reconciliation of net income to FFO:

(a)  The unaudited Pro Forma Financial Information has been prepared under the
     assumption that the AIMCO stockholders approved the Insignia merger, and
     that only shares of AIMCO Class E Preferred Stock were issued.
    
 
   
(b)  Pro forma cash provided by operating activities represents net income, plus
     depreciation and amortization less the non-cash portion of AIMCO Properties
     L.P.'s equity in earnings of unconsolidated subsidiaries. The pro forma
     amounts do not include adjustments for changes in working capital resulting
     from changes in current assets and current liabilities as there is no
     historical data available as of both the beginning and end of each period
     presented.
    
 
   
(c)  On a pro forma basis, cash used in investing activities represents the
     minimum annual provision for capital replacements of $300 per owned
     apartment unit.
    
 
   
(d)  Pro forma cash used in financing activities represents (i) estimated
     distributions to be paid based on AIMCO Properties, L.P.'s historical
     distribution rate of $1.125 per OP Unit for the six months ended June 30,
     1998 and $1.85 per OP Unit for the year ended December 31, 1997, on
     outstanding OP Units, (ii) estimated distributions to be paid based on the
     rate of $3.5625 per unit for the six months ended June 30, 1998 and $7.125
     per unit for the year ended December 31, 1997 on outstanding Class B
     Partnership Preferred Units, (iii) estimated distributions to be paid based
     on the rate of $1.125 per unit for the six months ended June 30, 1998 and
     $2.25 per unit for the year ended December 31, 1997 on outstanding Class C
     Partnership Preferred Units, (iv) estimated distributions to be paid based
     on the rate of $1.095 per unit for the six months ended June 30, 1998 and
     $2.19 per unit for the year ended December 31, 1997 on outstanding Class D
     Partnership Preferred Units, (v) estimated distributions to be paid based
     on the rate of $1.1718 per unit for the six months ended June 30, 1998 and
     $2.34375 per unit for the year ended December 31, 1997 on outstanding Class
     G Partnership Preferred Units, and (vi) estimated distributions to be paid
     based on the rate of $1.1875 per unit for the six months ended June 30,
     1998 and $2.375 per unit for the year ended December 31, 1997 on
     outstanding Class H Partnership Preferred Units.
    
 
   
(e)  AIMCO Properties, L.P.'s management believes that the presentation of FFO,
     when considered with the financial data determined in accordance with GAAP,
     provides useful measures of AIMCO Properties, L.P. performance. However,
     FFO does not represent cash flow and is not necessarily indicative of cash
     flow or liquidity available to AIMCO Properties, L.P., nor should it be
     considered as an alternative to net income as an indicator of operating
     performance. The Board of Governors of NAREIT defines FFO as net income
     (loss), computed in accordance with GAAP, excluding gains and losses from
     debt restructuring and sales of property, plus real estate related
     depreciation and amortization (excluding

     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO Properties, L.P. calculates FFO in a
     manner consistent with the NAREIT definition, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payments of
     dividends on perpetual preferred stock. AIMCO Properties, L.P. management
     believes that presentation of FFO provides investors with an industry
     accepted measurement which helps facilitate an understanding of AIMCO
     Properties, L.P.'s ability to make required dividend payments, capital
     expenditures and principal payments on its debt. There can be no assurance
     that AIMCO Properties, L.P.'s basis of computing FFO is comparable with
     that of other REITs.
    
 
   
     The following is a reconciliation of pro forma net income to pro forma FFO:

                        THE AIMCO OPERATING PARTNERSHIP
    
 
   
     The AIMCO Operating Partnership conducts substantially all of the
operations of AIMCO (together with the AIMCO Operating Partnership, their
consolidated subsidiaries and their majority-owned subsidiaries, the "Company").
AIMCO is a real estate investment trust that owns and manages multifamily
apartment properties throughout the United States. AIMCO is one of the largest
owners and managers of multifamily apartment properties in the United States
based on apartment unit data compiled by the National Multi Housing Council as
of January 1, 1998. As of June 30, 1998 the Company owned or managed 200,911
apartment units in 1,045 properties located in 42 states, the District of
Columbia and Puerto Rico. As of June 30, 1998, the Company owned or controlled
58,345 units in 210 apartment properties, held an equity interest in 74,318
units in 478 apartment properties and managed 68,248 units in 357 apartment
properties for third party owners and affiliates.
    
 
   
     In August, 1997 we acquired 0.7576% interest in Your Partnership through a
prior tender offer. In June 1998, we acquired an additional 0.3788% interest in
Your Partnership through another tender offer. Other than the Units owned as a
result of these prior tender offers, neither the AIMCO Operating Partnership,
nor, to the best of its knowledge, any of its affiliates, (i) beneficially own
or have a right to acquire any Units, (ii) have effected any transaction in the
Units, or (iii) have any contract, arrangement, understanding or relationship
with any other person with respect to any securities of Your Partnership,
including, but not limited to, contracts, arrangements, understandings or
relationships concerning transfer or voting thereof, joint ventures, loan or
option arrangements, puts or calls, guarantees of loans, guarantees against loss
or the giving or withholding of proxies.
    
 
   
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
    
 
   
                                  RISK FACTORS
    
 
   
RISKS TO OFFEREES WHO TENDER THEIR UNITS IN THE OFFER
    
 
   
     NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION AND NO
GENERAL PARTNER RECOMMENDATION. We did not base the valuation of the Partnership
Property on any third-party appraisal or valuation. We established the terms of
the Offer, including the exchange ratios and the cash consideration. Such terms
are not the result of arms-length negotiations between Your Partnership and us.
It is uncertain whether the Offer Price reflects the value which would be
realized upon sale of the Units or liquidation of Your Partnership's assets.
Because of our affiliation with the general partner of Your Partnership, the
general partner of Your Partnership makes no recommendation to you as to whether
to tender your Units. However, the general partner of Your Partnership believes
that the terms of the Offer, including the Offer Price, are fair to you. We have
retained Stanger to conduct an analysis of our Offer and to render an opinion to
AIMCO as to the fairness to you of the Offer Price, from a financial point of
view.
    
 
   
     OFFER PRICE MAY NOT REPRESENT FUTURE LIQUIDATION VALUE. Your Partnership
Property may outperform our larger, more diversified portfolio of assets.
Although we cannot predict the future value of the Partnership Property, the
Offer Price could be less, perhaps substantially less than the net proceeds that
you would realize upon a future liquidation of Your Partnership. Accordingly,
although there can be no assurance, you might receive more consideration if you
do not tender your Units and, instead, continue to hold such Units and
ultimately receive proceeds from a liquidation of Your Partnership. However, you
may prefer to receive the Offer Price now rather than wait for uncertain future
net liquidation proceeds. Furthermore, the general partner of Your Partnership
has no present intention to liquidate Your Partnership, and Your Partnership
Agreement does not require sale of Your Partnership Property by any particular
date.
    
 
   
     ATTRACTIVE INVESTMENT FOR THE AIMCO OPERATING PARTNERSHIP. We are making
the Offer with a view to making a profit. Accordingly, there is a conflict
between our desire to purchase Units at a low price and your desire to sell your
Units at a high price.

     CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. The general partner of
Your Partnership is a subsidiary of AIMCO and an affiliate of the AIMCO
Operating Partnership and, therefore, has substantial conflicts of interest with
respect to the Offer. These conflicts include the fact that a decision of the
limited partners of Your Partnership to remove, for any reason, the general
partner of Your Partnership or the Property Manager from its current position
would result in a decrease or elimination of the substantial fees paid to the
general partner or the Property Manager for services provided to Your
Partnership. The general partner of Your Partnership makes no recommendation to
you as to whether to tender your Units. Such conflicts of interest in connection
with the Offer and the operation of the Company differ from those conflicts of
interest that currently exist for Your Partnership.
    
 
   
     LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP. Offerees who tender
their Units in accordance with the terms of the Offer transfer all right, title
and interest in and to all Units that are tendered and all distributions in
respect of such Units on or after the date on which we accept such Units for
purchase. Accordingly, following the purchase of your Units, we would be
entitled to receive any future distributions from the operations of Your
Partnership to the extent of the Units we acquire in the Offer. Similarly,
Offerees who tender their Units for OP Units will be entitled to future
distributions from the operations of the AIMCO Operating Partnership.
    
 
   
     TAX RISKS ASSOCIATED WITH THE OFFER. In general, the exchange of Units for
OP Units will not be a taxable transaction. The sale of Units for cash will be a
taxable sale, with the result that you will recognize gain or loss measured by
the difference between the amount realized on the tender and your adjusted tax
basis in the Units you transfer to us. The exchange of Units for OP Units and
cash will be treated, for Federal income tax purposes, as a partial taxable sale
of such Units and as a partial tax-free contribution of such Units to the AIMCO
Operating Partnership. If you exchange your Units for cash or for OP Units and
cash, the "amount realized" will be measured by the sum of the cash received
plus the portion of Your Partnership's liabilities allocated to the Units sold
for federal income tax purposes. To the extent that the amount of cash received
plus the allocable share of Your Partnership's liabilities exceeds your tax
basis for the Units sold, you will recognize gain. Consequently, the tax
liability resulting from such gain could exceed the amount of cash received upon
such sale. Although we have no present intention to liquidate or sell the
Partnership Property or prepay the current mortgage on the Partnership Property
within any specified time period, any such action in the future generally will
require you to fully recognize any deferred taxable gain if you tender for OP
Units. In addition, if the AIMCO Operating Partnership were to be treated as a
"publicly traded partnership" for Federal income tax purposes, passive activity
losses generated by other passive activity investments held by an Offeree,
including passive activity loss carryovers attributable to a Unit, could not be
used to offset such Offeree's allocable share of income generated by the AIMCO
Operating Partnership. See "Certain Federal Income Tax Matters." The conversion
after the one-year holding period of OP Units for shares of Class A Common Stock
or Preferred Stock will be a taxable transaction, with the result that you will
recognize gain or loss measured by the difference between the amount realized on
the tender and your adjusted tax basis in the OP Units exchanged. In addition,
if you become a shareholder in AIMCO after the one-year holding period, you will
no longer be able to use income and loss from their investment to offset
"passive" income and loss from other investments, and the distributions from
AIMCO will constitute taxable income to the extent of AIMCO's earnings and
profits.
    
 
   
     The particular tax consequences of the tender for you will depend upon a
number of factors related to your tax situation, including your tax basis in
your Units, whether you dispose of all of your Units in Your Partnership (and
therefore are no longer subject to the "passive" loss rules with respect to Your
Partnership). Because the income tax consequences of an tender of Units will not
be the same for all Offerees, you should consult your own tax advisor with
specific reference to your own tax situation.
    
 
   
RISKS TO OFFEREES EXCHANGING UNITS FOR OP UNITS IN THE OFFER
    
 
   
     FUNDAMENTAL CHANGE IN NATURE AND TERM OF INVESTMENT. If you tender your
Units for OP Units, you will have changed fundamentally the nature of your
investment. If you tender for OP Units, you will tender an interest in Your
Partnership, which owns and manages a single property or small number of
properties, for interests in the AIMCO Operating Partnership, which is in the
business of acquiring, marketing, managing
    
 
                                      S-29
<PAGE>   34
 
   
     and operating a large portfolio of real properties. While diversification
of assets may reduce certain risks of investment attributable to a single
property or entity, there can be no assurance as to the value or performance of
our securities or our portfolio of properties as compared to the value of your
Units or the specific property of Your Partnership. Proceeds of future asset
sales or refinancings by the AIMCO Operating Partnership generally will be
reinvested rather than distributed.
    
 
   
     UNCERTAINTY OF PUBLIC TRADING MARKET. Recently, there have been declines in
the trading prices for many REIT securities. There may be subsequent changes in
public market valuations of real estate assets relative to private market
valuations of real estate assets. We cannot predict the price at which the Class
I Preferred Stock or the Class A Common Stock will trade following the time at
which Preferred OP Units or Common OP Units may be redeemed for shares of Class
I Preferred Stock or Class A Common Stock. Furthermore, the liquidity of the
Class I Preferred Stock and the Class A Common Stock at the time at which OP
Units may be redeemed is also uncertain.
    
 
   
     COMPANY AUTHORITY. Under our organizational documents, we have the ability
to change our investment, acquisition and financing policies without a vote of
the limited partners of the AIMCO Operating Partnership or the stockholders of
AIMCO. If you tender your Units for OP Units, you will have less effective power
in influencing our policies than you currently have in influencing the policies
of Your Partnership.
    
 
   
     RISKS ASSOCIATED WITH AN INVESTMENT IN AIMCO. We face real estate
investment, financing, management, acquisition and development risks, many of
which are similar to the risks currently faced by Your Partnership, as well as
additional risks. See "Risk Factors" in the accompanying Prospectus.
    
 
   
RISKS TO OFFEREES WHO DO NOT TENDER THEIR UNITS IN THE OFFER
    
 
   
     LACK OF TRADING MARKET FOR UNITS. There is no established or regular
trading market for the Units, nor is there another reliable standard for
determining the fair market value of the Units. If you desire or need liquidity,
you may wish to consider the Offer. The Offer affords you an opportunity to
dispose of your Units for cash, which alternative otherwise might not be
available to you currently or in the foreseeable future. However, the Offer
Price does not necessarily reflect the price that you would receive in an open
market for your Units or upon a liquidation of Your Partnership's assets. Such
prices may be higher or lower than the Offer Price.
    
 
   
     DIFFERENT DISTRIBUTIONS. Based on anticipated annualized distributions of
$     with respect to the Preferred OP Units, current annualized distributions
with respect to the Common OP Units and the estimated 1998 distributions of $0
with respect to the Units, distributions with respect to the Preferred OP Units
and Common OP Units to be received in the Offer are expected to be greater,
immediately following the Offer, than the distributions with respect to Units.
See "Comparison of Ownership of Your Units and AIMCO OP Units -- Distributions."
    
 
   
     FUTURE CONTROL BY THE COMPANY. Because the general partner of Your
Partnership is a subsidiary of AIMCO, we control such general partner and the
management of Your Partnership. In addition, if we acquire Units in the Offer,
we will increase our ability to influence voting decisions with respect to Your
Partnership. Furthermore, in the event that we acquire a substantial number of
Units pursuant to the Offer, removal of the general partner of Your Partnership
by the limited partners (other than us) may become more difficult or impossible.
We also own a 95% non-voting interest in the Property Manager, which manages
Your Partnership Property. In the event that we acquire a substantial number of
Units pursuant to the Offer, removal by the limited partners (other than us) of
the Property Manager may become more difficult or impossible.
    
 
   
     RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR
PARTNERSHIP LIABILITIES. Generally, a decrease in your share of Your Partnership
liabilities is treated, for federal income tax purposes, as a deemed cash
distribution. Although the general partner of Your Partnership has no current
plan or intention to reduce the liabilities of Your Partnership, it is possible
that future economic, market, legal, tax or other considerations may cause the
general partner of Your Partnership to reduce the liabilities of Your
Partnership. If the liabilities of Your Partnership were to be reduced, and you
do not tender all of your Units pursuant to
    
 
                                      S-30
<PAGE>   35
 
   
     the Offer, you will be treated as receiving a hypothetical distribution of
cash resulting from a decrease in your share of the liabilities of Your
Partnership. Any such hypothetical distribution of cash would be treated as a
nontaxable return of capital to the extent of your adjusted tax basis in your
Units and thereafter as gain.
    
 
   
     RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD. Your Partnership
Agreement restricts you from making any transfer that would cause 50% or more of
the total interest in Your Partnership to be transferred within a 12-month
period. If we acquire a significant percentage of the interest in Your
Partnership, you may not be able to transfer your Units for the 12-month period
after the Offer.
    
 
   
                      BACKGROUND AND REASONS FOR THE OFFER
    
 
   
BACKGROUND OF THE OFFER
    
 
   
  General
    
 
   
     The Company is in the business of acquiring direct and indirect interests
in apartment properties such as the property owned by Your Partnership. The
Offer provides the Company with an opportunity to increase its ownership
interest in Your Partnership Property while providing you and other investors
with an opportunity to retain or liquidate your investment in Your Partnership
by tendering for OP Units or for cash.
    
 
   
     On June 3, 1997, the Company acquired NHP Partners, Inc., a Delaware
corporation ("NHP Partners"), and NHP Partners Two Limited Partnership, a
Delaware limited partnership ("Partners Two"), each formerly affiliated with NHP
Incorporated, a Delaware corporation ("NHP"). As a result of this acquisition,
the general partner of Your Partnership became a subsidiary of the Company and
an affiliate of the AIMCO Operating Partnership. Previously, on May 5, 1997, the
Company acquired 51.3% of the outstanding common stock of NHP, which manages the
property owned by Your Partnership. On December 8, 1997, the Company acquired
the remaining 48.7% of the outstanding common stock of NHP and thus owns 100% of
the outstanding common stock of NHP.
    
 
   
     We conducted two prior tender offers for Units of Your Partnership. In
August, 1997 we acquired a 0.7576% limited partnership interest in Your
Partnership through the first tender offer. In June 1998, we acquired an
additional 0.3788% limited partnership interest in Your Partnership through the
second tender offer. We currently own a 1.1364% limited partnership interest in
Your Partnership.
    
 
   
  Engagement of Fairness Opinion Provider
    
 
   
     The AIMCO Operating Partnership contacted Stanger in August 1998 to discuss
the possibility of Stanger providing a fairness opinion for the Offer. The AIMCO
Operating Partnership chose Stanger based on Stanger's expertise and strong
reputation in this area of work. The parties entered into a definitive agreement
dated August 28, 1998 for Stanger to provide such fairness opinion.
    
 
   
ALTERNATIVES CONSIDERED
    
 
   
     One of the reasons the Company acquired NHP Partners, Partners Two and NHP
was that the Company expected to make offers to acquire limited partnership
interests of some of the limited partnerships formerly controlled or managed by
NHP (the "NHP Partnerships"). Such offers would provide liquidity for the
limited partners of the NHP Partnerships. Such offers would also allow the AIMCO
Operating Partnership an opportunity to increase its ownership interest in
certain NHP Partnerships which would provide a larger asset and capital base and
increased diversification.
    
 
   
     The following is a brief discussion of the benefits and disadvantages of
alternatives to the Offer that could have been pursued by the general partner of
Your Partnership.
    
 
   
  Liquidation
    
 
   
     Benefits of Liquidation. An alternative to the Offer would be for Your
Partnership to sell its assets, distribute the net liquidation proceeds to the
partners in accordance with Your Partnership Agreement, and
    
 
                                      S-31
<PAGE>   36
 
   
     thereafter dissolve. Partners would be at liberty to use the net
liquidation proceeds after taxes for investment, business, personal or other
purposes, at their option. If Your Partnership were to sell its assets and
liquidate, the partners in Your Partnership would not need to rely upon
capitalization of income or other valuation methods to estimate the fair market
value of Your Partnership's assets. Instead, such assets would be valued through
negotiations between Your Partnership and the prospective purchasers (in many
cases unrelated third parties). Furthermore, Offerees are currently not
receiving any distribution on their Units.
    
 
   
     Disadvantages of Liquidation. A liquidating sale of part or all of the
Partnership Property would be a taxable event for partners of Your Partnership
and could result in significant amounts of taxable income to partners in Your
Partnership. In the opinion of the general partner of Your Partnership, the
present time may not be a desirable time to seek to sell the real estate assets
of Your Partnership in private transactions and any liquidation sale would be
uncertain. The general partner of Your Partnership believes it currently is in
the best interest of the partners of Your Partnership to continue holding Your
Partnership's real estate assets. Finally, under Your Partnership Agreement, a
sale of Your Partnership's assets and the subsequent liquidation of Your
Partnership could occur only with the consent of at least a majority of the
partners in Your Partnership. In the absence of such consent, a partner's only
option for liquidation would be to sell his Units in a private transaction. Any
such sale likely would be at a very substantial discount from the partner's pro
rata share of the fair market value of the Partnership Property and might
involve significant expense and delay.
    
 
   
  Continuation of the Property Partnerships Without the Option of the Offer
    
 
   
     Benefits of Continuation. A second alternative to the Offer would be for
Your Partnership to continue as a separate legal entity, with its own assets and
liabilities and continue to be governed by its existing partnership agreement
without the option of the Offer. A number of advantages would result from the
continued operation of Your Partnership. Given improving rental market
conditions, the level of distributions might increase over time. We believe it
is possible that the private resale market for apartment and retail properties
could improve over time, making a sale of the Partnership Property in a private
transaction at some point in the future a more attractive option than it is
currently.
    
 
   
     Disadvantages of Continuation. There are several risks and disadvantages
that result from continuing the operations of Your Partnership without the
option of the Offer. Your Partnership has required funding from its partners.
Continuation of Your Partnership's operations is dependent on additional funding
from partners or from other sources. Your Partnership faces maturity or balloon
payment dates on its mortgage loans and must either obtain refinancing or sell
its property. If Your Partnership were to continue operating as presently
structured, Your Partnership could be forced to borrow on terms that could
result in net losses from operations.
    
 
   
     In addition, continuation of Your Partnership as a separate entity without
the option of the Offer, would deny the partners the benefits that the general
partner of Your Partnership expects to result from the Offer. For example, a
partner of Your Partnership would have no opportunity for liquidity unless he
were to sell his Units in a private transaction. Any such sale would likely be
at a very substantial discount from the partner's pro rata share of the fair
market value of Your Partnership Property. Continuation without the option of
the Offer would deny Offerees the benefits of diversification into a company
which has a much larger and more diverse portfolio of apartment properties than
Your Partnership. Also, there are currently no distributions paid on Units while
there are distributions on OP Units.
    
 
   
EXPECTED BENEFITS OF THE OFFER
    
 
   
     We are in the business of acquiring direct and indirect interests in
apartment properties such as the property owned by Your Partnership. The Offer
provides us with an opportunity to increase our ownership interest in the
property of Your Partnership while providing you and other investors with an
opportunity to retain or liquidate your investment in Your Partnership or to
invest in the AIMCO Operating Partnership.

<PAGE>   37
 
   
     There are four principal advantages of tendering your Units for Preferred
OP Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Preferred OP Units. Upon redemption, we will give you, at our
       option, cash, shares of AIMCO's Class I Preferred Stock or shares of
       AIMCO's Class A Common Stock. AIMCO's Class A Common Stock and Class I
       Preferred Stock are listed and traded on the New York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you tender Units solely in exchange for Preferred OP Units.
    
 
   
     - Preferred Quarterly Distributions. We will pay fixed quarterly
       distributions of $       per unit on the Preferred OP Units before any
       distributions are paid to holders of Common OP Units. Your Partnership
       has not paid any distributions on your Units since the inception of Your
       Partnership.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
    
 
   
     There are five principal advantages of tendering your Units for Common OP
Units:
    
 
   
     - Enhanced Liquidity. After a one-year holding period, you may choose to
       redeem your Common OP Units. Upon redemption, we will give you, at our
       option, shares of AIMCO's Class A Common Stock (on a one-for-one basis,
       subject to adjustment in certain circumstances) or an equivalent amount
       of cash. AIMCO's Class A Common Stock is listed and traded on the New
       York Stock Exchange.
    
 
   
     - Tax Deferral. You will generally not recognize any immediate taxable gain
       if you tender Units solely in exchange for Common OP Units.
    
 
   
     - Quarterly Distributions. We pay quarterly distributions on the Common OP
       Units. For the quarter ended June 30, 1998, we paid distributions of
       $0.5625 on each of the Common OP Units (equivalent to $2.25 on an annual
       basis). Your Partnership has not paid any distributions on your Units
       since the inception of Your Partnership.
    
 
   
     - Growth Potential. Our organizational structure and access to capital
       enables us to pursue acquisition and development opportunities that are
       not available to Your Partnership. You would have the opportunity to
       participate in the growth of our enterprise and would benefit from any
       future increase in the AIMCO stock price and from any future increase in
       distributions on the Common OP Units.
    
 
   
     - Diversification. We have a substantially larger and more diverse
       portfolio of apartment properties than Your Partnership.
    
 
   
     The principal advantage if you tender your Units for cash is immediate
liquidity. However, tendering your Units for cash may cause you to recognize
taxable gain for federal income tax purposes.
    
 
   
     For a description of certain disadvantages of the Offer, see "Risk
Factors."

                                   THE OFFER
    
 
   
TERMS OF THE OFFER; EXPIRATION DATE
    
 
   
     We are offering to acquire up to      % of the outstanding Units of Your
Partnership for consideration per Unit of (i)        Preferred OP Units, (ii)
       Common OP Units, or (iii) $       in cash. If you tender Units pursuant
to the Offer, you may chose to receive any of such forms of consideration for
your Units or any combination of such forms of consideration.
    
 
   
     Upon the terms and subject to the conditions of the Offer set forth herein,
the AIMCO Operating Partnership will accept (and thereby purchase) Units that
are validly tendered on or prior to the Expiration Date set forth herein and not
withdrawn in accordance with the procedures set forth in "-- Withdrawal Rights."
For purposes of the Offer, the term "Expiration Date" shall mean 5:00 p.m.,
Denver, Colorado time, on                  , 1998, unless the AIMCO Operating
Partnership in its sole discretion shall have extended the period of time for
which the Offer is open, in which event the term "Expiration Date" with respect
to the Offer shall mean the latest time and date on which the Offer, as extended
by the AIMCO Operating Partnership, shall expire. See "-- Extension of Tender
Period; Termination; Amendment" for a description of the AIMCO Operating
Partnership's right to extend the period of time during which the Offer is open
and to amend or terminate the Offer.
    
 
   
     If, prior to the Expiration Date, the AIMCO Operating Partnership increases
the consideration offered to Offerees pursuant to the Offer, the increased
consideration will be paid for all Units the holders of which elected such form
of consideration accepted for payment pursuant to the Offer and the holders of
which have accepted such form of consideration, regardless of whether the Units
were tendered prior to or following the increase in consideration.
    
 
   
     The AIMCO Operating Partnership will, upon the terms and subject to the
conditions of the Offer, accept for payment and pay for all Units tendered
(subject to proration as described below), with appropriate adjustments to avoid
purchases that would violate the AIMCO Operating Partnership Agreement and any
relevant procedures or regulations promulgated by the AIMCO GP. The AIMCO
Operating Partnership will purchase all Units (subject to proration as described
below), which are validly tendered and not properly withdrawn on or prior to the
Expiration Date, upon the terms and subject to the conditions of the Offer.
    
 
   
     The Offer is conditioned on satisfaction of certain conditions. The Offer
is not conditioned upon any minimum amount of Units being tendered. See
"Conditions of the Offer," which sets forth in full the conditions of the Offer.
The AIMCO Operating Partnership reserves the right (but in no event shall be
obligated), in its sole discretion, to waive any or all of those conditions. If,
on or prior to the Expiration Date, any or all of the conditions have not been
satisfied or waived, the AIMCO Operating Partnership reserves the right to (i)
decline to purchase any of the Units tendered, terminate the Offer and return
all tendered Units to tendering Offerees, (ii) waive all the unsatisfied
conditions and purchase all Units validly tendered, (iii) extend the Offer and,
subject to the right of Offerees to withdraw Units until the Expiration Date,
retain the Units that have been tendered during the period or periods for which
the Offer is extended, and (iv) amend the Offer.
    
 
   
     For administrative purposes, the Offer will commence on                  ,
1998 and will be deemed to be made as of             , 1998. Any tender of Units
pursuant to the Offer and acceptance for payment will be effective as of
            , 1998 (subject to proration as described below). The effective date
will not affect the amount of distributions received by tendering Offerees.
    
 
   
ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS
    
 
   
     Upon the terms and subject to the conditions of the Offer, the AIMCO
Operating Partnership will purchase by accepting for payment and will pay for
all Units (subject to proration as described below), which are validly tendered
as promptly as practicable following the Expiration Date. The AIMCO Operating
Partnership reserves the right to accept for payment and pay for validly
tendered Units prior to the Expiration Date. A tendering beneficial owner of
Units whose Units are owned of record by an Individual Retirement
    
 
                                      S-34
<PAGE>   39
 
   
     Account or other qualified plan will not receive direct payment of the
Offer Price; rather, payment will be made to the custodian of such account or
plan. In all cases, payment for Units purchased pursuant to the Offer will be
made only after timely receipt by the Information Agent of a properly completed
and duly executed Letter of Transmittal and any other documents required by the
Letter of Transmittal. The Offer Price shall be reduced by any interim
distributions made by Your Partnership between                  and the
Expiration Date. See "Procedure for Tendering Units." UNDER NO CIRCUMSTANCES
WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN MAKING SUCH
PAYMENT.
    
 
   
     For purposes of the Offer, the AIMCO Operating Partnership will be deemed
to have accepted for payment pursuant to the Offer, and thereby purchased,
validly tendered Units, if, as and when the AIMCO Operating Partnership gives
verbal or written notice to the Information Agent of the AIMCO Operating
Partnership's acceptance of those Units for payment pursuant to the Offer.
Payment for Units accepted for payment pursuant to the Offer will be made
through the Information Agent, which will act as agent for tendering Offerees
for the purpose of receiving cash payments from the AIMCO Operating Partnership
and transmitting cash payments to tendering Offerees. OP Units will be issued
directly by the AIMCO Operating Partnership to those Offerees who elect to
receive OP Units in lieu of cash pursuant to the Offer.
    
 
   
     If any tendered Units are not accepted for payment for any reason, the
Letter of Transmittal with respect to such Units not purchased may be destroyed
by the AIMCO Operating Partnership or its agent. If for any reason, acceptance
for payment of, or payment for, any Units tendered pursuant to the Offer is
delayed or the AIMCO Operating Partnership is unable to accept for payment,
purchase or pay for Units tendered pursuant to the Offer, then, without
prejudice to the AIMCO Operating Partnership's rights under "-- Conditions of
the Offer," the Information Agent may, nevertheless, on behalf of the AIMCO
Operating Partnership retain tendered Units, and those Units may not be
withdrawn except to the extent that the tendering Offerees are entitled to
withdrawal rights as described in "-- Withdrawal Rights;" subject, however, to
the AIMCO Operating Partnership's obligation under Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), to pay
Offerees the Offer Price in respect of Units tendered or return those Units
promptly after termination or withdrawal of the Offer.
    
 
   
     The AIMCO Operating Partnership reserves the right to transfer or assign,
in whole or in part, to one or more of the AIMCO Operating Partnership's
affiliates, the right to purchase Units tendered pursuant to the Offer, but no
such transfer or assignment will relieve the AIMCO Operating Partnership of its
obligations under the Offer or prejudice the rights of tendering Offerees to
receive payment for Units validly tendered and accepted for payment pursuant to
the Offer.
    
 
   
PROCEDURE FOR TENDERING UNITS
    
 
   
  Valid Tender
    
 
   
     To validly tender Units pursuant to the Offer, a properly completed and
duly executed Letter of Transmittal and any other documents required by such
Letter of Transmittal must be received by the Information Agent, at its address
set forth on the back cover of the Prospectus or this Prospectus Supplement, on
or prior to the Expiration Date. An Offeree may tender all or any portion of the
Units owned by that Offeree. No alternative, conditional or contingent tenders
will be accepted.
    
 
   
  Signature Requirements
    
 
   
     IF THE LETTER OF TRANSMITTAL IS SIGNED BY THE REGISTERED HOLDER OF THE
UNITS AND PAYMENT IS TO BE MADE DIRECTLY TO THAT HOLDER, THEN NO SIGNATURE
GUARANTEE IS REQUIRED ON THE LETTER OF TRANSMITTAL. Similarly, if the Units are
tendered for the account of a member firm of a registered national securities
exchange, a member of the National Association of Securities Dealers, Inc. or a
commercial bank, savings bank, credit union, savings and loan association or
trust company having an office, branch or agency in the United States (each an
"Eligible Institution"), no signature guarantee is required on the Letter of
Transmittal. However, in all other cases, all signatures on the Letter of
Transmittal must be guaranteed by an Eligible Institution.

     In order for a tendering Offeree to participate in the Offer, its Units
must be validly tendered and not withdrawn on or prior to the Expiration Date.
    
 
   
     THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING HOLDER OF UNITS AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE INFORMATION
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY
DELIVERY.
    
 
   
  Appointment as Proxy
    
 
   
     By executing the Letter of Transmittal, a tendering Offeree irrevocably
appoints the AIMCO Operating Partnership and its designees as the Offeree's
proxies, in the manner set forth in the Letter of Transmittal, each with full
power of substitution, to the fullest extent of the Offeree's rights with
respect to the Units tendered by the Offeree and accepted for payment by the
AIMCO Operating Partnership. Each such proxy shall be considered coupled with an
interest in the tendered Units. Such appointment will be effective when, and
only to the extent that, the AIMCO Operating Partnership accepts the tendered
Units for payment. Upon such acceptance for payment, all prior proxies given by
the Offeree with respect to the Units will, without further action, be revoked,
and no subsequent proxies may be given (and if given will not be effective). The
AIMCO Operating Partnership and the designees of the AIMCO Operating Partnership
will, as to those Units, be empowered to exercise all voting and other rights of
the Offeree as they, in their sole discretion, may deem proper at any meeting of
Offerees, by written consent or otherwise. The AIMCO Operating Partnership
reserves the right to require that, in order for Units to be deemed validly
tendered, immediately upon the AIMCO Operating Partnership's acceptance for
payment for the Units, the AIMCO Operating Partnership must be able to exercise
full voting rights with respect to the Units, including voting at any meeting of
Offerees then scheduled or acting by written consent without a meeting. By
executing the Letter of Transmittal, a tendering Offeree agrees to execute all
such documents and take such other actions as shall be reasonably required to
enable the Units tendered to be voted in accordance with the directions of the
AIMCO Operating Partnership. The proxy and power of attorney granted by an
Offeree to the AIMCO Operating Partnership upon its execution of the Letter of
Transmittal shall remain effective and be irrevocable for a period of ten years
following the termination of the Offer.
    
 
   
  Assignment of Interest in Future Distributions and All Other Rights, Etc.
    
 
   
     Offerees who tender Units agree to irrevocably sell, assign, transfer,
convey and deliver to, or upon the order of, the AIMCO Operating Partnership,
all right, title and interest in and to such Units tendered that are accepted
for payment pursuant to the Offer, including, without limitation, (i) all of
such Offerees' interest in the capital of Your Partnership, and interest in all
profits, losses and distributions of any kind to which such Offerees shall at
any time be entitled in respect of the Units; (ii) all other payments, if any,
due or to become due to the Offeree in respect of the Units, under or arising
out of Your Partnership Agreement, whether as contractual obligations, damages,
insurance proceeds, condemnation awards or otherwise; (iii) all of such
Offerees' claims, rights, powers, privileges, authority, options, security
interests, liens and remedies, if any, under or arising out of Your Partnership
Agreement or such Offerees' ownership of the Units, including, without
limitation, all voting rights, rights of first offer, first refusal or similar
rights, and rights to be substituted as a limited partner of Your Partnership;
and (iv) all present and future claims, if any, of the Offeree against Your
Partnership or its partners under or arising out of Your Partnership Agreement
for monies loaned or advanced, for services rendered, for the management of Your
Partnership or otherwise.
    
 
   
  Election of Consideration
    
 
   
     Offerees may elect to receive Preferred OP Units, Common OP Units or cash
pursuant to the Offer, by so indicating in the appropriate space on the Letter
of Transmittal. In the event that an Offeree tenders Units but does not indicate
on the Letter of Transmittal which type of consideration the Offeree wants, the
AIMCO Operating Partnership will issue Preferred OP Units to such Offeree.

  Determination of Validity; Rejection of Units; Waiver of Defects; No
Obligation to Give Notice of Defects
    
 
   
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for payment of any tender of Units pursuant to the Offer
will be determined by the AIMCO Operating Partnership, in its sole discretion,
which determination shall be final and binding on all parties. The AIMCO
Operating Partnership reserves the absolute right to reject any or all tenders
of any particular Unit determined by it not to be in proper form or if the
acceptance of or payment for that Unit may, in the opinion of the AIMCO
Operating Partnership's counsel, be unlawful. The AIMCO Operating Partnership
also reserves the absolute right to waive or amend any of the conditions of the
Offer that it is legally permitted to waive as to the tender of any particular
Unit and to waive any defect or irregularity in any tender with respect to any
particular Unit of any particular Offeree. The AIMCO Operating Partnership's
interpretation of the terms and conditions of the Offer (including the Letters
of Transmittal) will be final and binding on all parties. No tender of Units
will be deemed to have been validly made unless and until all defects and
irregularities have been cured or waived. Neither the AIMCO Operating
Partnership, the Information Agent nor any other person will be under any duty
to give notification of any defects or irregularities in the tender of any Units
or will incur any liability for failure to give any such notification.
    
 
   
  Backup Federal Income Tax Withholding
    
 
   
     To prevent the possible application of back-up federal income tax
withholding of 31% with respect to payment of the Offer Price, a tendering
Offeree must provide the AIMCO Operating Partnership with the Offeree's correct
taxpayer identification number. See the Instructions to the Letter of
Transmittal and "Certain Federal Income Tax Matters."
    
 
   
  FIRPTA Withholding
    
 
   
     To prevent the withholding of federal income tax in an amount equal to 10%
of the amount realized pursuant to the Offer, each tendering Offeree must
certify under penalty of perjury that the Offeree is not a foreign person. See
the Instructions to the Letter of Transmittal and "Certain Federal Income Tax
Matters."
    
 
   
  Binding Agreement
    
 
   
     A tender of Units pursuant to any of the procedures described above and the
acceptance for payment of such Units will constitute a binding agreement between
the tendering Offeree and the AIMCO Operating Partnership on the terms set forth
in this Prospectus Supplement.
    
 
   
WITHDRAWAL RIGHTS
    
 
   
     Tenders of Units pursuant to the Offer may be withdrawn at any time prior
to acceptance for payment as provided in this Prospectus Supplement.
    
 
   
     For withdrawal to be effective, a written notice of withdrawal must be
timely received by the Information Agent at its address set forth on the back
cover of this Prospectus Supplement. Any such notice of withdrawal must specify
the name of the person who tendered, the number of Units to be withdrawn and the
name of the registered holder of such Units, if different from the person who
tendered. In addition, the notice of withdrawal must be signed by the person(s)
who signed the Letter of Transmittal in the same manner as the Letter of
Transmittal was signed.
    
 
   
     If purchase of, or payment for, Units is delayed for any reason or if the
AIMCO Operating Partnership is unable to purchase or pay for Units for any
reason, then, without prejudice to the AIMCO Operating Partnership's rights
under the Offer, tendered Units may be retained by the Information Agent and may
not be withdrawn, except to the extent that tendering Offerees are entitled to
withdrawal rights as set forth herein; subject, however, to the AIMCO Operating
Partnership's obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to
pay Offerees the Offer Price in respect of Units tendered or return those Units
promptly after termination or withdrawal of the Offer.
    
 
                                      S-37
<PAGE>   42
 
   
     Any Units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of the Offer.
    
 
   
     All questions as to the validity and form (including time of receipt) of
notices of withdrawal will be determined by the AIMCO Operating Partnership, in
its sole discretion, which determination shall be final and binding on all
parties. Neither the AIMCO Operating Partnership, the Information Agent nor any
other person will be under any duty to give notification of any defects or
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
    
 
   
EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT
    
 
   
     The AIMCO Operating Partnership expressly reserves the right, in its sole
discretion, at any time and from time to time, (i) to extend the period of time
during which the Offer is open and thereby delay acceptance for payment of, and
for, any Units, (ii) to terminate any of the Offer and not accept for payment
any Units not theretofore accepted for payment or paid for, (iii) upon the
occurrence of any of the conditions specified in "-- Conditions of the Offer,"
to delay the acceptance for payment of, or for, any Units not already accepted
for payment or paid for and (iv) to amend any of the Offer in any respect
(including, without limitation, by increasing the consideration offered,
increasing or decreasing the Units being sought, or both). Notice of any such
extension, termination or amendment will promptly be disseminated to Offerees in
a manner reasonably designed to inform Offerees of such change. In the case of
an extension of the Offer, the extension will be followed by a press release or
public announcement which will be issued no later than 9:00 a.m., Denver,
Colorado time, on the next business day after the scheduled Expiration Date of
the Offer, in accordance with Rule 14e-1(d) under the Exchange Act.
    
 
   
     If the AIMCO Operating Partnership extends the Offer, or if the AIMCO
Operating Partnership (whether before or after its acceptance for payment of
Units) is delayed in its payment for Units or is unable to pay for Units
pursuant to the Offer for any reason, then, without prejudice to the AIMCO
Operating Partnership's rights under the Offer, the Information Agent may retain
tendered Units and those Units may not be withdrawn except to the extent
tendering Offerees are entitled to withdrawal rights as described in
"-- Withdrawal Rights;" subject, however, to the AIMCO Operating Partnership's
obligation, pursuant to Rule 14e-l(c), under the Exchange Act, to pay Offerees
the Offer Price in respect of Units tendered or return those Units promptly
after termination or withdrawal of the Offer.
    
 
   
     If the AIMCO Operating Partnership makes a material change in the terms of
the Offer, or if it waives a material condition to the Offer, the AIMCO
Operating Partnership will extend the Offer and disseminate additional tender
offer materials to the extent required by Rule 14e-1 under the Exchange Act. The
minimum period during which the Offer must remain open following any material
change in the terms of the Offer, other than a change in price or a change in
percentage of securities sought or a change in any dealer's soliciting fee, will
depend upon the facts and circumstances, including the materiality of the
change. With respect to a change in price or, subject to certain limitations, a
change in the percentage of securities sought or a change in any dealer's
soliciting fee, a minimum of ten business days from the date of such change is
generally required to allow for adequate dissemination to Offerees. Accordingly,
if prior to the Expiration Date, the AIMCO Operating Partnership increases
(other than increases of not more than two percent of the outstanding Units) or
decreases the number of Units being sought, or increases or decreases the
consideration offered pursuant to the Offer, and if the Offer is scheduled to
expire at any time earlier than the tenth business day from the date that notice
of such increase or decrease is first published, sent or given to Offerees, the
Offer will be extended at least until the expiration of such ten business days.
As used herein, "business day" means any day other than a Saturday, Sunday or a
federal holiday, and consists of the time period from 12:01 a.m. through 12:00
midnight, New York City time.
    
 
   
PRORATION
    
 
   
     If the number of Units properly tendered and not withdrawn prior to the
Expiration Date does not exceed   % of the outstanding Units, the AIMCO
Operating Partnership, upon the terms and subject to the conditions of the Offer
will purchase all such Units so tendered and not withdrawn.
    
 
                                      S-38
<PAGE>   43
 
   
     If the number of Units properly tendered and not withdrawn prior to the
Expiration Date exceeds   % of the outstanding Units, the AIMCO Operating
Partnership, upon the terms and subject to the conditions of the Offer, will
accept for purchase Units in the following order of priority:
    
 
   
        (1) All Units properly tendered and not withdrawn prior to the
     Expiration Date by any Offeree holding one or fewer Units who tenders all
     Units held by such Offeree; and
    
 
   
        (2) After purchase of the foregoing Units, all other Units properly
     tendered and not withdrawn prior to the Expiration Date on a pro rata
     basis, with adjustments to avoid resulting ownership of less than one Units
     by a tendering Offeree.
    
 
   
     Following the Expiration Date, the AIMCO Operating Partnership may renew
the Offer one or more times on the same terms as described in this Prospectus
Supplement. If the number of Units properly tendered and not withdrawn prior to
the expiration of any such renewal (together with Units previously purchased in
the Offer) is                or less, the AIMCO Operating Partnership will
purchase such Units so tendered and not withdrawn. If the number of Units in
Your Partnership properly tendered and not withdrawn prior to the expiration of
any such renewal (together with any Units previously purchased in this Exchange
Offer) is greater than                , the AIMCO Operating Partnership will
purchase Units in the order of priority described in the preceding paragraph.
    
 
   
     In the event that OP Units of tendered Units is required, the AIMCO
Operating Partnership will determine the final OP Units factor as promptly as
practicable after the Expiration Date or any renewal of the Offer.
    
 
   
FRACTIONAL OP UNITS
    
 
   
     We will issue fractional Common OP Units and Preferred OP Units.
    
 
   
FUTURE PLANS OF THE AIMCO OPERATING PARTNERSHIP
    
 
   
     As described above under "Background and Reasons for the Offer," the AIMCO
Operating Partnership owns the general partner of Your Partnership and thereby
controls the management of Your Partnership. In addition, the Company indirectly
owns a 95% non-voting interest in the company that manages Your Partnership
Property. The AIMCO Operating Partnership currently intends that, upon
consummation of the Offer, Your Partnership will continue its business and
operations substantially as they are currently being conducted. The Offer is not
expected to have any effect on Your Partnership's financial condition or results
of operations.
    
 
   
     After the completion or termination of the Offer, the AIMCO Operating
Partnership and its affiliates may acquire additional Units or sell Units. Any
acquisition may be made through private purchases, market purchases or
transactions effected on a so-called partnership trading board, through one or
more future tender or exchange offers, by merger, consolidation or by any other
means deemed advisable. Any acquisition may be at a price higher or lower than
the price to be paid for the Units purchased pursuant to the Offer, and may be
for cash, limited partnership interests in the AIMCO Operating Partnership or
other consideration. The AIMCO Operating Partnership also may consider selling
some or all of the Units it acquires pursuant to the Offer to persons not yet
determined, which may include affiliates of the AIMCO Operating Partnership. The
AIMCO Operating Partnership may also buy Your Partnership Property, although it
has no present intention to do so. There can be no assurance, however, that the
AIMCO Operating Partnership will initiate or complete, or will cause Your
Partnership to initiate or complete, any subsequent transaction during any
specific time period following the Expiration Date or at all.
    
 
   
     We currently intend that, upon consummation of the Offer, Your Partnership
will continue its business and operations substantially as they are currently
being conducted. We do not have any present plans or proposals which relate to
or would result in any material changes in Your Partnership's structure or
business. We have no present intention to cause Your Partnership to sell its
property or to prepay the current mortgage within any specified time period.

VOTING BY THE AIMCO OPERATING PARTNERSHIP
    
 
   
     If the AIMCO Operating Partnership acquires a substantial amount of Units
pursuant to the Offer, the AIMCO Operating Partnership may be in a position to
influence voting decisions with respect to Your Partnership. Under Your
Partnership Agreement, holders of outstanding Units are entitled to take action
with respect to a variety of matters, including dissolution and most types of
amendments to Your Partnership Agreement. See "Comparison of Your Units and
AIMCO OP Units -- Voting Rights."
    
 
   
DISSENTERS' RIGHTS
    
 
   
     Neither Your Partnership Agreement nor applicable law provides any right
for Offerees to have their respective Units appraised or redeemed in connection
with or as a result of the Offer. Each Offeree has the opportunity to make an
individual decision on whether to tender Units in the Offer.
    
 
   
CONDITIONS OF THE OFFER
    
 
   
     Notwithstanding any other provisions of the Offer, the AIMCO Operating
Partnership shall not be required to accept for payment and pay for any Units

          , 1998 and at or before the time of acceptance for payment of any such

     Partnership owns or operates the Partnership Property, which change, in the
     sole judgment of the AIMCO Operating Partnership, is or may be materially
     adverse to Your Partnership or the value of the Units to the AIMCO
     Operating Partnership, or the AIMCO Operating Partnership shall have become
     aware of any facts relating to Your Partnership, its indebtedness or its
     operations which, in the sole judgment of the AIMCO Operating Partnership,

     Partnership or the value of the Units to the AIMCO Operating Partnership;
     or

     case of any of the foregoing existing at the time of the commencement of
     the Offer, in the sole judgment of the AIMCO Operating Partnership, a
     material acceleration or worsening thereof; or
    
 
   
          (c) there shall have been threatened, instituted, or pending any
     action, proceeding, application or counterclaim by any federal, state,
     local or foreign government, governmental authority or governmental agency,
     or by any other person, before any governmental authority, court or
     regulatory or administrative agency, authority or tribunal, which (i)
     challenges or seeks to challenge the acquisition by the AIMCO Operating
     Partnership of the Units, restrains, or prohibits or delays the making or
     consummation of the Offer, prohibits the performance of any of the
     contracts or other arrangements entered into by the AIMCO Operating
     Partnership (or any affiliates of the AIMCO Operating Partnership) in
     connection with the acquisition of the Units, or (if there is a substantial
     likelihood of success on the merits) seeks to

     the Units including, but not limited to, the right to vote the Units
     purchased by it on all matters properly presented to the Offerees or (v)
     might result, in the sole judgment of the AIMCO Operating Partnership, in a
     diminution in the value of Your Partnership or a limitation of the benefits
     expected to be derived by the AIMCO Operating Partnership as a result of
     the transactions contemplated by the Offer or the value of the Units to the
     AIMCO Operating Partnership; or

     its or their assets is in default or has been accelerated; or
    
 
   
          (f) a tender or exchange offer for any Units shall have been commenced
     or publicly proposed to be made by another person or "group" (as defined in
     Section 13(d)(3) of the Exchange Act), or it shall have been publicly
     disclosed or the AIMCO Operating Partnership shall have otherwise learned
     that (i) any person or group shall have acquired or proposed or be
     attempting to acquire beneficial ownership of more than four percent of the
     Units, or shall have been granted any option, warrant or right, conditional
     or otherwise, to acquire beneficial ownership of more than four percent of
     the Units, or (ii) any person or group shall have entered into a definitive
     agreement or an agreement in principle or
    
 
                                      S-41
<PAGE>   46
 
   
     made a proposal with respect to a merger, consolidation, purchase or lease
     of assets, debt refinancing or other business combination with or involving
     Your Partnership.
    
 
   
     The foregoing conditions are for the sole benefit of the AIMCO Operating
Partnership and may be asserted by the AIMCO Operating Partnership regardless of
the circumstances giving rise to such conditions or may be waived by the AIMCO
Operating Partnership in whole or in part at any time and from time to time in
its sole discretion. The failure by the AIMCO Operating Partnership at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right, the waiver of any such right with respect to any particular facts or
circumstances shall not be deemed a waiver with respect to any other facts or
circumstances and each right shall be deemed a continuing right which may be
asserted at any time and from time to time.
    
 
   
EFFECTS OF THE OFFER
    
 
   
  Future Control by the Company
    
 
   
     Because the general partner of Your Partnership is a subsidiary of the
Company, the Company has control over the management of Your Partnership. In
addition, if the AIMCO Operating Partnership acquires Units in the Offer, the
Company will increase its ability to influence voting decisions with respect to
Your Partnership. Furthermore, in the event that the AIMCO Operating Partnership
acquires a substantial number of Units pursuant to the Offer, removal of the
general partner of Your Partnership (which general partner is controlled by the
Company) by the limited partners (other than those controlled by the Company)
may become more difficult or impossible. The Company also indirectly owns 95%
non-voting interest in the company which manages Your Partnership Property. In
the event that the AIMCO Operating Partnership acquires a substantial number of
Units pursuant to the Offer, removal by the limited partners (other than those
controlled by the Company) of the manager of Your Partnership Property may
become more difficult or impossible.
    
 
   
  Distributions to the AIMCO Operating Partnership
    
 
   
     As a result of the Offer, the AIMCO Operating Partnership, in its capacity
as a limited partner of Your Partnership, will participate in any subsequent
distributions to limited partners to the extent of its interest in Your
Partnership, including the Units purchased pursuant to the Offer.
    
 
   
  Partnership Business
    
 
   
     The Offer will not materially affect the operation of Your Partnership
Property owned by Your Partnership, because the AIMCO Operating Partnership will
continue to control the general partner of Your Partnership and the management
of Your Partnership, and the Property Manager will continue to manage Your
Partnership Property.
    
 
   
CERTAIN LEGAL MATTERS
    
 
   
     General. Except as set forth in this section, the AIMCO Operating
Partnership is not, based on information provided by the general partner of Your
Partnership, aware of any licenses or regulatory permits that would be material
to the business of Your Partnership, taken as a whole, and that might be
adversely affected by the AIMCO Operating Partnership's acquisition of Units as
contemplated herein, or any filings, approvals or other actions by or with any
domestic or foreign governmental authority or administrative or regulatory
agency that would be required prior to the acquisition of Units by the AIMCO
Operating Partnership pursuant to the Offer as contemplated herein. While there
is no present intent to delay the purchase of Units tendered pursuant to the
Offer pending receipt of any such additional approval or the taking of any such
action, there can be no assurance that any such additional approval or action,
if needed, would be obtained without substantial conditions or that adverse
consequences might not result to Your Partnership's business, or that certain
parts of Your Partnership's business might not have to be disposed of or other
substantial conditions complied with in order to obtain such approval or action,
any of which could cause the
    
 
                                      S-42
<PAGE>   47
 
   
     AIMCO Operating Partnership to elect to terminate the Offer without
purchasing Units thereunder. The AIMCO Operating Partnership's obligation to
purchase and pay for Units is subject to certain conditions, including
conditions related to the legal matters discussed in this section.
    
 
   
     Antitrust. The AIMCO Operating Partnership does not believe that the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable
to the acquisition of Units contemplated by the Offer.
    
 
   
     Margin Requirements. The Units are not "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System and,
accordingly, those regulations generally are not applicable to the Offer.
    
 
   
     State Laws. The AIMCO Operating Partnership is not aware of any
jurisdiction in which the making of the Offer is not in compliance with
applicable law. If the AIMCO Operating Partnership becomes aware of any
jurisdiction in which the making of the Offer would not be in compliance with
applicable law, the AIMCO Operating Partnership will make a good faith effort to
comply with any such law. If, after such good faith effort, the AIMCO Operating
Partnership cannot comply with any such law, the Offer will not be made to (nor
will tenders be accepted from or on behalf of) limited partners residing in such
jurisdiction. In those jurisdictions whose securities or blue sky laws require
the Offer to be made by a licensed broker or dealer, the Offer shall be made on
behalf of the AIMCO Operating Partnership, if at all, only by one or more
registered brokers or dealers licensed under the laws of that jurisdiction.
    
 
   
FEES AND EXPENSES
    
 
   
     Except as set forth in this section, the AIMCO Operating Partnership will
not pay any fees or commissions to any broker, dealer or other person for
soliciting tenders of Units pursuant to the Offer. The AIMCO Operating
Partnership has retained               to act as Information Agent in connection
with the Offer. The Information Agent may contact holders of Units by mail,
telephone, telex, telegraph and personal interview and may request brokers,
dealers and other nominee Offerees to forward materials relating to the Offer to
beneficial owners of the Units. The AIMCO Operating Partnership will pay the
Information Agent reasonable and customary compensation for its services in
connection with the Offer, plus reimbursement for out-of-pocket expenses, and
will indemnify the Information Agent against certain liabilities and expenses in
connection therewith, including liabilities under the federal securities laws.
The AIMCO Operating Partnership will also pay all costs and expenses of printing
and mailing the Offer and its legal fees and expenses. The AIMCO Operating
Partnership will also pay the fees of Stanger for providing the fairness
opinions for the Offer. The AIMCO Operating Partnership estimates that its total
costs and expenses in making the Offer (excluding the purchase price of the
Units payable to the Offerees) will be approximately $              .
    
 
   
ACCOUNTING TREATMENT
    
 
   
     Upon consummation of the Offer, the AIMCO Operating Partnership will
account for the investment in the Units acquired in the Offer under the purchase
method of accounting. There will be no effect on the accounting treatment of
Your Partnership as a result of the Offer.
    
 
   
                       DESCRIPTION OF PREFERRED OP UNITS
    
 
   
GENERAL
    
 
   
     The Preferred OP Units are a class of Partnership Preferred Units of the
AIMCO Operating Partnership.
    
 
   
RANKING
    
 
   
     The Preferred OP Units will, with respect to distribution rights and rights
upon liquidation, dissolution or winding up of the AIMCO Operating Partnership,
effectively rank:(i) prior or senior to the Common OP Units and any other
interest in the AIMCO Operating Partnership if the holders of Preferred OP Units
shall be entitled to the receipt of distributions and amounts distributable upon
liquidation, dissolution or winding
    
 
                                      S-43
<PAGE>   48
 
   
     up in preference or priority to the holders of such interest (the Common OP
Units and such other interests are collectively referred to herein as "Junior
Units"); (ii) on a parity with the Class B Partnership Preferred Units, the
Class C Partnership Preferred Units, the Class D Partnership Preferred Units,
the Class G Partnership Preferred Units, the Class H Partnership Preferred
Units, and with any other interest in the AIMCO Operating Partnership if the
holders of such interest and the Preferred OP Units shall be entitled to the
receipt of distributions and amounts distributable upon liquidation, dissolution
or winding up in proportion to their respective amounts of accumulated, accrued
and unpaid distributions or stated preferences, without preference or priority
of one over the other ("Parity Units"); and (iii) junior to any interest in the
AIMCO Operating Partnership if the holders of such interest shall be entitled to
the receipt of distributions or amounts distributable upon liquidation,
dissolution or winding up in preference or priority to the holders of the
Preferred OP Units ("Senior Units"). Junior Units, Parity Units and Senior Units
may be issued from time to time by the AIMCO Operating Partnership without any
approval or consent by holders of the Preferred OP Units.
    
 
   
     Although proceeds upon liquidation, dissolution or winding up of the AIMCO
Operating Partnership will be made in accordance with the positive balance of
all partners capital accounts, the AIMCO Operating Partnership creates, to the
extent possible, the preference upon such events by specially allocating income,
if necessary, to the Preferred OP Units in an amount equal to their liquidation
preference.
    
 
   
DISTRIBUTIONS
    
 
   
     Holders of Preferred OP Units are entitled to receive, when and as declared
by the Board of Directors of the general partner of the AIMCO Operating
Partnership, quarterly cash distributions at the rate of $       per Preferred
OP Units (equivalent to      % per annum of the $100 stated liquidation
preference); provided, however, that at any time and from time to time on or
after the fifth anniversary of the issue date of the Preferred OP Units, the
AIMCO Operating Partnership may adjust the annual distribution rate on the
Preferred OP Units to the lower of (i)        % 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 most recently issued AIMCO non-convertible
preferred stock which ranks on a parity with its Class H Cumulative Preferred
Stock. Such adjustment shall become effective upon the date the AIMCO Operating
Partnership issues a notice to such effect to the holders of the Preferred OP
Units. Such distributions are 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 OP Units are
issued on any day other than a Distribution Payment Date, the first distribution
payable on such Preferred OP Units are prorated for the portion of the quarterly
period that such Preferred OP Units are outstanding on the basis of twelve
30-day months and a 360-day year. Distributions are payable in arrears to
holders of record as they appear on the records of the AIMCO Operating
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 OP Units will not be entitled to receive any
distributions in excess of cumulative distributions on the Preferred OP 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 OP Units that may be in
arrears. Holders of any Preferred OP Units that are issued after the date of
original issuance are entitled to receive the same distributions as holders of
any Preferred OP Units issued on the date of original issuance.
    
 
   
     When distributions are not paid in full upon the Preferred OP Units or any
Parity Units, or a sum sufficient for such payment is not set apart, all
distributions declared upon the Preferred OP Units and any Parity Units shall be
declared ratably in proportion to the respective amounts of distributions
accumulated, accrued and unpaid on the Preferred OP Units and accumulated,
accrued and unpaid on such Parity Units. Except as set forth in the preceding
sentence, unless distributions on the Preferred OP Units equal to the full
amount of accumulated, accrued 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
    
 
                                      S-44
<PAGE>   49
 
   
     payment by the AIMCO Operating Partnership with respect to any Parity
Units. Unless full cumulative distributions (including all accumulated, accrued
and unpaid distributions) on the Preferred OP Units have been declared and paid,
or declared and set apart for payment, for all past distribution periods, no
distributions (other than distributions or distributions paid in Junior Units or
options, warrants or rights to subscribe for or purchase Junior Units) may be
declared or paid or set apart for payment by the AIMCO Operating Partnership and
no other distribution of cash or other property may be declared or made,
directly or indirectly, by the AIMCO Operating Partnership with respect to any
Junior Units, nor shall any Junior Units be redeemed, purchased or otherwise
acquired (except for a redemption, purchase or other acquisition of Common OP
Units made for purposes of an employee incentive or benefit plan of AIMCO, the
AIMCO Operating Partnership or any subsidiary) for any consideration (or any
monies be paid to or made available for a sinking fund for the redemption of any
such Junior Units), directly or indirectly, by the AIMCO Operating Partnership
(except by conversion into or exchange for Junior Units, or options, warrants or
rights to subscribe for or purchase Junior Units), nor shall any other cash or
other property be paid or distributed to or for the benefit of holders of Junior
Units. Notwithstanding the foregoing provisions of this paragraph, the AIMCO
Operating Partnership shall not be prohibited from (i) declaring or paying or
setting apart for payment any distribution on any Parity Units or (ii)
redeeming, purchasing or otherwise acquiring any Parity Units, in each case, if
such declaration, payment, redemption, purchase or other acquisition is
necessary to maintain AIMCO's qualification as a REIT.
    
 
   
ALLOCATION
    
 
   
     The Preferred OP Units shall be allocated net income of the AIMCO Operating
Partnership in an amount equal to the distribution made on such Preferred OP
Unit during the taxable year. The Preferred OP Units also will generally be
allocated any net loss of the AIMCO Operating Partnership that is not allocated
to Common OP Units or other interests of the AIMCO Operating Partnership.
    
 
   
LIQUIDATION PREFERENCE
    
 
   
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the AIMCO Operating Partnership, before any allocation of income or gain by the
AIMCO Operating Partnership shall be made to or set apart for the holders of any
Junior Units, to the extent possible, the holders of Preferred OP Units shall be
entitled to be allocated income and gain to effectively enable them to receive a
liquidation preference (the "Liquidation Preference") of $100 per Preferred OP
Units (the "Stated Preference"), plus 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. Until the holders of the Preferred OP Units have been paid the
Liquidation Preference in full, no allocation of income gain is made to any
holder of Junior Units upon the liquidation, dissolution or winding up of the
AIMCO Operating Partnership. If, upon any liquidation, dissolution or winding up
of the AIMCO Operating Partnership, the assets of the AIMCO Operating
Partnership, or proceeds thereof, distributable among the holders of Preferred
OP Units shall be insufficient to pay in full the above described preferential
amount and liquidating payments on any Parity Units, then following certain
allocations made by the AIMCO Operating Partnership, such assets, or the
proceeds thereof, shall be distributed among the holders of Preferred OP Units
and any such Parity Units ratably in the same proportion as the respective
amounts that would be payable on such Preferred OP Units and any such Parity
Units if all amounts payable thereon were paid in full. A voluntary or
involuntary liquidation, dissolution or winding up of the AIMCO Operating
Partnership will not include a consolidation or merger of the AIMCO Operating
Partnership with one or more partnerships, corporations or other entities, or a
sale or transfer of all or substantially all of the AIMCO Operating
Partnership's assets. Upon any liquidation, dissolution or winding up of the
AIMCO Operating Partnership, after all allocations shall have been made in full
to the holders of Preferred OP Units and any Parity Units to enable them to
receive their Liquidation Preference, any Junior Units shall be entitled to
receive any and all assets remaining to be paid or distributed, and the holders
of the Preferred OP Units and any Parity Units shall not be entitled to share
therein.

REDEMPTION
    
 
   
     The Preferred OP Units may not be redeemed at the option of the AIMCO
Operating Partnership, and will not be required to be redeemed or repurchased by
the AIMCO Operating Partnership or AIMCO except if a holder of a Preferred OP
Unit effects a redemption, as described below. The AIMCO Operating Partnership
or AIMCO may purchase Preferred OP Units from time to time in the open market,
by tender or exchange offer, in privately negotiated purchases or otherwise.
After a one-year holding period, a holder may redeem Preferred OP Units and
receive in exchange therefor, at the AIMCO Operating Partnership's option, (i)
subject to the terms of any Senior Units, cash in an amount equal to the
Liquidation Preference of the Preferred OP Units tendered for redemption, (ii) a
number of shares of Class I Preferred Stock of AIMCO that pay an aggregate
amount of dividends equivalent to the distributions on the Preferred OP Units
tendered for redemption; provided that such shares are part of a class or series
of preferred stock that is then listed on the New York Stock Exchange or another
national securities exchange, or (iii) a number of shares of Class A Common
Stock of AIMCO that is equal in Value to the Liquidation Preference of the
Preferred OP Units tendered for redemption. The "Value" of shares of Class A
Common Stock will be determined based on a 10-day average trading price of the
shares, as set forth in the AIMCO Operating Partnership Agreement. If shares of
Class I Preferred Stock or Class A Common Stock of AIMCO are issued in exchange
for any Preferred OP Units tendered for redemption, the Preferred OP Units that
are acquired by AIMCO will be converted to a class of AIMCO Operating
Partnership units that corresponds to the class of stock so issued.
    
 
   
VOTING RIGHTS
    
 
   
     Except as otherwise required by applicable law or in the AIMCO Operating
Partnership Agreement, the holders of the Preferred OP Units will have the same
voting rights as holders of the Common OP Units. See "Description of OP Units"
in the accompanying Prospectus. So long as any Preferred OP Units are
outstanding, in addition to any other vote or consent of partners required by
law or by the AIMCO Operating Partnership Agreement, the affirmative vote or
consent of holders of at least 50% of the outstanding Preferred OP Units will be
necessary for effecting any amendment of any of the provisions of the
Partnership Unit Designation of the Preferred OP Units that materially and
adversely affects the rights or preferences of the holders of the Preferred OP
Units. The creation or issuance of any class or series of AIMCO Operating
Partnership units, including, without limitation, any AIMCO Operating
Partnership units that may have rights senior or superior to the Preferred OP
Units, shall not be deemed to materially adversely affect the rights or
preferences of the holders of Preferred OP Units. With respect to the exercise
of the above described voting rights, each Preferred OP Units shall have one (1)
vote per Preferred OP Unit.
    
 
   
RESTRICTIONS ON TRANSFER
    
 
   
     Preferred OP Units will be subject to the same restrictions on transfer
applicable to Common OP Units, as set forth in the AIMCO Operating Partnership
Agreement.

                     DESCRIPTION OF CLASS I PREFERRED STOCK
    
 
   
     The Class I Preferred Stock (a) ranks prior to the Common Stock and will
rank prior to the Class E Preferred Stock to be issued in the Insignia Merger,
and any other class or series of capital Stock of AIMCO if the holders of the
Class I Preferred Stock are to be entitled to the receipt of dividends or of
amounts distributable upon liquidation, dissolution, and winding-up in
preference or priority to the holders of shares of such class or series ("Class
I Junior Stock"), (b) ranks on parity with the Class B Preferred Stock, the
Class C Preferred Stock, the Class D Preferred Stock, the Class G Preferred
Stock, the Class H Preferred Stock and with any other class or series of capital
stock of AIMCO, if the holders of such class of stock or series and the Class I
Preferred Stock shall be entitled to the receipt of dividends and of amounts
distributable upon liquidation, dissolution or winding-up in proportion to their
respective amounts of accrued and unpaid dividends per share or liquidation
preferences, without preference or priority one over the other ("Class I Parity
Stock") and (c) ranks junior to any class or series of capital stock of AIMCO if
the holders of such class or series shall be entitled to the receipt of
dividends or amounts distributable upon liquidation, dissolution or winding-up
in preference or priority to the holders of the Class I Preferred Stock ("Class
I Senior Stock").
    
 
   
     Holders of Class I Preferred Stock are entitled to receive cash dividends
at the rate of      % per annum of the $25 liquidation preference (equivalent to
$     per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing January 15, 1999. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class I
Junior Stock, the holders of Class I Preferred Stock shall be entitled to
receive a liquidation preference of $25 per share (the "Class I Liquidation
Preference"), plus an amount equal to all accumulated, accrued and unpaid
dividends to the date of final distribution to such holders; but such holders
shall not be entitled to any further payment. If proceeds available for
distribution shall be insufficient to pay the preference described above and any
liquidating payments on any other shares of any class or series of Class I
Parity Stock, then such proceeds shall be distributed among the holders of Class
I Preferred Stock and any such other Class I Parity Stock ratably in the same
proportion as the respective amount that would be payable on such Class I
Preferred Stock and any such other Class I Parity Stock if all amounts payable
thereon were paid in full.
    
 
   
     On and after                     ,           , AIMCO may redeem shares of
Class I Preferred Stock, in whole or in part, at a cash redemption price equal
to 100% of the Class I Liquidation Preference plus all accrued and unpaid
dividends to the date fixed for redemption. The Class I Preferred Stock has no
stated maturity and will not be subject to any sinking fund or mandatory
redemption provisions.
    
 
   
     Holders of shares of Class I Preferred Stock have no voting rights, except
that if distributions on Class I Preferred Stock or any series or class of Class
I Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class I Preferred Stock (voting together as a single class with all
other shares of Class I Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class I Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
I Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class I Preferred Stock, and to
approve the issuance of any capital stock that ranks senior to the Class I
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
    
 
   
     Ownership of shares of Class I Preferred Stock by any person will be
limited such that the sum of the aggregate value of all capital stock of AIMCO
(including all shares of Class I Preferred Stock) owned directly or
constructively by such person may not exceed 8.7% (or 15% in the case of certain
pension trusts, registered investment companies and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO (the "Class I Preferred Ownership
Limit"). The AIMCO Board may waive such ownership limit if evidence satisfactory
to the
    
 
                                      S-47
<PAGE>   52
 
   
     AIMCO Board and AIMCO's tax counsel is presented that such ownership will
not then or in the future jeopardize AIMCO's status as a REIT. As a condition of
such waiver, the AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class I Preferred Stock in excess of the Class I
Preferred Ownership Limit, or shares of Class I Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee would acquire
no rights to the Class I Preferred Stock. Shares of Class I Preferred Stock
transferred in excess of the Class I Preferred Ownership Limit or other
applicable limitations will automatically be transferred to a trust for the
exclusive benefit of one or more qualifying charitable organizations to be
designated by AIMCO. Shares transferred to such trust will remain outstanding,
and the trustee of the trust will have all voting and dividend rights pertaining
to such shares. The trustee of such trust may transfer such shares to a person
whose ownership of such shares does not violate the Class I Preferred Ownership
Limit or other applicable limitation. Upon a sale of such shares by the trustee,
the interest of the charitable beneficiary will terminate, and the sales
proceeds would be paid, first, to the original intended transferee, to the
extent of the lesser of (a) such transferee's original purchase price (or the
original market value of such shares if purportedly acquired by gift or devise)
and (b) the price received by the trustee, and, second, any remainder to the
charitable beneficiary. In addition, shares of Class I Preferred Stock held in
such trust are purchasable by AIMCO for a 90-day period at a price equal to the
lesser of the price paid for the Class I Preferred Stock by the original
intended transferee (or the original market value of such shares if purportedly
acquired by gift or devise) and the market price for the Class I Preferred Stock
on the date that AIMCO determines to purchase the Class I Preferred Stock. The
90-day period commences on the date of the violative transfer or the date that
the AIMCO Board determines in good faith that a violative transfer or the date
that the AIMCO Board determines in good faith that a violative transfer has
occurred, whichever is later. All certificates representing shares of Class I
Preferred Stock bear a legend referring to the restrictions described above.

