To the Limited Partners of AIMCO Properties, L.P.:

These consent solicitation materials are being sent to you and the other Limited Partners of AIMCO Properties, L.P. (the “Partnership”) to solicit your consent to a proposed amendment to the Partnership’s agreement of limited partnership. This consent solicitation is made on behalf of AIMCO-GP, Inc., the general partner of the Partnership (the “General Partner”). The Board of Directors of the General Partner has unanimously approved the proposed amendment to the Partnership’s agreement of limited partnership.

Aimco has announced a plan to spin off its redevelopment and development business and portfolio (which represents less than 10% of Aimco’s existing GAV) (the “Spin-Off Transaction”). The Spin-Off Transaction will result in two, focused and independent companies: (x)                      (“Spinco”), which is expected to be, a best-in-class, pure-play multifamily REIT, which is expected to have a high-quality portfolio diversified by market and price, an unequaled record of flat cost of equity for the past 10 years, high same store operating margins, high customer satisfaction and retention, a strong balance sheet and low weighted average net interest expense, the lowest general and administrative and offsite costs in the sector, and low execution right with no development or redevelopment activity; and (y) Aimco, which is expected to own the growing business of development and redeveloping apartment communities while also pursuing other accretive transactions.

In order to effect the potential Spin-Off Transaction, a number of restructuring steps will occur prior to the closing of the Spin-Off Transaction (the “Restructuring”). As a result of the Restructuring, Spinco will own Aimco’s interests in the Partnership, while Aimco is expected to hold interests in a newly-formed operating partnership, Durango OP, LP, which will own the redevelopment and development business and a portfolio of assets that is expected to include 11 stabilized multi-family properties, as well as four other investments, which are: Aimco’s loan to, and equity option in, the partnership owning Parkmerced Apartments located in southwest San Francisco, California; Hamilton on the Bay, a multi-family property located on the waterfront in Miami, Florida with 271 apartment homes as well as the land and zoning to construct 389 additional apartment homes; 1001 Brickell Bay Tower, a 350,000 square foot office building located in Miami, Florida; and the Yacht Club property adjacent to 1001 Brickell. Therefore, at the time the Spin-Off Transaction is consummated, Aimco will no longer, and Spinco will, reflect the value of the Partnership. The proposed amendment is intended to, among other things, replace certain references to the capital stock of Aimco with references to the capital stock of Spinco and replace certain references to obligations of Aimco with references to obligations of Spinco, and certain other changes as reflected in the conformed exhibit.

The General Partner believes that the proposed amendment is in the best interests of the Partnership and its Limited Partners, and recommends that you “CONSENT” to the proposed amendment. Your vote on this matter is very important. We urge you to promptly complete, sign and return the enclosed consent form using the enclosed postage-paid reply envelope as soon as possible and no later than the expiration date of the consent solicitation period which is                      , 2020.

Sincerely,

AIMCO-GP, Inc.,

General Partner

CONSENT SOLICITATION STATEMENT

This Consent Solicitation Statement is being furnished to Limited Partners of AIMCO Properties, L.P., a Delaware limited partnership (the “Partnership”), who hold Partnership Common Units (“OP Units”), or any of the other classes of Partnership Units which vote together with the OP Units as Voting Units (as defined in the existing Partnership Agreement (as defined below)).

This consent solicitation (the “Consent Solicitation”) is made by AIMCO-GP, Inc., the general partner of the Partnership (the “General Partner”). This Consent Solicitation Statement is first being mailed to holders of Voting Units on or about                      , 2020.

What is the purpose of this Consent Solicitation?

The General Partner is asking Limited Partners who hold Voting Units to consent to the proposed amendment (the “Amendment”) to the Partnership’s Fifth Amended and Restated Agreement of Limited Partnership (as amended to date, the “Partnership Agreement”). “The Proposal” would, in connection with a potential spin-off transaction (the “Spin-Off Transaction”), as a result of which the Partnership would no longer be a subsidiary of Apartment Investment and Management Company (“Aimco”) and would instead be a subsidiary of Aimco-LP, Inc., a Maryland corporation expected to be renamed                      (“Spinco”) and publicly traded and listed on the New York Stock Exchange, among other things, replace certain references to the capital stock of Aimco with references to the capital stock of Spinco and replace certain references to obligations of Aimco with references to obligations of Spinco, including with respect to the exchangeability and redeemability of common limited partnership units of the Partnership (“Common Units”) and as such terms are used in any partnership unit designation. If the Amendment is approved by the Limited Partners, the General Partner may, in its sole discretion, (x) amend the Partnership Agreement to reflect the Amendment, (y) amend and restate the Partnership Agreement to reflect the Amendment and any other amendments duly approved prior to such time in accordance with the terms of the existing Partnership Agreement or (z) not amend or amend and restate the Partnership to reflect the Amendment (in which case the partners shall remain bound by the terms of the existing Partnership Agreement). Attached as Exhibit A is an illustrative Sixth Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P. (excluding exhibits) that reflects the Amendment, and is marked to show changes, which includes the amended defined terms of “Previous General Partner” to mean Spinco and “REIT Share” to mean Class A Common Stock, par value $.01 per share, of Spinco. This Consent Solicitation Statement includes information that the General Partner is required to provide you under the rules of the Securities and Exchange Commission (“SEC”).

Who is entitled to consent?

You will be entitled to vote on the Proposal if you held Voting Units as of the close of business on                      , 2020 (the “Record Date”). As of the Record Date,                 Voting Units were issued, outstanding and entitled to vote on the Proposal. Each holder of a Voting Unit is entitled to one vote per unit. The General Partner expects that some of its employees may solicit Limited Partners personally and by telephone. None of these employees will receive any additional or special compensation for doing this.

What consent is required?

Approval of the Proposal requires the affirmative consent (the “Required Consent”) of Limited Partners holding more than fifty percent (50%) of the outstanding Voting Units held by all Limited Partners other than any partner owned by Aimco (collectively, the “Voting Limited Partners”).

1

If approved, when will the Amendment be effective?

The Amendment will be effective only after the receipt of the Required Consent, which may occur prior to the Expiration Date (defined below) if the Required Consent is received before then, and only after the General Partner, in its sole discretion, executes an amendment to the existing Partnership Agreement (or an amended and restated Partnership Agreement) reflecting the Amendment, which is expected to occur substantially concurrently with the potential Spin-Off Transaction. The General Partner will disclose the results of this Consent Solicitation promptly after the Expiration Date, or receipt of the Required Consent if the Required Consent is received before then. If approved, and executed by the General Partner in its sole discretion, all Limited Partners will be bound by the terms of the Amendment, whether or not they consent to the Proposal. Even if the Required Consent is received, the General Partner shall retain the ability to, in its sole and absolute discretion, including in the event that the potential Spin-Off Transaction is not consummated, not effect the Amendment, in which case the partners shall remain bound by the terms of the existing Partnership Agreement.

Who pays for the cost of the Consent Solicitation?

The Partnership will bear the costs of preparing and mailing the Consent Solicitation Statement. The Partnership has also made arrangements with Alliance Advisors to assist in the Consent Solicitation process and communicating with the Limited Partners and estimates that it will pay them a fee of approximately $                 plus out-of-pocket fees and expenses for these services. The Consent Solicitation process may also be conducted by employees of the Partnership, who will not be additionally or specially compensated for their services in this regard.

When is the deadline to deliver my consent?

The Consent Solicitation will expire at, and your consent must be received by,                      , 2020 (the “Expiration Date”). You may revoke your consent at any time prior to the Partnership’s receipt of the Required Consent.

How do I consent?

Limited Partners must sign and return the consent form accompanying this Consent Solicitation Statement in the postage-paid envelope provided, or by fax to the number provided in the consent form, in order to vote on the Proposal. Because the affirmative consent of Limited Partners holding more than fifty percent (50%) of the outstanding Voting Units held by all Voting Limited Partners is required to approve the Proposal, returning a consent form marked “Abstains” for the Proposal will equate to a vote against the Proposal. PURSUANT TO THE PARTNERSHIP AGREEMENT, FAILURE TO SIGN AND RETURN A CONSENT FORM BY THE EXPIRATION DATE WILL CONSTITUTE A CONSENT IN FAVOR OF THE PROPOSAL.

A consent form that is signed but not marked “Consents,” “Withholds Consent” or “Abstains” with respect to the Proposal will be treated as a consent in favor of the Proposal. Limited Partners may revoke their consents at any time prior to the Expiration Date by dating, signing and delivering to the Partnership a written notice that clearly expresses the revocation of consent, or by delivering a properly executed, subsequently dated consent form withholding a previously granted consent. However, any revocation received after the Partnership’s receipt of the Required Consent will not be effective.

Do I have any appraisal rights?

Neither Delaware law nor the Partnership Agreement requires that the Limited Partners be entitled to appraisal rights in connection with the Proposal, and no such appraisal rights will be afforded to Limited Partners who withhold consent to the Proposal.

Whom do I contact if I have questions?

Please direct all questions to AIMCO Properties, L.P., c/o Alliance Advisors, 200 Broadacres Drive, 3rd Floor, Bloomfield, NJ 07003, or call toll free (844) 876-6185.

THE PROPOSAL

Background

Aimco is a self-administered and self-managed real estate investment trust (“REIT”), focused on the ownership, management, redevelopment and some development of quality apartment communities located in several of the largest markets in the United States. Those markets include: Atlanta; the San Francisco Bay Area; Boston; Chicago; Denver; Greater New York City; Greater Washington, D.C.; Los Angeles; Miami/Dade County; Philadelphia; San Diego; and Seattle.

Aimco is currently organized as an umbrella partnership REIT, or UPREIT, with the Partnership as Aimco’s operating partnership. Aimco, through its wholly owned subsidiaries, AIMCO-GP, Inc. and Aimco-LP, Inc., owns a majority of the ownership interests in the Partnership. Aimco conducts all of its business and owns all of its assets through the Partnership..

Under the agreement, after a one year holding period, holders of OP Units have the right (the “Redemption Right”) to tender their units for redemption and receive, in exchange for each unit, either (i) one share of Aimco’s Class A Common Stock (“Aimco common stock”), or (ii) cash in an amount equal to the value of one share of Aimco common stock at the time, with the form of consideration at the election of the Partnership. Also, the Partnership makes quarterly distributions to holders of OP Units in an amount per unit equal to the per share dividend paid at that time to holders of Aimco common stock (an “Aimco dividend equivalent distribution”).

Proposed Amendment

The board of directors of Aimco has announced a plan to spin off its redevelopment and development business and portfolio (which represents less than 10% of Aimco’s existing GAV). The Spin-Off Transaction will result in two, focused and independent companies: (x) Spinco, which is expected to be, a best-in-class, pure-play multifamily REIT, which is expected to have a high-quality portfolio diversified by market and price, an unequaled record of flat cost of equity for the past 10 years, high same store operating margins, high customer satisfaction and retention, a strong balance sheet and low weighted average net interest expense, the lowest general and administrative and offsite costs in the sector, and low execution right with no development or redevelopment activity; and (y) Aimco, which is expected to own the growing business of development and redeveloping apartment communities while also pursuing other accretive transactions. Spinco’s business plan is expected to: (i) significantly reduce risk for Spinco by avoiding development and redevelopment and lowering leverage and maintaining a safe balance sheet, (ii) position Spinco as a simple, transparent and predictable company, (iii) structured to increase Spinco’s current income as measured by Funds From Operation (FFO), (iv) allows for increased dividends for Spinco because of its higher, more predictable income, (v) permit Development Company to realize the value of investments that are complex or require time to monetize, while being well capitalized to complete projects underway and have sufficient operating cash flow to cover offsite costs and debt service and (vi) provide Spinco an opportunity to refresh its tax basis thereby enhancing its ability to manage its portfolio with minimal tax friction.

In order to effect the potential Spin-Off Transaction, a number of restructuring steps will occur prior to the closing of the Spin-Off Transaction (the “Restructuring”). As a result of the Restructuring, Spinco will own Aimco’s interests in the Partnership, while Aimco is expected to hold interests in a newly-formed operating partnership, Durango OP, LP, which will own the redevelopment and development business and a portfolio of

3

assets that is expected to include 11 stabilized multi-family properties, primarily located in the Boston and San Diego areas, to provide cash flows to help meet its on-going liquidity needs, as well as four other investments, which are: Aimco’s loan to, and equity option in, the partnership owning Parkmerced Apartments located in southwest San Francisco, California; Hamilton on the Bay, a multi-family property located on the waterfront in Miami, Florida with 271 apartment homes as well as the land and zoning to construct 389 additional apartment homes; 1001 Brickell Bay Tower, a 350,000 square foot office building located in Miami, Florida; and the Yacht Club property adjacent to 1001 Brickell. Therefore, at the time the Spin-Off Transaction is consummated, Aimco will no longer, and Spinco will, reflect the value of the Partnership. Accordingly, the Amendment is necessary to preserve the value of the Redemption Rights.

The Amendment is intended to amend the Partnership Agreement to reflect the actual value of the Partnership after giving effect to the Restructuring steps. The material amendments that will be reflected in the Amendment will:

• amend the defined term “Previous General Partner” to mean Spinco (rather than Aimco);

• amend the defined term “REIT Share” to mean the Class A Common Stock, par value $.01 per share, of Spinco (rather than Aimco); and

• amend the definition of “Special Limited Partner” to mean Spinco and certain of its REIT subsidiaries that hold units of the Partnership (rather than only AIMCO-LP Trust, the predecessor to Aimco-LP, Inc.).

Attached as Exhibit A is an illustrative Sixth Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P. (excluding exhibits thereto) that reflects the Amendment, and is marked to show changes.

Certain Considerations

By approving the Proposal, the Limited Partners would allow the General Partner to make certain amendments to the Partnership Agreement, if the Spin-Off Transaction occurs, to address the resulting change in ownership of the Partnership as a result of the Restructuring and the Spin-Off Transaction whereby the Partnership would become a subsidiary of Spinco, among other things, by replacing certain references to the capital stock of Aimco with references to the capital stock of Spinco and replacing certain references to obligations of Aimco with references to obligations of Spinco, including with respect to the exchangeability and redeemability of Common Units and as such terms are used in any partnership unit designation, and by making certain other changes as reflected in Exhibit A. Even if the Required Consent is received, the General Partner shall retain the ability to, in its sole and absolute discretion, including in the event that the potential Spin-Off Transaction is not consummated, not effect the Amendment, in which case the partners shall remain bound by the terms of the existing Partnership Agreement.

Recommendation of the General Partner

The General Partner believes that the Proposal will allow Aimco OP unitholders to realize the benefit of the Spin-Off Transaction, and that the Proposal is in the best interests of the Partnership and its Limited Partners, to the extent that the Spin-Off Transaction is consummated, and recommends that the Voting Limited Partners “CONSENT” to the Proposal.

FORWARD-LOOKING STATEMENTS

This Consent Solicitation Statement includes forward-looking statements within the meaning of the federal securities laws. Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, assumptions, strategies, future events or performance (often, but not always, through the use of words or phrases such as result, are expected to, will continue, is anticipated, aim, believe, will, could, should, would, estimated, may, plan, potential, future, projection, goals, target, outlook, predict and intend or words of similar meaning) are not statements of historical facts and may be forward looking. Forward-looking statements involve estimates, assumptions and uncertainties. Accordingly, any such statements should be read together with the risk factors included in Part I, Item 1A. Risk Factors of the Annual Report on Form 10-K of Aimco and the Partnership for the fiscal year ended December 31, 2019, filed with the SEC on February 24, 2020 (the “Form 10-K”), the risk factors included in Part II, Item 1A. Risk Factors of the Quarterly Report on Form 10-Q of Aimco and the Partnership for the quarterly period ended March 31, 2020, filed with the SEC on May 11, 2020 (“Q1 Form 10-Q”) and the risk factors included in Part II, Item 1A.

Any forward-looking statement speaks only as of the date on which such statement is made, and neither the General Partner, Aimco nor the Partnership undertake any obligation to update any forward-looking statement to reflect events or circumstances, including unanticipated events, after the date on which such statement is made, unless otherwise required by law. New factors emerge from time to time and it is not possible for management to predict all of such factors, nor can it assess the impact of each such factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained or implied in any forward-looking statement.

THIS FIFTHSIXTH AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF AIMCO PROPERTIES, L.P., dated as of July 29, 1994,as amended and restated as of April  8[—], 20192020 (the “Amendment Date”), is entered into by and among Apartment Investment and Management Company[SPINCO], a Maryland corporation (the “Previous General Partner”), REIT Sub 1, REIT Sub 2 (REIT Sub 1, together with REIT Sub 2 and the Previous General Partner (solely in respect of its status as a Limited Partner), the “Special Limited Partners”), AIMCO-GP, Inc., a Delaware corporation, AIMCO-LP Trust, a Delaware statutory trust (the “Special Limited Partner”), and the other Limited Partners (as defined below).

WHEREAS, AIMCO-GP, Inc., in its capacity as the General Partner, has obtained, to the extent required under the Fifth Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P., Consent of the Limited Partners, and approved an amendment and restatement of the Agreement of Limited Partnership of AIMCO Properties, L.P. on the terms set forth herein.; and

WHEREAS, the Preferred Return (as defined in the Fifth Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P.) was an amount equal to zero as of immediately prior to the effectiveness of the restatement of this Agreement on the Amendment Date.

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE 1

DEFINED TERMS

The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

“Act” means the Delaware Revised Uniform Limited Partnership Act, as it may be amended from time to time, and any successor to such statute.

“Actions” has the meaning set forth in Section 7.7 hereof.

“Additional Funds” has the meaning set forth in Section 4.3A hereof.

“Additional Limited Partner” means a Person who is admitted to the Partnership as a Limited Partner pursuant to Section 4.2 and Section 12.2 hereof and who is shown as such on the books and records of the Partnership.

“Adjusted Capital Account Deficit” means, with respect to any Holder, the deficit balance, if any, in such Holder’s Capital Account as of the end of the relevant Fiscal Year, after giving effect to the following adjustments:

(i)    decrease such deficit by any amounts that such Holder is obligated to restore pursuant to this Agreement or by operation of law upon liquidation of such Holder’s Partnership Interest or is deemed to be obligated to restore pursuant to the penultimate sentence of each of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5); and

(ii)    increase such deficit by the items described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6).

1

The foregoing definition of “Adjusted Capital Account Deficit” is intended to comply with the provisions of Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

“Adjustment Factor” means 1.0; provided, however, that in the event that:

(i)    the Previous General Partner (a) declares or pays a dividend on its outstanding REIT Shares in REIT Shares or makes a distribution to all holders of its outstanding REIT Shares in REIT Shares, (b) splits or subdivides its outstanding REIT Shares or (c) effects a reverse stock split or otherwise combines its outstanding REIT Shares into a smaller number of REIT Shares, the Adjustment Factor shall be adjusted by multiplying the Adjustment Factor previously in effect by a fraction, (i) the numerator of which shall be the number of REIT Shares issued and outstanding on the record date for such dividend, distribution, split, subdivision, reverse split or combination (assuming for such purposes that such dividend, distribution, split, subdivision, reverse split or combination has occurred as of such time) and (ii) the denominator of which shall be the actual number of REIT Shares (determined without the above assumption) issued and outstanding on the record date for such dividend, distribution, split, subdivision, reverse split or combination;

(ii)    the Previous General Partner distributes any rights, options or warrants to all holders of its REIT Shares to subscribe for or to purchase or to otherwise acquire REIT Shares (or other securities or rights convertible into, exchangeable for or exercisable for REIT Shares) at a price per share less than the Value of a REIT Share on the record date for such distribution (each a “Distributed Right”), then the Adjustment Factor shall be adjusted by multiplying the Adjustment Factor previously in effect by a fraction (a) the numerator of which shall be the number of REIT Shares issued and outstanding on the record date plus the maximum number of REIT Shares purchasable under such Distributed Rights and (b) the denominator of which shall be the number of REIT Shares issued and outstanding on the record date plus a fraction (1) the numerator of which is the maximum number of REIT Shares purchasable under such Distributed Rights times the minimum purchase price per REIT Share under such Distributed Rights and (2) the denominator of which is the Value of a REIT Share as of the record date; provided, however, that, if any such Distributed Rights expire or become no longer exercisable, then the Adjustment Factor shall be adjusted, effective retroactive to the date of distribution of the Distributed Rights, to reflect a reduced maximum number of REIT Shares or any change in the minimum purchase price for the purposes of the above fraction; and

(iii)    the Previous General Partner shall, by dividend or otherwise, distribute to all holders of its REIT Shares evidences of its indebtedness or assets (including securities, but excluding any dividend or distribution referred to in subsection (i) above), which evidences of indebtedness or assets relate to assets not received by the Previous General Partner, the General Partner and/or the Special Limited PartnerPartners pursuant to a pro rata distribution by the Partnership, then the Adjustment Factor shall be adjusted to equal the amount determined by multiplying the Adjustment Factor in effect immediately prior to the close of business on the date fixed for determination of shareholders entitled to receive such distribution by a fraction (i) the numerator shall be such Value of a REIT Share on the date fixed for such determination and (ii) the denominator shall be the Value of a REIT Share on the dates fixed for such determination less the then fair market value (as determined by the General Partner, whose determination shall be conclusive) of the portion of the evidences of indebtedness or assets so distributed applicable to one REIT Share.

Any adjustments to the Adjustment Factor shall become effective immediately after the effective date of such event, retroactive to the record date, if any, for such event. Notwithstanding the foregoing, in the event of any transaction described above with respect to REIT Shares that would otherwise require an adjustment to the Adjustment Factor, no such adjustment shall be made if the Partnership concurrently effects a similar and proportional transaction with respect to the Partnership Common Units. If the Previous General Partner makes an Elective Dividend, no adjustment to the Adjustment Factor shall be made if the Partnership concurrently makes a distribution to Holders of Partnership Common Units in an amount per Unit consisting of either (x) (i) a number of Partnership Common Units (or fraction thereof) equal to the aggregate number of REIT Shares paid as a dividend with respect to all REIT Shares, divided by the total number of REIT Shares outstanding as of the

2

record date for such dividend, and (ii) cash in an amount equal to the aggregate amount of cash paid as a dividend with respect to all REIT Shares, divided by the total number of REIT Shares outstanding as of the record date for such dividend, or (y) cash in an amount equal to the aggregate value, as determined in good faith by the General Partner, of both the REIT Shares and the cash paid as a dividend with respect to all REIT Shares, divided by the total number of REIT Shares outstanding as of the record date for such dividend (the portion of such cash amount in clause (y) that is attributable to the value of the REIT Shares paid as a dividend is referred to herein as the “Elective Dividend Cash Payment”). For illustrative purposes, examples of adjustments to the Adjustment Factor are set forth on Exhibit B attached hereto.

“Affiliate” means, with respect to any Person, any Person directly or indirectly controlling or controlled by or under common control with such Person. For the purposes of this definition, “control” when used with respect to any Person means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such Person, whether through the ownership of voting securities, by contract or otherwise, and the terms “controlling” and “controlled” have meanings correlative to the foregoing.

(2)    Second, any remaining Net Income to each Holder in proportion to, and to the extent that, the amount of cumulative Net Loss previously allocated to such Holder exceeds the cumulative amount of Net Income previously allocated to such Holder pursuant to this Section 6.2A(2), in each case after the Amendment Date; and

26

(3)    Third, with respect to all other Net Income, the Non-Aimco Non-[SPINCO] Holders Sharing Percentage to the Non-AimcoNon-[SPINCO] Holders, and the Aimco[SPINCO] Partners Sharing Percentage to the Aimco[SPINCO] Partners, on a pari passu basis.

B.     Net Loss. Net Loss shall be allocated, subject, however, to the limitation set forth in Section 6.2C, to the Non-Aimco Non-[SPINCO] Holders in proportion to the Non-AimcoNon-[SPINCO] Holders Sharing Percentage, and to the Aimco[SPINCO] Partners in proportion to the Aimco[SPINCO] Partners Sharing Percentage, on a pari passu basis.

C.     Net Loss Limitation. Any Net Loss allocated pursuant to Section 6.2B will not exceed the maximum amount of Net Loss that can be so allocated without causing any Holder to have an Adjusted Capital Account Deficit at the end of any Fiscal Year. In the event that any but not all of the Holders would have an Adjusted Capital Account Deficit as a consequence of an allocation of Net Loss pursuant to Section 6.2B, the limitation set forth in the immediately preceding sentence will be applied on a Holder-by-Holder basis so as to allocate the maximum permissible Net Loss to each Holder under Treasury Regulation Section 1.704-1(b)(2)(ii)(d).

D.     Liquidating Event. If a Liquidating Event occurs in a Partnership taxable year, Net Income and Net Loss (or, if necessary, separate items of income, gain, loss and deduction constituting such Net Income and Net Loss) for such taxable year and any prior taxable years (to the extent permitted by Section 761(c) of the Code) shall be allocated among the Holders in such amounts as will cause, to the greatest extent possible, the Capital Account of each Non-Aimco Non-[SPINCO] Holder to equal the amount such Non-AimcoNon-[SPINCO] Holder would be entitled to receive were such Holder to require the Partnership to redeem all of such Holder’s Partnership Common Units pursuant to Section 8.6. If the Gross Asset Values of the Partnership’s assets are adjusted in accordance with subparagraph (b) of the definition of “Gross Asset Value,” after items are allocated pursuant to Sections 6.2A(1) and (2) and Section 6.2B, such adjustments shall be allocated in accordance with this Section 6.2D.

Notwithstanding anything to the contrary in this Agreement, the Partnership Representative in its discretion is expressly authorized to take any action necessary or appropriate to comply with the Partnership Audit Procedures, and to appropriately allocate the burden of any assessments thereunder among the Partners (as determined in the sole good faith judgment of the General Partner).

Section 6.3    Additional Allocation Provisions. Notwithstanding the foregoing provisions of this Article 6:

A.     Intentionally Omitted.

B.     Regulatory Allocations.

(1)    Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f), notwithstanding the provisions of Section 6.2 hereof, or any other provision of this Article 6, if there is a net decrease in Partnership Minimum Gain during any Fiscal Year, each Holder of Partnership Common Units shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Holder’s share of the net decrease in Partnership Minimum Gain, as determined under Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Holder pursuant thereto. The items to be allocated shall be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 6.3B(1) is intended to qualify as a “minimum gain chargeback” within the meaning of Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

(2)    Partner Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4) or in Section 6.3B(1) hereof, if there is a net decrease in Partner Minimum Gain

27

attributable to a Partner Nonrecourse Debt during any Fiscal Year, each Holder of Partnership Common Units who has a share of the Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Holder’s share of the net decrease in Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.7042(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each General Partner, Limited Partner and other Holder pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 6.3B(2) is intended to qualify as a “chargeback of partner nonrecourse debt minimum gain” within the meaning of Regulations Section 1.704-2(i) and shall be interpreted consistently therewith.

(3)    Nonrecourse Deductions and Partner Nonrecourse Deductions. Any Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Holders of Partnership Common Units in accordance with their Partnership Common Units. Any Partner Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Holder(s) who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable, in accordance with Regulations Section 1.704-2(i).

(4)    Qualified Income Offset. If any Holder of Partnership Common Units unexpectedly receives an adjustment, allocation or distribution described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be allocated, in accordance with Regulations Section 1.704-1(b)(2)(ii)(d), to such Holder in an amount and manner sufficient to eliminate, to the extent required by such Regulations, the Adjusted Capital Account Deficit of such Holder as quickly as possible, provided that an allocation pursuant to this Section 6.3B(4) shall be made if and only to the extent that such Holder would have an Adjusted Capital Account Deficit after all other allocations provided in this Article 6 have been tentatively made as if this Section 6.3B(4) were not in the Agreement. It is intended that this Section 6.3B(4) qualify and be construed as a “qualified income offset” within the meaning of Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(5)    Gross Income Allocation. In the event that any Holder of Partnership Common Units has a deficit Capital Account at the end of any Fiscal Year that is in excess of the sum of (1) the amount (if any) that such Holder is obligated to restore to the Partnership upon complete liquidation of such Holder’s Partnership Interest (including, the Holder’s interest in outstanding Partnership Preferred Units and other Partnership Units) and (2) the amount that such Holder is deemed to be obligated to restore pursuant to the penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Holder shall be specially allocated items of Partnership income and gain in the amount of such excess to eliminate such deficit as quickly as possible, provided that an allocation pursuant to this Section 6.3B(5) shall be made if and only to the extent that such Holder would have a deficit Capital Account in excess of such sum after all other allocations provided in this Article 6 have been tentatively made as if this Section 6.3B(5) and Section 6.3B(4) hereof were not in the Agreement.

