                           OFFER TO PURCHASE FOR CASH

                             AIMCO Properties, L.P.
                  is offering to purchase up to 12,862.33 units
                       of limited partnership interest in

                               Angeles Partners XI
                            for $77 per unit in CASH


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

We will only accept a maximum of 32.46% of the outstanding units in response to
our offer. If more units are tendered to us, we will generally accept units on a
pro rata basis according to the number of units tendered by each person.

Our offer and your withdrawal rights will expire at 5:00 p.m., New York City
time, on June 29, 1999, unless we extend the deadline.

YOU WILL NOT PAY ANY FEES OR COMMISSIONS IF YOU TENDER YOUR UNITS.

Our offer is not subject to any minimum number of units being 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 $77 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 estimated the net liquidation
                  value of your units to be $207.88 per unit.

         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.

         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.

         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.

                                  INTRODUCTION

                  We are offering to purchase up to 12,862.33 units,
representing approximately 32.46% of the outstanding units of limited
partnership interest in your partnership, for the purchase price of $77 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 commissions or 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
not conditioned on any minimum number of units being tendered. However, certain
other conditions do 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
June 29, 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 July 11,
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 March 31, 1999, AIMCO owned or managed 373,409
apartment units in 2,071 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.

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.



                                        1

<PAGE>   4


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 a 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 a property and the tax consequences to you and your
partners on a sale of property. We cannot predict when any property will be sold
or otherwise disposed of.

HOLDING UNITS MAY RESULT IN GREATER FUTURE VALUE

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

CONFLICTS OF INTEREST WITH RESPECT TO THE OFFER; NO GENERAL PARTNER
RECOMMENDATION

                  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 





                                       2
<PAGE>   5

determined our offer price without negotiation with any other party, including
any general or limited partner. Because of our affiliation with the general
partner of your partnership, your general partner makes no recommendation as to
whether you should tender 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 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
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 are no longer subject to the
"passive loss" rules with respect to your partnership. Because the income tax
consequences of tendering units will not be the same for everyone, you should
consult your own tax advisor with specific reference to your own tax situation.

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.

POSSIBLE INCREASE IN CONTROL OF YOUR PARTNERSHIP BY US

                  Because the general partner of your partnership is our
subsidiary, we control the management of your partnership. In addition, if we
acquire more units, we will increase our ability to influence voting decisions
with respect to your partnership and may control such voting decisions.
Furthermore, in the event that we acquire a substantial number of units pursuant
to our offer, removal of a general partner without our consent may become more
difficult or impossible. We also own a majority of the company that manages the
residential property owned by your partnership. In the event that we acquire a
substantial number of units pursuant to our offer, removal of any property
manager without our consent may become more difficult or even impossible.



                                       3
<PAGE>   6

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.

                                    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 12,862.33 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 June 29,
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.

                  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 12,862.33 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 12,862.33 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 12,862.33 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 



                                       4
<PAGE>   7

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 NOT CONDITIONED UPON ANY MINIMUM AMOUNT OF 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 right of
limited partners to withdraw units until the expiration date or on or after July
11, 1999, retain the units that have been tendered during the period or periods
for which the offer is extended, or (iv) amend the offer. For administrative
purposes, the transfer of units will be effective March 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 May 13, 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 12,862.33 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.

                  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.



                                       5
<PAGE>   8

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 and accepted for payment by you. 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 




                                       6
<PAGE>   9

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 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 the 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 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 July 11, 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."

                  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 the payment
for, any unit, (ii) to terminate our offer and not accept for payment any units
not theretofore accepted for payment or paid for, (iii) upon the occurrence of
any of the conditions specified in "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.



