SUMMARY

A. Introduction.

General

The enclosed Election Form (the “Election Form”) and the attachments and exhibits hereto (together with the Election Form, the “Election Package”) are being provided by Shelter Realty IV Corporation (“Shelter Realty” or the “Corporate General Partner”), the corporate general partner of Shelter Properties IV Limited Partnership, a South Carolina limited partnership (“Shelter” or the “Partnership”), and AIMCO Properties, L.P., a Delaware limited partnership (“Aimco OP”), to each of the eligible holders of units of limited partnership interest (the “Limited Partners”) in the Partnership, in connection with the Agreement and Plan of Merger, dated as of February 11, 2011 (as amended or supplemented from time to time, the “Merger Agreement”), by and among the Partnership, Aimco OP and AIMCO Shelter Merger Sub LLC, a South Carolina limited liability company (the “Merger Subsidiary”). Pursuant to the Merger Agreement, on February 11, 2011, the Merger Subsidiary was merged with and into the Partnership, with the Partnership continuing as the surviving entity (the “Merger”).

Election of Cash or OP Units

Pursuant to the Merger Agreement, upon consummation of the Merger, each unit of limited partnership interest of Shelter (each a “Limited Partnership Unit”) outstanding immediately prior to consummation of the Merger and held by Limited Partners (other than Limited Partnership Units as to which appraisal rights are elected), was converted into the right to receive, at the election of the holder of such Limited Partnership Unit, either $4.50 in cash (the “Cash Consideration”) or 0.18 partnership common units (“OP Units”) of Aimco OP (the “OP Unit Consideration” and, together with the Cash Consideration, the “Merger Consideration”); provided, however, that if a Limited Partner is a resident of the State of California, then such Limited Partner is only entitled to the Cash Consideration for each Limited Partnership Unit. As a result of the Merger, the separate existence of the Merger Subsidiary terminated, and the Partnership, as the surviving entity in the Merger, became directly and indirectly owned by Aimco OP.

Additional Cash Payment

In addition to and separate from the Merger Consideration, each Limited Partner unaffiliated with Aimco OP or its affiliates (including Limited Partners electing to receive the OP Unit Consideration) may elect to receive an additional cash payment of $3.75 per Limited Partnership Unit in exchange for executing a waiver and release of certain potential claims such unaffiliated Limited Partner may have had in the past or may now have (through and including the date of the consummation of the Merger) against Aimco OP, its present and former parents, subsidiaries and affiliates, and certain other persons and entities, including but not limited to claims related to the Merger Agreement and the transactions contemplated thereby and claims related to the ownership of Limited Partnership Units. In order to receive such additional payment, Limited Partners must complete Section 3 of the enclosed Election Form, execute the waiver and release that is attached to the enclosed Election Form as Attachment 6 and return both the Election Form and the executed waiver and release to AIMCO Properties, L.P., c/o Eagle Rock Proxy Advisors, LLC as described below.

Election Form and Election Deadline

Limited Partners may elect their form of consideration by completing and returning the enclosed Election Form and all necessary attachments in accordance with the instructions. Limited Partners may choose to accept the Cash Consideration or the OP Unit Consideration. Limited Partners who do not wish to accept either the Cash Consideration or the OP Unit Consideration may choose to seek an appraisal by arbitration of the fair value of their Limited Partnership Units, in each case, by making the appropriate election on the Election Form.

The attached Election Form and all necessary attachments must be received by AIMCO Properties, L.P., c/o Eagle Rock Proxy Advisors, LLC, by 5:00 p.m., New York time, on March 14, 2011 (the "Election Deadline”) by mail at 12 Commerce Drive, Cranford, New Jersey 07016, or by fax at (908) 497-2349. If

Appraisal Rights of Limited Partners

Limited Partners are not entitled to dissenters’ appraisal rights under applicable law or the Partnership’s partnership agreement in connection with the Merger. However, Limited Partners who do not wish to accept the Cash Consideration or the OP Unit Consideration pursuant to the Merger have the right to seek an appraisal by arbitration of the fair value of their Limited Partnership Units pursuant to the Merger Agreement. Prosecution of these contractual appraisal rights will involve an arbitration proceeding, and the consideration paid to a Limited Partner after the prosecution of such contractual appraisal rights will be a cash payment, resulting in a taxable event to such Limited Partner.

