James River Group Reaches Agreement with The D. E. Shaw Group in $575 Million Transaction

June 11, 2007

James River Group Stockholders to Receive $34.50 Per Share in Cash

James River Group, Inc. (James River) (NASDAQ: JRVR) today announced that it has signed a definitive merger agreement under which a Bermuda-based holding company organized by the D. E. Shaw group, a global investment management firm, will acquire James River in a transaction with a total equity value of approximately $575 million.  Under the terms of the merger agreement, stockholders of James River will be entitled to receive $34.50 in cash per share.  The transaction is expected to be completed in the second half of 2007, subject to receipt of stockholder approval and regulatory approvals, as well as other customary closing conditions.  The transaction is not subject to a financing condition and equity commitments for the full amount of the merger consideration have been received from affiliates of the D. E. Shaw group.  James River intends to continue to pay regular quarterly cash dividends until the completion of the transaction.

The Board of Directors of James River has unanimously approved the merger agreement.  A Board Committee formed to evaluate, among other things, the transaction with the D. E. Shaw group, and consisting entirely of non-management directors, developed the material terms of the merger agreement with the assistance of the Board Committee’s financial and legal advisors for consideration by the Board of Directors.

Under the terms of the merger agreement, James River and the Board Committee’s financial advisor will actively solicit superior proposals from third parties during the next 55 calendar days until 11:59 p.m., New York time, on August 5, 2007.  In the event that a superior proposal is received and the merger agreement is terminated during such 55-calendar day period, affiliates of the D. E. Shaw group will receive a termination fee of approximately $7.2 million (approximately 1.25% of the equity value of the transaction), inclusive of transaction fees and expenses.  In addition, subject to the provisions of the merger agreement, James River may, at any time prior to receipt of stockholder approval, respond to unsolicited proposals.  Stockholders holding approximately 45% of the outstanding common stock of James River have agreed to vote in favor of the transaction, unless the merger agreement is terminated, including as a result of James River entering into an agreement for a transaction that is a superior proposal.

James River advises that there can be no assurance that the solicitation of superior proposals will result in an alternative transaction.  James River does not intend to announce developments with respect to the solicitation process until the Board of Directors has made a decision regarding an alternative proposal.

J. Adam Abram, President and Chief Executive Officer of James River, said: “We are pleased with the prospect of having such a well capitalized and committed partner as we go forward. The D. E. Shaw group understands and has embraced our business model and shares our company's approach to the business.  After the transaction closes, we anticipate that a new Bermuda-based reinsurance company will be added to our group.  The inclusion of this entity, and the additional capital associated with it, will add to our group’s capabilities as well as our financial strength. Our employees have accomplished a tremendous amount in a short time.  We look forward to doing more.”

“We are pleased to have entered into a transaction that will offer liquidity to all of our stockholders at a price which is over 90% above the price at which our common stock was first offered to the public a little less than two years ago,” said Dick Wright, Chairman of the Board of James River.  “Moreover, the purchase price represents 2.6 times March 31, 2007 GAAP stockholders’ equity and 14.6 times diluted earnings per share for the 12 months ended March 31, 2007, and is an 11% premium over the 90-day volume weighted average price per share at the signing of the merger agreement.”

Bryan Martin, co-head of private equity of the D. E. Shaw group, said: “We are very pleased to be able to make this investment and to back James River.  Their management team has an outstanding record of operational excellence and we strongly believe they will continue this trend into the future.  We believe their careful approach to underwriting and their diligent expense control provide the company with a powerful competitive advantage.  We look forward between now and closing to presenting our plans to the relevant state and federal regulatory authorities and to what we hope to be a long and profitable association with the entire team at James River.”

J.P. Morgan Securities Inc., the financial advisor to the Board Committee, provided a fairness opinion to the Board Committee and the Board of Directors in connection with the transaction. Skadden, Arps, Slate, Meagher & Flom LLP acted as legal advisor to the Board Committee and Bryan Cave LLP acted as legal advisor to James River in connection with the transaction. Wachovia Capital Markets, LLC served as exclusive financial advisor to the D. E. Shaw group in connection with the transaction.  Debevoise & Plimpton LLP acted as legal advisor to the D. E. Shaw group in connection with the transaction.
