Our common stock is traded on the NYSE MKT (previously known as NYSE AMEX), or NYSE MKT, under the symbol "APTS." On January 28, 2013, the last reported sale price of our common stock on the NYSE MKT was $8.20 per share.

Accredited Investor Private Placement Offering

On January 17, 2013, we entered into securities purchase agreements dated as of January 16, 2013, or the Securities Purchase Agreements, with certain accredited investors, or the Investors, pursuant to which, among other things, we sold 40,000 shares of Series B Mandatorily Convertible Cumulative Perpetual Preferred Stock, liquidation value $1,000 per share, or the Series B Mandatorily Convertible Preferred Stock, in a private placement, or the Private Placement, to the Investors in exchange for aggregate cash consideration of $40,000,000. Each share of Series B Mandatorily Convertible Preferred Stock was sold to the Investors at an offering price of $1,000 per share. We used the net offering proceeds of the Private Placement to acquire three multifamily residential properties and to refinance the existing debt on these acquired properties. The closing process and funding under many of the Securities Purchase Agreements began on January 16, 2013. However, the closings under the Securities Purchase Agreements were not consummated until January 17, 2013.

Registration Rights Agreements

In connection with the Private Placement, on January 17, 2013, we entered into a registration rights agreement dated as of January 16, 2013, or the Registration Rights Agreement, with each of the Investors. Pursuant to the terms of the Registration Rights Agreement, we agreed to file a resale registration statement by no later than April 15, 2013 for the purpose of registering the resale of the underlying shares of common stock into which the shares of Series B Mandatorily Convertible Preferred Stock are convertible (following stockholder approval of the conversion of the Series B Mandatorily Convertible Preferred Stock into shares of common stock). Pursuant to the Registration Rights Agreement, we agreed to use commercially reasonable efforts to have such registration statement declared effective with the SEC within 120 days of such filing.

Placement Agency Agreement

In connection with the Private Placement, on January 11, 2013, we entered into a placement agency agreement, or the Placement Agency Agreement, with Wunderlich Securities, Inc., a Tennessee corporation, Compass Point Research & Trading, LLC, a Delaware limited liability company, and National Securities Corporation, a Washington corporation, or the Agents. Under the Placement Agency Agreement, the Agents agreed to use their "best efforts" on an "all-or-none" basis to sell a minimum amount of 28,000 shares of Series B Mandatorily Convertible Preferred Stock, and to use their "best efforts" to sell a maximum amount of 40,000 shares of Series B Mandatorily Convertible Preferred Stock. As compensation for such services, we agreed to pay the Agents a fee of 6.0% of the aggregate gross proceeds from the sale of such equity securities and to reimburse the Agents for all reasonable, documented out-of-pocket accountable expenses incurred by them in connection with the Private Placement, up to an aggregate amount equal to $57,500.

The Placement Agency Agreement contains customary representations and warranties and covenants of the company and is subject to customary closing conditions. In addition, the company and the Agents have agreed to indemnify each other against certain

S-1

liabilities, including indemnification of the Agents by the company for liabilities under the Securities Act and for liabilities arising from breaches of the representations, warranties or obligations contained in the Placement Agency Agreement.

Promissory Note and Loss Sharing Agreement

In connection with the purchase by his affiliates of 2,639 shares of Series B Mandatorily Convertible Preferred Stock in the Private Placement, on January 17, 2013, J. Steven Emerson, or the Maker, executed a promissory note, dated January 16, 2013, or the Promissory Note, in the aggregate principal amount of $2,639,000 in favor of the company. The Promissory Note had an interest rate of 0.5% per annum, beginning January 23, 2013 and maturing on January 25, 2013. On January 18, 2013, the purchase price for the 2,639 shares of Series B Mandatorily Convertible Preferred Stock referred to above was paid in full and the Promissory Note was canceled.

