Ladies and Gentlemen:

     The undersigned hereto hereby acknowledges that he or she has received (i)
the Purchaser's Offer to Purchase dated the date set forth above (the "Offer
Date"), relating to the offer by AIMCO Properties, L.P. (the "Purchaser") to
purchase Limited Partnership Interests (the "Units") in 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").

     THE GENERAL PARTNER OF YOUR PARTNERSHIP DOES NOT MAKE ANY RECOMMENDATION
REGARDING WHETHER YOU SHOULD ACCEPT THE OFFER. YOU ARE ENCOURAGED TO CAREFULLY
REVIEW THE OFFER TO PURCHASE AND ANY OTHER INFORMATION AVAILABLE TO YOU AND TO
SEEK ADVICE FROM YOUR INDEPENDENT LAWYER, TAX ADVISOR AND/OR FINANCIAL ADVISOR
WITH RESPECT TO YOUR PARTICULAR CIRCUMSTANCES BEFORE DECIDING WHETHER OR NOT TO
ACCEPT THE OFFER.

     Upon the terms and subject to the conditions set forth in the Offer to
Purchase, and this Letter of Transmittal, the undersigned hereto 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 indicated on the Offer
and any supplement thereto, 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.

     By executing this Letter of Transmittal, the undersigned hereby
acknowledges that the general partner does not make any recommendation regarding
whether the undersigned should accept the Offer, and the undersigned hereto
represents and warrants to the Purchaser that the undersigned has received the
Offer.

     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
hereto 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, 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 the Offer, in respect of the
Units tendered by the undersigned and accepted for payment and thereby purchased
by the Purchaser; (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 and
certificate of limited partnership of the Partnership (the "Partnership
Agreement"), or any agreement pursuant to which the Units were sold (the
"Purchase Agreement"), whether as contractual obligations, damages, insurance
proceeds, condemnation awards or otherwise; (iii) all of the 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
whether on behalf of the Partnership, individually or on behalf of a putative
class (including without limitation any claims against limited partners of the
Partnership, the general partner(s) and/or any affiliates thereof) under,
arising out of or related to the Partnership Agreement, the Purchase Agreement,
the undersigned's status as a limited partner, the terms or conditions of the
Offer, the management of the Partnership, monies loaned or advanced, services
rendered to the Partnership or its partners, or any other claims arising out of
or related to the undersigned's ownership of Units in the Partnership.

     The undersigned hereto, on behalf of himself or herself, his or her heirs,
estate, executor, administrator, successors and assigns, and the Partnership,
fully, finally and forever releases, relinquishes and discharges the Purchaser
and its predecessors, successors and assigns and its present and former parents,
subsidiaries, affiliates, investors, insurers, reinsurers, officers, directors,
employees, agents, administrators, auditors, attorneys, accountants, information
and solicitation agents, investment bankers,

                                        3


and other representatives, including but not limited to Apartment Investment and
Management Company and the general partner of the Partnership (collectively, the
"Releasees"), from any and all claims and causes of action, whether brought
individually, on behalf of a class, or derivatively, demands, rights, or
liabilities, including, but not limited to, claims for negligence, gross
negligence, professional negligence, breach of duty of care or loyalty, or
breach of duty of candor, fraud, breach of fiduciary duty, mismanagement,
corporate waste, malpractice, misrepresentation, whether intentional or
negligent, misstatements and omissions to disclose, breach of contract,
violations of any state or federal statutes, rules or regulations, whether known
claims or unknown claims that have been asserted or that could have been
asserted against the Releasees, through and including the date of execution of
the letter of transmittal, including, but not limited to, those claims that
arise out of or relate to (a) those matters and claims set forth in the Nuanes
and Heller class and derivative litigation described in the Offer to Purchase,
(b) the ownership of one or more Units in the Partnership, including but not
limited to, any and all claims related to the management of the Partnership or
the properties owned by the Partnership (whether currently or previously), the
payment of management fees or other monies to the general partner of the
Partnership and its affiliates, prior acquisitions or tender offers and the
prior settlement, (c) the purchase, acquisition, holding, sale, tender or voting
of one or more Units in the Partnership, or (d) any of the facts, circumstances,
allegations, claims, causes of action, representations, statements, reports,
disclosures, transactions, events, occurrences, acts, omissions or failures to
act, of whatever kind or character whatsoever, irrespective of the state of mind
of the actor performing or omitting to perform the same, that have been or could
have been alleged in any pleadings, amended pleading, argument, complaint,
amended complaint, brief, motion, report or filing in the Nuanes and Heller
class and derivative litigation (collectively, the "Released Claims"); provided,
however, that the Released Claims are not intended to include (i) any unrelated
claims that are unique to a unitholder or settlement class member (e.g., a
settlement class member slips and falls on property owned by one of the
defendants in the Nuanes and Heller class and derivative litigation, loses or
did not receive a distribution check distributed to other limited partners in
such partnership, or is an employee of one of the defendants and has an
employee-related claim), (ii) any claim based on violations of federal or state
securities laws in connection with the Offer, and (iii) any right to your pro
rata share of the settlement fund in the Nuanes and Heller settlement, assuming
that you are otherwise eligible, and the settlement and judgment thereto become
final.

