                           OFFER TO PURCHASE FOR CASH
                             AIMCO Properties, L.P.
is offering to purchase up to 12,498.55 units of limited partnership interest in

                               Angeles Partners XI

                            for $110 per unit in CASH

We will only accept a maximum of 12,498.55 units in response to our offer. If
more units are tendered to us, we will generally accept units on a pro rata
basis according to the number of units tendered by each person.

We will pay for accepted units promptly after expiration of the offer.

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

Our offer and your withdrawal rights will expire at 5:00 p.m., New York City
time, on September 16, 1999, unless we extend the deadline.

YOU WILL NOT PAY ANY PARTNERSHIP TRANSFER FEES IF YOU TENDER YOUR UNITS.

Our offer is subject to a minimum of 35% of the units tendered.

         SEE "RISK FACTORS" BEGINNING ON PAGE 1 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 $110 per unit without any
                  arms-length negotiations. Accordingly, our offer price may not
                  reflect the fair market value of your units.

         o        As of June 30, 1998, your general partner (which is our
                  subsidiary) estimated the net asset value of your units to be
                  $229 per unit and an affiliate of your general partner
                  estimated the net liquidation value of your units to be
                  $207.88 per unit.

         o        While secondary sales activity in the units of your
                  partnership has been limited and sporadic, sales prices of
                  units in your partnership ranged from $1 to $155 since January
                  1, 1996.

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

                                                        (continued on next page)

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

         If you desire accept our offer, you should complete and sign the letter
of transmittal in accordance with the instructions thereto and mail or deliver
the signed letter of transmittal and any other required documents 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. 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        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.

         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 subsequent 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
                  but not limited to the removal of the general partner, most
                  amendments to the partnership agreement and the sale of all or
                  substantially all of your partnership's assets.

                                  INTRODUCTION

         We are offering to purchase up to 12,498.55 units, representing
approximately 31.54% of the outstanding units of limited partnership interest in
your partnership, for the purchase price of $110 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.

         If you tender your units in response to our offer you will not be
obligated to pay any partnership transfer fees but will be obligated to pay any
transfer taxes (see Instruction 8 to the letter of transmittal). 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 conditioned on a
minimum of 35% of the units being tendered. In addition, certain other
conditions apply. See "The Offer -- Section 17." 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 September
16, 1999, 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 October 19, 1999.

         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 June 30, 1999, AIMCO owned or managed 269,404
apartment units in 2,037 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."

         As a result of our October 1, 1998 merger with Insignia Financial
Group, Inc. and our February 26, 1999 merger with Insignia Properties Trust, we
acquired a 100% ownership interest in the general partner of your partnership
and the company that manages the residential property owned by your partnership.

                                  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 property 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.



                                       1
<PAGE>   5


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 property.

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 the direct capitalization method to estimate the value of your
partnership's property because we think a prospective purchaser of the property
would value the property using this method. In doing so, we applied a
capitalization rate to your partnership's property income for the year ended
December 31, 1998. 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. Thus, our offer does not satisfy any expectation that you would receive
the return of your investment in the partnership through a sale of any property.
It is not known when the property owned by your partnership may be sold. There
may be no way to liquidate your investment in the partnership in the future
until the property is 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 property sale would not be advantageous given market conditions,
the condition of the property and tax considerations. In particular, the general
partner considered the changes in the local rental market, the potential for
appreciation in the value of the property and the tax consequences to you and
your partners on a sale of the property. We cannot predict when the property
will be sold or otherwise disposed of.

HOLDING UNITS MAY RESULT IN GREATER FUTURE VALUE

         You might receive more value if you retain your units until your
partnership is liquidated.



                                       2
<PAGE>   6

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 your financial position, your need or desire for liquidity, 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 our subsidiaries receive fees for managing your partnership and
its residential property, 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 SUBSEQUENT OFFER AT A HIGHER PRICE

         It is possible that we may conduct a subsequent 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 of your
partnership 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 your units of limited partnership
interest of your partnership 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 of limited partnership interest of your partnership. 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
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
property owned by your partnership.



                                       3
<PAGE>   7


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 all the units 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.

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 of limited partnership and the liabilities of your
partnership were to be reduced, you will 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.

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
rendered units until the expiration of the offer and acceptance of units for
payment.


                                    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) up to 12,498.55 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." For purposes of the offer, the
term "expiration date" shall mean 5:00 p.m., New York City time, on September
16, 1999, 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" 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.