In connection with the Promissory Note, on January 17, 2013, the company and the Agents entered into a loss sharing agreement dated as of January 16, 2013, or the Loss Sharing Agreement, pursuant to which the Agents agreed to acquire part of the Promissory Note from us if the Maker defaulted on the Promissory Note. The Agents agreed that the consideration for such acquisition would have been made by a reduction of the fees otherwise payable to the Agents under the Placement Agency Agreement. As a result of the cancellation of the Promissory Note on January 18, 2013, the obligation of the Agents to acquire part of the Promissory Note from the company no longer exists.

The following disclosure is added immediately preceding the section entitled "Description of Real Estate Investments — Depreciation" beginning on page S-48 of Supplement No. 3.

Liquidation Agreement

"On January 18, 2013, WMAF, WMAF GP, Williams LP, WRA and Oxford entered into the Liquidation Agreement, in connection with, among other things, the acquisition of up to three real estate investment properties: Ashford Park, Lake Cameron and McNeil Ranch, or, collectively, the Real Estate Investment Properties. We are not a party to the Liquidation Agreement. Oxford holds an indirect 95% interest, and affiliates of the company hold an indirect 5% interest, in the Real Estate Investment Properties through their ownership of WMAF.

The Liquidation Agreement provided that Williams LP had the right to exercise an option to purchase all the outstanding common stock of the separate real estate investment trusts, or the REIP Entities, that indirectly own the Real Estate Investment Properties (and thereby acquire the Real Estate Investment Properties) at the agreed-upon purchase prices included therein. The Liquidation Agreement generally is binding on the parties thereto, but the transactions contemplated thereby regarding the acquisition of the Real Estate Investment Properties were subject to certain conditions, including Williams LP giving affirmative notice of its desire to acquire all the common stock of the REIP Entities and designating our operating partnership as the purchaser of all the common stock of the REIP Entities. The Liquidation Agreement provides that the Real Estate Investment Properties will need to be acquired by January 25, 2013 for the Ashford Park and McNeil Ranch properties and March 31, 2013 for the Lake Cameron property.

On January 18, 2013, pursuant to the terms of the Option Exercise Notices, Williams LP exercised its options to purchase all the common stock of the REIP Entities and thereby acquire indirectly the ownership of the Real Estate Investment Properties, and designated our operating partnership as the purchaser of all the common stock of the REIP Entities, with a final closing date for such purchases of January 23, 2013. Further, on January 23, 2013, pursuant to the terms of stock transfer agreements, or the Stock Transfer Agreements, among our operating partnership, WMAF and WMAF GP, all the shares of common stock of the REIP Entities that indirectly own the Real Estate Investment Properties were transferred from WMAF to our operating partnership. John A. Williams, our Chief Executive Officer and Chairman, indirectly owns an approximate 1.56% interest in WMAF, Leonard A. Silverstein, our President and Chief Operating Officer and a board member, indirectly owns an approximate 0.16% interest in WMAF and William F. Leseman, our Executive Vice President – Property Management, indirectly owns an approximate 0.05% interest in WMAF. In connection with the acquisition of all of the Real Estate Investment Properties, from these indirect interests in WMAF, Mr. Williams, Mr. Silverstein and Mr. Leseman received approximately $331,175, $33,268 and $10,429, respectively. See "Risk Factors—We have affiliations with the property manager and the seller of the Real Estate Investment Properties and the terms of the acquisitions may not be as favorable to us as if they had been negotiated with an unaffiliated third party," Risk Factors- We may purchase real properties from persons with whom affiliates of our manager have prior business relationships, which may impact the purchase terms, and as a

result, affect your investment," "Risk Factors- Our manager and its affiliates receive fees and other compensation based upon our investments, which may impact operating decisions, and as a result, affect your investment," and "Risk Factors-- General Risks Related to Investments in Real Estate"

Ashford Park

On January 18, 2013, our operating partnership, under the terms the Liquidation Agreement, was designated as the Williams Purchaser (as defined in the Liquidation Agreement) and exercised its option to purchase all of the common stock of Ashford Park REIT Inc., the indirect fee-simple owner of Ashford Park. On January 23, 2013, our operating partnership closed on such purchase.