If you would like to seek an arbitrated appraisal of the fair value of your Limited Partnership Units, you must properly complete, execute and return the Election Form in the manner described in Section H of the attached Instructions by the Election Deadline.

BY MAILING THIS ELECTION PACKAGE TO THE LIMITED PARTNERS, AIMCO OP IS HEREBY NOTIFYING LIMITED PARTNERS OF THE CONSUMMATION OF THE MERGER AND THAT APPRAISAL RIGHTS ARE AVAILABLE FOR ANY OR ALL LIMITED PARTNERSHIP UNITS HELD BY LIMITED PARTNERS.

Spousal Consent. If you are married, your spouse must sign the Spousal Consent included as Attachment 1 to the Election Form, releasing any potential rights he or she may have in the Limited Partnership Units.

Method of Payment of Cash Consideration. Eagle Rock Proxy Advisors, LLC will act as paying agent in connection with the Merger (“Paying Agent”) and will deliver to holders of Limited Partnership Units any Cash Consideration to which they are entitled pursuant to the Merger Agreement and as specified in the Election Form.

Material United States Federal Income Tax Consequences. In general, under applicable United States federal income tax laws and regulations: (1) any payment of cash for Limited Partnership Units will be treated as a sale of such Limited Partnership Units by such holder, and (2) any exchange of Limited Partnership Units for OP Units under the terms of the Merger Agreement will be treated, in accordance with Sections 721 and 731 of the Code, as a tax free transaction, except to the extent described in the sections of the Information Statement/Prospectus captioned “Material United States Federal Income Tax Matters — United States Federal Income Tax Consequences Relating to the Merger.” Please refer to the sections of the Information Statement/Prospectus captioned “Material United States Federal Income Tax Consequences of the Merger” and “Material United States Federal Income Tax Matters.” WE URGE YOU TO CONSULT YOUR OWN TAX ADVISOR FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER AND THE ELECTION.

The United Stated Federal income tax treatment of the additional cash payment received in exchange for executing a waiver and release of certain claims is uncertain. Aimco OP intends to treat the additional cash payment as a payment made for the waiver and release of certain claims, and not as additional Merger Consideration, and

intends to report the additional cash payment accordingly. No assurance can be given that the IRS would not assert that the additional cash payment should be treated as part of the Merger Consideration. HOLDERS WHO ELECT TO RECEIVE THE ADDITIONAL CASH PAYMENT IN EXCHANGE FOR EXECUTING A WAIVER AND RELEASE SHOULD CONSULT THEIR TAX ADVISORS CONCERNING THE TAX TREATMENT OF SUCH PAYMENT.

Questions and Requests for Information or Assistance. If you have any questions or need assistance to complete the Election Form or any of the attachments, please contact the information agent, Eagle Rock Proxy Advisors, LLC, by mail at 12 Commerce Drive, Cranford, New Jersey 07016; by fax at (908) 497-2349; or by telephone at (800) 217-9608. You may also obtain additional copies of the Election Package or any of the attachments thereto from the information agent at the above address.

E. Description of Attachments.

Attachment 1 — Spousal Consent. If you are married, your spouse must sign the Spousal Consent provided as Attachment 1 to the Election Form, consenting to your election and releasing any potential rights he or she may have in the Limited Partnership Units.

Attachment 2 — Substitute Form W-9. Under U.S. federal income tax law, Aimco OP is required to file a report with the IRS disclosing any payments being made to each holder of Limited Partnership Units. In order to avoid withholding tax and to ensure proper backup withholding of U.S. federal income tax on any payments received in exchange for the Limited Partnership Units, unless an exemption applies, you must provide Aimco OP with your correct taxpayer identification number (“TIN”) on the Substitute Form W-9, which is attached to the Election Form as Attachment 2, and certify, under penalty of perjury, that such number is correct and that you are not otherwise subject to backup withholding. If the correct TIN and certifications are not provided, a $50 penalty may be imposed by the IRS, and payments made for the exchange of Limited Partnership Units may be subject to backup withholding, currently at a rate of 28% (through 2012). In addition, if you make a false statement that results in no imposition of backup withholding, and there was no reasonable basis for making such a statement, a $500 penalty may also be imposed by the IRS.

Backup withholding is not an additional federal income tax. It is a required, estimated income tax payment that may either be greater or less than the actual income tax due from a taxpayer, once the tax is actually determined at a later date. If backup withholding is imposed, you may either owe more money or be entitled to a refund when filing your tax return for 2011.