                                       4
<PAGE>   8

         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 more than 12,498.55 units are validly tendered prior to the
expiration date and not properly withdrawn prior to the expiration date in
accordance with the procedures specified in Section 4, we will, upon the terms
and subject to the conditions of the offer, accept for payment and pay for an
aggregate of 12,498.55 of the units so tendered, 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 12,498.55 units, 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 Securities Exchange Act of 1934 (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.

         The offer is conditioned on satisfaction of certain conditions. THE
OFFER IS CONDITIONED UPON A MINIMUM OF 35% OF THE UNITS BEING TENDERED. See "The
Offer -- Section 17," which sets 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 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 May 1, 1999.

         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 August 19, 1999.

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, up to 12,498.55 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." UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN
MAKING SUCH PAYMENT.



                                       5
<PAGE>   9

         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 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. 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, then, without prejudice to our rights under "The Offer --
Section 17," the Information Agent may, nevertheless, on our behalf retain
tendered units, and those units may not be withdrawn except to the extent that
the tendering limited partners are entitled to withdrawal rights as described in
"The Offer -- Section 4"; 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


                                       6
<PAGE>   10

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 for 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 enable the units
tendered to be voted in accordance with out directions. The proxy and power of
attorney granted by you to us upon your execution of the letter of transmittal
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 managers and 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. You
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
managers and 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.

         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


                                       7
<PAGE>   11

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. 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."

         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."

         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 or on or after October 19, 1999, 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."


                                       8
<PAGE>   12

         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 shall 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.

         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 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 failure to satisfy such conditions, (iii) upon the occurrence of any of the
conditions specified in "The Offer - Section 17," 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 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 will
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"; subject, however, to
our obligation, pursuant to Rule 14e-l(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. 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.

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


                                       9
<PAGE>   13

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 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 United States 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.


                                       10
<PAGE>   14

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.

         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 offset 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


                                       11
<PAGE>   15

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 United States 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 done or in combinations with other transfers of interests
in your partnership could result in such a termination of your partnership. If
your partnership is deemed to terminate for tax purposes, the following United
States 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.

         A remaining limited partner will not generally recognize any gain or
loss upon the deemed distribution or upon the deemed contribution and the
capital accounts of the remaining limited partners in the old partnership will
carry over intact into the new partnership. A termination may change (and
possibly shorten) a remaining partner's holding period with respect to its
retained units in your partnership for United States federal income tax
purposes.

         The new partnership's adjusted tax basis in its assets will be the same
as the old partnership's basis in such assets immediately before the
termination. A termination may also subject the assets of the new partnership to
depreciable lives in excess of those currently applicable to the old
partnership. This would generally decrease the annual average depreciation
deductions allocable to the remaining limited partners for a number of years
following consummation of the offer (thereby increasing the taxable income
allocable to their units in each such year), but would have no effect on the
total depreciation deductions available over the useful lives of the assets of
your partnership.

         Elections as to certain tax matters previously made by the old
partnership prior to termination will not be applicable to the new partnership
unless the new partnership chooses to make the same elections.

         Additionally, upon a termination for tax purposes, the old
partnership's taxable year will close for all limited partners. In the case of a
remaining limited partner or a partially tendering limited partner reporting on
a tax year other than a calendar year, the closing of the partnership's taxable
year may result in more than 12 months' taxable income or loss of the old
partnership being includible in such limited partner's taxable income for the
year of termination.

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 20.09% of the units
pursuant to the offer, we will own in excess of 50% of the total outstanding
units and, as a result, 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, however, because we currently own approximately
29.91% of the outstanding limited partnership 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 property 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 property 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 your partnership, the business and property 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 property.

         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 expected to result in a reduction in the liquidity and
volume of activity in the trading market for the security. In this case,
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. Because the units are widely-held, however, we believe
that, even if we purchase the maximum number of units in the offer, the units
will be held of record by more than 300 persons.

SECTION 9. BACKGROUND AND REASONS FOR THE OFFER.

         GENERAL. We are in the business of acquiring direct and indirect

partnership. Our offer provides us with an opportunity to increase our ownership
interest in your partnership's property while providing you and other investors
with an opportunity to liquidate your current investment.


                                       14

         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"). The general partner of your
partnership is a wholly owned subsidiary of IPT. Through the Insignia Merger,
AIMCO also acquired a majority ownership interest in the entity that manages the
residential property 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 (the "IPT Merger").
Together with its subsidiaries, AIMCO currently owns, in the aggregate,
approximately 29.91% of the outstanding limited partnership units of your
partnership.

         One of the reasons we chose to acquire Insignia is that we would be
able to make the tender offers to acquire 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. As of the
date of this offering, AIMCO Properties, L.P. proposes to make offers to
approximately 90 of the Insignia Partnerships, including your partnership.

