Securities Purchase Agreements

On March 19, 2015, Wheeler Real Estate Investment Trust, Inc., a Maryland corporation (the “Company”) entered into securities purchase agreements dated as of March 19, 2015 (the “Securities Purchase Agreements”), with certain accredited investors (the “Investors”), pursuant to which, among other things, the Company sold an aggregate of 93,000 shares of Series C Mandatorily Convertible Cumulative Perpetual Preferred Stock, liquidation value $1,000 per share (the “Series C Preferred Stock”), in a private placement (the “Private Placement”) to the Investors in exchange for aggregate consideration of $93,000,000, consisting of $90,000,000 in cash and $3,000,000 in debt reduction. Each share of Series C Preferred Stock was sold to the Investors at an offering price of $1,000 per share. The Company expects to use the net offering proceeds to acquire properties, including certain retail properties (the “Real Estate Investment Properties”), and for general working capital.

Series C Preferred Stock

The preferences, limitations, powers and relative rights of the Series C Preferred Stock are set forth in the Articles Supplementary of the Company (the “Articles Supplementary”). The Articles Supplementary were filed as Exhibit 3.1 to the Company’s Current Report on Form 8-K filed on March 18, 2015.

The Series C Preferred Stock ranks senior to the Company’s common stock (the “Common Stock”) and pari passu with the Company’s Series A Preferred Stock and Series B Convertible Preferred Stock with respect to payment of dividends and distribution of amounts upon liquidation, dissolution or winding up. Each share of Series C Preferred Stock has a “Stated Value” of $1,000.

From March 19, 2015 until June 18, 2015, the holders of Series C Preferred Stock are entitled to receive, when, and if authorized by the Company’s board of directors (the “Board of Directors”) and declared by the Company out of legally available funds, a dividend, on an as converted basis, that mirrors any dividend payable on shares of Common Stock and also will be entitled to share in any other distribution made on the Common Stock on an as converted basis (other than dividends or other distributions payable in Common Stock. Any dividends or other distributions on the Series C Preferred Stock during this time period will be paid, on an as converted basis, pro rata from the date of issuance.

1

In addition, for the period beginning on and including June 19, 2015, but only to the extent that the Series C Preferred Stock remains outstanding and subject to the preferential rights of holders of any shares of senior capital stock of the Company, each share of the Series C Preferred Stock will bear a dividend, when and as authorized by the Board of Directors of the Company, equal to the excess, if any, of (i) 15.0% per annum, minus (ii) any dividend or other distribution payable by the Company on the Series C Preferred Stock pursuant to the previous paragraph in respect of the applicable quarterly period. Such dividends shall be cumulative from June 19, 2015 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. If the Series C Preferred Stock is converted to Common Stock prior to June 19, 2015, then no additional dividends will be payable on the Series C Preferred Stock.

The Series C Preferred Stock will automatically convert into shares of Common Stock on the fifth business day following the approval by the requisite holders of the Common Stock of the conversion of the Series C Preferred Stock into Common Stock and the issuance of Common Stock upon such conversion. Each share of Series C Preferred Stock shall convert into that number of shares of 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 $2.00 per share, subject to adjustment as described in the Articles Supplementary.

Holders of the Series C 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, the Series C Preferred Stock stockholders, voting as a single class with the holders of any other class or series of the Company’s 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 C 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 C 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 C 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 C Preferred Stock or any security convertible into capital stock of the Company that is senior to the Series C Preferred Stock or reclassify any other existing shares of capital stock of the Company into shares of capital stock of the Company that are senior to the Series C Preferred Stock.

2

The Series C Preferred Stock is redeemable by the Company, in whole or in part at any time and from time to time, at a redemption price per share of the Series C Preferred Stock equal to (i) if the redemption occurs on or prior to the first anniversary of the issuance of the Series C Preferred Stock, the greater of (A) 105% of the liquidation preference plus all accrued and unpaid dividends, and (B) 105% of the value of that number of shares of Common Stock into which such share of Series C 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 the 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 C 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 Common Stock into which such share of Series C 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 the Common Stock for the 20 trading days prior to the day fixed for redemption.

If any of the shares of Series C Preferred Stock remain outstanding on March 19, 2018, the Company is obligated to redeem all such shares of Series C Preferred Stock in cash in an amount equal to the Stated Value plus all accrued and unpaid dividends to and including the maturity date. If the Company fails to redeem all of the Series C Preferred Stock on March 19, 2018, in addition to dividends due, the redemption price shall bear interest at the rate of one percent (1%) per month, prorated for partial months, compounded monthly, until paid in full.

Except as noted below, the Company does not plan on making an application to list the shares of Series C Preferred Stock on the Nasdaq Capital Market, any other national securities exchange or any other nationally recognized trading system unless the Company does not receive stockholder approval for the conversion of the Series C Preferred Stock into Common Stock. The Common Stock is listed on Nasdaq Capital Market under the symbol “WHLR.”

Registration Rights Agreements

In connection with the Private Placement, on March 19, 2015, the Company entered into a registration rights agreement dated as of March 19, 2015 (the “Registration Rights Agreement”), with each of the Investors. Pursuant to the terms of the Registration Rights Agreement, the Company has agreed to file a resale registration statement by no later than May 4, 2015 for the purpose of registering the resale of the underlying shares of Common Stock into

which the shares of Series C Preferred Stock are convertible (following stockholder approval of the conversion of the Series C Preferred Shares into shares of Common Stock). Pursuant to the Registration Rights Agreement, the Company has agreed to use its commercially reasonable efforts to have such registration statement declared effective with the Securities and Exchange Commission (the “SEC”) within 120 days of such filing. In the event the holders of the Company’s stockholders do not vote to approve the conversion of the Series C Preferred Stock into Common Stock at the next annual meeting of the Common Shareholders to be held on or about June 4, 2015, the Company will use its best efforts to effect the listing of the Series C Preferred Stock on the Nasdaq Capital Market. In addition, the Company shall prepare and file one or more registration statements for the purpose of registering the resale of all of the Series C Preferred Stock by the holders thereof if the Company lists the Series C Preferred Stock.

Placement Agency Agreement

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 50,000 shares of Series C Preferred Stock, and to use their “best efforts” to sell a maximum amount of 90,000 shares of Series C Preferred Stock. As compensation for such services, the Company agreed to (a) pay the Agents a fee of 6.0% of the aggregate gross proceeds from the sale of such equity securities that are to be purchased with cash, and to (b) 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 $500,000. 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 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.