                       CERTAIN FEDERAL INCOME TAX MATTERS
    
 
   
     The following summary is a general discussion of certain federal income tax
consequences of the Offer that may be relevant to (i) Offerees who tender some
or all of their Units in exchange for OP Units pursuant to the Offer, (ii)
Offerees who tender some or all of their Units for cash pursuant to the Offer
and (iii) Offerees who do not tender any of their Units pursuant to the Offer.
This discussion is based upon the Internal Revenue Code of 1986 as amended ("the
Code"), Treasury Regulations, rulings issued by the IRS, and judicial decisions,
all in effect as of the date of this Offer and all of which are subject to
change, possibly retroactively. Such summary is based on the assumptions that
the AIMCO Operating Partnership and Your Partnership are classified and subject
to taxation for federal income tax purposes as partnerships rather than as
associations taxable as corporations and will be operated in accordance with
their respective organizational documents and partnership agreements. This
summary is for general information only and does not purport to discuss all
aspects of federal income taxation which may be important to a particular
Offeree in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
federal income tax purposes). This summary assumes that the Units held by
Offerees and OP Units received by Offerees in the Offer constitute capital
assets in the hands of such Offerees (generally, property held for investment).
No advance ruling has been or will be sought from the IRS regarding any matter
discussed in this Prospectus Supplement.
    
 
   
     THE FEDERAL INCOME TAX TREATMENT OF AN OFFEREE PARTICIPATING IN THE OFFER
DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF
COMPLEX PROVISIONS OF FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR
AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, EACH PROSPECTIVE OFFEREE SHOULD CONSULT
ITS TAX ADVISOR REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES
TO IT OF SELLING OR EXCHANGING UNITS PURSUANT TO THE OFFER OR OF A DECISION NOT
TO SELL OR EXCHANGE IN LIGHT OR THEIR SPECIFIC TAX SITUATION.
    
 
   
TAX CONSEQUENCES TO OFFEREES TENDERING UNITS SOLELY IN EXCHANGE FOR OP UNITS
    
 
   
     Except as described below, a tendering Offeree will not recognize gain or
loss for federal income tax purposes upon a transfer of Units solely in exchange
for OP Units. A tendering Offeree may recognize gain upon such exchange, where,
immediately prior to such exchange, the amount of liabilities of Your
Partnership allocable to the Units transferred by such Offeree exceeds the
amount of the AIMCO Operating Partnership liabilities allocated to the OP Units
received by the Offeree, as determined immediately after such exchange. In such
event, any such excess would be treated as a deemed distribution of cash from
the AIMCO Operating Partnership to the Offeree. Such deemed cash distribution
would be treated as a nontaxable return of capital to the extent of the
Offeree's adjusted tax basis in the OP Units received, and thereafter as a
taxable gain.
    
 
   
     The AIMCO Operating Partnership anticipates that, under most circumstances,
an Offeree would be allocated an amount of the AIMCO Operating Partnership
liabilities, as determined immediately after an exchange of Units pursuant to
the Offer, at least equal to the amount of liabilities of Your Partnership that
were allocable to such Units prior to such exchange. Accordingly, the AIMCO
Operating Partnership anticipates that most Offerees would not recognize gain or
loss as a result of an exchange of Units solely for OP Units pursuant to the
Offer.
    
 
   
     Offerees who are considering exchanging Units for OP Units pursuant to the
Offer are urged to read the description under the heading "Certain Federal
Income Tax Considerations -- the AIMCO Operating Partnership Tax
Considerations -- Tax Consequences Upon Contribution of Property to the AIMCO
Operating Partnership" in the accompanying Prospectus.

TAX CONSEQUENCES TO OFFEREES TENDERING UNITS IN EXCHANGE FOR OP UNITS AND CASH
    
 
   
     Generally, the exchange of Units for OP Units and cash will be treated, for
federal income tax purposes, as a partial taxable sale of such Units and as a
partial tax-free contribution of such Units to the AIMCO Operating Partnership.
The portion of the Units that will be treated as sold to the AIMCO Operating
Partnership will be equal to a fraction, the numerator of which will be the sum
of the cash received by the Offeree pursuant to the Offer plus the amount of
Your Partnership liabilities deemed transferred to the Offeree pursuant to the
Offer and the denominator of which is the fair market value of the aggregate
consideration received by the Offeree pursuant to the Offer (i.e., the sum of
the numerator of such fraction plus the fair market value of the OP Units
received by the Offeree pursuant to the Offer). The transfer by the Offeree of
the remaining portion of such Units will generally be treated as a tax-free
contribution. At the time of transfer, the adjusted tax basis of the transferred
Units is allocated between the portion of the Units deemed sold and the
remaining portion of the Units deemed contributed on the basis of each such
portion's respective fair market value.
    
 
   
     For purposes of the partial sale rules, the amount of Your Partnership
liabilities deemed transferred in the exchange will be equal to the lesser of
(i) the excess of Your Partnership liabilities allocable to such Offeree in
respect of the transferred Units immediately prior to the exchange over the
AIMCO Operating Partnership liabilities allocated to such Offeree as determined
immediately after the exchange or (ii) the product of (A) Your Partnership
liabilities allocable to such Offeree in respect of such transferred Units
immediately prior to the exchange and (B) a fraction, (x) the numerator of which
is the cash received and (y) the denominator of which is the excess of the fair
market value of the aggregate consideration received in the exchange over the
amount of Your Partnership liabilities allocable to such Offeree in respect of
the transferred Units immediately prior to the exchange.
    
 
   
     To the extent that the transfer of Units to the AIMCO Operating Partnership
is treated as a taxable sale, the Offeree transferring such Units will recognize
gain or loss in an amount equal to the difference between (i) the cash received
plus the amount of Your Partnership liabilities deemed transferred in the
exchange and (ii) the adjusted tax basis allocable to the portion of such Units
deemed sold. Thus, an Offeree's tax liability resulting from such sale of Units
could exceed the amount of cash received upon such sale. To the extent that the
transfer of Units in exchange for OP Units is treated as a tax-free contribution
to the AIMCO Operating Partnership, the Offeree will generally not recognize any
gain or loss for federal income tax purposes. A tendering Offeree may recognize
gain upon such exchange if the amount of Your Partnership liabilities allocable
to the tendering Offeree, as determined immediately prior to the exchange, in
respect of the portion of Units that are treated as being transferred in a
tax-free contribution exceeds the amount of the AIMCO Operating Partnership
liabilities allocated to such tendering Offeree as determined immediately after
the exchange. In this event, such excess would be treated as a deemed
distribution of cash from the AIMCO Operating Partnership to the Offeree. Such
deemed cash distribution would be treated as a nontaxable return of capital to
the extent of the Offeree's adjusted tax basis in the OP Units received, and
thereafter as a taxable gain. An Offeree will have a holding period in the OP
Units received pursuant to the portion of the exchange that is treated as a tax
free contribution that includes the holding period of its Units transferred in
exchange therefor.
    
 
   
TAX CONSEQUENCES TO OFFEREES TENDERING UNITS SOLELY IN EXCHANGE FOR CASH
    
 
   
     In general, an Offeree will recognize gain or loss on a sale of a Unit
pursuant to the Offer equal to the difference between (i) the Offeree's "amount
realized" on the sale and (ii) the Offeree's adjusted tax basis in the Units
sold by such Offeree. The "amount realized" with respect to a Unit will be equal
to the sum of the amount of cash received by the Offeree for the Unit sold by
such Offeree pursuant to the Offer (that is, the Offer Price) plus the amount of
the liabilities of Your Partnership allocable to such Unit (as determined under
Section 752 of the Code). Thus, an Offeree's tax liability resulting from such
sale of Units could exceed the amount of cash received upon such sale.

<PAGE>   58
 
   
ADJUSTED TAX BASIS
    
 
   
     In general, an Offeree had an initial tax basis in its Unit equal to the
cash investment in Your Partnership increased by such Offeree's share of Your
Partnership's liabilities at the time such Unit was acquired. An Offeree's
initial tax basis generally has been increased by (i) such Offeree's share of
Your Partnership income and gains and (ii) any increases in its share of
liabilities of Your Partnership, and has been decreased (but not below zero) by
(i) such Offeree's share of cash distributions from Your Partnership, (ii) any
decreases in such Offeree's share of liabilities of Your Partnership, (iii) such
Offeree's share of losses of Your Partnership, and (iv) such Offeree's share of
nondeductible expenditures of Your Partnership that are not chargeable to
capital. For purposes of determining an Offeree's adjusted tax basis in its
Units immediately prior to a disposition of such Units, its adjusted tax basis
in such Units will include its allocable share of Your Partnership's income,
gain or loss for the taxable year of disposition. If an Offeree's adjusted tax
basis is less than its share of Your Partnership's liabilities (e.g., as a
result of the effect of net loss allocations and/or distributions exceeding the
cost of its Unit), such Offeree's gain recognized pursuant to the Offer will
exceed the cash proceeds realized upon the sale of such Unit. The initial
adjusted tax basis of the OP Units received by an Offeree in exchange for its
Units pursuant to the Offer will be equal to (i) the sum of its adjusted tax
basis in such transferred Units plus any gain recognized in the exchange and
reduced by (ii) cash received or deemed received in the exchange.
    
 
   
CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER
    
 
   
     Except as described below, the gain or loss recognized by an Offeree on a
sale or exchange of a Unit pursuant to the Offer generally will be treated as a
capital gain or loss and will be treated as long-term capital gain or loss if
the tendering Offeree's holding period for the Unit exceeds one year. Long-term
capital gains recognized by individuals and certain other noncorporate taxpayers
generally will be subject to a maximum federal income tax rate of 20%. If the
amount realized with respect to a Unit attributable to an Offeree's share of
"unrealized receivables" of Your Partnership exceeds the basis attributable to
those assets, such excess will be treated as ordinary income. Among other
things, "unrealized receivables" include depreciation recapture with respect to
certain types of property. In addition, the maximum federal income tax rate
applicable to Offerees who are noncorporate taxpayers for net capital gains
attributable to the sale of depreciable real property (which may be determined
to include an interest in a partnership such as Your Partnership) held for more
than one year is currently 25% (rather than 20%) to the extent of previously
claimed depreciation deductions that would not be treated as "unrealized
receivables."
    
 
   
     A tendering Offeree will be allocated a share of Your Partnership's taxable
income or loss for the year of tender with respect to any Units sold or
exchanged. Thus, an Offeree will recognize ordinary income or loss in an amount
equal to Your Partnership's accreted income or loss allocable to such Unit.
Although such an Offeree will not receive a distribution with respect to any
accreted income, the Offer Price includes an amount that represents an estimate
by the AIMCO Operating Partnership of cash that may be available for
distribution to Offerees under the terms of The AIMCO Operating Partnership
Agreement. Such allocation and any cash distributed by Your Partnership to the
Offeree for that year will affect the Offeree's adjusted tax basis in its Unit
and, therefore, the amount of such Offeree's taxable gain or loss upon a sale of
a Unit pursuant to the Offer.
    
 
   
PASSIVE ACTIVITY LOSSES
    
 
   
     The passive activity loss rules of the Code limit the use of losses derived
from passive activities, which generally include investments in limited
partnership interests such as the Units. An individual, as well as certain other
types of investors, generally cannot use losses from passive activities to
offset nonpassive activity income received during the taxable year. Passive
activity losses that are disallowed for a particular tax year are "suspended"
and may be carried forward to offset passive activity income earned by the
investor in future taxable years. In addition, such suspended losses may be
claimed as a deduction, subject to other applicable limitations, upon a taxable
disposition of the investor's interest in such activity.
    
 
                                      S-54
<PAGE>   59
 
   
     Accordingly, if an Offeree's investment in Your Partnership is treated as a
passive activity, an Offeree may be able to shelter gain from the sale of its
Units pursuant to the Offer with such losses in the manner described below. An
Offeree that sells all or a portion of its Units pursuant to the Offer and
recognizes a gain on such sale will be entitled to use its current and
"suspended" passive activity losses (if any) from Your Partnership and other
passive sources to offset that gain. An Offeree that sells all or a portion of
its Units pursuant to the Offer and recognizes a loss on such sale will be
entitled to deduct that loss currently (subject to other applicable limitations)
against the sum of the Offeree's passive activity income from Your Partnership
for that year (if any) plus any passive activity income from other sources for
that year. If an Offeree sells all of its Units pursuant to the Offer, the
balance of any "suspended" losses that were not otherwise utilized against
passive activity income as described in the two preceding sentences will no
longer be suspended and will therefore be deductible (subject to any other
applicable limitations) by such Offeree against any other income of such Offeree
for that year, regardless of the character of that income. Accordingly, each
Offeree should consult its tax advisor concerning whether, and the extent to
which, the Offeree has available suspended passive activity losses from Your
Partnership or other investments that may be used to offset gain from the sale
of its Units pursuant to the Offer.
    
 
   
FOREIGN OFFEREES
    
 
   
     Gain recognized by a foreign Offeree on a transfer of a Unit for cash, OP
Units, or a combination thereof, pursuant to the Offer will be subject to
federal income tax under the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). In such event, under the FIRPTA provisions of the Code, the AIMCO
Operating Partnership will be required to deduct and withhold 10% of the amount
realized by a foreign Offeree on the disposition. Amounts would be creditable
against a foreign Offeree's federal income tax liability and, if in excess
thereof, a refund could be obtained from the Internal Revenue Service by filing
a U.S. income tax return. See the Instructions to the Letter of Transmittal.
    
 
   
     EACH HOLDER OF UNITS SHOULD CONSULT SUCH HOLDER'S TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES APPLICABLE TO SUCH HOLDER AS A RESULT OF A SALE OR
EXCHANGE OF UNITS PURSUANT TO THE OFFER.
    
 
   
                               VALUATION OF UNITS
    
 
   
     We determined the Offer Price by estimating the proceeds that you would
receive if Your Partnership were liquidated. For this purpose, we estimated the
value of the property owned by Your Partnership using the direct capitalization
method. This method involves applying a capitalization rate to Your
Partnership's annual forecasted net operating income. However, there are a
number of available methods to value real estate, each of which requires
judgments about certain variables. We used our best judgment for these
variables, but our valuation is ultimately an estimate. The proceeds that you
would receive if you sold your Units to someone else or if Your Partnership were
actually liquidated might be higher or lower than our Offer Price. We determined
our offer price as follows:
    
 
   
     - First, we calculated the value of the property owned by Your Partnership
       using the direct capitalization method. We applied a capitalization rate
       of      % to the property's forecasted annual net operating income of
       $          for the period from January 1, 1998 to December 31, 1998 to
       derive a gross property value of $          . We selected a
       capitalization rate of      %, based on our experience in valuing similar
       properties. The lower the capitalization rate applied to a property's
       income, the higher its value. We considered local market sales
       information for comparable properties, estimated actual capitalization
       rates (net operating income less capital reserves divided by sales price)
       and then evaluated Your Partnership Property in light of its relative
       competitive position, taking into account property location, occupancy
       rate, overall property condition and other relevant factors. The AIMCO
       Operating Partnership believes that arms'-length purchasers would base
       their purchase offers on capitalization rates comparable to those used by
       us, however there is no single correct capitalization rate and others
       might use different rates. We added to this gross valuation capital
       expenditures of $          to derive a purchase price for the property of
       $          .
    
 
                                      S-55
<PAGE>   60
 
   
     - Second, we calculated the value of the equity of Your Partnership by
       adding the property value calculated in the first step and the value, as
       of June 30, 1998, of the assets of Your Partnership, deducting
       liabilities of Your Partnership, including mortgage debt and debt owed by
       Your Partnership to its general partner or its affiliates after
       consideration of any applicable subordination provisions affecting
       payment of such debt. We deducted from this value any taxes and certain
       other costs including initial capital expenditures and deferred
       maintenance to derive a net equity value for Your Partnership of
       $          .
    
 
   
     - Third, using this net equity value, we determined the proceeds that would
       be paid to holders of Units in the event of a liquidation of Your
       Partnership, based on the terms of Your Partnership Agreement. Our cash
       Offer Price represents the per Unit liquidation proceeds determined in
       this manner.
    
 
   
     - In order to determine the number of Preferred OP Units we are offering
       you, we divided the per Unit liquidation proceeds by a price of $100 per
       unit for the Preferred OP Units.
    
 
   
     - In order to determine the number of Common OP Units we are offering you,
       we divided the per Unit liquidation proceeds by a price of
       $               per Unit for the Common OP Units. We determined the value
       of the Common OP Units based on the trading price of AIMCO's Class A
       Common Stock. The last reported closing sales price of AIMCO's Class A
       Common Stock on the New York Stock Exchange was $33 3/4 on September 16,
       1998.

                             FAIRNESS OF THE OFFER
    
 
   
POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT TO THE OFFER;
FAIRNESS
    
 
   
     The general partner of Your Partnership is owned by the AIMCO Operating
Partnership. Therefore, the general partner of Your Partnership makes no
recommendation to any Offeree to tender or to refrain from tendering his or her
Units. The AIMCO Operating Partnership has retained Stanger to conduct an
analysis of the Offer and to render an opinion to the Company as to the fairness
to Offerees of the Offer Price from a financial point of view. Stanger is
unaffiliated with the Company and unaffiliated with Your Partnership. Stanger is
one of the leaders in the field of analyzing and evaluating complex real estate
transactions. However, much of the information used by Stanger in forming its
fairness opinion was provided by either the Company or Your Partnership. We
believe the information provided to Stanger is accurate in all material
respects. See "Stanger Analysis." No person has been authorized to make any
recommendation on behalf of the general partner of Your Partnership with respect
to the Offer. Each Offeree must make his or her own decision whether to tender
based upon a number of factors, including the Offeree's own financial needs,
other financial opportunities and tax position.
    
 
   
     The terms of the Offer, and in particular the exchange ratios, have been
established by the AIMCO Operating Partnership and are not the result of
arms-length negotiations between the AIMCO Operating Partnership and Your
Partnership. In evaluating the fairness of the Offer, the general partner of
Your Partnership and the AIMCO Operating Partnership have considered the
following factors and information:
    
 
   
        1. The opportunity for each Offeree to make an individual decision on
     whether to tender Units in the Offer and that the Offer allows each Offeree
     to continue to hold his Units.
    
 
   
        2. The estimated value of Your Partnership Property has been determined
     based on a method believed to be used by buyers of such assets in the
     market.
    
 
   
        3. An analysis of the possible alternatives including liquidation and
     continuation without the option of the Offer. See "Background and Reasons
     for the Offer -- Alternatives Considered."
    
 
   
        4. An evaluation of the financial condition and results of operations of
     Your Partnership and the AIMCO Operating Partnership and their anticipated
     level of operating results. The Offer is not expected to have a material
     effect on Your Partnership's financial condition or results of operations.
    
 
   
        5. The method of determining the exchange ratios which are designed to
     provide an Offeree with OP Units or cash which is generally financially
     equivalent to his or her interest in Your Partnership, adjusted to reflect
     the expenses of the Offer. See "Valuation of Units."
    
 
   
        6. The opinion of Stanger, a third party expert, that the Offer Price is
     fair to holders of Units from a financial point of view. See "Stanger
     Analysis"
    
 
   
        7. The fact that the Units are illiquid and the Offer provides holders
     of Units with liquidity.
    
 
   
        8. The fact that the Offer provides holders of Units with the
     opportunity to receive both cash and OP Units together.
    
 
   
        9. The fact that the Offer provides holders of Units with the
     opportunity to defer taxes.
    
 
   
        10. An evaluation of the market price of the Class A Common Stock and
     the limited information on prices at which Common OP Units and Units are
     transferred. See "Your Partnership -- Distributions and Transfers of
     Units." No assurance can be given that the Class A Common Stock will
     continue to trade at its current price.
    
 
   
        11. The estimated Unit value based on estimated Partnership Property
     value is        . The general partner of Your Partnership has no present
     intention to liquidate Your Partnership or to sell or finance Your
     Partnership Property. See "Background and Reasons for the Offer".
    
 
   
          12. Based on anticipated annualized distributions of $     with
     respect to the Preferred OP Units, current annualized distributions with
     respect to the Common OP Units and the estimated 1998
    
 
                                      S-57
<PAGE>   62
 
   
     distributions of $0 with respect to the Units, distributions with respect
     to the Preferred OP Units and Common OP Units to be received in the Offer
     are expected to be greater, immediately following the Offer, than the
     distributions with respect to Units. See "Comparison of Ownership of Your
     Units and AIMCO OP Units -- Distributions."
    
 
   
     In evaluating these factors, the general partner of Your Partnership and
the AIMCO Operating Partnership did not quantify or otherwise attach particular
weight to any of them. The general partner of Your Partnership has a conflict of
interest with respect to the Offer's completion. See "Conflicts of Interest."
    
 
   
FAIRNESS TO OFFEREES EXCHANGING UNITS
    
 
   
     The general partner of Your Partnership makes no recommendation to any
Offeree to tender or to refrain from tendering Units. The terms of the Offer,
and in particular the exchange ratios, have been established by the AIMCO
Operating Partnership and are not the result of arms-length negotiations between
the AIMCO Operating Partnership and Your Partnership. See "Conflicts of
Interest." The general partner of Your Partnership and the AIMCO Operating
Partnership believe that the valuation method described in "Valuation of Units"
provides a meaningful indication of value for residential apartment properties
although there are other ways to value real estate. A liquidation in the future
might generate a higher price for holders of Units.
    
 
   
     The future value of the OP Units received in the Offer will depend on some
of the same factors that will affect the value of the Units, primarily the
condition of the real estate markets. However, Offerees who become holders of OP
Units will be able to liquidate their investment only by tendering their OP
Units for redemption after a one-year holding period or by selling their OP
Units, which may preclude them from realizing the full value of their
investment.
    
 
   
FAIRNESS TO NON-TENDERING OFFEREES
    
 
   
     The general partner of Your Partnership makes no recommendation to any
Offeree to tender or to refrain from tendering Units. If an Offeree chooses not
to tender any Units, his interest in Your Partnership remains effectively
unchanged. Only the identity of the other limited partners of Your Partnership
will change such that the AIMCO Operating Partnership will own a larger share of
the limited partnership interests in Your Partnership than it did before the
Offer. If the AIMCO Operating Partnership acquires a substantial number of Units
pursuant to the Offer, the Company may be in a position to influence voting
decisions with respect to Your Partnership. The Company has no present intention
to liquidate, sell, finance or refinance the Partnership Property within any
specified time period.
    
 
   
COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION
    
 
   
  General
    
 
   
     To assist holders of Units in evaluating the Offer, the general partner of
Your Partnership has attempted to compare the cash Offer Price against: (a) the
prices at which the Units have been sold in the illiquid secondary market and
(b) estimates of the value of the Units on a liquidation basis. The estimated
value of Your Partnership on a going concern basis could result in proceeds on a
per unit basis which could be higher or lower than the Offer Price. The general
partner of Your Partnership believes that analyzing the alternatives in terms of
estimated value, established based upon currently available data and, where
appropriate, reasonable assumptions made in good faith, establishes a reasonable
framework for comparing alternatives. Since the value of the consideration for
alternatives to the Offer is dependent upon varying market conditions, no
assurance can be given that the estimated values reflect the range of possible
values. See "Valuation of Units."
    
 
   
     The results of these comparative analyses are summarized in the following
chart. Offerees should bear in mind that the estimated values assigned to the
alternate forms of consideration are based on a variety of assumptions that have
been made by the general partner of Your Partnership. These assumptions relate,
among other things to: projections as to the future income, expenses, cash flow
and other significant financial matters of Your Partnership; the capitalization
rates that will be used by prospective buyers when Your
    
 
                                      S-58

     Partnership's assets are liquidated; and appropriate discount rates to
apply to expected cash flows in computing the present value of the cash flows
that may be received with respect to Units.
    
 
   
     In addition, these estimates are based upon certain information available
to the general partner of Your Partnership at the time the estimates were
computed, and no assurance can be given that the same conditions analyzed by it
in arriving at the estimates of value would exist at the time of the Offer. The
assumptions used have been determined by the general partner of Your Partnership
in good faith, and, where appropriate, are based upon current and historical
information regarding Your Partnership and current real estate markets, and have
been highlighted below to the extent critical to the conclusions of the general
partner of Your Partnership. The estimated values in the following chart are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Actual results may vary from those set forth
below based on numerous factors, including interest rate fluctuations, tax law
changes, supply and demand for similar apartment properties, the manner in which
Your Partnership Property is sold and changes in availability of capital to
finance acquisitions of apartment properties.

</TABLE>
    
 
   
  Prices on Secondary Market
    
 
   
     There is no active market for the Units. The general partner of Your
Partnership is unaware of any secondary market activity in the Units. However,
we have made two prior tender offers for Units. In the first offer, made in
August 1997, we offered to acquire all Units of Your Partnership at a price of
$2,648 per Unit in cash. In June, 1998, we offered to acquire all Units of Your
Partnership at a price of $21,668 per Unit in cash.
    
 
   
  Estimated Liquidation Value
    
 
   
     Liquidation value is a measure of the price at which the assets of Your
Partnership would sell if disposed of in an arms'-length transaction between a
willing buyer and Your Partnership, each having access to relevant information
regarding the historical revenues and expenses of the business. The general
partner of Your Partnership estimated the liquidation value of Units using the
same direct capitalization method and assumptions as we did in valuing the Units
for the cash Offer Price. See "Valuation of Units." The only significant
difference is that the general partner of Your Partnership assumed liquidation
would involve additional selling expenses of   % of the sale proceeds. The
general partner of Your Partnership believes this is a normal and customary cost
of property sales. The liquidation analysis also assumed that the Partnership
Property was sold to an independent third-party buyer at the current property
value and that other balance sheet assets (excluding amortizing assets) and
liabilities of Your Partnership were sold at their book value, and that the net
proceeds of sale were allocated between the general partners and Offerees in
accordance with Your Partnership Agreement.
    
 
   
     The liquidation analysis assumes that the assets of Your Partnership are
sold in a single transaction. Should the assets be liquidated over time, even at
prices equal to those projected, distributions to limited partners from cash
flow from operations might be reduced because Your Partnership's relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.

ALLOCATION OF CONSIDERATION
    
 
   
     The Company has allocated the consideration for the Offer to the Offerees
in accordance with the liquidation provisions of Your Partnership Agreement. The
general partner of Your Partnership owns a 5.50% stake in Your Partnership, the
special limited partners own a 19.50% stake in Your Partnership, and the
Offerees own a 75.00% stake in Your Partnership according to Your Partnership
Agreement. The Offerees have certain liquidation preferences under Your
Partnership Agreement such that the general partner and the special limited
partners will receive liquidation proceeds only if certain performance
thresholds are met. Since such thresholds have not been met, 100% of the
consideration for the Offer is being allocated to the Offerees. See "Valuation
of Units."
    
 
   
                                STANGER ANALYSIS
    
 
   
     Stanger, an independent investment banking firm, was engaged by the Company
to conduct an analysis and to render an opinion (the "Fairness Opinion") as to
whether the cash component of the Offer Price for the Units is fair, from a
financial point of view, to the Offerees. The Company selected Stanger because
of its experience in providing similar services to other parties in connection
with real estate merger and sale transactions and Stanger's experience and
reputation in connection with real estate partnerships and real estate assets.
No other investment banking firm was engaged to provide, or has provided, any
report, analysis or opinion relating to the fairness of the Offer.
    
 
   
     Stanger has advised the Company that, subject to the assumptions,
limitations and qualifications contained in its Fairness Opinion, the Offer
Price for the Units is fair, from a financial point of view, to the Offerees.
The Offer Price was determined solely by the Company, and Stanger did not, and
was not requested to, make any recommendations as to the form or amount of
consideration to be paid to the Offerees in connection with the Offer.
    
 
   
     The full text of the Fairness Opinion, which contains a description of the
matters considered and the assumptions, limitations and qualifications made, is
set forth as Appendix B-1 hereto and should be read in its entirety. The summary
set forth herein does not purport to be a complete description of the review
performed by Stanger in rendering the Fairness Opinion. Arriving at a fairness
opinion is a complex process not necessarily susceptible to partial analysis or
amenable to summary description.
    
 
   
     The Company imposed no conditions or limitations on the scope of Stanger's
investigation or with respect to the methods and procedures to be followed in
arriving at the fairness opinion. See "-- Fairness Opinion -- Assumptions,
Limitations and Qualifications." AIMCO has agreed to indemnify Stanger against
certain liabilities arising out of Stanger's engagement to prepare and deliver
the Fairness Opinion.
    
 
   
EXPERIENCE OF STANGER

connection with real estate partnerships, real estate assets and mergers and
acquisitions.

SUMMARY OF REVIEWS
    
 
   
     The following is a summary of the material reviews conducted by Stanger in
connection with and in support of its Fairness Opinion. The summary of the
opinion and reviews of Stanger set forth in this Prospectus Supplement is
qualified in its entirety by reference to the full text of such opinion.
    
 
   
     Property Evaluation. In preparing its Fairness Opinion, Stanger performed a
site inspection of Your Partnership Property during September 1998. In the
course of the site visit, the physical facilities of Your Partnership Property
were observed, current rental and occupancy information was obtained, current
local market conditions were reviewed, similar competing properties were
identified, and local property management personnel were interviewed concerning
Your Partnership Property and local market conditions. Stanger also reviewed and
relied upon information provided by Your Partnership and the Company, including,
but not limited to, financial schedules of historical and current rental rates,
occupancies, income, expenses, reserve requirements, cash flow and related
financial information; property descriptive information including unit mix; and
information relating to the condition of the property, including any deferred
maintenance, capital budgets, status of ongoing or newly planned property
additions, reconfigurations, improvements and other factors affecting the
physical condition of the property improvements.
    
 
   
     Stanger also reviewed historical operating statements for Your Partnership
Property for 1996, 1997, and for the six month period ending June 30, 1998, the
operating budget for 1998 as prepared by Your Partnership and discussed with
management the current and anticipated operating results of Your Partnership
Property.
    
 
   
     In addition, Stanger interviewed management personnel of Your Partnership
and the Company. Such interviews included discussions of conditions in the local
market, economic and development trends affecting Your Partnership Property,
historical and budgeted operating revenues and expenses and occupancies and the
physical condition of Your Partnership Property (including any deferred
maintenance and other factors affecting the physical condition of the
improvements), projected capital expenditures and building improvements, the
terms of existing debt, encumbering Your Partnership Property, and expectations
of management regarding operating results of Your Partnership Property.

     Stanger also reviewed the acquisition criteria used by owners and investors
in the type of real estate owned by Your Partnership, utilizing available
published information and information derived from interviews conducted by
Stanger with various real estate owners and investors.
    
 
   
     Review of Partnership Liquidation Analysis. Stanger reviewed an analysis
prepared by the management of Your Partnership of the estimated liquidation
values of Units utilizing estimates prepared by Your Partnership of expenses
associated with such a liquidation. The liquidation analysis assumed that the
Partnership Property was sold to an independent third-party buyer at the current
property value estimated by the management of Your Partnership and that normal
and customary costs of property sale were incurred, that other balance sheet
assets (excluding amortizing assets) and liabilities of Your Partnership were
sold at their book value, and that the net proceeds of sale were allocated
between the General Partners and Offerees in accordance with Your Partnership
Agreement.
    
 
   
CONCLUSIONS
    
 
   
     Stanger concluded, based upon its analysis of the foregoing and the
assumptions, qualifications and limitations stated below, as of the date of the
Fairness Opinion, that the Offer Price to be paid for the Units in connection
with the Offer is fair to the Offerees from a financial point of view.
    
 
   
ASSUMPTIONS, LIMITATIONS AND QUALIFICATIONS
    
 
   
     In rendering the Fairness Opinion, Stanger relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and data, and all other reports and information contained in this
Prospectus Supplement or that were provided, made available, or otherwise
communicated to Stanger by Your Partnership, the Company, or the management of
the Partnership Property. Stanger has not performed an independent appraisal,
engineering study or environmental study of the assets and liabilities of Your
Partnership. Stanger relied upon the representations of Your Partnership and the
Company concerning, among other things, any environmental liabilities, deferred
maintenance and estimated capital expenditure and replacement reserve
requirements, the determination and valuation of non-real estate assets and
liabilities of Your Partnership, the allocation of Your Partnership's net values
between the general partner, special limited partner and limited partners of
Your Partnership, the terms and conditions of any debt encumbering the
Partnership Property, and the transaction costs and fees associated with a sale
of the Property. Stanger also relied upon the assurance of Your Partnership, the
Company, and the management of the Partnership Property that any financial
statements, budgets, pro forma statements, projections, capital expenditure
estimates, debt, value estimates and other information contained in this
Prospectus Supplement or provided or communicated to Stanger were reasonably
prepared and adjusted on bases consistent with actual historical experience, are
consistent with the terms of Your Partnership Agreement, and reflect the best
currently available estimates and good faith judgments; that no material changes
have occurred in the value of the Partnership Property or other balance sheet
assets and liabilities or other information reviewed between the date of such
information provided and the date of the Fairness Opinion; that Your
Partnership, the Company, and the management of the Partnership Property are not
aware of any information or facts that would cause the information supplied to
Stanger to be incomplete or misleading; that the highest and best use of the
Partnership Property is as improved; and that all calculations were made in
accordance with the terms of Your Partnership Agreement.
    
 
   
     Stanger was not requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price; (ii) make any recommendation
to Your Partnership or its partners with respect to whether to accept or reject
the proposed Offer or whether to accept the cash, Preferred OP Units or Common
OP Units if the Offer is accepted; (iii) solicit any third party indications of
interest in acquiring the assets of Your Partnership or all or any part of Your
Partnership; or (iv) express any opinion as to (a) the tax consequences of the
Offer to the Offerees, (b) the terms of Your Partnership Agreement or the terms
of any agreements or contracts between Your Partnership or the Company; (c) the
Company's or the general partner's business decision to effect the Offer, or
alternatives to the Offer, (d) the amount or allocation of expenses relating to
the Offer between the Company and Your Partnership or tendering Offerees; (e)
the relative value of the cash, Preferred OP Units or Common OP Units to be
issued in connection with the Offer;

     and (f) any adjustments made to determine the Offer Price and the net
amounts distributable to the Offerees, including but not limited to, balance
sheet adjustments to reflect Your Partnership's estimate of the value of current
net working capital balances, reserve accounts, and liabilities, and adjustments
to the Offer Price for distributions made by Your Partnership subsequent to the
date of the initial Offer.
    
 
   
     Stanger is not expressing any opinion as to the fairness of any terms of
the Offer other than the cash component of the Offer Price for the Units.
Stanger's opinion is based on business, economic, real estate and capital
market, and other conditions as of the date of its analysis and addresses the
Offer in the context of information available as of the date of its analysis.
Events occurring after such date and before the closing of the proposed Offer
could affect the Partnership Property or the assumptions used in preparing the
Fairness Opinion. Stanger has no obligation to update the Fairness Opinion on
the basis of subsequent events.
    
 
   
     In connection with preparing the Fairness Opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the report set forth in Appendix
B-1.

                             CONFLICTS OF INTEREST
    
 
   
CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER
    
 
   
     The general partner of Your Partnership became a subsidiary of the Company
in June 1997, when the Company acquired NHP. Accordingly, the general partner of
Your Partnership is an affiliate of the AIMCO Operating Partnership and,
therefore, has substantial conflicts of interest with respect to the Offer. The
general partner of Your Partnership has a fiduciary obligation to obtain a fair
Offer Price for you, even as a subsidiary of the Company. It also has a duty to
remove the Property Manager, under certain circumstances, even though the
Property Manager is also an affiliate of the Company. The conflicts of interest
include the fact that a decision of the Offerees to remove, for any reason, the
general partner of Your Partnership from its current position as a general
partner of Your Partnership would result in a decrease or elimination of the
substantial management fees paid to an affiliate of the general partner of Your
Partnership for managing Your Partnership Property owned by Your Partnership.
The general partner of Your Partnership makes no recommendation to any Offeree
as to whether to tender or to refrain from tendering Units. Such conflicts of
interest in connection with the Offer and the operation of the Company differ
from those conflicts of interest that currently exist for Your Partnership. See
"Risk Factors -- Risks to Offerees Who Tender Their Units in the
Offer -- Conflicts of Interest with Respect to the Offer."
    
 
   
CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP
    
 
   
     We own the general partner of Your Partnership and a 95% non-voting
interest in the manager of Your Partnership Property, which received management
fees of $427,385 in 1996, $437,571 in 1997 and $215,708 for the first six months
of 1998. The AIMCO Operating Partnership has no current intention of changing
the fee structure for the manager of Your Partnership Property. The general
partner of Your Partnership receives a fee of $2,083 per month from Your
Partnership.
    
 
   
COMPETITION AMONG PROPERTIES
    
 
   
     Because the Company and Your Partnership both invest in apartment
properties, these properties may compete with one another for tenants. The
Company's policy is to limit its management to properties which do not compete
with one another. Furthermore, you should bear in mind that the Company
anticipates acquiring properties in general market areas where Your Partnership
Property is managed by Your Partnership. It is believed that this concentration
of properties in a general market area will facilitate overall operations
through collective advertising efforts and other operational efficiencies. In
managing the Company's properties, the AIMCO Operating Partnership will attempt
to reduce such conflicts between competing properties by referring prospective
customers to the property considered to be most conveniently located for the
customer's needs.
    
 
   
FEATURES DISCOURAGING POTENTIAL TAKEOVERS
    
 
   
     Certain provisions of the Company's governing documents, as well as
statutory provisions under certain state laws, could be used by the Company's
management to delay, discourage or thwart efforts of third parties to acquire
control of, or a significant equity interest in, the Company. See "Comparison of
Your Partnership and the AIMCO Operating Partnership."
    
 
   
FUTURE EXCHANGE OFFERS
    
 
   
     If the results of operations were to improve for Your Partnership under the
Company's management, the Company might be required to pay a higher price for
any future exchange offers it may make for Units of Your Partnership. We
conducted two prior tender offers for Units of Your Partnership. In August, 1997
we acquired a 0.7576% interest in Your Partnership through the first tender
offer. In June 1998, we acquired an additional 0.3788% interest in Your
Partnership through the second tender offer. Although we have no current plans
to conduct future exchange offers for your Units, our plans may change based on
future circumstances. Any such future offers that we might make could be for
consideration that is more or less than the consideration we are currently
offering.

                                YOUR PARTNERSHIP
    
 
   
GENERAL
    
 
   
     Your Partnership is a Florida limited partnership which raised
approximately $7,400,000 in 1988 through a private offering. The promoter for
the private offering of Your Partnership was Stephen A. Goldberg. NHP acquired
Your Partnership in July 1996. The Company acquired NHP in June 1997. Your
Partnership is in the business of owning and managing residential housing.
Currently, Your Partnership owns and manages the single property described
below. Your Partnership has no employees.
    
 
   
YOUR PARTNERSHIP AND ITS PROPERTY
    
 
   
     Your Partnership was formed on August 26, 1988 for the purpose of owning
and operating an assisted living apartment property located in Boca Raton,
Florida, known as "Casa Del Mar." Your Partnership Property consists of 214
apartment units: 141 one bedroom units with an average size of 675 square feet
and 73 two bedroom units with an average size of 1,009 square feet. Assisted
living services are provided in 60 units and 154 units provide independent
living. The property sits on 12 acres. The apartment units included in the
Partnership Property average approximately 789 square feet. Approximately 65.90%
of the apartments are efficiency and one-bedroom apartments, and 34.10% are
two-bedroom apartments. Your Partnership Property had an average occupancy rate
of approximately 96% in 1997 and 92% during the first six months of 1998.
    
 
   
     Your Partnership Property provides residents with a number of amenities and
services. Each apartment is equipped with a washer and dryer. There are
emergency pull cords in every apartment and there is a courtesy security patrol
from 5pm - 8am every day. Your Partnership Property provides transportation to
doctor's appointments within a 5-mile radius of the property. Group bus trips to
banks, shopping, and entertainment activities take place on pre-announced
schedules. Meal service is available three times per day in addition to a
snack/sandwich shop. Five course dinners are offered nightly with fourteen
entree choices. Activities include billiards, fitness programs with a certified
trainer, movies, swimming pool, spa, movies, lectures and live entertainment in
the property's auditorium. Preferred Home Health, an affiliate of AIMCO, is a
home health care agency with an office on site.
    
 
   
PROPERTY MANAGEMENT
    
 
   
     Since 1997, Your Partnership Property has been managed by an affiliate of
the Company. Pursuant to the management agreement between the Property Manager
and Your Partnership, the Property Manager operates Your Partnership Property,
establishes rental policies and rates and directs marketing activities. The
Property Manager also is responsible for maintenance, the purchase of equipment
and supplies, and the selection and engagement of all vendors, suppliers and
independent contractors. The management fee which Your Partnership paid the
Property Manager during 1996, 1997 and the first six months of 1998 were
$427,385, $437,571 and $215,708, respectively.
    
 
   
     The manager of the Partnership Property is an affiliate of the general
partner of Your Partnership and of the Company.
    
 
   
INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS
    
 
   
     Under Your Partnership Agreement, Your Partnership is permitted to raise
new capital and reinvest cash in new properties. Your Partnership will terminate
on December 31, 2038 unless earlier dissolved. Your Partnership has no present
intention to liquidate, sell, finance or refinance Your Partnership Property
within any specified time period.
    
 
   
     Generally, Your Partnership is authorized to acquire, develop, improve, own
and operate Your Partnership Property as an investment and for income producing
purposes. The investment portfolio of Your Partnership is limited to the assets
acquired with the initial equity raised through the sale of Units to the limited
partners of Your Partnership or the assets initially contributed to Your
Partnership by the limited
    
 
                                      S-74
<PAGE>   79
 
   
     partners, as well as the debt financing obtained by Your Partnership within
the established borrowing restrictions. Your Partnership may raise new equity
only in narrow circumstances and consequently is quite limited in its ability to
expand its investment portfolio.
    
 
   
     An investment in Your Partnership is a finite life investment, with the
partners to receive regular cash distributions out of Your Partnership's
distributable cash flow, if available, and to receive cash distributions upon
liquidation of Your Partnership's real estate investments, if available.
    
 
   
CAPITAL REPLACEMENT
    
 
   
     Your Partnership maintains an ongoing program of capital improvements,
replacements and renovations, including roof replacements, kitchen and bath
renovations, balcony repairs (where applicable), replacement of various building
systems and other replacements and renovations in the ordinary course of
business. All capital improvement and renovation costs are expected to be paid
from operating cash flows, cash reserves, or from short-term or long-term
borrowings. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations of Your Partnership."
    
 
   
BORROWING POLICIES
    
 
   
     Your Partnership Agreement. Your Partnership Agreement allows Your
Partnership to incur debt. As of June 30, 1998, Your Partnership had a current
mortgage note outstanding of $13,800,862, payable to Mellon Bank MD, which bears
interest at the rate of 8.12%. The mortgage debt is due in August 2005. In
addition, Your Partnership had borrowed $1,714,490 (including accrued interest)
from an unrelated party on an unsecured basis as of June 30, 1998. The majority
of these borrowings bear interest at 9% and are due July 2006. Your Partnership
Agreement also allows the general partner of Your Partnership to lend funds to
Your Partnership. As of June 30, 1998, the general partner of Your Partnership
had outstanding loans (including accrued and unpaid interest) of $5,906,796 to
Your Partnership, which generally bear interest at a rate of 9% and mature in
July 2006.
    
 
   
COMPETITION
    
 
   
     There are other residential properties within the market area of the
Partnership Property. The number of competitive properties in such an area could
have a material effect on the rental market for the apartments at a property and
the rents that may be charged for such apartments.
    
 
   
LEGAL PROCEEDINGS
    
 
   
     Your Partnership is party to a variety of legal proceedings related to its
ownership of the Partnership Property and management and leasing business,
respectively, arising in the ordinary course of the business, which are not
expected to have a material adverse effect on Your Partnership.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
    
   
OF YOUR PARTNERSHIP
    
 
   
  Overview
    
 
   
     The following discussion and analysis of the results of operations and
financial condition of Your Partnership should be read in conjunction with the
audited and unaudited financial statements included elsewhere herein.
    
 
   
  Results of Operations
    
 
   
     Comparison of the Six Months Ended June 30, 1998 to the Six Months Ended
June 30, 1997
    
 
   
     Net Loss
    
 
   
     Your Partnership recognized net loss of $242,115 for the six months ended
June 30, 1998, compared to net loss of $89,887 for the six months ended June 30,
1997. The increased net loss of $152,228, or 169%, was primarily due to
decreased rental and other property revenues and increased operating expenses
and general administrative expenses discussed below.
    
 
   
     Revenues
    
 
   
     Rental and other property revenues of Your Partnership totaled $3,633,623
for the six months ended June 30, 1998, compared to $3,699,929 for the six
months ended June 30, 1997, a decrease of $66,306, or 2%. This decline was
related to higher vacancy rates during 1998 than 1997.
    
 
   
     Expenses
    
 
   
     Operating expenses of Your Partnership, consisting of utilities (net of
reimbursements received from tenants), contract services, payroll, turnover
costs, repairs and maintenance, advertising and marketing, property taxes,
insurance and health center expenses, totaled $2,156,586 for the six months
ended June 30, 1998, compared to $2,034,533 for the six months ended June 30,
1997, an increase of $122,053, or 6%. This increase was due to higher payroll
and related expenses, repairs and maintenance costs and advertising costs, which
were somewhat offset by reduced health center expenses, during 1998. 401(k)
eligibility requirements changed when the Company purchased the general partner
and the Property Manager from NHP in 1997. As a result, the number of eligible
employees increased resulting in higher payroll expenses. During 1998, a new
advertising agency was hired to develop a marketing strategy to improve
occupancy. 1998 repairs and maintenance increased over the prior period due to
repairs related to the kitchen located on the premises, as well as cost
associated with the turnover of vacant units. In March 1998, the Company
contracted with a new food service to provide a lower cost food service program.
As a result, health center expenses decreased in 1998 by $44,531. Your
Partnership's management expenses totaled $215,708 for the six months ended June
30, 1998, compared to $222,929 for the six months ended June 30, 1997, a
decrease of $7,221, or 3%. Management fees are based on 6% of collected
revenues, which decreased in 1998.
    
 
   
     General and Administrative Expenses
    
 
   
     General and administrative expenses decreased to $138,306 for the six
months ended June 30, 1998 from $177,149 for the six months ended June 30, 1997,
a decrease of $38,843, or 22%. This was primarily due to recruiting expense of
$27,117 incurred in 1997, but not in 1998.
    
 
   
     Interest Expense
    
 
   
     Interest expense totaled $905,975 for the six months ended June 30, 1998,
compared to $894,580 for the six months ended June 30, 1997, an increase of
$11,395 or 1%.

     Interest Income
    
 
   
     Interest income totaled $4,274 for the six months ended June 30, 1998,
compared to $2,643 for the six months ended June 30, 1997, an increase of $1,631
or 62%. This increase was related to interest income earned on operating funds.
    
 
   
     Comparison of the year ended December 31, 1997 to the year ended December
31, 1996
    
 
   
     Net Loss
    
 
   
     Your Partnership recognized loss before extraordinary item of $352,461 for
the year ended December 31, 1997, compared to loss before extraordinary item of
$748,950 for the year ended December 31, 1996. The decrease in loss before
extraordinary item of $396,489, or 53%, was primarily due to increased rental
and other property revenues in 1997. Your Partnership recognized net loss of
$352,461 for the year December 31, 1997, compared to net loss of $398,693 for
the year ended December 31, 1996, a decrease in net loss of $46,232, or 12%. The
reasons for these variances are discussed below.
    
 
   
     Revenues
    
 
   
     Rental and other property revenues of Your Partnership totaled $7,329,537
for the year ended December 31, 1997, compared to $6,961,529 for the year ended
December 31, 1996, an increase of $368,008, or 5%. This increase was primarily a
result of an increase in 1997 average rental rates.
    
 
   
     Expenses
    
 
   
     Operating expenses of Your Partnership, consisting of, utilities (net of
reimbursement received from tenants), contract services, payroll, turnover
costs, repairs and maintenance, advertising and marketing, property taxes,
insurance and health center expenses, totaled $4,264,030 for the year ended
December 31, 1997, compared to $4,112,001 for the year ended December 31, 1996,
an increase of $152,029, or 4%. 401(k) eligibility requirements changed when NHP
purchased the general partner of Your Partnership and assumed management of Your
Partnership in July 1996. As a result, the number of eligible employees
increased resulting in increased payroll expenses of $57,017. An accelerated
marketing strategy was implemented to reduce vacancies in late 1997, resulting
in an increase in advertising expenses of $103,366. Your Partnership management
expenses totaled $437,571 for the year December 31, 1997, compared to $427,385
for the year ended December 31, 1996, an increase of $10,186, or 2%.
Depreciation and amortization totaled $930,683 in 1997 compared to $1,078,157 in
1996, a decrease of $147,474 or 14%. This decrease in depreciation and
amortization was due to numerous assets becoming fully depreciated during 1997.
    
 
   
     General and Administrative Expenses
    
 
   
     General and administrative expenses increased to $293,600 for the year
ended December 31, 1997 from $270,143 for the year ended December 31, 1996, an
increase of $23,457, or 9%. This was due primarily to recruiting expense of
$27,117 incurred in 1997, but not in 1996.
    
 
   
     Interest Expense
    
 
   
     Interest expense totaled $1,762,404 for the year ended December 31, 1997,
compared to $1,824,452 for the year ended December 31, 1996, a decrease of
$62,048 or 3%. This decrease in interest expense was due to the forgiveness of
debt of $452,369 and the reduction of the interest rates charged on Your
Partnership's notes payable to related parties and notes payable to others from
13% to 9% per annum.
    
 
   
     Interest Income
    
 
   
     Interest income totaled $6,290 for the year ended December 31, 1997,
compared to $1,659 for the year ended December 31, 1996, an increase of $4,631,
or 279%. This increase is related to interest earned on operating funds.

Liquidity and Capital Resources
    
 
   
     Your Partnership has periodically required loans from the partners to cover
cash flow deficiencies; however, the partners are not obligated to provide
additional funds to cover further cash flow deficiencies. Accordingly, Your
Partnership's ability to continue operating in its present form is dependent
upon its ability to generate sufficient cash flow from operations to fund
necessary capital improvements, debt service and other cash flow needs that may
arise or to arrange for further loans from partners or other sources.
    
 
   
FIDUCIARY RESPONSIBILITY OF THE GENERAL PARTNER OF YOUR PARTNERSHIP
    
 
   
     Under applicable law, the general partner of Your Partnership is
accountable to Your Partnership as a fiduciary. Your Partnership Agreement
provides that neither the general partner of Your Partnership nor any of its
affiliates performing services on behalf of Your Partnership will be liable to
Your Partnership or any of the Offerees for any act or omission by any such
person if such person, in good faith, determined that such course of conduct was
in the best interests of Your Partnership, provided that such act or omission
did not constitute misconduct or negligence on the part of such person. As a
result, Offerees might have a more limited right of action in certain
circumstances than they would have in the absence of such a provision in Your
Partnership Agreement. The general partner of Your Partnership is owned by the
Company. See "Conflicts of Interest".
    
 
   
     Your Partnership Agreement also provides that the general partner of Your
Partnership and certain related parties are indemnified from losses, judgments,
liabilities, expenses and amounts paid in settlement of any claims sustained by
them in connection with Your Partnership (except to the extent indemnification
is prohibited by law) provided that the course of conduct did not constitute
negligence or misconduct on the part of the general partner or its affiliates.
Notwithstanding the foregoing, none of the above-mentioned persons is to be
indemnified by Your Partnership from liability, loss, damage, cost or expense
incurred by him in connection with any claim involving allegations that such
person violated federal or state securities laws unless (a) there has been a
successful adjudication on the merits of the claims of each count involving
alleged securities law violations as to the person seeking indemnification, (b)
such claims have been dismissed with prejudice on the merits by a court of
competent jurisdiction, or (c) a court of competent jurisdiction has approved a
settlement of the claims against the person seeking indemnification. In each of
the foregoing situations, the court of law considering the request for
indemnification must be advised as to the position of the Commission and any
other applicable regulatory authority regarding indemnification for violations
of securities laws. Indemnification may not be enforceable as to certain
liabilities arising from claims under the Securities Act and state securities
laws; and, in the opinion of the Commission, such indemnification is contrary to
the public policy and is therefore unenforceable.
    
 
   
     Your Partnership does not pay for any insurance, other than public
liability insurance, covering liability of the general partner of Your
Partnership or any other indemnified person for acts or omissions for which
indemnification is not permitted by Your Partnership Agreement. As part of its
assumption of liabilities in the consolidation, the Company will indemnify the
general partner of Your Partnership and their affiliates for periods prior to
and following the consolidation to the extent of the indemnity under the terms
of Your Partnership Agreement and applicable law.
    
 
   
DISTRIBUTIONS AND TRANSFERS OF UNITS
    
 
   
  Distributions
    
 
   
     The following table sets forth the distributions paid per Unit in the
periods indicated below. Amounts paid in the indicated quarter were determined
based upon operations of Your Partnership during the preceding quarter. The
original cost per Unit was $74,000. Your Partnership has not made any
distributions in the past and is not projecting to make any distributions in
1998.

  Transfers
    
 
   
     The Units are not listed on any national securities exchange or quoted on
the National Association of Securities Dealers Automated Quotations (the "NASDAQ
System"), and there is no established public trading market for the Units.
Secondary sales activity for the Units has been limited and sporadic. The
general partner of Your Partnership monitors transfers of the Units (a) because
the admission of the transferee as a substitute limited partner in Your
Partnership requires the consent of the general partner of Your Partnership
under Your Partnership Agreement, and (b) in order to track compliance with safe
harbor provisions to avoid treatment as a "publicly traded partnership" for tax
purposes. However, the general partner of Your Partnership does not monitor or
regularly receive or maintain information regarding the prices at which
secondary sale transactions in the Units have been effectuated. The general
partner of Your Partnership estimates, based solely on the transfer records of
Your Partnership (or Your Partnership's transfer agent), that the number of
Units transferred in sale transactions (i.e., excluding transactions believed to
be between related parties, family members or the same beneficial owner) was as
follows:

                         REPORT OF INDEPENDENT AUDITORS
    
 
   
To the Partners
    
   
Casa Del Mar Associates Limited Partnership
    
 
   
     We have audited the accompanying balance sheet of Casa Del Mar Associates
Limited Partnership, a limited partnership, as of December 31, 1997, and the
related statements of operations, partners' capital deficit and cash flows for
the year then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
    
 
   
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Casa Del Mar Associates
Limited Partnership at December 31, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.
    
 
   
     As discussed in Note 3 to the financial statements, the Partnership's
recurring deficiencies in cash flow raise substantial doubt about its ability to
continue as a going concern. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
    
   
                               DECEMBER 31, 1997
    
 
   
NOTE 1 -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     Casa Del Mar Associates Limited Partnership (the "Partnership") was formed
as a limited partnership under the laws of the state of Florida on August 26,
1988, to own and operate a senior living community consisting of a 154 unit
retirement center of individual apartments and a 60 unit personal care facility
for individuals requiring some additional assistance with the activities of
daily living. The community is known as Casa Del Mar located in Palm Beach
County, Florida.
    
 
   
     Allocations of cash distributions and net income and losses are made in
accordance with the Partnership Agreement.
    
 
   
     Real estate is recorded on the basis of cost and represents collateral for
the mortgage note payable. Depreciation is computed generally by the
straight-line method over the estimated useful lives of the related assets.
    
 
   
     Cash equivalents are defined as short-term, highly liquid investments with
original maturities of three months or less. The affiliated management company
maintains cash concentration accounts on behalf of affiliated entities which are
included in cash and cash equivalents.
    
 
   
     Deferred costs consist primarily of financing fees which are amortized over
the related term of the note.
    
 
   
     No provision has been made for income taxes or related credits, as the
results of operations are includable in the tax returns of the partners.
    
 
   
     Preparation of financial statements requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
    
 
   
     The accompanying unaudited financial statements of the Partnership as of
June 30, 1998 and for the six months ended June 30, 1998 and 1997 have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included and all such adjustments
are of a recurring nature.
    
 
   
     The financial statements should be read in conjunction with the audited
financial statements and notes thereto for the year ended December 31, 1997. It
should be understood that accounting measurements at interim dates inherently
involve greater reliance on estimates than at year-end. The results of
operations for the interim periods presented are not necessarily indicative of
the results for the entire year.
    
 
   
NOTE 2 -- PARTNERS' CAPITAL DEFICIT ADJUSTMENT
    
 
   
     Partners' capital deficit as of January 1, 1997 has been restated for the

NOTE 3 -- GOING CONCERN
    
 
   
     The partnership has incurred deficiencies in cash flow which have been
funded by notes from the partners; however, the partners are not obligated to
provide additional funds to cover future deficiencies in

cash flow. Continuation of the partnership operations in the present form is
dependent upon its ability to achieve cash flow, the partners providing
additional notes or obtaining other funds. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty.
    
 
   
NOTE 4 -- MORTGAGE NOTE PAYABLE
    
 
   
     The mortgage note payable is due in monthly installments of $112,016,
including interest at 8.12% through August 1, 2005. The monthly payment is based
on a 25 year amortization with a final payment due of $11,669,929. The mortgage
may be prepaid with the payment of a fee as outlined in the note agreement.
Maturities for the next five years are as follows:

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
    
 
   
To the Partners of
    
   
Casa Del Mar Associates Limited Partnership:
    
 
   
     We have audited the accompanying balance sheet of Casa Del Mar Associates
Limited Partnership (a Florida limited partnership, the "Partnership"), as of
December 31, 1996, and the related statements of operations, changes in
partners' deficit, and cash flows for the year then ended. These financial
statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
    
 
   
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
    
 
   
     As indicated in Note 8, the Partnership has experienced deficiencies in
cash flow and has required funding from its partners in the year ended December
31, 1997 and the six months ended June 30, 1998. Continuation of the
Partnership's operations in the present form is dependent on its ability to
achieve cash flow, additional funding from partners, or funding from other
sources.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Casa Del Mar Associates
Limited Partnership as of December 31, 1996, and the results of its operations
and its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                          NOTE TO FINANCIAL STATEMENTS
    
   
                            AS OF DECEMBER 31, 1996
    
 
   
1. THE PARTNERSHIP:
    
 
   
     Casa Del Mar Associates Limited Partnership (the "Partnership") was
organized as of August 26, 1988 pursuant to the laws of the state of Florida,
and according to the Agreement of Limited Partnership (the "Partnership
Agreement"), shall continue until December 31, 2038, unless sooner dissolved in
accordance with the Partnership Agreement.
    
 
   
     The Partnership operates a senior living community consisting of 214
apartment units in Palm Beach County, Florida (the "Facility"). The Facility
consists of two self-contained buildings. The first building is a 154-unit
retirement center consisting of a central amenity building and two wings of
individual apartments. The second building is a 60-unit personal care facility,
for those individuals requiring some additional assistance with the activities
of daily living.
    
 
   
     On July 12, 1996, a controlling interest in the Partnership's general
partner was acquired by NHP Real Estate Corporation, an affiliate of NHP
Incorporated (see Note 7).
    
 
   
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
    
 
   
USE OF ESTIMATES
    
 
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
    
 
   
CASH AND CASH EQUIVALENTS
    
 
   
     The Partnership considers all highly liquid investments with initial
maturities of 90 days or less to be cash equivalents.
    
 
   
     NHP Management Company ("NHPMC"), a wholly owned subsidiary of NHP
Incorporated, assumed property management responsibility for the Facility as
part of the purchase effective July 12, 1996. NHPMC maintains at banks
concentrated cash and cash equivalent accounts of affiliated entities for which
it provides property management services. As of December 31, 1996, NHPMC did not
hold any cash on behalf of the Partnership.
    
 
   
RENTAL REVENUE
    
 
   
     Property owned by the Partnership is subject to numerous tenant leasing
arrangement having initial terms of one year or less. Rental revenue from these
arrangements is recognized on a straight line basis over the appropriate lease
term.
    
 
   
DEPRECIATION
    
 
   
     Depreciation of the land improvements and building and improvements are
computed using the straight line method, assuming a 15 year and 27.5 year life,
respectively. Furniture, fixtures and equipment are depreciated using an
accelerated method, assuming an estimated useful life of 5 to 7 years.

                  NOTE TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
AMORTIZATION
    
 
   
     Deferred finance costs are amortized over the appropriate mortgage loan
period using the straight-line method, which approximates the effective interest
method. The related amortization is recorded within interest expense in the
accompanying statement of operations.
    
 
   
INCOME TAXES
    
 
   
     The Partnership is not a tax paying entity and, accordingly, no provision
has been recorded for Federal or state income tax purposes. The partners are
individually responsible for reporting their share of the Partnership's taxable
income on their income tax returns. In the event of an examination of the
Partnership's tax return by the Internal Revenue Service, the tax liability of
the partners could be changed if an adjustment in the Partnership's income is
ultimately sustained by the taxing authorities.
    
 
   
     Certain transactions of the Partnership may be subject to accounting
methods for income tax purposes that differ from the accounting methods used in
preparing these financial statements in accordance with generally accepted
accounting principles. Accordingly, the net income or loss of the Partnership
and the resulting balances in the partners' capital accounts reported for income
tax purposes may differ from the balances reported for those same items in these
financial statements.
    
 
   
IMPLEMENTATION OF NEW ACCOUNTING STANDARD
    
 
   
     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards ("SFAS") No. 121, "Accounting for the Impairment of
Long-Lived Assets and Assets to be Disposed Of," which the Partnership
implemented on January 1, 1996. The adoption of this statement did not have an
effect on the Partnership's financial position or results of operations.
    
 
   
3. PARTNERSHIP PROFITS AND LOSSES AND DISTRIBUTIONS:
    
 
   
     Net income of the Partnership is allocated to the partners, pro rata, based
on any negative capital account balances, until such negative capital balances
are eliminated; any remaining income is allocated to the partners, pro rata,
based on their respective percentage interests. Net losses are allocated to the
partners, pro rata, based on any positive capital balances, until such positive
capital balances are eliminated. Any remaining losses are allocated to the
partners, pro rata, based on their respective percentage interests. Net cash
flow is to be distributed, pro rata to the Preferred Limited Partners, until
each Preferred Limited Partner has received distributions equal to a cumulative,
simple 12% annual return on his net cash investment, as defined in the
Partnership Agreement. Any remaining net cash flow will be distributed in
accordance with the percentage interests.
    
 
   
4. MORTGAGE NOTES PAYABLE:
    
 
   
     The Partnership is indebted to Washington Capital DUS, Inc. for a first
mortgage note payable (the "First Mortgage Note") in the original amount of
$14,365,000 issued in September 1995. As of December 31, 1996, the First
Mortgage Note had an outstanding balance of $14,120,604. The First Mortgage note
is payable in monthly principal and interest payments of $112,016, with an
interest rate of 8.12% per annum until

</TABLE>
    
 
   
     In connection with the issuance of the First Mortgage Note, the Partnership
capitalized deferred finance costs of $338,980, which is shown net of
accumulated amortization of $33,898 as of December 31, 1996.
    
 
   
     The First Mortgage Note is secured by the buildings and improvements, as
well as other amounts deposited with the lender.
    
 
   
5. ADVANCES FROM AFFILIATE:
    
 
   
     Prior to July 12, 1996, the Partnership had been advanced funds from the
general partner. These advances bore interest at 9 percent per annum and were to
become due on December 31, 2002. In connection with the sale of the general
partner interest described in Note 1, any previously accrued and unpaid interest
was added to the principal balance, and the note was assigned to NHP
Incorporated. In addition, $102,112 in principal and accrued interest was
forgiven, resulting in a newly stated outstanding balance of $5,108,000. The
gain on forgiveness of debt is reflected as a capital contribution in the
accompanying statement of changes in partners' deficit. The new advance bears
interest at 9.75 percent per annum, with amounts payable monthly from net cash
flow, as defined in the note agreement. All unpaid principal and interest are
due and payable on July 12, 2006.

                  NOTE TO FINANCIAL STATEMENTS -- (CONTINUED)
    
 
   
6. NOTES PAYABLE:
    
 
   
     Prior to July 12, 1996, the Partnership was liable to Casa Del Mar
Participation Corporation, an affiliate of the Partnership, for a note payable
in the original amount of $2,000,000. This note bore interest at a rate of 13
percent, with variable monthly principal and interest payments, until September
1, 2002, when all unpaid amounts were to become due and payable. In connection
with the sale of the general partner interest described in Note 1, this note
payable was restructured such that any previously accrued and unpaid interest
was added to the principal balance and was assigned to Stephen A. Goldberg. In
addition, $350,257 in principal and accrued interest was forgiven, resulting in
newly stated principal balance of $1,428,000. This gain on forgiveness of debt
is reflected as an extraordinary item on the statement of operations. The new
note payable bears interest at 9.00 percent per annum, with amounts payable
monthly from net cash flow, as defined in the loan agreement. All unpaid
principal and interest are due and payable in July 2006.
    
 
   
     In addition, as of December 31, 1996, the Partnership was liable for two
notes payable, in the aggregate amount of $56,503, issued for the purpose of
acquiring business equipment. The loans accrued interest at 13.87 percent and
11.54 percent annually, with combined monthly payments of $2,668 and maturities
of October and November 1999, respectively.
    
 
   
7. RELATED-PARTY TRANSACTIONS:
    
 
   
     NHPMC is the project management agent under an agreement which extends,
subject to certain conditions, to the year 2020. Certain stockholders owning
approximately 60 percent of the voting stock of NHP Incorporated also control
the entity which holds the general partnership interest in the Partnership.
    
 
   
     During 1996, personnel working at the Facility were employees of NHP
Incorporated, and therefore the Facility reimbursed NHP Incorporated for the
actual salaries and related benefits, as reflected in the accompanying financial
statements. At December 31, 1996, trade payables include $196 due to NHP
Incorporated.
    
 
   
     During 1996, NHPMC received a fee of $106,187 for its services as
management agent for the period from July 12, 1996 through December 31, 1996. As
part of the management agreement, management fees are calculated as 6 percent of
the Facility's rental collections, with 4 percent paid currently, and the
remaining 2 percent deferred until January of the following year. As of December
31, 1996, $142,462 of deferred management fees is included in accrued management
fee on the accompanying balance sheet.
    
 
   
8. SUBSEQUENT EVENT:
    
 
   
     The Partnership has experienced deficiencies in cash flow and has required
funding from its partners in the year ended December 31, 1997 and the six months
ended June 30, 1998. Continuation of the Partnership's operations in the present
form is dependent on its ability to achieve cash flow, additional funding from
partners, or funding from other sources.

                    OPINION OF ROBERT A. STANGER & CO., INC.
 
                          PRELIMINARY FORM OF OPINION
 
AIMCO Properties, L.P.
1873 South Bellaire -- Suite 1700
Denver, Colorado 80222
 
Re:  Casa Del Mar Associates, L.P.
 
Gentlemen:
 
   
     You have advised us that AIMCO Properties, L.P. (the "Purchaser"), a
subsidiary of Apartment Investment and Management Company ("AIMCO"), which
directly or indirectly owns the general partner (the "General Partner") of Casa
Del Mar Associates Limited Partnership (the "Partnership") (the Purchaser,
AIMCO, the General Partner and other affiliates and subsidiaries of AIMCO are
referred to herein collectively as the "Company"), is contemplating a
transaction (the "Offer") in which a minority of the outstanding limited
partnership interests in the Partnership (the "Units") will be acquired by the
Purchaser in exchange for an offer price per Unit of $       in cash, or
Partnership Common Units of the Purchaser, or        Partnership Preferred Units
of the Purchaser, or a combination of any of such forms of consideration. The
limited partners of the Partnership (the "Limited Partners") will have the
choice to maintain their current interest in the Partnership or exchange their
Units for any or a combination of such forms of consideration. The amount of
cash offered per Unit is referred to herein as the "Offer Price."
    
 
     You have requested that Robert A. Stanger & Co., Inc. ("Stanger") provide
its opinion as to whether the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
     Since its founding in 1978, Stanger and its affiliates have provided
information, research, investment banking and consulting services to clients
located throughout the United States, including major New York Stock Exchange
member firms, insurance companies and over seventy companies engaged in the
management and operation of partnerships and real estate investment trusts. The
investment banking activities of Stanger include financial advisory and fairness
opinion services, asset and securities valuations, industry and company research
and analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.
 
     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
Stanger's valuation practice principally involves partnerships, partnership
securities and the assets typically held through partnerships, such as real
estate, oil and gas reserves, cable television systems and equipment leasing
assets.
 