The TIN that must be provided on the Substitute Form W-9 (Attachment 2 to the Election Form) is that of the holder(s) of the Limited Partnership Units at the effective time of the Merger. The TIN for an individual is his or her social security number. If the holder of Limited Partnership Units has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future, he or she may write “Applied For” in Part I. Notwithstanding that the person has written “Applied For” in Part I, the Paying Agent will withhold 28% of all payments with respect to the conversion of Limited Partnership Units made prior to the time it is provided with a properly certified TIN.

Exempt persons (including, among others, corporations) are not subject to backup withholding. A foreign individual may qualify as an exempt person by submitting Form W-8ECI or a substitute Form W-8ECI, signed under penalty of perjury, certifying to such person’s exempt status. A form of such statement can be obtained from Aimco OP. A unitholder should consult his or her tax advisor as to such holder’s qualification for an exemption from backup withholding and the procedure for obtaining such exemption.

If you elect to receive the OP Unit Consideration, you will not become a limited partner in Aimco OP unless and until you have provided either a Substitute Form W-9 or a Form W-8ECI (or substitute Form W-8ECI), as applicable, or made satisfactory arrangements for the payment and satisfaction of any backup withholding tax obligation that would be imposed in connection with such exchange.

The signature and date provided on the Substitute Form W-9 will serve to verify that the TIN and withholding information provided in the Election Form are true, correct and complete.

vii

See the attached “Guidelines for Request for Taxpayer Identification Number on Substitute Form W-9” for additional instructions.

Attachments 3A and 3B — FIRPTA Certificates. If you are a U.S. person, you must complete and sign the FIRPTA withholding certificate. The failure by a U.S. person to timely deliver a FIRPTA withholding certificate may require a certain amount of Merger Consideration to be withheld. The FIRPTA certificates for individuals and entities are attached to the Election Form as Attachments 3A and 3B, respectively. Non-U.S. persons and persons who do not complete the FIRPTA certificate will be subject to FIRPTA withholding of 10% of the amount realized on the exchange of Limited Partnership Units.

Attachment 4 — Signature Page to Aimco OP Partnership Agreement. If you elect to receive the OP Unit Consideration, then by signing and delivering the Election Form, you consent to the terms of the Amended and Restated Agreement of Limited Partnership of AIMCO Properties, L.P., as amended (the “Aimco OP Partnership Agreement”), and acknowledge that the rights, preferences and privileges of the OP Units to be received in the Merger will be governed by the Aimco OP Partnership Agreement. If you are electing to receive the OP Unit Consideration, you must execute and return the signature page for the Aimco OP Partnership Agreement with your Election Form. Please refer to the sections of the Information Statement/Prospectus captioned “Description of Aimco OP Units; Summary of Aimco OP Partnership Agreement,” “Risk Factors—Risks Related to an Investment in OP Units” and “Comparison of Shelter Limited Partnership Units and Aimco OP Units” for more information. The Aimco OP Partnership Agreement has been filed with the Securities and Exchange Commission (“SEC”). You may read and copy the document at the SEC’s public reference rooms in Washington, D.C.; New York, New York and Chicago, Illinois.

In addition, you may obtain a full copy of the Aimco OP Partnership Agreement, without charge, by contacting the information agent at the address listed in Section D of these Instructions, in the subsection captioned “General — Questions and Requests for Information or Assistance.”

Attachment 5 — Revocation of Election Form. You may revoke any previously delivered election at any time prior to the Election Deadline by submitting a properly completed and executed Revocation of Election Form to AIMCO Properties, L.P., c/o Eagle Rock Proxy Advisors, LLC. Any previously delivered election that is properly revoked will be deemed not to have been validly made, and you must properly complete and execute a new Election Form and return it prior to the Election Deadline to make a new valid election. If you properly revoke an effective election and then do not make a new valid election by the Election Deadline, you will be deemed to have made an election to receive the Cash Consideration in the Merger, and all of your Limited Partnership Units will automatically be converted into the Cash Consideration.

Attachment 6 — Waiver and Release Form. You may elect to receive an additional cash payment of $3.75 per Limited Partnership Unit by executing and submitting the waiver and release form attached to this Election Form as Attachment 6. By executing the waiver and release form, you are waiving and releasing certain potential claims you may have had in the past or may now have (through and including the date of the consummation of the Merger) against Aimco OP, its present and former parents, subsidiaries and affiliates, and certain other persons and entities, including but not limited to claims related to the Merger Agreement and the transactions contemplated thereby and claims related to the ownership of Limited Partnership Units.

