AMENDED AND RESTATED
OFFER TO PURCHASE

AIMCO Properties, L.P.

is offering to purchase any and all limited partnership units in

Riverside Park Associates Limited Partnership

for $64,429 per unit in CASH

Upon the terms and subject to the conditions set forth herein, we will accept any and all units validly tendered in response to our offer.

You will not pay any partnership transfer fees if you tender your units pursuant to this offer. You will pay any other fees or costs, including any transfer taxes.

Our offer price will be reduced for any distributions made or declared by your partnership after the date we commenced our offer and prior to the expiration of our offer.

OUR OFFER AND YOUR WITHDRAWAL RIGHTS WILL EXPIRE AT MIDNIGHT, NEW YORK CITY TIME, ON OCTOBER 29, 2007, UNLESS WE EXTEND THE DEADLINE.

The general partner of your partnership does not make any recommendation regarding whether you should accept this offer. You are encouraged to carefully review this 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 this offer.

See “Risk Factors” beginning on page 22 of this Offer to Purchase for a description of risk factors that you should consider in connection with our offer, including the following:

•  Upon completion of this offer, your partnership will terminate the registration of its limited partnership units under the Securities Exchange Act of 1934 and will no longer file reports with the Securities and Exchange Commission. As a result, it may become more difficult for you to obtain information about the partnership, its results of operations and financial condition.

•  There is no established or regular trading market for your units, nor is there a reliable standard for determining the fair market value of the units. Accordingly, our offer price may not represent the fair market value for your units.

•  Our offer price does not ascribe any value to potential future improvements in the fair market value or operating performance of your partnership’s property, including any prospective increase in value or property income that may result from the redevelopment of Riverside Park Apartments. Our offer price might be higher if it took into account any potential improvements in the fair market value or property income.

•  Our offer price is based on our internal valuation of the gross property value of your partnership’s property. However, a 2006 appraisal indicates a higher property value than our valuation and, accordingly, a higher value per unit. For a more detailed description of our valuation process, see “Special Factors — Valuation of Units.”

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of this transaction, passed upon the merits of this transaction, or passed upon the adequacy or accuracy of the disclosure in this Offer to Purchase. Any representation to the contrary is a criminal offense.

If you decide to accept our offer, you must complete and sign the enclosed letter of transmittal in accordance with the instructions thereto and mail or deliver the signed letter of transmittal and any other required documents to The Altman Group, Inc., which is acting as Information Agent in connection with our offer, at one of its addresses set forth on the back cover of this Offer to Purchase. Questions and requests for assistance or for additional copies of this Offer to Purchase or the letter of transmittal may also be directed to the Information Agent at (800) 217-9608.

•  Our offer price is not based on a third-party valuation and was not determined through any arms-length negotiations. Other persons might ascribe a value to your limited partnership units that is higher than our offer price. As a result, you might be able to sell your units to a third party at a price that exceeds our offer price.

•  Holding your units may result in greater future value. If your partnership’s property were sold in the future and the net proceeds from the sale were distributed to the limited partners, the amount of such distributions per unit might exceed our current offer price.

•  Your general partner and the property manager are affiliates of ours and, therefore, your general partner has substantial conflicts of interest with respect to our offer.

•  Continuation of your partnership will result in our affiliates continuing to receive management fees from your partnership. Such fees would not be payable if your partnership were liquidated.

•  We are making this offer with a view to making a profit and, therefore, there is a conflict between our desire to purchase your units at a low price and your desire to sell your units at a high price.

•  If we do not acquire all of the outstanding units in your partnership, it is possible that we may conduct a future offer at a higher price, although we have no obligation or current intention to do so.

•  For any units that we acquire from you, you will not receive any future distributions from operating cash flow of your partnership or upon a sale or refinancing of property owned by your partnership.

•  We and our affiliates own a majority of the outstanding units of your partnership. As a result, we and our affiliates control the voting decisions with respect to your partnership including, but not limited to, the removal of a general partner, most amendments to the partnership agreement and the sale of all or substantially all of your partnership’s assets.

•  The general partner makes no recommendation as to whether you should tender your units because each limited partner’s circumstances may differ from those of other limited partners.

The general partner does not make any recommendation regarding whether you should accept this offer. You are encouraged to carefully review this Offer to Purchase, and any other information available to you and to seek the advice of your independent lawyer, tax advisor and/or financial advisor with respect to your particular circumstances before deciding whether or not to accept this offer.

SUMMARY TERM SHEET

This summary term sheet highlights the material information regarding our offer, but it does not describe all of the details thereof. We urge you to read this entire Offer to Purchase, which contains the full details of our offer. We have also included in the summary term sheet references to the sections of this Offer to Purchase where a more complete discussion may be found. Unless otherwise indicated, references in this Offer to Purchase to “we,” “our,” “us” or “Aimco Operating Partnership” refer to AIMCO Properties, L.P., a Delaware limited partnership, and references to “general partner” refer to AIMCO/Riverside Park Associates GP, LLC, a Delaware limited liability company, the general partner of your partnership, Riverside Park Associates Limited Partnership. The general partner of the Aimco Operating Partnership is AIMCO GP, Inc., a Maryland corporation (“Aimco-GP”), which is a wholly owned subsidiary of Apartment Investment and Management Company, a Maryland corporation (“Aimco”). Aimco, Aimco-GP, the Aimco Operating Partnership, the general partner and the partnership are referred to herein, collectively, as the “Aimco Entities.”

•  The Offer.  Upon the terms and subject to the conditions set forth in this Offer to Purchase, we are offering to acquire any and all of the limited partnership units of Riverside Park Associates Limited Partnership, your partnership, for $64,429 per unit in cash. See “The Offer — Section 1. Terms of the Offer; Expiration Date.”

•  Termination of Registration.  On August 29, 2001, we commenced an offer to purchase any and all limited partnership units in your partnership. At the time of the commencement of the offer, there were more than 300 unitholders. Rule 13e-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the filing of a transaction statement with the Securities and Exchange Commission (the “SEC”) in connection with an offer that has a purpose or reasonable likelihood of causing securities registered under the Exchange Act to be held of record by fewer than 300 persons. If there are fewer than 300 holders of record of any class of registered securities, SEC rules permit the termination of registration and, accordingly, the cessation of the obligation to file periodic reports with the SEC under the Exchange Act. Rule 13e-3 is intended to provide investors with additional information in connection with a transaction that might result in a termination of such registration. In our August 2001 offer to purchase, we indicated that if the number of units tendered in response to the offer would otherwise result in there being fewer than 320 unitholders, we would prorate our purchases and acquire only 99% of the units tendered by each person. On this basis, we did not file a Rule 13e-3 transaction statement with the SEC for that offer. However, when the offer was completed, we inadvertently failed to implement the 99% proration, which resulted in there being less than 300 holders of limited partnership units. As a result of our failure to implement the 99% proration, our August 2001 offer violated Rule 13e-3. Upon subsequently becoming aware of the mistake, the managing general partner determined that the partnership should not terminate its registration under the Exchange Act, and would continue to file periodic reports with the SEC until such time, if any, as another transaction was effected that complied with the requirements of Rule 13e-3. In connection with this offer, we have filed a Rule 13e-3 transaction statement with the SEC, and the partnership will terminate registration after this offer is completed and will cease filing periodic reports with the SEC. As a result, it may become more difficult for you to obtain information about your partnership, its results of operations and financial condition. See “Special Factors — Purpose, Alternatives and Reasons for the Offer,” “— Effects of the Offer” and “— Future Plans and Proposals.” If the offer is not consummated for any reason, including any of the conditions described in “The Offer — Section 11. Conditions to the Offer,” the partnership will not terminate its registration.

•  Factors in Determining the Offer Price.  In determining the offer price per unit we principally considered:

•  your partnership’s property income for the 12 months ended June 30, 2007, net of an allowance for capital replacements;

•  our estimate of an appropriate capitalization rate for such property income;

•  the location, condition and debt structure of your partnership’s property;

•  the current economic conditions in the local market in which the property is located;

•  our estimate of the fees and expenses expected to be incurred by your partnership if its property is sold; and

•  your partnership’s other assets and liabilities.

•  Fairness of the Offer.  Although the Aimco Entities have interests that may conflict with those of the partnership’s unaffiliated limited partners, each of the Aimco Entities believes that the offer price and the offer are fair to the

1

unaffiliated limited partners of your partnership. This determination is based on the information and the factors set forth under “Special Factors — Fairness of the Offer.”

•  No General Partner Recommendation.  The general partner of your partnership makes no recommendation as to whether you should tender or refrain from tendering your units. Each limited partner should make his or her own decision whether or not to tender. You are encouraged to carefully review this 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 this offer. See “Special Factors — Fairness of the Offer.”

•  Who We Are.  We are AIMCO Properties, L.P., the operating partnership of Aimco, a New York Stock Exchange-listed company. We and our affiliates currently own 383.41 units, or 67.74% of the total outstanding units of your partnership. See “The Offer — Section 6. Information Concerning Us and Certain of Our Affiliates.”

•  Conflicts of Interest.  OP Property Management, LLC (which is our affiliate) receives fees for managing your partnership’s property, and the general partner of your partnership (which is our affiliate) is entitled to receive asset management fees and reimbursement of certain expenses involving your partnership and its property. As a result, a conflict of interest exists between continuing the partnership and receiving these fees, and liquidating the partnership and terminating these fees. See “Special Factors — Conflicts of Interest and Transactions with Affiliates” and “The Offer — Section 7. Certain Information Concerning Your Partnership.”

•  Tax Consequences.  Your sale of units in this offer will be a taxable transaction for federal income tax purposes. The consequences to each limited partner may vary and you should consult your tax advisor on the precise tax consequences to you. See “Special Factors — Material Federal Income Tax Matters.”

•  Expiration Date.  Our offer expires on October 29, 2007, unless extended, and you can tender your units until our offer expires. See “The Offer — Section 1. Terms of the Offer; Expiration Date.”

•  Right to Extend the Expiration Date.  We can extend the expiration date of the offer in our reasonable discretion. We reserve the right to extend the offer subject to customary conditions. In the event we extend the offer, we will issue a press release or other public announcement no later than 9:00 a.m., New York City time, on the next business day after the scheduled expiration date of the offer, in accordance with Rule 14e-1(d) of the Securities Exchange Act of 1934. See “The Offer — Section 5. Extension of Tender Offer Period; Termination; Amendment; No Subsequent Offering Period.”

•  How to Tender.  To tender your units, complete the accompanying letter of transmittal and send it, along with any other documents required by the letter of transmittal, to the Information Agent, The Altman Group, Inc., at one of the addresses set forth on the back of this Offer to Purchase. See “The Offer — Section 3. Procedure for Tendering Units.”

•  Withdrawal Rights.  You can withdraw your units at any time prior to the expiration of the offer, including any extensions. In addition, you can withdraw your units at any time on or after November 29, 2007 if we have not already accepted units for purchase and payment. If you properly withdraw all of the units you previously tendered in the offer, the corresponding letter of transmittal, including your release and assignment of future claims contained therein, will be deemed revoked and of no force or effect. See “The Offer — Section 4. Withdrawal Rights.”

•  How to Withdraw.  To withdraw your units, you need to send a notice of withdrawal to the Information Agent, identifying yourself and the units to be withdrawn. See “The Offer — Section 4. Withdrawal Rights.”

•  Availability of Funds.  We intend to pay the purchase price for any units tendered from our existing cash balances or borrowings under our line of credit. See “The Offer — Section 9. Source of Funds.”

•  Conditions to the Offer.  There are a number of conditions to our offer, including the absence of competing tender offers, that there be no material change with respect to our financial condition and the absence of certain changes in the financial markets. See “The Offer — Section 11. Conditions to the Offer.”

•  Remaining as a Limited Partner.  If you do not tender all of your units, you will remain a limited partner in your partnership. Consummation of the offer will not affect the operations, business or financial position of your partnership. However, it is expected that, after this offer, the partnership will terminate registration under the Exchange Act and will cease to file periodic reports with the SEC. As a result, it may become more difficult for you to obtain information about the partnership, its results of operations and financial condition. See “Special Factors — Effects of the Offer.”

2

•  No Subsequent Offering Period.  We do not currently intend to have a subsequent offering period after the expiration date of the initial offering period (including any extensions). See “The Offer — Section 5. Extension of Tender Offer Period; Termination; Amendment; No Subsequent Offering Period.”

•  Additional Information.  For assistance in tendering your units, please contact our Information Agent at one of the addresses or the telephone number set forth on the back cover page of this Offer to Purchase.

SPECIAL FACTORS

In reviewing this offer and before deciding whether or not to tender any of your units, you should consider carefully the information discussed in this Special Factors section of this Offer to Purchase.

Purpose, Alternatives and Reasons for the Offer

Purpose.  We are in the business of acquiring direct and indirect interests in apartment properties such as the property owned by your partnership. Our purpose in undertaking the offer at this time is to increase our ownership interest in your partnership.

Alternatives.  Before deciding to proceed with this offer, the Aimco Entities considered alternative transactions that would result in the Aimco Operating Partnership acquiring an increased ownership in the partnership. The following is a brief discussion of the alternatives the Aimco Entities considered:

Merger.  The Aimco Entities considered a merger of the partnership with a wholly owned subsidiary of the Aimco Operating Partnership in which unaffiliated limited partners would receive a cash payment, but rejected this alternative because:

•  the merger would not allow individual limited partners to decide whether or not they wanted to participate; and

•  the merger would not be on an arms-length basis and would therefore create a risk that the managing general partner would be subject to claims by limited partners that it had breached its fiduciary duties to the limited partners by authorizing a merger on terms that were not fair to limited partners.

Exchange Offer.  The Aimco Entities considered an offer to exchange units in your partnership for units of limited partnership interest in the Aimco Operating Partnership, but rejected this alternative because:

•  an exchange offer would be more expensive and take longer than a cash offer; and

•  our historical experience has been that when we have offered limited partners of other partnerships an opportunity to receive cash or units of limited partnership interest in the Aimco Operating Partnership, the limited partners who tendered usually preferred the cash option.

Reasons.  We have decided to make the offer at this time because we think interests in the partnership will be a good investment. We believe that the pending redevelopment of Riverside Park Apartments is likely to result in improvements in operating income and an increase in value of the property, and we would like to increase our proportionate benefit from those improvements.

The offer is being made in compliance with the filing, dissemination and disclosure requirements of Rule 13e-3 under the Exchange Act. Rule 13e-3 under the Exchange Act requires the filing of a transaction statement with the SEC in connection with an offer that has a purpose or reasonable likelihood of causing securities registered under the Exchange Act to be held of record by fewer than 300 persons. If there are fewer than 300 holders of record of any class of registered securities, SEC rules permit the termination of registration and, accordingly, the cessation of the obligation to file periodic reports with the SEC under the Exchange Act. Rule 13e-3 is intended to provide investors with additional information in connection with a transaction that might result in a termination of such registration. On August 29, 2001, we commenced an offer to purchase any and all limited partnership units in your partnership. At the time of the commencement of the offer, there were more than 300 unitholders. In the August 2001 offer to purchase, we indicated that if the number of units tendered in response to the offer would otherwise result in there being fewer than 320 unitholders, we would prorate our purchases and acquire only 99% of the units tendered by each person. On this basis, we did not file a Rule 13e-3 transaction statement with the SEC for that offer. However, when the offer was completed, we inadvertently failed to implement the 99% proration, which resulted in there being less than 300 holders of

3

limited partnership units. As a result of our failure to implement the 99% proration, our August 2001 offer violated Rule 13e-3. Upon subsequently becoming aware of the mistake, we determined that the partnership should not terminate its registration under the Exchange Act, and would continue to file periodic reports with the SEC until such time, if any, as another transaction was effected that complied with the requirements of Rule 13e-3. In connection with this offer, we have filed a Rule 13e-3 transaction statement with the SEC.

