Invisa Announces Non-binding Letter of Intent to Acquire Uniroyal

SARASOTA, FL – March 14, 2014 – Invisa, Inc. (OTCQB: “INSA”), Uniroyal Engineered Products, LLC and Engineered Products Acquisition Limited jointly announced today the execution of a non-binding Letter of Intent. Under the Letter of Intent, Invisa will acquire all of the outstanding capital stock of Uniroyal Engineered Products and Wardle Storeys Limited in exchange for newly issued shares of Invisa non-convertible preferred stock. The number of current outstanding shares of Invisa common stock will not be altered by the proposed transaction.

Upon completion of the acquisition, Invisa will have in excess of 500,000 square feet of manufacturing space, 500 employees and approximately $100 million in revenue.

According to Edmund C. King, Invisa’s CEO, “This is a significant step toward transforming Invisa into a sustainable and profitable growth company. We are thrilled to have the opportunity to bring these strong operating businesses and superior management into Invisa.”

Howard R. Curd, CEO of Uniroyal said, “We are indeed proud of Uniroyal’s operating history and brand loyalty in the textured coatings industry. With our expansion earlier this year into the UK through our acquisition of Wardle Storeys and the transaction described in the Letter of Intent announced today, I believe that we will be well-positioned to accelerate and maximize potential growth opportunities.”

The consummation of the transactions contemplated by the Letter of Intent is subject to numerous material conditions including execution by the parties of a definitive agreement and ongoing due diligence.