     In the course of our analysis for rendering this opinion, we have, among
other things:
 
          1. Reviewed a draft of the Prospectus Supplement related to the Offer
     in a form management has represented to be substantially the same as will
     be distributed to the Limited Partners;
 
          2. Reviewed the Partnership's financial statements for the years ended
     December 31, 1995, 1996 and 1997, and for the period ending June 30, 1998,
     which the Partnership's management has indicated to be the most current
     available financial statements;
 
   
          3. Reviewed descriptive information concerning the property owned by
     the Partnership (the "Property"), including location, number of units and
     unit mix, age, amenities and land acreage;
    
 
          4.  Reviewed summary historical operating statements for the Property,
     for the years ended December 31, 1996 and 1997, and the six months ending
     June 30, 1998;
 
                                       B-1
<PAGE>   108
 
          5. Reviewed the 1998 operating budget for the Property prepared by the
     Partnership's management;
 
          6. [Reviewed multi-year operating projections for the Property and the
     Partnership prepared by the Partnership's management, including revenues
     and expenses, net operating income, occupancy, capital improvements, debt
     service, residual value, and, in the case of the Partnership, general and
     administrative expenses and cash distributions to the General Partners and
     the Limited Partners;]
 
          7. [Reviewed internal analysis prepared by the Partnership of the
     estimated current net liquidation value of the Partnership per Unit of
     limited partnership interest;]
 
          8. Discussed with management market conditions for the Property;
     conditions in the market for sales/acquisitions of properties similar to
     that owned by the Partnership; historical, current and expected operations
     and performance of the Property and the Partnership; the physical condition
     of the Property including any deferred maintenance; and other factors
     influencing value of the Property and the Partnership;
 
          9. Performed a site inspection of the Property;
 
          10. Reviewed data and discussed with local sources real estate rental
     market conditions in the market of the Property, and reviewed available
     information relating to acquisition criteria for income-producing
     properties similar to the Property;
 
          11. Reviewed information provided by the Company relating to debt
     encumbering the Property;
 
          12. [Reviewed any bids received for the Property or publicly disclosed
     tender offers for the Units during the past two years;] and
 
          13. Conducted such other studies, analyses, inquiries and
     investigations as we deemed appropriate.
 
     In rendering this opinion, we have relied upon and assumed, without
independent verification, the accuracy and completeness of all financial
information and management reports and data, and all other reports and
information contained in the Prospectus Supplement or that were provided, made
available or otherwise communicated to us by the Partnership and the Company. We
have not performed an independent appraisal, engineering study or environmental
study of the assets and liabilities of the Partnership. We have relied upon the
representations of the Partnership and the Company concerning, among other
things, any environmental liabilities, deferred maintenance and estimated
capital expenditures and replacement reserve requirements, the determination and
valuation of non-real estate assets and liabilities of the Partnership, the
terms and conditions of any debt encumbering the Property, the allocation of net
Partnership values between the General Partner, Special Limited Partner and
Limited Partners, and the transaction costs and fees associated with a sale of
the Property. We have also relied upon the assurance of the Partnership and the
Company that any financial statements, projections, capital expenditure
estimates, debt summaries, value estimates and other information contained in
the Prospectus Supplement or otherwise provided or communicated to us were
reasonably prepared and adjusted on bases consistent with actual historical
experience, are consistent with the terms of the Partnership Agreement, and
reflect the best currently available estimates and good faith judgments; that no
material changes have occurred in the value of the Property or other information
reviewed between the date such information was provided and date of this letter;
that the Partnership and the Company are not aware of any information or facts
that would cause the information supplied to us to be incomplete or misleading;
that the highest and best use of the Property is as improved; and that all
calculations were made in accordance with the terms of the Partnership
Agreement.
 
     In addition, you have advised us that upon consummation of the Offer, the
Partnership will continue its business and operations substantially as they are
currently being conducted and that the Partnership and the Company do not have
any present plans, proposals or intentions which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation
involving the Partnership; a sale of the Partnership's Property or the sale or
transfer of a material amount of the Partnership's other assets; any changes to
the Partnership's senior management or personnel or their compensation; any
changes in the
 
                                       B-2
<PAGE>   109
 
Partnership's present capitalization or distribution policy; or any other
material changes in the Partnership's structure or business.
 
     We have not been requested to, and therefore did not: (i) select the Offer
Price or the method of determining the Offer Price in connection with the Offer;
(ii) make any recommendation to the Partnership or its partners with respect to
whether to accept or reject the Offer or whether to accept the cash, Preferred
OP Units or Common OP Units if the Offer is accepted; (iii) solicit any third
party indications of interest in acquiring the assets of the Partnership or all
or any part of the Partnership; or (iv) express any opinion as to (a) the tax
consequences of the proposed Offer to the Limited Partners, (b) the terms of the
Partnership Agreement or of any agreements or contracts between the Partnership
and the Company, (c) the Company's business decision to effect the Offer or
alternatives to the Offer, (d) the amount of expenses relating to the Offer or
their allocation between the Company and the Partnership or tendering Limited
Partners; (e) the relative value of the cash, Preferred OP Units or Common OP
Units to be issued in connection with the Offer; and (f) any adjustments made to
determine the Offer price and the net amounts distributable to the Limited
Partners, including but not limited to, balance sheet adjustments to reflect the
Partnership's estimate of the value of current net working capital balances,
reserve accounts, and liabilities, and adjustments to the Offer Price for
distributions made by the Partnership subsequent to the date of the initial
Offer. We are not expressing any opinion as to the fairness of any terms of the
Offer other than the Offer Price for the Units.
 
     Our opinion is based on business, economic, real estate and capital market,
and other conditions as they existed and could be evaluated as of the date of
our analysis and addresses the Offer in the context of information available as
of the date of our analysis. Events occurring after that date could affect the
assumptions used in preparing the opinion.
 
     The summary of the opinion set forth in the Prospectus Supplement does not
purport to be a complete description of the analyses performed, or the matters
considered, in rendering our opinion. The analyses and the summary set forth
must be considered as a whole, and selecting portions of such summary or
analyses, without considering all factors and analyses, would create an
incomplete view of the processes underlying this opinion. In rendering this
opinion, judgment was applied to a variety of complex analyses and assumptions.
The assumptions made, and the judgments applied, in rendering the opinion are
not readily susceptible to partial analysis or summary description. The fact
that any specific analysis is referred to in the Prospectus Supplement is not
meant to indicate that such analysis was given greater weight than any other
analysis.
 
     Based upon and subject to the foregoing, it is our opinion that as of the
date of this letter the Offer Price is fair to the Limited Partners of the
Partnership from a financial point of view.
 
                                            Yours truly,
 
                                            Robert A. Stanger & Co., Inc.

PROSPECTUS
    
   
    
 
                  APARTMENT INVESTMENT AND MANAGEMENT COMPANY
   
                                $600,000,000 OF
    
   
                              PREFERRED STOCK AND
    
                              CLASS A COMMON STOCK
 
                             AIMCO PROPERTIES, L.P.
   
                  $200,000,000 OF PARTNERSHIP PREFERRED UNITS
    
   
                    $200,000,000 OF PARTNERSHIP COMMON UNITS
    
 
   
     We may offer and issue these securities in connection with acquisitions of
businesses, properties, securities or other assets. In addition, we may issue
our Class A Common Stock upon conversion of shares our Preferred Stock, and we
may also issue shares of our Preferred Stock and shares of our Class A Common
Stock in exchange for our Partnership Preferred Units or our Partnership Common
Units tendered for redemption.
    
 
   
     Apartment Investment and Management Company has elected to be taxed for
federal income tax purposes as a REIT. Our Class A Common Stock is listed on the
New York Stock Exchange under the symbol "AIV." On September 16, 1998, the last
reported sales price of our Class A Common Stock on the NYSE was $33 3/4 per
share. There is no public market for our Partnership Preferred Units or our
Partnership Common Units. However, after a one-year holding period, each of our
Partnership Common Units may be redeemed in exchange for a share of our Class A
Common Stock, or at our option, a cash amount equal to the market value of one
share of our Class A Common Stock at the time of the redemption (subject to
antidilution adjustments).
    
 
   
     SEE "RISK FACTORS" BEGINNING ON PAGE 5 FOR A DISCUSSION OF MATERIAL RISKS
IN CONNECTION WITH AN INVESTMENT IN THE SECURITIES, INCLUDING WITHOUT
LIMITATION, THE FOLLOWING RISKS:
    
 
   
     - Our acquisition and development activities expose us to several negative
       factors, including difficulty in managing our rapid growth, the
       incurrence of unforeseen costs, possible failure to realize projected
       occupancy and rental rates.
    
 
   
     - Our organizational documents do not limit the amount of debt that we may
       incur, and our Board of Directors may change our leverage policy at any
       time. Our cash flow from operations might be insufficient to make
       required debt payments, and we might be unable to refinance our debt at
       all or on terms as favorable as the terms of our existing debt. In
       addition, we are subject to debt covenants that may restrict our ability
       to make distributions to investors.
    
 
   
     - Our real estate investment and management activities expose us to several
       potentially negative factors that are beyond our control such as local
       economic conditions, intense competition, potential environmental
       liabilities and change of laws, any of which could negatively affect our
       financial condition or results of operations.
    
 
   
     - We and certain of our officers and/or directors and unconsolidated
       subsidiaries have entered into, and may in the future into certain
       transactions that may result in conflicts of interest between the us and
       such officers and/or directors and unconsolidated subsidiaries.
    
 
   
     - If Apartment Investment and Management Company fails to qualify as a
       REIT, it (i) would not be allowed a deduction for dividends it pays, (ii)
       would be subject to federal income tax at corporate rates, (iii) might
       need to borrow funds or liquidate investments on unfavorable terms in
       order to pay the applicable tax and (iv) would no longer be required to
       make distributions to stockholders.
    
 
   
     - Our charter limits the number of shares of our stock that may be held by
       any one investor. Consequently, our stockholders are limited in their
       ability to effect a change of our control.
    
 
   
     - Investors in our partnership units must hold their units for one year,
       subject to certain exceptions. Thereafter investors may transfer such
       partnership units, subject to the satisfaction of certain conditions,
       including the general partner's right of first refusal. Holders of our
       partnership units do not have the ability to vote for or remove the
       general partner, and therefor they can not effect a change of control of
       AIMCO Properties, L.P.
    
 
   
     To the extent not otherwise described herein, the form in which the
securities are to be issued, and the terms of such securities, including without
limitation, their specific designation, or aggregate initial offering price,

exchange terms, if any, voting or other rights, if any, and other specific terms
will be set forth in a Prospectus Supplement, together with the terms of
offering of such securities.
    
 
   
     NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES
COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED UPON THE
ADEQUACY OR ACCURACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
    
 
   
     THE ATTORNEY GENERAL OF THE STATE OF NEW YORK HAS NOT PASSED ON OR ENDORSED
THE MERITS OF THIS OFFERING. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

                                  THE COMPANY
 
     AIMCO, a Maryland corporation formed on January 10, 1994, is a
self-administered and self-managed REIT engaged in the ownership, acquisition,
development, expansion and management of multi-family apartment properties.
AIMCO is the second largest owner and manager of multifamily apartment
properties in the United States, based on apartment unit data compiled by the
National Multi Housing Council as of January 1, 1998.
 
   
     As of June 30, 1998, through its controlling interests in the AIMCO
Operating Partnership and other limited partnerships and limited liability
companies (collectively, the "Subsidiary Partnerships"), AIMCO owned or
controlled 58,345 units in 210 apartment properties (the "Owned Properties"),
held an equity interest in 74,318 units in 478 apartment properties (the "Equity
Properties"), and managed 68,248 units in 357 apartment properties for third
party owners and affiliates (the "Managed Properties" and, together with the
Owned Properties and Equity Properties, the "AIMCO Properties"), bringing the
total portfolio to 200,911 units in 1,045 apartment properties as of June 30,
1998. The AIMCO Properties are located in 42 states, the District of Columbia
and Puerto Rico.
    
 
   
     Substantially all of the operations of AIMCO are conducted through the
AIMCO Operating Partnership and its subsidiaries. As of June 30, 1998, AIMCO,
through its wholly owned subsidiaries, AIMCO-GP, Inc., the sole general partner
of the AIMCO Operating Partnership (the "AIMCO GP"), and AIMCO-LP (the "Special
Limited Partner"), a limited partner in the AIMCO Operating Partnership, held
approximately an 89% interest in the AIMCO Operating Partnership. AIMCO,
together with its consolidated subsidiaries, including the AIMCO Operating
Partnership, is herein sometimes referred to as the "Company."
    
 
     The principal executive offices of AIMCO and the AIMCO Operating
Partnership are located at 1873 South Bellaire Street, Denver, Colorado 80222,
and their telephone number is (303) 757-8101.
 
                              RECENT DEVELOPMENTS
 
AMBASSADOR MERGER
 
     On May 8, 1998, Ambassador Apartments, Inc. ("Ambassador") was merged into
AIMCO (the "Ambassador Merger"), and the outstanding shares of common stock, par
value $.01 per share, of Ambassador (the "Ambassador Common Stock"), were
converted into a total of 6,578,833 shares of Class A Common Stock. Upon the
consummation of the Ambassador Merger, Ambassador and its subsidiaries had
aggregate outstanding indebtedness of approximately $406.1 million, which by
operation of law became indebtedness of AIMCO or its subsidiaries upon
consummation of the Ambassador Merger. Ambassador was a self-managed REIT
engaged in the ownership and management of garden style apartment properties
leased primarily to middle income tenants. As of the consummation of the
Ambassador Merger, Ambassador owned 52 apartment communities with a total of
15,728 units located in Arizona, Colorado, Florida, Georgia, Illinois, Tennessee
and Texas. In addition, Ambassador managed one property containing 252 units for
an unrelated third party.
 
INSIGNIA MERGER
 
     AIMCO and the AIMCO Operating Partnership have entered into a merger
agreement (the "Insignia Merger Agreement") with Insignia Financial Group, Inc.
("Insignia") and Insignia/ESG Holdings, Inc. ("Holdings") pursuant to which
Insignia will be merged into AIMCO (the "Insignia Merger"). Insignia is a fully
integrated real estate services organization specializing in the ownership and
operation of securitized real estate assets. Insignia is the largest manager of
multifamily residential properties in the United States according to the 1998
National Multi Housing Counsel 50 Report published in March 1998. Insignia
performs property management, asset management, investor services, partnership
accounting, real estate investment banking, and real estate brokerage services
for various types of property owners, including approximately 900 limited
partnerships having approximately 350,000 limited partners. Insignia provides
property management services for approximately 192,000 multifamily units,
consisting of 115,000 units which are controlled by
 
                                        3
<PAGE>   116
 
   
Insignia and 77,000 units owned by third parties. The Insignia Merger was
approved by the AIMCO stockholders and the Insignia stockholders on September
14, 1998 and is subject to customary closing conditions. It is expected that the
Insignia Merger will be completed in October 1998.
    
 
   
     At the time of the Insignia Merger, Insignia will consist principally of:
(i) Insignia's interests in Insignia Properties Trust, a Maryland REIT, which is
a majority owned subsidiary of Insignia ("IPT"), and Insignia Properties, L.P.,
IPT's operating partnership ("IPLP"); (ii) 100% of the ownership of the Insignia
entities that provide multifamily property management and partnership
administrative services; (iii) Insignia's interest in multifamily coinvestments;
(iv) Insignia's ownership of subsidiaries that control multifamily properties
not included in IPT; (v) Insignia's limited partner interests in public and
private syndicated real estate limited partnerships; and (vi) assets incidental
to the foregoing businesses. The remaining businesses of Insignia were
transferred to Holdings and all of the capital stock of Holdings was distributed
to Insignia's stockholders (the "Distribution").
    
 
   
     The outstanding shares of Insignia's common stock will be converted into
the right to receive, in the aggregate, approximately $303 million of AIMCO's
Class E Preferred Stock (as defined below), (and, in certain cases, cash which
AIMCO, in its sole discretion, may elect to pay if the average trading price of
Class A Common Stock over a 20-day period ended five trading days prior to the
effective time of the Insignia Merger (the "Effective Time"), but in no event
greater than $38.00 (the "AIMCO Index Price") is less than $36.50). In addition
to receiving the same dividends as holders of shares of Class A Common Stock,
holders of Class E Preferred Stock will be entitled to receive a pro rata share
of a special dividend of $50 million in the aggregate (the "Special Dividend").
When the Special Dividend is paid in full, each share of Class E Preferred Stock
will automatically convert into one share of Class A Common Stock (subject to
certain antidilution adjustments). In addition, after the Insignia Merger,
approximately $458 million in outstanding debt and other liabilities of Insignia
and its subsidiaries will remain outstanding and become consolidated liabilities
of AIMCO and its affiliates.
    
 
   
     If the AIMCO Index Price is less than $36.50, then AIMCO may elect in its
sole discretion to pay part of the Merger Consideration received by Insignia
stockholders in cash by giving notice to Insignia that it has elected to do so,
which notice shall set forth the aggregate amount AIMCO has elected to pay in
cash (the "Aggregate Cash Amount"); provided, however, that the Aggregate Cash
Amount may not exceed the lesser of (i) $15,000,000 and (ii) the product of (x)
$36.50 less the AIMCO Index Price, multiplied by (y) the sum of the number of
shares of Insignia common stock outstanding at the Effective Time plus the
number of shares of Insignia common stock for which outstanding Insignia
Convertible Securities (see "Glossary") are exercisable, whether or not vested,
at the Effective Time.
    
 
   
     As of the date hereof, Insignia and its subsidiaries own approximately   %
of the outstanding shares of beneficial interest, par value $.01 per share, of
IPT ("IPT Shares"). The Insignia Merger Agreement requires AIMCO to propose to
acquire (by merger) all of the IPT Shares not owned by Insignia and its
subsidiaries, and to use its reasonable best efforts to consummate such merger
within three months following the Insignia Merger at a purchase price of not
less than $13.25 per IPT Share, payable in cash. Assuming a price of $13.25 per
IPT Share, the remaining   % of IPT, owned principally by private investors and
certain executives of Insignia, is valued at approximately $153.8 million.
    
 
   
     After consummation of the Insignia Merger, the AIMCO Operating Partnership
intends to offer to purchase limited partnership interests in syndicated real
estate limited partnerships in which AIMCO holds partnership interests. The
AIMCO Operating Partnership, subject to applicable law, plans to offer to
purchase certain of such limited partnership interests in exchange for (i)
equity securities of the AIMCO Operating Partnership to be issued pursuant to
the Registration Statement of which this Prospectus forms a part, (ii) cash or
(iii) a combination of such equity securities and cash. Such offers are expected
to include terms that will allow limited partners to continue to hold their
limited partnership interests.

                                  RISK FACTORS
 
   
     Before you invest in our securities, you should be aware that there are
various risks, including those described below. You should consider carefully
these risk factors together with all of the other information included in this
prospectus before you decide to purchase our securities.
    
 
   
     Some of the information in this prospectus may contain forward-looking
statements. Such statements can be identified by the use of forward-looking
terminology such as "may," "will," "expect," "anticipate," "estimate,"
"continue" or other similar words. These statements discuss future expectations,
contain projections of results of operations or of financial condition or state
other "forward-looking" information. When considering such forward-looking
statements, you should keep in mind the risk factors and other cautionary
statements in this prospectus. The risk factors noted in this section and other
factors noted throughout this prospectus, including certain risks and
uncertainties, could cause our actual results to differ materially from those
contained in any forward-looking statement.
    
 
   
RISKS OF ACQUISITION AND DEVELOPMENT ACTIVITIES
    
 
   
     Generally. The selective acquisition, development and expansion of
apartment properties is one component of our growth strategy. However, we can
make no assurance as to our ability to complete future acquisitions. Although we
seek acquisitions that are accretive on a per share basis, acquisitions may fail
to perform in accordance with our expectations. When we develop or expand
properties, we are subject to the risks that:
    
 
   
     - costs may exceed original estimates;
    
 
   
     - projected occupancy and rental rates at the property may not be realized;
    
 
   
     - financing may not be available on favorable terms;
    
 
   
     - construction and lease-up may not be completed on schedule;
    
 
   
     - we may experience difficulty or delays in obtaining necessary zoning,
       land-use, building, occupancy, and other governmental permits and
       authorizations.
    
 
   
     We May Have Difficulty Managing Our Rapid Growth. We have grown rapidly.
Since our initial public offering in July 1994, we have completed numerous
acquisition transactions, expanding our portfolio of AIMCO Properties from 132
properties with 29,296 units to 1,045 properties with 200,911 units. These
acquisitions have included purchases of properties, interests in entities that
own or manage properties and corporate mergers. The proposed Insignia Merger
will be our largest acquisition so far. Our ability to successfully integrate
acquired businesses and properties depends on our ability to:
    
 
   
     - attract and retain qualified personnel;
    
 
   
     - maintain uniform standards, controls, procedures and policies; and
    
 
   
     - maintain adequate accounting and information systems.
    
 
   
     We can provide no assurance that we will be able to accomplish these goals
and successfully integrate any acquired businesses or properties.
    
 
   
     We May Incur Additional Expenses if the Proposed Insignia Merger is
Terminated. We are obligated to pay Insignia $50 million in liquidated damages
if the Insignia Merger Agreement is terminated as a result of our breach of
certain representations, warranties or covenants, or our failure to satisfy
certain conditions to closing. Also, if the Insignia Merger Agreement is
terminated due to a breach by us, certain Insignia executives have the right to
require us to purchase certain of their shares of Insignia common stock. If all
such executives exercised this right, we would be required to purchase
approximately 6% of the shares of common stock of Insignia outstanding as of
July 31, 1998, at a cost of approximately $46.9 million.

     Litigation Associated with Partnership Acquisitions. We have engaged in,
and intend to continue to engage in, the selective acquisition of interests in
limited partnerships that own apartment properties. In some cases, we have
acquired the general partner of a partnership and then made an offer to acquire
the limited partners' interests in the partnership. In these transactions, we
are subject to litigation based on claims that the general partner has breached
its fiduciary duties to its limited partners or that the transaction violates
the relevant partnership agreement. Although we intend to comply with our
fiduciary obligations and relevant partnership agreements, we may incur defense
and settlement costs in connection with such litigation. In some cases, such
litigation may adversely affect our desire to proceed with, or our ability to
complete, a particular transaction.
    
 
   
RISKS ASSOCIATED WITH DEBT FINANCING
    
 
   
     Our strategy is generally to incur debt to increase the return on our
equity while maintaining acceptable interest coverage ratios. We seek to
maintain a ratio of free cash flow to combined interest expense and preferred
stock dividends of between 2:1 and 3:1. However, our Board of Directors could
change this strategy at any time and increase our leverage. Our organizational
documents do not limit the amount of debt that we may incur, and we have
significant amounts of debt outstanding. Payments of principal and interest may
leave us with insufficient cash resources to operate our properties or pay
distributions required to be paid in order to maintain our qualification as a
REIT. We are also subject to the risk that our cash flow from operations will be
insufficient to make required payments of principal and interest, and the risk
that existing indebtedness may not be refinanced or that the terms of any
refinancing will not be as favorable as the terms of existing indebtedness. If
we fail to make required payments of principal and interest on any debt, our
lenders could foreclose on the properties securing such debt with a consequent
loss of income and asset value to us. As of June 30, 1998, 94% of our Owned
Properties and 43% of our assets were encumbered by debt.
    
 
   
INCREASES IN INTEREST RATES MAY INCREASE OUR INTEREST EXPENSE
    
 
   
     As of June 30, 1998, approximately $182 million of our debt was subject to
variable interest rates. An increase in interest rates could increase our
interest expense and adversely affect our cash flow.
    
 
   
RISKS OF INTEREST RATE HEDGING ARRANGEMENTS
    
 
   
     From time to time, in anticipation of refinancing debt, we enter into
agreements to reduce the risks associated with increases in short term interest
rates. Although these agreements provide us with some protection against rising
interest rates, these agreements also reduce the benefits to us when interest
rates decline. These agreements involve the following risks:
    
 
   
     - interest rate movements during the term of the agreement may result in a
       gain or loss to us;
    
 
   
     - we may be exposed to losses if the hedge is not indexed to the same rate
       as the debt anticipated to be incurred; and
    
 
   
     - if the counterparty to the agreement fails to pay, we may incur a loss.
    
 
   
COVENANT RESTRICTIONS MAY LIMIT OUR ABILITY TO MAKE PAYMENTS TO OUR INVESTORS
    
 
   
     Some of our debt and other securities contain covenants that restrict our
ability to make distributions or other payments to our investors unless certain
financial tests or other criteria are satisfied. In some cases, our subsidiaries
are subject to similar provisions, which may restrict their ability to make
distributions to us. Our primary credit facility provides that we may make
distributions to our investors during any 12-month period in an aggregate amount
that does not exceed the greater of 80% of our funds from operations for such
period or such amount as may be necessary to maintain our REIT status. This
credit facility prohibits all distributions if certain financial ratios and
tests are not satisfied. If the Insignia Merger is completed, some of Insignia's
debt securities and the preferred stock that we will issue in the merger will
prohibit the payment of dividends on our capital stock if we fail to make the
payments required by those securities.
    
 
                                        6
<PAGE>   119
 
   
WE DEPEND ON DISTRIBUTIONS AND OTHER PAYMENTS FROM OUR SUBSIDIARIES
    
 
   
     All of our properties are owned, and all of our operations are conducted,
by the Operating Partnership and our other subsidiaries. As a result, we depend
on distributions and other payments from the Operating Partnership and other
subsidiaries in order to satisfy our financial obligations and make payments to
our investors. The ability of the AIMCO Operating Partnership and other
subsidiaries to make such distributions and other payments is dependent upon
their earnings and may be subject to statutory or contractual limitations. As an
equity investor in the AIMCO Operating Partnership and other subsidiaries, our
right to receive assets upon their liquidation or reorganization will be
effectively subordinated to the claims of their creditors. To the extent that we
are recognized as a creditor of the AIMCO Operating Partnership or such
subsidiaries, our claims would still be subordinate to any security interest in
or other lien on their assets and to any of their debt or other obligations that
are senior to us.
    
 
   
REAL ESTATE INVESTMENT RISKS
    
 
   
     Our ability to make payments to our investors depends on our ability to
generate funds from operations in excess of required debt payments and capital
expenditure requirements. Funds from operations and the value of our properties
may be adversely affected by events or conditions which are beyond our control.
Such events or conditions could include:
    
 
   
     - the general economic climate;
    
 
   
     - competition from other apartment communities and alternative housing;
    
 
   
     - local conditions, such as an increase in unemployment or an oversupply of
       apartments, that might adversely affect apartment occupancy or rental
       rates;
    
 
   
     - increases in operating costs (including real estate taxes) due to
       inflation and other factors, which may not necessarily be offset by
       increased rents;
    
 
   
     - changes in governmental regulations and the related costs of compliance;
    
 
   
     - changes in tax laws and housing laws, including the enactment of rent
       control laws or other laws regulating multifamily housing;
    
 
   
     - changes in interest rate levels and the availability of financing; and
    
 
   
     - the relative illiquidity of real estate investments.
    
 
POSSIBLE ENVIRONMENTAL LIABILITIES
 
   
     Various Federal, state and local laws subject property owners or operators
to liability for the costs of removal or remediation of certain hazardous
substances released on a property. Such laws often impose liability without
regard to whether the owner or operator knew of, or was responsible for, the
release of the hazardous substances. The presence of, or the failure to properly
remediate, hazardous substances may adversely affect occupancy at contaminated
apartment communities and our ability to sell or borrow against contaminated
properties. In addition to the costs associated with investigation and
remediation actions brought by governmental agencies, the presence of hazardous
wastes on a property could result in personal injury or similar claims by
private plaintiffs. Various laws also impose, on persons who arrange for the
disposal or treatment of hazardous or toxic substances, liability for the cost
of removal or remediation of hazardous substances at the disposal or treatment
facility. These laws often impose liability whether or not the person arranging
for the disposal ever owned or operated the disposal facility.
    
 
   
LAWS BENEFITTING DISABLED PERSONS MAY RESULT IN UNANTICIPATED EXPENSES
    
 
   
     Under the Americans with Disabilities Act of 1990 (the "ADA"), all places
of public accommodation are required to meet certain Federal requirements
related to access and use by disabled persons. These requirements became
effective in 1992. A number of additional Federal, state and local laws exist
which also may require modifications to our properties, or restrict certain
further renovations of the properties, with
    
 
                                        7
<PAGE>   120
 
   
respect to access thereto by disabled persons. For example, the Fair Housing
Amendments Act of 1988 (the "FHAA") requires apartment properties first occupied
after March 13, 1990 to be accessible to the handicapped. Noncompliance with the
ADA or the FHAA could result in the imposition of fines or an award of damages
to private litigants and also could result in an order to correct any
non-complying feature, which could result in substantial capital expenditures.
Although we believe that our properties are substantially in compliance with
present requirements, we may incur unanticipated expenses to comply with the ADA
and FHAA.
    
 
RISKS RELATING TO REGULATION OF AFFORDABLE HOUSING
 
   
     As of June 30, 1998, our portfolio included 375 Owned Properties, 96 Equity
Properties, and 81 Managed Properties that benefit from governmental programs
intended to provide housing to people with low or moderate incomes. These
programs, which are usually administered by the United States Department of
Housing and Urban Development ("HUD") or state housing finance agencies,
typically provide mortgage insurance, favorable financing terms, or rental
assistance payments to the property owners. As a condition to the receipt of
assistance under these programs, the properties must comply with various
requirements, which typically limit rents to pre-approved amounts. If permitted
rents on a property are insufficient to cover costs, a sale of the property may
become necessary, which could result in a loss of management fee revenue. We
usually need to obtain the approval of HUD in order to manage, or acquire a
significant interest in, a HUD-assisted or HUD-insured property. We can make no
assurance that we will always receive such approval.
    
 
   
THE LOSS OF PROPERTY MANAGEMENT CONTRACTS WOULD REDUCE OUR REVENUES
    
 
   
     We manage some properties owned by third parties. For the year ended
December 31, 1997, we and Insignia derived approximately 2% and 15%,
respectively, of our gross revenues from management of properties owned by third
parties. We may suffer a loss of revenue if we lose our right to manage these
properties or if the rental revenues upon which our management fees are based
declines. In general, management contracts may be terminated or otherwise lost
as a result of:
    
 
   
     - a disposition of the property by the owner in the ordinary course or as a
       result of financial distress of the property owner;
    
 
   
     - the property owner's determination that our management of the property is
       unsatisfactory;
    
 
   
     - willful misconduct, gross negligence or other conduct that constitutes
       grounds for termination; or
    
 
   
     - with respect to certain affordable properties, termination of such
       contracts by HUD or state housing finance agencies, generally at their
       discretion.
    
 
   
DEPENDENCE ON CERTAIN EXECUTIVE OFFICERS
    
 
   
     Although we have entered into employment agreements with each of Terry
Considine, Peter K. Kompaniez and Steven D. Ira, the loss of any of their
services could have an adverse effect on our operations.
    
 
   
POSSIBLE CONFLICTS OF INTEREST; TRANSACTIONS WITH AFFILIATES
    
 
   
     We have been, and continue to be, involved in various transactions with a
number of our affiliates, including executive officers, directors, and entities
in which they own interests. For example, in order to satisfy certain REIT
requirements, Messrs. Considine and Kompaniez directly or indirectly control the
companies that manage properties for third parties and affiliates. Although we
own a 95% non-voting interest in these management companies, we have no control
over them or their operations. As a result, the management companies could
implement business decisions or policies that are not in our best interests. We
have adopted certain policies designed to minimize or eliminate the conflicts of
interest inherent in these transactions, including a requirement that a majority
of our disinterested directors approve certain transactions with affiliates.
However, there can be no assurance that these policies will be successful in
eliminating the influence of such conflicts. Furthermore, such policies are
subject to change without the approval of our stockholders.

TAX RISKS
    
 
   
     Adverse Consequences of Failure to Qualify as a REIT. We believe that we
operate in a manner that enables us to meet the requirements for qualification
as a REIT for Federal income tax purposes. Although we do not plan to request a
ruling from the IRS that we qualify as a REIT, we have received an opinion from
the law firm of Skadden, Arps, Slate, Meagher & Flom LLP that we met the
requirements for qualification as a REIT for the taxable years ended December
31, 1994 through 1997, and that we are in a position to continue such
qualification.
    
 
   
     You should be aware that the opinion of our counsel is based upon certain
assumptions and representations and covenants made by us regarding the nature of
our business operations. Opinions of counsel are not binding on the IRS or any
court. Furthermore, our opinion of counsel is conditioned on, and our continued
qualification as a REIT will depend on, our ability to meet, through yearly
operating results, the various REIT qualification tests. Such requirements are
discussed in more detail under the heading "Federal Income Taxation of AIMCO and
AIMCO Stockholders -- General."
    
 
   
     If we fail to qualify as a REIT, we would not be allowed a deduction for
dividends to shareholders in computing our taxable income and we would be
subject to Federal income tax at regular corporate rates. In addition, unless we
are entitled to relief under the tax law, we could not elect to be taxed as a
REIT for four years following the year during which we were disqualified.
Therefore, if we lose our REIT status, the funds available for payment to our
investors would be reduced substantially for each of the years involved. See
"Federal Income Taxation of AIMCO and AIMCO Stockholders -- General -- Failure
to Qualify." Also, if we fail to qualify as a REIT, we would be obligated to
repurchase 750,000 shares of our preferred stock at a price of $105 per share,
plus accrued and unpaid dividends to the date of repurchase. See "Federal Income
Taxation of AIMCO and AIMCO Stockholders -- Failure to Qualify."
    
 
   
     For example, we will qualify as a REIT only if, as of the close of any year
in which we acquire a corporation that is a C Corporation (a corporation that
does not qualify for taxation as a REIT, such as Insignia), we have no "earnings
and profits" acquired from such C Corporation. In the Insignia Merger, we will
succeed to the earnings and profits of Insignia and, therefore, we must
distribute such earnings and profits effective on or before December 31, 1998.
Insignia has retained independent certified public accountants to determine
Insignia's earnings and profits through the effective time of the Insignia
Merger for purposes of this requirement. The determination of the independent
certified public accountants will be based upon Insignia's tax returns as filed
with the IRS and other assumptions and qualifications set forth in the reports
issued by such accountants. Any adjustments to Insignia's income for taxable
years ending on or before the closing of the Insignia Merger including as a
result of an examination of its returns by the IRS and the receipt of certain
indemnity or other payments could affect the calculation of Insignia's earnings
and profits. Furthermore, the determination of earnings and profits requires the
resolution of certain technical tax issues with respect to which there is no
authority directly on point and, consequently, the proper treatment of these
issues for earnings and profits purposes is not free from doubt. There can be no
assurance that the IRS will not examine the tax returns of Insignia and propose
adjustments to increase its taxable income and therefore its earnings and
profits. In this regard, the IRS can consider all taxable years of Insignia as
open for review for purposes of determining the amount of such earnings and
profits. Additionally, if the Special Dividend is not treated as a dividend
under the Code, AIMCO may, depending upon the amount of other distributions made
by AIMCO subsequent to the Insignia Merger (if consummated), fail to distribute
an amount equal to Insignia's earnings and profits. AIMCO's failure to
distribute an amount equal to such earnings and profits effective on or before
December 31, 1998, would result in AIMCO's failure to qualify as a REIT.
    
 
   
     Effect of Distribution Requirements. As a REIT, we are subject to annual
distribution requirements, which limit the amount of cash we have available for
other business purposes, including amounts to fund our growth. See "Federal
Income Taxation of AIMCO and AIMCO Stockholders -- Annual Distribution
Requirements."
    
 
   
     Possible Legislative or Other Actions Affecting REITs. The rules dealing
with Federal income taxation are constantly under review by persons involved in
the legislative process and by the IRS and the U.S. Treasury Department. Changes
to the tax law could adversely affect our investors. For example, a
    
                                        9
<PAGE>   122
 
   
proposal issued by President Clinton on February 2, 1998, if enacted into law,
may adversely affect our ability to expand the present activities of our
management subsidiaries. It cannot be predicted whether, when, in what forms, or
with what effective dates, the tax laws applicable to us or our investors will
be changed.
    
 
   
     Other Tax Liabilities. Even if we qualify as a REIT, we and our
subsidiaries may be subject to certain Federal, state and local taxes on our
income and property that could reduce operating cash flow.
    
 
   
POSSIBLE ADVERSE CONSEQUENCES OF LIMITS ON OWNERSHIP OF SHARES
    
 
   
     Our Charter limits ownership of our common stock by any single shareholder
to 8.7% of the outstanding shares (or 15% in the case of certain pension trusts,
registered investment companies and Mr. Considine). The Charter also prohibits
anyone from buying shares if the purchase would result in us losing our REIT
status. This could happen if a share transaction results in fewer than 100
persons owning all of our shares or in five or fewer persons, applying certain
broad attribution rules of the Internal Revenue Code, owning 50% or more of our
shares. If you or anyone else acquires shares in excess of the ownership limit
or in violation of the ownership requirements of the Internal Revenue Code for
REITs:
    
 
   
     - the transfer will be considered null and void;
    
 
   
     - we will not reflect the transaction on our books;
    
 
   
     - we may institute legal action to enjoin the transaction;
    
 
   
     - we may demand repayment of any dividends received by the affected person
       on those shares;
    
 
   
     - we may redeem the shares at their then current market price;
    
 
   
     - the affected person will not have any voting rights for those shares; and
    
 
   
     - the shares (and all voting and dividend rights of the shares) will be
       held in trust for the benefit of one or more charitable organizations
       designated by us.
    
 
   
     We may purchase the shares held in trust at a price equal to the lesser of
the price paid by the transferee of the shares or the then current market price.
If the trust transfers any of the shares, the affected person will receive the
lesser of the price he paid for the shares or the then current market price. An
individual who acquires shares that violate the above rules bears the risk that:
    
 
   
     - he may lose control over the power to dispose of the shares;
    
 
   
     - he may not recognize profit from the sale of such shares if the market
       price of the shares increases; and
    
 
   
     - he may be required to recognize a loss from the sale of such shares if
       the market price decreases.
    
 
   
OUR CHARTER AND MARYLAND LAW MAY LIMIT THE ABILITY OF A THIRD PARTY TO ACQUIRE
CONTROL OF THE COMPANY
    
 
   
     Ownership Limit. The 8.7% ownership limit discussed above may have the
effect of precluding acquisition of control of us by a third party without the
consent of our Board of Directors.
    
 
   
     Preferred Stock. Our Charter authorizes our Board of Directors to issue up
to 510,750,000 shares of capital stock. As of August 31, 1998, 496,027,500
shares were classified as Class A Common Stock, 262,500 shares were classified
as Class B Common Stock and 14,460,000 were classified as preferred stock. Under
the Charter, our Board of Directors has the authority to classify and reclassify
any of our unissued shares of capital stock into shares of preferred stock with
such preferences, rights, powers and restrictions as the Board of Directors may
determine. The authorization and issuance of preferred stock could have the
effect of delaying or preventing someone from taking control of us, even if a
change in control were in our shareholders' best interests.
    
 
   
     Maryland Business Statutes. As a Maryland corporation, we are subject to
various Maryland laws which may have the effect of discouraging offers to
acquire us and of increasing the difficulty of consummating any such offers,
even if our acquisition would be in our shareholders' best interests. The
Maryland General
    
 
                                       10
<PAGE>   123
 
   
Corporation Law restricts mergers and other business combination transactions
between us and any person who acquires beneficial ownership of shares of our
stock representing 10% or more of the voting power without our Board of
Directors' prior approval. Any such business combination transaction could not
be completed until five years after the person acquired such voting power, and
only with the approval of shareholders representing 80% of all votes entitled to
be cast and 66% of the votes entitled to be cast, excluding the interested
shareholder. Maryland law also provides that a person who acquires shares of our
stock that represent 20% or more of the voting power in electing directors will
have no voting rights unless approved by a vote of two-thirds of the shares
eligible to vote.
    
 
RISKS ASSOCIATED WITH AN INVESTMENT IN OP UNITS
 
   
     Restrictions on Transferability of OP Units. There is no public market for
our OP Units (see "Glossary"). In addition, our partnership agreement restricts
the transferability of OP Units. Until the expiration of a one year holding
period, subject to certain exceptions, investors may not transfer OP Units
without the consent of the general partner of the AIMCO Operating Partnership.
Thereafter investors may transfer such OP Units subject to the satisfaction of
certain conditions, including the general partner's right of first refusal. See
"Description of OP Units -- Transfers and Withdrawals." We have no plans to list
our OP Units on a securities exchange. It is unlikely that any person will make
a market in our OP Units, or that an active market for our OP Units will
develop. If a market for our OP Units develops and our OP Units are considered
"readily tradable" on a "secondary market (or the substantial equivalent
thereof)," the AIMCO Operating Partnership would be classified as a publicly
traded partnership for federal income tax purposes. See "-- Tax Treatment is
Dependent on Partnership Status; Publicly Traded Partnership Risks."
    
 
   
     Cash Distributions Are Not Guaranteed and May Fluctuate with Partnership
Performance. Although we make quarterly distributions on our OP Units, there can
be no assurance regarding the amounts of available cash that the AIMCO Operating
Partnership will generate or the portion that the general partner will choose to
distribute. The actual amounts of available cash will depend upon numerous
factors, including profitability of operations, required principal and interest
payments on our debt, the cost of acquisitions (including related debt service
payments), our issuance of debt and equity securities, fluctuations in working
capital, capital expenditures, adjustments in reserves, prevailing economic
conditions and financial, business and other factors, some of which may be
beyond the our control. Cash distributions are dependent primarily on cash flow,
including from reserves, and not on profitability, which is affected by non-cash
items. Therefore, cash distributions may be made during periods when the we
record losses and may not be made during periods when we record profits. We make
quarterly distributions to holders of Common OP Units (on a per unit basis) that
generally are equal to the dividends paid on the Class A Common Stock (on a per
share basis). However, such distributions will not necessarily continue to be
equal to such dividends.
    
 
   
     Our partnership agreement gives our general partner discretion in
establishing reserves for the proper conduct of the partnership's business that
will affect the amount of available cash. We are required to make reserves for
the future payment of principal and interest under our credit facilities and
other indebtedness. In addition, our credit facilities limit our ability to
distribute cash to holders of our OP Units. As a result of these and other
factors, there can be no assurance regarding our actual levels of cash
distributions on our OP Units, and our ability to distribute cash may be limited
during the existence of any events of default under any of our debt instruments.
    
 
   
     The AIMCO GP Manages and Operates the AIMCO Operating Partnership; OP
Unitholders Have Limited Voting Rights. The AIMCO GP manages and operates the
AIMCO Operating Partnership. Unlike the holders of common stock in a
corporation, OP Unitholders have only limited voting rights on matters affecting
the AIMCO Operating Partnership's business. OP Unitholders (see "Glossary") have
no right to elect the AIMCO GP on an annual or other continuing basis, and the
AIMCO GP may not be removed by OP Unitholders. As a result, OP Unitholders have
limited influence on matters affecting the operation of the AIMCO Operating
Partnership and third parties may find it difficult to attempt to gain control
or influence the activities of the AIMCO Operating Partnership.

<PAGE>   124
 
   
     The AIMCO Operating Partnership May Issue Additional Interests, Diluting OP
Unitholders' Interests. We may issue an unlimited number of additional OP Units
or other limited partner interests of the AIMCO Operating Partnership, for such
consideration and on such terms as may be established by the AIMCO GP in its
sole discretion, without your approval. The effect of any such issuance may be
to dilute the interests of OP Unitholders in distributions by the AIMCO
Operating Partnership.
    
 
   
     OP Unitholders May Not Have Limited Liability in Certain Circumstances. The
limitations on the liability of limited partners for the obligations of a
limited partnership have not been clearly established in some states. If it were
determined that the AIMCO Operating Partnership had been conducting business in
any state without compliance with the applicable limited partnership statute, or
that the right or the exercise of the right by the OP Unitholders as a group to
make certain amendments to the AIMCO Operating Partnership Agreement or to take
other action pursuant to the AIMCO Operating Partnership Agreement constituted
participation in the "control" of the AIMCO Operating Partnership's business,
then an OP Unitholder could be held liable under certain circumstances for the
AIMCO Operating Partnership's obligations to the same extent as the AIMCO GP.
    
 
     Conflicts of Interest and Fiduciary Responsibility. Conflicts of interest
have arisen and could arise in the future as a result of the relationships
between the AIMCO GP and its affiliates, on the one hand, and the AIMCO
Operating Partnership or any partner thereof, on the other. The directors and
officers of the AIMCO GP have fiduciary duties to manage the AIMCO GP in a
manner beneficial to AIMCO, as the sole stockholder of the AIMCO GP. At the same
time, the AIMCO GP, as general partner, has fiduciary duties to manage the AIMCO
Operating Partnership in a manner beneficial to the AIMCO Operating Partnership
and its partners. The duties of the AIMCO GP, as general partner, to the AIMCO
Operating Partnership and its partners, therefore, may come into conflict with
the duties of the directors and officers of the AIMCO GP to its sole
stockholder, AIMCO. Such conflicts of interest might arise in the following
situations, among others:
 
   
     - Decisions of the AIMCO GP with respect to the amount and timing of cash
       expenditures, borrowings, issuances of additional interests and reserves
       in any quarter will affect whether or the extent to which there is
       available cash to make distributions in a given quarter.
    
 
   
     - Under the terms of its partnership agreement, the AIMCO Operating
       Partnership will reimburse the AIMCO GP and its affiliates for costs
       incurred in managing and operating the AIMCO Operating Partnership,
       including compensation of officers and employees.
    
 
     - Whenever possible, the AIMCO GP seeks to limit the AIMCO Operating
       Partnership's liability under contractual arrangements to all or
       particular assets of the AIMCO Operating Partnership, with the other
       party thereto to have no recourse against the AIMCO GP or its assets.
 
   
     - Any agreements between the AIMCO Operating Partnership and the AIMCO GP
       and its affiliates will not grant to the OP Unitholders, separate and
       apart from the AIMCO Operating Partnership, the right to enforce the
       obligations of the AIMCO GP and such affiliates in favor of the AIMCO
       Operating Partnership. Therefore, the AIMCO GP, in its capacity as the
       general partner of the AIMCO Operating Partnership, will be primarily
       responsible for enforcing such obligations.
    
 
   
     - Under the terms of the AIMCO Operating Partnership Agreement, the AIMCO
       GP is not restricted from causing the AIMCO Operating Partnership to pay
       the AIMCO GP or its affiliates for any services rendered on terms that
       are fair and reasonable to the AIMCO Operating Partnership or entering
       into additional contractual arrangements with any of such entities on
       behalf of the AIMCO Operating Partnership. Neither the AIMCO Operating
       Partnership Agreement nor any of the other agreements, contracts and
       arrangements between the AIMCO Operating Partnership, on the one hand,
       and the AIMCO GP and its affiliates, on the other, are or will be the
       result of arms-length negotiations.
    
 
     Unless otherwise provided for in the relevant partnership agreement,
Delaware law generally requires a general partner of a Delaware limited
partnership to adhere to fiduciary duty standards under which it owes its
limited partners the highest duties of good faith, fairness and loyalty and
which generally prohibit such general partner from taking any action or engaging
in any transaction as to which it has a conflict of interest. The
 
                                       12
<PAGE>   125
 
   
AIMCO Operating Partnership Agreement expressly authorizes the AIMCO GP to enter
into, on behalf of the AIMCO Operating Partnership, a right of first opportunity
arrangement and other conflict avoidance agreements with various affiliates of
the AIMCO Operating Partnership and the AIMCO GP, on such terms as the AIMCO GP,
in its sole and absolute discretion, believes are advisable. The latitude given
in the AIMCO Operating Partnership Agreement to the AIMCO GP in resolving
conflicts of interest may significantly limit the ability of an OP Unitholder to
challenge what might otherwise be a breach of fiduciary duty. The AIMCO GP
believes, however, that such latitude is necessary and appropriate to enable it
to serve as the general partner of the AIMCO Operating Partnership without undue
risk of liability.
    
 
     The AIMCO Operating Partnership Agreement expressly limits the liability of
the AIMCO GP by providing that the AIMCO GP, and its officers and directors will
not be liable or accountable in damages to the AIMCO Operating Partnership, the
limited partners or assignees for errors in judgment or mistakes of fact or law
or of any act or omission if the AIMCO GP or such director or officer acted in
good faith. In addition, the AIMCO Operating Partnership is required to
indemnify the AIMCO GP, its affiliates and their respective officers, directors,
employees and agents to the fullest extent permitted by applicable law, against
any and all losses, claims, damages, liabilities, joint or several, expenses,
judgments, fines and other actions incurred by the AIMCO GP or such other
persons, provided that the AIMCO Operating Partnership will not indemnify for
(i) willful misconduct or a knowing violation of the law or (ii) for any
transaction for which such person received an improper personal benefit in
violation or breach of any provision of the AIMCO Operating Partnership
Agreement.
 
     The provisions of Delaware law that allow the common law fiduciary duties
of a general partner to be modified by a partnership agreement have not been
resolved in a court of law, and the AIMCO GP has not obtained an opinion of
counsel covering the provisions set forth in the AIMCO Operating Partnership
Agreement that purport to waive or restrict the fiduciary duties of the AIMCO GP
that would be in effect under common law were it not for the AIMCO Operating
Partnership Agreement.
 
   
     Certain Tax Risks Associated with an Investment in the OP Units. For a
general discussion of certain federal income tax consequences resulting from the
acquisition, holding, exchanging, and otherwise disposing of OP Units, see
"Federal Income Taxation of the AIMCO Operating Partnership and OP Unitholders."
    
 
   
     Tax Treatment is Dependent on Partnership Status; Publicly Traded
Partnership Risks. The availability to an OP Unitholder of the federal income
tax benefits of an investment in the AIMCO Operating Partnership depends on the
classification of the AIMCO Operating Partnership as a partnership for federal
income tax purposes. In the opinion of our legal counsel, which opinion is based
upon certain assumptions and representations by the AIMCO Operating Partnership
and on opinions of local counsel, with respect to matters of local law, the
AIMCO Operating Partnership will be classified as a partnership for federal
income tax purposes. The opinion is expressed as of its date and our counsel has
no obligation to advise OP Unitholders of any subsequent change in the matters
stated, represented or assumed or any subsequent change in the applicable law.
No advance ruling has been or will be sought from the IRS as to the
classification of the AIMCO Operating Partnership as a partnership. An opinion
of counsel is not binding on the IRS, and no assurance can be given that the IRS
will not challenge the status of the AIMCO Operating Partnership as a
partnership.
    
 
   
     If a market for the OP Units develops and the OP Units are considered
"readily tradable" on a "secondary market (or the substantial equivalent
thereof)," the AIMCO Operating Partnership would be classified as a publicly
traded partnership. We believe and intend to take the position that the AIMCO
Operating Partnership should not be classified as a publicly traded partnership
because (i) our OP Units are not traded on an established securities market and
(ii) our OP Units should not be considered readily tradable on a secondary
market or the substantial equivalent thereof. The determination of whether
interests in a partnership are readily tradable on a secondary market or the
substantial equivalent thereof, however, depends on various facts and
circumstances (including facts that are not within the control of the AIMCO
Operating Partnership). Although the Treasury regulations promulgated by the
U.S. Treasury Department under the Code (the "Treasury Regulations") and an IRS
pronouncement provide limited safe harbors, which, if satisfied, will prevent a
partnership's interests from being treated as readily tradable on a secondary
market or
    
 
                                       13
<PAGE>   126
 
the substantial equivalent thereof, the AIMCO Operating Partnership may not have
satisfied any of these safe harbors in its previous tax years. In addition,
because the AIMCO Operating Partnership's ability to satisfy a safe harbor may
involve facts that are not within its control, it is impossible to predict
whether the AIMCO Operating Partnership will satisfy a safe harbor in future tax
years. Such safe harbors are not intended to be substantive rules for the
determination of whether partnership interests are readily tradable on a
secondary market or the substantial equivalent thereof, and consequently, the
failure to meet these safe harbors will not necessarily cause the AIMCO
Operating Partnership to be treated as a publicly traded partnership. No
assurance can be given, however, that the IRS will not assert that partnerships
such as the AIMCO Operating Partnership constitute publicly traded partnerships,
or that facts and circumstances will not develop which could result in the AIMCO
Operating Partnership being treated as a publicly traded partnership.
 
   
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, it would nevertheless not be taxable as a corporation as long as
90% or more of its gross income consists of "qualifying income." In general,
qualifying income includes interest, dividends, real property rents (as defined
by section 856 of the Code) and gain from the sale or disposition of real
property. We believe that more than 90% of the gross income of the AIMCO
Operating Partnership consists of qualifying income and we expect that more than
90% of its gross income in future tax years will consist of qualifying income.
In such event, even if the AIMCO Operating Partnership were characterized as a
publicly traded partnership, it would not be taxable as a corporation. If the
AIMCO Operating Partnership were characterized as a publicly traded partnership,
however, each OP Unitholder would be subject to special rules under section 469
of the Code. See "Federal Income Taxation of the AIMCO Operating Partnership and
OP Unitholders -- Limitations on Deductibility of Losses; "Passive Activity
Loss" Limitation." No assurance can be given that the actual results of the
AIMCO Operating Partnership's operations for any one taxable year will enable it
to satisfy the qualifying income exception.
    
 
   
     If the AIMCO Operating Partnership were characterized as an association or
publicly traded partnership taxable as a corporation (because it did not meet
the qualifying income exception discussed above), it would be subject to tax at
the entity level as a regular corporation and OP Unitholders would be subject to
tax in the same manner as stockholders of a corporation. Thus, the AIMCO
Operating Partnership would be subject to federal tax (and possibly state and
local taxes) on its net income, determined without reduction for any
distributions made to the OP Unitholders, at regular federal corporate income
tax rates, thereby reducing the amount of any cash available for distribution to
the OP Unitholders, which reduction could also materially and adversely impact
the liquidity and value of the OP Units. In addition, the AIMCO Operating
Partnership's items of income, gain, loss, deduction and credit would not be
passed through to the OP Unitholders and the OP Unitholders would not be subject
to tax on the income earned by the AIMCO Operating Partnership. Distributions
received by an OP Unitholder from the AIMCO Operating Partnership, however,
would be treated as dividend income for federal income tax purposes, subject to
tax as ordinary income to the extent of current and accumulated earnings and
profits of the AIMCO Operating Partnership, and the excess, if any, as a
nontaxable return of capital to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest (without taking into account
Partnership liabilities), and thereafter as gain from the sale of a capital
asset. Characterization of the AIMCO Operating Partnership as an association or
publicly traded partnership taxable as a corporation would also result in the
termination of AIMCO's status as a REIT for federal income tax purposes which
would have a material adverse impact on AIMCO. See "Federal Income Taxation of
the AIMCO Operating Partnership and OP Unitholders -- Partnership Status." No
assurances can be given that the IRS would not challenge the status of the AIMCO
Operating Partnership as a "partnership" which is not "publicly traded" for
federal income tax purposes or that a court would not reach a result contrary to
such positions. Accordingly, each prospective investor is urged to consult his
tax advisor regarding the classification and treatment of the AIMCO Operating
Partnership as a "partnership" for federal income tax purposes.
    
 
     Consequences of Exchanging Property for OP Units. In general, no gain or
loss will be recognized for federal income tax purposes by a person contributing
property to the AIMCO Operating Partnership (the "Contributing Partner") in
exchange for OP Units, and the Contributing Partner will take a tax basis in the
OP Unit received equal to his adjusted tax basis in the contributed property.
Notwithstanding this general rule
 
                                       14
<PAGE>   127
 
   
of nonrecognition, a Contributing Partner may recognize a gain where the
property transferred is subject to liabilities, or the AIMCO Operating
Partnership assumes liabilities in connection with the transfer of property, and
the amount of such liabilities exceeds the amount of the AIMCO Operating
Partnership liabilities allocated to such person as determined immediately after
the transfer. Such excess is treated as a deemed distribution of cash to the
Contributing Partner from the AIMCO Operating Partnership which, in turn, is
treated as a nontaxable return of capital to the extent of the Contributing
Partner's adjusted tax basis in his OP Unit and thereafter as gain from the sale
of such partnership interest. If the Contributing Partner transfers property to
the AIMCO Operating Partnership and the adjusted tax basis of the property
differs from its fair market value, then AIMCO Operating Partnership Tax Items
must be allocated, for federal income tax purposes, in a manner such that the
Contributing Partner is charged with, or benefits from, respectively, the
unrealized gain or unrealized loss associated with the property of the time of
the contribution. See "Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Tax Consequences Upon Contribution of Property
to the AIMCO Operating Partnership."
    
 
   
     There are a variety of transactions that the AIMCO Operating Partnership
may in its sole discretion undertake following such contribution with respect to
the contributed property or the debt securing such property which could cause
the Contributing Partner to recognize taxable gain, even though little or no
cash is distributable to him as a result thereof. Such transactions include but
are not limited to (i) the sale of a particular property, which could result in
an allocation of gain only to those OP Unitholders who received OP Units with
respect to such property (even if cash attributable to sale proceeds were
distributed proportionately to all OP Unitholders); and (ii) a reduction in the
nonrecourse debt allocable to property (either because such debt becomes a
recourse liability or is paid off with cash flow, new equity, or proceeds of
debt secured by other property of the AIMCO Operating Partnership), which would
result in a deemed distribution of money to the OP Unitholders who received OP
Units with respect to such property as well as to the other OP Unitholders. See
"Federal Income Taxation of the AIMCO Operating Partnership and OP
Unitholders -- Tax Consequences Upon Contribution of Property to the AIMCO
Operating Partnership" and "Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Cash Distributions." The AIMCO Operating
Partnership Agreement grants the AIMCO GP broad authority to undertake such
transactions and does not grant the OP Unitholders affected by these actions any
rights to prevent the AIMCO GP from taking such actions. Even if the AIMCO GP
does not intend to sell or otherwise dispose of contributed property or to
reduce the debt, if any, securing such property within any specified time period
after the Contributing Partner transfers such property to the AIMCO Operating
Partnership, it is possible that future economic, market, legal, tax or other
considerations may cause the AIMCO Operating Partnership to dispose of the
contributed property or to reduce its debt. In this regard, the AIMCO Operating
Partnership Agreement provides that the AIMCO GP, while acting in its capacity
as general partner of the AIMCO Operating Partnership, may, but is not required
to, take into account the tax consequences to the OP Unitholders of its actions
in such capacity. The AIMCO GP intends to make decisions in its capacity as
general partner of the AIMCO Operating Partnership so as to maximize the
profitability of the AIMCO Operating Partnership as a whole, independent of the
tax effects on individual OP Unitholders.
    
 
   
     Tax Liability Exceeding Cash Distribution. An OP Unitholder will be
required to pay federal income tax and, in certain cases, state and local income
taxes, on his allocable share of the AIMCO Operating Partnership's income, even
if he receives no cash distributions from the AIMCO Operating Partnership. No
assurance can be given that an OP Unitholder will receive cash distributions
equal to his allocable share of taxable income from the AIMCO Operating
Partnership or even the tax liability to him resulting from that income.
Further, upon the sale of his OP Units, an OP Unitholder may incur a tax
liability in excess of the amount of cash received. See "Federal Income Taxation
of the AIMCO Operating Partnership and OP Unitholders -- Taxation of OP
Unitholders of AIMCO Operating Partnership," and "Federal Income Taxation of the
AIMCO Operating Partnership and OP Unitholders -- Sale, Redemption, or Exchange
of OP Units."
    
 
   
     Deductibility of Losses. An OP Unitholder's ability to use his allocable
share of losses, if any, from the AIMCO Operating Partnership at the end of the
taxable year in which the loss is incurred may be limited by
    
 
                                       15
<PAGE>   128
 
   
certain provisions of the Code. See "Federal Income Taxation of the AIMCO
Operating Partnership and OP Unitholders -- Limitations on Deductibility of
Losses."
    
 
   
     Potential Audits. The AIMCO Operating Partnership's tax return may be
audited, and any such audit could result in an audit of an OP Unitholder's tax
return as well as increased liabilities for taxes because of adjustments
resulting from the audit. No assurance can be given that the AIMCO Operating
Partnership will not be audited by the IRS or various state authorities or that
tax adjustments will not be made. Any adjustments in the AIMCO Operating
Partnership's tax return will lead to adjustments in an OP Unitholder's tax
return and may lead to audits of an OP Unitholder's tax return and adjustments
of items unrelated to the AIMCO Operating Partnership. Each OP Unitholder would
bear the cost of any expenses incurred in connection with an examination of such
OP Unitholder's tax return. See "Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Information Returns and Audit Procedures."
    
 
   
     State, Local and Other Tax Considerations. In addition to federal income
taxes, the AIMCO Operating Partnership and its OP Unitholders may be subject to
state, local and foreign taxation in various jurisdictions in which the AIMCO
Operating Partnership does business, owns property or resides. See "Other Tax
Consequences -- State, Local and Foreign Taxes."
    
 
   
     Tax Gain or Loss on Disposition of OP Units. An OP Unitholder who sells OP
Units will recognize gain or loss equal to the difference between the amount
realized (including his share of AIMCO Operating Partnership nonrecourse
liabilities) and his adjusted tax basis in such OP Units. Thus, prior AIMCO
Operating Partnership distributions in excess of cumulative net taxable income
in respect of an OP Unit which decreased an OP Unitholder's tax basis in such OP
Unit will, in effect, become taxable income if the OP Unit is sold at a price
greater than the OP Unitholder's tax basis in such OP Units, even if the price
is less than his original cost. A portion of the amount realized (whether or not

     The securities covered by this Prospectus (the "Securities") may be offered
and issued from time to time by AIMCO or the AIMCO Operating Partnership in
connection with acquisitions of businesses, properties, securities or other
assets. In addition, AIMCO may issue (i) shares of its Class A Common Stock, par
value $0.01 per share ("Class A Common Stock") covered hereby upon conversion of
shares its Preferred Stock, par value $0.01 per share ("Preferred Stock"), (ii)
shares of its Preferred Stock covered hereby and shares of its Class A Common
Stock covered hereby, in each case in exchange for Partnership Preferred Units
of the AIMCO Operating Partnership ("Preferred OP Units") tendered for
redemption pursuant to the AIMCO Operating Partnership Agreement and (iii)
shares of its Class A Common Stock covered hereby in exchange for Partnership
Common Units of the AIMCO Operating Partnership ("Common OP Units" and together
with the Preferred OP Units, the "OP Units") tendered for redemption pursuant to
the AIMCO Operating Partnership Agreement.
    
 
     It is expected that the terms of acquisitions involving the issuance of the
Securities will be determined by direct negotiations with owners or controlling
persons of the business, properties, securities or other assets to be acquired
or through exchange offers. It is expected that any shares of Class A Common
Stock or Common OP Units issued will be valued at prices based on or related to
market prices for the Class A Common Stock at or near the time the terms of such
acquisition are established or at or near the time such Securities are
delivered, or based on average market prices for periods ending at or near such
times. No underwriting discounts or commissions will be paid, although brokers'
or finders' fees may be paid from time to time with respect to specific
acquisitions, and AIMCO or the AIMCO Operating Partnership may issue the
Securities in full or partial payment of such fees. Any person receiving such
fees may be deemed to be an "underwriter," within the meaning of the Securities
Act.
 
     This Prospectus has also been prepared for use by the persons who may
receive from AIMCO or the AIMCO Operating Partnership Securities covered by the
Registration Statement in acquisitions and who may be entitled to offer such
Securities under circumstances requiring the use of a Prospectus (such persons
being referred to under this caption as "Securityholders"); provided, however,
that no Securityholder will be
 
                                       16
<PAGE>   129
 
authorized to use this Prospectus for any offer of such Security without first
obtaining the consent of AIMCO and the AIMCO Operating Partnership. AIMCO and
the AIMCO Operating Partnership may consent to the use of this Prospectus for a
limited period of time by the Securityholders and subject to limitations and
conditions which may be varied by agreement between AIMCO and the AIMCO
Operating Partnership and the Securityholders. Resales of such Securities may be
made on the NYSE or such other exchange on which the Securities may be listed,
in the over-the-counter market, in private transactions or pursuant to
underwriting agreements.
 
     Agreements with Securityholders permitting use of this Prospectus may
provide that any such offering be effected in an orderly manner through
securities dealers, acting as broker or dealer, selected by AIMCO and the AIMCO
Operating Partnership; that Securityholders enter into custody agreements with
one or more banks with respect to such shares; and that sales be made only by
one or more of the methods described in this Prospectus, as appropriately
supplemented or amended when required. The Securityholders may be deemed to be
underwriters within the meaning of the Securities Act.
 
     When resales are to be made through a broker or dealer selected by AIMCO
and the AIMCO Operating Partnership, it is anticipated that a member firm of the
NYSE may be engaged to act as the Securityholders' agent in the sale of shares
by such Securityholders. The member firm will be entitled to commissions
(including negotiated commissions to the extent permissible). Sales of shares by
the member firm may be made on the NYSE or other exchange from time to time at
prices related to prices then prevailing. Any such sales may be by block trade.
Any such member firm may be deemed to be an underwriter within the meaning of
the Securities Act and any commissions earned by such member firm may be deemed
to be underwriting discounts and commissions under such act.
 
     Upon AIMCO and the AIMCO Operating Partnership being notified by a
Securityholder that any block trade has taken place, a supplementary prospectus,
if required, will be filed pursuant to Rule 424 under the Securities Act,
disclosing the name of the member firm, the number of shares involved, the price
at which such shares were sold by such Securityholder, and the commissions to be
paid by such Securityholder to such member firm.
 
     This Prospectus may be supplemented or amended from time to time to reflect
its use for resales by persons who received Securities for whom AIMCO and the
AIMCO Operating Partnership have consented to the use of this Prospectus in
connection with resales of such Securities.
 
     In addition to the Securities offered hereby, AIMCO and the AIMCO Operating
Partnership may from time to time issue additional Securities through public
offerings or private placements. AIMCO and the AIMCO Operating Partnership may
make such future issuances of Securities in connection with its acquisition of
other businesses, properties, securities or other assets in business combination
transactions or for other purposes.

(1) On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
    shares of Class A Common Stock. On such date, AIMCO and Property Asset
    Management, L.L.C., and its affiliated companies and PDI Realty Enterprises,
    Inc. (collectively, the "Company Predecessors") engaged in a business
    combination and consummated a series of related transactions which enabled
    the Company to continue and to expand the property management and related
    businesses of the Company Predecessors.
 
   
(2) The ratio of earnings to fixed charges for the Company was computed by
    dividing earnings by fixed charges. For this purpose, "earnings" consists of
    income before minority interests (which includes equity in earnings of
    unconsolidated subsidiaries and partnerships only to the extent of dividends
    and distributions received) plus fixed charges (other than any interest
    which has been capitalized); and "fixed charges" consists of interest
    expense (including amortization of loan costs) and interest which has been
    capitalized. The ratio of earnings to fixed charges for the Company
    Predecessors was computed by dividing earnings by fixed charges. For this
    purpose, "earnings" consists of income (loss) before extraordinary items and
    income taxes plus fixed charges and "fixed charges" consists of interest
    expense (including amortization of loan costs).
    
 
(3) The earnings of the Company Predecessors for the period from January 1, 1994
    to July 28, 1994 were inadequate to cover fixed charges by $1,463,000.
 
   
(4) The ratio of earnings to combined fixed charges and preferred stock
    dividends for the Company was computed by dividing earnings by the total of
    fixed charges and preferred stock dividends. For this purpose, "earnings"
    consists of income before minority interests (which includes equity in
    earnings of unconsolidated subsidiaries and partnerships only to the extent
    of dividends and distributions received) plus fixed charges (other than any
    interest which has been capitalized); "fixed charges" consists of interest
    expense (including amortization of loan costs) and interest which has been
    capitalized; and "preferred stock dividends" consists of the amount of
    pre-tax earnings that would be required to cover preferred stock dividend
    requirements.
    
 
(5) The Company Predecessors did not have any shares of preferred stock
    outstanding during the period from January 1, 1993 through July 28, 1994.
 
   
(6) Pro forma reflects the Ambassador Merger, the Insignia Merger and all other
    significant completed transactions.

(a)  On July 29, 1994, AIMCO completed its initial public offering of 9,075,000
     shares of Class A Common Stock and issued 966,000 shares of convertible
     preferred stock and 513,514 unregistered shares of Class A Common Stock. On
     such date, the Company and the Company Predecessors engaged in a business
     combination and consummated a series of related transactions which enabled
     the Company to continue and expand the property management and related
     businesses of the Company Predecessors. The 966,000 shares of convertible
     preferred stock and 513,514 shares of Class A Common Stock were repurchased
     by AIMCO in 1995.
 
   
(b)  Represents the period January 1, 1994 through July 28, 1994, the date of
     the completion of the business combination with AIMCO.
    
 
(c)  In the second quarter of 1996, the Company reorganized the ownership of the
     service company, whereby the AIMCO Operating Partnership (i) owns all of
     the non-voting preferred stock of the service company, PAMS Inc.,
     representing a 95% economic interest, and (ii) owns the 1% general
     partnership interest in PAMS LP. PAMS Inc. owns the 99% limited partnership
     interest in PAMS LP. Substantially all the activity of PAMS Inc. is
     conducted by PAMS LP. Because the AIMCO Operating Partnership owns 95% of
     the economic value of PAMS Inc. and also controls the general partnership
     interest in PAMS LP, thereby controlling the activity of the partnership,
     the service company is consolidated. Prior to the reorganization, the
     Company reported the service company business on the equity method. The
     restatement has no impact on net income, but does increase third party and
     affiliate management and other income, management and other expenses,
     amortization of management company goodwill and depreciation of non-real
     estate assets. The Company has restated the balance sheet as of December
     31, 1995 and 1994, and the statements of income and statements of cash
     flows for the year ended December 31, 1995 and the period from January 10,
     1994 through December 31, 1994 to reflect the change.
 
(d)  Represents the Company's share of earnings from 83,431 units in which the
     Company purchased an equity interest from the NHP Real Estate Companies.
 
(e)  Represents the Company's equity earnings in the Unconsolidated
     Subsidiaries.
 
   
(f)  The Company's management believes that the presentation of funds from
     operations ("FFO"), when considered with the financial data determined in
     accordance with generally accepted accounting principles ("GAAP"), provides
     a useful measure of the Company's performance. However, FFO does not
     represent cash flow and is not necessarily indicative of cash flow or
     liquidity available to the Company, nor should it be considered as an
     alternative to net income as an indicator of operating performance. The
     Board of Governors of the National Association of Real Estate Investment
     Trusts ("NAREIT") defines FFO as net income (loss), computed in accordance
     with GAAP, excluding gains and losses from debt restructuring and sales of
     property, plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. AIMCO calculates FFO consistent with the
     NAREIT definition, adjusted for AIMCO's minority interest in the AIMCO
     Operating Partnership, plus amortization of management company goodwill,
     the non-cash deferred portion of the income tax provision for
     unconsolidated subsidiaries and less the payments of dividends on perpetual
     preferred stock. The Company's management believes that presentation of FFO
     provides investors with industry-accepted measurements which help
     facilitate an understanding of the Company's ability to make required
     dividend payments, capital expenditures and principal payments on its debt.
     There can be no assurance that AIMCO's basis of computing FFO is comparable
     with that of other REITs.

     Because AIMCO has elected to be taxed for federal income tax purposes as a
REIT, it is required to distribute annually to its stockholders at least 95% of
its "REIT taxable income," which, as defined by the Code and the Treasury
Regulations, is generally equivalent to net taxable ordinary income. AIMCO
measures its economic profitability and pays regular dividends to its
stockholders based on its operating results during the relevant period. The
future payment of dividends by AIMCO will be at the discretion of the AIMCO
Board (see "Glossary") and will depend on numerous factors, including financial
condition, capital requirements, the annual distribution requirements under the
provisions of the Code applicable to REITs and such other factors the AIMCO
Board deems relevant. See "Business of the Company -- Operating and Financial
Strategies; Dividend Policy."
    