                                       8
<PAGE>   11

                  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 Federal income tax consequences of the offer that may be relevant to (i)
unitholders who tender some or all of their units for cash pursuant to our
offer, and (ii) unitholders who do not tender any of their units pursuant to our
offer. This discussion is based on the Internal Revenue Code of 1986, as amended
(the "Internal Revenue Code"), Treasury Regulations, rulings issued by the
Internal Revenue Service (the "IRS"), and judicial decisions, all as of the date
of this offer to purchase. All of the foregoing are subject to change or
alternative construction with possible retroactive effect, and any such change
or alternative construction could affect the continuing accuracy of this
summary. Such summary is based on the assumption that your partnership will be
operated in accordance with its organizational documents including its
certificate of limited partnership and agreement of limited partnership. This
summary is for general information only and does not purport to discuss all
aspects of Federal income taxation which may be important to a particular person
in light of its investment or tax circumstances, or to certain types of
investors subject to special tax rules (including financial institutions,
broker-dealers, insurance companies, and, except to the extent discussed below,
tax-exempt organizations and foreign investors, as determined for United States
Federal income tax purposes), nor (except as otherwise expressly indicated) does
it describe any aspect of state, local, foreign or other tax laws. This summary
assumes that the units constitute capital assets in the hands of the unitholders
(generally, property held for investment). No advance ruling has been or will be
sought from the IRS regarding any matter discussed in this offer to purchase.
Further, no opinion of tax counsel has been obtained with regard to the offer.

                  THE 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 FEDERAL INCOME TAX LAW FOR WHICH NO
CLEAR PRECEDENT OR AUTHORITY MAY BE AVAILABLE. ACCORDINGLY, YOU SHOULD CONSULT
YOUR TAX ADVISOR REGARDING THE 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 pursuant to the offer 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 tax liability resulting from a sale of a unit of limited
partnership of your partnership could exceed the cash received upon such sale.



                                       9
<PAGE>   12

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

                  CHARACTER OF GAIN OR LOSS RECOGNIZED PURSUANT TO THE OFFER.
Except as described below, the gain or loss recognized by you on a sale of a
unit of limited partnership of your partnership pursuant to the offer generally
will be treated as a long-term capital gain or loss if you held the unit for
more than one year. Long-term capital gains recognized by individuals and
certain other noncorporate taxpayers generally will be subject to a maximum
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 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%) to the extent of previously claimed depreciation
deductions that would not be treated as "unrealized receivables."

                  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 shelter 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 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 




                                       10
<PAGE>   13

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 no longer be suspended and will 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. Accordingly, you
should 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 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
Federal income tax withholding of 31% with respect to the payment of the offer
consideration, you may have to provide us with your correct taxpayer
identification number. See the instructions to the letter of transmittal.

                  Gain realized by a foreign person on the sale of a unit
pursuant to the offer will be subject to Federal income tax under the Foreign
Investment in Real Property Tax Act. 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 Federal income tax
liability and, if in excess thereof, a refund could be obtained from the
Internal Revenue Service by filing a U.S. income tax return. See the
instructions to the letter of transmittal.

                  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 Federal income tax purposes. It is possible that our acquisition of units
pursuant to the offer could result in such a termination of your partnership.
Notwithstanding the fact that the agreement of limited partnership of your
partnership may prohibit a transfer of ownership of an interest that would cause
a tax termination, the assignment to us of rights to distributions with respect
to units may cause a termination of your partnership for Federal income tax
purposes. If your partnership is deemed to terminate for tax purposes, the
following Federal income tax events will be deemed to occur: the terminated
partnership will be deemed to have contributed all of its assets (subject to its
liabilities) to a new partnership in exchange for an interest in the new
partnership and, immediately thereafter, the old partnership will be deemed to
have distributed interests in the new partnership to the remaining limited
partners in proportion to their respective interests in the old partnership in
liquidation of the old partnership.

                  A remaining limited partner will not 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 will change (and
possibly shorten) a remaining partner's holding period with respect to its
retained units in your partnership for 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.





