SRA to be acquired by Providence Equity Partners

for $31.25 per share

• SRA shareholders to receive $31.25 per share in cash

• Transaction valued at $1.88 billion

• SRA to become a privately held company

FAIRFAX, Va. and PROVIDENCE, R.I., April 1, 2011 — SRA International, Inc. (NYSE: SRX), a leading provider of technology and strategic consulting services and solutions to government organizations and commercial clients, today announced it has entered into a definitive merger agreement under which SRA will be acquired by an affiliate of Providence Equity Partners in an all-cash transaction.

Pursuant to terms of the agreement, SRA shareholders will receive $31.25 in cash for each share of common stock, for a total value of approximately $1.88 billion. The transaction represents a 10.2% premium based on the closing price of $28.36 on March 31, 2011 and a premium of 52.8% over the closing price of $20.45 on Dec. 31, 2010, the company’s unaffected share price.

SRA’s Board of Directors – acting upon the recommendation of a Special Committee consisting of independent and disinterested Directors and in conjunction with the Special Committee’s outside financial and legal advisors – unanimously approved the transaction and recommended that SRA shareholders approve the transaction, with SRA Founder and Chairman Dr. Ernst Volgenau abstaining.

Dr. Volgenau said, “We believe in the merits of this transaction, which serves the best interests of our shareholders, as well as those of our 7,300 employees and more than 1,400 contracts with customers. We also look forward to partnering with Providence, whose values and culture are consistent with SRA’s longstanding ethic of honesty and service. We believe these characteristics are critical as we continue to build SRA and sustain its competitive positioning for the future.”

Julie Richardson, a Managing Director at Providence, said “The government information services market is a highly attractive area of investment for Providence, and SRA is a leading innovator within the national security, civil government, global health and intelligence sectors.” “Under Ernst’s remarkable stewardship since founding the company over 32 years ago, SRA has built a strong culture of integrity and a sterling reputation for high-quality service that differentiates the company from its competitors and positions them well to compete and win in this market. We are excited about partnering with Ernst and the SRA management team to build lasting value for the company, its employees and its customers.”

Following the completion of the transaction, SRA will remain headquartered in Fairfax, Va., and maintain its offices around the world. The company will continue to be led by its existing senior management team. Dr. Volgenau will continue to serve as Chairman of the SRA Board.

The transaction is subject to approval of a majority of the outstanding shares of SRA, as well as a majority of the outstanding shares of SRA Class A Common Stock (excluding shares beneficially owned by Dr. Volgenau), and other customary closing conditions and regulatory approvals. The transaction is anticipated to close during the first quarter of the SRA 2012 fiscal year, which begins on July 1, 2011. Upon closing, SRA will become a privately held company. At the request of Providence, Dr. Volgenau will roll over a portion of his existing SRA equity interest and continue to be a significant shareholder in the privately held company.

Dr. Volgenau, who owns a total of approximately 11.8 million shares of Class A and Class B common stock, representing 21% of total shares outstanding and 71% of voting rights, has agreed to vote his shares for approval of the merger. However, in the event that the merger agreement is terminated, Dr. Volgenau will be released from this obligation.

Under the terms of the merger agreement, SRA may solicit acquisition proposals from third parties for a 30-day “go-shop” period from the date of the merger agreement. It is not anticipated that any developments will be disclosed with regard to this process unless the SRA Board of Directors makes a decision with respect to a potential superior proposal. The merger agreement provides Providence with a customary right to match a superior proposal. There is no guarantee that this process will result in a superior proposal.

The agreement between SRA and Providence concludes a process that began in October 2010, when SRA’s Board of Directors formed a Special Committee of Independent Directors to explore the possibility of an acquisition. At that time, the Special Committee retained Houlihan Lokey as its outside financial adviser and Kirkland & Ellis LLP as its special counsel. Both firms are independent of SRA management. SRA, acting through the Special Committee, conducted a comprehensive process that included strategic and financial buyers. This process resulted in the current agreement with Providence.

Given published speculations over the past four months, it should be noted that SRA never received, and thus never rejected, an offer at an erroneously reported aggregate value of $2 billion. Indeed, the

only figure ever communicated to SRA from that third party was a December 1, 2010 highly conditioned expression of interest in the range of $30-$31 per share which did not materialize.

The transaction will be financed through a combination of equity and debt. The debt financing is provided by BofA Merrill Lynch and Citigroup Global Markets Inc.

Houlihan Lokey acted as financial advisor and Kirkland & Ellis acted as legal advisor to the Special Committee of SRA’s Board of Directors in connection with the transaction. Citigroup Global Markets Inc. and BofA Merrill Lynch acted as financial advisers and Debevoise & Plimpton served as legal counsel to Providence in connection with the transaction.