Effects of the Offer

Expected Benefits of the Offer to Unaffiliated Limited Partners.  The Aimco Entities believe that the offer has the following principal advantages to the unaffiliated limited partners:

Liquidity.  There is no established trading market for the limited partnership units, and the offer provides liquidity for tendering limited partners.

Option to Retain Units.  The offer allows each limited partner the opportunity to tender any or all of his or her units, or to retain all of their units. Limited Partners who retain their units will participate in future distributions from the partnership, which are expected to increase as a result of the pending redevelopment, as well as future increases in property value.

Elimination of Costs Associated with SEC Filing Requirements.   The partnership will terminate registration after this offer is completed, and will cease filing periodic reports with the SEC. As a result, the partnership will no longer incur costs associated with preparing, auditing and filing these reports. We estimate these expenses to be approximately $23,000 per year. This represents approximately 4.00% of the partnership’s general and administrative expenses and 0.18% of the partnership’s total expenses (based on 2006 expenses of approximately $565,000 and $13,091,000, respectively).

Expected Benefits of the Offer to the Partnership.  The Aimco Entities believe that the offer has the following principal advantages to your partnership:

Elimination of Costs Associated with SEC Filing Requirements.   The partnership will terminate registration after this offer is completed, and will cease filing periodic reports with the SEC. As a result, the partnership will no longer incur costs associated with preparing, auditing and filing these reports. We estimate these expenses to be approximately $23,000 per year. This represents approximately 4.00% of the partnership’s general and administrative expenses and 0.18% of the partnership’s total expenses (based on 2006 expenses of approximately $565,000 and $13,091,000, respectively).

Expected Benefits of the Offer to the Aimco Entities.  The Aimco Entities believe that the offer has the following principal advantages to the Aimco Entities (excluding your partnership):

Increased Interest in Your Partnership’s Net Income.  If we acquire all of the units that we are seeking in the offer, our interest in your partnership’s net income (which was a net gain of $363,000 for the six months ended June 30, 2007) and net book value (($21,785,000) as of June 30, 2007) will increase to 100%. Aimco, through its wholly owned subsidiaries, Aimco-GP and AIMCO-LP, Inc., holds approximately a 91% interest in the Aimco Operating Partnership as of June 30, 2007. As a result, the Aimco Operating Partnership will receive a greater proportionate benefit from any future increase in property income, as well as appreciation of the property, after consummation of the offer.

Increased Participation in Future Distributions.  If we acquire units in the offer, we will increase our proportionate participation in any subsequent distributions to limited partners.

Expected Detriments of the Offer to Unaffiliated Limited Partners.  The Aimco Entities believe that the offer has the following principal detriments to the unaffiliated limited partners:

No Separate Representation of Limited Partners.  The general partner is our subsidiary. In structuring the offer and the consideration, no one separately represented the interests of the limited partners and the offer price was determined without an arms-length negotiation. Although the general partner has a fiduciary duty to the limited partners, it also has responsibilities to its sole member, which is an affiliate of Aimco, that could conflict with the interests of the limited partners. The general partner did not appoint, nor did we ask it to appoint, a party to represent only the interests of the limited partners. Our offer price could be higher if it were subject to independent negotiations.

4

Adverse Effect on Marketability.  If a substantial number of units are purchased pursuant to the offer, the result will be a reduction in the number of limited partners in your partnership. A reduction in the number of securityholders might result in a reduction in the liquidity and volume of activity in the trading market for the partnership units.

Termination of SEC Registration.  The units are currently registered under Section 12(g) of the Exchange Act, which means, among other things, that your partnership is required to file periodic reports with the SEC and to comply with the SEC’s proxy rules. Upon consummation of this offer, your partnership will terminate the registration of its limited partnership units under Section 12(g) of the Exchange Act. Upon such termination of registration, your partnership will no longer file reports with the SEC, such as annual reports on Form 10-KSB containing annual audited financial statements and quarterly reports on Form 10-QSB containing unaudited quarterly financial statements. Additionally, your partnership will not be required to provide current reports on Form 8-K describing certain material events. In addition, it will no longer be subject to certain provisions of the Sarbanes-Oxley Act of 2002 and the liability provisions of the Exchange Act. As a result, you regularly will have access only to the limited information that your partnership’s agreement of limited partnership requires your managing general partner (which is our subsidiary) to provide to unitholders each year, which consists primarily of tax information. In particular, you will continue to receive a Schedule K-1 as well as audited financial statements with respect to your partnership each year. A Schedule K-1 is an information statement that contains tax information for the fiscal year of your partnership, such as your allocation of income, deductions, credits, gains and losses of your partnership for federal income tax purposes. In comparison, the periodic reports filed by your partnership under the Exchange Act contain your partnership’s annual and quarterly financial statements prepared in accordance with generally accepted accounting principles. These periodic reports filed under the Exchange Act also include information regarding your partnership’s business and property and a discussion regarding your partnership’s financial condition and results of operations. The lack of filing periodic reports could affect the already limited secondary market which currently exists for units in your partnership and may result in others not tendering for such units.

Reduce Participation in Future Distributions.  For any units that we acquire from you, you will not receive any future distributions from operating cash flow of your partnership or upon a sale or refinancing of property owned by your partnership. Our offer price does not ascribe any value to potential future improvements in the fair market value or operating performance of your partnership’s property that may result from the proposed redevelopment of Riverside Park Apartments.

Taxable Gain to Limited Partners.  For U.S. federal income tax purposes, your sale of units for cash will be a taxable sale, with the result that you will recognize taxable gain or loss measured by the difference between the amount realized on the sale and your adjusted tax basis in the units of limited partnership interest of your partnership that you transfer to us. The “amount realized” with respect to a unit of limited partnership interest that you transfer to us will be equal to the sum of the amount of cash received by you for the unit sold pursuant to the offer plus the amount of partnership liabilities allocable to your unit. Depending on your basis in the units and your tax position, your tax liability resulting from a sale of units to us pursuant to the offer could exceed our offer price. The particular tax consequences for you of our offer will depend upon a number of factors related to your tax situation, including your adjusted tax basis in the units you transfer to us, whether you dispose of all of your units and whether you have available suspended passive losses, credits or other tax items to offset any gain recognized as a result of your sale of your units. We may also be required by federal, state or local tax laws to withhold a portion of our offer price. Because the income tax consequences of tendering units will not be the same for everyone, you should consult your tax advisor to determine the tax consequences of the offer to you.

Expected Detriments of the Offer to the Partnership.  The Aimco Entities believe that the offer has the following principal detriments to your partnership:

No Separate Representation of Limited Partners.  The general partner is our subsidiary. In structuring the offer and the consideration, no one separately represented the interests of the limited partners and the offer price was determined without an arms-length negotiation. Although the general partner has a fiduciary duty to the limited partners, it also has responsibilities to its sole member, which is an affiliate of Aimco, that could conflict with the interests of the limited partners. The general partner did not appoint, nor did we ask it to appoint, a party to represent only the interests of the limited partners. The offer price could be higher if it were subject to independent negotiations.

5

Expected Detriments of the Offer to the Aimco Entities.  The Aimco Entities believe that the offer has the following principal detriments to the Aimco Entities (excluding your partnership):

Increased Participation in Any Future Losses.  If we acquire all of the units that we are seeking in the offer, as the sole limited partner of the partnership, the Aimco Operating Partnership will bear the burden of all future losses and decreases in value of Riverside Park Apartments.

Increased Burden of Property Management Fees.  If we acquire all of the units that we are seeking in the offer, an affiliate of the Aimco Operating Partnership will continue to receive a property management fee on Riverside Park Apartments, but such fee will be borne completely by the Aimco Operating Partnership and will no longer be shared with the limited partners.

Accounting Treatment.  Upon consummation of the offer, we will account for our investment in any acquired units under the purchase method of accounting. There will be no effect on the financial statements of your partnership as a result of the offer.

Material Federal Income Tax Matters

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

You should consult your tax advisor regarding the United States federal, state, local and foreign tax consequences of selling the interests in your partnership represented by your units pursuant to our offer or of a decision not to sell in light of your specific tax situation.

Tax Consequences to Limited Partners Tendering Units for Cash.  The sale of a unit of limited partnership interest pursuant to this offer will be a taxable transaction for United States federal income tax purposes. You will recognize gain or loss on a sale of a unit of limited partnership interest of your partnership equal to the difference, if any, between (i) your “amount realized” on the sale and (ii) your adjusted tax basis in the unit sold. The “amount realized” with respect to a unit will be equal to the sum of the amount of cash received by you for the unit sold pursuant to the offer plus the amount of partnership liabilities allocable to your unit (as determined under Section 752 of the Code). Thus, your tax liability resulting from a sale of a unit could exceed the cash received upon such sale.

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

6

your gain recognized with respect to a unit pursuant to the offer will exceed the cash proceeds realized upon the sale of such unit, and may result in a tax liability to you that exceeds the cash received upon such sale.

Character of Gain or Loss Recognized Pursuant to the Offer.  Except as described below, the gain or loss recognized by you on a sale of a unit pursuant to the offer generally will be treated as a long-term capital gain or loss if you held the unit for more than one year. Long-term capital gains recognized by individuals and certain other noncorporate taxpayers generally will be subject to a maximum United States federal income tax rate of 15%. If the amount realized with respect to a unit of limited partnership interest of your partnership that is attributable to your share of “inventory items” or “unrealized receivables” of your partnership exceeds the tax basis attributable to those assets, such excess will be treated as ordinary income. Among other things, “unrealized receivables” include depreciation recapture for certain types of property. In addition, the maximum United States federal income tax rate applicable to persons who are noncorporate taxpayers for net capital gains attributable to the sale of depreciable real property (which may be determined to include an interest in a partnership such as your units) held for more than one year is currently 25% (rather than 15%) with respect to that portion of the gain attributable to depreciation deductions previously taken on the property. Certain limitations apply to the use of capital losses.

If you tender a unit of limited partnership interest of your partnership in the offer, you will be allocated a share of partnership taxable income or loss for the year of tender with respect to any units sold. You will not receive any future distributions on units tendered on or after the date on which such units are accepted for purchase and, accordingly, you may not receive any distributions with respect to such accreted income. Such allocation and any partnership cash distributions to you for that year will affect your adjusted tax basis in your unit and, therefore, the amount of your taxable gain or loss upon a sale of a unit pursuant to the offer.

Passive Activity Losses.  The passive activity loss rules of the Code limit the use of losses derived from passive activities, which generally include investments in limited partnership interests such as your units. An individual, as well as certain other types of investors, generally may not use losses from passive activities to offset nonpassive activity income received during the taxable year. Passive losses that are disallowed for a particular tax year are “suspended” and may be carried forward to offset passive activity income earned by the investor in future taxable years. In addition, such suspended losses may be claimed as a deduction, subject to other applicable limitations, upon a taxable disposition of the investor’s interest in such activity. Accordingly, if your investment in your units is treated as a passive activity, you may be able to reduce gain from the sale of your units pursuant to the offer with passive losses in the manner described below. You are urged to consult your tax advisor concerning whether, and the extent to which, you have available “suspended” passive activity losses from your partnership or other investments that may be used to reduce gain from the sale of units pursuant to the offer.

Release and Assignment of Claims.  If you tender units in this offer, a portion of the price paid to you may be deemed a payment for your release and assignment of claims. The proper treatment for federal income tax purposes of your receipt of any deemed payments for your release and assignment of claims is uncertain. No opinion or assurance can be given that the IRS will not challenge the treatment of any deemed payments for your release and assignment of claims as additional consideration for the units, and assert that such amount should be treated as an ordinary income payment in exchange for your release and/or assignment of current and future claims. You should consult your tax advisor regarding the tax consequences to you with respect to your right to, and your receipt of, any deemed payments for your release and assignment of claims.

Information Reporting, Backup Withholding and FIRPTA.  If you tender any units, you must report the transaction by filing a statement with your United States federal income tax return for the year of the tender which provides certain required information to the IRS. The paying agent may also be required to report the transaction to the IRS. To prevent the possible application of United States federal back-up withholding tax (currently, 28%) with respect to the payment of the offer consideration, you are generally required to provide us a completed Substitute IRS Form W-9, included with the letter of transmittal. Back-up withholding is not an additional tax. Any amounts withheld under the back-up withholding rules may be refunded or credited against your United States federal income tax liability, if any, provided that the required information is furnished to the IRS.

Gain realized by a foreign person on the sale of a unit pursuant to the offer will be fully subject to United States federal income tax under the Foreign Investment in Real Property Tax Act of 1980. In addition, if we acquire an interest held by a foreign person, we will be required to deduct and withhold 10% of the amount realized by such foreign person on the disposition. Amounts withheld would be creditable against a foreign person’s United States federal income tax liability and, if in excess thereof, a refund could be claimed from the IRS by filing a United States income tax return. Foreign persons must provide the appropriate IRS Form W-8 to the Information Agent.

7

State and Local Withholding.  If you tender any units pursuant to this offer, we may be required under state or local tax laws to deduct and withhold a portion of our offer price. You should consult your tax advisor concerning whether any state or local withholding would be required on a disposition of your units and whether such amounts may be available to you as a credit on your state or local tax returns.

Tax Consequences to the General Partner of Your Partnership and its Affiliates, including the Aimco Operating Partnership.  The sale of your units pursuant to this offer will not be a taxable transaction for the general partner of your partnership or its affiliates, including the Aimco Operating Partnership. Consequently, the general partner of your partnership and its affiliates will not recognize gain or loss in connection with this offer.

Valuation of Units

Determination of Offer Price.  Our offer price is based on our estimate of the proceeds that would be available for distribution to limited partners in the event of a liquidation of your partnership’s property. We determined our offer price by estimating the net equity value of your partnership based on our valuation of your partnership’s property using the direct capitalization method. Although this method is a widely accepted way of valuing real estate, there are a number of other methods available to value real estate, each of which may result in different valuations of a property. The direct capitalization method involves applying a capitalization rate to property income. A capitalization rate is a percentage commonly applied to property income by purchasers of real estate to determine the present value of income-producing property. The lower the capitalization rate, the higher the value produced, and the higher the capitalization rate, the lower the value produced. We used the capitalization rate provided by Property & Portfolio Research (“PPR”), an independent real estate research and investment consulting firm, as of June 30, 2007 for the northern Virginia market. This capitalization rate was 4.92%.

PPR is an independent real estate research and investment consulting firm that employs a large staff of economists and real estate industry experts. PPR produces a quarterly database of fundamental real estate data in various U.S. markets such as return on income, vacancy rates and capitalization rates. Aimco/Bethesda pays PPR an annual subscription fee of $90,000 for access to the database. During the prior two years, no material relationship has existed between PPR and your partnership or any of its affiliates, including Aimco Properties, L.P.