 
     On January 22, 1998, the AIMCO Board voted to increase the annual dividend
rate on the Class A Common Stock to $2.25 per share. Such dividend increase was
effective commencing with the dividend with respect to the fourth quarter of
1997 paid on February 13, 1998 and is subject to the factors described above,
including AIMCO's future results of operations. The AIMCO Operating Partnership
makes quarterly distributions to holders of Common OP Units (on a per unit
basis) that generally are equal to the dividends paid on the Class A Common
Stock (on a per share basis). However, such distributions will not necessarily
continue to be equal to such dividends. See "Risk Factors -- Risks Associated
With an Investment in OP Units."

                            BUSINESS OF THE COMPANY
 
   
     The Company is the second largest owner and manager of multifamily
apartment properties in the United States, based on apartment unit data compiled
by the National Multi Housing Council as of January 1, 1998. As of June 30,
1998, the Company owned or managed 200,911 apartment units, owned or controlled
a total of 58,345 units in 210 apartment properties, had an equity interest in
non-consolidated partnerships that owned 74,318 units in 478 apartment
properties and managed 68,248 units in 357 apartment communities for third
parties and affiliates. In addition to the Managed Properties, the Company
manages all of the Owned Properties and a majority of the Equity Properties. The
AIMCO Properties are located in 42 states, the District of Columbia and Puerto
Rico. AIMCO has elected to be taxed as a REIT for federal income tax purposes.
AIMCO conducts substantially all of its operations through the AIMCO Operating
Partnership and its subsidiaries. As of June 30, 1998, AIMCO held approximately
an 89% interest in the AIMCO Operating Partnership. Certain terms used herein
are defined below in "-- Accounting Policies and Definitions."
    
 
OPERATING AND FINANCIAL STRATEGIES
 
     The Company uses the following operating and financing strategies to
attempt to meet its objective of providing long-term, predictable FFO per share:
 
     - Acquisition of Properties at Less Than Replacement Cost. The Company
       attempts to acquire properties at a significant discount to their
       replacement cost, which the Company believes will provide it with a
       competitive cost advantage in comparison to newly constructed properties.
 
     - Geographic Diversification. The Company operates in 42 states, the
       District of Columbia and Puerto Rico. This geographic diversification
       insulates the Company, to some degree, from inevitable downturns in any
       one market. Among Owned Properties and Equity Properties, Houston, Texas,
       the Company's largest single regional market, and Dallas, Texas, the
       Company's second largest regional market, accounted for approximately
       13.9% and 8.0%, respectively, of the properties in which the Company has
       an ownership interest, on a pro rata basis.
 
     - Market Growth. The Company seeks to operate in markets where population
       and employment growth are expected to exceed the national average and
       where it believes it can become a regionally significant owner or manager
       of properties. The average annual population and employment growth rates
       from 1990 to 1995 in The Company's five largest regional markets were
       2.3% and 2.6%, respectively, compared to national averages of 1.1% and
       1.7%, respectively. For the 1996 to 1999 period, average annual
       population and employment growth rates in The Company's five largest
       regional markets are forecasted to be 2.2% and 3.6%, respectively,
       compared with projected national averages of 0.9% and 2.0%, respectively.
 
     - Product Diversification. The Company's portfolio of apartment properties
       also span a range of apartment community types, both within and among
       markets. The Company's properties are located in both urban and suburban
       areas and range from garden apartments to high rises and from luxury
       townhomes to affordable properties.
 
   
     - Capital Replacement. The Company believes that the physical condition and
       amenities of its apartment communities are important factors in its
       ability to maintain and increase rental rates. The Company also believes
       that a program of regular maintenance of the quality of its apartments,
       rather than episodic renovation, contributes to the reliability of
       earnings per share. The Company presently allocates approximately $300
       annually per owned apartment unit for Capital Replacements and reserves
       unexpended amounts for future Capital Replacements. From time to time,
       the Company reevaluates its Capital Replacement requirements and updates
       the amount of its budgeted Capital Replacements per owned apartment unit
       accordingly. For the six months ended June 30, 1998, the Company charged
       approximately $6.6 million for Capital Replacements to its reserve, and
       spent approximately $13.5 million, and had aggregate cumulative
       unexpended Capital Replacement reserves of approximately $2.4 million at
       June 30, 1998.
    
 
                                       25
<PAGE>   138
 
   
     - Debt Financing. The Company's strategy is generally to incur debt to
       increase its return on equity while maintaining acceptable interest
       coverage ratios. The Company seeks to match debt maturities to the
       character of the assets financed. Accordingly, the Company uses
       predominantly long-term, fixed-rate and self-amortizing debt in order to
       avoid the refunding or repricing risks of short-term borrowings. The
       Company also uses short-term debt financing to fund acquisitions and
       generally expects to refinance such borrowings with proceeds from equity
       offerings or long-term debt financings. As of June 30, 1998,
       approximately 6% of the Company's outstanding debt was short-term debt
       and 94% was long-term debt.
    
 
     - Dispositions. From time to time, the Company sells properties that do not
       meet its return on investment criteria or that are located in areas where
       the Company does not believe that the long-term real estate values
       justify the continued investment in the properties. Three properties in
       Houston and one property in each of Dallas and Phoenix were sold in
       October 1997. The Company recognized a net gain of approximately $2.8
       million on the sales.
 
   
            In January 1998, the Company sold the Sun Valley Apartments, an
       apartment community containing 430 apartment units located in Salt Lake
       City, Utah, for $11.5 million, less selling costs of $0.3 million. The
       Company recognized a $3.3 million gain on the sale. Cash proceeds from
       the sale were used to repay a portion of the AIMCO Operating
       Partnership's outstanding short-term indebtedness.
    
 
   
            In September 1998, the Company sold the Rillito Village Apartments,
       an apartment community containing 272 apartments units located in Tuscon,
       Arizona, for $6.8 million. The Company recognized a gain on the sale of
       approximately $75,000 and used the cash proceeds to pay down a portion of
       the outstanding balance on the Credit Facilities and to pay closing
       costs.
    
 
     - Dividend Policy. The Company pays dividends and distributions to share
       its profitability with its stockholders and limited partners. For the
       years ended December 31, 1997, 1996 and 1995, AIMCO distributed 66.5%,
       72.3% and 75.1% of FFO to its stockholders. Amounts not distributed are
       available for reinvestment, stock repurchases, amortization of debt and
       provide a margin to insulate annual dividends from fluctuations in the
       Company's business. AIMCO's dividend for 1997 was $1.85 per share. It is
       the present policy of AIMCO to increase the dividend annually in an
       amount equal to one-half the rate of the projected increase in FFO,
       adjusted for capital replacements. In January 1998, AIMCO increased its
       dividend to $0.5625 per share per quarter, commencing with the February
       13, 1998 dividend payment which is equivalent to an annualized dividend
       of $2.25 per share of Class A Common Stock. The minimum annual
       distribution requirement for REITs, which require the distribution of
       approximately 95% of "REIT taxable income" (see "Federal Income Taxation
       of AIMCO and AIMCO Stockholders -- General"), may result in dividends
       increasing at a greater rate in the future.
 
GROWTH STRATEGIES
 
     The Company seeks growth through two primary sources -- acquisition and
internal expansion.
 
   
     Acquisition Strategies. The Company believes its acquisition strategies
will increase profitability and predictability of earnings by increasing its
geographic diversification, economies of scale and opportunities to provide
traditional ancillary services to tenants at the AIMCO Properties. Since AIMCO's
initial public offering in July 1994 (the "AIMCO IPO"), the Company has
completed 41 acquisition transactions involving a total of 120 properties for an
aggregate purchase price of approximately $1,132 million, including the
assumption and incurrence of $615 million of indebtedness, through July 31,
1998.
    
 
     The Company believes that its demonstrated ability to evaluate and complete
acquisitions, its property management record and its economies of scale, to the
extent that the Company can operate a property more efficiently than the
existing owner or some competing purchasers, all provide credibility and
advantage in negotiating acquisitions. In addition, the ability to issue OP
Units to sellers of properties may provide tax
 
                                       26
<PAGE>   139
 
deferral opportunities to sellers and could give the Company an advantage over
competing buyers that cannot offer such tax deferral opportunities. The Company
acquires additional properties primarily in three ways:
 
     - Direct Acquisitions. The Company may directly acquire individual
       properties or portfolios and controlling interests in entities that own
       or control such properties or portfolios. During the year ended December
       31, 1997, the Company has directly acquired 44 apartment properties for a
       total consideration of $467.4 million, consisting of $191.0 million in
       cash, approximately 1.9 million Common OP Units valued at $56.0 million
       and the assumption or incurrence of $220.4 million of indebtedness. See
       "-- Recent Property Acquisitions and Dispositions."
 
     - Acquisition of Managed Properties. The Company believes that its property
       management operations support its acquisition activities. Its
       relationships with owners of the Managed Properties may provide it with a
       means of learning of acquisition opportunities at an early stage of the
       sale process. In addition, its familiarity with the property and its
       ability to quickly evaluate the property give it an advantage in pursuing
       and completing any such acquisition in a timely fashion. Since the AIMCO
       IPO, the Company has acquired 12 properties comprising 3,530 units from
       its managed portfolio for $129.0 million.
 
   
     - Increasing its Interest in Partnerships. For properties where the Company
       owns a general partnership interest in the property-owning partnership,
       the Company may seek to acquire, subject to its fiduciary duties, the
       outstanding limited partnership interests for cash or, in some cases, in
       exchange for Common OP Units. After consummation of the Insignia Merger,
       the AIMCO Operating Partnership intends to offer to purchase limited
       partnership interests in syndicated real estate limited partnerships in
       which AIMCO holds partnership interests. The AIMCO Operating Partnership,
       subject to applicable law, plans to offer to purchase certain of such
       limited partnership interests in exchange for (i) equity securities of
       the AIMCO Operating Partnership to be issued pursuant to the Registration
       Statement of which this Prospectus forms a part, (ii) cash or (iii) a
       combination of such equity securities and cash. Such offers are expected
       to include terms that allow limited partners to continue to hold their
       limited partnership interests.
    
 
     - In November 1996, the Company acquired the English Partnerships, which
       owned 22 apartment properties. The Company subsequently purchased
       pursuant to tender offers to acquire all of the outstanding limited
       partnership interests of 25 of the English Partnerships, approximately
       46%, in the aggregate, of the outstanding limited partnership interests
       in such partnerships for $15.0 million in cash and approximately 71,500
       OP Units valued at $1.7 million.
 
     - As of December 31, 1997, the Company has also commenced tender offers to
       acquire all of the outstanding limited partnership interests in 26
       partnerships owning 25 properties for an aggregate amount of
       approximately $79.0 million. Through September 30, 1997, pursuant to such
       tender offers, the Company has purchased approximately 20.2%, in the
       aggregate, of the outstanding limited partnership interests for $16.0
       million in cash.
 
     Internal Growth Strategies. The Company pursues internal growth through the
following strategies:
 
     - Revenue Increases. The Company increases rents where feasible and seeks
       to improve occupancy rates. The Company believes that its policy of
       capital improvements, amenities and customer service allows it to
       maintain demand and to increase its rents above the rate of inflation in
       the local market. The Company's "same store" revenues from the Owned
       Properties (based on properties owned from period to period) have grown
       by 3.3% from the fiscal year ended December 31, 1995 to that ended
       December 31, 1996, and by 2.1% from the year ended December 31, 1996 to
       that ended December 31, 1997, compared to an urban consumer price
       inflation rate of 2.8% and 2.3% over the same periods.
 
     - Redevelopment of Properties. The Company believes redevelopment of
       selected properties in superior locations provides advantages over
       development of new properties, because, compared with new development,
       redevelopment generally can be accomplished with relatively lower
       financial risk, in less time and with reduced delays attributable to
       governmental regulation. Recently the Company acquired
 
                                       27
<PAGE>   140
 
       and redeveloped Sun Katcher, a 360-unit property in Jacksonville,
       Florida, at a cost of $8.9 million, including $4.9 million in
       redevelopment costs. The Company also recently commenced the renovation
       and upgrading of Bay West, a 376-unit property in Tampa, Florida, for a
       projected cost of $4.8 million, to reposition the property in the
       marketplace. In addition, the Company expects to undertake a major
       renovation of the Morton Towers apartments, a 1,277 unit property located
       in Miami Beach, Florida, at an estimated cost of $35 million. The Company
       generally finances redevelopment initially with borrowings from the
       Credit Facilities, and subsequently arranges permanent financing.
 
     - Expansion of Properties. The Company believes that expansion within or
       adjacent to existing AIMCO Properties also provides growth opportunities
       at lower risk than new development. Such expansion can offer cost
       advantages to the extent common area amenities and on-site management
       personnel can service the expanded property. Recently the Company
       constructed 92 additional units at Fairways, in Phoenix, Arizona, at a
       cost of $6.5 million. The Company is planning the construction of 42
       additional units at Township, in Littleton, Colorado, for a projected
       cost of more than $3.0 million. In addition, the Company owns or controls
       approximately 136 acres of vacant land, adjacent to existing Owned
       Properties or Equity Properties, which the Company believes is suitable
       for the development of approximately 1,300 apartment units. The Company
       generally finances expansions initially with borrowings from the Credit
       Facilities, and subsequently arranges permanent financing.
 
     - Conversion of Affordable Properties; Improvement of Performance. The
       Company believes that it may be able to significantly increase its return
       from its portfolio of affordable properties by improving operations at
       some of its properties or by converting some of its properties to
       conventional properties. While management of the Company has commenced
       review of the affordable properties, it has not yet made any
       determination as to the conversion of any affordable property.
 
   
     - Ancillary Services. The Company's management believes that its ownership
       and management of the AIMCO Properties provides it with unique access to
       a customer base for the sale of additional services which generate
       incremental revenues. The Company currently provides cable television,
       telephone services and carport, garage and storage space rental at
       certain AIMCO Properties. For example, as of June 30, 1998, the Company
       has installed cable television service to 12,600 units and currently has
       more than 7,400 subscribers.
    
 
     - Controlling Expenses. Cost reductions are accomplished by exploiting
       economies of scale. As a result of the size of its portfolio and its
       creation of regional concentrations of properties, the Company has the
       ability to leverage fixed costs for general and administrative
       expenditures and certain operating functions, such as insurance,
       information technology and training, over a larger property base. For
       example, the Company's insurance subsidiary provides workers'
       compensation and employer liability insurance company-wide, without
       incurring material incremental costs as the Company's property assets
       grow.
 
     The Company also instills cost discipline in its property managers by
benchmarking their operations against the local market and other AIMCO
Properties.

PROPERTY MANAGEMENT STRATEGIES
 
   
     Regional Hubs. The Company's property management strategy is to achieve
improvements in operating results by combining centralized financial control and
uniform operating procedures with localized property management decision making
and market knowledge. The Company's management operations are organized into 12
regional hubs, each supervised by a Regional Vice President, who have on average
17 years of experience in apartment management.

(1) Includes only units and apartment communities managed by the Company as of
    August 31, 1998. Does not include 15,188 units in 113 apartment communities
    in which the Company has an ownership interest but does not manage and 2,332
    senior living units, all of which are managed as a separate portfolio.
    
 
     Customer Service. The Company believes that resident satisfaction is
directly related to the experience and training of on-site management personnel.
The Company provides on-site management trained to respond promptly to
residents' needs. To improve customer service, the Company conducts annual
resident satisfaction surveys, guarantees that material defects will be
corrected in 24 hours and refunds related rent if that commitment is not met.
 
     Personnel Policies. The Company has attempted to reduce turnover and retain
experienced personnel by establishing an employee mentoring program and
providing managers with incentive-based compensation. In addition, managing
properties for third parties, the Company believes, improves performance at
Managed Properties and Owned Properties alike by subjecting property managers to
market-based pricing and service standards.
 
     START. Properties that are behind budget or face other significant
operating difficulties receive direct supervision and intervention from START, a
team of professionals, led by Executive Vice President Steven Ira, a founder of
the Company. Members of START focus on not more than 10 to 15 properties at any
one time, which allows them to focus sharply on the subject properties. START
also oversees due diligence on acquisitions and major construction activities.
 
     Management Incentives. The Company believes that equity ownership by
management and equity- and incentive-based compensation are important factors in
attracting, retaining and motivating the most qualified and experienced
personnel and directors. The Company's goal is to align management's interests
with those of stockholders through the use of equity-based compensation plans to
direct management's efforts towards enhancing shareholder value.

         amount of $45.5 million as of May 31, 1998.
 
   
     - On July 25, 1997, eleven senior managers of AIMCO purchased 1.1 million
       shares of Class A Common Stock at a price of $30 per share in exchange
       for promissory notes secured by such stock, which notes are recourse as
       to 25% of the principal owed.
    
 
   
     - AIMCO pays a majority of the compensation to its outside directors in
       Class A Common Stock.
    
 
   
     - AIMCO issues all Stock options at the then-current market price, and
       requires that employees own Class A Common Stock before receiving their
       options. As of May 31, 1998, the number of outstanding options was
       5,235,997.
    
 
     On January 21, 1998, the AIMCO Operating Partnership sold an aggregate of
15,000 OP Units designated as Class I High Performance Units (the "High
Performance Units") to a joint venture formed by fourteen of the Company's
officers, and to three of AIMCO's non-employee directors for an aggregate
purchase price of $2,070,000, of which $1,980,300 was paid by the joint venture
and an aggregate of $89,700 was paid by three non-employee directors. The
purchase price of the High Performance Units was determined by the AIMCO Board,
based upon the advice of an independent valuation expert that this purchase
price represented the fair market value of the High Performance Units. The sale
of the High Performance Units was ratified by the stockholders on May 8, 1998.
 
     Holders of High Performance Units have no rights to receive distributions
or allocations of income or loss, or to redeem their High Performance Units
prior to the date (the "Valuation Date") that is the earlier of (i) January 1,
2001, or (ii) the date on which a change of control occurs. If, on the Valuation
Date, the cumulative Total Return of the Class A Common Stock from January 1,
1998 to the Valuation Date (the "Measurement Period") exceeds 115% of the
cumulative Total Return (as defined below) of a peer group index over the same
period, and is at least the equivalent of a 30% cumulative Total Return over
three years (the "Minimum Return"), then, on and after the Valuation Date,
holders of the 15,000 High Performance Units will be entitled to receive
distributions and allocations of income and loss from the AIMCO Operating
Partnership in the same amounts and at the same times (subject to certain
exceptions upon liquidation of the AIMCO Operating Partnership) as would holders
of a number of OP Units equal to the quotient obtained by dividing (i) the
product of (A) 15% of the amount by which the cumulative Total Return of the
Class A Common Stock over the Measurement Period exceeds the greater of 115% of
the peer group index or the Minimum Return, multiplied by (B) the weighted
average market value of the Company's equity capitalization (including Class A
Common Stock and OP Units) by (ii) the market value of one share of Class A
Common Stock on the Valuation Date. If, on the Valuation Date, the cumulative
Total Return of the Class A Common Stock does not satisfy these criteria, then,
on and after the Valuation Date, holders of the 15,000 High Performance Units
will be entitled to receive distributions and allocations of income and loss
from the AIMCO Operating Partnership in the same amounts and at the same times
(subject to certain exceptions upon a liquidation of the AIMCO Operating
Partnership) as would holders of 150 OP Units. For purposes of
 
                                       30
<PAGE>   143
 
determining the market value of Class A Common Stock or OP Units as of any date,
the average closing price of the Class A Common Stock for the 20 trading days
immediately preceding such date is used. It is expected that the Morgan Stanley
REIT Index, a capitalization-weighted index with dividends reinvested of the
most actively traded real estate investment trusts, will be used as the peer
group index for purposes of the High Performance Units.
 
     "Total Return" means, for any security and for any period, the cumulative
total return for such security over such period, as measured by (i) the sum of
(a) the cumulative amount of dividends paid in respect of such security for such
period (assuming that all cash dividends are reinvested in such security as of
the payment date for such dividend based on the security price on the dividend
payment date), and (b) an amount equal to (x) the security price at the end of
such period, minus (y) the security price at the beginning of such period,
divided by (ii) the security price at the beginning of the measurement period;
provided, however, that if the foregoing calculation results in a negative
number, the "Total Return" shall be equal to zero.
 
     Upon the occurrence of a change of control, any holder of High Performance
Units may, subject to certain restrictions, require the AIMCO Operating
Partnership to redeem all or a portion of the High Performance Units held by
such party in exchange for a cash payment per unit equal to the market value of
a share of Class A Common Stock at the time of redemption. However, in the event
that any High Performance Units are tendered for redemption, the AIMCO Operating
Partnership's obligation to pay the redemption price is subject to the prior
right of AIMCO to acquire such High Performance Units in exchange for an equal
number of shares of Class A Common Stock (subject to certain adjustments).
 
ACCOUNTING POLICIES AND DEFINITIONS
 
     The Company has the following accounting policies and definitions:
 
   
          The Board of Governors of NAREIT defines FFO as net income (loss),
     computed in accordance with generally accepted accounting principles,
     excluding gains and losses from debt restructuring and sales of property,
     plus real estate related depreciation and amortization (excluding
     amortization of financing costs), and after adjustments for unconsolidated
     partnerships and joint ventures. The Company calculates FFO in a manner
     consistent with the NAREIT definition, which includes adjustments for
     minority interest in the AIMCO Operating Partnership, plus amortization of
     management company goodwill, the non-cash deferred portion of the income
     tax provision for unconsolidated subsidiaries and less the payment of
     dividends on perpetual preferred stock. The Company's management believes
     that presentation of FFO provides investors with industry accepted
     measurements which help facilitate understanding of the Company's ability
     to meet required dividend payments, capital expenditures, and principal
     payments on its debt. There can be no assurance that the Company's basis of
     computing FFO is comparable with that of other REITs.
    
 
          The Company capitalizes spending for items which generally cost more
     than $250 and have a useful life of more than one year, such as carpet
     replacement, new appliances, new roofs or parking lot repaving. Capitalized
     spending which maintains a property is termed a "Capital Replacement." In
     the experience of the Company's management, this spending is better
     considered a recurring cost of preserving an asset rather than an
     additional investment.
 
          For financial reporting purposes, the Company consolidates entities in
     which it owns both a general partnership interest and controls investment
     decisions with respect to the underlying assets. The Company generally has
     a 30% to 51% economic interest in such entities. Entities in which the
     Company has less than a 30% economic interest or limited control are
     accounted for on the equity method.
 
          The Company policy is generally to hold Class C properties and
     affordable properties (substantially all of which are Class C properties)
     in unconsolidated partnerships. The Company accounts for these properties
     on the equity method in accordance with GAAP.

POLICIES OF THE COMPANY WITH RESPECT TO CERTAIN OTHER ACTIVITIES
 
     The following is a discussion of certain other investment objectives and
policies, financing policies and other policies of the Company. These policies
are determined by the officers and directors of AIMCO and may be amended or
revised from time to time at their discretion without a vote of AIMCO's
stockholders. As the sole general partner of the AIMCO Operating Partnership,
AIMCO also determines the investment policies of the AIMCO Operating
Partnership.
 
     Investment in Others. The Company may also participate with other entities
in property ownership, through joint ventures or other types of co-ownership.
Any such equity investment may be subject to existing mortgage financing and
other indebtedness which would have priority over the equity of the Company in
that property.
 
     Securities of or Interests in Persons Primarily Engaged in Real Estate
Activities. The Company may also acquire securities of or interests in persons
engaged in the acquisition, redevelopment and/or management of multifamily
apartment properties.
 
     Investments in Real Estate Mortgages. While the Company generally
emphasizes direct real estate investments, it may, in its discretion and subject
to the percentage ownership limitations and gross income tests necessary for
REIT qualification, invest in mortgage and other indirect real estate interests,
including securities of other real estate investment trusts. The Company has not
previously invested in mortgages or securities of other real estate investment
trusts and the Company does not presently intend to invest to a significant
extent in mortgages or securities of other real estate investment trusts.
 
     Operating and Financing Policies. The Company seeks to maintain a ratio of
EBITDA (less a provision of approximately $300 per owned apartment unit) to debt
(the "Debt Coverage Ratio") of at least 2 to 1, and to match debt maturities to
the character of the assets financed. See "-- Operating and Financial
Strategies -- Debt Financing." The Company, however, may from time to time
re-evaluate borrowing policies in light of then current economic conditions,
relative costs of debt and equity capital, market values of properties, growth
and acquisition opportunities and other factors. The Company may modify its
borrowing policy and may increase or decrease its Debt Coverage Ratio policy.
 
     To the extent that the AIMCO Board determines to seek additional capital,
the Company may raise such capital through additional equity offerings, debt
financing or retention of cash flow (after consideration of provisions of the
Code requiring the distribution by a REIT of a certain percentage of taxable
income and taking into account taxes that would be imposed on undistributed
taxable income), or through a combination of these sources. The Company
presently anticipates that any additional borrowings will be made through the
AIMCO Operating Partnership, although AIMCO might incur borrowings that would be
reloaned to the AIMCO Operating Partnership. The AIMCO Operating Partnership
cannot incur indebtedness that is recourse to AIMCO without AIMCO's approval.
AIMCO may approve the AIMCO Operating Partnership's incurring additional debt
that is recourse to the AIMCO Operating Partnership. Borrowings may be unsecured
or may be secured by any or all assets of AIMCO, the AIMCO Operating
Partnership, or any existing or new property and may have full or limited
recourse to all or any portion of the assets of AIMCO, the AIMCO Operating
Partnership, or any existing or new property.
 
     The Company has not established any limit on the number or amount of
mortgages that may be placed on any single property or on its portfolio as a
whole.
 
   
     AIMCO may also determine to issue securities senior to the Class A Common
Stock, including preferred stock and debt securities (either of which may be
convertible into capital stock or be accompanied by warrants to purchase capital
stock). The Company may also determine to finance acquisitions through the
exchange of properties or issuance of additional OP Units, shares of Class A
Common Stock or other securities.
    
 
     If the AIMCO Board determines to raise additional equity capital, the AIMCO
Board has the authority, without stockholder approval, to issue additional
shares of Class A Common Stock or other capital stock (including securities
senior to the Class A Common Stock) in any manner (and on such terms and for
such consideration) it deems appropriate, including in exchange for property.
Such issuances might cause a dilution
 
                                       32
<PAGE>   145
 
of a stockholder's investment in AIMCO. If the AIMCO Board determines to raise
additional equity capital to fund investments by the AIMCO Operating
Partnership, AIMCO will contribute such funds to the AIMCO Operating Partnership
as a contribution to capital and purchase of additional general partnership
interests. AIMCO may issue additional shares of Class A Common Stock in
connection with the acquisition of OP Units that are tendered to the AIMCO
Operating Partnership for redemption.
 
     The AIMCO Board also has the authority to cause the AIMCO Operating
Partnership to issue additional OP Units in any manner (and on such terms and
for such consideration) as it deems appropriate, including in exchange for
property. Any such new OP Units will be redeemable at the option of the holder,
which redemption AIMCO intends to cause to be made in Class A Common Stock
pursuant to the redemption rights.
 
     Conflict of Interest Policies. The Company has adopted certain policies
designed to minimize or eliminate conflicts of interests between the Company and
its executive officers and directors. Without the approval of a majority of the
disinterested directors, the Company will not (i) acquire from or sell to any
director, officer or employee of the Company or any entity in which a director,
officer or employee of the Company owns more than a 1% interest, or acquire from
or sell to any affiliate of any of the foregoing, any assets or other property
of the Company, (ii) make any loan to or borrow from any of the foregoing
persons, or (iii) engage in any material transaction with the foregoing. In
addition, the Company has entered in to employment agreements with Messrs.
Considine, Kompaniez and Ira which include provisions intended to eliminate or
minimize potential conflicts of interest, and which provide that those persons
will be prohibited from engaging directly or indirectly in the acquisition,
development, operation or management of other multifamily apartment properties
outside of the Company, except with respect to certain investments currently
held by such persons, as to which investments those persons have committed to an
orderly liquidation. There can be no assurance, however, that these policies
always will be successful in eliminating the influence of such conflicts, and if
they are not successful, decisions could be made that might fail to reflect
fully the interests of AIMCO's stockholders as a whole.
 
   
     Policies with Respect to Other Activities. The Company has authority to
offer shares of its capital stock or other securities and to repurchase or
otherwise reacquire its shares or any other securities, has done so, and may
engage in such activities in the future. From its inception, the Company has
made loans aggregating $5.1 million to certain entities owning properties
subsequently acquired by the Company. No balances remain outstanding on such
loans. In the same period, the Company has made loans aggregating $76.5 million
to its officers for the purchase of Class A Common Stock and $5.1 million to its
officers and other entities to acquire interests in subsidiaries of the Company.
The outstanding balances on such loans as of August 31, 1998 were $42.7 million
and $3.1 million, respectively. Messrs. Considine and Kompaniez have repaid in
part, using $2.0 million in proceeds distributed to them from the sale of NHP
Common Stock by AIMCO/NHP Holdings, Inc. ("ANHI") to AIMCO, outstanding
promissory notes payable by them to ANHI in an aggregate amount of $3.2 million,
which loan was made to them by ANHI to acquire their interest in ANHI. In
addition, the Company from time to time advances amounts for relocation and
other expenses. The Company has not engaged in underwriting securities of other
issuers. Each of AIMCO and the AIMCO Operating Partnership intend to make
investments in such a way that it will not be treated as an investment company
under the Investment Company Act of 1940, as amended.
    
 
     The Company may invest in the securities of other issuers engaged in the
ownership, acquisition or management of multifamily apartment properties for the
purpose of exercising control.
 
     At all times, the Company intends to make investments in such a manner as
to be consistent with the requirements of the Code for AIMCO to qualify as a
REIT unless, because of changing circumstances or changes in the Code (or in
Treasury Regulations), the AIMCO Board determines that it is no longer in the
best interest of AIMCO to qualify as a REIT.
 
     AIMCO, as a REIT, is required to distribute annually to holders of Class A
Common Stock at least 95% of its "REIT taxable income," which, as defined by the
Code and the Treasury Regulations, is generally equivalent to net taxable
ordinary income. AIMCO measures its economic profitability, and intends to pay
regular dividends to its stockholders, based on earnings during the relevant
period. However, the future
                                       33
<PAGE>   146
 
payment of dividends by AIMCO will be at the discretion of the AIMCO Board and
will depend on numerous factors, including AIMCO's financial condition, its
capital requirements, the annual distribution requirements under the provisions
of the Code applicable to REITs and such other factors as the AIMCO Board deems
relevant.
 
RECENT PROPERTY ACQUISITIONS AND DISPOSITIONS
 
     During the year ended December 31, 1997, the Company purchased or acquired
control of 59 properties consisting of 17,191 apartment units. The cash portion
of the purchase price for the acquisitions was funded with proceeds from equity

     million in cash and the assumption of $7.8 million of mortgage
     indebtedness.
    
 
   
          Colony. Also in August 1998, the Company acquired Colony Apartments, a
     166-unit apartment community located in Bradenton, Florida. Total
     consideration paid was approximately $7.5 million, consisting of $4.1
     million in cash and the assumption of $3.4 million of mortgage
     indebtedness.
    
 
   
          Fisherman's Landing. In September 1998, the Company acquired
     Fisherman's Landing Apartments, a 256-unit apartment community located in
     Hillsborough County, Florida. Total consideration paid was approximately
     $11.0 million, consisting of $4.9 million in cash, 10,613 Common OP Units
     and the assumption of $5.7 million of mortgage indebtedness.
    
 
     Property Dispositions. In October 1997, the Company sold the Meadowbrook,
Ashwood, Parkside, Chimney Ridge and Cobble Creek apartment properties, which
consisted of an aggregate of 916 units located in Texas and Arizona, to an
unaffiliated third party. Cash proceeds from the sale of approximately $22.7
million were used to repay a portion of the Company's outstanding short-term
indebtedness. The Company recognized a gain of approximately $2.8 million on the
disposition of these five properties.
 
   
     In January 1998, the Company sold the Sun Valley Apartments, an apartment
community containing 430 apartment units located in Salt Lake City, Utah, for
$11.5 million, less selling costs of $0.3 million. The Company recognized a $3.3
million gain on the sale. Cash proceeds from the sale were used to repay a
portion of the AIMCO Operating Partnership's outstanding short-term
indebtedness.
    
 
   
     In September 1998, the Company sold the Rillito Village Apartments, an
apartment community containing 272 apartment units located in Tucson, Arizona,
for $6.8 million. The Company recognized a gain on the sale of approximately
$75,000 and used the cash proceeds to pay down a portion of the outstanding
balance on the Credit Facilities and to pay closing costs.
    
 
   
     Properties Subject to Letter of Intent or Contract. In the ordinary course
of the Company's business, the Company is engaged in discussions and
negotiations with property owners regarding the purchase of apartment properties
or interests in apartment properties. The Company frequently enters into letters
of intent, which may be binding or nonbinding, and contracts with respect to the
purchase of real property which are subject to certain conditions which permit
the Company to terminate the contract in its sole and absolute discretion if it
is not satisfied with the results of its due diligence investigation of the
properties under contract. The Company's management believes that such contracts
essentially result in the creation of an option on the property subject to the
contract and give the Company greater flexibility in seeking to acquire
properties. As of September 13, 1998, the Company had under letter of intent or
contract an aggregate of 56 multifamily apartment properties with a maximum
aggregate purchase price of $738 million, including estimated capital
improvements, which, in some cases, may be paid in the form of assumption of
existing debt. All such contracts are subject to termination by the Company as
described above. Due diligence with respect to these properties is generally not
completed and there is no assurance that any transaction will occur or that they
will occur on the terms currently contemplated.
    
 
   
YEAR 2000 COMPLIANCE
    
 
   
     The Company's management has determined that it will be necessary to modify
or replace certain accounting and operational software and hardware to enable
its computer systems to operate properly subsequent to December 31, 1999. As a
result, management has appointed a team of internal staff to research and manage
the conversion or replacement of existing systems to comply with year 2000
requirements. The
    
 
                                       35
<PAGE>   148
 
   
team's activities are designed to ensure that there is no adverse effect on the
Company's core business operations, and that transactions with tenants,
suppliers and financial institutions are fully supported.
    
 
   
     The Company utilizes numerous accounting and reporting software packages
and computer hardware to conduct its business, some of which already comply with
year 2000 requirements. Management estimates that the modification or
replacement of non-compliant accounting and reporting software and hardware will
total approximately $0.3 million.
    
 
   
     The Company's management also believes that certain of the Owned Properties
possess operational systems (e.g. elevators, fire alarm and extinguishment
systems and security systems) which also must be modified or replaced in order
to function properly in the 21st century. Management is currently engaged in the
identification of all non-compliant operational systems, and has not yet
determined the estimated cost of replacing or modifying such systems.
    
 
RECENT CONTRACTS
 
     On January 31, 1998, AIMCO entered into the CK Contribution Agreement with
CK and the stockholders of CK to cause certain assets of AIMCO to be contributed
to CK and to distribute all outstanding stock of CK to the stockholders of
AIMCO. CK is a corporation wholly-owned by Terry Considine, AIMCO's Chairman and
Chief Executive Officer, and Peter Kompaniez, AIMCO's President and Vice
Chairman.
 
     It is AIMCO's intent to use CK as a vehicle for holding property and
performing services that AIMCO is limited or prohibited from holding or
providing due to AIMCO's election to be taxed as a REIT. AIMCO is finalizing
which assets will be contributed to CK. Any transfer of assets or services to CK
will be at market rates and approved by the independent members of the AIMCO
Board, and if market rates are difficult to ascertain, there can be no assurance
that the pricing will favor AIMCO. It is anticipated that the assets to be
contributed to CK will be immaterial compared to total assets held by AIMCO.
 
     Pursuant to the CK Contribution Agreement, AIMCO will contribute certain
assets of AIMCO to CK and, in return, the stock of CK will be contributed to
AIMCO or a subsidiary of AIMCO. Following the contribution of CK stock, AIMCO
will agree to contribute additional assets to CK with the intent of creating a
stand-alone entity meeting the requirements for listing on the NYSE or NASDAQ
National Market, and if AIMCO is successful in listing the CK stock on the NYSE
or NASDAQ National Market, the stock of CK will be distributed to the
stockholders of AIMCO. If AIMCO is unable to list the CK stock on the NYSE or
NASDAQ National Market, CK will remain a direct or indirect subsidiary of AIMCO
and AIMCO will pay to the former stockholders of CK an amount necessary to
compensate the former CK stockholders for the value of such stock on January 31,
1998. No prediction can be made as to whether or when any spinoff to AIMCO
stockholders will occur. Consummation of the transaction is subject to the
approval of AIMCO's independent members of the AIMCO Board.
 
RECENT CREDIT AGREEMENTS
 
   
     In January 1998, the Company replaced its $100 million revolving credit
facility with Bank of America with a new $50 million unsecured credit facility
with Bank of America and BankBoston, N.A. (the "BOA Credit Facility"). The AIMCO
Operating Partnership is the borrower under the BOA Credit Facility, and all
obligations thereunder are guaranteed by AIMCO and certain of its subsidiaries.
On May 5, 1998, the AIMCO Operating Partnership entered into the Amended and
Restated Credit Agreement with Bank of America and the lenders from time to time
party thereto and increased its borrowing capacity under the BOA Credit Facility
to $155.0 million for a six-month period. At the conclusion of the six-month
period, the maximum borrowing capacity returns to its original $50.0 million.
The BOA Credit Facility expires on January 26, 2000, unless extended for
successive one-year periods, at the discretion of the lenders. The additional
borrowing capacity was used to facilitate the closing of the Ambassador Merger
and will be further utilized to complete the Insignia Merger.
    
 
                                       36
<PAGE>   149
 
     In February 1998, the AIMCO Operating Partnership, as borrower, and AIMCO
and certain single asset wholly-owned subsidiaries of AIMCO, as guarantors,
entered into the five year, $50 million secured WMF Credit Facility with
Washington Mortgage, which provides for the conversion of all or a portion of
such revolving credit facility to a base loan facility. The WMF Credit Facility
provides that all the rights of Washington Mortgage are assigned to FNMA, but
FNMA does not assume Washington Mortgage's obligations under the WMF Credit
Facility. At the Company's request, the commitment amount under the WMF Credit
Facility may be increased to an amount not to exceed $250 million, subject to
the consent of Washington Mortgage and FNMA in their sole and absolute
discretion. See "Risk Factors -- Risks of Significant Indebtedness."
 
                         DESCRIPTION OF PREFERRED STOCK
 
GENERAL
 
     AIMCO may issue, from time to time, shares of one or more series or classes
of Preferred Stock. The following description sets forth certain general terms
and provisions of the Preferred Stock to which any Prospectus Supplement may
relate. The particular terms of any series of Preferred Stock that may be issued
and sold pursuant hereto, and the extent, if any, to which such general
provisions may apply to the series of Preferred Stock so offered will be
described in the Prospectus Supplement relating to such Preferred Stock. The
following summary of certain provisions of the Preferred Stock do not purport to
be complete and is subject to, and is qualified in its entirety by express
reference to, the provisions of the Charter relating to a specific series of the
Preferred Stock, which will be in the form filed as an exhibit to or
incorporated by reference in the Registration Statement of which this Prospectus
is a part at or prior to the time of issuance of such series of Preferred Stock.
 
   
     The Charter authorizes the issuance of up to 510,750,000 shares of its
capital Stock. As of August 31, 1998, 496,027,500 shares were classified as
Class A Common Stock, 262,500 shares were classified as Class B Common Stock,
750,000 shares were classified as Class B Cumulative Convertible Preferred
Stock, par value $.01 per share ("Class B Preferred Stock"), 2,760,000 shares
were classified as Class C Cumulative Preferred Stock, par value $.01 per share
("Class C Preferred Stock"), 4,600,000 shares were classified as Class D
Cumulative Preferred Stock, par value $.01 per share ("Class D Preferred
Stock"), 4,050,000 shares were classified as Class G Cumulative Preferred Stock,
par value $.01 per share ("Class G Preferred Stock"), and 2,300,000 shares were
classified as Class H Cumulative Preferred Stock, par value $.01 per share
("Class H Preferred Stock"). Under the Charter, the AIMCO Board has the
authority to classify and reclassify any of its unissued capital Stock into
shares of Preferred Stock by setting or changing in any one or more respects the
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications or terms or conditions of redemption
of such shares of capital Stock including, but not limited to, ownership
restrictions consistent with the Ownership Limit with respect to each series or
class of capital Stock, and the number of shares constituting each series or
class, and to increase or decrease the number of shares of any such series or
class, to the extent permitted by the Maryland General Corporation Law (the
"MGCL").
    
 
     The AIMCO Board shall be authorized to determine for each series of
Preferred Stock, and the Prospectus Supplement shall set forth with respect to
each series that may be issued and sold pursuant hereto: (i) the designation of
such shares and the number of shares that constitute such series, (ii) the
dividend rate (or the method of calculation thereof), if any, on the shares of
such series and the priority as to payment of dividends with respect to other
classes or series of capital stock of AIMCO, (iii) the dividend periods (or the
method of calculation thereof), (iv) the voting rights of the shares, (v) the
liquidation preference and the priority as to payment of such liquidation
preference with respect to other classes or series of capital stock of AIMCO and
any other rights of the shares of such series upon any liquidation or winding-up
of AIMCO, (vi) whether or not and on what terms the shares of such series will
be subject to redemption or repurchase at the option of AIMCO, (vii) whether and
on what terms the shares of such series will be convertible into or exchangeable
for other debt or equity securities of AIMCO, (viii) whether the shares of such
series of Preferred Stock will be listed on a securities exchange, (ix) any
special United States federal income tax considerations applicable to such
series, and (x) the other rights and privileges and any qualifications,
                                       37
<PAGE>   150
 
limitations or restrictions of such rights or privileges of such series not
inconsistent with the Charter and the MGCL.
 
DIVIDENDS
 
     Holders of shares of Preferred Stock, shall be entitled to receive, when
and as declared by the AIMCO Board, out of funds of AIMCO legally available
therefor, an annual cash dividend payable at such dates and at such rates, if
any, per share per annum as set forth in the applicable Prospectus Supplement.
 
   
     Each series of Preferred Stock that may be issued and sold pursuant hereto,
will rank junior as to dividends to any Preferred Stock that may be issued in
the future that is expressly senior as to dividends to the Preferred Stock. If
at any time AIMCO has failed to pay accrued dividends on any such senior shares
at the time such dividends are payable, AIMCO may not pay any dividend on the
Preferred Stock or redeem or otherwise repurchase shares of Preferred Stock
until such accumulated but unpaid dividends on such senior shares have been paid
or set aside for payment in full by AIMCO.
    
 
   
     No dividends (other than in Class A Common Stock or Class B Common Stock
(collectively, the "Common Stock") or other capital Stock ranking junior to the
Preferred Stock of any series as to dividends and upon liquidation) shall be
declared or paid or set aside for payment, nor shall any other distribution be
declared or made upon the Common Stock, or any other capital stock of AIMCO
ranking junior to or on a parity with the Preferred Stock of such series as to
dividends, nor shall any Common Stock or any other capital stock of AIMCO
ranking junior to or on a parity with the Preferred Stock of such series as to
dividends or upon liquidation be redeemed, purchased or otherwise acquired for
any consideration (or any moneys be paid to or made available for a sinking fund
for the redemption of any shares of any such stock) by AIMCO (except by
conversion into or exchange for other capital stock of AIMCO ranking junior to
the Preferred Stock of such series as to dividends and upon liquidation) unless
(i) if such series of Preferred Stock has a cumulative dividend, full cumulative
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for all past dividend periods and the then current dividend period and
(ii) if such series of Preferred Stock does not have a cumulative dividend, full
dividends on the Preferred Stock of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for the then current dividend period; provided, however,
that any monies theretofore deposited in any sinking fund with respect to any
Preferred Stock in compliance with the provisions of such sinking fund may
thereafter be applied to the purchase or redemption of such Preferred Stock in
accordance with the terms of such sinking fund, regardless of whether at the
time of such application full cumulative dividends upon shares of the Preferred
Stock outstanding on the last dividend payment date shall have been paid or
declared and set apart for payment; and provided, further, that any such junior
or parity preferred stock or Common Stock may be converted into or exchanged for
stock of AIMCO ranking junior to the Preferred Stock as to dividends.
    
 
     The amount of dividends payable for the initial dividend period or any
period shorter than a full dividend period shall be computed on the basis of a
360-day year of twelve 30-day months. Accrued but unpaid dividends will not bear
interest.
 
CONVERTIBILITY
 
   
     The applicable Prospectus Supplement for each series of Preferred Stock
that may be issued and sold pursuant hereto will set forth the terms and
conditions of such series of Preferred Stock with respect to whether such series
of Preferred Stock will be convertible into, or exchangeable for, other
securities or property, including the initial conversion or exchange rate and
any adjustments thereto, the conversion or exchange period and any other
conversion or exchange provisions.
    
 
REDEMPTION AND SINKING FUND
 
   
     The applicable Prospectus Supplement for each series of Preferred Stock
that may be issued and sold pursuant hereto will set forth the terms and
conditions of such series of Preferred Stock with respect to
    
                                       38
<PAGE>   151
 
   
redemption rights and the benefit of any sinking fund, including the dates and
redemption prices of any such redemption, any conditions thereto, and any other
redemption or sinking fund provisions.
    
 
LIQUIDATION RIGHTS
 
   
     In the event of any liquidation, dissolution or winding up of AIMCO, the
holders of shares of each series of Preferred Stock that may be issued and sold
pursuant hereto are entitled to receive out of assets of AIMCO available for
distribution to stockholders, before any distribution of assets is made to
holders of: (i) any other shares of Preferred Stock ranking junior to such
series of Preferred Stock as to rights upon liquidation, dissolution or winding
up; and (ii) shares of Common Stock, liquidating distributions per share in the
amount of the liquidation preference specified in the applicable Prospectus
Supplement for such series of Preferred Stock plus any dividends accrued and
accumulated but unpaid to the date of final distribution; but the holders of
each series of Preferred Stock will not be entitled to receive the liquidating
distribution of, plus such dividends on, such shares until the liquidation
preference of any shares of AIMCO's capital stock ranking senior to such series
of the Preferred Stock as to the rights upon liquidation, dissolution or winding
up shall have been paid (or a sum set aside therefor sufficient to provide for
payment) in full. If upon any liquidation, dissolution or winding up of AIMCO,
the amounts payable with respect to the Preferred Stock, and any other Preferred
Stock ranking as to any such distribution on a parity with the Preferred Stock
are not paid in full, the holders of the Preferred Stock and such other parity
preferred stock will share ratably in any such distribution of assets in
proportion to the full respective preferential amount to which they are
entitled. After payment of the full amount of the liquidating distribution to
which they are entitled, the holders of shares of Preferred Stock will not be
entitled to any further participation in any distribution of assets by AIMCO.
Neither a consolidation or merger of AIMCO with another corporation nor a sale
of securities shall be considered a liquidation, dissolution or winding up of
AIMCO.
    
 
VOTING RIGHTS
 
   
     Holders of Preferred Stock that may be issued and sold pursuant hereto will
have the voting rights required by law and the voting rights described below.
Whenever dividends on any applicable series of Preferred Stock or any other
class or series of stock ranking on a parity with the applicable series of
Preferred Stock with respect to the payment of dividends shall be in arrears for
the equivalent of six quarterly dividend periods, whether or not consecutive,
the holders of shares of such series of Preferred Stock (voting separately as a
class with all other series of Preferred Stock then entitled to such voting
rights) will be entitled to vote for the election of two of the authorized
number of directors of AIMCO at the next annual meeting of stockholders and at
each subsequent meeting until all dividends accumulated on such series of
Preferred Stock shall have been fully paid or set apart for payment. The term of
office of all directors elected by the holders of such Preferred Stock shall
terminate immediately upon the termination of the right of the holders of such
Preferred Stock to vote for directors. Holders of shares of Preferred Stock that
may be issued and sold pursuant hereto will have one vote for each share held.
    
 
     So long as any shares of any series of Preferred Stock remain outstanding,
AIMCO shall not, without the consent of holders of at least two-thirds of the
shares of such series of Preferred Stock outstanding at the time, voting
separately as a class with all other series of Preferred Stock of AIMCO upon
which like voting rights have been conferred and are exercisable, (i) issue or
increase the authorized amount of any class or series of stock ranking prior to
the outstanding Preferred Stock as to dividends or upon liquidation or (ii)
amend, alter or repeal the provisions of the Charter relating to such series of
Preferred Stock, whether by merger, consolidation or otherwise, so as to
materially adversely affect any power, preference or special right of such
series of Preferred Stock or the holders thereof; provided, however, that any
increase in the amount of the authorized Common Stock or authorized Preferred
Stock or any increase or decrease in the number of shares of any series of
Preferred Stock or the creation and issuance of other series of Common Stock or
Preferred Stock ranking on a parity with or junior to Preferred Stock as to
dividends and upon liquidation, dissolution or winding up shall not be deemed to
materially adversely affect such powers, preferences or special rights.

MISCELLANEOUS
 
   
     The holders of Preferred Stock will have no preemptive rights. The
Preferred Stock that may be issued and sold pursuant hereto, upon issuance
against full payment of the purchase price therefor, will be fully paid and
nonassessable. Shares of Preferred Stock redeemed or otherwise reacquired by
AIMCO shall resume the status of authorized and unissued shares of Preferred
Stock undesignated as to series, and shall be available for subsequent issuance.
The applicable Prospectus Supplement will set forth the restrictions, if any, on
repurchase or redemption of the Preferred Stock while there is any arrearage on
sinking fund installments. Payment of dividends on, and the redemption or
repurchase of, any series of Preferred Stock may be restricted by loan
agreements, indentures and other agreements entered into by AIMCO. The
applicable Prospectus Supplement will describe any material contractual
restrictions on such dividend payments.
    
 
   
OTHER RIGHTS
    
 
   
     The shares of a series of Preferred Stock that may be issued and sold
pursuant hereto will have the preferences, voting powers or relative,
participating, optional or other special rights set forth above or in the
applicable Prospectus Supplement or the Charter or as otherwise required by law.
    
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for each series of Preferred Stock that
may be issued and sold pursuant hereto will be designated in the applicable
Prospectus Supplement.
 
CLASS B PREFERRED STOCK
 
   
     On August 4, 1997, AIMCO issued 750,000 shares of its Class B Preferred
Stock, to an institutional investor (the "Preferred Share Investor") in a
private transaction. The Class B Preferred Stock (a) ranks prior to the Common
Stock and will rank prior to the Class E Preferred Stock, if any, to be issued
in the Insignia Merger, with respect to dividends, liquidation, dissolution, and
winding-up, and has an aggregate liquidation value of $75 million and (b) ranks
on parity with the Class C Preferred Stock, the Class D Preferred Stock, the
Class G Preferred Stock, and the Class H Preferred Stock. Holders of the Class B
Preferred Stock are entitled to receive, when, as and if declared by the AIMCO
Board, quarterly cash dividends per share equal to the greater of (i) $1.78125
(the "Base Rate") and (ii) the cash dividends declared on the number of shares
of Class A Common Stock into which one share of Class B Preferred Stock is
convertible. On or after August 4, 1998, each share of Class B Preferred Stock
may be converted at the option of the holder into 3.28407 shares of Class A
Common Stock, subject to certain anti-dilution adjustments. AIMCO may redeem any
or all of the Class B Preferred Stock on or after August 4, 2002, at a
redemption price of $100 per share, plus unpaid dividends accrued on the shares
redeemed.
    
 
   
     Holders of Class B Preferred Stock, voting as a class with the holders of
all AIMCO capital stock that ranks on a parity with the Class B Preferred Stock
with respect to the payment of dividends or upon liquidation, dissolution,
winding up or otherwise ("Class B Parity Stock"), will be entitled to elect (i)
two directors of AIMCO if six quarterly dividends (regardless of whether
consecutive) on the Class B Preferred Stock or any Class B Parity Stock are in
arrears, and (ii) one director of AIMCO if for two consecutive quarterly
dividend periods AIMCO fails to pay at least $0.4625 in dividends on the Class A
Common Stock. The affirmative vote of the holders of two-thirds of the
outstanding shares of Class B Preferred Stock will be required to amend the
Charter in any manner that would adversely affect the rights of the holders of
Class B Preferred Stock, and to approve the issuance of any capital stock that
ranks senior to the Class B Preferred Stock with respect to payment of dividends
or upon liquidation, dissolution, winding up or otherwise. If the IRS were to
make a final determination that AIMCO does not qualify as a REIT in accordance
with Sections 856 through 860 of the Code, the Base Rate for the quarterly cash
dividends on the Class B Preferred Stock would increase to $3.03125 per share.
    
 
     The agreement pursuant to which AIMCO issued the Class B Preferred Stock
(the "Preferred Share Purchase Agreement") provides that the Preferred Share
Investor may require AIMCO to repurchase such investor's Class B Preferred Stock
in whole or in part at a price of 105% of the liquidation preference thereof,
                                       40
<PAGE>   153
 
plus accrued and unpaid dividends on the purchased shares, if (i) AIMCO shall
fail to continue to be taxed as a REIT pursuant to Sections 856 through 860 of
the Code, or (ii) upon the occurrence of a change of control (as defined in the
Preferred Share Purchase Agreement). The Preferred Share Purchase Agreement also
provides that, so long as the Preferred Share Investor owns Class B Preferred
Stock with an aggregate liquidation preference of at least $18.75 million,
neither AIMCO, the AIMCO Operating Partnership nor any subsidiary of AIMCO may
issue preferred securities or incur indebtedness for borrowed money if
immediately following such issuance and after giving effect thereto and the
application of the net proceeds therefrom, AIMCO's ratio of aggregate
consolidated earnings before interest, taxes, depreciation and amortization to
aggregate consolidated fixed charges for the four fiscal quarters immediately
preceding such issuance would be less than 1.5 to 1.
 
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class B Preferred Stock, no holder may own, or be
deemed to own by virtue of various attribution and constructive ownership
provisions of the Code and Rule 13d-3 under the Exchange Act, shares of Class B
Preferred Stock with a value in excess of the excess of (i) 8.7% (or 15% in the
case of certain pension trusts described in the Code, investment companies
registered under the Investment Company Act of 1940 and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO other than Class B Preferred Stock
that are owned by such holder (the "Class B Preferred Ownership Limit"). The
AIMCO Board may waive such ownership limit if evidence satisfactory to the AIMCO
Board and AIMCO's tax counsel is presented that such ownership will not then or
in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class B Preferred Stock in excess of the Class B
Preferred Ownership Limit, or shares of Class B Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee would acquire
no rights to the stock. Shares of Class B Preferred Stock transferred in excess
of the Class B Preferred Ownership Limit or other applicable limitations will
automatically be transferred to a trust for the exclusive benefit of one or more
qualifying charitable organizations to be designated by AIMCO. Shares
transferred to such trust will remain outstanding, and the trustee of the trust
will have all voting and dividend rights pertaining to such shares. The trustee
of such trust may transfer such shares to a person whose ownership of such
shares does not violate the Class B Preferred Ownership Limit or other
applicable limitation. Upon a sale of such shares by the trustee, the interest
of the charitable beneficiary will terminate, and the sales proceeds would be
paid, first, to the original intended transferee, to the extent of the lesser of
(a) such transferee's original purchase price (or the original market value of
such shares if purportedly acquired by gift or devise) and (b) the price
received by the trustee, and, second, any remainder to the charitable
beneficiary. In addition, shares of stock held in such trust are purchasable by
AIMCO for a 90-day period at a price equal to the lesser of the price paid for
the stock by the original intended transferee (or the original market value of
such shares if purportedly acquired by gift or devise) and the market price for
the stock on the date that AIMCO determines to purchase the stock. The 90-day
period commences on the date of the violative transfer or the date that the
AIMCO Board determines in good faith that a violative transfer has occurred,
whichever is later. All certificates representing shares of Class B Preferred
Stock bear a legend referring to the restrictions described above.
 
CLASS C PREFERRED STOCK
 
   
     On December 23, 1997, AIMCO issued 2,400,000 shares of its 9% Class C
Preferred Stock, in an underwritten public offering, for net proceeds of
approximately $57.9 million. The Class C Preferred Stock (a) ranks prior to the
Common Stock and will rank prior to the Class E Preferred Stock, if any, to be
issued in the Insignia Merger, and any other class or series of capital stock of
AIMCO if the holders of the Class C Preferred Stock are entitled to the receipt
of dividends and of amounts distributable upon liquidation, dissolution, and
winding-up in preference or priority to the holders of shares of such class or
series ("Class C Junior Stock"), (b) ranks on parity with the Class B Preferred

AIMCO if the holders of such class of stock or series and the Class C Preferred
Stock shall be entitled to the receipt of dividends and of amounts distributable
upon liquidation, dissolution or winding up in proportion to their respective
amounts of accrued and unpaid dividends per share or liquidation preferences,
without preference or priority one over the other ("Class C Parity Stock") and
(c) ranks junior to any class or series of capital stock of AIMCO if the holders
of such class or series shall be entitled to the receipt of dividends or amounts
distributable upon liquidation, dissolution or winding up in preference or
priority to the holders of the Class C Preferred Stock ("Class C Senior Stock").
 
     Holders of Class C Preferred Stock are entitled to receive cash dividends
at the rate of 9% per annum of the $25 liquidation preference (equivalent to
$2.25 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year. Upon any liquidation, dissolution or
winding up of AIMCO, before payment or distribution by AIMCO shall be made to or
set apart for the holders of any shares of Class C Junior Stock, the holders of
Class C Preferred Stock shall be entitled to receive a liquidation preference of
$25 per share (the "Class C Liquidation Preference"), plus an amount equal to
all accumulated, accrued and unpaid dividends to the date of final distribution
to such holders; but such holders shall not be entitled to any further payment.
If proceeds available for distribution shall be insufficient to pay the
preference described above and any liquidating payments on any other shares of
any class or series of Class C Parity Stock, then such proceeds shall be
distributed among the holders of Class C Preferred Stock and any such other
Class C Parity Stock ratably in the same proportion as the respective amounts
that would be payable on such Class C Preferred Stock and any such other Class C
Parity Stock if all amounts payable thereon were paid in full.
 
     On and after December 23, 2002, AIMCO may redeem shares of Class C
Preferred Stock, in whole or in part, at a cash redemption price equal to 100%
of the Class C Liquidation Preference plus all accrued and unpaid dividends to
the date fixed for redemption. The Class C Preferred Stock has no stated
maturity and will not be subject to any sinking find or mandatory redemption
provisions.
 
   
     Holders of shares of Class C Preferred Stock have no voting rights, except
that if distributions on Class C Preferred Stock or any series or class of Class
C Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class C Preferred Stock (voting together as a single class with all
other shares of Class C Parity Stock which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class C Preferred Stock called for such purpose. The
affirmative vote of the holders of two thirds of the outstanding shares of Class
C Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class C Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class C
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
    
 
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class C Preferred Stock, no holder may own shares
of Class C Preferred Stock with a value in excess of (i) 8.7% (or 15% in the
case of certain pension trusts described in the Code, investment companies
registered under the Investment Company Act of 1940 and Mr. Considine) of the
aggregate value of all shares of capital stock of AIMCO over (ii) the aggregate
value of all shares of capital stock of AIMCO other than Class C Preferred Stock
that are owned by such holder (the "Class C Preferred Ownership Limit"). The
AIMCO Board may waive such ownership limit if evidence satisfactory to the AIMCO
Board and AIMCO's tax counsel is presented that such ownership will not then or
in the future jeopardize AIMCO's status as a REIT. As a condition of such
waiver, the AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class C Preferred Stock in excess of the Class C
Preferred Ownership Limit, or shares of Class C Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee would acquire
no rights to the stock. Shares of Class C Preferred Stock transferred in excess
of the Class C Preferred Ownership Limit or other applicable limitations will
automatically be transferred to a trust for the exclusive
                                       42

benefit of one or more qualifying charitable organizations to be designated by
AIMCO. Shares transferred to such trust will remain outstanding, and the trustee
of the trust will have all voting and dividend rights pertaining to such shares.
The trustee of such trust may transfer such shares to a person whose ownership
of such shares does not violate the Class C Preferred Ownership Limit or other
applicable limitation. Upon a sale of such shares by the trustee, the interest
of the charitable beneficiary will terminate, and the sales proceeds would be
paid, first, to the original intended transferee, to the extent of the lesser of
(a) such transferee's original purchase price (or the original market value of
such shares if purportedly acquired by gift or devise) and (b) the price
received by the trustee, and, second, any remainder to the charitable
beneficiary. In addition, shares of stock held in such trust are purchasable by
AIMCO for a 90-day period at a price equal to the lesser of the price paid for
the stock by the original intended transferee (or the original market value of
such shares if purportedly acquired by gift or devise) and the market price for
the stock on the date that AIMCO determines to purchase the stock. The 90-day
period commences on the date of the violative transfer or the date that the
AIMCO Board determines in good faith that a violative transfer has occurred,
whichever is later. All certificates representing shares of Class C Preferred
Stock bear a legend referring to the restrictions described above.
 
CLASS D PREFERRED STOCK
 
   
     On February 19, 1998, AIMCO issued 4,200,000 shares of its 8 3/4% Class D
Preferred Stock, in an underwritten public offering, for net proceeds of
approximately $101.5 million. The Class D Preferred Stock (a) ranks prior to the
Common Stock and will rank prior to the Class E Preferred Stock, if any, to be
issued in the Insignia Merger, and any other class or series of capital stock of
AIMCO if the holders of the Class D Preferred Stock are to be entitled to the
receipt of dividends of or amounts distributable upon liquidation, dissolution,
and winding-up in preference or priority to the holders of shares of such class
or series ("Class D Junior Stock"), (b) ranks on parity with the Class B
Preferred Stock, the Class C Preferred Stock, the Class G Preferred Stock and
the Class H Preferred Stock, and with any other class or series of capital stock
of AIMCO if the holders of such class of stock or series and the Class D
Preferred Stock shall be entitled to the receipt of dividends and of amounts
distributable upon liquidation, dissolution or winding-up in proportion to their
respective amounts of accrued and unpaid dividends per share or liquidation
preferences, without preference or priority one over the other ("Class D Parity
Stock") and (c) ranks junior to any class or series of capital stock of AIMCO if
the holders of such class or series shall be entitled to the receipt of
dividends or amounts distributable upon liquidation, dissolution or winding up
in preference or priority to the holders of the Class D Preferred Stock ("Class
D Senior Stock").
    
 
     Holders of Class D Preferred Stock are entitled to receive cash dividends
at the rate of 8 3/4% per annum of the $25 liquidation preference (equivalent to
$2.1875 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year. Upon any liquidation, dissolution or
winding up of AIMCO, before payment or distribution by AIMCO shall be made to or
set apart for the holders of any shares of Class D Junior Stock, the holders of
Class D Preferred Stock shall be entitled to receive a liquidation preference of
$25 per share (the "Class D Liquidation Preference"), plus an amount equal to
all accumulated, accrued and unpaid dividends to the date of final distribution
to such holders; but such holders shall not be entitled to any further payment.
If proceeds available for distribution shall be insufficient to pay the
preference described above and any liquidating payments on any other shares of
any class or series of Class D Parity Stock, then such proceeds shall be
distributed among the holders of Class D Preferred Stock and any such other
Class D Parity Stock ratably in the same proportion as the respective amounts
that would be payable on such Class D Preferred Stock and any such other Class D
Parity Stock if all amounts payable thereon were paid in full.
 
     On and after February 19, 2003, AIMCO may redeem shares of Class D
Preferred Stock, in whole or in part, at a cash redemption price equal to 100%
of the Class D Liquidation Preference plus all accrued and unpaid dividends to
the date fixed for redemption. The Class D Preferred Stock has no stated
maturity and will not be subject to any sinking fund or mandatory redemption
provisions.
 
     Holders of shares of Class D Preferred Stock have no voting rights, except
that if distributions on Class D Preferred Stock or any series or class of Class
D Parity Stock shall be in arrears for six or more quarterly

periods, the number of directors constituting the AIMCO Board shall be increased
by two and the holders of Class D Preferred Stock (voting together as a single
class with all other shares of Class D Parity Stock which are entitled to
similar voting rights) will be entitled to vote for the election of the two
additional directors of AIMCO at any annual meeting of stockholders or at a
special meeting of the holders of the Class D Preferred Stock called for the
purpose. The affirmative vote of the holders of two-thirds of the outstanding
shares of Class D Preferred Stock will be required to amend the Charter in any
manner that would adversely affect the rights of the holders of Class D
Preferred Stock, and to approve the issuance of any capital stock that ranks
senior to the Class D Preferred Stock with respect to payment of dividends or
upon liquidation, dissolution, winding up or otherwise.
 
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class D Preferred Stock, no holder may own shares
of Class D Preferred Stock with a value in excess of the excess of (i) 8.7% (or
15% in the case of certain pension trusts described in the Code, investment
companies registered under the Investment Company Act of 1940 and Mr. Considine)
of the aggregate value of all shares of capital stock of AIMCO over (ii) the
aggregate value of all shares of capital stock of AIMCO other than Class D
Preferred Stock that are owned by such holder (the "Class D Preferred Ownership
Limit"). The AIMCO Board may waive such ownership limit if evidence satisfactory
to the AIMCO Board and AIMCO's tax counsel is presented that such ownership will
not then or in the future jeopardize AIMCO's status as a REIT. As a condition of
such waiver, AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class D Preferred Stock in excess of the Class D
Preferred Ownership Limit, or shares of Class D Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee would acquire
no rights to the stock. Shares of Class D Preferred Stock transferred in excess
of the Class D Preferred Ownership Limit or other applicable limitations will
automatically be transferred to a trust for the exclusive benefit of one or more
qualifying charitable organizations to be designated by AIMCO. Shares
transferred to such trust will remain outstanding, and the trustee of the trust
will have all voting and dividend rights pertaining to such shares. The trustee
of such trust may transfer such shares to a person whose ownership of such
shares does not violate the Class D Preferred Ownership Limit or other

Stock bear a legend referring to the restrictions described above.
 
CLASS E PREFERRED STOCK
 
   
     Upon consummation of the Insignia Merger, AIMCO will issue to Insignia
stockholders, in the aggregate, a number of shares of Class E Preferred Stock,
par value $.01 per share ("Class E Preferred Stock"), approximately equal to
$303 million divided by the AIMCO Index Price, less the Aggregate Cash Amount,
if any. The AIMCO Index Price is not intended to and will not necessarily
represent the fair market value of the AIMCO Class E Preferred Stock. The Class
E Preferred Stock (a) ranks prior to Common Stock, and any other class or series
of capital stock of AIMCO if holders of the Class E Preferred Stock are to be
entitled to the receipt of dividends or of amounts distributable upon
liquidation, dissolution, and winding-up in preference or priority to the
holders of shares of such class or series ("Class E Junior Stock"), (b) ranks on
a parity with any class or series of capital stock of AIMCO if the holders of
such class or series of stock and the Class E Preferred Stock shall be entitled
to the receipt of dividends and of amounts distributable upon

liquidation, dissolution or winding up in proportion to their respective amounts
of accrued and unpaid dividends per share or liquidation preferences, without
preference or priority one over the other ("Class E Parity Stock") and (c) ranks
junior to the Class B Preferred Stock, the Class C Preferred Stock, the Class D
Preferred Stock, the Class G Preferred Stock, the Class H Preferred Stock and
any other class or series of capital stock of AIMCO if the holders of such class
or series shall be entitled to the receipt of dividends or amounts distributable
upon liquidation, dissolution or winding up in preference or priority to the
holders of the Class E Preferred Stock ("Class E Senior Stock").
    
 
     On any date (each, a "Dividend Payment Date") on which cash dividends are
paid on the Class A Common Stock prior to the Class E Conversion Date (as
defined below), holders of Class E Preferred Stock are entitled to receive cash
dividends payable in an amount per share of Class E Preferred Stock equal to the
per share dividend payable on Class A Common Stock on such Dividend Payment
Date. Such dividends shall be cumulative from the date of original issue, and
shall be payable quarterly in arrears on the Dividend Payment Dates, commencing
on the first Dividend Payment Date after the date of original issue. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class E
Junior Stock, the holders of Class E Preferred Stock shall be entitled to
receive a liquidation preference of $1 per share plus the Special Dividend if
such dividend is unpaid on the date of the final distribution to such holders
(collectively, the "Class E Liquidation Preference"), and thereafter each share
of Class E Preferred Stock shall have the same rights with respect to assets of
AIMCO as one share of Class A Common Stock.
 
     On or after the twentieth anniversary of the Effective Time, AIMCO may
redeem shares of Class E Preferred Stock, in whole or in part, at a cash
redemption price equal to the sum of (i) the greater of (A) the Current Market
Price (as defined below) of the Class A Common Stock on the date specified for
redemption by AIMCO in a notice sent to holders of Class E Preferred Stock (the
"Class E Call Date") or (B) the AIMCO Index Price, but determined without giving
effect to the limitation of $38.00 per share, plus (ii) all accrued and unpaid
dividends to the Call Date. The Class E Preferred Stock has no stated maturity
and will not be subject to any sinking fund or mandatory redemption provisions.
 
     "Current Market Price" per share of Class A Common Stock on any date means
the average of the daily market prices of a share of Class A Common Stock for
the five consecutive trading days preceding such date. The market price for each
such day shall mean the last sale price, regular way, or, in case no such sale
takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the NYSE or, if the Class A Common Stock is not listed or admitted to
trading on the NYSE, as reported in the principal consolidated transaction
reporting system with respect to securities listed on the principal national
securities exchange on which the Class A Common Stock is listed or admitted to
trading or, if the Class A Common Stock is not listed or admitted to trading on
any national securities exchange, the last quoted price, or if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported by the National Association of Securities Dealers, Inc. Automated
Quotation System or, if such system is no longer in use, the principal other
automated quotations system that may then be in use or, if the Class A Common
Stock is not quoted by any such organization, the average of the closing bid and
asked prices as furnished by a professional market maker making a market in the
Class A Common Stock selected by the AIMCO Board.
 
     Holders of shares of Class E Preferred Stock shall be entitled to one-half
( 1/2) of one vote with respect to all matters in which holders of Class A
Common Stock shall be entitled to vote thereon. In addition, if any portion of
the Special Dividend has yet to be declared and paid to the holders of Class E
Preferred Stock on January 15, 1999, or if distributions on Class E Preferred
Stock or any series or class of Parity Stock shall be in arrears for six or more
quarterly periods, the number of directors constituting the AIMCO Board shall be
increased by two and the holders of Class E Preferred Stock (voting together as
a single class with all other shares of Class E Parity Stock which are entitled
to similar voting rights) will be entitled to vote for the election of such
additional directors. Such right shall continue until full cumulative dividends
for all past dividend periods on all shares of Preferred Stock, including any
shares of Class E Preferred Stock, have been paid or declared and set apart for
payment.
                                       45
<PAGE>   158
 
     On any date which the Special Dividend, or any portion thereof, is paid
(which may be declared by the AIMCO Board in its sole discretion), the holders
of Class E Preferred Stock shall be entitled to receive an amount per share of
Class E Preferred Stock equal to the Special Dividend divided by the Series E
Conversion Ratio (as defined in the Insignia Merger Agreement). After January
15, 1999, if any portion of the Special Dividend or any other dividend has yet
to be declared and paid to the holders of Class E Preferred Stock, no dividends
shall be declared or paid or set apart for payment by AIMCO on any other class
or series of AIMCO capital stock.
 