(6)    Section 754 Adjustment. To the extent that an adjustment to the adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Regulations Section 1.704-1(b)(2) (iv)(m)(2) or Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Holder of Partnership Common Units in complete liquidation of its interest in the Partnership, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such gain or loss shall be specially allocated to the Holders in accordance with their Partnership Common Units in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Holders to whom such distribution was made in the event that Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

28

(7)    Curative Allocations. The allocations set forth in Sections 6.3B(1), (2), (3), (4), (5) and (6) hereof (the “Regulatory Allocations”) are intended to comply with certain regulatory requirements, including the requirements of Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding the provisions of Section 6.1 hereof, the Regulatory Allocations shall be taken into account in allocating other items of income, gain, loss and deduction among the Holders of Partnership Common Units so that to the extent possible without violating the requirements giving rise to the Regulatory Allocations, the net amount of such allocations of other items and the Regulatory Allocations to each Holder of a Partnership Common Unit shall be equal to the net amount that would have been allocated to each such Holder if the Regulatory Allocations had not occurred.

C.     Allocation of Excess Nonrecourse Liabilities. For purposes of determining a Holder’s proportional share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Regulations Section 1.752-3(a)(3), each Holder’s interest in Partnership profits shall be such Holder’s share of Partnership Common Units.

Section 6.4    Tax Allocations.

A.     In General. Except as otherwise provided in this Section 6.4, for income tax purposes under the Code and the Regulations each Partnership item of income, gain, loss and deduction (collectively, “Tax Items”) shall be allocated among the Holders of Partnership Common Units in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Sections 6.2 and 6.3 hereof.

B.     Allocations Respecting Section 704(c) Revaluations. Notwithstanding Section 6.4A hereof, Tax Items with respect to Property that is contributed to the Partnership with a Gross Asset Value that varies from its basis in the hands of the contributing Partner immediately preceding the date of contribution shall be allocated among the Holders of Partnership Common Units for income tax purposes pursuant to Regulations promulgated under Code Section 704(c) so as to take into account such variation. The Partnership shall account for such variation under any method approved under Code Section 704(c) and the applicable Regulations as chosen by the General Partner, including, without limitation, the “traditional method” as described in Regulations Section 1.704-3(b). In the event that the Gross Asset Value of any partnership asset is adjusted pursuant to subsection (b) of the definition of “Gross Asset Value” (provided in Article 1 hereof), subsequent allocations of Tax Items with respect to such asset shall take account of the variation, if any, between the adjusted basis of such asset and its Gross Asset Value in the same manner as under Code Section 704(c) and the applicable Regulations.

A.     To the fullest extent permitted by applicable law, the Partnership shall indemnify each Indemnitee from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorney’s fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Partnership (“Actions”) as set forth in this Agreement in which such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise; provided, however, that the Partnership shall not indemnify an Indemnitee (i) for willful misconduct or a knowing violation of the law or (ii) for any transaction for which such Indemnitee received an improper personal benefit in violation or breach of any provision of this Agreement. Without limitation, the foregoing indemnity shall extend to any liability of any Indemnitee, pursuant to a loan guaranty or otherwise, for any indebtedness of the Partnership or any Subsidiary of the Partnership (including, without limitation, any indebtedness which the Partnership or any Subsidiary of the Partnership has assumed or taken subject to), and the General Partner is hereby authorized and empowered, on behalf of the Partnership, to enter into one or more indemnity agreements consistent with the provisions of this Section 7.7 in favor of any Indemnitee having or potentially having liability for any such indebtedness. It is the intention of this Section 7.7A that the Partnership indemnify each Indemnitee to the fullest extent permitted by law. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Indemnitee did not meet the requisite standard of conduct set forth in this Section 7.7A. The termination of any proceeding by conviction of an Indemnitee or upon a plea of nolo contendere or its equivalent

35

by an Indemnitee, or an entry of an order of probation against an Indemnitee prior to judgment, does not create a presumption that such Indemnitee acted in a manner contrary to that specified in this Section 7.7A with respect to the subject matter of such proceeding. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, and neither the General Partner nor any Limited Partner shall have any obligation to contribute to the capital of the Partnership or otherwise provide funds to enable the Partnership to fund its obligations under this Section 7.7.

B.     To the fullest extent permitted by law, expenses incurred by an Indemnitee who is a party to a proceeding or otherwise subject to or the focus of or is involved in any Action shall be paid or reimbursed by the Partnership as incurred by the Indemnitee in advance of the final disposition of the Action upon receipt by the Partnership of (i) a written affirmation by the Indemnitee of the Indemnitee’s good faith belief that the standard of conduct necessary for indemnification by the Partnership as authorized in this Section 7.7AB has been met, and (ii) a written undertaking by or on behalf of the Indemnitee to repay the amount if it shall ultimately be determined that the standard of conduct has not been met.

C.     The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Partners, as a matter of law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee unless otherwise provided in a written agreement with such Indemnitee or in the writing pursuant to which such Indemnitee is indemnified.

D.     The Partnership may, but shall not be obligated to, purchase and maintain insurance, on behalf of any of the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

E.     Any liabilities which an Indemnitee incurs as a result of acting on behalf of the Partnership or the General Partner (whether as a fiduciary or otherwise) in connection with the operation, administration or maintenance of an employee benefit plan or any related trust or funding mechanism (whether such liabilities are in the form of excise taxes assessed by the IRS, penalties assessed by the Department of Labor, restitutions to such a plan or trust or other funding mechanism or to a participant or beneficiary of such plan, trust or other funding mechanism, or otherwise) shall be treated as liabilities or judgments or fines under this Section 7.7, unless such liabilities arise as a result of (i) such Indemnitee’s intentional misconduct or knowing violation of the law, or (ii) any transaction in which such Indemnitee received a personal benefit in violation or breach of any provision of this Agreement or applicable law.

F.     In no event may an Indemnitee subject any of the Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

G.     An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

H.     The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 7.7 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the Partnership’s liability to any Indemnitee under this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

36

I.     It is the intent of the Partners that any amounts paid by the Partnership to the General Partner pursuant to this Section 7.7 shall be treated as “guaranteed payments” within the meaning of Code Section 707(c).

Section 7.8    Liability of the General Partner.

A.     Notwithstanding anything to the contrary set forth in this Agreement, neither the General Partner nor any of its directors or officers shall be liable or accountable in damages or otherwise to the Partnership, any Partners or any Assignees for losses sustained, liabilities incurred or benefits not derived as a result of errors in judgment or mistakes of fact or law or of any act or omission if the General Partner or such director or officer acted in good faith.

B.     The Limited Partners expressly acknowledge that the General Partner is acting for the benefit of the Partnership, the Limited Partners and the General Partner’s shareholders collectively and that the General Partner is under no obligation to give priority to the separate interests of the Limited Partners or the General Partner’s shareholders (including, without limitation, the tax consequences to Limited Partners, Assignees or the General Partner’s shareholders) in deciding whether to cause the Partnership to take (or decline to take) any actions.

C.     Subject to its obligations and duties as General Partner set forth in Section 7.1A hereof, the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its employees or agents (subject to the supervision and control of the General Partner). The General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by it in good faith.

D.     Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the General Partner’s, and its officers’ and directors’, liability to the Partnership and the Limited Partners under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

E.     Notwithstanding anything herein to the contrary, except for fraud, willful misconduct or gross negligence, or pursuant to any express indemnities given to the Partnership by any Partner pursuant to any other written instrument, no Partner shall have any personal liability whatsoever, to the Partnership or to the other Partner(s), for the debts or liabilities of the Partnership or the Partnership’s obligations hereunder, and the full recourse of the other Partner(s) shall be limited to the interest of that Partner in the Partnership. To the fullest extent permitted by law, no officer, director or shareholder of the General Partner shall be liable to the Partnership for money damages except for (i) active and deliberate dishonesty established by a non-appealable final judgment or (ii) actual receipt of an improper benefit or profit in money, property or services. Without limitation of the foregoing, and except for fraud, willful misconduct or gross negligence, or pursuant to any such express indemnity, no property or assets of any Partner, other than its interest in the Partnership, shall be subject to levy, execution or other enforcement procedures for the satisfaction of any judgment (or other judicial process) in favor of any other Partner(s) and arising out of, or in connection with, this Agreement. This Agreement is executed by the officers of the General Partner solely as officers of the same and not in their own individual capacities.

F.     To the extent that, at law or in equity, the General Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or the Limited Partners, the General Partner shall not be liable to the Partnership or to any other Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict the duties and liabilities of the General Partner otherwise existing at law or in equity, are agreed by the Partners to replace such other duties and liabilities of such General Partner.

37

Section 7.9    Other Matters Concerning the General Partner.

A.     The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties.

B.     The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers, architects, engineers, environmental consultants and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion of such Persons as to matters that the General Partner reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

C.     The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers and a duly appointed attorney or attorneys-in-fact. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform all and every act and duty that is permitted or required to be done by the General Partner hereunder.

D.     Notwithstanding any other provision of this Agreement or the Act, any action of the General Partner on behalf of the Partnership or any decision of the General Partner to refrain from acting on behalf of the Partnership, undertaken in the good faith belief that such action or omission is necessary or advisable in order (i) to protect the ability of the Previous Generaleach Special Limited Partner to continue to qualify as a REIT, (ii) for the Previous Generaleach Special Limited Partner otherwise to satisfy the REIT Requirements, (iii) to avoid the Previous General PartnerSpecial Limited Partners incurring any taxes under Code Section 857 or Code Section 4981 or (iv) for the General Partner or theany wholly owned subsidiary of a Special Limited Partner, as the case may be, to continue to qualify as a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)), is expressly authorized under this Agreement and is deemed approved by all of the Limited Partners.

Section 7.10    Title to Partnership Assets. Title to Partnership assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner, individually or collectively with other Partners or Persons, shall have any ownership interest in such Partnership assets or any portion thereof. Title to any or all of the Partnership assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine, including Affiliates of the General Partner. The General Partner hereby declares and warrants that any Partnership assets for which legal title is held in the name of the General Partner or any nominee or Affiliate of the General Partner shall be held by the General Partner for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use its best efforts to cause beneficial and record title to such assets to be vested in the Partnership as soon as reasonably practicable. All Partnership assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which legal title to such Partnership assets is held.

Section 7.11    Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner has full power and authority, without the consent or approval of any other Partner or Person, to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any contracts on behalf of the Partnership, and take any and all actions on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner as if it were the Partnership’s sole party in interest, both legally and beneficially. Each Limited Partner hereby waives any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of the General Partner in connection with any such dealing. In no event shall any Person

38

dealing with the General Partner or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expediency of any act or action of the General Partner or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.

ARTICLE 8

RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS

Section 8.1    Limitation of Liability. The Limited Partners shall have no liability under this Agreement except as expressly provided in this Agreement (including, without limitation, Section 10.5 hereof) or under the Act.

Section 8.2    Management of Business. No Limited Partner or Assignee (other than the General Partner, any of its Affiliates or any officer, director, member, employee, partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such) shall take part in the operations, management or control (within the meaning of the Act) of the Partnership’s business, transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the Partnership. The transaction of any such business by the General Partner, any of its Affiliates or any officer, director, member, employee, partner, agent, representative, or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such, shall not affect, impair or eliminate the limitations on the liability of the Limited Partners or Assignees under this Agreement.

Section 8.3    Outside Activities of Limited Partners. Subject to any agreements entered into pursuant to Section 7.6D hereof and any other agreements entered into by a Limited Partner or its Affiliates with the General Partner, the Partnership or a Subsidiary (including, without limitation, any employment agreement), any Limited Partner and any Assignee, officer, director, employee, agent, trustee, Affiliate or shareholder of any Limited Partner shall be entitled to and may have business interests and engage in business activities in addition to those relating to the Partnership, including business interests and activities that are in direct or indirect competition with the Partnership or that are enhanced by the activities of the Partnership. Neither the Partnership nor any Partners shall have any rights by virtue of this Agreement in any business ventures of any Limited Partner or Assignee. Subject to such agreements, none of the Limited Partners nor any other Person shall have any rights by virtue of this Agreement or the partnership relationship established hereby in any business ventures of any other Person (other than the General Partner, to the extent expressly provided herein), and such Person shall have no obligation pursuant to this Agreement, subject to Section 7.6D hereof and any other agreements entered into by a Limited Partner or its Affiliates with the General Partner, the Partnership or a Subsidiary, to offer any interest in any such business ventures to the Partnership, any Limited Partner or any such other Person, even if such opportunity is of a character that, if presented to the Partnership, any Limited Partner or such other Person, could be taken by such Person.

Section 8.4    Return of Capital. Except pursuant to the rights of Redemption set forth in Section 8.6 hereof, no Limited Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent of distributions made pursuant to this Agreement or upon termination of the Partnership as provided herein.

39

Section 8.5    Rights of Limited Partners Relating to the Partnership.

A.     In addition to other rights provided by this Agreement or by the Act, and except as limited by Section 8.5C hereof, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership, upon written demand with a statement of the purpose of such demand and at such Limited Partner’s own expense:

(1)    to obtain a copy of (i) the most recent annual and quarterly reports filed with the SEC by the Previous General Partner or the General Partner pursuant to the Exchange Act and (ii) each report or other written communication sent to the shareholders of the Previous General Partner;

(2)    to obtain a copy of the Partnership’s federal, state and local income tax returns for each Fiscal Year;

(3)    to obtain a current list of the name and last known business, residence or mailing address of each Partner;

(4)    to obtain a copy of this Agreement and the Certificate and all amendments thereto, together with executed copies of all powers of attorney pursuant to which this Agreement, the Certificate and all amendments thereto have been executed; and

(5)    to obtain true and full information regarding the amount of cash and a description and statement of any other property or services contributed by each Partner and that each Partner has agreed to contribute in the future, and the date on which each became a Partner.

B.     The Partnership shall notify any Limited Partner that is a Qualifying Party, on request, of the then current Adjustment Factor or any change made to the Adjustment Factor.

C.     Notwithstanding any other provision of this Section 8.5, the General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole and absolute discretion to be reasonable, any information that (i) the General Partner believes to be in the nature of trade secrets or other information the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or the General Partner or (ii) the Partnership or the General Partner is required by law or by agreements with unaffiliated third parties to keep confidential.

Section 8.6    Redemption Rights of Qualifying Parties.

A.     After the first Twelve-Month Period, a Qualifying Party, but no other Limited Partner or Assignee, shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Redeemable Units held by such Tendering Party (such Redeemable Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for REIT Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”). A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the Partnership Record Date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem Tendered Units for cash, the Cash Amount shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

B.     If the Partnership elects to redeem Tendered Units for REIT Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such REIT Shares to the Tendering Party pursuant to the terms set forth in this Section 8.6B, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering

40

Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for REIT Shares. The percentage of the Tendered Units tendered for Redemption by the Tendering Party for which the Partnership elects to cause the Previous General Partner to issue REIT Shares (rather than cash) is referred to as the “Applicable Percentage.” In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Qualifying Parties over another nor discriminates against a group or class of Qualifying Parties. If the Partnership elects to redeem any number of Tendered Units for REIT Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of REIT Shares equal to the product of the REIT Shares Amount and the Applicable Percentage. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The product of the Applicable Percentage and the REIT Shares Amount, if applicable, shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible REIT Shares and, if applicable, Rights, free of any pledge, lien, encumbrance or restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 8.6B, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such REIT Shares are issued pursuant to this Section 8.6B, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such REIT Shares and Rights for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. REIT Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 8.6B may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

C.     Notwithstanding the provisions of Section 8.6A and 8.6B hereof, the Tendering Parties (i) where the Redemption would consist of less than all the Partnership Common Units held by Partners other than the General Partner and the Special Limited PartnerPartners, shall not be entitled to elect or effect a Redemption to the extent that the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners) would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under this Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 8.6C, it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner under Section 8.6B hereof.

D.     In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for REIT Shares pursuant to Section 8.6B hereof following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Partner on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of REIT Shares

41

(“Registrable Shares”) equal to the REIT Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding a Partnership Interest (or an interest therein) and having Redemption rights pursuant to this Section 8.6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Partnership Common Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Partnership Common Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 8.6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the current Twelve-Month Period; provided, however, that the Previous General Partner shall not be required to acquire Partnership Common Units pursuant to this Section 8.6D more than twice within a Twelve-Month Period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

E.     Notwithstanding the provisions of Section 8.6B hereof, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for the REIT Shares Amount if such exchange would be prohibited under the Charter.

F.     Notwithstanding anything herein to the contrary (but subject to Section 8.6C hereof), with respect to any Redemption pursuant to this Section 8.6:

(1)    All Partnership Common Units acquired by the Previous General Partner pursuant to Section 8.6B hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Partnership Common Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of the same number of Partnership Common Units. Any Partnership Common Units so contributed to the Special Limited PartnerPartners shall remain outstanding.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Redeemable Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Redeemable Units, all of the Redeemable Units held by such Tendering Party.

(3)    Each Tendering Party (a) may effect a Redemption only once in each fiscal quarter of a Twelve-Month Period and (b) may not effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to Section 8.6B hereof, in the

42

event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 8.6E hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 hereof) all Redeemable Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Redeemable Units for all purposes of this Agreement, until such Redeemable Units are either paid for by the Partnership pursuant to Section 8.6A hereof or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the REIT Shares, pursuant to Section 8.6B hereof on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to Section 8.6B hereof, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 8.6F, all Partnership Common Units beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

G.     In connection with an exercise of Redemption rights pursuant to this Section 8.6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of REIT Shares by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 8.6G(1) or (b) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares in violation of the Ownership Limit.

Section 8.7    Partnership Right to Call Limited Partner Interests. Notwithstanding any other provision of this Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners ) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a

43

Tendering Party who has delivered a Notice of Redemption pursuant to Section 8.6 hereof for the amount of Partnership Common Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 8.7. Such notice given by the General Partner to a Limited Partner pursuant to this Section 8.7 shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 8.7, (a) any Limited Partner (whether or not otherwise a Qualifying Party) may, in the General Partner’s sole and absolute discretion, be treated as a Qualifying Party that is a Tendering Party and (b) the provisions of Sections 8.6C(i), 8.6F(2), 8.6F(3) and 8.6F(5) hereof shall not apply, but the remainder of Section 8.6 hereof shall apply, mutatis mutandis.

ARTICLE 9

BOOKS, RECORDS, ACCOUNTING AND REPORTS

Section 9.1    Records and Accounting.

A.     The General Partner shall keep or cause to be kept at the principal office of the Partnership those records and documents required to be maintained by the Act and other books and records deemed by the General Partner to be appropriate with respect to the Partnership’s business, including, without limitation, all books and records necessary to provide to the Limited Partners any information, lists and copies of documents required to be provided pursuant to Section 8.5A or Section 9.3 hereof. Any records maintained by or on behalf of the Partnership in the regular course of its business may be kept on, or be in the form for, punch cards, magnetic tape, photographs, micrographics or any other information storage device, provided that the records so maintained are convertible into clearly legible written form within a reasonable period of time.

B.     The books of the Partnership shall be maintained, for financial and tax reporting purposes, on an accrual basis in accordance with generally accepted accounting principles, or on such other basis as the General Partner determines to be necessary or appropriate. To the extent permitted by sound accounting practices and principles, the Partnership, the General Partner and the Previous General Partner may operate with integrated or consolidated accounting records, operations and principles.

Section 9.2    Fiscal Year. The Fiscal Year of the Partnership shall be the calendar year.

Section 9.3    Reports.

A.     As soon as practicable, but in no event later than one hundred five (105) days after the close of each Fiscal Year, the General Partner shall cause to be made available to each Limited Partner, of record as of the close of the Fiscal Year, an annual report containing financial statements of the Partnership, or of the Previous General Partner if such statements are prepared solely on a consolidated basis with the Previous General Partner, for such Fiscal Year, presented in accordance with generally accepted accounting principles, such statements to be audited by a nationally recognized firm of independent public accountants selected by the General Partner. Such report shall be deemed to be made available to all Limited Partners if it has been filed with the SEC.

B.     As soon as practicable, but in no event later than one hundred five (105) days after the close of each calendar quarter (except the last calendar quarter of each year), the General Partner shall cause to be made available to each Limited Partner, of record as of the last day of the calendar quarter, a report containing unaudited financial statements of the Partnership, or of the Previous General Partner if such statements are prepared solely on a consolidated basis with the Previous General Partner, and such other information as may be required by applicable law or regulation or as the General Partner determines to be appropriate. At the request of any Limited Partner, the General Partner shall provide access to the books, records and workpapers upon which the reports required by this Section 9.3 are based, to the extent required by the Act. Such report shall be deemed to be made available to all Limited Partners if it has been filed with the SEC.

ARTICLE 10

TAX MATTERS

Section 10.1    Preparation of Tax Returns. The General Partner shall arrange for the preparation and timely filing of all returns with respect to Partnership income, gains, deductions, losses and other items required of the Partnership for federal and state income tax purposes and shall use all reasonable effort to furnish, within ninety (90) days of the close of each taxable year, the tax information reasonably required by Limited Partners for federal and state income tax reporting purposes. The Limited Partners shall promptly provide the General Partner with such information relating to the Contributed Properties, including tax basis and other relevant information, as may be reasonably requested by the General Partner from time to time.

Section 10.2    Tax Elections.

A.     Except as otherwise provided herein, the General Partner shall, in its sole and absolute discretion, determine whether to make any available election pursuant to the Code, including, but not limited to, the election under Code Section 754 and the election to use the “recurring item” method of accounting provided under Code Section 461(h) with respect to property taxes imposed on the Partnership’s Properties; provided, however, that, if the “recurring item” method of accounting is elected with respect to such property taxes, the Partnership shall pay the applicable property taxes prior to the date provided in Code Section 461(h) for purposes of determining economic performance. The General Partner shall have the right to seek to revoke any such election (including, without limitation, any election under Code Sections 461(h) and 754) upon the General Partner’s determination in its sole and absolute discretion that such revocation is in the best interests of the Partners.

B.     The General Partner is expressly authorized to make any elections, including applicable safe harbor elections, in connection with the issuance of Partnership Interests for services that it deems to be in the best interest of the Partnership. Furthermore, the General Partner is authorized to amend this Agreement as it deems necessary to provide that (1) the Partnership is authorized and directed to elect applicable safe harbor elections, and (2) the Partnership and each of its Partners (including any person to whom a Partnership Interest is transferred in connection with the performance of services) agrees to comply with all requirements of the safe harbor with respect to all Partnership Interests transferred in connection with the performance of services while the election remains effective. Finally, the amendments relating to the safe harbor elections in connection with the issuance of Partnership Interests for services are legally binding on all Partners of the Partnership, and to the extent that it is determined that such amendments are not legally binding on all Partners, then each Partner in the Partnership that transfers a Partnership Interest in connection with the performance of services agrees to execute a document containing provisions that are legally binding on that Partner stating that (X) the Partnership is authorized and directed to elect the safe harbor, and (Y) the Partner agrees to comply with all requirements of the safe harbor with respect to all Partnership Interests transferred in connection with the performance of services while the election remains effective.

Section 10.3    Tax Matters Partner.

A.     The General Partner is hereby designated as the “tax matters partner” of the Partnership, as such term is defined in Section 6231 of the TEFRA Rules with respect to all taxable years to which the TEFRA Rules apply (the “Tax Matters Partner”). The Tax Matters Partner shall receive no compensation for its services. All third-party costs and expenses incurred by the Tax Matters Partner in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Partnership in addition to any reimbursement pursuant to Section 7.4 hereof. Nothing herein shall be construed to restrict the Partnership from engaging an accounting firm to assist the Tax Matters Partner in discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable. At the request of any Limited Partner, the General Partner agrees to consult with such Limited Partner with respect to the preparation and filing of any returns and with respect to any subsequent audit or litigation relating to such returns; provided, however, that the filing of such returns shall be in the sole and absolute discretion of the General Partner.

45

B.     The Tax Matters Partner is authorized, but not required:

(1)    to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Partnership items required to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the settlement agreement the Tax Matters Partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner (i) who (within the time prescribed pursuant to the Code and Regulations) files a statement with the IRS providing that the Tax Matters Partner shall not have the authority to enter into a settlement agreement on behalf of such Partner or (ii) who is a “notice partner” (as defined in Code Section 6231) or a member of a “notice group” (as defined in Code Section 6223(b)(2));

(2)    in the event that a notice of a final administrative adjustment at the Partnership level of any item required to be taken into account by a Partner for tax purposes (a “final adjustment”) is mailed to the Tax Matters Partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the United States Tax Court or the United States Claims Court, or the filing of a complaint for refund with the District Court of the United States for the district in which the Partnership’s principal place of business is located;

(3)    to intervene in any action brought by any other Partner for judicial review of a final adjustment;

(4)    to file a request for an administrative adjustment with the IRS at any time and, if any part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

(5)    to enter into an agreement with the IRS to extend the period for assessing any tax that is attributable to any item required to be taken into account by a Partner for tax purposes, or an item affected by such item; and

(6)    to take any other action on behalf of the Partners in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

The taking of any action and the incurring of any expense by the Tax Matters Partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the Tax Matters Partner and the provisions relating to indemnification of the General Partner set forth in Section 7.7 hereof shall be fully applicable to the Tax Matters Partner in its capacity as such. The provisions of this Section 10.3 are not applicable to any taxable years subject to the Partnership Audit Rules.

Section 10.4    Partnership Representative.

A.     The General Partner is hereby designated to serve as the “partnership representative” with respect to the Partnership, as provided in Section 6223(a) of the Partnership Audit Rules (the “Partnership Representative”). For each taxable year in which the Partnership Representative is an entity, the Partnership shall appoint the “designated individual” identified by the Partnership Representative to act on behalf of the Partnership Representative in accordance with the applicable Treasury Regulations (the “Designated Individual”). Each Partner expressly consents to such designations and agrees that it will execute, acknowledge, deliver, file and record at the appropriate public offices such documents as may be necessary or appropriate to evidence such consent.

B.     The Partnership Representative shall have the sole authority to act on behalf of the Partnership in connection with and make all relevant decisions regarding application of the Partnership Audit Rules, including, but not limited to, any elections under the Partnership Audit Rules or any decisions to settle, compromise, challenge, litigate or otherwise alter the defense of any proceeding before the IRS.

46

C.     The Partners agree to cooperate in good faith to timely provide information requested by the Partnership Representative as needed to comply with the Partnership Audit Rules, including, without limitation, to make any elections available to the Partnership under the Partnership Audit Rules. Each Partner agrees that, upon request of the Partnership, such Partner shall take such actions as may be necessary or desirable (as determined by the Partnership Representative) to (i) allow the Partnership to comply with the provisions of Section 6226 of the Partnership Audit Rules so that any “partnership adjustments” (as defined in Section 6241(2) of the Partnership Audit Rules) are taken into account by the Partners and former Partners rather than the Partnership; (ii) use the provisions of Section 6225(c) of the Partnership Audit Rules including, but not limited to, filing amended tax returns with respect to any “reviewed year” (within the meaning of Section 6225(d)(1) of the Partnership Audit Rules) or using the alternative procedure to filing amended returns to reduce the amount of any partnership adjustment otherwise required to be taken into account by the Partnership or (iii) otherwise allow the Partnership and its Partners to address and respond to any matters arising under the Partnership Audit Rules.

D.     Notwithstanding other provisions of this Agreement to the contrary, if any partnership adjustment is determined with respect to the Partnership, the Partnership Representative may cause the Partnership to elect pursuant to Section 6226 of the Partnership Audit Rules to have such adjustment passed through to the Partners for the year to which the adjustment relates (i.e., the “reviewed year” within the meaning of Section 6225(d)(1) of the Partnership Audit Rules). In the event that the Partnership Representative has not caused the Partnership to so elect pursuant to Section 6226 of the Partnership Audit Rules, then any “imputed underpayment” (as determined in accordance with Section 6225 of the Partnership Audit Rules) or partnership adjustment that does not give rise to an “imputed underpayment” shall be apportioned among the Partners of the Partnership for the taxable year in which the adjustment is finalized in such manner as may be necessary (as determined by the Partnership Representative in good faith) so that, to the maximum extent possible, the tax and economic consequences of the imputed underpayment or other partnership adjustment and any associated interest and penalties (any such amount, an “Imputed Underpayment Amount”) are borne by the Partners based upon their interests in the Partnership for the reviewed year. Imputed Underpayment Amounts also shall include any imputed underpayment within the meaning of Section 6225 of the Partnership Audit Rules paid (or payable) by any entity treated as a partnership for U.S. federal income tax purposes in which the Partnership holds (or has held) a direct or indirect interest other than through entities treated as corporations for U.S. federal income tax purposes to the extent that the Partnership bears the economic burden of such amounts, whether by law or contract.

