                           OFFER TO PURCHASE FOR CASH
                                      AIMCO
                             AIMCO PROPERTIES, L.P.
  is offering to purchase any and all units of limited partnership interest in
                           WINTHROP GROWTH INVESTORS 1
                               LIMITED PARTNERSHIP
                          FOR $496.00 PER UNIT IN CASH

Upon the terms and subject to the conditions set forth herein, we will accept
any and all units validly tendered in response to our offer. If units are
validly tendered and not properly withdrawn prior to the expiration date and the
purchase of all such units would result in there being less than 320
unitholders, we will purchase only 99% of the total number of units so tendered
by each limited partner.

Our offer and your withdrawal rights will expire at 5:00 P.M., New York City
time, on June 13, 2000, unless we extend the deadline.

You will not pay any partnership transfer fees if you tender your units. You
will pay any other fees and costs, including any transfer taxes.

Our offer is not subject to a minimum number of units being tendered.

Our offer price will be reduced for any distributions subsequently made by your
partnership prior to the expiration of our offer.


         SEE "RISK FACTORS" BEGINNING ON PAGE 4 OF THIS OFFER TO PURCHASE FOR A
DESCRIPTION OF RISK FACTORS THAT YOU SHOULD CONSIDER IN CONNECTION WITH OUR
OFFER, INCLUDING THE FOLLOWING:

         o        We determined the offer price of $496.00 per unit without any
                  arms-length negotiations. Accordingly, our offer price may not
                  reflect the fair market value of your units.

         o        Your general partner and the property manager of the
                  residential properties are subsidiaries of ours and,
                  therefore, the general partner has substantial conflicts of
                  interest with respect to our offer.

         o        We are making this offer with a view to making a profit and,
                  therefore, there is a conflict between our desire to purchase
                  your units at a low price and your desire to sell your units
                  at a high price.

                                                        (Continued on next page)

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

         If you desire to accept our offer, you should complete and sign the
enclosed Acknowledgment and Agreement as instructed in the letter of transmittal
attached as Annex II hereto (collectively the "the letter of transmittal"). The
signed yellow letter of transmittal and any other required documents must be
mailed or delivered to River Oaks Partnership Services, Inc., which is acting as
Information Agent in connection with our offer, at one of its addresses set
forth on the back cover of this offer to purchase. It is only necessary to
return the acknowledgment and agreement part of the letter of transmittal.
QUESTIONS AND REQUESTS FOR ASSISTANCE OR FOR ADDITIONAL COPIES OF THIS OFFER TO
PURCHASE OR THE LETTER OF TRANSMITTAL MAY ALSO BE DIRECTED TO THE INFORMATION
AGENT AT (888) 349-2005.

                                                     (continued from cover page)

         o        Continuation of your partnership will result in our affiliates
                  continuing to receive management fees from your partnership.
                  Such fees would not be payable if your partnership was
                  liquidated.

         o        It is possible that we may conduct a future offer at a higher
                  price.

         o        For any units that we acquire from you, you will not receive
                  any future distributions from operating cash flow of your
                  partnership or upon a sale or refinancing of property owned by
                  your partnership.

         o        If we acquire a substantial number of units, we will increase
                  our ability to influence voting decisions with respect to your
                  partnership and may control such voting decisions, including
                  the removal of the general partner, the addition of a new
                  general partner, most amendments to the partnership agreement
                  and the sale of all or substantially all of your partnership's
                  assets.

                               SUMMARY TERM SHEET

         This summary term sheet highlights the most material information
regarding our offer, but it does not describe all of the details thereof. We
urge you to read this entire offer to purchase which contains the full details
of our offer. We have also included in the summary term sheet references to the
sections of this offer to purchase where a more complete discussion may be
found.

o        THE OFFER. Subject to the terms hereof, we are offering to acquire any
         and all of the limited partnership interests (units) in Winthrop Growth
         Investors 1 Limited Partnership, your partnership for $496.00 per unit
         in cash. See "The Offer--Section 1. Terms of the Offer; Expiration
         Date; Proration" and "The Offer--Section 9. Background and Reasons for
         the Offer--Determination of Offer Price."

o        FACTORS IN DETERMINING THE OFFER PRICE. In determining the offering
         price per unit we considered:

         o        The fact that we believe the per unit liquidation value of
                  your partnership is equal to our offer price per unit.

         o        There is no trading market for the units. See "The
                  Offer--Section 9. Background and Reasons for the
                  Offer--Comparison of Consideration to Alternative
                  Consideration."

o        PRORATIONS. If the purchase of all validly tendered units would result
         in there being less than 320 unitholders, we will purchase only 99% of
         the total number of units so tendered by each limited partner. See "The
         Offer--Section 1. Terms of the Offer; Expiration Date; Proration."

o        EXPIRATION DATE. Our offer expires on June 13, 2000, unless extended,
         and you can tender your units until our offer expires. See "The
         Offer--Section 1. Terms of the Offer; Expiration Date; Proration."

o        RIGHT TO EXTEND THE EXPIRATION DATE. We can extend the offer in our
         sole discretion, and we will send you a notice of any such extension.
         See "The Offer--Section 5. Extension of Tender Period; Termination;
         Amendment; Subsequent Offering Period."

o        HOW TO TENDER. To tender your units, complete the accompanying letter
         of transmittal and send it to the Information Agent, River Oaks
         Partnership, Inc., at one of the address set forth on the back of this
         offer to purchase. See "The Offer--Section 3. Procedures for
         Tendering."

o        WITHDRAWAL RIGHTS. You can withdraw your units at any time prior to the
         expiration of the offer, including any extensions. In addition, you can
         withdraw your units any time on or after July 17, 2000, if we have not
         already accepted units for purchase and payment. See "The
         Offer--Section 4. Withdrawal Rights."

o        HOW TO WITHDRAW. To withdraw your units, you need to send in a notice
         of withdrawal identifying yourself and the units to be withdrawn. See
         "The Offer--Section 4. Withdrawal Rights."

o        TAX CONSEQUENCES. Your sale of units will be a taxable transaction for
         federal income tax purposes, the consequences to each limited partner
         may vary and you should consult your tax advisor on the precise tax
         consequences to you. See "The Offer-Section 6. Certain Federal Income
         Tax Matters."

o        AVAILABILITY OF FUNDS. We currently have the necessary cash and a line
         of credit to consummate the offers. See "The Offer--Section 15. Source
         of Funds."

o        CONDITIONS TO THE OFFER. There are a number of conditions to our offer,
         including having adequate cash on hand and borrowings under a line of
         credit, lack of competing tender offers, lack of certain changes in


<PAGE>   5
                                                                          Page 2


         your partnership, and lack of certain changes in the financial markets.
         See "The Offer--Section 17. Condition to the Offer."

o        REMAINING AS A LIMITED PARTNER. If you do not tender your units, you
         will continue to remain a limited partner in your partnership and we
         have no plans to alter the operations, business or financial position

         Offer--Section 7. Effects of the Offer."

o        WHO WE ARE. We are AIMCO Properties, L.P., the main operating

         "The Offer--Section 13. Certain Information Concerning Your
         Partnership."

o        NO GENERAL PARTNER RECOMMENDATION. The general partner of your
         partnership makes no recommendation as to whether you should tender or
         refrain from tendering your units, and believes each limited partner
         should make his or her own decision whether or not to tender. See
         "Terms of the Offer--Section 10. Position of the General Partner of
         Your Partnership With Respect to the Offer."

o        NO SUBSEQUENT OFFERING PERIOD. We will not have a subsequent offering
         period after the expiration date of the initial offering period
         (including any extensions). See "The Offer--Extension of Tender Period;
         Termination; Amendment; Subsequent Offer Period."

o        ADDITIONAL INFORMATION. For more assistance in tendering your units,

                                  INTRODUCTION

         We are offering to purchase any and all of the outstanding units of
limited partnership interest in your partnership, for the purchase price of
$496.00 per unit, net to the seller in cash, without interest, less the amount
of distributions, if any, made by your partnership in respect of any unit from
the date hereof until the expiration date. Our offer is made upon the terms and
subject to the conditions set forth in this offer to purchase and in the
accompanying letter of transmittal.

         Upon the terms and subject to the conditions set forth herein, we will
accept any and all units validly tendered in response to our offer. If units are
validly tendered prior to the expiration date and not properly withdrawn prior
to the expiration date in accordance with the procedures set forth in "The
Offer--Section 4. Withdrawal Rights" and the purchase of all such units would
result in there being less than 320 unitholders, we will purchase only 99% of
the total number of units so tendered by each limited partner. If we are going
to purchase only 99% of the units validly tendered, we will notify you of such
fact.

         We will pay any transfer fees imposed for the transfer of units by your
partnership. However, you will have to pay any taxes that arise from your sale
of units. You will also have to pay any fees or commissions imposed by your
broker, or by any custodian or other trustee of any Individual Retirement
Account or benefit plan which is the owner of record of your units. Although the
fees charged for transferring units from an Individual Retirement Account vary,
such fees are typically $25-$50 per transaction. Depending on the number of
units that you tender, any fees charged on a per transaction basis could exceed
the aggregate offer price you receive (as a result of proration or otherwise).

         We have retained River Oaks Partnership Services, Inc. to act as the
Information Agent in connection with our offer. We will pay all charges and
expenses in connection with the services of the Information Agent. The offer is
not conditioned on any minimum number of units being tendered. However, certain
other conditions do apply. See "The Offer--Section 17. Conditions of the Offer."
You may tender all or any portion of the units that you own. Under no
circumstances will we be required to accept any unit if the transfer of that
unit to us would be prohibited by the agreement of limited partnership of your
partnership.

         Our offer will expire at 5:00 P.M. New York City time, on June 13,
2000, unless extended. 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. You may withdraw your tender of units
pursuant to the offer at any time prior to the expiration date of our offer and,
if we have not accepted such units for payment, on or after July 17, 2000.

         We are AIMCO Properties, L.P., a Delaware limited partnership. Together
with our subsidiaries, we conduct substantially all of the operations of
Apartment Investment and Management Company, or AIMCO. AIMCO is a
self-administered and self-managed real estate investment trust engaged in the
ownership, acquisition, development, expansion and management of multifamily
apartment properties. As of December 31, 1999, AIMCO owned or controlled, held
an equity interest in or managed 363,462 apartment units in 1,942 properties
located in 49 states, the District of Columbia and Puerto Rico. AIMCO's Class A
Common Stock is listed and traded on the New York Stock Exchange under the
symbol "AIV."

                                                                          Page 4


                                  RISK FACTORS

         Before deciding whether or not to tender any of your units, you should
consider carefully the following risks and disadvantages of the offer:

NO THIRD PARTY VALUATION OR APPRAISAL; NO ARMS-LENGTH NEGOTIATION

         We did not base our valuation of the properties owned by your
partnership on any third-party appraisal or valuation. We established the terms
of our offer without any arms-length negotiation. The terms of the offer could
differ if they were subject to independent third party negotiations. It is
uncertain whether our offer price reflects the value which would be realized
upon a sale of your units to a third party.

NO FAIRNESS OPINION FROM A THIRD PARTY

         We did not obtain an opinion from a third party that our offer price is
fair from a financial point of view.

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. Our offer price does not necessarily reflect the price that you would
receive in an open market for your units. Such prices could be higher than our
offer price.

OFFER PRICE DOES NOT REFLECT FUTURE PROSPECTS

         Our offer price is based on your partnership's historical property
income. It does not ascribe any value to potential future improvements in the
operating performance of your partnership's residential properties.

OFFER PRICE BASED ON OUR ESTIMATE OF LIQUIDATION PROCEEDS

         The offer price represents only our estimate of the amount you would
receive if we liquidated the partnership. In determining the liquidation value,
we used for the residential properties the direct capitalization method to
estimate the value of your partnership's properties because we think a
prospective purchaser of the properties would value the properties using this
method. In doing so, we applied a capitalization rate to your partnership's
property income for the year ended December 31, 1999. If property income for a
different period or a different capitalization rate was used, a higher valuation
could result. Other methods of valuing your units could also result in a higher
valuation.

OFFER PRICE MAY NOT REPRESENT LIQUIDATION VALUE

         The actual proceeds obtained from a liquidation are highly uncertain
and could be more than our estimate. Accordingly, our offer price could be less
than the net proceeds that you would realize upon an actual liquidation of your
partnership.

CONTINUATION OF THE PARTNERSHIP; NO TIME FRAME REGARDING SALE OF PROPERTIES

         Your general partner (which is our subsidiary) is proposing to continue
to operate your partnership and not to attempt to liquidate it at the present
time. It is not known when the properties owned by your partnership may be sold.
There may be no way to liquidate your investment in a partnership in the future
until the residential properties are sold and the partnership is liquidated. The
general partner of your partnership continually considers whether a property
should be sold or otherwise disposed of after consideration of relevant factors,
including prevailing economic conditions, availability of favorable financing
and tax considerations, with a view to achieving maximum capital appreciation
for your partnership. At the current time the general partner of your
partnership believes that a sale of the properties would not be advantageous
given market conditions, the condition of the properties and tax


<PAGE>   8
                                                                          Page 5


considerations. In particular, the general partner considered the changes in the
local rental market, the potential for appreciation in the value of a property
and the tax consequences to you and your partners on a sale of property. We
cannot predict when any property will be sold or otherwise disposed of.

HOLDING UNITS MAY RESULT IN GREATER FUTURE VALUE

         Although a liquidation of your partnership is not currently
contemplated in the near future, you might receive more value if you retain your
units until your partnership is liquidated.

CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER

         The general partner of your partnership is our subsidiary and,
therefore, has substantial conflicts of interest with respect to our offer. We
are making this offer with a view to making a profit. There is a conflict
between our desire to purchase your units at a low price and your desire to sell
your units at a high price. We determined our offer price without negotiation
with any other party, including any general or limited partner.