                                       11
<PAGE>   14

                  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 22.83% 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
27.17% 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 any agreement of
limited partnership, the operations of any partnership, the business and
property owned by any partnership, the management compensation payable to any
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 security holders 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 8.        INFORMATION CONCERNING US AND CERTAIN OF OUR AFFILIATES.

                  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, a Maryland corporation
("AIMCO"). AIMCO is a real estate investment trust that owns and manages
multifamily apartment properties throughout the United States. Based on
apartment unit data compiled by the National Multi-Housing Council, we believe

multifamily apartment properties in the United States, with a total portfolio of
373,409 apartment units in 2,071 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 of March 31, 1999,
AIMCO:

                  o        owned or controlled 63,069 units in 240 apartment
                           properties;

                           apartment properties; and

                  o        managed 141,523 units in 940 apartment properties for
                           third party owners and affiliates.

                  Our general partner is AIMCO-GP, Inc., which is a wholly owned

                  Neither we nor, to the best of our knowledge, any of the
persons listed on Annex I attached hereto, (i) beneficially own or have a right
to acquire any units, (ii) have effected any transaction in the units in the
past three years, 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 (except for
previous tender offers we may have conducted for units).

SECTION 9.        BACKGROUND AND REASONS FOR THE OFFER.

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

                  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 our subsidiaries, AIMCO currently owns, in the aggregate,
approximately 27.17% 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.

                  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 (excluding 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 



                                       14

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 private transactions, and any
liquidation 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.

                  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 




                                       15
<PAGE>   18

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
budgets 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 and beneficial ownership reports on Schedules 13D, 14D-1 and
14D-9. Our determination of the offer price was based on our review and analysis
of the foregoing information and the analyses concerning the partnership
summarized below.

                  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.

         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
         11% to derive an estimated gross property value of $35,733,000.

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
         $3,091,587. 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 appraisals of your partnership's properties. 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, 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.

         PRICES ON SECONDARY MARKET

         Secondary market sales activity for the units, including privately
negotiated sales, has been limited and sporadic. Set forth in the table below
are the high and low sales prices of units for the quarterly periods from
January 1, 1996 to March 31, 1999, as reported by The Partnership Spectrum,
which is an independent, third-party source. The gross sales prices reported by
The Partnership Spectrum do not necessarily reflect the net sales proceeds
received by sellers of units, which typically are reduced by commissions and
other secondary market transaction costs to amounts less than the reported
prices; thus, we do not know whether the information complied by The Partnership
Spectrum is accurate and complete. 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. Accordingly, you
should not rely upon this information as being completely accurate.

     which typically are reduced by commissions and other secondary market
     transaction costs to amounts less than the reported prices. We do not know
     whether the information compiled by The Partnership Spectrum is accurate or
     complete.

         We believe that, although secondary market sales information probably
is not a reliable measure of value because of the limited and inefficient nature
of the market for units, this information may be relevant to a limited partner's
decision as to whether to tender his or her units pursuant to the offer. At
present, privately negotiated sales and sales through intermediaries are the
only means available to a limited partner to liquidate an investment in units
(other than the offer) because the units are not listed or traded on any
exchange or quoted, on NASDAQ, on the Electronic Bulletin Board, or on "pink
sheets."

         APPRAISALS

         Your partnership's properties were 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 reports, 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 $35,733,000.

         The total appraised value of the property is $32,600,000. However, the
appraisal does not reflect the mortgage encumbering the properties of
$31,268,000 (including interest), other assets and liabilities of the
partnership or any costs of sale of the properties. Using the appraisal amount
instead of the "Estimated gross valuation of partnership properties" in the
table in "Valuation of Units" would result in a higher amount per unit than our
offer. Previously, an affiliate of your general partner relied on such appraisal
amounts to calculate an estimated net liquidation value of $207.88 per unit.

         We believe that, based on the condition of the property, the appraisals
substantially overstate their value. The appraisals did not take into account
the deferred maintenance costs of the partnership's property. Therefore, we
believe that the appraisals are less meaningful than our analysis described
above.