E.     Each Partner agrees to indemnify and hold harmless the Partnership from and against any liability with respect to such Partner’s share of any tax deficiency paid or payable by the Partnership that is allocable to the Partner as determined in accordance with the second to last sentence of paragraph D above with respect to an audited or reviewed taxable year for which such Partner was a partner in the Partnership. The obligations set forth in this paragraph E shall survive the termination of any Partner’s interest in the Partnership, the termination of this Agreement and/or the termination, dissolution, liquidation or winding up of the Partnership, and shall remain binding on each Partner for the period of time necessary to resolve with the IRS (or any other applicable taxing authority) all income tax matters relating to the Partnership and for Partners to satisfy their indemnification obligations, if any, pursuant to this Section 10.4. Any obligation of a Partner pursuant to this paragraph E shall be implemented through adjustments to distributions otherwise payable to such Partner as determined in accordance with Article 5; provided, however, that, at the written request of the Partnership Representative, each Partner or former Partner may be required to contribute to the Partnership such Partner’s Imputed Underpayment Amount imposed on and paid by the Partnership; provided further, that if a Partner or former Partner individually directly pays, pursuant to the Partnership Audit Rules, any such Imputed Underpayment Amount, then such payment shall reduce any offset to distribution or required capital contribution of such Partner or former Partner. Any amount withheld from distributions pursuant to this paragraph E shall be treated as an amount distributed to such Partner or former Partner for all purposes under this Agreement.

F.     All expenses incurred by the Partnership Representative or Designated Individual in connection with its duties as partnership representative or designated individual, as applicable, shall be expenses of the

47

Partnership (including, for the avoidance of doubt, any costs and expenses incurred in connection with any claims asserted against the Partnership Representative or Designated Individual, as applicable, except, in the case of the Partnership Representative, to the extent the Partnership Representative is determined to have performed its duties in the manner described in the final sentence of this paragraph F, and the Partnership shall reimburse the Partnership Representative or Designated Individual, as applicable, for all such costs and expenses). Nothing herein shall be construed to restrict the Partnership Representative or Designated Individual from engaging lawyers, accountants, tax advisers, or other professional advisers or experts to assist the Partnership Representative or Designated Individual in discharging its duties hereunder. Neither the Partnership Representative nor the Designated Individual shall be liable to the Partnership, any Partner or any Affiliate thereof for any costs or losses to any persons, any diminution in value or any liability whatsoever arising as a result of the performance of its duties pursuant to this Section 10.4; provided, however, that the Partnership Representative may be so liable if it or the Designated Individual has engaged in (i) willful breach of any provision of this Section 10.4 or (ii) fraud, willful misconduct or gross negligence, in each case, with respect to its performance of its duties pursuant to this Section 10.4.

Section 10.5    Withholding for Taxes, Etc.

A.     Withholding. Each Limited Partner hereby authorizes the Partnership to withhold from such Limited Partner any amount of federal, state, local or foreign taxes that the General Partner determines, in its sole discretion, that the Partnership is, or may in the future be, required to withhold or pay with respect to any amount distributable, allocable or payable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Partnership pursuant to Code Section 1441, Code Section 1442, Code Section 1445 or Code Section 1446. Amounts withheld by the General Partner may be estimated by the General Partner, in its sole discretion, based on its expectations of future transactions involving the Partnership that may give rise to taxes of such Limited Partner. The General Partner may withhold amounts for taxes (including estimated or projected taxes) from cash or other distributions otherwise payable to a Limited Partner, or from any REIT Shares or Cash Amount otherwise payable to a Limited Partner in connection with a Redemption.

B.     Certain Tax Payments. Each Limited Partner hereby authorizes the Partnership to pay on behalf of or with respect to such Limited Partner any amount of federal, state, local or foreign taxes that the General Partner determines, in its sole discretion, that the Partnership is required to pay with respect to any amount distributable, allocable or payable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be paid by the Partnership pursuant to Code Section 1441, Code Section 1442, Code Section 1445 or Code Section 1446. Any amount paid on behalf of or with respect to a Limited Partner shall constitute a loan by the Partnership to such Limited Partner, which loan shall be repaid by such Limited Partner within fifteen (15) days after notice from the General Partner that such payment must be made unless (i) the Partnership withholds such payment from a distribution that would otherwise be made to the Limited Partner or (ii) the General Partner determines, in its sole and absolute discretion, that such payment may be satisfied out of the Available Funds of the Partnership that would, but for such payment, be distributed to the Limited Partner. Each Limited Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Limited Partner’s Partnership Interest to secure such Limited Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 10.5B. In the event that a Limited Partner fails to pay any amounts owed to the Partnership pursuant to this Section 10.5B within fifteen (15) days after the notice from the General Partner specified above, then the General Partner may, in its sole and absolute discretion, either (x) elect to make the payment to the Partnership on behalf of such defaulting Limited Partner, and in such event shall be deemed to have loaned such amount to such defaulting Limited Partner and shall succeed to all rights and remedies of the Partnership as against such defaulting Limited Partner (including, without limitation, the right to receive distributions), or (y) cause the Partnership to redeem from such Limited Partner a number of Partnership Common Units (or fraction thereof) equal to the quotient obtained by dividing (i) the aggregate amount owed by such Limited Partner to the Partnership pursuant to this Section 10.5B, by (ii) the product of (1) the Adjustment Factor in effect as of date of redemption specified by the General Partner, and (2) the Value

48

of a REIT Share (assuming for such purpose that the Valuation Date is the date of redemption specified by the General Partner). If the General Partner elects to cause the Partnership to redeem any Limited Partner’s Partnership Common Units pursuant to clause (y) above, it shall promptly so notify such Limited Partner in writing of the date of such redemption and the number of Partnership Common Units so redeemed. Any amounts payable by a Limited Partner under this Section 10.5B shall bear interest at the base rate on corporate loans at large United States money center commercial banks, as published from time to time in the Wall Street Journal, plus four (4) percentage points (but not higher than the maximum lawful rate) from the date such amount is due (i.e., fifteen (15) days after demand) until such amount is paid in full. Each Limited Partner shall take such actions as the Partnership or the General Partner shall request in order to perfect or enforce the security interest created hereunder, or to assist the Partnership in effecting any redemption of such Limited Partner’s Partnership Common Units as specified in clause (y) above.

ARTICLE 11

TRANSFERS AND WITHDRAWALS

Section 11.1    Transfer.

A.     No part of the interest of a Partner shall be subject to the claims of any creditor, to any spouse for alimony or support, or to legal process, and may not be voluntarily or involuntarily alienated or encumbered except as may be specifically provided for in this Agreement.

B.     No Partnership Interest shall be Transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article 11. Any Transfer or purported Transfer of a Partnership Interest not made in accordance with this Article 11 shall be null and void ab initio.

C.     Notwithstanding the other provisions of this Article 11 (other than Section 11.6D hereof), the Partnership Interests of the General Partner and the Special Limited PartnerPartners may be Transferred, in whole or in part, at any time or from time to time, to or among the Previous General Partner, theGeneral Partner, the Special Limited PartnerPartners, and any other Person that is, at the time of such Transfer, a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) with respect to the Previous Generalany Special Limited Partner. Any transferee of the entire General Partner Interest pursuant to this Section 11.1C shall automatically become, without further action or Consent of any Limited Partners, the sole general partner of the Partnership, subject to all the rights, privileges, duties and obligations under this Agreement and the Act relating to a general partner. Any transferee of a Limited Partner Interest pursuant to this Section 11.1C shall automatically become, without further action or Consent of any Limited Partners, a Substituted Limited Partner. Upon any Transfer permitted by this Section 11.1C, the transferor Partner shall be relieved of all its obligations under this Agreement. The provisions of Section 11.2B (other than the last sentence thereof), 11.3, 11.4A and 11.5 hereof shall not apply to any Transfer permitted by this Section 11.1C.

Section 11.2    Transfer of General Partner’s Partnership Interest.

A.     The General Partner may not Transfer any of its General Partner Interest or withdraw from the Partnership except as provided in Sections 11.2B and 11.2C hereof.

B.     The General Partner shall not withdraw from the Partnership and shall not Transfer all or any portion of its interest in the Partnership (whether by sale, disposition, statutory merger or consolidation, liquidation or otherwise) without the Consent of the Limited Partners, which Consent may be given or withheld in the sole and absolute discretion of the Limited Partners. Upon any Transfer of such a Partnership Interest pursuant to the Consent of the Limited Partners and otherwise in accordance with the provisions of this Section 11.2B, the transferee shall become a successor General Partner for all purposes herein, and shall be

49

vested with the powers and rights of the transferor General Partner, and shall be liable for all obligations and responsible for all duties of the General Partner, once such transferee has executed such instruments as may be necessary to effectuate such admission and to confirm the agreement of such transferee to be bound by all the terms and provisions of this Agreement with respect to the Partnership Interest so acquired. It is a condition to any Transfer otherwise permitted hereunder that the transferee assumes, by operation of law or express agreement, all of the obligations of the transferor General Partner under this Agreement with respect to such Transferred Partnership Interest, and such Transfer shall relieve the transferor General Partner of its obligations under this Agreement without the Consent of the Limited Partners. In the event that the General Partner withdraws from the Partnership, in violation of this Agreement or otherwise, or otherwise dissolves or terminates, or upon the bankruptcy of the General Partner, a Majority in Interest of the Limited Partners may elect to continue the Partnership business by selecting a successor General Partner in accordance with the Act.

C.     The General Partner may merge with another entity if immediately after such merger substantially all of the assets of the surviving entity, other than the General Partner Interest held by the General Partner, are contributed to the Partnership as a Capital Contribution in exchange for Partnership Units.

Section 11.3    Limited Partners’ Rights to Transfer.

A.     General. Prior to the end of the first Twelve-Month Period, no Limited Partner shall Transfer all or any portion of its Partnership Interest to any transferee without the Consent of the General Partner, which Consent may be withheld in its sole and absolute discretion; provided, however, that any Limited Partner may, at any time, without the consent of the General Partner, (i) Transfer all or part of its Partnership Interest to any Designated Party, any Family Member, any Controlled Entity or any Affiliate, provided that the transferee is, in any such case, a Qualified Transferee, or (ii) pledge (a “Pledge”) all or any portion of its Partnership Interest to a lending institution, that is not an Affiliate of such Limited Partner, as collateral or security for a bona fide loan or other extension of credit, and Transfer such pledged Partnership Interest to such lending institution in connection with the exercise of remedies under such loan or extension or credit (any Transfer or Pledge permitted by this proviso is hereinafter referred to as a “Permitted Transfer”). After such first Twelve-Month Period, each Limited Partner, and each transferee of Partnership Units or Assignee pursuant to a Permitted Transfer, shall have the right to Transfer all or any portion of its Partnership Interest to any Person, subject to the provisions of Section 11.6 hereof and to satisfaction of each of the following conditions:

(1)    General Partner Right of First Refusal. The transferring Partner shall give written notice of the proposed Transfer to the General Partner, which notice shall state (i) the identity of the proposed transferee and (ii) the amount and type of consideration proposed to be received for the Transferred Partnership Units. The General Partner shall have ten (10) Business Days upon which to give the Transferring Partner notice of its election to acquire the Partnership Units on the proposed terms. If it so elects, it shall purchase the Partnership Units on such terms within ten (10) Business Days after giving notice of such election; provided, however, that in the event that the proposed terms involve a purchase for cash, the General Partner may at its election deliver in lieu of all or any portion of such cash a note payable to the Transferring Partner at a date as soon as reasonably practicable, but in no event later than one hundred eighty (180) days after such purchase, and bearing interest at an annual rate equal to the total dividends declared with respect to one (1) REIT Share for the four (4) preceding fiscal quarters of the General Partner, divided by the Value as of the closing of such purchase; provided, further, that such closing may be deferred to the extent necessary to effect compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, and any other applicable requirements of law. If it does not so elect, the Transferring Partner may Transfer such Partnership Units to a third party, on terms no more favorable to the transferee than the proposed terms, subject to the other conditions of this Section 11.3.

(2)    Qualified Transferee. Any Transfer of a Partnership Interest shall be made only to a single Qualified Transferee; provided, however, that, for such purposes, all Qualified Transferees that are Affiliates, or that comprise investment accounts or funds managed by a single Qualified Transferee and

50

its Affiliates, shall be considered together to be a single Qualified Transferee; provided, further, that each Transfer meeting the minimum Transfer restriction of Section 11.3A(3) hereof may be to a separate Qualified Transferee.

(3)    Minimum Transfer Restriction. Any Transferring Partner must Transfer not less than the lesser of (i) the greater of five hundred (500) Partnership Units or one-third (1/3) of the number of Partnership Units owned by such Partner as of the Effective Date or (ii) all of the remaining Partnership Units owned by such Transferring Partner; provided, however, that, for purposes of determining compliance with the foregoing restriction, all Partnership Units owned by Affiliates of a Limited Partner shall be considered to be owned by such Limited Partner.

(4)    Transferee Agreement to Effect a Redemption. Any proposed transferee shall deliver to the General Partner a written agreement reasonably satisfactory to the General Partner to the effect that the transferee will, within six (6) months after consummation of a Partnership Common Units Transfer, tender its Partnership Common Units for Redemption in accordance with the terms of the Redemption rights provided in Section 8.6 hereof.

(5)    No Further Transfers. The transferee (other than a Designated Party) shall not be permitted to effect any further Transfer of the Partnership Units, other than to the General Partner.

(6)    Exception for Permitted Transfers. The conditions of Sections 11.3A(1) through 11.3A(5) hereof shall not apply in the case of a Permitted Transfer.

It is a condition to any Transfer otherwise permitted hereunder (whether or not such Transfer is effected during or after the first Twelve-Month Period) that the transferee assumes by operation of law or express agreement all of the obligations of the transferor Limited Partner under this Agreement with respect to such Transferred Partnership Interest, and no such Transfer (other than pursuant to a statutory merger or consolidation wherein all obligations and liabilities of the transferor Partner are assumed by a successor corporation by operation of law) shall relieve the transferor Partner of its obligations under this Agreement without the approval of the General Partner, in its sole and absolute discretion. Notwithstanding the foregoing, any transferee of any Transferred Partnership Interest shall be subject to any and all ownership limitations (including, without limitation, the Ownership Limit) contained in the Charter that may limit or restrict such transferee’s ability to exercise its Redemption rights, including, without limitation, the Ownership Limit. Any transferee, whether or not admitted as a Substituted Limited Partner, shall take subject to the obligations of the transferor hereunder. Unless admitted as a Substituted Limited Partner, no transferee, whether by a voluntary Transfer, by operation of law or otherwise, shall have any rights hereunder, other than the rights of an Assignee as provided in Section 11.5 hereof.

B.     Incapacity. If a Limited Partner is subject to Incapacity, the executor, administrator, trustee, committee, guardian, conservator or receiver of such Limited Partner’s estate shall have all the rights of a Limited Partner, but not more rights than those enjoyed by other Limited Partners, for the purpose of settling or managing the estate, and such power as the Incapacitated Limited Partner possessed to Transfer all or any part of its interest in the Partnership. The Incapacity of a Limited Partner, in and of itself, shall not dissolve or terminate the Partnership.

C.     Opinion of Counsel. In connection with any Transfer of a Limited Partner Interest, the General Partner shall have the right to receive an opinion of counsel reasonably satisfactory to it to the effect that the proposed Transfer may be effected without registration under the Securities Act and will not otherwise violate any federal or state securities laws or regulations applicable to the Partnership or the Partnership Interests Transferred. If, in the opinion of such counsel, such Transfer would require the filing of a registration statement under the Securities Act or would otherwise violate any federal or state securities laws or regulations applicable to the Partnership or the Partnership Units, the General Partner may prohibit any Transfer otherwise permitted under this Section 11.3 by a Limited Partner of Partnership Interests.

51

D.     Adverse Tax Consequences. No Transfer by a Limited Partner of its Partnership Interests (including any Redemption, any other acquisition of Partnership Units by the General Partner or any acquisition of Partnership Units by the Partnership) may be made to any person if (i) in the opinion of legal counsel for the Partnership, it would result in the Partnership being treated as an association taxable as a corporation, or (ii) such Transfer is effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Code Section 7704. Upon any Transfer by a Limited Partner of its Partnership Interests, such Limited Partner shall (a) provide the Partnership and the transferee receiving such an interest an affidavit satisfying the requirements of Section 1446(f)(2) of the Code stating, under penalty of perjury, (i) the transferor Limited Partner’s United States taxpayer identification number and (ii) that such Limited Partner is not a “foreign person” within the meaning of Code Section 1446, and (b) provide the Partnership with such other information and assistance as the Partnership may request to ensure that the Company is not subject to withholding under Section 1446 of the Code.

Section 11.4    Substituted Limited Partners.

A.     No Limited Partner shall have the right to substitute a transferee (including any Designated Party or other transferees pursuant to Transfers permitted by Section 11.3 hereof) as a Limited Partner in its place. A transferee (including, but not limited to, any Designated Party) of the interest of a Limited Partner may be admitted as a Substituted Limited Partner only with the Consent of the General Partner, which Consent may be given or withheld by the General Partner in its sole and absolute discretion. The failure or refusal by the General Partner to permit a transferee of any such interests to become a Substituted Limited Partner shall not give rise to any cause of action against the Partnership or the General Partner. Subject to the foregoing, an Assignee shall not be admitted as a Substituted Limited Partner until and unless it furnishes to the General Partner (i) evidence of acceptance, in form and substance satisfactory to the General Partner, of all the terms, conditions and applicable obligations of this Agreement, (ii) a counterpart signature page to this Agreement executed by such Assignee and (iii) such other documents and instruments as may be required or advisable, in the sole and absolute discretion of the General Partner, to effect such Assignee’s admission as a Substituted Limited Partner.

B.     A transferee who has been admitted as a Substituted Limited Partner in accordance with this Article 11 shall have all the rights and powers and be subject to all the restrictions and liabilities of a Limited Partner under this Agreement.

C.     Upon the admission of a Substituted Limited Partner, the General Partner shall amend Exhibit A to reflect the name, address and number of Partnership Units of such Substituted Limited Partner and to eliminate or adjust, if necessary, the name, address and number of Partnership Units of the predecessor of such Substituted Limited Partner.

Section 11.5    Assignees. If the General Partner, in its sole and absolute discretion, does not consent to the admission of any permitted transferee under Section 11.3 hereof as a Substituted Limited Partner, as described in Section 11.4 hereof, such transferee shall be considered an Assignee for purposes of this Agreement. An Assignee shall be entitled to all the rights of an assignee of a limited partnership interest under the Act, including the right to receive distributions from the Partnership and the share of Net Income, Net Losses and other items of income, gain, loss, deduction and credit of the Partnership attributable to the Partnership Units assigned to such transferee and the rights to Transfer the Partnership Units provided in this Article 11, but shall not be deemed to be a holder of Partnership Units for any other purpose under this Agreement (other than as expressly provided in Section 8.6 hereof with respect to a Qualifying Party that becomes a Tendering Party), and shall not be entitled to effect a Consent or vote with respect to such Partnership Units on any matter presented to the Limited Partners for approval (such right to Consent or vote, to the extent provided in this Agreement or under the Act, fully remaining with the transferor Limited Partner). In the event that any such transferee desires to make a further assignment of any such Partnership Units, such transferee shall be subject to all the provisions of this Article 11 to the same extent and in the same manner as any Limited Partner desiring to make an assignment of Partnership Units.

52

Section 11.6    General Provisions.

A.     No Limited Partner may withdraw from the Partnership other than as a result of a permitted Transfer of all of such Limited Partner’s Partnership Units in accordance with this Article 11, with respect to which the transferee becomes a Substituted Limited Partner, or pursuant to a redemption (or acquisition by the Previous General Partner) of all of its Partnership Units pursuant to a Redemption under Section 8.6 hereof and/or pursuant to any Partnership Unit Designation.

B.     Any Limited Partner who shall Transfer all of its Partnership Units in a Transfer (i) permitted pursuant to this Article 11 where such transferee was admitted as a Substituted Limited Partner, (ii) pursuant to the exercise of its rights to effect a redemption of all of its Partnership Units pursuant to a Redemption under Section 8.6 hereof and/or pursuant to any Partnership Unit Designation or (iii) to the Previous General Partner or the General Partner, whether or not pursuant to Section 8.6B hereof, shall cease to be a Limited Partner.

C.     If any Partnership Unit is Transferred in compliance with the provisions of this Article 11, or is redeemed by the Partnership, or acquired by the Previous General Partner pursuant to Section 8.6 hereof, on any day other than the first day of a Fiscal Year, then Net Income, Net Loss, each item thereof and all other items of income, gain, loss, deduction and credit attributable to such Partnership Unit for such Fiscal Year shall be allocated to the transferor Partner or the Tendering Party, as the case may be, and, in the case of a Transfer or assignment other than a Redemption, to the transferee Partner (including, without limitation, the General Partner and the Special Limited PartnerPartners as transferees of the Previous General Partner in the case of an acquisition of Partnership Common Units pursuant to Section 8.6 hereof), by taking into account their varying interests during the Fiscal Year in accordance with Code Section 706(d), using the “interim closing of the books” method or another permissible method selected by the General Partner. All distributions of Available Cash attributable to such Partnership Unit with respect to which the Partnership Record Date is before the date of such Transfer, assignment or Redemption shall be made to the transferor Partner or the Tendering Party, as the case may be, and, in the case of a Transfer other than a Redemption, all distributions of Available Cash thereafter attributable to such Partnership Unit shall be made to the transferee Partner.

D.     In addition to any other restrictions on Transfer herein contained, in no event may any Transfer or assignment of a Partnership Interest by any Partner (including any Redemption, any acquisition of Partnership Units by the Previous General Partner or any other acquisition of Partnership Units by the Partnership) be made (i) to any person or entity who lacks the legal right, power or capacity to own a Partnership Interest; (ii) in violation of applicable law; (iii) of any component portion of a Partnership Interest, such as the Capital Account, or rights to distributions, separate and apart from all other components of a Partnership Interest; (iv) in the event that such Transfer would cause either (a) the Previous Generalany Special Limited Partner to cease to comply with the REIT Requirements or (b) the General Partner or theany other wholly owned subsidiary of a Special Limited Partner to cease to qualify as a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)); (v) if such Transfer would, in the opinion of counsel to the Partnership or the General Partner, cause a termination of the Partnership for federal or state income tax purposes (except as a result of the Redemption (or acquisition by the Previous General Partner) of all Partnership Common Units held by all Limited Partners other than the Special Limited PartnerPartners ); (vi) if such Transfer would, in the opinion of legal counsel to the Partnership, cause the Partnership to cease to be classified as a partnership for federal income tax purposes (except as a result of the Redemption (or acquisition by the Previous General Partner) of all Partnership Common Units held by all Limited Partners other than the Special Limited PartnerPartners ); (vii) if such Transfer would cause the Partnership to become, with respect to any employee benefit plan subject to Title I of ERISA, a “party-in-interest” (as defined in ERISA Section 3(14)) or a “disqualified person” (as defined in Code Section 4975(c)); (viii) if such Transfer would, in the opinion of legal counsel to the Partnership, cause any portion of the assets of the Partnership to constitute assets of any employee benefit plan pursuant to Department of Labor Regulations Section 2510.2-101; (ix) if such Transfer requires the registration of such Partnership Interest pursuant to any applicable federal or state securities laws; (x) if such Transfer causes the Partnership to become a “publicly traded partnership,” as such term is defined in Code Section 469(k)(2) or Code 7704(b); or

53

(xi) if such Transfer subjects the Partnership to regulation under the Investment Company Act of 1940, the Investment Advisors Act of 1940 or ERISA, each as amended.

ARTICLE 12

ADMISSION OF PARTNERS

Section 12.1    Admission of Successor General Partner. A successor to all of the General Partner’s General Partner Interest pursuant to Section 11.2 hereof who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately prior to such Transfer. Any such successor shall carry on the business of the Partnership without dissolution. In each case, the admission shall be subject to the successor General Partner executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be required to effect the admission.

Section 12.2    Admission of Additional Limited Partners.

A.     After the admission to the Partnership of an Original Limited Partner on the date hereof, a Person (other than an existing Partner) who makes a Capital Contribution to the Partnership in accordance with this Agreement shall be admitted to the Partnership as an Additional Limited Partner only upon furnishing to the General Partner (i) evidence of acceptance, in form and substance satisfactory to the General Partner, of all of the terms and conditions of this Agreement, including, without limitation, the power of attorney granted in Section 2.4 hereof, (ii) a counterpart signature page to this Agreement executed by such Person and (iii) such other documents or instruments as may be required in the sole and absolute discretion of the General Partner in order to effect such Person’s admission as an Additional Limited Partner.

B.     Notwithstanding anything to the contrary in this Section 12.2, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner’s sole and absolute discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded on the books and records of the Partnership, following the consent of the General Partner to such admission.

C.     If any Additional Limited Partner is admitted to the Partnership on any day other than the first day of a Fiscal Year, then Net Income, Net Losses, each item thereof and all other items of income, gain, loss, deduction and credit allocable among Partners and Assignees for such Fiscal Year shall be allocated among such Additional Limited Partner and all other Partners and Assignees by taking into account their varying interests during the Fiscal Year in accordance with Code Section 706(d), using the “interim closing of the books” method or another permissible method selected by the General Partner. Solely for purposes of making such allocations, each of such items for the calendar month in which an admission of any Additional Limited Partner occurs shall be allocated among all the Partners and Assignees including such Additional Limited Partner, in accordance with the principles described in Section 11.6C hereof. All distributions of Available Cash with respect to which the Partnership Record Date is before the date of such admission shall be made solely to Partners and Assignees other than the Additional Limited Partner, and all distributions of Available Cash thereafter shall be made to all the Partners and Assignees including such Additional Limited Partner.

Section 12.3    Amendment of Agreement and Certificate of Limited Partnership. For the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Act to amend the records of the Partnership and, if necessary, to prepare as soon as practical an amendment of this Agreement (including an amendment of Exhibit A) and, if required by law, shall prepare and file an amendment to the Certificate and may for this purpose exercise the power of attorney granted pursuant to Section 2.4 hereof.

54

Section 12.4    Admission of Initial Limited Partners. The Persons listed on Exhibit A as limited partners of the Partnership shall be admitted to the Partnership as Limited Partners upon their execution and delivery of this Agreement.

ARTICLE 13

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 13.1    Dissolution. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the withdrawal of the General Partner, any successor General Partner shall continue the business of the Partnership without dissolution. However, the Partnership shall dissolve, and its affairs shall be wound up, upon the first to occur of any of the following (each a “Liquidating Event”):

A.     the expiration of its term as provided in Section 2.5 hereof;

B.     an event of withdrawal, as defined in the Act (including, without limitation, bankruptcy), of the sole General Partner unless, within ninety (90) days after the withdrawal, a “majority in interest” (as such phrase is used in Section 17-801(3) of the Act) of the remaining Partners agree in writing, in their sole and absolute discretion, to continue the business of the Partnership and to the appointment, effective as of the date of withdrawal, of a successor General Partner:

C.     an election to dissolve the Partnership made by the General Partner in its sole and absolute discretion, with or without the Consent of the Limited Partners;

D.     entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Act;

E.     the occurrence of a Terminating Capital Transaction;

F.     the Redemption (or acquisition by the Previous Generala Special Limited Partner, the General Partner and/or the Special LimitedGeneral Partner) of all Partnership Common Units other than Partnership Common Units held by the General Partner or thea Special Limited Partner that holds all of the interests in the General Partner; or

G.     the Redemption (or acquisition by the General Partner) of all Partnership Common Units other than Partnership Common Units held by the General Partner.

Section 13.2    Winding Up.

A.     Upon the occurrence of a Liquidating Event, the Partnership shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets and satisfying the claims of its creditors and Partners. After the occurrence of a Liquidating Event, no Partner shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Partnership’s business and affairs. The General Partner (or, in the event that there is no remaining General Partner or the General Partner has dissolved, become bankrupt within the meaning of the Act or ceased to operate, any Person elected by a Majority in Interest of the Limited Partners (the General Partner or such other Person being referred to herein as the “Liquidator”)) shall be responsible for overseeing the winding up and dissolution of the Partnership and shall take full account of the Partnership’s liabilities and property, and the Partnership property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom (which may, to the extent determined by the

55

General Partner, include shares of stock in the Previous General Partner) shall be applied and distributed in the following order:

(1)    First, to the satisfaction of all of the Partnership’s debts and liabilities to creditors other than the Partners and their Assignees (whether by payment or the making of reasonable provision for payment thereof);

(2)    Second, to the satisfaction of all of the Partnership’s debts and liabilities to the General Partner (whether by payment or the making of reasonable provision for payment thereof), including, but not limited to, amounts due as reimbursements under Section 7.4 hereof;

(3)    Third, to the satisfaction of all of the Partnership’s debts and liabilities to the other Partners and any Assignees (whether by payment or the making of reasonable provision for payment thereof); and

(4)    Subject to the terms of any Partnership Unit Designation, the balance, if any, to the General Partner, the Limited Partners and any Assignees in accordance with and in proportion to their positive Capital Account balances, after giving effect to all contributions, distributions and allocations for all periods.

The General Partner shall not receive any additional compensation for any services performed pursuant to this Article 13.