     On the close of business on the day on which the Special Dividend (or any
remaining unpaid portion thereof) is paid to the holders of the Class E
Preferred Stock, each share of Class E Preferred Stock will be automatically
converted into one share of Class A Common Stock without any action on the part
of AIMCO or the holder of such share (the "Class E Conversion Date"). If AIMCO
at any time following the Effective Time pays a dividend or makes a
distribution, subdivides, combines, reclassifies, issues rights, options or
warrants or makes any other distribution in securities in relation to its
outstanding Class A Common Stock, then AIMCO will contemporaneously do the same
with respect to the Class E Preferred Stock.
 
   
CLASS G PREFERRED STOCK
    
 
   
     On July 15, 1998, AIMCO issued 4,050,000 shares of its Class G Preferred
Stock, in an underwritten public offering for net proceeds of approximately
$98.0 million. The Class G Preferred Stock (a) ranks prior to the Common Stock
and will rank prior to the Class E Preferred Stock, if any, to be issued in the
Insignia Merger, and any other class or series of capital Stock of AIMCO, if the
holders of the Class G Preferred Stock are to be entitled to the receipt of
dividends or of amounts distributable upon liquidation, dissolution, and
winding-up in preference or priority to the holders of shares of such class or
series ("Class G Junior Stock"), (b) ranks on parity with the Class B Preferred
Stock, the Class C Preferred Stock, the Class D Preferred Stock and the Class H
Preferred Stock and with any other class or series of capital Stock of AIMCO, if
the holders of such class of Stock or series and the Class G Preferred Stock
shall be entitled to the receipt of dividends and of amounts distributable upon
liquidation, dissolution or winding-up in proportion to their respective amounts
of accrued and unpaid dividends per share or liquidation preferences, without
preference or priority one over the other ("Class G Parity Stock") and (c) ranks
junior to any class or series of capital Stock of AIMCO if the holders of such
class or series shall be entitled to the receipt of dividends or amounts
distributable upon liquidation, dissolution or winding-up in preference or
priority to the holders of the Class G Preferred Stock ("Class G Senior Stock").
    
 
     Holders of Class G Preferred Stock are entitled to receive cash dividends
at the rate of 9 3/8% per annum of the $25 liquidation preference (equivalent to
$2.34375 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing October 15, 1998. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class G
Junior Stock, the holders of Class G Preferred Stock shall be entitled to
receive a liquidation preference of $25 per share (the "Class G Liquidation
Preference"), plus an amount equal to all accumulated, accrued and unpaid
dividends to the date of final distribution to such holders; but such holders
shall not be entitled to any further payment. If proceeds available for
distribution shall be insufficient to pay the preference described above and any
liquidating payments on any other shares of any class or series of Class G
Parity Stock, then such proceeds shall be distributed among the holders of Class
G Preferred Stock and any such other Class G Parity Stock ratably in the same
proportion as the respective amount that would be payable on such Class G
Preferred Stock and any such other Class G Parity Stock if all amounts payable
thereon were paid in full.
 
     On and after July 15, 2008, AIMCO may redeem shares of Class G Preferred
Stock, in whole or in part, at a cash redemption price equal to 100% of the
Class G Liquidation Preference plus all accrued and unpaid dividends to the date
fixed for redemption. The Class G Preferred Stock has no stated maturity and
will not be subject to any sinking fund or mandatory redemption provisions.

     Holders of shares of Class G Preferred Stock have no voting rights, except
that if distributions on Class G Preferred Stock or any series or class of Class
G Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class G Preferred Stock (voting together as a single class with all
other shares of Class G Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class G Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
G Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class G Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class G
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
    
 
   
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class G Preferred Stock, no holder may own shares
of Class G Preferred Stock with a value in excess of the excess of (i) 8.7% (or
15% in the case of certain pension trusts described in the Code, investment
companies registered under the Investment Company Act of 1940 and Mr. Considine)
of the aggregate value of all shares of capital Stock of AIMCO over (ii) the
aggregate value of all shares of capital Stock of AIMCO other than Class G
Preferred Stock that are owned by such holder (the "Class G Preferred Ownership
Limit"). The AIMCO Board may waive such ownership limit if evidence satisfactory
to the AIMCO Board and AIMCO's tax counsel is presented that such ownership will
not then or in the future jeopardize AIMCO's status as a REIT. As a condition of
such waiver, the AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class G Preferred Stock in excess of the Class G
Preferred Ownership Limit, or shares of Class G Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee would acquire
no rights to the Stock. Shares of Class G Preferred Stock transferred in excess
of the Class G Preferred Ownership Limit or other applicable limitations will
automatically be transferred to a trust for the exclusive benefit of one or more
qualifying charitable organizations to be designated by AIMCO. Shares
transferred to such trust will remain outstanding, and the trustee of the trust
will have all voting and dividend rights pertaining to such shares. The trustee
of such trust may transfer such shares to a person whose ownership of such
shares does not violate the Class G Preferred Ownership Limit or other
applicable limitation. Upon a sale of such shares by the trustee, the interest
of the charitable beneficiary will terminate, and the sales proceeds would be
paid, first, to the original intended transferee, to the extent of the lesser of
(a) such transferee's original purchase price (or the original market value of
such shares if purportedly acquired by gift or devise) and (b) the price
received by the trustee, and, second, any remainder to the charitable
beneficiary. In addition, shares of Stock held in such trust are purchasable by
AIMCO for a 90-day period at a price equal to the lesser of the price paid for
the Stock by the original intended transferee (or the original market value of
such shares if purportedly acquired by gift or devise) and the market price for
the Stock on the date that AIMCO determines to purchase the Stock. The 90-day
period commences on the date of the violative transfer or the date that the
AIMCO Board determines in good faith that a violative transfer or the date that
the AIMCO Board determines in good faith that a violative transfer has occurred,
whichever is later. All certificates representing shares of Class G Preferred
Stock bear a legend referring to the restrictions described above.
    
 
   
CLASS H PREFERRED STOCK
    
 
   
     On August 11, 1998, AIMCO issued 2,000,000 shares of its Class H Preferred
Stock, in an underwritten public offering for net proceeds of approximately
$48.1 million. The Class H Preferred Stock (a) ranks prior to the Common Stock
and will rank prior to the Class E Preferred Stock, if any, to be issued in the
Insignia Merger, and any other class or series of capital Stock of AIMCO if the
holders of the Class H Preferred Stock are to be entitled to the receipt of
dividends or of amounts distributable upon liquidation, dissolution, and
winding-up in preference or priority to the holders of shares of such class or
series ("Class H Junior Stock"), (b) ranks on parity with the Class B Preferred

Stock and the Class G Preferred Stock, and with any other class or series of
capital Stock of AIMCO, if the holders of such class of Stock or series and the
Class G Preferred Stock shall be entitled to the receipt of dividends and of
amounts distributable upon liquidation, dissolution or winding-up in proportion
to their respective amounts of accrued and unpaid dividends per share or
liquidation preferences, without preference or priority one over the other
("Class H Parity Stock") and (c) ranks junior to any class or series of capital
Stock of AIMCO if the holders of such class or series shall be entitled to the
receipt of dividends or amounts distributable upon liquidation, dissolution or
winding-up in preference or priority to the holders of the Class H Preferred
Stock ("Class H Senior Stock").
    
 
   
     Holders of Class H Preferred Stock are entitled to receive cash dividends
at the rate of 9 1/2% per annum of the $25 liquidation preference (equivalent to
$2.375 per annum per share). Such dividends are cumulative from the date of
original issue, and are payable quarterly on or before January 15, April 15,
July 15 and October 15 of each year, commencing October 15, 1998. Upon any
liquidation, dissolution or winding up of AIMCO, before payment or distribution
by AIMCO shall be made to or set apart for the holders of any shares of Class H
Junior Stock, the holders of Class H Preferred Stock shall be entitled to
receive a liquidation preference of $25 per share (the "Class H Liquidation
Preference"), plus an amount equal to all accumulated, accrued and unpaid
dividends to the date of final distribution to such holders; but such holders
shall not be entitled to any further payment. If proceeds available for
distribution shall be insufficient to pay the preference described above and any
liquidating payments on any other shares of any class or series of Class H
Parity Stock, then such proceeds shall be distributed among the holders of Class
H Preferred Stock and any such other Class H Parity Stock ratably in the same
proportion as the respective amount that would be payable on such Class H
Preferred Stock and any such other Class H Parity Stock if all amounts payable
thereon were paid in full.
    
 
   
     On and after August 14, 2003, AIMCO may redeem shares of Class H Preferred
Stock, in whole or in part, at a cash redemption price equal to 100% of the
Class H Liquidation Preference plus all accrued and unpaid dividends to the date
fixed for redemption. The Class H Preferred Stock has no stated maturity and
will not be subject to any sinking fund or mandatory redemption provisions.
    
 
   
     Holders of shares of Class H Preferred Stock have no voting rights, except
that if distributions on Class H Preferred Stock or any series or class of Class
H Parity Stock shall be in arrears for six or more quarterly periods, the number
of directors constituting the AIMCO Board shall be increased by two and the
holders of Class H Preferred Stock (voting together as a single class with all
other shares of Class H Parity Stock, which are entitled to similar voting
rights) will be entitled to vote for the election of the two additional
directors of AIMCO at any annual meeting of stockholders or at a special meeting
of the holders of the Class H Preferred Stock called for the purpose. The
affirmative vote of the holders of two-thirds of the outstanding shares of Class
H Preferred Stock will be required to amend the Charter in any manner that would
adversely affect the rights of the holders of Class H Preferred Stock, and to
approve the issuance of any capital Stock that ranks senior to the Class H
Preferred Stock with respect to payment of dividends or upon liquidation,
dissolution, winding up or otherwise.
    
 
   
     Subject to certain exceptions specified in the provisions of the Charter
establishing the terms of the Class H Preferred Stock, no holder may own shares
of Class H Preferred Stock with a value in excess of the excess of (i) 8.7% (or
15% in the case of certain pension trusts described in the Code, investment
companies registered under the Investment Company Act of 1940 and Mr. Considine)
of the aggregate value of all shares of capital Stock of AIMCO over (ii) the
aggregate value of all shares of capital Stock of AIMCO other than Class H
Preferred Stock that are owned by such holder (the "Class H Preferred Ownership
Limit"). The AIMCO Board may waive such ownership limit if evidence satisfactory
to the AIMCO Board and AIMCO's tax counsel is presented that such ownership will
not then or in the future jeopardize AIMCO's status as a REIT. As a condition of
such waiver, the AIMCO Board may require opinions of counsel satisfactory to it
and/or an undertaking from the applicant with respect to preserving the REIT
status of AIMCO. If shares of Class H Preferred Stock in excess of the Class H
Preferred Ownership Limit, or shares of Class H Preferred Stock which would
result in AIMCO being "closely held," within the meaning of Section 856(h) of
the Code, or which would otherwise result in AIMCO failing to qualify as a REIT,
are issued or transferred to any person, such issuance or transfer will be null
and void to the intended transferee, and the intended transferee
    
                                       48
<PAGE>   161
 
   
would acquire no rights to the Stock. Shares of Class H Preferred Stock
transferred in excess of the Class H Preferred Ownership Limit or other
applicable limitations will automatically be transferred to a trust for the
exclusive benefit of one or more qualifying charitable organizations to be
designated by AIMCO. Shares transferred to such trust will remain outstanding,
and the trustee of the trust will have all voting and dividend rights pertaining
to such shares. The trustee of such trust may transfer such shares to a person
whose ownership of such shares does not violate the Class H Preferred Ownership
Limit or other applicable limitation. Upon a sale of such shares by the trustee,
the interest of the charitable beneficiary will terminate, and the sales
proceeds would be paid, first, to the original intended transferee, to the
extent of the lesser of (a) such transferee's original purchase price (or the
original market value of such shares if purportedly acquired by gift or devise)
and (b) the price received by the trustee, and, second, any remainder to the
charitable beneficiary. In addition, shares of Stock held in such trust are
purchasable by AIMCO for a 90-day period at a price equal to the lesser of the
price paid for the Stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the Stock on the date that AIMCO determines to purchase the
Stock. The 90-day period commences on the date of the violative transfer or the
date that the AIMCO Board determines in good faith that a violative transfer or
the date that the AIMCO Board determines in good faith that a violative transfer
has occurred, whichever is later. All certificates representing shares of Class
H Preferred Stock bear a legend referring to the restrictions described above.
    
 
                          DESCRIPTION OF COMMON STOCK
 
GENERAL
 
   
     The Charter authorizes the issuance of up to 510,750,000 shares of capital
Stock with a par value of $.01 per share, of which 496,027,500 shares were
classified as Class A Common Stock and 262,500 shares were classified as Class B
Common Stock as of August 31, 1998. As of August 31, 1998, there were 48,106,837
shares of Class A Common Stock issued and outstanding. In addition, up to
150,000 shares of Class A Common Stock have been reserved for issuance under
AIMCO's 1994 Stock Option Plan, up to 500,000 shares of Class A Common Stock
have been reserved for issuance under AIMCO's 1996 Stock Award and Incentive
Plan, and up to 500,000 shares of Class A Common Stock have been reserved for
issuance under AIMCO's Non-Qualified Stock Option Plan. Under AIMCO's 1997 Stock
Award and Incentive Plan, AIMCO may issue up to 10% of the shares of Class A
Common Stock outstanding as of the first day of the fiscal year during which any
award is made, but in no event more than 20,000,000 shares of Class A Common
Stock. The Class A Common Stock is traded on the NYSE under the symbol "AIV."
BankBoston, N.A. serves as transfer agent and registrar of the Class A Common
Stock. The Charter authorizes 750,000 shares of Class B Preferred Stock, all of
which are issued and outstanding, 2,760,000 shares of Class C Preferred Stock,
of which 2,400,000 shares are issued and outstanding, 4,600,000 shares of Class
D Preferred Stock, of which 4,200,000 shares are issued and outstanding,
4,050,000 shares of Class G Preferred Stock, of all of which shares are issued
and outstanding, and 2,300,000 shares of Class H Preferred Stock, of which
2,000,000 shares are issued and outstanding. In addition, the Charter authorizes
262,500 shares of Class B Common Stock, which number is subject to reduction by
the number of shares of Class B Common Stock that have been converted into
shares of Class A Common Stock. As of August 31, 1998, 162,500 shares of Class B
Common Stock were issued and outstanding. See "-- Class B Common Stock."
    
 
CLASS A COMMON STOCK
 
     Holders of the Class A Common Stock are entitled to receive dividends, when
and as declared by the AIMCO Board, out of funds legally available therefor. The
holders of shares of Class A Common Stock, upon any liquidation, dissolution or
winding up of AIMCO, are entitled to receive ratably any assets remaining after
payment in full of all liabilities of AIMCO and the liquidation preferences of
preferred stock. The shares of Class A Common Stock possess ordinary voting
rights for the election of Directors and in respect of other corporate matters,
each share entitling the holder thereof to one vote. Holders of shares of Class
A Common Stock do not have cumulative voting rights in the election of
Directors, which means that holders of more than
 
                                       49
<PAGE>   162
 
50% of the shares of Class A Common Stock voting for the election of Directors
can elect all of the Directors if they choose to do so and the holders of the
remaining shares cannot elect any Directors. Holders of shares of Class A Common
Stock do not have preemptive rights, which means they have no right to acquire
any additional shares of Class A Common Stock that may be issued by AIMCO at a
subsequent date.
 
RESTRICTIONS ON TRANSFER
 
   
     For AIMCO to qualify as a REIT under the Code, not more than 50% in value
of its outstanding capital stock may be owned, directly or indirectly, by five
or fewer individuals (as defined in the Code to include certain entities) during
the last half of a taxable year and the shares of capital stock must be
beneficially owned by 100 or more persons during at least 335 days of a taxable
year of 12 months or during a proportionate part of a shorter taxable year.
Because the AIMCO Board believes that it is essential for AIMCO to continue to
qualify as a REIT and to provide additional protection for AIMCO's stockholders
in the event of certain transactions, the AIMCO Board has adopted, and the
stockholders have approved, provisions of the Charter restricting the
acquisition of shares of Common Stock.
    
 
   
     Subject to certain exceptions specified in the Charter, no holder may own,
or be deemed to own by virtue of various attribution and constructive ownership
provisions of the Code and Rule 13d-3 under the Exchange Act, more than 8.7% (or
15% in the case of certain pension trusts described in the Code, investment
companies registered under the Investment Company Act of 1940 and Mr. Considine)
of the outstanding shares of Common Stock. For purposes of calculating the
amount of stock owned by a given individual, the individual's Common Stock and
Common OP Units are aggregated. The AIMCO Board may waive the Ownership Limit if
evidence satisfactory to the AIMCO Board and AIMCO's tax counsel is presented
that such ownership will not then or in the future jeopardize AIMCO's status as
a REIT. However, in no event may such holder's direct or indirect ownership of
Common Stock exceed 9.8% of the total outstanding shares of Common Stock. As a
condition of such waiver, the AIMCO Board may require opinions of counsel
satisfactory to it and/or an undertaking from the applicant with respect to
preserving the REIT status of AIMCO. The foregoing restrictions on
transferability and ownership will not apply if the AIMCO Board determines that
it is no longer in the best interests of AIMCO to attempt to qualify, or to
continue to quality as a REIT and a resolution terminating AIMCO's status as a
REIT and amending the Charter to remove the foregoing restrictions is duly
adopted by the AIMCO Board and a majority of AIMCO's stockholders. If shares of
Common Stock in excess of the Ownership Limit, or shares of Common Stock which
would cause the REIT to be beneficially owned by fewer than 100 persons, or
which would result in AIMCO being "closely held," within the meaning of Section
856(h) of the Code, or which would otherwise result in AIMCO failing to qualify
as a REIT, are issued or transferred to any person, such issuance or transfer
shall be null and void to the intended transferee, and the intended transferee
would acquire no rights to the stock. Shares of Common Stock transferred in
excess of the Ownership Limit or other applicable limitations will automatically
be transferred to a trust for the exclusive benefit of one or more qualifying
charitable organizations to be designated by AIMCO. Shares transferred to such
trust will remain outstanding, and the trustee of the trust will have all voting
and dividend rights pertaining to such shares. The trustee of such trust may
transfer such shares to a person whose ownership of such shares does not violate
the Ownership Limit or other applicable limitation. Upon a sale of such shares
by the trustee, the interest of the charitable beneficiary will terminate, and
the sales proceeds would be paid, first, to the original intended transferee, to
the extent of the lesser of (a) such transferee's original purchase price (or
the original market value of such shares if purportedly acquired by gift or
devise) and (b) the price received by the trustee, and, second, any remainder to
the charitable beneficiary. In addition, shares of stock held in such trust are
purchasable by AIMCO for a 90-day period at a price equal to the lesser of the
price paid for the stock by the original intended transferee (or the original
market value of such shares if purportedly acquired by gift or devise) and the
market price for the stock on the date that AIMCO determines to purchase the
stock. The 90-day period commences on the date of the violative transfer or the
date that the AIMCO Board determines in good faith that a violative transfer has
occurred, whichever is later. All certificates representing shares of Common
Stock bear a legend referring to the restrictions described above.
    
 
                                       50
<PAGE>   163
 
     All persons who own, directly or by virtue of the attribution provisions of
the Code and Rule 13d-3 under the Exchange Act, more than a specified percentage
of the outstanding shares of Common Stock must file a written statement or an
affidavit with AIMCO containing the information specified in the Charter within
30 days after January 1 of each year. In addition, each stockholder shall upon
demand be required to disclose to AIMCO in writing such information with respect
to the direct, indirect and constructive ownership of shares as the AIMCO Board
deems necessary to comply with the provisions of the Code applicable to a REIT
or to comply with the requirements of any taxing authority or governmental
agency.
 
     The ownership limitations may have the effect of precluding acquisition of
control of AIMCO by a third party unless the AIMCO Board determines that
maintenance of REIT status is no longer in the best interests of AIMCO.
 
CLASS B COMMON STOCK
 
     In connection with the initial formation of AIMCO, Terry Considine, Peter
Kompaniez, Steven Ira and Robert P. Lacy (a former officer of AIMCO) acquired an
aggregate of 650,000 shares of Class B Common Stock. The Charter, which
initially authorized 750,000 shares of Class B Common Stock, was amended in June
1998 to authorize 262,500 shares of Class B Common Stock, of which 162,500
shares are issued and outstanding. The Class B Common Stock does not have voting
or dividend rights and, unless converted into Class A Common Stock, as described
below, is subject to repurchase by AIMCO as described below. As of December 31
of each of the years 1994 through 1998 (each, a "Year-End Testing Date"), a
number of the shares of Class B Common Stock outstanding as of such date (the
"Eligible Class B Shares") become eligible for automatic conversion (subject to
the Ownership Limit) into an equal number of shares of Class A Common Stock
(subject to adjustment upon the occurrence of certain events in respect of the
Class A Common Stock, including stock dividends, subdivisions, combinations and
reclassifications). Once Class B Common Stock has been converted into Class A
Common Stock, holders of such shares of converted Class A Common Stock will have
voting and dividend rights of Class A Common Stock generally. Once converted or
forfeited, the Class B Common Stock may not be reissued by AIMCO.
 
     The Eligible Class B Shares convert to Class A Common Stock if (i) AIMCO's
Funds from Operations Per Share (as defined below) reaches certain annual and
cumulative growth targets and (ii) the average market price for a share of Class
A Common Stock for a 90 calendar day period beginning on any day on or after the
October 1 immediately preceding the relevant Year-End Testing Date equals or
exceeds a specified target price. "Funds from Operations Per Share" or "FFO Per
Share" means, for any period, (i) net income (loss), computed in accordance with
generally accepted accounting principles, excluding gains (or losses) from debt
restructuring and sales of property, plus depreciation and amortization, and
after adjustments for unconsolidated partnerships and joint ventures, less any
preferred stock dividend payments, divided by (ii) the sum of (a) the number of
shares of the Class A Common Stock outstanding on the last day of such period
(excluding any shares of the Class A Common Stock into which shares of the Class
B Common Stock shall have been converted as a result of the conversion of shares
of the Class B Common Stock on the last day of such period) and (b) the number
of shares of the Class A Common Stock issuable to acquire units of limited
partnership that (x) may be tendered for redemption in any limited partnership
in which AIMCO serves as general partner and (y) are outstanding on the last day
of such period.
 
     Set forth below for each of the remaining Year-End Testing Dates is (i) the
number of shares of Class B Common Stock that become Eligible Class B Shares as
of such date, (ii) the annual FFO Per Share growth target (as a percentage
increase in FFO Per Share from the prior year), (iii) the cumulative FFO Per
Share growth target (in FFO Per Share) and (iv) the average market price target:

     If the annual growth target is not met for a particular Year-End Testing
Date, the Eligible Class B Shares for that date may be converted as of a
subsequent Year-End Testing Date if all of the targets are met for that
subsequent Year-End Testing Date. Any Class B Common Stock that has not been
converted into Class A Common Stock following December 31, 1998 will be subject
to repurchase by AIMCO at a price of $0.10 per share. Class B Common Stock is
also subject to automatic conversion upon the occurrence of certain events,
including a change of control (as defined in the Charter). The AIMCO Board may
increase the number of shares which are eligible for conversion as of any
Year-End Testing Date and may, under certain circumstances, accelerate the
conversion of outstanding Class B Common Stock at such time and in such amount
as it may determine appropriate.
    
 
     All of the 65,000 shares of Class B Common Stock eligible for conversion as
of the December 31, 1994 Year-End Testing Date, all of the 130,000 shares of
Class B Common Stock eligible for conversion as of the December 31, 1995
Year-End Testing Date, all of the 130,000 shares of Class B Common Stock
eligible for conversion as of December 31, 1996 and all of the 162,500 shares of
Class B Common Stock eligible for conversion as of December 31, 1997, have been
converted into shares of Class A Common Stock. As of December 31, 1997, the
outstanding Class B Common Stock was held as follows: 93,428 shares by Mr.
Considine, 41,438 shares by Mr. Kompaniez, 13,821 shares by Mr. Ira and 13,813
shares by Mr. Lacy.
 
BUSINESS COMBINATIONS
 
     Under the MGCL, certain "business combinations" (including a merger,
consolidation, share exchange or, in certain circumstances, an asset transfer or
issuance or reclassification of equity securities) between a Maryland
corporation and any person who beneficially owns 10% or more of the voting power
of the corporation's shares or an affiliate of the corporation who, at any time
within the two-year period prior to the date in question, was the beneficial
owner of 10% or more of the voting power of the then-outstanding voting stock of
the corporation (an "Interested Stockholder") or an affiliate thereof are
prohibited for five years after the most recent date on which the Interested
Stockholder became an Interested Stockholder. Thereafter, any such business
combination must be recommended by the board of directors of the corporation and
approved by the affirmative vote of at least (a) 80% of the votes entitled to be
cast by holders of outstanding voting shares of the corporation, voting together
as a single voting group, and (b) two-thirds of the votes entitled to be cast by
holders of outstanding voting shares of the corporation other than shares held
by the Interested Stockholder or an affiliate of the Interested Stockholder with
whom the business combination is to be effected, unless, among other conditions,
the corporation's stockholders receive a minimum price (as defined in the MGCL)
for their shares and the consideration is received in cash or in the same form
as previously paid by the Interested Stockholder for its shares. For purposes of
determining whether a person is an Interested Stockholder, ownership of Common
OP Units will be treated as beneficial ownership of the shares of Common Stock
for which the Common OP Units may be redeemed. The business combination statute
could have the effect of discouraging offers to acquire AIMCO and of increasing
the difficulty of consummating any such offer. These provisions of the MGCL do
not apply, however, to business combinations that are approved or exempted by
the board of directors of the corporation prior to the time that the Interested
Stockholder becomes an Interested Stockholder. The AIMCO Board has not passed
such a resolution.
 
CONTROL SHARE ACQUISITIONS
 
     The MGCL provides that "control shares" of a Maryland corporation acquired
in a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter,
excluding shares of stock owned by the acquiror or by officers or directors who
are employees of the corporation. "Control shares" are voting shares of stock
that, if aggregated with all other shares of stock previously acquired by that
person, would entitle the acquiror to exercise voting power in electing
directors within one of the following ranges of voting power: (i) one-fifth or
more but less than one-third, (ii) one-third or more but less than a majority or
(iii) a majority or more of all voting power. Control shares do not include
shares the acquiring person is then entitled to vote as a result of having
previously obtained stockholder approval.
 
                                       52
<PAGE>   165
 
     A "control share acquisition" means the acquisition of control shares,
subject to certain exceptions. A person who has made or proposes to make a
control share acquisition, upon satisfaction of certain conditions (including an
undertaking to pay expenses), may compel the corporation's board of directors to
call a special meeting of stockholders, to be held within 50 days of demand, to
consider the voting rights of the shares. If no request for a meeting is made,
the corporation may itself present the question at any stockholders meeting.
 
     If voting rights are not approved at the meeting or if the acquiring person
does not deliver an "acquiring person statement" as required by the statute,
then, subject to certain conditions and limitations, the corporation may redeem
any or all of the control shares (except those for which voting rights have
previously been approved) for fair value determined, without regard to the
absence of voting rights, as of the date of the last control share acquisition
or of any meeting of stockholders at which the voting rights of such shares were
considered and not approved. If voting rights for control shares are approved at
a stockholders meeting and the acquiror becomes entitled to vote a majority of
the shares entitled to vote, all other stockholders may exercise appraisal
rights. The fair value of the shares as determined for purposes of the appraisal
rights may not be less than the highest price per share paid in the control
share acquisition, and certain limitations and restrictions otherwise applicable
to the exercise of dissenters' rights do not apply in the context of a control
share acquisition.
 
     The control share acquisition statute does not apply to shares acquired in
a merger, consolidation or share exchange if the corporation is a party to the
transaction, or to acquisitions approved or exempted by the corporation's
articles of incorporation or bylaws prior to the control share acquisition. No
such exemption appears in the Charter or in AIMCO's bylaws (the "Bylaws"). The
control share acquisition statute could have the effect of discouraging offers
to acquire AIMCO and of increasing the difficulty of consummating any such
offer.
 
                            DESCRIPTION OF OP UNITS
 
     The following description sets forth certain general terms and provisions
of the OP Units and the AIMCO Operating Partnership Agreement. The AIMCO
Operating Partnership Agreement is included as Appendix B-1 hereto, and this
description is qualified in its entirety by the terms thereof.
 
GENERAL
 
     The AIMCO Operating Partnership is a limited partnership organized pursuant
to the provisions of the Delaware Revised Uniform Limited Partnership Act (as
amended from time to time, or any successor to such statute, the "Delaware LP
Act") and upon the terms and subject to the conditions set forth in the AIMCO
Operating Partnership Agreement. AIMCO GP, a Delaware corporation and a wholly
owned subsidiary of AIMCO, is the sole general partner of the AIMCO Operating
Partnership. Another wholly owned subsidiary of AIMCO, the Special Limited
Partner, is a limited partner in the AIMCO Operating Partnership. The term of
the AIMCO Operating Partnership commenced on May 16, 1994, and will continue
until December 31, 2093, unless the AIMCO Operating Partnership is dissolved
sooner pursuant to the provisions of the AIMCO Operating Partnership Agreement
or as otherwise provided by law.
 
PURPOSE AND BUSINESS
 
     The purpose and nature of the AIMCO Operating Partnership is to conduct any
business, enterprise or activity permitted by or under the Delaware LP Act,
including, but not limited to, (i) to conduct the business of ownership,
construction, development and operation of multifamily rental apartment
communities, (ii) to enter into any partnership, joint venture, business trust
arrangement, limited liability company or other similar arrangement to engage in
any business permitted by or under the Delaware LP Act, or to own interests in
any entity engaged in any business permitted by or under the Delaware LP Act,
(iii) to conduct the business of providing property and asset management and
brokerage services, whether directly or through one or more partnerships, joint
ventures, subsidiaries, business trusts, limited liability companies or other
similar arrangements, and (iv) to do anything necessary or incidental to the
foregoing; provided, however, such business and arrangements and interests may
be limited to and conducted in such a manner as to permit AIMCO, in the sole and
absolute discretion of the AIMCO GP, at all times to be classified as a REIT.

<PAGE>   166
 
MANAGEMENT BY THE AIMCO GP
 
   
     Except as otherwise expressly provided in the AIMCO Operating Partnership
Agreement, all management powers over the business and affairs of the AIMCO
Operating Partnership are exclusively vested in the AIMCO GP. None of the
limited partners of the AIMCO Operating Partnership or any other person to whom
one or more OP Units have been transferred (each, an "Assignee") will take part
in the operations, management or control (within the meaning of the Delaware LP
Act) of the AIMCO Operating Partnership's business, transact any business in the
AIMCO Operating Partnership's name or have the power to sign documents for or
otherwise bind the AIMCO Operating Partnership. The AIMCO GP may not be removed
by the OP Unitholders with or without cause, except with the consent of the
AIMCO GP. In addition to the powers granted a general partner of a limited
partnership under applicable law or that are granted to the AIMCO GP under any
other provision of the AIMCO Operating Partnership Agreement, the AIMCO GP,
subject to the other provisions of the AIMCO Operating Partnership Agreement,
has full power and authority to do all things deemed necessary or desirable by
it to conduct the business of the AIMCO Operating Partnership, to exercise all
powers of the AIMCO Operating Partnership and to effectuate the purposes of the
AIMCO Operating Partnership. The AIMCO Operating Partnership may incur debt or
enter into other similar credit, guarantee, financing or refinancing
arrangements for any purpose (including, without limitation, in connection with
any acquisition of properties) upon such terms as the AIMCO GP determines to be
appropriate. The AIMCO GP is authorized to execute, deliver and perform certain
agreements and transactions on behalf of the AIMCO Operating Partnership without
any further act, approval or vote of the OP Unitholders.
    
 
   
     Restrictions on AIMCO GP's Authority. The AIMCO GP may not take any action
in contravention of the AIMCO Operating Partnership Agreement. The AIMCO GP may
not, without the prior consent of the OP Unitholders, undertake, on behalf of
the AIMCO Operating Partnership, any of the following actions or enter into any
transaction that would have the effect of such transactions: (i) except as
provided in the AIMCO Operating Partnership Agreement, amend, modify or
terminate the AIMCO Operating Partnership Agreement other than to reflect the
admission, substitution, termination or withdrawal of OP Unitholders; (ii) make
a general assignment for the benefit of creditors or appoint or acquiesce in the
appointment of a custodian, receiver or trustee for all or any part of the
assets of the AIMCO Operating Partnership; (iii) institute any proceeding for
bankruptcy on behalf of the AIMCO Operating Partnership; or (iv) subject to
certain exceptions, approve or acquiesce to the transfer of the AIMCO Operating
Partnership interest of the AIMCO GP, or admit into the AIMCO Operating
Partnership any additional or successor general partners of the AIMCO Operating
Partnership.
    
 
   
     Issuance of Additional OP Limited Partnership Interests. The AIMCO GP is
authorized to admit additional limited partners to the AIMCO Operating
Partnership from time to time, on terms and conditions and for such capital
contributions as may be established by the AIMCO GP in its reasonable
discretion. The net capital contribution need not be equal for all OP
Unitholders. No action or consent by the OP Unitholders is required in
connection with the admission of any additional OP Unitholder. The AIMCO GP is
expressly authorized to cause the AIMCO Operating Partnership to issue
additional interests (i) upon the conversion, redemption or exchange of any
debt, OP Units or other securities issued by the AIMCO Operating Partnership,
(ii) for less than fair market value, so long as the AIMCO GP concludes in good
faith that such issuance is in the best interests of the AIMCO GP and the AIMCO
Operating Partnership, and (iii) in connection with any merger of any other
entity into the AIMCO Operating Partnership if the applicable merger agreement
provides that persons are to receive interests in the AIMCO Operating
Partnership in exchange for their interests in the entity merging into the AIMCO
Operating Partnership. Subject to Delaware law, any additional partnership
interests may be issued in one or more classes, or one or more series of any of
such classes, with such designations, preferences and relative, participating,
optional or other special rights, powers and duties as shall be determined by
the AIMCO GP, in its sole and absolute discretion without the approval of any OP
Unitholder, and set forth in a written document thereafter attached to and made
an exhibit to the AIMCO Operating Partnership Agreement. Without limiting the
generality of the foregoing, the AIMCO GP shall have authority to specify (a)
the allocations of items of partnership income, gain, loss, deduction and credit
to each such class or series of partnership interests; (b) the right of each
such class or
    
 
                                       54
<PAGE>   167
 
   
series of partnership interests to share in distributions by the AIMCO Operating
Partnership; (c) the rights of each such class or series of partnership
interests upon dissolution and liquidation of the AIMCO Operating Partnership;
(d) the voting rights, if any, of each such class or series of partnership
interests; and (e) the conversion, redemption or exchange rights applicable to
each such class or series of partnership interests. Interests in the AIMCO
Operating Partnership that have distribution rights, or rights upon liquidation,
winding up or dissolution, that are superior or prior to the Common OP Units are
Preferred OP Units. No person will be admitted as an additional OP Unitholder
without the consent of the AIMCO GP, which consent may be given or withheld in
the AIMCO GP's sole and absolute discretion.
    
 
MANAGEMENT LIABILITY AND INDEMNIFICATION
 
     Notwithstanding anything to the contrary set forth in the AIMCO Operating
Partnership Agreement, the AIMCO GP is not liable to the AIMCO Operating
Partnership for losses sustained, liabilities incurred or benefits not derived
as a result of errors in judgment or mistakes of fact or law of any act or
omission if the AIMCO GP acted in good faith. The AIMCO Operating Partnership
Agreement provides for indemnification of AIMCO, or any director or officer of
AIMCO (in its capacity as the previous general partner of the AIMCO Operating
Partnership), the AIMCO GP, any officer or director of AIMCO GP or the AIMCO
Operating Partnership and such other persons as the AIMCO GP may designate from
and against all losses, claims, damages, liabilities, joint or several, expenses
(including legal fees), fines, settlements and other amounts incurred in
connection with any actions relating to the operations of the AIMCO Operating
Partnership, as set forth in the AIMCO Operating Partnership Agreement. The
Delaware Revised Uniform Limited Partnership Act provides that subject to the
standards and restrictions, if any, set forth in its partnership agreement, a
limited partnership may, and shall have the power to, indemnify and hold
harmless any partner or other person from and against any and all claims and
demands whatsoever. It is the position of the Commission that indemnification of
directors and officers for liabilities arising under the Securities Act is
against public policy and is unenforceable pursuant to Section 14 of the
Securities Act.
 
COMPENSATION AND FEES
 
     The AIMCO GP does not receive compensation for its services as general
partner of the AIMCO Operating Partnership. However, the AIMCO GP is entitled to
payments, allocations and distributions in its capacity as general partner of
the AIMCO Operating Partnership. In addition, the AIMCO Operating Partnership is
responsible for all expenses incurred relating to the AIMCO Operating
Partnership's ownership of its assets and the operation of the AIMCO Operating
Partnership and reimburses the AIMCO GP for such expenses paid by the AIMCO GP.
The employees of the AIMCO Operating Partnership receive compensation for their
services.
 
FIDUCIARY RESPONSIBILITIES
 
     The directors and officers of the AIMCO GP have fiduciary duties to manage
the AIMCO GP in a manner beneficial to AIMCO, as the sole stockholder of the
AIMCO GP. At the same time, the AIMCO GP, as general partner, has fiduciary
duties to manage the AIMCO Operating Partnership in a manner beneficial to the
AIMCO Operating Partnership and its partners. The duties of the AIMCO GP, as
general partner, to the AIMCO Operating Partnership and its partners, therefore,
may come into conflict with the duties of the directors and officers of the
AIMCO GP to its sole stockholder, AIMCO.
 
     Unless otherwise provided for in the relevant partnership agreement,
Delaware law generally requires a general partner of a Delaware limited
partnership to adhere to fiduciary duty standards under which it owes its
limited partners the highest duties of good faith, fairness and loyalty and
which generally prohibit such general partner from taking any action or engaging
in any transaction as to which it has a conflict of interest. The AIMCO
Operating Partnership Agreement expressly authorizes the AIMCO GP to enter into,
on behalf of the AIMCO Operating Partnership, a right of first opportunity
arrangement and other conflict avoidance agreements with various affiliates of
the AIMCO Operating Partnership and the AIMCO GP, on such terms as the AIMCO GP,
in its sole and absolute discretion, believes are advisable. The latitude given
in the AIMCO Operating Partnership Agreement to the AIMCO GP in resolving
conflicts of interest may
                                       55
<PAGE>   168
 
   
significantly limit the ability of an OP Unitholder to challenge what might
otherwise be a breach of fiduciary duty. The AIMCO GP believes, however, that
such latitude is necessary and appropriate to enable it to serve as the general
partner of the AIMCO Operating Partnership without undue risk of liability.
    
 
     The AIMCO Operating Partnership Agreement expressly limits the liability of
the AIMCO GP by providing that the AIMCO GP, and its officers and directors will
not be liable or accountable in damages to the AIMCO Operating Partnership, the
limited partners or assignees for errors in judgment or mistakes of fact or law
or of any act or omission if the AIMCO GP or such director or officer acted in
good faith. In addition, the AIMCO Operating Partnership is required to
indemnify the AIMCO GP, its affiliates and their respective officers, directors,
employees and agents to the fullest extent permitted by applicable law, against
any and all losses, claims, damages, liabilities, joint or several, expenses,
judgments, fines and other actions incurred by the AIMCO GP or such other
persons, provided that the AIMCO Operating Partnership will not indemnify for
(i) willful misconduct or a knowing violation of the law or (ii) for any
transaction for which such person received an improper personal benefit in
violation or breach of any provision of the AIMCO Operating Partnership
Agreement.
 
     The provisions of Delaware law that allow the common law fiduciary duties
of a general partner to be modified by a partnership agreement have not been
resolved in a court of law, and the AIMCO GP has not obtained an opinion of
counsel covering the provisions set forth in the AIMCO Operating Partnership
Agreement that purport to waive or restrict the fiduciary duties of the AIMCO GP
that would be in effect under common law were it not for the AIMCO Operating
Partnership Agreement. See "Risk Factors -- Risks Associated With an Investment
in OP Units -- Conflicts of Interest and Fiduciary Responsibility."
 
CLASS B PARTNERSHIP PREFERRED UNITS
 
     On August 4, 1997, in connection with AIMCO's issuance of 750,000 shares of
Class B Preferred Stock, the AIMCO Operating Partnership issued 750,000 Class B
Partnership Preferred Units (the "Class B Partnership Preferred Units") to the
Special Limited Partner. The terms of the Class B Partnership Preferred Units
are substantially the same as the terms of the Class B Preferred Stock. The
Class B Partnership Preferred Units entitle the Special Limited Partner to
receive preferred quarterly cash distributions of $1.78125 per unit or, if
greater, the distributions then payable on Common OP Units into which such Class
B Partnership Preferred Units are convertible. On or after August 4, 1998, upon
the conversion of Class B Preferred Stock into Class A Common Stock, a number of
Class B Partnership Preferred Units equal to the number of shares of Class B
Preferred Stock so converted will be converted into Common OP Units. The number
of Common OP Units issued upon conversion of Class B Partnership Preferred Units
is determined by dividing the Class B Partnership Preferred Unit's liquidation
preference of $100 per unit by $30.45. In addition, each Class B Partnership
Preferred Unit has a priority in liquidation equal to $100 per unit plus an
amount equal to the accumulated, accrued and unpaid dividends on a share of
Class B Preferred Stock.
 
CLASS C PARTNERSHIP PREFERRED UNITS
 
     On December 23, 1997, in connection with AIMCO's issuance of 2,400,000
shares of Class C Preferred Stock, the AIMCO Operating Partnership issued
2,400,000 Class C Partnership Preferred Units (the "Class C Partnership
Preferred Units") to the Special Limited Partner. The terms of the Class C
Partnership Preferred Units are substantially the same as the terms of the Class
C Preferred Stock. The Class C Partnership Preferred Units entitle the Special
Limited Partner to receive preferred quarterly cash distributions of $0.5625 per
unit ($2.25 per annum). In addition, each Class C Partnership Preferred Unit has
a priority in liquidation equal to $25 per unit plus an amount equal to the
accumulated, accrued and unpaid dividends on a share of Class C Preferred Stock.
 
CLASS D PARTNERSHIP PREFERRED UNITS
 
     On February 19, 1998, in connection with AIMCO's issuance of 4,200,000
shares of Class D Preferred Stock, the AIMCO Operating Partnership issued
4,200,000 Class D Partnership Preferred Units (the "Class D Partnership
Preferred Units") to the Special Limited Partner. The terms of the Class D
Partnership
 
                                       56
<PAGE>   169
 
Preferred Units are substantially the same as the terms of the Class D Preferred
Stock. The Class D Partnership Preferred Units entitle the Special Limited
Partner to receive preferred quarterly cash distributions of $0.546875 ($2.1875
per annum). In addition, each Class D Partnership Preferred Unit has a priority
in liquidation equal to $25 per unit plus an amount equal to the accumulated,
accrued and unpaid dividends on a share of Class D Preferred Stock.
 
CLASS E PARTNERSHIP PREFERRED UNITS
 
     If Class E Preferred Stock is issued in connection with the Insignia
Merger, the AIMCO Operating Partnership will concurrently issue an equal number
of Class E Partnership Preferred Units (the "Class E Partnership Preferred
Units") to the Special Limited Partner. The terms of the Class E Partnership
Preferred Units will be substantially the same as the terms of the Class E
Preferred Stock.
 
   
CLASS G PARTNERSHIP PREFERRED UNITS
    
 
   
     On July 15, 1998, in connection with AIMCO's issuance of 4,050,000 shares
of Class G Preferred Stock, the AIMCO Operating Partnership issued 4,050,000
Class G Partnership Preferred Units (the "Class G Partnership Preferred Units")
to the Special Limited Partner. The terms of the Class G Partnership Preferred
Units are substantially the same as the terms of the Class G Preferred Stock.
The Class G Partnership Preferred Units entitle the Special Limited Partner to
receive preferred quarterly cash distributions of $0.5859375 ($2.34375 per
annum). In addition, each Class G Partnership Preferred Unit has a priority in
liquidation equal to $25 per unit plus an amount equal to the accumulated,
accrued and unpaid dividends on a share of Class G Preferred Stock.
    
 
   
CLASS H PARTNERSHIP PREFERRED UNITS
    
 
   
     On August 11, 1998, in connection with AIMCO's issuance of 2,000,000 shares
of Class H Preferred Stock, the AIMCO Operating Partnership issued 2,000,000
Class H Partnership Preferred Units (the "Class H Partnership Preferred Units")
to the Special Limited Partner. The terms of the Class H Partnership Preferred
Units are substantially the same as the terms of the Class H Preferred Stock.
The Class H Partnership Preferred Units entitle the Special Limited Partner to
receive preferred quarterly cash distributions of $0.59375 ($2.375 per annum).
In addition, each Class H Partnership Preferred Unit has a priority in
liquidation equal to $25 per unit plus an amount equal to the accumulated,
accrued and unpaid dividends on a share of Class H Preferred Stock.
    
 
HIGH PERFORMANCE UNITS
 
     In January 1998, the AIMCO Operating Partnership sold an aggregate of
15,000 High Performance Units to a joint venture formed by fourteen of AIMCO's
officers and to three of AIMCO's independent directors, Messrs. Martin, Rhodes
and Smith. Holders of High Performance Units have no rights to receive
distributions or allocations of income or loss, or to redeem their High
Performance Units prior to the Valuation Date that is the earlier of (i) January
1, 2001, or (ii) the date on which a change of control (as defined in the AIMCO
Operating Partnership Agreement) occurs. If, on the Valuation Date, the
cumulative Total Return of the Class A Common Stock during the Measurement
Period exceeds the Minimum Return, then, on and after the Valuation Date,
holders of the 15,000 High Performance Units will be entitled to receive
distributions and allocations of income and loss from the AIMCO Operating
Partnership in the same amounts and at the same times (subject to certain
exceptions upon liquidation of the AIMCO Operating Partnership) as would holders
of a number of Common OP Units equal to the quotient obtained by dividing (i)
the product of (A) 15% of the amount by which the cumulative Total Return of the
Class A Common Stock over the Measurement Period exceeds the greater of 115% of
the peer group index or the Minimum Return, multiplied by (B) the weighted
average market value of AIMCO's equity capitalization (including Class A Common
Stock and Common OP Units) by (ii) the market value of one share of Class A
Common Stock on the Valuation Date. If, on the Valuation Date, the cumulative
Total Return of the Class A Common Stock does not satisfy these criteria, then,
on and after the Valuation Date, holders of the 15,000 High Performance Units
will be entitled to receive distributions and allocations of income and loss
from the
                                       57
<PAGE>   170
 
AIMCO Operating Partnership in the same amounts and at the same times (subject
to certain exceptions upon a liquidation of the AIMCO Operating Partnership) as
would holders of 150 Common OP Units. For purposes of determining the market
value of Class A Common Stock or Common OP Units as of any date, the average
closing price of the Class A Common Stock for the 20 trading days immediately
preceding such date is used. It is expected that the Morgan Stanley REIT Index,
a capitalization-weighted index with dividends reinvested of the most actively
traded REITs, will be used as the peer group index for purposes of the High
Performance Units.
 
     Upon the occurrence of a change of control, any holder of High Performance
Units may, subject to certain restrictions, require the AIMCO Operating
Partnership to redeem all or a portion of the High Performance Units held by
such party in exchange for a cash payment per unit equal to the market value of
a share of Class A Common Stock at the time of redemption. However, in the event
that any High Performance Units are tendered for redemption, the AIMCO Operating
Partnership's obligation to pay the redemption price is subject to the prior
right of AIMCO to acquire such High Performance Units in exchange for an equal
number of shares of Class A Common Stock (subject to certain adjustments).
 
DISTRIBUTIONS
 
   
     Preferred OP Units. Holders of Preferred OP Units to be issued hereunder
will have rights to distribution as set forth in the Prospectus Supplement. With
respect to rights of holders of Class B Partnership Preferred Units, Class C
Partnership Preferred Units, Class D Partnership Preferred Units, Class E
Partnership Preferred Units, Class G Partnership Preferred Units and Class H
Partnership Preferred Units, see "-- Class B Partnership Preferred Units;
- -- Class C Partnership Preferred Units; -- Class D Partnership Preferred Units;
- -- Class E Partnership Preferred Units; -- Class G Partnership Preferred Units;
and -- Class H Partnership Preferred Units."
    
 
     High Performance Units. On and after the Valuation Date, holders of High
Performance Units may be entitled to receive distributions in accordance with
the terms of the High Performance Units. See "-- High Performance Units."
 
   
     Common OP Units. Subject to the rights of holders of any outstanding
Preferred OP Units, the AIMCO Operating Partnership Agreement requires the AIMCO
GP to cause the AIMCO Operating Partnership to distribute quarterly all, or such
portion as the AIMCO GP may in its sole and absolute discretion determine, of
Available Cash (as defined in the AIMCO Operating Partnership Agreement)
generated by the AIMCO Operating Partnership during such quarter to the AIMCO
GP, the Special Limited Partner and the holders of Common OP Units ("Common OP
Unitholders") on the record date established by the AIMCO GP with respect to
such quarter, in accordance with their respective interests in the AIMCO
Operating Partnership on such record date. Holders of any other Preferred OP
Units issued in the future may have priority over the AIMCO GP, the Special
Limited Partner and holders of Common OP Units with respect to distributions of
Available Cash, distributions upon liquidation or other distributions.
    
 
   
     Distributions payable with respect to any interest in the AIMCO Operating
Partnership that was not outstanding during the entire quarterly period in
respect of which any distribution is made will be prorated based on the portion
of the period that such interest was outstanding. The AIMCO GP in its sole and
absolute discretion may distribute to the OP Unitholders Available Cash on a
more frequent basis and provide for an appropriate record date. The AIMCO
Operating Partnership Agreement requires the AIMCO GP to take such reasonable
efforts, as determined by it in its sole and absolute discretion and consistent
with AIMCO's qualification as a REIT, to cause the AIMCO Operating Partnership
to distribute sufficient amounts to enable the AIMCO GP to transfer funds to
AIMCO and enable AIMCO to pay stockholder dividends that will (i) satisfy the
requirements (the "REIT Requirements") for qualifying as a REIT under the Code,
and the Treasury Regulations and (ii) avoid any federal income or excise tax
liability of AIMCO.
    
 
   
     While certain of the debt instruments to which the AIMCO Operating
Partnership is a party, including, but not limited to, the BOA Credit Facility
and the WMF Credit Facility, contain restrictions on the payment of
distributions to Common OP Unitholders of the AIMCO Operating Partnership, the
debt instruments allow the AIMCO Operating Partnership to distribute sufficient
amounts to enable the AIMCO GP to transfer
    
                                       58
<PAGE>   171
 
funds to AIMCO which are then used to pay stockholder dividends thereby allowing
AIMCO to maintain its status as a REIT under the Code.
 
   
     No Common OP Unitholder has any right to demand or receive property other
than cash as provided in the AIMCO Operating Partnership Agreement. The AIMCO GP
may determine, in its sole and absolute discretion, to make a distribution in
kind of assets of the AIMCO Operating Partnership to the Common OP Unitholders
or Preferred OP Unitholders, and such assets will be distributed in such a
fashion as to ensure that the fair market value is distributed and allocated in
accordance with the AIMCO Operating Partnership Agreement.
    
 
   
     Subject to the rights of holders of any outstanding Partnership Preferred
Units, net proceeds from the sale or other disposition of all or substantially
all of the assets of the AIMCO Operating Partnership or a related series of
transactions that, taken together, result in the sale or other disposition of
all or substantially all of the assets of the AIMCO Operating Partnership (a
"Terminating Capital Transaction"), and any other cash received or reductions in
reserves made after commencement of the liquidation of the AIMCO Operating
Partnership, will be distributed to the Common OP Unitholders in accordance with
the AIMCO Operating Partnership Agreement.
    
 
   
     The AIMCO Operating Partnership Agreement prohibits the AIMCO Operating
Partnership and the AIMCO GP, on behalf of the AIMCO Operating Partnership, from
making a distribution to any Common OP Unitholder on account of its interest in
Common OP Units if such distribution would violate Section 17-607 of the
Delaware LP Act or other applicable law.
    
 
ALLOCATIONS OF NET INCOME AND NET LOSS
 
   
     Preferred OP Units. With respect to the Class B Partnership Preferred
Units, the Class C Partnership Preferred Units, the Class D Partnership
Preferred Units, the Class E Partnership Preferred Units (if and when issued),
the Class G Partnership Preferred Units, the Class H Partnership Preferred Units
and any similar class of Preferred OP Unit that may be subsequently issued,
gross income and, if necessary, gain will be allocated to the holders of the
Preferred OP Units for any fiscal year (and, if necessary, subsequent fiscal
years) to the extent that the holders of the Preferred OP Units receive a
distribution on any Preferred Units (other than an amount included in any
redemption of Preferred OP Units).If any Preferred OP Units are redeemed, for
the fiscal year that includes such redemption (and, if necessary, for subsequent
fiscal years) (i) gross income and gain (in such relative proportions as the
AIMCO GP in its discretion will determine) will be allocated to the holders of
such class of Preferred OP Units to the extent that the redemption amounts paid
or payable with respect to the Preferred OP Units so redeemed exceeds the
aggregate capital contributions (net of liabilities assumed or taken subject to
by the AIMCO Operating Partnership) per Preferred OP Unit allocable to the
Preferred OP Units so redeemed and (ii) deductions and losses (in such relative
proportions as the AIMCO GP in its discretion will determine) will be allocated
to the holders of such class of Preferred OP Units to the extent that the
aggregate Capital Contributions (net of liabilities assumed or taken subject to
by the AIMCO Operating Partnership) per Preferred OP Unit allocable to the
Preferred OP Units so redeemed exceeds the redemption amount paid or payable
with respect to the Preferred OP Units so redeemed.
    
 
     High Performance Units. On and after the Valuation Date, holders of High
Performance Units may be allocated income and loss in accordance with the terms
of the High Performance Units. See "-- High Performance Units."
 
   
     Common OP Units. Net Income (as defined in the AIMCO Operating Partnership
Agreement) and Net Loss (as defined in the AIMCO Operating Partnership
Agreement) of the AIMCO Operating Partnership will be determined and allocated
with respect to each fiscal year of the AIMCO Operating Partnership as of the
end of each such year. Except as otherwise provided in the AIMCO Operating
Partnership Agreement, an allocation to a Common OP Unitholder of a share of Net
Income or Net Loss will be treated as an allocation of the same share of each
item of income, gain, loss or deduction that is taken into account in computing
Net Income or Net Loss. Except as otherwise provided in the AIMCO Operating
Partnership Agreement and subject to the terms of any outstanding Partnership
Preferred Units, Net Income
    
                                       59
<PAGE>   172
 
   
and Net Loss will be allocated to the holders of Common OP Units in accordance
with their respective Common OP Units at the end of each fiscal year. The AIMCO
Operating Partnership Agreement contains provisions for special allocations
intended to comply with certain regulatory requirements, including the
requirements of Treasury Regulations Sections 1.704-1(b) and 1.704-2. Except as
otherwise provided in the AIMCO Operating Partnership Agreement and subject to
the terms of any outstanding Partnership Preferred Units, for income tax
purposes under the Code and the Treasury Regulations, each Partnership item of
income, gain, loss and deduction will be allocated among the Common OP
Unitholders in the same manner as its correlative item of "book" income, gain,
loss or deduction is allocated pursuant to the AIMCO Operating Partnership
Agreement.
    
 
WITHHOLDING
 
   
     The AIMCO Operating Partnership is authorized to withhold from or pay on
behalf of or with respect to each OP Unitholder any amount of federal, state,
local or foreign taxes that the AIMCO GP determines that the AIMCO Operating
Partnership is required to withhold or pay with respect to any amount
distributable or allocable to such OP Unitholder pursuant to the AIMCO Operating
Partnership Agreement.
    
 
RETURN OF CAPITAL
 
   
     No Partner ("Partner" means the AIMCO GP or an OP Unitholder, and
"Partners" means the AIMCO GP and the OP Unitholders) is entitled to interest on
its capital contribution or on such Partner's capital account. Except (i)
pursuant to the rights of Redemption (as defined below) set forth in the AIMCO
Operating Partnership Agreement, (ii) as provided by law, or (iii) pursuant to
the terms of any outstanding Preferred OP Units, no Partner has any right to
demand or receive the withdrawal or return of its capital contribution from the
AIMCO Operating Partnership, except to the extent of distributions made pursuant
to the AIMCO Operating Partnership Agreement or upon termination of the AIMCO
Operating Partnership. Except to the extent otherwise expressly provided in the
AIMCO Operating Partnership Agreement and subject to the terms of any
outstanding Preferred OP Units, no OP Unitholder or Assignee will have priority
over any other OP Unitholder or Assignee either as to the return of capital
contributions or as to profits, losses or distributions.
    
 
REDEMPTION RIGHTS
 
   
     Preferred OP Units. Holders of Preferred OP Units to be issued hereunder
will have rights to redemption as set forth in the Prospectus Supplement. With
respect to rights of holders of Class B Partnership Preferred Units, Class C
Partnership Preferred Units, Class D Partnership Preferred Units, Class E
Partnership Preferred Units (if and when issued), Class G Partnership Preferred
Units and Class H Partnership Preferred Units, see "-- Class B Partnership
Preferred Units; -- Class C Partnership Preferred Units; -- Class D Partnership
Preferred Units; -- Class E Partnership Preferred Units; -- Class G Partnership
Preferred Units; and -- Class H Partnership Preferred Units."
    
 
     High Performance Units. In the event of a change of control, holders of
High Performance Units will have the same redemption rights as holders of Common
OP Units. See "-- High Performance Units."
 
   
     Common OP Units. After the first anniversary of becoming a holder of Common
OP Units, each Common OP Unitholder and certain Assignees have the right,
subject to the terms and conditions set forth in the AIMCO Operating Partnership
Agreement, to require the AIMCO Operating Partnership to redeem all or a portion
of the Common OP Units held by such party in exchange for a cash amount based on
the value of shares of Class A Common Stock (a "Redemption"). The AIMCO
Operating Partnership's obligation to effect a Redemption, however, will not
arise or be binding against the AIMCO Operating Partnership until and unless
AIMCO declines or fails to exercise its right to purchase such Common OP Units
pursuant to the AIMCO Operating Partnership Agreement.
    
 
   
     On or before the close of business on the fifth business day after a Common
OP Unitholder gives the AIMCO GP a notice of Redemption, the AIMCO GP may, in
its sole and absolute discretion but subject to the restrictions on the
ownership of Class A Common Stock imposed under the Charter and the transfer
    
                                       60
<PAGE>   173
 
restrictions and other limitations thereof, elect to cause AIMCO to acquire some
or all of the tendered Common OP Units from the tendering party in exchange for
Class A Common Stock, based on an exchange ratio of one share of Class A Common
Stock for each Common OP Unit, subject to adjustment as provided in the AIMCO
Operating Partnership Agreement.
 
PARTNERSHIP RIGHT TO CALL COMMON OP UNITS
 
   
     Notwithstanding any other provision of the AIMCO Operating Partnership
Agreement, on and after the date on which the aggregate percentage interests of
the OP Unitholders, other than the Special Limited Partner, are less than one
percent (1%), the AIMCO Operating Partnership will 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 interest) in
the AIMCO Operating Partnership by treating any OP Unitholder as if such OP
Unitholder had tendered for Redemption pursuant to the AIMCO Operating
Partnership Agreement the amount of Common OP Units specified by the AIMCO GP,
in its sole and absolute discretion, by notice to the OP Unitholder.
    
 
TRANSFERS AND WITHDRAWALS
 
   
     Restrictions on Transfer. The AIMCO Operating Partnership Agreement
restricts the transferability of OP Units. Any transfer or purported transfer of
an OP Unit not made in accordance with the AIMCO Operating Partnership Agreement
will be null and void ab initio. Until the expiration of one year from the date
on which an OP Unitholder acquired OP Units, subject to certain exceptions, such
OP Unitholder may not transfer all or any portion of its OP Units to any
transferee without the consent of the AIMCO GP, which consent may be withheld in
its sole and absolute discretion. After the expiration of one year from the date
on which a OP Unitholder acquired OP Units, such OP Unitholder has the right to
transfer all or any portion of its OP Units to any person, subject to the
satisfaction of certain conditions specified in the AIMCO Operating Partnership
Agreement, including the AIMCO GP's right of first refusal. It is a condition to
any transfer (regardless of whether such transfer is effected before or after
the one year holding period) that the transferee assumes by operation of law or
express agreement all of the obligations of the transferor OP Unitholder under
the AIMCO Operating Partnership Agreement with respect to such OP Units, and no
such transfer (other than pursuant to a statutory merger or consolidation
wherein all obligations and liabilities of the transferor Partner are assumed by
a successor corporation by operation of law) will relieve the transferor Partner
of its obligations under the AIMCO Operating Partnership Agreement without the
approval of the AIMCO GP, in its sole and absolute discretion.
    
 
     In connection with any transfer of OP Units, the AIMCO GP will have the
right to receive an opinion of counsel reasonably satisfactory to it to the
effect that the proposed transfer may be effected without registration under the
Securities Act and will not otherwise violate any federal or state securities
laws or regulations applicable to the AIMCO Operating Partnership or the OP
Units transferred.
 
   
     No transfer by an OP Unitholder of its OP Units (including any Redemption
or any acquisition of OP Units by the AIMCO GP or by the AIMCO Operating
Partnership) may be made to any person if (i) in the opinion of legal counsel

     Substituted OP Unitholders. No OP Unitholder will have the right to
substitute a transferee as an OP Unitholder in its place. A transferee of the
interest of an OP Unitholder may be admitted as a substituted OP Unitholder only
with the consent of the AIMCO GP, which consent may be given or withheld by the
AIMCO GP in its sole and absolute discretion. If the AIMCO GP, in its sole and
absolute discretion, does not consent to the admission of any permitted
transferee as a substituted OP Unitholder, such transferee will be considered an
Assignee for purposes of the AIMCO Operating Partnership Agreement. An Assignee
will be entitled to all the rights of an assignee of a limited partnership
interest under the Delaware LP Act, including the right to receive distributions
from the AIMCO Operating Partnership and the share of Net Income, Net

Losses and other items of income, gain, loss, deduction and credit of the AIMCO
Operating Partnership attributable to the OP Units assigned to such transferee
and the rights to transfer the OP Units provided in the AIMCO Operating
Partnership Agreement, but will not be deemed to be an OP Unitholder for any
other purpose under the AIMCO Operating Partnership Agreement, and will not be
entitled to effect a consent or vote with respect to such OP Units on any matter
presented to the OP Unitholders for approval (such right to consent or vote, to
the extent provided in this Agreement or under the Delaware LP Act, fully
remaining with the transferor OP Unitholder).
    
 
   
     Withdrawals. No OP Unitholder may withdraw from the AIMCO Operating
Partnership other than as a result of a permitted transfer of all of such OP
Unitholder's OP Units in accordance with the AIMCO Operating Partnership
Agreement, with respect to which the transferee becomes a substituted OP
Unitholder, or pursuant to a Redemption (or acquisition by AIMCO) of all of such
OP Unitholder's OP Units.
    
 
   
     Restrictions on AIMCO GP. The AIMCO GP may not transfer any of its general
partner interest or withdraw from the AIMCO Operating Partnership unless (i) the
OP Unitholders consent or (ii) immediately after a merger of the AIMCO GP into
another entity, substantially all of the assets of the surviving entity, other
than the general partnership interest in the AIMCO Operating Partnership held by
the AIMCO GP, are contributed to the AIMCO Operating Partnership as a capital
contribution in exchange for OP Units.
    
 
ISSUANCE OF CAPITAL STOCK BY AIMCO
 
     Pursuant to the AIMCO Operating Partnership Agreement, upon the issuance of
its capital Stock, AIMCO is generally obligated to contribute the cash proceeds
or other consideration received from such issuance to the AIMCO Operating
Partnership in exchange for, in the case of Class A Common Stock, Common OP
Units, or in the case of an issuance of Preferred Stock, Preferred OP Units with
designations, preferences and other rights, terms and provisions that are
substantially the same as the designations, preferences and other rights, terms
and provisions of such Preferred Stock.
 
DILUTION
 
   
     The AIMCO GP has the power, without the consent of the OP Unitholders, to
cause the AIMCO Operating Partnership to issue additional Common OP Units and
Preferred OP Units without the approval of the OP Unitholders. Any such issuance
may dilute the interests of existing OP Unitholders. In addition, the terms of
the Preferred OP Units entitle the Common OP Unitholder to receive preferential
distributions of cash and a priority in liquidation, as well as certain class
voting rights.
    
 
AMENDMENT OF THE AIMCO OPERATING PARTNERSHIP AGREEMENT
 
   
     By the AIMCO GP Without the Consent of the OP Unitholders. The AIMCO GP has
the power, without the consent of the OP Unitholders, to amend the AIMCO
Operating Partnership Agreement as may be required to facilitate or implement
any of the following purposes: (1) to add to the obligations of the AIMCO GP or
surrender any right or power granted to the AIMCO GP or any affiliate of the
AIMCO GP for the benefit of the OP Unitholders; (2) to reflect the admission,
substitution or withdrawal of OP Unitholders or the termination of the AIMCO
Operating Partnership in accordance with the AIMCO Operating Partnership
Agreement; (3) to reflect a change that is of an inconsequential nature and does
not adversely affect the OP Unitholders in any material respect, or to cure any
ambiguity, correct or supplement any provision in the AIMCO Operating
Partnership Agreement not inconsistent with law or with other provisions, or
make other changes with respect to matters arising under the AIMCO Operating
Partnership Agreement that will not be inconsistent with law or with the
provisions of the AIMCO Operating Partnership Agreement; (4) to satisfy any
requirements, conditions or guidelines contained in any order, directive,
opinion, ruling or regulation of a federal or state agency or contained in
federal or state law; (5) to reflect such changes as are reasonably necessary
for AIMCO to maintain its status as a REIT; and (6) to modify the manner in
which capital accounts are computed (but only to the extent set forth in the
definition of "Capital Account" in the AIMCO Operating Partnership Agreement or
contemplated by the Code or the Treasury Regulations).

     With the Consent of the OP Unitholders. With the exception of the
circumstances described above whereby the AIMCO GP may, without the consent of
the OP Unitholders, amend the AIMCO Operating Partnership Agreement, amendments
to the AIMCO Operating Partnership Agreement require the OP Unitholders'
consent. Amendments to the AIMCO Operating Partnership Agreement may be proposed
by the AIMCO GP or by holders of a majority of the outstanding Common OP Units,
excluding the Special Limited Partner (a "Majority in Interest"). Following such
proposal, the AIMCO GP will submit any proposed amendment to the OP Unitholders.
The AIMCO GP will seek the written consent of the OP Unitholders on the proposed
amendment or will call a meeting to vote thereon and to transact any other
business that the AIMCO GP may deem appropriate. For purposes of obtaining a
written consent, the AIMCO GP may require a written response within a reasonable
specified time, but not less than fifteen (15) days, and failure to respond in
such time period shall constitute a consent that is consistent with the AIMCO
GP's recommendation with respect to the proposal, provided, however, that an
action shall become effective at such time as requisite consents are received
even if prior to such specified time.
    
 
PROCEDURES FOR ACTIONS AND CONSENTS OF PARTNERS
 
   
     Meetings of the OP Unitholders may be called by the AIMCO GP and will be
called upon the receipt by the AIMCO GP of a written request by a Majority in
Interest of the OP Unitholders. Notice of any such meeting will be given to all
OP Unitholders not less than seven (7) days nor more than thirty (30) days prior
to the date of such meeting. OP Unitholders may vote in person or by proxy at
such meeting. Each meeting of OP Unitholders will be conducted by the AIMCO GP
or such other person as the AIMCO GP may appoint pursuant to such rules for the
conduct of the meeting as the AIMCO GP or such other person deems appropriate in
its sole and absolute discretion. Any action required or permitted to be taken
at a meeting of the OP Unitholders may be taken without a meeting if a written
consent setting forth the action so taken is signed by OP Unitholders holding a
majority of outstanding Common OP Units (or such other percentage as is
expressly required by the AIMCO Operating Partnership Agreement for the action
in question). Such consent may be in one instrument or in several instruments,
and shall have the same force and effect as a vote of the OP Unitholders holding
a majority of outstanding Common OP Units (or such other percentage as is
expressly required by the AIMCO Operating Partnership Agreement for the action
in question). Such consent shall be filed with the AIMCO GP. An action so taken
shall be deemed to have been taken at a meeting held on the effective date so
certified.
    
 
RECORDS AND ACCOUNTING; FISCAL YEAR
 
     The AIMCO Operating Partnership Agreement requires the AIMCO GP to keep or
cause to be kept at the principal office of the AIMCO Operating Partnership
those records and documents required to be maintained by the Delaware LP Act and
other books and records deemed by the AIMCO GP to be appropriate with respect to
the AIMCO Operating Partnership's business. The books of the AIMCO Operating
Partnership will be maintained, for financial and tax reporting purposes, on an
accrual basis in accordance with generally accepted accounting principles, or on
such other basis as the AIMCO GP determines to be necessary or appropriate. To
the extent permitted by sound accounting practices and principles, the AIMCO
Operating Partnership, the AIMCO GP and AIMCO may operate with integrated or
consolidated accounting records, operations and principles. The fiscal year of
the AIMCO Operating Partnership is the calendar year.

