Chairman and CEO Robert L. Wood —

Middlebury, CT and Indianapolis, IN, March 9, 2005 –Crompton Corporation (NYSE: CK) and Great Lakes Chemical Corporation (NYSE: GLK) announced today that they have entered into a definitive merger agreement for an all-stock merger transaction, which will create the third-largest publicly traded U.S. specialty chemicals company. The new company will have combined pro forma 2004 revenues of more than $4.1 billion and a market capitalization of nearly $3.2 billion. It will hold leading positions in high-value specialty chemical niche businesses including plastics additives, petroleum additives, flame retardants and pool chemicals. Additionally, the combined company will maintain strong positions in castable urethanes and crop protection chemicals.

Under terms of the agreement, which has been unanimously supported by the boards of directors of both companies, Great Lakes shareholders will receive 2.2232 shares of Crompton common stock for each share of Great Lakes common stock they hold. The transaction is expected to be tax-free to Great Lakes’ shareholders. The exchange ratio represents a 10.1% premium over Great Lakes’ closing share price on March 8, 2005, and equates to $29.92 per Great Lakes share. Based on the March 8^th price, the transaction is valued at $1.8 billion, including approximately $250 million of Great Lakes net debt and minority interest.

The new company will be owned 51 percent by Crompton shareholders and 49 percent by Great Lakes shareholders on a fully diluted basis. Robert L. Wood, currently chairman, president and CEO of Crompton, will serve in those capacities for the combined company, which will be headquartered in Middlebury, Connecticut. In addition to Robert L. Wood, the board of directors will have five directors from each side, for a total of eleven directors. The new company expects to maintain Crompton’s existing cash dividend level of $.05 per quarter.

“This combination represents an excellent strategic fit between two companies with complementary business portfolios and will create a company with a strong financial profile,” said Robert L. Wood, chairman, president and CEO of Crompton. “It takes us a long way towards our goal of holding leading global positions in true value-added specialty chemicals businesses. In addition to significant operating synergies, we immediately gain greater geographic reach in plastics additives. Building on the increasing profitability of both companies, we see an opportunity with these solid platforms to accelerate our momentum in delivering higher earnings and stronger cash flow.

“Leveraging our recent experience at Crompton, we will execute a well planned, disciplined and comprehensive integration program and expect recurring annual cost savings of $90 million - $100 million, to be achieved in most part by 2006. The combined company will be well capitalized, and will have sufficient liquidity to execute on its business plan,” said Wood.

“We believe this merger provides immediate value creation for our shareholders through the upfront premium and significant synergy opportunities to be realized over the next 18 months,” said John J. Gallagher, III, acting CEO of Great Lakes. “Further, by combining with Crompton, we create a leading global specialty chemicals company with a portfolio of businesses capable of delivering long-term shareholder value. This transaction will result in a company that is stronger and better positioned. The combination creates options and flexibility that operating as two separate companies would not provide.”

The transaction is expected to be accretive to the combined company’s 2006 earnings per share and cash flow per share. In addition to significant cost synergies, the combined company expects to realize cash flow benefits related to utilization of Crompton’s net operating losses. One-time pre-tax closing costs are expected to be approximately $35 million - $40 million. The combined company also expects to incur one-time pre-tax integration costs of approximately $90 million - $100 million.

In addition to Robert L. Wood as chairman and CEO, Karen Osar will serve as CFO, Robert Weiner will head Supply Chain Operations, and Gregory McDaniel, Crompton’s senior vice president, Strategy and New Business Development, will lead the integration activities. Myles Odaniell will head the combined company’s Specialty Chemicals segment, Marcus Meadows-Smith will head Crop Protection and Great Lakes’ Kevin Dunn will head Consumer Products for the combined company. Other management positions will be filled through the integration process, utilizing personnel from both companies.

The transaction, which is expected to close by mid-year, is subject to regulatory approvals, approval by shareholders of both companies and other customary conditions. Morgan Stanley and Citigroup Global Markets Inc. acted as financial advisors to Crompton on this transaction and Merrill Lynch & Co. acted as financial advisor to Great Lakes.

