                    2.1      GUARANTEED OBLIGATIONS.

                             (a)              Subject to the express limitations
         set forth in subsection 2.2, Guarantor irrevocably, absolutely and
         unconditionally guarantees to Fannie Mae, as primary obligor and not
         merely as surety, the full, due and punctual payment of all
         obligations of each of the Borrowers to Fannie Mae when the same shall
         become due (whether at stated maturity, by required prepayment,
         declaration, acceleration, demand or otherwise, including amounts that
         would become due but for the operation of the automatic stay under
         Section 362(a) of the United States Bankruptcy Code (the "BANKRUPTCY
         CODE"), 11 U.S.C. Section  362(a)), now or hereafter made, incurred or
         created, whether absolute or contingent, liquidated or unliquidated
         and however arising under or in connection with the respective
         Transaction Documents to which such Borrower is a party (collectively,
         the "BORROWER OBLIGATIONS"), including (i) those obligations arising
         under successive transactions under such Transaction Documents which
         shall either continue the respective Borrower Obligations or from time
         to time renew them after they have been satisfied and (ii) interest
         which, but for the filing of a petition in bankruptcy with respect to
         the respective Borrower, would have accrued on such Borrower
         Obligations, whether or not a claim is allowed against such Borrower
         for such interest in the related bankruptcy proceeding. This Guaranty
         is an unconditional guaranty of payment and not of collection, and is
         in no way conditioned upon any attempt by Fannie Mae to collect from
         Borrowers or any of them. This Guaranty is a continuing guaranty which
         shall remain in full force and effect during and until the expiration
         of the Guaranty Period, and Guarantor shall not be released from any
         obligations to Fannie Mae under this Guaranty prior to the expiration
         of the





                                       10
   11
         Guaranty Period. Guarantor's obligations under this Section are
         referred to in this Guaranty as the "GUARANTEED OBLIGATIONS".

                             (b)              In addition to the Ambassador
         Documents, reference also is made to the Ambassador Pool-3 MRA between
         Fannie Mae and WLP. Guarantor acknowledges that, as of the date
         hereof, (i) an "Event of Default" under the Ambassador Pool-1 MRA or
         the Ambassador Pool-2 MRA also is an "Event of Default" under the
         Ambassador Pool-3 MRA, and vice versa (i. e., such documents are
         cross-defaulted), and (ii) the property owned by WLP also is
         collateral for the obligations under the Ambassador Documents, and the
         properties owned by the Ambassador Pool-1 Borrower and the Ambassador
         Pool-2 Borrower also are collateral for the obligations under the
         Ambassador Pool-3 MRA (i. e., the Ambassador Documents and the
         Ambassador Pool-3 MRA are cross-collateralized). Accordingly, although
         the property owned by WLP is not considered a "Property" for purposes
         of determining Excess Cash Flow under this Guaranty, and the
         obligations of WLP under the Ambassador Pool-3 MRA are not included
         within the definition of Borrower Obligations, an "Event of Default"
         under the Ambassador Pool-3 MRA will constitute an Event of Default"
         under the Ambassador Documents that will (x) be a Triggering Event
         under this Guaranty, and (y) entitle Fannie Mae to use Grantor Excess
         Cash Flow in the Master Lockbox and proceeds from a draw on the Letter
         of Credit to cure such Event of Default.

         2.2     LIMITATION ON AMOUNT GUARANTEED.

                             (a)              Notwithstanding any other 
         provision in this Guaranty to the contrary, but subject to subsection
         2.2(b) hereof, the liability of Guarantor to pay and perform the
         Borrower Obligations shall be limited to the amount (the "Maximum
         Guaranteed Amount") determined at any time and from time to time as the
         sum of (i) the cumulative Excess Cash Flow from the Pools from and
         after the occurrence and during the continuance of a Triggering Event
         plus (ii) an amount equal to the face amount of the Letter of Credit at
         such time. As collateral and security for the Maximum Guaranteed
         Amount, Guarantor shall (x) cause the Letter of Credit to be issued in
         favor of Fannie Mae pursuant to the Pledge and LOC Agreement and (y)
         pursuant to Pledge and LOC Agreement, pledge to and for the benefit of
         Fannie Mae amounts held in the Master Lockbox, proceeds from a draw on
         the Letter of Credit in accordance with Section 2.4 of the Pledge and
         LOC Agreement, Guarantor's right to receive Grantor Excess Cash Flow
         from entities in which Guarantor is a partner or member, and proceeds
         of the foregoing.





