Group RGB SWS Group, Inc. Sends Letter to Stockholders Files Definitive Proxy Materials Urging Stockholders to Vote FOR the Adoption of the Merger Agreement with Hilltop Holdings Inc. SWS Board Believes Hilltop Merger Delivers Compelling and Immediate Cash Value; Allows Stockholders to Participate in Significant Upside Potential of Larger, More Diversified Organization DALLAS, October 15, 2014 – SWS Group, Inc. (NYSE: SWS) ("SWS" or the "Company") yesterday sent the following letter to its stockholders recommending that stockholders vote FOR the adoption of the merger agreement with Hilltop Holdings Inc. (“Hilltop”) at the Company’s upcoming Special Meeting of Stockholders to be held on November 21, 2014: October 14, 2014 Dear Fellow SWS Stockholder, You are receiving proxy materials recommending that you vote FOR the proposed merger of SWS with and into a wholly owned subsidiary of Hilltop at the Special Meeting of Stockholders scheduled for November 21, 2014. SWS stockholders of record as of the close of business on October 3, 2014 will be entitled to vote at the Special Meeting. WE URGE YOU TO VOTE “FOR” THE PROPOSED MERGER ON THE ENCLOSED PROXY CARD TODAY The SWS Board of Directors (other than Messrs. Gerald J. Ford and J. Taylor Crandall, who recused themselves), acting upon the unanimous recommendation of the Special Committee, which is comprised entirely of independent directors not affiliated with Hilltop, unanimously concluded that Hilltop’s offer is in the best interest of the Company and its stockholders. SWS stockholders will receive per share consideration of 0.2496 shares of Hilltop common stock and $1.94 of cash, equating to $7.88 per share based on Hilltop’s closing price on March 31, 2014, the trading day on which the SWS Board approved the merger. This represents an approximate premium of: . 30% over the closing price of SWS shares as of January 9, 2014 (the last trading day prior to public announcement acknowledging SWS’s receipt of Hilltop's initial acquisition proposal); . 13% over Hilltop’s initial $7.00 per share acquisition proposal made on January 9, 2014; and . 5% over the closing price of SWS shares as of March 31, 2014. Stockholders should obtain current market quotations for Hilltop common stock.

THE HILLTOP TRANSACTION OFFERS IMMEDIATE VALUE, CERTAIN CASH AND SIGNIFICANT UPSIDE POTENTIAL The SWS Board believes that the proposed transaction with Hilltop provides stockholders with immediate cash value while also allowing you to participate in significant upside potential of the combined company. At closing, SWS’s banking subsidiary, Southwest Securities, FSB, will merge with Hilltop’s wholly owned indirect subsidiary PlainsCapital Bank, while after closing SWS’s broker- dealer subsidiary, Southwest Securities, Inc., will merge with Hilltop’s broker-dealer subsidiary First Southwest Company. The combined company will provide a broad range of consumer, commercial and investment banking and related financial services to individuals, corporations, and investors of all types, broker/dealers, government entities and financial intermediaries. The combined bank will have a stable and low-cost funding profile and the combined broker-dealer will have a more efficient operating platform. Prior to reaching its decision to approve the merger agreement, the SWS Board consulted with SWS’s management, and independent financial and legal advisors, and considered a variety of factors relating to the merger. These factors included: . The Board’s knowledge of Hilltop’s business, including its operations, financial condition, asset quality, earnings and prospects, taking into account input from SWS senior management and information provided by SWS’s financial advisor. . The complementary nature of the SWS and Hilltop businesses, including customer focus, geographic coverage, business orientation and compatibility of the companies' cultures and management and operating styles, and the potential expense-saving and revenue-enhancing opportunities in connection with the merger and the related potential impact on the combined company's earnings. . The large stock component of the merger for SWS stockholders, which will allow you to benefit, on a tax-deferred basis, from the upside of the future performance of the combined company, as stockholders of Hilltop. . The Board’s knowledge of the current environment in the financial services industry and the likely effects on SWS’s potential growth: This includes national, regional and local economic conditions and the interest rate environment, uncertainties in the regulatory climate, increased operating costs resulting from regulatory initiatives and compliance mandates, increasing competition, the current environment for community banks and broker-dealers, and current financial market conditions. . The Board’s belief that the merger consideration with Hilltop exceeds SWS’s likely value as a standalone company. The Board also believes that the value created by this merger would likely exceed the value that would be realized if SWS sold its banking operations and operated its other lines of business on a standalone basis or broke itself up through separate sales of its business lines. This recommendation is based on a number of factors, including, among others: o the risks and uncertainties associated with SWS’s potential performance as a standalone company; o the SWS Board’s analysis of other strategic alternatives available to SWS; and o the financial analyses provided by our financial advisor.

. Absent the merger, SWS would have been required to repay $100 million pursuant to the Company’s 2011 credit agreement and the risks and uncertainties associated with successfully undertaking the financing to make these payments. THE INDEPENDENT SPECIAL COMMITTEE OF THE BOARD CONDUCTED A THOROUGH SALE PROCESS THE SPECIAL COMMITTEE UNANIMOUSLY CONCLUDED THAT THE HILLTOP TRANSACTION IS IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS After Hilltop submitted its written proposal to acquire SWS on January 9, 2014, the SWS Board’s Special Committee led the review of the proposal and any other strategic alternatives. The members of the Special Committee were selected due to their disinterested and non-executive status, their knowledge and experience, and their ability and willingness to devote a significant amount of time to their service on the Special Committee. Together with the Company’s financial and legal advisors, the Special Committee considered a wide range of alternatives to maximize stockholder value, including a sale of SWS to Hilltop or another party, the separate sale of one or more of the Company’s business units or continuing as an independent company, with the goal of maximizing stockholder value. The Special Committee carefully managed the process and maximized the competitive dynamics of the process to obtain the highest price available for all stockholders. During the course of this process, the SWS Board discussed SWS’s business plan, industry trends and the potential for increasing stockholder value through implementation of SWS’s business initiatives. The SWS Board also considered the prospects of SWS, the public markets’ valuation of SWS and other companies in SWS’s industry and the potential challenges to achieving SWS’s business plan. In addition, the SWS Board also discussed the need to repay the $100 million in loans in full on July 28, 2016, or to refinance those loans. On February 13, 2014, the SWS Special Committee instructed its financial advisor to contact third parties that were financially capable and would be likely to receive regulatory approval without material conditions to complete a transaction to acquire SWS. As part of this process, the Company’s financial advisor held discussions with 17 companies (including all of the parties that had contacted SWS or its financial advisor on their own). None of the parties, except for Esposito Global and one other party (“Party A”), continued to pursue a transaction with SWS after the early stage conversation and ultimately neither of these parties submitted a binding proposal to acquire SWS. As a result of extensive negotiations with Hilltop, SWS and its advisors were able to obtain a significant increase in Hilltop’s offer from the beginning of the process to the end of the negotiations, a reduction in the termination fee and an increase in the percentage of merger consideration represented by Hilltop common stock.