B.     Notwithstanding the provisions of Section 13.2A hereof that require liquidation of the assets of the Partnership, but subject to the order of priorities set forth therein, if prior to or upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss to the Partners, the Liquidator may, in its sole and absolute discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Partnership (including to those Partners as creditors) and/or distribute to the Partners, in lieu of cash, as tenants in common and in accordance with the provisions of Section 13.2A hereof, undivided interests in such Partnership assets as the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be made only if, in the good faith judgment of the Liquidator, such distributions in kind are in the best interest of the Partners, and shall be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreements governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of valuation as it may adopt.

C.     In the event that the Partnership is “liquidated” within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made pursuant to this Article 13 to the Partners and Assignees that have positive Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2) to the extent of, and in proportion to, positive Capital Account balances. If any Partner has a deficit balance in its Capital Account (after giving effect to all contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), such Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and such deficit shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever. In the sole and absolute discretion of the General Partner or the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Partners pursuant to this Article 13 may be withheld or escrowed to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Partnership, provided that such withheld or escrowed amounts shall be distributed to the General Partner and Limited Partners in the manner and order of priority set forth in Section 13.2A hereof as soon as practicable.

Section 13.3    Deemed Distribution and Recontribution. Notwithstanding any other provision of this Article 13, in the event that the Partnership is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), but no Liquidating Event has occurred, the Partnership’s Property shall not be

56

liquidated, the Partnership’s liabilities shall not be paid or discharged and the Partnership’s affairs shall not be wound up. Instead, for federal income tax purposes the Partnership shall be deemed to have distributed the Property in kind to the Partners and the Assignees, who shall be deemed to have assumed and taken such Property subject to all Partnership liabilities, all in accordance with their respective Capital Accounts. Immediately thereafter, the Partners and the Assignees shall be deemed to have recontributed the Partnership Property in kind to the Partnership, which shall be deemed to have assumed and taken such Property subject to all such liabilities; provided, however, that nothing in this Section 13.3 shall be deemed to have constituted any Assignee as a Substituted Limited Partner without compliance with the provisions of Section 11.4 hereof.

Section 13.4    Rights of Limited Partners. Except as otherwise provided in this Agreement, (a) each Limited Partner shall look solely to the assets of the Partnership for the return of its Capital Contribution, (b) no Limited Partner shall have the right or power to demand or receive property other than cash from the Partnership and (c) no Limited Partner shall have priority over any other Limited Partner as to the return of its Capital Contributions, distributions or allocations.

Section 13.5    Notice of Dissolution. In the event that a Liquidating Event occurs or an event occurs that would, but for an election or objection by one or more Partners pursuant to Section 13.1 hereof, result in a dissolution of the Partnership, the General Partner shall, within thirty (30) days thereafter, provide written notice thereof to each of the Partners and, in the General Partner’s sole and absolute discretion or as required by the Act, to all other parties with whom the Partnership regularly conducts business (as determined in the sole and absolute discretion of the General Partner), and the General Partner may, or, if required by the Act, shall, publish notice thereof in a newspaper of general circulation in each place in which the Partnership regularly conducts business (as determined in the sole and absolute discretion of the General Partner).

Section 13.6    Cancellation of Certificate of Limited Partnership. Upon the completion of the liquidation of the Partnership cash and property as provided in Section 13.2 hereof, the Partnership shall be terminated, a certificate of cancellation shall be filed with the State of Delaware, all qualifications of the Partnership as a foreign limited partnership or association in jurisdictions other than the State of Delaware shall be cancelled, and such other actions as may be necessary to terminate the Partnership shall be taken.

Section 13.7    Reasonable Time for Winding-Up. A reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Section 13.2 hereof, in order to minimize any losses otherwise attendant upon such winding-up, and the provisions of this Agreement shall remain in effect between the Partners during the period of liquidation.

Following such proposal, the General Partner shall submit any proposed amendment to the Limited Partners. The General Partner shall seek the written consent of the Limited Partners on the proposed amendment or shall call a meeting to vote thereon and to transact any other business that the General Partner may deem appropriate. For purposes of obtaining a written consent, the General Partner may require a response within a reasonable specified time, but not less than fifteen (15) days, and failure to

57

respond in such time period shall constitute a consent that is consistent with the General Partner’s recommendation with respect to the proposal; provided, however, that an action shall become effective at such time as requisite consents are received even if prior to such specified time.

Section 14.3    Meetings of the Partners.

A.     Meetings of the Partners may be called by the General Partner and shall be called upon the receipt by the General Partner of a written request by a Majority in Interest of the Limited Partners. The call shall state the nature of the business to be transacted. Notice of any such meeting shall be given to all Partners not less than seven (7) days nor more than thirty (30) days prior to the date of such meeting. Partners may vote in person or by proxy at such meeting. Whenever the vote or Consent of Partners is permitted or required under this Agreement, such vote or Consent may be given at a meeting of Partners or may be given in accordance with the procedure prescribed in Section 14.3B hereof.

B.     Any action required or permitted to be taken at a meeting of the Partners may be taken without a meeting if a written consent setting forth the action so taken is signed by a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement for the action in question). Such consent may be in one instrument or in several instruments, and shall have the same force and effect as a vote of a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement). Such consent shall be filed with the General Partner. An action so taken shall be deemed to have been taken at a meeting held on the effective date so certified.

C.     Each Limited Partner may authorize any Person or Persons to act for it by proxy on all matters in which a Limited Partner is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting. Every proxy must be signed by the Limited Partner or its attorney-in-fact. No proxy shall be valid after the expiration of eleven (11) months from the date thereof unless otherwise provided in the proxy (or there is receipt of a proxy authorizing a later date). Every proxy shall be revocable at the pleasure of the Limited Partner executing it, such revocation to be effective upon the Partnership’s receipt of written notice of such revocation from the Limited Partner executing such proxy.

D.     Each meeting of Partners shall be conducted by the General Partner or such other Person as the General Partner may appoint pursuant to such rules for the conduct of the meeting as the General Partner or such other Person deems appropriate in its sole and absolute discretion. Without limitation, meetings of Partners may be conducted in the same manner as meetings of the General Partner’s shareholders and may be held at the same time as, and as part of, the meetings of the General Partner’s shareholders.

Section 15.6    Waiver.

A.     No failure by any party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such breach or any other covenant, duty, agreement or condition.

Section 15.8    Applicable Law. This Agreement shall be construed and enforced in accordance with and governed by the laws of the State of Delaware, without regard to the principles of conflicts of law. In the event of a conflict between any provision of this Agreement and any non-mandatory provision of the Act, the provisions of this Agreement shall control and take precedence.

Section 15.10    Invalidity of Provisions. If any provision of this Agreement is or becomes invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not be affected thereby.

Section 15.11    Limitation to Preserve REIT Status. Notwithstanding anything else in this Agreement, to the extent that the amount paid, credited, distributed or reimbursed by the Partnership to any REIT Partner or its officers, directors, employees or agents, whether as a reimbursement, fee, expense or indemnity (a “REIT Payment”), would constitute gross income to the REIT Partner (or, if the REIT Partner is a “qualified REIT

59

subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, to such REIT) for purposes of Code Section 856(c)(2) or Code Section 856(c)(3), then, notwithstanding any other provision of this Agreement, the amount of such REIT Payments, as selected by the General Partner in its discretion from among items of potential distribution, reimbursement, fees, expenses and indemnities, shall be reduced for any Fiscal Year so that the REIT Payments, as so reduced, for or with respect to such REIT Partner shall not exceed the lesser of:

(1)    an amount equal to the excess, if any, of (a) four and nine-tenths percent (4.9%) of the REIT Partner’s (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, such REIT’s) total gross income (but excluding the amount of any REIT Payments) for the Fiscal Year that is described in subsections (A) through (HI) of Code Section 856(c)(2) over (b) the amount of gross income (within the meaning of Code Section 856(c)(2)) derived by the REIT Partner (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, by such REIT) from sources other than those described in subsections (A) through (HI) of Code Section 856(c)(2) (but not including the amount of any REIT Payments); or

(2)    an amount equal to the excess, if any, of (a) twenty-four percent (24%) of the REIT Partner’s (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, such REIT’s) total gross income (but excluding the amount of any REIT Payments) for the Fiscal Year that is described in subsections (A) through (I) of Code Section 856(c)(3) over (b) the amount of gross income (within the meaning of Code Section 856(c)(3)) derived by the REIT Partner (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, by such REIT) from sources other than those described in subsections (A) through (I) of Code Section 856(c)(3) (but not including the amount of any REIT Payments);

provided, however, that REIT Payments in excess of the amounts set forth in clauses (i) and (ii) above may be made if the General Partner, as a condition precedent, obtains an opinion of tax counsel that the receipt of such excess amounts shall not adversely affect the REIT Partner’s (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, such REIT’s) ability to qualify as a REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a consequence of the limitations set forth in this Section 15.11, such REIT Payments shall carry over and shall be treated as arising in the following Fiscal Year. The purpose of the limitations contained in this Section 15.11 is to prevent any REIT Partner (or, if the REIT Partner is a “qualified REIT subsidiary” (within the meaning of Code Section 856(i)(2)) of a REIT, such REIT) from failing to qualify as a REIT under the Code by reason of such REIT Partner’s share of items, including distributions, reimbursements, fees, expenses or indemnities, receivable directly or indirectly from the Partnership, and this Section 15.11 shall be interpreted and applied to effectuate such purpose.

Section 15.12    No Partition. No Partner nor any successor-in-interest to a Partner shall have the right while this Agreement remains in effect to have any property of the Partnership partitioned, or to file a complaint or institute any proceeding at law or in equity to have such property of the Partnership partitioned, and each Partner, on behalf of itself and its successors and assigns hereby waives any such right. It is the intention of the Partners that the rights of the parties hereto and their successors-in-interest to Partnership property, as among themselves, shall be governed by the terms of this Agreement, and that the rights of the Partners and their successors-in-interest shall be subject to the limitations and restrictions as set forth in this Agreement.

Section 15.13    No Third-Party Rights Created Hereby. The provisions of this Agreement are solely for the purpose of defining the interests of the Partners, inter se; and no other person, firm or entity (i.e., a party who is not a signatory hereto or a permitted successor to such signatory hereto) shall have any right, power, title or interest by way of subrogation or otherwise, in and to the rights, powers, title and provisions of this Agreement. No creditor or other third party having dealings with the Partnership shall have the right to enforce the right or obligation of any Partner to make Capital Contributions or loans to the Partnership or to pursue any other right or remedy hereunder or at law or in equity. None of the rights or obligations of the Partners herein set forth to make

60

Capital Contributions or loans to the Partnership shall be deemed an asset of the Partnership for any purpose by any creditor or other third party, nor may any such rights or obligations be sold, transferred or assigned by the Partnership or pledged or encumbered by the Partnership to secure any debt or other obligation of the Partnership or any of the Partners.

For purposes of the following examples, it is assumed that (a) the Adjustment Factor in effect on June 30, 1995 is 1.0 and (b) on July 1, 1995 (the “Partnership Record Date” for purposes of these examples), prior to the events described in the examples, there are 100 REIT Shares issued and outstanding.

On the Partnership Record Date, the Previous General Partner declares a dividend on its outstanding REIT Shares in REIT Shares. The amount of the dividend is one REIT Share paid in respect of each REIT Share owned. Pursuant to Paragraph (i) of the definition of “Adjustment Factor,” the Adjustment Factor shall be adjusted on the Partnership Record Date, effective immediately after the stock dividend is declared, as follows:

1.0 * 200 OVER 100 = 2.0

Accordingly, the Adjustment Factor after the stock dividend is declared is 2.0.

Example 2

On the Partnership Record Date, the Previous General Partner distributes options to purchase REIT Shares to all holders of its REIT Shares. The amount of the distribution is one option to acquire one REIT Share in respect of each REIT Share owned. The strike price is $4.00 a share. The Value of a REIT Share on the Partnership Record Date is $5.00 per share. Pursuant to Paragraph (ii) of the definition of “Adjustment Factor,” the Adjustment Factor shall be adjusted on the Partnership Record Date, effective immediately after the options are distributed, as follows:

1.0 * {(100 + 100)} OVER {(100 + {100 * $4.00} OVER {$5.00})} = 1.1111

Accordingly, the Adjustment Factor after the options are distributed is 1.1111. If the options expire or become no longer exercisable, then the retroactive adjustment specified in Paragraph (ii) of the definition of “Adjustment Factor” shall apply.

Example 3

On the Partnership Record Date, the Previous General Partner distributes assets to all holders of its REIT Shares. The amount of the distribution is one asset with a fair market value (as determined by the General Partner) of $1.00 in respect of each REIT Share owned. It is also assumed that the assets do not relate to assets received by the Previous General Partner or the General Partner pursuant to a pro rata distribution by the Partnership. The Value of a REIT Share on the Partnership Record Date is $5.00 a share. Pursuant to Paragraph (iii) of the definition of “Adjustment Factor,” the Adjustment Factor shall be adjusted on the Partnership Record Date, effective immediately after the assets are distributed, as follows:

1.0 * {$5.00} OVER {$5.00 - $1.00} = 1.25

Accordingly, the Adjustment Factor after the assets are distributed is 1.25.

PARTNERSHIP UNIT DESIGNATION OF

THE CLASS I HIGH PERFORMANCE PARTNERSHIP UNITS OF

AIMCO PROPERTIES, L.P.

1.     Number of Units and Designation.

A class of Partnership Units is hereby designated as “Class I High Performance Partnership Units,” and the number of Partnership Units initially constituting such class shall be fifteen thousand (15,000), subject to adjustment at the Class I High Performance Valuation Date, as provided in Section 3 hereof.

2.     Definitions.

For purposes of this Partnership Unit Designation, the following terms shall have the meanings indicated in this Section 2. Capitalized terms used and not otherwise defined herein shall have the meanings assigned thereto in the Agreement.

“AIMCO Equity Capitalization” shall mean the quotient obtained by dividing (i) the sum of the AIMCO Market Values for each trading day included in the Measurement Period, by (ii) the number of trading days included in the Measurement Period.

“AIMCO Market Value” shall mean, for any date, the product of (i) the number of REIT Shares and Partnership Units (other than Partnership Preferred Units) outstanding as of the close of business on such date, multiplied by (ii) the Value of a REIT Share on such date.

“AIMCO Total Return” shall mean the Total Return of the REIT Shares for the Measurement Period; provided, however, that, for purposes of calculating the security price of the REIT Shares at the end of the Measurement Period, such price shall be the average of the daily market prices for twenty (20) consecutive trading days ending immediately prior to the Class I High Performance Valuation Date. The market price for any such trading day shall be:

(i)    if the REIT Shares are listed or admitted to trading on any securities exchange or Thethe Nasdaq Stock Market’s National Market System, the volume-weighted average of trading prices on such day, as reported by Bloomberg Financial Markets (or another reliable source selected by the General Partner), or if no trade takes place on such day, the average of the closing bid and asked prices on such day, as reported in the principal consolidated transaction reporting system;

(ii)    if the REIT Shares are not listed or admitted to trading on any securities exchange or Thethe Nasdaq Stock Market’s National Market System, the last reported sale price on such day or, if no sale takes place on such day, the average of the closing bid and asked prices on such day, as reported by a reliable quotation source designated by the General Partner; or

(iii)    if the REIT Shares are not listed or admitted to trading on any securities exchange or Thethe Nasdaq Stock Market’s National Market System and no such last reported sale price or closing bid and asked prices are available, the average of the reported high bid and low asked prices on such day, as reported by a reliable quotation source designated by the General Partner, or if there shall be no bid and asked prices on such day, the average of the high bid and low asked prices, as so reported, on the most recent day (not more than ten (10) days prior to the date in question) for which prices have been so reported;

provided, however, that, if there are no bid and asked prices reported during the ten (10) days prior to the date in question, the market price of the REIT Shares shall be determined by the General Partner acting in good faith on the basis of such quotations and other information as it considers, in its reasonable judgment, appropriate.

“Agreement” shall mean the Agreement of Limited Partnership of the Partnership, as amended, supplemented or restated from time to time.

1

“Change of Control” shall mean the occurrence of any of the following events:

(i)    an acquisition (other than directly from the Previous General Partner) of any voting securities of the Previous General Partner (the “Voting Securities”) by any “person” (as the term “person” is used for purposes of Section 13(d) or Section 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) immediately after which such person has “beneficial ownership” (within the meaning of Rule 13d-3 promulgated under the Exchange Act) (“Beneficial Ownership”) of 20% or more of the combined voting power of the Previous General Partner’s then outstanding Voting Securities; provided, however, in determining whether a Change in Control has occurred, Voting Securities that are acquired in a Non-Control Acquisition (as hereinafter defined) shall not constitute an acquisition that would cause a Change in Control. “Non-Control Acquisition” shall mean an acquisition by (A) an employee benefit plan (or a trust forming a part thereof) maintained by (1) the Previous General Partner or (2) any corporation, partnership or other person of which a majority of its voting power or its equity securities or equity interest is owned directly or indirectly by the Previous General Partner or in which the Previous General Partner serves as a general partner or manager (a “Subsidiary”), (B) the Previous General Partner or any Subsidiary, or (C) any person in connection with a Non-Control Transaction (as hereinafter defined);

(ii)    the individuals who constitute the Board of Directors of the Previous General Partner as of January 1[     ], 19982020 (the “Incumbent Board”) cease for any reason to constitute at least two-thirds (²⁄₃) of the Board of Directors; provided, however, that if the election, or nomination for election by the Previous General Partner’s stockholders, of any new director was approved by a vote of at least two-thirds (²⁄₃) of the Incumbent Board, such new director shall be considered as a member of the Incumbent Board; provided, further, that no individual shall be considered a member of the Incumbent Board if such individual initially assumed office as a result of either an actual or threatened “election contest” (as described in Rule 14a-11 promulgated under the Exchange Act) (an “Election Contest”) or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors (a “Proxy Contest”) including by reason of any agreement intended to avoid or settle any Election Contest or Proxy Contest; or

(iii)    approval by stockholders of the Previous General Partner of: (A) a merger, consolidation, share exchange or reorganization involving the Previous General Partner, unless (1) the stockholders of the Previous General Partner, immediately before such merger, consolidation, share exchange or reorganization, own, directly or indirectly immediately following such merger, consolidation, share exchange or reorganization, at least 80% of the combined voting power of the outstanding voting securities of the corporation that is the successor in such merger, consolidation, share exchange or reorganization (the “Surviving Company”) in substantially the same proportion as their ownership of the Voting Securities immediately before such merger, consolidation, share exchange or reorganization, (2) the individuals who were members of the Incumbent Board immediately prior to the execution of the agreement providing for such merger, consolidation, share exchange or reorganization constitute at least two-thirds (²⁄₃) of the members of the board of directors of the Surviving Company, and (3) no persons (other than the Previous General Partner or any Subsidiary, any employee benefit plan (or any trust forming a part thereof) maintained by the Previous General Partner, the Surviving Company or any Subsidiary, or any person who, immediately prior to such merger, consolidation, share exchange or reorganization had Beneficial Ownership of 15% or more of the then outstanding Voting Securities has Beneficial Ownership of 15% or more of the combined voting power of the Surviving Company’s then outstanding voting securities (a transaction described in clauses (1) through (3) is referred to herein as a “Non-Control Transaction”)); (B) a complete liquidation or dissolution of the Previous General Partner; or (C) an agreement for the sale or other disposition of all or substantially all of the assets of the Previous General Partner to any person (other than a transfer to a Subsidiary).

Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because any person (a “Subject Person”) acquired Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting Securities by the Previous General Partner that, by reducing the number of Voting Securities outstanding, increases the proportional number of shares Beneficially Owned by such Subject Person, provided that if a Change of Control would occur (but for the operation of this sentence) as

2

a result of the acquisition of Voting Securities by the Previous General Partner, and after such share acquisition by the Previous General Partner, such Subject Person becomes the Beneficial Owner of any additional Voting Securities that increases the percentage of the then outstanding Voting Securities Beneficially Owned by such Subject Person, then a Change of Control shall occur.

“Class I High Performance Cash Amount” shall mean, as of any date, the lesser of (i) an amount of cash equal to the product of the amount that a Holder would receive in respect of each Class I High Performance Partnership Unit if the Partnership sold all of its properties at their fair market value (which may be determined by reference to the Value of a REIT Share), paid all of its debts and distributed the remaining proceeds to the Partners as provided in Section 13.2 of the Agreement, determined as of the applicable Valuation Date, or (ii) in the case of a Declination followed by a Public Offering Funding, the Public Offering Funding Amount.

“Class I High Performance Partnership Unit” shall mean a Partnership Unit with the designations, preferences and relative, participating, optional or other special rights, powers and duties as are set forth in this Exhibit.

“Class I High Performance Valuation Date” shall mean the earlier to occur of (i) January 1, 2001, or (ii) the date on which a Change of Control occurs.

“Determination Date” shall mean (i) when used with respect to any dividend or other distribution, the date fixed for the determination of the holders of the securities entitled to receive such dividend or distribution, or, if a dividend or distribution is paid or made without fixing such a date, the date of such dividend or distribution, and (ii) when used with respect to any split, subdivision, reverse stock split, combination or reclassification of securities, the date upon which such split, subdivision, reverse stock split, combination or reclassification becomes effective.

“Excess Return” shall mean the amount (measured as a percentage), if any, by which (i) the AIMCO Total Return exceeds (ii) the Hurdle Rate of Return.

“Ex-Date” shall mean (i) when used with respect to any dividend or distribution, the first date on which the securities on which the dividend or distribution is payable trade regular way on the relevant exchange or in the relevant market without the right to receive such dividend or distribution, and (ii) when used with respect to any split, subdivision, reverse stock split, combination or reclassification of securities, the first date on which the securities trade regular way on such exchange or in such market to reflect such split, subdivision, reverse stock split, combination or reclassification becoming effective.

“Extraordinary Distribution” shall mean the distribution by the Previous General Partner, by dividend or otherwise, to all holders of its REIT Shares of evidences of its indebtedness or assets (including securities) other than cash or REIT Shares.

“Hurdle Rate of Return” shall mean the greater of (x) 115% of the Industry Total Return, or (y) 30% (or, if the Class I High Performance Valuation Date is not January 1, 2001, a percentage equal to the return over the Measurement Period that, if compounded annually over three years, would result in a cumulative return of 30%).

“Industry Total Return” shall mean the Total Return of the securities included in the Industry Peer Group Index for the Measurement Period, with such average determined in a manner consistent with the manner in which such index is calculated; provided, however, that if such Total Return would be less than zero without giving effect to the reinvestment of dividends, then the “Industry Total Return” shall be equal to zero.

“Industry Peer Group Index” shall mean the Morgan Stanley REIT Index or any other similar industry index approved by the Board of Directors of the Previous General Partner.

“Measurement Period” shall mean the period from and including January 1, 1998 to but excluding the Class I High Performance Valuation Date.

3

“Partnership” shall mean AIMCO Properties, L.P., a Delaware limited partnership.

“Total Return” shall mean, for any security and for any period, the cumulative total return for such security over such period, as measured by (i) the sum of (A) the cumulative amount of dividends (excluding any dividend that is paid in the form of such security) paid in respect of such security for such period (assuming that all dividends other than Extraordinary Distributions are reinvested in such security as of the payment date for such dividend based on the security price on the dividend payment date), and (B) an amount equal to (1) the security price at the end of such period, minus (2) the security price at the beginning of such period, divided by (ii) the security price at the beginning of the measurement period; provided, however, that if the foregoing calculation results in a negative number, the “Total Return” shall be equal to zero.

“Value” shall have the meaning set forth in the Agreement, except that Value shall be determined by reference to the average of the daily market prices for twenty (20) consecutive trading days rather than ten (10) consecutive trading days.

3.     Adjustment of Units at Class I High Performance Valuation Date.

(a)    If, on the Class I High Performance Valuation Date there is any Excess Return, then, from and after such date, each Class I High Performance Partnership Unit shall, without any action on the part of the Partnership, the General Partner or the Holder thereof, be automatically adjusted to equal a number of Class I High Performance Partnership Units equal to the quotient obtained by dividing (x) the product of (A) 15% of the Excess Return, multiplied by (B) the AIMCO Equity Capitalization, by (y) the product of (A) 15,000 and (B) the Value of a REIT Share on the Class I High Performance Valuation Date. For illustrative purposes, examples of the calculation of such adjustment are set forth in Annex I hereto.

(b)    If, on the Class I High Performance Valuation Date there is no Excess Return, then, from and after such date, each Class I High Performance Partnership Units shall, without any action on the part of the Partnership, the General Partner or the Holder thereof, be automatically adjusted to equal 1/100 of a Class I High Performance Partnership Unit.

4.     Distributions.

On and after the Class I High Performance Valuation Date, the Holders of Class I High Performance Partnership Units shall be entitled to receive distributions (other than distributions upon liquidation) if, as, when and in the same amounts and of the same type as may be paid to Holders of Partnership Common Units as if each Holder of Class I High Performance Partnership Units held an equal number of Partnership Common Units originally issued on the Class I High Performance Valuation Date.

5.     Allocations.

(a)    From and after the Class I High Performance Valuation Date, Net Income and Net Loss shall be allocated to each of the Holders of Class I High Performance Partnership Units as if each such Holder was the Holder of an equal number of Partnership Common Units originally issued on the Class I High Performance Valuation Date.

(b)    In the event that the Partnership disposes of all or substantially all of its assets in a transaction that will lead to a liquidation of the Partnership pursuant to Article XIII of the Agreement, then, notwithstanding Section 6.3.C of the Agreement, each Holder of Class I High Performance Partnership Units shall be specifically allocated items of Partnership income and gain in an amount sufficient to cause the Capital Account of such Holder to be equal to that of a Holder of an equal number of Partnership Common Units.

4

6.     Redemption.

At any time after December 31, 2016, and subject to the applicable requirements of Federal securities laws and any securities exchange or quotation system rules or regulations, each Holder of Class I High Performance Partnership Units shall have the redemption rights of Qualifying Parties set forth in Section 8.6 of the Agreement, except that (i) all references therein to “Redeemable Units” or “Partnership Common Units” shall be deemed to be references to Class I High Performance Partnership Units, (ii) the first Twelve-Month Period applicable to all Class I High Performance Partnership Units shall be deemed to have passed, (iii) all references therein to “Cash Amount” shall be deemed to be references to the Class I High Performance Cash Amount, and (iv) in the event that the Previous General Partner elects to acquire Class I High Performance Partnership Units that have been tendered for Redemption, the Previous General Partner shall acquire each such Class I High Performance Partnership Unit in exchange for a number of REIT Shares equal to the quotient obtained by dividing the Class I High Performance Cash Amount by the Value of a REIT Share, determined as of the applicable Valuation Date. Notwithstanding anything to the contrary herein, a Holder of Class I High Performance Partnership Units shall not have the right to redeem Class High Performance Partnership Units if the issuance of REIT Shares in exchange for such Class I High Performance Partnership Units would require shareholder approval (which has not been obtained) under the applicable rules of a securities exchange on which the REIT Shares are then listed.

7.     Status of Reacquired Units.

All Class I High Performance Partnership Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8.     Restrictions on Ownership and Transfer.

The restrictions on Transfer set forth in Sections 11.1.B and 11.3.A of the Agreement shall not apply to Transfers of Class I High Performance Partnership Units. Prior to the Class I High Performance Valuation Date, the Class I High Performance Partnership Units shall be owned and held solely by SMP I, L.L.C., a Delaware limited liability company (“SMP”), Richard S. Ellwood, J. Landis Martin, Thomas L. Rhodes and John D. Smith. On or after the Class I High Performance Valuation Date, the Class I High Performance Partnership Units may be Transferred (i) by SMP to (a) any Person who is a member (a “Member”) of SMP immediately prior to such transfer, (b) a Family Member of a Member, (c) a Controlled Entity of a Member, (c) any Person with respect to whom the Member constitutes a Controlled Entity, (d) upon the death of a Member, by will or by the laws of descent and distribution to any Qualified Transferee, and (ii) by any other Person to (a) a Family Member of a such Person, (b) a Controlled Entity of such Person, (c) any other Person with respect to whom such Person constitutes a Controlled Entity, (d) upon the death of such Person, by will or by the laws of descent and distribution to any Qualified Transferee,

9.     Adjustments.

(a)     [intentionally omitted]

(b)    In the event that, on or after January 1, 1998, the Previous General Partner (i) declares or pays a dividend on its outstanding REIT Shares in REIT Shares or makes a distribution to all holders of its outstanding REIT Shares in REIT Shares, (ii) splits or subdivides its outstanding REIT Shares, (iii) effects a reverse stock split or otherwise combines its outstanding REIT Shares into a smaller number of REIT Shares, or (iv) otherwise reclassifies its outstanding REIT Shares, then, for purposes of determining the AIMCO Total Return, each price of a REIT Share determined as of a date on or after the Ex-Date for such transaction shall be adjusted by multiplying such price by a fraction (x) the numerator of which shall be the number of REIT Shares issued and outstanding on the Determination Date for such dividend, distribution, split, subdivision, reverse stock split, combination or reclassification (assuming for such purposes that such dividend, distribution, split, subdivision,

5

reverse split or combination has occurred as of such time) and (y) the denominator of which shall be the actual number of REIT Shares (determined without the above assumption) issued and outstanding on the Determination Date for such dividend, distribution, split, subdivision, reverse stock split, combination or reclassification. The General Partner is authorized to adjust the market price for any trading day as may be necessary, in its judgment, to reflect an event that occurs at any time after the commencement of the relevant valuation period that would unfairly distort the Value of a REIT Share, including, without limitation, a stock dividend, split subdivision, reverse stock split, or share combination.