NO GENERAL PARTNER RECOMMENDATION

         The general partner of your partnership makes no recommendation as to
whether you should tender or refrain from tendering your units. Although the
general partner believes the offer is fair, you must make your own decision
whether or not to participate in the offer, based upon a number of factors,
including several factors that may be personal to you, such as your financial
position, your need or desire for liquidity, your preferences regarding the
timing of when you might wish to sell your units, other financial opportunities
available to you, and your tax position and the tax consequences to you of
selling your units.

CONFLICTS OF INTEREST RELATING TO MANAGEMENT FEES

         Since we or our subsidiaries receive fees for managing your partnership
and its residential properties, a conflict of interest exists between our
continuing the partnership and receiving such fees, and the liquidation of the
partnership and the termination of such fees. Another conflict is 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 residential property
manager of any property owned by your partnership would result in a decrease or
elimination of the substantial fees paid to them for services provided to your
partnership.

POSSIBLE FUTURE OFFER AT A HIGHER PRICE

         It is possible that we may conduct a future offer at a higher price.
Such a decision will depend on, among other things, the performance of the
partnership, prevailing economic conditions, and our interest in acquiring
additional limited partnership interests.

RECOGNITION OF TAXABLE GAIN ON A SALE OF YOUR UNITS

         Your sale of units for cash will be a taxable sale, with the result
that you will recognize taxable gain or loss measured by the difference between
the amount realized on the sale and your adjusted tax basis in the units of
limited partnership interest of your partnership you transfer to us. The "amount
realized" with respect to a unit of limited partnership interest you transfer to
us will be equal to the sum of the amount of cash received by you for the unit
sold pursuant to the offer plus the amount of partnership liabilities allocable
to the unit. The particular tax consequences for you of our offer will depend
upon a number of factors related to your tax situation, including your tax basis
in the units you transfer to us, whether you dispose of all of your units and
whether you have available suspended passive losses, credits or other tax items
to offset any gain recognized as a result of your sale of your units. Therefore,
depending on your basis in the units and your tax position, your taxable gain
and any tax liability resulting from a sale of units to us pursuant to the offer
could exceed our offer price. Because the income tax consequences of tendering
units will not be the same for everyone, you should consult your own tax advisor
to


<PAGE>   9
                                                                          Page 6


determine the tax consequences of the offer to you.

LOSS OF FUTURE DISTRIBUTIONS FROM YOUR PARTNERSHIP

         If you tender your units in response to our offer, you will transfer to
us all right, title and interest in and to all of the units we accept, and the
right to receive all distributions in respect of such units on and after the
date on which we accept such units for purchase. Accordingly, for any units that
we acquire from you, you will not receive any future distributions from
operating cash flow of your partnership or upon a sale or refinancing of
properties owned by your partnership.

POSSIBLE INCREASE IN CONTROL OF YOUR PARTNERSHIP BY US

         Decisions with respect to the day-to-day management of your partnership
are the responsibility of the general partner. Because the general partner of
your partnership is our affiliate, we control the management of your
partnership. Under your partnership's agreement of limited partnership, limited
partners holding a majority of the outstanding units must approve certain
extraordinary transactions, including the removal of the general partner, the
addition of a new general partner, most amendments to the partnership agreement
and the sale of all or substantially all of your partnership's assets. If we
acquire 6,689.69 additional units, we will own a majority of the outstanding
units and will have the ability to control any vote of the limited partners.

RECOGNITION OF GAIN RESULTING FROM POSSIBLE FUTURE REDUCTION IN YOUR PARTNERSHIP
LIABILITIES

         Generally, a decrease in your share of partnership liabilities is
treated, for Federal income tax purposes, as a deemed cash distribution.
Although no general partner of your partnership has any 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 a general
partner to reduce the liabilities of your partnership. If you retain all or a
portion of your units and the liabilities of your partnership were to be
reduced, you would be treated as receiving a hypothetical distribution of cash
resulting from a decrease in your share of the liabilities of the 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. Gain recognized by you on the disposition of retained units
with a holding period of 12 months or less may be classified as short-term
capital gain and subject to taxation at ordinary income tax rates.

POSSIBLE TERMINATION OF YOUR PARTNERSHIP FOR FEDERAL INCOME TAX PURPOSES

         If there is a sale or exchange of 50% or more of the total interest in
capital and profits of your partnership within any 12-month period, including
sales or exchanges resulting from our offer, your partnership will terminate for
Federal income tax purposes. Any such termination may, among other things,
subject the assets of your partnership to longer depreciable lives than those
currently applicable to the assets of your partnership. This would generally
decrease the annual average depreciation deductions allocable to you for certain
years following our offer if you do not tender all of your interests in your
partnership (thereby increasing the taxable income allocable to your interests
in your partnership each such year), but would have no effect on the total
depreciation deductions available over the useful lives of the assets of your
partnership. Any such termination may also change (and possibly shorten) your
holding period with respect to interests in your partnership that you choose to
retain. Gain recognized by you on the disposition of retained units with a
holding period of 12 months or less may be classified as short-term capital gain
and subject to taxation at ordinary income tax rates.


<PAGE>   10
                                                                          Page 7


RISK OF INABILITY TO TRANSFER UNITS FOR 12-MONTH PERIOD

Your partnership's agreement of limited partnership 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 capital
and profits of 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.

POTENTIAL DELAY IN PAYMENT

         We reserve the right to extend the period of time during which our
offer is open and thereby delay acceptance for payment of any tendered units.
The offer may be extended indefinitely, and no payment will be made in respect
of tendered units until the expiration of the offer and acceptance of units for
payment.

BALLOON PAYMENT

         Your partnership has approximately $4,071,000 and $7,739,000 of balloon
payments due on its mortgage debt in December 1, 2000, and July 1, 2006,
respectively. Your partnership will have to refinance such debt, sell assets or
otherwise obtain additional funds prior to the balloon payment dates, or it will
be in default and could lose the properties to foreclosure.

                                    THE OFFER

SECTION 1.        TERMS OF THE OFFER; EXPIRATION DATE; PRORATION.

         Upon the terms and subject to the conditions of the offer, we will
accept (and thereby purchase) any and all units that are validly tendered on or
prior to the expiration date and not withdrawn in accordance with the procedures
set forth in "The Offer -- Section 4. Withdrawal Rights." For purposes of the
offer, the term "expiration date" shall mean 5:00 P.M., New York City time, on
June 13, 2000, unless we in our sole discretion shall have extended the period
of time for which the offer is open, in which event the term "expiration date"
shall mean the latest time and date on which the offer, as extended by us, shall
expire. See "The Offer -- Section 5. Extension of Tender Period; Termination;
Amendment; Subsequent Offering Period," for a description of our right to extend
the period of time during which the offer is open and to amend or terminate the
offer.

         The purchase price per unit will automatically be reduced by the
aggregate amount of distributions per unit, if any, made by your partnership to
you on or after the commencement of our offer and prior to the date on which we
acquire your units pursuant to our offer.

         If, prior to the expiration date, we increase the consideration offered
to limited partners pursuant to the offer, the increased consideration will be
paid for all units accepted for payment pursuant to the offer, whether or not
the units were tendered prior to the increase in consideration.

         If units are validly tendered prior to the expiration date and not
properly withdrawn prior to the expiration date in accordance with the
procedures set forth in "The Offer--Section 4. Withdrawal Rights" and the
purchase of all such units would result in (i) a "Rule 13e-3 transaction" within
the meaning of the Securities Exchange Act of 1934 (the "Exchange Act"), or
(ii) there being less than 320 unitholders, we will purchase only 99% of the
total number of units so tendered by each limited partner (subject to any
necessary adjustment for fractional units). If we are going to purchase only 99%
of the units validly tendered, we will notify you of such fact. In such case,
you would continue to be a limited partner and receive a K-1 for tax reporting
purposes. See "The Offer--Section 7. Effects of the Offer--Effect on Trading
Market; Registration Under 12(g) of the Exchange Act."

         The offer is conditioned on satisfaction of certain conditions. THE
OFFER IS NOT CONDITIONED UPON ANY MINIMUM NUMBER OF UNITS BEING TENDERED. See
"The Offer--Section 17. Conditions to the Offer," which sets


<PAGE>   11
                                                                          Page 8


forth in full the conditions of the offer. We reserve the right (but in no event
shall we be obligated), in our reasonable 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, we reserve the right to (i)
decline to purchase any of the units tendered, terminate the offer and return
all tendered units to tendering limited partners, (ii) waive all the unsatisfied
conditions and purchase, subject to the terms of the offer, any and all units
validly tendered, (iii) extend the offer and, subject to the withdrawal rights
of limited partners, retain the units that have been tendered during the period
or periods for which the offer is extended, or (iv) amend the offer. The
transfer of units will be effective April 1, 2000.

         This offer is being mailed to the persons shown by your partnership's
records to have been limited partners or, in the case of units owned of record
by Individual Retirement Accounts and qualified plans, beneficial owners of
units, as of May 15, 2000.

SECTION 2.        ACCEPTANCE FOR PAYMENT AND PAYMENT FOR UNITS.

         Upon the terms and subject to the conditions of the offer, we will
purchase, by accepting for payment, and will pay for any and all units validly
tendered as promptly as practicable following the expiration date. A tendering
beneficial owner of units whose units are owned of record by an Individual
Retirement 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 other documents required by the
letter of transmittal. See "The Offer--Section 3. Procedure for Tendering
Units." UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY
REASON OF ANY DELAY IN MAKING SUCH PAYMENT.

         We will, upon the terms and subject to the conditions of the offer,
accept for payment and pay for any and all units validly tendered, with
appropriate adjustments to avoid purchases that would violate the agreement of
limited partnership of your partnership and any relevant procedures or
regulations promulgated by the general partner. Accordingly, in some
circumstances, we may pay you the full offer price and accept an assignment of
your right to receive distributions and other payments and an irrevocable proxy
in respect of the units and defer, perhaps indefinitely, the transfer of
ownership of the units on the partnership books. In other circumstance we may
only be able to purchase units which, together with units previously transferred
within the preceding twelve months, do not exceed 50% of the outstanding units.

         If more units than can be purchased under the partnership agreement are
validly tendered prior to the expiration date and not properly withdrawn prior
to the expiration date in accordance with the procedures specified herein, we
will, upon the terms and subject to the conditions of the offer, accept for
payment and pay for those units so tendered which do not violate the terms of
the partnership agreement, pro rata according to the number of units validly
tendered by each limited partner and not properly withdrawn on or prior to the
expiration date, with appropriate adjustments to avoid purchases of fractional
units. If the number of units validly tendered and not properly withdrawn on or
prior to the expiration date is less than or equal to the maximum number we can
purchase under the partnership agreement, we will purchase all units so tendered
and not withdrawn, upon the terms and subject to the conditions of the offer.

         If proration of tendered units is required, then, subject to our
obligation under Rule 14e-1(c) under the Exchange Act to pay limited partners
the purchase price in respect of units tendered or return those units promptly
after termination or withdrawal of the offer, we do not intend to pay for any
units accepted for payment pursuant to the offer until the final proration
results are known. Notwithstanding any such delay in payment, no interest will
be paid on the cash offer price.

         For purposes of the offer, we will be deemed to have accepted for
payment pursuant to the offer, and thereby purchased, validly tendered units,
if, as and when we give verbal or written notice to the Information Agent of our
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 limited partners for


<PAGE>   12
                                                                          Page 9


the purpose of receiving cash payments from us and transmitting cash payments to
tendering limited partners.

         If any tendered units are not accepted for payment by us for any
reason, the letter of transmittal with respect to such units not purchased may
be destroyed by us or the Information Agent or returned to you. You may withdraw
tendered units until the expiration date (including any extensions). In
addition, if we have not accepted units for payment by July 17, 2000, you may
then withdraw any tendered units. After the expiration date, the Information
Agent may, on our behalf, retain tendered units, and those units may not be
otherwise withdrawn, if, for any reason, acceptance for payment of, or payment
for, any units tendered pursuant to the offer is delayed or we are unable to
accept for payment, purchase or pay for units tendered pursuant to the offer.
Any such action is subject, however, to our obligation under Rule 14e-1(c) under
the Exchange Act, to pay you the offer price in respect of units tendered or
return those units promptly after termination or withdrawal of the offer.

         We reserve the right to transfer or assign, in whole or in part, to one
or more of our affiliates, the right to purchase units tendered pursuant to the
offer, but no such transfer or assignment will relieve us of our obligations
under the offer or prejudice your rights to receive payment for units validly
tendered and accepted for payment pursuant to the offer.

SECTION 3.        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 one of its addresses set forth on the back cover of this offer to
purchase, on or prior to the expiration date. You may tender all or any portion
of your units. No alternative, conditional or contingent tenders will be
accepted.

         SIGNATURE REQUIREMENTS. If the letter of transmittal is signed by the
registered holder of a unit and payment is to be made directly to that holder,
then no signature guarantee is required on the letter of transmittal. Similarly,
if a unit is 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 you to tender in the offer, your 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 YOUR OPTION AND RISK 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; POWER OF ATTORNEY. By executing the letter of
transmittal, you are irrevocably appointing us and our designees as your proxy,
in the manner set forth in the letter of transmittal, each with full power of
substitution, to the fullest extent of the your rights with respect to the units
tendered by you and accepted for payment by us. 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, we accept the tendered unit for
payment. Upon such acceptance for payment, all prior proxies given by you 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). We and our designees
will, as to those units, be empowered to exercise all voting and other rights as
a limited partner as we, in our sole discretion, may deem proper at any meeting
of limited partners, by written consent or otherwise. We reserve the right to
require that, in order for units to be deemed validly tendered, immediately upon
our acceptance for payment of the units, we must be able to exercise full voting
rights with respect to the units, including voting at any meeting of limited
partners then scheduled or acting by written consent without a meeting. By
executing the letter of transmittal, you agree to execute all such documents and
take such other actions as shall be reasonably required to


<PAGE>   13
                                                                         Page 10


enable the units tendered to be voted in accordance with our directions. The
proxy granted by you to us will remain effective and be irrevocable for a period
of ten years following the termination of our offer.