THE IRS DOES NOT REQUIRE YOUR CONSENT TO ANY PROVISION OF THIS DOCUMENT OTHER THAN THE CERTIFICATIONS REQUIRED TO AVOID BACKUP WITHHOLDING.

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

General Instructions

Section references are to the Internal Revenue Code unless otherwise noted.

Purpose of Form

A person who is required to file an information return with the IRS must obtain your correct taxpayer identification number (TIN) to report, for example, income paid to you, real estate transactions, mortgage interest you paid, acquisition or abandonment of secured property, cancellation of debt, or contributions you made to an IRA.

Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and, when applicable, to:

1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued),

2. Certify that you are not subject to backup withholding, or

3. Claim exemption from backup withholding if you are a U.S. exempt payee. If applicable, you are also certifying that as a U.S. person, your allocable share of any partnership income from a U.S. trade or business is not subject to the withholding tax on foreign partners’ share of effectively connected income.

Note. If a requester gives you a form other than Form W-9 to request your TIN, you must use the requester’s form if it is substantially similar to this Form W-9.

Definition of a U.S. person. For federal tax purposes, you are considered a U.S. person if you are:

•		An individual who is a U.S. citizen or U.S. resident alien,

•		A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States,

•		An estate (other than a foreign estate), or

•		A domestic trust (as defined in Regulations section 301.7701-7).

Special rules for partnerships. Partnerships that conduct a trade or business in the United States are generally required to pay a withholding tax on any foreign partners’ share of income from such business. Further, in certain cases where a Form W-9 has not been received, a partnership is required to presume that a partner is a foreign person, and pay the withholding tax. Therefore, if you are a U.S. person that is a partner in a partnership conducting a trade or business in the United States, provide Form W-9 to the partnership to establish your U.S. status and avoid withholding on your share of partnership income.

The person who gives Form W-9 to the partnership for purposes of establishing its U.S. status and avoiding withholding on its allocable share of net income from the partnership conducting a trade or business in the United States is in the following cases:

•		The U.S. owner of a disregarded entity and not the entity,

•		The U.S. grantor or other owner of a grantor trust and not the trust, and

•		The U.S. trust (other than a grantor trust) and not the beneficiaries of the trust.

Foreign person. If you are a foreign person, do not use Form W-9. Instead, use the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities).

Nonresident alien who becomes a resident alien. Generally, only a nonresident alien individual may use the terms of a tax treaty to reduce or eliminate U.S. tax on certain types of income. However, most tax treaties contain a provision known as a “saving clause.” Exceptions specified in the saving clause may permit an exemption from tax to continue for certain types of income even after the payee has otherwise become a U.S. resident alien for tax purposes.

If you are a U.S. resident alien who is relying on an exception contained in the saving clause of a tax treaty to claim an exemption from U.S. tax on certain types of income, you must attach a statement to Form W-9 that specifies the following five items:

1. The treaty country. Generally, this must be the same treaty under which you claimed exemption from tax as a nonresident alien.

2. The treaty article addressing the income.

3. The article number (or location) in the tax treaty that contains the saving clause and its exceptions.

4. The type and amount of income that qualifies for the exemption from tax.

5. Sufficient facts to justify the exemption from tax under the terms of the treaty article.

Example. Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under U.S. law, this student will become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April 30, 1984) allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States. A Chinese student who qualifies for this exception (under paragraph 2 of the first protocol) and is relying on this exception to claim an exemption from tax on his or her scholarship or fellowship income would attach to Form W-9 a statement that includes the information described above to support that exemption.

If you are a nonresident alien or a foreign entity not subject to backup withholding, give the requester the appropriate completed Form W-8.

What is backup withholding? Persons making certain payments to you must under certain conditions withhold and pay to the IRS 28% of such payments. This is called “backup withholding.” Payments that may be subject to backup withholding include interest, tax-exempt interest, dividends, broker and barter exchange transactions, rents, royalties, nonemployee pay, and certain payments from fishing boat operators. Real estate transactions are not subject to backup withholding.

You will not be subject to backup withholding on payments you receive if you give the requester your correct TIN, make the proper certifications, and report all your taxable interest and dividends on your tax return.

