Under penalties of perjury, the Signatory certifies that: (1) the number shown
on this form is the unitholder's correct Taxpayer Identification No. ("TIN") or
the unitholder has applied for a TIN; and (2) the unitholder is not subject to
backup withholding either because the unitholder: (a) is exempt for backup
withholding; (b) has not been notified by the Internal Revenue Service ("IRS")
that the unitholder is subject to back-up withholding as a result of failure to
report all interest or dividends; or (c) has been notified by the IRS that such
unitholder is no longer subject to backup withholding.
Certification Instructions - You must cross out item (2) in the paragraph above
if you have been notified by the IRS that you are subject to back-up withholding
because of underreporting interest or dividends on your tax return. However, if
after being notified by the IRS that you were subject to back-up withholding you
received another notification from the IRS that you are no longer subject to
back-up withholding, do not cross out item (2).
Please check this box if the unitholder has applied for a TIN, a TIN has not
been issued to the unitholder, and either (a) the unitholder has mailed or
delivered an application to receive a TIN to the appropriate IRS Center or
Social Security Administration Office, or (b) the unitholder intends to mail or
deliver an application in the near future (it being understood that if the
unitholder does not provide a TIN to the Purchaser, 31% of all reportable
payments made to the unitholder will be withheld).

Section 1445(e)(5) of the Internal Revenue Code and Treas. Reg.1.1445-11T(d)
provide that a transferee of the U.S. real property interest must withhold tax
equal to 10% of the amount realized if the transferor is a foreign person. To
inform the Purchaser that withholding of tax is not required upon this
disposition of a U.S. real property interest, the undersigned hereby certifies
the following under penalties of perjury: (i) the unitholder, if an individual,
is a U.S. citizen or a resident alien for purposes of U.S. income taxation, and
if other than an individual, is not a foreign corporation, foreign partnership,
foreign estate or foreign trust (as those terms are defined in the Internal
Revenue Code and Income Tax Regulations); (ii) the unitholder's U.S. social
security number (for individuals) or employer identification number (for
non-individuals) is correct as furnished in the blank provided for that purpose
on the front of this Acknowledgment and Agreement; and (iii) the unitholder's
home address (for individuals), or office address (for non-individuals), is
correctly printed (or corrected) on the front of this Acknowledgment and
Agreement. The person signing this Acknowledgment and Agreement understands that
this certification may be disclosed to the IRS by the Purchaser and that any
false statements contained herein could be punished by fine, imprisonment, or
both.
[ ] Please check this box if the withholding of tax is required because the
unitholder does not satisfy all of the above conditions.
================================================================================
ACKNOWLEDGMENT AND AGREEMENT. The signatory hereto (the "Signatory") hereby
acknowledges that he or she has received (i) the Purchaser's Offer to Purchase,
dated the Offer Date (as supplemented or amended from time to time, the "Offer
to Purchase") relating to the offer by AIMCO Properties, L.P. (the "Purchaser")
to purchase units of limited partnership interest in the Partnership, (ii) the
Letter of Transmittal attached as Annex II thereto (the "Letter of
Transmittal"), (iii) this Acknowledgment and Agreement, and (iv) the
Instructions hereto in the Letter of Transmittal, as each may be supplemented or
amended from time to time, and whose terms and conditions are incorporated by
reference herein (collectively, the "Offer"). Capitalized terms used herein but
not otherwise defined herein shall have the meanings ascribed thereto in the
Offer to Purchase. The Signatory hereby understands and agrees that the Letter
of Transmittal is hereby incorporated by reference herein and is hereby made a
part hereof.
The Signatory hereby makes the representations, warranties, and covenants,
and agrees to the terms and conditions, in each case set forth in the Letter of
Transmittal, and hereby tenders to the Purchaser the units of limited
partnership interest set forth in the box entitled "Description of Units
Tendered" herein, including all interests represented by such units
(collectively, the "Units"), as described in the Offer to Purchase and certifies
under penalties of perjury that the statements in Box 6 and Box 7 herein are
true.
The Signatory hereby irrevocably constitutes and appoints the Purchaser and
any designees of the Purchaser as the true and lawful agent and attorney-in-fact
of the Signatory with respect to such Units, with full power of substitution
(such power of attorney being deemed to be an irrevocable power coupled with an
interest), to vote or act in such manner as any such attorney and proxy or
substitute shall, in its sole discretion, deem proper with respect to such Units
on any matter submitted for the consent or approval of holders of such Units, to
do all such acts and things necessary or expedient to deliver such Units and
transfer ownership of such Units on the partnership books maintained by the
managing general partner of the Partnership, together with all accompanying
evidence of transfer and authenticity to, or upon the order of, the Purchaser,
to sign any and all documents necessary to authorize the transfer of the Units
to the Purchaser including, without limitation, the "Transferor's (Seller's)
Application for Transfer" created by the National Association of Securities
Dealers, Inc., if required, and upon receipt by the Information Agent (as the
Signatory's agent) of consideration pursuant to the terms of the Offer, to
become a holder of units, to receive any and all distributions made by the
Partnership to which the Purchaser is entitled pursuant to the terms of the
Offer (regardless of the record date for any such distribution), and to receive
all benefits and otherwise exercise all rights of beneficial ownership of such
Units, all in accordance with the terms of the Offer. This appointment shall be
effective upon the purchase of the Units by the Purchaser as provided in the
Offer and shall be irrevocable for a period of ten years following the
termination of the Offer. Upon the purchase of Units pursuant to the Offer, all
prior proxies and consents given by the Signatory with respect to such Units
will be revoked and no subsequent proxies or consents may be given (and if given
will not be deemed effective).
In addition to and without limiting the generality of the foregoing, the
Signatory hereby irrevocably (i) requests and authorizes (subject to and
effective upon acceptance for consideration of any Unit tendered hereby) the
Partnership and its general partners to take any and all actions as may be
required to effect the transfer of the Units to the Purchaser (or its designee)
and to admit the Purchaser as a holder of units in the Partnership under the
terms of the certificate and agreement of partnership of the Partnership; (ii)
empowers the Purchaser and its agent to execute and deliver to the managing
general partner a change of address form instructing the managing general
partner to send any and all future distributions to the address specified in the
form, and to endorse any check payable to or upon the order of such unitholder
representing a distribution to which the Purchaser is entitled pursuant to the
terms of the Offer, in each case in the name and on behalf of the tendering
unitholder; (iii) agrees not to exercise any rights pertaining to the Units
without the prior consent of the Purchaser; and (iv) requests and consents to
the transfer of the Units, to be effective on the books and records of the
Partnership as of the effective date set forth in the Offer.
In addition, the Signatory irrevocably constitutes and appoints the
Purchaser and any designees of the Purchaser as the true and lawful agent and
attorney-in-fact of the Signatory with respect to such Units, with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), to withdraw any or all of such Units that have been
previously tendered in response to any tender or exchange offer provided that
the consideration being offered by the Purchaser is equal to or higher than the
consideration being offered in the other tender or exchange offer. This
appointment is effective immediately and shall continue to be effective unless
and until such Units are withdrawn from the offer by the Signatory prior to the
expiration date (as defined in the Offer).
All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the Signatory, and any obligations of the Signatory shall
be binding upon the heirs, personal representatives, trustees in bankruptcy,
legal representatives, and successors and assigns of the Signatory.