         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 in the Insignia Partnerships. 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 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. We determined in June
of 1998 that if the merger with Insignia were consummated, we would offer to
limited partners of certain of the Insignia Partnerships limited partnership
units of AIMCO Properties, L.P. and/or cash.

         PRIOR TENDER OFFERS. Prior to the Insignia Merger, a number of tender
offers had been made to acquire units of your partnership. On August 12, 1998,
Cooper River Properties, L.L.C., then an affiliate of Insignia and now our
affiliate, commenced a tender offer pursuant to which it acquired 8,782 units
(representing approximately 22.162% of the number outstanding) at a cash
purchase price of $150 per unit. On May 13, 1999, we commenced a tender offer
for $77 per unit. A total of 730 units, representing 1.8% of the outstanding
units, was validly tendered pursuant to the offer.

         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. 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.

         CERTAIN LITIGATION. On March 24, 1998, certain persons claiming to own
limited partner interests in certain of the limited partnerships for which our
subsidiaries act as general partner (including your partnership) filed a
purported class and derivative action in California Superior Court in the County
of San Mateo against AIMCO, Insignia, the general partners of the partnerships,
certain persons and entities who purportedly formerly controlled the general
partners, and additional entities affiliated with and individuals who are
officers, directors


                                       15

and/or principals of several of the defendants. The complaint contains
allegations that, among other things, (i) the defendants breached fiduciary
duties owed to the plaintiffs, or aided and abetted in those purported breaches,
by selling or agreeing to sell their "fiduciary positions" as stockholders,
officers and directors of the general partners for a profit and retaining said
profit rather than distributing it to the plaintiffs; (ii) the defendants
breached fiduciary duties, or aided and abetted in those purported breaches, by
mismanaging the partnerships and misappropriating assets of the partnerships by
(a) manipulating the operations of the partnerships to depress the trading price
of limited partnership units of the partnerships; (b) coercing and fraudulently
inducing unitholders to sell units to certain of the defendants at depressed
prices; and (c) using the voting control obtained by purchasing units at
depressed prices to entrench certain of the defendants' positions of control
over the partnerships; and (iii) the defendants breached their fiduciary duties
to the plaintiffs by (a) selling assets of the partnerships such as mailing
lists of unitholders and (b) causing the general partners to enter into
exclusive arrangements with their affiliates to sell goods and services to the
general partners, the unitholders and tenants of properties owned by the
partnerships. The complaint also alleges that the foregoing allegations
constitute violations of various California securities, corporate and
partnership statutes, as well as conversion and common law fraud. The complaint
seeks unspecified compensatory and punitive damages, an injunction blocking the
sale of control of the general partners and a court order directing the
defendants to discharge their fiduciary duties to the plaintiffs. On June 25,
1998, the defendants filed motions seeking dismissal of the action. In lieu of
responding to the motion, plaintiffs have filed an amended complaint. On October
14, 1998, the AIMCO and Insignia defendants filed demurrers to the amended
complaint. The demurrers (which are requests to dismiss the action as a matter
of law) were heard on February 8, 1999, but no decision has been reached by the
Court. While no assurances can be given, we believe that the ultimate outcome of
this litigation will not have a material adverse effect on us.

         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
real estate assets of your partnership in a private transaction, and the
proceeds realized from any such sale would be uncertain. Liquidation of the
partnership assets may trigger a substantial prepayment penalty under the
mortgage for the property. Your general partner believes it currently is in the
best interest of your partnership to continue holding its real estate assets.
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 property may be sold. See "The Offer - Section 13.
Certain Information Concerning Your Partnership - Investment Objectives and
Policies; Sale or Financing of Investments."


                                       16
<PAGE>   20

         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, 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 property 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
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 would 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 property owned by your partnership.

         SALE OF ASSETS

         Your partnership could sell the property 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 liquidating distributions, 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 your partnership's property 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
property, 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 property, 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, 1998; (iii) unaudited results of
operations of the partnership's property for the period since the beginning of
the partnership's current fiscal year and to date in 1999; (iv) the operating
budget prepared by the residential property manager with respect to the
partnership's property for the year ending December 31, 1999; and (v) tender
offer statements, solicitation/recommendation statements and beneficial
ownership reports on Schedules 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.



                                       17
<PAGE>   21

         VALUATION OF UNITS. We determined our offer price by estimating the
value of each property owned by your partnership using the direct capitalization
method. This method involves applying a capitalization rate to your
partnership's annual 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 fiscal year ended December 31, 1998. 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 mortgage debt that the property is subject to 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, 1998, to your partnership's net operating income for the same
period.