                                       11
   12
                             (b)              Notwithstanding the first sentence
         of subsection 2.2(a), Guarantor's obligations under this Guaranty
         shall not be limited to the Maximum Guaranteed Amount, but instead
         shall be in the full amount of the Guaranteed Obligations, from and
         after the occurrence of any of the following events: (i) Guarantor's
         failure to deposit (or cause to be deposited) into the Master Lockbox
         all Grantor Excess Cash Flow, as required pursuant to the Master
         Lockbox Agreement (including, without limitation, as a result of any
         depository bank disbursing Grantor Excess Cash Flow to Guarantor from
         and after the date on which Fannie Mae instructs such depository bank
         to cease transferring Grantor Excess Cash Flow to Guarantor as a
         result of a Triggering Event, rather than depositing such Grantor
         Excess Cash Flow into the Master Lockbox); (ii) a challenge by
         Guarantor or any of its Affiliates regarding the validity,
         enforceability or priority of the security interests granted to Fannie
         Mae pursuant to (or in connection with) the Pledge and LOC Agreement
         or the Master Lockbox Agreement, or any other action by Guarantor or
         any of its Affiliates that impairs the validity, enforceability or
         priority of such security interests (including a challenge to
         Guarantor's right to receive Grantor Excess Cash Flow or to pledge and
         deliver the Grantor Excess Cash Flow to Fannie Mae pursuant to the
         Master Lockbox Agreement); (iii) a determination that the
         representations and warranties set forth in Section 8(h) hereof were
         untrue as of the date hereof, or a breach of the covenants set forth
         in Section 23(d) hereof after the date hereof; (iv) from and after the
         occurrence and during the continuance of a Triggering Event,
         Guarantor's failure to pay or apply to Debt Service and Operating
         Expenses amounts disbursed to Guarantor (or to Borrowers or Affiliates
         of Guarantor or Borrowers) from the Master Lockbox for the payment of
         Debt Service or Operating Expenses; or (v) a challenge by Guarantor
         regarding Fannie Mae's right to draw on the Letter of Credit or use
         the proceeds therefrom in accordance with the Pledge and LOC
         Agreement. If any of the foregoing events occur, and Guarantor
         thereafter cures such matter, and Guarantor also cures any other Event
         of Default that then may exist under the Transaction Documents,
         Guarantor's obligations under this Guaranty from and after such cure
         shall once again be limited to the Maximum Guaranteed Amount as
         provided in subsection 2.2(a).

                             (c)              Anything contained in this 
         Guaranty to the contrary notwithstanding, Fannie Mae shall look solely
         to Guarantor and the assets of Guarantor (including, without
         limitation, the Letter of Credit and the collateral described in the
         Pledge and LOC Agreement and the Master Lockbox Agreement) for the
         payment of any amount or the performance of any obligation under this
         Guaranty, and Fannie Mae shall not look to the partners of Guarantor,
         or seek recourse against the partners of Guarantor, for the payment of
         any such amount or the performance of any such obligation.





                                       12
   13
                             (d)              Anything contained in this 
         Guaranty to the contrary notwithstanding, if any Fraudulent Transfer
         Law (as hereinafter defined) is determined by a court of competent
         jurisdiction to be applicable to the obligations of Guarantor under
         this Guaranty, such obligations of Guarantor hereunder shall be limited
         to a maximum aggregate amount equal to the largest amount that would
         not render its obligations hereunder subject to avoidance as a
         fraudulent transfer or conveyance under Section 548 of Title 11 of the
         United States Code or any applicable provisions of comparable state law
         (collectively, the "FRAUDULENT TRANSFER LAWS"), in each case after
         giving effect to all other liabilities of Guarantor, contingent or
         otherwise, that are relevant under the Fraudulent Transfer Laws
         (specifically excluding, however, any liabilities of Guarantor (i) in
         respect of intercompany indebtedness to the Borrowers or Affiliates of
         the Borrowers to the extent that such indebtedness would be discharged
         in an amount equal to the amount paid by Guarantor hereunder and (ii)
         under any guaranty of subordinated indebtedness which guaranty contains
         a limitation as to maximum amount similar to that set forth in this
         section 2.2(d), pursuant to which the liability of Guarantor hereunder
         is included in the liabilities taken into account in determining such
         maximum amount), and after giving effect as assets to the value (as
         determined under the applicable provisions of the Fraudulent Transfer
         Laws) of any rights to subrogation, reimbursement, indemnification or
         contribution of Guarantor pursuant to applicable law- or pursuant to
         the terms of any agreement.

                             (e)              No provision of this subsection 
         2.2 shall affect any other guaranty or similar agreement executed by
         any person or entity in connection with the Borrower Obligations,
         release or reduce all or any part of the Borrower Obligations or the
         debt evidenced by the Transaction Documents, impair the lien of any
         Transaction Documents, or impair the right of Fannie Mae to enforce the
         provisions of any Transaction Documents.

                 3.          FORM OF PAYMENT. Subject to the provisions of
subsection 2.2 hereof, in furtherance of the foregoing and not in limitation of
any other right which Fannie Mae may have at law or in equity against Guarantor
by virtue hereof, Guarantor agrees that upon the occurrence and during the
continuance of a Triggering Event, Guarantor will upon demand pay, or cause to
be paid, in cash, to Fannie Mae an amount equal to the sum of the unpaid
principal amount of all Borrower Obligations then due, accrued and unpaid
interest on such Borrower Obligations (including, without limitation, interest
which, but for the filing of a petition in bankruptcy with respect to such
Borrower, would have accrued on such Borrower Obligations, whether or not a
claim is allowed against such Borrower for such interest in the related
bankruptcy proceeding) and all other Guaranteed Obligations then owed to Fannie
Mae as aforesaid. All such payments shall be applied promptly from time to time
by Fannie Mae:





                                       13
   14
                          First, to the payment of the costs and expenses of
                 any collection or other realization under this Guaranty,
                 including reasonable compensation to Fannie Mae and its agents
                 and counsel, and all expenses, liabilities and advances made
                 or incurred by Fannie Mae in connection therewith; and


                          Second, to the payment of all other Guaranteed
                 Obligations in such order as Fannie Mae shall elect.