Payments you receive will be subject to backup withholding if:

1. You do not furnish your TIN to the requester,

2. You do not certify your TIN when required (see the Part II instructions on page 3 for details),

3. The IRS tells the requester that you furnished an incorrect TIN,

4. The IRS tells you that you are subject to backup withholding because you did not report all your interest and dividends on your tax return (for reportable interest and dividends only), or

5. You do not certify to the requester that you are not subject to backup withholding under 4 above (for reportable interest and dividend accounts opened after 1983 only).

Certain payees and payments are exempt from backup withholding. See the instructions below and the separate Instructions for the Requester of Form W-9.

Also see Special rules for partnerships on page 1.

Penalties

Failure to furnish TIN. If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

Civil penalty for false information with respect to withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

Criminal penalty for falsifying information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

Specific Instructions

Barter exchange transactions and patronage dividends			Exempt payees 1 through 5

Part I. Taxpayer Identification Number (TIN)

Enter your TIN in the appropriate box. If you are a resident alien and you do not have and are not eligible to get an SSN, your TIN is your IRS individual taxpayer identification number (ITIN). Enter it in the social security number box. If you do not have an ITIN, see How to get a TIN below.

If you are a sole proprietor and you have an FIN, you may enter either your SSN or EIN. However, the IRS prefers that you use your SSN.

If you are a single-member LLC that is disregarded as an entity separate from its owner (see Limited liability company (LLC) on page 2), enter the owner’s SSN (or EIN, if the owner has one). Do not enter the disregarded entity’s EIN. If the LLC is classified as a corporation or partnership, enter the entity’s EIN.

Note. See the chart on page 4 for further clarification of name and TIN combinations.

How to get a TIN. If you do not have a TIN, apply for one immediately. To apply for an SSN, get Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at www.ssa.gov. You may also get this form by calling 1-800-772-1213. Use Form W-7, Application for IRS Individual Taxpayer Identification Number, to apply for an ITIN, or Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can apply for an EIN online by accessing the IRS website at www.irs.gov/businesses and clicking on Employer

Identification Number (EIN) under Starting a Business. You can get Forms W-7 and SS-4 from the IRS by visiting www.irs.gov or by calling 1-800-TAX-FORM (1-800-829-3676).

If you are asked to complete Form W-9 but do not have a TIN, write “Applied For” in the space for the TIN, sign and date the form, and give it to the requester. For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.

Note. Entering “Applied For” means that you have already applied for a TIN or that you intend to apply for one soon.

Caution: A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.

Part II. Certification

To establish to the withholding agent that you are a U.S. person, or resident alien, sign Form W-9. You may be requested to sign by the withholding agent even if items 1, 4, and 5 below indicate otherwise.

For a joint account, only the person whose TIN is shown in Part I should sign (when required). Exempt payees, see Exempt Payee on page 2.

Signature requirements. Complete the certification as indicated in 1 through 5 below.

1. Interest, dividend, and barter exchange accounts opened before 1984 and broker accounts considered active during 1983. You must give your correct TIN, but you do not have to sign the certification.

2. Interest, dividend, broker, and barter exchange accounts opened after 1983 and broker accounts considered inactive during 1983. You must sign the certification or backup withholding will apply. If you are subject to backup withholding and you are merely providing your correct TIN to the requester, you must cross out item 2 in the certification before signing the form.

3. Real estate transactions. You must sign the certification. You may cross out item 2 of the certification.

4. Other payments. You must give your correct TIN, but you do not have to sign the certification unless you have been notified that you have previously given an incorrect TIN. “Other payments” include payments made in the course of the requester’s trade or business for rents, royalties, goods (other than bills for merchandise), medical and health care services (including payments to corporations), payments to a nonemployee for services, payments to certain fishing boat crew members and fishermen, and gross proceeds paid to attorneys (including payments to corporations).

5. Mortgage interest paid by you, acquisition or abandonment of secured property, cancellation of debt, qualified tuition program payments (under section 529), IRA, Coverdell ESA, Archer MSA or HSA contributions or distributions, and pension distributions.

Secure Your Tax Records from Identity Theft

Identity theft occurs when someone uses your personal information such as your name, social security number (SSN), or other identifying information, without your permission, to commit fraud or other crimes. An identity thief may use your SSN to get a job or may file a tax return using your SSN to receive a refund.

To reduce your risk:

•

Protect your SSN,

•

Ensure your employer is protecting your SSN, and

•

Be careful when choosing a tax preparer.