Property income is the difference between the revenues from the property and related costs and expenses, excluding income derived from sources other than regular activities and before income deductions. Income deductions include interest, income taxes, prior-year adjustments, charges to reserves, write-offs of intangibles, adjustments arising from major changes in accounting methods and other material and nonrecurring items. In this respect, property income differs from net income disclosed in the partnership’s financial statements, which does not exclude these income sources and deductions.

We determined our offer price as follows:

•  First, we estimated the gross value of your partnership’s property using the direct capitalization method. For the 12 month period ended June 30, 2007, total property income was approximately $7,300,000. We deducted from this amount a capital replacement reserve of $350 per apartment unit (approximately $430,000) to arrive at net property income of approximately $6,870,000. We then divided net property income by the capitalization rate of 4.92% to derive an estimated gross property value of approximately $139,600,000, which we rounded up to $140,000,000.

•  Second, we calculated the net equity value of your partnership by adding to the estimated gross property value the value of the non-real estate assets of your partnership and deducting its liabilities, including mortgage debt, debt prepayment penalties, debt owed by your partnership to the general partner or its affiliates, accounts payable and accrued expenses and certain other costs, including a contingency reserve that would be set aside for any expenses attributable to the property that are payable subsequent to the sale of the property.

•  Finally, we allocated 99% of this net equity value to limited partners, which is the percentage of net proceeds that would be distributed to limited partners in the event of a liquidation of your partnership under the partnership agreement, and divided this by the number of outstanding limited partnership units to determine a net equity value per unit.

The net equity value per unit determined in this manner, as indicated below, results in an estimated net equity value per unit of $64,429.

Comparison of Offer Price to Alternative Consideration.  To assist holders of units in evaluating the offer, your general partner, which is our affiliate, has compared the offer price against: (a) other cash tender offer prices and private purchase prices since January 1, 2004 that the general partner has knowledge of, and (b) prices at which the units have been sold on the secondary market that the general partner has knowledge of. The results of this comparison are summarized in the chart below.

Comparison Table	Per Unit
Cash offer price	$	64,429
Alternatives
Highest cash tender offer or private purchase price	$	22,220	(1)
Highest price on secondary market	$	67,523	(2)

(1)	Highest prior tender offer or private purchase since January 1, 2004. See discussion below regarding private purchase of 0.5 units for a purchase price of $22,220.
(2)	Highest sale price on the secondary market since January 1, 2004, as reported by Direct Investment Spectrum and American Partnership Board.

Prior Tender Offers and Private Purchases.  We have not conducted any prior tender offers for units in your partnership in the past three years. On March 11, 2005, we purchased 0.5 units in your partnership for a purchase price of $22,220. We have not purchased any additional units in your partnership in the past three years. From time to time, we become aware of tender offers by unaffiliated third parties to acquire units in your partnership in exchange for cash. Although we are not always informed when such third party offers commence or have occurred, we are not aware of any tender offers by unaffiliated third parties that have been commenced or completed in the past three years.

Prices on Secondary Market.  Secondary market sales information is not a reliable measure of value because of the limited number of any known trades. Except for offers made by us and unaffiliated third parties, privately negotiated sales and sales through intermediaries are the only means that may be available to a limited partner to sell his or her units because the units are not listed or traded on any securities exchange or quoted on Nasdaq, on the Electronic Bulletin Board, or in “pink sheets.” Secondary sales activity for the units, including privately negotiated sales, has been limited and sporadic.

Set forth below are the high and low secondary sales prices of units during the year ended December 31, 2007 (through May 31), the year ended December 31, 2006 and the year ended December 31, 2005, as reported by Direct Investments Spectrum (formerly known as The Partnership Spectrum), which is an independent, third-party source. The gross sales prices reported by Direct Investments Spectrum do not necessarily reflect the net sales proceeds received by sellers of units, which often are reduced by commissions and other secondary market transaction costs. We do not know whether the information compiled by Direct Investments Spectrum is accurate or complete.

Sales Prices of Partnership Units, as Reported by Direct Investments Spectrum

	High		Low
Year Ended December 31, 2007 (through May 31):	$	56,000	$	54,000
Year Ended December 31, 2006:	$	67,523	$	49,000
Year Ended December 31, 2005:	$	55,000	$	52,000

No high and low sales prices of units during the year ended December 31, 2004 were reported by either Direct Investments Spectrum or the American Partnership Board, which is the only other independent, third-party source from which we currently have information regarding secondary sales, nor did the American Partnership Board report such sales prices during the years ended December 31, 2007 (through August 31), December 31, 2006 and 2005. Other sources may contain prices for the units that equal or exceed the sales prices reported by Direct Investments Spectrum and The American Partnership Board.

Summary of 2006 Independent Appraisal

Set forth below is a summary of the 2006 appraisal conducted by Robert D. Wright, MAI (“Wright”). The summary below includes a description of the procedures followed by Wright, his findings and recommendations, bases for and methods of arriving at such findings and recommendations, instructions received from, or limitations imposed by (if any), us or our affiliates, and the conclusions reached by Wright in appraising the value of Riverside Park Apartments. Wright concluded that the market value of the fee simple estate of Riverside Park Apartments, as of May 25, 2006, was $149,000,000. This report is provided for disclosure purposes of a historic event and does not represent the current conditions at the property nor current market value.

Selection and Qualifications of Independent Appraiser.  Wright was hired by Reilly Mortgage Group, Inc. (the “Lender”), in connection with the refinancing of mortgages encumbering your partnership’s property, to estimate the market value of the fee simple estate of Riverside Park Apartments as of May 25, 2006, and to prepare a real estate appraisal report presenting the data, reasoning and analyses used in the appraisal process to develop an opinion of value. Wright is a Certified General Real Estate Appraiser in the state of Virginia and has been a self-employed appraiser since 1981.

Wright performed a complete appraisal of Riverside Park Apartments. Wright has represented that his report was prepared in conformance with the Code of Ethics and Standards of Professional Appraisal Practice of the Appraisal Institute and the Appraisal Foundation and Freddie Mac appraisal guidelines and the appraisal requirements of the Lender. Neither the assignment to make the appraisal nor the compensation for it was contingent upon the appraised value of the property. Wright’s analysis was based on an inspection of the property, a review of available operating history and consideration of local market data on or about May 25, 2006. The summary set forth below describes the material conclusions reached by Wright based on the values determined under the valuation approaches and subject to the assumptions and limitations described below.

Summary of Valuation Approaches and Methodologies Employed.  The following summary describes the material approaches and analyses employed by Wright in preparing the appraisal. Wright relied on the Income Approach to valuation and the Sales Comparison Approach.

The purpose of the Income Approach is to value a property by analyzing the anticipated future income and expenses of the property over an anticipated investment (or holding) period. This approach is widely applied in appraising income-producing properties. Under this approach, the value of a property is estimated by deducting an appropriate vacancy and collection allowance rate and all applicable expenses from the property’s anticipated gross annual income to arrive at a projected net operating income (“NOI”), which is then capitalized at an interest rate (the capitalization rate) commensurate with the risk inherent in the ownership of the property. The reliability of this approach is dependent on the reliability of the net income estimate and the capitalization rate. There are two primary income capitalization methods: (1) direct capitalization analysis, which converts a single year’s NOI into an indication of value and (2) discounted cash flow analysis, which estimates the value

10

of a property by discounting to present value the forecasted net income of the property over the course of an anticipated investment period and the estimated proceeds from a hypothetical sale of such property at the end of such investment period. Wright utilized only the direct capitalization method. Freddie Mac Appraisal Guidelines prohibit the use of discounted cash flow analysis in appraisals to be submitted to Freddie Mac.

The estimated value of a property derived using the Sales Comparison Approach represents the probable price at which a property would be sold by a willing seller to a willing buyer at arms-length as of the date of value. The Sales Comparison Approach analyzes recent sales of comparable improved properties in surrounding or competing areas to derive units of comparison that are then used to indicate a value for the subject property. Adjustments are made to the sales prices of comparable properties for differences from the subject property, such as terms of financing, date of sale, location and physical characteristics. Obtaining data with a high degree of comparability is most important for this method. The reliability of this method is dependent upon the availability of comparable sales data, the verification of such sales data, the degree of comparability, the extent of adjustment necessary for differences and the absence of non-typical conditions affecting the sales prices.

Valuation Under Income Approach.  Under the Income Approach, Wright performed a direct capitalization analysis to derive a value for Riverside Park Apartments, which involved (1) calculating potential gross annual income from the property; (2) estimating vacancy and credit loss to arrive at the property’s annual effective gross income (“EGI”); (3) estimating operating expenses to arrive at the stabilized NOI; (4) developing the overall capitalization rate; and (5) dividing NOI by the overall capitalization rate to arrive at a value for Riverside Park Apartments.

Wright performed a market rent analysis for the property to derive a projected annual rental income. Market rents were estimated based on the property’s rent roll, recent leasing history, street rents and market data. Wright calculated EGI by adding apartment rental collections to other income and then making adjustments, including adjustments based on an estimated stabilized physical vacancy of 5.5% and a 1.0% collection loss. Under this analysis, Wright arrived at an EGI of $15,658,906. Once the EGI was established, operating expenses were deducted from the EGI in order to arrive at an NOI of approximately $8,940,506. Wright performed a pro forma analysis of revenue and expenses for the property to derive the subject property’s stabilized NOI. Wright relied on the subject’s historical operating statements from January 2002 through April 2006 for this estimate. Wright derived an overall capitalization rate of 6.0% based upon analysis of comparable sales, which ranged from approximately 5.4% to 7.3%, and a synthesis of mortgage interest and equity dividend rates, which ranged from approximately 5.5% to 6.15%. Using an overall capitalization rate of 6.00%, Wright determined that the direct capitalization method indicated a value of $149,000,000 (after rounding) for Riverside Park Apartments.

Valuation Under Sales Comparison Approach.  Wright compared Riverside Park Apartments with six multifamily apartment complexes with similar characteristics that were sold between March 2004 and December 2005 and located in Riverside Park’s real estate market area. Due to the variations between properties, these sales were compared to the property on the basis of sale price per unit and a gross income multiplier calculation. The unadjusted sales prices of the comparable sale property ranged from $97,030 to $176,251 per unit. Emphasizing these comparables, Wright considered a value indicator of $121,000 per unit to be appropriate. With 1,222 units at $121,000 per unit, Wright determined the market value of Riverside Park Apartments using the Sales Comparison Approach to be $147,900,000 (after rounding). Wright used a gross income multiplier of 8.9, which was based on the relationship between each property’s income potential and sale price. With the potential gross income of $16,631,175 and a gross income multiplier of 8.9, Wright determined the property’s market value using the gross income multiplier to be $148,000,000 (after rounding). Wright gave equal weight to the per unit value calculation and the gross income multiplier value calculation to arrive at a market value for Riverside Park Apartments of $147,900,000 under the Sales Comparison Approach. Wright assumed a marketing and exposure period of six to twelve months.

Reconciliation of Values and Conclusions of Appraisal.  The final step in the appraisal process was to reconcile the Sales Comparison Approach and the Income Approach values to arrive at a final value conclusion. The reconciliation of the two approaches involved weighing the valuation techniques in relation to their substantiation by market and other sources of data, the relativity and applicability of the approaches to the property type, and the purpose of the valuation. Wright concluded a market value of $147,900,000 under the Sales Comparison Approach and a market value of $149,000,000 under the Income Approach. After reconciling the various factors, Wright determined a final estimate of market value of $149,000,000 for Riverside Park Apartments as of May 25, 2006 in its appraisal report dated June 28, 2006.

Assumptions, Limitations and Qualifications of Wright’s Valuation.  This appraisal was prepared for use by the Lender for mortgage underwriting purposes. Other uses of this appraisal were not intended. This appraisal does not reflect present

11

conditions at the subject property nor a present valuation. In preparing the appraisal, Wright relied on the accuracy and completeness of all information supplied or otherwise made available to him. As of May 25, 2006, the date of Wright’s inspection, a substantial renovation of the property was in process. At the Lender’s request, the appraisal assumed habitable condition prior to renovation, and did not consider the cost to complete the renovation of units already gutted for rehabilitation. Additionally, the property’s actual physical vacancy rate (20.6%) was elevated as of the date of valuation since the owners had commenced lease terminations to create vacancies for the renovation. At the Lender’s request, stabilized occupancy was assumed without adjustment for rent loss during lease-up. This appraisal was completed without the benefit of current engineering and environmental site assessment reports. If subsequently completed reports revealed the need for significant immediate repairs or if significant environmentally hazardous conditions exist, this valuation would be adversely impacted. Except as set forth herein, neither we, any of our affiliates nor the partnership imposed any conditions or limitations on the scope of Wright’s investigation or the methods and procedures to be followed in preparing the appraisal. In addition to the previously stated requests by the Lender regarding assumptions of habitable condition and stabilized occupancy, Wright’s appraisal report and opinion of value were made subject to the following assumptions and limiting conditions:

•  the legal description used in the appraisal report is assumed to be correct;

•  no survey of the property was made by Wright and no responsibility is assumed in connection with such matters. Sketches in the report are included only to assist the reader in visualizing the property;

•  no responsibility is assumed for matters of a legal nature affecting title to the property nor is an opinion of title rendered. The title was assumed to be good and marketable;

•  information furnished by others is assumed to be true, correct and reliable. A reasonable effort was made to verify such information; however, Wright assumed no responsibility for its accuracy;

•  all mortgages, liens, encumbrances, leases and servitude were disregarded unless specified otherwise in the report;

•  the property was appraised as though under responsible ownership and competent management;

•  it was assumed that there were no hidden or unapparent conditions of the property, subsoil, or structures which would render it more or less valuable. No responsibility was assumed for such conditions or for engineering which may be required to discover such factors;

•  it was assumed that there was full compliance with all applicable federal, state and local environmental regulations and laws as of the date of the appraisal unless non-compliance was stated, defined and considered in the appraisal report;

•  it was assumed that all applicable zoning and use regulations and restrictions were complied with, unless a non-conformity was been stated, defined and considered in the appraisal report;

•  it was assumed that all required licenses, consents or other legislative or administrative authority from any local, state or national governmental or private entity or organization were or could be obtained or renewed for any use on which the value estimate contained in the appraisal report is based;

•  it was assumed that the utilization of the land (and improvements) was within the boundaries or property lines of the property described and that there was no encroachment or trespass unless noted within the report;

•  unless otherwise stated in the appraisal report, the existence of radon air pollution or hazardous material, which may or may not have been present on the property, was not observed by the appraiser. The appraiser was not qualified to detect such substances. The presence of substances such as asbestos, ureaformaldehyde foam insulation, or other potentially hazardous materials or environmental hazards may affect the value of the property. The value estimate was predicated on the assumption that there was no such material or condition on or in the property that would have caused a loss in value;

•  the appraiser will not be required to give testimony or appear in court because of having made this appraisal, with reference to the property in question, unless arrangements have been previously made;

•  possession of this report, or a copy thereof, does not carry with it the right of publication. It may not be used for any purpose by any person other than the party to whom it is addressed without the written consent of the appraiser, and in any event only with the proper written qualifications and only in its entirety;

12

•  the distribution of the total valuation in this report between land and improvements applies only under the reported highest and best use of the property. The allocations of value for land and improvements must not be used in conjunction with any other appraisal and are invalid if so used;

•  one (or more) of the signatories of this appraisal report is a member (or candidate) of the Appraisal Institute. The bylaws and regulations of the Institute require each member and candidate to control the use and distribution of each appraisal report signed by such member or candidate. Therefore, except as hereinafter provided, the party for whom this appraisal was prepared may distribute copies of this appraisal report, in its entirety, to such third parties as may be selected by the party for whom this appraisal report was prepared; however, selected portions of this appraisal report shall not be given to third parties without the prior written consent of the signatories of this appraisal report; and

•  in the event that this appraisal contains a valuation of an estate in land that is less than the entire fee simple estate, it is noted that (i) the value reported for such estate relates to a fractional interest only in the real estate involved; and, (ii) the value of this fractional interest plus the value of all other fractional interests may or may not equal the value of the entire fee simple estate considered as a whole.