All payments under this Guaranty shall be made to Fannie Mae in immediately
available funds, without reduction by any recoupment, set-off, counterclaim or
cross-claim against Fannie Mae at such address as directed by Fannie Mae.
Notwithstanding the foregoing provisions of this Section 3, if Grantor Excess
Cash Flow is then on deposit in the Master Lockbox and otherwise available for
such purpose, Fannie Mae will, at the direction of Guarantor, allow the use of
such Grantor Excess Cash Flow to cure or satisfy the default or event giving
rise to the Triggering Event.

                          4.  GUARANTOR'S OBLIGATIONS ARE ABSOLUTE. Subject
to subsection 2.2 hereof, the obligations of Guarantor under this Guaranty
shall be absolute and unconditional, shall not be subject to any counterclaim,
set-off, recoupment, deduction or defense based upon any claim Guarantor may
have against Fannie Mae or any Borrower and shall remain in full force and
effect without regard to, and shall not be released, discharged or terminated
or in any other way affected by, any circumstance or condition (whether or not
Guarantor shall have any knowledge or notice thereof), including without
limitation:

                              (a)              any amendment or modification 
         of, or extension of time for payment of any of the principal of,
         interest on or other amounts payable under, any Transaction Documents
         (except that the liability of Guarantor hereunder shall be deemed to
         apply to such documents as so amended or modified or to the payment of
         all amounts so extended);

                              (b)              any exercise or non-exercise by
         Fannie Mae of any right, power or remedy taken or in respect of any
         Transaction Documents, or any waiver, consent, forbearance, indulgence
         or other action, inaction or omission by Fannie Mae under or in
         respect of any Transaction Documents;

                              (c)              any assignment, sale or other
         transfer of any Borrower's interest in all or any part of the real or
         personal property which at any time constitutes collateral for the
         payment of the Guaranteed Obligations including without limitation a





                                       14
   15
         conveyance of such property by a Borrower to Fannie Mae by deed in
         lieu of foreclosure;

                              (d)              any bankruptcy, insolvency,
         reorganization, adjustment, dissolution, liquidation or other like
         proceeding involving or affecting any Borrower or Fannie Mae or their
         respective properties or creditors, or any action taken with respect
         to any Transaction Documents by any trustee or receiver of Fannie Mae
         or any Borrower, or by any court, in any such proceeding;

                              (e)              any invalidity or 
         unenforceability, in whole or in part, of any term or provision of any
         Transaction Documents or any Borrower's incapacity or lack of authority
         to enter into its respective Transaction Documents;

                              (f)              any release, compromise, 
         settlement or discharge with respect to all or any portion of any
         Borrower's obligations under its respective Transaction Documents;

                              (g)              any acceptance of additional or
         substituted collateral for payment of the Guaranteed Obligations or
         any release or subordination of any collateral held at any time by
         Fannie Mae as security for the payment of the Guaranteed Obligations;

                              (h)              any resort to Guarantor for 
         payment of all or any portion of the Guaranteed Obligations, whether or
         not Fannie Mae shall have resorted to any collateral securing the
         Guaranteed Obligations or shall have proceeded against any Borrower or
         any other person or entity primarily or secondarily liable for the
         Borrower Obligations, it being intended that Fannie Mae may pursue its
         rights hereunder at any time or times; or

                              (i)              any waiver by Fannie Mae of any
         breach of any Transaction Documents by any Borrower.

                 No exercise, delay in exercise or non-exercise by Fannie Mae
of any right hereby given it, no dealing by Fannie Mae with any Borrower,
Guarantor or any other person or entity, no change, impairment or suspension of
any right or remedy of Fannie Mae, and no act or thing which, but for this
provision, could act as a release or exoneration of the liabilities of
Guarantor hereunder, shall in any way affect, decrease, diminish or impair any
of the obligations of Guarantor hereunder or give Guarantor or any other person
or entity any recourse or defense against Fannie Mae.





                                       15
   16
                 5.       WAIVER.  Guarantor unconditionally waives, for the
benefit of Fannie Mae, the following:

                          (a)              notice of acceptance of this
         Guaranty and notice of any of the matters referred to in Section 4
         hereof;

                          (b)              all notices to Guarantor which may
         be required by statute, rule of law or otherwise to preserve intact
         any rights which Fannie Mae may have against Guarantor under this
         Guaranty, including without limitation, any demand, proof or notice to
         Guarantor of non-payment of any of the principal of, interest on or
         other amounts payable under the Transaction Documents, and notice to
         Guarantor of any failure on the part of any Borrower to perform and
         comply with any covenant, agreement, term or condition of the
         applicable Transaction Documents;

                          (c)              any right to the enforcement,
         assertion or exercise of any right, power or remedy conferred in any
         Transaction Documents or otherwise;

                          (d)              any requirement that Fannie Mae act
         with diligence in enforcing its rights under any Transaction Documents
         or this Guaranty;

                          (e)              any right to require Fannie Mae to
         proceed against or exhaust its recourse against any Borrower, any
         guarantor under other guarantees in favor of Fannie Mae with respect
         to the Guaranteed Obligations, or any security or collateral held by
         Fannie Mae at any time for the payment of the Guaranteed Obligations
         or to pursue any other remedy in its power before being entitled to
         payment from Guarantor under this Guaranty or before proceeding
         against Guarantor (except as otherwise provided in Section 3 hereof);

