This Amendment No. 7 (“Amendment No. 7”) amends and supplements the Tender Offer Statement on Schedule TO filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 26, 2013 and amended on April 4, 2013 and April 5, 2013, April 12, 2013, April 22, 2013, April 23, 2013 and April 24, 2013 (as amended, the “Schedule TO”) and relates to the offer of Odysseus Acquisition Corp., a Delaware corporation (the “Purchaser”), to purchase all outstanding shares of common stock, par value $0.001 (the “Shares”), of Obagi Medical Products, Inc., a Delaware corporation (“Obagi”), at a price of $24.00 per Share, net to the seller in cash, without interest (less any required withholding taxes) (the “Offer Price”), upon the terms and subject to the conditions set forth in the Offer to Purchase, dated March 26, 2013 (together with any amendments or supplements thereto, the “Offer to Purchase”) and in the related Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”), which are annexed to and filed with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively. The Purchaser is a wholly owned subsidiary of Valeant Pharmaceuticals International, a Delaware corporation (“VPI”), which is a wholly owned subsidiary of Valeant Pharmaceuticals International, Inc., a Canadian corporation (“Valeant”). This Amendment No. 7 is being filed on behalf of VPI, Valeant and the Purchaser.

All the information set forth in the Offer to Purchase, to the extent incorporated by reference therein, is hereby amended and supplemented as set forth below. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Offer to Purchase.

ITEM 11. ADDITIONAL INFORMATION

Item 11 of the Schedule TO is hereby amended and supplemented by adding the following text thereto:

“The Offer expired at 12:00 midnight, New York City time, on April 25, 2013. The Depositary for the Offer has advised VPI and the Purchaser that, as of the expiration of the Offer, a total of 14,708,133 Shares had been validly tendered into and not withdrawn from the Offer, representing approximately 84.12% of the 17,484,138 outstanding Shares as of 12:00 midnight, New York City time, on April 25, 2013. Additionally, the Depositary has advised VPI and the Purchaser that an additional 938,189 Shares had been tendered by notice of guaranteed delivery. The Purchaser has accepted for payment all Shares validly tendered into the Offer and not properly withdrawn.

Pursuant to the terms of the Merger Agreement, the Purchaser intends to exercise its option to purchase at a purchase price of $24.00 per Share directly from Obagi an additional number of Shares sufficient to give the Purchaser ownership of at least 90% of Obagi’s then outstanding Shares (on a fully diluted basis), when combined with the Shares purchased by the Purchaser in the Offer.

Following the purchase of Shares in the Offer and the issuance of Shares pursuant to the Top-Up Option, the Purchaser will have sufficient voting power to approve the Merger without the affirmative vote of any other stockholder of Obagi. Accordingly, the Purchaser and VPI intend to consummate a short-form merger in which the Purchaser will merge with and into Obagi, with Obagi surviving the Merger and continuing as a wholly-owned subsidiary of VPI. As a result of the Merger, each Share issued and outstanding immediately prior to the Effective Time, other than (i) Shares owned, directly or indirectly, by VPI or the Purchaser immediately prior to the Effective Time or held by Obagi immediately prior to the Effective Time, all of which will be cancelled and cease to exist, and (ii) Shares held by stockholders of Obagi who properly exercised their appraisal rights under Section 262 of the DGCL, will be converted into the right to receive an amount of cash equal to the Offer Price, without interest (less any applicable withholding taxes). All Shares that are converted into the right to receive the Offer Price will be canceled and cease to exist. Promptly following consummation of the Merger, VPI intends to cause all Shares to be delisted from the Nasdaq and deregistered under the Exchange Act.

On April 25, 2013, Valeant issued a press release announcing the expiration and results of the Offer. The full text of the press release is attached as Exhibit (a)(5)(H) to the Schedule TO and is incorporated herein by reference.”