Availability of Appraisal Report.  You may obtain a full copy of Wright’s appraisal upon request, without charge, by contacting the Information Agent at one of the addresses or the telephone number on the back cover of this Offer to Purchase. Copies of the appraisal for the property are also available for inspection and copying at the principal executive offices of the partnership during regular business hours by any interested unitholder or his or her designated representative at his or her cost.

Summary of 2005 Independent Appraisal

Set forth below is a summary of the independent appraisal of Riverside Park Apartments conducted in October 2005 by KTR. The summary below includes a description of the procedures followed by KTR, its findings and recommendations, bases for and methods of arriving at such findings and recommendations, instructions received from, or limitations imposed by (if any), us or our affiliates, and the conclusions reached by KTR in appraising the value of Riverside Park Apartments. KTR concluded that the market value of the leased fee simple estate of Riverside Park Apartments, as of October 24, 2005, is $122,300,000.

Selection and Qualifications of Independent Appraiser.  We hired KTR to estimate the market value of the fee simple estate of Riverside Park Apartments, free and clear of financing, as of October 24, 2005, and to prepare a real estate appraisal report presenting the data, reasoning and analyses used in the appraisal process to develop its opinion of value. KTR is a leading real estate valuation, engineering and environmental due diligence firm and employs one of the largest in-house staffs of appraisers and analysts. KTR is an affiliate of Newmark Knight Frank, a full service, global commercial real estate service provider headquartered in New York.

We paid KTR a fee of $5,514 for the appraisal. During the prior two years, no material relationship has existed between KTR and your partnership or any of its affiliates, including Aimco Properties, L.P, although KTR has performed real estate appraisals for your partnership’s affiliates, including the Aimco Operating Partnership, from time to time, in return for total fees of approximately $260,000 over the last two years. KTR has certified in its appraisal report that its compensation was not contingent upon the reporting of a predetermined value or direction in value that favors us, the amount of value estimate, the attainment of a stipulated result, or the occurrence of a subsequent event.

KTR performed a complete appraisal of Riverside Park Apartments. KTR has represented that its report was prepared in conformity with the Uniform Standards of Professional Appraisal Practice, the Code of Professional Ethics and the Standards of Professional Appraisal Practice of the Appraisal Institute and Title XI of the Financial Institutions Reform, Recovery and Enforcement Act of 1989, as amended. We furnished the appraiser with all of the necessary information requested by KTR in connection with the appraisal. The information furnished to the appraiser was true, correct and complete in all material respects. In preparing its valuation of Riverside Park Apartments, KTR’s analysis included, without limitation, an inspection of the premises, interviews with knowledgeable market participants, a review of historical income and expense statements, the current rent roll and other relevant financial and market information. The summary set forth below describes the material conclusions reached by KTR based on the values determined under the valuation approaches and subject to the assumptions and limitations

13

described below. KTR concluded that the market value of the fee simple estate of Riverside Park Apartments, as of October 24, 2005, is $122,300,000.

Summary of Valuation Approaches and Methodologies Employed.  The following summary describes the material approaches and analyses employed by KTR in preparing the appraisal. KTR relied principally on the income capitalization approach to valuation and secondarily on the sales comparison approach. Although the sales comparison approach is considered a reliable method for valuing property, the income capitalization approach is the primary approach used for valuing income-producing property, such as your partnership’s property.

The purpose of the income capitalization approach is to value a property by analyzing the anticipated future income and expenses of the property over an anticipated investment (or holding) period. This approach is widely applied in appraising income-producing properties. Under this approach, the value of a property is estimated by deducting an appropriate vacancy and collection allowance rate and all applicable expenses from the property’s anticipated gross annual income to arrive at a projected net operating income (“NOI”), which is then capitalized at an interest rate (the capitalization rate) commensurate with the risk inherent in the ownership of the property. The reliability of this approach is dependent on the reliability of the net income estimate and the capitalization rate. There are two primary income capitalization methods: (1) direct capitalization analysis, which converts a single year’s NOI into an indication of value and (2) discounted cash flow analysis, which estimates the value of a property by discounting to present value the forecasted net income of the property over the course of an anticipated investment period and the estimated proceeds from a hypothetical sale of such property at the end of such investment period. KTR utilized only the direct capitalization method.

The estimated value of a property derived using the sales comparison approach represents the probable price at which a property would be sold by a willing seller to a willing buyer at arms-length as of the date of value. The sales comparison approach analyzes recent sales of comparable improved properties in surrounding or competing areas to derive units of comparison that are then used to indicate a value for the subject property. Adjustments are made to the sales prices of comparable properties for differences from the subject property, such as terms of financing, date of sale, location and physical characteristics. Obtaining data with a high degree of comparability is most important for this method. The reliability of this method is dependent upon the availability of comparable sales data, the verification of such sales data, the degree of comparability, the extent of adjustment necessary for differences and the absence of non-typical conditions affecting the sales prices.

The cost approach method estimates the replacement or reproduction cost of the improvements on a property, less the estimated depreciation (physical, functional and economic), plus the estimated market value of the land, in order to arrive at a final indication of value for a property. This approach is based on the premise that an informed purchaser would not pay more for a property than the cost of constructing a building of similar utility and condition. The cost approach method is considered a reliable indicator of value for (a) new properties, (b) special use properties and (c) properties where the cost of reproducing the improvements is easily and accurately quantified, and there is no external or economic obsolescence. KTR noted the physical deterioration of Riverside Park Apartments due to age, normal wear and usage, and concluded that the cost approach would not be a reliable approach to value for the property due to the inherent inaccuracies and subjectivity involved in estimating the substantial degrees of physical deterioration.

Valuation Under Income Capitalization Approach.  Under the income capitalization approach, KTR performed a direct capitalization analysis to derive a value for Riverside Park Apartments, which involved (1) calculating potential gross annual income from the dwelling units; (2) estimating vacancy and credit loss to arrive at the property’s annual EGI; (3) estimating operating expenses to arrive at the stabilized NOI; (4) developing the overall capitalization rate; and (5) dividing NOI by the overall capitalization rate to arrive at a value for Riverside Park Apartments.

KTR performed a market rent analysis for the property to derive a projected annual rental income. The analysis included both a review of the subject’s current asking and actual rent rates as well as a comparison with comparable apartment properties. KTR calculated EGI by adding apartment rental collections to other income and then making adjustments, including adjustments based on an estimated stabilized physical vacancy of 6.0% and a 1.0% collection loss. Under this analysis, KTR arrived at an EGI of $14,691,643. Once the EGI was established, operating expenses were deducted from the EGI in order to arrive at an NOI of approximately $8,256,197. KTR performed a pro forma analysis of revenue and expenses for the property to derive the subject property’s stabilized NOI. KTR relied on the subject’s historical operating statements from 2002 through September 2005 for this estimate. KTR derived an overall capitalization rate of 6.75% based upon analysis of comparable sales, which ranged from approximately 6.5% to 7.0%, and the average rates for institutional and non-institutional grade properties

14

applied by institutional investors and advisors to real estate pension and portfolio funds when acquiring real estate, which ranged from approximately 6.3% to 7.5%. Using an overall capitalization rate of 6.75%, KTR determined that the direct capitalization method indicated a value of $122,300,000 (after rounding) for Riverside Park Apartments.

Valuation Under Sales Comparison Approach.  KTR compared Riverside Park Apartments with five multifamily apartment complexes with similar characteristics that were sold between December 2002 and July 2005 and located in Riverside Park’s real estate market area. The unit of comparison used was the sales price per unit, and all the comparable sales were analyzed on this basis. Although all of the comparables were of similar construction and were generally similar to Riverside Park with respect to age, condition and amenities, KTR made adjustments to the sales price per unit of each comparable property to reflect differences from Riverside Park in location, age and condition, number of units and average unit size. Based on the available data, KTR concluded a value range of $62,361 to $127,953 before adjustments. After adjustments, the sales prices per unit ranged from $81,069 to $106,445, with an average adjusted sales price of $97,042 per unit. Two of the comparables whose adjusted prices per unit were $102,362 and $102,969 were considered most similar to Riverside Park. Emphasizing these comparables, KTR considered a value indicator of $100,000 per unit to be appropriate. With 1,222 units at $100,000 per unit, KTR determined the market value of Riverside Park Apartments using the sales comparison approach to be $122,000,000 (after rounding). KTR assumed a marketing and exposure period of six to twelve months.

Reconciliation of Values and Conclusions of Appraisal.  The final step in the appraisal process was to reconcile the sales comparison approach and the income capitalization approach values to arrive at a final value conclusion. The reconciliation of the two approaches involved weighing the valuation techniques in relation to their substantiation by market and other sources of data, the relativity and applicability of the approaches to the property type, and the purpose of the valuation. KTR concluded a market value of $122,000,000 under the sales comparison approach and a market value of $122,300,000 under the income capitalization approach. After reconciling the various factors, KTR determined a final estimate of market value of $122,300,000 for Riverside Park Apartments as of October 24, 2005 in its appraisal report dated November 23, 2005.

Assumptions, Limitations and Qualifications of KTR’s Valuation.  In preparing the appraisal, KTR relied, without independent verification, on the accuracy and completeness of all information supplied or otherwise made available to it by or on behalf of the partnership. As of October 24, 2005, the date of KTR’s inspection, approximately 142 apartment units were in the process of being renovated and were not available for leasing. We instructed KTR to appraise Riverside Park Apartments without giving consideration to the renovation. KTR appraised the property on a stabilized basis and assumed that all 142 units that were under renovation were available for leasing and in similar condition to the property’s remaining units. Except as set forth herein, neither we, any of our affiliates nor the partnership imposed any conditions or limitations on the scope of KTR’s investigation or the methods and procedures to be followed in preparing the appraisal. KTR’s appraisal report and opinion of value were made subject to the following assumptions and limiting conditions:

•  the information and data contained in the appraisal report that were obtained from public record and other reliable sources were assumed to be satisfactory evidence upon which the final conclusion of value was based;

•  any sketches, plats, diagrams or previous surveys appearing in the report were only for the purpose of assisting the reader in visualizing the property;

•  all information known to us and relative to the valuation were assumed to be accurately furnished, and KTR assumed that there were no undisclosed leases, agreements, liens or other encumbrances affecting the use of the property;

•  ownership and management were assumed to be competent and in responsible hands;

•  KTR did not assume responsibility for the accuracy of any information identified as being furnished or prepared by others, and such information was assumed to be reliable;

•  it was assumed that there were no substances such as asbestos, urea-formaldehyde foam insulation, other chemicals, toxic wastes, or other potentially hazardous materials in existence or present on or in the property;

•  no consideration was given to the effect of state, local or federal income and gains taxes or of occupancy, hotel, capital levy, gift, estate, succession, inheritance or similar taxes which may be imposed upon any owner, lessee, or mortgagee by reason of any sale, conveyance, transfer, leasing, hypothetication, mortgage, pledge or other disposition of the property; and

15

•  KTR assumed the accuracy of the square footage and unit mix as indicated on the rent roll and marketing brochures that were provided to KTR.

Availability of Appraisal Report.  You may obtain a full copy of KTR’s appraisal upon request, without charge, by contacting the Information Agent at one of the addresses or the telephone number on the back cover of this Offer to Purchase. Copies of the appraisal for the property are also available for inspection and copying at the principal executive offices of the partnership during regular business hours by any interested unitholder or his or her designated representative at his or her cost. In addition, a copy of the appraisal has been filed with the SEC as an exhibit to the Tender Offer Statement and Rule 13e-3 Transaction Statement on Schedule TO and is available on the SEC’s site on the World Wide Web at http://www.sec.gov.

Fairness of the Offer

Factors in Favor of Fairness Determination.  The Aimco Entities (including the managing general partner on behalf of your partnership) believe the offer price and the structure of the transaction are fair to the unaffiliated limited partners. In support of such determination, the Aimco Entities considered the following factors and information:

•  the offer price is based on the Aimco Entities’ estimate of the net equity value of the units ($64,429);

•  each limited partner has an opportunity to make an individual decision on whether to tender his or her units (and how many to tender) or to continue to hold his or her units;

•  there is no established trading market for the limited partnership units, and the offer would provide immediate liquidity for tendering limited partners;

•  although our offer price reflects estimated prepayment penalties on mortgage debt, our offer price does not take into account other transaction costs that would ordinarily be incurred in connection with a sale of the property;

•  our offer price exceeds the most recent price at which the units sold in the secondary market ($56,000 through May 31, 2007);

•  our offer price exceeds the $44,440 per unit purchase price paid by the Aimco Operating Partnership in a negotiated purchase of 0.5 units in your limited partnership on March 11, 2005;

•  our offer price exceeds the book value per unit, which was ($35,840.99) at June 30, 2007;

•  our offer price is based on our estimate of gross property value for your partnership’s property ($140,000,000), which is higher than the gross property value determined by KTR in its 2005 appraisal ($122,300,000);

•  our offer price does not reflect any discount for minority interests; and

•  the partnership has not received any firm offers from third parties to purchase Riverside Park Apartments, or for any other extraordinary transaction during the past two years with which to compare the offer.

Factors Not in Favor of Fairness Determination.  In addition to the foregoing factors, the Aimco Entities considered the following countervailing factors:

•  our offer price does not ascribe any value to potential future improvements in the fair market value or operating performance of your partnership’s property, including any prospective increase in value or property income that may result from the redevelopment of Riverside Park Apartments; our offer price might be higher if it took into account any potential improvements in fair market value or property income;

•  in determining our offer price, we used the Aimco Entities’ estimate of the net equity value of the units, which may not represent the price you could obtain for your units in an open market;

•  our offer price is lower than the highest price at which the units have been sold in the secondary market ($67,523 in the year ended December 31, 2006);

•  our estimate of the net equity value of the units is based on our estimate of the gross property value of your partnership’s property ($140,000,000), which is lower than the value determined by Wright, an independent appraiser, in May 2006 ($149,000,000);

16

•  an unaffiliated representative was not retained to act solely on behalf of unaffiliated limited partners for purposes of negotiating the terms of the offer on an independent, arms length basis, which might have resulted in a higher offer price;

•  the general partner has substantial conflicts of interest with respect to our offer resulting from the fiduciary duties it owes to the Aimco Operating Partnership to avoid paying an excessive price for the limited partnership units, and the fiduciary duties it owes to the limited partners of the partnership, who have an interest in receiving the highest price possible for tendered units;

•  the terms of the offer were not approved by any independent directors; and

•  our offer does not require the approval or consent of any unaffiliated limited partners.