                          (f)              any failure by Fannie Mae to file or
         enforce a claim against the estate (either in administration,
         bankruptcy or any other proceeding) of any Borrower or any other
         person or entity;

                          (g)              any defense based upon an election
         of remedies by Fannie Mae which destroys or otherwise impairs the
         subrogation rights of Guarantor or the right of Guarantor (after
         payment of the Guaran- teed Obligations) to proceed against any
         Borrower or any other person or entity for reimbursement, or both;

                          (h)              any defense based upon any taking,
         modification or release of any collateral for the Guaranteed
         Obligations, or any failure to perfect any security





                                       16
   17
         interest in, or the taking of, or failure to take any other action
         with respect to, any collateral securing payment of the Guaranteed
         Obligations;

                          (i)              any defense based upon the addition,
         substitution or release, in whole or in part, of any person or entity,
         including without limitation another guarantor, primarily or
         secondarily liable for or in respect of the Guaranteed Obligations;

                          (j)              any rights or defenses based upon an
         offset by Guarantor against any obligation now or hereafter owed to
         Guarantor by any Borrower or any other person or entity;

                          (k)              any defense of the statute of
         limitations in any action against Guarantor under this Guaranty;

                          (l)              any defense based upon any statute
         or rule of law which provides that the obligation of a surety must be
         neither larger in amount nor in other respects more burdensome than
         that of the principal;

                          (m)              any principles or provisions of law,
         statutory or otherwise, which are or might be in conflict with the
         terms of this Guaranty and any legal or equitable discharge of
         Guarantor's obligations hereunder;

                          (n)              all other notices to Guarantor which
         may or might be lawfully waived by Guarantor; it being the intention
         hereof that Guarantor shall remain liable as principal, to the extent
         set forth in this Guaranty, during and until the expiration of the
         Guaranty Period, notwithstanding any act, omission or thing which
         might otherwise operate as a legal or equitable discharge of Guarantor
         other than the payment in full of the Guaranteed Obligations.  No
         delay by Fannie Mae in exercising any rights and/or powers hereunder
         or in taking any action to enforce any of the Borrower Obligations
         shall operate as a waiver as to such rights or powers or in any manner
         prejudice any and all of Fannie Mae's rights and powers hereunder
         against Guarantor. It is the intention of Guarantor under this
         Guaranty that during and until the expiration of the Guaranty Period,
         the obligations of Guarantor hereunder shall not be discharged except
         by performance and then only to the extent of such performance.

                 6.       ELECTION OF REMEDIES. This Guaranty may be enforced 
from time to time, as often as occasion therefor may arise, and without any
requirement that Fannie Mae must first exercise any rights against any Borrower
or any other person or entity or exhaust any remedies available to it against
any Borrower under its Transaction Documents or against





                                       17
   18
any other person or entity or, except to the extent provided in Section 3
hereof, resort to any collateral at any time held by it for performance of the
Guaranteed Obligations or any other source or means of obtaining payment of any
of the Guaranteed Obligations.


                 7.       EXPENSES. Guarantor agrees to pay all costs and
out-of-pocket expenses, including court costs and expenses and the reasonable
fees and disbursements of legal counsel incurred by or on behalf of Fannie Mae
or the Servicers in connection with the preparation and negotiation of this
Guaranty and the other documents described in the Term Sheet (and the costs and
out-of-pocket expenses incurred in implementing the various steps described in
the Term Sheet), the enforcement of Guarantor's obligations under this Guaranty
and such other documents, or the protection of Fannie Mae's rights under this
Guaranty and such other documents. The covenant contained in this Section shall
survive the payment and satisfaction in full of the Guaranteed Obligations.

                 8.       REPRESENTATIONS AND WARRANTIES.  In order to induce
Fannie Mae to accept this Guaranty and consent to the Proposed Merger,
Guarantor represents and warrants to Fannie Mae as follows:


                          (a)     Guarantor is a duly formed limited
         partnership, validly existing and in good standing under the laws of
         the State of Delaware, and is qualified as a foreign limited
         partnership and, except where the failure to do so could not
         reasonably be expected to have a Material Adverse Effect, is in good
         standing under the laws of each jurisdiction in which such
         qualification and/or standing is necessary to the conduct of its
         business. Guarantor has the requisite power and authority to own its
         assets and to carry on its business as now conducted and to execute
         and deliver this Guaranty and to perform its obligations hereunder.

                          (b)     The execution, delivery and performance of
         this Guaranty and the transactions contemplated hereby have been duly
         authorized by all necessary action and proceedings by and on behalf of
         Guarantor, and no further consents, approvals or filings of any kind,
         including any consent or approval of or filing with any governmental
         authority, are required by or on behalf of Guarantor as a condition to
         the valid execution, delivery and performance by Guarantor of this
         Guaranty.

                          (c)     This Guaranty has been duly authorized,
         executed and delivered by Guarantor and constitutes the legal, valid
         and binding obligation of Guarantor, enforceable against Guarantor in
         accordance with its terms, except as enforceability may be limited by
         applicable bankruptcy, insolvency, reorganization, moratorium or





                                       18
   19
         similar laws or equitable principles affecting the enforcement of
         creditors' rights generally or by equitable principles or by the
         exercise of discretion by any court.