         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




                                       20
<PAGE>   23

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.

         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.

         Your general partner is our subsidiary. Therefore, the general partner
of your partnership has substantial conflicts of interest with regard to the
offer and makes no recommendation as to whether you should tender or refrain
from tendering your units. You must make your own decision whether or not to
participate in the offer, based upon a number of factors, including your
financial position, need or desire for liquidity, other financial opportunities
and tax position.

         Your general partner has not retained an unaffiliated representative to
act on behalf of the limited partners in negotiating the terms of the offer
since each individual limited partner can make his or her own decision as to
whether or not to tender. Unlike a merger or other form of partnership
reorganization, the preferences of other limited partners in your partnership
cannot bind you. If an unaffiliated representative had been obtained, it is
possible that such representative could have negotiated a higher price for your
units than we are offering.



                                       21
<PAGE>   24

         The terms of our offer have been established by us and are not the
result of arms-length negotiations. In determining the terms of the offer, we
considered the following factors and information:

         1.       The opportunity for you to make an individual decision on
                  whether to tender your units in the offer and that the offer
                  allows each investor to continue to hold his or her units.

         2.       The estimated value of your partnership's property has been
                  determined based on a method believed to reflect the valuation
                  of such assets by buyers in the market.

         3.       An analysis of the possible alternatives including liquidation
                  and continuation without the option of the offer. See "The
                  Offer -- Section 9. Background and Reasons for the Offer --
                  Alternatives Considered."

         4.       An evaluation of the financial condition and results of
                  operations of your partnership and AIMCO Properties, L.P. and
                  their anticipated level of operating results. The offer is not
                  expected to have an effect on your partnership's financial
                  condition or results of operations. The net income of your
                  partnership has increased from a net loss of $973,000 for the
                  year ended December 31, 1997 to $19,000 for the year ended
                  December 31, 1998. These factors are reflected in our
                  valuation of your partnership.

         5.       The method of determining the offer price which is
                  substantially the financial equivalent to your interest in
                  your partnership. See "The Offer -- Section 9. Background and
                  Reasons for the Offer -- Valuation of Units."

         6.       The fact that the units are illiquid and the offer provides
                  holders of units with liquidity. However, we did review
                  whether trading information was available.

         7.       The estimated unit value of $77, based on a total estimated
                  value of your partnership's property of $35,733,000. Your
                  general partner (which is our subsidiary) has no present
                  intention to liquidate your partnership or to sell or
                  refinance your partnership's property. See "The Offer --
                  Section 9. Background and Reasons for the Offer -- Valuation
                  of Units" for a detailed explanation of the methods we used to
                  value your partnership.

         8.       The offer price in light of any previous tender offers and the
                  results of such offers since the results of the offer indicate
                  a price at which some limited partners sold their units. See
                  "The Offer -- Section 9. Background and Reasons for the Offer
                  -- Prior Tender Offers."

         9.       The fact that if your partnership was liquidated as opposed to
                  continuing, the general partner would not receive the
                  substantial management fees it currently receives. We do not
                  believe that liquidation of the partnership is in the best
                  interests of the unitholders. We are not proposing to change
                  the current management fee arrangement.

         In evaluating these factors, we did not quantify or otherwise attach
particular weight to any of them.

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




                                       22
<PAGE>   25

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 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. 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 





                                       23
<PAGE>   26

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. However, we expect that consistent with your general
partner's fiduciary obligations, the general partner will seek and review
opportunities (including opportunities identified by us) to engage in
transactions which could benefit your partnership, such as sales or refinancings
of assets or a combination of the partnership with one or more other entities,
with the objective of seeking to maximize returns to limited partners.