         By executing the letter of transmittal, you also irrevocably constitute
and appoint us and our designees as your attorneys-in-fact, each with full power
of substitution, to the full extent of your rights with respect to the units
tendered by you and accepted for payment by us. Such appointment will be
effective when, and only to the extent that, we pay for your units will remain
effective and be irrevocable for a period of ten years following the termination
of our offer. You will agree not to exercise any rights pertaining to the
tendered units without our prior consent. Upon such payment, all prior powers of
attorney granted by you with respect to such units will, without further action,
be revoked, and no subsequent powers of attorney may be granted (and if granted
will not be effective). Pursuant to such appointment as attorneys-in-fact, we
and our designees each will have the power, among other things, (i) to transfer
ownership of such units on the partnership books maintained by your general
partner (and execute and deliver any accompanying evidences of transfer and
authenticity it may deem necessary or appropriate in connection therewith), (ii)
upon receipt by the Information Agent of the offer consideration, to become a
substituted limited partner, to receive any and all distributions made by your
partnership on or after the date on which we acquire such units, and to receive
all benefits and otherwise exercise all rights of beneficial ownership of such
units in accordance with the terms of our offer, (iii) to execute and deliver to
the general partner of your partnership a change of address form instructing the
general partner to send any and all future distributions to which we are
entitled pursuant to the terms of the offer in respect of tendered units to the
address specified in such form, and (iv) to endorse any check payable to you or
upon your order representing a distribution to which we are entitled pursuant to
the terms of our offer, in each case, in your name and on your behalf.

         By executing the letter of transmittal, you will irrevocably constitute
and appoint us and any of our designees as your true and lawful agent and
attorney-in-fact with respect to such units, with full power of substitution
(such power of attorney being deemed to be an irrevocable power coupled with an
interest), to withdraw any or all of such units that have been previously
tendered in response to any other tender or exchange offer, provided that the
price per unit we are offering is equal to or higher than the price per unit
being offered in the other tender or exchange offer. Such appointment is
effective upon the execution and receipt of the letter of transmittal and shall
continue to be effective unless and until you withdraw such units from this
offer prior to the expiration date.

         ASSIGNMENT OF INTEREST IN FUTURE DISTRIBUTIONS. By executing the letter
of transmittal, you will irrevocably assign to us and our assigns all of your
right, title and interest in and to any and all distributions made by your
partnership from any source and of any nature, including, without limitation,
distributions in the ordinary course, distributions from sales of assets,
distributions upon liquidation, winding-up, or dissolution, payments in
settlement of existing or future litigation, and all other distributions and
payments from and after the expiration date of our offer, in respect of the
units tendered by you and accepted for payment and thereby purchased by us. If,
after the unit is accepted for payment and purchased by us, you receive any
distribution from any source and of any nature, including, without limitation,
distributions in the ordinary course, distributions from sales of assets,
distributions upon liquidation, winding-up or dissolution, payments in
settlement of existing or future litigation and all other distributions and
payments, from your partnership in respect of such unit, you will agree to
forward promptly such distribution to us.

         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 our offer will be determined by us, in our reasonable
discretion, which determination shall be final and binding on all parties. We
reserve the absolute right to reject any or all tenders of any particular unit
determined by us not to be in proper form or if the acceptance of or payment for
that unit may, in the opinion of our counsel, be unlawful. We also reserve the
absolute right to waive or amend any of the conditions of the offer that we are
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 limited partner. Our interpretation of the terms and conditions
of the offer (including the letter 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.


<PAGE>   14
                                                                         Page 11


Neither us, 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 unit
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, you may have to provide us with your correct
taxpayer identification number. See the instructions to the letter of
transmittal and "The Offer--Section 6. 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 on the disposition (the amount
realized is generally the offer price plus the partnership liabilities allocable
to each unit purchased), you must certify that you are not a foreign person if
you tender units. See the instructions to the letter of transmittal and "The
Offer--Section 6. Certain Federal Income Tax Matters."

         TRANSFER TAXES. The amount of any transfer taxes (whether imposed on
the registered holder of units or any person) payable on account of the transfer
to such person will be deducted from the purchase price unless satisfactory
evidence of the payment of such taxes or exemption therefrom is submitted.

         BINDING AGREEMENT. A tender of a unit pursuant to any of the procedures
described above and the acceptance for payment of such unit will constitute a
binding agreement between the tendering unitholder and us on the terms set forth
in this offer to purchase and the related letter of transmittal.

SECTION 4.        WITHDRAWAL RIGHTS.

         You may withdraw tendered units at any time prior to the expiration
date, including any extensions thereof, or on or after July 17, 2000, if the
units have not been previously accepted for payment.

         For a withdrawal to be effective, a written notice of withdrawal must
be timely received by the Information Agent at one of its addresses set forth on
the back cover of the offer to purchase. 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 who signed the letter of transmittal in the same manner as the letter of
transmittal was signed.

         If purchase of, or payment for, a unit is delayed for any reason, or if
we are unable to purchase or pay for a unit for any reason, then, without
prejudice to our rights under the offer, tendered units may be retained by the
Information Agent; subject, however, to our obligation, pursuant to Rule
14e-1(c) under the Exchange Act, to pay the offer price in respect of units
tendered or return those units promptly after termination or withdrawal of our
offer.

         Any units properly withdrawn will thereafter be deemed not to have been
validly tendered for purposes of our offer. However, withdrawn units may be
re-tendered at any time prior to the expiration date by following the procedures
described in "The Offer--Section 3. Procedures for Tendering Units."

         All questions as to the validity and form (including time of receipt)
of notices of withdrawal will be determined by us in our reasonable discretion,
which determination will be final and binding on all parties. Neither we, 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.

SECTION 5.        EXTENSION OF TENDER PERIOD; TERMINATION; AMENDMENT; SUBSEQUENT
                  OFFERING PERIOD.

         We expressly reserve the right, in our reasonable discretion, at any
time and from time to time, (i) to extend the period of time during which our
offer is open and thereby delay acceptance for payment of, and the payment for,
any unit, (ii) to terminate the offer and not accept any units not theretofore
accepted for payment or paid for if any of the conditions to the offer are not
satisfied or if any event occurs that might reasonably be expected to result in
a


<PAGE>   15
                                                                         Page 12


failure to satisfy such conditions, (iii) upon the occurrence of any of the
conditions specified in "The Offer--Section 17. Conditions to the Offer," to
delay the acceptance for payment of, or payment for, any units not already
accepted for payment or paid for, and (iv) to amend our offer in any respect
(including, without limitation, by increasing or decreasing 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
you in a manner reasonably designed to inform you of such change. In the case of
an extension of the offer, the extension may be followed by a press release or
public announcement which will be issued no later than 9:00 a.m., New York City
time, on the next business day after the scheduled expiration date of our offer,
in accordance with Rule 14e-1(d) under the Exchange Act.

         If we extend the offer, or if we delay payment for a unit (whether
before or after its acceptance for payment) or are unable to pay for a unit
pursuant to our offer for any reason, then, without prejudice to our rights
under the offer, the Information Agent may retain tendered units and those units
may not be withdrawn except to the extent tendering unitholders are entitled to
withdrawal rights as described in "The Offer--Section 4. Withdrawal Rights";
subject, however, to our obligation, pursuant to Rule 14e-1(c) under the
Exchange Act, to pay the offer price in respect of units tendered or return
those units promptly after termination or withdrawal of the offer.

         If we make a material change in the terms of our offer, or if we waive
a material condition to our offer, we 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, if any, will depend upon the facts and circumstances, including
the materiality of the change, but generally will be five business days. 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, if
any, a minimum of ten business days from the date of such change is generally
required to allow for adequate dissemination to unitholders. Accordingly, if,
prior to the expiration date, we increase (other than increases of not more than
two percent of the outstanding units) or decrease the number of units being
sought, or increase or decrease the offer price, and if the offer is scheduled
to expire at any time earlier than the tenth business day after the date that
notice of such increase or decrease is first published, sent or given to
unitholders, the offer will be extended at least until the expiration of such
ten business days. As used in the offer to purchase, "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.

         Pursuant to Rule 14d-11 under the Exchange Act, we may be able to
provide for a subsequent offering period in tender offers for any and all
outstanding units. A subsequent offering period is an additional period of from
three to twenty business days following the expiration date of the offer
(including any extensions), in which unitholders may continue to tender units
not tendered in the offer for the offer price. In a public release, the
Securities and Exchange Commission (the "SEC") has expressed the view that the
inclusion of a subsequent offering period would constitute a material change to
the terms of the offer requiring us to disseminate new information to
unitholders in a manner reasonably calculated to inform them of such change
sufficiently in advance of the expiration date (generally five business days).
We do not plan to offer a subsequent offering period. In the event we elect to
include a subsequent offering period, we will so notify you consistent with the
requirements of the SEC.

SECTION 6.        CERTAIN FEDERAL INCOME TAX MATTERS.

         The following summary is a general discussion of certain of the United
States federal income tax consequences of the offer that may be relevant to (i)
unitholders who tender some or all of their units for cash pursuant to our
offer, and (ii) unitholders who do not tender any of their units pursuant to our
offer. This discussion is based on the Internal Revenue Code of 1986, as amended
(the "Internal Revenue Code"), Treasury Regulations, rulings issued by the
Internal Revenue Service (the "IRS"), and judicial decisions, all as of the date
of this offer to purchase. All of the foregoing are subject to change or
alternative construction, possibly with retroactive effect, and any such change
or alternative construction could affect the continuing accuracy of this
summary. This summary is

                                                                         Page 13


based on the assumption that your partnership is operated in accordance with its
organizational documents including its certificate of limited partnership and
agreement of limited partnership. 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 person 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), nor
(except as otherwise expressly indicated) does it describe any aspect of state,
local, foreign or other tax laws. This summary assumes that the units constitute
capital assets in the hands of the unitholders (generally, property held for
investment). No advance ruling has been or will be sought from the IRS regarding
any matter discussed in this offer to purchase. Further, no opinion of counsel
has been obtained with regard to the offer.

         THE UNITED STATES FEDERAL INCOME TAX TREATMENT OF A UNITHOLDER
PARTICIPATING IN THE OFFER DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT
AND INTERPRETATIONS OF COMPLEX PROVISIONS OF UNITED STATES FEDERAL INCOME TAX
LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU
SHOULD CONSULT YOUR TAX ADVISOR REGARDING THE UNITED STATES FEDERAL, STATE,
LOCAL AND FOREIGN TAX CONSEQUENCES OF SELLING THE LIMITED PARTNERSHIP INTERESTS
IN YOUR PARTNERSHIP REPRESENTED BY UNITS PURSUANT TO OUR OFFER OR OF A DECISION
NOT TO SELL IN LIGHT OF YOUR SPECIFIC TAX SITUATION.

         TAX CONSEQUENCES TO LIMITED PARTNERS TENDERING UNITS FOR CASH. You will
recognize gain or loss on a sale of a unit of limited partnership of your
partnership equal to the difference between (i) your "amount realized" on the
sale and (ii) your adjusted tax basis in the unit sold. The "amount realized"
with respect to a unit of limited partnership of your partnership will be equal
to the sum of the amount of cash received by you for the unit sold pursuant to
the offer plus the amount of partnership liabilities allocable to the unit (as
determined under Section 752 of the Internal Revenue Code). Thus, your taxable
gain and tax liability resulting from a sale of a unit of limited partnership of
your partnership could exceed the cash received upon such sale.

         ADJUSTED TAX BASIS. If you acquired your units of limited partnership
of your partnership for cash, your initial tax basis in such units was generally
equal to your cash investment in your partnership increased by your share of
partnership liabilities at the time you acquired such units. Your initial tax
basis generally has been increased by (i) your share of partnership income and
gains, and (ii) any increases in your share of partnership liabilities, and has
been decreased (but not below zero) by (i) your share of partnership cash
distributions, (ii) any decreases in your share of partnership liabilities,
(iii) your share of partnership losses, and (iv) your share of nondeductible
partnership expenditures that are not chargeable to capital. For purposes of
determining your adjusted tax basis in units of limited partnership of your
partnership immediately prior to a disposition of your units, your adjusted tax
basis in your units will include your allocable share of partnership income,
gain or loss for the taxable year of disposition. If your adjusted tax basis is
less than your share of partnership liabilities (e.g., as a result of the effect
of net loss allocations and/or distributions exceeding the cost of your unit),
your gain recognized with respect to a unit of limited partnership of your
partnership pursuant to the offer will exceed the cash proceeds realized upon
the sale of such unit.

         CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER. Except as
described below, the gain or loss recognized by you on a sale of a unit of
limited partnership of your partnership pursuant to the offer generally will be
treated as a long-term capital gain or loss if you held the unit for more than
one year. Long-term capital gains recognized by individuals and certain other
noncorporate taxpayers generally will be subject to a maximum United States
federal income tax rate of 20%. If the amount realized with respect to a unit of
limited partnership of your partnership that is attributable to your share of
"unrealized receivables" of your partnership exceeds the tax basis attributable
to those assets, such excess will be treated as ordinary income. Among other
things, "unrealized receivables" include depreciation recapture for certain
types of property. In addition, the maximum United States federal income tax
rate applicable to persons 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 units) held for more than
one year is currently 25% (rather than 20%) with respect to that portion of the
gain attributable to depreciation deductions previously taken on the property.


<PAGE>   17
                                                                         Page 14


         If you tender a unit of limited partnership interest of your
partnership in the offer, you will be allocated a share of partnership taxable
income or loss for the year of tender with respect to any units sold. You will
not receive any future distributions on units of limited partnership interest of
your partnership tendered on or after the date on which such units are accepted
for purchase and, accordingly, you may not receive any distributions with
respect to such accreted income. Such allocation and any partnership cash
distributions to you for that year will affect your adjusted tax basis in your
unit of limited partnership interest of your partnership and, therefore, the
amount of your taxable gain or loss upon a sale of a unit pursuant to the offer.

         PASSIVE ACTIVITY LOSSES. The passive activity loss rules of the
Internal Revenue Code limit the use of losses derived from passive activities,
which generally include investments in limited partnership interests such as the
units of limited partnership interest of your partnership. 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 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.