                          (d)     Guarantor is fully aware of the financial
         condition of each of the Borrowers and is executing and delivering
         this Guaranty based solely upon Guarantor's own independent
         investigation of all matters pertinent hereto and is not relying in
         any manner upon any representation or statement made by Fannie Mae or
         Servicers (except for any agreements or statements expressly made by
         Fannie Mae in this Guaranty or in any of the documents executed by
         Fannie Mae in accordance with the Term Sheet). Guarantor is in a
         position to obtain, and Guarantor hereby assumes full responsibility
         for obtaining, any additional information concerning Borrowers'
         financial condition and any other matters pertinent hereto as
         Guarantor may desire and Guarantor is not relying upon or expecting
         Fannie Mae or Servicers to furnish to Guarantor any information now or
         hereafter in Fannie Mae's or Servicers' possession concerning the same
         or any other matter. By executing this Guaranty, Guarantor knowingly
         accepts the full range of risks encompassed within a contract of this
         type, which risks Guarantor acknowledges.

                          (e)     Neither the execution and delivery of this
         Guaranty, nor Guarantor's performance of its obligations hereunder:

                                  (i)      does or will conflict with or result
                 in a breach or violation of any law, rule or regulation
                 enacted or issued by any governmental authority or other
                 agency having jurisdiction over Guarantor, Borrowers or any of
                 the Properties, or any judgment or order applicable to
                 Guarantor, Borrowers or any of the Properties or to which
                 Guarantor, Borrowers or any of the Properties are subject,
                 except for such breaches or violations that, singly or in the
                 aggregate, have not had, and are not reasonably expected to
                 cause, a Material Adverse Effect; or

                                  (ii)     does or will conflict with or result
                 in a breach or violation of, or constitute a default under,
                 any of the terms, conditions or provisions of Guarantor's
                 organizational documents, or, except for any such breach or
                 violation that could not reasonably be expected to have a
                 Material Adverse Effect, any indenture, existing agreement or
                 other instrument to which Guarantor is-a party or to which
                 Guarantor, Borrowers or any of the Properties are subject.

                          (f)     Guarantor is not insolvent and will not be
         rendered insolvent by the execution, delivery and performance of this
         Guaranty, nor will Guarantor have





                                       19
   20
         incurred, have intended to incur, or believe that it has incurred,
         debts beyond its ability to pay such debts as they mature. Guarantor
         did not receive less than a reasonably equivalent value in exchange
         for incurrence of the Guaranteed Obligations.  There is no
         contemplated, pending or, to the best of Guarantor's knowledge,
         threatened bankruptcy, reorganization, receivership, insolvency or
         like proceeding, whether voluntary or involuntary, affecting
         Guarantor, any of the Borrowers or any of the Properties, and there
         has been no assertion or exercise of jurisdiction over Guarantor,
         Borrowers or any of the Properties by any court empowered to exercise
         bankruptcy powers.

                          (g)     Guarantor is the owner of (directly or
         through one or more subsidiaries) or has a financial interest in
         (directly or through one or more subsidiaries), each of the Borrowers,
         and Fannie Mae's agreement to the Proposed Merger is of substantial
         and material benefit to Guarantor.  Guarantor has reviewed and
         approved copies of the Transaction Documents and is fully informed of
         the remedies Fannie Mae may pursue upon the occurrence of an event of
         default under the Transaction Documents.

                          (h)     As of the date hereof, AIMCO REIT's right to
         receive Excess Cash Flow is derived solely from the following
         interests owned by AIMCO REIT:

                                  (i)      AIMCO REIT's indirect ownership of
                 the .96% general partnership interest in Guarantor (through

                 corporation), and AIMCO REIT's indirect ownership of a limited
                 partnership interest in Guarantor (through AIMCO REIT's
                 ownership of AIMCO LP, Inc., a Delaware corporation);

                                  (ii)     AIMCO REIT's indirect ownership of a
                 2% general partnership interest in Holdings (through AIMCO
                 Holdings QRS, Inc., a Delaware corporation ("QRS"));

                                  (iii)    with respect to the AIMCO Pool II
                 Borrower, AIMCO REIT's ownership of (A) AIMCO/OTC QRS, Inc., a
                 Delaware corporation ("OTC QRS"), which is the sole general
                 partner (holding a I % general partnership interest) of such
                 Borrower, (B) QRS, which is a 2% general partner in Holdings,
                 which is a general partner or managing member in AIMCO/OTC,

                 each of which is a limited partner in such Borrower, (C)
                 AIMCO/HIL, L.L.C., which is a general partner of HomeCorp

                                       20
   21
                                  (iv)     with respect to the AIMCO Pool III

                 interest) of such Borrower, (B) QRS, which is a 2 % general
                 partner in Holdings, which is a 1 % managing member in
                 AIMCO/HIL, L.L.C., which is a general partner in HomeCorp
                 Investments, Ltd., which is a limited partner in such
                 Borrower, (C) Holdings, which is a general partner of HomeCorp
                 which is a limited partner in such Borrower and (D) Guarantor,
                 which is a limited partner in such Borrower;