Call the IRS at 1-800-829-1040 if you think your identity has been used inappropriately for tax purposes.

Victims of identity theft who are experiencing economic harm or a system problem, or are seeking help in resolving tax problems that have not been resolved through normal channels, may be eligible for Taxpayer Advocate Service (TAS) assistance. You can reach TAS by calling the TAS toll-free case intake line at 1-877-777-4778 or TTY/TDD 1-800-829-4059.

FIRPTA CERTIFICATE FOR ENTITIES — NON-FOREIGN PERSON AFFIDAVIT

Entity Transferor

Section 1445 of the Internal Revenue Code provides that a transferee of a U.S. real property interest must withhold tax if the transferor is a foreign person. For U.S. tax purposes (including Section 1445), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property and not the disregarded entity. To inform the transferee that withholding of tax is not required upon the disposition of a U.S. real property interest by ____________________________________ (“Transferor”), the undersigned hereby certifies the following on behalf of Transferor:

1.	Transferor is not a foreign corporation, foreign partnership, foreign trust, or foreign estate (as those terms are defined in the Internal Revenue Code and Treasury Regulations);

2.	Transferor is not a disregarded entity as defined in Treasury Regulations Section 1.1445-2(b)(2)(iii);

3.	Transferor’s U.S. taxpayer identification number is __________________; and

4.	Transferor’s office address is:

		.

Transferor understands that this certification may be disclosed to the Internal Revenue Service by the transferee and that any false statement contained herein could be punished by fine, imprisonment, or both.

Under penalties of perjury I declare that I have examined this certification and to the best of my knowledge and belief it is true, correct and complete, and I further declare that I have the authority to sign this document on behalf of Transferor.

APPRAISAL RIGHTS OF LIMITED PARTNERS

Capitalized terms used but not defined herein shall have the respective meanings ascribed thereto in the Agreement and Plan of Merger, dated as of February 11, 2011 (the “Merger Agreement”), by and among Shelter Properties IV Limited Partnership , a South Carolina limited partnership (“Shelter”), AIMCO Shelter Merger Sub LLC, a South Carolina limited liability company (the “Aimco Subsidiary”), and AIMCO Properties, L.P., a Delaware limited partnership (“Aimco OP”). In connection with the Merger, limited partners of Shelter shall have the following appraisal rights:

(a) Any limited partner who holds Limited Partnership Units on the effective date of the Merger who has not consented to the Merger (the “Nonconsenting Limited Partners”) and who has otherwise complied with paragraph (b) hereof shall be entitled to an appraisal by arbitration of the fair value of the Nonconsenting Limited Partner’s Limited Partnership Units. This arbitration shall be conducted in Denver, Colorado, in accordance with the Commercial Arbitration Rules of the American Arbitration Association by a panel of three arbitrators selected by Aimco OP. Any arbitration award shall be appealable in the Federal District Court located in Denver, Colorado.

(b) Within 10 days after the effective date of the Merger, Aimco OP shall notify each of the Nonconsenting Limited Partners of the consummation of the Merger, the effective date of the Merger and that appraisal rights are available for any or all Limited Partnership Units held by Nonconsenting Limited Partners, and shall include in such notice a copy of this Annex. Such notice shall include an Election Form pursuant to which Nonconsenting Limited Partners may elect an appraisal by arbitration of the fair value of their Limited Partnership Units pursuant to paragraph (a) hereof. Any limited partner who holds Limited Partnership Units on the effective date of the Merger and who has not consented to the Merger shall be entitled to receive such notice and may, within 30 days after the date of mailing of such notice (such 30th day being the “Election Deadline”), demand from Aimco OP the appraisal of his or her Limited Partnership Units by making the appropriate election in the Election Form in accordance with the instructions thereto. Each completed Election Form must be delivered to the address, and within the time period, specified in the instructions to the Election Form. If a Nonconsenting Limited Partner fails to properly complete an Election Form or return it to the correct address within the specified time period, such Nonconsenting Limited Partner shall be deemed to have elected not to seek an appraisal of his or her Limited Partnership Units, and will be deemed to have elected the Cash Consideration.