The Aimco Entities are of the opinion that the internal valuation of your partnership’s property, based on the direct capitalization method, is a reasonable approximation of the going concern value and liquidation value of the property. The Aimco Operating Partnership determined its offer price based on its estimate of the proceeds that would be available for distribution to limited partners in the event of a liquidation of the partnership’s property, as further described in the section “Special Factors — Valuation of Units,” and quantified the net equity value of all units, in the event of liquidation, to be $36,466,663.00. The Aimco Entities did not consider going concern value separately from liquidation value because they do not believe that there is a distinction between going concern value and liquidation value for an interest in a limited partnership in which the only asset is an apartment property such as Riverside Park Apartments. In calculating the offer price, a net equity value per unit was estimated based on the gross property value of Riverside Park Apartments. For income-producing properties such as your partnership’s property, the sale price in the event of liquidation is expected to be equal to the going concern value of the property, which is based on its operating income. In some markets, where there is a great demand for apartments to be converted into condominiums, it is possible that sale prices for apartment properties may be higher than their operating income would justify. In these situations, the liquidation value may exceed the going concern value. Your partnership’s property is not in a market where the demand for condominium conversions has resulted in this effect. Accordingly, the general partner did not consider the two values separately.

The 2006 appraisal conducted by Wright supported a value of $149,000,000 for Riverside Park Apartments based primarily on the income capitalization approach. We valued the property at $140,000,000. There are material differences between our valuation approach and Wright’s valuation approach, including the following:

•  the 2006 appraisal was conducted without regard for the redevelopment of Riverside Park Apartments and therefore used a stabilized vacancy number rather than an actual vacancy percentage while our valuation includes data for the 12 months ended June 30, 2007, and takes account of the current effects of the redevelopment, including actual vacancy loss. Actual vacancy loss (adjusted for the effects of construction accounting) is considerably higher than the estimated stabilized figure used in the 2006 appraisal;

•  the 2006 appraisal estimated a higher expense figure to account for the “as is” condition of the property, including both repairs and maintenance and capital replacements; and

•  the 2006 appraisal used a capitalization rate of 6.0% based upon analysis of comparable sales and a synthesis of mortgage interest and equity dividend rates, while we used the capitalization rate provided by PPR (4.92%), as of June 30, 2007, for the northern Virginia market.

Procedural Fairness.  Each of the Aimco Entities has interests in the offer or has relationships that present conflicts of interest in connection with the offer and considered these conflicts of interest along with the other factors enumerated above in making its fairness determination. See “Special Factors — Conflicts of Interest and Transactions with Affiliates.” In light of these conflicts of interest with respect to the offer, the Aimco Entities took into account the absence of the following procedural safeguards: (1) an unaffiliated representative to act solely on behalf of your partnership or the unaffiliated limited partners in negotiating the terms of this offer; (2) the approval of the offer by a majority of independent directors; and (3) the approval of the offer by a majority of the limited partners unaffiliated with the Aimco Entities. The Aimco Operating Partnership is a partnership managed by a general partner rather than a board of directors. The general partner is a corporation, the board of which is comprised entirely of affiliates of the Aimco Entities. As a result, there were no unaffiliated parties available to act as, or to hire, an unaffiliated representative for the unaffiliated limited partners. Furthermore, each limited partner has an opportunity to make an individual decision whether or not to tender, and there is no coercive aspect to the offer. For some limited

17

partners, liquidity may be very important, and the recognition of taxable income may not be a concern. For other limited partners, immediate liquidity may not be as desirable as deferring the recognition of taxable income.

The Aimco Entities do not believe any of the procedural safeguards were necessary with respect to determining that the offer price is fair because our offer price was determined in accordance with customary valuation methods. Despite the absence of these procedural safeguards, the Aimco Entities are of the opinion that the offer price is fair to the limited partners because:

•  our offer price is based on our internal valuation of the gross property value of your partnership’s property ($140,000,000);

•  our offer price is greater than the most recent price at which the units sold in the secondary market; and

•  this Offer to Purchase includes all information material to a limited partner’s decision whether or not to accept our offer.

Your general partner is our affiliate. We and your general partner are subsidiaries of Aimco. As a result, your general partner has a conflict of interest and makes no recommendation as to whether or not you should tender or refrain from tendering your units in this offer. While the general partner believes that the terms of our offer are fair, the general partner also believes that you must make your own decision whether or not to participate in this offer. The general partner is unable to make a recommendation because each limited partner’s circumstances may differ from those of other limited partners. These circumstances, which would impact the desirability of tendering units in the offer, include your financial position, your need or desire for liquidity, other financial opportunities available to you, and your tax position and the tax consequences to you of selling your units. You are encouraged to carefully review this 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 this offer.

None of the Aimco Entities (or any of their affiliates) have any plans or arrangements to tender any units. The general partner does not have any present plans or proposals which relate to or would result in an extraordinary transaction, such as a merger, reorganization or liquidation, involving your partnership; a purchase or sale or transfer of a material amount of your partnership’s assets; or any changes in your partnership’s present capitalization, indebtedness or distribution policies. The sale of your units pursuant to this offer will not be a taxable transaction to any of the Aimco Entities. Consequently, the Aimco Entities will not recognize gain or loss in connection with this offer. For information relating to certain relationships between your partnership and its general partner, on one hand, and Aimco and its affiliates, on the other, and conflicts of interests with respect to the tender offer, see “Special Factors — Conflicts of Interest and Transactions with Affiliates.”

Your partnership did not receive any report, opinion or appraisal with respect to the fairness of this offer or the offer price being offered to limited partners. However, the partnership did receive the appraisal prepared by KTR, as described above.

Conflicts of Interest and Transactions with Affiliates

Conflicts of Interest with Respect to the Offer.  The general partner of your partnership is an affiliate of Aimco. As a result, the general partner has substantial conflicts of interest with respect to the offer. We desire to purchase units at a low price and you desire to sell units at a high price. Such conflicts of interest in connection with the offer differ from those conflicts of interest that exist in connection with the general partner’s management of your partnership. Your general partner has filed a Solicitation / Recommendation Statement on Schedule 14D-9 with the SEC, which indicates that it is remaining neutral and making no recommendation as to whether limited partners should tender their units in the offer. YOU ARE URGED TO READ THIS OFFER TO PURCHASE AND THE SCHEDULE 14D-9 AND THE RELATED MATERIALS CAREFULLY AND IN THEIR ENTIRETY BEFORE DECIDING WHETHER TO TENDER YOUR UNITS.

Conflicts of Interest That Currently Exist for Your Partnership.  Conflicts of interest exist between the general partner of your partnership and its affiliates (including the other Aimco Entities), on the one hand, and you and the other limited partners of the partnership, on the other. The directors and officers of your general partner have fiduciary duties to manage the general partner in a manner beneficial to its stockholder, which is an affiliate of Aimco. At the same time, the general partner of your partnership has fiduciary duties to manage your partnership in a manner beneficial to all of the limited partners. Such conflicts of interest might arise in the following situations, among others:

•  The partnership pays fees and reimburses expenses to the general partner and its affiliates for costs incurred in managing and operating the partnership and its property. We and the general partner of your partnership received total fees and reimbursements (excluding property management fees) of approximately $646,000 in 2004, $951,000 in 2005 and

18

$2,522,000 in 2006. Total fees and reimbursements (excluding property management fees) for the six months ended June 30, 2007 were approximately $2,672,000. The property manager is entitled to receive four percent of gross receipts from the partnership’s property as compensation for providing property management services. The property manager received property management fees of approximately $568,000 in 2004, $530,000 in 2005 and $494,000 in 2006. Property management fees for the six months ended June 30, 2007 were approximately $227,000. We have no current intention of changing the fee structure for your general partner or the manager of your partnership’s property.

•  In determining to sell a property owned by your partnership, the general partner takes into consideration, among other factors: (i) Aimco’s objectives, including its liquidity needs and its relative desire to retain or dispose of properties within its entire portfolio, including the property owned by your partnership, and (ii) the investment objectives of your partnership. See “The Offer — Section 7. Certain Information Concerning Your Partnership — Investment Objectives and Policies; Sale or Financing of Investments.”

•  Decisions of the general partner with respect to the amount and timing of cash expenditures, borrowings, issuances of additional interests and reserves in any quarter will affect whether or the extent to which there is available cash to make distributions in a given quarter.

Competition Among Properties.  Because Aimco and your partnership both invest in apartment properties, these properties may compete with one another for tenants. Furthermore, you should bear in mind that Aimco may acquire properties in the general market area where your partnership’s property is located. We believe that this concentration of properties in a general market area will facilitate overall operations through collective advertising efforts and other operational efficiencies. In managing Aimco’s properties, we will attempt to reduce conflicts between competing properties by referring prospective customers to the property considered to be most conveniently located for the customer’s needs.

Future Offers.  We are not obligated to make another tender offer for units in your partnership. We have no current plans to conduct future tender offers for the units in your partnership, but our plans may change based on future circumstances, including tender offers made by third parties. Any such future offers that we make could be at prices that are more or less than the current offer price.

Transactions with Affiliates.  Your partnership has no employees and is dependent on Aimco/Bethesda and us for the management and administration of all partnership activities. The partnership agreement provides for (i) certain payments to our affiliates for services, (ii) reimbursement of certain expenses incurred by our affiliates on behalf of the partnership and (iii) an annual partnership and investor service fee of $110,000 subject to a 6% annual increase.

We and the general partner of your partnership, which is our affiliate, are entitled to receive 4% of gross receipts from your partnership’s property as compensation for providing property management services, and received property management fees of approximately $568,000 in 2004, $530,000 in 2005 and $494,000 in 2006. Property management fees for the six months ended June 2007 were approximately $227,000. We were eligible to receive reimbursement of accountable administrative expenses amounting to approximately $489,000 in 2004, $595,000 in 2005, $1,157,000 in 2006, and 1,287,000 in the six months ended June 30, 2006. These amounts include the annual partnership and investor service fee discussed above of approximately $279,000 in 2004, $296,000 in 2005 and $314,000 in 2006. We expect the annual partnership and investor service fee to be approximately $333,000 in 2007. Also included in these amounts are fees related to construction management services for certain capital improvement expenditures (not related to the redevelopment project) provided by an affiliate of the general partner of approximately $36,000 in 2004, $10,000 in 2005, $78,000 in 2006, and $42,000 in the six months ended June 30, 2007. The construction management service fees are calculated based on a percentage of current additions to investment property. In connection with the redevelopment project, an affiliate of the general partner received a redevelopment supervision fee of $124,000 for the year ended December 31, 2005, $570,000 for the year ended December 31, 2006, and $960,000 for the six months ended June 30, 2007, calculated as 6% of the actual redevelopment costs. The total redevelopment supervision fee is estimated to be approximately $6,900,000 based on current estimated redevelopment costs.

In accordance with the partnership agreement, an affiliate of the general partner loaned the partnership approximately $287,000 in 2004, $850,000 in 2005 and $5,641,000 in 2006 to cover capital improvements (including the redevelopment of Riverside Park Apartments), property taxes and operating expenses. During the six months ended June 30, 2007, an affiliate of the general partner advanced the partnership approximately $1,024,000 to fund the redevelopment and operating expenses at Riverside Park Apartments. Interest accrues at the prime rate plus 2% (10.25% at June 30, 2007). During the year ended December 31, 2006, the partnership repaid the outstanding advances and accrued interest of approximately $7,042,000 from

19

proceeds from the additional financing obtained on Riverside Park Apartments. Interest expense amounted to less than $1,000 in 2004, approximately $61,000 in 2005 and approximately $203,000 in 2006. Interest expense amounted to approximately $1,000 for the six months ended June 30, 2007. At June 30, 2007, the amount of the outstanding advances and accrued interest was approximately $1,025,000. Subsequent to June 30, 2007, an affiliate of the general partner advanced the partnership approximately $3,573,000 to fund the redevelopment and operating expenses at Riverside Park Apartments.

In connection with the additional financing obtained on your partnership’s property, the partnership paid an affiliate of the general partner approximately $300,000 in 2006 for services provided.

The partnership insures its property up to certain limits through coverage provided by Aimco, which is generally self-insured for a portion of losses and liabilities related to workers’ compensation, property casualty, general liability and vehicle liability. The partnership insures its property above the Aimco limits through insurance policies obtained by Aimco from insurers unaffiliated with your general partner. The partnership was charged by Aimco and its affiliates approximately $156,000, $171,000, and $292,000 during the years ended December 31, 2004, 2005 and 2006, respectively, for insurance coverage and fees associated with policy claims administration. During the six months ended June 30, 2007, the partnership was charged by Aimco and its affiliates approximately $424,000 for hazard insurance coverage and fees associated with policy claims administration. Additional charges will be incurred by the partnership during 2007 as other insurance policies renew later in the year.

Future Plans and Proposals

As described above under “Special Factors — Purpose, Alternatives and Reasons for the Offer,” your general partner is our affiliate and, therefore we have the ability to control the management of your partnership. In addition, we are affiliated with the manager of your partnership’s property. We currently intend that, upon consummation of the offer, we will hold the units acquired and your partnership will continue its business and operations substantially as they are currently being conducted. The offer is not expected to have any effect on partnership operations.

Although we are not obligated to do so, we may make future tender offers. However, we have no current plans to conduct future tender offers for units in your partnership. We may acquire additional units or sell units after completion or termination of the offer. Any acquisition may be made through private purchases, through one or more future tender or exchange offers or by any other means deemed advisable. Any acquisition may be at a price higher or lower than the price to be paid for the units purchased pursuant to this offer, and may be for cash, limited partnership interests in the Aimco Operating Partnership or other consideration. We may consider selling some or all of the units we acquire pursuant to this offer to persons not yet determined, which may include our affiliates. We may also attempt to buy your partnership’s property or attempt to acquire additional units through merger or other consolidation, although we have no present intention to do so. There can be no assurance, however, that we will initiate or complete, or will cause your partnership to initiate or complete, any subsequent transaction during any specific time period following the expiration of the offer or at all.

Upon consummation of this offer, your partnership will terminate the registration of its limited partnership units under the Exchange Act and will no longer file reports with the SEC. As a result, it may become more difficult for you to obtain information about your partnership, its results of operations and financial condition. See “Special Factors — Effects of the Offer.”

In March 2005, the partnership began a major redevelopment project at Riverside Park Apartments intended to help it compete with other properties in its local market. The redevelopment is expected to consist of renovation and appliance upgrades to each apartment unit and the addition of a new clubhouse and fitness center. The general partner estimates that project costs will be approximately $142,000,000. Based on current redevelopment plans, the general partner expects the redevelopment to be completed in April 2011. During the construction period, certain expenses are being capitalized and depreciated over the remaining life of the property. The partnership expects to fund the redevelopment from operations, advances from us and third party debt. At the present time, there can be no assurance that the redevelopment will proceed as currently planned or that the redevelopment as currently planned will be successfully completed in the anticipated timeframe. Many factors could cause the redevelopment to be delayed or to cost the partnership more than currently anticipated. Such factors include local economic conditions, interest rates, shortages of materials or skilled labor, labor disputes, unforeseen environmental or engineering problems, work stoppages, scheduling problems, weather interference or natural disasters.