                                  (v)      with respect to the Ambassador
                 Pool-1 Borrower, AIMCO REIT's ownership of Ambassador VIII,
                 Inc., a Delaware corporation, which is the sole general
                 partner (holding a 1 % general partnership interest) of such
                 Borrower; and (vi) with respect to the Ambassador Pool-2
                 Borrower, AIMCO REIT's ownership of (x) Ambassador I, Inc., a
                 Delaware corporation, which is the sole general partner
                 (holding a 1 % general partnership interest) of such Borrower,
                 and (y) AJ One Inc., a Delaware corporation, which is the sole
                 general partner (holding a 1 % general partnership interest)
                 in AJ One Limited Partnership, a Delaware limited partnership,
                 which entity is the sole general partner (holding a 49.6%
                 general partnership interest) in Jupiter-1, L.P., a Delaware
                 limited partnership, which entity is the sole limited partner
                 (holding a 99% limited partnership interest) in such Borrower

                 9.       FURTHER ASSURANCES. Guarantor agrees at any time and
from time to time upon reasonable request by Fannie Mae to take or cause to be
taken any action and to execute and deliver any additional documents which in
the opinion of Fannie Mae may be necessary in order to assure to Fannie Mae the
full benefits of this Guaranty.

                 10.      GUARANTOR'S RIGHTS OF SUBROGATION CONTRIBUTION, ETC.
During the Guaranty Period and for a period of thirteen (13) months after the
expiration thereof, Guarantor hereby waives any claim, right or remedy, direct
or indirect, that Guarantor now has or may hereafter have against any Borrower
or any of their respective assets in connection with this Guaranty or the
performance by Guarantor of its obligations hereunder, in each case whether
such claim, right or remedy arises in equity, under contract, by statute, under
common law or otherwise and including without limitation (a) any right of
subrogation, reimbursement or indemnification that Guarantor now has or may
hereafter have against any Borrower, (b) any right to enforce, or participate
in, any claim, right or remedy that Fannie Mae now has or may hereafter have
against any Borrower, and (c) any benefit of, and any right to participate in,
any collateral or security now or hereafter held by Fannie Mae. In addition,
until the





                                       21
   22
expiration of the Guaranty Period, Guarantor shall withhold exercise of any
right of contribution Guarantor may have against any other guarantor of the
Guaranteed Obligations. Guarantor further agrees that, to the extent the waiver
or agreement to withhold the exercise of its rights of subrogation,
reimbursement, indemnification and contribution as set forth herein is found by
a court of competent jurisdiction to be void or voidable for any reason, any
rights of subrogation, reimbursement or indemnification Guarantor may have
against any Borrower or against any collateral or security, and any rights of
contribution Guarantor may have against any such other guarantor, shall be
junior and subordinate to any rights Fannie Mae may have against such Borrower,
to all right, title and interest Fannie Mae may have in any such collateral or
security, and to any right Fannie Mae may have against such other guarantor. If
any amount shall be paid to Guarantor on account of any such subrogation,
reimbursement, indemnification or contribution rights at any time when all
Guaranteed Obligations shall not have been paid in full, such amount shall be
held in trust for Fannie Mae and shall forthwith be paid over to Fannie Mae to
be credited and applied against the Guaranteed Obligations, whether matured or
unmatured, in accordance with the terms hereof.

                 11.      SUBORDINATION OF OTHER OBLIGATIONS. Any indebtedness
of any Borrower now or hereafter held by Guarantor is hereby subordinated in
right of payment to the Guaranteed Obligations, and any such indebtedness of
any Borrower to Guarantor collected or received by Guarantor after an event of
default has occurred and is continuing under any of the Transaction Documents
shall be held in trust for Fannie Mae and shall forthwith be paid over to
Fannie Mae to be credited and applied against the Guaranteed Obligations but
without affecting, impairing or limiting in any manner the liability of
Guarantor under any other provision of this Guaranty.

                 12.      INSOLVENCY AND LIABILITY OF BORROWERS. So long as
this Guaranty is in effect, Guarantor agrees to file all claims against the
Borrowers in any bankruptcy or other proceeding in which the filing of claims
is required by law in connection with indebtedness owed by any Borrower to
Guarantor and to assign to Fannie Mae all rights of Guarantor thereunder up to
the amount of such indebtedness. In all such cases the person or entity
authorized to pay such claims shall pay to Fannie Mae the full amount thereof
to the full extent necessary to pay the Guaranteed Obligations and Guarantor
hereby assigns to Fannie Mae all of Guarantor'.s rights to all such payments to
which Guarantor would otherwise be entitled.  Notwithstanding the foregoing and
except to the extent that any sums owed by any Borrower to Fannie Mae under its
respective Transaction Documents shall have been fully satisfied thereby, the
liability of Guarantor hereunder shall in no way be affected by:

                          (a)     the release or discharge of any Borrower in
         any creditors', receivership, bankruptcy or other proceedings; or





                                       22
   23
                          (b)     the impairment, limitation or modification of
         the liability of any Borrower or the estate of any Borrower in
         bankruptcy resulting from the operation of any present or future
         provisions of the Bankruptcy Code or other statute or from the decision
         in any court.

