FCSTONE GROUP, INC. TO MERGE

Deal Creates a Leading Global Provider of Consulting and Trade Execution Services

NEW YORK, NY and KANSAS CITY, MO – July 2, 2009 – International Assets Holding Corporation (Nasdaq: IAAC) (“International Assets”) and FCStone Group, Inc. (Nasdaq: FCSX) (“FCStone”), today announced that they have signed a definitive agreement to merge in a share swap that creates a combined company with a market capitalization of approximately $260 million.

Management of International Assets and FCStone will host a conference call at 11:00 a.m. Eastern Time, today, July 2, 2009, to discuss the transaction. Details regarding the call appear at the end of this press release.

The transaction, structured as a merger of equals, will create a combined entity that will serve more than 10,000 customers from an employee base of 650 people and offices in eleven countries. Based on reported results for the last four fiscal quarters for International Assets and FCStone, the combined company has an annual revenue base of approximately $411 million and as of the most recent balance sheet dates, total combined assets valued at $2.3 billion and total combined shareholders equity of $253 million.

International Assets is a leading financial service provider to the precious metals, foreign currency and international equities trading markets, and also has expertise in international debt underwriting and asset management. FCStone provides risk management consulting and transaction execution services to commercial customers throughout the commodities value chain. FCStone will continue to operate independently after the merger under its existing brand, leadership and employee base.

Under the merger agreement, FCStone common shareholders will receive .2950 shares of International Assets common stock for each share they own. International Assets’ current stockholders will own approximately 52.5% of International Assets following the merger and FCStone’s current stockholders will own the remaining approximately 47.5%. Directors and management of the combined company will own approximately 26% of the equity. The merger is expected to be tax free to stockholders of both companies. International Assets will continue to list its common stock on the Nasdaq Global Market and trade under the symbol IAAC.

“International Assets and FCStone bring together complementary strengths and a customer-centric focus to create a unique financial services company,” said Sean O’Connor, who will be Chief Executive Officer of the merged company. “FCStone’s exchange and OTC platforms combined with our geographic diversity and strong and liquid capital base create immediate growth opportunities for the merged company, while the expansion of both companies’ customer bases will drive value creation over time. International Assets’ strong performance track record is based on a philosophy of protecting capital through robust risk management and driving strong double digit equity returns through a disciplined capital allocation approach.”

Pete Anderson, FCStone’s President and CEO commented, “International Assets is a like-minded partner that shares a focus on the customer and also has the capital base to support our many growth opportunities both domestically and around the globe.” Anderson will serve as President and a director of International Assets and continue as CEO of FCStone. “We will continue doing what we do best as part of the new International Assets: provide our unique commodity risk management expertise to customers across the agriculture, energy, food service and other verticals we serve. At the same time, we will leverage our partner’s global presence and liquidity to accelerate our growth plans, especially in targeted international markets, while strengthening

and enhancing our capabilities and product offerings. This transaction is a great opportunity for FCStone, our customers, our employees and our shareholders.”

In addition to O’Connor and Anderson, the merged company’s executive management team will include International Assets’ Scott Branch as Chief Operating Officer, Brian Sephton as Chief Legal and Governance Officer and FCStone’s Bill Dunaway as Chief Financial Officer. International Assets will have a 13-seat board of directors, with seven seats designated by International Assets and six by FCStone. The position of Chairman will alternate for the first two years. International Assets will be headquartered in New York, NY, and FCStone will continue to operate from its offices in Kansas City, MO and West Des Moines, IA.

Strategic Rationale and Strategies for Growth

This merger comes at a time when large financial services companies are retreating to their core areas of strength in a volatile marketplace, while many smaller players lack capital and are seen as more risky counterparties than in the past. International Assets and FCStone believe that this environment presents opportunities for companies to take market share in key categories. At the same time, today’s environment demands a comprehensive and systematic focus on risk management. The International Assets management team brings extensive risk management experience and techniques to its business and will take responsibility for this crucial function in the merged company.

The merged entity expects to drive growth by adhering closely to the customer centric strategies employed to date by both International Assets and FCStone. Key strategies for growth include:

• Leveraging the benefits of the combined trading and execution platform to enhance services to customers in a capital efficient manner;

• Building out the customer bases of the respective businesses by capitalizing on the merged company’s global presence and broad set of value-added services;

• Seeking “tuck-in” acquisitions to supplement organic growth; and

• Taking a disciplined approach to capital allocation that emphasizes protecting earnings, selecting opportunities featuring equity returns in the high teens, and maintaining rigorous risk management.

Transaction Closing

The transaction has been unanimously approved by the boards of directors of both companies. Both companies must secure the approval of their respective shareholders and expect to file a registration statement and preliminary proxy materials with the SEC within the next 30 days. The transaction is subject to expiration or termination of the requisite waiting period under the Hart-Scott-Rodino Act and the approval of the stockholders of International Assets and FCStone. It is currently anticipated that the transaction will close in the fourth calendar quarter of 2009.
