MGIC Investment Corporation and Radian Group Inc. to Merge

MILWAUKEE and PHILADELPHIA, February 6, 2007 — MGIC Investment Corporation (NYSE: MTG), “MGIC”, and Radian Group Inc. (NYSE: RDN), “Radian”, today announced they have agreed to merge, forming a preeminent mortgage and credit risk insurer.

The new company, to be called MGIC Radian Financial Group Inc., will have nearly $15 billion in total assets, more than $290 billion of primary mortgage insurance in force and a financial guaranty portfolio approximating $104 billion of net par outstanding.

The agreement provides for a stock-for-stock merger in which 0.9658 shares of MGIC common stock will be exchanged for each share of Radian common stock. The merger is intended to qualify as a “tax-free reorganization” for U.S. shareholders. Based upon the closing stock prices of both companies on February 5, 2007, the pro forma combined market capitalization of the new institution would be approximately $10 billion.

Curt S. Culver, current chairman and chief executive officer of MGIC, will serve as chairman and chief executive officer of the combined company. S.A. Ibrahim, current chief executive officer of Radian, will serve as the president and chief operating officer of the combined company. Mr. Ibrahim will succeed Mr. Culver as chief executive officer of MGIC Radian Financial Group Inc. in 2009 and as chairman in 2010.

The board of directors will initially be comprised of six members designated by MGIC and five members designated by Radian, but promptly following the consummation of the merger, MGIC Radian Financial Group Inc. will nominate for director an additional Radian director to stand for election by the combined company’s shareholders. The combined company’s headquarters will be located in Milwaukee, Wisconsin, and have operations in New York, Philadelphia, and internationally.

The combined company will have a broad and balanced mix of businesses including domestic mortgage insurance, financial guaranty, financial services and international credit enhancement.

“Radian shares MGIC’s passion for delivering superior customer service, and the combined company will be in an excellent position to raise these service standards even higher,” said Mr. Culver. “Our companies have similar goals and shared values regarding increasing shareholder value. We will take a deliberate, methodical approach to integrating our companies, making certain that customers continue to receive high quality service and that our shareholders realize the potential benefits of this merger.”

Mr. Ibrahim also expressed his enthusiasm for the merger, saying: “I am confident the new MGIC Radian Financial Group will emerge as a premier U.S. and international mortgage insurer and credit enhancement provider, delivering superior shareholder returns by combining the best talent, analytics, systems and processes, and the disciplined risk management cultures of both companies.

“Our businesses complement each other in many ways, and, led by one of the most experienced management teams in the business, we will have an even greater ability to meet the credit enhancement needs of capital markets worldwide,” Mr. Ibrahim continued. “The appeal of this merger is compelling by any measure – strategically, financially and operationally.”

The combined company expects to realize aggregate cost savings of $128 million, pre-tax. Approximately 75 percent of this benefit is expected to be realized in 2008 and the full run-rate of cost savings is expected to be realized in 2009. The expected annual cost savings represent approximately 24 percent of the pro forma combined operating expense base. The combined company expects to incur restructuring costs of approximately $125 – $150 million, after tax.

The transaction has been unanimously approved by each company’s board of directors and is expected to be completed in the fourth quarter of 2007, subject to regulatory and shareholder approvals. Assuming the achievement of planned cost reductions, on a GAAP basis the transaction is expected to be 2.8 percent accretive to MGIC’s earnings per share in 2008 and 6.3 percent accretive to MGIC’s earnings per share in 2009. On a cash basis, which excludes the impact of non-cash items such as the amortization of intangibles, the transaction is expected to be 6.7 percent accretive to MGIC’s earnings per share in 2008 and 9.5 percent accretive to MGIC’s earnings per share in 2009. To Radian, on a GAAP basis the transaction is expected to be 4.7 percent accretive to Radian’s earnings per share in 2008 and 8.2 percent accretive to Radian’s earnings per share in 2009.

As part of the transaction, it currently is expected MGIC Radian Financial Group will initially pay a dividend of $0.25 per share per quarter, which is the current MGIC quarterly dividend rate and represents an increase of $0.23 per share per quarter for Radian shareholders. All dividends are subject to applicable law and the discretion of the applicable company’s board of directors.