The total acquisition cost of Ashford Park was approximately $39.4 million, subject to adjustments for customary pro rations in the acquisition of real estate. The $39.4 million acquisition cost includes existing first mortgage debt of approximately $38.8 million, which has been paid in full, but excludes acquisition-related and financing-related transaction costs. In connection with the purchase of this asset, our manager received an acquisition fee equal to approximately $0.4 million. Other closing and financing related costs are expected to be approximately $1.5 million, including approximately $0.6 million for minor deferred maintenance and minor capital expenditures. In connection with the acquisition of Ashford Park, on January 24, 2013, we refinanced the existing first mortgage debt with a portion of the net proceeds from the Private Placement and with a new loan of approximately $25.6 million originated by Prudential.

Ashford Park is a multifamily community consisting of 408 units located in Atlanta, Georgia. The community consists of three buildings on a 10.6-acre landscaped setting. Ashford Park is comprised of a unit mix of 190 one-bedroom units, 182 two-bedroom units and 36 three-bedroom units. The property was constructed in 1992 and its apartment homes have an average size of 1,008 square feet. We believe the Ashford Park property is suitable and adequate for use as a multifamily apartment complex. We have no present intention to make major renovations, improvements or developments at the Ashford Park property.

There are currently ten other apartment communities in the area that we believe are competitive with Ashford Park. Including Ashford Park, these 11 communities include 4,410 units, have an average unit size of 1,036 square feet and an average year of construction of 2000. In addition to existing competitive properties, the submarket in which Ashford Park is located had no units delivered in the twelve months ended September 30, 2012 and no additional units are scheduled to be delivered through September 30, 2013. In addition to the specific competitive conditions described above, general competitive conditions affecting Ashford Park include those identified in the section entitled "Competition" included elsewhere in this prospectus.

On January 24, 2013, our subsidiary that owns Ashford Park obtained a non-recourse first mortgage loan, or the Ashford Loan, from Prudential in the original principal amount of approximately $25.6 million. Following execution of a Multifamily Loan and Security Agreement, or the Ashford Loan Agreement, and related documents, Prudential will sell, transfer, deliver and assign the Ashford Loan to the Federal Home Loan Mortgage Corporation, or the Lender. The Ashford Loan is secured by Ashford Park by a Multifamily Deed to Secure Debt, Assignment of Rents and Security Agreement, or the Ashford Mortgage. Our subsidiary that owns Ashford Park received net proceeds of approximately $25.3 million after payment of costs and fees associated with obtaining the Ashford Loan. The Ashford Loan bears interest at a fixed rate of interest equal to 3.13% per annum. The Ashford Loan requires monthly payments of accrued interest only from the period of March 1, 2013 to February 1, 2018. Beginning on March 1, 2018, the Ashford Loan will require monthly payments of accrued interest and principal based on a 30-year amortization period. All remaining indebtedness, including all interest and principal, is due by February 1, 2020. Subject to limited exceptions, our subsidiary that owns Ashford Park must pay additional charges for prepayment of any principal prior to the three-month period beginning on November 1, 2019. There are no guaranties of the Ashford Loan provided by us or our operating partnership.

In accordance with the terms of the Ashford Loan Agreement and the note related to the borrowing, the payment of the note may be accelerated at the option of the Lender if an event of default occurs. As defined in the Ashford Loan Agreement, events of default include, but are not limited to: failure to pay any amount due under the Ashford Loan Agreement or any related documents when due; failure to maintain insurance coverage required under the Ashford Loan Agreement; owning any real or personal property other than the mortgaged property and personal property related to the operation and maintenance of the mortgaged property; and any materially false or misleading representations or warranties made in connection with the Ashford Loan Agreement.

We expect that the initial basis in the property for federal income tax purposes will be equal to the purchase price. We plan to depreciate the property for federal income tax purposes on a straight-line basis using an estimated useful life of 27.5 years.

Under a contract with our manager, the property manager will act as property manager of Ashford Park. We believe Ashford Park is adequately insured.

An unaudited trailing twelve month profit and loss financial report for Ashford Park for the period ended September 30, 2012 is included as Exhibit A hereto.

