Item 1.01. Entry into a Material Definitive Agreement.

On September 30, 2011, Weingarten Realty Investors (“the Company”), a Texas real estate investment trust, entered into a $500,000,000 unsecured revolving credit facility pursuant to an Amended and Restated Credit Agreement (the “Credit Agreement”) with J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as joint bookrunners and co-arrangers, JPMorgan Chase Bank, N.A., as administrative agent, Bank of America, N.A., as syndication agent, Wells Fargo Bank, National Association, PNC Bank, National Association, and Regions Bank as documentation agents, Royal Bank of Canada as co-documentation agent, and Compass Bank, U.S. Bank National Association, and The Bank of Nova Scotia as managing agents. Other lenders involved in this transaction include Capital One, N.A., The Northern Trust Company, and Sumitomo Mitsui Banking Corporation.

The Credit Agreement is a $500,000,000 unsecured revolving credit facility with floating borrowing rates at a margin over LIBOR plus a facility fee. The borrowing margin and facility fee are priced off a grid in accordance with the Company’s senior unsecured credit ratings. The term of the credit facility ends on September 30, 2015, with a provision to extend the maturity date up to one year. The Credit Agreement contains a competitive bid option feature that will allow the Company to request bids for up to $250 million. Additionally, the Credit Agreement contains an accordion feature which allows the Company the opportunity to increase the facility amount up to $700 million. The Company intends to use the proceeds from such facility to fund any acquisition or new development activities, and for general corporate purposes.

Pursuant to the terms of the Credit Agreement, the Company is subject to requirements including covenants requiring the maintenance of (i) maximum leverage ratios on both unsecured and secured debt and (ii) unsecured interest expense and fixed charge coverage ratios. The Credit Agreement also contains customary representations and warranties, affirmative covenants, notice provisions, and events of default, including change of control, cross-defaults to other debt, and judgment defaults. Certain wholly-owned subsidiaries of the Company are guarantors of the Company’s obligations under the Credit Agreement.

The description herein of the Credit Agreement is qualified in its entirety, and the terms therein are incorporated herein, by reference to the Credit Agreement, the form of which is filed as Exhibit 10.1 hereto.