20

Based on the general partner’s current estimates, if the redevelopment project is completed in the timeframe and at the cost to the partnership that the general partner anticipates, the redevelopment would result in an increase in annual reportable net operating income from approximately $8.8 million for the year ended December 31, 2006 to approximately $17.3 million following completion of the redevelopment. The general partner also estimates that completion of the redevelopment, in the anticipated timeframe and at the projected cost, would result in an increase in average annual rental rates of approximately 69%. During the course of the redevelopment, however, we will be unable to rent units as they come under construction. The general partner anticipates lost revenue of approximately $14.3 million as a result of the loss of estimated rents. These projections are estimates only, and are subject to the risks set forth above, as well as other risks that the general partner may not currently anticipate and that may be beyond its or the partnership’s control, such as changes in market rental rates or other market conditions, including the general economic climate in the local market and the competition for tenants in such market.

Additional expenditures for improvements may be incurred only if cash is available from operations, partnership reserves or advances from the general partner’s affiliates. Due to the extent of the redevelopment project planned at the property for the next several years, it is not expected that the partnership will have any distributable cash flow during the redevelopment period.

Except as set forth herein, neither we nor the general partner have any other present plans or proposals which relate to or would result in any extraordinary transaction, such as a merger, reorganization or liquidation, involving your partnership; any purchase or sale or transfer of a material amount of your partnership’s assets; any change in composition of your partnership’s senior management or personnel or their compensation; any material change in your partnership’s present capitalization, indebtedness or distribution policy; or any other material change in your partnership’s organizational structure or business. However, we expect that, consistent with your general partner’s fiduciary obligations, the general partner will seek and review opportunities, including opportunities identified by us, to engage in transactions which could benefit your partnership, such as sales or refinancings of assets or a combination of the partnership with one or more other entities, with the objective of seeking to maximize returns to limited partners. As discussed under “The Offer — Section 7. Certain Information Concerning Your Partnership — Investment Objectives and Policies; Sale or Financing of Investments,” the general partner regularly evaluates the real estate and capital markets. The general partner may consider refinancing the partnership’s existing indebtedness to the extent that the general partner is able to obtain a lower interest rate or if such indebtedness is approaching maturity. Furthermore, in the event that the general partner receives an attractive offer for your partnership’s property, the general partner would give due consideration to such an offer.

If any of the transactions referred to above occur and financial benefits accrue to the limited partners, we will participate in those benefits to the extent of our ownership of units. The agreement of limited partnership prohibits limited partners from voting on actions taken by the partnership, unless otherwise specifically permitted therein. Limited partners may vote on a liquidation, and we will be able to control the outcome of any such vote. Our primary objective in seeking to acquire the units pursuant to the offer is not, however, to influence the vote on any particular transaction, but rather to generate a profit on the investment represented by those units.

RISK FACTORS

Before deciding whether or not to tender any of your units, you should consider carefully the following risks and disadvantages of the offer:

There will be a reduction of available information about your partnership as a result of this offer.

Upon consummation of this offer, your partnership will terminate the registration of its limited partnership units under the Exchange Act and will no longer file reports with the SEC, such as annual reports on Form 10-KSB containing annual audited financial statements and quarterly reports on Form 10-QSB containing unaudited quarterly financial statements. In addition, it will no longer be subject to certain provisions of the Sarbanes-Oxley Act of 2002 and the liability provisions of the Exchange Act. The lack of such filings could adversely affect the already limited secondary market which currently exists for units in your partnership and may discourage future offers to purchase your units. In such a case, you would regularly have access only to the information your partnership’s agreement of limited partnership requires your general partner (which is our affiliate) to provide each year, which consists primarily of tax information. See “Special Factors — Effects of the Offer — Expected Detriments of the Offer to Unaffiliated Limited Partners — Termination of SEC Registration” and “Special Factors — Future Plans and Proposals.”

Our offer price is based on our internal valuation of the gross property value of your partnership’s property. However, a 2006 appraisal indicates a higher property value and, accordingly, a higher value per unit.

Our offer price is based on our estimate of the net equity value per unit, which is equal to the amount that would be distributed to limited partners in the event of a hypothetical winding up of the partnership, assuming that the partnership’s property is sold at a price equal to our estimate of its gross property value. Our starting point in this process is our estimate of the gross property value for Riverside Park Apartments. The gross property value is directly comparable to the gross sale price if the property were sold. In determining gross property value, we started with the property income for your partnership from the 12 month period ended June 30, 2007 and made certain adjustments for capital expenditures. We then divided net property income by a capitalization rate of 4.92% to derive an estimated gross property value of $139,600,000, which we rounded up to $140,000,000. For a more detailed description of our valuation process and the independent appraisal, see “Special Factors — Valuation of Units.”

In 2006, in connection with refinancings of mortgages encumbering your partnership’s properties, the lender obtained an appraisal of Riverside Park Apartments which indicated an appraised value that is higher than our estimated gross property value. The lender appraisal is dated May 25, 2006, and indicates an appraised value of $149,000,000 for the Riverside Park Apartments compared to our estimate of $140,000,000. If our offer price had been based on this appraisal instead of our estimate of gross property value, our offer price per unit would be slightly higher.

Our offer price may not represent the price you could obtain for your units in an open market.

There is no established or regular trading market for your units, nor is there another reliable standard for determining the fair market value of the units. Our offer price does not necessarily reflect the price that you would receive in an open market for your units. Such prices could be higher than our offer price. See “Special Factors — Valuation of Units.”

Our offer price does not reflect future prospects.

Our offer price does not ascribe any value to potential future improvements in the fair market value or operating performance of your partnership’s property, including any prospective increase in value or property income that may result from the redevelopment of Riverside Park Apartments. In March 2005, the Partnership began a major redevelopment project at Riverside Park Apartments intended to make the property more competitive with other properties in its local market. The redevelopment is expected to consist of renovation and appliance upgrades to each apartment unit and the addition of a new clubhouse and fitness center. Based on current plans, the general partner expects the redevelopment to be complete in April 2011. Your general partner believes that the redevelopment, if completed, of Riverside Park Apartments will increase the net operating income at the property and will permit it to remain competitive with other rental properties in the local market. Based on current estimates, if the redevelopment project is completed in the anticipated timeframe and at the projected cost, the general partner estimates that the redevelopment would result in an increase in annual reportable net operating income from approximately $8.8 million for the year ended December 31, 2006 to approximately $17.3 million following completion of the

22

redevelopment. The general partner also estimates that completion of the redevelopment would result in an increase in average annual rental rates of approximately 69%. During the course of the redevelopment, however, we will be unable to rent units as they come under construction. The general partner anticipates lost revenue of approximately $14.3 million as a result of the loss of estimated rents. Our offer price might be higher if it took into account the redevelopment or any potential improvements in the fair market value or property income. For more information regarding the redevelopment, see “Special Factors — Future Plans and Proposals” and “The Offer — Section 7. Certain Information Concerning Your Partnership — Investment Objectives and Policies; Sale or Financing of Investments.”

Our offer price was determined without any arms-length negotiations, which might result in a higher value for your partnership units.

Our offer price was determined without any arms-length negotiations. If your partnership were to sell its assets and liquidate, the value of the assets would be determined through negotiations with third parties, who may be willing to pay more for your partnership’s property than the value implied by our offer price. Although the actual proceeds you might receive in a liquidation are uncertain, they could exceed our offer price. Similarly, other persons might ascribe a value to your partnership units that is higher than our offer price. As a result, you might be able to sell your units to a third party at a price that exceeds our offer price.

Our offer price for your units may be less than the liquidation value attributable to your units.

The actual proceeds obtained from liquidation are highly uncertain and could be more than our estimate. Other persons could derive different estimates of the liquidation value. If your partnership were to sell its assets and liquidate, the value of the assets would be determined through negotiations with third parties, who may use different valuation methods to determine the value of your partnership’s assets. Accordingly, our offer price could be less than the net proceeds that you would realize upon an actual liquidation of your partnership. In addition, your partnership would generally make liquidating distributions in accordance with the partners’ respective positive capital account balances, regardless of whether such distributions are proportionate to the percentage of partnership units held by a limited partner. Our offer price is based upon an estimated average per-unit value and not upon your capital account balance. Accordingly, the amount that you receive pursuant to our offer may be less than the amount you would have received in a liquidating distribution of the partnership.

Continuation of the partnership; no time frame regarding sale of property.

Your general partner, which is our affiliate, is proposing to continue to operate your partnership and not to attempt to liquidate it at the present time. It is not known when the property owned by your partnership may be sold. The general partner of your partnership believes the redevelopment of Riverside Park Apartments will result in increases in future rental income from the property, and appreciation in property value. As a result, the general partner has no current intention of pursuing a sale of the property.

Holding your units may result in greater future value.

Although a liquidation of your partnership is not currently contemplated in the near future, you might receive more value if you retain your units until your partnership is liquidated. Your general partner believes that the redevelopment of Riverside Park Apartments, if completed, will increase the net operating income at the property and will permit it to remain competitive with other rental properties in the local market. However, our offer price does not ascribe any value to the redevelopment, and if the operating performance of the property improves as currently anticipated, you could receive more value for your units in the future. For more information regarding the redevelopment, see “Special Factors — Future Plans and Proposals” and “The Offer — Section 7. Certain Information Concerning Your Partnership — Investment Objectives and Policies; Sale or Financing of Investments.” In addition, at the current time, the general partner of your partnership believes that selling your partnership’s property would not be advantageous given market conditions, the condition of the property and tax considerations. If your partnership’s property were sold in the future and the net proceeds from the sale were distributed to the limited partners, the per-unit amount of such distributions might exceed our current offer price. For partnerships in which we control the general partner and have made tender offers, it has not been unusual for those partnerships to subsequently sell a property at a price in excess of the value we used to determine our tender offer price.

23

Your partnership has a significant balloon payment due on its mortgage debt.

Your partnership has a balloon payment of approximately $70,738,000 due on its mortgage in July 2020. Your partnership will have to refinance such debt, sell assets or otherwise obtain additional funds prior to the balloon payment date, or it will be in default and could lose its property to foreclosure.

The general partner faces conflicts of interest with respect to this offer.

The general partner of your partnership is our affiliate and, therefore, has substantial conflicts of interest with respect to our offer. The directors and officers of your general partner have fiduciary duties to its sole member, which is an affiliate of Aimco. At the same time, the general partner of your partnership has fiduciary duties to all of the limited partners. The duties of the general partner to the partnership and its limited partners may come into conflict with the duties of the directors and officers of the general partner to the Aimco Operating Partnership, as sole member of the general partner. Because we are making this offer with a view to making a profit, there is a conflict between our desire to purchase your units at a low price and your desire to sell your units at a high price. Consequently, there is a risk that our estimate of the value of the units (and our offer price) is lower than the value that would be determined by an independent third party.

Your general partner is not making a recommendation regarding this offer.

The general partner of your partnership (which is our affiliate) makes no recommendation as to whether or not you should tender or refrain from tendering your units because each limited partner’s circumstances may differ from those of other limited partners. Although the general partner believes the offer is fair, you must make your own decision whether or not to participate in the offer based upon a number of factors, including several factors that may be personal to you such as your financial position, your need or desire for liquidity, other financial opportunities available to you, your tax position and the tax consequences to you of selling your units. You are encouraged to carefully review this 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 this offer.

Your general partner faces conflicts of interest relating to management fees.

Because we or our subsidiaries receive fees for managing your partnership and its property, a conflict of interest exists between continuing the partnership and receiving such fees, and liquidating the partnership and terminating such fees. We and the general partner of your partnership received total fees (excluding property management fees) of approximately $2,672,000 during the six months ended June 30, 2007. The property manager, which is our affiliate, is entitled to receive three percent of residential rent collections and five percent of commercial income from the partnership’s property as compensation for providing property management services. It received property management fees of approximately $227,000 during the six months ended June 30, 2007.

If we do not acquire all of the outstanding units in this offer, we may make a future offer at a higher price.

It is possible that we may conduct a future offer at a higher price, although we have no obligation or current intention to do so. Our decision to conduct a future offer will depend on, among other things, the performance of the partnership, prevailing economic conditions and our interest in acquiring additional units.

Your U.S. federal tax liability resulting from a sale of your units could exceed our offer price.

For U.S. federal income tax purposes, your sale of units for cash will be a taxable sale, with the result that you will recognize taxable gain or loss measured by the difference between the amount realized on the sale and your adjusted tax basis in the units of limited partnership interest of your partnership that you transfer to us. The “amount realized” with respect to a unit of limited partnership interest that you transfer to us will be equal to the sum of the amount of cash received by you for the unit sold pursuant to the offer plus the amount of partnership liabilities allocable to your unit. Depending on your basis in the units and your tax position, your tax liability resulting from a sale of units to us pursuant to the offer could exceed our offer price. The particular tax consequences for you of our offer will depend upon a number of factors related to your tax situation, including your adjusted tax basis in the units you transfer to us, whether you dispose of all of your units and whether you have available suspended passive losses, credits or other tax items to offset any gain recognized as a result of your sale of your units. We may also be required by federal, state or local tax laws to withhold a portion of our offer price. Because the income tax consequences

24

of tendering units will not be the same for everyone, you should consult your tax advisor to determine the tax consequences of the offer to you.

If you tender your units in this offer, you will no longer be entitled to distributions from your partnership.

If you tender your units in response to our offer, you will transfer to us all right, title and interest in and to all of the units we accept and the right to receive all distributions in respect of such units on and after the date on which we accept such units for purchase. Accordingly, for any units that we acquire from you, you will not receive any future distributions from operating cash flow of your partnership or upon a sale or refinancing of the property owned by your partnership.

You could recognize gain in the event of a future reduction in your partnership’s liabilities.

Generally, a decrease in your share of partnership liabilities is treated, for federal income tax purposes, as a deemed cash distribution. Although the general partner of your partnership does not have any current plan or intention to reduce the liabilities of your partnership, it is possible that future economic, market, legal, tax or other considerations may cause the general partner to reduce your share of the partnership liabilities. If you retain all or a portion of your units and your share of the partnership liabilities were to be reduced, you would be treated as receiving a hypothetical distribution of cash resulting from a decrease in your share of the liabilities of the partnership. Any such hypothetical distribution of cash would be treated as a nontaxable return of capital to the extent of your adjusted tax basis in your units and thereafter as gain. Gain recognized by you on the disposition of retained units with a holding period of 12 months or less may be classified as short-term capital gain and subject to taxation at ordinary income tax rates.

We could delay acceptance of, and payment for, your units.

We reserve the right to extend the period of time during which our offer is open and thereby delay acceptance for payment of any tendered units. The offer may be extended in our reasonable discretion, and no payment will be made in respect of tendered units until the expiration of the offer and acceptance of units for payment. We will pay for or return tendered units promptly after expiration of the offer.