     As soon as practicable, but in no event later than one hundred five (105)
days after the close of each calendar quarter and each Fiscal Year, the AIMCO GP
will cause to be mailed to each OP Unitholder, of record as of the last day of
the calendar quarter or as of the close of the Fiscal Year, as the case may be,
a report containing financial statements of the AIMCO Operating Partnership, or
of AIMCO if such statements are prepared solely on a consolidated basis with
AIMCO, for such calendar quarter or Fiscal Year, as the case may be, presented
in accordance with generally accepted accounting principles, and such other
information as may be required by applicable law or regulation or as the AIMCO
GP determines to be appropriate.

to the AIMCO Operating Partnership's income, gains, deductions, losses and other

tax purposes and will use all reasonable effort to furnish, within ninety (90)
days of the close of each taxable year, the tax information reasonably required
by OP Unitholders for federal and state income tax reporting purposes. The OP

     Dissolution. The AIMCO Operating Partnership will dissolve, and its affairs
will be wound up, upon the first to occur of any of the following (each a
"Liquidating Event") (i) December 31, 2093; (ii) an event of withdrawal, as
defined in the Delaware LP Act (including, without limitation, bankruptcy), of
the sole AIMCO GP unless, within ninety (90) days after the withdrawal, a
"majority in interest" (as such phrase is used in Section 17-801(3) of the
Delaware LP Act) of the remaining OP Unitholders agree in writing, in their sole
and absolute discretion, to continue the business of the AIMCO Operating
Partnership and to the appointment, effective as of the date of withdrawal, of a
successor AIMCO GP; (iii) an election to dissolve the AIMCO Operating

     Winding Up. Upon the occurrence of a Liquidating Event, the AIMCO Operating
Partnership will continue solely for the purposes of winding up its affairs in
an orderly manner, liquidating its assets and satisfying the claims of its
creditors and OP Unitholders. The AIMCO GP (or, in the event that there is no
remaining AIMCO GP or the AIMCO GP has dissolved, become bankrupt within the
meaning of the Delaware LP Act or ceased to operate, any person elected by a
Majority in Interest of the OP Unitholders) will be responsible for overseeing
the winding up and dissolution of the AIMCO Operating Partnership and will take
full account of the AIMCO Operating Partnership's liabilities and property, and
the AIMCO Operating Partnership's property will be liquidated as promptly as is
consistent with obtaining the fair value thereof, and the proceeds therefrom
(which may, to the extent determined by the AIMCO GP, include Class A Common
Stock) will be applied and distributed in the following order: (i) first, to the
satisfaction of all of the AIMCO Operating Partnership's debts and liabilities
to creditors other than the OP Unitholders and their Assignees (whether by
payment or the making of reasonable provision for payment thereof); (ii) second,
to the satisfaction of all the AIMCO Operating Partnership's debts and
liabilities to the AIMCO GP (whether by payment or the making of reasonable
provision for payment thereof), including, but not limited to, amounts due as
reimbursements under the AIMCO Operating Partnership Agreement; (ii) third, to
the satisfaction of all of the AIMCO Operating Partnership's debts and
liabilities to the other OP Unitholders and any Assignees (whether by payment or
the making of reasonable provision for payment thereof); (iv) fourth, to the
satisfaction of all liquidation preferences of outstanding Preferred OP Units,
if any, and (v) the balance, if any, to the AIMCO GP, the OP Unitholders and any
Assignees in accordance with and in proportion to their positive capital account
balances, after giving effect to all contributions, distributions and
allocations for all periods.

            COMPARISON OF THE AIMCO OPERATING PARTNERSHIP AND AIMCO
 
   
     Generally, the nature of an investment in the Class A Common Stock is
substantially equivalent economically to an investment in the Common OP Units.
The AIMCO Operating Partnership makes quarterly distributions to holders of
Common OP Units (on a per unit basis) that generally are equal to the dividends
paid on the Class A Common Stock (on a per share basis). However, such
distributions will not necessarily continue to be equal to such dividends.
Common OP Unitholders generally share in the risks and rewards of ownership in
the enterprise being conducted by AIMCO (through the AIMCO Operating
Partnership). However, there are some differences between ownership of Common OP
Units and ownership of Class A Common Stock, some of which may be material to
investors.
    
 
   
     The information below highlights a number of the significant differences
between the AIMCO Operating Partnership and AIMCO relating to, among other
things, form of organization, permitted investments, policies and restrictions,
management structure, compensation and fees, investor rights and federal income
taxation, and compares certain legal rights associated with the ownership of
Common OP Units and Class A Common Stock, respectively. These comparisons are
intended to assist OP Unitholders in understanding how their investment will be
changed if their Common OP Units are exchanged for Class A Common Stock. COMMON
OP UNITHOLDERS SHOULD CAREFULLY REVIEW THE BALANCE OF THIS PROSPECTUS AND THE
REGISTRATION STATEMENT AND THE EXHIBITS THERETO OF WHICH THIS PROSPECTUS IS A
PART AND ANY APPLICABLE PROSPECTUS SUPPLEMENT FOR ADDITIONAL IMPORTANT
INFORMATION ABOUT THE COMPANY.

            FEDERAL INCOME TAXATION OF AIMCO AND AIMCO STOCKHOLDERS
 
     The following is a summary of certain federal income tax consequences
resulting from the acquisition of, holding, exchanging, and otherwise disposing
of Class A Common Stock and the Preferred Stock (collectively, the Class A
Common Stock and the Preferred Stock are referred to herein as the "AIMCO
Stock"). This discussion is based upon the Code, the Treasury Regulations,
rulings issued by the IRS, and judicial decisions, all in effect as of the date
of this Registration Statement and all of which are subject to change, possibly
retroactively. Such summary is also based on the assumptions that the operation
of AIMCO, the AIMCO Operating Partnership and the Subsidiary Partnerships will
be in accordance with their respective organizational documents and partnership
agreements. This summary is for general information only and does not purport to
discuss all aspects of federal income taxation which may be important to a
particular investor in light of its investment or tax circumstances, or to
certain types of investors subject to special tax rules (including financial
institutions, broker-dealers, insurance companies, and, except to the extent
discussed below, tax-exempt organizations and foreign investors, as determined
for United States federal income tax purposes). This summary assumes that
investors will hold their AIMCO Stock as "capital assets" (generally, property
held for investment). No advance ruling has been or will be sought from the IRS
regarding any matter discussed in this Registration Statement.
 
     THE FEDERAL INCOME TAX TREATMENT OF HOLDERS OF AIMCO STOCK DEPENDS IN SOME
INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF
FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE
AVAILABLE. ACCORDINGLY, EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF ACQUIRING,
HOLDING, EXCHANGING, OR OTHERWISE DISPOSING OF AIMCO STOCK AND OF AIMCO'S
ELECTION TO BE SUBJECT TO TAX, FOR FEDERAL INCOME TAX PURPOSES, AS A REAL ESTATE
INVESTMENT TRUST.
 
GENERAL
 
     The REIT provisions of the Code are highly technical and complex. The
following summary sets forth certain aspects of the provisions of the Code that
govern the federal income tax treatment of a REIT and its stockholders. This
summary is qualified in its entirety by the applicable Code provisions, Treasury
Regulations, and administrative and judicial interpretations thereof, all of
which are subject to change, possibly retroactively.
 
   
     AIMCO has elected to be taxed as a REIT under the Code commencing with its
taxable year ending December 31, 1994, and AIMCO intends to continue such
election. Although AIMCO believes, and it has received an opinion of Counsel to
the effect that, commencing with the AIMCO's initial taxable year ended December
31, 1994, AIMCO was organized in conformity with the requirements for
qualification as a REIT, and its proposed method of operation, and its actual
method of operation since its formation, will enable it to meet the requirements
for qualification and taxation as a REIT under the Code. No assurance can be
given that AIMCO has been or will remain so qualified. It must be emphasized
that this opinion is based and conditioned upon certain assumptions and
representations and covenants made by AIMCO as to factual matters (including
representations of AIMCO concerning its business and properties as set forth in
this Registration Statement). The opinion is expressed as of its date and
Counsel has no obligation to advise holders of Securities of any subsequent
change in the matters stated, represented or assumed or any subsequent change in
the applicable law. Moreover, such qualification and taxation as a REIT depends
upon AIMCO's ability to meet, through actual annual operating results,
distribution levels and diversity of stock ownership, the various qualification
tests imposed under the Code as discussed below, the results of which will not
be reviewed by Counsel. Accordingly, no assurance can be given that the actual
results of AIMCO's operation for any one taxable year will satisfy such
requirements. See " -- Failure to Qualify." An opinion of counsel is not binding
on the IRS, and no assurance can be given that the IRS will not challenge
AIMCO's eligibility for taxation as a REIT.
    
 
                                       74
<PAGE>   187
 
   
     Provided AIMCO qualifies for taxation as a REIT, it will generally not be
subject to federal corporate income tax on its net income that is currently
distributed to its stockholders. This treatment substantially eliminates the
"double taxation" (at the corporate and stockholder levels) that generally
results from investment in a corporation. However, notwithstanding AIMCO's
qualification as a REIT, AIMCO will be subject to federal income tax as follows:
First, AIMCO will be taxed at regular corporate rates on any undistributed REIT
taxable income, including undistributed net capital gains. Second, under certain
circumstances, AIMCO may be subject to the "alternative minimum tax" on its
items of tax preference. Third, if AIMCO has net income from prohibited
transactions (which are, in general, certain sales or other dispositions of
property held primarily for sale to customers in the ordinary course of business
other than foreclosure property), such income will be subject to a 100% tax.
Fourth, if AIMCO should fail to satisfy the 75% gross income test or the 95%
gross income test (as discussed below), but has nonetheless maintained its
qualification as a REIT because certain other requirements have been met, it
will be subject to a 100% tax on an amount equal to (a) the gross income
attributable to the greater of the amount by which AIMCO fails the 75% or 95%
test multiplied by (b) a fraction intended to reflect AIMCO's profitability.
Fifth, if AIMCO should fail to distribute during each calendar year at least the
sum of (i) 85% of its REIT ordinary income for such year, (ii) 95% of its REIT
capital gain net income for such year (other than certain long-term capital
gains that AIMCO elects to retain and pay the tax thereon), and (iii) any
undistributed taxable income from prior periods, AIMCO would be subjected to a
4% excise tax on the excess of such required distribution over the amounts
actually distributed. Sixth, if AIMCO acquires assets from a subchapter C
corporation in a transaction in which the adjusted tax basis of the assets in
the hands of AIMCO is determined by reference to the adjusted tax basis of such
assets in the hands of the subchapter C corporation (such as the assets acquired
from Insignia in the Insignia Merger), under Treasury Regulations not yet
promulgated, the subchapter C corporation would be required to recognize any net
Built-In Gain (as defined below) that would have been realized if the Subchapter
C corporation had liquidated on the day before the date of the transfer.
Pursuant to IRS Notice 88-19, AIMCO may elect, in lieu of the treatment
described above, to be subject to tax at the highest regular corporate tax rate
on such gain to the extent of the excess, if any, of the fair market value over
the adjusted basis of such asset as of the beginning of the ten-year period
("Built-in Gain"). AIMCO intends to make such an election and, therefore, will
be taxed at the highest regular corporate rate on such Built-in Gain if, and to
the extent, such assets are sold within the specified ten-year period. It should
be noted that AIMCO has acquired (and will acquire in the Insignia Merger) a
significant amount of assets with Built-in Gain and a taxable disposition by
AIMCO of any of these assets within ten years of their acquisitions would
subject AIMCO to tax under the foregoing rule. Seventh, AIMCO could be subject
to foreign taxes on its investments and activities in foreign jurisdictions. In
addition, AIMCO could also be subject to tax in certain situations and on
certain transactions not presently contemplated.
    
 
  Requirements for Qualification
 
     The Code defines a REIT as a corporation, trust or association (1) that is
managed by one or more trustees or directors; (2) the beneficial ownership of
which is evidenced by transferable shares, or by transferable certificates of
beneficial interest; (3) which would be taxable as a domestic corporation, but
for the special Code provisions applicable to REITs; (4) that is neither a
financial institution nor an insurance company subject to certain provisions of
the Code; (5) the beneficial ownership of which is held by 100 or more persons;
(6) in which, during the last half of each taxable year, not more than 50% in
value of the outstanding stock is owned, directly or indirectly, by five or
fewer individuals (as defined in the Code to include certain entities); and (7)
which meets certain other tests described below (including with respect to the
nature of its income and assets). The Code provides that conditions (1) through
(4) must be met during the entire taxable year, and that condition (5) must be
met during at least 335 days of a taxable year of 12 months, or during a
proportionate part of a taxable year of less than 12 months. The Charter
provides certain restrictions regarding transfers of its shares, which
provisions are intended to assist AIMCO in satisfying the share ownership
requirements described in conditions (5) and (6) above.
 
     To monitor AIMCO's compliance with the share ownership requirements, AIMCO
is required to maintain records regarding the actual ownership of its shares. To
do so, AIMCO must demand written statements each year from the record holders of
certain percentages of its stock in which the record holders are
                                       75
<PAGE>   188
 
to disclose the actual owners of the shares (i.e., the persons required to
include in gross income the REIT dividends). A list of those persons failing or
refusing to comply with this demand must be maintained as part of AIMCO's
records. A stockholder who fails or refuses to comply with the demand must
submit a statement with its tax return disclosing the actual ownership of the
shares and certain other information.
 
     In addition, a corporation may not elect to become a REIT unless its
taxable year is the calendar year. AIMCO satisfies this requirement.
 
  Ownership of Partnership Interests
 
     In the case of a REIT that is a partner in a partnership, Treasury
Regulations provide that the REIT is deemed to own its proportionate share of
the partnership's assets and to earn its proportionate share of the
partnership's income. In addition, the assets and gross income of the
partnership retain the same character in the hands of the REIT for purposes of
the gross income and asset tests applicable to REITs as described below. Thus,
AIMCO's proportionate share of the assets, liabilities and items of income of
the partnerships and limited liability companies in which it has ownership
interests (the "Subsidiary Partnerships") will be treated as assets, liabilities
and items of income of AIMCO for purposes of applying the REIT requirements
described herein. A summary of certain rules governing the federal income
taxation of partnerships and their partners is provided below in "Tax Aspects of
AIMCO's Investments in Partnerships."
 
  Income Tests
 
     In order to maintain qualification as a REIT, AIMCO annually must satisfy
two gross income requirements. First, at least 75% of AIMCO's gross income
(excluding gross income from "prohibited transactions," i.e., certain sales of
property held primarily for sale to customers in the ordinary course of
business) for each taxable year must be derived directly or indirectly from
investments relating to real property or mortgages on real property (including
"rents from real property" and, in certain circumstances, interest) or from
certain types of temporary investments. Second, at least 95% of AIMCO's gross
income (excluding gross income from prohibited transactions) for each taxable
year must be derived from such real property investments, and from dividends,
interest and gain from the sale or disposition of stock or securities (or from
any combination of the foregoing).
 
     Rents received by AIMCO through the Subsidiary Partnerships will qualify as
"rents from real property" in satisfying the gross income requirements described
above, only if several conditions are met, including the following. If rent
attributable to personal property leased in connection with a lease of real
property is greater than 15% of the total rent received under the lease, then
the portion of rent attributable to such personal property will not qualify as
"rents from real property." Moreover, for rents received to qualify as "rents
from real property," the REIT generally must not operate or manage the property
or furnish or render services to the tenants of such property, other than
through an "independent contractor" from which the REIT derives no revenue.
However, AIMCO (or its affiliates) is permitted to directly perform services
that are "usually or customarily rendered" in connection with the rental of
space for occupancy only and are not otherwise considered rendered to the
occupant of the property. In addition, AIMCO (or its affiliates) may provide
non-customary services to tenants of its properties without disqualifying all of
the rent from the property if the payment for such services does not exceed 1%
of the total gross income from the property. For purposes of this test, the
income received from such non-customary services is deemed to be at least 150%
of the direct cost of providing the services.
 
   
     PAMS LP and the other subsidiaries of the Company that manage the Managed
Properties (collectively, the "Management Subsidiaries") receive management fees
and other income. A portion of such fees and other income accrue to AIMCO
through distributions from the Management Subsidiaries that will be classified
as dividend income to the extent of the earnings and profits of the Management
Subsidiaries. Such distributions will generally qualify under the 95% gross
income test but not under the 75% gross income test.
    
 
     If AIMCO fails to satisfy one or both of the 75% or 95% gross income tests
for any taxable year, it may nevertheless qualify as a REIT for such year if it
is entitled to relief under certain provisions of the Code. These relief
provisions will be generally available if AIMCO's failure to meet such tests was
due to reasonable
                                       76
<PAGE>   189
 
cause and not due to willful neglect, AIMCO attaches a schedule of the sources
of its income to its return, and any incorrect information on the schedule was
not due to fraud with intent to evade tax. It is not possible, however, to state
whether in all circumstances AIMCO would be entitled to the benefit of these
relief provisions. If these relief provisions are inapplicable to a particular
set of circumstances involving AIMCO, AIMCO will not qualify as a REIT. As
discussed above in "-- General," even where these relief provisions apply, a tax
is imposed with respect to the excess net income.
 
  Asset Tests
 
     AIMCO, at the close of each quarter of its taxable year, must also satisfy
three tests relating to the nature of its assets. First, at least 75% of the
value of AIMCO's total assets must be represented by real estate assets
(including its allocable share of real estate assets held by the Subsidiary
Partnerships), certain stock or debt instruments purchased by AIMCO with new
capital, cash, cash items and U.S. government securities. Second, not more than
25% of AIMCO's total assets may be represented by securities other than those in
the 75% asset class. Third, of the investments included in the 25% asset class,
the value of any one issuer's securities owned by AIMCO may not exceed 5% of the
value of AIMCO's total assets, and AIMCO may not own more than 10% of any one
issuer's outstanding voting securities.
 
   
     AIMCO indirectly owns interests in the Management Subsidiaries. As set
forth above, the ownership of more than 10% of the voting securities of any one
issuer by a REIT or the investment of more than 5% of the REIT's total assets in
any one issuer's securities is prohibited by the asset tests. AIMCO believes
that its indirect ownership interests in the Management Subsidiaries qualify
under the asset tests set forth above. However, no independent appraisals have
been obtained to support AIMCO's conclusions as to the value of the AIMCO
Operating Partnership's total assets and the value of the AIMCO Operating
Partnership's interest in the Management Subsidiaries and these values are
subject to change in the future. Accordingly, there can be no assurance that the
IRS will not contend that the AIMCO Operating Partnership's ownership interests
in the Management Subsidiaries disqualifies AIMCO from treatment as a REIT.
    
 
   
     AIMCO's indirect interests in the AIMCO Operating Partnership and other
Subsidiary Partnerships are held through wholly owned corporate subsidiaries of
AIMCO organized and operated as "qualified REIT subsidiaries" within the meaning
of the Code. Qualified REIT subsidiaries are not treated as separate entities
from their parent REIT for federal income tax purposes. Instead, all assets,
liabilities and items of income, deduction and credit of each qualified REIT
subsidiary are treated as assets, liabilities and items of AIMCO. Each qualified
REIT subsidiary therefore is not subject to federal corporate income taxation,
although it may be subject to state or local taxation. In addition, AIMCO's
ownership of the voting stock of each qualified REIT subsidiary does not violate
the general restriction against ownership of more than 10% of the voting
securities of any issuer.
    
 
  Annual Distribution Requirements
 
     AIMCO, in order to qualify as a REIT, is required to distribute dividends
(other than capital gain dividends) to its stockholders in an amount at least
equal to (A) the sum of (i) 95% of AIMCO's "REIT taxable income" (computed
without regard to the dividends paid deduction and AIMCO's net capital gain) and
(ii) 95% of the net income (after tax), if any, from foreclosure property, minus
(B) the sum of certain items of noncash income. Such distributions must be paid
in the taxable year to which they relate, or in the following taxable year if
declared before AIMCO timely files its tax return for such year and if paid with
or before the first regular dividend payment after such declaration. To the
extent that AIMCO distributes at least 95%, but less than 100%, of its "REIT
taxable income," as adjusted, it will be subject to tax thereon at ordinary
corporate tax rates. AIMCO may elect to retain, rather than distribute, its net
long-term capital gains and pay tax on such gains. In such a case, AIMCO's
stockholders would include their proportionate share of such undistributed
long-term capital gains in income and receive a credit for their share of the
tax paid by AIMCO. AIMCO's stockholders would then increase the adjusted basis
of their AIMCO shares by the difference between the designated amounts included
in their long-term capital gains and the tax deemed paid with respect to their
shares. If AIMCO should fail to distribute during each calendar year at least
the sum of (i) 85% of its REIT ordinary income for such year and (ii) 95% of its
REIT capital gain net income for such
                                       77
<PAGE>   190
 
   
year (excluding retained long-term capital gains), and (iii) any undistributed
taxable income from prior periods, AIMCO would be subject to a 4% excise tax on
the excess of such required distribution over the amounts actually distributed.
AIMCO believes that it has made, and intends to make, timely distributions
sufficient to satisfy these annual distribution requirements.
    
 
     It is possible that AIMCO, from time to time, may not have sufficient cash
to meet the 95% distribution requirement due to timing differences between (i)
the actual receipt of cash (including receipt of distributions from the AIMCO
Operating Partnership) and (ii) the inclusion of certain items in income by
AIMCO for federal income tax purposes. In the event that such timing differences
occur, in order to meet the 95% distribution requirement, AIMCO may find it
necessary to arrange for short-term, or possibly long-term, borrowings or to pay
dividends in the form of taxable distributions of property.
 
     Under certain circumstances, AIMCO may be able to rectify a failure to meet
the distribution requirement for a year by paying "deficiency dividends" to
stockholders in a later year, which may be included in AIMCO's deduction for
dividends paid for the earlier year. Thus, AIMCO may be able to avoid being
taxed on amounts distributed as deficiency dividends; however, AIMCO will be
required to pay interest and a penalty based on the amount of any deduction
taken for deficiency dividends.
 
   
  Distribution of Acquired Earnings and Profits
    
 
   
     The Code provides that when a REIT acquires a corporation that is currently
a C corporation (i.e., a corporation without a REIT election, such as Insignia),
the REIT may qualify as a REIT only if, as of the close of the year of
acquisition, the REIT has no "earnings and profits" acquired from such C
corporation. In the Insignia Merger, AIMCO will succeed to the earnings and
profits of Insignia and, therefore, AIMCO must distribute such earnings and
profits effective on or before December 31, 1998. Insignia has retained
independent certified public accountants to determine Insignia's earnings and
profits for purposes of this requirement. The determination of the independent
certified public accountants will be based upon Insignia's tax returns as filed
with the IRS and other assumptions and qualifications set forth in the reports
issued by such accountants. Any adjustments to Insignia's income for taxable
years ending on or before the closing of the Insignia Merger, including as a
result of an examination of its returns by the IRS or the receipt of certain
indemnity or other payments, could affect the calculation of Insignia's earnings
and profits. Furthermore, the determination of earnings and profits requires the
resolution of certain technical tax issues with respect to which there is no
authority directly on point and, consequently, the proper treatment of these
issues for earnings and profits purposes is not free from doubt. There can be no
assurance that the IRS will not examine the tax returns of Insignia and propose
adjustments to increase its taxable income and therefore its earnings and
profits. In this regard, the IRS can consider all taxable years of Insignia as
open for review for purposes of determining the amount of such earnings and
profits. Moreover, if the Special Dividend is not treated as a dividend under
the Code, AIMCO may, depending upon the amount of other distributions made by
AIMCO subsequent to the Insignia Merger, fail to distribute an amount equal to
Insignia's earnings and profits. AIMCO's failure to distribute an amount equal
to such earnings and profits effective on or before December 31, 1998, would
result in AIMCO's failure to qualify as a REIT.
    
 
  Failure to Qualify
 
     If AIMCO fails to qualify for taxation as a REIT in any taxable year, and
the relief provisions do not apply, AIMCO will be subject to tax (including any
applicable alternative minimum tax) on its taxable income at regular corporate
rates. Distributions to stockholders in any year in which AIMCO fails to qualify
will not be deductible by AIMCO nor will they be required to be made. In such
event, to the extent of current and accumulated earnings and profits, all
distributions to stockholders will be taxable as ordinary income, and, subject
to certain limitations of the Code, corporate distributees may be eligible for
the dividends received deduction. Unless AIMCO is entitled to relief under
specific statutory provisions, AIMCO would also be disqualified from taxation as
a REIT for the four taxable years following the year during which qualification
was lost. It is not possible to state whether in all circumstances AIMCO would
be entitled to such statutory relief.

TAX ASPECTS OF AIMCO'S INVESTMENTS IN PARTNERSHIPS
 
  General
 
     Substantially all of AIMCO's investments are held indirectly through the
AIMCO Operating Partnership. In general, partnerships are "pass-through"
entities that are not subject to federal income tax. Rather, partners are
allocated their proportionate shares of the items of income, gain, loss,
deduction and credit of a partnership, and are potentially subject to tax
thereon, without regard to whether the partners receive a distribution from the
partnership. AIMCO will include in its income its proportionate share of the
foregoing partnership items for purposes of the various REIT income tests and in
the computation of its REIT taxable income. Moreover, for purposes of the REIT
asset tests, AIMCO will include its proportionate share of assets held by the
Subsidiary Partnerships. See "-- Federal Income Taxation of AIMCO and AIMCO
Stockholders -- General."
 
  Entity Classification
 
   
     AIMCO's direct and indirect investment in partnerships involves special tax
considerations, including the possibility of a challenge by the IRS of the
status of any of the Subsidiary Partnerships as a partnership (as opposed to an
association taxable as a corporation) for federal income tax purposes. If any of
these entities were treated as an association for federal income tax purposes,
it would be subject to an entity-level tax on its income. In such a situation,
the character of AIMCO's assets and items of gross income would change and could
preclude AIMCO from satisfying the asset tests and the income tests (see "--
Federal Income Taxation of AIMCO and AIMCO Stockholders -- Asset Tests" and "--
Federal Income Taxation of AIMCO and AIMCO Stockholders -- Income Tests"), and
in turn could prevent AIMCO from qualifying as a REIT. See "-- Federal Income
Taxation of AIMCO and AIMCO Stockholders -- Failure to Qualify" above for a
discussion of the effect of AIMCO's failure to meet such tests for a taxable
year. In addition, any change in the status of any of the Subsidiary
Partnerships for tax purposes might be treated as a taxable event, in which case
AIMCO might incur a tax liability without any related cash distributions.
    
 
  Tax Allocations with Respect to the Properties
 
   
     Under the Code and the Treasury Regulations, income, gain, loss and
deduction attributable to appreciated or depreciated property that is
contributed to a partnership in exchange for an interest in the partnership must
be allocated in a manner such that the contributing partner is charged with, or
benefits from, respectively, the unrealized gain or unrealized loss associated
with the property at the time of the contribution. The amount of such unrealized
gain or unrealized loss is generally equal to the difference between the fair
market value of the contributed property at the time of contribution, and the
adjusted tax basis of such property at the time of contribution (a "Book -- Tax
Difference"). Such allocations are solely for federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the partners. See "-- Federal Income Taxation of the AIMCO Operating
Partnership and OP Unitholders -- Tax Consequences Upon Contribution of Property
to the AIMCO Operating Partnership." The AIMCO Operating Partnership was formed
by way of contributions of appreciated property (including certain of the Owned
Properties). Consequently, allocations must be made in a manner consistent with
these requirements. Where a partner contributes cash to a partnership that holds
appreciated property, the Treasury Regulations provide for a similar allocation
of such items to the other partners. These rules apply to the contribution by
AIMCO to the AIMCO Operating Partnership of the cash proceeds received in any
offerings of its stock.
    
 
   
     In general, certain OP Unitholders will be allocated lower amounts of
depreciation deductions for tax purposes and increased taxable income and gain
on the sale by the AIMCO Operating Partnership or other Subsidiary Partnerships
of the contributed properties. This will tend to eliminate the Book-Tax
Difference over the life of these partnerships. However, the special allocations
do not always entirely rectify the Book-Tax Difference on an annual basis or
with respect to a specific taxable transaction such as a sale. Thus, the
carryover basis of the contributed properties in the hands of the AIMCO
Operating Partnership or other Subsidiary Partnerships may cause AIMCO to be
allocated lower depreciation and other deductions, and
    
 
                                       79
<PAGE>   192
 
possibly greater amounts of taxable income in the event of a sale of such
contributed assets in excess of the economic or book income allocated to it as a
result of such sale. This may cause AIMCO to recognize taxable income in excess
of cash proceeds, which might adversely affect AIMCO's ability to comply with
the REIT distribution requirements. See "-- Federal Income Taxation of AIMCO and
AIMCO Stockholders -- Annual Distribution Requirements."
 
     With respect to any property purchased or to be purchased by any of the
Subsidiary Partnerships (other than through the issuance of OP Units) subsequent
to the formation of AIMCO, such property will initially have a tax basis equal
to its fair market value and the special allocation provisions described above
will not apply.
 
  Sale of the Properties
 
   
     AIMCO's share of any gain realized by the AIMCO Operating Partnership or
any other Subsidiary Partnership on the sale of any property held as inventory
or primarily for sale to customers in the ordinary course of business will be
treated as income from a prohibited transaction that is subject to a 100%
penalty tax. See "-- Taxation of AIMCO and AIMCO
Stockholders -- General -- Income Tests." Under existing law, whether property
is held as inventory or primarily for sale to customers in the ordinary course
of a partnership's trade or business is a question of fact that depends on all
the facts and circumstances with respect to the particular transaction. The
AIMCO Operating Partnership and the other Subsidiary Partnerships intend to hold
the Owned Properties for investment with a view to long-term appreciation, to
engage in the business of acquiring, developing, owning and operating the Owned
Properties and to make such occasional sales of the Owned Properties, including
peripheral land, as are consistent with AIMCO's investment objectives.
    
 
TAXATION OF MANAGEMENT SUBSIDIARIES
 
   
     A portion of the amounts to be used to fund distributions to stockholders
is expected to come from distributions made by the Management Subsidiaries to
the AIMCO Operating Partnership, and interest paid by the Management
Subsidiaries on certain notes held by the AIMCO Operating Partnership. In
general, the Management Subsidiaries pay federal, state and local income taxes
on their taxable income at normal corporate rates. Any federal, state or local
income taxes that the Management Subsidiaries are required to pay will reduce
AIMCO's cash flow from operating activities and its ability to make payments to
holders of its securities.
    
 
TAXATION OF TAXABLE DOMESTIC STOCKHOLDERS
 
  Distributions
 
   
     Provided AIMCO qualifies as a REIT, distributions made to AIMCO's taxable
domestic stockholders out of current or accumulated earnings and profits (and
not designated as capital gain dividends) will be taken into account by them as
ordinary income and will not be eligible for the dividends received deduction
for corporations. Distributions (and retained long-term capital gains) that are
designated as capital gain dividends will be taxed as long-term capital gains
(to the extent that they do not exceed AIMCO's actual net capital gain for the
taxable year) without regard to the period for which the stockholder has held
its stock. However, corporate stockholders may be required to treat up to 20% of
certain capital gain dividends as ordinary income. In addition, net capital
gains attributable to the sale of depreciable real property held for more than
12 months is subject to a 25% maximum federal income tax rate to the extent of
previously claimed real property depreciation.
    
 
     Distributions in excess of current and accumulated earnings and profits
will not be taxable to a stockholder to the extent that they do not exceed the
adjusted basis of the stockholder's shares in respect of which the distributions
were made, but rather will reduce the adjusted basis of such shares. To the
extent that such distributions exceed the adjusted basis of a stockholder's
shares in respect of which the distributions were made, they will be included in
income as long-term capital gain (or short-term capital gain if the shares have
been held for one year or less) provided that the shares are a capital asset in
the hands of the stockholder. In
 
                                       80
<PAGE>   193
 
   
addition, any dividend declared by AIMCO in October, November or December of any
year and payable to a stockholder of record on a specified date in any such
month will be treated as both paid by AIMCO and received by the stockholder on
December 31 of such year, provided that the dividend is actually paid by AIMCO
during January of the following calendar year. Stockholders may not include in
their individual income tax returns any net operating losses or capital losses
of AIMCO. In general, any loss upon a sale or exchange of shares by a
stockholder who has held such shares for six months or less (after applying
certain holding period rules) will be treated as a long-term capital loss to the
extent of distributions from AIMCO required to be treated by such stockholder as
long-term capital gain.
    
 
  Dispositions of AIMCO Stock
 
     In general, under the recently enacted Internal Revenue Service
Restructuring and Reform Act of 1988, capital gains recognized by individuals
and other non-corporate taxpayers upon the sale or disposition of AIMCO Stock
will be subject to a maximum federal income tax rate of 20% if the AIMCO Stock
is held for more than 12 months and will be taxed at ordinary income rates if
the AIMCO Stock is held for 12 months or less. Capital losses recognized by a
stockholder upon the disposition of AIMCO Stock held for more than one year at
the time of disposition will be a long-term capital loss. In addition, any loss
upon a sale or exchange of shares of AIMCO Stock by a stockholder who has held
such shares for six months or less (after applying certain holding period rules)
will be treated as a long-term capital loss to the extent of distributions from
AIMCO required to be treated by such stockholder as long-term capital gain.
 
     A redemption of the Preferred Stock will be treated under Section 302 of
the Code as a dividend subject to tax at ordinary income tax rates (to the
extent of AIMCO's current or accumulated earnings and profits), unless the
redemption satisfies certain tests set forth in Section 302(b) of the Code
enabling the redemption to be treated as a sale or exchange of the Preferred
Stock. The redemption will satisfy such test if it (i) is "substantially
disproportionate" with respect to the holder (which will not be the case if only
the Preferred Stock is redeemed, since it generally does not have voting
rights), (ii) results in a "complete termination" of the holder's stock interest
in AIMCO, or (iii) is "not essentially equivalent to a dividend" with respect to
the holder, all within the meaning of Section 302(b) of the Code. In determining
whether any of these tests have been met, shares considered to be owned by the
holder by reason of certain constructive ownership rules set forth in the Code,
as well as shares actually owned, must generally be taken into account. Because
the determination as to whether any of the alternative tests of Section 302(b)
of the Code is satisfied with respect to any particular holder of the Preferred
Stock will depend upon the facts and circumstances as of the time the
determination is made, prospective investors are advised to consult their own
tax advisors to determine such tax treatment. If a redemption of the Preferred
Stock is treated as a distribution that is taxable as a dividend, the amount of
the distribution would be measured by the amount of cash and the fair market
value of any property received by the stockholders. The stockholder's adjusted
tax basis in such redeemed Preferred Stock would be transferred to the holder's
remaining stockholdings in AIMCO. If, however, the stockholder has no remaining
stockholdings in AIMCO, such basis may, under certain circumstances, be
transferred to a related person or it may be lost entirely.
 
TAXATION OF FOREIGN STOCKHOLDERS
 
     The following is a discussion of certain anticipated U.S. federal income
and estate tax consequences of the ownership and disposition of AIMCO Stock
applicable to Non-U.S. Holders of AIMCO Stock. A "Non-U.S. Holder" is any person
other than (i) a citizen or resident of the United States, (ii) a corporation or
partnership created or organized in the United States or under the laws of the
United States or of any state thereof or the District of Columbia, (iii) an
estate whose income is includible in gross income for U.S. federal income tax
purposes regardless of its source or (iv) a trust if a United States court is
able to exercise primary supervision over the administration of such trust and
one or more United States fiduciaries have the authority to control all
substantial decisions of such trust. The discussion is based on current law and
is for general information only. The discussion addresses only certain and not
all aspects of U.S. federal income and estate taxation.
 
                                       81
<PAGE>   194
 
  Ordinary Dividends
 
     The portion of dividends received by Non-U.S. Holders payable out of
AIMCO's earnings and profits which are not attributable to capital gains of
AIMCO and which are not effectively connected with a U.S. trade or business of
the Non-U.S. Holder will be subject to U.S. withholding tax at the rate of 30%
(unless reduced by treaty). In general, Non-U.S. Holders will not be considered
engaged in a U.S. trade or business solely as a result of their ownership of
AIMCO Stock. In cases where the dividend income from a Non-U.S. Holder's
investment in AIMCO Stock is (or is treated as) effectively connected with the
Non-U.S. Holder's conduct of a U.S. trade or business, the Non-U.S. Holder
generally will be subject to U.S. tax at graduated rates, in the same manner as
U.S. Holders are taxed with respect to such dividends (and may also be subject
to the 30% branch profits tax in the case of a Non-U.S. Holder that is a
corporation).
 
  Non-Dividend Distributions
 
     Unless AIMCO Stock constitutes a United States Real Property Interest (a
"USRPI"), distributions by AIMCO which are not dividends out of the earnings and
profits of AIMCO will not be subject to U.S. income or withholding tax. If it
cannot be determined at the time a distribution is made whether or not such
distribution will be in excess of current and accumulated earnings and profits,
the distribution will be subject to withholding at the rate applicable to
dividends. However, the Non-U.S. Holder may seek a refund of such amounts from
the IRS if it is subsequently determined that such distribution was, in fact, in
excess of current and accumulated earnings and profits of AIMCO. If AIMCO Stock
constitutes a USRPI, such distributions will be subject to 10% withholding and
taxed pursuant to the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA") at a rate of 35% to the extent such distributions exceed a
stockholder's basis in his or her AIMCO Stock.
 
  Capital Gain Dividends
 
     Under FIRPTA, a distribution made by AIMCO to a Non-U.S. Holder, to the
extent attributable to gains from dispositions of USRPIs such as the properties
beneficially owned by AIMCO ("USRPI Capital Gains"), will be considered
effectively connected with a U.S. trade or business of the Non-U.S. Holder and
subject to U.S. income tax at the rates applicable to U.S. individuals or
corporations, without regard to whether such distribution is designated as a
capital gain dividend. In addition, AIMCO will be required to withhold tax equal
to 35% of the amount of dividends to the extent such dividends constitute USRPI
Capital Gains. Distributions subject to FIRPTA may also be subject to a 30%
branch profits tax in the hands of Non-U.S. Holder that is a corporation.
 
  Dispositions of AIMCO Stock
 
   
     Unless AIMCO Stock constitutes a USRPI, a sale of such stock by a Non-U.S.
Holder generally will not be subject to U.S. taxation under FIRPTA. The stock
will not constitute a USRPI if AIMCO is a "domestically controlled REIT." A
domestically controlled REIT is a REIT in which, at all times during a specified
testing period, less than 50% in value of its shares is held directly or
indirectly by Non-U.S. Holders. AIMCO believes that it is, and it expects to
continue to be, a domestically controlled REIT and, therefore, the sale of AIMCO
Stock should not be subject to taxation under FIRPTA. Because the Class A Common
Stock is publicly traded, however, no assurance can be given that AIMCO is or
will continue to be a domestically controlled REIT.
    
 
   
     If AIMCO does not constitute a domestically controlled REIT, a Non-U.S.
Holder's sale of stock generally will still not be subject to tax under FIRPTA
as a sale of a USRPI provided that (i) the stock is "regularly traded" (as
defined by applicable Treasury Regulations) on an established securities market
(e.g., the NYSE, on which AIMCO Class A Common Stock is listed) and (ii) the
selling Non-U.S. Holder held 5% or less of AIMCO's outstanding stock at all
times during a specified testing period.
    
 
     If gain on the sale of stock of AIMCO were subject to taxation under
FIRPTA, the Non-U.S. Holder would be subject to the same treatment as a U.S.
stockholder with respect to such gain (subject to applicable alternative minimum
tax and a special alternative minimum tax in the case of nonresident alien
individuals)
                                       82
<PAGE>   195
 
and the purchaser of the stock could be required to withhold 10% of the purchase
price and remit such amount to the IRS.
 
   
     Gain from the sale of AIMCO Stock that would not otherwise be subject to
FIRPTA will nonetheless be taxable in the United States to a Non-U.S. Holder in
two cases: (i) if the Non-U.S. Holder's investment in the AIMCO Stock is
effectively connected with a U.S. trade or business conducted by such Non-U.S.
Holder, the Non-U.S. Holder will be subject to the same treatment as a U.S.
stockholder with respect to such gain, or (ii) if the Non-U.S. Holder is a
nonresident alien individual who was present in the United States for 183 days
or more during the taxable year and has a "tax home" in the United States, the
nonresident alien individual will be subject to a 30% tax on the individual's
capital gain.
    
 
  Estate Tax
 
     AIMCO Stock owned or treated as owned by an individual who is not a citizen
or resident (as specially defined for U.S. federal estate tax purposes) of the
United States at the time of death will be includible in the individual's gross
estate for U.S. federal estate tax purposes, unless an applicable estate tax
treaty provides otherwise. Such individual's estate may be subject to U.S.
federal estate tax on the property includible in the estate for U.S. federal
estate tax purposes.
 
INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING
 
     AIMCO will report to its U.S. stockholders and to the IRS the amount of
distributions paid during each calendar year, and the amount of tax withheld, if
any. Under the backup withholding rules, a stockholder may be subject to backup
withholding at the rate of 31% with respect to distributions paid unless such
holder (i) is a corporation or comes within certain other exempt categories and,
when required, demonstrates this fact or (ii) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding, and
otherwise complies with the applicable requirements of the backup withholding
rules. A stockholder who does not provide AIMCO with his correct taxpayer
identification number also may be subject to penalties imposed by the IRS. Any
amount paid as backup withholding will be creditable against the stockholder's
income tax liability. In addition, AIMCO may be required to withhold a portion
of capital gain distributions to any Non-U.S. Holders who fail to certify their
foreign status to AIMCO. The IRS has issued final Treasury Regulations regarding
the backup withholding rules as applied to Non-U.S. Holders. Those final
Treasury Regulations alter the current system of backup withholding compliance
and will be effective for payments made after December 31, 1999. Prospective
investors in AIMCO Stock should consult their tax advisors regarding the
application of these Treasury Regulations.
 
TAXATION OF TAX-EXEMPT STOCKHOLDERS
 
     Tax-exempt entities, including qualified employee pension and profit
sharing trusts and individual retirement accounts ("Exempt Organizations"),
generally are exempt from federal income taxation. However, they are subject to
taxation on their unrelated business taxable income ("UBTI"). While many
investments in real estate generate UBTI, the IRS has ruled that dividend
distributions from a REIT to an exempt employee pension trust do not constitute
UBTI, provided that the shares of the REIT are not otherwise used in an
unrelated trade or business of the exempt employee pension trust. Based on that
ruling, amounts distributed by AIMCO to Exempt Organizations should generally
not constitute UBTI. However, if an Exempt Organization finances its acquisition
of the AIMCO Stock with debt, a portion of its income from AIMCO will constitute
UBTI pursuant to the "debt-financed property" rules. Furthermore, social clubs,
voluntary employee benefit associations, supplemental unemployment benefit
trusts, and qualified group legal services plans that are exempt from taxation
under paragraphs (7), (9), (17) and (20), respectively, of Section 501(c) of the
Code are subject to different UBTI rules, which generally will require them to
characterize distributions from AIMCO as UBTI. In addition, in certain
circumstances, a pension trust that owns more than 10% of AIMCO's stock is
required to treat a percentage of the dividends from AIMCO as UBTI (the "UBTI
Percentage"). The UBTI Percentage is the gross income derived by AIMCO from an
unrelated trade or business (determined as if AIMCO were a pension trust)
divided by the gross income of AIMCO for the year in which the dividends are
paid. The UBTI rule applies to a pension trust holding more than 10% of
                                       83
<PAGE>   196
 
AIMCO's stock only if (i) the UBTI Percentage is at least 5%, (ii) AIMCO
qualifies as a REIT by reason of the modification of the 5/50 Rule that allows
the beneficiaries of the pension trust to be treated as holding shares of AIMCO
in proportion to their actuarial interest in the pension trust, and (iii) either
(A) one pension trust owns more than 25% of the value of AIMCO's stock or (B) a
group of pension trusts each individually holding more than 10% of the value of
AIMCO's stock collectively owns more that 50% of the value of AIMCO's stock. The
restrictions on ownership and transfer of AIMCO's stock should prevent an Exempt
Organization from owning more than 10% of the value of AIMCO's stock.
 
           FEDERAL INCOME TAXATION OF THE AIMCO OPERATING PARTNERSHIP
   
                               AND OP UNITHOLDERS
    
 
     The following is a summary of certain federal income tax consequences
resulting from the acquisition of, holding, exchanging, and otherwise disposing
of OP Units. This discussion is based upon the Code, the Treasury Regulations,
rulings issued by the IRS, and judicial decisions, all in effect as of the date
of this Registration Statement and all of which are subject to change, possibly
retroactively. Such summary is also based on the assumptions that the operation
of AIMCO, the AIMCO Operating Partnership and the Subsidiary Partnerships will
be in accordance with their respective organizational documents and partnership
agreements. This summary is for general information only and does not purport to
discuss all aspects of federal income taxation which may be important to a
particular investor in light of its investment or tax circumstances, or to
certain types of investors subject to special tax rules (including financial
institutions, broker-dealers, insurance companies, and, except to the extent
discussed below, tax-exempt organizations and foreign investors, as determined
for United States federal income tax purposes). This summary assumes that
investors will hold their OP Units as "capital assets' (generally, property held
for investment). No advance ruling has been or will be sought from the IRS
regarding any matter discussed in this Registration Statement.
 
     THE FEDERAL INCOME TAX TREATMENT OF HOLDERS OF OP UNITS DEPENDS IN SOME
INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF
FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE
AVAILABLE. ACCORDINGLY, EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR
REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF ACQUIRING,
HOLDING, EXCHANGING, OR OTHERWISE DISPOSING OF OP UNITS AND OF AIMCO'S ELECTION
TO BE SUBJECT TO TAX, FOR FEDERAL INCOME TAX PURPOSES, AS A REAL ESTATE
INVESTMENT TRUST.
 
PARTNERSHIP STATUS
 
   
     AIMCO has received an opinion of Counsel to the effect that the AIMCO
Operating Partnership is classified as a partnership for federal income tax
purposes, and not as an association taxable as a corporation. It must be
emphasized that this opinion of Counsel is based on and conditioned upon ceratin
assumptions and representations and on opinions of local counsel with respect to
matters of local law. The opinion is expressed as of its date and Counsel has no
obligation to advise AIMCO of any subsequent change in matters stated,
represented or assumed or any subsequent change in the applicable law. An
opinion of Counsel is not binding on the IRS, and no assurance can be given that
the IRS will not challenge the status of the AIMCO Operating Partnership as a
partnership.
    
 
     Some partnerships are, for federal income tax purposes, characterized not
as a partnership but as an association taxable as a corporation or as a
"publicly traded partnership" taxable as a corporation. A partnership will be
classified as a publicly traded partnership if interests therein are traded on
an "established securities market" or are "readily tradable" on a "secondary
market (or the substantial equivalent thereof)."
 
     The AIMCO Operating Partnership believes and intends to take the position
that the AIMCO Operating Partnership should not be classified as a publicly
traded partnership because (i) the OP Units are not traded
 
                                       84
<PAGE>   197
 
on an established securities market and (ii) the OP Units should not be
considered readily tradable on a secondary market or the substantial equivalent
thereof. The determination of whether interests in a partnership are readily
tradable on a secondary market or the substantial equivalent thereof, however,
depends on various facts and circumstances (including facts that are not within
the control of the AIMCO Operating Partnership). Treasury Regulations generally
effective for taxable years beginning after December 31, 1995 (the "PTP
Regulations") provide limited safe harbors, which, if satisfied, will prevent a
partnership's interests from being treated as readily tradable on a secondary
market or the substantial equivalent thereof. Under a grandfather rule, certain
existing partnerships may rely on safe harbors contained in IRS Notice 88-75
rather than on the safe harbors contained in the PTP Regulations for all taxable
years of the partnership beginning before January 1, 2006. The AIMCO Operating
Partnership believes that it is subject to such grandfather rule and that it
cannot rely on the safe harbors contained in the PTP Regulations. The AIMCO
Operating Partnership may not have satisfied any of the safe harbors in Notice
88-75 in its previous tax years. In addition, because the AIMCO Operating
Partnership's ability to satisfy a safe harbor in Notice 88-75 (or to the extent
applicable, a safe harbor in the PTP Regulations) may involve facts that are not
within its control, it is impossible to predict whether the AIMCO Operating
Partnership will satisfy a safe harbor in future tax years. The safe harbors in
Notice 88-75 are not intended to be substantive rules for the determination of
whether partnership interests are readily tradable on a secondary market or the
substantial equivalent thereof, and consequently, the failure to meet these safe
harbors will not necessarily cause the AIMCO Operating Partnership to be treated
as a publicly traded partnership. No assurance can be given, however, that the
IRS will not assert that partnerships such as the AIMCO Operating Partnership
constitute publicly traded partnerships, or that facts and circumstances will
not develop which could result in the AIMCO Operating Partnership being treated
as a publicly traded partnership.
 
   
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, it would nevertheless not be taxable as a corporation as long as
90% or more of its gross income consists of "qualifying income." In general,
qualifying income includes interest, dividends, real property rents (as defined
by section 856 of the Code) and gain from the sale or disposition of real
property. The AIMCO Operating Partnership believes that more than 90% of its
gross income consists of qualifying income and expects that more than 90% of its
gross income in future tax years will consist of qualifying income. In such
event, even if the AIMCO Operating Partnership were characterized as a publicly
traded partnership, it would not be taxable as a corporation. If the AIMCO
Operating Partnership were characterized as a publicly traded partnership,
however, each OP Unitholder would be subject to special rules under section 469
of the Code. See "Limitations on Deductibility of Losses -- Passive Activity
Loss Limitation." No assurance can be given that the actual results of the AIMCO
Operating Partnership's operations for any one taxable year will enable it to
satisfy the qualifying income exception.
    
 
   
     If the AIMCO Operating Partnership were characterized as an association or
publicly traded partnership taxable as a corporation (because it did not meet
the qualifying income exception discussed above), it would be subject to tax at
the entity level as a regular corporation and OP Unitholders would be subject to
tax in the same manner as stockholders of a corporation. Thus, the AIMCO
Operating Partnership would be subject to federal tax (and possibly state and
local taxes) on its net income, determined without reduction for any
distributions made to the OP Unitholders, at regular federal corporate income
tax rates, thereby reducing the amount of any cash available for distribution to
the OP Unitholders, which reduction could also materially and adversely impact
the liquidity and value of the OP Units. In addition, the AIMCO Operating
Partnership's items of income, gain, loss, deduction and credit would not be
passed through to the OP Unitholders and the OP Unitholders would not be subject
to tax on the income earned by the AIMCO Operating Partnership. Distributions
received by an OP Unitholder from the AIMCO Operating Partnership, however,
would be treated as dividend income for federal income tax purposes, subject to
tax as ordinary income to the extent of current and accumulated earnings and
profits of the AIMCO Operating Partnership, and the excess, if any, as a
nontaxable return of capital to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest (without taking into account
Partnership liabilities), and thereafter as gain from the sale of a capital
asset. Characterization of the AIMCO Operating Partnership as an association or
publicly traded partnership taxable as a corporation would also result in the
termination of AIMCO's status as a REIT for
    
 
                                       85
<PAGE>   198
 
federal income tax purposes which would have a material adverse impact on AIMCO.
See "Federal Income Taxation of AIMCO and AIMCO Stockholders -- Tax Aspects of
AIMCO's Investments in Partnerships."
 
     No assurances can be given that the IRS would not challenge the status of
the AIMCO Operating Partnership as a "partnership" which is not "publicly
traded" for federal income tax purposes or that a court would not reach a result
contrary to such positions. Accordingly, each prospective investor is urged to
consult his tax advisor regarding the classification and treatment of the AIMCO
Operating Partnership as a "partnership" for federal income tax purposes.
 
     The following discussion assumes that the AIMCO Operating Partnership is,
and will continue to be, classified and taxed as a partnership for federal
income tax purposes.
 
   
TAXATION OF OP UNITHOLDERS
    
 
     In general, a partnership is treated as a "pass-through" entity for federal
income tax purposes and is not itself subject to federal income taxation. Each
partner of a partnership, however, is subject to tax on his allocable share of
partnership tax items, including partnership income, gains, losses, deductions,
and credits ("Partnership Tax Items") for each taxable year of the partnership
ending within or with such taxable year of the partner, regardless of whether he
receives any actual distributions from the partnership during the taxable year.
Generally, the characterization of any particular Partnership Tax Item is
determined at the partnership, rather than at the partner level, and the amount
of a partner's allocable share of such item is governed by the terms of the
partnership agreement.
 
   
     No federal income tax will be payable by the AIMCO Operating Partnership.
Instead, each OP Unitholder will be (i) required to include in income his
allocable share of any AIMCO Operating Partnership income or gains and (ii)
entitled to deduct his allocable share of any AIMCO Operating Partnership
deductions or losses, but only to the extent of the OP Unitholder's adjusted tax
basis in his AIMCO Operating Partnership interest and subject to the "at risk"
and "passive activity loss" rules discussed below under the heading "Limitations
on the Deductibility of Losses." An OP Unitholder's allocable share of the AIMCO
Operating Partnership's taxable income may exceed the cash distributions to the
OP Unitholder for any year if the AIMCO Operating Partnership retains its
profits rather than distributing them.
    
 
ALLOCATIONS OF AIMCO OPERATING PARTNERSHIP PROFITS AND LOSSES
 
   
     For federal income tax purposes, an OP Unitholder's allocable share of the
AIMCO Operating Partnership's Partnership Tax Items will be determined by the
AIMCO Operating Partnership Agreement if such allocations either have
"substantial economic effect" or are determined to be in accordance with the OP
Unitholder's interests in the AIMCO Operating Partnership. The manner in which
Partnership Tax Items of the AIMCO Operating Partnership are allocated is
described above under the heading "Description of OP Units--Allocations of Net
Income and Net Loss." If the allocations provided by the AIMCO Operating
Partnership Agreement were successfully challenged by the IRS, the
redetermination of the allocations to a particular OP Unitholder for federal
income tax purposes may be less favorable than the allocation set forth in the
AIMCO Operating Partnership Agreement.
    
 
TAX BASIS OF A PARTNERSHIP INTEREST
 
   
     A partner's adjusted tax basis in his partnership interest is relevant,
among other things, for determining (i) gain or loss upon a taxable disposition
of his partnership interest, (ii) gain upon the receipt of partnership
distributions, and (iii) the limitations imposed on the use of partnership
deductions and losses allocable to such partner. Generally, the adjusted tax
basis of an OP Unitholder's interest in the AIMCO Operating Partnership is equal
to (A) the sum of the adjusted tax basis of the property contributed by the OP
Unitholder to the AIMCO Operating Partnership in exchange for an interest in the
AIMCO Operating Partnership and the amount of cash, if any, contributed by the
OP Unitholder to the AIMCO Operating Partnership, (B) reduced, but not below
zero, by the OP Unitholder's allocable share of AIMCO Operating Partnership
distributions, deductions, and losses, (C) increased by the OP Unitholder's
allocable share of AIMCO Operating Partnership income and gains, and (D)
increased by the OP Unitholder's allocable share of the
    
                                       86
<PAGE>   199
 
   
AIMCO Operating Partnership liabilities and decreased by the OP Unitholder's
liabilities assumed by the AIMCO Operating Partnership.
    
 
CASH DISTRIBUTIONS
 
   
     Cash distributions received from a partnership do not necessarily correlate
with income earned by the partnership as determined for federal income tax
purposes. Thus, an OP Unitholder's federal income tax liability in respect of
his allocable share of the AIMCO Operating Partnership taxable income for a
particular taxable year may exceed the amount of cash, if any, received by the
OP Unitholder from the AIMCO Operating Partnership during such year.
    
 
   
     If cash distributions, including a "deemed" cash distribution as discussed
below, received by an OP Unitholder in any taxable year exceed his allocable
share of the AIMCO Operating Partnership taxable income for the year, the excess
will constitute, for federal income tax purposes, a return of capital to the
extent of such OP Unitholder's adjusted tax basis in his AIMCO Operating
Partnership interest. Such return of capital will not be includible in the
taxable income of the OP Unitholder, for federal income tax purposes, but it
will reduce, but not below zero, the adjusted tax basis of the AIMCO Operating
Partnership interest held by the OP Unitholder. If an OP Unitholder's tax basis
in his AIMCO Operating Partnership interest is reduced to zero, a subsequent
cash distribution received by the OP Unitholder will be subject to tax as
capital gain income, but only if, and to the extent that, such distribution
exceeds the subsequent positive adjustments, if any, to the tax basis of the OP
Unitholder's AIMCO Operating Partnership interest as determined at the end of
the taxable year during which such distribution is received. A decrease in an OP
Unitholder's share of the AIMCO Operating Partnership liabilities resulting from
the payment or other settlement of such liabilities is generally treated, for
federal income tax purposes, as a deemed cash distribution. A decrease in an OP
Unitholder's percentage interest in the AIMCO Operating Partnership, because of
the issuance by the AIMCO Operating Partnership of additional OP Units, or
otherwise, will decrease an OP Unitholder's share of nonrecourse liabilities of
the AIMCO Operating Partnership, if any, and thus, will result in a
corresponding deemed distribution of cash.
    
 
   
     A non-pro rata distribution (or deemed distribution) of money or property
may result in ordinary income to an OP Unitholder, regardless of such OP
Unitholder's tax basis in his OP Units, if the distribution reduces such OP
Unitholder's share of the AIMCO Operating Partnership's "Section 751 Assets."
"Section 751 Assets" are defined by the Code to include "unrealized receivables"
or "substantially appreciated inventory". For this purpose, inventory is
substantially appreciated if its value exceeds 120% of its adjusted basis. Among
other things, "unrealized receivables" include amounts attributable to
previously claimed depreciation deductions on certain types of property. To the
extent that such a reduction in an OP Unitholder's share of Section 751 Assets
occurs, the AIMCO Operating Partnership will be deemed to have distributed a
proportionate share of the Section 751 Assets to the OP Unitholder followed by a
deemed exchange of such assets with the AIMCO Operating Partnership in return
for the non-pro rata portion of the actual distribution made to such OP
Unitholder. This deemed exchange will generally result in the realization of
ordinary income under Section 751(b) by the OP Unitholder. Such income will
equal the excess of (1) the non-pro rata portion of such distribution over (2)
the OP Unitholder's tax basis in such OP Unitholder's share of such Section 751
Assets deemed relinquished in the exchange.
    
 
TAX CONSEQUENCES UPON CONTRIBUTION OF PROPERTY TO THE AIMCO OPERATING
PARTNERSHIP
 
     Generally, Section 721 of the Code provides that neither the Contributing
Partner nor the AIMCO Operating Partnership will recognize a gain or loss, for
federal income tax purposes, upon a contribution of property to the AIMCO
Operating Partnership in exchange for OP Units. Notwithstanding this general
rule of nonrecognition, the Contributing Partner may recognize a gain where the
property transferred is subject to liabilities, or the AIMCO Operating
Partnership assumes liabilities in connection with a transfer of property, and
the amount of such liabilities exceeds the amount of the AIMCO Operating
Partnership liabilities allocated to the Contributing Partner as determined
immediately after the transfer. Such excess is treated by the Contributing
Partner, for federal income tax purposes, as the receipt of a deemed
distribution of cash to the Contributing Partner from the AIMCO Operating
Partnership. If a person transfers to the AIMCO
                                       87
<PAGE>   200
 
   
Operating Partnership an interest in another partnership (the "Underlying
Partnership") in exchange for an OP Unit, the person will be treated, for
federal income tax purposes, as having transferred to the AIMCO Operating
Partnership his allocable share of the liabilities of the Underlying
Partnership, which could result in, or increase the amount of, a deemed cash
distribution. As discussed above, such deemed cash distributions are generally
treated as a nontaxable return of capital to the extent of the Contributing
Partner's adjusted tax basis in his OP Units and thereafter as gain from the
sale of such partnership interest.
    
 
   
     If a Contributing Partner receives or is deemed to receive for federal
income tax purposes, cash in addition to OP Units upon the contribution of
property to the AIMCO Operating Partnership, the transaction will likely be
treated as part contribution of property and part sale of property. In such
event, the Contributing Partner will recognize gain or loss with respect to the
portion of the property that is deemed sold to the AIMCO Operating Partnership.
    
 
   
     If a Contributing Partner transfers property to the AIMCO Operating
Partnership in exchange for an OP Unit and the adjusted tax basis of such
property differs from its fair market value, AIMCO Operating Partnership Tax
Items must be allocated in a manner such that the Contributing Partner is
charged with, or benefits from, respectively, the unrealized gain or unrealized
loss associated with the property at the time of the contribution. Where a
partner contributes cash to a partnership that holds appreciated property, the
Treasury Regulations provide for a similar allocation of such items to the other
partners. These rules may apply to a contribution by AIMCO to the AIMCO
Operating Partnership of cash proceeds received by AIMCO from the offering of
its stock. Such allocations are solely for federal income tax purposes and do
not affect the book capital accounts or other economic or legal arrangements
among the OP Unitholders. The general purpose underlying this provision is to
specially allocate certain Partnership Tax Items in order to place both the
noncontributing and Contributing Partners in the same tax position that they
would have been in had the Contributing Partner contributed property with an
adjusted tax basis equal its fair market value. Treasury Regulations provide the
AIMCO Operating Partnership with several alternative methods and allow the AIMCO
Operating Partnership to adopt any other reasonable method to make allocations
to reduce or eliminate Book-Tax Differences. The AIMCO GP, in its discretion and
in a manner consistent with the Treasury Regulations, will select and adopt a
method of allocating AIMCO Operating Partnership Tax Items, including the
remedial allocation method, for purposes of eliminating such disparities.
    
 
   
     In general, certain OP Unitholders will be allocated lower amounts of
depreciation deductions for tax purposes and increased amounts of taxable income
and gain on the sale by the AIMCO Operating Partnership or other Subsidiary
Partnerships of the contributed properties. Accordingly, in the event the AIMCO
Operating Partnership disposes of contributed property, income attributable to
the Book-Tax Difference of such contributed property generally will be allocated
to the Contributing Partner, and the other OP Unitholders generally will be
allocated only their share of gains attributable to appreciation, if any,
occurring after the contribution of the contributed property. These incremental
allocations of income will not result in additional cash distributions to the
Contributing Partner, with the result that the Contributing Partner may not
necessarily receive cash sufficient to pay the taxes attributable to such
income. These allocations will tend to eliminate the Book-Tax Differences with
respect to the contributed property over the life of the AIMCO Operating
Partnership. However, the special allocation rules of Section 704(c) do not
always entirely rectify the Book-Tax Difference on an annual basis or with
respect to a specific taxable transaction such as a sale. Thus, the carryover
basis of the contributed property in the hands of the AIMCO Operating
Partnership may cause a noncontributing OP Unitholder to be allocated lower
amounts of depreciation and other deductions for tax purposes than would be
allocated to such OP Unitholder if the contributed property had a tax basis
equal to its fair market value at the time of contribution, and possibly to be
allocated taxable gain in the event of a sale of the contributed property in
excess of the economic or book income allocated to it as a result of such sale.
This may cause noncontributing OP Unitholders to recognize taxable income in
excess of cash proceeds.
    
 
LIMITATIONS ON DEDUCTIBILITY OF LOSSES
 
   
     Basis Limitation. To the extent that an OP Unitholder's allocable share of
AIMCO Operating Partnership deductions and losses exceeds his adjusted tax basis
in his AIMCO Operating Partnership interest
    
                                       88
<PAGE>   201
 
   
at the end of the of the taxable year in which the losses and deductions flow
through, the excess losses and deductions cannot be utilized, for federal income
tax purposes, by the OP Unitholder in such year. The excess losses and
deductions may, however, be utilized in the first succeeding taxable year in
which, and to the extent that, there is an increase in the tax basis of the
AIMCO Operating Partnership interest held by such OP Unitholder, but only to the
extent permitted under the "at risk" and "passive activity loss" rules discussed
below.
    
 
   
     "At Risk" Limitation. Under the "at risk" rules of section 465 of the Code,
a noncorporate taxpayer and a closely held corporate taxpayer are generally not
permitted to claim a deduction, for federal income tax purposes, in respect of a
loss from an activity, whether conducted directly by the taxpayer or through an
investment in a partnership, to the extent that the loss exceeds the aggregate
dollar amount which the taxpayer has "at risk" in such activity at the close of
the taxable year. To the extent that losses are not permitted to be used in any
taxable year, such losses may be carried over to subsequent taxable years and
may be claimed as a deduction by the taxpayer if, and to the extent that, the
amount which the taxpayer has "at risk" is increased. Provided certain
requirements are met, the at risk rules generally do not apply to losses arising
from any activity which constitutes "the holding of real property," which the
holding of an OP Unit should constitute.
    
 
   
     "Passive Activity Loss" Limitation. The passive activity loss rules of
section 469 of the Code limit the use of losses derived from passive activities,
which generally includes an investment in limited partnership interests such as
the OP Units. If an investment in an OP Unit is treated as a passive activity,
an OP Unitholder who is an individual investor, as well as certain other types
of investors, would not be able to use losses from the AIMCO Operating
Partnership to offset nonpassive activity income, including salary, business
income, and portfolio income (e.g., dividends, interest, royalties, and gain on
the disposition of portfolio investments) received during the taxable year.
Passive activity losses that are disallowed for a particular taxable year may,
however, be carried forward to offset passive activity income earned by the OP
Unitholder in future taxable years. In addition, such disallowed losses may be
claimed as a deduction, subject to the basis and at risk limitations discussed
above, upon a taxable disposition of an OP Unit by the OP Unitholder, regardless
of whether such OP Unitholder has received any passive activity income during
the year of disposition.
    
 
   
     If the AIMCO Operating Partnership were characterized as a publicly traded
partnership, each OP Unitholder would be required to treat any loss derived from
the AIMCO Operating Partnership separately from any income or loss derived from
any other publicly traded partnership, as well as from income or loss derived
from other passive activities. In such case, any net losses or credits
attributable to the AIMCO Operating Partnership which are carried forward may
only be offset against future income of the AIMCO Operating Partnership.
Moreover, unlike other passive activity losses, suspended losses attributable to
the AIMCO Operating Partnership would only be allowed upon the complete
disposition of the OP Unitholder's "entire interest" in the AIMCO Operating
Partnership (rather than upon the disposition of an interest in an "activity").
    
 
SECTION 754 ELECTION
 
   
     The AIMCO Operating Partnership has made the election permitted by Section
754 of the Code. Election is irrevocable without the consent of the IRS. The
election will generally permit a purchaser of OP Units, such as AIMCO when it
acquires AIMCO OP Units from OP Unitholders, to adjust its share of the basis in
the AIMCO Operating Partnership's properties pursuant to Section 743(b) of the
Code to fair market value (as reflected by the value of consideration paid for
the OP Units), as if such purchaser had acquired a direct interest in the AIMCO
Operating Partnership assets. The Section 743(b) adjustment is attributed solely
to a purchaser of OP Units and is not added to the bases of the AIMCO Operating
Partnership's assets associated with all of the OP Unitholders in the AIMCO
Operating Partnership.
    
 
DEPRECIATION
 
     Section 168(i)(7) of the Code provides that in the case of property
transferred to a partnership in a Section 721 transaction, the transferee shall
be treated as the transferor for purposes of computing the
 
                                       89
<PAGE>   202
 
depreciation deduction with respect to so much of the basis in the hands of the
transferee as does not exceed the adjusted basis in the hands of the transferor.
The effect of this rule would be to continue the historic basis, placed in
service dates and methods with respect to the depreciation of the properties
being contributed by a Contributing Partner to the AIMCO Operating Partnership
in exchange for OP Units. However, an acquiror of OP Units that obtains a
Section 743(b) adjustment by reason of such acquisition (see "Section 754
Election," above) generally will be allowed depreciation with respect to such
adjustment beginning as of the date of the exchange as if it were new property
placed in service as of that date.
 
SALE, REDEMPTION, OR EXCHANGE OF OP UNITS
 
   
     An OP Unitholder will recognize a gain or loss upon a sale of an OP Unit, a
redemption of an OP Unit for cash, an exchange of an OP Unit for shares of AIMCO
Stock, or other taxable disposition of an OP Unit. Gain or loss recognized upon
a sale or exchange of an OP Unit will be equal to the difference between (i) the
sum of the amount realized in the transaction, which, in the case of the receipt
of shares of AIMCO Stock will be an amount equal to their fair market value at
the time that the transaction is consummated, plus the amount of AIMCO Operating
Partnership liabilities allocable to the OP Unit at such time and (ii) the OP
Unitholder's tax basis in the OP Unit disposed of, which tax basis will be
adjusted for the OP Unitholder's allocable share of the AIMCO Operating
Partnership's income or loss for the taxable year of the disposition. In the
case of a gift of an OP Unit, an OP Unitholder will be deemed to have an amount
realized equal to the amount of the AIMCO Operating Partnership's nonrecourse
liabilities allocable to such OP Unit, and to the extent that the amount
realized exceeds the OP Unitholder's basis for the OP Unit disposed of, such OP
Unitholder will recognize gain for federal income tax purposes. The tax
liability resulting from the gain recognized on a disposition of an OP Unit
could exceed the amount of cash and the fair market value of property received.
    
 
   
     If the AIMCO Operating Partnership redeems an OP Unitholder's OP Units for
cash (which is not contributed by AIMCO to effect the redemption), the tax
consequences generally would be the same as described in the preceding
paragraphs, except that if the AIMCO Operating Partnership redeems less than all
of an OP Unitholder's OP Units, the OP Unitholder would recognize no taxable
loss and would recognize taxable gain only to the extent that the cash, plus the
amount of AIMCO Operating Partnership liabilities allocable to the redeemed OP
Units, exceeded the OP Unitholder's adjusted tax basis in all of such OP
Unitholder's OP Units immediately before the redemption.
    
 
   
     Under the recently enacted Internal Revenue Service Restructuring and
Reform Act of 1988, capital gains recognized by individuals and certain other
noncorporate taxpayers upon the sale or disposition of an OP Unit will be
subject to a maximum federal income tax rate of 20% if the OP Unit is held for
more than 12 months and will be taxed at ordinary income tax rates if the OP
Unit is held for 12 months or less. Generally, gain or loss recognized by an OP
Unitholder on the sale or other taxable disposition of an OP Unit will be
taxable as capital gain or loss. However, to the extent that the amount realized
upon the sale or other taxable disposition of an OP Unit attributable to an OP
Unitholder's share of "unrealized receivables" of the AIMCO Operating
Partnership exceeds the basis attributable to those assets, such excess will be
treated as ordinary income. Among other things, "unrealized receivables" include
amounts attributable to previously claimed depreciation deductions on certain
types of property. In addition, the maximum federal income tax rate for net
capital gains attributable to the sale of depreciable real property (which may
be determined to include an interest in a partnership such as the AIMCO
Operating Partnership) held for more than 12 months is currently 25% (rather
than 20%) to the extent of previously claimed depreciation deductions that would
not be treated as "unrealized receivables."
    