                 13.      PREFERENCES FRAUDULENT CONVEYANCES ETC. If Fannie Mae
is required to refund, or voluntarily refunds, any payment received from any
Borrower because such payment is or may be avoided, invalidated, declared
fraudulent, set aside or determined to be void or voidable as a preference,
fraudulent conveyance, impermissible setoff or a diversion of trust funds under
the bankruptcy laws or for any similar reason, including without limitation any
judgment, order or decree of any court or administrative body having
jurisdiction over Fannie Mae or any of its property, or any statement or
compromise of any claim effected by Fannie Mae with any Borrower or any other
claimant (a "RESCINDED PAYMENT"), then Guarantor's liability to Fannie Mae
shall continue in full force and effect (subject to the limitations set forth
in subsection 2.2 hereof), or Guarantor's liability to Fannie Mae shall be
reinstated (subject to the limitations set forth in subsection 2.2 hereof), as
the case may be, with the same effect and to the same extent as if the
Rescinded Payment had not been received by Fannie Mae, notwithstanding the
cancellation or termination of any Transaction Documents.  In addition,
Guarantor shall pay, or reimburse Fannie Mae for, all expenses (including all
reasonable attorneys' fees, court costs and related disbursements) incurred by
Fannie Mae in the defense of any claim that a payment received by Fannie Mae in
respect of all or any part of the Guaranteed Obligations must be refunded.  The
provisions of this Section shall survive the termination of this Guaranty and
any satisfaction and discharge of the Borrowers by virtue of any payment, court
order or any federal or state law.

                 14.      WAIVER.  Neither this Guaranty nor any term hereof
may be changed, waived, discharged or terminated except by an instrument in
writing signed by Fannie Mae and Guarantor expressly referring to this Guaranty
and to the provisions so changed or limited. No such waiver shall extend to or
affect any obligation not expressly waived or impair any right consequent on
any obligation not expressly waived. No course of dealing or delay or omission
on the part of Fannie Mae in exercising any right under this Guaranty shall
operate as a waiver thereof otherwise be prejudicial thereto.

                 15.      NOTICES.  Any demand or notice required or permitted
to be given by Fannie Mae to Guarantor under this Guaranty shall be given by
certified or registered mail, return receipt requested, or by overnight courier
or by telecopy addressed to the appropriate notice address set forth below. Any
of the parties hereto may, by a notice to the other party specifically
captioned "Notice of Change of Address pursuant to Section 15 of the Payment
Guaranty", designate any further or different address to which subsequent
notices, certificates or other communications shall be sent without any
requirement of execution of any amendment

                 17.      WAIVER OF HOMESTEAD OR EXEMPTION RIGHTS. Guarantor
waives any and all homestead or exemption rights Guarantor may have under or by
virtue of any Constitution or laws of any State of the United States or the
District of Columbia with respect to the liability and obligation arising under
this Guaranty. Guarantor hereby transfers, conveys, and assigns to Fannie Mae a
sufficient amount of any homestead or exemption rights that may be allowed to
Guarantor, including any such homestead or exemption rights that may be set
apart in bankruptcy, to pay the obligations created by this Guaranty in full,
with all costs or collection. Guarantor hereby directs any party having
possession of such homestead of exemption rights, including a trustee in
bankruptcy to deliver to Fannie Mae a sufficient amount of property or money
set apart as exempt to pay Guarantor's obligations arising under this Guaranty.

                 18.      ASSIGNABILITY BY FANNIE MAE.  Fannie Mae may, without
notice to Guarantor, assign or transfer any of the Borrower Obligations owed to
Fannie Mae under the Transaction Documents, in whole or in part.  In such
event, each and every immediate and successive assignee, transferee or holder
of all or any part of the Borrower Obligations under the Transaction Documents
shall have the right to enforce this Guaranty, by legal action or otherwise, as
fully as if such assignee, transferee, or holder were by name specifically
given such right and power in this Guaranty. Fannie Mae shall have an
unimpaired right to enforce this Guaranty for its benefit as to so much of the
Borrower Obligations under the Transaction Documents as Fannie Mae has not
sold, assigned or transferred.

                 19.      GUARANTOR BOUND BY JUDGMENT AGAINST BORROWER.
Guarantor shall be conclusively bound in any jurisdiction by the judgment in
any action by Fannie Mae against Borrowers (or any of them) in connection with
the Transaction Documents (wherever instituted) as if Guarantor were a party to
such action even if not so joined as a party.

                 20.      RELEASE.  Promptly after the expiration of the
Guaranty Period, Fannie Mae (or, if any person or entity has succeeded to all
or any portion of Fannie Mae's interest hereunder, then such successor or
assign) shall execute and deliver to Guarantor a release under applicable law
releasing Fannie Mae's interest in this Guaranty and the Pledge and LOC
Agreement, and shall deliver to Guarantor any and all original copies of this
Guaranty then in the custody or possession of Fannie Mae (or such successor or
assign), all without recourse to or any warranty whatsoever by Fannie Mae (or
such successor or assign), and at the cost and expense of Guarantor.  Without
in any way limiting the obligations of Fannie Mae and any successor or assign
pursuant to the preceding sentence, Fannie Mae acknowledges that the
satisfaction, termination and/or reconveyance (as applicable) of all of the
Ambassador Documents encumbering the Properties described therein, and the
termination of the credit facility governed by the AIMCO Credit Facility
Transaction Documents, all in accordance with the respective terms of such
documents, and the passing of ninety-one (91) days after all of the foregoing
have





                                       27
   28
occurred, shall constitute conclusive evidence of the expiration of the
Guaranty Period (provided that no "Event of Default" then exists under any of
the Transaction Documents).

                 21.      GOVERNING LAW.  This Guaranty shall be construed and
enforced in accordance with, and the rights and remedies of the parties hereto
shall be governed by, the laws of the District of Columbia without regard to
conflicts of law, principles, except to the extent that Federal laws may
prevail.

