Hello everyone. My name is Luke Kissam, and I am the President and CEO of Albemarle Corporation. I want to take this opportunity to introduce myself and our company to you. I also want to tell you why the combination of Albemarle and Rockwood is so exciting and talk a little about how we will work together to build a larger, stronger and more sustainable company.

I want to start the same way we start every meeting at Albemarle – by talking about safety and environmental stewardship. There is nothing more important at Albemarle than making sure that every day every employee returns home safely to our loved ones and making sure we have a positive impact in the communities where we operate. One of the first things I noticed about the Chemetall and Rockwood Lithium businesses is that we share these core values. Going forward, we will work together to set goals that challenge us to do even better – to meet higher standards and have a positive impact on all of our stakeholders.

Albemarle is a leading global developer, manufacturer and marketer of specialty chemicals. Today, we operate two businesses, Catalyst Solutions and

Performance Chemicals, which are both leaders in their respective markets. In our catalysts business, we sell customized solutions to customers – much like you do in your Chemetall Surface Treatment business. Our catalysts are central to the production of thousands of end products in the refining and petrochemical markets. The centerpiece of our Performance Chemicals business is bromine. In that business, we have strategically located assets that provide access to the world’s lowest cost production of bromine –similar to the access Rockwood Lithium has to lithium reserves. Like Rockwood Lithium, we derivatize the bromine into higher value performance products for use in fire safety, oilfield drilling, pharmaceutical manufacturing, high-tech cleaning, water treatment and food safety.

Rockwood is a company we have long admired. As we have learned more about your organization, we have developed an even deeper appreciation for the strength of your culture and the depth of your expertise. In addition to our shared commitment to the communities where we operate, we also share a strong commitment to employees, a focus on innovation, superior customer service, and high standards for performance and execution.

From a strategic standpoint, there is no question that Albemarle and Rockwood are a great fit. The combination of these two companies is all about growth – we

will create one of the world’s largest specialty chemical companies with leading positions across our four high-margin growth businesses – lithium, catalysts, bromine, and surface treatment. Together, we will leverage complementary assets, shared knowledge and expertise, and unmatched innovation to meet our customers’ toughest challenges and deliver valuable solutions the right way. We expect that employees from both companies will benefit from increased opportunities as part of a larger, stronger organization with increased global scale.

Bringing our companies together will lead to many great things, but completing the combination is likely to take until the end of the first quarter of 2015 by which time we expect to receive all necessary regulatory approvals. Until that time, Albemarle and Rockwood will continue to operate as separate companies. It’s “business as usual” — we all have to remain focused on safety and on doing what we do best: continuing to fulfill our commitments to customers as they have come to expect from both of our organizations.

In the meantime, I am looking forward to meeting you and getting to know your organization even better. I am sure you have questions about what the future holds, and we will do our best to communicate openly with you as we work through the integration process and join forces as one company. To begin that

process and ensure that we are prepared to operate as one company upon closing, we are immediately establishing an integration team made up of dedicated employees from both companies with a goal of bringing the best both of us have to offer to the future. In the coming weeks and months, we will share more information regarding the progress that team is making.

I want to thank you for your time and reiterate how excited we are about this combination and the many opportunities ahead of us.

Until we talk again, Be Safe.
