NicOx S.A. (NYSE Euronext Paris: COX) today announces that it has entered into an agreement to acquire 11.8% of the shares of Altacor, a privately-held ophthalmology company based in the United Kingdom, and entered into an exclusive option agreement to acquire the remaining shares of Altacor, marking the first step in its strategic plan to become a latestage development and commercial ophthalmology company.

Altacor’s primary focus has been to build a specialty pharmaceutical company and has products, pipeline and

relationships in place to  advance this significantly with NicOx. Altacor markets prescription and over-the-counter (OTC)

products for the treatment of dry eye in the  United Kingdom and Ireland and  has a  diversified late-stage pipelineincluding ALT-005, a surgical antiseptic, and SOLO, a device for the insertion of IntraOcular Lenses (IOLs). Under the terms of the agreement, NicOx (the “Company”) is investing £2 million (approximately €2.4 million) in cash to acquire an initial  11.8% stake in  Altacor. In addition, NicOx has been granted an exclusive  call option to acquire the remaining shares of Altacor for an additional consideration of £9 million (approximately €10.8 million

(1) to be paid in NicOx shares,

cash or a combination of cash and shares at NicOx’s discretion. This option may be exercised by NicOx up until May 31, 2012. If agreed milestones are met, the consideration will be increased by up to £8.5 million.

NicOx’s strategic move to become an international ophthalmology company NicOx has been assessing a number of opportunities to build on its cash position in order to create long-term value for its shareholders. The ophthalmology market is experiencing significant growth and  the Company believes this therapeutic area  offers potential to create a mid-sized  international specialist pharmaceutical company.  The global ophthalmic market was valued at $16.2 billion in 2010 and is expected to reach $21.1 billion by 2016, growing at an average rate of

4.5% per annum

(2)

  NicOx has  already  gained significant expertise in ophthalmology through  its  collaborations  with

Bausch + Lomb, Pfizer, and a network of leading advisors and key opinion leaders (KOLs).

If NicOx decides to exercise its option to acquire all of the shares of Altacor, the acquisition would bring an experienced  commercial management team  and a  marketing platform supporting sales in the  UK and Ireland as a first step from which  to  build a presence in other EU countries.  Altacor also  offers  a near-term pipeline  and key partnerships  with leading specialist companies.

NicOx’s goal is to build a  diversified  late-stage  ophthalmology  portfolio with a clear route to  commercialization. The Company is currently evaluating a number of additional  ophthalmic acquisition and in-licensing opportunities, including therapeutics, diagnostics and devices, both in the United States and in Europe.

Michele Garufi, Chief Executive Officer of NicOx,  commented: “The execution of this  transaction is the first step in  executing  our strategy to become an  international ophthalmology company. NicOx is impressed by the skills and expertise within  Altacor, which brings marketed products, international leading partners and an innovative late-stage pipeline. If we exercise the option, the acquisition  of Altacor will also provide NicOx with an established infrastructure supporting sales in the UK and Ireland as a base for the future launch of additional products.“The positive top line results from the phase 2b study conducted with BOL-303259-X by Bausch + Lomb in patients with

open-angle glaucoma or ocular hypertension announced recently have significantly strengthened our potential position in the field of ophthalmology. Altacor is the first step  towards an expansion in the ophthalmic  market through future acquisitions and in-licensing of additional assets as a basis for our growth in Europe and  in the United States. We are making progress in our evaluation of other opportunities to achieve our goals.”

Dr  Fran Crawford,  CEO of  Altacor,  said: “Altacor and NicOx have  developed  a strong working  relationship. The companies are  strategically well aligned, both having similar perspectives on the emerging ophthalmology market. We therefore believe NicOx is an excellent partner for Altacor and the investment announced today will enable us to secure the development of the portfolio, including our lead candidate ALT-005. NicOx’s R&D and partnering expertise will be of significant benefit as we progress our late-stage pipeline.”

About Altacor

Altacor is a private specialist ophthalmology company founded in 2007 and based in Cambridge, UK. Altacor’s marketing platform in the UK and in Ireland for the commercialization of the Clinitas dry eye products is well established. The overall sales of the Clinitas products, which were launched between 2007 and 2011, reached approximately £660,000 in 2011 and  are growing rapidly. They cover mild to severe dry eye through a complete action on the three layers of the tear film, with three  OTC products (Clinitas Soothe®, Clinitas Hydrate® and Clinitas Ultra 3®) and two prescription products (Clinitas™ and Clinitas Gel™). Clinitas Soothe® and Clinitas™ feature the highest concentration of hyaluronic  acid (0.4%) available for external ophthalmic use in the UK and benefit from a preservative-free formulation.

The most advanced  assets and the key drivers identified for  the future growth of  Altacor’s revenues are ALT-005, a surgical antiseptic for ocular infection, and SOLO, a device for the insertion of IOLs:

ALT-005 is being developed by Altacor as a surgical pre-operative antiseptic solution specifically for ophthalmic use. The potential market for this product is  correlated with the large number of ocular surgeries  performed

worldwide. For instance, it is estimated that there will be more than  16 million cataract surgeries  globally in

2012

(3)

and more than 1.8 million intravitreal injections were reported in the United States for the 12-month

period ending October 2011

(4)

A phase 3 study was  recently initiated in the United States with ALT-005, with

the second phase 3 study being planned later this year. Altacor plans to file an application for approval of ALT-

005  in selected EU countries and in  the  United States, where ALT-005 is partnered with a U.S. specialty

company.

 SOLO is a device for the insertion of  advanced materials  IntraOcular Lenses (IOLs) licensed exclusively  by

Altacor from Ophthalmopharma  in  July 2011. Worldwide IOL sales were expected to  reach $2.35 billion  in

2011

(3)

 STAAR Surgical (STAAR), a U.S. company specializing in lenses for ophthalmic surgery, was recently

granted non-exclusive worldwide rights for the commercialisation of SOLO. STAAR currently expects to apply

for a CE mark later this year in Europe. A U.S. filing is also planned at a later stage.