<S>                                          <C>

</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 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 divided the fiscal 1998
         property income of $3,931,000 by the property's capitalization rate of
         10.86% to derive an estimated gross property value of $36,189,443.


                                       18
<PAGE>   22

o        Second, we calculated the value of the equity of your partnership by
         adding to the aggregate gross property value of the property 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 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
         $4,403,000. 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, 99% 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.

</TABLE>

         COMPARISON OF CONSIDERATION TO ALTERNATIVE CONSIDERATION. To assist
holders of units in evaluating the offer, your general partner (which is our
subsidiary) has attempted to compare the offer price against: (a) prices at
which the units have sold in the secondary market; (b) estimates of the value of
the units on a liquidation basis; (c) your general partner's estimate of net
asset value; (d) an affiliate's estimate of net liquidation value; and (e) the
recent appraisal of your partnership's property. 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.

         The results of these comparative analyses are summarized in the
following chart. You should bear in mind that the estimated values assigned to
the alternate forms of consideration are based on a variety of assumptions that
have been made by us. These assumptions relate to, among other things, the
operating results, if


                                       19
<PAGE>   23

any, since March 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 subsidiary) 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 property 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, 2035, 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.

         PRIOR TENDER OFFER

         On May 13, 1999, we commenced a tender offer for $77 per unit. A total
of 730 units, representing 1.8% of the outstanding units, was validly tendered
pursuant to the offer.

         PRICES ON SECONDARY MARKET

         Secondary market sales information is not a reliable measure of value
because of the lack 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.

         Although the general partner requests and sometimes receives
information on the prices at which units are sold, it does not regularly receive
or maintain information regarding the bid or asked quotations of secondary
market makers, if any. The prices in the table below are based solely on
information provided to the general partner by sellers and buyers of units
transferred in sale transactions (i.e., excluding transactions believed to
result from the death of a limited partner, rollover to an IRA account,
establishment of a trust, trustee to trustee



                                       20
<PAGE>   24

transfers, termination of a benefit plan, distributions from a qualified or
nonqualified plan, uniform gifts to minors, abandonment of units or similar
non-sale transactions). The transfer paperwork submitted to the general partner
often does not include the requested price information or contains conflicting
information as to the actual sales price. Sale prices not reported or disclosed
could exceed the reported prices. According to information obtained from your
general partner (which is our subsidiary) from January 1, 1996 to September 30,
1998, an aggregate of 3,054 units (representing approximately 7.7% of the total
outstanding units) were transferred (including any tender offers) in sale
transactions. Set forth in the table below are the high and low sales prices of
units for the quarterly periods from January 1, 1996 to September 30, 1998, as
reported by your general partner:

         APPRAISAL

         Your partnership's property was appraised in 1996 by an independent
third party appraiser, Koeppel Tener Real Estate Services, Inc. (the
"Appraiser"), in connection with a requirement in your partnership's agreement
of limited partnership and not in connection with the offer. According to the
appraisal report, the scope of the appraisals included an inspection of the
properties and an analysis of the surrounding market. The Appraiser relied
principally on the income capitalization approach to valuation and secondarily
on the sales comparison approach, and represented that its report was prepared
in accordance with the Code of Professional Ethics and Standards of Professional
Appraisal Practice of the Appraisal Institute and the Uniform Standards of
Professional Appraisal Practice, and in compliance with the Appraisal Standards
set forth in the Financial Institutions Reform, Recovery and Enforcement Act of
1989 (known as "FIRREA"). The estimated market value of the fee simple estate of
the property specified in the report was $32,600,000, which is lower than our
estimated gross valuation of your partnership property of $36,189,443.

         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 also assumed that your
partnership's property was sold to an independent third-party buyer at the
current property value and that other balance sheet assets (excluding amortizing
assets) and liabilities of your partnership were sold at their book value, and
that the net proceeds of sale were allocated 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 relatively
fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets. However, for
simplification purposes, the sales of the assets are assumed to occur
concurrently. The liquidation analysis assumes that the assets would be disposed
of in an orderly manner and not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.