         Accordingly, if your investment in your units is treated as a passive
activity, you may be able to reduce gain from the sale of your units of limited
partnership interest of your partnership pursuant to the offer with passive
losses in the manner described below. If you sell all or a portion of your units
of limited partnership interest of your partnership pursuant to the offer and
recognize a gain on your sale, you will generally be entitled to use your
current and "suspended" passive activity losses (if any) from your partnership
and other passive sources to offset that gain. In general, if you sell all or a
portion of your units of limited partnership interest of your partnership
pursuant to the offer and recognize a loss on such sale, you will be entitled to
deduct that loss currently (subject to other applicable limitations) against the
sum of your passive activity income from your partnership for that year (if any)
plus any passive activity income from other sources for that year. If you sell
all of your units pursuant to the offer, the balance of any "suspended" losses
from your partnership that were not otherwise utilized against passive activity
income as described in the two preceding sentences will generally no longer be
suspended and will generally therefore be deductible (subject to any other
applicable limitations) by you against any other income for that year,
regardless of the character of that income. You are urged to consult your tax
advisor concerning whether, and the extent to which, you have available
"suspended" passive activity losses from your partnership or other investments
that may be used to reduce gain from the sale of units pursuant to the offer.

         INFORMATION REPORTING, BACKUP WITHHOLDING AND FIRPTA. If you tender any
units, you must report the transaction by filing a statement with your United
States federal income tax return for the year of the tender which provides
certain required information to the IRS. To prevent the possible application of
back-up United States federal income tax withholding of 31% with respect to the
payment of the offer consideration, you are generally required to provide us
with your correct taxpayer identification number. See the instructions to the
letter of transmittal.

         Gain realized by a foreign person on the sale of a unit pursuant to the
offer will be subject to federal income tax under the Foreign Investment in Real
Property Tax Act of 1980. Under these provisions of the Internal Revenue Code,
the transferee of an interest held by a foreign person in a partnership which
owns United States real property generally is required to deduct and withhold
10% of the amount realized on the disposition. Amounts withheld would be
creditable against a foreign person's United States federal income tax liability
and, if in excess thereof, a refund could be claimed from the Internal Revenue
Service by filing a United States income tax return. See the instructions to the
letter of transmittal.

         TAX CONSEQUENCES TO NON-TENDERING AND PARTIALLY-TENDERING LIMITED
PARTNERS. Section 708 of the Internal Revenue Code provides that if there is a
sale or exchange of 50% or more of the total interest in capital and profits of
a partnership within any 12-month period, such partnership terminates for United
States federal income tax purposes. It is possible that our acquisition of units
pursuant to the offer alone or in combination with other transfers of interests
in your partnership could result in such a termination of your partnership. If
your partnership


<PAGE>   18
                                                                         Page 15


is deemed to terminate for tax purposes, the following Federal income tax events
will be deemed to occur: the terminated partnership will be deemed to have
contributed all of its assets (subject to its liabilities) to a new partnership
in exchange for an interest in the new partnership and, immediately thereafter,
the old partnership will be deemed to have distributed interests in the new
partnership to the remaining limited partners in proportion to their respective
interests in the old partnership in liquidation of the old partnership.

         You will not recognize any gain or loss upon such deemed contribution
of your partnership's assets to the new partnership or upon such deemed
distribution of interests in the new partnership, and your capital account in
your partnership will carry over to the new partnership. A termination of your
partnership for Federal income tax purposes may change (and possibly shorten)
your holding period with respect to interest in you partnership that you choose
to retain. Gain recognized by you on the disposition of retained units with a
holding period of 12 months or less may be classified as short-term capital gain
and subject to taxation at ordinary income tax rates.

         A termination of your partnership for Federal income tax purpose may
also subject the assets of your partnership to longer depreciable lives than
those currently applicable to the assets of your partnership. This would
generally decrease the annual average depreciation deductions allocable to you
for certain years following our offer if you do not tender all of your interests
in your partnership (thereby increasing the taxable income allocable to your
interests in your partnership each such year), but would have no effect on the
total depreciation deductions available over the useful lives of the assets of
your partnership. Additionally, upon a termination of your partnership, the
taxable year of your partnership will close for Federal income tax purposes.

SECTION 7.        EFFECTS OF THE OFFER.

         FUTURE CONTROL BY AIMCO. Because the general partner of your
partnership is our subsidiary, we have control over the management of your
partnership. If we are successful in acquiring more than 26.02% of the units
pursuant to the offer, we will own more than 50% of the total outstanding units
and, as a result, we will be able to control the outcome of all voting decisions
with respect to your partnership. Even if we acquire a lesser number of units
pursuant to the offer, because we currently own approximately 25.18% of the
outstanding units, we will be able to significantly influence the outcome of all
voting decisions with respect to your partnership. In general, we will vote the
units owned by us in whatever manner we deem to be in our best interests, which
may not be in the interest of other limited partners. This could (1) prevent
non-tendering limited partners from taking action they desire but that we oppose
and (2) enable us to take action desired by us but opposed by non-tendering
limited partners. We also own the company that manages the residential
properties owned by your partnership. In the event that we acquire a substantial
number of units pursuant to the offer, removal of a property manager may become
more difficult or impossible.

         DISTRIBUTIONS TO US. If we acquire units in the offer, we will
participate in any subsequent distributions to limited partners to the extent of
the units purchased.

         PARTNERSHIP STATUS. We believe our purchase of units should not
adversely affect the issue of whether your partnership is classified as a
partnership for Federal income tax purposes.

         BUSINESS. Our offer will not affect the operation of the properties
owned by your partnership. We will continue to control the general partner of
your partnership and the residential property manager, both of which will remain
the same. Consummation of the offer will not affect your agreement of limited
partnership, the operations of any partnership, the business and properties
owned by your partnership, the management compensation payable to your general
partner or any other matter relating to your partnership, except it would result
in us increasing our ownership of units. We have no current intention of
changing the fee structure for your general partner or the manager of your
partnership's residential properties.

         EFFECT ON TRADING MARKET; REGISTRATION UNDER 12(g) OF THE EXCHANGE ACT.
If a substantial number of units are purchased pursuant to the offer, the result
will be a reduction in the number of limited partners in your partnership. In
the case of certain kinds of equity securities, a reduction in the number of
securityholders might be


<PAGE>   19
                                                                         Page 16


expected to result in a reduction in the liquidity and volume of activity in the
trading market for the security. In the case of your partnership, however, there
is no established public trading market for the units and, therefore, we do not
believe a reduction in the number of limited partners will materially further
restrict your ability to find purchasers for your units through secondary market
transactions.

         The units are registered under Section 12(g) of the Exchange Act, which
means, among other things, that your partnership is required to file periodic
reports with the SEC and to comply with the SEC's proxy rules. We do not expect
or intend that consummation of the offer will cause the units to cease to be
registered under Section 12(g) of the Exchange Act. If the units were to be held
by fewer than 300 persons, your partnership could apply to de-register the units
under the Exchange Act. Your partnership currently has 892 unitholders of
record. If units are tendered which would result in less than 320 unitholders,
we will purchase no more than 99% of the units tendered by each unitholder to
assure that there are more than 300 unitholders after the offer. See "The
Offer--Section 1. Terms of the Offer; Expiration Date."

         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.

         subsidiaries.

(b)      Represents AIMCO Properties, L.P.'s share of earnings from partnerships
         that own 133,113 apartment units at December 31, 1999 in which
         partnerships AIMCO Properties, L.P. owns an equity interest.

(c)      AIMCO Properties, L.P.'s management believes that the presentation of
         funds from operations or "FFO", when considered with the financial data
         determined in accordance with generally accepted accounting principles,
         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 the National Association of Real
         Estate Investment Trusts ("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. AIMCO Properties, L.P.
         calculates FFO based on the NAREIT definition, as adjusted for the
         amortization of goodwill, the non-cash deferred portion of the income
         tax provision for unconsolidated subsidiaries and less the payments of
         dividends on preferred stock. AIMCO Properties, L.P.'s 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.

</TABLE>

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

(1)      Our ratio of earnings to fixed charges 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 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.

(2)      Our ratio of earnings to combined fixed charges and preferred unit
         distributions was computed by dividing earnings by the total of fixed
         charges and preferred unit distributions. 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 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 unit distributions" consists
         of the amount of pre-tax earnings that would be required to cover
         preferred unit distributions requirements.

SECTION 9.        BACKGROUND AND REASONS FOR THE OFFER.

         GENERAL. We are in the business of acquiring direct and indirect
interests in apartment properties such as the properties owned by your
partnership. Our offer provides us with an opportunity to increase our ownership
interest in your partnership's properties while providing you and other
investors with an opportunity to liquidate your current investment.

         On October 1, 1998, AIMCO merged (the "Insignia Merger") with Insignia
Financial Group, Inc. ("Insignia"). As a result of the Insignia Merger, AIMCO
acquired approximately 51% of the outstanding common shares of beneficial
interest of Insignia Properties Trust ("IPT"). Through the Insignia Merger,
AIMCO also acquired a majority ownership interest in the entity that manages the
residential properties owned by your partnership. On October 31, 1998, IPT and
AIMCO entered into an agreement and plan of merger, dated as of October 1, 1998,
pursuant to which IPT merged with AIMCO on February 26, 1999. AIMCO then
contributed IPT's interest in Insignia Properties L. P., IPT's operating
partnership, to AIMCO's wholly owned subsidiary, AIMCO/IPT, Inc. AIMCO also
replaced IPT as the sole general partner of Insignia Properties L.P. As a
result, the general partner of your partnership is an indirect wholly owned
subsidiary of AIMCO/IPT and the residential property manager is our indirect
wholly owned subsidiary. Together with its subsidiaries, AIMCO currently owns,
in the aggregate, approximately 25.18% of your partnership's outstanding limited
partnership units.

         During our negotiations with Insignia in early 1998, we decided that if
the merger with Insignia were consummated, we could also benefit from making
offers for limited partnership interests of some of the limited partnerships
formerly controlled or managed by Insignia (the "Insignia Partnerships"). Such
offers would provide liquidity for the limited partners of the Insignia
Partnerships, and would provide AIMCO Properties, L.P. with a larger asset and
capital base and increased diversification. While some of the Insignia
Partnerships are public partnerships and information is publicly available on
such partnerships for weighing the benefits of making a tender offer, many of
the partnerships are private partnerships and information about such
partnerships comes principally from the general partner. Our control of the
general partner makes it possible for us to obtain access to such information.
Further, such control also means that we control the operations of the
partnerships and their properties. Insignia did not propose that we conduct such
tender offers, rather we initiated the offers on our own. As of the date of this
offering, AIMCO Properties, L.P. has made offers to approximately 40 of the
Insignia Partnerships, including your partnership.

         ALTERNATIVES CONSIDERED BY YOUR GENERAL PARTNER. Before we commenced
this offer, your general partner (which is our subsidiary) considered a number
of alternative transactions. The following is a brief discussion of the
advantages and disadvantages of the alternatives considered by your general
partner.

         LIQUIDATION

         One alternative would be for the partnership to sell its assets,
distribute the net liquidation proceeds to its partners in accordance with the
agreement of limited partnership, and 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, you and your partners would not need to rely
upon capitalization of income or other valuation methods to estimate the fair
market value of partnership assets. Instead, such assets would be valued through
negotiations with prospective purchasers (in many cases unrelated third
parties).

         However, in the opinion of your general partner (which is our
subsidiary), the present time may not be the most desirable time to sell the
residential real estate assets of your partnership in a private transaction, and
the proceeds realized from any such sale would be uncertain. Your general
partner believes it currently is in the best interest of your partnership to
continue holding its real estate assets. Liquidation of the partnership assets
may trigger a prepayment penalty under the mortgages for the properties.
Although there might be a prepayment penalty of approximately 1 to 2% of the
outstanding balance of the mortgages depending on when and under what
circumstances they are prepaid, such prepayment penalties are not a significant
factor in determining when a

                                                                         Page 21


property may be sold. See "The Offer--Section 13. Certain Information Concerning
Your Partnership--Investment Objectives and Policies; Sale or Financing of
Investments."

         CONTINUATION OF THE PARTNERSHIP WITHOUT THE OFFER

         A second alternative 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 agreement of limited partnership, without our offer. A
number of advantages could result from the continued operation of your
partnership. Given improving rental market conditions or improved operating
performance, the level of distributions might increase over time. It is possible
that the private resale market for properties could improve over time, making a
sale of the partnership's properties in a private transaction at some point in
the future a more attractive option than it is currently. The continuation of
your partnership will allow you to continue to participate in the net income and
any increases in revenue of your partnership and any net proceeds from the sale
of any property owned by your partnership. However, no assurance can be given as
to future operating results or as to the results of any attempts to sell any
property owned by your partnership.

         There are several risks and disadvantages that result from continuing
the operations of your partnership without our offer. 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 without our offer would deny you and your
partners the benefits of our offer. For example, you might have no opportunity
for liquidity unless you were to sell your units in a private transaction. Any
such sale would likely be at a discount from your pro rata share of the fair
market value of the properties owned by your partnership.

         SALE OF ASSETS

         Your partnership could sell the properties it owns and not liquidate.
Your general partner (which is our subsidiary) considers the sale of partnership
properties from time to time. However, any such sale would likely be a taxable
transaction, and, without a liquidating distribution, would not provide limited
partners with any cash to pay any tax liabilities arising as a result thereof.

         ALTERNATIVE TRANSACTIONS CONSIDERED BY US. Before we decided to make
our offer, we considered a number of alternative transactions, including
purchasing some or all of your partnership's properties or merging your
partnership with us. However, both of these alternatives would require a vote of
all the limited partners. If the transaction was approved, all limited partners,
including those who wish to continue to participate in the ownership of your
partnership's properties, would be forced to participate in the transaction. If
the transaction was not approved, all limited partners, including those who
would like to dispose of their investment in your partnership's properties,
would be forced to retain their investment. We also considered an offer to
exchange units in your partnership for units of AIMCO Properties, L.P. However,
because of the expense and delay associated with making such an exchange offer,
we decided to make an offer for cash only. In addition, our historical
experience has been that most holders of limited partnership units, when given a
choice, prefer cash.