(c)    The General Partner shall have authority to appropriately adjust the AIMCO Market Value, the AIMCO Total Return or the Value of a REIT Share if any other transaction or circumstance occurs or arises that would have an inequitable result.

10.    General.

The ownership of Class I High Performance Partnership Units may (but need not, in the sole and absolute discretion of the General Partner) be evidenced by one or more certificates. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent conversion, redemption, or any other event having an effect on the ownership of, Class I High Performance Partnership Units.

(b)    on a parity with the Class One Partnership Preferred Units, as to the payment of distributions and as to distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class One Partnership Preferred Units if (i) such class or series of Partnership Units shall be Class G Partnership Preferred Units or (ii) the holders of such class or series of Partnership Units and the Class One Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class One Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if (i) such class or series of Partnership Units shall be Partnership Common Units or Class I High Performance Partnership Units or (ii) the holders of Class One Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

4.     Quarterly Cash Distributions.

(a)    Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner, quarterly cash distributions at the rate of $2.00 per Preferred Unit. Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”),

3

commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

(b)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(c)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(d)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.     Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to effectively enable them to receive a liquidation preference (the “Liquidation Preference”) per Preferred Unit equal to the sum of (i) 91.93 (which is the quotient obtained by dividing $8 by 8.75%), plus (ii) any accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders will not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain

4

will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following certain allocations made by the Partnership, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.     Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (such Preferred Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for REIT Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for REIT Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such REIT Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for REIT Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for REIT Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of REIT Shares equal to the REIT Shares Amount for such number of the Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment

5

letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The REIT Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible REIT Shares, free of any pledge, lien, encumbrance or restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such REIT Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such REIT Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. REIT Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suite 11001700, Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for REIT Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of REIT Shares (“Registrable Shares”) equal to the REIT Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to

6

effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners, as the case may be, to an equitable Percentage Interest adjustment.

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for the REIT Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Preferred Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of an equal number of Partnership Common Units. Any Preferred Units so contributed to the Special Limited PartnerPartners shall be converted into Partnership Common Units.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(4)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(5)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(6)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a

7

Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of REIT Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(a) or (b)) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver REIT Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or REIT Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners ) are less

8

than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

7.     Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8.     General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Class One Partnership Preferred Units.

9.     Allocations of Income and Loss.

For each taxable year, (i) each holder of Preferred Units will be allocated net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (ii) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other interests in the Partnership. Upon liquidation, dissolution or winding up of the Partnership, the holders of Preferred Units will be allocated income and gain sufficient to enable them to realize the Liquidation Preference in full.

10.    Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. So long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership units, including, without limitation, any Partnership units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. The Partnership shall give the holders of the Preferred Units at least twenty-one (21) days’ advance notice of the proposed issuance of any Senior Partnership Units. With respect to the exercise of the above described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

11.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer applicable to Common Units, as set forth in the Agreement.

4.     Quarterly Cash Distributions.

(a)    Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner, quarterly cash distributions at the rate of $0.50 per Preferred Unit; provided, however, that at any time and from time to time on or after March 1, 2005, the Partnership may adjust the quarterly cash distribution rate on the Preferred Units to equal 25% of the lower of (i) two percent (2%) plus the annual interest rate then applicable to U.S. Treasury notes with a maturity of five years and (ii) the annual dividend rate on the class or series of preferred stock most recently issued by the Previous General Partner that (x) is not convertible into another security of the Previous General Partner at the option of the holder and (y) ranks on a parity with its Class H Cumulative Preferred Stock. Such adjustment shall become effective upon the date the Partnership issues a notice to such effect to the holders of the Preferred Units. Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

(b)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(c)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, the Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(d)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration,

4

payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.     Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to effectively enable them to receive a liquidation preference (the “Liquidation Preference”) of (i) $25 per Preferred Unit, plus (ii) accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders shall not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Partnership Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following certain allocations made by the Partnership, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.     Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (any Preferred Units tendered for Redemption being hereafter “Tendered Units”) in exchange (a “Redemption”) for Common Shares or Preferred Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for Common Shares or Preferred Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such Common Shares or Preferred Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be

5

treated, for federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for Common Shares or Preferred Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for Common Shares or Preferred Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for (i) a number of Common Shares equal to the Common Shares Amount for such number of Tendered Units, (ii) if (x) the Notice of Redemption for such Tendered Units is received by the General Partner after the second (2nd) anniversary of the Tendering Party becoming a holder of such Preferred Units and (y) the Preferred Shares are then listed on the New York Stock Exchange or another national securities exchange, a number of Preferred Shares equal to such number of Tendered Units, or (iii) any combination of (i) and (ii). The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The Common Shares or Preferred Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and non-assessable shares, free of any pledge, lien, encumbrance or restriction other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such Common Shares or Preferred Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such Common Shares or Preferred Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. Common Shares or Preferred Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suite 11001700, Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

6

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for Common Shares or Preferred Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of Common Shares or Preferred Shares (“Registrable Shares”) equal to the Common Shares or Preferred Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for the Common Shares or Preferred Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    Each Tendering Party (a) may effect a Redemption only once in each fiscal quarter of a Twelve-Month Period and (b) may not effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

7

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in this Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart- Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of Common Shares or Preferred Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own Common Shares or Preferred Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional Common Shares, Preferred Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of Common Shares or Preferred Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(a) or (b)) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own Common Shares or Preferred Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

8

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver Common Shares or Preferred Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or Common Shares or Preferred Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in Common Shares or Preferred Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

7.     Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8.     General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Preferred Units.

9.     Allocations of Income and Loss.

For each taxable year, (i) each holder of Preferred Units will be allocated net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (ii) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other

9

interests in the Partnership. Upon liquidation, dissolution or winding up of the Partnership, the holders of Preferred Units will be allocated income and gain sufficient to enable them to realize the Liquidation Preference in full.

10.    Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. As long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership Units, including, without limitation, any Partnership Units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. With respect to the exercise of the above-described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

11.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer applicable to Common Units, as set forth in the Agreement.

3.     Ranking.

Any class or series of Partnership Units of the Partnership shall be deemed to rank:

(a)    prior or senior to the Class Three Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if the holders of such class or

3

series shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class Three Partnership Preferred Units (the Partnership Units referred to in this paragraph being hereinafter referred to, collectively, as “Senior Partnership Units”);

(b)    on a parity with the Class Three Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class Three Partnership Preferred Units if (i) such class or series of Partnership Units shall be Class G Partnership Preferred Units, Class One Partnership Preferred Units or Class Two Partnership Preferred Units or (ii) the holders of such class or series of Partnership Units and the Class Three Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class Three Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if (i) such class or series of Partnership Units shall be Partnership Common Units or Class I High Performance Partnership Units or (ii) the holders of Class Three Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

4.     Quarterly Cash Distributions.

(a)    The “Quarterly Distribution Amount,” as of any date, shall be equal to (i) the Distribution Rate then in effect, multiplied by (ii) $25, and divided by (iii) four. Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner, quarterly cash distributions in an amount per Preferred Unit equal to the Quarterly Distribution Amount in effect as of the date such distribution is declared by the General Partner, and no more. On each Reset Date, the Distribution Rate thereafter in effect shall be adjusted by the General Partner to equal the lesser of (i) the Distribution Rate in effect immediately prior to such Reset Date or (ii) the Dividend Yield of the class of Qualifying Preferred Stock most recently issued by the Previous General Partner or, if there is no class of Qualifying Preferred Stock of the Previous General Partner outstanding as of any Reset Date, the Weighted Average of Preferred Stock Dividend Yields, calculated as of the end of the calendar quarter immediately preceding such Reset Date; provided, further, that if for any reason there are no classes of Qualifying Preferred Stock of the type described in the definition of “Weighted Average of Preferred Stock Dividend Yields” outstanding on any Reset Date and the reference to the Weighted Average of Preferred Stock Dividend Yields would otherwise be determinative of the calculation of the adjusted Distribution Rate on such Reset Date, the adjusted Distribution Rate for the succeeding five (5) year period shall be the Distribution Rate in effect immediately prior to such Reset Date. Upon any such adjustment of the Distribution Rate, the General Partner shall send a notice describing such adjustment to the holders of the Preferred Units at their respective addresses, as set forth on Exhibit A to the Agreement.

(b)    Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be

4

payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. If the Preferred Units are issued other than on a record date for the payment of distributions to the holders of Preferred Units, the Quarterly Distribution Amount shall, for any quarter in which the Distribution Rate changes on any Reset Date, be appropriately prorated based on the portions of such quarter during which the different Distribution Rates were in effect, on the basis of twelve 30-day months and a 360-day year. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

(c)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(d)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(e)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.     Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to the extent necessary to enable them to receive a liquidation preference (the “Liquidation Preference”) per Preferred Unit equal to the sum of (i) $25 plus (ii) any accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders will not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership.

5

(b)    If, upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following appropriate allocations of Partnership income, gain, deduction and loss, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to the extent necessary to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.     Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (such Preferred Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for REIT Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for REIT Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such REIT Shares to the Tendering Party pursuant to the terms set forth in this Section 6 in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for Federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for REIT Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for REIT Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of REIT Shares equal to the REIT Shares Amount for such number of the Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The REIT Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible REIT Shares, free of any pledge, lien, encumbrance or

restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such REIT Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such REIT Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. REIT Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suite 11001700 , Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for REIT Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of REIT Shares (“Registrable Shares”) equal to the REIT Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after

7

receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for REIT Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Preferred Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of an equal number of Partnership Common Units. Any Preferred Units so contributed to the Special Limited PartnerPartners shall be converted into Partnership Common Units.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    No Tendering Party may (a) effect a Redemption more than once in any fiscal quarter of a Twelve-Month Period or (b) effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

8

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of REIT Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(a) or (b)) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver REIT Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or REIT Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner hereunder.

9

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

7.     Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8.     General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Class Three Partnership Preferred Units.

9.     Allocations of Income and Loss.

Subject to the terms of Section 5 hereof, for each taxable year, (i) each holder of Preferred Units will be allocated, to the extent possible, net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (ii) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other interests in the Partnership.

10.    Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. As long as my Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership units, including, without limitation, any Partnership units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. With respect to the exercise of the above described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

11.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer as are, and the holders of Preferred Units shall be entitled to the same rights of transfer as are, applicable to Common Units as set forth in the Agreement.

PARTNERSHIP UNIT DESIGNATION OF

THE CLASS FOUR PARTNERSHIP PREFERRED UNITS OF

AIMCO PROPERTIES, L.P.

1.    Number of Units and Designation.

A class of Partnership Preferred Units is hereby designated as “Class Four Partnership Preferred Units,” and the number of Partnership Preferred Units constituting such class shall be 5,100,000.

2.    Definitions.

Capitalized terms used and not otherwise defined herein shall have the meanings assigned thereto in the Agreement, as modified by this Partnership Unit Designation and the defined terms used herein. For purposes of this Partnership Unit Designation, the following terms shall have the respective meanings ascribed below:

“Adjustment Factor” means 1.0; provided, however, that in the event that:

(i)    the Previous General Partner (a) declares or pays a dividend on its outstanding REIT Shares in REIT Shares or makes a distribution to all holders of its outstanding REIT Shares in REIT Shares, (b) splits or subdivides its outstanding REIT Shares or (c) effects a reverse stock split or otherwise combines its outstanding REIT Shares into a smaller number of REIT Shares, the Adjustment Factor shall be adjusted by multiplying the Adjustment Factor previously in effect by a fraction, (i) the numerator of which shall be the number of REIT Shares issued and outstanding on the record date for such dividend, distribution, split, subdivision, reverse split or combination (assuming for such purposes that such dividend, distribution, split, subdivision, reverse split or combination has occurred as of such time) and (ii) the denominator of which shall be the actual number of REIT Shares (determined without the above assumption) issued and outstanding on the record date for such dividend, distribution, split, subdivision, reverse split or combination;

(ii)    the Previous General Partner distributes any rights, options or warrants to all holders of its REIT Shares to subscribe for or to purchase or to otherwise acquire REIT Shares (or other securities or rights convertible into, exchangeable for or exercisable for REIT Shares) at a price per share less than the Value of a REIT Share on the record date for such distribution (each a “Distributed Right”), then the Adjustment Factor shall be adjusted by multiplying the Adjustment Factor previously in effect by a fraction (a) the numerator of which shall be the number of REIT Shares issued and outstanding on the record date plus the maximum number of REIT Shares purchasable under such Distributed Rights and (b) the denominator of which shall be the number of REIT Shares issued and outstanding on the record date plus a fraction (1) the numerator of which is the maximum number of REIT Shares purchasable under such Distributed Rights times the minimum purchase price per REIT Share under such Distributed Rights and (2) the denominator of which is the Value of a REIT Share as of the record date; provided, however, that, if any such Distributed Rights expire or become no longer exercisable, then the Adjustment Factor shall be adjusted, effective retroactive to the date of distribution of the Distributed Rights, to reflect a reduced maximum number of REIT Shares or any change in the minimum purchase price for the purposes of the above fraction; and

(iii)    the Previous General Partner shall, by dividend or otherwise, distribute to all holders of its REIT Shares evidences of its indebtedness or assets (including securities, but excluding any dividend or distribution referred to in subsection (i) above), which evidences of indebtedness or assets relate to assets not received by the Previous General Partner, the General Partner and/or the Special Limited PartnerPartners pursuant to a pro rata distribution by the Partnership, then the Adjustment Factor shall be adjusted to equal the amount determined by multiplying the Adjustment Factor in effect immediately prior to the close of business on the date fixed for determination of shareholders entitled to receive such distribution by a fraction (i) the numerator shall be such Value of a REIT Share on the date fixed for such determination and (ii) the denominator shall be the Value of a REIT Share on the dates fixed for such determination less the

1

then fair market value (as determined by the General Partner, whose determination shall be conclusive) of the portion of the evidences of indebtedness or assets so distributed applicable to one REIT Share.

Any adjustments to the Adjustment Factor shall become effective immediately after the effective date of such event, retroactive to the record date, if any, for such event.

“Agreement” shall mean the Agreement of Limited Partnership of the Partnership, as amended, supplemented or restated from time to time.

“Class Four Partnership Preferred Unit” or “Preferred Unit” shall mean a Partnership Preferred Unit with the designations, preferences and relative, participating, optional or other special rights, powers and duties as are set forth in this Partnership Unit Designation.

“Common Shares” shall mean the shares of Class A Common Stock of the Previous General Partner.

“Common Shares Amount” shall mean, with respect to any Tendered Units, a number of Common Shares equal to the quotient obtained by dividing (i) the Cash Amount for such Tendered Units, by (ii) the Market Value of a Common Share calculated as of the date of receipt by the General Partner of a Notice of Redemption for such Tendered Units.

“Conversion Price” shall mean, as of any date, the quotient obtained by dividing $45 by the Adjustment Factor in effect as of such date.

“Current Market Price” of a share of any Equity Stock shall mean the closing price, regular way on such day, or, if no sale takes place on such day, the average of the reported closing bid and asked prices, regular way, on such day, in either case as reported on the principal national securities exchange on which such securities are listed or admitted for trading, or, if such security is not quoted on any national securities exchange, on the NASDAQNasdaq National Market or if such security is not quoted on the NASDAQNasdaq National Market, the average of the closing bid and asked prices on such day in the over-the-counter market as reported by NASDAQNasdaq or, if bid and asked prices for each security on such day shall not have been reported through NASDAQNasdaq, the average of the bid and asked prices on such day as furnished by any New York Stock Exchange or National Association of Securities Dealers, Inc. member firm regularly making a market in such security selected for such purpose by the Chief Executive Officer of the General Partner or the Board of Directors of the General Partner or if any class or series of securities are not publicly traded, the fair value of the shares of such class as determined reasonably and in good faith by the Board of Directors of the General Partner.

For purposes of calculating the amounts of any Inflows, all distributions received in property shall be deemed to have a value equal to the Market Value of such distributions as of the date such distribution is received.

3.    Ranking.

Any class or series of Partnership Units of the Partnership shall be deemed to rank:

(a)    prior or senior to the Class Four Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class Four Partnership Preferred Units (the Partnership Units referred to in this paragraph being hereinafter referred to, collectively, as “Senior Partnership Units”);

(b)    on a parity with the Class Four Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class Four Partnership Preferred Units if (i) such class or series of Partnership Units shall be Class G Partnership Preferred Units, Class One Partnership Preferred Units, Class Two Partnership Preferred Units or Class Three Partnership Preferred Units, or (ii) the holders of such class or series of Partnership Units and the Class Four Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class Four Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if (i) such class or series of Partnership Units shall be Partnership Common Units or Class I High Performance Partnership Units or (ii) the holders of Class Four Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

4.    Quarterly Cash Distributions.

(a)    Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner, quarterly cash distributions at the rate of $0.50 per Preferred Unit. Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

5

(b)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(c)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, the Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(d)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.    Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to effectively enable them to receive a liquidation preference (the “Liquidation Preference”) of (i) $25 per Preferred Unit, plus (ii) accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders shall not be entitled to any further allocation of income or gain. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Partnership Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following certain allocations made by the Partnership, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

6

(d)    Upon any liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.    Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (any Preferred Units tendered for Redemption being hereafter “Tendered Units”) in exchange (a “Redemption”) for Common Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for Common Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such Common Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for Common Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for Common Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of Common Shares equal to the Common Shares Amount for such number of Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The Common Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and non-assessable shares, free of any pledge, lien, encumbrance or restriction other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such Common Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such Common Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. Common Shares issued upon an acquisition of the Tendered Units

7

by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suite 11001700 , Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for Common Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of Common Shares (“Registrable Shares”) equal to the Common Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

8

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for the Common Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    Each Tendering Party (a) may effect a Redemption only once in each fiscal quarter of a Twelve-Month Period and (b) may not effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart- Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

9

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of Common Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own Common Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional Common Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of Common Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(a) or (b)) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own Common Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver Common Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or Common Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in Common Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners ) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

10

7.    Conversion.

(a)     (i) Subject to and upon compliance with the provisions of this Section 7, a holder of Class Four Partnership Preferred Units shall have the right, at such holder’s option, to convert such units, in whole or in part, into the number of Partnership Common Units per Class Four Partnership Preferred Unit obtained by dividing the Liquidation Preference (excluding any accumulated, accrued and unpaid distributions) per Class Four Partnership Preferred Unit by the Conversion Price in effect at the time and on the date provided for in subparagraph (b)(iv) of this Section 7. In order to exercise the conversion right, the holder of each Class Four Partnership Preferred Unit to be converted shall surrender the certificate representing such unit, duly endorsed or assigned to the Partnership or in blank, at the office of the Transfer Agent, accompanied by written notice to the Partnership that the holder thereof elects to convert such Class Four Partnership Preferred Unit.

(i)    With respect to any Class Four Partnership Preferred Units that have been issued and outstanding for at least two (2) years, if, as of any date, the Internal Rate of Return exceeds 12.5%, then the Partnership shall have the right, but not the obligation, to cause such Class Four Partnership Preferred Units to be converted, in whole or in part, into the number of Partnership Common Units per Class Four Partnership Preferred Unit obtained by dividing the Liquidation Preference (excluding any accumulated, accrued and unpaid distributions) per Class Four Partnership Preferred Unit by the Conversion Price in effect at the time and on the date provided for in subparagraph (b)(iv) of this Section 7. In order to exercise the conversion right, the Partnership shall send notice of such conversion to each holder of record of Class Four Partnership Preferred Units no later than five Business Days after a date on which the Internal Rate of Return exceeds 12.5%. Such notice shall be provided by facsimile or, if facsimile is not available, then by first class mail, postage prepaid, at such holders’ address as the same appears on the records of the Partnership. Any notice which was transmitted or mailed in the manner herein provided shall be conclusively presumed to have been duly given on the date received by the holder. Each such notice shall state, as appropriate: (1) the date of conversion, which date may be any date within one business day following the date on which the notice is transmitted or mailed; (2) the number of units of Class Four Partnership Preferred Units to be converted and, if fewer than all such units held by such holder are to be converted, the number of such units to be converted; and (3) the then current Conversion Price. Upon receiving such notice of conversion, each such holder shall promptly surrender the certificates representing such Class Four Partnership Preferred Units as are being converted on the conversion date, duly endorsed or assigned to the Partnership or in blank, at the office of the Transfer Agent; provided, however, that the failure to so surrender any such certificates shall not in any way affect the validity of the conversion of the underlying Class Four Partnership Preferred Units into Partnership Common Units.

(b)     (i) Unless the Partnership Common Units issuable on conversion are to be issued in the same name as the name in which such Class Four Partnership Preferred Units are registered, each such unit surrendered following conversion shall be accompanied by instruments of transfer, in form satisfactory to the Partnership, duly executed by the holder or such holder’s duly authorized representative, and an amount sufficient to pay any transfer or similar tax (or evidence reasonably satisfactory to the Partnership demonstrating that such taxes have been paid).

(i)    A holder of Class Four Partnership Preferred Units shall, as of the date of the conversion of such units to Partnership Common Units, be entitled to receive a cash payment in respect of any distributions (whether or not earned or declared) that are accumulated, accrued and unpaid thereon as of the time of such conversion, provided, however, that payment in respect of any distributions on such units that has been declared but for which the Distribution Payment Date has not yet been reached shall be payable as of such Distribution Payment Date. Except as provided above, the Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on converted units.

(ii)    As promptly as practicable after the surrender of certificates for Class Four Partnership Preferred Units as aforesaid, and in any event no later than three business days after the date of such surrender, the Partnership shall issue and deliver at such office to such holder, or send on such holders’ written order, a

11

certificate or certificates for the number of full Partnership Common Units issuable upon the conversion of such Class Four Partnership Preferred Units in accordance with the provisions of this Section 7, and any fractional interest in respect of a Partnership Common Unit arising upon such conversion shall be settled as provided in paragraph (c) of this Section 7.

(iii)    Each conversion shall be deemed to have been effected (x) in the case of a conversion pursuant to subparagraph (a)(i) of this Section 7 immediately prior to the close of business on the date on which the certificates for Class Four Partnership Preferred Units shall have been surrendered and such notice received by the Partnership as provided in subparagraph (a)(i) of this Section 7, and (y) in the case of a conversion pursuant to subparagraph (a)(ii) of this Section 7, immediately prior to the close of business on the date identified as the conversion date in the notice of conversion sent by the Partnership pursuant to subparagraph (a)(ii) of this Section 7; and, in the case of (x) or (y), the person or persons in whose name or names any certificate or certificates for Partnership Common Units shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the units represented thereby at such time on such date, and such conversion shall be at the Conversion Price in effect at such time on such date, unless the transfer books of the Partnership shall be closed on that date, in which event such person or persons shall be deemed to become such holder or holders of record at the close of business on the next succeeding day on which such transfer books are open, but such conversion shall be at the Conversion Price in effect on the date in the notice of conversion sent by the Partnership as aforesaid.

(c)    No fractional Partnership Common Units or scrip representing fractions of a Partnership Common Unit shall be issued upon conversion of the Class Four Partnership Preferred Units. Instead of any fractional interest in a Partnership Common Unit that would otherwise be deliverable upon the conversion of Class Four Partnership Preferred Units, the Partnership shall pay to the holder of such units an amount of cash equal to the product of (i) such fraction and (ii) the value of a REIT Share as of the date of conversion. If more than one of any holder’s units shall be converted at one time, the number of full Partnership Common Units issuable upon conversion thereof shall be computed on the basis of the aggregate number of Class Four Partnership Preferred Units so converted.

(d)    If the Partnership shall be a party to any transaction (including with limitation a merger, consolidation, statutory exchange, sale of all or substantially all of the Partnership’s assets or recapitalization of the Partnership Common Units, but excluding any transaction as to which a charge in the Adjustment Factor would be effected) (each of the foregoing being referred to herein as a “Transaction”), in each case, as a result of which Partnership Common Units shall be converted into the right to receive securities or other property (including cash or any combination thereof), each Class Four Partnership Preferred Unit which is not converted into the right to receive securities or other property in connection with such Transaction shall thereupon be convertible into the kind and amount of securities and other property (including cash or any combination thereof) receivable upon such consummation by a holder of that number of Partnership Common Units into which Class Four Partnership Preferred Units were convertible immediately prior to such Transaction. The Partnership shall not be a party to any transaction unless the terms of such Transaction are consistent with the provisions of this paragraph (d), and it shall not consent or agree to the occurrence of any Transaction until the Partnership has entered into an agreement with the successor or purchasing entity, as the case may be, for the benefit of the holders of the Class Four Partnership Preferred Units that will contain provisions enabling the holders of the Class Four Partnership Preferred Units that remain outstanding after such Transaction to convert into the consideration received by holders of Partnership Common Units at the Conversion Price in effect immediately prior to such Transaction. The provisions of this Paragraph (d) shall apply to successive Transactions.

(e)    Whenever the Conversion Price is adjusted as herein provided (whether pursuant to paragraph (d) of this Section 7 or as a result of a change in the Adjustment Factor), the General Partner shall promptly file with the Transfer Agent an officer’s certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment which certificate shall be conclusive evidence of the correctness of such adjustment absent manifest error. Promptly after delivery of such certificate, the General

Partner shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the effective date such adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Price to each holder of Class Four Partnership Preferred Units at such holder’s address as shown on the records of the Partnership.

(f)    In any case in which an adjustment to the Adjustment Factor shall become effective immediately after the effective date of an event, retroactive to the record date, if any, for such event, the Partnership may defer until the occurrence of such event (A) issuing to the holder of any Class Four Partnership Preferred Units converted after such record date and before the occurrence of such event the additional Partnership Common Units issuable upon such conversion by reason of the adjustment required by such event over and above the Partnership Common Units issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount of cash in lieu of any fraction pursuant to Section 7(c).

(g)    There shall be no adjustment of the Conversion Price in case of the issuance of any unit of the Partnership except as specifically set forth in the definition of “Adjustment Factor” or in this Section 7. In addition, notwithstanding any other provision contained in the definition of “Adjustment Factor” or in this Section 7, there shall be no adjustment of the Conversion Price upon the payment of any cash distributions on any units of the Partnership.

(h)    If the Partnership shall take any action affecting the Partnership Common Units, other than action described in the definition of “Adjustment Factor” or in this Section 7 that, in the opinion of the General Partner would materially adversely affect the conversion rights of the holders of Class Four Partnership Preferred Units, the Conversion Price for the Class Four Partnership Preferred Units may be adjusted, to the extent permitted by law in such manner, if any, and at such time as the General Partner, in its sole discretion, may determine to be equitable under the circumstances.

(i)    The Partnership will pay any and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of Partnership Common Units or other securities or property on conversion of Class Four Partnership Preferred Units pursuant hereto; provided, however, that the Partnership shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue or delivery of Partnership Common Units or other securities or property in a name other than that of the holder of the Class Four Partnership Preferred Units to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Partnership the amount of any such tax or established, to the reasonable satisfaction of the Partnership, that such tax has been paid.

(j)    In addition to any other adjustment required hereby, to the extent permitted by law, the Partnership from time to time may decrease the Conversion Price by any amount, permanently or for a period of at least twenty Business Days, if the decrease is irrevocable during the period.

(k)    For purposes of the definition of “Twelve-Month Period” in the Agreement, any holder of Class Four Partnership Preferred Units that have been converted to Partnership Common Units shall be deemed to have acquired such Partnership Common Units when such Class Four Partnership Units were acquired.

8.    Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

9.    General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Preferred Units.

13

10.    Allocations of Income and Loss.

For each taxable year, each holder of Preferred Units will be allocated a portion of the Net Income and Net Loss of the Partnership equal to the portion of the Net Income and Net Loss of the Partnership that would be allocated to such holder pursuant to Article 6 of the Agreement if such holder held a number of Partnership Common Units equal to (i) the number of Preferred Units held by such holder, multiplied by (ii) 0.625. Upon liquidation, dissolution or winding up of the Partnership, the Partnership shall endeavor to allocate income and gain to the holders of the Preferred Units such that the Capital Accounts related to the Preferred Units are equal to their Liquidation Preference.

11.    Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. As long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership Units, including, without limitation, any Partnership Units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to materially and adversely affect the rights

or preferences of the holders of Preferred Units. With respect to the exercise of the above-described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

12.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer applicable to Common Units, as set forth in the Agreement.

PARTNERSHIP UNIT DESIGNATION OF

THE CLASS SIX PARTNERSHIP PREFERRED UNITS OF

AIMCO PROPERTIES, L.P.