         We have been advised that the possible future transactions the general
partner expects to consider on behalf of your partnership include: (1) payment
of extraordinary distributions; (2) refinancing, reducing or increasing existing
indebtedness of the partnership; (3) sales of assets, individually or as part of
a complete liquidation; and (4) mergers or other consolidation transactions
involving the partnership. Any such merger or consolidation transaction could
involve other limited partnerships in which your general partner or its
affiliates serve as general partners, or a combination of the partnership with
one or more existing, publicly traded entities (including, possibly, affiliates
of AIMCO), in any of which limited partners might receive cash, common stock or
other securities or consideration. There is no assurance, however, as to when or
whether any of the transactions referred to above might occur. If any such
transaction is effected by the partnership and financial benefits accrue to the
limited partners of your partnership, we will participate in those benefits to
the extent of our ownership of units. The agreement of limited partnership
prohibits limited partners from voting on actions taken by the partnership,
unless otherwise specifically permitted therein. Limited partners may vote on a
liquidation, and if we are successful in acquiring a substantial number of units
pursuant to the offer, we will be able to control the outcome of any such vote.
Even if we acquire a lesser number of units pursuant to the offer, however,
because we currently own approximately 27.174% 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.



                                       24

         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
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.

         SELECTED FINANCIAL AND PROPERTY-RELATED DATA. The summary financial
information of Angeles Partners XI for the years ended December 1998 and 1997 is
based on audited financial statements. This




                                       25

information should be read in conjunction with such financial statements,
including notes thereto, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations of Your Partnership" in the Annual Report on

         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 for the five
years ended December 31, 1998.

         OPERATING BUDGETS 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>
<S>                                                     <C>       
          Total Revenues............................    $7,783,339
          Operating Expenses........................    (3,162,703)
          Replacement Reserves -- Net...............            --
          Debt Service..............................    (2,798,541)
          Capital Expenditures......................            --
                                                        ----------
                    Net Cash Flow...................    $1,822,095
                                                        ==========
</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 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 




                                       27
<PAGE>   30

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 1998 will be. For the year ended
December 31, 1999, 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 27.17% 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 three years, 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:

</TABLE>

           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
York, and Chicago, Illinois. Please call the SEC at 1-800-SEC-0330 for further
information on the public reference rooms. Your partnership's SEC filings are
also available to the public at the SEC's web site at http://www.sec.gov.

SECTION 14.       VOTING POWER.

           If we acquire a substantial number of additional units pursuant to
our offer, we may be in a position to influence or control voting decisions with
respect to the limited partners of your partnership. See "The Offer -- 
Section 7. Effects of the Offer."

                                       28
<PAGE>   31

SECTION 15.       SOURCE OF FUNDS.

           We expect that approximately $990,399 will be required to purchase up
to 12,862.33 of the outstanding limited partnership units (exclusive of fees and
expenses estimated to be $12,000). For more information regarding the fees and
expenses, see "The Offer -- Section 19."

           We will obtain all necessary funds from working capital or from our
$100 million revolving credit facility with Bank of America National Trust and
Savings Association ("Bank of America") and BankBoston, N.A. AIMCO Properties,
L.P. is the borrower under the credit facility, and all obligations thereunder
are guaranteed by AIMCO and certain of its subsidiaries. The annual interest
rate under the credit facility is based on either LIBOR or Bank of America's
reference rate, at our election, plus, an applicable margin. We elect which
interest rate will be applicable to particular borrowings under the credit
facility. The margin ranges between 2.25% and 2.75% in the case of LIBOR-based
loans and between 0.75% and 1.25% in the case of base rate loans, depending upon
a ratio of our consolidated unsecured indebtedness to the value of certain
unencumbered assets. The credit facility matures on September 30, 1999 unless
extended, at the discretion of the lenders. The credit facility provides for the
conversion of the revolving facility into a three year term loan. The
availability of funds to us under the credit facility is subject to certain
borrowing base restrictions and other customary restrictions, including
compliance with financial and other covenants thereunder. The financial
covenants require us to maintain a ratio of debt to gross asset value of no more
than 0.55 to 1.0, an interest coverage ratio of 2.25 to 1.0 and a fixed charge
coverage ratio of at least 1.7 to 1.0 from January 1, 1999 through June 30,
1999, and 1.8 to 1.0 thereafter. In addition, the credit facility limits us from
distributing more than 80% of our Funds From Operations (as defined) to holders
of our units, imposes minimum net worth requirements and provides other
financial covenants related to certain unencumbered assets.