     The undersigned hereto expressly waives and relinquishes, to the fullest
extent permitted by law and consistent with the releases contained herein, the
provisions, rights and benefits of Section 1542 of the Civil Code of California
("Section 1542"), which provides:

     A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
     KNOW OR SUSPECT TO EXIST IN ITS FAVOR AT THE TIME OF EXECUTING THE RELEASE,
     WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
     DEBTOR.

     The undersigned hereto waives any and all provisions, rights and benefits
conferred by any law of any state or territory of the United States, or
principle of common law, that is similar, comparable or equivalent to Section
1542. The undersigned acknowledges and agrees that it may hereafter discover
facts in addition to or different from those which it now knows or believes to
be true with respect to the subject matter of the Released Claims, but the
undersigned shall be deemed to have fully, finally and forever settled and
released any and all Released Claims, known or unknown, suspected or
unsuspected, contingent or non-contingent, that now exist or heretofore have
existed upon any theory of law or equity now existing, including, but not
limited to, conduct that is negligent, intentional, with or without malice, or a
breach of any duty, law or rule, without regard to the subsequent discovery of
the existence of such different or additional facts.

     The undersigned hereto agrees that the releases contained herein are
intended to include the Released Claims, which the undersigned may have and
which the undersigned does not know or suspect to exist in its favor against the
Releasees and that the releases contained herein extinguish those claims. The
undersigned hereto represents and warrants to the Releasees that the undersigned
has been advised by its

                                        4


attorney of the effect and import of the provisions of Section 1542, and that
the undersigned has not assigned or otherwise transferred or subrogated any
interest in the Released Claims.

     Subject to and effective upon acceptance for payment of any Unit tendered
hereby in accordance with the terms of the Offer, the signatory agrees not to
bring any action, claim, suit or proceeding against the Purchaser and its
affiliates who were defendants in the Nuanes and Heller class and derivative
litigation concerning any of the matters that are the subject of the Stipulation
of Settlement approved by the Court in connection with the settlement of such
class and derivative litigation, other than for violations of federal or state
securities law.

     The undersigned hereto irrevocably appoints the Purchaser and its designees
as his or her proxy, each with full power of substitution, to the fullest extent
of the undersigned's rights with respect to the Units tendered by him or her and
accepted for payment by the Purchaser. Such proxy shall be considered coupled
with an interest in the tendered Units. Such appointment will be effective upon
receipt of this Letter of Transmittal. Upon receipt of this Letter of
Transmittal, all prior proxies and consents given by the undersigned hereto with
respect to the Units will, without further action, be revoked, and no subsequent
proxies or consents may be given (and if given will not be effective). The
Purchaser and its designees are, as to those Units, empowered to exercise all
voting and other rights as a limited partner as the Purchaser, in its
discretion, may deem proper at any meeting of limited partners, by written
consent or otherwise. By executing this Letter of Transmittal, the undersigned
agrees to execute all such documents and take such other actions as shall be
reasonably required to enable the Units tendered to be voted in accordance with
the Purchaser's directions. The proxy granted by the undersigned hereto to the
Purchaser will remain effective and be irrevocable for a period of ten years
following the Expiration Date of the Offer.

     The undersigned hereto 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 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 or declared 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
purchase of the Units by the Purchaser and will remain effective and be
irrevocable for a period of ten years following the Expiration Date of the
Offer. Upon purchase of the Units pursuant to the Offer, all prior powers of
attorney given by the undersigned hereto with respect to such Units will be
revoked and no subsequent powers of attorney may be given (and if given will not
be deemed effective).

     In addition to and without limiting the generality of the foregoing, the
undersigned hereto hereby irrevocably (i) requests and authorizes (subject to
and effective upon acceptance for payment of any Unit tendered hereby) the
Partnership and its general partner 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 terms of the Partnership Agreement; (ii) empowers the
Purchaser and its agent to execute and deliver to the 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

                                        5


Units, to be effective on the books and records of the Partnership as of the
effective date set forth in the Offer.