1.    Number of Units and Designation.

(ii)    the Previous General Partner distributes any rights, options or warrants to all holders of its REIT Shares to subscribe for or to purchase or to otherwise acquire REIT Shares (or other securities or rights convertible into, exchangeable for or exercisable for REIT Shares) at a price per share less than the Value of a REIT Share on the record date for such distribution (each a “Distributed Right”), then the Adjustment Factor shall be adjusted by multiplying the Adjustment Factor previously in effect by a fraction (a) the numerator of which shall be the number of REIT Shares issued and outstanding on the record date plus the maximum number of REIT Shares purchasable under such Distributed Rights and (b) the denominator of which shall be the number of REIT Shares issued and outstanding on the record date plus a fraction (1) the numerator of which is the maximum number of REIT Shares purchasable under such Distributed Rights times the minimum purchase price per REIT Share under such Distributed Rights and (2) the denominator of which is the Value of a REIT Share as of the record date; provided, however, that, if any such Distributed Rights expire or become no longer exercisable, then the Adjustment Factor shall be adjusted, effective retroactive to the date of distribution of the Distributed Rights, to reflect a reduced maximum number of REIT Shares or any change in the minimum purchase price for the purposes of the above fraction; and

(iii)    the Previous General Partner shall, by dividend or otherwise, distribute to all holders of its REIT Shares evidences of its indebtedness or assets (including securities, but excluding any dividend or distribution referred to in subsection (i) above), which evidences of indebtedness or assets relate to assets not received by the Previous General Partner, the General Partner and/or the Special Limited PartnerPartners pursuant to a pro rata distribution by the Partnership, then the Adjustment Factor shall be adjusted to equal the amount determined by multiplying the Adjustment Factor in effect immediately prior to the close of business on the date fixed for determination of shareholders entitled

1

to receive such distribution by a fraction (i) the numerator shall be such Value of a REIT Share on the date fixed for such determination and (ii) the denominator shall be the Value of a REIT Share on the dates fixed for such determination less the then fair market value (as determined by the General Partner, whose determination shall be conclusive) of the portion of the evidences of indebtedness or assets so distributed applicable to one REIT Share.

Any adjustments to the Adjustment Factor shall become effective immediately after the effective date of such event, retroactive to the record date, if any, for such event.

“Agreement” shall mean the Agreement of Limited Partnership of the Partnership, as amended, supplemented or restated from time to time.

“Class Six Partnership Preferred Unit” or “Preferred Unit” shall mean a Partnership Preferred Unit with the designations, preferences and relative, participating, optional or other special rights, powers and duties as are set forth in this Partnership Unit Designation.

“Conversion Price” shall mean, as of any date, the quotient obtained by dividing $50 by the Adjustment Factor in effect as of such date.

“Current Market Price” of a share of any Equity Stock shall mean the closing price, regular way on such day, or, if no sale takes place on such day, the average of the reported closing bid and asked prices, regular way, on such day, in either case as reported on the principal national securities exchange on which such securities are listed or admitted for trading, or, if such security is not quoted on any national securities exchange, on the NASDAQNasdaq National Market or if such security is not quoted on the NASDAQNasdaq National Market, the average of the closing bid and asked prices on such day in the over-the-counter market as reported by NASDAQNasdaq or, if bid and asked prices for each security on such day shall not have been reported through NASDAQNasdaq, the average of the bid and asked prices on such day as furnished by any New York Stock Exchange or National Association of Securities Dealers, Inc. member firm regularly making a market in such security selected for such purpose by the Chief Executive Officer of the General Partner or the Board of Directors of the General Partner or if any class or series of securities are not publicly traded, the fair value of the shares of such class as determined reasonably and in good faith by the Board of Directors of the General Partner.

Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

5

(b)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(c)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, the Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(d)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.    Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to effectively enable them to receive a liquidation preference (the “Liquidation Preference”) of (i) $25 per Preferred Unit, plus (ii) accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders shall not be entitled to any further allocation of income or gain. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Partnership Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following certain allocations made by the Partnership, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.    Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (any Preferred Units tendered for Redemption being hereafter “Tendered Units”) in exchange (a “Redemption”) for Common Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for Common Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such Common Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for Common Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for Common Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of Common Shares equal to the Common Shares Amount for such number of Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The Common Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and non-assessable shares, free of any pledge, lien, encumbrance or restriction other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such Common Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such Common Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. Common Shares issued upon an acquisition of the Tendered Units

7

by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suite 11001700 , Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for Common Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of Common Shares (“Registrable Shares”) equal to the Common Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

8

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for the Common Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    Each Tendering Party (a) may effect a Redemption only once in each fiscal quarter of a Twelve-Month Period and (b) may not effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart- Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

9

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of Common Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own Common Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional Common Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of Common Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(a) or (b)) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own Common Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver Common Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or Common Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in Common Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners ) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

10

7.    Conversion.

(a)    (i) Subject to and upon compliance with the provisions of this Section 7, a holder of Class Six Partnership Preferred Units shall have the right, at such holder’s option, to convert such units, in whole or in part, into the number of Partnership Common Units per Class Six Partnership Preferred Unit obtained by dividing the Liquidation Preference (excluding any accumulated, accrued and unpaid distributions) per Class Six Partnership Preferred Unit by the Conversion Price in effect at the time and on the date provided for in subparagraph (b)(iv) of this Section 7. In order to exercise the conversion right, the holder of each Class Six Partnership Preferred Unit to be converted shall surrender the certificate representing such unit, duly endorsed or assigned to the Partnership or in blank, at the office of the Transfer Agent, accompanied by written notice to the Partnership that the holder thereof elects to convert such Class Six Partnership Preferred Unit.

(i)    With respect to any Class Six Partnership Preferred Units that have been issued and outstanding for at least three (3) years, if, as of any date, the Internal Rate of Return exceeds 12.5%, then the Partnership shall have the right, but not the obligation, to cause such Class Six Partnership Preferred Units to be converted, in whole or in part, into the number of Partnership Common Units per Class Six Partnership Preferred Unit obtained by dividing the Liquidation Preference (excluding any accumulated, accrued and unpaid distributions) per Class Six Partnership Preferred Unit by the Conversion Price in effect at the time and on the date provided for in subparagraph (b)(iv) of this Section 7. In order to exercise the conversion right, the Partnership shall send notice of such conversion to each holder of record of Class Six Partnership Preferred Units no later than five Business Days after a date on which the Internal Rate of Return exceeds 12.5%. Such notice shall be provided by facsimile or, if facsimile is not available, then by first class mail, postage prepaid, at such holders’ address as the same appears on the records of the Partnership. Any notice which was transmitted or mailed in the manner herein provided shall be conclusively presumed to have been duly given on the date received by the holder. Each such notice shall state, as appropriate: (1) the date of conversion, which date may be any date within one business day following the date on which the notice is transmitted or mailed; (2) the number of units of Class Six Partnership Preferred Units to be converted and, if fewer than all such units held by such holder are to be converted, the number of such units to be converted; and (3) the then current Conversion Price. Upon receiving such notice of conversion, each such holder shall promptly surrender the certificates representing such Class Six Partnership Preferred Units as are being converted on the conversion date, duly endorsed or assigned to the Partnership or in blank, at the office of the Transfer Agent; provided, however, that the failure to so surrender any such certificates shall not in any way affect the validity of the conversion of the underlying Class Six Partnership Preferred Units into Partnership Common Units.

(b)    (iii) Unless the Partnership Common Units issuable on conversion are to be issued in the same name as the name in which such Class Six Partnership Preferred Units are registered, each such unit surrendered following conversion shall be accompanied by instruments of transfer, in form satisfactory to the Partnership, duly executed by the holder or such holder’s duly authorized representative, and an amount sufficient to pay any transfer or similar tax (or evidence reasonably satisfactory to the Partnership demonstrating that such taxes have been paid).

(2)    A holder of Class Six Partnership Preferred Units shall, as of the date of the conversion of such units to Partnership Common Units, be entitled to receive a cash payment in respect of any distributions (whether or not earned or declared) that are accumulated, accrued and unpaid thereon as of the time of such conversion, provided, however, that payment in respect of any distributions on such units that has been declared but for which the Distribution Payment Date has not yet been reached shall be payable as of such Distribution Payment Date. Except as provided above, the Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on converted units.

(i)    As promptly as practicable after the surrender of certificates for Class Six Partnership Preferred Units as aforesaid, and in any event no later than three business days after the date of such surrender, the Partnership shall issue and deliver at such office to such holder, or send on such holders’ written order, a

11

certificate or certificates for the number of full Partnership Common Units issuable upon the conversion of such Class Six Partnership Preferred Units in accordance with the provisions of this Section 7, and any fractional interest in respect of a Partnership Common Unit arising upon such conversion shall be settled as provided in paragraph (c) of this Section 7.

(ii)    Each conversion shall be deemed to have been effected (x) in the case of a conversion pursuant to subparagraph (a)(i) of this Section 7 immediately prior to the close of business on the date on which the certificates for Class Six Partnership Preferred Units shall have been surrendered and such notice received by the Partnership as provided in subparagraph (a)(i) of this Section 7, and (y) in the case of a conversion pursuant to subparagraph (a)(ii) of this Section 7, immediately prior to the close of business on the date identified as the conversion date in the notice of conversion sent by the Partnership pursuant to subparagraph (a)(ii) of this Section 7; and, in the case of (x) or (y), the person or persons in whose name or names any certificate or certificates for Partnership Common Units shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the units represented thereby at such time on such date, and such conversion shall be at the Conversion Price in effect at such time on such date, unless the transfer books of the Partnership shall be closed on that date, in which event such person or persons shall be deemed to become such holder or holders of record at the close of business on the next succeeding day on which such transfer books are open, but such conversion shall be at the Conversion Price in effect on the date in the notice of conversion sent by the Partnership as aforesaid.

ii)     No fractional Partnership Common Units or scrip representing fractions of a Partnership Common Unit shall be issued upon conversion of the Class Six Partnership Preferred Units. Instead of any fractional interest in a Partnership Common Unit that would otherwise be deliverable upon the conversion of Class Six Partnership Preferred Units, the Partnership shall pay to the holder of such units an amount of cash equal to the product of (i) such fraction and (ii) the value of a REIT Share as of the date of conversion. If more than one of any holder’s units shall be converted at one time, the number of full Partnership Common Units issuable upon conversion thereof shall be computed on the basis of the aggregate number of Class Six Partnership Preferred Units so converted.

(c)    If the Partnership shall be a party to any transaction (including with limitation a merger, consolidation, statutory exchange, sale of all or substantially all of the Partnership’s assets or recapitalization of the Partnership Common Units, but excluding any transaction as to which a charge in the Adjustment Factor would be effected) (each of the foregoing being referred to herein as a “Transaction”), in each case, as a result of which Partnership Common Units shall be converted into the right to receive securities or other property (including cash or any combination thereof), each Class Six Partnership Preferred Unit which is not converted into the right to receive securities or other property in connection with such Transaction shall thereupon be convertible into the kind and amount of securities and other property (including cash or any combination thereof) receivable upon such consummation by a holder of that number of Partnership Common Units into which Class Six Partnership Preferred Units were convertible immediately prior to such Transaction. The Partnership shall not be a party to any transaction unless the terms of such Transaction are consistent with the provisions of this paragraph (d), and it shall not consent or agree to the occurrence of any Transaction until the Partnership has entered into an agreement with the successor or purchasing entity, as the case may be, for the benefit of the holders of the Class Six Partnership Preferred Units that will contain provisions enabling the holders of the Class Six Partnership Preferred Units that remain outstanding after such Transaction to convert into the consideration received by holders of Partnership Common Units at the Conversion Price in effect immediately prior to such Transaction. The provisions of this Paragraph (d) shall apply to successive Transactions.

(d)    Whenever the Conversion Price is adjusted as herein provided (whether pursuant to paragraph (d) of this Section 7 or as a result of a change in the Adjustment Factor), the General Partner shall promptly file with the Transfer Agent an officer’s certificate setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment which certificate shall be conclusive evidence of the correctness of such adjustment absent manifest error. Promptly after delivery of such certificate, the General

12

Partner shall prepare a notice of such adjustment of the Conversion Price setting forth the adjusted Conversion Price and the effective date such adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Price to each holder of Class Six Partnership Preferred Units at such holder’s address as shown on the records of the Partnership.

(e)    In any case in which an adjustment to the Adjustment Factor shall become effective immediately after the effective date of an event, retroactive to the record date, if any, for such event, the Partnership may defer until the occurrence of such event (A) issuing to the holder of any Class Six Partnership Preferred Units converted after such record date and before the occurrence of such event the additional Partnership Common Units issuable upon such conversion by reason of the adjustment required by such event over and above the Partnership Common Units issuable upon such conversion before giving effect to such adjustment and (B) paying to such holder any amount of cash in lieu of any fraction pursuant to Section 7(c).

(f)    There shall be no adjustment of the Conversion Price in case of the issuance of any unit of the Partnership except as specifically set forth in the definition of “Adjustment Factor” or in this Section 7. In addition, notwithstanding any other provision contained in the definition of “Adjustment Factor” or in this Section 7, there shall be no adjustment of the Conversion Price upon the payment of any cash distributions on any units of the Partnership.

(g)    If the Partnership shall take any action affecting the Partnership Common Units, other than action described in the definition of “Adjustment Factor” or in this Section 7 that, in the opinion of the General Partner would materially adversely affect the conversion rights of the holders of Class Six Partnership Preferred Units, the Conversion Price for the Class Six Partnership Preferred Units may be adjusted, to the extent permitted by law in such manner, if any, and at such time as the General Partner, in its sole discretion, may determine to be equitable under the circumstances.

(h)    The Partnership will pay any and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of Partnership Common Units or other securities or property on conversion of Class Six Partnership Preferred Units pursuant hereto; provided, however, that the Partnership shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue or delivery of Partnership Common Units or other securities or property in a name other than that of the holder of the Class Six Partnership Preferred Units to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Partnership the amount of any such tax or established, to the reasonable satisfaction of the Partnership, that such tax has been paid.

(i)    In addition to any other adjustment required hereby, to the extent permitted by law, the Partnership from time to time may decrease the Conversion Price by any amount, permanently or for a period of at least twenty Business Days, if the decrease is irrevocable during the period.

(j)    For purposes of the definition of “Twelve-Month Period” in the Agreement, any holder of Class Six Partnership Preferred Units that have been converted to Partnership Common Units shall be deemed to have acquired such Partnership Common Units when such Class Six Partnership Units were acquired.

8.    Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

9.    General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Preferred Units.

13

10.    Allocations of Income and Loss.

For each taxable year, each holder of Preferred Units will be allocated a portion of the Net Income and Net Loss of the Partnership equal to the portion of the Net Income and Net Loss of the Partnership that would be allocated to such holder pursuant to Article 6 of the Agreement if such holder held a number of Partnership Common Units equal to (i) the number of Preferred Units held by such holder, multiplied by (ii) 0.5. Upon liquidation, dissolution or winding up of the Partnership, the Partnership shall endeavor to allocate income and gain to the holders of the Preferred Units such that the Capital Accounts related to the Preferred Units are equal to their Liquidation Preference.

11.    Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. As long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership Units, including, without limitation, any Partnership Units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to materially and adversely affect the rights or preferences of the holders of Preferred Units. With respect to the exercise of the above-described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

12.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer applicable to Common Units, as set forth in the Agreement.

3. Ranking.

Any class or series of Partnership Units of the Partnership shall be deemed to rank:

(a)    prior or senior to the Class Seven Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class Seven Partnership Preferred Units (the partnership units being hereinafter referred to, collectively, as “Senior Partnership Units”);

(b)    on a parity with the Class Seven Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class Seven Partnership Preferred Units (i) if such class or series of partnership units shall be Class G Partnership Preferred Units, Class One Partnership Preferred Units, Class Two Partnership Preferred Units, Class Three Partnership Preferred Units, Class Four Partnership Preferred Units or Class Six Partnership Preferred Units or (ii) if the holders of such class or series of partnership units and the Class Seven Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the partnership units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class Seven Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, (i) if such class or series of partnership units shall be Partnership Common Units, Class I High Performance Partnership Units or Class Five Partnership Preferred Units or (ii) if the holders of Class Seven Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the partnership units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

4. Quarterly Cash Distributions.

(a)    The “Quarterly Distribution Amount,” as of any date, shall be equal to (i) the Distribution Rate then in effect, multiplied by (ii) $25, and divided by (iii) four. Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner, quarterly cash distributions in an amount per Preferred Unit equal to the Quarterly Distribution Amount in effect as of the date such distribution is declared by the General Partner, and no more. On each Reset Date, the Distribution Rate thereafter in effect shall be adjusted by the General Partner to equal the lesser of (i) the Distribution Rate in effect immediately prior to such Reset Date or (ii) the Dividend Yield of the class of Qualifying Preferred Stock most recently issued by the Previous General Partner or, if there is no class of Qualifying Preferred Stock of the Previous General Partner outstanding as of any Reset Date, the Weighted Average of Preferred Stock Dividend Yields, calculated as of the end of the calendar quarter immediately preceding such Reset Date; provided, further, that if for any reason there are no classes of Qualifying Preferred Stock of the type described in the definition of “Weighted Average of Preferred Stock Dividend Yields” outstanding on any Reset Date and the reference to the Weighted Average of Preferred Stock Dividend Yields would otherwise be determinative of the calculation of the adjusted Distribution Rate on such Reset Date, the adjusted Distribution Rate for the succeeding five (5) year period shall be the Distribution Rate in effect immediately prior to such Reset Date. Upon any such adjustment of the Distribution Rate, the General Partner shall send a notice describing such adjustment to the holders of the Preferred Units at their respective addresses, as set forth on Exhibit A to the Agreement.

4

(b)    Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. If the Preferred Units are issued other than on a record date for the payment of distributions to the holders of Preferred Units, the Quarterly Distribution Amount shall, for any quarter in which the Distribution Rate changes on any Reset Date, be appropriately prorated based on the portions of such quarter during which the different Distribution Rates were in effect, on the basis of twelve 30-day months and a 360-day year. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

(c)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(d)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(e)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5

5. Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to the extent necessary to enable them to receive a liquidation preference (the “Liquidation Preference”) per Preferred Unit equal to the sum of (i) $25 plus (ii) any accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders will not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following appropriate allocations of Partnership income, gain, deduction and loss, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to the extent necessary to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6. Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (such Preferred Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for REIT Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for REIT Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such REIT Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for Federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in

6

exchange for REIT Shares. In making such election to cause the Previous General Partner to acquire Tendered Units, the Partnership shall act in a fair, equitable and reasonable manner that neither prefers one group or class of Tendering Parties over another nor discriminates against a group or class of Tendering Parties. If the Partnership elects to redeem any number of Tendered Units for REIT Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of REIT Shares equal to the REIT Shares Amount for such number of the Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The REIT Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible REIT Shares, free of any pledge, lien, encumbrance or restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such REIT Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such REIT Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. REIT Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street Parkway, Suites 1100, Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for REIT Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public

7

offering (a “Public Offering Funding”) by the Previous General Partner of a number of REIT Shares (“Registrable Shares”) equal to the REIT Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for REIT Shares if such exchange would be prohibited under the Charter.

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Preferred Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of an equal number of Partnership Common Units. Any Preferred Units so contributed to the Special Limited PartnerPartners shall be converted into Partnership Common Units.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    No Tendering Party may (a) effect a Redemption more than once in any fiscal quarter of a Twelve-Month Period or (b) effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its shareholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner

8

desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a shareholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of REIT Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(1) or (b) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specific Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver REIT Shares for the Preferred Units evidenced thereby. From and after the Specific Redemption Date (i) distributions with respect to the Preferred Units shall

9

cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or REIT Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties (i) shall not be entitled to elect or effect a Redemption where the Redemption would consist of less than all the Preferred Units held by Partners and, to the extent that the aggregate Percentage Interests of the Limited Partners would be reduced, as a result of the Redemption, to less than one percent (1%) and (ii) shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the date on which the aggregate Percentage Interests of the Limited Partners (other than the Special Limited PartnerPartners) are less than one percent (1%), the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Limited Partner Interests (other than the Special Limited Partner’sPartners’ Limited Partner Interest) by treating any Limited Partner as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such Limited Partner that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a Limited Partner pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such Limited Partner. For purposes of this Section 6(l), (a) any Limited Partner (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

7. Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8. General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto.

9. Allocations of Income and Loss.

Subject to the terms of Section 5 hereof, for each taxable year, (i) each holder of Preferred Units will be allocated, to the extent possible, net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (ii) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other interests in the Partnership.

10

10. Voting Rights.

Except as otherwise required by applicable law or in the Agreement, the holders of the Preferred Units will have the same voting rights as holders of the Partnership Common Units. As long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of the Partnership Unit Designation of the Preferred Units that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership units, including, without limitation, any Partnership units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. With respect to the exercise of the above described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

11. Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer as are, and the holders of Preferred Units shall be entitled to the same rights of transfer as are, applicable to Common Units as set forth in the Agreement.

PARTNERSHIP UNIT DESIGNATION OF THE

CLASS A PARTNERSHIP PREFERRED UNITS

OF AIMCO PROPERTIES, L.P.

1. Number of Units and Designation.

A class of Partnership Preferred Units is hereby designated as “Class A Partnership Preferred Units,” and the number of Partnership Preferred Units constituting such class shall be five million (5,000,000).

2. Definitions.

For purposes of the Class A Partnership Preferred Units, the following terms shall have the meanings indicated in this Section 2, and capitalized terms used and not otherwise defined herein shall have the meanings assigned thereto in the Agreement:

“Agreement” shall mean the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of July 29, 1994, amended and restated as of February 28, 2007, as amended.

“Alternative Form Consideration” shall have the meaning set forth in the Articles Supplementary for the Class A Preferred Stock.

“Class A Partnership Preferred Unit” means a Partnership Preferred Unit with the designations, preferences and relative, participating, optional or other special rights, powers and duties as are set forth in this Exhibit Y. It is the intention of the General Partner that each Class A Partnership Preferred Unit shall be substantially the economic equivalent of one share of Class A Preferred Stock.

“Class A Preferred Stock” means the Class A Cumulative Preferred Stock, par value $.01 per share, of the Previous General Partner.

“Code” shall mean the Internal Revenue Code of 1986, as amended from time to time, or any successor statute thereto. Reference to any provision of the Code shall mean such provision as in effect from time to time, as the same may be amended, and any successor thereto, as interpreted by any applicable regulations or other administrative pronouncements as in effect from time to time.

“Common Stock” shall mean the Class A Common Stock, par value $.01 per share, of the Previous General Partner.

“Distribution Payment Date” shall mean any date on which cash dividends are paid on outstanding shares of the Class A Preferred Stock.

“Distribution Record Date” shall have the meaning set forth in Section 3 of this Exhibit Y.

“Junior Partnership Units” shall have the meaning set forth in paragraph (c) of Section 7 of this Exhibit Y.

“Parity Partnership Units” shall have the meaning set forth in paragraph (b) of Section 7 of this Exhibit Y.

“Partnership” shall mean AIMCO Properties, L.P., a Delaware limited partnership.

“Senior Partnership Units” shall have the meaning set forth in paragraph (a) of Section 7 of this Exhibit Y.

1

3. Distributions.

On every Distribution Payment Date, the holders of Class A Partnership Preferred Units shall be entitled to receive distributions payable in cash in an amount per Class A Partnership Preferred Unit equal to the per share dividend payable on the Class A Preferred Stock on such Distribution Payment Date. Each such distribution shall be payable to the holders of record of the Class A Partnership Preferred Units, as they appear on the records of the Partnership at the close of business on the record date (the “Distribution Record Date”) for the dividend payable with respect to the Class A Preferred Stock on such Distribution Payment Date. Holders of Class A Partnership Preferred Units shall not be entitled to any distributions on the Class A Partnership Preferred Units, whether payable in cash, property or stock, except as provided herein.

4. Liquidation Preference.

(a)    In the event of any liquidation, dissolution or winding up of the Partnership, whether voluntary or involuntary, before any payment or distribution of the Partnership (whether capital, surplus or otherwise) shall be made to or set apart for the holders of Junior Partnership Units, the holders of Class A Partnership Preferred Units shall be entitled to receive Twenty-Five Dollars ($25.00) per Class A Partnership Preferred Unit (the “Liquidation Preference”), plus an amount per Class A Partnership Preferred Unit equal to all dividends (whether or not declared or earned) accumulated, accrued and unpaid on one share of Class A Preferred Stock to the date of final distribution to such holders; but such holders shall not be entitled to any further payment. Until the holders of the Class A Partnership Preferred Units have been paid the Liquidation Preference in full, plus an amount equal to all dividends (whether or not declared or earned) accumulated, accrued and unpaid on the Class A Preferred Stock to the date of final distribution to such holders, no payment shall be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership. If, upon any liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Class A Partnership Preferred Units shall be insufficient to pay in full the preferential amount aforesaid and liquidating payments on any Parity Partnership Units, then such assets, or the proceeds thereof, shall be distributed among the holders of Class A Partnership Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Class A Partnership Preferred Units and any such other Parity Partnership Units if all amounts payable thereon were paid in full. For the purposes of this Section 4, (i) a consolidation or merger of the Partnership with one or more partnerships, or (ii) a sale or transfer of all or substantially all of the Partnership’s assets shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Partnership.

(b)    Upon any liquidation, dissolution or winding up of the Partnership, after payment shall have been made in full to the holders of Class A Partnership Preferred Units and any Parity Partnership Units, as provided in this Section 4, any other series or class or classes of Junior Partnership Units shall, subject to the respective terms thereof, be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Class A Partnership Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

5. Redemption.

Class A Partnership Preferred Units shall be redeemable by the Partnership as follows:

(a)    At any time that the Previous General Partner exercises its right to redeem all or any of the shares of Class A Preferred Stock, the General Partner shall cause the Partnership to redeem an equal number of Class A Partnership Preferred Units, at a redemption price per Class A Partnership Preferred Unit payable in cash and equal to the same price per share paid by the Previous General Partner to redeem the Class A Preferred Stock. In the event of a redemption of Class A Partnership Preferred Units, if the redemption date occurs after a dividend record date for the Class A Preferred Stock and on or prior to the related Distribution Payment Date, the distribution payable on such Distribution Payment Date in respect of such Class A Partnership Preferred Units called for redemption shall be payable on such Distribution Payment Date to the holders of record of such

2

Class A Partnership Preferred Units on the applicable dividend record date, and shall not be payable as part of the redemption price for such Class A Partnership Preferred Units.

(b)    If the Partnership shall redeem Class A Partnership Preferred Units pursuant to paragraph (a) of this Section 5, from and after the redemption date (unless the Partnership shall fail to make available the amount of cash necessary to effect such redemption), (i) except for payment of the redemption price, the Partnership shall not make any further distributions on the Class A Partnership Preferred Units so called for redemption, (ii) said units shall no longer be deemed to be outstanding, and (iii) all rights of the holders thereof as holders of Class A Partnership Preferred Units of the Partnership shall cease except the rights to receive the cash payable upon such redemption, without interest thereon; provided, however, that if the redemption date occurs after dividend record date for the Class A Preferred Stock and on or prior to the related Distribution Payment Date, the full distribution payable on such Distribution Payment Date in respect of such Class A Partnership Preferred Units called for redemption shall be payable on such Distribution Payment Date to the holders of record of such Class A Partnership Preferred Units on the applicable dividend record date notwithstanding the prior redemption of such Class A Partnership Preferred Units. No interest shall accrue for the benefit of the holders of the Class A Partnership Preferred Units to be redeemed on any cash set aside by the Partnership.

(c)    If fewer than all the outstanding Class A Partnership Preferred Units are to be redeemed, units to be redeemed shall be selected by the Partnership from outstanding Class A Partnership Preferred Units not previously called for redemption by any method determined by the General Partner in its discretion. Upon any such redemption, the General Partner shall amend Exhibit A to the Agreement as appropriate to reflect such redemption.

6. Status of Reacquired Units.

All Class A Partnership Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled.

7. Conversion.

Class A Partnership Preferred Units shall be convertible as follows:

(a)    Upon any conversion of shares of Class A Preferred Stock into shares of Common Stock, a number of Class A Partnership Preferred Units equal to the number of shares of Class A Preferred Stock so converted shall be automatically converted into a number of Partnership Common Units equal to the number of shares of Common Stock issuable with respect to the shares of Class A Preferred Stock so converted. Upon any conversion of shares of Class A Preferred Stock into Alternative Form Consideration, a number of Class A Partnership Preferred Units equal to the number of shares of Class A Preferred Stock so converted shall be automatically converted into the same type and amount of Alternative Form Consideration as is deliverable with respect to the shares of Class A Preferred Stock so converted. Each conversion of Class A Partnership Preferred Units shall be deemed to have been effected at the same date and time as the corresponding conversion of Class A Preferred Stock.

(b)    Holders of Class A Partnership Preferred Units at the close of business on a Distribution Record Date shall be entitled to receive the distribution payable on such units on the corresponding Distribution Payment Date notwithstanding the conversion thereof after such Distribution Record Date and on or prior to such Distribution Payment Date.