THE OFFER

1.   Terms of the Offer; Expiration Date

Upon the terms and subject to the conditions of the offer, we will accept (and thereby purchase) any and all units that are validly tendered on or prior to the expiration date and not withdrawn in accordance with the procedures set forth in “The Offer — Section 4. Withdrawal Rights.” For purposes of the offer, the term “expiration date” shall mean midnight, New York City time, on October 29, 2007, unless we in our reasonable discretion shall have extended the period of time for which the offer is open. See “The Offer — Section 5. Extension of Tender Offer Period; Termination; Amendment; No Subsequent Offering Period,” for a description of our right to extend the period of time during which the offer is open and to amend or terminate the offer.

The purchase price per unit will automatically be reduced by the aggregate amount of distributions per unit, if any, made or declared by your partnership on or after the commencement of our offer and prior to the date on which we acquire your units pursuant to our offer. If the offer price is reduced in this manner, we will notify you and, if necessary, we will extend the offer period so that you will have at least ten business days from the date of our notice to withdraw your units.

If, prior to the expiration date, we increase the consideration offered pursuant to the offer, the increased consideration will be paid for all units accepted for payment pursuant to the offer, whether or not the units were tendered prior to the increase in consideration.

The offer is conditioned on satisfaction of certain conditions. The offer is not conditioned upon any minimum number of units being tendered. See “The Offer — Section 11. Conditions to the Offer,” which sets forth in full the conditions to the offer. We reserve the right (but in no event shall we be obligated), in our reasonable discretion, to waive any or all of those conditions. If, on or prior to the expiration date, any or all of the conditions have not been satisfied or waived, we reserve the right to (i) decline to purchase any of the units tendered, terminate the offer and return all tendered units to tendering limited partners, (ii) waive all the unsatisfied conditions and purchase, subject to the terms of the offer, any and all units validly

25

tendered, (iii) extend the offer and, subject to your withdrawal rights, retain the units that have been tendered during the period or periods for which the offer is extended, or (iv) amend the offer. Although we intend to pay for tendered units that have been accepted for payment as promptly as practicable, which we expect will be within three business days after expiration of the offer, by executing the letter of transmittal, you will agree that the transfer of units will be deemed to take effect as of the first day of the calendar quarter in which the offer expires. Although the payment date will occur after expiration of the offer, in the books and records of the partnership the change in ownership of tendered units will be made retroactive to the first day of the calendar quarter in which the offer expires. For tax, accounting and financial reporting purposes, the transfer of tendered units will be deemed to take effect on the first day of the calendar quarter in which the offer expires. Accordingly, all profits and losses relating to any tendered units will be allocated to us from and after this date. If we waive any material conditions to our offer, we will notify you and, if necessary, we will extend the offer period so that you will have at least five business days from the date of our notice to withdraw your units.

The offer to purchase is being mailed on or about October 1, 2007 to the persons shown by your partnership’s records to have been limited partners or, in the case of units owned of record by Individual Retirement Accounts and qualified plans, beneficial owners of units.

2.   Acceptance for Payment and Payment for Units

Upon the terms and subject to the conditions of the offer, we will purchase, by accepting for payment, and will pay for, any and all units validly tendered as promptly as practicable, which we expect will be within three business days after expiration of the offer. A tendering beneficial owner of units whose units are owned of record by an Individual Retirement Account or other qualified plan will not receive direct payment of the offer price; rather, payment will be made to the custodian of such account or plan. In all cases, payment for units purchased pursuant to the offer will be made only after timely receipt by the Information Agent of a properly completed and duly executed letter of transmittal and other documents required by the letter of transmittal. See “The Offer — Section 3. Procedure for Tendering Units.” UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER PRICE BY REASON OF ANY DELAY IN MAKING SUCH PAYMENT.

For purposes of the offer, we will be deemed to have accepted for payment pursuant to the offer, and thereby purchased, validly tendered units, if, as and when we give verbal or written notice to the Information Agent of our acceptance of those units for payment pursuant to the offer. Payment for units accepted for payment pursuant to the offer will be made through the Information Agent, which will act as agent for tendering limited partners for the purpose of receiving cash payments from us and transmitting cash payments to tendering limited partners.

If any tendered units are not accepted for payment by us for any reason, the letter of transmittal with respect to such units not purchased may be destroyed by the Information Agent or us or returned to you. You may withdraw tendered units until the expiration date (including any extensions). In addition, if we have not accepted units for payment by November 29, 2007, you may then withdraw any tendered units. After the expiration date, the Information Agent may, on our behalf, retain tendered units, and those units may not be otherwise withdrawn if, for any reason, acceptance for payment of, or payment for, any units tendered pursuant to the offer is delayed or we are unable to accept for payment, purchase or pay for units tendered pursuant to the offer. Any such action is subject, however, to our obligation under Rule 14e-1(c) under the Exchange Act, to pay you the offer price in respect of units tendered or return those units promptly after termination or withdrawal of the offer.

We reserve the right to transfer or assign, in whole or in part, to one or more of our affiliates, the right to purchase units tendered pursuant to the offer, but no such transfer or assignment will relieve us of our obligations under the offer or prejudice your rights to receive payment for units validly tendered and accepted for payment pursuant to the offer.

3.   Procedure for Tendering Units

Valid Tender.  To validly tender units pursuant to the offer, a properly completed and duly executed letter of transmittal, and any other required documents must be received by the Information Agent, at one of its addresses set forth on the back cover of this Offer to Purchase, on or prior to the expiration date. You may tender all or any portion of your units. No alternative, conditional or contingent tenders will be accepted.

Signature Requirements.  If the letter of transmittal is signed by the registered holder of a unit and payment is to be made directly to that holder, then no signature guarantee is required on the letter of transmittal. Similarly, if a unit is tendered for the account of a member firm of a registered national securities exchange, a member of the National Association of Securities

26

Dealers, Inc. or a commercial bank, savings bank, credit union, savings and loan association or trust company having an office, branch or agency in the United States (each an “Eligible Institution”), no signature guarantee is required on the letter of transmittal. However, in all other cases, all signatures on the letter of transmittal must be guaranteed by an Eligible Institution.

In order for you to tender in the offer, your units must be validly tendered and not withdrawn on or prior to the expiration date.

The method of delivery of the letter of transmittal and all other required documents is at your option and risk, and delivery will be deemed made only when actually received by the Information Agent. If delivery is by mail, registered mail with return receipt requested is recommended. In all cases, sufficient time should be allowed to assure timely delivery.

Appointment as Proxy; Power of Attorney.  By executing the letter of transmittal, you are irrevocably appointing us and our designees as your proxy, in the manner set forth in the letter of transmittal and each with full power of substitution, to the fullest extent of your rights with respect to the units tendered by you and accepted for payment by us. Each such proxy shall be considered coupled with an interest in the tendered units. Such appointment will be effective when, and only to the extent that, we accept the tendered units for payment. Upon such acceptance for payment, all prior proxies given by you with respect to the units will, without further action, be revoked, and no subsequent proxies may be given (and if given will not be effective). We and our designees will, as to those units, be empowered to exercise all voting and other rights as a limited partner as we, in our sole discretion, may deem proper at any meeting of limited partners, by written consent or otherwise. By executing the letter of transmittal, you agree to execute all such documents and take such other actions as shall be reasonably required to enable the units tendered to be voted in accordance with our directions. The proxy granted by you to us will remain effective and be irrevocable for a period of ten years following the termination of our offer.

By executing the letter of transmittal, you also irrevocably constitute and appoint us and our designees as your attorneys-in-fact, each with full power of substitution, to the fullest extent of your rights with respect to the units tendered by you and accepted for payment by us. Such appointment will be effective when, and only to the extent that, we pay for your units and will remain effective and be irrevocable for a period of ten years following the termination of our offer. You will agree not to exercise any rights pertaining to the tendered units without our prior consent. Upon such payment, all prior powers of attorney granted by you with respect to such units will, without further action, be revoked, and no subsequent powers of attorney may be granted (and if granted will not be effective). Pursuant to such appointment as attorneys-in-fact, we and our designees each will have the power, among other things, (i) to transfer ownership of such units on the partnership books maintained by your general partner (and execute and deliver any accompanying evidences of transfer and authenticity it may deem necessary or appropriate in connection therewith), (ii) upon receipt by the Information Agent of the offer consideration, to become a substituted limited partner, to receive any and all distributions made by your partnership on or after the date on which we acquire such units, and to receive all benefits and otherwise exercise all rights of beneficial ownership of such units in accordance with the terms of our offer, (iii) to execute and deliver to the general partner of your partnership a change of address form instructing the general partner to send any and all future distributions to which we are entitled pursuant to the terms of the offer in respect of tendered units to the address specified in such form, and (iv) to endorse any check payable to you or upon your order representing a distribution to which we are entitled pursuant to the terms of our offer, in each case, in your name and on your behalf.

Assignment of Interest in Future Distributions.  By executing the letter of transmittal, you will irrevocably assign to us and our assigns all of your right, title and interest in and to any and all distributions made by your partnership from any source and of any nature, including, without limitation, distributions in the ordinary course, distributions from sales of assets, distributions upon liquidation, winding-up or dissolution, payments in settlement of existing or future litigation, and all other distributions and payments from and after the expiration date of our offer, in respect of the units tendered by you and accepted for payment and thereby purchased by us. If, after the unit is accepted for payment and purchased by us, you receive any distribution from any source and of any nature, including, without limitation, distributions in the ordinary course, distributions from sales of assets, distributions upon liquidation, winding-up or dissolution, payments in settlement of existing or future litigation and all other distributions and payments, from your partnership in respect of such unit, you will agree to forward promptly such distribution to us.

Release of Claims.  By executing the letter of transmittal, effective upon acceptance for payment of the units tendered by you, you will, on behalf of yourself, your heirs, estate, executor, administrator, successors and assigns, and your partnership, fully, finally and forever release, relinquish and discharge us and our predecessors, successors and assigns and our present and former parents, subsidiaries, affiliates, investors, insurers, reinsurers, officers, directors, employees, agents, administrators, auditors, attorneys, accountants, information and solicitation agents, investment bankers, and other representatives, including

27

but not limited to the Aimco Operating 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, 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) the ownership of one or more units in your partnership, including but not limited to, any and all claims related to the management of your partnership or the property owned by your partnership (whether currently or previously), the payment of management fees or other monies to the general partner of your partnership and its affiliates, prior acquisitions or tender offers, or (b) the purchase, acquisition, holding, sale, tender or voting of one or more units in your partnership (collectively, the “Released Claims”); provided, however, that the Released Claims are not intended to include any claim based upon violations of federal or state securities laws in connection with this offer.

In addition, you will expressly waive and relinquish, to the fullest extent permitted by law and consistent with the releases described 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.

You will have also waived 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. You may hereafter discover facts in addition to or different from those which you now know or believe to be true with respect to the subject matter of the Released Claims, but you will 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.

You will acknowledge and agree that the releases contained in the letter of transmittal are intended to include the Released Claims, which you may have and which you do not know or suspect to exist in your favor against the Releasees and that the releases contained in the letter of transmittal extinguish those claims. You will represent and warrant to the Releasees that you have been advised by your attorney of the effect and import of the provisions of Section 1542, and that you have not assigned or otherwise transferred or subrogated any interest in the Released Claims.

Determination of Validity; Rejection of Units; Waiver of Defects; No Obligation to Give Notice of Defects.  All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of units pursuant to our offer will be determined by us, in our reasonable discretion. We reserve the absolute right to reject any or all tenders of any particular unit determined by us not to be in proper form or if the acceptance of or payment for that unit may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive or amend any of the conditions to the offer that we are legally permitted to waive as to the tender of any particular unit and to waive any defect or irregularity in any tender with respect to any particular unit of any particular limited partner. If we waive any of the conditions of the offer with respect to the tender of a particular unit or with respect to a particular limited partner, we will waive such condition with respect to all other tenders of units or all other limited partners in this offer as well. We reserved the right to interpret the terms and conditions of the offer (including the letter of transmittal) in a reasonable manner. No tender of units will be deemed to have been validly made unless and until all defects and irregularities have been cured or waived. Neither we, the Information Agent, nor any other person will be under any duty to give notification of any defects or irregularities in the tender of any unit or will incur any liability for failure to give any such notification.

Backup Federal Income Tax Withholding.  To prevent the possible application of back-up federal income tax withholding with respect to payment of the offer price, you must provide us with your correct taxpayer identification number. See the instructions to the letter of transmittal and “Special Factors — Material Federal Income Tax Matters.”

State and Local Withholding.  If you tender any units pursuant to this offer, we may be required under state or local tax laws to deduct and withhold a portion of our offer price. You should consult your tax advisor concerning whether any state or

28

local withholding would be required on a disposition of your units and whether such amounts may be available to you as a credit on your state or local tax returns.

FIRPTA Withholding.  To prevent the withholding of federal income tax in an amount equal to 10% of the amount realized on the disposition (the amount realized is generally the offer price plus the partnership liabilities allocable to each unit purchased), you must certify that you are not a foreign person if you tender units. See the instructions to the letter of transmittal and “Special Factors — Material Federal Income Tax Matters.”

Transfer Taxes.  The amount of any transfer taxes (whether imposed on the registered holder of units or any person) payable on account of the transfer of units will be deducted from the purchase price unless satisfactory evidence of the payment of such taxes or exemption therefrom is submitted.

Binding Agreement.  A tender of a unit pursuant to any of the procedures described above and the acceptance for payment of such unit will constitute a binding agreement between the tendering limited partner and us on the terms set forth in this Offer to Purchase and the letter of transmittal.

4.   Withdrawal Rights

You may withdraw your tendered units at any time prior to the expiration date, including any extensions thereof, or on or after November 29, 2007 if the units have not been previously accepted for payment. If you properly withdraw all of the units you previously tendered in the offer, the corresponding letter of transmittal, including your release and assignment of future claims contained therein, will be deemed revoked and of no force or effect.

For a withdrawal to be effective, a written notice of withdrawal must be timely received by the Information Agent at one of its addresses set forth on the back cover of this Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered, the number of units to be withdrawn and the name of the registered holder of such units, if different from the person who tendered. In addition, the notice of withdrawal must be signed by the person who signed the letter of transmittal in the same manner as the letter of transmittal was signed.

If purchase of, or payment for, a unit is delayed for any reason, or if we are unable to purchase or pay for a unit for any reason, then, without prejudice to our rights under the offer, tendered units may be retained by the Information Agent; subject, however, to our obligation, pursuant to Rule 14e-1(c) under the Exchange Act, to pay the offer price in respect of units tendered or return those units promptly after termination or withdrawal of our offer.

Any units properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of our offer. However, withdrawn units may be re-tendered at any time prior to the expiration date by following the procedures described in “The Offer — Section 3. Procedure for Tendering Units.”