         GENERAL PARTNER'S ANNUAL ESTIMATES OF NET ASSET VALUE

         Your general partner (which is our subsidiary) prepared an estimate of
your partnership's net asset value per unit in connection with an offer to
purchase up to 4.9% of the outstanding units commenced by an unaffiliated party
in August 1998. That estimate of your partnership's net asset value per unit as
of June 30, 1998 was $229. This estimated net asset value is based on a
hypothetical sale of the partnership's properties and the distribution to the
limited partners and the general partner of the gross proceeds of such sales,
net of related indebtedness, together with the cash, proceeds from temporary
investments, and all other assets that are believed to have liquidation value,
after provision in full for all of the other known liabilities of your
partnership. This net asset value does not take into account (i) timing
considerations, (ii) costs associated with winding up the partnership, or (iii)
the $1,885,974 in deferred maintenance costs. Therefore, we believe that this
estimate of net asset value per unit does not necessarily represent either the
fair market value of a unit or the amount a limited partner reasonably could
expect to receive if the partnership's properties were sold and the partnership
was liquidated. For this reason, we considered this net asset value estimate to
be less meaningful in determining the offer price than the analysis described
above.

         AFFILIATE'S ESTIMATE OF NET LIQUIDATION VALUE

         An affiliate of your general partner which is now an affiliate of ours,
prepared an estimate of your partnership's net liquidation value per unit in
connection with a tender offer to purchase units for $150 each which closed in
September 1998. That estimate of your partnership's net liquidation value per
unit as of June 30, 1998 was $207.88. This estimated net liquidation value is
based on the income capitalization approach similar to the one we used, adjusted
for your partnership's other assets and liabilities (excluding prepaid and
deferred expenses and security deposits). Four percent was then deducted from
the resulting amount to cover the estimated costs of selling the property. This
final amount was then divided by the number of units outstanding to obtain the
$207.88 per unit. While this value is higher than our offer price per unit,
because different income and capitalization rates were used and we believe that
the income capitalization amounts used overstate the value of the property.
Further, such amount did not take in account (i) timing considerations, (ii)
costs associated with winding up the partnership, or (iii) the $1,885,974 in
deferred maintenance costs.

         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 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        Our offer price, and the method we used to determine our offer
                  price.


                                       23
<PAGE>   27

         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 refinancing, or a liquidation of the
                  partnership.

         o        An evaluation of the financial condition and results of
                  operations of your partnership including the increase in
                  property income of your partnership from a net loss of
                  $973,000 for the year ended December 31, 1997 to net income of
                  $19,000 for the year ended December 31, 1998.

         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 your financial position, your need or desire for liquidity, other
financial opportunities available to you, and your tax position and the tax
consequences to you of selling your units.

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. It also has a duty to remove the property manager for your
partnership's residential property, under certain circumstances, even though the
property manager is also an affiliate of AIMCO. The conflicts of interest
include: (1) the fact that a decision to remove, for any reason, the general
partner of your partnership from its current position as a general partner of
your partnership would result in a decrease or elimination of the substantial
management fees paid to an affiliate of the general partner of your partnership
for managing your partnership property; and (2) as a consequence of our
ownership of units, because 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. See "Risk Factors -- Conflicts of Interest
With Respect to the Offer." Your general partner has filed a
Solicitation/Recommendation Statement on Schedule 14D-9 with the SEC, which
indicates that it is remaining neutral and 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 AND THE SCHEDULE 14D-9
AND THE RELATED MATERIALS CAREFULLY AND IN THEIR 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 manager of your
partnership's residential property. The general partner of your partnership
received total fees and reimbursements of $148,000 in 1996, $145,000 in 1997 and
$142,000 in 1998. The reimbursement amount to your general partner for the 1998
fiscal year included $13,000 which was


                                       24
<PAGE>   28

paid to an affiliate of your general partner for costs incurred in connection
with construction oversight services. The residential property manager received
management fees of $346,000 in 1996, $352,000 in 1997 and $376,000 in 1998. We
have no current intention of changing the fee structure for your general partner
or the manager of your partnership's residential property.

         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 property is 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 such 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. 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 property. We currently intend that, upon consummation of the offer,
your partnership will continue its business and operations substantially as they
are currently being conducted. The offer is not expected to have any effect on
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. See "The Offer - Section 9." Any acquisition may be at a price higher
or lower than the price to be paid for the units purchased pursuant to this
offer, 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 property, 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 or any of
your partnership's subsidiaries; a sale or transfer of a material amount of your
partnership's assets (or assets of the partnership's subsidiaries); any changes
in composition of your partnership's senior management or personnel or their
compensation; any changes in your partnership's present capitalization 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 property. If any such loans are made,
upon default of such loans, the lender 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.



                                       25
<PAGE>   29

         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 29.91% of the outstanding 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. Angeles Partners XI was organized on February 14, 1983 under
the laws of the State of California. 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 one
residential apartment complex, Fox Run Apartments, a 776-unit complex in
Plainsboro, New Jersey.