(c) At any time prior to the Election Deadline, any Nonconsenting Limited Partner who has made a demand for appraisal of his or her Limited Partnership Units shall have the right to withdraw his or her demand for appraisal and to accept the Cash Consideration payable pursuant to the Merger Agreement. Nonconsenting Limited Partners who wish to withdraw their demands must do so in writing delivered to AIMCO Properties, L.P., c/o Eagle Rock Proxy Advisors, LLC, by mail at 12 Commerce Drive, Cranford, New Jersey, 07016, or by fax at (908) 497-2349. At any time prior to 20 days after the Election Deadline, any Nonconsenting Limited Partner who has complied with the requirements of subsections (a) and (b) hereof, upon written request, shall be entitled to receive from Aimco OP a statement setting forth the aggregate number of Limited Partnership Units with respect to which Nonconsenting Limited Partners have made demands for appraisal and the aggregate number of holders of such Limited Partnership Units. Such written statement shall be mailed to the Nonconsenting Limited Partner within 10 days after such Nonconsenting Limited Partner’s written request for such a statement is received by Aimco OP or within 20 days after the Election Deadline, whichever is later.

(d) Upon the submission of any such demand by a Nonconsenting Limited Partner, Aimco OP shall, within 40 days after the Election Deadline, submit to the arbitration panel a duly verified list containing the names and addresses of all Nonconsenting Limited Partners who have demanded payment for their Limited Partnership Units and with whom agreements as to the value of their Limited Partnership Units have not been reached with Aimco OP. The arbitration panel shall give notice of the time and place fixed for the hearing of such demand by registered or certified mail to Aimco OP and to the Nonconsenting Limited Partners shown on the list at the addresses therein stated. The forms of the notices shall be approved by the panel, and the costs thereof shall be borne by Aimco OP.

(e) At the hearing on such demand, the panel shall determine the Nonconsenting Limited Partners who have become entitled to appraisal rights hereunder.

(f) After determining the Nonconsenting Limited Partners entitled to an appraisal, the panel shall appraise the Limited Partnership Units, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the panel shall take into account all relevant factors. Unless the panel in its discretion determines otherwise for good cause shown, interest from the effective date of the Merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge), as established from time to time during the period between the effective date of the Merger and the date of payment of the judgment. Upon application by Aimco OP or by any Nonconsenting Limited Partner entitled to participate in the appraisal proceeding, the panel may, in its discretion, proceed with the appraisal prior to the final determination of the Nonconsenting Limited Partners entitled to an appraisal. Any Nonconsenting Limited Partner whose name appears on the list submitted by Aimco OP pursuant to paragraph (d) hereof may participate fully in all proceedings until it is finally determined that such Nonconsenting Limited Partner is not entitled to appraisal rights hereunder.

(g) The panel shall direct the payment of the fair value of the Limited Partnership Units, together with interest, if any, by Aimco OP to the Nonconsenting Limited Partners entitled thereto. Payment shall be so made to each such Nonconsenting Limited Partner upon the receipt by Aimco OP of the written consent from such Nonconsenting Limited Partner that, for federal income tax purposes, the issuance of cash for the Limited Partnership Units shall be treated as a sale of the Limited Partnership Units by the owner and a purchase of such Limited Partnership Units by Aimco OP for the cash consideration so paid under the terms of the Merger Agreement in accordance with the guidelines set forth in Treas. Reg. Sections 1.708-1(c)(3) and 1.708-1(c)(4).

(h) The costs of the proceeding may be determined by the panel and taxed upon the parties as the panel deems equitable in the circumstances. Upon application of a Nonconsenting Limited Partner, the panel may order all or a portion of the expenses incurred by any Nonconsenting Limited Partner in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the interests entitled to an appraisal.

(i) From and after the effective date of the Merger, no Nonconsenting Limited Partner who has demanded appraisal rights as provided in paragraph (b) hereof shall be entitled to vote such Limited Partnership Units for any purpose or to receive payment of distributions on such interests (except distributions payable as of a record date prior to the effective date of the Merger); provided, however, that if such Nonconsenting Limited Partner shall deliver to AIMCO Properties, L.P., c/o Eagle Rock Proxy Advisors, LLC, by mail at 12 Commerce Drive, Cranford, New Jersey, 07016, or by fax at (908) 497-2349, a written withdrawal of such Nonconsenting Limited Partner’s demand for an appraisal and an acceptance of the Cash Consideration payable pursuant to the Merger Agreement, either as provided in paragraph (c) hereof or thereafter with the written approval of Aimco OP, then the right of such Nonconsenting Limited Partner to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding before the panel shall be dismissed as to any Nonconsenting Limited Partner without the approval of the panel, and such approval may be conditioned upon such terms as the panel deems just.