In 2004, Crompton had total revenue of approximately $2.55 billion and a net loss of $34.6 million. Great Lakes had total revenue of $1.6 billion and net income of $62.9 million in the same period. At December 31, 2004, Crompton and Great Lakes had 4,800 and 3,700 employees, respectively.

Document: Announcement to Great Lakes Employees Worldwide (via e-mail)

Timing: March 9, 2005 – 7:00 am EST

SUBJ: Great Lakes to Merge with Crompton Corporation

TO: Great Lakes Employees

FR: John Gallagher, CEO

I am excited to announce that Great Lakes has signed an agreement to merge with Crompton Corporation. We’ll double our size to become the third-largest publicly traded specialty chemical company in the United States. The deal will close mid-year pending shareholder approval.

You might be wondering why we are undertaking this transaction now, when Great Lakes has just undergone so many changes to reposition our company for sustainable growth by focusing on our core businesses—industrial performance products and consumer products. We believe this merger provides immediate value creation for our shareholders through the up-front premium and synergies to be realized over the next 18 months. Further, we have the opportunity to create a leading global specialty chemicals company with a portfolio of businesses capable of delivering long-term shareholder value.

Because competition in the chemical industry is fierce, there has been a trend toward consolidation. This transaction will result in a company that is stronger and better-positioned in the marketplace. The combination creates options and flexibility that operating as two separate companies would not provide.

We will expand our global presence and achieve greater cost savings as we realize production and other efficiencies and share technologies to the benefit of customers.

This merger is only possible due to your determination in providing our customers with excellent service and solutions, lowering costs, increasing productivity and operating our plants and facilities in a safe and efficient manner. You should be proud of the hard work we’ve put in over the past few years to make our company an attractive partner.

We will begin developing an integration plan to bring both companies together as one. Building this new company is a shared effort and your active participation in the integration process will be instrumental in making us the best specialty chemical company in the world.

The new company is expected to be initially known as Crompton Corporation (although other options will be explored) and the new name will be confirmed after closing. Our new company will be led by Bob Wood, Crompton’s current chairman & CEO. The Board of Directors will be comprised of five current directors from Great Lakes and five directors from Crompton, with Bob Wood as chairman.

March 8, 2005

Dear Great Lakes Employees:

On behalf of all of Crompton Corporation, I want to take this opportunity to say that we are pleased and excited at the prospect of our two companies’ coming together to form the third-largest specialty chemicals company in the United States.

I know that with our combined skills and drive, we can achieve the vision of becoming the world’s best specialty chemicals company.

This transaction is a great opportunity. It comes at a time when each of our companies is at a decisive point in determining the next steps to take for our future. We believe that this step will lead to great success.

We will be merging two companies with complementary product and business portfolios, resulting in a company with a true specialty chemicals portfolio with significant growth potential. Each of our companies is a world leader in several product areas, including plastics additives, petroleum additives, brominated performance products, pool chemicals and crop protection. I think this is an impressive list, and that when we combine our companies and share our expertise and technologies, we will add to that list.

Over the next several months, various transition teams will determine the most effective and efficient way to form a new company with its own culture and values. The new company’s headquarters will be in Middlebury, Connecticut. Decisions about facilities and a new corporate structure will be forthcoming.

Part of Crompton’s corporate vision is to be a great place for employees to work and have successful careers, and that vision will extend to our new company. I want employees to be happy to come to work every day and to leave every day with a sense of accomplishment. As a larger company, we will be able to offer more career opportunities.

I anticipate that the talents and expertise you bring to our new company will play a major role in enabling us to achieve our vision to be the best.

I look forward to working with you when this transaction is completed mid-year.

Sincerely,

Bob

Talking Points for Managers

• This merger with Crompton is an exciting development for us with great possibilities.

• At this point in time, we don’t know for sure exactly how the larger company will be structured so I can’t answer any questions about jobs.

• We have our jobs to do, and our customers expect top performance from top people.

• I have no doubt that you will continue to carry on and demonstrate our commitment to innovation and our customer focus.