Lake Cameron

On January 18, 2013, our operating partnership, under the terms of the Liquidation Agreement, was designated as the Williams Purchaser (as defined in the Liquidation Agreement) and exercised its option to purchase all of the common stock of Lake Cameron REIT Inc., the indirect fee-simple owner of Lake Cameron. On January 23, 2013, our operating partnership closed on such purchase.

The total acquisition cost of Lake Cameron was approximately $30.4 million, subject to adjustments for customary pro rations in the acquisition of real estate. The $30.4 million acquisition cost includes existing first mortgage debt of approximately $17.5 million, which has now been paid in full, but excludes acquisition-related and financing-related transaction costs. In connection with the purchase of this asset, our manager received an acquisition fee equal to approximately $0.3 million. Other closing and financing related costs are expected to be approximately $0.9 million, including approximately $0.2 million for minor deferred maintenance and

S-13

minor capital expenditures. In connection with the acquisition of Lake Cameron, on January 24, 2013, we refinanced existing first mortgage debt on Lake Cameron with a new loan of approximately $19.8 million originated by Jones Lang.

Lake Cameron is a multifamily community consisting of 328 units located in suburban Raleigh, North Carolina. The community consists of one clubhouse, 14 residential and eight garage buildings on a 23.94-acre landscaped setting. Lake Cameron is comprised of a unit mix of 128 one-bedroom units, 164 two-bedroom units and 36 three-bedroom units. The property was constructed in 1997 and its apartment homes have an average size of 940 square feet. We believe the Lake Cameron property is suitable and adequate for use as a multifamily apartment complex. We have no present intention to make major renovations, improvements or developments at the Lake Cameron property.

There are currently seven other apartment communities in the area that we believe are competitive with Lake Cameron. Including Lake Cameron, these eight communities include 2,640 units, have an average unit size of 1,051 square feet and an average year of construction of 1998. In addition to existing competitive properties, the submarket in which Lake Cameron is located had 404 units delivered in the twelve months ended September 30, 2012 and 149 additional units are scheduled to be delivered through September 30, 2013. In addition to the specific competitive conditions described above, general competitive conditions affecting Lake Cameron include those identified in the section entitled "Competition" included elsewhere in this prospectus.

On January 24, 2013, our subsidiary that owns Lake Cameron obtained a non-recourse first mortgage loan, or the Lake Cameron Loan, from Jones Lang in the original principal amount of approximately $19.8 million. Following execution of a Multifamily Loan and Security Agreement, or the Lake Cameron Loan Agreement, and related documents, Jones Lang will sell, transfer, deliver and assign the Lake Cameron Loan to the Lender. The Lake Cameron Loan is secured by Lake Cameron by a Multifamily Deed of Trust, Assignment of Rents, Security Agreement and Fixture Filing, or the Lake Cameron Mortgage. Our subsidiary that owns Lake Cameron received net proceeds of approximately $19.5 million after payment of costs and fees associated with obtaining the Lake Cameron Loan. The Lake Cameron Loan bears interest at a fixed rate of interest equal to 3.13% per annum. The Lake Cameron Loan requires monthly payments of accrued interest only from the period of March 1, 2013 to February 1, 2018. Beginning on March 1, 2018, the Lake Cameron Loan will require monthly payments of accrued interest and principal based on a 30-year amortization period. All remaining indebtedness, including all interest and principal, is due by February 1, 2020. Subject to limited exceptions, our subsidiary that owns Lake Cameron must pay additional charges for prepayment of any principal prior to the three-month period beginning on November 1, 2019. There are no guaranties of the Lake Cameron Loan provided by us or our operating partnership.

In accordance with the terms of the Lake Cameron Loan Agreement and the note related to the borrowing, the payment of the note may be accelerated at the option of the Lender if an event of default occurs. As defined in the Lake Cameron Loan Agreement, events of default include, but are not limited to: failure to pay any amount due under the Lake Cameron Loan Agreement or any related documents when due; failure to maintain insurance coverage required under the Lake Cameron Loan Agreement; owning any real or personal property other than the mortgaged property and personal property related to the operation and maintenance of the mortgaged property; and any materially false or misleading representations or warranties made in connection with the Lake Cameron Loan Agreement.