         The general partner of your partnership is Angeles Realty Corporation
II, which is a wholly owned subsidiary of AIMCO. A wholly owned subsidiary of
AIMCO serves as manager of the residential property owned by your partnership.
As of December 31, 1998, there were 39,627 units issued and outstanding, which
were held of record by 2,949 limited partners. Your partnership's principal
executive offices are located at 1873 South Bellaire Street, 17th Floor, 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 which was sent to you prior to this
offer to purchase, 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 property by considering various factors, such as the
partnership's financial position and real estate and capital markets conditions.
The general partner monitors the property's 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
the 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 properties could improve over
time, making a sale of the partnership's property 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 property primarily because it expects the
property's operating performance to improve in the near term. In making this
assessment, your general partner noted that occupancy and rental rates at the
property were 97% and $2,192/unit, respectively, at December 31, 1998, compared
to 96% and $9,212/unit, respectively, at December 31, 1997. In particular, the
general partner noted that it expects to spend approximately $2,192,000 for
capital improvements at the property in 1999 to repair and update the property's
roof, landscape, irrigation and parking lot. 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 property at the present time would adequately reflect
the property's future prospects. Another significant factor considered by your
general partner is the likely tax consequences of a sale of the property 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 property.

         Under your partnership's agreement of limited partnership, the term of
the partnership will continue until December 31, 2035, 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.

         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 estimated to
be $2,192,000 for 1999, are expected to be paid 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 property. 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 property and the rents that may be charged
for such apartments. While we are 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 then
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.

         PROPERTY MANAGEMENT. Your partnership's residential property is managed
by an entity which is a wholly owned subsidiary of AIMCO. Pursuant to the
management agreement between the property manager and your partnership, the
property manager operates your partnership's residential property, establishes
rental policies and rates and directs marketing activities. The property manager
also is responsible for maintenance, the purchase of equipment and supplies, and
the selection and engagement of all vendors, suppliers and independent
contractors.

         DISTRIBUTIONS. Your partnership has paid no distributions during the
five years ended December 31, 1998.

         OPERATING BUDGET OF THE PARTNERSHIP. A summary of the operating budget
of your partnership's property for the year ending on December 31, 1999 is as
follows:

                          FISCAL 1999 OPERATING BUDGET

                                             ===========
</TABLE>

         The above budget at the time it was made was forward-looking
information developed by your general partner (which is our subsidiary).
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



                                       29
<PAGE>   33

limited to, lease revenue (including occupancy rates), various operating
expenses, general and administrative expenses, depreciation expenses, capital
expenditures, and working capital levels. While we 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 circumstances 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 1999 should not necessarily be considered as indicative of
what the audited operating results for fiscal 1999 will be. For the year ended
December 31, 1998, the partnership reported revenues of $8,028,000 and operating
expenses of $2,558,000.

         BENEFICIAL OWNERSHIP OF INTERESTS IN YOUR PARTNERSHIP. Together with
our subsidiaries, we currently own, in the aggregate, approximately 29.91% of
the outstanding limited partnership units of your partnership. 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) have
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
your general partner and its affiliates on a historical basis, and on a pro
forma basis assuming that all of the units sought in our offer had been acquired
at the beginning of each period:

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

         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

information on the public reference rooms. Your partnership's SEC filings are

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 all the units 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 $1,374,841 will be required to purchase
all of the 12,498.55 limited partnership units that we are seeking in this offer
(exclusive of fees and expenses estimated to be $12,000). For more information
regarding fees and expenses, see "The Offer - Section 19. Fees and Expenses" in
the Offer to Purchase.

         In addition to this offer, we are concurrently making offers to acquire
interests in approximately 100 other limited partnerships. If all such offers
were fully subscribed for cash, we would be required to pay approximately $260
million for all such units. If for some reason we did not have such funds
available we might extend this offer 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. Also, in some offers, investors have been offered a choice of
cash or securities. As a result, we expect that the funds that will be necessary
to consummate all the offers will be substantially less than $200 million. We
believe that we have sufficient cash on hand and available sources of financing
to pay such amounts. As of March 31, 1999, we had $38,000,000 of cash on hand
and $145,000,000 available for borrowing under our existing lines of credit.

         Under our secured $300 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 1.7 to 1.0 through September 31, 1999 and 1.75
to 1.0 thereafter. 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 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 14D-1 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 in this Section 19, 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, 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 its 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 Commission a Tender Offer Statement on Schedule
14D-1, 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. The Schedule 14D-1 and any amendments thereto,
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" under
"Additional Information Concerning Your Partnership."