(c)    If, upon any conversion of Class A Preferred Stock, the Previous General Partner is required to make a cash payment in lieu of issuing any fractional shares of Common Stock, then, in connection with the corresponding conversion of Class A Partnership Preferred Units, the Partnership shall make an equal cash payment to the holder of such converted Class A Partnership Preferred Units.

3

(d)    The Partnership will pay any and all documentary stamp or similar issue or transfer taxes payable in respect of (i) the issue or delivery of Partnership Common Units or other securities or property on conversion of Class A Partnership Preferred Units pursuant hereto, and (ii) the issue or delivery of Common Stock or other securities or property on conversion of Class A Preferred Stock pursuant to the terms hereof.

8. Ranking.

Any class or series of Partnership Units of the Partnership shall be deemed to rank:

(a)    prior or senior to the Class A Partnership Preferred Units, as to the payment of distributions and as to distributions of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class A Partnership Preferred Units (“Senior Partnership Units”);

(b)    on a parity with the Class A Partnership Preferred Units, as to the payment of distributions and as to distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class A Partnership Preferred Units if (i) such class or series of Partnership Units shall be Class Z Partnership Preferred Units, Series A Community Reinvestment Act Perpetual Partnership Preferred Units, Class One Partnership Preferred Units, Class Two Partnership Preferred Units, Class Three Partnership Preferred Units, Class Four Partnership Preferred Units, Class Six Partnership Preferred Units or Class Seven Partnership Preferred Units, or (ii) the holders of such class or series of Partnership Units and the Class A Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class A Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if (i) such class or series of Partnership Units shall be Partnership Common Units or Class I High Performance Partnership Units, or (ii) the holders of Class A Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the Partnership Units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

9. Special Allocations.

(a)    Gross income and, if necessary, gain shall be allocated to the holders of Class A Partnership Preferred Units for any Fiscal Year (and, if necessary, subsequent Fiscal Years) to the extent that the holders of Class A Partnership Preferred Units receive a distribution on any Class A Partnership Preferred Units (other than an amount included in any redemption pursuant to Section 5 hereof) with respect to such Fiscal Year.

(b)    If any Class A Partnership Preferred Units are redeemed pursuant to Section 5 hereof, for the Fiscal Year that includes such redemption (and, if necessary, for subsequent Fiscal Years) (a) gross income and gain (in such relative proportions as the General Partner in its discretion shall determine) shall be allocated to the holders of Class A Partnership Preferred Units to the extent that the redemption amounts paid or payable with respect to the Class A Partnership Preferred Units so redeemed exceeds the aggregate Capital Contributions (net of liabilities assumed or taken subject to by the Partnership) per Class A Partnership Preferred Unit allocable to the Class A Partnership Preferred Units so redeemed and (b) deductions and losses (in such relative proportions as the General Partner in its discretion shall determine) shall be allocated to the holders of Class A Partnership

In addition, nothing contained herein shall be deemed to limit or otherwise restrict the authority of the General Partner or the Special Limited PartnerPartners under the Agreement, other than in their capacity as holders of the Class A Partnership Preferred Units.

3. Ranking.

Any class or series of Partnership Units of the Partnership shall be deemed to rank:

(a)    prior or senior to the Class Nine Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, if the holders of such class or series shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of Class Nine Partnership Preferred Units (the partnership units being hereinafter referred to, collectively, as “Senior Partnership Units”);

(b)    on a parity with the Class Nine Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class Nine Partnership Preferred Units (i) if such class or series of partnership units shall be Class A Partnership Preferred Units, Class Z Partnership Preferred Units, Series A Community Reinvestment Act Perpetual Partnership Preferred Units, Class One Partnership Preferred Units, Class Two Partnership Preferred Units, Class Three Partnership Preferred Units, or Class Four Partnership Preferred Units, or (ii) if the holders of such class or series of partnership units and the Class Nine Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the partnership units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

(c)    junior to the Class Nine Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, (i) if such class or series of partnership units shall be Partnership Common Units or Class I High Performance Partnership Units or (ii) if the holders of Class Nine Partnership Preferred Units shall be entitled to receipt of distributions or of amounts distributable upon liquidation, dissolution or winding up, as the case may be, in preference or priority to the holders of such class or series of Partnership Units (the partnership units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Junior Partnership Units”).

4. Quarterly Cash Distributions.

(a)    Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner out of Available Cash, quarterly cash distributions in an amount per Preferred Unit equal to $0.375, and no more.

(b)    Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

4

(c)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(d)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(e)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5. Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to the extent necessary to enable them to receive a liquidation preference (the “Liquidation Preference”) per Preferred Unit equal to the sum of (i) $25 plus (ii) any accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders will not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following appropriate allocations of Partnership income, gain, deduction and loss, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

5

(d)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to the extent necessary to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6. Redemption.

(a)    Except as set forth in Section 6(l) hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (such Preferred Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for Federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for Shares. If the Partnership elects to redeem any number of Tendered Units for Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for (x) in the case of REIT Shares, a number of REIT Shares equal to the REIT Shares Amount for such number of the Tendered Units, and (y) in the case of Class A Preferred Shares, a number of Class A Preferred Shares equal to the number of Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible Shares, free of any pledge, lien, encumbrance or restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any Shares owned or held by such Person, whether or not such Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such Shares for all purposes, including, without limitation, rights to vote or consent, receive dividends, and exercise rights, as of the Specified Redemption Date. Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

6

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street, Suite 11001700, Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    In the event that the Partnership declines to cause the Previous General Partner to acquire all of the Tendered Units from the Tendering Party in exchange for Shares pursuant to this Section 6 following receipt of a Notice of Redemption (a “Declination”):

(1)    The Previous General Partner or the General Partner shall give notice of such Declination to the Tendering Party on or before the close of business on the Cut-Off Date.

(2)    The Partnership may elect to raise funds for the payment of the Cash Amount either (a) by requiring that the Previous General Partner contribute such funds from the proceeds of a registered public offering (a “Public Offering Funding”) by the Previous General Partner of a number of REIT Shares (“Registrable Shares”) equal to the REIT Shares Amount with respect to the Tendered Units or (b) from any other sources (including, but not limited to, the sale of any Property and the incurrence of additional Debt) available to the Partnership.

(3)    Promptly upon the General Partner’s receipt of the Notice of Redemption and the Previous General Partner or the General Partner giving notice of the Partnership’s Declination, the General Partner shall give notice (a “Single Funding Notice”) to all Qualifying Parties then holding Preferred Units and having Redemption rights pursuant to this Section 6 and require that all such Qualifying Parties elect whether or not to effect a Redemption of their Preferred Units to be funded through such Public Offering Funding. In the event that any such Qualifying Party elects to effect such a Redemption, it shall give notice thereof and of the number of Preferred Units to be made subject thereon in writing to the General Partner within ten (10) Business Days after receipt of the Single Funding Notice, and such Qualifying Party shall be treated as a Tendering Party for all purposes of this Section 6. In the event that a Qualifying Party does not so elect, it shall be deemed to have waived its right to effect a Redemption for the next twelve months; provided, however, that the Previous General Partner shall not be required to acquire Preferred Units pursuant to this Section 6(f) more than twice within any twelve-month period.

Any proceeds from a Public Offering Funding that are in excess of the Cash Amount shall be for the sole benefit of the Previous General Partner and/or the General Partner. The General Partner and/or the Special Limited PartnerPartners shall make a Capital Contribution of such amounts to the Partnership for an additional General Partner Interest and/or Limited Partner Interest. Any such contribution shall entitle the General Partner and the Special Limited PartnerPartners , as the case may be, to an equitable Percentage Interest adjustment.

(g)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for Shares if such exchange would be prohibited under the Charter.

7

(h)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Preferred Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of an equal number of Partnership Common Units (or Class A Partnership Preferred Units in the case of a Redemption for Class A Preferred Shares). Any Preferred Units so contributed to the Special Limited PartnerPartners shall be converted into Partnership Common Units (or Class A Partnership Preferred Units in the case of a Redemption for Class A Preferred Shares).

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    No Tendering Party may (a) effect a Redemption more than once in any fiscal quarter of a Twelve-Month Period or (b) effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its stockholders of some or all of its portion of such Partnership distribution.

(4)    Notwithstanding anything herein to the contrary, with respect to any Redemption or acquisition of Tendered Units by the Previous General Partner pursuant to this Section 6, in the event that the Previous General Partner or the General Partner gives notice to all Limited Partners (but excluding any Assignees) then owning Partnership Interests (a “Primary Offering Notice”) that the Previous General Partner desires to effect a primary offering of its equity securities then, unless the Previous General Partner and the General Partner otherwise consent, commencement of the actions denoted in Section 6(f) hereof as to a Public Offering Funding with respect to any Notice of Redemption thereafter received, whether or not the Tendering Party is a Limited Partner, may be delayed until the earlier of (a) the completion of the primary offering or (b) ninety (90) days following the giving of the Primary Offering Notice.

(5)    Without the Consent of the Previous General Partner, no Tendering Party may effect a Redemption within ninety (90) days following the closing of any prior Public Offering Funding.

(6)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(7)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners ) and paid for, by the issuance of the Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a stockholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

8

(i)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (a) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (b) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares or other shares of the Previous General Partner in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (a) the actual and constructive ownership of REIT Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(1), or (b) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(j)    On or after the Specified Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver Shares for the Preferred Units evidenced thereby. From and after the Specified Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive Cash Amount and/or Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(k)    Notwithstanding the provisions of this Section 6, the Tendering Parties shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner hereunder.

(l)    Notwithstanding any other provision of the Agreement, on and after the third anniversary of the date of original issuance of the Preferred Units, the Partnership shall have the right, but not the obligation, from time to time and at any time to redeem any and all outstanding Preferred Units by treating any holder of Preferred Units as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for the amount of Preferred Units to be specified by the General Partner, in its sole and absolute discretion, by notice to such holder that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a holder of Preferred Units pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such holder. For purposes of this Section 6(l), (a) any holder of Preferred Units (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (b) the provisions of Sections 6(f)(1), 6(h)(2), 6(h)(3) and 6(h)(5) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

9

7. Conversion.

(a)    At any time and from time to time after the third anniversary of the date of initial issuance of the Preferred Units, the Partnership shall have the right, but not the obligation, to cause any Preferred Units to be converted into the number of Partnership Common Units obtained by multiplying the number of Preferred Units converted by the Conversion Ratio on the date provided for in subparagraph (b)(4) of this Section 7. In order to exercise the conversion right, the Partnership shall send notice of such conversion to each holder of record of Preferred Units to be converted. Such notice shall be provided by facsimile or, if facsimile is not available, then by first class mail, postage prepaid, at such holders’ address as the same appears on the records of the Partnership. Any notice which was transmitted or mailed in the manner herein provided shall be conclusively presumed to have been duly given on the date received by the holder. Each such notice shall state, as appropriate: (1) the date of conversion, which date may be any date within twenty (20) Business Days following the date on which the notice is transmitted or mailed; and (2) the number of units of Preferred Units to be converted and, if fewer than all such units held by such holder are to be converted, the number of such units to be converted. Upon receiving such notice of conversion, each such holder shall promptly surrender the certificates representing such Preferred Units as are being converted on the conversion date, duly endorsed or assigned to the Partnership or in blank, at the office of the Transfer Agent; provided, however, that the failure to so surrender any such certificates shall not in any way affect the validity of the conversion of the underlying Preferred Units into Partnership Common Units.

(b)     (i) The Partnership Common Units issuable on conversion shall be issued in the same name as the name in which such Preferred Units are registered.

(i)    The Partnership shall make no payment or allowance for unpaid distributions, whether or not in arrears, on converted units, except that a holder of Preferred Units that are converted shall be entitled to receive a cash payment on the Dividend Payment Date for any distribution on such units that has been declared and for which the record date precedes the conversion date.

(ii)    As promptly as practicable after the surrender of certificates for Preferred Units as aforesaid, and in any event no later than five (5) Business Days after the date of such surrender, the Partnership shall issue and deliver at such office to such holder, or send on such holders’ written order, a certificate or certificates for the number of full Partnership Common Units issuable upon the conversion of such Preferred Units in accordance with the provisions of this Section 7, and any fractional interest in respect of a Partnership Common Unit arising upon such conversion shall be settled as provided in paragraph (c) of this Section 7.

(iii)    Each conversion shall be deemed to have been effected immediately prior to the close of business on the date identified as the conversion date in the notice of conversion sent by the Partnership pursuant to subparagraph (a) of this Section 7; and the person or persons in whose name or names any certificate or certificates for Partnership Common Units shall be issuable upon such conversion shall be deemed to have become the holder or holders of record of the units represented thereby at such time on such date, and such conversion shall be at the Conversion Ratio in effect at such time on such date, unless the transfer books of the Partnership shall be closed on that date, in which event such person or persons shall be deemed to become such holder or holders of record at the close of business on the next succeeding day on which such transfer books are open, but such conversion shall be at the Conversion Ratio in effect on the date in the notice of conversion sent by the Partnership as aforesaid.

(c)    No fractional Partnership Common Units or scrip representing fractions of a Partnership Common Unit shall be issued upon conversion of the Preferred Units. Instead of any fractional interest in a Partnership Common Unit that would otherwise be deliverable upon the conversion of Preferred Units, the Partnership shall pay to the holder of such units an amount of cash equal to the product of (i) such fraction and (ii) the Market Value of a REIT Share as of the date of conversion. If more than one of any holder’s units shall be converted at one time, the number of full Partnership Common Units issuable upon conversion thereof shall be computed on the basis of the aggregate number of Preferred Units so converted.

10

(d)    If the Partnership shall be a party to any transaction (including with limitation a merger, consolidation, statutory exchange, sale of all or substantially all of the Partnership’s assets or recapitalization of the Partnership Common Units) (each of the foregoing being referred to herein as a “Transaction”), in each case, as a result of which Partnership Common Units shall be converted into the right to receive securities or other property (including cash or any combination thereof), each Preferred Unit which is not converted into the right to receive securities or other property in connection with such Transaction shall thereupon be convertible into the kind and amount of securities and other property (including cash or any combination thereof) receivable upon such consummation by a holder of that number of Partnership Common Units into which Preferred Units were convertible immediately prior to such Transaction. The provisions of this paragraph (d) shall apply to successive Transactions.

(e)    The Partnership will pay any and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of Partnership Common Units or other securities or property on conversion of Preferred Units pursuant hereto; provided, however, that the Partnership shall not be required to pay any tax that may be payable in respect of any transfer involved in the issue or delivery of Partnership Common Units or other securities or property in a name other than that of the holder of the Preferred Units to be converted, and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Partnership the amount of any such tax or established, to the reasonable satisfaction of the Partnership, that such tax has been paid.

(f)    For purposes of the definition of “Twelve-Month Period” in the Agreement, any holder of Preferred Units that have been converted to Partnership Common Units shall be deemed to have acquired such Partnership Common Units when such Units were acquired.

8. Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

9. General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Class Nine Partnership Preferred Units.

10. Allocations of Income and Loss.

Subject to the terms of Section 5 hereof, for each taxable year, (i) each holder of Preferred Units will be allocated, to the extent possible, net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (ii) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other interests in the Partnership.

11. Voting Rights.

The holders of the Preferred Units will not have any voting or approval rights, except (a) as required by applicable law or in the Agreement, and (b) as long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of this Partnership Unit Designation that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership units, including,

11

without limitation, any Partnership units that may have rights junior to, on a parity with, or senior or superior to the Preferred Units, will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. With respect to the exercise of the above described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

12. Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer as are, and the holders of Preferred Units shall be entitled to the same rights of transfer as are, applicable to Common Units as set forth in the Agreement.

(b)    on a parity with the Class Ten Partnership Preferred Units, as to the payment of distributions and as to the distribution of assets upon liquidation, dissolution or winding up, whether or not the distribution rates, distribution payment dates or redemption or liquidation prices per unit or other denomination thereof be different from those of the Class Ten Partnership Preferred Units (i) if such class or series of partnership units shall be Class A Partnership Preferred Units, Class Z Partnership Preferred Units, Series A Community Reinvestment Act Perpetual Partnership Preferred Units, Class One Partnership Preferred Units, Class Two Partnership Preferred Units, Class Three Partnership Preferred Units, Class Four Partnership Preferred Units, or Class Nine Partnership Preferred Units, or (ii) if the holders of such class or series of partnership units and the Class Ten Partnership Preferred Units shall be entitled to the receipt of distributions and of amounts distributable upon liquidation, dissolution or winding up in proportion to their respective amounts of accrued and unpaid distributions per unit or other denomination or liquidation preferences, without preference or priority one over the other (the partnership units referred to in clauses (i) and (ii) of this paragraph being hereinafter referred to, collectively, as “Parity Partnership Units”); and

4.    Quarterly Cash Distributions.

(a)    Holders of Preferred Units will be entitled to receive, when and as declared by the General Partner out of Available Cash, quarterly cash distributions in an amount per Preferred Unit equal to $0.375, and no more.

(b)    Any such distributions will be cumulative from the date of original issue, whether or not in any distribution period or periods such distributions have been declared, and shall be payable quarterly on February 15, May 15, August 15 and November 15 of each year (or, if not a Business Day, the next succeeding Business Day) (each a “Distribution Payment Date”), commencing on the first such date occurring after the date of original issue. If the Preferred Units are issued on any day other than a Distribution Payment Date, the first distribution payable on such Preferred Units will be prorated for the portion of the quarterly period that such Preferred Units are outstanding on the basis of twelve 30-day months and a 360-day year. Distributions will be payable in arrears to holders of record as they appear on the records of the Partnership at the close of business on the February 1, May 1, August 1 or November 1, as the case may be, immediately preceding each Distribution Payment Date. Holders of Preferred Units will not be entitled to receive any distributions in excess of cumulative distributions on the Preferred Units. No interest, or sum of money in lieu of interest, shall be payable in respect

3

of any distribution payment or payments on the Preferred Units that may be in arrears. Holders of any Preferred Units that are issued after the date of original issuance will be entitled to receive the same distributions as holders of any Preferred Units issued on the date of original issuance.

(c)    When distributions are not paid in full upon the Preferred Units or any Parity Partnership Units, or a sum sufficient for such payment is not set apart, all distributions declared upon the Preferred Units and any Parity Partnership Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Preferred Units and accumulated and unpaid on such Parity Partnership Units. Except as set forth in the preceding sentence, unless distributions on the Preferred Units equal to the full amount of accumulated and unpaid distributions have been or contemporaneously are declared and paid, or declared and a sum sufficient for the payment thereof has been or contemporaneously is set apart for such payment, for all past distribution periods, no distributions shall be declared or paid or set apart for payment by the Partnership with respect to any Parity Partnership Units.

(d)    Unless full cumulative distributions (including all accumulated, accrued and unpaid distributions) on the Preferred Units have been declared and paid, or declared and set apart for payment, for all past distribution periods, no distributions (other than distributions paid in Junior Partnership Units or options, warrants or rights to subscribe for or purchase Junior Partnership Units) may be declared or paid or set apart for payment by the Partnership and no other distribution of cash or other property may be declared or made, directly or indirectly, by the Partnership with respect to any Junior Partnership Units, nor shall any Junior Partnership Units be redeemed, purchased or otherwise acquired (except for a redemption, purchase or other acquisition of Partnership Common Units made for purposes of an employee incentive or benefit plan of the Partnership or any affiliate thereof, including, without limitation, Previous General Partner and its affiliates) for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such Junior Partnership Units), directly or indirectly, by the Partnership (except by conversion into or exchange for Junior Partnership Units, or options, warrants or rights to subscribe for or purchase Junior Partnership Units), nor shall any other cash or other property be paid or distributed to or for the benefit of holders of Junior Partnership Units.

(e)    Notwithstanding the foregoing provisions of this Section 4, the Partnership shall not be prohibited from (i) declaring or paying or setting apart for payment any distribution on any Parity Partnership Units or (ii) redeeming, purchasing or otherwise acquiring any Parity Partnership Units, in each case, if such declaration, payment, redemption, purchase or other acquisition is necessary to maintain the Previous General Partner’s qualification as a REIT.

5.    Liquidation Preference.

(a)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, before any allocation of income or gain by the Partnership shall be made to or set apart for the holders of any Junior Partnership Units, to the extent possible, the holders of Preferred Units shall be entitled to be allocated income and gain to the extent necessary to enable them to receive a liquidation preference (the “Liquidation Preference”) per Preferred Unit equal to the sum of (i) $25 plus (ii) any accumulated, accrued and unpaid distributions (whether or not earned or declared) to the date of final distribution to such holders; but such holders will not be entitled to any further payment or allocation. Until all holders of the Preferred Units have been paid the Liquidation Preference in full, no allocation of income or gain will be made to any holder of Junior Partnership Units upon the liquidation, dissolution or winding up of the Partnership.

(b)    If, upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, the assets of the Partnership, or proceeds thereof, distributable among the holders of Preferred Units shall be insufficient to pay in full the Liquidation Preference and liquidating payments on any Parity Partnership Units, then following appropriate allocations of Partnership income, gain, deduction and loss, such assets, or the proceeds thereof, shall be distributed among the holders of Preferred Units and any such Parity Partnership Units ratably in the same proportion as the respective amounts that would be payable on such Preferred Units and any such Parity Partnership Units if all amounts payable thereon were paid in full.

4

(c)    A voluntary or involuntary liquidation, dissolution or winding up of the Partnership will not include a consolidation or merger of the Partnership with one or more partnerships, corporations or other entities, or a sale or transfer of all or substantially all of the Partnership’s assets.

(d)    Upon any voluntary or involuntary liquidation, dissolution or winding up of the Partnership, after all allocations shall have been made in full to the holders of Preferred Units and any Parity Partnership Units to the extent necessary to enable them to receive their respective liquidation preferences, any Junior Partnership Units shall be entitled to receive any and all assets remaining to be paid or distributed, and the holders of the Preferred Units and any Parity Partnership Units shall not be entitled to share therein.

6.    Redemption.

(a)    Except as set forth in this Section 6 hereof, the Preferred Units may not be redeemed at the option of the Partnership, and will not be required to be redeemed or repurchased by the Partnership or the Previous General Partner except if a holder of a Preferred Unit effects a Redemption, as provided for in Section 6(b) hereof. The Partnership or the Previous General Partner may purchase Preferred Units from time to time in the open market, by tender or exchange offer, in privately negotiated purchases or otherwise.

(b)    On or after the first (1st) anniversary of becoming a holder of Preferred Units, a Qualifying Party shall have the right (subject to the terms and conditions set forth herein) to require the Partnership to redeem all or a portion of the Preferred Units held by such Qualifying Party (such Preferred Units being hereafter “Tendered Units”) in exchange (a “Redemption”) for REIT Shares issuable on, or the Cash Amount payable on, the Specified Redemption Date, as determined by the Partnership in its sole discretion. Any Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the Qualifying Party when exercising the Redemption right (the “Tendering Party”).

(c)    If the Partnership elects to redeem Tendered Units for REIT Shares rather than cash, then the Partnership shall direct the Previous General Partner to issue and deliver such REIT Shares to the Tendering Party pursuant to the terms set forth in this Section 6, in which case, (i) the Previous General Partner, acting as a distinct legal entity, shall assume directly the obligation with respect thereto and shall satisfy the Tendering Party’s exercise of its Redemption right, and (ii) such transaction shall be treated, for Federal income tax purposes, as a transfer by the Tendering Party of such Tendered Units to the Previous General Partner in exchange for REIT Shares. If the Partnership elects to redeem any number of Tendered Units for REIT Shares, rather than cash, on the Specified Redemption Date, the Tendering Party shall sell such number of the Tendered Units to the Previous General Partner in exchange for a number of REIT Shares equal to the REIT Shares Amount for such number of the Tendered Units. The Tendering Party shall submit (i) such information, certification or affidavit as the Previous General Partner may reasonably require in connection with the application of the Ownership Limit and other restrictions and limitations of the Charter to any such acquisition and (ii) such written representations, investment letters, legal opinions or other instruments necessary, in the Previous General Partner’s view, to effect compliance with the Securities Act. The REIT Shares shall be delivered by the Previous General Partner as duly authorized, validly issued, fully paid and accessible REIT Shares, free of any pledge, lien, encumbrance or restriction, other than the Ownership Limit and other restrictions provided in the Charter, the Bylaws of the Previous General Partner, the Securities Act and relevant state securities or “blue sky” laws. Neither any Tendering Party whose Tendered Units are acquired by the Previous General Partner pursuant to this Section 6, any Partner, any Assignee nor any other interested Person shall have any right to require or cause the Previous General Partner or the General Partner to register, qualify or list any REIT Shares owned or held by such Person, whether or not such REIT Shares are issued pursuant to this Section 6, with the SEC, with any state securities commissioner, department or agency, under the Securities Act or the Exchange Act or with any stock exchange; provided, however, that this limitation shall not be in derogation of any registration or similar rights granted pursuant to any other written agreement between the Previous General Partner and any such Person. Notwithstanding any delay in such delivery, the Tendering Party shall be deemed the owner of such REIT Shares for all purposes, including, without limitation, rights to vote or

5

consent, receive dividends, and exercise rights, as of the Specified Redemption Date. REIT Shares issued upon an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6 may contain such legends regarding restrictions under the Securities Act and applicable state securities laws as the Previous General Partner in good faith determines to be necessary or advisable in order to ensure compliance with such laws.

(d)    The Partnership shall have no obligation to effect any redemption unless and until a Tendering Party has given the Partnership a Notice of Redemption. Each Notice of Redemption shall be sent by hand delivery or by first class mail, postage prepaid, to AIMCO Properties, L.P., c/o AIMCO-GP, Inc., 4582 South Ulster Street, Suite 11001700, Denver, Colorado 80237, Attention: Investor Relations, or to such other address as the Partnership shall specify in writing by delivery to the holders of the Preferred Units in the same manner as that set forth above for delivery of the Notice of Redemption. At any time prior to the Specified Redemption Date for any Redemption, any holder may revoke its Notice of Redemption.

(e)    A Tendering Party shall have no right to receive distributions with respect to any Tendered Units (other than the Cash Amount) paid after delivery of the Notice of Redemption, whether or not the record date for such distribution precedes or coincides with such delivery of the Notice of Redemption. If the Partnership elects to redeem any number of Tendered Units for cash, the Cash Amount for such number of Tendered Units shall be delivered as a certified check payable to the Tendering Party or, in the General Partner’s sole and absolute discretion, in immediately available funds.

(f)    Notwithstanding the provisions of this Section 6, the Previous General Partner shall not, under any circumstances, elect to acquire Tendered Units in exchange for REIT Shares if such exchange would be prohibited under the Charter.

(g)    Notwithstanding anything herein to the contrary, with respect to any Redemption pursuant to this Section 6:

(1)    All Preferred Units acquired by the Previous General Partner for REIT Shares pursuant to this Section 6 hereof shall be contributed by the Previous General Partner to eitherany or bothall of the General Partner and the Special Limited PartnerPartners in such proportions as the Previous General Partner, the General Partner and the Special Limited PartnerPartners shall determine. Any Preferred Units so contributed to the General Partner shall automatically, and without further action required, be converted into and deemed to be a General Partner Interest comprised of number of Partnership Common Units equal to the number of REIT Shares issued in exchange for such Preferred Units. Any Preferred Units so contributed to the Special Limited PartnerPartners shall automatically, and without further action required, be converted into a number of Partnership Common Units equal to the number of REIT Shares issued in exchange for such Preferred Units.

(2)    Subject to the Ownership Limit, no Tendering Party may effect a Redemption for less than five hundred (500) Preferred Units or, if such Tendering Party holds (as a Limited Partner or, economically, as an Assignee) less than five hundred (500) Preferred Units, all of the Preferred Units held by such Tendering Party.

(3)    No Tendering Party may (A) effect a Redemption more than once in any fiscal quarter of a Twelve-Month Period or (B) effect a Redemption during the period after the Partnership Record Date with respect to a distribution and before the record date established by the Previous General Partner for a distribution to its stockholders of some or all of its portion of such Partnership distribution.

(4)    The consummation of such Redemption shall be subject to the expiration or termination of the applicable waiting period, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

(5)    The Tendering Party shall continue to own (subject, in the case of an Assignee, to the provision of Section 11.5 of the Agreement) all Preferred Units subject to any Redemption, and be treated as a

6

Limited Partner or an Assignee, as applicable, with respect to such Preferred Units for all purposes of the Agreement, until such Preferred Units are either paid for by the Partnership pursuant to this Section 6 or transferred to the Previous General Partner (or directly to the General Partner or Special Limited PartnerPartners) and paid for, by the issuance of REIT Shares, pursuant to this Section 6 on the Specified Redemption Date. Until a Specified Redemption Date and an acquisition of the Tendered Units by the Previous General Partner pursuant to this Section 6, the Tendering Party shall have no rights as a stockholder of the Previous General Partner with respect to the REIT Shares issuable in connection with such acquisition.

For purposes of determining compliance with the restrictions set forth in this Section 6(h), all Partnership Common Units and Partnership Preferred Units, including Preferred Units, beneficially owned by a Related Party of a Tendering Party shall be considered to be owned or held by such Tendering Party.