We expect that the initial basis in the property for federal income tax purposes will be equal to the purchase price. We plan to depreciate the property for federal income tax purposes on a straight-line basis using an estimated useful life of 27.5 years.

At December 31, 2007	96.6%

No single tenant occupies 10% or more of Lake Cameron.

The average historical effective net annual rental rate per unit (including any tenant concessions and abatements) at the property is as follows:

Property taxes paid on Lake Cameron for the fiscal year ended December 31, 2011 were $214,187. Lake Cameron was subject to a tax rate of .902% of its assessed value.

Under a contract with our manager, the property manager will act as property manager of Lake Cameron. We believe Lake Cameron is adequately insured.

An unaudited trailing twelve month profit and loss financial report for Lake Cameron for the period ended September 30, 2012 is included as Exhibit B hereto.

McNeil Ranch

On January 18, 2013, our operating partnership, under the terms of the Liquidation Agreement, was designated as the Williams Purchaser (as defined in the Liquidation Agreement) and exercised its option to purchase all of the common stock of McNeil Ranch REIT Inc., the indirect fee-simple owner of McNeil Ranch. On January 23, 2013, our operating partnership closed on such purchase.

The total acquisition cost of McNeil Ranch was approximately $21.0 million, subject to adjustments for customary pro rations in the acquisition of real estate. The $21.0 million acquisition cost includes existing first mortgage debt of approximately $13.4 million, which has been paid in full, but excludes acquisition-related and financing-related transaction costs. In connection with the purchase of this asset, our manager received an acquisition fee equal to approximately $0.2 million. Other closing and financing related costs are expected to be approximately $0.8 million, including approximately $0.2 million for minor deferred maintenance and minor capital expenditures. In connection with the acquisition of McNeil Ranch, we refinanced the existing first mortgage debt with a portion of the net proceeds from the Private Placement and with a new loan of approximately $13.6 million originated by Jones Lang.

McNeil Ranch is a multifamily community consisting of 192 units located in Austin, Texas. The community consists of sixteen residential buildings and one clubhouse on a 10.9-acre landscaped setting. McNeil Ranch is comprised of a unit mix of 86 one-

S-15

bedroom units, 70 two-bedroom units and 36 three-bedroom units. The property was constructed in 1999 and its apartment homes have an average size of 1,067 square feet. We believe the McNeil Ranch property is suitable and adequate for use as a multifamily apartment complex. We have no present intention to make major renovations, improvements or developments at the McNeil Ranch property.

There are currently eleven other apartment communities in the area that we believe are competitive with McNeil Ranch. Including McNeil Ranch, these 12 communities include 3,743 units, have an average unit size of 946 square feet and an average year of construction of 1999. In addition to existing competitive properties, the submarket in which McNeil Ranch is located had 244 units delivered in the twelve months ended September 30, 2012 and no additional units are scheduled to be delivered through September 30, 2013. In addition to the specific competitive conditions described above, general competitive conditions affecting Lake Cameron include those identified in the section entitled "Competition" included elsewhere in this prospectus.

    On January 24, 2013, our subsidiary that owns McNeil Ranch obtained a non-recourse first mortgage loan, or the McNeil Ranch Loan, from Jones Lang in the original principal amount of approximately $13.6 million. Following execution of a Multifamily Loan and Security Agreement, or the McNeil Ranch Loan Agreement, and related documents, Jones Lang will sell, transfer, deliver and assign the McNeil Ranch Loan to the Lender. The McNeil Ranch Loan is secured McNeil Ranch by a Multifamily Deed of Trust, Assignment of Rents, Security Agreement and Fixture Filing, or the McNeil Mortgage, and together with the Ashford Mortgage and the Lake Cameron Mortgage, the Mortgages. Our subsidiary that owns McNeil Ranch received net proceeds of approximately $13.4 million after payment of costs and fees associated with obtaining the McNeil Ranch Loan. The McNeil Ranch Loan bears interest at a fixed rate of interest equal to 3.13% per annum. The McNeil Ranch Loan requires monthly payments of accrued interest only from the period of March 1, 2013 to February 1, 2018. Beginning on March 1, 2018, the McNeil Ranch Loan will require monthly payments of accrued interest and principal based on a 30-year amortization period. All remaining indebtedness, including all interest and principal, is due by February 1, 2020. Subject to limited exceptions, our subsidiary that owns McNeil Ranch must pay additional charges for prepayment of any principal prior to the three-month period beginning on November 1, 2019. There are no guaranties of the McNeil Ranch Loan provided by us or our operating partnership.