    Upon the terms and subject to the conditions set forth in the Offer to
Purchase, and this Letter of Transmittal, the undersigned hereby tenders to the
Purchaser the Units set forth in the box above entitled "Description of Units

undersigned in cash, without interest.

    Subject to and effective upon acceptance for payment of any of the Units
tendered hereby in accordance with the terms of the Offer, the undersigned
hereby 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 that are accepted for payment pursuant to the Offer, including,
without limitation, (i) all of the undersigned's interest in the capital of the

in respect of the Units; (ii) all other payments, if any, due or to become due
to the undersigned in respect of the Units, under or arising out of the
agreement of limited partnership of the Partnership (the "Partnership
Agreement"), or any agreement pursuant to which the Units were sold (the

proceeds, condemnation awards or otherwise; (iii) all of the undersigned's
claims, rights, powers, privileges, authority, options, security interests,
liens and remedies, if any, under or arising out of the Partnership Agreement or

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 Offer Date.

    NOTWITHSTANDING ANY PROVISION IN A PARTNERSHIP AGREEMENT OR ANY PURCHASE
AGREEMENT TO THE CONTRARY, THE UNDERSIGNED HEREBY 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, the
undersigned 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 undersigned 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 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 this Letter of Transmittal, the undersigned represents that
either (i) the undersigned 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 undersigned understands that a tender of Units to the Purchaser will
constitute a binding agreement between the undersigned and the Purchaser upon
the terms and subject to the conditions of the Offer. The undersigned recognizes
that under certain circumstances set forth in the Offer, the Purchaser may not
be required to accept for payment any of the Units tendered hereby. In such
event, the undersigned understands that any Letter of Transmittal for Units not
accepted for payment may be destroyed by the Purchaser (or its agent). EXCEPT AS
STATED IN THE OFFER, THIS TENDER IS IRREVOCABLE, PROVIDED 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 UNDERSIGNED 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 UNDERSIGNED HAS MADE HIS OR HER OWN DECISION TO TENDER UNITS.

    The undersigned hereby represents and warrants for the benefit of the
Partnership and the Purchaser that the undersigned owns the Units tendered
hereby 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 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 are in compliance with all applicable laws and
regulations.

    Our records indicate that the undersigned owns the number of Units set forth
in the box above entitled "Description of Units Tendered" under the column
entitled "Total Number of Units Owned." If you would like to tender only a
portion of your Units, please so indicate in the space provided in the box above
entitled "Description of Units Tendered."

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

    The undersigned further represents and warrants that, to the extent a
certificate evidencing the Units tendered hereby (the "original certificate") is
not delivered by the undersigned together with this Letter of Transmittal, (i)
the undersigned represents and warrants to the Purchaser that the undersigned
has not sold, transferred, conveyed, assigned, pledged, deposited or otherwise
disposed of any portion of the Units, (ii) the undersigned has caused a diligent
search of its records to be taken and has been unable to locate the original
certificate, (iii) if the undersigned shall find or recover the original
certificate evidencing the Units, the undersigned will immediately and without
consideration surrender it to the Purchaser; and (iv) the undersigned 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.

                              (See Instruction 4)

         By signing the Letter of Transmittal in the Signature Box, the
unitholder certifies as true under penalty of perjury, the representations in
Boxes A, B and C below. Please refer to the attached Instructions for completing
this Letter of Transmittal and Boxes A, B and C below.


================================================================================
                                      BOX A
                               SUBSTITUTE FORM W-9
                           (SEE INSTRUCTION 4 - BOX A)
- --------------------------------------------------------------------------------

    The unitholder hereby certifies the following to the Purchaser under
penalties of perjury:

         (i) The Taxpayer Identification No. ("TIN") printed (or corrected) on
the front of this Letter of Transmittal is the correct TIN of the unitholder,
unless the Units are held in an Individual Retirement Account ("IRA"); or if
this box is checked, the unitholder has applied for a TIN. 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); and

         (ii) Unless this box is checked, the unitholder is not subject to
backup withholding either because the unitholder: (a) is exempt from backup
withholding; (b) has not been notified by the IRS that the unitholder is subject
to backup withholding as a result of a 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.

    Note: Place an "X" in the box in (ii) above, only if you are unable to
certify that the unitholder is not subject to backup withholding.