         DETERMINATION OF OFFER PRICE. In establishing the offer price, we
reviewed certain publicly available information and certain information made
available to us by the general partner (which is our subsidiary) and our other
affiliates, including among other things: (i) the agreement of limited
partnership, as amended to date; (ii) the partnership's Annual Report on Form
10-KSB for the year ended December 31, 1999; (iii) the operating budgets
prepared by the property manager with respect to the partnership's properties
for the year ending December 31, 2000; and (iv) tender offer statements,
solicitation/recommendation statements and beneficial ownership reports on
Schedules TO, 14D-1, 14D-9 and 13D. Our determination of the offer price was
based on our review and analysis of the foregoing information, the other
financial information and the analyses concerning the partnership summarized
below.

         VALUATION OF UNITS. We determined our offer price by estimating the
value of each residential property owned by your partnership using the direct
capitalization method. This method involves applying a capitalization


<PAGE>   25
                                                                         Page 22


rate to your partnership's annual residential property income. A capitalization
rate is a percentage (rate of return), commonly applied by purchasers of
residential real estate to property income to determine the present value of
income Property. The lower the capitalization rate utilized the higher the value
produced, and the higher the capitalization rate utilized the lower the value
produced. We used your partnership's property income for the year ended December
31, 1999. Our method for selecting a capitalization rate begins with each
property being assigned a location and condition rating (e.g., "A" for
excellent, "B" for good, "C" for fair, and "D" for poor). We then adjust the
capitalization rate based on whether the property's mortgage debt bears interest
at a rate above or below 7.5% per annum. Generally, for every 0.5% in excess of
7.5%, the capitalization rate would be increased by 0.25% The evaluation of a
property's location and condition, and the determination of an appropriate
capitalization rate for a property, is subjective in nature, and others
evaluating the same property might use a different capitalization rate and
derive a different property value.

         Property income is the difference between the revenues from the
property and related costs and expenses, excluding income derived from sources
other than its regular activities and before income deductions. Income
deductions include interest, income taxes, prior-year adjustments, charges to
reserves, write-off of intangibles, adjustments arising from major changes in
accounting methods and other material and nonrecurring items. In this respect,
property income differs from net income disclosed in the partnership's financial
statements, which does not exclude these income sources and deductions. The
following is a reconciliation of your partnership's property income for the year
ended December 31, 1999 to your partnership's net operating income for the same
period:

</TABLE>

         Although the direct capitalization method is a widely accepted way of
valuing real estate, there are a number of other methods available to value real
estate, each of which may result in different valuations of a property. Further,
in applying the direct capitalization method, others may make different
assumptions and obtain different results. The proceeds that you would receive if
you sold your units to someone else or if your partnership were actually
liquidated might be higher than our offer price.

         We determined our offer price as follows:

         o        First, we estimated the value of the residential property
                  owned by your partnership using the direct capitalization
                  method. We selected capitalization rates 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
                  (property income less capital reserves divided by sales price)
                  and then evaluated each property in light of its relative
                  competitive position, taking into account property location,
                  occupancy rate, overall property condition and other relevant
                  factors. We believe 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
                  used property income for 1999 and then divided such amount by
                  the property's capitalization rate to derive an estimated
                  gross property value as described in the following table.

         o        Sunflower Apartments, located in Dallas, Texas is currently
                  being marketed for a sale price of $7,250,000. There can be no
                  assurance, however, that such property will be sold or the
                  price or costs of any sale. If we have received any offers to
                  purchase a property, the value we ascribed to such property is
                  the highest offer, if any, which is then discounted to reflect
                  the uncertainty of the actual closing price for a sale and the
                  likelihood of price negotiations up until the closing date.

         Based on the above, we estimated the gross property value of each
property as follows:

         o        Second, we calculated the value of the equity of your
                  partnership by adding to the aggregate gross property value of
                  all properties owned by your partnership, the value of the
                  non-real estate assets of your partnership, and deducting the
                  liabilities of your partnership, including mortgage debt and
                  debt, if any, owed by your partnership to its general partner
                  (which is our subsidiary) or its affiliates after
                  consideration of any applicable subordination provisions
                  affecting payment of such debt. We deducted from this value
                  certain other costs, including required capital expenditures,
                  deferred maintenance, and closing costs, to derive a net
                  equity value for your partnership of $11,465,606. Closing
                  costs, which are estimated to be 5% of the gross property
                  value, include legal and accounting fees, real property
                  transfer taxes, title and escrow costs and broker's fees.

         o        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's agreement of limited partnership. Accordingly,
                  100% of the estimated liquidation proceeds are assumed to be
                  distributed to holders of units. Our offer price represents
                  the per unit liquidation proceeds determined in this manner.

         COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION. To assist
holders of units in evaluating the offer, your general partner (which is our
affiliate) has attempted to compare the offer price against: (a) prices at which
the units have sold in the secondary market and (b) estimates of the value of
the units on a liquidation basis. The general partner of your partnership
believes that analyzing the alternatives in terms of estimated value, 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.


<PAGE>   27
                                                                         Page 24


         The results of these comparative analyses are summarized in the chart
below. You should bear in mind that some of the alternative values are based on
a variety of assumptions that have been made by us. These assumptions relate to,
among other things, the operating results, if any, since December 31, 1999 as to
income and expenses of the property, other projected amounts and the
capitalization rates that may be used by prospective buyers if your partnership
assets were to be liquidated.

         In addition, these estimates are based upon certain information
available to your general partner (which is our affiliate) 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. 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's properties is sold and
changes in availability of capital to finance acquisitions of apartment
properties.

         Under your partnership's agreement of limited partnership, the term of
the partnership will continue until December 31, 2003, unless sooner terminated
as provided in the agreement or by law. Limited partners could, as an
alternative to tendering their units, take a variety of possible actions,
including voting to liquidate the partnership or amending the agreement of
limited partnership to authorize limited partners to cause the partnership to
merge with another entity or engage in a "roll-up" or similar transaction.

              In April, 1999, we commenced a tender offer at the original offer
price of $284 per unit. We determined the offer price using the same basic
method for the current offer but used property income for an earlier period.

              In our July, 1999 tender offer, we offered a price of $284 per
unit.

              We are aware that tender offers may have been made by unaffiliated
third parties to acquire units in your partnership in exchange for cash. We are
unaware of the amounts offered, terms, tendering parties or number of units
involved in these tender offers. In connection with tender offers made by
Insignia affiliates with respect to partnerships for which we are making offers,
some limited partners filed lawsuits, all but one of which have been settled. We
are not aware of any merger, consolidation or other combination involving any of
the Insignia Partnerships, or any acquisitions of any of such partnerships or a
material amount of the assets of such partnerships.

              PRICES ON SECONDARY MARKET

              Secondary market sales information is not a reliable measure of
value because of the limited amount of any known trades. At present, privately
negotiated sales and sales through intermediaries are the only means which may
be available to a limited partner to liquidate an investment in units (other
than our offer) because the units are not listed or traded on any exchange or
quoted on NASDAQ, on the Electronic Bulletin Board, or in "pink sheets."
Secondary sales activity for the units, including privately negotiated sales,
has been limited and sporadic.

         ESTIMATED LIQUIDATION PROCEEDS

         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. Your general
partner (which is our subsidiary) estimated the liquidation value of units using
the same direct capitalization method and assumptions as we did in valuing the
units for the offer price. The liquidation analysis assumes that your
partnership's properties are 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 are sold at their book value, and
that the net proceeds of sale are allocated to your partners in accordance with
your partnership's agreement of limited partnership.

         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 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 are disposed of in an orderly manner and are
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. We have allocated to the limited partners
the amount of the estimated net valuation of your partnership based on your
partnership's agreement of limited partnership as if your partnership was being
liquidated at the current time.

SECTION 10.    POSITION OF THE GENERAL PARTNER OF YOUR PARTNERSHIP WITH RESPECT
               TO THE OFFER.

         The partnership and the general partner of your partnership have
provided the following information for inclusion in this Offer to Purchase:

         The general partner of your partnership believes the offer price and
the structure of the transaction are fair to the limited partners. In making
such determination, the general partner considered all of the factors and
information set forth below, but did not quantify or otherwise attach particular
weight to any such factors or information:

         o        The offer gives you an opportunity to make an individual
                  decision on whether to tender your units or to continue to
                  hold them.

         o        The offer price and the method used to determine the offer
                  price.

         o        The fact that the price offered for your units is based on an
                  estimated value of your partnership's properties that has been
                  determined using a method believed to reflect the valuation of
                  such assets by buyers in the market for similar assets.

         o        Prices at which the units have recently sold, to the extent
                  such information is available.

         o        The absence of an established trading market for your units.

         o        An analysis of possible alternative transactions, including a
                  property sale, or a liquidation of the partnership.

         o        An evaluation of the financial condition and results of
                  operations of your partnership.

         The general partner of your partnership is remaining neutral and makes
no recommendation as to whether you should tender or refrain from tendering your
units in the offer. Although the general partner believes our offer is fair, the
general partner also believes that you must make your own decision whether or
not to participate in any offer, based upon a number of factors, including
several factors that may be personal to you, such as your financial position,
your need or desire for liquidity, your preferences regarding the timing of when
you might wish to sell your units, other financial opportunities available to
you, and your tax position and the tax consequences to you of selling your
units.

         Neither the general partner of your partnership or its affiliates have
any plans or arrangements to tender any units. Except as otherwise provided in
"The Offer-Section 12. Future Plans of the Purchaser," the general partner does
not have any present plans or proposals which relate to or would result in an
extraordinary transaction, such as a merger, reorganization or liquidation,
involving your partnership; a purchase or sale or transfer of a material amount
of your partnership's assets; or any changes in your partnership's present
capitalization, indebtedness or distribution policies. For information relating
to certain relationships between your partnership and its general partner, on
one hand, and AIMCO and its affiliates, on the other and conflicts of interests
with respect to the tender offer, see "The Offer--Section 9. Background and
Reasons for the Offer" and "The Offer--Section 11. Conflicts of Interests and
Transactions with Affiliates." See also "The Offer--Section 9. Background and
Reasons for the Offer--Comparison to Alternative Consideration--Prior Tender
Offers" and "The Offer--Section 13.

                                                                         Page 27


Certain Information Concerning Your Partnership--Beneficial Ownership of
Interests in Your Partnership," for certain information regarding transactions
in units of your partnership.

SECTION 11.       CONFLICTS OF INTEREST AND TRANSACTIONS WITH AFFILIATES.

         CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER. The general partner of
your partnership became a majority-owned subsidiary of AIMCO on October 1, 1998,
when AIMCO merged with Insignia. Your general partner became a wholly owned
subsidiary of AIMCO on February 26, 1999, when IPT merged with AIMCO.
Accordingly, the general partner of your partnership 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 AIMCO. As a consequence of our ownership of units, we may have
incentives to seek to maximize the value of our ownership of units, which in
turn may result in a conflict for your general partner in attempting to
reconcile our interests with the interests of the other limited partners.
Additionally, we desire to purchase units at a low price and you desire to sell
units at a high price. The general partner of your partnership makes no
recommendation as to whether you should tender or refrain from tendering your
units. Such conflicts of interest in connection with the offer and the operation
of AIMCO differ from those conflicts of interest that currently exist for your
partnership. Your general partner has filed a Solicitation/Recommendation
Statement on Schedule 14D-9 with the SEC, which indicates that it is making no
recommendation as to whether limited partners should tender their units pursuant
to the offer. LIMITED PARTNERS ARE URGED TO READ THIS OFFER TO PURCHASE IN ITS
ENTIRETY BEFORE DECIDING WHETHER TO TENDER THEIR UNITS.

         CONFLICTS OF INTEREST THAT CURRENTLY EXIST FOR YOUR PARTNERSHIP. We own
both the general partner of your partnership and the property manager of your
partnership's residential properties. The general partner of your partnership
received total fees and reimbursements of $41,000 in 1997, $76,000 in 1998 and
$162,000 in 1999. The property manager for the residential properties received
management fees of $259,000 in 1997, $362,000 in 1998 and $383,000 in 1999. We
have no current intention of changing the fee structure for your general partner
or the manager of your partnership's residential properties.

         COMPETITION AMONG PROPERTIES. Because AIMCO and your partnership both
invest in apartment properties, these properties may compete with one another
for tenants. Furthermore, you should bear in mind that AIMCO may acquire
properties in general market areas where your partnership properties are
located. 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 AIMCO's properties, we
will attempt to reduce conflicts between competing properties by referring
prospective customers to the property considered to be most conveniently located
for the customer's needs.

         FUTURE OFFERS. Although we have no current plans to conduct future
tender offers for your units, our plans may change based on future
circumstances, including tender offers made by third parties. Any such future
offers that we might make could be for consideration that is more or less than
the consideration we are currently offering.

SECTION 12.       FUTURE PLANS OF THE PURCHASER.

         As described above under "The Offer - Section 9. Background and Reasons
for the Offer," we own the general partner and thereby control the management of
your partnership. In addition, we own the manager of the residential properties.
We currently intend that, upon consummation of the offer, we will hold the units
acquired and 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 partnership operations.

         Although we have no present intention to do so, we may acquire
additional units or sell units after completion or termination of the offer. Any
acquisition may be made through private purchases, 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 this offer,


<PAGE>   31
                                                                         Page 28


and may be for cash, limited partnership interests in AIMCO Properties, L.P. or
other consideration. We also may consider selling some or all of the units we
acquire pursuant to the offer to persons not yet determined, which may include
our affiliates. We may also buy your partnership's properties, although we have
no present intention to do so. There can be no assurance, however, that we will
initiate or complete, or will cause your partnership to initiate or complete,
any subsequent transaction during any specific time period following the
expiration of the offer or at all.