     NOTWITHSTANDING ANY PROVISION IN THE PARTNERSHIP AGREEMENT OR ANY PURCHASE
AGREEMENT TO THE CONTRARY, THE UNDERSIGNED HERETO HEREBY DIRECTS THE 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 hereto 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 hereto 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 or all of the Units
tendered hereby. In such event, the undersigned understands that any Letter of
Transmittal for Units not accepted for payment may be returned to the
undersigned or destroyed by the Purchaser (or its agent). THIS TENDER IS
IRREVOCABLE, EXCEPT THAT UNITS TENDERED PURSUANT TO THE OFFER MAY BE WITHDRAWN
AT ANY TIME PRIOR TO THE EXPIRATION DATE, OR UNLESS ALREADY ACCEPTED FOR
PAYMENT, ANY TIME AFTER 60 DAYS FROM THE OFFER DATE.

     THE UNDERSIGNED HAS BEEN ADVISED THAT THE PURCHASER IS AN AFFILIATE OF THE
GENERAL PARTNER OF THE PARTNERSHIP. THE UNDERSIGNED HERETO HAS MADE HIS OR HER
OWN DECISION TO TENDER UNITS.

     The undersigned hereto 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.

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

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

                                        6


consideration surrender it to the Purchaser; and (iv) the undersigned shall at
all times indemnify, defend, and save harmless the Purchaser and the
Partnership, its successors, and its assigns from and against any and all
claims, actions, and suits whether groundless or otherwise, and from and against
any and all liabilities, losses, damages, judgments, costs, charges, counsel
fees, and other expenses of every nature and character by reason of honoring or
refusing to honor the original certificate when presented by or on behalf of a
holder in due course of a holder appearing to or believed by the partnership to
be such, or by issuance or delivery of a replacement certificate, or the making
of any payment, delivery, or credit in respect of the original certificate
without surrender thereof, or in respect of the replacement certificate.

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 Units is a foreign
person. To inform AIMCO Properties, L.P. that no withholding is required with
respect to the unitholder's Units in the Partnership, the undersigned hereby
certifies the following under penalties of perjury:

    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 is not a disregarded entity as defined in Treas.
    Reg. Section 1.1445-2(b)(2)(iii);

        (iii) The unitholder's U.S. social security number (for individuals) or
    employer identification number (for non individuals) is correct as furnished

IRS by AIMCO Properties, L.P. and that any false statements contained herein
could be punished by fine, imprisonment, or both.

    Under penalties of perjury I declare that I have examined this certification

                      FOR COMPLETING LETTER OF TRANSMITTAL

     1.  REQUIREMENTS OF TENDER.  To be effective, a duly completed and signed
         Letter of Transmittal (or facsimile thereof) and any other required
         documents must be received by the Information Agent at one of its
         addresses (or its facsimile number) set forth herein on or before the
         date and time of the Expiration Date, unless extended. To ensure
         receipt of the Letter of Transmittal and any other required documents,
         it is suggested that you use overnight courier delivery or, if the
         Letter of Transmittal and any other required documents are to be
         delivered by United States mail, that you use certified or registered
         mail, return receipt requested.

         Our records indicate that you own the number of Units set forth in the
         box above entitled "Description of Units Tendered" under the column
         entitled "Name(s), Address(es), Number of Units Owned and Tax
         Identification Number of Registered Holder(s)." 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."

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

         THE METHOD OF DELIVERY OF THE LETTER OF TRANSMITTAL AND ALL OTHER
         REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING
         UNITHOLDER AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED
         BY THE INFORMATION AGENT. IN ALL CASES, SUFFICIENT TIME SHOULD BE
         ALLOWED TO ASSURE TIMELY DELIVERY.

         signature(s) must correspond exactly with the names printed (or
         corrected) on the front of the Letter of Transmittal. NO SIGNATURE
         GUARANTEE ON THE LETTER OF TRANSMITTAL IS REQUIRED IF THE LETTER OF
         TRANSMITTAL IS SIGNED BY THE UNITHOLDER (OR BENEFICIAL OWNER IN THE
         CASE OF AN IRA). If any tendered Units are registered in the names of
         two or more joint owners, all such owners must sign this Letter of
         Transmittal.

         IRAS/ELIGIBLE INSTITUTIONS.  For Units held in an IRA account, the
         beneficial owner should sign in the Signature Box and no signature
         guarantee is required. Similarly, no signature guarantee is required if
         Units are tendered for the account of a member firm of a registered
         national security exchange, a member firm 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").

         executors, administrators, guardians, attorneys-in-fact, officers of a
         corporation, authorized partners of a partnership or other persons
         acting in a fiduciary or representative capacity must sign at the "X"
         in the Signature Box and have their signatures guaranteed by an
         Eligible Institution by completing the signature guarantee set forth in
         the Signature Box of the Letter of Transmittal. If the Letter of
         Transmittal is signed by trustees, administrators, guardians,
         attorneys-in-fact, officers of a corporation, authorized partners of a
         partnership or others acting in a fiduciary or representative capacity,
         such persons should, in addition to having their signatures guaranteed,
         indicate their title in the Signature Box and must submit proper
         evidence satisfactory to the Purchaser of their authority to so act
         (see Instruction 3 below).