                 22.      INVALID PROVISIONS.  Any provision of this Guaranty
that is prohibited, unenforceable or not authorized in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition,
unenforceability or nonauthorization without invalidating the remaining
provisions hereof or affecting the validity, enforceability or legality of such
provision in any other jurisdiction and the remaining portion of such provision
and all other remaining provisions will be construed to render them enforceable
to the fullest extent.  Guarantor and Fannie Mae shall endeavor in good-faith
negotiations to replace the invalid, illegal or unenforceable provisions with
valid provisions the economic effect of which comes as close as possible to
that of the invalid, illegal or unenforceable provisions.

                 23.      GUARANTOR'S COVENANTS.  Guarantor agrees and
covenants with Fannie Mae that, at all times that this Guaranty is in effect:

                          (a)     Guarantor shall at all times preserve and
         keep in full force and effect its existence and all rights and
         franchises material to its business.

                          (b)     Guarantor shall comply in all material
         respects with all applicable laws, rules, regulations and orders, such
         compliance to include, without limitation, paying when due all taxes,
         assessments and governmental charges imposed upon it or upon any of
         its properties or assets or in respect of any of its franchises,
         businesses, income or property before any penalty or interest accrues
         thereon.

                          (c)     Guarantor shall keep and maintain books of
         record and account with respect to its operations in accordance with
         generally accepted accounting principles and, to the extent permitted
         by law (including, without limitation, the Securities Exchange Act of
         1933, as amended), shall permit Fannie Mae and its officers, employees
         and authorized agents, to the extent Fannie Mae in good faith deems
         necessary for the proper administration of this Guaranty, to examine,
         copy and make excerpts from the books and records of Guarantor and its
         Affiliates (excluding any and all legally privileged materials) and to
         inspect the properties of Guarantor and the Borrowers, both real and
         personal, at such reasonable times during normal business hours as
         Fannie Mae may request. Fannie Mae covenants, for itself and its
         successors, assigns, agents and representa- tives, to (i)





                                       28
   29
         keep confidential all confidential, proprietary and/or non-public
         information, identified in writing as such by Guarantor and provided
         by Guarantor or its Affiliates to Fannie Mae or its successors,
         assigns, agents or representatives pursuant to, or in connection with,
         this Guaranty, and (ii) comply with all applicable securities laws in
         connection therewith.  Guarantor acknowledges that such information
         may be delivered to the successors, assigns, agents and
         representatives of Fannie Mae, provided that such successors, assigns,
         agents and representatives agree to be bound by the provisions of this
         Section 23(c).

                          (d)     Guarantor shall not agree to, permit or
         acquiesce in any amendment, modification, supplement or amendment and
         restatement (for purposes of this Section 23(d), an "AMENDMENT") of
         any of the following agreements:

                 receive proceeds or distributions with respect to, Holdings to
                 less than 98 %;

                                  (ii)     the partnership agreement for

                 OP to less than 99.9%;

                                  (iii)    (iii) the respective partnership

                 would have the effect of decreasing Guarantor's partnership
                 interest in, or right to receive proceeds or distributions
                 with respect to, such Borrowers to less than 98.42%, 90.7% and

                 distributions with respect to, such entities to more than 1 %;

                                  (iv)     the respective partnership
                 agreements for the AIMCO Pool IV Borrowers, if such Amendment

                                  (v)      the respective partnership or
                 limited liability company agreements for the AIMCO Credit
                 Facility Parties, if such Amendment would have the effect of
                 decreasing Guarantor's partnership interest in, or right to

                 Borrowers to less than 99 %; or

                                  (vii)    the partnership agreement with
                 respect to any other partner in any of the Borrowers, if such
                 Amendment would have the effect of decreasing Guarantor's
                 respective partnership interests in, or right to receive
                 proceeds or distributions with respect to, such partnerships
                 to less than the percentages or amounts as they exist as of
                 the date hereof.

indirectly owning any assets other than partnership interests in Guarantor,
except, in either case, the temporary ownership of other assets in connection
with an acquisition prior to contributing such assets to Guarantor.

shall establish the Master Lockbox and shall execute and deliver, or shall
cause its Affiliates identified in the Term Sheet to execute and deliver, all
of the agreements and documents described in the Term Sheet at the time(s)
specified therein.  Guarantor acknowledges that Fannie Mae's consent to the
Proposed Merger is conditioned on Guarantor's agreement to timely comply with
the foregoing covenant, and that Fannie Mae has materially relied on such
covenant. Guarantor's failure to comply with the foregoing covenant shall be a
material default of its obligations under this Guaranty, and in the event of
such a default, Fannie Mae immediately may draw on the Letter of Credit as
provided in the Pledge and LOC Agreement.

                 25.      RIGHTS CUMULATIVE.  The rights, powers and remedies

                                       30
   31
any Borrower and Fannie Mae. Any forbearance or failure to exercise, and any
delay by Fannie Mae in exercising, any right, power or remedy hereunder shall
not impair any such right, power or remedy or be construed to be a waiver
thereof, nor shall it preclude the further exercise of any such right, power or
remedy.

                 26.      GENERAL PROVISIONS. This Guaranty shall be binding
upon the respective heirs, legal representatives, successors and assigns of
