On April 26, 2012, Genomma Lab Internacional, S.A.B. de C.V. issued the following press release and filed it with the Comisión Nacional Bancaria y de Valores (Mexican National Banking and Securities Commission):

GENOMMA LAB INTERNACIONAL'S BOARD OF DIRECTORS

UNANIMOUSLY REAFFIRMS ITS INTEREST TO ACQUIRE PRESTIGE BRANDS HOLDINGS FOR $16.60 PER SHARE IN CASH

Genomma Lab Internacional, S.A.B. de C.V. ("Genomma") (BMV: LAB.B.) today announced that its Board of Directors has unanimously reaffirmed Genomma's interest to acquire all of the outstanding shares of Prestige Brands Holdings, Inc. ("Prestige") (NYSE: PBH) common stock for $16.60 per share in cash.

Genomma's offer represents a 23% premium over Prestige's closing stock price and a 47% premium to the three-month historical average of Prestige's stock price, both as of February 17, 2012 – the last trading day prior to Genomma announcing its plan to acquire all issued and outstanding shares of Prestige.  The offer also represents an EV/EBITDA 2012e multiple of 9.3x.

Since Genomma's initial proposal to Prestige on February 21, 2012, Genomma has satisfied Prestige's conditions by:

·   Securing an understanding with regards to committed financing for the transaction from prominent financial institutions; and

·   Receiving approval for the offer from Genomma's shareholders.

Genomma intends to make public in short order a presentation highlighting the compelling value proposition it has presented to Prestige's shareholders and rebutting the unfounded and unsubstantiated allegations Prestige management has made in respect of Genomma's proposal intended to entrench the position of management at the expense of shareholders.

Rodrigo Herrera, Genomma's chief executive officer, said, "We remain firmly committed to pursuing a transaction to acquire all of the outstanding shares of common stock of Prestige.  As I have said before, we are fully prepared at any time to meet with representatives of Prestige to negotiate a mutually acceptable transaction.  I am completely convinced that meeting will prove to be highly beneficial to both Prestige and Genomma as the combination of our two companies offers compelling value to shareholders and provides a unique opportunity to bring together two world-class brand portfolios under our proven ability to market and develop brands and products."

About Genomma

Genomma is one of the fastest growing over-the-counter pharmaceutical and personal care products companies in Mexico, offering more than 73 brands, many of which are leaders in their product categories.  Genomma has extensive in-house product development capabilities that it uses to develop trusted and established brands.  Genomma's top-selling brands occupy a "top-of-mind" position for many consumers.  These top-selling brands are supported by a broad portfolio of products which largely target large, high-growth over-the-counter pharmaceutical and personal care markets.  For more information, visit www.genommalab.com.