     3.  DOCUMENTATION REQUIREMENTS.  In addition to the information required to

     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 and Box
         B. 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 provided in Box A 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 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.

                                        11


         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.
         Single member limited liability company -- should reflect the TIN of
         the owner of the Units for federal income tax purposes.

         NON-U.S. PERSONS.  In order for a unitholder that is not a U.S. Person
         ("Non-U.S. Person") to qualify as exempt, such unitholder must submit a
         completed Form W-8BEN "Certificate of Foreign Status," Form W-8ECI
         "Certificate of Foreign Person's Claim for Exemption from Withholding
         on Income Effectively Connected with the Conduct of a U.S. Trade or
         Business," or Form W-8IMY "Certificate of Foreign Intermediary, Foreign
         Flow Through Entity or Certain U.S. Branches for United States Tax
         Withholding" signed under penalties of perjury attesting to such exempt
         status. Such forms may be obtained from the IRS at www.irs.gov.

         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 amount realized 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.

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

     7.  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.

     8.  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.

     9.  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.

            GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                         NUMBER ON SUBSTITUTE FORM W-9

WHAT NAME AND NUMBER TO GIVE THE REQUESTER

  NAME

     If you are an individual, you must generally enter the name shown on your
Social Security card. However, if you have changed your last name, for instance,
due to marriage, without informing the Social Security Administration of the
name change, enter your first name, the last name shown on your Social Security
card, and your new last name. If the account is in joint names, list first and
then circle the name of the person or entity whose number you enter in Part I of
the form.

     Sole Proprietor -- You must enter your individual name as shown on your
Social Security card. You may enter your business, trade or "doing business as"
name on the Business Name line.

     Limited Liability Company (LLC) -- If you are a single-member LLC
(including a foreign LLC with a domestic owner) that is disregarded as an entity
separate from its owner under Treasury regulations sec. 301.7701-3, enter the
owner's name. Enter the LLC's name on the Business Name line. A disregarded
domestic entity that has a foreign owner must use the appropriate Form W-8.

     Other Entities -- Enter the business name as shown on required federal
income tax documents. This name should match the name shown on the charter or
other legal document creating the entity. You may enter any business, trade or
"doing business as" name on the Business Name line.

  TAXPAYER IDENTIFICATION NUMBER (TIN)

     You must enter your taxpayer identification number in the appropriate box.
If you are a resident alien and you do not have and are not eligible to get a
Social Security number, your taxpayer identification number is your IRS
individual taxpayer identification number (ITIN). Enter it in the Social
Security number box. If you do not have an individual taxpayer identification
number, see OBTAINING A NUMBER below. If you are a sole proprietor and you have
an employer identification number, you may enter either your Social Security
number or employer identification number. However, using your employer
identification number may result in unnecessary notices to the requester, and
the IRS prefers that you use your Social Security number. If you are an LLC that
is disregarded as an entity separate from its owner under Treasury regulations
sec. 301.7701-3, and are owned by an individual, enter the owner's Social
Security number. If the owner of a disregarded LLC is a corporation,
partnership, etc., enter the owner's employer identification number. See the
chart below for further clarification of name and TIN combinations.

                                        13


Social Security numbers have nine digits separated by two hyphens: i.e.,
000-00-0000. Employer identification numbers have nine digits separated by only
one hyphen: i.e., 00-0000000. The table below will help determine the number to
give the payer.

For interest and dividends, the following payees are generally exempt from

  Code of 1986, as amended (the "Code"), an individual retirement account (IRA),

- A person registered under the Investment Advisors Act of 1940 who regularly

Exempt payees described above should file substitute Form W-9 to avoid possible
erroneous backup withholding. FILE THIS FORM WITH THE PAYER. FURNISH YOUR
TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND
RETURN IT TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS, OR PATRONAGE
DIVIDENDS, ALSO SIGN AND DATE THE FORM. IF YOU ARE A NONRESIDENT ALIEN OR A
FOREIGN ENTITY NOT SUBJECT TO BACKUP WITHHOLDING, FILE WITH PAYER A COMPLETED
INTERNAL REVENUE FORM W-8 (CERTIFICATE OF FOREIGN STATUS).

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

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

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

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

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