SECTION 16.       DISSENTERS' RIGHTS.

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

SECTION 17.       CONDITIONS OF THE OFFER.

           Notwithstanding any other provisions of our offer, we will not be
required to accept for payment and pay for any units tendered pursuant to our
offer, may postpone the purchase of, and payment for, units tendered, and may
terminate or amend our offer if at any time on or after the date of this offer
to purchase and at or before the expiration of our offer (including any
extension thereof), any of the following shall occur:

are or may be materially adverse to your partnership or the value of the units

indices in the United States such that there shall have occurred at least a 7.5%
increase in LIBOR or at least a 7.5% decrease in the S&P 500 Index, the Morgan
Stanley REIT Index, or the price of the 10-year Treasury Bond or the 30-year

change in the commercial mortgage financing markets, (iv) a declaration of a

material acceleration or worsening thereof; or

         (c) there shall have been threatened, instituted or pending any action,

serving as general partner of the partnership or to remove such entity as
general partner of your partnership, or seeks to impose any material limitation
on our ability or the ability of any affiliate of ours to conduct your
partnership's business or own such assets, (iv) seeks to impose material
limitations on our ability to acquire or hold or to exercise full rights of
ownership of the units including, but not limited to, the right to vote the
units purchased by us on all matters properly presented to the limited partners,
or (v) might result, in our reasonable judgment, in a diminution in the value of
your partnership or a limitation of the benefits expected to be derived by us as
a result of the transactions contemplated by our offer or the value of the units
to us; or

         (d) there shall be any action taken, or any statute, rule, regulation,
order or injunction shall be sought, proposed, enacted, promulgated, entered,
enforced or deemed applicable to our offer, your partnership, any general
partner of your partnership, us or any affiliate of ours or your partnership, or

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.



                                       31

         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."

Ladies and Gentlemen:

         The undersigned hereby acknowledges that he or she has received and
reviewed (i) the Purchaser's Offer to Purchase, dated May 13, 1999 (the "Offer
Date") relating to the offer by AIMCO Properties, L.P. (the "Purchaser") to
purchase Limited Partnership Interests (the "Units") in Angeles Partners XI, a
California limited partnership (the "Partnership") and (ii) this Letter of
Transmittal and the Instructions hereto, as each may be supplemented or amended
from time to time (collectively, the "Offer").

         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
Tendered," including all interests in any limited partnership represented by
such units (collectively, the "Units"), at the price of $77 per Unit, less the
amount of distributions, if any, made by the Partnership from the Offer Date
until the Expiration Date (the "Offer Price"), net to the 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
Partnership, and the undersigned's interest in all profits, losses and
distributions of any kind to which the undersigned shall at any time be entitled
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
"Purchase Agreement"), whether as contractual obligations, damages, insurance
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
Purchase Agreement or the undersigned's ownership of the Units, including,
without limitation, all voting rights, rights of first offer, first refusal or
similar rights, and rights to be substituted as a limited partner of the
Partnership; and (iv) all present and future claims, if any, of the undersigned
against the Partnership, the other partners of the Partnership, or the general
partner and its affiliates, including the Purchaser, under or arising out of the
Partnership Agreement, the Purchase Agreement, the undersigned's status as a
limited partner, or the terms or conditions of the Offer, for monies loaned or
advanced, for services rendered, for the management of the Partnership or
otherwise.