                           (SEE INSTRUCTION 4 - BOX B)
- --------------------------------------------------------------------------------

    Under Section 1445(e)(5) of the Internal Revenue Code and Treas. Reg.
1.1445-11T(d), a transferee must withhold tax equal to 10% of the amount
realized with respect to certain transfers of an interest in a partnership if
50% or more of the value of its gross assets consists of U.S. real property
interests and 90% or more of the value of its gross assets consists of U.S. real
property interests plus cash equivalents, and the holder of the partnership
interest is a foreign person. To inform the Purchaser that no withholding is
required with respect to the unitholder's Units in the Partnership, the person
signing this Letter of Transmittal hereby certifies the following under
penalties of perjury:

         (i) Unless this box is checked, 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 the Letter of Transmittal;

         (iii) The unitholder's home address (for individuals), or office
address (for non-individuals), is correctly printed (or corrected) on the front
of this Letter of Transmittal.

         The person signing this Letter of Transmittal 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.

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

    By checking this box , the person signing this Letter of Transmittal hereby
certifies under penalties of perjury that the unitholder is an "exempt foreign
person" for purposes of the Backup Withholding rules under the U.S. Federal
income tax laws, because the unitholder has the following characteristics:

         (i)   Is a nonresident alien individual or a foreign corporation,
               partnership, estate or trust;

         (ii)  If an individual, has not been and plans not to be present in the
               U.S. for a total of 183 days or more during the calendar year;
               and

         (iii) Neither engages, nor plans to engage, in a U.S. trade or business
               that has effectively connected gains from transactions with a
               broker or barter exchange.

    4.      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 Letter of Transmittal or if consideration is to
            be sent to someone other than such signer or to an address other
            than that set forth on the Letter of Transmittal in the box entitled
            "Description of Units Tendered," the appropriate boxes on the Letter
            of Transmittal should be completed.

    5.      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 A, Box
            B and, if applicable, Box C. By signing the Signature Box, the
            unitholder(s) certifies that the TIN as printed (or corrected) on
            this Letter of Transmittal in the box entitled "Description of Units
            Tendered" and the representations made in Box A, Box B and, if
            applicable, Box C, 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 A and Box B.

       BOX A - SUBSTITUTE FORM W-9.

       Part (i), Taxpayer Identification Number -- Tendering unitholders must
       certify to the Purchaser that the TIN as printed (or corrected) on this
       Letter of Transmittal 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. DO NOT CHECK THE BOX IN BOX A, PART (ii), UNLESS YOU HAVE BEEN
       NOTIFIED BY THE IRS THAT YOU ARE SUBJECT TO BACKUP WITHHOLDING.

       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

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

       BOX B - 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 obtained from the IRS. PART (I)
       SHOULD BE CHECKED ONLY IF THE TENDERING UNITHOLDER IS NOT A U.S. PERSON,
       AS DESCRIBED THEREIN.

       BOX C - 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 certify,
       under penalties of perjury, the statement in Box C of this Letter of
       Transmittal, attesting to that Foreign Person's status by checking the
       box preceding such statement. UNLESS THE BOX IS CHECKED, SUCH UNITHOLDER
       WILL BE SUBJECT TO 31% WITHHOLDING OF TAX.

    6.      VALIDITY OF LETTER OF TRANSMITTAL. All questions as to the validity,
            form, eligibility (including time of receipt) and acceptance of a
            Letter of Transmittal 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 this Letter of
            Transmittal) 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. This Letter of Transmittal 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 a Letter of Transmittal and will incur no liability for
            failure to give such notification.

    7.      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.

    8.      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.

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.

certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.

                                 August 19, 1999

Dear Unitholder:

         We are offering to acquire up to 12,498.55 units in your partnership,
Angeles Partners XI. 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 $110 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, and you will receive distributions, if any,
         payable in respect of your units.

         We are offering to acquire up to 12,498.55 outstanding units in your
partnership. Our offer is subject to a minimum of 35% of the units being
tendered. If more units are tendered than we are offering to acquire, we will
prorate the purchase so that the same approximate percentage of units tendered
by each partner will be purchased. YOU WILL NOT BE REQUIRED TO PAY US 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. We
will pay for accepted units promptly after 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. These documents describe the material risks and opportunities
associated with the offer, including certain tax considerations. Please review
these documents carefully. 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 your financial position, your need or desire for
liquidity, other financial opportunities available to you, and your tax position
and the tax consequences to you of selling your units.

         If you desire to tender any of your units in response to our offer, you
should complete and sign the enclosed letter of transmittal in accordance with
the enclosed instructions and mail or deliver the signed letter of transmittal
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 September 16, 1999, unless extended.
If you have questions or require further information, please call the
Information Agent, toll free, at (888) 349-2005.

                                       Very truly yours,