(h)    In connection with an exercise of Redemption rights pursuant to this Section 6, the Tendering Party shall submit the following to the General Partner, in addition to the Notice of Redemption:

(1)    A written affidavit, dated the same date as the Notice of Redemption, (A) disclosing the actual and constructive ownership, as determined for purposes of Code Sections 856(a)(6) and 856(h), of REIT Shares and any other classes or shares of the Previous General Partner by (i) such Tendering Party and (ii) any Related Party and (B) representing that, after giving effect to the Redemption, neither the Tendering Party nor any Related Party will own REIT Shares or other shares of the Previous General Partner in excess of the Ownership Limit;

(2)    A written representation that neither the Tendering Party nor any Related Party has any intention to acquire any additional REIT Shares or any other class of shares of the Previous General Partner prior to the closing of the Redemption on the Specified Redemption Date; and

(3)    An undertaking to certify, at and as a condition to the closing of the Redemption on the Specified Redemption Date, that either (A) the actual and constructive ownership of REIT Shares or any other class of shares of the Previous General Partner by the Tendering Party and any Related Party remain unchanged from that disclosed in the affidavit required by Section 6(i)(1), or (B) after giving effect to the Redemption, neither the Tendering Party nor any Related Party shall own REIT Shares or other shares of the Previous General Partner in violation of the Ownership Limit.

(i)    On or after the Specified Redemption Date, each holder of Preferred Units shall surrender to the Partnership the certificate evidencing such holder’s Preferred Units, at the address to which a Notice of Redemption is required to be sent. Upon such surrender of a certificate, the Partnership shall thereupon pay the former holder thereof the applicable Cash Amount and/or deliver REIT Shares for the Preferred Units evidenced thereby. From and after the Specified Redemption Date (i) distributions with respect to the Preferred Units shall cease to accumulate, (ii) the Preferred Units shall no longer be deemed outstanding, (iii) the holders thereof shall cease to be Partners to the extent of their interest in such Preferred Units, and (iv) all rights whatsoever with respect to the Preferred Units shall terminate, except the right of the holders of the Preferred Units to receive the Cash Amount and/or REIT Shares therefor, without interest or any sum of money in lieu of interest thereon, upon surrender of their certificates therefor.

(j)    Notwithstanding the provisions of this Section 6, the Tendering Parties shall have no rights under the Agreement that would otherwise be prohibited under the Charter. To the extent that any attempted Redemption would be in violation of this Section 6(k), it shall be null and void ab initio, and the Tendering Party shall not acquire any rights or economic interests in REIT Shares otherwise issuable by the Previous General Partner hereunder.

(k)    If, at any time, after a partial redemption of Preferred Units, there are fewer than 68,000 Preferred Units outstanding, the Partnership shall have the right, but not the obligation, to redeem all outstanding Preferred

7

Units by treating each holder of Preferred Units as a Tendering Party who has delivered a Notice of Redemption pursuant to this Section 6 for all of such holder’s Preferred Units, by notice to such holder that the Partnership has elected to exercise its rights under this Section 6(l). Such notice given by the General Partner to a holder of Preferred Units pursuant to this Section 6(l) shall be treated as if it were a Notice of Redemption delivered to the General Partner by such holder. For purposes of this Section 6(l), (i) any holder of Preferred Units (whether or not eligible to be a Tendering Party) may, in the General Partner’s sole and absolute discretion, be treated as a Tendering Party and (ii) the provisions of Sections 6(g)(2) and 6(g)(3) hereof shall not apply, but the remainder of this Section shall apply, mutatis mutandis.

7.    Status of Reacquired Units.

All Preferred Units which shall have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

8.    General.

The ownership of the Preferred Units shall be evidenced by one or more certificates in the form of Annex II hereto. The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the Class Ten Partnership Preferred Units.

9.    Allocations of Income and Loss.

Subject to the terms of Section 5 hereof, for each taxable year, (a) each holder of Preferred Units will be allocated, to the extent possible, net income of the Partnership in an amount equal to the distributions made on such holder’s Preferred Units during such taxable year, and (b) each holder of Preferred Units will be allocated its pro rata share, based on the portion of outstanding Preferred Units held by it, of any net loss of the Partnership that is not allocated to holders of Partnership Common Units or other interests in the Partnership.

10.    Voting Rights.

The holders of the Preferred Units will not have any voting or approval rights, except (a) as required by applicable law or in the Agreement, and (b) as long as any Preferred Units are outstanding, in addition to any other vote or consent of partners required by law or by the Agreement, the affirmative vote or consent of holders of at least 50% of the outstanding Preferred Units will be necessary for effecting any amendment of any of the provisions of this Partnership Unit Designation that materially and adversely affects the rights or preferences of the holders of the Preferred Units. The creation or issuance of any class or series of Partnership units, including, without limitation, any Partnership units that may have rights junior to or, on a parity with, the Preferred Units, will not be deemed to have a material adverse effect on the rights or preferences of the holders of Preferred Units. The issuance of any additional Class Ten Partnership Preferred Units after the date of initial issuance shall be deemed to have a material adverse effect on the rights of holders of Class Ten Partnership Preferred Units, and shall require the affirmative vote or consent of the holders of at least 50% of the outstanding Class Ten Partnership Preferred Units. With respect to the exercise of the above described voting rights, each Preferred Unit will have one (1) vote per Preferred Unit.

11.    Restrictions on Transfer.

Preferred Units are subject to the same restrictions on transfer as are, and the holders of Preferred Units shall be entitled to the same rights of transfer as are, applicable to Common Units as set forth in the Agreement.

The terms of any Vesting Agreement may be modified by the General Partner from time to time in its sole discretion, subject to any restrictions on amendment imposed by the relevant Vesting Agreement or by the Plan or any other Equity Plan, if applicable. LTIP Units that were fully vested when issued, or that have vested and are no longer subject to forfeiture under the terms of a Vesting Agreement, are referred to as “Vested LTIP Units”; all other LTIP Units are referred to as “Unvested LTIP Units.”

(b) Forfeiture. Unless otherwise specified in the relevant LTIP Agreement, upon the occurrence of any event specified in such LTIP Agreement as resulting in either the right of the Partnership to repurchase LTIP

3

Units at a specified purchase price or the forfeiture of any LTIP Units, if the Partnership exercises such right to repurchase or upon the occurrence of the event causing forfeiture in accordance with the applicable LTIP Agreement, then the relevant LTIP Units shall immediately, and without any further action, be treated as cancelled and no longer outstanding for any purpose. Unless otherwise specified in the applicable LTIP Agreement, no consideration or other payment shall be due with respect to any LTIP Units that have been forfeited, other than any distributions payable to holders of such LTIP Units as of a record date prior to the effective date of the forfeiture. Except as otherwise provided in the Agreement (including without limitation Section 4(d) hereof) or any LTIP Agreement, in connection with the repurchase or forfeiture of any holder’s LTIP Units, the balance of such holder’s Capital Account that is attributable to such holder’s LTIP Units shall be reduced by the amount, if any, by which it exceeds the target balance contemplated by Section 4(c) hereof, calculated with respect to such holder’s remaining LTIP Units, if any.

4. Allocations

(a) General. Except as otherwise provided in the Agreement or the relevant LTIP Agreement, Holders of LTIP Units shall be allocated Net Income, Net Loss and depreciation and amortization expenses of the Partnership in amounts per LTIP Unit determined in the same manner as amounts allocated per Partnership Common Unit are determined; provided, however, that for any LTIP Unit that initially has a Sharing Percentage that is less than 100%, until the Catch-Up Year (if any) for such LTIP Unit, the amounts so allocated with respect to such LTIP Unit pursuant to Section 6.2A(3) or Section 6.2B of the Agreement shall be equal to the product of such Sharing Percentage and the amount that would otherwise be allocable with respect to such LTIP Unit pursuant to this Section 4(a). The allocations provided by the preceding sentence shall be subject to Section 6.3B of the Agreement and any special allocations required by Section 4(b) or Section 4(c) hereof. The General Partner is authorized in its discretion to delay or accelerate the participation of the LTIP Units in allocations of Net Income, Net Loss and depreciation and amortization expenses of the Partnership under this Section 4(a), or to adjust the allocations made under this Section 4(a), so that the ratio of (i) the total amount of Net Income, Net Loss and depreciation and amortization expenses of the Partnership allocated with respect to each LTIP Unit in any taxable year, to (ii) the total amount distributed with respect to that LTIP Unit for such taxable year, is more nearly equal to the ratio of (i) the Net Income, Net Loss and depreciation and amortization expenses of the Partnership allocated with respect to the Partnership Common Units for such taxable year, to (ii) the amounts distributed with respect to the Partnership Common Units for such taxable year.

(b) Special Allocations with Respect to LTIP Units in a Catch-Up Year. In the Catch-Up Year (if any) for any LTIP Unit that initially has a Sharing Percentage that is less than 100%, (i) Net Income, Net Loss and depreciation and amortization expenses of the Partnership allocable under Article 6 of the Agreement to holders of Partnership Common Units and LTIP Units not subject to this Section 4(b) shall be recomputed after giving effect to the special allocations with respect to such LTIP Unit under clause (ii) of this Section 4(b), and (ii) the holder of such LTIP Unit shall be specially allocated an amount of Net Income, Net Loss and depreciation and amortization expenses of the Partnership equal to the excess of (x) the respective cumulative amounts that would have been allocated with respect to such LTIP Unit had such LTIP Unit been a Partnership Common Unit during the period from the date of issuance of such LTIP Unit through the end of the Fiscal Year immediately prior to the Catch-Up Year, over (y) the respective cumulative amounts actually allocated with respect to such LTIP Unit during such period. Such special allocation shall be in addition to any amounts allocated to the holder of such LTIP Unit pursuant to Section 4(a).

(c) Special Allocations of Liquidating Gains with Respect to LTIP Units. If Liquidating Gains are allocated under this Section 4(c), Net Income, Net Loss and depreciation and amortization expenses of the Partnership allocable under Article 6 of the Agreement to holders of Partnership Common Units and LTIP Units not subject to this Section 4(c) shall be recomputed without regard to the Liquidating Gains so allocated. After giving effect to the special allocations set forth in Section 6.3.B of the Agreement and Section 4(d) hereof, and notwithstanding the provisions of Section 6.2 of the Agreement, any Liquidating Gains shall first be allocated to the holders of Eligible Units until the Economic Capital Account Balance of each such holder, to the extent

4

attributable to such holder’s ownership of Eligible Units, is equal to (i) the REIT Share Economic Target, multiplied by (ii) the number of such holder’s Eligible Units, it being understood that Liquidating Gains will be so allocated only to the extent each such Eligible Unit is eligible to be allocated Liquidating Gains. Except as otherwise provided in any LTIP Agreement, any such allocations shall be made among the holders of Eligible Units in proportion to the amounts eligible to be allocated to each under this Section 4(c). The parties agree that the intent of this Section 4(c) is to make the Capital Account balances of the holders of LTIP Units, to the extent attributable to their LTIP Units, economically equivalent (on a per-unit basis) to the Market Value of a REIT Share on the date as of which such special allocation pursuant to this Section 4(c) is being made, multiplied by the Conversion Factor, but only to the extent the Partnership has recognized cumulative net gains with respect to its assets since the issuance of the relevant LTIP Unit. The allocations set forth in this Section 4(c) shall be taken into account for determining the Capital Account of each Partner, including for purposes of Section 6.3.C of the Agreement.

(d) Forfeiture Allocations. Upon a forfeiture of any Unvested LTIP Units by any Partner, gross items of income, gain, loss or deduction shall be allocated to such Partner if and to the extent required by final Regulations promulgated after the Effective Date to ensure that allocations made with respect to all unvested Partnership Interests are recognized under Code Section 704(b).

5. Distributions.

(a) Operating Distributions. Except as otherwise provided in the Agreement or the relevant LTIP Agreement, holders of LTIP Units shall be entitled to receive, if, when and as authorized by the General Partner out of funds or other property legally available for the payment of distributions, regular, special, extraordinary or other distributions (other than distributions upon or pursuant to the liquidation of the Partnership) which may be made from time to time, in an amount per LTIP Unit equal to the amount of any such distributions that would have been payable to such holders if the LTIP Units had been Partnership Common Units (if applicable, assuming such LTIP Units were held for the entire period to which such distributions relate); provided, that if any LTIP Unit has a Sharing Percentage then in effect that is less than 100%, the holder of such LTIP Unit will only be entitled to receive such distributions in an amount equal to the product of the Sharing Percentage for such LTIP Unit and the amount that would otherwise be distributable with respect to such LTIP Unit pursuant to this Section 5(a).

(b) Liquidating Distributions. Each holder of LTIP Units shall also be entitled to receive, if, when and as authorized by the General Partner out of funds or other property legally available for the payment of distributions, distributions upon liquidation of the Partnership in an amount equal to the positive balance of such holder’s Capital Account as of the date of liquidation (after taking into account any allocations pursuant to the liquidation) to the extent attributable to the ownership of such LTIP Units as set forth in Section 13.2 of the Agreement.

(c) Distributions Generally. Distributions on the LTIP Units, if authorized, shall be payable on such dates and in such manner as may be authorized by the General Partner. Absent a contrary determination by the General Partner, the payment and record dates for distributions on LTIP Units shall be the same as the payment and record dates for the corresponding distribution on the Partnership Common Units. A holder of LTIP Units will only be entitled to distributions with respect to an LTIP Unit as set forth in this Exhibit BB and, in making distributions pursuant to Section 5.1 of the Agreement, the General Partner of the Partnership shall take into account the provisions of this Section 5.

6. Redemption.

Holders of LTIP Units shall not be entitled to the Redemption right provided for in Section 8.6 of the Agreement, unless, until and to the extent such LTIP Units have been converted into Partnership Common Units.

5

7. Conversion to Partnership Common Units.

(a) A holder of LTIP Units that is a Qualifying Party shall have the right (the “Conversion Right”), at such holder’s option, at any time to convert all or a portion of such holder’s Vested LTIP Units into Partnership Common Units, taking into account all adjustments (if any) made pursuant to Section 8 hereof; provided, however, that a Qualifying Party may not exercise the Conversion Right for less than one thousand (1,000) Vested LTIP Units or, if such Qualifying Party holds less than one thousand (1,000) Vested LTIP Units, all of the Vested LTIP Units held by such Qualifying Party that are not subject to the limitation on conversion under Section 7(b) hereof. Qualifying Parties shall not have the right to convert Unvested LTIP Units into Partnership Common Units until they become Vested LTIP Units; provided, however, that when a Qualifying Party is notified of the expected occurrence of an event that will cause his or her Unvested LTIP Units to become Vested LTIP Units, such Qualifying Party may give the Partnership a Conversion Notice conditioned upon and effective as of the time of vesting and such Conversion Notice, unless subsequently revoked by the Qualifying Party, shall be accepted by the Partnership subject to such condition. In all cases, the conversion of any LTIP Units into Partnership Common Units shall be subject to the conditions and procedures set forth in this Section 7.

(b) A Qualifying Party may convert Vested LTIP Units into an equal number of Partnership Common Units, giving effect to all adjustments (if any) made pursuant to Section 8 hereof; provided, however, that in no event may a Qualifying Party convert a number of Vested LTIP Units that exceeds (x) the Economic Capital Account Balance of such Qualifying Party that is attributable to such Qualifying Party’s ownership of LTIP Units, divided by (y) the REIT Share Economic Target, in each case, determined as of a date on which satisfaction of the Redemption Threshold is being determined (the “Capital Account Limitation”). In order to exercise the Conversion Right, a Qualifying Party shall deliver a Conversion Notice to the Partnership not less than three (3) nor more than ten (10) days prior to the date of conversion (the “Conversion Date”) specified in such Conversion Notice; provided, however, that if the General Partner has not given to the Qualifying Party notice of a proposed or upcoming Transaction at least thirty (30) days prior to the effective date of such Transaction, then the Qualifying Party shall have the right to deliver a Conversion Notice until the earlier of (x) the tenth (10th) day after such notice from the General Partner of a Transaction or (y) the third (3rd) Business Day immediately preceding the effective date of such Transaction. A Conversion Notice shall be provided in the manner provided in Section 15.1 of the Agreement. Each Qualifying Party seeking to convert Vested LTIP Units covenants and agrees with the Partnership that all Vested LTIP Units to be converted pursuant to this Section 7 shall be free and clear of all liens. For purposes of the definition of “Twelve-Month Period” in the Agreement, any holder of LTIP Units that have been converted to Partnership Common Units shall be deemed to have acquired such Partnership Common Units when such LTIP Units were acquired. A holder of LTIP Units that is a Qualifying Party may deliver a Notice of Redemption pursuant to Section 8.6 of the Agreement relating to the Partnership Common Units to be received upon conversion of LTIP Units in advance of the Conversion Date; provided, however, that the Redemption of such Partnership Common Units shall not take place until on or after the Conversion Date. For clarity, it is noted that the objective of this paragraph is to enable a Qualifying Party that satisfies the Twelve-Month Period to effect a Redemption of the Partnership Common Units received upon conversion of Vested LTIP Units simultaneously with such conversion, with the further consequence that, if the Previous General Partner elects to assume the Partnership’s redemption obligation with respect to such Partnership Common Units under Section 8.6 of the Agreement by delivering to such Qualifying Party REIT Shares rather than cash, then such Qualifying Party can receive such REIT Shares simultaneously with the conversion of such Vested LTIP Units into Partnership Common Units. The General Partner shall cooperate with a Qualifying Party to coordinate the timing of the different events described in the foregoing sentence.

(c) The Partnership, at any time at the election of the General Partner, may cause any number of Vested LTIP Units to be converted (a “Forced Conversion”) into an equal number of Partnership Common Units, giving effect to all adjustments (if any) made pursuant to Section 8 hereof; provided, however, that the Partnership may not cause a Forced Conversion of any LTIP Units that would not at the time be eligible for conversion at the option of the holder thereof pursuant to Section 7(b) hereof. In order to exercise its right of Forced Conversion, the Partnership shall deliver a written notice of such Forced Conversion (a “Forced Conversion Notice”) to the applicable holder of LTIP Units specifying the number of LTIP Units subject to the Forced Conversion, which

6

notice shall be given not less than ten (10) nor more than sixty (60) days prior to the Conversion Date specified in such notice. A Forced Conversion Notice shall be provided in the manner provided in Section 15.1 of the Agreement.

(d) A conversion of Vested LTIP Units for which the holder thereof has given a Conversion Notice, or the Partnership has given a Forced Conversion Notice, shall occur automatically after the close of business on the applicable Conversion Date without any action on the part of such holder of LTIP Units, as of which time such holder of LTIP Units shall be credited on the books and records of the Partnership as of the opening of business on the next day with the number of Partnership Common Units into which such LTIP Units were converted. After the conversion of LTIP Units as aforesaid, the Partnership shall deliver to such holder of LTIP Units, upon his or her written request, a certificate of the General Partner certifying the number of Partnership Common Units and remaining LTIP Units, if any, held by such person immediately after such conversion. The Assignee of any Limited Partner may exercise the rights of such Limited Partner pursuant to this Section 7 and such Limited Partner shall be bound by the exercise of such rights by the Assignee.

(e) For purposes of making future allocations under Section 4(c) hereof and applying the Capital Account Limitation, if any LTIP Units are converted into Partnership Common Units, the portion of the Economic Capital Account Balance of the holder of such LTIP Units that is treated as attributable to such holder’s LTIP Units shall be reduced, as of the date of conversion, by the product of the number of LTIP Units converted and the REIT Share Economic Target, determined as of the relevant Conversion Date.

(f) If the Partnership or the Previous General Partner shall be a party to any transaction (including without limitation a merger, consolidation, statutory exchange, sale of all or substantially all of the Partnership’s assets or other business combination or reorganization, but excluding any Adjustment Event, in each case, as a result of which Partnership Common Units shall be exchanged for or converted into the right, or the holders shall otherwise be entitled, to receive cash, securities or other property or any combination thereof (each of the foregoing being referred to herein as a “Transaction”)), then the General Partner shall, immediately prior to the Transaction, exercise its right to cause a Forced Conversion with respect to the maximum number of LTIP Units then eligible for conversion, taking into account any allocations that occur in connection with the Transaction or that would occur in connection with the Transaction if the assets of the Partnership were sold at the Transaction price or the portion thereof attributable to the Partnership, as determined by the General Partner in good faith, or if applicable, at a value for the Partnership assets determined by the General Partner in good faith using the value attributed to the Partnership Common Units in the context of the Transaction (in which case the Conversion Date shall be the effective date of the Transaction and the conversion shall occur immediately prior to the effectiveness of the Transaction). In anticipation of such Forced Conversion and the consummation of the Transaction, the Partnership shall use commercially reasonable efforts to cause each holder of LTIP Units to be afforded the right to receive in connection with such Transaction in consideration for the Partnership Common Units into which his or her LTIP Units will be converted the same kind and amount of cash, securities and other property (or any combination thereof) receivable upon the consummation of such Transaction by a holder of the same number of Partnership Common Units, assuming such holder is not a Person with which the Partnership consolidated or into which the Partnership merged or which merged into the Partnership or to which such sale or transfer was made, as the case may be (a “Constituent Person”), or an affiliate of a Constituent Person. In the event that holders of Partnership Common Units have the opportunity to elect the form or type of consideration to be received upon consummation of the Transaction, prior to such Transaction, the General Partner shall give prompt written notice to each holder of LTIP Units of such opportunity, and shall use commercially reasonable efforts to afford each holder of LTIP Units the right to elect, by written notice to the General Partner, the form or type of consideration to be received upon conversion of each LTIP Unit held by such holder into Partnership Common Units in connection with such Transaction. If a holder of LTIP Units fails to make such an election, such holder (and any of its transferees) shall receive upon conversion of each LTIP Unit held by him or her (or by any of his or her transferees) the same kind and amount of consideration that a holder of Partnership Common Units would receive if such holder of Partnership Common Units failed to make such an election. Subject to the rights of the Partnership and the General Partner under any LTIP Agreement, the Partnership shall use

7

commercially reasonable efforts to cause the terms of any Transaction to be consistent with the provisions of this Section 7(f) and to enter into an agreement with the successor or acquiring entity, as the case may be, for the benefit of any holder of LTIP Units that will not be converted into Partnership Common Units in connection with the Transaction that will (i) contain provisions enabling the Qualifying Parties that remain outstanding after such Transaction to convert their LTIP Units into securities as comparable as reasonably possible under the circumstances to the Partnership Common Units and (ii) preserve as far as reasonably possible under the circumstances the distribution, special allocation, conversion, and other rights set forth in the Agreement, including this Exhibit BB, for the benefit of the holder of LTIP Units.

(g) No conversion of LTIP Units into Partnership Common Units may be made by a Person if, based on the advice of the Partnership’s counsel or accounting firm, the Partnership believes there is a material risk that such conversion could (i) result in the Partnership’s being treated as an association taxable as a corporation, (ii) adversely affect the ability of the Previous General Partner to continue to qualify as a REIT or subject the Previous General Partner to any additional taxes under Section 857 or Section 4981 of the Code, or (iii) be effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code or cause the Partnership to fail to qualify for a safe harbor from such treatment which the Partnership desires to preserve.

8. Adjustments.

The Partnership shall maintain at all times a one-to-one correspondence between LTIP Units and Partnership Common Units for conversion, distributions, allocations and other purposes, including without limitation complying with the following procedures; provided, that the foregoing is not intended to alter (a) differences as a result of a Sharing Percentage that is less than 100%, (b) the special allocations pursuant to Section 4 hereof, or (c) differences between distributions to be made with respect to LTIP Units and Partnership Common Units pursuant to Section 13.2 of the Agreement and Section 5(b) hereof in the event that the Capital Accounts attributable to the LTIP Units are less than those attributable to Partnership Common Units due to insufficient special allocations pursuant to Section 4(c) hereof or related provisions. If an Adjustment Event (as defined below) occurs, then the General Partner shall take any action reasonably necessary, including any amendment to the Agreement or update Exhibit A to the Agreement adjusting the number of outstanding LTIP Units or subdividing or combining outstanding LTIP Units, to maintain a one-for-one conversion and economic equivalence ratio between Partnership Common Units and LTIP Units. The following shall be “Adjustment Events”: (i) the Partnership makes a distribution on all outstanding Partnership Common Units in Partnership Units, (ii) the Partnership subdivides the outstanding Partnership Common Units into a greater number of units or combines the outstanding Partnership Common Units into a smaller number of units, or (iii) the Partnership issues any Partnership Units in exchange for its outstanding Partnership Common Units by way of a reclassification or recapitalization of its Partnership Common Units. If more than one Adjustment Event occurs, any adjustment to the LTIP Units need be made only once using a single formula that takes into account each and every Adjustment Event as if all Adjustment Events occurred simultaneously. For the avoidance of doubt, the following shall not be Adjustment Events: (x) the issuance of Partnership Units in a financing, reorganization, acquisition or other similar business transaction, (y) the issuance of Partnership Units pursuant to any employee benefit or compensation plan or distribution reinvestment plan, or (z) the issuance of any Partnership Units to the General Partner in respect of a capital contribution to the Partnership. If the Partnership takes an action affecting the Partnership Common Units other than actions specifically described above as “Adjustment Events,” and in the opinion of the General Partner such action would require an action to maintain the one-to-one correspondence described above, the General Partner shall have the right to take such action, to the extent permitted by law, the Plan and by any other applicable Equity Plan or other compensatory arrangement or incentive program pursuant to which LTIP Units are issued, in such manner and at such time as the General Partner, in its sole discretion, may determine to be reasonably appropriate under the circumstances. If an amendment is made to the Agreement adjusting the number of outstanding LTIP Units as herein provided, the Partnership shall promptly file in the books and records of the Partnership an officer’s certificate setting forth a brief statement of the facts requiring such adjustment, which certificate shall be conclusive evidence of the correctness of such adjustment absent

8

manifest error. Promptly after the filing of such certificate, the Partnership shall mail a notice to each holder of LTIP Units setting forth the adjustment to his or her LTIP Units and the effective date of such adjustment. Any adjustment to the number of outstanding LTIP Units pursuant to this Section 8 shall be binding on the Partnership and every Limited Partner.

9. Status of Reacquired Units.

All LTIP Units that have been issued and reacquired in any manner by the Partnership shall be deemed cancelled and no longer outstanding.

10. General.

The General Partner shall amend Exhibit A to the Agreement from time to time to the extent necessary to reflect accurately the issuance of, and subsequent redemption, or any other event having an effect on the ownership of, the LTIP Units. Unless the General Partner determines otherwise, LTIP Units shall not be certificated.

11. Voting Rights.

Limited Partners holding LTIP Units shall have the same voting rights as Limited Partners holding Partnership Common Units, with the LTIP Units voting together as a single class with the Partnership Common Units and having one vote per LTIP Unit, and holders of LTIP Units shall not be entitled to approve, vote on or consent to any other matter.

12. Restrictions on Transfer.

Subject to the terms of any Vesting Agreement, LTIP Units are subject to the same restrictions on transfer, and the holders of LTIP Units shall be entitled to the same rights of transfer, as are applicable to Partnership Common Units as set forth in the Agreement.

13. Section 83 Safe Harbor.

Each Partner authorizes the General Partner to elect to apply the safe harbor (the “Section 83 Safe Harbor”) set forth in proposed Regulations Section 1.83-3(l) and proposed Internal Revenue Service Revenue Procedure published in Notice 2005-43 (together, the “Proposed Section 83 Safe Harbor Regulation”) (under which the fair market value of a Partnership Interest that is Transferred in connection with the performance of services is treated as being equal to the liquidation value of the interest), or in similar Regulations or guidance, if such Proposed Section 83 Safe Harbor Regulation or similar Regulations are promulgated as final or temporary Regulations. If the General Partner determines that the Partnership should make such election, the General Partner is hereby authorized to amend the Agreement without the consent of any other Partner to provide that (i) the Partnership is authorized and directed to elect the Section 83 Safe Harbor, (ii) the Partnership and each of its Partners (including any Person to whom a Partnership Interest, including an LTIP Unit, is Transferred in connection with the performance of services) will comply with all requirements of the Section 83 Safe Harbor with respect to all Partnership Interests Transferred in connection with the performance of services while such election remains in effect, and (iii) the Partnership and each of its Partners will take all actions necessary, including providing the Partnership with any required information, to permit the Partnership to comply with the requirements set forth or referred to in the applicable Regulations for such election to be effective until such time (if any) as the General Partner determines, in its sole discretion, that the Partnership should terminate such election. The General Partner is further authorized to amend the Agreement to modify Article 6 of the Agreement to the extent the General Partner determines in its discretion that such modification is necessary or desirable as a result of the issuance of any applicable law, Regulations, notice or ruling relating to the tax treatment of the transfer of Partnership Interests in connection with the performance of services. Notwithstanding anything to the contrary in the Agreement, each Partner expressly confirms that it will be legally bound by any such amendment.