In accordance with the terms of the McNeil Ranch Loan Agreement and the note related to the borrowing, the payment of the note may be accelerated at the option of the Lender if an event of default occurs. As defined in the McNeil Ranch Loan Agreement, events of default include, but are not limited to: failure to pay any amount due under the McNeil Ranch Loan Agreement or any related documents when due; failure to maintain insurance coverage required under the McNeil Ranch Loan Agreement; owning any real or personal property other than the mortgaged property and personal property related to the operation and maintenance of the mortgaged property; and any materially false or misleading representations or warranties made in connection with the McNeil Ranch Loan Agreement.

We expect that the initial basis in the property for federal income tax purposes will be equal to the purchase price. We plan to depreciate the property for federal income tax purposes on a straight-line basis using an estimated useful life of 27.5 years.

All the leased space is residential with leases ranging from an initial term of six months to one year. The average historical occupancy rate (determined by the total number of units actually occupied at the specific point in time indicated) for the last five years is as follows:

At December 31, 2011	97.4%
At December 31, 2010	94.8%
At December 31, 2009	90.6%
At December 31, 2008	90.6%
At December 31, 2007	94.3%

No single tenant occupies 10% or more of McNeil Ranch.

S-16

The average historical effective net annual rental rate per unit (including any tenant concessions and abatements) at the property is as follows:

Year ending December 31, 2011	$12,628
Year ending December 31, 2010	$12,061
Year ending December 31, 2009	$12,231
Year ending December 31, 2008	$12,542
Year ending December 31, 2007	$12,073

Property taxes paid on McNeil Ranch for the fiscal year ended December 31, 2011 were $411,296. McNeil Ranch was subject to a tax rate of 2.475% of its assessed value.

Under a contract with our manager, the property manager will act as property manager of McNeil Ranch. We believe McNeil Ranch is adequately insured.

An unaudited trailing twelve month profit and loss financial report for McNeil Ranch for the period ended September 30, 2012 is included as Exhibit C hereto.

The following disclosure is added immediately preceding the section entitled, "Description of Securities – Common Stock Warrants" on page 155 of the Prospectus.

"Series B Mandatorily Convertible Preferred Stock

Our board of directors, including our independent directors, has created out of the authorized and unissued shares of our preferred stock, a series of preferred stock, designated as the Series B Mandatorily Convertible Preferred Stock.

The following is a brief description of the terms of our Series B Mandatorily Convertible Preferred Stock, which was offered to certain investors in the Private Placement described above. The description of our Series B Mandatorily Convertible Preferred Stock contained herein does not purport to be complete and is qualified in its entirety by reference to the Articles Supplementary for our Series B Mandatorily Convertible Cumulative Perpetual Preferred Stock, which has been filed with the SEC as exhibit 4.1 to that certain Current Report on Form 8-K, filed with the SEC on January 23, 2013.

Rank: The Series B Mandatorily Convertible Preferred Stock ranks senior to our common stock and to the Class A Units and Class B Units issued by our operating partnership and on a paritywith the Series A Redeemable Preferred Stock, the Series A Redeemable Preferred Limited Partnership Units issued by our operating partnership and the Series B Mandatorily Convertible Preferred Stock issued by our operating partnership with respect to payment of dividends and distribution of amounts upon liquidation, dissolution or winding up.