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

         In addition to and without limiting the generality of the foregoing,
the undersigned hereby irrevocably (i) requests and authorizes (subject to and
effective upon acceptance for payment of any Unit tendered hereby) the
Partnership and its general partners to take any and all actions as may be
required to effect the transfer of the undersigned's Units to the Purchaser (or
its designee) and to admit the Purchaser as a substitute limited partner in the
Partnership under the 


                                       3
<PAGE>   4

terms of the Partnership Agreement; (ii) empowers the Purchaser and its agent to
execute and deliver to each general partner a change of address form instructing
the general partner to send any and all future distributions to the address
specified in the form, and to endorse any check payable to or upon the order of
such unitholder representing a distribution to which the Purchaser is entitled
pursuant to the terms of the offer, in each case, in the name and on behalf of
the tendering unitholder; (iii) agrees not to exercise any rights pertaining to
the Units without the prior consent of the Purchaser; and (iv) requests and
consents to the transfer of the Units, to be effective on the books and records
of the Partnership as of March 1, 1999.

         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 JULY 11, 1999.

         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

                               TAX CERTIFICATIONS
                              (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.

                                      BOX B
                                FIRPTA AFFIDAVIT
                           (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.

                                      BOX C
                               SUBSTITUTE FORM W-8
                           (See Instruction 4 - Box C)

         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.

         it is suggested that you use overnight courier delivery or, if the
         Letter of Transmittal and any other required documents are to be

         mail, return receipt requested.

    WHEN TENDERING, YOU MUST SEND ALL PAGES OF THE LETTER OF TRANSMITTAL,
    INCLUDING TAX CERTIFICATIONS (BOXES A, B, AND C).

    THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED

    Letter of Transmittal, to tender Units, unitholders must sign at the "X" in
    the Signature Box of the Letter of Transmittal. The signature(s) must
    correspond exactly with the names printed (or corrected) on the front of the
    Letter of Transmittal. If the Letter of Transmittal is signed by the
    unitholder (or beneficial owner in the case of an IRA), no signature
    guarantee on the Letter of Transmittal is required. If any tendered Units
    are registered in the names of two or more joint owners, all such owners

    Transmittal. If the Letter of Transmittal is signed by trustees,

    authorized partners of a partnership or others acting in a fiduciary or
    representative capacity, such persons should, in addition to having their

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
    first.

    Trust accounts - should reflect the TIN assigned to the trust.

    IRA custodial accounts - should reflect the TIN of the custodian (not
    necessary to provide).

    Custodial accounts for the benefit of minors - should reflect the TIN of the
    minor. Corporations, partnership or other business entities - should reflect
    the TIN assigned to that entity.


                                       9
<PAGE>   10

    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.

9.       MINIMUM TENDERS. A unitholder may tender any or all of his, her or its
         Units.

10.      CONDITIONAL TENDERS. No alternative, conditional or contingent tenders
         will be accepted.

does not furnish a correct taxpayer identification number to a payer. Certain
penalties may also apply.

    PENALTIES

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

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

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

Dear Unitholder:

    We are offering to acquire up to 12,862.33 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 $77 cash, in which
    case you may recognize a gain or loss for federal income tax purposes.

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

    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. We are offering to acquire any and all outstanding
units in your partnership. Our offer is not subject to any minimum number of
units being tendered. YOU WILL NOT BE REQUIRED TO PAY ANY COMMISSIONS OR FEES IN
CONNECTION WITH ANY DISPOSITION OF YOUR UNITS PURSUANT TO OUR OFFER. Our offer
price will be reduced for any distributions subsequently made by your
partnership prior to the expiration of our offer.

    There are advantages and disadvantages to you of accepting or declining our
offer. The terms of the offer are more fully described in the enclosed
materials. 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, which is
owned by us, has substantial conflicts of interest with respect to the offer.
Accordingly, the general partner of your partnership makes no recommendation to
you as to whether you should tender or refrain from tendering your units in the
offer.

    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 June 29, 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,