         Except as set forth herein, we do not have any present plans or
proposals which relate to or would result in an extraordinary transaction, such
as a merger, reorganization or liquidation, involving your partnership; a
purchase or sale or transfer of a material amount of your partnership's assets;
any changes in composition of your partnership's senior management or personnel
or their compensation; any changes in your partnership's present capitalization,
indebtedness or distribution policy; or any other material changes in your
partnership's structure or business. We or our affiliates may loan funds to your
partnership which may be secured by your partnership's properties. If any such
loans are made, upon default of such loans, we or our affiliates could seek to
foreclose on the loan and related mortgage or security interest. However, we
expect that consistent with your general partner's fiduciary obligations, the
general partner will seek and review opportunities (including opportunities
identified by us) to engage in transactions which could benefit your
partnership, such as sales or refinancings of assets or a combination of the
partnership with one or more other entities, with the objective of seeking to
maximize returns to limited partners.

         We have been advised that the possible future transactions the general
partner expects to consider on behalf of your partnership include: (1) payment
of extraordinary distributions; (2) refinancing, reducing or increasing existing
indebtedness of the partnership; (3) sales of assets, individually or as part of
a complete liquidation; and (4) mergers or other consolidation transactions
involving the partnership. Any such merger or consolidation transaction could
involve other limited partnerships in which your general partner or its
affiliates serve as general partners, or a combination of the partnership with
one or more existing, publicly traded entities (including, possibly, affiliates
of AIMCO), in any of which limited partners might receive cash, common stock or
other securities or consideration. There is no assurance, however, as to when or
whether any of the transactions referred to above might occur. If any such
transaction is effected by the partnership and financial benefits accrue to the
limited partners of your partnership, we will participate in those benefits to
the extent of our ownership of units. The agreement of limited partnership
prohibits limited partners from voting on actions taken by the partnership,
unless otherwise specifically permitted therein. Limited partners may vote on a
liquidation, and if we are successful in acquiring a substantial number of units
pursuant to the offer, we will be able to control the outcome of any such vote.
Even if we acquire a lesser number of units pursuant to the offer, however,
because we currently own approximately 25.18% of the outstanding limited
partnership units we will be able to significantly influence the outcome of any
such vote. Our primary objective in seeking to acquire the units pursuant to the
offer is not, however, to influence the vote on any particular transaction, but
rather to generate a profit on the investment represented by those units.

SECTION 13.       CERTAIN INFORMATION CONCERNING YOUR PARTNERSHIP.

         GENERAL. Winthrop Growth Investors 1 Limited Partnership was organized
on June 20, 1983 under the laws of the Commonwealth of Massachusetts. Its
primary business is real estate ownership and related operations. Your
partnership was formed for the purpose of making investments in various types of
real properties which offer potential capital appreciation and cash
distributions to its limited partners.

         Your partnership's investment portfolio currently consists of the
following four residential apartment complexes: Sunflower Apartments, a 248-unit
complex in Dallas, TX; Ashton Ridge Apartments (formerly Meadow Wood
Apartments), a 356-unit complex in Jacksonville, FL; Stratford Place Apartments,
a 350-unit complex in Gaithersburg, MD; and Stratford Village Apartments, a
224-unit complex in Montgomery, AL.

         The general partner of your partnership is Two Winthrop Properties
Inc., which is a wholly owned subsidiary of AIMCO. A wholly owned subsidiary of
AIMCO serves as manager of the residential properties owned by your partnership.
As of March 31, 2000, there were 23,139 units issued and outstanding, which were

                                                                         Page 29


held of record by 892 limited partners. Your partnership's principal executive
offices are located at Colorado Center, Tower Two, 2000 South Colorado
Boulevard, Suite 2-1000, Denver, Colorado 80222, and its telephone number at
that address is (303) 757-8101.

         For additional information about your partnership, please refer to the
annual report prepared by your partnership particularly Item 2 of Form 10-KSB
which contains detailed information regarding the properties owned, including
mortgages, rental rates and taxes.

         INVESTMENT OBJECTIVES AND POLICIES; SALE OR FINANCING OF INVESTMENTS.
In general, your general partner (which is our subsidiary) regularly evaluates
the partnership's properties by considering various factors, such as the
partnership's financial position and real estate and capital markets conditions.
The general partner monitors the properties' specific locale and sub-market
conditions (including stability of the surrounding neighborhood) evaluating
current trends, competition, new construction and economic changes. The general
partner oversees each asset's operating performance and continuously evaluates
the physical improvement requirements. In addition, the financing structure for
each property (including any prepayment penalties), tax implications,
availability of attractive mortgage financing to a purchaser, and the investment
climate are all considered. Any of these factors, and possibly others, could
potentially contribute to any decision by the general partner to sell,
refinance, upgrade with capital improvements or hold a particular partnership
property. If rental market conditions improve, the level of distributions might
increase over time. It is possible that the private resale market for
residential properties could improve over time, making a sale of the
partnership's properties in a private transaction at some point in the future a
more viable option than it is currently. After taking into account the foregoing
considerations, your general partner is not currently seeking a sale of your
partnership's residential properties primarily because it expects the
properties' operating performance to improve in the near term. In particular,
the general partner noted that it expects to spend approximately $946,616 for
capital improvements at the residential properties in 2000 to repair and update
the properties. Although there can be no assurance as to future performance,
however, these expenditures are expected to improve the desirability of the
property to tenants. The general partner does not believe that a sale of the
residential properties at the present time would adequately reflect the
properties' future prospects. Another significant factor considered by your
general partner is the likely tax consequences of a sale of the residential
properties for cash. Such a transaction would likely result in tax liabilities
for many limited partners. The general partner has not received any recent
indication of interest or offer to purchase the residential properties.

         ORIGINALLY ANTICIPATED TERM OF YOUR PARTNERSHIP. Your partnership's
prospectus, dated May 11, 1984, pursuant to which units in your partnership were
sold, indicated that your partnership was intended to be self-liquidating and
that it was anticipated that the partnership's properties would be sold prior to
its dissolution date, provided market conditions permit. The prospectus also
indicated that there could be no assurance that the partnership would be able to
so liquidate and that, unless sooner terminated as provided in the partnership
agreement, the existence of the partnership would continue until the year 2003.
The partnership currently owns four apartment properties. Your general partner
(which is our subsidiary) continually considers whether a property should be
sold or otherwise disposed of after consideration of relevant factors, including
prevailing economic conditions, availability of favorable financing and tax
considerations, with a view to achieving maximum capital appreciation for your
partnership. We cannot predict when any of the properties will be sold or
otherwise disposed of. However, there is no current plan or intention to sell
the residential properties in the near future.

         Under your partnership's agreement of limited partnership, the term of
the partnership will continue until December 31, 2003, unless sooner terminated
as provided in the agreement or by law. Limited partners could, as an
alternative to tendering their units, take a variety of possible actions,
including voting to liquidate the partnership or amending the agreement of
limited partnership to authorize limited partners to cause the partnership to
merge with another entity or engage in a "roll-up" or similar transaction.

         CAPITAL REPLACEMENTS. Your partnership has 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, which are
budgeted at $946,616 for 2000, are expected to be paid

                                                                         Page 30


from operating cash flows, cash reserves, or from short-term or long-term
borrowings.

         COMPETITION. There are other residential properties within the market
area of your partnership's properties. The number and quality of competitive
properties in such an area could have a material effect on the rental market for
the apartments at your partnership's properties and the rents that may be
charged for such apartments. While AIMCO is a significant factor in the United
States in the apartment industry, competition for apartments is local. According
to data published by the National Multi-Housing Council, as of January 1, 1999,
our portfolio of 373,409 owned or managed apartment units represents
approximately 2.2% of the national stock of rental apartments in structures with
at least five apartments.

         FINANCIAL DATA. The selected financial information of your partnership
set forth below for the years ended December 31, 1999 and 1998 is based on
audited financial statements. This information should be read in conjunction
with such financial statements, including notes thereto, and "Management's
Discussion and Analysis of Financial Condition and Results of Operations of Your
Partnership" in the Annual Report on Form 10-KSB of your partnership for the
year ended December 31, 1999.

         The above budget, at the time it was made, was forward-looking
information developed by the general partner of your partnership. Therefore, the
budget was dependent upon future events with respect to the ability of your
partnership to meet such budget. The budget incorporated various assumptions
including, but not limited to, revenue (including occupancy rates), various
operating expenses, general and administrative expenses, capital expenditures,
and working capital levels. While the general partner deemed such budget to be
reasonable and valid at the date made, there is no assurance that the assumed
facts will be validated or that the budgeted results will actually occur. Any
estimate of the future performance of a business, such as your partnership's
business, is forward-looking and based on assumptions some of which inevitably
will prove to be incorrect.

         The budget amounts provided above are figures that were not computed in
accordance with GAAP. In particular, items that are categorized as capital
expenditures for purposes of preparing the operating budget are often

re-categorized as expenses when the financial statements are audited and
presented in accordance with GAAP. Therefore, the summary operating budget
presented for fiscal 2000 should not necessarily be considered as indicative of
what the audited operating results for fiscal 2000 will be.

         BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP. Together with
our subsidiaries, we currently own, in the aggregate, approximately 25.18% your
partnership's limited partnership units. Except as set forth above, neither we,
nor, to the best of our knowledge, any of our affiliates, (i) beneficially own
or have a right to acquire any units, (ii) has effected any transactions in the
units in the past 60 days, 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.

         COMPENSATION PAID TO THE GENERAL PARTNER AND ITS AFFILIATES. The
following table shows, for each of the years indicated, compensation paid to

         LEGAL PROCEEDINGS. Your partnership may be a party to a variety of
legal proceedings related to its ownership of the partnership's properties,
arising in the ordinary course of the business, which are not expected to have a
material adverse effect on your partnership.

         ADDITIONAL INFORMATION CONCERNING YOUR PARTNERSHIP. Your partnership
files annual, quarterly and special reports, proxy statements and other
information with the SEC. You may read and copy any document your partnership
files at the SEC's public reference rooms in Washington, D.C., New York, New
York, and Chicago, Illinois. Please call the SEC at 1-800-SEC-0330 for further
information on the public reference rooms. Your partnership's SEC filings are
also available to the public at the SEC's web site at http://www.sec.gov.

SECTION 14.       VOTING POWER.

         Decisions with respect to the day-to-day management of your partnership
are the responsibility of the general partner. Because the general partner of
your partnership is our affiliate, we control the management of your
partnership. Under your partnership's agreement of limited partnership, limited
partners holding a majority of the outstanding units must approve certain
extraordinary transactions, including the removal of the general partner, the
addition of a new general partner, most amendments to the partnership agreement
and the sale of all or substantially all of your partnership's assets. If we
acquire 6,689.69 additional units that we are offering to purchase, we will own
a majority of the outstanding units and will have the ability to control any
vote of the limited partners.

SECTION 15.       SOURCE OF FUNDS.

         We expect that approximately $8,982,252 will be required to purchase
all of the limited partnership units that we are seeking in this offer
(exclusive of fees and expenses estimated to be $15,000). For more information
regarding fees and expenses, see "The Offer - Section 19. Fees and Expenses."

         In addition to this offer, we are concurrently making offers to acquire
interest in approximately 40 other limited partnerships. If all such offers were
fully subscribed for cash, we would be required to pay approximately $187
million for all such units. If for some reason we did not have such funds
available we might extend this offer


<PAGE>   37
                                                                         Page 34


for a period of time sufficient for us to obtain additional funds, or we might
terminate this offer. However, based on our past experience with similar offers,
we do not expect all such offers to be fully subscribed. As a result, we expect
that the funds that will be necessary to consummate all the offers will be
substantially less than $187 million. We believe that we have sufficient cash on
hand and available sources of financing to pay such amounts. As of March 31,
2000, we had $22 million of cash on hand and $90 million available for borrowing
under our existing lines of credit.

         Under our secured $350 million revolving credit facility with Bank of
America, BankBoston, N.A. and First Union National Bank, AIMCO Properties, L.P.
is the borrower and all obligations thereunder are guaranteed by AIMCO and
certain of its subsidiaries. The credit facility includes a swing line of up to
$30 million. The obligations under the credit facility are secured by AIMCO
Properties, L.P.'s pledge of its stock ownership in certain subsidiaries of
AIMCO as well as a pledge of its interests in notes issued by it to certain
subsidiaries of AIMCO. The annual interest rate under the credit facility is
based on either LIBOR or a base rate which is the higher of Bank of America's
reference rate or 0.5% over the federal funds rate, plus, in either case, an
applicable margin. The margin ranges between 2.05% and 2.55% in the case of
LIBOR-based loans and between 0.55% and 1.05% in the case of base rate loans,
based upon a fixed charge coverage ratio. The credit facility expires on July
31, 2001 unless extended at the discretion of AIMCO Properties, L.P., at which
time the revolving facility would be converted into a term loan for up to two
successive one-year periods. The financial covenants contained in the credit
facility require us to maintain a ratio of debt to gross asset value of no more
than 0.55 to 1.0, and an interest coverage ratio of 2.25 to 1.0, and a fixed
charge coverage ratio of at least 1.75 to 1.0. In addition, the credit facility
limits us from distributing more than 80% of our Funds From Operations (as
defined) (or such amounts as may be necessary for us to maintain our status as a
REIT), imposes minimum net worth requirements and provides other financial
covenants related to certain of our assets and obligations.

SECTION 16.       DISSENTERS' RIGHTS.

         Neither the agreement of limited partnership of your partnership nor
applicable law provides any right for you to have your units appraised or
redeemed in connection with, or as a result of, our offer. You have the
opportunity to make an individual decision on whether or not to tender your
units in the offer.

SECTION 17.       CONDITIONS OF THE OFFER.