Stated Value: Each share of Series B Mandatorily Convertible Preferred Stock has a "Stated Value" of $1,000.

Dividends: Subject to the preferential rights of the holders of any class or series of our capital stock ranking senior to the Series B Mandatorily Convertible Preferred Stock, if any such class or series is authorized in the future, the holders of Series B Mandatorily Convertible Preferred Stock are entitled to receive, when, and if authorized by our board of directors and declared by us out of legally available funds, a dividend, on an as converted basis, that mirrors any dividend payable on shares of our common stock and also will be entitled to share in any other distribution made on our common stock on an as converted basis (other than dividends or other distributions payable in our common stock), for the period beginning with any dividends and other distributions in respect of the

S-18

first quarter of 2013. Any dividends or other distributions on the Series B Mandatorily Convertible Preferred Stock for the first quarter of 2013 will be paid, on an as converted basis, pro rata from the date of issuance.

For the period beginning on May 16, 2013, but only to the extent that the Series B Mandatorily Convertible Preferred Stock remains outstanding during this period and subject to the preferential rights of holders of any shares of senior capital stock of the company, each share of the Series B Mandatorily Convertible Preferred Stock will bear a dividend, when and as authorized by the Board of Directors, equal to the excess, if any, of (i) 15.0% per annum, minus (ii) any dividend or other distribution payable by us on the Series B Mandatorily Convertible Preferred Stock pursuant to the previous paragraph in respect of the applicable quarterly period. Such dividends shall be cumulative from May 16, 2013 and shall be payable quarterly in arrears on or before July 15th, October 15th, January 15th and April 15th of each year or, if not a business day, the next succeeding business day.

Mandatory Conversion: The Series B Mandatorily Convertible Preferred Stock will automatically convert into shares of our common stock on the later of (a) the close of business on the fifth business day and (b) approval of our listing application for such shares of our common stock by the NYSE MKT, in both cases, following the approval by the requisite holders of our common stock of the conversion of the Series B Mandatorily Convertible Preferred Stock into common stock and the issuance of common stock upon such conversion. Each share of Series B Mandatorily Convertible Preferred Stock shall convert into that number of shares of our common stock equal to (i) the sum of the Stated Value and all accrued and unpaid dividends thereon, divided by (ii) the conversion price of $7.00 per share, subject to adjustment as described below.

Adjustment. If the company, at any time prior to the conversion of the Series B Mandatorily Convertible Preferred Stock into shares of our common stock, (i) pays a dividend or make a distribution on the outstanding shares of its common stock payable in its common stock, (ii) subdivides the outstanding shares of its common stock into a larger number of shares, (iii) combines the outstanding shares of its common stock into a smaller number of shares, or (iv) issues any shares of its capital stock in a reclassification, recapitalization or other similar event affecting its common stock (subject to certain exceptions as specified in the Articles Supplementary for Series B Mandatorily Convertible Preferred Stock), then the conversion price in effect immediately prior to such event shall be adjusted (and/or any other appropriate actions shall be taken by the company) so that the holder of any share of Series B Mandatorily Convertible Preferred Stock thereafter converted shall be entitled to receive the number of shares of our common stock or other securities of the company that such holder would have owned or would have been entitled to receive upon or by reason of any of the events described above, had such share of Series B Mandatorily Convertible Preferred Stock been converted immediately prior to the occurrence of such event. No fractional adjustments shall be made in an amount of less than one cent per share.

Voting Rights: Holders of the Series B Mandatorily Convertible Preferred Stock generally will have no voting rights, unless their preferred dividends are in arrears for six or more quarterly periods (whether or not consecutive). Whenever such a preferred dividend default exists, holders of Series B Mandatorily Convertible Preferred Stock, voting as a single class with the holders of any other class or series of our preferred stock having similar voting rights, have the right to elect two additional directors to the Board of Directors. This right continues until all dividends accumulated on the Series B Mandatorily Convertible Preferred Stock have been fully paid or authorized and declared and a sum sufficient for the payment thereof set aside for payment. The term of office of each director elected by the holders of Series B Mandatorily Convertible Preferred Stock expires upon cure of the preferred dividend default.

