Perini Corporation and Tutor-Saliba Corporation to Combine to Create One of the Leading Building and Civil Contractors

Perini Corporation (NYSE:PCR) and privately-held Tutor-Saliba Corporation today announced that they have signed a definitive agreement to create the premier publicly-traded general contractor in the United States and overseas. The combined company will have enhanced size and scale, including a pro forma backlog at the end of 2007 in excess of $9 billion and over $40 billion of targeted projects. The combination also is expected to enhance Perini’s growth prospects significantly by adding substantial management capacity, client relationships and other resources to Perini’s industry-leading position in the gaming and hospitality markets; by integrating Tutor-Saliba’s highly successful civil construction business with Perini’s civil segment to improve its profitability; and by combining Tutor-Saliba’s successful construction business in Guam with Perini’s PMSI segment to position the combined division to benefit from significant anticipated government spending overseas in the next several years. In addition, this transaction will extend Perini’s geographic diversity, enhance its access to surety bonding and strengthen its management team. The transaction, which is expected to close during the third quarter of 2008, is expected to be accretive to diluted earnings per share beginning in the first full fiscal year of combined operations. Perini is maintaining its existing guidance for fiscal 2008 of diluted earnings per share of $3.50 to $3.75. It is now targeting fiscal 2009 revenue and diluted earnings per share in the range of $7.3 to $7.8 billion and $4.00 to $4.20, respectively, and targeting diluted earnings per share growth in 2010 of between 10% to 20%. A Special Committee of four independent members of Perini’s Board of Directors recommended the transaction to the full Board, which determined that it is in the best interests of Perini shareholders and recommends they vote in favor of it. Ronald N. Tutor, who is Chairman and CEO of Perini and the principal shareholder of Tutor-Saliba, abstained from the unanimous vote by the Perini Board. As a condition of the agreement, Mr. Tutor committed to retain 70% of the shares he will receive in this transaction for at least five years after the closing of the transaction and will serve as Chairman and CEO of the combined companies. Michael R. Klein, Lead Director of Perini who chaired the Special Committee, said: "This transaction significantly enhances the interests of Perini shareholders. It combines, grows and diversifies the best talent of two excellent companies, grows our backlog of booked and targeted projects, and diversifies our reach into promising new segments of the market. Perini has been a highly successful company. Combining with Tutor-Saliba accelerates our growth potential in ways that Perini would not achieve alone. Given our more than 30-year history of successfully working closely with Tutor-Saliba on joint venture projects, we are highly confident that we can integrate the companies seamlessly. In addition, we are securing the continuing leadership of Ron Tutor.” Mr. Tutor said, "This transaction represents a major milestone in the histories of both Perini and Tutor-Saliba. It completely aligns the common business interests of both companies into a single, focused competitor, and secures best-in-class management and operating practices to enhance future growth and earnings for the benefit of the shareholders of both companies. On a personal level, I am excited to be Chairman and CEO of the combined business, in no small part because I understand as well as anyone the opportunities this transaction will create for Perini and its shareholders. As testimony to my belief in the bright future of the business, I have agreed to hold the significant majority of my equity interest – which represents a substantial portion of my personal net worth – in the combined companies for at least five years after the closing of the transaction.” TERMS OF TRANSACTION The transaction has been structured as a tax-free, all-stock merger. Under the agreement, Tutor-Saliba shareholders will receive shares equal to approximately 45% of the common stock of Perini in exchange for their interests in Tutor-Saliba. The total transaction value will be approximately $862 million based on Perini's closing price of $38.10 on April 1, 2008, including assumed adjusted net cash of Tutor-Saliba as of December 31, 2007. The shares of Perini Corporation will continue to trade on The New York Stock Exchange. Upon completion of the merger, the company’s Board of Directors will be expanded to ten directors and will consist of a majority of independent outside directors, after the addition of two new outsiders by Perini and one new nominee by Tutor-Saliba. Mr. Tutor also will have the right to nominate one additional director. Mr. Tutor has agreed to new employment and shareholders agreements to be effective upon closing. These agreements include provisions to ensure his full-time and long-term focus on the combined company, including requirements that he retain all of the shares he will receive in this transaction for six months after the closing date and retain 70% of those shares for at least five years after the closing of the transaction. All of the shares Mr. Tutor will own will be required to be voted to support directors proposed by the Nominating Committee. On all other matters, Mr. Tutor has agreed that he will vote only 20% of his shares at his own discretion and that his remaining shares will be voted in the same proportion as all other Perini shares are voted. The transaction is subject to customary closing conditions, including the approval of Perini’s shareholders and receipt of regulatory approvals. Perini and Tutor-Saliba currently expect the transaction to close during the third quarter of 2008. Until the transaction is completed, both companies will continue to operate their businesses independently. The annual meeting of Perini, previously anticipated for late May, will be set for a date to allow the materials relating to the proposed combination to be voted upon by Perini shareholders, along with the usual annual meeting agenda. The timing of the meeting will depend upon the timing of the receipt of regulatory approvals for the transaction, including clearance from the Securities and Exchange Commission. A TRANSFORMATIONAL TRANSACTION Upon completion of the merger, the company will create the premier publicly-traded general contractor in United States. With its strong presence in the hospitality and gaming industry; strengthened civil public works infrastructure platform in California, Florida, Nevada, the Northeast and Mid-Atlantic; and established presence in the emerging high-growth Guam market, the combined company is well-positioned for improved operating margins and growth. Additionally, the merger presents attractive synergy opportunities that are expected to improve profit margins and provide greater returns to its shareholders, including sharing best practices and leveraging management resources, enhancing operating margin through increased self-performance capabilities and bringing Perini’s PMSI segment into Tutor-Saliba’s Guam operations.

In addition, Perini has started work on the Harold Structures mass transit project in Queens, NY ($139 million) and express toll lanes along Route 95 in Maryland ($87 million). Tutor-Saliba is a privately-held company majority-owned by Mr. Tutor, who also serves as the company’s Chairman and CEO.