         Notwithstanding any other provisions of our offer, we will not be
required to accept for payment and pay for any units tendered pursuant to our
offer, may postpone the purchase of, and payment for, units tendered, and may
terminate or amend our offer if at any time on or after the date of this offer

extension thereof), any of the following shall occur or may be reasonably

natural disaster, casualty loss, or act of God that, in our reasonable judgment,
are or may be materially adverse to your partnership or the value of the units
to us, or we shall have become aware of any facts relating to your partnership,
its indebtedness or its operations which, in our reasonable judgment, has or may
have material significance with respect to the value of your partnership or the

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 our
purchase of the units, restrains, prohibits or delays the making or consummation
of our offer, prohibits the performance of any of the contracts or other

material amount of damages as a result of the transactions contemplated by our
offer, (ii) seeks to make the purchase of, or payment for, some or all of the
units pursuant to our offer illegal or results in a delay in our ability to
accept for payment or pay for some or all of the units, (iii) seeks to prohibit
or limit the ownership or operation by us or any of our affiliates of the entity
serving as general partner of your partnership or to remove such entity as

on our ability or the ability of any affiliate of ours to conduct your
partnership's business or own such assets, (iv) seeks to impose material
limitations on our ability to acquire or hold or to exercise full rights of

         (d) there shall be any action taken, or any statute, rule, regulation,
order or injunction shall be sought, proposed, enacted, promulgated, entered,
enforced or deemed applicable to our offer, your partnership, any general
partner of your partnership, us or any affiliate of ours or your partnership, or
any other action shall have been taken, proposed or threatened, by any
government, governmental authority or court, that, in our reasonable judgment,
might, directly or indirectly, result in any of the consequences referred to in
clauses (i) through (v) of paragraph (c) above; or

         (e) your partnership shall have (i) changed, or authorized a change of,
the units or your partnership's capitalization, (ii) issued, distributed, sold
or pledged, or authorized, proposed or announced the issuance, distribution,
sale or pledge of (A) any equity interests (including, without limitation,

SECTION 18.       CERTAIN LEGAL MATTERS.

         GENERAL. Except as set forth in this Section 18, we are not, based on
information provided by your general partner (which is our subsidiary), 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 our
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 us pursuant to the offer, other than the filing of a
Tender Offer Statement on Schedule TO with the SEC (which has already been
filed) and any required amendments thereto. 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 or its business, or that certain parts of its
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 us to elect to terminate the offer without purchasing units thereunder.
Our obligation to purchase and pay for units is subject to certain conditions,
including conditions related to the legal matters discussed in this Section 18.

         ANTITRUST. We do not believe that the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, is applicable to the acquisition of units
contemplated by our 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 our offer.

         STATE LAWS. We are not aware of any jurisdiction in which the making of
our 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.
If, after such good faith effort, we cannot comply with any such law, the offer
will not be made to (nor will tenders be accepted from or on behalf of)
unitholders residing in such jurisdiction. In those jurisdictions with
securities or blue sky laws that require the offer to be made by a licensed
broker or dealer, the offer shall be made on behalf of us, if at all, only by
one or more registered brokers or dealers licensed under the laws of that
jurisdiction.

SECTION 19.       FEES AND EXPENSES.

         Except as set forth herein, 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 have retained River Oaks Partnership Services, Inc. to act as
Information Agent in connection with our offer. The Information Agent may
contact holders of units by mail, e-mail, telephone, telex, telegraph and
personal interview and may request brokers, dealers and other nominee limited
partners to forward materials relating to the offer to beneficial owners of the
units. 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 it 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
the offer and any related legal fees and expenses.

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

         NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY
REPRESENTATION ON BEHALF OF US NOT CONTAINED HEREIN OR IN THE LETTER OF
TRANSMITTAL AND, IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATION MUST NOT
BE RELIED UPON AS HAVING BEEN AUTHORIZED.

         We have filed with the SEC a Tender Offer Statement on Schedule TO,
pursuant to Section 14(d)(1) and Rule 14d-3 under the Exchange Act, furnishing
certain additional information with respect to our offer, and may file
amendments thereto. Your partnership has filed with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 pursuant to Section
14(d)(4) and Rule 14d-9 under the Exchange Act, furnishing certain additional
information about your partnership's and the general partner's position
concerning our offer, and your partnership may file amendments thereto. The
Schedules TO and 14D-9 and any amendments to either Schedule, including
exhibits, may be inspected and copies may be obtained at the same place and in
the same manner as described in "The Offer--Section 13. Certain Information
Concerning Your Partnership--Additional Information Concerning Your
Partnership."

Ladies and Gentlemen:

     The Signatory (the "Signatory") executing the Acknowledgment and Agreement
relating to the captioned offer (the "Acknowledgment and Agreement"), which is
enclosed, upon the terms and subject to the conditions set forth in the Offer,
hereby and thereby tenders to the Purchaser the units set forth in the box
entitled "Description of Units Tendered" on the Acknowledgment and Agreement,
including all interests in any limited partnership represented by such units
(collectively, the "Units"), at the price indicated in the Offer as supplemented
or amended, less the amount of distributions, if any, made or declared by the
Partnership from the Offer Date until the Expiration Date (the "Offer Price"),
net to the Signatory in cash, without interest. Capitalized terms used herein
but not otherwise defined herein shall have the meanings ascribed thereto in
such Acknowledgment and Agreement.

     Subject to and effective upon acceptance for payment of any of the Units
tendered hereby and thereby in accordance with the terms of the Offer, the
Signatory hereby and thereby irrevocably sells, assigns, transfers, conveys and
delivers to, or upon the order of, the Purchaser all right, title and interest
in and to such Units tendered hereby and thereby that are accepted for payment
pursuant to the Offer, including, without limitation, (i) all of the Signatory's
interest in the capital of the Partnership, and the Signatory's interest in all
profits, losses and distributions of any kind to which the Signatory shall at
any time be entitled in respect of the Units, including, without limitation,
distributions in the ordinary course, distributions from sales of assets,
distributions upon liquidation, winding-up, or dissolution, payments in
settlement of existing or future litigation, and all other distributions and
payments from and after the Expiration Date, in respect of the Units tendered by
the Signatory and accepted for payment and thereby purchased by the Purchaser;
(ii) all other payments, if any, due or to become due to the Signatory in
respect of the Units, under or arising out of the agreement and certificate of
limited partnership of the Partnership (the "Partnership Agreement"), or any
agreement pursuant to which the Units were sold (the "Purchase Agreement"),
whether as contractual obligations, damages, insurance proceeds, condemnation
awards or otherwise; (iii) all of the Signatory's claims, rights, powers,
privileges, authority, options, security interests, liens and remedies, if any,
under or arising out of the Partnership Agreement or Purchase Agreement or the
Signatory's 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 the Partnership; and (iv) all present and
future claims, if any, of the Signatory against the Partnership, the other
partners of the Partnership, or the general partner and its affiliates, under or
arising out of the Partnership Agreement, the Purchase Agreement, the
Signatory's status as a limited partner, or the terms or conditions of the
Offer, for monies loaned or advanced, for services rendered, for the management
of the Partnership or otherwise.

     NOTWITHSTANDING ANY PROVISION IN THE PARTNERSHIP AGREEMENT OR ANY PURCHASE
AGREEMENT TO THE CONTRARY, THE SIGNATORY HEREBY AND THEREBY DIRECTS EACH GENERAL
PARTNER OF THE PARTNERSHIP TO MAKE ALL DISTRIBUTIONS AFTER THE PURCHASER ACCEPTS
THE TENDERED UNITS FOR PAYMENT TO THE PURCHASER OR ITS DESIGNEE. Subject to and
effective upon acceptance for payment of any Unit tendered hereby and thereby,
the Signatory hereby requests that the Purchaser be admitted to the Partnership
as a substitute limited partner under the terms of the Partnership Agreement.
Upon request, the Signatory will execute and deliver additional documents deemed
by the Information Agent or the Purchaser to be necessary or desirable to
complete the assignment, transfer and purchase of Units tendered hereby and
thereby and will hold any distributions received from the Partnership after the
Expiration Date in trust for the benefit of the Purchaser and, if necessary,
will promptly forward to the Purchaser any such distributions immediately upon
receipt. The Purchaser reserves the right to transfer or assign, in whole or in
part, from time to time, to one or more of its affiliates, the right to purchase
Units tendered pursuant to the Offer, but any such transfer or assignment will
not relieve the Purchaser of its obligations under the Offer or prejudice the
rights of tendering unitholders to receive payment for Units validly tendered
and accepted for payment pursuant to the Offer.

     By executing the enclosed Acknowledgment and Agreement, the Signatory
represents that either (i) the Signatory is not a plan subject to Title I of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"), or
an entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of any such plan, or (ii) the tender and acceptance of Units pursuant
to the Offer will not result in a nonexempt prohibited transaction under Section
406 of ERISA or Section 4975 of the Code.

     The Signatory understands that a tender of Units to the Purchaser will
constitute a binding



                                      II-2
<PAGE>   3

agreement between the Signatory and the Purchaser upon the terms and subject to
the conditions of the Offer. The Signatory recognizes that under certain
circumstances set forth in the Offer, the Purchaser may not be required to
accept for payment any or all of the Units tendered hereby. In such event, the
Signatory understands that any Acknowledgment and Agreement for Units not
accepted for payment may be returned to the Signatory or destroyed by the
Purchaser (or its agent). THIS TENDER IS IRREVOCABLE, EXCEPT THAT UNITS TENDERED
PURSUANT TO THE OFFER MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION DATE,
OR UNLESS ALREADY ACCEPTED FOR PAYMENT, ANY TIME AFTER 60 DAYS FROM THE OFFER
DATE.

     THE SIGNATORY HAS BEEN ADVISED THAT THE PURCHASER IS AN AFFILIATE OF THE
GENERAL PARTNER OF THE PARTNERSHIP AND NO SUCH GENERAL PARTNER MAKES ANY
RECOMMENDATION AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING UNITS IN THE
OFFER. THE SIGNATORY HAS MADE HIS OR HER OWN DECISION TO TENDER UNITS.

     The Signatory hereby and thereby represents and warrants for the benefit of
the Partnership and the Purchaser that the Signatory owns the Units tendered
hereby and thereby and has full power and authority and has taken all necessary
action to validly tender, sell, assign, transfer, convey and deliver the Units
tendered hereby and thereby and that when the same are accepted for payment by
the Purchaser, the Purchaser will acquire good, marketable and unencumbered
title thereto, free and clear of all liens, restrictions, charges, encumbrances,
conditional sales agreements or other obligations relating to the sale or
transfer thereof, and such Units will not be subject to any adverse claims and
that the transfer and assignment contemplated herein and therein are in
compliance with all applicable laws and regulations.

     All authority herein or therein conferred or agreed to be conferred shall
survive the death or incapacity of the Signatory, and any obligations of the
Signatory shall be binding upon the heirs, personal representatives, trustees in
bankruptcy, legal representatives, and successors and assigns of the Signatory.

     The Signatory represents and warrants that, to the extent a certificate
evidencing the Units tendered hereby and thereby (the "original certificate") is
not delivered by the Signatory together with the Acknowledgment and Agreement,
(i) the Signatory represents and warrants to the Purchaser that the Signatory
has not sold, transferred, conveyed, assigned, pledged, deposited or otherwise
disposed of any portion of the Units, (ii) the Signatory has caused a diligent
search of its records to be taken and has been unable to locate the original
certificate, (iii) if the Signatory shall find or recover the original
certificate evidencing the Units, the Signatory will immediately and without
consideration surrender it to the Purchaser; and (iv) the Signatory shall at all
times indemnify, defend, and save harmless the Purchaser and the Partnership,
its successors, and its assigns from and against any and all claims, actions,
and suits, whether groundless or otherwise, and from and against any and all
liabilities, losses, damages, judgments, costs, charges, counsel fees, and other
expenses of every nature and character by reason of honoring or refusing to
honor the original certificate when presented by or on behalf of a holder in due
course of a holder appearing to or believed by the Partnership to be such, or by
issuance or delivery of a replacement certificate, or the making of any payment,
delivery, or credit in respect of the original certificate without surrender
thereof, or in respect of the replacement certificate.

                                         appointment of successor trustee(s).

4.   TAX CERTIFICATIONS. The unitholder(s) tendering Units to the Purchaser
     pursuant to the Offer must furnish the Purchaser with the unitholder(s)'
     taxpayer identification number ("TIN") and certify as true, under penalties
     of perjury, the representations in Box 6 and Box 7 of the Acknowledgment
     and Agreement. By signing the Signature Box, the unitholder(s) certifies
     that the TIN as printed (or corrected) on Acknowledgment and Agreement in
     the box entitled "Description of Units Tendered" and the representations
     made in Box 6 and Box 7 of the Acknowledgment and Agreement are correct.
     See attached Guidelines for Certification of Taxpayer Identification Number
     on Substitute Form W-9 for guidance in determining the proper TIN to give
     the Purchaser.

     U.S. PERSONS. A unitholder that is a U.S. citizen or a resident alien
     individual, a domestic corporation, a domestic partnership, a domestic
     trust or a domestic estate (collectively, "U.S. Persons"), as those terms
     are defined in the Code, should follow the instructions below with respect
     to certifying Box 6 and Box 7 of the Acknowledgment and Agreement.

     BOX 6 - SUBSTITUTE FORM W-9.

     Part (i), Taxpayer Identification Number -- Tendering unitholders must
     certify to the Purchaser that the TIN as printed (or corrected) on the
     Acknowledgment and Agreement in the box entitled "Description of Units
     Tendered" is correct. If a correct TIN is not provided, penalties may be
     imposed by the Internal Revenue Service (the "IRS"), in addition to the
     unitholder being subject to backup withholding.

     Part (ii), Backup Withholding -- In order to avoid 31% Federal income tax
     backup withholding, the tendering unitholder must certify, under penalty of
     perjury, that such unitholder is not subject to backup withholding. Certain
     unitholders (including, among others, all corporations and certain exempt
     non-profit organizations) are not subject to backup withholding. Backup
     withholding is not an additional tax. If withholding results in an
     overpayment of taxes, a refund may be obtained from the IRS. When
     determining the TIN to be furnished, please refer to the following as a
     guide:

     Individual accounts - should reflect owner's TIN.
     Joint accounts - should reflect the TIN of the owner whose name appears
     first.
     Trust accounts - should reflect the TIN assigned to the trust.
     IRA custodial accounts - should reflect the TIN of the custodian (not
     necessary to provide).
     Custodial accounts for the benefit of minors - should reflect the TIN of
     the minor.
     Corporations, partnership or other business entities - should reflect the
     TIN assigned to that entity.