 
TERMINATION OF THE AIMCO OPERATING PARTNERSHIP
 
   
     In the event of the dissolution of the AIMCO Operating Partnership, a
distribution of AIMCO Operating Partnership property (other than money and
marketable securities) will not result in taxable gain to an OP Unitholder
(except to the extent provided in Section 737 of the Code for liquidations
occurring within seven years of the date of contribution by an OP Unitholder of
property to the AIMCO Operating Partnership), and the OP Unitholder will hold
such distributed property with a basis equal to the adjusted basis of such OP
Units exchanged therefor, reduced by any money distributed in liquidation.
Further, the liquidation of the
    
                                       90
<PAGE>   203
 
   
AIMCO Operating Partnership will be taxable to a holder of Units to the extent
that the value of any money and marketable securities distributed in liquidation
(including any money deemed distributed as a result of relief from liabilities)
exceeds such OP Unitholder's tax basis in his OP Units.
    
 
ALTERNATIVE MINIMUM TAX
 
   
     The Code contains different sets of minimum tax rules applicable to
corporate and noncorporate investors. The discussion below relates only to the
alternative minimum tax applicable to noncorporate taxpayers. Accordingly,
corporate investors should consult with their tax advisors with respect to the
effect of the corporate minimum tax provisions that may be applicable to them.
Noncorporate taxpayers are subject to an alternative minimum tax to the extent
the tentative minimum tax ("TMT") exceeds the regular income tax otherwise
payable. The rate of tax imposed on the alternative minimum taxable income
("AMTI") in computing TMT is 26% on the first $175,000 of alternative minimum
taxable income in excess of an exemption amount and 28% on any additional
alternative minimum taxable income of noncorporate investors. In general, AMTI
consists of the taxpayer's taxable income, determined with certain adjustments,
plus his items of tax preference. For example, alternative minimum taxable
income is calculated using an alternative cost recovery (depreciation) system
that is not as favorable as the methods provided for under Section 168 of the
Code which the AIMCO Operating Partnership will use in computing its income for
regular federal income tax purposes. Accordingly, an OP Unitholder's AMTI
derived from the AIMCO Operating Partnership may be higher than such OP
Unitholder's share of the AIMCO Operating Partnership's net taxable income.
Prospective investors should consult with their tax advisors as to the impact of
an investment in OP Units on their liability for the alternative minimum tax.
    
 
INFORMATION RETURNS AND AUDIT PROCEDURES
 
   
     The AIMCO Operating Partnership will use all reasonable efforts to furnish
to each OP Unitholder within 90 days after the close of each taxable year of the
AIMCO Operating Partnership, certain tax information, including a Schedule K-1,
which sets forth each OP Unitholder's allocable share of the AIMCO Operating
Partnership's Taxable Items. In preparing this information the AIMCO GP will use
various accounting and reporting conventions to determine the respective OP
Unitholder's allocable share of Partnership Tax Items. There is no assurance
that any such conventions will yield a result which conforms to the requirements
of the Code, the Treasury Regulations or administrative interpretations of the
IRS. The AIMCO GP cannot assure a current or prospective OP Unitholder that the
IRS will not successfully contend in court that such accounting and reporting
conventions are impermissible.
    
 
   
     No assurance can be given that the AIMCO Operating Partnership will not be
audited by the IRS or that tax adjustments will not be made. Further, any
adjustments in the AIMCO Operating Partnership's tax returns will lead to
adjustments in OP Unitholders' tax returns and may lead to audits of their
returns and adjustments of items unrelated to the AIMCO Operating Partnership.
Each OP Unitholder would bear the cost of any expenses incurred in connection
with an examination of such OP Unitholder's personal tax return.
    
 
     Partnerships generally are treated as separate entities for purposes of
federal tax audits, judicial review of administrative adjustments by the IRS and
tax settlement proceedings. The tax treatment of Partnership Tax Items generally
are determined at the partnership level in a unified partnership proceeding
rather than in separate proceedings with the partners. The Code provides for one
partner to be designated as the Tax Matters Partner for these purposes.
 
   
     The Tax Matters Partner is authorized, but not required, to take certain
actions on behalf of the AIMCO Operating Partnership and OP Unitholders and can
extend the statute of limitations for assessment of tax deficiencies against OP
Unitholders with respect to the AIMCO Operating Partnership Tax Items. The Tax
Matters Partner may bind an OP Unitholder with less than a 1% profits interest
in the AIMCO Operating Partnership to a settlement with the IRS, unless such OP
Unitholder elects, by filing a statement with the IRS, not to give such
authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial
review (to which all the OP Unitholders are bound) of a final partnership
administrative adjustment and, if the Tax Matters Partner fails to seek judicial
review, such review may be sought by any OP Unitholder having at least
    
 
                                       91
<PAGE>   204
 
   
a 1% interest in the profits of the AIMCO Operating Partnership or by OP
Unitholders having in the aggregate at least a 5% profits interest. However,
only one action for judicial review will go forward, and each OP Unitholder with
an interest in the outcome may participate.
    
 
   
TAXATION OF FOREIGN OP UNITHOLDERS
    
 
     A Non-U.S. Holder will be considered to be engaged in a United States trade
or business on account of its ownership of an OP Unit. As a result, a Non-U.S.
Holder will be required to file federal tax returns with respect to its
allocable share of the AIMCO Operating Partnerships income which is effectively
connected to its trade or business. A Non-U.S. Holder that is a corporation may
also be subject to United States branch profit tax at a rate of 30%, in addition
to regular federal income tax, on its allocable share of such income. Such a tax
may be reduced or eliminated by an income tax treaty between the United States
and the country with respect to which the Non-U.S. Holder is resident for tax
purposes. Non-U.S. Holders are advised to consult their tax advisors regarding
the effects an investment in the AIMCO Operating Partnership may have on
information return requirements and other United States and non-United States
tax matters, including the tax consequences of an investment in the AIMCO
Operating Partnership for the country or other jurisdiction of which such
Non-U.S. Holder is a citizen or in which such Non-U.S. Holder resides or is
otherwise located.
 
                             OTHER TAX CONSEQUENCES
 
POSSIBLE LEGISLATIVE OR OTHER ACTIONS AFFECTING REITS
 
     The rules dealing with federal income taxation are constantly under review
by persons involved in the legislative process and by the IRS and the U.S.
Treasury Department. Changes to the federal laws and interpretations thereof
could adversely affect an investment in AIMCO or the AIMCO Operating
Partnership. For example, a proposal issued by President Clinton on February 2,
1998, if enacted into law, may adversely affect the ability of AIMCO to expand
the present activities of its Management Subsidiaries. It cannot be predicted
whether, when, in what forms, or with what effective dates, the tax laws
applicable to AIMCO or the AIMCO Operating Partnership, or an investment in
AIMCO or the AIMCO Operating Partnership, will be changed.
 
STATE, LOCAL AND FOREIGN TAXES
 
   
     The AIMCO Operating Partnership, OP Unitholders, AIMCO and AIMCO
stockholders may be subject to state, local or foreign taxation in various
jurisdictions, including those in which it or they transact business, own
property or reside. It should be noted that the AIMCO Operating Partnership owns
properties located in a number of states and local jurisdictions, and the AIMCO
Operating Partnership and OP Unitholders may be required to file income tax
returns in some or all of those jurisdictions. The state, local or foreign tax
treatment of the AIMCO Operating Partnership and OP Unitholders and of AIMCO and
its stockholders may not conform to the federal income tax consequences
discussed above. Consequently, prospective investors should consult their own
tax advisors regarding the application and effect of state, local foreign tax
laws on an investment in the AIMCO Operating Partnership or AIMCO.
    
 
                                 LEGAL MATTERS
 
     Certain matters as to Maryland law and the validity of the Class A Common
Stock and the Preferred Stock will be passed upon for AIMCO by Piper & Marbury
L.L.P., Baltimore, Maryland. Certain matters as to the validity of the OP Units
will be passed upon for the AIMCO Operating Partnership by Skadden, Arps, Slate,

                    SECOND AMENDED AND RESTATED AGREEMENT OF
                 LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P.
 
     THIS SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF AIMCO
PROPERTIES, L.P., dated as of July 29, 1994, is entered into by and among
Apartment Investment and Management Company, a Maryland corporation (the
"Previous General Partner"), AIMCO-GP, Inc., a Delaware corporation (the
"General Partner"), AIMCO-LP, Inc., a Delaware corporation (the "Special Limited
Partner"), and the other Limited Partners (as defined below).
 
     WHEREAS, the General Partner has submitted, and the Limited Partners have
approved, an amendment and restatement of the Agreement of Limited Partnership
of AIMCO Properties, L.P. on the terms set forth herein.
 
     NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:
 
   
                                  ARTICLE XXV
    
 
                                 DEFINED TERMS
 
     The following definitions shall be for all purposes, unless otherwise
clearly indicated to the contrary, applied to the terms used in this Agreement.
 
     "Act" means the Delaware Revised Uniform Limited Partnership Act, as it may
be amended from time to time, and any successor to such statute.
 
     "Actions" has the meaning set forth in Section 7.7 hereof.
 
     "Additional Funds" has the meaning set forth in Section 4.3.A hereof.
 
     "Additional Limited Partner" means a Person who is admitted to the
Partnership as a Limited Partner pursuant to Section 4.2 and Section 12.2 hereof
and who is shown as such on the books and records of the Partnership.
 
     "Adjusted Capital Account Deficit" means, with respect to any Partner, the
deficit balance, if any, in such Partner's Capital Account as of the end of the
relevant Fiscal Year, after giving effect to the following adjustments:
 
          (i) decrease such deficit by any amounts that such Partner is
     obligated to restore pursuant to this Agreement or by operation of law upon
     liquidation of such Partner's Partnership Interest or is deemed to be
     obligated to restore pursuant to the penultimate sentence of each of
     Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5); and
 
          (ii) increase such deficit by the items described in Regulations
     Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6).
 
The foregoing definition of "Adjusted Capital Account Deficit" is intended to
comply with the provisions of Regulations Section 1.704-1(b)(2)(ii)(d) and shall
be interpreted consistently therewith.
 
     "Adjustment Factor" means 1.0; provided, however, that in the event that:
 
          (i) the Previous General Partner (a) declares or pays a dividend on
     its outstanding REIT Shares in REIT Shares or makes a distribution to all
     holders of its outstanding REIT Shares in REIT Shares, (b) splits or
     subdivides its outstanding REIT Shares or (c) effects a reverse stock split
     or otherwise combines its outstanding REIT Shares into a smaller number of
     REIT Shares, the Adjustment Factor shall be adjusted by multiplying the
     Adjustment Factor previously in effect by a fraction, (i) the numerator of
     which shall be the number of REIT Shares issued and outstanding on the
     record date for such dividend, distribution, split, subdivision, reverse
     split or combination (assuming for such purposes
                                       B-1
<PAGE>   222
 
     that such dividend, distribution, split, subdivision, reverse split or
     combination has occurred as of such time) and (ii) the denominator of which
     shall be the actual number of REIT Shares (determined without the above
     assumption) issued and outstanding on the record date for such dividend,
     distribution, split, subdivision, reverse split or combination;
 
          (ii) the Previous General Partner distributes any rights, options or
     warrants to all holders of its REIT Shares to subscribe for or to purchase
     or to otherwise acquire REIT Shares (or other securities or rights
     convertible into, exchangeable for or exercisable for REIT Shares) at a
     price per share less than the Value of a REIT Share on the record date for
     such distribution (each a "Distributed Right"), then the Adjustment Factor
     shall be adjusted by multiplying the Adjustment Factor previously in effect
     by a fraction (a) the numerator of which shall be the number of REIT Shares
     issued and outstanding on the record date plus the maximum number of REIT
     Shares purchasable under such Distributed Rights and (b) the denominator of
     which shall be the number of REIT Shares issued and outstanding on the
     record date plus a fraction (1) the numerator of which is the maximum
     number of REIT Shares purchasable under such Distributed Rights times the
     minimum purchase price per REIT Share under such Distributed Rights and (2)
     the denominator of which is the Value of a REIT Share as of the record
     date; provided, however, that, if any such Distributed Rights expire or
     become no longer exercisable, then the Adjustment Factor shall be adjusted,
     effective retroactive to the date of distribution of the Distributed
     Rights, to reflect a reduced maximum number of REIT Shares or any change in
     the minimum purchase price for the purposes of the above fraction; and
 
          (iii) the Previous General Partner shall, by dividend or otherwise,
     distribute to all holders of its REIT Shares evidences of its indebtedness
     or assets (including securities, but excluding any dividend or distribution
     referred to in subsection (i) above), which evidences of indebtedness or
     assets relate to assets not received by the Previous General Partner, the
     General Partner and/or the Special Limited Partner pursuant to a pro rata
     distribution by the Partnership, then the Adjustment Factor shall be
     adjusted to equal the amount determined by multiplying the Adjustment
     Factor in effect immediately prior to the close of business on the date
     fixed for determination of shareholders entitled to receive such
     distribution by a fraction (i) the numerator shall be such Value of a REIT
     Share on the date fixed for such determination and (ii) the denominator
     shall be the Value of a REIT Share on the dates fixed for such
     determination less the then fair market value (as determined by the General
     Partner, whose determination shall be conclusive) of the portion of the
     evidences of indebtedness or assets so distributed applicable to one REIT
     Share.
 
Any adjustments to the Adjustment Factor shall become effective immediately
after the effective date of such event, retroactive to the record date, if any,
for such event, provided, however, that any Limited Partner may waive, by
written notice to the General Partner, the effect of any adjustment to the
Adjustment Factor applicable to the Partnership Common Units held by such
Limited Partner, and, thereafter, such adjustment will not be effective as to
such Partnership Common Units. For illustrative purposes, examples of
adjustments to the Adjustment Factor are set forth on Exhibit B attached hereto.
 
     "Affiliate" means, with respect to any Person, any Person directly or
indirectly controlling or controlled by or under common control with such
Person. For the purposes of this definition, "control" when used with respect to
any Person means the possession, directly or indirectly, of the power to direct
or cause the direction of the management and policies of such Person, whether
through the ownership of voting securities, by contract or otherwise, and the
terms "controlling" and "controlled" have meanings correlative to the foregoing.
 
     "Agreement" means this Second Amended and Restated Agreement of Limited
Partnership of AIMCO Properties, L.P., as it may be amended, supplemented or
restated from time to time.
 
     "Applicable Percentage" has the meaning set forth in Section 8.6.B hereof.
 
     "Appraisal" means, with respect to any assets, the written opinion of an
independent third party experienced in the valuation of similar assets, selected
by the General Partner in good faith. Such opinion may
 
                                       B-2
<PAGE>   223
 
be in the form of an opinion by such independent third party that the value for
such property or asset as set by the General Partner is fair, from a financial
point of view, to the Partnership.
 
     "Assignee" means a Person to whom one or more Partnership Common Units have
been Transferred in a manner permitted under this Agreement, but who has not
become a Substituted Limited Partner, and who has the rights set forth in

             (4) the excess, if any, of the net cash proceeds from the sale,
        exchange, disposition, financing or refinancing of Partnership property
        for such period over the gain (or loss, as the case may be) recognized

        such period (excluding Terminating Capital Transactions), and
 
             (5) all other cash received (including amounts previously accrued
        as Net Income and amounts of deferred income) or any net amounts
        borrowed by the Partnership for such period that was not included in
        determining Net Income or Net Loss for such period;

        such period that was not received by the Partnership during such period,

        that the General Partner determines are necessary or appropriate in its

classified as a REIT.
 
     Section 3.2  Powers.
 
          A. The Partnership shall be empowered to do any and all acts and

     above shall have been specifically consented to by the Previous General
     Partner and the General Partner in writing.
 
     Section 3.3  Partnership Only for Purposes Specified. The Partnership shall
be a limited partnership only for the purposes specified in Section 3.1 hereof,
and this Agreement shall not be deemed to create a company, venture or
partnership between or among the Partners with respect to any activities
whatsoever other than the activities within the purposes of the Partnership as

                             CAPITAL CONTRIBUTIONS
 
     Section 4.1  Capital Contributions of the Partners. The Partners have
heretofore made Capital Contributions to the Partnership. Each Partner owns
Partnership Units in the amount set forth for such Partner on Exhibit A, as the
same may be amended from time to time by the General Partner to the extent
necessary to reflect accurately sales, exchanges or other Transfers,
redemptions, Capital Contributions, the issuance of additional Partnership
Units, or similar events having an effect on a Partner's ownership of
Partnership Units. Except as provided by law or in Section 4.2, 4.3 or 10.4
hereof, the Partners shall have no obligation or right to make any additional
Capital Contributions or loans to the Partnership.
 
     Section 4.2  Issuances of Additional Partnership Interests.
 
          A. General. The General Partner is hereby authorized to cause the
     Partnership to issue additional Partnership Interests, in the form of
     Partnership Units, for any Partnership purpose, at any time or from time to
     time, to the Partners (including the General Partner and the Special
     Limited Partner) or to other Persons, and to admit such Persons as
     Additional Limited Partners, for such consideration and on such terms and
     conditions as shall be established by the General Partner in its sole and
     absolute discretion, all without the approval of any Limited Partners.
     Without limiting the foregoing, the General Partner is expressly authorized
     to cause the Partnership to issue Partnership Units (i) upon the
     conversion, redemption or exchange of any Debt, Partnership Units or other
     securities issued by the Partnership, (ii) for less than fair market value,
     so long as the General Partner concludes in good faith that such issuance
     is in the best interests of the General Partner and the Partnership, and
     (iii) in connection with any merger of any other Person into the
     Partnership if the applicable merger agreement provides that Persons are to
     receive Partnership Units in exchange for their interests in the Person
     merging into the Partnership. Subject to Delaware law, any additional
     Partnership Interests may be issued in one or more classes, or one or more
     series of any of such classes, with such designations, preferences and
     relative, participating, optional or other special rights, powers and
     duties as shall be determined by the General Partner, in its sole and
     absolute discretion without the approval of any Limited Partner, and set
     forth in a written document thereafter attached to and made an exhibit to
     this Agreement (each, a "Partnership Unit Designation"). Without limiting
     the generality of the foregoing, the General Partner shall have authority
     to specify (a) the allocations of items of Partnership income, gain, loss,
     deduction and credit to each such class or series of Partnership Interests;
     (b) the right of each such class or series of Partnership Interests to
     share in Partnership distributions; (c) the rights of each such class or
     series of Partnership Interests upon dissolution and liquidation of the
     Partnership; (d) the voting rights, if any, of each such class or series of
     Partnership Interests; and (e) the conversion, redemption or exchange
     rights applicable to each such class or series of Partnership Interests.
     Upon the issuance of any additional Partnership Interest, the General
     Partner shall amend Exhibit A as appropriate to reflect such issuance.
 
          B. Issuances to the General Partner or Special Limited Partner. No
     additional Partnership Units shall be issued to the General Partner or the
     Special Limited Partner unless (i) the additional Partnership Units are
     issued to all Partners in proportion to their respective Percentage
     Interests, (ii) (a) the additional Partnership Units are (x) Partnership
     Common Units issued in connection with an issuance of REIT Shares, or (y)
     Partnership Units (other than Partnership Common Units) issued in
     connection with an issuance of Preferred Shares, New Securities or other
     interests in the Previous General Partner (other than REIT Shares), which
     Preferred Shares, New Securities or other interests have designations,
     preferences and other rights, terms and provisions that are substantially
     the same as the designations, preferences and other rights, terms and
     provisions of the additional Partnership Units
                                      B-18
<PAGE>   239
 
     issued to the General Partner or the Special Limited Partner, and (b) the
     General Partner or the Special Limited Partner, as the case may be,
     contributes to the Partnership the cash proceeds or other consideration
     received in connection with the issuance of such REIT Shares, Preferred
     Shares, New Securities or other interests in the Previous General Partner,
     (iii) the additional Partnership Units are issued upon the conversion,
     redemption or exchange of Debt, Partnership Units or other securities
     issued by the Partnership, or (iv) the additional Partnership Units are
     issued pursuant to Section 4.6.
 
          C. No Preemptive Rights. No Person, including, without limitation, any
     Partner or Assignee, shall have any preemptive, preferential, participation
     or similar right or rights to subscribe for or acquire any Partnership
     Interest.
 
     Section 4.3  Additional Funds.
 
          A. General. The General Partner may, at any time and from time to
     time, determine that the Partnership requires additional funds ("Additional
     Funds") for the acquisition or development of additional Properties, for
     the redemption of Partnership Units or for such other purposes as the
     General Partner may determine. Additional Funds may be obtained by the
     Partnership, at the election of the General Partner, in any manner provided
     in, and in accordance with, the terms of this Section 4.3 without the
     approval of any Limited Partners.
 
          B. Additional Capital Contributions. The General Partner, on behalf of
     the Partnership, may obtain any Additional Funds by accepting Capital
     Contributions from any Partners or other Persons and issuing additional
     Partnership Units in consideration therefor.
 
          C. Loans by Third Parties. The General Partner, on behalf of the
     Partnership, may obtain any Additional Funds by causing the Partnership to
     incur Debt to any Person (other than the Previous General Partner, the
     General Partner or the Special Limited Partner) upon such terms as the
     General Partner determines appropriate, including making such Debt
     convertible, redeemable or exchangeable for Partnership Units; provided,
     however, that the Partnership shall not incur any such Debt if (i) a
     breach, violation or default of such Debt would be deemed to occur by
     virtue of the Transfer of any Partnership Interest, or (ii) such Debt is
     recourse to any Partner (unless the Partner otherwise agrees).
 
          D. General Partner Loans. The General Partner, on behalf of the
     Partnership, may obtain any Additional Funds by causing the Partnership to
     incur Debt with the Previous General Partner, the General Partner or the
     Special Limited Partner (each, a "General Partner Loan") if (i) such Debt
     is, to the extent permitted by law, on substantially the same terms and
     conditions (including interest rate, repayment schedule, and conversion,
     redemption, repurchase and exchange rights) as Funding Debt incurred by the
     Previous General Partner, the General Partner or the Special Limited
     Partner, the net proceeds of which are loaned to the Partnership to provide
     such Additional Funds, or (ii) such Debt is on terms and conditions no less
     favorable to the Partnership than would be available to the Partnership
     from any third party; provided, however, that the Partnership shall not
     incur any such Debt if (a) a breach, violation or default of such Debt
     would be deemed to occur by virtue of the Transfer of any Partnership
     Interest, or (b) such Debt is recourse to any Partner (unless the Partner
     otherwise agrees).
 
          E. Issuance of Securities by the Previous General Partner. The
     Previous General Partner shall not issue any additional REIT Shares,
     Preferred Shares, Junior Shares or New Securities unless (i) the Previous
     General Partner contributes the cash proceeds or other consideration
     received from the issuance of such additional REIT Shares, Preferred
     Shares, Junior Shares or New Securities, as the case may be, and from the
     exercise of the rights contained in any such additional New Securities, to
     either or both of the General Partner and the Special Limited Partner, and
     (ii) it or they, as the case may be, contribute such cash proceeds or other
     consideration to the Partnership in exchange for (x) in the case of an
     issuance of REIT Shares, Partnership Common Units, or (y) in the case of an
     issuance of Preferred Shares, Junior Shares or New Securities, Partnership
     Units with designations, preferences and other rights, terms and provisions
     that are substantially the same as the designations, preferences and other
     rights, terms and provisions of such Preferred Shares, Junior Shares or New
     Securities; provided, however, that notwithstanding the foregoing, the
     Previous General Partner may issue REIT Shares,
                                      B-19
<PAGE>   240
 
     Preferred Shares, Junior Shares or New Securities (a) pursuant to Section
     4.4 or Section 8.6.B hereof, (b) pursuant to a dividend or distribution

     or New Securities to all of the holders of REIT Shares, Preferred Shares,
     Junior Shares or New Securities, as the case may be, (c) upon a conversion,
     redemption or exchange of Preferred Shares, (d) upon a conversion of Junior
     Shares into REIT Shares, (e) upon a conversion, redemption, exchange or
     exercise of New Securities, or (f) in connection with an acquisition of a
     property or other asset to be owned, directly or indirectly, by the
     Previous General Partner if the General Partner determines that such
     acquisition is in the best interests of the Partnership. In the event of
     any issuance of additional REIT Shares, Preferred Shares, Junior Shares or
     New Securities by the Previous General Partner, and the contribution to the
     Partnership, by the General Partner or the Special Limited Partner, of the
     cash proceeds or other consideration received from such issuance, the
     Partnership shall pay the Previous General Partner's expenses associated
     with such issuance, including any underwriting discounts or commissions.
 
     Section 4.4  Stock Option Plans.
 
          A. Options Granted to Company Employees and Independent Directors. If
     at any time or from time to time, in connection with the Previous General
     Partner's Stock Option Plans, a stock option granted to a Company Employee
     or Independent Director is duly exercised:
 
             (1) The Special Limited Partner shall, as soon as practicable after
        such exercise, make a Capital Contribution to the Partnership in an
        amount equal to the exercise price paid to the Previous General Partner
        by such exercising party in connection with the exercise of such stock
        option.
 
             (2) Notwithstanding the amount of the Capital Contribution actually
        made pursuant to Section 4.4.A(1) hereof, the Special Limited Partner
        shall be deemed to have contributed to the Partnership as a Capital
        Contribution, in consideration of an additional Limited Partner Interest
        (expressed in and as additional Partnership Common Units), an amount
        equal to the Value of a REIT Share as of the date of exercise multiplied
        by the number of REIT Shares then being issued in connection with the
        exercise of such stock option.
 
             (3) An equitable Percentage Interest adjustment shall be made in
        which the Special Limited Partner shall be treated as having made a cash
        contribution equal to the amount described in Section 4.4.A(2) hereof.
 
          B. Options Granted to Partnership Employees. If at any time or from
     time to time, in connection with the Previous General Partner's Stock
     Option Plans, a stock option granted to a Partnership Employee is duly
     exercised:
 
             (1) The General Partner shall cause the Previous General Partner to
        sell to the Partnership, and the Partnership shall purchase from the
        Previous General Partner, the number of REIT Shares as to which such
        stock option is being exercised. The purchase price per REIT Share for
        such sale of REIT Shares to the Partnership shall be the Value of a REIT
        Share as of the date of exercise of such stock option.
 
             (2) The Partnership shall sell to the Optionee (or if the Optionee
        is an employee of a Partnership Subsidiary, the Partnership shall sell
        to such Partnership Subsidiary, which in turn shall sell to the
        Optionee), for a cash price per share equal to the Value of a REIT Share
        at the time of the exercise, the number of REIT Shares equal to (a) the
        exercise price paid to the Previous General Partner by the exercising
        party in connection with the exercise of such stock option divided by
        (b) the Value of a REIT Share at the time of such exercise.
 
             (3) The Partnership shall transfer to the Optionee (or if the
        Optionee is an employee of a Partnership Subsidiary, the Partnership
        shall transfer to such Partnership Subsidiary, which in turn shall
        transfer to the Optionee) at no additional cost, as additional
        compensation, the number of REIT Shares equal to the number of REIT
        Shares described in Section 4.4.B(1) hereof less the number of REIT
        Shares described in Section 4.4.B(2) hereof.

             (4) The Special Limited Partner shall, as soon as practicable after
        such exercise, make a Capital Contribution to the Partnership of an
        amount equal to all proceeds received (from whatever source, but
        excluding any payment in respect of payroll taxes or other withholdings)
        by the Previous General Partner, the General Partner or the Special
        Limited Partner in connection with the exercise of such stock option. An
        equitable Percentage Interest adjustment shall be made in which the
        Special Limited Partner shall be treated as having made a cash
        contribution equal to the amount described in Section 4.4.B(1) hereof.
 
          C. Special Valuation Rule. For purposes of this Section 4.4, in
     determining the Value of a REIT Share, only the trading date immediately
     preceding the exercise of the relevant stock option under the Previous
     General Partner's Stock Option Plans shall be considered.
 
          D. Future Stock Incentive Plans. Nothing in this Agreement shall be
     construed or applied to preclude or restrain the Previous General Partner,
     the General Partner or the Special Limited Partner from adopting, modifying
     or terminating stock incentive plans, in addition to the Previous General
     Partner's Stock Option Plans, for the benefit of employees, directors or
     other business associates of the Previous General Partner, the General
     Partner, the Special Limited Partner, the Partnership or any of their
     Affiliates. The Limited Partners acknowledge and agree that, in the event
     that any such plan is adopted, modified or terminated by the Previous
     General Partner, the General Partner or the Special Limited Partner
     amendments to this Section 4.4 may become necessary or advisable and that
     any approval or consent to any such amendments requested by the Previous
     General Partner, the General Partner or the Special Limited Partner shall
     not be unreasonably withheld or delayed.
 
     Section 4.5  No Interest; No Return. No Partner shall be entitled to
interest on its Capital Contribution or on such Partner's Capital Account.
Except as provided herein or by law, no Partner shall have any right to demand
or receive the return of its Capital Contribution from the Partnership.
 
     Section 4.6  Conversion of Junior Shares. If, at any time, any of the
Junior Shares are converted into REIT Shares, in whole or in part, then a number
of Partnership Common Units equal to (i) the number of REIT Shares issued upon
such conversion divided by (ii) the Adjustment Factor then in effect shall be
issued to the General Partner and the Special Limited Partner (and between the
General Partner and the Special Limited Partner in proportion to their ownership
of Partnership Common Units immediately preceding such conversion), and the
Percentage Interests of the General Partner and the Limited Partners (including
the Special Limited Partner) shall be adjusted to reflect such conversion.
 
                                   ARTICLE 5
 
                                 DISTRIBUTIONS
 
     Section 5.1  Requirement and Characterization of Distributions. Subject to
the terms of any Partnership Unit Designation, the General Partner shall cause
the Partnership to distribute quarterly all, or such portion as the General
Partner may in its sole and absolute discretion determine, of Available Cash
generated by the Partnership during such quarter to the Holders of Partnership
Common Units in accordance with their respective Partnership Common Units held
on such Partnership Record Date. Distributions payable with respect to any
Partnership Units that were not outstanding during the entire quarterly period
in respect of which any distribution is made shall be prorated based on the
portion of the period that such units were outstanding. The General Partner in
its sole and absolute discretion may distribute to the Unitholders Available
Cash on a more frequent basis and provide for an appropriate record date. The
General Partner shall take such reasonable efforts, as determined by it in its
sole and absolute discretion and consistent with the Previous General Partner's
qualification as a REIT, to cause the Partnership to distribute sufficient
amounts to enable (i) the General Partner and the Special Limited Partner to
transfer funds to the Previous General Partner and (ii) the Previous General
Partner to pay shareholder dividends that will (a) satisfy the requirements for
qualifying as a REIT under the Code and Regulations (the "REIT Requirements")
and (b) avoid any federal income or excise tax liability of the Previous General
Partner.

     Section 5.2  Distributions in Kind. No right is given to any Unitholder to
demand and receive property other than cash as provided in this Agreement. The
General Partner may determine, in its sole and absolute discretion, to make a
distribution in kind of Partnership assets to the Unitholders, and such assets
shall be distributed in such a fashion as to ensure that the fair market value
is distributed and allocated in accordance with Articles 5, 6 and 10 hereof.
 
     Section 5.3  Amounts Withheld. All amounts withheld pursuant to the Code or
any provisions of any state or local tax law and Section 10.4 hereof with
respect to any allocation, payment or distribution to any Unitholder shall be
treated as amounts paid or distributed to such Unitholder pursuant to Section
5.1 hereof for all purposes under this Agreement.
 
     Section 5.4  Distributions Upon Liquidation. Notwithstanding the other
provisions of this Article 5, net proceeds from a Terminating Capital
Transaction, and any other cash received or reductions in reserves made after
commencement of the liquidation of the Partnership, shall be distributed to the
Unitholders in accordance with Section 13.2 hereof.
 
     Section 5.5  Restricted Distributions. Notwithstanding any provision to the
contrary contained in this Agreement, neither the Partnership nor the General
Partner, on behalf of the Partnership, shall make a distribution to any
Unitholder on account of its Partnership Interest or interest in Partnership
Units if such distribution would violate Section 17-607 of the Act or other
applicable law.
 
                                   ARTICLE 6
 
                                  ALLOCATIONS
 
     Section 6.1  Timing and Amount of Allocations of Net Income and Net
Loss. Net Income and Net Loss of the Partnership shall be determined and
allocated with respect to each Fiscal Year of the Partnership as of the end of
each such year. Except as otherwise provided in this Article 6, and subject to
Section 11.6.C hereof, an allocation to a Unitholder of a share of Net Income or
Net Loss shall be treated as an allocation of the same share of each item of
income, gain, loss or deduction that is taken into account in computing Net
Income or Net Loss.
 
     Section 6.2  General Allocations. Subject to the terms of any Partnership
Unit Designation, except as otherwise provided in this Article 6 and subject to
Section 11.6.C hereof, Net Income and Net Loss shall be allocated to each of the
Holders of Partnership Common Units in accordance with their respective
Partnership Common Units at the end of each Fiscal Year.
 
     Section 6.3  Additional Allocation Provisions. Notwithstanding the
foregoing provisions of this Article 6:
 
          A. Intentionally Omitted.
 
          B. Regulatory Allocations.
 
             (i) Minimum Gain Chargeback. Except as otherwise provided in
        Regulations Section 1.704-2(f), notwithstanding the provisions of
        Section 6.2 hereof, or any other provision of this Article 6, if there
        is a net decrease in Partnership Minimum Gain during any Fiscal Year,
        each Holder of Partnership Common Units shall be specially allocated
        items of Partnership income and gain for such year (and, if necessary,
        subsequent years) in an amount equal to such Holder's share of the net
        decrease in Partnership Minimum Gain, as determined under Regulations
        Section 1.704-2(g). Allocations pursuant to the previous sentence shall
        be made in proportion to the respective amounts required to be allocated
        to each Holder pursuant thereto. The items to be allocated shall be
        determined in accordance with Regulations Sections 1.704-2(f)(6) and
        1.704-2(j)(2). This Section 6.3.B(i) is intended to qualify as a
        "minimum gain chargeback" within the meaning of Regulations Section
        1.704-2(f) and shall be interpreted consistently therewith.
 
             (ii) Partner Minimum Gain Chargeback. Except as otherwise provided
        in Regulations Section 1.704-2(i)(4) or in Section 6.3.B(i) hereof, if
        there is a net decrease in Partner Minimum Gain
                                      B-22
<PAGE>   243
 
        attributable to a Partner Nonrecourse Debt during any Fiscal Year, each
        Holder of Partnership Common Units who has a share of the Partner
        Minimum Gain attributable to such Partner Nonrecourse Debt, determined
        in accordance with Regulations Section 1.704-2(i)(5), shall be specially
        allocated items of Partnership income and gain for such year (and, if
        necessary, subsequent years) in an amount equal to such Holder's share
        of the net decrease in Partner Minimum Gain attributable to such Partner
        Nonrecourse Debt, determined in accordance with Regulations Section
        1.7042(i)(4). Allocations pursuant to the previous sentence shall be
        made in proportion to the respective amounts required to be allocated to
        each General Partner, Limited Partner and other Holder pursuant thereto.
        The items to be so allocated shall be determined in accordance with
        Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section
        6.3.B(ii) is intended to qualify as a "chargeback of partner nonrecourse
        debt minimum gain" within the meaning of Regulations Section 1.704-2(i)
        and shall be interpreted consistently therewith.
 
             (iii) Nonrecourse Deductions and Partner Nonrecourse
        Deductions. Any Nonrecourse Deductions for any Fiscal Year shall be
        specially allocated to the Holders of Partnership Common Units in
        accordance with their Partnership Common Units. Any Partner Nonrecourse
        Deductions for any Fiscal Year shall be specially allocated to the
        Holder(s) who bears the economic risk of loss with respect to the
        Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions
        are attributable, in accordance with Regulations Section 1.704-2(i).
 
             (iv) Qualified Income Offset. If any Holder of Partnership Common
        Units unexpectedly receives an adjustment, allocation or distribution
        described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6),
        items of Partnership income and gain shall be allocated, in accordance
        with Regulations Section 1.704-1(b)(2)(ii)(d), to such Holder in an
        amount and manner sufficient to eliminate, to the extent required by
        such Regulations, the Adjusted Capital Account Deficit of such Holder as
        quickly as possible, provided that an allocation pursuant to this
        Section 6.3.B(iv) shall be made if and only to the extent that such
        Holder would have an Adjusted Capital Account Deficit after all other
        allocations provided in this Article 6 have been tentatively made as if
        this Section 6.3.B(iv) were not in the Agreement. It is intended that
        this Section 6.3.B(iv) qualify and be construed as a "qualified income
        offset" within the meaning of Regulations Section 1.704-1(b)(2)(ii)(d)
        and shall be interpreted consistently therewith.
 
             (v) Gross Income Allocation. In the event that any Holder of
        Partnership Common Units has a deficit Capital Account at the end of any
        Fiscal Year that is in excess of the sum of (1) the amount (if any) that
        such Holder is obligated to restore to the Partnership upon complete
        liquidation of such Holder's Partnership Interest (including, the
        Holder's interest in outstanding Partnership Preferred Units and other
        Partnership Units) and (2) the amount that such Holder is deemed to be
        obligated to restore pursuant to the penultimate sentences of
        Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Holder
        shall be specially allocated items of Partnership income and gain in the
        amount of such excess to eliminate such deficit as quickly as possible,
        provided that an allocation pursuant to this Section 6.3.B(v) shall be
        made if and only to the extent that such Holder would have a deficit
        Capital Account in excess of such sum after all other allocations
        provided in this Article 6 have been tentatively made as if this Section
        6.3.B(v) and Section 6.3.B(iv) hereof were not in the Agreement.
 
             (vi) Limitation on Allocation of Net Loss. To the extent that any
        allocation of Net Loss would cause or increase an Adjusted Capital
        Account Deficit as to any Holder of Partnership Common Units, such
        allocation of Net Loss shall be reallocated among the other Holders of
        Partnership Common Units in accordance with their respective Partnership
        Common Units, subject to the limitations of this Section 6.3.B(vi).
 
             (vii) Section 754 Adjustment. To the extent that an adjustment to
        the adjusted tax basis of any Partnership asset pursuant to Code Section
        734(b) or Code Section 743(b) is required, pursuant to Regulations
        Section 1.704-1(b)(2) (iv)(m)(2) or Regulations Section
        1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital
        Accounts as the
 
                                      B-23
<PAGE>   244
 
        result of a distribution to a Holder of Partnership Common Units in
        complete liquidation of its interest in the Partnership, 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), and such gain or loss shall be
        specially allocated to the Holders in accordance with their Partnership
        Common Units in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(2) applies, or to the Holders to whom such
        distribution was made in the event that Regulations Section
        1.704-1(b)(2)(iv)(m)(4) applies.
 
             (viii) Curative Allocations. The allocations set forth in Sections
        6.3.B(i), (ii), (iii), (iv), (v), (vi) and (vii) hereof (the "Regulatory
        Allocations") are intended to comply with certain regulatory
        requirements, including the requirements of Regulations Sections
        1.704-1(b) and 1.704-2. Notwithstanding the provisions of Section 6.1
        hereof, the Regulatory Allocations shall be taken into account in
        allocating other items of income, gain, loss and deduction among the
        Holders of Partnership Common Units so that to the extent possible
        without violating the requirements giving rise to the Regulatory
        Allocations, the net amount of such allocations of other items and the
        Regulatory Allocations to each Holder of a Partnership Common Unit shall
        be equal to the net amount that would have been allocated to each such
        Holder if the Regulatory Allocations had not occurred.
 
          C. Special Allocations Upon Liquidation. Notwithstanding any provision
     in this Article VI to the contrary, in the event that the Partnership
     disposes of all or substantially all of its assets in a transaction that
     will lead to a liquidation of the Partnership pursuant to Article XIII
     hereof, then any Net Income or Net Loss realized in connection with such
     transaction and thereafter (and, if necessary, constituent items of income,
     gain, loss and deduction) shall be specially allocated among the Partners
     as required so as to cause liquidating distributions pursuant to Section
     13.2.A(4) hereof to be made in the same amounts and proportions as would
     have resulted had such distributions instead been made pursuant to Section
     5.1 hereof.
 
          D. Allocation of Excess Nonrecourse Liabilities. For purposes of
     determining a Holder's proportional share of the "excess nonrecourse
     liabilities" of the Partnership within the meaning of Regulations Section
     1.752-3(a)(3), each Holder's interest in Partnership profits shall be such
     Holder's share of Partnership Common Units.
 
     Section 6.4  Tax Allocations.
 
          A. In General. Except as otherwise provided in this Section 6.4, for
     income tax purposes under the Code and the Regulations each Partnership
     item of income, gain, loss and deduction (collectively, "Tax Items") shall
     be allocated among the Holders of Partnership Common Units in the same
     manner as its correlative item of "book" income, gain, loss or deduction is
     allocated pursuant to Sections 6.2 and 6.3 hereof.
 
          B. Allocations Respecting Section 704(c) Revaluations. Notwithstanding
     Section 6.4.A hereof, Tax Items with respect to Property that is
     contributed to the Partnership with a Gross Asset Value that varies from
     its basis in the hands of the contributing Partner immediately preceding
     the date of contribution shall be allocated among the Holders of
     Partnership Common Units for income tax purposes pursuant to Regulations
     promulgated under Code Section 704(c) so as to take into account such
     variation. The Partnership shall account for such variation under any
     method approved under Code Section 704(c) and the applicable Regulations as
     chosen by the General Partner, including, without limitation, the
     "traditional method" as described in Regulations Section 1.704-3(b). In the
     event that the Gross Asset Value of any partnership asset is adjusted
     pursuant to subsection (b) of the definition of "Gross Asset Value"
     (provided in Article 1 hereof), subsequent allocations of Tax Items with
     respect to such asset shall take account of the variation, if any, between
     the adjusted basis of such asset and its Gross Asset Value in the same
     manner as under Code Section 704(c) and the applicable Regulations.

     Section 7.1  Management.
 
          A. Except as otherwise expressly provided in this Agreement, all
     management powers over the business and affairs of the Partnership are and
     shall be exclusively vested in the General Partner, and no Limited Partner

     power over the business and affairs of the Partnership. The General Partner
     may not be removed by the Partners with or without cause, except with the
     Consent of the General Partner. In addition to the powers now or hereafter
     granted a general partner of a limited partnership under applicable law or
     that are granted to the General Partner under any other provision of this
     Agreement, the General Partner, subject to the other provisions hereof
     including Section 7.3, shall have full power and authority to do all things

        money (including, without limitation, making prepayments on loans and
        borrowing money to permit the Partnership to make distributions to its
        Partners in such amounts as will permit the Previous General Partner (so
        long as the Previous General Partner qualifies as a REIT) to avoid the
        payment of any federal income tax (including, for this purpose, any
        excise tax pursuant to Code Section 4981) and to make distributions to
        its shareholders sufficient to permit the Previous General Partner to
        maintain REIT status or otherwise to satisfy the REIT Requirements), the
        assumption or guarantee of, or other contracting for, indebtedness and
        other liabilities, the issuance of evidences of indebtedness (including
        the securing of same by deed to secure debt, mortgage, deed of trust or
        other lien or encumbrance on the Partnership's assets) and the incurring
        of any obligations that it deems necessary for the conduct of the
        activities of the Partnership;
 
             (2) the making of tax, regulatory and other filings, or rendering
        of periodic or other reports to governmental or other agencies having
        jurisdiction over the business or assets of the Partnership;
 
             (3) the acquisition, sale, transfer, exchange or other disposition
        of any assets of the Partnership (including, but not limited to, the
        exercise or grant of any conversion, option, privilege or subscription
        right or any other right available in connection with any assets at any
        time held by the Partnership) or the merger, consolidation,
        reorganization or other combination of the Partnership with or into
        another entity;
 
             (4) the mortgage, pledge, encumbrance or hypothecation of any
        assets of the Partnership, the use of the assets of the Partnership
        (including, without limitation, cash on hand) for any purpose consistent
        with the terms of this Agreement and on any terms that it sees fit,
        including, without limitation, the financing of the operations and
        activities of the General Partner, the Partnership or any of the
        Partnership's Subsidiaries, the lending of funds to other Persons

        from time to time); provided, however, that, as long as the Previous
        General Partner has determined to continue to qualify as a REIT, the

             (17) the exercise of any of the powers of the General Partner
        enumerated in this Agreement on behalf of any Person in which the
        Partnership does not have an interest, pursuant to contractual or other
        arrangements with such Person;
 
             (18) the making, execution and delivery of any and all deeds,

        indemnities, waivers, releases or legal instruments or agreements in
        writing necessary or appropriate in the judgment of the General Partner
        for the accomplishment of any of the powers of the General Partner
        enumerated in this Agreement;
 
             (19) the issuance of additional Partnership Units, as appropriate
        and in the General Partner's sole and absolute discretion, in connection
        with Capital Contributions by Additional Limited Partners and additional
        Capital Contributions by Partners pursuant to Article 4 hereof; and
 
             (20) an election to dissolve the Partnership pursuant to Section
        13.1.C hereof.
 
          B. Each of the Limited Partners agrees that, except as provided in
     Section 7.3 hereof, the General Partner is authorized to execute, deliver
     and perform the above-mentioned agreements and transactions on behalf of
     the Partnership without any further act, approval or vote of the Partners,
     notwithstanding any other provision of this Agreement (except as provided
     in Section 7.3 hereof), the Act or any applicable law, rule or regulation.
     The execution, delivery or performance by the General Partner or the
     Partnership of any agreement authorized or permitted under this Agreement
     shall not constitute a breach by the General Partner of any duty that the
     General Partner may owe the Partnership or the Limited Partners or any
     other Persons under this Agreement or of any duty stated or implied by law
     or equity.
 
          C. At all times from and after the date hereof, the General Partner
     may cause the Partnership to obtain and maintain (i) casualty, liability
     and other insurance on the Properties of the Partnership and (ii) liability
     insurance for the Indemnitees hereunder.
 
          D. At all times from and after the date hereof, the General Partner
     may cause the Partnership to establish and maintain working capital and
     other reserves in such amounts as the General Partner, in its sole and
     absolute discretion, deems appropriate and reasonable from time to time.
 
          E. In exercising its authority under this Agreement, the General
     Partner may, but shall be under no obligation to, take into account the tax
     consequences to any Partner (including the General Partner) of any action
     taken by it. The General Partner and the Partnership shall not have
     liability to a Limited Partner under any circumstances as a result of an
     income tax liability incurred by such Limited Partner as a result of an
     action (or inaction) by the General Partner pursuant to its authority under
     this Agreement so long as the action or inaction is taken in good faith.
 
     Section 7.2  Certificate of Limited Partnership. To the extent that such
action is determined by the General Partner to be reasonable and necessary or
appropriate, the General Partner shall file amendments to and restatements of
the Certificate and do all the things to maintain the Partnership as a limited
partnership (or a partnership in which the limited partners have limited
liability) under the laws of the State of Delaware and each other state, the
District of Columbia or any other jurisdiction, in which the Partnership may
elect to do business or own property. Subject to the terms of Section 8.5.A(4)
hereof, the General Partner shall not be required, before or after filing, to
deliver or mail a copy of the Certificate or any amendment thereto to any
Limited Partner. The General Partner shall use all reasonable efforts to cause
to be filed such other certificates or documents as may be reasonable and
necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the limited
partners have limited liability to the extent provided by applicable law) in the
State of Delaware and any other state, or the District of Columbia or other
jurisdiction, in which the Partnership may elect to do business or own property.
 
     Section 7.3  Restrictions on General Partner's Authority.
 
          A. The General Partner may not take any action in contravention of
     this Agreement, including, without limitation:

        this Agreement;
 
             (2) possess Partnership property, or assign any rights in specific
        Partnership property, for other than a Partnership purpose except as

             (3) admit a Person as a Partner, except as otherwise provided in
        this Agreement;
 
             (4) perform any act that would subject a Limited Partner to
        liability as a general partner in any jurisdiction or any other
        liability except as provided herein or under the Act; or
 
             (5) enter into any contract, mortgage, loan or other agreement that
        prohibits or restricts, or has the effect of prohibiting or restricting,
        the ability of (a) the General Partner, the Previous General Partner or
        the Partnership from satisfying its obligations under Section 8.6 hereof
        in full or (b) a Limited Partner from exercising its rights under
        Section 8.6 hereof to effect a Redemption in full, except, in either
        case, with the written consent of such Limited Partner affected by the
        prohibition or restriction.
 
          B. The General Partner shall not, without the prior Consent of the
     Limited Partners, undertake, on behalf of the Partnership, any of the
     following actions or enter into any transaction that would have the effect
     of such transactions:
 
             (1) except as provided in Section 7.3.C hereof, amend, modify or
        terminate this Agreement other than to reflect the admission,
        substitution, termination or withdrawal of Partners pursuant to Article
        11 or Article 12 hereof;
 
             (2) make a general assignment for the benefit of creditors or
        appoint or acquiesce in the appointment of a custodian, receiver or
        trustee for all or any part of the assets of the Partnership;
 
             (3) institute any proceeding for bankruptcy on behalf of the
        Partnership; or
 
             (4) subject to the rights of Transfer provided in Sections 11.1.C
        and 11.2 hereof, approve or acquiesce to the Transfer of the Partnership
        Interest of the General Partner, or admit into the Partnership any
        additional or successor General Partners.
 
          C. Notwithstanding Section 7.3.B hereof, the General Partner shall
     have the power, without the Consent of the Limited Partners, to amend this
     Agreement as may be required to facilitate or implement any of the
     following purposes:
 
             (1) to add to the obligations of the General Partner or surrender
        any right or power granted to the General Partner or any Affiliate of
        the General Partner for the benefit of the Limited Partners;
 
             (2) to reflect the admission, substitution or withdrawal of
        Partners or the termination of the Partnership in accordance with this
        Agreement, and to amend Exhibits A and C in connection with such
        admission, substitution or withdrawal;
 
             (3) to reflect a change that is of an inconsequential nature and
        does not adversely affect the Limited Partners in any material respect,
        or to cure any ambiguity, correct or supplement any provision in this
        Agreement not inconsistent with law or with other provisions, or make
        other changes with respect to matters arising under this Agreement that
        will not be inconsistent with law or with the provisions of this
        Agreement;
 
             (4) to satisfy any requirements, conditions or guidelines contained
        in any order, directive, opinion, ruling or regulation of a federal or
        state agency or contained in federal or state law;
 
             (5) (a) to reflect such changes as are reasonably necessary (i) for
        either the General Partner or the Special Limited Partner, as the case
        may be, to maintain its status as a "qualified REIT subsidiary" within
        the meaning of Code Section 856(i)(2) or (ii) for the Previous General
        Partner to maintain its status as a REIT or to satisfy the REIT
        Requirement; (b) to reflect the Transfer of all or any part of a
        Partnership Interest among the Previous General Partner, the General
        Partner, the Special Limited Partner or any other "qualified REIT
        subsidiary" (within the meaning of Code Section 856(i)(2)) with respect
        to the Previous General Partner;
 
             (6) to modify the manner in which Capital Accounts are computed
        (but only to the extent set forth in the definition of "Capital Account"
        or contemplated by the Code or the Regulations); and
 
                                      B-28
<PAGE>   249
 
             (7) the issuance of additional Partnership Interests in accordance
        with Section 4.2.
 
     The General Partner will provide notice to the Limited Partners when any
     action under this Section 7.3.C is taken.
 
          D. Notwithstanding Sections 7.3.B and 7.3.C hereof, this Agreement
     shall not be amended, and no action may be taken by the General Partner,
     without the Consent of each Partner adversely affected, if such amendment
     or action would (i) convert a Limited Partner Interest in the Partnership
     into a General Partner Interest (except as a result of the General Partner
     acquiring such Partnership Interest), (ii) modify the limited liability of
     a Limited Partner, (iii) alter the rights of any Partner to receive the
     distributions to which such Partner is entitled, pursuant to Article 5 or
     Section 13.2.A(4) hereof, or alter the allocations specified in Article 6
     hereof (except, in any case, as permitted pursuant to Sections 4.2 and
     7.3.C hereof), (iv) alter or modify the Redemption rights, Cash Amount or
     REIT Shares Amount as set forth in Sections 8.6 and 11.2 hereof, or amend
     or modify any related definitions, or (v) amend this Section 7.3.D;
     provided, however, that the Consent of each Partner adversely affected
     shall not be required for any amendment or action that affects all Partners
     holding the same class or series of Partnership Units on a uniform or pro
     rata basis. Further, no amendment may alter the restrictions on the General
     Partner's authority set forth elsewhere in this Section 7.3 without the
     Consent specified therein. Any such amendment or action consented to by any
     Partner shall be effective as to that Partner, notwithstanding the absence
     of such consent by any other Partner.
 
     Section 7.4  Reimbursement of the General Partner.
 
          A. The General Partner shall not be compensated for its services as
     general partner of the Partnership except as provided in elsewhere in this
     Agreement (including the provisions of Articles 5 and 6 hereof regarding
     distributions, payments and allocations to which it may be entitled in its
     capacity as the General Partner).
 
          B. Subject to Sections 7.4.C and 15.11 hereof, the Partnership shall
     be liable for, and shall reimburse the General Partner on a monthly basis,
     or such other basis as the General Partner may determine in its sole and
     absolute discretion, for all sums expended in connection with the
     Partnership's business, including, without limitation, (i) expenses
     relating to the ownership of interests in and management and operation of,
     or for the benefit of, the Partnership, (ii) compensation of officers and
     employees, including, without limitation, payments under future
     compensation plans of the General Partner that may provide for stock units,
     or other phantom stock, pursuant to which employees of the General Partner
     will receive payments based upon dividends on or the value of REIT Shares,
     (iii) director fees and expenses and (iv) all costs and expenses of the
     General Partner being a public company, including costs of filings with the
     SEC, reports and other distributions to its shareholders; provided,
     however, that the amount of any reimbursement shall be reduced by any
     interest earned by the General Partner with respect to bank accounts or
     other instruments or accounts held by it on behalf of the Partnership as
     permitted pursuant to Section 7.5 hereof. Such reimbursements shall be in
     addition to any reimbursement of the General Partner as a result of
     indemnification pursuant to Section 7.7 hereof.
 
          C. To the extent practicable, Partnership expenses shall be billed
     directly to and paid by the Partnership and, subject to Section 15.11
     hereof, reimbursements to the General Partner or any of its Affiliates by
     the Partnership pursuant to this Section 7.4 shall be treated as
     "guaranteed payments" within the meaning of Code Section 707(c).
 
     Section 7.5  Outside Activities of the Previous General Partner and the
General Partner. Neither the General Partner nor the Previous General Partner
shall directly or indirectly enter into or conduct any business, other than in
connection with (a) the ownership, acquisition and disposition of Partnership
Interests as General Partner, (b) the management of the business of the
Partnership, (c) the operation of the Previous General Partner as a reporting
company with a class (or classes) of securities registered under the Exchange
Act, (d) the Previous General Partner's operations as a REIT, (e) the offering,
sale, syndication, private placement or public offering of stock, bonds,
securities or other interests, (f) financing or refinancing of any
 
                                      B-29
<PAGE>   250
 
type related to the Partnership or its assets or activities, (g) the General
Partner's qualification as a "qualified REIT subsidiary" (within the meaning of
Code Section 856(i)(2)) and (h) such activities as are incidental thereto.
Nothing contained herein shall be deemed to prohibit the General Partner or the
Previous General Partner from executing guarantees of Partnership debt for which
it would otherwise be liable in its capacity as General Partner. Subject to
Section 7.3.B hereof, the General Partner, the Previous General Partner, the
Special Limited Partner and all "qualified REIT subsidiaries" (within the
meaning of Code Section 856(i)(2)), taken as a group, shall not own any assets
or take title to assets (other than temporarily in connection with an
acquisition prior to contributing such assets to the Partnership) other than
Partnership Interests as the General Partner or Special Limited Partner and
other than such cash and cash equivalents, bank accounts or similar instruments
or accounts as such group deems reasonably necessary, taking into account
Section 7.1.D hereof and the requirements necessary for the Previous General
Partner to qualify as a REIT and for the Previous General Partner, the General
Partner and the Special Limited Partner to carry out their respective
responsibilities contemplated under this Agreement and the Charter.
Notwithstanding the foregoing, if the Previous General Partner or the General
Partner acquires assets in its own name and owns Property other than through the
Partnership, the Partners agree to negotiate in good faith to amend this
Agreement, including, without limitation, the definition of "Adjustment Factor,"
to reflect such activities and the direct ownership of assets by the Previous
General Partner or the General Partner. The General Partner and any Affiliates
of the General Partner may acquire Limited Partner Interests and shall be
entitled to exercise all rights of a Limited Partner relating to such Limited
Partner Interests.
 
     Section 7.6  Contracts with Affiliates.
 
          A. The Partnership may lend or contribute funds or other assets to its
     Subsidiaries or other Persons in which it has an equity investment, and
     such Persons may borrow funds from the Partnership, on terms and conditions
     established in the sole and absolute discretion of the General Partner. The
     foregoing authority shall not create any right or benefit in favor of any
     Subsidiary or any other Person.
 
          B. Except as provided in Section 7.5 hereof and subject to Section 3.1
     hereof, the Partnership may transfer assets to joint ventures, limited
     liability companies, partnerships, corporations, business trusts or other
     business entities in which it is or thereby becomes a participant upon such
     terms and subject to such conditions consistent with this Agreement and
     applicable law as the General Partner, in its sole and absolute discretion,
     believes to be advisable.
 
          C. Except as expressly permitted by this Agreement, neither the
     General Partner nor any of its Affiliates shall sell, transfer or convey
     any property to the Partnership, directly or indirectly, except pursuant to
     transactions that are determined by the General Partner in good faith to be
     fair and reasonable.
 
          D. The General Partner, in its sole and absolute discretion and
     without the approval of the Limited Partners, may propose and adopt on
     behalf of the Partnership employee benefit plans funded by the Partnership
     for the benefit of employees of the General Partner, the Partnership,
     Subsidiaries of the Partnership or any Affiliate of any of them in respect
     of services performed, directly or indirectly, for the benefit of the
     Partnership or any of the Partnership's Subsidiaries.
 
          E. The General Partner is expressly authorized to enter into, in the
     name and on behalf of the Partnership, a right of first opportunity
     arrangement and other conflict avoidance agreements with various Affiliates
     of the Partnership and the General Partner, on such terms as the General
     Partner, in its sole and absolute discretion, believes are advisable.
 
     Section 7.7  Indemnification.
 
          A. To the fullest extent permitted by applicable law, the Partnership
     shall indemnify each Indemnitee from and against any and all losses,
     claims, damages, liabilities, joint or several, expenses (including,
     without limitation, attorney's fees and other legal fees and expenses),
     judgments, fines, settlements and other amounts arising from any and all
     claims, demands, actions, suits or proceedings, civil, criminal,
     administrative or investigative, that relate to the operations of the
     Partnership ("Actions")
 
                                      B-30
<PAGE>   251
 
     as set forth in this Agreement in which such Indemnitee may be involved, or
     is threatened to be involved, as a party or otherwise; provided, however,
     that the Partnership shall not indemnify an Indemnitee (i) for willful
     misconduct or a knowing violation of the law or (ii) for any transaction
     for which such Indemnitee received an improper personal benefit in
     violation or breach of any provision of this Agreement. Without limitation,
     the foregoing indemnity shall extend to any liability of any Indemnitee,
     pursuant to a loan guaranty or otherwise, for any indebtedness of the
     Partnership or any Subsidiary of the Partnership (including, without
     limitation, any indebtedness which the Partnership or any Subsidiary of the
     Partnership has assumed or taken subject to), and the General Partner is
     hereby authorized and empowered, on behalf of the Partnership, to enter
     into one or more indemnity agreements consistent with the provisions of
     this Section 7.7 in favor of any Indemnitee having or potentially having
     liability for any such indebtedness. It is the intention of this Section
     7.7.A that the Partnership indemnify each Indemnitee to the fullest extent
     permitted by law. The termination of any proceeding by judgment, order or
     settlement does not create a presumption that the Indemnitee did not meet
     the requisite standard of conduct set forth in this Section 7.7.A. The
     termination of any proceeding by conviction of an Indemnitee or upon a plea
     of nolo contendere or its equivalent by an Indemnitee, or an entry of an
     order of probation against an Indemnitee prior to judgment, does not create
     a presumption that such Indemnitee acted in a manner contrary to that
     specified in this Section 7.7.A with respect to the subject matter of such
     proceeding. Any indemnification pursuant to this Section 7.7 shall be made
     only out of the assets of the Partnership, and neither the General Partner
     nor any Limited Partner shall have any obligation to contribute to the
     capital of the Partnership or otherwise provide funds to enable the
     Partnership to fund its obligations under this Section 7.7.
 
          B. To the fullest extent permitted by law, expenses incurred by an
     Indemnitee who is a party to a proceeding or otherwise subject to or the
     focus of or is involved in any Action shall be paid or reimbursed by the
     Partnership as incurred by the Indemnitee in advance of the final
     disposition of the Action upon receipt by the Partnership of (i) a written
     affirmation by the Indemnitee of the Indemnitee's good faith belief that
     the standard of conduct necessary for indemnification by the Partnership as
     authorized in this Section 7.7.A has been met, and (ii) a written
     undertaking by or on behalf of the Indemnitee to repay the amount if it
     shall ultimately be determined that the standard of conduct has not been
     met.
 
          C. The indemnification provided by this Section 7.7 shall be in
     addition to any other rights to which an Indemnitee or any other Person may
     be entitled under any agreement, pursuant to any vote of the Partners, as a
     matter of law or otherwise, and shall continue as to an Indemnitee who has
     ceased to serve in such capacity and shall inure to the benefit of the
     heirs, successors, assigns and administrators of the Indemnitee unless
     otherwise provided in a written agreement with such Indemnitee or in the
     writing pursuant to which such Indemnitee is indemnified.
 
          D. The Partnership may, but shall not be obligated to, purchase and
     maintain insurance, on behalf of any of the Indemnitees and such other
     Persons as the General Partner shall determine, against any liability that
     may be asserted against or expenses that may be incurred by such Person in
     connection with the Partnership's activities, regardless of whether the
     Partnership would have the power to indemnify such Person against such
     liability under the provisions of this Agreement.
 
          E. Any liabilities which an Indemnitee incurs as a result of acting on
     behalf of the Partnership or the General Partner (whether as a fiduciary or
     otherwise) in connection with the operation, administration or maintenance
     of an employee benefit plan or any related trust or funding mechanism
     (whether such liabilities are in the form of excise taxes assessed by the
     IRS, penalties assessed by the Department of Labor, restitutions to such a
     plan or trust or other funding mechanism or to a participant or beneficiary
     of such plan, trust or other funding mechanism, or otherwise) shall be
     treated as liabilities or judgments or fines under this Section 7.7, unless
     such liabilities arise as a result of (i) such Indemnitee's intentional
     misconduct or knowing violation of the law, or (ii) any transaction in
     which such Indemnitee received a personal benefit in violation or breach of
     any provision of this Agreement or applicable law.
 
          F. In no event may an Indemnitee subject any of the Partners to
     personal liability by reason of the indemnification provisions set forth in
     this Agreement.
 
                                      B-31
<PAGE>   252
 
          G. An Indemnitee shall not be denied indemnification in whole or in
     part under this Section 7.7 because the Indemnitee had an interest in the
     transaction with respect to which the indemnification applies if the
     transaction was otherwise permitted by the terms of this Agreement.
 
          H. The provisions of this Section 7.7 are for the benefit of the
     Indemnitees, their heirs, successors, assigns and administrators and shall
     not be deemed to create any rights for the benefit of any other Persons.
     Any amendment, modification or repeal of this Section 7.7 or any provision
     hereof shall be prospective only and shall not in any way affect the
     limitations on the Partnership's liability to any Indemnitee under this
     Section 7.7 as in effect immediately prior to such amendment, modification
     or repeal with respect to claims arising from or relating to matters
     occurring, in whole or in part, prior to such amendment, modification or
     repeal, regardless of when such claims may arise or be asserted.
 
          I. It is the intent of the Partners that any amounts paid by the
     Partnership to the General Partner pursuant to this Section 7.7 shall be
     treated as "guaranteed payments" within the meaning of Code Section 707(c).
 
     Section 7.8  Liability of the General Partner.
 
          A. Notwithstanding anything to the contrary set forth in this
     Agreement, neither the General Partner nor any of its directors or officers
     shall be liable or accountable in damages or otherwise to the Partnership,
     any Partners or any Assignees for losses sustained, liabilities incurred or
     benefits not derived as a result of errors in judgment or mistakes of fact
     or law or of any act or omission if the General Partner or such director or
     officer acted in good faith.
 
          B. The Limited Partners expressly acknowledge that the General Partner
     is acting for the benefit of the Partnership, the Limited Partners and the
     General Partner's shareholders collectively and that the General Partner is
     under no obligation to give priority to the separate interests of the
     Limited Partners or the General Partner's shareholders (including, without
     limitation, the tax consequences to Limited Partners, Assignees or the
     General Partner's shareholders) in deciding whether to cause the
     Partnership to take (or decline to take) any actions.
 
          C. Subject to its obligations and duties as General Partner set forth
     in Section 7.1.A hereof, the General Partner may exercise any of the powers
     granted to it by this Agreement and perform any of the duties imposed upon
     it hereunder either directly or by or through its employees or agents
     (subject to the supervision and control of the General Partner). The
     General Partner shall not be responsible for any misconduct or negligence
     on the part of any such agent appointed by it in good faith.
 
          D. Any amendment, modification or repeal of this Section 7.8 or any
     provision hereof shall be prospective only and shall not in any way affect
     the limitations on the General Partner's, and its officers' and directors',
     liability to the Partnership and the Limited Partners under this Section
     7.8 as in effect immediately prior to such amendment, modification or
     repeal with respect to claims arising from or relating to matters
     occurring, in whole or in part, prior to such amendment, modification or
     repeal, regardless of when such claims may arise or be asserted.
 
          E. Notwithstanding anything herein to the contrary, except for fraud,
     willful misconduct or gross negligence, or pursuant to any express
     indemnities given to the Partnership by any Partner pursuant to any other
     written instrument, no Partner shall have any personal liability
     whatsoever, to the Partnership or to the other Partner(s), for the debts or
     liabilities of the Partnership or the Partnership's obligations hereunder,
     and the full recourse of the other Partner(s) shall be limited to the
     interest of that Partner in the Partnership. To the fullest extent
     permitted by law, no officer, director or shareholder of the General
     Partner shall be liable to the Partnership for money damages except for (i)
     active and deliberate dishonesty established by a non-appealable final
     judgment or (ii) actual receipt of an improper benefit or profit in money,
     property or services. Without limitation of the foregoing, and except for
     fraud, willful misconduct or gross negligence, or pursuant to any such
     express indemnity, no property or assets of any Partner, other than its
     interest in the Partnership, shall be subject to levy, execution or other
     enforcement procedures for the satisfaction of any judgment (or other
     judicial process) in favor of any other
 
                                      B-32
<PAGE>   253
 
     Partner(s) and arising out of, or in connection with, this Agreement. This
     Agreement is executed by the officers of the General Partner solely as
     officers of the same and not in their own individual capacities.
 
          F. To the extent that, at law or in equity, the General Partner has
     duties (including fiduciary duties) and liabilities relating thereto to the
     Partnership or the Limited Partners, the General Partner shall not be
     liable to the Partnership or to any other Partner for its good faith
     reliance on the provisions of this Agreement. The provisions of this
     Agreement, to the extent that they restrict the duties and liabilities of
     the General Partner otherwise existing at law or in equity, are agreed by
     the Partners to replace such other duties and liabilities of such General
     Partner.
 
     Section 7.9  Other Matters Concerning the General Partner.
 
          A. The General Partner may rely and shall be protected in acting or
     refraining from acting upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, bond,
     debenture or other paper or document believed by it in good faith to be
     genuine and to have been signed or presented by the proper party or
     parties.
 
          B. The General Partner may consult with legal counsel, accountants,
     appraisers, management consultants, investment bankers, architects,
     engineers, environmental consultants and other consultants and advisers
     selected by it, and any act taken or omitted to be taken in reliance upon
     the opinion of such Persons as to matters that the General Partner
     reasonably believes to be within such Person's professional or expert
     competence shall be conclusively presumed to have been done or omitted in
     good faith and in accordance with such opinion.
 
          C. The General Partner shall have the right, in respect of any of its
     powers or obligations hereunder, to act through any of its duly authorized
     officers and a duly appointed attorney or attorneys-in-fact. Each such
     attorney shall, to the extent provided by the General Partner in the power
     of attorney, have full power and authority to do and perform all and every
     act and duty that is permitted or required to be done by the General
     Partner hereunder.
 
          D. Notwithstanding any other provision of this Agreement or the Act,
     any action of the General Partner on behalf of the Partnership or any
     decision of the General Partner to refrain from acting on behalf of the
     Partnership, undertaken in the good faith belief that such action or
     omission is necessary or advisable in order (i) to protect the ability of
     the Previous General Partner to continue to qualify as a REIT, (ii) for the
     Previous General Partner otherwise to satisfy the REIT Requirements, (iii)
     to avoid the Previous General Partner incurring any taxes under Code
     Section 857 or Code Section 4981 or (iv) for the General Partner or the
     Special Limited Partner to continue to qualify as a "qualified REIT
     subsidiary" (within the meaning of Code Section 856(i)(2)), is expressly
     authorized under this Agreement and is deemed approved by all of the
     Limited Partners.
 
     Section 7.10  Title to Partnership Assets. Title to Partnership assets,
whether real, personal or mixed and whether tangible or intangible, shall be
deemed to be owned by the Partnership as an entity, and no Partner, individually
or collectively with other Partners or Persons, shall have any ownership
interest in such Partnership assets or any portion thereof. Title to any or all
of the Partnership assets may be held in the name of the Partnership, the
General Partner or one or more nominees, as the General Partner may determine,
including Affiliates of the General Partner. The General Partner hereby declares
and warrants that any Partnership assets for which legal title is held in the
name of the General Partner or any nominee or Affiliate of the General Partner
shall be held by the General Partner for the use and benefit of the Partnership
in accordance with the provisions of this Agreement; provided, however, that the
General Partner shall use its best efforts to cause beneficial and record title
to such assets to be vested in the Partnership as soon as reasonably
practicable. All Partnership assets shall be recorded as the property of the
Partnership in its books and records, irrespective of the name in which legal
title to such Partnership assets is held.
 