All questions as to the validity and form (including time of receipt) of notices of withdrawal will be determined by us in our reasonable discretion. Neither we, the Information Agent, nor any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

5.   Extension of Tender Offer Period; Termination; Amendment; No Subsequent Offering Period

We expressly reserve the right, in our reasonable discretion, at any time and from time to time, (i) to extend the period of time during which our offer is open and thereby delay acceptance for payment of, and the payment for, any unit, (ii) to terminate the offer and not accept any units not theretofore accepted for payment or paid for if any of the conditions to the offer are not satisfied, and (iii) to amend our offer in any respect (including, without limitation, by increasing or decreasing the consideration offered, increasing or decreasing the units being sought, or both). We will not assert any of the conditions to the offer subsequent to the expiration of the offer. Notice of any such extension, termination or amendment will promptly be disseminated to you in a manner reasonably designed to inform you of such change. In the case of an extension of the offer, the extension will be followed by a press release or public announcement which will be issued no later than 9:00 a.m., New York City time, on the next business day after the scheduled expiration date of our offer, in accordance with Rule 14e-1(d) under the Exchange Act.

If we extend the offer, or if we delay payment for a unit (whether before or after its acceptance for payment) or are unable to pay for a unit pursuant to our offer for any reason, then, without prejudice to our rights under the offer, the Information Agent may retain tendered units and those units may not be withdrawn except to the extent tendering limited partners are entitled to withdrawal rights as described in “The Offer — Section 4. Withdrawal Rights;” subject, however, to our obligation, pursuant to

29

Rule 14e-1(c) under the Exchange Act, to pay the offer price in respect of units tendered or return those units promptly after termination or withdrawal of the offer.

If we make a material change in the terms of our offer, or if we waive a material condition to our offer, we will extend the offer and disseminate additional tender offer materials to the extent required by Rules 14d-4 and 14e-1 under the Exchange Act. The minimum period during which the offer must remain open following any material change in the terms of the offer, other than a change in price or a change in percentage of securities sought or a change in any dealer’s soliciting fee, if any, will depend upon the facts and circumstances, including the materiality of the change, but generally will be five business days. With respect to a change in price or, subject to certain limitations, a change in the percentage of securities sought or a change in any dealer’s soliciting fee, if any, a minimum of ten business days from the date of such change is generally required to allow for adequate dissemination to limited partners. Accordingly, if, prior to the expiration date, we increase (other than increases of not more than two percent of the outstanding units) or decrease the number of units being sought, or increase or decrease the offer price, and if the offer is scheduled to expire at any time earlier than the tenth business day after the date that notice of such increase or decrease is first published, sent or given to limited partners, the offer will be extended at least until the expiration of such ten business days. As used in this Offer to Purchase, “business day” means any day other than a Saturday, Sunday or a Federal holiday, and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.

Pursuant to Rule 14d-11 under the Exchange Act, subsequent offering periods may be provided in tender offers for “any and all” outstanding units of a partnership. A subsequent offering period is an additional period of from three to twenty business days following the expiration date of the offer, including any extensions, in which limited partners may continue to tender units not tendered in the offer for the offer price. We do not currently intend to offer a subsequent offering period.

Except as described in “Special Factors — Purpose, Alternatives and Reasons for the Offer,” “— Conflicts of Interest and Transactions with Affiliates” and “The Offer — Section 7. Certain Information Concerning Your Partnership,” neither we nor, to the best of our knowledge, any of the persons listed on Annex I attached hereto, (i) beneficially own or have a right to acquire any units, (ii) has effected any transaction in the units in the past 60 days, or (iii) have any contract, arrangement, understanding or relationship with any other person with respect to any securities of your partnership, including, but not limited to, contracts, arrangements, understandings or relationships concerning transfer or voting thereof, joint ventures, loan or option arrangements, puts or calls, guarantees of loans, guarantees against loss or the giving or withholding of proxies. Neither we nor our affiliates intend to tender any units beneficially owned in this offer.

7.   Certain Information Concerning Your Partnership

General.  Your partnership was organized on May 14, 1986 under the laws of the State of Delaware. Its primary business is real estate ownership and related operations. Your partnership was formed for the purpose of operating and holding for investment an apartment complex known as “Riverside Park.” Your partnership’s investment portfolio currently consists of one residential apartment complex. Your partnership currently has approximately 267 limited partners.

General Partner.  The general partner of your partnership is AIMCO/Riverside Park Associates GP, LLC, a wholly owned subsidiary of Aimco/Bethesda Holdings, Inc., a Delaware corporation (“Aimco/Bethesda”), which is an affiliate of Aimco. The principal executive office of the general partner is located at 55 Beattie Place, P.O. Box 1089, Greenville, South Carolina 29602, and its phone number is (864) 239-1000. The names, positions and business addresses of the directors and executive officers of the general partner (which is our affiliate), as well as a biographical summary of the experience of such persons for the past five years or more, are set forth on Annex I attached hereto and are incorporated herein by reference.

Our affiliate serves as manager of the property owned by your partnership. We and the general partner of your partnership received total fees and reimbursements (excluding property management fees) of approximately $646,000 in 2004, $951,000 in 2005 and $2,522,000 in 2006. Total fees and reimbursements (excluding property management fees) for the six months ended June 30, 2007 were approximately $2,672,000. The property manager is entitled to receive 4% of gross receipts from the partnership’s property as compensation for providing property management services. It received property management fees of approximately $568,000 in 2004, $530,000 in 2005 and $494,000 in 2006. Property management fees for the six months ended June 30, 2007 were approximately $227,000.

Ownership and Voting.  We, together with Insignia Financial Group, Inc. (which is our affiliate), own 383.41 units, or 67.74% of the total outstanding units of your partnership. Because we and our affiliate own a majority of the outstanding units and control your partnership’s general partner, we control the outcome of most voting decisions with respect to your partnership. In general, we will vote the units owned by us in whatever manner we deem to be in our best interests, which may not be in the interest of other limited partners. See “Special Factors — Effects of the Offer” and “The Offer — Section 8. Voting Power.”

Investment Objectives and Policies; Sale or Financing of Investments.  In general, your general partner (which is our affiliate) regularly evaluates the partnership’s property by considering various factors, such as the partnership’s financial position and real estate and capital markets conditions. The general partner monitors the property’s specific locale and sub-market conditions (including stability of the surrounding neighborhood), evaluating current trends, competition, new construction and economic changes. It oversees the operating performance of the property and continuously evaluates the physical improvement requirements. In addition, the financing structure for the property (including any prepayment penalties), tax implications, availability of attractive mortgage financing to a purchaser, and the investment climate are all considered. Any of these factors, and possibly others, could potentially contribute to any decision by the general partner to sell, refinance, upgrade with capital improvements or hold the partnership property. After taking into account the foregoing considerations, your general partner has no present intention of seeking a sale of your partnership’s property.

In March 2005, the partnership began a major redevelopment project at Riverside Park Apartments intended to help it compete with other properties in its local market. The redevelopment is expected to consist of renovation and appliance upgrades to each apartment unit and the addition of a new clubhouse and fitness center. The general partner estimates that project costs will be approximately $142,000,000. Based on current redevelopment plans, the general partner expects the redevelopment to be completed in April 2011. The partnership expects to fund the redevelopment from operations, advances

31

from us and our affiliates and third party debt. Although there can be no assurance as to the effect of these expenditures on the future performance of the property, these expenditures are expected to improve the desirability of the property to tenants. Although the future operating results of your partnership and future sales price of the property owned by your partnership are uncertain, the operating performance of your partnership’s property may improve in the future or the private resale market for properties could improve over time, which, in turn, may result in higher property values, making a sale of your partnership’s property a more attractive option in the future. Such values, however, are also a function of the interest rate environment at the time. Another significant factor considered by your general partner is the likely tax consequences of a sale of the property for cash. Such a transaction would likely result in tax liabilities for many limited partners.

Term of Your Partnership.  Under your partnership’s agreement of limited partnership, the term of the partnership will continue until December 31, 2035 unless sooner terminated as provided in the agreement or by law.

Capital Replacements.  Your partnership has an ongoing program of capital improvements, replacements and renovations, including interior and exterior building improvements, cabinet, floor covering and appliance replacements and other replacements and renovations in the ordinary course of business. During the six months ended June 30, 2007, the partnership completed approximately $17,419,000 of capital improvements primarily arising from the redevelopment of Riverside Park Apartments, which includes capitalization of construction period interest of approximately $1,848,000, real estate taxes of approximately $208,000 and other construction period operating costs of approximately $148,000. These improvements were funded from operations, partnership reserves and advances from an affiliate of the general partner. Certain other routine capital expenditures are anticipated during the remainder of 2007. Such capital expenditures will depend on the physical condition of the property as well as anticipated cash flow generated by the property. The additional capital expenditures will be incurred only if cash is available from operations, partnership reserves, or advances from us and our affiliates. To the extent that capital improvements are completed, the partnership’s distributable cash flow, if any, may be adversely affected at least in the short term.

Competition.  There are other residential properties within the market area of your partnership’s property. The number and quality of competitive properties in such an area could have a material effect on the rental market for the apartments at your partnership’s property and the rents that may be charged for such apartments. While Aimco is a significant factor in the United States in the apartment industry, competition for apartments is local. According to data published by the National Multi-Housing Council, we believe Aimco is one of the largest owners and managers of multifamily apartment properties in the United States.

Financial Data.  The selected financial information of your partnership set forth below for the six months ended June 30, 2007 and 2006 is based on unaudited financial statements. The selected financial information of your partnership set forth below for the years ended December 31, 2006, 2005 and 2004 is based on audited financial statements.

Legal Proceedings.  From time to time, your partnership may be a party to a variety of legal proceedings related to its ownership of the property which arise in the ordinary course of business.

8.   Voting Power

Decisions with respect to the day-to-day management of your partnership are the responsibility of the general partner. The general partner of your partnership is our affiliate, and we control the management of your partnership. Under your partnership’s agreement of limited partnership, limited partners holding a majority of the outstanding units must approve certain extraordinary transactions, including the removal of the general partner, most amendments to the partnership agreement and the sale of all or substantially all of your partnership’s assets. We, together with Insignia Financial Group, Inc. (which is our affiliate), own 383.41 units, or 67.74% of the outstanding units of your partnership. Because we and our affiliates own a majority of the outstanding units and control your partnership’s general partner, we control the outcome of most voting decisions with respect to your partnership. See “Special Factors — Effects of the Offer.”

9.   Source of Funds

We expect that approximately $11.8 million will be required to purchase all of the limited partnership units that we are seeking in this offer exclusive of fees and expenses. For more information regarding fees and expenses, see “The Offer — Section 13. Fees and Expenses.”

34

In addition to this offer, we intend to make concurrent offers to acquire interests in several other limited partnerships. If such transactions were fully subscribed for cash, we would be required to pay approximately $30 million for such units. If for some reason we did not have such funds available, we might extend these offers for a period of time sufficient for us to obtain additional funds, or we could terminate the offers. However, we do not expect these offers to be fully subscribed. Additionally, we believe that we will have sufficient cash on hand and available sources of financing to acquire all units tendered pursuant to these offers. As of June 30, 2007, we had cash and cash equivalents of approximately $258 million, and availability under our credit facility of approximately $256.2 million. We intend to repay any amounts borrowed to finance the offer out of future working capital.

We have a $450 million revolving credit facility with a syndicate of financial institutions. The Aimco Operating Partnership, Aimco and AIMCO/Bethesda are the borrowers. The annual interest rate under the credit facility is based on either LIBOR or a base rate, plus, in either case, an applicable margin. The margin ranges between 1.125% and 1.75% in the case of LIBOR-based loans and between 0% and 0.25% in the case of base rate loans, based upon Aimco’s leverage ratio. The default rate of interest for the loan is equal to the rate described above plus 3%. The credit facility matures on May 1, 2009.

10.   Dissenters’ Rights

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

No provisions have been made with regard to the offer to allow you or other limited partners to inspect the books and records of the partnership or to obtain counsel or appraisal services at our expense or at the expense of your partnership. However, you have the right under your partnership’s agreement of limited partnership to obtain a list of the limited partners in your partnership.

11.   Conditions to the Offer

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

•  any change shall have occurred or been threatened in the business, properties, assets, liabilities, indebtedness, capitalization, condition (financial or otherwise), operations, licenses or franchises, management contract, or results of operations or prospects of your partnership or local markets in which your partnership owns or operates its property, including any fire, flood, natural disaster, casualty loss, or act of God that is adverse to your partnership or the value of your units to us, which change would, individually or in the aggregate, result in an adverse effect on net operating income of your partnership of more than $10,000 per year, or a decrease in value of an asset of your partnership, or the incurrence of a liability with respect to your partnership, in an amount in excess of $100,000 (a “Material Adverse Effect”); or

•  there shall have occurred (i) any general suspension of trading in, or limitation on prices for, securities on any national securities exchange or the over-the-counter market in the United States, (ii) a decline in the closing share price of Aimco’s Class A Common Stock of more than 5.0%, measured from the close of business on the last trading day preceding the date of this offer and the close of business on the last trading day preceding the expiration of this offer, (iii) any extraordinary or material adverse change in the financial, real estate or money markets or major equity security indices in the United States such that there shall have occurred at least a 25 basis point increase in LIBOR, or at least a 5.0% decrease in the S&P 500 Index, the Morgan Stanley REIT Index, or the price of the 10-year Treasury Bond or the price of the 30-year Treasury Bond, in each case, measured from the close of business on the last trading day preceding the date of this offer and the close of business on the last trading day preceding the expiration of this offer, (iv) a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States, (v) any limitation (whether or not mandatory) by any governmental authority on, or any other material event which, in either case, could reasonably be expected to affect the extension of credit by banks or other lending institutions, or (vi) in the case of any of the foregoing existing at the time of the commencement of the offer, a material acceleration or worsening thereof; or

12.   Certain Legal Matters

General.  Except as set forth in this Section 12, we are not aware of any licenses or regulatory permits that would be material to the business of your partnership, taken as a whole, and that might be adversely affected by our acquisition of units as contemplated herein, or any filings, approvals or other actions by or with any domestic or foreign governmental authority or administrative or regulatory agency that would be required prior to the acquisition of units by us pursuant to the offer, other than the filing of a Tender Offer Statement and Rule 13e-3 Transaction Statement on Schedule TO with the SEC (which has already been filed) and any required amendments thereto. While there is no present intent to delay the purchase of units tendered pursuant to the offer pending receipt of any such additional approval or the taking of any such action, there can be no assurance that any such additional approval or action, if needed, would be obtained without substantial conditions or that adverse consequences might not result to your partnership or its business, or that certain parts of its business might not have to be disposed of or other substantial conditions complied with in order to obtain such approval or action, any of which could cause us

36

to elect to terminate the offer without purchasing units thereunder. Our obligation to purchase and pay for units is subject to certain conditions, including conditions related to the legal matters discussed in this Section 12.

Antitrust.  We do not believe that the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, is applicable to the acquisition of units contemplated by our offer.

Margin Requirements.  The units are not “margin securities” under the regulations of the Board of Governors of the Federal Reserve System and, accordingly, those regulations generally are not applicable to our offer.

State Laws.  We are not aware of any jurisdiction in which the making of our offer is not in compliance with applicable law. If we become aware of any jurisdiction in which the making of the offer would not be in compliance with applicable law, we will make a good faith effort to comply with any such law. If, after such good faith effort, we cannot comply with any such law, the offer will not be made to (nor will tenders be accepted from or on behalf of) limited partners residing in such jurisdiction. In those jurisdictions with securities or blue sky laws that require the offer to be made by a licensed broker or dealer, the offer shall be made on behalf of us, if at all, only by one or more registered brokers or dealers licensed under the laws of that jurisdiction.