     By signing the Signature Box, the unitholder(s) certifies that the TIN as
     printed (or corrected) on the front of the Acknowledgment and Agreement is
     correct.

     BOX 7 - FIRPTA AFFIDAVIT -- Section 1445 of the Code requires that each
     unitholder transferring interests in a partnership with real estate assets
     meeting certain criteria certify under penalty of perjury the
     representations made in Box B, or be subject to withholding of tax equal to
     10% of the purchase price for interests purchased. Tax withheld under
     Section 1445 of the Code is not an additional tax. If withholding results
     in an overpayment of tax, a refund may be claimed from the IRS.



                                      II-5
<PAGE>   6

     FOREIGN PERSONS -- In order for a tendering unitholder who is a Foreign
     Person (i.e., not a U.S. Person, as defined above) to qualify as exempt
     from 31% backup withholding, such foreign unitholder must submit a
     statement, signed under penalties of perjury, attesting to that
     individual's exempt status. Forms for such statements can be obtained from
     the Information Agent.

5.   VALIDITY OF ACKNOWLEDGMENT AND AGREEMENT. All questions as to the validity,
     form, eligibility (including time of receipt) and acceptance of an
     Acknowledgment and Agreement and other required documents will be
     determined by the Purchaser and such determination will be final and
     binding. The Purchaser's interpretation of the terms and conditions of the
     Offer (including these Instructions for the Acknowledgment and Agreement)
     will be final and binding. The Purchaser will have the right to waive any
     irregularities or conditions as to the manner of tendering. Any
     irregularities in connection with tenders, unless waived, must be cured
     within such time as the Purchaser shall determine. The Acknowledgment and
     Agreement will not be valid until any irregularities have been cured or
     waived. Neither the Purchaser nor the Information Agent are under any duty
     to give notification of defects in an Acknowledgment and Agreement and will
     incur no liability for failure to give such notification.

6.   ASSIGNEE STATUS. Assignees must provide documentation to the Information
     Agent which demonstrates, to the satisfaction of the Purchaser, such
     person's status as an assignee.

7.   TRANSFER TAXES. The amount of any transfer taxes (whether imposed on the
     registered holder or such person) payable on account of the transfer to
     such person will be deducted from the purchase price unless satisfactory
     evidence of the payment of such taxes or exemption therefrom is submitted.

8.   SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If consideration is to be issued
     in the name of a person other than the person signing the Signature Box of
     the Acknowledgment and Agreement or if consideration is to be sent to
     someone other than such signer or to an address other than that set forth
     on the Acknowledgment and Agreement in the box entitled "Description of
     Units Tendered," the appropriate boxes on the Acknowledgment and Agreement
     must be completed.

YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND
RETURN IT TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE
DIVIDENDS, ALSO SIGN AND DATE THE FORM. IF YOU ARE A NONRESIDENT ALIEN OR A
FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH PAYER A COMPLETED
INTERNAL REVENUE FORM W-8 (CERTIFICATE OF FOREIGN STATUS).

     Certain payments other than interest, dividends, and patronage dividends,
that are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under sections 6041, 6041A(A),
6045, and 6050A of the Code.

     PRIVACY ACT NOTICE -- Section 6109 of the Code requires most recipients of
dividend, interest, or other payments to give correct taxpayer identification
numbers to payers who must report the payments to the IRS. The IRS uses the
numbers for identification purposes. Payers must be given the numbers whether or
not recipients are required to file a tax return. Payers must generally withhold
31% of taxable interest, dividend, and certain other payments to a payee who
does not furnish a correct taxpayer identification number to a payer. Certain
penalties may also apply.

    PENALTIES

     (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER -- If
you fail to furnish your correct taxpayer identification number to a payer, you
are subject to a penalty of $50 for each such failure unless your failure is due
to reasonable cause and not to willful neglect.

     (2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING -- If
you make a false statement with no reasonable basis that results in no
imposition of backup withholding, you are subject to a penalty of $500.

     (3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

     FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL
REVENUE SERVICE.

[ ] Under penalties of perjury, the Signatory certifies that: (1) the number
shown on this form is the unitholder's correct Taxpayer Identification No.
("TIN") or the unitholder has applied for a TIN; and (2) the unitholder is not
subject to backup withholding either because the unitholder: (a) is exempt for
backup withholding; (b) has not been notified by the Internal Revenue Service
("IRS") that the unitholder is subject to back-up withholding as a result of
failure to report all interest or dividends; or (c) has been notified by the IRS
that such unitholder is no longer subject to backup withholding.

Certification Instructions - You must cross out item (2) in the paragraph above
if you have been notified by the IRS that you are subject to back-up withholding
because of underreporting interest or dividends on your tax return. However, if
after being notified by the IRS that you were subject to back-up withholding you
received another notification from the IRS that you are no longer subject to
back-up withholding, do not cross out item (2).

Please check this box [ ] if the unitholder has applied for a TIN, a TIN has not
been issued to the unitholder, and either (a) the unitholder has mailed or
delivered an application to receive a TIN to the appropriate IRS Center or
Social Security Administration Office, or (b) the unitholder intends to mail or
deliver an application in the near future (it being understood that if the
unitholder does not provide a TIN to the Purchaser, 31% of all reportable
payments made to the unitholder will be withheld).

Section 1445(e)(5) of the Internal Revenue Code and Treas. Reg.1.1445-11T(d)
provide that a transferee of the U.S. real property interest must withhold tax
equal to 10% of the amount realized if the transferor is a foreign person. To
inform the Purchaser that withholding of tax is not required upon this
disposition of a U.S. real property interest, the undersigned hereby certifies
the following under penalties of perjury: (i) the unitholder, if an individual,
is a U.S. citizen or a resident alien for purposes of U.S. income taxation, and
if other than an individual, is not a foreign corporation, foreign partnership,
foreign estate or foreign trust (as those terms are defined in the Internal
Revenue Code and Income Tax Regulations); (ii) the unitholder's U.S. social
security number (for individuals) or employer identification number (for
non-individuals) is correct as furnished in the blank provided for that purpose
on the front of this Acknowledgment and Agreement; and (iii) the unitholder's
home address (for individuals), or office address (for non-individuals), is
correctly printed (or corrected) on the front of this Acknowledgment and
Agreement. The person signing this Acknowledgment and Agreement understands
that this certification may be disclosed to the IRS by the Purchaser and that
any false statements contained herein could be punished by fine, imprisonment,
or both.

[ ] Please check this box if the withholding of tax is required because the
unitholder does not satisfy all of the above conditions.
================================================================================

     ACKNOWLEDGMENT AND AGREEMENT. The signatory hereto (the "Signatory") hereby
acknowledges that he or she has received and reviewed (i) the Purchaser's Offer
to Purchase, dated the Offer Date (as supplemented or amended from time to time,
the "Offer to Purchase") relating to the offer by AIMCO Properties, L.P. (the
"Purchaser") to purchase limited partnership interests in the Partnership, (ii)
the Letter of Transmittal attached as Annex III thereto (the "Letter of
Transmittal"), (iii) this Acknowledgment and Agreement, and (iv) the
Instructions hereto in the Letter of Transmittal, as each may be supplemented or
amended from time to time, and whose terms and conditions are incorporated by
reference herein (collectively, the "Offer"). Capitalized terms used herein but
not otherwise defined herein shall have the meanings ascribed thereto in the
Offer to Purchase. The Signatory hereby understands and agrees that the Letter
of Transmittal is hereby incorporated by reference herein and is hereby made a
part hereof.

     The Signatory hereby makes the representations, warranties, and covenants,
and agrees to the terms and conditions, in each case set forth in the Letter of
Transmittal, and hereby tenders to the Purchaser the units set forth in the box
entitled "Description of Units Tendered" herein, including all interests in any
limited partnership represented by such units (collectively, the "Units"), on
the terms and conditions set forth in the Offer, and certifies under penalties
of perjury that the statements in Box 6 and Box 7 herein are true.

     The Signatory hereby irrevocably constitutes and appoints the Purchaser and
any designees of the Purchaser as the true and lawful agent and attorney-in-fact
of the Signatory with respect to such Units, with full power of substitution
(such power of attorney being deemed to be an irrevocable power coupled with an
interest), to vote or act in such manner as any such attorney and proxy or
substitute shall, in its sole discretion, deem proper with respect to such Units
on any matter submitted for the consent or approval of holders of such Units, to
do all such acts and things necessary or expedient to deliver such Units and
transfer ownership of such Units on the partnership books maintained by the
general partner of the Partnership, together with all accompanying evidence of
transfer and authenticity to, or upon the order of, the Purchaser, to sign any
and all documents necessary to authorize the transfer of the Units to the
Purchaser including, without limitation, the "Transferor's (Seller's)
Application for Transfer" created by the National Association of Securities
Dealers, Inc., if required, and upon receipt by the Information Agent (as the
Signatory's agent) of the offer price pursuant to the terms of the Offer, to
become a substitute limited partner, to receive any and all distributions made
by the Partnership to which the Purchaser is entitled pursuant to the terms of
the Offer (regardless of the record date for any such distribution), and to
receive all benefits and otherwise exercise all rights of beneficial ownership
of such Units, all in accordance with the terms of the Offer. This appointment
shall be effective upon the purchase of the Units by the Purchaser as provided
in the Offer and shall be irrevocable for a period of the lesser of (i) five
years following the termination of the Offer, or (ii) the maximum period
permitted by applicable law. Upon the purchase of Units pursuant to the Offer,
all prior proxies and consents given by the Signatory with respect to such Units
will be revoked and no subsequent proxies or consents may be given (and if given
will not be deemed effective).

     In addition to and without limiting the generality of the foregoing, the
Signatory hereby irrevocably (i) requests and authorizes (subject to and
effective upon acceptance for payment of any Unit tendered hereby) the
Partnership and its general partners to take any and all actions as may be
required to effect the transfer of the Units to the Purchaser (or its designee)
and to admit the Purchaser as a substitute limited partner in the Partnership
under the terms of the certificate and agreement of partnership of the
Partnership; (ii) empowers the Purchaser and its agent to execute and deliver to
each general partner a change of address form instructing the general partner to
send any and all future distributions to the address specified in the form, and
to endorse any check payable to or upon the order of such unitholder
representing a distribution to which the Purchaser is entitled pursuant to the
terms of the Offer, in each case in the name and on behalf of the tendering
unitholder; (iii) agrees not to exercise any rights pertaining to the Units
without the prior consent of the Purchaser; and (iv) requests and consents to
the transfer of the Units, to be effective on the books and records of the
Partnership as of the effective date set forth in the Offer.

     In addition, the Signatory irrevocably constitutes and appoints the
Purchaser and any designees of the Purchaser as the true and lawful agent and
attorney-in-fact of the Signatory with respect to such Units, with full power of
substitution (such power of



                                       3

attorney being deemed to be an irrevocable power coupled with an interest), to
withdraw any or all of such Units that have been previously tendered in response
to any tender or exchange offer provided that the price per unit being offered
by the Purchaser is equal to or higher than the price per unit being offered in
the other tender or exchange offer. This appointment is effective immediately
and shall continue to be effective unless and until such Units are withdrawn
from the offer by the Signatory prior to the expiration date (as defined in the
Offer to Purchase).

     All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the Signatory, and any obligations of the Signatory shall
be binding upon the heirs, personal representatives, trustees in bankruptcy,
legal representatives, and successors and assigns of the Signatory.

Dear Limited Partner:

         We are pleased to announce that we are offering to purchase units in
your partnership, Winthrop Growth Investors 1 Limited Partnership, for $496 per
unit, pursuant to the enclosed Offer to Purchase. Our offer presents you with
the following two options, which you are free to accept or reject in any
combination you like:

                  1. You may tender each of your units in exchange for $496 in
         cash, in which case you may recognize a gain or loss for federal income
         tax purposes.

                  2. You may retain any or all of your units. If you choose to
         retain any or all of your units, your rights as a holder of units will
         remain unchanged. You will continue to participate in gains and losses
         of your partnership(s), and you will receive distributions, if any,
         payable in respect of your units.

         The offer is scheduled to expire on June 13, 2000, unless otherwise
extended.

          We are offering to purchase any and all units in your partnership,
subject to the terms of the offer. Our offer is not subject to any minimum
number of units being tendered. You will not be required to pay any partnership
transfer fees in connection with any disposition of your units pursuant to our
offer. Our offer price will be reduced for any distributions subsequently made
by your partnership prior to the expiration of our offer.

         There are advantages and disadvantages to you of accepting or declining
our

offer. The terms of the offer are more fully described in the enclosed
materials, which you should read carefully. These documents describe the
material risks and opportunities associated with the offer, including certain
tax considerations. The general partner of your partnership is remaining neutral
and makes no recommendation as to whether you should tender or refrain from
tendering your units in any offer. Although the general partner believes our
offer is fair, the general partner also believes that you must make your own
decision whether or not to participate in any offer, based upon a number of
factors, including several factors that may be personal to you, such as your
financial position, your need or desire for liquidity, your preferences
regarding the timing of when you might wish to sell your units, other financial
opportunities available to you, and your tax position and the tax consequences
to you of selling your units. The general partner is our affiliate. LIMITED
PARTNERS ARE URGED TO READ OUR OFFER TO PURCHASE AND THE RELATED MATERIALS
CAREFULLY AND IN THEIR ENTIRETY BEFORE DECIDING WHETHER TO TENDER THEIR UNITS.

         You should be aware, however, that, as with any rational investment
decision, we are making our offer with a view to making a profit.

         If you desire to tender any of your units in response to our offer, you
should complete and sign the enclosed yellow acknowledgment and agreement in
accordance with the enclosed instructions and mail or deliver the signed yellow
acknowledgment and agreement and any other required documents to River Oaks
Partnership Services, Inc., which is acting as the Information Agent in
connection with our offer, at the address set forth on the back cover of the
enclosed Offer to Purchase. The offer will expire at 5:00 p.m. New York City
time on June 13, 2000, unless extended. If you have any questions or require
further information, please call the Information Agent, toll free, at (888)
349-2005.


                                   Very truly yours,


                                   AIMCO PROPERTIES, L.P.