     Section 7.11  Reliance by Third Parties. Notwithstanding anything to the
contrary in this Agreement, any Person dealing with the Partnership shall be
entitled to assume that the General Partner has full power and authority,
without the consent or approval of any other Partner or Person, to encumber,
sell or otherwise
                                      B-33
<PAGE>   254
 
use in any manner any and all assets of the Partnership and to enter into any
contracts on behalf of the Partnership, and take any and all actions on behalf
of the Partnership, and such Person shall be entitled to deal with the General
Partner as if it were the Partnership's sole party in interest, both legally and
beneficially. Each Limited Partner hereby waives any and all defenses or other
remedies that may be available against such Person to contest, negate or
disaffirm any action of the General Partner in connection with any such dealing.
In no event shall any Person dealing with the General Partner or its
representatives be obligated to ascertain that the terms of this Agreement have
been complied with or to inquire into the necessity or expediency of any act or
action of the General Partner or its representatives. Each and every
certificate, document or other instrument executed on behalf of the Partnership
by the General Partner or its representatives shall be conclusive evidence in
favor of any and every Person relying thereon or claiming thereunder that (i) at
the time of the execution and delivery of such certificate, document or
instrument, this Agreement was in full force and effect, (ii) the Person
executing and delivering such certificate, document or instrument was duly
authorized and empowered to do so for and on behalf of the Partnership and (iii)
such certificate, document or instrument was duly executed and delivered in
accordance with the terms and provisions of this Agreement and is binding upon
the Partnership.
 
                                   ARTICLE 8
 
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS
 
     Section 8.1  Limitation of Liability. The Limited Partners shall have no
liability under this Agreement except as expressly provided in this Agreement
(including, without limitation, Section 10.4 hereof) or under the Act.
 
     Section 8.2  Management of Business. No Limited Partner or Assignee (other
than the General Partner, any of its Affiliates or any officer, director,
member, employee, partner, agent or trustee of the General Partner, the
Partnership or any of their Affiliates, in their capacity as such) shall take
part in the operations, management or control (within the meaning of the Act) of
the Partnership's business, transact any business in the Partnership's name or
have the power to sign documents for or otherwise bind the Partnership. The
transaction of any such business by the General Partner, any of its Affiliates
or any officer, director, member, employee, partner, agent, representative, or
trustee of the General Partner, the Partnership or any of their Affiliates, in
their capacity as such, shall not affect, impair or eliminate the limitations on
the liability of the Limited Partners or Assignees under this Agreement.
 
     Section 8.3  Outside Activities of Limited Partners. Subject to any
agreements entered into pursuant to Section 7.6.D hereof and any other
agreements entered into by a Limited Partner or its Affiliates with the General
Partner, the Partnership or a Subsidiary (including, without limitation, any
employment agreement), any Limited Partner and any Assignee, officer, director,
employee, agent, trustee, Affiliate or shareholder of any Limited Partner shall
be entitled to and may have business interests and engage in business activities
in addition to those relating to the Partnership, including business interests
and activities that are in direct or indirect competition with the Partnership
or that are enhanced by the activities of the Partnership. Neither the
Partnership nor any Partners shall have any rights by virtue of this Agreement
in any business ventures of any Limited Partner or Assignee. Subject to such
agreements, none of the Limited Partners nor any other Person shall have any
rights by virtue of this Agreement or the partnership relationship established
hereby in any business ventures of any other Person (other than the General
Partner, to the extent expressly provided herein), and such Person shall have no
obligation pursuant to this Agreement, subject to Section 7.6.D hereof and any
other agreements entered into by a Limited Partner or its Affiliates with the
General Partner, the Partnership or a Subsidiary, to offer any interest in any
such business ventures to the Partnership, any Limited Partner or any such other
Person, even if such opportunity is of a character that, if presented to the
Partnership, any Limited Partner or such other Person, could be taken by such
Person.
 
     Section 8.4  Return of Capital. Except pursuant to the rights of Redemption
set forth in Section 8.6 hereof, no Limited Partner shall be entitled to the
withdrawal or return of its Capital Contribution, except to the extent of
distributions made pursuant to this Agreement or upon termination of the
Partnership as provided herein. Except to the extent provided in Article 6
hereof or otherwise expressly provided in this
                                      B-34
<PAGE>   255
 
Agreement, no Limited Partner or Assignee shall have priority over any other
Limited Partner or Assignee either as to the return of Capital Contributions or
as to profits, losses or distributions.
 
     Section 8.5  Rights of Limited Partners Relating to the Partnership.
 
          A. In addition to other rights provided by this Agreement or by the
     Act, and except as limited by Section 8.5.C hereof, each Limited Partner
     shall have the right, for a purpose reasonably related to such Limited
     Partner's interest as a limited partner in the Partnership, upon written
     demand with a statement of the purpose of such demand and at such Limited
     Partner's own expense:
 
             (1) to obtain a copy of (i) the most recent annual and quarterly
        reports filed with the SEC by the Previous General Partner or the
        General Partner pursuant to the Exchange Act and (ii) each report or
        other written communication sent to the shareholders of the Previous
        General Partner;
 
             (2) to obtain a copy of the Partnership's federal, state and local
        income tax returns for each Fiscal Year;
 
             (3) to obtain a current list of the name and last known business,
        residence or mailing address of each Partner;
 
             (4) to obtain a copy of this Agreement and the Certificate and all
        amendments thereto, together with executed copies of all powers of
        attorney pursuant to which this Agreement, the Certificate and all
        amendments thereto have been executed; and
 
             (5) to obtain true and full information regarding the amount of
        cash and a description and statement of any other property or services
        contributed by each Partner and that each Partner has agreed to
        contribute in the future, and the date on which each became a Partner.
 
          B. The Partnership shall notify any Limited Partner that is a
     Qualifying Party, on request, of the then current Adjustment Factor or any
     change made to the Adjustment Factor.
 
          C. Notwithstanding any other provision of this Section 8.5, the
     General Partner may keep confidential from the Limited Partners, for such
     period of time as the General Partner determines in its sole and absolute
     discretion to be reasonable, any information that (i) the General Partner
     believes to be in the nature of trade secrets or other information the
     disclosure of which the General Partner in good faith believes is not in
     the best interests of the Partnership or the General Partner or (ii) the
     Partnership or the General Partner is required by law or by agreements with
     unaffiliated third parties to keep confidential.
 
     Section 8.6  Redemption Rights of Qualifying Parties.
 
          A. After the first Twelve-Month Period, a Qualifying Party, but no
     other Limited Partner or Assignee, 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 Redeemable Units held by such Tendering Party (such
     Redeemable Units being hereafter "Tendered Units") in exchange (a
     "Redemption") for the Cash Amount payable on the Specified Redemption Date.
     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"). The Partnership's obligation
     to effect a Redemption, however, shall not arise or be binding against the
     Partnership (i) until and unless there has been a Declination and (ii)
     before the Business Day following the Cut-Off Date. Regardless of the
     binding or non-binding nature of a pending Redemption, 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 Partnership Record Date for such
     distribution precedes or coincides with such delivery of the Notice of
     Redemption. In the event of a Redemption, the Cash Amount 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.
 
                                      B-35
<PAGE>   256
 
          B. Notwithstanding the provisions of Section 8.6.A hereof, on or
     before the close of business on the Cut-Off Date, the General Partner may,
     in its sole and absolute discretion but subject to the Ownership Limit and
     the transfer restrictions and other limitations of the Charter, elect to
     cause the Previous General Partner to acquire some or all (such percentage
     being referred to as the "Applicable Percentage") of the Tendered Units
     from the Tendering Party in exchange for REIT Shares. In making such
     election to cause the Previous General Partner to acquire Tendered Units,
     the General Partner shall act in a fair, equitable and reasonable manner
     that neither prefers one group or class of Qualifying Parties over another
     nor discriminates against a group or class of Qualifying Parties. If the
     General Partner so elects, on the Specified Redemption Date the Tendering
     Party shall sell such number of the Tendered Units to the Previous General
     Partner in exchange for a number of REIT Shares equal to the product of the
     REIT Shares Amount and the Applicable Percentage. 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 General Partner's view, to effect compliance with the Securities
     Act. In the event of a purchase of the Tendered Units by the Previous
     General Partner pursuant to this Section 8.6.B, the Tendering Party shall
     no longer have the right to cause the Partnership to effect a Redemption of
     such Tendered Units, and, upon notice to the Tendering Party by the General
     Partner or the Previous General Partner, given on or before the close of
     business on the Cut-Off Date, that the Previous General Partner has elected
     to acquire some or all of the Tendered Units pursuant to this Section
     8.6.B, the obligation of the Partnership to effect a Redemption of the
     Tendered Units as to which the General Partner's notice relates shall not
     accrue or arise. The product of the Applicable Percentage and the REIT
     Shares Amount, if applicable, shall be delivered by the Previous General
     Partner as duly authorized, validly issued, fully paid and accessible REIT
     Shares and, if applicable, Rights, 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 8.6.B, 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 REIT Shares
     are issued pursuant to this Section 8.6.B, 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 REIT Shares
     and Rights for all purposes, including, without limitation, rights to vote
     or consent, receive dividends, and exercise rights, as of the Specified
     Redemption Date. REIT Shares issued upon an acquisition of the Tendered
     Units by the Previous General Partner pursuant to this Section 8.6.B 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.
 
          C. Notwithstanding the provisions of Section 8.6.A and 8.6.B hereof,
     the Tendering Parties (i) where the Redemption would consist of less than
     all the Partnership Common Units held by Partners other than the General
     Partner and the Special Limited Partner, shall not be entitled to elect or
     effect a Redemption to the extent that the aggregate Percentage Interests
     of the Limited Partners (other than the Special Limited Partner) would be
     reduced, as a result of the Redemption (or the acquisition of the Tendered
     Units by the Previous General Partner pursuant to Section 8.6.B hereof), to
     less than one percent (1%) and (ii) shall have no rights under this
     Agreement that would otherwise be prohibited under the Charter. To the
     extent that any attempted Redemption or acquisition of the Tendered Units
     by the Previous General Partner pursuant to Section 8.6.B hereof would be
     in violation of this Section 8.6.C, it shall be null and void ab initio,
     and the Tendering Party shall not acquire any rights or economic interests
     in REIT Shares otherwise issuable by the Previous General Partner under
     Section 8.6.B hereof.
 
                                      B-36
<PAGE>   257
 
          D. In the event that the Previous General Partner declines or fails to
     exercise its purchase rights pursuant to Section 8.6.B hereof following
     receipt of a Notice of Redemption (a "Declination"):
 
             (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. The failure of both the Previous
        General Partner and the General Partner to give notice of such
        Declination by the close of business on the Cut-Off Date shall itself
        constitute a Declination.
 
             (2) The Partnership may elect to raise funds for the payment of the
        Cash Amount either (a) by requiring that the 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 REIT
        Shares ("Registrable Shares") equal to the REIT 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 Previous General Partner's Declination, the General
        Partner shall give notice (a "Single Funding Notice") to all Qualifying
        Parties then holding a Partnership Interest (or an interest therein) and
        having Redemption rights pursuant to this Section 8.6 and require that
        all such Qualifying Parties elect whether or not to effect a Redemption
        of their Partnership Common 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 Partnership Common 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 8.6. 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 current Twelve-Month Period;
        provided, however, that the Previous General Partner shall not be
        required to acquire Partnership Common Units pursuant to this Section
        8.6.D more than twice within a 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.
 
          E. Notwithstanding the provisions of Section 8.6.B hereof, the
     Previous General Partner shall not, under any circumstances, elect to
     acquire Tendered Units in exchange for the REIT Shares Amount if such
     exchange would be prohibited under the Charter.
 
          F. Notwithstanding anything herein to the contrary (but subject to
     Section 8.6.C hereof), with respect to any Redemption (or any tender of
     Redeemable Units for Redemption if the Tendered Units are acquired by the
     Previous General Partner pursuant to Section 8.6.B hereof) pursuant to this
     Section 8.6:
 
             (1) All Partnership Common Units acquired by the Previous General
        Partner pursuant to Section 8.6.B hereof shall be contributed by the
        Previous General 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. Any Partnership Common Units so contributed to the General
        Partner shall automatically, and without further action required, be
        converted into and deemed to be a General Partner Interest comprised of
        the same number of Partnership Common Units. Any Partnership Common
        Units so contributed to the Special Limited Partner shall remain
        outstanding.
 
             (2) Subject to the Ownership Limit, no Tendering Party may effect a
        Redemption for less than five hundred (500) Redeemable Units or, if such
        Tendering Party holds (as a Limited Partner or,
                                      B-37
<PAGE>   258
 
        economically, as an Assignee) less than five hundred (500) Redeemable
        Units, all of the Redeemable 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 Section 8.6.B hereof, 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 8.6.E
        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 (or an acquisition of
        Tendered Units by the Previous General Partner pursuant to Section 8.6.B
        hereof, as the case may be) 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 hereof) all Redeemable
        Units subject to any Redemption, and be treated as a Limited Partner or
        an Assignee, as applicable, with respect to such Redeemable Units for
        all purposes of this Agreement, until such Redeemable Units are either
        paid for by the Partnership pursuant to Section 8.6.A hereof 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 Section 8.6.B hereof on the Specified
        Redemption Date. Until a Specified Redemption Date and an acquisition of
        the Tendered Units by the Previous General Partner pursuant to Section
        8.6.B hereof, 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 8.6.F, all Partnership Common Units beneficially owned by a
     Related Party of a Tendering Party shall be considered to be owned or held
     by such Tendering Party.
 
          G. In connection with an exercise of Redemption rights pursuant to
     this Section 8.6, 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 REIT
        Shares by (i) such Tendering Party and (ii) any Related Party and (b)
        representing that, after giving effect to the Redemption or an
        acquisition of the Tendered Units by the Previous General Partner
        pursuant to Section 8.6.B hereof, neither the Tendering Party nor any
        Related Party will own REIT 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 REIT
        Shares prior to the closing of the Redemption or an acquisition of the
        Tendered Units by the Previous General Partner pursuant to Section 8.6.B
        hereof on the Specified Redemption Date; and
                                      B-38
<PAGE>   259
 
             (3) An undertaking to certify, at and as a condition to the closing
        of (i) the Redemption or (ii) the acquisition of the Tendered Units by
        the Previous General Partner pursuant to Section 8.6.B hereof on the
        Specified Redemption Date, that either (a) the actual and constructive
        ownership of REIT Shares by the Tendering Party and any Related Party
        remain unchanged from that disclosed in the affidavit required by
        Section 8.6.G(1) or (b) after giving effect to the Redemption or an
        acquisition of the Tendered Units by the Previous General Partner
        pursuant to Section 8.6.B hereof, neither the Tendering Party nor any
        Related Party shall own REIT Shares in violation of the Ownership Limit.
 
     Section 8.7  Partnership Right to Call Limited Partner
Interests. Notwithstanding any other provision of this 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 Section 8.6 hereof for the amount of Partnership Common 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 8.7. Such notice given by the General Partner to a Limited
Partner pursuant to this Section 8.7 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 8.7, (a) any Limited Partner (whether or not otherwise
a Qualifying Party) may, in the General Partner's sole and absolute discretion,
be treated as a Qualifying Party that is a Tendering Party and (b) the
provisions of Sections 8.6.C(1), 8.6.F(2), 8.6.F(3) and 8.6.F(5) hereof shall
not apply, but the remainder of Section 8.6 hereof shall apply, mutatis
mutandis.

     Section 9.1  Records and Accounting.
 
          A. The General Partner shall keep or cause to be kept at the principal
     office of the Partnership those records and documents required to be
     maintained by the Act and other books and records deemed by the General
     Partner to be appropriate with respect to the Partnership's business,
     including, without limitation, all books and records necessary to provide
     to the Limited Partners any information, lists and copies of documents
     required to be provided pursuant to Section 8.5.A or Section 9.3 hereof.
     Any records maintained by or on behalf of the Partnership in the regular
     course of its business may be kept on, or be in the form for, punch cards,
     magnetic tape, photographs, micrographics or any other information storage
     device, provided that the records so maintained are convertible into
     clearly legible written form within a reasonable period of time.
 
          B. The books of the Partnership shall be maintained, for financial and
     tax reporting purposes, on an accrual basis in accordance with generally
     accepted accounting principles, or on such other basis as the General
     Partner determines to be necessary or appropriate. To the extent permitted
     by sound accounting practices and principles, the Partnership, the General
     Partner and the Previous General Partner may operate with integrated or
     consolidated accounting records, operations and principles.
 
     Section 9.2  Fiscal Year. The Fiscal Year of the Partnership shall be the
calendar year.
 
     Section 9.3  Reports.
 
          A. As soon as practicable, but in no event later than one hundred five
     (105) days after the close of each Fiscal Year, the General Partner shall
     cause to be mailed to each Limited Partner, of record as of the close of
     the Fiscal Year, an annual report containing financial statements of the
     Partnership, or of the Previous General Partner if such statements are
     prepared solely on a consolidated basis with the Previous General Partner,
     for such Fiscal Year, presented in accordance with generally accepted
     accounting

     principles, such statements to be audited by a nationally recognized firm
     of independent public accountants selected by the General Partner.
 
          B. As soon as practicable, but in no event later than one hundred five
     (105) days after the close of each calendar quarter (except the last
     calendar quarter of each year), the General Partner shall cause to be
     mailed to each Limited Partner, of record as of the last day of the
     calendar quarter, a report containing unaudited financial statements of the
     Partnership, or of the Previous General Partner if such statements are
     prepared solely on a consolidated basis with the Previous General Partner,
     and such other information as may be required by applicable law or
     regulation or as the General Partner determines to be appropriate. At the
     request of any Limited Partner, the General Partner shall provide access to
     the books, records and workpapers upon which the reports required by this
     Section 9.3 are based, to the extent required by the Act.
 
                                   ARTICLE 10
 
                                  TAX MATTERS
 
     Section 10.1  Preparation of Tax Returns. The General Partner shall arrange
for the preparation and timely filing of all returns with respect to Partnership
income, gains, deductions, losses and other items required of the Partnership
for federal and state income tax purposes and shall use all reasonable effort to
furnish, within ninety (90) days of the close of each taxable year, the tax
information reasonably required by Limited Partners for federal and state income
tax reporting purposes. The Limited Partners shall promptly provide the General
Partner with such information relating to the Contributed Properties, including
tax basis and other relevant information, as may be reasonably requested by the
General Partner from time to time.
 
     Section 10.2  Tax Elections. Except as otherwise provided herein, the
General Partner shall, in its sole and absolute discretion, determine whether to
make any available election pursuant to the Code, including, but not limited to,
the election under Code Section 754 and the election to use the "recurring item"
method of accounting provided under Code Section 461(h) with respect to property
taxes imposed on the Partnership's Properties; provided, however, that, if the
"recurring item" method of accounting is elected with respect to such property
taxes, the Partnership shall pay the applicable property taxes prior to the date
provided in Code Section 461(h) for purposes of determining economic
performance. The General Partner shall have the right to seek to revoke any such
election (including, without limitation, any election under Code Sections 461(h)
and 754) upon the General Partner's determination in its sole and absolute
discretion that such revocation is in the best interests of the Partners.
 
     Section 10.3  Tax Matters Partner.
 
          A. The General Partner shall be the "tax matters partner" of the
     Partnership for federal income tax purposes. The tax matters partner shall
     receive no compensation for its services. All third-party costs and
     expenses incurred by the tax matters partner in performing its duties as
     such (including legal and accounting fees and expenses) shall be borne by
     the Partnership in addition to any reimbursement pursuant to Section 7.4
     hereof. Nothing herein shall be construed to restrict the Partnership from
     engaging an accounting firm to assist the tax matters partner in
     discharging its duties hereunder, so long as the compensation paid by the
     Partnership for such services is reasonable. At the request of any Limited
     Partner, the General Partner agrees to consult with such Limited Partner
     with respect to the preparation and filing of any returns and with respect
     to any subsequent audit or litigation relating to such returns; provided,
     however, that the filing of such returns shall be in the sole and absolute
     discretion of the General Partner.
 
          B. The tax matters partner is authorized, but not required:
 
             (1) to enter into any settlement with the IRS with respect to any
        administrative or judicial proceedings for the adjustment of Partnership
        items required to be taken into account by a Partner for income tax
        purposes (such administrative proceedings being referred to as a "tax
        audit" and such judicial proceedings being referred to as "judicial
        review"), and in the settlement agreement the tax
 
                                      B-40
<PAGE>   261
 
        matters partner may expressly state that such agreement shall bind all
        Partners, except that such settlement agreement shall not bind any
        Partner (i) who (within the time prescribed pursuant to the Code and
        Regulations) files a statement with the IRS providing that the tax
        matters partner shall not have the authority to enter into a settlement
        agreement on behalf of such Partner or (ii) who is a "notice partner"
        (as defined in Code Section 6231) or a member of a "notice group" (as
        defined in Code Section 6223(b)(2));
 
             (2) in the event that a notice of a final administrative adjustment
        at the Partnership level of any item required to be taken into account
        by a Partner for tax purposes (a "final adjustment") is mailed to the
        tax matters partner, to seek judicial review of such final adjustment,
        including the filing of a petition for readjustment with the United
        States Tax Court or the United States Claims Court, or the filing of a
        complaint for refund with the District Court of the United States for
        the district in which the Partnership's principal place of business is
        located;
 
             (3) to intervene in any action brought by any other Partner for
        judicial review of a final adjustment;
 
             (4) to file a request for an administrative adjustment with the IRS
        at any time and, if any part of such request is not allowed by the IRS,
        to file an appropriate pleading (petition or complaint) for judicial
        review with respect to such request;
 
             (5) to enter into an agreement with the IRS to extend the period
        for assessing any tax that is attributable to any item required to be
        taken into account by a Partner for tax purposes, or an item affected by
        such item; and
 
             (6) to take any other action on behalf of the Partners in
        connection with any tax audit or judicial review proceeding to the
        extent permitted by applicable law or regulations.
 
     The taking of any action and the incurring of any expense by the tax
     matters partner in connection with any such proceeding, except to the
     extent required by law, is a matter in the sole and absolute discretion of
     the tax matters partner and the provisions relating to indemnification of
     the General Partner set forth in Section 7.7 hereof shall be fully
     applicable to the tax matters partner in its capacity as such.
 
     Section 10.4  Withholding. Each Limited Partner hereby authorizes the
Partnership to withhold from or pay on behalf of or with respect to such Limited
Partner any amount of federal, state, local or foreign taxes that the General
Partner determines that the Partnership is required to withhold or pay with
respect to any amount distributable or allocable to such Limited Partner
pursuant to this Agreement, including, without limitation, any taxes required to
be withheld or paid by the Partnership pursuant to Code Section 1441, Code
Section 1442, Code Section 1445 or Code Section 1446. Any amount paid on behalf
of or with respect to a Limited Partner shall constitute a loan by the
Partnership to such Limited Partner, which loan shall be repaid by such Limited
Partner within fifteen (15) days after notice from the General Partner that such
payment must be made unless (i) the Partnership withholds such payment from a
distribution that would otherwise be made to the Limited Partner or (ii) the
General Partner determines, in its sole and absolute discretion, that such
payment may be satisfied out of the Available Funds of the Partnership that
would, but for such payment, be distributed to the Limited Partner. Each Limited
Partner hereby unconditionally and irrevocably grants to the Partnership a
security interest in such Limited Partner's Partnership Interest to secure such
Limited Partner's obligation to pay to the Partnership any amounts required to
be paid pursuant to this Section 10.4. In the event that a Limited Partner fails
to pay any amounts owed to the Partnership pursuant to this Section 10.4 when
due, the General Partner may, in its sole and absolute discretion, elect to make
the payment to the Partnership on behalf of such defaulting Limited Partner, and
in such event shall be deemed to have loaned such amount to such defaulting
Limited Partner and shall succeed to all rights and remedies of the Partnership
as against such defaulting Limited Partner (including, without limitation, the
right to receive distributions). Any amounts payable by a Limited Partner
hereunder shall bear interest at the base rate on corporate loans at large
United States money center commercial banks, as published from time to time in
the Wall Street Journal, plus four (4) percentage points (but not higher than
the maximum lawful rate) from the date such amount is due (i.e., fifteen (15)
days after demand) until such amount is paid in full. Each Limited
                                      B-41
<PAGE>   262
 
Partner shall take such actions as the Partnership or the General Partner shall
request in order to perfect or enforce the security interest created hereunder.

                           TRANSFERS AND WITHDRAWALS
 
     Section 11.1  Transfer.
 
          A. No part of the interest of a Partner shall be subject to the claims
     of any creditor, to any spouse for alimony or support, or to legal process,
     and may not be voluntarily or involuntarily alienated or encumbered except
     as may be specifically provided for in this Agreement.
 
          B. No Partnership Interest shall be Transferred, in whole or in part,
     except in accordance with the terms and conditions set forth in this
     Article 11. Any Transfer or purported Transfer of a Partnership Interest
     not made in accordance with this Article 11 shall be null and void ab
     initio.
 
          C. Notwithstanding the other provisions of this Article 11 (other than
     Section 11.6.D hereof), the Partnership Interests of the General Partner
     and the Special Limited Partner may be Transferred, in whole or in part, at
     any time or from time to time, to or among the Previous General Partner,
     the General Partner, the Special Limited Partner, and any other Person that
     is, at the time of such Transfer, a "qualified REIT subsidiary" (within the
     meaning of Code Section 856(i)(2)) with respect to the Previous General
     Partner. Any transferee of the entire General Partner Interest pursuant to
     this Section 11.1.C shall automatically become, without further action or
     Consent of any Limited Partners, the sole general partner of the
     Partnership, subject to all the rights, privileges, duties and obligations
     under this Agreement and the Act relating to a general partner. Any
     transferee of a Limited Partner Interest pursuant to this Section 11.1.C
     shall automatically become, without further action or Consent of any
     Limited Partners, a Substituted Limited Partner. Upon any Transfer
     permitted by this Section 11.1.C, the transferor Partner shall be relieved
     of all its obligations under this Agreement. The provisions of Section
     11.2.B (other than the last sentence thereof), 11.3, 11.4.A and 11.5 hereof
     shall not apply to any Transfer permitted by this Section 11.1.C.
 
     Section 11.2  Transfer of General Partner's Partnership Interest.
 
          A. The General Partner may not Transfer any of its General Partner
     Interest or withdraw from the Partnership except as provided in Sections
     11.2.B and 11.2.C hereof.
 
          B. The General Partner shall not withdraw from the Partnership and
     shall not Transfer all or any portion of its interest in the Partnership
     (whether by sale, disposition, statutory merger or consolidation,
     liquidation or otherwise) without the Consent of the Limited Partners,
     which Consent may be given or withheld in the sole and absolute discretion
     of the Limited Partners. Upon any Transfer of such a Partnership Interest
     pursuant to the Consent of the Limited Partners and otherwise in accordance
     with the provisions of this Section 11.2.B, the transferee shall become a
     successor General Partner for all purposes herein, and shall be vested with
     the powers and rights of the transferor General Partner, and shall be
     liable for all obligations and responsible for all duties of the General
     Partner, once such transferee has executed such instruments as may be
     necessary to effectuate such admission and to confirm the agreement of such
     transferee to be bound by all the terms and provisions of this Agreement
     with respect to the Partnership Interest so acquired. It is a condition to
     any Transfer otherwise permitted hereunder that the transferee assumes, by
     operation of law or express agreement, all of the obligations of the
     transferor General Partner under this Agreement with respect to such
     Transferred Partnership Interest, and such Transfer shall relieve the
     transferor General Partner of its obligations under this Agreement without
     the Consent of the Limited Partners. In the event that the General Partner
     withdraws from the Partnership, in violation of this Agreement or
     otherwise, or otherwise dissolves or terminates, or upon the bankruptcy of
     the General Partner, a Majority in Interest of the Limited Partners may
     elect to continue the Partnership business by selecting a successor General
     Partner in accordance with the Act.

          C. The General Partner may merge with another entity if immediately
     after such merger substantially all of the assets of the surviving entity,
     other than the General Partner Interest held by the General Partner, are
     contributed to the Partnership as a Capital Contribution in exchange for
     Partnership Units.
 
     Section 11.3  Limited Partners' Rights to Transfer.
 
          A. General. Prior to the end of the first Twelve-Month Period, no
     Limited Partner shall Transfer all or any portion of its Partnership
     Interest to any transferee without the Consent of the General Partner,
     which Consent may be withheld in its sole and absolute discretion;
     provided, however, that any Limited Partner may, at any time, without the
     consent of the General Partner, (i) Transfer all or part of its Partnership
     Interest to any Designated Party, any Family Member, any Controlled Entity
     or any Affiliate, provided that the transferee is, in any such case, a
     Qualified Transferee, or (ii) pledge (a "Pledge") all or any portion of its
     Partnership Interest to a lending institution, that is not an Affiliate of
     such Limited Partner, as collateral or security for a bona fide loan or
     other extension of credit, and Transfer such pledged Partnership Interest
     to such lending institution in connection with the exercise of remedies
     under such loan or extension or credit (any Transfer or Pledge permitted by
     this proviso is hereinafter referred to as a "Permitted Transfer"). After
     such first Twelve-Month Period, each Limited Partner, and each transferee
     of Partnership Units or Assignee pursuant to a Permitted Transfer, shall
     have the right to Transfer all or any portion of its Partnership Interest
     to any Person, subject to the provisions of Section 11.6 hereof and to
     satisfaction of each of the following conditions:
 
             (1) General Partner Right of First Refusal. The transferring
        Partner shall give written notice of the proposed Transfer to the
        General Partner, which notice shall state (i) the identity of the
        proposed transferee and (ii) the amount and type of consideration
        proposed to be received for the Transferred Partnership Units. The
        General Partner shall have ten (10) Business Days upon which to give the
        Transferring Partner notice of its election to acquire the Partnership
        Units on the proposed terms. If it so elects, it shall purchase the
        Partnership Units on such terms within ten (10) Business Days after
        giving notice of such election; provided, however, that in the event
        that the proposed terms involve a purchase for cash, the General Partner
        may at its election deliver in lieu of all or any portion of such cash a
        note payable to the Transferring Partner at a date as soon as reasonably
        practicable, but in no event later than one hundred eighty (180) days
        after such purchase, and bearing interest at an annual rate equal to the
        total dividends declared with respect to one (1) REIT Share for the four
        (4) preceding fiscal quarters of the General Partner, divided by the
        Value as of the closing of such purchase; provided, further, that such
        closing may be deferred to the extent necessary to effect compliance
        with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if
        applicable, and any other applicable requirements of law. If it does not
        so elect, the Transferring Partner may Transfer such Partnership Units
        to a third party, on terms no more favorable to the transferee than the
        proposed terms, subject to the other conditions of this Section 11.3.
 
             (2) Qualified Transferee. Any Transfer of a Partnership Interest
        shall be made only to a single Qualified Transferee; provided, however,
        that, for such purposes, all Qualified Transferees that are Affiliates,
        or that comprise investment accounts or funds managed by a single
        Qualified Transferee and its Affiliates, shall be considered together to
        be a single Qualified Transferee; provided, further, that each Transfer
        meeting the minimum Transfer restriction of Section 11.3.A(3) hereof may
        be to a separate Qualified Transferee.
 
             (3) Minimum Transfer Restriction. Any Transferring Partner must
        Transfer not less than the lesser of (i) the greater of five hundred
        (500) Partnership Units or one-third ( 1/3) of the number of Partnership
        Units owned by such Partner as of the Effective Date or (ii) all of the
        remaining Partnership Units owned by such Transferring Partner;
        provided, however, that, for purposes of determining compliance with the
        foregoing restriction, all Partnership Units owned by Affiliates of a
        Limited Partner shall be considered to be owned by such Limited Partner.

<PAGE>   264
 
             (4) Transferee Agreement to Effect a Redemption. Any proposed
        transferee shall deliver to the General Partner a written agreement
        reasonably satisfactory to the General Partner to the effect that the
        transferee will, within six (6) months after consummation of a
        Partnership Common Units Transfer, tender its Partnership Common Units
        for Redemption in accordance with the terms of the Redemption rights
        provided in Section 8.6 hereof.
 
             (5) No Further Transfers. The transferee (other than a Designated
        Party) shall not be permitted to effect any further Transfer of the
        Partnership Units, other than to the General Partner.
 
             (6) Exception for Permitted Transfers. The conditions of Sections
        11.3.A(1) through 11.3.A(5) hereof shall not apply in the case of a
        Permitted Transfer.
 
     It is a condition to any Transfer otherwise permitted hereunder (whether or
     not such Transfer is effected during or after the first Twelve-Month
     Period) that the transferee assumes by operation of law or express
     agreement all of the obligations of the transferor Limited Partner under
     this Agreement with respect to such Transferred Partnership Interest, and
     no such Transfer (other than pursuant to a statutory merger or
     consolidation wherein all obligations and liabilities of the transferor
     Partner are assumed by a successor corporation by operation of law) shall
     relieve the transferor Partner of its obligations under this Agreement
     without the approval of the General Partner, in its sole and absolute
     discretion. Notwithstanding the foregoing, any transferee of any
     Transferred Partnership Interest shall be subject to any and all ownership
     limitations (including, without limitation, the Ownership Limit) contained
     in the Charter that may limit or restrict such transferee's ability to
     exercise its Redemption rights, including, without limitation, the
     Ownership Limit. Any transferee, whether or not admitted as a Substituted
     Limited Partner, shall take subject to the obligations of the transferor
     hereunder. Unless admitted as a Substituted Limited Partner, no transferee,
     whether by a voluntary Transfer, by operation of law or otherwise, shall
     have any rights hereunder, other than the rights of an Assignee as provided
     in Section 11.5 hereof.
 
          B. Incapacity. If a Limited Partner is subject to Incapacity, the
     executor, administrator, trustee, committee, guardian, conservator or
     receiver of such Limited Partner's estate shall have all the rights of a
     Limited Partner, but not more rights than those enjoyed by other Limited
     Partners, for the purpose of settling or managing the estate, and such
     power as the Incapacitated Limited Partner possessed to Transfer all or any
     part of its interest in the Partnership. The Incapacity of a Limited
     Partner, in and of itself, shall not dissolve or terminate the Partnership.
 
          C. Opinion of Counsel. In connection with any Transfer of a Limited
     Partner Interest, the General Partner shall have the right to receive an
     opinion of counsel reasonably satisfactory to it to the effect that the
     proposed Transfer may be effected without registration under the Securities
     Act and will not otherwise violate any federal or state securities laws or
     regulations applicable to the Partnership or the Partnership Interests
     Transferred. If, in the opinion of such counsel, such Transfer would
     require the filing of a registration statement under the Securities Act or
     would otherwise violate any federal or state securities laws or regulations
     applicable to the Partnership or the Partnership Units, the General Partner
     may prohibit any Transfer otherwise permitted under this Section 11.3 by a
     Limited Partner of Partnership Interests.
 
          D. Adverse Tax Consequences. No Transfer by a Limited Partner of its
     Partnership Interests (including any Redemption, any other acquisition of
     Partnership Units by the General Partner or any acquisition of Partnership
     Units by the Partnership) may be made to any person if (i) in the opinion
     of legal counsel for the Partnership, it would result in the Partnership
     being treated as an association taxable as a corporation, or (ii) such
     Transfer is effectuated through an "established securities market" or a
     "secondary market (or the substantial equivalent thereof)" within the
     meaning of Code Section 7704.
 
     Section 11.4  Substituted Limited Partners.
 
          A. No Limited Partner shall have the right to substitute a transferee
     (including any Designated Party or other transferees pursuant to Transfers
     permitted by Section 11.3 hereof) as a Limited Partner in its place. A
     transferee (including, but not limited to, any Designated Party) of the
     interest of a Limited
                                      B-44
<PAGE>   265
 
     Partner may be admitted as a Substituted Limited Partner only with the
     Consent of the General Partner, which Consent may be given or withheld by
     the General Partner in its sole and absolute discretion. The failure or
     refusal by the General Partner to permit a transferee of any such interests
     to become a Substituted Limited Partner shall not give rise to any cause of
     action against the Partnership or the General Partner. Subject to the
     foregoing, an Assignee shall not be admitted as a Substituted Limited
     Partner until and unless it furnishes to the General Partner (i) evidence
     of acceptance, in form and substance satisfactory to the General Partner,
     of all the terms, conditions and applicable obligations of this Agreement,
     (ii) a counterpart signature page to this Agreement executed by such
     Assignee and (iii) such other documents and instruments as may be required
     or advisable, in the sole and absolute discretion of the General Partner,
     to effect such Assignee's admission as a Substituted Limited Partner.
 
          B. A transferee who has been admitted as a Substituted Limited Partner
     in accordance with this Article 11 shall have all the rights and powers and
     be subject to all the restrictions and liabilities of a Limited Partner
     under this Agreement.
 
          C. Upon the admission of a Substituted Limited Partner, the General
     Partner shall amend Exhibit A to reflect the name, address and number of
     Partnership Units of such Substituted Limited Partner and to eliminate or
     adjust, if necessary, the name, address and number of Partnership Units of
     the predecessor of such Substituted Limited Partner.
 
     Section 11.5  Assignees. If the General Partner, in its sole and absolute
discretion, does not consent to the admission of any permitted transferee under
Section 11.3 hereof as a Substituted Limited Partner, as described in Section
11.4 hereof, such transferee shall be considered an Assignee for purposes of
this Agreement. An Assignee shall be entitled to all the rights of an assignee
of a limited partnership interest under the Act, including the right to receive
distributions from the Partnership and the share of Net Income, Net Losses and
other items of income, gain, loss, deduction and credit of the Partnership
attributable to the Partnership Units assigned to such transferee and the rights
to Transfer the Partnership Units provided in this Article 11, but shall not be
deemed to be a holder of Partnership Units for any other purpose under this
Agreement (other than as expressly provided in Section 8.6 hereof with respect
to a Qualifying Party that becomes a Tendering Party), and shall not be entitled
to effect a Consent or vote with respect to such Partnership Units on any matter
presented to the Limited Partners for approval (such right to Consent or vote,
to the extent provided in this Agreement or under the Act, fully remaining with
the transferor Limited Partner). In the event that any such transferee desires
to make a further assignment of any such Partnership Units, such transferee
shall be subject to all the provisions of this Article 11 to the same extent and
in the same manner as any Limited Partner desiring to make an assignment of
Partnership Units.
 
     Section 11.6  General Provisions.
 
          A. No Limited Partner may withdraw from the Partnership other than as
     a result of a permitted Transfer of all of such Limited Partner's
     Partnership Units in accordance with this Article 11, with respect to which
     the transferee becomes a Substituted Limited Partner, or pursuant to a
     redemption (or acquisition by the Previous General Partner) of all of its
     Partnership Units pursuant to a Redemption under Section 8.6 hereof and/or
     pursuant to any Partnership Unit Designation.
 
          B. Any Limited Partner who shall Transfer all of its Partnership Units
     in a Transfer (i) permitted pursuant to this Article 11 where such
     transferee was admitted as a Substituted Limited Partner, (ii) pursuant to
     the exercise of its rights to effect a redemption of all of its Partnership
     Units pursuant to a Redemption under Section 8.6 hereof and/or pursuant to
     any Partnership Unit Designation or (iii) to the Previous General Partner
     or the General Partner, whether or not pursuant to Section 8.6.B hereof,
     shall cease to be a Limited Partner.
 
          C. If any Partnership Unit is Transferred in compliance with the
     provisions of this Article 11, or is redeemed by the Partnership, or
     acquired by the Previous General Partner pursuant to Section 8.6 hereof, on
     any day other than the first day of a Fiscal Year, then Net Income, Net
     Losses, each item thereof and all other items of income, gain, loss,
     deduction and credit attributable to such Partnership Unit for such Fiscal
     Year shall be allocated to the transferor Partner or the Tendering Party,
     as the case may be, and, in
                                      B-45
<PAGE>   266
 
     the case of a Transfer or assignment other than a Redemption, to the
     transferee Partner (including, without limitation, the General Partner and
     the Special Limited Partner as transferees of the Previous General Partner
     in the case of an acquisition of Partnership Common Units pursuant to
     Section 8.6 hereof), by taking into account their varying interests during
     the Fiscal Year in accordance with Code Section 706(d), using the "interim
     closing of the books" method or another permissible method selected by the
     General Partner. Solely for purposes of making such allocations, each of
     such items for the calendar month in which a Transfer occurs shall be
     allocated to the transferee Partner and none of such items for the calendar
     month in which a Transfer or a Redemption occurs shall be allocated to the
     transferor Partner or the Tendering Party, as the case may be, if such
     Transfer occurs on or before the fifteenth (15th) day of the month,
     otherwise such items shall be allocated to the transferor. All
     distributions of Available Cash attributable to such Partnership Unit with
     respect to which the Partnership Record Date is before the date of such
     Transfer, assignment or Redemption shall be made to the transferor Partner
     or the Tendering Party, as the case may be, and, in the case of a Transfer
     other than a Redemption, all distributions of Available Cash thereafter
     attributable to such Partnership Unit shall be made to the transferee
     Partner.
 
          D. In addition to any other restrictions on Transfer herein contained,
     in no event may any Transfer or assignment of a Partnership Interest by any
     Partner (including any Redemption, any acquisition of Partnership Units by
     the Previous General Partner or any other acquisition of Partnership Units
     by the Partnership) be made (i) to any person or entity who lacks the legal
     right, power or capacity to own a Partnership Interest; (ii) in violation
     of applicable law; (iii) of any component portion of a Partnership
     Interest, such as the Capital Account, or rights to distributions, separate
     and apart from all other components of a Partnership Interest; (iv) in the
     event that such Transfer would cause either (a) the Previous General
     Partner to cease to comply with the REIT Requirements or (b) the General
     Partner or the Special Limited Partner to cease to qualify as a "qualified
     REIT subsidiary" (within the meaning of Code Section 856(i)(2); (v) if such
     Transfer would, in the opinion of counsel to the Partnership or the General
     Partner, cause a termination of the Partnership for federal or state income
     tax purposes (except as a result of the Redemption (or acquisition by the
     Previous General Partner) of all Partnership Common Units held by all
     Limited Partners other than the Special Limited Partner); (vi) if such
     Transfer would, in the opinion of legal counsel to the Partnership, cause
     the Partnership to cease to be classified as a partnership for federal
     income tax purposes (except as a result of the Redemption (or acquisition
     by the Previous General Partner) of all Partnership Common Units held by
     all Limited Partners other than the Special Limited Partner); (vii) if such
     Transfer would cause the Partnership to become, with respect to any
     employee benefit plan subject to Title I of ERISA, a "party-in-interest"
     (as defined in ERISA Section 3(14)) or a "disqualified person" (as defined
     in Code Section 4975(c)); (viii) if such Transfer would, in the opinion of
     legal counsel to the Partnership, cause any portion of the assets of the
     Partnership to constitute assets of any employee benefit plan pursuant to
     Department of Labor Regulations Section 2510.2-101; (ix) if such Transfer
     requires the registration of such Partnership Interest pursuant to any
     applicable federal or state securities laws; (x) if such Transfer causes
     the Partnership to become a "publicly traded partnership," as such term is
     defined in Code Section 469(k)(2) or Code 7704(b); (xi) if such Transfer
     would cause the Partnership to have more than five hundred (500) partners
     (including as partners those persons indirectly owning an interest in the
     Partnership through a partnership, limited liability company, subchapter S
     corporation or grantor trust); (xii) if such Transfer causes the
     Partnership (as opposed to the Previous General Partner or the General
     Partner) to become a reporting company under the Exchange Act; or (xiii) if
     such Transfer subjects the Partnership to regulation under the Investment
     Company Act of 1940, the Investment Advisors Act of 1940 or ERISA, each as
     amended.

     Section 12.1  Admission of Successor General Partner. A successor to all of
the General Partner's General Partner Interest pursuant to Section 11.2 hereof
who is proposed to be admitted as a successor General Partner shall be admitted
to the Partnership as the General Partner, effective immediately prior to such
Transfer. Any such successor shall carry on the business of the Partnership
without dissolution. In each case, the admission shall be subject to the
successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission.
 
     Section 12.2  Admission of Additional Limited Partners.
 
          A. After the admission to the Partnership of an Original Limited
     Partner on the date hereof, a Person (other than an existing Partner) who
     makes a Capital Contribution to the Partnership in accordance with this
     Agreement shall be admitted to the Partnership as an Additional Limited
     Partner only upon furnishing to the General Partner (i) evidence of
     acceptance, in form and substance satisfactory to the General Partner, of
     all of the terms and conditions of this Agreement, including, without
     limitation, the power of attorney granted in Section 2.4 hereof, (ii) a
     counterpart signature page to this Agreement executed by such Person and
     (iii) such other documents or instruments as may be required in the sole
     and absolute discretion of the General Partner in order to effect such
     Person's admission as an Additional Limited Partner.
 
          B. Notwithstanding anything to the contrary in this Section 12.2, no
     Person shall be admitted as an Additional Limited Partner without the
     consent of the General Partner, which consent may be given or withheld in
     the General Partner's sole and absolute discretion. The admission of any
     Person as an Additional Limited Partner shall become effective on the date
     upon which the name of such Person is recorded on the books and records of
     the Partnership, following the consent of the General Partner to such
     admission.
 
          C. If any Additional Limited Partner is admitted to the Partnership on
     any day other than the first day of a Fiscal Year, then Net Income, Net
     Losses, each item thereof and all other items of income, gain, loss,
     deduction and credit allocable among Partners and Assignees for such Fiscal
     Year shall be allocated among such Additional Limited Partner and all other
     Partners and Assignees by taking into account their varying interests
     during the Fiscal Year in accordance with Code Section 706(d), using the
     "interim closing of the books" method or another permissible method
     selected by the General Partner. Solely for purposes of making such
     allocations, each of such items for the calendar month in which an
     admission of any Additional Limited Partner occurs shall be allocated among
     all the Partners and Assignees including such Additional Limited Partner,
     in accordance with the principles described in Section 11.6.C hereof. All
     distributions of Available Cash with respect to which the Partnership
     Record Date is before the date of such admission shall be made solely to
     Partners and Assignees other than the Additional Limited Partner, and all
     distributions of Available Cash thereafter shall be made to all the
     Partners and Assignees including such Additional Limited Partner.
 
     Section 12.3  Amendment of Agreement and Certificate of Limited
Partnership. For the admission to the Partnership of any Partner, the General
Partner shall take all steps necessary and appropriate under the Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement (including an amendment of Exhibit A)
and, if required by law, shall prepare and file an amendment to the Certificate
and may for this purpose exercise the power of attorney granted pursuant to
Section 2.4 hereof.

     Section 12.5  Limit on Number of Partners. No Person shall be admitted to
the Partnership as an Additional Limited Partner if the effect of such admission
would be to cause the Partnership to have a number of Partners (including as
Partners for this purpose those Persons indirectly owning an interest in the
Partnership through another partnership, a limited liability company, a
subchapter S corporation or a grantor trust) that would cause the Partnership to
become a reporting company under the Exchange Act.

                    DISSOLUTION, LIQUIDATION AND TERMINATION
 
     Section 13.1  Dissolution. The Partnership shall not be dissolved by the
admission of Substituted Limited Partners or Additional Limited Partners or by
the admission of a successor General Partner in accordance with the terms of
this Agreement. Upon the withdrawal of the General Partner, any successor
General Partner shall continue the business of the Partnership without
dissolution. However, the Partnership shall dissolve, and its affairs shall be
wound up, upon the first to occur of any of the following (each a "Liquidating
Event"):
 
          A. the expiration of its term as provided in Section 2.5 hereof;
 
          B. an event of withdrawal, as defined in the Act (including, without
     limitation, bankruptcy), of the sole General Partner unless, within ninety
     (90) days after the withdrawal, a "majority in interest" (as such phrase is
     used in Section 17-801(3) of the Act) of the remaining Partners agree in
     writing, in their sole and absolute discretion, to continue the business of
     the Partnership and to the appointment, effective as of the date of
     withdrawal, of a successor General Partner;

     in its sole and absolute discretion, with or without the Consent of the
     Limited Partners;

     pursuant to the provisions of the Act;
 
          E. the occurrence of a Terminating Capital Transaction;
 
          F. the Redemption (or acquisition by the Previous General Partner, the

     Common Units other than Partnership Common Units held by the General
     Partner or the Special Limited Partner; or

     Section 13.2  Winding Up.
 
          A. Upon the occurrence of a Liquidating Event, the Partnership shall
     continue solely for the purposes of winding up its affairs in an orderly
     manner, liquidating its assets and satisfying the claims of its creditors
     and Partners. After the occurrence of a Liquidating Event, no Partner shall
     take any action that is inconsistent with, or not necessary to or
     appropriate for, the winding up of the Partnership's business and affairs.
     The General Partner (or, in the event that there is no remaining General
     Partner or the General Partner has dissolved, become bankrupt within the
     meaning of the Act or ceased to operate, any Person elected by a Majority
     in Interest of the Limited Partners (the General Partner or such other
     Person being referred to herein as the "Liquidator")) shall be responsible
     for overseeing the winding up and dissolution of the Partnership and shall
     take full account of the Partnership's liabilities and property, and the
     Partnership property shall be liquidated as promptly as is consistent with
     obtaining the fair value thereof, and the proceeds therefrom (which may, to
     the extent determined by the General Partner, include shares of stock in
     the Previous General Partner) shall be applied and distributed in the
     following order:
 
             (1) First, to the satisfaction of all of the Partnership's debts
        and liabilities to creditors other than the Partners and their Assignees
        (whether by payment or the making of reasonable provision for payment
        thereof);

<PAGE>   269
 
             (2) Second, to the satisfaction of all of the Partnership's debts

        of reasonable provision for payment thereof), including, but not limited
        to, amounts due as reimbursements under Section 7.4 hereof;
 
             (3) Third, to the satisfaction of all of the Partnership's debts
        and liabilities to the other Partners and any Assignees (whether by
        payment or the making of reasonable provision for payment thereof); and
 
             (4) Subject to the terms of any Partnership Unit Designation, the
        balance, if any, to the General Partner, the Limited Partners and any
        Assignees in accordance with and in proportion to their positive Capital
        Account balances, after giving effect to all contributions,
        distributions and allocations for all periods.
 
     The General Partner shall not receive any additional compensation for any
     services performed pursuant to this Article 13.
 
          B. Notwithstanding the provisions of Section 13.2.A hereof that
     require liquidation of the assets of the Partnership, but subject to the
     order of priorities set forth therein, if prior to or upon dissolution of
     the Partnership the Liquidator determines that an immediate sale of part or
     all of the Partnership's assets would be impractical or would cause undue
     loss to the Partners, the Liquidator may, in its sole and absolute
     discretion, defer for a reasonable time the liquidation of any assets
     except those necessary to satisfy liabilities of the Partnership (including
     to those Partners as creditors) and/or distribute to the Partners, in lieu
     of cash, as tenants in common and in accordance with the provisions of
     Section 13.2.A hereof, undivided interests in such Partnership assets as
     the Liquidator deems not suitable for liquidation. Any such distributions
     in kind shall be made only if, in the good faith judgment of the
     Liquidator, such distributions in kind are in the best interest of the
     Partners, and shall be subject to such conditions relating to the
     disposition and management of such properties as the Liquidator deems
     reasonable and equitable and to any agreements governing the operation of
     such properties at such time. The Liquidator shall determine the fair
     market value of any property distributed in kind using such reasonable
     method of valuation as it may adopt.
 
          C. In the event that the Partnership is "liquidated" within the
     meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be
     made pursuant to this Article 13 to the Partners and Assignees that have
     positive Capital Accounts in compliance with Regulations Section
     1.704-1(b)(2)(ii)(b)(2) to the extent of, and in proportion to, positive
     Capital Account balances. If any Partner has a deficit balance in its
     Capital Account (after giving effect to all contributions, distributions
     and allocations for all taxable years, including the year during which such
     liquidation occurs), such Partner shall have no obligation to make any
     contribution to the capital of the Partnership with respect to such
     deficit, and such deficit shall not be considered a debt owed to the
     Partnership or to any other Person for any purpose whatsoever. In the sole
     and absolute discretion of the General Partner or the Liquidator, a pro
     rata portion of the distributions that would otherwise be made to the
     Partners pursuant to this Article 13 may be withheld or escrowed to provide
     a reasonable reserve for Partnership liabilities (contingent or otherwise)
     and to reflect the unrealized portion of any installment obligations owed
     to the Partnership, provided that such withheld or escrowed amounts shall
     be distributed to the General Partner and Limited Partners in the manner
     and order of priority set forth in Section 13.2.A hereof as soon as
     practicable.
 
     Section 13.3  Deemed Distribution and Recontribution. Notwithstanding any
other provision of this Article 13, in the event that the Partnership is
liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), but
no Liquidating Event has occurred, the Partnership's Property shall not be
liquidated, the Partnership's liabilities shall not be paid or discharged and
the Partnership's affairs shall not be wound up. Instead, for federal income tax
purposes the Partnership shall be deemed to have distributed the Property in
kind to the Partners and the Assignees, who shall be deemed to have assumed and
taken such Property subject to all Partnership liabilities, all in accordance
with their respective Capital Accounts. Immediately thereafter, the Partners and
the Assignees shall be deemed to have recontributed the Partnership
                                      B-49
<PAGE>   270
 
Property in kind to the Partnership, which shall be deemed to have assumed and
taken such Property subject to all such liabilities; provided, however, that
nothing in this Section 13.3 shall be deemed to have constituted any Assignee as
a Substituted Limited Partner without compliance with the provisions of Section
11.4 hereof.
 
     Section 13.4  Rights of Limited Partners. Except as otherwise provided in
this Agreement, (a) each Limited Partner shall look solely to the assets of the
Partnership for the return of its Capital Contribution, (b) no Limited Partner
shall have the right or power to demand or receive property other than cash from
the Partnership and (c) no Limited Partner shall have priority over any other
Limited Partner as to the return of its Capital Contributions, distributions or
allocations.
 
     Section 13.5  Notice of Dissolution. In the event that a Liquidating Event
occurs or an event occurs that would, but for an election or objection by one or
more Partners pursuant to Section 13.1 hereof, result in a dissolution of the
Partnership, the General Partner shall, within thirty (30) days thereafter,
provide written notice thereof to each of the Partners and, in the General
Partner's sole and absolute discretion or as required by the Act, to all other
parties with whom the Partnership regularly conducts business (as determined in
the sole and absolute discretion of the General Partner), and the General
Partner may, or, if required by the Act, shall, publish notice thereof in a
newspaper of general circulation in each place in which the Partnership
regularly conducts business (as determined in the sole and absolute discretion
of the General Partner).
 
     Section 13.6  Cancellation of Certificate of Limited Partnership. Upon the
completion of the liquidation of the Partnership cash and property as provided
in Section 13.2 hereof, the Partnership shall be terminated, a certificate of
cancellation shall be filed with the State of Delaware, all qualifications of
the Partnership as a foreign limited partnership or association in jurisdictions
other than the State of Delaware shall be cancelled, and such other actions as
may be necessary to terminate the Partnership shall be taken.
 
     Section 13.7  Reasonable Time for Winding-Up. A reasonable time shall be
allowed for the orderly winding-up of the business and affairs of the
Partnership and the liquidation of its assets pursuant to Section 13.2 hereof,
in order to minimize any losses otherwise attendant upon such winding-up, and
the provisions of this Agreement shall remain in effect between the Partners
during the period of liquidation.

     PROCEDURES FOR ACTIONS AND CONSENTS OF PARTNERS; AMENDMENTS; MEETINGS
 
     Section 14.1  Procedures for Actions and Consents of Partners. The actions
requiring consent or approval of Limited Partners pursuant to this Agreement,
including Section 7.3 hereof, or otherwise pursuant to applicable law, are
subject to the procedures set forth in this Article 14.
 
     Section 14.2  Amendments. Amendments to this Agreement may be proposed by
the General Partner or by a Majority in Interest of the Limited Partners.
Following such proposal, the General Partner shall submit any proposed amendment
to the Limited Partners. The General Partner shall seek the written consent of
the Limited Partners on the proposed amendment or shall call a meeting to vote
thereon and to transact any other business that the General Partner may deem
appropriate. For purposes of obtaining a written consent, the General Partner
may require a response within a reasonable specified time, but not less than
fifteen (15) days, and failure to respond in such time period shall constitute a
consent that is consistent with the General Partner's recommendation with
respect to the proposal; provided, however, that an action shall become
effective at such time as requisite consents are received even if prior to such
specified time.
 
   
     Section 14.3  Meetings of the Partners.
    
 
          A. Meetings of the Partners may be called by the General Partner and
     shall be called upon the receipt by the General Partner of a written
     request by a Majority in Interest of the Limited Partners. The call shall
     state the nature of the business to be transacted. Notice of any such
     meeting shall be given to all Partners not less than seven (7) days nor
     more than thirty (30) days prior to the date of such meeting. Partners may
     vote in person or by proxy at such meeting. Whenever the vote or Consent of
     Partners is permitted or required under this Agreement, such vote or
     Consent may be given at a meeting of Partners or may be given in accordance
     with the procedure prescribed in Section 14.3.B hereof.
                                      B-50
<PAGE>   271
 
          B. Any action required or permitted to be taken at a meeting of the
     Partners may be taken without a meeting if a written consent setting forth
     the action so taken is signed by a majority of the Percentage Interests of
     the Partners (or such other percentage as is expressly required by this
     Agreement for the action in question). Such consent may be in one
     instrument or in several instruments, and shall have the same force and
     effect as a vote of a majority of the Percentage Interests of the Partners
     (or such other percentage as is expressly required by this Agreement). Such
     consent shall be filed with the General Partner. An action so taken shall
     be deemed to have been taken at a meeting held on the effective date so
     certified.
 
          C. Each Limited Partner may authorize any Person or Persons to act for
     it by proxy on all matters in which a Limited Partner is entitled to
     participate, including waiving notice of any meeting, or voting or
     participating at a meeting. Every proxy must be signed by the Limited
     Partner or its attorney-in-fact. No proxy shall be valid after the
     expiration of eleven (11) months from the date thereof unless otherwise
     provided in the proxy (or there is receipt of a proxy authorizing a later
     date). Every proxy shall be revocable at the pleasure of the Limited
     Partner executing it, such revocation to be effective upon the
     Partnership's receipt of written notice of such revocation from the Limited
     Partner executing such proxy.
 
          D. Each meeting of Partners shall be conducted by the General Partner
     or such other Person as the General Partner may appoint pursuant to such
     rules for the conduct of the meeting as the General Partner or such other
     Person deems appropriate in its sole and absolute discretion. Without
     limitation, meetings of Partners may be conducted in the same manner as
     meetings of the General Partner's shareholders and may be held at the same
     time as, and as part of, the meetings of the General Partner's
     shareholders.

                               GENERAL PROVISIONS
 
     Section 15.1  Addresses and Notice. Any notice, demand, request or report
required or permitted to be given or made to a Partner or Assignee under this
Agreement shall be in writing and shall be deemed given or made when delivered
in person or when sent by first class United States mail or by other means of
written communication (including by telecopy, facsimile, or commercial courier
service) to the Partner or Assignee at the address set forth in Exhibit A or
such other address of which the Partner shall notify the General Partner in
writing.
 
     Section 15.2  Titles and Captions. All article or section titles or
captions in this Agreement are for convenience only. They shall not be deemed
part of this Agreement and in no way define, limit, extend or describe the scope
or intent of any provisions hereof. Except as specifically provided otherwise,
references to "Articles" or "Sections" are to Articles and Sections of this
Agreement.
 
     Section 15.3  Pronouns and Plurals. Whenever the context may require, any
pronouns used in this Agreement shall include the corresponding masculine,
feminine or neuter forms, and the singular form of nouns, pronouns and verbs
shall include the plural and vice versa.
 
     Section 15.4  Further Action. The parties shall execute and deliver all
documents, provide all information and take or refrain from taking action as may
be necessary or appropriate to achieve the purposes of this Agreement.
 
     Section 15.5  Binding Effect. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their heirs, executors,
administrators, successors, legal representatives and permitted assigns.
 
     Section 15.6  Waiver.
 
          A. No failure by any party to insist upon the strict performance of
     any covenant, duty, agreement or condition of this Agreement or to exercise
     any right or remedy consequent upon a breach thereof shall constitute
     waiver of any such breach or any other covenant, duty, agreement or
     condition.

<PAGE>   272
 
          B. The restrictions, conditions and other limitations on the rights
     and benefits of the Limited Partners contained in this Agreement, and the
     duties, covenants and other requirements of performance or notice by the
     Limited Partners, are for the benefit of the Partnership and, except for an
     obligation to pay money to the Partnership, may be waived or relinquished
     by the General Partner, in its sole and absolute discretion, on behalf of
     the Partnership in one or more instances from time to time and at any time;
     provided, however, that any such waiver or relinquishment may not be made
     if it would have the effect of (i) creating liability for any other Limited
     Partner, (ii) causing the Partnership to cease to qualify as a limited
     partnership, (iii) reducing the amount of cash otherwise distributable to
     the Limited Partners, (iv) resulting in the classification of the
     Partnership as an association or publicly traded partnership taxable as a
     corporation or (v) violating the Securities Act, the Exchange Act or any
     state "blue sky" or other securities laws; provided, further, that any
     waiver relating to compliance with the Ownership Limit or other
     restrictions in the Charter shall be made and shall be effective only as
     provided in the Charter.
 
     Section 15.7  Counterparts. This Agreement may be executed in counterparts,
all of which together shall constitute one agreement binding on all the parties
hereto, notwithstanding that all such parties are not signatories to the
original or the same counterpart. Each party shall become bound by this
Agreement immediately upon affixing its signature hereto.
 
     Section 15.8  Applicable Law. This Agreement shall be construed and
enforced in accordance with and governed by the laws of the State of Delaware,
without regard to the principles of conflicts of law. In the event of a conflict
between any provision of this Agreement and any non-mandatory provision of the
Act, the provisions of this Agreement shall control and take precedence.
 
     Section 15.9  Entire Agreement. This Agreement contains all of the
understandings and agreements between and among the Partners with respect to the
subject matter of this Agreement and the rights, interests and obligations of
the Partners with respect to the Partnership.
 
     Section 15.10  Invalidity of Provisions. If any provision of this Agreement
is or becomes invalid, illegal or unenforceable in any respect, the validity,
legality and enforceability of the remaining provisions contained herein shall
not be affected thereby.
 
     Section 15.11  Limitation to Preserve REIT Status. Notwithstanding anything
else in this Agreement, to the extent that the amount paid, credited,
distributed or reimbursed by the Partnership to any REIT Partner or its
officers, directors, employees or agents, whether as a reimbursement, fee,
expense or indemnity (a "REIT Payment"), would constitute gross income to the
REIT Partner for purposes of Code Section 856(c)(2) or Code Section 856(c)(3),
then, notwithstanding any other provision of this Agreement, the amount of such
REIT Payments, as selected by the General Partner in its discretion from among
items of potential distribution, reimbursement, fees, expenses and indemnities,
shall be reduced for any Fiscal Year so that the REIT Payments, as so reduced,
for or with respect to such REIT Partner shall not exceed the lesser of:
 
          (i) an amount equal to the excess, if any, of (a) four and nine-tenths
     percent (4.9%) of the REIT Partner's total gross income (but excluding the
     amount of any REIT Payments) for the Fiscal Year that is described in
     subsections (A) through (H) of Code Section 856(c)(2) over (b) the amount
     of gross income (within the meaning of Code Section 856(c)(2)) derived by
     the REIT Partner from sources other than those described in subsections (A)
     through (H) of Code Section 856(c)(2) (but not including the amount of any
     REIT Payments); or
 
          (ii) an amount equal to the excess, if any, of (a) twenty-four percent
     (24%) of the REIT Partner's total gross income (but excluding the amount of
     any REIT Payments) for the Fiscal Year that is described in subsections (A)
     through (I) of Code Section 856(c)(3) over (b) the amount of gross income
     (within the meaning of Code Section 856(c)(3)) derived by the REIT Partner
     from sources other than those described in subsections (A) through (I) of
     Code Section 856(c)(3) (but not including the amount of any REIT Payments);
 
                                      B-52
<PAGE>   273
 
provided, however, that REIT Payments in excess of the amounts set forth in
clauses (i) and (ii) above may be made if the General Partner, as a condition
precedent, obtains an opinion of tax counsel that the receipt of such excess
amounts shall not adversely affect the REIT Partner's ability to qualify as a
REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a
consequence of the limitations set forth in this Section 15.11, such REIT
Payments shall carry over and shall be treated as arising in the following
Fiscal Year. The purpose of the limitations contained in this Section 15.11 is
to prevent any REIT Partner from failing to qualify as a REIT under the Code by
reason of such REIT Partner's share of items, including distributions,
reimbursements, fees, expenses or indemnities, receivable directly or indirectly
from the Partnership, and this Section 15.11 shall be interpreted and applied to
effectuate such purpose.
 
     Section 15.12  No Partition. No Partner nor any successor-in-interest to a
Partner shall have the right while this Agreement remains in effect to have any
property of the Partnership partitioned, or to file a complaint or institute any
proceeding at law or in equity to have such property of the Partnership
partitioned, and each Partner, on behalf of itself and its successors and
assigns hereby waives any such right. It is the intention of the Partners that
the rights of the parties hereto and their successors-in-interest to Partnership
property, as among themselves, shall be governed by the terms of this Agreement,
and that the rights of the Partners and their successors-in-interest shall be
subject to the limitations and restrictions as set forth in this Agreement.
 
     Section 15.13  No Third-Party Rights Created Hereby. The provisions of this
Agreement are solely for the purpose of defining the interests of the Partners,
inter se; and no other person, firm or entity (i.e., a party who is not a
signatory hereto or a permitted successor to such signatory hereto) shall have
any right, power, title or interest by way of subrogation or otherwise, in and
to the rights, powers, title and provisions of this Agreement. No creditor or
other third party having dealings with the Partnership shall have the right to
enforce the right or obligation of any Partner to make Capital Contributions or
loans to the Partnership or to pursue any other right or remedy hereunder or at
law or in equity. None of the rights or obligations of the Partners herein set
forth to make Capital Contributions or loans to the Partnership shall be deemed
an asset of the Partnership for any purpose by any creditor or other third
party, nor may any such rights or obligations be sold, transferred or assigned
by the Partnership or pledged or encumbered by the Partnership to secure any
debt or other obligation of the Partnership or any of the Partners.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
AIMCO
 
     AIMCO's Charter limits the liability of AIMCO's directors and officers to
AIMCO and its stockholders to the fullest extent permitted from time to time by
Maryland law. Maryland law presently permits the liability of directors and
officers to a corporation or its stockholders for money damages to be limited,
except (i) to the extent that it is proved that the director or officer actually
received an improper benefit or profit in money, property or services for the
amount of the benefit or profit in money, property or services actually
received, or (ii) if a judgment or other final adjudication is entered in a
proceeding based on a finding that the director's or officer's action, or
failure to act, was the result of active and deliberate dishonesty and was
material to the cause of action adjudicated in the proceeding. This provision
does not limit the ability of AIMCO or its stockholders to obtain other relief,
such as an injunction or rescission.
 
     AIMCO's Charter and Bylaws require AIMCO to indemnify its directors,
officers and certain other parties to the fullest extent permitted from time to
time by Maryland law. The MGCL permits a corporation to indemnify its directors,
officers and certain other parties against judgments, penalties, fines,
settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made a party by reason of their service to
or at the request of the corporation, unless it is established that (i) the act
or omission of the indemnified party was material to the matter giving rise to
the proceeding and (x) was committed in bad faith or (y) was the result of
active and deliberate dishonesty, (ii) the indemnified party actually received
an improper personal benefit in money, property or services or (iii) in the case
of any criminal proceeding, the indemnified party had reasonable cause to
believe that the act or omission was unlawful. Indemnification may be made
against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by the director or officer in connection with the proceeding;
provided, however, that if the proceeding is one by or in the right of the
corporation, indemnification may not be made with respect to any proceeding in
which the director or officer has been adjudged to be liable to the corporation.
In addition, a director or officer may not be indemnified with respect to any
proceeding charging improper personal benefit to the director or officer in
which the director or officer was adjudged to be liable on the basis that
personal benefit was improperly received. The termination of any proceeding by
conviction, or upon a plea of nolo contendere or its equivalent, or an entry of
any order of probation prior to judgment, creates a rebuttable presumption that
the director or officer did not meet the requisite standard of conduct required
for indemnification to be permitted. It is the position of the Commission that
indemnification of directors and officers for liabilities arising under the
Securities Act is against public policy and is unenforceable pursuant to Section
14 of the Securities Act.
 
     AIMCO has entered into agreements with certain of its officers, pursuant to
which AIMCO has agreed to indemnify such officers to the fullest extent
permitted by applicable law.
 
THE AIMCO OPERATING PARTNERSHIP
 
     The AIMCO Operating Partnership Agreement requires the AIMCO Operating
Partnership to indemnify its directors and officers (each an "Indemnitee") to
the fullest extent authorized by applicable law against any and all losses,
claims, damages, liabilities, joint or several, expenses (including, without
limitation, attorney's fees and other legal fees and expenses), judgments,
fines, settlements and other amounts arising from any and all claims, demands,
actions, suits or proceedings, civil, criminal, administrative or investigative,
that relate to the operations of the AIMCO Operating Partnership. Such
indemnification continues after the Indemnitee ceases to be a director or
officer. The right to indemnification includes the right to be paid by the AIMCO
Operating Partnership the expenses incurred in defending any proceeding in
advance of its final disposition upon the delivery of an undertaking by or on
behalf of the Indemnitee to repay all amounts
 
                                      II-1

advanced if a final judicial decision is rendered that such Indemnitee did not
meet the standard of conduct permitting indemnification under the AIMCO
Operating Partnership Agreement or applicable law.
 
     The Partnership maintains insurance, at its expense, to protect against any
liability or loss, regardless of whether any director or officer is entitled to
indemnification under the AIMCO Operating Partnership Agreement or applicable
law.

ITEM 22. UNDERTAKINGS.
 
     (a) The undersigned registrants hereby undertake:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933, as amended;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, as amended, each such post-effective amendment
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of the registrants' annual reports pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be permitted to directors, officers and controlling
persons of the registrants pursuant to the foregoing provisions, or otherwise,
the registrants have been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrants of expenses incurred
or paid by a director, officer or controlling person of the registrants in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrants will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
     (d) The undersigned registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other
 
                                      II-3
<PAGE>   279
 
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
   
     (e) The undersigned registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
    
 
   
     (f) The undersigned registrants hereby undertake to not issue securities
under this registration statement in order to effect any "roll-up transaction"
(as such term in defined in paragraph (c) of Item 901 of Regulation S-K).
Furthermore, the undersigned registrants hereby undertake to supply by means of
a post-effective amendment all information concerning an offer to purchase
partnership interests in exchange for securities issued under this registration
statement, prior to commencing such an offer, if pursuant to the provisions of
subparagraph (iv), (vii) or (viii) of paragraph (c)(2) of Item 901 of Regulation
S-K, such offer fails to constitute a roll-up transaction.