The affirmative vote or consent of the holders of at least two-thirds of the outstanding shares of Series B Mandatorily Convertible Preferred Stock, voting as a single class, shall be required to authorize, create, increase the number of or issue any shares of capital stock of the company that are senior to the Series B Mandatorily Convertible Preferred Stock or any security convertible into our capital stock that is senior to the Series B Mandatorily Convertible Preferred Stock or reclassify any other existing shares of our capital stock of into shares of our capital stock that are senior to the Series B Mandatorily Convertible Preferred Stock.

S-19

Stock would have been convertible immediately prior to the day fixed for redemption, which value shall be calculated on the volume weighted average price of our common stock for the 20 trading days prior to the day fixed for redemption; or (ii) if the redemption occurs after the first anniversary of the issuance of the Series B Mandatorily Convertible Preferred Stock, the greater of (A) 100% of the liquidation preference plus all accrued and unpaid dividends; and (B) 100% of the value of that number of shares of our common stock into which such share of Series B Mandatorily Convertible Preferred Stock would have been convertible immediately prior to the day fixed for redemption, which value shall be calculated on the volume weighted average price of our common stock for the 20 trading days prior to the day fixed for redemption.

Liquidation Preference. Upon any voluntary or involuntary liquidation, dissolution or winding-up of our affairs, before any distribution or payment shall be made to holders of our common stock or any other class or series of capital stock ranking junior to our shares of Series B Mandatorily Convertible Preferred Stock, the holders of shares of Series B Mandatorily Convertible Preferred Stock will be entitled to be paid out of our assets legally available for distribution to our stockholders, after payment or provision for our debts and other liabilities, a liquidation preference equal to the Stated Value per share, plus an amount equal to any accrued and unpaid dividends (whether or not declared) to and including the date of payment.

After payment of the full amount of the liquidating distributions to which they are entitled, the holders of our shares of Series B Mandatorily Convertible Preferred Stock will have no right or claim to any of our remaining assets. Our consolidation or merger with or into any other corporation, trust or other entity, the consolidation or merger of any other corporation, trust or entity with or into us, the sale or transfer of any or all our assets or business, or a statutory share exchange will not be deemed to constitute a liquidation, dissolution or winding-up of our affairs.

In determining whether a distribution (other than upon voluntary or involuntary liquidation), by dividend, redemption or other acquisition of shares of our stock or otherwise, is permitted under the MGCL, amounts that would be needed, if we were to be dissolved at the time of distribution, to satisfy the preferential rights upon dissolution of holders of the Series B Mandatorily Convertible Preferred Stock will not be added to our total liabilities.

Exchange Listing: We do not plan on making an application to list the shares of Series B Mandatorily Convertible Preferred Stock on NYSE MKT, any other national securities exchange or any other nationally recognized trading system."

The following disclosure is added immediately following the first paragraph under the heading, "Description of Securities -- Distribution Policy and Distributions" on page 158 of the Prospectus.

"Foreign Accounts

Withholding taxes may apply to certain types of payments made to "foreign financial institutions" (as specially defined in the Code) and certain other non-U.S. entities. A withholding tax of 30% generally will be imposed on dividends on, and gross proceeds from the sale or other disposition of, our common stock paid to (a) a foreign financial institution unless such foreign financial institution agrees to verify, report and disclose its U.S. accountholders and meets certain other specified requirements or (b) a non-financial foreign entity that is the beneficial owner of the payment unless such entity certifies that it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner and such entity meets certain other specified requirements. Applicable Treasury Regulations provide that these rules generally will apply to payments of dividends on our common stock made after December 31, 2013 and generally will apply to payments of gross proceeds from a sale or other disposition of our common stock after December 31, 2016. We will not pay any additional amounts in respect of any amounts withheld. U.S. Stockholders and Non-U.S. Stockholders are encouraged to consult their tax advisors regarding the particular consequences to them of this legislation and guidance."
